Description

Technical Field

[0001] This application relates to the field of tobacco manufacturing technology, specifically to a photoelectric sensor shielding cleaning device. Background Technology

[0002] In the tobacco production line, there is a close linkage between the buffer tank, the shredder, and the feeder: when the buffer tank is full, the shredder needs to stop working. At this time, the feeder needs to be stopped by a photoelectric sensor located high up on the feeder. Specifically, the high-position photoelectric sensor needs to be blocked to trigger the feeder's stop command; if it is not blocked in time, the feeder will continue to feed, while the buffer tank is already full, causing material to accumulate on the conveyor belt, vibrating trough, and other equipment between the feeder and the buffer tank until these devices are full, at which point the feeder will stop working due to the subsequent chain reaction. However, there are two significant problems in the current production process: Firstly, the shielding of high-position photoelectric sensors relies on manual operation. Because the sensors are installed at a high position, operators need to spend special time and effort on shielding them, which not only increases labor costs but may also lead to excessive material accumulation due to untimely operation, affecting production efficiency and stability. Secondly, the transparent glass in front of the high-position sensor is easily contaminated. In the tobacco production environment, dust, material debris, and other impurities in the air easily adhere to the surface of the transparent glass. Long-term accumulation will reduce the transparency of the glass, thereby interfering with the detection accuracy of the sensor, potentially causing misjudgments or detection failures, and affecting the normal operation of the entire production line. Cleaning the glass also relies on manual labor, further increasing the tediousness of the operation and the manpower required. Therefore, in response to the problems of high manual dependence, inconvenient operation, and low efficiency of photoelectric sensors in existing tobacco production lines in terms of shielding control and cleaning maintenance, there is an urgent need for a device that can automatically realize the functions of sensor shielding and cleaning, so as to optimize the production process, reduce labor costs and ensure the stable operation of the equipment. Utility Model Content

[0003] The main purpose of this application is to provide a photoelectric sensor shielding and cleaning device, which aims to solve the technical problems of the existing high-position photoelectric sensor in tobacco production line relying on manual shielding operation, which is untimely and inefficient, and the detection glass surface is easily contaminated by dust, affecting the detection accuracy, and cleaning and maintenance also rely on manual labor.

[0004] To achieve the above objectives, this application provides the following technical solution: A photoelectric sensor shielding and cleaning device includes a top plate, a fixing plate on the right side wall of the top plate, a connecting plate on the left side of the bottom wall of the top plate, a first motor on the left side wall of the connecting plate, a round rod locked to the output end of the first motor by a coupling, and the outer wall of the round rod being rotatably connected to the outer wall of the first motor by a first bearing. A round seat is interference-fitted to the outer wall of the round rod, a baffle is provided on the bottom wall of the round seat, and a cleaning mechanism is provided on the right side wall of the round rod.

[0005] Furthermore, the cleaning mechanism includes a connecting seat, a base is provided on the bottom wall of the connecting seat, a second motor is provided on the right side wall of the base, a rotating rod is locked to the output end of the second motor through a coupling, and a brush is provided on the left side wall of the rotating rod.

[0006] Furthermore, the outer wall of the rotating rod is interference-fitted with the inner ring of the second bearing, and the outer ring of the second bearing is fixedly connected to the outer wall of the base through a bearing seat.

[0007] Furthermore, a controller is provided on the outer wall of the top plate and is electrically connected to the first motor and the second motor.

[0008] Furthermore, multiple screw holes are provided through the outer wall of the fixing plate.

[0009] The technical solution provided in this application may include the following beneficial effects: During use, this application utilizes a first motor to drive a rod that moves a baffle, automatically blocking and removing the high-position photoelectric sensor. This solves the problems of inconvenience and untimely manual blocking operations, reduces labor costs, and prevents material accumulation. Simultaneously, a cleaning mechanism at the end of the rod, driven by a second motor, rotates a brush to automatically clean the sensor glass, overcoming the defect of decreased detection accuracy due to dust contamination. The integration of these two automated functions reduces manual intervention, making the start-stop control of the feeder more precise, thereby optimizing the tobacco production line process and improving production efficiency and product quality stability.

[0014] Furthermore, the cleaning mechanism includes a connecting seat 9, a base 10 is provided on the bottom wall of the connecting seat 9, a second motor 11 is provided on the right side wall of the base 10, a rotating rod 12 is locked to the output end of the second motor 11 through a coupling, and a brush 13 is provided on the left side wall of the rotating rod 12. When the second motor 11 is started, the rotating rod 12 is driven to rotate the brush 13, and the rotating brush 13 is used to clean the glass.

[0015] Furthermore, the outer wall of the rotating rod 12 is interference-fitted with the inner ring of the second bearing, and the outer ring of the second bearing is fixedly connected to the outer wall of the base 10 through the bearing seat. The second bearing fixes the rotating rod 12, making it easier for the rotating rod 12 to rotate through the second bearing.

[0016] Furthermore, a controller is provided on the outer wall of the top plate 1 and is electrically connected to the first motor 4 and the second motor 11, so as to facilitate the start and stop control of the first motor 4 and the second motor 11.

[0017] Furthermore, multiple screw holes are provided through the outer wall of the fixing plate 2, which facilitates the installation of this device on the feeding cabinet by welding or bolting through the fixing plate 2.

[0018] 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.

[0019] One specific application of this embodiment is: First, the device is installed on the feeding cabinet using the fixing plate 2. The installation method can be welding or bolting to ensure that the device is stable and located directly above the high-position photoelectric sensor. Then, a suitable round hole is made on the glass in front of the photoelectric sensor, and the round rod 5 is inserted through the round hole so that the baffle 8 and the base 10 are respectively on both sides of the glass, and the brush 13 is in close contact with the glass surface to complete the initial assembly of the device. When it is necessary to block the high-position photoelectric sensor, the first motor 4 is started. The first motor 4 drives the round rod 5 to move downward, which in turn drives the round seat 7, baffle 8, connecting seat 9, base 10, second motor 11, rotating rod 12 and brush 13 to move downward synchronously. When the baffle 8 moves to the low position and is accurately placed in front of the high-position photoelectric sensor, the sensor can be effectively blocked, triggering the feeder to stop feeding. During this process, the second motor 11 is started simultaneously. The second motor 11 drives the rotating rod 12 to rotate, which in turn drives the brush 13 to rotate at high speed. The contact between the brush 13 and the glass surface is used to achieve automatic brushing and cleaning of the glass, ensuring the cleanliness of the glass surface. When there is no need for obstruction, the first motor 4 is reversed and started. The round rod 5 drives the baffle 8, base 10, second motor 11, rotating rod 12 and brush 13 and other structures to move upward and move away from the front of the sensor, thereby removing the obstruction of the high-position photoelectric sensor and restoring it to normal detection operation. In addition, the brush 13 adopts a bolt-fastened detachable installation design, which makes it easy to disassemble and clean or replace it regularly to ensure the stability and continuity of the cleaning effect.
