Dynamoelectric Laminating and Stacking Machine

Having a laminating and stacking machine at home can be a wonderful way to keep your papers, documents, and files organized. However, you need to make sure that you pick the right model for your needs. A slender and sleek design can help you achieve the results you want without wasting time. Plus, a dynamoelectric model can save you money.

Easy to operate

Whether you are a professional or a home user, a laminating and stacking machine can make your work much easier. This simple device requires only a few minutes to warm up, and once you are ready to use it, it will be ready to work in a flash.

ALM series laminators feature a convenient digital control panel that allows you to adjust the laminating temperature on the fly. This is especially useful when laminating different paper weights. The control pad is also equipped with a “Stop” button, so you can stop the laminating process in mid-project.

ALM series laminators accept prints up to 13″ x 19″, and have a robust 200 sheet capacity. These machines also feature automated feed and trimming features. They offer an automatic clamping system to ensure a smooth laminated paper.

This machine features an integrated suction feeder to pick up and trim preformed fiber trays. Aside from the suction feeder, the machine is also equipped with a high-speed bump separator and a non-stick roller to handle heavy-duty lamination.

The machine also features a bottom sheet feeder, which is designed to handle materials with thickness from 0.6 mm to 10 mm. This conveyor uses suction cups to pick up the top sheet and feed it into the bottom. The machine also has an adjustable tension control for the supply roll, which is located on the mandrel.

The machine is equipped with a polycarbonate safety shield that is made in the U.S. and comes with a one-year warranty. Besides being durable and made of recyclable material, the shield is made of clear polycarbonate, so it will not conduct heat.

It takes three to five minutes to heat up a Crenova thermal laminator. Once you have the film loaded into the container, the machine will automatically adjust the temperature to suit the pouch’s thickness. It also has a jam-release function. The machine’s aluminum thermal conductivity pipe helps to produce wrinkle-free finished products.

Reduces cost of a large dynamoelectric machine

Optimising the size and performance of a dynamoelectric laminating and stacking machine is a difficult task. A number of parameters influence the optimization process. These include the rotor width, diameter and the gap between the rotors. These are all dependent on the crucial parameters of your application.

The present invention utilises a new design approach to optimise the inner diameter of the stator lamination plates. This results in a smaller gap between the rotors. This gap reduces the torque ripple and provides an improved sub-harmonics distribution. This allows the machine to reach higher torques and increase power.

In addition, the lamination stack height is increased to achieve greater flux density in the tooth portion of the stator. This leads to smaller end turns on the lamination stack end faces. In addition, a double layer winding structure reduces the cogging torque.

Another scalar quantity is the permeability of the conductors. This is not as easy to calculate Laminating and stacking machine as the permeability of the airgap. In addition, there is more research needed in this area.

The Maxwell Stress Tensor is a great tool for calculating electromagnetic forces in an electrical machine. This is especially useful in a machine with a magnetic circuit. It can be used with a scalar magnetic potential and vector magnetic potentials. The equation for the Maxwell Stress Tensor is given in the following equation: 5.21.

The present invention also optimises the ratio of the inner diameter to the outer diameter of the stator lamination plates. A ratio of BT1 / BY1 was found to be about one. This is a good way to optimise the efficiency of a machine.

Stacking factor

Stacking and lamination is an important process used in making an iron core for an electrical machine. It enables the machine to amplify magnetic fields generated by current-carrying coils. This is done in the form of sheets of electrical steel that are stacked and bonded together. Depending on the manufacturing process, the resultant stack may or may not be perfectly flat.

Using the correct stacking factor will increase the amplification of magnetic fields and reduce the overall power consumption of the machine. Traditionally, this is achieved by applying a varnish coat to the laminations. However, many producers do not offer stacking factors for their products. Therefore, calculating the best stacking method for an electrical transformer requires a bit of math.

A lamination stacking machine is designed to hold and stack a variety of different lamination sizes. These machines usually operate in one-eighth-inch increments. In addition to the size of the laminations, the thickness of the laminations also matters. The thicker the laminations, the greater the stacking factor.

A lamination stacking machine includes a head, a supporting base, and a reciprocating plate. The latter is a drive mechanism that engages the slide of the head to reciprocate. This drives the laminations into an assembly relationship with the coil. The machine can be used to stack EI-19 to EI-162 laminations. It is able to stack 300 pieces per minute.

The lamination stacking machine is also equipped to accommodate a range of interchangeable heads. The head is comprised of all the mechanisms that engage the laminations. In particular, it includes the gauging and picking mechanisms, as well as all the mechanisms that slide and hold the laminations.

Indexing functions

Usually indexing is referred to as rotation, but the term can also refer to other controlled movements. Various methods of indexing can be used to position a workpiece at a precise angle or interval, often with great accuracy. This is especially useful in mass production. It may be done in conjunction with Information Technology (IT) or without IT.

Indexing can be a simple and reliable process. This is facilitated by a cam operated indexing drive system that eliminates all drive components between the cam driven output shaft and the draw rolls. Typically, cams engage cooperating groups of cam followers that determine the dwell time and motion characteristics of the indexing.

In accordance with example 1 of the present disclosure, a laminated precursor article 700 includes at least one indexed prepreg composite sheet 300. Each indexed prepreg composite sheet 300 includes a set of indexing openings 306. These indexing openings are arranged in pattern angles relative to the longitudinal direction of the fibers. These indexing openings are located on portions of the laminated precursor article 700 that will be trimmed. This is achieved by positioning the laminated precursor article 700 over the indexed prepreg composite sheet 300.

The indexed prepreg composite sheet 300 can be conveyed by a conveyor system 104 to a region forming apparatus 108. This apparatus is configured to replace non-impregnated regions 310 with indexing openings 306.

This procedure is then repeated for each sub-sheet. The indexed prepreg composite sheet 300 is stacked into a desired finished configuration. Each stack is then rolled out of the stacking area. The stacked laminations can be trimmed to maintain a precise pass line height.

Feeder

Generally, a laminating and stacking machine has a feed mechanism that feeds individual sheets to a laminator. As stacked sheets enter the laminator, their leading edges must be square with each other and perpendicular to the feed path. The feeding apparatus is a movable support structure that holds a stack of sheets and keeps them square with the laminator.

The feeder includes a guide plate that faces the leading edges of the stack of sheets. This plate helps to position the leading edges perpendicular to the feed path. It also allows the operator to control the spacing between individual sheets. The feeder may be manually moved from one position to another.

The laminating and stacking machine of the present invention includes a first elongated member 26, a second elongated member 27, a wheel assembly 37 and 38, a vertically movable tray 75, a stacking base 2 and a feeder motor 45. The elongated members 26 and 27 are mechanically coupled to the wheel assemblies 37 and 38. The feeding means are positioned close to the conveyor at the input end of the laminating and stacking machine.

The elongated members 26 and 27 also contain channels that are utilized by the feeder 11 to ride within. A locking device may be provided to hold the feeder in a desired position.

The system also has an uppermost paper position detecting means that detects the arrival of the uppermost sheet at a predetermined position. This information is used by the control unit to determine the position of the top sheet in the stack. This information is used to instruct the control unit to elevate the stack in a direction that will transport the uppermost sheet to the traction device. The traction device is then used to transfer the top sheet to the conveyor.
