Description

Technical Field

[0001] The invention relates to the field of conveyor belt transmission equipment, in particular to a cleaning device applied to conveyor belt transmission equipment. Background Art

[0002] With the development of society and the continuous progress of science and technology, the equipment used to transport workpieces or materials has become more and more diverse, among which belt conveyors are the material transmission equipment often used by enterprises. Belt conveyors are widely used in the transportation of various bulk materials. Usually, for belt conveyors with a lifting angle of less than 18°, smooth belts are mostly used. In order to keep the belt surface clean, most companies will install various types of scraper cleaners on the belt head of the belt conveyor. The scraper cleaner cleans the surface of the belt through the scraper cleaner.

[0003] However, in the field of solid waste bulk material transportation, due to the complexity of solid waste components, typical materials such as mixed domestic waste include wet and sticky organic waste, such as leftovers, etc., as well as a large amount of plastic film and garbage bags, as well as hard materials such as sand, stone, and metal, and fibrous materials such as clothes, hair, and wool. The complexity of the conveyed materials poses a great challenge to the cleaning of the belt surface. Conventional scraper cleaners used for belt cleaning have the following problems: When the scraper cleaner cleans the belt surface, the scraper skin of the scraper cleaner can be pressed tightly against the surface of the belt, and the belt conveyor will drive the belt to rotate back and forth continuously during the working process, so the belt will continuously rub the scraper and cause the scraper to be worn, and a gap will be generated between the scraper and the belt, resulting in the scraper cleaner being unable to clean the belt surface.

[0004] To this end, some scraper cleaners that use elastic force to drive the scraper to be close to the belt have appeared on the market. These scraper cleaners generally adopt the following structure, including a fixed base, a swing rod, a compression spring and a scraper. The fixed base can be fixedly installed on the frame of the belt conveyor, and the middle part of the swing rod is rotatably installed on the middle and lower part of the fixed base through a rotating shaft. The swing rod 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 rod. The scraper is installed at the front end of the swing rod. 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 rod is close to the surface of the belt, and the compression spring is in a compressed state, so that the compression spring can generate elastic force and act on the rear end of the swing rod. When the scraper is worn by the subsequent belt, the compression spring can drive the swing rod to rotate around the rotating shaft and keep the scraper in a state of pressing the belt surface, thereby solving the technical problem that the scraper cannot clean the belt surface due to the gap between the scraper and the belt in the existing scraper cleaner.

[0005] Although the scraper cleaner that uses elastic force to drive the scraper to stick to the belt can solve the problem that the scraper cannot stick to the belt due to wear, since the compressed length of the compression spring is limited, when the scraper is worn too thick, the compression spring cannot drive the scraper to stick to the surface of the belt. The company can only stop the machine to replace the new scraper and readjust the compressibility of the compression spring. This is not only troublesome to operate, but also time-consuming and labor-intensive, which greatly reduces the company's production efficiency. Summary of the invention

[0006] The present invention aims to solve at least 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 device, which can adjust the elastic force applied by the elastic drive component to the swing rod, thereby allowing the scraper to be close to the surface of the conveyor belt.

[0028] Figures 1 to 3 It is a schematic diagram of some embodiments of a cleaning device applied to a conveyor belt transmission equipment of the present invention.

[0029] Reference Figures 1 to 3 , and mainly refer to Figure 2 and Figure 3, according to certain embodiments of the present invention, a cleaning device applied to a conveyor belt transmission device, for ease of explanation, is sometimes referred to as a "cleaning device" hereinafter. A cleaning device applied to a conveyor belt transmission device includes a set of elastic-driven adjustment mechanisms 100 and one or more scrapers 200. In this embodiment, the elastic-driven adjustment mechanism 100 includes a base assembly, a movable connection 120, a swing frame 130, an elastic drive assembly 140 and an elastic adjustment assembly. The base assembly can be fixedly mounted on a transmission device body 400 or a base frame or a connecting frame of the conveyor belt transmission device, etc. The movable connection 120 is movably mounted on the base assembly. The movable connection 120 can move in the up and down directions to approach or move away from the base assembly. The lower part of the base assembly is provided with a rotating shaft 1301 arranged in the horizontal direction. The middle part of the swing frame 130 is rotatably mounted on the movable connection 120 through the rotating shaft 1301. The end of the swing frame 130 can rotate around As the rotating shaft 1301 swings upward and rises or swings downward and falls relative to the movable connecting member 120, in the present embodiment, the swing frame 130 is in the shape of an elongated strip as a whole, so the swing frame 130 has a driving end 131 and a driven end 132 which are correspondingly 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. At this time, when the driving end 131 swings downward around the rotating shaft 1301, the driven end 132 will swing upward and rise 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 and fall around the rotating shaft 1301. One end of the elastic driving component 140 is connected to or abuts the base component, and the other end of the elastic driving component 140 is connected to or abuts the driving end 131. The elastic driving component 140 can generate an elastic force acting on the driving end 131. The elastic force adjustment component is arranged between the base component and the movable connecting member 120, and all the scrapers 200 are arranged at the driven end 132; the elastic force adjustment component can drive the movable connecting member 120 to drive the swing frame 130 to move closer to or away from the base component, thereby adjusting the elastic force applied by the elastic driving component 140 to the driving end 131.

