Description

Technical Field

[0001] This invention relates to the field of conveyor belt transmission equipment, and in particular to a cleaning device for conveyor belt transmission equipment. Background Technology

[0002] With social development and continuous advancements in science and technology, equipment used for conveying workpieces or materials is becoming increasingly diverse. Among these, belt conveyors are commonly used material handling equipment in enterprises. Belt conveyors are widely used in conveying various bulk materials. Typically, belt conveyors with a lifting angle of less than 18° use smooth belts. To keep the belt surface clean, most companies install various types of scraper cleaners at the belt head of the belt conveyor. The scraper cleaners clean the surface of the belt.

[0003] However, in the field of bulk solid waste transportation, due to the complexity of solid waste composition, typical materials such as mixed household waste include not only wet and sticky organic waste, such as leftover food, but also a large amount of plastic film and garbage bags, as well as hard materials such as sand and gravel, metal, and fibrous materials such as clothing, hair, and wool. The complexity of the transported materials poses a great challenge to the cleaning of the belt surface. Conventional scraper cleaners used for belt cleaning have the following problems: During the cleaning process, the scraper blades of the scraper can be pressed tightly against the surface of the belt. However, the belt conveyor drives the belt to rotate back and forth continuously during operation. Therefore, the belt will constantly rub against the scraper blades, causing them to wear down. Gaps will be created between the scraper blades and the belt, making it impossible for the scraper cleaner to clean the belt surface.

[0004] To address this, some scraper cleaners have emerged on the market that use elastic force to drive the scraper to adhere tightly to the belt. These scraper cleaners generally employ the following structure: a fixed base, a swing arm, a compression spring, and a scraper. The fixed base can be fixedly installed on the frame of the belt conveyor. The middle part of the swing arm is rotatably mounted on the lower middle part of the fixed base via a rotating shaft. The swing arm can swing relative to the fixed base around the rotating shaft. One end of the compression spring is connected to the fixed base, and the other end of the compression spring is connected to the rear end of the swing arm. The scraper is installed at the front end of the swing arm. When the fixed base of the scraper cleaner is installed on the frame of the belt conveyor, the scraper at the front end of the swing arm is in close contact with the surface of the belt, and the compression spring is in a compressed state. Therefore, the compression spring can generate elastic force and act on the rear end of the swing arm. When the scraper is worn down by the subsequent belt, the compression spring can drive the swing arm to rotate around the rotating shaft, keeping the scraper in a state of tight pressure on the belt surface. This solves the technical problem of existing scraper cleaners where the scraper cannot clean the belt surface due to the gap between the scraper and the belt.

[0005] While the scraper cleaner described above, which uses elastic force to drive the scraper to adhere tightly to the belt, can solve the problem of the scraper not adhering tightly to the belt due to wear, the compression spring has a limited length. When the scraper is worn too thickly, the compression spring can no longer drive the scraper to adhere tightly to the belt surface. The company can only stop the machine to replace the scraper and readjust the compression spring, which is not only troublesome to operate, but also time-consuming and labor-intensive, greatly reducing the company's production efficiency. Summary of the Invention

[0006] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides a cleaning device for a conveyor belt transmission equipment, which can adjust the magnitude of the elastic force applied to the swing arm by the elastic drive component, thereby enabling the scraper to adhere tightly to the surface of the conveyor belt.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A cleaning device for conveyor belt transmission equipment includes a spring-driven adjustment mechanism and one or more scrapers. The spring-driven adjustment mechanism includes a base assembly, a movable connector, a swing frame, an elastic drive assembly, and a spring-adjusting assembly. The movable connector is movably mounted on the base assembly and can move in a vertical direction towards or away from the base assembly. The swing frame is rotatably mounted on the movable connector via a rotating shaft and has a driving end and a driven end correspondingly located on both sides of the rotating shaft. One end of the elastic drive assembly is connected to or abuts against the base assembly, and the other end of the elastic drive assembly is connected to or abuts against the driving end. The elastic drive assembly can generate an elastic force acting on the driving end. The spring-adjusting assembly is disposed between the base assembly and the movable connector. All scrapers are disposed on the driven end. The spring-adjusting assembly can drive the movable connector to move the swing frame towards or away from the base assembly, thereby adjusting the magnitude of the elastic force applied by the elastic drive assembly to the driving end.

