Description

Technical Field

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

[0002] Vacuum insulation panel is a kind of vacuum thermal insulation material, which is composed of a filled core material and a vacuum protection surface layer. It can effectively avoid heat transfer caused by air convection, greatly reducing the thermal conductivity coefficient. It is mainly used in various cold chain equipment such as refrigerators, freezers, refrigerated trucks, cold storages, etc., as well as the external wall insulation systems of various buildings such as residences, 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 conservation requirements, its application is becoming more and more extensive.

[0003] After the filled core material and the vacuum protection surface layer are compounded, redundant edges will be generated around them. It is necessary to fold the redundant edges by bending and pressing them flat on the top of the vacuum insulation panel to ensure the use of the vacuum insulation panel. Traditionally, there are mainly two methods for folding the edges of vacuum insulation panels: one is manual edge folding, but its production efficiency is low, the work intensity is high, the product manufacturing cost is high, and the quality is unstable; the other is to use automated equipment for processing to solve the labor cost, improve the efficiency and quality. However, the existing automated equipment has a complex structure, and the operation processes of each station are also complex. For example, it is necessary to use a continuous edge press to first bend and press the redundant long edge flat and then fix it with tape. However, once the middle part of the continuous edge press gets stuck, it must be stopped for repair, affecting the production progress; secondly, the existing edge folding mechanisms all imitate the process of manual folding. The driving mechanism drives up and down and left and right, driving a number of edge folding plates arranged side by side to move, folding the redundant edges of the vacuum insulation panel upward and inward, and then making it rotate in the reverse direction through the structure of the edge folding plate. As the edge folding plate moves, its lower end scrapes across the redundant edge, thereby folding and pressing the redundant edge. However, the edge folding plate not only has a complex connection structure, but also once its rotation gets stuck, the entire edge folding equipment will get stuck and stop, and its operation process is more cumbersome, and the efficiency stagnates; furthermore, the corner pinching mechanism pinches the corner by inlaying and folding the height connection part of the long folded edge and the short folded edge. However, it has a high requirement for the flatness of the height connection part, otherwise it will cause the bending to gather at the corner pinching position and affect the quality of the subsequent short edge 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, a simple operation process and easy implementation. Summary of the Invention

[0005] In view of the above technical problems existing in the prior art, the present invention provides an automatic production equipment for vacuum insulation panels, which can effectively solve the technical problems existing in the above prior art.

[0006] The technical solution of the present invention is as follows:

[0007] An automatic production equipment for vacuum insulation panels, comprising:

[0008] A frame, on which a long-edge sorting station, a long-edge gluing station, a long-edge folding station, a corner pinching station, a corner transition station, a short-edge gluing station, and a short-edge folding station are sequentially arranged from the feeding end to the discharging end;

[0009] A transmission mechanism, corresponding transmission mechanisms are arranged at each station on the frame, and the transmission mechanism transports the vacuum insulation panel by means of belt transmission;

[0010] A gluing mechanism, corresponding gluing mechanisms are arranged at the long-edge gluing station and the short-edge gluing station, and are respectively used for applying glue to the opposite sides of the upper surface of the vacuum insulation panel by means of spraying or coating;

[0011] A folding mechanism, corresponding folding mechanisms are arranged at the long-edge folding station and the short-edge folding station, and are respectively used for folding and fixing the redundant long edges and redundant short edges of the vacuum insulation panel. The folding mechanism includes a group of flexibly arranged plates that move and an electromagnetic suction component for controlling the setting position of the lower end of the flexibly arranged plate. After the flexibly arranged plate moves and drives the redundant edge to be folded upward, the lower end of the flexibly arranged plate abuts above the folded redundant edge for scraping. After the folding and scraping action is completed, the lower end of the flexibly arranged plate is fixed by energizing and adsorbing the electromagnetic suction component, and the distance between the bent end of the flexibly arranged plate and the upper end surface of the vacuum insulation panel is set. After the electromagnetic suction component is powered off, the flexibly arranged plate resets by its own elastic force;

[0012] A corner pinching mechanism, two transmission mechanisms are arranged front and back at the corner pinching station, and corresponding corner pinching mechanisms are arranged at the discharging end of the front transmission mechanism and the feeding end of the rear transmission mechanism. The corner pinching mechanism includes a corner pinching component and a hot ironing component. The corner pinching component is used for pushing and folding inward the connection part between the folded part of the redundant long edge and the redundant short edge of the vacuum insulation panel to form a pinched corner, and the hot ironing component moves relative to the corner pinching component to generate heat by friction for hot ironing and shaping part of the redundant short edge.

