Description

Technical Field

[0001] The utility model relates to the field of supply equipment, in particular to a raw material adding device. Background Art

[0002] At present, the method of adding powdered materials is basically to unpack the bags and directly discharge the materials (after the ton bags containing the materials are unpacked, the materials are introduced into the reactor through the material guide port).

[0003] See also Figure 1 and Figure 2 Among them, one of the existing bag-opening structures is that after the ton bag is cut by the staggered cutting blades, a long strip-shaped crack is formed on the surface of the bag. The bag cannot maintain the state of holding the material, and the material will fall out of the bag through the crack. Ideally, the cut crack needs to reach a predetermined length (the length of the crack determines the falling speed of the material). However, in some cases, the crack length cannot meet the requirement. For example, the material in the bag is unevenly distributed, resulting in insufficient support force on the bag surface (the support force of the bag surface is mainly supported by the internal material). The part of the bag with less material becomes flexible due to the insufficient support force, making it difficult to be cut by the cutting blade.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] See also Figure 3 and Figure 4The present invention provides a raw material adding device, which includes a material conveying platform 1, a cutting knife group 2 arranged at its end, and a bag material homogenization structure 3 arranged at the feed end of the cutting knife group 2; wherein the type of the material conveying platform 1 can be selected from a powered conveyor belt type conveyor (a conveyor belt is provided on the working surface of the material conveying platform 1) or an unpowered roller conveyor and a smooth surface conveyor (unpowered conveyor requires that the conveying platform has a certain inclination angle to ensure stable material delivery to the cutting knife group 2). In this embodiment, the material conveying platform 1 adopts a smooth surface conveyor with a certain inclination angle. The number of cutting knives in the cutting knife group 2 can be selected as needed, and the shape and structure of the cutting knives can also be selected as needed. For example, as shown in this embodiment, a disc cutting knife is used (which is driven to rotate during operation to achieve cutting work).

[0020] The bag material homogenization structure 3 includes a blocking member 4, which is a roller structure, at a predetermined distance from the material conveying platform 1 to form an extrusion channel. The bag 01 conveyed by the material conveying platform 1 passes through the extrusion channel, and any unevenly distributed material within the bag is blocked by the blocking member 4. For example, in the figure, the material in the bag is affected by gravity and the amount of material at the end is small. When the bag passes through the blocking member 4, the material is blocked to the end. At this time, the end of the bag is supported by the material, making the bag easier to cut with a knife.

[0021] Preferably, the distance between the blocking member 4 and the material conveying platform 1 of the present invention is adjustable, and the two are connected by an adjustment bracket 5 to adapt to the material content in the bag body and increase the versatility of the equipment. Adjustment brackets 5 are installed at both ends of the blocking member 4; the ends of the adjustment bracket 5 are hinged to the material conveying platform 1. The angle adjustment of the adjustment bracket 5 can be fixed. For example, as shown in the figure, a number of adjustment holes 7 are provided at the hinge (material conveying platform 1), and corresponding holes are provided on the adjustment bracket 5. The positioning member transmits the light into the two holes to realize the hinged positioning of the adjustment bracket 5. Alternatively, the adjustment bracket 5 is directly connected to the material conveying platform 1 through a tension spring, so that the blocking member 4 produces an adaptive extrusion effect (the extrusion force depends on the tension of the tension spring).

[0022] In addition, the blocking member 4 of the present invention can be rotatably or fixedly mounted on the adjustment bracket 5. In this example, in order to ensure that the bag can stably pass through the extrusion space when squeezed, the blocking member 4 can be rotatably mounted on the adjustment bracket 5, and the adjustment bracket 5 is equipped with a driver (a rotary motor can be used, not shown in the figure) that drives the blocking member 4 to rotate.

[0023] In summary, the present invention provides a raw material adding device, including a material conveying platform, a cutting knife group arranged at its end, and a bag material homogenization structure arranged at the feed end of the cutting knife group; wherein, the type of the material conveying platform can be selected as a powered conveyor belt type conveyor (a conveyor belt is arranged on the working surface of the material conveying platform) or an unpowered roller type conveyor and a smooth plane conveyor (unpowered conveying requires ensuring that the conveying platform has a certain inclination angle to ensure that the material is stably conveyed to the cutting knife group), and the material conveying platform adopts a smooth plane conveyor with a certain inclination angle. The number of cutting knives in the cutting knife group can be selected as needed, and the shape and structure of the cutting knife can also be selected as needed. For example, as shown in this embodiment, a disc cutting knife is adopted (driven to rotate during operation to achieve cutting work). The present invention evenly distributes the material inside the bag body by extrusion, ensures the support force of the bag body surface, and further ensures the cutting effect.

[0024] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
