Fabric conveying device

Abstract

This invention relates to the field of textile processing machinery and equipment technology, specifically a fabric conveying device, including a packaging conveyor frame, a drive motor fixed to one side of the packaging conveyor frame, and several conveying rollers that are equidistantly and rotatably installed inside the packaging conveyor frame. A transmission belt drives a positioning seat to move synchronously with the conveyor belt. Simultaneously, a packaging pre-positioning component achieves elastic pressing through the cooperation of a sliding plate and a contact plate. When the contact roller contacts the contact plate, the sliding plate drives the positioning block closer to the edge of the fabric. The repulsive force between the electromagnet and the magnetic block forms an elastic thrust, which, combined with the buffering effect of a compression spring, allows the positioning block to contact the fabric in a flexible pressing manner. This flexible pressing can form a stable pre-positioning for packaging of medium-thick fabrics such as cotton and chemical fibers, preventing edge friction and fuzzing that would cause exposed rough edges during packaging, ensuring the neatness of the packaging appearance. At the same time, while counteracting lateral offset forces, it does not hinder the conveying power, ensuring accurate delivery of the fabric to the packaging station.

Description

Technical Field

[0001] This invention relates to the field of textile processing machinery and equipment technology, specifically to a fabric conveying device. Background Technology

[0002] Flocking is a process in which short fibers are vertically fixed onto a substrate coated with an adhesive. The principle of flocking utilizes the physical property of like charges repelling and unlike charges attracting. The fabric is given a negative charge, and when the object to be flocked is placed at zero potential or grounded, the fabric, attracted by the opposite potential, is accelerated vertically and rises onto the surface of the object. In the fabric production process, the flocked fabric needs to be conveyed to the packaging stage. A conveyor system is used to smoothly transport the fabric to the packaging station to meet the requirements of folding packaging, roll film sealing, and other packaging processes. Fabrics are classified by material, including viscose flocking, nylon flocking, acrylic flocking, and cotton flocking. Before packaging, the fabric needs to be conveyed and packaged according to specifications. The stability of this conveying process directly affects the subsequent packaging quality.

[0003] To prevent fabric deviation, existing conveyor and sorting devices before fabric packaging commonly use two basic limiting methods: The first method requires workers to constantly monitor the position of the fabric edge and frequently adjust the tilt angle of the side guide rollers with tools. The friction of the guide rollers on the fabric guides it back to the correct path. However, if the adjustment is not timely, the fabric edge may become misaligned when it enters the packaging station. The second method involves installing metal or plastic baffles on both sides of the conveyor belt to abut against the fabric edge with a certain gap, thus restricting its lateral movement. However, the actual effectiveness of these two methods is limited, especially the baffle limiting method, which has a more significant impact on packaging quality.

[0004] Existing fabric conveying and packaging devices, when using baffles for limiting movement, are prone to batch damage due to continuous contact between the fabric edges and the baffles. For medium-thick fabrics such as cotton and synthetic fibers, the edges are continuously rubbed together, creating burrs that are exposed during the packaging process, severely affecting the flatness of the packaging appearance and requiring subsequent trimming to meet packaging quality inspection standards. Simultaneously, for extremely lightweight fabrics like chiffon and lace, the friction between them and the conveyor belt is very low. The resistance from the baffles can easily counteract the conveyor belt's driving force, causing the fabric to slip and even pile up. Once piled up, it not only blocks subsequent conveying and interrupts the packaging process, but the piled fabric may also be squeezed by subsequent fabrics, creating deep creases. These creases are permanently retained after packaging, reducing the flatness of the finished product. Workers need to frequently stop the machine to deal with the pile-up problem, severely impacting the rhythm and efficiency of the packaging production line. Summary of the Invention

[0005] The purpose of this invention is to provide a fabric conveying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fabric conveying device, comprising a packaging conveyor frame, a drive motor fixed to one side of the packaging conveyor frame, and a plurality of conveying rollers rotatably installed inside the packaging conveyor frame at equal intervals. Two transmission belts are symmetrically sleeved on the outer sides of both sides of the plurality of conveying rollers, and a conveyor belt is connected and fixed between the two transmission belts. A plurality of positioning seats are equidistantly fixedly installed around the top side of one side of each of the two transmission belts. Each positioning seat has a packaging pre-positioning component and an indentation processing component on its top side. The packaging pre-positioning component includes a sliding plate, two limiting cylinders, and a mounting block. The sliding plate is laterally slidably engaged with the top side of the positioning seat. The two limiting cylinders are symmetrically and longitudinally fixedly installed on the top sides of the sliding plate. The mounting block is located on the bottom side of the sliding plate. The indentation processing component includes a pressure roller and a liquid storage tank. The pressure roller is located on the bottom side of the sliding plate near the conveyor belt, and the liquid storage tank is fixedly installed on the top side of the sliding plate near the pressure roller.

