Description

Technical Field

[0001] This invention relates to the field of fabric finishing technology, and in particular to a device and operating method for finishing the edges of clothing fabrics. Background Technology

[0002] With the improvement of living standards, people have become more and more demanding in terms of aesthetics, which has led to garment factories now trimming the edges of fabrics before processing them.

[0003] A fabric trimming device and method for fabric embroidery before embroidery, disclosed in CN112226985B, can process fabrics of different thicknesses and automatically collect the processed fabrics without manual intervention. It can completely solve the problem of fabric edges and has high processing efficiency. This device uses a cylinder to drive a serrated cutter to trim the edges of the fabric, cutting the edges into a serrated shape. This serrated edge can effectively prevent the fabric edges from coming loose during embroidery. However, it is difficult to ensure that the blades of the serrated cutter pressing down at the front and rear are exactly connected when using the device, and the two ends of the blades need to be adjusted according to the coverage of the fabric during trimming to achieve a good edge trimming effect.

[0004] To address the aforementioned problems, a garment fabric edge trimming device and its operating method are proposed. Summary of the Invention

[0008] Furthermore, the fabric fixing mechanism also includes fabric rollers and trimming winding assemblies respectively fixed to the upper ends of the two sets of side openings. The trimming winding assembly includes a transmission frame and a mounting frame fixedly disposed on both sides of the upper end of the fixed support frame. A rotating sleeve is threadedly connected to one side of the transmission frame and the mounting frame. Four sets of rotating sleeves are provided. Two sets of winding rods are rotatably fixed between the four sets of rotating sleeves. One end of the two sets of winding rods is connected to a transmission belt. A winding rod is connected to one side of the transmission belt. The fabric roller is an assembly consisting of two sets of rotating sleeves and one set of winding rods movably connected.

[0009] Furthermore, the leveling conveying mechanism includes a conveying fixed frame fixedly installed on the upper end of the fixed support frame, a lifting block movably installed inside the conveying fixed frame, a threaded rod connected to one side of the lifting block, and two sets of the rolling components respectively passing through and fixed on the conveying fixed frame and the lifting block. The rolling components include gears fixedly installed on one side of the conveying fixed frame and the lifting block, and a roller connected to the center of the gear.

[0010] Furthermore, limit rods are fixed on both sides of the inside of the guide rail frame, the drive cylinder drives the lifting slide plate to rise and fall, the lifting slide plate is provided with an insertion port, and the limit rod is movably inserted into the insertion port.

[0011] Furthermore, the trimming and pressing assembly includes two sets of upper spring sleeve rods connected to the lifting slide plate, a spring connecting plate fixed between the two sets of upper spring sleeve rods, and a pressing shaft fixedly installed at the lower end of the spring connecting plate. The lower end of the pressing shaft is provided with trimming knife slots arranged side by side.

[0012] Furthermore, the trimming blade adjustment assembly includes two sets of double-sided spring sleeve rods connected to the lifting slide plate, which are sleeved on a slide rail between the springs at both ends of the double-sided spring sleeve rods. The slide rail has a horizontal sliding opening, and a scale is provided on one side of the horizontal sliding opening.

[0013] Furthermore, the trimming tool adjustment assembly also includes a trimming curved blade that is slidably disposed within a horizontal sliding opening.

[0015] Another technical solution proposed by the present invention: A method for operating a garment fabric edge trimming device, comprising the following steps:

[0016] S1: Fix the garment fabric; control the lifting slide to raise the fabric in sequence onto the fabric roller, edge trimming mechanism and trimming winding assembly.

[0017] S2: Adjusting the trimming position: Pull down the slide rail and adjust the trimming bevel according to the ruler and the fixed position of the garment fabric. After adjustment, release the trimming bevel so that the trimming bevel automatically engages into the trimming bevel slot and is fixed.

By combining a flattening conveying mechanism and an edge trimming mechanism, two sets of rolling components mesh and squeeze each other, so that the garment fabric can be flattened and pressed. The upper height of the lower trimming table is equal to the height of the rolling components at the lower end, which facilitates the flat conveying of the garment fabric through the trimming position. This solves the problem that existing fabric edge trimming devices are difficult to ensure that the serrated cutter blades pressing down at the front and rear are connected precisely.

