Description
Technical Field
[0001] The utility model relates to the technical field of packaging film wrapping, in particular to an automatic film wrapping device. Background Art
[0002] The commonly used film coating devices on the market are generally used for side film coating of objects, and the film coating operation is performed on the four sides of the object. The object is rotated by the base and the film feeding mechanism moving on the column is used to complete the film coating of the object. When the film coating device adopts this method to coat the six sides of the object, it often adopts the method of flipping to coat the whole object.
[0003] The inventor has found that the existing film coating device uses a clamp to hold the object and a rotating cylinder to drive the object to rotate when flipping the object. However, when flipping a large object, the power of the flipping mechanism is relatively large because it needs to be clamped and flipped. The existing film coating device cannot meet the flipping and coating requirements of large objects. Utility Model Content
[0004] The utility model aims to provide an automatic film coating device, which can turn over a large object, so as to fully coat all surfaces of the large object.
[0005] The embodiment of the utility model is achieved as follows:
[0006] The utility model provides an automatic film coating device, including a workbench, a film feeding mechanism and a flipping mechanism. The workbench is used to place objects to be coated, and can drive the objects to be coated to rotate. A groove is provided on the workbench for positioning the objects to be coated. The film feeding mechanism is located on one side of the workbench and is used to fix the roll film. The flipping mechanism includes a flipping plate and a hoisting mechanism. The flipping plate is installed on a side of the workbench away from the object to be coated entering and exiting the workbench, and can rotate relative to a horizontal plane to push the object on the workbench to flip. The hoisting mechanism is arranged above the workbench and is used to hoist the object to be coated.
[0007] The beneficial effects of the embodiments of the utility model are:
[0008] The automatic film wrapping device of the utility model is provided with a workbench and a film feeding mechanism. When the workbench rotates, the object rotates synchronously. The film is wrapped around the object, and the film feeding mechanism completes the film feeding while the object rotates, thereby completing the film wrapping work on the side of the object. Before completing the film wrapping work on the upper and lower sides of the object, the object needs to be turned over so that the upper and lower surfaces of the object are converted to the side. The turning plate pushes the object to rotate while turning it over. At the same time, the hoisting mechanism above lifts the side of the object and cooperates with the turning plate to complete the turning of the object.
[0009] The automatic film wrapping device of the utility model has a structure in which a flipping plate is provided for flipping, and a hoisting mechanism assists in lifting. When flipping an object, the flipping can be completed without completely lifting the object. Large objects can be flipped, so that all surfaces of the large objects can be fully coated.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] Please refer to Figure 1 and Figure 2 The present embodiment provides an automatic film coating device 100 for coating a large object. The automatic film coating device 100 includes a fixed frame 10, a workbench 20, a film feeding mechanism 30 and a flipping mechanism 40.
[0026] Specifically, the fixed frame 10 includes a base 11, a column 12 and a crossbeam 13. The base 11 is fixed on the ground. One end of the column 12 is fixedly connected to the base 11, and the other end is fixedly connected to the crossbeam 13. In this embodiment, the fixed frame 10 includes four columns 12, and the crossbeam 13 is a square frame structure. The four columns 12 are fixedly connected to the top corners of the crossbeam 13 respectively. In other embodiments, the columns 12 of the fixed frame 10 can be replaced with a side panel 312 structure, and the utility model does not limit the specific structure of the fixed frame 10.
[0027] The workbench 20 is used to place the object to be coated, and can drive the object to be coated to rotate. A groove 26 is provided on the workbench 20 for positioning the object. It can be understood that, in the present embodiment, when the outer edges and corners of the object abut against the groove 26, it means that the object is installed in place. In addition, when the workbench 20 drives the object to rotate, the edges and corners of the object abut against the groove 26 to prevent the object and the workbench 20 from sliding relative to each other. Specifically, in the present embodiment, the workbench 20 is fixedly arranged on the base 11. Optionally, in the present embodiment, the workbench 20 is arranged in the middle position between the columns 12. In other embodiments, the distance between the workbench 20 and the columns 12 may be different. As long as it can be ensured that the columns 12 are located on one side of the workbench 20, the present utility model does not limit the specific position of the workbench 20.
[0028] The film feeding mechanism 30 is located at one side of the workbench 20 and is used to fix the film roll. In this embodiment, the film feeding mechanism 30 is arranged on the column 12. It can be understood that the film is wound to form a film roll, which has a free end. When the object is placed on the workbench 20, the free end of the film roll is wound around the object. When the object rotates, the film roll can be pulled so that the film on the film roll is wound around the object.
