At the same time, when cutting off, the heat-sealing mechanism synchronously melts and seals the cut of the woven fabric to prevent the fibers from spreading or burrs from generating, ensuring that the cut is flat and sealed.

Through the mutual cooperation of the two tension rollers, the adapted arc-shaped plates, and several springs, the present invention adaptively adjusts the tension of the woven fabric, avoiding the problem of uneven tightness of the initial woven fabric roll, ensuring the winding quality. At the same time, through the cooperation of the first soft brush and the second soft brush, the upper and lower surfaces of the woven fabric can be simultaneously rotated and cleaned, effectively removing the plastic debris remaining on the surface of the woven fabric, avoiding impurities from being embedded in the bag body and affecting the appearance or functionality.

Detailed implementation mode

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0034] Example 1, as Figure 1 shown, a plastic woven bag winding device includes an operating platform 1. The rear side of the upper end of the operating platform 1 is rotatably connected with an original winding roller 2. The rear side of the upper end of the operating platform 1 in front of the original winding roller 2 is rotatably connected with a cleaning mechanism 3. Two tension adjusting mechanisms 5 are rotatably connected to the upper end of the operating platform 1. The middle part of the upper end of the operating platform 1 is rotatably connected with a flattening mechanism 4. The front side of the upper end of the operating platform 1 is rotatably connected with a winding mechanism 9. The lower end of the operating platform 1 below the winding mechanism 9 is fixedly connected with a shrinking mechanism 8. The rear side of the upper end of the operating platform 1 behind the shrinking mechanism 8 is fixedly connected with a heat sealing mechanism 7. The rear side of the upper end of the operating platform 1 behind the heat sealing mechanism 7 is fixedly connected with a static elimination mechanism 6.

[0035] After the plastic woven bag is woven, the woven bag roll is an initial roll with a relatively large radius. In order to facilitate subsequent printing, film laminating and the needs of different customers, the initial roll needs to be rewound into woven bag rolls with different radii.

[0036] The initial woven bag roll is fixed by the cooperation of the original winding roller 2. Subsequently, through the cooperation of the tension adjusting mechanism 5 located at the rear and the cleaning mechanism 3, the tension of the woven fabric is first adjusted to ensure that the woven fabric is evenly stressed during the subsequent winding process. At the same time, the upper and lower surfaces of the woven fabric are cleaned by the cleaning mechanism 3 to remove the plastic debris remaining on the surface of the woven fabric, avoiding the influence of debris and other sundries on the subsequent operation of the woven fabric;

[0037] Meanwhile, through the combined action of the flattening mechanism 4 and the tension adjusting mechanism 5 located at the front side of the upper end of the operating table 1, the surface of the woven bag is made flat, reducing unevenness caused by the weaving process or tension fluctuations. At the same time, the tension of the woven fabric is adjusted again to compensate for material shrinkage or extension that may occur during heating and ironing, ensuring that the tension is suitable during winding. Further, through the cooperation of the static elimination mechanism 6 and the winding mechanism 9, the operation of eliminating static electricity is carried out while winding, avoiding the situation of interlayer adhesion during winding;

[0038] During the winding process with the cooperation of the winding mechanism 9, the height of the shrinking mechanism 8 is set by presetting the winding radius. When the winding radius is about to reach the preset radius, the outermost side of the wound woven fabric will continuously press down on the shrinking mechanism 8 during the rotational winding process. At the same time, the shrinking mechanism 8 and the heat sealing mechanism 7 cooperate with each other to automatically heat seal and cut off the woven fabric when the winding mechanism 9 reaches the set winding radius, avoiding the problem of uneven cut ends after winding.

