A colorant metering device for powder coating

Abstract

This utility model relates to the field of metering technology for powder coating production, and discloses a colorant metering device for powder coating, including a metering hopper with a leveling mechanism. Colorant is injected into the metering hopper via a pusher hopper. When the metering hopper is full, the pusher hopper is further pushed, causing excess colorant to be pushed through a guide hopper into a surplus material box, ensuring the colorant precisely fills the space enclosed by the metering hopper, baffle, and limiting seat. The limiting seat is then pulled to discharge the colorant. Installing the device on powder coating processing machinery can save colorant metering and transfer time. By controlling the positioning bolts, the fixed seat moves on the metering hopper. By observing the scale value on the corresponding scale plate of the limiting seat, the maximum storage amount in the metering hopper above the limiting seat can be quickly controlled. Using a scale plate as a metering reference improves colorant metering efficiency.

Technical Field

[0001] This utility model relates to the field of metering technology for powder coating production, specifically to a colorant metering device for powder coating. Background Technology

[0002] A powder coating pigment metering device is a device used to measure the amount of pigment used. It includes a balance principle to achieve the mixing ratio. The device is usually equipped with a balance frame, pigment cup, water cup and screw feeding mechanism. The measurement of pigment cup and water cup ensures the scientific nature of pigment mixing.

[0003] Chinese patent provides a colorant metering device suitable for powder coatings, publication number CN222912867U. The base has an upward-opening slot at its front end. A pair of first supports are mounted on the base on both sides of the slot, each with a through hole. A rotating shaft corresponding to the through hole is located in the middle of a balancing frame. The balancing frame is movably mounted in the through hole of the first support via the rotating shaft and is situated within the slot. Placement cylinders are fixedly mounted at both ends of the balancing frame. A colorant cup is movably placed in the left placement cylinder, and a water cup is movably placed in the right placement cylinder. A storage box is fixedly mounted at the rear end of the base via a second support. A screw feeding mechanism is fixedly mounted at the lower end of the storage box. The advantages of this invention are: by setting up a balancing frame and utilizing the working principle of a balance, with colorant and water cups respectively positioned at both ends of the balancing frame, the colorant and water cups are precisely fed by the feeding mechanism, achieving accurate and scientific metering of the colorant.

[0004] The above-mentioned device has the function of measuring pigments using a balance frame. However, due to the compact size of the device and the large number of parts, an independent space is required when measuring pigments, which increases the complexity of the measurement process. Furthermore, the water cup used for measurement requires constant control of its internal water volume, resulting in low measurement efficiency. Therefore, it is necessary to provide a pigment measuring device for powder coatings. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This powder coating pigment metering device injects pigment into the metering hopper through a pusher hopper. When the metering hopper is full of pigment, the pusher hopper is pushed further to push the excess pigment into the surplus material box through the guide hopper.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 A powder coating pigment metering device includes a metering hopper 1, on which a leveling mechanism 2 is provided. The leveling mechanism 2 includes a baffle 201 and a pusher hopper 202. The baffle 201 is slidably installed on one side of the metering hopper 1, and the pusher hopper 202 is slidably installed on the upper part of the metering hopper 1. A fixed seat 203 is fixedly installed in the middle of the baffle 201. A limiting seat 204 is slidably installed through the baffle 201 and the fixed seat 203. Two supporting springs 205 are fixedly installed side by side between the limiting seat 204 and the fixed seat 203. A guide hopper 206 is fixedly installed on one side of the metering hopper 1, and a surplus material box 207 is slidably installed on the lower part of the guide hopper 206.

[0025] The length of the baffle 201 is twice the height of the measuring hopper 1, and both ends of the baffle 201 are fixedly equipped with protrusions to ensure that the limiting seat 204 of the baffle 201 can be pushed to the upper and lower sides of the measuring hopper 1 without detaching. The pusher hopper 202 consists of a horizontal plate and a square hopper, and the lower side of the square hopper is adapted to the measuring hopper 1. When the measuring hopper 1 is full of pigment, the excess pigment can be pushed into the surplus material box 207 by pushing the pusher hopper 202 to ensure that the upper part of the pigment in the measuring hopper 1 is level. The limiting seat 204 consists of a push rod and a square plate, and the square plate is adapted to the measuring hopper 1. In use, by pulling the limiting seat 204 to move it outward from the measuring hopper 1, the support force at the bottom of the pigment in the measuring hopper 1 can be removed, allowing the pigment to fall under the action of gravity.

[0026] Example 2

[0027] See Figure 5 A quantitative mechanism 3 is provided on the fixed base 203. The quantitative mechanism 3 includes a fixed plate 301 and a buckle 302. The fixed plate 301 is fixedly installed on the upper part of the measuring hopper 1. A positioning bolt 303 is threaded through the fixed plate 301. A buckle body 304 is fixedly installed at one end of the positioning bolt 303. Two scale plates 305 are fixedly installed side by side on one side of the measuring hopper 1.

[0028] The positioning bolt 303 is rotatably connected to the buckle seat 302 via the buckle body 304, and one end of the positioning bolt 303 is higher than the baffle 201. The scales on the two scale plates 305 are opposite to each other, and one scale corresponds to the volume 1 cm enclosed by the measuring hopper 1 and the baffle 201. 3， In use, the positioning bolt 303 supports the fixed seat 203 to move up and down, and the scale value on the scale plate 305 corresponding to the limit seat 204 is observed, thereby controlling the maximum storage capacity of the metering hopper 1 above the limit seat 204.

[0029] In actual operation, pigment is injected into metering hopper 1 through pusher hopper 202. When the pigment fills metering hopper 1, pusher hopper 202 is pushed further to push the excess pigment into surplus material box 207 through guide hopper 206. The pigment just fills the space formed by metering hopper 1, baffle 201 and limiting seat 204. Pulling limiting seat 204 further discharges the pigment. When in use, the device is installed on powder coating processing machinery, which can save pigment metering and transfer time.

[0030] By controlling the positioning bolt 303, the fixed seat 203 can move on the metering hopper 1. When in use, by observing the scale value on the scale plate 305 corresponding to the limit seat 204, the maximum storage amount in the metering hopper 1 above the limit seat 204 can be quickly controlled. By using the scale plate 305 as a reference, the efficiency of colorant metering can be improved.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
