Description

Technical Field

[0001] This utility model relates to the field of tire vulcanizing bladder production technology, specifically a tire vulcanizing bladder trimming device. Background Technology

[0002] Tire vulcanizing bladders are mainly used to fill the tire with compressed air or steam during the vulcanization process, so that the tire maintains the correct shape in the mold and withstands a certain pressure, thereby ensuring that the tire rubber and ply layers and other components can be tightly bonded, vulcanized evenly, and obtain good physical properties and appearance quality.

[0003] During the production of tire bladders, some excess rubber edges or flash may appear on the edge of the bladder. These excess parts will affect the dimensional accuracy of the bladder, making it unable to fit precisely with the tire mold. By trimming, these excess rubber edges can be removed, so that the size of the bladder meets the design requirements.

[0004] Existing technology publication CN213563870U patent document provides a tire vulcanizing bladder auxiliary trimming device. In the tire vulcanizing bladder trimming process, the worker inserts the inner hole of the vulcanizing bladder into the outside of the support assembly, controls the rotation of the second motor, and drives the left inner clamping plate and the right inner clamping plate to rotate. The second pillar on the left inner clamping plate and the right inner clamping plate drives the tire support to rotate around the first pillar as the fulcrum. During the rotation, the tire support gradually extends and applies pressure to the side of the bladder to clamp it. The first motor is started, and the rotating rod drives the support assembly to rotate at a constant speed, thereby performing the trimming work on the vulcanizing bladder.

[0005] The aforementioned prior art, although the tire support gradually extends during rotation and applies pressure to the side of the capsule to clamp it, achieving the effect of clamping and fixing the capsule, requires the operator to hold a knife while trimming the tire capsule. During the trimming process, the operator may accidentally touch the knife and get injured. The device cannot automatically and effectively trim the tire capsule, reducing its practicality. Therefore, we need a tire vulcanizing capsule trimming device. Utility Model Content

[0006] The purpose of this utility model is to provide a tire vulcanizing bladder trimming device to solve the problem that in the trimming device of the patented technology mentioned in the background art, when trimming the tire bladder, the operator holds a knife and repairs along the edge of the tire bladder.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A tire vulcanizing bladder trimming device includes a base 1, a fixed box 2 is provided on the top of the base 1, and a drive assembly 3 is provided on the top of the fixed box 2. A mounting plate 5 is fixedly connected to the top of the base 1, and a detachable assembly 7 is provided on one side of the mounting plate 5. The drive assembly 3 includes a first motor 301, the output end of the first motor 301 is detachably connected to a lead screw 302 via a coupling, and a moving block 303 is threadedly connected to the outer surface of the lead screw 302. A second motor 304 is installed inside the fixed box 2, and the output end of the second motor 304 is detachably connected to a rotating rod 305 via a coupling. A connecting plate 306 is fixedly connected to one end of the rotating rod 305, a fixing block 307 is fixedly connected to the bottom of the connecting plate 306, and a ball bearing 308 is rotatably connected to the bottom of the fixing block 307. The detachable component 7 includes a connecting groove 701, and a connecting block 702 is engaged with the inner wall of the connecting groove 701. A positioning groove 703 is provided on one side of the connecting block 702, and a positioning block 704 is engaged with the inner wall of the positioning groove 703. A screw 705 is installed on the top of the mounting plate 5, and a lifting plate 706 is threadedly connected to the outer surface of the screw 705.

[0020] Through the above technical solution, starting the first motor 301 can drive the lead screw 302 to rotate and simultaneously move the moving block 303, thereby enabling the tire capsule installed on the limiting mechanism 4 to automatically move to one side of the cutter. After reaching the position, starting the second motor 304 can drive the rotating rod 305 to rotate and simultaneously drive the connecting plate 306 to rotate, thereby enabling the tire capsule to automatically rotate and cooperate with the cutter for trimming. No manual operation is required; the tire capsule only needs to be installed on the limiting mechanism 4, which improves the safety and practicality of the device.

[0021] Specifically, a limiting mechanism 4 is provided on the top of the fixed box 2, and an arc-shaped cutter 6 is installed on one side of the mounting plate 5.

[0022] Through the above technical solution, the cylinder on the limiting mechanism 4 can push the tire support to limit and fix the inner wall of the tire capsule. One side of the arc-shaped cutter 6 is an arc-shaped circumferential cutting tool, which can trim the surface of the tire capsule.

