Description

Technical Field

[0001] The invention relates to the technical field of vacuum insulation panel production equipment, and in particular to automatic vacuum insulation panel production equipment, which is used for folding redundant edges of vacuum protection surface layers of vacuum insulation panels. Background Art

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

[0003] After the filling core material is compounded with the vacuum protective surface layer, redundant edges will be generated around it. The redundant edges need to be bent and flattened to the top of the vacuum insulation panel by folding to ensure the use of the vacuum insulation panel. Traditionally, there are two main ways to fold the edges of vacuum insulation panels: one is manual folding, but its production efficiency is low, the work intensity is high, the product manufacturing cost is high, and the quality is unstable; the second is to use automated equipment for processing to solve labor costs, improve efficiency and quality, but the existing automated equipment has a complex structure and the operation process of each station is also complicated. For example, a continuous edge pressing machine is needed to bend and flatten the redundant long edges first and then fix them with tape, but once the continuous edge pressing machine is stuck in the middle, it must be stopped for repair, affecting the production progress; secondly, the existing folding mechanisms all imitate the process of manual folding, and are driven by the driving mechanism to move up and down and left and right, driving the many folding plates arranged side by side to move and fold the redundant edges of the vacuum insulation panel upward and inward, and then rotate them in the opposite direction through the structure of the folding plate. As the folding plate moves, its lower end scrapes the redundant edge, and then folds and presses the redundant edge. However, the folding plate not only has a complex connection structure, but once its rotation gets stuck, the entire folding equipment will get stuck and stop, and its operation process is relatively cumbersome, and its efficiency stagnates. Furthermore, the angle pinching mechanism pinches the angle by folding the height connection between the long folded edge and the short folded edge inward, but it has high requirements on the flatness of the height connection, otherwise it will cause the bends to gather at the angle pinching position and affect the quality of the subsequent short side folding.

[0004] Therefore, the research purpose of the present invention is to design an automatic production equipment for vacuum insulation panels with a simple structure, simple operation process and easy implementation. Summary of the invention

[0012] The hot stamping plate is made of die steel and is processed by rusting and grinding in sequence until smooth and evenly distributed pits are formed on its surface.

[0016] Advantages of the present invention: 1) The present invention is used in the production process of redundant edge folding and shaping of vacuum insulation panels through the improved design of the operating procedures of long edge arrangement, long edge gluing, long edge folding, angle pinching, corner transition, short edge gluing, and short edge folding. The redundant long edges to be folded can be placed in an initial upright state through long edge arrangement, which is convenient for improving the efficiency of subsequent long edge folding. By gluing first and then folding, the redundant edges can be quickly shaped and fixed after folding. The folding mechanism, based on the folding process of imitating manual folding, uses flexible plates made of PU and other materials to push, fold, press and flatten the redundant edges, so as to promote the folded redundant edges to adhere smoothly to the vacuum insulation panel. The flexible plates themselves have the dual characteristics of strength and flexibility, which can not only ensure that they are sufficient to push the redundant edges to flip upwards during the folding action, but also can automatically turn over after the redundant edges are folded. The body forms a reverse bend, which can effectively avoid scratches or cuts caused by traditional rigid contact, and the end is pressed and scraped flat as it moves forward to flatten the redundant edge after folding. Not only is the structure significantly simplified on the basis of ensuring the flatness of the folded edge, but the flexible plate can be cut and replaced at will according to the size of the equipment and the vacuum insulation panel, which greatly improves the simplicity and reduces the equipment cost; and the flexible plate is a whole piece structure, which can be bent at will and quickly reset, effectively solving the problem that the traditional folding mechanism must be composed of multiple folding plates arranged side by side, and any folding plate will cause jamming if it is not folded, thereby improving the practical effect of the present invention; Furthermore, after completing the folding action, the folding mechanism needs to go through the processes of moving up, withdrawing, rotating and resetting, and moving down before continuing the subsequent actions. The present invention adds an electromagnetic suction component on the basis of the flexible board, and controls the setting position of the lower end of the flexible board by whether the electromagnetic suction component is powered on, thereby regulating the bending of the flexible board so that the bending end of the flexible board is set at a distance from the upper end surface of the vacuum insulation board; after the folding mechanism is reset, the power is turned off again, and the flexible board is reset under the action of its own elasticity. The operation process is simpler and faster, and the operation efficiency is improved to ensure its practical effect. In addition, bonding the iron parts on the outer side of the lower end of the flexible board will not only not affect the bending of the flexible board, but more importantly, it can locally increase the weight of its lower end to improve the effect of scraping the redundant edges of the flexible board and the efficiency of its self-resetting.

