Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing, and more particularly to a shaping machine for shaping tubular fabrics. Background Art

[0002] Existing fabric shaping equipment, especially shaping equipment for tubular fabrics, is equipped with several shaping mechanisms. The tubular fabric is put on these shaping mechanisms, the tubular fabric is stretched by shaping rollers, and then the shaping mechanisms are driven to drive the tubular fabric to rotate flexibly, thereby shaping the tubular fabric.

[0003] For example, patent application publication number CN111206359A discloses a CNC shaping machine comprising a shaping frame, an oven, and a shaping mechanism, further comprising a movable seat and a drive assembly. The movable seat is mounted on the shaping frame via a slideway, the shaping mechanisms are mounted on corresponding movable seats, and are located on the same side of the shaping frame as the oven. The drive assembly drives the movable seat to move back and forth along the shaping frame, and the oven is provided with at least one entrance for the shaping mechanism to enter and exit the oven. Each layer of the shaping mechanism comprises four sets of shaping assemblies, the four sets of shaping assemblies being symmetrically distributed on the left and right sides of the shaping frame, the oven being arranged on the left and right sides of the shaping frame and located in the middle of the shaping frame, and the two sets of shaping assemblies of the shaping mechanism on each layer on the same side of the shaping frame alternately enter and exit the corresponding oven. The shaping component includes two shaping rollers, which are arranged horizontally and parallel. One end of the shaping roller is rotatably mounted on a movable seat, and the other end extends to the outside of the shaping frame. A rotating component for driving the shaping roller to rotate is provided on the movable seat.

[0004] This heat setting machine uses several heat setting rollers to stretch the tubular fabric. The rollers are then driven to rotate around their axes, causing the tubular fabric to flexibly rotate and set. However, the heat setting rollers can only set the tubular fabric in the radial and circumferential directions, but not in the axial direction. The tubular fabric is more prone to curling and wrinkling in the axial direction, especially at the sides. Failure to stretch the tubular fabric in this direction to achieve the desired dimensions for heat setting will reduce the heat setting quality. Summary of the Invention

At the same time, by providing a fabric wrapping portion and a pressing device adapted to the fabric wrapping portion and arranged on the setting machine body, when the fabric wrapping device with the tubular fabric wrapped is placed in the setting area, the pressing device and the fabric wrapping portion together form a fabric stretching mechanism for stretching the tubular fabric along the axial direction of the support shaft, thereby stretching and extending the fabric, stretching the axial dimension of the tubular fabric to the required dimension for heat setting, eliminating defects in the fabric (such as curling, wrinkles, hemming, etc.), and making the fabric flat, thereby improving the setting quality of the fabric.

DETAILED DESCRIPTION

[0074] The present invention is specifically described below with reference to the embodiments:

[0075] Example:

[0076] A shaping machine for shaping tubular fabrics, as shown in the attached Figure 1 To the attached Figure 10 As shown, it includes a setting machine body 8 for heat setting the fabric, which has a setting area where a heat setting device is set to perform heat setting on the fabric; the setting area is connected to the external space of the setting machine body 8 through an opening on the setting machine body 8, that is, the setting area has a feeding port connected to the external space, so that articles in the external space of the setting machine body 8 can enter and exit the setting area.

[0077] As attached Figure 1 and attached Figure 3As shown, a shift seat 9 is provided, which is movably (including sliding or rotating) connected to the setting machine body 8. In this embodiment, the shift seat 9 is slidably connected to the setting machine body 8; and the fabric set device is connected to the shift seat 9. The moving path of the shift seat 9 on the setting machine body 8 is adapted to the setting area and the external space of the setting machine body 8, so that the shift seat 9 can be moved, as shown in the attached figure. Figure 1 As shown, the fabric wrapping device is placed in the external space of the setting machine body 8 to wrap the tubular fabric on the fabric wrapping device, or as shown in the attached Figure 2 As shown, the fabric set device is placed in the shaping area to perform heat setting treatment on the fabric.

[0078] In this embodiment, the shaping machine body 8 is provided with a slide rail 801 for sliding installation of the shift seat 9, and the slide rail 801 extends in the direction from the shaping area to the external space of the shaping machine body 8, and the shaping machine body 8 is also provided with a rotating motor for driving the shift seat 9 to slide, and the rotating output shaft of the rotating motor is connected to the driving rod, and the shift seat 9 is screwed to the driving rod.

[0079] As attached Figure 1 As shown, the fabric covering device in this embodiment includes a fabric covering portion for covering a cylindrical fabric.

