Paper Plastic Shaping Machine and Its Shaping Process

Abstract

The invention relates to a paper-plastic shaper and a shaping technology thereof. The paper-plastic shaper comprises an upper mould assembly provided with an upper mould, and a lower mould assembly provided with a lower mould. The lower mould assembly comprises a rotary table rack (101). A rotating shaft (102) is vertically installed on the rotary table rack (101). A rotary connecting disc (103) is installed at the top of the rotating shaft (102) in a sleeving mode by means of key joint. Multiple guide columns (105) are installed on the rotary connecting disc (103) in the vertical direction. A rotary table (104) is arranged on the rotary connecting disc (103) in a shelved mode and provided with connecting holes for the guide columns (105) to be inserted. Each guide column (105) is sleeved with a lubricating sleeve (106). The lubricating sleeves (106) are located between the guide columns (105) and the inner walls of the connecting holes. The paper-plastic shaper and the shaping technology thereof effectively stop stress transmission and can ensure transposition precision.

Description

technical field [0001] The invention relates to a paper-plastic shaping machine and a shaping process thereof, belonging to the technical field of paper products. Background technique [0002] At present, pulp molded products are a common product in the market. The production of such pulp molded products requires the use of hot press shaping machine equipment; during the production process, the hot press shaping machine drives the upper template to move up and down through the cylinder and cooperates with the lower template. Operation; [0003] Conventional shaping machines mainly include oil pressure heat shaping machine, conveyor belt loading automatic heat pressing machine, and horizontal turning automatic heat pressing machine; among them, oil pressure heat shaping machine has simple structure and low manufacturing cost, but The efficiency is low, and there are safety hazards due to the need for manual loading and unloading; the model of the conveyor belt loading automa...

Problems solved by technology

[0003] Conventional shaping machines mainly include oil pressure heat shaping machine, conveyor belt loading automatic heat pressing machine, and horizontal turning automatic heat pressing machine; among them, oil pressure heat shaping machine has simple structure and low manufacturing cost, but The efficiency is low, and there are safety hazards due to the need for manual loading and unloading; the model of the conveyor belt loading automatic hot press is compact and efficient, but the shape of the products in the pulp molding industry is changeable after drying, but it is in There are congenital defects in the positioning, resulting in a large number of waste products; the structure of the horizontal flip automatic heat press is complex, and the efficiency is acceptable, but because the extrusion direction is in the horizontal position, it needs to maintain the vacuum for a long time, which will inevitably lead to the appearance of the product. There are obvious defects; for this reason, some companies have developed a "three-sided rotary hot-pressing paper-plastic shaping machine" as disclosed in Chinese patent ZL201410113102.4, which adopts a three-station method to realize "loading, hot-pressing shaping, and unloading "Synchronous and synergistic effect, all three operation processes are separated, which not only improves efficiency, but also has high safety performance, effectively preventing accidents during operation;

[0004] However, in actual use, it is found that since the turntable of the above structure adopts a fixed connection method, during the hot pressing process of the upper and lower dies, the force on the turntable will be transmitted to the rotating shaft that drives the turntable to rotate, resulting in its fracture and affecting its service life; and it lacks the corresponding positioning function. After long-term operation, due to the existence of accumulated errors, it will cause deviations in the positions during the conversion process of the three positions, making the upper and lower dies unable to be combined, which seriously affects the Product quality; for this reason, need a kind of brand-new shaping machine and shaping technology thereof that can solve the above problems
