Description

TECHNICAL FIELD

[0001] The utility model relates to vacuum heat insulation board production equipment technical field, specifically point to a kind of redundancy edge folding device for vacuum heat insulation board automatic production equipment. BACKGROUND

[0002] Vacuum heat insulation board is one of vacuum heat insulation materials, which is composed of filling core material and vacuum protection surface layer. It can effectively avoid heat transfer caused by air convection, greatly reduce the thermal conductivity, and is mainly used in refrigerators, freezers, refrigerated trucks, cold storage and other cold chain equipment, as well as external wall insulation systems of various buildings such as residential buildings, commercial buildings, office buildings and public facilities. It is an excellent material for reducing power consumption. With the improvement of the world's environmental protection and energy saving requirements, its application is becoming more and more widespread.

[0003] After the filling core material is combined with the vacuum protection surface layer, a redundant edge will be generated around it. The redundant edge needs to be bent and pressed flat to the top of the vacuum heat insulation board to ensure the use of the vacuum heat insulation board. Traditionally, there are two ways to fold the edge of the vacuum heat insulation board: one is manual folding, but its production efficiency is low, the working intensity is large, the product manufacturing cost is high, and the quality is unstable; the second is to use automatic equipment to solve the problem of labor cost and improve efficiency and quality, but the existing automatic equipment has a complex structure, and the operation process of each station is also complex. For example, a continuous edge press is needed to bend and press the redundant edge flat and then fix it with adhesive tape, but once the middle part of the continuous edge press is stuck, it must be repaired, which affects the production progress. Secondly, the existing edge folding mechanism simulates the manual folding process, which drives the up and down and left and right movement of the driving mechanism, drives the movement of the multiple edge folding plates arranged side by side, and folds the redundant edge of the vacuum heat insulation board upward and inward. Then, through the structure of the edge folding plate, it is reversed to rotate, and the lower end of the edge folding plate scrapes the redundant edge when it moves, thereby folding and pressing the redundant edge. However, the connection structure of the edge folding plate is complex, and once the rotation is stuck, the entire edge folding equipment will be stuck and stopped, and the operation process is relatively complicated and inefficient. Furthermore, the corner pinching mechanism is a way to pinch the height connection between the long and short edges inward, but it requires high flatness of the height connection, otherwise it will cause the bending and gathering of the pinching position, affecting the quality of the short edge folding.

[0004] Therefore, the research purpose of the utility model is to design a simple structure, easy to operate and easy to realize vacuum heat insulation board automatic production equipment. Utility model content

[0010] A gluing mechanism, which is installed on the gluing station, is used for smearing glue on the opposite sides of the upper surface of the vacuum heat insulation plate through a glue spraying or smearing mode;

[0011] An edge folding mechanism, which is installed on the edge folding station, is used for folding and fixing the redundant edge of the vacuum heat insulation plate, and the edge folding mechanism comprises a group of flexibly arranged flexible plates; after the flexible plates are moved and drive the redundant edge to be folded upward, the lower end of the flexible plate is abutted above the folded redundant edge to scrape it flat;

[0013] The edge folding mechanism comprises a group of mounting seats which are movably arranged on the two sides of the transmission mechanism in the up-down and left-right directions; the flexible plates are movably arranged below the corresponding mounting seats; when the vacuum heat insulation plate is conveyed to a position, the flexible plates are obliquely arranged on the two sides of the redundant edge of the vacuum heat insulation plate, and the lower end of the flexible plate is arranged directly below the redundant edge; during the edge folding action, the flexible plates are moved upward and inward, drive the redundant edge to be folded inward until the flexible plates are arranged above the vacuum heat insulation plate and are bent to be arranged in a V shape, and then the end of the flexible plate is pressed above the folded redundant edge.

[0014] The flexible plate is made of PU material.

[0015] The electromagnetic suction mechanism comprises a plurality of electromagnets which are arranged on the mounting plate in an equal interval and are uniformly distributed, and an iron piece which is connected with the electromagnet in one-to-one correspondence and is fixed to the lower end of the flexible plate through an adhesive mode; when the electromagnet is electrified, the iron piece is attracted to move upward, and then the lower end of the flexible plate connected with the iron piece is moved upward and is fixed.

[0016] The feed end of the frame is provided with a corresponding redundant edge sorting station. The redundant edge sorting station is provided with a sorting mechanism for sorting the redundant edges of the vacuum insulation board into an upright position. The sorting mechanism includes a set of V-shaped guide plates symmetrically installed on both sides of the transmission mechanism. The V-shaped guide plate includes an upright lower end and an integrally formed upper end that is inclined outward.

[0017] The transmission mechanism includes two synchronously operating conveyor belts spaced apart on the left and right.

[0019] Advantages of this utility model:

[0020] 1) This utility model improves the design of the folding mechanism for the production process of redundant edges in vacuum insulation panels. Based on mimicking the manual folding process, the folding mechanism uses a flexible plate made of materials such as PU to push, fold, press, and flatten the redundant edge, promoting a smooth adhesion of the folded redundant edge to the glued vacuum insulation panel. Utilizing the dual characteristics of strength and flexibility of the flexible plate, it ensures that the redundant edge can be flipped upwards during the folding action, and that it can also form a reverse bend after folding, with the end pressing and flattening the folded redundant edge as it moves forward. This not only ensures a smooth fold but also significantly simplifies the structure. Furthermore, the flexible plate can be easily cut and replaced according to the size of the equipment and the vacuum insulation panel, greatly improving convenience and reducing equipment costs. The flexible plate is a single piece, allowing for easy bending and quick resetting, effectively solving problems such as the traditional folding mechanism requiring multiple side-by-side folding plates and jamming caused by any folding plate not being folded, thus improving the practical effect of this utility model.

[0021] 2) After completing the folding action, the folding mechanism needs to go through a series of processes, including upward movement, backward movement, rotational reset, and downward movement, before it can continue with subsequent actions. This invention adds an electromagnetic suction mechanism to the flexible plate. The energization of the electromagnetic suction mechanism controls the setting position of the lower end of the flexible plate, thereby adjusting the distance between the bent end of the flexible plate and the upper surface of the vacuum insulation board. After the folding mechanism resets and the power is turned off, the flexible plate resets under its own elasticity. The operation process is simpler and faster, ensuring its practical effect. Furthermore, attaching an iron component to the outer surface of the lower end of the flexible plate not only does not affect the bending of the flexible plate, but more importantly, it locally increases the weight of the lower end, improving the effect of smoothing redundant edges and the efficiency of self-reset.

[0022] 3) This utility model also uses a sorting mechanism to put the redundant edge to be folded into a preliminary upright state, which facilitates the improvement of the efficiency of subsequent long edge folding; and by applying glue before folding, the redundant edge can be quickly scraped, glued and shaped after folding, which further improves the practical effect.
