Description

Technical Field

[0001] This utility model belongs to the technical field of rotary systems, specifically relating to a rotary system suitable for a rubber roller storage device. Background Technology

[0002] Rubber rollers, as a type of roller product, are widely used in dyeing, printing, plastic processing and other fields. The common way to store rubber rollers is to stack them directly on the ground or place them on storage racks, but neither of these methods is convenient for accessing the rollers. Based on this, storage warehouses with rotating functions have been developed.

[0003] For example, patent (CN117184731A) discloses a horizontal multi-layer intelligent reel storage unit. Its sprocket drive assembly includes a drive chain and sprockets. The drive chain has multiple bends, and multiple sprockets mesh with it. Two sprocket drive assemblies are provided, with the sprocket axes of both assemblies arranged parallel to each other. The sprockets are fixedly mounted to a rotating shaft, which rotates to the frame. Both ends of a connecting shaft are fixedly connected to the drive chains of the two sprocket drive assemblies. The connecting shaft is rotatably connected to two suspension hooks. This reel storage unit achieves rolling storage of reels through the sprocket drive assembly. Production personnel can store and retrieve reels from a position that conforms to their ergonomic height, which not only improves work efficiency but also reduces the workload of production personnel. However, it also has the following drawbacks: the two ends of the connecting shaft are fixedly connected to the drive chain by snap-fit, and the connecting shaft is located outside the drive chain. When the connection point passes the upper steering sprocket, the end of the connecting shaft will obstruct the transmission between the drive chain and the upper steering sprocket, resulting in the drive chain jamming. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a rotary system suitable for a rubber roller storage device to solve the technical problem in the prior art where the end of the connecting shaft obstructs the transmission between the drive chain and the upper steering sprocket.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rotary system suitable for a rubber roller storage warehouse includes a frame and a rotary system located on the frame. The rotary system includes multiple sprockets distributed on the side of the frame and a transmission chain that meshes with the sprockets. The transmission chain has multiple bends. Each sprocket includes guide wheels at its four apex and multiple steering wheels distributed at different heights inside. The steering wheels include upper steering wheels and lower steering wheels. Connecting rods are provided between the transmission chains. Multiple connecting rods are evenly distributed on the transmission chain. Multiple receiving grooves are evenly spaced along the circumferential direction on the outer edge of the upper steering wheel. The arc length distance between adjacent receiving grooves is the same as the distance between adjacent connecting rods. During transmission, the connecting rods can be completely inserted into the receiving grooves.

[0007] Furthermore, the steering wheels are distributed in a "W" shape, and the steering wheels include 3 upper steering wheels and 2 lower steering wheels;

[0008] Furthermore, the end of the connecting rod is flat and the connecting rod is located on the outside of the transmission chain. Two fixing plates are arranged opposite each other on the inside of the transmission chain, and the connecting rod is fixedly connected to the fixing plates.

[0009] Furthermore, a hook is rotatably connected to the connecting rod;

[0010] Furthermore, a guide structure is provided between adjacent guide wheels. The guide structure includes a guide rail located inside the transmission chain. The guide rail is fixedly connected to the frame. The end of the connecting rod is rotatably connected to a guide ring that cooperates with the guide rail. A limiting plate is provided at the outer end of the guide ring. The limiting plate is in smooth contact with the outer surface of the guide rail.

[0011] Furthermore, a tightening structure is provided on the back of the upper steering wheel. The tightening structure includes a connecting plate that is fixedly connected to the frame. The connecting plate is located outside the support plate and the inner plate surface of the connecting plate is in contact with the outer plate surface of the support plate. Two vertical limiting grooves are provided on the connecting plate. A limiting rod that matches the limiting groove is provided on the outer surface of the support plate. The limiting rod passes through the connecting plate and a clamping nut is provided at the free end of the limiting rod.

