Description

Technical Field

[0001] This invention relates to the technical field of tin-plated coil conveying devices, and specifically to a scratch-resistant conveying and bearing structure for tin-plated coils. Background Technology

[0002] Metal coils, such as tin-plated coils, are core raw materials in precision sheet metal, packaging, and electronic hardware industries. Their overall processing flow includes multiple steps such as uncoiling, cutting, coating, and rewinding. Each step requires automated transfer, loading, and connection using specialized conveying equipment, which is a key link in ensuring continuous production. Currently, there are various types of conveying equipment suitable for metal coils in the industry, including roller conveyors, chain conveyors, belt conveyors, and walking beam conveyors. These types of equipment can adapt to different conveying distances, speeds, and load requirements, and are widely used in mass production of tin-plated coils and various steel coils. The core load-bearing components of existing conveying equipment are mostly external load-bearing structures. During operation, they generally adopt bottom lifting or external clamping methods, achieving positioning support and conveying by contacting the outer surface of the coil, thereby ensuring the basic stability of the coil transfer process.

[0003] However, the existing technology has the following problems:

[0004] When the conveying structure adopts a bottom rigid support or external clamping support method, due to the large weight of the metal coil and the precision tin-plated protective layer on the surface of the tin-plated coil, the coil is subjected to pressure from the bottom support component for a long time, which will form continuous compressive stress at the contact point, resulting in indentation marks. At the same time, there are slight sliding, vibration and displacement during the conveying process of the coil. The rigid support component continuously rubs and scrapes against the outer surface of the coil, which will directly wear down the surface tin plating layer, causing scratches and reducing the appearance quality of the coil. Summary of the Invention

[0005] The purpose of this invention is to provide a scratch-resistant conveying and bearing structure for tin-plated coils in order to solve the above-mentioned problems. It aims to overcome the defects of existing bearing structures that support the outside of the coil, which can easily lead to scratches or dents on the outside of the coil. Details are described below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a scratch-resistant conveying and supporting structure for tin-plated coils, comprising a base, an inner support assembly on the base, and two slide blocks slidably mounted on the base. A support shaft is mounted on each slide block, and a roller is slidably sleeved on the support shaft. Multiple support plates are provided on the roller. A linkage group is provided between the support plates and the roller. When the roller slides along the support shaft towards the slide block, it can drive the support plates to be pushed outwards via the linkage group. The base is provided with a driving component for moving the two slide blocks, and a support assembly for supporting the coil material.

[0008] Preferably, the linkage assembly includes a support, a first linkage, a base plate, and a second linkage. The support shaft has a flange at one end located inside the roller body. The support is connected to the flange of the roller body. The base plate is connected to the support plate. Both the first linkage and the second linkage are hinged to the base plate. The end of the first linkage away from the base plate is hinged to the support, and the end of the second linkage away from the base plate is hinged to the roller body.

[0009] Preferably, the roller body is provided with a first spring rod inside, and the two ends of the first spring rod are respectively connected to the support shaft flange and the inner wall of the roller body.

[0010] Preferably, the support plate is made of an elastic material and has two sets of creases that divide the support plate into a three-section structure. The three-section structure of the support plate consists of a middle section and two side sections. The base plate is connected to the middle section of the support plate. When the support plate abuts against the inner wall of the steel coil, it adapts to the curvature of the inner wall of the steel coil and forms a support through its own elasticity and bending deformation at the creases.

[0011] Preferably, a fork block is slidably connected through the substrate, a spring is provided between the fork block and the substrate, two support rods are connected to the fork block, a slider is connected to the end of the fork block away from the support plate, the slider slides through the roller body and extends into the inside of the roller body, a frustum shaft is slidably inserted to the end of the roller body away from the support shaft, one end of the frustum shaft protrudes from the end of the roller body, and the other end is provided with a conical outer wall, a second spring rod is connected between the frustum shaft and the roller body, and the slider slides against the conical outer wall of the frustum shaft.

[0012] Preferably, when the cone moves axially toward the slider, it can use the conical outer wall to push the slider toward the support plate, and the two support rods abut against the two side sections respectively after moving toward the support plate.

[0013] Preferably, the driving component includes a bidirectional lead screw and a motor. The bidirectional lead screw is rotatably mounted in the base, and the motor is mounted on the base. The output end of the motor is connected to the bidirectional lead screw. The bidirectional lead screw has two threads in opposite directions, and the two slides are respectively connected to the two threads to form a threaded transmission connection.

