Description

Technical Field

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and uses special molds on a molding machine to shape paper products of a certain shape. Its production process is completed by pulping, adsorption molding, drying and shaping, etc. It is harmless to the environment and can be recycled. When the flip pulp molding machine is in use, most of them use a motor to drive the shaft to rotate, and the shaft drives the lower mold to flip. When the hydraulic cylinder drives the upper mold to squeeze the lower mold, the shaft is under great pressure, which will cause damage to the shaft over time.

[0003] After searching, the existing patent (Announcement No.: CN219839893U) discloses a pulp molding machine with a flipping mechanism, including a pulp pool, a rotating shaft is arranged in the pulp pool, one end of the rotating shaft is connected to the bearing arranged on the left wall of the pulp pool, a motor is arranged on the right wall of the pulp pool, a mounting frame is arranged on the top of the pulp pool, an upper mold is arranged in the mounting frame, a hydraulic cylinder is arranged on the top of the mounting frame, the power output end of the hydraulic cylinder passes through the top of the mounting frame and is connected with the top of the upper mold, reinforcement plates are arranged on the front and back sides of the top of the pulp pool, slots are arranged on the opposite side walls of the two groups of reinforcement plates, and support mechanisms are arranged on the opposite side walls of the two groups of lower molds. The utility model can strengthen the support of the lower mold through the cooperation of the support mechanism, the reinforcement plate and the slot, so that when the hydraulic cylinder drives the upper mold to squeeze the lower mold, the pressure on the rotating shaft becomes smaller, thereby extending the service life of the rotating shaft.

[0004] However, in the implementation of relevant technologies, the following problems were found: the front and rear outer walls of the bidirectional screw are both sleeved with support rods, and the support rods are hollow structures. When the power output end of the hydraulic cylinder drives the upper mold downward to squeeze and close with the lower mold, the support rods can support the lower mold. However, the support rods are hollow structures, and their own supporting strength is relatively weak. When the upper mold squeezes the lower mold, the supporting effect provided by the support rods for the lower mold will be relatively weak. Moreover, the support rods will be easily squeezed and deformed when squeezed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: a pulp molding machine with a flipping mechanism, comprising a pulp pool 1, an upper mold group 2 is arranged at the upper end of the pulp pool 1, two lower molds 3 are arranged in the pulp pool 1, a flipping mechanism 4 for driving the two lower molds 3 to flip is arranged between the two lower molds 3, and supporting mechanisms 5 are respectively arranged on opposite sides of the two lower molds 3. The supporting mechanism 5 comprises a box body 501, and the box body 501 is fixedly connected to the lower mold 3. A two-way adjustment mechanism is arranged in the box body 501, and solid support rods 506 are respectively arranged at both ends of the two-way adjustment mechanism, and one end of the two solid support rods 506 extends to both sides of the box body 501 respectively, and the two-way adjustment mechanism is used to drive the two solid support rods 506 to move in both directions respectively, and one end of the two solid support rods 506 is respectively fixedly connected with a clamping block 507, and one side of the two clamping blocks 507 is respectively provided with a clamping seat assembly for clamping the two clamping blocks 507.

[0025] When in use, the lower mold 3 immersed in the pulp pool 1 absorbs the pulp, and the flipping mechanism 4 drives the lower mold 3 to flip, and then the two solid support rods 506 are driven to move in both directions through the two-way adjustment mechanism. The two solid support rods 506 will drive the two clamping blocks 507 to move in both directions respectively, and the two clamping blocks 507 will move into the two clamping seat assemblies respectively, so that the two clamping blocks 507 are clamped, thereby supporting and reinforcing the lower mold 3. When the upper mold group 2 squeezes the lower mold 3, the two solid support rods 506 will support the lower mold 3. Therefore, by using the two-way adjustment mechanism to drive the two solid support rods 506 to move in both directions, the two clamping blocks 507 can be respectively clamped into the two clamping seat assemblies, so that the lower mold 3 can be supported by the two solid support rods 506 with solid structures, which can provide a more stable supporting force for the lower mold 3 when it is squeezed by the upper mold assembly 2, thereby solving the problem in the related technology that the support rods are hollow structures and the supporting force is insufficient when squeezed by the upper mold, and are easily squeezed and deformed.