[0013] The folding mechanism includes a group of mounting seats that can move up and down and left and right on both sides of the transmission mechanism. The flexibly arranged plate can be fixedly installed below the corresponding mounting seat, and the flexibly arranged plate is made of PU material. When the vacuum insulation panel is transported in place, the flexibly arranged plate is inclined on both sides of the redundant edge of the vacuum insulation panel, and the lower end of the flexibly arranged plate is placed directly below the redundant edge. During the folding action, the flexibly arranged plate moves upward and inward relatively, and drives the redundant edge to be folded inward until the flexibly arranged plate is placed above the vacuum insulation panel and bent into a V shape, and then the end part of the flexibly arranged plate is pressed on the folded redundant edge.

[0014] The electromagnetic suction assembly includes a plurality of electromagnets that are evenly distributed at equal intervals through a mounting plate fixed on the mounting base, and iron parts that correspond to the electromagnets one by one and are fixedly installed on the outer side of the lower end of the flexible plate by an adhesive method. When the electromagnets are energized, they adsorb the iron parts to move upward, and drive the lower end of the flexible plate connected to the iron parts to move upward and then be fixed.

[0015] The corner pinching mechanism includes two groups of symmetric and synchronously driven corner pinching components arranged on both sides of the transmission mechanism. The corner pinching component includes a positioning member one for limiting the redundant long side to be folded, a flattening member that moves towards the positioning member one, and a pressing member that can move up and down on the outside of the flattening member. The end face of the positioning member one facing the outside is arranged in an inclined shape; after the positioning member one moves to the connection of the redundant short side and the redundant long side, the flattening member pushes inward along the upper surface of the positioning member one to the in-place position, and pushes the redundant long side to move inward along the inclined surface of the positioning member one to form an inwardly inclined hypotenuse shape; after the positioning member one moves back to the reset position, the outer side of the flattening member is spaced from the end of the redundant short side of the vacuum insulation panel to form a pressing area that facilitates the pressing member to move down to fix the corner.

[0016] The hot stamping assembly is installed below the positioning member one and generates heat by friction as it moves relatively with the positioning member one; the positioning member one includes an L-shaped plate with an inclined end face, and a triangular guide plate is fixedly connected to one side of the L-shaped plate facing the vacuum insulation panel; the hot stamping assembly includes a hot stamping plate that can be relatively movably and fittingly installed on the bottom surface of the L-shaped plate; when the L-shaped plate moves left and right on the redundant short side, the hot stamping plate moves relatively with the L-shaped plate and generates heat by friction to form hot stamping and shaping for part of the redundant short side.

[0017] The L-shaped plate includes a pressing portion with an inclined front end and an installation portion extending backward. A long hole penetrating through the upper and lower end faces is arranged at the middle position of the installation portion. At least one positioning seat penetrating through the long hole is fixedly connected to the hot stamping plate. The hot stamping plate is movably and fittingly installed under the L-shaped plate in a limited manner by cooperating with the guide grooves recessed in the L-shaped plate through shaft parts and sliders arranged on both sides of the positioning seat; elastic members are installed on both sides of the long hole on the L-shaped plate through fixing blocks, and the end parts of the elastic members are fixedly connected to the adjacent sliders. The outer end of the hot stamping plate protrudes from the L-shaped plate and its end face is arranged in an inclined shape. A corresponding positioning member two is fixedly connected below the other side of the L-shaped plate without an inclined surface; when the pressing member moves outward to the redundant short side, the hot stamping plate moves in the opposite direction under the action of the mutual force. After moving to the in-place position and being blocked by the positioning member two, its end is flush with the end of the L-shaped plate, and the elastic member is stretched.

