Description

Technical Field

[0001] The invention relates to the technical field of glass wool board production, and in particular to an automatic unloading and packaging mechanism for glass wool boards. Background Art

[0002] Glass wool board is a thermal insulation material made of glass fiber, which is spun into cotton after being melted at high temperature, and then heat-cured into a board. This material is mainly made of quartz sand, soda ash, sodium carbonate, limestone and other raw materials, which are melted at high temperature, fiberized by centrifugal blowing process, and sprayed with thermosetting resin to make filamentary materials, and finally processed into board products.

[0003] In the production process of glass wool boards, they need to be stacked and automatically unloaded at a designated position to complete packaging. The packaging process of glass wool boards is carried out by a specific packaging device. For example, a glass wool board packaging system with a publication number of CN 209080279U includes a glass wool board packaging machine, a first transmission device for feeding processed glass wool boards, and a third transmission device for conveying the packaged glass wool boards away. A second transmission device is arranged between the first transmission device and the glass wool board packaging machine, and a stacking structure for stacking the glass wool boards conveyed by the first transmission device in batches is arranged on the second conveyor belt.

[0004] During the production process of glass wool board, due to its fluffy open-pore fiber structure, if the edge is not properly handled, the fibers are easy to fall off. This will not only affect the overall aesthetics of the glass wool board. Therefore, during the packaging process, it is necessary to coat the sides of the glass wool board and trim the edges to ensure that the edges are neat and free of loose fibers. At the same time, the coating can enhance the stability of the overall structure of the glass wool board. Through cutting, edge pressing or edge sealing, the edges can be made stronger, reducing the performance degradation caused by edge damage or tearing during use, and preventing the packaging film from being cut during subsequent packaging. However, this packaging system lacks the process of trimming and coating the sides of the glass wool board, which reduces the packaging accuracy and affects the product quality. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the glass panels of the above-mentioned background technology are not coated and trimmed on the sides to clean the fibers during the unloading and packaging process, thereby affecting the quality of the packaged products, and to propose an automatic unloading and packaging mechanism for glass wool panels.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0036] When using this automatic unloading and packaging mechanism for glass wool boards, the glass wool boards are transported through an external conveying device. The conveying device transports the glass wool boards to the conveyor belt 11 of the return structure 1. While the conveyor belt 11 drives the glass wool boards to move, the glass wool boards will first contact the limit plates 12 on both sides. The limit plates 12 on both sides assist in returning the glass wool boards moving between them, so that the glass wool boards move to the center position and are transported from the return structure 1 to the coating structure 2. The drive boxes 21 on both sides control the rotation of the transport rollers 22, and the transport rollers 22 drive the glass wool boards above to move. At this time, the two sides of the glass wool board are in contact with the rotating wheels 25, and the rotating wheels 25 position and limit the position of the glass wool board. At this time, the hot air units 211 on both sides are started, and the exhaust ports 212 of the hot air units 211 on both sides blow out from the gaps of the rotating wheels 25, directly blowing and contacting the sides of the glass wool boards. Thus, the remaining loose fibers on the side of the glass wool board are blown off; the exhaust port 212 can also blow off the fibers on the front and rear sides of the glass wool board, and the blown fibers can be directly discharged from the gap between the lower transport rollers 22. The convection setting of the exhaust ports 212 on both sides prevents the fibers from entering the dead corners of the device. The coating structure 2 cleans the fibers on the side of the glass panel in the first half of the conveying, and then the glass fibers move to the area of ​​the coating box 28. The transfer cotton 210 on the top surface of the coating box 28 is dipped in the coating liquid, and the surface of the rotating wheel 25 contacts and rotates and rubs with the transfer cotton 210 during the rotation process, so that the surface of the rotating wheel 25 is contaminated with the coating liquid. During the transportation process, the rotating wheel 25 applies the coating liquid to the two sides of the glass wool board, and the coating is evenly applied during the transportation process. The upper hot air unit 211 can blow hot air to the side of the glass wool board through the rotating wheels 25, thereby accelerating the molding speed of the coating on the side of the glass wool board to make it quickly set. The surface of the rotating shaft 26 above the rotating wheel 25 is provided with a plurality of windshields 27. The air blown from the air outlet can contact the windshield 27 to drive the corresponding rotating wheel 25 to perform auxiliary rotation, thereby providing a force to the rotating wheel 25 to assist in the transportation of the glass limit plate 12. After the coating on both sides is completed, the glass wool board moves to the transfer structure 3. The cylinder 32 of the transfer structure 3 drives the push plate 33 to squeeze and move the side of the glass wool board. The glass wool board moves to the transport roller 22 of another coating structure 2 through the auxiliary return of the return groove 31. The new coating structure 2 directly performs the above-mentioned coating operation on both sides. Since the side fibers have been blown off before, the coating structure 2 directly coats the remaining two sides of the glass panel. The coated glass wool board is then transported to the buffer structure 4. The buffer slope 41 of the buffer structure 4 will slowly move the glass panel to the packaging groove 51 of the packaging box 5 on one side. Previously, the packaging film is manually placed under the pressing plate 7 , and the pressing plate 7 drives the packaging film to move downward into the packaging groove 51 for pressing and laying, and the edge of the packaging film close to the coating structure 2 is flush with the packaging groove 51 .Wait for the designated number of glass wool panels to be stacked on the packaging film of the lifting plate 56, and then manually drive the three sliding plates 52 to slide. The transmission rollers 53 at one end of the three sliding plates 52 contact the packaging film, so that the packaging film with the glass wool panels is laid flat in sequence. Then the driving rod 6 above drives the pressing plate 7 to press down. When the pressing plate 7 contacts the transmission roller 53, the transmission roller 53 rotates and drives the sliding plate 52 to slide outward, and the transmission roller 53 moves to the clearance groove 55 for storage. The pressing plate 7 presses the packaging film of the lower glass panel to complete the tight installation, and then the output end of the hydraulic cylinder 57 below drives the lifting plate 56 to rise, so that the packaged glass wool panels are moved out of the packaging box 5.

[0037] Working principle of the present invention: The automatic unloading and packaging mechanism of the glass wool board of the present invention is provided with a coating structure 2. The hot air unit 211 of the coating structure 2 can blow the fibers on the surface of the glass wool board during transportation to treat the surface fibers; then the glass wool board moves between the coating boxes 28 on both sides, and the coating liquid inside the coating box 28 soaks the transfer cotton 210, and the transfer cotton 210 transfers the coating liquid to the rotating wheel 25; the rotating wheel 25 smears the surface coating liquid on both sides of the glass wool board when assisting the movement of the glass wool board, and at the same time, the blowing port of the hot air unit 211 blows hot air to the side to accelerate the molding, and the air from the blowing port contacts the wind shield 27 of the rotating shaft 26 to assist the rotating wheel 25 to rotate, thereby blowing off the fibers on the surrounding sides of the glass fiber and then performing the coating operation; by providing the coating box 28 and the sealing plate 29, the hot air unit 211 can be directly disassembled from the surface of the coating box 28, and after the sealing plate 29 is disassembled, it is convenient to clean and replace the internal transfer cotton 210, and it is also convenient to replace and check the coating liquid in the slot of the coating box 28.