[0039] During the operation of this embodiment, through the sequential operation and cooperation of the cleaning mechanism 3, the flattening mechanism 4, the two tension adjusting mechanisms 5, and the static elimination mechanism 6, the initial woven fabric is subjected to treatments such as tension adjustment, cleaning, ironing, secondary tension adjustment, and static elimination, significantly improving the surface smoothness and antistatic performance of the woven fabric. At the same time, the heat sealing mechanism 7 synchronously melts and seals the cut end of the woven fabric during cutting to prevent fiber dispersion or burr generation, ensuring that the cut end is flat and sealed. Through the combined operation of the winding mechanism 9, the shrinking mechanism 8, and the heat sealing mechanism 7, the high-precision and high-efficiency of the winding process are achieved.

[0040] Embodiment 2. On the basis of Embodiment 1, this embodiment aims to achieve the effect of a wound woven fabric roll with no static adhesion, clean and flat surface, and appropriate tension.

[0041] Refer to Figure 2 , the cleaning mechanism 3 includes a motor 31 fixedly connected to the rear side of the upper end of the operating table 1. The output end of the motor 31 is fixedly connected with a guide roller 33. The left side of the outer surface of the guide roller 33 is drivingly connected with a guide roller 32, the left side of the outer surface of the guide roller 33 is drivingly connected with a soft brush 34, and the left side of the outer surface of the soft brush 34 is drivingly connected with a soft brush 35.

[0042] The above-mentioned driving connections are all carried out by common belt pulleys in the prior art.

[0043] When the initial woven fabric roll is rewound, during the process of preparing to wind the woven fabric, by activating the operation of the first motor 31, the output end of the first motor 31 drives the second guide roller 33 to rotate continuously. Then, through the cooperation of the first guide roller 32 and the second guide roller 33, the woven fabric is guided. During the rotation of the second guide roller 33, the first soft brush 34 and the second soft brush 35 will rotate simultaneously. The first soft brush 34 and the second soft brush 35 rotate and clean the upper and lower surfaces of the woven fabric at the same time, removing the residual plastic debris on the surface of the woven bag and preventing impurities from embedding into the bag body and affecting the appearance or functionality.

[0044] Refer to Figure 3 , the tension adjusting mechanism 5 includes a third motor 51 slidably connected to the upper end of the operating table 1. The output end of the third motor 51 is fixedly connected with a tension roller 52. Arc-shaped plates 53 are symmetrically arranged on the outer surface of the tension roller 52. A plurality of springs 54 are annularly arranged on the outer arc surfaces of the two arc-shaped plates 53. A plurality of springs 54 on the same side are jointly fixedly connected with a support plate 55.

[0045] The tension adjusting mechanism 5 located at the rear side of the upper end of the operating table 1, during the winding process, through the operation of the third motor 51, the output end of the third motor 51 drives the tension roller 52 to rotate continuously, and at the same time, the tension of a plurality of springs 54 is adjusted in advance. In this way, when the woven fabric passes through the upper part of the outer surface of the first guide roller 32, the lower part of the outer surface of the tension roller 52, and the upper part of the outer surface of the second guide roller 33 in sequence, through the joint cooperation of a plurality of springs 54 and the arc-shaped plates 53, when the tension of the woven fabric is insufficient, at this time, the tension roller 52 and the third motor 51 as a whole press down on the woven fabric, and at the same time, the two arc-shaped plates 53 cooperate with a plurality of springs 54 to be compressed, increasing the tension of the woven fabric. When the tension of the woven fabric is too large, it will push up the tension roller 52 and the third motor 51. At this time, a plurality of springs 54 and the arc-shaped plates 53 are no longer squeezed, and at this time, the tension of the woven fabric is released;

[0046] Through the mutual cooperation of the tension roller 52, a plurality of springs 54, and the arc-shaped plates 53, during the process of the first guide roller 32 and the second guide roller 33 guiding the woven fabric to move forward, the tension of the woven fabric is automatically adjusted to avoid the situation of uneven tightness of the initial woven fabric roll.

[0047] After the woven fabric whose surface tension is automatically adjusted by the tension roller 52 located at the rear side of the upper end of the operating table 1 passes through the upper part of the outer surface of the second guide roller 33, it passes through between the first soft brush 34 and the second soft brush 35. At this time, the first soft brush 34 and the second soft brush 35 are running continuously, cleaning the plastic debris on the upper and lower surfaces of the woven fabric.