[0030] The cleaning device of this embodiment is formed by movably installing a movable connecting piece 120 on the base assembly that can move closer or farther along the up and down directions. The swing frame 130 is rotatably installed on the movable connecting piece 120. One end of the elastic driving component 140 is connected or abutted with the base assembly, and the other end of the elastic driving component 140 is connected or abutted with the driving end 131 of the swing frame 130. The scraper 200 is installed on the driven end 132 of the swing frame 130, and the elastic force adjustment component is arranged between the base assembly and the movable connecting piece 120. By adopting the above-mentioned structure, when the scraper 200 is in close contact with the conveyor belt for a long time and is excessively worn, the user can drive the movable connecting part 120 through the elastic force adjustment component to drive the swing frame 130 to move closer to the base component. The swing frame 130 and the base component cooperate to compress and adjust the elastic driving component 140, thereby increasing the elastic force applied by the elastic driving component 140 to the driving end 131. At this time, the elastic driving component 140 can still apply sufficient elastic force to the driving 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, and the frequency of replacing the scraper 200 by the enterprise can be reduced, which not only reduces the maintenance cost of the enterprise, but also reduces the time of downtime for replacing the scraper 200 by the enterprise, thereby improving the production efficiency of the enterprise.

[0031] Reference Figure 1 , Figure 2 and Figure 3In order to make the structure of a cleaning device applied to a conveyor belt transmission equipment of the present invention simpler, in some embodiments of the present invention, the base assembly includes a first base 110, and the first base 110 can be fixedly installed on the transmission equipment body 400 through other fixed connection structures. The movable connecting member 120 is movably installed on the first base 110, and the elastic adjustment assembly is arranged between the first base 110 and the movable connecting member 120. One end of the elastic driving assembly 140 is connected to or abuts the first base 110, and the other end of the elastic driving assembly 140 is connected to or abuts the driving end 131. The elastic adjustment assembly can drive the movable connecting member 120 to move upward or downward relative to the first base 110. By adopting the above structure, when the elastic force applied by the elastic driving component 140 to the driving end 131 is insufficient and the scraper 200 cannot be close to the conveyor belt of the conveyor belt transmission equipment, the user can drive the movable connecting member 120 to move upward and rise relative to the first base 110 through the elastic force adjustment component, and the movable connecting member 120 drives the swing frame 130 and the scraper 200 to rise upward synchronously, and the first base 110 and the swing frame 130 cooperate to compress and adjust the elastic driving component 140, so that the elastic force applied by the elastic driving component 140 to the driving end 131 is increased, and then the swing frame 130 can swing around the rotating shaft 1301 and keep the scraper 200 close to the conveyor belt; when the elastic force adjustment component 140 is adjusted, the elastic force applied by the elastic driving component 140 to the driving end 131 is increased, and then the swing frame 130 can swing around the rotating shaft 1301 and keep the scraper 200 close to the conveyor belt. When the elastic force applied by the elastic drive component 140 to the driving end 131 is too large, so that the scraper 200 over-extrudes the conveyor belt and affects the movement of the conveyor belt, the user can drive the movable connection 120 to move downward relative to the first base 110 through the elastic force adjustment component, and the movable connection 120 drives the swing frame 130 and the scraper 200 to rise downward synchronously, and the first base 110 and the swing frame 130 reduce the squeezing of the compression adjustment elastic drive component 140, so that the elastic force applied by the adjustment elastic drive component 140 to the driving end 131 is reduced, thereby reducing the squeezing force of the scraper 200 on the conveyor belt, and avoiding the scraper 200 from over-extruding the conveyor belt and affecting the normal movement and operation of the conveyor belt.

[0032] In order 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, and the second base 111 is connected to the first base 110, or the second base 111 and the first base 110 are separated 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 separated from each other. One end of the elastic drive assembly 140 is connected to or abutted with the second base 111, and the other end of the elastic drive assembly 140 is connected to or abutted with the driving end 131. By adopting the above-mentioned 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 transmission equipment body 400 by locking bolts alone, which is convenient for the installation of the first base 110 and the second base 111. At the same time, the elastic drive component 140 can be correspondingly connected or abutted with the second base 111 to avoid the elastic drive component 140 being interfered by the transmission equipment body 400 and unable to connect or abut with the first base 110, making the installation of the elastic drive component 140 simpler and more convenient.

