Description

Technical Field

[0001] The present application relates to the technical field of material discharge, and in particular to a material discharger with an unpowered discharge port having an adjustable caliber. 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 downward. For some special sticky materials, the feeding speed is still too slow, resulting in low production efficiency. Utility Model Content

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

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a non-powered discharge port with adjustable diameter, comprising an openable and closable discharge hopper 1 and an external power assembly for driving a discharge piston to open and close the discharge hopper, the discharge hopper comprising two fan-shaped discharge hopper pieces, both of which are arc-shaped structures, and the two fan-shaped discharge hopper pieces are connected by elastic parts to form the discharge hopper, the discharge piston enters the discharge hopper downward to expand the elastic part between the two fan-shaped discharge hopper pieces to increase the diameter of the discharge port of the discharge hopper, and after the discharge piston moves upward and separates from the discharge hopper, the elastic part automatically rebounds to reduce the diameter of the discharge port.

[0005] The unpowered discharge port with adjustable diameter drives the discharge piston up and down by an external power component at a fixed time. The discharge piston enters the discharge hopper to expand the diameter of the discharge hopper. After the discharge piston leaves the discharge port, the elastic part automatically rebounds 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 the diameter of the discharge port. At the same time, the discharge port expands the bag mouth of the packaging bag to facilitate discharge.

[0006] Preferably, the unloading piston is a truncated cone structure, the size of the upper surface of the unloading piston is larger than the upper surface, the upper surface of the unloading piston is externally connected to a power component, the size of the upper surface of the unloading piston is larger than the minimum diameter of the discharge port, and the size of the upper surface of the unloading piston is smaller than the diameter of the feed port. This design can ensure that the size of the unloading piston can expand the diameter of the discharge port by expanding the elastic part.

[0007] Preferably, the unloading piston is detachably connected to the external power assembly, so that the unloading piston can be easily disassembled when it needs to be cleaned.

[0008] Preferably, the external power assembly includes a telescopic cylinder, the output shaft of which is connected to the upper surface of the discharge piston. The telescopic cylinder drives the discharge piston to move up and down so that the discharge port diameter is regularly expanded and contracted, thereby realizing rapid discharge of materials from the discharge hopper.

[0009] Preferably, the discharge piston is made of stainless steel, which has a certain hardness and is easy to clean.

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

[0011] Preferably, the elastic member is a spring, and the two ends of the spring are respectively connected to the two fan-shaped hopper pieces, and the two fan-shaped hopper pieces are driven to move away from or close to each other by the spring expansion and contraction, thereby adjusting the diameter of the discharge port.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows: the unpowered discharge port with adjustable 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 the diameter of the discharge hopper. After the discharge piston leaves the discharge port, the elastic part automatically rebounds 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 increase the diameter of the discharge port. At the same time, the discharge port expands the bag mouth of the packaging bag to facilitate discharge. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 As shown, the discharge hopper 1 is a conical structure, which cooperates with the discharge piston 2 of the truncated cone structure. The discharge piston 2 enters the discharge hopper 1 to stretch the elastic member, and the two fan-shaped discharge hopper pieces 11 move away from each other, so that the diameter of the discharge port 12 is expanded. The external power component includes a telescopic cylinder 3, and the output shaft of the telescopic cylinder 3 is detachably connected to the upper surface of the discharge piston 2. The discharge piston 2 is a solid structure made of stainless steel. The discharge piston 2 can be retracted and retracted at a fixed time under the drive of the telescopic cylinder 3. When the packaging bag reaches the discharge port 12, the discharge piston 2 moves downward into the discharge hopper 1 to open the spring between the two fan-shaped discharge hopper pieces 11, so that the diameter of the discharge port 12 of the discharge hopper 1 is increased until the bag mouth of the packaging bag is opened. After the discharge is completed, the discharge piston 2 moves upward and separates from the discharge hopper 1, and the elastic member automatically rebounds to reduce the diameter of the discharge port 12, completing a set of discharge, and continuing to discharge in a cycle.
