Description

Technical Field

[0001] The invention relates to the field of clothing production, in particular to a multi-layer fabric composite hot pressing device and method. Background Art

[0002] In the clothing production process, after the cut pieces are accurately cut, they need to be laminated in multiple layers (two layers, three layers or more). When two layers of fabric are laminated, they need to be accurately aligned. Due to the soft and deformable nature of clothing fabrics, it is very difficult to align the pieces, especially for adhesive fabrics. When laminating, the fabrics are deformed due to excessive pressure, making lamination very difficult. In addition, when laminating multiple layers, such as laminating two layers and then the third layer, hot pressing is required after the two layers are laminated. There are many processes. Currently, there is no composite hot pressing device that can both quickly and accurately laminate and quickly and conveniently hot press. Summary of the invention

[0038] like Figures 1 to 5 The multi-layer fabric composite hot pressing device shown includes a first adsorption mechanism 1, a second adsorption mechanism, a rotating and lifting mechanism and a heating mechanism 9.

[0039] The first adsorption mechanism 1 includes a first adsorption plate 11 and a first adsorption cavity arranged on the first adsorption plate 11. The first adsorption plate 11 and the first adsorption cavity surround each other to form a closed hollow cavity, which is used to communicate with a vacuum device. The first adsorption plate 11 is provided with an opening connected to the first adsorption cavity.

[0040] The second adsorption mechanism includes a second adsorption plate 21 and a second adsorption cavity arranged on the second adsorption plate 21. The second adsorption plate 21 and the second adsorption cavity surround each other to form a closed hollow cavity, which is used to communicate with the vacuum device. The second adsorption plate 21 is provided with an opening connected to the second adsorption cavity.

[0041] The first adsorption mechanism rotates relative to the second adsorption mechanism by rotating the lifting mechanism. When the first adsorption mechanism rotates to the point where the first adsorption plate is opposite to the second adsorption plate, the first adsorption mechanism can move in the up and down directions relative to the second adsorption mechanism, thereby adjusting the distance between the first adsorption plate and the second adsorption plate.

[0042] The first adsorption chamber and the second adsorption chamber are both composed of a composite plate and a connecting frame. The connecting frame is annular and perpendicular to the composite plate. The connecting frame is connected to the composite plate and surrounds a storage space with an opening at one end. The first adsorption plate 11 and the second adsorption plate 21 are respectively arranged on the side of the first adsorption chamber and the second adsorption chamber with an opening. The first adsorption plate 11, the composite plate and the connecting frame form a closed first adsorption chamber with a hollow space. The second adsorption plate 21, the composite plate and the connecting frame form a closed first adsorption chamber with a hollow space.

[0043] The first adsorption plate 11 and the second adsorption plate 21 are both horizontal planes, which are convenient for placing fabrics thereon.

[0044] During vacuuming, the first adsorption chamber and the second adsorption chamber are in a vacuum state, and the first adsorption plate 11 and the second adsorption plate 21 can respectively generate suction to adsorb the fabrics thereon; when the first adsorption chamber and the second adsorption chamber are in a vacuum-breaking state, the first adsorption chamber and the second adsorption chamber are connected to the atmosphere, the vacuum suction is broken, and the fabrics on the first adsorption plate 11 are detached.

[0045] The structure of the rotating and lifting mechanism is as follows: it includes a rotating shaft 3 and a lifting shaft 4, the lifting shaft 4 is connected to the rotating shaft 3, the rotating shaft 3 extends along a first direction, the lifting shaft 4 extends along a second direction, the first direction is perpendicular to the second direction, the first adsorption plate can rotate around the rotating shaft 3 (the rotating shaft 3 itself will not rotate around its own axis), and the lifting shaft 4 can move in its axial direction relative to the second adsorption plate.

[0046] The device has an initial state and a composite state. In the initial state, the first adsorption mechanism is far away from the second adsorption mechanism, and the horizontal plane of the first adsorption plate 11 is higher than the horizontal plane of the second adsorption plate 21. In the composite state, the first adsorption plate is located directly above the second adsorption plate. When the device is transformed from the initial state to the composite state, the rotating shaft 3 moves upward. When the device is transformed from the second state to the initial state, the rotating shaft 3 moves downward. That is, when the first adsorption mechanism 1 rotates, the lifting shaft 4 moves up and down relative to the second connecting part 22.

