Description

Technical Field

[0001] The present invention relates to the technical field of vacuum insulation panel production equipment, and specifically refers to a highly adaptable vacuum insulation panel edge folding device. 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. It is mainly used in various cold chain equipment such as refrigerators, freezers, refrigerated trucks, cold storages, and 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 increasing requirements for environmental protection and energy conservation in the world, 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 and press the redundant edges flat above the vacuum insulation panel by folding to ensure the use of the vacuum insulation panel. Traditionally, there are mainly two ways to fold 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 and improve efficiency and quality. However, the existing automated equipment has a complex structure and a complex operation process. Among them, the process of folding the long edge in the vacuum insulation panel edge folding process takes the longest time. The existing edge folding mechanisms all imitate the process of manual folding. The driving mechanism drives up and down and left and right to drive a plurality of edge folding plates arranged side by side to move, turning the redundant edge of the vacuum insulation panel upward and inward, and then making it rotate reversely through the structure of the edge folding plate. As the lower end of the edge folding plate scrapes across the redundant edge when it moves, the redundant edge is then folded and pressed. And at present, most edge folding equipment needs the product to pause before folding the long edge of the vacuum insulation panel. It not only has a complex structure, but also has a cumbersome operation process and stagnant efficiency.

[0004] Therefore, the research purpose of the present invention is to design a highly adaptable vacuum insulation panel edge folding device with a simple structure and operation process, which can complete smooth edge folding without pausing the product. Summary of the Invention

[0005] In view of the above technical problems existing in the prior art, the present invention provides a highly adaptable vacuum insulation panel edge folding device, which can effectively solve the above technical problems existing in the prior art.

[0006] The technical solution of the present invention is as follows: A highly adaptable vacuum insulation panel edge folding device, comprising: A frame, A transmission mechanism, installed on the frame and transmitting the vacuum insulation panel by belt transmission; Side pressing mechanism, installed on both sides of the transmission mechanism and movable left and right, used to correct and align the vacuum insulation panel and fit and stand the long side leaves on its side. Guiding and folding mechanism, including two guiding belts arranged on both sides of the transmission mechanism. A driving roller and a driven roller driven by corresponding driving motors are respectively connected in front of and behind the guiding belt. Through the cooperation and guidance of the driving roller and the driven roller, the front end of the guiding belt is set to be upright and the rear end is set to be horizontal for torsion. Deviation correction mechanism, including deviation correction blocks evenly fixed on the inner side surface of the guiding belt by bonding, and embedding grooves evenly embedded on the circumferential surfaces of the driving roller and the driven roller respectively. The shapes of the deviation correction blocks and the embedding grooves are arc-shaped surfaces that are adapted to each other. When the driving roller and the driven roller cooperate to drive the guiding belt to transmit, the deviation correction blocks and the embedding grooves are engaged with each other in sequence one by one to perform self-correction of the guiding belt. Heat conduction mechanism, used to evenly transfer the heat generated by friction when the deviation correction mechanism is transmitted along with the guiding belt to the guiding belt, so as to conduct heat through the guiding belt to thermally iron and shape the folded long side leaves. Wide pressing belt mechanism, installed above the transmission mechanism and cooperating with the transmission mechanism to press the vacuum insulation panel so that the folded long side leaves are adhesively connected to the vacuum insulation panel.

