Description

Technical Field

[0001] This invention relates to the field of garment processing technology, and in particular to a lining feeding device and its method of use. Background Technology

[0002] Pants loops are commonly sewn onto the lower garments of clothing (such as trousers and skirts) to primarily secure the waistband. However, when pants loops are sewn onto the main body of the garment, the main body fabric is usually only a thin layer, making the loops susceptible to damage from the tension of the waistband during use. To improve the strength of the seam, padding (also called lining) is usually placed between the main body fabric and the pants loop. By sewing the pants loop, the main body fabric, and the padding together, the padding enhances the strength of the seam and its durability.

[0003] Existing padding typically involves automated cutting using equipment, followed by manual placement of the cut padding pieces between the corresponding body fabric and trouser loops for sewing. However, manual placement of padding is not only inefficient but also prone to inaccurate positioning due to human factors, which in turn affects the quality of the sewing process. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lining feeding device and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liner feeding device includes a liner feeding frame, on which a punching die and a punching knife corresponding to the punching die are provided. Above the punching die is a push plate that is connected to a transmission belt and can be driven to move back and forth. A feeding roller is drivenly connected to the transmission belt. A driven roller that engages with the feeding roller is installed on the liner feeding frame.

[0007] Preferably, the driven roller is mounted on the feeding frame and can be driven to move and abut against the feeding roller.

[0008] Preferably, a lifting frame is slidably mounted on the feeding frame, and the driven roller is rotatably mounted on the lifting frame and can abut against the feeding roller as the lifting frame moves.

[0009] Preferably, fixing blocks are installed on both sides of the push plate, one of which is fixed to the transmission belt, and the other is slidably connected to the slide rail of the feeding frame.

[0010] Preferably, the feeding frame is provided with a sliding plate for mounting the punching die, the push plate can move back and forth along the sliding plate, and the punching blade can move upward and pass through the punching hole of the punching die.

[0011] Preferably, the sliding plate is provided with a feeding plate corresponding to the push plate.

[0012] Preferably, a feeding channel for conveying the lining strip is provided between the punching die and the punching blade, the feeding roller and the driven roller are located on one side of the feeding channel, and a waste channel is provided on the other side of the feeding channel.

[0013] Preferably, the lining feeding frame is equipped with a guide block corresponding to the driven roller, and the guide block is provided with a limiting groove for limiting the conveying of the lining belt.

[0014] The present invention also discloses a method of using a liner feeding device, comprising:

[0015] S1. The lining strip is conveyed between the punching die and the punching knife, and the lining can be punched upward through the punching die by the punching knife;

[0016] S2. The pusher plate is driven by the transmission belt to push the lining fabric backward, and can push the lining fabric to the sewing station for sewing processing.

[0017] S3, The punching blade moves downwards away from the punching die;

[0018] S4. The driven roller is driven to move and abut against the feed roller, so that the driven roller and the feed roller press against the lining belt from above and below;

[0019] S5. The push plate is driven forward by the transmission belt to reset, and the transmission belt synchronously drives the feeding roller to rotate and cooperates with the driven roller to convey the lining belt so that the punching knife can punch out the lining again.

[0020] S6. The driven roller is driven away from the feed roller so that the lining belt on the driven roller is away from the feed roller.

[0021] Preferably, when the lining is being sewn at the sewing station, the punch cutter punches the lining upward through the punching die so that the pusher plate can be in the feeding state.

[0022] The beneficial effects of this invention are:

[0023] 1. By using a shared drive belt to drive the push plate and the feeding roller, the installation of drive components is reduced, making the structure of the equipment more compact. At the same time, the push plate automatically pushes the lining to the sewing station, so as to realize the automated, efficient and precise feeding of the lining and ensure the subsequent sewing quality of the lining.

