Description

Technical Field

[0001] The present invention relates to the technical field of pigment proportioning equipment, and particularly to an automatic proportioning equipment for inorganic pigment production. Background Art

[0002] Inorganic pigments are pigments composed of metals, metal oxides or metal salts, which are processed by processes such as high-temperature calcination and grinding, and the final products are generally in powder form. Due to their good stability, bright colors, and non-fading properties, inorganic pigments are widely used in industries such as coatings, inks, plastics, rubbers, and ceramics. In the early stage of inorganic pigment production, it is necessary to mix various mineral raw materials of different colors in a certain proportion to obtain the required color.

[0003] During actual production, the raw materials fall from the storage bin into the batching barrel, and then a stirring device is used to stir and mix the raw materials of various colors. However, since the mineral raw materials are in powder form and have poor fluidity, and the feed inlet of the raw materials is usually opened at the edge position of the batching barrel, the raw materials can only fall on the edge area inside the batching barrel when falling from the storage bin, resulting in low space utilization rate inside the barrel. Although the raw materials can be stirred and spread by the stirring device, there is too much material piled up in the edge area of the barrel, and the time required for the stirring device to fully disperse it inside the batching barrel will increase. Moreover, due to the low fluidity of the powder, the accumulation of a large amount of raw materials in one place will also affect the efficiency of stirring and mixing.

[0004] Therefore, an automatic proportioning equipment for inorganic pigment production is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic proportioning equipment for inorganic pigment production, which solves the problems of uneven material falling in the batching barrel resulting in low space utilization rate and unsatisfactory stirring and mixing effect. By means of a shunt component, the distribution position of the material in the batching barrel after falling is changed, and by making the scraping component generate a lateral displacement during rotation, the various areas inside the batching barrel are scraped in all directions while making the shunt component produce a vibration effect.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An automatic proportioning device for inorganic pigment production, comprising a batching barrel, a storage bin, a driving mechanism, a transmission shaft, a turntable and a feed pipe. The driving mechanism is connected below the batching barrel. The transmission shaft is arranged in the batching barrel and connected to the driving mechanism. The turntable is connected to the upper end of the transmission shaft. The storage bin is connected to the turntable. The feed pipe is opened at the lower end of the storage bin and extends into the batching barrel. It further comprises a scraping assembly and a shunting assembly. The scraping assembly is connected to the transmission shaft. The shunting assembly is connected to the transmission shaft and arranged above the scraping assembly. The shunting assembly is located directly below the feed pipe. Raw materials fall from the feed pipe onto the shunting assembly and are evenly distributed in various areas within the batching barrel through the shunting assembly. The transmission shaft drives the scraping assembly to rotate and generate a lateral displacement within the batching barrel, and at the same time, the scraping assembly causes the shunting assembly to vibrate.

[0008] Through the above solution, when the raw materials fall onto the shunting assembly, they will flow along the surface of the shunting assembly and then be evenly scattered at different diameter position areas within the batching barrel. At the same time, the shunting assembly will rotate driven by the transmission shaft, and thus can evenly sprinkle the materials at various positions within the batching barrel. In addition, the scraping assembly rotates with the rotation of the transmission shaft and can scrape and level various materials within the batching barrel. The scraping assembly will have a lateral displacement during the rotation process, so as to scrape the inside of the batching barrel in all directions. At the same time, the shunting assembly will vibrate up and down due to the lateral displacement of the scraping assembly, and thus shake off a large amount of raw materials at the corresponding positions, making the positions where the raw materials fall within the batching barrel more uniform, improving the space utilization rate, and at the same time increasing the scraping and leveling efficiency.

[0009] Preferably, the scraping assembly includes a mounting rod, a compression spring, a top block and a scraping strip. The mounting rod is connected to the transmission shaft, and the end of the mounting rod away from the transmission shaft is inclined towards the rear end in its advancing direction. The compression spring is arranged within the transmission shaft. Since the mounting rod will be subject to the resistance of the materials when rotating, by arranging the mounting rod inclined, the force exerted by the materials on the mounting rod will form a certain angle with the mounting rod at this time, so as to achieve force unloading to a certain extent, and thus reduce the resistance when the mounting rod moves. The scraping strip is arranged below the mounting rod. The scraping strip is in a comb shape and is inclined towards the front end in its moving direction. The scraping strip will rotate with the mounting rod and scrape and mix the raw materials within the batching barrel.