[0048] Refer to Figure 4, the flattening mechanism 4 includes a second motor 41 fixedly connected to the middle of the upper end of the operating table 1. The output end of the second motor 41 is fixedly connected with a first pressure roller 42. The left side of the outer surface of the first pressure roller 42 is drivingly connected with a third guide roller 43. The left side of the outer surface of the first pressure roller 42 is drivingly connected with a first heating roller 44. The left side of the outer surface of the first heating roller 44 is drivingly connected with a second heating roller 46. The left side of the outer surface of the first heating roller 44 is drivingly connected with a second pressure roller 45.

[0049] The above-mentioned first heating roller 44 and second heating roller 46 are common technical means for heating and ironing plastic woven bags in the prior art. Heating tubes commonly used in the prior art are provided inside the first heating roller 44 and the second heating roller 46. During the process of winding the woven fabric, the heating tubes are activated, causing the temperatures of the first heating roller 44 and the second heating roller 46 to rise, which can iron the upper and lower surfaces of the woven fabric. At the same time, the temperatures of the first heating roller 44 and the second heating roller 46 will not melt the fibers of the woven bag. The temperatures of the first heating roller 44 and the second heating roller 46 can only iron the surface of the woven fabric.

[0050] The cleaned woven fabric passes through the lower part of the outer surface of the second pressure roller 45, between the first heating roller 44 and the second heating roller 46, and the lower part of the outer surface of the first pressure roller 42 in sequence, and then passes through the upper part of the outer surface of the third guide roller 43 to prepare for subsequent operations.

[0051] During the winding process, by activating the second motor 41, the output end of the second motor 41 drives the first pressure roller 42 to rotate. Subsequently, through the driving connection of pulleys in the prior art, the third guide roller 43, the first heating roller 44, the second pressure roller 45, and the second heating roller 46 rotate simultaneously.

[0052] During the rotation of the second pressure roller 45 and the third guide roller 43, pressure can be evenly applied to the woven fabric. During the rotation, each part of the second pressure roller 45 and the third guide roller 43 can come into contact with the woven fabric in sequence, enabling the woven fabric to be uniformly stressed in both the width and length directions, so as to better cooperate with the first heating roller 44 and the second heating roller 46 to achieve a more uniform ironing effect.

[0053] After being heated and ironed, the woven fabric enters the lower part of the outer surface of the tension roller 52 located on the front side of the upper end of the operating table 1 under the guidance of the third guide roller 43. Through the cooperation of the tension roller 52 located on the front side, two arc-shaped plates 53, and several springs 54, it is possible to compensate for the material shrinkage or extension that may occur during the heating and ironing process, ensuring that the tension of the woven fabric is appropriate during winding and preventing the phenomenon of being too tight or too loose.

[0054] Refer to Figure 5, the static elimination mechanism 6 includes a first metal roller 61 fixedly connected to the upper end of the operating table 1, and a second metal roller 62 fixedly connected to the upper end of the operating table 1 below the first metal roller 61. The right ends of the first metal roller 61 and the second metal roller 62 are fixedly connected to a wire 63, and the lower end of the wire 63 is connected to the ground.

[0055] After adjusting the tension of the woven fabric again, it passes between the first metal roller 61 and the second metal roller 62, and the upper and lower surfaces of the woven fabric are in contact with the first metal roller 61 and the second metal roller 62 respectively. During the weaving process and the cleaning and ironing processes of the woven fabric, due to the characteristics of plastics, static electricity will be generated on the woven fabric, resulting in the phenomenon of interlayer adhesion. At the same time, the wire 63 mentioned above is always connected to the ground. When static electricity accumulates on the surface of the woven fabric, it can be connected to the ground through the first metal roller 61 or the second metal roller 62 and then through the wire 63. At this time, the ground can neutralize the static electricity on the surface of the woven fabric, avoiding the situation that the woven fabric is not smoothly wound due to carrying static electricity during winding.

