Description

Technical Field

[0001] The utility model relates to the technical field of clothing production, in particular to a pre-leveling device for cloth used in clothing production before cutting. Background Art

[0002] Clothing production is a complex process, including design, cutting, sewing, sizing, packaging and other links. Clothing production first requires inspection and testing of fabrics and accessories to ensure that the materials meet production requirements. Then there is technical preparation, including the production of process sheets and samples, as well as the production of sample garments. Cutting is the process of cutting fabric into garment pieces according to design requirements. The fabric is pre-flattened before cutting to reduce wrinkles and folds during the fabric cutting process.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in the process of pre-leveling the cloth, it is necessary to adjust the height of the leveling roller according to the different thicknesses of the cloth. The operation of adjusting the height of the leveling roller in the pre-leveling device in the prior art is very cumbersome, and after adjusting the height, the pressure of the roller on the cloth is fixed, so the leveling effect is not good and wrinkles are prone to occur. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a pre-leveling device for fabrics used in clothing production before cutting.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a pre-leveling device for cloth cutting for clothing production, comprising a supporting leg and a leveling box fixed to the upper end of the supporting leg, the side wall of the leveling box being penetrated by a cloth inlet, the side wall of the leveling box being penetrated by a cloth outlet, the inner wall of the leveling box being close to the cloth inlet is provided with two cloth feeding rollers, the inner wall of the leveling box being close to the cloth outlet is provided with two cloth outlet rollers, the inner wall of the leveling box being provided with a slide groove, two symmetrically arranged sliders being slidably connected in the slide groove, each slider side wall being fixed with a U-shaped plate, the inner wall of the U-shaped plate being provided with a mounting groove, a leveling assembly being installed on the U-shaped plate, the leveling assembly comprising a mounting block slidably connected to the mounting groove, a leveling roller rotatably connected to the side wall of the mounting block, and a spring arranged in the mounting groove, the upper end of the spring being fixed to the top wall in the mounting groove, the lower end of the spring being fixed to the upper surface of the mounting block, and a driving assembly for driving the two sliders to move closer to each other is installed on the leveling box.

[0006] By adopting the above technical scheme, when it is necessary to pre-level the cloth before cutting, the staff transports the cloth into the leveling box through the cloth inlet and the cloth feed roller, and transmits the cloth out of the leveling box through the cloth outlet roller and the cloth outlet. The cloth in the leveling box is located between the two leveling rollers, and the two sliders are driven by the driving component to move closer to each other, so that the upper and lower leveling rollers move toward the cloth. The leveling rollers are pressed against the cloth under the elastic force of the spring, so as to level the cloth. It is convenient to adjust the height of the leveling roller according to the different thicknesses of the cloth, thereby improving the leveling effect of the cloth and reducing the probability of wrinkles on the cloth.

[0007] Furthermore, the driving assembly includes a double-headed screw that is installed through the leveling box and is rotatably connected, and a turntable fixed to the upper end of the double-headed screw. The lower end of the double-headed screw is rotatably connected to the bottom wall of the slide groove. The double-headed screw is provided with two sections of threads with equal pitch and opposite rotation directions. The two sliding blocks are respectively mounted on the double-headed screw and are threadedly connected to the two sections of threads on the double-headed screw.

[0008] By adopting the above technical solution, when it is necessary to drive the slider to move, the staff rotates the double-headed screw through the turntable. Since the double-headed screw is threadedly connected to the two sliders, and the two sliders are slidably connected to the slide grooves, the two sliders are moved closer to each other, which is convenient for pressing against the cloth to flatten the cloth.

[0009] Furthermore, a limit assembly for limiting the position of the turntable is installed on the turntable, and the limit assembly includes a threaded rod that is arranged on the turntable and threadedly connected, a clamping block that is rotatably connected to the lower end of the threaded rod, and an operating rod fixed to the upper end of the threaded rod.

[0010] By adopting the above technical solution, after adjusting the height of the two leveling rollers, the staff needs to tighten the clamping block through the operating lever so that the clamping block presses downward against the upper surface of the leveling box, thereby limiting the turntable and reducing the probability of displacement of the leveling roller due to the rotation of the turntable under the action of external force. In addition, the staff can also rotate the turntable through the operating lever, making it easier for the staff to rotate the turntable.

