Description

Technical Field

[0001] The present invention relates to the technical field of vacuum insulation panel production equipment, in particular to a vacuum insulation panel folding device with high adaptability. Background Art

[0002] Vacuum insulation panels are a type of vacuum insulation material, composed of a filler core and a vacuum protective surface layer. They effectively prevent heat transfer caused by air convection, significantly reducing thermal conductivity. They are primarily used in cold chain equipment such as refrigerators, freezers, refrigerated trucks, and cold storage, as well as exterior wall insulation systems for residential, commercial, office, and public facilities. They are an excellent material for reducing power consumption. With increasing global demand for environmental protection and energy conservation, their application is becoming increasingly widespread.

[0003] After the filler core material is laminated with the vacuum protective surface layer, redundant edges are formed around the edges. These edges need to be folded and flattened to the top of the vacuum insulation panel to ensure the panel's usability. Traditionally, there are two main methods for folding vacuum insulation panels: manual folding, which has low production efficiency, high labor intensity, high product manufacturing costs, and inconsistent quality. The other method is to use automated equipment to reduce labor costs and improve efficiency and quality. However, existing automated equipment has complex structures and operating procedures. The most time-consuming process of folding the long edges of vacuum insulation panels is folding the long edges. Existing folding mechanisms all mimic the manual folding process. A drive mechanism moves up and down and left and right, driving multiple folding panels arranged side by side to fold the redundant edges of the vacuum insulation panel upward and inward. The folding panels then rotate in the opposite direction through their structure. As the folding panels move, their lower ends scrape across the redundant edges, folding and pressing the redundant edges together. Moreover, at present, most folding equipment requires the product to stop before folding the long sides of the vacuum insulation panel. Not only is the structure complex, but the operation process is also cumbersome and the efficiency stagnates.

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

[0027] Advantages of the present invention:

[0028] 1) The present invention can smoothly guide the long-side leaves during the movement of the product through the cooperation of the guide folding mechanism and the transmission mechanism without stopping the product, so as to smoothly complete the folding action of the long-side leaves. Through the coordinated guidance and transmission of the active roller and the driven roller, the front end of the guide belt is set to an upright shape and the rear end is set to a horizontal shape for twisting, so that the long-side leaves passing through the guide belt are gradually bent from an upright shape to a horizontal shape as the twisted guide belt is twisted, thereby realizing the folding and folding action; and the guide belt is driven by the corresponding transmission motor to control its linear speed to be faster than the linear speed of the transmission mechanism, so as to effectively avoid poor product appearance, ensure the folding effect, and improve product quality. However, since the guide belt realizes 90° twisting and transmission, the connection between the guide belt and the roller is likely to be offset during long-term operation. Therefore, the present invention further adds a correction mechanism, and arranges corresponding embedded grooves on the circumferential surfaces of the active roller and the driven roller, and arranges arc-shaped correction blocks on the inner side surface of the guide belt. On the basis of ensuring smooth transmission of the guide belt, the correction blocks and the embedded grooves are meshed and connected in sequence one by one, so that the guide belt can achieve self-correction through the correction mechanism during the transmission process, effectively avoiding deviation, and eliminating the need for subsequent shutdown correction, thereby improving production efficiency.

[0029] 2) The flatness of the folded edge of the long-side leaf affects the subsequent quality of the angle pinching. Therefore, the present invention further adds a heat-conducting mechanism. A heat-conducting member is connected to the periphery of the correction block by electric welding. When the correction mechanism is transmitted along the guide belt, a certain amount of heat is generated due to friction. The heat is evenly distributed to the guide belt through a grid-shaped heat-conducting member made of heat-conducting material, so that the folded long-side leaf is subjected to a certain degree of hot-stamping and shaping through the guide belt. After the long-side leaf is hot-stamped and shaped, it helps to achieve the flatness of the press connection with the vacuum insulation panel, thereby promoting the improvement of the subsequent angle pinching quality; and the grid-shaped heat-conducting member is attached to the groove of the guide belt, and the outer side of the heat-conducting member is provided with adhesive by coating or pasting to fix the heat-conducting member, so as to ensure the heat conduction effect and dispersion effect through direct contact.

