Description

Technical Field

[0001] The present invention belongs to the technical field of rubber coating for fitness equipment, and particularly relates to a rubber coating device for fitness equipment processing. Background Art

[0002] Rubber coating is a process of wrapping one material on the surface of another material, aiming to endow the product with specific functions and characteristics. The common types of rubber coating generally include plastic coating on metal, rubber coating on metal, and rubber coating on metal. Its core advantages are reflected in performance optimization and function integration. This process combines the high strength of metal with the flexibility of elastomers, ensuring both structural rigidity and enhancing characteristics such as shock absorption, noise reduction, anti-slip, and insulation. At the same time, the rubber coating layer can significantly improve wear resistance, impact resistance, and corrosion resistance, extending the life of components. It is especially suitable for harsh environments such as mining machinery and conveying equipment. Metal rubber coating can effectively reduce the noise and vibration generated by metal contact, and has important application value in fields such as automation equipment and rail transit. At the same time, it realizes resource recycling by repairing damaged metal parts, combining economic and environmental benefits. In the application of the rubber coating process, most fitness equipment uses rubber coating to wrap the metal, which can provide better protection for the metal, avoiding corrosion when contacting air and providing a layer of protection when contacting the human body.

[0003] Due to the rise of the fitness industry, the sales volume of fitness equipment has gradually increased. In the process of using the existing rubber coating devices for fitness equipment, there are often problems of low efficiency when filling the rubber material. During the process of filling the rubber material, most are manually paved or paved with external simple auxiliary devices, which easily affect the continuity of the overall rubber coating device, thereby resulting in low efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a rubber coating device for fitness equipment processing.

[0005] The technical solution adopted to solve the above technical problem is: to provide a rubber coating device for fitness equipment processing, including a workbench, a bottom die mechanism is fixedly connected to the center of the top of the workbench, and a hydraulic mechanism is installed on the top of the workbench;

[0006] A limit connecting plate is arranged in the center of the hydraulic mechanism, and upper die mechanisms are fixedly connected to both sides of the bottom of the limit connecting plate. Turning mechanisms are fixedly connected to both sides of the top of the workbench;

[0007] Two clamping mechanisms are installed on each of the two turning mechanisms, feeding mechanisms are fixedly connected to the centers of both sides of the workbench, and a dumbbell body is placed on the bottom die mechanism.

[0008] Further, the bottom die mechanism includes a connecting bottom plate fixedly connected to the center of the top of the workbench. On both sides of the top of the connecting bottom plate, bottom die bodies are fixedly connected. Between the two bottom die bodies and the connecting bottom plate, a plurality of fixing bolt assemblies are installed.

[0009] Through the above technical solution, a cavity at the bottom is formed by the bottom die body. After placing the sheet material, the dumbbell body is placed, and then the sheet material is placed to cooperate with the upper die mechanism to realize die pressing. The two bottom die bodies and the connecting bottom plate can be fixed through a plurality of fixing bolt assemblies.

[0010] Further, the hydraulic mechanism includes a plurality of limiting support columns fixedly connected to the top of the workbench. Between the tops of the plurality of limiting support columns, a fixed top plate is fixedly connected. In the center of the fixed top plate, a hydraulic cylinder is installed.

[0011] Through the above technical solution, during use, the hydraulic cylinder is used to control the lifting of the limiting connecting plate, thereby driving the two upper die mechanisms to lift. At the same time, the plurality of limiting support columns can limit and guide the limiting connecting plate.

[0012] Further, the upper die mechanism includes a top die body fixedly connected to the bottom of the limiting connecting plate. On both sides of the top die body, a group of first limiting columns and a group of second limiting columns are respectively fixedly connected. At the front and rear ends of the top die body, electric rods are installed. The output ends of the two electric rods are fixedly connected with side sealing blocks. On both sides of the two side sealing blocks, limiting blocks are fixedly connected.

