Description

Technical Field

[0001] This invention relates to the technical field of garment production, specifically a garment design, production, shaping, and pressing equipment. Background Technology

[0002] As is well known, clothing fabrics are made of fibers (cotton, wool, silk, linen, chemical fibers and blends) interwoven with yarns. The fiber molecules are arranged in a disordered manner and are easily deformed and wrinkled under external force. Therefore, the shaping and pressing process is used to rearrange the fabric fibers and solidify their shape under the dual action of heat and moisture. The core function is to eliminate wrinkles, stabilize the size, create a three-dimensional shape and improve the stiffness.

[0003] The shaping and pressing equipment includes both overall garment pressing and shaping and partial garment pressing and shaping. For partial garment pressing and shaping, such as collars, sleeves, and trouser creases, different moving mold components (which work with the fixed mold components to provide heating, steam, and pressing force) and fixed mold components (which are arc-shaped molds that mimic the curvature of a part of the garment, such as the sleeve, to support and position the sleeve to be pressed and shaped) can be changed depending on the pressing and shaping location.

[0004] Its workflow includes (taking the sleeves of a garment as an example):

[0005] During the material placement and positioning stage, the garment sleeves are placed onto the lower mold shaping seat of the mold-setting component. The seam allowance and grain are adjusted to ensure that the sleeves completely conform to the curvature of the lower mold shaping seat, ensuring accurate positioning and avoiding shaping deviation due to offset.

[0006] During the pressing and softening phase, the operator triggers the equipment by pressing a switch. The drive mechanism then smoothly lowers the upper pressing head in the moving mold assembly, closing it with the lower shaping seat. Simultaneously, the heating element inside the upper pressing head begins heating, raising the temperature to a preset value (110–200℃ depending on the fabric). If steam mode is used, steam is introduced into the upper pressing head through the steam pipe, penetrating the fabric to quickly soften the fibers, releasing the internal stress generated during weaving and sewing, thus creating conditions for shaping.

[0007] During the pressure setting stage, the upper mold pressing head and the lower mold setting seat remain closed under a set pressure (0.1–0.4 MPa) for 10–30 seconds. Under the combined action of temperature and pressure, the softened fiber molecular chains rearrange and form a stable structure according to the arc contour of the upper and lower molds. The pleats of the sleeves are flattened, the curvature is fixed, and the seams are pressed and smoothed.

[0008] During the cooling and setting stage, after pressing, the equipment can use a built-in vacuum dehumidification device or cold air system to extract moisture from between the fabric and the mold under pressure, accelerating fabric cooling. During the cooling process, the fiber molecular chains solidify in their new positions, locking in the shaping effect and preventing rebound deformation after washing or wearing.

[0009] During the mold opening and part removal stage, after cooling and solidification, the drive mechanism automatically lifts the moving mold assembly, and the operator removes the finished garment and enters the next work cycle.

[0010] The shortcomings of the existing technology are that, after the garment sleeve is put onto the lower mold shaping seat of the mold assembly and the seam allowance and threads are adjusted, the drive mechanism drives the upper mold pressing head in the moving mold assembly to press down smoothly and close the lower mold shaping seat. However, there is no limiting treatment for the garment sleeve. Since the garment fabric is a soft fabric, the operator puts it onto the lower mold shaping seat to achieve rough positioning. There is a lack of an effective limiting and fixing structure. During the process of the upper mold pressing head pressing down and closing, the sleeve is prone to displacement due to the impact of steam airflow, uneven contact friction, or accidental touch by the operator. This can lead to quality problems such as incorrect shaping position and size deviation, which seriously affects the product qualification rate. Summary of the Invention

[0011] The purpose of this invention is to provide a garment design and production shaping and pressing device to solve the technical problems in related technologies. To achieve the above objective, this invention provides the following technical solution:

[0012] A garment design and production shaping and pressing device includes a worktable with a moving mold and a fixed mold. The moving mold includes a driving component and an upper mold pressing head. The fixed mold includes a shaping base and two shaping support arms on the shaping base. The driving component drives the upper mold pressing head to press down and contact the two shaping support arms to shape and press the two sleeves of the garment. The device also includes a clamping mechanism, which includes two pairs of clamping arms arranged corresponding to the two shaping support arms. Each pair of clamping arms is placed on both sides of the corresponding shaping support arm and is arranged to swing relative to each other. After the sleeves of the garment are put on the shaping support arms and the seam allowance and grain are adjusted, the two clamping arms of each pair move closer to each other to cooperate with the shaping support arms to pre-clamp the sleeves.