[0010] Preferably, the compression spring is arranged within the transmission shaft, and both ends of the compression spring are respectively connected to the mounting rod and the transmission shaft. A plurality of the top blocks are connected to the batching barrel. The central angle between every two of the top blocks is equal. The end of the top block is spherical, and the length of the top block is equal to the distance between every two scraping strips.

[0011] To avoid excessive resistance when the scraping strip moves, the scraping strip is set in a comb shape, and there is a certain distance between each scraping strip. However, there will be areas that cannot be scraped in this way. Through the above solution, when the installation rod rotates a set angle, it will touch a top block, and then the installation rod will move horizontally in the direction of the transmission shaft under the action of the top block. At the same time, the recovery speed of the compression spring is restricted to a certain extent, so that the installation rod can only return to its original position after rotating the set angle. Furthermore, during the rotation process, multiple scraping strips comprehensively scrape and mix the areas at different diameters in the batching barrel, improving the mixing effect of the materials.

[0012] Preferably, the flow splitting component includes a flow splitting plate, a main flow channel, and flow splitting channels. The flow splitting plate is connected to the transmission shaft and is located above the installation rod. The upper surface of the flow splitting plate is inclined, and its height gradually increases along the direction away from the transmission shaft. The main flow channel is opened on the upper surface of the flow splitting plate, and the highest point of the main flow channel is directly below the feed pipe. A plurality of flow splitting channels are arranged on the flow splitting plate and communicate with the main flow channel.

[0013] Through the above solution, after the raw materials fall from the storage bin, they will directly fall on the main flow channel of the flow splitting plate, then slide down along the main flow channel, and enter the flow splitting channels along the way. Finally, they slide out of the flow splitting channels and fall into the batching barrel, so that the materials can be evenly sprinkled in each area of the batching barrel, improving the space utilization rate and facilitating the scraping strip to mix them, thus improving the work efficiency.

[0014] Preferably, there are a plurality of flow splitting channels. Since the upper surface of the flow splitting plate is an inclined surface, the raw materials will first flow out from the flow splitting channel closest to the feed pipe after falling, and then flow out from the subsequent flow splitting channels in turn. This will cause a large amount of materials to flow out from the flow splitting channel close to the feed pipe, and the amount of materials in the flow splitting channels close to the transmission shaft direction is less, resulting in uneven material distribution. Therefore, the distance value between every two flow splitting channels gradually increases along the direction away from the transmission shaft to ensure that a sufficient amount of materials can slide into the flow splitting channels close to the transmission shaft and ensure the uniformity of the material distribution in the batching barrel.

[0015] Preferably, a plurality of lower convex blocks are provided on the installation rod, and a plurality of upper convex blocks are provided below the flow splitting plate. The upper convex blocks and the lower convex blocks are staggered.

[0016] Through the above solution, the flow splitting plate can slide within a small range on the transmission shaft. Therefore, when the installation rod moves horizontally, the lower convex blocks squeeze the upper convex blocks to lift the flow splitting plate and then let it fall, so that the flow splitting plate vibrates due to its own weight after falling, thereby accelerating the sliding of the raw materials.

[0017] Preferably, the position of the lower convex block corresponds to the position of the scraping strip, and the position of the upper convex block corresponds to the position of the flow splitting channel.

[0018] Through the above solution, when the lower bump collides with the upper bump, the position of the shunt channel exactly corresponds to the position of the scraping bar. After the shunt plate is vibrated, a large amount of materials will be scattered. At this time, the scraping bar is exactly near the position where a large amount of materials fall, and can scrape and level the materials in time, ensuring the working efficiency and mixing effect.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. For the automatic proportioning equipment for inorganic pigment production of the present invention, by setting the main channel and the shunt channel, and opening the shunt channel in the position areas with different diameters in the batching barrel, so that the raw materials can flow out from the shunt channel along the main channel after falling, thereby making the materials evenly scattered at each position in the batching barrel, improving the uniformity of material distribution, avoiding the materials piling up in one place and affecting the mixing efficiency, improving the space utilization rate in the batching barrel, and facilitating the scraping component to mix the materials, thus improving the working efficiency.

