Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0026] A convex dot paper-plastic box mold with an air blowing and stripping function according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.
[0027] Example 1
[0028] For easier understanding, see Figures 1 to 6 The utility model provides an embodiment of a convex dot paper-plastic box mold with a blowing and stripping function, comprising an upper mold 1 and a lower mold 2, an air outlet 3 is opened on the top of the lower mold 2, and a blocking mechanism is provided at one end of the air outlet 3;
[0029] The blocking mechanism includes an installation shaft 5, a first baffle 6, a connecting rod 7, a guide rail 8 and a second baffle 9. A movable groove 10 is opened on the inner wall of one end of the air outlet 3. The installation shaft 5 is installed on the inner wall of the movable groove 10. The first baffle 6 is fixedly installed on the side wall of the installation shaft 5. The guide rail 8 is fixedly installed on the inner wall of the movable groove 10. The second baffle 9 is slidably connected to the side wall of the guide rail 8. The first baffle 6 and the second baffle 9 are movably connected through the connecting rod 7.
[0030] It should be noted that by setting the installation shaft 5, the first baffle 6 can be driven to rotate inside the air outlet 3, and by setting the guide rail 8, the moving direction of the second baffle 9 can be limited. By setting the connecting rod 7, the first baffle 6 can push the second baffle 9 to slide along the side wall of the guide rail 8 when rotating. By setting the second baffle 9, the top of the air outlet 3 can be blocked to prevent the pulp from flowing into the air outlet 3 during the molding process in the mold, thereby reducing defects and achieving better use effect.
[0031] In some embodiments, Figure 4 As shown, the mounting shaft 5 is rotatably connected to the inner wall of the movable groove 10 through a torsion spring, one end of the connecting rod 7 is rotatably connected to the bottom of one end of the second baffle 9, and the other end of the connecting rod 7 is rotatably connected to the top of one end of the first baffle 6.
[0032] It should be noted that, by providing a torsion spring, the installation shaft 5 can be driven to rotate to one side, driving the first baffle plate 6 to rotate to one side, and by providing a connecting rod 7, the second baffle plate 9 can be pushed to slide when the first baffle plate 6 rotates.
[0033] In some embodiments, Figure 3 As shown, a gas delivery hole 4 is opened at the bottom of the lower mold 2, and the gas delivery hole 4 is connected to the gas outlet 3.
[0034] It should be noted that the gas delivery holes 4 can be used to deliver gas to blow out the convex dot paper-plastic box after forming.
[0035] Example 2
[0036] In some embodiments, Figure 5 As shown, a supplementary mechanism is arranged on the top of the second baffle 9, and the supplementary mechanism includes a spring 12 and a protrusion 13. An installation cavity 11 is opened on the top of the second baffle 9, and the spring 12 is fixedly installed on the inner wall of the installation cavity 11. The protrusion 13 is fixedly installed on one end of the spring 12. A circular chamfer is opened on one end of the top of the protrusion 13. A roller 14 is rotatably connected to the top of the protrusion 13, and the roller 14 is located at the circular chamfer at one end of the top of the protrusion 13.
[0037] It should be noted that by setting the protrusion 13, the top of the air outlet 3 can be better blocked, by setting the spring 12, the protrusion 13 can be pushed upward, by setting the circular chamfer, the protrusion 13 can be squeezed into the installation cavity 11 when the second baffle 9 slides, and by setting the roller 14, the protrusion 13 can be squeezed in more smoothly.
[0038] Working principle: When in use, the upper mold 1 and the lower mold 2 are closed, and the pulp is injected into the mold. The top of the air outlet 3 can be blocked by the second baffle 9 and the raised piece 13 on the top of the second baffle 9 to prevent the pulp from flowing into the air outlet 3 during the molding process in the mold. When inflation and demoulding are required, gas is input from the gas supply hole 4. The air inside the air outlet 3 is blown upward from the bottom. The flowing gas drives the first baffle 6 to rotate to one side along the mounting shaft 5. Through the connecting rod 7, the first baffle 6 can push the second baffle 9 to slide along the side wall of the guide rail 8 when rotating, so that the air outlet 3 is connected to the outside, and the gas can be blown into the mold to demould the formed convex paper-plastic box.
[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
