Description

Technical Field

[0001] This utility model relates to the field of single-roller glue applicator technology, and in particular to the cleaning structure of a single-roller glue applicator. Background Technology

[0002] In the industrial production field, adhesive coating processes are widely used in industries such as packaging, textiles, and electronics. Single-roller adhesive coaters have become one of the most common adhesive coating equipment due to their relatively simple structure, low cost, and convenient operation. Their working principle is mainly to uniformly coat the substrate surface with adhesive by rotating a single roller. With the improvement of industrial automation, the requirements for adhesive coating accuracy, efficiency, and stability are constantly increasing, and single-roller adhesive coaters are also constantly being improved and developed. However, in practical applications, the problem of adhesive sticking to the roller has always been one of the key factors restricting its performance improvement.

[0003] During operation, existing single-roller coating machines inevitably accumulate residual silicone material on the roller surface. Silicone is highly adhesive and cures quickly, easily forming a stubborn adhesive layer once it adheres to the roller. Traditional cleaning methods typically rely on manual disassembly of the roller for wiping or solvent cleaning, which is not only labor-intensive and time-consuming but may also lead to an increasingly thick adhesive layer due to incomplete cleaning, affecting the uniformity and precision of subsequent coating. Furthermore, frequent disassembly of the roller may cause wear and tear on mechanical parts, reducing the equipment's lifespan. Utility Model Content

[0004] In order to overcome the problem that the rollers of existing single-roller glue applicators are often difficult to clean due to residual silicone material adhering to them, this utility model provides a cleaning structure for single-roller glue applicators.

[0005] The technical solution is as follows: The cleaning structure of the single-roller glue applicator includes a processing table, a cleaning component, a single-roller drive component, and a glue dispensing component; the single-roller drive component is installed inside the processing table; the glue dispensing component is installed above the single-roller drive component; the cleaning component is installed below the single-roller drive component; the cleaning component includes a lifting base, a lifting cylinder, a pressure pump, a spray valve, and a lifting rod; the single-roller drive component includes a single roller and a roller servo motor; the glue dispensing component includes a dual-axis lead screw motor and a glue application control valve; the single roller is installed inside the processing table; a roller servo motor is installed on one side of the single roller, and the roller servo motor drives the single roller to rotate; a lifting base is installed below the single roller.

[0006] Furthermore, lifting rods are provided on both sides of the front end of the lifting base, and the lifting rods are fixedly connected to the lifting base, and the lifting rods are vertically slidably connected along the holes of the processing table.

[0007] Furthermore, a pressure pump is installed at the upper end of the lifting base, and the pressure pump is fixedly connected to the lifting base.

[0008] Furthermore, a lifting cylinder is provided at the lower end of the lifting base, and the housing of the lifting cylinder is fixedly connected to the processing table, and the output end of the lifting cylinder is fixedly connected to the lifting base.

[0009] Furthermore, an injection valve is installed at the upper end of the pressurization pump, and the output end of the pressurization pump is connected to the input end of the injection valve.

[0010] Furthermore, a dual-axis lead screw machine is installed above the single roller, and the housing of the dual-axis lead screw machine is fixedly connected to the processing table.

[0011] Furthermore, the output end of the dual-axis ball screw machine is equipped with a glue application control valve, and the glue application control valve is fixedly connected to the output end of the dual-axis ball screw machine.

[0012] The beneficial effects are as follows: This invention, through preset control commands of the cleaning components, initiates the operation of the lifting cylinder. The piston inside the lifting cylinder, propelled by compressed gas, generates an upward thrust, thereby driving the lifting base to rise vertically. During the lifting base's ascent, the lifting rod plays a crucial supporting and guiding role. Its two ends are securely connected to the lifting base and the fixed structure, respectively. Utilizing high-precision linear motion bearings and guide rails, it effectively suppresses swaying and deviation during the lifting process, significantly improving the lifting stability of the lifting base. As the lifting base continues to rise, the pressure pump installed on it is gradually raised to a position directly below the single roller. At this point, the pressure pump begins operation, and its internal impeller operates at high speed. The rotation pressurizes the stored cleaning agent, which is then transported through a pipeline to the spray valve. Under high pressure, the cleaning agent is sprayed upwards at high speed from the spray valve. The spray valve has a precisely designed nozzle structure to ensure that the sprayed cleaning liquid forms a high-speed jet with specific pressure and angle, directly acting on the surface of the single roller. At the same time, the roller servo motor receives a control signal and starts working. Its output shaft is connected to the roller shaft of the single roller through a coupling, driving the single roller to rotate at a set speed. The high-speed cleaning liquid powerfully washes the surface of the single roller. Combined with the rotation of the single roller, the high-speed cleaning liquid can cover the entire outer circumference of the single roller, achieving a comprehensive cleaning function around the outer circumference of the single roller.

