Description

Technical Field

[0001] This utility model relates to the field of paper and plastic product processing technology, and in particular to a single-cylinder dual-station forward and backward shifting forming device for paper and plastic products. Background Technology

[0002] Paper-plastic products are manufactured through pulp molding, a three-dimensional papermaking technology that uses waste paper as raw material and shapes paper products into specific forms using special molds on a molding machine. In addition to making lunch boxes and tableware, it can also be used to make industrial cushioning packaging.

[0003] Existing paper-plastic product molding equipment mostly has only a single processing station when producing paper-plastic products. Therefore, after completing the molding process of a paper-plastic product, the paper-plastic product must be removed from the lower mold forming groove before the next molding operation can be carried out. The production efficiency is relatively low and the effect is not ideal.

[0004] Therefore, it is necessary to invent a single-cylinder, dual-station forward and backward shifting molding device for paper-plastic products to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a single-cylinder, dual-station forward and backward shifting molding device for paper-plastic products. This device allows for the simultaneous removal of the paper-plastic product and the addition of the next batch of raw materials during the paper-plastic molding process, thereby shortening the time interval between adjacent molding operations and effectively improving production efficiency. The actual performance is more ideal, thus solving the problem mentioned in the background art where existing paper-plastic product molding equipment mostly has only a single processing station. Therefore, after completing one molding operation, the paper-plastic product must be removed from the lower mold forming groove before the next molding operation can proceed, resulting in relatively low production efficiency and unsatisfactory performance.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a single-cylinder, dual-station forward and backward shifting forming device for paper-plastic products, comprising:

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a single-cylinder, dual-station forward and backward shifting molding apparatus for paper-plastic products according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the feeding and forming mechanism 1 of a single-cylinder, dual-station forward and backward shifting forming device for paper-plastic products according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the front-to-back dual-station assembly 2 and the ejection assembly 3 of a single-cylinder dual-station front-to-back moving molding apparatus for paper and plastic products according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the single-cylinder dual-station forward and backward shifting molding device for paper and plastic products disclosed herein may include: a feeding molding mechanism 1, a forward and backward shifting dual-station assembly 2, and two sets of ejection assemblies 3, etc.

[0030] like Figure 2 As shown in this disclosure, the feeding and forming mechanism 1 includes a support platform 11, a support base 12 is fixedly installed at the bottom of the support platform 11, a fixed frame 13 is fixedly installed at the top of the support platform 11, a feeding pipe 14 is fixedly installed through the front and rear sides of the top of the fixed frame 13, an electric push rod A15 is fixedly installed at the center of the top of the support platform 11, the output shaft of the electric push rod A15 slides through the top of the fixed frame 13 and extends to the inside of the fixed frame 13 and is fixedly connected to the upper template 16.

[0031] Therefore, the material can be supplied to the adjacent lower template 23 by the material supply pipe 14, and the upper template 16 can be moved down by the electric push rod A15 so that the upper template 16 enters the inner side of the adjacent lower template 23, and then cooperates with the lower template 23 to form the paper-plastic raw material.

[0032] It should be noted that a raw material pump is installed on the feed pipe 14. The input ends of the two raw material pumps and the electric push rod A15 are all connected to a control system. The control system is used to control the opening and closing of the two raw material pumps and the electric push rod A15. This is prior art and will not be described in detail here.

[0033] like Figure 3 As shown, in a preferred embodiment, the forward and backward dual-station assembly 2 includes an electric push rod B21 fixedly disposed on the rear side of the fixed frame 13. The output shaft of the electric push rod B21 passes through the outer wall of the fixed frame 13 and slides to the inner side of the fixed frame 13. The movable base 22 is slidably disposed on the bottom of the support platform 11 and its rear end is fixedly connected to the output shaft of the electric push rod B21. Two lower templates 23 are fixedly disposed on the top of the movable base 22, and two limiting grooves 24 are opened on the right side of the movable base 22.

[0034] This allows the paper-plastic material to be fed into the top forming groove of the lower front mold plate 23 via the front feeding pipe 14. Then, the electric push rod B21 moves the movable base 22 backward. At this time, the lower front mold plate 23 moves below the upper mold plate 16, and the lower rear mold plate 23 moves below the rear feeding pipe 14. The electric push rod A15 lowers the upper mold plate 16, while the rear feeding pipe 14 feeds the paper-plastic material into the top forming groove of the lower rear mold plate 23. This allows the upper mold plate 16 to work in conjunction with the lower front mold plate 23 to form the paper-plastic product while simultaneously completing the lower rear mold plate 23. The addition of paper-plastic material to the top forming groove of the lower template 23, and the addition of paper-plastic material to the upper template 16 when the electric push rod A15 drives the upper template 16 to descend, if there is a paper-plastic product in the top forming groove of the lower template 23, the paper-plastic product is first removed by the ejector component 3 before the feeding pipe 14 adds paper-plastic material. Compared with the prior art, the removal of paper-plastic product and the addition of paper-plastic material can be carried out simultaneously during the paper-plastic molding process, thereby shortening the time interval between two adjacent paper-plastic molding operations, effectively improving production efficiency, and the actual use effect is more ideal.

[0035] like Figure 3 As shown in this disclosure, any set of ejection components 3 includes a receiving groove 31 opened inside the lower template 23, an ejection plate 32 is provided inside the receiving groove 31, a sealing ring is fixedly nested on the outside of the ejection plate 32, the bottom of the lower template 23 is slidably disposed through the ejection slide rod 33 in the vertical direction, the top of the ejection slide rod 33 is fixedly connected to the bottom of the ejection plate 32, and a lever plate 34 is fixedly disposed at the bottom of the ejection slide rod 33 and slidably disposed inside the adjacent limiting slide groove 24 in the vertical direction.

[0036] Therefore, after the paper-plastic product is formed and removed from below the upper template 16, the relevant personnel standing on the right side of the device manually move the corresponding lever 34 upward. The lever 34 moves the ejector slide rod 33 and the ejector plate 32 upward along the limiting slide groove 24. When the ejector plate 32 moves upward, it moves out from the inside of the receiving groove 31. At the same time, the paper-plastic product formed inside the forming groove of the lower template 23 is pushed out, which makes it easier for the personnel to remove the paper-plastic product. After the paper-plastic product is removed, the lever 34 is pressed down until the ejector plate 32 enters the inside of the receiving groove 31 again. At this time, the sealing ring on the outside of the ejector plate 32 seals the gap between the ejector plate 32 and the receiving groove 31 to prevent the paper-plastic material from flowing out through the gap.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
