Description

Technical Field

[0001] This application relates to the field of cigarette equipment technology, specifically to a glue supply device for a packaging machine. Background Technology

[0002] During operation, the carton paper gluing device needs to replenish latex at appropriate temperature and humidity based on feedback signals from the glue tank level detector. During this period, due to the glue supply tank not being sealed properly in the previous working step, the glue viscosity increases and dries, the latex oxidizes and deteriorates, or impurities and dust are mixed in, which in turn leads to abnormal wear of the gluing wheel, resulting in the carton paper not being firmly adhered. At the same time, the inner wall of the glue supply tank is severely sludged, and the volume decreases, leading to frequent glue additions and increasing the labor intensity of the machine operators. Utility Model Content

[0003] The purpose of this application is to provide a glue supply device for a packaging machine, so as to solve the defects of the prior art where the glue supply tank is not sealed properly and the moisture content inside the tank cannot be well guaranteed, which affects the quality of the glue and causes serious dirt accumulation.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] This application discloses a glue supply device for a packaging machine, which includes...

[0006] A glue supply tank is provided, and a box cover is installed on the glue supply tank; a first cavity and a second cavity are provided between the glue supply tank and the box cover, and an ultrasonic atomizer is installed in the second cavity for humidifying the first cavity;

[0007] A pneumatic diaphragm pump is used to discharge glue from the first cavity.

[0008] In a further embodiment of this application, the glue supply tank is provided with a partition, which, together with the glue supply tank and the box cover, forms the first cavity and the second cavity, and the bottoms of the first cavity and the second cavity are not interconnected.

[0009] In a further embodiment, the volume of the first cavity is larger than the volume of the second cavity.

[0010] In a further embodiment of this application, a convex surface is integrally formed on one side of the box cover, and the box cover closes the glue supply tank, so that the convex surface presses against the inner wall of the glue supply tank.

[0011] In a further embodiment of this application, the pneumatic diaphragm pump is fixed on the housing cover, the first cavity is connected to the input end of the pneumatic diaphragm pump via a suction pipe, and the output end of the pneumatic diaphragm pump is equipped with a dispensing pipe.

[0012] In a further embodiment of this application, a silencer is fixed on the pneumatic diaphragm pump.

[0013] In a further embodiment of this application, the glue supply tank is also provided with a glue injection port and a waste glue discharge port.

[0014] A further embodiment of this application includes a mounting base, wherein the glue supply bucket is fixed to the mounting base.

[0015] The beneficial effects of this application are as follows:

[0016] In this application, the glue supply tank is equipped with a first chamber and a second chamber, changing the original glue supply mode of the glue dispensing valve. During use, the two chambers are filled with packaging glue and purified water, respectively. After the pneumatic diaphragm pump completes the glue dispensing action, the ultrasonic atomizer works to humidify the inside of the glue tank (first chamber), ensuring that the packaging glue has a suitable humidity, preventing excessive accumulation of dirt, which would cause a significant reduction in the glue capacity of the glue tank, thereby avoiding frequent glue addition. In addition, the packaging glue with suitable humidity, coupled with the closed environment, prevents the entry of impurities and ensures the quality of the glue.

[0017] The box has a raised surface that fits tightly against the glue supply tank during installation, providing a strong sealing effect and reducing the possibility of dust, dirt, and other impurities entering the packaging glue. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0024] like Figure 1 and Figure 2As shown, this embodiment discloses a glue supply device for a packaging machine, which includes a glue supply tank 2 and a pneumatic diaphragm pump 7. The pneumatic diaphragm pump 7 is connected to the glue supply tank 2. A box cover 10 is installed on the glue supply tank 2. A first cavity 101 and a second cavity 102 are provided between the glue supply tank 2 and the box cover 10. An ultrasonic atomizer 4 is installed in the second cavity 102 for humidifying the first cavity 101. The pneumatic diaphragm pump 7 is used to discharge the glue in the first cavity 101.

[0025] In use, the first cavity 101 is filled with packaging adhesive, and the second cavity is filled with purified water. The pneumatic diaphragm pump 7 is started to extract the packaging adhesive from the first cavity 101 for use in downstream processes. The ultrasonic atomizer 4 is started intermittently to atomize the purified water in the second cavity 102 to ensure the humidity of the packaging adhesive. In actual production, the ultrasonic atomizer 4 is controlled by a time relay to achieve a constant humidity of the adhesive liquid inside the adhesive tank.

