Description

Technical Field

[0001] This invention relates to the field of sheet metal coating technology, and more specifically, to a sheet metal adhesive mixing machine with an integrated roller coating mechanism. Background Technology

[0002] As the requirements for adhesive coating processes in the board processing industry continue to increase, the roller coating mechanism of traditional board adhesive mixing machines has gradually revealed the following problems: Currently, existing equipment relies on manual sampling or offline testing. Most of them cannot monitor the glue coating quality in real time and require manual inspection. However, manual inspection is difficult to detect and correct abnormal glue content in a timely manner during mass production, which can easily lead to batch defects, material waste, and increased rework costs. To address this, we propose a board glue mixing machine with an integrated roller coating mechanism. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sheet metal mixing machine with an integrated roller coating mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a board mixing machine with an integrated roller coating mechanism, comprising a working frame and a transmission assembly, a control cabinet fixedly installed on one side of the working frame, several sets of board conveying rollers arranged in parallel inside the working frame, a synchronous wheel installed at one end of each board conveying roller, a synchronous belt being provided on the outside of each synchronous wheel, a bracket installed on the top of the working frame, a mixing tank installed on the top of the bracket, a lid installed on the top of the mixing tank, a motor installed on the top of the lid, the power drive end of the motor connected to a stirring paddle, a discharge pipe with a control valve installed at the bottom of the mixing tank, support frames installed on the top and bottom of the working frame, and infrared thermal imaging devices installed on the top and bottom of the two support frames; The transmission assembly includes a mounting plate installed on one side of the work frame plate. A motor is mounted on the outer side of the mounting plate. Conical roller 1 and conical roller 2 are connected to the outer side of the mounting plate, respectively. The diameter of conical roller 1 gradually decreases from left to right, and the diameter of conical roller 2 gradually increases from left to right. A fixed seat is installed on one side of the mounting plate. A transmission belt is provided on the outer side of conical roller 1 and conical roller 2. A synchronous pulley 2 is installed at one end of conical roller 1, and a synchronous pulley 3 is installed at one end of conical roller 2. Glue-applying roller 1 and glue-applying roller 2 are connected inside the work frame plate. Gear 1 and gear 2 are installed at one end of glue-applying roller 1 and glue-applying roller 2, respectively. A synchronous pulley 4 is installed on one side of gear 2. A synchronous belt 2 is provided on the outer side of synchronous pulley 4 and synchronous pulley 3. A motor is installed inside the fixed seat. A lead screw is connected to the output end of the motor. A movable frame is connected to the outer side of the lead screw. A guide plate is installed on the top of the movable frame. A guide groove is opened on the inner side of the fixed seat, and a sleeve plate is installed on the outer side of the movable frame.

[0005] Preferably, the power drive end of motor two is connected to conical roller one.

[0006] Preferably, the transmission belt is made of rubber and is located inside the sleeve plate.

[0007] Preferably, a timing belt is installed outside the timing pulley 2, and the timing pulley 2 drives all the timing pulleys 1 to drive synchronously through the timing belt 1.

[0008] Preferably, gear one is located directly above gear two, and gear one meshes with the teeth of gear two to drive the first and second glue-applying rollers to rotate.

[0009] Preferably, the movable frame is threadedly connected to the lead screw and confined inside the fixed seat, and the lead screw is movably connected inside the fixed seat via a bearing.

[0010] Preferably, the guide plate is slidably connected inside the guide groove to limit the movement direction of the moving frame.

[0011] Preferably, the control valve of the discharge pipe is used to precisely control the amount of adhesive discharged from the mixing tank.

[0012] The technical effects and advantages of this invention are as follows: 1. In use, this invention utilizes tapered rollers one and two with diameters that gradually change in opposite directions, combined with an elastic rubber transmission belt, to construct a dynamically adjustable transmission system. Furthermore, a motor-driven screw drives the moving frame and the sleeve plate, precisely controlling the contact position of the transmission belt on the tapered rollers, thereby achieving stepless speed regulation of the coating roller rotation speed. This design breaks the limitation of the fixed transmission ratio of traditional roller coating machines, allowing for real-time adjustment of the matching relationship between the coating speed and the board conveying speed. This significantly improves the equipment's adaptability to multi-variety, small-batch production scenarios, reduces downtime caused by specification changes, and improves overall production efficiency.

