Description

Technical Field

[0001] This utility model belongs to the technical field of paper-plastic molding machine, and in particular relates to a three-mold paper-plastic flipping molding machine. Background Technology

[0002] Paper-plastic products are gradually replacing traditional plastic products due to their environmental friendliness and biodegradability. Paper-plastic molding machines are key equipment in the production of paper-plastic products. Their working principle involves injecting pulp into a mold and then processing it through dehydration, molding, and drying to create the final product.

[0003] Currently, most paper-plastic forming machines on the market use a pulp-scooping structure to scoop the pulp, followed by dewatering, forming, and drying. This pulp-scooping method can lead to pulp stagnation. When pulp stagnation occurs, the quality of the dried product is poor. Furthermore, the pulp-scooping method is not conducive to pulp dewatering, requiring the use of other heating structures for pulp dewatering, which increases energy consumption and affects product quality and yield.

[0029] This embodiment provides a three-mold paper-plastic flipping molding machine, which realizes rapid molding of paper-plastic products. After flipping the pulp suction mold 20, it is beneficial to the rapid dewatering of the pulp, which can effectively avoid the occurrence of pulp stagnation, reduce the energy consumption required in the dewatering process, thereby improving product quality and product yield. Furthermore, the three-mold paper-plastic flipping molding machine of this utility model has a three-mold structure, which is simple in structure and can effectively reduce costs.

[0030] Combination Figures 1 to 6As shown, the three-mold paper-plastic flipping molding machine of this embodiment includes a pulp tank 10, a pulp suction mold 20, a hot pressing screen mold 30, and a hot pressing smoothing mold 40. The pulp tank 10 is filled with pulp. The pulp suction mold 20 can suck up the pulp and form a pulp wet blank. The hot pressing screen mold 30 places the dewatered pulp wet blank, and then the hot pressing smoothing mold 40 hot presses the dewatered pulp wet blank into shape.

[0031] In this embodiment, the three-mold paper-plastic flipping molding machine also includes a frame 50, a pulp tank 10, and a hot pressing screen 30, all of which are fixedly installed on the frame 50. A drive unit 60 is provided on the frame 50. The drive unit 60 drives the pulp suction mold 20 and the hot pressing screen 40 synchronously. The drive unit 60 can drive the pulp suction mold 20 and the hot pressing screen 40 so that the dewatered pulp wet blank can smoothly reach the position of the hot pressing screen 30 and move the hot pressing screen 40 above the hot pressing screen 30 to perform hot pressing molding on the dewatered pulp wet blank.

[0032] Combination Figure 1 , Figure 2 as well as Figure 4 As shown, the suction mold 20 of this embodiment is provided with a suction net 201. After the suction mold 20 enters the pulp tank 10, the pulp is adsorbed by the suction net 201 to form a wet pulp blank on the surface of the suction mold 20. A driver (not shown in the figure) is provided on one side of the suction mold 20. The driver flips the suction mold 20 to dewater the wet pulp blank. The driver in this embodiment is a motor. After the pulp adheres to the surface of the suction mold 20 to form a wet pulp blank, the suction mold 20 is flipped under the driving action of the driver. The flipped suction mold 20 can perform dewatering better and reduce the energy consumption required for heating water evaporation.

[0033] In this embodiment, the suction mold 20 is provided with mounting blocks 70 at both ends. The suction mold 20 is located between the two mounting blocks 70 and rotates relative to the mounting blocks 70. The driver is located inside one of the mounting blocks 70 to drive the suction mold 20 to flip.

[0034] Combination Figure 3 , Figure 5 as well as Figure 6 As shown, in this embodiment, a mesh 31 is provided on the hot pressing mold 30 to place the dewatered pulp preform. The hot pressing die 40 is close to the hot pressing mold 30 to hot press the dewatered pulp preform. The hot pressing die 40 is provided with adsorption holes 401 to adsorb the formed product. After the dewatered pulp preform is placed on the mesh 31, the hot pressing die 40 is moved above the hot pressing mold 30 so that the hot pressing die 40 is close to the hot pressing mold 30 to hot press the pulp preform on the mesh 31. After the hot pressing is completed, the formed product is adsorbed through the adsorption holes 401 on the hot pressing die 40, and the driving unit 60 drives the hot pressing die 40 to remove the formed product.

[0035] In this embodiment, the drive unit 60 includes a drive motor 61, a transmission screw 62, and a motion guide plate 63. The drive motor 61 drives the transmission screw 62, and the motion guide plate 63 cooperates with the transmission screw 62 to move along the length of the transmission screw 62. The hot pressing die 40 is connected to the motion guide plate 63 through a set of guide rods, and the mounting block 70 is connected to the motion guide plate 63 through another set of guide rods. When the drive motor 61 drives the motion guide plate 63 through the transmission screw 62, the pulp suction die 20 and the hot pressing die 40 move synchronously with the motion guide plate 63, thereby driving the wet pulp preform or the formed product to move.

[0036] Furthermore, the motion guide plate 63 is equipped with a first cylinder 80 and a second cylinder 90. The first cylinder 80 drives the suction mold 20, and the second cylinder 90 drives the hot pressing mold 40. The first cylinder 80 can drive the suction mold 20 to enter the pulp tank 10 so as to absorb the pulp, while the second cylinder 90 can drive the hot pressing mold 40 to approach the hot pressing wire mold 30 so as to hot press the wet pulp blank. After the hot pressing is completed, the second cylinder 90 drives the hot pressing mold 40 to approach the formed product, absorb the formed product and then remove it.

[0037] In actual use, the three-mold paper-plastic flipping forming machine of this embodiment pushes the suction mold 20 into the pulp tank 10 by the first cylinder 80. After the pulp is absorbed by the surface of the suction mold 20, the suction mold 20 is reset, so that the pulp forms a wet pulp blank on the surface of the suction mold 20. Then, the driver drives the suction mold 20 to flip. The flipped wet pulp blank is conducive to dewatering. After dewatering is completed, the suction mold 20 is reset, and then the drive unit 60 drives the suction mold 20 to be placed on the hot pressing screen mold 30. After the suction mold 20 releases the negative pressure, the dewatered wet pulp preform is placed on the mesh 31 of the hot pressing mold 30. Then, the drive unit 60 moves the hot pressing mold 40 above the hot pressing mold 30, and the second cylinder 90 drives the hot pressing mold 40 close to the hot pressing mold 30 to hot press the wet pulp preform on the mesh 31. After the product is formed, the formed product is adsorbed through the adsorption hole 401 on the hot pressing mold 40, and the drive unit 60 drives the hot pressing mold 40 to remove the formed product.

[0038] In this embodiment, the suction mold 20 and the hot pressing mold 40 can continuously and repeatedly perform hot pressing molding of the product, effectively improving the hot pressing molding efficiency of the product. This enables rapid molding of paper-plastic products. After the suction mold 20 is flipped, it is beneficial to the rapid dewatering of the pulp, which can effectively avoid the occurrence of pulp stagnation, reduce the energy consumption required in the dewatering process, and thus improve product quality and product yield.