[0007] The hemming device further includes: Gluing mechanism, used to apply glue to the relative two sides of the upper surface of the vacuum insulation panel by spraying or coating, installed between the side pressing mechanism and the guiding and folding mechanism. Pressing plate mechanism, installed at the front end of the gluing mechanism and inside the side pressing mechanism, including two pressing belts driven to move up and down by corresponding first lifting components respectively, and the pressing belts are driven to transmit by corresponding power motors. The guiding and adjusting mechanism includes a plurality of iron parts that are evenly distributed at intervals in the front and rear direction and are installed in an inclined hinged manner on the outer side wall of the pressing plate belt through corresponding small-stiffness springs for limiting, and small magnets fixedly installed on the pressing plate belt corresponding to the iron parts one by one. The iron parts are arranged on the side of the pressing plate belt facing the side pressing mechanism. After the pressing plate mechanism moves downward and presses on the upper side of the vacuum insulation panel, the iron parts are pressed until their outer surfaces are flush with the outer surface of the pressing plate belt, and the iron parts are adsorbed and fixed by the small magnets, and the small-stiffness springs are compressed. The guiding and adjusting mechanism further includes a large magnet installed at intervals at the front end of the pressing plate belt. The magnetic force of the large magnet is greater than that of the small magnet. When the pressing plate belt drives the iron parts to the relative position of the large magnet, the iron parts are inclined downward under the cooperation of the magnetic attraction of the large magnet and the elastic force of the small-stiffness springs, and the iron parts are out of the magnetic attraction range of the small magnets.

[0008] The side pressing mechanism includes two side pressing belts respectively driven by corresponding driving motors. The side pressing belts are driven by a two-dimensional motion mechanism fixedly installed on the frame. The two-dimensional motion mechanism includes a fixed guide rail horizontally arranged on the frame. A moving seat driven by a corresponding driving cylinder is movably installed on the fixed guide rail. The side pressing belts are installed on the moving seat. A compensation component for compensating the width deviation of the vacuum insulation panel is arranged between the moving seat and the driving cylinder. The compensation component includes a group of connecting plates respectively fixed to the end parts of the moving seat and the piston rod of the driving cylinder, and a corresponding compression spring is connected and installed between the two connecting plates.

[0009] The center lines of the driving roller and the driven roller are in a vertical state, that is, the driving roller is vertically arranged and the driven roller is horizontally arranged. The distance between the two driven rollers is less than the distance between the two driving rollers. The inner end part of the driving roller is arranged above the vacuum insulation panel.

[0010] The guiding and folding mechanism is driven to move up and down through a corresponding lifting mechanism. The lifting mechanism includes a base driven to move up and down by a corresponding first lifting cylinder. A plurality of guide rods movably penetrating through the frame are installed on the base. The guiding and folding mechanism is fixedly installed on the base.

[0011] The heat conduction mechanism includes a heat conducting part woven into a grid shape by a corresponding heat conducting material. The heat conducting part is sleeved outside the deviation correcting block and attached to the groove on the guiding belt. The periphery of the deviation correcting block is connected to the heat conducting part by electric welding. The heat conducting part is fixed on the guiding belt through an adhesive layer coated or pasted on its outer side surface and is flush with the outer surface of the guiding belt.

[0012] The wide pressing plate belt mechanism includes two wide pressing plates belts which are driven to move up and down respectively by corresponding second lifting components. The width of the wide pressing plate belt can cover the long side leaf width of the vacuum insulation panel. The first lifting component and the second lifting component have the same structure, and both include a connecting plate horizontally and fixedly installed at the end of the piston rod of the second lifting cylinder. A plurality of connecting rods fixedly connected to the pressing plate belt or the wide pressing plate belt are movably and spacedly installed on the connecting plate, and corresponding buffer springs are sleeved outside the connecting rods. The end parts of the buffer springs are respectively connected to the connecting plate and the pressing plate belt or the wide pressing plate belt.

[0013] The conveying mechanism includes two conveyor belts arranged side by side on the left and right and respectively driven by corresponding synchronous motors. A row of roller assemblies that penetrate the front and rear ends of the conveyor belts are rotatably installed side by side between the two conveyor belts. The upper end surface of the roller assembly is flush with the upper surface of the conveyor belt.