[0011] Furthermore, an anti-slip pad is fixed on the lower surface of the abutting block.

[0012] By adopting the above technical solution, the anti-slip pad is made of rubber material, and its surface has a large friction coefficient. The lower surface of the clamping block cooperates with the upper surface of the leveling box and presses against the anti-slip pad, which increases the friction between the clamping block and the leveling box, reduces the probability of the clamping block rotating, and enhances the limiting effect of the limit assembly on the turntable.

[0013] Furthermore, a movable groove is provided on the inner wall of the leveling box away from the slide groove, and a support block slidably connected to the movable groove is fixed on the side wall of each U-shaped plate away from the slider, and a guide rod slidably connected to the support block is provided through the support block, the upper end of the guide rod is fixed to the top wall of the movable groove, and the lower end of the guide rod is fixed to the bottom wall of the movable groove.

[0014] By adopting the above technical solution, the arrangement of the support blocks and the guide rods has a reinforcing and stabilizing effect on the U-shaped plate, thereby improving the stability of the U-shaped plate and the leveling assembly.

[0015] Furthermore, a fixing groove is provided on the side wall of the leveling roller, a heating wire is arranged in the fixing groove, and a sealing plate is fixed at the notch of the fixing groove by screws.

[0016] By adopting the above technical solution, the heating wire in the side wall of the leveling roller is used to heat the cloth passing through the leveling roller, thereby improving the leveling effect of the cloth.

[0017] Furthermore, heat dissipation openings are provided through the upper surface and the lower surface of the leveling box, and a heat dissipation fan is provided on the inner wall of each heat dissipation opening.

[0018] By adopting the above technical solution, two cooling fans cool down and dissipate heat on the upper and lower sides of the cloth passing through the leveling roller at the same time, which is beneficial to the rapid cooling of the cloth.

[0019] Furthermore, a filter screen is provided on the inner wall of each heat dissipation port.

[0020] By adopting the above technical solution, the filter screen plays a filtering and protective role on the heat dissipation opening, reducing the probability of external dust and debris entering the leveling box through the heat dissipation holes.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In the present application, when it is necessary to pre-level the fabric before cutting, the staff transports the fabric into the leveling box through the fabric inlet and the fabric feed roller, and the fabric is discharged from the leveling box through the fabric outlet roller and the fabric outlet. The fabric in the leveling box is located between the two leveling rollers, and the two sliders are driven to move toward each other by the driving assembly, so that the upper and lower leveling rollers move toward the fabric. The leveling rollers are pressed against the fabric under the elastic force of the spring, thereby leveling the fabric. It is convenient to adjust the height of the leveling roller according to the fabric of different thicknesses, thereby improving the leveling effect of the fabric and reducing the probability of wrinkles on the fabric.

[0023] 2. In this application, when the slider needs to be driven to move, the staff rotates the double-headed screw through the turntable. Since the double-headed screw is threadedly connected to the two sliders, and the two sliders are slidably connected to the slide groove, the two sliders move closer to each other, so as to press against the cloth to flatten the cloth;

[0024] 3. In the present application, after adjusting the height of the two leveling rollers, the staff needs to tighten the clamping block through the operating lever so that the clamping block presses downward against the upper surface of the leveling box, thereby limiting the turntable and reducing the probability of displacement of the leveling roller due to the rotation of the turntable under the action of external force. In addition, the staff can also rotate the turntable through the operating lever, making it easier for the staff to rotate the turntable. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1-4 As shown, an embodiment of the present application discloses a pre-leveling device for fabric before cutting for clothing production, including a support leg 1, a leveling box 2, a cloth feed roller 3, a cloth outlet roller 4, a slider 5, a U-shaped plate 6, a leveling component 7 and a driving component 8.

