Description

Technical Field

[0001] The utility model belongs to the technical field of plywood processing devices, in particular to a high-efficiency gluing device for plywood. Background Art

[0002] With the rapid development of modern furniture manufacturing and construction industries, the demand for plywood, a widely used basic material, is indeed growing. The quality of plywood not only directly affects the appearance, performance and service life of the final product, but also affects consumer satisfaction and the market competitiveness of the company. Therefore, as a key link in the plywood production process, quality control of gluing is particularly important. Traditional gluing methods often have the following significant problems:

[0003] 1. Uneven glue application:

[0004] Traditional methods may rely on manual operation or simple mechanical equipment, making it difficult to precisely control the amount of glue applied. Uneven glue application can directly affect the bonding strength and overall quality of the plywood, resulting in excessive glue waste in some areas and insufficient glue in others, leading to weak adhesion.

[0005] 2. Glue precipitation and stratification:

[0006] Glue that has been left standing for a long time is prone to sedimentation and stratification, with the upper layer becoming thinner and the lower layer becoming thicker. Sedimented and stratified glue will cause inconsistent adhesion during coating, affecting the uniformity and stability of the plywood.

[0007] 3. Low drying efficiency:

[0008] Traditional drying methods may use natural air drying, which results in a slow and uneven drying process. Inefficient drying will extend the production cycle, increase production costs, and may affect the final performance of the plywood. Especially in an environment with high humidity, the effect of natural air drying is even worse, and it may even cause the glue to mold during the drying process. Utility Model Content

[0009] The utility model provides a high-efficiency gluing device for plywood, aiming to solve the problems of uneven gluing, glue precipitation and stratification, and low drying efficiency in traditional gluing methods.

[0010] The utility model is implemented as follows: a high-efficiency glue coating device for plywood, comprising a support base; a conveyor belt arranged at the middle position of the upper surface of the support base; a coating brush assembly and a drying assembly are sequentially arranged on the support base according to the processing sequence; wherein the coating brush assembly comprises: a first processing chamber arranged on the support base; an extension bracket arranged at the outside of the processing chamber; a glue storage cylinder arranged at the outside of the extension bracket, the glue storage cylinder being filled with glue; a stirring shaft rotating in the glue storage cylinder, a plurality of stirring blades being arranged at the outside of the stirring shaft; a glue coating pipe is connected to the bottom position of the glue storage cylinder, the glue coating pipe extends to the upper position of the support base and is connected to a plurality of lower glue ports; a one-way valve is provided on the glue coating pipe; a group of electric push rods symmetrically arranged at the top position of the first processing chamber; the telescopic ends of the two electric push rods extend to the inner position of the first processing chamber and are provided with the same assembly seat; a roller shaft rotating in the assembly seat, a roller brush is sleeved on the roller shaft.

[0011] Preferably, the brush assembly also includes: a first motor arranged at the top position of the glue storage cylinder, the output end of the first motor is fixedly connected to the end key of the stirring shaft; a second motor arranged on the outer side wall of the assembly seat, the output end of the second motor is fixedly connected to the end key of the roller shaft.

[0012] Preferably, the drying component includes: a second processing chamber arranged on the support seat; a heating wire arranged on the inner side wall of the second processing chamber, and the heating wire is distributed in a ring shape; and a group of circulation fans symmetrically arranged at the top position of the inner cavity of the second processing chamber.

[0013] Preferably, the drying component further comprises: a fan arranged on the outer side wall of the second processing chamber, one end of the fan is connected to the second processing chamber, and the other end of the fan is connected to an air guide port.

[0014] Preferably, an active adsorption filter layer is provided in the air guide port.

[0015] Preferably, the inner walls of the glue storage cylinder and the second processing chamber are both provided with temperature sensors.

[0016] Preferably, the first processing chamber and the second processing chamber are both box structures with open ends, wherein shielding curtains are provided at both sides of the openings of the second processing chamber.

