Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, specifically to a two-roll mill for processing rubber products. Background Technology

[0002] The open mill is one of the earliest plastic mixing equipment used in plastic product manufacturing plants. On the calendering production line, the open mill is placed before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, providing a more uniformly mixed molten material for the calendering and molding of plastic products.

[0003] Publication No. CN218948133U discloses an open mill for processing rubber products. This mill, through the cooperation of a drive motor, facilitates control of the distance between the base frame and the extension frame, thereby increasing the material storage capacity. However, during operation, this equipment requires workers to manually load auxiliary materials, trim and cut them, posing certain safety hazards. Furthermore, manual operation is time-consuming, labor-intensive, and relatively inefficient. Therefore, we propose an open mill for processing rubber products. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a two-roll mill for processing rubber products.

[0005] The technical solution adopted by this utility model to solve its technical problem is a rubber product processing open mill, including a bottom base. A first motor and a second motor are respectively installed on the side wall of the bottom base. The power output ends of the first motor and the second motor are respectively installed with a first rubber mixing roller and a second rubber mixing roller through the side wall of the bottom base. A limiting rotation groove is opened in the side wall of the bottom base. An electric scraper is rotatably connected inside the limiting rotation groove. The two ends of the electric scraper are fixedly connected to limiting clips inside the limiting rotation groove.

[0006] A top base is fixedly connected to the top of the bottom base. A fixing rod is connected through the inner wall of the top base. A pressure base is installed on the outer wall of the fixing rod. A material conveying pipe is connected through one side of the top of the pressure base. The end of the material conveying pipe away from the pressure base is connected through to one end of an external pipe.

[0007] By adopting the above technical solution, the rubber product is first placed on the surface of the first mixing roller. Driven by the first and second motors on the side wall of the bottom base, the first and second mixing rollers drive the rubber product to start mixing. At the same time, the auxiliary roller inside the top base extends towards the first mixing roller and the second motor through the electric lifting rod, and then works with the first mixing roller and the second motor to start mixing the rubber. During the processing, the transfer base made on the surface of the fixed rod receives the auxiliary material conveyed through the external pipe and the conveying pipe, and sprays it onto the rubber product being mixed from the spray bar. After the processing is completed, the motor controlling the rotation of the electric scraper on the side wall of the bottom base runs, so that the electric scraper rotates at a certain angle under the restriction of the limiting rotation groove and the limiting clamp, thereby adhering to the surface of the first mixing roller to scrape off the processed rubber product.

[0008] Specifically, a spray bar for spraying auxiliary materials is connected through the bottom end of the pressurized base.

[0009] By adopting the above technical solution, auxiliary materials are sprayed onto rubber products using a spray bar.

[0010] Specifically, a pressurization device is provided at the connection point between the external pipe and the bottom base.

[0011] By adopting the above technical solution, the auxiliary materials can be sprayed onto the surface of the open-milled rubber through a spray bar using a pressurizing device.

[0012] Specifically, the inner walls on both sides of the top base are provided with auxiliary rollers that slide via an electric telescopic rod.

[0013] By adopting the above technical solution, rubber products are processed by the first and second rubber mixing rollers through adjustable auxiliary rollers.

[0014] Specifically, a control motor is provided at one end of the electric scraper that passes through the side wall of the bottom base.

[0015] By adopting the above technical solution, the angle of the electric scraper can be quickly adjusted by controlling the motor, thereby freely controlling the scraping of rubber products.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This technical solution, through the design of a bottom base, a limiting rotation groove, an electric scraper, a limiting clamp, a top base, a fixing rod, a transfer base, a spray rod, a conveying pipe, and an external pipe, firstly places the rubber product on the surface of the first mixing roller. Driven by the first and second motors on the side wall of the bottom base, the first and second mixing rollers drive the rubber product to begin mixing. Simultaneously, the auxiliary roller inside the top base extends towards the first mixing roller and the second motor via an electric lifting rod, thus cooperating with the first and second mixing rollers to mix the rubber. During processing, the transfer base formed on the surface of the fixing rod receives auxiliary materials conveyed through the conveying pipe via the external pipe and sprayed onto the mixing rubber product from the spray rod. After processing is completed, the motor controlling the rotation of the electric scraper on the side wall of the bottom base operates, causing the electric scraper to rotate at a certain angle under the restriction of the limiting rotation groove and the limiting clamp, thereby adhering to the surface of the first mixing roller to scrape off the processed rubber product. This reduces the amount of manual labor, lowers the probability of accidents, and improves processing efficiency compared to manual assistance. Attached Figure Description
