Description

Technical Field

[0001] The present invention relates to the technical field of heat insulation material processing, and particularly relates to a follow-up edge folding device for a vacuum insulation panel. Background Art

[0002] Due to the diverse models and styles of vacuum insulation panels, the general automation level in the industry is not high; as a new material, many processes are carried out manually, especially the edge folding process. During the production of vacuum insulation panels, in order to facilitate the bagging of the core material, the designed width dimension of the film bag is larger than the width of the core material. After the core material is bagged and subjected to vacuum treatment, after the vacuum process, it is necessary to fold the excess film bags on both sides of the vacuum insulation panel (that is, turn the film bag over to the upper end face of the vacuum insulation panel) to ensure the state and size of the vacuum insulation panel. In the industry, the edge folding process is basically completed manually, with high manual labor intensity, low production efficiency, large labor demand, and difficult to guarantee product quality, making this process a bottleneck in traditional production, restricting the production capacity of the front and back processes, and the production efficiency cannot match the front and back processes. Due to the lag of this process, it is necessary to frequently remove the products from the production line and stack them in the front end to keep the previous process running continuously, increasing ineffective operations and product costs; for the above reasons, enterprises need relatively large labor and management costs to maintain this production process.

[0003] At present, the automatic edge folding equipment on the market has problems such as slow production rhythm and low output, and cannot achieve the production plan target. Summary of the Invention

[0013] Further, the transmission portion includes a transmission shaft mounted on the output end of the first driving member. A transmission gear is mounted on the transmission shaft, and the transmission gear is meshed and connected with a first rack located on at least one side of the follower plate.

[0014] Further, the pressing plate mechanism includes a first adjusting component and a pressing plate component;

[0015] The first adjusting component is connected to the follower plate, and the pressing plate components are mounted on both sides of the first adjusting component;

[0016] The first adjusting component is used to adjust the distance between the two pressing plate components according to the width of the vacuum insulation panel;

[0017] The pressing plate component is used to press the vacuum insulation panel.

[0018] Further, the first adjusting component includes a second driving member mounted on the follower plate. A first lead screw is mounted on the output end of the second driving member.

[0022] The second adjusting component is used to adjust the distance between the two hemming components according to the width of the vacuum insulation panel and adjust the height of the two hemming components according to the thickness of the vacuum insulation panel;

[0023] The hemming component is used to fold the film bags on both sides of the vacuum insulation panel.

[0024] Further, the second adjusting component includes a third driving member mounted on the bottom of the follower plate.

[0027] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0028] The vacuum insulation panel of the present invention enters this device through the conveying mechanism. The vacuum insulation panel is conveyed forward under the conveying action of the conveying mechanism. When the vacuum insulation panel completely enters the hemming mechanism, the follower mechanism starts to drive the follower plate to move, thereby driving the pressing plate mechanism and the hemming mechanism to move, gradually making the moving speed of the follower plate consistent with the moving speed of the conveying mechanism. Then, the vacuum insulation panel is pressed by the pressing plate mechanism and moves forward as a whole following the conveying mechanism. The hemming mechanism starts to fold the redundant film bags on both sides of the vacuum insulation panel and folds the film bags to the upper end face of the vacuum insulation panel. After hemming is completed, the pressing plate mechanism releases the vacuum insulation panel, and the follower mechanism drives the follower plate to quickly return to the origin position, waiting for the next vacuum insulation panel to enter this station for hemming; the entire hemming work is completed during the conveying process of the vacuum insulation panel, making the entire hemming process flow and continuous, solving the bottleneck in traditional production, improving production efficiency, and having a relatively high degree of automation.

[0055] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0056] The terms "first", "second", "third", "fourth", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", "third", "fourth", etc. are usually of the same category, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0057] In the actual use process, the inventor found that the current automatic hemming equipment on the market adopts a step single-station mode. After the product reaches this station, the production line needs to stop transporting the product so that the equipment can complete the hemming. This kind of equipment has a slow production beat and low output, and cannot complete the production plan target.

[0058] The following combines the attached Figures 1 to 17 to elaborate in detail on a vacuum insulation panel follow-up hemming device provided by this application through specific embodiments and their application scenarios.

