Description

Technical Field

[0001] This utility model belongs to the field of rewinding machine technology, and in particular relates to a support device for an industrial quality inspection rewinding machine. Background Technology

[0002] Industrial quality inspection rewinding machines are specialized equipment used for rewinding paper, mica tape, film, and other materials. They play an important role in industries such as plastics, printing, lamination, and coating. They are used to rewind produced materials after quality inspection, controlling the quality and roll diameter of the finished product to meet industrial product specifications. The support device, as a crucial component of the industrial quality inspection rewinding machine, plays a key role in the stable operation of the equipment and the effective handling of materials. During the rewinding process, the winding rollers need to be stably supported to ensure smooth rewinding of the material.

[0003] However, some existing support devices make it difficult to quickly disassemble and install the winding roller. This not only consumes a lot of time and energy for operators and reduces work efficiency, but may also damage the winding roller and support device itself due to frequent improper operation, increasing equipment maintenance costs and affecting the continuity and stability of the entire production process. Utility Model Content

[0004] The purpose of this invention is to provide a support device for an industrial product inspection rewinding machine. It features a disassembly mechanism. Specifically, when installing the winding roller, the T-shaped block is aligned with the mounting groove and slid in, allowing the connecting plate to enter the mounting cavity. Rotating the bolt, in conjunction with the internal threaded block, pushes the extrusion block upwards, and the limiting block slides in the limiting groove. The extrusion block forces the fixing block against the connecting plate to complete the fixation. Disassembly is achieved by simply rotating the bolt in the opposite direction. This eliminates the need for complex tools, enabling rapid installation and removal of the winding roller, improving the replacement efficiency of the winding roller, ensuring the installation stability of the winding roller, reducing downtime, adapting to continuous production, and providing a reliable foundation for material winding. It solves the problem of existing support devices making it difficult to quickly disassemble and install the winding roller.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a support device for an industrial product inspection rewinding machine, comprising two support seats and winding rollers. Two support plates are fixedly connected between the two support seats. A rotating shaft passes through each of the two winding rollers, and the two rotating shafts are rotatably connected to their respective support seats. A motor is mounted on the right side of the right support seat, and the output shaft of the motor is fixedly connected to the corresponding rotating shaft via a coupling. The device also includes:

[0007] The disassembly mechanism comprises two sets, each set positioned at one end of two rotating shafts close to each other. The disassembly mechanism is used for quick disassembly and assembly of the winding roller. Each disassembly mechanism includes a mounting base fixedly connected to the left end of the rotating shaft. The mounting base has a mounting groove on its left side, and a T-shaped block is slidably connected to the inner wall of the mounting groove. The T-shaped block is fixedly connected to the winding roller.

[0008] An anti-loosening mechanism is provided between two support plates. The anti-loosening mechanism is used to prevent material from loosening during the winding operation of the winding roller. The anti-loosening mechanism includes a mounting plate, and an anti-loosening roller is rotatably connected to the top of the mounting plate.

[0009] The two rotating shafts are rotatably connected to their respective support seats via bearings, and the motor is connected to its corresponding support seat via bolts.

[0010] Furthermore, the disassembly mechanism also includes a connecting assembly disposed on top of the mounting base, the connecting assembly being used to connect the winding roller to the mounting base; and

[0011] A fixing component is disposed inside the mounting base and is used to fix the winding roller on the mounting base;

[0012] A drive assembly is disposed at the bottom of the mounting base, and the drive assembly is used to provide power for fixing the winding roller of the fixing assembly.

[0013] Furthermore, the anti-loosening mechanism also includes a moving component disposed at the bottom of the winding roller, the moving component being used to move the mounting plate and the anti-loosening roller; and

[0014] A reset assembly is used to reset the moving assembly after it has moved the mounting plate and the anti-loosening roller.

[0015] In this process, the material wound by the winding roller pushes the anti-loosening roller to move. After the anti-loosening roller moves, the cooperation between the moving component and the reset component enables the anti-loosening roller to adapt to the thickness of the material wound by the winding roller.

[0016] Furthermore, the connecting assembly includes a mounting cavity formed inside the mounting base, and two connecting plates are fixedly connected to the bottom of the T-shaped block. The bottoms of the two connecting plates extend into the interior of the mounting base and are slidably connected to the mounting cavity.

[0017] Both connecting plates are adapted to the mounting cavity.

