Description

Technical Field

[0001] The utility model relates to the field of paper mounting machines, and particularly relates to an automatic glue application mechanism of a paper mounting machine. Background Technique

[0002] A paper mounting machine is a paper product manufacturing machine, mainly used for pasting papers together, or pasting papers on materials such as wooden boards, plastic boards, and cardboard. The paper mounting machine mainly consists of a paper feeding mechanism, a paper mounting mechanism, and a paper pressing mechanism. Among them, the paper feeding mechanism is responsible for feeding the paper into the machine, the paper mounting mechanism is responsible for bonding the paper and the board together, and the paper pressing mechanism is responsible for pressing the bonded paper. The automatic glue application mechanism of the paper mounting machine is a key part of the equipment. It ensures that the paper or the bottom board can be evenly and stably bonded together by precisely controlling the supply and application process of the glue, improving production efficiency and product quality.

[0003] During the use of the existing automatic glue application mechanism of the paper mounting machine, since the automatic glue application mechanism of the paper mounting machine directly sprays the glue on the coating roller, the glue is too concentrated. If the automatic glue application mechanism of the paper mounting machine lacks a glue dispersing roller and uniform glue application, it will cause the phenomenon of uneven glue on the surface of the paper when the coating roller recoats the paper. At the same time, uneven glue application will directly affect the bonding effect between the paper or the bottom board and another layer of material, resulting in problems such as weak bonding, blistering, and glue peeling, affecting the quality and stability of the product, and indirectly affecting the working efficiency of the paper mounting machine.

[0004] Therefore, it is necessary to invent an automatic glue application mechanism of a paper mounting machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic glue application mechanism of a paper mounting machine. Through the spray glue roller, glue melting roller, second coating roller, fixing plate, electric slide rail, electric slider, and glue dispersing brush, the automatic glue application mechanism of the paper mounting machine is equipped with a method of multiple glue dispersion, making the glue application on the paper by the automatic glue application mechanism of the paper mounting machine more uniform, avoiding the influence of uneven glue application on the bonding effect between the paper or the bottom board and another layer of material, reducing the probability of problems such as weak bonding, blistering, and glue peeling, ensuring the quality and stability of the product, and improving the working efficiency of the paper mounting machine. To solve the problem that during the use of the existing automatic glue application mechanism of the paper mounting machine, since the automatic glue application mechanism of the paper mounting machine directly sprays the glue on the coating roller, the glue is too concentrated. If the automatic glue application mechanism of the paper mounting machine lacks a glue dispersing roller and uniform glue application, it will cause the phenomenon of uneven glue on the surface of the paper when the coating roller recoats the paper. At the same time, uneven glue application will directly affect the bonding effect between the paper or the bottom board and another layer of material, resulting in problems such as weak bonding, blistering, and glue peeling, affecting the quality and stability of the product, and indirectly affecting the working efficiency of the paper mounting machine.

[0006] To achieve the above object, the present utility model provides the following technical solution: an automatic glue application mechanism for a paper pasting machine, including a glue application frame, which is the main body for applying glue to paper;

[0007] A first glue application roller is arranged inside the glue application frame and is used to assist in applying glue to paper. A refeeding roller is arranged on one side of the first glue application roller. An adjusting frame is fixedly installed above the glue application frame. A sliding block is movably connected inside the adjusting frame. A second threaded rod penetrates through the top of the adjusting frame. A glue application plate is fixedly installed outside the sliding block, and glue application grooves are formed on the surface of the glue application plate;

[0008] A glue application frame is arranged above the glue application plate and is used to spray glue on the glue application roller. A servo motor is arranged outside the glue application frame. The output end of the servo motor is fixedly installed with a glue spraying roller. A glue melting roller is arranged below the glue spraying roller, and a second glue application roller is movably connected below the glue melting roller;

[0009] A fixing plate is arranged on one side of the glue application frame and is used to secondarily disperse the glue. An electric slide rail is arranged outside the fixing plate, and an electric slide block is movably connected to the outside of the electric slide rail. One end of the electric slide block is fixedly installed with a glue dispersing brush.

[0010] Preferably, a conveying frame is fixedly installed on one side of the glue application frame, and an electric conveyor belt is arranged inside the conveying frame.

[0011] Preferably, a deviation rectifying frame is fixedly installed above the conveying frame. A first threaded rod penetrates through the outside of the deviation rectifying frame, and a deviation rectifying plate is fixedly installed at one end of the first threaded rod.

[0012] Preferably, a glue water tank is fixedly installed above the glue application plate, and a glue water pump is fixedly installed on the top of the glue water tank.

[0013] Preferably, a glue spraying cavity is fixedly installed on the top of the glue application frame, and atomizing nozzles are fixedly installed at the bottom of the glue spraying cavity.