[0009] The beneficial effects of a cleaning device for conveyor belt conveying equipment according to certain embodiments of the present invention are as follows:

The scraper is mounted on the driven end of the swing frame, and an elastic adjustment component is positioned between the base assembly and the movable connecting member. With this structure, when the scraper is excessively worn due to prolonged contact with the conveyor belt, the user can drive the movable connecting member via the elastic adjustment component to move the swing frame closer to the base assembly. The swing frame and the base assembly work together to compress and adjust the elastic drive component, thereby increasing the elastic force applied to the drive end. At this point, the elastic drive component can still apply sufficient elastic force to the drive end of the swing frame, allowing the swing frame to swing around its rotation axis and keeping the scraper in close contact with the conveyor belt. This extends the scraper's service life, reduces the frequency of scraper replacement, lowers maintenance costs, reduces downtime for scraper replacement, and improves production efficiency.

[0028] Figures 1 to 3 This is a schematic diagram of some embodiments of a cleaning device for a conveyor belt conveying equipment according to the present invention.

[0029] Reference Figures 1 to 3 and mainly refer to Figure 2 and Figure 3According to certain embodiments of the present invention, a cleaning device for a conveyor belt transmission equipment (hereinafter referred to as "cleaning device" for ease of description) includes a set of elastic drive adjustment mechanisms 100 and one or more scrapers 200. In this embodiment, the elastic drive adjustment mechanism 100 includes a base assembly, a movable connector 120, a swing frame 130, an elastic drive assembly 140, and an elastic adjustment assembly. The base assembly can be fixedly installed on the main body 400, base frame, or connecting frame of the conveyor belt transmission equipment. The movable connector 120 is movably installed on the base assembly and can move closer to or away from the base assembly in the vertical direction. A rotating shaft 1301 arranged horizontally is provided at the lower part of the base assembly. The middle part of the swing frame 130 is rotatably installed on the movable connector 120 via the rotating shaft 1301. The end of the swing frame 130 can rotate around... The swing frame 130 swings upward or downward relative to the movable connecting member 120. In this embodiment, the swing frame 130 is generally elongated. Therefore, the swing frame 130 has a driving end 131 and a driven end 132 located on both sides of the rotating shaft 1301. That is, the rotating shaft 1301 is located between the driving end 131 and the driven end 132. When the driving end 131 swings downward around the rotating shaft 1301, the driven end 132 will swing upward around the rotating shaft 1301. Or when the driving end 131 swings upward around the rotating shaft 1301, the driven end 132 will swing downward around the rotating shaft 1301. One end of the elastic drive component 140 is connected to or abuts against the base component, and the other end of the elastic drive component 140 is connected to or abuts against the drive end 131. The elastic drive component 140 can generate an elastic force acting on the drive end 131. The elastic force adjustment component is disposed between the base component and the movable connector 120. All scrapers 200 are disposed on the driven end 132. The elastic force adjustment component can drive the movable connector 120 to move the swing frame 130 closer to or away from the base component, thereby adjusting the magnitude of the elastic force applied by the elastic drive component 140 to the drive end 131.