[0047] A first connection part 12 is arranged on the first adsorption chamber. The first connection part 12 is arranged on one side of the first adsorption chamber or the first adsorption plate 11 and extends outward. The rotating shaft 3 is arranged on the first connection part 12. A plurality of first connection parts 12 can be arranged. The plurality of first connection parts 12 are arranged along the first direction. A gap is maintained between each adjacent two first connection parts 12. The rotating shaft 3 can pass through the plurality of first connection parts 12 at the same time.

[0048] A second connecting part 22 is arranged on the second adsorption chamber. The second connecting part 22 is arranged on one side of the second adsorption chamber or the second adsorption plate 21 and extends outward. The first connecting part 12 and the second connecting part 22 are located on the same side of the device. A plurality of second connecting parts 22 are arranged. The plurality of second connecting parts 22 are arranged along the second direction. A lifting shaft 4 is arranged on each second connecting part 22.

[0049] When the device is in the initial state and the first adsorption chamber and the second adsorption chamber are in a vacuum state, the fabric is adsorbed on the first adsorption plate 11 and the second adsorption plate 21; when the device is in the composite state and the first adsorption chamber and the second adsorption chamber are in a broken vacuum state, the fabric on the first adsorption plate 11 detaches and falls to the fabric on the second adsorption plate 21 to form a composite fabric.

[0050] The heating mechanism 9 is used to heat-press the fabric on the second adsorption plate 21 .

[0051] The first connecting portion 12 and the second connecting portion 22 are both provided with openings, the rotating shaft 3 is inserted through the opening of the first connecting portion 12 , and the lifting shaft 4 is inserted through the opening of the second connecting portion 22 .

[0052] The second connecting portion 22 is provided with a guide hole extending along the second direction. A shaft sleeve 23 is provided in the guide hole. The lifting shaft 4 is provided in the shaft sleeve 23 and can move axially along the guide hole.

[0053] A limiter is provided at one end of the lifting shaft 4 away from the rotating shaft 3, and the limiter is used to limit the lifting shaft 4 from being separated from the guide hole, and the limiter is a sleeve body sleeved outside the lifting shaft 4. The lifting shaft 4 is fixedly connected to the rotating shaft 3 by a fastener, and the fastener is close to the upper end of the lifting shaft 4, and the fastener is a bolt and nut assembly or a pin.

[0054] A fixing plate 6 is arranged outside the first adsorption chamber, and the fixing plate 6 is a flat plate. A support rod 7 is arranged outside the second adsorption chamber, and the extension direction of the support rod 7 is consistent with the extension direction of the lifting shaft 4. The fixing plate 6 and the support rod 7 are located on the same side of the device.

[0055] A support plate is disposed on one side of the second adsorption chamber. The fixing plate 6 and the support plate are located on the same side of the device. A guide hole for the support rod 7 to pass through is opened on the support plate.

[0056] The device also includes a driving component 8, which is connected to the support rod 7 and is used to drive the support rod 7 to move up and down relative to the second adsorption chamber. The driving shaft of the driving component 8 is connected to the support rod 7. The driving component 8 is a cylinder or a motor. The driving component 8 is fixedly arranged on one side of the second adsorption chamber. A mounting plate is arranged on one side of the second adsorption chamber, and a guide hole is opened on the mounting plate for the support rod 7 to pass through.

[0057] There are multiple support rods 7, which are distributed around the second adsorption chamber. Correspondingly, there are multiple fixing plates, which are distributed around the first adsorption chamber. There are multiple driving components 8, which can ensure the stability of the two fabrics when they are fitted together.