[0014] The two conveyor belts of the conveying mechanism are installed on corresponding support plates. Rotating wheels are rotatably installed at the front and rear ends of the support plates. The support plates are driven to move synchronously towards or away from each other by a corresponding displacement mechanism for adjusting the distance between the two conveyor belts. The displacement mechanism includes a wheel-rack assembly installed on the frame and connected by meshing. The rack of the wheel-rack assembly is fixedly installed on the frame, and a motor with a gear fixedly installed at the output shaft end and meshing with the rack is installed on the support plate.

[0015] A corresponding edge lifting mechanism is further provided at the front end of the side pressing mechanism. The edge lifting mechanism includes a set of guide plates respectively installed on both sides of the conveying mechanism. The guide plates are triangular structures inclined upward from the feeding end to the discharging end, and the top ends of the guide plates are vertically folded outward. An upward turning brush roller for assisting in lifting the edge and a side pressing roller group for assisting in compacting the side of the long side leaf are arranged at the rear side of the guide plates. The distance between the two upward turning brush rollers is smaller than the distance between the two guide plates.

[0016] Advantages of the present invention: 1) Without pausing the product, through the cooperation of the guiding and folding mechanism and the transmission mechanism, the long-edge leaves are smoothly guided during the movement of the product, and the hemming action of the long-edge leaves can be smoothly completed. Through the guiding and driving of the cooperation between the driving roller and the driven roller, the front end of the guiding belt is set to be upright and the rear end is set to be horizontal for torsion, so that the long-edge leaves passing through the guiding belt are gradually bent from the upright state to the horizontal state along with the twisted guiding belt, realizing the folding and hemming action; and the guiding belt is driven by the corresponding driving motor, and its linear speed is controlled to be faster than the linear speed of the transmission mechanism to effectively avoid bad conditions on the appearance of the product, ensure the hemming effect, and improve the product quality. However, due to the 90° torsion and transmission of the guiding belt, the connection between the guiding belt and the roller is prone to deviation during long-term operation. Therefore, the present invention further adds a deviation correction mechanism. By setting corresponding embedding grooves on the circumferential surfaces of the driving roller and the driven roller, and setting arc-shaped deviation correction blocks on the inner side surface of the guiding belt, on the basis of ensuring the smooth transmission of the guiding belt, the deviation correction blocks are engaged with the embedding grooves one by one in sequence, so that the guiding belt can achieve self-correction through the deviation correction mechanism during the transmission process, effectively avoiding deviation, without subsequent shutdown for deviation correction, and thus improving production efficiency.

[0017] 2) The hemming flatness of the long-edge leaves affects the subsequent corner pinching quality. Therefore, the present invention further adds a heat conduction mechanism. A heat conducting member is connected to the periphery of the deviation correction block by electric welding. When the deviation correction mechanism is transmitted along with the guiding belt, certain heat is generated due to friction. The heat is evenly distributed to the guiding belt through the heat conducting member woven into a grid shape by heat conducting materials, so as to perform a certain heat ironing and shaping on the folded long-edge leaves through the guiding belt. After the long-edge leaves are heat ironed and shaped, it helps to improve the flatness of their press-fitting connection with the vacuum insulation board, and thus promotes the improvement of the subsequent corner pinching quality; and the grid-shaped heat conducting member is attached to the groove of the guiding belt, and an adhesive is provided on the outer side surface of the heat conducting member by coating or pasting to fix the heat conducting member, so as to ensure the heat conduction effect and the dispersion effect through direct contact.