[0026] See also Figure 2 , Figure 3 and Figure 4 The bidirectional adjustment mechanism includes a motor 514, which is fixedly connected to the outer wall of the box body 501. The output end of the motor 514 extends into the box body 501 and is fixedly connected to a gear 502. Straight racks 503 are respectively meshed at both ends of the gear 502, and the two straight racks 503 are respectively slidably arranged on both sides of the inner wall of the box body 501 through a limit sliding mechanism. The two straight racks 503 are centrally symmetrically distributed with the center position of the gear 502 as the center, and two solid support rods 506 are respectively fixedly connected to one end of the two straight racks 503.

[0027] By starting the motor 514, the motor 514 drives the gear 502 to rotate, and the gear 502 drives the two spur racks 503 to move in both directions respectively. The two spur racks 503 will drive the two solid support rods 506 to move in both directions respectively, thereby realizing the two-way movement adjustment of the two solid support rods 506.

[0028] The limiting sliding mechanism includes a limiting sliding groove 504 and a limiting sliding block 505. The limiting sliding groove 504 is opened on one side of the inner wall of the box body 501, and the limiting sliding block 505 is fixedly connected to one side of the spur rack 503. The limiting sliding groove 504 is a T-shaped groove, and the limiting sliding block 505 is a T-shaped structure. The limiting sliding block 505 is slidably arranged in the limiting sliding groove 504. During the movement of the spur rack 503, the limiting sliding block 505 will always slide in the limiting sliding groove 504. In addition, the T-shaped limiting sliding groove 504 and the limiting sliding block 505 can prevent the limiting sliding block 505 from detaching from the limiting sliding groove 504 when sliding, thereby ensuring the stability of the spur rack 503 during movement.

[0029] See also Figure 1 and Figure 5 The holder assembly includes a reinforcing plate 508, which is fixedly connected to the upper end of the pulp pool 1. A slot 509 is provided on one side of the reinforcing plate 508, and clamping mechanisms are respectively provided on both sides of the inner wall of the slot 509.

[0030] The clamping mechanism includes a groove 510, which is opened on the inner wall of the slot 509. A plurality of springs 511 are fixedly connected to the bottom of the groove 510. One end of the plurality of springs 511 is fixedly connected to a limiting plate 512. A clamping block 513 is fixedly connected to the limiting plate 512, and one end of the clamping block 513 extends into the slot 509. The clamping block 513 is a square structure, and the end of the clamping block 513 close to the blocking block 507 is a rounded structure.

[0031] When the two solid support rods 506 drive the two clamping blocks 507 to move in both directions, the clamping block 507 will move toward the clamping slot 509. When the clamping block 507 moves into the clamping slot 509, the clamping block 507 will squeeze the two clamping blocks 513 into the two grooves 510 respectively. When the clamping block 507 is completely inserted into the clamping slot 509, under the action of the spring 511, the two clamping blocks 513 can clamp the clamping block 507, thereby improving the stability of the clamping block 507 in the clamping slot 509, and further improving the stability of the solid support rod 506, which helps to enhance the supporting effect of the solid support rod 506 on the lower mold 3.

[0032] The working principle and use process of the utility model are as follows: when in use, the lower mold 3 immersed in the pulp pool 1 absorbs the pulp, and the turning mechanism 4 drives the lower mold 3 to turn over, and then, by starting the motor 514, the motor 514 drives the gear 502 to rotate, and the gear 502 drives the two spur racks 503 to move in both directions respectively, and the two spur racks 503 will respectively drive the two solid support rods 506 to move in both directions, and the two solid support rods 506 will respectively drive the two clamping blocks 507 to move in both directions, and the clamping blocks 507 will move toward the clamping slot 509. When the clamping blocks 507 move into the clamping slot 5 09, the block 507 will squeeze the two clamping blocks 513 into the two grooves 510 respectively. When the block 507 is completely inserted into the slot 509, under the action of the spring 511, the two clamping blocks 513 can clamp the block 507, thereby improving the stability of the block 507 in the slot 509, and then improving the stability of the solid support rod 506. Therefore, the two blocks 507 are clamped, so as to support and reinforce the lower mold 3. When the upper mold assembly 2 squeezes the lower mold 3, the two solid support rods 506 will support the lower mold 3.