[0056] Refer to Figure 6 , the winding mechanism 9 includes a winding roller 92 rotatably connected to the front side of the upper end of the operating table 1, and a fourth motor 91 is arranged at the right end of the winding roller 92.

[0057] Similarly, when preparing for winding, by activating the fourth motor 91 to run, the winding roller 92 rotates continuously to wind the woven fabric. When the radius of the woven fabric wound on the outer surface of the winding roller 92 reaches the preset value, by pausing the operation of the fourth motor 91, the first motor 31, the second motor 41, etc., the winding roller 92 and the wound woven fabric are removed, and then a new winding roller 92 is replaced to make the winding roller 92 be fixedly clamped to the output end of the fourth motor 91, and winding is carried out again.

[0058] Therefore, in this solution, through the mutual cooperation of the two tension rollers 52, the adapted arc-shaped plates 53 and several springs 54, the tension of the woven fabric is adaptively adjusted, avoiding the problem of uneven tightness of the initial woven fabric roll, ensuring the winding quality. At the same time, through the cooperation of the first soft brush 34 and the second soft brush 35, the upper and lower surfaces of the woven fabric can be rotated and cleaned simultaneously, effectively removing the plastic debris remaining on the surface of the woven fabric, avoiding impurities from being embedded in the bag body and affecting the appearance or functionality. At the same time, through the operation and mutual cooperation of each structure in the flattening mechanism 4, the tension adjusting mechanism 5 and the static elimination mechanism 6, a woven fabric roll with no static adhesion, clean surface, ironed flat and appropriate tension is realized, facilitating subsequent operations such as printing and storage.

[0059] Embodiment 3, on the basis of Embodiment 1 and 2, to achieve the effect of heat-sealing and truncating the woven fabric during the process of the winding roller 92 winding the woven fabric approaching the end.

[0060] Refer to Figure 7 and Figure 8, the contraction mechanism 8 includes a telescopic cylinder 81 fixedly connected to the front side of the upper end of the operation table 1. A roller 82 is rotatably connected to the upper side of the inner surface of the telescopic cylinder 81. Two air bags three 87 are symmetrically and fixedly connected to the bottom wall of the inner surface of the telescopic cylinder 81. Two air bags four 88 are symmetrically and fixedly connected to the middle of the bottom wall of the inner surface of the telescopic cylinder 81. The two air bags three 87 on the same side are jointly fixedly connected to a second pipeline 84. One end of the second pipeline 84 far from the two air bags three 87 is fixedly connected to an air bag one 85. The two air bags four 88 on the same side are jointly fixedly connected to a first pipeline 83. One end of the first pipeline 83 far from the two air bags four 88 is fixedly connected to an air bag two 86. The roller 82 is located directly below the winding roller 92.

[0061] Furthermore, when the winding roller 92 is about to start winding, and for the radius of the woven fabric to be wound by the winding roller 92, by inflating the four air bags three 87 and the four air bags four 88, at this time, the internal air pressures of the two air bags three 87, the adapted second pipeline 84, and the air bag one 85 are in balance. When the air bags three 87 and the air bags four 88 are squeezed, the gas inside the air bags three 87 and the air bags four 88 cannot go out through the inflation port, and can only enter the air bag two 86 through the first pipeline 83, or enter the air bag one 85 through the second pipeline 84.

[0062] Furthermore, during the process of the winding roller 92 continuously rotating to wind the woven fabric, when the radius of the woven fabric wound by the winding roller 92 is about to reach the set radius, at this time, the lowest point of the woven fabric wound on the outer surface of the winding roller 92 starts to contact the upper part of the outer surface of the roller 82. During the process of the radius of the woven fabric wound on the outer surface of the winding roller 92 continuously increasing, it will continuously squeeze the roller 82 downward. At the same time, due to the rotation of the winding roller 92, the roller 82 is rotated while being squeezed downward;

[0063] During the process of the roller 82 descending, it will squeeze the four air bags three 87 and the four air bags four 88, and at the same time, the telescopic cylinder 81 is driven to contract.

