Description

Technical Field

[0001] This utility model relates to the field of vulcanized rubber processing technology, specifically to a device for calendering vulcanized rubber. Background Technology

[0002] In the production of inflatable balls, vulcanized rubber is the main material for the inner liner of inflatable balls. After vulcanization, the rubber needs to be repeatedly calendered. During the calendering process, the rubber can be adjusted to the required thickness to facilitate subsequent processing or finished product manufacturing. This not only improves the surface smoothness of the rubber, but also enhances its physical properties, such as tensile strength and wear resistance, thereby improving the quality of the subsequent ball inner liner production.

[0003] A rubber calendering device disclosed in Chinese Patent Publication No. CN218398951U drives gears to rotate via a motor output shaft, which in turn drives multiple connecting seats to rotate, thereby rotating multiple rollers to press rubber raw materials. The device uses movable components to cooperate with fixed grooves and limit strips to movably connect with the limit grooves, facilitating quick and easy assembly and disassembly of the rollers. However, the equipment for calendering vulcanized rubber has low flexibility and can only meet the processing requirements of a single thickness. It cannot stably adjust the calendering pressure for different types of ball liner processing, thus affecting the overall applicability of the equipment for calendering vulcanized rubber. Utility Model Content

[0004] The purpose of this invention is to provide a device for calendering vulcanized rubber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for calendering vulcanized rubber, comprising a base, a fixed plate fixedly connected to the middle position of one side of the top of the base, a hollow seat fixedly connected to one side of the fixed plate, a rotating mechanism provided at the bottom end of one side of the fixed plate, an impression roller mounted on one side of the rotating mechanism, a first handle mounted on one side of the outer side of the base, a positioning mechanism provided inside the first handle, a moving mechanism provided on one side of the first handle, a movable seat fixedly connected to the top of the moving mechanism, a second connecting block rotatably connected to the middle position of one side of the movable seat, an installation mechanism provided at the top of the hollow seat, and a third spring fixedly connected to the bottom end of the installation mechanism.

[0006] Preferably, connecting plates are slidably connected to both sides of the bottom of the hollow seat, a movable plate is fixedly connected to the top of the connecting plates, and a calendering roller is rotatably connected to the middle position of the lower ends of the two sets of connecting plates.

[0007] Preferably, the rotating mechanism includes a drive motor installed at the middle position of the bottom end of one side of the fixed plate, a first connecting block is installed at the output shaft end of the drive motor, and a cross groove that engages with the first connecting block is provided at the middle position of both sides of the impression roller.

[0008] Preferably, the positioning mechanism includes a positioning hole inside one side of the base, a pull rod slidably connected inside one side of the first throttle, a first movable block fixedly connected to one side of the pull rod, a first spring fixedly connected to one side of the first movable block, and a positioning rod that engages with the positioning hole fixedly connected to the side of the first movable block away from the first spring.

[0009] Preferably, the moving mechanism includes a threaded rod fixedly connected to the middle position of one side of the first throttle and threaded to the base, and a moving block rotatably connected to one side of the threaded rod and fixedly connected to the top end of the moving block.

[0010] Preferably, the installation mechanism includes slots on both sides inside the top of the hollow seat, a cover plate inserted into the top of the hollow seat, a second handle rotatably connected to the middle position of the top of the cover plate, a rotating shaft fixedly connected to the bottom end of the second handle, pull ropes fixedly connected to both sides of the rotating shaft, a second movable block fixedly connected to one side of the pull rope, a second spring fixedly connected to one side of the second movable block, and an insert block that engages with the slots fixedly connected to the side of the second movable block away from the second spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This equipment for calendering vulcanized rubber features a calendering roller at the top of an impression roller. When the calendering roller contacts the vulcanized rubber, a third spring is squeezed by a connecting plate and a movable plate. Due to the reaction force of the squeezed third spring, the calendering roller is pushed by the movable plate and the connecting plate to press the vulcanized rubber. Simultaneously, a cover plate and the third spring can be installed inside a hollow seat via an installation mechanism. When the cover plate and the third spring are removed from the top of the hollow seat, cover plates with third springs of different elasticity can be installed according to actual calendering requirements. This satisfies the calendering requirements of the rubber calendering equipment under various conditions and improves the overall applicability of the rubber calendering equipment.

[0013] 2. This equipment for calendering vulcanized rubber features a cross groove at the center of both sides of the impression roller. The first connecting block on the fixed plate and the second connecting block on the movable seat are inserted into the cross grooves on both sides of the impression roller, allowing for roller installation. Rotating the first handle on one side of the base moves the moving block and movable seat via a threaded rod. This allows the movable seat to pull the second connecting block out of the cross groove on one side of the impression roller. By replacing the impression rollers with different printing patterns, calendering of different ball-shaped inner tubes can be performed. The modular design improves the overall service life and flexibility of the rubber calendering equipment. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A device for calendering vulcanized rubber includes a base 1, a fixed plate 2 fixedly connected to the middle position of one side of the top of the base 1, a hollow seat 201 fixedly connected to one side of the fixed plate 2, a rotating mechanism 3 provided at the bottom of one side of the fixed plate 2, an impression roller 4 installed on one side of the rotating mechanism 3, a first handle 5 installed on one side of the outside of the base 1, a positioning mechanism 6 provided inside the first handle 5, a moving mechanism 7 provided on one side of the first handle 5, a movable seat 8 fixedly connected to the top of the moving mechanism 7, a second connecting block 801 rotatably connected to the middle position of one side of the movable seat 8, an installation mechanism 9 provided at the top of the hollow seat 201, and a third spring 10 fixedly connected to the bottom of the installation mechanism 9.

