Description

Technical Field

[0001] This utility model relates to the field of ink feeding technology, and in particular to an ink feeding structure with dustproof function. Background Technology

[0002] Currently, ink is an important material used in printing, which displays patterns and text on a substrate through printing or inkjet printing. Ink mainly consists of binders, pigments, fillers, additives, and solvents, and is widely used in various printing applications such as books, packaging, architectural decoration, and electronic circuit boards.

[0003] During the ink production process, when adding ink, the powdered material is usually poured directly into the collection and dispensing hopper. During the pouring process, the powder will spread, affecting the production environment and the health of workers. Furthermore, the powder spreading indoors may cause dust explosions, which is quite dangerous. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an ink feeding structure with dustproof function.

[0005] This utility model proposes an ink feeding structure with dustproof function, including a material hopper; a fan is installed on the top of the material hopper, a duct is connected to the fan, and a suction pipe is installed at the other end of the duct; it also includes a guiding cone and a tubular cloth belt; a discharge hopper is installed at the bottom of the material hopper, and an outlet pipe is installed at the bottom of the discharge hopper.

[0006] The guide cone is installed inside the hopper with its tip facing upwards. The axis of the guide cone coincides with the axis of the hopper and the axis of the outlet pipe. The outer wall of the guide cone is connected to the inner wall of the hopper by a connector. There are gaps between the outer wall of the guide cone and the inner wall of the hopper and the inner wall of the outlet pipe.

[0007] The bottom of the guide cone is equipped with a telescopic column, one end of the tubular fabric is installed on the outer wall of the outlet pipe, and the telescopic column is located inside the tubular fabric.

[0008] Preferably, the telescopic column includes a connecting cylinder and an ejector column. One end of the connecting cylinder is fixedly connected to the bottom of the guide cone, and the inner wall of its other end is slidably connected to the outer wall of one end of the ejector column.

[0009] Preferably, the telescopic column further includes an extension cylinder located between the connecting cylinder and the ejector column, with the outer wall of one end slidably connected to the inner wall of the connecting cylinder and the inner wall of the other end slidably connected to the outer wall of the ejector column.

[0010] Preferably, the extension cylinder can be provided in multiple sets with the diameter decreasing sequentially. In two adjacent sets of extension cylinders, the inner wall of the extension cylinder with the larger diameter is slidably connected to the outer wall of the extension cylinder with the smaller diameter, the outer wall of the extension cylinder with the largest diameter is slidably connected to the inner wall of the connecting cylinder, and the inner wall of the extension cylinder with the smallest diameter is slidably connected to the outer wall of the ejector column.

[0011] Preferably, the length of the tubular fabric strip is greater than the length of the telescopic column when it is stretched to its maximum.

[0012] Preferably, the outer wall of the outlet tube is equipped with several positioning rings, and one end of the tubular fabric tape connected to the outlet tube is provided with multiple sets of hooks, and the tubular fabric tape is positioned one by one with the positioning rings through the hooks.

[0013] Preferably, the outer wall of the outlet tube is provided with a circular groove, the circular groove is located below the positioning ring, and one end of the tubular cloth tape connected to the outlet tube is provided with an elastic band, the elastic band being engaged with the circular groove.

[0014] Preferably, the connectors are provided in at least three sets, distributed around the center of the guide cone's axis.

[0015] Preferably, the diameter of the outlet tube gradually increases from top to bottom.

[0016] This invention proposes a dustproof ink feeding structure. A fan draws powder into a hopper via a suction pipe on a guide tube, from which the powder falls into a discharge hopper. The discharge hopper has a top-to-bottom narrow structure and an internal guide cone. The gap between the guide cone and the discharge hopper gradually decreases, causing the powder to accumulate in the hopper and slowly discharge through the gap, thus slowing the discharge speed. The discharge cone is located at the center of the discharge hopper, dispersing the powder as it passes through, allowing it to flow downwards through an annular discharge port, achieving a dispersed discharge effect. A telescopic column at the bottom of the guide cone extends to the bottom of the feeding area, and a tubular cloth belt is provided on its exterior. This allows the powder to flow downwards along the telescopic column, acting as a guide and increasing frictional resistance during discharge, further slowing the discharge speed. The tubular cloth belt also prevents powder from splashing and spreading during discharge, achieving an environmentally friendly processing effect.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] like Figures 1-4 The ink feeding structure shown includes a material hopper 1; a fan 101 is installed on the top of the material hopper 1, a duct 7 is connected to the fan 101, and a suction pipe 701 is installed at the other end of the duct. It also includes a guide cone 4 and a tubular cloth belt 6. A discharge hopper 2 is installed at the bottom of the material hopper 1, and an outlet pipe 3 is installed at the bottom of the discharge hopper 2.

