Description

Technical Field

[0001] This utility model relates to the field of adhesive supply technology, specifically to an adhesive supply device for cigarette packaging. Background Technology

[0002] In the packaging and forming process of cigarette cartons, glue needs to be applied to the individual carton sheets during transportation. This is done by spraying glue onto specific locations on the carton sheets. The system consists of a glue spraying system and a glue supply system, connected by a glue hose. Because the glue has a certain viscosity, it is sprayed out using compressed air from a glue supply tank. However, in existing technology, compressed air acts on the glue supply tank, which has a large volume. This requires more compressed air to reach the glue spraying system, making the initial spraying process slow. Furthermore, when there is insufficient glue in the supply tank, compression makes it difficult to spray out the small amount of glue. To overcome this technical problem, this invention provides a glue supply device for cigarette packaging. Utility Model Content

[0020] Please see Figure 1 This utility model provides a glue supply device for cigarette packaging, including a glue supply cylinder 1. The glue supply cylinder 1 is made of stainless steel and has a conical bottom. A fixing cover 2 is provided at the upper port of the glue supply cylinder 1. The fixing cover 2 can be connected to the upper port of the glue supply cylinder 1 by screws. A pressing cavity 1a is integrally provided at the bottom of the glue supply cylinder 1. More specifically, the pressing cavity 1a is located at the bottom of the conical part of the glue supply cylinder 1. The bottom surface of the pressing cavity 1a is provided with glue passage holes 1b. A glue pressure detection box 16 is provided at the bottom of the pressing cavity 1a so that the glue in the glue supply cylinder 1 can enter the glue pressure detection box 16 through the glue passage holes 1b.

[0021] Specifically, the volume of the glue pressure testing box 16 is the same as the volume of the glue pressing chamber 1a, so that the glue pressure testing box 16 can accommodate the glue in the region of the glue pressing chamber 1a. A spiral heating coil 18 is provided on the outside of the compressed air inlet pipe 19 of the glue pressure testing box 16 to heat the glue and increase its fluidity. It should be noted that the spiral heating coil 18 needs to be used according to the characteristics of the glue. A protective sleeve 17 is provided on the outside of the spiral heating coil 18. Preferably, the protective sleeve 17 is a heat insulation material and is fitted on the compressed air inlet pipe 19.

[0022] The fixed cover 2 is provided with a retractable lifting rod 12, which extends into the glue supply cylinder 1 and is provided with a glue pressing piston 13 at the bottom of the lifting rod 12. The glue pressing piston 13 is located directly above the glue pressing chamber 1a, and the size of the glue pressing piston 13 matches the inner wall size of the glue pressing chamber 1a.

[0023] Specifically, a cylinder 4 is provided on the top of the fixed cover 2. The push-out end of the cylinder 4 passes through the fixed cover 2 and is connected to the lifting rod 12. When the cylinder 4 is fully pushed out, the pressing piston 13 contacts the bottom surface of the pressing chamber 1a, thereby pressing all the glue in the pressing chamber 1a into the glue pressure testing box 16. When the cylinder 4 is in the initial state, there is a gap between the pressing piston 13 and the upper port of the pressing chamber 1a so that the glue can flow into the pressing chamber 1a.

[0024] Furthermore, a fixed sleeve 11 is fixedly installed on the bottom surface of the fixed cover 2, and the lifting rod 12 passes through the fixed sleeve 11. Bearings 22 are provided at the upper and lower ends of the outer side of the fixed sleeve 11, and a rotating sleeve 10 is sleeved on the outer ring of the bearings 22, so that the rotating sleeve 10 can rotate freely. A scraper rod 15 is provided at the bottom of the rotating sleeve 10. The scraper rod 15 contacts the conical surface of the glue supply cylinder 1, thereby scraping off the glue on the inner wall of the glue supply cylinder 1.

[0025] To further drive the rotation of the scraper rod 15, the upper end of the rotating sleeve 10 is provided with a driven gear ring 9, and a motor 3 is provided on the fixed cover 2. The output end of the motor 3 is provided with a driving gear 8, which meshes with the driven gear ring 9. The bottom surface of the fixed cover 2 is provided with a gear cover 7 for covering the driving gear 8 and the driven gear ring 9. The fixed cover 2 is also provided with a feed port 6, and a movable cover 5 is rotatably provided on the feed port 6. The movable cover 5 is hinged to one side of the feed port 6, so that glue can be added to the glue supply cylinder 1 through the feed port 6.

[0026] The glue supply cylinder 1 is detachably equipped with a glue filter plate 14, and the rotating sleeve 10 passes through the center of the glue filter plate 14 to facilitate the filtration of the added glue.

[0027] The glue pressure testing chamber 16 is connected to a compressed air inlet pipe 19 and a glue discharge pipe 21 on the outside. The compressed air inlet pipe 19 is connected to a compressed air source, and the glue discharge pipe 21 can be connected to a glue spraying system through a glue hose. A glue pressure testing sensor 20 is also provided on the side wall of the glue pressure testing chamber 16. The glue pressure testing sensor 20 can be one or more combinations of a water pressure sensor, a liquid level sensor, and a temperature sensor.

[0028] The working process of this utility model is as follows: Adhesive is poured into the glue supply cylinder 1 through the inlet 6. The adhesive is filtered through the filter plate 14 and flows to the bottom of the glue supply cylinder 1. Compressed air is introduced through the pipe 19 and connected to a compressed air source. The glue discharge pipe 21 is connected to the glue spraying system. When glue spraying is required, the cylinder 4 is opened, and the glue pressing piston 13 moves downward to press the adhesive in the glue pressing chamber 1a into the glue pressure detection box 16. The adhesive in the glue pressure detection box 16 is then transported to the glue spraying system by compressed air and sprayed out. When the adhesive level in the glue pressure detection box 16 reaches a certain value... When a certain value is reached, cylinder 4 is reset and pushed out again. When the amount of glue remaining in glue supply cylinder 1 is small, motor 3 is turned on, causing rotating sleeve 10 to drive scraper rod 15 to rotate and scrape the glue on the inner wall of glue supply cylinder 1 so that a small amount of glue is discharged into the pressing chamber 1a as much as possible. Then, the pressing piston 13 presses it into glue pressure test box 16. Since the volume of glue pressure test box 16 is much smaller than that of glue supply cylinder 1, the small amount of glue can be concentrated in glue pressure test box 16 so that it can be sprayed out by compressed air.

[0029] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