[0021] 2. For the automatic proportioning equipment for inorganic pigment production of the present invention, by obliquely arranging the mounting rod and making the mounting direction of the scraping bar correspond to the mounting rod, so that the surface forms a certain inclination angle with the moving direction, thereby reducing the resistance generated by material accumulation during movement, and the comb-shaped scraping bar can scrape the materials in the position areas with different diameters in the batching barrel, and at the same time guide the materials, improving the fluidity of the materials in the batching barrel and enhancing the mixing effect.

[0022] 3. For the automatic proportioning equipment for inorganic pigment production of the present invention, by setting the lower bump and the upper bump, when the mounting rod undergoes a lateral displacement, the lower bump collides with the upper bump to make the shunt plate move up and down to generate vibration, thereby accelerating the sliding of the raw materials. And at this time, the position of the scraping bar corresponds to the position of the shunt channel, so the scraping bar can scrape and stir the materials in time, ensuring the mixing effect and efficiency of the materials.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 7 , the present invention provides an automatic proportioning device for inorganic pigment production, and the technical solutions are as follows:

[0033] Specifically, please refer to Figure 1 and Figure 2, An automatic proportioning device for inorganic pigment production, including a batching barrel 1, a storage bin 2, a driving mechanism 3, a transmission shaft 4, a turntable 5 and a feed pipe 6. The driving mechanism 3 is connected below the batching barrel 1. The driving mechanism 3 can specifically be selected as a servo motor to adjust the rotation speed of the internal mechanism of the batching barrel 1. The transmission shaft 4 is arranged in the batching barrel 1 and is connected to the driving mechanism 3. The turntable 5 is fixed at the upper end of the transmission shaft 4, and the turntable 5 can block the upper opening of the batching barrel 1. The storage bin 2 is fixedly connected to the turntable 5. The feed pipe 6 is opened at the lower end of the storage bin 2 and extends into the batching barrel 1. The storage bin 2 is cylindrical. A screw is arranged inside the feed pipe 6, which can push the material from the storage bin 2 into the batching barrel 1. It also includes a shunting component 8. When the raw material is pushed out from the feed pipe 6, it will fall on the shunting component 8 and then slide along the surface of the shunting component 8, and then evenly scatter in different diameter position areas inside the batching barrel 1. At the same time, the shunting component 8 will rotate driven by the transmission shaft 4, so as to evenly sprinkle the material at various positions inside the batching barrel 1. In addition, it also includes a scraping component 7. The scraping component 7 rotates with the transmission shaft 4 to scrape the material in the batching barrel 1 evenly. At the same time, the scraping component 7 will have a lateral displacement during rotation, so as to scrape the inside of the batching barrel 1 in all directions. In addition, the shunting component 8 will shake up and down due to the lateral displacement of the scraping component 7, and then shake off a large amount of raw materials at the corresponding positions, making the position where the raw materials fall in the batching barrel 1 more uniform, improving the space utilization rate, and at the same time improving the scraping and evenness efficiency.

[0034] As an implementation manner of the present invention, referring to Figure 3 , Figure 4 and Figure 5 , the scraping component 7 is connected to the transmission shaft 4. The scraping component 7 includes a mounting rod 701, a compression spring 702, a top block 703 and a scraping strip 704. The mounting rod 701 is slidably connected to the transmission shaft 4. An arc surface is provided at one end of the mounting rod 701 away from the transmission shaft 4, and the extension line of the length direction of the mounting rod 701 does not intersect with the central axis of the transmission shaft 4, and the inclination direction of the mounting rod 701 is inclined towards the rear of its advancing direction, so as to avoid material accumulation and excessive resistance during rotation, achieve unloading to a certain extent, and then reduce the resistance when the mounting rod 701 moves; the scraping strip 704 is fixedly connected below the mounting rod 701. There are multiple scraping strips 704, and the multiple scraping strips 704 are in a comb shape. The scraping strip 704 is inclined towards the front end of its moving direction. The scraping strip 704 will rotate with the mounting rod 701 to scrape and mix the raw materials in the batching barrel 1, and at the same time can push the material to move, so as to evenly distribute the material in the batching barrel 1, which is convenient for mixing multiple materials;

