Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, specifically a belt conveyor protection device. Background Technology
[0002] A belt conveyor is a continuous transport device used for material handling. It typically consists of one or more long and wide belts, rollers, or other supporting components that run along a fixed track to transport materials from one place to another.
[0003] In the existing technology, since belt conveyors can transport a wide variety of products, when the belt conveyor is transporting products with relatively high temperatures, the conveyor belt will gradually heat up. When the temperature is too high, it will affect the normal operation of the belt conveyor.
[0004] Furthermore, products on belt conveyors are prone to leaving waste residue, which will remain on the surface of the conveyor belt. Over time, this accumulation will cause the surface of the conveyor belt to become rough, affecting the conveying effect and speed, and may even damage the conveyor belt, increasing the company's production costs. Utility Model Content
[0005] This invention provides a protective device for belt conveyors to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor protection device, comprising a conveying structure, wherein a cooling structure is provided at the top of the conveying structure, and an active cleaning structure and a passive cleaning structure are provided at the bottom of the conveying structure;
[0007] The conveying structure includes a support frame, an inner plate is fixedly installed on the inner side of the support frame, a drive motor is provided at the bend of the inner plate, and two drive shafts are rotatably connected to the inner side of the support frame. The drive shaft on the left is connected to the drive motor by a drive belt, and the two drive shafts are connected by a conveyor belt.
[0008] The cooling structure includes a mounting frame, the bottom of which is fixedly mounted to the top of a support frame via a support rod. A placement plate is fixedly connected to the inner side of the mounting frame, and a servo motor is fixedly mounted on the top of the placement plate via a mounting bracket. A fan blade is fixedly mounted on the output shaft of the servo motor.
[0009] Furthermore, a protective net is provided on the inner side of the mounting frame, and the protective net is located above the fan blades.
[0010] Furthermore, the active cleaning structure includes an abutment roller, on the outer side of which a connecting bearing and a pull-out back clamp are movably sleeved. The connecting bearing is located in front of the pull-out back clamp, and both the connecting bearing and the pull-out back clamp are fixedly connected to the inner side of the support frame. The top end of the abutment roller overlaps with the bottom end of the conveyor belt.
[0011] Furthermore, the front side of the contact roller is movably connected to a transmission column via a snap-fit pin, and the transmission column is connected to the drive motor via a transmission belt.
[0012] Furthermore, the passive cleaning structure includes two inverted blocks, with a connecting horizontal plate fixedly installed between the two inverted blocks, and both inverted blocks are fixedly connected to the inner side of the support frame.
[0013] Furthermore, a scraper is movably engaged with the outer side of the connecting cross plate, and the top of the scraper overlaps with the bottom end of the conveyor belt.
[0014] Compared with the prior art, the present invention provides a protective device for a belt conveyor, which has the following advantages:
[0015] 1. This belt conveyor protection device, by setting up a cooling structure, utilizes multiple servo motors installed on the inner side of the mounting frame to drive the fan blades to rotate at high speed, thereby causing the fan blades to begin cooling the high-temperature conveyed material on the conveyor structure. This allows the heat emitted by the high-temperature conveyed material to be quickly carried away, preventing the conveyor belt from being damaged due to excessive temperature, and effectively improving the service life and stability of the belt conveyor.
[0016] 2. This belt conveyor protection device incorporates both active and passive cleaning structures. The active cleaning structure uses a drive motor to rotate the contact rollers, which have a large contact area with the conveyor belt, resulting in significant cleaning effectiveness without damaging the conveyor belt. Simultaneously, the passive cleaning structure utilizes the relative displacement between the conveyor belt and the scraper to move the scraper, which can remove stubborn waste that is difficult to clean from the conveyor belt. This reduces the frequency of manual cleaning, improves work efficiency, and prevents long-term accumulation of waste that could damage the conveyor belt. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model discloses a protective device for a belt conveyor, including a conveying structure 1, a cooling structure 2 at the top of the conveying structure 1, and an active cleaning structure 3 and a passive cleaning structure 4 at the bottom of the conveying structure 1.
[0025] The conveying structure 1 includes a support frame 101, an inner plate 102 is fixedly installed on the inner side of the support frame 101, a drive motor 103 is provided at the bend of the inner plate 102, and two drive shafts 104 are rotatably connected to the inner side of the support frame 101. The drive shaft 104 on the left is connected to the drive motor 103 by a drive belt, and the two drive shafts 104 are connected by a conveyor belt 105.
[0026] The cooling structure 2 includes a mounting frame 202. The bottom end of the mounting frame 202 is fixedly installed to the top end of the support frame 101 via a support rod 201. A placement plate 203 is fixedly connected to the inner side of the mounting frame 202. A servo motor 204 is fixedly installed on the top end of the placement plate 203 via a mounting bracket 205. A fan blade 206 is fixedly installed on the output shaft of the servo motor 204.
[0027] The active cleaning structure 3 includes an abutment roller 301. A connecting bearing 302 and a pull-out back clip 305 are movably sleeved on the outer side of the abutment roller 301. The connecting bearing 302 is located on the front side of the pull-out back clip 305. Both the connecting bearing 302 and the pull-out back clip 305 are fixedly connected to the inner side of the support frame 101. The top end of the abutment roller 301 overlaps with the bottom end of the conveyor belt 105.
