Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a vibrating screen cleaning machine. Background Technology

[0002] In cigarette production, vibrating screens (screening devices) are indispensable equipment. The conveying plane of the vibrating screen has a uniformly distributed mesh of a certain size and number, enabling the screening and separation of tobacco leaves. After the vibrating screen is used, the remaining tobacco leaves must be cleaned promptly to ensure the normal operation of subsequent production processes and the stability of product quality. During the conveying process, tobacco stems can easily get stuck in the mesh, causing blockages, which not only affects the screening effect but also requires significant cleaning effort and is difficult to perform. Currently, most production workshops still use manual cleaning for vibrating screens. Manual cleaning of vibrating screens has many drawbacks. On the one hand, because vibrating screens are usually installed at a high position, operators need to work at height, which undoubtedly increases safety risks and easily leads to falls and injuries. On the other hand, manual cleaning is arduous, requiring operators to repeatedly sweep and wipe for extended periods, consuming a large amount of manpower and resulting in low cleaning efficiency, failing to meet the demands of efficient and continuous modern cigarette production. In addition, the effectiveness of manual cleaning is subject to certain subjective and unstable factors, which may lead to incomplete cleaning of the vibrating screen and affect subsequent production.

[0003] To address the above problems, existing technology provides a vibrating screen cleaning device: Publication No. CN116511028A discloses an automatically cleaning anti-clogging vibrating screen, which specifically discloses multiple cleaning brushes disposed above the vibrating screen. The brush heads of the multiple cleaning brushes are connected to the surface of the belt in an upward manner. As the belt rotates, the brush heads of the multiple cleaning brushes are moved downward to brush off the tobacco leaves on the surface of the vibrating screen. Although it can clean the vibrating screen, the area where the cleaning brushes are arranged does not include the feed end of the vibrating screen. Therefore, the prior art cannot achieve timely cleaning of the entire conveying plane of the vibrating screen. Utility Model Content

[0017] like Figures 1 to 10 As shown, this utility model provides a vibrating screen cleaning machine, which includes a main frame and a cleaning mechanism and a traveling mechanism disposed thereon. The main frame provides stable support for the cleaning mechanism and the traveling mechanism. The main frame includes a vibrating screen 1 and vertical support frames symmetrically arranged on the left and right sides of the vibrating screen 1.

By setting the action time of the electric cylinder 13, it controls the electric roller brush 11 to move closer or further away from the conveying plane of the vibrating screen 1. It counts the actual number of cleaning cycles completed by the cleaning mechanism and uses this to determine whether the cleaning mechanism has completed the cleaning work of the residual tobacco leaves in the vibrating screen 1. The control system includes a PLC controller.

[0018] In this embodiment, the vertical support frame provides support for the synchronous belt slide rail 16 on it. The bottom column 2 is vertically fixed to the ground. There are two bottom columns 2, which are arranged side by side at a certain distance. The crossbeam 3 is fixedly connected to the inner top surface of the two bottom columns 2. The crossbeam 3 can connect the two bottom columns 2 together to enhance the structural strength and stability of the vertical support frame. There are two slide rail supports 4. The two slide rail supports 4 are fixed to the outer top surface of the two bottom columns 2 by bolts to provide support points for the installation of the traveling mechanism. Specifically, the vertical support frame located on the left side of the vibrating screen 1 is called the left vertical frame, and the vertical support frame located on the right side of the vibrating screen 1 is called the right vertical frame. Both the left vertical frame and the right vertical frame are equipped with two bottom columns 2, two crossbeams 3, and two slide rail supports 4.