[0024] 2. The driven roller clutch transmission cooperates with the feeding roller to transport the lining tape to be punched. When the push plate pushes the lining tape to be punched, the driven roller and the feeding roller abut against each other to transport the lining tape, so that the punching knife can punch the lining tape again. When the push plate moves in the reverse reset direction, the driven roller moves away from the feeding roller to avoid the feeding roller rotating in the reverse direction and causing the lining tape to move. This makes the lining feeding structure of the present invention more reasonable and the lining feeding efficiency higher, and also improves the efficiency of subsequent sewing processing invisibly.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] like Figures 1-6 As shown, this embodiment discloses a lining feeding device, including a lining feeding frame 1 and a cover 19 covering the outside of the lining feeding frame 1. The lining feeding frame 1 is provided with a punching die 14 and a punching blade 5 corresponding to the punching die 14. The punching die 14 and the punching blade 5 are arranged vertically at intervals, and a feeding channel 15 for conveying the lining strip is provided between the punching die 14 and the punching blade 5. The lining strip to be punched is conveyed in the feeding channel 15.

[0036] The punching blade 5 is connected to a punching assembly 51 for driving its lifting and lowering displacement. The punching assembly 51 can be a cylinder. The punching assembly 51 is mounted on the lining feeding frame 1 and the punching blade 5 is connected to its driving end. The punching assembly 51 drives the punching blade 5 to move upward to perform a punching action. Specifically, the punching blade 5 can move upward and pass through the punching hole 141 of the punching die 14 to punch out the lining on the lining strip.

[0037] Above the punching die 14 is a push plate 2 connected to the transmission belt 11 and capable of being driven to move back and forth. Specifically, the liner feeding frame 1 is provided with a sliding plate 13 for mounting the punching die 14. When the punching blade 5 punches out the liner through the punching hole 141, the punching blade 5 is flush with or slightly lower than the upper end of the sliding plate 13.

[0038] The push plate 2 is equipped with fixing blocks 21 on both sides. One of the fixing blocks 21 is fixed to the transmission belt 11, that is, the push plate 2 is connected to the transmission belt 11 through the fixing block 21. The other fixing block 21 is slidably connected to the slide rail 12 of the feeding frame 1. The slide rail 12 extends back and forth and is fixed to the feeding frame 1 so that the push plate 2 can slide back and forth along the slide rail 12.

[0039] The feeding frame 1 is equipped with a photoelectric switch 18. When the fixed block 21 moves back and forth with the push plate 2, it can correspond to the photoelectric switch 18 to detect the limit displacement of the push plate 2, thereby ensuring the reliability of the push plate 2's back and forth movement.

[0040] Furthermore, the push plate 2 can move back and forth along the sliding plate 13, that is, the push plate 2 automatically pushes the lining to the sewing station to achieve automated, efficient and precise feeding of the lining, and ensure the subsequent sewing quality of the lining. The sliding plate 13 is provided with a feeding plate 3 corresponding to the push plate 2, so that the push plate 2 can also push the lining onto the feeding plate 3, so as to realize the automated feeding action of the lining through the feeding plate 3.

[0041] Furthermore, a feeding roller 4 is connected to the transmission belt 11, and a transmission assembly 111 is installed on the feeding frame 1. The transmission assembly 111 can be a motor, and the drive end of the transmission assembly 111 is connected to the transmission belt 11 so that the transmission belt 11 can be driven to rotate in both directions. Thus, when the transmission belt 11 drives the push plate 2 to move backward, the feeding roller 4 rotates synchronously in the forward direction, and when the transmission belt 11 drives the push plate 2 to move forward, the feeding roller 4 rotates synchronously in the reverse direction.

[0042] The lining feeder 1 is equipped with a driven roller 42 that engages with the feed roller 4 via a clutch transmission. The lining strip is positioned between the feed roller 4 and the driven roller 42, with the driven roller 42 located below the feed roller 4. The driven roller 42 is mounted on the lining feeder 1 and can be driven to move and abut against the feed roller 4, thereby driving the driven roller 42 to rotate and convey the lining strip.