[0018] 3) Traditional folding equipment is transported by a transmission mechanism and needs to complete the processes of centering, lifting, spraying glue and side leaf bonding before folding. The process is relatively lengthy, and there is a certain distance and time between gluing and folding. During this period, dust in the air is easy to stick to the glue and affect its bonding effect. More importantly, the glue has a certain timeliness. The longer the residence time, the worse the bonding effect, and the adhesion is affected. Therefore, the present invention adjusts the position of the gluing mechanism, adjusts it to before the folding mechanism, that is, the guide folding mechanism, and immediately performs folding and bonding after applying the glue, so as to achieve the folding and bonding of the long-side leaves at the fastest speed and ensure the bonding effect. However, due to the adjustment of the position, the long side leaves may interfere with the inward deviation when they are upright and fitted, thereby inhibiting the smooth gluing. Therefore, the present invention further arranges a matching pressing plate mechanism and a guide adjustment mechanism before the gluing mechanism. The downward-moving pressing plate belt will drive the inward-inclined iron parts to guide the upright long side leaves, effectively preventing the long side leaves from tilting inward, thereby making the long side leaves of the vacuum insulation board after being transmitted out of the guide adjustment mechanism in a non-inclined state, and the gluing mechanism installed on the rear side of the guide adjustment mechanism timely applies glue, thereby ensuring the practical effect of the present invention; the iron plate is pressed to its outer surface as the pressing plate mechanism moves downward The surface is flush with the outer surface of the pressure plate belt and is fixed by a small magnet to ensure the transmission of the pressure plate belt; after the pressure plate belt is transmitted to the position of the large magnet, the iron part is tilted downward under the cooperation of the magnetic attraction of the large magnet and the elastic action of the small stiffness spring, and the iron part is out of the magnetic attraction range of the small magnet, thereby ensuring that the iron part is tilted to ensure the subsequent adjustment of the long side leaves; secondly, the pressure plate belt presses the vacuum insulation panel, and a compression spring is provided between the belt and the cylinder, which can be elastically compatible with vacuum insulation panels of different thicknesses, and can also effectively prevent the short leaves at the front from curling up.

[0019] 4) The present invention sets a corresponding side pressure mechanism before folding. The side pressure mechanism not only drives the side pressure belt to move synchronously toward or away from each other through the two-dimensional motion mechanism to correct the centering of the vacuum insulation panel and to fit and reinforce the side surfaces of the long side leaves, thereby assisting in ensuring the subsequent folding action; and a compensation component composed of a compression spring and a connecting plate is set between the moving seat of the two-dimensional motion mechanism and the driving cylinder, which can effectively compensate for the width deviation of the vacuum insulation panel, thereby ensuring that the vacuum insulation panel accurately enters the guide folding mechanism, preventing the vacuum insulation panel from deviating and causing jamming and inhibiting the smooth progress of the processing, thereby promoting the quality of folding, thereby improving the applicability of the folding equipment.

[0020] 5) The guide folding mechanism of the present invention adjusts the height up and down through the corresponding lifting mechanism to adapt to the folding requirements of vacuum insulation panels of different thicknesses, thereby improving the applicability of the equipment. The entire equipment is installed on a support plate, and then driven to move left and right by a displacement mechanism to adapt to vacuum insulation panels of different widths, thereby further improving the applicability of the equipment.

[0021] 6) A corresponding edge-lifting mechanism is further provided in front of the side pressing mechanism of the present invention. The long-edge leaves that are turned down on both sides of the long edge of the vacuum insulation panel are lifted by a guide plate in the shape of an upwardly inclined triangle structure, and are assisted in edge-lifting by a turning-up brush roller, and then are compacted by a side pressing roller set to ensure full edge-lifting, thereby promoting the hemming action.

