[0031] Reference Figure 1The trouser loop feeding mechanism shown is used to bend the trouser loop and convey it to the head 107 of the sewing device, which includes a clamping assembly, the clamping assembly has two clamping jaws 101 arranged at intervals, the two clamping jaws 101 are connected to a clamping cylinder, wherein at least one clamping jaw 101 can rotate to bend the trouser loop, that is, one of the clamping jaws 101 is connected to a rotating drive member, the rotating drive member can be a conventional rotating cylinder, and its specific structure can be that a device for accommodating the clamping cylinder is provided at the output end of the rotating drive member The sleeve rotates the driving member to drive the clamping cylinder and the clamping claw 101 to rotate a certain angle, and the clamping cylinder drives the clamping claw 101 to clamp the end or the middle section of the trouser loop; the clamping assembly is connected to a linear drive mechanism 102, which can be a commonly used linear slide or a telescopic cylinder on the market and the linear drive mechanism 102 is horizontally arranged, which can drive the clamping assembly to approach or move away from the machine head 107 in the horizontal direction, and then send the bent trouser loop into the machine head 107 for sewing operation. The trouser loop feeding mechanism also includes a first blocking structure 103 and a second blocking structure 104. The first blocking structure 103 is arranged between two clamping jaws 101, wherein one clamping jaw 101 grasps the end of the trouser loop, and the other clamping jaw 101 clamps the middle section of the trouser loop and realizes self-rotation by rotating the driving member, thereby driving the trouser loop to fold along the clamping point of the middle section. At this time, the middle section is overlapped on the first blocking structure 103 to prevent the middle section or the other end of the trouser loop from covering the end, causing sewing Quality accident; the second blocking structure 104 is arranged at the machine head 107, and the axis of the first blocking structure 103 and the axis of the second blocking structure 104 are staggered and intersected in space. The first blocking structure 103 sends the trouser loop into the machine head 107 with the clamping assembly and resets it. At this time, the end and the bending point of the trouser loop are fixed by the presser foot 108, and the second blocking structure 104 blocks the middle section of the trouser loop from being sent into the machine head 107, preventing the presser foot 108 from pressing the middle section to cover the end of the trouser loop.

[0032] In some embodiments, the front end of the clamp 101 is pointed. The purpose is that the clamp 101 moves horizontally with the linear drive mechanism 102 to approach and pass through the upper and lower sides of the trouser loop. The pointed design can prevent the clamp 101 from being inserted into the trouser loop and causing accidents.

[0033] In some embodiments, the first blocking structure 103 is in the form of a sheet and is disposed above the clamping jaws 101. Furthermore, one of the clamping jaws 101 clamps the middle section of the trouser loop and drives the middle section to bend from top to bottom relative to the end of the trouser loop. At this time, the middle section is overlapped with the first blocking structure 103 to prevent the trouser loop from folding up and down along its bending point.

[0034] In some embodiments, reference Figure 2The second blocking structure 104 is strip-shaped and bent with a recess 105. The second blocking structure 104 can block the middle section of the trouser loop in the recess 105, that is, the middle section overlapped on the first blocking structure 103 is sent into the machine head 107 with the clamping jaws 101 and abuts the second blocking structure 104. The second blocking structure 104 restricts the middle section from continuing to be sent into the machine head 107 with the clamping jaws 101, and then the presser foot 108 at the machine head 107 presses the end and the bending point of the trouser loop. It should be noted that at this time, the two ends of the trouser loop do not overlap or the middle section of the trouser loop does not overlap with its end; the clamping assembly drives the clamping jaws 101 to release the trouser loop, and the linear drive mechanism 102 drives the clamping jaws 101 away from the machine head 107 to realize the feeding operation.

[0035] In some embodiments, the first blocking structure is located below the second blocking structure 104, that is, the first blocking structure 103 and the second blocking structure 104 are staggered. More specifically, the second blocking structure 104 is arranged on the moving path of the clamping assembly and can avoid the first blocking structure 103 to prevent the first blocking structure 103 from interfering with the second blocking structure 104 when the clamp 101 approaches the head 107.

[0036] The sewing equipment includes a trouser loop feeding mechanism as in the above-mentioned embodiment, and also includes a working platform 106 and a machine head 107. The machine head 107 can adopt the model of conventional sewing equipment on the market. The machine head 107 is arranged above the moving platform. The trouser loop feeding mechanism can transfer the trouser loop to between the machine head 107 and the working platform 106. A presser foot 108 is arranged on the machine head 107. In the present embodiment, there can be two presser feet 108, and the two presser feet 108 respectively press the end and the bending point of the trouser loop; specifically, the presser foot 108 is connected to a power mechanism, which can be a telescopic cylinder arranged vertically downward, which can drive the presser foot 108 to move downward and press the trouser loop and the clothes on the working platform 106.

[0037] In some embodiments, reference Figure 2 The presser foot 108 is provided with an avoidance groove cooperating with the clamping jaw 101 to prevent the presser foot 108 from moving downward and pressing the clamping jaw 101, making it difficult for the clamping jaw 101 to be moved out of the machine head 107. The cross-sectional size of the avoidance groove is larger than the cross-sectional size of the two clamping jaws 101. That is to say, the two clamping jaws 101 respectively clamp one end portion and the middle section of the trouser loop and send the trouser loop under the machine head 107. The two presser feet 108 move downward and press the trouser loop onto the working platform 106. At this time, the clamping jaw 101 is located in the avoidance groove and can also move freely, which facilitates the clamping jaw 101 to withdraw from the machine head 107.

[0038] The method for feeding trouser loops comprises the following steps:

[0039] The two clamping jaws 101 respectively clamp one end of the trouser loop and any position of the middle section of the trouser loop; specifically, the trouser loop is flattened and placed on the horizontal moving path of the clamping jaws 101, which can be flattened by hand and placed on the front end of the clamping jaws 101, so that the clamping jaws 101 can accurately clamp one end and the middle section of the trouser loop;

[0040] The clamping jaw 101 for clamping the middle section of the trouser loop rotates and drives the middle section of the trouser loop or the other end thereof to overlap the first blocking structure 103. At this time, the middle section of the trouser loop forms an angle with respect to the bending point, and the angle is usually between 45° and 90°, so as to prevent the middle section from covering the end of the trouser loop.

[0041] The linear drive mechanism 102 drives the clamping assembly to approach the head 107 of the sewing device in the horizontal direction;

[0042] The presser foot 108 presses two clamping points on the trouser loop. Specifically, the two clamping points are the ends and the bending points of the trouser loop clamped by the clamping jaws 101. During this process, the clamping jaws 101 are accommodated in the avoidance grooves on the presser foot 108, that is, the presser foot 108 only presses the trouser loop and does not interfere with the clamping jaws 101. After the presser foot 108 presses the trouser loop, the second blocking structure 104 blocks the middle section of the trouser loop to prevent the middle section from overlapping the ends of the trouser loop that the presser foot 108 presses or overlapping the presser foot 108.

[0043] The clamping jaw 101 releases the trouser loop and moves away from the machine head 107 in the horizontal direction to achieve material loading.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
