Description

Technical Field

[0001] This invention relates to the field of belt conveyor cleaning technology, specifically to a belt conveyor cleaning device and its usage method. Background Technology

[0002] Belt conveyors, as continuous transport machinery, have become indispensable and economical logistics conveying equipment in assembly lines across various industries. However, due to material spillage and adhesion to the belt during transport, workers need to regularly clean up the spilled material. Traditional fixed cleaning devices mostly use wear-resistant metal scrapers that are in close contact with the belt to scrape off the residual material. However, the efficiency of this type of cleaning device is limited, and the scrapers inevitably wear down with prolonged use. Patent documents have now addressed this issue.

[0003] For example, Chinese patent CN107324010A discloses a cleaning device for a conveyor belt. This cleaning device includes: a support frame disposed below the return area of ​​the conveyor belt; a brush roller rotatably mounted on the support frame via a roller shaft, capable of contacting the return area of ​​the conveyor belt to clean residual material adhering to it; and a transmission mechanism connected to both the conveyor belt's rollers or belt and the brush roller, enabling the conveyor belt to drive the brush roller to rotate. This cleaning device for conveyor belts effectively cleans residual material adhering to the conveyor belt, avoiding waste of manpower and resources, and also reduces wear on the conveyor belt during the cleaning process, extending the service life of the conveyor belt.

[0004] Although the aforementioned patent uses a softer brush to clean the tape, its practicality in actual use is low, for example: The belt conveyors on the market are not only flat, but also have belts with grooves to increase friction. When using this type of belt, particulate impurities are easy to get stuck in the grooves and cannot be swept out by a soft brush. The device has a relatively simple structure and can only remove obvious particulate stains on the surface with a soft brush. However, it is not very efficient at removing attached dust and tightly adhered stains, resulting in low applicability. Therefore, a belt conveyor cleaning device that can more comprehensively clean the belt and has high applicability has been designed to solve these defects. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a belt conveyor cleaning device and its usage method, which solves the problems of low applicability and poor cleaning effect of existing equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tape conveyor cleaning device, comprising an installation mechanism, wherein the installation mechanism includes a cleaning frame, and a cleaning mechanism for cleaning tape is installed on the inner side of the cleaning frame.

[0007] Preferably, the cleaning mechanism includes a drive motor, which is mounted on the right side of the front of the cleaning frame via a bracket.

[0010] Preferably, the bottom of the front support frame is rotatably connected to a fourth rotating rod via a bearing. The rear end of the fourth rotating rod and the top end of the front vertical rod are both fixedly connected to meshing bevel gears. The second rotating rod, the fourth rotating rod, and the third rotating rod are connected by a third pulley and a third belt drive. The top of the barrier plate is fixedly connected to a liquid collection frame. The right side of the liquid collection frame is fixedly connected to a flushing pipe through an opening, and several flushing pipes are provided.

[0011] Preferably, a through slot is provided on the left side of the rear of the cleaning frame, and a liquid collection tank is fixedly connected to the lower side of the rear of the cleaning frame by a fixing block. A sealed liquid extraction cylinder is fixedly connected to the inner side of the through slot, and the bottom end of the sealed liquid extraction cylinder extends to the inner side of the liquid collection tank. The top of the inner cavity of the sealed liquid extraction cylinder is rotatably connected to an auger rod through a bearing, and the bottom end of the auger rod extends to the inner side of the liquid collection tank. A first rotating rod is rotatably connected to the rear of the liquid collection tank through an opening. The front end of the first rotating rod and the bottom end of the auger rod are rotatably connected by a universal joint. A flexible hose is fixedly connected to the top of the sealed liquid extraction cylinder through an opening, and one end of the flexible hose passes through the liquid collection frame and extends to the inner side of the liquid collection frame. The rear ends of the second rotating rod and the first rotating rod are connected by a first pulley and a first belt drive.

[0012] Preferably, a liquid receiving frame is fixedly connected to the bottom of the inner cavity of the cleaning frame, and overlapping strips are fixedly connected to both sides of the inner cavity of the liquid receiving frame. A filter screen is placed between the tops of the two overlapping strips. A return pipe is fixedly connected to the rear of the liquid receiving frame through an opening, and the rear end of the return pipe passes through the cleaning frame and extends to the upper part of the liquid collection tank.