[0058] When the device is in a composite state, the first adsorption plate 11 is located directly above the second adsorption plate 21 and the first adsorption plate 11 is parallel to the second adsorption plate 21 (the fabric on the first adsorption plate 11 is parallel to the fabric on the second adsorption plate 21), and the fixed plate 6 is against the support rod 7 to maintain a gap between the first adsorption plate 11 and the second adsorption plate 21, that is, a gap is maintained between the fabric on the first adsorption plate 11 and the fabric on the second adsorption plate 21, and there is solid glue (without fluidity) or viscous glue on the fabric on the first adsorption plate 11, and the glue has a certain thickness, which can prevent the glue from directly contacting the fabric on the second adsorption plate 21. If the fabric on the first adsorption plate 11 is in direct contact with the fabric on the second adsorption plate 21 during rotation, the two fabrics will be deformed after being composited due to excessive pressure and soft fabrics. Then the support rod 7 moves downward, and the first adsorption mechanism 1 moves downward until the fabric on the first adsorption plate 11 is fitted with the fabric on the second adsorption plate 21, and then the vacuum is broken, and the fabric on the first adsorption plate 11 is separated from the first adsorption plate 11, and the two fabrics are composited together. At this time, the composite fabric can be accurately fitted and will not be deformed. And when the thickness of the fabric or glue increases, because a gap is maintained between the fabric on the first adsorption plate 11 and the fabric on the second adsorption plate 21, it can also prevent the fabric glue on the first adsorption plate 11 from directly contacting the fabric on the second adsorption plate 21 when the first adsorption plate 11 and the second adsorption plate 21 are relative and parallel, providing a buffer space. After that, the first adsorption mechanism 1 moves downward, and the fabric on the first adsorption plate 11 and the fabric on the second adsorption plate 21 are always parallel until the fabric on the first adsorption plate 11 and the fabric on the second adsorption plate 21 are attached to each other and then the vacuum is broken.

[0059] When in the composite state, the support rod 7 is against the fixed plate, and the distance between the first adsorption plate and the second adsorption plate in the composite state can be adjusted by adjusting the support rod, so as to adapt to different thicknesses of glue and be suitable for fabrics and glue layers of different thicknesses.

[0060] When the first adsorption mechanism 1 is converted from the initial state to the composite state, the first adsorption mechanism 1 moves around the rotating shaft 3. When it hits the support rod 7, the entire first adsorption mechanism 1 takes the support rod 7 as the fixed point, and the lifting shaft 4 continues to perform a vertical upward movement while continuing to rotate around the rotating shaft 3 until the first adsorption plate 11 is located directly above the second adsorption plate 21 and the two are parallel. Then the support rod 7 descends, and then the lifting shaft 4 moves downward relative to the second adsorption chamber. The first adsorption mechanism 1 is pressed down by its own weight, or the operator manually assists in pressing down to make the first adsorption mechanism 1 descend until the fabric on the first adsorption plate 11 is in contact with the fabric on the second adsorption plate 21. At this time, the vacuum is broken again, and the vacuum extraction device (vacuum fan) is turned off at the same time. The fabric on the first adsorption plate 11 is separated from the first adsorption plate 11 and is in contact with the fabric on the second adsorption plate 21.

[0061] The heating mechanism 9 includes a heating plate 91, a heating component for heating the heating plate 91, and a moving assembly for driving the heating mechanism 9 to move along the length direction of the first adsorption plate 11 and the second adsorption plate 21. When heating, the heating plate 91 is located directly above the second adsorption plate 21, and the length direction of the first adsorption plate 11 and the second adsorption plate 21 moves in the extension direction of the rotating shaft 3. When heating is required, the heating mechanism 9 moves to the second adsorption mechanism, and when not heating, the heating mechanism 9 leaves the second adsorption mechanism. The heating plate 91 is a horizontal plate.

[0062] The first adsorption chamber and the second adsorption chamber are both provided with ventilation tubes 5, which are in communication with the first adsorption chamber and the second adsorption chamber and are in communication with the vacuum device. The ventilation tubes 5 extend outward from the first adsorption chamber and the second adsorption chamber, and are in the shape of a hollow cylinder. The first adsorption mechanism 1 and the second adsorption mechanism are arranged on the workbench through the support rod 7, and a gap is maintained between the bottom of the lifting shaft 4 and the workbench.

[0063] A plurality of first adsorption mechanisms 1 and second adsorption mechanisms can be provided to produce a plurality of composite fabrics at the same time, thereby improving processing efficiency.

[0064] The fabric on the first adsorption plate 11 and the fabric on the second adsorption plate 21 can be of the same size or the same material. The placement position of the fabric on the first adsorption plate 11 and the placement position of the fabric on the second adsorption plate 21 have been determined in advance. When the two fabrics are compounded, the two identical fabrics can be precisely compounded together.

