Description

Technical Field

[0001] This invention relates to the field of coating processing technology, specifically to a batching device for processing sand-textured black powder coating. Background Technology

[0002] Sand-textured black powder coatings possess a unique sand-textured effect. Typically black, they form a tough coating with a sand-textured finish and are commonly used for surface decoration and protection of metal products. The main components of sand-textured black powder coatings are epoxy resin or polyester resin, with added special pigments, fillers, and curing agents. They offer advantages such as a unique sand-textured effect, wear and corrosion resistance, good adhesion, and environmental friendliness and energy efficiency.

[0003] Referring to a batching device and method for powder coating production (Chinese Patent Publication No. CN115090207A), this invention utilizes a first feeding mechanism for conveying and batching raw materials in flake, columnar, or large particle form, such as resins and curing agents, and a second feeding mechanism for conveying and batching raw materials in powder or small particle form, such as pigments, fillers, and additives. Both the batching and conveying of powder raw materials are completed in a closed environment, using semi-automatic pipeline transport. This eliminates the need for manual contact with the powder, ensuring good sealing, reducing dust emissions, improving working conditions, and preventing skin allergies caused by contact. Furthermore, the device of this invention has a simple structure, is easy to lay out and maintain, and allows for arbitrary selection of the conveying path, facilitating the transformation and upgrading of powder coating plants.

[0004] A comprehensive analysis of the above patents reveals the following deficiencies:

[0005] Traditional paint mixing processes require measuring the required amount of each component one by one and then adding them to the mixing device for mixing. This process is repetitive, tedious, inefficient, and has a low degree of automation, making it unsuitable for mass paint production.

[0006] The mixing process can easily lead to misremembering the ingredients that have already been added, resulting in incorrect ingredient addition and failure of the paint mixing ratio, which in turn leads to waste of raw materials.

[0007] To address these issues, the present invention proposes a batching device for processing sand-textured black powder coatings. Summary of the Invention

This process is repetitive, cumbersome, inefficient, and has a low degree of automation, making it unsuitable for large-scale coating production. Furthermore, the batching process is prone to errors in remembering the added raw material components, leading to incorrect batching and coating ratio failure, which in turn results in raw material waste.

[0019] Beneficial effects

[0020] This invention provides a batching device for processing matte black powder coatings. Compared with the prior art, it has the following advantages:

[0021] 1. A batching device for processing sand-textured black powder coating, comprising a support plate fixedly connected to the top of a mixing tank for providing a support platform, wherein a feeding notch is provided on one side of the top of the support plate for adding sand-textured black powder coating raw materials to the mixing tank, and a power mechanism for providing driving force is fixedly installed at the center of the top of the support plate, the power mechanism including a motor housing and a servo motor fixedly installed inside the motor housing, the output shaft of the servo motor rotating through the motor housing and extending to the outside, a circular plate fixedly sleeved on the outer wall of the output shaft, and a proportioning mechanism for proportioning sand-textured black powder coating evenly fixedly installed on the outer wall of the circular plate, the proportioning mechanism including a support arm and a batching mechanism fixedly connected to one end of the support arm, the end of the support arm away from the batching mechanism being fixedly connected to the outer wall of the circular plate, and an internal gear ring and an arc-shaped top block fixedly connected to the top of the support plate, the internal gear ring being used to mesh with the batching mechanism. The system is connected to drive the batching mechanism to complete the initial mixing of the sand-textured black powder coating. An arc-shaped protrusion is fixedly set on one side of the feed notch to control the fixed-point discharge of the batching mechanism, so as to complete the transfer of the sand-textured black powder coating from the batching mechanism to the mixing tank. The mixing tank is equipped with a stirring mechanism for secondary mixing of the sand-textured black powder coating. A hanger is fixedly set on the top of the support plate, and multiple storage mechanisms for providing sand-textured black powder coating raw materials to the batching mechanism are evenly arranged on the side wall of the hanger. This solves the problem that the traditional coating batching process requires measuring the required amount of each component one by one and then adding it to the batching device for mixing. The process is repetitive, cumbersome, inefficient, and has a low degree of automation, making it unsuitable for large-scale coating production. The batching process is also prone to misremembering the raw material components that have been added, resulting in incorrect batching and coating ratio failure, which in turn leads to raw material waste.

