Description

Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a filter rod clamping component and a filter rod clamping device. Background Art

[0002] The filter rod for cigarettes is an important component in the production process of cigarettes. Through the filter rod, smokers can filter out part of the nicotine and tar generated after the combustion of the cigarette body. During cigarette production, the filter rod and the cigarette body are produced separately, and then they are combined together through later assembly to form a complete marketable cigarette. During production, the standardization of later cigarette packaging needs to be considered. Therefore, there are relatively strict restrictions on the production size of the filter rod to avoid affecting the firmness of the inner lining wrapping of the later cigarette packaging due to the oversize of the filter rod, thereby affecting the overall aesthetics of the cigarette packaging.

[0003] The detection of the filter rod size can be carried out by mechanical detection. The filter rod produced on the production line is clamped by a manipulator and transported to the filter rod length detection device. After the filter rod length detection device detects the length of the collected sample, it is uniformly recycled and processed. The sample detection points of the existing filter rod length detection devices all adopt a design of longitudinal jacks. Generally, the filter rods produced on the production line are horizontally transported. Therefore, during the process of sampling and placing the filter rods by the manipulator, the pose of the filter rods needs to be corrected.

[0004] The adjustment of the pose of the filter rod during sampling and transportation can be completed by an industrial multi-joint robotic arm. However, the end effector of the industrial multi-joint robotic arm usually uses two pneumatic fingers to clamp the filter rod. When the pneumatic fingers grasp the horizontally placed cylindrical filter rod, the filter rod is likely to fall off the pneumatic fingers. Therefore, the existing filter rod clamping device has the problem that the filter rod is likely to fall off. Summary of the Utility Model

The second clamping jaw is connected to the first driving mechanism. The first driving mechanism is used to drive the first clamping jaw and the second clamping jaw to approach or move away from each other. When the first clamping jaw, the second clamping jaw, and the pressing unit are in contact with each other, the filter rod is clamped.

The first clamping jaw is slidably connected to the guide bar, and the second clamping jaw is slidably connected to the guide bar.

[0007] Optionally, the driving component includes a first motor, a first bevel gear, and a second bevel gear. The first motor is fixed to the fixed plate.

[0011] The present application further provides a filter rod clamping device, including the filter rod clamping assembly, a sliding assembly, a second driving mechanism, and a second motor. The sliding assembly is connected to the filter rod clamping assembly. The second driving mechanism is connected to the sliding assembly. The second driving mechanism is configured to drive the sliding assembly to slide. The second motor is connected to the sliding assembly and the filter rod clamping assembly. The second motor is configured to drive the filter rod clamping assembly to rotate. When the sliding assembly slides, it drives the second motor and the filter rod clamping assembly to slide.

[0012] Optionally, the second driving mechanism includes a frame, a power motor, a light bar, and a first lead screw. The power motor is fixed to the frame. The light bar is fixed to the frame and passes through the sliding assembly. The first lead screw is connected to the power motor. The power motor is configured to drive the first lead screw to rotate. The first lead screw passes through the sliding assembly and is screwed to the sliding assembly.

The first driving mechanism is configured to drive the first clamping jaw and the second clamping jaw to approach or separate from each other.

[0072] First Embodiment

[0073] As Figure 1 shown, in this embodiment, a filter rod clamping assembly 1 is provided, which includes a fixing plate 10, a first driving mechanism 11, a pressing unit 12, a first clamping jaw 13 and a second clamping jaw 14. The first driving mechanism 11 is arranged on the fixing plate 10. The pressing unit 12 is fixed to the fixing plate 10. The first clamping jaw 13 is connected to the first driving mechanism 11. The second clamping jaw 14 is connected to the first driving mechanism 11. The first driving mechanism 11 is used to drive the first clamping jaw 13 and the second clamping jaw 14 to approach or separate from each other. When the first clamping jaw 13, the second clamping jaw 14 and the pressing unit 12 are in mutual contact, the filter rod 2 is clamped (the filter rod 2 is as Figure 2 shown).

[0074] Since the filter rod 2 can be clamped by three components: the first jaw 13, the second jaw 14, and the pressing unit 12, compared with clamping the filter rod 2 using two pneumatic fingers, the former has better stability in gripping the filter rod 2, and it is more difficult for the filter rod 2 to fall off.