[0064] When the four air bags three 87 and the four air bags four 88 are simultaneously squeezed by the roller 82, at this time, the gas inside the two air bags three 87 on the same side enters the air bag one 85 through the second pipeline 84, and at this time, the air bag one 85 continuously expands;

[0065] Similarly, when the two air bags four 88 on the same side are squeezed, the gas inside the two air bags four 88 enters the air bag two 86 through the first pipeline 83, and at this time, the air bag two 86 continuously expands.

[0066] Refer to Figures 9 - 11, the heat-sealing mechanism 7 includes fixing plates 71 symmetrically and fixedly connected to the upper end of the operating table 1. On the upper parts of the sides of the two fixing plates 71 close to each other, first telescopic tubes 72 are fixedly connected. On the middle parts of the sides of the two fixing plates 71 close to each other, second telescopic tubes 73 are fixedly connected. The lower ends of the two first telescopic tubes 72 are jointly fixedly connected to a cross plate 75. In the middle of the lower end of the cross plate 75, a rectangular plate 78 is fixedly connected. On the outer surface of the rectangular plate 78, a first heat-sealing plate 76 is arranged. At the lower end of the rectangular plate 78, a cutting knife 79 is fixedly connected. The upper ends of the two second telescopic tubes 73 are jointly fixedly connected to a second heat-sealing plate 77. At the left end of the right fixing plate 71, a heat-sealing controller 74 is fixedly connected.

[0067] During the continuous inflation of the two second air bags 86 and the two first air bags 85, through the arrangement between the first telescopic tubes 72 adapted to the second air bags 86 and the second telescopic tubes 73 adapted to the first air bags 85 respectively, the bottom wall of the inner surface of the first telescopic tube 72 is pushed downward by the inflated second air bag 86, and the top wall of the inner surface of the second telescopic tube 73 is pushed upward by the inflated first air bag 85.

[0068] Furthermore, during the downward pushing of the lower ends of the two first telescopic tubes 72, the cross plate 75, the rectangular plate 78, the cutting knife 79 and the first heat-sealing plate 76 are driven to move downward simultaneously. Similarly, during the upward pushing of the upper ends of the two second telescopic tubes 73, the second heat-sealing plate 77 will be driven to move upward synchronously.

[0069] Refer to Figure 10 and Figure 11 , the top wall of the inner surface of the first telescopic tube 72 is fixedly connected to the upper part of the outer surface of the second air bag 86. The bottom wall of the inner surface of the second telescopic tube 73 is fixedly connected to the lower part of the outer surface of the first air bag 85. In the middle of the right end of the left fixing plate 71, a baffle 711 is fixedly connected. At the lower right side of the right end of the right first telescopic tube 72, a pressing plate 721 is slidably connected. The upper end of the heat-sealing controller 74 is electrically connected to a key 741. The first heat-sealing plate 76 and the second heat-sealing plate 77 are jointly electrically connected to the heat-sealing controller 74. Two rectangular grooves 781 are respectively opened at the left end and the right end of the rectangular plate 78. On the left side wall and the right side wall of the inner surface of the first heat-sealing plate 76, two sliding blocks 761 are fixedly connected respectively. The two sliding blocks 761 on the same side are respectively slidably connected to the inner surface of the adapted rectangular groove 781.

[0070] Furthermore, during the process of the horizontal plate 75, the first heat-sealing plate 76, and the rectangular plate 78 being driven downward, at this time, the lower end of the pressing plate 721 is driven by the lower end of the first telescopic tube 72 to descend simultaneously. Immediately, the lower end of the pressing plate 721 contacts the upper end of the key 741. At this time, the pressing plate 721 presses the key 741, and the heat-sealing controller 74 is activated through the key 741. As a result, the first heat-sealing plate 76 and the second heat-sealing plate 77 operate simultaneously. At this time, the first heat-sealing plate 76 and the second heat-sealing plate 77 heat the upper and lower surfaces of the woven fabric. At the same time, since the distance between the first heat-sealing plate 76 and the second heat-sealing plate 77 from the woven fabric is relatively far, when the first heat-sealing plate 76 and the second heat-sealing plate 77 are just activated, the temperature at this time will not affect the woven fabric.