[0022] 2. A batching device for processing sand-textured black powder coatings, comprising multiple batching mechanisms arranged in a ring array, which, when passing through a storage mechanism, utilizes a lifting strip to lift a conical cover plate, thereby opening the discharge pipe. This allows the raw material in the storage tank to automatically fall into the batching mechanism within a certain timeframe, enabling automatic material retrieval. Secondly, while the lifting strip contacts the arc-shaped protrusion, a fourth gear meshes with an arc-shaped rack. The rotation of the batching mechanism, driven by the arc-shaped rack, drives the fourth gear, which in turn drives the transmission shaft. The synchronous rotation of the spiral blades pushes the coating material downwards, agitating it and preventing blockage of the discharge port, ensuring smooth discharge. Furthermore, the rotation of the transmission shaft is achieved by the arc-shaped rack in the batching mechanism driving the fourth gear, creating a linkage between the two. This eliminates the need for a separate drive device for the transmission shaft, saving costs and simplifying the structure for easier inspection and maintenance.

[0023] 3. A batching device for processing sand-textured black powder coating, which, by setting a height adjustment mechanism, allows the lifting sleeve to slide a certain distance relative to the measuring block, changing the total length of the measuring block and the lifting sleeve, thereby changing the total length of the drive shaft. Since the height of the lifting block is fixed, changing the height of the height adjustment component can correspondingly change the height at which the drive shaft is lifted, and thus change the height of the conical cover plate relative to the discharge pipe. The greater the upward movement of the conical cover plate, the larger the gap between its bottom and the discharge pipe, and the more coating material is discharged per unit time. Conversely, the smaller the upward movement of the conical cover plate, the smaller the gap between its bottom and the discharge pipe, and the less coating material is discharged per unit time, thus achieving the purpose of controlling the amount of coating discharged. Therefore, it can... According to different mixing ratios of paint ingredients, the height of the height adjustment component is adjusted accordingly to ensure that the amount of paint material falling per unit time meets the mixing ratio. Secondly, by setting scale lines on the measuring block, the height of the lifting sleeve can be adjusted with reference to the scale lines. Moreover, the limit groove is set correspondingly to the scale lines. After the lifting sleeve slides to the set height, the position of the lifting sleeve can be locked by the positioning block and the limit groove to ensure the accuracy of the height adjustment of the lifting sleeve. Furthermore, the distance that the lifting sleeve slides relative to the measuring block is correlated with the amount of paint discharged. That is, for every scale line that the lifting sleeve slides up, the amount of paint passing through the discharge pipe per unit time increases linearly, and vice versa, thereby achieving the purpose of accurately releasing paint material.

[0024] 4. A batching device for processing sand-textured black powder coating, which, by setting two support frames and a second spring between the two support frames, can compress the second spring when the drive shaft moves upward. After the bottom of the height adjustment component loses its force, the elastic force of the second spring can quickly push the drive shaft downward, so that the conical cover plate can quickly block the discharge pipe, avoid leakage of coating raw materials, and ensure the accuracy of the coating batching process.

[0025] 5. A batching device for processing sand-textured black powder coating, wherein a first gear and an internal gear ring are meshed in the batching mechanism. The first gear is driven by the internal gear ring to rotate. The first stirring rod can pre-stir the coating raw materials inside, which facilitates the acceleration of the subsequent stirring speed of the coating. Moreover, there is no need to set up a separate power device for the rotation of the stirring rod, saving the cost of setting up a power device. Secondly, after the batching mechanism passes the arc-shaped top block, the sealing component can be pushed by the arc-shaped top block to make the discharge port and the through hole face each other, so as to achieve the purpose of automatically releasing the coating. Thus, the coating that has been pre-stirred can enter the mixing tank through the feed notch, which facilitates the subsequent further stirring of the coating.