[0043] A lifting frame 41 is slidably mounted on the feeding frame 1. The driven roller 42 is rotatably mounted on the lifting frame 41 and can move with the lifting frame 41 to abut against the feeding roller 4. Specifically, the feeding frame 1 is equipped with a lifting assembly 411, which can be a cylinder. The driving end of the lifting assembly 411 is connected to the lifting frame 41, thereby driving the lifting frame 41 to move up and down to achieve the action of the driven roller 42 abutting against the feeding roller 4.

[0044] In this embodiment, the driven roller 42 engages with the feeding roller 4 to transport the lining strip to be punched. When the push plate 2 pushes the lining strip to be punched, the driven roller 42 rises and abuts against the feeding roller 4 to transport the lining strip, so that the punching blade 5 can punch the lining strip again to prepare for the next punching of the lining strip. When the push plate 2 moves in the reverse direction to reset, the driven roller 42 descends and moves away from the feeding roller 4 to avoid the feeding roller 4 rotating in the reverse direction and causing the lining strip to move. This makes the lining feeding structure of this embodiment more reasonable and the lining feeding efficiency higher.

[0045] Specifically, when the lining is being sewn at the sewing station, the push plate 2 reverses and resets, and the punch cutter 5 punches the lining upwards. After the sewing at the sewing station is completed, the push plate 2 can quickly push a new lining for sewing, thereby improving the efficiency of subsequent sewing processes invisibly.

[0046] Furthermore, in this embodiment, the push plate 2 and the feeding roller 4 are driven by a shared transmission belt 11, which reduces the installation of driving components, thereby making the structure of the equipment more compact and occupying less space.

[0047] The feeding roller 4 and the driven roller 42 are located on one side of the feeding channel 15. The other side of the feeding channel 15 is provided with a waste channel 17. The lining frame 1 is equipped with a guide block 16 corresponding to the driven roller 42. The guide block 16 is provided with a limiting groove 161 for limiting the conveying of the lining strip. That is, the uncrushed lining strip is limited and guided by the limiting groove 161 and conveyed between the feeding roller 4 and the driven roller 42. After passing through the feeding channel 15 between the punching die 14 and the punching knife 5, the lining strip enters the waste channel 17 (the lining strip in the waste channel 17 has been punched by the punching knife 5) and is conveyed outward through the waste channel 17.

[0048] This embodiment also discloses a method of using the lining feeding device, including:

[0049] S1. The lining strip is conveyed between the punching die 14 and the punching blade 5, and the lining can be punched upward through the punching die 14 by the punching blade 5;

[0050] S2, the pusher plate 2 is driven by the transmission belt 11 to push the lining fabric backward and can push the lining fabric to the sewing station for sewing processing, so as to realize the automated feeding of the lining fabric.

[0051] S3, the cutting blade 5 moves downward away from the cutting die 14, so that the lining belt can be conveyed between the cutting die 14 and the cutting blade 5.

[0052] S4, the driven roller 42 is driven to move and abut against the feed roller 4, so that the driven roller 42 and the feed roller 4 press against the lining belt from above and below;

[0053] S5, the push plate 2 is driven forward by the transmission belt 11 to reset, and the transmission belt 11 synchronously drives the feeding roller 4 to rotate and cooperates with the driven roller 42 to convey the lining belt so that the punching knife 5 can punch out the lining again.

[0054] S6. The driven roller 42 is driven away from the feeding roller 4 so that the lining belt on the driven roller 42 is away from the feeding roller 4, so as to avoid the feeding roller 4 driving the lining belt to convey displacement during the process of the push plate 2 pushing the lining material.

[0055] When the lining is being sewn at the sewing station, the punching blade 5 punches the lining upward through the punching die 14 so that the push plate 2 can be in the feeding state, thereby improving the efficiency of subsequent sewing processes.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
