Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, specifically to a powder coating production system that allows for the reuse of ultrafine powder. Background Technology

[0002] Powder coatings are in the form of fine powders, named for their solvent-free nature, and are characterized by being harmless, highly efficient, resource-saving, and environmentally friendly. The production process generally involves mixing raw materials in a premixing pan, then melting and extruding them through an extruder, followed by crushing, and finally sieving to obtain the finished product. To prevent unevenness or clumping in subsequent use, ultrafine powders are sieved out. However, due to the diverse colors of powder coatings, these ultrafine powders are usually only reused at a lower grade, resulting in significant raw material waste and poor practicality during mass production.

[0003] In the prior art, such as the powder coating production system for reusable ultrafine powder described in patent number CN218518971U, there is a raw material mixing unit, an extruder, a crushing unit, a separation unit, and a recycling unit; the raw materials sequentially pass through the mixing unit, extruder, crushing unit, and separation unit. The recycling unit includes a recovery tank and a dyeing device. The recovery tank can store the ultrafine powder screened out in the separation unit. The dyeing device has an inlet, an outlet, and a feed port for adding pigment. The inlet of the dyeing device is connected to the recovery tank, and the outlet of the dyeing device is connected to the raw material mixing unit. The dyeing device can mix the incoming ultrafine powder and pigment, and then transfer the mixed ultrafine powder to the raw material mixing unit.

[0004] Although the aforementioned patent can recycle and reuse ultrafine powder in powder coatings, some problems still exist. Some agglomerated and lumpy raw materials may be present in the raw materials required for powder coating production. These raw materials may affect the uniformity of subsequent raw material mixing, thereby affecting the production quality of powder coatings. Therefore, this utility model provides a powder coating production system that allows for the reuse of ultrafine powder. Utility Model Content

This system solves the problem that some raw materials required for powder coating production may contain agglomerated or lumpy particles, which could affect the uniformity of subsequent raw material mixing and thus impact the production quality of the powder coating.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a powder coating production system for reusable ultrafine powder, including a crushing chamber, a screening chamber fixedly installed on the outer wall of the crushing chamber, a feeding component provided at the bottom of the crushing chamber, and a screening component provided on the inner wall of the screening chamber;

[0008] The screening assembly includes two fixed plates, each with two springs fixedly installed at its top end. A screening plate is fixedly installed at the top end of each of the four springs. A cam is provided below the screening plate, and a round rod is fixedly installed on the outer wall of the cam.

Two rotating rods are rotatably installed on the inner wall of the crushing chamber, and a set of crushing rods is installed on the outer wall of each of the two rotating rods. The two sets of crushing rods are arranged alternately.

[0010] Preferably, one end of the outer wall of each of the two rotating rods penetrates the outer wall of the crushing chamber and is fixedly mounted with a gear. The two gears are meshed with each other. A first motor is fixedly mounted on the outer wall of the crushing chamber. The output end of the first motor penetrates the inner wall of the crushing chamber and is fixedly connected to one end of the rotating rod.

[0011] Preferably, the mounting bracket is fixedly installed on the outer wall of the crushing chamber, and the outer wall of the bidirectional screw is threaded with two first connecting sliders, which are respectively fixedly connected to two opening and closing plates.

[0012] Preferably, a bracket is fixedly installed at the bottom of the crushing chamber, a slide rod is fixedly installed on the inner wall of the bracket, and two second connecting sliders are slidably installed on the outer wall of the slide rod.

[0014] Beneficial effects

[0015] This invention provides a powder coating production system for recyclable ultrafine powder. Compared with the prior art, it has the following advantages:

[0016] 1. This ultrafine powder reusable powder coating production system, when the crushing chamber crushes the raw material, the falling material enters the screening chamber. One end of the round rod is connected to the outer wall of one of the gears via a drive wheel and belt. Therefore, when the rotating rod rotates, it drives the round rod to rotate, which in turn drives the cam to rotate. During the rotation of the cam, its edge continuously presses against the bottom of the screening plate. Since the screening plate is connected to the fixed plate by four springs, under the pressure of the cam and the elasticity of the springs, the screening plate vibrates up and down, screening the raw material falling on the screening plate. This prevents the raw material from accumulating, improves the screening efficiency, and allows raw materials that meet the particle size requirements to pass through the screening plate into subsequent processes, while larger particles remain on the screening plate, thereby improving the quality of subsequent powder raw material processing.

[0017] 2. This ultrafine powder reusable powder coating production system, after the raw material is crushed, starts the second motor, causing the bidirectional screw to rotate. The two first connecting sliders threaded to the screw move in opposite directions, thereby opening the fixedly connected opening and closing plate. The crushed raw material falls through the discharge port at the bottom of the crushing chamber. Simultaneously, during the movement of the opening and closing plate, the fixedly connected second connecting slider slides on a sliding rod, providing auxiliary support and guidance to ensure smooth movement of the opening and closing plate. The feeding assembly controls the opening and closing of the plate through the bidirectional screw, enabling precise control of the feeding amount. Furthermore, the smooth movement of the opening and closing plate with the assistance of the sliding rod ensures a smooth feeding process and improves production efficiency.

[0024] 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.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-5 The first embodiment is shown: a powder coating production system for reusable ultrafine powder, including a crushing chamber 1, a screening chamber 6 fixedly installed on the outer wall of the crushing chamber 1, a feeding component 5 provided at the bottom of the crushing chamber 1, and a screening component 7 provided on the inner wall of the screening chamber 6.

[0027] The feeding assembly 5 includes two opening and closing plates 51 and a mounting bracket 52. The top of the mounting bracket 52 is fixedly mounted with a housing 53, and a bidirectional screw 54 is rotatably mounted on the inner wall of the housing 53.

