Description

Technical Field

[0001] The present application relates to the field of automation control technology, and in particular to a belt line automatic cleaning scraper device and control system. Background Art

[0002] In the production of lithium battery materials, conveying filter cake is a critical process. Belt scrapers play a crucial role in this process, separating the filter cake from the belt as it is conveyed from the filter press to the next process. However, due to the physical properties of filter cake, a large amount of material often remains on the scraper after each batch of production. If not promptly cleaned, this residual material will clump on the scraper, resulting in material waste and affecting scraping effectiveness.

[0003] Currently, cleaning residual material from scrapers mainly relies on manual operation, using material removal tools. This method is not only time-consuming and labor-intensive, but also easily introduces foreign matter to contaminate the product and may even damage the scraper.

[0004] Existing solutions to these problems have not been able to effectively improve production efficiency, reduce the need for manual cleaning, or avoid product contamination and scraper damage. Summary of the Invention

[0005] In view of the technical problems existing in the background technology, the present application provides a belt line automatic cleaning scraper device and control system. Through automatic control technology, the scraper automatically flips after each batch of material is transported. Under the action of centrifugal inertia composed of spring force and gravity, the material is separated to realize the function of automatic cleaning scraper.

[0006] In a first aspect, an embodiment of the present application provides a belt line automatic cleaning scraper device, comprising a scraper assembly, a rotary power assembly, and a latch assembly: The scraper assembly includes a transmission main shaft, a scraper and a tongue. The scraper and the tongue are sleeved on the periphery of the transmission main shaft. The transmission main shaft drives the scraper and the tongue to reciprocate between the working position and the cleaning position. A rotary power assembly comprising a rotary spring, a power cylinder and a first transmission assembly, wherein the rotary spring is sleeved on the periphery of the transmission main shaft, and the power cylinder is rotationally connected to the transmission main shaft through the first transmission assembly; The latch assembly includes a thrust cylinder, a latch and a base. The base is spaced apart from the transmission main shaft and interferes with the movement path of the scraper. When the tongue is in the working position, the tongue is located between the latch and the base. The thrust cylinder faces the latch and drives the latch to move in a direction away from or close to the tongue.

[0007] In this embodiment, the mechanical structure of the device includes at least three major assemblies: a scraper assembly, a rotating power assembly, and a latch assembly.

[0008] Scraper Assembly: The scraper is bolted to the drive shaft, with latches welded to each end. At least two stoppers are positioned along the latches' path to limit the scraper's movement at both endpoints. The scraper is positioned in either a working or cleaning position. The rotation of the drive shaft drives the scraper and latches back and forth between the working and cleaning positions. In the working position, the scraper cleans debris from the belt line; in the cleaning position, the scraper is removed from the belt line to clean any residue.

[0009] Rotational power assembly: The rotational spring provides rotational power for the transmission main shaft, and the power cylinder is rotationally connected to the transmission main shaft through the first transmission assembly to realize automatic rotation of the transmission main shaft.

[0010] Latch Assembly: When the latch is in the working position, it lies between the latch and the base, which act as a retaining force for the latch. At this point, the scraper engages the belt line, clearing material from the belt. The thrust cylinder drives the latch toward or away from the latch, unlocking and locking the latch.

[0011] This device automatically rotates the scraper blade through a rotary powertrain, improving production efficiency and reducing manual operation. A latch assembly locks and unlocks the latch, ensuring stable switching between the working and cleaning positions. Automatically cleaning the belt line reduces wear caused by debris accumulation, extending its service life and reducing energy consumption. The automatic scraper cleaning device ensures the belt line remains clean at all times, reducing downtime caused by debris and improving the continuous operation of the production line.

[0012] In some embodiments of the present application, a bearing seat is further included, and the transmission main shaft passes through the bearing seat.

[0013] In this embodiment, a rotation spring and a bearing seat are installed at both ends of the scraper main shaft respectively; the rotation spring provides rotational force, and the bearing seat ensures the flexibility of the scraper main shaft rotation, supports and fixes the transmission main shaft, and ensures that the scraper's rotation movement is smooth and reliable.

[0014] The drive shaft passes through the bearing housing, allowing the scraper blade to rotate around the drive shaft. Bearings within the housing reduce friction, ensuring smooth rotation of the drive shaft and stable operation of the scraper blade. During the cleaning process, the scraper blade quickly flips under the action of a spring, and the bearing housing ensures the accuracy and reliability of this flipping action.

