Description

Technical Field

[0001] This invention relates to the field of coiling machine technology, and more particularly to a feeding guide device for a coiling machine. Background Technology

[0002] In the processing and production of materials such as textiles, films, and paper, winding machines are key equipment for winding and sorting materials. They use rotating rollers to wind continuously conveyed materials into regular rolls for subsequent storage, transportation, and further processing. The feeding stage of the winding machine, as the starting step of the entire winding process, directly affects the winding quality and production efficiency.

[0003] The winding machine consists of a feeding mechanism, a conveying and guiding assembly, a winding mechanism, and a power control system. During operation, the material to be wound (such as textile fabrics, films, and paper) is released from the feeding mechanism, and after its posture and tension are adjusted by the conveying and guiding assembly, it is conveyed to the winding mechanism. The core of the winding mechanism is the winding roller, which is driven to rotate by a motor. The material is continuously wound onto the roller using the friction between the material and the roller surface or a preset tension device.

[0004] Currently, the feeding process of traditional fabric rolling machines relies heavily on manual assistance. When a roll of fabric is finished and a new roller needs to be changed, the worker first pulls the old roller, which is fully wrapped with fabric, out of the rolling machine's workstation. Then, the end of the fabric wrapped around the old roller is cut off with a tool. Next, the new roller is moved to the designated position and temporarily placed. The fabric to be rolled is then manually flattened and arranged to remove wrinkles. Any knots left from the previous rolling are then cut off to ensure the starting end of the fabric is flat. After these preparations, the worker pulls the starting end of the fabric around the surface of the new roller, repeatedly adjusting it to align the fabric edges and ensure the edges are parallel to the roller's axis. Finally, the new roller with the fabric starting end is placed in the rolling machine's processing position and initially secured with a fixing device. Before starting the machine, workers need to quickly smooth the fabric using the initial power to ensure it is evenly wound onto the new roller. However, this method poses a safety hazard. Throughout the feeding process, workers' hands must continuously pull the end of the fabric, and to ensure accurate winding onto the roller, their hands must be close to the roller, which is either preparing to rotate or already starting to rotate at low speed—often only a few centimeters away. If the machine starts accidentally or the roller speed suddenly increases, hands can easily be caught between the roller and the fabric, causing injury. Therefore, a feeding guide device for the winding machine needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 , Figure 6 and Figures 8-9 As shown, this embodiment of the invention provides a feeding and guiding device for a rolling machine, including a rolling component 1 fabric. The rolling component 1 fabric is supported by a processing table 11 fabric. An inclined guiding surface 12 fabric is provided on the processing table 11. Gravity is used to assist in the fabric conveying, which is in line with the actual production operation habit of moving fabric, rolls and other materials from high to low. One end of the guide surface 12 is rotatably equipped with a guide roller 121. The rotation of the roller reduces the friction of the fabric conveying process, allowing the fabric to smoothly enter the processing flow. A fixing frame 15 is installed on the side of the fabric 11 on the processing table. A guide roller 151 is installed on the fixing frame 15 via bearings. The guide roller 151 cooperates with the guide roller 121 to form a multi-roller conveying path, further standardizing the direction of the fabric. A guide frame 16 is configured above the fabric 151 on the processing table 11 to limit the fabric in space and prevent it from shifting or wrinkling during transport. At the same time, a drive roller 17 is added above the guide frame 16. The active rotation of the drive roller provides power for the fabric transport, adapting to the traction needs of fabrics of different thicknesses and materials. This solves the problem of transport stalling or slipping caused by excessively heavy or thick fabrics in actual production. Through the combination of multiple guide structures and power rollers, the feeding process of the winding machine is ensured to be efficient and stable, improving the overall continuity of the winding operation and the quality of the finished product. To ensure the conveying and winding of the fabric during the rolling operation, a drive unit 14 is provided on the side of the processing table 11 away from the guide frame 16. The drive unit 14 is used to provide rotational power for the winding roller of the fabric, and the drive unit 14 is supported by a concave auxiliary table 141. The auxiliary table 141 is adapted to the working layout of the processing table 11 and provides a stable installation space for the drive structure. Within the grooved space of the auxiliary platform 141, drive roller 142 and drive roller 143 are mounted via bearings. The distance between the two rollers is set to form a double-roller cooperative structure for clamping and rotation, which can adapt to rolls of different diameters and ensure that the rolls do not deviate during conveying and winding. In actual production, the roller shaft ends of drive roller 142 and drive roller 143 are driven by a motor and gear set. The motor output power is transmitted through the gear set to drive the two drive rollers to rotate synchronously, flexibly adapting to the winding operation of fabrics with different thicknesses and tension requirements. To further improve the conveying stability of the roller on the drive unit 14 and avoid the roller from deviating or shaking during the winding operation, which would affect the fabric winding quality, a clamping part 13 is provided in the groove space of the auxiliary table 141 between the drive roller 142 and the drive roller 2 143. The clamping part 13 is used to limit the roller, and the clamping part 13 includes a guide rod 131 that is fixedly installed in the groove space of the auxiliary table 141 and is in a horizontal state, so as to provide a linear motion reference for the clamping assembly 2. Two sets of guide sleeves 132 are mounted on the guide rod 131. The guide sleeves 132 can slide smoothly along the guide rod 131. Vertically arranged clamping plates 133 are fixedly installed on the guide sleeves 132. The two clamping plates 133 cooperate to form clamping limits from both sides of the roll, which can be adapted to rolls of different lengths. In actual production, the guide sleeves 132 can be slid according to the roll size to adjust the distance between the two clamping plates 133, flexibly meeting the limit requirements of rolls of various specifications, and solving the problems of winding deviation and fabric wrinkling caused by insufficient roll limit in traditional winding machines.

