[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention uses a lifting system composed of a driving motor, a reducer, a sprocket and a chain to dynamically adjust the horizontal position of the mobile platform according to the height of the equipment to be covered with film, and realize millimeter-level precision control. The reducer adopts a structure with a locking function such as a worm gear to ensure that the mobile platform is locked at any height, avoiding sliding caused by equipment vibration or film material tensile force, thereby ensuring the accuracy of the film covering position, which is particularly suitable for multi-layer stacking or product packaging with large height differences, reducing film material waste and packaging defects caused by positioning deviations.

[0017] 2. The present invention adopts a non-heating cold stretching process, which utilizes the elasticity of the film material itself to achieve film sleeve, avoiding the risk of thermal damage to temperature-sensitive products caused by traditional heat shrinkage processes, while eliminating the energy consumption cost and fire hazards caused by heating devices. The full-process automation design reduces manual contact and is especially suitable for scenes with high hygiene requirements such as medicine and food. During the packaging process, the film material is automatically flattened by the dual effects of the friction transmission of the drive wheel and the contour of the equipment, and the real-time correction of the monitoring system is coordinated to significantly improve the product appearance and transportation safety.

[0018] 3. In the present invention, the film-pulling mechanism clamps the film material through the cylinder and the drag roller, and the film-cutting mechanism is driven by the driving motor to drive the cutting knife to slide and cut the film. The driving mechanism synchronously drags the two to work together to improve the packaging efficiency.

[0019] 4. The suction cup of the dragging mechanism of the present invention adopts a porous negative pressure design, which can quickly absorb membranes of different materials to ensure that the membranes do not fall off during the stretching process. The damping rod and the V-shaped connector form a flexible hinge structure, which can automatically adjust the opening angle according to the tensile force of the membrane. When the thickness of the membrane changes, the elastic damper inside the damping rod can buffer the impact load and avoid tearing of the membrane due to rigid pulling, which is especially suitable for easily damaged aluminum-plated film or composite film packaging scenarios.

Specific embodiments

[0031] 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 embodiments.

[0032] Example 1, as Figure 1 ,Figure 2 , Figure 3 and Figure 4 As shown in ,

[0033] , an intelligent variable-ratio cold-stretching vertical film sleeving machine includes a protective fence 1, a control cabinet 2, and four hollow columns 4. The protective fence 1 is symmetrically distributed on both sides of the ground. The control cabinet 2 is installed outside the protective fence 1. The four hollow columns 4 are fixedly arranged in a rectangle on the ground and are all located inside the protective fence 1.

[0033] All of the above four hollow columns 4 are concave, which is convenient for installing structures such as sprockets 41 and chains 42 inside them, providing space for the operation of the chain 42.

[0034] A moving platform 5 slides on the outer surfaces of the four hollow columns 4. A conveying mechanism 3 is installed between the four hollow columns 4. On the left and right sides of the inner cavity bottom wall of the moving platform 5, a film pulling mechanism 6 and a film cutting mechanism 7 are respectively installed. On the outer surfaces of the two hollow columns 4 on the left and the outer surfaces of the two hollow columns 4 on the right, film transferring mechanisms 8 are respectively provided. Between the two film transferring mechanisms 8 on the same side, a dragging mechanism 9 is fixedly arranged. At the four corners of the inner cavity bottom wall of the moving platform 5, a driving mechanism 10 is provided.

[0035] During the implementation process, first, it is necessary to adjust the horizontal height of the moving platform 5 through a driving motor 43 etc. according to the height of the equipment to be sleeved with film. The moving platform 5 can drive the film transferring mechanism 8 and the dragging mechanism 9 to move synchronously. Put the barrel film into the film pulling mechanism 6, and the film pulling mechanism 6 moves the barrel film towards the direction of the equipment to be sleeved with film.

[0036] Place the equipment to be sleeved with film on the conveying mechanism 3. The conveying mechanism 3 moves the equipment to be sleeved with film between the four hollow columns 4. The driving mechanism 10 adjusts the positions of the film pulling mechanism 6 and the film cutting mechanism 7 so that they can be located directly above the equipment to be sleeved with film.

[0037] At this time, start the four film transferring mechanisms 8. The four film transferring mechanisms 8 move the two dragging mechanisms 9 closer to the barrel film. When the dragging mechanism 9 contacts the barrel film, the dragging mechanism 9 sucks the two sides of the barrel film. Through the reverse operation of the film transferring mechanism 8, the barrel film is torn apart, and subsequently, the barrel film can be smoothly sleeved on the equipment to be sleeved with film.

