Description

Technical Field

[0001] The utility model relates to the technical field of paper pulp molding, in particular to a paper pulp tableware turning and molding device. Background Art

[0002] During the working process of the pulp tableware flipping and forming device, the forming lower mold first flips and enters the pulp tank to stick the material, and then flips and resets after the sticking is completed to close the mold with the forming upper mold to press and form the product. The working process is controlled by the flipping and slurry suction mechanism. However, there are certain disadvantages in the use of the device in the prior art. For example, the publication number CN217973841U records a pulp tableware flipping and forming device, including a pulp pool, support plates are connected to both sides of the pulp pool, a bearing seat is connected to the top of the support plate, a second shaft rod is connected inside the bearing seat, one end of the second shaft rod is connected to a side plate, a first motor is connected to the top of the front support plate, and a gear is connected to one end of the first motor;

[0003] Although the above device prevents the pulp from easily falling off the steel mesh on the surface of the pulp containing tank, resulting in poor molding effect, the excess pulp will also affect the molding of the tableware. The above device cannot discharge the excess pulp, and the flipping is performed by two gears in conjunction with the motor, resulting in poor flipping accuracy and inconvenience in later mold closing.

[0023] Specifically, when in use, the initial state of the device is as follows Figure 1As shown, the rack 304 rises and cooperates with the flip mechanism 2 to flip the adsorption box 4 outward, so that the adsorption box 4 is immersed in the box body 1. The adsorption box 4 is in a negative pressure state, and cooperates with the steel mesh in the adsorption tank 403 to adsorb the pulp. The mesh of the steel mesh only allows water to pass through, so it can adsorb the pulp to prevent the pulp from falling off after the adsorption box 4 is flipped. Then, the device returns to Figure 1 In the state shown, the lower pressing frame 5 limits the adsorption box 4, and then the lower pressing plate 503 drives the upper mold 504 to press down to form the pulp tableware.

[0024] Embodiment 1

[0025] like Figure 1-2 As shown, the rear surface of the box body 1 is fixedly connected with the mounting plate 101, the flip mechanism 2 includes a gear 201, a No. 1 air pump 202, a No. 2 air pump 203, a three-way pipe 204, a No. 1 solenoid valve 205, a No. 2 solenoid valve 206, a rotary joint 207 and a steel pipe 208, the upper surface of the mounting plate 101 is fixedly connected with the No. 1 air pump 202, the upper surface of the mounting plate 101 is fixedly connected with the No. 2 air pump 203, the inner surface of the box body 1 is rotatably connected with the steel pipe 208, one end of the steel pipe 208 is embedded with the rotary joint 207, one end of the rotary joint 207 is nested with the three-way pipe 204, and the three-way pipe One end of 204 is nested and connected with a No. 1 solenoid valve 205, the other end of the three-way pipe 204 is nested and connected with a No. 2 solenoid valve 206, the other end of the steel pipe 208 is fixedly connected with the gear 201, the steel pipe 208 and the adsorption box 4 are fixedly connected, the air inlet end of the No. 2 air pump 203 is connected and conducted through the No. 1 solenoid valve 205 and the three-way pipe 204, the air outlet end of the No. 1 air pump 202 is connected and conducted through the No. 2 solenoid valve 206 and the three-way pipe 204, the steel pipe 208 is a three-way pipe, and the upper end of the steel pipe 208 is threadedly connected with a threaded cover 401 at a position inside the adsorption box 4, and a through hole is opened on the outer surface of the threaded cover 401.

When the adsorption box 4 is inside the box body 1, the blowing can discharge the water in the adsorption box 4, and the threaded cover 401 prevents water from directly entering the steel pipe 208.
