Description

Technical Field

[0001] The invention belongs to the technical field of winding and collecting plastic ziplock bags, and in particular relates to a winding device for producing plastic ziplock bags. Background Art

[0002] Plastic ziplock bags are a common type of packaging and storage product. They are characterized by a reusable sealing structure (such as a pressing strip, a zipper, etc.) designed at the bag opening, which is convenient for multiple uses. The production process is to first prepare PP or PE materials and other materials into long strips of film tape, which are letterpress printed and dried during the conveying process, and then the printed and dried film tape is rolled up to facilitate the next step of three-side sealed bags and back-sealed bags. In the prior art, when producing plastic ziplock bags, the film tape needs to be centrally wound and rewound. After the winding is completed, the winding roller with the film tape wrapped around it needs to be manually removed and transported to a shelf or a transfer vehicle. This operation method is labor-intensive and has a long downtime that affects production efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a ziplock bag winding device with a quick replacement winding roller.

[0004] The technical solution adopted to solve the above technical problems is: a winding device for producing plastic ziplock bags, including a winding work frame, and a winding roller conduction frame and a linkage conductor for inductively removing the electrostatic adsorption roller are arranged on one side of the winding work frame.

[0005] Through the above technical scheme, the winding work frame can provide a platform for winding the ziplock bag film. The electrostatic adsorption roller can make the wound ziplock bag film stick to the outside of the electrostatic adsorption roller through the principle of electrostatic adsorption to avoid looseness. The end position of the ziplock bag film raw material can be adhered and fixed after the electrostatic adsorption roller is automatically removed. When the ziplock bag film is rolled to a specified thickness, it is sensed by the linkage conductor, causing the electrostatic adsorption roller to be removed.

[0006] The lower surface of the winding work frame is located below the winding roller guide frame and is fixedly connected with an arc guide bin, and the arc guide bin is arranged in an arc shape close to the electrostatic adsorption roller.

[0007] Through the above technical scheme, the arc-shaped guide bin can conduct the unloaded electrostatic adsorption roller, so that the electrostatic adsorption roller is unloaded to the position below the equipment, which is convenient for transportation by forklift and reduces the labor intensity of handling. The arc-shaped arc-shaped guide bin makes the unloading of the electrostatic adsorption roller smoother.

[0008] Furthermore, the winding roller conductive frame includes two symmetrically arranged conductive frame bodies, a conductive groove is opened at the middle position of one side of the two conductive frame bodies close to each other, a limiting sliding groove is opened between one side of the two conductive frame bodies and the conductive groove, and fixed through holes are opened on both sides of the conductive frame bodies.

[0009] Through the above technical scheme, the main body of the conductive frame provides limit support for the electrostatic adsorption roller, and performs upper and lower limit transmission of the electrostatic adsorption roller to realize the installation and removal of the electrostatic adsorption roller, the electrostatic adsorption roller rotates in the conductive groove, and the arc-shaped blocking block slides in the limit slide position. When the arc-shaped blocking block slides out from the limit slide position, the electrostatic adsorption roller wraps around the ziplock bag film. When the arc-shaped blocking block is in the limit slide, the electrostatic adsorption roller is prevented from sliding and being intercepted. The fixed through hole allows the winding roller conductive frame to be installed and fixed on the winding work frame.

[0010] Furthermore, the two conductive frame bodies are penetrated by fixed through holes and fixed to the two sides of the winding work frame by bolts. The conductive frame body is located on the inner wall of the conductive groove and is embedded and rotatably connected to an embedded rotating disk. The embedded rotating disk is fixedly connected to a power transmission block in the middle of one side close to the middle of the winding work frame.

[0011] Through the above technical solution, the embedded rotating disk can fix the power transmission block and transmit power to the electrostatic adsorption roller, so that the electrostatic adsorption roller rotates to achieve the winding of the ziplock bag film, and the power transmission block can position the two ends of the electrostatic adsorption roller.

[0012] Furthermore, a reduction motor is fixedly connected to one side of the winding work frame through a support frame, and a synchronous pulley is fixedly connected to the driving end of the reduction motor and the center position of the side wall of the inlaid rotating disk at the corresponding position, and a synchronous conveyor belt is arranged between the two synchronous pulleys.