Detailed implementation mode

[0031] 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 conjunction with the attached drawings: Embodiment 1 Refer to Figures 1-5 , a high adaptability vacuum insulation board hemming device, comprising: Frame 1, Transmission mechanism 2, installed on the frame 1 and transmitting the vacuum insulation board by belt transmission; Side pressing mechanism 3, installed on both sides of the transmission mechanism 2 and moving left and right for correcting and centering the vacuum insulation board and attaching and standing the long side leaves on its side; Guiding and folding mechanism 4, including two guiding belts 401 arranged on both sides of the transmission mechanism 2, and a driving roller 402 and a driven roller 403 driven by corresponding driving motors 404 are respectively connected in front of and behind the guiding belt 401; through the cooperation and guidance of the driving roller 402 and the driven roller 403, the front end of the guiding belt 401 is set to be upright and the rear end is set to be horizontal for torsion; The deviation rectifying mechanism 5 includes deviation rectifying blocks 501 uniformly and fixedly installed on the inner side of the guiding belt 401 by bonding, and embedding grooves 502 respectively and uniformly embedded in the circumferential surfaces of the driving roller 402 and the driven roller 403. The shapes of the deviation rectifying blocks 501 and the embedding grooves 502 are arc-shaped surfaces that match each other. When the driving roller 402 and the driven roller 403 cooperate to drive the guiding belt 401 to transmit, the guiding belt 401 is self-corrected through the one-to-one correspondence and sequential meshing connection between the deviation rectifying blocks 501 and the embedding grooves 502. The heat conduction mechanism 6 is used to uniformly transfer the heat generated by friction when the deviation rectifying mechanism 5 is transmitted along with the guiding belt 401 to the guiding belt 401, so as to conduct heat through the guiding belt 401 to thermally iron and shape the folded long-edge leaves. The wide pressing plate belt mechanism 7 is installed above the transmission mechanism 2 and cooperates with the transmission mechanism 2 to press the vacuum insulation panel so that the folded long-edge leaves are adhesively connected to the vacuum insulation panel.

[0032] The center lines of the driving roller 402 and the driven roller 403 are in a vertical state, that is, the driving roller 402 is vertically arranged and the driven roller 403 is horizontally arranged. The distance between the two driven rollers 403 is less than the distance between the two driving rollers 402, and the inner end of the driving roller 402 is arranged above the vacuum insulation panel.

[0033] Without pausing the product, through the cooperation of the guiding and folding mechanism 4 and the transmission mechanism 2, the long-edge leaves are smoothly guided during the movement of the product, and the folding action of the long-edge leaves can be smoothly completed. Through the cooperation of the driving roller 402 and the driven roller 403 for guiding and transmission, the front end of the guiding belt 401 is set to be upright and the rear end is set to be horizontal for torsion, so that the long-edge leaves passing through the guiding belt 401 are gradually bent from the upright state to the horizontal state along with the twisted guiding belt 401, realizing the folding and hemming action; and the guiding belt 401 is driven by the corresponding driving motor 404, and its linear speed is controlled to be faster than the linear speed of the transmission mechanism 2 to effectively avoid the appearance of defective products, ensure the hemming effect, and improve the product quality. However, due to the 90° torsion and transmission of the guiding belt 401, the connection between the guiding belt 401 and the roller is likely to shift during long-term operation. Therefore, the present invention further adds a deviation correction mechanism 5. By setting corresponding embedding grooves 502 on the circumferential surfaces of the driving roller 402 and the driven roller 403, and setting arc-shaped deviation correction blocks 501 on the inner side surface of the guiding belt 401, on the basis of ensuring the smooth transmission of the guiding belt 401, the deviation correction blocks 501 and the embedding grooves 502 are engaged with each other in sequence one by one, so that the guiding belt 401 can achieve self-correction through the deviation correction mechanism 5 during the transmission process, effectively avoiding deviation, without subsequent shutdown for deviation correction, and thus improving the production efficiency.

[0034] The side pressing mechanism 3 includes two side pressing belts 302 respectively driven by corresponding driving motors 301. The side pressing belts 302 are driven by a two-dimensional motion mechanism 8 fixedly installed on the frame 1. The two-dimensional motion mechanism 8 includes a fixed guide rail 801 horizontally arranged on the frame 1. A movable seat 804 driven by a corresponding driving cylinder 802 is movably installed on the fixed guide rail 801. The side pressing belt 302 is installed on the movable seat 804; a compensation assembly 803 for compensating the width deviation of the vacuum insulation panel is arranged between the movable seat 804 and the driving cylinder 802. The compensation assembly 803 includes a group of connecting plates 8031 respectively fixed to the end parts of the movable seat 804 and the piston rod of the driving cylinder 802, and a corresponding compression spring 8032 is connected and installed between the two connecting plates 8031.