[0019] In this embodiment, the cleaning support serves to support the components on it. The cleaning support spans above the vibrating screen 1 and includes symmetrically arranged square tube columns 5, a square tube beam 6 located at the top of the square tube columns 5 and connecting the symmetrically arranged square tube columns 5 together, and a square tube horizontal frame 7 symmetrically connected to the rear end face of the square tube beam 6. The end of the power shaft 8 is bolted to the front end face of the square tube column 5 in a manner parallel to the square tube beam 6 via a seated bearing 9. As a self-aligning bearing, one end of the roller brush arm 10 is provided with a circular hole I with a keyway. The power shaft 8 passes through the circular hole I of the roller brush arm 10 and the roller brush arm 10 is fastened to the surface of the power shaft 8 through the cooperation of the key and the keyway. The electric roller brush 11 is a spiral steel wire brush roller with a built-in drive motor. When the electric roller brush 11 is energized, it can rotate to clean the tobacco leaves remaining on the surface of the vibrating screen 1. The end of the electric roller brush 11 is connected to the end of the roller brush arm 10 away from the power shaft 8. The electric cylinder Electric cylinder 13 is provided with a cylinder body end and a movable end. The cylinder body end of electric cylinder 13 is connected to the bottom end face of square tube horizontal frame 7 through cylinder body lug 14. The movable end of electric cylinder 13 is connected to one end of rocker arm 12 through Y-type connector 15. The other end of rocker arm 12 is provided with a round hole II with a keyway. The power shaft 8 passes through the round hole II of rocker arm 12 and the rocker arm 12 is fastened to the surface of power shaft 8 through the cooperation of key and keyway. Rocker arm 12 is located between bearing 9 and roller brush swing arm 10. The retraction action of the movable end of electric cylinder 13 can be achieved through the Y-type connector. The head 15 drives the rocker arm 12 to swing around the circular hole II, which in turn drives the power shaft 8 connected to the rocker arm 12 to rotate at a certain angle, thereby driving the roller brush arm 10 to swing around the power shaft 8, so as to ultimately achieve the purpose of driving the electric roller brush 11 connected to the roller brush arm 10 to rise and fall relative to the conveying plane of the vibrating screen 1. The electric roller brush 11 descends to approach the conveying plane of the vibrating screen 1 and cleans the tobacco leaves remaining in the vibrating screen 1. The electric roller brush 11 rises to move away from the conveying plane of the vibrating screen 1 and ends the cleaning process. Specifically, there are two square tube columns 5, a left column and a right column, symmetrically arranged on the left and right sides of the vibrating screen 1. The left and right columns are connected together by square tube beams 6 welded to their tops. There are two square tube horizontal frames 7, a left horizontal frame and a right horizontal frame, symmetrically welded to the rear end face of the square tube beams 6. The left and right ends of the power shaft 8 are connected to the front ends of the left and right columns respectively via bearings 9. There are two roller brush arms 10, a left roller brush arm and a right roller brush arm, symmetrically keyed to the outer surfaces of the left and right ends of the power shaft 8. The bottom ends are connected to the left and right ends of the electric roller brush 11, respectively. Two rocker arms 12 are provided, a left rocker arm and a right rocker arm. The left and right rocker arms are symmetrically keyed to the outer surfaces of the left and right ends of the power shaft 8. The left rocker arm is located between the left roller brush arm and the bearing 9 with a seat located on the front end face of the left column, and the right rocker arm is located between the right roller brush arm and the bearing 9 with a seat located on the front end face of the right column. Two electric cylinders 13 are provided, a left power cylinder and a right power cylinder. The cylinder bodies of the left and right power cylinders are connected to the bottom ends of the left and right horizontal frames respectively via cylinder body lugs 14. The movable ends of the left and right power cylinders are connected to the bottom ends of the left and right rocker arms respectively via Y-type connectors 15. Before the cleaning operation begins, the movable end of the electric cylinder 13 is in an extended state, at which time the electric roller brush 11 is away from the conveying plane of the vibrating screen 1. When the cleaning operation begins, the movable end of the electric cylinder 13 retracts to drive the rocker arm 12 to move downward around the circular hole II via the Y-joint 15. This, in turn, drives the power shaft 8, which is keyed to the rocker arm 12, to rotate counterclockwise. The rotation of the power shaft 8 drives the roller brush arm 10, which is keyed to it, to move downward around the power shaft 8. This causes the electric roller brush 11, located at the bottom end of the roller brush arm 10, to move towards the conveying plane of the vibrating screen 1. When the plane is close, the electric roller brush 11 is energized to clean the residual tobacco leaves in the vibrating screen 1. When the cleaning work is finished, the movable end of the electric cylinder 13 extends to drive the rocker arm 12 to move upward around the circular hole II through the Y-type connector 15. This drives the power shaft 8, which is keyed to the rocker arm 12, to rotate clockwise. The rotation of the power shaft 8 drives the roller brush arm 10, which is keyed to it, to move upward around the power shaft 8. This causes the electric roller brush 11 at the bottom of the roller brush arm 10 to move away from the conveying plane of the vibrating screen 1, thus completing the cleaning work.

