Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cigarette physical inspection, in particular to a smoke guide and comprehensive test bench. BACKGROUND

[0002] In the cigarette physical inspection, the draw resistance test of the cigarette on the comprehensive test bench is a key step, especially the draw resistance test of the cigarette by the draw resistance test unit. However, the existing draw resistance test unit is prone to detection errors when detecting. Specifically, the comprehensive test bench comprises a circumferential unit and a draw resistance test unit arranged in sequence from top to bottom, and the draw resistance test unit is internally provided with an inner cavity. After the circumferential length of the cigarette is detected by the circumferential unit, the cigarette will fall into the inner cavity of the draw resistance test unit for draw resistance detection. However, when the cigarette falls through the circumferential unit, the cigarette position will be offset due to the rotation of the circumferential unit, and the cigarette cannot accurately enter the inner cavity of the draw resistance test unit frequently. This problem not only leads to inaccurate test data, but also often causes equipment alarm, affecting the normal operation of the comprehensive test bench. SUMMARY

[0010] When the cover plate is rotated to the second position, the cover plate is separated from the smoke inlet.

[0011] Optionally, the smoke guide further comprises a driving mechanism connected to the cover plate, the driving mechanism being configured to drive the cover plate to rotate.

[0012] Optionally, the smoke guide further comprises a control unit electrically connected to the driving mechanism and the resistance test unit, the control unit being configured to control the cover plate to rotate to the second position when the resistance test unit is in a detection state, and to control the cover plate to rotate to the first position when the resistance test unit is in a non-detection state.

[0013] Optionally, a mounting section is provided on a side of the flow guide channel close to the smoke outlet, the mounting section having a diameter equal to an outer diameter of the resistance test unit, the mounting section being configured to accommodate at least part of the resistance test unit so that an inlet of the resistance test unit is in communication with the flow guide section.

[0014] Optionally, when the resistance test unit is at least partially inserted into the mounting section, the flow guide section, the mounting section and an axis of the resistance test unit are coincident.

[0015] Optionally, a threaded hole is provided on a side wall of the mounting section, the smoke guide further comprising a bolt inserted into and threadedly connected with the threaded hole, the bolt being configured to clamp the resistance test unit inserted into the mounting section so as to lock the resistance test unit.

[0016] Optionally, the cover plate is made of an opaque material.

[0026] In the description of the present embodiment, it should also be noted that unless otherwise explicitly specified and limited, the terms "provided", "connected", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present embodiment can be understood according to the specific circumstances.

[0027] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0028] In view of the problem that the cigarette is difficult to accurately enter the draw resistance test unit in the prior art, the embodiments of the utility model disclose a smoke guide device for guiding the cigarette into the inlet of the draw resistance test unit.

[0029] As shown in Figures 1 to 3 The smoke guide device provided by the application comprises a flow guide head 1, and the flow guide head 1 is provided with a flow guide channel 2 penetrating through the flow guide head 1 along the insertion direction of the cigarette (as indicated by the X direction in Figure 2 The two ends of the flow guide channel 2 are respectively an inlet 3 and an outlet 4 along the insertion direction of the cigarette, and the side of the flow guide channel 2 close to the inlet 3 is provided with a flow guide section 5, the diameter of the flow guide section 5 gradually decreases along the insertion direction of the cigarette, and the minimum diameter of the flow guide section 5 (i.e. the diameter of the bottom of the flow guide section 5) is less than or equal to the inner diameter of the draw resistance test unit 11.

[0030] Referring to Figure 3 When the cigarette needs to be detected, the smoke guide device is arranged between the circumferential unit 10 and the draw resistance test unit 11. Since the diameter of the flow guide section 5 gradually decreases along the insertion direction of the cigarette, the opening on the side of the flow guide section 5 close to the circumferential unit 10 is larger, that is, the flow guide section 5 has a larger receiving area for the cigarette, so that the cigarette output by the circumferential unit 10 can easily fall into the flow guide section 5. Then, the cigarette will slide downward under the guidance of the flow guide section 5. Since the opening on the side of the flow guide section 5 close to the draw resistance test unit 11 is smaller, the flow guide section 5 can better align with the inlet of the draw resistance test unit 11, so that the cigarette output from the flow guide section 5 can smoothly enter the inner cavity 12 of the draw resistance test unit, thereby significantly reducing the failure frequency of the cigarette during the test process of the comprehensive test table, ensuring the stability and accuracy of the measurement, and improving the overall work efficiency.

