The cutting table can reduce wrinkles when cutting cloth and improve its aesthetics, but there are many operating steps, which increases the workload of the staff.

The technical problem to be solved by the utility model is: how to improve the efficiency of cutting cloth multiple times, and how to collect the finished products and waste materials after cutting more conveniently.

Utility Model Content

The main purpose of the utility model is to provide a cloth cutting device, which is provided with a receiving roller and a feeding roller to straighten the cloth, a pressing unit to press the edge of the cloth, so that the cloth is close to the conveyor belt unit, and the cutting unit performs cutting on the conveyor belt unit. The conveyor belt unit and the receiving roller rotate synchronously, so that the finished cloth and the waste are collected separately. Secondly, the pressing unit is pressed by a roller. After the cutting is completed, the pressing unit does not need to be loosened, and the receiving roller is directly driven to rotate, which reduces the workload of the staff and improves efficiency.

To achieve the above objectives, the technical solutions adopted in this application are:

A cloth cutting device comprises a fixed frame, a conveyor belt unit for driving the cloth to move forward, a receiving roller, a feeding roller, a pressing unit for pressing the cloth, a cutting unit, and a first driving module for driving the conveyor belt unit and the receiving roller to rotate synchronously; the receiving roller and the feeding roller are respectively connected to the two ends of the fixed frame for rotation; the conveyor belt unit and the cutting unit are both fixed on the fixed frame; a plurality of the pressing units are distributed on both sides of the fixed frame;

The material pressing unit comprises a cross bar, a roller and an elastic adjustment module for enabling the roller to press the cloth; the cross bar is fixed on a fixing frame; the elastic adjustment module is fixed on the free end of the cross bar; and the roller is fixed on the free end of the elastic adjustment module.

Compared with the prior art, this solution has the following beneficial effects:

The fabric cutting device of this case collects and releases the fabric through the receiving roller and the discharging roller, which can keep the fabric straight and prevent the fabric from being creased during cutting, which affects the appearance. Moreover, the receiving roller and the conveyor belt unit rotate synchronously. After the fabric is cut, the waste and the finished fabric are transported synchronously, which is convenient for separating and collecting the waste and the finished fabric. Moreover, since the receiving roller and the conveyor belt unit do not move relative to each other, there is no friction between the fabric and the conveyor belt unit, and the fabric will not be damaged.

Secondly, after the receiving roller and the unwinding roller straighten the fabric, the pressing unit presses the edge of the fabric, further preventing the fabric from wrinkling when the cutting unit is cutting. Moreover, after cutting, the pressing unit is pressed by rollers, so the receiving roller can rotate to collect the fabric without lifting the pressing unit, thus reducing the workload of the staff and improving efficiency.

The pressing unit 5 includes a cross bar 51, a roller 52 and an elastic adjustment module 53 for the roller 52 to press the cloth; the cross bar 51 is fixed on the fixing frame 1; the elastic adjustment module 53 is fixed on the free end of the cross bar 51; the roller 52 is fixed on the free end of the elastic adjustment module 53.

In this embodiment, the unwinding roller is the rotating shaft attached to the finished cloth roll provided by the supplier. It only needs to place the rotating shaft on the fixed frame 1. No power is required. The cloth is pulled by the receiving roller 3 to rotate out the cloth. After use, it only needs to replace the new cloth roll. The conveyor belt unit 2 is a conveyor belt used on the market. It is a structure that drives the object to move by rotating through a plastic belt or a felt belt. The first driving module 7 is a motor, but other power sources such as a rotary cylinder and a hydraulic cylinder can also be selected according to actual conditions. The specific working process of the cloth cutting device is as follows: the staff pulls the cloth on the unwinding roller out along the conveyor belt unit 2, and presses the roller 52 of the pressing unit 5 on the cloth, so that the cloth is close to the conveyor belt unit 2, and then fixes the free end of the cloth on the receiving roller 3. The cutting unit 6 cuts the cloth according to the required cloth shape. After the cutting is completed, the first driving module 7 drives the conveyor belt unit 2 and the receiving roller 3 to rotate at the same time, and the finished fabric and the waste material move forward at the same speed. The waste material is collected on the receiving roller 3, and the finished fabric is transported to the finished product collection area along the conveyor belt unit 2. After the receiving roller 3 collects the waste material, the conveyor belt unit 2 is filled with uncut fabric for the next cutting and collection.