[0075] For ease of explanation, a rectangular coordinate system O-XYZ is set in some of the drawings. The X-axis is parallel to the width direction of the fixed plate 10. The Y-axis is parallel to the thickness direction of the fixed plate 10. The Z-axis is parallel to the vertical direction. The positive directions of the X-axis, Y-axis, and Z-axis remain the same in each drawing with a coordinate system.

[0076] Please refer to Figure 1 and Figure 2 , the fixed plate 10 can be in an inverted T shape, the first jaw 13 and the second jaw 14 can be in an L shape, and the first jaw 13 and the second jaw 14 can be symmetrically arranged. The widths of the first jaw 13 and the second jaw 14 are less than the length of the filter rod 2 so that when gripping the filter rod 2, both ends of the filter rod 2 can extend beyond the first jaw 13 and the second jaw 14. The first driving mechanism 11 can be a telescopic rod, and its two ends are respectively connected to the first jaw 13 and the second jaw 14. The specific composition of the first driving mechanism 11 and the pressing unit 12 can also refer to the subsequent content of the embodiment.

[0077] As Figure 1 shown, the first driving mechanism 11 can be fixed to the fixed plate 10 by screwing or welding. The top of the pressing unit 12 can be fixed to the bottom of the fixed plate 10 by clamping or screwing. The specific connection manner between the first jaw 13 and the second jaw 14 and the first driving mechanism 11 can refer to the subsequent content of the embodiment. The mutual abutment of the first jaw 13, the second jaw 14, and the pressing unit 12 can be that the right end of the bottom of the first jaw 13, the left end of the bottom of the second jaw 14, and the bottom of the pressing unit 12 abut against each other.

[0078] As Figure 1As shown, optionally, the first driving mechanism 11 includes a driving component 110, a bidirectional lead screw 111, and a guide bar 112. The driving component 110 is fixed to the fixing plate 10. The bidirectional lead screw 111 includes a first thread section 1110 and a second thread section 1111. The first jaw 13 is screwed to the first thread section 1110, and the second jaw 14 is screwed to the second thread section 1111. The helix directions of the first thread section 1110 and the second thread section 1111 are opposite. The driving component 110 is connected to the bidirectional lead screw 111. The driving component 110 is used to drive the bidirectional lead screw 111 to rotate. When the bidirectional lead screw 111 rotates, it drives the first jaw 13 and the second jaw 14 to approach or move away from each other. The guide bar 112 is fixed to the fixing plate 10. The first jaw 13 is slidably connected to the guide bar 112, and the second jaw 14 is slidably connected to the guide bar 112. With such a setting, using one bidirectional lead screw 111 can achieve the mutual approach or separation of the first jaw 13 and the second jaw 14, without separately using driving devices to drive the first jaw 13 and the second jaw 14, making the motion control of the first jaw 13 and the second jaw 14 more convenient.

[0079] As Figure 1 shown, the driving component 110 can be fixed to the fixing plate 10 by screwing or welding. The driving component 110 can be a servo motor, and its output shaft can be coaxially arranged with the bidirectional lead screw 111. The specific composition of the driving component 110 can also refer to the subsequent content of this embodiment. The first thread section 1110 and the second thread section 1111 can be integrally formed and connected. The first thread section 1110 can be a right-handed thread section and be located on the left side of the bidirectional lead screw 111, and the second thread section 1111 can be a left-handed thread section and be located on the right side of the bidirectional lead screw 111.

[0080] As Figure 1 shown, or the first thread section 1110 can be a left-handed thread section located on the left side of the bidirectional lead screw 111, and the second thread section 1111 is a right-handed thread section and is located on the right side of the bidirectional lead screw 111. Screw holes can be provided at the tops of the first jaw 13 and the second jaw 14. The first thread section 1110 can be screwed to the screw hole of the first jaw 13, and the second thread section 1111 can be screwed to the screw hole on the second jaw 14. The specific connection method between the driving component 110 and the bidirectional lead screw 111 can refer to the subsequent content of this embodiment. The first jaw 13 and the second jaw 14 can approach or move away from each other along a direction parallel to the X-axis.