[0030] The cleaning device of this embodiment has a movable connecting member 120 that can move up and down in the vertical direction to approach or move away from the base assembly, a swing frame 130 rotatably mounted on the movable connecting member 120, one end of the elastic drive component 140 connected to or abutting the base assembly, the other end of the elastic drive component 140 connected to or abutting the drive end 131 of the swing frame 130, and a scraper 200 mounted on the driven end 132 of the swing frame 130. The elasticity adjustment component is disposed between the base assembly and the movable connecting member 120. By adopting the above structure, when the scraper 200 is excessively worn due to prolonged contact with the conveyor belt, the user can drive the movable connector 120 through the elastic adjustment component to move the swing frame 130 closer to the base assembly. The swing frame 130 and the base assembly work together to compress and adjust the elastic drive component 140, thereby increasing the elastic force applied by the elastic drive component 140 to the drive end 131. At this time, the elastic drive component 140 can still apply sufficient elastic force to the drive end 131 of the swing frame 130, so that the swing frame 130 can swing around the rotating shaft 1301 and keep the scraper 200 in close contact with the conveyor belt. Therefore, the service life of the scraper 200 can be extended, the frequency of scraper 200 replacement can be reduced, the maintenance cost of the enterprise can be reduced, and the downtime for replacing the scraper 200 can be reduced, thus improving the production efficiency of the enterprise.

[0031] Reference Figure 1 , Figure 2 and Figure 3To simplify the structure of the cleaning device for conveyor belt transmission equipment according to the present invention, in some embodiments of the present invention, the base assembly includes a first base 110, which can be fixedly installed on the main body 400 of the transmission equipment through other fixed connection structures. A movable connector 120 is movably installed on the first base 110. An elastic adjustment assembly is disposed between the first base 110 and the movable connector 120. One end of the elastic drive assembly 140 is connected to or abuts against the first base 110, and the other end of the elastic drive assembly 140 is connected to or abuts against the drive end 131. The elastic adjustment assembly can drive the movable connector 120 to move upward or downward relative to the first base 110. By adopting the above structure, when the elastic force applied to the drive end 131 by the elastic drive component 140 is insufficient, causing the scraper 200 to fail to adhere tightly to the conveyor belt of the conveyor belt transmission device, the user can drive the movable connector 120 to move upward relative to the first base 110 through the elastic adjustment component. The movable connector 120 drives the swing frame 130 and the scraper 200 to rise synchronously. The first base 110 and the swing frame 130 cooperate to compress and adjust the elastic drive component 140, thereby increasing the elastic force applied to the drive end 131 by the elastic drive component 140. As a result, the swing frame 130 can swing around the rotation axis 1301, keeping the scraper 200 in close contact with the conveyor belt. When the adjustment component is adjusted... When the elastic force applied to the drive end 131 by the elastic drive assembly 140 is too large, causing the scraper 200 to excessively compress the conveyor belt and affect its movement, the user can drive the movable connector 120 to move downward relative to the first base 110 through the elastic adjustment assembly. The movable connector 120 drives the swing frame 130 and the scraper 200 to rise downward simultaneously. The first base 110 and the swing frame 130 reduce the compression of the compression adjustment elastic drive assembly 140, thereby reducing the elastic force applied to the drive end 131 by the adjustment elastic drive assembly 140. This reduces the squeezing force of the scraper 200 on the conveyor belt, preventing the scraper 200 from excessively compressing the conveyor belt and affecting its normal movement.

[0032] To facilitate the installation of the elastic drive assembly 140, in some embodiments of the present invention, the base assembly further includes a second base 111. The second base 111 is connected to the first base 110, or the second base 111 and the first base 110 are separate from each other. Specifically, the second base 111 and the first base 110 can be connected to each other to form a whole, or the second base 111 and the first base 110 are two independent components, and the second base 111 and the first base 110 are separate from each other. One end of the elastic drive assembly 140 is connected to or abuts against the second base 111, and the other end of the elastic drive assembly 140 is connected to or abuts against the drive end 131. By adopting the above structure, when the cleaning device of this embodiment is used to clean the conveyor belt transmission equipment, the first base 110 and the second base 111 can be fixed to different positions of the main body 400 of the transmission equipment by locking bolts, which facilitates the installation of the first base 110 and the second base 111. At the same time, the elastic drive component 140 can be connected or abutted to the second base 111, avoiding the elastic drive component 140 being unable to connect or abut to the first base 110 due to interference from the main body 400 of the transmission equipment, making the installation of the elastic drive component 140 simpler and more convenient.

