[0043] The first cloth 31 rotates under the drive of the material placement end 3, and the air flow entering the blowing groove 86 will blow the head end of the first cloth 31 into the cloth clamping nozzle 84. When the induction switch 85 on the lower clamping nozzle 842 senses the first cloth 31, the pushing cylinder 87 pushes the lower clamping nozzle 842 upward, so that the lower clamping nozzle 842 and the upper clamping nozzle 841 are closed and clamp the end edge of the first cloth 31. The pushing cylinder 87 drives the support arm 83 to rotate downward and drives the cloth clamping nozzle 84 to the set position. The set position in the present invention is the cloth sorting component 5.

[0044] An automatic cloth-joining machine comprises a frame 1, a cloth outlet 2 for guiding a second cloth 23 and a material placement end 3 for placing a first cloth 31, and further comprises a seaming assembly 4, a cloth-handling assembly 5 and a pressing assembly 6 arranged between the frame 1, wherein the seaming assembly 4 comprises a fabric-attaching plate 41 and a seaming machine 42 that can slide in the length direction of the fabric-attaching plate 41, wherein the seaming machine 42 is used to sew the tail end of the second cloth 23 to the head end of the first cloth 31, wherein the cloth-handling assembly 5 comprises two groups, wherein one group of the cloth-handling assembly 5 is used to clamp the second cloth 23 and pull the second cloth 23 to the attaching plate 41. The bonding plate 41 is combined, and another group of cloth-sorting components 5 is used to clamp the first cloth 31 and align and bond the first cloth 31 with the second cloth 23. The pressing component 6 presses the second cloth 23 and the first cloth 31 against the bonding plate 41. One side of the seaming machine 42 is provided with a cloth-leveling component 7 for flattening the edges of the second cloth 23 and the first cloth 31.

A reduction motor for driving the support rollers 32 to move is arranged in the frame 1. The auxiliary roller 33 on the right side can be replaced by a baffle.

[0049] The clamping assembly 6 includes a clamping cylinder 61 disposed at the lower end of the cross bar 81 , guide rods 62 disposed at both sides of the clamping cylinder 61 , and a pressure strip 63 connecting the output end of the clamping cylinder 61 and the guide rods 62 .

[0050] A conveyor belt 11 is provided at the lower end of the seam assembly 4, and the conveyor belt 11 is used to transport a roller 12 falling from the material loading end 3. A channel 13 is provided on one side of the frame 1, and the roller 12 is used to wind the first cloth 31. When the first cloth 31 is wound, the roller 12 falls from the material loading end 3, and is driven to the conveyor belt 11 by the cloth sorting assembly 5. The conveyor belt 11 transports the roller 12 out of the channel 13, and then replaces manual labor to take the roller 12 out of the material loading end 3, which not only improves efficiency but also avoids the safety hazards of manual material taking.

[0051] The cloth outlet end 2 includes a cloth guide frame 21 and a sway assembly 22 for driving the cloth guide frame 21 to perform sway motion. The cloth guide frame 21 includes a swing arm 211, an active roller 212 arranged on the swing arm 211, and a plurality of passive rollers 213 arranged parallel to the active roller 212.

[0052] The automatic cloth receiving machine also includes a loading assembly 9 for loading the first cloth 31, the loading assembly 9 includes a plurality of loading rollers 91 arranged at intervals, a lifting machine 92 for lifting the first cloth 31, and a guide frame 93 for guiding the first cloth 31 to the material placement end 3. The loading assembly 9 is independent of the frame 1, and the distance between the loading assembly 9 and the frame 1 can be adjusted.

[0053] 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 .

[0054] A cloth receiving method of an automatic cloth receiving machine comprises the following steps:

[0055] 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 multi-axis slide 53, and attaches the second cloth 23 to the attaching plate 41;

[0056] Step 2: The loading component 9 transports the first cloth 31 to the loading end 3;

[0057] 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;

[0058] 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 multi-axis slide 53, and the first fabric 31 is aligned and attached to the second fabric 23.

[0059] 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;

[0060] 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.

[0061] 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.

[0062] In step 4, the cloth handling clamps 51 are driven to both sides of the first cloth 31 by the multi-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.

[0063] 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.

[0064] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
