Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor belt adjustment technology in mixing plants, specifically an automatic adjustment device for preventing conveyor belt deviation in mixing plants. Background Technology
[0002] In the field of construction engineering, the mixing plant conveyor belt is the core conveying equipment connecting the raw material storage areas such as sand, gravel, cement, and aggregates with the mixing host. It drives the conveyor belt to circulate through roller shaft transmission, realizing the continuous and efficient transfer of raw materials. It is a key link to ensure the smooth production process of the mixing plant. If the conveyor belt deviates during operation, the material will fall off the surface of the conveyor belt, which will directly lead to the stagnation of the mixing plant production.
[0003] Existing anti-deviation adjustment devices mostly use a single lead screw or a non-reverse threaded lead screw to drive the adjustment components. Such structures make it difficult to achieve symmetrical opposing movement of the adjustment rollers. During the correction process, it is easy for the adjustment force on one side to be too large or the adjustment direction to be unbalanced. This results in a slight deviation still existing after the conveyor belt deviation correction, making it impossible to accurately balance the tension difference on both sides of the conveyor belt, which in turn repeatedly causes deviation.
[0004] Therefore, this utility model provides an automatic adjustment device for preventing conveyor belt deviation in a mixing plant to solve the above-mentioned problems. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] This utility model provides an automatic adjustment device for preventing conveyor belt deviation in a mixing plant, which aims to solve the problems mentioned in the background art.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] An automatic adjustment device for preventing conveyor belt deviation in a mixing plant includes a conveyor belt body and an adjustment mechanism, wherein the adjustment mechanism is telescopically installed on both sides inside the conveyor belt body.
[0010] Rollers are installed on both sides of the conveyor belt body, drive motors are fixedly installed on the surface of the rollers, and a fixing plate is fixedly installed on one side of the roller surface.
[0011] The adjustment mechanism includes a guide rail, a lead screw rotatably mounted on the surface of the guide rail, a limit block fixedly mounted at the center of the lead screw surface, sliders threadedly connected to both sides of the lead screw surface, a support plate fixedly mounted on the top of the sliders, and an adjustment roller sleeved on the top of the support plate.
[0012] When the conveyor belt deviates from its designated path, the rotation of the lead screw drives the sliders on both sides to move in the opposite direction along the guide rail. This, in turn, drives the adjusting rollers via the support plate to precisely adjust their position, achieving automatic and rapid correction of the conveyor belt deviation. This reduces the risk of material spillage, equipment wear, and other malfunctions caused by the conveyor belt deviation, ensuring the continuity and stability of material conveying in the mixing plant. The limiting block at the center of the lead screw effectively restricts the movement range of the sliders on both sides, improving the safety and reliability of the adjusting mechanism. Meanwhile, the structure of the adjusting rollers sleeved on the top of the support plate can adapt to the dynamic tension changes of the conveyor belt during operation, reducing rigid friction between the adjusting rollers and the conveyor belt.
[0013] As a preferred technical solution of this application, a groove is provided on the upper part of the surface of the fixed plate, and a servo motor is fixedly installed at the bottom of the groove. The groove facilitates the adjustment roller to slide and adjust on both sides of the surface of the conveyor belt body, thereby adjusting the curvature of both sides of the surface of the conveyor belt body and preventing materials from falling off the sides of the surface of the conveyor belt body.
[0014] As a preferred technical solution of this application, the inside of the groove corresponds to the surface of the adjusting roller, which can avoid spatial interference between the groove and the adjusting roller, and ensure that the adjusting roller will not rub or collide with the inner wall of the groove during the left and right adjustment process, thus ensuring the smooth operation of the adjusting mechanism.
[0015] As a preferred technical solution of this application, there are two lead screws, and the surfaces of the two lead screws are threaded. The threads on the surfaces of the two lead screws are reverse threads. The two lead screws are separated by a limit block. Through the reverse thread characteristics, the sliders on both sides drive the adjusting roller to achieve symmetrical opposite movement, which improves the symmetry and balance of deviation correction and avoids the problem of over-adjustment on one side that is easy to occur when adjusting a single lead screw.
