Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, and in particular to a pulp molding cam pressure device. Background Technology

[0002] Pulp molding, also known as stereolithography, uses pulp as raw material and molds it into a specific shape using special molds on a molding machine. Pulp molding offers advantages such as renewable raw materials, convenient transportation, and environmental friendliness, and is mainly used for food containers, tableware, and product trays. The production of pulp molding products involves processes such as raw material pulping, batching, molding, and hot pressing. During the hot pressing process, hot pressing equipment is typically required. Currently, most hot pressing equipment on the market uses an eccentric wheel structure, which limits its practicality due to its inability to operate at high speeds and high pressures simultaneously, resulting in higher energy consumption and reduced production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pulp molding cam pressure device in view of the above-mentioned defects of the prior art. By better optimizing the cam curve, the pulp molding cam pressure device can work faster, more smoothly and at high pressure, thereby improving production efficiency, with high practicality and low energy consumption.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A pulp molding cam pressure device includes a frame on which a cam mechanism and an upper mold lifting assembly are mounted. The cam mechanism includes a cam drive motor and a cam, which is driven by the cam drive motor. The upper mold lifting assembly includes an upper mold lifting cylinder and an upper mold, which is driven by the upper mold lifting cylinder. The upper end of the upper mold abuts against the cam. The outer side of the cam is provided with a cam surface, and the cam surface is provided with the highest point and the lowest point of the cam.

[0006] Preferably, the upper end of the upper mold is provided with an upper mold pressure plate, which abuts against the cam surface.

[0007] Preferably, the cam includes a first cam and a second cam, both of which are connected to the cam drive motor via a drive shaft.

[0008] Preferably, a hot-pressing lower mold corresponding to the upper mold is provided on the inner side of the frame, and the hot-pressing lower mold is located directly below the upper mold.

[0009] Preferably, when the highest point of the cam rotates downward, the upper mold presses down; when the lowest point of the cam rotates downward, the upper mold lifting cylinder drives the upper mold to rise.

[0010] Preferably, the bottom of the frame is provided with several support feet, and the cam drive motor and the upper mold lifting cylinder are both arranged from top to bottom on the side of the frame.

[0011] The pulp molding cam pressure device provided by this utility model, using the above technical solution, has the following beneficial effects: The frame of the pulp molding cam pressure device is equipped with a cam mechanism and an upper mold lifting assembly. The cam in the cam mechanism is driven by a cam drive motor, and the upper mold in the upper mold lifting assembly is driven by an upper mold lifting cylinder. The upper end of the upper mold abuts against the cam. A cam curved surface is provided on the outer side of the cam, and the cam curved surface has the highest point and the lowest point of the cam. By better optimizing the cam curve, the pulp molding cam pressure device can work more quickly, smoothly, and under high pressure, simultaneously achieving high-speed operation and high-pressure conditions, thereby improving production efficiency, increasing practicality, and reducing energy consumption.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
