Description

Technical Field

[0001] This utility model relates to the field of calendering mechanism technology, and in particular to a calendering mechanism for a calendering machine. Background Technology

[0002] A calender consists of two or more rollers arranged according to the heating method. It can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite films, graphite sheets, microwave absorbing materials, shielding materials, magnetic materials, and non-ferrous metals. Hot pressing is further divided into water heating, electric heating, oil heating, and electromagnetic heating. Both types of machines press and stretch materials such as rubber, silicone rubber, silicone rubber, phase change materials, PTFE, or plastics into sheets of a certain thickness and surface shape at a specific temperature. They can also be used to coat fiberglass or steel wire fabrics with adhesive.

[0003] During the calendering process of PVC automotive wrap film, raw materials easily adhere to the surface of the rollers. Because this process requires simultaneous inkjet printing, both plastic material and ink residue often remain on the roller surface. Currently, after the calendering process, operators generally use tools such as scrapers or cloths to clean the roller surface to ensure that subsequent production is not affected by residues.

[0004] Although existing technologies have developed some cleaning mechanisms for calenders, scraper wear remains a significant problem during long-term use. Furthermore, because different calendered materials require different scraper types, frequent scraper replacements are often necessary during production. Current cleaning mechanisms require scraper replacement to be performed while the machine is stopped, which not only increases operational complexity but also reduces the calender's production efficiency. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a calendering mechanism for a calendering machine. Through the coordinated use of components such as cleaning and replacement, it solves the problem of requiring machine shutdown for scraper replacement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A calendering mechanism for a calendering machine includes a base, on which symmetrical support plates are mounted, and a pressure roller is rotatably connected between the two support plates. A calendering mechanism for driving the pressure roller is mounted on the base. The calendering mechanism also includes: a cleaning component mounted on the base for cleaning impurities on the pressure roller; and a replacement component mounted on the cleaning component for replacing the cleaning component without stopping the machine.

[0008] Preferably, the cleaning component includes connecting plates symmetrically mounted on the base and the support plate, a rotating rod rotatably connected between the connecting plates, a rotating cylinder fixedly connected to the outside of the rotating rod, symmetrical slots on the rotating cylinder, and connecting rods detachably connected inside both slots. A scraper is fixedly connected to the outside of the connecting rod, and the scraper is used to remove impurities from the outside of the pressure roller.

[0009] Preferably, limit holes are evenly provided on one of the connecting plates, and the rotating rod passes through one of the connecting plates and is fixedly connected to a turntable, the turntable being rotatably connected to the connecting plate.

[0010] Preferably, a connecting spring is fixedly connected to the turntable, and a positioning pin is fixedly connected to the outside of the connecting spring. The positioning pin passes through the turntable and engages with the limiting hole.

[0011] Preferably, the replacement component includes a protrusion fixedly installed inside the connecting rod, and the protrusion has symmetrically formed locking holes on its exterior.

[0012] Preferably, a limiting plate is fixedly installed inside the slot, and limiting grooves are symmetrically opened on the limiting plate. A lead screw is symmetrically rotatably connected inside the rotating cylinder. A slider is threaded to the outside of both lead screws. A locking post is fixedly connected to both sliders through the limiting groove. The diameter of the locking post is the same as the diameter of the locking hole. The slider is slidably connected to the limiting groove.

[0013] Preferably, the ends of the two lead screws away from the rotating drum are respectively fixedly connected to a round nut and a tripod nut through the turntable, and both lead screws are rotatably connected to the turntable.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Example 1: Please refer to Figure 1 - Figure 6 A calendering mechanism for a calendering machine includes a base 1, on which symmetrically mounted bearing plates 2 are mounted. The bearing plates 2 are made of high-quality carbon steel No. 45 and are heat-treated to improve their overall mechanical properties. A pressure roller 5 is rotatably connected between the two bearing plates 2. A calendering mechanism 3 for driving the pressure roller 5 is mounted on the base 1. The calendering mechanism 3 is prior art and will not be described in detail here. The machine also includes: a cleaning component 4 mounted on the base 1, which is used to clean impurities on the pressure roller 5; and a replacement component 6 mounted on the cleaning component 4, which is used to replace the cleaning component 4 without stopping the machine.

