Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a transparent paper balance monitoring mechanism. Background Technology

[0002] The YB55 transparent paper packaging machine wraps a layer of transparent paper around soft and hard cigarette packs, providing sealing, moisture protection, aesthetic appeal, extending shelf life, and increasing product added value. During packaging, the remaining amount of transparent paper needs to be monitored. Existing monitoring methods rely on a roller at the end contacting the transparent paper roll. As the roll diameter decreases, the angle of the detection rod changes, causing a swing arm connected to the detection rod to approach a proximity switch. For example, the cigarette packaging machine pull-wire or transparent paper remaining amount monitoring device described in patent CN211685917U also uses the above principle. This patent also describes adjusting the position of the first bolt in the slot to adjust the vertical position of the detection rod, thereby adjusting the distance between the detection rod and the proximity switch to accommodate monitoring requirements for different auxiliary material structures. However, while this device can adjust the position of the detection rod to adapt to different auxiliary material structures, it cannot determine the reference position of the core of different auxiliary materials during adjustment, making it difficult to accurately adjust the detection trigger position. To address this technical problem, this utility model provides a transparent paper balance monitoring mechanism. Utility Model Content

[0003] The purpose of this invention is to provide a transparent paper balance monitoring mechanism so that the reference position of the roll core can be clearly known during the adjustment process, thereby adjusting the detection trigger position and making the adjustment process more accurate.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A transparency paper remaining quantity monitoring mechanism includes a slider that can slide up and down. The slider is provided with a crossbar and a rotating rod. The crossbar is fixed and has a proximity switch on it. The rotating rod is rotatable. One end of the rotating rod is provided with a sensor for triggering the proximity switch, and the other end of the rotating rod is provided with a pressure roller for pressing down the transparency paper roll. The ends of the crossbar and the rotating rod are connected to springs. An infrared pen is provided at the bottom of the slider.

[0006] Furthermore, it also includes a guide rail, which is vertically arranged and the slider is slidably mounted on the guide rail.

[0007] Furthermore, a top plate is provided at the top of the guide rail, and a screw sleeve is provided on the top plate. A screw rod is threadedly connected in the screw sleeve, and the bottom end of the screw rod is rotatably connected to the slider.

[0008] Furthermore, in the initial state, the proximity switch and the sensing element are in contact, and the plane of the light emitted by the infrared pen is tangent to the bottom of the pressure roller.

[0009] Furthermore, the slider is provided with a shaft post, and the rotating rod is rotatably mounted on the shaft post.

[0010] Furthermore, the proximity switch is a reed switch, and the sensing element is a magnet.

[0011] Furthermore, the rotating rod includes an integrally formed straight section and a curved section, with the pressure roller disposed at the end of the curved section.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a crossbar and a rotating rod on a slider. A pressure roller is provided at the end of the rotating rod. As the transparent paper is consumed, the angle of the rotating rod changes until the sensing element contacts the proximity switch, triggering the proximity switch and sending a signal to the unit. This achieves the purpose of monitoring the remaining amount of transparent paper. In this invention, the crossbar and the rotating rod are connected by a spring to prevent the rotating rod from being pushed apart by human factors.

[0014] The crossbar and rotating rod are set on the slider, the slider is slidably set on the guide rail and is rotatably connected to the slider with a screw, so that the position of the slider can be adjusted by rotating the screw, thereby adapting to auxiliary material cores of different sizes;

[0015] This invention also includes an infrared pen on the slider. The light emitted by the infrared pen is tangent to the bottom of the pressure roller, which makes it easy to know the reference position of the transparent paper core. This allows the detection trigger position to be adjusted according to different core sizes, making the position more accurate. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] refer to Figure 1-4 As shown, this utility model provides a transparent paper balance monitoring mechanism, including a slider 5 that can slide up and down. The slider 5 is provided with a crossbar 6 and a rotating rod 10. Preferably, the crossbar 6 is located on the left side of the slider 5, and the two ends of the rotating rod 10 are respectively located on both sides of the slider 5. The crossbar 6 is fixed and a proximity switch 7 is provided on the crossbar 6, and the rotating rod 10 is rotatable.

[0025] Furthermore, the slider 5 is provided with a shaft post 13, and the rotating rod 10 is rotatably mounted on the shaft post 13. The rotating rod 10 includes an integrally formed straight section and a curved section. The pressure roller 12 is located at the end of the curved section. The curved section is provided to prevent the rotating rod 10 from making tangential contact with the transparent paper roll. If there were no curved section, when the diameter of the transparent paper roll is large, the rotating rod 10 would make direct tangential contact with the transparent paper roll, while the pressure roller 12 would not be able to contact the transparent paper roll. A sensing element 8 for triggering the proximity switch 7 is provided at one end of the rotating rod 10.

[0026] In some embodiments, the proximity switch 7 is a reed switch and the sensing element 8 is a magnet. When the magnet comes into contact with the reed switch, the reed switch is magnetized and generates opposite magnetic poles. When the magnetic force exceeds the elastic force, the reed switch is attracted to form a normally open contact to conduct the circuit. The proximity switch 7 is connected to the alarm module or other modules of the unit, so as to facilitate reminding people.

[0027] The other end of the rotating rod 10 is provided with a pressure roller 12 for pressing down the transparent paper roll. The pressure roller 12 is rotatable. The ends of the crossbar 6 and the rotating rod 10 are connected with springs 9 to prevent the rotating rod from being pushed open by human factors. The bottom of the slider 5 is provided with an infrared pen 11. Preferably, the infrared pen 11 can slide in the front and back direction.

[0028] In addition, this utility model also includes a guide rail 1, which is vertically mounted on the side wall of the unit. The slider 5 is slidably mounted on the guide rail 1. Preferably, the cross-section of the guide rail 1 is "T" shaped to prevent the slider 5 from detaching from the guide rail 1. To facilitate the adjustment of the position of the slider 5, a top plate 2 is provided at the top of the guide rail 1, and a screw sleeve 3 is provided on the top plate 2. A screw rod 4 is threadedly connected to the screw sleeve 3. The bottom end of the screw rod 4 is rotatably connected to the slider 5, so that the slider 5 can be adjusted up and down by rotating the screw rod 4.

[0029] Specifically, in the initial state, the proximity switch 7 and the sensing element 8 are in contact, and the plane where the light emitted by the infrared pen 11 is located is tangent to the bottom of the pressure roller 12. This tangent is a horizontal line, which allows the reference position of different cores 14 to be found based on the light emitted by the infrared pen 11. It should be noted that the reference position of the core 14 mentioned in this utility model is the horizontal tangent line at the top of the core 14, and the height of the slider 5 is adjusted according to this reference position.

[0030] The working process of this utility model is as follows: the transparent paper roll is installed on the unit and the pressure roller 12 is in contact with the top of the transparent paper roll. At this time, the rotating rod 10 is in an inclined state. The infrared pen 11 is turned on and its position is adjusted so that the light emitted by the infrared pen 11 can illuminate the end face of the transparent paper roll. The screw 4 is rotated to adjust the position of the slider 5 so that the light of the infrared pen 11 is tangent to or close to the core of the transparent paper roll. This position is the reference position of the core 14 and also the monitoring and warning position. When the transparent paper roll is gradually consumed, the pressure roller 12 is gradually pressed down. When the bottom of the pressure roller 12 reaches the reference position of the core 14, the sensing element 8 contacts the proximity switch 7, thereby triggering the proximity switch 7.

[0031] 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.
