Description

Technical Field

[0001] The utility model relates to the field of polyurethane plates, in particular to a laminating machine for processing polyurethane plates. Background Art

[0002] With moisture-proof and waterproof properties, the main application areas of polyurethane insulation boards are bumpers, body panels, trunk lids and corresponding fenders. Polyurethane materials are widely used in the manufacture of automobile bumpers, body panels and other parts due to their light weight, high strength, wear resistance and corrosion resistance.

[0003] In the existing technology, when producing polyurethane insulation boards, it is necessary to use a laminator to press the polyurethane board and other interlayers. The laminator is also called a press, which is a mechanical device used to press objects into one. Its working principle mainly includes three steps: feeding, pressing and discharging:

[0004] The laminating machine's feeding system feeds the objects to be laminated into the machine. This process can be done manually or with automated equipment.

[0005] The feeding system usually consists of conveyor belts, rollers or other devices to ensure that the objects enter the pressing area smoothly;

[0006] The object enters the pressing area. In the pressing area, the pressing machine will apply a certain force to press the various parts of the object tightly together. The pressing force can be generated by a hydraulic system, a pneumatic system or a mechanical device. This force makes the structure of the object more stable and prevents it from loosening or separating.

[0007] During the lamination process of polyurethane insulation boards, adhesive is first sprayed on the polyurethane surface, and then gauze is added to adhere to the adhesive, and then the board enters the laminating machine for lamination. Traditional adhesive spraying usually uses an independent drive machine to spray the adhesive. In order to further reduce the drive unit and reduce costs, the utility model proposes a laminating machine for polyurethane board processing. Utility Model Content

[0018] One end of the transmission belt is sleeved and meshed with an outer wall of one end of the second gear and extends to the outside of the frame. The transmission belt is used for synchronously driving the push block to rotate circumferentially.

[0039] The transmission rod 401 is eccentrically connected to the end of the shaft of the conveyor belt 2, and the transmission rod 401 is used to synchronously drive the rotating wheel 402 to rotate;

[0040] The rotating wheel 402 is rotatably connected to the outer wall of the frame 1, and the rotating wheel 402 is used to synchronously drive the first gear 403 to rotate;

[0041] The first gear 403 is fixed to the end of the shaft of the rotating wheel 402, and the first gear 403 is used to drive the second gear 404 to rotate;

[0042] The second gear 404 is rotatably connected to the inner wall of the frame 1, and the second gear 404 is used to drive the transmission belt 405;

[0043] One end of the transmission belt 405 is sleeved and meshed with the outer wall of one end of the second gear 404 and extends to the outside of the frame 1. The transmission belt 405 is used to synchronously drive the push block 408 to rotate circumferentially;

[0044] The guide unit includes a nozzle 406, a positioning block 407, and a push block 408;

[0048] In this embodiment: It should be supplemented that: the conveyor belt 2 is located at the front end of the feeding port of the laminating machine 5, and another conveying component for conveying the gauze is provided above the conveyor belt 2;

[0049] When using this device, the driving motor connected to the shaft of the conveyor belt 2 is started to drive the conveyor belt 2, and the driven conveyor belt 2 drives the transmission rod 401 connected to the eccentric rotation of the shaft end to rotate circumferentially synchronously, and the runner 402 connected to the eccentric rotation of the other end of the transmission rod 401 will also be driven synchronously, and the runner 402 will synchronously drive the first gear 403 to rotate, and the rotating first gear 403 will give the second gear 404 a rotating force, and the second gear 404 that is rotated by the force will synchronously drive the transmission belt 405 to transmit, so that the push block 408 fixed on the inner side of the transmission belt 405 moves with the transmission of the transmission belt 405, and the moving push block 408 pushes the positioning block 407 to move axially along the inner side of the transmission belt 405, so that the positioning block 407 The nozzle 406 with a fixed end moves synchronously to spray the upper surface of the plate 3.

Thereafter, the push block 408 continues to move under the action of the transmission belt 405 to drive the nozzle 406 and the positioning block 407 to move, thereby achieving the purpose of driving the nozzle 406 to move back and forth, thereby spraying the upper surface of the plate 3, further reducing the number of driving units, and achieving the purpose of reciprocating spraying on the upper surface of the plate 3 while the conveyor belt 2 is being transported;

[0051] Please refer to Figure 1-Figure 3 The outer wall of the positioning block 407 is rectangular as a whole, and the inner wall of the frame 1 is formed with a slide groove for axial movement of the positioning block 407. The positioning block 407 is fixedly connected to the nozzle 406 by a cylindrical shaft rod, and the inner side of one end of the push block 408 is rotatably sleeved with the cylindrical shaft rod between the nozzle 406 and the positioning block 407.
