Description

Technical Field

[0001] This application relates to the field of tobacco manufacturing technology, specifically a cleaning device for a feed hood in tobacco processing equipment. Background Technology

[0002] In the tobacco processing industry, the hopper below the tobacco storage tank is a crucial component for tobacco transport, and its internal cleanliness is closely related to the quality of the finished tobacco product. Due to the extremely small distance between the hopper and the vibrating trough below, operators cannot enter the hopper, making thorough cleaning difficult. Over time, a layer of hardened tobacco residue gradually forms on the inner wall of the hopper, which cannot be effectively removed. During normal production, this residue easily detaches and mixes into the tobacco, affecting its purity and ultimately reducing product quality. Furthermore, even when using a method of opening the hopper at the bottom and cleaning its interior by compressed air, all the aforementioned cleaning operations still rely on manual labor. Manual cleaning not only consumes a significant amount of time and manpower, increasing production labor costs, but also has low efficiency and makes it difficult to guarantee the stability and consistency of the cleaning effect, adversely affecting the continuity of yarn production and the stability of product quality. Utility Model Content

[0003] The main purpose of this application is to provide a cleaning device for the feed hood of a tobacco processing equipment, so as to solve multiple problems in the prior art, such as the difficulty in completely removing the tobacco grime that accumulates on the inner wall of the feed hopper, the high dependence of the cleaning operation on manual labor, the existence of cleaning dead corners, and the easy loss of tobacco quality due to impurities.

[0004] To achieve the above objectives, this application provides the following technical solution: A cleaning device for a feed hood in a filament-making machine includes a top plate. Fixed plates are provided on the left and right end walls of the top plate. Multiple hydraulic telescopic rods are provided on the outer wall of the top plate. A connecting plate is provided on the driving bottom wall of each hydraulic telescopic rod. A sliding rod is provided in the middle of the top wall of the connecting plate. A sliding seat is provided on the top wall of the top plate between the hydraulic telescopic rods, with the outer wall of the sliding rod penetrating the inner cavity of the sliding seat. Side plates are provided on both sides of the bottom wall of the connecting plate. A rotating rod is rotatably connected to the inner wall between the side plates via a bearing. A motor is provided on the right side wall of the right side plate, and the right end of the rotating rod is fixedly connected to the output end of the motor via a coupling. A cylinder is interference-fitted to the outer wall of the rotating rod, and a cleaning mechanism is provided on the bottom wall of the cylinder.

[0005] Furthermore, the blowing mechanism includes a connecting rod, a base is provided between the bottom walls of the connecting rod, one end of a connecting tube is provided on the outer wall of the base, a round rod is provided on the bottom wall of the base through multiple connecting seats, and multiple blowing heads are provided on the bottom wall of the round rod.

[0006] Furthermore, a connecting air passage is formed between the connecting pipe, the base, the connecting seat, the round rod, and the blow nozzle.

[0007] Furthermore, the plurality of blow nozzles are arranged at intervals from left to right on the outer wall of the round rod.

[0008] Furthermore, the outer ring of the bearing is fixedly connected to the outer wall of the side plate through the bearing seat, and the inner ring of the bearing is interference-fitted to the outer wall of the rotating rod.

[0009] The technical solution provided in this application may include the following beneficial effects: This device uses a hydraulic telescopic rod to push the blower head into the hopper, and uses a cylinder to drive the blower head to rotate and tilt, which can accurately approach the inclined inner walls on both sides of the hopper. With the compressed air sprayed from the blower head, it can thoroughly clean the tarnish that has hardened on the inner wall, solving the problem that traditional cleaning methods cannot reach deep areas and cannot completely remove tarnish, thus improving the cleanliness of the inside of the hopper. This device efficiently cleans tobacco residue, reducing the possibility of impurities mixing into the tobacco from the source. The stable and thorough cleaning effect helps ensure the consistency of tobacco product quality and reduces the risk of quality fluctuations caused by hygiene issues. This device achieves automatic feeding and unloading of the hopper and adjustment of the blowing head position and angle through a mechanical structure. The entire process does not require manual operation, which not only reduces reliance on manpower and lowers labor costs, but also avoids the inconvenience of operators working in confined spaces, significantly reducing labor intensity. Automated operation can quickly complete the cleaning operation, shorten the cleaning time, help ensure the continuity of silk production, and improve overall production efficiency.

[0014] See Figure 1-2 As shown, a cleaning device for a material discharge cover of a filament-making equipment includes a top plate 1, fixed plates 2 on the left and right end walls of the top plate 1, a plurality of hydraulic telescopic rods 3 on the outer wall of the top plate 1, a connecting plate 4 on the driving bottom wall of the hydraulic telescopic rods 3, a sliding rod 5 in the middle of the top wall of the connecting plate 4, and a sliding seat 6 on the top wall of the top plate 1 located between the hydraulic telescopic rods 3, with the outer wall of the sliding rod 5 penetrating the inner cavity of the sliding seat 6. The bottom wall of the connecting plate 4 is provided with side plates 7 on both sides. The inner side wall between the side plates 7 is rotatably connected to the rotating rod 8 through the bearing. The right side wall of the right side plate 7 is provided with a motor 9, and the right end of the rotating rod 8 is fixedly connected to the output end of the motor 9 through a coupling. The outer wall of the rotating rod 8 is connected with a cylinder 10 through an interference fit. The bottom wall of the cylinder 10 is provided with a cleaning mechanism.