[0013] Through the above technical solution, during rubber coating, after sequentially placing the rubber sheet material, the dumbbell body, and the rubber sheet material, the hydraulic cylinder pushes the limiting connecting plate to descend, thereby realizing the combination between the two upper die mechanisms and the two bottom die bodies. The two second limiting columns play a role in limiting and guiding. Then, the two electric rods in the upper die mechanism will push the side sealing blocks to approach each other. A cavity is formed by the top die body, the bottom die body, and the two side sealing blocks. Then, the bottom die body and the top die body start to heat to melt the rubber sheet material, completely wrapping the dumbbell body in the cavity. After a period of time, under the drive of the hydraulic cylinder and the electric rods, the top die body and the side sealing blocks are reset, and the dumbbell body after rubber coating is taken out.

[0014] Further, the flipping mechanism includes two support columns and a first motor assembly fixedly connected to one side of the top of the workbench. Between the two support columns, a rotating rod is rotatably connected. The output end of the first motor assembly is fixedly connected with a driving gear. The front end of the rotating rod is fixedly connected with a driven gear. Between the two ends of the outer wall of the rotating rod, a support rod is fixedly connected.

[0015] Through the above technical solution, the first motor assembly drives the driving gear to rotate and then drives the driven gear meshing with it. The rotating rod will drive the supporting frame rod to rotate, thereby enabling the two clamping mechanisms on the supporting frame rod to be moved repeatedly, thereby realizing the loading and flipping function.

[0016] Furthermore, the clamping mechanism includes a connecting frame plate, one side of the connecting frame plate is fixedly connected to a limiting shell, a second motor assembly is installed on the top of the limiting shell, an output end of the second motor assembly is fixedly connected to a bidirectional threaded rod, both sides of the limiting shell are fixedly connected to side brackets, one end of the side bracket is fixedly connected to a connecting shaft, a clamping plate frame is rotatably connected to the connecting shaft, two threaded transmission plates are spirally connected to the bidirectional threaded rod, one side of the two threaded transmission plates are fixedly connected to a limiting sleeve plate, and one end of the two clamping plate frames is fixedly connected to a driving round rod.

[0017] Through the above technical scheme, when clamping, the two clamping mechanisms are flipped to the side of the feeding mechanism through the flipping mechanism, and the second motor assembly in the two clamping mechanisms drives the bidirectional threaded rod to rotate, and then drives the two threaded transmission plates to approach the center through the threaded structure, so that the two limit sleeves are close to the center. During the movement, the two driving round rods will be pushed closer to each other through the hollow structure of the two limit sleeves, and slide in the inner wall of the limit sleeve, so that the two clamping plate frames rotate on the connecting shaft, and then the protruding rubber material sheet is clamped through the other end of the two clamping plate frames.

[0018] Furthermore, the two threaded transmission plates slide closely against the inner wall of the limiting shell, the two driving round rods slide inside the corresponding limiting sleeves, and the thread structures at both ends of the bidirectional threaded rod are in opposite directions.

[0019] Through the above technical solution, the movement limit of the threaded transmission plate is achieved through the limit housing, and the driving of the driving round rod is achieved through the limit sleeve. The threaded structure of the bidirectional threaded rod ensures that the two threaded transmission plates will approach each other during rotation to achieve clamping.

[0020] Furthermore, the feeding mechanism includes a cylinder bracket fixedly connected to one side of the workbench and two material box brackets fixedly connected to one side of the top of the workbench, a driving cylinder is fixedly connected to the cylinder bracket, a push plate is fixedly connected to the output end of the driving cylinder, a feeding box is fixedly connected between the tops of the two material box brackets, and a plurality of rubber material plates are placed inside the feeding box.

[0021] Through the above technical solution, the cylinder bracket drives the push plate, and the bottom one of the multiple stacked rubber sheets inside the feeding box is pushed out through the push plate. The feeding function of the rubber sheets is realized by cooperating with the flipping mechanism and the clamping mechanism. Placing rubber sheets on the top and bottom of both sides of the dumbbell body can enable the melted rubber sheets to completely wrap the dumbbell body during the rubber coating process.

[0022] Furthermore, the tops of the two material box brackets are both inclined plane structures, and a rectangular through hole opposite to the rubber sheet is opened at one end of the top of the feeding box.

