Description

Technical Field

[0001] This invention belongs to the field of adhesive coating technology, specifically relating to an adhesive coating roller and its adhesive coating system that facilitates uniform adhesive application. Background Technology

[0002] With the continuous advancement of gluing technology, more and more gluing devices need to perform precise work on the amount of glue and the gluing effect when applying glue to wood boards. Animal glue is one of the most widely used adhesives in the printing and packaging industry. It has undergone in-depth processing in terms of bonding performance, corrosion prevention, odor elimination, defoaming, and enhancing its flowability, making the coating more uniform and easier to use. However, when using animal glue to apply glue to the surface of wood boards, the precision of the gluing process needs to be even higher.

[0003] Existing glue-applying devices cannot control their operation intelligently based on the roughness of the wood board, thus failing to effectively improve glue-applying quality. During the glue-applying process, excessive glue discharge is prone to occur, leading to glue layering on the wood board surface and affecting the glue-applying quality. Roughness affects the flowability of the glue, and this phenomenon has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a glue-applying roller and its glue-applying system for existing material collection devices, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a glue-applying roller and its glue-applying system for easy uniform glue application, comprising a glue-applying device and an intelligent glue-applying system, characterized in that: the glue-applying device includes a bracket, a motor is fixedly installed on the rear side of the bracket, two rotating rollers are connected to the middle bearing of the bracket, a transmission mechanism is fixedly installed inside the motor, a wooden board is placed between the two rotating rollers, the rear ends of the two rotating rollers are fixedly connected to the output end of the transmission mechanism, a glue-applying mechanism is provided inside the two rotating rollers, and a roughness detector is fixedly installed on the right end of the bracket, the roughness detector being used to detect the surface roughness value of the wooden board.

[0006] The present invention further describes that the adhesive application mechanism includes a pneumatic pump, which is fixedly connected to the inner wall of the rotating roller. The inner pipe of the pneumatic pump is connected to several telescopic cavities. The outer surfaces of both rotating rollers are made of elastic material and have several small holes. Elastic cavities are fixedly connected to the outer ends of the telescopic cavities. Several small holes are formed on the outer surface of the elastic cavities. A transfer pump is fixedly installed on the inner wall of the rotating roller. The elastic cavities are fixedly connected to the inner wall of the rotating roller. Corresponding pipes connect the small holes on the outer surface of the elastic cavities to the small holes on the outer surface of the rotating rollers. Several throttling valves are connected to the outer pipe of the transfer pump. All throttling valves are connected to the elastic cavity pipes. The transfer pump is connected to an external adhesive pipe. The adhesive is made of animal glue.

[0007] The present invention further illustrates that the intelligent adhesive coating system includes a data acquisition module, an intelligent conversion module, and an intelligent control module. The data acquisition module is electrically connected to a roughness detector. The intelligent conversion module is electrically connected to both the data acquisition module and the intelligent control module. The intelligent control module is electrically connected to a motor, a transfer pump, a pneumatic pump, and a throttle valve.

[0008] The data acquisition module is used to collect surface roughness data of the wood board in the roughness tester. The intelligent conversion module is used to convert the roughness of the wood board and input the result into the intelligent control module. The intelligent control module is used to control the operation of the motor, transfer pump, air pump and throttle valve.

[0009] The present invention further illustrates that the intelligent adhesive application system includes the following operating steps:

[0010] S1. Intelligent adhesive application system in operation;

[0011] S2. The electric drive controls the operation of the roughness tester, which detects the roughness of the wood board.

[0012] S3. The data acquisition module collects the roughness data of the wood board and inputs it into the intelligent conversion module. The intelligent conversion module converts the data into a structural value and inputs it into the intelligent control module.

[0013] S4. The intelligent control module drives the motor to transport the wood board and controls the motor speed according to the roughness value of the wood board, thereby controlling the transport speed. At the same time, it drives the transport pump and the air pump to operate and perform high-precision control of the glue application process.

[0014] S5. The glue application is completed and the intelligent glue application system stops running. If the next glue application is required, repeat S1 to S4.

