Detailed Description
Referring to the attached drawings, the paper dinner plate forming machine in the embodiment comprises a guide post, a lifting support, a paper dinner plate forming mold and a lifting driving device. The guide post is arranged on a frame (such as a mounting seat of the frame), and the lifting bracket is arranged on the guide post so as to be convenient for the lifting bracket to lift on the guide post. The guide post can be arranged vertically or obliquely. The lifting driving device is in transmission connection with the lifting support, the lifting support is driven to lift on the guide pillar through the lifting driving device, the lifting driving device can adopt an oil cylinder, an air cylinder or a motor and the like, the lifting driving device can be arranged on the mounting plate, and the mounting plate is connected to the guide pillar. The male mould of the paper dinner plate forming mould is positioned above the female mould of the paper dinner plate forming mould, a male mould seat of the male mould of the paper dinner plate forming mould is connected to the lifting support, and the lifting support drives the whole male mould to lift. After the forming, the paper dinner plate can be taken out by adopting air blowing or manual mode.
The mould for forming the paper dinner plate in the embodiment comprises a male mould and a female mould, and the paper between the male mould and the female mould is formed into the paper dinner plate through the closing of the male mould and the female mould.
The main cavity is arranged on the female die and is a separation convex ridge on the female die. The paper dinner plate has a plurality of cavities, generally at least two, usually three cavities, and the paper dinner plate forming mold and the paper dinner plate forming machine corresponding to the three cavities are shown in the figure. The separation convex ridge separates the main cavity from the main cavity on the female die, namely the main cavities are separated from each other by the separation convex ridge.
The male die comprises a male die holder, a pressing frame and a model block, wherein the pressing frame and the model block are connected to the male die holder. The pressing frame and the model block can act along with the male die holder so as to be matched with the female die.
The pressing frame surrounds the model block and is correspondingly matched with the female die, so that the pressing frame can be pre-pressed on the female die when the dies are closed, the edge part of the paper positioned between the pressing frame and the female die is pressed on the female die by the pressing frame, the middle of the pressing part is a main cavity and a separation convex ridge, and then the model block in the middle of the pressing frame moves towards the main cavity of the female die to be subsequently matched.
The first elastic part is arranged between the pressing frame and the male die holder, the pressing frame protrudes outwards relative to the die block in the initial state, the pressing frame is firstly pressed on the female die during die assembly, and then the die block enters the main cavity of the female die. After the pressing frame and the female die are assembled, the first elastic piece can deform so that the pressing frame and the male die holder can be further closed, and the die block on the male die holder can be assembled with the main cavity on the female die subsequently. And the first elastic part with proper elasticity can be selected, so that when the edge part of the paper is pressed on the female die by the pressing frame, the pressing pressure can be selected to meet the forming requirement, the prepressing can be achieved to keep the paper stable, and the pressed paper can be pulled to facilitate the subsequent further forming. When the mold is separated, the first elastic piece can recover.
The model blocks are arranged in at least two groups, the model blocks are correspondingly matched with the main cavities, and the paper is pressed into the corresponding main cavities by the model blocks for matching and forming during die assembly and forming. The mold blocks are provided with separation grooves, the separation grooves are used for separating the mold blocks from the mold blocks and are correspondingly matched with the separation convex ridges, and the separation grooves are also matched with the separation convex ridges to press paper on the separation convex ridges during mold closing and forming.
Each set of model blocks includes a first portion and a second portion. The separation grooves are positioned between the corresponding first parts, a second elastic piece is arranged between the first parts and the male die holder, and the first parts are protruded outwards relative to the second parts in an initial state. When the mould is closed, the first part of the mould block contacts the paper firstly relative to the second part, the second elastic piece can deform, the paper is pressed into the main cavity by the first part, and the separation grooves are positioned between the corresponding first parts, so that the paper is pressed to the separation ridges by the separation grooves to form the ridges of the paper dinner plate while the paper is pressed into the main cavity by the first part, and the ridges between the main cavity and the main cavity of the paper dinner plate and the parts of the main cavity connected with the ridges can be formed firstly, and the local gradual forming is achieved firstly. And then, the second part contacts the paper and enters the main cavity to be matched with the main cavity to be integrally molded. And (4) splitting the mold after the molding is finished, returning the second part, then returning the second elastic piece and the first part, and finally returning the first elastic piece and the pressing frame to wait for the next mold closing.
This paper dinner plate forming die is at the fashioned in-process of compound die, withholds the paper through pressing the frame first pre-compaction, then carries out local gradual shaping by the cooperation of the first part of model piece and the separation recess between the first part again, and the main cavity of the remaining part of second part cooperation shaping by the model piece again at last to can avoid the main cavity of paper dinner plate and the convex ridge part department between the main cavity to tear, the shaping effect is better. Wherein, the first elastic component and the second elastic component both adopt springs (such as compression springs and extension springs). In addition, the corners of the male die and the female die, which are used for forming, are provided with smooth and arc-shaped transition, so that the forming effect is better.
In addition, the second part can be directly and fixedly arranged on the male die holder more stably and reasonably, or a third elastic part (such as a spring) is arranged between the second part and the male die holder to play a role in buffering.
The first parts of the model blocks are connected with each other to form a central module, and the separation grooves are arranged on the central module. I.e. the side walls of the first part form separation grooves with the side walls of the first part. The integrated central module is convenient to assemble, has stronger integrity and can not have split traces after being formed.
In addition, in order to further enhance the stability, the first part is provided with a sliding block (such as a dovetail block), the second part is provided with a sliding groove (such as a dovetail groove), and the sliding block is arranged in the sliding groove, so that the first part and the second part move relatively more stably.
In addition, the female die is also connected with a heating device (such as a heating wire, a heating pipe or an electric heating wire) so that the formed paper dinner plate is better shaped and has better forming effect.
