Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, specifically relating to a protective device to prevent materials from entering the return side of a belt conveyor. Background Technology

[0002] Belt conveyors are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for the assembly, testing, debugging, packaging, and transportation of items. They have strong conveying capacity, long conveying distance, simple structure, and are easy to maintain. They can be easily programmed and automated. They use the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100 kilograms or powdery or granular items. They run at high speed, smoothly, and with low noise, and can convey items uphill and downhill.

[0003] When belt conveyors transport highly viscous materials, the materials can adhere to the surface of the conveyor belt and enter the return side of the belt, causing damage to the internal structure of the belt conveyor. Although existing belt conveyors have cleaning devices, their effectiveness is poor and they cannot clean up the adhered materials. Furthermore, the cleaning devices of existing belt conveyors are not adjustable and are always in contact with the surface of the conveyor belt, which can easily reduce the service life of the conveyor belt. Therefore, we propose a protective device to prevent materials from entering the return side of the belt conveyor. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This protective device for preventing materials from entering the return side of the belt conveyor is equipped with a vibration structure and a scraping structure. When materials are transported by the conveyor belt and adhere to the surface of the conveyor belt, motor two is turned on, which drives the cam group to rotate. One end of the connecting rod moves with the cam group, and the other end pulls the connecting block to move through the rotating shaft. This causes the slider one at the top of the connecting block to move up and down, which in turn drives the vibrating roller to move back and forth vertically on the surface of the conveyor belt, shaking off the materials adhering to the surface of the conveyor belt. The spring also acts as a buffer. Under the action of spring two, slider two is pushed upward, and then the crossbar presses the scraper on the surface of the conveyor belt to scrape off the materials that have not been shaken off. By first vibrating and then scraping, the materials adhering to the surface of the conveyor belt are cleaned, preventing the materials from entering the return side of the belt conveyor and causing damage to the internal devices.

[0014] 2. This protective device for preventing materials from entering the return side of the belt conveyor is equipped with a limiting structure. When the scraper presses against the surface of the conveyor belt, spring three is in a compressed state. Pulling down the pull rod causes the crossbar to move downward. At this time, spring two is compressed, and slider two and the crossbar tend to move upward. Spring three pushes slider three to both sides, so that the top of the limiting rod contacts the bottom of the fixed column, preventing slider two and the crossbar from moving upward. This prevents the scraper from contacting the surface of the conveyor belt. The contact between the scraper and the conveyor belt can be adjusted as needed to avoid the scraper always contacting the conveyor belt and increase the service life of the conveyor belt.

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A protective device to prevent materials from entering the return side of a belt conveyor includes a belt conveyor body 1. The belt conveyor body 1 includes a conveyor belt 2 and a motor 3. The motor 3 is fixedly connected to the surface of the belt conveyor body 1. A drive roller is fixedly connected to the output end of the motor 3. The conveyor belt 2 is disposed on the surface of the drive roller. A support frame 4 is fixedly connected to the bottom of the belt conveyor body 1. The support frame 4 includes a support column group one near the motor 3 and a support column group two away from the motor 3. A vibration structure 5 is provided inside the support column group two. The vibration structure 5 includes a motor 51. A cam group 52 is fixedly connected to the output end of the motor 51. The cam group 52 includes two sets of cams and a fixed shaft. A connecting shaft 53 is fixedly connected to the surface of the cams, and a connecting shaft 53 is fixedly connected to the surface of the fixed shaft. There is a connecting rod 54, and a rotating shaft 55 is movably connected inside the connecting rod 54. A connecting block 56 is fixedly connected to the surface of the rotating shaft 55. A slider 57 is fixedly connected to the top of the connecting block 56. A spring 58 is fixedly connected to the top of the slider 57. A vibrating roller 59 is movably connected inside the slider 57. A scraping structure 6 is fixedly connected to the bottom of the belt conveyor body 1. The scraping structure 6 includes a fixed column 61. An auxiliary roller 62 is rotatably connected inside the fixed column 61. A slider 63 is movably connected inside the fixed column 61. A spring 64 is fixedly connected to the bottom of the slider 63. A crossbar 65 is fixedly connected to the surface of the slider 63. A scraper 66 is fixedly connected to the surface of the crossbar 65. A pull rod 67 is fixedly connected to the bottom of the crossbar 65. The part is equipped with a limiting structure 7, which includes a slider 3 71. The bottom of the slider 3 71 is fixedly connected to a limiting rod 72. A lever 73 is fixedly connected to the surface of the limiting rod 72. A spring 3 74 is fixedly connected to the surface of the slider 3 71. A vibration structure 5 and a scraping structure 6 are set up. The material is transported by the conveyor belt 2. When the material sticks to the surface of the conveyor belt 2, the motor 2 51 is turned on, which drives the cam group 52 to rotate. One end of the connecting rod 54 moves with the cam group 52, and the other end pulls the connecting block 56 to move through the rotating shaft 55. This causes the slider 1 57 on the top of the connecting block 56 to move up and down, which in turn drives the vibrating roller 59 to move back and forth on the surface of the conveyor belt 2, shaking off the material sticking to the surface of the conveyor belt 2. The spring 1 58 plays a buffering role, while the spring 2 6 Under the action of 4, slider 2 63 is pushed upward, and then the scraper 66 is pressed against the surface of conveyor belt 2 by the crossbar 65, scraping off the material that has not been shaken off. By vibrating first and then scraping, the material adhering to the surface of conveyor belt 2 is cleaned, preventing the material from entering the return side of the belt conveyor and causing damage to the internal devices. A limiting structure 7 is set. When the scraper 66 is pressed against the surface of conveyor belt 2, spring 3 74 is in a compressed state, pulling the pull rod 67 downward, causing the crossbar 65 to move downward. At this time, spring 2 64 is compressed, and slider 2 63 and crossbar 65 have an upward tendency. Spring 3 74 pushes slider 3 71 to both sides, so that the top of the limiting rod 72 contacts the bottom of the fixed column 61, preventing slider 2 63 and crossbar 65 from moving upward.This prevents the scraper 66 from contacting the surface of the conveyor belt 2. The contact between the scraper 66 and the conveyor belt 2 can be adjusted as needed to avoid constant contact and increase the service life of the conveyor belt 2.