[0081] As Figure 1As shown, a left hinge ear 15 and a right hinge ear 16 can be respectively fixed on the left and right sides of the fixed plate 10. The left end of the bidirectional lead screw 111 can pass through the left hinge ear 15, and the right end of the bidirectional lead screw 111 can pass through the right hinge ear 16. The left hinge ear 15 and the right hinge ear 16 can be symmetrical about the middle plane of the cross bar 401 of the frame 40 (please refer to Figure 5 ). The guide bar 112 can be cylindrical or cuboid-shaped, and the guide bar 112 can be fixed to the bottom of the fixed plate 10 by welding or integrally forming. The tops of the first jaw 13 and the second jaw 14 can be slidably connected to the guide bar 112. For example, perforations or grooves with cross-sections adapted to the cross-section of the guide bar 112 can be provided at the tops of the first jaw 13 or the second jaw 14, and the guide bar 112 can pass through the perforations or grooves to achieve slidable connection with the first jaw 13 and the second jaw 14.

[0082] As Figure 1 shown, optionally, the driving component 110 includes a first motor 1100, a first bevel gear 1101 and a second bevel gear 1102. The first motor 1100 is fixed to the fixed plate 10. The first bevel gear 1101 is connected to the first motor 1100, and the first motor 1100 is used to drive the first bevel gear 1101. The second bevel gear 1102 is connected to the bidirectional lead screw 111, the first bevel gear 1101 meshes with the second bevel gear 1102, and the second bevel gear 1102 is used to drive the bidirectional lead screw 111 to rotate. With such a setting, the first motor 1100 can be longitudinally arranged (that is, the central axis of the first motor 1100 can be parallel to the Z axis), so that the center of gravity of the whole filter rod clamping assembly 1 is closer to the central axis of the filter rod clamping assembly 1, which is beneficial to preventing the filter rod clamping assembly 1 from tilting.

[0083] As Figure 1 shown, the first motor 1100 can be fixed to the upper surface of the bottom plate of the fixed plate 10 by screwing. The first motor 1100 can be a stepping motor or a servo motor. The output shaft of the first motor 1100 can be coaxially arranged with the first bevel gear 1101. The output shaft of the first motor 1100 can be connected to the first bevel gear 1101 through a coupling or a key. The second bevel gear 1102 can be coaxially connected to the right end of the bidirectional lead screw 111 through a key or a coupling. The second bevel gear 1102 can be located on the left side of the right hinge ear 16. The central axis of the second bevel gear 1102 can be perpendicularly arranged with the central axis of the first bevel gear 1101. The first bevel gear 1101 and the second bevel gear 1102 can be located below the fixed plate 10.

[0084] Please also refer to Figure 2 and Figure 3, Optionally, the pressing unit 12 includes a fixing frame 120, a first push rod motor 121, and a pressing head 122. The fixing frame 120 is fixed to the fixing plate 10. The first push rod motor 121 is fixed to the fixing frame 120. The pressing head 122 is connected to the first push rod motor 121. The first push rod motor 121 is used to push the pressing head 122 to move. When the first clamping jaw 13, the second clamping jaw 14, and the pressing head 122 are in mutual contact, the filter rod 2 is clamped. The pressing head 122 is pushed by the first push rod motor 121, which is convenient for unified wiring and electronic control with other motors in the filter rod clamping device, and there is no need to separately arrange control circuits such as air circuits or liquid circuits to achieve driving, reducing the overall layout difficulty of the control circuit when the filter rod clamping device realizes driving.

[0085] Please also refer to Figure 2 and Figure 4 , The fixing frame 120 can be U-shaped, and the bidirectional lead screw 111 can pass through the U-shaped fixing frame 120. The top of the fixing frame 120 can be fixed to the middle position at the bottom end of the fixing plate 10 by means of clamping. The first push rod motor 121 can be fixed to the fixing frame 120 by means of screwing. The pressing head 122 can be connected to the push rod of the first push rod motor 121 by means of welding or screwing. The axial direction of the push rod of the first push rod motor 121 can be parallel to the vertical direction. The first push rod motor 121 can drive the pressing head 122 to move up and down. The first push rod motor 121 can be powered by a battery 123. The battery 123 can be fixed to the battery holder 124. The battery 123 and the battery holder 124 can be arranged on the housing of the first push rod motor 121.