[0018] The hot ironing plate is made of die steel and is processed by rusting and polishing in sequence to form smooth and evenly distributed pits on its surface.

[0019] A corresponding finishing mechanism is provided at the long-side finishing station at the feeding end of the frame for finishing the redundant long sides of the vacuum insulation panel into an upright state; the finishing mechanism includes a set of V-shaped guide plates symmetrically installed on both sides of the transmission mechanism, and the V-shaped guide plate includes a lower end portion in an upright state and an upper end portion integrally formed and inclined outward.

[0020] The transmission mechanism at the short-side gluing station is arranged at a 90° angle to the transmission mechanism at the corner pinching station. A reversing mechanism for 90° converting the transmission direction of the vacuum insulation panel is provided at the corner transition station. The reversing mechanism includes a rotatably arranged roller assembly, a positioning push plate in the transmission direction of the corner pinching station, and a reversing push plate in the transmission direction of the short-side gluing station.

[0021] A support assembly for supporting the operation of the corner pinching mechanism is further provided below the corner pinching mechanism. The support assembly includes a set of support rods swingably arranged in the middle of the transmission mechanism and a set of support seats movably installed up and down on both sides of the transmission mechanism; when the vacuum insulation panel moves in place, the support rods rotate and stand upright below the redundant short side for supporting and limiting the first positioning member; the support seats move up and are placed below the redundant short side for supporting the flattening member and the pressing member; at the corner pinching station, pressing blocks for fixing the vacuum insulation panel are movably arranged left and right on both sides of the transmission mechanism, and scraping plates are installed above the pressing blocks and movable up and down and left and right.

[0022] Advantages of the present invention:

[0023] 1) Through the improved design of the operation process of long-edge sorting, long-edge gluing, long-edge folding, corner pinching, corner transition, short-edge gluing, and short-edge folding, it is used in the production process of redundant-edge folding and shaping of vacuum insulation panels. Through long-edge sorting, the redundant long edge to be folded can be in a preliminary upright state, which is convenient for improving the efficiency of subsequent long-edge folding. By gluing first and then folding, the redundant edge can be quickly shaped and fixed after folding. On the basis of imitating the flipping process of manual folding, the folding mechanism uses a flexible plate made of materials such as PU to push, flip, and press and scrape the redundant edge, promoting the smoothly adhered redundant edge on the vacuum insulation panel; by taking advantage of the dual characteristics of the flexible plate itself, which has both strength and flexibility, it can not only ensure sufficient force to flip the redundant edge upward during the folding action, but also form a reverse bend by itself after the redundant edge is flipped, effectively avoiding scratches or cuts caused by traditional rigid contact. As it moves forward, the end presses and scrapes the folded redundant edge, not only significantly simplifying the structure while ensuring the folding and scraping are smooth, but also the flexible plate can be arbitrarily cut and replaced according to the size of the equipment and the vacuum insulation panel, greatly improving simplicity and reducing equipment costs; moreover, the flexible plate is a whole-piece structure, which can be arbitrarily bent and quickly reset, effectively solving the problems that the traditional folding mechanism must be composed of multiple side-by-side folding plates and jamming will occur if any folding plate fails to flip, improving the practical effect of the present invention;

[0024] Furthermore, after the folding mechanism completes the folding action, it needs to go through processes such as upward movement, backward movement, rotational reset, and downward movement before it can continue subsequent actions. The present invention adds an electromagnetic suction component on the basis of the flexible plate. By controlling the energization or de-energization of the electromagnetic suction component, the setting position of the lower end of the flexible plate is controlled, and then the bending of the flexible plate is adjusted so that the distance between the bent end of the flexible plate and the upper end surface of the vacuum insulation panel is set; after the folding mechanism is reset, the power is cut off, and the flexible plate resets under its own elastic action. The operation process is more simple and fast, improving the operation efficiency and ensuring its practical effect. And bonding an iron piece on the outer side of the lower end of the flexible plate will not only not affect the bending of the flexible plate, but more importantly, it can locally increase the weight of its lower end to improve the effect of the flexible plate scraping the redundant edge and the efficiency of its own reset.

