Description

Technical Field

[0001] This utility model relates to the field of edge sealing equipment technology, specifically to an automatic edge sealing device for nano-insulation boards. Background Technology

[0002] Nano-insulation panels are a type of high-efficiency thermal insulation material developed based on nanotechnology. Existing nano-insulation panels are used in various fields such as construction, metallurgy, and chemical engineering. Especially in the construction sector, they effectively isolate indoor and outdoor temperature transfer, improve building energy efficiency, reduce energy consumption for air conditioning and heating, and achieve energy conservation and emission reduction.

[0003] In the production process of nano-insulation panels, the side walls are usually sealed. Commonly used sealing materials are PVC or ABS plastic sealing strips. However, in the traditional bonding process, since the adhesive is mostly applied manually, it is not only time-consuming and labor-intensive, but also inefficient. Furthermore, the thickness of the adhesive is uneven, which can easily lead to bubbles or cracks, thus affecting the production quality of nano-insulation panels. Utility Model Content

[0004] Based on the above description, this utility model provides an automatic edge sealing device for nano-insulation boards, which solves the problem that the edge sealing of existing nano-insulation boards is mostly done manually, which is not only inefficient but also affects the production quality.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic edge-sealing device for nano-insulation panels includes a workbench. The top surface of the workbench is provided with a sealing base. A positioning groove is located at the center of the top surface of the sealing base. Rectangular openings are provided on the four side walls of the positioning groove. An extrusion component is provided inside each rectangular opening. The top surface of the sealing base is also provided with a feeding port, which communicates with the rectangular openings and sequentially feeds sealing strips inwards. The end of the extrusion component is attached to the back of the sealing strip and pushed towards the center of the positioning groove. A feeding assembly is also provided on one side of the top surface of the workbench. The feeding assembly holds a nano-insulation panel and is positioned directly above the positioning groove.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the extrusion component includes an electric push rod, which is disposed inside the packaging base. The telescopic end of the electric push rod extends toward the center of the positioning groove and is connected to a coating plate. The coating plate is generally elongated and has an injection tube on the side facing the positioning groove. The bottom of the coating plate has an inlet, which is connected to the storage tank through a pipe.

[0009] Furthermore, the edge sealing strip is a plastic sheet of the same length as the adhesive board, and the side of the edge sealing strip facing the positioning groove is provided with an injection groove, and the other side of the edge sealing strip is provided with an injection hole, and the injection groove and the injection hole are interconnected.

[0010] Furthermore, the glue injection tube is also equipped with a micro pump. When the electric push rod extends toward the positioning groove, the glue coating plate is attached to the back of the sealing strip, and the glue injection tube is inserted into the glue injection hole and injects the glue into the glue injection groove.

[0011] Furthermore, the glue injection groove is configured as a U-shaped groove with multiple channels, and the multiple channels of the glue injection groove are interconnected. A sealing gasket is also provided at the edge of the glue injection groove.

[0012] Furthermore, the feeding assembly includes a fixed frame vertically mounted on the top surface of the workbench. The top of the fixed frame is equipped with a turntable, and the fixed frame is equipped with a servo motor that drives the turntable to rotate. The bottom surface of the turntable is provided with four grippers on each of its four sides, one of which is located directly above the positioning groove.

[0013] Furthermore, the gripper includes a cylinder vertically mounted on the turntable, with an electric suction cup at the bottom of the cylinder. The cylinder extends downward to the electric suction cup, which engages with the top surface of the packaging base, and the nano heat insulation plate located at the bottom of the electric suction cup is attached to the bottom surface of the positioning groove.

[0014] Furthermore, a spring rod is provided at the center of the bottom surface of the positioning groove, and a support plate is provided on the top of the spring rod and is arranged horizontally.

[0015] Furthermore, pressure sensors are provided at the connection between the electric suction cup and the cylinder, as well as on the adhesive coating plate.

[0016] Furthermore, the interior of the adhesive-coated plate is also equipped with an electric heating wire.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. This application improves upon existing nano-insulation board packaging equipment by equipping the end face of the packaging strip with a U-shaped groove, which not only effectively avoids phenomena such as glue overflow, but also guides the delivery of adhesive liquid, making the adhesive liquid more evenly distributed on the end face of the packaging strip. This greatly improves the bonding strength between the packaging strip and the side wall of the nano-insulation board, ensuring the production quality of the nano-insulation board.

Detailed Implementation

[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] Combination Figure 1-5 As shown, an automatic edge-sealing device for nano-insulation panels includes:

[0029] Workbench 1 is the main installation body of the entire automatic edge banding equipment. It is placed on the ground by the bottom support corners, or it can be fixed on a horizontal platform.

