Description

Technical Field

[0001] This utility model relates to the technical field of vacuum insulation panel production equipment, specifically to a redundant pinching device for automatic vacuum insulation panel production equipment. Background Technology

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

[0003] After the core material is laminated with the vacuum protective surface layer, redundant edges are generated around its perimeter. These redundant edges need to be bent and flattened to be shaped and positioned on top of the vacuum insulation panel to ensure its usability. Traditionally, vacuum insulation panel edge folding is done in two main ways: manual folding, which is inefficient, labor-intensive, costly, and produces inconsistent quality; and automated equipment to reduce labor costs and improve efficiency and quality. However, existing automated equipment is complex in structure, and the operation procedures at each station are also complicated. For example, a continuous edge pressing machine is needed to bend and flatten the redundant long edges before applying tape for fixation. However, if the continuous edge pressing machine jams in the middle, it must be stopped for repair, affecting production progress. Furthermore, existing folding mechanisms mimic the manual folding process. A drive mechanism moves the panel up and down and left and right, moving numerous folding plates arranged side by side to fold the redundant edges of the vacuum insulation panel upwards and inwards. The structure of the folding plates then causes them to rotate in the opposite direction. As the folding plates move, their lower ends scrape over the redundant edges, thus folding and pressing them together. However, the folding plate not only has a complex connection structure, but if its rotation gets stuck, it will cause the entire folding equipment to jam and stop. In addition, its operation process is cumbersome and its efficiency is stagnant. Furthermore, the corner pinching mechanism pinches the corner by folding the height connection between the long and short folding edges inward. However, it has high requirements for the flatness of the height connection. Otherwise, the corner pinching position will be bent and gathered, which will affect the quality of the subsequent short side folding.

[0004] Therefore, the research objective of this utility model is to design an automated production equipment for vacuum insulation panels that is simple in structure, easy to operate, and readily implementable. Utility Model Content

[0005] To address the technical problems existing in the prior art, this utility model provides a redundant pinching device for an automatic production equipment of vacuum insulation panels, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A redundant corner pinching device for an automated vacuum insulation panel production line includes:

[0008] A frame, on which a front-to-back transmission mechanism is provided, the transmission mechanism comprising two synchronously operating conveyor belts spaced apart to the left and right;

[0009] The front pinching mechanism is installed at the discharge end of the front conveying mechanism and is used to push the redundant long side folded part and the redundant short side connection point of the front side of the vacuum insulation board inward.

[0010] The rear pinching mechanism, installed at the discharge end of the rear conveyor mechanism, is used to push the connection between the redundant long side folded portion and the redundant short side of the rear side of the vacuum insulation panel inward to form a pinching corner. It has the same structure as the front pinching mechanism, both including two sets of symmetrical and synchronously driven pinching components arranged on the outside of the two conveyor belts. The pinching component includes a positioning component and a flattening component that are staggered vertically and move relatively. After the positioning component is pressed and moved into place on the redundant short side, the flattening component moves inward along the upper surface of the positioning component and pushes the redundant long side inward along the positioning component to form a pinching corner.

[0011] The outer end face of the positioning member is inclined. After the positioning member moves into place along the redundant short side to the connection point of the redundant long side, the pushing member pushes the redundant long side to move inward along the inclined surface of the positioning member to form an inwardly inclined side.

[0012] The pinching component also includes a pressing component that can be moved up and down and is disposed on the outside of the pushing component; after the pushing component moves into place, the positioning component resets and moves back, and the distance between the outer side of the pushing component and the end of the redundant short side of the vacuum insulation board is set to form a pressing area that facilitates the pressing component to move down and fix the pinching corner.

[0013] The positioning component includes an L-shaped plate with an inclined end face, and a guide plate with a triangular structure is fixed to the side of the L-shaped plate facing the vacuum insulation board.

[0014] Both the front and rear corner pinching mechanisms include a heat-pressing mechanism for heat-pressing and shaping a portion of the redundant short sides by means of frictional heat generation. The heat-pressing mechanism includes a heat-pressing plate that can be relatively movable and attached to the bottom surface of the L-shaped plate. When the L-shaped plate moves left and right on the redundant short sides, the heat-pressing plate moves relative to the L-shaped plate and generates heat through friction to heat-press and shape a portion of the redundant short sides.

