Description

Technical Field

[0001] The utility model relates to the technical field of powder coating production, in particular to a resin powder weighing device for powder coating stirring production. Background Art

[0002] In recent years, due to the rise of the furniture industry, powder coatings have entered the furniture market with their bright colors, strong and durable characteristics, and are widely used in some steel furniture, outdoor leisure furniture, bookcases and archives, teaching aids and desks. It has very good decorative effects and appearance. The coating film does not turn yellow during curing and baking, has good physical properties, and has good weather resistance. With the complete supporting facilities of powder coating raw materials, production equipment, testing instruments, and spraying equipment, my country's powder coating industry has achieved unprecedented development, with great progress in variety, quantity, quality, application, and people's understanding.

[0003] Powder coatings require resin powder to be added to the coating for mixing and stirring. The addition ratio has precise requirements, so the resin powder added to the mixing tank needs to be accurately weighed. If the weighed powder is quickly added to the mixing tank, it is easy to cause uneven mixing and agglomeration. Therefore, the powder addition speed needs to be controlled. In addition, due to the high humidity inside the mixing tank, the powder is easy to compact on the inner wall of the hopper, resulting in some powder being unable to be added to the mixing tank. Utility Model Content

Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-5The resin powder weighing device for powder coating stirring production shown in the figure includes a stirring tank 1, a mounting base 2, a weighing sensor 3 and a feeding component 4, wherein the mounting base 2 is fixedly arranged on the inner side of the stirring tank 1, the weighing sensor 3 is installed on the inner side of the bottom of the mounting base 2, the feeding component 4 is arranged inside the stirring tank 1, the feeding component 4 includes a hopper 41, a clamping bar 42, a knocking component 43 and a control component 44, the clamping bar 42 is fixedly arranged on the outer side of the top of the hopper 41, the knocking component 43 is installed on the outer side of the hopper 41, the control component 44 is installed on the bottom of the hopper 41, the knocking component 43 includes a connecting seat 431, a first cylinder 432 , pull plate 433, adsorption magnet 434, sleeve 435, pull rod 436, knocking ball 437, spring 438 and control magnet 439, the connecting seat 431 and the sleeve 435 are fixedly arranged on the outer surface of the hopper 41, the first cylinder 432 is installed on the outside of the connecting seat 431, the pull plate 433 is fixedly arranged at the telescopic end of the first cylinder 432, the adsorption magnet 434 is clamped on the inner bottom of the pull plate 433, the pull rod 436 is clamped in the sleeve 435, the spring 438 is sleeved on the outside of the pull rod 436, the knocking ball 437 is fixedly arranged at one end of the pull rod 436, and the control magnet 439 is fixedly arranged at the other end of the pull rod 436.

[0024] Specifically, the control component 44 includes a mounting frame 441, a second cylinder 442, a connecting strip 443 and a plug 444. The mounting frame 441 is fixedly connected to the outer side of the hopper 41, the second cylinder 442 is installed on the outer side of the mounting frame 441, the connecting strip 443 is fixedly arranged at the telescopic end of the second cylinder 442, and the plug 444 is fixedly connected to one end of the connecting strip 443. The hopper 41 has a funnel-shaped structure, and the plug 444 has a conical structure. The outer side of the plug 444 is in close contact with the bottom of the hopper 41, the spring 438 is located inside the sleeve 435, the position of the adsorption magnet 434 corresponds to the control magnet 439, the bottom of the clamping strip 42 has a dovetail structure, and a clamping groove matching it is opened on the inner side of the mounting base 2, and the bottom of the clamping strip 42 is in contact with the top of the weighing sensor 3.

[0025] In this embodiment, the hopper 41 is clamped into the mounting base 2 according to the outer clamping strip 42, the count of the weighing sensor 3 is reset, and then resin powder is added to the hopper 41 according to the amount of resin powder required for stirring, and the amount of resin powder added is accurately guaranteed according to the reading of the weighing sensor 3. Then, stirring work is started inside the stirring tank 1. During the stirring process, the second cylinder 442 is slowly extended to separate the plug 444 from the bottom discharge port of the hopper 41. The powder outflow speed can be effectively controlled according to the separation distance between the plug 444 and the hopper 41, thereby realizing slow and uniform feeding. The top of the connecting strip 443 is a triangular structure, which effectively avoids the problem of insufficient addition caused by powder accumulation.

[0026] Furthermore, when the resin powder adheres and hardens to the inner wall of the hopper 41, making it impossible for the powder to slide down and be added into the mixing tank 1, the first cylinder 432 extends, and when the first cylinder 432 is in a contracted state, the adsorption magnet 434 and the control magnet 439 are in an adsorption state. As the first cylinder 432 extends, the pull plate 433 drives the adsorption magnet 434 to pull outward, thereby pulling the pull rod 436 out of the sleeve 435. At this time, the spring 438 is compressed and contracts until the magnetic force can no longer withstand the elastic force of the spring 438 to reset. The spring 438 resets instantly, popping out the knocking ball 437, causing the knocking ball 437 to hit the surface of the hopper 41, thereby generating vibration to shake off the resin powder adhered to the inner wall, thereby ensuring that sufficient resin powder is added.
