Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric processing technology, and in particular to an underwear fabric cutting device. Background Technology
[0002] In the garment production process, fabrics are usually cut in a concentrated manner to facilitate subsequent processing. When producing small areas of fabric, such as underwear, to save processing time, workers usually stack the pre-cut fabrics and then move the stacked fabrics to the cutting equipment. The cutting equipment cuts the fabrics into semi-finished products of a predetermined shape, and finally the workers sew the semi-finished products together to obtain the finished underwear.
[0003] During the transfer and placement of stacked fabrics, wrinkles are inevitable, and the degree of wrinkling varies among different layers. This can lead to deviations in the shape of the cut fabric from the same batch, affecting processing accuracy. Therefore, there is a need for fabric cutting equipment that can reduce the impact of wrinkles on cutting accuracy, thereby improving the processing precision of semi-finished products.

[0032] The present invention will be described in detail below with reference to specific embodiments.
[0033] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.
[0034] like Figures 1 to 10 As shown, this utility model provides an underwear fabric cutting device, including a frame 1. The frame 1 is equipped with multiple flattening mechanisms. Each flattening mechanism includes a transfer component 2 and a roller pressing component 3. The roller pressing component 3 is used to flatten the fabric, and the transfer component 2 is used to drive the roller pressing component 3 to move on the frame 1. The roller pressing component 3 includes a support rod 30, a cantilever 31 and a pressing roller 32. The transfer component 2 includes a transverse drive, a slide 23 and a lifting drive 24. The transverse drive is installed on the frame 1 and is used to drive the slide 23 to slide on the frame 1. The lifting drive 24 is installed on the slide 23 and is used to lift the support rod 30. The support rod 30 is equipped with a cantilever 31, and the bottom of the cantilever 31 is provided with a pressing roller 32. The central axis of the pressing roller 32 is perpendicular to the moving direction of the slide 23.
[0035] With the above design, when it is necessary to flatten the fabric on the frame 1, the transverse drive unit moves the pressing roller 32 above the fabric by driving the slide 23. Then, the lifting drive unit 24 controls the support rod 30 to descend until the pressing roller 32 presses down on the fabric. Then, the transverse drive unit controls the slide 23 to move back and forth, thereby causing the pressing roller 32 to move back and forth. The pressing roller 32 is used to press the stacked fabric and flatten the wrinkles.
[0036] In this embodiment, a set of transverse drive components are respectively provided at both ends of the frame 1. Each set of transverse drive components is connected to two sets of slides 23. Each pair of slides 23 is equipped with a set of roller pressing components 3. The slides 23 are also provided with clamping drive components 25 and clamping plates 26. The clamping drive components 25 are located directly above the clamping plates 26. The transverse drive components include a transverse motor 20 and a synchronous belt 21. The transverse motor 20 is installed on the frame 1. The transverse motor 20 can drive the synchronous belt 21 to rotate. The clamping drive components 25 can clamp the synchronous belt 21 on the clamping plates 26.
[0037] With the above design, during the pressing operation, the clamping drive components 25 on both sets of slides 23 are activated simultaneously, connecting the synchronous belt 21 to the two sets of slides 23. With the activation of the transverse motor 20, a single synchronous belt 21 can simultaneously drive both sets of slides 23 to slide on the frame 1. The pressing rollers 32 on the two sets of slides 23 reciprocate on the frame 1 under the drive of the transverse motor 20. Given that the lifting drive component 24 has determined the lifting height, the reciprocating pressing rollers 32 can repeatedly flatten the fabric, reducing wrinkles and protrusions on the fabric. After a certain period of flattening, the equipment changes its drive mode, and the operation of the pressure rollers 32 changes from flattening to pressing: the transverse drive first drives both sets of pressure rollers 32 to approach one side of the fabric edge, then the clamping drive 25 corresponding to the pressure roller 32 closest to the fabric edge releases, so that the pressure roller 32 is no longer driven by the transverse motor 20; since the second set of slides 23 is still connected to the synchronous belt 21, the transverse motor 20 can continue to drive the other set of pressure rollers 32 to slide on the frame 1; the second set of pressure rollers 32 then moves to the other side of the fabric edge, and then the two sets of pressure rollers 32 press down respectively, so that the two sets of pressure rollers 32 press the fabric on both sides respectively, and then the clamping drive 25 corresponding to the two sets of pressure rollers 32 clamps at the same time. With the relative positioning of the synchronous belt 21 and the resistance of the transverse motor 20, the positions of the two sets of pressure rollers 32 are fixed, avoiding the fabric from shifting during the cutting process and improving the cutting accuracy.