[0015] The L-shaped plate includes a pressing part with a beveled front end and a mounting part extending rearward. The mounting part has an elongated hole penetrating both its upper and lower ends at its center. At least one positioning seat penetrating the elongated hole is fixedly attached to the hot-pressing plate. Shafts and sliders on both sides of the positioning seat cooperate with guide grooves recessed into the L-shaped plate, allowing the hot-pressing plate to be positioned and moved within the L-shaped plate. Corresponding elastic elements are mounted on both sides of the elongated hole on the L-shaped plate via fixing blocks. The ends of the elastic elements are fixedly attached to adjacent sliders. The outer end of the hot-pressing plate protrudes from the L-shaped plate with a beveled end face. A corresponding limiting element is fixedly attached to the lower side of the L-shaped plate without the beveled end face. When the pressing part moves outward towards the redundant short side, the hot-pressing plate moves inward under the action of the interaction force. After being blocked by the limiting element, its end face is flush with the end face of the L-shaped plate, and the elastic element is stretched.

[0016] The hot plate is made of mold steel and is treated by rusting and polishing until its surface is smooth and has evenly distributed pits.

[0017] Below both the front and rear pinching mechanisms are support mechanisms that provide support during the pinching action. Each support mechanism includes a set of support rods rotatably disposed between the two conveyor belts and a set of support seats that can be moved up and down and installed on the outside of the conveyor belts. When the vacuum insulation panel moves into place, the support rods rotate and stand upright below the redundant short side to support and limit the positioning component. The support seats move up and stand below the redundant short side to support the flattening component and the pressing component.

[0018] The outer side of the conveyor belt is equipped with a pressing block for fixing the vacuum insulation panel, which can move left and right, and a scraper is installed above the pressing block, which can move up and down and left and right.

[0019] Advantages of this utility model:

[0020] 1) This utility model improves the design of the cooperation between the positioning component, the flattening component, and the pressing component to achieve the pinching action. The positioning component flattens the redundant short side and forms a position through its beveled end. Then, when the flattening component pushes inward along the upper surface of the positioning component, it pushes the redundant long side inward along the bevel of the positioning component, forming an inward fold. After the positioning component moves into place, the distance between the outer side of the flattening component and the redundant short side end of the vacuum insulation board is set to form a pressing area that facilitates the downward movement of the pressing component to fix the pinched corner. The downward-moving pressing component then presses and fixes the folded corner to form a fold line. The pinching structure of this utility model is simpler, the operation is more convenient, and it is easier to implement.

[0021] 2) The pinching action affects the quality of the subsequent short edge fold and whether the redundant edge will protrude. Therefore, it is necessary to ensure the quality of the pinching. The flatness of the redundant short edge will affect the action of the flattening component. Based on this, a heat-pressing mechanism is added to the positioning component. The heat-pressing mechanism moves with the positioning component to heat-press and flatten the redundant short edge. However, due to the limitation of the setting position, it is not easy to install traditional heat-pressing equipment at this position, and the wiring connected to the traditional heat-pressing equipment will affect the movement of the positioning component. Therefore, this utility model sets a heat-pressing plate that can move relative to the bottom surface of the L-shaped plate of the positioning component. By using the left and right movement of the heat-pressing plate and the positioning component, the heat-pressing plate moves relative to the positioning component and generates heat through friction. While the positioning component flattens the redundant short edge, the redundant short edge is flattened by heat-pressing through friction. The hot ironing plate is connected to the positioning component by means of a slider and a guide groove, and the end of the hot ironing plate protrudes from the positioning component. During the pinching action, the hot ironing plate moves relative to the positioning component under the action of interaction force and is blocked by the limiting component. When the positioning component is reset, the hot ironing plate moves towards the positioning component under the dual action of interaction force and elastic force of elastic component and continues to generate heat through friction, thereby ensuring that the temperature of the hot ironing plate is maintained at 35-50℃, ensuring the hot ironing effect and the practical effect of this utility model.