[0030] The encapsulation base 2 is set on the top surface of the workbench 1 and is set in a rectangular structure. A positioning groove 21 is opened at the center of the top surface. The positioning groove 21 is used to place the nano heat insulation board and perform subsequent extrusion sealing.

[0031] The extrusion component 3 is located inside the encapsulation base 2. By lateral extrusion, the encapsulation strip is made to adhere to the side wall of the nano heat insulation board, thereby completing the edge sealing in conjunction with the glue injection process. This structure is a combination of an electric telescopic rod and a glue application plate 32.

[0032] The feeding component 4 is set on the workbench 1 to continuously feed the nano heat insulation board to the positioning groove 21 on the packaging seat 2, thereby accelerating the sealing efficiency of the nano heat insulation board.

[0033] Specifically, in this embodiment, a rectangular opening is provided on the side wall of the positioning groove 21 of the packaging base 2. A coating plate 32 is placed inside the rectangular opening. The coating plate 32 is set as a strip and its length is set to be the same as the side wall of the produced nano heat insulation board. On the side of the coating plate 32 away from the positioning groove 21, an electric push rod 31 should also be provided. The electric push rod 31 can be selected according to the side extrusion force, and the electric push rod 31 with the corresponding force in the DT series can be used to push it towards the positioning groove 21. In order to ensure uniform pushing force, especially when the side wall of the nano heat insulation board is long, the number of electric push rods 31 should be appropriately increased to ensure that the coating plate 32 slides smoothly inside the rectangular opening and the side wall of the nano heat insulation board is subjected to uniform force.

[0034] Based on the above structure, the top surface of the encapsulation base 2 is also provided with a feeding port 22. The feeding port 22 extends downward and communicates with the rectangular opening. The length of the feeding port 22 should be the same as the length of the corresponding edge sealing strip. It is mainly used to transport the pre-cut edge sealing strip 5 into the rectangular opening, and then, together with the adhesive plate 32, its side wall is attached to the side wall of the nano heat insulation board.

[0035] In actual production, the method of applying adhesive before bonding can easily cause the adhesive to be squeezed, resulting in excess adhesive overflowing from the bonding area. This overflow can easily lead to subsequent sealing failure. Moreover, after curing, the overflow can form irregular glue nodules, causing local stress concentration. Therefore, in order to avoid this problem, this embodiment adopts the method of bonding first and then applying adhesive.

[0036] Therefore, in the above structure, the coating plate 32 should be hollow, and at least one glue injection pipe 33 should be provided on the side facing the positioning groove 21 (when the coating plate 32 is long, multiple glue injection pipes 33 are provided). The glue injection pipe 33 is connected to its internal space. An inlet 34 is also provided on one side of the coating plate 32. The inlet 34 is connected to the storage tank through a pipe. The storage tank is used to store neoprene glue so that the glue liquid inside the coating plate 32 can be replenished periodically by a water pump or other conveying equipment.

[0037] The side of the encapsulation strip facing the positioning groove 21 is the front side, and there is a glue injection groove on its side wall. There are multiple glue injection grooves that are interconnected and are all U-shaped grooves with a square structure. They are mainly used to guide the glue to spread in all directions, so that the glue is more evenly distributed on the side wall of the encapsulation strip. In the subsequent bonding process, the glue injection groove can hold excess glue, which can effectively prevent glue overflow caused by excessive glue injection.

[0038] The side of the encapsulation strip away from the positioning groove 21 is the back side, and a glue injection hole is provided on the back side. This glue injection hole is connected to the glue injection groove. When the encapsulation strip is fed into the rectangular opening through the top feeding port 22, the electric telescopic rod pushes the coating plate 32 to move outward, so that the glue injection tube 33 on the coating plate 32 is inserted into the glue injection hole on the encapsulation strip. Then, it is continuously squeezed outward, and finally the encapsulation strip is attached to the side wall of the nano heat insulation board. In the above process, this insertion method can also use the coating plate 32 to position the edge sealing strip 5, preventing the edge sealing strip 5 from shaking or tilting, thereby effectively ensuring the encapsulation production quality of the nano heat insulation board.

[0039] An additional electric heating wire should be installed inside the coating plate 32 to preheat the chloroprene rubber solvent by electric heating. This can increase the viscosity of the chloroprene rubber when it is injected, improve its fluidity, ensure that it can fill the injection tank, prevent air bubbles, and enhance the adhesion strength between the sealing strip and the nano heat insulation board. It can also heat the solvent to evaporate, thereby increasing the curing speed. The heating temperature should be maintained at 60-70℃ to avoid the glue from forming a skin due to violent solvent evaporation. The time for the glue to rise from room temperature to the target temperature should be controlled within 10-30 minutes. Within this time period, the glue temporarily stored inside the coating plate 32 must be used up and then replenished through an external storage tank to prevent rubber oxidation caused by prolonged heating.

