Description

Technical Field

[0001] The invention relates to the technical field of fabric processing, in particular to a plucking and sewing device and process for producing fleece-lined sweatshirts. Background Art

[0002] The fleece-lined sweatshirt has become a popular clothing item in the autumn and winter seasons due to its softness and warmth. It is widely used in sportswear, home wear and daily casual wear. Its core technology lies in the plucking of the inner side of the fabric and precise sewing. The plucking process forms a soft and dense fleece layer on the surface of the fabric fiber through mechanical action, which not only enhances the warmth retention of the clothing, but also significantly improves the comfort and skin-friendly feel of wearing.

[0003] In the traditional production process, plucking and sewing are usually two independent steps. The fabric needs to be plucked first, and then transferred to the sewing process to complete the splicing. This separate process has obvious disadvantages. First, the process of manual feeding, plucking and sewing requires multiple stages. The separation of multiple processes leads to low production efficiency and increases operation time and cost; secondly, after the plucking process is completed, the fabric is easily damaged by external forces such as compression and friction during transfer and storage, resulting in a decrease in fluffiness and uneven plush effect, thereby affecting the warmth and appearance of the clothing. Therefore, in order to solve the above-mentioned problems, a plucking and sewing device and process for the production of inner fleece sweatshirts are designed. Summary of the invention

[0033] The positioning assembly 4 includes a mounting plate 41, one end of which is fixedly connected to the side wall of the moving block 32, the upper end of the mounting plate 41 away from the moving block 32 is rotatably connected to a gear 42, the middle of the upper end of the gear 42 is fixedly connected to a No. 4 threaded rod 43, the upper end of the No. 4 threaded rod 43 is threadedly connected to a moving frame 44, the front of the moving frame 44 is fixedly connected to a mounting frame 45, the front of the mounting frame 45 is slidably connected to the side wall of the moving block 32, and the upper ends of both sides of the mounting frame 45 are fixedly connected to positioning clamps 46.

[0034] The front part of the gear 42 meshes with the No. 1 gear plate 47, and the lower end of the No. 1 gear plate 47 is fixedly connected to the support block 48. The No. 1 gear plate 47 is used to drive the gear 42 to rotate, so that the gear 42 drives the No. 4 threaded rod 43 to rotate, so that the moving frame 44 drives the mounting frame 45 to move, and the mounting frame 45 drives the positioning clamping plate 46 to move, so that the positioning clamping plate 46 descends to clamp the fabric, which is convenient for plucking the fabric after it is fixed.

[0035] Embodiment 2

[0036] See also Figure 1 , Figure 4 and Figure 5 , further improvements were made on the basis of Example 1:

[0037] A fixing frame 8 is installed on the upper end of the base 1 near both sides of the sewing machine body 2, and a plucking assembly 6 is installed on the upper end of the fixing frame 8. The plucking assembly 6 includes a No. 2 threaded rod 62, and the No. 2 threaded rod 62 is rotatably connected to the fixing frame 8. A number of slots 81 are equidistantly provided on the fixing frame 8 with the No. 2 threaded rod 62 as the center. The lower end of the No. 2 threaded rod 62 is threadedly connected to the support frame 63, and the middle part of the lower end of the support frame 63 is rotatably connected to the plucking brush roller 64. The plucking brush roller 64 is used to pull out the fluff on the fabric. The rear part of the plucking brush roller 64 is fixedly connected to the output end of the No. 2 servo motor 65, and the No. 2 servo motor 65 is fixedly connected to the side wall of the support frame 63.

[0038] The plucking brush roller 64 used needs to be adjusted according to the type of fabric and the amount of plucking. In order to facilitate the adjustment of the height of the plucking brush roller 64, a fixed groove is also opened at the upper end of the No. 2 threaded rod 62, and a slider 611 is slidably connected in the fixed groove. The upper end of the slider 611 is fixedly connected to the turning handle 61, and the lower end of the slider 611 is fixedly connected to the elastic sheet 612. The elastic sheet 612 is a tension spring, and the lower end of the elastic sheet 612 is fixedly connected to the fixed groove. The two sides of the lower end of the turning handle 61 are fixedly connected to the plug rod 613, and the plug rod 613 is plugged into the slot 81.

[0039] When in use, first pull the turning handle 61 so that the turning handle 61 drives the slider 611 to rise and drives the elastic sheet 612 to extend. At the same time, the turning handle 61 drives the insertion rod 613 to separate from the slot 81. At this time, the turning handle 61 is no longer limited by the insertion rod 613. Then turn the turning handle 61 to make the turning handle 61 drive the slider 611 to rotate, and the slider 611 drives the No. 2 threaded rod 62 to rotate, so that the No. 2 threaded rod 62 drives the support frame 63 to rise or fall, thereby slightly adjusting the height of the plucking brush roller 64, so that the plucking brush roller 64 can be adjusted and used according to needs. Then release the turning handle 61, so that the elastic sheet 612 drives the slider 611 to recover, so that the turning handle 61 drops, and drives the insertion rod 613 to be plugged into the slot 81 again.

[0040] In order to prevent the support frame 63 from shaking when the second threaded rod 62 drives the support frame 63 to rise and fall, telescopic frames 66 are fixedly connected to both sides of the upper end of the support frame 63, and the upper end of the telescopic frame 66 is fixedly connected to the fixed frame 8. The telescopic frame 66 is composed of a limit frame and a limit plate. The limit frame is slidably connected to the limit plate, and the lower end of the limit frame is fixedly connected to the support frame 63, and the upper end of the limit plate is fixedly connected to the fixed frame 8. Figure 4 shown.

