Description

Technical Field

[0001] The invention relates to the technical field of plastic bag production, in particular to process-intensive plastic bag production equipment. Background Art

[0002] Plastic bags are convenient, cheap, and widely used. Plastic bags are made by hot-melting polyethylene powder and then blowing and pressing it, which requires a plastic bag forming device. The traditional plastic bag production process is to obtain molten plastic material through an extruder, then form a tubular film through a plastic film blowing machine, and finally form it through extrusion and folding.

[0003] However, when the plastic film blowing machine blows to form a tubular film, it is usually directly combined with the air blowing module to inflate the molten plastic material, first heat it, then extrude it through a cylindrical tube, and inject high-pressure air into it to blow it into a cylinder. Finally, the cylindrical plastic bag moves upward through a roller and cools down during the movement. After blow molding, it needs to be naturally cooled and shaped in the air. When the plastic bag was first produced, the existing equipment manually pulled the head of the plastic bag film and hung the plastic bag head film on the roller. There were multiple rollers, and the plastic bag head film was transmitted linearly between the multiple rollers. The roller at the end of the equipment can be disassembled and can also wrap the plastic bag film. At the same time, the roller at the end also plays a pulling role on the plastic bag film.

[0004] However, when plastic bags were first produced, the manual positioning of the bags was poor, and they needed to be smoothed and wrapped manually. After the rollers at the end were fully wrapped with the plastic bag film, they were still removed manually. The plastic bag film lost the force generated by the pulling, which would cause the film and the rollers to slip. There was still gas inside the tubular film, and the tubular film would continue to expand and deform the plastic bag. To prevent this problem, the existing operating methods can be the following two: First, immediately stop rotating the multiple rollers and stop blowing the plastic material, but this is only suitable for the case where the tubular film cools down faster, depending on the thickness of the produced plastic bag. Once the tubular film cools down for a while, the film will stop blowing. The first method is to use a roller at the end of the equipment to assist in pulling the plastic bag film. However, the pulling force is unstable during the manual pulling of the plastic bag film, which may cause a part of the plastic bag film to deform. In addition, the end of the plastic bag film needs to be manually pulled manually, which increases the difficulty of operation and easily affects quality control. Therefore, we propose a process-intensive plastic bag production equipment. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] After the blade contacts the pressing rod, the blade moves toward the outer ring of the winding roller and compresses the second spring. Then, the side edge of the blade is heated and contacts the back of the plastic bag film to dry the glue between the winding roller and the plastic bag film. Then, the rotating seat is quickly reset at the first time to prevent the blade from being stuck at the bottom of the plastic bag film and unable to move out. Finally, after the winding roller and the two rotating seats are separated, the blade rolls along the triangular seat onto the support bar to rotate the plastic bag film in the production process.

[0018] The electrical signal is transmitted to the second cylinder. During the extension of the movable rod of the second cylinder, the glue extruding rod is brought into contact with one side of the rotating seat through the movement of the baffle to extrude the glue. At the same time, the baffle drives the bearing to move toward the shaft portion on one side of the rotating seat. The outer ring of the bearing pushes multiple first magnets and multiple second magnets to contact each other. The second magnet and the first magnet are opposite-sex magnets that attract each other, so that the rotating seat can be driven to rotate during the rotation of the first roller. Each second magnet is misaligned with each first magnet, and the rotation angle of the rotating seat is limited. At the same time, the first roller can also ensure that the original speed remains unchanged. After the winding roller and the rotating seat are separated, the second cylinder retracts in a very short time, and the second magnet and the first magnet are separated, as shown in the attached figure, so that the rotating seat is convenient to reset, so that the various structures are closely matched and the various equipment in the process production are closely connected.

Each of the switches 802 is located at both ends of the limiting tube 11, and both ends of the limiting tube 11 are threadedly connected with a thread lock 13. Both ends of the laminating roller 12 are fixedly installed with a moving rod 14, and one end of each of the moving rods 14 is rotatably connected with a support bar 15. A limiting bar 16 is fixedly installed on one side of each of the triangular seats 10, and the support bar 15 and the limiting bar 16 are slidably connected;The winding roller 9 is made of non-slip material, and the blade 19 is in a triangular shape, wherein the edges and corners of the blade 19 are sharp, and the side of the blade 19 will not cut the plastic bag film, wherein the blade 19 is electrically connected to the triangular seat 10, and when the triangular seat 10 is powered on and heated, the metal blade 19 generates heat at the same time, heats and solidifies the glue, and improves the ability of the winding roller 9 to roll the plastic bag, and prevents the winding roller 9 from having an unreliable contact with the plastic bag, so that the winding roller 9 cannot roll up the plastic bag. During production, the feeding cylinder 601 adds plastic raw materials, and the plastic raw materials are heated and melted by the heating device 6, and then the molten plastic raw materials are blown up by the air supply device 5 to form a hollow tube column. After the hollow tube column forms the plastic bag film, it passes over the frame 1 and passes through the inside of the winding table 2 again, and then is wound on the winding roller 9, wherein the initial position of the winding roller 9 is located above the support bar 15 and the winding roller 9 and the extension end are in conflict, and the rotation direction of the winding roller 9 is attached; Figure 4 When the winding roller 9 starts to rotate, the plastic bag film is wound;

