[0020] The embodiments of the application are further described in detail below with reference to the accompanying drawings.

[0021] Figures 1 to 5 is a schematic diagram of the structure of the application.

[0022] The reference signs in the drawings are as follows: first support body 1, second support body 2, second motor 21, second pressure roller body 22, first air cylinder 23, sliding seat 24, first pressure roller body 3, first motor 31, air blowing pipe 4, conveying wheel 5, feeding motor 52, roller 53, moving seat 54, second air cylinder 55, sensing sheet 56, joint sensing device 57, photoelectric sensor 58, second pressure roller body 6, auxiliary wheel 7, groove 71, folding material conveying belt 8, folding material driving motor 81, folding material synchronous wheel 82, winding part 9a, folding part 9b, edge position 9c.

[0023] The automatic folding equipment for sewing material of the application comprises a first support body 1 and a second support body 2 for supporting the inner side of the cloth sewn in a circle. The cloth is sleeved on the first support body 1 and the second support body 2.

[0024] A first pressing roller body 3 for clamping the looped fabric is arranged outside the first support body 1, and a first motor 31 for driving the looped fabric to rotate around the first support body 1 and the second support body 2 is connected to the first pressing roller body 3. The first pressing roller body 3 and the first support body 1 clamp the fabric, and when the first motor 31 drives the first pressing roller body 3 to rotate, the fabric can rotate around the first support body 1 and the second support body 2.

[0025] A second pressing roller body 22 is arranged outside the second support body 2, and the second pressing roller body 22 is mounted on a sliding seat 24 and the position of the second pressing roller body 22 is controlled by a first air cylinder 23. When the second pressing roller body 22 is close to the second support body 2, the two clamp the fabric and can drive the fabric to rotate, and when the second pressing roller body 22 is away from the second support body 2, it is convenient for feeding operation.

[0026] A plurality of air blowing pipes 4 for folding the fabric are arranged inside the looped fabric, and a fabric folding conveying belt 8 is arranged for conveying the folded part 9b of the fabric inward. The air blowing pipes 4 are arranged in multiple numbers and the air blowing pipes are arranged in distribution. The folded part 9b of the fabric falls in front of the first support body 1 and the second support body 2, and after being blown by the air blowing pipes 4, the folded part 9b is blown to the bottom surface of the winding part 9a, and then is conveyed by the fabric folding conveying belt 8; in the case of simultaneous rotation of the fabric, the folded part 9b and the winding part 9a of the whole fabric can be folded together.

[0027] The first support body 1 is an arc-shaped plate body for supporting the inner side of the fabric, and the air blowing pipes 4 and the fabric folding conveying belt 8 are arranged inside the arc-shaped plate body. The arc-shaped plate body has a smooth surface, and the fabric can rotate along the wall surface of the arc-shaped plate body, the air blowing pipes 4 blow the folded part 9b to the inner bottom surface of the arc-shaped plate body, and then the folded part 9b is flattened by the fabric folding conveying belt 8.

[0028] As shown in Figure 1 The fabric folding conveying belt 8 is arranged longitudinally, and the conveying direction is perpendicular to the rotation direction of the fabric. The fabric folding conveying belt 8 is rotatably mounted on a fabric folding synchronous wheel 82, and the fabric folding synchronous wheel 82 is connected to a fabric folding driving motor 81.

[0029] A second pressing roller body 6 for clamping the looped fabric is arranged outside the second support body 2, and the second support body 2 or the second pressing roller body 6 can rotate independently.

[0030] The fabric automatic folding equipment is provided with a second motor 21 for driving the second support body 2 or the second pressing roller body 6 to rotate. In this embodiment, the second motor 21 is connected to the second support body 2 through a synchronous belt, and drives the second support body 2 to rotate, and cooperates with the first pressing roller body 3 to make the fabric rotate around the first support body 1 and the second support body 2.

[0031] As shown in Figure 5As shown, the outer side of the arc-shaped plate body is provided with a conveying wheel 5 for driving the fabric to move forward and backward, and a feeding motor 52 for driving the conveying wheel 5 to rotate.

[0032] The automatic fabric folding equipment is provided with a photoelectric sensor 58 for detecting the position of the fabric, and a driving module for controlling the working state of the feeding motor 52. The edge position 9c of the fabric winding part 9a is sensed in real time, when the edge deviates to the rear part, the feeding motor 52 drives the conveying wheel 5 to rotate and moves the fabric winding part 9a to the front; when the edge deviates to the front part, the feeding motor 52 drives the conveying wheel 5 to rotate and moves the fabric winding part 9a to the rear. Through the control of the driving module, the fabric winding part 9a can be folded, i.e. the width of the fabric winding part 9a is controlled to be equal to the width of the folding part 9b, so as to meet the folding process requirements.

[0033] The conveying wheel 5 is provided with a rotatable roller 53 at the edge of the wheel disc, and the wheel surface of the roller 53 is perpendicular to the wheel surface of the conveying wheel 5. When the conveying wheel 5 drives the fabric to move forward and backward, the roller 53 can conform to the rotating movement of the fabric.

[0034] In order to improve the fabric moving effect of the conveying wheel 5, a rotatable auxiliary wheel 7 is installed on the outer wall of the arc-shaped plate body, and the wheel disc of the auxiliary wheel 7 is provided with spaced grooves 71, and the roller 53 can be clamped into the grooves 71, so as to increase the contact area of the fabric and the friction force during the fabric moving.

[0035] The outer side of the arc-shaped plate body is also provided with a sensing sheet 56 connected with a seam sensor 57, which can sense the looped seam part of the fabric. The sensing sheet 56, the seam sensor 57, the feeding motor 52 and the conveying wheel 5 are installed on a moving seat 54, and the moving seat 54 can move left and right under the control of a second air cylinder 55. When the second air cylinder 55 controls the moving seat 54 to move away from the first support body 1, the feeding is facilitated. The seam sensor 57 can also control the moving seat 54 to move away from the first support body 1 when the seam is sensed, so that the conveying wheel 5 and the roller 53 avoid the seam part. The seam sensor 57 can also be used to automatically identify the number of loops of the rotating fabric, and automatically stop after the complete folding of the fabric.

[0036] The best embodiment of the present application has been described, and various changes or modifications made by those skilled in the art will not deviate from the scope of the present application.
