Description

Technical Field

[0001] This invention relates to the field of ball production technology, and in particular to an automated vulcanization device for ball liner and its usage method. Background Technology

[0002] The manufacturing process of the ball bladder mainly includes rubber refining, leather making, perforation, ball head gluing, ball bladder forming, vulcanization, and inspection. Vulcanization involves placing the ball bladder in a vulcanization mold, inflating it, and heating it to allow the sulfur in the rubber to react chemically with the rubber, resulting in vulcanized rubber that is non-sticky and not easily broken.

[0003] Existing vulcanization equipment, for example:

[0004] CN201620965492.2 discloses an intelligent basketball rubber bladder vulcanization equipment, which includes a frame and a vulcanization mold mounted on the frame via a clamp. The vulcanization mold includes a hemispherical fixed mold mounted on the worktable of the frame and a hemispherical movable mold mounted above the fixed mold and movable up and down along the fixed mold. The fixed mold has a positioning groove on the front side of its upper edge for positioning the air hole pin of the basketball bladder, and a positioning protrusion on the rear side of its upper edge opposite to the positioning groove for positioning the rubber parts hole of the basketball bladder. This utility model, by providing a positioning groove for positioning the air hole pin of the basketball bladder and a positioning protrusion for positioning the rear rubber parts of the intelligent basketball bladder on the upper edge of the vulcanization fixed mold, can effectively fix the position of the bladder during the vulcanization process, improve the consistency of the shape of the bladder after vulcanization, effectively avoid the generation of defective bladders during the vulcanization process, and is conducive to efficient production by enterprises.

[0005] CN202221776298.1 discloses a vulcanizing equipment for basketball rubber bladders, comprising a frame workbench, a fixed mold, a hydraulic cylinder, a crossbeam, and a moving mold. Heating grooves are formed on the outer walls of opposite sides of both the moving and fixed molds, and a vulcanizing bladder is disposed on the inner wall of the heating groove. The vulcanizing bladder has a circular cross-section, and several equally spaced heating plates are arranged on the arc-shaped outer wall of the vulcanizing bladder. Several equally spaced heat-conducting protrusions are arranged on the arc-shaped outer wall of the vulcanizing bladder near the heating plates, with the heat-conducting protrusions alternating with the heating plates. Reflective foil is disposed on the bottom inner wall of the heating groove. This invention can achieve a good heating effect, improve the vulcanization effect of the basketball bladder, and enhance the production quality of the basketball bladder.

[0006] It is known that existing vulcanizing equipment requires manual operation of the following steps: pasting leather and inner liner (laying leather into the vulcanizing mold - placing the ball-shaped inner liner into the vulcanizing mold - closing the mold - opening the mold after the set vulcanization time) - pasting labels - vulcanization produces granular protrusions on the outer leather (placing the inner liner into the vulcanizing mold - opening the mold and removing it after the set vulcanization time). In other words, existing vulcanizing equipment has the problems of relatively simple structure, low degree of automation, and high labor costs. Summary of the Invention

[0039] The first and second infrared sensors are both electrically connected to the electric switching valve between the suction cup and the vacuum pump of the first transfer mechanism and the lifting cylinder of the first transfer mechanism via the controller. The third infrared sensor is electrically connected to the opening and closing cover drive motor of the leather lining vulcanization mechanism via the controller. The fourth infrared sensor is electrically connected to the opening and closing cover drive motor of the outer leather vulcanization mechanism via the controller. The fifth and sixth infrared sensors are both electrically connected to the electric switching valve between the suction cup and the vacuum pump of the third transfer mechanism and the lifting cylinder of the third transfer mechanism. The controller is also electrically connected to the dual-head motor.

[0040] A method of using an automated vulcanizing device for ball liner includes the following steps:

[0041] S1. Cutting:

[0042] Place the block of leather on the lower die of the shearing and pushing mechanism, open the shearing and pushing mechanism, press down the upper die, and use the impact force of the upper die to cut the block of leather into multiple blocks of leather. Close the shearing and pushing mechanism, open the pushing cylinder to push out the lower die, and the workers take out the cut waste material during the pushing process.

