Description

Technical Field

[0001] This invention relates to winding machines, and more particularly to the columns of winding machines. Background Technology

[0002] A wrapping machine is a type of machinery used in packaging equipment to wrap packaging film around the surface of goods. It consists of a column, a base, and a turntable. The turntable is rotatably mounted on the base. Goods are placed on the turntable and rotate with it, thus wrapping the packaging film around their surface. The column is mounted at one end of the base and houses the lifting film frame, its lifting mechanism, and electrical control components. In traditional column structures, an internal rectangular frame is required. This rectangular frame is elongated, with panels installed on its four sides. The motor and upper sprocket of the lifting mechanism are mounted on the frame. Wrapping machines are assembled on-site, which means that the elongated frame takes up significant transport volume and also encroaches on the internal space of the column. Summary of the Invention

[0003] The purpose of this invention is to provide a column mechanism that reduces transport volume and, for a column of the same size, provides a larger internal space. To this end, this invention adopts the following technical solution: A column structure includes a column and a lifting mechanism mounted on the column, characterized in that the column adopts a columnless internal frame structure, and is assembled from wall panels as load-bearing structures to form a wall panel column, wherein the wall panel column comprises multiple wall panels connected in sequence in the height direction.

[0004] Based on the above technical solutions, the present invention may also employ the following further technical solutions, or combine these further technical solutions: The column mechanism includes two wall panel columns arranged side by side.

[0005] The wall panel includes a first side and a second side arranged at right angles, wherein the first side is the side where the lifting device is located.

[0006] The wall panel also includes a third side, which is located opposite the first side.

[0007] The third surface is narrower than the first surface, with one side longer than the other, and a bottom surface is provided between the two sides. The longer side is located on the side corresponding to the lifting and lowering of the membrane frame. A gap is left between the first surfaces of the two wall panel columns, and the supply and demand lifting device is connected to the lifting mechanism inside the column mechanism.

[0008] The column mechanism is equipped with a top support plate. The bottom of the two wall panel columns is connected to a fixed plate, and the top of the two wall panel columns is connected to the top support plate. The top structure of the lifting mechanism is fixed to the top support plate.

[0009] The top structure includes a top sprocket and a motor.

[0010] The column mechanism is also equipped with a lifting guide rail, which is assembled and connected to the wall panel.

[0011] On the opposite side of the first side, a column inspection port is formed on the two wall panel columns, and a cover plate for the inspection port is installed.

[0012] The upper and lower ends of the wall panel are respectively provided with connecting plates and positioning connecting holes are provided on the connecting plates. The upper and lower adjacent wall panels are connected by the connecting plates. The top wall panel is connected to the top support plate by the connecting plate at its upper end, and the bottom wall panel is connected to the bottom fixing plate by the connecting plate at its lower end.

[0013] The column mechanism is equipped with a top support plate. The bottom of the two wall panel columns is connected to the fixed plate, and the top of the two wall panel columns is connected to the top support plate. The upper and lower ends of the wall panels are respectively provided with connecting plates and positioning connecting holes are provided on the connecting plates. The upper and lower adjacent wall panels are connected by the connecting plates through a connecting structure. The top wall panel is connected to the top support plate through the connecting plate at its upper end, and the bottom wall panel is connected to the bottom fixed plate through the connecting plate at its lower end.

[0014] A detachable horizontal connector is provided between the facing connecting plates of the two wall panel columns.

[0015] Because of the technical solution of this invention, the column mechanism of this invention can eliminate the need for a column frame, while maintaining a stable structure, ensuring overall strength and reliable operation of the lifting mechanism. At the same time, it can reduce the transportation volume, and has a larger internal space, making maintenance more convenient. Attached Figure Description

[0020] Figure 5 This is a schematic diagram of Embodiment 3 of the present invention. Detailed Implementation

[0021] See attached document Figures 1-3This invention provides a column mechanism, including a column and a lifting mechanism 300 mounted on the column. The column adopts a column-less internal frame structure, instead being assembled from wall panels 1, which serve as load-bearing structures, to form a wall panel column 100. The wall panel column comprises multiple wall panels 1 connected sequentially in the height direction. During transportation, it is transported in an unassembled state, and there is no need to transport the previously required full-length frame column; therefore, the volume can be greatly reduced.

[0022] In this embodiment, the column mechanism includes two wall panel columns 100 arranged side by side, and a top support plate is provided on the column mechanism. In a preferred embodiment, the column mechanism includes two wall panel columns arranged facing each other.

