Description

Technical Field

[0001] This utility model relates to the field of fabric cutting equipment technology, specifically a cutting device for processing ski jackets. Background Technology

[0002] As a core piece of equipment for skiing, ski jackets need to possess multiple functions, including windproofing, waterproofing, breathability, and warmth. Their special functional fabrics and complex pattern designs place extremely high demands on the precision and efficiency of cutting during the garment manufacturing process. Precise cutting not only ensures the functionality and comfort of the various components of the ski jacket after assembly, but also effectively reduces fabric waste and improves production efficiency.

[0003] According to a search, Chinese patent document CN212978454U discloses a fabric cutting device. The device involves laying the fabric flat on a worktable, then moving the blade to the desired cutting position. To facilitate movement, the locking bolt is loosened, and the limiting rod is moved to the resting end. The blade can then be moved to the desired cutting position by moving the slider. When the blade reaches the desired cutting position, the locking bolt is tightened, so that the bottom end of the locking bolt passes through the slider and abuts against the transverse slide rail, locking the slider. The frame is then rotated, causing the limiting rod to rotate to the pressing end, where two pressing rollers press the fabric firmly. The hydraulic pump is then energized, and the hydraulic rod pushes the blade downwards, cutting the fabric through the slit. The hydraulic pump then moves the blade upwards, completing the fabric cutting process.

[0004] However, the above-mentioned cutting device cannot achieve automatic feeding in actual use and needs to rely on manual feeding, which is not conducive to improving the cutting efficiency of the fabric. Utility Model Content

[0014] Compared with the prior art, the present invention provides a cutting device for processing ski jackets, which has the following advantages:

[0015] 1. This utility model places the fabric between the cutting board and the pressure roller before cutting.

This provides a reliable foundation for subsequent precise cutting, effectively avoids cutting deviations caused by unstable fabric fixation, and ensures the smooth progress of the cutting work.

[0016] 2. In this utility model, after one cut is completed, the No. 3 motor drives the sprocket, chain and other components to operate, which, together with the No. 1 motor, drives the pressure roller to rotate, so that the fabric moves to the designated position. Then, the No. 2 cylinder controls the upper and lower clamping plates to clamp the fabric, and then rotates in the opposite direction to realize the fabric pulling and feeding. This process does not require manual intervention, which reduces the cost of manual operation and improves production efficiency. At the same time, through precise mechanical control, the fabric movement distance and tension are kept stable, avoiding the position deviation and uneven pulling problems of manual feeding, and ensuring the accuracy and consistency of fabric cutting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 A cutting device for processing ski jackets includes two side frames 1, with a pressure roller 2 rotatably connected between them. Straight grooves 3 are formed on the side walls of the two side frames 1. A cylinder 4 is installed on the inner wall of each side frame 1. A slider 5 is connected to the telescopic end of the cylinder 4. A cutting plate 6 is fixedly connected to one side of the slider 5. A motor 7 is connected to one end of the pressure roller 2. A lead screw 8 is rotatably connected between the two side frames 1, and a guide rod 9 is fixedly connected between them. A second motor 10 is installed on the outer wall of one side frame 1. A side plate 11 is bolted to one side of each side frame 1, and a feeding rack 12 is bolted to the other side of each side frame 1. The inner side is rotatably connected to the feeding roller 13, the inner side plate 11 is rotatably connected to the sprocket 14, the sprocket 14 is meshed with the chain 15, the outer surface of the chain 15 is snapped with the buckle 16, the top of the buckle 16 is fixedly connected to the bottom plate 17, the outer surface of the bottom plate 17 is fixedly connected to the lower clamping plate 18, the top surface of the bottom plate 17 is fixedly connected to the vertical rod 19, the top of the vertical rod 19 is fixedly connected to the gantry frame 20, the top surface of the gantry frame 20 is installed with the second cylinder 21, the telescopic end of the second cylinder 21 is connected to the upper clamping plate 22, the outer wall of the side plate 11 is installed with the third motor 23, the outer surface of the lead screw 8 is threadedly connected to the moving block 24, and the bottom end of the moving block 24 is installed with the circular cutter 25.

[0025] Specifically, sliders 5 are fixedly connected to both ends of the cutting board 6, and a groove is opened through the inner side of the side frame 1, with the sliders 5 slidably connected in the groove.

[0026] Specifically, the top of the cutting board 6 has a groove, in which a plastic strip 26 is embedded, and the plastic strip 26 contacts the circular cutter 25.

