Description

Technical Field

[0001] This utility model relates to the field of garment production technology, specifically to a device for cleaning burrs at the seams of garment fabrics. Background Technology

[0002] In the garment manufacturing industry, short-sleeved tops are a frequently worn item, and their sewing quality directly affects the product's comfort and market competitiveness. During the sewing process of short-sleeved tops, the shoulder and side waist areas are critical seam areas. Due to factors such as layered fabric sewing, variations in thread tension, and the inherent characteristics of the fabric itself, burrs and imperfections are easily generated at the seam edges. These burrs not only cause itching when wearing the garment, affecting the wearing experience, but may also lead to quality problems such as loose threads and pilling during subsequent washing, reducing the garment's durability.

[0003] Currently, the industry commonly uses manual trimming to clean burrs at the shoulder and side waist seams of short-sleeved shirts. Operators must use scissors or blades to trim the burrs one by one. However, because short-sleeved shirts are mostly made of cotton, knitwear, or blends, which are highly soft and stretchy, the fabric is prone to wrinkling and deformation without proper support, making it difficult to locate the burrs. Operators must repeatedly adjust the fabric's position to ensure trimming accuracy, increasing labor intensity and making it difficult to guarantee consistent cleaning results.

[0004] In addition, manual operation carries the risk of fabric damage or incomplete trimming due to improper force control, which further affects the stability of product quality and also restricts the improvement of production efficiency, making it impossible to meet the needs of large-scale production.

[0005] Therefore, developing a device that can accurately locate and efficiently clean burrs at seams, taking into account the characteristics of soft fabrics in short-sleeved shirts, has become an urgent technical problem to be solved in the garment manufacturing industry. Utility Model Content

[0006] The purpose of this invention is to provide a device for cleaning burrs at the seams of clothing fabrics, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A device for cleaning burrs at the seams of garment fabric includes a workbench. A detachable upper garment mold is rotatably mounted on the workbench surface, and a U-shaped frame with adjustable position is slidably mounted on the upper surface of the workbench. Fixing plates are fixedly mounted on both the left and right sides of the upper surface of the U-shaped frame, respectively. A pneumatic telescopic rod A is fixedly mounted through the outer surface of each fixing plate. A cutter holder is fixedly mounted on one end of the pneumatic telescopic rod A near the upper garment mold. Multiple cutters are fixedly mounted on one side of the cutter holder, and the positions of the cutters on the cutter holder correspond to the seams of the upper garment fabric to be cleaned.

[0009] Preferably, a support shaft is rotatably mounted through the workbench, a support plate is fixedly mounted on the upper surface of the support shaft, the lower surface of the support plate is in contact with the upper surface of the workbench, and the garment mold is mounted on the support plate.

[0010] Preferably, two short rods and a long rod are fixedly installed on the upper surface of the support plate. A through hole is opened through the upper surface of the garment mold. The long rod is installed through the through hole, and a locking nut is screwed to the top of the long rod. The lower surface of the locking nut fits against the upper surface of the garment mold. Two slots are opened on the lower surface of the garment mold, and the two short rods are inserted into the corresponding slots.

[0011] Preferably, the workbench is equipped with a drive mechanism for rotating the support shaft. The drive mechanism includes a self-locking angle adjustment motor fixedly installed in the workbench and a driven gear sleeved on the outer surface of the support shaft. The output end of the self-locking angle adjustment motor is sleeved with a driving gear, and the driving gear and the driven gear are meshed together.

[0012] Preferably, I-shaped guide rails are fixedly installed on both the left and right sides of the upper surface of the workbench, and the left and right ends of the U-shaped frame are slidably connected to the corresponding I-shaped guide rails.

[0013] Preferably, a vertical plate is fixedly installed on the upper surface of the workbench, the vertical plate is located behind the upper garment mold, and a pneumatic telescopic rod B is fixedly installed between the vertical plate and the U-shaped frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting a detachable upper garment mold, and combining it with a dual positioning structure of short rods and long rods, as well as the rotational support of the support plate and the support shaft, makes the soft fabric evenly stretched, solving the problem of positioning difficulties caused by fabric wrinkles and deformation during manual operation, while ensuring the stability of the garment after it is put on.

[0016] By setting up a drive mechanism consisting of a self-locking angle adjustment motor, a drive gear, and a driven gear, the upper garment mold can be rotated precisely, replacing manual adjustment of the fabric posture, avoiding angle deviation, and ensuring that the burr cutting part is accurately aligned with the cutting blade.

[0017] By setting up an adjustable U-shaped frame with I-beam guide rails and using a pneumatic telescopic rod A to move and engage the cutting blade, the cutting blade can be adjusted smoothly and precisely at position 6 for burr removal. This replaces manual hand-held tools for trimming, avoiding missed or excessive cutting, ensuring that burrs are completely removed in one go, and effectively protecting the fabric from damage. This improves the consistency of cleaning results and production efficiency, meeting the needs of large-scale production. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution:

[0026] A device for cleaning burrs at the seams of garment fabric includes a workbench 1. A detachable upper garment mold 3 is rotatably mounted on the workbench 1, and a U-shaped frame 4 with adjustable position is slidably mounted on the upper surface of the workbench 1. Fixing plates 5 are fixedly mounted on both the left and right sides of the upper surface of the U-shaped frame 4, respectively. The two fixing plates 5 are located on the left and right sides of the upper garment mold 3, and a pneumatic telescopic rod A51 is fixedly mounted through the outer surface of the fixing plates 5. A cutter holder 52 is fixedly mounted on the end of the pneumatic telescopic rod A51 near the upper garment mold 3. Multiple cutters 6 are fixedly mounted on one side of the cutter holder 52, and the positions of the cutters 6 on the cutter holder 52 correspond to the seams of the upper garment fabric to be cleaned.

