Description

Technical Field

[0001] The invention relates to the technical field of vulcanization production equipment, in particular to inner tube vulcanization production equipment and a process with an inflation inspection function. Background Art

[0002] Vulcanization production equipment; the production process for electric bicycle and motorcycle inner tubes primarily includes: metering and batching, mixing, refining, filtering, extrusion, cooling, punching, talc powder spraying, cutting, splicing, vulcanization, and inflation testing. Vulcanization is essentially cross-linking, the process of converting the existing rubber molecular structure into a spatial network. The parked tube is pre-inflated before being loaded onto the vulcanizing machine to initiate vulcanization. After one vulcanization cycle, the vulcanizer automatically opens the mold, completing the vulcanization process. During the inflation test, an air compressor is used to inflate the tube and test for leaks, followed by a vacuum pump to restore the tube.

[0003] Patent (CN222201779U) provides a demoulding device for a motorcycle inner tube vulcanizer, specifically relating to the technical field of demoulding devices, including a frame, an upper mold movably mounted on the middle of the upper wall of the inner surface of the frame, a hydraulic rod fixedly mounted on the middle of the lower wall of the inner surface of the frame, the upper end of the hydraulic rod fixedly connected to the lower mold, and a control panel fixedly mounted on the left front end of the frame. The demoulding device for a motorcycle inner tube vulcanizer described in this utility model, through the provision of an ejector assembly and a protective assembly, enables the lower mold to be tightly attached to the inner surface of the lower mold by controlling the ejector assembly when placing the inner tube. At the same time, after processing, the mold can be demoulded by the ejector assembly, which is convenient for users to use and improves product quality. At the same time, the protective assembly can prevent the staff from accidentally touching the control panel after adjusting the program, thereby causing the machine to malfunction, making it convenient for users to use.

[0004] The inner tube vulcanizer in the above patent mainly relies on the cooperation of the upper mold and the lower mold to vulcanize the inner tube. However, the inner tube placement cavities of the upper and lower molds are both smooth surfaces. During the vulcanization process, the inner tube surface and the inner wall of the placement cavity fit together. This method easily leads to uneven vulcanization of the inner tube, resulting in poor vulcanization effect of the inner tube. Summary of the Invention

[0023] Working principle of the present invention: Refer to the instruction manual Figure 1-Figure 2 and Figure 4-Figure 9 The present invention pre-inflates the inner tube to be vulcanized by arranging a lower mold 2, an upper mold 3, an annular vulcanization cavity 4, a pulse extrusion mechanism 5 and an inflation and exhaust component 6. The inner tube is placed in a pre-expanded state after the pre-expanded treatment. The inner tube is placed in the annular vulcanization cavity 4 between the lower mold 2 and the upper mold 3, and then the upper mold 3 and the lower mold 2 are closed. The upper mold 3 and the lower mold 2 heat and vulcanize the inner tube in the annular vulcanization cavity 4, and the pulse extrusion mechanism 5 is started at the same time as the heating and vulcanization treatment. The pulse extrusion mechanism 5 The treated inner tube is subjected to pulse extrusion treatment, and after a vulcanization cycle, the vulcanizer automatically opens the mold to complete the vulcanization; the vulcanized inner tube is cooled and then the inflation and exhaust assembly 6 is used to inflate and exhaust the inner tube. During inflation, the built-in air pressure detector data is used to determine whether the inner tube is leaking; when the inner tube shows no leakage, the inner tube is exhausted and then packaged; when the inner tube shows leakage, the inner tube inflation inspection fails and is uniformly collected and processed, and subsequently reworked or the parts are directly disassembled and re-processed; In actual application, a heating component for the annular vulcanization cavity 4 is provided inside the upper mold 3 and the lower mold 2 (the annular vulcanization cavity 4 can be heated by contact heating using an electric heating mechanism or by filling the annular vulcanization cavity 4 with heated gas), for heating and vulcanizing the inner tube inside the annular vulcanization cavity 4. The heating component is staggered with the pulse extrusion mechanism 5 to avoid mutual interference between the heating component and the pulse extrusion mechanism 5. When the lower mold 2 and the upper mold 3 are closed, the upper mold 3 moves downward, and the connecting shaft 502 is inserted into the upper mold 3 and plugged into the support plate 501 inside the upper mold 3; the connecting shaft 502 rotates, and the connecting shaft 502 can drive the upper mold 3 and the support plate 501 inside the lower mold 2 to rotate, and the support plate 501 rotates inside the movable cavity 7, and the arc plate 503 rotates with the support plate 501. During the rotation of the arc plate 503, the arc plate 503 and the first push rod 504 are in staggered contact and support. When the arc plate 503 contacts the first push rod 504, as the arc plate 503 rotates, the arc plate 503 gradually pushes the first push rod 504 outward, the spring 505 is compressed, and the first push rod 504 gradually extends along the first through groove 8 into the annular vulcanization cavity 4, and the first push rod 504 performs impact extrusion on the inner tube inside the annular vulcanization cavity 4. 503, and the first push rod 504 is retracted and reset, and the first push rod 504 is retracted back to the inside of the first through groove 8. The end of the first push rod 504 located inside the active cavity 7 contacts the outer wall of the other curved plate 503 again, and then the first push rod 504 is pushed outward again. As the support plate 501 continues to rotate, the curved plate 503 is also in a state of continuous rotation, which can realize the intermittent and reciprocating extension and contraction operation of the first push rod 504. The first push rod 504 intermittently and reciprocally impacts and extrudes the surface of the inner tube, which can effectively realize multi-point pulse extrusion treatment on the surface of the inner tube, which can effectively improve the surface rhythmic effect of the inner tube, so that the surface of the inner tube is in a pulse extrusion rhythmic state for vulcanization treatment, and the vulcanization treatment of the inner tube is more uniform, so that the vulcanization treatment effect of the inner tube is better. The servo motor 201 drives the connecting shaft 502 to rotate through the reducer 202 and the coupling 203. The telescopic movement of the hydraulic cylinder 301 drives the upper mold 3 to move up and down, thereby realizing the mold closing and demolding operations of the lower mold 2 and the upper mold 3. When the lower mold 2 and the upper mold 3 are closed, the upper mold 3 moves downward, the connecting shaft 502 is inserted into the second through hole, and the limiting bar 507 moves along the second limiting groove until the connecting shaft 502 enters the movable cavity 7. As the upper mold 3 continues to move downward, the connecting shaft 502 is inserted into the inner side of the first through hole 506 of the support plate 501, and the limiting bar 507 is inserted into the inner side of the first limiting groove, thereby realizing the limiting connection between the connecting shaft 502 and the support plate 501 inside the upper mold 3. At this time, the upper mold 3 and the lower mold 2 are closed, the connecting shaft 502 rotates, and the connecting shaft 502 drives the support plate 501 inside the upper mold 3 to rotate through the limiting bar 507 and the first limiting groove; The mounting frame 601 in the inflation and exhaust assembly 6 connects and supports the inflation pump 602, the inflation interface 603 and the exhaust interface 604. The inflation pump 602 is externally connected to an air compressor, and the exhaust interface 604 is externally connected to an exhaust device. The inflation pump 602 is turned on to inflate the inner tube through the inflation interface 603, and then the air pressure detector on the inflation pump 602 is used to display data to determine whether the inner tube is leaking. When the inner tube shows no leakage, the inner tube is vacuumed through the exhaust interface 604 and then packaged. When the inner tube shows leakage, the inner tube inflation inspection fails and is collected and processed uniformly, and then rework is performed or the parts are directly disassembled and re-processed.

