Technical Field
[0001] The present invention relates to the technical field of recycled materials for non-woven fabric production, and specifically to a recycled material device for non-woven fabric production. Background Art
[0002] Non-woven fabric materials are used in medical and health care, home decoration, clothing, industry, agriculture, etc., and have the advantages of light weight, softness, breathability, good water absorption, etc. When producing non-woven fabrics, large pieces of non-woven fabrics need to be cut to obtain small pieces required for production, and long strip-shaped non-woven fabrics left over from cutting will be generated during production. Non-woven fabrics can be recycled. Therefore, recycling materials in non-woven fabric production also has economic benefits. Recycled material devices for non-woven fabric production are gradually purchased by manufacturers and are widely used in non-woven fabric production and manufacturing enterprises.
[0003] The market is an important criterion for testing products. Some problems that affect production have gradually emerged during the wide application of recycled material devices for non-woven fabric production. The problems are sorted out as follows:
[0004] First: When starting the recycled material work, the staff needs to wind the recycled material around the winding roller, and the winding roller rotates at a low speed, or directly tie it to the collecting shaft. Due to circular motion, the recycled material is prone to idling on the collecting shaft without winding, or during the recycled material process, the recycled material suddenly breaks. The staff approaches the rotating winding roller to pick up the recycled material and then continues production. When approaching the rotating winding roller to pick up the recycled material during work, there is a danger for the staff.
[0005] Second: When collecting the recycled material, there may be differences in the shape and size of the recycled material strips. The discharge speed is the same, and the rotation speed of the collecting shaft is constant, so that different-shaped and sized recycled material strips come into contact. The gaps between different-shaped recycled material strips in contact with each other are always determined by the speed of the collecting shaft and the discharge speed, and neither of them can adjust the gaps for different strip shapes. When winding the recycled material, due to the appearance of different strips, as the winding amount gradually increases, the gaps are also superimposed, resulting in an increase in the part occupied by the gap positions on the collecting shaft, and ultimately reducing the space utilization rate of the collecting shaft.
[0006] Third: When the recycled material is being wound, the collecting shaft rotates continuously. Suddenly, the recycled material strip breaks, and the recycled material strip wound on the collecting shaft gradually returns to the unwound state. For the recycled material strip to return to the unwound state and rewind it onto the collecting shaft increases the time consumption. At the same time, when continuing to wind, the staff ties the recycled material to the collecting shaft and starts collecting the recycled material. Such an operation realizes the superposition and increase of the gaps between the recycled material strips, reducing the space utilization rate of the collecting shaft.
[0007] Fourthly: When collecting the recycled material, when the collecting shaft starts to collect, it mostly starts from the middle position of the collecting shaft. As the recycled material accumulates, the recycled material on the overall collecting shaft shows a state where it is high in the middle and low at both left and right ends. And when the collection of the recycled material is completed, when disassembling the collected recycled material, after the recycled material is disassembled, the internally wound recycled material may return to the unwound state, or it may be difficult to disassemble the recycled material from the collecting shaft.
[0008] To solve the above problems and ensure the improvement of the production capacity of non-woven fabric recycled material collection, a recycled material device for non-woven fabric production is proposed. Summary of the Invention
[0009] The purpose of the present invention is to solve the safety problems of operators, the difficulties in disassembling or uneven distribution of recycled materials, and the low utilization rate of the collecting shaft in the current production of recycled material devices for non-woven fabric production. A recycled material device for non-woven fabric production is provided. By opening a first square hole and a triple square hole on the traction rod and connecting the two inside the traction rod, and setting a rough surface inside the channel, the resistance of different strip-shaped recycled materials on the rough surface is different, realizing the control of the discharging speed of the recycled materials. The speed of the collecting shaft remains unchanged, realizing the automatic adjustment of the distribution of different strip-shaped recycled materials, solving the problems of uneven distribution and low utilization rate of the collecting shaft. A pressure relief groove is installed in cooperation with the limit disk. Utilizing the temperature of the recycled material strip after friction on the rough surface, the recycled material strip is closely attached to the single shaft. After the pressure relief groove is covered by the recycled material strip, a relatively sealed environment is formed. The limit disk controls whether the outside air pressure is connected or disconnected from the pressure relief groove, realizing the removal of the limit disk to connect the atmospheric pressure, so that the air pressure fully squeezes the recycled material strip after winding and facilitates disassembly.
