Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a film winding packaging machine. Background Art

[0002] In modern industrial production and logistics transportation, the packaging of products not only concerns the appearance display of commodities, but also is an important means to ensure the safety of goods and reduce losses. Especially during the handling and storage of large quantities of goods, how to effectively and firmly package stacked products has become one of the key concerns of enterprises.

[0003] The traditional packaging method is to use a film packaging machine to wind and package the products stacked together. By continuously winding the packaging film around the outside of the products on the pallet, multiple products are formed into a whole to facilitate forklift handling and subsequent transportation work. When the traditional packaging machine is in use, the film roll on it generally moves in a horizontal circular motion, and it cannot effectively wind and package the top of the products stacked together, resulting in the products at this position being exposed, affecting the packaging strength and effect. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a film winding packaging machine, and the specific technical solution adopted is as follows:

[0005] According to a first aspect of the present invention, there is provided a film winding packaging machine, including a frame structure and a winding structure;

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral 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, and it can be the communication inside two elements. For those of ordinary skill in the art, 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.

[0031] As Figures 1 to 5 shown, a film winding packaging machine of the present invention includes a frame structure and a winding structure;

[0032] The frame structure includes a base 1 located 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-shaped frame 6 is arranged inside the gantry 5, and the arc-shaped frame 6 can move vertically on the gantry 5. The base 1 is used to carry a tray 4;

[0033] The winding structure includes a moving seat 7 slidably arranged on the arc-shaped 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;

[0034] Wherein, when the moving seat 7 moves on the arc-shaped frame 6, the inclination angle of the film roll 9 changes, and the film output by the film roll 9 winds around the top and side of the product on the tray 4.

[0035] Specifically, the tray 4 is placed inside the turntable 3 on the base 1. The products are palletized on the tray 4 to form a square whole. When the moving seat 7 inclines on the arc-shaped frame 6, the film roll 9 is also in an inclined state. The rotation of the support arm 8 drives the film roll 9 to rotate synchronously. At this time, due to the inclination of the film roll 9, the film roll 9 will wind the top and side surfaces of the whole products on the tray 4. That is, when the film output by the film roll 9 winds the right side of the top of the product, due to the inclination of the film roll 9 and relying on the support arm 8 to rotate on the moving seat 7, the film roll 9 synchronously winds the lower side of the right side surface of the product. As the moving seat 7 slides on the arc-shaped frame 6 towards the middle of the arc-shaped frame 6, the inclination angle of the film roll 9 gradually increases. At this time, the film output by the film roll 9 gradually winds from the right side to the left side of the product top surface and covers it. At the same time, the film output by the film roll 9 gradually winds from the lower side of the right side surface of the product to the upper side of the right side surface of the product. In this way, the top surface and one side surface of the product can be packaged. Then, the turntable 3 rotates 90° on the guide rail 2, and the winding work is repeated, so as to wind the top surface and the other side surface of the product. And so on, the comprehensive winding and packaging work of the product is realized.

[0036] Of course, after the winding work on each surface of the product is completed, it is necessary to make the film roll 9 vertical and perform a horizontal circular motion around the product, and cooperate with the vertical movement of the arc-shaped frame 6 on the gantry 5, so as to wind the four side surfaces 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 randomly, a common damping structure can be configured on it to make it output the film smoothly.

[0037] During use, first press one end of the film output from the film roll 9 on the surface of the product on the tray 4, and then rotate the support arm 8 to drive the film roll 9 to perform a rotary motion in an inclined state. The film output by the film roll 9 winds the top surface and the side surface of the product, and pushes the moving seat 7 to slide on the arc-shaped frame 6 and move towards the middle of the arc-shaped frame 6, so that the film completely covers the top surface of the product, and winds each side surface of the product in turn, and when winding the side surface, it winds the top surface of the product cooperatively, thus completing the packaging work of the product.