[0015] The addition of a bearing seat improves the stability of the drive system and reduces failures caused by vibration or eccentric loads. The bearing seat can significantly reduce friction during rotation, reduce energy loss, and increase the service life of the equipment. The precise installation of the bearing seat ensures the accuracy of the scraper rotation, which helps to improve the cleaning effect.

[0016] In some embodiments of the present application, a limit block is further included. The limit block is spaced apart from the transmission main shaft and interferes with the movement path of the scraper. When the tongue is in the cleaning position, the limit block abuts against the tongue.

[0017] In this embodiment, the function of the limit block is to ensure that the scraper can accurately stop at a predetermined position during the cleaning process, thereby completing the cleaning action.

[0018] The stop block is fixed to the device's frame, spaced from the drive spindle, and located in the scraper's path. When the automatic cleaning process is activated, the scraper begins to rotate under the action of the power cylinder and spring to achieve the cleaning purpose. When the scraper rotates to the cleaning position, the latch rotates with the scraper. When the latch rotates to the position where it contacts the stop block (the cleaning position), the stop block abuts the latch, preventing it from rotating further. This abutment quickly stops the scraper, ensuring that the material on the scraper is effectively removed by centrifugal force. After cleaning is completed, the scraper returns to the working position and is ready for the next cleaning.

[0019] The stop block ensures that the scraper stops precisely at the predetermined position during the cleaning process, improving cleaning accuracy. The control of the stop block avoids equipment damage or safety accidents caused by excessive rotation of the scraper.

[0020] In some embodiments of the present application, when the rotation spring is located at an initial position, the scraper and the latch are located at a cleaning position.

[0021] In this embodiment, the initial position is that the rotation spring remains relaxed in an unstressed state, and the scraper and the latch are in the cleaning position.

[0022] When the control system receives the working signal, the power cylinder starts to move, pushing the transmission main shaft, causing the rotation spring to be tightened. At this time, the scraper is in the "vertical" working position, the rotation springs at both ends are tightened, and the latch is automatically fixed.

[0023] Start cleaning: When the latch is released, the scraper automatically rotates under the force of the spring. As the rotation occurs, the energy stored in the spring is released, pushing the scraper to rotate rapidly and the latch moves accordingly.

[0024] Stop rotation: until the tongue touches the limit block to prevent further rotation, the scraper rotates to the limit position and stops instantly. The material sticking to the scraper is separated by the inertia of centrifugal force.

[0025] After cleaning is completed, return the scraper to its working position, tighten the rotating spring again, and prepare for the next cleaning.

[0026] In some embodiments of the present application, the first transmission assembly includes a linear guide rail and a gear slider, the gear slider is meshed with the transmission main shaft, the linear guide rail is located on the side of the gear slider away from the transmission main shaft and is meshed with the gear slider, and the power cylinder is transmission-connected to the gear slider.

[0027] In this embodiment, the spur gear installed on the gear slider drives the slider from one end to the other through the spur gear transmission, and the scraper returns to the "vertical" working position again through the horizontal thrust of the power cylinder.

[0028] The linear guide rail and the power cylinder are jointly arranged on the base plate, which is connected to the frame of the device. A gear slider is stacked on the linear guide rail, and the upper surface of the gear slider is meshed with the transmission main shaft. The output shaft of the power cylinder is transmission-connected to the gear slider, driving the gear slider to move linearly along the extension direction of the linear guide rail.

[0029] When the power cylinder is activated, it pushes the gear slider along the linear guide through the drive connection. The linear guide meshes with the gear slider, and the spur gear on the gear slider meshes with the gear on the drive spindle. As the gear slider moves along the linear guide, it drives the connected drive spindle, which also rotates. As the power cylinder pushes the gear slider from one end of the linear guide to the other, the scraper returns from the cleaning position to the "vertical" working position, ready for the next cleaning or work cycle.

[0030] The combination of linear guides and gear sliders provides precise linear motion, enabling more accurate control of the scraper's position. The spur gears are highly efficient, effectively converting the thrust of the power cylinder into the scraper's rotational motion. Reduced friction: The linear guide design reduces friction, lowers energy loss, and improves transmission efficiency.

