[0003] The current pulp forming technology is mainly based on vacuum suction filtration, but the current vacuum suction filtration production requires the transfer of semi-finished wet embryos from the cold pressing device to the hot pressing device during the production process, which consumes a lot of manpower and time, greatly affecting the production efficiency of the product; the hot pressing process of pulp will release polluting gases, polluting the ecological environment and working environment. In order to solve the above problems, the present invention provides a green and efficient cold-pressing and hot-pressing integrated pulp forming equipment that adopts vacuum suction filtration technology, can absorb waste gas, has high working efficiency, and can perform both cold pressing dehydration and hot pressing forming. Summary of the invention

[0004] The present invention aims to solve the above problems and provide a green and efficient cold-pressing and hot-pressing integrated pulp forming device which adopts vacuum filtration technology, has high working efficiency, can perform both cold-pressing dehydration and hot-pressing forming, and can purify polluted gases.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] The green and efficient cold-pressing and hot-pressing integrated pulp forming device of the present invention comprises a raw material tank, a vacuum suction filter device, a circulation purification system, an observation window, a closed frame, a frame, an eccentric wheel drive hot-pressing forming device, a cam rack transmission system, and a motor; the motor drives a gear 4 to rotate through a reducer, and the gear 4 rotates a cold-pressing and dehydrating roller through gear meshing, and at the same time drives the eccentric wheel drive hot-pressing forming device to reciprocate up and down through a crank rocker, and the vacuum suction filter device to reciprocate left and right, and the cold-pressing and dehydrating roller controls the vacuum suction filter roller to rotate through the cam rack transmission system.

[0007] Furthermore, the eccentric wheel transmission hot pressing forming device includes: gear 1, shaft 1, speed gear, internal gear, cold pressing and dehydrating roller, bearing 1, short shaft 1, ear plate, shaft 3, bearing 2, short shaft 2, hot pressing and dehydrating mold mounting boss, hot pressing and dehydrating mold, rod 1, shaft 2, eccentric wheel 1, gear 4; the motor drives the gear 4, the external gear 2 welded on the eccentric wheel 2 is meshed with the gear 4, the gear 1, the eccentric wheel 1 and the eccentric wheel 2 are key-connected to the shaft 1, the gear 1, the speed gear installed on the frame through the sliding bearing, and the internal gear welded on the cold pressing and dehydrating roller are meshed and rotated in sequence, the transmission ratio of the gear 1 to the internal gear is 4, the gear 1 rotates one circle, and the cold pressing and dehydrating roller rotates 90 degrees; the rod 1 and the notch 1 above form a crank-connecting rod mechanism, the eccentric wheel 1 rotates one circle, the crank-connecting rod mechanism completes a cycle of motion, and the hot pressing and dehydrating mold reciprocates up and down once. Therefore, when shaft 1 rotates, the hot pressing forming mold moves from the top to the bottom, and the cold pressing and dehydrating mold with the wet embryo after being squeezed by the vacuum suction filter mold on the cold pressing and dehydrating roller rotates clockwise. When it rotates to the bottom of the hot pressing and forming mold, the hot pressing and forming mold moves to the lower end of the slot 1 and squeezes the wet embryo with the cold pressing and dehydrating mold to further reduce the moisture content of the wet embryo to complete the hot pressing and obtain the pulp forming product.

[0008] Furthermore, the vacuum filtration device comprises: a vacuum filtration mold, a vacuum filtration mold mounting boss, a vacuum filtration roller, a gear 3, a bearing 3, a shaft 6, a rack, an L-rod, an L-shaped notch, a rod 2, and a notch 2; the vacuum filtration roller is evenly distributed with 4 vacuum filtration mold mounting bosses on which a convex forming mold can be mounted, the vacuum filtration roller is connected with the vacuum filtration mold by bolts, the vacuum filtration roller is connected with the shaft 6 by a key, the shaft 6 is interference fit with the inner ring of the bearing, the outer ring of the bearing 3 is in contact with the lower surface of the notch, and there is a gap with the upper surface of the notch, the bearing 3 can roll left and right, and the gear 3 is welded on the vacuum filtration roller. On the filter roller, the rack is welded on the L rod. When the outer ring of the bearing 3 rolls to the left along the notch direction, the gear 3 meshes with the rack. In this process, the shaft 6 and the inner ring of the bearing 3 will be subjected to the torque transmitted by the gear 3 and rotate counterclockwise during the horizontal movement to the left. At this time, the vacuum suction filter mold with the raw material adsorbed originally located below rotates counterclockwise to the horizontal position. When the outer ring of the bearing 3 rolls to the right along the notch direction, the gear 3 does not mesh with the rack. In this process, the shaft 6 and the inner ring of the bearing 3 only move horizontally and do not rotate. The vacuum suction filter mold in the horizontal position moves to the right and contacts the cold pressing dehydration mold to squeeze out the moisture of the raw material, completing the cold pressing.

[0009] Furthermore, the cam rack transmission system includes a gear 2, a cam, a shaft 5, a cold press dehydration mold, a cold press dehydration mold mounting boss, a rod 2, a shaft 4, an external gear 2, an eccentric wheel 2, a spring, an L rod, and an L-shaped notch; the shaft 1 is key-connected with the eccentric wheel 2 and rotates coaxially, the eccentric wheel 2, the rod 2 and the slot 2 constitute a crank rocker mechanism, the vacuum suction filter roller completes a horizontal reciprocating motion, the external gear 2 welded on the eccentric wheel 2 meshes with the gear 2, the crank rocker mechanism completes a cycle of motion when the shaft 1 rotates one circle, the cam welded on the gear 2 rotates one circle, when the vacuum suction filter roller is located at the left end of the slot 2 and moves to the right end, the large radius circumference of the cam contacts the L rod, the L rod compresses the spring, and the rack does not mesh with the gear 3, when the vacuum suction filter roller is located at the right end of the slot 2 and moves to the left end, the small radius circumference of the cam contacts the L rod, the spring resets and pushes up the L rod, and the rack meshes with the gear 3.

[0010] Furthermore, the frame includes a base, a front plate, and a rear plate. The front plate and the rear plate of the frame are provided with slots 2 for constraining the movement of the shaft 1, slots 1 for constraining the movement of the hot pressing mold, and the shafts for positioning the speed change gear and the cam.

[0011] Furthermore, the closed frame is connected to the ground through anchor bolts to form a closed working environment. There is an observation window on the closed frame to facilitate observation of the working conditions of the internal machine. A circulating purification system is installed on the top of the closed frame. The circulating purification system is sealed to the closed frame through an air inlet and an air outlet. The air inlet is located directly above the eccentric wheel drive hot pressing forming device, and the frame is connected to the bottom of the closed frame.

[0012] The equipment is in a closed working environment when working. It is equipped with an observation window to observe the internal working conditions in real time. The water vapor released by pulp hot pressing contains polluting gases. In a closed environment, the circulating purification system absorbs the polluted air through the air inlet and purifies it, and then discharges the purified fresh air into the closed environment through the air outlet, so as to achieve the purpose of purifying the polluted gases generated by the pulp forming process.