[0014] Preferably, the support assembly includes a pressure plate and a support block connected above it, a set of mounting seats are installed on the base, the pressure plate is vertically slidably connected to the set of mounting seats, a plurality of damping shock absorbers are connected between the bottom of the pressure plate and the top surface of the base, and the support block is covered with a flexible layer.

[0015] Preferably, the bottom of the pressure plate is connected to two pairs of connecting arms, and rollers are rotatably mounted on the two pairs of connecting arms. Wedges are connected to the sides of the two slides that are close to each other. When the two wedges are close to each other, they contact the two rollers respectively. When the wedges contact the rollers, the pressure plate is moved down by the rollers.

[0016] The beneficial effects are:

[0017] 1. This anti-scratch conveying and bearing structure for tin-plated coils, through the setting of the internal support component, allows multiple support plates on the two rollers to expand outward synchronously after the two rollers abut against each other, as the two slides continue to move, and finally contact the inner wall of the coil's central hole to form an internal support. This achieves the technical effect of supporting and fixing the coil from the central hole. Compared with the traditional external clamping support structure, this internal support method avoids contact friction between the clamping components and the outer surface of the coil, fundamentally eliminating the problems of scratches on the tin plating layer of the tin-plated coil and dents and deformations on the coil surface.

[0018] 2. This anti-scratch conveying and bearing structure for tin-plated coils, through the cooperation of support plates and abutment rods, allows the two abutment rods to reinforce the two sides of the three-section support plate. Furthermore, while the support plate is fully extended and fitted against the inner wall of the coil, it provides targeted reinforcement and support to the easily deformable side sections. This effectively solves the problems of insufficient support force and loose fit on both sides of the elastic support plate, ensuring that the support plate is fully fitted against the inner wall of the coil. This improves the stability and uniformity of the inner support fixation, preventing shaking and displacement due to uneven support force during coil conveying, and ensuring a smooth conveying process.

[0042] Please see Figure 1 - Figure 6 In one embodiment:

[0043] A scratch-resistant conveying and supporting structure for tin-plated coils includes a base 1 with an inner support assembly 2. The base 1 can be installed on various conveying devices, forming an independent conveying and supporting structure with the inner support assembly 2. The inner support assembly 2 includes two slides 21, both of which are slidably mounted on the base 1. A support shaft 22 is mounted on each slide 21. The base 1 is provided with a driving component 3 for moving the two slides 21. The driving component 3 includes a bidirectional lead screw 31 and a motor 32. The bidirectional lead screw 31 is rotatably mounted inside the base 1, and the motor 32 is mounted on the base 1. The output end of motor 32 is connected to the bidirectional lead screw 31. The bidirectional lead screw 31 has two threads in opposite directions. The two slides 21 are respectively connected to the two threads to form a threaded transmission connection. After the motor 32 starts, it drives the bidirectional lead screw 31 to rotate. Through the structural characteristics of its two sets of positive and negative threads, the bidirectional lead screw 31 converts the rotation of the motor 32 into the synchronous linear sliding motion of the two slides 21 in opposite directions. The threaded transmission connection has the advantages of high transmission accuracy, good self-locking, and smooth operation. It can accurately control the movement stroke and movement speed of the slides 21 and ensure the synchronicity of the movement of the two slides 21.

[0044] Specifically, a roller body 23 is slidably sleeved on the support shaft 22. Multiple support plates 29 are provided on the roller body 23. A linkage group is provided between the support plates 29 and the roller body 23. When the roller body 23 slides along the support shaft 22 towards the slide block 21, it can drive the support plates 29 to be supported outwards through the linkage group. A support assembly 4 for supporting the coil material is provided on the base 1. The coil material includes tin-plated coils and other metal coils. The support assembly 4 serves as a temporary bearing structure after the coil material is loaded. Before the inner support is fixed, it stably supports the coil material conveyed by the upstream conveying device. The upstream conveying device places the coil material on the support assembly 4. The drive unit... The component 3 drives the two slide blocks 21 to move closer to each other, so that the two rollers 23 are inserted into the middle hole from both ends of the coil material. Then the two rollers 23 abut against each other and exert force on each other. At this time, the two rollers 23 stop moving, while the two support shafts 22 continue to move closer to each other, so that the support shafts 22 and the rollers 23 move relative to each other. Multiple support plates 29 are evenly distributed on the outside of the rollers 23. When the support shafts 22 and the rollers 23 move relative to each other, the multiple support plates 29 are synchronously extended and extended by the mechanical linkage of the linkage group, so as to fit the inner wall of the coil material at multiple points and improve the support stability.