[0080] Specifically, as attached Figure 1 , Attachment Figure 2 and attached Figure 4 As shown, the fabric sleeve portion in this embodiment includes: a support shaft 1, a first pressing sleeve 1a and a second pressing sleeve 1b that can be movably sleeved on the outer circumference of the support shaft 1. In addition, the first pressing sleeve 1a and the second pressing sleeve 1b are connected to a pressing sleeve driving device 2 that drives the first pressing sleeve 1a and the second pressing sleeve 1b to move closer to or away from each other on the support shaft 1.

[0081] At the same time, as attached Figure 2 As shown, the setting machine body 8 is further provided with a pressing device that matches the fabric sheathing portion when placed in the setting area and can provide pressure to the tubular fabric sheathed around the outer periphery of the fabric sheathing portion. When the fabric sheathing portion is placed in the setting area, the pressing device and the fabric sheathing portion together form a fabric stretching mechanism that stretches the tubular fabric along the axial direction of the support shaft 1. The specific structure of the fabric stretching mechanism and its stretching effect on the fabric will be described in detail below.

[0082] When the inner diameter of the tubular fabric is larger than the outer diameter of the fabric sheath portion, the tubular fabric is easily displaced and the fabric cannot be stretched as required.

[0083] Therefore, the fabric sheathing device also includes a structure for stretching the tubular fabric sheathed on the fabric sheathing portion, that is, stretching the tubular fabric in a direction other than the axial direction of the support shaft 1. The tubular fabric can be stretched to a desired diameter.

[0084] As attached Figure 1 As shown, the fabric encasement device in this embodiment further includes: a first linkage seat 10 , a second linkage seat 11 , a first support rod 12 and a second support rod 13 .

[0085] Specifically, the first linkage seat 10 is arranged on one side of the shift seat 9 to match the sliding path of the shift seat 9, and it can slide along with the shift seat 9 and can slide relative to the shift seat 9 in the sliding direction of the shift seat 9. In this embodiment, the shift seat 9 is rotatably connected to the adjustment screw 901, the extension direction of the adjustment screw 901 conforms to the sliding direction of the shift seat 9, and the shift seat 9 is fixedly connected to a rotating motor, which is transmission-connected to the adjustment screw 901 to drive the adjustment screw 901 to rotate. The first linkage seat 10 is slidably connected to the slide rail 801 and is screwed onto the adjustment screw 901, so that when the adjustment screw 901 is not rotating, the first linkage seat 10 can slide along with the shift seat 9; and when the adjustment screw 901 rotates, the first linkage seat 10 can slide relative to the shift seat 9 in the sliding direction of the shift seat 9.

[0086] Similarly, the second linkage seat 11 is arranged on the other side of the shift seat 9 to match the sliding path of the shift seat 9. It can slide with the shift seat 9 and can slide relative to the shift seat 9 in the sliding direction of the shift seat 9. In this embodiment, the second linkage seat 11 is slidably connected to the slide rail 801 and screwed to the adjustment screw 901. When the adjustment screw 901 is not rotating, the second linkage seat 11 can slide with the shift seat 9; when the adjustment screw 901 rotates, the second linkage seat 11 can slide relative to the shift seat 9 in the sliding direction of the shift seat 9.

[0087] The first support rod 12 is placed on one side of the support shaft 1 and connected to the first linkage seat 10 , and the second support rod 13 is placed on the other side of the support shaft 1 and connected to the second linkage seat 11 .

[0088] At this time, the fabric sheathing part, the first strut 12 and the second strut 13 jointly sheath the tubular fabric, and by driving the first linkage seat 10 and the second linkage seat 11 to slide relative to the shift seat 9, the first strut 12 and the second strut 13 can be moved away from the support shaft 1, thereby stretching the sheathed tubular fabric.

[0089] Furthermore, in order to drive the expanded tubular fabric to rotate, the fabric stretching mechanism can stretch different surfaces of the tubular fabric.

[0090] In this embodiment, the first support rod 12 is rotatably connected to the first linkage seat 10, and is transmission-connected to a rotating motor (not shown in the figure) connected to the first linkage seat 10 and providing rotational force to the first support rod 12, so that the rotating motor drives the first support rod 12 to rotate, thereby driving the expanded tubular fabric to rotate.

[0091] Of course, the second support rod 13 can also be rotatably connected to the second linkage seat 11, and is transmission-connected to another rotating motor (not shown in the figure) connected to the second linkage seat 11 and providing rotational force to the second support rod 13, so that the rotating motor drives the second support rod 13 to drive the expanded tubular fabric to rotate.