[0013] Through the above technical solution, the reduction motor provides power for the rotation of the synchronous pulley, and the synchronous transmission belt can transmit power to the synchronous pulley at the position of the embedded rotating disk, and then transmit the power to the electrostatic adsorption roller through the embedded rotating disk and the power transmission block.

[0014] Furthermore, the linkage conductor includes two symmetrically arranged arc-shaped blocking blocks, the two arc-shaped blocking blocks are slidably connected to the limiting sliding grooves at the corresponding positions, the side walls of the two arc-shaped blocking blocks are fixedly connected with adjustment slides, the side positions of the adjustment slides are penetrated with adjustment grooves, and an induction adjustment rod is arranged between the two adjustment slides, the induction adjustment rod is arranged in a "U" shape and the two ends are slidably connected to the adjustment slide.

[0015] Through the above technical solution, when the arc-shaped blocking block is in the limit sliding groove, it can longitudinally block the conduction groove, so that the electrostatic adsorption roller will not slide off from the position of the conduction groove, and the electrostatic adsorption roller can rotate and wind normally. A scale line is arranged on the side position of the adjusting slide plate. The adjusting slide plate and the induction adjusting rod slide relative to each other, and the winding amount can be effectively adjusted to adapt to self-sealing bag films of different models.

[0016] Further, tightening butterfly bolts are arranged through the two ends of the induction adjusting rod, and the tightening butterfly bolts pass through the through adjusting grooves, and the adjusting slide plate and the induction adjusting rod are fixed by tightening the butterfly bolts.

[0017] Through the above technical solution, when the relative positions of the induction adjusting rod and the adjusting slide plate are adjusted, they can be tightened and fixed by tightening the butterfly bolts. Under the action of the tightening butterfly bolts, the induction adjusting rod will not fall off from the position of the adjusting slide plate through the through adjusting grooves.

[0018] Further, spring telescopic rods are fixedly connected to one side of each of the two conduction frame bodies close to the limit sliding groove, and a reset induction block is fixedly connected to the telescopic end of the spring telescopic rod.

[0019] Through the above technical solution, the spring telescopic rod can apply pressure to the reset induction block, so that the arc-shaped blocking block is tightly pressed into the limit sliding groove, making the operation of the electrostatic adsorption roller more stable. When the thickness of the self-sealing bag film wound on the electrostatic adsorption roller increases, the induction adjusting rod is extruded outwards.

[0020] Further, the electrostatic adsorption roller includes an outer roller body. Side protection plates are arranged at both ends of the outer roller body. An electrostatic roller body is fixedly connected to the middle position of the inner wall of the outer roller body. Plug heads are slidably connected to the openings at both ends of the outer roller body, and the plug heads are fixedly connected to the side protection plates.

[0021] Through the above technical solution, the outer roller body is the main body for winding. After the electrostatic roller body is charged and started, the self-sealing bag film can be wound by electrostatic adsorption. After the electrostatic adsorption roller is removed, the broken end of the winding can be fixed with tape, and the plug head can block both ends of the outer roller body.

[0022] Further, sliding adjustment grooves are opened on the outer sides of the plug heads. Two symmetrically arranged power adjustment blocks are slidably connected to the positions of the sliding adjustment grooves. Reset springs are fixedly connected between the two power adjustment blocks and the inner walls of the sliding adjustment grooves. Two symmetrically arranged sliding fixing grooves are opened at the positions of the inner walls of both ends of the outer roller body corresponding to the sliding adjustment grooves, and the power adjustment blocks are slidably connected to the inner walls of the corresponding sliding fixing grooves.

[0023] Through the above technical solution, the sliding adjustment groove enables the power adjustment block to be conveniently adjusted. The return spring can pull the power adjustment block, so that the power adjustment block can be inserted into the sliding fixing groove to fix the plug and the power adjustment block at the position of the outer roller body. When the power adjustment block is pushed in the middle, the power adjustment block slides out of the sliding fixing groove, and the plug together with the side protection plate can be removed, facilitating the removal of the wound self-sealing bag film.

