Description

Technical Field

[0001] This utility model belongs to the field of sewing machine technology, specifically relating to a fabric guide device for a fully automatic hem sewing machine. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a fabric, allowing one or more layers of fabric to interweave or sew together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing machines are fast and easy to use. The fabric guide device of a fully automatic hem sewing machine is required to guide the fabric during use.

[0003] The prior art patent publication number CN216193232U describes a fabric guide device for a fully automatic hem sewing machine. This patent includes a base plate with a groove. A slide rod is slidably connected inside the groove. A rotating rod is threadedly connected inside the slide rod. A fixed plate is rotatably sleeved on the outer side of the rotating rod, and the fixed plate is fixedly connected to the base plate. A rotating ring is fixedly connected to the rotating rod and contacts the fixed plate. A support plate is fixedly connected to the slide rod and contacts the base plate. A through groove is provided on the support plate, and the inside of the through groove is movably connected to… With connecting blocks, this device, through the design of guide rollers, can guide the fabric and adjust the height of the guide rollers, thereby adjusting the fabric tension and improving the performance. However, in actual use, there are still the following shortcomings: In practice, the fabric is prone to dust, fiber debris and other impurities during the conveying process. The device lacks a dust removal function, and impurities will remain on the fabric surface or in the gaps of the equipment as the guide rollers and other components are driven, affecting the subsequent sewing quality. At the same time, the fabric is prone to static electricity during the friction of the guide rollers, which can cause the fabric edges to curl and stick together, affecting the smooth conveying of the fabric.

[0004] Therefore, a fabric guiding device for a fully automatic hem sewing machine is needed to solve the problems in the existing technology where dust easily adheres to the fabric and static electricity is generated during the conveying process, affecting the subsequent sewing quality. Utility Model Content

[0005] The purpose of this invention is to provide a fabric guide device for a fully automatic hem sewing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric guiding device for a fully automatic hem sewing machine, comprising a frame, a dust removal mechanism on one side of the frame, a fabric inlet corresponding to the dust removal mechanism fixedly connected to one side of the frame, a first fabric guiding roller rotatably connected to the other side of the frame near the top, two support frames fixedly connected to the other side of the frame near the bottom, a second fabric guiding roller rotatably connected between the two support frames, and an antistatic mechanism provided between the first and second fabric guiding rollers.

[0007] It should be noted in the solution that the dust removal mechanism includes a U-shaped frame fixedly connected to one side of the frame. Two bases are fixedly connected to the lower top surface and the upper bottom surface of the U-shaped frame. A round rod is slidably connected to the inner end of each of the bases. A spring is sleeved on the outer wall of each of the round rods. A convex frame is fixedly connected to the inner end of each pair of corresponding round rods. A rotating shaft is rotatably connected between the inner walls of the front and rear ends of the two convex frames. A cleaning roller is fixedly connected to the outer wall of each of the two rotating shafts.

[0008] It is worth noting that all of the springs are fixedly connected between the base and the convex frame.

[0009] Furthermore, it should be noted that both cleaning rollers have multiple evenly distributed bristles fixedly connected to their outer walls.

[0010] In a preferred embodiment, the static elimination mechanism includes two connecting plates fixedly connected to the outside of the support frame. Each connecting plate has a support column fixedly connected to its top. A horizontal plate is fixedly connected between the two support columns. A threaded rod is rotatably connected inside the horizontal plate. A rotating plate is fixedly connected to the front end of the threaded rod. A concave frame is rotatably connected to the rear end of the threaded rod. Two guide posts are fixedly connected to the front end of the concave frame. A T-shaped plate is detachably connected to the rear end of the concave frame. Two fixing bolts corresponding to the T-shaped plate are rotatably connected to the top of the concave frame. Multiple evenly distributed conductive bristles are fixedly connected to the rear end of the T-shaped plate.

[0011] In a preferred embodiment, a threaded sleeve corresponding to the threaded rod is fixedly connected inside the horizontal plate, and the threaded rod is rotatably connected to the inner wall of the threaded sleeve. A through hole corresponding to the guide post is opened inside the horizontal plate.

[0012] In a preferred embodiment, the outer wall of the T-shaped plate is tightly fitted to the inner wall of the concave frame, and the top of the T-shaped plate is provided with a mounting groove corresponding to the fixing bolt.

[0013] Compared with the prior art, the fabric guide device of the fully automatic hem sewing machine provided by this utility model has at least the following beneficial effects: (1) By setting up a dust removal mechanism, the cleaning roller in the loop frame can closely fit the fabric surface by means of the spring pushing the convex frame. When the fabric enters from the inlet, the bristles on the outer wall of the cleaning roller can effectively remove dust and fiber debris from the fabric, preventing impurities from being rolled into the sewing area with the fabric, preventing uneven stitches, broken threads and other problems, improving the quality of subsequent sewing, and reducing the wear of equipment parts caused by the accumulation of impurities.