[0032] The supporting leg 1 is a vertically arranged rectangular rod-shaped structure, and a plurality of supporting legs 1 are provided. The leveling box 2 is a rectangular box structure, and the leveling box 2 is fixed to the upper ends of the plurality of supporting legs 1. A cloth inlet 21 is provided through the side wall of the leveling box 2, and a cloth outlet 22 is provided through the side wall of the leveling box 2 away from the cloth inlet 21, and a chute 23 is provided on the inner wall of the leveling box 2. The cloth feed roller 3 is arranged on the inner wall of the leveling box 2 near the cloth inlet 21, and two cloth feed rollers 3 are provided, and the cloth feed rollers 3 are used to transport the cloth. The cloth outlet roller 4 is arranged on the inner wall of the leveling box 2 near the cloth outlet 22, and two cloth outlet rollers 4 are provided, and the cloth outlet roller 4 is used to output the cloth. The slider 5 is a rectangular structure, and the slider 5 is arranged in the chute 23 and is slidably connected to the chute 23, and two sliders 5 are symmetrically provided. The U-shaped plate 6 is a plate-like structure with a U-shaped cross section. Two U-shaped plates 6 are provided. The two U-shaped plates 6 are respectively fixed on the side walls of the two sliders 5 . A mounting groove 61 is formed on the inner wall of each U-shaped plate 6 .

[0033] There are two groups of leveling components 7, which are respectively mounted on two U-shaped plates 6, and each group of leveling components 7 includes a mounting block 71, a leveling roller 72, and a spring 73. The mounting block 71 is a rectangular parallelepiped structure, and the mounting block 71 is slidably connected in the mounting groove 61. The leveling roller 72 is a round roller structure, and the leveling roller 72 is rotatably connected to the side wall of the mounting block 71. The spring 73 is arranged in the mounting groove 61, and the upper end of the spring 73 is fixed to the top wall of the mounting groove 61, and the lower end of the spring 73 is fixed to the upper surface of the mounting block 71.

[0034] The driving assembly 8 is installed on the leveling box 2, and is used to drive the two sliders 5 to move closer to each other. The driving assembly 8 includes a double-headed screw 81 and a turntable 82. The double-headed screw 81 is a vertically arranged rod-shaped structure. The double-headed screw 81 is arranged on the leveling box 2 and is rotatably connected. The lower end of the double-headed screw 81 is rotatably connected to the inner bottom wall of the slide groove 23. The double-headed screw 81 is provided with two sections of threads with equal pitch and opposite rotation. The two sliders 5 are respectively sleeved on the double-headed screw 81 and are threadedly connected with the two sections of threads on the double-headed screw 81. The turntable 82 is a disc-shaped structure. The turntable 82 is fixed to the upper end of the double-headed screw 81, and the axis of the turntable 82 coincides with the axis of the double-headed screw 81.

[0035] When it is necessary to pre-level the cloth before cutting, the staff transports the cloth into the leveling box 2 through the cloth inlet 21 and the cloth feed roller 3, and passes through the cloth outlet roller 4 and the cloth outlet 22 to be discharged from the leveling box 2. The cloth in the leveling box 2 is located between the two leveling rollers 72, and the double-headed screw 81 is rotated by the turntable 82. Since the double-headed screw 81 is threadedly connected to the two sliders 5, and the two sliders 5 are slidingly connected to the slide groove 23, the two sliders 5 are moved closer to each other, so that the upper and lower leveling rollers 72 move toward the cloth. The leveling roller 72 is pressed against the cloth under the elastic force of the spring 73, thereby leveling the cloth. It is convenient to adjust the height of the leveling roller 72 according to the cloth of different thicknesses, thereby improving the leveling effect on the cloth and reducing the probability of wrinkles on the cloth.