[0010] To achieve the above purpose, the present invention provides the following technical solutions:
[0011] A recycled material device for non-woven fabric production includes a bracket, an electric control box, a winding roller, a motor, a reciprocating screw, a moving square block, and a traction rod. The electric control box is fixedly installed on one side of the bracket. One end of the winding roller is rotatably installed at a position near the top of the electric control box. The motor is fixedly installed at a position near the bottom inside the electric control box. The reciprocating screw is installed between the bracket and the electric control box. The moving square block is installed on the reciprocating screw. One end of the traction rod is installed inside the moving square block. A first square hole is opened at the termination of the movement of the traction rod into the moving square block, and the first square hole is located on the upper side of the traction rod. A triple square hole is opened on the lower side of the traction rod, and the triple square hole is located on the side close to the winding roller. The triple square hole and the first square hole are connected through the inside of the traction rod, and a rough surface is laid between them. The other end of the traction rod is close to the winding roller.
[0012] Preferably, the winding roller includes a collecting shaft and a limit disk. The limit disk is installed at both ends of the collecting shaft. The collecting shaft includes a single shaft and a pressure relief groove. The pressure relief groove is circumferentially and arrayedly opened on the single shaft.
[0013] In the above solution, the collecting shaft is used to collect the returned material. When the single shaft winds the returned material, the returned material with temperature contacts the cold single shaft, and the returned material immediately shrinks. The water vapor in the air near the returned material cools to form water droplets, and the water droplets adhere to the surface where the returned material contacts the single shaft, causing a gap between the returned material and the single shaft, reducing the winding efficiency. A pressure relief groove is provided on the single shaft. When the hot returned material winds around the single shaft, the cooling effect of the hot returned material is reduced. The hot returned material heats the air in the pressure relief groove. At the same time, the returned material that has cooled after contacting the surface of the single shaft adheres to the single shaft and seals the heated gas in the pressure relief groove.
[0014] Preferably, the pressure relief groove is located between the left and right limit disks, and the pressure relief groove extends to the inside of the limit disk and terminates, and is just sealed by the limit disk.
[0015] In the above solution, to solve the problems of the returned material being loose inside the discharge or the discharge not being smooth when discharging the returned material after winding in the prior art, the pressure relief groove is provided to reduce the contact area between the returned material and the single shaft, so that part of the returned material contacts the cold single shaft and immediately shrinks and adheres to the single shaft, and the other part heats the air in the pressure relief groove. The hot air flows along the pressure relief groove. When the entire collecting shaft winds one circle, a space where the pressure relief groove is located is formed. As the single shaft cools, a relatively low-pressure environment is formed, making the returned material closely adhere to the single shaft. The length of the pressure relief groove extends to the installation position of the limit disk to ensure that when the returned material winding ends, removing the limit disk to connect the internal and external air pressures makes it easy to remove the returned material, and at the same time, the internal returned material is not easily loosened after being extruded by the air pressure.
[0016] Preferably, the limit disk includes a single disk and a surrounding hole, and the surrounding holes are circularly arrayed on the single disk.
[0017] In the above solution, to solve the problem that the operator always needs to wind around the shaft when winding the returned material, that is, the possible safety problems in the operation, the single disk is provided with surrounding holes so that the winding can always start from both the left and right ends, that is, when winding the returned material, the phenomenon of being thick in the middle and thin at both ends is reduced, improving the winding efficiency. At the same time, the returned material is stuck in the surrounding holes to start winding the returned material, thus reducing the occurrence of safety problems. By observing the winding situation of the returned material through the surrounding holes, the overall control of the feeding is realized, improving the economic benefits. And when the hot returned material winds to both ends of the collecting shaft, the winding of the returned material is not uneven due to the unsmooth discharge of the air near the side of the returned material disk. At the same time, the dense presence of the surrounding holes reduces the overall mass of the single disk. When collecting the returned material, the swing inertia brought by the collecting shaft is reduced, thus increasing the service life of the equipment.
[0018] Preferably, the surrounding hole is fan-shaped, and the surrounding hole gradually becomes larger from the center position of the self-rotation of the single disk to the peripheral edge of the single disk.
