Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a locking device for the airlock channel of a tobacco feeder. Background Technology

[0002] In modern tobacco processing, the tobacco feeder is one of the key pieces of equipment on the cigarette production line. Its main function is to uniformly and stably transport the processed tobacco shreds into the cigarette rolling machine. The performance of the tobacco feeder directly affects the processing efficiency and quality of the tobacco shreds, and thus the final quality of the cigarettes. Traditional tobacco feeders typically use a pneumatic conveying system, which uses negative or positive pressure to transport the tobacco shreds from the hopper to the cigarette rolling machine.

[0003] The airlock passage of a tobacco feeder is a critical link in the tobacco shred conveying process. However, the airlock passage of existing tobacco feeder equipment has poor sealing performance. Due to the wear and vibration generated during the conveying process, leakage is prone to occur at the airlock passage. This not only leads to material waste but may also cause unstable negative or positive pressure, thus affecting the conveying efficiency and uniformity of the tobacco shreds. Furthermore, the airlock passage design of existing tobacco feeders is complex, and the sealing components are prone to wear, requiring frequent replacement and maintenance, which increases costs and downtime. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a locking device for the airlock channel of a wire feeder, which can solve the problems of insufficient sealing performance, complex structure, and easy wear of existing airlock channel openings in wire feeders.

[0005] According to an embodiment of this utility model, a locking device for the airlock channel of a wire feeder includes: a U-shaped mounting shell, fixedly installed on the outside of the wire feeder, with the opening of the U-shaped mounting shell facing the airlock channel; a locking mechanism, including screws and arc-shaped fixing members, wherein there are two screws respectively rotatably disposed at the ends of two wing plates of the U-shaped mounting shell, each screw is threadedly connected to a threaded block, and the arc-shaped fixing member is fixedly disposed on each of the two threaded blocks, with the ends of the two arc-shaped fixing members away from the screws extending outward through the opening of the U-shaped mounting shell and contacting the outer surface of the airlock channel; and a push rod, wherein the end of the U-shaped mounting shell away from the airlock channel has a through hole, the push rod is slidably disposed at the through hole, and both ends of the push rod are provided with linkage mechanisms to connect with the screws on the corresponding sides.

[0006] The technical principle of this utility model is as follows: the worker pushes the push rod into the U-shaped mounting shell. Under the action of the linkage mechanism, the push rod drives the screws on both sides to rotate, which in turn drives the threaded blocks to move in opposite directions synchronously, and then drives the arc-shaped fixing blocks to move in opposite directions, locking and fixing them at the connection between the airlock channel and the air source end. Under the action of the locking mechanism, it is fixed to prevent the connection with the airlock channel from loosening due to mechanical vibration, thereby achieving locking and preventing leakage, and improving the sealing and stability of the airlock pipe opening.

[0007] Furthermore, each of the aforementioned linkage mechanisms includes a sliding block, a drive rack, and a drive gear. Sliding openings are provided on the opposite side walls of the U-shaped mounting housing. The sliding block is slidably disposed at the sliding opening. The end of the sliding block that passes through the U-shaped mounting housing is fixedly connected to the drive rack. The drive gear is rotatably disposed inside the U-shaped mounting housing and engages with the drive gear in a transmission manner. A transmission assembly is provided between the drive gear and the bolt. The drive gear is connected to the screw through the transmission assembly.

[0008] By adopting the above technical solution, while the push rod slides into the U-shaped mounting shell, it can move through the sliding block to drive the drive rack and drive gear to mesh, and then drive the screw to rotate under the action of the transmission component, so that the two arc-shaped fixing parts are gripped at the connection between the airlock channel and the air source end.

[0009] Furthermore, the transmission assembly includes a first bevel gear, a transmission shaft, and a second bevel gear. The first bevel gear is rotatably disposed inside the U-shaped mounting housing, and the drive gear is connected to the first bevel gear in a transmission connection. The transmission shaft is rotatably disposed inside the U-shaped mounting housing, and the second bevel gear is fixedly mounted on the transmission shaft. The first bevel gear and the second bevel gear are in a transmission meshing relationship. A gear assembly is disposed between the transmission shaft and the screw, and the transmission shaft is connected to the screw through the gear assembly.