[0025] The guide cone 4 is installed inside the hopper 2 with its tip facing upward. The axis of the guide cone 4 coincides with the axis of the hopper 2 and the axis of the outlet pipe 3. The outer wall of the guide cone 4 is connected to the inner wall of the hopper 2 by a connector 401. There are gaps between the outer wall of the guide cone 4 and the inner wall of the hopper 2 and the inner wall of the outlet pipe 3.

[0026] The bottom of the guide cone 4 is equipped with a telescopic column 5, one end of the tubular fabric 6 is installed on the outer wall of the outlet pipe 3, and the telescopic column 5 is located inside the tubular fabric 6.

[0027] The blower 101 draws powder into the hopper 1 through the suction pipe 701 on the duct 7, and the powder falls into the discharge hopper 2. Since the discharge hopper 2 has a structure with smaller upper and lower sections, and a guide cone 4 is installed inside, the gap between the guide cone 4 and the discharge hopper 2 gradually decreases. Therefore, the powder in the hopper 1 will accumulate and slowly discharge through the gap, thus reducing the discharge speed. The discharge cone is located in the center of the discharge hopper 2, and the powder can be dispersed after passing through the discharge cone and discharged downward through the annular discharge port, which has the effect of dispersing the powder. The telescopic column 5 at the bottom of the guide cone 4 extends to the bottom of the feeding point. A tubular cloth belt 6 is provided on its outside, which allows the powder to be discharged downward along the telescopic column 5 during the discharge process, which plays a guiding role. It can increase the frictional resistance during the discharge process and slow down the discharge speed. The tubular cloth belt 6 prevents the powder from splashing and spreading during the discharge, which has the effect of environmentally friendly processing.

[0028] Preferably, the telescopic column 5 includes a connecting cylinder 501 and an ejector column 503. One end of the connecting cylinder 501 is fixedly connected to the bottom of the guide cone 4, and the inner wall of its other end is slidably connected to the outer wall of one end of the ejector column 503.

[0029] Preferably, the telescopic column 5 further includes an extension cylinder 502, which is located between the connecting cylinder 501 and the ejector column 503. The outer wall of one end of the extension cylinder 502 is slidably connected to the inner wall of the connecting cylinder 501, and the inner wall of the other end of the extension cylinder 502 is slidably connected to the outer wall of the ejector column 503.

[0030] Preferably, the extension cylinder 502 can be provided in multiple sets with the diameter decreasing sequentially. In two adjacent sets of extension cylinders 502, the inner wall of the extension cylinder 502 with the larger diameter is slidably connected to the outer wall of the extension cylinder 502 with the smaller diameter, the outer wall of the extension cylinder 502 with the largest diameter is slidably connected to the inner wall of the connecting cylinder 501, and the inner wall of the extension cylinder 502 with the smallest diameter is slidably connected to the outer wall of the ejector column 503.

[0031] The telescopic column 5 can change its length according to actual needs. The bottom end of the ejector column 503 of the telescopic column 5 is close to the bottom of the container to be fed, which can play the role of guiding the material. During the feeding process, it increases the frictional resistance of the powder, slows down the feeding speed, avoids dust diffusion, and plays a dust prevention role.

[0032] Preferably, the length of the tubular fabric belt 6 is greater than the length of the telescopic column 5 after it is stretched to its maximum length, so that it can always wrap the powder during the powder feeding process.

[0033] Preferably, the outer wall of the outlet tube 3 is equipped with several positioning rings 302, and one end of the tubular cloth strip 6 connected to the outlet tube 3 is provided with multiple sets of hooks. The tubular cloth strip 6 is positioned one by one with the positioning rings 302 through the hooks, which facilitates the detachable installation of the tubular cloth strip 6 and the outlet tube 3.

[0034] Preferably, the outer wall of the outlet tube 3 is provided with a circular groove 301, which is located below the positioning ring 302. One end of the tubular cloth strip 6 connected to the outlet tube 3 is provided with an elastic band 601. The elastic band 601 is engaged in the circular groove 301, which can achieve a sealing effect between the tubular cloth strip 6 and the outlet tube, and can also adaptively adjust the length of the tubular cloth strip 6 according to the length of the telescopic column 5.

[0035] Preferably, the connector 401 is provided in at least three sets, distributed around the center of the guide cone 4, to enhance the firmness of the guide cone 4.

[0036] Preferably, the diameter of the outlet tube 3 gradually increases from top to bottom, which can match the shape of the guide cone 4 and maintain the uniformity of the gap between the outlet tube and the guide cone 4.