[0033] To make the structure of the elastic drive assembly 140 more compact, refer to Figure 1 and 2 In some embodiments of the present invention, the elastic drive assembly 140 includes a first screw 141, a first nut 142, and an elastic element 143. The first nut 142 is threadedly connected to the first screw 141. A second base 111 and a drive end 131 are movably sleeved on the outer periphery of the first screw 141, and the second base 111 and the drive end 131 are located between the first screw head of the first screw 141 and the first nut 142. The elastic element 143 is sleeved on the outer periphery of the first screw 141, with one end of the elastic element 143 abutting or connecting to the second base 111, and the other end of the elastic element 143 abutting or connecting to the drive end 131. In this embodiment, the elastic element 143 is a compression spring or a silicone sleeve or rubber sleeve capable of elastic deformation. By adopting the above structure, the structure of the elastic drive assembly 140 is simplified, and it is convenient for both ends of the elastic drive assembly 140 to be connected or abutted to the second base 111 and the drive end 131 in a one-to-one correspondence.

[0034] To facilitate real-time monitoring by users of whether the scraper 200 is pressing tightly against the conveyor belt, refer to... Figure 2 and Figure 3A cleaning device for a conveyor belt conveying equipment according to certain embodiments of the present invention further includes a pressure sensor 300. The pressure sensor 300 is disposed on the elastic drive assembly 140 or the drive end 131. The pressure sensor 300 is used to detect the magnitude of the elastic force applied by the elastic drive assembly 140 to the drive end 131. The pressure sensor is electrically connected to a control circuit. By adopting the above structure, when the cleaning device of this embodiment is used to clean the conveyor belt of the conveyor belt conveying equipment, the scraper 200 is in close contact with the surface of the conveyor belt. At this time, the pressure sensor 300 detects the elastic force applied by the elastic drive assembly 140 to the drive end 131 and feeds back the result to the control circuit. The control circuit can know the change of the elastic force applied by the elastic drive assembly 140 to the drive end 131 in real time. If the elastic force applied by the elastic drive assembly 140 to the drive end 131 fed back by the pressure sensor 300 is much smaller than the set value, the control circuit can determine that the scraper 200 is overloaded. Wear and tear cause the scraper 200 to fail to adhere effectively to the surface of the conveyor belt, resulting in an unsatisfactory cleaning effect on the conveyor belt. If the elastic force applied to the drive end 131 by the elastic drive component 140, as indicated by the pressure sensor 300, is much greater than the set value, the control circuit can determine that a foreign object is stuck between the scraper 200 and the conveyor belt. This causes the swing frame 130 to swing around the rotating shaft 1301, causing the drive end 131 of the swing frame 130 to swing and squeeze the elastic drive component 140. At this time, the control circuit can remind the worker to check and clean the foreign object between the scraper 200 and the conveyor belt.

[0035] Reference Figure 1 and Figure 2To simplify the structure of the elastic adjustment assembly, in some embodiments of the present invention, the elastic adjustment assembly includes a second screw 151 and a second nut 152. The second nut 152 is threadedly connected to the second screw 151. A movable connector 120 and a first base 110 are movably sleeved on the outer periphery of the second screw 151, and the movable connector 120 and the first base 110 are located between the second screw head 1510 and the second nut 152 of the second screw 151. In this embodiment, the second screw head abuts against the movable connector 120, and the second nut 152 abuts against the first base 110. When the elastic adjustment assembly needs to drive the movable connector 120 to move the swing frame 130 and the scraper 200 upward relative to the first base 110, the user only needs to turn the second nut 152 and move it along the second screw 151 closer to the second screw head 1510. At this time, the second screw head 1510 can drive the movable connector 120 to move the swing frame 130 and the scraper. The scraper 200 moves upward relative to the first base 110 and rises. When the elastic adjustment component needs to drive the movable connector 120 to move the swing frame 130 and scraper 200 downward relative to the first base 110 and descend, the user only needs to turn the second nut 152 in the opposite direction and make the second nut 152 move away from the second screw head 1510 along the second screw 151. At this time, the second screw 151 can drive the movable connector 120 to move the swing frame 130 and scraper 200 downward relative to the first base 110 and descend. The operation is simple and convenient.

