Description

TECHNICAL FIELD

[0001] The utility model relates to a gluing device, especially a ballpoint gluing device of a cigarette making machine. BACKGROUND

[0002] The main task of the cigarette making machine is to complete the rolling of the tobacco rod, which puts the tobacco rod delivered by the feeding and rolling machine into the cigarette paper delivered by the paper feeding and printing system (as shown in Figure 3 ), and then forms a tobacco rod with a circumferential size after the two edges of the cigarette paper are bonded together.

[0003] The main transmission system of the cigarette making machine drives the belt pulley, which drives the belt 25 to send the cigarette paper 23 into the suction belt pulley of the suction belt of the suction and forming system of the feeding and rolling machine of the cigarette gun, and the tobacco 22 adsorbed on the suction belt reaches the front end of the cigarette gun assembly, and the suction force disappears, and the tobacco 22 falls on the moving cigarette paper 23 under the action of the tobacco shoveling knife, and moves forward under the action of the belt 25. When passing through the cigarette tongue, the tobacco is compressed and starts to gradually form; when entering the small pressure plate 17 of the cigarette gun, the tobacco 22 is further compressed and formed, and the tobacco 22 is formed between the bottom plate 26 of the cigarette gun, the small pressure plate 17 and the outer edge 24.

[0004] The gluing device of the cigarette making machine is used to continuously apply uniform glue lines to the joint of the cigarette paper during the rolling and forming process, so that the joint is bonded. The gluing device applies glue to the raised edge of the cigarette paper, and then enters the large pressure plate for the final forming. When passing through the soldering iron device, the glue at the joint is dried, and the tobacco rod is formed. The rolling and forming is a key link in the production of cigarettes, which determines the appearance quality of the cigarette and the stability of the cigarette circumference. During the rolling and forming process, it is necessary to ensure that the surface of the cigarette is clean and tidy, and there is no tobacco or tobacco dust mixed in the joint.

[0005] The existing gluing device mainly consists of a nozzle rod 31, a rotating cylinder, a glue bucket, a glue pump and a toothed belt 6. During work, the glue flows from the glue bucket to the inlet of the glue pump, and the glue pump pressurizes the glue into the nozzle 31 (as shown in Figure 4 ).

[0006] The existing gluing device has the following shortcomings:

[0007] 1. The existing nozzle is installed in the middle of the small pressure plate 17. After the cigarette paper is coated with glue, the cigarette paper needs to run a long distance, and then the edge of the cigarette paper coated with glue is combined with the other edge under the action of the large pressure plate 19. In this process, the flying tobacco and tobacco dust are easily attached to the glue, forming a tobacco joint with tobacco dust, which causes quality defects.

[0008] 2. The existing nozzle rod 31 applies adhesive to the raised edges of the cigarette paper. Because the cigarette paper 23 is relatively soft and there is no support behind the paper during the adhesive application process, discontinuous adhesive application is likely to occur, resulting in quality defects such as cigarette tip breakage.

[0009] 3. Existing nozzle devices have complex structures, such as... Figure 4 As shown, the rear end of the nozzle device is equipped with an adjusting screw 28, an adjusting rod 29, and a locking element 30. The nozzle needle is mounted at the front end of the nozzle rod. The nozzle contains many O-rings, springs, and other components, which require regular disassembly, cleaning, and lubrication, making maintenance difficult. Summary of the Invention

A notch is opened at the lower end of the cylinder. The piston is installed in the cylinder above the notch. The key is fixed on the inner circumference of the cylinder above the notch. The piston has a groove on its upper side, within which the key moves up and down. A spring is mounted on the outer circumference of the piston, with its upper end pressing against the upper end of the piston and its lower end pressing against the key. One end of the support plate extends into the notch and is fixed to the lower end of the piston by a short screw. The other end of the support plate is equipped with a nozzle, the lower end of which passes through and is fixed to the other end of the support plate. A ball is mounted on the lower end of the nozzle, and the upper end of the nozzle has a glue inlet. A locking nut and an adjusting bolt are also mounted on the support plate extending out of the notch. The lower end of the adjusting bolt passes through the support plate, and the locking nut is mounted on the adjusting bolt at the upper end of the support plate.

[0012] The present invention relates to a ball-type gluing device for a cigarette machine, wherein the long screw passes through the upper cover and the cylinder to fix the gluing device on the frame.

[0029] The operation steps of the ball type glue applying device of the cigarette making machine are as follows:

[0030] 1. When producing, the cigarette paper exerts certain pressure on the ball 8, pushes the ball upward, makes the glue flow out from the gap between the ball and the nozzle, and coats the glue on the cigarette paper along the rotation of the ball; when stopping, the ball 8 seals the nozzle under the pressure of the glue, so that the glue cannot flow out.

[0031] 2. The nozzle 6 is fixed on the glue applying device through the short screw 11, can be quickly disassembled, and is cleaned or replaced.

[0032] 3. A cylinder drives the nozzle 6. When the equipment starts, the solenoid valve controls the compressed air to enter the cylinder 1. Under the action of the compressed air, the piston 4 in the cylinder 1 drives the nozzle 6 to move downward to the working position and lightly presses it on the cigarette paper to start applying glue. When the equipment stops, under the action of the return spring 12, the nozzle 6 moves upward away from the cigarette paper and stops applying glue.

[0033] 4. Nozzle 6 is installed vertically downward between the outlet of the small pressure plate and the inlet of the large pressure plate. After applying glue to the lower edge of the cigarette paper, the upper edge of the paper is quickly pressed down by the large pressure plate to stick it to the glue, thus preventing tobacco shreds and tobacco dust from entering the overlap.

[0034] like Figure 5 As shown, the gluing state of the ball-type gluing device for cigarette machines of this utility model is different from that of the gluing state of the device. Figure 4 The adhesive application state shown in the prior art has significant advantages.

[0035] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