[0038] This solution realizes the simultaneous winding of the top and side surfaces of the product by adjusting the angle of the film roll 9, solves the problem that the traditional packaging machine can only wind horizontally, and improves the integrity and firmness of packaging; the moving seat 7 can slide on the arc-shaped frame 6, and the film roll 9 can also rotate with the support arm 8. Such a design enables the packaging machine to adapt to products of different sizes and shapes and enhances the applicable range of the equipment.

[0039] Furthermore, the shape of the guide rail 2 is arc-shaped, and the shape of the turntable 3 is arc-shaped.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] Specifically, when the film roll 9 is performing the packaging work, the film output by the film roll 9 is continuously wound around the product. After the packaging work is completed, the adjustment structure adjusts the rubber column 16 and the toothed knife 17 between the film roll 9 and the product. The film output by the film roll 9 will adhere to 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. Rotate the turntable 3 to make the arc-shaped frame 6 carry 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 wind the next group of products, since the end of the film is adsorbed on the rubber column 16, the film roll 9 runs and winds the film around the product, thus avoiding the operation of workers fixing the end of the film output by the film roll 9 in the traditional method. When the film winds around once, 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. The adjustment structure retracts the rubber column 16 and the toothed knife 17, so as to run the film roll 9 to continuously wind and package the product. This structural method can realize the continuous and automatic winding and packaging work of the product.

[0047] 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, and the toothed knife 17 is fixed on the support plate 18. Two adjustment plates 19 are inclined and rotatably arranged on the side wall of the support plate 18. The two adjustment plates 19 are parallel. 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.

[0048] A base 22 is fixed on the arc-shaped frame 6. Both of the two adjustment plates 19 are rotatably installed on the base 22. One of the adjustment plates 19 is connected to the base 22 through a cylinder 23.

[0049] Specifically, the fixed end of the cylinder 23 is rotatably installed on the base 22, and the movable end of the cylinder 23 is rotatably connected to one of the adjustment plates 19. When the cylinder 23 expands and contracts, it will drive the adjustment plate 19 to rotate on the base 22, thereby adjusting the position of the support plate 18. The parallel arrangement of the two adjustment plates 19 will limit the directions 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 adjustment plate 19 decreases. At this time, the top plate 20 on one of the adjustment plates 19 will move towards the top wheel 21 and abut against each other. The rubber column 16 cannot rotate, thereby enabling the rubber column 16 to maintain the adhesion and fixing effect on the film end. When it is necessary to release the film, just move the rubber column 16 towards 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 drive the rubber column 16 to rotate by pulling the film, and the rubber column 16 gradually releases the film. At this time, the film roll 9 rotates one week and approaches the rubber column 16 again.

[0050] Further, two driving wheels 24 are rotatably arranged on the base 1, and the two driving wheels 24 are driven by a transmission belt 25. A second motor 26 for providing power to one of the driving wheels 24 is arranged on the base 1;

[0051] Teeth are arranged on the outer wall of the turntable 3, and gears 27 are meshed on both the left and right sides of the turntable 3. The two gears 27 are respectively drivingly connected to the two driving wheels 24.

[0052] Specifically, the second motor 26 drives the two driving wheels 24 and the transmission belt 25 to run synchronously. At this time, the two driving wheels 24 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-shaped frame 6 and the film roll 9.

[0053] Further, sliding seats 28 are vertically slidably arranged on both the left and right sides inside the gantry 5. The two ends of the arc-shaped frame 6 are respectively fixedly connected to the two sliding seats 28. A threaded rod 29 is vertically inserted through each sliding seat 28. The threaded rod 29 is threadedly connected to the sliding seat 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.

[0054] Specifically, the sliding seat 28 is vertically slidably mounted on the gantry 5, thereby supporting the arc-shaped frame 6 through the sliding seat 28. The threaded rod 29 is rotatably mounted on the gantry 5, and the third motor 30 is fixed on the gantry 5. The third motor 30 can push the sliding seat 28 to move up and down through the threaded rod 29, thereby adjusting the height position of the arc-shaped frame 6.

[0055] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
