Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, and in particular to a vulcanizing machine for producing rubber inner tubes. Background Technology

[0002] Inner tubes, also known as tire tubes, are circular elastic tubes with valves used to maintain tire pressure. The valves are used to inflate the tubes and maintain a certain pressure inside. Inner tubes should have good airtightness, heat resistance, elasticity, aging resistance, and minimal permanent deformation. They are generally made of butyl rubber. Inner tubes are air-bearing containers used for inflation and vibration damping, and are auxiliary air-bearing containers used inside the tires of automobiles, motorcycles, bicycles, and rickshaws.

[0003] In the processing of rubber inner tubes, a vulcanizing machine is needed to cure the rubber on the inner tube. The vulcanizing machine can automatically open and close the mold. As the machinery for vulcanizing inner tubes, the vulcanizing machine heats and pressurizes the mold. The mold mainly consists of a base, transmission mechanism, beam, pressure cap, control panel, and steam pipes. Existing vulcanizing machines use hydraulic cylinders to drive the upper and lower molds to align during vulcanization, creating a complete vulcanization mold space. When the hydraulic cylinders reverse and demold, factories typically use manual labor to pry the vulcanized inner tube out of the lower mold and remove it manually. However, the vulcanization process in current technology involves heating. When manually removing the inner tube, personnel are in direct contact with the high temperature, and manual removal is inefficient. The process of removing the vulcanized inner tube and then inserting it into the next inner tube is extremely laborious, resulting in low production efficiency. Utility Model Content

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] according to Figure 1-6 As shown, a vulcanizing machine for producing rubber inner tubes includes a vulcanizing machine body 1. A first drive mechanism 2 is mounted on the right side of the vulcanizing machine body 1 in a liftable manner. The first drive mechanism 2 includes a mounting base 21, which is movably mounted on the vulcanizing machine body 1. A moving plate 27 is movably mounted on the mounting base 21. A support arm 28 is fixedly mounted on the moving plate 27 by bolts. A mounting frame 29 is fixedly mounted on the side of the support arm 28 near the vulcanizing machine body 1. A gripping mechanism 4 is fixedly mounted on the mounting frame 29. A second drive mechanism 3, identical to the first drive mechanism 2, is mounted on the left side of the vulcanizing machine body 1. The second drive mechanism 3 is a mirror image of the first drive mechanism 2. The gripping mechanism 4 includes a positioning ring 41. A groove 411 is formed at the bottom of the positioning ring 41. A locking platform 412 is provided at the bottom end of the groove 411. A top block 42 is movably mounted on the top of the groove 411. An ejection assembly is mounted on the mounting frame 29. The ejection assembly is used to drive the top block 42 to move. A placement seat 5 is mounted on the front side of the vulcanizing machine body 1.

[0023] In the above specific embodiment, the inner tube to be processed is placed on the placement seat 5 in advance. The gripping mechanism 4 connected to the first drive mechanism 2 grips and transports the inner tube on the placement seat 5 into the vulcanizing machine body 1. The gripping mechanism 4 connected to the second drive mechanism 3 takes the vulcanized inner tube out of the vulcanizing machine body 1. When gripping the inner tube, the moving plate 27 drives the positioning ring 41 to move directly above the inner tube. Then, the mounting seat 21 drives the positioning ring 41 to descend. The locking platform 412 at the bottom of the groove 411 protrudes outward. When the positioning ring 41 descends to grip the inner tube, the side of the inner tube is locked by the locking platform 412, thereby fixing the inner tube on the positioning ring 41.

[0024] In this embodiment, the ejection assembly includes an ejection cylinder 43, which is fixedly installed on the end of the mounting bracket 29 away from the support arm 28. A drive plate 44 is fixedly installed on the power output shaft of the ejection cylinder 43. Several sets of connecting rods 45 are fixedly installed on the bottom of the drive plate 44 near the edge. The connecting rods 45 are slidably installed on the positioning ring 41. The bottom end of the connecting rod 45 is fixedly connected to the top block 42. When the positioning ring 41 drives the inner tube to be delivered to the position, the ejection cylinder 43 drives the drive plate 44 to descend, causing the top block 42 to move downward and eject the inner tube from the groove 411, so that the inner tube is detached from the positioning ring 41.

