The belt loop feeding mechanism shown in fig. 1 is used for bending and conveying belt loops to a machine head 107 of a sewing device, and comprises a clamping assembly, the clamping assembly is provided with two clamping jaws 101 which are arranged at intervals, the two clamping jaws 101 are both connected with a clamping cylinder, wherein at least one clamping jaw 101 can rotate to bend the belt loops, namely one clamping jaw 101 is connected with a rotating cylinder, the specific structure of the belt loop feeding mechanism can be that a sleeve used for accommodating the clamping cylinder is arranged at the output end of the rotating cylinder, the rotating cylinder drives the clamping cylinder and the clamping jaw 101 to rotate for a certain angle, and the clamping cylinder drives the clamping jaw 101 to clamp the end parts or the middle section of the belt loops; the clamping assembly is connected with a linear driving mechanism 102, the linear driving mechanism 102 can be a common linear sliding table in the market or a telescopic cylinder, and the linear driving mechanism 102 is horizontally arranged and can drive the clamping assembly to be close to or far away from the machine head 107 along the horizontal direction, so that the bent belt loops are sent to the machine head 107 for sewing operation; the belt loop feeding mechanism further comprises a first blocking structure 103 and a second blocking structure 104, the first blocking structure 103 is arranged between the two clamping jaws 101, one clamping jaw 101 grasps the end portion of the belt loop, the other clamping jaw 101 clamps the middle section of the belt loop and rotates through a rotating air cylinder, and then the belt loop is driven to turn over along the clamping point of the middle section, at the moment, the middle section is lapped on the first blocking structure 103, and the phenomenon that the middle section or the other end portion of the belt loop covers the end portion to cause sewing quality accidents is avoided; the second blocking structure 104 is arranged at the machine head 107, the first blocking structure 103 feeds the belt loop into the machine head 107 along with the clamping assembly and resets, at the moment, the end part and the bending point of the belt loop are fixed through the presser foot 108, the second blocking structure 104 blocks the middle section of the belt loop from being fed into the machine head 107, and the presser foot 108 is prevented from pressing the middle section to the end part covering the belt loop.

In some embodiments, the front end of the clamping jaw 101 is pointed, so that the clamping jaw 101 moves horizontally with the linear driving mechanism 102 to approach and pass through the upper and lower sides of the belt loop, and the pointed design can avoid the clamping jaw 101 from being plugged on the belt loop to cause accidents.

In some embodiments, the first blocking structure 103 is in the form of a plate and is disposed above the jaws 101, and further, one of the jaws 101 holds the middle section of the belt loop and forces the middle section to bend from top to bottom relative to the end of the belt loop, where the middle section overlaps the first blocking structure 103 to prevent the belt loop from folding up and down along its bending point.

In some embodiments, referring to fig. 2, the second blocking structure 104 is in a strip shape and is bent with a recess 105, the second blocking structure 104 can block the middle section of the belt loop in the recess 105, that is, the middle section overlapping the first blocking structure 103 is fed into the head 107 along with the clamping jaw 101 and abuts against the second blocking structure 104, the second blocking structure 104 restricts the middle section from being fed into the head 107 along with the clamping jaw 101, and then the presser foot 108 at the head 107 presses the end of the belt loop and the bending point, which is to be noted that the two ends of the belt loop do not overlap or the middle section of the belt loop does not overlap with the end thereof; the clamping assembly drives the clamping jaw 101 to release the belt loop, and the linear driving mechanism 102 drives the clamping jaw 101 to be far away from the machine head 107, so that the feeding operation is realized.

In some embodiments, the first blocking structure is located below the second blocking structure 104, i.e. the first blocking structure 103 is offset from the second blocking structure 104, and more particularly, the second blocking structure 104 is located in the moving path of the clamping assembly and can be clear of the first blocking structure 103, avoiding the first blocking structure 103 from interfering with the second blocking structure 104 as the clamping jaw 101 approaches the handpiece 107.

The sewing device comprises the loop feeding mechanism of the embodiment, and further comprises a working platform 106 and a machine head 107, wherein the machine head 107 can adopt the model of the conventional sewing device on the market, the machine head 107 is arranged above the moving platform, the loop feeding mechanism can move the loops between the machine head 107 and the working platform 106, the machine head 107 is provided with two pressure feet 108, and the two pressure feet 108 are respectively pressed on the end parts and the bending points of the loops in the embodiment; specifically, the presser foot 108 is connected to a power mechanism, which may be a vertically downward telescopic cylinder, capable of driving the presser foot 108 to move downward and press the loops and the clothes onto the working platform 106.

In some embodiments, referring to fig. 2, the presser foot 108 is provided with an avoiding groove cooperating with the clamping jaw 101, so as to prevent the presser foot 108 from moving downwards and pressing against the clamping jaw 101, so that the clamping jaw 101 is difficult to remove from the head 107, the cross-sectional dimension of the avoiding groove is larger than that of the two clamping jaws 101, that is, the two clamping jaws 101 respectively clamp one end and a middle section of the belt loop and feed the belt loop under the head 107, the two presser feet 108 move downwards and press the belt loop on the working platform 106, and the clamping jaw 101 is located in the avoiding groove and can also move freely, so that the clamping jaw 101 can be conveniently withdrawn from the head 107.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