[0013] Preferably, a sliding sleeve is fixedly connected to the front and rear of both sides of the bottom of the cleaning frame. A support column is slidably installed on the inner side of the sliding sleeve. A load-bearing base plate is fixedly connected between the four support columns. An anti-slip roller is fixedly connected to the bottom of the sliding sleeve. A cylinder is fixedly connected to the top of the load-bearing base plate through an opening, and the top of the cylinder is fixedly connected to the bottom of the cleaning frame.

[0014] This invention also discloses a method for using a belt conveyor cleaning device, specifically including the following steps: S1. Before use, inject cleaning agent into the inside of the collection tank and mix with water. Then, push the cleaning frame to move under the action of the anti-slip rollers. At the same time, start the cylinder to raise the cleaning frame and adjust the height of the side wall plate and the baffle plate. When the conveyor belt is directly below the side wall plate, start the cylinder to drive the cleaning frame to descend as a whole, so that the two side wall plates are at the front and rear of the conveyor belt. At the same time, the baffle plate contacts the left side of the top of the conveyor belt. During the descent of the cleaning frame, the roller brush will contact the top of the conveyor belt and press up with the thrust of the thrust spring to make it stick tightly to the top of the conveyor belt. At this time, the right side of the conveyor belt abuts against the roller brush cylinder. Then proceed to step S2 for the cleaning process. S2. When performing the cleaning process, start the conveyor belt to drive the top conveyor belt, and then start the drive motor to drive the second rotating rod to rotate. When the second rotating rod rotates, it will drive the first rotating rod, the fourth rotating rod, and the third rotating rod to rotate simultaneously through the third pulley, the third belt, the first pulley, and the first belt. The rotation of the third rotating rod will drive the upper top rod to contact the lifting rod, continuously lifting the arc-shaped striking plate. After the upper top rod separates from the lifting rod, the arc-shaped striking plate will strike the conveyor belt downwards through the tension of the tension spring, knocking out the particles stuck in the gaps of the conveyor belt and breaking up the solidified impurities on the surface. Then the conveyor belt continues to move forward. At this time, the rotation of the first rotating rod drives the auger rod to rotate through the universal joint, which draws the cleaning agent inside the collection tank upward. Then, the upward pressure of the auger rod causes the cleaning agent to be injected into the inside of the collection frame through the hose. Then, the cleaning agent flows out through the flushing pipe and sprays onto the top of the tape. Because the two side wall plates and the baffle plate wrap the three sides of the tape and the tape keeps moving to the right, the cleaning agent flows to the right under the action of the tape. When the fourth rotating rod rotates, it drives the vertical rod to rotate the roller brush disc through the meshing of two bevel gears and the transmission of the second pulley and the second belt. This, combined with the action of the cleaning agent, washes the surface of the tape. The cleaning agent flows out from the right side and all sides and falls into the inner side of the receiving frame. When the tape moves to the far right, it undergoes a second, more forceful wash by the roller brush. The filter screen filters out the dirt, causing the cleaning agent to fall to the bottom of the receiving frame and be discharged back into the collection tank through the return pipe. Then, the tape is pulled out again by the auger for further cleaning. S3. After cleaning, drain the cleaning agent from the collection tank and replace it with clean water. Repeat step S2 to rinse the tape until the surface is clean. After rinsing, start the cylinder to push the cleaning frame up and separate it from the tape. Then remove the equipment and take out the filter screen for cleaning.

[0015] Preferably, the hose in step S2 is made of elastic rubber. Beneficial effects

[0016] This invention provides a cleaning device and method for using a conveyor belt. Compared with existing technologies, it has the following advantages: (1) The cleaning device and usage method of the belt conveyor combines the installation mechanism and the cleaning mechanism and drives it with a drive motor. The transmission of the third pulley, the third belt, the first pulley and the first belt can simultaneously complete the processes of beating, rinsing and brushing when cleaning the belt, removing dust and adhering substances from the belt surface, resulting in high cleaning quality and convenient use. It is also suitable for different types of belt conveyors.

[0017] (2) The cleaning device and method of the conveyor belt: an arc-shaped striking plate is rotatably connected to the left side of the barrier plate and a lifting rod is installed on its top. It is used in conjunction with the top rod. The structure can continuously lift the arc-shaped striking plate by contacting the lifting rod when the top rod rotates. Then, the tension of the tension spring is used to make the arc-shaped striking plate beat the conveyor belt, and the particles in the concave groove of the conveyor belt are discharged, thereby improving the cleaning force and detail.

