Description

Technical Field

[0001] The present invention relates to the technical field of plastic preparation, and particularly relates to a preparation process of PET steel belts. Background Art

[0002] PET steel belts, also known as PET steel packaging bags, are a new type of environmentally friendly packaging material used to replace steel belts. They have advantages such as high strength, high toughness, safety, adaptability, environmental friendliness, aesthetics, heat resistance, and economy. They are now widely used in industries such as the steel industry, chemical fiber industry, paper industry, screw industry, tobacco industry, electronics industry, textile industry, and wood industry.

[0003] In the preparation of existing PET steel belts, most of the winding of PET is carried out using winding equipment. However, after a roll of steel belt is wound by the traditional winding equipment, the staff needs to remove the wound winding turntable, then remove the wound steel belt roll, and then reinstall the winding turntable to its original position to enable the winding turntable to continue working. Most of the existing winding turntables are composed of a fixed disk and fixed bolts. When disassembling, the staff needs to first unscrew the bolts, then remove the fixed disk, and then the wound PET steel belt roll can be removed. The process is cumbersome and time-consuming. During this process, the preparation process of the PET steel belt does not stop. Therefore, a large amount of PET steel belts that have not been wound in time will accumulate in the middle of the winding equipment and the PET steel belt preparation equipment. A large amount of PET steel belts are piled up on the ground, which may cause the distortion and bending of the steel belts, making the PET steel belts not meet the factory standards, resulting in waste of PET steel belts. The PET steel belts piled up on the ground may also trip the working staff, posing a certain safety hazard. It also takes a lot of time to sort out the PET steel belts piled up on the ground. Existing PET steel belt winding equipment also needs to use paper rolls for shaping during winding, which increases the production cost of each roll of PET steel belt. Therefore, this application provides a preparation process of PET steel belts to meet the requirements. Summary of the Invention

[0048] As Figures 1-8 shown, an embodiment of the present invention provides a preparation process for PET steel belt, including material preparation, extrusion, first cooling, first traction and stretching, first heating, second traction and stretching, second heating, third traction and stretching, embossing, third heating, second cooling, and winding;

[0049] Material preparation is to crush and heat the PET steel belt raw material through a crusher and a heating barrel;

[0050] Extrusion is to extrude and initially form the heated material through an extrusion machine;

[0051] The first cooling is to cool the extruded and formed material through a water tank;

[0053] The first heating is to heat the belt blank after the first cooling treatment through an oven;

[0058] The third heating is to heat-treat the strip blank after embossing through an oven to obtain a plastic-steel belt;

[0059] The second cooling is to cool the plastic-steel belt after embossing through a water tank and then remove water using a sponge to obtain the finished plastic-steel belt;

[0060] Rewinding is to wind up the finished plastic-steel belt through a rewinding machine.

[0061] In this embodiment, as Figures 1 to 8 shown, a first motor group 2 is fixedly connected to the upper end of the rewinding equipment body 1. The output shaft at one end of the first motor group 2 is fixedly connected to a first lead screw 3. A connecting sleeve 4 is movably connected to the outer wall of the first lead screw 3. A first limiting block 5 fixedly connected to the outer wall of the connecting sleeve 4 is adapted to a limiting groove 6 opened at the upper end of the rewinding equipment body 1. One end of the connecting sleeve 4 is fixedly connected to a limiting shaft 7. The lower end of the limiting shaft 7 is fixedly connected to a limiting plate 33. A connecting spring 34 is fixedly connected to one side of the limiting plate 33. A rotating shaft 35 is movably connected to the middle of the limiting shaft 7. The lower end of the limiting shaft 7 is rotatably connected to a first guiding plate 8. The lower end of the first guiding plate 8 is fixedly connected to a cylinder group 9. The lower end of the cylinder group 9 is fixedly connected to a second guiding plate 10. The sides of the second guiding plate 10 and the first guiding plate 8 are both "U"-shaped. Anti-slip strips are fixedly connected to the upper end of the second guiding plate 10.