[0027] When using this method, the operator first pre-treats the short-sleeved shirt to be deburred by turning it inside out so that the burrs at the seams are fully exposed. Subsequently, the pre-treated short-sleeved shirt is placed on the shirt mold 3. The support of the shirt mold 3 allows the soft fabric to be evenly stretched. Then, the shirt mold 3 is rotated 90 degrees clockwise to adjust the burr cutting area so that the cutting blade 6 is facing the opposite direction. Next, the positions of the cutting blade 6 and the cutting blade holder 52 are adjusted back and forth using the U-shaped frame 4 to position the cutting blade 6 on the left and right sides of the garment. Then, the two pneumatic telescopic rods A51 are used to move the corresponding cutting blade 6 toward the garment. When the cutting blades 6 on both sides are engaged, the burrs on the garment are cut off. After the burr cleaning is completed, the position of the cutting blade 6 is reset using the pneumatic telescopic rods A51, and the garment can be manually removed from the shirt mold 3. The entire burr cleaning work is completed by the device, which ensures that the burrs are completely removed in one go, avoiding the problems of missed or excessive cutting during manual trimming. At the same time, it can effectively protect the fabric itself from damage.

[0028] Specifically, combined Figure 2 As shown, a support shaft 11 is rotatably installed through the workbench 1. A support plate 12 is fixedly installed on the upper surface of the support shaft 11. The lower surface of the support plate 12 is in contact with the upper surface of the workbench 1. The upper garment mold 3 is installed on the support plate 12. The support plate 12 is rotatably connected to the workbench 1 through the support shaft 11.

[0029] Two short rods 121 and a long rod 122 are fixedly installed on the upper surface of the support plate 12. A through hole 31 is opened through the upper surface of the upper garment mold 3. The long rod 122 is installed through the through hole 31, and a locking nut 123 is screwed to the top of the long rod 122. The lower surface of the locking nut 123 fits against the upper surface of the upper garment mold 3. Two slots 32 are opened on the lower surface of the upper garment mold 3. The two short rods 121 are inserted into the corresponding slots 32.

[0030] The detachable design of the top mold 3, combined with the dual positioning structure of the short rod 121 and the long rod 122, not only ensures the stability of the garment after it is put on, but also makes it easy to change the corresponding mold according to different sizes of short-sleeved tops, thus improving the versatility of the device.

[0031] When changing the upper garment mold 3, after unscrewing the locking nut 123, move the upper garment mold 3 upward to separate it from the long rod 122, and then you can replace it with a mold of the corresponding size.

[0032] Combination Figure 2 and Figure 4 As shown, a drive mechanism 2 for driving the support shaft 11 to rotate is installed inside the workbench 1. The drive mechanism 2 includes a self-locking angle adjustment motor 21 fixedly installed inside the workbench 1 and a driven gear 23 sleeved on the outer surface of the support shaft 11. A drive gear 22 is sleeved on the output end of the self-locking angle adjustment motor 21, and the drive gear 22 and the driven gear 23 are meshed together.

[0033] The self-locking angle adjustment motor 21 in the drive mechanism 2 is activated. The motor output drives the drive gear 22 to rotate. Through the meshing transmission between the drive gear 22 and the driven gear 23, the support shaft 11 and the support plate 12 are driven to rotate, thereby causing the upper garment mold 3 to rotate 90 degrees, so that the shoulder and side waist seams of the short-sleeved top are precisely aligned with the corresponding positions of the cutting blade 6. After the rotation is completed, the self-locking angle adjustment motor 21 automatically locks to ensure that the upper garment mold 3 maintains a stable angle.

[0034] Automated angle adjustment replaces manual adjustment of the fabric posture, avoiding angle deviations caused by manual rotation and resulting in higher alignment accuracy between the burr area and the cutting blade 6; the self-locking design ensures that the mold does not wobble during the cutting process, further improving the cutting stability.

[0035] like Figure 1 As shown, I-shaped guide rails are fixedly installed on both the left and right sides of the upper surface of the workbench 1. The left and right ends of the U-shaped frame 4 are slidably connected to the corresponding I-shaped guide rails. The U-shaped frame 4 is slidably installed on the workbench 1 through two I-shaped guide rails.

[0036] Finally, as Figure 1 As shown, two positioning blocks are fixedly installed on the upper surface of the workbench 1. The two positioning blocks are located in front of the corresponding I-shaped guide rails and are used to position the fixed plate 5. When the front and rear surfaces of the fixed plate 5 are in contact with the rear surface of the positioning block, it means that the cutting blade 6 has moved to the position corresponding to the cutting part.

[0037] A vertical plate 7 is fixedly installed on the upper surface of the workbench 1. The vertical plate 7 is located behind the upper garment mold 3, and a pneumatic telescopic rod B71 is fixedly installed between the vertical plate 7 and the U-shaped frame 4.

[0038] The pneumatic telescopic rod B71 between the control plate 7 and the U-shaped frame 4 extends. Under the guidance of the I-shaped guide rail on the upper surface of the workbench 1, the U-shaped frame 4 moves forward smoothly, simultaneously driving the fixed plate 5, the pneumatic telescopic rod A51, the cutter holder 52 and the cutter 6 to move towards the upper garment mold 3 until the cutter 6 reaches the preset cutting start position.

[0039] Pneumatic drive combined with I-shaped guide rails ensures smooth and seamless movement of the U-shaped frame 4, avoiding positional deviations of the cutting blade 6 caused by uneven force during manual pushing; preset positioning ensures consistent starting points for each cut, improving quality uniformity during mass production.
