However, the cleaning effect and efficiency of the device are poor. Utility Model Content

[0003] The purpose of the utility model is to provide a powder coating dust removal device to solve the above-mentioned technical problems, which can fully clean the surface of the conveyor belt and has a good cleaning effect.

[0004] In view of this, the utility model provides a powder coating dust removal device, including a conveying mechanism, and also includes:

[0005] A cleaning device, the cleaning device comprising a scraping structure capable of abutting against a surface of a conveyor belt, a cleaning brush body for cleaning the surface of the conveyor belt, and a propulsion mechanism capable of controlling the scraping structure and the cleaning brush body to approach and abut against a conveyor mechanism below;

[0006] A lifting device is arranged at both ends of the conveying mechanism in the width direction. The lifting device acts on both ends of the cleaning device to control the cleaning device to be close to the conveying mechanism below.

[0007] In the present technical solution, the coating powder is transferred through the conveying mechanism during the production process, and the lifting devices arranged at both ends of the conveying mechanism support the cleaning device. When the conveying mechanism performs production work, the lifting device controls the cleaning device to stay away from the conveying mechanism below to avoid interfering with the normal transportation of the conveying mechanism. When it is necessary to clean and dust the conveyor belt on the surface of the transmission mechanism, the lifting device can control the cleaning device from both ends to make it close to the conveying mechanism below. After the lifting device controls the cleaning device to the specified position, the propulsion mechanism controls the scraping structure and the cleaning brush body to contact the surface of the conveyor belt to perform cleaning work.

[0008] In the above technical solution, further, the propulsion mechanism is a first hydraulic cylinder, the first hydraulic cylinder is fixedly connected to the top of the fixed plate, the output end of the first hydraulic cylinder passes through the fixed plate and is fixedly connected to the top of the mounting plate, a scraping structure and a cleaning brush body are provided on the mounting plate, and both ends of the fixed plate are connected to the lifting device.

[0009] In this technical solution, the working direction of the output end of the first hydraulic rod is the vertical direction, and it passes through the fixed plate to control the mounting plate. When the conveying component needs to be cleaned, the output end of the first hydraulic rod pushes the mounting plate close to the conveyor belt below until the scraping structure and cleaning brush body on the mounting plate are in contact with the conveyor belt for cleaning.

[0010] In the above technical solution, further, the scraping structure includes a support plate with two ends arranged on the mounting plate, and a plurality of scraping units extending downward are equidistantly arranged on the support plate. There are at least two support plates and they are arranged front and back, and the scraping units arranged on the front and rear support plates are staggered.

[0011] In this technical solution, both ends of the support plate are fixedly connected to the mounting plate by bolts. In this embodiment, there are two support plates arranged front and back, and the scraping units arranged on the front and rear support plates are staggered, which can facilitate the scraped material to pass through the scraping structure smoothly after scraping along the conveyor belt.

[0012] In the above technical solution, further, the scraping unit is a "V"-shaped plate, one end of which is fixedly connected to the support plate, and the other end extends toward the conveyor belt, with the tip facing the direction of material conveying of the conveyor belt.

[0013] In this technical solution, the materials adhered to the conveyor belt are scraped off by the scraping unit and then move backward along the two sides of the "V"-shaped plate.

[0014] In the above technical solution, further, the cleaning brush body is a roller structure with a cleaning brush, and the cleaning brush body is rotatably connected to a mounting plate, a first motor is fixedly provided on one side of the mounting plate, and an output end of the first motor passes through the mounting plate and is coaxially fixedly connected to the cleaning brush body.

[0015] In the present technical solution, the side wall of the mounting plate is "L"-shaped. When the scraping unit conflicts with the conveyor belt, the cleaning brush body is located at the end of the conveyor belt, and is used to brush off the scraping structure to scrape the material adhered to the conveyor belt. The first motor drives the cleaning brush body to rotate synchronously, and drives the brush fixed on the cleaning brush body to sweep off the scraped material.

[0016] In the above technical solution, further, it also includes a scraper plate, which includes arms symmetrically arranged on the inner side of the side wall of the mounting plate, the arms extending toward the cleaning brush body, and a scraper plate is fixedly connected between the two arms, and the scraper plate can contact the cleaning brush body.

[0017] In the present technical solution, the arms on both sides of the scraper plate are fixedly connected to the inner side of the side wall of the mounting plate by bolts, and can be disassembled and the angle can be adjusted. When the cleaning brush body and the scraping structure scrape the material adhered to the conveyor belt, at least a small amount of material impurities will adhere to the cleaning brush body. When the cleaning brush on the cleaning brush body contacts the scraper plate of the scraper plate when the cleaning brush body rotates, the scraper plate can scrape off the dust or material adhered to the cleaning brush body, thereby ensuring the cleaning effect of the cleaning brush body.

[0018] In the above technical solution, further, the rotation direction of the cleaning brush body is opposite to the conveying direction of the conveyor belt.

[0019] In this technical solution, the materials and dust on the conveyor belt can be better swept away, and the scraper plate can also better cooperate with the scraper plate to scrape away the dust or materials adhering to the cleaning brush body, ensuring that the dust scraped by the scraper plate falls downward.

[0020] In the above technical scheme, further, a lifting device is provided, which includes a support frame fixedly arranged on the support structure at both ends of the conveyor belt, the support frame is a hollow structure, a screw rod is arranged in one support frame, and a sliding rod is arranged in the other support frame, a slider is slidably arranged on the screw rod and the sliding rod, the slider is fixedly connected with a connecting rod, the connecting rod is fixedly connected through a slide groove and a fixed plate, the screw rod is coaxially fixedly connected with a first bevel gear, the first bevel gear is meshed with a second bevel gear, and the second bevel gear is coaxially fixedly connected with a second motor.

[0021] In the present technical solution, the second motor rotates, and the second bevel gear coaxially fixedly connected to the output end of the second motor meshes with the first bevel tooth, driving the lead screw coaxially fixedly connected to the first bevel tooth to rotate, and the slider threadedly connected to the lead screw drives the cleaning assembly to move upward or downward through the connecting rod. The slide rod plays a role of limiting and guiding, ensuring the stability of controlling the movement of the cleaning device. When the conveying mechanism performs production work, the lifting device controls the cleaning device to stay away from the conveying mechanism below to avoid interfering with the normal transportation of the conveying mechanism. When it is necessary to clean and dust the conveyor belt on the surface of the transmission mechanism, the lifting device can control the cleaning device from both ends to make it close to the conveying mechanism below.

[0022] The beneficial effects of the utility model are:

[0023] 1. After the cleaning structure scrapes the materials and dust adhering to the conveyor belt, the cleaning brush body acting on the end of the conveyor belt brushes off the materials and dust on the conveyor belt. The combination of the two can achieve a good dust removal effect on the surface of the conveyor belt;

[0024] 2. The cleaning structure and the cleaning brush body are set along the width direction of the conveyor belt. There is no need to move them during cleaning. Just make sure they are in contact with the surface of the conveyor belt.

[0025] 3. A scraper plate is provided. When the cleaning brush on the cleaning brush body contacts the scraper plate of the scraper plate as the cleaning brush body rotates, the scraper plate can scrape off the dust or material adhered to the cleaning brush body. BRIEF DESCRIPTION OF THE DRAWINGS
