Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a leveling mechanism of a laminating machine. Background Art

[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. They are special equipment used for paper, boards, and film mounting. After being pressurized by rubber rollers and heating rollers, they are combined together to form a paper-plastic product.

[0003] At present, the existing laminating machine (such as patent number: CN215661954U) discloses an aluminum plate laminating machine with a leveling and compacting structure. Through the set leveling roller, rubber pad, spring and fixed seat, the leveling roller is convenient for the laminating machine to level the covered aluminum plate, and the fixed seat is convenient for the laminating machine to place the leveling roller horizontally above the placement table. The spring and rubber pad are convenient to increase the adjustability of the height of the leveling roller.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the height is adjusted by springs and rubber pads. After long-term use, the spring elasticity will weaken and compress the volume. In addition, the rubber pads will easily wear and become thinner due to long-term stress, causing parts to loosen, which can easily cause changes in height and affect the coating of the sheet. At the same time, regular maintenance and replacement will increase the cost of use. Utility Model Content

[0005] 1. Technical issues to be resolved

At the same time, regular maintenance and replacement increase the cost of use.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A leveling mechanism of a laminating machine comprises a laminating machine body, an adjusting mechanism is installed inside the laminating machine body, the adjusting mechanism comprises a mounting plate, a top plate, and a second driving rod, a supporting frame is fixedly installed inside the laminating machine body, a driving box is fixedly installed at the bottom end of the top plate, the same positioning roller is arranged on the inner sides of the two mounting plates, and slide plates are slidably installed on both side ends of the top plate.

By driving the second driving rod to extend and retract, the second driving rod is allowed to extend and retract inside the laminating machine body, and the second driving rod drives the top plate to move upward. The movement of the top plate allows the second driving rod to drive the slide plate to extrude the inner wall of the guide groove. The top plate moves upward to adjust the distance with the support frame. At the same time, the top end of the support frame is flush with the inside of the laminating machine body, so that plates of different thicknesses can be processed. At the same time, the second driving rod directly drives the positioning roller to extrude the top end of the plate. The structure is simple and compact, and stable support can be provided.

[0020] The embodiment of the present application provides a leveling mechanism for a laminating machine, which effectively solves the problem of adjusting the height by using a spring and a rubber pad. After long-term use, the spring elasticity weakens and the volume is compressed. In addition, the rubber pad is prone to wear and thinning due to long-term stress, which leads to loosening of components, easy changes in height, and affects the lamination of the plate. At the same time, regular maintenance and replacement increase the cost of use. By driving the second drive rod to retract and extend, the second drive rod is retracted and extended inside the laminating machine body, and the second drive rod drives the top plate to move upward. The movement of the top plate allows the second drive rod to drive the slide plate to extrude the inner wall of the guide groove. The top plate moves upward to adjust the distance from the support frame. At the same time, the top end of the support frame is flush with the inside of the laminating machine body, so that plates of different thicknesses can be processed. At the same time, the second drive rod directly drives the positioning roller to extrude the top of the plate. The structure is simple and compact, and stable support can be provided.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the height is adjusted by the spring and the rubber pad. After long-term use, the spring elasticity weakens and the volume is compressed. The rubber pad is easily worn and thinned due to long-term force, resulting in loose parts, which is easy to change the height and affect the sheet coating. At the same time, regular maintenance and replacement increase the cost of use. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a leveling mechanism of a laminating machine, including a laminating machine body 1, an adjusting mechanism is installed inside the laminating machine body 1, the adjusting mechanism includes a mounting plate 13, a top plate 14, and a second driving rod 17, a support frame 11 is fixedly installed inside the laminating machine body 1, a driving motor inside the laminating machine body 1 drives the driving wheel at the top of the support frame 11 to rotate, rubs with the filter plate, drives the filter plate to move to one side after laminating, and drives the second driving rod 17 to retract and retract through the laminating machine body 1, the second driving rod 17 generates a downward force on the top plate 14, so that the top plate 14 drives the positioning roller 12 to roll and squeeze the top of the filter plate to level the film, a driving box 15 is fixedly installed on the bottom end of the top plate 14, the same positioning roller 12 is arranged on the inner sides of the two mounting plates 13, and slide plates 21 are slidably installed on both side ends of the top plate 14.