[0013] With the setting of the dispensing component, the motor inside the dual-axis lead screw machine runs, driving the lead screw to perform precise transmission, thereby driving the glue application control valve at its output end to move and adjust in the horizontal and vertical directions. The motion control signal of the dual-axis lead screw machine can accurately control the movement trajectory and speed of the glue application control valve. When the single roller rotates to convey materials, the glue application control valve moves to the corresponding position according to the preset program, uniformly coating the material surface on the single roller with glue, thereby realizing the glue application on the material on the single roller.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: As Figures 1-5 As shown, the cleaning structure of the single-roller glue applicator includes a processing table 1, a cleaning assembly 2, a single-roller drive assembly 3, and a glue dispensing assembly 4. The single-roller drive assembly 3 is installed inside the processing table 1. The glue dispensing assembly 4 is installed above the single-roller drive assembly 3. The cleaning assembly 2 is installed below the single-roller drive assembly 3. The cleaning assembly 2 includes a lifting base 201, a lifting cylinder 202, a pressure pump 203, a spray valve 204, and a lifting rod 205. The single-roller drive assembly 3 includes a single roller 301 and a roller servo motor 302. The glue dispensing assembly 4 includes a dual-axis lead screw motor 401 and a glue dispensing control valve 402. The single roller 301 is installed inside the processing table 1. The roller servo motor 302 is installed on one side of the single roller 301, and the roller servo motor 302 drives the single roller 301 to rotate. The lifting base 201 is installed below the single roller 301.

[0022] Lifting rods 205 are provided on both sides of the front end of the lifting base 201, and the lifting rods 205 are fixedly connected to the lifting base 201. The lifting rods 205 are vertically slidably connected along the holes of the processing table 1.

[0023] A pressure pump 203 is provided at the upper end of the lifting base 201, and the pressure pump 203 is fixedly connected to the lifting base 201.

[0024] A lifting cylinder 202 is provided at the lower end of the lifting base 201, and the housing of the lifting cylinder 202 is fixedly connected to the processing table 1, and the output end of the lifting cylinder 202 is fixedly connected to the lifting base 201.

[0025] The upper end of the pressurizing pump 203 is provided with an injection valve 204, and the output end of the pressurizing pump 203 is connected to the input end of the injection valve 204.

[0026] Upon receiving the preset control command from the cleaning component 2, the lifting cylinder 202 begins operation. The piston inside the lifting cylinder 202, propelled by compressed gas, generates an upward thrust, driving the lifting base 201 to rise vertically. During the ascent of the lifting base 201, the lifting rod 205 plays a crucial supporting and guiding role. Its two ends are securely connected to the lifting base 201 and the fixed structure, respectively. Thanks to the high-precision linear motion bearings and guide rails, swaying and deviation during the lifting process are effectively suppressed, significantly improving the lifting stability of the lifting base 201. As the lifting base 201 continues to rise, the pressure pump 203 installed on it is gradually raised to a position directly below the single roller 301. At this point, the pressure pump 203 begins operation, its internal impeller rotating at high speed, pumping the stored... The stored cleaning agent is pressurized and then transported through a pipeline to the spray valve 204. Under high pressure, the cleaning agent is sprayed upward at high speed from the spray valve 204. The spray valve 204 has a precisely designed nozzle structure to ensure that the sprayed cleaning liquid forms a high-speed jet with specific pressure and angle, which directly acts on the surface of the single roller 301. At the same time, the roller servo motor 302 receives the control signal and starts to work. Its output shaft is connected to the roller shaft of the single roller 301 through a coupling, driving the single roller 301 to rotate at a set speed. The high-speed cleaning liquid powerfully washes the surface of the single roller 301. With the rotation of the single roller 301, the high-speed cleaning liquid can cover the entire outer circumference of the single roller 301, realizing a comprehensive cleaning function for the outer circumference of the single roller 301.

[0027] Example 2: Based on Example 1, such as Figures 1-5 As shown, a dual-axis lead screw machine 401 is arranged above the single roller 301, and the housing of the dual-axis lead screw machine 401 is fixedly connected to the processing table 1.

[0028] The output end of the dual-axis ball screw machine 401 is equipped with a glue application control valve 402, and the glue application control valve 402 is fixedly connected to the output end of the dual-axis ball screw machine 401.

[0029] With the setting of the dispensing component 4, the motor inside the dual-axis lead screw machine 401 operates, driving the lead screw to perform precise transmission, thereby driving the glue application control valve 402 at its output end to move and adjust in the horizontal and vertical directions. The motion control signal of the dual-axis lead screw machine 401 can accurately control the movement trajectory and speed of the glue application control valve 402. When the single roller 301 rotates to convey materials, the glue application control valve 402 moves to the corresponding position according to the preset program, and evenly coats the material surface on the single roller 301 with glue, thereby realizing the glue application on the material on the single roller 301.
