Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a cigarette making machine. Background Art

[0002] Cigarette-making machine production equipment primarily consists of three parts: the feeder-stripper, the paper-forming machine, and the filter-rod assembler. The feeder-stripper provides the paper-forming machine with a continuous supply of tobacco bundles that meet process requirements. The paper-forming machine combines the tobacco bundles with cigarette paper according to process requirements to form a continuous, long tobacco rod. The tobacco rod cutting and conveying devices transport the tobacco rods to the filter-rod assembler. The filter-rod assembler transforms the tobacco rods, filter rods, and tipping paper into qualified cigarettes that meet process quality requirements. The feeder-stripper is equipped with a suction mechanism, and the paper-forming machine is equipped with a glue gun for applying glue to the cigarette paper in the tobacco rods.

[0003] The cigarette paper forming machine is also equipped with a pressure plate, which is equipped with a conveyor channel for the cigarette rods to pass through and a paper edge height detector. The paper edge height detector is mainly used to detect the height of the cigarette paper edge on the cigarette rods, ensuring that the paper edge height is within a set range, thereby improving product quality. Generally, the paper edge height detector is a photoelectric sensor, including a transmitter and a receiver, which are respectively located on either side of the conveyor channel. The transmitter is used to emit a detection beam. When the detection beam is successfully received by the receiver, it indicates that the height of the cigarette paper edge is within the set range. When the height of the cigarette paper edge is too high, the cigarette paper blocks the detection beam, causing the detection beam to be unable to be received by the receiver. At this time, the paper edge height detector will send a signal to the control system of the cigarette paper forming machine. The control system adjusts the height of the cigarette paper by controlling the relevant mechanisms to reduce the paper edge height to within the set range.

[0004] In actual applications, the false detection rate of the paper edge height detector is extremely high. When the paper edge height detector makes a false detection, it sends an error signal to the control system. The control system adjusts the height of the cigarette paper edge based on the error information, which ultimately leads to a lower pass rate for finished cigarettes. Utility Model Content

[0005] The purpose of the present invention is to solve the problem that the quality of finished cigarettes is reduced due to false detection of the existing paper edge height detector. The present invention provides a cigarette making machine that can avoid false detection of the paper edge height detector, thereby improving the quality of finished cigarettes.

[0006] The applicant has discovered that the reasons for the false detection of the paper edge height detector in the prior art are:

[0007] Since the suction mechanism, the paper edge height detector and the glue gun are arranged in sequence along the conveying direction of the conveying channel, and the suction mechanism and the detection mechanism are located on the same side of the conveying channel, the cigarette dust in production and the glue liquid produced by the glue gun are mixed and easily adsorbed to the receiving end of the receiver or the transmitting end of the transmitter under the action of the suction mechanism. The mixture is mistakenly identified by the detection mechanism as the paper edge of cigarette paper, thereby causing the paper edge height detector to misdetect.

[0008] To solve the above technical problems, the embodiments of the present utility model disclose a cigarette-making machine for rolling shredded tobacco and cigarette paper into cigarette rods. The cigarette-making machine includes a pressing plate provided with a conveying channel for conveying the cigarette rods along a first direction. The cigarette-making machine also includes:

[0012] A barrier is provided between the detection mechanism and the gluing mechanism, and the barrier is used to prevent the glue output by the gluing mechanism from splashing onto the detection end of the detection mechanism under the action of the negative pressure airflow.

[0013] By adopting the above technical solution, by arranging baffles in the detection mechanism and the gluing mechanism, the mixture of glue liquid and tobacco can be prevented from contacting the detection mechanism, thereby preventing the mixture from adhering to the detection mechanism and causing false detection, thereby keeping the paper edge of the cigarette paper at an appropriate height and improving the qualified rate of finished cigarettes.