[0020] In this embodiment, the synchronous belt slide rail 16 has the function of driving the cleaning mechanism to move forward and backward to clean the entire conveying plane of the vibrating screen 1. The synchronous belt slide rail 16 is horizontally connected to the top of the slide rail support 4 through a mounting plate. The synchronous belt slide rail 16 is provided with a slider. The bottom end of the cleaning bracket is connected to the upper end face of the slider through a base plate. The slider can slide in the extending direction of the synchronous belt slide rail 16, so that the cleaning mechanism can be driven to move forward and backward above the vibrating screen 1 through the cleaning bracket connected to the slider, thereby enabling the cleaning mechanism to clean the conveying plane of the vibrating screen 1 while moving. The driving component has the function of driving the synchronous belt slide rail 16 to move forward and backward through the slider. The driving shaft includes a transmission shaft I19 and a drive shaft I19. The structure is connected in sequence by an expansion sleeve coupling 20, a connecting shaft 21, a plum blossom coupling II 22, and a transmission shaft II 23. The transmission shaft I 19 is connected to a synchronous pulley at one end of the synchronous belt slide rail 16 located on the left side of the vibrating screen 1, and the transmission shaft II 23 is connected to a synchronous pulley at one end of the synchronous belt slide rail 16 located on the right side of the vibrating screen 1. The motor 17 is a stepper motor with a reducer. When the motor 17 is energized, it can drive the transmission shaft I 19, the expansion sleeve coupling 20, the connecting shaft 21, the plum blossom coupling II 22, and the transmission shaft II 23 to rotate in sequence through the plum blossom coupling I 18. This drives the synchronous belt slide rail 16 to move, thereby further driving the cleaning mechanism to move forward and backward above the vibrating screen 1. Specifically, there are two synchronous belt slide rails 16, namely a left synchronous belt slide rail and a right synchronous belt slide rail. The surface of the left synchronous belt slide rail is provided with a left slider, and the surface of the right synchronous belt slide rail is provided with a right slider. The left and right columns of the cleaning bracket are connected to the upper surfaces of the left and right sliders respectively through base plates welded to their bottom ends. The drive shaft I 19 is connected to the synchronous pulley at the end of the left synchronous belt slide rail, and the drive shaft II 23 is connected to the synchronous pulley at the end of the right synchronous belt slide rail. The motor 17 is energized to operate, and the output end of the motor 17 is connected to the... Flower coupling I18 drives transmission shaft I19 to move. Transmission shaft I19 moves to drive the left synchronous belt slide rail. At the same time, transmission shaft I19 drives connecting shaft 21 through expansion sleeve coupling 20. Then, through flower coupling II22 connected to connecting shaft 21, transmission shaft II23 is driven to move. Transmission shaft II23 moves to drive the right synchronous belt slide rail and the left synchronous belt slide rail to move simultaneously. Thus, the left slider and the right slider move synchronously on the left synchronous belt slide rail and the right synchronous belt slide rail, respectively. This drives the cleaning mechanism to move forward and backward above the vibrating screen 1 through the cleaning bracket.

