Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically to a multi-stage adjustment and conversion device for adsorbing fabric. Background Technology

[0002] Currently, most garments involve pocket processing to enhance functionality or aesthetics. The pocket processing process requires setting the pocket opening position on a workbench. The general steps are as follows: first, place the bottom layer of fabric on a template, then flip and press down the first layer strip on the template, then place the second layer of fabric. After the second layer is placed, press down the second layer strip on the template, then place the third layer of fabric and press down the third layer strip. Due to the multiple layers of fabric, the template has suction ports to hold the fabric in place and prevent the bottom layer from being dragged.

[0003] For example, Chinese patent application number 201620958726.0, published on February 15, 2017, discloses an automatic fabric feeding device for an automatic bag opening machine, including a frame and a feeding platform mounted on the frame. A sewing machine head is mounted on the feeding platform, and a feeding plate is provided on the front side of the sewing machine head with a gap between it and the feeding platform. Two baffles are vertically spaced on the feeding platform, and the two baffles are horizontally spaced to leave a gap between them and the sewing machine head. A first linear drive device is provided on the rear side of the feeding platform to drive the baffles to reciprocate linearly along the feeding direction, and a second linear drive device is provided to drive the first linear drive device and drive the two baffles to press vertically downward onto the feeding platform.

[0004] The aforementioned literature describes setting up suction holes on the feeding platform and connecting these holes to a vacuum pump via a connecting pipe. This allows the vacuum pump to directly adsorb the fabric placed on the feeding platform. However, after the fabric is placed, the adsorption process needs to be interrupted to allow the fabric to be transported before it is placed again. This requires restarting the externally connected vacuum pump. During long-term production operations, this results in frequent switching between turning the vacuum pump on and off, which can easily affect its suction performance, shorten its service life, and weaken its suction power, potentially leading to decreased stability of the adsorbed fabric. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage adjustment and conversion device for adsorbing fabric, which can avoid the frequent start-up of vacuum suction equipment for adsorbing fabric, thereby adsorbing fabric through stable suction power and extending service life.

[0006] To achieve the above objectives, a multi-stage adjustment and conversion device for adsorbing fabric is provided, which is fixed on the frame of a workbench. The device includes a housing, an opening and closing assembly one, an opening and closing assembly two, a connecting pipe one, and a connecting pipe two. The housing contains a first cavity, a second cavity, and a third cavity. The first and second cavities are located above the third cavity, respectively. The connecting pipe one communicates with the first cavity, and the connecting pipe two communicates with the third cavity. The third cavity communicates with the first and second cavities through through holes one and two, respectively. The output end of the opening and closing assembly one moves within the first cavity to adjust the opening and closing of through hole one, and the output end of the opening and closing assembly two moves within the second cavity to adjust the opening and closing of through hole two. The second cavity communicates with the outside. The housing is fixed on the frame to form a sealed cavity. The connecting pipe one is connected to an air suction port on the workbench, and the connecting pipe two is connected to an external vacuum suction device.

[0007] The above structure, after connecting pipe one to the suction hole on the worktable and connecting pipe two to the external vacuum suction device, allows the external vacuum suction device to be activated when it is necessary to adsorb the fabric set at the suction hole on the worktable. Then, the opening and closing component one is controlled to disengage from the through hole one, while the opening and closing component two is controlled to move to the through hole two, so that the third cavity is only connected to the first cavity. At this time, connecting pipe one and connecting pipe two are connected through the housing. After suction by the external vacuum suction device, the fabric set at the suction hole on the worktable can be adsorbed and fixed. Meanwhile, on the worktable... When no fabric is placed at the suction hole or the fabric does not need to be fixed temporarily, the opening and closing component one can be controlled to move to the through hole, while the opening and closing component two is controlled to disengage from the through hole two, so that the third cavity is only connected to the second cavity. At this time, the connecting pipe one and the connecting pipe two cannot be connected. Since the second cavity is connected to the outside, the external vacuum suction device can draw in the outside air. In this way, by controlling the movement of the opening and closing component one and the opening and closing component two, the fabric can be adsorbed, thereby avoiding the frequent start-up of the vacuum suction device for adsorbing the fabric, and thus adsorbing the fabric through stable suction power.

[0008] Furthermore, one side of the housing is provided with an air inlet / outlet area, and the second cavity is connected to the outside through the air inlet / outlet area. The air inlet / outlet area is provided with two or more through holes.

[0009] The above settings enable the second cavity to connect with the outside world through the air inlet and outlet areas.

[0010] Furthermore, the other side of the box is provided with a through hole four, one end of the connecting pipe one is connected to the first cavity through the through hole four, and the other end of the connecting pipe one is connected to the air intake on the workbench.

[0011] The above settings enable the air intake on the workbench to be connected to the first cavity via a connecting pipe.

[0012] Furthermore, the bottom of the box is provided with a through hole five, one end of the connecting pipe two is connected to the third cavity through the through hole five, and the other end of the connecting pipe two is connected to an external vacuum suction device.

[0013] The above settings enable the external vacuum suction equipment to connect to the third cavity via connecting pipe two.