[0024] Furthermore, a winding auxiliary roller is arranged on one side of the winding working frame away from the winding roller conduction frame. A plurality of uniformly distributed fixed support columns are fixedly connected to the edge position of the lower surface of the winding working frame. Two symmetrically arranged limit fixing feet are fixedly connected to both sides of the bottom of the arc-shaped guiding bin. An intercepting door is arranged between the two limit fixing feet. A guiding conical bin is fixedly connected to the top positions of the two winding roller conduction frames, and the outlet of the guiding conical bin is aligned with the position of the conduction groove.

[0025] Through the above technical solution, the winding auxiliary roller can support the self-sealing bag film to be wound. The fixed support columns support the entire winding working frame. The limit fixing feet can fix the intercepting door. When the intercepting door is lifted upwards, the wound self-sealing bag film can be forked out in the arc-shaped guiding bin. The intercepting door prevents the electrostatic adsorption roller from rushing out of the arc-shaped guiding bin.

[0026] The beneficial effects of the present invention are as follows: By setting the winding roller conduction frame and the linkage conductor, when winding the self-sealing bag film, as the winding thickness of the self-sealing bag film at the position of the electrostatic adsorption roller increases, the arc-shaped blocking block of the linkage conductor disengages from the limit sliding groove, so that the electrostatic adsorption roller automatically slides down under the action of gravity. The electrostatic adsorption roller at the upper position slides to the position of the limit sliding groove, completing the automatic unloading of the electrostatic adsorption roller without the need for shutdown, improving the winding efficiency of the self-sealing bag, and no manual intervention is required when the electrostatic adsorption roller is unloaded, reducing the labor intensity of the construction.

Detailed implementation mode

[0036] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] As Figure 1-8 shown, a winding device for producing plastic self-sealing bags in this embodiment includes a winding working frame 1. A winding roller conduction frame 7 and a linkage conductor 10 for inductively removing the static adsorption roller 11 are arranged at one side of the winding working frame 1. The winding working frame 1 can provide a platform for winding the self-sealing bag film. The static adsorption roller 11 can make the wound self-sealing bag film adhere to the outside of the static adsorption roller 11 by the principle of static adsorption, avoiding looseness. After the static adsorption roller 11 is automatically removed, the end position of the self-sealing bag film raw material can be adhered and fixed. When the self-sealing bag film is wound to a specified thickness, it is sensed by the linkage conductor 10, causing the static adsorption roller 11 to be removed.

[0038] On one side of the coiling workbench 1 away from the coiling roller conduction frame 7, there is a coiling auxiliary roller 2. At the edge position of the lower surface of the coiling workbench 1, several uniformly distributed fixed support columns 6 are fixedly connected. At both sides of the bottom of the arc-shaped guiding bin 5, two symmetrically arranged limit fixing feet 3 are fixedly connected. Between the two limit fixing feet 3, there is an intercepting door 4. At the top positions of the two coiling roller conduction frames 7, a guiding conical bin 8 is fixedly connected, and the outlet of the guiding conical bin 8 is aligned with the conduction slot 71. The coiling auxiliary roller 2 can support the self-sealing bag film to be coiled. The fixed support columns 6 support the whole coiling workbench 1. The limit fixing feet 3 can fix the intercepting door 4. When the intercepting door 4 is lifted upwards, the coiled self-sealing bag film can be forked out in the arc-shaped guiding bin 5. The intercepting door 4 prevents the static electricity adsorption roller 11 from rushing out of the arc-shaped guiding bin 5.

[0039] The linkage conductor 10 includes two symmetrically arranged arc-shaped blocking blocks 105. The two arc-shaped blocking blocks 105 are slidably connected through the corresponding position limit sliding grooves 75. At the side wall positions of the two arc-shaped blocking blocks 105, an adjusting slide plate 103 is fixedly connected. A through adjusting groove 106 is penetrated and opened at the side position of the adjusting slide plate 103. Between the two adjusting slide plates 103, there is an induction adjusting rod 100. The induction adjusting rod 100 is arranged in a "U" shape and the two ends are slidably connected with the adjusting slide plate 103. When the arc-shaped blocking block 105 is in the limit sliding groove 75, it can longitudinally block the conduction slot 71, so that the static electricity adsorption roller 11 will not slide down from the conduction slot 71, and the static electricity adsorption roller 11 can rotate and coil normally. Scale lines are arranged at the side position of the adjusting slide plate 103. The adjusting slide plate 103 and the induction adjusting rod 100 slide relatively, and the coiling amount can be effectively adjusted to adapt to self-sealing bag films of different models.