[0021] 2. The present invention provides a garment fabric edge trimming device and operating method. Through the coordinated arrangement of the trimming pressing component and the trimming blade adjustment component within the edge trimming mechanism, when the lifting slide is at its highest position, the trimming blade adjustment component is pulled downwards. The trimming blade can move along the slide rail to adjust the trimming position of the garment fabric. After adjustment, the trimming blade adjustment component is released, allowing the lower end of the trimming blade to automatically engage with the pressing shaft, thus achieving trimming positioning of the trimming blade. When the device begins trimming, the lifting slide is at its lowest position, and the pressing shaft contacts the lower trimming table, achieving compression and fixation of both sides of the trimming blade during trimming. This structure allows the garment fabric in the device to be trimmed under compression from both sides, making the trimming process smoother and ensuring trimming effect. It solves the problem that existing fabric edge trimming devices require the blades at both ends to be adjusted according to the fabric's coverage position to achieve good edge trimming results.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In order to solve existing technical problems, such as Figures 1-6 As shown, the following preferred technical solutions are provided:

[0031] A garment fabric edge trimming device and operating method include a fabric fixing mechanism 1, a flattening conveying mechanism 2 fixedly mounted on the upper end of the fabric fixing mechanism 1, and an edge trimming mechanism 3 fixedly mounted on the upper end of the fabric fixing mechanism 1. The flattening conveying mechanism 2 includes two sets of rolling components 24 that mesh with each other and are arranged in parallel. The garment fabric to be cut is placed between the two sets of rolling components 24. The edge trimming mechanism 3 includes a guide rail frame 31 fixedly connected to the fabric fixing mechanism 1, a drive cylinder 32 fixedly mounted on one side of the guide rail frame 31, and a drive cylinder 32. The telescopic end of the 32 has a lifting slide plate 33. The lower end of the lifting slide plate 33 is fixedly provided with a trimming and pressing component 34 and a trimming knife adjustment component 35. The lower end of the trimming and pressing component 34 and the trimming knife adjustment component 35 is provided with a lower trimming table 36 fixedly connected to the fabric fixing mechanism 1. The trimming and pressing component 34 includes a liftable pressing shaft 343. The trimming knife adjustment component 35 includes a slide rail 352 that is elastically connected to the lifting slide plate 33. A trimming curved knife 353 is provided inside the slide rail 352. The lower end of the trimming curved knife 353 is engaged in the pressing shaft 343.

[0032] Specifically, the two sets of rolling components 24 mesh and press against each other, allowing the garment fabric to be flattened and pressed. The upper height of the lower trimming table 36 is equal to the height of the rolling components 24 at the lower end, facilitating the flat conveying of the garment fabric. The guide rail frame 31 fixes the drive cylinder 32. The extension and retraction of the drive cylinder 32 causes the lifting slide plate 33 to rise and fall vertically. The trimming and pressing component 34 is elastically connected to one side of the lifting slide plate 33. The trimming knife adjustment component 35 is located on one side of the trimming and pressing component 34. Two sets of trimming curved knives 353 are provided. When the lifting slide plate 33 is in the highest position, the trimming knife adjustment component 35 is pulled downward. The trimming cutter 353 can move along the slide rail 352 to adjust the trimming position of the garment fabric. After adjustment, the trimming cutter adjustment component 35 is released, so that the lower end of the trimming cutter 353 can automatically engage with the pressure shaft 343, thus achieving the trimming positioning of the trimming cutter 353. When the equipment starts trimming, the lifting slide plate 33 is set to the lowest position, and the pressure shaft 343 and the lower trimming table 36 are in contact with each other, so as to squeeze and fix the two sides of the trimming cutter 353 during trimming. This structure allows the garment fabric in the device to be trimmed under the pressure on both sides, making the trimming process smoother and ensuring the trimming effect.

[0033] The fabric fixing mechanism 1 includes a fixing support frame 11, with side openings 111 on both sides of the fixing support frame 11. The fixing support frame 11 fixes the flattening conveying mechanism 2 and the edge trimming mechanism 3. The side openings 111 allow the garment fabric to be rolled up at both ends before and after processing.

[0034] The fabric fixing mechanism 1 also includes fabric rollers 12 fixed to the upper ends of two sets of side openings 111 and trimming and winding assembly 13. The trimming and winding assembly 13 includes a transmission frame 131 and a mounting frame 132 fixedly mounted on both sides of the upper end of the fixed support frame 11. A rotating sleeve 133 is threadedly connected to one side of the transmission frame 131 and the mounting frame 132. There are four sets of rotating sleeves 133. Two sets of winding rods 136 are rotatably fixed between the four sets of rotating sleeves 133. One end of the two sets of winding rods 136 is connected to a transmission belt. 135, a winding rod 136 is connected to one side of the transmission belt 135. The fabric roller 12 is an assembly consisting of two sets of rotating sleeves 133 and one set of winding rods 136 connected movably. The fabric roller 12 fixes the garment fabric before finishing. The transmission frame 131 and the mounting frame 132 play a fixing role. The winding drive motor 134 is connected to the fixed support frame 11. The drive transmission belt 135 drives the two sets of winding rods 136 to rotate in the same direction, realizing the synchronous winding of the finished fabric and the finished waste, and ensuring the flatness during finishing.