[0038] In this embodiment, the cantilever 31 includes a fixed base 310, a swing arm 311, and a suspension rope 312. The cantilever 31 is fixedly installed on the support rod 30. One end of the swing arm 311 is hinged to the fixed base 310, and the other end of the swing arm 311 is connected to the pressure roller 32. One end of the suspension rope 312 is connected to the swing arm 311, and the other end of the suspension rope 312 is installed on the fixed base 310 through a tension sensor.
[0039] Through the above design, the swing arm 311 can swing on the fixed base 310. By changing the connection position between the suspension rope 312 and the swing arm 311, the suspension rope 312 can adjust the height of the pressure roller 32, while keeping the swing arm 311 in a bent state, allowing it a certain amount of swing space. When the lifting drive 24 drives the pressure roller 32 to descend, the pressure roller 32 stops descending after contacting the stacked fabric, avoiding excessive compression and damage to the lifting drive 24. At the same time, when the pressure roller 32 contacts the fabric, the taut suspension rope 312 relaxes, and the tension sensor connected to the suspension rope 312 detects the data change and quickly sends a stop signal to the lifting drive 24, stopping the lifting drive 24 from driving. As the lateral drive moves, the pressure roller 32, which falls on the fabric, rolls back and forth on the fabric, making the fabric flatter and firmer.
[0040] In this embodiment, a scale plate 41 is provided on the frame 1, and a positioning camera 22 is provided on the support rod 30, with the positioning camera 22 located directly above the scale plate 41.
[0041] With the above design, the scale plate 41 on the frame 1 can easily position the pressure roller 32, and the positioning camera 22 on the support rod 30 can be accurately positioned by the information on the scale plate 41, making it convenient for the control console to record the position of the pressure roller 32.
[0042] When the pressure roller 32 is repeatedly pressed, when the pressure roller 32 leaves the fabric, it loses the support of the fabric and falls again. The falling pressure roller 32 will cause the suspension rope 312 to tighten again. The tension sensor detects the data change, and at the same time, the positioning camera 22 records the position of the scale plate 41 when the tension sensor changes, so that the equipment can locate the position of the pressure roller 32.
[0043] In this embodiment, a cutting platform 4 is provided on the frame 1, and multiple sets of positioning stripes 40 are provided on the cutting platform 4.
[0044] Through the above design scheme, the positioning stripes 40 on the cutting platform 4 allow the staff to intuitively understand the position of the fabric, making it convenient for the workers to place the fabric in the most central position possible so that the machine can cut the fabric in the subsequent process.
[0045] It should be noted that the staff needs to input the desired shape for cutting into the main control panel, and then input the length, width, material, quantity of the fabric, and the approximate position of the fabric on the cutting platform 4 into the main control panel. The main control panel can then automatically perform the pressing and cutting work.