[0007] Furthermore, one end of one of the conveying rollers is coaxially fixed to the output end of the drive motor, and both sides of the top of the packaging conveyor are fixedly mounted with abutment plates by brackets, and both ends of the abutment plates are set in an arc shape.

[0008] Furthermore, two limiting strips are symmetrically fixedly installed on the outer sides of the sliding plate. One side of each limiting strip is slidably engaged and installed inside one side of the positioning seat. An abutting roller is rotatably installed on the outer side of the sliding plate near the abutting plate. A tension spring is fixedly installed on the outer side of the sliding plate away from the abutting roller. A fixing block is fixedly installed on the outer side of the limiting strip near the tension spring. The end of the tension spring away from the sliding plate is fixedly installed on the outer side of the fixing block.

[0009] Furthermore, a first conductive block is fixedly installed on the side of the sliding plate near the contact roller, a second conductive block is fixedly installed on the side of the positioning seat near the first conductive block, an electromagnet is fixedly installed at the top of each of the two limiting cylinders, the second conductive block and the electromagnet are connected by a wire, and a magnet is slidably engaged inside the top of each of the two limiting cylinders, the adjacent surfaces of the magnet and the electromagnet are set with the same pole.

[0010] Furthermore, a limiting post is fixedly installed at the bottom end of the magnet block, and the bottom end of the limiting post is fixedly installed through and on the outside of the top side of the mounting block. A positioning block is fixedly installed at the bottom end of the mounting block. The width of the pressure roller is greater than the width of the positioning block. A compression spring is sleeved on the outside of the limiting post, and the two ends of the compression spring are respectively fixedly installed on one side of the magnet block and the sliding plate.

[0011] Furthermore, two rotating seats are symmetrically fixedly installed on the outer side of the mounting block near the pressure roller. A rotating frame is rotatably installed on one side of each of the two rotating seats, and the other end of each rotating frame is rotatably installed on the outer side of the pressure roller. A thin sponge ring is fixedly sleeved through the outer side of the pressure roller.

[0012] Furthermore, each of the sliding plates is fixedly mounted with a mounting bracket on one side near the middle of the rotating frame, and a rotating shaft is fixedly mounted on the outside of one side of each mounting bracket. Each of the rotating frames is rotatably mounted on the outside of the corresponding rotating shaft at the middle of one side.

[0013] Furthermore, an auxiliary frame is fixedly installed on the outside of the liquid storage tank near the bottom end of the pressure roller. A liquid collection cylinder is fixedly installed through the inside of the auxiliary frame. A one-way liquid inlet valve pipe and a one-way liquid outlet valve pipe are fixedly installed through the top of the liquid collection cylinder. The input end of the one-way liquid inlet valve pipe is fixedly installed through the bottom end of the liquid storage tank.

[0014] Furthermore, a piston rod is slidably and sealed inside the bottom end of the liquid collecting cylinder, a spherical block is fixedly installed at the bottom end of the piston rod, a return spring is sleeved on one side of the piston rod, and the two ends of the return spring are respectively fixedly installed on the outside of one side of the spherical block and the liquid collecting cylinder. A guide pipe is horizontally fixedly installed on the outside of the side of the auxiliary frame near the bottom end of the pressure roller.

[0015] Furthermore, the output end of the one-way drain valve pipe is fixedly installed inside one side of the guide pipe, and several nozzles are fixedly installed at equal intervals inside the bottom end of the guide pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When conveying fabrics, the conveying device can break away from the rigid contact mode of traditional baffles. The positioning seat moves synchronously with the conveyor belt via the transmission belt. At the same time, the packaging pre-positioning component achieves elastic pressing through the cooperation of the sliding plate and the contact plate. When the contact roller contacts the contact plate, the sliding plate drives the positioning block to move closer to the edge of the fabric. The repulsive force of the same pole of the electromagnet and the magnetic block forms an elastic thrust. Combined with the buffering effect of the compression spring, the positioning block contacts the fabric in a flexible pressing manner. This flexible pressing can form a stable packaging pre-positioning for medium and thick fabrics such as cotton and chemical fibers, avoiding edge friction and fuzzing that would cause exposed burrs during packaging, ensuring the neatness of the packaging appearance. It can also provide appropriate pressure for light fabrics such as chiffon and lace, which can counteract lateral offset forces without hindering the conveying power, ensuring that the fabric is accurately delivered to the packaging station. This solves the problems of edge damage caused by traditional baffles affecting packaging quality inspection and slippage and accumulation of light fabrics interrupting the packaging production line, achieving stable conveying that meets the requirements of the packaging process.

