Description

Technical Field

[0001] The utility model relates to the technical field of tobacco detection, in particular to a filter rod conveying device. Background Art

[0002] During cigarette production, the quality of cigarette filter rods is tested through random sampling. In the current random sampling process, operators manually pick up filter rods from the conveyor belt of a filter rod forming machine or cigarette forming machine, and then transfer the filter rods to a filter rod tester for testing of various indicators (for example, physical indicators such as the weight, circumference, roundness, and draw resistance of the filter rod). Alternatively, a filter rod conveyor is used to blow the filter rods into the filter rod tester. However, due to the diversity of filter rod specifications, when blowing filter rods of different specifications, it is necessary to frequently replace manifolds of different specifications so that the gas can accurately impact the filter rods. If the specifications of the manifold and the filter rod do not match, the gas and the filter rod will be deviated, which may result in the filter rod being unable to be successfully blown out, resulting in low convenience and poor versatility.

[0025] The following combination Figure 1-Figure 3 , through specific embodiments and application scenarios, a filter rod conveying device provided by an embodiment of the present invention is described in detail.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a filter rod conveying device, comprising: a seat body 1, a conveying cylinder 2, a diverter plate 3 and a blowing mechanism 4. The seat body 1 has a gas channel 11. The inlet of the gas channel 11 is connected to the gas outlet of the blowing mechanism 4. The diverter plate 3 is fixedly installed at the outlet of the gas channel 11. The diverter plate 3 has a plurality of diverter holes 31 connected to the gas channel 11, and the plurality of diverter holes 31 are distributed at intervals along the circumference of the diverter plate 3. The conveying cylinder 2 is fixed to the diverter plate 3. The interior of the conveying cylinder 2 is connected to the diverter holes 31. The conveying cylinder 2 is used to put the filter rod 100, and the blowing mechanism 4 is used to blow the filter rod 100 into the filter rod detector 200.

[0027] It is understandable that, compared to the traditional method of delivering the filter stick to the filter stick detector 200 by holding the filter stick, the utility model blows the filter stick 100 into the filter stick detector 200 for testing by gas-driven means, which not only improves the detection efficiency of the filter stick 100, but also avoids contamination and damage to the filter stick 100. In some embodiments, the filter stick conveying device also includes a manipulator. The manipulator is used to transfer the filter stick 100 from the conveyor belt of the production line and deliver it to the conveying cylinder 2. While improving the transmission efficiency of the filter stick 100, the manipulator can also avoid contamination and damage to the filter stick caused by manual picking up of the filter stick 100, thereby ensuring the validity of the detection results of the filter stick 100.

[0028] Specifically, if Figure 1 As shown, the seat body 1 can provide support for the diverter plate 3 and the conveying cylinder 2. The blowing mechanism 4 is connected to the inlet of the gas channel 11 to transport gas into the gas channel 11. The gas can be compressed air or an inert gas such as helium or argon. Figure 1 As shown, the diverter plate 3 is fixed between the base 1 and the conveyor cylinder 2. Optionally, the diverter plate 3 can be locked at the outlet of the gas channel 11 using screws or other fasteners. One end of the conveyor cylinder 2 is fixedly mounted on the diverter plate 3. The other end of the conveyor cylinder 2 is arranged opposite to the detection inlet 201 of the filter rod detector 200, so that the filter rod 100 is blown by the pressure of the gas, so that the filter rod 100 moves along the axial direction of the conveyor cylinder 2 into the detection inlet 201.

[0029] like Figure 3 As shown, the diverter plate 3 is provided with a plurality of diverter holes 31 spaced along its circumference. The gas blown out by the blowing mechanism 4 passes through the gas channel 11 and out of the plurality of diverter holes 31 to ensure the uniformity of the air pressure in the conveying cylinder 2, eliminate the blowing dead angle, and ensure that the small-sized filter rods 100 located at the corner of the diverter plate 3 and the conveying cylinder 2 can also be blown into the filter rod detector 200, without the need to frequently replace the diverter plate 3, thereby improving the versatility and ease of use of the entire filter rod conveying device. Optionally, as Figure 3 As shown, the number of the diverter holes 31 is four. Alternatively, the number of the diverter holes 31 can also be six, seven, or ten.

