Description

Technical Field

[0001] This utility model specifically relates to the field of sheet coating equipment technology, and more specifically to an automatic coating machine with a tail roller. Background Technology

[0002] Automatic laminating machines are commonly used equipment in the process of composite board manufacturing. By smoothly covering the sheet with a protective film, they effectively protect the process surface of the sheet from being scratched and ensure that the material products can be collected, stacked, transported and transferred after lamination. The film roll is mounted on the unwinding mechanism. The unwinding shaft is driven by a motor and automatically adjusts the unwinding tension according to the substrate conveying speed. The substrate and film meet at the laminating roller and are pressed onto the substrate surface by one or more sets of rubber pressure rollers: the upper roller applies pressure and the lower roller provides support.

[0003] However, in practice, it has been noted that existing automatic laminating machines have insufficient traction force during sheet lamination due to the excessively large gap between the two sets of pressure rollers. Furthermore, poor connection between the sets of pressure rollers can easily lead to jamming and damage during sheet lamination, resulting in frequent abnormal operations, increased process defects, and efficiency losses. Utility Model Content

[0004] The purpose of this invention is to provide an automatic laminating machine with a tail roller. A stainless steel silent tail roller is installed between two sets of pressure rollers. The tail roller's height and balance are adjustable at both ends, reducing the distance between the roller sets and improving the smoothness of sheet conveying. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic laminating machine with a tail roller includes a sheet laminating machine, in which two pressure rollers are movably connected, and one of the pressure rollers is also provided with a sheet conveyor belt on its side. An intermediate roller is provided between the two pressure rollers, and an adjustment bracket is provided at both ends of the intermediate roller. The adjustment bracket on either side of the intermediate roller is provided with two sets of mutually staggered arrangements.

[0006] As a further technical solution of this utility model, the intermediate roller is mainly composed of a receiving roller, and both ends of the receiving roller are integrally provided with connecting shafts that are movably connected to the adjusting bracket.

[0007] As a further technical solution of this utility model, the adjusting bracket includes a threaded adjusting rod and an internal threaded sleeve with threaded transmission, wherein the end of the threaded adjusting rod is provided with a support sleeve that is movably connected to the connecting shaft.

[0008] As a further technical solution of this utility model, the side of the internal threaded sleeve is integrally provided with a support connecting rod, and a fixing hole plate is sleeved on the outside of the support connecting rod. The inner side of the fixed hole plate is integrally provided with a hollow sleeve that cooperates with the support rod, and the hollow sleeve is rotatably engaged with the end of the support rod away from the internal threaded sleeve.

[0009] As a further technical solution of this utility model, each of the support bushings is interference-fitted with a silent bearing, and the inner ring of the silent bearing is interference-fitted with the connecting shaft to reduce the noise when the receiving roller rotates. In addition, a sealing ring is provided between the support bushing and the connecting shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a receiving roller between two pressure rollers to guide the film material passing under the pressure rollers, reduce the distance between the two pressure rollers, and prevent the film material from getting stuck when passing through the gap between the two pressure rollers. This ensures the smooth flow of the film material through the pressure rollers and also ensures the smoothness of the sheet material during the conveying process, thereby improving the bonding quality between the film material and the sheet material. In this invention, two intersecting adjustment brackets are provided at both ends of the receiving roller. Rotating one of the threaded adjustment rods pushes the receiving roller upward through the threaded engagement between the threaded adjustment rod and the internal threaded sleeve. Furthermore, based on the two intersecting threaded adjustment rods, not only can the height of the receiving roller be adjusted, but also the distance between the receiving roller and any of the pressure rollers can be adjusted. Precise adjustment can be made as needed, thereby improving the accuracy of the adjustment of the receiving roller. This utility model allows the fixing plate to be fixed to the inside of the sheet coating machine by bolts. The fixing plate is integrally provided with a hollow sleeve that cooperates with the support rod. Through the insertion and cooperation between the support rod and the hollow sleeve, not only can the two ends of the receiving roller be supported, but the tilt angle of the inner threaded sleeve can also be adjusted during the adjustment of the threaded adjustment rod.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-7 This utility model provides an automatic laminating machine with a tail roller, including a sheet laminating machine 1, in which two pressure rollers 4 are movably connected, and a sheet conveyor belt 2 is also provided on the side of one of the pressure rollers 4; An intermediate roller 7 is provided between the two pressure rollers 4, and an adjustment bracket 9 is provided at both ends of the intermediate roller 7. The adjustment bracket 9 on either side of the intermediate roller 7 is provided with two sets of mutually staggered arrangements.

