The output shaft of the motor 27 is connected to the coupling 28. The helical gear 29 is mounted on the output shaft of the coupling 28. The helical gear 29 and the transmission gear on the transition drum 2 are connected via the gearbox 30. The transmission gears in the gearbox 30 are lubricated with lubricating oil.

[0040] Further, in the embodiment, the sampling drum 10 can also be provided with an installation of suction resistance detection device, which is used to detect the suction resistance of each filter rod, and the filter rod with unqualified suction resistance is removed at the subsequent removal drum 7.

When the online detection assembly detects that a filter rod has quality defects and the filter rod runs to the compressed air pipe along the drum outer ring, the control system assembly starts the electromagnetic valve, the compressed air pipe is connected, and the filter rod is blown out of the drum outer ring and falls into the defective product storage place.

[0042] Correspondingly, the structure of the sampling drum 10 is similar to that of the removal drum 7. When sampling is performed, the compressed air pipe can blow the filter rod into the sampling box 21.

The output assembly 9 includes a conveying belt, and the output drum 8 conveys the qualified filter rods to the conveying belt. The filter rods are stacked on the conveying belt and are transported together to the next production process by the belt.

[0044] The conveying device for receiving and transmitting filter rods according to the present application comprises the following working steps:

[0045] S1: According to the length of the produced filter rod, the position of the adjusting ring 11 on the receiving drum outer ring 12 is changed in the axial direction. For example, if the length of the filter rod is long, the adjusting ring 11 is moved to the end away from the valve seat 14 of the receiving drum, so as to accommodate longer filter rods. If the length of the filter rod is short, the adjusting ring 11 is moved to the end close to the valve seat 14 of the receiving drum, so as to accommodate shorter filter rods.

[0046] S2: After the position adjustment of the adjusting ring 11 is completed, the driving assembly is started by the control system assembly. The motor 27 of the driving assembly works, and drives the transition drum 2 to rotate through the gearbox 30, the shaft coupling 28 and the bevel gear 29. The transition drum 2 drives the receiving drum 3 and the sampling drum 10 to rotate through the transmission gears, respectively.

[0047] S3: The filter rod moves at high speed from the side of the receiving drum wheel 3 into the receiving drum wheel groove 1203 in the braking negative pressure area 1304, and is adsorbed by the second suction hole 1202, the filter rod is decelerated until it is stationary in the receiving drum wheel groove 1203, and the filter rod moves in a circle with the receiving drum wheel outer ring 12. When the filter rod rotates to the on-atmosphere area 1302, the negative pressure in the second suction hole 1202 disappears, and the in-place negative pressure area 1303 moves the filter rod axially close to the adjusting baffle 11 through the first suction hole 1201. When the filter rod moves with the receiving drum wheel outer ring 12 to the transmission negative pressure area 1301, the transmission negative pressure area 1301 re-adsorbs the filter rod through the second suction hole 1202 until it is transferred to the transition drum wheel 2.

[0048] S4: The transition drum wheel 2 transfers the filter rod to the sampling drum wheel 10, the control system assembly controls the driving source of the first guide rail 23 to work, the first guide rail 23 transports the sampling box 21 from the initial position to the lower side of the sampling drum wheel 10, and the cleaner 22 blows air to clean the inside of the sampling box 21 during the transportation process. The sampling drum wheel 10 blows the filter rod into the sampling box 21 according to the control of the control system assembly, the driving source of the first guide rail 23 reverses the work, drives the sampling box 21 to move reversely on the first guide rail 23, when the sampling box 21 returns to the initial position, the sensor 20 detects whether there is a filter rod in the sampling box 21, if there is a filter rod, it will feedback information to the control system assembly, the control system assembly receives the information and sends information to the driving source of the second guide rail 24. If there is no filter rod, it will feedback information to the control system assembly, the control system assembly will report an error or sample again from the sampling drum wheel 10.

[0049] S5: The driving source of the second guide rail 24 receives information and drives the lever 25 to move in the long slot, pushes the filter rod into the inner cavity of the swing block 16, and then the swing block 16 rotates to the vertical direction under the action of the swing cylinder 17, then the rotating shaft air pipe is connected, and the compressed air enters the cavity of the swing block 16 from the cavity of the rotating shaft, so as to blow the filter rod into the conveying pipeline 19. The conveying pipeline 19 transports the filter rod to the external detection equipment for specific detection and analysis (such as diameter, air permeability, etc.).

[0050] S6: the sampling drum wheel 10 carries the filter rod to the detection drum wheel 5, wherein the outer side of the sampling drum wheel 10 and the outer side of the detection drum wheel 5 are provided with circumferential surface detectors 6, and the two circumferential surface detectors 6 can realize 360° omnibearing detection of the filter rod. The end surface detector 4 arranged on the outer side of the detection drum wheel 5 can detect the quality defects of the end surface of the filter rod. When the circumferential surface detector 6 and the end surface detector 4 detect that there are defects on the outer periphery of the filter rod, information is transmitted to the control system component, and the control system component is saved. When the filter rod enters the rejection drum wheel 7, the control system component rejects the filter rod. The qualified filter rod is carried to the output component 9 through the output drum wheel 8 and is counted by the counting detector, and then is uniformly transported to the next process through the belt in the output component 9.

[0051] The present application relates to the conveying device for filter rod receiving and transferring, which has the following advantages:

[0052] 1. The air pressure in the braking negative pressure area 1304 on the receiving drum wheel 3 can be automatically adjusted by the receiving drum wheel sector gear 15, so that the receiving of the filter rod is more gentle, and the filter rod can be prevented from being damaged by colliding with the adjusting blocking ring 11. Meanwhile, the in-place negative pressure area 1303 is arranged on the receiving drum wheel 3, so that the position of the filter rod conveying is accurate. In addition, the receiving drum wheel 3 is suitable for filter rods of different specifications and brands, so that the adaptability of the equipment is improved.

[0053] 2. The sampling drum wheel 10, the sampling detection component 1 and the online detection component are arranged, so that the filter rod can be sampled and detected, and the end surface and the circumferential surface of the filter rod can be fully detected.
