Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery, specifically to a rod-shaped material receiving device. Background Technology

[0002] In the tobacco industry, with the continuous upgrading of cigarette making equipment technology, the production speed and automation level of cigarette making machines are increasing, and the amount of auxiliary materials used is also increasing. Insufficient capacity for receiving rod-shaped materials in existing equipment can affect the entire cigarette production line and reduce cigarette output. Furthermore, with the development of new types of cigarettes both domestically and internationally, the use of special rod-shaped materials, such as those containing flavor capsules or paperless hollow rod-shaped materials, is increasing. However, existing equipment, due to functional and structural limitations, can no longer meet the needs of users for receiving these special rod-shaped materials. Therefore, most companies using special rod-shaped materials currently rely on manual feeding to ensure the normal operation of downstream equipment, resulting in low efficiency and high labor intensity.

[0003] Utility model patent CN221739145U discloses a conveying device adaptable to changes in the length of rod-shaped products. It includes a frame, a first horizontal conveying assembly for conveying materials, a vertical conveying assembly with its feed end located at the discharge end of the first horizontal conveying assembly, a second horizontal conveying assembly, a leveling assembly, and an alignment assembly mounted on the frame that pushes the material on the vertical conveying assembly to align their ends. The alignment assembly is used to push and align the material on the vertical conveying assembly, ensuring that the midpoint of the material's length coincides with the midpoint of the vertical conveying assembly. This places the material's center of gravity in the middle of the vertical conveying assembly, improving the stability of the material conveying. Even when materials of different lengths are used, the alignment assembly can still move the material, keeping its center of gravity in the middle of the vertical conveying assembly. However, this device is not suitable for receiving and feeding long-distance or special rod-shaped materials. Utility Model Content

[0004] In order to adapt to long-distance and special rod-shaped material receiving and feeding and improve feeding efficiency, the technical solution adopted by this utility model is: a rod-shaped material receiving device, including a receiving curved track mechanism, a longitudinal conveying mechanism, a through-beam optical fiber mechanism, and a transverse conveying mechanism arranged sequentially along the rod-shaped material receiving path.

[0005] The receiving bend mechanism is used to receive rod-shaped materials in the conveying pipeline and change the direction of movement of the rod-shaped materials.

[0006] The longitudinal conveying mechanism is connected to the discharge end of the receiving curved mechanism and is used to change the movement speed of the rod-shaped material and increase the spacing between adjacent rod-shaped materials.

[0007] The through-beam fiber optic mechanism is connected to the discharge end of the longitudinal conveying mechanism and is used to detect the passage of rod-shaped materials and send the detection signal to the transverse conveying mechanism, as well as to detect the set backflush signal and send the backflush signal to the backflush mechanism.

[0008] The transverse conveying mechanism is connected to the rear of the through-beam optical fiber mechanism and is used to receive rod-shaped materials and change the direction of movement of the rod-shaped materials.

[0009] Based on the above, the receiving curved mechanism includes an arc-shaped base, an arc-shaped channel for rod-shaped materials to pass through is opened inside the arc-shaped base, a dual detection grating is provided at one end of the arc-shaped base, the dual detection grating is used to detect the linear velocity of the rod-shaped materials and to determine the passage status of the rod-shaped materials, and transmit the signal to the through-beam optical fiber mechanism, and a curved inlet is provided at the other end of the dual detection grating.

[0010] The other end of the arc-shaped base is provided with a curved outlet for insertion into the feed end of the longitudinal conveying mechanism.

[0011] Based on the above, the longitudinal conveying mechanism includes a longitudinal conveying base, and a speed-changing channel is provided in the longitudinal conveying base for the passage of rod-shaped materials and for speed change. Relatively rotating reduction gear sets are provided on both sides of the feed end of the speed-changing channel, and relatively rotating acceleration gear sets are provided on both sides of the discharge end of the speed-changing channel.