[0040] On one side of the two conduction frame bodies 70 close to the limit sliding groove 75, spring telescopic rods 104 are fixedly connected. At the telescopic end position of the spring telescopic rod 104, a reset induction block 102 is fixedly connected. The spring telescopic rod 104 can apply pressure to the reset induction block 102, so that the arc-shaped blocking block 105 is tightly pressed into the limit sliding groove 75, making the operation of the static electricity adsorption roller 11 more stable. When the thickness of the self-sealing bag film wound on the static electricity adsorption roller 11 increases, the induction adjusting rod 100 is extruded outwards.

[0041] At the two ends of the induction adjusting rod 100, tightening butterfly bolts 101 are penetrated and arranged, and the tightening butterfly bolts 101 pass through the through adjusting groove 106. The adjusting slide plate 103 and the induction adjusting rod 100 are fixed by the tightening butterfly bolts 101. When the relative positions of the induction adjusting rod 100 and the adjusting slide plate 103 are adjusted, they can be tightened and fixed by the tightening butterfly bolts 101. Under the action of the tightening butterfly bolts 101, the induction adjusting rod 100 will not fall off from the adjusting slide plate 103 through the through adjusting groove 106.

[0042] On one side of the coiling workbench 1, a reduction motor 9 is fixedly connected through a support frame. The driving end of the reduction motor 9 and the center position of the side wall of the corresponding inlaid rotating disc 74 are both fixedly connected with synchronous belt pulleys 12. A synchronous conveyor belt 13 is arranged between the two synchronous belt pulleys 12. The reduction motor 9 provides power for the rotation of the synchronous belt pulley 12, and the synchronous conveyor belt 13 can transmit the power to the synchronous belt pulley 12 at the position of the inlaid rotating disc 74, and then transmit the power to the electrostatic adsorption roller 11 through the inlaid rotating disc 74 and the power transmission block 73.

[0043] The coiling roller conduction frame 7 includes two symmetrically arranged conduction frame bodies 70. A conduction groove 71 is opened in the middle position of the side of the two conduction frame bodies 70 close to each other. A limiting chute 75 is penetrated and opened between one side of the two conduction frame bodies 70 and the conduction groove 71. Fixing through holes 72 are penetrated and opened on both sides of the conduction frame body 70. The conduction frame body 70 limits and supports the electrostatic adsorption roller 11, and conducts up and down limit transmission on the electrostatic adsorption roller 11 to realize the installation and removal of the electrostatic adsorption roller 11. The electrostatic adsorption roller 11 rotates in the conduction groove 71, and the arc-shaped blocking block 105 slides at the position of the limiting chute 75. When the arc-shaped blocking block 105 slides out from the position of the limiting chute 75, the electrostatic adsorption roller 11 winding the self-sealing bag film is intercepted. When the arc-shaped blocking block 105 is in the limiting chute 75, the electrostatic adsorption roller 11 is prevented from slipping. The fixing through holes 72 enable the coiling roller conduction frame 7 to be installed and fixed on the coiling workbench 1.

[0044] The two conduction frame bodies 70 and the two sides of the coiling workbench 1 are penetrated through the fixing through holes 72 and fixed by screwing bolts. An inlaid rotating disc 74 is inlaid and rotatably connected at the inner wall position of the conduction groove 71 of the conduction frame body 70. A power transmission block 73 is fixedly connected to the middle of the side of the inlaid rotating disc 74 close to the middle of the coiling workbench 1. The inlaid rotating disc 74 can fixedly install the power transmission block 73 and transmit the power to the electrostatic adsorption roller 11, so that the electrostatic adsorption roller 11 rotates to realize the coiling of the self-sealing bag film, and the power transmission block 73 can position both ends of the electrostatic adsorption roller 11.

[0045] The lower surface of the coiling workbench 1 is fixedly connected with an arc-shaped guiding bin 5 at the position below the coiling roller conduction frame 7. One side of the arc-shaped guiding bin 5 close to the electrostatic adsorption roller 11 is arc-shaped. The arc-shaped guiding bin 5 can conduct the removed electrostatic adsorption roller 11, so that the electrostatic adsorption roller 11 is unloaded to the position below the equipment, which is convenient for forklift transportation, reduces the labor intensity of handling, and the arc-shaped guiding bin 5 with an arc-shaped setting makes the unloading of the electrostatic adsorption roller 11 more stable.

