[0002] A sewing belt is a raw material for sewing products, and plays roles such as ornament hanging, carrying or strength increasing in sewing products.

[0003] Currently, during the process of sewing a sewing belt with other raw materials, generally, the sewing belt is manually conveyed to a sewing machine, or conveyed through the cooperation of a production line and rollers.

[0004] However, the above-mentioned manual conveying method has the disadvantages of low conveying efficiency and high labor intensity.

[0005] Meanwhile, the above-mentioned conveying method through the cooperation of a production line and rollers has the problems of uneven conveying (when the sewing belt cannot be straightened, it is easy to deform during conveying), easy wear (when the roller pulling force is too large and the sewing belt contacts too many groups of rollers during conveying, it is easy to cause frictional wear), and it is very difficult to adjust the roller pulling force to a better state, which are the disadvantages of roller conveying. Summary of the Invention

[0006] The purpose of the utility model is to overcome the above-mentioned defects in the prior art, and provide a sewing conveying and feeding mechanism, which has high conveying efficiency, ensures uniform conveying and is not easy to wear during the automatic conveying of the sewing belt, and effectively reduces the manual labor intensity.

[0007] To achieve the above purpose, the utility model provides a sewing conveying and feeding mechanism, which includes a frame, and also includes a linear conveying module installed on the frame, a first lifting drive module installed on the linear conveying module, and at least one sewing belt clamping assembly installed on the first lifting drive module. The sewing belt clamping assembly includes a position drive cylinder installed on the first lifting drive module, a third connecting plate installed on the position drive cylinder, and a clamping drive cylinder installed on the third connecting plate. A first clamping arm is installed on the clamping drive cylinder, and a second clamping arm is oppositely arranged relative to the first clamping arm.

[0008] Preferably, the linear conveying module drives the first lifting drive module to reciprocate linearly, the first lifting drive module drives the sewing belt clamping assembly to reciprocate up and down, the position drive cylinder drives the third connecting plate to reciprocate close to or away from the sewing belt, and the clamping drive cylinder drives the first clamping arm to reciprocate close to or away from the second clamping arm.

[0009] Preferably, the linear conveying module includes a rotary drive motor, a synchronous pulley and belt assembly drivingly connected to the rotary drive motor, a slide rail and slider assembly installed on one side of the synchronous pulley and belt assembly, and a first connecting plate drivingly connected to the synchronous pulley and belt assembly and slidably connected to the slide rail and slider assembly. The first lifting drive module is installed on the first connecting plate.

[0030] Among them, the linear conveying module 2 drives the first lifting drive module 3 to reciprocate linear motion, the first lifting drive module 3 drives the sewing tape clamping assembly 4 to reciprocate and lift, the position driving cylinder 41 drives the third connecting plate 42 to reciprocate close to or away from the sewing tape, and the clamping driving cylinder 43 drives the first clamping arm 44 to reciprocate close to or away from the second clamping arm 45.

[0031] The linear conveying module 2 includes a rotary drive motor 21, a synchronous wheel and synchronous belt assembly 22 which is transmission-connected to the rotary drive motor 21, a slide rail and slider assembly 23 installed on one side of the synchronous wheel and synchronous belt assembly 22, and a first connecting plate 24 which is transmission-connected to the synchronous wheel and synchronous belt assembly 22 and slidingly connected to the slide rail and slider assembly 23.

[0034] The first clamping arm 44 and the second clamping arm 45 are both pressing pieces.

[0035] An example of the sewing and conveying material mechanism of the present utility model further includes an upper pressing component 5 installed on one side of the sewing belt clamping component 4 and cooperating with the sewing belt clamping component 4.

[0036] The upper pressing component 5 includes a second lifting drive cylinder 51, a fixed shaft rod 52, a swing rod 53, and an upper pressing cross bar 54. The second lifting drive cylinder 51 and the fixed shaft rod 52 are respectively installed on the machine frame 1.

The upper pressing cross bar 54 is installed at the other end of the swing rod 53.

[0037] The function of the upper pressing component 5 is that when the linear conveying module 2 drives the sewing belt on the sewing belt clamping component 4, the upper pressing cross bar 54 of the upper pressing component 5 presses on the top of the sewing belt, so that the sewing belt is further straightened.

[0038] The above-mentioned upper pressing component 5 further includes a cam 55 or a roller or a bearing installed on the second lifting drive cylinder 51 and abutted against one side wall of the swing rod 53. Among them, the cam 55 or the roller or the bearing abuts against the upward side wall of the swing rod 53.

[0040] An example of the sewing and conveying material mechanism of the present utility model, its specific operation principle is as follows:

[0041] S1: Manually or directly load the sewing belt through a sewing belt winding device or a sewing belt loading table (the sewing belt loading table is a prior art, that is, a table surface with a set of conveying rollers) onto the sewing belt clamping component 4;

[0042] S2: The position drive cylinder 41 of the sewing belt clamping component 4 drives the clamping drive cylinder 43 on the third connecting plate 42 to approach the sewing belt;

[0043] S3: The clamping drive cylinder 43 drives the first clamping arm 44 to approach the second clamping arm 45, so that the sewing belt is clamped between the first clamping arm 44 and the second clamping arm 45;

[0044] S4: The linear conveying module 2 drives the first lifting drive module 3 to move linearly to the sewing belt assembly or sewing station, thereby driving the sewing belt clamping assembly 4 to move linearly to the sewing belt assembly or sewing station. Among them, the rotary drive motor 21 rotates, driving the synchronous belt on the synchronous pulley synchronous belt assembly 22 to rotate, thereby driving the first connecting plate 24 to move linearly along one side of the synchronous belt. At this time, the slide rail slider assembly 23 plays a role in assisting the smooth movement.

[0045] S5: During the process of the sewing belt clamping assembly 4 moving linearly to the sewing belt assembly or sewing station, the upper pressing assembly 5 behind the sewing belt clamping assembly 4 starts to act. Among them, the second lifting drive cylinder 51 of the upper pressing assembly 5 drives upward, causing the end of the swing rod 53 connected to the second lifting drive cylinder 51 to rotate upward, and the other end of the swing rod 53 installed with the upper pressing cross bar 54 to rotate downward, so that the upper pressing cross bar 54 presses downward on the top of the sewing belt, thus straightening the sewing belt and further improving the uniform conveying of the sewing belt.

[0046] S6: When reaching the designated sewing belt assembly or sewing station, the first lifting drive cylinder 31 of the first lifting drive module 3 drives the sewing belt clamping assembly 4 upward or downward to reach the designated sewing belt assembly or sewing station.

[0047] S7: At this time, the sewing belt conveying mechanism is completed, and the sewing belt clamping assembly 4 resets and moves away from the sewing belt. Instead, the positioning assembly on the sewing belt assembly or sewing station fixes and positions the sewing belt so that the sewing belt completes the combination or sewing work of the next process.

[0048] A sewing and conveying material mechanism according to an embodiment of the present invention can convey evenly, is not easily worn, has high conveying efficiency, and low manual labor intensity during the automatic conveying process of the sewing belt.
