Description

Technical Field

[0001] This utility model relates to the field of tire retreading and polishing technology, and in particular to a tire retreading and polishing device with a flipping structure. Background Technology

[0002] With the development of the automotive industry and the increasing frequency of tire use, tire retreading and polishing technologies have gradually attracted attention. Tire retreading is a technology that extends the service life of old tires by repairing and refurbishing them, which not only saves resources but also reduces environmental pollution.

[0003] A search revealed that Chinese patent CN221159770U discloses a tire retreading and polishing device with a flipping structure. The device comprises a drive wheel, a support roller, a polishing assembly, a first support plate, a second support plate, brushes, a pin connector, an elastic component, and a coil spring. As the second support plate rotates, the brushes on both the first and second support plates come into contact with the tire. The drive wheel then rotates the tire, allowing the brushes to wipe and clean the tire's tread and sidewalls. This automatic and rapid flipping and cleaning of the tire during polishing ensures that no other debris adheres during the polishing process, thus guaranteeing the effectiveness of subsequent adhesive application and bonding.

[0004] In actual use, this patent has the following drawbacks:

[0005] In this patent, the distance between the two drive wheels is difficult to adjust, making it inconvenient to support and fix tires of different sizes, resulting in low versatility. Furthermore, this patent makes it difficult to disassemble and clean the brush, and after prolonged use, debris and other impurities on the brush will affect subsequent tire cleaning. Utility Model Content

[0006] In view of the technical problems in the prior art, such as inconvenience in supporting and fixing tires of different sizes, low versatility, and inconvenience in disassembling and cleaning the brush, this utility model provides a tire retreading and polishing device with a flipping structure.

[0007] The technical solution adopted by this utility model is: a tire retreading and polishing device with a flipping structure, including a worktable, a mounting frame fixedly installed above the worktable, a first electric push rod fixedly installed above the mounting frame, the first electric push rod passing through the mounting frame, a polishing wheel fixedly installed at the bottom end of the first electric push rod, a fixing plate fixedly installed on one side of the worktable, and a fixing component installed on one side of the fixing plate to facilitate the support and fixing of tires of different sizes, the fixing component including a mounting frame, and cleaning components for easy cleaning of tires installed on both sides of the mounting frame. The fixing component can support and fix tires of different sizes, improving the practicality of the device. The cleaning component can clean debris from the tire surface and can quickly disassemble the cleaning brush for easy cleaning or replacement.

[0008] Furthermore, a first motor is fixedly installed on one side of the mounting frame, and a first bevel gear is fixedly installed at the output end of the first motor. Second bevel gears mesh with the upper and lower surfaces of the first bevel gear. Threaded rods are fixedly installed on one side of each of the two second bevel gears, and connecting rods are threaded onto the surfaces of each of the two threaded rods. The two connecting rods pass through the upper and lower sides of the mounting frame and are slidably connected to the mounting frame. An arc-shaped plate is fixedly installed at one end of each of the two connecting rods. The first motor drives the first bevel gear to rotate, thereby causing the second bevel gears and threaded rods on both sides to rotate, which in turn causes the connecting rods on both sides to move towards or away from the arc-shaped plate. This achieves rapid and accurate fixing of tires of different sizes, ensuring the stability of the tires during the grinding process.

[0009] Furthermore, a limiting plate is fixedly installed at one end of each of the two connecting rods, and both limiting plates are slidably connected inside the mounting frame to limit the movement of the connecting rods.

[0010] Furthermore, two symmetrical mounting plates are fixedly installed inside the mounting frame, and the two threaded rods pass through the two mounting plates respectively and are rotatably connected to the mounting plates, so that the threaded rods can rotate smoothly in a fixed position, further improving the stability and durability of the device.

[0011] Furthermore, silicone pads are fixedly installed on the surfaces of both curved plates. The use of silicone pads increases the friction between the curved plates and the tire, preventing the tire from slipping during the polishing process and protecting the tire surface from damage.

