Description

Technical Field

[0001] This utility model belongs to the field of rubber industry technology, specifically a rubber calendering device. Background Technology

[0002] Rubber calendering is a common processing technology, mainly used to produce rubber materials into sheets, films, or strips. Its purpose is to use a calender to squeeze, stretch, and flatten rubber mixtures at high temperatures between one or more pairs of rollers to obtain rubber products of the required thickness and shape. Rubber calendering equipment can calender rubber blocks or rubber mixtures into sheets or films of different thicknesses, which is crucial for the production of certain rubber products.

[0003] The principle of rubber calendering equipment mainly involves two aspects: calendering principle and plastic flow. By precisely applying the principles of calendering and plastic flow, rubber calendering equipment can efficiently calender rubber raw materials, providing strong support for the production of rubber products.

[0004] Existing calendering equipment often uses a conveyor belt to transport calendered rubber pads during calendering. The transported rubber pads are then directly piled up inside the storage box. When the rubber pads are directly piled up inside the storage box, the uneven stacking results in an uneven stacking layer, which affects the material retrieval efficiency in subsequent operations and increases the complexity and inconvenience of the operation. Therefore, a rubber calendering device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technology, existing calendering devices often transport calendered rubber pads via conveyor belts during calendering. The transported rubber pads are then directly piled up inside the storage box. When the rubber pads are directly piled up inside the storage box, the uneven stacking results in an uneven stacking layer, affecting the material retrieval efficiency in subsequent operations and increasing the complexity and inconvenience of the operation. This utility model proposes a rubber calendering device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a rubber calendering device, including a support bracket. Support legs are fixedly installed at all four ends of the bottom of the support bracket. A calendering device body is fixedly installed at one end of the top of the support bracket. First calendering rollers and second calendering rollers are rotatably installed at the upper and lower ends of the inner wall of the calendering device body, respectively. One end of each of the first and second calendering rollers is rotatably installed on one side of the inner wall of the calendering device body. The other ends of each of the first and second calendering rollers pass through the interior of the calendering device body and are fixedly installed with first and second rotating gears. The first and second rotating gears are meshed with each other. A second drive motor is fixedly installed on one side of the other end of the support bracket. A rotating rod is installed inside the support bracket through the output end of the second drive motor. A collecting roller is installed at the end of the rotating rod away from the second drive motor. The collecting roller is installed outside the support bracket at the end away from the rotating rod. The rubber raw material is calendered by multiple first calendering rollers and second calendering rollers. After forming, the collecting roller is driven by the second drive motor to collect the formed rubber pad. Then, the excess part is cut off by a cutting blade. By collecting the formed rubber pad, the rubber pad can be avoided from accumulating inside the storage box, thereby improving the material retrieval efficiency and production efficiency in subsequent operations.

[0007] Preferably, a support plate is fixedly installed on one side of the main body of the calendering device, and a first drive motor is fixedly installed on the top of the support plate. The output end of the first drive motor is installed inside one end of one of the second calendering rolls. A synchronous belt is installed between one end of the multiple first calendering rolls. The first drive motor drives one of the first rotating gears and the second rotating gear to rotate, and the synchronous belt can drive another set of first rotating gears and the second rotating gear to rotate, so as to achieve the effect of a single drive device driving multiple gear sets to rotate, thereby reducing the cost of use.

[0008] Preferably, cylinders are fixedly installed on both sides of one end of the support bracket. A lifting plate is installed at the output end of the cylinder. A sliding groove is opened at the bottom of the lifting plate. An electric slide rail is fixedly installed inside the sliding groove. A sliding block is slidably installed outside the electric slide rail. A cutting blade is fixedly installed at the bottom of the sliding block. The lifting plate is moved by the cylinder to keep the cutting blade at the same height as the rubber pad. The electric slide rail and the sliding block can drive the cutting blade to move horizontally to cut the rubber pad.

[0009] Preferably, one end of the support bracket has an installation groove, and a limiting plate is installed inside the installation groove. The outer side of the limiting plate is in close contact with the outer side of one end of the collecting roller. The limiting plate limits one end of the collecting roller so that it cannot deviate during rotation. When it is necessary to disassemble the collecting roller, the limiting plate is removed to release the limiting effect on one end and allow it to be disassembled.