[0013] 2. In use, the equipment is equipped with infrared thermal imaging devices at the top and bottom of the work stand to monitor the temperature distribution of the adhesive layer on the board surface in real time. When a local temperature abnormality is detected, a signal is immediately sent to the control cabinet. The control cabinet can quickly adjust the amount of adhesive discharged from the discharge pipe and simultaneously start the reverse rotation of the two motors and the motor drive screw to adjust the position of the transmission belt. The reverse rotation of the two motors causes the board to be conveyed in reverse for re-coating. The motor drive screw adjusts the position of the transmission belt, changing the speed of the coating roller to better match the coating speed with the characteristics of the board, thereby improving the coating effect. This combination of bidirectional coating and dynamic adjustment can accurately correct local coating defects, ensuring the uniformity of adhesive coating on the upper and lower surfaces of the board, and meeting the high standards of coating quality required for high-end board processing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As attached Figures 1-5 The integrated roller coating mechanism of the sheet material mixing machine shown includes a work frame plate 1 and a transmission assembly 2. A control cabinet 3 is fixedly installed on one side of the work frame plate 1. Several sets of sheet material conveying rollers 4 are arranged in parallel inside the work frame plate 1. A synchronous wheel 5 is installed at one end of each sheet material conveying roller 4. A synchronous belt 6 is arranged on the outside of each synchronous wheel 5. A bracket 7 is installed on the top of the work frame plate 1. A mixing tank 8 is installed on the top of the bracket 7. A lid 9 is installed on the top of the mixing tank 8. A motor 10 is installed on the top of the lid 9. The power drive end of the motor 10 is connected to a stirring paddle 11. A discharge pipe 12 with a control valve is installed at the bottom of the mixing tank 8. The control valve of the discharge pipe 12 is used to precisely control the amount of adhesive discharged from the mixing tank 8. Support frames 13 are installed on the top and bottom of the work frame plate 1. Infrared thermal imaging devices 14 are installed on the top and bottom of the two support frames 13. The transmission assembly 2 includes a mounting plate 21 installed on one side of the work frame plate 1. A second motor 22 is mounted on the outer side of the mounting plate 21. A first conical roller 23 and a second conical roller 24 are respectively connected to the outer side of the mounting plate 21. The diameter of the first conical roller 23 gradually decreases from left to right, and the diameter of the second conical roller 24 gradually increases from left to right. The power drive end of the second motor 22 is connected to the first conical roller 23. A fixed seat 25 is installed on one side of the mounting plate 21. The outer sides of the first conical roller 23 and the second conical roller 24 are shared. There is a drive belt 26, and a synchronous pulley 27 is installed at one end of the conical roller 23. The synchronous belt 6 is sleeved on the outside of the synchronous pulley 27. The synchronous pulley 27 drives all the synchronous pulleys 5 synchronously through the synchronous belt 6. A synchronous pulley 3 28 is installed at one end of the conical roller 24. The inside of the work frame plate 1 is connected to the glue coating roller 220 and the glue coating roller 29 respectively. Gear 1 210 and gear 211 are installed at one end of the glue coating roller 220 and the glue coating roller 29 respectively. Gear 1 210 is located at the gear 211. Directly above 211, gear 210 meshes with gear 211 at their teeth to drive coating roller 220 and coating roller 29 to rotate. A synchronous pulley 212 is mounted on one side of gear 211. A synchronous belt 213 is provided on the outside of synchronous pulley 212 and synchronous pulley 28. A motor 214 is mounted inside one side of the fixed base 25. A lead screw 215 is connected to the output end of the motor 214. A movable frame 216 is connected to the outside of the lead screw 215. The movable frame 216 is connected via a threaded connection. The movable frame 216 is connected to the lead screw 215 and confined inside the fixed base 25. The lead screw 215 is movably connected inside the fixed base 25 via a bearing. A guide plate 217 is installed on the top of the movable frame 216. A guide groove 218 is opened on one side of the inside of the fixed base 25. The guide plate 217 is slidably connected inside the guide groove 218 to limit the movement direction of the movable frame 216. A sleeve plate 219 is installed on the outer side of the movable frame 216. The transmission belt 26 is made of rubber and is located inside the sleeve plate 219.

