Description

Technical Field

[0001] This utility model relates to the field of inflatable ball processing technology, specifically to a vulcanization device for vulcanized rubber used in the inner liner of inflatable balls. Background Technology

[0002] Vulcanized rubber is an essential material in the processing of inflatable balls, typically used to make the inner lining of these balls. Vulcanization equipment mainly includes a vulcanizing machine and a heating device. The vulcanizing machine usually consists of a mold, a heating plate, and a compression device. The working principle is that the rubber mixture is placed in the mold, and heat is provided by the heating plate, causing the vulcanizing agent to chemically react with the rubber. This process causes the rubber molecular chains to form a cross-linked structure, thereby improving the rubber's strength, elasticity, and durability, and enhancing the quality of subsequent ball processing.

[0003] A rubber vulcanizing device disclosed in Chinese Patent Publication No. CN108908811A includes a transmission adjustment assembly with an adjustable drive wheel and a pressure rod assembly for pressing the material at the feeding end. The pressure rod assembly has a pressure rod to press the upper side of the rubber product to prevent deformation, and the position of the pressure rod assembly moves synchronously with the adjustment of the drive wheel, making operation convenient. An exhaust mechanism is provided at the discharge end, in which the exhaust hood can be raised and lowered according to the product height to ensure exhaust effect. The exhaust hood and exhaust channel are connected by a bellows cover to achieve height adjustment while preventing exhaust gas from overflowing. However, the vulcanizing device has low overall applicability and cannot replace and adjust the mold and heating components according to the actual specifications of inflatable ball liner, which may result in incomplete vulcanization of the inflatable ball liner, affecting the subsequent processing quality of the inflatable ball liner. Utility Model Content

[0004] The purpose of this invention is to provide a vulcanization device for vulcanized rubber used in the inner liner of inflatable balls, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vulcanizing device for vulcanized rubber used in inflatable ball liner, comprising a workbench, a conveyor belt installed inside the top of the workbench, movable doors installed on both sides of the outside of the workbench, limit mechanisms provided on both sides of the inside of the workbench, a mold body installed at the top of the conveyor belt, a vulcanizing chamber installed in the middle of the top of the workbench, dustproof belts installed on both sides of the vulcanizing chamber, a collection chamber installed on one side of the top of the vulcanizing chamber, a linear motor installed on one side of the inside of the vulcanizing chamber, a cooling fan installed on one side of the linear motor, hydraulic rods installed on both sides of the top of the vulcanizing chamber, mounting bases fixedly connected to the bottom ends of the hydraulic rods, an installation mechanism provided in the middle of the inside of the mounting base, a pressure plate installed on the outside of the mounting base, and a heating plate installed in the middle of the bottom end of the pressure plate.

[0006] Preferably, the limiting mechanism includes a locking block that is movably connected to both sides inside the worktable, a first movable plate that is fixedly connected to one side of the locking block, and a spring that is fixedly connected to one side of the first movable plate.

[0007] Preferably, the mold body has slots on both sides for engaging with the card blocks, a positioning groove around the top of the mold body, and a positioning rod that engages with the positioning groove is fixedly connected around the bottom of the pressure plate.

[0008] Preferably, an air extractor is installed on one side of the bottom of the collection chamber, and an air suction chamber is fixedly connected to the bottom of the air extractor.

[0009] Preferably, the mounting mechanism includes a rotatable handle rotatably connected to the middle position of the top of the mounting base, a gear rotating inside the mounting base is fixedly connected to the bottom end of the rotatable handle, and a torsion spring fixedly connected to the middle position of the top of the gear and fixedly connected to the mounting base at its top end.

[0010] Preferably, the gear is meshed with a rack on both sides, a second movable plate is fixedly connected to one side of the rack, an insert block is fixedly connected to one side of the second movable plate, and slots for inserting into the insert block are provided on both sides inside the top of the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This vulcanizing equipment for inflatable ball liner uses vulcanized rubber. The rubber mixture is placed inside the mold body, and with the heating of the bottom heating plate of the pressure plate, the vulcanization of the inflatable ball liner can be fully carried out. When the pressure plate and heating plate need to be replaced according to different inflatable ball liner requirements, the handle on the mounting base is turned, which drives the gear to rotate. At this time, the gear drives the second movable plate and the insert block to move through the racks on both sides. When the insert block is pulled out from the slot on the pressure plate, the pressure plate can be quickly replaced, thus allowing for rapid adjustment according to the actual size and specifications of the inflatable ball liner. The modular design improves the overall applicability of the vulcanizing equipment and facilitates the inspection and maintenance of the vulcanizing equipment.

[0013] 2. This vulcanizing equipment for inflatable ball liner uses vulcanized rubber. Multiple sets of locking blocks are installed on both sides of the workbench. When the conveyor belt pushes the mold body to directly below the pressure plate, the locking blocks on both sides of the workbench can engage with the locking grooves on the mold body, thus completing the auxiliary limiting work of the mold body. Furthermore, multiple sets of positioning rods are installed around the bottom of the pressure plate, corresponding to the positioning grooves on the mold body. Therefore, when the hydraulic rod pushes the mounting base and pressure plate downwards, the positioning rods at the bottom of the pressure plate can stably insert into the positioning grooves at the top of the mold body, ensuring the overall stability of the vulcanization process for the inflatable ball liner.