[0059] A vacuum insulation panel follow-up hemming device includes: a conveying mechanism 100, a follow-up plate 200, a follow-up mechanism 300, a pressing plate mechanism 400, and a hemming mechanism 500;

[0060] The conveying mechanism 100 is used to convey the vacuum insulation panel 10;

[0061] Specifically, referring to Figure 1 and Figure 2 This application has a workbench 20 placed on the ground. On both sides in the width direction of the workbench 20, there are slidingly installed moving tables 30. At one end where the two moving tables 30 are close to each other, there is a conveying mechanism 100 installed, that is, there are 2 conveying mechanisms 100. The bottom of both sides in the width direction of the vacuum insulation panel 10 is in contact with the conveying mechanism 100;

[0062] Referring to Figure 3 and Figure 4, a second rack 32 is installed along the width direction of the workbench 20. On both sides of the second rack 32, fourth linear guide rails 33 parallel to the second rack 32 are symmetrically arranged. The bottom of the moving tabletop 30 is slidably connected to the fourth linear guide rails 33 through sliders, which improves the stability of the movement of the moving tabletop 30. A second motor 31 is vertically installed on the moving tabletop 30. The output shaft of the second motor 31 penetrates through the moving tabletop 30 and is equipped with a gear meshed with the second rack 32. The output shaft of the second motor 31 is rotatably connected to the moving tabletop 30. Rollers are rotatably installed on both sides at both ends of the moving tabletop 30. Horizontal plates parallel to the second rack 32 are arranged on both sides of the workbench 20. The rollers are in contact with the horizontal plates, which improves the smoothness of the movement of the moving tabletop 30; the second motor 31 makes the moving tabletop 30 move along the width direction of the workbench 20 through the meshing of the gear and the second rack 32, and adjusts the distance between the two conveying mechanisms 100 to adapt to the width change of different widths of the vacuum insulation board 10.

[0063] Among them, the second motor 31 can be a stepping motor or a servo motor.

[0064] Referring to Figure 8 , the conveying mechanism 100 includes a support plate 110 arranged along the length direction of the workbench 20. The support plate 110 is made of aluminum profile. The support plate 110 is installed on the moving tabletop 30 through a plurality of L-shaped fixing brackets. Installation plates are installed at both ends of the support plate 110. Synchronous belt pulleys 120 are rotatably connected to the installation plates. A synchronous belt 130 is sleeved outside the two synchronous belt pulleys 120 and the support plate 110. A first motor 140 is installed on one of the installation plates. One of the synchronous belt pulleys 120 is driven by the first motor 140, so as to drive the synchronous belt 130 to move, and further convey the vacuum insulation board 10 placed on the synchronous belt 130; the two synchronous belts 130 form a workbench surface, and hemming and pasting are both completed on this workbench surface. This mechanism can continuously convey the incoming material to the next station, and at the same time serve as a support platform for the hemming action.

[0065] Among them, the first motor 140 can be a stepping motor or a servo motor.

[0066] After the vacuum insulation panel is processed at the front-end station, the excess film bags on both sides are in an upward state. The front-end station is existing equipment, specifically the edge-lifting plates in a continuous edge-folding device for a vacuum insulation panel with the application number CN202510405868.8. There are 2 edge-lifting plates. The lower corner of the edge-lifting plate can be a right angle, and the upper part has an arc transition. The top of edge-lifting plate 1 is gradually inclined upward along the conveying direction of the conveying mechanism 100, and the inclination angle at its top is about 15°. The height of its front end is lower than the top surface height of the synchronous belt 130, and the height of its end is greater than the top surface height of the synchronous belt 130 and the maximum thickness of the vacuum insulation panel 10 (the thickness of the vacuum insulation panel 10 varies in the range of 5 - 30 mm). The distance between the two edge-lifting plates is 4 - 8 mm greater than the width of the vacuum insulation panel 10, ensuring a gap for the subsequent film bag for spraying glue. By setting the edge-lifting plates, the curled and downward-turned film bags are lifted upward to a vertical state.

[0067] Referring to Figure 1 and Figure 2 , the follower plate 200 is arranged corresponding to the conveying mechanism 100 and moves along the length direction of the conveying mechanism 100;

[0068] Specifically, several columns 40 are installed on both sides along the length direction of the workbench 20, and the top of several columns 40 is installed with the same frame 50. The frame 50 is arranged in a square shape; both the columns 40 and the frame 50 are made of aluminum profiles; the first linear guide rails 60 are installed at both ends of the frame 50 along the length direction of the workbench 20. The two sides of the bottom of the follower plate 200 are slidably connected to the first linear guide rails 60 through sliders, improving the stability of the movement of the follower plate 200. In this embodiment, the follower plate 200 is designed with a frame structure in the shape of a Chinese character 'tian'; the follower plate 200 is located directly above the conveying mechanism 100; the follower plate 200 can move back and forth along the length direction of the conveying mechanism 100.