[0023] Specifically, the first motor 301 forms a moving structure with the moving block 303 via the lead screw 302, and the external thread of the lead screw 302 matches the internal thread of the moving block 303. The top of the moving block 303 is connected to the bottom of the fixed box 2.

[0024] The above technical solution facilitates the starting of the first motor 301, which drives the lead screw 302 to rotate and simultaneously drives the moving block 303 to move. Since the top of the moving block 303 is connected to the fixed box 2, the moving block 303 will drive the fixed box 2 to move during the movement. There are two moving blocks 303, and the other moving block 303 will slide synchronously on the fixed rod to maintain stability, so that the tire capsule installed on the fixed box 2 can automatically move towards the arc-shaped cutter 6.

[0025] Specifically, the second motor 304 forms a rotating structure with the connecting plate 306 via the rotating rod 305, and the rotating rod 305 is located between the second motor 304 and the connecting plate 306.

[0026] The above technical solution facilitates the starting of the second motor 304, which can drive the rotating rod 305 to rotate and simultaneously drive the connecting plate 306 to rotate. During the rotation of the connecting plate 306, the tire capsule will rotate, and then, in conjunction with the arc-shaped cutter 6, the outer surface of the tire capsule can be trimmed.

[0027] Specifically, the connecting plate 306 forms a rotating structure with the ball bearings 308 via the fixing block 307, and there are multiple ball bearings 308.

[0028] The above technical solution facilitates the rotation of the connecting plate 306, which causes the ball bearings 308 at the bottom of the fixing block 307 to roll on the fixing box 2, thereby improving the stability of the rotation of the connecting plate 306 and preventing tilting.

[0029] Specifically, the mounting plate 5 forms a locking structure with the connecting block 702 through the connecting groove 701, and one side of the connecting block 702 is connected to one side of the arc-shaped cutter 6. The connecting block 702 forms a locking structure with the positioning block 704 through the positioning groove 703, and the shape and size of the positioning groove 703 match the shape and size of the positioning block 704.

[0030] The above technical solution facilitates the connection of the arc-shaped cutter 6 to the mounting plate 5 by extending the connecting block 702 into the connecting groove 701, and the positioning block 704 extends into the positioning groove 703 to limit and fix the connecting block 702, thereby achieving the effect of fixed installation between the arc-shaped cutter 6 and the mounting plate 5.

[0031] Specifically, the mounting plate 5 forms a lifting structure with the lifting plate 706 via the screw 705, and the external thread of the screw 705 matches the internal thread of the lifting plate 706.

[0032] Through the above technical solution, the lifting plate 706 can be raised and lowered by manually rotating the screw 705. The threads on both sides of the screw 705 rotate in opposite directions, and the two lifting plates 706 are symmetrically arranged on both sides of the screw 705. This allows the two lifting plates 706 to rise and fall relative to each other, which in turn causes the two positioning blocks 704 to rise and fall relative to each other. This allows control over the movement of the positioning blocks 704, making it easier to replace the arc-shaped cutter 6.

[0033] Working Principle: When using this tire vulcanizing bladder trimming device, an external power supply is first installed to power the equipment inside. The tire bladder is first installed on the limiting mechanism 4, which then limits and fixes it. Next, the first motor 301 is started, driving the lead screw 302 to rotate. The lead screw 302 then moves the moving block 303, causing the tire bladder to move to one side of the arc-shaped cutter 6. Then, the second motor 304 is started, driving the rotating rod 305 to rotate. The rotating rod 305 then drives the connecting plate 306 to rotate. During the rotation of the connecting plate 306, the ball bearings 308 on the bottom fixing block 307 roll within the fixing box 2 to maintain stability, causing the limiting mechanism 4 at the top of the connecting plate 306 to rotate, which in turn causes the tire bladder to rotate, coordinating with... The arc-shaped cutter 6 cleans the burrs on the surface of the tire bladder. When the arc-shaped cutter 6 needs to be disassembled and polished, simply turn the screw 705 by hand to move the two lifting plates 706 outward, so that the lifting plates 706 move the positioning block 704 outward. The positioning block 704 disengages from the positioning groove 703, releasing the limiting fixation of the connecting block 702. The connecting block 702 on one side of the arc-shaped cutter 6 can then be pulled out from the connecting groove 701, completing the disassembly. During installation, simply reverse the screw 705 to move the lifting plate 706 inward, so that the positioning block 704 extends into the positioning groove 703 to fix the connecting block 702, thus fixing the arc-shaped cutter 6. This completes all the work. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
