For example, it can be a fixed connection, a detachable connection or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0022] The following will describe the cigarette length detection device of the present utility model in combination with Figure 1 Describe the cigarette length detection device of the present utility model.

[0023] As Figure 1 described, the length detection device provided by the utility model includes a mounting base 1, a support plate 2, a driving mechanism 3, a displacement sensor 4, a detector 5 and a controller. A cigarette 6 can be movably inserted into the mounting base 1. The support plate 2 is located on one side of the mounting base 1, and the cigarette 6 is supported on the support plate 2, and the first end 61 of the cigarette 6 abuts against the support plate 2. The driving mechanism 3 is fixed to the mounting base 1 and connected to the support plate 2 for driving the support plate 2 to move along the length direction of the cigarette 6. The displacement sensor 4 is used to detect the displacement of the support plate 2. The detector 5 is arranged on the other side of the mounting base 1 for detecting the position of the second end 62 of the cigarette 6. The driving mechanism 3, the displacement sensor 4 and the detector 5 are respectively communicatively connected to the controller.

[0024] Specifically, the detector 5 and the driving mechanism 3 are fixed to the mounting base 1, and the detector 5 and the support plate 2 are respectively located on the upper and lower sides of the mounting base 1. Usually, the cigarette 6 is vertically inserted into the mounting base 1, that is, the length direction of the cigarette 6 is parallel to the vertical direction or inclined to the vertical direction. The first end 61 of the cigarette 6, that is, the upper end, is located on the lower side of the mounting base 1 and abuts against the support plate 2, and the second end 62 of the cigarette 6, that is, the lower end, is located on the upper side of the mounting base 1.

[0025] When the driving mechanism 3 drives the support plate 2 to move upward along the length direction of the cigarette 6, it can push the cigarette 6 to move upward, so that the second end 62 of the cigarette 6 enters the measurement area of the detector 5, so that the detector 5 can detect the position of the second end 62 of the cigarette 6. When the driving mechanism 3 drives the support plate 2 to move downward along the length direction of the cigarette 6, the cigarette 6 can fall under its own gravity.

[0026] Before using the length detection device to detect the length of a sample, the device needs to be calibrated. The specific steps are as follows: the controller controls the driving mechanism 3 to drive the support plate 2 to move upward to a set position, and this position is used as the initial position or zero position of the displacement sensor 4. Then, a cigarette 6 with a standard length B is inserted into the mounting base 1 as a standard rod, and the controller controls the driving mechanism 3 to drive the support plate 2 to move downward until the second end 62 of the cigarette 6 is within the measurement area of the detector 5, and then calibration is carried out. At this time, the displacement sensor 4 detects that the displacement of the support plate 2 is A, and a corresponding relationship between the displacement A of the support plate and the length B of the standard rod is established in the controller.

[0027] It should be noted that in the above steps, the support plate 2 can also be first driven to move downward to a set position, and then the support plate 2 is driven to move upward so that the second end 62 of the cigarette 6 is within the measurement area of the detector 5.

[0028] After the calibration check is completed, take out the standard rod and start detecting the length of the cigarette sample to be measured. At this time, the length specification of the cigarette sample to be measured changes. Input the length data of this specification into the controller. The controller calculates a new pallet displacement A' based on this length data and the corresponding relationship between the above-mentioned pallet displacement A and the standard rod length B. After the controller controls the drive mechanism 3 to drive the pallet 2 upward to the set position, it then controls the drive mechanism 3 to drive the pallet 2 downward by the displacement A', so that the second end 62 of the cigarette sample to be measured can be in the measurement area of the detector 5, completing the automatic adjustment of the device.

[0029] The length detection device provided in this embodiment, by setting the displacement sensor 4 and the controller, and the drive mechanism 3, the displacement sensor 4 and the detector 5 are respectively communicatively connected to the controller. The drive mechanism 3 can drive the pallet 2 to move from the set position to the measurement area of the detector 5 where the cigarette 6 is located. At the same time, the displacement sensor 4 detects the displacement of the pallet 2, and then the controller calculates a new displacement according to this displacement, the standard rod length and the length of the sample to be measured. The drive mechanism 3 drives the pallet 2 to move according to the new displacement, so that the sample to be measured can be in the measurement area of the detector 5, realizing the automatic adjustment of the length detection device, automatically adapting to the measurement of cigarette lengths of different specifications, without manual adjustment and multiple calibration checks, saving time and effort.

