Coating raw material processing pretreatment device

Abstract

This utility model relates to the field of coating raw material processing technology, and in particular to a pretreatment device for coating raw material processing. It includes a main body mechanism for effectively crushing materials, a feeding mechanism for automatically feeding incompletely crushed materials on one side of the main body mechanism, and a separation mechanism at the bottom of the main body mechanism. This utility model, by setting up a feeding mechanism, enables the device to automatically perform secondary crushing on materials that do not meet the crushing specifications. The crushed materials are screened through a sieve plate. The inclined angle of the sieve plate allows materials that meet the crushing specifications to pass through the sieve plate, while materials that do not meet the crushing specifications slide down to one side of the sieve plate and fall into a collection container. A micro motor drives a screw to rotate, causing the collection container to rise steadily under the action of a limiting rod until it reaches an inclined plate where the limiting action is lost, causing the sealing plate to fall to one side, allowing the internal materials to automatically fall back into the inlet. This saves time and effort and improves the processing efficiency of the device.

Description

Technical Field

[0001] This utility model relates to the field of coating raw material processing technology, specifically to a coating raw material processing pretreatment device. Background Technology

[0002] The thin film formed by coatings can isolate corrosive media such as air, moisture, and ultraviolet rays, preventing metal corrosion, wood decay, or cement weathering, thus extending the service life of objects. Its main fixed raw materials include fillers, pigments, and metal substrates, and its pretreatment directly determines the coating performance. In existing technologies, to improve the dispersion uniformity and hiding power of coatings, solid raw materials need to be pulverized using a pulverizer. However, the particle size range of the pulverized material is quite large. After one processing, workers need to collect and screen the particles, thus re-feeding and pulverizing particles that do not meet the pulverization requirements, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pretreatment device for coating raw materials, which has the advantages of automatically feeding material particles that do not meet the crushing requirements, saving time and labor. It solves the problem in existing technologies where, after the material is processed once, workers need to collect and screen the particles, and then feed the particles that do not meet the crushing requirements back into the material for crushing, which is time-consuming and labor-intensive.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pretreatment device for coating raw materials includes a main body for effectively crushing materials. A feeding mechanism for automatically feeding incompletely crushed materials is located on one side of the main body. A separation mechanism for separating materials is located at the bottom of the main body. The feeding mechanism includes a base plate, a guide rod fixedly connected to the base plate, and a screw rotatably connected to the base plate. A micro motor for driving the screw is installed inside the base plate. A collection container is located on the top of the base plate. Two connecting blocks are fixedly connected to one side of the collection container; one connecting block is threadedly connected to the screw, and the other connecting block is slidably connected to the guide rod. A sealing plate is rotatably connected to the bottom side of the collection container. A support plate is fixedly connected to the base plate, and a limiting rod for limiting the sealing plate is fixedly connected to the support plate. An inclined plate for supporting the sealing plate is fixedly connected to the top of the limiting rod.

[0005] Preferably, the angle between the bottom of the collection container and the horizontal plane is the same as the angle between the inclined plate and the horizontal plane, and baffles to prevent material leakage are fixedly connected to both sides of the inclined plate, and the angle between the sieve plate and the horizontal plane is 30°.

[0006] Preferably, the separation mechanism includes a sieve plate, two support plates are fixedly connected to the bottom plate, and a stop block is fixedly connected to one side of each of the two support plates. Two fixing blocks are fixedly connected to the bottom of the sieve plate, and an inclined block for easy collection of crushed material is installed at the top of the bottom plate between the two support plates.

[0007] Preferably, when the sieve plate is installed, the two fixing blocks are respectively attached to the two stop blocks, and at this time the support plate is located on one side of the bottom of the sieve plate.

[0008] Preferably, the main body includes an outer shell fixedly connected to the top of two support plates, the top of the outer shell is provided with a feed inlet, and two crushing rollers are installed inside the outer shell.

[0009] Preferably, some parts of the housing are equipped with gears that are fixedly connected to the two crushing rollers, and a servo motor for driving one of the crushing rollers is installed on the other side of the housing.

[0010] By means of the above technical solution, this utility model provides a pretreatment device for coating raw materials, which has at least the following beneficial effects: 1. This utility model enables the device to automatically perform secondary crushing on materials that do not meet the crushing specifications by setting a feeding mechanism. The crushed materials are screened by a screen plate. The inclined angle of the screen plate allows materials that meet the crushing specifications to pass through the screen plate, while materials that do not meet the crushing specifications slide down to one side of the screen plate and fall into the collection container. A micro motor drives the screw to rotate, causing the collection container to rise steadily under the action of the limiting rod until it reaches the inclined plate and loses the limiting effect, causing the sealing plate to fall to one side, so that the internal materials automatically fall back into the feed port, saving time and effort and improving the processing efficiency of the device.

