Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making equipment, in particular to a pneumatic glue supply system. Background Art

[0002] In addition to paperless filter rods, all tobacco filter rods and cigarette forming processes use forming paper to roll and shape the filter rods or tobacco. During the forming process, adhesive is used to adhere the filter rods or tobacco. Traditionally, the glue supply system for filter rods or cigarette forming typically uses gravity or a gear pump. However, both methods have drawbacks. For example, gravity glue supply systems, due to the high position of the glue cylinder, are not only inconvenient for adding glue, cleaning, adjusting, and maintaining, but also can cause uneven glue supply due to low latex pressure in the nozzle, affecting product quality. Gear pump glue supply systems, on the other hand, are difficult to maintain due to the high precision of part fitting and easy wear. Lubricant contamination of the latex can also affect the quality of the filter rod or cigarette. Utility Model Content

It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0023] Example:

[0024] like Figure 1-2 As shown, this embodiment provides a pneumatic glue supply system, including a glue supply cabinet 1, a glue supply barrel 2, a pneumatic delivery pipeline 3, an air pressure regulating device 4, an air filter device 5, a glue quantity regulating device 6, a glue liquid delivery pipeline 7, a glue gun 8, a glue supply control system 9 and a human-machine interface 10;

[0025] The glue supply barrel 2 is arranged at the lower part of the glue supply cabinet 1. One end of the air pressure delivery pipeline 3 is connected to the top input end of the glue supply barrel 2. The other end of the air pressure delivery pipeline 3 is connected to the output end of the air pressure regulating device 4. The input end of the air pressure regulating device 4 is connected to the output end of the pipeline air filter device 5. The input end of the air filter device 5 is connected to the centralized pressure supply pipeline.

[0026] The top output end of the glue supply barrel 2 is connected to one end of the glue delivery pipeline 7, the other end of the glue delivery pipeline 7 is connected to the input end of the glue quantity adjustment device 6, and the output end of the glue quantity adjustment device 6 is connected to the glue gun 8 through a pipeline;

[0027] The glue supply control system 9 is arranged in the upper part of the glue supply cabinet 1, and the glue supply barrel 2, the air pressure regulating device 4 and the glue quantity regulating device 6 are all electrically connected to the glue supply control system 9 through wires;

[0028] Specifically, the air pressure regulating device 4 regulates the air pressure in the air pressure delivery pipeline 3 and the glue supply barrel 2, and the glue quantity regulating device 6 regulates the glue quantity in the glue delivery pipeline 7 and the glue gun 8, so that the glue quantity applied to the plug paper meets the requirements of the filter rod or cigarette forming process. At the same time, the air filter device 5 separates oil and water from the air pressure delivered by the centralized pressure supply pipeline to ensure that the air pressure is dry and pure.

[0029] The glue supply control system 9 collects the host speed signal through the rotary encoder set at the host cutter disc position, communicates with the host control system, and controls the air pressure regulating device 4 and the glue quantity regulating device 6 to stabilize the air pressure in the glue supply barrel 2 and the output flow of the glue liquid, thereby stabilizing the amount of glue applied to the forming paper. The various parameters of the glue supply system are displayed in real time through the human-machine interface 10, which facilitates the operator to monitor the equipment status in real time.

[0030] In a preferred embodiment of the present invention, further, the glue supply cabinet 1 is welded by a stainless steel frame and a door panel, and four universal wheels are respectively provided at the four corners of the bottom. A drawer-type load-bearing tray is provided at the bottom of the glue supply cabinet 1, and the glue supply barrel 2 is placed on the top of the drawer-type load-bearing tray. The four universal wheels are used to realize the flexible movement of the glue supply cabinet 1, and the hinges are used to realize the free opening and closing of the door. The drawer-type load-bearing tray is provided at the bottom of the glue supply cabinet 1 to realize the front and back movement of the glue supply barrel 2 in the glue supply cabinet 1, which facilitates the opening and closing of the glue supply barrel 2 for adding glue.

[0031] In a preferred embodiment of the present invention, further, the air pressure regulating device 4 includes a proportional regulating valve 401, a safety regulating valve 402, a pressure relief valve 403 and a pressure gauge 404. The proportional regulating valve 401 is arranged on the pipeline between the air filter device 5 and the glue supply barrel 2, and the pressure gauge 404, the safety regulating valve 402 and the pressure relief valve 403 are arranged on the barrel cover of the glue supply barrel 2. The air pressure is adjusted by the air pressure regulating device 4 and displayed through the human-machine interface 10.

[0032] In a preferred embodiment of the present invention, the glue quantity adjustment device 6 further includes a flow meter 601 and a flow regulating valve 602. The flow meter 601 detects the flow in the glue delivery pipeline 7 and displays it through the human-machine interface 10. The flow regulating valve 602 adjusts the glue quantity in real time to stabilize it within the set range.

[0033] In a preferred embodiment of the present invention, further, a glue filter device 201 and a liquid level sensor 202 are provided in the glue supply barrel 2. The glue filter device 201 is connected to the glue gun 8 through the glue delivery pipeline 7 to prevent the glue from clogging the glue gun 8. The liquid level signal in the glue supply barrel 2 is provided to the glue supply control system 9 through the liquid level sensor 202. After the glue supply control system 9 performs data calculation and processing based on the signal, it is displayed through the human-machine interface 10, thereby reminding the operator to add glue in time.

[0034] The working principle of this pneumatic glue supply system is as follows: air pressure is delivered from a centralized pressure supply pipeline, passes through an air filter device 5 for oil-water separation, and is then delivered to a proportional control valve 401 via a pneumatic delivery pipeline 3. The proportional control valve 401 adjusts the pressure of the pneumatic delivery pipeline 3 according to the pipeline pressure value set by the glue supply control system 9, and then the pneumatic liquid enters the glue supply barrel 2. At the same time, a pressure gauge 404 on the upper cover of the glue supply barrel 2 displays the pressure value. The glue in the glue supply barrel 2 is squeezed by the air pressure and discharged through the glue delivery pipeline 7.

[0035] When outputting from the glue supply barrel 2, the glue filtering device 201 in the glue supply barrel 2 performs secondary filtration on the glue and then outputs it to the position of the flow regulating valve 602 through the glue delivery pipeline 7. The flow regulating valve 602 adjusts the glue flow rate according to the signal calculated by the host operation speed signal collected by the glue supply control system 9 and then enters the glue gun 8. The glue flow rate is displayed by the flow meter 601. When the glue in the glue supply barrel 2 is lower than the set liquid level value, the liquid level sensor 202 in the glue supply barrel 2 provides a signal to the glue supply control system 9. The glue supply control system 9 displays the air pressure, glue flow rate and the amount of glue in the glue supply barrel 2 through the human-machine interface 10, which is convenient for real-time viewing of the operation status of the pneumatic glue supply system.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
