Description

Technical Field

[0001] The invention relates to an ultrasonic cleaning device and a cleaning method, in particular to an ultrasonic cleaning device and a method suitable for cleaning a gluing roller of a packaging box. Background Art

[0002] In the production process of packaging boxes, the packaging machine uses the glue roller to apply latex to bond the packaging boxes. After the glue roller completes the gluing work, if the glue roller is not cleaned in time, the latex will condense on the surface of the glue roller, which will affect the smoothness of the surface of the glue roller, and then affect the gluing effect of the glue roller, and finally cause the produced packaging boxes to fail to meet the production quality requirements. Therefore, the glue roller needs to be cleaned in time after the production of the packaging boxes is completed.

[0003] At present, an ultrasonic cleaning device is usually used to clean the glue roller. The ultrasonic cleaning device is a device that uses the physical effect of ultrasound to clean dirt on the surface of an object. Its working principle is mainly based on the cavitation effect of ultrasound, that is, the ultrasound propagating in the liquid generates tiny bubbles and explodes inside them, thereby impacting and peeling off the dirt on the surface of the object to achieve the purpose of cleaning. However, the existing ultrasonic cleaning device can only use a single ultrasonic cleaning method to clean the glue roller. The intensity of ultrasonic cleaning is fixed, and the intensity of ultrasonic cleaning cannot be adjusted according to the adaptability of glue rollers of different specifications and types. The cleaning effect is not good, and the glue roller cannot be dried after cleaning, which is poor in practicality. In addition, after the cleaning of the glue roller is completed, it is necessary to judge whether the cleaning is qualified by naked eye observation. This naked eye observation method has a large error, which will affect the judgment of the cleaning effect, and then affect the final cleaning effect of the glue roller. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the present invention aims to provide an ultrasonic cleaning device and method suitable for cleaning a gluing roller of a packaging box, so as to achieve the purpose of improving the cleaning effect and improving the practicability.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: an ultrasonic cleaning device suitable for cleaning the gluing roller of a packaging box, comprising a cleaning table and a control mechanism arranged next to the cleaning table; the cleaning table is provided with a visual detection type mechanism for detecting the type of the gluing roller, an ultrasonic cleaning mechanism for adaptively adjusting the cleaning intensity according to the type of the gluing roller, a hot air drying mechanism for drying the gluing roller and a visual residual glue detection mechanism for detecting the cleaning effect in sequence along the cleaning direction; the cleaning table is provided with a conveying mechanism for conveying the gluing roller of the packaging box to the corresponding cleaning position; the control mechanism is electrically connected to the visual detection type mechanism, the ultrasonic cleaning mechanism, the hot air drying mechanism, the visual residual glue detection mechanism and the conveying mechanism respectively.

[0010] As a further definition of the present invention, the mechanical clamp includes a base fixed on the vertical moving end of the vertical moving linear module, a clamp mounting frame fixed on the base, a driving member fixed on the clamp mounting frame, a driving gear member rotatably connected to the clamp mounting frame and fixedly connected to the power output end of the driving member, a driving clamp hinged on the driving gear member, a first connecting rod hinged between the driving clamp and the clamp mounting frame, a driven gear member rotatably connected to the clamp mounting frame and meshing with the driving gear member, a driven clamp hinged on the driven gear member, and a second connecting rod hinged between the driven gear member and the clamp mounting frame.

[0011] The present invention also provides a method for cleaning a packaging box gluing roller using any one of the above-mentioned ultrasonic cleaning devices suitable for cleaning a packaging box gluing roller, comprising the following steps: Step 1: manually place the glue-coating roller to be cleaned on the platform in the visual inspection mechanism; Step 2: The visual detection type mechanism detects the type of the glue coating roller according to the glue coating roller profile detection method; Step 3: The conveying mechanism conveys the glue-coated roller to the pre-washing tank in the ultrasonic cleaning mechanism and performs preliminary high-pressure washing on the glue-coated roller; Step 4: The conveying mechanism conveys the glue-coated roller to the ultrasonic cleaning tank, and selectively turns on the three-band ultrasonic transducer and the frequency of the three-band ultrasonic transducer at the corresponding position according to the type of the glue-coated roller detected in step 2, so as to achieve different ultrasonic intensities for cleaning of different types of glue-coated rollers; Step 5: The conveying mechanism conveys the glue-coated roller to the rinsing tank and performs a final high-pressure rinse on the glue-coated roller; Step 6: Open the sealing cover of the hot air drying mechanism, the conveying mechanism conveys the glue-coated pressure roller into the hot air drying mechanism and covers the sealing cover of the hot air drying mechanism, and starts the blowing component and the heating box to perform hot air drying on the glue-coated pressure roller; Step seven: Open the sealing cover on the hot air drying mechanism, and the conveying mechanism conveys the glue coating roller to the visual residual glue detection mechanism.