[0012] Furthermore, the bottom of the connecting plate is provided with an inwardly extending horizontal boss, and a threaded hole is provided on the horizontal boss. An adjusting screw is provided in the threaded hole, and the tail end of the adjusting screw abuts against the bottom surface of the support plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) Compared with the prior art, by uniformly opening multiple receiving grooves along the circumferential interval on the outer edge of the upper steering wheel, and the arc length distance between adjacent receiving grooves is consistent with the distance between adjacent connecting rods, the connecting rod can be completely inserted into the receiving groove during the transmission process, thereby avoiding contact between the connecting rod and the meshing part of the upper steering wheel, thus effectively preventing the sprocket and the transmission chain from jamming. In addition, the opening size of the receiving groove is small and will not affect the normal transmission of the sprocket and the transmission chain.

[0015] (2) By setting up a tensioning structure, the height of the upper steering wheel can be adjusted to achieve the tensioning of the transmission chain. The entire adjustment process is simple to operate, and the transmission chain can be tensioned when needed to ensure the transmission efficiency of the entire rotary system.

Detailed Implementation

[0025] Example 1, specifically as follows Figures 1-6 As shown.

[0026] like Figure 1 As shown, a rotary system suitable for a rubber roller storage device includes a frame 1 and a rotary system 2 located on the frame 1. The frame 1 has an overall frame structure, which can effectively reduce its own weight while having good structural stability.

[0027] The rotary system 2 includes multiple sprockets 21 distributed on the side of the frame 1 and a transmission chain 23 meshing with the sprockets 21. The transmission chain 23 has multiple bends. The sprockets 21 are generally rectangular in shape, and each sprocket 21 includes guide wheels 211 at its four apex. Multiple steering wheels are staggered inside each sprocket. In this embodiment, the steering wheels are arranged in a "W" shape, including three upper steering wheels 213 and two lower steering wheels 212. The lower steering wheels 212 are at the same height as the bottom guide wheels 211, and the three upper steering wheels 213 are at the same height and are all located below the top guide wheels 211. In this embodiment, a rotary motor drives the lower steering wheels 212 to rotate, thereby enabling the entire rotary system 2 to operate.

[0028] Multiple support plates 11 are fixedly connected to the inner side of the frame 1 by welding. Each support plate 11 corresponds to a sprocket 21, and the two are rotatably connected by a shaft. This is existing technology, so it will not be described in detail.

[0029] Connecting rods 24 are provided between the two transmission chains 23. Multiple connecting rods 24 are evenly distributed on the transmission chains 23, with flat ends and located on the outer side of the transmission chains 23. In this embodiment, two fixing plates 231 are provided opposite each other on the inner side of the transmission chains 23. The fixing plates 231 are integrally formed with the transmission chains 23 and have threaded holes. The ends of the connecting rods 24 also have threaded holes located on both sides of the transmission chains 23. The connecting rods 24 are threadedly connected to the fixing plates 231 by screws, thereby achieving a fixed connection between the connecting rods 24 and the transmission chains 23. Two hooks are rotatably connected to the connecting rods 24, allowing for the hanging of stored items.

[0030] During actual operation, when the connecting rod 24 travels around the transmission chain 23 to the upper steering wheel 213, the connecting rod 24 is located between the upper steering wheel 213 and the transmission chain 23. That is, the meshing part of the connecting rod 24 and the upper steering wheel 213 comes into contact, thereby hindering the meshing transmission of the sprocket 21 and the transmission chain 23, making it impossible for the two to transmit power, causing the sprocket 21 and the transmission chain 23 to jam.

[0031] To avoid the above situation, multiple receiving grooves 22 are evenly spaced along the circumferential direction on the outer edge of the upper steering wheel 213. The arc length distance between adjacent receiving grooves 22 is consistent with the distance between adjacent connecting rods 24. During transmission, the connecting rods 24 can be completely inserted into the receiving grooves 22, thereby avoiding contact between the connecting rods 24 and the meshing part of the upper steering wheel 213, thus effectively preventing the sprocket 21 and the transmission chain 23 from jamming. In addition, the opening size of the receiving grooves 22 is small and will not affect the normal transmission of the sprocket 21 and the transmission chain 23.