[0092] For fabric stretching mechanism:

[0093] In order to facilitate the description of the structure of the fabric stretching mechanism and the specific stretching action, the following description assumes that the fabric wrapping device is placed in the shaping area, and the pressing device and the fabric wrapping part together form the fabric stretching mechanism (see attached diagram). Figure 2 , Attachment Figure 4 The fabric stretching mechanism, the fabric covering portion and the pressing device constituting the fabric stretching mechanism are described in detail.

[0094] As attached Figure 4 To the attached Figure 7 As shown, the fabric sleeve portion includes a laterally extending support shaft 1, and a first pressing sleeve 1a and a second pressing sleeve 1b are movably sleeved on the outer periphery of the support shaft 1, and the first pressing sleeve 1a and the second pressing sleeve 1b are connected to a pressing sleeve driving device 2 that drives the first pressing sleeve 1a and the second pressing sleeve 1b to move closer to / away from each other on the support shaft 1.

[0095] At the same time, a twisting shaft 3 rotatably connected to the forming machine body 8 is arranged above the support shaft 1 at intervals. It is preferably extended horizontally, and the extension direction of the twisting shaft 3 is preferably in line with (preferably parallel, considering manufacturing and installation limitations, angular deviation is allowed) the extension direction of the support shaft 1.

[0096] In this embodiment, one end of the rotating shaft 3 is drivingly connected to a rotating shaft drive device 4 that provides rotational force. The gap between the rotating shaft 3 and the support shaft 1 forms a feed space for the fabric to travel. More specifically, the gap between the rotating shaft 3 and the support shaft 1 forms a feed space for the fabric to travel from one side of the support shaft 1 to the other. The specific size of this gap can be adjusted to suit the fabric size.

[0097] At the same time, the twisting shaft 3 is linked to a pressing assembly 5 that rotates with the twisting shaft 3 and moves closer to or further away from the support shaft 1. The pressing assembly 5 is adapted to be arranged in the moving area of ​​the first pressing sleeve 1a and the moving area of ​​the second pressing sleeve 1b, so that when the pressing assembly 5 is close to the support shaft 1, a portion of the pressing assembly 5 always exists to form a clamping structure for the fabric together with the movable first pressing sleeve 1a, and another portion of the pressing assembly 5 always exists to form a clamping structure for the fabric together with the movable second pressing sleeve 1b. Symmetrical clamping is preferred.

[0098] In the above scheme, the fabric is placed in the material feeding space between the twisting shaft 3 and the support shaft 1, and the twisting shaft 3 is driven to rotate to drive the pressing assembly 5 to move close to the support shaft 1 until: part of the pressing assembly 5 (for example, the first rod 501a below) and the first pressing sleeve 1a together form a clamping structure for the fabric, and at the same time, another part of the pressing assembly 5 (for example, the second rod 501b below) and the second pressing sleeve 1b together form a clamping structure for the fabric, so that the fabric can be clamped; at the same time, the pressing sleeve driving device 2 drives the first pressing sleeve 1a and the second pressing sleeve 1b to move away from each other on the support shaft 1, so that the first pressing sleeve 1a and the second pressing sleeve 1b pressing the fabric can be moved to both sides respectively, and the fabric can be pushed horizontally in the moving direction of the pressing sleeve (the axial direction of the tubular fabric) to achieve stretching and extension of the fabric, so as to improve the quality of the subsequent shaping of the fabric.

[0099] After stretching, the twisting shaft 3 needs to be driven to rotate to drive the pressing assembly 5 away from the support shaft 1, releasing the clamping state of the fabric and moving the unstretched part of the fabric into the feeding space for stretching. At the same time, when the fabric is clamped, the pressing sleeve driving device 2 can be used to drive the first pressing sleeve 1a and the second pressing sleeve 1b closer together on the support shaft 1, preparing for the next stretching of the fabric. After preparation is completed, the above-mentioned stretching action of the fabric can be repeated.

[0100] Furthermore, in order to avoid interference with the movement of the fabric, in this embodiment, as shown in the attached Figure 4 and attached Figure 5 As shown, the sleeve pressing drive device 2 includes a first lead screw 201 , a first connecting sleeve 202 , a second lead screw 203 , and a second connecting sleeve 204 disposed in the support shaft 1 .

