Description

Technical Field

[0001] The present application relates to the technical field of material discharge, and in particular to a material discharger for bulk materials with an adjustable discharge port diameter. Background Art

[0002] The existing funnel-shaped feeder is a conical structure with a large feed port and a small discharge port. The discharge port has a small diameter and cannot be adjusted, resulting in a slow feeding speed and being unable to adapt to packaging bags of different sizes connected to the discharge port. Therefore, it is inconvenient to use. There is also a feeder with an adjustable discharge port. Although the diameter of the discharge port will expand during feeding, the material only relies on gravity to slide down. For some special sticky materials, the feeding speed is still too slow, resulting in low production efficiency. At the same time, the side wall of the feed hopper is spliced ​​with sheet materials. When large pieces of material slide down, they will rub against the inner wall of the feed hopper, which makes the feeding speed slow and affects production efficiency. Utility Model Content

[0003] The purpose of the present application is to provide a feeder for bulk materials with an adjustable discharge port diameter, so as to solve the problem that the existing feeder has a slow discharge speed for bulk materials.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a feeder for bulk materials with an adjustable discharge port diameter, comprising a feed hopper and an external power assembly for driving a feed piston to open and close the feed hopper, the feed hopper comprising a feed port ring and a connecting handle connected to the feed port ring, a plurality of evenly spaced connecting strips are fixedly connected along a circumference of the feed port ring below the feed port ring, the ends of the plurality of connecting strips away from the feed port ring are inclined toward the center of the feed port ring to form a discharge port of the feed hopper, the feed piston enters the feed hopper downward to stretch the plurality of connecting strips to increase the diameter of the discharge port of the feed hopper, and after the feed piston moves upward and separates from the feed hopper, the plurality of connecting strips are reset to reduce the diameter of the discharge port.

[0005] The discharger used for bulk materials with an adjustable discharge port diameter drives the discharge piston up and down by means of an external power assembly at a fixed time. The discharge piston enters the discharge hopper to expand a plurality of connecting strips so that the diameter of the discharge hopper increases. After the discharge piston leaves the discharge, the connecting strip is reset so that the diameter of the discharge port decreases. Therefore, before the packaging bag reaches the discharge port, the diameter of the discharge port is the smallest. After the packaging bag reaches the discharge port, the discharge piston enters the discharge hopper so that a plurality of connecting strips are squeezed and expanded outward, thereby increasing the diameter of the discharge port. At the same time, the discharge port expands the bag mouth of the packaging bag to facilitate discharge. In addition, the discharger reduces the friction between the material and the discharge hopper, and bulk materials will not fall from the gaps in the connecting strips, thereby realizing rapid discharge of bulk materials.

[0006] Preferably, the connecting strip is made of stainless steel, which ensures the strength of the lower hopper and prevents it from deforming.

[0007] Preferably, the connecting strip is a cylindrical structure, and the outer surface of the connecting strip is smoothly arranged, which can reduce the friction force when feeding.

[0008] Preferably, the diameter of the connecting strip is 2-3 mm, and the spacing between adjacent connecting strips is 1-3 mm, so as to ensure the strength of the lower hopper and prevent the material from scattering after the connecting strips are stretched open.

[0009] Preferably, the connecting strip is welded to the feed port ring, and if a single connecting strip falls off, only one strip needs to be re-welded, which is convenient for maintenance compared to a sheet funnel.

[0010] Preferably, the discharge piston is a solid structure.

[0011] Preferably, the discharge piston is a truncated cone structure, the size of the upper surface of the discharge piston is larger than the upper surface, the upper surface of the discharge piston is externally connected to a power component, the size of the upper surface of the discharge piston is larger than the minimum diameter of the discharge port, and the size of the upper surface of the discharge piston is smaller than the diameter of the feed port.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows: the present discharger for bulk materials with adjustable discharge port diameter drives the discharge piston up and down in a timely manner through an external power component, and the discharge piston enters the discharge hopper to expand several connecting strips to increase the diameter of the discharge hopper. After the discharge piston leaves the discharge, the connecting strip is reset to reduce the diameter of the discharge port. Therefore, before the packaging bag reaches the discharge port, the diameter of the discharge port is the smallest. After the packaging bag reaches the discharge port, the discharge piston enters the discharge hopper to expand several connecting strips after being squeezed, thereby increasing the diameter of the discharge port. At the same time, the discharge port expands the bag mouth of the packaging bag to facilitate discharge. In addition, the present discharger reduces the friction between the material and the discharge hopper, and bulk materials will not fall through the gaps in the connecting strips, thereby achieving rapid discharge of bulk materials.