[0032] As the number of plastic bag layers on the outer ring of the winding roller 9 increases, the accumulated thickness of the plastic bags can drive the laminating roller 12 to move on the arc guide rail 801. When the end of the laminating roller 12 contacts the switch 802, the switch 802 sends a signal to the computer console, which then sends information to the winding table 2, causing one of the rotating seats 18 to rotate, and the other rotating seat 18 connected by the blade 19 also rotates. The winding roller 9 with the unwound plastic bag film on the outer ring is carried between the two rotating seats 18, and the two rotating seats 18 rotate simultaneously. When the plastic bag film is wound around the winding roller 9 above the support bar 15, the blade 19 first cuts the plastic bag film wound around the winding roller 9 above the support bar 15, and one end of the cut plastic bag film is placed on the winding roller 9 of the unwound plastic bag film. At the same time, the support bar 15 and the limit bar 16 are separated, and the winding roller 9 that has been wound around the plastic bag film falls between the extended end of the rotating frame 8 and the triangular seat 10 due to its own weight. The pressing roller 12 is reset without the support, and the support bar 15 and the limit bar 16 start to contact again. During this process, the two rotating seats 18 rotate. Afterwards, the winding roller 9 carried by the rotating seat 18 is placed on the triangular seat 10. At the same time, during the rotation of the two rotating seats 18, the drainage rod 20 is used to discharge glue and is located at the top of the two rotating seats 18, so that the glue is dripped onto the winding roller 9. Due to its own weight, when the rotating seat 18 rotates, the drainage rod 20 descends on the rotating seat 18 and contacts the plastic bag film, pressing the plastic bag film onto the winding roller 9. Then, after the blade 19 contacts the pressing rod 17, the blade 19 moves toward the outer ring of the winding roller 9 and compresses the second spring 1801, and then the blade 19 is pressed against the side of the winding roller 9. After being heated, the edge comes into contact with the back of the plastic bag film to dry the glue between the winding roller 9 and the plastic bag film, and then the rotating seat 18 is quickly reset at the first time to prevent the blade 19 from being trapped at the bottom of the plastic bag film and unable to move out. Finally, after the winding roller 9 and the two rotating seats 18 are separated, they roll along the triangular seat 10 to the support bar 15 to rotate the plastic bag film in the production process. During this process, there is no need to stop the machine for operation and no manual assistance, which improves the product production efficiency while improving quality control and ensuring the yield of the finished product.

[0033] Furthermore, a heating section 1001 is provided on the top of the two triangular seats 10, and the extending end of the arc guide rail 801 has an opening direction toward the placement area of ​​the triangular seat 10 for placing the winding roller 9. One end of the heating section 1001 extends toward the placement area and forms a downward slope. The heating section 1001 provides heat to the plastic bag film at both ends of the winding roller 9 when the winding roller 9 rolls, thereby improving the curing effect of the glue and preventing the plastic bag film from being demolded when the winding roller 9 rolls.

[0034] Furthermore, a second roller 29 is rotatably connected to the bottom of the winding platform 2, and a first roller 27 is rotatably connected to the top of the winding platform 2. Each of the rotating seats 18 is located at the end of the first roller 27, and a plurality of second magnets 28 are annularly installed at one end of the first roller 27. A fixing ring 23 is fixedly installed on the outside of the winding platform 2 near the end of the first roller 27, and a second cylinder 25 is suspended on one side of the fixing ring 23. A baffle 24 is fixedly installed on the movable rod of the second cylinder 25, and a bearing 22 is fixedly connected to one side of the baffle 24. A plurality of first magnets 21 are annularly installed on the outer ring of the bearing 22. The plurality of first magnets 21 penetrate the rotating seat 18 and the second magnet 28 are attracted together. A glue squeezing rod 26 is fixedly installed on the outer ring of the baffle 24, and the glue squeezing rod 26 and one side of the rotating seat 18 conflict with each other. When the two ends of the pressing roller 12 are in contact with the switch 802, The electrical signal is transmitted to the second cylinder 25. During the extension of the movable rod of the second cylinder 25, the glue extruding rod 26 is brought into contact with one side of the rotating seat 18 through the movement of the baffle plate 24 to squeeze out the glue. At the same time, the baffle plate 24 drives the bearing 22 to move toward the shaft portion of one side of the rotating seat 18. The outer ring of the bearing 22 pushes the plurality of first magnets 21 and the plurality of second magnets 28 to contact each other. The second magnets 28 and the first magnets 21 are magnets of opposite poles that attract each other, so that the rotating seat 18 can be driven to rotate during the rotation of the first rotating roller 27. That is, after the two ends of the winding roller 9 contact the triangular seat 10, each second magnet 28 and each first magnet 21 are misaligned, and the rotation angle of the rotating seat 18 is limited. At the same time, the first rotating roller 27 can also ensure that the original rotation speed remains unchanged. After the winding roller 9 and the rotating seat 18 are separated, the second cylinder 25 retracts in a very short time, and the second magnet 28 and the first magnet 21 are separated. As shown in the attached figure Fig. 9 As shown, the rotating seat 18 is also controlled by a spring (as shown in the attached Fig. 9 As shown), it is convenient for the rotating seat 18 to be reset, so that each structure is closely matched and each device in the process production is closely connected;

