[0002] A sealing ring is a common rubber product widely used in various mechanical equipment to prevent liquid or gas leakage. In the current processing of rubber sealing rings, a flat vulcanizing machine is usually used. Workers place the cut rubber strips between the fixed mold and the moving mold, and then use jacks to close the fixed mold and the moving mold, so that the rubber product is subjected to a certain pressure and temperature, thereby vulcanizing it into a finished product.

[0003] In the prior art, the rubber feeding device for processing sealing rings with authorization announcement number CN217021170U includes a mold group installed on a flip-type flat vulcanizing machine.

Each mold groove includes a first groove for preparing coarse-sized sealing rings. The inner and outer sides of the first groove are provided with second grooves for preparing fine-sized sealing rings.

[0004] When using this device, workers need to manually place the cut rubber strips one by one onto the mold surface. Each processing requires workers to spend a lot of time placing the rubber strips, which affects the production efficiency of the sealing rings. Furthermore, if the rubber strips are not laid evenly when placed manually, it can easily cause the thickness of the sealing rings to be uneven after molding, affecting the quality of the product.

[0024] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a rubber feeding device for processing sealing rings, including a vulcanizing machine 1, an installation platform 4 inside the vulcanizing machine 1, a moving plate 6 on the top of the installation platform 4, a lower mold 7 fixedly connected to the top of the moving plate 6, electric push rods 11 fixedly connected to both sides of the top of the installation platform 4, an installation plate 12 fixedly connected to the output end of the electric push rod 11, a second fixing plate 24 at the bottom of the installation plate 12, and multiple push plates 25 fixedly connected to the bottom of the second fixing plate 24 in a linear array, with inclined plates 27 at the bottom of the multiple push plates 25.

The positioning wheel 20 and the surface of the limiting block 22 are in rolling contact. When working, the inner tooth block 16 rotates along the outer surface of the limiting block 22, thereby driving the rubber strips on the top of the inclined plate 27 to move in a stepping motion, and placing the rubber strips evenly on the top of the lower mold 7 one by one.

[0027] The bottom of the internal tooth block 16 is fixedly connected to a second slide rod 23. The second slide rod 23 passes through the limiting box 13 and is slidably connected to the limiting box 13. The bottom of the second slide rod 23 is fixedly connected to the second fixing plate 24.

[0028] Both sides of the bottom of the mounting plate 12 are fixedly connected to the third fixing plate 26. The inclined plate 27 is fixedly connected between the two third fixing plates 26. A push rod 28 is provided on the rear side of the inclined plate 27. The two ends of the push rod 28 pass through the two third fixing plates 26 respectively and are slidably connected to the two third fixing plates 26. Both ends of the push rod 28 are fixedly connected to the L-shaped rod 29. Both ends of the push plate 25 at the front of the device are fixedly connected to the transmission rod 30. One end of each of the two L-shaped rods 29 is provided with a limit groove. One end of each of the two transmission rods 30 is slidably connected to the inside of the two slide grooves. Both of the two third fixing plates 26 are provided with through holes that conform to the movement trajectory of the transmission rod 30. During operation, the push rod 28 slides back and forth to push the rubber strips stacked inside the positioning rod 31 to the rear side of the push plate 25 for feeding.

[0029] Two positioning rods 31 are fixedly connected to one side of the third fixing plate 26. A pressure rod 32 is set between the two third fixing plates 26. Two rotating wheels are fixedly connected to both ends of the two pressure rods 32. The four rotating wheels are in rolling contact with the four positioning rods 31 respectively. After the worker replenishes the rubber strips, the pressure rods 32 can press the rubber strips down, so that the rubber strips are stacked neatly.

[0030] The vulcanizing machine 1 is equipped with a hydraulic cylinder 2. The output end of the hydraulic cylinder 2 is fixedly connected to the mounting platform 4. Support rods 3 are fixedly connected to the four corners inside the vulcanizing machine 1. The four support rods 3 pass through both sides of the mounting platform 4 and are slidably connected to the mounting platform 4. A hydraulic rod 5 is fixedly installed on the rear side of the mounting platform 4. The output end of the hydraulic rod 5 is fixedly connected to the moving plate 6. The moving plate 6 is slidably connected to the inner top of the mounting platform 4.

