Description
[0001] Priority declaration
[0002] This application claims the priority of the Chinese patent application filed with the China Patent Office on April 12, 2024, with application number CN2024207639640 and invention name “Film filling mechanism and packaging equipment”, all contents of which are incorporated by reference in this application. Technical Field
[0003] The utility model relates to the field of packaging, in particular to a film filling mechanism and packaging equipment. Background Art
[0004] At present, in the field of logistics packaging, packaging boxes are widely used. When using packaging boxes to pack products, a layer of cushioning film is usually filled at the bottom of the packaging box to cushion and reduce shock for the products wrapped in the cushioning film.
[0005] In the prior art, the buffer film is usually filled by pressing the buffer film into the packaging box using a fixed structure. Since the area of the buffer film is usually larger than the bottom area of the packaging box, the edge of the buffer film is tilted upward when the buffer film is filled in the packaging box. When the fixed structure needs to be removed after the film filling is completed, the edge of the buffer film is pulled, causing the filled buffer film to be taken out or shifted with the fixed structure, affecting the filling effect of the buffer film and reducing the packaging efficiency. Utility Model Content
[0006] In view of the above problems, the utility model provides a film filling mechanism and packaging equipment. When the film filling is completed, the supporting legs can be driven inward by the cylinder to increase the distance between the supporting legs and the edge of the buffer film, thereby ensuring the filling effect of the buffer film.
[0007] The utility model provides a film filling mechanism, comprising:
[0008] A first supporting plate, with a plurality of first connecting members spaced apart on the periphery thereof;
[0009] A second support plate is located below the first support plate, and a plurality of second connecting members are correspondingly arranged on the outer periphery of the second support plate, and each second connecting member includes an inner ring;
[0010] A plurality of legs, wherein the top of each leg slides through the inner ring and is movably connected to the first support plate through a first connecting member;
[0011] The cylinder is fixed to the first support plate, and the telescopic end of the cylinder extends downward to be fixed to the second support plate. The cylinder drives the telescopic end and the second support plate to move up and down to drive the tilt angle of the support leg to change.
[0012] According to the technical solution, when the cylinder drives the telescopic end to move up and down, it drives the second support plate and the second connecting member fixed to the telescopic end to slide relative to the legs, thereby pulling the legs to shrink inward or expand outward. Specifically, when filling the film, the legs expand outward and can press against the edge of the buffer film. When the film filling is completed, the telescopic end moves downward, the legs shrink inward, and the distance between the legs and the edge of the buffer film is increased, thereby preventing the legs from interfering with the edge of the buffer film when the film filling mechanism is moved upward out of the packaging box, thereby preventing the buffer film from being taken out of the packaging box due to interference, thereby improving the filling effect of the buffer film, and driven by the cylinder, no manual intervention is required, which is conducive to improving the filling efficiency of the buffer film.
[0013] In an optional technical solution of the present invention, the top of each leg is detachably connected to the corresponding first connecting member.
[0014] According to this technical solution, the detachable connection improves the convenience of installation and disassembly, and is conducive to later maintenance and replacement.
[0015] In an optional technical solution of the utility model, a spherical abutment portion is fixed to the bottom of each leg.
[0016] According to this technical solution, the spherical abutment portion can reduce the contact area with the buffer film, prevent the buffer film from sticking to the legs and being taken out of the packaging box or the buffer film from shifting when the film filling is completed, and improve the film filling effect.
[0017] In the optional technical solution of the present utility model, the number of the legs is not less than 3.
[0018] According to the technical solution, multiple legs can be set as needed according to the different shapes or sizes of the buffer film. The number of legs is no less than 3, which improves the stability of the film filling mechanism. The number of legs represents the contact points between the legs and the buffer film. Multiple contact points can ensure the film filling effect.
[0019] In an optional technical solution of the present invention, the second connecting member is telescopically connected to the outer periphery of the second supporting plate.
[0020] According to this technical solution, the distance between the second connecting member and the second supporting plate can be adjusted according to the size of the packaging box or the buffer film, thereby improving the versatility of the film filling mechanism and the film filling effect.
[0021] In an optional technical solution of the utility model, the telescopic end of the cylinder is detachably connected to the second support plate.
[0022] According to the technical solution, the detachable connection is conducive to the installation and removal of the film filling mechanism and facilitates subsequent maintenance.
[0023] The optional technical solutions of the utility model also include:
[0024] A linear bearing is fixed to the second support plate, and the axial direction of the linear bearing is the same as the telescopic direction of the telescopic end;
[0025] The cylindrical shaft is fixed to the bottom of the first supporting plate and cooperates with the linear bearing.
[0026] According to the technical solution, when the telescopic end is extended or retracted, it drives the cylindrical shaft to slide along the linear bearing. Compared with a single telescopic end driving the second support plate to move up and down, the cooperation between the cylindrical shaft and the linear bearing improves the stability of the film filling mechanism and also increases the structural strength of the film filling mechanism.