[0022] 3) The hot stamping plate of this utility model is made of mold steel, preferably H13 type abrasive steel, which has high wear resistance and fast thermal conductivity. After rusting treatment, it is polished to a smooth surface with evenly distributed pits, so that the surface of the hot stamping plate not only has a smooth and flat surface to ensure that the hot stamping plate and the positioning parts can move relative to each other, but also increases the friction coefficient of the hot stamping plate, thereby increasing the friction heat generation temperature, ensuring the practical effect of self-heating of the hot stamping mechanism, realizing the hot stamping flattening of redundant short sides, and promoting the completion of the pinching action.

[0032] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0033] Example 1

[0034] refer to Figure 1-7 A redundant pinching device for an automated vacuum insulation panel production line, comprising:

[0035] A frame 1 is provided with a front-to-back transmission mechanism 2, which includes two synchronously operating conveyor belts 201 spaced apart from each other.

[0036] The front pinching mechanism 3 is installed at the discharge end of the front conveying mechanism 2 and is used to push the redundant long side folded part and the redundant short side connection point of the front side of the vacuum insulation board inward.

[0037] The rear pinching mechanism 4 is installed at the discharge end of the rear conveying mechanism 2. It is used to push the redundant long side folded part and the redundant short side connection point of the vacuum insulation board inward to form a pinching corner. It has the same structure as the front pinching mechanism 3. Both include two sets of symmetrical pinching components 5 that are synchronously driven and arranged on the outside of the two conveyor belts 201. The pinching component 5 includes a positioning member 501 and a flattening member 502 that are staggered vertically and move relatively. After the positioning member 501 is pressed and moved into place on the redundant short side, the flattening member 502 moves inward along the upper surface of the positioning member 501 and pushes the redundant long side inward along the positioning member 501 to form a pinching corner.

[0038] The outer end face of the positioning member 501 is inclined. After the positioning member 501 moves to the connection point of the redundant short side and the redundant long side, the pushing member 502 pushes the redundant long side to move inward along the inclined surface of the positioning member 501 to form an inwardly inclined side.

[0039] The pinching component 5 also includes a pressing component 503 that can be moved up and down and disposed on the outside of the pushing component 502; after the pushing component 502 moves into place, the positioning component 501 is reset and moved back, and the distance between the outer side of the pushing component 502 and the end of the redundant short side of the vacuum insulation plate is set to form a pressing area that facilitates the pressing component 503 to move down and fix the pinching corner.

[0040] This invention improves the design of the cooperation between components such as the positioning component 501, the flattening component 502, and the pressing component 503 to achieve a pinching action. The positioning component 501 flattens the redundant short side and forms a position through its beveled end. When the flattening component 502 pushes inward along the upper surface of the positioning component 501, it also pushes the redundant long side inward along the bevel of the positioning component 501, forming an inwardly inclined bevel, thus creating an inward fold. After the positioning component 501 moves into position, the distance between the outer surface of the flattening component 502 and the redundant short side end of the vacuum insulation board is set to form a pressing area that facilitates the downward movement of the pressing component 503 to fix the pinched corner. The downward movement of the pressing component 503 then presses and fixes the folded corner to form a fold line. This invention offers a simpler pinching structure, easier operation, and is easier to implement.

[0041] The positioning component 501 includes an L-shaped plate 5031 with an inclined end face, and a guide plate 5032 with a triangular structure is fixedly connected to the side of the L-shaped plate 5031 facing the vacuum insulation plate.

[0042] Below the front pinching mechanism 3 and the rear pinching mechanism 4, there is a support mechanism that provides support when pinching them. The support mechanism includes a set of support rods 7 rotatably disposed between the two conveyor belts 201, and a set of support seats 8 that can be moved up and down and installed on the outside of the conveyor belts 201. When the vacuum insulation panel moves into place, the support rods 7 rotate and stand upright below the redundant short side to support and limit the positioning member 501. The support seats 8 move up and stand below the redundant short side to support the flattening member 502 and the pressing member 503.

[0043] The outer side of the conveyor belt 201 is provided with a pressing block 9 for fixing the vacuum insulation panel, which can move left and right, and a scraper 10 is installed above the pressing block 9, which can move up and down and left and right.