[0028] Specifically, a protective net 207 is provided on the inner side of the mounting bracket 205, and the protective net 207 is located above the fan blade 206.
[0029] In this embodiment, by setting up a protective net 207, the servo motor 204 and the fan blade 206 can be well protected, preventing the fan blade 206 from rolling in external impurities or particles during rotation, which would damage the servo motor 204 and the fan blade 206, thus improving the safety and practicality of the belt conveyor protection device.
[0030] Specifically, the front side of the abutting roller 301 is movably engaged with a transmission column 304 via a plug pin 303, and the transmission column 304 is connected to the drive motor 103 via a transmission belt.
[0031] In this embodiment, the insertion pin 303 can be used to separate the contact roller 301 from the transmission column 304, thereby facilitating the worker to remove the insertion pin 303 from the connecting bearing 302 and the pull-out back clip 305, thus facilitating the worker to replace the contact roller 301, thereby ensuring that the contact roller 301 is always in a state of efficient cleaning.
[0032] Specifically, the passive cleaning structure 4 includes two inverted blocks 401, a connecting horizontal plate 402 is fixedly installed between the two inverted blocks 401, both inverted blocks 401 are fixedly connected to the inner side of the support frame 101, and a scraping plate 403 is movably engaged on the outer side of the connecting horizontal plate 402, the top end of the scraping plate 403 overlaps with the bottom end of the conveyor belt 105.
[0033] In this embodiment, the scraper 403 is made of wear-resistant material, possessing excellent durability and corrosion resistance. It maintains a sharp scraping effect for extended periods and is not easily worn down by waste residue on the conveyor belt 105. Simultaneously, the scraper 403 has a slight chamfer at its bottom, which allows for slight polishing of the conveyor belt 105 surface while scraping away waste residue, further improving the conveying efficiency and speed of the conveyor belt 105. Furthermore, the height of the scraper 403 can be adjusted using the adjusting screws on the connecting cross plate 402 to accommodate conveyor belts 105 of different thicknesses and materials, enhancing the applicability and flexibility of this belt conveyor protection device.
[0034] In operation, when the belt conveyor starts running, the drive motor 103 starts immediately, transmitting power to the drive shaft 104 on the left side via the transmission belt, causing it to rotate. The rotation of the drive shaft 104 then causes the conveyor belt 105 to drive the drive shaft 104 on the right side to rotate synchronously, thus enabling the drive shaft 104 to drive the conveyor belt 105 for transmission. This series of power transmissions drives the conveyor belt 105 to move the product, realizing the material conveying.
[0035] Meanwhile, the contact roller 301 also begins to rotate under the drive of the drive motor 103. It makes close contact with the bottom surface of the conveyor belt 105, and through this contact, the contact roller 301 can effectively clean the waste and particles on the conveyor belt 105. The scraper plate 403 uses the movement of the conveyor belt 105 itself to form a relative displacement with it, scraping off the stubborn waste on the conveyor belt 105, ensuring the cleanliness and efficient operation of the conveyor belt 105, thereby ensuring the smooth operation of the entire conveying system.
[0036] When cooling of the product and conveyor belt 105 is required, the servo motor 204 starts, driving the fan blades 206 to rotate at high speed. The high-speed rotation of the fan blades 206 generates a strong airflow to cool the hot conveyed material on the conveyor belt 105. This cooling measure can effectively prevent the conveyor belt 105 from being damaged due to excessive temperature, extend the service life of the conveyor belt 105, and ensure the safe and stable operation of the entire conveying system.
[0037] In summary, this belt conveyor protection device, by setting up a cooling structure 2, utilizes multiple servo motors 204 installed on the inner side of the mounting frame 202 and the placement plate 203 to drive the fan blades 206 to rotate at high speed, thereby causing the fan blades 206 to begin cooling the high-temperature conveyed material on the conveying structure 1. This allows the heat emitted by the high-temperature conveyed material to be quickly carried away, preventing the conveyor belt 105 from being damaged due to excessive temperature, and effectively improving the service life and stability of the belt conveyor.
[0038] By setting up an active cleaning structure 3 and a passive cleaning structure 4, the active cleaning structure 3 uses a drive motor 103 to drive the contact roller 301 to rotate. The contact roller 301 has a large contact surface with the conveyor belt 105, resulting in a significant cleaning effect without damaging the conveyor belt 105. At the same time, the passive cleaning structure 4 uses the movement of the conveyor belt 105 itself to move relative to the scraper 403. The scraper can scrape off stubborn waste that is difficult to clean from the conveyor belt 105, reducing the frequency of manual cleaning, improving work efficiency, and avoiding damage to the conveyor belt 105 caused by long-term accumulation of waste.
[0039] It should be noted that the specific models and specifications of the drive motor 103 and servo motor 204 in the belt conveyor protection device need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0040] Furthermore, the power supply and operating principle of the drive motor 103 and servo motor 204 in the belt conveyor protection device are clear to those skilled in the art, and will not be described in detail here.
[0041] Furthermore, the working principle and wiring method of the drive motor 103 and servo motor 204 in the belt conveyor protection device are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