[0029] The flipping mechanism 40 includes a flipping plate 41 and a hoisting mechanism 50. The flipping plate 41 is installed on the side of the workbench 20 away from the object to be coated and enters and exits the workbench 20, and can rotate relative to the horizontal plane to push the object to flip. It can be understood that the flipping plate 41 is first located in the horizontal plane and can abut against the bottom surface of the object. When the flipping plate 41 flips, it can drive the object to flip, and the bottom surface of the object continues to abut against the flipping plate 41. When the flipping plate 41 flips from the horizontal plane to the vertical plane, the bottom surface of the object also flips from the horizontal plane to the vertical plane. At this time, the bottom surface of the object is transformed into the side surface of the object, and the top surface opposite to the bottom surface is also synchronously transformed into the side surface of the object. At this time, the film feeding mechanism 30 is used to coat the bottom surface and top surface of the object before flipping, that is, the two sides of the object after flipping.
[0030] In this embodiment, the flip mechanism 40 further includes a support member 43. When the flip plate 41 is located on a horizontal plane, the support member 43 abuts against the flip plate 41. Specifically, the support member 43 is fixed on the base 11.
[0031] In order to assist the turning plate 41 to turn over, a hoisting mechanism 50 is arranged above the workbench 20. The hoisting mechanism 50 is used to hoist the coated object. It can be understood that the hoisting mechanism 50 is used to apply an upward force to one side of the object, so that the side of the object is turned over to become the top surface of the object.
[0032] It should be noted that the present embodiment is to perform flip coating on large objects. Since large objects have a large mass, it is difficult to use a structure such as a clamp 31 to lift the object for flipping. The present embodiment adopts a structure in which the flip plate 41 and the hoisting mechanism 50 cooperate with each other. There is no need to lift the object completely. When flipping, the object can contact the plane of the workbench 20, reducing the power consumption required to overcome the gravity of the object. However, the present utility model is not only suitable for the full coating of large objects, but also can take into account the full coating of small objects. The automatic coating device 100 of the present utility model is not limited to the volume and mass of the object to be coated.
[0033] Please refer to Figure 3 and Figure 4, the workbench 20 includes a rotating disk 21. The rotating disk 21 includes a fixed boss 22 and a rotating cover. The rotating cover is sleeved on the fixed boss 22. A rotating member is provided between the rotating cover and the fixed boss 22. The rotating member is used to drive the rotating cover to rotate relative to the rotating boss. Specifically, in this embodiment, in order to facilitate the rotation of the rotating disk 21, the fixed boss 22 is a cylindrical structure. Optionally, in this embodiment, the rotating cover is set as a circular cover body, and a circular groove is provided inside it, which is convenient for rotating with the fixed boss 22. In other embodiments, the rotating cover can be set to a square or other shape, as long as the groove provided inside is circular and can be matched with the fixed boss 22, the utility model does not limit the outer shape of the rotating cover. In this embodiment, the outer diameter of the fixed boss 22 is smaller than the diameter of the circular groove of the rotating cover, so that there is a gap between the fixed boss 22 and the rotating cover, which is convenient for setting the rotating member 23. Specifically, in this embodiment, the rotating member 23 is a roller. The roller is connected to the inner wall of the rotating cover through a bearing.
[0034] Furthermore, the workbench 20 also includes a lifting plate 24. The fixed boss 22 is fixedly arranged on the lifting plate 24. It is understandable that the roller can slide on the lifting plate 24 to drive the rotating cover to rotate relative to the fixed boss 22. In this embodiment, the concave-convex fit between the fixed boss 22 and the rotating cover can make the rotating axis of the rotating cover coincide with the axis of the fixed boss 22 to position the rotating cover. In addition to facilitating the setting of the rotating member 23, the gap between the fixed boss 22 and the rotating cover can also prevent the rotating cover from contacting and rubbing with the fixed boss 22.
[0035] Furthermore, a circular track (not shown) is also provided on the lifting plate 24 in this embodiment. Specifically, a circular groove 26 is provided on the lifting plate 24. It can be understood that the rollers are arranged along the internal intervals of the rotating cover, and the running track of the rollers is circular. The circular track is provided so that the rollers can roll in the circular track, further preventing the rotating cover from moving relative to the fixed boss 22 when rotating, and the rotating cover can be limited.