[0033] In order 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 member 143, the first nut 142 is threadedly connected to the first screw 141, the second base 111 and the driving end 131 are movably sleeved on the outer periphery of the first screw 141, and the second base 111 and the driving end 131 are located between the first screw head of the first screw 141 and the first nut 142, the elastic member 143 is sleeved on the outer periphery of the first screw 141, one end of the elastic member 143 abuts or connects with the second base 111, and the other end of the elastic member 143 abuts or connects with the driving end 131. In this embodiment, the elastic member 143 is a compression spring or a silicone sleeve or a rubber sleeve that can undergo elastic deformation. By adopting the above structure, the structure of the elastic drive assembly 140 is simplified, and at the same time, it is convenient for the two ends of the elastic drive assembly 140 to be connected or abutted with the second base 111 and the driving end 131 in a one-to-one correspondence.

[0034] In order to facilitate the user to monitor in real time whether the scraper 200 is pressed against the conveyor belt, refer to Figure 2 and Figure 3In some embodiments of the present invention, a cleaning device applied to a conveyor belt transmission equipment further includes a pressure sensor 300. The pressure sensor 300 is disposed on the elastic drive component 140 or the drive end 131. The pressure sensor 300 is used to detect the size of the elastic force applied by the elastic drive component 140 to the drive end 131. The pressure sensor 300 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 transmission 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 component 140 to the drive end 131 and feeds back the result to the control circuit. The control circuit can obtain the change of the elastic force applied by the elastic drive component 140 to the drive end 131 in real time. If the elastic force applied by the elastic drive component 140 to the drive end 131 fed back by the pressure sensor 300 is much less than the set value, the control circuit can determine that the scraper 200 is over- Due to wear, the scraper 200 cannot effectively adhere to the surface of the conveyor belt, and the cleaning device has an unsatisfactory cleaning effect on the conveyor belt. If the elastic force applied to the driving end 131 by the elastic driving component 140 fed back by the pressure sensor 300 is much greater than the set value, the control circuit can determine that a foreign object is inserted between the scraper 200 and the conveyor belt, and then drive the swing frame 130 to swing around the rotating shaft 1301, so that the driving end 131 of the swing frame 130 swings and squeezes the elastic driving component 140. At this time, the control circuit can remind the worker to check and clean the foreign objects between the scraper 200 and the conveyor belt.

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

[0036] It should be noted that, in addition to the above-mentioned structure, the elastic force adjustment component may also adopt other structures, such as the elastic force adjustment component includes a second screw rod 151, the second screw rod 151 movably passes through the movable connecting member 120 and is threadedly connected to the first base 110; or the second screw rod 151 movably passes through the first base 110 and is threadedly connected to the movable connecting member 120. By adopting the above-mentioned structure, when the user screws the second screw rod 151 to rotate forward or reverse, the second screw rod 151 can drive the movable connecting member 120 to drive the swing frame 130 and the scraper 200 to move upward and rise or move downward and fall relative to the first base 110, which has a simple structure and quick operation.

[0037] In order to facilitate the installation of the movable connecting member 120 on the first base 110, in some embodiments of the present invention, a group of movable connection structures are provided between the movable connecting member 120 and the first base 110, each group of movable connection structures includes a strip groove 161 and a connecting bolt 162, the connecting bolt 162 can be movably installed in the strip groove 161, and the connecting bolt 162 can move back and forth along the length direction of the strip groove 161. Specifically, the strip groove 161 is opened in the movable connecting member 120 along the up-down direction, and during installation, the connecting bolt 162 is movably installed in the strip groove 161, and the connecting bolt 162 is connected to the first base 110, and the first base 110 and the movable connecting member 120 are movably connected through the connecting bolt 162. Alternatively, the strip groove 161 is opened in the first base 110 along the up-down direction. During installation, the connecting bolt 162 is movably installed in the strip groove 161, and the connecting bolt 162 is then connected to the movable connecting member 120. At this time, the first base 110 and the movable connecting member 120 are movably connected through the connecting bolt 162. By adopting the above structure, the connection between the movable connecting member 120 and the first base 110 is realized, and the movable connecting member 120 and the first base 110 can move relatively close to or away from each other along the up-down direction, and the structure is simple and easy to assemble.

[0038] In order to make the connection between the movable connecting member 120 and the first base 110 firm, in some embodiments of the present invention, two sets of movable connecting structures are provided between the movable connecting member 120 and the first base 110, and the two sets of movable connecting structures are arranged parallel to each other and spaced apart along the horizontal direction between the movable connecting member 120 and the first base 110. In this embodiment, two strip grooves 161 of the two sets of movable connecting structures are spaced apart along the vertical direction in the movable connecting member 120, and connecting bolts 162 are movably installed in the two strip grooves 161, and the two 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 connecting member 120 is firmer and not easy to loosen and fall off.