[0030] 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 the folding process can be carried out. The process is relatively lengthy, and there is a certain distance and time between gluing and folding. During this period, dust in the air easily sticks to the glue and affects its bonding effect. More importantly, the glue has a certain timeliness. The longer the residence time, the worse the bonding effect and the adhesion are affected. Therefore, the present invention adjusts the position of the gluing mechanism to before the folding mechanism, that is, the guide folding mechanism. After applying the glue, the folding and bonding are immediately carried out to achieve the folding and bonding of the long-side leaves at the fastest speed to ensure the bonding effect. However, due to the adjustment of the position, the long-side leaves may interfere with the inward deviation when standing upright and fitting, 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 panel 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, 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 curling of the short leaves at the front end.

[0031] 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 and the driving cylinder of the two-dimensional motion mechanism, 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.

[0032] 5) The guide folding mechanism of the present invention is adjusted in height up and down by a 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, further improving the applicability of the equipment.

[0033] 6) The present invention also provides a corresponding edge lifting mechanism in front of the side pressure mechanism, which uses a guide plate with an upwardly inclined triangular structure to lift the long edge leaves on both sides of the long side of the vacuum insulation panel, and cooperates with the upward-turning brush roller to assist in lifting the edge, and then cooperates with the side pressure roller group to compact, so as to ensure comprehensive edge lifting and promote the folding action.

DETAILED DESCRIPTION

[0043] 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 and the accompanying drawings:

[0044] Example 1

[0045] refer to Figure 1-5 , a highly adaptable vacuum insulation panel folding device, comprising:

[0046] Rack 1,

[0047] Transmission mechanism 2, mounted on the frame 1 and conveying the vacuum insulation panel by belt conveyor;

[0048] The side pressure mechanism 3 is installed on both sides of the transmission mechanism 2 for correcting the centering of the vacuum insulation panel and fitting the side faces of the long leaves upright;

[0049] The guide folding mechanism 4 includes two guide belts 401 arranged on both sides of the transmission mechanism 2. The guide belts 401 are respectively connected to the front and rear of the guide belts 401 with a driving roller 402 and a driven roller 403 driven by corresponding transmission motors 404. The driving rollers 402 and the driven rollers 403 cooperate to guide the guide belts 401 so that the front end is set to an upright position and the rear end is set to a horizontal position for twisting.

[0050] The correcting mechanism 5 includes correcting blocks 501 uniformly fixedly mounted on the inner side of the guide belt 401 by bonding, and embedding grooves 502 uniformly embedded in the circumferential surfaces of the active roller 402 and the driven roller 403. The correcting blocks 501 and the embedding grooves 502 are shaped like matching arc surfaces. When the active roller 402 and the driven roller 403 cooperate to drive the guide belt 401, the correcting blocks 501 and the embedding grooves 502 are meshed and connected in sequence in a one-to-one correspondence to achieve self-correction of the guide belt 401.

[0051] The heat conducting mechanism 6 is used to evenly transfer the heat generated by friction when the deflection correcting mechanism 5 is transported along the guide belt 401 to the guide belt 401, so as to heat and shape the folded long-side leaves through the guide belt 401;

[0052] 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-side leaves are bonded and connected to the vacuum insulation panel.

[0053] The center lines of the active roller 402 and the driven roller 403 are in a vertical state, that is, the active roller 402 is arranged upright and the driven roller 403 is arranged horizontally. The distance between the two driven rollers 403 is smaller than the distance between the two active rollers 402. The inner end of the active roller 402 is arranged above the vacuum insulation panel.

