Technical Field

[0001] This utility model relates to the technical field of belt scales, and in particular to a belt scale with a cleaning effect. Background Technology

[0002] In industrial production, belt scales are core metering devices for the continuous conveying of bulk materials, and their weighing accuracy directly affects the accuracy of production process control, trade settlement, and cost accounting. In actual operation, materials adhering to the conveyor belt surface (especially powdery or muddy materials with high moisture content and viscosity) have become one of the key factors leading to metering errors.

[0003] Currently, in order to improve the weighing accuracy of belt scales, scrapers are usually installed on the return section of the belt to remove adhering materials. However, the scraped-off materials are easy to re-adhere to the scraper blade or back, forming a stubborn accumulation layer, reducing the adhesion between the scraper and the belt, and weakening the cleaning efficiency. Utility Model Content

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The following description, in conjunction with the accompanying drawings, describes a belt scale with a cleaning effect according to an embodiment of the present invention.

[0021] like Figures 1 to 4 As shown, the belt scale with cleaning effect according to this utility model embodiment includes a conveyor belt 1, multiple support components 2, a first scraping component 3, a second scraping component 4, and a roller brush component 5.

[0022] The conveyor belt 1 is positioned between two support plates 6 via rollers, and multiple support components 2 are respectively positioned below the return section of the conveyor belt 1 and are in contact with the conveyor belt 1.

[0023] In an embodiment of the utility model, the support component 2 can support the carrying section of the conveyor belt 1 and is connected to the support plate 6 through a bracket. The support component 2 includes a bracket and a support roller. The support roller is rotatably mounted on the bracket and is in contact with the lower surface of the carrying section.

[0024] Furthermore, one of the rollers is connected to an external motor, which drives the roller to rotate, thereby moving the conveyor belt 1.

[0025] The return section of conveyor belt 1 is equipped with a speed measuring roller and a weighing mechanism, which are respectively connected to the controller.

[0026] It should be noted that the controller is mounted on the support plate 6, and the support plate 6 is also equipped with a display screen. The speed measuring roller can measure the speed of the conveyor belt 1 and transmit the test data to the controller. The weighing mechanism can dynamically weigh the material on the conveyor belt 1 and transmit the weight data to the controller. The controller analyzes and calculates the received speed and weight data and displays the calculated weight on the display screen. It is understood that the calculation principle of the belt scale is conventional technology in this field, and will not be described in detail in this utility model.

[0027] The first scraping component 3 is inclined between the two support plates 6, and the first scraping component 3 is positioned near the roller at the output end; the second scraping component 4 is reciprocally positioned on the scraping surface of the first scraping component 3, and the second scraping component 4 is connected to the drive mechanism 7.

[0028] It should be noted that the first scraping component 3 can scrape the small surface of the return section of the conveyor belt 1 to remove the material adhering to the conveyor belt 1, and the second scraping component 4 can clean the material on the first scraping component 3 to ensure that there is no material residue on the conveyor belt 1, thereby improving the accuracy of the belt scale.

[0029] The roller brush assembly 5 is rotatably positioned below the return section of the conveyor belt 1, and the roller brush assembly 5 is connected to the drive mechanism 7 through a transmission assembly.

[0030] In the embodiments of this utility model, the roller brush assembly 5 can further clean the conveyor belt 1, improving the cleanliness of the surface of the conveyor belt 1.

[0031] In one embodiment of this utility model, such as Figure 1 As shown, the first scraping assembly 3 includes a fixing plate 31, a first spring 32, and a first scraper 33. The fixing plate 31 is disposed between two support plates 6, and one end of the fixing plate 31 is provided with a groove. The first spring 32 is disposed in the groove. One end of the first scraper 33 is connected to the first spring 32, and the other end of the first scraper 33 abuts against the conveyor belt 1.

[0032] In the embodiments of this utility model, the first scraper 33 is inclined and one end of the first scraper 33 abuts against the conveyor belt 1 on the outer wall of the roller. The inclined first scraper 33 can remove the material remaining on the surface of the conveyor belt 1 in a timely manner.

[0033] Furthermore, such as Figure 1As shown, the second scraping assembly 4 includes a second scraper 41, two sliding plates 42, a connecting plate 43, and a second spring 44. The two supporting plates 6 have grooves 60 on their opposite sides, and the two sliding plates 42 are slidably connected to the corresponding grooves 60. The second spring 44 is disposed at the bottom end of the sliding plate 42 and is connected to the inner wall of the groove 60. The two ends of the connecting plate 43 are connected to the sliding plates 42. One end of the second scraper 41 is connected to the connecting plate 43, and the other end of the second scraper 41 abuts against the first scraper 33.

