Description
Technical Field
[0001] This application relates to the field of fabric tape edging, and more particularly to a pull-tube feeding device. Background Technology
[0002] In textile or garment production, a "roller" is an auxiliary tool used to roll fabric strips into a tube shape for easier sewing or cutting. It is commonly used to make parts that require hemming, such as cuffs and trouser legs.
[0003] A sewing tube typically consists of a hemming channel, a base, and an adjustment mechanism. To use it, first, thread screws through the base to secure the tube to the sewing machine or workbench, ensuring it is firmly fixed. Then, insert one end of the fabric strip into the tube's inlet and slowly pull the strip through the hemming channel to form a tube shape. Next, place the edge of the rolled fabric strip under the sewing machine needle, start the sewing machine, and sew along the rolled edge, ensuring the stitches are even and strong. Finally, the width or angle of the hemming channel can be adjusted using the adjustment mechanism to accommodate fabric strips of different thicknesses or widths.
[0004] In the existing technology, when the edge curling type of the fabric belt changes during the use of the pull-tube feeding device, it is usually necessary to replace it with a suitable pull tube. However, the disassembly and assembly process is complicated. Either the entire pull tube needs to be replaced, or the fasteners that fix the edge curling channel need to be removed and the edge curling channel needs to be replaced separately. Both of these require the assistance of tools, which not only increases the complexity of the operation, but also consumes time and effort, thereby affecting the edge curling efficiency of the fabric belt and reducing the practicality of the pull-tube feeding device. Utility Model Content
[0005] In order to reduce the number of steps required to change the feed tube and improve the efficiency of feed tube replacement and the efficiency of fabric tape edge rolling, this application provides a feed tube feeding device.
[0006] The present application provides a pull-tube feeding device with the following technical solution:
[0007] A feeder device includes a base, a connecting plate mounted on the base, an adjusting member mounted on the upper side of the connecting plate, and a rolled edge channel mounted on one side of the connecting plate. Two trapezoidal blocks are fixedly connected to one side of the rolled edge channel.

[0012] By adopting the above technical solution, the reset spring can provide continuous elastic force to the toothed block, ensuring that the toothed block and the toothed groove always maintain a tight engagement; the design of the positioning rod can prevent the toothed block from shifting or getting stuck during the sliding process; and the reset spring allows the toothed block to automatically return to the initial position after unlocking, without the need for manual operation, which can improve the convenience and efficiency of operation.
[0013] Optionally, each of the toothed blocks has a limiting block fixedly connected to both its upper and lower ends, and the limiting block is slidably connected to the inner wall of the groove.
[0014] By adopting the above technical solution, the movement range of the toothed block can be limited and the guiding effect can be enhanced, thereby improving the accuracy of locking and unlocking the toothed block and preventing the toothed block from detaching from the groove or becoming misaligned during movement, thus improving the stability and service life of the structure.
[0015] Optionally, one end of the hemming channel is fixedly connected to a leveling component for guiding the fabric tape.
[0016] By adopting the above technical solution, the fabric tape can be effectively guided into the edge-rolling channel, ensuring that the fabric tape remains flat during the edge-rolling process.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0033] This application discloses a pull tube feeding device.
[0034] Reference Figure 1 The feed tube device includes a base 1, a connecting plate 2 rotatably mounted on the base 1, an adjusting component 3 rotatably mounted on the upper side of the connecting plate 2, and a hemming channel 4 fixedly mounted on one side of the connecting plate 2. The base 1 has multiple rectangular openings 11 for needles to pass through, and two through holes for screws or bolts to pass through, which are used to fix the base 1 to the sewing machine. By adjusting the adjusting component 3, the connecting plate 2 can be rotated on the upper side of the base 1, thereby adjusting the angle of the hemming channel 4. The hemming channel 4 allows the fabric tape to pass through. A leveling component 41, a continuous and uniformly curved stainless steel strip, is fixedly connected to the inlet of the hemming channel 4. The leveling component 41 guides the fabric tape smoothly into the inlet of the hemming channel 4. A guide groove 42 is provided on one side of the hemming channel 4 to guide the movement of the fabric tape.
[0035] In use, first, pass the fabric strip through the flattening piece 41 and insert one end of the fabric strip into the entrance of the hemming channel 4; then, use a tool to insert into the guide groove 42 to contact the fabric strip, and then push the fabric strip along the guide groove 42 to move it in the hemming channel 4 until one end of the fabric strip extends out of the exit of the hemming channel 4; then, use a sewing machine to sew the hemmed fabric strip.
[0036] refer to Figure 1 , Figure 2The adjusting component 3 includes a rotating handle 31 and a fastener 32 threadedly connected to one end of the rotating handle 31. The connecting plate 2 has a positioning hole 23 for the fastener 32 to pass through, which improves the stability of the connection between the adjusting component 3 and the connecting plate 2. The lower end of the fastener 32 is threadedly connected to the inner wall of the base 1 to prevent the connecting plate 2 from falling off or becoming misaligned. The rotating handle 31 is rotatably connected to the upper side of the connecting plate 2 via the fastener 32.
