[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment: an upper pressure roller assembly device for producing plastic products, including a machine base 1, a support frame 21, and a stamping assembly. An extension frame 4 is fixedly connected to the outside of the machine base 1. The stamping assembly is located on the top of the machine base 1. The support frame 21 is fixedly connected to the top of the machine base 1. A sliding block 22 is located inside the support frame 21. A locking block 27 is engaged inside the sliding block 22 and slidably connected to the inside of the support frame 21. An optical shaft 23 is fixedly connected to the inner side of the sliding block 22. A limiting disk 24 is fixedly connected to the outside of the optical shaft 23. An upper pressure roller body 25 is located inside the limiting disk 24. The upper pressure roller body 25 is rotatably connected to the outside of the optical shaft 23 and is engaged inside the sliding block 22 by the locking block 27, thus fixing the upper pressure roller body 25. The interior of block 22 allows for the disassembly and assembly of the upper pressure roller body 25 without the need for specific tools. The stamping assembly performs stamping through the stamping die 37 inside the upper punch plate 33, and ejects the formed product from the stamping hole through the stamping die 37 inside the lower punch plate 35, thus completing the stamping process and improving stamping efficiency. The support frame 21 has a groove at the corresponding position of the sliding block 22, and the sliding block 22 is set in the groove. The groove limits the upper pressure roller body 25 during installation, ensuring the stability of the installation. The sliding block 22 has a groove at the corresponding position of the locking block 27, and the locking block 27 engages in the groove, allowing for the fixing and unfixing of the upper pressure roller body 25, thus improving the ease of disassembly and assembly of the upper pressure roller body 25.
[0021] Please see Figure 2 - Figure 3In this embodiment, a limiting frame 26 is fixedly connected to the outer side of the upright frame 21, a locking block 27 is slidably connected to the inside of the limiting frame 26, a limiting shaft 28 is fixedly connected to the inside of the locking block 27, the limiting shaft 28 is slidably connected to the inside of the limiting frame 26, a lever 210 is fixedly connected to the outside of the limiting shaft 28, and a first spring 29 is fixedly connected between the locking block 27 and the limiting frame 26, so that it does not require the use of specific tools for disassembly and assembly, and improves the maintenance efficiency of the upper pressure roller body 25, improves the production efficiency of the rotary press, and improves its practicality.
[0022] Please see Figure 1 , Figure 4 - Figure 5 In this embodiment, the stamping assembly includes a motor 31, which is fixedly connected to the bottom of the machine base 1. A rotating shaft 32 is fixedly connected to the output end of the machine base 1 and rotatably connected inside the machine base 1. An upper punch plate 33 is fixedly connected to the outside of the rotating shaft 32, a middle die plate 34 is fixedly connected to the outside of the rotating shaft 32, and a lower punch plate 35 is fixedly connected to the outside of the rotating shaft 32. A stamping die 37 is disposed inside the upper punch plate 33 and inside the lower punch plate 35. A limiting plate 38 is fixedly connected to the outside of the stamping die 37. A second spring 39 is fixedly connected between the limiting plate 38 and the upper punch plate 33, and between the limiting plate 38 and the lower punch plate 35. A fixed shaft 310 is fixedly connected inside the stamping die 37, and a pressing wheel 311 is rotatably connected to the outside of the fixed shaft 310. A pressing block 36 is fixedly connected to the top of the machine base 1. The stamping die 37 is equipped with a pressure roller 311 at one end, which cooperates with the upper pressure roller body 25 to ensure the stamping effect of the stamping die 37 on the product. The second spring 39 drives it to reset, so as to ensure the normal operation of stamping and improve the stamping efficiency. There are two sets of stamping dies 37, which are respectively distributed inside the upper punch plate 33 and the lower punch plate 35. The stamping is performed by the stamping die 37 inside the upper punch plate 33, and the formed product in the stamping hole is ejected by the stamping die 37 inside the lower punch plate 35, so as to complete the stamping and improve the stamping efficiency. The upper punch plate 33 and the lower punch plate 35 are respectively provided with grooves at corresponding positions of the limiting plate 38. The limiting plate 38 slides inside the upper punch plate 33 and the lower punch plate 35, so as to be reset by the second spring 39, so as to ensure the normal operation of stamping and improve the stability.
[0023] During operation, raw material is injected into the punching holes on the middle die 34. The motor 31 is started, causing the upper punch plate 33, middle die 34, and lower punch plate 35 to rotate via the rotating shaft 32. When the pressure roller 311 of the upper punch plate 33 is pressed by the upper pressure roller body 25, it punches and forms the raw material in the punching hole. The limiting plates 24 on both sides of the upper pressure roller body 25 limit its movement. Then, the pressure roller 311 of the stamping die 37 is pressed by the pressure block 36, pushing the formed product out of the punching hole, completing the stamping process. The second spring 39 drives it to reset, ensuring normal stamping operation and guaranteeing the stamping effect of the upper punch plate 33. When the upper pressure roller body 25 needs to be disassembled for maintenance, the levers 210 on both sides are pulled outwards, causing it to rotate via the limiting shaft 28. The locking block 27 moves away from the corresponding groove of the sliding block 22, thereby releasing the limiting position of the sliding block 22 and allowing the upper pressure roller body 25 to be disassembled. This eliminates the need for specific tools for disassembly and assembly, and improves the maintenance efficiency of the upper pressure roller body 25. When installing the repaired upper pressure roller body 25, the sliding blocks 22 on both sides are aligned with the corresponding grooves of the support frame 21, and the sliding blocks 22 are pressed down. When the sliding blocks 22 contact the angle of the locking block 27, the locking block 27 is moved outward, compressing the first spring 29. When the sliding block 22 slides to the deepest part of the groove of the support frame 21, the elasticity of the first spring 29 causes the locking block 27 to move, causing the locking block 27 to engage in the groove of the sliding block 22, thus fixing the upper pressure roller body 25 and completing the installation of the repaired upper pressure roller body 25.
[0024] Through the above steps, the locking block 27 is engaged inside the sliding block 22, allowing the upper pressure roller body 25 to be disassembled and assembled without the need for specific tools. This improves the maintenance efficiency of the upper pressure roller body 25 and solves the problem that when the upper pressure roller needs to be disassembled and repaired, not only are specific tools required, but the maintenance of the upper pressure roller is also time-consuming and laborious.