[0023] To fix the adjustment position of the clamping plate 133 and ensure the stability of the limit during the winding operation, a slide rod 134 (at least one set) parallel to the guide rod 131 is fixedly installed in the groove space of the auxiliary table 141, on one side of the drive roller 142 and the drive roller 2 143. A movable sleeve 135 is slidably assembled on the slide rod 134, and the movable sleeve 135 is locked and fixed to the slide rod 134 by a butterfly nut 136. Meanwhile, a connecting rod 137 is vertically inserted through the clamping plate 133, with one end of the connecting rod 137 fixedly connected to the movable sleeve 135. After adjusting the spacing of the clamping plates 133, the wing nut 136 is tightened, and the movable sleeve 135 is fixed on the slide rod 134. The clamping plate 133 is pulled by the connecting rod 137 to maintain the predetermined position, ensuring that the roll is always within the limit range of the two clamping plates 133 during the conveying and winding process of the drive roller 142 and drive roller 2 143, thereby improving the stability of the rolling operation and the quality of the finished product, and meeting the requirements of the textile, packaging and other industries for the precision of roll material processing.

[0024] Thus, the rolling machine achieves stable fabric conveying through a multi-layered guiding structure and power transmission. The inclined guiding surface 12 of the processing table 11 uses gravity to assist in the fabric conveying. The first guide roller 121 and the second guide roller 151 reduce friction by rotating. They work with the guide frame 16 to limit the space. The third drive roller 17 actively rotates to provide traction. The multi-component collaboration standardizes the fabric direction, ensures the conveying power, adapts to different fabric characteristics, and solves the problems of conveying stagnation and slippage. The concave auxiliary platform 141 of the drive unit 14 supports drive roller 142 and drive roller 143. A motor and gear set drive the two rollers to rotate, forming a clamping and conveying structure that adapts to different rolls. The clamping unit 13 adjusts the spacing of the clamping plates 133 with the help of guide rods 131 and guide sleeves 132 to adapt to the length of the roll. The sliding rod 134, movable sleeve 135 and wing nut 136 are locked in place, and the connecting rod 137 pulls the clamping plates 133 to fix them, ensuring that the roll conveying and winding do not deviate, improving the rolling stability and finished product quality, and meeting the industry's processing precision requirements.