[0101] Specifically, the first screw 201 is adapted to the position of the first pressing sleeve 1a and is rotatably inserted into the support shaft 1. The first connecting sleeve 202 is threaded on the first screw 201. The first connecting sleeve 202 is protrudingly formed with a first sliding groove 101 that passes through the support shaft 1 and is fixed to the first pressing sleeve 1a. The first connecting portion 2021 is fixedly connected to the first pressing sleeve 1a.

[0102] At the same time, the second screw 203 is adapted to the position of the second pressing sleeve 1b and is rotatably inserted into the support shaft 1. A second connecting sleeve 204 is screwed on the second screw 203. The second connecting sleeve 204 is protrudingly formed with a second sliding groove 102 that passes through the support shaft 1 and is fixed to the second pressing sleeve 1b. A second connecting part 2041 is fixedly connected to the second pressing sleeve 1b.

[0103] In one driving mode, the first screw 201 and the second screw 203 can be respectively connected to a rotating motor that provides rotational force to the screw. The rotating motor is fixedly connected to the shift seat 9. The first screw 201 and the second screw 203 are synchronously driven to rotate by the two rotating motors to drive the first pressing sleeve 1a and the second pressing sleeve 1b to approach / move away from each other on the support shaft 1.

[0104] Of course, the first screw 201 and the second screw 203 can also be coaxially integrally formed into a screw member, and the screw member is connected to a screw rotating motor 206 that provides rotational force to the screw member, and the screw rotating motor 206 is fixedly connected to the shift seat 9.

[0105] Or, in another form, as in the attached Figure 4 , Attachment Figure 5 As shown, the first screw 201 and the second screw 203 are connected by a transmission rod 205, and the outer end of the first screw 201 or the outer end of the second screw 203 is connected to a screw rotating motor 206 that provides rotational force to the screw, and the screw rotating motor 206 is fixedly connected to the shift seat 9.

[0106] Specifically, in this embodiment, the outer end of the first lead screw 201 is transmission-connected to a drive rod 207, and a drive rod connecting gear 2071 is fixedly connected to the outer periphery of the drive rod 207. The drive rod connecting gear 2071 is meshedly connected with a lead screw driving gear 2061 fixedly connected to the rotation output shaft of the lead screw rotating motor 206, so that the lead screw rotating motor 206 can drive the first lead screw 201 and the second lead screw 203 to rotate synchronously. At this time, the thread rotation direction of the first lead screw 201 and the second lead screw 203 matches the movement setting of the pressing sleeve, so that when the lead screw driving gear 2061 drives the drive rod 207 to rotate in the forward direction, the first pressing sleeve 1a and the second pressing sleeve 1b are closer to each other on the support shaft 1; when the drive rod 207 is driven to rotate in the reverse direction, the first pressing sleeve 1a and the second pressing sleeve 1b are separated from each other on the support shaft 1.

[0107] Furthermore, the rotating shaft driving device 4 in this embodiment can be a rotating motor that can directly drive the rotating shaft 3 to rotate.

[0108] Or, as attached Figure 4As shown, the twisting shaft driving device 4 in this embodiment includes a cylinder 401 fixedly connected to the forming machine body 8, a push block 402 is fixedly connected to the piston rod of the cylinder 401, and a twisting shaft transmission gear 302 is fixedly connected to the outer periphery of the twisting shaft 3, and the push block 402 is meshedly connected with the twisting shaft transmission gear 302, so that when the cylinder 401 drives the piston rod to move back and forth in a straight line, it can drive the twisting shaft 3 to rotate forward / reverse.

[0109] Furthermore, as attached Figure 4 , Attachment Figure 6 As shown, the pressing assembly 5 in this embodiment includes a pressing rod 501 and a mounting member 502 .

[0110] Specifically, the pressing rod 501 is adapted to the moving area of ​​the first pressing sleeve 1a and the moving area of ​​the second pressing sleeve 1b, and is provided with a part for forming a fabric clamping structure together with the first pressing sleeve 1a, and a part for forming a fabric clamping structure together with the second pressing sleeve 1b.

[0111] At the same time, the pressing rod 501 is linked to the rotating shaft 3 through several mounting parts 502. Each mounting part 502 is connected to the rotating shaft 3 at one end and to the pressing rod 501 at the other end, so that the rotating rotating shaft 3 can drive the pressing rod 501 closer to or away from the support shaft 1 through the mounting part 502.

[0112] The pressing rod 501 may be a long rod structure extending laterally in accordance with the extension direction of the support shaft 1 .

[0113] However, considering that the wrinkles and curling degrees on both sides of the fabric are generally different or the weaving structure of the fabric has different thicknesses on both sides, there will be differences in the thickness of the two sides of the fabric. A single long rod structure cannot adapt to the thickness of the two sides of the fabric well to clamp and stretch the fabric.