[0024] The ends of the slide plates 21 are fixedly installed with reset rods 19, and the two side ends of the drive box 15 are fixedly installed with first drive rods 16. The two inner side walls of the laminating machine body 1 are provided with guide grooves 18. By driving the second drive rod 17 to extend and retract, the second drive rod 17 is extended and retracted inside the laminating machine body 1, and the second drive rod 17 drives the top plate 14 to move upward. The movement of the top plate 14 allows the second drive rod 17 to drive the slide plates 21 to squeeze the inner side walls of the guide grooves 18. The inner side walls of the guide grooves 18 are provided with a plurality of sockets. The top of the slide plates 21 is designed in an arc shape. The movement of the top plate 14 allows the slide plates 21 to squeeze the inner side walls of the guide grooves 18, and a force is applied to the slide plates 21. The slide plates 21 are forced to enter the interior of the top plate 14, squeezing the top of the reset rod 19. The inner side walls of the guide grooves 18 are provided with a plurality of sockets. Transmission shafts are installed on both sides of the support frame 11, which are connected to the driving wheels at the top of the support frame 11.

[0025] Working principle:

[0026] The first step is to put the aluminum plate into the laminating machine body 1 through the material port on one side during use. A conveying mechanism and a laminating mechanism are installed inside the laminating machine body 1. The film is preheated by a heating device first, and the film and the filter plate are driven respectively by rollers. The rollers extrude the film so that the film fits the top of the filter plate for laminating. The second driving rod 17 drives the top plate 14 to move downward, and the mounting plate 13 drives the positioning roller 12 to extrude the coated filter plate, so that the filter plate moves between the support frame 11 and the top plate 14. At the same time, the two sides of the support frame 11 are connected to the transmission shaft, and the driving motor inside the laminating machine body 1 drives the driving wheel at the top of the support frame 11 to rotate, rub against the filter plate, drive the filter plate to move to one side after laminating, and drive the second driving rod 17 to retract through the laminating machine body 1. The second driving rod 17 exerts a downward force on the top plate 14, so that the top plate 14 drives the positioning roller 12 to roll and extrude the top of the filter plate to level the film.

[0027] In the second step, by driving the second driving rod 17 to extend and retract, the second driving rod 17 is extended and retracted inside the laminating machine body 1, and the second driving rod 17 drives the top plate 14 to move upward. The movement of the top plate 14 allows the second driving rod 17 to drive the slide plate 21 to squeeze the inner wall of the guide groove 18. The inner wall of the guide groove 18 is provided with a plurality of sockets. The top of the slide plate 21 is designed in an arc shape. The movement of the top plate 14 allows the slide plate 21 to squeeze the inner wall of the guide groove 18, and a force is applied to the slide plate 21. The slide plate 21 is forced into the interior of the top plate 14, squeezes the top of the reset rod 19, and moves upward through the top plate 14 to adjust the distance from the support frame 11. Plates of different thicknesses can be processed. The rod 17 directly drives the positioning roller 12 to squeeze the top of the plate. The structure is simple and compact, and can provide stable support. At the same time, after the top plate 14 stops moving, the reverse force of the reset rod 19 is used to push the slide plate 21 to slide on the side end of the top plate 14 and insert it into the guide groove 18 for rapid positioning. The first driving rod 16 on both sides is driven to extend and retract by the driving box 15. The first driving rod 16 applies the same thrust to the two mounting plates 13. The mounting plate 13 moves at the bottom end of the top plate 14, and the distance between the two mounting plates 13 is expanded. At the same time, the side end of the mounting plate 13 moves into the guide groove 18. By separating the two mounting plates 13, it is convenient to replace the positioning roller 12.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