[0035] Before hemming, a corresponding side pressing mechanism 3 is provided in the present invention. The side pressing mechanism 3 not only drives the side pressing belt 302 to move synchronously towards or away from each other through a two-dimensional motion mechanism 8 to correct the alignment of the vacuum insulation panel and perform upright reinforcement on the side surface of its long side leaves, thereby assisting in ensuring the subsequent hemming operation; moreover, a compensation assembly 803 composed of a compression spring 8032 and an adapter plate 8031 is provided between the moving seat 804 and the driving cylinder 802 of the two-dimensional motion mechanism 8, which can effectively compensate for the width deviation of the vacuum insulation panel, and then ensure that the vacuum insulation panel accurately enters the guiding and folding mechanism 4, preventing the vacuum insulation panel from deviating and causing jamming to inhibit the smooth progress of processing, and further promoting the quality of hemming, thereby improving the applicability of the hemming equipment.

[0036] The guiding and folding mechanism 4 is driven to move up and down through a corresponding lifting mechanism 12. The lifting mechanism 12 includes a base 1202 driven to move up and down by a corresponding first lifting cylinder 1201. A plurality of guide rods 1203 movably passing through the frame 1 are installed on the base 1202, and the guiding and folding mechanism 4 is fixedly installed on the base 1202.

[0037] The heat conduction mechanism 6 includes a heat conducting member 601 woven into a grid shape by a corresponding heat conducting material such as copper wire. The heat conducting member 601 is sleeved outside the deviation correcting block 501 and attached in a groove on the guiding belt 401. The periphery of the deviation correcting block 501 is connected to the heat conducting member 601 by electric welding. The heat conducting member 601 is fixed on the guiding belt 401 through an adhesive layer 602 coated or pasted on its outer side surface and is flush with the outer surface of the guiding belt 401.

[0038] The hemming flatness of the long-edge leaves affects the subsequent corner-pinching quality. Therefore, the present invention further adds a heat-conducting mechanism 6. A heat-conducting member 601 is connected to the periphery of the deviation-correcting block 501 by electric welding. When the deviation-correcting mechanism 5 is conveyed along with the guiding belt 401, a certain amount of heat is generated due to friction. The heat is evenly distributed to the guiding belt 401 through the grid-shaped heat-conducting member 601 made of heat-conducting material, so as to thermally iron and shape the folded long-edge leaves through the guiding belt 401. After the long-edge leaves are thermally ironed and shaped, it helps to improve the flatness of their pressing connection with the vacuum insulation panel, thereby promoting the improvement of the subsequent corner-pinching quality. And the grid-shaped heat-conducting member 601 is attached to the groove of the guiding belt 401, and an adhesive is provided on the outer side surface of the heat-conducting member 601 by coating or pasting to fix the heat-conducting member 601, so as to ensure the heat-conducting effect and the dispersion effect through direct contact. The belt surface of the guiding belt 401 can also be made of a material with heat-conducting effect, and its inner side surface is made of non-heat-conducting material or the tube part of the roller is made of non-heat-conducting material, effectively avoiding the external dissipation of heat through the roller and ensuring that the heat is more comprehensively conducted to the long-edge leaves through the guiding belt 401, so as to ensure the heat-conducting effect and avoid excessive heat transfer to the roller.

[0039] The wide pressing belt mechanism 7 includes two wide pressing belts 702 that are respectively driven to move up and down by corresponding second lifting components 701. The width of the wide pressing belt 702 can cover the width of the long-edge leaves of the vacuum insulation panel. The first lifting component 1001 and the second lifting component 701 have the same structure, and both include a connecting plate 7012 horizontally and fixedly installed at the end of the piston rod of the second lifting cylinder 7011. A plurality of connecting rods 7013 that are fixedly connected to the pressing belt 1002 or the wide pressing belt 702 are movably and spacedly installed on the connecting plate 7012, and corresponding buffer springs 7014 are sleeved on the outer sides of the connecting rods 7013. The end parts of the buffer springs 7014 are respectively connected to the connecting plate 7012 and the pressing belt 1002 or the wide pressing belt 702.