[0086] Please also refer to Figure 1 and Figure 2 , Optionally, the first clamping jaw 13 includes a first arc segment 130, the second clamping jaw 14 includes a second arc segment 140, and the pressing head 122 includes a third arc segment 1220. When the first arc segment 130, the second arc segment 140, and the third arc segment 1220 are in mutual contact, the filter rod 2 is clamped. With such a setting, the first clamping jaw 13, the second clamping jaw 14, and the pressing head 122 can fit more closely to the circumferential surface of the filter rod 2 when clamping the filter rod 2, preventing damage to the filter rod 2 due to non - fitting between the first clamping jaw 13, the second clamping jaw 14, the pressing head 122 and the circumferential surface of the filter rod 2.

[0087] Please also refer to Figure 1 and Figure 2, the first arc segment 130 can be disposed at the right end of the bottom of the first jaw 13, the second arc segment 140 can be disposed at the left end of the bottom of the second jaw 14, and the third arc segment 1220 can be disposed at the bottom end of the pressing head 122. The first arc segment 130 and the second arc segment 140 can be symmetrically and concavely arranged. The arc lengths of the first arc segment 130 and the second arc segment 140 can be one-fourth of the circumference of the filter rod 2. The arc length of the third arc segment 1220 can be one-half of the circumference of the filter rod 2. Rubber films can be respectively pasted on the first arc segment 130, the second arc segment 140, and the third arc segment 1220 to increase the friction force when clamping the filter rod 2.

[0088] Please refer to Figure 1 and Figure 2 , optionally, when the first arc segment 130, the second arc segment 140, and the third arc segment 1220 are in contact with each other, a cylindrical cavity having the same diameter as the filter rod 2 is formed. With such a setting, when the first jaw 13, the second jaw 14, and the pressing head 122 are in contact with each other, the filter rod 2 can be exactly clamped, making the clamping of the filter rod 2 more firm. It can also achieve precise positioning of the clamping positions of the first jaw 13, the second jaw 14, and the pressing head 122, preventing inaccurate positioning when the three clamp the filter rod 2 and damaging the filter rod 2. The materials of the fixing plate 10, the first jaw 13, the second jaw 14, the guiding strip 112, the first bevel gear 1101, the second bevel gear 1102, the pressing head 122, and the fixing frame 120 can be steel.

[0089] Second Embodiment

[0090] As Figure 5 shown, this embodiment includes a filter rod clamping device, which includes a sliding assembly 3, a second driving mechanism 4, a second motor 5, and the filter rod clamping assembly 1 in the first embodiment. The sliding assembly 3 is connected to the filter rod clamping assembly 1. The second driving mechanism 4 is connected to the sliding assembly 3, and the second driving mechanism 4 is used to drive the sliding assembly 3 to slide. The second motor 5 is connected to the sliding assembly 3 and the filter rod clamping assembly 1, and the second motor 5 is used to drive the filter rod clamping assembly 1 to rotate. When the sliding assembly 3 slides, it drives the second motor 5 and the filter rod clamping assembly 1 to slide. Using a single second motor 5 to achieve the rotation of the filter rod clamping assembly 1 has a lower cost compared to using a manipulator with multiple joints to achieve the rotation of the filter rod clamping assembly 1 in the related art.

[0091] As Figure 5As shown, the second driving mechanism 4 may include a frame 40 and a telescopic rod (for example, the telescopic rod may be an electric push rod, a cylinder or a hydraulic cylinder). The telescopic rod may be fixed to the frame 40. The axial direction of the push rod of the telescopic rod may be parallel to the Y-axis and connected to the sliding assembly 3. For the specific composition of the sliding assembly 3 and the second driving mechanism 4, reference may also be made to the subsequent content in this embodiment. The second motor 5 may be a servo motor or a stepper motor. The sliding assembly 3 may be connected to the filter rod clamping assembly 1 through the second motor 5. For the specific connection manner between the sliding assembly 3 and the filter rod clamping assembly 1, reference may be made to the subsequent content in this embodiment. For the connection manner between the second driving mechanism 4 and the sliding assembly 3, reference may be made to the subsequent content in this embodiment.

[0092] As Figure 6 shown, optionally, the second driving mechanism 4 includes a frame 40, a power motor 41, a smooth rod 42 and a first lead screw 43. The power motor 41 is fixed to the frame 40. The smooth rod 42 is fixed to the frame 40, and the smooth rod 42 passes through the sliding assembly 3. The first lead screw 43 is connected to the power motor 41, and the power motor 41 is used to drive the first lead screw 43 to rotate. The first lead screw 43 passes through the sliding assembly 3 and is screwed to the sliding assembly 3. When the first lead screw 43 rotates, it drives the sliding assembly 3 to slide.

