Description

Technical Field

[0001] The utility model relates to the technical field of processing and production of flame-retardant protection plates, and more specifically, to a processing device for composite flame-retardant protection plates. Background Art

[0002] The composite flame-retardant protection plate is a material that can effectively prevent the spread of fire. It has the characteristics of preventing the spread of flames, slowing down the spread of smoke, and reducing the risk of fire outbreak. In its processing and production, there is a step of coating an adhesive on the surface of the substrate of the plywood, and the surface treatment of the plywood substrate is generally carried out by manual coating or equipment processing. Manual coating is time-consuming and laborious, and the labor intensity is also relatively large; the existing glue coating equipment generally combines a conveying mechanism and a glue coating mechanism, and the surface of the substrate is coated sequentially during the conveying process. The substrate is prone to unevenness and warping due to uneven force during the conveying process, resulting in an uneven glue layer on the surface, poor coating effect, and even affecting the quality of subsequent plywood combination. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a processing device for composite flame-retardant and anti-slip plates, which can solve the technical problem that the glue layer on the surface is uneven due to the unevenness of the substrate during the conveying process of the substrate.

[0004] The utility model provides the following technical solutions: A processing device for a composite flame-retardant protection board, including a machine base, a conveying mechanism located on the machine base, a frame, and a glue coating mechanism located on the frame. The frame and the glue coating mechanism are located above the machine base. The conveying mechanism is used to convey the base material from front to back along the conveying direction. The glue coating mechanism includes a glue injection structure, a front fixed pressing roller, and a rear glue coating pressing roller. The glue injection structure is arranged at the middle position in the conveying direction and includes a glue storage part and a glue injection part at the lower part. The glue injection part includes two arc surfaces symmetrically arranged on both sides and a sealing part at both ends. The upper side of the glue injection part has a larger opening and the lower side has a smaller opening and is used for injecting glue. An opening and closing component is arranged at the glue injection part. The opening and closing component includes a control motor, a central rotating shaft, and an opening and closing valve plate. The central rotating shaft is located in the middle of the glue injection part. The middle of the opening and closing valve plate is connected to the central rotating shaft and is symmetrical relative to the central rotating shaft. The linear distance from the center axis of the two arc surfaces to the central axis of the central rotating shaft gradually increases from the middle to the upper and lower sides. The control motor is arranged outside the glue injection part and is used to control the central rotating shaft to drive the opening and closing valve plate to rotate. The opening and closing component has a closed state where the opening and closing valve plate rotates to a horizontal state and cooperates with the middle of the two arc surfaces, and also has a fully open state where it rotates to a vertical state for the adhesive to pass through. The front fixed pressing roller and the rear glue coating pressing roller are respectively located on the front and rear sides of the glue injection structure. The front fixed pressing roller is used to press against the base material. The rear glue coating pressing roller includes a base roller and a glue coating brush layer arranged on the outer side of the base roller. The rear glue coating pressing roller is rotatably installed at the lower end of a rear fixed frame. The rear fixed frame is connected to the frame. A glue coating motor for driving the rear glue coating pressing roller to rotate is arranged on the rear fixed frame. The rear glue coating pressing roller brushes the adhesive applied to the surface of the base material under the action of the glue coating motor.

[0005] Further, a stirring component is arranged in the glue storage part. A stirring motor is installed outside the glue storage part. The stirring component includes a stirring shaft and stirring parts arranged on the stirring shaft. The upper end of the stirring shaft extends out of the glue storage part and is connected to the stirring motor. The top of the glue storage part is sealed and provided with a glue adding port. The top of the glue storage part is rotatably connected to the stirring shaft.

[0006] Further, the conveying mechanism includes a plurality of conveying rollers and a driving mechanism. The conveying rollers include a driving roller and a driven roller connected in transmission. The driving mechanism is used to drive the driving roller to rotate and drive the driven roller to rotate for conveying.

[0007] Further, the front fixed pressing roller is rotatably installed at the lower end of a front fixed frame. The front fixed frame is connected to the frame. A plurality of air jet nozzles are arranged in sequence on the front side of the lower end of the front fixed frame.

[0008] Further, the air jet nozzles are rotatably installed on the front fixed frame through damping rotating shafts.

[0009] Further, a glue scraping plate for scraping off the excess adhesive on the glue coating brush layer is arranged at the lower end of the rear fixed frame.

