Description

Technical Field

[0001] This utility model relates to the field of edge binding tape conveying technology, and more specifically, to a self-adhesive edge binding tape conveying device. Background Technology

[0002] The binding tape conveyor, commonly known as a "binding tape feeder" or "binding tape device," is an auxiliary device installed on industrial or specialized sewing machines. It automatically pushes binding tape and other fabric strips to the edge of the fabric and sews them together simultaneously, greatly improving the efficiency and consistency of the binding process. This device automates the binding process, significantly increasing production efficiency, ensuring uniform binding width, and reducing operational difficulty. It is an essential tool for the garment and home textile industries to perform fine edge processing.

[0003] However, existing technologies have some problems: some existing binding strips have an adhesive side, meaning they can self-adhere to the product surface. However, when these self-adhesive binding strips are conveyed by a conveyor, due to their adhesiveness, they tend to stick to the guide rollers of the conveyor, which may cause entanglement, stretching, etc., affecting the smoothness of conveying, requiring machine downtime for maintenance, and reducing production efficiency. Therefore, we propose a self-adhesive binding strip conveying device. Utility Model Content

Detailed Implementation

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] like Figures 1-9 As shown, a self-adhesive binding tape conveying device includes a control unit 1, a crossbar 2 fixedly mounted on the control unit 1, a baffle 3 fixedly connected to the crossbar 2, a guide wheel 4 and a sensing rod 5 on the control unit 1 for conveying the binding tape strip, a connecting rod 6 rotatably connected to the crossbar 2, a pressure roller 7 rotatably connected to the connecting rod 6, a frame 8 fixedly mounted on the baffle 3, a vertical rod 9 movably inserted into the frame 8, a round rod 10 fixedly connected to the bottom of the vertical rod 9, and a top plate 11 fixedly connected to the top of the vertical rod 9. The top plate 11 and the frame 8 are also connected by a drive assembly to cause the round rod 10 to move and break the adhesion between it and the binding tape strip. A pull rod 12 is movably inserted into the connecting rod 6, and the pull rod 12 is also connected to the control unit 1 and the baffle 3 by an adjustment assembly to adjust the distance between the pressure roller 7 and the guide wheel 4.

[0033] The binding tape strip passes around the round rod 10, passes between the guide wheel 4 and the pressure roller 7, and is conveyed by the rotation of the guide wheel 4. When the binding tape strip is used at the consumption end, the binding tape strip between the sensing rod 5 and the guide wheel 4 gradually tightens, which drives the sensing rod 5 to move upward. After the signal is transmitted to the guide wheel 4, it will continue to rotate and convey the binding tape strip. This is the conveying principle, which will not be elaborated further. When conveying self-adhesive binding tape strips, the operator can make the round rod 10 vibrate slightly through the drive component, so that the vibration energy is transferred to the adhesive layer of the binding tape, which will destroy the adhesion force that may be formed between it and the surface of the round rod 10, ensuring smoother conveying. In addition, the operator can adjust the distance between the pressure roller 7 and the guide wheel 4 through the adjustment component, so as to convey binding tape strips of different thicknesses under appropriate pressure, further reducing the adhesion force, thereby improving the smoothness of conveying and preventing the self-adhesive binding tape strips from sticking to the conveying device during conveying and affecting normal operation.

[0034] The self-adhesive binding tape conveying device described above includes a drive motor 13, which is fixedly mounted on a frame 8. The output shaft of the drive motor 13 is connected to a rotating shaft 14 via a coupling. An eccentric wheel 15 is fixedly connected to the other end of the rotating shaft 14, and a top plate 11 is located at the bottom of the eccentric wheel 15.

[0035] In the aforementioned self-adhesive binding tape conveying device, a spring 16 is movably sleeved on the outer surface of the vertical rod 9, and the two ends of the spring 16 are respectively fixedly connected to the round rod 10 and the frame 8.

[0036] By setting the spring 16 to a compressed state, the elastic force of the spring 16 will cause the top plate 11 to tend to move upward, thus abutting against the surface of the eccentric wheel 15. When the operator starts the drive motor 13, the rotating shaft 14 can drive the eccentric wheel 15 to rotate. With the cooperation of the spring 16, the top plate 11 can drive the round rod 10 to vibrate slightly, so that the vibration energy is transmitted to the adhesive layer of the edge tape, destroying the adhesion force that may be formed between it and the surface of the round rod 10, ensuring that the conveying is absolutely smooth.

[0037] In the aforementioned self-adhesive binding tape conveying device, a ball bearing 17 is movably mounted on the top of the top plate 11, and the ball bearing 17 is movably connected to the eccentric wheel 15.

[0038] By setting the ball bearing 17, hard friction between the eccentric wheel 15 and the top plate 11 can be avoided, making the eccentric wheel 15 rotate more smoothly and reducing wear.