[0093] As Figure 6 shown, since the lengths of the smooth rod 42 and the first lead screw 43 are relatively long, therefore, by adopting the driving mode of the smooth rod 42 plus the first lead screw 43, the moving distance range of the sliding assembly 3 can be made larger, and thus it is applicable to different moving distance scenarios. The frame 40 may be in an inverted U shape, and it may include two columns 400 and a cross bar 401, that is, the frame 40 may be a gantry structure. The two ends of the cross bar 401 may be respectively connected to the tops of the two columns 400. The axial direction of the smooth rod 42 and the axial direction of the first lead screw 43 may be parallel to the Y-axis. The length of the smooth rod 42, the length of the first lead screw 43 and the length of the cross bar 401 may be approximately the same.

[0094] As Figure 6 shown, the power motor 41 may be a servo motor or a stepper motor. The output shaft of the power motor 41 may be parallel to the Y-axis, and the central axis of the main body of the power motor 41 may be parallel to the Z-axis, that is, the power motor 41 may be a right-angle motor. The power motor 41 may be fixed to the upper part of the left end of the cross bar 401 by screwing. The output shaft of the power motor 41 may be connected to the left end of the first lead screw 43 through a coupling or a key. The right end of the first lead screw 43 may pass through a lead screw hanger. The lead screw hanger may be fixed to the cross bar 401. The two ends of the smooth rod 42 may be respectively fixed to the cross bar 401 through a smooth rod hanger. The number of the smooth rods 42 may be two, the first lead screw 43 may be located between the two smooth rods 42, and the two smooth rods 42 may be symmetric about the central axis of the first lead screw 43.

[0095] AsFigure 7 As shown, the output shaft of the second motor 5 can be parallel to the X-axis. The second motor 5 can be connected to the bottom of the sliding assembly 3 (for the sliding assembly 3, please refer to Figure 5 , the same below) by screwing. The output shaft of the second motor 5 can be connected to the top of the filter rod clamping assembly 1 by a key. For example, the output shaft of the second motor 5 can be connected to the top of the fixing plate 10 (for the fixing plate 10, please refer to Figure 1 ) by a key. Define the output shaft of the second motor 5 as A1, then the second motor 5 can drive the filter rod clamping assembly 1 to rotate around the A1 axis. A1 can be parallel to the X-axis. The sliding assembly 3 can slide in a direction parallel to the Y-axis.

[0096] Please refer to Figure 6 and Figure 7 simultaneously. Optionally, the sliding assembly 3 includes a sliding mounting block 30, a mounting sleeve 31, and a first connecting block 32. The sliding mounting block 30 includes a through hole 300 and a threaded hole 301. The optical rod 42 passes through the through hole 300, and the first lead screw 43 passes through the threaded hole 301 and is screwed to the threaded hole 301. The axial direction of the through hole 300 and the axial direction of the threaded hole 301 are arranged parallel to each other. When the first lead screw 43 rotates, it drives the sliding mounting block 30 to slide. The mounting sleeve 31 is connected to the sliding mounting block 30. The first connecting block 32 passes through the mounting sleeve 31 and is slidably connected to the mounting sleeve 31. The first connecting block 32 is connected to the filter rod clamping assembly 1 and the second motor 5. The axial direction of the threaded hole 301 and the sliding direction of the first connecting block 32 are arranged perpendicular to each other. With such a setting, the sliding assembly 3 can drive the filter rod clamping assembly 1 to move horizontally (i.e., move parallel to the Y-axis) and can also drive the filter rod clamping assembly 1 to move longitudinally (i.e., move parallel to the Z-axis), improving the movement flexibility of the filter rod clamping assembly 1.

[0097] Please refer to Figure 6 and Figure 7 simultaneously. The sliding mounting block 30 can be in the shape of a cuboid. The mounting sleeve 31 can be in the shape of a cylinder. The sliding mounting block 30 can be fixed to the outer side wall of the mounting sleeve 31 by welding or screwing. The first connecting block 32 can be in the shape of a cylinder. The material of the sliding assembly 3 can be steel. When the first lead screw 43 rotates, it can drive the sliding mounting block 30 to slide left and right in a direction parallel to the Y-axis. When the sliding mounting block 30 slides, it can drive the mounting sleeve 31 and the first connecting block 32 to move left and right in a direction parallel to the Y-axis. The second motor 5 can be fixed to the first connecting block 32 by screwing. The sliding direction of the first connecting block 32 can be parallel to the Z-axis.