[0017] 2) The present invention realizes the angle pinching action by improving the coordination of the positioning member, the flattening member and the pressing member, and uses the positioning member to flatten the redundant short side, and forms the positioning through the inclined surface end of the positioning member, and then when the flattening member is pushed inward along the upper surface of the positioning member, it pushes the redundant long side to move inward along the inclined surface of the positioning member to form an inwardly inclined inclined side, forming an inward fold; and after the positioning member is moved back and reset to its position, the outer side surface of the flattening member and the redundant short side end of the vacuum insulation panel are spaced apart to form a pressing area that is convenient for the pressing member to move down and fix the angle, and then the pressing member is moved down to press and fix the folded corner part to form a fold line. The angle pinching structure of the present invention is simpler, the operation method is simpler, and it is easier to implement, thereby improving the efficiency of angle pinching.

[0018] 3) The action of pinching the corner affects the quality of the subsequent short folded edges and whether the redundant edges will bulge out. Therefore, the quality of pinching the corner needs to be ensured, and the flatness of the redundant short edges will affect the action of the flattening member. On this basis, a hot stamping component is added to the positioning member, and the hot stamping component moves with the positioning member to perform hot stamping and flattening on the redundant short edges. However, due to the limitation of the setting position, it is not easy to install traditional hot stamping equipment at this position, and the lines connected to the traditional hot stamping equipment will affect the movement of the positioning member. Therefore, the present invention sets a hot stamping plate that can be relatively moved and attached to the bottom surface of the L-shaped plate of the positioning member. The left and right movement of the positioning member is used to drive the hot stamping plate to move relatively and generate heat by friction. While the positioning member flattens the redundant short edges, it generates heat by friction and hot stamping to flatten the redundant short edges. The hot ironing plate is connected to the positioning piece by means of a slider and a guide groove, and the end of the hot ironing plate protrudes from the positioning piece. During the angle pinching action, the hot ironing plate moves in the opposite direction to the positioning piece under the action of the mutual force and is blocked by the positioning piece. When the positioning piece is reset, the hot ironing plate moves toward each other and resets under the dual action of the mutual force and the elastic force of the elastic piece to continue to generate heat by friction, thereby ensuring that the temperature of the hot ironing plate is maintained at 35-50°C, ensuring the hot ironing effect and the practical effect of the present invention.

[0019] 4) The hot stamping plate of the present invention is made of die steel, and preferably model H13 mold steel, which has high wear resistance and fast thermal conductivity. It is rust-treated and then polished until its surface is flat and evenly distributed with pits, so that the surface of the hot stamping plate is not only smooth and flat to ensure that the hot stamping plate and the positioning piece can move relative to each other, but also can increase the friction coefficient of the hot stamping plate, thereby increasing the friction heat generation temperature, ensuring the practical effect of self-heating of the hot stamping component, achieving hot stamping and flattening of redundant short edges, and promoting the completion of the angle pinching action.