[0046] In this embodiment, a cutting assembly 5 is provided on the frame 1. The cutting assembly 5 includes a longitudinal drive member 50, a longitudinal slide 51, a transverse drive member 57, a transverse slide 52, a lifting drive member 53, a rotating drive member 54, a cutting blade 55, and a pressure plate 56. The longitudinal drive member 50 is mounted on the frame 1 and is used to drive the longitudinal slide 51 to move on the frame 1. The direction of movement of the longitudinal slide 51 is parallel to the central axis of the pressure roller 32. The transverse drive member 57 is mounted on the longitudinal slide 51 and is used to drive the transverse slide 52 to slide on the longitudinal slide 51. The direction of movement of the transverse slide 52 is perpendicular to the central axis of the pressure roller 32. The lifting drive member 53 is mounted on the transverse slide 52 and is used to drive the rotating drive member 54 to move closer to or away from the frame 1. A cutting blade 55 is mounted at the bottom of the rotating drive member 54, and a pressure plate 56 is provided at the bottom of the cutting blade 55.
[0047] With the above design scheme, under the joint drive of the longitudinal drive member 50, the transverse drive member 57 and the lifting drive member 53, the cutting blade 55 can go to any position on the cutting platform 4 to cut the fabric placed on the cutting table. In this embodiment, the cutting blade 55 can be a laser cutter or an ultrasonic cutter. When the cutting blade 55 is an ultrasonic cutter, the rotary drive member 54 can be used to control the blade of the ultrasonic cutter to face the forward direction of the cutting blade 55. Since the longitudinal drive member 50, the longitudinal slide 51, the transverse drive member 57, the transverse slide 52, the lifting drive member 53, the rotary drive member 54, the cutting blade 55 and the pressure plate 56 are existing technologies and are not the improvement points of this utility model, they are not described in detail in this embodiment.
[0048] In this embodiment, the pressure plate 56 is provided with multiple sets of light rods, the cutting blade 55 is provided with a detachable mounting bracket, the light rods can slide on the mounting bracket, and a buffer elastic element is sleeved on the light rod. One end of the buffer elastic element abuts against the pressure plate 56, and the other end of the buffer elastic element abuts against the mounting bracket.
[0049] In this embodiment, a U-shaped groove is provided at the center of the pressure plate 56, and both the U-shaped groove and the edge of the pressure plate 56 are provided with raised edges.
[0050] With the above design scheme, when the cutting operation is carried out, the lifting drive 53 controls the cutting blade 55 to descend, so that the pressure plate 56 presses down on the edge of the part to be cut, preventing the fabric from curling up during the cutting process and affecting the cutting effect. Since the setting of the pressure plate 56 is the prior art and is not the improvement point of this utility model, it is not described in detail in this embodiment.
[0051] In this embodiment, a straightening beam 58 is provided on the longitudinal carriage 51, and multiple sets of traction ropes 59 are provided on the straightening beam 58. One end of the traction rope 59 is fixedly connected to the straightening beam 58, and the other end of the traction rope 59 is connected to the longitudinal carriage 51; the straightening beam 58 has an H-shaped cross section.
[0052] With the above design scheme, the straightening beam 58 can pull the longitudinal carriage 51 with the traction rope 59, reduce the deformation of the longitudinal carriage 51 caused by its own weight, make the longitudinal carriage 51 as straight as possible, and reduce cutting errors.
[0053] In this embodiment, limit switches are provided on the frame 1, slide 23, longitudinal slide 51 and transverse slide 52 to prevent collisions between different components during movement.
[0054] In this embodiment, the lifting drive 24, clamping drive 25 and lifting drive 53 are all linear modules; the transverse motor 20, longitudinal drive 50 and lateral drive 57 are all servo motors.
[0055] In this embodiment, both the hoisting rope 312 and the traction rope 59 are made of steel wire.
[0056] The underwear fabric cutting equipment provided by this utility model, compared with the prior art, has a pressing roller 32 repeatedly pressing on the fabric under the drive of the transverse drive component before the cutting operation. It flattens the stacked materials by its own weight, making the interior of the stacked fabric flatter and closer together, ensuring that the semi-finished products cut in the same batch are more similar in precision and reducing errors.
[0057] Where there is no conflict, the above embodiments and features can be combined with each other.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
