Description

Technical Field

[0001] This utility model relates to the field of pure cotton fabric processing technology, specifically to a cutting device for a pure cotton fabric processing machine. Background Technology

[0002] In the field of pure cotton fabric processing, with the continuous growth of market demand and the increasing requirements for product quality, efficient and precise processing is particularly important.

[0003] However, existing pure cotton fabric cutting devices have some shortcomings. During the feeding process, the fabric is often not fed stably, easily resulting in uneven feeding and deviation, affecting subsequent processing. Regarding the conveyor belt, existing conveyor belts are easily damaged by laser cutting, leading to a short lifespan and frequent replacements, increasing costs. For securing the fabric, existing devices may not achieve precise clamping, causing fabric displacement during cutting and reducing cutting accuracy. Furthermore, existing devices may damage the fabric due to improper clamping force. Additionally, the transition from feeding to the cutting conveyor belt may be uneven, with excessive friction, affecting overall processing efficiency and quality.

[0004] Therefore, this solution proposes a cutting device for a pure cotton fabric processing machine to solve the above problems. Utility Model Content

A pressing plate is installed between the piston rod ends of the two stepping cylinders. A strip-shaped perforation is opened in the center of the pressing plate. A horizontal guiding mechanism is installed on the front side of the top of the pressing plate. A laser cutting head is installed at the guiding drive end of the horizontal guiding mechanism. The ends of the laser cutting head are distributed inside the strip-shaped perforation.

[0007] Preferably, a guide connecting table is provided inside the U-shaped mounting frame between the lower feeding clamping roller and the front end of the fabric cutting conveyor belt.

[0008] Preferably, the front and rear ends of the guide connecting table are both configured as arc grooves that are adapted to the opposite ends of the feeding clamping roller and the fabric cutting conveyor belt.

[0010] Preferably, a plurality of metal strips are evenly embedded on the cutting conveyor belt in transverse distribution to cooperate with the laser cutting head.

[0011] Preferably, the transverse guide mechanism specifically includes a transverse electric guide rail installed on the top of the front end of the pressing plate, a sliding block installed on the transverse electric guide rail, and the laser cutting head specifically installed on the sliding block.

[0012] Preferably, the bottom surface of the pressing plate is further provided with an elastic connecting pad and a lowermost pressing gasket.

[0013] Preferably, the two side step cylinders are synchronously started and stopped.

[0014] Preferably, a cutting support plate is installed in the U-shaped mounting bracket, which is located directly below the pressing plate and supported below the top end surface of the cutting conveyor belt.

[0015] The beneficial effects of the utility model are as follows:

[0016] Stable feeding: the two feeding clamp rollers distributed in transverse parallel can clamp and transport pure cotton gray cloth, ensuring the gray cloth to enter the subsequent processing link stably and improving the stability and reliability of feeding.

[0017] Protecting the conveyor belt: a plurality of metal strips are evenly embedded on the cutting conveyor belt in transverse distribution, which have high hardness and wear resistance and can withstand high temperature of laser without being damaged during laser cutting, effectively avoiding damage of laser to the surface of the conveyor belt, prolonging the service life of the conveyor belt and reducing the equipment maintenance cost.

[0019] Protecting the gray cloth: the elastic connecting pad on the bottom surface of the pressing plate can play a buffering role to avoid damage of the gray cloth caused by excessive extrusion of the pressing plate; the pressing gasket can increase the friction between the pressing plate and the gray cloth, further improve the fixing effect of the gray cloth, ensure the cutting precision, and minimize the damage to the gray cloth.

[0020] The cloth conveying is smooth: the guide connection table arranged in the U-shaped mounting frame is designed with circular arc grooves on the front and rear end surfaces, so that the pure cotton cloth is more smooth in the process of conveying from the feeding clamp roller to the cloth cutting conveying belt, and the friction and damage of the cloth are reduced. The top surface of the guide connection table is flush with the horizontal plane of the tangent line of the top end of the feeding clamp roller and the top end surface of the cloth cutting conveying belt, so that the cloth can be smoothly transferred to the cloth cutting conveying belt, and a good foundation is provided for the subsequent cutting work, and the efficiency and quality of the whole processing process are improved.

[0021] In summary, the cutting device of the pure cotton cloth processing machine has remarkable advantages in improving production efficiency, ensuring product quality, reducing equipment maintenance cost, meeting diversified production demand and the like, and provides an efficient, accurate and reliable solution for processing of pure cotton cloth.