[0017] Optionally, the second plate is located outside the conveying channel, and along the width direction of the conveying channel, the projection of the second plate is located outside the projection range of the detection mechanism.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2As shown, the embodiment of the utility model discloses a cigarette making machine for rolling tobacco shreds and cigarette paper into cigarette rods. The cigarette making machine is provided with a base 21 and a pressing plate 1, the pressing plate 1 is connected to the base 21, and a conveying channel 2 is provided on the pressing plate 1. The conveying channel 2 is used to move tobacco along a first direction (such as Figure 1 and Figure 2 The cigarette rod is transported in the X direction. Specifically, the width of the conveying channel 2 is greater than or equal to the diameter of the cigarette rod so that the cigarette rod can pass smoothly. The cigarette making machine also includes a suction mechanism 3, a detection mechanism 5, a baffle 7 and a gluing mechanism 6 arranged in sequence along the first direction. The suction mechanism 3 is connected to the pressing plate 1, and a suction port 4 is provided on the suction mechanism 3. The suction port 4 faces the conveying channel 2, the detection mechanism 5 and the gluing mechanism 6. The suction port 4 can generate a negative pressure airflow for absorbing tobacco dust generated during production. The detection mechanism 5 is provided on the pressing plate 1. The detection mechanism 5 is used to detect the height of the paper edge of the cigarette paper in the conveying channel 2 to ensure that the height of the paper edge is within the set range, thereby improving product quality. The gluing mechanism 6 is provided on the pressing plate 1. The gluing mechanism 6 is used to glue the paper edge of the cigarette paper in the conveying channel 2 so that the two paper edges of the cigarette rod can stick together. Specifically, the gluing end of the gluing mechanism 6 is located on the geometric center line of the conveying channel 2 to improve the gluing effect. The barrier 7 is provided between the detection mechanism 5 and the gluing mechanism 6 , and is used to prevent the glue liquid output by the gluing mechanism 6 from splashing onto the detection end of the detection mechanism 5 under the action of the negative pressure airflow.

[0036] By adopting the above technical solution, a barrier 7 is provided between the detection mechanism 5 and the gluing mechanism 6. The barrier 7 can form a shield on the side of the detection mechanism 5 away from the suction mechanism 3, thereby preventing the mixture of glue and tobacco from contacting the detection mechanism 5, and further preventing the mixture from adhering to the detection mechanism 5 and causing false detection, thereby making the paper edge of the cigarette paper at an appropriate height and improving the qualified rate of finished cigarettes.

[0037] Alternatively, as Figure 2 and Figure 3 As shown, the barrier 7 includes a first plate 8 and a second plate 11. The first plate 8 is arranged on the side of the detection mechanism 5 away from the suction mechanism 3, and the extension direction of the first plate 8 (as shown in FIG. Figure 2The first plate body 8 and the second plate body 11 are connected to each other (as shown in the Y direction) and are perpendicular to the first direction. The first end 9 of the first plate body is close to the conveying channel 2, and the second end 10 of the first plate body is away from the conveying channel 2. The extension direction of the second plate body 11 is parallel to the first direction. The first end 12 of the second plate body is connected to the first end 9 of the first plate body, and the second end 13 of the second plate body is close to the detection area of ​​the detection mechanism 5. In other words, the first plate body 8 and the second plate body 11 constitute a right-angled plate body, which can block the detection end of the detection mechanism 5. When the negative pressure airflow adsorbs the mixture of glue and cigarette end and moves toward the air inlet 4, the right-angled plate body can block the mixture from contacting the detection end of the detection mechanism 5, thereby preventing the mixture of glue and cigarette end from adhering to the detection end of the detection mechanism 5, thereby preventing the detection mechanism 5 from misdetecting.

[0038] Alternatively, as Figure 3 As shown, the second plate 11 is located outside the conveying channel 2 and extends along the width direction of the conveying channel 2 (eg Figure 2 In the Y direction, the projection of the second plate 11 is outside the projection range of the detection mechanism 5. In other words, the second plate 11 does not extend into the conveying channel 2, and the second end 13 of the second plate does not block the detection end of the detection mechanism 5.

