Technical Field

[0002] Automobile sealing strips are sealing materials used in different parts of the car body, usually made of rubber or plastic products, which play the role of waterproofing, sound insulation, dustproofing and improving the sealing performance of the vehicle. They can be installed in doors, hoods, trunk lids, windows and other locations to ensure the comfort and safety of the vehicle during driving.

[0003] Through searching, it is found that CN218504670U relates to a slitting machine for sealing rubber strips, including a main machine, a baffle and a piston rod, a conveyor belt is installed on the upper end of the main machine, and a rotating shaft is connected to one side of the conveyor belt, a motor is arranged at one end of the rotating shaft, and a support plate is installed at the bottom of the motor, baffles are arranged on both sides of the upper end of the main machine, and piston rods are arranged at one end of the baffles, cylinder sleeves are sleeved at one end of the piston rods, and telescopic cylinders are arranged at one end of the cylinder sleeves. The utility model overcomes the shortcomings of the prior art, and by setting a piston rod and a telescopic cylinder, in the process of the conveyor belt transmitting the rubber strips to the slitting, the piston rod is driven by the telescopic cylinder to move left and right in the cylinder sleeve, and then the piston rod drives the limit plate to move left and right together to limit and fix the sealing rubber strips of different sizes, and this process prevents the rubber strips from being skewed and displaced during the transmission process, so that the rubber strips finally cut out are flat and uniform.

[0004] However, due to the different shapes of the strips, the two limiting plates are closed together to limit the special-shaped sealing strips, but the limiting effect is poor, resulting in the sealing strips still being rotated and twisted during the conveying process, resulting in uneven cuts of the sealing strips, affecting the overall quality of the sealing strips. Therefore, we need a strip slitting machine for sealant production. Utility Model Content
