Description

Technical Field

[0001] This utility model relates to the field of wood board gluing technology, and in particular to a wood flooring production gluing device. Background Technology

[0002] There are many types of wood flooring, and composite wood flooring is one of the most advantageous. It not only has a low rate of shrinkage and expansion due to dryness and moisture, and excellent dimensional stability, but also perfectly retains the natural wood grain texture and comfortable feel of solid wood flooring. This type of flooring is made by bonding and pressing multiple layers of boards together. During the production process, an adhesive applicator is used to evenly apply adhesive to the surface of each layer of substrate to ensure the bonding strength between the boards and the quality of the finished product.

[0003] A multi-sided adhesive applicator disclosed in Chinese Patent Publication No. CN223573392U uses a rotating brush to clean the surface of the board and a dust collection mechanism to collect the dust, effectively avoiding the impact of dust on the adhesive application. However, according to existing multi-sided adhesive applicators and technologies in related fields, traditional applicators require the glue to be added to a temporary storage space between the applicator roller and the auxiliary roller during operation. The coating operation is completed using the glue stored in this area. However, the volume of this temporary storage space is limited. In continuous adhesive production, frequent machine stops are required to replenish the glue, which not only interrupts the production cycle and reduces the overall processing speed, but also easily causes fluctuations in the amount of glue applied due to frequent start-stop operations, affecting the uniformity of the wood flooring adhesive application. At the same time, after the equipment stops, glue residue remains in the temporary storage space, resulting in waste and increasing production costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a wood flooring production glue application device.

[0005] The purpose of this utility model is achieved through the following technical solution: a wood flooring production glue application device, including a glue application machine body, in which a glue application roller and an auxiliary roller for rotating glue application are symmetrically installed inside the glue application machine body. Multiple conveying rollers for conveying wood boards are installed below the glue application roller in the glue application machine body. Two baffle plates for blocking glue from both ends are symmetrically arranged between the glue application roller and the auxiliary roller. A glue storage tank is fixedly installed above the glue application roller in the glue application machine body. A glue dispensing component for controlling glue discharge is provided at the bottom of the glue storage tank. A suction component for extracting and pressing out glue is provided at the top of the glue storage tank. Synchronization components for controlling the opening and closing of the glue dispensing component with the suction and pressing action are provided on both sides of the suction component. The dispensing assembly includes a dispensing hopper fixed to the bottom of the glue storage tank. The bottom of the dispensing hopper is conical and has two valve plates symmetrically arranged.

[0006] Preferably, both valve plates are inclined toward each other, and triangular plates are fixedly provided at both ends of the dispensing hopper corresponding to the two valve plates.

[0007] Preferably, the suction assembly includes an air cylinder embedded and fixed to the top of the glue storage tank, a piston is slidably installed inside the air cylinder, a control rod is fixedly provided on the top of the piston, the control rod extends upward through the air cylinder, a lifting plate is fixedly provided on the top of the control rod, and a handle is fixedly provided on the top of the lifting plate.

[0008] Preferably, the synchronization component includes a synchronization frame fixed on the lifting plate, and the synchronization frame is provided with a horizontal rail corresponding to the position of each valve plate. A sliding pin is slidably installed inside each horizontal rail, and the end of the sliding pin is fixed to the top of the corresponding valve plate.

[0009] Preferably, the side wall of the air cylinder is provided with a plurality of air holes that communicate with the glue storage tank, the air holes are located above the piston, and the bottom of the air cylinder is fixedly provided with an air inlet pipe that communicates with the outside of the glue storage tank.

[0010] Preferably, the glue dispensing hopper has a movable groove corresponding to the position of each valve plate, and both valve plates are slidably installed inside the corresponding movable groove.

[0011] Preferably, the glue storage tank is fixedly provided with a sliding sleeve corresponding to the position of each of the synchronization frames.

