Description

Technical Field

[0001] This utility model belongs to the field of calendering traction technology, and in particular relates to a traction fixing structure for calendering processing. Background Technology

[0002] A calender is an industrial device that applies pressure to materials through rotating rollers to achieve material stretching, shaping, or surface treatment. Its core feature is the use of two or more parallel rollers to continuously process materials such as metals, rubber, plastics, and paper by adjusting the pressure, temperature, and rotation speed between the rollers.

[0003] Currently, when materials enter the pressure roller, they are deformed by pressure. Materials that do not enter the pressure roller are prone to skew, and the portion of the material that does not enter the pressure roller is suspended on one side of the pressure roller, which will further increase the deviation.

[0004] To address the aforementioned problems, this application proposes a traction fixing structure for calendering processing. Utility Model Content

[0005] The purpose of this invention is to provide a traction and fixing structure for calendering, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a traction and fixing structure for calendering, including a calender and its internal calendering rolls;

[0008] The calender is provided with a traction mechanism on the left side, which consists of two horizontal fixed plates. A lower bracket and an upper bracket are detachably installed between adjacent traction mechanisms. The left side of the lower bracket extends outward to form a protruding support plate. The channel between the lower bracket and the upper bracket corresponds to the middle position of adjacent calender rolls.

[0009] Both the lower bracket and the upper bracket are divided into left and right separate plates, and a cleaning roller is rotatably installed inside the circular groove of the separation area. A cleaning frame with an arc-shaped outer surface is provided on the lower right side of the cleaning roller. The cleaning frame is in close contact with the cleaning roller. A square side groove extends from the lower right end of the circular groove, and the cleaning frame is located inside the side groove.

[0010] Preferably, the front and rear ends of the left and right separation plates of the lower bracket and the upper bracket are connected and fixed by a connecting plate, and the protruding shafts at both ends of the cleaning roller are rotatably connected to the connecting plate.

[0011] Preferably, the gap between the circular groove and the cleaning roller is greater than the gap between the arc-shaped surface of the cleaning frame and the cleaning roller.

[0012] Preferably, the cleaning rack has plates extending to the right at both ends to abut against the inner side of the side groove.

[0013] Preferably, a base plate is bolted to the lower end of the cleaning rack, and the base plate blocks the bottom opening between the cleaning rack and the side groove.

[0014] Preferably, both the bottom of the cleaning rack and the side groove have outwardly extending grooves for housing the base plate.

[0015] Preferably, the mounting structure of the cleaning roller and the cleaning frame is the same in both the lower bracket and the upper bracket.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses the pre-clamping of the lower and upper brackets to transport the material to be calendered within a fixed area and apply a certain pressure. At the same time, the increased clamping surface forms traction on the material and resists the displacement caused by deformation, so that the material to enter the space between adjacent calendering rolls is in a stable conveying state, thereby improving the calendering process quality.

[0018] This invention rotates along with the material during the material's conveying process while it is being clamped and supported, thereby adsorbing impurities on its surface and scraping them off by the cleaning frame and storing them in a circular groove. This achieves a self-cleaning effect on the material, preventing unevenness during calendering and ensuring the quality of the finished product.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-4 As shown, this utility model is a traction and fixing structure for calendering, including a calender 1 and its internal calendering rolls 2;

[0033] A traction mechanism 3 is provided on the left side of the calender 1, consisting of two horizontally fixed plates. A lower support 41 and an upper support 42 are detachably installed between adjacent traction mechanisms 3. Two plates protrude from the lower support 41 and the upper support 42. The protruding mechanisms opposite to the traction mechanism 3 are fixed by bolts. The left side of the lower support 41 extends outward to form a protruding support plate, which is used to increase the support range for the material. The channel between the lower support 41 and the upper support 42 corresponds to the middle position of the adjacent calender rolls 2. The lower support 41 and the upper support 42 simultaneously squeeze the upper and lower surfaces of the material, forming traction while fixing it to prevent displacement during calendering deformation and to ensure processing quality.

[0034] Both the lower bracket 41 and the upper bracket 42 are divided into left and right separation plates. A cleaning roller 401 is rotatably installed inside the circular groove 402 in the separation area. When the material passes through, it adsorbs the impurities on its surface to achieve a cleaning effect. A cleaning frame 405 with an arc-shaped outer surface is provided on the lower right side of the cleaning roller 401. The arc-shaped surface of the cleaning frame 405 is in contact with the outer surface of the cleaning roller 401. The scraper structure at the upper end of the arc-shaped surface of the cleaning frame 405 scrapes off the impurities adsorbed by the cleaning roller 401 and stores them in the square side groove 403 extending from the lower right end of the circular groove 402. The cleaning frame 405 is located in the left side area inside the side groove 403.

[0035] Furthermore, connecting plates 404 are provided at both ends of the left and right separation plates of the lower bracket 41 and the upper bracket 42. The two ends of the connecting plates 404 are connected and fixed to the two separation plates of the lower bracket 41 and the upper bracket 42 by rear bolts. The two ends of the cleaning roller 401 protruding shafts are rotatably connected to the holes in the center of the connecting plates 404.

[0036] Furthermore, the gap between the circular groove 402 and the cleaning roller 401 is larger than the gap between the arc surface of the cleaning frame 405 and the cleaning roller 401. By widening the gap, impurities are prevented from being scraped off prematurely when the cleaning roller 401 rotates.

[0037] Furthermore, the front and rear ends of the cleaning rack 405 extend to the right with plates that abut against the inner side of the side groove 403, thereby blocking the front and rear openings. The front and rear ends of the cleaning rack 405 are fixed to the connecting plate 404 by bolts.

[0038] Furthermore, a base plate 406 is bolted to the lower end of the cleaning rack 405. The base plate 406 blocks the bottom openings of the cleaning rack 405 and the side groove 403, thereby forming a closed side groove 403 for storing impurities. The bottoms of both the cleaning rack 405 and the side groove 403 have outward-extending grooves to house the base plate 406, preventing the base plate 406 from protruding downwards and blocking the material, thus preventing jamming.

[0039] Furthermore, the mounting structures for the cleaning roller 401 and the cleaning frame 405 are identical in both the lower bracket 41 and the upper bracket 42.

[0040] It is understandable that this utility model can clean the impurities on the surface of the material in real time during the calendering operation to prevent the formation of uneven structures during calendering. At the same time, it can also extend the support and traction range of the material and form a clamp, which can resist the oblique displacement force generated by calendering deformation and keep the part of the material to be fed into the pressure roller 2 in a straight conveying state, preventing the suspended conveying method from aggravating deviation.

[0041] A specific application of the operation process in this embodiment is as follows: During use, the material first passes through the channel between the lower support 41 and the upper support 42. During the conveying process, the cleaning roller 401 rotates and adsorbs impurities on its surface in real time. Then, when the side of the cleaning roller 401 that adsorbs impurities rotates to the area where the cleaning frame 405 is located, the impurities are scraped off by the arc end of the cleaning frame 405 and stored inside the circular groove 402. After the calender 1 has been running for a predetermined time, the bottom plate 406 can be removed to clean the stored impurities. During the material conveying process, the lower part is supported by the lower support 41 and the upper part is pressed down by the upper support 42 to form a limit. This lengthens the support surface so that the material is kept in a straight conveying state. Then, combined with the clamping force, the material is pulled and limited so that the surface material is displaced during calendering deformation, thereby ensuring the quality of the calendered product.