[0065] In order to better break the vacuum, ventilation pipes are provided in the first adsorption chamber and the second adsorption chamber. The ventilation pipes have an air outlet end. The air outlet end of the ventilation pipe in the first adsorption chamber is connected with the first adsorption chamber, and the air outlet end of the ventilation pipe in the second adsorption chamber is connected with the second adsorption chamber. The ventilation pipe is provided with a valve for connecting with an external ventilation component. When the first adsorption chamber and the second adsorption chamber are in a vacuum state, the valve is closed; when the first adsorption chamber and the second adsorption chamber are in a vacuum-breaking state, the valve is opened, and appropriate air pressure is injected into the first adsorption chamber and the second adsorption chamber through the ventilation pipe, instead of being directly connected to the atmosphere. The vacuum breaking speed is fast and stable. For example, the vertical fall of the fabric on the first adsorption plate 11 is more stable.

[0066] See also Figure 5 The vent pipe includes a first vent pipe and a second vent pipe which are arranged opposite to each other, and a connecting pipe 24 which connects the first vent pipe and the second vent pipe. The first vent pipe is perpendicular to the connecting pipe 24, and the second vent pipe is perpendicular to the connecting pipe 24. The valve is arranged on the connecting pipe 24. The first vent pipe, the connecting pipe 24, and the second vent pipe are distributed at the inner edges of the first adsorption chamber and the second adsorption chamber. The injected air pressure is uniform in the adsorption chamber, and the vacuum breaking is more stable. The adsorption chamber of the adsorption chamber is provided with an installation groove 10 for placing the first vent pipe and the second vent pipe.

[0067] Alternatively, a vacuum is generated and broken by a vacuum breaking assembly, the vacuum breaking assembly comprising a housing and a sealing assembly, see Figures 6 to 9 The shell includes a first shell 13 and a second shell 14 . The first shell 13 and the second shell 14 are separated by a partition 15 arranged inside the shell. There is a hollow space in the first shell 13 and there is a hollow space in the second shell 14 .

[0068] The partition 15 is provided with a through hole; the first shell 13 is provided with a first opening 16 and a second opening 17, the first opening 16 is connected to a vacuum pump 26, and the vacuum pump 26 is used to extract the air in the shell. The second opening 17 is connected to an adsorption cavity with a hollow space (the object to be vacuumed or broken); the second shell 14 is provided with a third opening 18 connected to the atmosphere, and the second shell 14 is always connected to the atmosphere.

[0069] The structure of the shell is as follows: it includes a first plate 22, an annular side plate, and a second plate. The first plate 22 is arranged opposite to the second plate. The annular side plate is connected between the first plate 22 and the second plate and surrounds a chamber with a hollow space inside. One end of the partition 15 is connected to the first plate 22, and the other end of the partition 15 is connected to the second plate. The partition 15 separates the shell into an independent first shell 13 and a second shell 14. When the through hole on the partition 15 is blocked, the first shell 13 and the second shell 14 are not connected; when the through hole on the partition 15 is not blocked, the first shell 13 and the second shell 14 are connected through the through hole on the partition 15.

[0070] The first opening 16 is formed at a position of the first plate 22 or the second plate corresponding to the first shell 13 , and the second opening 17 is formed at a position of the annular side plate corresponding to the second shell 14 .

[0071] When the cross section of the annular side plate is square, the shell is a cube, and the first shell 13 and the second shell 14 are both cubes; when the cross section of the annular side plate is circular, the cross section of the first shell 13 and the second shell 14 can be semicircular.

[0072] The blocking assembly includes a blocking plate 19 and a guide rod 20. The blocking plate 19 is located in the first shell 13. The blocking plate 19 is used to block the through hole of the partition 15 or the second opening 17 of the first shell 13. The surface area of ​​the blocking plate 19 is greater than or equal to the cross-sectional area of ​​the through hole of the partition 15. When the surface area of ​​the blocking plate 19 is greater than the cross-sectional area of ​​the through hole of the partition 15, the blocking plate 19 is outside the through hole and can block the through hole.

The surface area of ​​the blocking plate 19 is greater than or equal to the cross-sectional area of ​​the second opening 17 of the first shell 13. When the surface area of ​​the blocking plate 19 is greater than the cross-sectional area of ​​the through hole of the second opening 17, the blocking plate 19 is outside the through hole and can block the second opening 17. When the surface area of ​​the blocking plate 19 is equal to or equal to the cross-sectional area of ​​the second opening 17, the blocking plate 19 is inside the second opening 17 and can block the second opening 17.

[0073] The guide rod 20 is fixedly connected to the blocking plate 19, and the guide rod 20 can move in the housing to drive the blocking plate 19 to move. Figure 4 , Figure 5 One end of the guide rod 20 away from the blocking plate 19 passes through the through hole of the partition plate 15 and can move within the first shell 13 and the second shell 14.