[0023] Through the above technical solution, the inclined plane structure ensures that after pushing out one rubber sheet and the driving cylinder drives the push plate to reset, the stacked rubber sheets can freely fall, and the opened rectangular through hole also ensures that only a single rubber sheet can be pushed out.

[0024] The beneficial effects of the present invention are as follows: (1) By designing the flipping mechanism, the clamping mechanism and the feeding mechanism, the present invention is driven by the first motor assembly in the flipping mechanism, and then the flipping movement of the clamping mechanism is driven through the driving gear, the driven gear, the rotating rod and the support rod. Then, through the drive of the second motor assembly, the clamping work of the rubber sheet is realized by cooperating with the bidirectional threaded rod, the threaded transmission plate, the limit sleeve, the driving round rod and the clamping plate frame. Finally, the rubber sheet is pushed out by the driving cylinder and the push plate, so that repeated feeding can be realized. Placing rubber sheets on the top and bottom of both sides of the dumbbell body can enable the melted rubber sheets to completely wrap the dumbbell body during the rubber coating process, reducing manual operation and effectively improving the rubber coating efficiency; (2) By designing that the tops of the material box brackets are both inclined plane structures, it is ensured that after pushing out one rubber sheet and the driving cylinder drives the push plate to reset, the stacked rubber sheets can freely fall, and at the same time, the moving formation of the clamping mechanism is reduced, improving the feeding efficiency, and when the clamping mechanism moves to both sides, it will not affect the descent of the limit connecting plate.

Detailed implementation manners

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] As Figures 1 - 3 shown, a rubber coating device for processing fitness equipment in this embodiment includes a workbench 1. A bottom die mechanism 2 is fixedly connected to the center of the top of the workbench 1. The bottom die mechanism 2 includes a connecting bottom plate 201 fixedly connected to the center of the top of the workbench 1. Both sides of the top of the connecting bottom plate 201 are fixedly connected with bottom die bodies 202. A plurality of fixing bolt assemblies 203 are installed between the two bottom die bodies 202 and the connecting bottom plate 201. A cavity at the bottom is formed by the bottom die bodies 202. After placing the sheet material, the dumbbell body 9 is placed, and then the sheet material is placed to cooperate with the upper die mechanism 5 to achieve die pressing. The two bottom die bodies 202 and the connecting bottom plate 201 can be fixed through the plurality of fixing bolt assemblies 203. A hydraulic mechanism 3 is installed on the top of the workbench 1. The hydraulic mechanism 3 includes a plurality of limiting support columns 301 fixedly connected to the top of the workbench 1. A fixed top plate 302 is fixedly connected between the tops of the plurality of limiting support columns 301. A hydraulic cylinder 303 is installed at the center of the fixed top plate 302. During use, the hydraulic cylinder 303 is used to control the lifting of the limiting connecting plate 4, thereby driving the two upper die mechanisms 5 to lift. At the same time, the plurality of limiting support columns 301 can limit and guide the limiting connecting plate 4.

[0042] As Figures 1 - 9 and Figure 14As shown in the figure, a limit connecting plate 4 is arranged at the center of the hydraulic mechanism 3. Both sides of the bottom of the limit connecting plate 4 are fixedly connected with upper die mechanisms 5. The upper die mechanism 5 includes a top die main body 501 fixedly connected to the bottom of the limit connecting plate 4. A group of first limit columns 502 and a group of second limit columns 503 are respectively fixedly connected to both sides of the top die main body 501. Electric rods 504 are installed at both the front and rear ends of the top die main body 501. The output ends of the two electric rods 504 are fixedly connected with side sealing blocks 505. Limit blocking blocks 506 are fixedly connected to both sides of the two side sealing blocks 505. During rubber coating, after placing the rubber material plate 806, dumbbell main body 9, and rubber material plate 806 in sequence, the hydraulic cylinder 303 pushes the limit connecting plate 4 to descend, thereby realizing the combination between the two upper die mechanisms 5 and the two bottom die main bodies 202. The two second limit columns 503 play a role in limit guiding. Then, the two electric rods 504 in the upper die mechanism 5 will push the side sealing blocks 505 to approach each other. A cavity is formed by the top die main body 501, bottom die main body 202, and the two side sealing blocks 505. Then, the bottom die main body 202 and the top die main body 501 start to heat to melt the rubber material plate 806, which completely wraps the dumbbell main body 9 in the cavity. After a period of time, driven by the hydraulic cylinder 303 and the electric rods 504, the top die main body 501 and the side sealing blocks 505 are reset, and the dumbbell main body 9 after rubber coating is taken out.