[0017] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0018] First, a rotatable stirring shaft is installed in the glue storage barrel to ensure the uniformity and fluidity of the glue during storage. The continuous rotation of the stirring shaft quickly and evenly stirs the glue in the glue storage barrel through the stirring blades, effectively preventing the glue from settling or stratifying due to long-term static state, thereby significantly improving the gluing effect. At the same time, the device is also equipped with a liftable roller brush. When the glued plywood enters the first processing chamber, the roller brush can accurately contact and cover the surface of the plywood, evenly applying the glue to the plywood, ensuring the uniformity and consistency of the glue. This precise gluing method not only improves production efficiency, but also guarantees the final quality of the product.

[0019] Secondly, the device heats the air to the set temperature through a heating wire and uses the wind force generated by the circulating fan to evenly blow the hot air to every corner of the processing chamber, achieving all-round, no-dead-angle heating of the plywood surface. This efficient hot air circulation not only accelerates the evaporation process of the solvent or water inside the glue, but also ensures the consistency and uniformity of the glue drying. In addition, in exhaust mode, the fan can promptly extract the hot and humid air from the processing chamber and release it into the external environment through the air duct. At the same time, the active adsorption filter layer set in the air duct can absorb and remove moisture and other harmful substances in the air, ensuring that the exhausted moisture is discharged in a timely manner after being properly treated, reducing pollution to the environment.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The embodiment of the utility model provides a high-efficiency glue coating device for plywood, such as Figure 1-4 As shown, it includes a support base 1; a feed belt 2 provided at the middle position of the upper surface of the support base 1; a brushing assembly and a drying assembly are arranged on the support base 1 in sequence according to the processing order; wherein the brushing assembly includes: a first processing chamber 3 provided on the support base 1; an extension bracket 4 provided on the outside of the processing chamber; a glue storage cylinder 5 provided on the outside of the extension bracket 4, the glue storage cylinder 5 is filled with glue; a stirring shaft 6 rotating in the glue storage cylinder 5, and a plurality of stirring blades 7 are provided on the outside of the stirring shaft 6; the bottom position of the glue storage cylinder 5 is connected to a glue pipe 22, and the glue pipe 22 extends to the upper position of the support base 1 and is connected to a plurality of lower glue ports 23; a one-way valve 24 is provided on the glue pipe 22; a group of electric push rods 8 symmetrically provided at the top position of the first processing chamber 3; the telescopic ends of the two electric push rods 8 extend to the internal position of the first processing chamber 3 and are provided with the same assembly seat 9; a roller shaft 10 rotating in the assembly seat 9, and a roller brush 11 is sleeved on the roller shaft 10.

[0028] It should be noted that, since traditional gluing methods often have problems such as uneven gluing, glue precipitation and stratification, and low drying efficiency, this solution ensures the uniformity and fluidity of the glue, as well as the accuracy and consistency of the plywood gluing by arranging a rotatable stirring shaft 6 and a liftable roller brush 11 in the glue storage cylinder 5, thereby greatly improving production efficiency and ensuring the final quality of the product; in addition, the application of the hot air circulation system not only accelerates the drying process of the glue, but also ensures the consistency and uniformity of the glue drying, further improving product quality; at the same time, the system treats the hot and humid air through the active adsorption filter layer 19 during the exhaust process, thereby reducing environmental pollution.

[0029] Specifically, in this embodiment, the present solution mainly includes a support base 1; the plywood to be coated with glue is placed on the conveyor belt 2 on the upper surface of the support base 1. As the conveyor belt 2 moves, the plywood slowly moves forward according to a preset efficient processing sequence; when the plywood approaches the first processing chamber 3, the stirring shaft 6 in the glue storage barrel 5 starts to rotate under the drive of the first motor 12, driving the stirring blade 7 to quickly and evenly stir the glue in the glue storage barrel 5. This step ensures the uniformity and fluidity of the glue coating, which is crucial for improving the subsequent gluing effect. It can effectively avoid the sedimentation or stratification problems that may occur in the glue during long-term storage.

