Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette rod packaging, in particular to a sealing device for a filling machine. BACKGROUND

[0002] Low-temperature non-combustion cigarettes (commonly known as "cigarette cartridges") are new tobacco products that are currently popular in Southeast Asian countries. Unlike electronic cigarettes, which are inhaled after being atomized by electronic devices, low-temperature non-combustion cigarettes are inhaled after being smoked by directly heating tobacco raw materials with electronic devices. Since the heating temperature can be accurately controlled at about 300°C, the smoke composition is relatively stable, and the harmful substances are relatively less harmful, so it is favored by smokers. In the production of low-temperature non-combustion cigarettes, first, a composite machine is used to make a composite filter rod from a fiber rod, a cooling rod, and an empty tube rod. Then, a filling machine is used to fill low-temperature non-combustion tobacco particles into the cavities at both ends of the composite filter rod. After sealing, the rod is wrapped with water-based paper, and then cut into two to obtain finished cigarettes. Because the glue-coated surface at the sealing position of the composite filter rod is relatively narrow and the amount of glue is limited, the sealing is often not firm, resulting in too many unqualified products and affecting the overall output of the production line.

[0022] The sealing device for the filling machine provided by the present application comprises a rack, the rack is provided with

[0023] a paper feeding unit for continuously feeding the sealing paper;

[0024] a positioning and adhering unit for positioning the sealing paper and adhering it on the filling port of the cigarette rod, the positioning and adhering unit has a lifting plate, the lifting plate is provided with a positioning component and a pressing solid component;

[0025] a cutting unit for cutting the sealing paper adhered on the filling port of the cigarette rod.

[0026] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, the embodiments are based on the technical scheme of the present application and give a detailed implementation manner, but the protection scope of the present application is not limited to the following embodiments.

[0027] As shown in Figure 1 , 2 , the paper supply unit includes a paper supply roller 21 and a paper collection roller 22 mounted on the frame 1, the sealing paper Z is output from the paper supply roller 21, cut and adhered when passing above the tobacco rod filling port, and then sent to the paper collection roller 22 for recycling. A plurality of adjusting rollers 23 (including a paper pressing roller) are arranged between the paper supply roller 21 and the paper collection roller 22, so that the sealing paper can basically maintain a horizontal state when passing above the tobacco rod filling port.

[0028] The lifting plate in the positioning and adhering unit is a horizontal plate 32 driven by a lifting cylinder 31, and the positioning assembly mounted thereon includes a positioning block 33 and a clamping shaft 34. The positioning block 33 is mounted on the bottom of the lifting plate 32 on both sides, and the distance between the two positioning blocks 33 is matched with the width of the sealing paper Z, which can effectively prevent the paper from deviating; the clamping shaft 34 is a columnar body with a sealing paper passage 35 in the middle, which is mounted at the paper outlet end of the lifting plate 32 and located on the front and rear sides of the tobacco rod to be sealed. In this embodiment, there are two clamping shafts 34, and the number of clamping shafts 34 can be increased according to actual working conditions. A pressing assembly is also mounted on the top surface of the lifting plate, which includes a push-pull cylinder 36 and a pressing plate 37. The push-pull cylinder 36 is arranged near the paper inlet end of the horizontal plate 32, and the cylinder body is hingedly connected with the horizontal plate 32, and the piston rod is hingedly connected with the middle part of the pressing plate 37. The pressing plate 37 is an L-shaped structure, arranged near the paper outlet end of the horizontal plate 32, hingedly connected with the horizontal plate 32 at one end, and extended to the position between the clamping shafts 34 corresponding to the tobacco rod filling port. When the piston rod of the push-pull cylinder 36 is retracted, the pressing plate 37 can be pulled up and rotated backward to leave the area above the tobacco rod filling port, facilitating the cutting unit to cut the sealing paper.

[0029] The cutting unit adopts a laser cutter 4, which is usually mounted on the frame 1 and used for circular cutting of the sealing paper Z adhered on the tobacco rod filling port.

[0030] In order to prevent the tobacco rod Y from moving during the sealing operation, the application also provides a reinforcing unit, which includes a push cylinder 51 mounted on the frame 1, a push plate 52 mounted on the push cylinder 51 and opposite to the side wall of the tobacco rod, and a buffer pad (such as a sponge block) mounted on the push plate 52 and abutting against the side wall of the tobacco rod.

[0031] The frame 1 is also provided with a lifting type tobacco rod supporting frame 6, which is provided with a plurality of tobacco rod supporting columns 61 for supporting the tobacco rod Z.

[0032] In operation, firstly, the sealing paper Z is installed in place, and after being drawn out from the paper feeding roller 21, positioned by the horizontal plate 32 and the clamping shaft 34, and returned to the paper collecting roller 22; then, the cigarette holder 6 is started, and the cigarette rod Z thereon is adjusted to a proper height; then, the lifting cylinder 31 is started, and the horizontal plate 32 and the components thereon are simultaneously lowered to a position, and the sealing paper Z is in micro-contact with the glue liquid coated on the filling opening of the cigarette rod Z; then, the push-pull cylinder 36 is started, and the piston rod thereof is extended, and the pressing plate 37 connected therewith pushes the sealing paper Z downwards, so that the sealing paper Z is in close contact with the glue liquid; after a certain time, the piston rod of the push-pull cylinder 36 is retracted, and the pressing plate 37 is turned back to leave the area above the filling opening of the cigarette rod Z; at this time, the laser cutter 4 is started, and the sealing paper Z is cut according to the contour of the filling opening of each cigarette rod Z, and one sealing operation is completed. After that, the paper feeding roller 21 and the paper collecting roller 22 are started, and the next batch of cigarette rods Z reaches the sealing position, and the above operation is repeated, and the next sealing operation is performed.