[0012] Preferably, the top of the glue storage tank is fixedly provided with a feed pipe, and the top of the feed pipe is fixedly installed with a sealing cap.

[0013] The beneficial effects of this wood flooring glue application device are as follows: By setting up a glue dispensing component, a suction component, and a synchronization component, and utilizing the principles of liquid seal and liquid level difference, the glue is automatically replenished when the glue level in the temporary glue storage space drops, completing the glue replenishment process without manual intervention. This eliminates the need for frequent glue replenishment, improving the continuity and stability of production and ensuring the uniformity of glue application. When production stops, the downward movement of the lifting plate generates a negative pressure suction effect, while the linkage valve plate closes the glue outlet downwards. This achieves integrated glue recovery and outlet closure. Furthermore, during the valve plate closure process, in conjunction with the triangular plate, the height of the glue outlet can be gradually lowered and brought deeper into the temporary glue storage space. This design, in conjunction with the suction action, enhances the thoroughness of glue recovery and reduces the amount of glue remaining in the temporary glue storage space.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0019] like Figures 1 to 7 As shown, a wood flooring production glue application device includes a glue application machine body 1. Inside the glue application machine body 1, a glue application roller 2 and an auxiliary roller 3 are symmetrically installed for rotating and applying glue. Two baffle plates 10 are symmetrically arranged between the glue application roller 2 and the auxiliary roller 3 to block the glue from both ends. A glue storage tank 4 is fixedly installed above the glue application roller 2 on the glue application machine body 1. A glue dispensing component 5 for controlling glue discharge is located at the bottom of the glue storage tank 4. A suction component 6 for extracting and dispensing glue is located at the top of the glue storage tank 4. Synchronization components 7 are provided on both sides of the suction component 6 to control the opening and closing of the glue dispensing component 5 during suction and pressure actions. The main body 1 of the glue applicator is located below the glue applicator roller 2 and is equipped with multiple conveyor rollers 13 for conveying wooden boards. A feed pipe 9 is fixedly installed on the top of the glue storage tank 4, and a sealing cap 8 is fixedly installed on the top of the feed pipe 9. Initially, the glue applicator roller 2 and auxiliary roller 3, together with two glue baffles 10, form a temporary glue storage space. The glue dispensing assembly 5 is in the closed state. Before use, the sealing cap 8 is opened, and glue is added into the glue storage tank 4 through the feed pipe 9. After adding the glue, the sealing cap 8 is closed again, and the glue dispensing assembly 5 is opened, allowing the glue to flow through the glue dispensing assembly 5 into the temporary glue storage space. When the glue dispensing space is filled with glue... When the glue level is higher than the outlet of the glue dispensing assembly 5, the outlet is closed, preventing air from entering the glue storage tank 4. The air pressure inside and outside the glue storage tank 4 is balanced, and the glue cannot continue to be discharged. During operation, the wood board passes under the glue application roller 2 and the auxiliary roller 3, and is conveyed to the other side supported by multiple conveying rollers 13. During this process, the glue application roller 2 and the auxiliary roller 3 rotate inward relative to each other, continuously coating the surface of the wood board with the glue from the temporary glue storage space, causing the glue level inside the temporary glue storage space to decrease. At this point, the outlet of the glue dispensing assembly 5 is reopened, automatically replenishing the glue until the glue level is higher than the outlet of the glue dispensing assembly 5. The above process utilizes the principles of liquid seal and liquid level difference. When the glue in the storage space decreases to the point where the liquid level is lower than the glue outlet, the glue in the storage tank 4 can automatically flow out to replenish it without manual intervention, thus automating the glue replenishment process. When work stops, the suction component 6 is controlled to perform a suction action, generating negative pressure inside the storage tank 4 to suck up the glue in the temporary storage space and recover the residual glue. At the same time, the suction component 6 controls the glue outlet component 5 to automatically close through the synchronization component 7, stopping the glue dispensing. The suction of the glue and the closing of the glue outlet are controlled in an integrated manner, simplifying the operation process.

