Description

Technical Field

[0001] This utility model relates to the field of tire retreading technology, and in particular to a tire grinding and bonding integrated machine. Background Technology

[0002] In tire retreading, tread grinding and bonding are crucial steps and among the most important pieces of equipment. Their main function is to grind away the tread pattern of the old tire and bond the new tread to the ground, uniformly roughened surface. The quality of the grinding and bonding determines the overall quality of the retreaded tire.

[0003] In recent years, with the development and application of green tire recycling and remanufacturing mobile service platform technology, there is a demand for tire retreading grinding and bonding machines to be installed on mobile retreading vehicles. However, most grinding and bonding equipment on the market currently uses single-station grinding machines and independent tread bonding machines, which occupy a large area and are only suitable for centralized factory production. They cannot meet the requirements of mobile retreading vehicles. At the same time, independent grinding and bonding machines need to be removed after tire grinding and installed on the bonding machine for tread bonding. This results in tire retreading requiring two clamping operations. Multiple clamping operations are prone to precision deviations, increase the labor intensity of workers, and lead to low retreading efficiency and high labor costs. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0030] Example:

[0031] like Figures 1-10As shown, this utility model provides a tire grinding and bonding integrated machine, including a base 1. The base 1 is provided with two workstations. Each workstation is provided with a tire mounting drive device, a thickness measuring device, a bonding device, and a cutting device. A grinding device for grinding the tire is provided on one side of each workstation. The grinding device can switch between the two workstations via a first sliding device. An expansion hub 2 for clamping the tire is fixedly mounted on the tire mounting drive device. The thickness measuring device is used to detect the base rubber thickness of the tire and is connected to the grinding device via a signal. The bonding device is used to bond the new tire tread to the tire body. The cutting device is used to cut off the excess new tire tread.

[0032] Furthermore, the tire mounting drive device includes a mounting frame 22, a main shaft 23, a motor 24, a chain 25, sprockets, and a rotary joint 26. The mounting frame 22 is fixedly mounted on the base 1. The main shaft 23 is rotatably mounted on the mounting frame 22. The main shaft 23 is hollow inside. One end of the main shaft 23 is fixedly mounted with and connected to the expansion hub 2, and the other end is mounted with the rotary joint 26. The motor 24 is fixedly mounted on the mounting frame 22. Both the motor 24 and the main shaft 23 are equipped with sprockets. The two sprockets are driven by the chain 25.

[0033] In use, the tire to be retreaded is placed on the expansion hub 2 and aligned. Compressed air is injected into the expansion hub 2 through the rotary joint 26 and the main shaft 23, causing the expansion hub 2 to expand and clamp the tire on it. Then, the motor 24 drives one of the sprockets to rotate. Under the action of the chain 25, the sprocket on the main shaft 23 rotates synchronously, thereby driving the tire on the expansion hub 2 to rotate.

[0034] Furthermore, the thickness measuring device includes a cylinder 27, a fixing plate 28, a thickness gauge 29, and rollers 30. The cylinder 27 is fixedly mounted on the top of the mounting frame 22 via a mounting rod 31 and a fixing plate 28. The piston rod of the cylinder 27 is fixedly connected to the fixing frame 32. The thickness gauge 29 is fixedly mounted on the fixing frame 32, and the rollers 30 are rotatably mounted on the fixing frame 32 on both sides of the thickness gauge 29.

[0035] A guide rod 33 is provided on one side of the cylinder 27. The guide rod 33 passes through the fixing plate 28 and its bottom end is fixedly connected to the fixing frame 32, which plays a good guiding role.

[0036] During the tire tread polishing process, cylinder 27 drives the thickness gauge 29 to extend, and the rollers 30 on the fixed frame 32 are close to the tire surface. The thickness gauge 29 is installed between the two rollers 30. It detects the thickness of the rubber at the base of the tire through electromagnetic induction and sends a feedback signal to the polishing device.

[0037] Furthermore, the bonding device includes an intermediate pressure roller 13, a splitting pressure roller 14, a second cylinder 15, a swing arm 16, and a driving component. The swing arm 16 is rotatably mounted on the mounting rod 31. The cylinder body of the second cylinder 15 is hinged to the mounting frame 22. The piston rod of the second cylinder 15 is hinged to the swing arm 16. A fixed seat 17 is fixedly mounted at the front end of the swing arm 16. The intermediate pressure roller 13 is fixedly mounted on the front side of the fixed seat 17. Two splitting pressure rollers 14 are provided on the fixed seat 17. The driving component is used to control the opening and closing of the two splitting pressure rollers 14.

[0038] Furthermore, the driving component includes a third cylinder 18, a second motor 19, a lead screw 20, and a mounting block 21. The cylinder body of the third cylinder 18 is fixedly mounted on the mounting block 21. The piston rods of the two third cylinders 18 are respectively fixedly connected to the corresponding two separating and merging pressure rollers 14. The lead screw 20 is horizontally mounted on the fixed seat 17. The mounting block 21 is threadedly connected to the lead screw 20. The lead screw 20 includes a first lead screw 201 and a second lead screw 202. The first lead screw 201 and the second lead screw 202 are fixedly connected and have opposite thread directions. The mounting blocks 21 of the two separating and merging pressure rollers 14 are respectively threadedly connected to the corresponding first lead screw 201 and second lead screw 202. The second motor 19 is fixedly mounted on one end of the fixed seat 17, and the second motor 19 is drivenly connected to the lead screw 20.