[0040] A micro pump 35 should be equipped on the glue injection tube 33 of the glue coating plate 32. The micro pump 35 can be a syringe pump WX-74200 or a CFSP-I / CU-I constant flow injection pump, etc., and is connected to an external controller via a wire so that the operator can control the injection volume.

[0041] To further improve the edge sealing effect, elastic pads can be installed on the top surface of both sides of the glue injection groove. These elastic pads can be rubber pads, and V-shaped grooves are arranged on the top surface of the elastic pads. By squeezing, the elastic pads and the end face of the nano heat insulation board are squeezed together to form multiple sealed spaces, thereby forming a multi-layer sealing structure with neoprene glue. This greatly enhances the edge sealing effect of the entire nano heat insulation board and effectively extends the service life of the nano heat insulation board.

[0042] Furthermore, during the aforementioned clamping and dispensing process, it is necessary to maintain pressure for 3-5 hours. To prevent glue leakage due to insufficient pressure or damage to the encapsulation strip due to excessive pressure, pressure sensors should be installed on the dispensing plate 32. These pressure sensors use SBT673 small sensors to measure the pressure on one side and transmit the detection data to the control center via Bluetooth module or wire. This allows the operator to control the electric telescopic rod to ensure that the pressure on the opposite side is the same and remains within a fixed range.

[0043] The workbench 1 is also equipped with a feeding assembly 4, which includes a vertically arranged fixed frame 41. A turntable 42 is movably mounted on the top of the fixed frame 41 using a bearing structure. A servo motor 43 is also embedded on the top of the fixed frame 41. The servo motor 43 is preferably a Siemens 1FT7 servo motor 43 and is located at the center of the bearing, so that its output end is fixedly connected to the center of the bottom surface of the turntable 42, thereby driving the entire turntable 42 to rotate. Its power supply wire extends outward and is connected to the control center for easy programming control to ensure that the single rotation is 90°, thereby cooperating with other components to complete the edge sealing work.

[0044] The turntable 42 is also equipped with grippers, which consist of cylinders 44 and electric suction cups 45. The cylinders 44 can be QTB two-stage telescopic cylinders 44 or SMC C96SDB50-160C series remotely controllable cylinders 44, each equipped with its own battery, or connected to an external circuit via wires. Four cylinders 44 are fixedly mounted on the turntable 42, arranged in a circular array. Four electric suction cups 45 are also provided, each fixedly mounted at the bottom of the telescopic end of a cylinder 44. These electric suction cups 45 can be Winhua Machinery XP-606, Zhengxinda DP-X6P, or MYC108. The machine-mounted remote suction cup controller is equipped with electromagnetic suction cups and other components, and is also equipped with a separate battery for independent power supply, or it can be connected to an external power supply circuit through wires. By lifting and coordinating with the rotation of turntable 42, the suction cup is brought close to the loading station, and the unsealed nano heat insulation board is firmly sucked up by electric suction cup 45. Then it is moved to the top of the sealing base 2, extends downward, and fits into the positioning groove 21. During the sealing process, it is continuously pressed downward until the sealing is completed. At the same time, in order to prevent excessive pressure applied from the top downward, a pressure sensor should be added at the connection between electric suction cup 45 and cylinder 44 so as to control the downward extension length of cylinder 44 by the downward pressure.

[0045] Furthermore, during the aforementioned edge sealing process, the seal should be attached with... Figure 4The structure shown is such that the left and right sides are slightly longer, while the front and back sides are equal in length to the sidewalls of the nano-insulation board. Therefore, the two slightly longer sealing strips 5 can cover the end faces of the front and back sealing strips 5. Furthermore, additional snap-fit ​​structures can be added to the end faces of the sealing strips 5, or adhesive can be introduced into the connection area through grooves. Through the adhesion of the adhesive, the four sealing strips 5 are connected as a whole, achieving a one-time sealing and avoiding subsequent processing of the corners, greatly improving the sealing efficiency of the entire nano-insulation board. Therefore, in the actual sealing process, the slightly shorter sealing strips 5 at the front and back ends should be attached to the nano-insulation board, and then the slightly longer sealing strips 5 on the left and right sides should be attached to the other two sides to complete the sealing.

[0046] After the sealing is completed, the electric suction cup 45 will be released, and the cylinder 44 will retract. In order to facilitate the staff to take out the sealed nano heat-sealing plate, a groove can also be provided at the center of the bottom surface of the positioning groove 21, and a spring rod 23 is installed inside the groove. The top of the spring rod 23 is provided with a support plate and is arranged horizontally. When the spring rod 23 retracts to the minimum stroke, the support plate is flush with the bottom surface of the positioning groove 21.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