[0015] The present invention further explains that the high-precision control of the glue application process and the protection of the wooden board in step S4 include the following steps:

[0016] S4.1 The intelligent control module controls the amount of gas input into the telescopic cavity by the air pump according to the roughness of the wood board;

[0017] S4.2 The intelligent control module controls the operation of the transfer pump to input adhesive into the elastic cavity, and controls the throttle valve according to the roughness of the wood board to control the amount of adhesive entering the elastic cavity.

[0018] S4.2 The intelligent control module controls the motor's operating status based on the roughness of the wood board to protect the wood board.

[0019] The present invention further explains that in S4, the intelligent control module drives the motor to operate, performs the transmission work of the wooden board, and controls the motor speed according to the roughness value of the wooden board. The motor drives the transmission mechanism, which causes the transmission mechanism to change the rotation speed of the rotating roller. The transmission speed of the wooden board from right to left between the two rotating rollers is controlled.

[0020] The present invention further explains that in S4.1, the intelligent control module controls the amount of gas input to the telescopic cavity by the air pressure pump according to the roughness of the wood board, thereby controlling the extension length of the telescopic cavity, changing the degree to which the telescopic cavity drives the elastic cavity to expand outward, thereby bringing the two rotating rollers closer together, changing the squeezing force of the two rotating rollers on the outer surface of the wood board, and controlling the gluing effect during gluing.

[0021] The present invention further explains that in S4.2, the intelligent control module controls the operation of the transfer pump to input adhesive into the elastic cavity, and controls the throttling valve according to the roughness of the wood board to control the amount of adhesive entering the elastic cavity.

[0022] The present invention further explains that in S4.3, when the roughness value of the wood board reaches the maximum value of the system, it indicates that the surface roughness of the wood board does not meet the surface roughness of a qualified wood board. In order to stop the loss in time, the drive motor is stopped, so that the operator knows that the quality of the wood board is unqualified and stops the glue application work on the wood board, thus saving production costs.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention adopts an intelligent glue application system, a glue application mechanism and a motor. The motor drives the transmission mechanism to run, and the transmission mechanism drives two rotating rollers to rotate through the output end. The motor speed is controlled according to the roughness of the wood board, thereby controlling the wood board transmission speed. At the same time, the glue application mechanism is controlled to operate intelligently according to the roughness of the wood board, thereby improving the glue application quality.

[0031] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-5 This invention provides a technical solution: a glue-applying roller and its glue-applying system for easy uniform glue application, comprising a glue-applying device and an intelligent glue-applying system. The glue-applying device includes a bracket 1, a motor 2 fixedly mounted on the rear side of the bracket 1, two rotating rollers 3 connected to the middle bearing of the bracket 1, a transmission mechanism fixedly mounted inside the motor 2, a wooden board placed between the two rotating rollers 3, and the rear ends of both rotating rollers 3 fixedly connected to the output end of the transmission mechanism. A glue-applying mechanism is provided inside each of the two rotating rollers 3. A roughness detector 4 is fixedly mounted on the right end of the bracket 1, used to detect the surface roughness value of the wooden board. The intelligent glue-applying system is connected to an external power supply and the motor 2. The surface roughness detector 4 and the glue application mechanism are electrically connected. The operator holds the wooden board and pushes it between the rotating rollers 3. At this time, the intelligent glue application system starts to run through the external power supply. The intelligent glue application system controls the operation of the surface roughness detector 4 through electric drive. The surface roughness detector 4 detects the roughness of the wooden board surface and then controls the rotation of the motor 2 through electric drive. The motor 2 drives the transmission mechanism to run. The transmission mechanism drives the two rotating rollers 3 to rotate through the output end and controls the speed of the motor 2 according to the roughness of the wooden board, thereby controlling the transmission speed of the wooden board. At the same time, the glue application mechanism is controlled to operate intelligently according to the roughness of the wooden board, thereby improving the glue application quality.