[0018] Furthermore, the fixing component includes two fixing blocks slidably connected to the inner wall of the mounting cavity, and a pressing block is slidably connected to the inner wall of the mounting cavity. Each of the two fixing blocks has a limiting groove on the side near the pressing block, and the pressing block has a limiting block on the side near the two fixing blocks. The two limiting blocks extend into the corresponding limiting groove and are slidably connected to the corresponding limiting groove.

[0019] The two fixing blocks are designed as triangles, while the extrusion block is designed as a trapezoid, narrower at the top and wider at the bottom.

[0020] Furthermore, the drive assembly includes an internally threaded block fixedly connected to the bottom of the mounting base, a bolt passing through the internally threaded block, the bolt being threadedly connected to the internally threaded block, and the top end of the bolt being rotatably connected to the pressing block.

[0021] The bolts are rotatably connected to the extrusion block via bearings.

[0022] Furthermore, the movable component includes a support rod fixedly connected between two support plates, two rotating plates rotatably connected to the support rod, two connecting rods fixedly connected to the bottom of the mounting plate, hinge plates hinged between the bottom ends of the two connecting rods and the corresponding rotating plates, guide plates fixedly connected to the top of the two support plates, and the two connecting rods passing through the corresponding guide plates and slidably connected to the corresponding guide plates.

[0023] Both rotating plates are rotatably connected to the support rod via bearings.

[0024] Furthermore, sleeves are fixedly connected to the sides of the two support plates that are close to each other. Two through slots are respectively opened on the outer walls of the two sleeves. The sides of the two rotating plates away from the corresponding hinge plates pass through the corresponding sleeves and are slidably connected to the corresponding through slots. Springs are fixedly connected to the inner bottom walls of the two sleeves. Connecting rods are fixedly connected to the top ends of the two springs. Sliding grooves are opened on the two rotating plates. The two connecting rods pass through the corresponding rotating plates and are slidably connected to the corresponding sliding grooves.

[0025] Among them, the two connecting rods are respectively adapted to the corresponding sliding grooves.

[0026] This utility model has the following beneficial effects:

[0027] 1. This utility model features a disassembly mechanism. Specifically, during installation of the winding roller, the T-shaped block is aligned with the mounting groove and slid in, allowing the connecting plate to enter the mounting cavity. By rotating the bolt, the extrusion block is pushed upwards through its cooperation with the internal threaded block. The limiting block slides in the limiting groove, and the extrusion block forces the fixing block against the connecting plate to complete the fixation. During disassembly, the bolt is rotated in the opposite direction. No complicated tools are required, enabling rapid installation and removal of the winding roller, improving the replacement efficiency of the winding roller, ensuring the installation stability of the winding roller, reducing downtime, adapting to continuous production, and providing a reliable foundation for material winding.

[0028] 2. This utility model, by setting an anti-loosening mechanism, ensures that the anti-loosening roller contacts the material during winding. As the material thickens during winding, it pushes the anti-loosening roller downward, causing the mounting plate and connecting rod one to slide under the guidance of the guide plate. The hinge plate causes the rotating plate to rotate around the support rod, with one end sliding upward inside the sleeve. The sliding groove on the rotating plate drives the connecting rod two to stretch the spring. The spring's restoring force ensures that the anti-loosening roller always adheres to the material, ensuring that each layer is evenly compacted and preventing the material from becoming loose or misaligned during winding. This improves winding quality and facilitates storage, transportation, and subsequent processing.

[0029] 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

[0041] Please see Figure 1-7 As shown, this utility model is a support device for an industrial product inspection rewinding machine, including two support seats 1 and winding rollers 11. Two support plates 12 are fixedly connected between the two support seats 1.

[0042] The disassembly mechanism 2 consists of two sets, each located at one end of one of the two rotating shafts 13 that are close to each other.

When the bolt 242 is rotated, the pressing block 232 is moved by the threaded engagement between the bolt 242 and the internally threaded block 241.

[0052] The movable component 32 includes a support rod 321 fixedly connected between two support plates 12. Two rotating plates 322 are rotatably connected to the support rod 321. Two connecting rods 323 are fixedly connected to the bottom of the mounting plate 31. The bottom ends of the two connecting rods 323 are respectively hinged to the corresponding rotating plates 322 with hinge plates 324. Guide plates 325 are fixedly connected to the top of both support plates 12. The two connecting rods 323 pass through the corresponding guide plates 325 and are slidably connected to the corresponding guide plates 325. The two guide plates 325 are designed in an L-shape and are fixedly connected to the corresponding support plates 12 by welding.

