Description

Technical Field

[0001] The invention relates to the field of cutting equipment, in particular to a pre-processing equipment for garment processing. Background Art

[0002] In order to improve the quality of clothing during garment processing, the fabric needs to be loosened and cut before sewing, which is directly related to the quality and appearance of the finished garment. Fabric is usually in the form of rolls when it leaves the factory, so before making clothes, the fabric rolls need to be rolled out. After rolling out, the fabric needs to be cut from the fabric roll and then cut to obtain the pieces required for making clothes.

[0003] If the spread-out fabric is not completely flattened, for example, wrinkles or curls appear, it can easily lead to adverse consequences such as inaccurate size of the cut pieces and shapes that do not meet design requirements, which in turn affects the subsequent sewing process and the quality of the final product. Summary of the invention

[0004] The object of the present invention is to provide a pre-treatment device for garment processing in view of the above problems, which can reduce the phenomenon that the fabric is not completely flattened.

[0005] To achieve the above purpose, the technical solution adopted in this application is: a pre-processing equipment for garment processing, including a cutting mechanism for cutting cloth, a base arranged on one side of the cutting mechanism, a workbench arranged on the upper end of the base, a mounting frame moving along the line connecting the base arranged above the workbench, rotating parts arranged at intervals on the mounting frame, the rotating parts rotating around their transverse axes, an elastic retractable part arranged along the radial direction on the outer side wall of the rotating part, a flattening part arranged at the outer end of the elastic retractable part, and the cloth is flattened by the flattening part to avoid the undesirable phenomenon that the cut pieces after cutting appear inaccurate size and shape not meeting the requirements due to wrinkles, etc. In order to improve the level of automation, it also includes a traction mechanism for traction cloth moving from one end of the workbench to the other end, and the cloth is spread on the workbench by the traction mechanism to reduce the workload of the staff.

[0006] Furthermore, in order not to interfere with the installation and operation of the flattening part, the traction mechanism includes traction seats disposed on both sides of the workbench, the traction seats move in the lateral direction, and a clamping mechanism is provided on the traction seats.

[0007] Furthermore, the elastic expansion part and the flattening part are detachably connected, and the flattening part can press the cloth to ensure the flatness of the cloth and avoid the cloth moving during the cutting process. This can ensure that the edges of the cut pieces are neat and the shapes are accurate, thereby improving the quality of subsequent sewing.

[0008] Furthermore, in order to automatically remove the flattening part from the elastic telescopic part and fix it on the workbench, at least one end of the flattening part in the length direction extends out of the elastic telescopic part, and a bracket that moves vertically is provided on the workbench. The bracket is rotatably connected to one end of the clamping plate through an elastic element, and a baffle that limits the upward rotation of the clamping plate is provided on the bracket above the clamping plate. One end of the clamping plate extends out of the baffle and extends toward the inside of the workbench.

[0009] Furthermore, the elastic telescopic portion and the flattening portion are provided with matching positioning grooves and positioning keys to ensure that the flattening portion does not move during the contact process with the cloth.

[0010] Furthermore, the cutting mechanism comprises a sliding seat that moves laterally, a lifting seat that moves vertically is arranged on the sliding seat, and a cutting knife is installed on the lifting seat.

[0011] Furthermore, the workbench moves in a vertical direction to adapt to fabrics of different thicknesses, to adapt to the working mode of cutting multiple layers of fabrics at the same time, and to ensure that the flattening part can work normally.

[0012] Furthermore, in order to ensure the transfer of the cloth, a feeding mechanism is provided on one side of the base; the feeding mechanism includes a feeding roller group and a loading platform arranged in a transverse direction, the feeding roller group includes two feeding rollers arranged in a vertical direction, the loading platform is located at the proximal end of the workbench, and the loading platform is offset from the working path of the traction mechanism.

[0013] Furthermore, sliding tables are provided on both sides of the loading platform, and the sliding tables move along the working direction of the traction mechanism. The sliding tables temporarily support the edge of the cloth to prevent the edge of the cloth from falling due to long-term lack of support, thereby causing the traction mechanism to be unable to clamp the cloth.

