[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0029] Next, various non-limiting embodiments of the present invention will be specifically introduced. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] As Figure 1 shown, an efficient strip straight positive and reverse edge-locking machine sequentially includes a material feeding rack 1, a positive and reverse edge-locking main body, and a material receiving rack 5. The positive and reverse edge-locking main body includes a frame and a straight sewing mechanism 2 and an edge-locking mechanism 3 sequentially arranged on the frame. A variety of fabrics located on the material feeding rack 1 pass through the straight sewing mechanism 2 and the edge-locking mechanism 3 in sequence and finally reach the material receiving rack 5.

[0031] Specifically, asFigures 1 - 3 As shown in the figure, the edge-locking mechanism 3 includes a front edge-locking head 7, a reverse edge-locking head 6 movably assembled on the frame, and a first fabric pulling assembly 8 and a first synchronization assembly 27 arranged on the frame. The first fabric pulling assembly 8 is used to pull the strip to move. The moving directions of the front edge-locking head 7 and the reverse edge-locking head 6 are perpendicular to the moving direction of the strip. The front edge-locking head 7 is used to sew one side of the strip, and the reverse edge-locking head 6 is used to sew the other side of the strip, that is, the front edge-locking head 7 and the reverse edge-locking head 6 are respectively arranged on both sides of the strip. In this embodiment, both the front edge-locking head 7 and the reverse edge-locking head 6 are automatic thread trimming and automatic presser foot lifting overlock sewing machines produced by Pegasus of Japan, with the model M900.

[0032] As Figure 2 shown, the first synchronization assembly 27 includes two slide bars 11 extending in the up and down direction and arranged at intervals, and a cross bar 12 slidably assembled on the two slide bars 11. The cross bar 12 extends horizontally. The two slide bars 11 are arranged on the frame, and the strip is used to bypass from the lower side of the cross bar 12. Sliders 13 are slidably assembled on both of the two slide bars 11, and the cross bar 12 is rotatably assembled on the two sliders 13. In this embodiment, the linear sewing mechanism 2 and the edge-locking mechanism 3 are integrated into one device, which avoids frequent machine replacement, ensures the quality of the strip, and improves the efficiency. There are two travel switches arranged on the frame. One travel switch is located at the upper end position of the slide bar 11, and the other travel switch is located at the lower end position of the slide bar 11. When the slider 13 slides on the slide bar 11, it can contact the two travel switches respectively. When the slider 13 contacts the travel switch at the lower end, it will control the material receiving rack 5 to start receiving the strip. At this time, the cross bar 12 will rise under the drive of the strip. When the slider 13 contacts the travel switch at the upper end, it will control the material receiving rack 5 to stop receiving the strip. Because the edge-locking mechanism 3 is still running, the length of the strip will become longer, and the strip will no longer press up against the cross bar 12. The cross bar 12 will slide downward under the action of gravity. When the slider 13 contacts the travel switch at the lower end, the above process is repeated.

[0033] Specifically, as Figures 2 - 5As shown in the figure, two driving components 9 are provided on the frame, which are respectively used to drive the forward edge-locking head 7 and the reverse edge-locking head 6 to move. The driving component 9 includes a lead screw 20 extending in the front-rear direction and rotatably assembled on the frame, two guide rods 21 extending in the front-rear direction and provided on the frame, a mounting seat 22 threadedly connected to the lead screw 20 and slidably assembled on the guide rods 21, and a driving member 23 drivingly connected to the lead screw 20. The forward edge-locking head 7 and the reverse edge-locking head 6 are respectively fixedly assembled on the corresponding mounting seats 22. The driving member 23 drives the lead screw 20 to rotate, so that the mounting seat 22 on the lead screw 20 drives the forward edge-locking head 7 and the reverse edge-locking head 6 to move. By driving the corresponding forward edge-locking head 7 and reverse edge-locking head 6 to move through the driving component 9, the device can be applied to the production and processing of various specifications of gaskets, and the applicable range is wider. In this embodiment, the driving member 23 is a handwheel.

[0034] In other embodiments, the number of the guide rods 21 is more than three.

[0035] In other embodiments, the driving member 23 is a motor.

[0036] As Figure 5 、 Figure 6 shown, a support table 16 for supporting the gasket is slidably assembled on the two guide rods 21. A reference member 17 is movably assembled on the support table 16 in the front-rear direction. The reference member 17 is used to closely adhere to the gasket. The area between the two reference members 17 is for the gasket to pass through. The reference member 17 can make the gasket move more neatly, avoid deviation of the gasket during movement, and ensure the quality of the gasket. The reference member 17 facing the forward edge-locking head 7 is on the same side of the gasket as the reverse edge-locking head 6, and the reference member 17 facing the reverse edge-locking head 6 is on the same side of the gasket as the forward edge-locking head 7. In this embodiment, the so-called "facing" means being located on the same guide rod 21.

[0037] Specifically, a waist-shaped hole 19 extending in the front-rear direction is provided on the support table 16. The reference member 17 slides in the waist-shaped hole 19, so as to facilitate adjusting the position of the reference member 17 on the support table 16, and further adjusting the distance between the two reference members 17 to be applicable to gaskets of various specifications.

[0038] The driving component 9 is provided with a bellows cover 10 for protecting the lead screw 20. The bellows cover 10 prevents impurities from falling onto the lead screw 20 and avoids affecting the operation of the lead screw 20.

[0039] Specifically, as Figure 2 、 Figure 3As shown, a waste recycling mechanism 4 is further provided on the frame. The waste recycling mechanism 4 includes a recycling barrel 14, two recycling pipes 15 communicated with the recycling barrel 14, and a blower 18. The two recycling pipes 15 are respectively matched with the positive edge-locking head 7 and the negative edge-locking head 6 to extract the fabric impurities generated during the operation of the positive edge-locking head 7 and the negative edge-locking head 6. The recycling pipe 15 can extract the waste head impurities generated during sewing, preventing the waste head impurities from accumulating on the equipment and affecting the production of the welt.

[0040] Specifically, as Figure 1 , Figure 7 shown, the straight sewing mechanism 2 includes a straight sewing member 24, a second fabric pulling assembly 25, and a second synchronization assembly 26 provided on the frame. The second fabric pulling assembly 25 in this embodiment has the same structure as the first fabric pulling assembly 8, and the second synchronization assembly 26 has the same structure as the first synchronization assembly 27. The second synchronization assembly 26 and the first synchronization assembly 27 are for coordinating the speed difference between the operation of the straight sewing mechanism 2 and the edge-locking mechanism 3.