[0018] 2. The pre-positioning and indentation treatment components ensure that when the positioning block descends and presses against the fabric, the rotating frame drives the pressure roller to rotate synchronously and lift it away from the fabric surface. This prevents the pressure roller from continuously contacting the fabric and causing secondary indentations before packaging. When the positioning block rises and detaches from the fabric, the rotating frame reverses and drives the pressure roller to rotate and fall against the fabric. The sliding plate resets and moves, driving the pressure roller to roll and press, forming directional roller pressing to remove indentations. This provides a smooth substrate for subsequent packaging processes. At the same time, the liquid storage tank, through the liquid collection cylinder and guide pipe, allows for the metered delivery of packaging softener to the thin sponge ring when the pressure roller rises. This achieves automatic metered liquid replenishment during lifting, ensuring sufficient liquid while preventing leakage. When the pressure roller, carrying the liquid-soaked thin sponge ring, rolls, the liquid softens the fibers, and the mechanical force forms a double repair. This significantly reduces indentations before packaging for high-end fabrics such as silk, and the precise dosage only acts on the indentation area, avoiding the large-area residue of traditional water spraying that affects the packaging adhesion effect. This directly ensures the flatness of the finished packaging and improves the packaging quality inspection pass rate. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 9 A fabric conveying device includes a packaging conveyor frame 1, a drive motor 2 fixed to one side of the packaging conveyor frame 1, and a plurality of conveying rollers 3 rotatably installed inside the packaging conveyor frame 1 at equal intervals. Two transmission belts 4 are symmetrically sleeved on the outer sides of the two sides of the plurality of conveying rollers 3. A conveyor belt 5 is connected and fixed between the two transmission belts 4. A plurality of positioning seats 7 are evenly spaced and fixedly installed around the top side of the two transmission belts 4. Each positioning seat 7 has a packaging pre-positioning component and an indentation processing component on the top side. The packaging pre-positioning component includes a sliding plate 8, two limiting cylinders 14 and a mounting block 19. The sliding plate 8 is laterally slidably engaged and installed on the outer side of the top side of the positioning seat 7. The two limiting cylinders 14 are symmetrically and longitudinally fixed on the outer sides of the top of the sliding plate 8. The mounting block 19 is located on the bottom side of the sliding plate 8.

[0035] One end of one of the conveying rollers 3 is coaxially fixed to the output end of the drive motor 2. The top two sides of the packaging conveyor frame 1 are fixedly installed with abutment plates 6 by brackets. The two ends of the abutment plates 6 are both set in an arc shape.

[0036] Two limiting strips 9 are symmetrically fixedly installed on the outer sides of the sliding plate 8. One side of each limiting strip 9 is slidably engaged and installed inside the positioning seat 7. An abutting roller 10 is rotatably installed on the outer side of the sliding plate 8 near the abutting plate 6. A tension spring 37 is fixedly installed on the outer side of the sliding plate 8 away from the abutting roller 10. A fixing block 36 is fixedly installed on the outer side of the limiting strip 9 near the tension spring 37. The end of the tension spring 37 away from the sliding plate 8 is fixedly installed on the outer side of the fixing block 36.

[0037] A first conductive block 12 is fixedly installed on the side of the sliding plate 8 near the contact roller 10. A second conductive block 13 is fixedly installed on the side of the positioning seat 7 near the first conductive block 12. Electromagnets 15 are fixedly installed on the top of each of the two limiting cylinders 14. The second conductive block 13 and the electromagnet 15 are connected by a wire. A magnet 17 is slidably engaged inside the top of each of the two limiting cylinders 14. The adjacent surfaces of the magnet 17 and the electromagnet 15 are set with the same pole.

