Description

Technical Field

[0001] The utility model relates to the technical field of rubber vulcanization devices, in particular to a continuous vulcanization device in the production of recycled rubber. Background Art

[0002] In the rubber production process, vulcanization is an important step, which determines the physical and chemical properties of rubber products. When vulcanizing recycled rubber, it is usually carried out in a corresponding vulcanizing device. There are many types of vulcanizing devices on the market, and most of them are equipped with a vulcanizing chamber. In specific operations, the recycled rubber is transported to the vulcanizing chamber through a conveying component for vulcanization.

[0003] Since the conveying assembly is used for conveying, this type of vulcanization chamber is generally provided with a feed hole and a discharge hole, and the conveying assembly generally uses a conveyor belt for conveying, and the conveyor belt is inserted from the feed hole and passes through the discharge hole. At this time, since the conveyor belt occupies the feed hole and the discharge hole, most vulcanization chambers lack components that can block the feed hole and the discharge hole, which is not conducive to relative sealing operations, and easily causes gas leakage during the vulcanization process, polluting the external air and causing inconvenience to users. In view of this, we propose a continuous vulcanization device for recycled rubber production. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a continuous vulcanization device in the production of recycled rubber, comprising a vulcanization chamber 1, material holes 10 are arranged on the plates at both ends of the vulcanization chamber 1, end frames 13 are fixedly installed on both ends of the vulcanization chamber 1, a rotating shaft 14 is rotatably connected between the plates at the front and rear sides of the end frames 13, and conveyor belts 15 are sleeved on the two rotating shafts 14, a driving motor 151 is coaxially arranged at the end of one of the rotating shafts 14, the output shaft end of the driving motor 151 is fixedly installed on the rotating shaft 14, and the driving motor 151 is fixedly installed on the end frame 13, so that the driving motor 151 can be used to drive the conveyor belt 15 to rotate for conveying operation;

[0028] Specifically, a plurality of elastic components 2 arranged linearly and equidistantly are provided on the bottom surface of the bottom plate of the vulcanization chamber 1, and the elastic component 2 includes a storage sleeve 20 fixedly installed on the bottom surface of the bottom plate of the vulcanization chamber 1, and a guide block 21 is slidably connected in the storage sleeve 20, and a spring 22 is fixedly installed between the guide block 21 and the top wall of the storage sleeve 20, and a support roller 23 is rotatably connected to the guide block 21, and the support roller 23 is against the inner surface of the lower belt body of the conveyor belt 15. Cylinders 3 are fixedly installed on the side surfaces of both ends of the vulcanization chamber 1, and a sealing plate 31 is provided on the telescopic shaft of the cylinder 3, so as to facilitate the sealing operation of the material hole 10 by using the sealing plate 31.

[0029] In this embodiment, a lower pressure plate 32 is fixedly installed on the side of the sealing plate 31. The lower pressure plate 32 is located in the material hole 10 and is slidably connected to the material hole 10. This ensures that when in use, as the sealing plate 31 moves downward, it can drive the lower pressure plate 32 to squeeze the upper half of the conveyor belt 15 onto the bottom wall of the vulcanization chamber 1, thereby achieving better and more comprehensive sealing and plugging operations.

[0030] In this embodiment, the conveyor belt 15 passes through the material hole 10, and the upper and lower belt bodies of the conveyor belt 15 are respectively located on the upper and lower sides of the bottom plate body of the vulcanization chamber 1, so that the upper belt body of the conveyor belt 15 can move along the inner surface of the bottom plate body of the vulcanization chamber 1, and at the same time, the sealing plate 31 is against the upper half of the belt body of the conveyor belt 15, and the sealing plate 31 slides along the side of the vulcanization chamber 1. After the sealing plate 31 moves downward until the bottom surface is against the upper surface of the conveyor belt 15, the material hole 10 can be sealed.

[0031] Specifically, a plurality of infrared heaters 11 arranged linearly and equidistantly are fixedly installed between the inner walls on the front and rear sides of the vulcanization chamber 1 , and the infrared heaters 11 are used for heating operation.

[0032] Furthermore, a plurality of support legs 12 arranged in a matrix are fixedly mounted on the bottom surface of the vulcanization chamber 1 , and the support legs 12 are used for supporting operations.

[0033] In addition, the size of the guide block 21 is adapted to the size of the storage sleeve 20 for stable sliding operation.

[0034] It is worth noting that a rectangular plate 30 is fixedly mounted at the end of the telescopic shaft of the cylinder 3 , and a blocking plate 31 is fixedly mounted on the bottom surface of the rectangular plate 30 by a plurality of fastening screws, so as to facilitate the fixed installation operation of the blocking plate 31 .

[0036] When the continuous vulcanization device in the production of recycled rubber of the utility model is used, the cylinder 3 is first started and made to work. When the cylinder 3 works, the telescopic shaft on it is extended to drive the blocking plate 31 to move upward. At this time, the blocking plate 31 no longer blocks the material hole 10. The drive motor 151 is connected to the external power supply and made to work. When the drive motor 151 works, the output shaft on it rotates to drive the rotating shaft 14 to rotate, and further drives the conveyor belt 15 to rotate, so as to transport the recycled rubber on the conveyor belt 15 to the vulcanization chamber 1 for vulcanization operation. In addition, as the recycled rubber enters the vulcanization chamber 1, the cylinder 3 is started and made to work. When the cylinder 3 works, the telescopic shaft on it is extended to drive the blocking plate 31 to move downward to block the orifice of the material hole 10. At the same time, the lower pressing plate 32 squeezes the upper half of the conveyor belt 15 onto the bottom wall of the vulcanization chamber 1 to complete the sealing operation and reduce leakage.

[0037] When the vulcanization of the batch of regenerated rubber is completed, the sealing plate 31 moves upward, and the conveyor belt 15 continues to rotate, so as to transport the vulcanized regenerated rubber outward, and at the same time, the unvulcanized regenerated rubber continues to be transported into the vulcanization chamber 1, so as to realize continuous vulcanization operation.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
