Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing, specifically a calendering device for processing plastic sheets. Background Technology

[0002] In the processing of plastic sheets, in order to make it easier to uniformly stretch the heated and plasticized thermoplastic into sheets or films of appropriate thickness for subsequent processing or sales, a calendering device is required. In use, existing calendering equipment typically employs two pressure rollers working together to place uncalendered plastic sheets between the rollers. The plastic is then calendered to a suitable thickness through the squeezing and rotation of the two rollers. However, after the existing calendering equipment calenders the plastic into sheets, the high temperature remaining on the plastic sheets makes it easy for workers to get burned when they come into contact with the plastic sheets. In addition, after the pressure rollers calender the plastic sheets, their surfaces are often contaminated with impurities. If these impurities are not removed, they can also affect the subsequent calendering of the equipment. Therefore, a calendering device for processing plastic sheets is proposed to address the above problems. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A calendering device for processing plastic sheets according to this utility model includes a base. A first pressure roller is rotatably connected to the inner side of the base. A first gear is fixedly connected to one end of the first pressure roller. A second gear meshes with the side of the first gear that is close to each other. A motor is fixedly connected to the outer side of the base. The output end of the motor is fixedly connected to the second gear. A second pressure roller is rotatably connected to the inner side of the base. A cooling fan is fixedly connected to the outer side of the base. The cooling fan works in conjunction with the second pressure roller. A pulley is fixedly connected to one side of the second pressure roller and one side of the first gear. A pulley is rotatably connected to the outer side of the pulley. The device includes a belt conveyor. This step involves setting up a first pressure roller, a second pressure roller, and a cooling fan. Plastic is fed from one side of the first pressure roller into the space between them. A motor drives a second gear to rotate, which in turn drives the first gear and the first pressure roller to rotate. This causes the first pressure roller to extrude the plastic into a sheet. The plastic sheet is then guided between the second pressure rollers. A cooling fan cools the air and blows it into the groove in the center of the second pressure roller to further cool it. The second pressure roller then contacts the calendered plastic sheet, further cooling it. This prevents the plastic sheet from overheating and potentially burning workers, thus improving the stability of the device.

[0005] Preferably, multiple scraper frames are fixedly connected to the outer side of the base, and brushes are fixedly connected to the upper side of the scraper frames. The first and second pressure rollers are used in conjunction with the scraper frames and brushes. This step, by setting up the scraper frames and brushes, allows the first and second pressure rollers to rotate to contact one edge of the scraper frame and the brush after calendering the plastic sheet. This allows plastic impurities that adhere to the sheet during calendering to be scraped off and fall into the inner side of the scraper frames, keeping the first and second pressure rollers clean. This makes subsequent calendering of the device more stable and improves the stability of the device's operation.

[0006] Preferably, a hydraulic cylinder is fixedly connected to the outer side of the base, a movable frame is fixedly connected to the output end of the hydraulic cylinder, and a push plate is fixedly connected to the outer side of the movable frame. This step, by setting up a hydraulic cylinder, a movable frame, and a push plate, allows the movable frame to move when a large amount of impurities accumulate inside the scraping frame. The movable frame then moves the push plate, enabling one side of the push plate to push the impurities out from inside the scraping frame, facilitating subsequent collection of impurities by the user and improving the convenience of cleaning the device.

[0007] Preferably, a heat-conducting sheet is fixedly connected to the inner side of the second pressure roller, and an atomizing nozzle is fixedly connected to one side of the base. This step, by setting the heat-conducting sheet and the atomizing nozzle, allows the atomizing nozzle to be connected to an outer pipe that can deliver water before use, so that water can be sprayed out from the atomizing nozzle. The cooling fan drives the cold air and water to contact the second pressure roller and the heat-conducting sheet, thereby facilitating further cooling of the second pressure roller, making the cooling effect of the second pressure roller on the plastic sheet better, and improving the stability of the device.