[0013] As mentioned above, a protective frame is provided on the upper mold pressing head.

[0014] As mentioned above, a transmission plate is provided on the workbench, and a first elastic element is provided between the swing shaft of each clamping arm and the workbench; during the downward stroke of the protective frame following the upper molding head, the transmission plate drives each pair of clamping arms to move closer to each other based on the squeezing action of the protective frame.

[0015] The aforementioned transmission plate includes a first part that is pressed by the protective frame and a second part that is located between the two swing shafts of each pair of clamping arms; during the approach stroke of the two clamping arms of each pair, the second part transmits power to the swing shaft of each clamping arm through rolling friction; after the sleeve on the shaping support arm is pre-clamped, the rolling friction between the second part and the swing shaft of each clamping arm becomes sliding friction.

[0016] The aforementioned clamping arm includes a main section that is oscillating on the worktable and a secondary section that is slidably arranged on the main section, and a second elastic element is provided between the main section and the secondary section; after the sleeve on the shaping arm is pre-clamped, based on the squeezing action of the protective frame, the secondary section moves down to completely clamp the sleeve on the shaping arm.

[0017] The aforementioned shaping arm includes a support section fixedly connected to the shaping seat and a shaping section arranged on the support section, wherein the size of the shaping section is smaller than the size of the support section, and when the secondary section fully clamps the sleeve on the shaping arm, the part of the secondary section that clamps the sleeve is located at the junction of the shaping section and the support section.

[0018] The aforementioned sub-section includes a flexible part for clamping the sleeve and a rigid part that slides on the main section, the structure of which is adapted to the structure of the shaping arm.

[0019] As described above, the rigid section is provided with a first slide rail, within which two slide plates slide, and a third elastic element is provided between the two slide plates. A pressure plate is also provided on the rigid section, and power is transmitted between the pressure plate and each slide plate via a transmission rod. During the stroke of the pressure plate under the pressure of the protective frame, the two slide plates move in opposite directions. The main section is provided with a second slide rail. Before the flexible section reaches the junction of the shaping section and the support section, the first and second slide rails are staggered. After the flexible section reaches the junction of the shaping section and the support section, based on the pressure of the protective frame, the pressure plate drives the two slide plates to continue moving relative to each other, and one of the slide plates enters the second slide rail.

[0020] As described above, during the stroke when the upper mold pressing head presses down and contacts the two shaping support arms, part of the slide plate is in the first slide rail and the other part is in the second slide rail.

[0021] As mentioned above, the curvature of the first slide rail and the second slide rail both match the curvature of the shaped support arm.

[0022] The beneficial effects of this invention are as follows: by setting clamping arms on both sides of each shaping support arm, and by using each pair of clamping arms to move close to each other and cooperate with the corresponding shaping support arm, the garment sleeves can be pre-clamped. When the sleeves are pre-clamped, the operator can adjust the position of the garment sleeves at any time. This can effectively ensure that the garment sleeves are unlikely to shift position during shaping and pressing, thereby improving the product qualification rate. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 7 The present invention will now be described in further detail.

[0034] This invention provides a garment design and production shaping and pressing device, including a workbench 1. The workbench 1 is provided with a moving mold and a fixed mold. The moving mold includes a driving component and an upper mold pressing head 2. The fixed mold includes a shaping base 3 and two shaping support arms 30 disposed on the shaping base 3. The driving component drives the upper mold pressing head 2 to press down and contact the two shaping support arms 30 to shape and press the two sleeves of the garment. The device also includes a clamping mechanism 4, which includes two pairs of clamping arms 40 arranged corresponding to the two shaping support arms 30. Each pair of clamping arms 40 is placed on both sides of the corresponding shaping support arm 30 and is arranged to swing relative to each other. After the sleeves of the garment are put on the shaping support arms 30 and the seam allowance and threads are adjusted, the two clamping arms 40 of each pair move closer to each other and cooperate with the shaping support arms 30 to form a pre-clamping of the sleeves.