[0014] (2) By setting an anti-static mechanism, the position of the concave frame can be adjusted by rotating the rotating plate through the threaded rod, so that the conductive bristles on the T-plate contact the fabric and discharge the static electricity generated by the friction of the fabric, avoiding the fabric from curling or sticking due to static electricity, ensuring that the fabric is smoothly conveyed between the first guide roller and the second guide roller, preventing sewing size deviation caused by fabric offset, and improving the accuracy of the guide.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Please see Figure 1-4 This utility model provides a fabric guiding device for a fully automatic hem sewing machine, including a frame 1. A dust removal mechanism 2 is provided on one side of the frame 1. A fabric inlet 3 corresponding to the dust removal mechanism 2 is fixedly connected to one side of the frame 1. A first fabric guiding roller 4 is rotatably connected to the other side of the frame 1 near the top. Two support frames 5 are fixedly connected to the other side of the frame 1 near the bottom. A second fabric guiding roller 6 is rotatably connected between the two support frames 5. An antistatic mechanism 7 is provided between the first fabric guiding roller 4 and the second fabric guiding roller 6.

[0019] Further as Figure 3As shown, it is worth noting that the dust removal mechanism 2 includes a U-shaped frame 201 fixedly connected to one side of the frame 1. Two bases 202 are fixedly connected to the lower top surface and the upper bottom surface of the U-shaped frame 201. Round rods 203 are slidably connected to the inner ends of multiple bases 202. Springs 204 are sleeved on the outer walls of multiple round rods 203. A convex frame 205 is fixedly connected to the inner ends of every two corresponding round rods 203. A rotating shaft 206 is rotatably connected between the front and rear end inner walls of the two convex frames 205. Cleaning rollers 207 are fixedly connected to the outer wall of shaft 206. By setting up dust removal mechanism 2, the cleaning rollers 207 in the loop frame 201 can closely fit the fabric surface by the elastic force of spring 204 pushing convex frame 205. When the fabric enters from the inlet 3, the bristles on the outer wall of the cleaning rollers 207 can effectively remove dust and fiber debris from the fabric, prevent impurities from being rolled into the sewing area with the fabric, prevent uneven stitches, broken threads and other problems, improve the quality of subsequent sewing, and reduce the wear of equipment parts caused by the accumulation of impurities.

[0020] Further as Figure 3 As shown, it is worth noting that multiple springs 204 are fixedly connected between the base 202 and the convex frame 205, ensuring that the springs 204 can drive the convex frame 205 to slide flexibly, so that the two cleaning rollers 207 can adapt to fabrics of different thicknesses.

[0021] Further as Figure 3 As shown, it is worth noting that both cleaning rollers 207 have multiple evenly distributed bristles fixedly connected to their outer walls. The even distribution of the bristles ensures that the cleaning rollers 207 fully contact the fabric surface during operation, removing dust and fiber debris and improving product quality.

[0022] As can be seen from the above working process: by setting up the dust removal mechanism 2, the cleaning roller 207 in the loop frame 201 can closely fit the fabric surface by the elastic force of the spring 204 pushing the convex frame 205. When the fabric enters from the inlet 3, the bristles on the outer wall of the cleaning roller 207 can effectively remove dust and fiber debris from the fabric, prevent impurities from being rolled into the sewing area with the fabric, prevent uneven stitches, broken threads and other problems, improve the quality of subsequent sewing, and at the same time reduce the wear of equipment parts caused by the accumulation of impurities.

[0023] Further as Figure 4As shown, it is worth noting that the static elimination mechanism 7 includes two connecting plates 701 fixedly connected to the outside of the support frame 5. Each connecting plate 701 has a support column 702 fixedly connected to its top. A horizontal plate 703 is fixedly connected between the two support columns 702. A threaded rod 704 is rotatably connected inside the horizontal plate 703. A rotating plate 705 is fixedly connected to the front end of the threaded rod 704. A concave frame 706 is rotatably connected to the rear end of the threaded rod 704. Two guide posts 707 are fixedly connected to the front end of the concave frame 706. A T-shaped plate 708 is detachably connected to the rear end of the concave frame 706. The top of the 6th section has two fixing bolts 709 corresponding to the T-shaped plate 708. The rear end of the T-shaped plate 708 is fixedly connected with multiple evenly distributed conductive bristles 710. By setting an anti-static mechanism 7, rotating the rotating plate 705 can adjust the position of the concave frame 706 through the threaded rod 704, so that the conductive bristles 710 on the T-shaped plate 708 come into contact with the fabric, dissipating the static electricity generated by the friction of the fabric. This prevents the fabric from curling or sticking due to static electricity, ensuring smooth fabric conveying between the first guide roller 4 and the second guide roller 6, preventing sewing size deviation caused by fabric offset, and improving the accuracy of the guide roller.