[0022] The diameter of conical roller 23 gradually decreases from left to right, while the diameter of conical roller 24 gradually increases from left to right. The two are connected by a transmission belt 26, which is made of rubber and has elastic deformation capability to adapt to the adjustment of the contact radius caused by the change in the diameter of the conical rollers. When the transmission belt 26 moves to the right, its contact radius with conical roller 24 increases. With the speed of motor 22 remaining constant, the speed of conical roller 24 decreases. After the speed of conical roller 24 decreases, the speed of coating roller 29 and coating roller 220 are reduced synchronously through synchronous belt 213. Motor 214 drives lead screw 215 to rotate, and lead screw 215 drives moving frame 216 to move horizontally along guide groove 218 through thread transmission. The displacement of moving frame 216 causes sleeve plate 219 to move synchronously, and sleeve plate 219 pushes transmission belt 26 to move, thereby adjusting the contact position of transmission belt 26 on tapered roller 1 23 and tapered roller 24. The sliding connection between guide plate 217 and guide groove 218 restricts the movement direction of moving frame 216, avoids displacement deviation caused by mechanical vibration, and improves equipment stability. The infrared thermal imaging device 14 monitors the temperature distribution of the adhesive layer on the board surface in real time and sends a feedback signal to the control cabinet 3. When the amount of adhesive is sufficient, the adhesive layer dissipates heat slowly and the temperature is high. When the amount of adhesive is insufficient, the adhesive layer dissipates heat quickly and the temperature is low. The infrared thermal imaging device 14 judges the uniformity of adhesive application by detecting temperature differences. If a local temperature abnormality is detected, it immediately sends a feedback signal to the control cabinet 3. The control cabinet 3 adjusts the amount of adhesive discharged from the discharge pipe 12 or stops the machine for maintenance.

[0023] The working principle of this invention is as follows: The motor 22 is started by the control cabinet 3, and its power output end drives the conical roller 23 to rotate. The conical roller 23 drives the conical roller 24 to rotate synchronously through the transmission belt 26. The synchronous wheel 27 at one end of the conical roller 23 drives the synchronous wheel 5 of all the board conveying rollers 4 synchronously through the synchronous belt 6, thereby realizing the horizontal conveying of the board. The glue coating roller 220 and the glue coating roller 29 are set in the position where there are no board conveying rollers 4. Two infrared thermal imaging devices 14 are set in the gap to facilitate the detection of the board coating effect. The motor 10 inside the mixing tank 8 drives the stirring paddle 11 to rotate. After the glue is mixed, the glue liquid is quantitatively output through the control valve of the discharge pipe 12. The synchronous wheel 28 at one end of the conical roller 24 drives the synchronous wheel 212 through the synchronous belt 213. At this time, the synchronous wheel 212 drives the gear 211 to rotate. The gear 211 meshes with the gear 210 to drive the coating roller 220 and the coating roller 29 to rotate, and synchronously roll the glue liquid onto the upper and lower surfaces of the board. After coating, the board continues to be conveyed forward. The infrared thermal imaging device 14 monitors the temperature distribution of the glue layer on the board surface in real time. If insufficient glue is detected in some areas, a signal is sent to the control cabinet 3 to adjust the glue output of the discharge pipe 12. Furthermore, when it is necessary to adjust the amount of adhesive dispensed from the discharge pipe 12, the control cabinet 3 simultaneously starts motor 22 and motor 214. Motor 22 rotates in the reverse direction, causing the board conveying roller 4 to transport the board in the reverse direction for re-coating. At this time, motor 214 drives the lead screw 215 to rotate. The lead screw 215 drives the moving frame 216 to move horizontally along the guide groove 218 through the threaded transmission. The sleeve plate 219 on the outer side of the moving frame 216 drives the transmission belt 26 to move. Since the diameter of the conical roller 23 gradually decreases from left to right and the diameter of the conical roller 24 gradually increases from left to right, when the transmission belt 26 moves to the right, its contact radius with the conical roller 24 increases, resulting in a decrease in the rotation speed of the conical roller 24. After the rotation speed of the conical roller 24 decreases, the rotation speed of the coating roller 29 decreases synchronously through the synchronous belt 213, slowing down the coating speed and thus improving the coating effect. After the coating is completed, motor 22 rotates forward again to transport the board.