[0010] By adopting the above technical solution, the drive rack can drive the first bevel gear to rotate while driving the drive gear to rotate, which in turn drives the second bevel gear and the transmission shaft to rotate, ultimately driving the screw to rotate.

[0011] Furthermore, both the drive gear and the first bevel gear are coaxially fixedly connected to a transmission wheel, and the two transmission wheels are connected by a transmission belt.

[0012] By adopting the above technical solution, the drive gear can rotate synchronously with the transmission shaft, thereby enabling the push rod to synchronously drive the arc-shaped fixing part to rotate and be fixedly locked at the connection of the airlock channel.

[0013] Furthermore, the gear assembly includes bevel gear I and bevel gear II, bevel gear I is fixedly mounted on the drive shaft, and bevel gear II is fixedly mounted on the screw, and bevel gear I and bevel gear II engage in transmission meshing.

[0014] By adopting the above technical solution, the linear sliding of the push rod can eventually drive the screw to rotate, thereby driving the threaded block and the arc-shaped fixing part to move towards each other, fixing and locking the connection of the airlock channel, preventing leakage, and improving the stability and sealing of the connection.

[0015] Furthermore, connecting blocks are fixedly provided at both ends of the bottom of the U-shaped mounting shell, the push rod is T-shaped and its lower end is located outside the U-shaped mounting shell, and threaded through holes are provided at the lower ends of the two connecting blocks and the push rod. Locking threaded rods are threadedly connected to the threaded through holes, and locking nuts are provided at both ends of the locking threaded rods that connect with the connecting blocks.

[0016] By adopting the above technical solution, the position of the push rod after movement can be further fixed, thereby fixing the relative position of the two arc-shaped fixing parts, maintaining the connection stability of the airlock channel opening, preventing leakage, and improving the pipeline sealing performance.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a locking mechanism and push rod, when it is necessary to lock the airlock passage, the operator only needs to push the push rod into the U-shaped mounting shell. Under the action of the linkage mechanism, the screw will rotate, thereby fixing the two arc-shaped fasteners at the airlock passage, improving the stability and sealing of the overall connection, preventing leakage at the airlock passage due to mechanical vibration, and helping to maintain the efficiency and uniformity of tobacco delivery. In addition, the locking mechanism has a simple structure and is easy to operate. The operator only needs to replace the arc-shaped fasteners periodically to avoid wear. Attached Figure Description

[0026] like Figure 1-3As shown, an embodiment of this utility model proposes a locking device for the airlock channel of a wire feeder, including a U-shaped mounting shell 1, a locking mechanism 2, and a push rod 3. The U-shaped mounting shell 1 is fixedly installed on the outside of the wire feeder, with its opening facing upwards and towards the airlock channel. The locking mechanism 2 includes a screw 201 and an arc-shaped fixing member 202. There are two screws 201, which are rotatably disposed on both sides of the upper end of the U-shaped mounting shell 1. Each screw 201 is threadedly connected to a threaded block 203, and an arc-shaped fixing member 202 is fixedly disposed on each of the two threaded blocks 203. The ends of the two arc-shaped fixing members 202 away from the screws 201 extend outwards through the through hole of the U-shaped mounting shell 1 and connect with the outer surface of the airlock channel. The end of the U-shaped mounting shell 1 away from the airlock channel has a through hole, and the push rod 3 is slidably disposed at the through hole. Both ends of the push rod 3 are provided with a linkage mechanism 4 to connect with the corresponding screw 201.

[0027] It should be noted that the threads on the two screws 201 are in opposite directions, which can drive the two arc-shaped fixing parts 202 to slide synchronously towards or away from each other; and a sliding limit component is provided between the sliding block 401 and the inner wall of the U-shaped mounting shell 1, which can limit the sliding block 401 to slide only laterally and prevent it from rotating.

[0028] Each linkage mechanism 4 includes a sliding block 401, a drive rack 402, and a drive gear 403. Sliding openings are provided on the opposite side walls of the U-shaped mounting shell 1. The sliding block 401 is slidably disposed at the sliding opening, and the drive rack 402 is fixedly connected to one end of the sliding block 401 that passes through the U-shaped mounting shell 1. The drive gear 403 is rotatably disposed inside the U-shaped mounting shell 1 and meshes with the drive gear. A transmission assembly is provided between the drive gear 403 and the bolt, and the drive gear 403 is connected to the screw 201 through the transmission assembly.