[0034] It should be noted that the second scraper 41 is inclined and the chute 60 is parallel to the second scraper 41. One end of the second scraper 41 abuts against the upper surface of the first scraper 33. The material scraped off the conveyor belt 1 slides off the upper surface. The reciprocating second scraper 41 can remove the material attached to the first scraper 33 in time, thereby improving the scraping effect of the first scraper 33.

[0035] Furthermore, a collection trough (not shown in the figure) may be provided below the first scraper 33 and the second scraper 41, and the cleaned material falls directly into the collection trough.

[0036] In one embodiment of this utility model, such as Figure 4 As shown, the drive mechanism 7 includes a motor 71, a rotating shaft 72, an incomplete gear 73 with a meshing relationship, and a toothed plate 74. The motor 71 is mounted on the side wall of one of the support plates 6; the rotating shaft 72 is connected to the output end of the motor 71, and one end of the rotating shaft 72 is located below the conveyor belt 1; the incomplete gear 73 is disposed on the rotating shaft 72; and the toothed plate 74 is disposed on the side wall of the slide plate 42.

[0037] It should be noted that the toothed plate 74 is arranged parallel to the second scraper 41. The toothed plate 74 is driven to move along the direction of the slide groove 60 by the drive mechanism 7, and the second scraper 41 is driven to reset by the second spring 44. This process is repeated to drive the second scraper 41 to move back and forth, thereby continuously removing the material on the first scraper 33 without leaving any material on the second scraper 41.

[0038] Specifically, see Figure 3 When the motor 71 starts, it drives the rotating shaft 72 to rotate. Through the engagement between the incomplete gear 73 and the toothed plate 74, the sliding plate 42, the connecting plate 43, and the second scraper 41 move upward. The second spring 44 is stretched, and the second scraper 41 scrapes off the material on the surface of the first scraper 33. When the incomplete gear 73 no longer meshes with the toothed plate 74, under the action of the second spring 44, the sliding plate 42, the second scraper 41, and the toothed plate 74 all move downward. This process repeats, thus driving the second scraper 41 to move back and forth.

[0039] In one embodiment of this utility model, such as Figure 1As shown, the roller brush assembly 5 includes a support shaft 51 and a brush roller 52. The support shaft 51 is rotatably disposed below the conveyor belt 1, and the support shaft 51 is connected to the rotating shaft 72 via a belt and a pulley. The brush roller 52 is disposed on the support shaft 51 and is in contact with the lower surface of the return end of the conveyor belt 1.

[0040] In the embodiments of this utility model, when the rotating shaft 72 rotates, it drives the support shaft 51 and the brush roller 52 to rotate in cooperation with the belt and pulley. The brush roller 52 is used to further clean the surface of the conveyor belt 1, thereby improving the cleaning effect of the conveyor belt 1.

[0041] Specifically, personnel place materials onto the carrying section of conveyor belt 1, which then transports the materials. Support components 2 support the carrying section to ensure stable material transport. Simultaneously, a weighing mechanism dynamically weighs the materials on conveyor belt 1, speed-measuring rollers detect the speed of conveyor belt 1, and a controller analyzes and calculates the acquired dynamic weight and speed data to determine the material's weight, which is then displayed on a screen.

[0042] Furthermore, during the conveying process of the conveyor belt 1, the first scraper 33 promptly scrapes away any residual material on the conveyor belt 1 to prevent the material from adhering to the conveyor belt 1. Some material slides down along the inclined surfaces of the first scraper 33 and the second scraper 41, while some material may adhere to the first scraper 33. At this time, the drive mechanism 7 drives the second scraper 41 to move back and forth to scrape away the material adhering to the first scraper 33. The material scraped off by the first scraper 33 will slide down along the second scraper 41, preventing the material adhering to the first scraper 33 from re-adhering to the conveyor belt 1, thus improving the cleaning effect of the conveyor belt 1.

[0043] In summary, the belt scale with cleaning effect of this utility model has a second scraper that reciprocates, which can promptly remove the material attached to the first scraper and prevent it from sticking back to the conveyor belt, thereby improving the surface cleaning effect of the conveyor belt and increasing the weighing accuracy of the belt scale.