[0025] In this embodiment, a first U-shaped groove 413 is provided on the inner sidewall of the positioning ring 41, and a clamping assembly is provided on the inner side of the first U-shaped groove 413. The clamping assembly includes a bidirectional cylinder 46, which is fixedly mounted on a cylinder frame 47. The cylinder frame 47 is fixedly mounted on the top of the positioning ring 41. Claws 48 are fixedly mounted on both sides of the power output end of the bidirectional cylinder 46. The two sets of claws 48 are mirror images of each other. When gripping the inner tube, the bidirectional cylinder 46 drives the two sets of claws 48 to move closer to each other, so that the claws 48 clamp the valve, thereby fixing the inner tube and preventing the inner tube from shifting during the transportation process.

[0026] In this embodiment, a support frame 6 is fixedly installed at the bottom of the placement seat 5. The support frame 6 is fixedly installed on the vulcanizing machine body 1 by bolts. A placement groove 51 is opened at the top of the placement seat 5. The placement groove 51 is an annular structure that matches the inner tube. A second U-shaped groove 52 is opened on the inner side wall of the placement seat 5, which corresponds to the position of the first U-shaped groove 413. During processing, the workers put the inner tube into the placement groove 51 in advance for fixation and embed the air nozzle into the second U-shaped groove 52.

[0027] In this embodiment, guide rail slider assemblies 22 are installed on both the left and right side walls of the vulcanizing machine body 1. Mounting seats 21 are installed on the guide rail slider assemblies 22. The guide rail slider assemblies 22 support and guide the mounting seats 21. A first cylinder 23 is provided on the upper side of the mounting seats 21. The first cylinder 23 is fixedly installed on the vulcanizing machine body 1 by a bracket. The power output end of the first cylinder 23 is fixedly connected to the mounting seats 21. The first cylinder 23 drives the mounting seats 21 to rise and fall on the vulcanizing machine body 1. After the mounting seats 21 fall, the gripping mechanism 4 performs the action of gripping or placing the inner tube.

[0028] In this embodiment, guide rods 24 are fixedly installed at both the upper and lower ends of the mounting base 21 via brackets. A slide block 25 is slidably installed on the guide rod 24. The slide block 25 is fixedly installed on the moving plate 27. A second cylinder 26 is fixedly installed at the end of the mounting base 21 away from the support arm 28. The power output end of the second cylinder 26 is fixedly connected to the moving plate 27. When the first cylinder 23 drives the mounting base 21 to rise, the second cylinder 26 starts. The second cylinder 26 drives the moving plate 27 to move along the guide rod 24 to realize the delivery of the inner tube.

[0029] In this embodiment, a lower mold 11 is fixedly installed inside the vulcanizing machine body 1. A pressure cover 12 is provided above the lower mold 11. An upper mold 13 is fixedly installed at the bottom of the pressure cover 12. A hydraulic cylinder 14 is fixedly installed at the top of the vulcanizing machine body 1. The power output end of the hydraulic cylinder 14 is fixedly connected to the pressure cover 12. Several sets of smooth rods 15 are fixedly installed at the top edge of the pressure cover 12. The smooth rods 15 are slidably installed on the vulcanizing machine body 1.

[0030] In use, the operator installs the inner tube to be vulcanized onto the placement seat 5. Then, the push rod of the first cylinder 23 on the right side of the vulcanizing machine body 1 extends, driving the mounting seat 21 to descend, causing the inner tube to be snapped and fixed onto the positioning ring 41. The bidirectional cylinder 46 then drives the gripper 48 to hold the air nozzle. Afterwards, the first cylinder 23 resets, and the mounting seat 21 drives the positioning ring 41 to rise, thus lifting the inner tube from the placement seat 5. Then, the push rod of the second cylinder retracts, causing the positioning ring 41 to move the inner tube above the lower mold 11. After the first cylinder 23 drives the mounting seat 21 to descend again, the bidirectional cylinder... The 46 drive gripper 48 releases the air nozzle, and the ejector cylinder 43 drives the ejector block 42 to eject the inner tube from the positioning ring 41, so that the inner tube is transported into the lower mold 11. Then the first cylinder 23 and the second cylinder 26 are reset in sequence to prepare for the subsequent loading operation. After the loading is completed, the mold is closed under the drive of the hydraulic cylinder 14 to vulcanize the inner tube. After vulcanization is completed, the gripping mechanism 4 connected to the second drive mechanism 3 takes out the vulcanized inner tube from the rear side of the vulcanizing machine body 1. The above steps are repeated to carry out the batch production of inner tubes. Therefore, the automatic loading and unloading of inner tubes is realized, which is conducive to improving production efficiency.

[0031] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