[0040] The transmission mechanism 2 includes two transmission belts 202 that are arranged side by side on the left and right and are respectively driven to rotate by corresponding synchronous motors 201. A row of roller assemblies 203 that penetrate through the front and rear ends of the two transmission belts 202 are rotatably installed side by side between the two transmission belts 202, and the upper end surfaces of the roller assemblies 203 are flush with the upper surfaces of the transmission belts 202.

[0041] The two conveyor belts 202 of the conveyor mechanism 2 are installed on the corresponding support plates 13. Rotating wheels 14 are rotatably installed at both the front and rear ends of the support plate 13. The support plate 13 is driven to move synchronously towards or away from each other by a corresponding displacement mechanism 15 for adjusting the distance between the two conveyor belts 202. The displacement mechanism 15 includes a rack and pinion assembly 1501 installed on the frame 1 and connected by meshing. The rack of the rack and pinion assembly 1501 is fixedly installed on the frame 1, and a motor 1502 with a gear fixedly installed at the output shaft end and meshing with the rack is installed on the support plate 13.

[0042] The guiding and folding mechanism 4 of the present invention is adjusted in height up and down by a corresponding lifting mechanism 12 to meet the hemming requirements of vacuum insulation panels with different thicknesses, improving the applicability of the equipment. And the whole equipment is installed on the support plate 13, and then driven to move left and right by the displacement mechanism 15 to adapt to vacuum insulation panels with different widths, further improving the applicability of the equipment.

[0043] Embodiment 2 Reference Figures 6-8 , the difference between this embodiment and Embodiment 1 is that: the hemming device further includes: A gluing mechanism 9, which is used to apply glue to the relative two sides of the upper surface of the vacuum insulation panel by spraying or coating, and is installed between the side pressing mechanism 3 and the guiding and folding mechanism 4; A pressing plate mechanism 10, installed at the front end of the gluing mechanism 9 and inside the side pressing mechanism 3, includes two pressing plate belts 1002 respectively driven to move up and down by corresponding first lifting components 1001. The pressing plate belts 1002 are driven to rotate by a corresponding power motor 1003; and the radius of the roller for installing and driving the pressing plate belt 1002 is greater than the width of the long side leaf of the vacuum insulation panel. The guiding and adjusting mechanism 11 includes a plurality of iron parts 1102 that are evenly distributed at intervals in the front-rear direction and are installed in a limited and inclined hinged manner on the outer side wall of the pressing plate belt 1002 through corresponding small-stiffness springs 1101, and small magnets 1103 that are fixedly installed on the pressing plate belt 1002 corresponding to the iron parts 1102 one by one. The iron parts 1102 are arranged on the side of the pressing plate belt 1002 facing the side pressing mechanism 3. The outer end of the iron part 1102 extends outward to be flush with the outside of the roller that drives the pressing plate belt 1002, and is located inside the base on which the pressing plate belt 1002 is installed. After the pressing plate mechanism 10 moves down and presses on the upper surface of the vacuum insulation panel, the iron part 1102 is pressed to be flush with the outer surface of the pressing plate belt 1002, and the iron part 1102 is adsorbed and fixed by the small magnet 1103, and the small-stiffness spring 1101 is compressed. The guiding and adjusting mechanism 11 further includes a large magnet 1104 that is installed at intervals at the front end of the pressing plate belt 1002. The magnetic force of the large magnet 1104 is greater than the magnetic force of the small magnet 1103. When the pressing plate belt 1002 drives the iron part 1102 to the relative position of the large magnet 1104, the iron part 1102 is inclined downward under the cooperation of the magnetic attraction of the large magnet 1104 and the elastic action of the small-stiffness spring 1101, and the iron part 1102 is out of the magnetic attraction range of the small magnet 1103.

