Description

Technical Field

[0001] The utility model relates to the technical field of rubber band production, and more specifically, to a vulcanizing device for rubber band production. Background Art

[0002] During the production process of rubber bands, chemicals such as sulfur need to be incorporated into the rubber band raw materials to make them more elastic. The main steps are to first sprinkle the chemicals on the rubber sheets bundled into rolls, and then use a roller to roll them evenly with the chemicals, thus completing the chemical mixing operation.

[0003] When chemicals such as sulfur are sprinkled on the surface of the rubber band raw material, the sulfur is simply sprinkled on the outside of the rubber roll, and the inside of the rubber roll is not easily exposed to chemicals such as sulfur. Even after being rolled by a roller, it will only expand the outer area of ​​the rubber roll, allowing the chemicals to fully contact the outside of the rubber roll, thereby increasing the overall chemical mixing rate of the rubber roll, but it is not easy to change the amount of chemicals mixed inside the rubber roll. Therefore, there is always a difference in the mixing amount of chemicals such as sulfur inside and outside the rubber roll, which leads to insufficient vulcanization of the rubber raw material and reduces the quality of the rubber band.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] Vulcanizing equipment for rubber band production, such as Figure 1-Figure 3 As shown, it includes a vulcanization box 1, on the inner side wall of the vulcanization box 1 are fixedly connected two symmetrical steam engines 2, a mixing box 3 is arranged at the water inlet of the steam engine 2, a cutting device for cutting rubber band raw materials is arranged between the two steam engines 2, a connecting plate 4 is rotatably connected to the top of the vulcanization box 1, and a pushing device for moving the rubber band raw materials close to the cutting device is arranged in the vulcanization box 1. Through the connecting plate 4, the top of the vulcanization box 1 can be opened, and the required amount of sulfur raw materials can be added to the mixing box 3 and mixed with water to form a vulcanizing agent, so that the vulcanizing agent can come to the surface of the rubber band raw materials along the steam in the steam engine 2, and the rubber band raw materials can be cut into small pieces by the cutting device, so that the rubber band raw materials and the vulcanizing agent can be more fully contacted, so that the rubber band raw materials can be fully vulcanized, and the obtained rubber bands can have higher wear resistance and aging resistance. The rubber band raw materials can pass through the cutting device for multiple times through the pushing device, so that the rubber band raw materials can be cut smaller and more evenly.

[0023] The cutting device includes a plurality of rotating rods 5, a gear 1 6, two gear 2s 7 and a plurality of blades 8. The gear 1 6 is fixedly connected to the central rotating rod 5. The two gear 2s 7 are meshed on both sides of the gear 1 6. The gear 2 7 is fixedly connected to the rotating rods 5 on both sides. A motor 1 9 is fixedly connected to the outside of the vulcanization box 1. The output end of the motor 1 9 is fixedly connected to the gear 1 6. A plurality of blades 8 are fixedly connected to the rotating rod 5. The plurality of rotating rods 5 are arranged in parallel in the vulcanization box 1. When cutting, the motor 1 9 is started to drive the gear 1 6 to rotate. Since the gear 1 6 and the gear 2 7 are meshed with each other, the gear 2 7 can be driven to rotate, thereby driving the rotating rod 5 and the blade 8 to rotate, and the rubber band raw material is cut.

[0024] The pushing device includes an extrusion plate 10 and a cylinder 11. The cylinder 11 is fixedly connected to the bottom of the vulcanization box 1. The piston of the cylinder 11 is fixedly connected to the bottom of the extrusion plate 10. When the cylinder 11 is started, the piston on the cylinder 11 can push the extrusion plate 10, so that the extrusion plate 10 rises or falls, so that the rubber band raw material can be cut by the blade 8 again and again. A limit frame 14 is fixedly connected in the vulcanization box 1. The side of the limit frame 14 close to the extrusion plate 10 is flush with the end of the blade 8. The limit frame 14 limits the position where the extrusion plate 10 is lifted, so that the extrusion plate 10 will not directly contact the blade 8, making it difficult for the blade 8 to be damaged.

[0025] An opening 12 is provided on the extrusion plate 10 , to which an end cap 13 is detachably connected. The end cap 13 is made of rubber and can be fitted with the bottom surface of the extrusion plate 10 . After cutting and vulcanization, the end cap 13 can be opened to take out the vulcanized rubber band raw material from the opening 12 .

[0026] The bottom of the vulcanization box 1 is slidably connected with a rake 15 through a driving member, and the bottom of the rake 15 abuts against the top of the extrusion plate 10. The driving member includes a threaded rod 17 and a connecting block 18. The connecting block 18 is fixedly connected to the side of the rake 15. A motor 2 19 is fixedly connected to the outer wall of the vulcanization box 1. The output end of the motor 2 19 is fixedly connected to one end of the threaded rod 17. The side wall of the connecting block 18 abuts against the inner wall of the groove 20. By starting the motor 2 19, the motor 2 19 drives the threaded rod 17 to rotate. Due to the connecting block 18 The side wall of the groove 20 abuts against the inner wall of the groove 20, and the connecting block 18 does not rotate. Therefore, the threaded rod 17 can drive the connecting block 18 to move forward and backward during the rotation, thereby driving the nail rake 15 to move forward and backward. When the extrusion plate 10 is located at the bottom of the vulcanization box 1, the nail rake 15 can slide back and forth on the surface of the extrusion plate 10, thereby turning over the rubber band raw material, so that the rubber band raw material in the middle can move to the side, so that it can be fully contacted with the steam during the vulcanization process, so that the rubber band raw material can be vulcanized more fully.

[0027] A receiving groove 16 for placing the nail rake 15 is provided in the vulcanization box 1, and a groove 20 for accommodating the threaded rod 17 is provided in the vulcanization box 1. By providing the receiving groove 16 and the groove 20, the nail rake 15 and the threaded rod 17 will not interfere with the extrusion plate 10 during the normal movement of the extrusion plate 10, so that the extrusion plate 10 can work normally.

[0028] The normal use of this utility model is as follows:

[0029] Before the rubber band raw material is vulcanized, the rubber band raw material can be put in from the top of the vulcanization box 1, and then the required vulcanizing agent is added to the mixing box 3. After the raw material is added, the connecting plate 4 is closed to start the process. During vulcanization, the motor 9 is started first to drive the gear 6 to rotate. Since the gear 6 and the gear 2 7 are meshed with each other, the gear 2 7 can be driven to rotate, thereby driving the rotating rod 5 and the blade 8 to rotate, and the rubber band raw material is cut. Then the cylinder 11 is started, and the piston on the cylinder 11 can push the extrusion plate 10, thereby controlling the extrusion plate 10 to rise or fall, so that the rubber band raw material can be cut by the blade 8 again and again, and the steam engine 2 is started to start vulcanization. In this process, when the extrusion plate 10 is located at the bottom of the vulcanization box 1, the motor 2 19 is started, and the motor 2 19 can drive the threaded rod 17 to rotate, thereby driving the connecting block 18 and the rake 15 to move, so that the rubber band raw material can be turned over and stirred. After the turning over and stirring is completed, the cylinder 11 is restarted so that the rubber band raw material can be fully vulcanized.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
