Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machines, and more particularly to a vulcanizing machine for producing rubber diaphragms. Background Art

[0002] A vulcanizer is a machine that vulcanizes various rubber and plastic products. It features functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time-out alarms. Vulcanizers are available in three types: electric, steam, and thermal oil. They are also known as flat plate vulcanizers, foam plate vulcanizers, and rubber vulcanizers.

[0003] After the existing rubber vulcanizer completes the production of the rubber diaphragm, the rubber diaphragm needs to be removed from the mold. Since the rubber diaphragm will adhere to the inner cavity wall of the lower mold, in actual operation, the worker clamps it with one hand and uses a high-pressure air gun with the other hand to separate the rubber diaphragm and the mold. However, this type of operation is affected by manual experience, is difficult to control efficiency, and is also very dangerous. A solution is proposed below to address the above problems. Utility Model Content

[0015] Second, the movement of the extension rod can be controlled by the double-headed cylinder, so that the starting finger and the clamping claw can be controlled to move between the rubber diaphragm and the lower mold. The rotation of the rotating cylinder can drive the rotation of the rotating frame, thereby driving the extension rod and the pneumatic finger to move out of the vulcanizer body.

[0016] 3. The stabilizing component is used to limit the mounting frame, ensuring the stability of the up and down movement of the mounting frame and reducing shaking.

[0020] 7. The controller is used for the interaction between various actions and to control the startup time and sequence between various components. BRIEF DESCRIPTION OF THE DRAWINGS

The inner rod 18 and the outer cylinder 19 are interlaced and matched. The inner rod 18 and the outer cylinder 19 are slidably matched. The inner side surface of the outer cylinder 19 is symmetrically provided with a limiting groove. A limiting block is slidingly set inside the limiting groove. The limiting block is fixedly connected to the inner rod 18. The design of the limiting groove and the limiting block can effectively prevent the inner rod and the outer cylinder from separating during the mutual movement. The up and down movement can be achieved by lifting the cylinder 5. At the same time, the stabilizing assembly 17 can improve the stability.

[0031] A moving assembly 6 is provided on the output end of the lifting cylinder 5. The moving assembly 6 includes a rotating motor 12, a mounting frame 13, a double-headed cylinder 14 and an extension rod 15. The mounting frame 13 is installed at the output end of the lifting cylinder 5. The top of the inner rod 18 is fixedly connected to the bottom of the mounting frame 13. The rotating motor 12 is installed on the top of the mounting frame 13. The rotating motor 12 is electrically connected to the controller 23. At the same time, the rotating motor 12 is a stepping motor. The stepping motor can accurately control the rotation angle to ensure accuracy. A rotating frame 16 is installed on the top of the rotating motor 12. An annular guide groove 20 is provided on the mounting frame 13. The guide groove 20 is concentric with the rotating shaft of the rotating motor 12. A number of guide blocks 21 are provided inside the guide groove 20 for uniform rotation. The guide blocks 21 are fixedly connected to the rotating frame 16. The design of the guide groove 20 and the guide blocks 21 can limit the rotating frame 16. The guide block 21 and the guide groove 20 are adapted to each other, and the inverted T-shaped design can effectively avoid the separation between the guide block 21 and the guide groove 20. The double-headed cylinder 14 is installed on the top of the rotating frame 16, and the double-headed cylinder 14 is electrically connected to the controller 23. There are two extension rods 15, and the two extension rods 15 are fixedly connected to the output ends of the double-headed cylinder 14 respectively. The two extension rods 15 can be controlled to move in opposite directions at the same time by the double-headed cylinder 14. A guide rod 22 is installed on the rotating frame 16, and the guide rod 22 passes through the two extension rods 15, and the guide rod 22 and the extension rod 15 slide together. The guide rod 22 guides and limits the movement of the two extension rods 15 to ensure the stability of the extension rod 15.

[0032] The movement of the extension rod 15 can be controlled by the double-headed cylinder 14, thereby controlling the starting finger and the clamping claw 8 to move between the rubber diaphragm and the lower mold 3. The rotation of the rotating cylinder can drive the rotating frame 16 to move, thereby driving the extension rod 15 and the pneumatic finger 7 to move out of the vulcanizer body 1.