[0027] In an optional technical solution of the utility model, a mechanism fixing member for fixing the film filling mechanism is fixed on the first support plate.
[0028] According to the technical solution, the mechanism fixing part fixes the film filling mechanism in one position, thereby ensuring the stability and convenience of use during film filling.
[0029] In an optional technical solution of the utility model, the first connecting member is a ball head rod end bearing, and the second connecting member is a fisheye rod end bearing.
[0030] According to the technical solution, the ball head rod end bearing can be fixed to the first support plate and the leg, and can realize the movable connection between the first support plate between the legs. The second connecting piece can be fixed to the second support plate and can realize the movement of the leg in the fisheye rod end bearing.
[0031] The utility model provides a packaging device, comprising the above-mentioned film filling mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a film filling mechanism, which is used to fill a buffer film into the bottom of a packaging box 5. The film filling mechanism includes: a first support plate 1, a second support plate 2, a plurality of legs 3 and a cylinder 4. A plurality of first connecting members 11 are separated and arranged on the outer periphery of the first support plate 1; the second support plate 2 is located below the first support plate 1, and a plurality of second connecting members 21 are correspondingly arranged on the outer periphery of the second support plate 2, and each second connecting member 21 includes an inner ring 211 (preferably, the inner ring 211 is a rotatable structure); the top of each leg 3 slides through the inner ring 211 and is movably connected to the first support plate 1 through the first connecting member 11, the cylinder 4 is fixed to the first support plate 1, and the telescopic end 41 of the cylinder 4 extends downward to be fixed to the second support plate 2, and the cylinder 4 drives the telescopic end 41 and the second support plate 2 to move up and down to drive the inclination angle of the leg 3 to change.
[0041] In the above manner, when the cylinder 4 drives the telescopic end 41 to move up and down (the direction a indicated by 3 in the figure is from bottom to top), the second support plate 2 and the second connecting member 21 fixed to the telescopic end 41 are driven to slide relative to the leg 3, thereby pulling the leg 3 to retract inward (the angle of the leg 3 relative to the telescopic end 41 is reduced) or expand outward (the angle of the leg 3 relative to the telescopic end 41 is increased). Specifically, Figure 4 As shown, when filling the film, the telescopic end 41 moves upward, and the legs 3 expand outward to press against the edge of the buffer film. Figure 5 As shown, when the film filling is completed, the telescopic end 41 moves downward, the support leg 3 contracts inward, and the distance between the support leg 3 and the edge of the buffer film is enlarged, thereby preventing the support leg 3 from interfering with the edge of the buffer film and bringing the buffer film out of the packaging box 5 when the film filling mechanism is moved upward out of the packaging box 5.
[0042] In the preferred embodiment of the present utility model, combined with Figure 2 As shown, the first connecting member 11 is a ball head rod end bearing including a mounting rod 111 and a spherical shell rod 112. The mounting rod 111 is a ball head mounting rod, that is, one end of the mounting rod 111 is spherical, and the spherical end of the mounting rod 111 is rotatably connected to the spherical shell part of the spherical shell rod 112. The rod part of the mounting rod 111 of the ball head rod end bearing is connected to the first support plate 1 through a thread, and the outer surface of the mounting rod 111 is formed with an external thread, and the side of the first support plate 1 extends to the inside of the plate body to form an internal threaded hole. The rod part of the spherical shell rod 112 of the ball head rod bearing is detachably fixed to the top of the leg 3 through a thread. The ball head rod end bearing can be fixed to the first support plate 1 and the leg 3, and can also be connected to the first support plate 1 between the legs 3, and the use effect is better. Moreover, the ball head rod end bearing is detachably connected to the first support plate 1 and the leg 3, which improves the convenience of installation and disassembly, and is conducive to later maintenance and replacement.
[0043] In this embodiment, the first support plate 1 and the second support plate 2 are both rectangular plates, and one corner is cut off from each of the four corners of the rectangular plate for installing the first connecting member 11, which improves the layout rationality and convenience of the film filling mechanism.
[0044] In a preferred embodiment of the utility model, the second connecting member 21 is telescopically connected to the outer periphery of the second support plate 2. Therefore, the distance between the second connecting member 21 and the second support plate 2 can be adjusted according to the size of the packaging box 5 or the buffer film, so as to adapt to the filling of buffer films of different sizes and improve the versatility of the film filling mechanism and the film filling effect.
