[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 5 As shown, a film wrapping packaging machine of the present invention comprises a frame structure and a wrapping structure; The frame structure includes a base 1 at the bottom, a guide rail 2 installed on the base 1, a turntable 3 rotatably installed on the guide rail 2, and a gantry 5 fixed on the upper surface of the turntable 3, an arc frame 6 is arranged inside the gantry 5, and the arc frame 6 can move in the vertical direction on the gantry 5, and the base 1 is used to carry the tray 4; The winding structure includes a moving seat 7 slidably arranged on an arc frame 6, a support arm 8 is rotatably arranged on the moving seat 7, a film roll 9 is arranged at the end of the support arm 8 away from the moving seat 7, and the film roll 9 can rotate on the support arm 8; When the moving seat 7 moves on the arc frame 6 , the inclination angle of the film roll 9 changes, and the film output by the film roll 9 is wound around the top and side of the product on the tray 4 .

[0020] In detail, the pallet 4 is placed on the inner side of the turntable 3 on the base 1, and the products are stacked on the pallet 4 to form a square whole. When the moving seat 7 is tilted on the arc frame 6, the film roll 9 is also in a tilted state, and the rotation of the support arm 8 will drive the film roll 9 to rotate synchronously. At this time, due to the tilt of the film roll 9, the film roll 9 will wrap around the entire top and side of the product on the pallet 4, that is, when the film output by the film roll 9 wraps around the right side of the top of the product, due to the tilt of the film roll 9 and relying on the support arm 8 to rotate on the moving seat 7, the film roll 9 will synchronously wrap around the lower side of the right side of the product Winding, as the movable seat 7 slides on the arc frame 6 toward the middle of the arc frame 6, the inclination angle of the film roll 9 gradually increases. At this time, the film output by the film roll 9 is gradually wrapped and covered from the right side of the top surface of the product to the left, and at the same time, the film output by the film roll 9 is gradually wrapped and covered from the lower side of the right side of the product to the upper side of the right side of the product. In this way, the top surface and one side surface of the product can be packaged, and the turntable 3 is rotated 90° on the guide rail 2, and the winding work is repeated, so as to wrap the top surface and the other side surface of the product, and so on, to achieve comprehensive winding and packaging of the product.

[0021] Of course, after completing the winding work on each surface of the product, it is necessary to make the film roll 9 vertical and move horizontally in a circular motion around the product, and cooperate with the vertical movement of the arc frame 6 on the gantry 5 to wrap the four sides of the product. This can strengthen the winding work and prevent the film on the top of the product from slipping. In order to prevent the film roll 9 from rotating at will, a common damping structure can be configured on it to enable it to output the film smoothly.

[0022] When in use, first press one end of the output film on the film roll 9 against the surface of the product on the tray 4, then rotate the support arm 8 to drive the film roll 9 to rotate in an inclined state, and the film output by the film roll 9 is wrapped around the top and side surfaces of the product, pushing the movable seat 7 to slide on the arc frame 6 and move toward the middle of the arc frame 6, so that the film fully covers the top surface of the product, and then wraps each side of the product in turn, and the top surface of the product is wound together when the side is wound, thereby completing the product packaging work.

[0023] This solution achieves simultaneous winding of the top and sides of the product by adjusting the angle of the film roll 9, solving the problem that traditional packaging machines can only wrap horizontally, and improving the integrity and firmness of the packaging; the movable seat 7 can slide on the arc frame 6, and the film roll 9 can also rotate with the support arm 8. This design enables the packaging machine to adapt to products of different sizes and shapes, enhancing the applicability of the equipment.

[0024] Furthermore, the guide rail 2 is arc-shaped, and the turntable 3 is arc-shaped.

[0025] In detail, the arc of the guide rail 2 and the arc of the turntable 3 are both larger than a semicircle, so that when the arc opening of the guide rail 2 and the arc opening of the turntable 3 coincide, a unloading channel is formed, which facilitates a forklift to reach into the turntable 3 and shovel up the pallet 4, and this structural method does not affect the normal rotation of the turntable 3 on the guide rail 2.

[0026] Furthermore, a guide strip 10 is provided on the inner wall of the arc frame 6, and the movable seat 7 is slidably installed on the guide strip 10. The side surface of the guide strip 10 is set to be conical, and a first motor 11 is provided on the side wall of the movable seat 7. A first conical wheel 12 is provided at the output end of the first motor 11, and the first conical wheel 12 is located on the inner side of the movable seat 7. One side of the conical surface of the first conical wheel 12 is transmission-connected to the conical surface of the guide strip 10, and the other side of the conical surface of the first conical wheel 12 is transmission-connected to the second conical wheel 13, and the second conical wheel 13 is transmission-connected to the support arm 8.

[0027] In detail, the first motor 11 can drive the first cone wheel 12 to rotate, and the first cone wheel 12 can roll on the guide bar 10, so that the movable seat 7 slides on the guide bar 10, and the movable seat 7 moves along the trajectory of the arc frame 6. The first cone wheel 12 synchronously drives the second cone wheel 13 to rotate, thereby driving the support arm 8 to rotate, so as to facilitate the film roll 9 to perform a circular motion. In this way, the film roll 9 can move along the trajectory of the arc frame 6 while performing a circular motion, so that the film output by the film roll 9 can gradually and fully cover the top and side surfaces of the product while wrapping around the top and sides of the product.