[0026] 6. A batching device for processing sand-textured black powder coating, which, by setting up a stirring mechanism, utilizes a servo motor to drive a second gear to rotate, thereby synchronously driving multiple third gears to rotate, realizing the driving of multiple second stirring rods, and thus using the second stirring rods to stir the coating in the mixing tank. The second gear and other components share a single servo motor, saving the cost of setting up multiple motors, and making the structure simpler and easier for subsequent inspection and maintenance. Secondly, the batching mechanism and the storage mechanism work together to realize automatic material picking and automatic release of coating raw materials, improving the coating mixing efficiency, which is beneficial for large-scale coating production. Furthermore, the coating mixing process does not require manual weighing and addition, avoiding human error and ensuring the smooth progress of coating mixing. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides four technical solutions:

[0042] like Figure 1-3The first embodiment is shown: a batching device for processing sand-textured black powder coating, including a secondary mixing tank assembly. The secondary mixing tank assembly includes a mixing tank 1, a discharge pipe 2 fixedly connected to the bottom of the mixing tank 1 for discharging sand-textured black powder coating, and a feed inlet 3 opened at the top of the mixing tank 1. A support plate 4 for providing a support platform is fixedly connected to the top of the mixing tank 1. A feed notch 5 is opened on one side of the top of the support plate 4 for adding sand-textured black powder coating raw materials to the mixing tank 1. A power mechanism for providing driving force is fixedly installed at the center position of the top of the support plate 4. The power mechanism includes a motor housing 6 and a servo motor fixedly installed inside the motor housing 6. The output shaft of the servo motor rotates through the motor housing 6 and extends to the outside. A circular plate 7 is fixedly sleeved on the outer wall of the output shaft. A proportioning mechanism for proportioning sand-textured black powder coating is uniformly fixedly installed on the outer wall of the circular plate 7. The proportioning mechanism includes a support arm 8 and a batching mechanism 9 fixedly connected to one end of the support arm 8. The end of the support arm 8 away from the batching mechanism 9 is fixedly connected to the circular plate 7. On the outer wall of plate 7, an internal gear ring 10 and an arc-shaped top block 11 are fixedly connected to the top of the bearing plate 4. The internal gear ring 10 is used to mesh with the batching mechanism 9 to drive the batching mechanism 9 to complete the initial mixing of the sand texture black powder coating. The arc-shaped top block 11 is fixedly set on one side of the feed notch 5 to control the batching mechanism 9 to discharge material at a fixed point, so as to complete the transfer of the sand texture black powder coating in the batching mechanism 9 to the mixing tank 1. The mixing tank 1 is equipped with a stirring mechanism 12 for secondary mixing of the sand texture black powder coating. 4. A hanger 13 is fixedly installed at the top. Multiple storage mechanisms 14 for supplying raw materials of sand texture black powder coating to the batching mechanism 9 are evenly arranged on the side wall of the hanger 13. The inner tooth ring 10 and the feed notch 5 are disconnected to avoid affecting the rotation of the batching mechanism 9. The bottom of the inner cavity of the mixing tank 1 is funnel-shaped to ensure that the coating is collected at the bottom of the funnel and can be quickly discharged through the discharge pipe 2. A control box is fixedly connected to the outer wall of the mixing tank 1 to control the electrical equipment in the batching device.