[0054] The present invention can smoothly guide the long-side leaves during the movement of the product through the cooperation of the guide folding mechanism 4 and the transmission mechanism 2 without stopping the product, and can smoothly complete the folding action of the long-side leaves. Through the coordinated guidance and transmission of the active roller 402 and the driven roller 403, the front end of the guide belt 401 is set to an upright shape and the rear end is set to a horizontal shape for twisting, so that the long-side leaves passing through the guide belt 401 are gradually bent from an upright shape to a horizontal shape as the twisted guide belt 401 is twisted, thereby realizing the folding and folding action; and the guide belt 401 is driven by the corresponding transmission motor 404 to control its linear speed to be faster than the linear speed of the transmission mechanism 2, so as to effectively avoid poor product appearance, ensure the folding effect, and improve product quality. However, since the guide belt 401 realizes 90° twisting and transmission, the connection between the guide belt 401 and the roller is easily offset during long-term operation. Therefore, the present invention further adds a correction mechanism 5, and sets corresponding embedding grooves 502 on the circumferential surfaces of the active roller 402 and the driven roller 403, and sets an arc-shaped correction block 501 on the inner side surface of the guide belt 401. On the basis of ensuring the smooth transmission of the guide belt 401, the correction block 501 and the embedding groove 502 are meshed and connected in sequence one by one, so that the guide belt 401 can achieve self-correction through the correction mechanism 5 during the transmission process, effectively avoiding deviation, and eliminating the need for subsequent shutdown correction, thereby improving production efficiency.

[0055] The side pressure mechanism 3 includes two side pressure belts 302 respectively driven by corresponding drive motors 301, and the side pressure belts 302 are driven by a two-dimensional motion mechanism 8 fixedly mounted on the frame 1. The two-dimensional motion mechanism 8 includes a fixed guide rail 801 horizontally arranged on the frame 1, and a moving seat 804 driven by a corresponding driving cylinder 802 is movably mounted on the fixed guide rail 801, and the side pressure belt 302 is mounted on the moving seat 804; a compensation component 803 for compensating for the width deviation of the vacuum insulation panel is provided between the moving seat 804 and the driving cylinder 802, and the compensation component 803 includes a group of connecting plates 8031 ​​respectively fixed to the moving seat 804 and the piston rod end of the driving cylinder 802, and a corresponding compression spring 8032 is connected and installed between the two connecting plates 8031.

[0056] The present invention sets a corresponding side pressure mechanism 3 before folding. The side pressure mechanism 3 not only drives the side pressure belt 302 to move synchronously toward or away from each other through the two-dimensional motion mechanism 8 to correct the centering of the vacuum insulation panel and to fit and reinforce the side of the long side leaves, thereby assisting in ensuring the subsequent folding action; and a compensation component 803 composed of a compression spring 8032 and a connecting plate 8031 ​​is set between the moving seat 804 of the two-dimensional motion mechanism 8 and the driving cylinder 802, 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 4, preventing the vacuum insulation panel from deviating and causing jamming and inhibiting the smooth progress of processing, thereby promoting the quality of folding, thereby improving the applicability of the folding equipment.

[0057] The guide folding mechanism 4 is driven to move up and down by the corresponding lifting mechanism 12. The lifting mechanism 12 includes a base 1202 driven to move up and down by the corresponding first lifting cylinder 1201. The base 1202 is equipped with multiple guide rods 1203 that are movable and pass through the frame 1. The guide folding mechanism 4 is fixedly installed on the base 1202.

[0058] The heat-conducting mechanism 6 includes a heat-conducting member 601 woven into a grid from corresponding heat-conducting materials such as copper wire.

The periphery of the correction block 501 is connected to the heat-conducting member 601 by electric welding. The heat-conducting member 601 is fixed to the guide belt 401 by an adhesive layer 602 coated or pasted on its outer side and is flush with the outer surface of the guide belt 401.