[0014] Furthermore, the sliding table is driven by a traction mechanism to reduce the number of driving mechanisms.

[0015] The beneficial effects of the present application are as follows: the fabric is spread on the workbench. Then the cutting mechanism starts to work to cut the spread fabric from the fabric roll. The flattening part rotates with the rotating part and contacts the fabric to stretch and spread the fabric outward. This ensures that the spread fabric will not have wrinkles, warping, etc., thereby avoiding undesirable phenomena such as inaccurate size and shape of the cut pieces after cutting due to wrinkles and other problems, thereby improving the overall efficiency and product quality of clothing manufacturing.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0024] Embodiment 1, as Figure 1-Figure 3 As shown, the specific structure of this embodiment is a pre-processing device for garment processing, including a cutting mechanism for cutting fabrics and a base 1 arranged at intervals, a workbench 2 is arranged on the upper end of the base 1, and a hydraulic cylinder, an electric push rod, etc. are arranged in the base 1 to push the workbench 2 to move vertically. A mounting frame 3 and a support beam 16 are arranged above the workbench 2.

[0025] The bases 1 are arranged at intervals along the width direction of the workbench 2. This embodiment takes two workbenches 2 as an example. For the convenience of description, the two workbenches are named workbench No. 1 and workbench No. 2 respectively. The position of each workbench corresponds to a cloth roll unwinding device. The mounting frame 3 is arranged on the guide rail and moves along the connecting line between the bases 1 under the drive of an electric push rod, a linear module, a ball screw, etc. A rotating part 4 is arranged at intervals at the lower end of the mounting frame 3. When the mounting frame 3 is located directly above the workbench 2, the two rotating parts 4 are symmetrically arranged along the axis of the length direction of the workbench. The rotating part 4 is arranged along the length direction of the workbench 2. Both ends of the rotating part 4 are installed on the bearing seat at the lower end of the mounting frame 3. The rotating part 4 rotates around its transverse axis when driven by a motor, etc. An elastic telescopic part 5 is arranged on the outer wall of the rotating part 4 along its radial direction, and the elastic telescopic part 5 can be arranged in a circular array around the rotating part 4. The elastic telescopic part 5 can be an elastic telescopic rod, etc. In this embodiment, the elastic telescopic part 5 includes a fixed part and a movable part. The fixed part is fixedly arranged on the side wall of the rotating part 4. A receiving groove is arranged at the outer end of the fixed part, and a circle of retaining edges is arranged at the opening of the receiving groove. The movable part is provided with an extension part at one end of the fixed part. The outer diameter of the extension part is larger than the inner diameter of the retaining edge, so that the movable part cannot be separated from the fixed part, and the maximum distance that the elastic telescopic part 5 can be stretched is limited. The movable part extends into the receiving groove at one end of the extension part, and the receiving groove and the movable part are connected by a spring arranged along the radial direction of the rotating part 4. The other end of the movable part extends out of the receiving groove and is connected to the flattening part 6, and the contact surface of the flattening part 6 with the cloth is set to be arc-shaped.

[0026] The traction mechanism disposed above the workbench 2 is used to pull the cloth from the proximal side of the cutting mechanism to the distal side of the cutting mechanism. The traction mechanism includes traction seats 7 disposed on both sides of the length direction of the workbench. The traction seats 7 are disposed on guide rails disposed along the length direction of the workbench 2. Both ends of the guide rails are fixed to the lower ends of the support beams 16. The traction seat 7 moves along the length direction of the workbench 2 under the drive of existing linear drive mechanisms such as electric push rods and linear modules. The traction seat 7 is provided with a clamping mechanism 8 on one side of the workbench. The clamping mechanism 8 can adopt pneumatic clamping fingers in the prior art.