[0016] As a preferred technical solution of this application, the servo motor starts and drives the two lead screws to rotate. Through the reverse thread, the adjusting roller slides in opposite directions at the top of the two lead screws. The reverse thread is converted into precise opposite sliding of the adjusting roller, so that the displacement of the adjusting roller can be precisely controlled. The opposite sliding adjustment method allows the adjusting rollers on both sides of the conveyor belt to generate opposite adjustment forces synchronously, quickly balance the tension difference on both sides of the conveyor belt, and avoid material spillage due to untimely correction.
[0017] As a preferred technical solution of this application, the adjusting rollers are inclined and contact both sides of the surface of the conveyor belt body, causing both sides of the surface of the conveyor belt body to tilt upward. When the conveyor belt body deviates, the inclined adjusting rollers can generate lateral guiding force on the edge of the conveyor belt body, guiding the conveyor belt body to return to the center. At the same time, it causes both sides of the conveyor belt body to tilt upward, forming a slightly arc-shaped support structure that is low in the middle and high on both sides. By utilizing the gravity of the material itself, it prevents the material from sliding to both sides during the conveying process and reduces material waste.
[0018] As a preferred technical solution of this application, the adjusting rollers are evenly distributed on both sides of the surface of the conveyor belt body. When slight deviation occurs in different sections of the conveyor belt body, the adjusting rollers at the corresponding positions can respond in time and perform local correction, thereby improving the comprehensiveness and timeliness of the overall deviation correction and preventing local deviation from spreading into overall deviation.
[0019] (III) Beneficial Effects
[0020] Two opposing threaded lead screws are separated by a limit block. Driven by a servo motor, they can drive the adjusting roller to achieve symmetrical opposite movement. This not only improves the symmetry and balance of deviation correction and avoids excessive adjustment on one side, but also quickly balances the tension difference on both sides of the conveyor belt body by precisely controlling the displacement of the adjusting roller, thus reducing material spillage.
[0021] The adjusting rollers, which are inclined and in contact with both sides of the conveyor belt body, can generate lateral guiding force to guide the conveyor belt to reset and form an arc-shaped support structure that is low in the middle and high on both sides. They prevent slippage by using the gravity of the material. The even distribution of the adjusting rollers on both sides of the conveyor belt can promptly and locally correct slight deviations in different sections, improving the comprehensiveness and timeliness of the correction and preventing local deviations from spreading into overall deviations.

[0029] 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.
[0030] This utility model provides an automatic adjustment device for preventing conveyor belt deviation in a mixing plant, such as... Figure 1-4 As shown, it includes a conveyor belt body 100 and an adjustment mechanism 200, which is telescopically installed on both sides inside the conveyor belt body 100.
[0031] Rollers 101 are installed on both sides of the surface of the conveyor belt body 100. A drive motor 102 is fixedly installed on the surface of the roller 101. A fixing plate 103 is fixedly installed on one side of the surface of the roller 101.
[0032] The adjustment mechanism 200 includes a guide rail 201, a lead screw 202 rotatably mounted on the surface of the guide rail 201, a limit block 203 fixedly mounted at the center of the surface of the lead screw 202, sliders 204 threadedly connected to both sides of the surface of the lead screw 202, a support plate 205 fixedly mounted on the top of the sliders 204, and an adjustment roller 206 sleeved on the top of the support plate 205.
[0033] When the conveyor belt body 100 deviates from its designated path, the rotation of the lead screw 202 drives the sliders 204 on both sides to move in the opposite direction along the guide rail 201. This, in turn, drives the adjusting roller 206 to precisely adjust its position via the support plate 205, achieving automatic and rapid correction of the conveyor belt body 100's deviation. This reduces the risk of material spillage, equipment wear, and other malfunctions caused by the conveyor belt body 100's deviation, ensuring the continuity and stability of material conveying in the mixing plant. The limiting block 203 at the center of the lead screw 202 effectively limits the movement range of the sliders 204 on both sides, improving the safety and reliability of the adjusting mechanism 200. At the same time, the structure of the adjusting roller 206 sleeved on the top of the support plate 205 can adapt to the dynamic tension changes during the operation of the conveyor belt body 100, reducing the rigid friction between the adjusting roller 206 and the conveyor belt body 100.
