Description

Technical Field

[0001] This invention relates to the field of tobacco machinery and equipment technology, and more specifically to a feeder lifting belt rake nail cleaning assembly. Background Technology

[0002] In tobacco production, the feeder is a commonly used piece of equipment on the tobacco-making line. The rakes spaced apart on the surface of its discharge conveyor belt easily adhere to substances such as tobacco residue, tar, and flavorings during material transport, forming hard deposits. Currently, the industry primarily cleans these rakes manually. However, due to the inclined angle of the conveyor belt and the large number of rakes, manual cleaning is not only difficult, inefficient, and labor-intensive, but also poses safety hazards. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a feeder elevator rake nail cleaning assembly to solve the problems of low efficiency, poor effect, and safety hazards in manually cleaning the feeder elevator rake nails.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A feeder lifting belt rake cleaning assembly includes a base, a frame is rotatably mounted on the base via a pivot extending left and right, and the tilt angle of the frame relative to the base is adjusted and locked by an angle adjustment mechanism. The frame is equipped with a chain conveying and cleaning mechanism and a spraying mechanism. The chain conveying and cleaning mechanism includes a chain that runs in the left and right direction, and multiple brushes arranged sequentially along the chain running direction on the chain surface. The spraying mechanism includes two sets of spraying components located on the front and rear sides of the chain conveying and cleaning mechanism. Each set of spraying components includes a spray pipe and multiple nozzles set on the spray pipe, which spray atomized water to the brushes of the chain conveying and cleaning mechanism through the nozzles.

[0005] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the angle adjustment mechanism includes a worm gear reducer, a gear, and a sector rack. The rotating shaft is fixedly connected to the frame, and the sector rack is fixedly installed on the rotating shaft and concentric with the rotating shaft. The worm gear reducer is installed on the base, and the gear is fixedly installed on the output shaft of the worm gear reducer. The sector rack has arc-shaped teeth on its arc surface, and the arc-shaped teeth of the sector rack mesh with the gear. The worm gear reducer drives the gear to rotate, and under the meshing action of the gear and the sector rack, the sector rack rotates around the axis of the rotating shaft, thereby driving the frame to rotate.

[0006] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the fan-shaped rack is provided with a limiting block at one end of the arc-shaped tooth, and a stop post is provided on the base. The bottom of the stop post blocks the limiting block, thereby limiting the extreme position of the frame flipping upward relative to the base.

[0007] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the base is provided with a limit switch. When the frame is flipped downward relative to the base to the lower limit position, the bottom of the frame contacts the contact of the limit switch.

[0008] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the chain conveying cleaning mechanism includes two chains arranged side by side and running synchronously, with each brush spanning across the surface of the two chains, and the brushes being installed with the lugs of the outer chain plates of the corresponding chain links of the two chains.

[0009] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the chain conveying and cleaning mechanism further includes a chain reducer. The chain reducer is mounted on a frame, and a drive shaft, a driven shaft, and an intermediate shaft are rotatably mounted on the frame. The output end of the chain reducer is connected to the drive shaft through a coupling. The drive shaft has two drive sprockets arranged side by side, the driven shaft has two driven sprockets arranged side by side, and the intermediate shaft has two intermediate sprockets arranged side by side. Each chain is driven by one drive sprocket and one driven sprocket, and is supported by an intermediate sprocket for rotation of the corresponding middle section of the chain.

[0010] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the front side of the frame is provided with two positioning buckles with slots. Guide positioning rods are horizontally arranged across the bottom of the side plates on the left and right sides of the feeder lifting belt. When the frame is flipped upward to the working position, the slots of the two positioning buckles on the front side of the frame engage with the guide positioning rods.

[0011] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the water inlet of the blow pipe is provided with a quick-connect fitting, and the blow pipe is connected to an external water inlet hose through the quick-connect fitting.

[0012] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the base is provided with a support limiting post to support the bottom of the frame when it is flipped down to the lower limit position.

[0013] As a preferred embodiment of the above-mentioned feeder lifting belt rake cleaning assembly, the frame is provided with a cavity with an open top, the chain conveyor cleaning mechanism is located in the cavity and the brush extends out of the cavity, the two sets of blowing components of the blowing mechanism are located in the cavity, and a sewage pipe communicating with the cavity is provided on one side of the frame.

