[0001] The invention relates to the technical field of carpet processing, in particular to a carpet edge locking machine. Background Art

[0002] With the development of textile industry, carpet, as an important indoor decoration material, has been continuously improved in production and processing technology. In the production process of carpet, edge locking is a very important process, which not only ensures the beauty and durability of carpet, but also effectively prevents the edge of carpet from being worn and unthreaded.

[0003] Traditional carpet edge-locking machines are mostly manual or semi-automatic, which are inefficient and unstable in edge-locking effect. They are prone to wrinkles and unevenness, affecting the overall quality and market competitiveness of carpets. In recent years, the application of automation and intelligent technology has brought new opportunities for the development of carpet edge-locking machines.

[0004] Although the existing carpet edge-locking machines have improved production efficiency and edge-locking quality to a certain extent, they still have some shortcomings in actual operation. For example, the existing edge-locking machines often cannot solve the problem of carpet flatness during the edge-locking process, resulting in poor edge-locking effect and even a large number of defective products. In addition, the existing edge-locking machines have a cumbersome way to adjust the edge width, which is inconvenient to operate and difficult to meet the needs of carpets of different sizes and materials. Summary of the invention

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Example 1

[0026] A carpet edge locking machine, such as Figures 1 to 3As shown, it includes a base 1, a machine frame 2 and an equipment frame 8 are respectively provided on both sides of the base 1, an operating panel 3 is provided on the machine frame 2, a fixing seat 7 is provided on the equipment frame 8, a needle column 6 is provided above the operating panel 3 and near the fixing seat 7, and a flattening device is provided above the rear side of the operating panel 3, the flattening device includes a fixing plate 5, a U-shaped frame 9 located between the fixing plate 5 and the operating plate 3, flattening rollers 13 rotatably provided at both ends of the U-shaped frame 9, two guide rods 12 movably provided on the fixing plate 5, and a locking mechanism connected to the upper end of the guide rod 12, and both ends of the fixing plate 5 are connected by a support rod 4. The lower end of the guide rod 12 is connected to the operating panel 3, and is connected to the U-shaped frame 9. A compression spring 16 is sleeved on the guide rod 12 between the U-shaped frame 9 and the fixed plate 5. Under the elastic force of the compression spring 16, the flattening roller 13 is pushed by the compression spring 16 and pressed against the operating panel 3. Due to the retractability of the compression spring 16, the flattening roller 13 will not press the carpet against the operating panel 3 and cannot be dragged. The carpet becomes flat after passing through the flattening roller 13, reducing the wrinkles on the carpet, thereby avoiding affecting the locking effect. The two ends of the fixed plate 5 are fixed to the operating panel 3 through the support rod 4. The locking mechanism includes a connecting rod 10 connected to the top of the guide rod 12, and a sliding rod respectively fixed to the upper surface of the fixed plate 5 and located outside the guide rod 12. The sliding rod is slidably penetrated on the connecting rod 10, and a plurality of plug holes 14 are opened on the sliding rod. The connecting rod 10 is provided with a plug rod 15 that cooperates with the plug hole 14. The flattening roller 13 can be fixed at a corresponding position by the cooperation of the insertion rod 15 and the connecting rod 10, so that the carpet can be placed below the flattening roller 13. A limit block 11 is provided on the top of the slide bar. The limit block 11 can prevent the connecting rod 10 from slipping out of the slide bar when moving up and down.

[0027] A locking piece 18 is provided on one side of the needle column 6, a slide groove 19 is provided on the bottom of the fixed seat 7 near the operation panel 3, the locking piece 18 is provided in the slide groove 19, and an adjusting device for adjusting the locking width is connected to one end of the slide groove 19 inside the fixed seat 7. The adjusting device includes a moving groove 20 provided on the lower surface of the fixed seat 7 and connected to the slide groove 19, a wedge block 21 connected to one end of the locking piece 18 is provided in the moving groove 20, the upper end surface of the wedge block 21 is inclined, a connecting groove 22 is provided above the moving groove 20 in the fixed seat 7, a threaded rod 23 is threadedly connected to the upper end of the fixed seat 7, a knob 24 is connected to the top of the threaded rod 23, and an adjusting block 28 is connected to the bottom, the bottom surface of the adjusting block 28 is curved, and the adjusting block 28 with a curved bottom surface can reduce the friction with the inclined surface of the wedge block 21. A reset groove 25 is provided on the upper surface of the equipment frame 8, and a reset block 26 whose top is connected to the wedge block 21 is slidably provided in the reset groove 25, and a reset spring 27 is connected between one end of the reset block 26 and the inner wall of the reset groove 25 near the slide groove 19. The threaded rod 23 is rotated by turning the knob 24, so that the adjustment block 28 moves up and down in the connecting groove 22. When moving downward, the wedge block 21 is pushed to move leftward, thereby adjusting the length of the edge lock piece 18 extending out of the slide groove 19. When the adjustment block 28 moves upward, under the action of the reset spring 27, the wedge block 21 moves rightward, thereby driving the edge lock piece 18 to move into the slide groove 19, and then adjusting the length of the edge lock piece 18 extending out, thereby adjusting the edge lock width of the carpet. A scale line 17 is provided below the edge lock piece 18 on the operation panel 3. The length of the edge lock piece 18 extending out of the slide groove 19 can be determined according to the scale line 17, so as to accurately adjust the edge lock width.

[0028] When the present invention is used, first, the carpet is laid on the operating plate 3, then the insertion rod 15 on the connecting rod 10 is pulled out, the restriction on the guide rod 12 is released, the flattening roller 13 is lowered to press the carpet, and the flattening roller 13 presses the carpet on the operating plate 3 under the action of the compression spring 16. When locking the edge, the carpet is pulled while locking the edge. The carpet is locked after being pulled over by the flattening roller 13, which can prevent the carpet from being uneven, thereby reducing the generation of defective products and improving the quality of locking the edge. After the locking edge is completed, the connecting rod 10 is pulled upward to lift the U-shaped frame 9 and the flattening roller 13 upward together, and then the insertion rod 15 is inserted into the corresponding insertion hole 14, so that the connecting rod 10 is fixed on the sliding rod, and then the position of the flattening roller 13 is limited, so that the carpet with locked edge can be taken out; then the threaded rod 23 is rotated by rotating the knob 24 in the forward or reverse direction, driving the adjusting block 28 to move upward or toward the connecting groove 22. The adjusting block 28 is pressed against the bottom surface of the adjusting block 28, so that one end of the locking edge piece 18 is adjusted in the slide groove 19, and the extending distance of the locking edge piece 18 can be determined according to the scale line 17 on the operating panel 3, thereby adjusting the locking edge width of the carpet.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