[0014] Furthermore, the opening and closing assembly includes a driving component and a cover plate that matches the through hole. The driving component is located on the top of the housing, and the output end of the driving component extends through the top of the housing into the first cavity. A connecting component is fixedly provided on the cover plate, and the connecting component is connected to the output end of the driving component.

[0015] The above configuration facilitates the movement of the cover plate via the drive component, thereby enabling the opening and closing of the through hole and controlling whether the first cavity is connected to the third cavity.

[0016] Furthermore, the second opening and closing component includes a second driving component and a second cover plate that matches the second through hole. The second driving component is located on the top of the housing, and the output end of the second driving component extends through the top of the housing into the second cavity. A second connecting component is fixedly provided on the second cover plate, and the second connecting component is connected to the output end of the second driving component.

[0017] The above configuration facilitates the movement of the cover plate two by the drive component two, thereby enabling the opening and closing of the through hole two, and thus controlling whether the second cavity is connected to the third cavity.

[0018] Furthermore, a partition plate 1 is provided between the first cavity and the second cavity, and a partition plate 2 is provided between the first cavity, the second cavity and the third cavity. Both through holes 1 and 2 are provided on the partition plate 2.

[0019] The above configuration facilitates the separation of the first cavity from the second cavity via partition one, and also facilitates the separation of the third cavity from the first cavity and the second cavity via partition two. Attached Figure Description

The housing 1 is fixed on the frame to form a sealed cavity. A connecting pipe 1 2 is connected to the suction hole on the worktable.

[0024] One side of the housing 1 is provided with an air inlet / outlet area 18, and the second cavity 12 is connected to the outside through the air inlet / outlet area 18. The air inlet / outlet area 18 is provided with two or more through holes 3 (not shown in the figure). The other side of the housing 1 is provided with a through hole 4. The connecting pipe 1 2 is connected to the first cavity 11. In this embodiment, one end of the connecting pipe 1 2 is connected to the first cavity 11 through the through hole 4, and the other end of the connecting pipe 1 2 is connected to the air intake hole on the workbench (not shown in the figure). This allows the air intake hole on the workbench to be connected to the first cavity 11 through the connecting pipe 1 2.

[0025] The bottom of the housing 1 is provided with a through hole 5, and the connecting pipe 2 3 is connected to the third cavity 13. In this embodiment, one end of the connecting pipe 2 3 is connected to the third cavity 13 through the through hole 5, and the other end of the connecting pipe 2 3 is connected to an external vacuum suction device (not shown in the figure), so that the external vacuum suction device can be connected to the third cavity 13 through the connecting pipe 2 3.

[0026] The output end of the opening and closing component 1 moves within the first cavity 11 to adjust the opening and closing of the through hole 16. The opening and closing component 1 includes a driving component 21 and a cover plate 22 that matches the through hole 16. The driving component 21 is located at the top of the housing 1. The output end of the driving component 21 extends through the top of the housing 1 into the first cavity 11. A connecting component 23 is fixedly provided on the cover plate 22. The connecting component 23 is detachably connected to the output end of the driving component 21. In this embodiment, the connecting component 23 is a nut, the driving component 21 is a cylinder, and the output end of the driving component 21 is threaded, thereby enabling a detachable spiral connection between the connecting component 23 and the output end of the driving component 21.

[0027] The output end of the second opening and closing component moves within the second cavity 12 to adjust the opening and closing of the second through hole 17. The second opening and closing component includes a second driving component 31 and a second cover plate 32 that matches the second through hole 17. The second driving component 31 is located at the top of the housing 1. The output end of the second driving component 31 extends through the top of the housing 1 into the second cavity 12. A second connecting component 33 is fixedly provided on the second cover plate 32. The second connecting component 33 is detachably connected to the output end of the second driving component 31. In this embodiment, the second connecting component 33 is a nut, the second driving component 31 is a cylinder, and the output end of the second driving component 31 is threaded, thereby enabling the second connecting component 33 and the output end of the second driving component 31 to achieve a detachable spiral connection.

[0029] The working principle of this utility model is as follows: When it is necessary to adsorb the fabric set at the suction hole on the worktable, the external vacuum suction device is activated. Then, by controlling the operation of the first drive component, the opening and closing component 1 is disengaged from the through hole 16. At the same time, by controlling the operation of the second drive component, the opening and closing component 2 is moved to the through hole 2 17, so that the third cavity 13 is only connected to the first cavity 11. At this time, the first connecting pipe 2 and the second connecting pipe 3 are connected through the housing 1. After being suctioned by the external vacuum suction device, the fabric set at the suction hole on the worktable can be adsorbed and fixed. When no fabric is placed at the air hole or the fabric does not need to be fixed temporarily, control the opening and closing component one to move to the through hole one 16, and at the same time control the opening and closing component two to disengage from the through hole two 17, so that the third cavity 13 is only connected to the second cavity 12. At this time, the connecting pipe one 2 and the connecting pipe two 3 cannot be connected. Since the second cavity 12 is connected to the outside, the external vacuum suction device will suck in the outside air. In this way, by controlling the movement of the opening and closing component one and the opening and closing component two, the fabric can be adsorbed, thereby avoiding the frequent start of the vacuum suction device for adsorbing the fabric, and thus adsorbing the fabric through stable suction power.
