Description

Technical Field

[0001] This invention relates to the field of yarn covering and bagging technology, specifically to an automatic yarn covering and bagging mechanism based on yarn cones. Background Technology

[0002] The automatic yarn wrapping and bagging device mainly consists of core components such as film traction, film guide plate, yarn package transport, and sealing. Its working principle is as follows: a roll of film is set on one side of the machine body and inside the machine body. Then, the film located outside the machine is pulled to the film guide plate by the traction mechanism. The film guide plate changes the winding and transport path of the film so that it is aligned with the direction of the conveyor belt. Then, the film traction mechanism inside the machine pulls out the film inside the machine so that the two films are in contact on one side. Then, the hot air cutter on the equipment seals the contact point of the two films. At this time, the two films are connected as one. Then, the yarn package is transported between the two films. Then, the hot air cutter heat-seals the remaining three sides of the two films again to complete the yarn package bagging work. At the same time, the heat-sealing cutter cuts off the heat-sealed packaging bag so that the next yarn package bagging work can be carried out. During the use of the guide plate, friction occurs between the film and the guide plate, which can cause wear marks such as grooves on the top surface of the guide plate. This increases friction on the film during subsequent bagging, and in severe cases, can tear the film. If the batch of yarn is being bagged urgently or a new guide plate is not immediately available, temporary repairs to the grooves are necessary. Currently, temporary repairs typically involve using specialized tape to cover the grooves, thus temporarily repairing the guide plate and allowing it to continue bagging the batch of yarn. Once the bagging of the batch of yarn is complete, the guide plate is replaced.

[0003] Existing methods for temporarily repairing grooves with tape typically involve manual repair. However, grooves caused by film friction on the forming device are often narrow and shallow. This makes it easy to misjudge the size of the groove during manual repair, resulting in the tape not completely covering it. A significant difference in thickness between the uncovered groove and the tape exacerbates damage to the film. To address this, we propose an automatic yarn wrapping and bagging mechanism based on yarn packages. Summary of the Invention

[0008] Preferably, a plurality of springs are fixedly connected between the inner top wall of the mounting groove and the top of the movable main cutter.

[0010] Preferably, the guide roller is located between the take-up roller and the unwind roller, and the height of the guide roller is lower than the bottom opening edge of the mounting cover.

[0011] Preferably, two drive wheels are rotatably connected to one side of the mounting cover, and the two drive wheels are fixedly connected to one end of the unwinding roller and the winding roller, respectively, and a belt is provided between the two drive wheels.

[0012] Preferably, a support frame is fixedly connected to the side of the machine body near the conveyor belt A. A film winding roller and a film guiding roller are rotatably connected to the support frame, with the film guiding roller located above the film winding roller. Two leveling rollers aligned vertically are rotatably connected to the support frame. Two meshing gears are rotatably connected to one side of the support frame, with each gear fixedly connected to one end of a leveling roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention sets several evenly distributed dividing strips on the guide plate to divide the guide plate into multiple areas. When the guide plate is illuminated by a light, a shadow with the same length as the groove scratch will appear at the groove scratch on the guide plate. The dividing strips determine the position and length of the shadow on the guide plate, which facilitates the positioning of the groove scratch and avoids the problem of misjudging the size of the groove, resulting in the tape not completely covering the groove. This effectively improves the auxiliary function of the device for temporary repair of scratches on the guide plate. 2. When using special tape to temporarily repair scratches on the guide plate, the present invention uses a fixed main cutter to cut the starting end of the special tape. After cutting, the moving main cutter continuously cuts both sides of the special tape. While ensuring that the special tape is not broken, only the middle part of the special tape is used for temporary repair of scratches on the guide plate. This avoids the special tape breaking, which would prevent the special tape on the unwinding roller from continuing to cooperate with the winding roller for stable winding and unwinding. This optimizes the continuity of the device when temporarily repairing scratches on the guide plate. 3. When using special tape to temporarily repair scratches on the guide plate, the present invention uses a fixed main cutter with an arc-shaped structure to cut the starting end of the special tape into an arc shape. This reduces the friction between the special tape and the film as the film passes through the tape, avoiding the problem of the right-angled edge of the special tape easily scratching the film. At the same time, when using special tape to repair scratches on the guide plate, the guide roller can flatten the special tape, allowing it to better adhere to the guide plate. This avoids the problem of air bubbles forming inside the special tape due to air between the tape and the guide plate, thus optimizing the smoothness of the film passing through the special tape.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-8 This invention provides a technical solution: an automatic yarn wrapping and bagging mechanism based on yarn packages, comprising a machine body 1, on which conveyor belts A11 and B12 are respectively mounted, and a heat-sealing cutter 13 is provided on conveyor belt B12. A fixed frame 2 is fixedly connected to the machine body 1, and a triangular guide plate 21 is fixedly connected to the side of the fixed frame 2 near the conveyor belt A11. A load-bearing frame 9 is fixedly connected to the side of the machine body 1 near the conveyor belt A11, and a film-winding roller 91 and a guide roller 92 are rotatably connected to the load-bearing frame 9, with the guide roller 92 located above the film-winding roller 91. Two vertically aligned leveling rollers 93 are rotatably connected to the load-bearing frame 9, and two meshing gears 94 are rotatably connected to one side of the load-bearing frame 9. The two gears 94 are fixedly connected to one end of the two leveling rollers 93 respectively. A motor 95 is fixedly connected to the side of the load-bearing frame 9 away from the gears 94, and the output end of the motor 95 is fixedly connected to one of the leveling rollers 93.