[0035] Specifically, the driving component is a cylinder or hydraulic cylinder mounted on the worktable 1. The upper mold pressing head 2 is vertically slidable on the worktable 1 and can move vertically under the drive of the driving component. The pressure applied when the moving mold contacts the fixed mold to shape and press the garment sleeve is provided by the driving component and the springs arranged on the upper mold pressing head 2. The appropriate pressing force can be set according to the thickness of the garment fabric and the shaping requirements to ensure even pressure on the sleeve and avoid shining or fabric damage. The upper mold pressing head 2 has a built-in... The electric heating element can heat the mold to 150–200℃ (adjustable according to the fabric). Some models also integrate a steam pipeline, with an external steam generator providing humid hot steam. Before / during ironing, the steam is ejected through the air holes on the upper mold ironing head 2, penetrating the fabric to quickly soften the fibers, eliminate internal stress, and create conditions for shaping. The shaping base 3 is used to fix the shaping support arm 30. The curvature of the shaping support arm 30 is arranged according to the sleeve. The shaping base 3 is fixed to the worktable 1, and the shaping support arm 30... One end is fixed to the shaping base 3, and the other end is suspended. Since the garment has two sleeves, there are also two shaping arms 30. When shaping and pressing the sleeves, the two sleeves are respectively inserted through the suspended ends of the two shaping arms 30 and moved to the middle shaping and pressing area. After the driving component moves the upper mold pressing head 2 down to contact the two shaping arms 30, pressing force is applied, thus shaping and pressing the sleeves. However, a drawback is that when the garment sleeves are inserted into the shaping arms 30... On the 0th, after adjusting the seam allowance and threads, the drive mechanism drives the upper mold pressing head 2 to press down smoothly and close with the shaping support arm 30. During this process, there is no limiting treatment for the garment sleeve. Since the garment fabric is a soft fabric, the operator puts the shaping support arm 30 on to achieve rough positioning. There is a lack of effective limiting and fixing structure. During the process of the upper mold pressing head 2 pressing down and closing, the sleeve is easily displaced due to the impact of steam airflow, uneven contact friction, or accidental touch by the operator, which in turn causes quality problems such as incorrect shaping position and size deviation.

[0036] Based on the above technical problems, in this embodiment, the sleeve is pre-clamped by the external clamping mechanism 4, which can avoid the above situation. That is, according to the shape structure of the shaping support arm 30, two clamping arms 40 are symmetrically arranged on both sides of its width direction. The two clamping arms 40 are arranged to swing relative to each other on the worktable 1. When they are close to each other, they can cooperate with the shaping support arm 30 to pre-clamp the sleeve. When they are far apart, it does not affect the sleeve being put on and taken off. When the sleeve on the shaping support arm 30 is pre-clamped, the operator can adjust the seam allowance and threads of the sleeve. During the adjustment process, the position of the sleeve is not easy to shift. In this way, the upper mold pressing head 2 presses down to cooperate with the shaping support arm 30 to perform shaping and pressing treatment on the sleeve.

[0037] In this embodiment, clamping arms 40 are provided on both sides of each shaping support arm 30. By using each pair of clamping arms 40 close to each other and cooperating with the corresponding shaping support arm 30, the garment sleeves are pre-clamped. When the sleeves are pre-clamped, the operator can adjust the position of the garment sleeves at any time. This can effectively avoid the problem of the garment sleeves shifting position during shaping and pressing, thereby improving the product qualification rate.

[0038] Preferably, a protective frame 20 is provided on the upper mold pressing head 2; specifically, since the upper mold pressing head 2 is used to provide heating, steam and pressing force, a protective frame 20 is provided to protect the personal safety of the operator in order to prevent accidents.

[0039] Preferably, the workbench 1 is provided with a transmission plate, and a first elastic element is provided between the swing shaft of each clamping arm 40 and the workbench 1; during the downward stroke of the protective frame 20 following the upper molding head 2, based on the squeezing action of the protective frame 20, the transmission plate drives each pair of clamping arms 40 to move closer to each other.