[0045] Furthermore, the linkage assembly adopts a figure-eight symmetrical hinge structure. The linkage assembly includes a support 25, a first connecting rod 26, a base plate 27, and a second connecting rod 28. The support shaft 22 has a flange at one end located inside the roller body 23. The support 25 is connected to the flange of the roller body 23. The base plate 27 is connected to the support plate 29. Both the first connecting rod 26 and the second connecting rod 28 are hinged to the base plate 27. The first connecting rod 26 and the second connecting rod 28 are symmetrically distributed in a figure-eight shape. The end of the first connecting rod 26 away from the base plate 27 is connected to the support 25. The second connecting rod 28 is hinged at one end away from the base plate 27 to the roller body 23. A first spring rod 24 is provided inside the roller body 23. The two ends of the first spring rod 24 are respectively connected to the flange of the support shaft 22 and the inner wall of the roller body 23. When the support shaft 22 and the roller body 23 move relative to each other, the first spring rod 24 is compressed. During this process, since the hinge point between the second connecting rod 28 and the roller body 23 remains stationary, while the hinge point between the support 25 and the first connecting rod 26 moves towards the second connecting rod 28, the first spring rod 24... During movement, the angle between the first connecting rod 26 and the second connecting rod 28 decreases, thereby pushing the base plate 27, which is hinged together by the two, outwards towards the roller body 23. The base plate 27 drives the support plate 29 to push outwards, so that after the two roller bodies 23 abut against each other, as the two slide blocks 21 continue to move, the multiple support plates 29 on the two roller bodies 23 can expand outwards synchronously, eventually contacting the inner wall of the central hole of the roll material and forming an internal support, thus achieving the technical effect of supporting and fixing the roll material from the central hole. Compared to traditional external clamping support structures, this internal support method avoids contact friction between the clamping components and the outer surface of the coil, eliminating the problems of scratches on the tin plating layer and dents and deformation of the coil surface from the root. During unloading, the two slides 21 move away from each other, and the first spring rod 24 between the roller 23 and the support shaft 22 pushes the support shaft 22 and the roller 23 to reset by its own elastic thrust. The connecting rod group then resets and drives the support plate 29 to retract automatically. Finally, the two rollers 23 disengage from the coil hole.

[0046] Furthermore, the support plate 29 is made of elastic material and has two sets of creases that divide it into a three-section structure. This three-section structure consists of a middle section and two side sections. The base plate 27 is connected to the middle section of the support plate 29. When the support plate 29 abuts against the inner wall of the steel coil, it adapts to the curvature of the inner wall of the steel coil and provides support through its own elasticity and bending deformation at the creases. The support plate 29 is made of a high-toughness elastic material, possessing both sufficient structural strength to bear the weight of the coil and good deformation recovery ability, avoiding the compression caused by rigid support. The inner wall of the coil is worn and indented. The two sets of creases are controllable deformation structures, which precisely divide the support plate 29 into three independent deformation areas. The middle section is fixedly connected to the base plate 27 to ensure the stability of the core support point. The two side sections can be freely bent and deformed by relying on the creases. When the support plate 29 expands outward to fit the inner wall of the coil hole, for metal coils with different inner diameters, the side sections can be bent by the creases and the fitting angle can be finely adjusted by the elasticity of the plate itself to achieve full-area fitting support, eliminating the situation of local suspension and local hard top, and thus adapting to coils with various specifications of hole.

[0047] Please see Figure 5 - Figure 10 In another embodiment:

[0048] A fork block 213 is slidably connected through the substrate 27. A spring is provided between the fork block 213 and the substrate 27. Two support rods 214 are connected to the fork block 213. A slider 212 is connected to the end of the fork block 213 away from the support plate 29. The slider 212 slides through the roller body 23 and extends into the roller body 23. A frustum shaft 210 is slidably inserted into the end of the roller body 23 away from the support shaft 22. One end of the frustum shaft 210 protrudes from the end of the roller body 23, and the other end has a conical outer wall. A first... The second spring rod 211 and the slider 212 slide against the conical outer wall of the frustum shaft 210. The second spring rod 211 is the elastic reset component of the frustum shaft 210. Under normal conditions, it maintains the convex state of the frustum shaft 210. The elastic coefficient of the second spring rod 211 is greater than that of the first spring rod 24. When the frustum shaft 210 moves towards the slider 212, it can use the conical outer wall to push the slider 212 towards the support plate 29. After the two support rods 214 move towards the support plate 29, they abut against the two side sections respectively.