[0020] Furthermore, the machine body 1 is also equipped with a film traction mechanism that moves in the same direction as the conveyor belt A11. This film traction mechanism transports the film from bottom to top, conveying it through the gap between conveyor belts A11 and B12 to below the heat-sealing cutter 13. Simultaneously, the motor 95 starts, cooperating with two gears 94 to drive two leveling rollers 93 to rotate together. The leveling rollers 93 transport the film on the film roll 91 to the guide plate 21, and the inclined side of the guide plate 21 changes the direction of film movement, aligning it with the transport direction of the conveyor belt A11. One end of the film is then transported to below the heat-sealing cutter 13 on the conveyor belt B12, where the ends of the two films are joined together. The heat-sealing cutter 13 then... The edges where the two films meet are heat-sealed. Then, the yarn bobbin is transported to the conveyor belt B12 using the conveyor belt A11. At this time, the yarn bobbin is located between the two films, and under the transport of the conveyor belt B12, the yarn bobbin moves one end of the film away. Then, the heat-sealing cutter 13 heat-seales the remaining three sides of the two films. After heat sealing, a film bag is formed, and the yarn bobbin is bagged. The cutting mechanism of the heat-sealing cutter 13 is used to cut the heat-sealed film bag, breaking it from the original film. Under the transport of the conveyor belt B12, the material is dropped. During the cutting process of the film bag, the heat-sealing cutter 13 cuts from the middle of the heat-sealed part of the film. At this time, the two films are still in a single-sided connection state, and the bagging work of the next yarn bobbin can continue.

[0021] Combined with appendix Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the top of the guide plate 21 is fitted with several evenly distributed dividing strips 22. A lighting lamp 3 is fixedly connected to the side of the fixing frame 2 near the conveyor belt A11. A vision sensor 31 is fixedly connected to the top of the fixing frame 2. A transverse slide rail 4 is fixedly connected to the fixing frame 2. A longitudinal slide rail 5 is slidably connected to the transverse slide rail 4. A transmission seat 6 is slidably connected to the bottom of the longitudinal slide rail 5. Several electric push rods 61 are fixedly connected to the bottom of the transmission seat 6. A mounting cover 62 is fixedly connected to the bottom of the electric push rods 61. The bottom of the mounting cover 62 has an opening. An unwinding roller 7 and a take-up roller 71 are rotatably connected to the bottom of the mounting cover 62. A guide roller 74 is rotatably connected to the bottom of the mounting cover 62. The guide roller 74 is located between the take-up roller 7 and the unwinding roller 71. The height of roller 74 is lower than the bottom opening edge of mounting cover 62. Industrial tape is wound between unwinding roller 7 and take-up roller 71. Two drive wheels 72 are rotatably connected to one side of mounting cover 62. The two drive wheels 72 are fixedly connected to one end of unwinding roller 7 and take-up roller 71 respectively. A belt 73 is provided between the two drive wheels 72. A screw A41 is rotatably connected inside transverse slide rail 4. A threaded connection is made between longitudinal slide rail 5 and screw A41. A motor A42 for driving screw A41 is fixedly connected to one end of transverse slide rail 4. A screw B51 is rotatably connected inside longitudinal slide rail 5. A threaded connection is made between drive seat 6 and screw B51. A motor B52 is fixedly connected to one end of longitudinal slide rail 5. The motor B52 is fixedly connected to one end of screw B51.

