Description

Technical Field

[0001] This utility model relates to the field of ball manufacturing and processing technology, specifically to a safety device for vulcanization of the inner tube of a ball. Background Technology

[0002] Vulcanization is a process in which rubber macromolecules react chemically with sulfur as a crosslinking agent under heating, forming a three-dimensional network structure. The rubber after vulcanization is called vulcanized rubber. Further processing on this basis can yield shaped rubber products with practical value, such as the inner tube of a ball and tires.

[0003] Currently, most vulcanizing equipment for rubber ball tires consists of hemispherical vulcanizing heating molds assembled from upper and lower parts. The separation and merging of the two molds during pressurization are achieved using hydraulic rods and screw structures respectively. However, due to the structural limitations of existing equipment, the screw structure is often directly exposed to the processing environment. After prolonged use, the self-locking ability of the screw structure gradually decreases due to factors such as dust adhesion in the processing environment and its own reciprocating meshing wear, posing certain safety hazards. Utility Model Content

[0004] This invention provides a safety device for the vulcanization of a rubber ball's inner tire, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a safety device for vulcanizing a rubber ball tire, comprising a workbench, a fixed vulcanizing heating mold, a moving vulcanizing heating mold, a linkage plate, and a support on the top of the workbench. The end of the linkage plate is engaged with the side of the support, and the linkage plate is fixed to the top of the moving vulcanizing heating mold. A first hydraulic rod, fitted inside the workbench, is connected to the bottom of the support. A clearance groove is provided at the bottom of the end of the linkage plate to engage and limit the output end of the first hydraulic rod. One end of a screw passes through the support and is threadedly connected to an internally threaded cylinder installed on the top of the support, and the other end of the screw... One end is clamped to a positioning sleeve fixed to the top of the linkage plate. The top of the bracket has a semi-open groove and a through hole. The semi-open groove is fitted with a composite guide sleeve that can be sleeved with the screw and two second hydraulic rods. The composite guide sleeve is composed of two front-to-back first arc plates and two left-to-right second arc plates. The second arc plates are clamped between the two first arc plates. The first arc plates are fixedly sleeved in the semi-open groove. The output ends of the two second hydraulic rods are respectively connected to the middle of the two second arc plates and can enable the two second arc plates to clamp the screw close together.

[0006] Preferably, a frame plate aligned with the semi-open groove is fixed to the front surface of the top of the bracket, and a sealing plate is fitted inside the front end of the frame plate.

[0007] Preferably, a hexahedral rod is fixed to the other end of the screw, and the surface of the screw is coated with a wear-resistant coating.

[0008] Preferably, the composite guide sleeve has an annular groove in its middle. The annular groove consists of four arc-shaped grooves, which are distributed on the inner walls of the middle of the two first arc-shaped plates and the two second arc-shaped plates, forming a closed ring around the center of the through hole. A dust collection component is installed inside the semi-open groove. The output structure of the dust collection component is installed inside a first arc-shaped plate and communicates with the arc-shaped groove inside it. The dust collection component can automatically perform negative suction cleaning of dust on the screw surface through the annular groove.

[0009] Preferably, the vacuuming assembly includes a duct, a semi-open cylinder, a composite filter component, and an air pump. The duct, as the output structure of the vacuuming assembly, is installed between the corresponding first arc-shaped plate and one side of the semi-open cylinder. The composite filter component is fitted inside the semi-open cylinder and forms several filter spaces inside the semi-open cylinder. The input end of the air pump is fitted inside the other side of the semi-open cylinder, and the output end of the air pump passes through the semi-open groove and extends to the top outer side of the bracket.

[0010] Preferably, the composite filter component includes a support frame plate, and a plurality of filter screens are sequentially installed inside the support frame plate. Temporary storage spaces are provided at the bottom of two adjacent filter screens. A groove is provided in the front end of the support frame plate, and the front end structure of the support frame plate is snapped through the sealing plate and extends to the outer side of the top front end of the bracket.

[0026] 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.