[0114] Based on this, as attached Figure 4 As shown, the press rod 501 in this embodiment includes: a first rod 501a extending transversely in accordance with the extension direction of the support shaft 1, and a second rod 501b extending transversely in accordance with the extension direction of the support shaft 1, which are spaced apart. The first rod 501a is adapted to be arranged in the moving area of ​​the first pressing sleeve 1a, and has a portion for forming a fabric clamping structure together with the first pressing sleeve 1a; as shown in the attached figure, Figure 4 As shown, the first rod 501a is linked to the rotating shaft 3 through a plurality of mounting members 502, so that when the rotating shaft 3 rotates, the first rod 501a can be synchronously driven to move closer to or away from the first pressing sleeve 1a. The second rod 501b is adapted to be arranged in the moving area of ​​the second pressing sleeve 1b, and has a portion for forming a fabric clamping structure together with the second pressing sleeve 1b; as shown in the attached Figure 4As shown, the second rod 501b is linked to the rotating shaft 3 through a plurality of mounting members 502, so that when the rotating shaft 3 rotates, the second rod 501b can be synchronously driven to move closer to or away from the second pressing sleeve 1b.

[0115] In this way, the first rod 501a and the first pressing sleeve 1a, and the second rod 501b and the second pressing sleeve 1b can form two independent but synchronously operating stretching structures for the fabric, which can more specifically clamp and stretch the two sides of the fabric with different thicknesses; so as to have a targeted stretching and extension effect on the entire fabric, thereby better improving the quality of the subsequent shaping of the fabric.

[0116] At the same time, considering that there are still areas of different thicknesses near the single-side edge of the fabric, when the pressing sleeve is not moved, the thicker part of the fabric will be piled up in the area between the pressing rod 501 and the support shaft 1, which will not affect the clamping of the pressing rod 501 and the pressing sleeve. However, when the pressing sleeve moves, since the position of the pressing rod 501 cannot be adjusted, the spacing area between the pressing sleeve and the pressing rod 501 is fixed. When this spacing area cannot accommodate the part of the fabric that is difficult to flatten, the moving pressing sleeve is likely to cause pulling and damage to the fabric. In particular, this situation is more likely to occur when the fabric is stretched while moving.

[0117] Based on this, as attached Figure 4 and attached Figure 6 As shown, in this embodiment, one end of the mounting member 502 is rotatably connected to the rotating shaft 3; and, a shaft sleeve 301 is fixedly connected to the rotating shaft 3 to adapt to the mounting member 502, and a torsion spring 7 is also mounted on the rotating shaft 3, and the torsion spring 7 is placed between the shaft sleeve 301 and the mounting member 502, and one end of the torsion spring 7 is fixedly connected to the shaft sleeve 301, and the other end is fixedly connected to the mounting member 502.

[0118] In this way, when the rotating shaft 3 rotates, the pressing assembly 5 is driven to rotate along with the rotating shaft 3 and approach the pressing sleeves 1a and 1b. The gap between the pressing assembly and the pressing sleeves is adaptive to the thickness of the fabric through the torsion spring 7. That is, when the portion of the fabric with excessive thickness interferes with the pressing sleeve, the interference force is transmitted to the torsion spring 7 through the pressing assembly 5, driving the pressing assembly 5 to rotate and lift relative to the rotating shaft 3, thereby increasing the gap between the pressing sleeve and the pressing rod 501 to accommodate the portion of the fabric with excessive thickness, thereby accommodating the portion that is difficult to flatten, and realizing automatic elastic adjustment of the clamping of the fabric according to the thickness distribution of the fabric, thereby reducing the possibility of over-pressure damage to the fabric caused by the moving pressing sleeve, and improving the stability of the fabric stretching and expansion.

[0119] The fabric stretching mechanism can stretch a moving fabric, but this requires time for the first and second pressing sleeves 1a, 1b to return to the stretching starting point of the support shaft 1, depending on the fabric's travel speed and stretching time. Alternatively, the mechanism can stretch a statically placed fabric, achieving a cycle of fabric stretching and fabric movement. In this case, the fabric travel time is the time it takes for the first and second pressing sleeves 1a, 1b to return to the stretching starting point of the support shaft 1. The stretching starting point is set based on the actual fabric size.