[0033] The extension rod 15 is symmetrically connected to one end of the lower mold 3 with a pneumatic finger 7 (the pneumatic finger 7 is also known as a pneumatic gripper or a pneumatic gripper, which is an actuator that uses compressed air as power to clamp or grab workpieces). The pneumatic finger 7 is electrically connected to the controller 23. The two moving ends of the pneumatic finger 7 are respectively provided with grippers 8. The grippers 8 are in the shape of a right-angled trapezoid, and the smaller upper end faces of the right-angled trapezoids of the two grippers 8 on the same pneumatic finger 7 correspond to each other. The right-angled trapezoid design can facilitate the insertion of the grippers 8 between the rubber diaphragm and the lower mold 3 through the hypotenuse. An air duct 9 is provided on the gripper 8 at the bottom end of the same pneumatic finger 7. The air duct 9 passes through the gripper 8. One end of the air duct 9 is connected to an air pipe 10. The air pipe 10 is connected to an electric control valve 11 that controls the air pipe 10. The electric control valve 11 is electrically connected to the controller 23.

[0034] The two clamping jaws 8 are pushed to move by the pneumatic fingers 7 to realize the clamping and loosening actions, so that the rubber diaphragm is clamped by the two clamping jaws 8. The electric control valve 11 connects the air pipe 10 and the external high-pressure gas equipment, so that the high-pressure gas enters between the rubber diaphragm and the lower mold 3 through the air pipe 10 and the air channel 9. The rubber diaphragm and the lower mold 3 are separated by the high-pressure gas to complete the unloading. The whole process is automated, no manual operation is required, high safety, stable efficiency, and will not hinder the normal operation of the vulcanizer body 1.

[0035] Working principle:

[0036] During use, the rubber diaphragm is produced through the cooperation between the vulcanizer body 1, the upper mold 2 and the lower mold 3. When the vulcanizer body 1 completes the production of the rubber diaphragm, it will drive the upper mold 2 to separate from the lower mold 3. At the same time, the vulcanizer body 1 will send an electrical signal to the controller 23. The controller will first start the lifting cylinder 5 after receiving the signal. The lifting cylinder 5 will drive the moving component 6 and the pneumatic finger 7 to move upward between the upper mold 2 and the lower mold 3. The control will send a signal to the rotating motor 12. The rotating motor 12 will drive the rotating frame 16 to rotate. The rotating frame 16 will drive the double-headed cylinder 14 and the extension rod 15 to rotate, thereby The pneumatic clamping jaws 8 are driven to move through the gap between the upper die 2 and the lower die 3 to the top of the lower die 3, the lifting cylinder 5 is reset, and the pneumatic fingers 7 are driven to reset until the clamping jaws 8 at the bottom are moved to the same height as the top of the lower die 3. The controller 23 controls the double-headed cylinder 14 to start, and the double-headed cylinder 14 drives the extension rod 15 to move closer to each other, so that the extension rod 15 drives the pneumatic fingers 7 and the clamping jaws 8 to move, and the clamping jaws 8 are inserted between the rubber diaphragm and the lower die 3. The inclined surface of the clamping jaws 8 facilitates insertion, and the inclined surface can push the waste edge of the rubber diaphragm upward until it moves between the two clamping jaws 8. The controller 23 controls the start The pneumatic finger is started, and the pneumatic finger 7 drives the two clamps 8 to move. The two clamps 8 clamp the waste edge of the rubber diaphragm. The controller 23 controls the electric control valve 11 to open, and the external high-pressure gas enters the gap between the rubber diaphragm and the lower mold 3 through the air pipe 10 and the air channel 9, thereby separating the rubber diaphragm and the lower mold 3 through the high-pressure gas. The controller 23 controls the lifting cylinder 5 to start, and the lifting cylinder 5 drives the moving parts to rise, driving the pneumatic finger 7 and the clamps 8 to move, thereby driving the rubber diaphragm and the lower mold 3 to separate, so that the rubber diaphragm is between the upper mold 2 and the lower mold 3. The controller 2 3 controls the rotary motor 12 to reset, and the rotary motor 12 drives the extension rod 15 and the pneumatic finger 7 to rotate, thereby driving the clamping claw 8 to rotate, that is, driving the rubber diaphragm to move out from between the upper mold 2 and the lower mold 3 and out of the interior of the vulcanizer body 1, so that the vulcanizer can continue to operate. The pneumatic finger 7 is controlled to reset, and the rubber diaphragm falls under the action of its own gravity, completing the material return. At the same time, the controller 23 controls the lifting cylinder 5 and the double-headed cylinder 14 to reset, waiting for the next operation. The fully automated operation does not require manual operation, has high safety, stable efficiency, and will not hinder the normal operation of the vulcanizer body 1.