[0031] In some embodiments of the present application, the first transmission assembly includes at least two proximity sensors, and the two proximity sensors are respectively located at two ends of the linear guide rail.

[0032] In this embodiment, the proximity sensor is a sensor that can detect the presence of an object without physical contact and can be used to detect the position or distance of an object. Two proximity sensors are installed at both ends of the linear guide rail to monitor the position of the gear slider. When the gear slider moves to one end of the linear guide rail, the corresponding proximity sensor will be triggered and send a signal to the control system. After receiving the signal, the control system can perform corresponding actions, such as activating a power cylinder to move the gear slider, or stop the movement to complete a work cycle. In this way, the proximity sensor ensures that the gear slider moves accurately within a predetermined range and does not exceed the limits of the linear guide rail.

[0033] Proximity sensors provide precise position feedback, ensuring the gear slider stops or changes direction at the correct location. The use of proximity sensors increases the automation level of transmission components and reduces the need for manual intervention. By monitoring the position of the gear slider, equipment damage caused by overtravel can be prevented.

[0034] In some embodiments of the present application, a return spring is further included, and both ends of the return spring are respectively connected to the latch and the base.

[0035] In this embodiment, the return spring is an elastic element that can return to its original shape after the external force disappears. When the tongue and scraper are in the working position and the thrust cylinder is not activated, the function of the return spring is to keep the latch in a locked state and limit the position of the tongue and scraper. When it is necessary to clean the fixed scraper, the thrust cylinder is activated, overcoming the elastic force of the return spring, pushing the latch away from the tongue, thereby unlocking the tongue and scraper. The scraper is quickly rotated from the working position to the cleaning position under the elastic force of the rotation spring, completing a cleaning cycle. After the scraper completes cleaning, it returns to the working position to continue cleaning the belt line. Once the thrust cylinder releases pressure, the return spring will pull the latch back, returning the tongue and scraper to the locked position.

[0036] A return spring ensures the latch automatically returns to its initial position when not in use, eliminating the need for additional controls or manipulation. This reduces the need for complex mechanical structures and controls, simplifying the overall design. It also helps reduce energy consumption in the power cylinder when the scraper is not being held.

[0037] In a second aspect, an embodiment of the present application provides a control system, comprising a control element and an automatic belt line cleaning scraper device as described in any embodiment of the first aspect.

[0038] In this embodiment, the control system includes control components, such as a programmable logic controller (PLC), relays, and sensors, which are signal-connected to the power cylinder and thrust cylinder of the automatic belt line scraper cleaning device. The control components receive signals from sensors, such as proximity sensors and timers, that indicate the current status of the scraper device (e.g., scraper position, start and end of a cleaning cycle, etc.).

[0039] The control system automates the operation of the scraper mechanism, reducing manual intervention and improving production efficiency. Through signal connections, the control system precisely controls the movement of the power and thrust cylinders, ensuring the scraper mechanism operates according to pre-programmed procedures. The control system can adjust the cleaning cycle and operation to suit varying production requirements and work environments. It also monitors equipment status to prevent misoperation and damage, improving work safety.

[0040] In some embodiments of the present application, the control element includes a first timer and a second timer, the first timer is connected to the thrust cylinder signal, and the second timer is connected to the power cylinder signal.

[0041] In this embodiment, a first timer is connected to the thrust cylinder signal to control the thrust cylinder's actuation timing. When the control system initiates the operating program, the first timer begins counting. After the first timer reaches a preset time, the first timer sends a signal to the thrust cylinder, causing it to actuate, pushing the latch out of its locked position, thereby releasing the scraper and allowing it to rotate for cleaning.

[0042] A second timer, connected to the power cylinder's signal, controls its operating time. When the scraper blade rotates to a certain angle and the gear slider triggers one of the proximity sensors, the second timer begins. When the second timer expires, it sends a signal to the power cylinder, triggering it to move the gear slider along the linear guide toward the other proximity sensor. This, in turn, rotates the drive spindle and scraper blade, returning them to their working position.

[0043] The first and second timers precisely control the timing of the thrust and power cylinders, ensuring that the scraper mechanism operates according to the pre-set schedule. The use of timers ensures a more regular and efficient cleaning cycle, reducing unnecessary waiting time. Timers can also simplify control system programming, allowing complex action sequences to be controlled by setting time parameters. Adjusting the timer settings allows the scraper mechanism's duty cycle to be easily altered to suit varying production requirements.