DETAILED DESCRIPTION

[0035] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings: Embodiment 1 refer to Figure 1-13 , an automatic production equipment for vacuum insulation panels, comprising: A frame 1, on which a long side finishing station 101, a long side gluing station 102, a long side folding station 103, an angle pinching station 104, a corner transition station 105, a short side gluing station 106, and a short side folding station 107 are arranged in sequence from the feeding end to the discharging end; The transmission mechanism 2, each station on the frame 1 is provided with a corresponding transmission mechanism 2, the transmission mechanism 2 transmits the vacuum insulation panel by belt conveyor; Gluing mechanism 3, the long side gluing station 102 and the short side gluing station 106 are both provided with corresponding gluing mechanism 3, which are used to apply glue to opposite sides of the upper surface of the vacuum insulation panel by spraying or coating; The folding mechanism 4, the long folding station 103 and the short folding station 107 are both provided with corresponding folding mechanisms 4, which are respectively used to fold and fix the redundant long sides and the redundant short sides of the vacuum insulation panel, and the folding mechanism 4 comprises a group of movably arranged flexible plates 402 and an electromagnetic suction component for controlling the setting position of the lower end of the flexible plate 402. After the flexible plate 402 moves and drives the redundant side to fold upward, the lower end of the flexible plate 402 abuts against the upper part of the folded redundant side for flattening; after the folding and flattening action is completed, the electromagnetic suction component is powered on and adsorbed to move the lower end of the flexible plate 402 upward and fix it, and the bending end of the flexible plate 402 is set at a distance from the upper end surface of the vacuum insulation panel; after the electromagnetic suction component is powered off, the flexible plate is reset by its own elastic force; Angle pinching mechanism 5, two of the conveying mechanisms 2 are arranged at the front and rear of the angle pinching station 104, and the discharge end of the front conveying mechanism 2 and the feed end of the rear conveying mechanism 2 are both provided with corresponding angle pinching mechanisms 5, and the angle pinching mechanism 5 comprises an angle pinching component 501 and a hot stamping component 502, and the angle pinching component 501 is used to push and fold the connection between the folded part of the redundant long side and the redundant short side of the vacuum insulation panel inward to form an angle pinch, and the hot stamping component 502 moves relative to the angle pinching component 501 to generate heat by friction for hot stamping and shaping of part of the redundant short side.

[0036] The folding mechanism 4 includes a group of mounting seats 401 that can be moved up and down and left and right and are arranged on both sides of the transmission mechanism 2. The flexible plate 402 can be replaced and fixedly installed under the corresponding mounting seat 401, and the flexible plate 402 is made of PU material; when the vacuum insulation panel is transmitted to the position, the flexible plate 402 is tilted on both sides of the redundant edge of the vacuum insulation panel, and the lower end of the flexible plate 402 is placed directly below the redundant edge; during the folding action, the flexible plate 402 moves up and relatively inward, and drives the redundant edge to fold inward until the flexible plate 402 is placed above the vacuum insulation panel and bent into a V shape, and the end of the flexible plate 402 is pressed above the folded redundant edge.

[0037] The electromagnetic suction component includes a plurality of electromagnets 404 evenly spaced and arranged through a mounting plate 403 fixedly connected to the mounting seat 401, and an iron part 405 corresponding one to the electromagnets 404 and fixed to the outer side surface of the lower end of the flexible plate 402 by bonding. When the electromagnet 404 is energized, it attracts the iron part 405 to move upward, and drives the lower end of the flexible plate 402 connected to the iron part 405 to move upward and then be fixed.