[0033] The adhesive application mechanism includes an air pump 5, which is fixedly connected to the inner wall of a rotating roller 3. Several telescopic chambers 6 are connected to the inner pipe of the air pump 5. The outer surfaces of the two rotating rollers 3 are made of elastic material and have several small holes. Elastic chambers 8 are fixedly connected to the outer ends of the telescopic chambers 6, and several small holes are opened on the outer surface of the elastic chambers 8. A transfer pump 9 is fixedly installed on the inner wall of the rotating roller 3. The elastic chambers 8 are fixedly connected to the inner wall of the rotating roller 3, and the small holes on the outer surface of the elastic chambers 8 are connected to the corresponding small holes on the outer surface of the rotating roller 3 via pipes. Several throttling valves 7 are connected to the outer pipe of the transfer pump 9, and all throttling valves 7 are connected to the pipes of the elastic chambers 8. The transfer pump 9 is connected to an external adhesive pipe. The adhesive is made of animal glue. The intelligent adhesive application system is electrically connected to the transfer pump 9, the air pump 5, and the throttling valves 7 respectively. Through the above steps, the intelligent adhesive application system... When the glue application system is running, the air pump 5 injects gas into the telescopic cavity 6 through its inner pipe, and controls the amount of gas injected according to the roughness of the wood board. This causes the telescopic cavity 6 to extend and push against the elastic cavity 8 to expand outward. The elastic material on the outer side of the rotating roller 3 is squeezed and deformed outward, changing the diameter of the two rotating rollers 3 and the squeezing force on the wood board. The electric drive controls the operation of the transfer pump 9, which draws glue from the outside and injects it into the throttle valve 7 through the pipe. Then, it passes through the throttle valve 7 and is injected into the elastic cavity 8 through the pipe. Finally, the glue enters the pipe through the small hole in the elastic cavity 8 and is discharged onto the wood board through the small hole on the outer surface of the rotating roller 3, thus performing the glue application work on the wood board. The throttle valve 7 is controlled according to the roughness of the wood board to control the amount of glue discharged, making the glue application work intelligent and improving the glue application quality.

[0034] The intelligent adhesive application system includes a data acquisition module, an intelligent conversion module, and an intelligent control module. The data acquisition module is electrically connected to the roughness detector 4. The intelligent conversion module is electrically connected to both the data acquisition module and the intelligent control module. The intelligent control module is electrically connected to the motor 2, the transfer pump 9, the air pump 5, and the throttle valve 7.

[0035] The data acquisition module is used to collect the surface roughness data of the wooden board in the roughness tester 4. The intelligent conversion module is used to convert the roughness of the wooden board and input the result into the intelligent control module. The intelligent control module is used to control the operation of the motor 2, the transfer pump 9, the air pump 5, and the throttle valve 7.

[0036] The intelligent adhesive application system includes the following operating steps:

[0037] S1. Intelligent adhesive application system in operation;

[0038] S2. The electric drive controls the roughness tester 4 to operate, and the roughness tester 4 detects the roughness of the wood board.

[0039] S3. The data acquisition module collects the roughness data of the wood board and inputs it into the intelligent conversion module. The intelligent conversion module converts the data into a structural value and inputs it into the intelligent control module.

[0040] S4. The intelligent control module drives the motor 2 to transport the wood board and controls the speed of the motor 2 according to the roughness value of the wood board, thereby controlling the transmission speed. At the same time, it drives the transmission pump 9 and the air pump 5 to operate, and performs high-precision control of the glue application process.

[0041] S5. The glue application is completed and the intelligent glue application system stops running. If the next glue application is required, repeat S1 to S4.

[0042] The high-precision control of the glue application process and the protection of the wood panels in S4 include the following steps:

[0043] S4.1 The intelligent control module controls the amount of gas input to the telescopic cavity 6 by the air pump 5 according to the roughness of the wood board.

[0044] S4.2 The intelligent control module controls the operation of the transfer pump 9 to input adhesive into the elastic cavity 8, and controls the throttle valve 7 according to the roughness of the wood board to control the amount of adhesive entering the elastic cavity 8.

[0045] S4.3 The intelligent control module controls the operating status of motor 2 according to the roughness of the wood board to protect the wood board.

[0046] In S4, the intelligent control module drives motor 2 to transport the wooden board and controls the speed of motor 2 according to the surface roughness of the board. Motor 2 drives the transmission mechanism, which in turn changes the speed of the rotating roller 3. The speed at which the wooden board is transported from right to left between the two rotating rollers 3 is controlled. R is the surface roughness of the wooden board.