[0043] S2. The first transfer mechanism transfers multiple pieces of leather to the leather lining vulcanization mechanism:

[0044] The first infrared sensor detects that the lower mold is directly below the first transfer mechanism. The controller opens the suction cup and the electric switch valve of the first transfer mechanism. The lifting cylinder of the first transfer mechanism moves the suction cup downward, using negative pressure to simultaneously suck up multiple pieces of leather. At this time, the controller opens the dual-head motor after a set delay. The dual-head motor drives the left and right adjusting screws to rotate through the first and second bevel gears. With the screw engagement, the first transfer mechanism moves towards the leather lining vulcanization mechanism until the second infrared sensor detects that the first transfer mechanism is directly above the leather lining vulcanization mechanism. The controller then closes the electric switch valve of the first transfer mechanism. Under the action of their own gravity, the multiple pieces of leather fall into and are laid flat inside the semi-circular moving mold and semi-circular fixed mold of the leather lining vulcanization mechanism.

[0045] S3, Vulcanized Leather Lining:

[0046] After a set delay time, the controller turns on the dispensing motor. The dispensing motor drives the dispensing baffle to rotate via the dispensing shaft. The ball liner at the front end loses the obstruction of the baffle and rolls down along the feeding channel into the leather liner vulcanization mechanism. After the third infrared sensor detects the ball liner falling, the controller opens the opening and closing cover drive motor, which drives the semi-circular moving mold of the leather liner vulcanization mechanism to rotate towards the semi-circular fixed mold until it closes and vulcanization begins. After a set time, the opening and closing cover drive motor rotates in the opposite direction, opening the semi-circular moving mold to obtain the blank.

[0047] S4. The second transfer mechanism transfers the billet to the outer skin vulcanization mechanism:

[0048] The lifting cylinder of the second transfer mechanism extends and uses negative pressure to suck up the blank. Under the cyclic operation of the synchronous drive mechanism, the blank moves towards the outer vulcanization mechanism. During the movement, the bottom end of the blank contacts the adhesive surface of the label film on the label roller. The label film is pasted on the bottom end of the blank, and the bottom film of the label film is wrapped around the tear film roller. The blank with the label film pasted on it continues to be conveyed and touches the cutting plate of the cutting blade assembly, causing it to rotate. This causes the cutting plate to rotate towards the label film, breaking the label film. This continues until the fourth infrared sensor detects that the second transfer mechanism is in place. The electric switch valve of the second transfer mechanism closes, and the blank falls into the semi-circular fixed mold of the outer vulcanization mechanism.

[0049] S5. Curd outer skin vulcanization:

[0050] The fifth infrared sensor detects that the billet falls into the semi-circular fixed mold of the outer skin vulcanization mechanism. The controller opens the opening and closing cover drive motor of the semi-circular fixed mold outer skin vulcanization mechanism, which drives the semi-circular moving mold of the outer skin vulcanization mechanism to rotate towards the semi-circular fixed mold until it closes and vulcanization begins. After a set time, the opening and closing cover drive motor rotates in the opposite direction, opens the semi-circular moving mold, and the finished product is obtained.

[0051] S6. The third transfer mechanism transfers the finished product to the collection box:

[0052] The telescopic rod of the third transfer mechanism extends and uses a suction cup to pick up the finished product. Under the cyclical operation of the synchronous drive mechanism, the finished product moves towards the collection box until the sixth infrared sensor detects the position signal. At this point, the electric switch valve of the third transfer mechanism closes, and the finished product falls into the collection box under its own gravity.

[0053] The present invention has the following beneficial effects:

[0054] The automated vulcanization device for ball liner and its operation method allow for automatic vulcanization of the ball liner with only one worker required for supervision, improving work efficiency and reducing labor costs and intensity.