[0025] 2) By improving the cooperation of components such as the first positioning member, the flattening member, and the pressing member, the present invention realizes the corner pinching action. The first positioning member is used to flatten the redundant short side, and positioning is formed through the inclined end portion on the first positioning member. Then, when the flattening member is pushed inward along the upper surface of the first positioning member to the in-place position, the redundant long side is pushed to move inward along the inclined surface of the first positioning member to form an inwardly inclined hypotenuse shape, resulting in inward folding. After the first positioning member moves backward and resets to the in-place position, the distance between the outer side surface of the flattening member and the end portion of the redundant short side of the vacuum insulation panel is set to form a pressing area convenient for the pressing member to move downward to fix the corner pinch. Then, the pressing member moves downward to press and fix the folded corner portion to form a folding line. The corner pinching structure of the present invention is simpler, the operation method is more convenient, and it is easier to implement, thereby improving the efficiency of corner pinching.

[0026] 3) The corner pinching action affects the quality of the subsequent short folded edge and the problem of whether the redundant edge will protrude. Therefore, it is necessary to ensure the quality of corner pinching. The flatness of the redundant short side affects the action of the flattening member. On this basis, a hot stamping component is added to the first positioning member. The hot stamping component moves with the first positioning member to hot stamp and flatten the redundant short side. However, due to the limitation of the installation 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 first positioning member. Therefore, the present invention provides a hot stamping plate that can move relatively and fit on the bottom surface of the L-shaped plate of the positioning member. By the left and right movement of the first positioning member, the hot stamping plate is driven to move relatively and generate heat by friction. While the first positioning member flattens the redundant short side, the redundant short side is hot stamped and flattened by the heat generated by friction. The hot stamping plate is connected to the first positioning member to move relatively through the cooperation of a slider and a guide groove, and the end portion of the hot stamping plate protrudes from the first positioning member. During the corner pinching action, the hot stamping plate moves in the opposite direction to the first positioning member under the action of the interaction force and is blocked by the first positioning member. When the first positioning member resets, the hot stamping plate moves in the opposite direction and resets under the dual action of the interaction force and the elastic force of the elastic member to continue generating heat by friction, thereby ensuring that the temperature of the hot stamping plate remains at 35-50°C, ensuring the hot stamping effect and the practical effect of the present invention.

[0027] 4) The hot stamping plate of the present invention is made of die steel material, and the die steel of model H13 is preferably used. It has high wear resistance and fast heat conduction performance. After being rust-treated and polished until its surface is flat and evenly distributed with pits, the surface of the hot stamping plate not only has smooth flatness to ensure that the hot stamping plate and the first positioning member can move relatively, but also can increase the friction coefficient of the hot stamping plate, thereby increasing the temperature generated by friction, ensuring the practical effect of the self-heating of the hot stamping component, realizing the hot stamping and flattening of the redundant short side, and promoting the completion of the corner pinching action.

Detailed implementation mode

[0043] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in combination with the attached drawings:

[0044] Embodiment 1

[0045] Reference Figure 1-13 , an automatic production equipment for vacuum insulation panels, comprising:

[0046] Frame 1, on which there are successively arranged a long-edge sorting station 101, a long-edge gluing station 102, a long-edge folding station 103, a corner pinching station 104, a corner transition station 105, a short-edge gluing station 106, and a short-edge folding station 107 from the feeding end to the discharging end;

[0047] Transmission mechanism 2, corresponding transmission mechanisms 2 are arranged at each station on the frame 1, and the transmission mechanism 2 conveys the vacuum insulation panel by means of belt transmission;

[0048] Gluing mechanism 3, corresponding gluing mechanisms 3 are arranged at the long-edge gluing station 102 and the short-edge gluing station 106, and are respectively used for applying glue to the opposite sides of the upper surface of the vacuum insulation panel by means of spraying glue or coating glue;