[0062] The first motor set 2 is connected to the connecting sleeve 4 through the first lead screw 3, and is fixedly connected to the limit shaft 7 and the first limit block 5 through the connecting sleeve 4, so that the first limit block 5 can limit the moving direction of the connecting sleeve 4, that is, limit the moving position of the limit shaft 7, so that the first motor set 2 can drive the first lead screw 3 to rotate to make the connecting sleeve 4 drive the limit shaft 7 to move back and forth. Since the sides of the second guide plate 10 and the first guide plate 8 are both "U"-shaped, the second guide plate 10 and the first guide plate 8 can limit the moving direction of the plastic steel belt. Through the anti-slip strips at the upper end of the second guide plate 10, the friction between the second guide plate 10 and the plastic steel belt is increased, so that the second guide plate 10 can drive the plastic steel belt to move, so that the limit shaft 7 can guide the plastic steel belt to wind around the outer wall of the winding wheel 11 together with the first guide plate 8 and the second guide plate 10. The plastic steel belt wound around the outer wall of the winding wheel 11 is uniform and flat, so that the effect after the plastic steel belt is wound is better.

[0063] Through the cylinder group 9 connected to the middle of the first guide plate 8 and the second guide plate 10, the cylinder group 9 can limit the relative positions of the first guide plate 8 and the second guide plate 10. The cylinder group 9 can control the movement of the second guide plate 10, so that the second guide plate 10 cooperates with winding wheels 11 at different positions. Thus, when the device fixes the position of the plastic steel belt wound on the surface of one winding wheel 11, another winding wheel 11 can wind the plastic steel belt. The limit plate 33 at the lower end of the limit shaft 7 is fixedly connected to the first guide plate 8 through the connecting spring 34, so that the connecting spring 34 can help the first guide plate 8 to always rotate downward, so that the first guide plate 8 can drive the second guide plate 10 to fit with the winding wheel 11 through the cylinder group 9. The plastic steel belt guided by the second guide plate 10 can be smoothly wound around the outer wall of the winding wheel 11. Through the rotating shaft 35 movably connected to the middle of the limit shaft 7, when the plastic steel belt rotates, it can drive the rotating shaft 35 to rotate, reducing the friction when the plastic steel belt moves on the outer wall of the rotating shaft 35, making the winding of the device smoother. Thus, the pause time of the device when winding the plastic steel belt is shortened, reducing the length of the plastic steel belt that has not had time to be wound and piled up on the ground, reducing the twisting and bending of the plastic steel belt caused by the too long length of the plastic steel belt piled up on the ground, thus avoiding the waste of the plastic steel belt caused by the non-compliance of the plastic steel belt with the factory standards, and also reducing the time consumed for sorting a large amount of plastic steel belt on the ground.

[0064] A push block 12 is fixedly installed in the middle of the coiling device body 1. The push block 12 is adapted to the guiding groove 13 opened on the outer wall of the coiling wheel 11. One end of the coiling wheel 11 is fixedly connected with a second motor group 14. The lower end of the second motor group 14 is fixedly connected with a moving wheel 31. A moving groove is opened in the middle of the coiling device body 1. The coiling wheel 11 is adapted to the moving groove in the middle of the coiling device body 1. The moving wheel 31 is located in the inner cavity of the moving groove in the middle of the coiling device body 1. A rack 15 fixedly connected to the outer wall of the second motor group 14 meshes with a circular gear 16. One end of the circular gear 16 is fixedly connected with a third motor group 17. A conveying group 32 is fixedly connected to the lower end of the coiling device body 1. A rubber pad is fixedly connected to the bottom of the conveying group 32. By the adaptation of the push block 12 and the guiding groove 13, the guiding groove 13 can move along the push block 12. Also, due to the adaptation of the coiling wheel 11 and the moving groove in the middle of the coiling device body 1, and the push block 12 being in contact with the inner wall of the middle groove of the coiling device body 1, when the coiling wheel 11 moves into the middle groove of the coiling device body 1, the push block 12 can help the coiling device body 1 to push the plastic steel belt wound around the outer wall of the coiling wheel 11 to fall to the bottom of the conveying group 32, avoiding the situation that the connection position of part of the plastic steel belt and the coiling wheel 11 is too tight, and preventing the plastic steel belt roll from spreading during the process of being pushed by the coiling device body 1, thereby improving the success rate of the device in automatically coiling the plastic steel roll. The rubber pad at the bottom of the conveying group 32 can reduce the impact of the plastic steel belt roll on the conveying group 32, avoid damage to the conveying group 32, and also prevent the plastic belt roll from spreading under the impact.