[0030] The present invention provides a filter rod conveying device, which provides support for the diverter plate 3 and the conveying cylinder 2 through a seat body 1. The seat body 1 has a gas channel 11, and gas is blown into the gas channel 11 through a blowing mechanism 4. The gas passes through the gas channel 11 and passes through a plurality of diverter holes 31 to enter the conveying cylinder 2, so that the gas is evenly distributed in the conveying cylinder 2, thereby eliminating the blowing dead corners in the conveying cylinder 2. The user does not need to frequently replace the diverter plate 3 that is compatible with the specifications of the filter rod 100, thereby improving the versatility and ease of use of the filter rod conveying device and improving the conveying efficiency of the filter rod conveying device.

[0031] In some embodiments, the filter rod conveying device further comprises a sensor. The sensor is fixed to a side of the diverter plate 3 facing the conveying drum 2. The sensor is used to sense whether the filter rod 100 has fallen into the conveying drum 2. The sensor is in communication with the blowing mechanism 4.

[0032] When the filter rod 100 is delivered into the conveying tube 2, the sensor can detect the presence of the filter rod 100 and send a sensing signal to the blowing mechanism 4. After receiving the sensing signal, the blowing mechanism 4 starts to run automatically to blow air into the conveying tube 2, thereby blowing the filter rod 100 into the conveying tube 2. It is understandable that during the design and development stage, the time for a single operation of the blowing mechanism 4 can be set. For example, the single blowing time of the blowing mechanism 4 can be set to 3s. After receiving the sensing signal from the sensor, the blowing mechanism 4 continues to blow for 3s, blows the filter rod 100 into the filter rod detector 200, and then automatically stops running. There is no need for the user to manually start or shut down the blowing mechanism 4, which improves the convenience of using the filter rod conveying device. Moreover, the blowing mechanism 4 can be turned on only when the filter rod 100 falls into the conveying tube 2, which helps to reduce the energy consumption of the blowing mechanism 4.

[0033] Specifically, in some embodiments, the filter rod conveying device further includes a controller. Figure 1 and Figure 2 As shown, the blowing mechanism 4 includes a compressed air pump 41, a solenoid valve 42, and an air pipe 43. The air inlet end of the air pipe 43 is connected to the compressed air pump 41. The air outlet end of the air pipe 43 is connected to the inlet of the air channel 11. The solenoid valve 42 is mounted on the air pipe 43. The sensor and the controller are electrically connected, and the controller is electrically connected to the compressed air pump 41 and the solenoid valve 42 respectively.

[0034] It is understandable that the controller can be a single chip microcomputer or a computer. The controller can be fixedly mounted on the outer wall of the base body 1 or the conveying cylinder 2. Optionally, the solenoid valve 42 is an electromagnetic switch valve. The sensor sends a sensing signal to the controller, and the controller can determine whether the filter rod 100 falls into the conveying cylinder 2 based on the sensing signal of the sensor. When the filter rod 100 falls into the conveying cylinder 2, the controller immediately controls the compressed air pump 41 and the solenoid valve 42 to open at the same time. The compressed air of the compressed air pump 41 is transported from the air outlet end of the air pipe 43 to the gas channel 11. The compressed air passes through several diversion holes 31 into the conveying cylinder 2. Under the action of the compressed air pressure, the filter rod 100 is blown into the filter rod detector 200 for detection. After a single blowing is completed, the controller controls the compressed air pump 41 and the solenoid valve 42 to close at the same time.

[0035] In other specific embodiments, Figure 2As shown, the filter rod conveying device also includes a cover sealing cylinder 5 and a drive mechanism. A delivery hole 21 is provided on the side of the conveying cylinder 2 and is connected to the interior of the conveying cylinder 2. The cover sealing cylinder 5 is rotatably mounted on the conveying cylinder 2. The cover sealing cylinder 5 is provided with a connecting hole. The drive mechanism is in transmission connection with the cover sealing cylinder 5 and is used to drive the cover sealing cylinder 5 to rotate, so that the cover sealing cylinder 5 covers the delivery hole 21 or connects the connecting hole to the delivery hole 21. The end of the conveying cylinder 2 away from the diverter plate 3 is used to connect to the detection inlet 201 of the filter rod detector 200.

