Description

Technical Field

[0001] This utility model belongs to the field of belt scale technology, and in particular relates to a four-roller belt scale. Background Technology

[0002] With the acceleration of industrial automation and intelligentization, the accuracy and stability of material measurement have become key aspects of ensuring production efficiency, controlling costs, and improving product quality. Four-roller belt scales, as a core device commonly used for continuous measurement of bulk materials, are widely used in conveying systems in industries such as coal, power, metallurgy, and chemicals. They can perform real-time weight detection and cumulative measurement of materials transported on belt conveyors, providing important data support for production process scheduling, energy consumption analysis, and cost accounting. Their measurement performance is directly related to the scientific and economical nature of enterprise production operations. Therefore, high-precision and high-stability four-roller belt scales are needed to meet the needs of industrial production.

[0003] However, existing four-roller belt scales are not convenient for cleaning the belt surface during use, it is difficult to flexibly adjust the contact force between the cleaning components and the belt, and it is not convenient to adjust the cleaning intensity according to the degree of impurity adhesion to ensure the cleaning effect. They also cannot adapt to the different contact force requirements under various working conditions. Utility Model Content

[0004] The purpose of this utility model is to provide a four-roller belt scale. By setting up a cleaning unit, it solves the problems of existing four-roller belt scales, such as inconvenience in cleaning the belt surface during use, difficulty in flexibly adjusting the contact force between the cleaning component and the belt, inconvenience in adjusting the cleaning intensity according to the degree of impurity adhesion to ensure the cleaning effect, and inability to adapt to different contact force requirements under various working conditions.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a four-roller belt scale, comprising a support frame and a four-roller belt scale fixedly connected to the top of the support frame. A belt is fitted onto the four-roller belt scale. The scale also includes a cleaning section mounted on the support frame and located below the belt. The cleaning section comprises a cleaning assembly, which includes a hollow rectangular box fixedly connected to the support frame. One side of the hollow rectangular box has an opening. A rectangular plate extending beyond the opening of the hollow rectangular box is provided on the bottom inner wall of the hollow rectangular box. Several telescopic rods are fixedly connected to the top of the rectangular plate, and a rectangular plate (secondary) contacting the top inner wall of the hollow rectangular box is fixedly connected to the top of the telescopic rods. A portion of the rectangular plate (secondary) extends beyond the opening of the hollow rectangular box, and a cleaning plate in contact with the belt is fixedly connected to its top. An adjustment assembly is mounted on the cleaning assembly for driving the cleaning assembly to move up and down.

[0007] Furthermore, the adjustment assembly includes a slide rod fixedly connected between the inner wall of the top and the inner wall of the bottom of the hollow rectangular box. The slide rod passes through rectangular plate one and rectangular plate two respectively and is slidably connected to rectangular plate one and rectangular plate two. A threaded rod is rotatably connected to the inner wall of the top of the hollow rectangular box. The threaded rod extends downward through rectangular plate one and rectangular plate two to the outside of the hollow rectangular box. The threaded rod is threadedly engaged with rectangular plate one. A handle is fixedly connected to the end of the threaded rod.

[0008] Furthermore, it also includes a limiting part, which includes: a limiting component installed at the bottom of the hollow rectangular box to limit the rotation of the threaded rod; and an elastic component installed on the limiting component to reset the limiting component.

[0009] Furthermore, the elastic component includes a circular plate fixedly connected to the outer wall of the support rod, the circular plate being slidably connected to the inner wall of the hollow rectangular block, and a second spring being sleeved on the outer wall of the support rod, one end of the second spring being fixedly connected to the circular plate, and the other end of the second spring being fixedly connected to the inner wall of the hollow rectangular block.

[0010] Furthermore, several of the telescopic rods are provided with elastic elements, each elastic element including a spring 1 respectively sleeved on the outer wall of several telescopic rods, the top of several spring 1 being fixedly connected to a rectangular plate 2, and the bottom of several spring 1 being fixedly connected to a rectangular plate 1.

[0011] Furthermore, the support rod is provided with a limiting component, which includes an arc-shaped limiting block fixedly connected to one end of the support rod, and the arc-shaped limiting block is adapted to the ratchet gear.