[0010] Beneficial effects: When the present utility model is used for processing a composite flame-retardant protection board, the base material is placed on the conveying mechanism from the front end in the conveying direction. The base material is conveyed forward under the action of the conveying mechanism, and is conveyed to the middle of the conveying mechanism after passing through the front fixed pressure roller. The control motor of the opening and closing assembly is turned on in advance to make the switch assembly in a fully open state. The adhesive flows to the upper surface of the base material from the lower opening of the glue injection part. The base material continues to be conveyed backward and moves to the rear glue coating pressure roller. Since the rear glue coating pressure roller rotates under the action of the glue coating motor, the glue coating brush layer on its outer side sequentially coats the adhesive on the upper surface of the base material to make it evenly distributed; during the processing interval and when the machine is idle, the control motor is controlled to switch the switch assembly to a closed state to avoid waste caused by continuous flowing of the adhesive; the above-mentioned processing device is provided with a front fixed pressure roller, a glue injection structure, and a rear glue coating pressure roller distributed from front to back. In the early stage of conveying, the front fixed pressure roller plays a role of guiding and limiting, pressing the front half of the base material to prevent it from warping, which is beneficial to ensuring the uniformity of the glue injection process. In the later stage of conveying, the front and rear halves of the base material are respectively limited by the rear glue coating pressure roller and the front fixed pressure roller to keep the base material in a horizontal state and prevent warping or uneven height. While pressing the base material, the rear glue coating pressure roller coats the adhesive on the surface of the base material under the action of the glue coating motor and coats it evenly; in summary, the present utility model splits the glue injection step and the glue coating step and performs them successively, while completing the uniform coating of the adhesive, restricting the height position of the base material during conveying, thereby ensuring the glue coating uniformity and improving the coating effect, and then being beneficial to improving the bonding quality of the composite flame-retardant protection board.

In this embodiment, the stirring parts 132 are composed of spiral strips on the outer ring and connecting stirring rods connecting the spiral strips and the stirring shaft 131.

[0018] As Figure 1 - Figure 2 shown, the glue injection part 123 includes two arc surfaces 125 symmetrically arranged on both sides and sealing parts at both ends. The upper side of the glue injection part 123 has a large opening, and the lower side has a small opening, which is a glue injection port 124 for injecting glue. An opening / closing assembly for controlling the start / stop of glue injection is arranged at the glue injection part 123. The opening / closing assembly includes a control motor, a central rotating shaft 14 and an opening / closing valve plate 15. The central rotating shaft 14 is located in the middle of the arc surface 125 of the glue injection part. The middle of the opening / closing valve plate 15 is fixedly connected to the central rotating shaft 14 and is symmetric with respect to the central rotating shaft 14. The linear distance from the middle of the two arc surfaces 125 to the central axis of the central rotating shaft gradually increases from the middle to the upper and lower sides. The control motor is arranged outside the glue injection part 123 and is used to control the central rotating shaft 14 to drive the opening / closing valve plate 15 to rotate. A sealing ring for sealingly cooperating with the middle position of the arc surface 125 is arranged outside the opening / closing valve plate 15. Under the drive of the control motor, the opening / closing assembly has: a closed state in which the opening / closing valve plate 15 rotates to a horizontal state and seals with the middle position of the two arc surfaces, and a fully open state in which the opening / closing valve plate 15 rotates to a vertical state for the adhesive to pass through.

[0019] The front fixed pressure roller 5 and the rear glue - applying pressure roller 6 are respectively located on the front and rear sides of the glue - injecting structure. The front fixed pressure roller 5 is rotatably installed at the lower end of the front fixed frame 7, and the front fixed frame 7 is connected to the frame 4. On the front side of the lower end of the front fixed frame, a plurality of air - jet nozzles 9 are arranged in sequence.

At the same time, a glue - scraping plate 10 is arranged at the lower end of the rear fixed frame 8. When the rear glue - applying pressure roller 6 rotates, the glue - scraping plate 10 scrapes off the excess adhesive of the glue - applying brush layer 6 to keep the glue - applying effect uniform.

[0021] When the processing device for the composite flame - retardant protection board of the present utility model is used to produce the composite flame - retardant protection board: Place the base material of the flame - retardant board at the front end of the conveying mechanism. The base material is conveyed forward under the action of the conveying rollers 2. After being pressed and limited by the front fixed pressure roller, it continues to be conveyed forward. When it reaches below the glue - injection port 124, the adhesive in the glue - injecting structure flows onto the base material through the glue - injection port 124, and the upper surface of the base material is sequentially injected with glue as the base material moves. When the base material moves to the position of the rear glue - applying pressure roller, on the one hand, it is brushed by the glue - applying brush layer 62 on the surface of the rear glue - applying pressure roller, and its surface is evenly brushed into a glue - bonded layer. On the other hand, the front and rear parts of the base material are respectively pressed by the rear glue - applying pressure roller and the front fixed pressure roller, preventing warping or unevenness and keeping the base material in a horizontal state to ensure that the glue - bonded layer is evenly applied. The structure is ingeniously set, and the glue - injection and glue - applying steps are carried out separately, improving the brushing effect and thus being beneficial to improving the glue - bonding processing quality of the composite flame - retardant protection board.
