Description

Technical Field

[0001] This utility model relates to the field of basketball production technology, and more specifically, to a vulcanizing machine for basketball production. Background Technology

[0002] The vulcanizing machine is suitable for the vulcanization and pressing of various rubber and plastic products; it integrates functions such as preheating, automatic gas venting after feeding, pressure vulcanization, timing alarm, automatic mold opening, and product demolding required for rubber vulcanization process.

[0003] Most existing vulcanizing machines used in basketball production can only process one basketball bladder at a time, resulting in low processing efficiency. In addition, the basketball bladder needs to be inflated during processing, and workers need to hold the air pump hose continuously, which causes wrist pain over time, making the equipment less effective.

[0004] A search revealed a Chinese patent, CN219028170U, which discloses a vulcanizing machine for basketball production. This utility model allows workers to process multiple basketball bladders at once by setting multiple heaters and basketball vulcanizing molds on a turntable, greatly improving the efficiency of the device. The turntable rotates and is engaged in a rotating groove on the first fixed plate. The rotation of the turntable drives the multiple basketball vulcanizing molds to rotate, making it convenient for workers to change basketball bladders and making the device easy to use.

[0005] However, in actual use, the vulcanizing machine requires a certain amount of release agent to be applied to the inner surface of the mold before the basketball bladder is vulcanized. This step requires manual spraying by the staff, and repeated spraying is required, which reduces the efficiency of the basketball bladder vulcanization and increases the labor intensity of the staff. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a vulcanizing machine for basketball production to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vulcanizing machine for basketball production includes an operating table. A fixed frame is fixedly connected to the top of the operating table. A hydraulic rod is fixedly connected to the outside of the fixed frame. A pressure plate is fixedly connected to the bottom of the hydraulic rod. Two guide rods are fixedly connected to the top of the pressure plate. The outside of the guide rods is slidably connected to the inside of the fixed frame. Two upper heating molds are fixedly connected to the inside of the guide rods. A base is rotatably connected to the top of the operating table. Multiple lower heating molds are fixedly connected to the top of the base. Heating sleeves are fixedly connected to the inside of both the upper and lower heating molds. Two spraying mechanisms are provided on the upper surface of the operating table. A sealing and inflation mechanism is provided on the outside of the operating table.

[0009] By adopting the above technical solution, the two upper heating molds are moved up and down using hydraulic rods and pressure plates, so that multiple basketball bladders can be vulcanized in pairs in sequence, thereby improving the vulcanization efficiency.

[0010] As a further description of the above technical solution: the spraying mechanism includes a water tank, the outer side of which is fixedly connected to the inner side of the operating table, an inlet pipe fixedly connected to the top of the water tank, a water pump installed on the top of the water tank, a suction pipe fixedly connected to the input end of the water pump and extending to the inner side of the water tank, a water delivery hose fixedly connected to the output end of the water pump, a diverter pipe fixedly connected to one end of the water delivery hose, two dispersing discs fixedly connected to one side of the diverter pipe, three nozzles fixedly connected to the outer side of the dispersing discs, a push block fixedly connected to one side of the dispersing discs, an electric push rod fixedly connected to one side of the push block, and the outer side of the electric push rod fixedly connected to the top of the operating table.

[0011] By adopting the above technical solution, the release agent can be sprayed more evenly on the inner walls of the two heating jackets before vulcanization, so that the basketball bladder can be quickly demolded after vulcanization, reducing the number of work steps for workers to repeatedly apply the release agent.

[0012] As a further description of the above technical solution: multiple toothed grooves are provided on the outer side of the chassis, a fixed plate is fixedly connected to the top of the chassis, a servo motor is fixedly connected to the inner side of the operating table, a gear is fixedly connected to the output end of the servo motor, and one side of the gear meshes with the inner side of the toothed groove.

[0013] By adopting the above technical solution, the chassis can be rotated by the meshing of gears and tooth grooves, which in turn drives the lower hot mold and the air supply pipe to rotate, allowing multiple lower hot molds to be vulcanized in pairs in sequence.

[0014] As a further description of the above technical solution: the sealing inflation mechanism includes an inflation machine, the bottom of which is fixedly connected to the inner side of the operating table, a positioning frame fixedly connected to the output end of the inflation machine, an air supply channel opened on the inner side of the positioning frame, an air supply pipe inserted into the inner side of the air supply channel, two sealing rings fixedly connected to the outer side of the air supply pipe, the outer side of the sealing rings engaging with the inner side of the air supply channel, the inner side of the air supply pipe fixedly connected to the inner side of the fixing plate, an air supply plate fixedly connected to the top of the air supply pipe, multiple connecting pipes connected to the outer side of the air supply plate, and an electrically controlled valve installed on the outer side of the connecting pipe.

[0015] By adopting the above technical solution, the connecting pipe that needs to be ventilated can be opened using an electronically controlled valve, allowing the corresponding two basketball bladders to be inflated, and two sealing rings are used to maintain sufficient sealing when the air supply pipe rotates inside the air supply channel.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up a spraying mechanism, compared with the existing technology, the release agent is sprayed onto the inner surface of the heating jacket of the upper and lower hot molds using a dispersion disc and a spray nozzle. The reciprocating movement of multiple dispersion discs allows the release agent to be sprayed more evenly onto the inner walls of the upper and lower heating jackets, reducing the need for workers to repeatedly spray the release agent. The release agent is also sprayed more comprehensively, improving the vulcanization efficiency and yield of basketball bladders.