The conveyor belt unit 2 and the receiving roller 3 rotate synchronously, so that the waste material and the finished fabric will not move relative to each other, thus preventing the finished fabric from getting stuck on the conveyor belt module due to its small area, thus affecting subsequent processing. Secondly, the conveyor belt unit 2 and the receiving roller 3 rotate synchronously, and when the receiving roller 3 is winding up the waste material, the waste material and the finished fabric will not move relative to the conveyor belt unit 2, thus preventing the conveyor belt unit 2 and the finished fabric from moving relative to each other and causing damage to the finished fabric.

Preferably, the receiving roller 3 is connected to the conveyor belt unit 2 via a chain, a belt or a gear to achieve synchronous rotation of the conveyor belt unit 2 and the receiving roller 3 .

In this embodiment, the receiving roller 3 is connected to the conveyor belt unit 2 via a chain. However, when in use, the transmission ratio between the first driving module 7 and the receiving roller 3 and the conveyor belt unit 2 should be equal, so that the conveyor belt unit 2 and the receiving roller 3 can rotate synchronously.

The cylinder pushes the cloth cutting wheel to move downward and press against the cloth. According to the required cloth shape, the horizontal driving module 63 and the vertical driving module 64 drive the cloth cutting wheel to cut along the set path. After cutting is completed, the cylinder drives the cloth cutting wheel to return to the initial state.

Preferably, the elastic adjustment module 53 includes a fixed block 531, a push rod 532 and a spring 533; the push rod 532 is slidably connected to the fixed block 531; a limit block is provided at the end of the push rod 532 for limiting the push rod 532 from detaching from the fixed block 531; the spring 533 is sleeved on the push rod 532 and is located inside the fixed block 531; the fixed block 531 is fixedly connected to the cross bar 51; the free end of the push rod 532 is fixedly connected to the roller 52.

In this embodiment, when the cloth is placed on the conveyor belt unit 2 and the roller 52 is pressed against the cloth, the spring 533 is deformed to generate elastic force, thereby being able to adapt to the thickness of the cloth without adjusting the pressing unit 5 according to the thickness of the cloth.

Preferably, the crossbar 51 is a telescopic rod. Through the adjustable length of the telescopic rod, the use of fabrics of different widths can be satisfied.

Preferably, it also includes a finished product collection frame 8; the finished product collection frame 8 is placed on one side of the fixed frame 1 close to the receiving roller 3; the conveyor belt unit 2 conveys the finished fabric to the finished product collection frame 8.

In this embodiment, in order to facilitate the subsequent transportation of the finished fabrics, the finished product collection frame 8 is placed below the receiving roller 3 and at the end of the conveyor belt unit 2, so that when the finished fabrics leave the conveyor belt unit 2, the finished fabrics can enter the finished product collection frame 8.

Preferably, a rotatable guide plate 9 is provided on one side of the fixed frame 1 close to the receiving roller 3 ; the guide plate 9 is used to allow the finished fabric to slide from the conveyor belt unit 2 through the guide plate 9 into the finished product collection frame 8 .

In this embodiment, in order to further enable the finished fabric to enter the finished product collection frame 8, a guide plate 9 is arranged between the conveyor belt unit 2 and the finished product collection frame 8, one end of the guide plate 9 is close to the end of the conveyor belt unit 2, and the other end of the guide plate 9 is overlapped on the upper edge of the finished product collection frame 8, so that the finished fabric can pass through the conveyor belt unit 2 and then enter the finished product collection frame 8 through the guide plate 9, thereby preventing the fabric from falling outside the finished product collection frame 8 and making the finished fabric dirty or damaged.
