Problems solved by technology

Each formwork needs to be connected with the removal mold when transferring, which is difficult to install and high in manufacturing cost;
[0005] (2) The 12-face rotary hub machine has a large volume and weight due to its many installation surfaces, and it is inconvenient to maintain and repair;
[0006] (3) The weight of the 12-face rotary hub machine is large. Since the formed product needs intermittent movement, the drive system has to overcome its large inertial force, so the cam split drive mechanism itself is made very large, and the drive equipment is also correspondingly large, costing very high;
[0007] (4) Due to the large driving power requirements of the 12-face rotary hub machine and the high requirements for mold movement accuracy, the cost of the corresponding control system also increases;
[0008] (5) Due to the large number of molds and the large inertia force of the 12-face rotary hub machine, the transfer speed of the molds is greatly limited, which affects the production efficiency of paper mold products

Embodiment Construction

[0032] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] see in conjunction Figure 1 to Figure 6 As shown, a double-sided rotary hub forming machine for pulp molding includes a rotary hub intermittent drive mechanism 2 installed on a pulp box 1, a rotary hub forming mechanism 3, and a product removal mechanism 4. The rotary hub intermittent drive mechanism 2 is respectively connected with The hub forming mechanism 3 and the product removal mechanism 4 are connected. The pulp box 1 is composed of a pulp inlet pipe 11, a pulp inlet tank 12, a pulp storage tank 13, an overflow tank 14, and a return pipe connected in sequence. The hub intermittent drive mechanism 2 is a cam split drive mechanism, including a drive motor-reducer 21 and a cam divider 22, the drive motor-reducer 21 is installed on the base of the pulp box 1, and the cam divider 22 Installed at the end of the...

Abstract

The invention provides a molded pulp two-face rotary hub forming machine which comprises a rotary hub intermittent drive mechanism, a rotary hub forming mechanism and a product discharge mechanism, wherein the rotary hub intermittent drive mechanism, the rotary hub forming mechanism and the product discharge mechanism are installed on a pulp box. The rotary hub intermittent drive mechanism is connected with the rotary hub forming mechanism and the product discharge mechanism. Forming molds of the rotary hub forming mechanism are opposite to a discharge mold of the product discharge mechanism. The rotary hub forming mechanism and the product discharge mechanism are connected with a vacuum source and a pressure source respectively. The molded pulp two-face rotary hub forming machine is characterized in that the rotary hub forming mechanism comprises a cuboid rotary hub and two forming air chambers, the two faces of the rotary body of the cuboid rotary hub are open, the forming air chambers are arranged on the two symmetrical side faces of the cuboid rotary hub and are parallel to a spindle of the rotary hub, and the forming molds are arranged on the outer planes of the forming air chambers respectively. According to the molded pulp two-face rotary hub forming machine, only three mold plates are needed, two mold plates are used for forming, one mold plate is used for transferring, the device design is simplified, the manufacturing cost is reduced, the size is small, the weight is low, inertia force needing to be overcome by a driving system is reduced, and therefore the system can run at higher speed.

Description

technical field [0001] The invention belongs to the pulp molding industry, and relates to a forming machine in the production process of pulp molding products, in particular to a pulp molding double-sided rotary hub forming machine. Background technique [0002] The forming principle of the rotary hub machine is to use the mold to absorb the pulp. The surface of the mold is covered with metal mesh, and there are many small holes on the surface of the mold that communicate with the bottom of the mold, and the bottom plate of the mold is connected with the hub template. The suction of each template makes the paper fibers in the pulp adsorb on the mold with a certain shape, and the moisture is taken away by the vacuum from the small holes. Then the mold is rotated to the transfer position, the product and the mold are separated by compressed air, and the product is transferred to form a paper product with a certain shape. [0003] At present, the rotary hub forming mechanism ...