[0035] After the squeegee strip 704 is set in a comb shape, there will be a certain distance between each squeegee strip 704, which will result in areas that cannot be wiped by the squeegee strip 704. Therefore, a compression spring 702 is provided. The compression spring 702 is arranged inside the transmission shaft 4, and both ends of the compression spring 702 are respectively connected to the mounting rod 701 and the transmission shaft 4. A plurality of the top blocks 703 are connected to the batching barrel 1 to impose a certain limit on the recovery speed of the compression spring 702. Since the angle between every two of the top blocks 703 is 60 degrees, the compression spring 702 is set to be able to recover to its original position only after the mounting rod 701 rotates 60 degrees. At this time, after the mounting rod 701 is reset, it can touch the next top block 703, and then the lateral displacement action is carried out in a cycle, that is, the mounting rod 701 will perform a lateral displacement in the direction of the transmission shaft 4 under the action of the top block 703. Also, because the mounting rod 701 is always rotating with the transmission shaft 4, the movement paths of a plurality of squeegee strips 704 can comprehensively cover the space inside the batching barrel 1, thereby ensuring the mixing effect of the materials; the end of the top block 703 is spherical, and the length of the top block 703 is equal to the distance between every two squeegee strips 704.

[0036] As an implementation manner of the present invention, referring to Figure 2 、 Figure 5 、 Figure 6 and Figure 7, the shunt assembly 8 includes a shunt plate 801, a main runner 802 and shunt runners 803. The shunt plate 801 is disposed above the mounting rod 701. The shunt plate 801 is slidably connected to the transmission shaft 4, that is, the shunt plate 801 can slide up and down along the transmission shaft 4. The upper surface of the shunt plate 801 is inclined, and its height gradually increases along the direction away from the transmission shaft 4, so that the material can slide from the high point to the low point of the shunt plate 801, and then the material can be sprinkled on various areas of the batching barrel 1. The main runner 802 is opened on the upper surface of the shunt plate 801, and the highest point of the main runner 802 is directly below the feed pipe 6. After the raw material falls from the storage bin 2, it will directly fall on the main runner 802 of the shunt plate 801. A plurality of the shunt runners 803 are disposed on the shunt plate 801 and communicate with the main runner 802. The material in the main runner 802 slides down along the inclined surface and then enters the shunt runners 803 along the way, and finally slides into the batching barrel 1 from the shunt runners 803, so that the material can be evenly sprinkled on various areas in the batching barrel 1, improving the space utilization rate and facilitating the squeegee 704 to mix it, improving the work efficiency; a plurality of the shunt runners 803 are provided. Since the upper surface of the shunt plate 801 is an inclined surface, the raw material will first flow out from the shunt runner 803 closest to the feed pipe 6 after falling, and then flow out from the subsequent shunt runners 803 in turn. This will cause a large amount of material to flow out from the shunt runner 803 close to the feed pipe 6, and the amount of material in the shunt runner 803 close to the transmission shaft 4 is less, resulting in uneven material distribution. Therefore, the distance value between every two shunt runners 803 is gradually increased along the direction away from the transmission shaft 4 to ensure that a sufficient amount of material can slide into the shunt runner 803 close to the transmission shaft 4 and ensure the uniformity of the material distribution in the batching barrel 1.

[0037] As an embodiment of the present invention, referring to Figure 4 and Figure 6 , a plurality of lower bumps 9 are provided on the mounting rod 701, and a plurality of upper bumps 10 are provided below the shunt plate 801. The upper bumps 10 and the lower bumps 9 are staggered. When the mounting rod 701 moves horizontally, the upper bumps 10 are pushed up and then dropped by the lower bumps 9, so that the shunt plate 801 vibrates after falling due to its own weight, thereby accelerating the sliding of the raw material. The cross sections of the upper bumps 10 and the lower bumps 9 are both semicircular, which can make the staggered displacement of the two more smooth; the position of the lower bumps 9 corresponds to the position of the squeegee 704, and the position of the upper bumps 10 corresponds to the position of the shunt runner 803. When the lower bumps 9 collide with the upper bumps 10, the position of the shunt runner 803 just corresponds to the position of the squeegee 704, which can enable the squeegee 704 to evenly scrape the large amount of material spilled from the shunt runner 803 in time, ensuring the work efficiency and the mixing effect.