By adopting the above structure, when the cleaning device of this embodiment cleans the conveyor belt, it can simultaneously squeeze the surface of the conveyor belt tightly by the two scrapers 200, so the two scrapers 200 work together to clean the conveyor belt, so that the cleaning device of this embodiment has a better effect on cleaning the conveyor belt. In this embodiment, the ends of the two scrapers 200 that contact the conveyor belt are both provided with cross-sectional chamfers, which, on the one hand, reduce the contact area between the scraper 200 and the conveyor belt, and under the same pressing force, can generate a larger unit pressure to improve the cleaning effect, and on the other hand, reduce the resistance of the scraper 200 to the conveyor belt, reduce energy consumption and vibration.

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

[0041] Reference Figure 1 In certain embodiments of the present invention, there are two groups of elastic-driven adjustment mechanisms 100, and the two groups of elastic-driven adjustment mechanisms 100 are arranged parallel to and spaced apart from each other along the length direction of the scraper 200. One end of all the scrapers 200 is connected to the driven end 132 of one group of the elastic-driven adjustment mechanisms 100, and the other end of all the scrapers 200 is connected to the driven end 132 of the other group of the elastic-driven adjustment mechanisms 100. By adopting the above-mentioned structure, the cleaning device of this embodiment adopts two sets of elastic-driven adjustment mechanisms 100 to connect the two ends of the supporting scraper 200 in a one-to-one correspondence, so that the cleaning device of this embodiment can be suitable for supporting scrapers 200 with longer lengths, so that the scraper 200 can be used to clean conveyor belts with wider surface widths, thereby increasing the use range of the cleaning device of this embodiment. In addition, in actual use, if one end of the scraper 200 is worn too much and the other end of the scraper 200 is less worn, the user can adjust the elastic-driven adjustment mechanism 100 at the end of the scraper 200 that is more worn, and drive the end of the scraper 200 that is more worn to move upward and rise and close to the conveyor belt through the elastic-driven adjustment mechanism 100, so that the two ends of the scraper 200 are basically kept consistent and squeezed close to the conveyor belt, which not only extends the service life of the scraper 200, but also ensures the cleaning effect of the cleaning device to meet the needs of the enterprise.

[0042] Reference Figure 1 , Figure 2 and Figure 3The cleaning device of some embodiments of the present invention is used to clean the conveyor belt of the conveyor belt transmission equipment as follows: first, different locking bolts are used to respectively lock the first base 110 and the second base 111 to the transmission equipment body 400, at which time the two scrapers 200 at the driven end of the swing frame 130 squeeze and cling to the conveyor belt 410, one of the scrapers 200 is pressed against the tangent point between the conveyor belt 410 and the conveying cylinder 420, and the other scraper 200 is pressed against the side surface of the conveyor belt 410 away from the conveying cylinder 420, and then the user screws the second nut 152, and the second nut 152 cooperates with the second screw rod 151 and drives the active connecting member 120 to drive The swing frame 130 and the scraper 200 move upward and rise relative to the first base 110, so that the elastic drive component 140 generates sufficient elastic force to act on the driving end 131 of the swing frame 130, thereby making the two scrapers 200 close to and squeeze the conveyor belt 410. The pressure sensor 300 detects the elastic force applied by the elastic drive component 140 to the driving 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, and then the conveyor belt 410 of the conveyor belt transmission equipment can normally transport and transport 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 The force sensor 300 detects that the elastic force applied by the elastic drive component 140 to the driving end 131 is Fc, and Fc < 80% Fs. The control circuit can determine that the scraper 200 of the cleaning device is worn or some parts are loose, resulting in the cleaning failure of the cleaning device to the conveyor belt 410. In this case, the control circuit can remind the worker of the failure of the cleaning device through a buzzer, a warning light, or a display. The worker readjusts the elastic force applied by the elastic drive component 140 to the driving end 131 of the swing frame 130 by screwing the second nut 152, thereby causing the two scrapers 200 at the driven end of the swing frame 130 to squeeze and cling to the conveyor belt 410. When the cleaning device works for a period of time, the second nut 152 is turned to adjust the elastic force applied by the elastic drive component 140 to the driving end 131 of the swing frame 130, thereby causing the two scrapers 200 at the driven end of the swing frame 130 to squeeze and cling to the conveyor belt 410. After a period of time, if the pressure sensor 300 detects that the elastic force applied by the elastic drive component 140 to the driving end 131 is Fc, and Fc>1.1Fs, the control circuit can determine that material is stuffed 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 workers of the failure of the cleaning device through a buzzer, warning light or display, and the workers can clean the material between the scraper 200 and the conveyor belt 410, so that the cleaning device of this embodiment can stably and reliably clean the conveyor belt 410 of the conveyor belt transmission equipment, and the cleaning effect is better.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