[0069] Referring to Figure 1 and Figure 2 , the follower mechanism 300 is connected to the follower plate 200 and is used to drive the follower plate 200 to move; so that the moving speed of the follower plate 200 is consistent with the moving speed of the synchronous belt 130 or drive the follower plate 200 to return to the origin position.

[0070] Referring to Figure 1 and Figure 2 , the pressing plate mechanism 400 is connected to the follower plate 200, moves along with the follower plate 200, and is used to press the vacuum insulation panel 10; in this embodiment, there are 2 pressing plate mechanisms 400, symmetrically arranged on both sides of the follower mechanism 300;

[0071] Referring to Figure 1 and Figure 2, the hemming mechanism 500 is connected to the follower plate 200 and is used to fold the film bags on both sides of the vacuum insulation panel 10, that is, to gradually push the film bags on both sides of the vacuum insulation panel 10 from a vertical state to a horizontal state where they are attached to the upper end surface of the vacuum insulation panel 10.

[0072] Specifically, the hemming mechanism 500 folds the excess film bags on both sides in the width direction of the vacuum insulation panel 10.

[0073] The follower plate 200, the follower mechanism 300, the pressing plate mechanism 400, and the hemming mechanism 500 of the present invention are integrally designed and installed to ensure that the follower plate 200 finally maintains the same moving speed as the conveying mechanism 100 under the drive of the follower mechanism 300. Through the pressing method of the pressing plate mechanism 400, the hemming mechanism 500, the vacuum insulation panel 10, and the conveying mechanism 100 are in a relatively static state, providing a stable working condition for hemming. At the same time, the three still move forward at the same speed, so that the vacuum insulation panel 10 will not stop on the production line, and the hemming rhythm matches the conveying speed rhythm of the vacuum insulation panel 10. There is no pause or offline during the hemming process, making the entire production line more streamlined and greatly improving the efficiency.

[0074] Among them, referring to Figures 1 to 4 , in this embodiment, there is also a glue spraying mechanism 600 located on both sides of the inlet end of the conveying mechanism 100. The glue spraying mechanism 600 includes a glue spraying head 620 located above the conveying mechanism 100. Specifically, the glue spraying head 620 is installed on one side of the moving table 30 through a fixed bracket. There is a hot melt adhesive machine 610 on one side of the conveying mechanism 100. The hot melt adhesive machine 610 can be placed on the ground. A hot melt adhesive pipe 630 is connected between the hot melt adhesive machine 610 and the glue spraying head 620.

[0075] Specifically, the fixed bracket is arranged in a Z shape; the hot melt adhesive machine 610 is an existing device with a pressure device inside, which can press the hot melt adhesive into the glue spraying head 620 through the hot melt adhesive pipe 630 to spray glue on the surface of the gap between the vacuum insulation panel 10 and the film bag. The glue spraying head 620 is fixed and does not need to adjust the height because the thickness change range of the vacuum insulation panel 10 is 5 - 30 mm, and the influence on the glue spraying range can be ignored; the hot melt adhesive pipe 630 can be telescopic; the glue spraying time can be detected by a sensor. When the sensor detects that the vacuum insulation panel 10 passes through the glue spraying head 620, the glue spraying mechanism 600 sprays hot melt adhesive on the surface of the vacuum insulation panel 10. When the vacuum insulation panel 10 is about to completely pass through the glue spraying mechanism 600, the glue spraying stops to prevent the hot melt adhesive from spilling onto the equipment; the glue spraying mechanism 600 sprays hot melt adhesive in advance at the position where hemming is required, so that after hemming, the excess film bags can be firmly adhered to the surface of the vacuum insulation panel 10; the glue spraying mechanism 600 cooperates with the corresponding sensor to realize automatic adjustment of the glue spraying duration, with uniform, fast, and continuous spraying.

[0076] Reference Figure 3 In this embodiment, the follower mechanism 300 includes a first driving member 310 and a transmission portion 320. The first driving member 310 is mounted on the follower plate 200, and the first driving member 310 drives the transmission portion 320 to drive the follower plate 200 to move.