[0098] As Figure 7As shown, optionally, the filter rod clamping device further includes a second push rod motor 6. The second push rod motor 6 is connected to the first connection block 32, and the second push rod motor 6 is fixed to the mounting sleeve 31. The second push rod motor 6 is used to push the first connection block 32 to slide. The first connection block 32 is pushed by the second push rod motor 6, which facilitates unified wiring and electric drive with other motors of the filter rod clamping device, and there is no need to separately arrange control circuits such as air circuits or liquid circuits to achieve drive, reducing the overall layout difficulty of the control circuit when the filter rod clamping device realizes drive.

[0099] As Figure 7 shown, the second push rod motor 6 can be a servo motor or a stepper motor. The axial direction of the push rod of the second push rod motor 6 can be parallel to the Z-axis, and the second push rod motor 6 can push the first connection block 32 to slide up and down in a direction parallel to the Z-axis. The push rod of the second push rod motor 6 can be connected to the first connection block 32 through a key or a coupling. The second push rod motor 6 can be fixed to the mounting sleeve 31 by screwing.

[0100] The first motor 1100, the second motor 5, the first push rod motor 121, the second push rod motor 6, and the power motor 41 can be connected to a controller (for example, the controller can be a PLC) through cables and wires. The start and stop of each motor can be controlled by the controller.

[0101] As Figure 5 shown, the filter rod clamping assembly 1 and the filter rod clamping device can be used in the length detection of the filter rod 2. The filter rod conveyor belt 7 and the filter rod length detection device 8 can be located between the two columns 400 of the frame 40. When the filter rod 2 moves on the filter rod conveyor belt 7, the axial direction of the filter rod 2 is parallel to the Y-axis. When it is necessary to clamp the filter rod 2 on the filter rod conveyor belt 7, it is necessary to control the power motor 41 to drive the first lead screw 43 to rotate. After the first lead screw 43 rotates, it drives the sliding assembly 3 and the filter rod clamping assembly 1 to move to the left.

[0102] Please also refer to Figure 1 , Figure 5 and Figure 7 , when the sliding assembly 3 and the filter rod clamping assembly 1 move above the filter rod 2 on the filter rod conveyor belt 7, the controller can control the second push rod motor 6 to start to push the filter rod clamping assembly 1 to move downward. At this time, the distances between the first jaw 13, the second jaw 14, and the pressing head 122 should be far enough to avoid touching the filter rod 2.

[0103] Please also refer to Figure 2 , Figure 3 and Figure 7When the filter rod clamping assembly 1 descends to the appropriate position, the second push rod motor 6 is stopped, and the first motor 1100 is started, causing the first clamping jaw 13 and the second clamping jaw 14 to move closer together to lift the filter rod 2. The first push rod motor 121 is then started to push the pressing head 122 downward. When the first clamping jaw 13, the second clamping jaw 14, and the pressing head 122 abut against each other, the filter rod 2 is precisely clamped by all three.

[0104] like Figure 6 As shown, after the filter rod 2 is clamped by the filter rod clamping assembly 1, the power motor 41 is started to drive the first screw 43 to rotate, so that the sliding assembly 3 and the filter rod clamping assembly 1 move to the right. When the sliding assembly 3 and the filter rod clamping assembly 1 move to the top of the filter rod length detection device 8, the second motor 5 is controlled to start, so that the filter rod clamping assembly 1 rotates around the A1 axis (see A1 axis for details). Figure 7 ) rotate 90 degrees, so that the axis of the filter rod 2 is parallel to the Z axis, and then control the second push rod motor 6 (the second push rod motor 6 please refer to Figure 7 ) is started, and the filter rod clamping assembly 1 is sent down to a suitable position and then stopped.

[0105] Please also refer to Figure 2 、 Figure 3 and Figure 6 Finally, the first motor 1100 and the first push rod motor 121 are controlled to start, so that the first clamping jaw 13, the second clamping jaw 14 and the pressing head 122 are simultaneously away from the filter rod 2 and disengaged from each other, so that the filter rod 2 is released into the filter rod length detection device 8.