[0021] In this embodiment, the cable chain groove 24 is horizontally arranged on the side end face of the synchronous belt slide rail 16 located on the left side of the vibrating screen 1, providing an installation track and protective space for the cable cable chain 25. The cable cable chain 25 can be flexibly bent in the cable chain groove 24. The inside of the cable cable chain 25 is provided with a cavity for storing and protecting the wires, air pipes and other cables connecting the cleaning mechanism and external equipment, so as to prevent the cables from getting tangled, pulled or worn during the movement of the cleaning mechanism with the moving mechanism, effectively ensuring the safety and service life of the cables during the operation of the equipment. One end of the cable chain bracket 26 is connected to the cable cable chain 25, and the other end of the cable chain bracket 26 is connected to the side end face of the cleaning bracket, so that the cable cable chain 25 can move synchronously with the cleaning mechanism, ensuring that the cables are always in an orderly stored and protected state during the movement of the cleaning mechanism. Specifically, the cable chain groove 24 is connected to the upper end face of the mounting plate and is horizontally set on the outer side of the left synchronous belt slide rail. The cable chain 25 is placed inside the cable chain groove 24. The first end of the cable chain 25 is connected to the side end face of the left column of the cleaning bracket through the cable chain bracket 26, and the end of the cable chain 25 is placed at the tail of the cable chain groove 24.

[0022] In this embodiment, the photoelectric sensor 27 has the function of real-time detection of the position of the cleaning mechanism. Two photoelectric sensors 27 are provided: photoelectric sensor I and photoelectric sensor II. Photoelectric sensor I is fixed to the beginning end of the synchronous belt slide rail 16 located on the right side of the vibrating screen 1 by bolts through photoelectric bracket I, and the position of photoelectric sensor I is directly opposite the position where the cleaning mechanism stops at the beginning end of the synchronous belt slide rail 16. Photoelectric sensor II is fixed to the end end of the synchronous belt slide rail 16 located on the right side of the vibrating screen 1 by bolts through photoelectric bracket II, and the position of photoelectric sensor II is directly opposite the position where the cleaning mechanism stops at the end of the synchronous belt slide rail 16. Photoelectric sensor I and photoelectric sensor II are at the same horizontal height. Specifically, initially, the cleaning mechanism is stationary at the beginning of the synchronous belt slide rail 16. During cleaning, the motor 17 is energized and activated. The motor 17 drives the cleaning mechanism to move towards the rear end of the vibrating screen 1 via the synchronous belt slide rail 16 until the photoelectric sensor II at the end of the synchronous belt slide rail 16 detects that the cleaning mechanism has reached the end of the synchronous belt slide rail 16, at which point the motor 17 stops. At this time, the cleaning mechanism is located at the rear end of the vibrating screen 1. After the cleaning mechanism is controlled to approach the conveying plane of the vibrating screen 1 and operate for a period of time, the motor 17 reverses to drive the cleaning mechanism towards the front end of the vibrating screen 1 via the synchronous belt slide rail 16 until the photoelectric sensor I at the beginning of the synchronous belt slide rail 16 detects that the cleaning mechanism has reached the beginning of the synchronous belt slide rail 16, at which point the motor 17 stops, thus completing one cleaning operation.

[0023] In this embodiment, an electrical control cabinet 28 is provided on the outer side of the vertical support frame. The electrical control cabinet 28 has an inner cavity and a panel. A PLC controller is provided in the inner cavity of the electrical control cabinet 28. The PLC controller is electrically connected to the electric roller brush 11, the electric cylinder 13, the motor 17, and the photoelectric sensor 27. The PLC controller can control the rotation of the electric roller brush 11, the extension and retraction of the electric cylinder 13, the start and stop and forward and reverse rotation of the motor 17, and the operation and feedback of the photoelectric sensor 27. The PLC controller is a Siemens S7-1200 PLC controller. It should be noted that this application does not improve the programmable program of the Siemens S7-1200 PLC controller, but only uses its existing control program and principle to realize the data calculation and comparison function. For the control program and principle involved, please refer to the product manual of the controller or existing technical materials. The control cabinet 28 has a start button and a stop button on its panel surface. Both the start button and the stop button are reset buttons. Both the start button and the stop button are electrically connected to the PLC controller. Pressing the start button will start the control system so that the PLC controller can control the operation of each electrically connected component. Pressing the stop button will end the entire working process. The PLC controller is powered by an external power supply.

