Description

Technical Field

[0001] This utility model relates to the field of packaging automation technology, and in particular to an automatic film pressing device. Background Technology

[0002] During the production and packaging of adhesives, the adhesive needs to be filled into buckets and then sealed to reduce the reaction between the adhesive and the outside air, preventing the adhesive from oxidizing or losing moisture. However, a small amount of air usually remains in the bucket and cannot be completely removed. This air will react with the adhesive, reducing the adhesive's shelf life and effectiveness. Therefore, before sealing the container, a plastic film needs to be laid on the surface of the adhesive in the bucket to isolate the adhesive from the air inside the container.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0024] See Figure 1 This utility model provides an automatic film pressing device, including a frame 2, a film storage mechanism 4, a film pressing mechanism 3, and a motion mechanism 1.

[0025] One side of frame 2 has a storage mechanism mounting space, within which the film storage mechanism 4 is installed. The film storage mechanism 4 is a prior art structure, a component used in adhesive packaging production lines for storing plastic film, and will not be described in detail here. The other side of frame 2 has a glue bucket placement space. Frame 2 also has a motion mechanism mounting beam 201, on which the motion mechanism 1 is mounted. Additionally, adjustable feet 202 may be provided at the bottom of frame 2.

[0026] See Figure 1 and Figure 2 The motion mechanism 1 includes: a horizontal guide rail slide 101, a vertical guide rail slide 102, and a fixed base 103.

[0027] Both the horizontal guide slide 101 and the vertical guide slide 102 are commercially available electric guide slide modules. The horizontal guide slide 101 is mounted and fixed on the frame 2. The slide portion of the vertical guide slide 102 is connected and fixed to the slide portion of the horizontal guide slide 101. The fixed base 103 is connected and fixed to the guide rail portion of the vertical guide slide 102. When the slide portion of the horizontal guide slide 101 slides along the horizontal guide rail portion, it will drive the entire vertical guide slide 102 to move horizontally. The slide portion of the vertical guide slide 102 and its guide rail portion can slide relative to each other in the vertical direction, thereby driving the fixed base 103 to move vertically. Through the action of the horizontal guide slide 101 and the vertical guide slide 102, the horizontal and vertical movement of the fixed base 103 can be achieved.

[0028] See Figure 2 The fixed base 103 has a vertical plate 103a, a reinforcing plate 103b, and a horizontal plate 103c. The vertical plate 103a is used to fix the guide rail portion of the vertical guide rail slide 102. The horizontal plate 103c is used to connect to the film pressing mechanism 3. The two sides of the reinforcing plate 103b are respectively connected and fixed to the vertical plate 103a and the horizontal plate 103c, which strengthens and stabilizes the overall structure of the fixed base.

[0029] See Figure 1 and Figure 2 The film pressing mechanism 3 is connected below the fixed base 103 of the motion mechanism 1, and the entire film pressing mechanism 3 is driven by the motion mechanism 1 to move horizontally and vertically. (See reference...) Figures 2 to 5 The film pressing mechanism 3 includes a top plate 5, a bottom plate 12, a cylinder 15, a film taking assembly, a film installation unit, and a guide assembly.

[0030] See Figure 5 The cylinder body of cylinder 15 is fixed to the upper surface of base plate 12, located at the center of base plate 12. The piston rod of cylinder 15 extends upward, and the upper end of the piston rod is bolted to the center of top plate 5.

[0031] The film-grabbing assembly is used to pick up plastic film. Several sets of film-grabbing assemblies are distributed on the base plate 12. The film-grabbing assembly includes a suction cup fitting 14 and a suction cup 11. The suction cup fitting 14 is mounted on the base plate 12, and the suction cup 11 is mounted on the suction cup fitting 14. The suction cup 11 is located below the base plate 12.

[0032] The film mounting unit is used to detach the plastic film from the suction cup. The film mounting unit includes a pressing structure 9, a guide rail slider assembly, and a limit block assembly.

[0033] The edge-pressing structure 9 consists of multiple sets; in this embodiment, four sets are used, but this is not a limitation. In other embodiments, the edge-pressing structure 9 can be of other quantities. The number of guide rail slider assemblies is the same as the number of edge-pressing structures 9. The number of limiting block assemblies is the same as the number of edge-pressing structures 9.