[0037] In use, the connecting plate 2 can be unlocked by turning the handle 31 and rotating the connecting plate 2 to the corresponding position; then, the connecting plate 2 can be locked by turning the handle 31 in the opposite direction, thereby completing the angle adjustment of the crimping channel 4.
[0038] refer to Figure 3 , Figure 4 Two trapezoidal blocks 5 are fixedly connected to the side of the rolled edge channel 4 opposite to the guide groove 42. Two slots 21 for inserting the trapezoidal blocks 5 are provided on one side of the connecting plate 2. When the trapezoidal blocks 5 are in contact with the inner wall of the slots 21, the rolled edge channel 4 is fixed to one side of the connecting plate 2. A sliding groove 22 communicating with the two slots 21 is provided on the inner wall of the connecting plate 2. Two locking elements 6 for locking the two trapezoidal blocks 5 are slidably connected to the inner wall of the sliding groove 22. The two locking elements 6 can simultaneously lock both sides of the two trapezoidal blocks 5. After inserting the trapezoidal blocks 5 into the slots 21, the two locking elements 6 automatically lock the trapezoidal blocks 5, completing the installation of the rolled edge channel 4.
[0039] refer to Figure 4 , Figure 5 Each locking component 6 consists of a sliding plate 61 and two toothed blocks 62 fixedly connected to one side of the sliding plate 61, with the toothed patterns of the two toothed blocks 62 facing the same direction. A push plate 7 is fixedly connected to one end of the sliding plate 61, and one end of the push plate 7 is slidably connected to the inner wall of the slide groove 22. The other end of the sliding plate 61 is located on one side of the adjusting component 3. Pushing the push plate 7 can cause the sliding plate 61 and the toothed blocks 62 to slide along the inner wall of the slide groove 22. Toothed grooves 51 for the toothed blocks 62 to be inserted are provided on both sides of the lower end of the trapezoidal block 5 to ensure the stability of the connection between the trapezoidal block 5 and the inner wall of the slot 21. A return spring 63 is fixedly connected between one side of each toothed block 62 and the inner wall of the slide groove 22. The return spring 63 is used to push the toothed block 62 to automatically return, improving the stability of the engagement between the toothed block 62 and the toothed groove 51.
[0040] In use, first, insert the trapezoidal block 5 into the slot 21. The lower end of the trapezoidal block 5 will push the toothed blocks 62 on both sides to retract into the inner wall of the slide groove 22 until the lower side of the trapezoidal block 5 is completely in contact with the bottom wall of the slot 21. Then, the return spring 63 pushes the toothed block 62 to move, so that one side of it is inserted into the toothed groove 51, thus fixing the trapezoidal block 5. When it is necessary to remove the rolled edge channel 4, push the two push plates 7 at the same time, causing the slide plate 61 and the two toothed blocks 62 to slide on the inner wall of the slide groove 22 until the toothed blocks 62 are disengaged from the toothed groove 51. At this time, support the lower side of the rolled edge channel 4 and move it upward, causing the trapezoidal block 5 to disengage from the slot 21, thus completing the removal of the rolled edge channel 4.

Limiting blocks 621 are fixedly connected to both the upper and lower ends of the toothed block 62. The limiting blocks 621 are slidably connected to the inner walls of both sides of the slide groove 22 to limit the movement range of the toothed block 62 and prevent the toothed block 62 from dislodging from the slide groove 22. The positioning rod 64 and the limiting blocks 621 ensure the stability of the movement of the toothed block 62.
[0042] The implementation principle of the feeder device in this embodiment is as follows: In use, firstly, the connecting plate 2 is installed on the upper side of the base plate by adjusting the adjusting member 3, and then the base 1 is fixed on the installation position of the sewing machine; then, the hemming channel 4 is moved to insert the two trapezoidal blocks 5 into the slot 21, and the toothed block 62 is pushed to slide in the slide groove 22 by the return spring 63 until the toothed block 62 is inserted into the toothed groove 51, thus completing the installation of the hemming channel 4; next, the fabric tape is passed through the leveling member 41, and then one end of the fabric tape is inserted into the entrance of the hemming channel 4; then, a tool is used to pass through the guide groove 42 to contact the fabric tape and push the fabric tape to move in the hemming channel 4 until one end of the fabric tape extends out of the exit of the hemming channel 4, thus completing the hemming of the fabric tape. When it is necessary to replace the rolled edge channel 4, push the two push plates 7 at the same time, which will cause the slide plate 61 and the two toothed blocks 62 to slide on the inner wall of the slide groove 22 until the toothed blocks 62 are disengaged from the toothed groove 51. At this time, move the rolled edge channel 4 upward to pull it, causing the trapezoidal block 5 to disengage from the slot 21, thus completing the removal of the rolled edge channel 4.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