[0040] Specifically, based on the elastic force of the first elastic element, each clamping arm 40 tends to move away from the shaping support arm 30. To achieve a passive movement that causes each clamping arm 40 to move closer to the shaping support arm 30, this embodiment provides a transmission plate on the worktable 1. The transmission plate, based on the squeezing force of the downward movement of the protective frame 20, drives each clamping arm 40 to move closer to the shaping support arm 30, thereby achieving pre-clamping of the sleeve. In an optional embodiment, the transmission plate includes a first part 41 squeezed by the protective frame 20 and a second part 42 located between the two swing axes of each pair of clamping arms 40. During the approach stroke of each pair of clamping arms 40, the second part 42 transmits power to the swing axis of each clamping arm 40 through rolling friction. After the sleeve on the shaping support arm 30 is pre-clamped, the rolling friction between the second part 42 and the swing axis of each clamping arm 40 becomes sliding friction.

[0041] That is, the first part 41 is arranged vertically on the worktable 1 (in the same direction as the movement of the upper mold pressing head 2), and the second part 42 is also arranged vertically on the worktable 1. Since there are two shaping arms 30, there are also two second parts 42. Each shaping arm 30 corresponds to one second part 42. One second part 42 is arranged between the two swing axes of each pair of clamping arms 40. There is a frictional force between the swing axis and the second part 42. When the swing of the clamping arm 40 is not restricted, the friction between its swing axis and the second part 42 is rolling friction. When the swing is restricted, the friction between the swing axis and the second part 42 becomes sliding friction, and the movement of the second part 42 no longer drives the swing axis to rotate. Therefore, during the process of the first part 41 being squeezed by the protective frame 20, the second part 42 uses rolling friction to drive each pair of clamping arms 40 to move closer to each other and cooperate with the corresponding shaping support arm 30 to pre-clamp the sleeve. After the second part 42 continues to move, the clamping arms 40 can no longer swing. Therefore, after the sleeve is pre-clamped, the sleeve needs to be shaped and pressed. The protective frame 20 will not be obstructed during the process of being carried along.

[0042] Furthermore, the clamping arm 40 includes a main section 400 that is oscillating on the worktable 1 and a secondary section 401 that is slidably arranged on the main section 400, and a second elastic element is provided between the main section 400 and the secondary section 401; after the sleeve on the shaping arm 30 is pre-clamped, based on the squeezing action of the protective frame 20, the secondary section 401 moves down to completely clamp the sleeve on the shaping arm 30.

[0043] Specifically, during the pre-clamping of the sleeve, the movement direction of the secondary section 401 on the main section 400 is consistent with the movement direction of the upper mold pressing head 2. The second elastic element, with the main section 400 as a reference, has an elastic force that tends to push the secondary section 401 upwards. To further eliminate the possibility of fabric slippage during the downward pressing process, after the sleeve is pre-clamped, as the upper mold pressing head 2 contacts the shaping support arm 30, the squeezing action of the protective frame 20 causes the secondary section 401 to move downwards, cooperating with the shaping support arm 30 to move the sleeve from pre-clamping to full clamping. In an optional embodiment, the shaping arm 30 includes a support section 300 fixedly connected to the shaping base 3 and a shaping section 301 arranged on the support section 300. The size of the shaping section 301 is smaller than that of the support section 300. When the secondary section 401 fully clamps the sleeve on the shaping arm 30, the part of the secondary section 401 that clamps the sleeve is located at the junction of the shaping section 301 and the support section 300. The purpose is that the part of the secondary section 401 that fully clamps the sleeve can be a certain distance away from the shaping and pressing position, so as to avoid contact with the upper mold pressing head 2 and cause the sleeve to deform.

[0044] Furthermore, the secondary section 401 includes a flexible portion 402 for clamping the sleeve and a rigid portion 403 that is slidably arranged on the main section 400. The structure of the flexible portion 402 is adapted to the structure of the shaping arm 30.

[0045] Specifically, the flexible part 402 makes flexible contact with the sleeve, and during the process from pre-clamping the sleeve to fully clamping the sleeve, it can avoid scratching the surface of the sleeve. When the sleeve is pre-clamped, in the vertical downward projection, the flexible part 402 overlaps with the shaping section 301. During the process from pre-clamping to full clamping, the flexible part 402 will undergo elastic deformation to reach the junction of the shaping section 301 and the support section 300. During this process, the sleeve can be smoothed out from the side door.