[0049] The hemming mechanism 4, corresponding hemming mechanisms 4 are provided on both the long hemming station 103 and the short hemming station 107, which are respectively used to fold and fix the redundant long side and the redundant short side of the vacuum insulation panel. The hemming mechanism 4 includes a set of flexibly arranged flexible plates 402 and an electromagnetic suction assembly 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 above the folded redundant side for scraping; after the hemming and scraping action is completed, the lower end of the flexible plate 402 is fixed by energizing and adsorbing the electromagnetic suction assembly, and the distance between the bent end of the flexible plate 402 and the upper end face of the vacuum insulation panel is set; after the electromagnetic suction assembly is powered off, the flexible plate resets by its own elastic force;

[0050] The corner pinching mechanism 5, two of the transfer mechanisms 2 are arranged front and back on the corner pinching station 104, and corresponding corner pinching mechanisms 5 are provided at the discharge end of the front transfer mechanism 2 and the feed end of the rear transfer mechanism 2. The corner pinching mechanism 5 includes a corner pinching assembly 501 and a heat ironing assembly 502. The corner pinching assembly 501 is used to push and fold inward the connection between the folded part of the redundant long side and the redundant short side of the vacuum insulation panel to form a pinched corner, and the heat ironing assembly 502 moves relative to the corner pinching assembly 501 to generate heat by friction for heat ironing and shaping part of the redundant short side.

[0051] The hemming mechanism 4 includes a set of mounting seats 401 that can move up and down and left and right on both sides of the transfer mechanism 2. The flexible plate 402 can be fixedly installed below the corresponding mounting seat 401. The flexible plate 402 is made of PU material; when the vacuum insulation panel is transported in place, the flexible plate 402 is inclined on both sides of the redundant side of the vacuum insulation panel, and the lower end of the flexible plate 402 is placed directly below the redundant side; during the hemming action, the flexible plate 402 moves upward and inward relatively, and drives the redundant side 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 side.

[0052] The electromagnetic suction assembly includes a plurality of electromagnets 404 evenly arranged at equal intervals through a mounting plate 403 fixed on the mounting seat 401, and iron parts 405 corresponding to the electromagnets 404 one by one and fixedly installed on the outer side of the lower end of the flexible plate 402 by bonding. When the electromagnet 404 is energized, it adsorbs 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.

[0053] Through the improved design of the operation process of long-edge sorting, long-edge gluing, long-edge folding, corner pinching, corner transition, short-edge gluing, and short-edge folding, it is used in the production process of redundant-edge folding and shaping of vacuum insulation panels. Through long-edge sorting, the redundant long edge to be folded can be in a preliminary upright state, which is convenient for improving the efficiency of subsequent long-edge folding. By gluing first and then folding, the redundant edge can be quickly fixed in shape after folding. On the basis of imitating the folding process of manual folding, the folding mechanism uses a flexible plate 402 made of materials such as PU to push, fold, and press and scrape the redundant edge, promoting the flat adhesion of the folded redundant edge on the vacuum insulation panel; by taking advantage of the dual characteristics of the flexible plate 402 itself, which has both strength and flexibility, it can not only ensure that it is sufficient to push the redundant edge to turn upward during the folding action, but also form a reverse bend by itself after the redundant edge is folded, effectively avoiding scratches or cuts caused by traditional rigid contact, and pressing and scraping the folded redundant edge at the end as it moves forward. Not only is the folding and scraping ensured, but the structure is significantly simplified, and the flexible plate can be arbitrarily cut and replaced according to the size of the equipment and the vacuum insulation panel, greatly improving simplicity and reducing equipment costs; moreover, the flexible plate is a whole-piece structure, which can be arbitrarily bent and quickly reset, effectively solving the problems that the traditional folding mechanism must be composed of multiple side-by-side folding plates and jamming will occur if any folding plate fails to fold, improving the practical effect of the present invention. Furthermore, after the folding mechanism completes the folding action, it needs to move up, retreat, rotate and reset, and move down and other processes before it can continue the subsequent actions. The present invention adds an electromagnetic suction component on the basis of the flexible plate 402, controls the setting position of the lower end of the flexible plate 402 by energizing or de-energizing the electromagnetic suction component, and then adjusts the bending of the flexible plate 402 so that the distance between the bent end of the flexible plate 402 and the upper end surface of the vacuum insulation panel is set; after the folding mechanism is reset, the power is cut off, and the flexible plate 402 resets under its own elastic action, making the operation process more simple and fast, improving the operation efficiency, and ensuring its practical effect.