[0039] By adopting the above technical solution, on the one hand, since the second plate 11 is located outside the conveying channel 2, when the tobacco rod passes through the conveying channel 2, the second plate 11 will not interfere with the tobacco rod, thereby not damaging the appearance of the tobacco rod. On the other hand, since the projection of the second plate 11 along the width direction of the conveying channel 2 is located outside the projection range of the detection mechanism 5, it is possible to avoid the second end of the second plate 11 blocking the detection end of the detection mechanism 5, thereby not affecting the normal operation of the detection mechanism 5.

[0040] Alternatively, as Figure 3 As shown, the outer surface of the second plate 11 (the surface adjacent to the delivery channel 2 and extending in the first direction) is flush with the inner wall of the delivery channel 2. This arrangement ensures that there is no gap between the second plate 11 and the delivery channel 2, thereby preventing the mixture from accumulating in the gap and gradually expanding, thereby affecting the normal delivery of the tobacco rod.

[0041] Alternatively, as Figure 2 and Figure 3 As shown, it also includes a mounting portion 18 connected to the second end 10 of the first plate body, and the first plate body 8 is connected to the detection mechanism 5 through the mounting portion 18.

[0042] Alternatively, as Figures 1 to 3As shown, the detection mechanism 5 is a photoelectric sensor and includes a first detection unit 14 and a second detection unit 15. One of the first detection unit 14 and the second detection unit 15 is a transmitter, and the other is a receiver. The first detection unit 14 and the second detection unit 15 are located on either side of the conveying channel 2. The mounting portion 18 is connected to the first detection unit 14. In this embodiment, the first detection unit 14 is a transmitter and is provided with a transmitting terminal 19, and the second detection unit 15 is a receiver and is provided with a receiving terminal 20. Both the transmitting terminal 19 and the receiving terminal 20 are detection terminals. Those skilled in the art will appreciate that in other embodiments, the first detection unit 14 can be a receiver and the second detection unit 15 can be a transmitter.

[0043] The transmitter emits a detection beam. When the receiver successfully receives this detection beam, it indicates that the paper edge height is within the set range, and the paper height adjustment is not performed. However, if the mixture adheres to the transmitting end 19, it will block the transmitting end 19. The detection mechanism 5 will mistake the obstruction for the paper edge and incorrectly adjust the paper height, ultimately reducing the quality of the finished cigarettes.

[0044] Alternatively, as Figure 3 As shown, a first mounting groove 16 and a second mounting groove 17 are provided on the pressure plate 1. The first mounting groove 16 and the second mounting groove 17 are symmetrically arranged on both sides of the conveying channel 2 along the geometric center line of the conveying channel 2. The first detection unit 14 and the second detection unit 15 are respectively arranged in the first mounting groove 16 and the second mounting groove 17. There is a first gap (not shown in the figure) between the first detection unit 14 and the first mounting groove 16, and the mounting portion 18 is arranged in the first gap.

[0045] Optionally, the first detection unit 14 is a cylinder, the first mounting groove 16 is a U-shaped groove, and the mounting portion 18 is a curved plate. The first detection unit 14, the mounting portion 18, and the first mounting groove 16 are concentrically arranged. When the mounting portion 18 is inserted into the first gap, the inner surface of the mounting portion 18 fits against the circumferential surface of the first detection unit 14, and the outer surface of the curved plate fits against the inner wall of the first mounting groove 16, thereby improving the secureness of the installation. Furthermore, the mounting portion 18 adopts a snap-fitting method, which facilitates the removal of the barrier member 7 and improves ease of use.

[0046] Optionally, the heights of the first plate 8 and the second plate 11 are both greater than or equal to the height of the first detection unit 14. In other words, the height of the first detection unit 14 is lower than the heights of the first plate 8 or the second plate 11. This arrangement ensures that when the mixture moves toward the air intake 4 under the adsorption effect of the negative pressure airflow, it will not come into contact with the end of the first detection unit 14, thereby preventing false detection by the detection mechanism 5.

[0047] Optionally, the barrier 7 is made of stainless steel. Since both the glue and the cigarette dust contain a certain amount of water, using stainless steel to make the barrier 7 can prevent the barrier 7 from corrosion, thereby increasing the service life of the barrier 7.

[0048] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
