Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, specifically to an automatic double-sided adhesive coating and drying tunnel device. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneers glued perpendicular to each other. After the double-sided gluing machine applies glue to both sides of the board, the boards need to be bonded together, and then a drying device is used to dry them so that the boards can be quickly bonded together. In the existing technology, after the boards enter the drying device, the overall heating of the boards is not uniform enough, resulting in an unsatisfactory drying effect.

[0003] For example, patent publication number CN219415488U describes a plywood drying device, including a box body with an insulation structure on the outer wall, a mesh plate inside the horizontal plate, a support frame fixed to one side of the top of the horizontal plate, a protective pad fixed to the top of the support frame, a moisture-proof structure at the bottom of the box body, and a door at one end of the box body. This invention improves the space utilization of the box body by using auxiliary structures and fixing the horizontal plates at equal intervals to both sides of the connecting rod. The symmetrically fixed support frames at the top of the horizontal plates create a gap between the plywood and the horizontal plate when it is placed on top. The protective pads fixed to the top of the support frames protect the plywood from friction. The mesh plate inside the horizontal plate allows the bottom of the suspended plywood to be dried, thus improving the drying efficiency and shortening the drying time. However, there is a problem that the plywood is not heated evenly after entering the drying device, resulting in an unsatisfactory drying effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic double-sided adhesive coating drying tunnel device, which solves the problem that the overall heating of the board is not uniform after it enters the drying device, resulting in an unsatisfactory drying effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic double-sided adhesive coating drying tunnel device, including a conveyor belt, a rotary drying mechanism on the conveyor belt, a support at the bottom of the rotary drying mechanism, and a waste gas treatment mechanism on the rotary drying mechanism;

[0006] The rotary drying mechanism includes an arc-shaped drying tunnel and multiple fixed seats. A drying chamber is formed inside the arc-shaped drying tunnel.

An internal threaded sleeve is fixedly connected to the support plate. A clamping screw is threaded inside the internal threaded sleeve. A movable clamping plate is rotatably connected to the end of the clamping screw.

[0007] Preferably, the support is located at the bottom of the arc-shaped drying tunnel, and the arc-shaped drying tunnel is located at the top of the conveyor belt, so that the boards on the conveyor belt can enter and exit the arc-shaped drying tunnel and be fully dried using the arc-shaped drying tunnel.

[0008] Preferably, the conveyor belt has multiple connecting holes, and the fixing seat is fixedly installed on the conveyor belt through fixing holes, bolts and nuts and connecting holes, so that the fixing seat can be fixed on the conveyor belt.

[0009] Preferably, the arc-shaped toothed rail is matched with the driven gear, and the arc-shaped toothed rail is detachably connected to the inner wall of the arc-shaped drying tunnel, making it easy to replace the arc-shaped toothed rail.

[0010] Preferably, protective pads are fixedly connected to the opposite surfaces of the movable clamping plate and the fixed clamping plate, and the bottom end of the movable clamping plate is slidably connected to the guide rail, so as to guide the movement of the movable clamping plate.

[0011] Preferably, one end of the clamping screw has an insertion hole, and the other end of the clamping screw is rotatably connected to the movable clamping plate through a bearing, so that the clamping screw can push the movable clamping plate to move when it rotates.

[0012] Preferably, the waste gas treatment mechanism includes a filter box, one end of which is fixedly connected to an exhaust fan, and the end of the exhaust fan is connected to an air pipe.

The infrared heater radiates heat to the board, and the rotating seat rotates during the movement, which drives the board to rotate, so that the board can be heated evenly and effectively improve the drying effect.

[0015] 2. This automatic double-sided adhesive coating drying tunnel device uses an exhaust fan to extract the gas generated inside the arc-shaped drying tunnel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3This utility model provides a technical solution: an automatic double-sided adhesive coating drying tunnel device, including a conveyor belt 1, a rotary drying mechanism 2 on the conveyor belt 1, a support 3 at the bottom of the rotary drying mechanism 2, and a waste gas treatment mechanism 4 on the rotary drying mechanism 2. The conveyor belt 1 can transport the board, and the rotary drying mechanism 2 makes the board rotate during the drying process, so that the board can be heated evenly and effectively improve the drying effect.