[0025] To smooth the fabric on the inclined guide surface 12 and prevent one end of the fabric from becoming loose after a set of rollers has been wound, thus avoiding wrinkles on the inclined guide surface 12, such as... Figures 3-5 As shown, a smoothing component 2 is provided on the processing table 11. The smoothing component 2 includes two sets of base frames 21 fixedly installed on both sides of the processing table 11, and a driving part 14 is provided between the two sets of base frames 21. The driving part 14 includes a concave frame 22 provided between the two sets of base frames 21. The concave frame 22 and the guide surface 12 have the same inclination to adapt to the fabric conveying path. Meanwhile, a bidirectional lead screw 23 is mounted on the concave frame 22 with bearings. The bidirectional lead screw 23 has two sets of helical grooves with opposite directions of rotation. Guide rods 24 are fixedly mounted on the concave frame 22 and located on both sides of the bidirectional lead screw 23. Lead screw sleeves 25 are threadedly connected to both sets of helical grooves. The lead screw sleeves 25 are slidably mounted on the two sets of guide rods 24. A motor 218 is fixedly mounted on one end of the concave frame 22. The motor 218 is connected to one end of the bidirectional lead screw 23 through a coupling. The motor 218 is adapted to drive the bidirectional lead screw 23 to rotate, so as to drive the two sets of lead screw sleeves 25 to move closer or further apart. Furthermore, a smoothing part is installed between the two sets of base frames 21. The smoothing part includes a straight rod 29 fixedly installed between the two sets of base frames 21 and directly below the concave frame 22. Two sets of pressure rollers 210 with a spacing are slidably installed on the straight rod 29. At the same time, the pressure rollers 210 have through holes larger than the diameter of the straight rod 29 (not shown in the figure) so that they can slide flexibly along the straight direction of the straight rod 29. The two sets of pressure rollers 210 are respectively connected to two sets of lead screw sleeves 25 through hinge seats 211. By moving the lead screw sleeves 25, the spacing of the pressure rollers 210 is adjusted. Furthermore, a pressure roller 2 is fixedly installed at the center of the straight rod 29. The pressure roller 2 is in contact with the fabric on the guide surface 12, and plays a role in positioning and assisting in flattening. In the initial state, the two sets of pressure rollers 210 are close together and in contact with the fabric. When the roll is finished winding the fabric and then cut, the fabric becomes loose and tends to wrinkle. The motor 218 drives the bidirectional lead screw 23 to rotate, and the lead screw sleeve 25 drives the pressure roller 210 to slide along the straight rod 29. At this time, the two sets of pressure rollers 210 move away from each other to dynamically smooth the fabric on the inclined guide surface 12, solve the wrinkling problem caused by the loose fabric in traditional rolling machines, ensure the flatness of the fabric conveying, improve the quality of the rolled product, and meet the requirements of the textile, printing and other industries for the flatness of the roll surface. Meanwhile, to prevent the fabric on the guide surface 12 from wrinkling again when the two sets of pressure rollers 210 move close to the two ends of the concave frame 22 for reset, continue to refer to... Figures 4-5 As shown, two sets of inclined grooves 221 are provided on the concave frame 22, which are arranged oppositely and inclined upward. A slider 222 is slidably arranged in the inclined groove 221, and a lifting ring 26 is threadedly connected to the slider 222. Meanwhile, a connecting rod 27 is fixedly installed on the pressure roller 210. One end of the connecting rod 27 has an electromagnet 28, which passes through the lifting ring 26 and is restricted by the lifting ring 26. A limiting block 219 is fixedly installed on the connecting rod 27. The limiting block 219 is close to the side of the lifting ring 26 away from the electromagnet 28. At the same time, a concave rod 212 is fixedly installed on the side of the concave frame 22. A sliding sleeve 213, the same number as the lead screw sleeve 25, is movably sleeved on the concave rod 212. A lifting ring 214 is threaded on the sliding sleeve 213. An elastic rope 215 is sleeved on the lifting ring 214. One end of the elastic rope 215 has an electromagnet 217. In the initial state, the electromagnet 217 is not connected to the electromagnet 28. At this time, the lower end of the magnet 28 is close to one side of the lifting ring 26 under the action of the gravity of the holding wheel 210. At this time, the limiting block 219 and the other side of the lifting ring 26 have a small gap. Furthermore, a limiting ring 216 is provided on the side of the sliding sleeve 213 near the concave frame 22. One end of the elastic rope 215 passes through the limiting ring 216, and the electromagnet 217 at one end of the elastic rope 215 is restricted by the limiting ring 216. At the same time, a switch (not shown in the figure) is provided at the end of the two sets of inclined grooves 221 that are close to each other. The switch is used to control the corresponding electromagnet to be de-energized. A switch is provided at the end of the two sets of inclined grooves 221 that are far apart from each other. The switch is used to control the corresponding electromagnet to be energized. In the initial state, when slider 222 presses switch one, the electromagnet is de-energized. When slider 222 moves to the far end of inclined groove 221 due to lead screw sleeve 25, switch two energizes the electromagnet. At this time, electromagnet one 28 and electromagnet two 217 attract each other. Electromagnet one pulls limit block 219, causing pressure roller one 210 to rotate around hinge seat 211. At this time, pressure roller one 210 does not contact the fabric. Because the through hole of pressure roller one 210 is larger than the diameter of straight rod 29, there is no interference during rotation. The pressing angle and force can be dynamically adjusted to adapt to complex situations such as tension changes and loosening differences caused by fabric winding. The combined design of electromagnets, mechanical limiters, and switch controls enables the pressure roller 210 to have active angle adjustment capabilities, solving the problem that traditional fixed pressure structures cannot handle dynamic wrinkles. This further improves the smoothing effect of the fabric on the inclined guide surface 12, ensuring that the fabric is always flat during the rolling operation. It is suitable for the extreme requirements of high-precision roll material processing for fabric flatness. From the perspective of detailed structural optimization, it enhances the practicality and stability of the smoothing component 2.