A transmission gear 322 is mounted on the transmission shaft 321. The transmission gear 322 is meshed and connected with a first rack 323 located on at least one side of the follower plate 200. The first rack 323 is arranged along the length direction of the conveying mechanism 100.

[0079] Specifically, transmission shafts 321 are mounted on the output ends on both sides of the first driving member 310; connecting frames 70 along the length direction of the workbench 20 are mounted on both side edges of the frame 50 in the width direction of the workbench 20. A first rack 323 is mounted on the top of the connecting frame 70; and baffles 80 along the length direction of the workbench 20 are mounted on both side edges of the frame 50 in the width direction of the workbench 20. The baffles 80 have grooves inside. The transmission gear 322 and the first rack 323 are located in the grooves. The transmission gear 322 and the first rack 323 are protected by the baffles 80; the first driving member 310 drives the transmission gear 322 to move along the first rack 323, so that the follower plate 200 can move uniformly or quickly along the conveying direction of the conveying mechanism 100.

[0094] Refer to Figure 4 and Figure 7, in this embodiment, the hemming assembly 520 includes a rotating member 521 mounted on the third moving plate 516. A rotating shaft 522 is mounted on the rotating end of the rotating member 521. A plurality of driving arms 523 are mounted on the rotating shaft 522. A fixing plate 524 is mounted on the third moving plate 516 below the rotating shaft 522. One end of the fixing plate 524 close to the conveying mechanism 100 is rotatably connected with a movable plate 525. A plurality of fixing blocks 526 are mounted on the side of the movable plate 525 away from the conveying mechanism 100. A guiding hole 527 is formed in the fixing block 526.

[0095] Specifically, at least one rotating member 521 is mounted on the lower part of the sides of the two third moving plates 516 close to each other. In this embodiment, rotating members 521 are mounted on the lower parts of the sides of the two third moving plates 516 close to each other; the rotating member 521 can be a rotating cylinder or a motor, preferably a rotating cylinder; the same rotating shaft 522 is connected between the rotating ends of the two rotating members 521; a fixing plate 524 is mounted on the lower part of the sides of the two third moving plates 516 close to each other, and the fixing plate 524 can be L-shaped or concave; the movable plate 525 and the fixing plate 524 can be hinged; the fixing block 526 can be designed in a waist shape; every two fixing blocks 526 correspond to one driving arm 523; the guiding hole 527 is designed as a waist-shaped hole; the connecting rod 528 is located in the guiding hole 527.

[0096] The rotating member 521 drives the rotating shaft 522 to rotate, thereby driving the driving arm 523 to rotate. The driving arm 523 drives the connecting rod 528 to move in the guiding hole 527, so that the fixing block 526 and the movable plate 525 rotate with respect to the fixing plate 524, causing the movable plate 525 to press down on the vertical film bag and fold the film bag onto the upper end surface of the vacuum insulation panel 10.

[0097] Refer to Figure 1 and Figure 2 , in this embodiment, an electric control cabinet 90 is provided on one side of the workbench 20; the electric control cabinet 90 contains various electrical components, system programs, operation panels, etc., controls the entire device to execute actions according to a predetermined program, processes various sensors and signal sources, and outputs corresponding program instructions. The operator can input the data of the vacuum insulation panel 10 into the system program through an external touch screen. At the same time, external indicator lights and alarm lights display the operating state of the device, and external buttons can pause or emergency stop the operation of the device.

[0098] In this embodiment, the models of the first driving member 310, the second driving member 411, and the third driving member 511 are NMRV040╱10╱60╱B3.

[0099] In this embodiment, the electric control cabinet 90, the first driving member 310, the second driving member 411, the third driving member 511, the first motor 140, the second motor 31, the hot melt adhesive machine 610, the height adjustment module 515, the telescopic member 421, and the rotating member 521 are all prior arts.