[0035] The leveling conveying mechanism 2 includes a conveying fixed frame 21 fixedly mounted on the upper end of the fixed support frame 11. A lifting block 22 is movably mounted inside the conveying fixed frame 21. A threaded rod 23 is connected to one side of the lifting block 22. Two sets of rolling components 24 are respectively fixed through the conveying fixed frame 21 and the lifting block 22. The rolling components 24 include gears 241 fixedly mounted on one side of the conveying fixed frame 21 and the lifting block 22, and a roller 242 connected to the center of the gears 241. The rotation of the threaded rod 23 drives the lifting block 22 to move horizontally along the conveying fixed frame 21. The distance between the two sets of rollers 242 can be adjusted according to the fabric thickness. The meshing tooth width between the gears 241 is greater than the thickest thickness of the garment fabric to ensure the meshing effect.

[0036] Limiting rods 311 are fixed on both sides of the inside of the guide rail frame 31. The drive cylinder 32 drives the lifting slide plate 33 to rise and fall. The lifting slide plate 33 has a socket 331. The limiting rods 311 are movably inserted into the socket 331. The combination of the limiting rods 311 and the socket 331 limits the rise and fall of the lifting slide plate 33, restricting its vertical rise and fall and keeping it in a horizontal state.

[0037] The trimming and pressing assembly 34 includes two sets of upper spring sleeve rods 341 connected to the lifting slide plate 33, a spring connecting plate 342 fixed between the two sets of upper spring sleeve rods 341, and a pressing shaft 343 fixedly installed at the lower end of the spring connecting plate 342. The lower end of the pressing shaft 343 is provided with trimming knife slots 3431. The springs sleeved on the upper spring sleeve rods 341 provide a certain elastic force to the spring connecting plate 342 to prevent the garment fabric from being completely pressed down by the pressing shaft 343 and unable to be rolled up.

[0038] The trimmer adjustment assembly 35 includes two sets of double-sided spring-loaded connecting rods 351 connected to the lifting slide plate 33, which are connected to a slide rail 352 between the springs at both ends of the double-sided spring-loaded connecting rods 351. The slide rail 352 has a horizontal sliding opening 3521, and a scale 3522 is provided on one side of the horizontal sliding opening 3521. The springs at both ends of the double-sided spring-loaded connecting rods 351 make the slide rail 352 easy to pull. The horizontal sliding opening 3521 provides an adjustment track for the trimmer bevel 353, and the scale 3522 indicates the adjustment distance.

[0039] The trimming cutter adjustment assembly 35 also includes a trimming curved cutter 353 that is slidably disposed in the horizontal sliding port 3521. The trimming curved cutter 353 can be adjusted in position when the slide rail 352 is pulled downward. After adjustment, the slide rail 352 is released, and the trimming curved cutter 353 will engage with the trimming cutter slot 3431 for fixation.

[0040] The lower trimming table 36 has blades 361 arranged side by side with the trimming curved blade 353 at the adjustment position. A rounded corner 362 is provided on one side of the lower trimming table 36. The combination of blades 361, trimming blade slots 3431 and trimming curved blade 353 ensures that the garment fabric is completely pressed during edge trimming, ensuring the trimming effect. The rounded corner 362 allows the trimmed waste material to be smoothly transported.

[0041] To further explain the above embodiments, the present invention also provides an implementation scheme, a garment fabric edge trimming device and operating method, comprising the following steps:

[0042] Step 1: Fix the garment fabric; control the lifting slide plate 33 to rise, and sequentially attach the fabric to the fabric roller 12, the edge trimming mechanism 3 and the trimming winding assembly 13.

[0043] Step 2: Adjusting the trimming position: Pull down the slide rail 352, and adjust the trimming curved blade 353 according to the ruler 3522 and the fixed position of the garment fabric. After adjustment, release the trimming curved blade 353 so that the trimming curved blade 353 automatically engages and is fixed in the trimming blade slot 3431.

[0044] Step 3: Start edge trimming: Control the trimming pressing component 34 to press down, and the trimming winding component 13 starts to wind, causing the garment fabric to move smoothly and pass through the trimming curved blade 353 to achieve trimming.