[0014] Compared with existing technologies, the beneficial effects of this invention are reflected in: This invention provides a cleaning assembly for the rake nails of a feeder elevator. By incorporating a blowing mechanism and a chain conveyor cleaning mechanism, it employs a combined cleaning method of high-pressure spraying and mechanical sweeping. This method effectively cleans hardened deposits on the rake nails of the elevator belt. Furthermore, the running direction of each row of brushes on the chain is perpendicular to the running direction of the elevator belt. This arrangement allows for a larger contact area between the brush bristles and the rake nails, ensuring cleaning force in multiple directions. This layout also makes the cleaning assembly more compact, significantly reducing its width and volume. Through the engagement of two positioning buckles on the front side of the frame with the guide positioning rod below the elevator belt, and with the addition of a movable support structure, the cleaning assembly can reciprocate along the width direction of the elevator belt to clean the rake nails, thus adapting to elevator belts of various widths and improving its versatility. In addition, it eliminates the safety hazards associated with manual cleaning. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 6 This embodiment provides a feeder lifting belt rake cleaning assembly, including a base 1, a frame 2 rotatably mounted on the base 1 via a rotating shaft extending left and right, and an angle adjustment mechanism to adjust and lock the tilt angle of the frame 2 relative to the base 1.

[0024] The frame 2 is equipped with a chain conveyor cleaning mechanism and a spraying mechanism. The chain conveyor cleaning mechanism includes a chain 3 that runs in the left-right direction, and multiple brushes 4 arranged sequentially along the running direction of the chain 3 on the surface of the chain 3. The spraying mechanism includes two sets of spraying components located on the front and rear sides of the chain conveyor cleaning mechanism. Each set of spraying components includes a spray pipe 5 and multiple nozzles 6 arranged on the spray pipe 5. For example, four nozzles 6 can be evenly distributed on the spray pipe 5, with an interval of 240mm between adjacent nozzles 6. The water inlet of the spray pipe 5 is equipped with a quick-connect connector 7, and the spray pipe 5 is connected to a water inlet hose through the quick-connect connector 7. The end of the water inlet hose is connected to a water source through a water pump. The nozzles 6 can be stainless steel fan-shaped nozzles 6, which are installed on the spray pipe by screw connection. The opening of the nozzle 6 is inclined towards the direction of the brushes 4, and atomized water is sprayed onto the brushes 4 of the chain conveyor cleaning mechanism through the nozzles 6.

[0025] The angle adjustment mechanism includes a worm gear reducer 8, a gear 9, and a sector rack 10. The rotating shaft is fixedly connected to the frame 2. Vertical plates are provided on the left and right sides of the base 1. The bottom of the frame 2 is provided with two coaxial rotating shafts on the left and right. The two rotating shafts at the bottom of the frame 2 are respectively hinged to the two vertical plates of the base 1. One of the rotating shafts is the active rotating shaft 11, and the corresponding vertical plate is the active vertical plate 12. The sector rack 10 is fixedly mounted on the drive shaft 11 and is concentric with the drive shaft 11. The worm gear reducer 8 is mounted on the drive vertical plate 12 of the base 1. The gear 9 is fixedly mounted on the output shaft of the worm gear reducer 8. The arc surface of the sector rack 10 is provided with arc teeth 13. The arc teeth 13 of the sector rack 10 mesh with the gear 9. The worm gear reducer 8 drives the gear 9 to rotate. Under the meshing action of the gear 9 and the sector rack 10, the sector rack 10 is driven to rotate around the axis of the drive shaft 11, thereby driving the frame 2 to rotate. This allows the frame 2 to rotate to an angle parallel to the feeder lifting belt 32. The self-locking function of the worm gear reducer 8 is used to lock the frame 2 at any angle within a certain angle range.

[0026] The fan-shaped rack 10 is fixedly connected to a limit block 14 by screws at one end of the arc-shaped tooth 13. The limit block 14 is a Z-shaped block. A stop post 15 is welded to the outside of the active vertical plate 12 of the base 1. The bottom of the stop post 15 blocks the limit block 14, thereby limiting the extreme position of the frame 2 relative to the base 1 when it flips upward, ensuring safe operation.

[0027] A limit switch 16 is provided on the inner side of the active vertical plate 12 of the base 1. When the frame 2 is flipped downward relative to the base 1 to the lower limit position, the bottom of the frame 2 contacts the contact of the limit switch 16. The lower limit position of the frame 2 can be set to be parallel to the base 1, both being in a horizontal state. When the frame 2 is flipped downward to the horizontal state, the bottom of the frame 2 will touch the contact of the limit switch 16, triggering the signal of the limit switch 16 and transmitting it to the control system. The control system then controls the worm gear reducer 8 to stop, thus stopping the rotation of the frame 2.