[0027] Please see Figures 1-5 A safety device for vulcanizing a ball-shaped tire includes a workbench 1. A fixed vulcanizing heating mold 2, a movable vulcanizing heating mold 3, a linkage plate 4, and a support 5 are mounted on the top of the workbench 1. The end of the linkage plate 4 is engaged with the side of the support 5, and the linkage plate 4 is fixed to the top of the movable vulcanizing heating mold 3. A first hydraulic rod 7, fitted inside the workbench 1, is connected to the bottom of the support 5 via a transmission connection. A clearance groove 6 is provided at the bottom of the end of the linkage plate 4 to engage and limit the output end of the first hydraulic rod 7. One end of a screw 9 passes through the support 5 and is threadedly connected to an internally threaded cylinder 8 mounted on the top of the support 5. The other end of the screw 9 is engaged with a device fixed to the linkage plate 1. The positioning sleeve 10 at the top of the moving plate 4 and the bracket 5 have a semi-open groove and a through hole in the top. The semi-open groove is fitted with a composite guide sleeve that can be sleeved with the screw 9 and two second hydraulic rods 13. The composite guide sleeve is composed of two front and rear opposite first arc plates 11 and two left and right opposite second arc plates 12. The second arc plates 12 are snapped between the two first arc plates 11. The first arc plates 11 are fixedly sleeved in the semi-open groove. The output ends of the two second hydraulic rods 13 are respectively connected to the middle of the two second arc plates 12 and can enable the two second arc plates 12 to clamp the screw 9 in close proximity.

[0028] A frame plate 19 aligned with the semi-open groove is fixed to the top front surface of the bracket 5. A sealing plate 20 is fitted inside the front end of the frame plate 19. When the frame plate 19 and the sealing plate 20 are used together, they can seal and protect the components inside the semi-open groove, preventing unauthorized personnel from contacting them and improving safety. A hexahedral rod is fixed to the other end of the screw 9. When the existing socket wrench is used in combination with the hexahedral rod, the screw 9 can be turned with less effort, reducing the difficulty of operation. The surface of the screw 9 is coated with a wear-resistant coating, which improves the wear resistance of the screw 9 during subsequent reciprocating meshing.

[0029] In use, after vulcanization is completed, the first hydraulic rod 7 drives the combination of the moving vulcanizing heating mold 3 and the linkage plate 4 to move automatically upward, so that the moving vulcanizing heating mold 3 and the fixed vulcanizing heating mold 2 are automatically separated. Then, in order to further expand the clearance space, the existing socket wrench and the hexahedral rod set on the other end of the screw 9 are fitted together. After completion, the socket wrench is turned so that the socket wrench drives the screw 9 to rotate synchronously through the hexahedral rod. During the rotation of the screw 9, due to the locking and limiting of the positioning sleeve 10, the combination of the moving vulcanizing heating mold 3 and the linkage plate 4 will be further pulled and lifted upward until the combination of the moving vulcanizing heating mold 3 and the linkage plate 4 is lifted to a suitable height.

[0030] After the assembly formed by the waiting vulcanizing heating mold 3 and the linkage plate 4 comes to a stop, in order to prevent the screw 9 from accidentally moving downward due to increased wear, the two second hydraulic rods 13 are activated. The output ends of the two second hydraulic rods 13 respectively drive the corresponding second arc plate 12 to clamp and limit the screw 9, thereby improving the safety, reliability and self-locking performance of the screw 9 during use.

[0031] Please see Figures 3-8 The composite guide sleeve has an annular groove 14 in the middle. The annular groove 14 is composed of four arc-shaped grooves. These four arc-shaped grooves are distributed on the inner walls of the middle of the two first arc-shaped plates 11 and the two second arc-shaped plates 12, and form a closed ring around the center of the through hole. A dust collection component is installed in the semi-open groove. The output structure of the dust collection component is installed inside a first arc-shaped plate 11 and communicates with the arc-shaped groove inside it. The dust collection component can automatically perform negative suction cleaning of dust on the surface of the screw 9 through the annular groove 14.

