Abstract
Description
Technical Field
[0001] This application relates to the field of automated sewing machine technology, and in particular to a quick-change air tube device and a sewing machine. Background Technology
[0002] The sewing industry is becoming increasingly automated, with automated clamps used to hold fabric in place and work with sewing machine needles to complete automatic sewing. In traditional techniques, automated clamps typically only have a clamping function; the fabric folding operation still relies on manual intervention. This not only increases human intervention and reduces the overall level of automation but also makes it difficult to ensure the consistency of folding angles and positions, affecting sewing quality.
[0003] To improve the automation of the sewing process, existing technologies add cylinders to automated fixtures. The extension and retraction of these cylinders drive the fixtures or auxiliary components to automatically fold the fabric, thus reducing manual intervention. However, since the added cylinders are usually directly mounted on the automated fixtures, their air hoses are susceptible to bending and pulling caused by the horizontal movement of the fixtures, leading to wear and tear over time. Furthermore, when the automated fixtures are replaced, the air hoses also need to be replaced, making the disassembly and reinstallation process cumbersome and increasing maintenance difficulty and time costs. Utility Model Content
[0004] Therefore, it is necessary to provide a quick-change trachea device that can solve the above problems.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] A quick-change air hose device is installed on the frame of a sewing template machine and is used for limiting and quickly changing air hoses. The air hoses are connected to a solenoid valve and a cylinder located on an automated fixture. The quick-change air hose device includes:
[0007] A movable guide rail is mounted on the frame and extends along a first direction, and is capable of moving along a second direction;
[0008] The pressure frame is positioned on the movable guide rail and is movable along the first direction on the movable guide rail;
[0009] A quick-change air tube plate is provided on the pressure frame, and multiple air inlets are provided on one side, and multiple air outlets corresponding to the air inlets are provided on the other side. The air outlets are used to connect to the cylinders on the automated fixture.
[0010] The follow-up limiting component is fixedly mounted on the frame at one end and mounted on the pressure frame at the other end;
[0011] The first direction and the second direction are set at an angle. One end of the air pipe is connected to the solenoid valve, and the other end passes through the follow-up limiting component and is connected to the air inlet. The follow-up limiting component has a constant total length and can move with the movement of the moving guide rail and the pressure frame.
[0012] Understandably, this application uses a quick-change air pipe plate and a follow-up limiting component to connect the air pipe of the cylinder on the automated fixture via the quick-change air pipe plate as an interface. When the automated fixture needs to be replaced, only this section of the air pipe needs to be replaced, without the need for complete disassembly and reinstallation. Moreover, the follow-up limiting component limits the air pipes connected to the solenoid valve and the quick-change air pipe plate respectively. As the quick-change air pipe plate moves with the automated fixture, the air pipe deforms within the follow-up limiting component and will not be bent or pulled arbitrarily. This reduces air pipe wear, thereby increasing the service life of the air pipe and reducing maintenance difficulty and time costs.
[0013] In one embodiment, the follower limiting component includes a first follower limiting member and a second follower limiting member. The first follower limiting member has a first air pipe inlet end and a first air pipe outlet end formed at its two ends, respectively. The first air pipe inlet end is fixedly disposed on the frame, and the first air pipe outlet end is fixedly disposed on the moving guide rail. The second follower limiting member has a second air pipe inlet end and a second air pipe outlet end formed at its two ends, respectively. The second air pipe inlet end is fixedly disposed on the moving guide rail near the first air pipe outlet end, and the second air pipe outlet end is fixedly disposed on the pressure frame.
[0014] Understandably, by setting a first follower limiter and a second follower limiter, the first follower limiter can deform in coordination with the displacement of the moving guide rail along the first direction on the frame, and the second follower limiter can deform in coordination with the displacement of the pressure frame along the first direction on the moving guide rail. The air tube passes through the first follower limiter and the second follower limiter in sequence. The air tube located at the first follower limiter can deform with the first follower limiter in the first direction, and the air tube located at the second follower limiter can deform with the second follower limiter in the second direction. This makes it less likely that the air tube connected to the quick-change plate will be pulled when the quick-change plate moves in the first and second directions, thereby reducing air tube wear and increasing the service life of the air tube.
[0015] In one embodiment, the first direction and the second direction are located in a first plane, the first follower limiting member is disposed along the first plane and is movable within the first plane;
[0016] And / or, the first direction is also located in a second plane intersecting the first plane, the second follower limiting member is disposed along the second plane and is movable within the second plane.
[0017] In one embodiment, the second plane is arranged perpendicular to the first plane.
[0018] In one embodiment, the first follower limiting member is disposed on one side of the moving guide rail along the second direction, the pressure frame is disposed on the other side of the moving guide rail along the second direction, and the air tube quick-change plate is disposed on the side of the pressure frame along the second plane close to the second follower limiting member.