[0027] The cutting mechanism includes a sliding seat 13 that moves along the width direction of the workbench 2. For this purpose, the sliding seat 13 is arranged on a guide beam, and the guide beam is fixedly arranged on a support beam 16 and arranged along the width direction of the workbench. The sliding seat 13 moves along the width direction of the workbench 2 under the push of a linear drive mechanism such as an electric push rod and a linear module. A lifting drive mechanism such as an electric push rod is arranged inside the sliding seat 13. The piston rod of the lifting drive mechanism is connected to the lifting seat 14. A cutting knife 15 is installed on the lifting seat 14. At the same time, the lifting seat 14 can be installed with a lateral drive mechanism as needed to push the cutting knife 15 to move to one side of the workbench 2. The cutting knife 15 is close to the workbench 2 or located above the workbench 2 when cutting the cloth.

[0028] Specific working process: The clamping mechanism 8 is located on one side of the cutting mechanism. The clamping mechanism 8 clamps the edges of the cloth on both sides and pulls the cloth to move along the length direction of the workbench 2 to unfold the cloth and place it on the No. 1 workbench. At this time, according to the actual situation, you can choose to cut or lay it flat first. This embodiment will be described by taking laying it flat first as an example.

[0029] Before the cloth is unfolded, the rotating part 4 is in a non-vertical downward state. After the cloth is unfolded, the rotating part 4 starts to rotate, so that the elastic and retractable part 5 located on the inner side of the workbench 2 gradually rotates to the bottom of the rotating part 4. During the rotation process, the flattening part 6 has already contacted the cloth before the elastic and retractable part 5 is completely rotated to the bottom of the rotating part 4, thereby flattening the cloth from the inside to the outside, ensuring that the cloth is flat and avoiding wrinkles, warping, etc. As the rotating part 4 rotates, the length of the elastic and retractable part 5 is compressed and shortened, which not only ensures the pressure on the cloth, but also does not interfere with the rotation of the rotating part 4.

[0030] When one elastic telescopic part 5 rotates to the position directly below the rotating part 4, the cloth is fixed between the flattening part 6 and the workbench 2. At this time, the cutting knife 15 moves to one side of the cloth and then moves along the width direction of the workbench 2 to complete the cutting of the cloth. After the cutting is completed, the cutting knife 15 is reset, and then the clamping mechanism 8 releases the cloth and resets. By lowering the workbench 2, multiple layers of cloth can be stacked.

[0031] After the cloth on the No. 1 workbench is cut from the cloth roll, the mounting frame moves with the rotating part 4 etc. to the top of the No. 2 workbench to cut the cloth from the cloth roll again, and the staff performs secondary cutting on the material on the No. 1 workbench to obtain cut pieces.

[0032] Embodiment 2, as Figure 1-Figure 5 As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1, but in this embodiment, the elastic telescopic part 5 and the flattening part 6 are detachably connected, and the connection method can be magnetic connection, snap connection, etc.

[0033] At least one end of the flattened portion 6 in the length direction extends out of the elastic telescopic portion 5. In this embodiment, both ends of the flattened portion 6 in the length direction extend out of the elastic telescopic portion 5. The elastic telescopic portion 5 and the flattened portion 6 are provided with matching positioning grooves and positioning keys 12, and the positioning keys 12 are arranged along the radial direction of the rotating portion 4.

[0034] The four corners of the workbench 2 are provided with avoidance spaces, and a vertical driving mechanism such as a cylinder is installed at the lower end of the avoidance spaces. The piston rod of the vertical driving mechanism moves vertically and is connected to the bracket 9. The bracket 9 is rotatably connected to one end of the clamping plate 10 through elastic elements such as torsion springs and elastic hinges. A baffle 11 is provided on the bracket 9 above the clamping plate 10. In the absence of external force, the clamping plate 10 maintains a horizontal state, and a partial area of ​​the upper end of the clamping plate 10 contacts the lower end of the baffle 11. In this state, the clamping plate 10 partially extends out of the baffle and extends toward the inner side of the workbench 2 along the width direction of the workbench 2. When the cloth is placed on the workbench 2, the cloth does not completely cover the baffle 11.