[0046] The electrostatic adsorption roller 11 includes an outer roller body 110. Side protection plates 111 are provided at both ends of the outer roller body 110. In the middle position of the inner wall of the outer roller body 110, an electrostatic roller body 113 is fixedly connected. Plug heads 117 are slidably connected to the open positions at both ends of the outer roller body 110, and the plug heads 117 are fixedly connected to the side protection plates 111. The outer roller body 110 serves as the main body for winding. After the electrostatic roller body 113 is charged and started, the self-sealing bag film can be wound and wrapped by means of electrostatic adsorption. After the electrostatic adsorption roller 11 is removed, the broken end of the winding can be fixed with tape. The plug heads 117 can block both ends of the outer roller body 110.

[0047] Sliding adjustment grooves 115 are provided on the outer sides of the plug heads 117. Two symmetrically arranged power adjustment blocks 112 are slidably connected to the positions of the sliding adjustment grooves 115. A return spring 116 is fixedly connected between the two power adjustment blocks 112 and the inner wall of the sliding adjustment groove 115. At both ends of the inner wall of the outer roller body 110, two symmetrically arranged sliding fixing grooves 114 are provided at the positions of the sliding adjustment grooves 115, and the power adjustment blocks 112 are slidably connected to the inner walls of the corresponding sliding fixing grooves 114. The sliding adjustment grooves 115 facilitate the adjustment of the power adjustment blocks 112. The return spring 116 can pull the power adjustment blocks 112, so that the power adjustment blocks 112 can be inserted into the sliding fixing grooves 114 to fix the plug heads 117 and the power adjustment blocks 112 in the outer roller body 110. When the power adjustment blocks 112 are pushed in the middle, the power adjustment blocks 112 slide out of the sliding fixing grooves 114, and the plug heads 117 together with the side protection plates 111 can be removed, facilitating the removal of the wound self-sealing bag film.

[0048] The working principle of this embodiment is as follows. When in use, the conveyed self-sealing bag film is passed through the upper position of the winding auxiliary roller 2 and pulled to the position of the electrostatic adsorption roller 11. The electrostatic roller body 113 is started to generate an electrostatic adsorption force on the outside of the outer roller body 110. The deceleration motor 9 is started, and the power of the deceleration motor 9 is transmitted to the inlaid rotating disk 74 and the power transmission block 73 through the synchronous belt pulley 12 and the synchronous conveyor belt 13, so that the electrostatic adsorption roller 11 rotates to wind and collect the self-sealing bag film. When winding and collecting, the electrostatic adsorption roller 11 becomes thicker, so that the induction adjustment rod 100 is extruded outward, and then the arc-shaped blocking block 105 disengages from the position of the limit sliding groove 75. Then, under the action of gravity, the electrostatic adsorption roller 11 slides downwards, and the induction adjustment rod 100 has no extrusion force and quickly resets under the action of the spring telescopic rod 104. The electrostatic adsorption roller 11 falling from the upper position is intercepted by the arc-shaped blocking block 105, the self-sealing bag film at the position of the falling electrostatic adsorption roller 11 is cut off and fixed with tape, and the end of the self-sealing bag film is placed on the surface of a new electrostatic adsorption roller 11 and continues to be wound. The staff pulls the intercepting door 4, and the forklift can fork away the electrostatic adsorption roller 11 after winding.

[0049] By loosening and tightening the wing bolt 101, the induction adjusting rod 100 can slide at the position of the adjusting slide plate 103. The distance from the inner side of the induction adjusting rod 100 to the outer side of the electrostatic adsorption roller 11 is the actual winding amount of the self-sealing bag film. After adjusting to the appropriate distance, tighten the wing bolt 101.

[0050] After the forklift forks away the electrostatic adsorption roller 11, the power adjusting block 112 can be pressed inward so that the power adjusting block 112 disengages from the sliding fixing groove 114, and then the plug 117 and the side protection plate 111 can be removed, which is convenient for removing the wound self-sealing bag film and also convenient for supplying power to the electrostatic roller main body 113.

[0051] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