[0074] When the adsorption chamber is evacuated, the blocking plate 19 blocks the through hole of the partition 15, the first shell 13 is closed, the first shell 13 is not connected to the second shell 14, the passage to the atmosphere is blocked, and vacuum adsorption pressure is generated; when the vacuum is broken, the blocking plate 19 blocks the second opening 17 of the first shell 13. At this time, the through hole of the partition 15 is opened, and the first shell 13 is connected to the second shell 14 through the through hole of the partition 15 and the third opening 18 on the second shell 14, that is, it is connected to the atmosphere, and no vacuum power is generated, so the vacuum can be broken.

[0075] The device can generate a large suction force, can realize the rapid exchange of vacuum and vacuum breaking actions, and can maintain the balance of suction force to better laminate the fabrics.

[0076] The device further comprises a moving driving component 25, which is arranged outside the shell and connected to one end of the guide rod 20 away from the blocking plate 19. The moving driving component 25 is used to drive the blocking assembly to move in the horizontal direction.

[0077] The mobile driving component 25 is a cylinder or a motor, and the driving shaft of the mobile driving component 25 is connected to the guide rod 20. The mobile driving component 25 can be a cylinder or a motor. During the vacuum pumping and vacuum breaking process, the motor or cylinder can be driven all the time. The movement of the sealing component can be controlled by operating the start and stop buttons without frequently starting the motor, that is, the motor can continue to operate.

[0078] The second housing 14 is provided with an opening, and the driving shaft of the moving driving component 25 passes through the opening and is connected to the guide rod 20 located in the housing.

[0079] The through-hole cross-sections of the blocking plate 19 and the partition plate 15 are circular or polygonal, the cross-section of the annular side plate is square or circular, and the shell is in the shape of a cube or a cylinder.

[0080] The first adsorption chamber, the second adsorption chamber and the second opening 17 of the first shell 13 are connected through a connecting pipe, and the connecting pipe is a soft air pipe.

[0081] A multi-layer fabric composite hot pressing method, the method adopts the multi-layer fabric composite hot pressing device, and comprises the following steps:

[0082] S1. The device is in the initial state. A fabric is placed on the first adsorption plate 11 and adsorbed. Another fabric is placed on the second adsorption plate 21 and adsorbed. The first adsorption mechanism 1 is rotated until the device is in the composite state. Specifically, when the first adsorption mechanism 1 is converted from the initial state to the composite state, the first adsorption mechanism 1 moves around the rotating shaft 3 until the first adsorption plate abuts against the support rod 7. At this time, the first adsorption plate 11 is located directly above the second adsorption plate 21 and the two are parallel.

[0083] S2, move the support rod 7 downward, and the first adsorption mechanism 1 downward, until the fabric on the first adsorption plate 11 is in contact with the fabric on the second adsorption plate 21, and then break the vacuum, release the fabric on the first adsorption plate 11, and the fabric falls onto the fabric on the second adsorption plate 21, and the first adsorption mechanism 1 returns to the initial state, and starts the heating mechanism 9 to heat the fabric to obtain a composite fabric;

[0084] S3, repeat steps S1 and S2 to obtain a multi-layer composite fabric.

[0085] For example, a composite hot pressing method for preparing a three-layer composite fabric includes the following steps:

[0086] S1, the device is in the initial state, a fabric is placed on the first adsorption plate 11 and adsorbed, another fabric is placed on the second adsorption plate 21 and adsorbed, and the first adsorption mechanism 1 is rotated until the device is in the composite state;

[0087] S2, the first adsorption plate 11 releases the fabric thereon, and the fabric falls onto the fabric on the second adsorption plate 21, the first adsorption mechanism 1 returns to the initial state, and the heating mechanism 9 is started to heat the fabric to obtain a composite fabric;

[0088] S3, placing another fabric on the first adsorption plate 11 and adsorbing the fabric, and rotating the first adsorption mechanism 1 until the device is in a composite state;

[0089] S4, the first adsorption plate 11 releases the fabric thereon, and the fabric moves down to the fabric that has been heated in step S2, the first adsorption mechanism 1 returns to its initial state, and the heating mechanism 9 is started to heat the fabric to obtain a new composite fabric.

[0090] If more than three layers of composite fabric are to be prepared, the above composite hot pressing method can be referred to, which is convenient and efficient to operate.
