Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a negative pressure detection device for a smoke conveying guide rail. Background Technology

[0002] In daily production at cigarette factories, the cigarette conveying guide rail for slim cigarettes requires a stable negative pressure during the transfer of cigarette sticks. The magnitude of this negative pressure affects the transmission of the cigarette sticks, and stable transmission is essential to ensure the quality of the cigarettes. Inappropriate pressure will cause the cigarette sticks to move unstably on the conveying guide rail, thus affecting the quality of the cigarettes.

[0003] Therefore, the negative pressure of the smoke conveying guide rail needs to be tested before production. Current methods rely on experience, using the smoke stick to gauge the suction strength, which introduces significant errors. During cigarette rolling machine operation, if the negative pressure is too low, the smoke stick cannot be stably adsorbed; if the negative pressure is too high, it causes delays in smoke stick delivery, leading to machine shutdown and quality issues with the cigarettes. Furthermore, individual perceptions of negative pressure vary, so existing testing methods cannot guarantee that the negative pressure is within the appropriate range. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure detection device for a smoke transmission guide rail to solve the technical problems in the prior art. It can accurately measure the magnitude of the negative pressure on the smoke transmission guide rail.

[0005] This utility model provides a negative pressure detection device for a cigarette conveying guide rail, including a cigarette conveying guide rail for a cigarette machine, a negative pressure detection plate, and a negative pressure gauge.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Embodiments of this utility model: such as Figures 1-5 As shown, a negative pressure detection device for a cigarette conveying guide rail includes a cigarette conveying guide rail 1, a negative pressure detection plate 2, and a negative pressure gauge 3. A cigarette bar receiving groove 4 is provided on the top of the cigarette conveying guide rail 1. A connecting protrusion 5 is formed on the bottom of the negative pressure detection plate 2. The connecting protrusion 5 is inserted into the cigarette bar receiving groove 4. A negative pressure transmission hole 6 is provided in the negative pressure detection plate 2. The negative pressure gauge 3 is installed on the top of the negative pressure detection plate 2. The negative pressure gauge 3 measures the negative pressure value in the cigarette bar receiving groove 4 through the negative pressure transmission hole 6.

[0022] The cigarette machine smoke conveying guide rail 1 is existing technology. The cigarette bar receiving groove 4 at the top of the cigarette machine smoke conveying guide rail 1 is used to receive cigarette bars. In order to prevent the cigarette bars from moving outside the cigarette bar receiving groove 4 when they move in the cigarette bar receiving groove 4, two suction holes 7 are opened at the bottom of the cigarette bar receiving groove 4. Two connectors 8 are fixed at the bottom of the cigarette machine smoke conveying guide rail 1. The two suction holes 7 and the two connectors 8 are arranged coaxially. The lower end of the suction hole 7 is connected to the connector 8.

[0023] A suction pipe 9 is installed on each of the two connectors 8. After the upper end of the suction pipe 9 is inserted into the connector 8, it is fixed by pipe clamps or clamps to prevent the upper end of the suction pipe 9 from becoming loose from the connector 8.

[0024] The lower end of the suction pipe 9 is connected to the negative pressure generator, which is existing technology and is not shown in the figure. When the negative pressure generator is working, a negative pressure is generated around the upper end of the two suction holes 7, so that there is an adsorption force around the two suction holes 7 in the cigarette packing groove 4. In this way, when the cigarette moves, it will not move to the outside of the cigarette packing groove 4 under the adsorption force of the negative pressure.

[0025] If the negative pressure around the two adsorption holes 7 is too high, it will cause the tobacco stick to be delayed, while if the negative pressure is too low, the tobacco stick may move into the tobacco stick receiving groove 4. Therefore, the negative pressure value around the two adsorption holes 7 needs to be accurately measured before the equipment is put into operation.

[0026] A detection groove 10 is provided on the connecting protrusion 5 at the bottom of the negative pressure detection plate 2, and the lower opening of the negative pressure transmission hole 6 is located in the middle position inside the detection groove 10. The length of the detection groove 10 is greater than the distance between the two adsorption holes 7, specifically to ensure that the upper ends of the two adsorption holes 7 are both located inside the detection groove 10.

[0027] During testing, the negative pressure detection plate 2 is placed on top of the cigarette conveying guide rail 1 of the cigarette machine, and the connecting protrusion 5 at the bottom of the negative pressure detection plate 2 is inserted into the cigarette bar receiving groove 4. Since the cross-sectional shape and size of the connecting protrusion 5 are the same as those of the cigarette bar receiving groove 4, the outer wall of the connecting protrusion 5 is completely in contact with the groove wall of the cigarette bar receiving groove 4. At this time, the upper ends of the two adsorption holes 7 are located in the detection groove 10.

[0028] Furthermore, the top of the negative pressure detection plate 2 is provided with a pressure gauge mounting hole 11, which is coaxial with the negative pressure transmission hole 6, and the lower end of the pressure gauge mounting hole 11 is connected to the upper end of the negative pressure transmission hole 6. The negative pressure gauge 3 has a negative pressure detection tube 12, which is threadedly connected to the pressure gauge mounting hole 11.

[0029] Since the pressure gauge mounting hole 11, the negative pressure transmission hole 6 and the detection groove 10 are connected, the negative pressure in the detection groove 10 is transmitted to the negative pressure gauge 3 through the negative pressure transmission hole 6 and the pressure gauge mounting hole 11. The negative pressure gauge 3 can measure the negative pressure value in the detection groove 10.

[0030] By measuring with negative pressure gauge 3, the negative pressure value in the tobacco strip receiving groove 4 on the cigarette conveying guide rail 1 of the cigarette machine can be measured quickly and efficiently, saving a lot of time and improving detection efficiency.

[0031] In this embodiment, the dial 13 of the negative pressure gauge 3 is set facing upwards, which facilitates quick reading by the staff. The detection range of the negative pressure gauge 3 is preferably 0-1 Pa. The negative pressure gauge 3 is a commercially available product that can be purchased directly. The negative pressure gauge 3 preferably has a stainless steel shell, and the negative pressure detection tube 12 is preferably made of copper.

[0032] After the test is completed, the negative pressure detection plate 2 can be removed from the smoke conveying guide rail 1 of the cigarette machine.

[0033] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