[0019] In the above scheme, when the return material is wound near the limit disk, it is relatively difficult to discharge air on the side close to the limit disk, and the squeezed air will lift up the return material. It is relatively easy to discharge air on the side away from the limit disk. The two sides work together to make the return material winding surface become a curved surface or folded, thereby affecting the efficiency of winding the return material. The annular hole extends to the pressure relief groove to effectively promote the air discharge near the limit disk. The annular hole is set to be fan-shaped because as the winding amount increases, the distance between the three-connected square holes and the axis of the single shaft becomes larger, causing the distance between the starting point of winding and the three-connected square holes to increase, that is, the length of the return material to be wound increases. In order to ensure smooth exhaust, the exhaust hole can only be gradually enlarged to ensure that the return material is not bent or folded when wound on the single shaft.
[0020] Preferably, the installation of the limit plate and the single shaft needs to satisfy that the four pressure relief grooves on the single shaft are matched with the positions on the limit plate where no surrounding holes are provided, and the four pressure relief grooves divide the surrounding holes into four parts.
[0021] In the above scheme, when the single shaft starts to rotate for recovery, the limit plate rotates with the rotation of the single shaft. The rotation of the limit plate accelerates the air flow speed. The air flows in the surrounding hole. Since the surface of the pressure relief groove on the single shaft is not smooth, the air flow is bound to be uneven. Therefore, the pressure relief groove is set opposite to the position where the surrounding hole is not set, so that the air flow exchange between the air in the pressure relief groove and the annular hole is reduced, ensuring that the effect of the pressure relief groove is not affected. The surrounding hole is evenly divided to achieve the same air flow rate in the four evenly divided areas when the motor speed remains unchanged, so that the return material will not be folded or non-planar due to the influence of flow rate and pressure when the area is switched during winding.
[0022] Preferably, the movable block includes a block body and a rod storage hole, the rod storage hole is opened inside the block body and does not pass through the block body, a spring is installed inside the rod storage hole, the spring is connected to the traction rod, a stabilizing upper rod is arranged at one end of the traction rod close to the three-linked square hole, the stabilizing upper rod is not colinear with the traction rod, and the stabilizing upper rod is located at an outer position of the three-linked square hole, and a stabilizing lower rod is arranged at a position symmetrical to the traction rod on the stabilizing upper rod.
[0023] In the above scheme, when the return material is recycled, the rotation of the winding roller drives the wound return material to rotate. Due to the different densities of the return material and the winding roller, there is an axial runout, which causes great wear on the installation position of the winding roller and reduces the service life of the equipment. The design of the stable upper and lower rods converts the jumping impact of the winding roller into the accumulation of elastic potential energy, which plays a role in buffering the jumping of the winding roller, thereby reducing the damage to the installation position of the winding roller caused by the jumping, extending the service life of the equipment. At the same time, the elastic potential energy obtained by the buffering makes the stable upper rod closer to the single axis, which is more conducive to the compaction and recovery of the return material and improves the recycling efficiency.
[0024] Preferably, an upper rod hole is formed in the stable upper rod, and the upper rod hole is located on the surface of the stable upper rod in contact with the winding roller. The upper rod hole, the triple square hole, and the first square hole are internally connected through the traction rod.
[0025] In the above solution, the design of the upper rod hole transfers the heat generated by the friction of the returned material on the rough surface to the returned material through the air acting on the upper rod hole, realizing the simultaneous heating and softening and compaction, improving the winding efficiency. At the same time, the heating of the hot air effectively promotes the elimination of bubbles between the already wound returned materials, reduces the gap between the returned materials, promotes the winding amount of the single shaft, and at the same time utilizes the generated heat to achieve low-energy consumption manufacturing.
[0026] Preferably, a lower rod hole is formed in the stable lower rod, and the lower rod hole is located on the surface of the stable lower rod close to the winding roller. The lower rod hole, the triple square hole, and the first square hole are internally connected through the traction rod. The length of the stable lower rod is half shorter than that of the stable upper rod.
[0027] In the above solution, the extrusion of the returned material by the stable lower rod is not obvious compared with the stable upper rod. However, the returned material always passes through the stable lower rod first and then through the stable upper rod. Therefore, the hot air released from the lower rod hole on the stable upper rod pre-heats and softens the returned material in advance. For the subsequent contact with the stable upper rod, whether it is compaction or softening, there is a good temperature environment. The stable lower rod is relatively shorter because the hot air is lighter and always goes upward. If the stable lower rod is too long, it is not conducive to the discharge of hot air.