[0030] The detector 5 in the embodiment of the present utility model can be a laser detector, which includes a transmitter and a receiver. The transmitter and the receiver are respectively arranged on both sides of the cigarette 6. The transmitter emits a laser signal to the receiver, and the controller determines the position information of the second end 62 of the cigarette 6 according to the laser signal received by the receiver. The controller can obtain the distance between the set position where the above-mentioned pallet 2 is located and this position according to this position information. The sum of this distance and the moving displacement A' of the pallet 2 is the measured sample length.

[0031] It should be noted that the detector 5 described in this embodiment is not limited to the above-mentioned laser detector. For example, the detector 5 can also be a camera, and the position information of the second end 62 of the cigarette 6 is determined through the image information collected by the camera.

[0032] The length detection device provided by the present utility model further includes a position sensor 7. The position sensor 7 is fixedly connected to the mounting seat 1 and is used to detect the position of the pallet 2 relative to the mounting seat 1. The position sensor 7 is communicatively connected to the controller. This position sensor 7 can be a contact sensor or a proximity sensor, and can sense the position of the pallet 2 and output the corresponding electrical signal to the controller.

[0033] Specifically, the detection probe of the position sensor 7 faces the pallet 2. The driving mechanism 3 drives the pallet 2 to move up or down. When the position sensor 7 detects a signal, the controller controls the driving mechanism 3 to stop. At this time, the position where the pallet 2 is located is the set position. The controller can control the displacement sensor 4 to zero according to the signal detected by the position sensor 7, and then control the driving mechanism 3 to drive the pallet 2 to move until the second end 62 of the cigarette 6 is within the measurement area of the detector 5.

[0034] In some embodiments, the pallet 2 can be directly driven to the set position by controlling the movement of the driving mechanism 3, such as by controlling the movement stroke of the driving mechanism 3, without detecting the position of the pallet 2 through the position sensor 7.

[0035] The displacement sensor 4 in the length detection device provided by the present utility model includes a grating scale 41 and a grating reading head 42. The grating scale 41 is fixedly connected to the mounting seat 1, and the grating reading head 42 is fixedly connected to the driving end of the driving mechanism 3 and is communicatively connected to the controller.

[0036] Among them, the length direction of the grating scale 41 is consistent with the driving direction of the driving mechanism 3 and the length direction of the cigarette 6. Specifically, the grating scale 41 is arranged in the vertical direction, with one end fixedly connected to the mounting seat 1 and the other end extending downward. The grating reading head 42 moves along the grating scale 41 under the drive of the driving mechanism 3, so as to read the moving distance on the grating scale 41, that is, the moving distance of the pallet 2. When the driving mechanism 3 drives the pallet 2 to move to the set position, the controller controls the grating reading head 42 to zero. The grating scale displacement sensor has the advantages of high detection accuracy, good stability, and simple maintenance and calibration.

[0037] It should be noted that the displacement sensor 4 in the embodiments of the present utility model is a linear displacement sensor, which is not limited to the grating scale displacement sensor described in the above embodiments. Any linear displacement sensor can be actually selected according to the situation.

[0038] The driving mechanism 3 in the length detection device provided by the present utility model includes a motor 31, a lead screw 32, and a nut 33. The motor 31 is fixedly connected to the mounting seat 1, the lead screw 32 is fixedly connected to the driving end of the motor 31, and the nut 33 is threadedly connected to the lead screw 32 and is fixedly connected to the pallet 2.

[0039] Among them, the length direction of the lead screw 32 is consistent with the length direction of the cigarette 6. Specifically, the lead screw 32 is arranged in the vertical direction, with one end fixedly connected to the driving end of the motor 31 and the other end extending downward. The motor 31 drives the lead screw 32 to rotate, thereby driving the nut 33 to move along the length direction of the lead screw 32. The nut 33, as the driving end of the driving mechanism 3, drives the pallet 2 to move.