[0044] In some embodiments of the present application, the control element includes a switch and a counter, the counter is connected to the proximity sensor signal of the belt line automatic cleaning scraper device, and the switch is connected to the counter signal.

[0045] In this embodiment, when the control system receives the signal to begin cleaning, it activates the thrust cylinder, pushing the latch out of its locked position, allowing the scraper to rotate freely and complete the cleaning cycle. After the drive shaft rotates, the gear slider triggers a proximity sensor. The control system then activates the power cylinder, which, according to a pre-set program, moves the gear slider along a linear guide toward another proximity sensor, thereby rotating the drive shaft and scraper. At the end of the cleaning cycle, the gear slider triggers another proximity sensor, causing the control system to release the thrust cylinder, and a return spring to push the latch back into its locked position, securing the scraper.

[0046] When each batch of materials on the belt line is completed, the system receives a signal and automatically starts the cleaning process.

[0047] After starting, the first timer starts timing. When the preset time is reached, the first timer sends a signal to enable the thrust cylinder to be energized and actuated.

[0048] After the thrust cylinder is actuated, the latch is pushed away from the locked position, releasing the scraper so that it can be quickly flipped under the action of the spring.

[0049] The scraper turns over under the action of the spring force until the tongue is instantly blocked by the limit block and stops turning over.

[0050] The gear installed on the transmission main shaft rotates as the scraper flips, driving the gear slider to move.

[0051] When the gear slider moves to one end of the linear slide, one of the proximity sensors is triggered, starting the power cylinder and the second timer.

[0052] The power cylinder pushes the gear slider to move to the other end of the linear slide until another proximity sensor is triggered, the thrust cylinder unloads the force, and the tongue is stuck by the pin.

[0053] The second timer starts timing, and when the time is up, the power cylinder retracts.

[0054] The second proximity sensor counts once and starts the first timer, preparing for the next cleaning cycle. This process repeats until the set number of cycles is reached.

[0055] Stop cleaning: When the number of cycles reaches the set number, the device stops automatically and the cleaning is completed.

[0056] The entire cleaning process requires no human intervention, achieving a high degree of automation and saving labor costs. Timer control ensures precise timing for each action, improving cleaning efficiency. Adjustable timers can be adjusted to accommodate varying production rhythms and cleaning needs. The automatic control system prevents equipment damage and safety incidents caused by improper manual operation.

[0057] This device automatically cleans the scraper blade using a spring, cylinder, rack and pinion, and sensor. The scraper rotates automatically, and a latch and stop block momentarily stop it. Material adhering to the scraper separates under inertia and returns to the storage bin. This saves both labor and materials, eliminates quality risks caused by foreign matter introduced during scraper cleaning, and prevents scratches and damage to the scraper surface.

[0070] In view of the technical problems existing in the background technology, the present application provides a belt line automatic cleaning scraper device and control system. Through automatic control technology, the scraper automatically flips after each batch of material is transported. Under the action of centrifugal inertia composed of spring force and gravity, the material is separated to realize the function of automatic cleaning scraper.

[0071] In the first aspect, the embodiment of the present application provides a belt line automatic cleaning scraper device, such as Figures 1-4 As shown, Figure 1 This is a schematic diagram of the working position structure of a belt line automatic cleaning scraper device in an embodiment of the present application; Figure 2 This is a schematic diagram of the cleaning position structure of a belt line automatic cleaning scraper device in an embodiment of the present application; Figures 3A to 3C Six views of an automatic scraper device for cleaning a belt line according to an embodiment of the present application; Figure 4 This is an enlarged schematic diagram of an automatic belt line cleaning scraper device in an embodiment of the present application. Figure 3A is the right view, Figure 3B For the main view, Figure 3C This is the left view.