[0028] Preferably, the pressure relief groove is located on the winding roller. When the winding roller is not rotating, neither the stable lower rod nor the stable upper rod can contact the pressure relief groove. The installation position of the traction rod needs to be slightly higher than the axis line of the winding roller.
[0029] In the above solution, the stable upper and lower rods are staggered with the pressure relief groove on the winding roller to ensure no abnormal start. At the same time, the static friction force of the pressure relief groove at the start is relatively large, and the rotation will accelerate the wear of the pressure relief groove, which is not conducive to the exertion of the effect of the pressure relief groove on the returned material. The traction rod is installed slightly higher than the winding roller to ensure that when the winding roller jumps, the linearity effect on the traction rod is reduced, and at the same time, the upper and lower rods of the traction rod are evenly stressed, and the stress concentration is dispersed, protecting other parts as much as possible on the premise of extending the service life of the installation position of the winding roller.
[0030] Compared with the prior art, the beneficial effects of the present invention are:
[0031] 1. The present invention realizes different discharging speeds of strip non-woven fabrics with different widths by setting a first square hole and a triple square hole on the towing bar, and setting a rough surface at the position where the first square hole communicates with the triple square hole. Different discharging speeds of the non-woven fabric enable automatic adjustment of the winding gaps of strip non-woven fabrics with different widths when winding on a single shaft. At the same time, the design of the rough surface frictions with the strip non-woven fabric to soften the non-woven fabric. The softening of the non-woven fabric increases the tightness between the strip non-woven fabrics during winding, improves the space utilization rate of the single shaft, and improves the winding efficiency. Meanwhile, the heat generated between the rough surface and the strip non-woven fabric can continue to act on the continuous softening and pre-softening during winding.
[0032] 2. The present invention realizes that the non-woven fabric strip closely adheres to the surface of the single shaft at the beginning of collection by setting a limiting disk and a pressure relief groove in cooperation. When the limiting disk and the pressure relief groove are installed in cooperation, a relatively sealed space is formed between the pressure relief groove and the strip non-woven fabric. As the air in the sealed space cools, the strip non-woven fabric near the pressure relief groove is attracted. When the pressure relief groove and the limiting disk are disassembled, the sealed space is opened, and the air pressure balances to hold the strip non-woven fabric, thus realizing an easy material taking solution. The design of the pressure relief groove ensures that the heated non-woven fabric attached to the cold single shaft will not generate too many bubbles, which affects the winding efficiency of the non-woven fabric.
[0033] 3. The present invention sets a stable upper rod and opens an upper rod hole on the stable upper rod. The design of the upper rod hole realizes the utilization of the heat generated by frictions on the strip non-woven fabric. At the same time, while discharging heat through the upper rod hole, it assists the stable upper rod to compact the strip non-woven fabric. The heat released by the upper rod hole softens the strip non-woven fabric and makes it easier for the stable upper rod to extrude the strip non-woven fabric to remove bubbles and compact more fully.

Specific Embodiments
[0043] Next, the technical solutions of the present invention will be described in detail through the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Compared with the implementation solutions in the present invention, all other solutions obtained by relevant personnel in the art without creative labor fall within the protection scope of the present invention.
[0044] Please refer to Figures 1 to 8 , the present invention provides a recycling equipment for non-woven fabric production, and the technical solutions are as follows:
[0045] As a specific implementation manner of the present invention, referring to Figure 1 , Figure 2 and Figure 3 , a recycling equipment for non-woven fabric production includes a bracket 1, an electric control box 2, a winding roller 3, a motor 4, a reciprocating screw 5, a moving square 6, and a traction rod 7. The electric control box 2 is fixedly installed on one side of the bracket 1. One end of the winding roller 3 is rotatably installed at a position near the top of the electric control box 2. The motor 4 is installed and fixed at a position near the bottom inside the electric control box 2. The reciprocating screw 5 is installed between the bracket 1 and the electric control box 2. The moving square 6 is installed on the reciprocating screw 5. One end of the traction rod 7 is installed inside the moving square 6. At the termination of the movement of the traction rod 7 into the moving square 6, a first square hole 71 is opened, and the first square hole 71 is located on the upper side of the traction rod 7. A triple square hole 72 is opened on the lower side of the traction rod 7, and the triple square hole 72 is located on the side close to the winding roller 3. The triple square hole 72 and the first square hole 71 are connected through the inside of the traction rod 7, and a rough surface 73 is laid between them. The other end of the traction rod 7 is in close contact with the winding roller 3.