[0120] As attached Figure 4 As shown, in this embodiment, the support shaft 1 is rotatably arranged to better drive the tubular fabric sleeved around the outer periphery of the fabric sleeve portion to rotate. For example, it is rotatably mounted on a shift seat 9, and the support shaft 1 is drivingly connected to a support shaft rotation motor 6 that provides rotational force thereto. The support shaft rotation motor 6 is fixedly connected to the shift seat 9. At this time, by controlling the rotational speed of the first lead screw 201 relative to the support shaft 1 and the rotational speed of the second lead screw 203 relative to the support shaft 1, the movement of the first pressing sleeve 1a and the second pressing sleeve 1b can be driven and adjusted, thereby achieving synchronous operation of fabric movement and stretching.

[0121] Specifically, as attached Figure 4 As shown, a support shaft transmission gear 103 is fixedly connected to the outer periphery of the support shaft 1 , and a first driving gear 601 is fixedly connected to the output shaft of the support shaft rotation motor 6 . The first driving gear 601 is meshed with the support shaft transmission gear 103 .

[0122] At the same time, in order to meet the need of stretching the moving fabric, the pressing rod 501 includes a pressing roller 501c that is rotatably set and used to connect with the fabric; and the rotation direction of the pressing roller 501c is matched with the rotation direction of the support shaft 1, so that when the support shaft 1 is connected to the pressing roller 501c, the rotating support shaft 1 can drive the pressing roller 501c to rotate synchronously.

[0123] As attached Figure 4 As shown, when the first rod 501a and the second rod 501b are set.

[0124] The first rod 501a includes a first pressing roller 501c1 that is rotatably arranged and used to connect with the cloth; and the rotation direction of the first pressing roller 501c1 is matched with the rotation direction of the support shaft 1, so that when the support shaft 1 is connected with the first pressing roller 501c1, the rotating support shaft 1 can drive the first pressing roller 501c1 to rotate synchronously.

[0125] The second rod 501b includes a second pressing roller 501c2 that is rotatably arranged and used to connect with the cloth; and the rotation direction of the second pressing roller 501c2 is matched with the rotation direction of the support shaft 1, so that when the support shaft 1 is connected with the second pressing roller 501c2, the rotating support shaft 1 can drive the second pressing roller 501c2 to rotate synchronously.

[0126] Or, as attached Figure 10 As shown, the outer periphery of the first rod 501a is rotatably fitted with a first pressing roller 501c1 that can move along the extension direction of the first rod 501a; the outer periphery of the second rod 501b is rotatably fitted with a second pressing roller 501c2 that can move along the extension direction of the second rod 501b.

[0127] In this way, when the fabric is stretched, the first nip roller 501c1 and the first pressing sleeve 1a jointly clamp a portion of the fabric, and the fabric is stretched by driving the first pressing sleeve 1a to move. Under the action of the first pressing sleeve 1a, the first nip roller 501c1 can also move with the first pressing sleeve 1a, reducing the possibility that the fabric will be piled up on the surface of the first nip roller 501c1 under the pressure of the first pressing sleeve 1a and cannot be stretched well. Similarly, at this time, the second nip roller 501c2 can also move with the movement of the second pressing sleeve 1b, reducing the possibility that the fabric will be piled up on the surface of the second nip roller 501c2 under the pressure of the second pressing sleeve 1b and cannot be stretched well.

[0128] Furthermore, when the first rod 501a and the second rod 501b move away from the support shaft 1 synchronously, the first nip roller 501c1 and the second nip roller 501c2 can be reset to the stretching starting position.

[0129] As attached Figure 10 As shown, in this embodiment, both ends of the first pressing roller 501c1 are provided with mounting parts 502 that link the first rod 501a to the rotating shaft 3; and, between the end of the first pressing roller 501c1 and a mounting part 502 adjacent to the end, a reset part 503 is provided to drive the moving first pressing roller 501c1 to reset. The reset part 503 is preferably a spring or a component similar to a spring that can provide a reset elastic force.

[0130] As attached Figure 10 As shown, in this embodiment, both ends of the second pressing roller 501c2 are provided with mounting parts 502 that link the second rod 501b to the rotating shaft 3; and, a reset part 503 is provided between the end of the second pressing roller 501c2 and a mounting part 502 adjacent to the end to drive the moving second pressing roller 501c2 to reset. The reset part 503 is preferably a spring or a component similar to a spring that can provide a reset elastic force.

[0131] Further:

[0132] Considering the limited travel of the press sleeve, it is difficult to stretch the fabric to the required size with a single stretch.