[0043] As Figures 1 - 3 shown, turnover mechanisms 6 are fixedly connected to both sides of the top of the workbench 1. The turnover mechanism 6 includes two support columns 601 and a first motor assembly 602 fixedly connected to one side of the top of the workbench 1. A rotating rod 603 is rotatably connected between the two support columns 601. The output end of the first motor assembly 602 is fixedly connected with a driving gear 604. The front end of the rotating rod 603 is fixedly connected with a driven gear 605. A support rod 606 is fixedly connected between the two outer ends of the rotating rod 603. The first motor assembly 602 drives the driving gear 604 to rotate, thereby driving the meshing driven gear 605. The rotating rod 603 that rotates accordingly will drive the support rod 606 to rotate, thereby enabling the two clamping mechanisms 7 on the support rod 606 to move repeatedly, realizing the feeding and turnover functions.

[0044] As Figures 1 - 10As shown in the figure, two clamping mechanisms 7 are installed on each of the two flipping mechanisms 6. The clamping mechanism 7 includes a connecting frame plate 701. One side of the connecting frame plate 701 is fixedly connected with a limiting housing 702. A second motor assembly 703 is installed on the top of the limiting housing 702. The output end of the second motor assembly 703 is fixedly connected with a bidirectional threaded rod 704. Side brackets 705 are fixedly connected to both sides of the limiting housing 702. One end of the side bracket 705 is fixedly connected with a connecting shaft 706. A clamping plate frame 707 is rotatably connected to the connecting shaft 706. Two threaded transmission plates 708 are helically connected to the bidirectional threaded rod 704. A limiting sleeve plate 709 is fixedly connected to one side of each of the two threaded transmission plates 708. One end of each of the two clamping plate frames 707 is fixedly connected with a driving round rod 710. When clamping, the two clamping mechanisms 7 are flipped to one side of the feeding mechanism 8 through the flipping mechanism 6. The second motor assembly 703 in the two clamping mechanisms 7 drives the bidirectional threaded rod 704 to rotate, and then drives the two threaded transmission plates 708 to approach the center through the threaded structure, so that the two limiting sleeve plates 709 approach the center. During the movement, the hollow structures of the two limiting sleeve plates 709 are used to push the two driving round rods 710 to approach each other and slide in the inner walls of the limiting sleeve plates 709, so that the two clamping plate frames 707 rotate on the connecting shaft 706, and then the other ends of the two clamping plate frames 707 are used to clamp the protruding rubber material plate 806. The two threaded transmission plates 708 both slide closely against the inner wall of the limiting housing 702, and the two driving round rods 710 both slide inside the corresponding limiting sleeve plates 709. The thread structure directions at both ends of the bidirectional threaded rod 704 are opposite. The movement of the threaded transmission plate 708 is limited by the limiting housing 702, and the driving of the driving round rod 710 is realized by the limiting sleeve plate 709. The thread structure of the bidirectional threaded rod 704 ensures that when rotating, the two threaded transmission plates 708 approach each other to realize clamping.