[0036] It should be noted that, in addition to the structure described above, the elastic adjustment component can also employ other structures. For example, the elastic adjustment component may include a second screw 151, which movably passes through the movable connector 120 and is threadedly connected to the first base 110; or the second screw 151 movably passes through the first base 110 and is threadedly connected to the movable connector 120. By adopting the above structure, when the user rotates the second screw 151 in the forward or reverse direction, the second screw 151 can drive the movable connector 120 to move the swing frame 130 and the scraper 200 relative to the first base 110, causing them to move upward or downward, resulting in a simple structure and quick operation.

[0037] To facilitate the installation of the movable connector 120 on the first base 110, in some embodiments of the present invention, a set of movable connection structures is provided between the movable connector 120 and the first base 110. Each set of movable connection structures includes a strip groove 161 and a connecting bolt 162. The connecting bolt 162 can be movably inserted into the strip groove 161 and can move back and forth along the length direction of the strip groove 161. Specifically, the strip groove 161 is formed in the movable connector 120 in the vertical direction. During installation, the connecting bolt 162 is movably inserted into the strip groove 161 and connected to the first base 110. The first base 110 and the movable connector 120 are movably connected by the connecting bolt 162. Alternatively, a strip groove 161 can be formed along the vertical direction in the first base 110. During installation, a connecting bolt 162 is movably inserted through the strip groove 161, and then connected to the movable connecting member 120. In this case, the first base 110 and the movable connecting member 120 are movably connected by the connecting bolt 162. By adopting the above structure, the connection between the movable connecting member 120 and the first base 110 is achieved, and the movable connecting member 120 and the first base 110 can move relative to each other along the vertical direction, moving closer or further apart. The structure is simple and easy to assemble.

[0038] To ensure a secure connection between the movable connector 120 and the first base 110, in some embodiments of the present invention, two sets of movable connecting structures are provided between the movable connector 120 and the first base 110. These two sets of movable connecting structures are arranged parallel to each other and spaced apart along the horizontal direction between the movable connector 120 and the first base 110. In this embodiment, two strip-shaped grooves 161 of the two sets of movable connecting structures are spaced apart along the vertical direction in the movable connector 120. Connecting bolts 162 are movably installed in each of the two strip-shaped grooves 161, and both connecting bolts 162 are connected to the first base 110. By adopting the above structure, the connection between the first base 110 and the movable connector 120 is more secure and less prone to loosening or falling off.

[0039] Reference Figure 1 and Figure 3To enable the cleaning device of the present invention to better clean the conveyor belt of the conveyor belt transmission equipment, in some embodiments of the present invention, the number of scrapers 200 is two, and the two scrapers 200 are arranged parallel to each other and spaced apart at the driven end 132. By adopting the above structure, when the cleaning device of this embodiment cleans the conveyor belt, the two scrapers 200 can simultaneously press and adhere to the surface of the conveyor belt. Therefore, the two scrapers 200 work together to clean the conveyor belt, resulting in a better cleaning effect. In this embodiment, the ends of both scrapers 200 that contact the conveyor belt are provided with chamfered sections. On the one hand, this reduces the contact area between the scraper 200 and the conveyor belt, generating a greater unit pressure under the same clamping force, thus improving the cleaning effect. On the other hand, it reduces the resistance of the scraper 200 to the conveyor belt, reducing energy consumption and vibration.

[0040] It should be noted that in the above embodiment, the number of scrapers 200 is two. However, in some other embodiments of the present invention, the number of scrapers 200 can be set to three, four or more, depending on actual needs, and is not limited to the two mentioned above.