[0019] In one embodiment, the first follower limiter and / or the second follower limiter are configured as a cable chain.
[0020] In one embodiment, the quick-change trachea device further includes a connecting frame, one end of which is connected to the movable guide rail, and the other end of which is connected to the second trachea inlet end of the second follow-up limiting member;
[0021] The inlet end of the second air tube is connected to the movable guide rail via the connecting frame.
[0022] In one embodiment, the tracheal quick-change plate is configured as a rectangle.
[0023] This application also provides the following technical solutions:
[0024] A sewing machine includes a frame, an automated clamp, a solenoid valve, an air hose, and an air hose quick-change device as described in any of the above embodiments.
[0025] In one embodiment, the automated clamp is fixed to the pressure frame of the endotracheal quick-change device and is movable with the pressure frame of the endotracheal quick-change device.
[0026] Compared with existing technologies, the trachea quick-change device uses a trachea quick-change plate and a follow-up limiting component to connect the trachea to the cylinder of the automated fixture. When the automated fixture needs to be replaced, only this section of the trachea needs to be replaced, without the need for complete disassembly and reinstallation. Moreover, the follow-up limiting component limits the trachea on the other side of the trachea quick-change plate. As the automated fixture moves, the trachea deforms within the follow-up limiting component, preventing it from being bent or pulled arbitrarily. This reduces trachea wear, increases the service life of the trachea, and reduces maintenance difficulty and time costs. Attached Figure Description

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0041] Please see Figures 1 to 5 This application provides a quick-change air hose device 100, which is applied to a sewing machine 200. The sewing machine 200 also includes a frame 201, an automated clamp (not shown), a solenoid valve (not shown), and an air hose (not shown). The quick-change air hose device 100, the automated clamp, and the solenoid valve are all mounted on the frame 201. A cylinder is installed on the automated clamp, and the cylinder is connected to the solenoid valve via the air hose. When the solenoid valve is open, air flows through the air hose; when the solenoid valve is closed, air does not flow through the air hose. This quick-change air hose device 100 is used for limiting and quickly replacing the air hose.
[0042] Specifically, the trachea quick-change device 100 includes a movable guide rail 10, a pressure frame 20, a trachea quick-change plate 30, and a follow-up limiting assembly 40. The movable guide rail 10 is mounted on the frame 201 and extends along a first direction x, and is movable along a second direction y. The pressure frame 20 is limited by the movable guide rail 10 and is movable along the first direction x on the movable guide rail 10. The trachea quick-change plate 30 is mounted on the pressure frame 20, and has multiple air inlets 31 on one side and an air inlet 32 on the other side. 1. Multiple air outlets 32 are provided for connecting to cylinders on the automated fixture; one end of the follow-up limiting component 40 is fixedly set on the frame 201, and the other end is set on the pressure frame 20; wherein, the first direction x and the second direction y are set at an angle, one end of the air pipe is connected to the solenoid valve, and the other end passes through the follow-up limiting component 40 and is connected to the air inlet 31. The total length of the follow-up limiting component 40 remains unchanged and can move with the movement of the moving guide rail 10 and the pressure frame 20. Thus, by setting up a quick-change plate 30 for the air pipe and a follow-up limiting component 40, the quick-change plate 30 is used as an interface to connect with the air pipe of the cylinder on the automated fixture. When the automated fixture needs to be replaced, only this section of the air pipe needs to be replaced, without the need for complete disassembly and reinstallation. Moreover, the follow-up limiting component 40 limits the air pipes connected to the solenoid valve and the quick-change plate 30 respectively. As the quick-change plate 30 moves with the automated fixture, the air pipe deforms within the follow-up limiting component 40 and will not be bent or pulled at will. This reduces air pipe wear, thereby increasing the service life of the air pipe and reducing maintenance difficulty and time costs.
[0043] like Figures 1 to 3 As shown, the movable guide rail 10 is mounted on the frame 201 and can move on the frame 201 along the second direction y. The movable guide rail 10 is provided with a guide groove 11 extending along the first direction x. The pressure frame 20 is limited to the movable guide rail 10 and can move along the guide groove 11 in the first direction x.
[0044] like Figure 3 As shown, the pressure frame 20 is provided with a positioning part 21, a fixing part 22 and a fixing reinforcement part 23. The positioning part 21 is used for the installation and positioning of the automated fixture, and the fixing part 22 is used for fixing the automated fixture. Since the automated fixture for installing the cylinder is relatively heavy, this application also provides a fixing reinforcement part 23 to strengthen the fixing of the automated fixture.