[0012] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: (1) The present invention is provided with a visual type detection mechanism, an ultrasonic cleaning mechanism, a hot air drying mechanism, a visual residual glue detection mechanism and a conveying mechanism. The conveying mechanism can sequentially convey the glue-coated roller to each cleaning process along the cleaning direction. The visual type detection mechanism is used to detect the type of the glue-coated roller. The ultrasonic cleaning mechanism can adaptively adjust the cleaning intensity according to the type of the glue-coated roller. This allows the ultrasonic cleaning mechanism to select a cleaning intensity suitable for glue-coated rollers of different specifications and types, which can effectively improve the cleaning effect. After the cleaning is completed, the hot air drying mechanism can perform hot air drying on the glue-coated roller and the visual residual glue detection mechanism can detect the cleaning effect of the glue-coated roller after drying. The judgment of the cleaning effect is more accurate, which can effectively ensure the final cleaning effect.

The lighting component can provide a light source so that the camera component can take pictures of the glue coating roller at a better angle and a better line of sight, which can effectively improve the accuracy of the visual detection type mechanism in detecting the type of the glue coating roller.

[0014] (3) The ultrasonic cleaning mechanism in the present invention can perform deep cleaning of the glue coating roller through a three-step cleaning process. Specifically, the glue coating roller can first be preliminarily cleaned in a pre-wash tank to wash away the floating dust on the glue coating roller and soften the latex to facilitate subsequent cleaning; then ultrasonic cleaning is performed in an ultrasonic cleaning tank. According to the specifications of the glue coating roller detected by the visual detection mechanism, the cleaning intensity is adaptively adjusted by adjusting the position, number and frequency of the three-band ultrasonic transducers, thereby targetedly cleaning glue coating rollers of different specifications and types, which can effectively improve the cleaning effect; finally, the final cleaning is performed in a rinse tank to further improve the cleaning effect.

[0015] (4) The hot air drying mechanism of the present invention has a simple structure, low manufacturing cost and good drying effect. The blowing component can provide strong wind force, the heating rod can provide sufficient heat, the drying trough and the sealing cover can form a good sealed space, and the wind blown out by the blowing component is converted into hot air through the heating rod and enters the sealed space through the second connecting pipe, and then flows into the blowing component through the first connecting pipe. The hot air continuously enters the sealed space through the heating cycle, and can dry the glue coating roller more quickly and evenly, with good drying effect and high drying efficiency.

[0016] (5) The conveying mechanism of the present invention improves the cleaning efficiency through a mechanized structure, saving the labor intensity of the staff. Specifically, the horizontally moving linear module is used to realize the switching between the cleaning process positions in the visual inspection type mechanism, ultrasonic cleaning mechanism, hot air drying mechanism and visual inspection residual glue mechanism. The vertically moving linear module cooperates with the mechanical clamp to grasp the glue coating roller and place it at the corresponding position.

[0017] In summary, the present invention has a high degree of mechanization, is easy to use and has strong practicality. The present invention can adaptively adjust the intensity of ultrasonic cleaning in the ultrasonic cleaning mechanism according to the specification type of the glue roller detected by the visual detection type mechanism, which can effectively improve the cleaning effect. After the cleaning is completed, the hot air drying mechanism can perform hot air drying on the glue roller and the visual detection residual glue mechanism can detect the cleaning effect of the glue roller after drying, which can effectively ensure the final cleaning effect. The present invention is suitable for use when cleaning the glue roller of the packaging box. BRIEF DESCRIPTION OF THE DRAWINGS