[0071] Furthermore, during the process of the two first telescopic tubes 72 continuing to push the horizontal plate 75 downward, at this time, the upper end of the baffle 711 contacts the lower end of the first heat-sealing plate 76. At this time, the baffle 711 prevents the first heat-sealing plate 76 from continuing to descend. As a result, during the process of the rectangular plate 78 continuing to drive the cutter 79 downward, the two sliders 761 on the same side slide upward on the inner surface of the adapted rectangular groove 781. At the same time, the first heat-sealing plate 76 continues to heat the surface of the woven fabric, and at the same time, the pressing plate 721 and the key 741 continue to be in close contact, and the pressing plate 721 slides upward along the right end of the first telescopic tube 72.

[0072] When the first heat-sealing plate 76 is blocked by the baffle 711 and no longer continues to descend, at this time, the two second telescopic tubes 73 continue to push the second heat-sealing plate 77 upward, and at the same time, the two first telescopic tubes 72 push the horizontal plate 75, the rectangular plate 78, and the cutter 79 downward simultaneously.

[0073] When the radius of the woven fabric wound on the outer surface of the winding roller 92 reaches the preset value, at this time, the roller 82 presses the telescopic cylinder 81 to descend to the lowest point, and at the same time, the lower end of the cutter 79 is in close contact with the upper end of the second heat-sealing plate 77. At this time, the cutter 79 cuts off the melted woven fabric to prevent burrs and other situations from occurring at the cut-off part of the woven fabric.

[0074] At the same time, in the above process, from the moment when the woven fabric wound on the winding roller 92 is about to reach the preset radius and presses the roller 82 to descend, to the moment when the woven fabric wound on the outer surface of the winding roller 92 reaches the preset radius and the cutter 79 cooperates with the second heat-sealing plate 77 to cut off the woven fabric, this process takes a short time. That is, the shorter section of the woven fabric will be heated and melted by the first heat-sealing plate 76 and the second heat-sealing plate 77.

[0075] After removing the wound winding roller 92 and the woven fabric and storing them, a new winding roller 92 is put in again for winding. At the same time, the first airbag 85 and the second airbag 86 are used to reset the third airbag 87 and the fourth airbag 88.

[0076] The heat-sealing plate 1 76, heat-sealing plate 2 77, and heat-sealing controller 74 in the above are common heat-sealing means in the prior art. When the button 741 is pressed, the heat-sealing controller 74 can be triggered to operate. Then, through electrical connection, the heat-sealing plate 1 76 and the heat-sealing plate 2 77 start heating simultaneously.

[0077] Similarly, during the process of removing the wound-up winding roller 92 and replacing it with a new one to prepare for winding, the temperatures of the heat-sealing plate 1 76 and the heat-sealing plate 2 77 will quickly return to the normal temperature state, without affecting the next winding process.

[0078] Therefore, this solution utilizes the phenomenon that the radius of the woven fabric wound by the winding roller 92 continuously increases. During the increasing process, in cooperation with the airbag 3 87, airbag 4 88, airbag 1 85, and airbag 2 86, the telescopic tube 1 72 and the telescopic tube 2 73 are used to realize the sequential actions of the heat-sealing plate 1 76, the heat-sealing plate 2 77, and the cutting knife 79. The heat-sealing plate 1 76 and the heat-sealing plate 2 77 first heat the woven fabric, and then the cutting knife 79 cuts the woven fabric. The whole process is rapid and coherent, which can not only ensure that the cut of the woven fabric is heat-sealed, avoiding burrs, looseness, etc. at the cut of the truncated woven fabric, but also quickly complete the winding and truncation processes, and prepare for the next winding.