When the toggle rod 513 contacts the end of the first connecting rod 510, as the toggle rod 513 rotates, the first connecting rod 510 moves along the outer wall of the toggle rod 513, the toggle rod 513 gradually pushes the end of the first connecting rod 510 downward, the torsion spring 515 is compressed, and the first connecting rod 510 pushes the second push rod 512 through the second connecting rod 511, so that the second push rod 512 extends outward along the second through slot 9, and the second push rod 512 enters the annular vulcanization cavity 4 to impact and extrude the inner tube. When the first connecting rod 510 is retracted, the second push rod 512 is pulled back into the second through groove 9 by the first connecting rod 510 through the second connecting rod 511. As the toggle rod 513 continues to rotate, the end of the first connecting rod 510 contacts the outer wall of the other toggle rod 513 again, and then the second push rod 512 is pushed outward again. As the support plate 501 continues to rotate, the toggle rod 513 is also in a state of continuous rotation, which can realize the intermittent and reciprocating extension and contraction operation of the second push rod 512. The second push rod 512 intermittently and reciprocally impacts and extrudes the surface of the inner tube, which can effectively realize multi-point pulse extrusion treatment on the surface of the inner tube, which can effectively improve the surface rhythmic effect of the inner tube, so that the surface of the inner tube is in a pulse extrusion rhythmic state for vulcanization treatment, and the vulcanization treatment of the inner tube is more uniform, so that the vulcanization treatment effect of the inner tube is better. The first push rod 504 performs a multi-point pulse extrusion process on the inner tube inside the annular vulcanization chamber 4 in the horizontal direction, and the second push rod 512 performs a multi-point pulse extrusion process on the inner tube inside the annular vulcanization chamber 4 in the vertical direction. The first push rod 504 and the second push rod 512 cooperate with each other to further improve the multi-point pulse extrusion process effect on the inner tube, and the pulse extrusion rhythm of the inner tube surface is more uniform, further improving the vulcanization process effect of the inner tube; By designing the position, size or number of the toggle rod 513 and the curved plate 503 (the specific design requires rigorous data calculation and mechanical demonstration), the ejection time of the first push rod 504 and the second push rod 512 can be designed, so that the first push rod 504 and the second push rod 512 can simultaneously perform impact extrusion processing on the inner tube, or can also perform impact extrusion processing on the inner tube in a cross-direction.