[0038] The present invention is used in the production process of redundant edge folding and shaping of vacuum insulation panels through the improved design of the operation process of long edge arrangement, long edge gluing, long edge folding, angle pinching, corner transition, short edge gluing, and short edge folding. The redundant long edges to be folded can be placed in a preliminary upright state through the arrangement of the long edges, which is convenient for improving the efficiency of the subsequent long edge folding. By gluing first and then folding, the redundant edges can be quickly shaped and fixed after folding. The folding mechanism, based on the folding process of imitating manual folding, uses a flexible plate 402 made of PU and other materials to push, fold, press and flatten the redundant edges, so as to promote the folded redundant edges to adhere flatly to the vacuum insulation panel. The flexible plate 402 itself has the dual characteristics of strength and flexibility, which can not only ensure that it is sufficient to flip the redundant edges upward during the folding action, but also can be used when the redundant edges are folded. Afterwards, it can form a reverse bend by itself, which can effectively avoid scratches or cuts caused by traditional rigid contact, and as it moves forward, the end is pressed and scraped flat to flatten the redundant edge after folding. Not only does it ensure that the folded edge is flattened, but the structure is significantly simplified, and the flexible plate can be cut and replaced at will according to the size of the equipment and the vacuum insulation board, which greatly improves the simplicity and reduces the equipment cost; and the flexible plate is a whole piece structure, which can be bent at will and quickly reset, effectively solving the problem that the traditional folding mechanism must be composed of multiple folding plates arranged side by side, and any folding plate will cause jamming if it is not folded, thereby improving the practical effect of the present invention. Furthermore, after completing the folding action, the folding mechanism needs to move up, retreat, rotate and reset, and move down before continuing the subsequent action. The present invention adds an electromagnetic suction component on the basis of the flexible board 402, and controls the setting position of the lower end of the flexible board 402 by whether the electromagnetic suction component is energized, thereby adjusting the bending of the flexible board 402 so that the distance between the bent end of the flexible board 402 and the upper end surface of the vacuum insulation board is set; after the folding mechanism is reset, the power is turned off, and the flexible board 402 is reset under the action of its own elasticity, the operation process is simpler and faster, the operation efficiency is improved, and its practical effect is ensured.

[0039] The angle pinching mechanism 5 comprises two groups of angle pinching components 501 which are symmetrically and synchronously driven and arranged on both sides of the transmission mechanism 2, the angle pinching components 501 comprising a positioning member 5011 for limiting the redundant long side to be folded, a flattening member 5012 which moves towards the positioning member 5011, and a pressing member 5013 which can move up and down and is arranged on the outside of the flattening member 5012, the end surface of the positioning member 5011 facing outward is arranged in a bevel shape; after the positioning member 5011 moves into position along the redundant short side to the connection between the redundant long side, the flattening member 5012 is pushed inwardly into position along the upper surface of the positioning member 5011, and pushes the redundant long side to move inwardly along the bevel of the positioning member 5011 to form an inwardly inclined bevel shape; after the positioning member 5011 is moved back and reset into position, the outer side surface of the flattening member 5012 is arranged at a distance from the end of the redundant short side of the vacuum insulation panel, so as to form a pressing area which is convenient for the pressing member 5013 to move down and fix the angle pinching.

[0040] The present invention realizes the angle pinching action by improving the coordination of the positioning member 5011, the flattening member 5012 and the pressing member 5013, etc., and uses the positioning member 5011 to flatten the redundant short side, and forms the positioning through the inclined surface end of the positioning member 5011, and then when the flattening member 5012 is pushed inwardly along the upper surface of the positioning member 5011, the redundant long side is pushed inwardly along the inclined surface of the positioning member 5011 to form an inwardly inclined inclined side, forming an inward folding; and after the positioning member 5011 is moved back and reset to the position, the outer side surface of the flattening member 5012 and the redundant short side end of the vacuum insulation panel are spaced apart to form a pressing area that is convenient for the pressing member 5013 to move down and fix the angle pinching, and then the pressing member 5013 is moved down to press and fix the folded corner part to form a fold line. The angle pinching structure of the present invention is simpler, the operation method is simpler, and it is easier to implement, thereby improving the efficiency of angle pinching.

[0041] The hot stamping component 502 is installed below the positioning member 5011 and generates heat by friction as it moves relative to the positioning member 5011; the positioning member 5011 includes an L-shaped plate 5131 with an inclined end face, and a guide plate 5132 with a triangular structure is fixedly connected to the side of the L-shaped plate 5131 facing the vacuum insulation panel; the hot stamping component 502 includes a hot stamping plate 5021 that can be relatively moved and fitted on the bottom surface of the L-shaped plate 5131; when the L-shaped plate 5131 is located on the redundant short side and moves left and right, the hot stamping plate 5021 moves relative to the L-shaped plate 5131 and generates heat by friction to form hot stamping for part of the redundant short side.