[0038] The specific working principle is as follows: First, different colored mineral raw materials required are respectively added into their respective storage bins 2. Then, the driving mechanism 3 is started, and the turntable 5 is driven to rotate through the transmission shaft 4. Since the storage bin 2 is fixed on the turntable 5, the storage bin 2 will also rotate with the turntable 5. During the feeding process, the materials will be scattered along the circumference of the batching barrel 1, thereby improving the space utilization rate of the batching barrel 1. At the same time, it can prevent powdery materials from piling up together and reducing the stirring and mixing efficiency.

[0039] Since the position of the feed pipe 6 is fixed, this results in a fixed diameter of the circumferential area where the materials fall into the batching barrel 1. And the feed pipe 6 is usually arranged in the edge area of the batching barrel 1. Therefore, the materials will concentrate in the edge area of the batching barrel 1. To further improve the space utilization rate of the batching barrel 1 when the materials are falling, a flow splitting component 8 is provided. Since one end of the main flow channel 802 is arranged directly below the feed pipe 6, when the materials fall into the batching barrel 1 along the feed pipe 6, they will first fall into the main flow channel 802 of the flow splitting plate 801. Also, because the flow splitting plate 801 is inclined, and the height is lower closer to the central area of the batching barrel 1, the materials in the main flow channel 802 will flow along the inclined surface of the flow splitting plate 801 towards the central area of the batching barrel 1. And there are multiple flow splitting channels 803 communicated with the main flow channel 802 on the flow splitting plate 801. The flow splitting channels 803 are inclined towards the rear end in the advancing direction of the flow splitting plate 801, which can accelerate the falling speed of the materials.

[0040] In addition, since the raw materials will first flow out from the flow splitting channels 803 closest to the feed pipe 6, in order to ensure that there is also enough material flowing out from the flow splitting channels 803 far from the feed pipe 6, the interval distance between every two flow splitting channels 803 is changed, that is, the interval between every two flow splitting channels 803 closer to the feed pipe 6 is longer, to ensure that a sufficient amount of material slides into the flow splitting channels 803 close to the transmission shaft 4, ensuring the uniformity of the material distribution in the batching barrel 1 and facilitating the subsequent stirring and mixing operation of various materials.

[0041] In order to achieve the mixing operation of materials, an installation rod 701 and multiple scraping bars 704 are provided. The multiple scraping bars 704 are in a comb shape, which can reduce the resistance during movement, and scrape and mix the materials following the rotation of the transmission shaft 4, and push the materials to move, so that various materials are fully mixed in the batching barrel 1. However, after the scraping bars 704 are set in a comb shape, there will be a certain distance between each scraping bar 704, which will result in areas that cannot be scraped by the scraping bars 704. To avoid this situation, the installation rod 701 is set to a structure that can move horizontally, that is, the installation rod 701 is pushed to move by the top block 703, and then the installation rod 701 is controlled to reset by the compression spring 702. By setting the angle between every two top blocks 703 to sixty degrees, the installation rod 701 will contact the top block 703 every time it rotates sixty degrees to generate a horizontal displacement. At the same time, the reset speed of the compression spring 702 is restricted so that it returns to its original position after the installation rod 701 rotates sixty degrees. At this time, the installation rod 701 can touch the next top block 703 after reset, and then repeat the horizontal displacement action. The one-way distance of the horizontal displacement of the installation rod 701 is the same as the distance between every two scraping bars 704. That is to say, during the reset process of the installation rod 701, the multiple scraping bars 704 can cover the positions of all diameter annular regions in the batching barrel 1, thus ensuring the scraping and mixing effect of the materials in the batching barrel 1.

[0042] When the installation rod 701 makes a horizontal displacement, the lower convex block 9 at its upper end will collide with the upper convex block 10 below the flow dividing plate 801, and then push the flow dividing plate 801 to move upward along the transmission shaft 4. When the lower convex block 9 separates from the upper convex block 10, the flow dividing plate 801 will fall under its own gravity and the gravity of the materials, thereby generating a certain vibration, so as to shake off more materials. Also, because the position of the lower convex block 9 corresponds to the position of the scraping bar 704, and at the same time the position of the upper convex block 10 corresponds to the position of the flow dividing channel 803, when the lower convex block 9 collides with the upper convex block 10 and more materials are shaken off from the flow dividing channel 803, the falling position of the materials exactly corresponds to the position of the scraping bar 704. Therefore, the scraping bar 704 can timely scrape and even the large amount of spilled materials, which not only ensures the mixing effect but also ensures the working efficiency during the mixing of various raw materials.