[0065] In this embodiment, as Figures 2-8As shown, one end of the first motor group 2 is fixedly connected to a belt group 18. One end of the belt group 18 is movably connected to a bevel gear group 19. One end of the bevel gear group 19 is fixedly connected to a second lead screw 20. The middle of the second lead screw 20 is movably connected to a moving block 21. The front end of the moving block 21 is movably connected to a first rotating gear group 22. The first rotating gear group 22 is composed of a gear, a connecting plate and a fixed shaft. The lower end of the first rotating gear group 22 is movably connected to a nut 30. The middle of the first rotating gear group 22 is fixedly connected to a tape tube 23. One end of the tape tube 23 is fitted with a second limit block 28. One end of the tape tube 23 is movably connected to a bolt 29. The bolt 29 is adapted to the second limit block 28. The lower end of the first rotating gear group 22 is movably connected to a roller 24. The outer wall of the roller 24 is in contact with the outer wall of the winding wheel 11. The second lead screw 20 is movably connected to the winding equipment body 1. The middle of the tape tube 23 is movably connected to a tape roll 36. The inner wall of the tape wound around the outer wall of the tape roll 36 is in contact with the winding wheel 11. The outer wall of the tape wound around the outer wall of the tape roll 36 is in contact with the roller 24. One end of the moving block 21 is fixedly connected to a pushing cylinder 25. The pushing cylinder 25 is rotationally connected to the first rotating gear group 22 through a transmission rod group 37. One end of the moving block 21 is rotationally connected to a second rotating gear group 26. The lower end of the second rotating gear group 26 is fixedly connected to a cutting group 27. The side of the cutting group 27 is triangular. The cutting group 27 is composed of a connecting rod at the upper end and a cutting blade at the lower end.

[0066] After a steel-plastic belt is wound around the outer wall of the winding wheel 11, start the first motor group 2 to drive the belt group 18 to rotate, then the belt group 18 drives the bevel gear group 19 to rotate, and then the bevel gear group 19 drives the second lead screw 20 to rotate, so that the second lead screw 20 can drive the moving block 21 to move to the required position of the corresponding winding wheel 11. Then start the pushing cylinder 25, so that the pushing cylinder 25 drives one end of the transmission rod group 37 to move downward to the lower end of the pushing cylinder 25, so that the other end of the transmission rod group 37 drives the first rotating gear group 22 to rotate downward. The first rotating gear group 22 drives the tape tube 23 and the roller 24 to move, and will also drive the second rotating gear group 26 to rotate upward, so that the roller 24 is in contact with the winding wheel 11.

[0067] The adhesive surface of the tape roll 36 is in contact with the plastic-steel tape wound around the outer wall of the winding wheel 11 for a period of time. The tape roll 36 fixes the position of the first circle of the plastic-steel tape after winding, preventing the plastic-steel tape roll from spreading after being separated from the winding wheel 11. It can also reduce the large increase in cost caused by using a paper roll for positioning in the inner cavity of the traditional plastic-steel tape roll, that is, reduce the production cost of the smaller plastic-steel tape roll. Then, operate the pushing cylinder 25 to drive one end of the transmission rod group 37 to move upward to the upper end of the pushing cylinder 25, so that the other end of the transmission rod group 37 drives the first rotating gear group 22 to rotate upward. The first rotating gear group 22 drives the tape tube 23 and the roller 24 to move upward, so that the roller 24 is no longer in contact with the winding wheel 11. When the first rotating gear group 22 rotates upward, the first rotating gear group 22 drives the second rotating gear group 26 to rotate downward, and the cutting group 27 and the roller 24 generate relative movement, so that the cutting group 27 cuts the adhesion between the tape roll 36 and the winding wheel 11, preventing the tape roll 36 from affecting the winding of the plastic-steel tape on the winding wheel 11. It can also enable the tape roll 36 to cooperate with another winding wheel 11 to work, improving the utilization rate of the equipment structure.