[0045] As Figures 1 - 14As shown, the centers of both sides of the workbench 1 are fixedly connected with a feeding mechanism 8, and the feeding mechanism 8 includes a cylinder bracket 801 fixedly connected to one side of the workbench 1 and two material box brackets 802 fixedly connected to one side of the top of the workbench 1, a driving cylinder 803 is fixedly connected to the cylinder bracket 801, and a pushing plate 804 is fixedly connected to the output end of the driving cylinder 803, and a feeding box 805 is fixedly connected between the tops of the two material box brackets 802, and a plurality of rubber material plates 806 are placed inside the feeding box 805. The cylinder bracket 801 drives the pushing plate 804, and the bottom one of the plurality of rubber material plates 806 stacked inside the feeding box 805 is pushed out by the pushing plate 804, and cooperates with the turning machine The structure 6 and the clamping mechanism 7 realize the feeding function of the rubber material sheet 806. Placing the rubber material sheets 806 at the top and bottom of both sides of the dumbbell body 9 respectively can make the melted rubber material sheets 806 completely wrap the dumbbell body 9 during the rubber encapsulation process. The tops of the two material box brackets 802 are both inclined structures, and a rectangular through hole opposite to the rubber material sheet 806 is opened at one end of the top of the loading box 805. The inclined structure ensures that after a rubber material sheet 806 is pushed out and the driving cylinder 803 drives the pushing plate 804 to reset, the stacked rubber material sheets 806 can fall freely, and the opened rectangular through hole also ensures that only a single rubber material sheet 806 can be pushed out. The dumbbell body 9 is placed on the bottom mold mechanism 2.

[0046] The working principle of this embodiment is as follows. When in use, the first motor assembly 602 drives the driving gear 604 to rotate and then drives the driven gear 605 meshing therewith. The rotating rod 603 that rotates accordingly drives the supporting frame rod 606 to rotate and moves the two clamping mechanisms 7 to the vicinity of the feeding mechanism 8. Then the cylinder bracket 801 drives the pushing plate 804, and through the pushing plate 804, multiple rubber material plates 806 stacked inside the feeding box 805 are pushed out one by one. Then the second motor assembly 703 in the two clamping mechanisms 7 drives the bidirectional threaded rod 704 to rotate, and then drives the two threaded transmission plates 708 to approach the center through the threaded structure, so that the two limit sleeves 709 are approached to the center. During the process, the two driving round rods 710 are pushed closer to each other through the hollow structure of the two limiting sleeves 709, and slide in the inner wall of the limiting sleeves 709, so that the two clamping plate frames 707 rotate on the connecting shaft 706, and then the other ends of the two clamping plate frames 707 are used to clamp the protruding rubber material sheet 806. After the clamping is completed, the first motor component 602 in the flipping mechanism 6 is driven in the reverse direction to reset the support frame rod 606, so that the rubber material sheet 806 clamped by the two clamping mechanisms 7 is at the top of the bottom mold body 202, and then the second motor component 703 in the clamping mechanism 7 is driven in the reverse direction, so that the rubber material sheet 806 loses its clamping and falls on the top of the bottom mold body 202;

[0047] Then, place the dumbbell body 9 between the rubber material plates 806 on the tops of the two bottom die bodies 202 at the top of the bottom die mechanism 2. Press the rubber material plates 806 into the interior of the bottom die body 202 by the weight of the dumbbell body 9. Then, similarly, use the flipping mechanism 6, the clamping mechanism 7, and the feeding mechanism 8 to clamp the rubber material plates 806 to the top of the dumbbell body 9 again. Then, the flipping mechanism 6 flips the two clamping mechanisms 7 to the side close to the feeding mechanism 8. Finally, the hydraulic cylinder 303 pushes the limit connecting plate 4 to descend, thereby realizing the combination between the two upper die mechanisms 5 and the two bottom die bodies 202. The two second limit posts 503 play a role in limit guiding. Then, the two electric rods 504 in the upper die mechanism 5 will push the side blocking blocks 505 to approach each other. A cavity is formed by the top die body 501, the bottom die body 202, and the two side blocking blocks 505, and the two rubber material plates 806 can wrap the dumbbell body 9. Then, the bottom die body 202 and the top die body 501 start to heat to melt the rubber material plates 806, and completely wrap the dumbbell body 9 in the cavity. After a period of time, driven by the hydraulic cylinder 303 and the electric rods 504, the top die body 501 and the side blocking blocks 505 are reset, and the dumbbell body 9 after encapsulation is taken out.

[0048] The above is only a preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