[0012] Furthermore, a second motor is fixedly installed at one end of the fixing plate, and a rotating rod is fixedly installed at the output end of the second motor. One end of the rotating rod is fixedly connected to one side of the mounting frame, which allows the tire to be easily rotated, facilitating all-round grinding and cleaning of the tire and improving work efficiency.

[0013] Furthermore, the cleaning assembly includes two second electric push rods fixedly installed on both sides of the mounting frame. Both second electric push rods are arranged through one side of the mounting frame, and a connecting plate is fixedly installed at one end of each of the two second electric push rods. A cleaning brush is provided on one side of each of the two connecting plates. The second electric push rods drive the cleaning brushes to move towards the tire to clean the debris on the tire after grinding.

[0014] Furthermore, a sliding groove is formed on one side surface of the connecting plate, and mounting slots are formed on both the upper and lower sides of the sliding groove. A spring is fixedly installed inside the mounting slot, and a snap-fit ​​block is fixedly installed at one end of the spring. Two mounting rods that fit into the sliding groove are fixedly installed on the back of the cleaning brush. Snap-fit ​​slots that fit into the snap-fit ​​blocks are formed on both the upper and lower sides of the mounting rods. The cleaning brush is inserted into the sliding groove through the mounting rods, and quick installation and disassembly are achieved through the cooperation of the snap-fit ​​blocks and snap-fit ​​slots, facilitating cleaning and replacement.

[0015] Furthermore, both sides of the snap-fit ​​block are beveled, and the side closer to the mounting groove is wider. The beveled design makes it easier for the mounting rod to be inserted into the sliding groove and guides the snap-fit ​​block smoothly into the snap-fit ​​groove.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up a fixing component, this utility model can support and fix tires of different sizes, which improves the practicality of the device and solves the problem that existing devices are not convenient for supporting and fixing tires of different sizes and have low versatility.

[0018] 2. Secondly, through the setting of the cleaning component, this utility model can clean the debris on the tire surface and can quickly disassemble the cleaning brush for easy cleaning or replacement. This solves the problem that existing devices are not convenient for disassembling and cleaning the brush, and after long-term use, debris and other impurities on the brush will affect the subsequent tire cleaning work.

[0026] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0027] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a tire retreading and polishing device with a flipping structure.

[0028] The specific technical solution includes a workbench 1, a mounting frame 2 fixedly installed above the workbench 1, a first electric push rod 3 fixedly installed above the mounting frame 2, the first electric push rod 3 passing through the mounting frame 2, a grinding wheel 4 fixedly installed at the bottom end of the first electric push rod 3, a fixing plate 5 fixedly installed on one side of the workbench 1, a fixing component 6 for supporting and fixing tires of different sizes installed on one side of the fixing plate 5, the fixing component 6 including a mounting frame 601, and cleaning components 7 for cleaning tires installed on both sides of the mounting frame 2. The fixing component 6 can support and fix tires of different sizes, improving the practicality of the device, and the cleaning component 7 can clean debris from the tire surface.