[0045] In this embodiment, the second connecting member 21 is a fisheye rod end bearing. The fisheye rod end bearing includes a bearing sleeve 213 and a bearing ball (i.e., an inner ring 211, including a spherical body, and a groove for the leg 3 to pass through) rotatably arranged in the bearing sleeve 213, the bearing ball is fixed to the leg 3, the bearing sleeve 213 is fixed with a rod end 212, the rod end 212 is formed with an external thread, the side of the second support plate 2 extends to the inside of the plate body to form an internal thread, the rod end 212 of the fisheye rod end bearing is partially screwed to the inside of the second support plate 2, and the inclination angle of the leg 3 can be adjusted by adjusting the depth of the rod end 212 of the fisheye rod end bearing screwed into the inside of the plate body, thereby adjusting the opening angle of the film filling mechanism, which is suitable for filling buffer films of different sizes, and improves the versatility of the film filling mechanism and the film filling effect. The ball head rod end bearing and the fisheye rod end bearing are both common application forms in this field, and their specific structures are not repeated here, and the structures of the ball head rod end bearing and the fisheye rod end bearing in the prior art can be referred to.
[0046] It should be noted that although the present embodiment illustrates the ball head rod end bearing as a movable connection structure between the top of the leg 3 and the first support plate 3, and the fisheye rod end bearing as a relative sliding connection structure between the leg 3 and the second support plate 2, technicians can choose different structures to achieve the above functions according to actual needs, and the present embodiment does not limit this.
[0047] In this embodiment, the leg 3 is a rod with a circular cross section. In a preferred embodiment of the utility model, the number of the legs 3 is not less than 3. In the above manner, according to the different shapes of the buffer film or the different sizes of the buffer film, multiple legs 3 can be set as needed. The number of legs 3 is not less than 3, which improves the stability of the film filling mechanism. The number of legs 3 represents the contact points between the legs 3 and the buffer film. Multiple contact points can ensure the film filling effect. In addition, the figure formed by the multiple legs 3 is not limited to triangles, rectangles, pentagons, etc. The technicians can adjust the shape formed by the multiple legs 3 according to the shape of the packaging box 5. This embodiment does not limit this. In this embodiment, the number of legs 3 is 4, and the four legs 3 are arranged symmetrically with the extension direction of the cylinder 4 as the axis. The packaging box 5 is usually a rectangular parallelepiped structure. When filling the film, the four legs 3 can press the four corners of the packaging box 5 respectively, and then fill and press the buffer film in the packaging box 5.
[0048] In a preferred embodiment of the utility model, a spherical abutment portion 31 is fixed to the bottom of each leg 3. The spherical abutment portion 31 can reduce the contact area with the buffer film, prevent the buffer film from being brought out of the packaging box 5 or shifting when the film filling mechanism moves upward and out of the packaging box 5 under the drive of the driving mechanism (not shown in the figure) at the end of film filling, thereby improving the film filling effect.
[0049] The structure of the cylinder 4 is a common application form in this field and will not be described in detail. In some embodiments, the cylinder 4 can also be replaced by other linear motion mechanisms that can drive the second support plate 2 to move up and down along the a direction, not limited to the examples given in this embodiment.
[0050] Preferably, the telescopic end 41 is detachably connected to the second support plate 2. The detachable connection is conducive to the installation and removal of the film filling mechanism and is convenient for later maintenance. Specifically, a connecting rod 42 is fixed to the upper surface of the second support plate 2, and the telescopic end 41 is detachably connected to the connecting rod 42, which improves the assembly flexibility of the cylinder 4.
[0051] In the preferred embodiment of the utility model, it also includes: a linear bearing 61 and a cylindrical shaft 62. The linear bearing 61 is fixed to the second support plate 2, and the axial direction of the linear bearing 61 is the same as the telescopic direction of the telescopic end 41; the cylindrical shaft 62 is fixed to the bottom of the first support plate 1 and cooperates with the linear bearing 61. When the telescopic end 41 is extended and retracted, it drives the cylindrical shaft 62 to slide along the linear bearing 61. Compared with the single telescopic end 41 driving the second support plate 2 to move up and down, the cooperation between the cylindrical shaft 62 and the linear bearing 61 improves the stability of the film filling mechanism and increases the structural strength of the film filling mechanism.
[0052] In a preferred embodiment of the utility model, a mechanism fixing member 7 for fixing the film filling mechanism is fixed on the first support plate 1. The mechanism fixing member 7 fixes the film filling mechanism in a position, ensuring the stability and convenience of use during film filling. Specifically, the mechanism fixing member 7 is in the shape of a long straight rod with internal threads, and the mechanism fixing member 7 is fixed to opposite sides of the cylinder 4 to ensure the stability of the film filling mechanism.
[0053] The utility model provides a packaging device, including the above-mentioned film filling mechanism. When the utility model is packaged by the packaging device with the above-mentioned film filling mechanism, at the end of film filling, the cylinder 4 can drive the legs 3 to retract inwards, increase the distance between the legs 3 and the edge of the buffer film, and ensure the filling effect of the buffer film. In addition, there is no need for manual film filling, which improves the film filling efficiency.
[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