[0031] The lower mold 7 is hinged to the upper mold 8 on one side. The upper mold 8 is fixedly connected to the side away from the lower mold 7 with a limit rod 9. Limit rod 9 is rotatably connected to both sides with limit wheels. The top of the mounting platform 4 is fixedly connected to both sides with vertical plates 10. The two vertical plates 10 are respectively fixedly connected to guide rails that are adapted to the two limit wheels on opposite sides.

[0032] It should be noted that this utility model is a rubber feeding device for processing sealing rings. The working method of the vulcanizing machine 1 is a mature existing technology, so it will not be described in detail here. During operation, the hydraulic rod 5 raises the moving plate 6 to pull the lower mold 7 into the vulcanizing machine 1. While the lower mold 7 moves, the upper mold 8 moves with it. At this time, the limiting wheels on both sides of the limiting rod 9 move along the guide rail, causing the upper mold 8 to gradually approach the lower mold 7, so that the mold closes. After the mold at the top of the moving plate 6 enters the vulcanizing machine 1, the hydraulic cylinder 2 works to drive the installation platform 4 to rise as a whole, so that the hot pressing device set at the top of the vulcanizing machine 1 processes the rubber strip inside the mold.

[0033] During operation, workers can pre-place rubber strips between the two positioning rods 31 and on top of the inclined plate 27, stacking multiple rubber strips on top of the inclined plate 27. Then, the hydraulic rod 5 pulls the moving plate 6 into the vulcanizing machine 1. The top of the internal gear block 16 is rotatably connected to the positioning wheel 20 via the first sliding rod 19. The limiting block 22 works in conjunction with the positioning wheel 20. During operation, the limiting block 22 moves along its outer surface. The positioning wheel 20 limits the movement of the internal gear block 16, ensuring that the internal gear block 16 is always meshed with the gear 18 during movement. As the hydraulic rod 5 pulls the moving plate 6, the motor 17 drives the gear 18 to rotate. The rotation of the gear 18 causes the internal gear block 16 and its bottom pusher plate 25 to rotate along the surface of the limiting block 22. During operation, the inner tooth block 16 first drives the pusher plate 25 to move backward. At this time, the pusher plate 25 and the inclined plate 27 are in contact, pushing the rubber strip along the inclined plate 27 to the surface of the lower mold 7. Then, the inner tooth block 16 moves upward and then rotates forward, so that the pusher plate 25 returns to the initial position to push the next rubber strip. While the motion groove 15 rotates, it drives the pusher rod 28 to reciprocate through the transmission rod 30, thereby pushing the rubber strips between the positioning rods 31 one by one to the rear side of the motion groove 15. This allows the motion groove 15 to continuously place and push the rubber strips. The worker can replenish the rubber strips inside the positioning rods 31 while the vulcanizing machine 1 is processing the rubber strips, thereby shortening the interval time of continuous processing of sealing rings by the vulcanizing machine 1 and improving production efficiency.

[0034] After processing, hydraulic cylinder 2 drives the mounting platform 4 to descend, and then hydraulic rod 5 pushes the moving plate 6 out of the vulcanizing machine 1. When the moving plate 6 enters the vulcanizing machine 1, electric push rod 11 drives the mounting plate 12 to rise away from the surface of the moving plate 6. After processing, when the moving plate 6 moves forward, the guide rail drives the upper mold 8 to rotate around the hinge between the upper mold 8 and the lower mold 7 to open the mold. At this time, the worker can take out the processed sealing ring. Then, electric push rod 11 can drive the mounting plate 12 to descend so that the bottom of the inclined plate 27 is close to the surface of the lower mold 7, and then the next round of processing is carried out.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