[0029] Reference Figure 1 and Figure 3 As shown, a first motor 602 is fixedly mounted on one side of the mounting frame 601. A first bevel gear 603 is fixedly mounted on the output end of the first motor 602. Second bevel gears 604 mesh with the upper and lower surfaces of the first bevel gear 603. Threaded rods 605 are fixedly mounted on one side of each of the two second bevel gears 604. Connecting rods 606 are threadedly connected to the surfaces of the two threaded rods 605. The two connecting rods 606 pass through the upper and lower sides of the mounting frame 601 respectively and are slidably connected to the mounting frame 601. An arc-shaped plate 607 is fixedly mounted on one end of each of the two connecting rods 606, and a limiting plate 608 is fixedly mounted on one end of each of the two connecting rods 606. Both limiting plates 608 are slidable. Connected inside the mounting frame 601, characterized in that two symmetrical mounting plates 609 are fixedly installed inside the mounting frame 601, and two threaded rods 605 pass through the two mounting plates 609 respectively and are rotatably connected to the mounting plates 609; characterized in that silicone pads 610 are fixedly installed on the surfaces of the two arc-shaped plates 607; characterized in that a second motor 611 is fixedly installed at one end of the fixed plate 5, and a rotating rod 612 is fixedly installed at the output end of the second motor 611; one end of the rotating rod 612 is fixedly connected to one side of the mounting frame 601; the first motor 602 drives the first bevel gear 603 to rotate, thereby driving the two second bevel gears 604 meshing with it to rotate. The rotation of the second bevel gear 604 drives the threaded rod 605 to rotate. Since the threaded rod 605 is threadedly connected to the connecting rod 606 and the connecting rod 606 is limited by the limiting plate 608, the connecting rods 606 on both sides will move towards each other or in opposite directions, thereby pushing the arc plates 607 on both sides to move towards the inner wall of the tire and fixing the tire. The second motor 611 drives the rotating rod 612 to rotate, thereby causing the mounting frame 601 and the tire to flip over, so as to facilitate all-round grinding and cleaning.

[0030] Reference Figure 1 , Figure 2 and Figure 4As shown, the cleaning component 7 includes two second electric push rods 701 fixedly installed on both sides of the mounting frame 2. Both second electric push rods 701 extend through one side of the mounting frame 2. A connecting plate 702 is fixedly installed at one end of each of the two second electric push rods 701. A cleaning brush 703 is provided on one side of each connecting plate 702. The characteristic feature is that a sliding groove 704 is formed on one side surface of each connecting plate 702. Mounting grooves 705 are formed on both the upper and lower sides of the sliding grooves 704. A spring 706 is fixedly installed inside the mounting groove 705. A locking block 707 is fixedly installed at one end of each spring 706. Two mounting rods 707 that fit into the sliding grooves 704 are fixedly installed on the back of the cleaning brush 703. 08. The mounting rod 708 has locking grooves 709 on both its upper and lower sides that fit into the locking block 707. The locking block 707 has beveled surfaces on both sides, with the side closer to the mounting groove 705 being wider. The connecting plate 702 of the second electric push rod 701 and the cleaning brush 703 are close to the tire surface for easy cleaning of grinding debris. When the mounting rod 708 is inserted into the sliding groove 704, the locking block 707 retracts into the mounting groove 705, compressing the spring 706. When the locking groove 709 moves to the locking block 707, the locking block 707, under the action of the spring 706, engages with the locking groove 709, thereby fixing the cleaning brush 703 to the connecting plate 702. For disassembly, simply apply a certain external force to disengage the locking block 707 from the locking groove 709.

[0031] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0032] In use, first place the hollow center of the tire in the mounting frame 601. Start the first motor 602 to drive the first bevel gear 603 to rotate, which in turn drives the two meshing second bevel gears 604 to rotate. The rotation of the second bevel gears 604 drives the threaded rod 605 to rotate, and the connecting rods 606 on both sides move in opposite directions, thereby pushing the two arc-shaped plates 607 on both sides towards the inner wall of the tire to fix the tire. Then, start the first electric push rod 3 to drive the grinding wheel 4 to move downwards until it contacts the tire surface. Start the second motor 611 to rotate the tire, so that it can be ground in all directions. After grinding, start the two second electric push rods 701 to drive the two cleaning brushes 703 on both sides to move towards each other until they contact the two sides of the tire surface. Start the second electric push rod 602 to drive the two cleaning brushes 703 to move towards each other until they contact the two sides of the tire surface. The two motors 611 drive the tires to rotate, which can clean the surface debris. After cleaning, the cleaning brush 703 is pulled out and cleaned. After cleaning, the mounting rod 708 on the back of the cleaning brush 703 is inserted into the slide groove 704. The locking block 707 retracts into the mounting groove 705, and the spring 706 is compressed. When the locking groove 709 moves to the locking block 707, the locking block 707 is locked into the locking groove 709 under the action of the spring 706, thereby fixing the cleaning brush 703 to the connecting plate 702.
