Description

Technical Field

[0001] The utility model relates to a seaming device, in particular to a feeding mechanism used for looping and sewing a webbing. Background Art

[0002] The same applicant applied for a feeding mechanism for a double-station automatic rubber band splicing machine with publication number CN219667526U on April 17, 2023. A horizontal conveying mechanism that can slide left and right is installed on the front side of the machine, and a vertical conveying mechanism that can be extended up and down is installed on the horizontal conveying mechanism. A longitudinal conveying mechanism that can slide forward and backward is installed on the vertical conveying mechanism. A slidable inner sliding clamp is symmetrically arranged in the middle of the longitudinal conveying mechanism, and outer sliding clamps corresponding to the inner sliding clamps are symmetrically arranged on both sides of the longitudinal conveying mechanism.

[0003] The same applicant applied for a patent document on April 7, 2022, with publication number CN217104283U, for a fully automatic elastic band sewing device. The long elastic band is processed by an ultrasonic vibration head and a cutting and welding knife to form an elastic band ring with low welding strength at the connection. At this time, it is clamped by an inner sliding clamp and an outer sliding clamp and sent to a sewing machine for sewing. The applicant found that this product is only suitable for webbing containing hot melt wire and has a small scope of application. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a feeding mechanism for looping and sewing a webbing.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A feeding mechanism for webbing loop sewing comprises a transverse conveying mechanism installed on a machine platform, a vertical conveying mechanism which can be extended and retracted up and down is installed on the transverse conveying mechanism, a longitudinal conveying mechanism which can slide forward and backward is installed on the vertical conveying mechanism, a first rotating mechanism and a second rotating mechanism which can rotate 90 degrees are fixedly installed on the longitudinal conveying mechanism, and both the first rotating mechanism and the second rotating mechanism are installed with a clamp controlled by a driving mechanism.

[0007] The first rotating mechanism and the second rotating mechanism are arranged in a lateral direction and have the same height.

[0008] The first rotating mechanism and the second rotating mechanism rotate in opposite directions.

[0009] A slide rail is installed on the longitudinal conveying mechanism, and one of the first rotating mechanism or the second rotating mechanism is slidably installed on the slide rail.

[0010] A slide rail is installed on the longitudinal conveying mechanism, and the first rotating mechanism and the second rotating mechanism are both slidably installed on the slide rail.

[0011] The longitudinal conveying mechanism is provided with an adjusting nut for adjusting the distance between the first rotating mechanism and the second rotating mechanism.

[0012] The clamp is composed of a dynamic clamping block and a static clamping block. The static clamping block is fixedly mounted on the housing of the driving mechanism, and the dynamic clamping block is fixedly mounted on the telescopic shaft of the driving mechanism.

[0013] The beneficial effect of the utility model is that the first rotating mechanism and the second rotating mechanism which can rotate 90° are fixedly installed on the longitudinal transmission mechanism, and the first rotating mechanism and the second rotating mechanism are both installed with clamps controlled by the driving mechanism. After the two ends of the ribbon are clamped by the clamps, the first rotating mechanism and the second rotating mechanism are rotated 90°, so that the two ends of the ribbon are horizontal and abut against each other, and are sent to the sewing machine for sewing. The utility model can be applicable to more different types of ribbons and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0018] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0019] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0020] Reference Figures 1 to 2A feeding mechanism for looping and sewing a webbing comprises a transverse conveying mechanism 1 mounted on a machine platform, a vertical conveying mechanism 2 which can be extended and retracted up and down is mounted on the transverse conveying mechanism 1, a longitudinal conveying mechanism 3 which can slide forward and backward is mounted on the vertical conveying mechanism 2, a first rotating mechanism 4 and a second rotating mechanism 5 which can rotate 90° are fixedly mounted on the longitudinal conveying mechanism 3, the first rotating mechanism 4 and the second rotating mechanism 5 are both mounted with a clamp 9 controlled by a driving mechanism 6, after the two ends of the webbing are clamped by the clamp, the first rotating mechanism and the second rotating mechanism are rotated 90°, so that the two ends of the webbing are horizontal and abut against each other, and are sent to the sewing machine for sewing, which can be applicable to more different types of webbings and has a wide range of applications.

[0021] The first rotating mechanism 4 and the second rotating mechanism 5 are arranged in the lateral direction and have the same height.

[0022] The first rotating mechanism 4 and the second rotating mechanism 5 rotate in opposite directions. Figure 1 As shown in the figure), the first rotating mechanism 4 is located on the left side, and its rotation direction is clockwise, and the second rotating mechanism 5 is located on the right side, and its rotation direction is counterclockwise.

[0023] Embodiment 1: A slide rail 7 is installed on the longitudinal conveying mechanism 3 , and one of the first rotating mechanism 4 or the second rotating mechanism 5 is slidably installed on the slide rail 7 .

[0024] Embodiment 2: A slide rail 7 is installed on the longitudinal conveying mechanism 3 , and the first rotating mechanism 4 and the second rotating mechanism 5 are both slidably installed on the slide rail 7 .

[0025] The longitudinal transmission mechanism 3 is provided with an adjusting nut 8 for adjusting the distance between the first rotating mechanism 4 and the second rotating mechanism 5. By adjusting the distance between the first rotating mechanism 4 and the second rotating mechanism 5, the positional relationship between the two ends of the webbing after the webbing is rotated 90° can be adjusted to be exactly in contact with each other or to overlap with each other, and the overlapping part can also be adjusted.

[0026] The clamp 9 is composed of a dynamic clamping block 71 and a static clamping block 72 . The static clamping block 72 is fixedly mounted on the housing of the driving mechanism 6 , and the dynamic clamping block 71 is fixedly mounted on the telescopic shaft of the driving mechanism 6 .

[0027] A separation portion 10 is installed on the longitudinal conveying mechanism 3 in the middle of the two clamps 9. The front end of the separation portion 10 is a pointed structure, which is used to be inserted between the two ends of the ribbon to separate it, thereby avoiding the problem of curling of the ribbon itself (during weaving, the internal stress generated by the warp and weft lines themselves causes the ribbon to curl, which is a common phenomenon in the industry), thereby affecting the clamping of the clamp 9.

[0028] This product needs to cooperate with a structure for cutting the webbing in a fully automatic elastic band sewing device with publication number CN217104283U. Before cutting the webbing, the clamp 9 clamps the two ends of the webbing and then performs the cutting operation.