[0039] Cylinder 2 (15) pulls the swing arm 16 down, and the intermediate pressure roller 13 presses onto the tire with the new tread. After the new tread is initially attached to the tire, cylinder 3 (18) pushes the separating and joining pressure roller 14 onto the tire tread. Motor 2 (19) drives the lead screw 20 to rotate. Since the lead screw 20 consists of two sections with opposite thread directions, it can drive the separating and joining pressure roller 14 to separate left and right, pressing out air bubbles between the new tread and the tire body, ensuring that the new tread and the tire body are tightly attached together. After pressing is completed, the separating and joining pressure roller 14 retracts and merges, and cylinder 2 (15) drives the swing arm 16 to rise.

[0040] Furthermore, the cutting device includes a support frame 3, a first connecting rod 4, a second connecting rod 5, a bracket 6, and a jigsaw. The support frame 3 is fixedly installed on the base 1. The first connecting rod 4 is rotatably installed on the top of the support frame 3, and the second connecting rod 5 is rotatably installed on the other end of the first connecting rod 4. The bracket 6 is fixedly installed on the top of the second connecting rod 5. The bracket 6 is used to overlap the new tire tread, and the new tire tread is cut by the jigsaw.

[0041] A fixing rod 34 is hinged to the base 1, and the fixing rod 34 is located between the slide rail 8 and the support frame 3. When the bracket 6 rotates to the front side of the expansion hub 2, the fixing rod 34 is used to limit the position of the bracket 6 by means of bolts, etc., to prevent the position of the bracket 6 from shifting during the cutting process.

[0042] During use, the worker holds a jigsaw and cuts the new tire tread with the strip-shaped slot on the bracket 6. After the cutting is completed, the bracket 6 is rotated to the outside to make room for the operator.

[0043] Furthermore, the first sliding device includes a cylinder 7, a slider, and a slide rail 8. The cylinder 7 is fixedly installed on the base 1, and the piston rod of the cylinder 7 is fixedly connected to the grinding device. The slide rail 8, which is arranged parallel to the two workstations, is installed on the base 1. The slider is fixedly installed at the bottom of the grinding device, and the slider is slidably connected to the slide rail 8.

[0044] Furthermore, the grinding device includes a second sliding component 36, a transmission component 37, an angle adjustment component, a third sliding component 38, and a grinding wheel 9. The second sliding component 36 drives the grinding wheel 9 to move toward the expansion hub 2 via a cylinder, a slider, and a slide rail, and is located above the first sliding device. The transmission component 37 drives the grinding wheel 9 to rotate via a motor, sprocket, chain, etc. The angle adjustment component is used to adjust the angle of the grinding wheel 9. The third sliding component 38 finely adjusts the distance between the grinding wheel 9 and the tire via a cylinder, a slider, and a slide rail. The third sliding component 38 is located above the second sliding component 36 and runs in the same direction as the second sliding component 36. The transmission component 37 and the grinding wheel 9 are mounted on the third sliding component 38 via a mounting base 35.

[0045] Furthermore, the angle adjustment component includes a motor 10, a gear 11, and a gear 2 12. The motor 10 is located below the third sliding component 38 and is drivenly connected to the gear 11. The gear 2 12 is installed on the top of the second sliding component 36 and meshes with the gear 11.

[0046] The working principle is as follows:

[0047] The tire to be retreaded is placed on the expansion hub 2 and aligned. The tire inflation button of the first station is activated. Compressed air is used to fix and clamp the tire through the rotary joint 26, the main shaft 23 and the expansion hub 2. The motor 3 24 is started to drive the tire to start rotating. At the same time, the grinding device is driven by the cylinder 7 to move horizontally to the position corresponding to the rotating tire.

[0048] The grinding wheel 9 is driven to rotate at high speed by the transmission component 37. Under the action of the second sliding component 36, the grinding wheel 9 moves forward to the surface of the tire to be ground and reaches the set pressure. At the same time, during the grinding process, the thickness gauge 29 can automatically detect the thickness of the belt layer steel wire to the tire surface. According to the set thickness of the belt layer steel wire to the tire surface, the thickness measuring device will feed back the thickness signal to the transmission motor of the grinding device in real time during the grinding process, and control the grinding wheel 9 to automatically adjust the grinding radius until the set thickness of the belt layer to the tire surface is reached.

[0049] After the tires at the first workstation are finished being ground, the grinding device moves to the corresponding position at the second workstation and performs the same actions as described above for the tires at the second workstation.

[0050] Meanwhile, the first station, which has been polished, begins the tread bonding process. The new tread, which has been prepared in advance and coated with adhesive, is initially bonded to the tire manually. Then, cylinder 2 15 pushes the swing arm 16 down, and the intermediate pressure roller 13 pre-presses on the tire with the bonded tread. At the same time, under the action of cylinder 3 18, the two separating pressure rollers 14 are pushed out onto the tire tread. Motor 2 19 starts and drives the lead screw 20 to rotate, which in turn drives the two separating pressure rollers 14 to separate left and right, pressing out the air bubbles between the new tread and the tire body, ensuring that the new tread and the tire body are tightly bonded together.

[0051] After the pressing is completed, the separating and joining pressure rollers 14 retract and merge, and cylinder 2 15 drives the swing arm 16 to lift. During the bonding process, excess new tire tread is manually cut off by the cutting device.

[0052] After the tread bonding is completed and passes the quality inspection, the tire on the first station is deflated, removed, and the next tire is installed before pre-grinding. The second station uses the same grinding procedure as the first station to grind the tire until it is finished. The same tread bonding and cutting steps as the first station are repeated, and the cycle continues.