[0022] Furthermore, during the use of the device, the lighting lamp 3 is turned on to obliquely illuminate the top surface of the guide plate 21. When there are grooves or scratches on the surface of the guide plate 21, the illumination will leave a shadow on the surface of the guide plate 21. At this time, the vision sensor 31 detects the shadow and uses the various separators 22 to determine the length of the shadow. Then, the motor A42 is started to drive the screw A41 to rotate. The rotating screw A41 is used to adjust the lateral position of the mounting cover 62. The motor B52 is turned on to drive the screw B51 to rotate. The rotating screw B51 cooperates with the transmission seat 6 to adjust the longitudinal position of the mounting cover 62. When the mounting cover 62 is located at the groove or scratch of the guide plate 21... When directly above, the electric push rod 61 extends, causing the mounting cover 62 to descend, so that the guide roller 74 is in contact with the guide film plate 21. At this time, the special tape placed on the bottom of the guide roller 74 can adhere to the groove scratches on the guide film plate 21. Then, the motor A42 starts again, causing the mounting cover 62 to move laterally. During its movement, it can drive the guide roller 74 to rotate, thereby driving the special tape to move. During the movement of the special tape, it can pull the unwinding roller 7 to rotate. During the rotation of the unwinding roller 7, through the cooperation of the transmission wheel 72 and the belt 73, it drives the take-up roller 71 to rotate synchronously in the same direction, thereby completing the unwinding and take-up operations of the tape at the same time, until the special tape covers the groove scratches on the guide film plate 21.

[0023] Combined with appendix Figure 5 , Figure 6 and Figure 8 As shown, two electromagnetic slide rails 8 are fixedly connected to the inner walls of both sides of the mounting cover 62. A mounting plate 81 is slidably connected between the two electromagnetic slide rails 8 near the take-up roller 71. A telescopic rod 82 is fixedly connected to the bottom of the mounting plate 81. A fixing plate 83 is fixedly connected to the bottom of the telescopic rod 82. An arc-shaped fixing main cutter 85 is fixedly connected to the bottom of the fixing plate 83. Limiting posts 84 are fixedly connected to both sides of the top of the fixing plate 83. A gap is provided between the top of the limiting post 84 and the bottom of the mounting plate 81. Sleeve plates 86 are fixedly connected to both sides of the bottom of the fixing plate 83. Each of the 86 has a mounting groove 87 at its bottom. A movable main cutter 810 is slidably connected in the mounting groove 87. Several springs 88 are fixedly connected between the inner top wall of the mounting groove 87 and the top of the movable main cutter 810. Each spring 88 has a telescopic limit rod 89. The top and bottom of the telescopic limit rod 89 are fixedly connected to the inner top wall of the mounting groove 87 and the top of the movable main cutter 810, respectively. A secondary cutter 811 is slidably connected between the two electromagnetic slide rails 8 on the side near the unwinding roller 7. The length of the secondary cutter 811 is the same as the distance between the two movable main cutters 810.

[0024] Furthermore, the width of the special adhesive tape is greater than the distance between the two movable main cutters 810. When the tape adheres to the surface of the guide plate 21, the electromagnetic slide rail 8 near the take-up roller 71 drives the fixed main cutter 85 to descend and cut the tape. At this time, the arc-shaped fixed main cutter 85 can make one end of the tape facing the film movement direction form an arc shape, thereby reducing the friction between the film and the tape. During this process, the movable main cutter 810 descends together with the mounting plate 81 and positions and cuts the two sides of the special adhesive tape. After the fixed main cutter 85 finishes cutting, the electromagnetic slide rail 8 drives the mounting plate 81 to rise a certain distance. The fixed main cutter 85 is separated from the special tape. At this time, due to the rebound characteristic of the spring 88, the moving main cutter 810 will be pushed downward, so that the moving main cutter 810 continues to cut both sides of the tape. When the special tape completely covers the groove scratches on the surface of the guide plate 21, the secondary cutter 811 on the electromagnetic slide rail 8 near the unwinding roller 7 falls down and completely cuts the special tape. Then, the guide roller 74 is used to flatten the end of the special tape. At this time, the temporary repair work on the groove scratches on the surface of the guide plate 21 is completed, so that it can be used normally for a short time until the new guide plate 21 arrives and is replaced.