[0036] Optionally, in other embodiments, the rotating member 23 may also be arranged to roll on the side wall of the circular boss. As long as it can drive the rotating cover to rotate relative to the circular boss, the utility model does not limit the specific structure of the rotating member 23.
[0037] The lifting plate 24 in this embodiment can be lifted and lowered in the vertical direction. Specifically, a lifting mechanism 25 is provided below the lifting plate 24 to drive the lifting plate 24 to lift and lower. Optionally, in this embodiment, the lifting mechanism 25 adopts a scissor-type lifting structure. In other embodiments, a sleeve cylinder lifting structure can be adopted. As long as the lifting plate 24 can be moved up and down, the utility model does not limit the specific structural form of the lifting mechanism 25.
[0038] It is understandable that the object can be raised by providing the lifting plate 24. When the volume of the object is large, the lower surface area of the object is larger than the area of the workbench 20. Raising the object can prevent the part of the object that exceeds the workbench 20 from contacting and rubbing with other fixed parts, thereby avoiding the object from rotating relative to the workbench 20, thereby improving the coating effect of the object.
[0039] Please refer to Figure 2 and Figure 5 The film feeding mechanism 30 includes a vertical guide rail 33 and a clamp 31. The clamp 31 is slidably connected to the vertical guide rail 33. The clamp 31 is used to fix the film roll. A fixed shaft 313 is provided on the clamp 31. The film roll is sleeved on the fixed shaft 313. Specifically, in the present embodiment, the vertical guide rail 33 is fixed on the column 12. The clamp 31 can move in the vertical direction relative to the column 12. Specifically, the clamp 31 includes a clamp 31 body and a slider 32. The clamp 31 body includes clamps 311 arranged opposite to each other up and down and side plates 312 connected between the clamps 311. The slider 32 is fixed to the side of the side plate 312 away from the clamps 311. The slider 32 is slidably matched with the vertical guide rail 33. A fixed shaft 313 is fixedly connected between the clamps 311 arranged up and down. It can be understood that the film roll is cylindrical and can be sleeved on the fixed shaft 313. When the free end of the film roll is wrapped around an object and the object rotates, the film roll can be pulled to rotate relative to the fixed shaft 313, so that the film on the film roll is wrapped around the side of the object. Furthermore, the up and down movement of the clamp 31 can drive the film roll to move up and down. When the object rotates, the film roll moves up and down, and the object can be wrapped from top to bottom.
[0040] Please refer to Figure 1 and Figure 2 , the automatic film wrapping device 100 also includes a fixed platform 14. The fixed platform 14 is fixed on the base 11 and has a certain height relative to the base 11. The workbench 20 can be located at the same height as the fixed platform 14. In this embodiment, the height of the fixed platform 14 is set to the height at which the workbench is completely lowered. Specifically, the flip plate 41 is hinged with the fixed platform 14. It can be understood that the flip plate 41 is rotatably connected to one end of the fixed platform 14, and it can rotate relative to the fixed platform 14. When the four sides of the object are wrapped, the cabinet object needs to be flipped, and the workbench 20 is completely lowered so that the bottom surface of the object abuts against the fixed platform 14, that is, the object is supported by the fixed platform 14, the workbench 20 and the flip plate 41 at the same time. At this time, the flip plate 41 is located in a horizontal plane, a part of the object is located on the flip plate 41, and the remaining part of the object is on the fixed platform 14 and the workbench 20. When the flip plate 41 rotates relative to the fixed platform 14, the object can be flipped under the action of the flip plate 41.
[0041] Furthermore, when the object is turned over, the edge of the object is located in the groove 26 on the workbench 20. The provision of the groove 26 can prevent the object from sliding downward when turning over. It is understandable that when the turning plate 41 rotates relative to the fixed platform 14 along the hinge point, the object can rotate relative to the workbench 20 around the groove 26, and at this time, the groove 26 is located on the rotation axis of the object.
[0042] Please refer to Figure 1 , Figure 6 and Figure 7 The hoisting mechanism 50 includes a rope winder 51 and a driving member (not shown). The rope winder 51 is fixed above the workbench 20. A rope 53 is wound around the rope winder 51. A hook 54 is provided at the free end of the rope 53. The driving member is used to drive the rope winder 51 to rotate so that the rope winder 51 releases or retracts the rope 53.
[0043] Specifically, the rope winder 51 is fixed on the crossbeam 13. Optionally, in this embodiment, the rope winder 51 is located directly above the workbench 20. In other embodiments, the rope winder 51 can be arranged above the side of the workbench 20, as long as the hoisting of the object can be achieved, and the utility model does not limit this.