[0036] In order to reduce the probability of the turntable 82 rotating under the action of external force, a limit assembly 9 is installed on the turntable 82 for limiting the turntable 82. The limit assembly 9 includes a threaded rod 91, a clamping block 92 and an operating rod 93. The threaded rod 91 is a vertically arranged rod-shaped structure, which is penetrated and arranged on the turntable 82 and threadedly connected. The clamping block 92 is a round block-shaped structure, which is rotatably connected to the lower end of the threaded rod 91, and the axis of the clamping block 92 coincides with the axis of the threaded rod 91. The operating rod 93 is a vertically arranged round rod-shaped structure, which is fixed to the upper end of the threaded rod 91, and the axis of the operating rod 93 coincides with the axis of the threaded rod 91. After adjusting the height of the two leveling rollers 72, the staff needs to tighten the clamping block 92 through the operating rod 93 so that the clamping block 92 presses downward against the upper surface of the leveling box 2, thereby limiting the turntable 82, thereby reducing the probability of displacement of the leveling roller 72 due to the rotation of the turntable 82 under the action of external force. In addition, the staff can also rotate the turntable 82 through the operating rod 93, making it easier for the staff to rotate the turntable 82.

[0037] In order to enhance the limiting effect of the limiting component 9 on the turntable 82, an anti-skid pad 10 is fixed to the lower surface of the clamping block 92. The anti-skid pad 10 is made of rubber material and its surface has a large friction coefficient. The lower surface of the clamping block 92 cooperates with the upper surface of the leveling box 2 and presses against the anti-skid pad 10, which increases the friction between the clamping block 92 and the leveling box 2 and reduces the probability of the clamping block 92 rotating, thereby enhancing the limiting effect of the limiting component 9 on the turntable 82.

[0038] In order to improve the stability of the U-shaped plate 6 and the leveling assembly 7, a movable groove 24 is opened on the inner wall of the leveling box 2 away from the sliding groove 23, and each U-shaped plate 6 is fixed with a support block 11 slidingly connected to the movable groove 24 on the side wall away from the slider 5. A guide rod 12 slidingly connected to the support block 11 is provided through the support block 11, and the upper end of the guide rod 12 is fixed to the inner top wall of the movable groove 24, and the lower end of the guide rod 12 is fixed to the inner bottom wall of the movable groove 24. The setting of the support block 11 and the guide rod 12 reinforces and stabilizes the U-shaped plate 6, thereby improving the stability of the U-shaped plate 6 and the leveling assembly 7.

[0039] In order to improve the leveling effect on the cloth, a fixing groove 721 is opened on the side wall of the leveling roller 72, a heating wire 13 is arranged in the fixing groove 721, and a sealing plate 14 is fixed at the notch of the fixing groove 721 by screws. The heating wire 13 in the side wall of the leveling roller 72 is used to heat the cloth passing through the leveling roller 72, thereby improving the leveling effect on the cloth.

[0040] In order to quickly cool the cloth, heat dissipation holes 25 are opened through the upper surface and the lower surface of the leveling box 2. A cooling fan 15 is provided on the inner wall of each heat dissipation hole 25. The two cooling fans 15 cool down and dissipate heat on the upper and lower sides of the cloth passing through the leveling roller 72 at the same time, which is conducive to the rapid cooling of the cloth.

[0041] In order to protect the heat dissipation openings 25 , a filter screen 16 is provided on the inner wall of each heat dissipation opening 25 . The filter screen 16 plays a filtering and protective role on the heat dissipation openings 25 , thereby reducing the probability of external dust and debris entering the leveling box 2 through the heat dissipation holes.

[0042] The use principle of a pre-leveling device for fabric cutting for clothing production in the present embodiment is as follows: when it is necessary to pre-level the fabric before cutting, the staff transports the fabric into the leveling box 2 through the fabric inlet 21 and the fabric feed roller 3, and the fabric is discharged from the leveling box 2 through the fabric outlet roller 4 and the fabric outlet 22. The fabric in the leveling box 2 is located between the two leveling rollers 72, and the double-headed screw 81 is rotated by the turntable 82. Since the double-headed screw 81 is threadedly connected to the two sliders 5, and the two sliders 5 are slidably connected to the slide groove 23, the two sliders 5 are moved closer to each other, so that the upper and lower leveling rollers 72 move toward the fabric. The leveling roller 72 is pressed against the fabric under the elastic force of the spring 73, thereby leveling the fabric, and it is convenient to adjust the height of the leveling roller 72 according to fabrics of different thicknesses, thereby improving the leveling effect on the fabric and reducing the probability of wrinkles on the fabric.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