[0012] The four-roller belt scale in this device is an ICS-FH-4 four-roller electronic belt scale. Its working principle is as follows: the material passes through the weighing bridge with the belt. The four sets of weighing rollers on the weighing bridge transmit the weight of the material on the belt to four high-precision shear beam type weighing sensors, generating a voltage signal proportional to the belt load. At the same time, the speed sensor is directly connected to the speed measuring roller to detect the belt running speed and output a series of pulse signals. These signals are transmitted to the integrator together. The integrator processes the weight and speed signals and obtains the instantaneous flow rate and cumulative weight value of the material through integration calculation.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a cleaning section, the cleaning plate contacts the outer wall of the belt to clean the belt surface, including removing hard objects and impurities that are stuck together. The cooperation between the telescopic rod and spring 1 makes the cleaning plate and the belt surface form an elastic contact. By turning the handle counterclockwise on the threaded rod, the rectangular plate 1 can be moved upward, squeezing the telescopic rod and spring 1 to deform and generate elastic force. The reverse operation reduces the elastic force of spring 1. Finally, the contact force between the cleaning plate and the belt surface is controlled by adjusting the elastic force of spring 1. The cleaning plate and the belt adopt an elastic contact method, which can avoid the wear of the belt or cleaning plate caused by rigid contact. The contact force between the cleaning plate and the belt can be flexibly adjusted. It can adjust the cleaning intensity according to the degree of impurity adhesion to ensure the cleaning effect, and can also adapt to the contact force requirements under various working conditions.

[0015] 2. By setting a limiting part, when the threaded rod is rotated, the threaded rod drives the ratchet to rotate synchronously. The ratchet presses the arc-shaped limiting block through the arc surface, causing the arc-shaped limiting block to drive the support rod to slide on the hollow rectangular block and move away from the ratchet. At the same time, the support rod drives the circular plate to compress the second spring, causing it to deform and generate elastic force. Under the action of the second spring, the arc-shaped limiting block will engage with the ratchet again, thus allowing the threaded rod to rotate repeatedly. Moreover, through the right-angle cooperation between the arc-shaped limiting block and the ratchet, it can be ensured that the threaded rod rotates in one direction and prevents it from reversing. If smooth rotation of the threaded rod is required, simply pull the support rod to drive the arc-shaped limiting block to disengage from the ratchet. This effectively prevents the threaded rod from rotating on its own when it is not needed, ensuring the stability of the contact force between the cleaning plate and the belt after adjustment, and avoiding the impact of accidental reverse rotation on the cleaning effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0026] Please see Figure 1-5 As shown, this utility model is a four-roller belt scale, including a support frame 111 and a four-roller belt scale 112 fixedly connected to the top of the support frame 111. A belt 113 is fitted onto the four-roller belt scale 112. It also includes a cleaning part 2, which is mounted on the support frame 111 and located below the belt. The cleaning part 2 includes a cleaning assembly 21, which includes a hollow rectangular box 211 fixedly connected to the support frame 111. One side of the hollow rectangular box 211 is open, and the bottom inner wall of the hollow rectangular box is... A rectangular plate 212 is provided, which extends beyond the opening of the hollow rectangular box. Several telescopic rods 213 are fixedly connected to the top of the rectangular plate 212. A rectangular plate 214 is fixedly connected to the top of the telescopic rods 213, which contacts the inner top wall of the hollow rectangular box. A cleaning plate 215 is fixedly connected to the top of the rectangular plate 214, which extends beyond the opening of the hollow rectangular box and contacts the belt 113. An adjustment component 22 is installed on the cleaning component 21 to drive the cleaning component to move up and down.

[0027] Four telescopic rods 213 are provided and arranged in a linear array inside the hollow rectangular box 211.

[0028] The adjustment assembly 22 includes a slide rod 221 fixedly connected between the inner top and bottom walls of the hollow rectangular box 211. The slide rod 221 passes through rectangular plate 1 and rectangular plate 2 respectively and is slidably connected to rectangular plate 1 212 and rectangular plate 2. A threaded rod 222 is rotatably connected to the inner top wall of the hollow rectangular box 211. The threaded rod 222 extends downward through rectangular plate 1 and rectangular plate 2 to the outside of the hollow rectangular box 211. The threaded rod 222 is threadedly engaged with rectangular plate 1 212. A handle 223 is fixedly connected to the end of the threaded rod 222. By setting the cleaning part 2, the cleaning plate 215 and the belt 113 adopt an elastic contact method, which can avoid the wear of the belt 113 or the cleaning plate 215 caused by rigid contact. The contact force between the cleaning plate 215 and the belt 113 can be flexibly adjusted, which can adjust the cleaning intensity according to the degree of impurity adhesion to ensure the cleaning effect, and can also adapt to the contact force requirements under various working conditions.

