Description

Technical Field

[0001] The invention relates to the technical field of coagulated adhesive scale removal, and in particular to a multifunctional ultrasonic vibration adhesive removal device. Background Art

[0002] At present, long-term operation of packaging machines in cigarette enterprises will cause glue scale to condense, which directly affects product quality and production efficiency. For example, glue scale condensation at the scraper plate of the glue cylinder of the small box packaging machine will cause uneven scraping of glue, resulting in quality accidents of small box opening. In order to prevent defective products from entering the market, workers need to stop the machine to clean glue after discovering quality problems. However, the scraper plate has a complex structure and a small space. It takes a long time and is difficult for workers to clean glue scale. Incomplete cleaning of glue scale will bury hidden dangers for the next small box opening quality accident. Workers need to thoroughly clean the glue cylinder when ending production on weekends and at the end of the month. However, the glue cylinder is heavy, has many parts, and a complex structure. The glue scale is severely bonded and difficult to clean. Bumps and cuts are easily caused by force during the cleaning process. These factors make it difficult and time-consuming for workers to clean the glue cylinder.

[0003] At present, there are no invented tools and methods for cleaning the glue scale in the glue cylinder in the cigarette industry. If a tool can be invented to assist in manually cleaning the glue scale, it will help reduce the labor intensity of workers and improve work efficiency. Summary of the invention

[0004] In order to solve the problems in the prior art, the present invention provides a multifunctional ultrasonic vibration glue cleaning device, which removes coagulated glue scale by high-frequency vibration of a working head, thereby achieving rapid and thorough removal of coagulated glue scale.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a multifunctional ultrasonic vibration glue cleaning device, including an ultrasonic vibrator for generating sound wave vibrations, the ultrasonic vibrator is composed of an ultrasonic transducer and an ultrasonic amplitude transformer, and a working head for glue cleaning is detachably fixedly installed at the end of the ultrasonic amplitude transformer; the ultrasonic amplitude transformer is composed of a conical section connected to the ultrasonic transducer and a cylindrical section connected to the working head, which are smoothly connected, and the diameter of the ultrasonic amplitude transformer gradually decreases from the conical section to the cylindrical section; an outer spiral groove is provided on the outer circumference of the cylindrical section of the ultrasonic amplitude transformer.

[0006] The end of the working head is a scraper, a scraper or a ball head.

[0007] The ultrasonic horn is detachably fixedly connected to the ultrasonic transducer via stud bolts.

[0008] The working head is provided with a single-head bolt integrally fixedly connected thereto, and the working head is detachably fixedly mounted on the corresponding end of the ultrasonic horn through the single-head bolt.

[0009] The helix angle of the outer spiral groove is 30 degrees.

[0010] The ultrasonic vibrator is connected with a handheld part.

[0011] The ultrasonic vibrator is electrically connected to an external ultrasonic generator.

[0012] The ultrasonic transducer includes a transducer body and a plurality of piezoelectric ceramic sheets sleeved on the transducer body, conductive rings are respectively sandwiched between the piezoelectric ceramic sheets and between the piezoelectric ceramic sheets and the transducer body, and an end cover is provided at the end of the transducer body, and the end cover presses the piezoelectric ceramic sheets by means of a pre-tightening bolt and maintains an appropriate pre-tightening force.

[0013] The beneficial effects of the present invention are:

[0014] The multifunctional ultrasonic vibration glue cleaning device in the present invention utilizes the piezoelectric effect to realize the conversion of electrical energy and mechanical energy (sound wave vibration). The ultrasonic generator emits a high-frequency voltage to make the ultrasonic transducer generate high-frequency telescopic vibration. The ultrasonic amplitude transformer changes (amplifies) the vibration amplitude of the ultrasonic transducer and transmits it to the working head. Then, the condensed glue scale is removed by the high-frequency vibration of the working head. Among them, the function of the external spiral groove on the ultrasonic amplitude transformer is to decompose the transmitted longitudinal vibration into longitudinal vibration and torsional vibration, so that the working head produces a composite vibration effect of longitudinal vibration and torsional vibration.

[0015] The invention has a simple structure and is easy to use. The coagulated adhesive scale is removed by high-frequency vibration of the working head, thereby reducing the labor intensity of workers.

[0016] The ultrasonic horn of the present invention is composed of a cone section connected to the ultrasonic transducer and a cylindrical section connected to the working head which are smoothly connected, and the diameter of the ultrasonic horn gradually decreases from the cone section to the cylindrical section. For areas restricted by space, the multifunctional ultrasonic vibration glue cleaning device can reach the area and vibrate the glue scale off, thereby reducing the difficulty of workers in glue cleaning.

[0017] The working head is provided with a single-head bolt integrally connected thereto, and the working head is detachably fixedly mounted on the corresponding end of the ultrasonic amplitude transformer through the single-head bolt. Through this design, the working head of the multifunctional ultrasonic vibration glue cleaning device can be quickly replaced, which is convenient for selecting suitable glue cleaning tools according to different situations and for sharpening and reuse of the working head after wear.

A working head 4 for glue cleaning is detachably fixedly mounted on the end of the ultrasonic horn 2. In this embodiment, the working head 4 is a ball head, which can also be a working device such as a scraper or a scraper. The working head 4 can be quickly replaced according to the use requirements, so that a device can have multiple functions.

[0023] The ultrasonic transducer includes a transducer body 9 and a plurality of piezoelectric ceramic sheets 8 sleeved on the transducer body 9, conductive rings (marked in the drawings) are sandwiched between the piezoelectric ceramic sheets 8 and between the piezoelectric ceramic sheets 8 and the transducer body 9, and an end cap 1 is provided at the end of the transducer body 9, and the end cap 1 presses the piezoelectric ceramic sheets 8 and maintains an appropriate pre-tightening force through a pre-tightening bolt 7. The ultrasonic transducer is a prior art, and its installation position and working principle are not described in detail.

[0024] The ultrasonic horn 2 is composed of a cone section 21 connected to the ultrasonic transducer and a cylindrical section 22 connected to the working head 4, and the diameter of the ultrasonic horn 2 gradually decreases from the cone section 21 to the cylindrical section 22. This design is aimed at the parts with limited space, and the ultrasonic horn 2 and the working head 4 can reach the parts and vibrate the glue scale off, reducing the difficulty of workers to clean the glue.

[0025] The outer circumference of the cylindrical section 22 of the ultrasonic horn 2 is provided with an outer spiral groove 3 with a spiral angle of 30 degrees, which can cooperate to realize the longitudinal and torsional composite vibration of the working head, so as to facilitate the removal of condensed adhesive scale in small holes and gaps. In practical applications, the length of the cylindrical section should be set to facilitate both the processing of the outer spiral groove 3 and the extension of the working head 4 into a deeper space to remove adhesive scale.

[0026] In this embodiment, the working head 4 is provided with a single-head bolt 11 integrally fixed thereto, and the working head 4 is detachably fixedly mounted on the corresponding end of the ultrasonic amplitude transformer 2 by means of the single-head bolt 11.

The ultrasonic generator 6 emits a high-frequency voltage to make the ultrasonic transducer generate high-frequency telescopic vibration (frequency greater than 20K Hz).