[0053] Each of the two support plates 12 has a sleeve 331 fixedly connected to one side of each other. The outer walls of the two sleeves 331 each have two through slots. The sides of the two rotating plates 322 away from the corresponding hinge plates 324 each pass through the corresponding sleeves 331 and are slidably connected to the corresponding through slots. The inner bottom walls of the two sleeves 331 each have a spring 332 fixedly connected to one side. The top of each of the two springs 332 each has a connecting rod 333 fixedly connected to one side. Each of the two rotating plates 322 has a sliding groove 334. The two connecting rods 333 each pass through the corresponding rotating plate 322 and are slidably connected to the corresponding sliding groove 334. The two connecting rods 333 are fixedly connected to the corresponding springs 332 by welding.

[0054] A specific application of this embodiment is as follows: When using the device for winding operations, the motor 14 starts, and its output shaft drives the corresponding rotating shaft 13 to rotate through the coupling. The rotating shaft 13 transmits power to the winding roller 11 through the mounting base 21 and the disassembly mechanism 2, so that the winding roller 11 rotates synchronously with the rotating shaft 13. The rotating shaft 13 on the left side rotates on the corresponding support base 1 through the bearing driven by the winding roller 11, ensuring the stable rotation of the winding roller 11. As the winding roller 11 rotates, the externally conveyed material is continuously wound on the roller body, realizing the orderly winding of the material. When it is necessary to install the winding roller 11, the T-shaped block 212 on the winding roller 11 is aligned with the mounting groove 211 of the mounting base 21 and slid in, so that the T-shaped block 212 drives the two connecting plates 222 at the bottom into the mounting cavity 221. Then, the bolt 242 is rotated. The threaded engagement of bolt 242 with internal threaded block 241 causes bolt 242 to push extrusion block 232 upwards and move it within mounting cavity 221. As extrusion block 232 moves upwards, limiting blocks 234 on both sides slide within limiting grooves 233 of fixing block 231. The trapezoidal slope of extrusion block 232 presses against the slopes of two triangular fixing blocks 231, forcing the two fixing blocks 231 to slide to both sides and press tightly against the two connecting plates 222, thereby firmly fixing the winding roller 11 onto mounting base 21. When it is necessary to disassemble the winding roller 11, bolt 242 is rotated in the opposite direction. Bolt 242 drives extrusion block 232 downwards, and the extrusion force of extrusion block 232 on fixing block 231 disappears. Fixing block 231 no longer presses against connecting plate 222. At this time, T-shaped block 212 can be slid out of mounting groove 211, thus completing the disassembly of winding roller 11.

[0055] When the winding roller 11 is winding, as the material continuously winds around the winding roller 11, the thickness of the material gradually increases, which pushes the anti-loosening roller 311 to move downward. The anti-loosening roller 311 drives the mounting plate 31 to move downward. The two connecting rods 323 at the bottom of the mounting plate 31 slide under the guidance of the guide plate 325. At the same time, the hinge plate 324 pulls the two rotating plates 322 to rotate around the support rod 321. When the rotating plate 322 rotates, the end away from the hinge plate 324 slides upward in the through groove of the sleeve 331. At the same time, the sliding groove 334 on the rotating plate 322 slides relative to the connecting rod 333, pushing the connecting rod 333 to stretch the spring 332 in the sleeve 331, so that the spring 332 stores elastic potential energy. During the entire winding process... In the winding process, the restoring force of spring 332 acts on rotating plate 322 through connecting rod 333. Rotating plate 322, through hinge plate 324 and connecting rod 323, drives mounting plate 31 and anti-loosening roller 311 to always be tightly attached to the material surface, thereby generating continuous and uniform pressure on the material to prevent the material from becoming loose or misaligned between layers during winding, ensuring that the wound material is compact and regular. When the material on winding roller 11 is unloaded, the pushing force of the material on anti-loosening roller 311 disappears, spring 332 returns to its original position and contracts, thereby pulling connecting rod 333 downward, causing rotating plate 322 to rotate in the opposite direction, and then pulling mounting plate 31 and anti-loosening roller 311 to their original position through hinge plate 324 and connecting rod 323, preparing for the next winding operation.