[0072] A belt line automatic cleaning scraper device includes a scraper assembly 1, a rotating power assembly 2, and a latch assembly 3: The scraper assembly 1 includes a transmission main shaft 11, a scraper 12 and a tongue 13. The scraper 12 and the tongue 13 are sleeved on the periphery of the transmission main shaft 11. The transmission main shaft 11 drives the scraper 12 and the tongue 13 to reciprocate between the working position and the cleaning position. The rotary power assembly 2 includes a rotary spring 21, a power cylinder 22, and a first transmission assembly. The rotary spring 21 is sleeved on the periphery of the transmission main shaft 11, and the power cylinder 22 is rotationally connected to the transmission main shaft 11 through the first transmission assembly. The latch assembly 3 includes a thrust cylinder 31, a latch 32 and a base 33. The base 33 is spaced apart from the transmission main shaft 11 and interferes with the movement path of the scraper 12. When the tongue 13 is in the working position, the tongue 13 is located between the latch 32 and the base 33. The thrust cylinder 31 is directed toward the latch 32, and the thrust cylinder 31 drives the latch 32 to move in a direction away from or close to the tongue 13.

[0073] In this embodiment, the mechanical structure of the device includes at least three major assemblies: a scraper assembly 1 , a rotating power assembly 2 and a latch assembly 3 .

[0074] Scraper assembly 1: The scraper 12 is fixed to the transmission main shaft 11 by bolts, and the tongue 13 is welded to both ends of the transmission main shaft 11. By providing at least two limiting structures on the movement path of the tongue 13, the two end points of the movement path of the scraper 12 can be limited. The scraper 12 is in the working position and the cleaning position at the two end points respectively. The transmission main shaft 11 rotates, driving the scraper 12 and the tongue 13 to reciprocate between the working position and the cleaning position. When in the working position, the scraper 12 is used to clean debris on the belt line 4; when in the cleaning position, the scraper 12 leaves the belt line 4 to clean the residue on the scraper 12.

[0075] Rotational power assembly 2: The rotational spring 21 provides rotational power for the transmission main shaft 11 , and the power cylinder 22 is rotationally connected to the transmission main shaft 11 through the first transmission assembly to realize automatic rotation of the transmission main shaft 11 .

[0076] Latch assembly 3: When the latch 13 is in the working position, it lies between the latch 32 and the base 33, which act as a retaining force for the latch 13. At this point, the scraper 12 engages the belt line 4, cleaning the material on it. The thrust cylinder 31 drives the latch 32 away from or toward the latch 13, unlocking and locking the latch 13.

[0077] This device automatically rotates the scraper 12 through the rotary power assembly 2, improving production efficiency and reducing manual operation. A latch assembly 3 locks and unlocks the latch 13, ensuring stable switching of the scraper 12 between the working and cleaning positions. This automatic cleaning of the belt line 4 reduces wear caused by debris accumulation, extending its service life and reducing energy consumption. The automatic scraper cleaning device ensures that the belt line 4 remains clean at all times, reducing downtime caused by debris and improving the continuous operation of the production line.

[0078] In some embodiments of the present application, a bearing seat is further included, and the transmission main shaft 11 passes through the bearing seat.

[0079] In this embodiment, a rotation spring 21 and a bearing seat are respectively installed at both ends of the scraper 12 main shaft; the function of the rotation spring 21 is to provide rotational force, and the function of the bearing seat is to ensure the flexibility of the rotation of the scraper 12 main shaft, support and fix the transmission main shaft 11, and ensure that the rotation movement of the scraper 12 is smooth and reliable.

[0080] The drive shaft 11 passes through the bearing housing, allowing the scraper 12 to rotate around the drive shaft 11. The bearings within the housing reduce friction, ensuring smooth rotation of the drive shaft 11 while maintaining the stable operation of the scraper 12. During the cleaning process, the scraper 12 quickly flips due to the spring action, and the bearing housing ensures the precision and reliability of this flipping action.

[0081] The addition of a bearing seat improves the stability of the drive system and reduces failures caused by vibration or eccentric loads. The bearing seat significantly reduces friction during rotation, reducing energy loss and increasing the life of the equipment. Precise installation of the bearing seat ensures precise rotation of the scraper 12, helping to improve cleaning results.

[0082] In some embodiments of the present application, a limit block 34 is further included. The limit block 34 is spaced apart from the transmission main shaft 11 and interferes with the movement path of the scraper 12. When the tongue 13 is in the cleaning position, the limit block 34 abuts against the tongue 13.

[0083] In this embodiment, the function of the stop block 34 is to ensure that the scraper 12 can accurately stop at a predetermined position during the cleaning process, thereby completing the cleaning action.

