[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a filter rod sorting device, including: a conveying channel 1, a guide 2, and a driving mechanism 3.

[0032] Specifically, the conveying channel 1 extends vertically, with an inlet 11 at the upper end and an outlet 12 at the lower end. The conveying channel 1 is used to convey filter rods to be sorted.

[0033] The guide member 2 is located below the discharge port 12. The guide member 2 includes a first guide surface 21 and a second guide surface 22. Both the first guide surface 21 and the second guide surface 22 are inclined relative to the vertical direction. The distance between the first guide surface 21 and the second guide surface 22 gradually increases from top to bottom, and the first guide surface 21 and the second guide surface 22 are symmetrically arranged.

[0034] The drive mechanism 3 is connected to the conveying channel 1 or the guide 2. The drive mechanism 3 is used to drive the conveying channel 1 or the guide 2 to move in the horizontal direction, so that the conveying channel 1 and the guide 2 generate relative motion in the horizontal direction. For example, the drive mechanism 3 is a cylinder.

[0035] For the existing filter stick in the completion of the detection of sorting problem, the filter stick sorting device is characterized by comprising a conveying channel 1, a guide piece 2 and a driving mechanism 3, wherein the guide piece 2 is arranged below the conveying channel 1, and the driving mechanism 3 is arranged on the conveying channel 1 and the guide piece 2 and used for driving the conveying channel 1 or the guide piece 2 to move along the horizontal direction.

[0036] Further, the filter stick sorting device further comprises a detection mechanism (not shown in the figure) arranged at the upstream of the conveying channel 1, the detection mechanism is used for detecting the filter stick to be sorted, and outputs a first signal when detecting the unqualified filter stick and outputs a second signal when detecting the qualified filter stick.

[0037] Further, the filter stick sorting device further comprises a control part (not shown in the figure), the control part is electrically connected with the detection mechanism and the driving mechanism 3, and the control part is used for receiving the first signal and the second signal; when the control part receives the first signal, the driving mechanism 3 is controlled to drive the conveying channel 1 or the guide piece 2 to move along the horizontal direction, so that the projection of the discharge port 12 along the vertical direction is located on the first guide surface 21; when the control part receives the second signal, the driving mechanism 3 is controlled to drive the conveying channel 1 or the guide piece 2 to move along the horizontal direction, so that the projection of the discharge port 12 along the vertical direction is located on the second guide surface 22.

[0038] Optionally, the filter stick sorting device further comprises an electromagnetic valve, which is electrically connected with the control part and the driving mechanism 3, and the control part can control the opening or closing of the electromagnetic valve; when the electromagnetic valve is opened, the electromagnetic valve can control the driving mechanism 3 to operate.

[0039] In one specific embodiment, reference is made to Figure 1 ,Figure 4 and Figure 5 The drive mechanism 3 is connected to the guide member 2 via a connector (not shown in the figure). The drive mechanism 3 is used to drive the guide member 2 in the horizontal direction at a first position (e.g., Figure 4 The position of the guide shown) and the second position (such as Figure 5 The guide 2 moves between the positions shown; when the guide 2 is in the first position, the projection of the outlet 12 in the vertical direction is located on the first guide surface 21; when the guide 2 is in the second position, the projection of the outlet 12 in the vertical direction is located on the second guide surface 22.

[0040] Specifically, before entering the conveying channel 1, the filter rods to be sorted are first inspected by a detection mechanism to check parameters such as circumference, roundness, length, and suction resistance. During the inspection process, the control unit receives the inspection information from the detection mechanism in real time and judges whether the filter rods are qualified according to the pre-set judgment criteria. During the inspection process, the filter rods are slowly conveyed into the conveying channel 1 until the detection mechanism completes the inspection, at which point all filter rods are conveyed into the conveying channel 1. Simultaneously, during the inspection process, the control unit makes judgments based on the indicators detected by the detection mechanism. Once all the indicators for the filter rod have been judged, the control unit controls the drive mechanism to move the guide 2 horizontally to either the first or second position. Subsequently, the filter rods fall along the conveying channel 1 and, guided by the guide 2, fall into either the qualified or unqualified collection area. Specifically, refer to... Figure 4 and Figure 5 When the filter rod to be sorted is determined to be a qualified filter rod, the drive mechanism 3 drives the guide 2 to move to Figure 5 The guide member 2 shown is positioned such that the vertical projection of the discharge port 12 of the conveying channel 1 is located on the second guide surface 22. Therefore, the filter rod to be sorted will slide down the second guide surface 22 during its descent and be guided by the second guide surface 22 to the qualified collection area. When the filter rod to be sorted is determined to be an unqualified filter rod, the drive mechanism 3 drives the guide member 2 to move to the second guide surface 22. Figure 4 The guide member 2 shown is positioned such that the vertical projection of the discharge port 12 of the conveying channel 1 is located on the first guide surface 21. Therefore, the filter rods to be sorted will slide down along the first guide surface 21 during their descent and be guided by the first guide surface 21 to the qualified collection area. Through the above sorting process, qualified and unqualified filter rods are classified and recycled, facilitating further analysis of unqualified filter rods by the operator. This allows for rapid adjustment of production process parameters, optimization of equipment settings, and improvement of the overall quality of the filter rods.