[0012] Based on the above, the through-beam optical fiber mechanism includes through-beam optical fiber, conduit flange, and conduit for the passage of rod-shaped material;

[0013] The conduit flange is installed on the side of the conduit facing the longitudinal conveying mechanism. The front end of the conduit flange is provided with a telescopic sliding plate that cooperates with the longitudinal conveying mechanism. The telescopic sliding plate is used to receive the rod-shaped material conveyed from the longitudinal conveying mechanism and to drop the rod-shaped material that has not passed through by retraction.

[0014] Based on the above, the transverse conveying mechanism includes a transverse conveying housing, a steering drum, an output shovel assembly, and a buffer and sorting assembly;

[0015] The steering drum is rotatably installed inside the transverse conveying housing. One end of the steering drum is connected to the through-beam optical fiber mechanism. The outer circumference of the steering drum is provided with drum grooves at equal intervals. The drum grooves are used to receive rod-shaped materials transmitted from the through-beam optical fiber mechanism. The other end of the steering drum is adjacent to the buffer and sorting assembly.

[0016] The output shovel plate assembly is obliquely mounted on the transverse conveying housing. The inner end of the output shovel plate assembly is located on one side of the outer circumferential surface of the steering drum. When the rod-shaped material rotates with the steering drum to the output shovel plate assembly, the output shovel plate assembly is used to intercept and shovel out the rod-shaped material from the drum groove.

[0017] The buffer and sorting assembly is installed inside the transverse conveying housing and located on one side of the steering drum, and is used to sort and buffer the rod-shaped material entering the drum groove.

[0018] Based on the above, the buffer and sorting assembly includes a sorting flange, the side of the sorting flange facing the steering drum is an inclined transition helical surface, and a stop gasket is provided on the inclined transition helical surface. The sorting flange is used to stop the rod-shaped material entering the drum groove and to sort the outer end of the rod-shaped material using the helical surface.

[0019] Based on the above, the buffering and sorting assembly further includes a buffer block, which is installed on the inner wall of the transverse conveying housing. The buffer block is used to decelerate the rod-shaped material entering the drum groove through friction.

[0020] Based on the above, the inner surface of the buffer block is a deceleration surface, which is used to slow down the movement speed of the rod-shaped material.

[0021] Specifically, the steering drum's rotation and position switching are controlled by a through-beam optical fiber. The stop shim is used to stop the longitudinal movement of the rod-shaped material. The finishing flange has an inclined transition spiral surface, which is used to control the end faces of the rod-shaped material in the steering drum to align. The output shovel assembly is installed at an angle to the steering drum for smooth output of the rod-shaped material from the steering drum.

[0022] Meanwhile, the conveying requirements of rod-shaped materials of different diameters can be adapted by replacing the guide tubes located on the through-beam optical fiber mechanism.

[0023] This utility model has substantial features and progress compared with the prior art. Specifically, the rod-shaped material receiving device provided by this utility model, when in use, the high-speed rod-shaped material reaches the bending mechanism through the conveying pipe and enters the longitudinal conveying mechanism. The rod-shaped material is decelerated by two pairs of reduction wheels, and then accelerated by the acceleration wheel and thrown out, widening the gap between two continuous rod-shaped materials. The gap between the rod-shaped materials is greater than the length of the rod-shaped materials.

[0024] Meanwhile, the through-beam optical fiber mechanism located in the middle of the receiving device detects the status information of the rod-shaped material. When the rod-shaped material enters the groove of the steering drum, it still has a certain speed. The buffer block controls the rod-shaped material to decelerate, and the longitudinal speed of the rod-shaped material stops after the action of the stop pad.

[0025] When the through-beam fiber optic detector detects each rod-shaped material passing by, the steering drum rotates at a certain angle. As the steering drum rotates, the ends of the rod-shaped materials are uneven. The straightening flange straightens the ends of the rod-shaped materials in the drum groove to make them flat. After the drum rotates at a certain angle, the output shovel plate group installed at an angle to the drum smoothly shovels out the rod-shaped materials, thus completing the conveying process.

