Description

Technical Field

[0001] This utility model relates to the field of paper tableware manufacturing technology, specifically to a paper tableware forming machine. Background Technology

[0002] As the level of social economy continues to improve, people's material life is becoming richer and richer. In order to adapt to the fast-paced life, more and more people or restaurants are starting to use paper tableware. Compared with the porcelain and glass tableware of the past, paper tableware is simple to use and does not need to be washed after use. After special treatment, some paper tableware can also be recycled and reused. Paper cups are one type of paper tableware.

[0003] The production process of paper tableware typically includes pulping, dewatering and forming, hot pressing and shaping, edge trimming, and sterilization. Dewatering and forming involves dewatering the pulp from the pulping process on a forming mold to create a preliminary tableware shape with a higher water content. The working principle is as follows: pulp is scooped from a pulp tank into the forming mold, which contains a wire mesh. A vacuum pump connected to the forming mold creates a vacuum, causing the pulp to adhere to the wire mesh and form the preliminary tableware shape. Existing forming machines have the following technical problems:

[0004] 1. The method used is to control the vacuuming time. The longer the vacuuming time, the more slurry adheres to the wire mesh, and the thicker the formed tableware is, making it difficult to control the thickness of the tableware.

[0005] 2. After the slurry adheres to the outside of the wire mesh, it needs to be dried to shape the tableware before it can be discharged. The vacuum environment affects the evaporation and discharge of moisture, thus affecting the drying efficiency of the tableware.

[0006] To address the aforementioned technical problems, this application proposes a paper tableware forming machine. Utility Model Content

[0031] Example 1

[0032] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a paper tableware forming machine includes a base 1. Multiple sets of mold positioning grooves 2 are provided on the upper side of the base 1. Mold components are installed inside the mold positioning grooves 2. The mold components include an outer mold 3 and an inner mold 7. The outer mold 3 of all shapes of paper tableware has the same outer shape and size. The outer mold 3 is inserted into the inner side of the mold positioning groove 2, and the inner mold 7 is inserted into the inner side of the outer mold 3. Limiting strips 4 are installed on the outer wall of the outer mold 3. Limiting slots 5 are provided on the side wall of the mold positioning groove 2. The limiting strips 4 are inserted into the corresponding limiting slots 5 to position the outer mold 3. A hand-tightening bolt 21 passes through the bottom of the mold positioning groove 2. The top of the hand-tightening bolt 21 passes through to the inner bottom of the outer mold 3 and is connected by threads to position the outer mold 3.

[0033] As attached Figure 1 and attached Figure 4 As shown, a height adjustment assembly is connected between the bottoms of multiple sets of inner molds 7 to drive the inner molds 7 to move up and down. The height adjustment assembly includes multiple sets of connecting rods 11 and a horizontal plate 12. One end of the connecting rod 11 is fixedly installed to the bottom of the inner mold 7 by a thread, and the other end is fixedly connected to the lower side of the horizontal plate 12. The inner molds 7 are easy to disassemble and replace. A hydraulic telescopic rod 13 is fixedly connected to the upper side of the horizontal plate 12. The hydraulic telescopic rod 13 is installed on the frame. The extension and retraction of the hydraulic telescopic rod 13 drives the multiple sets of inner molds 7 to move up and down inside the outer mold 3, which facilitates the adjustment of the position of the inner molds 7 and the discharge of paper tableware.

[0034] As attached Figure 1 and attached Figure 2 As shown, at least one set of slurry tanks 14 are fixedly installed on the upper side of the horizontal plate 12. The slurry tanks 14 have built-in stirring components to prevent the slurry inside the slurry tanks 14 from settling and affecting the slurry discharge. A slurry discharge pipe 15 is installed at the bottom of the slurry tanks 14. A cover plate 8 is installed on the upper outer side of the inner mold 7. The cover plate 8 contacts the upper side of the outer mold 3. At this time, the position between the inner mold 7 and the outer mold 3 is determined. The space between the inner mold 7 and the outer mold 3 is the thickness of the paper lunch box. The cover plate 8 is attached to the upper side of the mold positioning groove 2 and multiple sets of slurry inlet pipes 9 are installed. The slurry inlet pipes 9 discharge... The slurry end is located between the outer mold 3 and the inner mold 7. The slurry discharge pipe 15 is connected to multiple sets of slurry inlet pipes 9 through a multi-port pipe. A control valve is installed on the slurry discharge pipe 15. When the control valve is opened, the slurry is sent to the space between the outer mold 3 and the inner mold 7 through the slurry discharge pipe 15. An outwardly expanding slope 10 is provided at the top edge of the side wall of the outer mold 3 to widen the space between the top of the side wall of the outer mold 3 and the inner mold 7, which facilitates the feeding of material from the slurry inlet pipe 9 to the space between the outer mold 3 and the inner mold 7. It also makes the slurry flow faster inside the outwardly expanding slope 10, which can disperse the material and improve the uniformity of the slurry distribution.

[0035] As attached Figure 4 and attached Figure 5 As shown, the inner mold 7 has multiple sets of sieve holes on its side wall, with a hole diameter of 0.3 to 0.6 mm. Water in the slurry is drained through the multiple sets of sieve holes to the space between the outer mold 3 and the inner mold 7, causing the slurry to accumulate between the outer mold 3 and the inner mold 7. A water suction pipe 16 is installed inside the inner mold 7. A positioning block 17 is installed on the upper inner side of the inner mold 7. The water suction pipe 16 passes through the positioning block 17 and is positioned by the positioning block 17. A drainage assembly is connected between the multiple sets of water suction pipes 16. The drainage assembly includes a connecting pipe 18 and a pump body 19. The connecting pipe 18 is connected to the multiple sets of water suction pipes 16, and one end is connected to the water inlet of the pump body 19. Water inside the inner mold 7 is discharged through the pump body 19, the connecting pipe 18, and the multiple sets of water suction pipes 16. A drain pipe 20 is connected to the drain end of the pump body 19, and the water is discharged into a collection bucket through the drain pipe 20.

[0036] As attached Figure 3 and attached Figure 5 As shown, a heating block 6 is installed on the inner side of the mold positioning groove 2. Both the outer mold 3 and the inner mold 7 are made of heat-conducting metal. The limiting slot 5 is close to the heating block 6. The heating block 6 generates heat through internal resistance, which can control the heating temperature. The heating block 6 heats the side wall of the mold positioning groove 2, and the temperature is transferred to the outer mold 3 to dry the formed paper lunch box. The inner mold 7 then conducts heat, and the evaporated moisture is evenly discharged through multiple sets of sieve holes on the inner mold 7. The limiting strip 4 is made of heat-conducting metal. The limiting slot 5 is close to the heating block 6. The limiting strip 4 increases the heat exchange area between the outer mold 3 and the side wall of the mold positioning groove 2, which can improve the heat conduction effect.