[0026] In this embodiment, the glue supply tank 2 is equipped with a partition. The partition, the glue supply tank 2, and the box cover 10 form a first cavity 101 and a second cavity 102. The bottoms of the first cavity 101 and the second cavity 102 are not interconnected. When the box cover 10 covers the top opening of the glue supply tank 2, space needs to be left for gas communication between the first cavity 101 and the second cavity 102. The partition can be integrally molded with the glue supply tank 2, which speeds up the manufacturing process and ensures the sealing between the partition and the glue supply tank 2, preventing direct communication between the packaging glue and the purified water. Considering the usage requirements of the packaging glue and purified water, the volume of the first cavity 101 is larger than the volume of the second cavity 102. Here, the volume of the first cavity 101 is designed to be about three times the volume of the second cavity 102 to meet the usage requirements.

[0027] In a further embodiment, a convex surface is integrally formed on one side of the box cover 10. An appropriate amount of sealing ribs can be fixed on the outer side of the convex surface to ensure the overall sealing of the glue supply tank 2 while avoiding direct friction between the glue supply tank 2 and the box cover 10. The box cover 10 closes the glue supply tank 2, so that the convex surface presses against the inner wall of the glue supply tank 2, forming a relatively sealed space inside the glue supply tank 2 to prevent dust and other small particulate impurities from entering the glue supply tank 2 and to ensure the quality of the packaging glue.

[0028] The pneumatic diaphragm pump 7 in the device is fixed to the housing cover 10 by bolts. The first chamber 101 is connected to the input port of the pneumatic diaphragm pump 7 by a suction pipe 9. The output end of the pneumatic diaphragm pump 7 is equipped with a glue discharge pipe 8. The glue discharge pipe 8 is made of a relatively soft rubber tube. Considering that the equipment may generate a lot of noise when it is working, a silencer 5 is fixed on the pneumatic diaphragm pump 7. The silencer 5 is installed on one side of the air inlet 6 of the pneumatic diaphragm pump 7. In actual production, one end of the glue discharge pipe on the pneumatic diaphragm pump 7 is connected to the glue cylinder. A detector is set in the glue cylinder to detect the glue level. When the glue level is insufficient, the pneumatic diaphragm pump 7 is started to supply glue to the glue cylinder.

[0029] The device improves the sealing design of the box and lid to enhance its sealing performance. At the same time, an ultrasonic atomizing device 4 is installed inside the glue supply tank 2 to ensure the stable moisture content of the latex in the tank, reduce the possibility of deterioration and contamination, and thus improve the equipment's ability to guarantee product quality.

[0030] In this embodiment, the glue supply tank 2 is also provided with a glue injection port 11 and a waste glue discharge port 3; the glue injection port 11 is a sealed quick connector, which can be connected to the glue adding vehicle for quick glue addition.

[0031] In some embodiments, the designers have also incorporated a human-centered design into the box cover 10, with a handle on the side of the box cover 10 facing away from the convex surface. By adopting an ergonomic shape and size, hand fatigue during use is reduced. At the same time, the pouring method for dispensing glue is replaced with a glue pump injection method, which significantly reduces safety risks and the rate of labor errors.

[0032] In practical use;

[0033] The glue supply tank 2 is fixed on the mounting base 1, and then the mounting base 1 is fixed on the designated frame, changing the original glue supply mode of the glue injection valve. The first chamber 101 is used to store packaging glue, specifically for the packaging glue required by the CT glue cylinder. The second chamber 102 stores purified water. When the pneumatic diaphragm pump 7 receives the signal from the detector in the CT glue cylinder, it starts or stops, completing one glue supply and stop action. The ultrasonic atomizer 4 starts after receiving the instruction, replenishing water inside the glue supply tank 2 to prevent the packaging glue inside the tank from drying out. This ensures stable glue quality and reliable humidity for downstream processes. When the glue supply tank 2 needs to be filled with packaging glue, it is injected from the side joint, avoiding manual operation of opening the box cover 10 and causing water loss inside the tank. At the same time, the horizontal installation of the glue supply tank 2 facilitates cleaning and maintenance by the staff. In practical applications, this project will promote technological innovation in the packaging industry, introduce advanced design concepts and materials, enhance the technical content and competitiveness of products, promote the intelligent transformation of the industry, and set an advanced model for the industry. It acts as a great catalyst in motivating employees to improve their awareness and ability to innovate.