[0090] A method of using an automated vulcanizing device for ball liner includes the following steps:

[0091] S1. Cutting:

[0092] Place the block of leather on the lower die 22 of the shearing and pushing mechanism 2, open the shearing and pushing mechanism 2, press down the upper die 21, and use the impact force of the upper die 21 to cut the block of leather into multiple blocks of leather. Close the shearing and pushing mechanism 2, open the pushing cylinder 23 to push out the lower die 22, and the staff removes the cut waste material during the pushing process.

[0093] S2, The first transfer mechanism 3 transfers multiple pieces of leather to the leather lining vulcanization mechanism 4:

[0094] The first infrared sensor detects that the lower mold 22 is directly below the first transfer mechanism 3. The controller opens the electric switch valve of the suction cup and the first transfer mechanism 3. The lifting cylinder 31 of the first transfer mechanism drives the suction cup to move down, using negative pressure to simultaneously suck up multiple pieces of leather. At this time, the controller opens the dual-head motor 14 after a set delay. The dual-head motor 14 drives the left adjusting screw 11 and the right adjusting screw 15 to rotate through the first bevel gear 12 and the second bevel gear 13. Under the threaded engagement, the first transfer mechanism 3 moves towards the leather lining vulcanization mechanism 4 until the second infrared sensor detects that the first transfer mechanism 3 is directly above the leather lining vulcanization mechanism 4. The controller closes the electric switch valve of the first transfer mechanism 3. Under the action of their own gravity, the multiple pieces of leather fall into and are laid flat inside the semi-circular moving mold 41 and the semi-circular fixed mold of the leather lining vulcanization mechanism.

[0095] S3, Vulcanized Leather Lining:

[0096] After a set delay time, the controller turns on the dispensing motor. The dispensing motor drives the dispensing baffle to rotate via the dispensing shaft. The ball liner at the front end loses the obstruction of the baffle and rolls down along the feeding channel into the leather liner vulcanization mechanism 4. After the third infrared sensor detects the ball liner falling, the controller opens the opening and closing cover drive motor, which drives the semi-circular moving mold 41 of the leather liner vulcanization mechanism to rotate towards the semi-circular fixed mold until it closes and vulcanization begins. After a set time, the opening and closing cover drive motor rotates in the opposite direction, opening the semi-circular moving mold to obtain the blank.

[0097] S4, the second transfer mechanism 8 transfers the billet to the outer skin vulcanization mechanism 6:

[0098] The lifting cylinder of the second transfer mechanism 8 extends and uses negative pressure to suck up the blank. Under the cyclic operation of the synchronous drive mechanism 1, the blank moves towards the outer skin vulcanization mechanism 6. During the movement, the bottom end of the blank contacts the adhesive surface of the label film on the label roller. The label film is pasted on the bottom end of the blank. The bottom film of the label film is wrapped around the tear film roller 51. The blank with the label film pasted on it continues to be conveyed and touches the cutting plate 54 of the cutting blade assembly, causing it to rotate. This causes the cutting plate 54 to rotate towards the label film, breaking the label film. This continues until the fourth infrared sensor detects that the second transfer mechanism 8 is in place. The electric switch valve of the second transfer mechanism 8 is closed, and the blank falls into the semi-circular fixed mold 62 of the outer skin vulcanization mechanism.

[0099] S5. Curd outer skin vulcanization:

[0100] The fifth infrared sensor detects that the billet falls into the semi-circular fixed mold 62 of the outer skin vulcanization mechanism. The controller opens the opening and closing cover drive motor of the semi-circular fixed mold outer skin vulcanization mechanism 6, which drives the semi-circular moving mold 61 of the outer skin vulcanization mechanism to rotate towards the semi-circular fixed mold until it closes and vulcanization begins. After a set time, the opening and closing cover drive motor rotates in the opposite direction, opens the semi-circular moving mold, and the finished product is obtained.