[0024] Further as Figure 4 As shown, it is worth noting that a threaded sleeve corresponding to the threaded rod 704 is fixedly connected inside the horizontal plate 703, and the threaded rod 704 is rotatably connected to the inner wall of the threaded sleeve. The cooperation between the threaded rod 704 and the threaded sleeve provides a precise linear adjustment function. When the threaded rod 704 rotates, the threaded sleeve guides the threaded rod 704 to move precisely along the axial direction, providing driving force for the movement of the concave frame 706. A through hole corresponding to the guide post 707 is opened inside the horizontal plate 703. The through hole cooperates with the guide post 707 to limit and guide the movement of the concave frame 706, making its movement more stable.

[0025] Further as Figure 4 As shown, it is worth noting that the outer wall of the T-shaped plate 708 and the inner wall of the concave frame 706 are tightly fitted together. This tight fit can effectively prevent loosening or displacement caused by vibration or load during equipment operation, thereby improving the stability of the equipment. In addition, the top of the T-shaped plate 708 has a mounting groove corresponding to the fixing bolt 709. The mounting groove facilitates quick disassembly and installation using the fixing bolt 709, making it convenient for inspection, replacement or adjustment, and reducing maintenance time and costs.

[0026] This solution has the following working process: In actual use, the fabric enters from the inlet 3 on one side of the frame 1, corresponding to the dust removal mechanism 2. It first contacts the cleaning roller 207 inside the dust removal mechanism 2. In the dust removal mechanism 2, the round rod 203, which is slidably connected to the base 202 on the lower top surface and upper bottom surface of the U-shaped frame 201, has a spring 204 sleeved on its outer wall. Under the elastic force between the base 202 and the convex frame 205, the spring pushes the convex frame 205 towards the fabric, causing the cleaning roller 207 on the outer wall of the pivot 206 between the inner walls of the front and rear ends of the convex frame 205 to tightly adhere to the fabric surface. During the fabric conveying process, the cleaning roller 207 rotates, and the evenly distributed bristles on its outer wall remove dust and fiber debris from the fabric surface, completing the fabric dust removal. The cleaned fabric continues to be conveyed to the other side of the frame 1. First, bypass the first guide roller 4, which is rotatably connected near the top, and then go down past the second guide roller 6, which is rotatably connected between the two support frames 5 near the bottom on the other side of the frame 1. The cooperation between the first guide roller 4 and the second guide roller 6 achieves the guiding and conveying of the fabric. Rotate the rotating plate 705 at the front end of the threaded rod 704 in the antistatic mechanism 7. Since the threaded rod 704 is rotatably connected to the threaded sleeve inside the horizontal plate 703, and the horizontal plate 703 is fixed to the outside of the support frame 5 by the support column 702 and the connecting plate 701, the rotation of the threaded rod 704 drives the concave frame 706 at the rear end to move. The guide post 707 at the front end of the concave frame 706 slides along the through hole inside the horizontal plate 703 to ensure smooth movement. Adjust the position of the concave frame 706 so that the rear end of the concave frame 706 is detachably connected to the T-shaped frame 706 by the fixing bolt 709. The template 708 fits tightly against the inner wall of the concave frame 706. The conductive bristles 710 at the rear end contact the fabric surface and discharge the static electricity generated by friction during the guiding and conveying process, thus completing the static elimination treatment. After the dust removal, guiding, and static elimination treatment, the fabric is continuously conveyed to the sewing mechanism of the fully automatic hem sewing machine, providing clean, flat, and static-free fabric for subsequent precise sewing, ensuring the stable operation of the sewing work.

[0027] In summary: By setting up the dust removal mechanism 2, the cleaning roller 207 inside the U-shaped frame 201, with the help of the spring 204 pushing the elastic force of the convex frame 205, can closely fit the fabric surface. When the fabric enters from the inlet 3, the bristles on the outer wall of the cleaning roller 207 can effectively remove dust and fiber debris from the fabric, preventing impurities from being rolled into the sewing area with the fabric, preventing uneven stitches, broken threads, and other problems, improving the quality of subsequent sewing, and reducing the wear of equipment parts caused by the accumulation of impurities. By setting up the anti-static mechanism 7, rotating the rotating plate 705 can adjust the position of the concave frame 706 through the threaded rod 704, so that the conductive bristles 710 on the T-shaped plate 708 contact the fabric, discharging the static electricity generated by the friction of the fabric, preventing the fabric from curling or sticking due to static electricity, ensuring smooth fabric conveying between the first guide roller 4 and the second guide roller 6, preventing sewing size deviation caused by fabric offset, and improving the accuracy of the guide.

[0028] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