[0025] Working principle: First, the machine body 1 is installed in the designated working position. Inside the machine body 1, a film traction mechanism is installed in the same direction as the conveyor belt A11. This film traction mechanism transports the film from bottom to top, conveying it through the gap between conveyor belts A11 and B12 to below the heat-sealing cutter 13. Simultaneously, the motor 95 starts, cooperating with two gears 94 to drive two leveling rollers 93 to rotate together. The leveling rollers 93 transport the film from the film roll 91 to the guide plate 21, and the inclined side of the guide plate 21 changes the direction of film movement, aligning it with the transport direction of conveyor belt A11. One end of the film is then transported to below the heat-sealing cutter 13 on conveyor belt B12, at which point the ends of the two films are joined together. The heat-sealing cutter 13 is used to heat-seal the edges where the two films are in contact. Then, the yarn bobbin is transported to the conveyor belt B12 using the conveyor belt A11. At this time, the yarn bobbin is located between the two films, and under the transport of the conveyor belt B12, the yarn bobbin moves one end of the film away. Then, the heat-sealing cutter 13 is used to heat-seal the remaining three sides of the two films. After the heat-sealing is completed, a film bag is formed, and the yarn bobbin bagging is completed. The cutting mechanism of the heat-sealing cutter 13 is used to cut the heat-sealed film bag, so that it is disconnected from the original film. Under the transport of the conveyor belt B12, the material is dropped. During the cutting process of the film bag, the heat-sealing cutter 13 cuts from the middle of the heat-sealed part of the film. At this time, the two films are still in a single-sided connection state, and the bagging work of the next yarn bobbin can continue. During device use, the lighting 3 is turned on to continuously illuminate the top surface of the guide plate 21 at an angle. When there are grooves or scratches on the surface of the guide plate 21, the illumination will leave a shadow on the surface of the guide plate 21. At this time, the vision sensor 31 detects the shadow and uses the various separators 22 to determine the length of the shadow. Then, the motor A42 is started to drive the screw A41 to rotate. The rotating screw A41 is used to adjust the lateral position of the mounting cover 62. The motor B52 is turned on to drive the screw B51 to rotate. 1. In conjunction with the transmission seat 6, the longitudinal position of the mounting cover 62 is adjusted. When the mounting cover 62 is directly above the groove and scratch on the guide film plate 21, the electric push rod 61 extends, causing the mounting cover 62 to descend, so that the guide roller 74 is in contact with the guide film plate 21. At this time, the special adhesive tape at the bottom of the guide roller 74 can be attached to the groove and scratch on the guide film plate 21. When the tape is attached to the surface of the guide film plate 21, the electromagnetic slide rail 8 near the take-up roller 71 drives the fixed main cutter 85 to descend, cutting the tape. At this time, the arc-shaped fixed main cutter 85 can be used to make the direction towards One end of the tape in the film movement direction forms an arc shape to reduce friction between the film and the tape. During this process, the moving main cutter 810 descends along with the mounting plate 81, positioning and cutting both sides of the special tape. After the fixed main cutter 85 finishes cutting, the electromagnetic slide rail 8 drives the mounting plate 81 to rise a certain distance, separating the fixed main cutter 85 from the special tape. At this time, due to the rebound characteristic of the spring 88, the moving main cutter 810 is pushed downward, allowing it to continue cutting both sides of the tape. Then the motor... A42 restarts, causing the mounting cover 62 to move laterally. During this movement, the guide roller 74 rotates, which in turn moves the special tape. As the special tape moves, it pulls the unwinding roller 7, causing it to rotate. During the rotation of the unwinding roller 7, the transmission wheel 72 and belt 73 work together to drive the take-up roller 71 to rotate synchronously in the same direction, thus completing the unwinding and take-up operations of the tape simultaneously. During this process, the moving main cutter 810 continuously cuts both sides of the special tape until the special tape covers the grooves and scratches on the guide plate 21. After the special tape completely covers the grooves and scratches on the surface of the guide plate 21, the secondary cutter 811 on the electromagnetic slide rail 8 near the unwinding roller 7 falls down and completely cuts the special tape. Then, the guide roller 74 flattens the end of the special tape. At this time, the temporary repair work on the grooves and scratches on the surface of the guide plate 21 is completed, so that it can be used normally for a short time until the new guide plate 21 arrives and is replaced.
