Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of luggage processing equipment, in particular to a fabric stretching device for luggage fabric cutting. BACKGROUND

[0002] In the process of making luggage, fabric cutting is a key process. In traditional luggage fabric cutting operations, the fabric is usually laid flat on the cutting table by hand, and then the fabric is pulled flat and fixed by hand to facilitate subsequent precise cutting. However, this manual operation has many drawbacks. On the one hand, manual fabric stretching cannot ensure uniform tension of the fabric everywhere, which can cause deviations in the size of the cut fabric and affect the sewing quality and appearance of the finished product. For example, when making high-end leather luggage, if the fabric cutting size is not accurate, the luggage will have problems such as uneven joint gaps and loose parts when assembled, reducing product quality. On the other hand, manual stretching for a long time is labor-intensive and inefficient, which is not conducive to large-scale industrial production. With the growing demand for luggage, the demand for production efficiency and product quality is increasing, and there is an urgent need for a device that can efficiently and accurately stretch fabric to replace traditional manual operation.

[0003] A fabric cutting and stretching device is disclosed in Chinese Patent No. 2022236037812, which includes a long rod-shaped fabric stretching guide, the inside of the fabric stretching guide is provided with a left and right end interconnected sliding groove, and the front is provided with an adapter port interconnected with the sliding groove; The sliding groove is provided with at least two sliding blocks that can slide left and right, each sliding block is fixedly provided with an adjusting arm that extends outside the front of the fabric stretching guide through the adapter port, the adjusting arm is provided with a fabric clamping head on one side for clamping the fabric, and the other side is provided with a roller, and the back of the fabric stretching guide is provided with a main handle near the top center.

[0004] For the related technology in the above, the inventors found that the above-mentioned patent cannot quickly release the fixation of the fabric after cutting. Practical new type content

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a fabric spreading device for cutting bag fabrics. For example... Figure 1 , 2As shown in Figure 3, the support platform 1 is used for laying fabric flat. Positioning strips are provided near the four edges of the support platform 1, and fixing strips 16 are provided on the positioning strips to cooperate with and fix the edges of the fabric. Fixing seats 2 are bolted to all four sides of the support platform 1. Multiple fixing seats 2 are evenly spaced. The fixing seats 2 are connected to the fixing strips 16 via fixing rods 17, which are hinged together. The fixing rods 17 have fixing strips 16 screwed to the end furthest from the fixing seats 2. A slot 3 is provided within the fixing strip 16. A clamping strip 4 is hinged to one side wall of the slot 3, and a clamping plate is hinged to the other side wall. Both the clamping strip 4 and the clamping plate are rectangular plate structures, symmetrically arranged about the center line of the slot 3. A spring is installed between the clamping bar 4 and the clamping plate. Clamping blocks 14 are screwed to both sides of the clamping bar 4 and the clamping plate at the end furthest from the slot 3. The clamping blocks 14 are rectangular blocks connected by a spring, and a cover 15 is fitted over the spring. An airbag column 6 is installed inside the slot 3. The airbag column 6 is existing technology, and its outer wall is covered with an elastic mesh. One end of the elastic mesh is glued to the fixing bar 16. When the airbag column 6 is inflated, the spring is stretched, and the two clamping bars 4 are pushed away from each other by the airbag column 6. An air pump connected to the airbag column 6 is installed on the support platform 1. The air pump is electrically connected to a power source via a switch, and the air pump and airbag column 6 are connected via an air tube.

[0023] In one embodiment, according to the appendix Figure 3 As shown, a recessed area 7 is provided inside the clamping plate. The recessed area 7 has a rectangular cross-section and is located in the middle of the clamping plate. Multiple long shafts 8 are rotatably connected within the recessed area 7 and are evenly spaced along the width of the recessed area 7. Each long shaft 8 is fitted with a positioning block for fixing the fabric. Multiple positioning blocks are evenly spaced along the length of the long shaft 8. The ends of each long shaft 8 extend to the outside of the clamping plate and are hinged with insertion rods 12. The insertion rods 12 have an "L" shape. Multiple slots are provided on the side of the clamping plate to cooperate with the positioning rods 9 and to fix the rotation angle of the long shafts 8. These slots are centrally symmetrical about the center of the long shafts 8.

[0024] In one embodiment, according to the appendix Figure 4 As shown, the positioning block includes a positioning rod 9 and a positioning ball 10. The positioning rod 9 has a through hole for the long shaft 8 to pass through, and the positioning rod 9 is glued to the long shaft 8. The cross-section of the long shaft 8 located in the recessed area 7 is a regular hexagon. An extension rod 11 integrally formed with the positioning ball 10 is provided. The positioning rod 9 has a sliding hole that cooperates with the extension rod 11. The sliding hole has a circular cross-section. An elastic protrusion is provided on the extension rod 11. A fixing groove that cooperates with the elastic protrusion is provided in the sliding hole. There are multiple fixing grooves, which are evenly spaced along the length of the sliding hole.

[0025] The implementation principle of the fabric pulling device for cutting bag fabric in this embodiment is as follows: The bag fabric to be cut is transported to the top of the support platform, with the four edges of the fabric corresponding to the positioning strips on the four sides of the support platform. Then, the air pump is started to inflate the air chamber, causing it to expand and compress the spring, thus moving the clamping strip and clamping plate away from each other. At this point, the edge of the fabric is easily placed into the slot of the fixing strip. Next, the air pump is operated to deflate the air chamber, causing the spring to contract and driving the clamping strip and clamping plate to move towards each other, tightly clamping the edge of the fabric. At the same time, the clamping strip, clamping plate, and positioning block in the slot work together to firmly fix the fabric on the support platform. According to the cutting requirements, the operator can selectively rotate the long shaft to adjust the angle of the positioning block, so that the positioning block can better act on the key parts of the fabric, further enhancing the fixing effect.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