[0047] Among them, V 传 R is the speed at which motor 2 drives the wooden board for transmission. min V represents the minimum surface roughness of the wood panel. max The maximum speed at which motor 2 drives the wooden board for transmission is determined by the surface roughness of the wooden board. The greater the surface roughness of the wooden board, the slower the transmission speed of motor 2 drives the wooden board. This is to ensure uniform glue application later and reduce the transmission speed to avoid uneven glue application on the wooden board. Conversely, the smaller the surface roughness of the wooden board, the faster the transmission speed of motor 2 drives the wooden board. In this case, the glue can fill the wooden board relatively easily, thereby speeding up the glue application and increasing the production speed.

[0048] In S4.1, the intelligent control module controls the amount of gas input from the air pump 5 into the telescopic cavity 6 based on the roughness of the wood board, thereby controlling the extension length of the telescopic cavity 6. This changes the degree to which the telescopic cavity 6 drives the elastic cavity 8 to expand outward, thus bringing the two rotating rollers 3 closer together and changing the pressure exerted by the two rotating rollers 3 on the outer surface of the wood board, thereby controlling the glue application effect during glue application.

[0049] When Rmid <R<R max At that time, R max R is the maximum surface roughness of the wooden board supported by the system. mid This is the median roughness value taken by the roughness tester 4 after testing all the previous wooden boards during the use of this device: Wherein, P represents the degree to which the pneumatic pump 5 drives the telescopic cavity 6 to expand against the rotating roller 3. max The air pump 5 drives the telescopic cavity 6 to push the rotating roller 3 to its maximum expansion. The greater the surface roughness of the wood board, the greater the squeezing force of the two rotating rollers 3 on the outer surface of the wood board, so that the rotating rollers 3 can fit the wood board more closely. This makes it easier for the glue to fill the grooves in the wood board during subsequent glue discharge, improving the glue application effect and avoiding glue layering, which affects the glue application quality. Conversely, the smaller the surface roughness of the wood board, the less squeezing force the two rotating rollers 3 exert on the outer surface of the wood board. This ensures smooth glue application while increasing the transmission speed of the wood board and speeding up the glue application process.

[0050] When R min <R≤R mid Time: P = P min P min The pneumatic pump 5 drives the telescopic cavity 6 to expand to the minimum extent that the rotating roller 3 expands. At this point, the surface roughness of the wood board is small. In order to speed up the gluing speed of the wood board, the pressure on the wood board is reduced, but it can still squeeze against the wood board, ensuring uniform gluing while avoiding the phenomenon of reduced wood board transmission speed.

[0051] In S4.2, the intelligent control module controls the operation of the transfer pump 9 to input adhesive into the elastic cavity 8, and controls the throttle valve 7 according to the roughness of the wood board to control the amount of adhesive entering the elastic cavity 8.

[0052] When R mid <R<R max When: For the greater the surface roughness of the wood board, the more glue the throttle valve 7 controls to enter the elastic chamber 8. At this time, the greater the roughness, the more grooves there are on the surface of the wood board. Therefore, the amount of glue is increased to ensure that the wood board is fully and evenly coated with glue, ensuring smooth glue application and improving the glue application effect. For the smaller the surface roughness of the wood board, the less glue the throttle valve 7 controls to enter the elastic chamber 8. This avoids the phenomenon of glue accumulation on the surface of the wood board due to excessive glue discharge, and prevents the glue quality of the wood board from being affected by excessive glue discharge. This improves the glue application precision of the wood board and enhances the glue application effect.

[0053] When R min <R≤R mid Time: Q = Q mid Q is the amount of adhesive entering the elastic cavity 8. midThe throttle valve 7 controls the normal amount of glue to enter the elastic chamber 8. At this time, the roughness of the wood board is small. Using the normal amount of glue can ensure that the glue is not wasted and avoid over-gluing the wood board, which will affect the glue coating quality.

[0054] In S4.3, when the roughness value of the wood board reaches the maximum value of the system, R = R max This indicates that the surface roughness of the wood board does not meet the acceptable surface roughness standard. To prevent further damage, the drive motor 2 is stopped, thus informing the operator that the wood board is substandard and allowing them to stop applying glue to the board, thereby saving production costs.