[0031] Further, in order to ensure that the cigarette can smoothly enter the smoke guide device, the maximum diameter of the flow guide section 5 (i.e. the diameter of the opening at the top of the flow guide section 5) is designed according to the offset amount of the falling cigarette, and the offset amount of the falling cigarette should be less than the maximum diameter of the flow guide section 5. For example, when the offset amount of the falling cigarette is 35 mm and the inner diameter of the draw resistance test unit 11 is 25 mm, the maximum diameter of the flow guide section 5 can be 40 mm and the minimum diameter can be 22 mm.

[0032] When the cigarette falls from the circumferential unit 10, even if the position is offset due to the rotation of the circumferential unit 10, since the offset amount is less than the maximum diameter of the flow guide section 5, the cigarette can still fall into the flow guide section 5, reducing the risk of deviation.

[0033] According to the embodiments of the application, as shown in Figure 1 andFigure 2 As shown, the smoke guide further comprises a cover plate 6 capable of covering the smoke inlet 3. The application does not limit the connection mode of the cover plate 6 and the flow guide head 1. Exemplarily, the cover plate 6 can be buckled on the smoke inlet 3 or be threadedly connected with the smoke inlet 3. As long as the technical solution of covering the smoke inlet 3 by the cover plate 6 can be realized, it is within the protection scope of the application.

[0034] In some embodiments, the cover plate 6 is hinged with the flow guide head 1, and the cover plate 6 is capable of rotating relative to the flow guide head 1 between a first position and a second position. When the draw resistance test unit 11 is working, the cover plate 6 is rotated to the first position, and the cover plate 6 covers the smoke inlet 3. When the draw resistance test unit 11 is not working, the cover plate 6 is rotated to the second position, and the cover plate 6 is separated from the smoke inlet 3. The design of the cover plate 6 can prevent the tobacco or foreign matters of the unmeasured cigarette from entering the draw resistance test unit 11 when the draw resistance test unit 11 is not working, protect the test system, and ensure the accuracy of the test and the normal operation of the equipment.

[0035] According to the embodiments of the application, as shown in Figure 1 The smoke guide further comprises a driving mechanism 7 connected with the cover plate 6 for driving the cover plate 6 to rotate.

[0036] According to the embodiments of the application, the smoke guide further comprises a control part (not shown in the figure) electrically connected with the driving mechanism 7 and the draw resistance test unit 11 respectively, and the control part is used for controlling the cover plate 6 to rotate to the second position when the draw resistance test unit 11 is in the detection state, and controlling the cover plate 6 to rotate to the first position when the draw resistance test unit 11 is in the non-detection state.

[0037] By using the above technical solution, automatic control can be realized. The control part automatically adjusts the opening and closing of the cover plate 6 according to the working state of the draw resistance test unit 11, reduces the need for manual intervention, and ensures that the opening and closing of the cover plate 6 is synchronized with the state of the draw resistance test unit 11, thereby reducing the equipment failure caused by improper operation.

[0038] According to the embodiments of the application, as shown in Figure 2 The side of the flow guide channel 2 close to the smoke outlet 4 is provided with a mounting section 8, and the diameter of the mounting section 8 is equal to the outer diameter of the draw resistance test unit 11. The mounting section 8 is used for accommodating at least part of the draw resistance test unit 11, so that the inlet of the draw resistance test unit 11 is communicated with the flow guide section 5. Specifically, the upper end of the draw resistance test unit 11 can be inserted into the mounting section 8. This design can limit the relative position between the draw resistance test unit 11 and the smoke guide. When the upper end of the draw resistance test unit 11 is inserted into the mounting section 8, the axes of the flow guide section 5, the mounting section 8 and the draw resistance test unit 11 are coincident, so that the opening at the lower end of the flow guide section 5 is aligned with the inlet of the draw resistance test unit 11. Exemplarily, the diameter of the mounting section 8 and the outer diameter of the draw resistance test unit 11 are both 32 mm.

[0039] Further, the side wall of the mounting section 8 is provided with a threaded hole 9, and the smoke guide further comprises a bolt (not shown in the figure), which is inserted into and threadedly connected with the threaded hole 9. When the bolt is locked, the bolt can tightly press the resistance test unit 11 inserted into the mounting section 8, so as to lock the resistance test unit 11 and prevent relative movement between the resistance test unit 11 and the smoke guide.

[0040] According to the embodiment of the present application, the flow guide head 1 and the cover plate 6 are both made of opaque material. The opaque material can effectively block external light, avoid affecting the measurement results due to light interference during the test process, and improve the accuracy of data.

[0041] Although the present application has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood that the above description is intended to be illustrative only and not limiting of the application. Various changes in form and details can be made without departing from the spirit and scope of the application.