7. A method of using an automated vulcanizing device for ball liner as described in any one of claims 1-6, characterized in that: Includes the following steps: S1. Cutting: Place the block of leather on the lower die of the shearing and pushing mechanism, open the shearing and pushing mechanism, press down the upper die, and use the impact force of the upper die to cut the block of leather into multiple blocks of leather. Close the shearing and pushing mechanism, open the pushing cylinder to push out the lower die, and the workers take out the cut waste material during the pushing process. S2. The first transfer mechanism transfers multiple pieces of leather to the leather lining vulcanization mechanism: The first infrared sensor detects that the lower mold is directly below the first transfer mechanism. The controller opens the suction cup and the electric switch valve of the first transfer mechanism. The lifting cylinder of the first transfer mechanism moves the suction cup downward, using negative pressure to simultaneously suck up multiple pieces of leather. At this time, the controller opens the dual-head motor after a set delay. The dual-head motor drives the left and right adjusting screws to rotate through the first and second bevel gears. With the screw engagement, the first transfer mechanism moves towards the leather lining vulcanization mechanism until the second infrared sensor detects that the first transfer mechanism is directly above the leather lining vulcanization mechanism. The controller then closes the electric switch valve of the first transfer mechanism. Under the action of their own gravity, the multiple pieces of leather fall into and are laid flat inside the semi-circular moving mold and semi-circular fixed mold of the leather lining vulcanization mechanism. S3, Vulcanized Leather Lining: After a set delay time, the controller turns on the dispensing motor. The dispensing motor drives the dispensing baffle to rotate via the dispensing shaft. The ball liner at the front end loses the obstruction of the baffle and rolls down along the feeding channel into the leather liner vulcanization mechanism. After the third infrared sensor detects the ball liner falling, the controller opens the opening and closing cover drive motor, which drives the semi-circular moving mold of the leather liner vulcanization mechanism to rotate towards the semi-circular fixed mold until it closes and vulcanization begins. After a set time, the opening and closing cover drive motor rotates in the opposite direction, opening the semi-circular moving mold to obtain the blank. S4. The second transfer mechanism transfers the billet to the outer skin vulcanization mechanism: The lifting cylinder of the second transfer mechanism extends and uses negative pressure to suck up the blank. Under the cyclic operation of the synchronous drive mechanism, the blank moves towards the outer vulcanization mechanism. During the movement, the bottom end of the blank contacts the adhesive surface of the label film on the label roller. The label film is pasted on the bottom end of the blank, and the bottom film of the label film is wrapped around the tear film roller. The blank with the label film pasted on it continues to be conveyed and touches the cutting plate of the cutting blade assembly, causing it to rotate. This causes the cutting plate to rotate towards the label film, breaking the label film. This continues until the fourth infrared sensor detects that the second transfer mechanism is in place. The electric switch valve of the second transfer mechanism closes, and the blank falls into the semi-circular fixed mold of the outer vulcanization mechanism. S5. Curd outer skin vulcanization: The fifth infrared sensor detects that the billet falls into the semi-circular fixed mold of the outer skin vulcanization mechanism. The controller opens the opening and closing cover drive motor of the semi-circular fixed mold outer skin vulcanization mechanism, which drives the semi-circular moving mold of the outer skin vulcanization mechanism to rotate towards the semi-circular fixed mold until it closes and vulcanization begins. After a set time, the opening and closing cover drive motor rotates in the opposite direction, opens the semi-circular moving mold, and the finished product is obtained. S6. The third transfer mechanism transfers the finished product to the collection box: The telescopic rod of the third transfer mechanism extends and uses a suction cup to pick up the finished product. Under the cyclical operation of the synchronous drive mechanism, the finished product moves towards the collection box until the sixth infrared sensor detects the position signal. At this point, the electric switch valve of the third transfer mechanism closes, and the finished product falls into the collection box under its own gravity.
