Description

Technical Field

[0001] This utility model relates to an improved invention of paper container edge rolling equipment, and more particularly to an improved invention of an adsorption type paper container edge rolling and bottom support device, wherein the paper container can be a paper cup or a paper bowl, especially the application of edge rolling and bottom support for rectangular paper bowls. Background Technology

[0002] The paper container edge-rolling support device is used to support the bottom of the paper container so that the edge-rolling die can roll the edges of the paper container. After the edge-rolling is completed, when the edge-rolling die returns to demold, there is a certain friction between the edge-rolling die and the paper container, which can easily cause the paper container to be carried away by the edge-rolling die. In order to prevent the paper container from being carried away by the edge-rolling die after the edge-rolling is completed, an air blowing structure or an elastic pressure plate structure is usually set on the edge-rolling die. The air blowing structure blows air into the inside of the paper container when the edge-rolling die is demolded; the elastic pressure plate structure can keep the bottom of the paper container elastically pressed when the edge-rolling die is demolded, and releases the pressure after demolding is completed. However, both of these methods still result in the paper container being carried away by the edge-rolling die, and the demolding effect is unstable, especially for rectangular paper bowls. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adsorption-type paper container edge rolling and bottom support device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This adsorption-type paper container edge-rolling and bottom-supporting device includes a base and an adjusting seat. The lower center of the base is fixed on the adjusting seat, and the upper end of the base supports and cooperates with the paper container. The feature is that: the base is provided with mounting holes distributed on the left and right, and a suction tube is provided in the mounting holes. The upper end of the suction tube is adsorbed and cooperates with the bottom of the paper container. The lower end of the suction tube is connected to an air pipe connector, the lower end of the air pipe connector extends out of the base, and the air pipe connector is fixedly connected to the base.

[0005] The base includes a tray and a cover plate. The cover plate is fixed on the tray, the tray is supported and matched with the lower end of the paper container, and the cover plate matches the bottom cavity of the paper container.

[0006] The lower end of the base is provided with a transition plate, and the air pipe connector is fixed to the transition plate.

[0007] The transition plate has small holes, into which the air pipe connector is inserted and locked by a nut.

[0008] The base is provided with several symmetrically distributed weight-reducing holes.

[0009] The beneficial effect of this utility model is that the improved adsorption-type paper container edge-rolling support device, by setting adsorption structures such as suction skin and air pipe connector on the bottom support, can adsorb the paper container on the bottom support, effectively preventing the paper container from being taken away by the edge-rolling mold after the edge-rolling process is completed.

[0010] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] Figure 2 This is a cross-sectional view of the structure of this utility model.

[0013] Figure 3 This is an exploded view of the base of this utility model. Detailed Implementation

[0014] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-2 The adsorption-type paper container edge-rolling and bottom-supporting device includes a base 1 and an adjusting seat 2. The lower center of the base 1 is fixed on the adjusting seat 2, and the upper end of the base 1 supports and cooperates with the paper container 9. The base 1 is provided with mounting holes 3 distributed on the left and right. A suction skin 4 is installed in the mounting holes 3. The upper end of the suction skin 4 is adsorbed and cooperates with the bottom of the paper container 9. The lower end of the suction skin 4 is connected to an air pipe connector 5. The lower end of the air pipe connector 5 extends out of the base 1 for connection to a negative pressure source, and the air pipe connector 5 is fixedly connected to the base 1.

[0015] The working principle of this utility model is as follows: the paper container 9 is sent to the edge-rolling station by the conveying mechanism and accurately placed on the upper surface of the base 1. The air pipe connector 5 is connected to the negative pressure source through the air pipe. The negative pressure is transmitted to the internal cavity of the suction skin 4 through the air pipe connector 5. The suction skin 4 generates an adsorption force under the action of negative pressure, thereby firmly adsorbing the bottom of the paper container 9. After the edge rolling is completed, the mold begins to rise and detach from the paper container 9. The adsorption force of the suction skin 4 on the paper container 9 is greater than the force of the mold, and the paper container 9 is stably retained on the base 1.

[0016] For a further improved implementation method, see Appendix Figure 3 The base support 1 includes a disc body 11 and a cover plate 12. The cover plate 12 is fixed to the disc body 11, and the disc body 11 supports the lower end of the paper container 9. The cover plate 12 matches the bottom cavity of the paper container 9, that is, the cover plate 12 is embedded in the bottom cavity of the paper container 9 to form a support. The base support 1 is assembled from the disc body 11 and the cover plate 12, adopting a split design, which facilitates precision machining and assembly. Moreover, the shape of the cover plate 12 can be customized according to the bottom cavity structure of different models of paper containers 9, realizing rapid changeover and enhancing equipment compatibility.

[0017] For a further improved implementation method, see Appendix Figure 2The lower end of the base 1 is provided with a transition plate 6, and the air pipe connector 5 is fixed on the transition plate 6. Preferably, the transition plate 6 is provided with a small hole, the air pipe connector 5 is inserted into the small hole and locked by a nut 7, so as to realize the quick and stable connection of the air pipe connector 5.

[0018] For a further improved implementation method, see Appendix Figure 1 The base 1 is provided with a number of symmetrically distributed weight-reducing holes 8, preferably four, which are symmetrically distributed in pairs in front of and behind the mounting holes 3, which can effectively reduce the shaking problem caused by excessive weight.

[0019] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