[0046] In this embodiment, the secondary segment 401 moves from the pre-clamped sleeve position to the fully clamped sleeve position under the squeezing action of the protective frame 20. After this, the protective frame 20 will continue to move downwards. The secondary segment 401 must either follow it or avoid it. Following it cannot achieve full clamping of the sleeve. If it avoids it, it tends to return to the pre-clamped position due to the rebound force of the second elastic element. Therefore, in an optional embodiment, the rigid part 403 is provided with a first slide rail 43, and two slide plates 44 are slidably arranged in the first slide rail 43, with a third elastic element between the two slide plates 44. The rigid part 403 is also slidably provided with... The pressure plate 45 transmits power to each slide plate 44 via a transmission rod 46. During the stroke of the pressure plate 45 under the compression of the protective frame 20, the two slide plates 44 move in opposite directions. The main section 400 is provided with a second slide rail 47. Before the flexible part 402 reaches the junction of the shaping section 301 and the support section 300, the first slide rail 43 and the second slide rail 47 are staggered. After the flexible part 402 reaches the junction of the shaping section 301 and the support section 300, based on the compression of the protective frame 20, the pressure plate 45 drives the two slide plates 44 to continue to move relative to each other, and one of the slide plates 44 enters the second slide rail 47.

[0047] Specifically, when the protective frame 20 first contacts the pressure plate 45, the first slide rail 43 and the second slide rail 47 are misaligned due to the elastic force of the second elastic element. As the protective frame 20 continues to compress, the pressure plate 45 pushes the slide plate 44 from the first slide rail 43 towards the second slide rail 47 via the transmission rod 46, until it is blocked by the main section 400. Then, as the protective frame 20 continues to compress, the secondary section 401 moves downward as a whole, and the flexible part 402 moves from the pre-clamped sleeve position to the fully clamped sleeve position. Then, the first slide rail 43 and the second slide rail 47 are connected. As the protective frame 20 continues to move downward, the pressure plate 45 will then move downward via the transmission rod 46. The lever 46 pushes the slide plate 44 into the second slide rail 47. In an optional embodiment, during the stroke of the upper mold pressing head 2 pressing down and contacting the two shaping support arms 30, part of the slide plate 44 is in the first slide rail 43 and the other part is in the second slide rail 47. The curvature of the first slide rail 43 and the second slide rail 47 both match the curvature of the shaping support arms 30. Then the sub-section 401 will not continue to move down, but will be in the position of fully clamping the sleeve. Therefore, the sleeve will not be affected by being fully clamped, and the protective frame 20 can continue to move down. The upper mold pressing head 2 can smoothly contact the shaping support arms 30 to complete the shaping and pressing operation of the sleeve.

[0048] Furthermore, a support rod 48 is installed at the end of each slide 44 away from the transmission rod 46. The support rod 48 is bent, and a block 49 is installed at the end away from the slide 44. When the sleeves on the shaping support arms 30 of each pair of clamping arms 40 are pre-clamped, the block 49 on each support rod 48 will press on the area of ​​the sleeve that needs to be shaped and pressed. Therefore, when the operator puts the sleeve on the shaping support arm 30, the end of the sleeve that needs to be shaped and pressed is placed in the position where the block 49 will press it down. Then, as the two slides 44 move away from each other in the same first slide rail 43, the relative movement of the two corresponding blocks 49 can pull on the sleeve, making the sleeve... The area to be shaped and pressed can be straightened and flattened. To better straighten and flatten the area to be shaped and pressed, the block 49 has a slot 50. When the sleeve is pre-clamped, the size of the slot 50 will decrease due to the squeezing action. When the end of the area to be shaped and pressed is placed in the slot 50, it will not easily come off during the straightening process of the sleeve. It will also prevent the sleeve from curling due to the friction between the shaping section 301 and the sleeve. After the sleeve is fully clamped, the protective frame 20 continues to move down and will squeeze the pressure plate 45. The slide plate 44 will then enter the second slide rail 47 and continue to slide, which will cause the block 49 to separate from the sleeve, thus avoiding obstruction of the shaping and pressing of the sleeve.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