[0029] The transmission assembly includes a first bevel gear 501, a transmission shaft 502, and a second bevel gear 503. The first bevel gear 501 is rotatably disposed inside the U-shaped mounting housing 1, and the drive gear is connected to the first bevel gear 501 in a transmission connection. The transmission shaft 502 is rotatably disposed inside the U-shaped mounting housing 1, and the second bevel gear 503 is fixedly mounted on the transmission shaft 502. The first bevel gear 501 and the second bevel gear 503 are in a transmission mesh. A gear assembly is provided between the transmission shaft 502 and the screw 201, and the transmission shaft 502 is connected to the screw 201 through the gear assembly 7.

[0030] Both the drive gear and the first bevel gear 501 are fixedly connected to a transmission wheel on the same axis, and the two transmission wheels are connected by a transmission belt 6.

[0031] It should be noted that the U-shaped mounting shell 1 has a certain height inside. In order to achieve the linkage effectiveness of the above structure, the heights of the drive gear 403 and the first bevel gear 501 are matched with each other, and they can move synchronously under the action of the transmission wheel and the transmission belt 6, thereby realizing the transmission meshing of the first bevel gear 501 and the second bevel gear 503.

[0032] The gear assembly 7 includes bevel gear I701 and bevel gear II702. Bevel gear I701 is fixedly mounted on the drive shaft 502, and bevel gear II702 is fixedly mounted on the screw 201. Bevel gear I701 and bevel gear II702 are engaged in transmission.

[0033] Connecting blocks 8 are fixed at both ends of the bottom of the U-shaped mounting shell 1. The push rod 3 is T-shaped and its lower end is located outside the U-shaped mounting shell 1. Threaded through holes are opened at the lower ends of the two connecting blocks 8 and the push rod 3. Locking thread rods 9 are threadedly connected to the threaded through holes. Locking nuts 10 are provided at both ends of the locking thread rod 9 that are connected to the connecting blocks 8.

[0034] It should be noted that, in order to prevent the structure from loosening due to mechanical vibration during the operation of the wire feeder and causing the arc-shaped fixing part 202 to shift in the opposite direction, threaded through holes are provided at the lower ends of the connecting block 8 and the push rod 3. When the push rod 3 moves to the appropriate position, simply insert the locking threaded rod 9 into several threaded through holes at the same height and fix it with the locking nut 10 to further fix the final position of the push rod 3, strengthen protection, improve the connection stability of the overall structure, and achieve the connection sealing between the airlock channel and the air source end of the wire feeder.

[0035] In addition, depending on the actual installation requirements, multiple threaded through holes can be set on the connecting block 8 and the push rod 3. The threaded through holes located at the same horizontal height can be connected by a locking threaded rod 9, thereby fixing the relative position of the push rod 3 and the connecting block 8.

[0036] The implementation principle of this application embodiment is as follows: When it is necessary to lock the airlock passage of the wire feeding machine, the operator pushes the push rod 3 into the U-shaped mounting shell 1. The push rod 3 then abuts against and drives the sliding block 401 to slide into the U-shaped mounting shell 1, which in turn drives the drive rack 402 to slide. Through tooth meshing, the drive gear 403 is driven to rotate. Under the action of the transmission wheel and the transmission belt 6, the drive gear 403 drives the first bevel gear 501 to rotate. The first bevel gear 501 and the second bevel gear 503 are meshed, which can drive the transmission shaft 502 to rotate. The transmission shaft 502 drives the bevel gear I701 fixedly connected to it to rotate. The bevel gear I701 and the bevel gear II702 are meshed, which can drive the screw 201 to rotate, so that the threaded block 203 threadedly connected to it slides out of the U-shaped mounting shell 1, which drives the two arc-shaped fixing parts 202 to slide inward and tighten, and fix them tightly at the airlock passage connection, increasing the fixing force.

[0037] When the push rod 3 moves to the appropriate position and the two arc-shaped fixing parts 202 can grip the connection, the locking threaded rod 9 is inserted into the threaded through hole at the appropriate height. Then, the locking nut 10 is rotated to fix its position, which can fix the final position of the arc-shaped fixing part 202, improve the stability of the entire locking structure and the sealing of the airlock passage, and maintain the continuous, stable and uniform feeding of tobacco by the tobacco feeder.