[0068] After the plastic-steel belt winding is completed, the above steps can be repeated to fix the position of the plastic-steel belt roll here. Then, the third motor group 17 can be started to drive the circular gear 16 to rotate, so that the circular gear 16 drives the rack 15, the second motor group 14 and the winding wheel 11 on one side to move backward. The plastic-steel belt roll on the outer wall of the winding wheel 11 falls into the inner cavity of the conveying group 32 under the push of the winding equipment body 1 and the pushing block 12. After that, the staff can collect the plastic-steel belt roll in the inner cavity of the conveying group 32, reducing the workload of the staff in wrapping the plastic-steel belt roll after removing the winding shaft, improving the overall working efficiency of the plastic-steel belt winding. When the rack 15 on one side of the circular gear 16 moves backward, the rack 15 on the other side of the circular gear 16 drives another second motor group 14 and the winding wheel 11 to move forward. At this time, the control air cylinder group 9 drives the second guide plate 10 to move to fit with another winding wheel 11, and then the winding of the plastic-steel belt can continue, reducing the influence of some steps after the winding is completed on the winding efficiency of the plastic-steel belt, and preventing the situation of a large amount of plastic-steel belt piling up on the ground, that is, avoiding the damage caused by the plastic-steel belt piling up on the ground and the situation of tripping the staff. The resistance during the movement of the second motor group 14 is reduced by the moving wheels 31 at the bottom of the second motor group 14. Since the side of the cutting group 27 is triangular, the cutting group 27 can stably move to cut the tape roll 36. The bolt 29 is adapted to the tape tube 23 and the second limit block 28, so that after the tape roll 36 in the middle of the tape tube 23 is used up, the bolt 29 can be disconnected from the tape tube 23 and the second limit block 28, and then the second limit block 28 is disconnected from the tape tube 23. After that, the used tape roll 36 is removed and a new tape roll 36 is replaced, making the replacement steps of the tape roll 36 simple and having a good fixing effect on the position of the tape roll 36, avoiding the disconnection of the tape roll 36 from the tape tube 23 during the operation of the equipment, so that the use effect of the device is better. Since the roller 24 is movably connected to the tape tube 23, the roller 24 can help the tape roll 36 to be smoothly pasted on the winding wheel 11, fix the position of the plastic-steel belt roll, and make the device work smoothly.

[0069] The technical solution provided by the present invention is that the first motor group drives the first lead screw to rotate, so that the connecting sleeve drives the limiting shaft to move back and forth. The relative positions of the first guide plate and the second guide plate can be limited by the air cylinder group, so that the air cylinder group can control the movement of the second guide plate. The second guide plate cooperates with winding wheels at different positions, so that when the equipment fixes the position of the plastic-steel belt wound on the surface of one winding wheel, another winding wheel can wind the plastic-steel belt, thus shortening the pause time when the equipment winds the plastic-steel belt, reducing the length of the plastic-steel belt that has not been wound in time and piled up on the ground, and reducing the twisting and bending of the plastic-steel belt caused by the too long length of the plastic-steel belt piled up on the ground, resulting in the plastic-steel belt not meeting the factory standards. A large amount of plastic-steel belt piling up may also trip the staff, posing a certain safety hazard and causing waste of the plastic-steel belt. It can also reduce the time consumed in sorting out a large amount of plastic-steel belt on the ground.

[0070] When moving into the middle groove of the winding device body through the winding wheel, the push block can help the winding device body push the plastic-steel belt wound around the outer wall of the winding wheel to fall to the bottom of the conveying group, avoiding the situation that the connection position between some plastic-steel belts and the winding wheel is too tight, so that the plastic-steel belt roll spreads during the process of being pushed by the winding device body, thereby improving the success rate of the device to automatically wind the plastic-steel roll. The rubber pad at the bottom of the conveying group can reduce the impact of the plastic-steel belt roll on the conveying group, avoid damage to the conveying group, and also avoid the plastic-steel belt roll from spreading under the impact.

[0071] The other end of the transmission rod group drives the first rotating gear group to rotate downward, so that the first rotating gear group drives the tape tube and the roller to move, and also drives the second rotating gear group to rotate upward, so that the roller fits with the winding wheel, and the adhesive surface of the tape roll fits with the plastic-steel belt wound around the outer wall of the winding wheel for a period of time. The tape roll fixes the position after the first circle of the plastic-steel belt is wound, avoiding the plastic-steel belt roll from spreading after being separated from the winding wheel, and also reducing the large increase in cost caused by using a paper roll to shape the inner cavity of the traditional plastic-steel belt roll, that is, reducing the production cost of the plastic-steel belt roll.