[0084] The limit block 34 is fixed to the frame of the device, spaced apart from the transmission main shaft 11, and located on the movement path of the scraper 12. When the automatic cleaning program is started, the scraper 12 begins to rotate under the action of the power cylinder 22 and the spring to achieve the purpose of cleaning. When the scraper 12 rotates to the cleaning position, the tongue 13 will rotate with the scraper 12. When the tongue 13 rotates to the position in contact with the limit block 34, that is, the cleaning position, the limit block 34 will abut against the tongue 13, preventing the tongue 13 from continuing to rotate. This abutment action causes the scraper 12 to stop rotating quickly, ensuring that the material on the scraper 12 is effectively cleaned under the action of centrifugal force. After cleaning is completed, the scraper 12 returns to the working position and prepares for the next cleaning.

[0085] The stop block 34 ensures that the scraper 12 can accurately stop at a predetermined position during the cleaning process, thereby improving the accuracy of cleaning. Through the control of the stop block 34, damage to the equipment or safety accidents that may be caused by excessive rotation of the scraper 12 are avoided.

[0086] In some embodiments of the present application, when the rotation spring 21 is located at the initial position, the scraper 12 and the latch 13 are located at the cleaning position.

[0087] In this embodiment, in the initial position, the rotation spring 21 remains relaxed in an unstressed state, and the scraper 12 and the latch 13 are in the cleaning position.

[0088] When the control system receives the working signal, the power cylinder 22 starts to move, pushing the transmission main shaft 11, so that the rotation spring 21 is tightened. At this time, the scraper 12 is in the "vertical" working position, the rotation springs 21 at both ends are tightened, and the latch 32 is automatically fixed.

[0089] Start cleaning: When the latch 32 is released, the scraper 12 automatically rotates under the force of the spring. As the energy stored in the rotating spring 21 is released, the scraper 12 is pushed to rotate rapidly, and the tongue 13 moves accordingly.

[0090] Stop rotating: until the tongue 13 touches the limit block 34 to prevent further rotation, the scraper 12 rotates to the limit position and stops instantly, and the material sticking to the scraper 12 is separated out under the action of centrifugal inertia.

[0091] After cleaning is completed, the scraper 12 is restored to the working position, and the rotation spring 21 is tightened again to prepare for the next cleaning.

[0092] In some embodiments of the present application, the first transmission assembly includes a linear guide rail 23 and a gear slider 24, the gear slider 24 is meshed and connected to the transmission main shaft 11, the linear guide rail 23 is located on the side of the gear slider 24 away from the transmission main shaft 11 and is meshed and connected to the gear slider 24, and the power cylinder 22 is transmission-connected to the gear slider 24.

[0093] In this embodiment, through the spur gear transmission, the spur gear installed on the gear slider 24 drives the slider to move from one end to the other end, and the horizontal thrust of the power cylinder 22 causes the scraper 12 to return to the "vertical" working position again.

[0094] The linear guide rail 23 and the power cylinder 22 are jointly arranged on the base plate, and the base plate is connected to the frame of the device. A gear slider 24 is stacked on the linear guide rail 23. The upper surface of the gear slider 24 is meshed with the transmission main shaft 11. The output shaft of the power cylinder 22 is transmission-connected to the gear slider 24, driving the gear slider 24 to move linearly along the extension direction of the linear guide rail 23.

[0095] When the power cylinder 22 is activated, it pushes the gear slider 24 along the linear guide 23 through a transmission connection. The linear guide 23 meshes with the gear slider 24, and the spur gear on the gear slider 24 meshes with the gear on the drive spindle 11. As the gear slider 24 moves along the linear guide 23, it drives the connected drive spindle 11, which also rotates. As the power cylinder 22 pushes the gear slider 24 from one end of the linear guide 23 to the other, the scraper 12 returns from the cleaning position to the "vertical" working position, ready for the next cleaning or working cycle.

[0096] The combination of the linear guide 23 and the gear slider 24 provides precise linear motion, enabling more accurate position control of the scraper 12. The spur gears offer high transmission efficiency, effectively converting the thrust of the power cylinder 22 into the rotational motion of the scraper 12. Reduced friction: The design of the linear guide 23 reduces friction, lowering energy loss and improving transmission efficiency.

