The two groups cooperate to align the tail end of the second cloth with the head end of the first cloth. The specific operation of the cloth handling assembly is as follows: initially, the first cylinder is in an open state. When a detection switch detects the cloth, the first cylinder rotates and returns to its original position, so that the first cloth handling clamp and the second cloth handling clamp reach a pre-clamping state. The three-axis slide drives the cloth handling clamp to move toward both ends of the cloth. When the outer detection switch cannot detect the cloth and the inner detection switch can detect the cloth, the three-axis slide stops moving toward both ends of the cloth, and the output end of the first cylinder returns to allow the cloth handling clamp to clamp the cloth, and drives the cloth to a set position.

[0054] Conducting rollers are respectively arranged between the cloth outlet end 2 and the seam assembly 4 and between the material placement end 3 and the seam assembly 4 .

[0055] A cloth receiving method of a cloth receiving machine comprises the following steps:

[0056] Step 1: The cloth sorting assembly 5 near the cloth outlet 2 clamps the edge of the second cloth 23, drives the cloth sorting clamp 51 to both sides of the second cloth 23 through the three-axis slide 53, and attaches the second cloth 23 to the attaching plate 41;

[0057] Step 2: The loading component 9 transports the first cloth 31 to the loading end 3;

[0058] Step 3: The material placement end 3 drives the first fabric 31 to rotate, and the airflow passes through the blowing slot 86 to blow the edge of the first fabric 31 into the cloth clamping nozzle 84;

[0059] Step 4: The clamping assembly 8 pulls down the edge of the first fabric 31 to the fabric handling assembly 5 below it. When the detection switch 52 detects the first fabric 31, the fabric handling clamp 51 clamps the first fabric 31, and the clamping mouth 84 releases the first fabric 31. The fabric handling clamp 51 is driven to both sides of the first fabric 31 through the three-axis slide 53, and the first fabric 31 is aligned and attached to the second fabric 23.

[0060] Step 5: The pressing assembly 6 presses the second fabric 23 and the first fabric 31, and the fabric handling clamp 51 is released and returned;

[0061] Step 6: The seaming assembly 4 slides along the length direction of the mounting plate 41 , the cloth leveling assembly 7 flattens the edges of the second cloth 23 and the first cloth 31 , and the seaming machine 42 sews the edges of the second cloth 23 and the first cloth 31 after the display.

[0062] Both ends of the frame 1 are provided with mounting grooves 14, and both ends of the crossbeam 43 are installed in the mounting grooves 14. Between steps 1 to 5, the seaming machine 42 and the cloth-distributing assembly 7 on the seaming assembly 4 are both located in the mounting grooves 14, thereby facilitating the sliding of the cloth-distributing assembly 5.

[0063] In step 4, the cloth handling clamp 51 is driven to both sides of the first cloth 31 by the three-axis slide 53, specifically when the detection switch 52 at the outer end cannot detect the first cloth 31, and the detection switch 52 at the inner end can detect the first cloth 31.

[0064] The basic working principle of an automatic cloth splicing machine is as follows: a seam assembly 4 slides along the length direction of a material pasting plate 41, and the cloth leveling assembly 7 slides together with the seam assembly 4 and displays the tail end of the second cloth 23 and the head end of the first cloth 31 that are bonded together, so that the tail end of the second cloth 23 and the head end of the first cloth 31 can smoothly enter the seam area of ​​a seam splicing machine 42, and the seam splicing machine 42 sews the edges of the displayed second cloth 23 and the first cloth 31 in sequence along the sliding direction of the seam assembly 4, thereby solving the problem that the head and tail ends of the rolled cloth are curled up, making it difficult for the head and tail ends of the two rolled cloths to enter the seam area of ​​the seam splicing machine 42, and improving the cloth splicing efficiency and cloth splicing quality.