[0034] The guide rail and slider assembly includes a guide rail 7 fixed to the lower surface of the top plate 5, and a slider 8 fitted onto the guide rail 7. The four sets of guide rail and slider assemblies are arranged in a circular array, with the center of the circular array being the location of the piston rod, and the guide rail 7 being arranged along the radial direction of the circular array.

[0035] The limiting block assembly includes a connecting block 13 fixed to the upper surface of the base plate 12, and a limiting block 10 is fixed on the connecting block 13. The four sets of limiting block assemblies are positioned to cooperate with the pressing edge structure 9.

[0036] See Figure 5 The pressing structure 9 includes a plate portion with an obliquely oriented limiting sliding hole 9a. Support rod portions 9c are connected to the left and right sides of the plate portion, and the pressing portion 9b is connected to both the plate portion and the support rod portions 9c.

[0037] Preferably, the plate portion, support rod portion 9c, and pressing edge portion 9b are integrated into a single structure. Depending on the type of material used, the integrated structure can be achieved by methods such as metal welding or plastic molding.

[0038] The pressing edge structure 9 is slidably connected to the top plate 5 through the guide rail slider assembly. Specifically, the plate part of the pressing edge structure 9 is connected and fixed to the slider 8, the slider 8 is slidably connected to the guide rail 7, and the guide rail 7 is fixed on the top plate 5. Therefore, the pressing edge structure 9 and the top plate 5 form a sliding connection.

[0039] The pressing structure 9 is slidably connected to the base plate 12 through the limiting block assembly. Specifically, each limiting block 10 is located in a limiting sliding hole 9a of a pressing structure 9. When the piston rod of the cylinder 15 extends or retracts, it will drive the top plate 5 away from or closer to the base plate 15, and drive the slider 8 to slide along the guide rail 7, thereby driving the pressing structure 9 to slide relative to the limiting block 10 through the limiting sliding hole 9a. Since the limiting block 10 is fixed to the base plate through the connecting block 13, the pressing structure 9 and the base plate 12 form a sliding connection.

[0040] Furthermore, the base plate 12 is disc-shaped, and the pressing part 9b of the pressing structure 9 is an arc segment structure. All the pressing parts 9b of the pressing structures 9 together form a ring structure, which is located on the outer side of the circumference of the base plate 12.

[0041] The guide components are in multiple sets; in this embodiment, four sets are provided. The guide components are used to limit the horizontal movement of the base plate surface.

[0042] Each guide assembly includes a guide shaft 6 and a linear bearing 16. The linear bearing 16 is mounted and fixed on the top plate 5. The lower end of the guide shaft 6 is fixed to the upper surface of the base plate 12. The upper end of the guide shaft 6 is inserted into the linear bearing 16, extends out of the top plate 5, and is bolted and fixed to the horizontal plate 103c of the fixing seat.

[0043] In this embodiment, for the connection methods of the above-mentioned components not described, conventional installation methods such as bolt connection, welding, and plug-in are used, and will not be described in detail here.

[0044] The automatic film pressing device in this embodiment operates as follows:

[0045] 1) The glue buckets are conveyed by a conveyor belt to the glue bucket placement space of frame 2.

[0046] 2) Automatic film pressing device for mold removal: The piston rod of the operating cylinder 15 extends. Then, the operating motion mechanism 1 drives the film pressing mechanism 3 to descend vertically to the film storage mechanism 4, so that the suction cup 11 contacts the plastic film. Since the plastic film is light in weight, it will be adsorbed onto the suction cup 11 through electrostatic adsorption and slight air pressure difference adsorption.

[0047] 3) Automatic film pressing device for film installation: The operating motion mechanism 1 moves the film pressing mechanism 3 horizontally above the glue tank. The operating motion mechanism 1 then moves the film pressing mechanism 3 down to the required pressing position inside the tank. Afterwards, the piston rod of the operating cylinder 15 retracts, causing the top plate 5 to descend, which in turn moves the pressing edge structure 9. This causes the annular structure formed by the pressing edge part 9b to move downwards, pressing the plastic film and separating it from the suction cup 11. Simultaneously, due to the greater adhesion between the plastic film and the glue, the plastic film will detach from the suction cup 11 and cover the glue.

[0048] 4) After that, the operating motion mechanism 1 drives the pressing mechanism 3 back to its original position to complete the pressing work.

[0049] 5) The glue bucket continues to be transported by the conveyor belt. Then, the next glue bucket is transported, and the above steps are repeated to complete the next lamination work.

[0050] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
