Abstract

The invention discloses a pocket hole slashing device of a laser pocket machine. The pocket hole slashing device of the laser pocket machine comprises an operation platform, a machine head, a laser cutting assembly, a cloth clamping and moving mechanism and an upper air suction assembly. A laser pipe is fixed into a laser pipe frame fixed to the lower side of the operation platform. The lower endof a laser guide pipe is connected with the laser pipe. The top of the laser guide pipe is connected with the laser cutting head. A laser cutting opening is formed over the top of the laser cutting head and located on the operation platform. The upper air suction assembly comprises a fixing seat, a lifting mechanism, a laser protective plate, an upper air suction hard pipe, an upper air suction hose and an air suction barrel, wherein the upper air suction hard pipe is fixed to the laser protective plate. The laser protective plate is connected with a lifting mechanism. One end of the upper airsuction hard pipe is an air suction opening. The air suction opening is located over the laser cutting opening. The other end of the upper air suction hard pipe is connected with the air suction barrel through the upper air suction hose.

Description

technical field [0001] The invention belongs to the field of sewing equipment, and in particular discloses a notch opening device for a laser bag opening machine. Background technique [0002] With the development of laser cutting technology, more and more laser cutting technology is used to replace the traditional blade cutting method in the cloth cutting of the garment industry. The current laser cutting technology is becoming more and more mature, and the cloth laser cutting device is widely used in the market due to its advantages of high cutting efficiency, convenient use, and superior cutting effect. [0003] The existing cloth laser cutting device is mainly composed of a laser generator, a laser cutting head and a light guide pipe, and due to the limitation of the structure, the following defects are caused: [0004] (1) Usually, the space of the garment production workshop is relatively closed, and the staff are many and concentrated.

AI Technical Summary

Problems solved by technology

[0004] (1) Generally, the space of the garment production workshop is relatively closed, and the staff are many and concentrated. During the process of laser cutting the fabric, a large amount of smoke will be generated, which not only affects the operating vision, but is more likely to cause harm to the human body

(2) Since the laser cutting head is set above the worktable, in order to facilitate feeding without affecting the normal cutting, there is a large distance between the laser cutting head and the cloth to be cut, which leads to a relatively large incision. Rough, thick cut, easy to cause whitening and hardening of the fabric

(3) Since the existing laser cutting head is installed above the operating table, this will inevitably lead to the cutting method of the existing laser cutting head from top to bottom. Due to the limitation of the range of sewing equipment and the limitation of traditional sewing methods, As a result, the laser cutting head is too close to the operator's hand, which is likely to cause safety hazards. At the same time, the operator needs to adjust the fabric during the operation, and often touches the laser cutting head inadvertently, resulting in deviation of the laser cutting head. Position and cutting errors affect the cutting accuracy and do not meet the processing requirements of high-end clothing

[0005] In order to improve the operation convenience of the laser cutting device, the Chinese invention patent application with the publication number CN 107326552 A and the application number 201710723845.7 discloses a laser cutting placket machine, which mainly consists of a sewing machine head arranged on the same transmission part, Composed of a laser part and a frame, the transmission part, sewing machine head and laser part are all set above the table, and the laser part moves back and forth with the transmission part to cut the cloth. The advantage is that the cloth can be cut automatically during the cutting process. Reduce the working intensity of the staff; but the disadvantage is that when the laser parts move with the transmission parts, it is easy to cause cutting errors and affect the cutting accuracy due to reasons such as vibration; A safety accident occurs to personnel; the transmission part is mainly composed of a screw rod, a screw nut, a mounting plate and a motor, and the laser head mounting frame of the laser part is mainly composed of a first beam and a longitudinal beam, and the whole device has many parts , The structure is relatively complex, and it is prone to component wear and tear during use, shortening the service life, and at the same time, increasing equipment costs and maintenance costs

And because the transmission parts are arranged on the table, it takes up a lot of space above the table, and the structure is unreasonable, which is very inconvenient for feeding and affects the cutting efficiency of the cloth.

[0006] In the prior art, the laser cutting head is also arranged under the workbench. For example, the invention patent with the authorized announcement number of CN206869321U and the application number of 201720734483.7 discloses a laser cloth cutting device for a sewing machine. Its laser generator and guide The light pipe is fixed at the bottom of the table, which solves the problem that the installation space is too high. The effect is to reduce the installation space and make the installation space more reasonable; however, the reflective structure of the light pipe is relatively complicated, requiring multiple reflector structures and multiple It is not very convenient for installation or maintenance; at the same time, the device also includes an upper suction hood and a lower suction hood, and the lower suction hood fixes the top of the light guide tube to The laser cutting head is enclosed inside, and the working gap between the laser cutting head and the worktable is relatively large, so that the smoke generated by cutting the cloth is easy to overflow during the operation; the function of the upper suction hood of the device is to prevent the laser from shooting to the staff, but in actual operation, the upper suction hood is very easy to be touched by the staff, resulting in offset and affecting the actual use effect
