Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic cup lid production, in particular to a dehumidifying mold for paper-plastic cup lid production. Background Technique

[0002] A paper-plastic cup lid is an environmentally friendly cup lid, usually made of a mixture of paper and plastic materials. This material combination aims to reduce the impact on the environment by replacing traditional all-plastic or foam cup lids to reduce plastic consumption and environmental pollution. Paper-plastic cup lids are generally formed by pressing with a mold during production. However, during the production process of paper-plastic materials, moisture will remain. If dehumidification is not carried out and they are directly encapsulated and used, the moisture they carry will be absorbed by the paper cup, which will affect the paper cup. Currently, generally, after the production and pressing of paper-plastic cup lids are completed, they are then removed and dehumidified. This method is inconvenient, and the mold is generally installed and fixed with bolts during use. When it is necessary to remove it and replace the mold for cup lids of different sizes later, the operation is rather troublesome. Therefore, we propose a dehumidifying mold for paper-plastic cup lid production to solve the above problems. Content of the Utility Model

Specific implementation manner

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment

[0023] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, a dehumidification mold for the production of paper-plastic cup lids proposed in an embodiment of the present utility model includes a bottom plate 1. In some embodiments, an installation frame 13 is fixed to the bottom of the bottom plate 1. Three installation holes 14 are provided on both sides of the bottom of the installation frame 13. When the entire mold is installed and fixed, it will be more convenient to operate. The top of the bottom plate 1 is fixed with a top plate 2 through four support rods. Two hydraulic cylinders 1 3 are fixed to the top of the top plate 2. The ejecting ends of the two hydraulic cylinders 1 3 slide through the top plate 2 and extend to its lower side and are fixed with a moving plate 4. Limiting seats 5 are fixed inside the installation grooves provided on the moving plate 4 and the bottom plate 1. Limiting frames 6 are sleeved on the limiting seats 5. A hollow lower mold base 7 is fixed to the top of the lower limiting frame 6, and a hollow upper mold base 8 is fixed to the bottom of the upper limiting frame 6. V-shaped flow deflectors 15 are equidistantly fixed inside the hollow lower mold base 7 and the hollow upper mold base 8, which can extend the flow time of the heat medium inside the two, so as to make the hollow lower mold base 7 and the hollow upper mold base 8 heated more thoroughly. An inlet pipe 9 and an outlet pipe 10 are connected and fixed to both the hollow lower mold base 7 and the hollow upper mold base 8. Limiting grooves 11 are provided on all four sides of the two limiting frames 6. Limiting components 12 for engaging with the limiting grooves 11 are provided inside the limiting seats 5. A square through-hole 17 for making way for the upper limiting component 12 is provided on the top of the top plate 2, which plays a role of making way to avoid interference between the upper limiting component 12 and the top plate 2 when it moves. During the process of using this paper-plastic cup lid production mold, after it is installed in a suitable position, the pipes for the inlet and outlet of the heat medium can be connected and fixed to the inlet pipe 9 and the outlet pipe 10 of the hollow lower mold base 7 and the hollow upper mold base 8. At this time, the heat medium will circulate inside the two and heat them. The heat medium used can be heating oil or hot water, which is not limited here. Subsequently, the paper-plastic product to be formed can be placed inside the mold cavity of the hollow lower mold base 7. Start the two hydraulic cylinders 1 3 to drive the moving plate 4 to move downward. After the moving plate 4 moves downward, it will drive the upper limiting seat 5 to move downward. Finally, after the limiting seat 5 moves downward, it will drive the hollow upper mold base 8 to fit with the hollow lower mold base 7. At this time, the forming work of the paper-plastic cup lid can be completed. When the hollow lower mold base 7 and the hollow upper mold base 8 need to be removed and replaced later, the hollow upper mold base 8 can be moved downward to fit with the hollow lower mold base 7, and then operate the two groups of limiting components 12 to release the limit on the limiting frame 6 respectively. Then the two can be removed and replaced.

[0024] As Figure 1 and Figure 2As shown, in some embodiments, the limiting component 12 includes a second hydraulic cylinder 1201 fixed to the bottom of the limiting seat 5. The ejecting end of the second hydraulic cylinder 1201 slidably penetrates through the limiting seat 5 and extends into its interior and is fixed with a pushing block 1202. Four through openings formed on the four sides of the limiting seat 5 are each slidably connected with a limiting block 1203 adapted to the limiting groove 11 and the pushing block 1202. The bottoms of the limiting blocks 1203 are each in contact with the top of the pushing block 1202. One ends of the four limiting blocks 1203 are respectively inserted into the corresponding limiting grooves 11. Two springs 1204 are fixed to one side wall of each limiting block 1203, and the other ends of the springs 1204 are fixed to the inner wall of the limiting seat 5. When the whole mold needs to be replaced, start the contraction of the ejecting end of the second hydraulic cylinder 1201. After the ejecting end of the second hydraulic cylinder 1201 contracts, it will drive the pushing block 1202 to reset. After the pushing block 1202 moves, the restriction on the limiting block 1203 will be released. At this time, under the restoring force of the spring 1204, the limiting block 1203 can be driven to reset and separated from the limiting groove 11. After the restriction on the limiting frame 6 is released, the hollow upper mold base 8 can be moved downward to be removed together with the hollow lower mold base 7. During installation, after the limiting frame 6 is clamped with the limiting seat 5, start the extension of the ejecting end of the second hydraulic cylinder 1201, and the pushing block 1202 can be used to push the limiting block 1203 to move. After the limiting block 1203 moves, it will be re-inserted into the limiting groove 11, and then the installation and fixation of the mold can be realized.

[0025] As Figure 1 shown, in some embodiments, four guide rods 16 adapted to the hollow upper mold base 8 are fixed to the top of the hollow lower mold base 7. The hollow upper mold base 8 slides on the surfaces of the four guide rods 16, which can enhance the stability of the two during forming and fitting, and when the two are removed for replacement, it is convenient to disassemble and place them together.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