[0045] In one embodiment, the positioning part 21 is configured as a positioning protrusion, the fixing part 22 is configured as a fixing rod and a fixing hole, and the fixing reinforcement part 23 is configured as a connecting block and a cylinder with an output shaft extending into the connecting block. Correspondingly, the automated fixture is provided with a positioning groove, a clamping hole, and a connecting shaft to cooperate in fixing the automated fixture. Specifically, the automatic fixture is first positioned using the positioning groove and the positioning protrusion. Then, the clamping rod passes through the clamping hole and the fixing hole to fix the automatic fixture to the pressure frame 20. Finally, the connecting shaft passes through the connecting block, and the output shaft abuts against the connecting shaft to limit its movement, thus fixing the automated fixture. It should be noted that in other embodiments, other existing methods can also be used to fix the automated fixture, which will not be described in detail here.
[0046] In one embodiment, the quick-change plate 30 for the air tube is configured in a rectangular shape. By configuring the quick-change plate 30 in a rectangular shape, it avoids obstructing other components of the frame 201 and does not affect the movement of the automated fixture. Here, the number of air inlets 31 can be six, ten, fourteen, twenty, twenty-four, etc., and the number of air outlets 32 is the same as the number of air inlets 31, with each outlet and inlet 31 corresponding to the other, and the corresponding air outlets 32 and air inlets 31 are interconnected.
[0047] Here, the quick-change tubing assembly can be connected to the pressure frame 20 by means of snap-fit, bolts, pins, etc.
[0048] like Figures 1 to 4As shown, the follower limiting component 40 includes a first follower limiting member 41 and a second follower limiting member 42. The first follower limiting member 41 forms a first air pipe inlet end 411 and a first air pipe outlet end 412 at its two ends. The first air pipe inlet end 411 is fixedly mounted on the frame 201, and the first air pipe outlet end 412 is fixedly mounted on the moving guide rail 10. The second follower limiting member 42 forms a second air pipe inlet end 421 and a second air pipe outlet end 422 at its two ends. The second air pipe inlet end 421 is fixedly mounted on the moving guide rail 10 near the first air pipe outlet end 412, and the second air pipe outlet end 422 is fixedly mounted on the pressure frame 20. Thus, by setting the first follower limiter 41 and the second follower limiter 42, the first follower limiter 41 can deform in coordination with the displacement of the moving guide rail 10 along the first direction x on the frame 201, and the second follower limiter 42 can deform in coordination with the displacement of the pressure frame 20 along the first direction x on the moving guide rail 10. The air tube passes through the first follower limiter 41 and the second follower limiter 42 in sequence. The air tube located at the first follower limiter 41 can deform in the first direction x with the first follower limiter 41, and the air tube located at the second follower limiter 42 can deform in the second direction y with the second follower limiter 42. This makes it less likely that the air tube connected to the quick-change plate 30 will be pulled when it moves in the first direction x and the second direction y, thereby reducing air tube wear and improving the service life of the air tube.
[0049] Here, the ends of the first follower limit member 41 and the second follower limit member 42 can be connected by bolts, pins, buckles, etc.
[0050] In one embodiment, the first direction x and the second direction y are located in a first plane, and the first follower limiting member 41 is disposed along the first plane and is movable within the first plane.
[0051] In one embodiment, the first direction x is also located in a second plane intersecting the first plane, and the second follower limiting member 42 is disposed along the second plane and is movable within the second plane.
[0052] In one embodiment, the second plane is arranged perpendicular to the first plane.
[0053] In this embodiment, the first plane is a horizontal plane, the second plane is a vertical plane, and the first direction x and the second direction y are also perpendicular. Thus, the movement paths of the moving guide rail 10 and the pressure frame 20 are clear, facilitating their installation and control.
[0054] like Figure 2 and Figure 4As shown, the first follower limiting member 41 is disposed on one side of the moving guide rail 10 along the second direction y, the pressure frame 20 is disposed on the other side of the moving guide rail 10 along the second direction y, and the air tube quick-change plate 30 is disposed on the side of the pressure frame 20 along the second plane close to the second follower limiting member 42.
[0055] In one embodiment, the first follower limiting member 41 and the second follower limiting member 42 are configured as a cable chain. In other embodiments, the first follower limiting member 41 and the second follower limiting member 42 may also adopt a spiral wound protective sleeve, a segmented conduit, or other structures.
[0056] In one embodiment, the trachea quick-change device 100 further includes a connecting frame 50, one end of which is connected to the moving guide rail 10, and the other end is connected to the second trachea inlet end 421 of the second follower limiting member 42. The second trachea inlet end 421 and the moving guide rail 10 are connected through the connecting frame 50.
[0057] This application also provides the following technical solutions:
[0058] A sewing machine 200, such as Figure 5 As shown, it includes a frame 201, an automated fixture, a solenoid valve, an air tube, and an air tube quick-change device 100 as in any of the above embodiments.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
