Description

Technical Field

[0001] The invention belongs to the technical field of vulcanization equipment, in particular to a multi-station automatic vulcanization system. Background Art

[0002] Vulcanization is a chemical reaction process that typically involves reacting rubber or other polymers with a vulcanizing agent under certain conditions to cause cross-linking, thereby improving the material's strength, wear resistance, and aging resistance. Vulcanization can be achieved through hot or cold vulcanization.

[0003] Hot vulcanization involves mixing a polymer with a vulcanizing agent and then heating it to a certain temperature. This decomposition of the vulcanizing agent generates free radicals, which in turn trigger a crosslinking reaction between the polymer chains, forming a crosslinked structure. This crosslinking structure improves the strength and wear resistance of the polymer, making it more suitable for use in rubber products. Vulcanization is an important process widely used in rubber products, plastics, coatings, adhesives, and other fields to improve material performance and extend service life.

[0004] In the past, many steps of the vulcanization system required manual assistance during operation, resulting in low efficiency, low output, and high costs. The current multi-station automatic vulcanization system does not require manual intervention from the loading and transfer of the skeleton and rubber materials to the vulcanization unit to the completion of vulcanization and the unloading of the product. This fully automated multi-station vulcanization method not only improves production efficiency but also reduces labor costs. Summary of the Invention

[0035] The usage status of the present invention is: the multi-station automatic vulcanization system adopts a pushing and lifting mechanism 3 to load the skeleton to the skeleton conveyor line. The skeleton conveyor line is provided with a sensor, a pushing cylinder, two dividing cylinders 39, a wind knife device 38, a laser rangefinder 37 and a slide cylinder 36. The sensor is used to detect whether the skeleton is overlapping. If overlapping occurs, the pushing cylinder 391 pushes the skeleton into the blanking slide 33 and the elevator 31 loads it for the second time. The dividing cylinder 39 is used to separate the skeleton so that the laser rangefinder 37 can detect the front and back of the skeleton. If the skeleton is on the back, the wind knife device 38 blows the skeleton into the blanking slide 33. The slide cylinder 36 drives the block to position the skeleton for easy grasping by the transfer mechanism 5.

[0036] The rubber blocks cut out by the rubber preforming extruder will fall into the weighing mechanism 44 below it (a lifting cylinder is provided below the weighing mechanism 44 to drive the weighing load plate to lift and lower for material receiving). The weight of the rubber blocks is screened according to the set threshold value. The rubber blocks with qualified weight are pushed to the rubber block conveying line by the pushing mechanism 45, and the rubber blocks with unqualified weight are pushed to the rubber block NG slide by the pushing cylinder 2 43; the rubber block conveying line is provided with four buffer cylinders 46, a manual slide 2 48 and a positioning cylinder 47. The buffer cylinder 46 is used to separate the rubber blocks so that the rubber blocks arrive at the specified positions in sequence. The manual slide 2 48 is used to adjust the position of the rubber material stopper mounting plate. The positioning cylinder 47 drives the rubber material stopper to position the rubber block for easy grabbing by the transfer mechanism 5.

[0037] The transfer mechanism 5 is driven by a servo motor 52 and a gear is matched with a fixed rack to realize the lateral movement of the entire mechanism. The loading and unloading devices are both realized by the servo motor 52 and the electric cylinder 53 to realize the lifting of the mechanism. There are lifting cylinders above the clamping claw mounting plate and the pin 57 mounting plate (the lifting cylinders are used to adjust the position height when taking the skeleton and the rubber block to avoid interference at the same horizontal height when taking the material). The loading mechanism is composed of a three-claw cylinder 55 to grab the skeleton, and the pin 57 to pierce the rubber block. The unloading mechanism 7 is composed of an open middle mold clamping claw cylinder 58 to grab the middle mold plate 66.

[0038] The vulcanization mechanism 6 mainly includes a vacuum cover 63, a mold, a heating plate, a heat insulation plate, a hydraulic cylinder 62, and a transfer device 61. The vacuum cover 63 (with pressing cylinders 64 on both sides) is pressed downward by the pressing cylinder 64, and the heating plate heats the mold to reach the vulcanization temperature. The hydraulic cylinder 62 pushes upward to provide pressure for vulcanization. The transfer device 61 mainly includes a gear chain, a push-pull plate, and a motor. The motor drives the gear chain to drive the push-pull plate.

[0039] Vulcanization steps: pre-pressing - exhaust - pressure holding (vulcanization) - mold opening. After the product is vulcanized and the mold is opened, the middle mold is moved to the middle position by the transfer device 61 (a positioning cylinder 47 is provided under the middle mold for mold positioning) and is grabbed by the transfer mechanism 5 and placed on the unloading mechanism 7.

[0040] The unloading mechanism 7 consists of a transfer assembly, a flip assembly (consisting of a flip bracket 75 and a flip fixture 73), a ejection mechanism 71, and a material receiving conveyor line 76. The transfer assembly is used to drive the flip assembly to move between the mold pick-up and placement position and the product ejection position. At the mold pick-up and placement position, the loading and unloading device places the vulcanized middle mold in the flip fixture 73, and then the transfer assembly transfers the flip assembly to the product ejection position. In the flip assembly, the flip fixture 73 is connected to the flip bracket 75 through two seat bearings. The lifting cylinder three 77 drives the rack to rotate the gear to realize the flipping of the flip fixture 73. There are pin mechanisms on both sides of the flip bracket 75, and there are pins to position the flip fixture 73 before and after the mold is flipped. The lifting cylinder four 78 drives the material receiving conveyor line 76 to rise close to the lower end of the flip fixture 73 for easy material receiving. The ejection cylinder 72 drives the pressure block downward to eject the product in the middle mold and drop it onto the material receiving conveyor line 76.