[0028] The base 1 is also equipped with a support limit post 17 to support the bottom of the frame 2 when it is flipped down to the lower limit position. When the frame 2 is flipped down to the horizontal position, if the limit switch 16 fails, the support limit post 17 can act as a physical limit safety protection component to support the horizontal frame 2 and prevent the frame 2 from continuing to flip down, thus playing a safety protection role.

[0029] The chain conveyor cleaning mechanism includes two chains 3 arranged side-by-side and operating synchronously. Each brush 4 is straddling the surface of the two chains 3. The base 18 of the brush 4 is installed to the lugs of the corresponding chain links of the two chains 3 via screws. The chain conveyor cleaning mechanism also includes a chain reducer 19, which is installed on the rear side of the frame 2. The frame 2 is rotatably mounted with a driven shaft 20, an intermediate shaft 21, and a drive shaft 22 arranged sequentially from left to right. The axial directions of the drive shaft 22, driven shaft 20, and intermediate shaft 21 all extend in the front-rear direction and are rotatably mounted on a support 25 via bearings 24. The support 25 is fixedly installed in the inner cavity of the frame 2. The output end of the chain reducer 19 is connected to the drive shaft 22 via a coupling 23, which can be a cross coupling 23. To accommodate the synchronous transmission of the two chains 3, the drive shaft 22 has two parallel drive sprockets, the driven shaft 20 has two parallel driven sprockets, and the intermediate shaft 21 has two parallel intermediate sprockets. Each chain 3 is connected by one drive sprocket and one driven sprocket, and is supported by an intermediate sprocket for rotation in the middle section of the corresponding chain 3. During operation, the chain reducer 19 drives the drive shaft 22 to rotate, and under the transmission of each sprocket, the two chains 3 rotate synchronously in the left-right direction, causing the brushes 4 on the surface of the two chains 3 to rotate along with the chains 3.

[0030] Two positioning buckles 26 are provided on the front side of the frame 2. The positioning buckles 26 are installed on the front side of the frame 2 by means of screw connection. The upper front side of the positioning buckle 26 has a slot 27. The bottom of the side plates 31 on both sides of the feeder lifting belt 32 is provided with guide positioning rods 28. When the frame 2 is flipped upward to the working position (i.e. parallel to the lifting belt 32), the slots 27 of the two positioning buckles 26 on the front side of the frame 2 are engaged with the guide positioning rods 28 to ensure the stability of the cleaning assembly during operation. When the cleaning assembly is equipped with a movable support structure, it can also realize the sliding positioning and reciprocating movement of the cleaning assembly relative to the width direction of the lifting belt 32, so as to adapt to the cleaning requirements of lifting belts 32 with various width specifications.

[0031] The frame 2 has an open-top cavity 29. The chain conveyor cleaning mechanism is located in the cavity 29, and the brush 4 extends out of the cavity 29. The two sets of blowing components of the blowing mechanism are located in the cavity 29. A drain pipe 30 communicating with the cavity 29 is provided on one side of the frame 2. Wastewater generated during the operation of this cleaning assembly enters the cavity 29 and is discharged through the drain pipe 30 connected to an external drain hose.

[0032] During installation, the base 1 of the cleaning assembly is fixedly installed on the ground or platform below the feeder lifting belt 32, or the cleaning assembly is placed below the feeder lifting belt 32 via a movable support structure, ensuring that the running direction of the chain 3 is perpendicular to the running direction of the lifting belt 32. Then, the frame 2 is rotated to an angle parallel to the lifting belt 32 via the angle adjustment mechanism, and is secured to the guide positioning rod 28 by the slots 27 of the two positioning buckles 26 on the front side of the frame 2, to ensure the stability of the frame 2 and the components mounted on it.

[0033] After the feeder stops production, when it is necessary to clean the rakes 33 on the lifting belt 32, the drive source of the lifting belt 32 is turned on to make the lifting belt 32 run idle. Then, the chain conveyor cleaning mechanism and the spraying mechanism are started. The brushes 4 on the surface of the two chains 3 move synchronously with the two chains 3. Each brush 4 cleans the rakes 33 on the lower surface of the lifting belt 32 along the width direction of the lifting belt 32. At the same time, the cleaning water is atomized by the nozzles 6 on the spray pipes 5 on both sides and sprayed onto the surface of the brushes 4, which softens the dirt on the rakes 33 and further improves the cleaning effect. The wastewater generated during cleaning falls into the lower cavity 29 and is discharged through the external sewage hose connected to the sewage pipe 30.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