[0059] The flatness of the folded edge of the long-side leaf affects the quality of the subsequent pinching angle, so the present invention further adds a heat-conducting mechanism 6. A heat-conducting member 601 is connected to the periphery of the correction block 501 by electric welding. When the correction mechanism 5 is transmitted along the guide belt 401, a certain amount of heat is generated due to friction. The heat is evenly distributed to the guide belt 401 through the grid-shaped heat-conducting member 601 made of heat-conducting material, so that the folded long-side leaf is subjected to a certain amount of hot-stamping and shaping through the guide belt 401. After the long-side leaf is hot-stamped and shaped, it helps to achieve the flatness of the press connection with the vacuum insulation panel, thereby promoting the improvement of the subsequent pinching. Angular quality; and the grid-shaped heat conductor 601 is attached to the groove of the guide belt 401, and the outer side of the heat conductor 601 is provided with glue by coating or pasting to fix the heat conductor 601, so as to ensure the heat conduction effect and the dispersion effect through direct contact; the belt surface of the guide belt 401 can also be a material with a heat conduction effect, and its inner side is a non-heat conduction material or the tube part of the roller is a non-heat conduction material, which effectively avoids the heat from dissipating through the roller, and ensures that the heat is more comprehensively conducted to the long-side leaves through the guide belt 401, so as to ensure the heat conduction effect and avoid excessive heat transfer to the roller.

[0060] The wide pressure plate belt mechanism 7 includes two wide pressure plate belts 702 that are driven to move up and down by corresponding second lifting components 701 respectively. The width of the wide pressure plate belt 702 can cover the width of the long side 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 that is laterally fixedly installed on the end of the piston rod of the second lifting cylinder 7011. A plurality of connecting rods 7013 fixedly connected to the pressure plate belt 1002 or the wide pressure plate belt 702 are movably installed on the connecting plate 7012 at intervals, and a corresponding buffer spring 7014 is provided on the outer side of the connecting rod 7013. One end of the buffer spring 7014 is connected to the connecting plate 7012, and the other end thereof is connected to the pressure plate belt 1002 or the wide pressure plate belt 702.

[0061] The transmission mechanism 2 includes two transmission belts 202 arranged side by side on the left and right and driven by corresponding synchronous motors 201 respectively. A row of roller assemblies 203 arranged side by side with the transmission belts 202 are rotatably installed between the two transmission belts 202, and the upper end surface of the roller assembly 203 is flush with the upper surface of the transmission belt 202.

[0062] The two transmission belts 202 of the transmission mechanism 2 are installed on the corresponding support plates 13, and the front and rear ends of the support plates 13 are rotatably installed with corresponding rotating wheels 14. The support plates 13 are driven by the corresponding displacement mechanisms 15 to move synchronously toward or away from each other, so as to adjust the spacing between the two transmission belts 202; the displacement mechanism 15 includes a wheel spoke assembly 1501 installed on the frame 1 and connected by meshing, and the rack of the wheel spoke assembly 1501 is fixedly installed on the frame 1, and the corresponding motor 1502 is installed on the support plate 13, and the output shaft end of the motor 1502 is fixedly installed with a gear meshing with the rack.

[0063] The guide folding mechanism 4 of the present invention is adjusted in height up and down by a corresponding lifting mechanism 12 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 13 and then driven to move left and right by a displacement mechanism 15 to adapt to vacuum insulation panels of different widths, thereby further improving the applicability of the equipment.

[0064] Example 2

[0065] refer to Figure 6-8 The difference between this embodiment and the first embodiment is that the folding device further includes:

The pressing plate belts 1002 are driven by corresponding power motors 1003. The radius of the roller that mounts and drives the pressing plate belts 1002 is greater than the width of the long side leaf of the vacuum insulation panel.