[0021] By adopting the above technical solution, a receiving roller 71 is set between the two pressure rollers 4 to guide the film material passing under the pressure rollers 4, reduce the distance between the two pressure rollers 4, prevent the film material from getting stuck when passing through the gap between the two pressure rollers 4, thus ensuring the smoothness of the film material passing through the pressure rollers 4, and at the same time ensuring the smoothness of the sheet material during the conveying process, thereby improving the bonding quality between the film material and the sheet material.

[0022] Furthermore, the intermediate roller 7 is mainly composed of a receiving roller 71, and both ends of the receiving roller 71 are integrally provided with connecting shafts 72 that are movably connected to the adjusting bracket 9.

[0023] Furthermore, the adjusting bracket 9 includes a threaded adjusting rod 92 and an internally threaded sleeve 93 with threaded transmission engagement, wherein the end of the threaded adjusting rod 92 is provided with a support sleeve 91 that is movably connected to the connecting shaft 72.

[0024] More specifically, the side of the internal threaded sleeve 93 is integrally provided with a support rod 94, and a fixing plate 95 is sleeved on the outside of the support rod 94. The inner side of the fixed hole plate 95 is integrally provided with a hollow sleeve that cooperates with the support rod 94, and the hollow sleeve is rotatably engaged with the end of the support rod 94 away from the internal threaded sleeve 93.

[0025] By adopting the above technical solution, two intersecting adjusting brackets 9 are provided at both ends of the receiving roller 71. Rotating one of the threaded adjusting rods 92, the receiving roller 71 is pushed upward through the threaded engagement between the threaded adjusting rod 92 and the internal threaded sleeve 93. Furthermore, based on the two intersecting threaded adjusting rods 92, not only can the height of the receiving roller 71 be adjusted, but also the distance between the receiving roller 71 and any of the pressure rollers 4 can be adjusted. Precise adjustment can be made as needed, thereby improving the accuracy of adjusting the receiving roller 71.

[0026] Furthermore, guide rods 5 are arranged in a rectangular array above the pressure roller 4. The end of the film material passes over the guide rods 5 from above, and finally turns after passing over the end of the guide rods 5 until the film material moves to the bottom of the pressure roller 4 to guide the film material. Both ends of the guide rods 5 are movably connected to the sheet laminating machine 1. The sheet laminating machine 1 is also provided with a film feeding roller 6 for placing the film material at the end away from the sheet conveyor belt 2.

[0027] Furthermore, the end of the sheet conveyor belt 2 away from the sheet coating machine 1 is also provided with a drive assembly 3, and the drive assembly 3 and the end of the sheet conveyor belt 2 are driven together.

[0028] The drive assembly 3 is equipped with a drive motor, and the end of the drive motor is in transmission cooperation with the sheet conveyor belt 2. The drive motor can drive the sheet conveyor belt 2 to rotate, thereby moving the substrate on the sheet conveyor belt 2 to below the pressure roller 4.

[0029] More specifically, each of the aforementioned support bushings 91 is fitted with a silent bearing, and the inner ring of the silent bearing is also fitted with the connecting shaft 72 to reduce the noise when the receiving roller 71 rotates. Furthermore, a sealing ring is provided between the support bushing 91 and the connecting shaft 72 to further improve the noise reduction effect.

[0030] Furthermore, the sheet laminating machine 1 is also provided with a tail roller 8 at the end away from the sheet conveyor belt 2, which can quickly wind up excess film material and prevent excess film material from being wrapped into the end of the pressure roller 4.

[0031] The working principle of this utility model is as follows: In use, the rolled film material is first placed on the film feeding roller 6, and then one end of the film material is passed over the top of the guide rod 5, and after passing over the last guide rod 5, it passes under the pressure roller 4. At this time, the sheet conveyor belt 2 drives the substrate to move to the bottom of one of the pressure rollers 4. Through the squeezing of the pressure roller 4, the film material is bonded to the surface of the substrate. The bonded part gradually moves between the two pressure rollers 4. At this time, the receiving roller 71 located between the two pressure rollers 4 can not only support the substrate, but also prevent the sheet and film material from getting stuck during movement, ensuring the smoothness of the entire lamination process. Moreover, the height of the receiving roller 71 can be adjusted according to the thickness of the substrate or the actual situation. By rotating the threaded adjusting rod 92 on either side, the threaded engagement between the threaded adjusting rod 92 and the internal threaded sleeve 93 causes the support bushing 91 to push the receiving roller 71 upward, adjusting the position of the receiving roller 71, thereby improving the applicability. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
