Description

Technical Field

[0001] This utility model relates to the field of calendering equipment technology, and more specifically, to a three-roll calendering device for the production of motorcycle inner tubes. Background Technology

[0002] Because rubber has high elasticity and high elongation, which are not found in any other material, it is widely used in various sectors of the national economy, national defense, space development, and daily life. Motorcycle tires are one of the products made primarily of rubber.

[0003] In the existing technology, a three-roll calender is required to calender rubber during the production of motorcycle inner tubes. However, due to the structural design of the existing calender, the surface of the rollers often becomes sticky with raw material residues and other impurities after long-term use, which affects the subsequent rubber calendering effect. In addition, the surface temperature of the rollers will rise after long-term use, which will affect the molding quality of the rubber in subsequent processing. If natural cooling is used, the cooling time is long and it will affect the processing efficiency of motorcycle inner tube production.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a three-roll calendering device for the production of motorcycle inner tubes, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A three-roll calendering apparatus for producing motorcycle inner tubes includes a frame on which the three-roll calendering apparatus body is mounted. A support frame is fixedly connected to the top of the frame, and a roller cleaning mechanism is provided on the support frame. Dust collection grooves are symmetrically arranged on the inner wall of the frame. A gas collection hood is installed on the rear side of the dust collection groove. A guide pipe is connected to the gas collection hood, and a collection box is connected to the gas collection hood through the guide pipe. The collection box is fixed to the frame, and fans are installed at equal intervals on the collection box. Both the inner cavity of the collection box and the gas collection hood are provided with partitions.

[0008] Preferably, the roller cleaning mechanism includes a drive assembly, a water tank, a water pump, a connecting pipe, a mounting plate, a hydraulic cylinder, a connecting frame, a scraper, and a spray pipe. The drive assembly includes a fixed frame, a drive motor, a lead screw, and a guide block.

[0009] Preferably, the fixing frame is fixed to the top of the support frame, the lead screw is disposed inside the fixing frame, one end of the lead screw is connected to the drive motor, and the guide block is connected to the lead screw.

[0010] Preferably, the bottom of the fixing frame is provided with a guide groove that matches the guide block, and the guide block passes through the guide groove and is fixedly connected to the mounting plate.

[0011] Preferably, the hydraulic cylinder is fixed to the bottom of the mounting plate, the output end of the hydraulic cylinder is fixed to the connecting frame, the scraper is disposed on the inner walls of both sides of the connecting frame, and the spray pipe is disposed inside the connecting frame.

[0012] Preferably, the water tank is positioned at the top center of the fixed frame, the water pump is positioned on one side of the water tank, one end of the water pump is connected to the inner cavity of the water tank via a pipe, and the other end of the water pump is connected to the spray pipe via a connecting pipe.

[0013] Preferably, the connecting frame is vertically arranged above the rollers of the three-roll calender body, and the spacing between the scrapers is smaller than the diameter of the rollers.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The roller cleaning mechanism can clean the three rollers separately after the calendering device is used to prevent raw material residues from adhering to the rollers. These residues will mix with another set of rubber after cooling, thereby reducing the subsequent rubber calendering effect and affecting the quality of motorcycle inner tube production.

[0016] 2. With the help of the set dust suction trough and collection box, the dust suction trough sucks the debris on the roller into the collection box through the air collection hood and guide pipe during the cleaning of the roller, which facilitates the cleaning of the device. After the roller is cleaned, water is pumped from the water tank by the water pump, and the spray pipe sprays water on the roller, which can quickly cool the roller and facilitate the subsequent processing of the roller.