[0068] The guide adjustment mechanism 11 comprises a plurality of iron parts 1102 which are evenly spaced front to back and are hingedly mounted on the outer wall of the pressure plate belt 1002 by means of corresponding small stiffness springs 1101, and small magnets 1103 which are fixedly mounted on the pressure plate belt 1002 in a one-to-one correspondence with the iron parts 1102. The iron parts 1102 are arranged on the side of the pressure plate belt 1002 facing the side pressure mechanism 3. The outer end of the iron part 1102 extends outward to be flush with the outer side of the roller driving the pressure plate belt 1002 and is located on the inner side of the base on which the pressure plate belt 1002 is installed. After the pressure plate mechanism 10 is moved down and pressed above the vacuum insulation panel, the iron part 1102 is pressed to its outer surface. The surface is flush with the outer surface of the pressure 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 guide adjustment mechanism 11 also includes a large magnet 1104 installed at intervals at the front end of the pressure plate belt 1002, and the magnetic force of the large magnet 1104 is greater than the magnetic force of the small magnet 1103. When the pressure plate belt 1002 drives the iron part 1102 to the position corresponding to the large magnet 1104, the iron part 1102 is tilted 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.

[0069] The traditional folding equipment is transported by the transmission mechanism 2 and needs to complete the processes of centering, lifting, spraying glue and side leaf bonding before the folding process is carried out. The process is relatively lengthy, and there is a certain distance and time between gluing and folding. During this period, dust in the air easily sticks to the glue and affects its bonding effect. More importantly, the glue has a certain timeliness. The longer the residence time, the worse the bonding effect and the cohesiveness are affected. Therefore, the present invention adjusts the position of the gluing mechanism 9, adjusts it to before the folding mechanism, that is, the guide folding mechanism 4, and immediately performs folding and bonding after the glue is applied, 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 standing upright and fitting, thereby inhibiting the smooth gluing. Therefore, the present invention further arranges a matching pressing plate mechanism 10 and a guide adjustment mechanism 11 before the gluing mechanism 9. The downward-moving pressing plate belt 1002 will drive the inward-inclined iron parts 1102 to guide the upright long-side leaves, effectively preventing the long-side leaves from tilting inward, and thus making the long-side leaves of the vacuum insulation panel after being transmitted out of the guide adjustment mechanism 11 in a non-inclined state, and the gluing mechanism 9 installed on the rear side of the guide adjustment mechanism 11 will apply glue in time, ensuring the practical effect of the present invention; as the pressing plate mechanism 10 moves downward, the iron plate is pressed until its outer surface is flush with the outer surface of the pressing plate belt 1002. The iron part 1102 is flat and fixed by the small magnet 1103 to ensure the transmission of the pressure plate belt 1002; after the pressure plate belt 1002 is transmitted to the position of the large magnet 1104, the iron part 1102 is tilted 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, thereby ensuring that the iron part 1102 is tilted to ensure the subsequent adjustment of the long-side leaves; furthermore, the pressure 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 effectively prevent the short leaves at the front from curling up.

[0070] The front end of the side pressure mechanism 3 is also provided with a corresponding side lifting mechanism 16, and the side lifting mechanism 16 includes a group of guide plates 1601 respectively installed on both sides of the transmission mechanism 2, and the guide plate 1601 is a triangular structure inclined upward from the feed end to the discharge end, and the top of the guide plate 1601 is folded vertically outward; the rear side of the guide plate 1601 is provided with an upper brush roller 1602 for assisting in lifting the side and a side pressure roller group 1603 for assisting in compacting the side edges of the long leaves, and the spacing between the two upper brush rollers 1602 is smaller than the spacing between the two guide plates 1601.

[0071] The present invention also provides a corresponding edge lifting mechanism 16 in front of the side pressure mechanism 3, which lifts the long side leaves on both sides of the long side of the vacuum insulation panel through the guide plate 1601 with an upward inclined triangular structure, and cooperates with the upward brush roller 1602 to assist in lifting the edge, and then cooperates with the side pressure roller group 1603 to compact, so as to ensure comprehensive lifting of the edge, thereby promoting the folding action.

[0072] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
