Problems solved by technology
[0003] However, most of the existing quantitative feeders are transported through the conveyor belt, and all the materials are accumulated on the conveyor belt and continuously transported to the target point. Uniformity will easily lead to a decline in the production quality of the product, which is not conducive to the promotion and sales of the product; and once the quantitative mechanism valve of the existing quantitative feeder cannot be closed in time, the weight of the material will be overweight, and the change in the weight of the material delivered quantitatively will lead to material ratio Changes may easily cause product production accidents and cause huge economic losses

Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] see Figure 1-4 , the limited supply device of the metering feeder, including a screening device 1 and a feeding device 2, the upper end of the feeding device 2 is provided with a screening device 1, and the screening device 1 includes a screening cylinder 11, an observation window 12, a feed hopper 13. Feeding pipe 14, electric control valve 15 and spiral pipe 16. There is an observation window 12 on one side of the outer wall of the screening cylinder...

The invention discloses a limited supply device for a metering feeder. A spiral tube with a screen net at the bottom is arranged inside the screening cylinder, and a slanting plate is arranged between the inner walls of the screening cylinder, and the sloping plate is penetrated by the lower end of the spiral tube. And the lower end of the slope is connected to the discharge port on the side wall of the screening cylinder. The material coming down from the feeding hopper rotates and slides down the spiral tube under the action of gravity, and the fine particle powder mixed in the material leaks from the screening net when sliding Next, after being collected by the slant plate, it is discharged from the discharge port to remove the fine powder mixed in the material, so as to prevent the fine powder from affecting the production quality of the product. A limited material receiving mechanism is installed on the bottom plate of the second chamber. With the cooperation of the receiving plate, U-shaped frame and connecting rod, the plugging end is installed at the top port of the connecting pipe. When the spring group is used to maintain the normal relaxation state and the compressed state after receiving the material, the blocking end moves up and down to the top port of the connecting pipe. Blocking and dredging are carried out to realize the limited supply of materials inside the transfer drum, which is convenient and practical.
Description
technical field [0001] The invention relates to the technical field of blanking equipment, in particular to a limited supply device of a metering feeder. Background technique [0002] Quantitative feeder is a mechanical equipment that continuously weighs, measures and delivers quantitatively for solid bulk materials (blocks, granules, powders, etc.). It is widely used in cement, mining, building materials, grain, chemical and other industries. Known for its advanced technology, stability and reliability, high cost performance and durability, it is a high-tech product integrating conveying, weighing measurement and quantitative control. [0003] However, most of the existing quantitative feeders are transported through the conveyor belt, and all the materials are accumulated on the conveyor belt and continuously transported to the target point. Uniformity will easily lead to a decline in the production quality of the product, which is not conducive to the promotion and sales...
