Description

Technical Field

[0001] This utility model relates to the field of funnel technology, and in particular to a quantitative funnel for adding water-based industrial coatings. Background Technology

[0002] Water-based industrial coatings, as a material suitable for wall decoration, can be applied to interior walls and offer advantages such as easy application, rapid drying, water resistance, and scrub resistance, making them widely used in the construction industry. Before using water-based artistic coatings, they need to be diluted with water as a dispersant, requiring a coating mixer. For convenient dispensing, a funnel is typically used. Chinese Patent Publication No. CN220684679U discloses a quantitative funnel for dispensing water-based industrial coatings, comprising a funnel body. The side of the funnel body is connected to a hinge seat, which is then bolted together. The inner wall of the funnel body is connected to a motor via a first connecting frame, and the motor shaft is connected to a second connecting frame, which in turn is connected to a first scraper. The metering funnel for feeding water-based industrial coatings features an intermittent discharge structure, achieving a precise metering effect and preventing clogging caused by excessive one-time discharge. The motor's forward and reverse rotation drives a rotating plate to move synchronously. When the notch on the rotating plate aligns with the sieve holes on the sieve plate, the coating flows sequentially from the sieve holes and notch into the threaded tube, sleeve, and storage device. A second scraper is included; when the motor operates, it contacts the inner wall of the threaded tube, scraping off coating adhering to the inner wall and allowing it to fall into the sleeve, preventing clogging. However, the patented motor is installed inside the funnel, directly contacting the water-based industrial coating. This poses a risk of short circuits and corrosion, and prolonged contact with the coating causes a coating to form on the motor casing, hindering effective heat dissipation. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a quantitative funnel for feeding water-based industrial coatings, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a quantitative funnel for adding water-based industrial coatings, comprising a funnel body, the bottom of which is connected to a plurality of connecting pipes arranged in a circular array, the bottom end of which is provided with a fixing plate, and the bottom of which is connected to a threaded pipe; a dual-shaft motor is fixed at the bottom center of the funnel body, one output end of which extends vertically upwards into the interior of the funnel body and is fixed with a horizontally arranged connecting rod, the end of which is fixed with a funnel scraper, and the top of which is connected to the connecting rod and the funnel scraper with an L-shaped fixing rod; the other output end of the dual-shaft motor extends vertically downwards through the fixing plate and is connected to a horizontally arranged sieve plate, the bottom edge of which is provided with a threaded pipe scraper.

[0005] Furthermore, a cavity is provided on the side wall of the connecting pipe, and a heating coil is provided inside the cavity.

[0006] Furthermore, the outer wall of the connecting pipe is covered with a heat insulation layer.

[0007] Furthermore, the inner wall of the connecting pipe is coated with an anti-stick coating.

[0008] Furthermore, a stirring rod is provided on the fixed rod.

[0009] Furthermore, the sieve plate is provided with a plurality of sieve holes arranged in a circular array. Beneficial effects

[0010] Compared with the prior art, the present invention has at least the following advantages:

[0011] 1. The funnel of this utility model places the motor on the outside, avoiding the risks of short circuits, corrosion and heat dissipation problems caused by placing the motor inside the funnel in the prior art.

[0012] 2. The funnel and the threaded pipe are connected by multiple connecting pipes. These connecting pipes are responsible for conveying the water-based industrial coating. A cavity is provided on the side wall of each connecting pipe, and a heating coil is installed inside the cavity to heat the connecting pipe. This ensures good flow of the water-based industrial coating at the connecting pipe, reducing coating retention and adhesion, and preventing blockage. The inner wall of the connecting pipe is coated with an anti-stick coating to further reduce coating adhesion.

[0013] 3. The motor of this utility model is a dual-shaft motor. One output end is connected to a funnel scraper via a connecting rod and a fixing rod to scrape off the coating on the side wall of the funnel. The other output end is connected to a sieve plate. When the sieve holes of the sieve plate coincide with the connecting pipe, the coating flows into the threaded pipe. A threaded pipe scraper is provided at the bottom edge of the sieve plate, which scrapes off the coating on the side wall of the threaded pipe when the sieve plate rotates.

[0021] See Figures 1-3 This embodiment provides a metering funnel for adding water-based industrial coatings, including a funnel body 1. The bottom of the funnel body 1 is connected to a plurality of connecting pipes 2 arranged in a circular array. The bottom of the funnel body 1 is provided with a plurality of funnel outlets 9 corresponding to the positions of the connecting pipes. The bottom end of the connecting pipes 2 is provided with a fixing plate 14. The fixing plate 14 is provided with a plurality of threaded pipe inlets 10 corresponding to the positions of the connecting pipes. The bottom of the fixing plate 14 is connected to a threaded pipe 3.

[0022] A dual-shaft motor 4 is fixed at the bottom center of the funnel body 1. One output end of the dual-shaft motor 4 extends vertically upwards into the interior of the funnel body 1 and is fixed with a horizontally arranged connecting rod 6. The bottom end of the funnel scraper 13 is fixed to the end of the connecting rod 6. An L-shaped fixing rod 7 connects the connecting rod 6 and the top of the funnel scraper 13. A stirring rod 8 is provided on the fixing rod. The other output end of the dual-shaft motor 4 extends vertically downwards through a fixing plate 14 and is connected to a horizontally arranged sieve plate 11. The sieve plate 11 has multiple sieve holes 110 arranged in a circular array. A threaded tube scraper 12 is provided at the bottom edge of the sieve plate 11 to scrape off the water-based industrial coating adhering to the threaded tube and prevent the threaded tube from becoming clogged.

[0023] Preferably, the sidewall of the connecting pipe 3 is provided with a cavity 20, and a heating coil 5 is provided inside the cavity 20 for heating the connecting pipe 3. This improves the flowability of the water-based industrial coating at the connecting pipe, reduces coating retention and adhesion to the connecting pipe 3, and prevents blockage. The outer wall of the connecting pipe 3 is covered with a heat insulation layer, and the inner wall of the connecting pipe 3 is coated with an anti-stick coating to further reduce coating adhesion to the connecting pipe 3. In this embodiment, the anti-stick coating is a polytetrafluoroethylene coating.

[0024] During operation, the paint falls into the funnel body 1. Due to the paint's adhesive properties, it easily adheres to the inner wall of the funnel body 1 during its descent. Upon activation, the dual-shaft motor 4 drives the funnel scraper 13 and the threaded tube scraper 12 to rotate in both directions, each rotation not exceeding one revolution. During rotation, the funnel scraper 13 scrapes the inner wall of the funnel body 1, removing the paint adhering to it. The threaded tube scraper 12 removes paint adhering to the inner wall of the threaded tube, preventing blockage. Because the motor's operation causes the sieve plate to move synchronously, when the sieve holes align with the bottom of the connecting pipe, the paint flows into the threaded tube.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
