An extrusion mechanism for a pulp molding machine

Abstract

The present invention relates to the technical field of pulp molding, and discloses an extrusion mechanism for a pulp molding machine, which includes a mold frame arranged on a frame. A carriage is slidably connected to the mold frame, and an upper mold is slidably connected to the carriage. A lower mold is arranged below the upper mold in a liftable manner. Pressing plates are arranged on both sides of the carriage on the mold frame, and the pressing surfaces of the pressing plates are attached to the upper surface of the carriage. By arranging the pressing plates and making the pressing surfaces of the pressing plates attached to the upper surface of the carriage, during the process of the lower mold moving upward to close the mold with the upper mold, the carriage is restricted by the pressing plates, so that the carriage will not move upward. At the same time, the lower mold moves upward under the action of its driving mechanism, thereby squeezing the product between the upper mold and the lower mold, reducing the moisture inside the product in the molding stage, saving the subsequent working time, and improving the production efficiency. At the same time, the carriage will not move upward, avoiding the slider of the upper mold from disengaging from the guide rail and ensuring the use of the molding machine.

Description

Technical Field

[0001] The present invention relates to the technical field of pulp molding, and particularly to an extrusion mechanism for a pulp molding machine. Background Art

[0002] A pulp molding machine is a commonly used device for producing pulp products. During the working process, the lower mold sucks materials in the pulp tank, then moves upward to perform die pressing with the upper mold, and after forming, the materials are received by a receiving table. However, the moisture content of the products produced by the existing molding machines is relatively high, which will increase the subsequent workload and affect the production efficiency. At the same time, since the lower mold is driven by a driving mechanism to move upward and close the mold with the upper mold during the working process, under the long-term upward acting force, the slider of the upper mold may disengage from the guide rail, affecting the continuous operation of the pulp molding machine. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an extrusion mechanism for a pulp molding machine, which reduces the moisture inside the products in the forming stage, saves the subsequent working time, improves the production efficiency, and prevents the slider of the upper mold from disengaging from the guide rail.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] An extrusion mechanism for a pulp molding machine includes a mold frame provided on a frame. A carriage is slidably connected to the mold frame. An upper mold is slidably connected to the carriage. A lower mold is provided below the upper mold in a liftable manner. Pressing plates are provided on both sides of the carriage on the mold frame, and the pressing surfaces of the pressing plates are in contact with the upper surface of the carriage.

At the same time, the lower mold moves upward under the action of its driving mechanism, so as to extrude the product between the upper mold and the lower mold, reduce the moisture inside the product in the molding stage, save the subsequent working time, and improve the production efficiency. At the same time, protected by the pressing plates, the vehicle frame will not move upward either, avoiding the slider of the upper mold from disengaging from the guide rail and ensuring the use of the molding machine.

[0018] The following will further describe in detail the specific embodiments of the present invention with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0019] As Figure 1-2As shown in the figure, an extrusion mechanism for a pulp molding machine according to a preferred embodiment of the present invention includes a mold frame 2 provided on a frame 1. A carriage 3 is slidably connected to the mold frame 2. An upper mold 4 is slidably connected to the carriage 3. A lower mold 5 is provided below the upper mold 4 in a liftable manner. Pressing plates 6 are provided on both sides of the carriage 3 on the mold frame 2. The pressing surface of the pressing plate 6 is in contact with the upper surface of the carriage 3. Preferably, two pressing plates 6 are provided on each side of the carriage 3, and the two pressing plates 6 are spaced apart.

[0020] For the extrusion mechanism for a pulp molding machine based on the above technical features, by providing pressing plates 6 on both sides of the carriage 3 on the mold frame 2 and making the pressing surface of the pressing plate 6 in contact with the upper surface of the carriage 3, during the process of the lower mold 5 moving upward to close the mold with the upper mold 4, the carriage 3 is restricted by the pressing plates 6, so that the carriage 3 will not move upward (or deform upward). At the same time, the lower mold 5 moves upward under the action of its driving mechanism, so as to extrude the product between the upper mold 4 and the lower mold 5, reduce the moisture inside the product in the molding stage, save the subsequent working time, and improve the production efficiency. At the same time, protected by the pressing plates 6, the carriage 3 will not move upward, avoiding the slider of the upper mold 4 from disengaging from the guide rail and ensuring the use of the molding machine. The structure of the present invention is simple, has good use effects, and is easy to promote and use.

[0021] In this embodiment, a guide rail 7 is provided on the mold frame 2. A slider 8 is provided on the lower surface of the carriage 3. The slider 8 is slidably connected to the guide rail 7. At the same time, to further ensure the sliding effect, a chute adapted to the guide rail 7 is provided on the slider 8, and balls are provided between the chute and the guide rail 7. The sliding effect is improved by providing the balls. However, the balls of the existing molding machines are easily damaged during the extrusion process of the lower mold 5 and the upper mold 4. Since the pressing plates 6 are provided in the present invention, the upward movement of the carriage 3 is restricted, thereby avoiding the balls from being crushed. Additionally, preferably, the guide rails 7 are two relatively arranged ones, and the two guide rails 7 are respectively provided on both sides of the carriage 3, ensuring the movement stability of the carriage 3 on the guide rails 7.

[0022] Please refer to the appendix Figure 3, in this embodiment, top plates 9 are provided on both sides of the frame 3 corresponding to the pressing plates, and the pressing surface of the pressing plate 6 is attached to the upper surface of the top plate 9. Thus, direct connection between the frame 3 and the pressing plate 6 is avoided, and deformation of the frame 3 is avoided. Additionally, to ensure a better pressing effect, the pressing plate 6 includes a mounting portion 61 and a pressing portion 62 arranged perpendicular to each other, and the mounting portion 61 and the pressing portion 62 are connected by a connecting portion 63. At the same time, a mounting plate 64 is provided at one end of the mounting portion 61 away from the pressing portion 62, and the mounting plate 64 is connected to the mold frame 2 to facilitate the installation of the pressing plate 6. A pressing plate 65 is provided at one end of the pressing portion 62 away from the mounting portion 61, the pressing plate 65 is arranged parallel to the top plate 9, and the lower surface of the pressing plate 65 is attached to the upper surface of the top plate 9. Thus, the pressing plate 6 and the top plate 9 have a larger contact surface, ensuring the stress area of the top plate 9 and avoiding damage to the top plate 9.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
