Description

Technical Field

[0001] The utility model relates to a preheat sealing device, in particular to a preheat sealing device for the end of transparent paper of a cigarette strip packaging machine, belonging to the technical field of cigarette manufacturing. Background Art

[0002] Generally speaking, transparent paper is a layer of transparent packaging material wrapped on the outside of cigarette boxes (packs) and carton boxes (soft strips) to prevent cigarettes from getting damp and the loss of moisture and aroma in cigarettes, as well as to improve the appearance quality of the product.

[0003] At present, during the daily quality inspection of the YB95 transparent paper packaging machine, it was found that the transparent paper at the end of the cigarette strip had some quality defects when folding, lifting and hot-sealing. The lower long side of the transparent paper at the end of the cigarette strip needs to be lifted upward by a lifter after folding, and the upper long side of the end is folded during the lifting process, and finally the packaging is completed by hot-sealing the end with a soldering iron. After the lower long side is folded and then lifted, it is easy to wrinkle and loosen. Occasionally, the lower long side will be rubbed downward during the lifting process, resulting in a quality defect of tailing. At the same time, the next end hot-sealing process will also result in loose sealing and substandard sealing. When these problems occur, the moisture and aroma of the cigarette will be lost, thereby affecting consumers' experience of the taste of the cigarette, and will also affect the appearance quality of the cigarette strip.

[0004] At present, the Chinese utility model patent with announcement number CN204527830U discloses a heat-sealing device for the end of transparent paper in a small box, including a front heat-sealing device and a rear heat-sealing device which are arranged on the left and right sides of the small box conveying channel for movement in opposite directions; the front heat-sealing device and the rear heat-sealing device both include an integrally formed guide plate, a first rectangular heat-sealing plate and a second rectangular heat-sealing plate. When the small box is conveyed to the guide plate position along the small box conveying channel, the front and rear heat-sealing devices clamp the front and rear ends of the transparent paper on the small box for positioning; when the small box is conveyed to the first rectangular heat-sealing plate, the front and rear heat-sealing devices clamp the front and rear ends of the transparent paper on the small box for preheat sealing; when the small box is conveyed to the second rectangular heat-sealing plate, the front and rear heat-sealing devices clamp the front and rear ends of the transparent paper on the small box for heat sealing and shaping. However, the utility model has the following deficiencies: 1. The guide plate does not have the function of preheating and sealing; 2. The heat on the guide plate is transferred by thermal radiation from the rectangular heat sealing plate, so its temperature cannot be guaranteed to be at a constant value. If the temperature is too high, the transparent paper is prone to wrinkling during guiding, which will cause uneven end surface sealing and affect the sealing degree of the small box; 3. The guide plate and the rectangular heat sealing iron are a whole, so when the cigarette pushing plate pushes the cigarette, the guide plate and the rectangular soldering iron are both in the open state, so that the cigarette pack can be smoothly pushed into the heat sealing channel. When the soldering iron is closed, the cigarette pack has been pushed to the rectangular heat sealing plate, so the guide plate does not play the role of squeezing and removing the gas between the transparent paper and the small box body.

[0005] Therefore, the key to solving the above technical problems is to develop a smartly designed, practical and reliable preheating and sealing device for the transparent paper ends of cigarette strips in a packaging machine. Summary of the invention

[0085] More specifically, the fixing frame 42 includes two cross bars arranged opposite to each other and a rotating rod symmetrically rotatingly connected between the two cross bars.

[0086] In the present invention, the fixing frame 42 is in a ladder-shaped structure as a whole.

[0092] A heating rod 52, the heating rod 52 is connected to the other end of the soldering iron body 51;

[0093] The temperature measuring platinum thermal resistor is arranged inside the soldering iron body 51.

[0094] Specifically, Figure 6 As shown, the heating rod 52 is connected to the other end of the soldering iron body 51 in an "eight" shape, and the heating rod 52 passes through the connecting groove 11 and contacts the transparent cigarette paper 8 to complete the heat sealing work.

[0095] In summary, a more specific implementation method of the present invention is:

[0096] Before using the transparent paper end preheat sealing device for a cigarette packing machine of the above-mentioned design structure, it is necessary to manufacture and install it as a backup.

[0097] The specific steps are:

[0098] like Figure 1-Figure 4 As shown, when in use, the detection device 2 is installed on the equipment base 6. When the cigarette pushing plate 7 is at the initial leftmost end, the detection device 2 cannot detect the end of the cigarette pushing plate, the solenoid valve connected to the telescopic device 3 will not be reversed, and the rodless chamber of the telescopic device 3 will not be introduced into the positive compressed air, so the preheat sealing device will not act;

[0099] When the first lifter lifts the cigarette strip 9 with transparent paper to the highest position, the cigarette pushing plate 7 starts to push the cigarette to the right. When the cigarette pushing plate 7 reaches the rightmost end, it will pause, that is, there will be a pause when the cigarette pushing plate 7 pushes the cigarette strip 9 into the second lifter. Then the second lifter will have a lifting action. When the detection device 2 detects that the end of the cigarette pushing plate 7 enters the cigarette pushing plate connecting seat 71, the detection device 2 immediately sends a solenoid valve reversing signal to the telescopic device 3. Compressed air is introduced into the rodless cavity of the telescopic device 3. The compressed air drives the telescopic rod 31 to extend, and then the telescopic rod 31 drives the connecting seat 71. The receiving frame 4 moves forward, and under the movement of the fixed frame 42 of the four-bar mechanism, it drives the heating rod 52 at the end of the electric soldering iron mechanism 5 to pass through the connecting groove 11 pre-opened on the folding plate 1 to pre-seal the front and rear short sides and the lower long side of the transparent paper 8 that has been folded, and the front and rear short sides and the lower long side of the end of the transparent paper 8 are sealed into a whole. In this way, when the second lifter lifts again, the pre-sealed whole will not produce relative sliding or dislocation, which will prevent the looseness and wrinkles of the cigarette strip 9, thereby increasing the flatness and consistency of the hot sealing of the end face of the cigarette strip, reducing the defective rate, and ensuring that the quality of the final product meets the requirements.

[0100] During the above-mentioned use, the signal given by the detection device 2 to the solenoid valve is basically equivalent to a pulse signal, that is, the preheat sealing action of the telescopic device 3 is between 0.5 seconds and 1 second. The specific time depends on the time it takes for the cigarette pushing plate 7 to completely push the cigarette 9 into the second lifter, and the effect of the preheat sealing is also used to determine the pulse time. When the preheat sealing effect is good, the pulse signal will be shorter, and the cylinder will return immediately after the telescopic action. Because the telescopic device 3 is a single-acting cylinder, its return is completed by the force of its own compression spring. If the preheat sealing effect is not good, then readjust the pulse signal to make the cylinder preheat sealing time a little longer until the preheat sealing process requirements can be completed as required.

[0101] Finally, it should be noted that the above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