[0044] Example 2

[0045] refer to Figure 8The difference between this embodiment and Embodiment 1 is that: both the front pinching mechanism 3 and the rear pinching mechanism 4 include a heat-pressing mechanism 6 for heat-pressing and shaping a portion of the redundant short sides by means of frictional heat generation. The heat-pressing mechanism 6 includes a heat-pressing plate 601 that can be relatively movable and attached to the bottom surface of the L-shaped plate 5031. When the L-shaped plate 5031 moves left and right on the redundant short sides, the heat-pressing plate 601 moves relative to the L-shaped plate 5031 and generates heat through friction to heat-press and shape a portion of the redundant short sides.

[0046] The L-shaped plate 5031 includes a pressing part with an inclined front end and a mounting part extending rearward. The mounting part has an elongated hole 11 penetrating both its upper and lower end faces at its center. At least one positioning seat 602 penetrating the elongated hole 11 is fixedly connected to the hot-pressing plate 601. The hot-pressing plate 601 is movable and positioned below the L-shaped plate 5031 by means of shafts and sliders 603 located on both sides of the positioning seat 602 cooperating with guide grooves recessed on the L-shaped plate 5031. The L-shaped plate 5031 is further secured by fixed... A corresponding elastic element 604 is installed on the fixed block. The end of the elastic element 604 is fixed to the adjacent slider 603. The outer end of the hot plate 601 protrudes from the L-shaped plate 5031 and its end face is set in a bevel. A corresponding limiting element 605 is fixed to the lower side of the L-shaped plate 5031 without the bevel. When the pressing member 503 moves to the outside of the redundant short side, the hot plate 601 moves inward under the action of the interaction force. After it moves into place and is blocked by the limiting element 605, its end is flush with the end of the L-shaped plate 5031, and the elastic element 604 is stretched.

[0047] The pinching action affects the quality of the subsequent short edge fold and whether the redundant edge will protrude. Therefore, it is necessary to ensure the quality of the pinching. The flatness of the redundant short edge will affect the action of the flattening component 502. Based on this, a heat-pressing mechanism 6 is added to the positioning component 501. The heat-pressing mechanism 6 moves with the positioning component 501 to heat-press and flatten the redundant short edge. However, due to the limitation of the setting position, it is not easy to install traditional heat-pressing equipment at this position, and the wiring connected to the traditional heat-pressing equipment will affect the movement of the positioning component 501. Therefore, this utility model sets a heat-pressing plate 601 that can move relative to the bottom surface of the L-shaped plate 5031 of the positioning component 501. By using the left and right movement of the heat-pressing plate 601 and the positioning component 501, the heat-pressing plate 601 moves relative to the positioning component 501 and generates heat through friction. While the positioning component 501 pushes flattened the redundant short edge, the redundant short edge is also flattened by heat-pressing through friction. The hot ironing plate 601 is connected to the positioning member 501 by means of a slider and a guide groove. The end of the hot ironing plate 601 protrudes from the positioning member 501. During the pinching action, the hot ironing plate 601 moves relative to the positioning member 501 under the action of the interaction force and is blocked by the limiting member 605. When the positioning member 501 is reset, the hot ironing plate 601 moves towards each other and resets under the dual action of the interaction force and the elastic force of the elastic member 604, and continues to generate heat through friction. This ensures that the temperature of the hot ironing plate 601 is maintained at 35-50℃, ensuring the hot ironing effect and the practical effect of this utility model.

[0048] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0049] Example 3

[0050] The difference between this embodiment and embodiment two is that the hot plate 601 is made of mold steel and is processed by rusting and polishing until its surface forms a smooth surface with evenly distributed pits.

[0051] The hot stamping plate 601 of this utility model is made of mold steel, preferably H13 type abrasive steel, which has high wear resistance and fast thermal conductivity. After rusting treatment, it is polished to a smooth surface with evenly distributed pits, so that the surface of the hot stamping plate 601 not only has a smooth and flat surface to ensure that the hot stamping plate 601 and the positioning part 501 can move relative to each other, but also increases the friction coefficient of the hot stamping plate 601, thereby increasing the friction heat generation temperature, ensuring the practical effect of the self-heating of the hot stamping mechanism 6, realizing the hot stamping and flattening of redundant short sides, and promoting the completion of the corner pinching action.

[0052] It should be noted that the implementation principle and technical effects of this embodiment are the same as those of Embodiment 2. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in Embodiment 2.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