[0024] Furthermore, the support column group two has a square cavity inside. The cam group 52, connecting rod 54, rotating shaft 55, connecting block 56 and slider 57 are all movably connected in the square cavity. A circular groove is opened at the top of the square cavity. One end of spring 58 is fixedly connected to the inner wall of the circular groove, and the other end of spring 58 is fixedly connected to the top of slider 57. When the vibrating roller 59 moves back and forth in the vertical direction on the surface of the conveyor belt 2 to shake off the material adhering to the surface of the conveyor belt 2, spring 58 plays a certain buffering role on the vibrating roller 59.

[0025] Furthermore, the two ends of the fixed shaft are respectively fixedly connected to two sets of cams. One end of the connecting rod 54 is sleeved on the surface of the fixed shaft, and the other end of the connecting rod 54 is sleeved on the surface of the rotating shaft 55. Two sets of connecting blocks 56 are symmetrically arranged, and the two sets of connecting blocks 56 are respectively fixed at both ends of the rotating shaft 55. The cam group 52, connecting rod 54, rotating shaft 55, connecting block 56, slider 57 and spring 58 are symmetrically arranged in two sets about the connecting shaft 53. The motor 51 drives the cam group 52 to rotate. One end of the connecting rod 54 moves with the cam group 52, and the other end pulls the connecting block 56 to move through the rotating shaft 55, so that the slider 57 on the top of the connecting block 56 moves up and down, thereby driving the vibrating roller 59 to move back and forth on the surface of the conveyor belt 2.

[0026] Furthermore, two sets of fixed columns 61, sliders 63 and springs 64 are symmetrically arranged. The surfaces of the two sets of fixed columns 61 are provided with circular grooves. The two ends of the auxiliary roller 62 are rotatably connected in the circular grooves, and the surface of the auxiliary roller 62 is in contact with the surface of the conveyor belt 2.

[0027] Furthermore, slider 63 is T-shaped, and the surface of fixed column 61 is provided with sliding groove 1 that matches slider 63. Sliding slider 63 is slidably connected in sliding groove 1. The bottom of sliding groove 1 is provided with circular groove 3. One end of spring 64 is fixedly connected to the inner wall of circular groove 3, and the other end of spring 64 is fixedly connected to the bottom of slider 63. Scraper 66 is triangular. Under the action of spring 64, slider 63 is pushed upward, and then the crossbar 65 presses scraper 66 onto the surface of conveyor belt 2 to scrape off the material that has not been shaken off.

[0028] Furthermore, the limiting structure 7 is symmetrically arranged with two sets about the crossbar 65. The slider 3 71 is T-shaped. The surface of the crossbar 65 is provided with two sets of sliding grooves 2 that match the slider 3 71. The slider 3 71 is slidably connected in the sliding grooves 2. The slider 3 71 is restricted to moving only in the horizontal direction by the cooperation between the slider 3 71 and the sliding grooves 2.

[0029] Furthermore, a circular groove four is provided on one side of the sliding groove two. One end of the spring three 74 is fixedly connected to the inner wall of the circular groove four, and the other end of the spring three 74 is fixedly connected to the slider three 71. The limiting rod 72 is L-shaped. Pulling the pull rod 67 downward causes the crossbar 65 to move downward. The spring three 74 pushes the slider three 71 to both sides, so that the top of the limiting rod 72 contacts the bottom of the fixed column 61.

[0030] Working principle: The material is transported by the conveyor belt 2. When the material adheres to the surface of the conveyor belt 2, the motor 51 is turned on, which drives the cam assembly 52 to rotate. One end of the connecting rod 54 moves with the cam assembly 52, and the other end pulls the connecting block 56 through the rotating shaft 55. This causes the slider 57 on the top of the connecting block 56 to move up and down, which in turn drives the vibrating roller 59 to move back and forth on the surface of the conveyor belt 2, shaking off the material adhering to the surface of the conveyor belt 2. The spring 58 acts as a buffer, while the slider 63 is pushed by the spring 64. Pushing it up, the crossbar 65 presses the scraper 66 against the surface of the conveyor belt 2, scraping off any material that has not been shaken off. When the scraper 66 is no longer needed, pull the lever 67 down, causing the crossbar 65 to move downward. At this time, the second spring 64 is compressed, and the second slider 63 and the crossbar 65 tend to move upward. The third spring 74 pushes the third slider 71 to both sides, so that the top of the limiting rod 72 contacts the bottom of the fixed column 61, preventing the second slider 63 and the crossbar 65 from moving upward, thus preventing the scraper 66 from contacting the surface of the conveyor belt 2.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