[0011] 2. This utility model enables the effective collection of materials that meet the crushing specifications by setting a separation mechanism. The collection space is automatically formed by the support plate, two support plates and inclined blocks, so that the material passing through the screen plate can automatically fall above the inclined blocks and slide to one side. At the same time, the screen plate can be easily disassembled and assembled by the stop block and the fixing block, which greatly improves the simplicity of the device. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] In the prior art, in order to improve the dispersion uniformity and hiding power of coatings, solid raw materials need to be crushed by a crusher. However, the size range of the crushed material particles is relatively large. After one processing, the workers need to collect and screen the particles, so that the particles that do not meet the crushing requirements can be re-fed and crushed, which is time-consuming and labor-intensive. The following describes some embodiments of the coating raw material processing pretreatment device provided by this utility model with reference to the accompanying drawings.

[0016] Example 1: In order to effectively process the raw materials of coatings, combined with Figures 1-4 As shown, a pretreatment device for coating raw materials is proposed. The device consists of a main body 1 for effectively crushing materials, a feeding mechanism 2 on one side of the main body 1 for automatically feeding incompletely crushed materials, and a separation mechanism 3 at the bottom of the main body 1 for easily separating materials.

[0017] To automatically collect and feed incompletely crushed materials, a feeding mechanism 2 is proposed. This mechanism comprises a base plate 201, on which a guide rod 202 is fixedly connected. A screw 203 is rotatably connected to the base plate 201. A micro motor for driving the screw 203 is installed inside the base plate 201. A collection container 205 is located on top of the base plate 201. Two connecting blocks 204 are fixedly connected to one side of the collection container 205. One connecting block 204 is threadedly connected to the screw 203, and the other connecting block 204 is slidably connected to the guide rod 202. A sealing plate 206 is rotatably connected to the bottom side of the collection container 205. A support plate is fixedly connected to the base plate 201. A limiting rod 207 for limiting the sealing plate 206 is fixedly connected to the support plate. An inclined plate 208 for supporting the sealing plate 206 is fixedly connected to the top of the limiting rod 207. The angle between the bottom of the collection container 205 and the horizontal plane is the same as the angle between the inclined plate 208 and the horizontal plane. Both sides of the inclined plate 208 are fixedly connected with baffles to prevent material leakage. The crushed material is screened by the screen plate 301. The inclined angle of the screen plate 301 causes the material that does not meet the crushing specifications to slide down to one side of the screen plate 301 and fall into the collection container 205. The screw 203 driven by the micro motor rotates, causing the collection container 205 to rise steadily along the limiting rod 207 under the action of the guide rod 202. When it reaches the inclined plate 208, it loses the support of the limiting rod 207, causing the sealing plate 206 to fall automatically onto the inclined plate 208, so that the internal material automatically falls back into the feed port 102. The baffles prevent material leakage, thus completing the automatic feeding of materials, saving time and effort, and improving the processing efficiency of the device.

[0018] Example 2: Based on Example 1, the technical solution proposed in Example 1 is used to solve the problem that the particle size of the crushed material in the prior art has a large range. After one processing, the staff needs to collect and screen the particles, so that the particles that do not meet the crushing requirements can be re-fed and crushed, which is time-consuming and labor-intensive. However, after the sieve plate 301 has been used for a long time, some of its sieve holes are prone to blockage. In order to ensure its screening effect, the sieve plate 301 should be easy to disassemble, clean and replace.

[0019] To ensure the screening effect of sieve plate 301, combined with Figure 1 and Figure 3 as well as Figure 4As shown, a separation mechanism 3 is proposed. A screen plate 301 is provided, and two support plates are fixedly connected to the base plate 201. Each of the two support plates has a stop block 304 fixedly connected to one side of its opposite side. Two fixing blocks 303 are fixedly connected to the bottom of the screen plate 301. An inclined block 302 for easy collection of crushed material is installed between the two support plates at the top of the base plate 201. The support plates, the inclined block 302, and the support plate automatically form a collection space, allowing material passing through the screen plate 301 to automatically fall onto the inclined block 302 and slide to one side. Pulling the screen plate 301 separates the two fixing blocks 303 from the two stop blocks 304. When the screen plate 301 is installed, the two fixing blocks 303 are in contact with the two stop blocks 304, thus limiting and fixing the position of the screen plate 301. This allows for easy disassembly and assembly of the screen plate 301, facilitating cleaning and replacement by staff.

[0020] To effectively crush materials, a main body mechanism 1 is proposed. A housing 101 is fixedly connected to the top of two support plates. The top of the housing 101 has a feed inlet 102. Two crushing rollers 103 are installed inside the housing 101. Gears fixedly connected to the two crushing rollers 103 are mounted on some parts of the housing 101. A servo motor for driving one crushing roller 103 is installed on the other side of the housing 101. The servo motor drives one crushing roller 103 to rotate. The meshing of the two gears causes the two crushing rollers 103 to cooperate in crushing the material, ensuring the crushing effect.

[0022] 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 these 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.