[0038] A limiting post 16 is fixedly installed at the bottom end of the magnet block 17. The bottom end of the limiting post 16 is fixedly installed through the top side of the mounting block 19. A positioning block 20 is fixedly installed at the bottom end of the mounting block 19. The width of the pressure roller 11 is greater than the width of the positioning block 20. A compression spring 18 is sleeved on the outside of the limiting post 16. The two ends of the compression spring 18 are fixedly installed on one side of the magnet block 17 and the sliding plate 8, respectively.

[0039] In this embodiment, when the fabric conveying device is in use, it is first started by the drive motor 2. The output end of the drive motor 2 rotates, driving the conveyor roller 3, which is fixed coaxially with it, to rotate. The conveyor roller 3 drives the other conveyor rollers 3 to rotate synchronously through the transmission belts 4 on both sides, thereby causing the conveyor belt 5 between the two transmission belts 4 to operate and realize fabric conveying. At the same time, the transmission belt 4 drives the positioning seat 7 at the top to move synchronously with the conveyor belt 5. When the positioning seat 7 moves to one side of the contact plate 6, the contact roller 10 on one side of the sliding plate 8 contacts the contact plate 6, and the arc-shaped end of the contact plate 6... The end guide roller 10 pushes the sliding plate 8 to slide laterally along the positioning seat 7 (while the limiting strip 9 slides within the positioning seat 7 to ensure directional stability). At this time, the sliding plate 8 stretches the tension spring 37 on one side (the other end of the tension spring 37 is fixed to the fixing block 36 of the limiting strip 9, forming a reset force). During the movement of the sliding plate 8, the first conductive block 12 on one side contacts the second conductive block 13 on the positioning seat 7 (during manufacturing, an existing annular conductive ring can be fixed on the inner wall of one side of the packaging conveyor 1, and the annular conductive ring can be connected to an external power source, after which...). Several second conductive blocks 13 are attached to an external annular conductive ring to achieve continuous power supply, energizing the electromagnet 15 at the top of the limiting cylinder 14. The electromagnet 15 and the magnet 17 inside the limiting cylinder 14 repel each other due to their like poles, pushing the magnet 17 to slide downward along the limiting cylinder 14. The magnet 17 drives the mounting block 19 downward through the limiting post 16 at the bottom. The positioning block 20 at the bottom of the mounting block 19 then approaches and presses against the edge of the fabric. During this process, the compression spring 18 outside the limiting post 16 is compressed, using elastic buffering to prevent excessive pressure on the positioning block 20. The positioning block 20 contacts the fabric in a flexible pressing manner. This flexible pressing can form a stable pre-positioning for packaging of medium and thick fabrics such as cotton and chemical fibers, avoiding edge friction and fuzzing that would cause exposed rough edges during packaging and ensuring the neatness of the packaging appearance. It can also provide appropriate pressure for light fabrics such as chiffon and lace, which can counteract lateral offset forces without hindering their transmission power, ensuring that the fabric is accurately delivered to the packaging station. This solves the problems of edge damage caused by traditional baffles affecting packaging quality inspection and slippage and accumulation of light fabrics interrupting the packaging production line, and achieves stable transmission that meets the requirements of the packaging process.

[0040] It should also be noted that when the positioning seat 7 leaves the other end of the contact plate 6, the contact roller 10 loses its contact force, the tension spring 37 pulls the sliding plate 8 to reset, the first conductive block 12 and the second conductive block 13 separate, the electromagnet 15 is de-energized, and after the repulsive force disappears, the compression spring 18 pushes the magnet block 17 to move upward, and the limiting post 16 drives the mounting block 19 and the positioning block 20 to detach from the fabric, making it easy to take out the fabric that has been transferred to the designated position, thus completing one pressing and positioning cycle, and the overall use effect is good.

[0041] Example 2: Please refer to Figure 10 - Figure 13This embodiment further describes Example 1. The indentation processing assembly includes a pressure roller 11 and a liquid storage tank 26. The pressure roller 11 is disposed on the side of the sliding plate 8 near the bottom end of the conveyor belt 5, and the liquid storage tank 26 is fixedly installed on the outside of the sliding plate 8 near the top end of the pressure roller 11.

[0042] Two rotating seats 23 are symmetrically fixedly installed on the side of the mounting block 19 near the pressure roller 11. A rotating frame 22 is rotatably installed on one side of each of the two rotating seats 23. The other end of the rotating frame 22 is rotatably installed on the outside of one side of the pressure roller 11. A thin sponge ring 25 is fixedly sleeved through the outside of the pressure roller 11.