[0008] Preferably, a limiting rod is fixedly connected to one end of the moving frame, and a receiving groove is provided on the inner side of the base. The limiting rod and the receiving groove are slidably connected. This step, by setting the limiting rod and the receiving groove, ensures that when the moving frame moves, it will drive the limiting rod to move. The receiving groove restricts the movement trajectory of the limiting rod, thereby limiting the other end of the moving frame away from the hydraulic cylinder. This makes the movement of the moving frame more stable and improves the stability of the device.

[0009] Preferably, a mounting plate is fixedly connected to the outer side of the base, and the surface of the mounting plate is provided with a mounting groove. This step, by setting up the mounting plate and the mounting groove, allows the device to be installed and fixed directly by screwing bolts into the mounting groove and the mounting location, thus improving the convenience of device installation.

[0010] The advantages of this utility model are: 1. This utility model, by setting up a first pressure roller, a second pressure roller, and a cooling fan, feeds plastic from one side of the first pressure roller into the space between the first pressure rollers. A motor drives a second gear to rotate, which in turn drives the first gear and the first pressure roller to rotate, causing the first pressure roller to extrude the plastic into a sheet. The plastic sheet is then guided between the second pressure rollers. The cooling fan cools the air and blows it into the empty groove in the center of the second pressure roller to cool the second pressure roller. The second pressure roller comes into contact with the calendered plastic sheet, thereby cooling the plastic sheet. This prevents the plastic sheet from overheating and causing burns to workers, thus improving the stability of the device. 2. By setting up a scraper frame and a brush, after the first and second pressure rollers calender the plastic sheet, they rotate to contact one edge of the scraper frame and the brush. This allows plastic impurities that adhere to the plastic sheet during calendering to be scraped off and fall into the inner side of the scraper frame, keeping the first and second pressure rollers clean. This makes subsequent calendering more stable and improves the stability of the device. Attached Figure Description

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 scope of protection of the present utility model.

[0015] Specific implementation examples are given below.

[0016] Please see Figures 1 to 5 As shown, a calendering device for processing plastic sheets includes a base 1. A first pressure roller 2 is rotatably connected to the inner side of the base 1. A first gear 3 is fixedly connected to one end of the first pressure roller 2. A second gear 4 meshes with the first gear 3 on its adjacent side. A motor 5 is fixedly connected to the outer side of the base 1. The output end of the motor 5 is fixedly connected to the second gear 4. A second pressure roller 6 is rotatably connected to the inner side of the base 1. A cooling fan 7 is fixedly connected to the outer side of the base 1. The cooling fan 7 works in conjunction with the second pressure roller 6. Pulleys 8 are fixedly connected to one side of the second pressure roller 6 and one side of the first gear 3. A belt 9 is rotatably connected to the outer side of the pulleys 8. This step involves setting... The first pressure roller 2, the second pressure roller 6, and the cooling fan 7 feed plastic from one side of the first pressure roller 2 into the space between the first pressure rollers 2. The motor 5 drives the second gear 4 to rotate, which in turn drives the first gear 3 and the first pressure roller 2 to rotate, causing the first pressure roller 2 to extrude the plastic into a sheet. The plastic sheet is then guided to the space between the second pressure rollers 6. The cooling fan 7 cools the air and blows it into the empty groove in the center of the second pressure roller 6 to cool the second pressure roller 6. The second pressure roller 6 comes into contact with the calendered plastic sheet, thereby cooling the plastic sheet and preventing it from overheating and causing burns to workers, thus improving the stability of the device.

[0017] Furthermore, such as Figures 1 to 4 As shown, multiple scraper frames 10 are fixedly connected to the outer side of the base 1, and brushes 11 are fixedly connected to the upper side of the scraper frames 10. The first pressure roller 2 and the second pressure roller 6 are used in conjunction with the scraper frames 10 and the brushes 11. This step, by setting the scraper frames 10 and the brushes 11, allows the first pressure roller 2 and the second pressure roller 6 to rotate to contact one edge of the scraper frame 10 and the brushes 11 after calendering the plastic sheet. This allows plastic impurities that adhere during calendering to be scraped off and fall to the inside of the scraper frame 10, keeping the first pressure roller 2 and the second pressure roller 6 clean. This makes the subsequent calendering of the device more stable and improves the stability of the device in use.