[0029] It also includes a limiting part, the limiting part 3 including: a limiting component 31, the limiting component 31 is installed at the bottom of the hollow rectangular box 211 to limit the rotation of the threaded rod; and an elastic component 32, the elastic component 32 is installed on the limiting component 31 to reset the limiting component.

[0030] The limiting component 31 includes a ratchet 311 fixedly connected to the outer wall of the threaded rod 222. A hollow rectangular block 312 is fixedly connected to the bottom of the hollow rectangular box 211. A support rod 313 passes through the hollow rectangular block 312 and is slidably connected to the hollow rectangular block 312.

[0031] The elastic component 32 includes a circular plate 321 fixedly connected to the outer wall of the support rod 313. The circular plate 321 is slidably connected to the inner wall of the hollow rectangular block 312. A second spring 322 is sleeved on the outer wall of the support rod 313. One end of the second spring 322 is fixedly connected to the circular plate 321, and the other end of the second spring 322 is fixedly connected to the inner wall of the hollow rectangular block 312.

[0032] Several telescopic rods 213 are equipped with elastic elements, each including a spring 216 respectively sleeved on the outer wall of one of the telescopic rods 213. The top of each spring 216 is fixedly connected to a rectangular plate 214, and the bottom of each spring 216 is fixedly connected to a rectangular plate 212. Four springs 216 are arranged in a linear array within the hollow rectangular box 211.

[0033] The support rod 313 is provided with a limiting component, which includes an arc-shaped limiting block 314 fixedly connected to one end of the support rod 313. The arc-shaped limiting block 314 is adapted to the ratchet gear 311. The arc-shaped limiting block 314 is triangular in shape.

[0034] By setting the limiting part 3, the threaded rod 222 can be effectively prevented from rotating on its own when it is not needed, ensuring the stability of the contact force between the cleaning plate 215 and the belt 113 after adjustment, and avoiding the cleaning effect from being affected by accidental reversal.

[0035] One specific application of this embodiment is as follows: When in use, the four-roller belt scale 112 is started, causing the belt 113 to rotate, thereby weighing and transporting the items to be weighed. During this process, the cleaning plate 215 contacts the outer wall of the belt 113, cleaning the outer wall of the belt 113. When hard objects adhere to the belt 113, impurities on the surface of the belt 113 are cleaned. Under the action of several telescopic rods 213 and springs 216... This ensures that the cleaning plate 215 and the surface of the belt 113 are in elastic contact. By rotating the threaded rod 222 through the handle 223, the threaded rod 222 causes the rectangular plate 212 to move upwards on the hollow rectangular box 211. At this time, the rectangular plate 212 compresses and deforms several telescopic rods 213 and several springs 216, generating elastic force. Through the reverse operation process, the elastic force of several springs 216 is reduced. Therefore, by adjusting the elastic force of several springs 216, adjustment is achieved. The force of the cleaning plate 215 contacting the surface of the belt 113, when the threaded rod 222 is rotated, causes the threaded rod 222 to drive the ratchet 311 to rotate. At this time, the ratchet 311 presses against the arc-shaped limiting block 314 through the arc surface of the arc-shaped limiting block 314, causing the arc-shaped limiting block 314 to press against the support rod 313 to slide on the hollow rectangular block 312, and causing the arc-shaped limiting block 314 to move away from the ratchet 311. During this process, the support rod 313 drives the circular plate 321 to press against the spring 322, promoting... The spring 322 deforms and generates elastic force. Under the action of the elastic force of the spring 322, the arc-shaped limiting block 314 is forced to engage with the ratchet 311 again, thereby rotating the threaded rod 222 repeatedly. Through the action of the right angle surface of the arc-shaped limiting block 314 and the right angle surface of the ratchet 311, the reverse rotation of the threaded rod 222 is restricted. When it is necessary to rotate the threaded rod 222 freely, the support rod 313 is pulled to move the arc-shaped limiting block 314 away from the ratchet 311, thereby rotating the threaded rod 222.