[0010] Preferably, a plurality of connecting rods are fixedly installed on the outside of one end of the rotating rod, and a plurality of connection ports are opened inside one end of the collecting roller. One end of the plurality of connecting rods is respectively located inside the plurality of connection ports. Through the connection between the connection ports and the connecting rods, the effect of rotating the rotating rod and the collecting roller being detachable can be achieved.

[0011] Preferably, the top of the calender body is provided with a feeding port, and multiple guide plates are provided outside the feeding port. The multiple guide plates are distributed at an incline. A fixing plate is fixedly installed at the bottom of the guide plate. The end of the fixing plate away from the guide plate is fixedly installed on the top of the calender body. The guide plates limit the movement trajectory of the rubber raw material to be calendered, so that it moves directly between the multiple calender rolls for calendering.

[0012] The advantages of this utility model are:

[0013] This invention addresses the problem of existing calendering devices that use conveyor belts to transport calendered rubber pads, resulting in uneven accumulation inside storage boxes.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-6As shown, a rubber calendering device includes a support bracket 1. Support legs 3 are fixedly installed at all four ends of the bottom of the support bracket 1. A calendering device body 2 is fixedly installed at one end of the top of the support bracket 1. First calendering rollers 4 and second calendering rollers 5 are rotatably installed at the upper and lower ends of the inner wall of the calendering device body 2, respectively. One end of each of the first calendering rollers 4 and second calendering rollers 5 is rotatably installed on one side of the inner wall of the calendering device body 2. The other ends of each of the first calendering rollers 4 and second calendering rollers 5 are fixedly installed through the interior of the calendering device body 2 with a first rotating gear 6 and a second rotating gear 6. A moving gear 7, multiple first rotating gears 6 and second rotating gears 7 are meshed together. A second drive motor 11 is fixedly installed on one side of the other end of the support bracket 1. A rotating rod 12 is installed through the inside of the support bracket 1 at the output end of the second drive motor 11. A collecting roller 14 is installed at the end of the rotating rod 12 away from the second drive motor 11. The outer end of the collecting roller 14 away from the rotating rod 12 is installed inside the support bracket 1. During operation, existing calendering devices, when collecting calendered rubber pads, directly pile them inside the storage box, leading to... This causes significant inconvenience when material needs to be retrieved, affecting the efficiency of subsequent material retrieval operations. By starting the first drive motor 8, one of the second calendering rollers 5 rotates. The rotation of the second calendering roller 5 drives the first rotating gear 6 fixedly mounted on one end to rotate. When the first rotating gear 6 rotates, it drives the second rotating gear 7 meshing with it to rotate. The rotation of the second rotating gear 7 drives the synchronous belt 9 to rotate. When the synchronous belt 9 rotates, it drives another second rotating gear 7 to rotate. The rotation of this other second rotating gear 7 drives another first rotating gear 6 meshing with it to rotate, thus achieving the rotation of multiple... The simultaneous rotation of the first calendering roller 4 and the second calendering roller 5 allows the rubber raw material to be calendered by the mutual rotation of multiple first calendering rollers 4 and second calendering rollers 5. After calendering is completed, the calendered rubber pad is conveyed by the conveying device provided inside the support bracket 1. The second drive motor 11 can drive the collecting roller 14 to rotate and collect the calendered rubber pad. After collection is completed, the lifting plate 19 is moved downward by the cylinder 18. When it moves to a certain position, the sliding block 22 and the cutting blade 23 are moved by the electric slide rail 21 to achieve the effect of cutting the rubber pad.

[0024] A support plate 10 is fixedly installed on one side of the outer side of the main body 2 of the calendering device. A first drive motor 8 is fixedly installed on the top of the support plate 10. The output end of the first drive motor 8 is installed inside one end of one of the second calendering rollers 5. A synchronous belt 9 is installed between one end of multiple first calendering rollers 4. During operation, the existing calendering device directly piles the calendered rubber pads inside the storage box, which makes it very inconvenient to retrieve the material when needed, affecting the retrieval efficiency in subsequent operations. The first drive motor 8 drives the first rotating gear 6 and the second rotating gear 7 in one set of gears to rotate, while the synchronous belt 9 can drive the second rotating gear 7 in another set of gears to rotate, so that a single drive device can drive multiple sets of gears to rotate.