[0032] In this embodiment, the receiving groove 22 is semi-circular, and a total of 5 receiving grooves 22 are provided. The distance between adjacent receiving grooves 22 is the arc length l. According to the arc length calculation formula, we know that: Where r is the radius of the upper steering wheel 213, n is the center of the circle between adjacent receiving slots 22, and the distance between adjacent connecting rods 24 can be determined by the arc length l.

[0033] A large gap between the guide wheels 211 can cause the transmission chain 23 between the guide wheels 211 to sag or swing during operation. Specifically, in the horizontal direction, the transmission chain 23 will sag under the influence of the weight of the suspended object and its own weight, and in the vertical direction, the transmission chain 23 will swing. Especially when the weight of the suspended object is large, the swing amplitude may affect normal operation.

[0034] Therefore, in this embodiment, a guide structure 25 is added between adjacent guide wheels 211, such as... Figure 1 As shown, the guide structure 25 includes four guide rails 251 located inside the transmission chain 23, two horizontally and two vertically. Multiple support blocks 252 are welded onto the frame 1. The guide rails 251 are fixedly connected to the frame 1 by welding to the support blocks 252. A guide ring 253 that cooperates with the guide rails 251 is rotatably connected to the end of the connecting rod 24.

[0035] By setting the guide structure 25, the guide rail 251 can provide continuous support for the guide ring 253 and the connecting rod 24 during operation, thereby effectively preventing the transmission chain 23 from sagging or swaying, and improving the overall stability of the rotary system. A limit plate 254 is welded to the outer end of the guide ring 253. The limit plate 254 is in smooth contact with the outer surface of the guide rail 251. By limiting the guide ring 253 and the connecting rod 24 through the limit plate 254, the swaying of the transmission chain 23 can be further restricted.

[0036] After prolonged or high-load operation, the transmission chain 23 will deform, mainly manifested as the transmission chain 23 becoming loose and the meshing degree between the transmission chain 23 and the sprocket 21 decreasing. On the one hand, this causes a significant loss of power during transmission, reducing equipment operating efficiency and increasing energy consumption. On the other hand, the loosening of the transmission chain 23 will increase the contact area between the transmission chain 23 and the sprocket 21, thereby increasing the friction between the two and shortening the service life. In severe cases, the transmission chain 23 may even fall off, causing serious safety accidents.

[0037] Based on this, in this embodiment, a tightening structure 26 is provided on the back of the upper steering wheel 213 in the center. The tightening structure 26 includes a connecting plate 261 that is welded and fixed to the frame 1. The connecting plate 261 is located outside the support plate 11 and the inner plate surface of the connecting plate 261 is in contact with the outer plate surface of the support plate 11. Two vertical limiting grooves 2611 are provided on the connecting plate 261 along the height direction. A limiting rod 262 that is adapted to the limiting grooves 2611 is threaded on the outer surface of the support plate 11. The limiting rod 262 passes through the connecting plate 261. A clamping nut 263 is provided at the free end of the limiting rod 262. By tightening the clamping nut 263, the support plate 11 and the connecting plate 261 can be fixed. The bottom of the connecting plate 261 is also provided with an inwardly extending horizontal boss 2612. The horizontal boss 2612 has a threaded hole, and a vertical adjusting screw 264 is threaded into the threaded hole. The tail end of the adjusting screw 264 abuts against the bottom surface of the support plate 11.

[0038] When the transmission chain 23 needs to be tensioned, first, loosen the clamping nut 263, and the support plate 11 can slide relative to the connecting plate 261. By tightening the adjusting screw 264, the support plate 11 and the upper steering wheel 213 are pushed to move upward along the limiting groove 2611. After reaching a suitable height, tighten the clamping nut 263 to fix the support plate 11 and the connecting plate 261 again.

[0039] By setting the tensioning structure 26, the height of the upper steering wheel 213 can be adjusted to achieve the tension of the transmission chain 23. The entire adjustment process is simple to operate, and the transmission chain 23 can be tensioned when needed to ensure the transmission efficiency of the entire rotary system.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