[0022] The hollow base 201 has two sliding connecting plates 202 on both sides of its bottom. The top of the connecting plates 202 is fixedly connected to a movable plate 203. A calendering roller 204 is rotatably connected to the middle position of the lower ends of the two sets of connecting plates 202. The top of the movable plate 203 is in contact with the third spring 10. The calendering roller 204 can be subjected to force by pressing the third spring 10 through the connecting plates 202 and the movable plate 203.

[0023] The rotating mechanism 3 includes a drive motor 301 installed at the middle position of the bottom end of one side of the fixed plate 2. A first connecting block 302 is installed at the output shaft end of the drive motor 301. A cross groove 401 that engages with the first connecting block 302 is provided at the middle position of both sides of the impression roller 4. When the drive motor 301 is started, it can drive the first connecting block 302 to rotate. At this time, the first connecting block 302 can push the impression roller 4 to rotate and push the vulcanized rubber at the middle position of the calendering roller 204 and the impression roller 4 to move.

[0024] The mounting mechanism 9 includes slots 205 on both sides of the top of a hollow base 201. A cover plate 901 is inserted into the top of the hollow base 201. A second handle 902 is rotatably connected to the middle of the top of the cover plate 901. A rotating shaft 903 is fixedly connected to the bottom of the second handle 902. Pull ropes 904 are fixedly connected to both sides of the rotating shaft 903. A second movable block 905 is fixedly connected to one side of the pull rope 904. A second spring 906 is fixedly connected to one side of the second movable block 905. An insert block 907 that engages with the slots 205 is fixedly connected to the side of the second movable block 905 away from the second spring 906. When the insert blocks 907 on both sides of the cover plate 901 are inserted into the hollow base 201... The slot 205 inside the core seat 201 allows for the connection and assembly of the cover plate 901 and the hollow seat 201. When the second handle 902 on the cover plate 901 is rotated, the second handle 902 can drive the rotating shaft 903 to rotate. At this time, the pull rope 904 can be pulled to move, and the pull rope 904 can pull the second movable block 905 to move, which can cause the second movable block 905 to squeeze the second spring 906 on one side. At the same time, the second movable block 905 can drive the insertion block 907 to move. When the second handle 902 is released, due to the reaction force of the second spring 906 being squeezed, the insertion block 907 can be pushed back to its original position by the second movable block 905.

[0025] Example 2 differs from Example 1 mainly in that:

[0026] A device for calendering vulcanized rubber includes a positioning mechanism 6 comprising a positioning hole 101 inside one side of a base 1, a pull rod 601 slidably connected inside one side of a first throttle 5, a first movable block 602 fixedly connected to one side of the pull rod 601, a first spring 603 fixedly connected to one side of the first movable block 602, and a positioning rod 604 that engages with the positioning hole 101 fixedly connected to the side of the first movable block 602 away from the first spring 603. Pulling the pull rod 601 can move the positioning rod 604 through the first movable block 602. When the positioning rod 604 is inserted into the positioning hole 101 on the base 1, the position of the first throttle 5 after rotation can be fixed.

[0027] The moving mechanism 7 includes a threaded rod 701 fixedly connected to the middle of one side of the first throttle 5 and threaded to the base 1. A moving block 702 is rotatably connected to one side of the threaded rod 701 and fixedly connected to the top of the moving seat 8. The first throttle 5 drives the threaded rod 701 to rotate, which can cause the threaded rod 701 to drive the moving seat 8 to move through the moving block 702. At the same time, the moving seat 8 can drive the second connecting block 801 to be pulled out from the cross groove 401 on the impression roller 4. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] In this embodiment of the application, the cover plate 901 equipped with the third spring 10 is inserted into the top of the hollow seat 201. At this time, the inserts 907 on both sides of the cover plate 901 can be inserted into the slots 205 in the hollow seat 201, and the connection and assembly of the hollow seat 201 and the cover plate 901 are completed. At this time, the vulcanized rubber to be calendered passes through the middle position between the impression roller 4 and the calendering roller 204. At the same time, the calendering roller 204 is subjected to force through the connecting plate 202 and the movable plate 203 to squeeze the third spring 10. Due to the reaction force of the third spring 10 being squeezed, the calendering roller 204 can be pushed to stick to the outer surface of the vulcanized rubber through the movable plate 203 and the connecting plate 202. At this time, the first connecting block 302 and the impression roller 4 can be rotated by starting the drive motor 301, thereby performing the calendering work of the vulcanized rubber.
