The outer wall of the workbench 1 has two square holes 6. Movable blocks 7 are movably embedded in the inner walls of both square holes 6. Holes 8 are formed on the outer walls of both movable blocks 7. Movable blocks 8 are movably inserted between the inner walls of the two holes 8. A rotating shaft 2 9 is inserted, and an upper rubber roller 10 is fixedly sleeved on the outer wall of the rotating shaft 2 9. A drive motor 2 11 is set on one side of the outer wall of the rotating shaft 2 9. Two holes 3 12 are opened on the top of the worktable 1. Two hydraulic cylinders 13 are fixedly installed on the top of the worktable 1. Piston rods 14 are set at the output end of the two hydraulic cylinders 13, and the outer walls of the two piston rods 14 are inserted into the two holes 3 12. The bottom of the two piston rods 14 is fixedly connected to the top of the two movable blocks 7. A controller 15 is fixedly installed on one side of the outer wall of the worktable 1.

[0024] The effect achieved by the whole embodiment 1 is that, first of all, the two hydraulic cylinders 13 are controlled by the controller 15 to drive the two piston rods 14 to extend and retract, so that the two movable blocks 7 can be driven to move vertically, and finally the height of the upper rubber roller 10 can be adjusted, so that the device can adapt to plastic products of different sizes, improving the flexibility of the device. Secondly, after the height is adjusted, the driving motor one 5 and the driving motor two 11 are started, the driving motor one 5 drives the rotating shaft one 3 to rotate, so that the lower rubber roller 4 rotates, and at the same time the driving motor two 11 drives the rotating shaft two 9 to rotate, so that the upper rubber roller 10 rotates. The direction of operation of the upper rubber roller 10 and the lower rubber roller 4 is opposite, which can simultaneously coat the plastic product on both sides. At the same time of coating, the plastic product can be transmitted backward following the rotation of the rubber roller.

[0025] As shown in embodiment 2, Figures 1-4 The inner wall of the workbench 1 is fixedly installed with a glue groove 16 at the bottom, the inner surface wall of the glue groove 16 is fixedly installed with a liquid level sensor one 17, the inner surface wall of the workbench 1 is fixedly installed with a lower scraper 18, the top of the workbench 1 is fixedly installed with a glue box 19, the inner surface wall of the glue box 19 is fixedly installed with a liquid level sensor two 20, the bottom of the glue box 19 is fixedly communicated with a glue outlet pipe 21, the outer surface wall of the glue outlet pipe 21 is provided with an electric valve 22, the opposite side of the two movable blocks 7 is fixedly installed with an upper scraper 23, and the top of the workbench 1 is provided with two square grooves 24, and the inner surface wall of the two square grooves 24 is provided with a set of transmission rollers 25.

[0026] The effect achieved by the whole embodiment 2 is that, when the device is in normal use, first of all, the opening of the electric valve 22 can make the glue in the glue box 19 flow out through the glue outlet pipe 21. Since the glue outlet pipe 21 is located above the upper rubber roller 10, the glue finally falls on the surface of the upper rubber roller 10. Secondly, the upper scraper 23 evenly scrapes the glue on the surface of the upper rubber roller 10, and at the same time the lower rubber roller 4 directly sticks the glue in the glue groove 16 on the surface by rotating, and then the lower scraper 18 evenly scrapes it, which can ensure that the glue coating on the plastic product is more uniform. Secondly, the liquid level sensor one 17 and the liquid level sensor two 20 can detect the remaining amount of glue in the glue groove 16 and the glue box 19 in real time, so that the staff can be notified to supplement and add when the remaining amount is too small. Finally, the transmission rollers 25 assist the movement of the plastic product.

[0027] Among them, the driving motor one 5, the driving motor two 11, the hydraulic cylinder 13, the controller 15, the liquid level sensor one 17, the liquid level sensor two 20 and the electric valve 22 are all prior art, and their components and use principles are all public technology, which will not be explained here.

[0028] Working principle: first, in the normal use of the device, the plastic products are placed on the transmission roller 25 on one side, at this time, through the controller 15 control drive motor one 5 and drive motor two 11 operation, drive motor one 5 operation can drive the rotation of the shaft one 3, thus driving the lower rubber roller 4 rotation, at the same time, the lower rubber roller 4 is just below the glue groove 16, the lower rubber roller 4 will pass through the glue groove 16 when rotating, the glue will stick to the surface of the lower rubber roller 4, secondly, the lower scraper 18 is located on one side of the lower rubber roller 4, and is attached to its surface, the lower rubber roller 4 continues to rotate through the lower scraper 18, the lower scraper 18 can tightly adhere to the surface of the lower rubber roller 4, and the glue on the lower rubber roller 4 is scraped flat and evenly, which helps to ensure that the glue is evenly distributed on the surface of the plastic product, avoiding the accumulation or lack of glue, at the same time, the drive motor two 11 operation drives the rotation of the shaft two 9, thus making the upper rubber roller 10 rotate, and through the controller 15 opens the electric valve 22, so that the glue in the glue box 19 can flow out through the glue outlet pipe 21, and finally flows to the surface of the upper rubber roller 10, the electric valve 22 here adopts a screw valve, which is prior art, and the rotation speed, forward and reverse time of the screw can be accurately controlled through the controller 15, so as to accurately control the output amount of glue, realize trace and accurate gluing, and the screw valve can well output the fluid with medium and high viscosity. At the same time, the upper scraper 23 is located on one side of the upper rubber roller 10 and is attached to its surface, which plays the same role as the lower scraper 18 through the rotation of the upper rubber roller 10. Secondly, through the controller 15 control two hydraulic cylinders 13 operation, drive two piston rods 14 extension and retraction, finally drive two movable blocks 7 vertical movement, finally can drive the upper rubber roller 10 height adjustment, adjustable glue roller spacing, can according to the material characteristics, thickness and the demand of gluing process, flexible adjustment of gluing amount, ensure the best gluing effect, at the same time, the upper scraper 23 is fixedly connected with the two movable blocks 7, which can move with the height adjustment of the upper rubber roller 10, ensuring that the upper scraper 23 is on one side of the surface of the upper rubber roller 10. Secondly, the inner wall of the glue groove 16 is fixedly installed with liquid level sensor one 17, and the inner wall of the glue box 19 is fixedly installed with liquid level sensor one 17. The liquid level sensor one 17 and the liquid level sensor two 20 can detect the amount of glue in the glue groove 16 and the glue box 19 in real time. When the amount of glue is too small, the staff can be notified in time to supplement and add. Finally, the plastic products are rotated in opposite directions through the two glue rollers to be glued. At the same time, the plastic products are transported backward with the rotation, and the other set of transmission rollers 25 makes the plastic products with glue move more smoothly.