[0032] The vacuuming assembly includes a duct 15, a semi-open cylinder 16, a composite filter component 17, and an air pump 18. The duct 15, as the output structure of the vacuuming assembly, is installed between the corresponding first arc plate 11 and one side of the semi-open cylinder 16. The composite filter component 17 is fitted inside the semi-open cylinder 16 and forms several filter spaces inside the semi-open cylinder 16. The input end of the air pump 18 is fitted inside the other side of the semi-open cylinder 16, and the output end of the air pump 18 passes through the semi-open groove and extends to the top outer side of the bracket 5 to ensure the smooth effect of reciprocating negative suction pump air.

[0033] The composite filter component 17 includes a support frame plate 171, inside which several filter screen plates 172 are sequentially installed. Temporary storage spaces are provided at the bottom of two adjacent filter screen plates 172 to temporarily retain the filtered impurities. A groove is provided in the front end of the support frame plate 171 to provide space for subsequent pinching. The front end structure of the support frame plate 171 is snapped through the sealing plate 20 and extends to the outer side of the top front end of the bracket 5. The surface of the sealing plate 20 is provided with a positioning component for pressing and limiting the front end structure of the support frame plate 171.

[0034] The positioning components include an external threaded cylinder 23 and a limiting sleeve 21. Several L-shaped top pressure rods 22 are installed inside the limiting sleeve 21. The external threaded cylinder 23 is fixed to the surface of the sealing plate 20, and the inner side of the rear end of the limiting sleeve 21 is threadedly connected to the front end of the external threaded cylinder 23. After the limiting sleeve 21 and the external threaded cylinder 23 have reached their maximum stroke of thread engagement, the L-shaped top pressure rods press and limit the front end of the support frame plate 171.

[0035] During use, considering the issue of dust adhering to the surface of screw 9 in the operating environment, which accelerates wear during subsequent reciprocating engagement, a dust collection component is used to clean the surface of screw 9 using negative suction. The specific principle is as follows:

[0036] During the spiral movement of the screw 9, the suction pump 18 is started simultaneously. The dust adhering to the surface of the screw 9 is negatively attracted to the interior of the semi-open cylinder 16 through the channel with filtration function formed by the semi-open cylinder 16, the composite filter component 17, the conduit 15 and the annular groove 14. Then, under the filtration of multiple filter screens 172 inside the composite filter component 17 and the action of gravity, the dust will be temporarily stored in the temporary storage space formed between the bottoms of two adjacent filter screens 172. This ensures the cleanliness of the screw 9 surface, reduces the wear rate of continuous meshing, and improves the service life of the screw 9.

[0037] After the composite filter element 17 has been used for a certain period of time, in order to maintain the continuous high-efficiency filtration performance of the composite filter element 17, the composite filter element 17 can be disassembled and cleaned. The specific operation is as follows:

[0038] Tighten the limiting sleeve 21 to cause the limiting sleeve 21 to drive the multiple L-shaped top pressure rods 22 to separate from the external threaded cylinder 23. This releases the limiting sleeve 21 and the multiple L-shaped top pressure rods 22 from limiting the front end of the composite filter component 17. After completion, pinch the groove and pull the entire composite filter component 17 out from the inside of the semi-open cylinder 16. Pour out and clean the dust inside the composite filter component 17. Then, reinstall the composite filter component 17 into the inside of the semi-open cylinder 16, and then reinstall the limiting sleeve 21 and the multiple L-shaped top pressure rods 22 to limit and protect the front end of the composite filter component 17 again.

[0039] Please see Figure 7 The top surface of the bracket 5 is fixed with a combined screw sleeve, and the external thread of the combined screw sleeve is connected to a dustproof cylinder 24 that can be fitted onto the output end of the suction pump 18. A dustproof filter is fixedly nested inside the top of the dustproof cylinder 24.

[0040] When in use, considering that external dust can easily fall into the output port of the suction pump 18 when it is not in use, the dustproof cylinder 24 and dustproof filter are used to protect the output port of the suction pump 18 from dust.
