Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, and in particular to a rubber powder cooling and circulation device. Background Technology

[0002] In the production and processing of rubber products, the cooling treatment of rubber powder is a crucial step, as its cooling effect directly affects the subsequent processing quality and product performance. Currently, rubber powder cooling equipment on the market has many shortcomings in practical applications. For example, most equipment struggles to flexibly control the rotation and braking state of the cooling drum, resulting in poor operational convenience and reduced work efficiency. This is especially true during the discharge stage, where untimely drum state transitions or unstable braking often increase operational difficulty. Furthermore, the rubber powder's mixing within the cooling drum is insufficient, leading to localized inadequate cooling and failing to guarantee optimal cooling results. In addition, the unloading process often relies on manual assistance, which is not only inefficient but also increases labor costs. Moreover, the overall equipment structure is not compact or rationally designed, with poor coordination between components, resulting in insufficient equipment stability and reliability, a short service life, and an inability to meet the demands of large-scale production.

[0038] Multiple arc-shaped plates 24 arranged in parallel to each other are fixedly installed on the inner walls of both sides of the cooling drum 2, which can perform a stirring operation on the rubber powder as the cooling drum 2 rotates.

[0039] A support bar 231 is radially fixedly installed on the rotating shaft 22.

[0040] A hollow ring 61 is rotatably sealed on one side of the cooling drum 2, and two conveying pipes 62 are fixedly installed on the hollow ring 61. A cooling pipe 6 connected to the hollow ring 61 is fixedly installed on the inner wall of one side of the cooling drum 2, and the cooling pipe 6 is set with the conveying drum 21 as the center.

[0042] In this embodiment, in order to provide shielding and protection for components such as motor 3, upper gear 32, lower gear 33 and drive gear 31, a protective cover is fixedly installed on one side of the support frame 1, and motor 3, upper gear 32, drive gear 31 and lower gear 33 are all located inside the protective cover.

[0043] In this embodiment, in order to enable the rubber powder entering the cooling drum 2 to disperse quickly, the conveying drum 21 is provided with multiple discharge holes.

[0044] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0045] Working principle: In use, first connect the power supply and start the motor 3. The motor 3 drives the drive gear 31 to rotate. The drive gear 31, through meshing with the upper gear 32, causes the spiral blades 221 on the rotating shaft 22 to start rotating. At the same time, the lower gears 33 and 34 respectively cooperate with the drive gear 31 and the gear disc 35 to transmit power to the cooling drum 2 and control its rotation. During the cooling process, rubber powder enters the conveying drum 21 from the feed hopper 25 and is pushed to the cooling drum 21 by the action of the spiral blades 221. Inside the rotating drum 2, the rubber powder is allowed to fall downwards by scattering due to the multiple discharge holes on the conveying drum 21. The cooling pipe 6 introduces the cooling medium through the hollow ring 61 and the conveying pipe 62 to cool the rubber powder. At the same time, multiple arc plates 24 continuously tumble the rubber powder as the cooling drum 2 rotates, ensuring that the material is heated evenly. The spiral blades 23, driven by the rotating shaft 22, not only assist the material in moving laterally inside the cooling drum 2, but also provide additional thrust during unloading, improving unloading efficiency.

[0046] When unloading is required after cooling is complete, the lifting plate 331 is controlled to move downward by the electric cylinder 332, so that the drive gear 31 and the lower gear 33 disengage. At the same time, the lifting plate 331 controls the brake block 41 to approach and abut against the brake ring 4, so that the cooling drum 2 can be braked when the discharge port moves to the lowest position. The downward movement of the lifting plate 331 will control the left toothed plate 5 to move downward synchronously. With the cooperation of the left gear 52, the toothed plate 51 and the right toothed plate 5, the bracket 54 is controlled to move upward and drive the unloading plate 201 to move upward through the fixing pin. Thus, the discharge port can be opened at the same time as the cooling drum 2 is braked. Then, by adjusting the rotation direction of the motor 3, the spiral blade 23 is controlled to push the rubber powder in the cooling drum 2 to the right, so as to facilitate the rapid unloading operation.

[0047] The above provides a detailed description of the rubber powder cooling and circulation device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
