A trimming groove for leather to enter is formed in the inner side of the trimming part, a cutting edge part located in the trimming groove and a waste opening corresponding to the cutting edge part in position are arranged on the trimming part, the two sides of the leather can be trimmed through the trimmer, it is guaranteed that the sizes of the trimmed leather are consistent, and the trimming effect is improved.

The utility model discloses a round strip twisting machine for leather decoration belts, which comprises a fixing plate, an adjusting channel is transversely arranged in the middle of the fixing plate, a plurality of adjusting blocks are arranged in the adjusting channel, a shaft rod is arranged at the center of each adjusting block, and a first polishing piece and a second polishing piece are sleeved on each shaft rod up and down. The opposite faces of the first polishing piece and the second polishing piece are sunken to form polishing grooves of an annular structure, upper positioning shells are arranged on the two sides of the first polishing piece, lower positioning shells are arranged on the two sides of the second polishing piece, the upper positioning shells and the lower positioning shells are combined to form positioning grooves, and the positioning grooves are combined to form a positioning channel for the decorative belt to pass through. The leather strip polishing device is simple in structure, the distance between the first polishing piece and the second polishing piece can be adjusted according to the width of a leather strip, the distance between the first polishing piece and the second polishing piece can be changed through the first adjusting mechanism so as to adapt to different thicknesses, and adaptability is improved.

The utility model relates to the technical field of leather, and discloses a rear end cover alignment tool which comprises a machine body mechanism and a supporting table, fixing rods are fixedly connected to the four corners of the upper top end of the supporting table, and a top plate is fixedly connected to the upper top ends of the fixing rods.

This invention discloses a leather flanging device and method for injection-molded parts, including a base, a positioning fixture mounted on the base, a flanging mechanism mounted on the base for flanging the product on the positioning fixture, and a clamping mechanism mounted on the base for pressing the product on the positioning fixture. Advantages: The entire device can first clamp the injection-molded part using the clamping mechanism, and then use the flanging mechanism to flanging the leather edge of the injection-molded part. This effectively ensures the stability of the entire injection-molded part during flanging, thereby improving the efficiency of leather flanging. The entire clamping mechanism is divided into a first clamping component and a second clamping component, which are located at both ends of the positioning groove, respectively, and position and clamp the two ends of the injection-molded part. This ensures that the two ends of the injection-molded part do not warp during the leather flanging process, thus ensuring smooth leather flanging.