[0040] When the displacement sensor 4 is a grating displacement sensor, as Figure 1 shown, the nut 33 is also fixedly connected to the grating reading head 42. The motor 31 drives the lead screw 32 to rotate, thereby driving the nut 33 to drive the grating reading head 42 and the pallet 2 to move synchronously. The displacement of the grating reading head 42 is the displacement of the pallet 2.

[0041] The length detection device provided by the present utility model further includes a guide rail 81 and a slider 82. The guide rail 81 is fixedly connected to the mounting base 1, the slider 82 is slidably connected to the guide rail 81, and the slider 82 is fixedly connected to the nut 33.

[0042] Among them, the guide rail 81 is arranged in parallel with the lead screw 32. Specifically, the guide rail 81 is arranged in the vertical direction, one end of which is fixedly connected to the mounting base 1, and the other end extends downward. The lead screw 32 drives the nut 33 to move, and the nut 33 drives the slider 82 and the pallet 2 to move. In this embodiment, by providing the guide rail 81 and the slider 82, under the dual guiding action of the lead screw 32 and the guide rail 81, the movement of the pallet 2 is more stable. Among them, the nut 33 is connected to the pallet 2 through the slider 82, or the slider 82 is connected to the pallet 2 through the nut 33.

[0043] The mounting base 1 in the length detection device provided by the present utility model includes a base plate 11 and a mounting bracket 12. The base plate 11 has a first side face and a second side face opposite to each other. The detector 5 is fixed to the first side face, the mounting bracket 12 is fixed to the second side face, and the driving mechanism 3 and the displacement sensor 4 are fixed to the mounting bracket 12.

[0044] See Figure 1 , the first side face of the base plate 11 is its upper side face, and the second side face of the base plate 11 is its lower side face. The detector 5 is carried and fixed on the first side face. The mounting bracket 12 provides an installation position for the driving mechanism 3 and the displacement sensor 4, facilitating the installation of the driving mechanism 3 and the displacement sensor 4. The position sensor 7 in the above embodiment can also be fixed to the mounting bracket 12.

[0045] Specifically, the mounting bracket 12 is provided with a first connecting portion, a second connecting portion and a carrying portion. The upper ends of the first connecting portion and the second connecting portion are respectively connected to the second side face of the base plate 11, and the lower ends of the first connecting portion and the second connecting portion are connected through the carrying portion. The driving mechanism 3 and the displacement sensor 4 are carried and fixed on the carrying portion.

[0046] An installation space is formed between the first connecting portion, the second connecting portion, the carrying portion and the base plate 11 in this embodiment.

The upper end of the grating scale 41 in the above embodiment is fixedly connected to the carrying portion. The upper end of the guide rail 81 in the above embodiment is fixedly connected to the carrying portion.

[0047] Among them, the first connecting portion, the second connecting portion, and the bearing portion can be integrally formed. For the convenience of device maintenance and installation, the first connecting portion and the second connecting portion are detachably connected to the substrate 11.

[0048] The mounting base 1 in the length detection device provided by the present utility model includes a substrate 11 and a cylinder 13. The substrate 11 is horizontally arranged and has a first side surface and a second side surface facing away from each other. The cylinder 13 penetrates through the first side surface and the second side surface in the vertical direction, and the cylinder 13 is used for inserting a cigarette 6.

[0049] Specifically, the cylinder 13 is provided with a hollow channel, and the size of the hollow channel is slightly larger than the outer diameter of the cigarette 6, providing guidance for the movement of the cigarette 6, so as to ensure that under the action of the pallet 2, the cigarette 6 can move in the vertical direction without tilting left and right.

[0050] Furthermore, the cylinder 13 is detachably connected to the substrate 11. When detecting a cigarette with a longer size, a cylinder 13 with a longer length can be selected to provide longer structural support and guidance for the cigarette 6, avoiding the cigarette 6 from tilting left and right during the up and down movement. When detecting a cigarette with a shorter size, the cylinder 13 with a shorter length can be replaced.