[0046] As an implementation manner of the present invention, referring to Figure 4 and Figure 5, the rewinding roller 3 includes a collecting shaft 31 and a limiting disk 32. The limiting disk 32 is installed at both ends of the collecting shaft 31. The collecting shaft 31 includes a single shaft 311 and a pressure relief groove 312. The pressure relief groove 312 is arranged in a circumferential array on the single shaft 311. The pressure relief groove 312 is located between the left and right limiting disks 32 and extends to the inside of the limiting disk 32 and terminates, and is just sealed by the limiting disk 32. The collecting shaft 31 is used to collect the returned material. When the single shaft 311 winds the returned material, the returned material with temperature contacts the cold single shaft 311, and the returned material immediately shrinks. The water vapor in the air near the returned material cools to form water droplets, and the water droplets adhere to the surface where the returned material contacts the single shaft 311, causing a gap between the returned material and the single shaft 311 and reducing the winding efficiency. A pressure relief groove 312 is provided on the single shaft 311. When the hot returned material winds around the single shaft 311, the cooling effect of the hot returned material is reduced. The hot returned material heats the air in the pressure relief groove 312. At the same time, the returned material that has cooled after contacting the surface of the single shaft 311 adheres to the single shaft 311 and seals the heated gas in the pressure relief groove 312. To solve the problems of the returned material being loose inside the unloading or the unloading being not smooth when unloading after the returned material winding is completed in the prior art, the pressure relief groove 312 is provided to reduce the contact area between the returned material and the single shaft 311, so that part of the returned material contacts the cold single shaft 311 and immediately shrinks and adheres to the single shaft 311, and the other part heats the air in the pressure relief groove 312. The hot air flows along the pressure relief groove 312. When the entire collecting shaft 31 winds one circle, a space where the pressure relief groove 312 is located is formed. As the single shaft 311 cools, a relatively low-pressure environment is formed, making the returned material closely adhere to the single shaft 311. The length of the pressure relief groove 312 extends to the installation position of the limiting disk 32 to ensure that when the returned material winding is completed, removing the limiting disk 32 when unloading the returned material connects the internal and external air pressures, making it easy to remove the returned material. At the same time, the internal returned material is not easily loosened after being extruded by the air pressure.
[0047] As an implementation manner of the present invention, referring to Figure 1 , Figure 4 and Figure 5, the limiting disk 32 includes a single disk 321 and a surrounding hole 322. The surrounding holes 322 are circularly arrayed on the single disk 321. To solve the problem that the operator always needs to wind around the axis during the return material winding, that is, the possible safety problems in the operation, the single disk 321 is provided with surrounding holes 322 so that the winding can always start from both the left and right ends. That is, when winding the return material, the phenomenon of thick in the middle and thin at both ends can be reduced, and the winding efficiency can be improved. At the same time, the return material can be stuck in the surrounding holes 322 to start the return material winding, thus reducing the occurrence of safety problems. By observing the situation of the return material winding through the surrounding holes 322, the overall control of the feeding can be realized to improve the economic benefits, and when the hot return material is wound to both ends of the collecting shaft 31, the uneven winding of the return material caused by the unsmooth air discharge near the return material disk side can be avoided. At the same time, the dense existence of the surrounding holes 322 reduces the overall mass of the single disk 321. During the return material collection, the swinging inertia brought by the collecting shaft 31 is reduced, thereby increasing the service life of the equipment. The surrounding holes 322 are fan-shaped, and the single disk 321 gradually becomes larger from the center position of its own rotation to the circular edge of the single disk 321 where the surrounding holes 322 are located. When the return material winds close to the limiting disk 32, it is relatively difficult to discharge air on the side close to the limiting disk 32, and the air being squeezed will lift the return material. The air discharge on the side far from the limiting disk 32 is relatively easy. The combined action of both sides makes the winding surface of the return material become a curved surface or folded, thus affecting the winding efficiency of the return material. The