[0044] The traditional hemming device is conveyed through the conveying mechanism 2, and during the conveyance, it needs to complete the processes of centering, edge lifting, glue spraying, and side leaf fitting before the hemming process. The process is relatively long, and there is a certain distance and time between glue application and hemming. During this period, dust in the air is likely to adhere to the glue, affecting its bonding effect. More importantly, the glue has a certain shelf life, and the longer the residence time, the worse the bonding effect, and the adhesiveness is affected. Therefore, in the present invention, the position of the gluing mechanism 9 is adjusted to be before the hemming mechanism, i.e., the guiding and folding mechanism 4, so that the hemming and bonding are carried out immediately after the glue is applied, and the folding and bonding of the long side leaves are achieved at the fastest speed to ensure the bonding effect. However, due to the position adjustment, the long side leaves may interfere due to inward deviation during the vertical fitting, which inhibits the smooth progress of glue application. Therefore, in the present invention, a matching pressing plate mechanism 10 and a guiding and adjusting mechanism 11 are further provided before the gluing mechanism 9. The downward-moving pressing plate belt 1002 drives the inwardly inclined iron part 1102 to guide the vertical long side leaves, effectively preventing the long side leaves from inclining inward. As a result, the long side leaves of the vacuum insulation panel after being transmitted through the guiding and adjusting mechanism 11 are in a non-inclined state, and are timely coated with glue by the gluing mechanism 9 installed behind the guiding and adjusting mechanism 11 to ensure the practical effect of the present invention; after the iron plate moves downward with the pressing plate mechanism 10, it is pressed to be flush with the outer surface of the pressing plate belt 1002 and is adsorbed and fixed by the small magnet 1103 to ensure the transmission of the pressing plate belt 1002; when the pressing plate belt 1002 is transmitted to the position of the large magnet 1104, the iron part 1102 is inclined downward under the cooperation of the magnetic attraction of the large magnet 1104 and the elastic action of the small stiffness spring 1101, and the iron part 1102 is out of the magnetic attraction range of the small magnet 1103, so as to ensure that the iron part 1102 is in an inclined state to ensure the subsequent adjustment effect on the long side leaves; furthermore, the pressing plate belt 1002 presses the vacuum insulation panel, and a compression spring 8032 is provided between the belt and the cylinder, which can be elastically compatible with vacuum insulation panels of different thicknesses, and can also well avoid the phenomenon of curling for the front short leaves with the situation of warping.

[0045] A corresponding edge lifting mechanism 16 is further provided at the front end of the side pressing mechanism 3. The edge lifting mechanism 16 includes a set of guiding plates 1601 respectively installed on both sides of the conveying mechanism 2. The guiding plates 1601 are triangular structures inclined upward from the feeding end to the discharging end, and the top ends of the guiding plates 1601 are vertically folded outward; an upward-turning brush roller 1602 for assisting in edge lifting and a side pressing roller group 1603 for assisting in compacting the side of the long side leaves are provided at the rear side of the guiding plates 1601, and the distance between the two upward-turning brush rollers 1602 is smaller than the distance between the two guiding plates 1601.

[0046] Before the side pressing mechanism 3, the present invention also provides a corresponding edge lifting mechanism 16. The edge lifting mechanism 16 uses a guide plate 1601 with an upwardly inclined triangular structure to lift the long edge leaves that are turned down on both sides of the long edge of the vacuum insulation panel, and is assisted by an upwardly turning brush roller 1602 for edge lifting, and then is compacted by a side pressing roller group 1603 to ensure comprehensive edge lifting, thereby promoting the edge folding action.

[0047] It should be noted that the implementation principle and the technical effects produced by this embodiment are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0048] 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.