[0026] Therefore, this device can receive rod-shaped materials, solving the problem of receiving long-distance and special rod-shaped materials, eliminating the need for manual feeding and improving feeding efficiency. Attached Figure Description

[0034] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0035] Example 1

[0036] This embodiment provides a rod-shaped material receiving device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a receiving bend mechanism 1, a longitudinal conveying mechanism 2, a through-beam optical fiber mechanism 3, and a transverse conveying mechanism 4 arranged sequentially along the receiving path of the rod-shaped material.

[0037] The receiving bend mechanism 1 is used to receive the rod-shaped material 7 in the conveying pipeline and change the direction of movement of the rod-shaped material. The longitudinal conveying mechanism 2 is connected to the discharge end of the receiving bend mechanism 1 and is used to change the movement speed of the rod-shaped material 7 and increase the spacing between adjacent rod-shaped materials 7.

[0038] The through-beam fiber optic mechanism 3 is connected to the discharge end of the longitudinal conveying mechanism 2. It is used to detect the passage of the rod-shaped material 7 and send the detection signal to the transverse conveying mechanism 4, and to detect a set backflushing signal and send the backflushing signal to the backflushing mechanism. The transverse conveying mechanism 4 is connected to the rear of the through-beam fiber optic mechanism 3 and is used to receive the rod-shaped material 7 and change the direction of movement of the rod-shaped material.

[0039] Specifically, if Figure 2 As shown, the receiving curved mechanism 1 includes an arc-shaped base, and an arc-shaped channel 6 is formed inside the arc-shaped base for the rod-shaped material to pass through. A dual-detection grating 5 is provided at one end of the arc-shaped base. The dual-detection grating 5 is used to detect the linear velocity of the rod-shaped material 7 and to determine the passage status of the rod-shaped material, and transmits the signal to the through-beam optical fiber mechanism 3.

[0040] The other end of the dual-detection grating 5 is provided with a curved inlet 9. The other end of the arc-shaped substrate is provided with a curved outlet 8 for insertion into the feed end of the longitudinal conveying mechanism 2.

[0041] like Figure 3 As shown, the longitudinal conveying mechanism 2 includes a longitudinal conveying base, within which a speed-changing channel 13 is provided for the rod-shaped material 7 to pass through and for speed changes. Relatively rotating reduction gear sets are arranged on both sides of the feed end of the speed-changing channel 13, and relatively rotating acceleration gear sets 10 are arranged on both sides of the discharge end of the speed-changing channel 13. Specifically, the two pairs of reduction gear sets can be divided into a first reduction gear set 11 and a first reduction gear set 12.

[0042] like Figure 4As shown, the through-beam fiber optic mechanism 3 includes a through-beam fiber optic cable 15, a conduit flange 16, and a conduit 14 for passing through rod-shaped materials. The conduit flange 15 is installed on the side of the conduit 14 facing the longitudinal conveying mechanism 2. A telescopic sliding plate 17, which cooperates with the longitudinal conveying mechanism 2, is telescopically mounted on the front end of the conduit flange 16. The telescopic sliding plate 17 is used to receive rod-shaped materials conveyed from the longitudinal conveying mechanism 2 and to drop any rod-shaped materials that fail to pass through by retraction. The telescopic sliding plate can be powered by an electric, pneumatic, or hydraulic rod. A telescopic sliding plate cover 23 is provided on the outer side of the telescopic sliding plate 17.

[0043] like Figure 5 The lateral conveying mechanism 4 includes a lateral conveying housing 24, a steering drum 18, an output shovel assembly 19, and a buffer and sorting component.