[0018] Furthermore, such as Figure 1 and Figure 5As shown, a hydraulic cylinder 12 is fixedly connected to the outer side of the base 1, a movable frame 13 is fixedly connected to the output end of the hydraulic cylinder 12, and a push plate 14 is fixedly connected to the outer side of the movable frame 13. In this step, by setting up the hydraulic cylinder 12, the movable frame 13 and the push plate 14, after a large amount of impurities accumulate inside the scraper frame 10, the hydraulic cylinder 12 can drive the movable frame 13 to move, and the movable frame 13 can drive the push plate 14 to move, so that the push plate 14 on one side can push the impurities out from the inside of the scraper frame 10, so that the user can collect the impurities later, which improves the convenience of cleaning the device.

[0019] Furthermore, such as Figure 1 As shown, a heat-conducting plate 15 is fixedly connected to the inner side of the second pressure roller 6, and an atomizing nozzle 16 is fixedly connected to one side of the base 1. This step, by setting the heat-conducting plate 15 and the atomizing nozzle 16, allows the atomizing nozzle 16 to be connected to an outer pipe that can deliver water before use, so that water can be sprayed out from the atomizing nozzle 16. The cooling fan 7 drives the cold air and water to contact the second pressure roller 6 and the heat-conducting plate 15, thereby facilitating further cooling of the second pressure roller 6, making the cooling effect of the second pressure roller 6 on the plastic sheet better, and improving the stability of the device.

[0020] Furthermore, such as Figure 1 and Figure 2 As shown, a limiting rod 17 is fixedly connected to one end of the moving frame 13, and a receiving groove 18 is provided on the inner side of the base 1. The limiting rod 17 and the receiving groove 18 are slidably connected. This step, by setting the limiting rod 17 and the receiving groove 18, ensures that when the moving frame 13 moves, it will drive the limiting rod 17 to move. The receiving groove 18 restricts the movement trajectory of the limiting rod 17, thereby limiting the other end of the moving frame 13 away from the hydraulic cylinder 12. This makes the movement of the moving frame 13 more stable and improves the stability of the device.

[0021] Furthermore, such as Figure 1 As shown, a mounting plate 19 is fixedly connected to the outer side of the base 1, and a mounting groove 20 is provided on the surface of the mounting plate 19. By setting the mounting plate 19 and the mounting groove 20, the device can be installed and fixed by directly screwing the bolts into the mounting groove 20 and the mounting location, which improves the convenience of device installation.

[0022] Working principle: Before use, the atomizing nozzle 16 can be connected to an external pipe that can deliver water, allowing water to be sprayed from the atomizing nozzle 16. The cooling fan 7 drives the cold air and water to contact the second pressure roller 6 and the heat-conducting plate 15, facilitating further cooling of the second pressure roller 6. Plastic is fed from one side of the first pressure roller 2 between the first pressure rollers 2. The motor 5 drives the second gear 4 to rotate, which in turn drives the first gear 3 and the first pressure roller 2 to rotate, causing the first pressure roller 2 to extrude the plastic into a sheet. The plastic sheet is then guided to the second pressure roller 2. Between the rollers 6, the first gear 3 drives the outer pulley 8 to rotate, which in turn drives the belt 9 to rotate. The belt 9 then drives the outer pulley 8 of the second pressure roller 6 to rotate, thus enabling the second pressure roller 6 to rotate and convey the plastic sheet. During conveying, the cooled second pressure roller 6 comes into contact with the plastic sheet, further cooling it. As the first pressure roller 2 and the second pressure roller 6 rotate, the scraper frame 10 and the brush 11 continuously scrape and clean the surfaces of the first pressure roller 2 and the second pressure roller 6 to remove excess impurities.