[0018] 2. By setting up a sealing inflation mechanism, compared with the existing technology, the sealing ring is used to seal the air supply pipe and air supply channel, so that multiple lower heating molds can maintain good sealing performance during the reciprocating deflection operation, and the vulcanization operation of basketball bladder is smoother and the vulcanization efficiency of basketball bladder is accelerated, so that the vulcanizing machine can perform the vulcanization operation of basketball better.

The outer side of the electric push rod 18 is fixedly connected to the top of the operating table 1. Two water pumps 12 draw out the release agent inside the water tank 10 and input it into the nozzle 17 through the water supply hose 14, the diversion pipe 15 and the dispersion disc 16. Then, the nozzle 17 sprays the heating sleeve 9 inside the upper hot mold 6 and the lower hot mold 8. Then, the electric push rod 18 extends and retracts the push block 19 and the two push blocks 19, so that the push block 19 drives multiple dispersion discs 16 to spray the inner surface of the upper and lower heating sleeves 9, so that the release agent can be evenly sprayed onto the inner surface of the heating sleeve 9.

[0030] Reference Figure 6As shown, the chassis 7 has multiple toothed grooves 20 on its outer side, and a fixed plate 21 is fixedly connected to the top of the chassis 7. A servo motor 22 is fixedly connected to the inner side of the operating table 1, and a gear 23 is fixedly connected to the output end of the servo motor 22. One side of the gear 23 meshes with the inner side of the toothed groove 20. The servo motor 22 drives the gear 23 to transmit power to the toothed groove 20 on the outer side of the chassis 7, so that the chassis 7 and the fixed plate 21 can transmit power to multiple lower hot molds 8 and air pipes 27, so that multiple lower hot molds 8 can reciprocate to perform vulcanization processing of basketball bladder.

[0031] Reference Figure 5 and Figure 3 As shown, the sealing inflation mechanism includes an inflator 24. The bottom of the inflator 24 is fixedly connected to the inner side of the operating table 1. A positioning frame 25 is fixedly connected to the output end of the inflator 24. An air supply channel 26 is opened inside the positioning frame 25. An air supply pipe 27 is inserted into the inner side of the air supply channel 26. Two sealing rings 28 are fixedly connected to the outer side of the air supply pipe 27. The outer side of the sealing rings 28 is engaged with the inner side of the air supply channel 26. The inner side of the air supply pipe 27 is fixedly connected to the inner side of the fixing plate 21. An air supply plate 29 is fixedly connected to the top of the air supply pipe 27. Multiple connecting pipes 30 are connected to the outside of the air supply plate 29. An electric control valve 31 is installed on the outside of the connecting pipe 30. Two sealing rings 28 seal the inside of the air supply pipe 27 and the air supply channel 26, so that the air supply pipe 27 maintains sufficient sealing during rotation. Then, the air inflator 24 inflates the inside of the air supply plate 29 through the air supply channel 26 and the air supply pipe 27. Then, the air inside the air supply plate 29 can enter the basketball bladder that needs to be vulcanized through the corresponding connecting pipe 30 by opening and closing the electric control valve 31.

[0032] The working principle of this utility model is as follows: During the vulcanization process of the basketball bladder, the hydraulic rod 3 first moves the pressure plate 4 and the two upper heating molds 6 towards the top of the multiple lower heating molds 8, bringing the two upper heating molds 6 and the lower heating molds 8 closer together. The release agent is then introduced into the water tank 10 through the inlet pipe 11. Then, two water pumps 12 draw the release agent from the water tank 10 through the suction pipe 13, and then inject the release agent into the corresponding two dispersion discs 16 through the water delivery hose 14 and the diversion pipe 15. Under pressure, the release agent inside the dispersion discs 16 is sprayed onto the surface of the heating jacket 9 inside the upper heating molds 6 and lower heating molds 8 through three nozzles 17. Simultaneously, the electric push rod 18 pushes the push block 19, causing the two dispersion discs 16 to move between the upper heating molds 6 and lower heating molds 8, thus... The release agent can be sprayed relatively comprehensively onto the inner surface of the heating jacket 9 inside the upper hot mold 6 and the lower hot mold 8. Then, the staff connects one end of the basketball bladder to the connecting pipe 30 and places the basketball bladder into the upper hot mold 6. Then, the hydraulic rod 3 and the pressure plate 4 drive the two lower hot molds 8 to overlap with the upper hot mold 6 containing the basketball bladder. The air inflator 24 inflates the inside of the air supply plate 29 through the air supply channel 26 and the air supply pipe 27. Then, the electric control valve 31 on the outside of the connecting pipe 30 connected to the basketball bladder is opened, so that the gas inside the air supply plate 29 enters the inside of the basketball bladder through the corresponding connecting pipe 30, so that the basketball bladder is inflated inside the upper hot mold 6 and the lower hot mold 8. Then, under the heating of the upper hot mold 6, the lower hot mold 8 and the heating jacket 9, the basketball bladder completes the vulcanization reaction.

[0033] After the two basketball bladders are vulcanized, the servo motor 22 drives the gear 23 to transmit power to the toothed groove 20 on the outside of the chassis 7, causing the chassis 7 to deflect multiple lower heating molds 8, so that the two upper heating molds 6 without basketball bladders are moved to the bottom of the two spraying mechanisms. Then, the pressure plate 4 moves up and down repeatedly, so that the corresponding upper heating mold 6 and the other two lower heating molds 8 are brought closer together. Then, the release agent is sprayed onto the upper heating mold 6, lower heating mold 8 and the inside of the heating sleeve 9 again. Then, the two basketball bladders are repeatedly inflated and vulcanized. Finally, after the basketball bladders are placed on the top of multiple upper heating molds 6, the two basketball bladders that have cooled down are removed, and the chassis 7 is rotated in the opposite direction to quickly vulcanize the basketball bladders.