[0036] Specifically, if Figure 2 As shown, the delivery hole 21 is a strip-shaped hole to facilitate the delivery of the filter rod 100 from the strip-shaped hole into the conveying cylinder 2. The cover seal 5 is sleeved on the outer wall of the conveying cylinder 2 and is rotatable relative to the conveying cylinder 2. The inner wall of the cover seal 5 and the outer wall of the conveying cylinder 2 are in sliding contact to ensure the sealing of the delivery hole 21 by the cover seal 5, and to prevent the gas blown by the blowing mechanism 4 from leaking from the delivery hole 21 and affecting the normal delivery of the filter rod 100. Optionally, a bearing seat can be installed on the outer wall of the conveying cylinder 2, and the cover seal 5 can be installed on the bearing seat to achieve the flexibility of the cover seal 5 to rotate relative to the conveying cylinder 2.

[0037] When the filter rod 100 needs to be dropped in, the driving mechanism drives the sealing cylinder to rotate so that the connecting hole and the dropping hole 21 are arranged relative to each other, thereby ensuring that the filter rod 100 can be dropped into the conveying cylinder 2; when the filter rod 100 has been dropped into the conveying cylinder 2, the driving mechanism drives the cover sealing cylinder 5 to rotate in the opposite direction, so that the connecting hole is away from the dropping hole 21, thereby covering the dropping hole 21 through the wall of the cover sealing cylinder 5, ensuring that the gas blown out by the blowing mechanism 4 will not leak out.

[0038] In some embodiments, the drive mechanism includes a drive member and a gear. The gear is sleeved on a drive shaft of the drive member. The outer wall of the cover seal 5 has a convex tooth structure. The convex teeth of the convex tooth structure are sequentially arranged along the circumference of the cover seal 5. The gear and the convex tooth structure are meshed.

[0039] Alternatively, the drive member may be a stepper motor or a servo motor. The drive shaft of the drive member drives the gear to rotate, which engages with the cam structure, thereby driving the cover cylinder 5 to rotate. As the cover cylinder 5 rotates, the wall of the cover cylinder 5 seals the delivery hole 21 or rotates the connecting hole above the delivery hole 21, connecting the interior of the conveyor cylinder 2 with the outside world, allowing the filter rod 100 to drop from the delivery hole 21 into the conveyor cylinder 2.

[0040] In some embodiments, as Figure 2As shown, a sealing gasket 22 is fixedly sleeved on one end of the conveying cylinder 2 away from the diverter plate 3. The sealing gasket 22 is used to fit the surface of the filter rod detector 200 to block the gap between the conveying cylinder 2 and the detection inlet 201. The sealing gasket 22 fits on the surface of the filter rod detector 200. On the one hand, it can prevent the gas blown out by the blowing mechanism 4 from leaking and affecting the blowing force on the filter rod 100. On the other hand, the sealing gasket 22 blocks the gap between the conveying cylinder 2 and the detection inlet 201 to prevent external dust, bacteria and other impurities from entering the conveying cylinder 2 and the filter rod detector 200, ensuring that the filter rod 100 will not be contaminated during the detection process.

[0041] In some embodiments, as Figure 1 and Figure 2 As shown, the filter rod conveying device further includes a sealing ring 6. The outlet of the gas channel 11 has a limiting edge 32. The sealing ring 6 is sandwiched between the diverter plate 3 and the limiting edge 32 to seal the gap between the gas channel 11 and the diverter plate 3.

[0042] A limiting edge 32 is provided at the outlet of the gas channel 11 to provide support for the sealing ring 6. The sealing ring 6 is sandwiched between the limiting edge 32 and the diverter plate 3, thereby sealing the gap between the diverter plate 3 and the base 1, preventing leakage of the gas blown by the blowing mechanism 4, thereby ensuring that the gas can smoothly pass through the plurality of diverter holes 31, and ensuring that the gas has sufficient blowing force on the filter rod 100.

[0043] Optionally, the sealing ring 6 is an O-type rubber ring.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