[0038] After the dragging mechanism 9 tears apart the barrel film, the height of the moving platform 5 is lowered through a driving motor 43 etc. so that the barrel film can be smoothly sleeved on the equipment to be sleeved with film. Subsequently, the dragging mechanism 9 separates from the barrel film. The film transferring mechanism 8 continues to operate and presses the barrel film on the equipment. Through the operation of the film transferring mechanism 8, the barrel film is dragged downward on the equipment to be sleeved with film. Through the expansion of the equipment to be sleeved with film, the downward-falling barrel film can be automatically expanded until the barrel film completely wraps the equipment to be sleeved with film. Start the film cutting mechanism 7 to horizontally cut the barrel film, completing the entire film sleeving process.

[0039] Specifically, to achieve the purpose of adjusting the horizontal height of the mobile platform 5 above, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , in this embodiment, sprockets 41 are rotatably installed on the upper and lower sides of the inner cavities of the four hollow columns 4. A chain 42 is commonly installed on the outer surfaces of the two sprockets 41 on the same side. A speed reducer 44 is commonly installed between the two hollow columns 4 on the left and right. The two output ends of the speed reducer 44 are respectively fixedly connected to the two sprockets 41 on the same side. A driving motor 1 43 is fixedly installed at the input end of the speed reducer 44. The mobile platform 5 is fixed inside the four chains 42 and is jointly driven by the four chains 42.

[0040] In this embodiment, the driving motor 1 43 transmits power to the speed reducer 44. After the power is decelerated and torque-increased by the speed reducer 44, it is transmitted to the two sprockets 41 at the lower part and finally transmitted to the chain 42 to drive the chain 42 to move around the two sprockets 41. The mobile platform 5 is installed on one side of the four chains 42. The movement of the chain 42 can jointly drag the mobile platform 5 to move synchronously, and thus the horizontal height of the mobile platform 5 can be adjusted;

[0041] The speed reducer 44 in this case has a locking function, such as a worm and worm gear speed reducer, to ensure that the current state can be maintained after the horizontal height of the mobile platform 5 and prevent it from sliding randomly.

[0042] Specifically, refer to Figure 10 , in this embodiment, the driving mechanism 10 includes a speed reducer 101, a driving motor 4 102, and two second shafts 103. The two second shafts 103 are respectively rotated on the left and right sides of the bottom wall of the mobile platform 5. Pulley 2s are fixedly installed at the front and rear ends of one of the second shafts 103. A second transmission belt 104 is commonly wound between the two pulley 2s on the same side. The second transmission belt 104 is used to simultaneously drag the film pulling mechanism 6 and the film cutting mechanism 7 to slide on the bottom wall of the inner cavity of the mobile platform 5. The driving motor 4 102 is installed at the input end of the speed reducer 101. One end of the other second shaft 103 is installed on one output end of the speed reducer 101. Pulley 2s are also installed at the other output end of the speed reducer 101 and at the end of the second shaft 103 far from the speed reducer 101.

[0043] In this embodiment, both the film pulling mechanism 6 and the film cutting mechanism 7 are installed on one side of the second transmission belt 104, and the film pulling mechanism 6 and the film cutting mechanism 7 are of an integrated structure. By running the driving motor 4 102, the film pulling mechanism 6 and the film cutting mechanism 7 can be simultaneously dragged to move and maintain the state after movement.

[0044] Specifically, to drag the barrel film to move onto the equipment to be film-covered, refer to Figure 8, in this embodiment, the film pulling mechanism 6 includes two first mounting frames 61 mounted on the front and rear sides of the bottom wall of the moving platform 5. A first roller 63 is rotatably mounted in the middle between the two first mounting frames 61. A second driving motor 62 for driving the first roller 63 is fixedly mounted in the middle of the rear end of the rear first mounting frame 61. A first shaft 64 is rotatably connected to the left part between the two first mounting frames 61. Connecting blocks 65 are fixedly mounted on the front and rear sides of the outer surface of the first shaft 64. A second roller 66 is rotatably mounted between the two connecting blocks 65. Cylinders 67 are symmetrically mounted on the left side of the bottom wall of the inner cavity of the moving platform 5 in the front and rear. The piston rods of the output ends of the two cylinders 67 are rotatably connected to the first shaft 64.

[0045] In this embodiment, reverse-start the two cylinders 67 to rotate the second roller 66 upward through the first shaft 64 and the connecting blocks 65 to separate it from the first roller 63. Place the barrel film between the second roller 66 and the first roller 63. Then, forward-start the two cylinders 67 to make the second roller 66 approach the first roller 63 again and clamp the barrel film. By operating the second driving motor 62, drive the first roller 63 to operate and drag the barrel film downward so that the barrel film can approach the equipment to be film-covered.