[0133] Therefore, as attached Figure 1 , Attachment Figure 7 , Attachment Figure 8 As shown, the fabric suiting device includes two fabric suiting parts arranged laterally spaced apart; and, the forming machine body 8 is adapted to be provided with a pressing device (refer to the description of the pressing device above) for each fabric suiting part, so that when the fabric suiting device is placed in the forming area, two laterally spaced fabric stretching mechanisms can be formed.

[0134] At this time, as attached Figure 2 , Attachment Figure 7 and attached Figure 8 As shown, the two fabric stretching mechanisms are arranged laterally at intervals, and the feeding space in one fabric stretching mechanism is laterally aligned with the feeding space in the other fabric stretching mechanism, so that after the fabric is stretched and output from the feeding space of one fabric stretching mechanism, it can enter the feeding space of the other fabric stretching mechanism for stretching again, so that the fabric can pass through the two fabric stretching mechanisms in sequence to achieve alternating working and continuous stretching, so that the fabric can be stretched to the required size, thereby improving the quality of the subsequent shaping of the fabric.

[0135] As attached Figure 8 As shown, in order to avoid the interference hidden danger of the rotation of the pressing assembly 5, it is preferred that the pressing assembly 5 of one fabric stretching mechanism is arranged opposite to the pressing assembly 5 of another fabric stretching mechanism.

[0136] Furthermore, in order to achieve smooth movement of the fabric, the support shaft 1 in one fabric stretching mechanism and the support shaft 1 in another fabric stretching mechanism preferably rotate at the same speed and direction; based on this, in this embodiment, the support shaft 1 in one fabric stretching mechanism and the support shaft 1 in another fabric stretching mechanism are both transmission-connected to a support shaft rotating motor 6.

[0137] Specifically, a first drive gear 601 and a second drive gear 602 are fixedly connected to the rotating output shaft of the support shaft rotating motor 6 at intervals. The support shaft transmission gear 103 on the support shaft 1 in one fabric stretching mechanism is meshed with the first drive gear 601, and the support shaft transmission gear 103 on the support shaft 1 in the other fabric stretching mechanism is meshed with the second drive gear 602.

[0138] The stretching and advancement of the fabric are preferably performed synchronously, that is, the fabric is stretched while the support shaft 1 is rotated to drive the fabric to advance.

[0139] At this time, if the pressing assembly 5 in one fabric stretching mechanism and the pressing assembly 5 in another fabric stretching mechanism operate synchronously, that is, the pressing assembly 5 in one fabric stretching mechanism and the pressing assembly 5 in another fabric stretching mechanism press the fabric synchronously, time must be reserved for the pressing assembly 5 in one fabric stretching mechanism and the pressing assembly 5 in another fabric stretching mechanism to be synchronously separated from the fabric so that the pressing sleeve can return to the stretching starting point of the support shaft 1, which will affect the stretching efficiency of the fabric.

[0140] When the pressing assembly 5 in one fabric stretching mechanism and the pressing assembly 5 in another fabric stretching mechanism clamp the fabric synchronously, the pressing and clamping effect on the fabric will be too large, affecting the fabric from moving smoothly and further affecting the overall stretching effect.

[0141] When the pressing assembly 5 in one fabric stretching mechanism and the pressing assembly 5 in another fabric stretching mechanism move away from the fabric synchronously, the moving fabric will have no guide limit, and the fabric will easily wrinkle during the moving process, which will hinder the stretching action of the fabric.

[0142] Based on this, in this embodiment, the two fabric stretching mechanisms are preferably arranged to operate alternately to alternately stretch the fabric. Specifically, one fabric stretching mechanism (primarily referring to the sleeve-pressing drive device 2 and the twisting shaft drive device 4 therein) and the other fabric stretching mechanism (primarily referring to the sleeve-pressing drive device 2 and the twisting shaft drive device 4 therein) are arranged to operate alternately, allowing one fabric stretching mechanism and the other fabric stretching mechanism to alternately stretch the fabric. This stretching operation includes providing stretching, pressing, and even twisting effects on the fabric during stretching. (For ease of description, one fabric stretching mechanism will be referred to as the first fabric stretching mechanism, and the other fabric stretching mechanism will be referred to as the second fabric stretching mechanism.)

[0143] That is, in the first step, the pressing assembly 5 of the first fabric stretching mechanism is close to the support shaft 1 of the first fabric stretching mechanism to clamp the fabric with the two pressing sleeves of the first fabric stretching mechanism and drive the two pressing sleeves to move to perform the first stretching treatment on the fabric; the pressing assembly 5 of the second fabric stretching mechanism is away from the support shaft 1 of the second fabric stretching mechanism, so that the two pressing sleeves of the second fabric stretching mechanism can be reset and moved to the stretching starting point of the support shaft 1 of the second fabric stretching mechanism, preparing for the secondary stretching of the fabric.