[0039] The self-adhesive binding tape conveying device described above includes an adjusting component comprising two toothed plates 18, which are respectively fixedly installed on the control unit 1 and the baffle 3. One end of the pull rod 12 is fixedly connected to a block 19, and the other end of the pull rod 12 is fixedly connected to a toothed block 20. The toothed block 20 and the toothed plate 18 are meshed together.

[0040] The operator can move the two blocks 19 toward each other, which in turn drives the two toothed blocks 20 to move toward each other via the two pull rods 12. This releases the meshing between the toothed blocks 20 and the toothed plate 18, thus releasing the limit on the connecting rod 6. The operator can then rotate the connecting rod 6 to finely adjust the position of the pressure roller 7, thereby adjusting the distance between the pressure roller 7 and the guide wheel 4. This allows for the conveying of binding strips of different thicknesses under appropriate pressure, further reducing adhesion.

[0041] The aforementioned self-adhesive binding tape conveying device has a folding plate 21 fixedly installed on the connecting rod 6, a threaded rod 22 threadedly connected to the folding plate 21, a push rod 23 rotatably connected to the bottom of the threaded rod 22, a through hole 24 opened on the block 19, and a round block 25 located inside the through hole 24 fixedly connected to the push rod 23.

[0042] By rotating the threaded rod 22, the push rod 23 can drive the round block 25 to move up or down, thereby causing the surface of the round block 25 to press against the inner wall of the through hole 24, thus adjusting the position of the square block 19 to change the engagement state between the toothed block 20 and the toothed plate 18.

[0043] In the aforementioned self-adhesive binding tape conveying device, a round block 25 is slidably connected inside a through hole 24, and the inner wall of the through hole 24 is coated with a lubricating layer.

[0044] By coating the inner wall of the through hole 24 with a lubricating layer, the circular block 25 can slide more smoothly inside the through hole 24.

[0045] In the aforementioned self-adhesive binding tape conveying device, a rubber strip 26 is fixedly installed on the surface of the guide wheel 4, and a ceramic sleeve 27 is fixedly sleeved on the surface of the pressure roller 7.

[0046] When the binding strip passes between the guide roller 4 and the pressure roller 7, it is pressed onto the surface of the ceramic sleeve 27 by the rubber strip 26. The rubber strip 26 has soft and elastic properties, which can form good compression on the binding strip, thus improving the conveying. Furthermore, the ceramic sleeve 27 has low surface adhesion, which can reduce the adhesion between the adhesive layer of the binding strip and the ceramic sleeve 27, thus making the conveying smoother.

[0047] The aforementioned self-adhesive binding tape conveying device has a rotating roller 28 rotatably connected to the outer surface of the sensing rod 5, and Teflon strips are spaced apart on the surface of the rotating roller 28.

[0048] By utilizing the ultra-low surface energy of Teflon, the contact area is physically reduced, which can fundamentally reduce the adhesion between the Teflon and the binding strip.

[0049] In the aforementioned self-adhesive binding tape conveying device, a retaining ring 29 is movably sleeved on the outer surface of the crossbar 2, and a bolt 30 is threadedly connected to the retaining ring 29, with the bottom end of the bolt 30 abutting against the crossbar 2.

[0050] The staff can adjust the retaining ring 29 to the position of the crossbar 2 and then tighten the bolt 30 to limit it, so as to limit it when conveying binding strips of different widths and ensure the stability of the conveying.

[0051] Working principle and usage process of this utility model:

[0052] When the self-adhesive binding tape is conveyed on the device, the operator can start the drive motor 13, which will cause the rotating shaft 14 to drive the eccentric wheel 15 to rotate. With the cooperation of the spring 16, the top plate 11 will cause the round rod 10 to vibrate slightly, thus transferring the vibration energy to the adhesive layer of the binding tape, breaking the adhesion between it and the surface of the round rod 10, ensuring smoother conveying. If the operator needs to adjust the distance between the guide roller 4 and the pressure roller 7 to better convey binding tape of different thicknesses, the operator can rotate the threaded rod 22, which will cause the push rod 23 to drive the round block 25 upwards, thus allowing the round block 25 to... The inner wall of the surface extrusion hole 24 is pressed, thereby adjusting the position of the block 19 to change the engagement state between the toothed block 20 and the toothed plate 18. When the block 19 drives the two toothed blocks 20 to move towards each other through the two pull rods 12, the meshing state between the toothed block 20 and the toothed plate 18 can be released, thus releasing the limit on the connecting rod 6. This allows the connecting rod 6 to be rotated to finely adjust the position of the pressure roller 7, thereby adjusting the distance between the pressure roller 7 and the guide wheel 4. This allows for the conveying of edge binding strips of different thicknesses under appropriate pressure, further reducing adhesion and improving conveying smoothness. This also prevents the self-adhesive edge binding strips from adhering to the conveying device during conveying, thus affecting normal operation.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