[0035] Specifically, after the plastic bag film between the first roller 27 and the winding roller 9 is cut by the blade 19, since the device is still in operation, the plastic bag film above the first roller 27 continues to move forward due to the rotation of the first roller 27, so that after the winding roller 9 passes over the back of the plastic bag film, the front of the moving plastic bag film covers the outer circle of the winding roller 9, and then the blade 19 gradually contacts the pressing rod 17, and the blade 19 compacts the plastic bag film and the winding roller 9.

[0036] Furthermore, stabilizing blocks are fixedly installed at both ends of the winding roller 9, a solid end 904 is installed at the bottom of each stabilizing block, and a virtual end 901 is arranged on the top of the stabilizing block. A limiting plate 903 is fixedly installed on each of the winding rollers 9, and a first gear 902 is fixedly installed between the stabilizing block and the limiting plate 903. Each of the first gears 902 is fixedly connected to the winding roller 9. The limiting plate 903 prevents the winding roller 9 from deflecting when the material is dropped. At the same time, the solid end 904 can quickly put the winding roller 9 to a standstill after the material is dropped, thereby improving the stability of the device during operation and reducing failures.

[0037] Furthermore, one end of the first roller 27 is connected to a second pulley 34 in a transmission manner, and the second pulley 34 is rotatably connected to a driving gear 33 at an end away from the first roller 27. A transition gear 32 is rotatably installed on the outside of the winding platform 2, and the transition gear 32 is connected to the first pulley 31 in a transmission manner. One end of the first pulley 31 is connected to a second gear 30 in a transmission manner. The second gear 30 is located at the bottom of the limit strip 16. The second gear 30 is rotatably connected to the winding platform 2, and the second gear 30 is meshed with the first gear 902 for transmission. When the first roller 27 rotates, During the process, the shaft of the first roller 27 drives the second pulley 34 to rotate, the rotation of the second pulley 34 drives the driving gear 33 to rotate clockwise, the rotation of the driving gear 33 drives the transition gear 32 to rotate counterclockwise, the rotation of the transition gear 32 drives the first pulley 31 to rotate, the rotation of the first pulley 31 drives the second gear 30 to rotate, the rotation of the second gear 30 drives the first gear 902 to engage and transmit, when the outer ring of the winding roller 9 is full of plastic bag film, the winding roller 9 can fall from between the triangular seat 10 and the rotating frame 8 along the extended end, so that the winding roller 9 has a detachable function.

[0038] Furthermore, an inclined platform 3 is fixedly installed on one side of the bottom of the winding table 2, and a feeding roller is rotatably connected to the top between the two rotating racks 8. A guide plate is installed at the other end of each rotating rack 8. The winding roller 9 can contact the inclined platform 3 during the process of falling from between the triangular seat 10 and the rotating rack 8 along the extended end, which has a certain buffering effect and reduces the breakage rate of the plastic bag film.

[0039] Furthermore, a lifting guide rail 101 is installed on the side of the frame 1 away from the winding table 2, and a motor 4 is slidably connected to the lifting guide rail 101. The output shaft of the motor 4 is installed with a roller that rolls on the lifting guide rail 101, and a first cylinder 401 is installed on one side of the motor 4. An air leveling pipe 402 is fixedly installed on the movable rod of the first cylinder 401, and a top mixing roller 7 is fixedly installed on the top of the frame 1. When production starts, the motor 4 can be turned on to drive the roller to rise on the lifting guide rail 101. After the tubular plastic film is extended through the movable rod of the first cylinder 401, the air leveling pipe 402 contacts the plastic film and is kneaded into a strip at the top mixing roller 7. The tubular plastic film is dried by air cooling and does not require manual assistance to pull, thereby improving the degree of automation of the device.