[0023] The wall panel includes a first surface 11 and a second surface 12 arranged at right angles, wherein the first surface 11 is the surface where the lifting device (i.e., the lifting membrane frame 200) is located. The wall panel also includes a third surface 13, which is located opposite the first surface 11. In a preferred embodiment, the wall panel 1 has a U-shaped cross-section, meaning the bottom surface of the wall panel with the U-shaped cross-section is also the second surface 12, thus strengthening both the wall panel structure and the stability of the column mechanism. The column mechanism is equipped with a top support plate. The bottoms of the two wall panel columns 100 are connected to the fixing plate 2, and the tops of the two wall panel columns 100 are connected to the top support plate 3, forming a stable frame structure. The top structure of the lifting mechanism 300 is fixed to the top support plate 3 via a top fixing seat 31. The lifting power is installed on the top support plate 3, eliminating the need for internal supports in the columns, reducing the overall column volume, making it lighter and saving transportation space. The connection structure between the top fixing seat 31 and the top support plate 3 can use a snap-fit ​​welding method plus fastener locking to ensure a stable and reliable connection. The bottom structure of the lifting mechanism 300 is fixed to the bottom fixing plate 2 via a bottom fixing seat 21.

[0024] The wall panel with a U-shaped cross-section has one side longer than the other, meaning the first side 11 is wider than the third side 13. A gap 10 is left between the first sides 11 of the U-shaped wall panels of the two wall panel columns 100 to allow the lifting membrane frame 200 to connect with the lifting mechanism 300 within the column mechanism. The lifting mechanism 300 can be a chain mechanism. The top structure of the lifting mechanism 300 includes a top sprocket 301 and a motor 302.

[0025] The lifting guide rail section 700 can be detachably connected (e.g., by screw connection) to the two wall panel columns 100, and when assembled with adjacent wall panels, the lifting guide rail section 700 is connected to form a full-length lifting guide rail. The lifting guide rail is installed in sections on the supporting wall panel 1, which facilitates installation and disassembly.

[0026] Another major advantage of the aforementioned U-shaped structure is that it facilitates internal maintenance of the column mechanism. A column maintenance opening 14 is formed between the third surfaces 13 of the wall panels 1, which have a U-shaped cross-section, and a cover plate 4 for the maintenance opening is installed on the third surface 13. The end of the first surface 11 has a corner 111, while the end 121 of the third surface 13 does not, further facilitating internal maintenance of the column mechanism.

[0027] The upper and lower ends of each wall panel are respectively provided with connecting plates 5, and positioning connection holes 51 are provided on the connecting plates 5. Adjacent wall panels are connected by the connecting plates 5 through a connecting structure. The top wall panel is connected to the top support plate 3 through the connecting plate 5 at its upper end, and the bottom wall panel is connected to the bottom fixing plate 2 through the connecting plate 5 at its lower end. All connections can be made with screws. A detachable horizontal connecting piece 6 (e.g., by screws) is connected between the facing connecting plates 5 of the two wall panel columns 100 to make the connection more reliable and stable. The connecting structure can be implemented during on-site assembly using the winding machine.

[0028] Furthermore, the wall panel may also consist only of a first surface 11 and a second surface 12, in which case the cross-sectional shape is L-shaped. The connecting plate 5 may also be formed by welding onto the wall panel 1 or by bending the end of the wall panel 1.

[0029] In the diagram, reference numeral 400 represents the winding machine turntable, reference numeral 600 represents the control box, and reference numeral 500 represents the turntable rotation drive device. (See also...) Figure 2 , 4 The length of the control box 600 can be longer than the length of the wall panel located in the middle of the wall panel column. Therefore, when the control box 600 is installed on the wall panel column, it can be connected to the middle of the wall panel column on one side, but its length can overlap with the middle wall panel of the wall panel column, and partially overlap with the wall panel above and below the middle wall panel, thus playing a certain role in structural reinforcement.

[0030] Reference Figure 4 In this embodiment, the lifting guide rail is a full-length, continuous lifting guide rail 700A, which is connected to multiple wall panels 1 on the wall panel column, thus providing a certain structural reinforcement. The continuous lifting guide rail 700A may have a notch 701 to accommodate the aforementioned connecting plate 5. In addition, in this embodiment, a transverse connecting member 6 may or may not be provided.

[0031] The other parts of this embodiment are the same as those in the previous embodiment.

[0032] Reference Figure 5In this embodiment, the structure of the column mechanism can adopt the implementation method of the aforementioned embodiment. Furthermore, the control box 600B is positioned on the opposite side of the first surface 11, i.e., opposite the lifting membrane frame, which also provides a balancing effect for the entire mechanism. The length of the control box 600B can overlap with the middle wall panel of the wall panel column, and partially overlap with the wall panels above and below the middle wall panel, thus providing a certain structural reinforcement. The control box 600B is detachably connected to the wall panel 1, and the upper and lower covers of the control box 600B can serve as inspection ports.
