Description

Technical Field

[0001] The utility model relates to the technical field of belt processing, and specifically relates to a slitting device for belt processing. Background Art

[0002] In the production process of belts, in order to cut leather and quickly cut the leather into strips, a leather slitting device is required.

[0003] At present, when the existing slitting device for belt processing is in use, there are still the following deficiencies: 1. When cutting leather, there is a lack of a tensioning structure to tension the leather, resulting in easy shear deviation due to incomplete tensioning of the leather during cutting; 2. There is a lack of a dust removal structure. Fine debris will be generated during the cutting of leather. The fine debris floats in the air and is inhaled by the staff during long-term breathing, causing damage to the body. In view of this, we propose a slitting device for belt processing to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a slitting device for belt processing to solve the problems mentioned in the above background art.

A first driving motor is fixedly installed on the installation frame, and the output end of the first driving motor is in transmission connection with the rotating cylinder. A plurality of annular cutting knives are installed on the rotating cylinder.

[0007] Preferably, a dust collector is fixedly installed on the bottom wall of the box body. A U-shaped air inlet pipe is fixedly installed on the dust collector. One end of the U-shaped air inlet pipe away from the dust collector is fixedly installed with a dust suction hood. The dust suction hood is fixedly installed in the inner cavity of the box body, and the dust suction hood is arranged below the rotating cylinder.

[0008] Preferably, an exhaust pipe is fixedly installed on the dust collector, and a dust collection cloth bag is fixedly installed on the exhaust pipe.

[0009] Preferably, two linkage boxes are fixedly installed on the front side wall of the box body. A pair of meshing gears are arranged in each of the two linkage boxes. A rotating rod is fixedly installed on the gear, and the rotating rod is fixedly connected to the rotating shaft. Second driving motors are fixedly installed on the outer walls of the two linkage boxes, and the second driving motors are in transmission connection with one rotating rod.

[0010] Preferably, an L-shaped support frame is fixedly installed on the top wall at the rear side of the base and located on the box body. A hydraulic rod is fixedly installed on the L-shaped support frame, and the bottom end of the hydraulic rod is fixedly installed on the top wall of the box cover.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the leather of the present utility model is sheared, two second driving motors and two pairs of gears are arranged to drive two pairs of conveying rollers at both ends of the annular cutter to drive the leather for conveying, so that the leather can maintain sufficient tension during the shearing process, avoiding the problem that the leather is prone to shearing deviation due to incomplete tension during shearing, and ensuring the quality of leather strip processing;

[0013] 2. The box body and the box cover provided by the present utility model can prevent the fine chips generated during shearing from flying. The dust collector can make the suction hood generate negative pressure air suction through the U-shaped air inlet pipe, so that the fine chips generated during leather shearing are sucked into the suction hood by the air and discharged into the dust collection cloth bag through the exhaust pipe for collection, solving the problem that the fine chips flying during shearing cause damage to the bodies of the staff.