[0018] (3) The cleaning device and usage method of the belt conveyor are as follows: a sealed liquid extraction cylinder is installed by opening a through slot at the rear of the cleaning frame. The sealed liquid extraction cylinder is equipped with an auger rod, which is used in conjunction with a liquid collection frame and a liquid receiving frame. The configuration of these structures can filter and circulate the cleaning agent through the drive motor, and can reduce the installation of water pumps and reduce energy consumption.

[0019] (4) The cleaning device and usage method of the conveyor belt: By setting up interconnected side wall plates and barrier plates on the inside of the cleaning frame, the front, back and left sides of the conveyor belt can be wrapped to prevent the cleaning agent from leaking out in advance and ensure the cleanliness of the inside of the equipment.

[0028] The advantage of Embodiment 2 over Embodiment 1 is that, by rotatably connecting an arc-shaped striking plate 214 to the left side of the barrier plate 205 and installing a lifting rod 216 on its top, it works in conjunction with the top rod 218. This configuration allows the arc-shaped striking plate 214 to be continuously lifted by contacting the lifting rod 216 when the top rod 218 rotates. Then, the tension of the tension spring 215 causes the arc-shaped striking plate 214 to strike the tape, discharging particles from the tape's crevices, thus improving the cleaning force and detail. Furthermore, by opening a through slot 102 at the rear of the cleaning frame 101... The equipment is equipped with a sealed liquid extraction cylinder 104, inside which is installed an auger rod 105. It is used in conjunction with a liquid collection frame 223 and a liquid receiving frame 111. These structures enable the cleaning agent to be filtered and circulated by the drive motor 201, and can reduce the installation of a water pump and reduce energy consumption. By installing interconnected side wall plates 204 and barrier plates 205 on the inner side of the cleaning frame 101, these two structures can wrap the front, back and left sides of the tape, preventing the cleaning agent from leaking out prematurely and ensuring the cleanliness of the inside of the equipment.

[0029] This invention also discloses a method for using a belt conveyor cleaning device, specifically including the following steps: S1. Before use, inject cleaning agent into the inside of the collection tank 103 and mix with water. Then push the cleaning frame 101 to move under the action of the anti-slip roller 118. At the same time, start the cylinder 119 to raise the cleaning frame 101 and adjust the height of the side wall plate 204 and the barrier plate 205. When the conveyor belt is directly below the side wall plate 204, start the cylinder 119 to drive the cleaning frame 101 to descend as a whole, so that the two side wall plates 204 are located at the front and rear of the conveyor belt. At the same time, the barrier plate 205 contacts the left side of the top of the conveyor belt. During the descent of the cleaning frame 101, the roller brush 211 will contact the top of the conveyor belt and will be pressed by the thrust of the thrust spring 209 to make it stick tightly to the top of the conveyor belt. At this time, the right side of the conveyor belt abuts against the roller brush cylinder 203. Then proceed to step S2 for the cleaning process. S2. When performing the cleaning process, start the conveyor belt to drive the top conveyor belt. Then start the drive motor 201 to drive the second rotating rod 202 to rotate. When the second rotating rod 202 rotates, it will drive the first rotating rod 107, the fourth rotating rod 219 and the third rotating rod 217 to rotate through the third pulley 221, the third belt 222 and the first pulley 109 and the first belt 110. The rotation of the third rotating rod 217 will drive the upper top rod 218 to contact the lifting rod 216 and continuously lift the arc-shaped striking plate 214. After the upper top rod 218 is separated from the lifting rod 216, the arc-shaped striking plate 214 will strike the conveyor belt downward through the tension of the tension spring 215, knocking out the particles stuck in the gap of the conveyor belt and breaking up the solidified impurities on the surface. Then the conveyor belt continues to move forward. At this time, the rotation of the first rotating rod 107 drives the auger rod 105 to rotate through the universal joint 108, which draws the cleaning agent inside the collection tank 103 upward. Then, the upward pressure of the auger rod 105 causes the cleaning agent to be injected into the inside of the collection frame 223 through the hose 106. Then, the cleaning agent flows out through the flushing pipe 224 and sprays onto the top of the tape. Because the two side wall plates 204 and the baffle plate 205 wrap the three sides of the tape and the tape moves to the right, the cleaning agent flows to the right under the action of the tape. When the fourth rotating rod 219 rotates, it drives the vertical rod 210 to rotate the roller brush disc 211 through the meshing of two bevel gears 220 and the transmission of the second pulley 212 and the second belt 213. This, combined with the action of the cleaning agent, washes the surface of the tape. The cleaning agent flows out from the right side and all sides and falls into the inner side of the liquid receiving frame 111. When the tape moves to the far right, it undergoes a second strong wash by the roller brush cylinder 203. The filter screen 113 filters the dirt, causing the cleaning agent to fall into the bottom of the liquid receiving frame 111 and be discharged back into the inner side of the collection tank 103 through the return pipe 114. Then, the tape is pulled out again by the auger rod 105 for further cleaning. S3. After cleaning, drain the cleaning agent from the collection tank 103 and replace it with clean water. Repeat step S2 to rinse the tape until the surface is clean. After rinsing, start cylinder 119 to push the cleaning frame 101 up and separate it from the tape. Then remove the equipment and take out the filter screen 113 for cleaning. The hose 106 in step S2 is made of elastic rubber.