[0097] In some embodiments of the present application, the first transmission assembly includes at least two proximity sensors 25 , and the two proximity sensors 25 are respectively located at two ends of the linear guide rail 23 .

[0098] In this embodiment, the proximity sensor 25 is a sensor that can detect the presence of an object without physical contact and can be used to detect the position or distance of an object. Two proximity sensors 25 are respectively installed at both ends of the linear guide 23 to monitor the position of the gear slider 24. When the gear slider 24 moves to one end of the linear guide 23, the corresponding proximity sensor 25 will be triggered and send a signal to the control system. After receiving the signal, the control system can perform corresponding actions, such as activating the power cylinder 22 to move the gear slider 24, or stop moving to complete a working cycle. In this way, the proximity sensor 25 ensures that the gear slider 24 moves accurately within a predetermined range and does not exceed the limit of the linear guide 23.

[0099] Proximity sensor 25 provides precise position feedback, ensuring that gear slider 24 stops or changes direction at the correct position. The use of proximity sensor 25 increases the automation level of the transmission assembly and reduces the need for manual intervention. By monitoring the position of gear slider 24, equipment damage caused by overtravel can be prevented.

[0100] In some embodiments of the present application, a return spring 35 is further included, and both ends of the return spring 35 are connected to the latch 32 and the base 33 respectively.

[0101] In this embodiment, the return spring 35 is an elastic element that can return to its original shape after the external force disappears. When the tongue 13 and scraper 12 are in the working position and the thrust cylinder 31 is not activated, the function of the return spring 35 is to keep the latch 32 in a locked state, limiting the position of the tongue 13 and scraper 12. When it is necessary to clean the fixed scraper 12, the thrust cylinder 31 is activated, overcoming the elastic force of the return spring 35, pushing the latch 32 away from the tongue 13, thereby unlocking the tongue 13 and scraper 12. The scraper 12 is quickly rotated from the working position to the cleaning position under the elastic force of the rotation spring 21, completing a cleaning operation. After the scraper 12 completes the cleaning, it returns to the working position to continue cleaning the belt line 4. Once the thrust cylinder 31 releases pressure, the return spring 35 will pull the latch 32 back, returning the tongue 13 and scraper 12 to the locked position.

[0102] The return spring 35 ensures that the latch 32 automatically returns to its initial position when not in use, without requiring additional control or operation. The use of the return spring 35 reduces the complexity of the mechanical structure and control requirements, simplifying the overall design. When the scraper 12 is not required to be fixed, the return spring 35 helps reduce the energy consumption of the power cylinder 22.

[0103] In a second aspect, the present application provides a control system, such as Figure 5 As shown, Figure 5 This is a control diagram of a control system in an embodiment of the present application. In the diagram, MP: belt line batch completion signal; SB1: manual push-button start switch; SB2: manual push-button stop switch; KA1: system start intermediate relay; L1: start power indicator light; Q1: first proximity sensor; Q2: second proximity sensor; KT1: first timer; KT2: second timer; KA2: thrust cylinder switch relay; KA3: power cylinder switch relay; C1: counter.

[0104] A control system comprises a control element and a belt line automatic cleaning scraper device as described in any one embodiment of the first aspect.

[0105] In this embodiment, the control system includes control elements, such as a programmable logic controller (PLC), relays, sensors, etc. The control elements receive signals from sensors, such as a proximity sensor 25, a timer, etc., which indicate the current status of the scraper device (such as the position of the scraper 12, the start and end of the cleaning cycle, etc.).

[0106] The control system automates the operation of the scraper mechanism, reducing manual intervention and improving production efficiency. Through signal connections, the control system precisely controls the movement of the power cylinder 22 and thrust cylinder 31, ensuring the scraper mechanism operates according to pre-programmed procedures. The control system can adjust the cleaning cycle and operation to suit varying production requirements and work environments. It also monitors equipment status to prevent misoperation and damage, thereby improving work safety.

[0107] In some embodiments of the present application, the control element includes a first timer and a second timer, the first timer is connected to the thrust cylinder 31 by signal, and the second timer is connected to the power cylinder 22 by signal.