[0026] To achieve guidance and roller changing connection at the fabric winding end, such as Figures 6-8 As shown, a guide assembly 3 is configured on the slide bar 134, and its structure is designed around the coordinated functions of fabric clamping, conveying, and roller changing. The guide assembly 3 includes a number of sleeves 31 that match the number of movable sleeves 135. The sleeves 31 are movably sleeved on the slide bar 134, and the sleeves 31 are linked to the movable sleeves 135 through a linkage rod 33 to ensure that the guide assembly 3 adjusts its position synchronously with the clamping part 13. A right-angle tube 32 is fixed on the sleeve 31. The right-angle tube 32 has a hollow horizontal end 34 with a through groove (not shown in the figure). A motor 36 is fixed to one end of the horizontal end 34. The motor 36 is connected to a lead screw 35 via a coupling. The lead screw 35 extends into the horizontal end 34 and is connected to the inner wall bearing, providing a power source for the movable sleeve 37. The movable sleeve 37 is movably fitted on the horizontal end 34. The movable sleeve 37 has a protrusion that fits the groove and is threadedly connected to the lead screw 35, allowing it to slide along the horizontal end 34. A pipe clamp 38 is fixed on the movable sleeve 37. Pneumatic grippers 39 are installed on the opposite side of the two sets of pipe clamps 38. The gripper heads move symmetrically. A clamping rod 310 is connected between the two sets of horizontally symmetrical gripper heads of the two sets of pneumatic grippers 39. In the initial state, there is a gap between the two clamping rods 310 for the fabric to pass through. A support end 311 is fixedly installed on the side of the pipe clamp 38. A rotating roller 312 is provided between the bearings of the support ends 311 to form a clamping and supporting fabric conveying structure to ensure the stability of the fabric guiding path. Furthermore, a pressure sensor (not shown in the figure) is installed at the contact position between the clamping rod 310 and the fabric to detect changes in fabric tension in real time. At the same time, a PLC control system is configured on the processing table 11 to coordinate the operation of the equipment. When a set of rollers has finished winding and the fabric is cut, the pressure sensor detects that the pressure has decreased. The PLC control system triggers the two sets of pneumatic grippers 39 to start synchronously. The gripper heads drive the clamping rod 310 to clamp the fabric, ensuring that the fabric end is accurately gripped. This solves the tedious problem of manually pulling the fabric when changing rollers in the traditional way and realizes the automation of roller changing.

[0027] After the pressure sensor triggers the clamping, motor 2 36 starts, driving screw 1 35 to rotate. This drives the moving sleeve 37 from its initial position near the movable sleeve 135, sliding along the waist groove of the horizontal end 34 to the other end. The moving sleeve 37, through the pipe clamp 38 and pneumatic gripper 39, pulls the fabric end held by the clamping rod 310 to move directly above the drive roller 142, preparing for the feeding of the new roll. This process utilizes the precision of the screw drive to ensure accurate fabric end delivery position, adapting to the requirements of the rolling machine for roll changing connection precision, and avoiding problems such as uneven winding and uneven tension caused by fabric offset.

[0028] Once the fabric end is in place, the operator places the new roll between drive roller 142 and drive roller 243, ensuring it adheres to the surfaces of both rollers and holds the fabric end in place. The PLC then controls the pneumatic gripper 39 to loosen, and the clamping rod 310 no longer holds the fabric. The fabric is then wound around the surface of the new roll. Finally, drive rollers 142 and 143 are activated, using the rotation of the two rollers to drive the new roll to rotate, completing the fabric winding and roll change. The entire process is highly automated, reducing manual intervention and improving the continuity and efficiency of the winding operation.

