Description

Technical Field

[0001] The utility model belongs to the technical field of electronic weighing equipment, in particular to an electronic belt scale. Background Art

[0002] The weighing roller of the belt scale is a key component for guiding the belt, and the weighing sensor installed under the roller is used to instantly measure the material passing through the roller. It is the most critical part of the belt scale. The belt scale refers to an automatic scale that continuously weighs bulk materials on the conveyor belt without subdividing the mass or interrupting the movement of the conveyor belt.

[0003] The weighing rollers of existing belt scales are usually fixedly installed on the main frame of the belt scale through a fixed shaft running through the inside thereof, and are driven by the transmission belt. Since the weighing rollers need to withstand the pressure generated by the mass of the transmitted materials, they are used for a long time. Due to some dust, impurities and materials on the belt, the rollers may get stuck. As a result, the rollers do not follow the belt transmission when the belt is driven, which seriously affects the weighing accuracy and easily causes damage to the belt or rollers. During the working process, it is difficult for the staff to detect and judge which roller is stuck, making it inconvenient to replace the rollers. Utility Model Content

The following is a description of the embodiments of the present invention based on its overall structure. Example

[0030] See also Figure 1-5 An electronic belt scale comprises a weighing frame 1, on which brackets 2 are arranged at intervals, on which horizontal rollers 3 are arranged, and on which side rollers 4 are arranged at both ends of the horizontal rollers 3. The angle formed between the horizontal rollers 3 and each side roller 4 is an obtuse angle, and on each horizontal roller 3 and side roller 4, a wireless pressure sensor 5 is arranged, and the wireless pressure sensor 5 is embedded in the surface of the rollers and side rollers 4. The rollers and measuring rollers roll with the belt transmission, and a unique ID is arranged inside each wireless pressure sensor 5, and each horizontal roller 3 or side roller 4 is marked with a different serial number, and wireless pressure sensors 5 with different IDs match different serial numbers;

[0031] A weighing sensor 6, the weighing sensor 6 is arranged on the weighing frame 1;

[0032] The speed sensor 7 is arranged at the bottom of the weighing frame 1 and abuts against the belt at the bottom to measure the speed;

[0033] The weighing display controller 8 is arranged on one side of the belt and is connected to the weighing sensor 6, the speed sensor 7 and the wireless pressure sensor 5 respectively.

[0034] The working principle of the above scheme is as follows: during installation, the weighing frame 1 is fixed on the conveyor frame 9, and brackets 2 are arranged at intervals on the weighing frame 1. The number of brackets 2 can be set as needed. When the belt carries materials for transmission, the horizontal rollers 3 on the brackets 2 and the side rollers 4 on both sides play a role of lifting the belt, and the materials on the belt will be tightly attached to the horizontal rollers 3 and the side rollers 4 on both sides, exerting pressure on the horizontal rollers 3 and the side rollers 4 on both sides. The wireless pressure sensor 5 rotates with the rotation of the horizontal rollers 3 and the side rollers 4. During the belt transmission process, the horizontal rollers 3 and the side rollers 4 rotate accordingly. When the wireless pressure sensor 5 is located below the belt, it will be subjected to the pressure of the material. When the wireless pressure sensor 5 is not below the belt, it will not be subjected to pressure and there will be no pressure value. Therefore, the wireless pressure sensor 5 will be subjected to pressure periodically, and its pressure value will change periodically, and the value change and the corresponding wireless sensor ID will be displayed on the weighing display controller 8. The transmission speed value of the belt read by the speed sensor 7 and the material weight value read by the weight sensor are displayed; when the weighing display controller 8 does not display that the pressure on the wireless pressure sensor 5 shows a periodic change, it can be determined that the horizontal roller 3 or the measuring roller is in a stuck and non-rotating state, and then the wireless pressure sensor 5ID on the horizontal roller 3 or the side roller 4 is used to quickly lock the stuck horizontal roller 3 or the side roller 4, because when the wireless pressure sensor 5 is installed, the serial number of the horizontal roller 3 or the side roller 4 corresponding to each wireless pressure sensor 5ID will be recorded. Finally, after determining the stuck horizontal roller shaft or side shaft 15, the horizontal roller 3 or side roller 4 with the corresponding serial number is found and switched to ensure the normal operation of the electronic belt scale. In this embodiment, the wireless pressure sensor 5 adopts the MD-S151 ultra-small wireless Bluetooth pressure sensor of Mingkong Sensing, and other types of pressure sensors can be used in other embodiments.

When the side roller 4 gets stuck, it is convenient to take it out from the inclined bayonet 18 for replacement, and it is also more convenient to install. At the same time, after the side shaft 15 is installed, there is a part above the measuring shaft that limits the side shaft 15 to prevent the side shaft 15 from slipping, thereby improving the stability of the belt transmission. The inclination direction of the inclined bayonet 18 is opposite to the direction of belt movement, so that the direction of rotation of the side roller 4 is opposite to the direction of the inclined bayonet.

[0046] It can be understood that the first T-shaped block 20 can be clamped on the hanging mouth 12 to prevent the two ends of the fixed shaft 11 from slipping off the hanging mouth 12 when the horizontal roller 3 rotates. At the same time, the first T-shaped block 20 and the two ends of the fixed shaft 11 are detachably connected, such as threaded connection. When replacing the horizontal roller 3, the first T-shaped block 20 at one end is rotated out and the horizontal roller 3 can be taken out.