[0144] In the second step, the pressing assembly 5 of the first fabric stretching mechanism is away from the support shaft 1 of the first fabric stretching mechanism, and the two pressing sleeves of the first fabric stretching mechanism can be reset and moved to the stretching starting point of the support shaft 1 of the first fabric stretching mechanism; at the same time, the pressing assembly 5 of the second fabric stretching mechanism is close to the support shaft 1 of the second fabric stretching mechanism, so as to clamp the fabric flowing out of the first fabric stretching mechanism and stretched together with the two pressing sleeves of the second fabric stretching mechanism, and drive the two pressing sleeves to move to stretch this part of the fabric, thereby realizing continuous stretching of the fabric, so that the fabric can be stretched to the required size, so as to improve the quality of the subsequent shaping of the fabric.

[0145] Subsequently, the first and second steps are repeated to perform a secondary continuous stretching operation on the fabric that subsequently enters the fabric stretching device.

[0146] During this process, when the fabric moves, there is always a fabric stretching mechanism that can clamp the fabric and guide the fabric to move forward through the rotating support shaft 1 to improve the smoothness of the fabric movement. At the same time, another fabric stretching mechanism can perform the reset operation of the pressing sleeve. In this way, on the one hand, it will not cause excessive top pressure restrictions on the fabric, thereby hindering the movement of the fabric and affecting the fabric stretching effect. On the other hand, there is no need to reserve additional reset time for the pressing sleeve, and the fabric can be stretched continuously, and the overall stretching efficiency is higher.

[0147] Of course, during the alternating operation of the two fabric stretching mechanisms, a period of time is allowed during which the two fabric stretching mechanisms clamp the fabric at the same time to ensure that the alternating clamping of the fabric can be carried out more smoothly, and to avoid the possibility of the fabric being offset or stacked during movement due to the fact that both fabric stretching mechanisms do not clamp the fabric during the alternating operation.

[0148] Furthermore, the need for multiple stretching may be taken into consideration, or multiple fabrics a may be stretched synchronously.

[0149] As attached Figure 2 , Attachment Figure 9 As shown, the setting machine body 8 is adapted to the fabric sheathing part and is provided with two upper and lower spaced pressing devices; so that when the fabric sheathing device is placed in the setting area, the upper and lower pressing devices can respectively provide a top pressure effect on the tubular fabric sheathed on the outer periphery of the fabric sheathing part, so that one fabric sheathing part can form a fabric stretching mechanism with the two pressing devices respectively, that is, a fabric sheathing part and the one located above it form a fabric stretching mechanism at the same time, the fabric sheathing part also forms a fabric stretching mechanism with the one located below it.

[0150] When the fabric wrapping device includes two fabric wrapping parts spaced apart in the transverse direction, the setting machine body 8 is adapted to be provided with two pressing devices spaced apart in the upper and lower directions to match each fabric wrapping part.

[0151] Continuing the above description of the first fabric stretching mechanism and the second fabric stretching mechanism. Figure 9 As shown, a twisting shaft 3 is arranged at intervals below the support shaft 1 of the first fabric stretching mechanism, and the twisting shaft 3 is connected to a twisting shaft driving device 4 that provides rotational force to it, and the twisting shaft 3 is linked to a pressing component 5 that rotates with the twisting shaft 3 and approaches or moves away from the support shaft 1 in the first fabric stretching mechanism; the twisting shaft driving device 4 can be the twisting shaft driving device 4 in the first fabric stretching mechanism, so that a twisting shaft driving device 4 can synchronously drive the upper and lower twisting shafts 3 to rotate. The specific transmission connection structure is described above and will not be described in detail here.

[0152] The support shaft 1 of the second fabric stretching mechanism can also be provided with a twisting shaft 3 at intervals below. The twisting shaft 3 is connected to a twisting shaft driving device 4 that provides rotational force to it, and the twisting shaft 3 is linked to: a pressing component 5 that rotates with the twisting shaft 3 and approaches or moves away from the support shaft 1 in the second fabric stretching mechanism; the twisting shaft driving device 4 can be the twisting shaft driving device 4 in the second fabric stretching mechanism, so that a twisting shaft driving device 4 can synchronously drive the upper and lower twisting shafts 3 to rotate. The specific transmission connection structure is described above and will not be described in detail here.