annular hole extends to near the pressure relief groove 312 to effectively promote the air discharge near the limiting disk 32. The annular hole is set as a fan shape because as the winding amount increases, the distance between the three-connected square hole 72 and the axis of the single shaft 311 becomes larger, resulting in an increase in the distance between the starting winding point and the three-connected square hole 72, that is, an increase in the length of the return material to be wound. To ensure the smooth discharge of air, the exhaust hole can only be gradually increased to ensure that the return material is not bent or folded and wound on the single shaft 311. The installation of the limiting disk 32 and the single shaft 311 needs to meet the requirement that the four pressure relief grooves 312 on the single shaft 311 are all matched with the positions on the limiting disk 32 where the surrounding holes 322 are not provided, and the four pressure relief grooves 312 divide the surrounding holes 322 into four equal parts. When the single shaft 311 starts to rotate and recover, the limiting disk 32 rotates with the single shaft 311. The rotation of the limiting disk makes the air flow speed increase. The air flows in the surrounding holes 322. Since the surface of the single shaft 311 is not smooth due to the pressure relief grooves 312 being provided, the air flow is necessarily uneven. Therefore, the pressure relief grooves 312 are arranged facing the positions where the surrounding holes 322 are not provided, so as to reduce the air flow exchange between the air in the pressure relief grooves 312 and the air in the annular holes, ensuring that the function of the pressure relief grooves 312 is not affected. And dividing the surrounding holes 322 equally realizes that under the condition that the speed of the motor 4 remains unchanged, the air flow speeds in the four equal parts areas are the same, so that when the return material is wound, the return material will not be folded or non-planar due to the influence of the flow rate and pressure when switching regions.
[0048] As an implementation manner of the present invention, referring to Figure 1 、 Figure 5 、 Figure 6 andFigure 7 , the moving block 6 includes a block body 61 and a rod storage hole 62. The rod storage hole 62 is opened inside the block body 61 and does not penetrate the block body 61. A spring 8 is installed inside the rod storage hole 62, and the spring 8 is connected to the traction rod 7. A stable upper rod 74 is provided at one end of the traction rod 7 close to the triple square hole 72. The stable upper rod 74 is not collinear with the traction rod 7 and is located outside the triple square hole 72. A stable lower rod 75 is provided at a position symmetric to the traction rod 7 with respect to the stable upper rod 74. When recycling the returned material, the winding roller 3 rotates to drive the wound returned material to rotate. Due to the different densities of the returned material and the winding roller 3, there is an axial jump, which causes large wear on the installation position of the winding roller 3 and reduces the service life of the equipment. The design of the stable upper and lower rods converts the jump impact of the winding roller 3 into the accumulation of elastic potential energy, which buffers the jump of the winding roller 3, thereby reducing the damage to the installation position of the winding roller 3 and extending the service life of the equipment. At the same time, the elastic potential energy obtained by buffering makes the stable upper rod 74 better close to the single shaft 311, which is more conducive to compacting and recycling the returned material and improving the recycling efficiency.
[0049] As an embodiment of the present invention, referring to Figure 1 and Figure 7 , an upper rod hole 741 is opened on the stable upper rod 74, and the upper rod hole 741 is located on the surface of the stable upper rod 74 in contact with the winding roller 3. The upper rod hole 741, the triple square hole 72, and the first square hole 71 are internally connected through the traction rod 7. A lower rod hole 751 is opened on the stable lower rod 75, and the lower rod hole 751 is located on the surface of the stable lower rod 75 close to the winding roller 3. The lower rod hole 751, the triple square hole 72, and the first square hole 71 are internally connected through the traction rod 7. The length of the stable lower rod 75 is half shorter than the length of the stable upper rod 74. The design of the upper rod hole 741 transfers the heat generated by the friction of the returned material on the rough surface 73 to the returned material through the air in the upper rod hole 741, realizing simultaneous heating, softening, and compaction, improving the winding efficiency. At the same time, the heating of the hot air effectively promotes the elimination of bubbles between the already wound returned materials, reduces the gap between the returned materials, promotes the winding amount of the single shaft 311, and utilizes the generated heat to achieve low-energy consumption manufacturing.