[0028] Furthermore, the support arm 8 is composed of a sleeve 14 and a slide rod 15. The slide rod 15 is slidably inserted into the sleeve 14, and the slide rod 15 and the sleeve 14 are fastened by bolts. The sleeve 14 is rotatably mounted on the movable seat 7 and is transmission-connected to the second cone wheel 13, and the film roll 9 is rotatably mounted on the slide rod 15.

[0029] In detail, the slide bar 15 is perpendicular to the support arm 8. By combining the sleeve 14 and the slide bar 15, the length of the support arm 8 can be adjusted, thereby facilitating the adjustment of the rotation radius of the film roll 9 and facilitating the packaging of products of different sizes.

[0030] Furthermore, an adjustment structure is provided on the arc frame 6, and a rubber column 16 and a toothed knife 17 are provided at the output end of the adjustment structure. The adjustment structure is used to adjust the positions of the rubber column 16 and the toothed knife 17. The rubber column 16 is used for bonding the film, and the toothed knife 17 is used for cutting the film between the film roll 9 and the product.

[0031] In detail, when the film roll 9 is performing the packaging work, the film output by the film roll 9 is continuously wound around the product. When the packaging work is completed, the adjusting structure adjusts the rubber column 16 and the toothed knife 17 to between the film roll 9 and the product, and the film output by the film roll 9 will fit with the outer wall of the rubber column 16. The rubber column 16 adsorbs and fixes the film, and the film contacts the toothed knife 17. The turntable 3 is rotated so that the arc frame 6 carries the toothed knife 17 to pull the film. The toothed knife 17 will cut the film, and the product completes the film winding work. When it is necessary to wrap the next group of products, since the end of the film is adsorbed on the rubber column 16, the film roll 9 runs and wraps the film around the product, thereby avoiding the operation of fixing the end of the film output by the film roll 9 in the traditional method. When the film is wrapped around, the film roll 9 moves to the position of the rubber column 16 again. At this time, the rubber column 16 rotates and releases the film, and the adjusting structure retracts the rubber column 16 and the toothed knife 17, thereby running the film roll 9 to continuously wrap and package the product. This structural method can realize continuous and automatic winding and packaging of products.

[0032] Further, the adjustment structure includes a support plate 18 located at the bottom of the rubber column 16, the rubber column 16 rotates on the support plate 18, the toothed knife 17 is fixed on the support plate 18, and two adjustment plates 19 are arranged on the side wall of the support plate 18 for tilting and rotating. The two adjustment plates 19 are parallel, and a top plate 20 is fixed on one of the adjustment plates 19. A top wheel 21 is arranged on the rubber column 16. When the top plate 20 abuts against the top wheel 21, the rubber column 16 is locked; A base 22 is fixed on the arc frame 6 , and two adjustment plates 19 are rotatably mounted on the base 22 . One adjustment plate 19 is connected to the base 22 via a cylinder 23 .

[0033] In detail, the fixed end of the cylinder 23 is rotatably mounted on the base 22, and the movable end of the cylinder 23 is rotatably connected to an adjusting plate 19. When the cylinder 23 is extended or retracted, it will drive the adjusting plate 19 to rotate on the base 22, thereby adjusting the position of the supporting plate 18, and the parallel arrangement of the two adjusting plates 19 will limit the direction of the rubber column 16 and the toothed knife 17. When the rubber column 16 gradually moves to the working position, the inclination angle of the adjusting plate 19 decreases. At this time, the top plate 20 on an adjusting plate 19 will move toward the top wheel 21 and abut against each other, and the rubber column 16 cannot rotate, thereby keeping the rubber column 16 adhering to the fixing effect of the end of the film. When the film needs to be released, it only needs to move the rubber column 16 toward the retracted position to separate the top plate 20 and the top wheel 21. Since the film has been wound around the product, the product will pull the rubber column 16 to rotate through the film, and the rubber column 16 gradually releases the film. At this time, the film roll 9 rotates one circle and approaches the rubber column 16 again.

[0034] Furthermore, two transmission wheels 24 are rotatably provided on the base 1, and the two transmission wheels 24 are driven by a transmission belt 25, and a second motor 26 for providing power to one transmission wheel 24 is provided on the base 1; The outer wall of the turntable 3 is provided with teeth, and the left and right sides of the turntable 3 are both meshed with gears 27 , and the two gears 27 are respectively connected to the two transmission wheels 24 in transmission.

[0035] In detail, the second motor 26 will drive the two transmission wheels 24 and the transmission belt 25 to run synchronously. At this time, the two transmission wheels 24 will drive the turntable 3 to rotate on the guide rail 2 through the two gears 27, thereby facilitating the adjustment of the directions of the arc frame 6 and the film roll 9.

[0036] Furthermore, slides 28 are vertically slidably arranged on both sides of the left and right sides of the gantry 5, and both ends of the arc frame 6 are fixedly connected to the two slides 28 respectively. A threaded rod 29 is vertically inserted into each slide 28, and the threaded rod 29 is threadedly connected to the slide 28. A third motor 30 is arranged at the end of the threaded rod 29, and the third motor 30 provides rotational power for the threaded rod 29.

[0037] In detail, the slide 28 is vertically slidably installed on the gantry 5, thereby supporting the arc frame 6 through the slide 28, the threaded rod 29 is rotatably installed on the gantry 5, and the third motor 30 is fixed on the gantry 5. The third motor 30 can push the slide 28 to move up and down through the threaded rod 29, thereby adjusting the height position of the arc frame 6.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