[0014] Preferably, the number of the atomizing nozzles is set to six, and the six atomizing nozzles are evenly distributed on the glue spraying cavity.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are:

[0016] 1. The utility model is provided with a glue spraying roller, a glue melting roller, a second glue coating roller, a fixing plate, an electric slide rail, an electric slider and a glue spreading brush. When using the automatic glue applying mechanism of this paper pasting machine, the glue is not directly sprayed on the second glue coating roller, but on the glue spraying roller. At this time, the glue that is not evenly spread on the glue spraying roller is coated on the glue melting roller as the glue melting roller rotates, and then the second glue coating roller is also coated with glue as the glue melting roller rotates. In this way, the probability of glue accumulation is greatly reduced by applying glue three times. Then, in cooperation with the glue spreading brush on the side, it brushes back and forth on the surface of the second glue coating roller to make the glue more evenly distributed on the second glue coating roller. With such a combined use, the automatic glue applying mechanism of this paper pasting machine has a method of multiple glue spreading, making the glue applied to the paper by the automatic glue applying mechanism of the paper pasting machine more evenly distributed, avoiding the problem that uneven glue coating affects the bonding effect between the paper or the bottom board and another layer of material, reducing the probability of problems such as insecure bonding, blistering, and glue peeling, ensuring the quality and stability of the product, and improving the working efficiency of the paper pasting machine;

[0017] 2. The utility model is provided with a conveying frame, an electric conveyor belt, a deviation rectifying frame, a first threaded rod and a deviation rectifying plate. When the automatic glue applying mechanism of this paper pasting machine is used in combination with the paper pasting machine, the position of the paper also affects the effect after glue application. When the electric conveyor belt conveys the paper, according to the width of the current paper and the position of the glue applying frame, the position of the deviation rectifying plate on both sides of the electric conveyor belt can be adjusted through the first threaded rod, so as to limit and rectify the deviation of the paper during the conveying process, and make the paper be conveyed into the automatic glue applying mechanism of the paper pasting machine within a fixed range, thereby assisting the glue applying mechanism to complete the glue application work on the paper. In this way, not only the overall glue application efficiency is improved, but also the probability of uneven glue application caused by paper misalignment is reduced.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0027] The present utility model provides an automatic glue application mechanism for a paper mounting machine as shown in Figures 1-5 which includes a glue application frame 1, which is the main body for applying glue to paper;

[0028] The first glue application roller 7 is arranged inside the glue application frame 1 and is used to assist in applying glue to the paper. A re-feeding roller 8 is arranged on one side of the first glue application roller 7. An adjusting frame 9 is fixedly installed above the glue application frame 1. A sliding block 10 is movably connected inside the adjusting frame 9. A second threaded rod 11 passes through the top of the adjusting frame 9. A glue application plate 12 is fixedly installed outside the sliding block 10, and a glue application groove 13 is formed on the surface of the glue application plate 12;

[0029] The glue application rack 16 is arranged above the glue application plate 12 and is used to spray glue on the glue application roller. A servo motor 19 is arranged outside the glue application rack 16. The output end of the servo motor 19 is fixedly installed with a glue spraying roller 20. A glue melting roller 21 is arranged below the glue spraying roller 20. A second glue application roller 22 is movably connected below the glue melting roller 21;

[0030] The fixed plate 23 is arranged on one side of the glue application rack 16 and is used for secondary dispersion of glue. An electric slide rail 24 is arranged outside the fixed plate 23, and an electric slider 25 is movably connected to the outside of the electric slide rail 24. One end of the electric slider 25 is fixedly installed with a glue dispersion brush 26. The glue is not directly sprayed on the second glue application roller 22, but on the spray glue roller 20. At this time, the glue that is not evenly dispersed is applied to the melting glue roller 21 as the melting glue roller 21 rotates, and then the second glue application roller 22 is also coated with glue as the melting glue roller 21 rotates. In this way, the probability of glue accumulation is greatly reduced by applying glue three times. Coupled with the side glue dispersion brush 26, it brushes back and forth on the surface of the second glue application roller 22 to make the glue more uniform on the second glue application roller 22.