[0020] like Figure 2 , Figure 5 and Figure 7As shown, the glue dispensing assembly 5 includes a glue dispensing hopper 51 fixed to the bottom of the glue storage tank 4. The bottom of the glue dispensing hopper 51 is conical and symmetrically provided with two valve plates 52. Both valve plates 52 are inclined towards each other. Triangular plates 53 are fixed at both ends of the glue dispensing hopper 51 corresponding to the two valve plates 52. The glue dispensing hopper 51 has a movable groove 11 corresponding to the position of each valve plate 52. Both valve plates 52 are slidably installed inside the corresponding movable groove 11. The bottom of the glue dispensing hopper 51 extends into the temporary glue storage space between the glue coating roller 2 and the auxiliary roller 3. Through the principle of liquid seal and liquid level difference, when the glue is stored... When the amount of adhesive inside the space decreases to the point where the liquid level is below the bottom of the dispensing hopper 51, the adhesive inside the storage tank 4 can be automatically replenished by flowing out through the dispensing hopper 51 without manual intervention, thus automating the adhesive replenishment process. When the two inclined valve plates 52 move up and down along the movable groove 11, they cooperate with the triangular plates 53 at both ends to gradually change the outlet height of the dispensing hopper 51. At the same time, the bottoms of the two valve plates 52 gradually move closer or further apart. When the bottoms of the two valve plates move further apart, the outlet of the dispensing hopper 51 is opened. When the bottoms of the two valve plates are in complete contact, the outlet of the dispensing hopper 51 is completely closed.

[0021] For example Figure 2 , Figure 4 and Figure 6 As shown, the suction assembly 6 includes an air cylinder 61 embedded and fixed to the top of the glue storage tank 4. A piston 62 is slidably installed inside the air cylinder 61. A control rod 63 is fixedly mounted on the top of the piston 62, extending upward through the air cylinder 61. A lifting plate 64 is fixedly mounted on the top of the control rod 63, and a handle 65 is fixedly mounted on the top of the lifting plate 64. Multiple air holes 66 communicating with the glue storage tank 4 are evenly distributed on the side wall of the air cylinder 61. The air holes 66 are located above the piston 62. An air inlet pipe 67 communicating with the outside of the glue storage tank 4 is fixedly mounted on the bottom of the air cylinder 61. When extracting residual glue, the lifting plate 64 and the control rod 63 are pushed downward by the handle 65 to control the flow of the glue. Rod 63 drives piston 62 to move downwards inside air cylinder 61, drawing air from the upper chamber of air cylinder 61 to create negative pressure inside glue storage tank 4, thereby absorbing residual glue through glue dispensing hopper 51. The lower chamber of air cylinder 61 is connected to the outside of glue storage tank 4 through air inlet pipe 67, ensuring air pressure balance between the upper and lower chambers of air cylinder 61 during suction. When lifting plate 64 moves upwards, it drives piston 62 upwards through control rod 63, inflating the inside of glue storage tank 4 to create positive pressure, thereby quickly discharging glue. Combined with the flat glue dispensing hopper 51, glue quickly fills the temporary glue storage space, accelerating the glue dispensing speed at startup.