[0043] like Figure 4-7The second embodiment is shown, and its main difference from the first embodiment is that: a batching device for processing sand-textured black powder coating, the batching mechanism 9 includes a storage cylinder 91 and a receiving hopper 92 fixedly connected to the top of the storage cylinder 91, and a drive assembly 93 disposed on the outer wall of the receiving hopper 92. A circular partition is fixedly connected inside the storage cylinder 91, and a through hole 94 for the coating raw material to pass through is opened at the top of the circular partition. Two through grooves 95 are symmetrically opened on both sides of the outer wall of the storage cylinder 91 and below the circular partition. Two discharge ports 96 connected to the through grooves 95 are respectively opened on both sides of the bottom of the storage cylinder 91. A seal for controlling the opening and closing of the discharge ports 96 is slidably connected inside the two through grooves 95. Component 97, the storage cylinder 91 is rotatably connected to a mixing component for preliminary mixing of sand texture black powder coating. Guide rods 910 are fixedly connected to both sides of the outer wall of the storage cylinder 91. A first spring 911 is slidably sleeved on the outer wall of the guide rod 910. A spring baffle is fixedly connected to the end of the guide rod 910 away from the storage cylinder 91 to prevent the first spring 911 from disengaging from the guide rod 910. The radius of the circle formed by the two discharge ports 96 when they rotate is equal to the radius of the circle where the feed notch 5 is located. That is, when the discharge port 96 rotates, it just sweeps over the top of the feed notch 5. Under the push of the arc-shaped top block 11, the first baffle 971 can be pushed so that the discharge port 975 and the through hole 94 coincide, so as to achieve the purpose of automatic release of coating. The mixing component includes a first stirring rod 98, a first gear 99 fixedly connected to the bottom end of the first stirring rod 98, and stirring blades fixedly connected to the outer wall of the first stirring rod 98. The bottom end of the first stirring rod 98 rotates through the storage cylinder 91 and extends to the outside. The first gear 99 meshes with the internal gear ring 10. The sealing assembly 97 includes a first baffle 971 and a second baffle 972 arranged opposite to each other. A side plate 973 is fixedly connected to one end of the first baffle 971 and the second baffle 972, and an arc-shaped plate 974 is fixedly connected to the other end of the first baffle 971 and the second baffle 972. A discharge port 975 is opened at the bottom of both the first baffle 971 and the second baffle 972. The first baffle 971 and the second baffle 972 are slidably connected inside the two through slots 95, respectively. The side plate 973 is slidably sleeved on the outer wall of the guide rod 910. The first spring 911 is located between the side plate 973 and the spring baffle. For a period of time after the arc-shaped plate 974 and the arc-shaped top block 11 meet, the discharge port 975 and the through hole 94 are opposite each other, so that the paint is continuously discharged from the storage cylinder 91. The drive assembly 93 includes a lifting strip 931 fixedly connected to the top of the receiving hopper 92 and an arc-shaped rack 932 fixedly connected to the side wall of the storage cylinder 91 by a bracket.

[0044] like Figure 8The third embodiment is shown, and the main difference from the second embodiment is that: a batching device for processing sand texture black powder coating, the stirring mechanism 12 includes a second gear 121 fixedly sleeved on the outer wall of the output shaft of the servo motor, a plurality of third gears 122 meshing around the outer wall of the second gear 121, and a second stirring rod 123 fixedly connected to the bottom of the third gear 122. The second stirring rod 123 rotates through the support plate 4 and extends into the mixing tank 1 for secondary stirring of sand texture black powder coating.