[0022] Example 1: A vulcanizing device for vulcanized rubber used in the inner liner of inflatable balls includes a workbench 1, a conveyor belt 101 installed inside the top of the workbench 1, movable doors 102 installed on both sides of the outside of the workbench 1, limit mechanisms 2 provided on both sides inside the workbench 1, a mold body 3 provided at the top of the conveyor belt 101, a vulcanizing chamber 4 installed in the middle of the top of the workbench 1, and dustproof belts 401 installed on both sides of the vulcanizing chamber 4. The mold body 3 can be moved by the conveyor belt 101, and the dustproof belts 401 can reduce the leakage of irritating gases inside the vulcanizing chamber 4.

[0023] A collection chamber 5 is installed on one side of the top of the vulcanizing chamber 4. A linear motor 6 is installed on one side inside the vulcanizing chamber 4. A cooler 601 is installed on one side of the linear motor 6. When the linear motor 6 is started, it can drive the cooler 601 to reciprocate inside the vulcanizing chamber 4. At the same time, the cooler 601 can make the cooling gas cool the mold quickly and evenly, preventing uneven rubber shrinkage caused by sudden temperature drop.

[0024] Hydraulic rods 7 are installed on both sides of the top of the vulcanizing chamber 4. The bottom of the hydraulic rods 7 is fixedly connected to the mounting base 8. The mounting mechanism 9 is set in the middle of the inside of the mounting base 8. The pressure plate 10 is installed on the outside of the mounting base 8. The heating plate 12 is installed in the middle of the bottom of the pressure plate 10. When the hydraulic rods 7 are activated, they can push the mounting base 8 and the pressure plate 10 to move downward. At this time, the heating plate 12 at the bottom of the pressure plate 10 can compress and heat the rubber mixture in the mold body 3.

[0025] A vacuum pump 501 is installed on one side of the bottom of the collection chamber 5. The bottom of the vacuum pump 501 is fixedly connected to a suction chamber 502. When the vacuum pump 501 is started, the irritating gas generated by sulfidation can be sucked into the interior of the collection chamber 5 through the suction chamber 502.

[0026] The mounting mechanism 9 includes a handle 901 rotatably connected to the middle of the top of the mounting base 8. A gear 902, rotating inside the mounting base 8, is fixedly connected to the bottom of the handle 901. A torsion spring 903, whose top is fixedly connected to the mounting base 8, is fixedly connected to the middle of the top of the gear 902. A rack 904 meshes with both sides of the gear 902. A second movable plate 905 is fixedly connected to one side of the rack 904. An insert block 906 is fixedly connected to one side of the second movable plate 905. The pressure plate 10 has two sides inside its top. A slot 1001 is provided for insertion of the insert 906. Rotating the throttle 901 can drive the gear 902 to rotate. At this time, the gear 902 can push the racks 904 on both sides, and the racks 904 can drive the insert 906 to move through the second movable plate 905. A torsion spring 903 is installed at the top of the gear 902 to perform the reset work after the throttle 901 and the gear 902 are rotated. When the insert 906 is inserted into the slot 1001 on the pressure plate 10, the connection and assembly of the mounting base 8 and the pressure plate 10 can be completed.

[0027] Example 2 differs from Example 1 mainly in that:

[0028] A vulcanizing device for vulcanized rubber used in the inner liner of an inflatable ball includes a limiting mechanism 2 comprising a locking block 201 movably connected to both sides inside a workbench 1. A first movable plate 202 is fixedly connected to one side of the locking block 201, and a spring 203 is fixedly connected to one side of the first movable plate 202. When the locking block 201 is subjected to force, the spring 203 can be compressed by the first movable plate 202. When the locking block 201 is released from force, the locking block 201 can be reset by the reaction force of the compressed spring 203 through the first movable plate 202.

[0029] The mold body 3 has slots 301 on both sides that engage with the locking block 201. The top of the mold body 3 has a positioning groove 302 around its perimeter. The bottom of the pressure plate 10 has a positioning rod 11 fixedly connected around its perimeter that engages with the positioning groove 302. When the locking block 201 engages with the slot 301 on the mold body 3, the mold body 3 can be auxiliaryly limited. At the same time, the positioning rod 11 at the bottom of the pressure plate 10 is inserted into the positioning groove 302 at the top of the mold body 3, which can increase the stability of the connection between the mold body 3 and the pressure plate 10. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] In this embodiment of the application, the mold body 3 containing the rubber mixture is placed on the conveyor belt 101 at the top of the workbench 1. When the conveyor belt 101 is activated, it can push the mold body 3 to move. When the mold body 3 moves to the middle position at the top of the conveyor belt 101, the locking blocks 201 on both sides inside the workbench 1 can be locked into the locking grooves 301 on the mold body 3. At this time, the hydraulic rod 7 is activated and can push the pressure plate 10 downward through the mounting base 8. At this time, the heating plate 12 at the bottom of the pressure plate 10 can evenly heat the rubber mixture in the mold body 3 and cause the vulcanizing agent to react chemically with the rubber. After vulcanization, the pressure plate 10 is reset by the hydraulic rod 7. At this time, the linear motor 6 is activated and can drive the air cooler 601 to reciprocate at the top of the mold body 3. The air cooler 601 can quickly and evenly cool the mold with cooling gas, and the vulcanized rubber material in the mold body 3 can be quickly discharged by the activation of the conveyor belt 101.
