Technical Field

[0001] The utility model relates to the technical field of weighing and feeding equipment, in particular to an anti-blocking feeding device for a weighing machine. Background Art

[0002] A weighing machine is a device used to measure and weigh dry materials. It is widely used in manufacturing, warehousing, and logistics, helping companies improve production efficiency and product quality. Accurately measuring dry materials is crucial in many applications, including various production processes across a wide range of industries. When materials are continuously metered into a production process, their feed rate must be precisely controlled to ensure that the process operates as designed, the product composition is correct, and the quality of the finished product is not compromised. Various weighing feeders are used to weigh and supply dry materials such as sand, pebbles, grains, food, chemicals, pharmaceuticals, and ceramics. Dry materials require a loading mechanism to transport them before being weighed.

[0003] The feeding mechanism of the existing technology usually uses an auger for conveying, and transports the dry material in the hopper to the weighing machine. However, the dry material in the hopper may not be able to fall due to the tension, which leads to feeding faults. The staff needs to knock on the storage hopper from time to time, which reduces the feeding efficiency of the calcium powder. Therefore, we need to propose an anti-blocking feeding device for the weighing machine. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-blocking feeding device for a weighing machine, which is convenient for stirring the dry material during feeding, so that the dry material can be continuously transported to the weighing machine by the auger, thereby improving the transportation efficiency of the dry material, preventing the dry material from being broken and avoiding the dry material from clumping and clogging the material port, improving the weighing efficiency of the dry material, and solving the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: an anti-blocking feeding device for a weighing machine, comprising a bracket, a storage hopper is fixedly connected to the bracket, a driving anti-blocking mechanism for preventing dry material from being blocked is provided at the lower end of the storage hopper, a connecting pipe is provided at the discharge end of the storage hopper, a feeding mechanism is provided at one end of the connecting pipe, and a universal joint driven by the driving anti-blocking mechanism is provided at one end of the feeding mechanism;

The output shaft of the motor is transmission-connected to the rotating shaft. One end of the rotating shaft is fixedly connected to the first synchronous wheel. A synchronous belt is provided between the first synchronous wheel and the second synchronous wheel. The vertical shaft is located on the outside of one end of the storage hopper and is provided with multi-layer breaking rods. The bottom of the storage hopper is fixedly connected to a stabilizing cylinder for the vertical shaft to rotate.

[0007] Preferably, the multiple layers of breaking up rods are arranged at equal intervals, the lengths of the multiple layers of breaking up rods increase from bottom to top, and a plurality of the breaking up rods are provided in each layer.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model mainly realizes the coordination among the storage hopper, the driving breaking-up mechanism, the universal joint and the feeding mechanism, and provides kinetic energy through the motor. Under the transmission action of the first synchronous wheel, the second synchronous wheel and the synchronous belt, the vertical shaft can drive the breaking-up rod to make circular motion, thereby conveniently driving the breaking-up rod to stir and break up the dry material at the bottom of the storage hopper, avoiding the dry material agglomeration at the bottom of the storage hopper to block the transportation of the dry material, thereby improving the weighing efficiency of the weighing machine.

[0022] The multiple layers of breaking rods 36 are arranged at equal intervals, and the lengths of the multiple layers of breaking rods 36 increase from bottom to top. There are multiple breaking rods 36 on each layer.