[0045] like Figure 9-12The fourth embodiment is shown, and its main difference from the third embodiment is that: a batching device for processing sand texture black powder coating, the storage mechanism 14 includes a storage tank 141 and a feeding port opened on the top of the storage tank 141 for feeding coating raw materials and a discharge pipe 142 fixedly connected to the bottom of the storage tank 141. A guide pipe 143 for changing the coating conveying direction is fixedly connected to the bottom of the discharge pipe 142. A pushing mechanism for accelerating the discharge of coating raw materials is movably arranged inside the storage tank 141. A height adjustment mechanism 149 for adjusting the length of the drive shaft 144 is provided at the bottom of the pushing mechanism. The feeding mechanism includes a drive shaft 144, a spiral blade 145, a second spring 147, a conical cover plate 148, and two support frames 146. The drive shaft 144 is movably connected inside the storage tank 141. The spiral blade 145 is fixedly sleeved on the outer wall of the drive shaft 144. The two support frames 146 are respectively movably sleeved on the upper and lower sides of the outer wall of the drive shaft 144. A spring lifting plate is fixedly sleeved on the top of the lowermost support frame 146 on the outer wall of the drive shaft 144 for supporting the drive shaft. When 144 moves upward, the spring lifting plate moves upward simultaneously, pushing the second spring 147 upward, causing it to compress and produce elastic deformation. The second spring 147 is sleeved on the outer wall of the drive shaft 144 and located between the two support frames 146. The conical cover plate 148 is movably sleeved on the outer wall of the drive shaft 144 and is used to control the opening and closing of the discharge pipe 142. The two ends of the drive shaft 144 pass through the storage tank 141 and the guide pipe 143, respectively, and the drive shaft 144 can be positioned relative to the guide pipe 143 and the support frame 146. 6. The storage tank 141 rotates and slides. The end of the support frame 146 away from the drive shaft 144 is fixedly connected to the inner wall of the storage tank 141. The bottom of the cavity of the storage tank 141 is funnel-shaped, and the bottom shape of the conical cover plate 148 is adapted to the shape of the funnel. The greater the upward movement of the conical cover plate 148, the larger the gap between the discharge pipe 142 and the conical cover plate 148, and the more paint raw materials are discharged per unit time. Conversely, the smaller the distance between the conical cover plate 148 and the discharge pipe 142, the greater the amount of paint raw materials discharged per unit time. The closer the conical cover plate 148 and the discharge pipe 142 are, the smaller the gap between them, and the less paint is discharged per unit time. The conical cover plate 148 is rotatably connected to the drive shaft 144. The outer wall of the drive shaft 144 is fixedly fitted with limiting plates that restrict the vertical movement of the conical cover plate 148 at the top and bottom of the conical cover plate 148. That is, the conical cover plate 148 can only rotate axially relative to the drive shaft 144. The storage tank 141 is fixedly connected to the inner wall of the hanger 13 by a bracket.The height adjustment mechanism 149 includes a measuring block 1491 fixedly connected to the bottom end of the drive shaft 144, a scale line 1492 formed on the outer wall of the measuring block 1491, and a limiting groove 1493 formed on the outer wall of the measuring block 1491 corresponding to the position of the scale line 1492. A lifting sleeve 1494 is slidably sleeved on the outer wall of the measuring block 1491. Screws 1495 are fixedly connected to both sides of the outer wall of the lifting sleeve 1494. A positioning plate 1496 is slidably sleeved on the outer wall of the screws 1495. A positioning block 1497 adapted to the structure of the limiting groove 1493 is fixedly connected to the outer wall of the positioning plate 1496. The bottom end of the lifting sleeve 1494 is fixed. A fourth gear 1498 is connected, and an arc-shaped protrusion 1499 is rotatably connected to the bottom of the fourth gear 1498. The arc-shaped protrusion 1499 is slidably connected to the top of the lifting strip block 931. Both ends of the lifting strip block 931 are chamfered to facilitate sliding from a lower position to the top of the lifting strip block 931. The height of the arc-shaped rack 932 is much higher than the thickness of the fourth gear 1498, so that the fourth gear 1498 can still mesh with the arc-shaped rack 932 after the height changes. The positioning plate 1496 and the screw 1495 are connected by a nut so that the positioning block 1497 can be embedded in the limiting groove 1493 to determine the position of the measuring block 1491.