[0023] The rotary drying mechanism 2 includes an arc-shaped drying tunnel 201 and multiple fixed seats 202. A support 3 is located at the bottom of the arc-shaped drying tunnel 201, which is positioned at the top of the conveyor belt 1, allowing the sheet material on the conveyor belt 1 to enter and exit the arc-shaped drying tunnel 201. The arc-shaped drying tunnel 201 is used to thoroughly dry the sheet material. A drying chamber 203 is formed inside the arc-shaped drying tunnel 201. Multiple infrared heaters 204 and arc-shaped toothed rails 205 are fixedly installed on the inner wall of the arc-shaped drying tunnel 201. The infrared heaters 204 utilize electromagnetic radiation to transfer energy, inducing molecular resonance through wavelength matching. Heat is applied to reach the drying temperature. Each fixed seat 202 has multiple fixing holes 214, and the conveyor belt 1 has multiple connecting holes. The fixed seat 202 is fixedly installed on the conveyor belt 1 through the fixing holes 214, bolts and nuts, and connecting holes, so that the fixed seat 202 can be fixed on the conveyor belt 1 and can be replaced. The top of the fixed seat 202 is rotatably connected to the rotating seat 206 through a damping shaft, so that the fixed seat 202 can remain stable during movement. The outer surface of the rotating seat 206 is fixedly connected to the driven gear 207 and the arc-shaped gear rail. 205 is matched with the driven gear 207. The arc-shaped gear 205 is detachably connected to the inner wall of the arc-shaped drying tunnel 201, making it easy to replace the arc-shaped gear 205. A guide slide rail 208 is fixedly connected to the top of the rotating seat 206. A fixing clamping plate 209 and a support plate 210 are fixedly connected to both ends of the guide slide rail 208, respectively. An internal threaded sleeve 211 is fixedly connected to the support plate 210. A clamping screw 212 is threadedly connected inside the internal threaded sleeve 211, so that when the clamping screw 212 rotates, it can move axially along the internal threaded sleeve 211. One end has an insertion hole, into which tools such as pry rollers can be inserted to facilitate the rotation of the clamping screw 212. The other end of the clamping screw 212 is rotatably connected to the movable clamping plate 213 via a bearing, so that the clamping screw 212 can push the movable clamping plate 213 to move when it rotates. The movable clamping plate 213 is rotatably connected to the end of the clamping screw 212. Protective pads are fixedly connected to the opposite surfaces of the movable clamping plate 213 and the fixed clamping plate 209. The bottom end of the movable clamping plate 213 is slidably connected to the guide rail 208, so that the movement of the movable clamping plate 213 can be guided.

[0024] Please see Figure 1 and Figure 4The exhaust gas treatment mechanism 4 includes a filter box 401. One end of the filter box 401 is fixedly connected to an exhaust fan 402, and the end of the exhaust fan 402 is connected to an air pipe 403. One end of the air pipe 403 is connected to the arc-shaped drying tunnel 201. Multiple slots are provided on the top surface of the filter box 401, and activated carbon filter elements 404 are inserted into the multiple slots. The exhaust fan 402 can draw out the gas generated inside the arc-shaped drying tunnel 201 and the gas enters the filter box 401. The gas is filtered by the multiple activated carbon filter elements 404 inside the filter box 401 and then discharged from the outlet end, so that the exhaust gas generated during drying can be centrally treated to avoid polluting the surrounding environment.

[0025] During operation, the double-sided gluing machine applies glue to both sides of the boards, bonding multiple boards together. The bonded boards are then placed on the rotating seat 206, and a tool is inserted into the clamping screw 212. The clamping screw 212 rotates and moves axially along the internal threaded sleeve 211. The movement of the clamping screw 212 pushes the movable clamping plate 213 to move along the guide rail 208. The movable clamping plate 213 cooperates with the fixed clamping plate 209 to clamp the boards. Then, the conveyor belt 1 sends the boards into the arc-shaped drying tunnel 201. The infrared heater 204 radiates heat to the boards. Once the boards enter the arc-shaped drying tunnel 201, the driven gear 207 meshes with the arc-shaped toothed rail 205, causing the driven gear 207 to roll along the arc-shaped toothed rail 205. The rotation of the driven gear 207 drives the rotating seat 206 to rotate, which in turn drives the boards to rotate, ensuring that the boards are heated evenly and effectively improving the drying effect.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