[0031] As Figure 1 , Figure 2 and Figure 3 shown, a conveying rack 2 is fixedly installed on one side of the glue application machine rack 1. An electric conveyor belt 3 is arranged inside the conveying rack 2. The conveying rack 2 and the electric conveyor belt 3 together with the glue application machine rack 1 form an automatic glue application mechanism, which is convenient for matching with the paper pasting machine to improve work efficiency. A deviation rectifying rack 4 is fixedly installed above the conveying rack 2. A first threaded rod 5 passes through the outside of the deviation rectifying rack 4. One end of the first threaded rod 5 is fixedly installed with a deviation rectifying plate 6. When the electric conveyor belt 3 conveys the paper, according to the width of the current paper and the position of the glue application machine rack 1, the position of the deviation rectifying plate 6 on both sides of the electric conveyor belt 3 can be adjusted through the first threaded rod 5, so as to limit and rectify the deviation of the paper during the conveying process, and make the paper be conveyed into the automatic glue application mechanism of the paper pasting machine within a fixed range. A glue tank 14 is fixedly installed above the glue application plate 12. A glue water pump 15 is fixedly installed on the top of the glue tank 14. The glue is pumped out of the glue tank 14 through the glue water pump 15, rather than being directly exposed outside, which slows down the volatilization speed of the glue viscosity and helps the subsequent glue application work to be carried out better.

[0032] As Figure 1 , Figure 4 and Figure 5 shown, a spray glue cavity 17 is fixedly installed on the top of the glue application rack 16. An atomizing nozzle 18 is fixedly installed at the bottom of the spray glue cavity 17. Multiple groups of atomizing nozzles 18 can spray glue on the spray glue roller 20 evenly, reducing the probability of large pieces of glue accumulating together and reducing the pressure on the subsequent glue dispersion step. The number of atomizing nozzles 18 is set to six, and the six atomizing nozzles 18 are evenly distributed on the spray glue cavity 17. The structure of the atomizing nozzle 18 is simple and easy to operate. If a failure occurs, it is also convenient for maintenance personnel to replace and repair it in time without delaying the normal use of the device.

[0033] The working principle of this utility model: First, the automatic glue application mechanism of this paper pasting machine is used in combination with the paper pasting machine. The conveying rack 2 and the electric conveyor belt 3 can convey the paper. Then, the position of the paper also affects the effect after glue application. When the electric conveyor belt 3 conveys the paper, according to the width of the current paper and the position of the glue application rack 1, the deviation correction plate 6 is adjusted on both sides of the electric conveyor belt 3 through the first threaded rod 5, so as to limit and correct the deviation of the paper during the conveying process, and let the paper be conveyed into the automatic glue application mechanism of the paper pasting machine within a fixed range. Then, according to the thickness of the paper, turn the second threaded rod 11 on the adjusting frame 9 to adjust the position of the sliding block 10 on the adjusting frame 9, so that the glue application plate 12 connected to the sliding block 10 is closer to the second glue application roller 22 and the first glue application roller 7. Then, turn on the switch of the servo motor 19, and let the servo motor 19 drive the glue spraying roller 20 and the glue melting roller 21 to rotate through the turntable. Subsequently, turn on the switch of the glue water pump 15, and the glue water is pumped out of the glue water tank 14 by the glue water pump 15, rather than being directly exposed outside, which slows down the volatilization speed of the glue viscosity. The glue water is conveyed into the glue spraying cavity 17 and then sprayed out from the atomizing nozzles 18. Multiple groups of atomizing nozzles 18 can spray glue on the glue spraying roller 20 evenly, reducing the probability of large pieces of glue accumulating together and reducing the pressure on the subsequent glue spreading step. In this way, when applying glue, the glue is not directly sprayed on the second glue application roller 22, but on the glue spraying roller 20. At this time, the glue that has not been evenly spread is applied to the glue melting roller 21 as the glue melting roller 21 rotates, and then the second glue application roller 22 is also coated with glue as the glue melting roller 21 rotates. In this way, three times of glue application greatly reduces the probability of glue accumulation. Then, turn on the switch of the electric slide rail 24, and let the electric slide rail 24 and the electric slider 25 drive the side glue spreading brush 26 to brush back and forth on the surface of the second glue application roller 22, making the glue more evenly distributed on the second glue application roller 22. Subsequently, as the paper passes through, under the repeated coating of the second glue application roller 22 and the first glue application roller 7, the glue application work on the paper is completed. In this way, the automatic glue application mechanism of this paper pasting machine has a method of multiple glue spreading, making the glue application of the automatic glue application mechanism of the paper pasting machine more even on the paper, avoiding the influence of uneven glue application on the bonding effect between the paper or the bottom plate and another layer of material. The glued paper is driven by the refeeding roller 8 and enters the next production process of the paper pasting machine. Finally, after completing all the installation and use work of the automatic glue application mechanism of the paper pasting machine according to the above operations, turn off the switch of the electric conveyor belt 3, turn off the switch of the glue water pump 15, turn off the switch of the servo motor 19, turn off the switch of the electric slide rail 24. If it is not used for a long time, cut off the external power supply. Just like this, the use process of the automatic glue application mechanism of this paper pasting machine is completed.

[0034] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