[0015] Furthermore, the cleaning mechanism includes a connecting rod 11, a base 12 is provided between the bottom walls of the connecting rod 11, one end of a connecting pipe 13 is provided on the outer wall of the base 12, and a round rod 15 is provided on the bottom wall of the base 12 through multiple connecting seats 14. Multiple blow heads 16 are provided on the bottom wall of the round rod 15. Compressed air is delivered into the base 12 through the connecting pipe 13, enters the round rod 15 through the connecting seats 14, and is blown out through the blow heads 16 to clean the inner wall of the hopper. By controlling the extension and retraction of the hydraulic telescopic rod 3 and the angle of rotation of the cylinder 10 driven by the motor 9, the blow heads 16 are moved to cover the inclined inner walls on both sides of the hopper to perform a comprehensive cleaning operation on the impurities on the inner wall of the hopper.

[0016] Furthermore, a connecting air passage is formed between the connecting pipe 13, the base 12, the connecting seat 14, the round rod 15, and the blow head 16. Compressed air is delivered to the base 12 through the connecting pipe 13, enters the round rod 15 through the connecting seat 14, and is blown out through the blow head 16 to clean the inner wall of the hopper.

[0017] Furthermore, multiple blowers 16 are arranged from left to right on the outer wall of the cylindrical rod 15. By controlling the extension and retraction of the hydraulic telescopic rod 3 and the angle of rotation of the cylindrical rod 10 driven by the motor 9, the blowers 16 cover and move above the inclined inner walls on both sides of the hopper to perform a comprehensive cleaning operation on the impurities on the inner wall of the hopper.

[0018] Furthermore, the outer ring of the bearing is fixedly connected to the outer wall of the side plate 7 through the bearing seat, and the inner ring of the bearing is interference-fitted to the outer wall of the rotating rod 8. The bearing fixes the rotating rod 8, making it easier for the rotating rod 8 to rotate through the bearing.

[0019] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0020] One specific application of this embodiment is: When using the device, first complete the installation and connection: Securely install the fixing plate 2 of this device on the inner wall of the tobacco storage cabinet by welding or bolting. The installation position must be precisely above the feeding rollers to avoid interference with the operation of the feeding rollers; then seal the other end of the connecting pipe 13 to the output end of the external compressed air blowing equipment to ensure no leakage during the transmission of compressed air. When it is necessary to clean the inclined inner walls of the hopper on both sides, the hydraulic telescopic rod 3 is activated, and its piston rod extends downward, pushing the connecting plate 4 to move downward in sync. This, in turn, drives the slide rod 5, side plate 7, rotating rod 8, motor 9, and cylinder 10 to move downward as a whole. During this process, the cylinder 10 drives the connecting rod 11, base 12, connecting pipe 13, connecting seat 14, round rod 15, and blowing head 16 to move downward in sync, so that the blowing head 16 smoothly enters the cavity of the hopper from inside the tobacco storage cabinet. Once the blow head 16 reaches the preset height inside the hopper, the motor 9 is started. Its output end drives the rotating rod 8 to rotate, which in turn causes the cylinder 10 to rotate around the axis of the rotating rod 8. By adjusting the angle of the cylinder 10, the connecting rod 11, base 12, connecting pipe 13, connecting seat 14, round rod 15 and blow head 16 are simultaneously rotated and tilted until the blow head 16 is precisely aligned with the inclined inner wall of one side of the hopper, and the blow head 16 is kept at the optimal cleaning distance from the inner wall, usually 5-10cm. At this time, the compressed air blowing equipment is started. Compressed air is delivered to the internal cavity of the base 12 through the connecting pipe 13, and then enters the round rod 15 through the guide channel of the connecting seat 14. Finally, it is ejected at high speed from the air outlet of the blower 16 to powerfully clean the inner wall of the hopper and completely remove the attached soot and impurities. During the cleaning process, the vertical position of the blower head 16 in the hopper can be adjusted by precisely controlling the extension and retraction of the hydraulic telescopic rod 3; at the same time, by adjusting the rotation angle of the cylinder 10 driven by the motor 9, the tilt direction and angle of the blower head 16 can be changed, so that the blower head 16 can achieve full coverage moving cleaning across the entire surface of the inclined inner wall on both sides of the hopper, ensuring thorough and complete cleaning of impurities on the inner wall of the hopper without dead angles. After the cleaning operation is completed, turn off the compressed air blowing equipment, control the piston rod of the hydraulic telescopic rod 3 to retract upward, and pull all the downward moving parts such as the connecting plate 4, cylinder 10, base 12, round rod 15 and blowing head 16 to move upward synchronously until each part is reset to the initial installation position in the tobacco storage cabinet, so as to avoid obstructing the normal transportation of tobacco.

[0021] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