[0046] Furthermore, to achieve the purpose of cutting the barrel film, refer to Figure 9 , in this embodiment, the film cutting mechanism 7 includes two third driving motors 71. The two third driving motors 71 are both mounted on the front and rear sides of the right part of the bottom wall of the inner cavity of the moving platform 5. Pulley one is mounted on the output end of each of the two third driving motors 71. A first transmission belt 72 is wound around between the two pulley ones. A plurality of cutting knives 73 sliding on the bottom wall of the moving platform 5 are fixedly mounted on one side of the outer surface of the first transmission belt 72.

[0047] In this embodiment, the implementation process of the film cutting mechanism 7 is similar to that of the driving mechanism 10. Start the third driving motor 71 to drive the first transmission belt 72 to move through the pulley, and then drive a plurality of cutting knives 73 to slide in the front and rear directions to cut the barrel film.

[0048] Embodiment 2. On the basis of Embodiment 1, this embodiment expands the barrel film dragged by the film pulling mechanism 6 so that it can be sleeved on the equipment to be film-covered.

[0049] Specifically, to achieve the above purpose, refer to Figure 5 and Figure 7 , in this implementation, the dragging mechanism 9 includes a bracket 91 fixed on one side of the bottom of the moving platform 5. Double-layer fixing frames 93 are fixedly mounted on the front and rear sides of the upper end of the bracket 91. Damping rods 92 are rotatably mounted on the side close to each other inside the two double-layer fixing frames 93. V-shaped connectors 94 are rotatably mounted on the output ends of the two damping rods 92 on the same side double-layer fixing frames 93. Driving plates 95 are fixedly mounted on the sides away from each other of the two V-shaped connectors 94. Two suction cups 96 are mounted on the front and rear sides of the bracket 91.

[0050] Further, referring to Figure 5 and Figure 7 , in this embodiment, the film transfer mechanism 8 includes a second mounting frame 81 fixed below the driving plate 95 on the same side. An electric cylinder 82 is fixed to the upper part of the second mounting frame 81. A guide rod 83 slides on the upper end of the second mounting frame 81. A plurality of limiting wheels 84 for limiting the guide rod 83 are installed on one side of the second mounting frame 81 close to the bracket 91. A protective plate 85 is fixed to the output end piston rod of the electric cylinder 82. A first driving wheel 86 rotates on the upper part of the protective plate 85. A fifth driving motor 87 is fixed to one side of the upper part of the protective plate 85 close to the electric cylinder 82. The output end of the fifth driving motor 87 is fixed with a second driving wheel 88 that fits with the first driving wheel 86.

[0051] In the above, the two electric cylinders 82 on the same side move simultaneously, respectively driving the guide rods 83 on the same side to extend towards the dragging mechanism 9, and at the same time driving the protective plate 85, the first driving wheel 86, the fifth driving motor 87 and the second driving wheel 88 to move closer to the dragging mechanism 9 at the same time. During this process, the damping rod 92 for ensuring the stability of the bracket 91 can extend while rotating, moving the dragging mechanism 9 through the driving plate 95 in the reverse direction of the equipment to be film-covered. When the suction cup 96 contacts the barrel film, under the action of negative pressure, the barrel film is adsorbed on the suction cup 96. Subsequently, the four electric cylinders 82 run in the reverse direction, dragging the bracket 91 outwards and tearing the barrel film apart, exposing the internal space of the barrel film and covering it on the equipment to be film-covered;

[0052] Subsequently, the electric cylinder 82 continues to operate, pressing the barrel film on the equipment through the first driving wheel 86. By the operation of the fifth driving motor 87, the second driving wheel 88 and the first driving wheel 86 rotate synchronously. While the auxiliary film pulling mechanism 6 transports the barrel film, and in cooperation with the volume of the equipment to be film-covered, the barrel film is continuously dragged downwards, and the entire film covering process is completed. After the film covering is completed, the barrel film is cut off by the film cutting mechanism 7, and then the equipment with the film covering is transported out through the conveying mechanism 3.

[0053] Embodiment 3: Monitoring cameras are installed on the tops of both brackets 91. On the basis of Embodiment 2, this embodiment can monitor the volume of the equipment to be film-covered, the edge coordinates of the equipment, etc., perform three-dimensional modeling on the equipment to be film-covered, and transmit the data to the control cabinet 2. Subsequently, instructions can be issued through the control cabinet 2 to intelligently adjust the horizontal positions of the film-pulling mechanism 6 and the film-cutting mechanism 7, the horizontal height of the moving platform 5, and the extension length of the film-transferring mechanism 8. The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