[0100] Working principle: Before hemming, the operator can input the length, width, and thickness data of the vacuum insulation panel 10 into the system program through an external touch screen. According to this parameter, specifically according to the width of the vacuum insulation panel 10, the second driving member 411 is started. The second driving member 411 drives the first lead screw 412 to rotate, thereby adjusting the distance between the two first moving plates 413 on the two relative first lead screws 412. At the same time, the second motor 31 is started. The second motor 31 meshes with the second rack 32 through a gear to move the moving table 30 in the width direction of the workbench 20, adjust the distance between the two conveying mechanisms 100, and at the same time adjust the position of the glue spraying head 620 so that the glue spraying head 620 can be located directly above both ends of the vacuum insulation panel 10 in the width direction; according to the thickness of the vacuum insulation panel 10, the height of the third moving plate 516 is adjusted through the height adjustment module 515 so that when the movable plate 525 is turned over and horizontal, it can contact the upper end surface of the vacuum insulation panel 10. After the vacuum insulation panel 10 is processed at the front-end station, the excess film bags on both sides are in an upward state;

[0101] Refer to Figure 9 , Glue spraying station: The vacuum insulation panel 10 enters this device through the synchronous belt 130. The sensor detects that the vacuum insulation panel 10 enters the glue spraying mechanism 600, and the hot melt adhesive machine 610 is started. The hot melt adhesive is pressed into the glue spraying head 620 through the hot melt adhesive pipe 630 to spray the hot melt adhesive on the surface of the vacuum insulation panel 10. When the vacuum insulation panel 10 is about to completely pass through the glue spraying mechanism 600, the glue spraying stops;

[0102] Refer to Figure 10 , Following station: The vacuum insulation panel 10 continues to be conveyed forward under the conveying action of the synchronous belt 130. When the vacuum insulation panel 10 completely enters the hemming mechanism 500, that is, when both sides in the width direction of the vacuum insulation panel 10 just correspond to the hemming assembly 520, the first driving member 310 is started. The first driving member 310 drives the transmission shaft 321 to rotate, thereby driving the transmission gear 322 to rotate, so that the transmission gear 322 moves along the first rack 323, and then drives the follower plate 200 to move, thereby driving the pressing plate mechanism 400 and the hemming mechanism 500 to move, slowly accelerating, and gradually making the moving speed of the follower plate 200 consistent with the moving speed of the synchronous belt 130;

[0103] Refer to Figure 11 and Figure 12, Pressing plate station: Then the pressing plate 424 is pressed down by the telescopic member 421 to press the vacuum insulation panel 10, and the whole (i.e. the follower plate 200, the follower mechanism 300, the pressing plate mechanism 400 and the folding mechanism 500) moves forward following the synchronous belt 130;

[0104] Reference Figures 13 to 17 , Folding station: Then, according to the width of the vacuum insulation panel 10, the third driving member 511 is started, and the third driving member 511 drives the second screw rod 512 to rotate, so as to adjust the distance between the two second movable plates 513, and adjust the distance between the pressing plate assemblies 420, and then the rotating shaft 522 is driven to rotate by the rotating member 521, thereby driving the driving arm 523 to rotate, and the driving arm 523 drives the connecting rod 528 to move in the guide hole 527, so that the fixed block 526 and the movable plate 525 rotate with the fixed plate 524, so that the movable plate 525 presses down the vertical film bag, folds the film bag to the upper end surface of the vacuum insulation panel 10, so that it is closely fitted with the hot melt adhesive. After the folding is completed, the telescopic member 421 drives the pressing plate 424 to retract, releases the vacuum insulation panel 10, and the first driving member 310 reverses, driving the follower plate 200 to quickly return to the original position, waiting for the next vacuum insulation panel 10 to enter this station for folding.

[0105] The entire folding work of the present invention is completed during the conveying process of the vacuum insulation panel 10, so that the entire folding process is streamlined and continuous, so that the vacuum insulation panel 10 will not stop on the production line, making the entire production line more streamlined and the efficiency greatly improved;

[0106] The present invention realizes the online folding of the vacuum insulation panel 10, so that the entire folding process of the vacuum insulation panel 10 is streamlined and continuous, which solves the bottleneck in traditional production, improves production efficiency, and has a high degree of automation;

[0107] The folding rhythm of the present invention matches the conveying speed rhythm of the vacuum insulation panel 10, and the folding process has no pause or offline, thereby improving production efficiency;

[0108] The present invention reduces the interference of operators on the equipment. Operators only need to import the relevant data parameters of the vacuum insulation panel 10 into the system program. All mechanism actions are controlled by the electric control cabinet 90, which reduces the labor intensity, optimizes the number of workers, reduces product costs, improves product quality, and increases product competitiveness.

[0109] The present invention reduces the number of product circulation times and reduces the probability of product quality problems occurring during the transportation process.