[0027] For further details, please refer to Figure 4 The cleaning component 4 includes connecting plates 7 symmetrically mounted on the base 1 and the support plate 2. The connecting plates 7 are made of 304 stainless steel, which is both corrosion-resistant and rigid. A rotating rod 9 is rotatably connected between the connecting plates 7. A rotating cylinder 8 is fixedly connected to the outside of the rotating rod 9. The main body of the rotating cylinder 8 is made of aluminum alloy. The rotating cylinder 8 has symmetrical slots 14. Both slots 14 are detachably connected to connecting rods 16. The connecting rods 16 are made of engineering plastic POM, which is both self-lubricating and impact-resistant. It can effectively buffer the impact force when the scraper 17 contacts the pressure roller 5. The scraper 17 is fixedly connected to the outside of the connecting rod 16. The scraper 17 is used to remove external impurities from the pressure roller 5. The scraper 17 is made of special polyurethane rubber, and the surface is sanded to form a micron-level serrated structure. It can efficiently peel off PVC material residue and ink traces, and avoid scratching the chrome-plated surface of the pressure roller 5. When the pressure roller 5 rotates, the rotating cylinder 8 rotates synchronously through friction. The scraper 17 contacts the surface of the pressure roller 5 in a tangential direction and uses centrifugal force to help throw the impurities away from the collection tank.

[0028] For further details, please refer to Figure 5 One of the connecting plates 7 has evenly spaced limit holes 11. A rotating rod 9 passes through one of the connecting plates 7 and is fixedly connected to a turntable 10. The turntable 10 is made of alloy steel and is rotatably connected to the connecting plate 7. A connecting spring 13 is fixedly connected to the turntable 10. A positioning pin 12 is fixedly connected to the outside of the connecting spring 13. The positioning pin 12 passes through the turntable 10 and engages with the limit holes 11. The positioning pin 12 can be used to position the turntable 10, thereby positioning the rotating cylinder 8.

[0029] Example 2: Based on Example 1, according to Figure 2 - Figure 6 As shown, it is worth noting that the replacement component 6 includes a protrusion 18 fixedly installed inside the connecting rod 16. The protrusion 18 is made of zinc alloy die casting and has a hard chrome plated surface to improve wear resistance. The protrusion 18 has symmetrically opened locking holes 19 on its exterior. A limit plate 15 is fixedly installed inside the locking groove 14. A limit groove 23 is symmetrically opened on the limit plate 15. A lead screw 20 is symmetrically rotatably connected inside the rotating drum 8. The lead screw 20 is a high-precision trapezoidal lead screw. Both lead screws 20 are threadedly connected to sliders 21 on their exterior. The sliders 21 are made of polytetrafluoroethylene-filled nylon material with a friction coefficient as low as 0.05, which can achieve smooth displacement under the drive of the lead screw 20. Both sliders 21 are fixedly connected to locking posts 22 through the limit groove 23. The diameter of the locking post 22 is the same as the diameter of the locking hole 19. The sliders 21 are slidably connected to the limit groove 23.

[0030] Please see Figure 6It is worth noting that the ends of the two lead screws 20 away from the rotating drum 8 are respectively fixedly connected to the turntable 10 with a round nut 24 and a tripod nut 25. The round nut 24 and the tripod nut 25 are used to distinguish between the old and new scrapers 17. Both lead screws 20 are rotatably connected to the turntable 10. When the scraper 17 needs to be replaced, the operator can rotate the tripod nut 25 to drive the lead screw 20 to rotate while the equipment is running, so that the slider 21 retracts along the limit groove 23 and the locking post 22 disengages from the locking hole 19. The old connecting rod 16 assembly can be quickly pulled out and the new assembly can be inserted. Then, the tripod nut 25 is rotated in the opposite direction to lock it. The replacement time is no more than 30 seconds.

[0031] The working principle of this solution is as follows:

[0032] First, pull the positioning pin 12 out of the limiting hole 11, rotate the turntable 10, and drive the rotating drum 8 to rotate through the rotating rod 9 inside the turntable 10, thereby driving the connecting rod 16 and the scraper 17 to rotate, so that the new scraper 17 re-contacts the surface of the pressure roller 5. Then, insert the positioning pin 12 into the limiting hole 11.

[0033] Next, by rotating the tripod cap 25, the lead screw 20 is rotated, causing the slider 21 to retract along the limiting groove 23, and the locking post 22 to disengage from the locking hole 19. This allows the old connecting rod 16 and scraper 17 to be quickly pulled out and the new scraper 17 to be inserted.

[0034] Finally, rotate the tripod cap 25 in the opposite direction to lock it in place, and the scraper blade 17 can be replaced.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
