[0026] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the adjustment component 11 includes a mounting groove 111, which is opened on the top side wall of the frame 2, and a cylinder 112 is fixed inside the mounting groove 111. A through hole 113 is opened on the top side wall of the frame 2, and the output end of the cylinder 112 is located inside the through hole 113. The output end of the cylinder 112 is fixed to the top side wall of the support frame b7, and the top side wall of the support frame b7 is fixed with two symmetrically distributed guide rods 114, and the guide rods 114 are slidably penetrated with the side wall of one side of the frame 2, and two symmetrically distributed hollow tubes 115 are fixed to the top side wall of the frame 2, and the guide rods 114 are slidably connected with the inside of the hollow tubes 115. Through the setting of the adjustment component 11, the distance between the roller body b9 and the roller body a5 can be adjusted according to actual needs, so that it can be suitable for different plastic product processing work, further improving the scope of application of the device, and the adjustment operation is simple and reliable, and can effectively improve the pressing accuracy of the plastic, has high practical value, and is convenient for staff to maintain and maintain the roller body a5 and the roller body b9.

[0027] Further as Figure 2 and Figure 3As shown, it is worth explaining in detail that two symmetrically distributed guide grooves 12 are provided on the outer side wall of the hollow tube 115, and a guide block 13 is fixed at one end of the guide rod 114, and the guide block 13 is slidably connected to the inside of the guide groove 12. Through the setting of the guide block 13 and the guide groove 12, not only can the guide rod 114 be guided and limited, but also the stability of the guide rod 114 during movement can be greatly improved, avoiding the shaking of the guide rod 114 during movement, and further improving the smoothness of the support frame b7 during movement.

[0028] This solution has the following working process: when the plastic product needs to be calendered, the plastic product is first placed between the roller a5 and the roller b9, and the support frame b7 and the roller b9 are synchronously moved downward by the drive of the cylinder 112 until the outer surface of the roller b9 is in a fit state with the plastic product, and the servo motor a6 and the servo motor b10 are driven to ensure that the servo motor a6 and the servo motor b10 are in opposite directions to drive the roller a5 and the roller b9 to operate, and the roller a5 and the roller b9 are driven by the roller a5 and the roller b9. b9 rotates in the opposite direction to complete the calendering process of the plastic product. When the residue on the surface of the roller a5 needs to be cleaned, the rotating wheel 143 is rotated to make the rotating rod 141 rotate synchronously, driving the scraper 142 to rotate synchronously until one side of the scraper 142 is in contact with the outer surface of the roller a5, and the rotation of the roller a5 and the scraper 142 generate contact friction, so that the residue on the outer surface of the roller a5 is scraped off, and the scraped residue falls into the collection box 16 for collection and storage.

[0029] According to the above working process, it can be known that: through the setting of the adjustment component 11, the distance between the roller body b9 and the roller body a5 can be adjusted according to actual needs, so that it can be suitable for different plastic product processing work, further improving the application range of the device, and the adjustment operation is simple and reliable, and can effectively improve the pressing accuracy of the plastic, with high practical value, convenient for staff to maintain and maintain the roller body a5 and the roller body b9, and through the setting of the cleaning component 14, the residues generated during the calendering process at the roller body a5 can be cleaned, thereby greatly improving the calendering effect of the plastic product calendering process, and preventing the residues on the surface of the roller body a5 from affecting the quality of the plastic product after calendering, and the operation is simple, the structural reliability is high, the angle and direction of the scraper 142 can be adjusted according to the needs, the operation is easy to use, and the practicability is strong.

[0030] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth explaining in detail that a cleaning component 14 adapted to the roller body a5 is provided on one side of the support frame a3, and the cleaning component 14 comprises a rotating rod 141, which is rotatably connected to the side wall of one side of the support frame a3, and a scraper 142 is tightly sleeved on the outer surface of the rotating rod 141, and the scraper 142 is located directly below the roller body a5, and a rotating wheel 143 is fixed at one end of the rotating rod 141, and a ratchet 144 is tightly sleeved on the outer surface of the rotating rod 141, and a pawl 145 is rotatably connected to the side wall of one side of the support frame a3, and the pawl 145 is meshed with the ratchet 144. Through the setting of the cleaning component 14, the residue generated during the calendering process of the roller body a5 can be cleaned, thereby greatly improving the calendering effect of the calendering process of the plastic product, and preventing the residue on the surface of the roller body a5 from affecting the quality of the plastic product after calendering. In addition, the operation is simple and the structural reliability is high. The angle and direction of the scraper 142 can be adjusted according to the demand, and the operation is easy to use and has strong practicality.

[0031] Further as Figure 3 and Figure 5 As shown, it is worth explaining in detail that both sides of the scraper 142 are chamfered and inclined, a through groove 15 is jointly provided between the frame 1 and the support frame a3, and a collecting box 16 is slidably connected to the inner side wall of the frame 1. The collecting box 16 is located directly below the through groove 15. Through the arrangement of the collecting box 16 and the through groove 15, it is ensured that the collecting box 16 can receive the residues scraped off the surface of the roller a5, and prevent the scraped impurities from falling into the surrounding non-working areas, which not only facilitates the collection of the staff, but also further reduces the labor intensity of the staff.

[0032] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a slide groove 17 is opened on the side wall of one side of the frame 1, and the collection box 16 is slidably connected to the inside of the slide groove 17. By sliding the collection box 16 in the slide groove 17, it can not only guide the collection box 16, but also avoid the collection box 16 from being displaced when being pulled or pushed.

[0033] In summary: through the setting of the guide block 13 and the guide groove 12, not only can it play a guiding and limiting role on the guide rod 114, but also can greatly improve the stability of the guide rod 114 during movement, avoid shaking when the guide rod 114 moves, and further improve the smoothness of the support frame b7 during movement. Through the setting of the collecting box 16 and the through groove 15, it is ensured that the collecting box 16 can receive the residues scraped off the surface of the roller a5, and prevent the scraped impurities from falling into the surrounding non-working area, which not only facilitates the collection of the staff, but also further reduces the labor intensity of the staff. Through the sliding of the collecting box 16 in the slide groove 17, it can not only guide the collecting box 16, but also avoid the displacement of the collecting box 16 when it is pulled and pushed.

[0034] The servo motor a6, servo motor b10 and cylinder 112 can all be purchased on the market. The servo motor a6, servo motor b10 and cylinder 112 are all equipped with power supplies. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