[0041] Reference Figure 1 In some embodiments of the present invention, there are two sets of elastic drive adjustment mechanisms 100. The two sets of elastic drive adjustment mechanisms 100 are arranged parallel to each other and spaced apart along the length direction of the scraper 200. One end of all scrapers 200 is connected to the driven end 132 of one set of elastic drive adjustment mechanisms 100, and the other end of all scrapers 200 is connected to the driven end 132 of the other set of elastic drive adjustment mechanisms 100. By adopting the above structure, the cleaning device of this embodiment uses two sets of elastic drive adjustment mechanisms 100 to connect one-to-one to the two ends of the support scraper 200. This allows the cleaning device of this embodiment to be applicable to scrapers 200 with longer support lengths, enabling the scraper 200 to be used to clean conveyor belts with wider surfaces, thus increasing the application range of the cleaning device of this embodiment. In addition, during actual use, if one end of the scraper 200 is worn excessively while the other end is worn less, the user can adjust the elastic drive adjustment mechanism 100 on the more worn end of the scraper 200. The elastic drive adjustment mechanism 100 drives the more worn end of the scraper 200 to move upward and rise, pressing it tightly against the conveyor belt. This ensures that both ends of the scraper 200 are pressed tightly against the conveyor belt with essentially the same pressure, extending the service life of the scraper 200 while ensuring the cleaning effect of the cleaning device, thus meeting the needs of enterprises.

[0042] Reference Figure 1 , Figure 2 and Figure 3The cleaning device of certain embodiments of the present invention is used to clean the conveyor belt of a conveyor belt transmission device as follows: First, the first base 110 and the second base 111 are respectively locked to the main body 400 of the transmission device using different locking bolts. At this time, the two scrapers 200 at the driven end of the swing frame 130 are pressed and pressed against the conveyor belt 410. One scraper 200 is pressed against the tangent point between the conveyor belt 410 and the conveyor cylinder 420, while the other scraper 200 is pressed against the side surface of the conveyor belt 410 away from the conveyor cylinder 420. Then, the user turns the second nut 152. The second nut 152 and the second screw 151 cooperate and drive the driving movable connector 120 to move. The swing frame 130 and scraper 200 move upward relative to the first base 110, so that the elastic drive assembly 140 generates sufficient elastic force to act on the drive end 131 of the swing frame 130, thereby causing the two scrapers 200 to press tightly against the conveyor belt 410. The pressure sensor 300 detects the elastic force applied by the elastic drive assembly 140 to the drive end 131 and feeds it back to the control circuit. The control circuit sets the elastic force at this time as the reference pressure value Fs. Then the conveyor belt 410 of the conveyor belt transmission device can normally transport and convey materials, and the cleaning device of this embodiment can also normally clean the conveyor belt 410. After the cleaning device has been working for a period of time, if the pressure... Force sensor 300 detects that the elastic force Fc applied by elastic drive assembly 140 to drive end 131 is sufficient, and Fc < 80% Fs. The control circuit can then determine that wear on scraper 200 or loosening of some parts has caused the cleaning device to fail to clean the conveyor belt 410. In this case, the control circuit can alert the worker to the malfunction via a buzzer, warning light, or display. The worker can then readjust the elastic force applied by elastic drive assembly 140 to drive end 131 of swing frame 130 by tightening the second nut 152, thereby causing the two scraper 200s at the driven end of swing frame 130 to press and adhere tightly to the conveyor belt 410. After the cleaning device has worked for a period of time... After a period of time, if the pressure sensor 300 detects that the elastic force Fc applied by the elastic drive component 140 to the drive end 131 is greater than or equal to 1.1Fs, the control circuit can determine that material has been lodged between the scraper 200 and the conveyor belt 410, causing the elastic drive component 140 to be further compressed. At this time, the cleaning device fails to clean the conveyor belt 410. The control circuit can remind the worker of the cleaning device malfunction through a buzzer, warning light, or display. The worker can then clean the material between the scraper 200 and the conveyor belt 410, thereby enabling the cleaning device of this embodiment to clean the conveyor belt 410 of the conveyor belt transmission equipment stably and reliably, resulting in a better cleaning effect.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
