Description

Technical Field

[0001] The present invention relates to the technical field of luggage processing, and in particular to a slitting and edge pressing device for luggage processing. Background Art

[0002] Luggage products play an irreplaceable role in meeting the daily consumption and fashion consumption needs of people. Moreover, with the development of the economy, the consumption of Chinese bags and ornaments increases annually, and luggage is becoming one of the most potential industries after the clothing and textile industries and the footwear industry.

[0003] The basic seam types of luggage leather are as follows: flat seam, lapped seam, divided pressure seam, buttoned pressure seam, spliced seam, edge wrapping seam, rolled edge seam, saddle stitch, etc. Among them, for the divided pressure seam, two pieces of leather are placed face to face, and sewn along one edge from the back at a fixed interval. After sewing, the leather is separated and pressed tightly. The excess seam allowance can be fixed with glue or sewn with a thread. It should be noted that if the leather is thick, the seam allowance part needs to be thinned, that is, trimmed with a small spatula to make the edge leather suitable thickness for folding the edge, that is, folding up the edge of the leather part, so as to sew a line or decorative line at the folded edge part (as Figure 1 shown, S1 sews the two pieces of leather after edge trimming tightly; S2 separates and presses flat the excess divided pressure flanges to both sides; S3 sews the two divided pressure flanges respectively). In the current operation methods, most of them manually fold and press the two edges flat, and then sew the decorative lines on both sides. On the one hand, due to the uneven force applied each time during manual folding, the flanging is uneven. On the other hand, the manual operation method increases the labor intensity of workers. Therefore, in view of the above problems, it is necessary to develop a device for assisting slitting and edge pressing. Summary of the Invention

[0011] Further, the first rotation drive includes: a first motor provided on the edge separating component, and a first gear transmission assembly. The output end of the first motor is in transmission connection with the end of the flattening roller through the first gear transmission assembly.

[0012] Further, a pressure roller that rotates around a horizontal axis is also installed on the working platform. The end of the pressure roller is in transmission connection with a second rotation drive. When rotating, it is used to press the material tightly on the working platform and convey it along the feeding direction.

[0013] Further, the second rotation drive transmission includes: a second motor provided on the working platform, and a second transmission assembly. The output end of the second motor is in transmission connection with the end of the pressure roller after passing through the second transmission assembly.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The device separates and flattens the folded edges of the two sewn edges, facilitating subsequent edge pressing and sewing, replacing manual work, reducing labor intensity, and improving production efficiency.

[0015] 1. In the present invention, the edge separating component can move vertically in the long slot holes to adjust the thickness of the pressed leather, being suitable for the production and processing of different leathers.

[0016] 2. In the present invention, the axis of the flattening rollers is arranged at a 45° angle to the feeding direction. It evenly unfolds and flattens the turned edges on both sides of the two pieces of leather towards both sides, and on the other hand, conveys them along the feeding direction to avoid wrinkling. This angle setting is the most reasonable. Description of the Drawings
