Abstract
Description
Technical Field
[0001] The utility model relates to a cutting device, in particular to a cutting device for producing denim fabrics. Background Art
[0002] There are obvious differences between denim fabric and ordinary fabric in terms of raw material composition, organizational structure, weaving method and finishing process. These differences make denim fabric have a unique appearance and feel, suitable for making various clothing and accessories. Denim fabric needs to go through a cutting process during the production process, and the denim fabric is cut from a continuous strip to the required size. Existing fabric cutting equipment generally consists of a cutting platform, a fabric supply component, a fixed clamping component, a cutting component and a mobile clamping component that slides horizontally along the front and back directions of the cutting platform. The fabric supply component supplies fabric to the fixed clamping component, and the mobile clamping component can clamp the fabric from the fixed clamping component and move backward. After moving to a preset length, the cutting component cuts the fabric. The cutting method is to move and cut perpendicular to the length direction, so the fabric is slowly and completely cut off. During the cutting process, the cut fabric will sag, and the drooping fabric will exert a certain tension on the fabric in the cutting area. The fabric has a certain elasticity. As the tension increases, the fabric in this area will expand and contract. This will cause a slight deviation between the actual cutting line and the set cutting line. For the specific deviation trend, please refer to the attached figure in the specification. Figure 6 . Summary of the invention
[0003] The utility model provides a cutting device for producing denim fabrics, which solves the problem in the prior art that there is a slight deviation between the actual cutting line of the fabric and the preset cutting line.

[0005] The operation process of the utility model is as follows: the fixed clamping component clamps the denim fabric from the fabric supply component, the mobile clamping component moves toward the fixed clamping component and clamps the head of the denim fabric thereon, then the fixed clamping component releases the denim fabric, and at the same time the mobile clamping component moves backward a fixed distance, then the negative pressure adsorption plate turns on the negative pressure adsorption state, and the denim fabric on the lower side thereof will be adsorbed and fixed to the bottom of the negative pressure adsorption plate, in order to avoid generating more pulling force on the fabric, the bottom of the negative pressure adsorption plate is nearly consistent with the height of the fabric to be cut, then the transverse reciprocating movement mechanism on the cutting component drives the cutter to cut the fabric, after the cutting is completed, the cutter resets, the mobile clamping component releases the fabric or moves backward a certain distance and then releases the fabric, at the same time the negative pressure adsorption plate disconnects the adsorption, and the cut denim fabric falls into a fixed area on the cutting platform.
[0006] Furthermore, the negative pressure adsorption plates are distributed in multiple rows, and channels for the lower hanging parts to pass through are formed between each row of negative pressure adsorption plates.
[0007] Furthermore, the cutter is a cutting blade or a laser cutting head.
[0008] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The negative pressure adsorption plate is turned on the negative pressure adsorption state, and the denim fabric on the lower side thereof will be adsorbed and fixed to the bottom of the negative pressure adsorption plate, and then the lateral reciprocating movement mechanism on the cutting component drives the cutter to cut the fabric. During the fabric cutting process, the fabric is in a state of being adsorbed by the negative pressure adsorption plate, and there is almost no hanging phenomenon of the fabric after being cut, so the fabric cutting accuracy is relatively high.

The transverse reciprocating mechanism includes a horizontal transverse slide rail 420 and a slide table 430 slidably mounted on the transverse slide rail, and the slide table is driven to reciprocate by a belt; the fabric supply component can convey the denim fabric 10 to the fixed clamping component, and the mobile clamping component can draw out the denim fabric on the fixed clamping component, and the drawn out denim fabric is the denim fabric to be cut; the lower surface of the negative pressure adsorption plate is horizontally arranged and located on the upper side of the denim fabric to be cut, and a plurality of densely distributed negative pressure holes 510 are provided on the bottom surface of the negative pressure adsorption plate, and the negative pressure holes are connected to the negative pressure equipment through pipelines.
[0018] See Figure 2 and Figure 4 The mobile clamping assembly includes a slide rail 610 fixed on the cutting platform, a sliding hanger 620 slidably mounted on the slide rail, a driver 630 driving the sliding hanger to move back and forth along the slide rail, a lower hanging part 640 extending downward from the sliding hanger, and a gripper module 650 arranged at the bottom of the lower hanging part, wherein the driver is a belt driven by a motor. The gripper module is specifically a gripper cylinder. The belt is driven by the motor to rotate forward and reverse, thereby driving the sliding hanger to move back and forth along the slide rail.
[0019] See Figure 3The fixed clamping assembly includes a front hanger 310 fixed on the upper side of the cutting platform, an upper clamping plate 320 horizontally fixed below the front hanger, two clamping cylinders 330 vertically fixed on the upper clamping plate, and a lower clamping plate 340 located at the lower side of the upper clamping plate.