[0022] like Figures 2 to 7As shown, the synchronization assembly 7 includes a synchronization frame 71 fixed on the lifting plate 64. A horizontal rail 72 is fixedly provided on the synchronization frame 71 corresponding to the position of each valve plate 52. A sliding pin 73 is slidably installed inside each horizontal rail 72, and the end of each sliding pin 73 is fixed to the top of the corresponding valve plate 52. A sliding sleeve 12 is fixedly provided on the glue storage tank 4 corresponding to the position of each synchronization frame 71 to restrict the movement direction of the synchronization frame 71. When the lifting plate 64 moves downward, it will perform a suction action. At the same time, the lifting plate 64 drives the horizontal rail 72 and its internal sliding pin 73 downward through the synchronization frame 71, causing the sliding pin 73 to drive the valve plate 52 downward, gradually closing the glue outlet. The sliding pin 73 is slidably connected to the horizontal rail 72, without restricting the movement of the valve plate 52. The lateral displacement of pin 73 ensures that valve plate 52 can smoothly tilt downwards. During this process, valve plate 52 cooperates with triangular plate 53 to gradually reduce the height of the glue outlet, allowing the glue outlet to penetrate into the temporary glue storage space, thus improving the thoroughness of glue recovery. Finally, the bottoms of the two valve plates 52 contact each other, sealing the glue storage port and stopping glue dispensing. When lifting plate 64 moves upwards, it will perform glue dispensing. At the same time, lifting plate 64 drives horizontal rail 72 and its internal sliding pin 73 to move upwards through synchronous frame 71, causing sliding pin 73 to drive valve plate 52 to gradually open the glue outlet, thereby quickly discharging glue. Through the above process, the glue dispensing and suction are integrated with the opening and closing of the glue outlet, simplifying the operation process.

[0023] The work process is as follows: S1: As Figure 2 As shown, before use, open the sealing cover 8 and add adhesive into the glue storage tank 4 through the feed pipe 9. After adding, close the sealing cover 8 again. S2: As Figures 2 to 5 As shown, the lifting plate 64 and control lever 63 are pushed upward by the handle 65. The control lever 63 drives the piston 62 to move upward, inflating the inside of the glue storage tank 4 and creating positive pressure inside. At the same time, the lifting plate 64 drives the horizontal rail 72 and its internal sliding pin 73 to move upward through the synchronous frame 71. The sliding pin 73 drives the valve plate 52 to open the glue outlet, thereby quickly discharging the glue. With the help of the flat glue hopper 51, the glue is evenly distributed in the temporary glue storage space. S3: As Figure 2 and Figure 4 As shown, when the liquid level of the adhesive inside the temporary storage space is higher than the outlet of the dispensing hopper 51, the outlet is sealed, and air cannot enter the interior of the storage tank 4. The air pressure inside and outside the storage tank 4 is balanced, and the adhesive cannot continue to be discharged. S4: As Figure 1 and Figure 4As shown, during operation, the wood board passes under the glue roller 2 and the auxiliary roller 3, and is conveyed to the other side by the support of multiple conveying rollers 13. During this process, the glue roller 2 and the auxiliary roller 3 rotate inward relative to each other, continuously coating the glue in the temporary glue storage space onto the surface of the wood board. S5: As Figure 2 and Figure 4 As shown, during the glue application process, the glue level inside the temporary glue storage space decreases. At this time, the outlet of the glue dispensing hopper 51 is reopened, and glue is automatically replenished until the glue level is higher than the outlet of the glue dispensing hopper 51. This process utilizes the principle of liquid seal and liquid level difference. When the glue level inside the glue storage space decreases to the point where it is lower than the glue outlet, the glue level inside the glue storage tank 4 can automatically flow out to replenish the glue without manual intervention, thus automating the glue replenishment process. S6: As Figures 4 to 7 As shown, when work stops, the lifting plate 64 is controlled to move downward to perform a suction action, generating negative pressure inside the glue storage tank 4. At the same time, the lifting plate 64 drives the horizontal rail 72 and its internal sliding pin 73 to move downward through the synchronous frame 71, causing the sliding pin 73 to drive the valve plate 52 to move downward and gradually close the glue outlet. S7: As Figures 4 to 7 As shown, during the closing process of the glue outlet, the valve plate 52 and the triangular plate 53 cooperate to gradually lower the height of the glue outlet, allowing the glue outlet to penetrate into the temporary glue storage space. This design, in conjunction with the suction action, can improve the thoroughness of glue recovery. Finally, the bottoms of the two valve plates 52 come into contact with each other, sealing the glue storage port and stopping the glue dispensing.