[0041] In another specific implementation, such asFigure 2 , Figure 6 and Figure 7 As shown, the drive mechanism 3 is connected to the conveying channel 1, and the drive mechanism 3 is used to drive the conveying channel 1 in the horizontal direction to the third position (e.g., Figure 6 The location of the conveyor channel shown) and the fourth location (such as Figure 7 The conveying channel 1 moves between the positions shown in the diagram; when the conveying channel 1 is in the third position, the vertical projection of the outlet 12 is located on the first guide surface 21; when the conveying channel 1 is in the fourth position, the vertical projection of the outlet 12 is located on the second guide surface 22.

[0042] Specifically, before entering the conveying channel 1, the filter rods to be sorted are first inspected by a testing mechanism to check parameters such as circumference, roundness, length, and suction resistance. During the inspection process, the control unit receives the inspection information from the testing mechanism in real time and judges whether the filter rods are qualified according to the pre-set judgment criteria. During the inspection, the filter rods are slowly conveyed into the conveying channel 1 until the testing mechanism completes the inspection, at which point all filter rods are conveyed into the conveying channel 1. Simultaneously, during the inspection, the control unit makes judgments based on the indicators detected by the testing mechanism. Once all indicators for the filter rod have been judged, the control unit controls the drive mechanism 3 to move the conveying channel 1 horizontally to the third or fourth position based on the judgment results. Subsequently, the filter rods fall along the conveying channel 1 and are guided by the guide 2 into the qualified or unqualified collection area. Specifically, refer to... Figure 6 and Figure 7 When the filter rod to be sorted is determined to be a qualified filter rod, the drive mechanism 3 drives the conveying channel 1 to move to Figure 7 The position of the conveying channel 1 shown is such that the vertical projection of the outlet 12 of the conveying channel 1 is located on the second guide surface 22. Therefore, the filter rod to be sorted will slide down the second guide surface 22 during its descent and be guided by the second guide surface 22 to the qualified collection area. When the filter rod to be sorted is determined to be unqualified, the drive mechanism 3 drives the conveying channel 1 to move to the second guide surface 22. Figure 6 The position of the conveying channel 1 shown is such that the vertical projection of the outlet 12 of the conveying channel 1 is located on the first guide surface 21. Therefore, the filter rods to be sorted will slide down the first guide surface 21 during their descent and be guided by the first guide surface 21 to the qualified collection area. Through the above sorting process, qualified and unqualified filter rods are classified and recycled, which facilitates further analysis of unqualified filter rods by the operator, thereby enabling rapid adjustment of production process parameters, optimization of equipment settings, and improvement of the overall quality of the filter rods.

[0043] In some embodiments, with reference to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , the filter rod sorting device further comprises a sorting collection box 4, and a partition plate 41 vertically arranged is further arranged in the sorting collection box 4, and the partition plate 41 divides the sorting collection box into an unqualified filter rod collection area 42 and a qualified filter rod collection area 43; the filter rod falling from the first guide surface 21 can enter the unqualified filter rod collection area 42, and the filter rod falling from the second guide surface 22 can enter the qualified filter rod collection area 43. Through the arrangement of the partition plate 41 in the sorting collection box 4, the qualified filter rod collection area 43 and the unqualified filter rod collection area 42 are divided, which can prevent the to-be-sorted filter rods from mixing together when falling into the sorting collection box 4, and facilitate subsequent further analysis of the unqualified filter rods.

[0044] Exemplarily, as shown in Figure 3 , the cross-sectional area of the conveying channel 1 gradually decreases from top to bottom, so that the inlet 11 of the conveying channel 1 is larger than the outlet 12, and when the inlet 11 receives the to-be-sorted filter rod conveyed by the detection mechanism, the to-be-sorted filter rod can be prevented from falling outside the device due to the small inlet 11 when being conveyed to the conveying channel 1, thereby improving the reliability of the filter rod sorting device.

[0045] It should be noted that, in the examples and descriptions of the present application, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement "including one" does not exclude the presence of another identical element in the process, method, article or device including the element.