[0035] During specific operation: when the flattening portion 6 is located directly below the rotating portion 4, the bracket 9 drives the pressing plate 10 to rise. During the rising process, the pressing plate 10 is affected by the cloth and the flattening portion 6 and rotates downward so as to be able to move above the flattening portion 6. Subsequently, the pressing plate 10 moves downward, and due to the obstruction of the baffle 11, the pressing plate 10 cannot rotate upward. In this way, the pressing plate 10 drives the flattening portion 6 to move downward together, so that the flattening portion 6 is separated from the elastic telescopic portion 5, thereby fixing the cloth at the upper end of the workbench 2, providing convenience for subsequent cutting operations. In the above process, the workbench can cooperate to descend to ensure that the flattening portion 6 can be smoothly separated from the elastic telescopic portion 5. Once the flattening portion 6 is separated from the elastic telescopic portion 5, the elastic telescopic portion 5 will be rotated out from the bottom of the rotating portion 4, and the staff can install a new flattening portion 6 on the elastic telescopic portion 5.

[0036] Embodiment 3, as Figure 1 , Figure 6As shown, other structures and working processes of this embodiment are the same as those of Embodiment 1, but in this embodiment, a feeding mechanism is provided on one side of the base 1; the feeding mechanism includes a feeding roller group and a loading platform 17, the feeding roller group and the loading platform 17 are arranged at intervals along the length direction of the workbench 2, the loading platform 17 is located at the proximal end of the workbench 2, the feeding roller group includes two feeding rollers 18 arranged in a vertical arrangement, at least one of which rotates under the drive of a motor, the feeding roller 18 is arranged along the width direction of the workbench 2, the loading platform 17 is staggered from the working path of the traction mechanism, and sliding platforms 19 are provided on both sides of the loading platform 17, the upper end surfaces of the loading platform 17 and the sliding platform 19 are adapted to the height of the clamping area of ​​the clamping mechanism 8, and the two sides of the cloth in the width direction are supported by the sliding platform 19 to prevent the edge of the cloth from falling and causing the clamping mechanism 8 to be unable to clamp the cloth. However, in order to ensure that the clamping mechanism 8 can clamp the cloth, the sliding table 19 moves along the working direction of the traction mechanism so that when the clamping mechanism moves to both sides of the loading platform, the sliding table will not interfere with the clamping mechanism. The sliding table can be driven by a cylinder, an electric push rod, etc., but in order to reduce the number of driving mechanisms, the sliding table 19 is driven by the traction mechanism, and for this purpose, the side wall of the sliding table 19 and the side wall of the loading platform 17 are key grooves, and the sliding table 19 is located on the moving path of the traction seat 7. When the traction seat 7 contacts the sliding table 19, the traction seat 7 can drive the sliding table 19 to move to the far end of the workbench 2. At this time, the clamping mechanism 8 just takes over the position of the sliding table 19 so that the cloth is located between the two clamping fingers.

[0037] Specific working process: the cloth sent out by the cloth roll unwinding device first passes between the two feeding rollers 18, and the two feeding rollers 18 press the two ends of the cloth respectively. As the feeding rollers 18 rotate, the cloth is sent to the upper end of the loading platform 17. At this time, the side of the cloth at one end of the workbench 2 is supported by the sliding platform 19. When the traction seat 7 moves to the sliding platform 19, the side wall of the traction seat 7 presses against the side wall of the sliding platform 19, thereby pushing the sliding platform 19 to move to the far end of the workbench 2. At this time, the clamping mechanism 8 fills the position to ensure that the clamping mechanism 8 can clamp the edge of the cloth.

[0038] After the clamping mechanism 8 clamps the fabric, the clamping mechanism 8 moves with the traction seat 7 toward the far end of the loading platform 17 to unfold the fabric and place it on the upper end of the workbench 2. At this time, the sliding platform 19 can be reset by assisting with a spring or the like, that is, a spring in the same direction as the length direction of the workbench 2 is provided in the groove connecting the sliding platform 19 and the loading platform 17. When the sliding platform 19 moves away from the workbench 2, the spring is compressed. When the traction seat 7 moves away from the loading platform 17, the spring is extended to reset the sliding platform 19. Alternatively, the groove connecting the sliding platform 19 and the loading platform 17 is closed at both ends in the length direction of the workbench 2, and the sliding platform 19 is magnetically connected to the traction seat 7, so that the sliding platform 19 is driven to move by the traction seat 7 until the sliding platform 19 is restricted by the end surface of the groove and stops.