[0042] The L-shaped plate 5131 includes a pressing portion with an inclined front end and a mounting portion extending backward, and a long hole 6 penetrating the upper and lower end surfaces is provided in the middle position of the mounting portion. At least one positioning seat 5022 penetrating the long hole 6 is fixedly connected to the hot stamping plate 5021, and the hot stamping plate 5021 can be limitedly fitted and movably installed under the L-shaped plate 5131 by cooperating with the shaft and slider 5023 provided on both sides of the positioning seat 5022 and the guide groove concavely provided on the L-shaped plate 5131; the L-shaped plate 5131 is provided with a fixing block on both sides of the long hole 6. A corresponding elastic member 5024 is installed, and the end portion of the elastic member 5024 is fixedly connected to the slider 5023 adjacent to it. The outer end portion of the hot stamping plate 5021 protrudes from the L-shaped plate 5131 and its end face is arranged in an inclined surface. A corresponding positioning member 5025 is fixedly connected to the lower side of the other side of the L-shaped plate 5131 where no inclined surface is arranged. When the pressing member 5013 moves toward the outside of the redundant short side, the hot stamping plate 5021 moves in the opposite direction under the action of the interaction force. After moving into position and being blocked by the positioning member 5025, its end portion is flush with the end portion of the L-shaped plate 5131, and the elastic member 5024 is stretched.

[0043] The action of pinching the corner affects the quality of the subsequent short folded edge and whether the redundant edge will bulge, so the quality of pinching the corner needs to be ensured, and the flatness of the redundant short edge will affect the action of the flattening member 5012. On this basis, a hot stamping component 502 is added to the positioning member 5011, and the hot stamping component 502 moves with the positioning member 5011 to perform hot stamping and flattening on the redundant short edge. However, due to the limitation of the setting position, it is not easy to install the traditional hot stamping equipment at this position, and the lines connected to the traditional hot stamping equipment will affect the movement of the positioning member 5011. Therefore, the present invention sets a hot stamping plate 5021 that can be relatively moved and attached to the bottom surface of the L-shaped plate of the positioning member 5011. The left and right movement of the positioning member 5011 drives the hot stamping plate 5021 to move relatively and generate heat by friction. While the positioning member 5011 flattens the redundant short edge, it generates heat by friction and hot stamping to flatten the redundant short edge. The hot ironing plate 5021 is connected to the positioning member 5011 by means of a slider 5023 and a guide groove, and the end of the hot ironing plate 5021 protrudes from the positioning member 5011. During the angle pinching action, the hot ironing plate 5021 moves in the opposite direction to the positioning member 5011 under the action of the mutual force and is blocked by the positioning member. When the positioning member 5011 is reset, the hot ironing plate 5021 moves toward each other and resets under the dual action of the mutual force and the elastic force of the elastic member to continue to generate heat by friction, thereby ensuring that the temperature of the hot ironing plate 5021 is maintained at 35-50°C, ensuring the hot ironing effect and the practical effect of the present invention.

[0047] Embodiment 2 The difference between this embodiment and the first embodiment is that the hot stamping plate 5021 is made of die steel and is processed by rusting and grinding in sequence until smooth and evenly distributed pits are formed on its surface.

[0048] The hot stamping plate 5021 of the present invention is made of mold steel, and preferably model H13 mold steel, which has high wear resistance and fast thermal conductivity. After rust treatment, it is polished until its surface is flat and evenly distributed with pits, so that the surface of the hot stamping plate 5021 is not only smooth and flat to ensure that the hot stamping plate 5021 and the positioning member 5011 can move relative to each other, but also can increase the friction coefficient of the hot stamping plate 5021, thereby increasing the friction heat generation temperature, ensuring the practical effect of self-heating of the hot stamping component 502, achieving hot stamping and flattening of redundant short edges, and promoting the completion of the angle pinching action.