[0054] The corner pinching mechanism 5 includes two groups of symmetrically and synchronously driven corner pinching components 501 arranged on both sides of the transmission mechanism 2. The corner pinching component 501 includes a first positioning member 5011 for limiting the redundant long side to be folded, a flattening member 5012 that moves towards the first positioning member 5011, and a pressing member 5013 that is movably arranged up and down outside the flattening member 5012. The end face of the first positioning member 5011 facing the outside is arranged in an inclined plane shape; after the first positioning member 5011 moves along the redundant short side to the connection of the redundant long side in place, the flattening member 5012 is pushed inward along the upper surface of the first positioning member 5011 in place, and the redundant long side is pushed to move inward along the inclined plane of the first positioning member 5011 to form an inwardly inclined hypotenuse shape; after the first positioning member 5011 moves backward and resets in place, the outer side surface of the flattening member 5012 is set at a distance from the end of the redundant short side of the vacuum insulation panel to form a pressing area convenient for the pressing member 5013 to move downward to fix the corner pinch.

[0055] In the present invention, through the improved design of the cooperation of various components such as the first positioning member 5011, the flattening member 5012, and the pressing member 5013, the corner pinching action is realized. The first positioning member 5011 is used to flatten the redundant short side, and positioning is formed through the inclined plane-shaped end on the first positioning member 5011. Then, when the flattening member 5012 is pushed inward along the upper surface of the first positioning member 5011 in place, the redundant long side is pushed to move inward along the inclined plane of the first positioning member 5011 to form an inwardly inclined hypotenuse shape, forming an inward fold; and after the first positioning member 5011 moves backward and resets in place, the outer side surface of the flattening member 5012 is set at a distance from the end of the redundant short side of the vacuum insulation panel to form a pressing area convenient for the pressing member 5013 to move downward to fix the corner pinch. Then, the pressing member 5013 is moved downward to press and fix the folded corner part to form a folding line. The corner pinching structure of the present invention is simpler, the operation method is more convenient, and it is easier to implement, thereby improving the efficiency of corner pinching.

[0056] The hot stamping component 502 is installed below the first positioning member 5011 and generates heat by relative movement and friction with the first positioning member 5011; the first positioning member 5011 includes an L-shaped plate 5131 with an inclined plane-shaped end face, and a guiding plate 5132 with a triangular structure is fixedly connected to one 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 movably attached and installed on the bottom surface of the L-shaped plate 5131; when the L-shaped plate 5131 moves left and right on the redundant short side, the hot stamping plate 5021 moves relatively with the L-shaped plate 5131 and generates heat by friction to form hot stamping and shaping on part of the redundant short side.

[0057] The L-shaped plate 5131 includes a pressing portion with an inclined front end and an installation portion extending backward. A long hole 6 penetrating the upper and lower end faces is provided at the middle position of the installation portion. At least one positioning seat 5022 penetrating the long hole 6 is fixedly connected to the hot ironing plate 5021. The hot ironing plate 5021 is movably installed in a limited and fitted manner below the L-shaped plate 5131 by means of shaft members and sliders 5023 disposed on both sides of the positioning seat 5022 and cooperating with a guide groove recessed in the L-shaped plate 5131. Elastic members 5024 are installed on both sides of the long hole 6 on the L-shaped plate 5131 through fixing blocks. The end portions of the elastic members 5024 are fixedly connected to the adjacent sliders 5023. The outer end portion of the hot ironing plate 5021 protrudes from the L-shaped plate 5131 and its end face is inclined. A corresponding positioning member two 5025 is fixedly connected below the other side of the L-shaped plate 5131 without an inclined surface. When the pressing member 5013 moves outward to the redundant short side, the hot ironing plate 5021 moves in the opposite direction under the action of the mutual force. After moving in place and being blocked by the positioning member two 5025, its end is flush with the end of the L-shaped plate 5131, and the elastic member 5024 is stretched.