[0029] During the winding operation, the fabric follows a fixed guide path. One end first lies flat against the guide surface 12, then passes the upper end of the guide roller 121, the bottom surface of the drive roller 2 143, and then the upper surface of the rotating roller 312, through the gap between the two sets of clamping rods 310, and finally winds onto the winding roller. The rotating roller 312 is mounted on a bearing at the support end 311 and rotates flexibly with the fabric conveying, reducing friction. The clamping rods 310 always maintain the gap for the fabric to pass through, ensuring continuous conveying of the fabric throughout the roller changing and winding process, without jamming or wrinkling due to the movement of the guide assembly 3, thus ensuring the quality of the finished winding product.

[0030] The guiding component 3, through its fully automated design encompassing detection, clamping, conveying, and roller changing, addresses the pain points of difficult fabric alignment and cumbersome manual operation during roller changes in winding machines. A pressure sensor and PLC work together to achieve intelligent triggering, a screw drive ensures positional accuracy, pneumatic grippers 39 and clamping rods 310 precisely control the fabric end, and rotating rollers 312 assist in conveying, adapting to the winding needs of fabrics of different thicknesses and materials. Whether performing continuous single-roll winding or multi-roll roller changing operations, it ensures stable fabric conveying and neat winding, improving the overall operating efficiency and finished product quality of the winding machine, and meeting the automated production needs of large-scale roll material processing in industries such as textiles and packaging.

[0031] Working principle: The inclined guide surface 12 of the processing table 11 uses gravity to assist in the transfer of fabric. The first guide roller 121 and the second guide roller 151 reduce friction by rotating. The guide frame 16 limits the space. The third drive roller 17 actively rotates to provide traction. The multi-component cooperation standardizes the direction of the fabric, ensures the conveying power, adapts to different fabric characteristics, and solves the problems of conveying stagnation and slippage. The concave auxiliary platform 141 of the drive unit 14 supports the first drive roller 142 and the second drive roller 143. The motor and gear set drive the double rollers to rotate to form a clamping and conveying structure, which is suitable for different rolls. The clamping unit 13 adjusts the spacing of the clamping plate 133 with the help of the guide rod 131 and the guide sleeve 132. The sliding rod 134, the movable sleeve 135 and the wing nut 136 lock the position. The connecting rod 137 pulls the clamping plate 133 to fix it, ensuring that the roll conveying and winding do not deviate, improving the rolling stability and the quality of the finished product.

[0032] The smoothing component 2 works in conjunction with the smoothing part via the drive unit 14. The concave frame 22 is inclined at the same angle as the guide surface 12. The bidirectional lead screw 23 and the guide rod 24 work together with the lead screw sleeve 25 to drive the pressure roller 210 to slide along the straight rod 29. In the initial state, the two sets of pressure rollers 210 are close together and in contact with the fabric. When the roll cuts the fabric and it comes loose, the motor 218 drives the bidirectional lead screw 23 to rotate, and the pressure rollers 210 move away from each other to dynamically smooth the fabric. At the same time, the inclined groove 221 and the slider 222 of the concave frame 22 work together with the electromagnet and switch control to enable the pressure roller 210 to have active angle adjustment capability, solving the drawbacks of the traditional fixed pressure structure, ensuring that the fabric is always flat during transport, and adapting to the needs of high-precision roll material processing.

[0033] The guide component 3 is designed around the roller changing connection. The sleeve 31 adjusts its position synchronously with the clamping part 13. The horizontal end 34 of the right-angle tube 32 is driven by the second motor 36 and the first lead screw 35 to slide the moving sleeve 37. The pneumatic gripper 39 and the clamping rod 310 work with the pressure sensor and the PLC control system to realize fabric cutting detection and automatic clamping. After the pressure sensor is triggered, the second motor drives the moving sleeve 37 to move the fabric end to directly above the first drive roller 142. After the operator places the new roll and holds the fabric end, the pneumatic gripper 39 loosens, and the drive roller is started to complete the winding. The whole process is automated, reducing manual intervention and improving the roller changing connection accuracy and operation efficiency.

[0034] The winding machine's feeding and guiding device works in concert with three major systems: feeding and conveying, fabric smoothing, and roller changing, forming a complete operational process of stable conveying, dynamic smoothing, and roller changing. The multi-layered guiding structure adapts to different fabrics and rollers, the smoothing component solves the problem of dynamic wrinkles, and the guiding component 3 automates roller changing. All systems are linked through mechanical structures, sensors, and a PLC to ensure smooth fabric conveying and neat winding, meeting the automation and high-precision requirements of large-scale roll material processing in industries such as textiles and packaging, and improving the overall efficiency and quality of the winding operation.