[0044] The steering drum 18 is rotatably mounted inside the transverse conveying housing 24, and one end of the steering drum 18 is connected to the through-beam optical fiber mechanism 3. The outer circumferential surface of the steering drum 18 is provided with drum grooves 25 at equal intervals, and the drum grooves 25 are used to receive the rod-shaped material 7 transmitted from the through-beam optical fiber mechanism 3. The other end of the steering drum 18 is adjacent to the buffer and sorting assembly.

[0045] The output shovel assembly 19 is obliquely mounted on the transverse conveying housing 24. The inner end of the output shovel assembly 19 is located beside the outer peripheral surface of the steering drum 18. When the rod-shaped material rotates with the steering drum to the output shovel assembly 19, the output shovel assembly 19 is used to intercept and shovel out the rod-shaped material from the drum groove.

[0046] The buffer and sorting assembly is installed inside the transverse conveying housing 24 and located on one side of the steering drum 18, and is used to sort and buffer the rod-shaped material entering the drum groove 25.

[0047] like Figure 6 As shown, the buffer and sorting assembly includes a sorting flange 20. The side of the sorting flange 20 facing the steering drum 18 is an inclined transition spiral surface, which can be used to adjust the flatness of the end face of the rod-shaped material located in the drum groove.

[0048] Example 2

[0049] This embodiment provides a rod-shaped material receiving device. The main difference from Embodiment 1 is that, in this embodiment, the buffering and sorting assembly further includes a buffer block 21. The buffer block 21 is installed on the inner wall of the transverse conveying housing 24, and the buffer block 21 is used to decelerate the rod-shaped material entering the drum groove 25 through friction.

[0050] Example 3

[0051] This embodiment provides a rod-shaped material receiving device. The main difference from Embodiment 1 is that, in this embodiment, the inner surface of the buffer block 21 is a deceleration surface, which is used to slow down the movement speed of the rod-shaped material.

[0052] Example 4

[0053] This embodiment provides a rod-shaped material receiving device. The main difference from Embodiment 1 is that, in this embodiment, a stop gasket 22 is provided on the inclined transition spiral surface, and the sorting flange 20 is used to stop the rod-shaped material entering the drum groove and to sort the outer end of the rod-shaped material using the spiral surface.

[0054] Specifically, the rod-shaped material receiving device provided by this utility model has a dual-detection grating at the front end of the receiving curve mechanism that can detect the linear velocity of the rod-shaped material and determine its passage status. When the through-beam optical fiber detects a specific signal, it will initiate a cleaning program and control the movement of the telescopic slide plate.

[0055] Specifically, when the dual-detection grating detects that there is rod-shaped material passing through the inlet pipe of the receiving bend, the telescopic slide extends and the longitudinal conveying mechanism is activated at the same time to ensure that the rod-shaped material is thrown out by the acceleration wheel group in the longitudinal conveying mechanism and smoothly reaches the through-beam optical fiber.

[0056] When the through-beam optical fiber detects the arrival of the rod-shaped material, it sends a signal to control the steering drum to rotate it by a certain angle.

[0057] When the through-beam optical fiber detects a specific signal, it initiates a cleaning process. The telescopic slide retracts, causing any unpassed rod-shaped material in the receiving device to fall off. Simultaneously, compressed air backflushs the telescopic slide to clear any unpassed waste rods from the channel.

[0058] On the other hand, the rod-shaped material reaches the drum groove of the steering drum through the through-beam optical fiber. Since the rod-shaped material still has a certain initial velocity, the buffer block can be used to control the deceleration of the rod-shaped material, and the stop pad acts on the end face of the rod-shaped material to stop the longitudinal movement of the rod-shaped material.

[0059] Because the rod-shaped material passes through the stop shims, the end faces of the rod-shaped material in the drum groove will be uneven. The flatness of the end faces of the rod-shaped material in the drum groove can be adjusted by using the inclined transition spiral surface of the finishing flange.

[0060] At the same time, after the drum rotates to a certain angle, the rod-shaped material will be blocked and intercepted by the output shovel group because it is higher than the drum groove, and then smoothly shoveled out by the output shovel group.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