[0030] Next, the glued plywood moves into the first processing chamber 3, and the telescopic end of the electric push rod 8 located at the top of the first processing chamber 3 extends downward, driving the assembly seat 9 and the roller 10 inside it to slowly descend; as the roller 10 descends, the roller brush 11 thereon gradually approaches and contacts the surface of the passing plywood; at this time, the roller 10 starts to rotate driven by the second motor 13, and the roller brush 11 also rotates accordingly, evenly brushing the glue that has been mixed evenly in the glue storage cylinder 5 to the surface of the plywood; after the gluing process is completed, the plywood continues to move forward smoothly under the continuous drive of the conveyor belt 2, leaving the first processing chamber 3 and entering the second processing chamber 14.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, the brush assembly also includes: a first motor 12 arranged at the top position of the glue storage cylinder 5, and the output end of the first motor 12 is fixedly connected to the end key of the stirring shaft 6; a second motor 13 provided on the outer wall of the assembly seat 9, and the output end of the second motor 13 is fixedly connected to the end key of the roller shaft 10.

[0032] In this embodiment, the first motor 12 drives the stirring shaft 6 to rotate. As the stirring shaft 6 rotates, the stirring blade 7 fixed on the stirring shaft 6 also stirs the glue in the glue storage cylinder 5 quickly and evenly. The second motor 13 drives the roller 10 to rotate. The rotation of the roller 10 drives the rotation of the roller brush 11. The glue on the roller brush 11 is evenly brushed onto the surface of the plywood during the process of the roller brush 11 contacting and moving relative to the surface of the plywood.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the drying component includes: a second processing chamber 14 arranged on the support seat 1; a heating wire 15 arranged on the inner wall of the second processing chamber 14, and the heating wire 15 is distributed in a ring shape; and a group of circulation fans 16 symmetrically arranged at the top position of the inner cavity of the second processing chamber 14.

[0034] In this embodiment, the heating wire 15 is energized to release heat, heating the adjacent air to a set temperature. Since the heating wire 15 is designed to be evenly distributed in a circular shape on the inner wall of the second processing chamber 14, this layout effectively ensures that a uniformly distributed hot air environment can be formed inside the entire processing chamber. At the same time, a group of circulating fans 16 located at the top of the inner cavity of the second processing chamber 14 begins to rotate. The wind force they generate draws in the hot air gathered around the heating wire 15 and, through the propulsion of the fan blades, blows the hot air evenly to every corner of the processing chamber. This design creates an efficient hot air circulation system, allowing the hot air to cover and heat the surface of each plywood it passes through in all directions and without dead ends. Under the continuous circulation of hot air, the glue applied to the surface of the plywood quickly absorbs heat, and the solvent or moisture inside it evaporates faster due to the heat, thereby promoting the drying process of the glue. This hot air drying method not only significantly improves the drying efficiency, but also ensures that the glue can reach the ideal drying state evenly and quickly, thereby avoiding quality problems caused by uneven drying.

[0035] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the drying component further includes: a fan 17 arranged on the outer side wall of the second processing chamber 14 , one end of the fan 17 is connected to the second processing chamber 14 , and the other end of the fan 17 is connected to an air guide port 18 .

[0036] In this embodiment, when the fan 17 is in the exhaust mode, it will extract hot and humid air from the inside of the second processing chamber 14. The extracted hot and humid air is forced to be discharged to the outside of the second processing chamber 14 through the operation of the fan 17 and released into the environment through the air guide port 18. This process helps to reduce the humidity and temperature in the second processing chamber 14 and accelerate the drying process of the glue.

[0037] In a further preferred embodiment of the present invention, Figure 4As shown, an active adsorption filter layer 19 is provided in the air guide port 18 .

[0038] In this embodiment, in the exhaust mode, the hot and humid air discharged from the second processing chamber 14 will also pass through the air guide port 18 and the active adsorption filter layer 19. At this time, the filter layer will adsorb and remove harmful substances such as moisture in the air, reducing pollution to the environment.

[0039] In a further preferred embodiment of the present invention, Figure 2-4 As shown, the inner walls of the glue storage cylinder 5 and the second processing chamber 14 are both provided with temperature sensors 20 (PT100).

[0040] In this embodiment, by monitoring the temperature of the glue, it is possible to ensure that the glue is in the best working condition before coating, avoiding the increase in glue viscosity due to too low temperature, or the excessive fluidity of the glue due to too high temperature, which affects the coating quality; by monitoring the temperature in the second processing chamber 14, the output power of the heating wire 15 can be adjusted in real time to ensure that the temperature in the second processing chamber 14 is always maintained within the optimal drying range, thereby achieving rapid and uniform drying of the glue.