[0108] In this embodiment, a first timer is connected to the thrust cylinder 31 for controlling the duration of its operation. When the control system initiates the operating program, the first timer begins counting. After the first timer reaches a preset time, it sends a signal to the thrust cylinder 31, causing it to actuate, pulling the latch 32 out of its locked position, thereby releasing the scraper 12 and allowing it to rotate for cleaning.

[0109] A second timer is connected to the power cylinder 22 and controls its operation time. When the scraper 12 rotates to a certain angle and the gear slider 24 triggers one of the proximity sensors 25, the second timer begins. When the second timer expires, it sends a signal to the power cylinder 22, causing it to actuate. This pushes the gear slider 24 along the linear guide 23 toward the other proximity sensor 25, thereby rotating the drive spindle 11 and scraper 12 and returning them to their working position.

[0110] The first and second timers precisely control the timing of the action of the thrust cylinder 31 and the power cylinder 22, ensuring that the scraper assembly operates according to the pre-set program. The use of timers makes the cleaning cycle more regular and efficient, reducing unnecessary waiting time. Timers can also simplify control system programming, allowing complex action sequences to be controlled by setting time parameters. By adjusting the timer settings, the scraper assembly's duty cycle can be easily changed to suit different production needs.

[0111] In some embodiments of the present application, the control element includes a switch and a counter, the counter is connected to the proximity sensor 25 signal of the belt line automatic cleaning scraper device, and the switch is connected to the counter signal.

[0112] In this embodiment, when the control system receives a signal to begin cleaning, it activates the thrust cylinder 31, pushing the latch 32 out of its locked position, allowing the scraper 12 to rotate freely, completing the cleaning process. After the transmission spindle 11 rotates, driving the gear slider 24 to trigger a proximity sensor 25, the control system activates the power cylinder 22, which, according to a pre-set program, pushes the gear slider 24 along the linear guide 23 toward another proximity sensor 25, thereby rotating the transmission spindle 11 and scraper 12. At the end of the cleaning cycle, the gear slider 24 triggers another proximity sensor 25, and the control system controls the thrust cylinder 31 to release its force. The return spring 35 then pushes the latch 32 into its locked position, securing the scraper 12.

[0113] When each batch of materials on belt line 4 is transported, the system receives a signal and automatically starts the cleaning process.

[0114] After starting, the first timer starts timing. When the preset time is reached, the first timer sends a signal to enable the thrust cylinder 31 to be powered and activated.

[0115] After the thrust cylinder 31 is actuated, the latch 32 is pushed away from the locked position, releasing the scraper 12 so that it can be quickly flipped under the action of the spring.

[0116] The scraper 12 turns over under the action of the spring force until the latch 13 is instantly blocked by the limit block 34 and stops turning over.

[0117] The gear mounted on the transmission main shaft 11 rotates as the scraper 12 turns over, driving the gear slider 24 to move.

[0118] When the gear slider 24 moves to one end of the linear slide rail, one of the proximity sensors 25 is triggered, and the power cylinder 22 and the second timer are started.

[0119] The power cylinder 22 pushes the gear slider 24 to move toward the other end of the linear slide rail until another proximity sensor 25 is triggered, the thrust cylinder 31 unloads the force, and the latch 13 is stuck by the latch 32.

[0120] The second timer starts timing, and when the time is up, the power cylinder 22 retracts.

[0121] The second proximity sensor 25 counts once and starts the first timer at the same time to prepare for the next cleaning cycle. This process is cyclically carried out until the set number of cycles is reached.

[0122] Stop cleaning: When the number of cycles reaches the set number, the device stops automatically and the cleaning is completed.

[0123] The entire cleaning process requires no human intervention, achieving a high degree of automation and saving labor costs. Timer control ensures precise timing for each action, improving cleaning efficiency. Adjustable timers can be adjusted to accommodate varying production rhythms and cleaning needs. The automatic control system prevents equipment damage and safety incidents caused by improper manual operation.

[0124] This device realizes the function of automatically cleaning the scraper 12 through structures such as springs, cylinders, gear racks, and sensors; the scraper 12 rotates automatically, and the scraper 12 stops moving instantly through the tongue 13 and the limit block 34, and the materials stuck on the scraper 12 are separated under the action of inertia and returned to the storage box, saving manpower and materials; avoiding quality risks caused by foreign matter introduced when the scraper 12 is cleaning; and avoiding scratches and damage on the surface of the scraper 12.