[0046] In use, multiple storage mechanisms 14 are first adjusted according to the proportions of the raw materials in the coating. During adjustment, the height adjustment mechanism 149 can slide a certain distance relative to the measuring block 1491 using the lifting sleeve 1494, changing the total length of the measuring block 1491 and the lifting sleeve 1494, thereby changing the total length of the drive shaft 144. Since the height of the lifting strip 931 is fixed, changing the height of the height adjustment mechanism 149 can correspondingly change the height at which the drive shaft 144 is lifted, thereby changing the height of the conical cover plate 148 relative to the discharge pipe 142. The greater the height of the conical cover plate 148, the larger the gap between its bottom and the discharge pipe 142, and the more coating raw materials are discharged per unit time. Conversely, the greater the height of the conical cover plate 148, the smaller the gap between its bottom and the discharge pipe 142, and the more coating raw materials are discharged per unit time. The smaller the gap, the smaller the gap between its bottom and the discharge pipe 142, and the less paint raw material is discharged per unit time. Therefore, the height of the height adjustment mechanism 149 can be adjusted according to different proportions of paint ingredients, so that the amount of paint raw material falling per unit time can meet the proportion. During the adjustment process, the height of the lifting sleeve 1494 is adjusted with reference to the scale line 1492. Moreover, the limit groove 1493 is set to correspond to the scale line 1492. After the lifting sleeve 1494 slides to the set height, the positioning plate 1496 is installed on the screw 1495, and the positioning block 1497 is inserted into the corresponding limit groove 1493 to lock the position of the lifting sleeve 1494. Then, the positioning plate 1496 is locked on the screw 1495 with a nut. The lifting sleeve 1494 is relative to the measuring block. The sliding distance of 1491 is correlated with the paint discharge volume. That is, for every scale mark the lifting sleeve slides up, the amount of paint passing through the discharge pipe per unit time increases linearly by one cubic centimeter, and vice versa. After the storage mechanism 14 is adjusted, the corresponding raw material is added to the storage tank 141, and a raw material label is affixed to the corresponding storage tank 141 for easy identification. Then, the servo motor is started to drive the circular plate 7 to rotate at a uniform low speed. Multiple dispensing mechanisms 9 rotate synchronously. When the dispensing mechanism 9 passes the storage mechanism 14, the lifting elongated block 931 and the arc-shaped protrusion 1499 in the dispensing mechanism 9 meet. The fourth gear 1498 and the arc-shaped rack 932 mesh and connect. Because the lifting elongated block 931 has chamfered ends, the arc-shaped protrusion... Block 1499 slides along the chamfer of one end of the lifting strip 931 to its surface. The drive shaft 144 drives the conical cover plate 148 to rise synchronously, creating a gap between the conical cover plate 148 and the discharge pipe 142. The arc-shaped rack 932 drives the fourth gear 1498 to rotate. When the spiral blade 145 rotates, it pushes the paint material from the gap between the discharge pipe 142 and the conical cover plate 148 and slides through the guide pipe 143 into the receiving hopper 92. When the arc-shaped protrusion 1499 and the lifting strip 931 disengage, the second spring 147 pushes the drive shaft 144 downward. The conical cover plate 148 seals the top of the discharge pipe 142, and the paint material falls into the storage cylinder 91. The dispensing mechanism 9 passes through multiple storage mechanisms 14 containing different paint materials in succession.Different raw materials fall into the storage cylinder 91. Because the first gear 99 and the internal gear ring 10 are meshed, during the rotation of the batching mechanism 9, the internal gear ring 10 drives the first gear 99 to rotate, thereby causing the first stirring rod 98 to stir the raw materials in the storage cylinder 91. When the batching mechanism 9 and the arc-shaped top block 11 meet, the sealing component 97 slides along the through groove 95. When it slides to its limit position, the discharge port 975 meets the through hole 94. The paint in the storage cylinder 91, after preliminary stirring, enters the mixing tank 1 through the feed notch 5. Simultaneously, the servo motor drives the second gear 121 to rotate. Since multiple third gears 122 are meshed with the second gear 121, the rotation of the second gear 121 can drive the rotation of multiple third gears 122. The second stirring rod 123 stirs the paint raw materials in the mixing tank 1. After stirring for a set time, the discharge pipe 2 is opened to discharge the paint for filling and storage.