[0050] As an embodiment of the present invention, referring to Figure 1 , Figure 4 , Figure 7, the extrusion of the returned material by the stable lower rod 75 is not obvious compared to the stable upper rod 74. However, the returned material always passes through the stable lower rod 75 first and then through the stable upper rod 74. Therefore, the lower rod hole 751 on the stable upper rod 74 releases hot air to preheat and soften the returned material in advance. For the subsequent contact of the stable upper rod 74, whether it is compaction or softening, it has a good temperature environment. The stable lower rod 75 is relatively shorter because hot air is lighter and always rises. If the stable lower rod 75 is too long, it is not conducive to the discharge of hot air. The pressure relief groove 312 is located on the winding roller 3. When the winding roller 3 is not rotating, neither the stable lower rod 75 nor the stable upper rod 74 can contact the pressure relief groove 312. The installation position of the traction rod 7 needs to be slightly higher than the axis line of the winding roller 3. The stable upper and lower rods are staggered with the pressure relief groove 312 on the winding roller 3 to ensure no abnormal start. At the same time, the static friction force for starting by the pressure relief groove 312 is relatively large, and rotation will accelerate the wear of the pressure relief groove 312, which is not conducive to the exertion of the effect of the pressure relief groove 312 on the returned material. The traction rod 7 is installed slightly higher than the winding roller 3 to ensure that when the winding roller 3 jumps, the linearity effect on the traction rod 7 is reduced. At the same time, the upper and lower rods of the traction rod 7 are evenly stressed, and the stress concentration is dispersed, protecting other parts as much as possible on the premise of extending the service life of the installation position of the winding roller 3.
[0051] Workflow: The electric control box 2 is powered on, the motor 4 is started, the motor 4 drives the winding roller 3 to rotate, and the single shaft 311 on the winding roller 3 starts to collect strip-shaped non-woven fabric. The strip-shaped non-woven fabric enters through the rough surface 73 from the first square hole 71, and then the strip-shaped non-woven fabric passes through the three square holes on the triple square hole 72 from left to right in sequence. The strip-shaped non-woven fabric passes through two adjacent holes of the surrounding hole 322. Here, there is a prerequisite that the traction rod 7 must be started close to the limit disc 32. The strip-shaped non-woven fabric is squeezed with the rough surface 73 to generate heat, and this heat heats the non-woven fabric. The non-woven fabric is softened. The movement direction of the non-woven fabric drives the heat flow, and the heat flows along the inside of the traction rod 7 and is released at the upper rod hole 741 and the lower rod hole 751. After heating, the non-woven fabric strip starts to wind around the single shaft 311. The hot non-woven fabric strip contacts and releases heat at the position where the single shaft 311 does not have the pressure relief groove 312 and then adheres to the single shaft 311. The place where the non-woven fabric covers the pressure relief groove 312 heats the air in its space. When the winding of the non-woven fabric satisfies that the moving block 6 has completed a round trip on the reciprocating screw 5, the inside of the pressure relief groove 312 becomes a closed small space and is filled with hot air. As the number of wound non-woven fabric strips increases, the internal hot air cools down and the air pressure decreases, causing the non-woven fabric strips close to the pressure relief groove 312 to be tightly sucked. When the winding of the non-woven fabric strip ends, the limit disc 32 is disassembled, and the sealed environment where the pressure relief groove 312 is located is connected. The previously attracted non-woven fabric strips are opened, making it easier to disassemble the wound non-woven fabric strips.
[0052] When the winding roller 3 rotates to collect the non-woven fabric strip, the upper rod holes 741 formed in the stable upper rod 74 continuously release heat, which acts on the wound non-woven fabric strip, making the non-woven fabric strip soften and adhere better to the single shaft 311. At the same time, the stable upper rod 74 squeezes the possible air bubbles in the non-woven fabric. Due to the presence of heat, the air bubbles are easily squeezed and the gap between the non-woven fabric strips is reduced. At the same time, the lower rod holes 751 formed in the stable lower rod 75 release heat to soften the upper layer of non-woven fabric strip that has been wound, providing a good working environment for the winding and compaction of the next layer. As the winding amount on the single shaft 311 increases, the non-woven fabric strip pushes the traction rod 7 inward, making the traction rod 7 always close to the non-woven fabric strip. During the winding operation, the winding effect can be observed through the surrounding hole 322 to realize the speed adjustment of the winding roller 3.