[0024] like Figure 11 As shown, in conjunction with the above, the specific steps of this utility model include: Step S1: Set parameters The number of times N is preset for the cleaning machine to clean the conveying plane of the vibrating screen 1. That is, the cleaning mechanism moves from the front end of the vibrating screen 1 to the rear end of the vibrating screen 1, so that the electric roller brush 11 in the cleaning mechanism approaches the conveying plane of the vibrating screen 1 and moves, starting to clean from the rear conveying plane of the vibrating screen 1 to the front conveying plane of the vibrating screen 1, and finally the electric roller brush 11 in the cleaning mechanism moves away from the conveying plane of the vibrating screen 1 and stops moving, which is one cleaning. At the same time, the contraction / extension time T of the electric cylinder 13 is set, which is the time for the electric roller brush 11 to approach / move away from the conveying plane of the vibrating screen 1. Step S2: Preparation for Cleaning When cleaning is required on the conveying surface of the vibrating screen 1, the motor 17 is started and rotated forward. The output end of the motor 17 can drive the drive shaft to rotate through the plum blossom coupling I 18, so that the drive shaft drives the synchronous belt slide rails 16 symmetrically arranged on the left and right sides of the vibrating screen 1 to move simultaneously. This, in turn, drives the cleaning mechanism set above the traveling mechanism to move from the front end of the vibrating screen 1 to the rear end of the vibrating screen 1. When the cleaning mechanism moves to the rear end of the vibrating screen 1, the photoelectric sensor 27 located at the end of the synchronous belt slide rail 16 detects that the cleaning mechanism has reached the rear end of the vibrating screen 1 and sends a feedback signal, and the motor 17 stops. After stopping operation, the electric cylinder 13 retracts according to the set time T. The retraction action of the electric cylinder 13 drives the power shaft 8 to rotate through the rocker arm 12, which in turn causes the power shaft 8 to drive the electric roller brush 11 to descend through the roller brush swing arms 10 symmetrically arranged on its surface. At the same time, the electric roller brush 11 is energized and begins to rotate, and the linear velocity direction of the bottom edge of the electric roller brush 11 is towards the front end of the vibrating screen 1, preparing for the subsequent cleaning of the residual tobacco leaves on the vibrating screen 1. During this process, the cable chain bracket 26 moves synchronously with the cleaning mechanism and drives the cable chain 25 to bend in the cable chain groove 24. Step S3: Cleaning Operation According to step S2, after time T, the electric roller brush 11 descends to the appropriate cleaning position, that is, the lower end of the electric roller brush 11 is in close contact with the conveying plane of the vibrating screen 1. The motor 17 starts to reverse, driving the synchronous belt slide rail 16 to move in the opposite direction. Under the drive of the synchronous belt slide rail 16, the cleaning mechanism runs from the end of the vibrating screen 1 to the front end of the vibrating screen 1 and cleans the conveying plane of the vibrating screen 1 until the photoelectric sensor 27 at the beginning of the synchronous belt slide rail 16 detects that the cleaning mechanism has reached the front end of the vibrating screen 1 and sends a feedback signal. The motor 17 stops running. Then, the electric cylinder 13 extends according to the set time T. The extension action of the electric cylinder 13 drives the power shaft 8 to rotate through the rocker arm 12, which in turn causes the power shaft 8 to drive the electric roller brush 11 to rise through the roller brush swing arms 10 symmetrically arranged on its surface. At the same time, the electric roller brush 11 stops rotating, completing one cleaning operation. At this time, the cleaning count increases by one. During this process, the cable drag chain 25 continues to operate. Step S4: Determine the number of cleaning cycles The actual number of cleanings counted in real time in step S3 is compared with the preset number of cleanings N for vibrating screen 1 in step S1. If the current actual number of cleanings has not reached the preset number of cleanings N, the operation of steps S2 and S3 is repeated to continue cleaning the conveying plane of vibrating screen 1. When the actual number of cleanings reaches the preset number of cleanings N, the equipment stops running and the cleaning work of vibrating screen 1 is completed.

[0025] In this embodiment, in step S1, the T value can be adjusted according to the time required for the electric roller brush 11 to descend to the appropriate cleaning position, so as to ensure that the electric roller brush 11 can reach the cleaning position accurately and in a timely manner.