[0049] More specifically, when the two rollers 23 are inserted into the hole of the roll material and come into contact with each other, the protruding parts of the two frustum shafts 210 first come into contact, and then they abut against each other, causing the rollers 23 and the support shaft 22 to move relative to each other first, and the two first spring rods 24 are compressed first. When the support plate 29 expands outward and forms a support, the rollers 23 and the support shaft 22 stop moving relative to each other. As the slide block 21 continues to move, the frustum shafts 210 continue to be compressed and retract into the rollers 23. Therefore, at this time, the two frustum shafts 210 simultaneously compress the second spring rods 211 and retract into the two rollers 23 respectively. When the frustum shafts 210 retract into the rollers 23, the conical outer wall of the frustum shafts 210 forms an inclined plane transmission structure. When the conical outer wall moves, it squeezes the multiple sliders 212 that come into contact with it. Using the principle of inclined plane compression, the sliders 212 are pushed to slide radially towards the support plate 29, so that the multiple sliders 212 simultaneously expand radially outward along the frustum shafts 210. The sliders 212 drive the fork blocks 213 synchronously. The spring between the moving and compressing fork block 213 and the base plate 27 is pushed by the two abutment rods 214 to precisely press the two side sections of the support plate 29. Since the three-section support plate 29 has already adhered to the inner wall of the central hole and completed adaptive deformation, the two abutment rods 214 reinforce the two side sections of the three-section support plate 29 by supporting and reinforcing them. Then, on the basis of the support plate 29 being fully expanded and adhered to the inner wall of the roll material, the easily deformable side sections are reinforced and supported at fixed points. This effectively solves the problem of insufficient support force and loose adhesion on both sides of the elastic support plate 29, allowing the support plate 29 to be fully adhered to the inner wall of the roll material, improving the stability and uniformity of the inner support fixation, and preventing shaking and deviation due to uneven support force during the roll material conveying process, ensuring a smooth conveying process. When the two rollers 23 are disengaged, the cone shaft 210 is reset by the second spring rod 211, and multiple sliders 212 are reset by the elastic force of the springs above them, so that all abutment rods 214 are simultaneously retracted and disengaged from the support plate 29.

[0050] Please see Figure 1 , Figure 2 , Figure 11 , Figure 12 In another embodiment:

[0051] It is worth noting that the support assembly 4 includes a pressure plate 42 and a support block 43 connected above it. A set of mounting seats 41 are installed on the base 1. The pressure plate 42 is vertically slidably connected to the set of mounting seats 41. Multiple damping shock absorbers 44 are connected between the bottom of the pressure plate 42 and the top surface of the base 1. The damping shock absorbers 44 are equipped with springs for reset. The support block 43 is covered with a flexible layer. The support block 43 is a load-bearing component that directly contacts the coil. The flexible layer covering the surface can effectively isolate the hard metal parts from the outer surface of the tin-plated coil, avoiding friction scratches or extrusion marks during coil feeding and temporary bearing. The pressure plate 42 bears the load of the support block 43 and the coil above it. Multiple damping shock absorbers 44 are evenly distributed between the pressure plate 42 and the base 1, thereby dispersing the load on the pressure plate 42. At the same time, the damping shock absorbers 44 can absorb the impact vibration when the upstream conveying device feeds the material. In addition, the damping shock absorbers 44 provide a certain downward space for the pressure plate 42.

[0052] It is worth mentioning that the bottom of the pressure plate 42 is connected to two pairs of connecting arms 45, and rollers 46 are rotatably mounted on each pair of connecting arms 45. Two wedges 47 are connected to the sides of the two slide blocks 21 closest to each other. When the two wedges 47 approach each other, they contact the two rollers 46 respectively. When the wedges 47 contact the rollers 46, the pressure plate 42 is moved downwards through the rollers 46. The connecting arms 45 extend downwards, and the rollers 46 are connected to the bottom ends of the connecting arms 45, creating a gap between the rollers 46 and the pressure plate 42 for the wedges 47 to pass through. The rollers 46 adopt a rotating mounting structure to reduce the frictional resistance when sliding in contact with the wedges 47. The contact surface is set as an inclined surface. When the two slide blocks 21 drive the wedge blocks 47 to approach each other, the inclined surface of the wedge blocks 47 gradually squeezes the roller 46. Through the squeezing force, the connecting arm 45 and the pressure plate 42 overcome the elastic force of the damping shock absorber 44 and move downward. At this time, the inner support assembly 2 has completed the inner support. Therefore, as the pressure plate 42 moves down, the bottom area of ​​the roll material is suspended, so that the roll material is completely fixed by the inner support assembly 2, thereby avoiding contact damage to the roll material by the external support. When unloading, as the two wedge blocks 47 are separated from the roller 46, the pressure plate 42 moves up and resets using the elastic reset ability of the damping shock absorber 44, and supports the lower part of the roll material again, which facilitates unloading.