[0041] In a further preferred embodiment of the present invention, Figure 1 As shown, the first processing chamber 3 and the second processing chamber 14 are both box structures with open ends, wherein shielding curtains 21 are provided at both open ends of the second processing chamber 14 .

[0042] In this embodiment, the main function of the shielding curtain 21 is to reduce the heat exchange between the inside of the second processing chamber 14 and the external environment, maintain the temperature and humidity in the second processing chamber 14 stable, thereby ensuring the drying effect. At the same time, the shielding curtain 21 can also prevent dust and impurities from entering the second processing chamber 14 to a certain extent, thereby ensuring product quality.

[0043] Working Principle: When the device is in use, the plywood to be glued is placed on the conveyor belt 2. As the conveyor belt 2 continues to move, the plywood slowly moves forward in a preset sequence. When the plywood is about to enter the first processing chamber 3, the stirring shaft 6 located in the glue storage barrel 5 begins to rotate under the drive of the first motor 12. This rotational action causes the stirring blades 7 to quickly and evenly stir the glue in the glue storage barrel 5, effectively avoiding the sedimentation or stratification problems that may occur during long-term storage of the glue, ensuring the uniformity and fluidity of the glue. Then, the glue is controlled by the one-way valve 24 and flows along the glue barrel through the glue outlet 23 onto the plywood.

[0044] The glued plywood continues to move into the first processing chamber 3 driven by the conveyor belt 2. At this time, the telescopic end of the electric push rod 8 located at the top of the first processing chamber 3 extends downward, driving the assembly seat 9 and the roller 10 inside it to slowly descend. As the roller 10 descends, the roller brush 11 mounted thereon gradually approaches and contacts the surface of the passing plywood. At the same time, the roller 10 starts to rotate driven by the second motor 13, and the roller brush 11 also rotates accordingly. During this process, the glue on the roller brush 11 is evenly applied to the surface of the plywood due to the contact and relative movement with the surface of the plywood, thus achieving a precise gluing operation.

[0045] After the gluing process is completed, the plywood continues to move forward under the push of the conveyor belt 2, leaving the first processing chamber 3 and entering the second processing chamber 14; in the second processing chamber 14, the heating wire 15 is energized and releases heat, heating the adjacent air to a set temperature; because the heating wire 15 is designed in a ring shape and distributed on the inner wall of the second processing chamber 14, it can ensure that a uniformly distributed hot air environment is formed throughout the second processing chamber 14; at the same time, a group of circulating fans 16 located at the top of the inner cavity of the second processing chamber 14 begins to rotate, and the wind force they generate sucks in the hot air gathered around the heating wire 15, and the hot air is evenly blown to every corner of the second processing chamber 14 through the propulsion of the fan blades; this design creates an efficient hot air circulation system, so that the hot air can fully cover and heat the surface of each plywood it passes through without any dead ends;

[0046] Under the continuous circulation of hot air, the glue applied to the plywood surface quickly absorbs heat, and the solvent or moisture inside it evaporates faster due to the heat, thereby promoting the drying process of the glue. This hot air drying method not only significantly improves drying efficiency, but also ensures that the glue can reach the ideal drying state evenly and quickly, effectively avoiding quality problems caused by uneven drying.

[0047] When the fan 17 is in exhaust mode, it extracts hot and humid air from the interior of the second processing chamber 14. This hot and humid air is forcibly discharged by the fan 17 and released into the external environment through the air guide 18. During this process, the active adsorption filter layer 19 provided in the air guide 18 absorbs and removes moisture and other harmful substances in the air, further reducing pollution to the environment.

[0048] In addition, the entire system is also equipped with a temperature sensor 20 to monitor the glue temperature and the temperature in the processing chamber; by real-time monitoring and adjustment of parameters such as the output power of the heating wire 15 and the stirring speed of the stirring shaft 6, it can be ensured that the glue is in the best working state before coating and the temperature in the second processing chamber 14 is always kept within the optimal drying range.