[0044] Furthermore, the rope winder 51 is a cylindrical structure, which includes a fixed cylinder 511 and a rope tying plate 512 connected to both sides of the fixed cylinder 511. An axial hole 513 for connecting a driving member is provided in the fixed cylinder 511. Specifically, the driving member can be a motor to drive the rope winder 51 to rotate. A fixing ring 514 for fixing the rope 53 is provided on the fixed cylinder 511. It can be understood that one end of the rope 53 is fixed to the outer wall of the fixed cylinder 511 through the fixing ring 514, and the rope tying plate 512 on which the rope 53 is wound is used to limit the width of the rope 53 after winding. A hook 54 is fixed to the end of the rope 53 away from the fixed cylinder 511 for hoisting objects.
[0045] Furthermore, the hoisting mechanism 50 further includes a rope storage bin 52. The rope winding device 51 is located in the rope storage bin 52. A rope outlet is provided on the rope storage bin 52. The free end of the rope 53 away from the fixing tube 511 extends out of the rope outlet. The rope storage bin 52 is provided to limit the height of the rope 53 and prevent the rope 53 from falling freely.
[0046] Optionally, in this embodiment, the rotation axis of the rope winder 51 is set to a vertical direction, that is, the rope 53 is wound in the water surface. In other embodiments, the rotation axis of the rope winder 51 can be set to a horizontal direction, that is, the rope 53 is wound in the vertical direction. In this embodiment, two ropes 53 are wound around the rope winder 51 at the same time. In other embodiments, one or more ropes 53 can be set as needed. As long as the hoisting of the object can be achieved, the present invention is not limited to this.
[0047] Please refer to Figure 1 and Figure 2 , the automatic coating device 100 also includes a conveying mechanism 60. The conveying mechanism 60 includes a first conveying member 61. Specifically, the first conveying member 61 and the flip plate 41 are located on both sides of the workbench 20. One end of the first conveying member 61 is connected to the workbench 20. The first conveying member 61 is used to transport the object to be coated to the workbench 20 so that the first end of the object to be coated is engaged with the groove 26. Specifically, the first conveying member 61 is a conveyor belt mechanism, and is tilted between the base 11 and the workbench 20, and is used to move the object from the lower base 11 to the higher workbench 20. When the first end of the object is engaged with the groove 26, it is moved into place, and the next coating work can be performed. Optionally, in other embodiments, the first conveying member 61 can be a roller machine or a chain conveyor or other structure, which is not limited by the utility model.
[0048] Furthermore, the conveying mechanism 60 also includes a second conveying member 62. The second conveying member 62 is located on the side of the workbench 20, and the conveying direction of the second conveying member 62 is consistent with the direction in which the object to be coated enters and exits the workbench. Specifically, in the present embodiment, the conveying directions of the first conveying member 61 and the second conveying member 62 are consistent. The second conveying member 62 is used to drive the object to be coated to move on the workbench 20 so that the second end of the object to be coated is engaged with the groove 26. It is understandable that when the object needs to be flipped, part of the object must first be moved to the flip plate 41, and the second conveying member 62 is used to adjust the position of the object so that part of it is located on the flip plate 41 for easy flipping. Optionally, in other embodiments, the first conveying member 61 can be a roller machine or a chain conveyor or other structures, and the utility model is not limited to this.
[0049] The beneficial effects of the automatic film coating device 100 of the utility model are:
[0050] The automatic film coating device 100 of the utility model is provided with a workbench 20 and a film feeding mechanism 30. When the workbench 20 rotates, the object rotates synchronously. The object is wrapped with a film, and the film feeding mechanism 30 completes the film feeding while the object rotates, thereby completing the film coating work on the side of the object. Before completing the film coating work on the upper and lower sides of the object, the object needs to be turned over so that the upper and lower surfaces of the object are converted to the side. The flip plate 41 pushes the object to rotate while flipping. At the same time, the upper hoisting mechanism 50 lifts the side of the object and cooperates with the flip plate 41 to complete the flipping of the object.
[0051] The automatic coating device 100 of the utility model is flipped by setting a flip plate 41, and the hoisting mechanism 50 assists in lifting. When flipping an object, it is not necessary to lift the object completely to complete the flipping. Large objects can be flipped, so that all surfaces of the large objects can be fully coated.
[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
