Description

Technical Field

[0001] This utility model relates to the technical field of rubber strip cutting machines, specifically to an adjustable rubber strip cutting machine. Background Technology

[0002] Rubber strips are a common type of rubber component. Their production typically requires a strip-cutting machine to cut the rubber raw material into strips. A typical strip-cutting machine includes a cutting blade to cut the rubber raw material and a conveyor roller to transport the material. The conveyor roller moves the rubber raw material forward a short distance each time, then pauses, allowing the cutting blade to move downwards and cut out the rubber strip.

[0003] For example, the utility model disclosed in CN218965488U discloses a rubber strip cutting machine, including an operating table and a strip cutting mechanism set on the upper part of the operating table. The top left and right ends of the operating table are provided with limit plates through support columns. The top of the limit plate is provided with a cylinder. The output end of the cylinder passes through the limit plate to set the strip cutting mechanism. The strip cutting mechanism includes an I-shaped support plate. The left and right ends of the I-shaped support plate are respectively provided with a pair of left sliding holes and a pair of right sliding holes. By starting the cylinder, the cylinder pushes the strip cutting mechanism to move downward. When the two pressure plates are pressed against the two ends of the rubber, the sliding rod on the upper part of the pressure plate slides upward inside the sliding hole of the I-shaped support plate. At this time, the spring is compressed, and the spring exerts a downward elastic force on the pressure plate, thereby limiting the pressure plate to the rubber. The cylinder continues to move, and finally performs the strip cutting operation on the rubber. Because the two pressure plates limit the rubber on the left and right sides of the cutter, the problem of poor cutting effect caused by rubber displacement during the strip cutting process is prevented, and the next rubber strip cutting operation is not affected.

[0004] In the process of developing this application, the following problems were found in the technology: the spacing of the cutting blades of the existing rubber strip cutting machines is mostly not adjustable, which makes it impossible for the device to cut rubber strips of different widths. Moreover, the existing rubber strip cutting machines cannot adjust the length of the rubber strips, which reduces the adaptability of the device.

[0005] Therefore, an adjustable rubber strip cutter is proposed. Utility Model Content