[0027] The advantage is that before cutting the fabric, the fabric is placed on the feeding roller 13. Since the fabric is usually rolled up, its head end can be pulled to position it between the cutting plate 6 and the pressure roller 2. By activating the two cylinders 4, the telescopic ends of the fabric are raised, which drives the two sliders 5. The two sliders 5 drive the cutting plate 6 to rise, so that the cutting plate 6 drives the fabric to contact the pressure roller 2, thus fixing the fabric and making it easier to cut the fabric later.

[0028] Specifically, the internal sliding connection guide rod 9 of the moving block 24, the output shaft connection screw 8 of the second motor 10, and the first motor 7 are installed on the inner side of one of the side frames 1.

[0029] The advantage is that when the second motor 10 is started, it drives the lead screw 8 to rotate. The lead screw 8 drives the moving block 24, which is threaded on its outer surface, to move. Under the guidance of the guide rod 9, the moving block 24 can drive the circular cutter 25 at its bottom to move. Since the circular cutter 25 contacts the plastic strip 26 and the fabric is on the upper surface of the cutting plate 6, the fabric can be cut after the circular cutter 25 moves.

[0030] Specifically, the side plate 11 has two sprockets 14 rotatably connected inside, and the output shaft of motor 23 is connected to the shaft of one of the sprockets 14.

[0031] The advantage is that after the fabric is cut once, the No. 3 motor 23 is started to drive one of the sprockets 14 to rotate. With the cooperation of the other sprocket 14, the chain 15 rotates, which causes the buckle 16 to move. The buckle 16 drives the base plate 17 to move. The base plate 17 drives the upper clamping plate 22 and the lower clamping plate 18 to move towards the cutting plate 6. The No. 1 motor 7 is started to drive the pressure roller 2 to rotate. Since the pressure roller 2 is in close contact with the fabric, the pressure roller 2 can drive the fabric to move towards the placement plate 27 under the action of friction. In this way, the fabric will extend from the cutting plate 6 and be between the upper clamping plate 22 and the lower clamping plate 18.

[0032] Specifically, the top surface of the side plate 11 is provided with a guide groove, and the guide groove is in sliding contact with the buckle 16. The top surface of the bottom plate 17 is connected to the gantry frame 20 by bolts. The outer surface of the vertical rod 19 is slidably connected to the clamping plate 22. The inner side of the side plate 11 is fixedly connected to the placement plate 27.

[0033] The advantage is that by activating cylinder 21, its telescopic end moves the upper clamping plate 22 downward. This allows the upper clamping plate 22, in conjunction with the lower clamping plate 18, to clamp the fabric. Then, motor 23 drives sprocket 14 to rotate in the opposite direction. This causes chain 15 to drive buckle 16, which in turn drives base plate 17 to reset, thus pulling the fabric. This process enables automatic fabric feeding and pulling. On the one hand, the fabric shifting can be completed without manual intervention, reducing labor costs and improving production efficiency. On the other hand, the precise control of the fabric's movement distance and tension through the mechanical structure avoids positional deviations or uneven pulling that may occur with manual feeding, ensuring the accuracy and consistency of fabric cutting.

[0034] In use, firstly, the rolled fabric is placed onto the feeding roller 13, and the fabric end is pulled to be positioned between the cutting plate 6 and the pressure roller 2. Then, the two cylinders 4 are activated, their extension ends rising to lift the slider 5 and the cutting plate 6, causing the fabric to contact the pressure roller 2 for fixation. Next, the second motor 10 is activated to rotate the lead screw 8. Guided by the guide rod 9, the moving block 24 moves the circular cutter 25, which, in conjunction with the plastic strip 26 on the top of the cutting plate 6, cuts the fabric. After one cut, the third motor 23 is activated to rotate the sprocket 14. The movement causes the chain 15, buckle 16, base plate 17, upper clamping plate 22, and lower clamping plate 18 to move toward the cutting plate 6. At the same time, the first motor 7 is started to drive the pressure roller 2 to rotate, using friction to make the fabric extend out of the cutting plate 6 and be positioned between the upper clamping plate 22 and the lower clamping plate 18. Then, the second cylinder 21 is started, and its telescopic end drives the upper clamping plate 22 to move downward, clamping the fabric with the lower clamping plate 18. Finally, the third motor 23 drives the sprocket 14 to rotate in the opposite direction, and the chain 15 drives the buckle 16 and base plate 17 to reset, realizing the automatic pulling and feeding of the fabric. The above steps are repeated for subsequent cutting.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