[0053] The overall operation of the anti-scratch conveyor structure for tin-plated coils is as follows: the structure is installed on the compatible conveyor via the base 1. During operation, the upstream conveyor places the tin-plated coil or other metal coils on the support component 4 of the base 1. The coil is temporarily supported by the pressure plate 42 and the flexible support block 43 on top. The damping and shock-absorbing rods 44 evenly distributed between the pressure plate 42 and the base 1 can absorb the impact of feeding and equipment vibration, disperse the load, and provide vertical displacement and reset capability. Subsequently, the drive component 3 on the base 1 is activated, and the motor 32 drives the bidirectional lead screw 31 to rotate. The bidirectional lead screw 31 drives the two slidingly mounted slides 21 on the base 1 to move synchronously towards each other through the forward and reverse thread transmission structure of the bidirectional lead screw 31. This causes the support shaft 22 mounted on the slide 21 and the support shaft 22 to move synchronously towards each other. Rollers 23 are inserted into the middle from both ends of the hole in the roll material. After the ends of the cone shafts 210 protruding from the two rollers 23 abut against the limit, the rollers 23 stop moving. The slide block 21 continues to drive the support shaft 22 to move towards each other, so that the support shaft 22 and the rollers 23 slide relative to each other and compress the first spring rod 24 inside the rollers 23. At this time, the support 25 fixed on the flange of the support shaft 22 moves with the support shaft 22, which drives the first connecting rod 26 and the second connecting rod 28 with the figure-eight symmetrical hinge to reduce the included angle and push the base plate 27 outward in the hinge transmission mode. This causes the elastic three-section support plate 29 evenly distributed on the outside of the rollers 23 to open outward. The support plate 29 adapts to bending deformation by its own elasticity and the three-section structure formed by the two sets of creases, and fits and matches the curvature of the inner wall of the hole in the roll material to complete the initial internal support.

[0054] After the support plate 29 is initially supported and formed, the slide block 21 continues to move towards each other, causing the truncated cone shafts 210 protruding from the ends of the two rollers 23 to press against each other. The two rollers 23 move closer to each other, forcing the two truncated cone shafts 210 to overcome the elastic force of the second spring rod 211 with a larger elastic coefficient and contract inward into the roller 23. The conical outer wall of the truncated cone shaft 210 squeezes the slider 212 that slides through the roller 23 and moves radially outward, driving the fork block 213 slidably connected on the base plate 27 to compress its own matching spring and push the two support rods 214 to press against the two sides of the support plate 29, thereby achieving fixed-point reinforcement support of the support plate 29 and ensuring uniform adhesion and stable support of the inner wall of the roll material.

[0055] At the same time, the wedge 47, which moves synchronously with the slide block 21, gradually squeezes the roller 46, which is rotatably installed on the bottom connecting arm 45 of the pressure plate 42. The inclined extrusion transmission drives the pressure plate 42 to overcome the elastic force of the damping shock absorber 44 and move downward, so that the bottom of the roll material is suspended in the air. This allows the roll material to be completely fixed and transported without external contact by relying entirely on the inner support component 2, thus completely avoiding scratches and dents on the outer surface of the roll material.

[0056] When the roll material conveying operation is completed and unloading is required, the motor 32 reverses to drive the bidirectional lead screw 31 to rotate, causing the two slides 21 to move in opposite directions. The cone shaft 210 is released from pressure and resets under the action of the second spring rod 211. The slider 212, fork block 213 and support rod 214 spring back and reset in sequence and disengage from the support plate 29. At the same time, the support shaft 22 and roller body 23 reset under the elastic thrust of the first spring rod 24, causing the connecting rod group and support plate 29 to retract and reset, releasing the internal support fixing of the roll material hole. The wedge block 47 disengages from the roller 46 along with the slide 21. The pressure plate 42 moves upward and resets under the reset action of the damping shock absorber rod 44, and supports the bottom of the roll material again, completing the overall unloading process.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