[0028] The screening assembly 7 includes two fixed plates 75, each with two springs 76 fixedly mounted on its top end. A screening plate 77 is fixedly mounted on the top end of the four springs 76. A cam 74 is provided below the screening plate 77. A round rod 73 is fixedly mounted on the outer wall of the cam 74. One end of the outer wall of the round rod 73 is rotatably mounted on the outer wall of the screening chamber 6. When the cam 74 rotates, the screening plate 77 can be made to sway up and down with the cooperation of the springs 76.

[0029] The bottom of the crushing chamber 1 is provided with a discharge port. Two opening and closing plates 51 are fitted to the bottom of the crushing chamber 1 to cover the discharge port. Two rotating rods 2 are rotatably installed on the inner wall of the crushing chamber 1. A set of crushing rods is installed on the outer wall of each of the two rotating rods 2. The two sets of crushing rods are staggered to prevent the crushing rods from colliding with each other when rotating.

[0030] One end of each of the two rotating rods 2 penetrates the outer wall of the crushing chamber 1 and is fixedly mounted with a gear 3. The two gears 3 are meshed with each other. A first motor 4 is fixedly mounted on the outer wall of the crushing chamber 1. The output end of the first motor 4 penetrates the inner wall of the crushing chamber 1 and is fixedly connected to one end of the rotating rod 2. When the first motor 4 is turned on, it can drive the rotating rod 2 to rotate. The rotating rod 2 can drive the other rotating rod 2 to rotate through the two meshing gears 3.

[0031] Figures 1-5The second embodiment is shown. The main difference from the first embodiment is that the mounting bracket 52 is fixedly installed on the outer wall of the crushing chamber 1, and the outer wall of the bidirectional screw 54 is threaded with two first connecting sliders 55. The two first connecting sliders 55 are fixedly connected to the two opening and closing plates 51 respectively.

[0032] A bracket 58 is fixedly installed at the bottom of the crushing chamber 1. A slide rod 57 is fixedly installed on the inner wall of the bracket 58. Two second connecting sliders 59 are slidably installed on the outer wall of the slide rod 57. The two second connecting sliders 59 are fixedly connected to two opening and closing plates 51 respectively. The second connecting sliders 59 can support the opening and closing plates 51. With the cooperation of the slide rod 57, the opening and closing plates 51 can move smoothly. A second motor 56 is fixedly installed on the outer wall of the housing 53. The output shaft of the second motor 56 passes through the inner wall of the housing 53 and is fixedly connected to one end of the outer wall of the bidirectional screw 54. The second motor 56 can drive the bidirectional screw 54 to rotate. The bidirectional screw 54 can then drive the opening and closing plates 51 to open through the first connecting slider 55, thereby controlling the feeding speed of the crushed raw materials.

[0033] One end of the outer wall of the round rod 73 and one of the outer walls of the gears 3 are fixedly installed with a drive wheel 71. The outer walls of the two drive wheels 71 are fitted with belts 72. The top of the screening plate 77 is fixedly installed with a fixing frame 78. The screening plate 77 is movably inserted into the inner wall of the screening chamber 6. The fixing frame 78 at the top of the screening plate 77 serves as a barrier to prevent the raw materials from spilling during the screening process.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, to prevent the presence of lumps in the raw materials from affecting subsequent production quality, the raw materials are added to the crushing chamber 1, and the first motor 4 is started. Its output end drives the rotating rod 2 connected to it to rotate. Since the gears 3 on the outer walls of the two rotating rods 2 mesh with each other, the other rotating rod 2 will also rotate in the opposite direction. The crushing rods on the two rotating rods 2, which are intersecting each other, crush the raw materials entering the crushing chamber 1, breaking any agglomerated raw materials into small particles, ensuring that the particle size of the raw materials meets the requirements of subsequent processing. After the raw materials are crushed, the bidirectional screw 54 inside the machine housing 53 is started. When the bidirectional screw 54 rotates, the two first connecting sliders 55 that are threaded to it will move in opposite directions on the bidirectional screw 54, thereby driving the opening and closing plate 51 that is fixedly connected to it to open. The crushed raw materials fall through the discharge port at the bottom of the crushing chamber 1. Meanwhile, during the movement of the opening and closing plate 51, the second connecting slider 59, which is fixedly connected to it, will slide on the slide rod 57, playing an auxiliary support and guiding role, ensuring that the opening and closing plate 51 moves smoothly. The feeding component 5 controls the opening and closing of the opening and closing plate 51 through the bidirectional screw 54, which can accurately control the feeding amount. Moreover, the opening and closing plate 51 moves smoothly with the assistance of the slide rod 57, ensuring the smooth feeding process and improving production efficiency. One end of the round rod 73 is connected to the outer wall of one of the gears 3 through the transmission wheel 71 and the belt 72. Therefore, when the rotating rod 2 rotates, it will drive the round rod 73 to rotate, and the round rod 73 will drive the cam 74 to rotate. During the rotation of cam 74, its edge continuously presses against the bottom of screening plate 77. Since screening plate 77 is connected to fixed plate 75 by four springs 76, screening plate 77 vibrates up and down under the pressure of cam 74 and the elasticity of springs 76, screening the raw materials falling on screening plate 77, thereby preventing the accumulation of raw materials and improving the screening efficiency of raw materials. Raw materials that meet the particle size requirements pass through screening plate 77 and enter the subsequent process, while larger particles remain on screening plate 77, thereby improving the quality of subsequent production and processing of powder raw materials.