[0058] The pinching angle action affects the quality of the subsequent short folded edge and the problem of whether the redundant edge will protrude. Therefore, it is necessary to ensure the quality of the pinching angle. The flatness of the redundant short side will affect the action of the flattening member 5012. On this basis, a hot ironing assembly 502 is added to the positioning member one 5011. The hot ironing assembly 502 moves with the positioning member one 5011 to hot iron and flatten the redundant short side. However, due to the limitation of the installation position, it is not easy to install a traditional hot ironing device at this position, and the lines connected to the traditional hot ironing device will affect the movement of the positioning member one 5011. Therefore, the present invention provides a hot ironing plate 5021 that can be relatively movably fitted to the bottom surface of the L-shaped plate of the positioning member one 5011. By using the left and right movement of the positioning member one 5011, the hot ironing plate 5021 is driven to move relatively and generate heat by friction. While the positioning member one 5011 flattens the redundant short side, the redundant short side is hot ironed and flattened by the heat generated by friction. The hot ironing plate 5021 is relatively movably connected to the positioning member one 5011 by means of the cooperation of the slider 5023 and the guide groove. The end portion of the hot ironing plate 5021 protrudes from the positioning member one 5011. During the pinching angle action, the hot ironing plate 5021 moves in the opposite direction to the positioning member one 5011 under the action of the mutual force and is blocked by the positioning member. When the positioning member one 5011 is reset, the hot ironing plate 5021 moves in the opposite direction and is reset under the dual action of the mutual force and the elastic force of the elastic member to continue generating 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.

[0060] The transmission mechanism 2 at the short-side gluing station 106 is arranged at a 90° angle to the transmission mechanism 2 at the corner pinching station 104. A reversing mechanism 8 for 90° converting the transmission direction of the vacuum insulation panel is provided at the corner transition station 105. The reversing mechanism 8 includes a rotatably arranged roller assembly, a positioning push plate 801 in the transmission direction of the corner pinching station 104, and a reversing push plate 802 in the transmission direction of the short-side gluing station 106.

The support assembly 503 includes a set of support rods 5031 swingably arranged in the middle of the transmission mechanism 2 and a set of support seats 5032 movably installed up and down on both sides of the transmission mechanism 2; when the vacuum insulation panel moves into place, the support rods 5031 rotate and stand upright under the redundant short side for supporting and limiting the first positioning member 5011; the support seats 5032 move upward and are placed under the redundant short side for supporting the flattening member 5012 and the pressing member 5013; at the corner pinching station 104, pressing blocks 504 for fixing the vacuum insulation panel are movably arranged left and right on both sides of the transmission mechanism 2, and scraping plates 505 are installed above the pressing blocks 504 and movable up, down, left, and right.

[0062] Embodiment 2

[0063] The difference between this embodiment and Embodiment 1 is that the hot ironing plate 5021 is made of die steel and is processed by rusting and grinding in sequence until its surface forms smooth and evenly distributed pits.

[0064] The hot ironing plate 5021 of the present invention is made of die steel, and preferably die steel of model H13. It has high wear resistance and fast heat conduction performance. After rusting treatment, it is polished until its surface is flat and evenly distributed with pits, so that the surface of the hot ironing plate 5021 not only has smooth flatness to ensure the relative movement between the hot ironing plate 5021 and the first positioning member 5011, but also can increase the friction coefficient of the hot ironing plate 5021, thereby increasing the temperature generated by friction, ensuring the practical effect of self-heating of the hot ironing assembly 502, realizing the hot ironing and flattening of the redundant short side, and promoting the completion of the corner pinching action.

[0065] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of Embodiment 1. For the sake of brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding content in Embodiment 1.

[0066] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