[0034] like Figure 1 and Figure 4As shown, a groove 104 is provided on the upper part of the surface of the fixed plate 103. A servo motor 207 is fixedly installed at the bottom of the groove 104. The groove 104 facilitates the sliding adjustment of the adjusting roller 206 on both sides of the surface of the conveyor belt body 100, so as to adjust the curvature of both sides of the surface of the conveyor belt body 100 and prevent materials from falling off the sides of the surface of the conveyor belt body 100.
[0035] like Figure 1-4 As shown, the interior of the groove 104 corresponds to the surface of the adjusting roller 206, which can avoid spatial interference between the groove 104 and the adjusting roller 206, and ensure that the adjusting roller 206 will not rub or collide with the inner wall of the groove 104 during the left and right adjustment process, thus ensuring the smooth operation of the adjusting mechanism 200.
[0036] like Figure 2-3 As shown, there are two lead screws 202. The surfaces of the two lead screws 202 are threaded, and the threads on the surfaces of the two lead screws 202 are reverse threads. The two lead screws 202 are separated by a limit block 203. Through the reverse thread characteristics, the sliders 204 on both sides drive the adjusting rollers 206 to achieve symmetrical opposing movements, which improves the symmetry and balance of deviation correction and avoids the problem of over-adjustment on one side that is easy to occur when adjusting a single lead screw 202.
[0037] like Figure 2-4 As shown, the servo motor 207 starts, driving the two lead screws 202 to rotate. Through the reverse thread, the adjusting roller 206 slides in opposite directions at the top of the two lead screws 202. The reverse thread is converted into precise opposing sliding of the adjusting roller 206, so that the displacement of the adjusting roller 206 can be precisely controlled. The opposing sliding adjustment method allows the adjusting rollers 206 on both sides of the conveyor belt body 100 to generate opposing adjustment forces synchronously, quickly balancing the tension difference on both sides of the conveyor belt body 100 and avoiding material spillage due to untimely correction.
[0038] like Figure 2 and Figure 4 As shown, the adjusting rollers 206 are inclined and contact both sides of the surface of the conveyor belt body 100, causing both sides of the surface of the conveyor belt body 100 to tilt upward. When the conveyor belt body 100 deviates from its course, the inclined adjusting rollers 206 can generate a lateral guiding force on the edge of the conveyor belt body 100, guiding the conveyor belt body 100 back to the center. At the same time, it causes both sides of the conveyor belt body 100 to tilt upward, forming a slightly arc-shaped support structure that is low in the middle and high on both sides. By utilizing the weight of the material itself, it prevents the material from slipping to both sides during the conveying process and reduces material waste.
[0039] like Figure 1As shown, the adjusting rollers 206 are evenly distributed on both sides of the surface of the conveyor belt body 100. When slight deviation occurs in different sections of the conveyor belt body 100, the adjusting rollers 206 at the corresponding positions can respond in time and perform local correction, thereby improving the comprehensiveness and timeliness of the overall deviation correction and preventing local deviation from spreading into overall deviation.
[0040] In summary: The conveyor belt body 100 conveys materials through the transmission of rollers 101 on both sides, and the rollers 101 are powered by the drive motor 102. When the conveyor belt body 100 deviates from its designated path, the servo motor 207 installed at the bottom of the groove 104 of the fixing plate 103 is activated. The servo motor 207 drives the two reverse-threaded lead screws 202 on the surface of the guide rail 201 in the adjusting mechanism 200 to rotate synchronously. Since the lead screws 202 have reverse threads on both sides, their rotation will drive the surface threaded slider 204 to move along the guide rail 201. As the slider moves symmetrically in opposite directions, the support plate 205 at the top of the slider 204 moves synchronously with the slider 204, thereby driving the adjusting roller 206 sleeved on the top of the support plate 205 to precisely adjust its position. At this time, the adjusting roller 206, which is inclined and in contact with both sides of the conveyor belt body 100, generates a lateral guiding force on the edge of the conveyor belt body 100, guiding the deviated conveyor belt body 100 back to the center. On the other hand, it drives both sides of the conveyor belt body 100 to tilt upward, forming an arc-shaped support structure that is low in the middle and high on both sides to prevent materials from slipping.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