[0043] Mounting brackets 21 are fixedly installed on one side of the sliding plate 8 near the middle position of the rotating frame 22. A rotating shaft 24 is fixedly installed on the outside of one side of the mounting bracket 21. The rotating frame 22 is rotatably mounted on the outside of the rotating shaft 24 on the corresponding side at the middle position of one side.

[0044] Specifically, the pressure roller 11 forms a linkage structure with the mounting block 19 through the rotating frame 22. The rotating seat 23 on one side of the mounting block 19 is hinged to one end of the rotating frame 22, and the other end of the rotating frame 22 is hinged to the pressure roller 11. The middle position of the rotating frame 22 is mounted on the mounting frame 21 of the sliding plate 8 through the rotating shaft 24, thereby forming a lever-type transmission.

[0045] An auxiliary frame 27 is fixedly installed on the outside of the liquid storage tank 26 near the bottom end of the pressure roller 11. A liquid collection cylinder 28 is fixedly installed through the inside of the auxiliary frame 27. A one-way liquid inlet valve pipe 29 and a one-way liquid outlet valve pipe 34 are fixedly installed through the top of the liquid collection cylinder 28. The input end of the one-way liquid inlet valve pipe 29 is fixedly installed through the bottom end of the liquid storage tank 26.

[0046] A piston rod 30 is slidably and sealed inside the bottom end of the liquid collecting cylinder 28. A spherical block 31 is fixedly installed at the bottom end of the piston rod 30. A return spring 32 is sleeved on one side of the piston rod 30. The two ends of the return spring 32 are respectively fixedly installed on the outside of the spherical block 31 and the outside of one side of the liquid collecting cylinder 28. A guide pipe 33 is horizontally fixedly installed on the outside of the side of the auxiliary frame 27 near the bottom end of the pressure roller 11.

[0047] The output end of the one-way drain valve pipe 34 is fixedly installed inside one side of the guide pipe 33, and several nozzles 35 are fixedly installed at equal intervals inside the bottom end of the guide pipe 33.

[0048] In this embodiment, when the mounting block 19 presses down on the fabric as the positioning block 20 descends, the rotating frame 22 rotates upward around the rotating shaft 24, causing the pressure roller 11 to lift off the fabric surface simultaneously. This avoids the pressure roller 11 continuously contacting the fabric during the conveying process, effectively preventing secondary indentations caused by long-term friction. When the positioning block 20 is lifted, the rotating frame 22 rotates in the opposite direction, and the pressure roller 11 falls down and adheres to the fabric. At this time, the sliding plate 8 resets and moves, and the pressure roller 11 rolls on the fabric surface to form a rolling action, thereby specifically repairing the marks caused by the positioning block 20 pressing. At the same time, the liquid supply of the storage tank 26 is precisely controlled through the collection cylinder 28 and the piston rod 30: the fabric softener in the storage tank 26 flows into the collection cylinder 28 through the one-way inlet valve pipe 29. When the pressure roller 11 is lifted, the top of the pressure roller 11 will contact the spherical block 31, thereby squeezing the spherical block 31 and lifting it. When the spherical block 31 is lifted, it will push... The piston rod 30 moves inside the liquid collection cylinder 28, thereby squeezing the fabric softener inside the liquid collection cylinder 28 into the one-way drain valve pipe 34. The liquid enters the guide pipe 33 through the one-way drain valve pipe 34, and then is evenly sprayed onto the thin sponge ring 25 on the surface of the pressure roller 11 through the nozzle 35. When the pressure roller 11 falls, the spherical block 31 loses its compression. At this time, the return spring 32 rebounds and pushes the piston rod 30 to return to its original position, so that a negative pressure is generated inside the liquid collection cylinder 28. This allows the liquid that was previously stored in the storage tank 26 to be drawn into the liquid collection cylinder 28 through the one-way inlet valve pipe 29, thus completing the quantitative replenishment of liquid. Ultimately, when the thin sponge ring 25, impregnated with fabric softener, rolls with the pressure roller 11, it softens the fabric fibers through liquid penetration and also uses the sponge's elasticity to buffer the pressure of the roller, achieving a dual repair through physical roller pressure and chemical softening. This effectively eliminates the indentations caused by the positioning block 20 pressing, resulting in a better overall repair effect. It avoids the large-area residue of traditional water spraying that affects the packaging adhesion effect, directly ensuring the flatness of the finished packaging and improving the packaging quality inspection pass rate.