9. A method of using a belt conveyor cleaning device, characterized in that: Specifically, the following steps are included: S1. Before use, first inject cleaning agent into the inside of the collection tank (103) and add water to mix well. Then push the cleaning frame (101) to move under the action of the anti-slip roller (118). At the same time, start the cylinder (119) to raise the cleaning frame (101) and adjust the height of the side wall plate (204) and the barrier plate (205). When the conveyor belt is directly below the side wall plate (204), start the cylinder (119) to drive the cleaning frame (101) to descend as a whole, so that the two side wall plates (204) are located at the front and rear of the conveyor belt. At the same time, the barrier plate (205) contacts the left side of the top of the conveyor belt. During the descent of the cleaning frame (101), the roller brush plate (211) will contact the top of the conveyor belt and will be pressed by the thrust of the thrust spring (209) to make it stick tightly to the top of the conveyor belt. At this time, the right side of the conveyor belt is against the roller brush cylinder (203). Then proceed to step S2 for the cleaning process. S2. When performing the cleaning process, start the conveyor belt to drive the top conveyor belt. Then start the drive motor (201) to drive the second rotating rod (202) to rotate. When the second rotating rod (202) rotates, it will drive the first rotating rod (107), the fourth rotating rod (219) and the third rotating rod (217) to rotate through the third pulley (221), the third belt (222), the first pulley (109) and the first belt (110). The rotation of the third rotating rod (217) will drive the upper top rod (218) to contact the lifting rod (216) and continuously lift the arc-shaped striking plate (214). After the upper top rod (218) and the lifting rod (216) are separated, the arc-shaped striking plate (214) will strike the conveyor belt downward through the tension of the tension spring (215) to knock out the particles stuck in the gap of the conveyor belt and to disperse the solidified impurities on the surface. Then the conveyor belt continues to move forward. At this time, the rotation of the first rotating rod (107) drives the auger rod (105) to rotate through the universal joint (108), which pulls the cleaning agent inside the collection tank (103) upward. Then, the upward pressure of the auger rod (105) causes the cleaning agent to be injected into the inside of the collection frame (223) through the hose (106). Then, the cleaning agent flows out through the flushing pipe (224) and sprays onto the top of the tape. Since the two side wall plates (204) and the baffle plate (205) wrap the three sides of the tape and the tape moves to the right, the cleaning agent flows to the right under the action of the tape. When the fourth rotating rod (219) rotates, it drives the vertical rod (210) to rotate the roller brush disc (211) through the meshing of two bevel gears (220) and the transmission of the second pulley (212) and the second belt (213). This, in conjunction with the action of the cleaning agent, washes the surface of the tape. The cleaning agent after washing flows out from the right side and the sides and falls into the inside of the liquid receiving frame (111). When the tape moves to the far right, it undergoes a second strong wash through the roller brush cylinder (203). The filter screen (113) filters the dirt, causing the cleaning agent to fall into the bottom of the liquid receiving frame (111) and be discharged back into the inside of the collection tank (103) through the return pipe (114). Then, the tape is pulled out again for cleaning using the auger rod (105). S3. After cleaning, drain the cleaning agent from the collection tank (103) and replace it with clean water. Repeat step S2 to rinse the tape until the surface is clean. After rinsing, start the cylinder (119) to push the cleaning frame (101) up and separate it from the tape. Then remove the equipment and take out the filter screen (113) for cleaning.

10. The method of using a belt conveyor cleaning device according to claim 9, characterized in that: The hose (106) in step S2 is made of elastic rubber.