[0041] Embodiment 3

[0042] See also Figure 1 and Figure 5 , further improvements were made on the basis of Example 2:

[0043] An auxiliary material unloading assembly 5 is installed at the upper end of the base 1. The auxiliary material unloading assembly 5 includes two sets of pulleys 51 that are symmetrically arranged. A transmission belt 52 is installed on the pulleys 51 on the same side. One end of the pulley 51 away from the middle of the base 1 is fixedly connected to a No. 3 threaded rod 53. One side of the No. 3 threaded rod 53 is threadedly connected to a moving tube 54. One side of the moving tube 54 is fixedly connected to a No. 2 gear plate 55.

[0044] The lower end of the moving tube 54 is connected to the limiting rod 56, and the lower end of the limiting rod 56 is slidably connected to the base 1. The limiting rod 56 is provided to limit the moving tube 54, so that when the No. 3 threaded rod 53 drives the moving tube 54 to move, the moving tube 54 can only move horizontally, ensuring the stability of the moving tube 54 driving the No. 2 gear plate 55 to move.

[0045] By utilizing the auxiliary unloading component 5, after the fabric is sewn, the gear 42 can be actively driven to rotate, so that the gear 42 drives the No. 4 threaded rod 43 to rotate, and the upper movable frame 44 drives the mounting frame 45 to rise. After the positioning clamp 46 rises, it no longer clamps the fabric, so that the fabric can be removed, which is convenient for taking out the fabric after sewing.

[0046] One side pulley 51 is fixedly connected to the output end of the No. 3 servo motor 57, and the No. 3 servo motor 57 is fixedly connected to the base 1. The No. 3 servo motor 57 provides power to the pulley 51, prompting multiple No. 3 threaded rods 53 to drive the moving tube 54 to move, so that the No. 2 gear plate 55 moves.

[0047] The mounting blocks 10 are fixedly connected to both sides of the sewing machine body 2, and the rear of the mounting blocks 10 is fixedly connected to the electric push rod 9. The electric push rod 9 drives the mounting blocks 10 to move, so that the mounting blocks 10 drive the position of the sewing machine body 2 to adjust the position of the sewing fabric of the sewing machine 2.

[0048] The method of using the present invention is as follows: two fabrics that need to be plucked are placed on the moving plates 7 on both sides respectively, and are laid flat on the moving plates 7, and then the No. 1 servo motors 3 on both sides are started, so that the No. 1 servo motor 3 drives the No. 1 threaded rod 31, and the No. 1 threaded rod 31 drives the moving block 32 to move, so that the moving block 32 drives the moving plate 7 to move, and the moving plate 7 drives the fabric to move close to the middle of the sewing machine body 2, and at the same time, the moving block 32 also drives the mounting plate 41 and the gear 42 of the positioning assembly 4 to move, and when the gear 42 moves, it will mesh with the No. 1 gear plate 47 on one side, so that the gear 42 rotates and drives the No. 4 threaded rod 43 to rotate, and the No. 4 threaded rod 43 drives the moving frame 44 to descend, so that the moving frame 44 drives the mounting frame 45 to descend, and the mounting frame 45 drives the positioning clamping plate 46 to descend, and the positioning clamping plate 46 clamps the fabric on the moving plate 7 after it descends, so that the fabric is fixed at the four corners, so that the fabric automatically completes the limit clamping;

[0049] Then the moving block 32 continues to drive the moving plate 7 to move, so that the fabric moves and passes through the plucking brush roller 64, and before that, the second servo motor 65 needs to be started again, so that the second servo motor 65 drives the plucking brush roller 64 to rotate and plucking the fluff on the surface of the fabric;

[0050] Then, the two moving plates 7 drive the plucked fabrics to move to the lower end of the sewing machine body 2, and then the sewing machine body 2 is started to sew the two fabrics together to form a whole, and then the No. 3 servo motor 57 is started to drive the No. 3 servo motor 57 to drive the pulleys 51 on both sides to rotate, and the pulleys 51 are driven by the transmission belt 52 to rotate at the same time, and drive the No. 3 threaded rod 53 to rotate, and the No. 3 threaded rod 53 drives the moving tube 54 to move, so that the moving tube 54 drives the No. 2 gear plate 55 to move, and the No. 2 gear plate 55 moves and drives the gear 42 located on one side of the moving block 32 to rotate, and the gear 42 rotates and drives the No. 4 threaded rod 43 to rotate, and the No. 4 threaded rod 43 drives the moving frame 44 to rise, so that the moving frame 44 drives the mounting frame 45 to rise, and the mounting frame 45 drives the positioning clamping plate 46 to rise, so that the positioning clamping plate 46 is separated from the fabric after rising, and then the fabric can be taken out;

[0051] Then, the No. 3 servo motor 57 is started again, so that the pulley 51 drives the No. 3 threaded rod 53 to rotate, and the No. 3 threaded rod 53 drives the moving tube 54 to move and recover, and the moving tube 54 drives the No. 2 gear plate 55 to move and drives the gear 42 to rotate, so that the gear 42 drives the No. 4 threaded rod 43 to rotate, and the No. 4 threaded rod 43 drives the moving frame 44 to descend, so that the positioning clamp 46 descends, and then the No. 1 servo motor 3 is started again, so that the No. 1 threaded rod 31 drives the moving block 32 to move, and drives the moving plate 7 to move to the side away from the sewing machine body 2, so that the fabric can be fed and used again, and this reciprocating process can be performed.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