[0025] A cylinder 18 is fixedly installed on both sides of one end of the support bracket 1. A lifting plate 19 is installed at the output end of the cylinder 18. A sliding groove 20 is opened at the bottom of the lifting plate 19. An electric slide rail 21 is fixedly installed inside the sliding groove 20. A sliding block 22 is slidably installed outside the electric slide rail 21. A cutting blade 23 is fixedly installed at the bottom of the sliding block 22. During operation, the existing calendering device directly piles the calendered rubber pads inside the storage box, which makes it very inconvenient to retrieve the material when needed, affecting the retrieval efficiency in subsequent operations. The cylinder 18 drives the lifting plate 19 to move up and down, and the lifting plate 19 drives the cutting blade 23 to move vertically. The sliding installation between the electric slide rail 21 and the sliding block 22 drives the cutting blade 23 to move horizontally.

[0026] The support bracket 1 has an installation groove 16 inside one end, and a limiting plate 17 is installed inside the installation groove 16. The outer side of the limiting plate 17 is in close contact with the outer side of one end of the collecting roller 14. During operation, the existing calendering device directly piles the calendered rubber pads inside the storage box, which makes it very inconvenient to retrieve the material when needed, affecting the retrieval efficiency in subsequent operations. The limiting plate 17 limits one end of the collecting roller 14, preventing it from moving.

[0027] Multiple connecting rods 13 are fixedly installed on the outside of one end of the rotating rod 12, and multiple connecting ports 15 are opened inside one end of the collecting roller 14. One end of each of the multiple connecting rods 13 is located inside the multiple connecting ports 15. During operation, the existing calendering device directly piles the calendered rubber pads inside the storage box, which makes it very inconvenient to retrieve the material when needed, affecting the retrieval efficiency in subsequent operations. By setting the connecting rods 13 inside the connecting ports 15, the rotating rod 12 and the collecting roller 14 can be connected and rotated.

[0028] The calender body 2 has a feeding port at its top, and multiple guide plates 25 are provided outside the feeding port. The multiple guide plates 25 are distributed at an incline. A fixing plate 24 is fixedly installed at the bottom of the guide plate 25. The end of the fixing plate 24 away from the guide plate 25 is fixedly installed on the top of the calender body 2. During operation, the existing calendering device directly piles the calendered rubber pads inside the storage box, which makes it very inconvenient to retrieve the material when needed, affecting the retrieval efficiency in subsequent operations.

[0029] Working principle: During the production of rubber pads, when calendering the rubber raw material using a calendering device, the rubber raw material to be calendered is first placed into the main body 2 of the calendering device through the feed port. Then, the first drive motor 8 is started to drive one of the second calendering rollers 5 to rotate. The rotation of the second calendering roller 5 drives the first rotating gear 6 fixedly installed on one end to rotate. When the first rotating gear 6 rotates, it drives the second rotating gear 7 meshed with it to rotate. The rotation of the second rotating gear 7 drives the synchronous belt 9 to rotate. When the synchronous belt 9 rotates, it drives another second rotating gear 7 to rotate. The rotation of the other second rotating gear 7 drives the other rotating gear 7 meshing with it to rotate. Another first rotating gear 6 rotates, which drives multiple first calendering rollers 4 and second calendering rollers 5 to rotate simultaneously. When the rubber raw material is calendered by the mutual rotation of multiple first calendering rollers 4 and second calendering rollers 5, the calendered rubber pad is conveyed by the conveying device provided inside the support bracket 1 after calendering is completed. The second drive motor 11 can drive the collecting roller 14 to rotate and collect the calendered rubber pad. After collection is completed, the lifting plate 19 is moved downward by the cylinder 18. When it moves to a certain position, the sliding block 22 and the cutting blade 23 are moved by the electric slide rail 21 to achieve the effect of cutting the rubber pad.
