Description

Technical Field

[0001] The present application relates to the technical field of epoxy powder coating production and processing equipment, and in particular to a highly permeability-resistant epoxy powder coating production and processing device. Background Art

[0002] High anti-penetration epoxy powder coating is a coating with excellent anti-penetration properties. It is widely used in pipeline anti-corrosion (such as anti-corrosion of the inner and outer walls of oil and gas pipelines), metal structure anti-corrosion (such as anti-corrosion coating of metal structures such as bridges and towers), automotive parts (such as coating of automobile chassis, wheels and other parts) and ship anti-corrosion (such as anti-corrosion coating of ships). The coating is mainly composed of epoxy resin, color filler, additives and curing agent.

[0003] The production and processing of the epoxy powder coating includes the steps of raw material premixing, melt extrusion, tableting and grinding. That is, through these steps, the components are uniformly mixed and extruded into sheets or granules, and then ground to obtain the desired powder coating.

[0004] However, due to the large difference in the proportion of raw materials of high permeability resistance epoxy powder coatings, such as the required amount of epoxy resin is large, the required amount of color filler is large, and the required amount of additives and curing agents is small or even very small. In the production of existing epoxy powder coatings, these raw materials are premixed first. Due to the large difference in the proportion of each raw material and the fact that the main raw material is solid raw material, the premixed raw materials require more time to stir and mix, and are difficult to mix evenly. The performance of high permeability resistance epoxy powder coatings depends to a large extent on the uniformity of its composition. If the raw materials are not mixed evenly, the various properties of the coating, such as permeability resistance, adhesion, scratch resistance and corrosion resistance, may be affected, resulting in a decrease in the overall performance of the coating. Summary of the invention

[0005] The present application proposes a highly permeability-resistant epoxy powder coating production and processing device, which has the advantage that the coating can be mixed evenly before the melt extrusion stage. It is used to solve the problem that when existing coating processing equipment and process steps are used to produce and process highly permeability-resistant epoxy powder coatings, the difference in the proportion of each raw material is too large, and the main raw material is a solid raw material, which makes it difficult to mix the raw materials evenly before the extrusion stage.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a highly permeability-resistant epoxy powder coating production and processing device, comprising a barrel, a transmission pipe is provided in the middle of the inner cavity of the barrel, a spiral blade is fixedly installed on the outer side of the transmission pipe, and the transmission pipe is driven to rotate by a feeding motor, a material mixing barrel is fixedly installed at one end of the barrel, and a plurality of heaters are fixedly installed on the outer sides of the barrel and the material mixing barrel, a discharging barrel is fixedly installed at one end of the discharging barrel, a module is fixedly installed in the middle of one end of the discharging barrel, a discharging trough is opened in the middle of the module, and at least three feeding barrels are also fixedly installed on the barrel, and a flow valve is provided at the connection between the feeding barrel and the barrel.

[0007] The interior of the mixing barrel is provided with two stirring devices which are symmetrical up and down. The interior of the mixing barrel is also provided with two positioning support devices. One positioning support device includes a first circular ring and a second circular ring which are arranged inside and outside. Two partitions are movably mounted on the two circular rings. The two partitions are arranged on both sides of the stirring device. The interior of the mixing barrel is provided with baffles which are located on both sides of the partition. Through grooves are opened on the two baffles. The through grooves on the two baffles are arranged up and down respectively. The two baffles are driven to rotate synchronously by a servo motor which is arranged on the side of the barrel away from the mixing barrel.

[0008] Furthermore, the barrel is fixedly mounted on two first support plates, the two first support plates are fixedly mounted on the base, one end of the transmission tube extends out of the outside of one of the first support plates and is fixedly mounted with a passive gear, a second support plate located on one side of the passive gear is fixedly mounted on the top of the base, a feeding motor is fixedly mounted on the second support plate, a driving gear is fixedly mounted on the output shaft of the feeding motor, and the outer teeth of the driving gear are meshed with the outer teeth of the passive gear.

[0009] Furthermore, one of the stirring devices includes a stirring motor fixedly mounted on the middle of the outer side of the mixing barrel, the output shaft of the stirring motor extends to the inner wall of the mixing barrel and is fixedly mounted with a positioning sleeve, and a plurality of stirring shafts are fixedly mounted on the outer side of the positioning sleeve.

[0010] Furthermore, the stirring shafts are arranged in an equidistant spiral array on the positioning sleeve, which is conducive to more uniform stirring of the molten raw materials.

[0011] Further, the positioning support device includes two groups of first positioning blocks, and the number of each group of first positioning blocks is two. One group of first positioning blocks is respectively fixedly installed at the bottom and top of the inner cavity of the material mixing barrel, one end of each group of first positioning blocks away from the material mixing barrel is respectively fixedly connected with a positioning coupling shaft, and one end of the two positioning coupling shafts away from the first positioning block is respectively fixedly connected with a second positioning block. The two second positioning blocks in the two positioning support devices are both fixedly installed on the outside of the positioning transverse tube, and the positioning transverse tube is arranged in the middle of the inner cavity of the material mixing barrel, two symmetrically arranged first semicircular support shafts are fixedly installed between the two first positioning blocks, and the two first semicircular support shafts are spliced ​​into a first circular ring, and the center of the first circular ring is the same as the center of the positioning transverse tube, and two partitions are respectively arranged on both sides of the positioning coupling shaft.

[0012] Furthermore, the outer sides of the two partitions are movably fitted with the inner wall of the material mixing barrel, the inner sides of the two partitions are movably fitted with the outer side of the positioning cross tube, and the two ends of the partitions are movably fitted with one side of the two baffles respectively, so that the two partitions and the two baffles can divide the material mixing barrel into two chambers, so that the feed amount of one of the chambers can be increased to squeeze out the molten raw material in the other chamber.

[0013] Furthermore, the length of the stirring shaft increases evenly from close to the positioning transverse tube to far away from the positioning transverse tube. Under the premise that the two baffles do not contact the stirring shaft, the length of the stirring shaft is set to the longest state as much as possible, thereby improving the stirring effect.

[0014] Furthermore, the two baffles are fixedly connected by a linkage rod, and the linkage rod is arranged inside the positioning cross tube. One end of the linkage rod is fixedly connected to a transmission rod, and one end of the transmission rod extends from the inside of the transmission tube and is fixedly connected to the output shaft of the servo motor. The transmission rod is directly driven by the servo motor to drive the two baffles to rotate, thereby changing the upper and lower positions of the through grooves on the two baffles, so as to change the chamber into which the molten raw material in the barrel enters.

[0015] Furthermore, a bearing is provided between the linkage rod and the positioning transverse tube, and high temperature resistant sealing rings are provided at the joints between the two ends of the positioning transverse tube and the two baffles to prevent molten raw materials from entering the positioning transverse tube.

[0016] Furthermore, the shape of the through groove is fan-shaped, and under the condition that the two partitions and the baffle separate the inner cavity of the material mixing barrel into two chambers, the flow rate of the through groove can be made large enough by opening the corresponding fan-shaped groove according to the position of the partition and the setting of the circular baffle.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present application provides a highly permeability-resistant epoxy powder coating production and processing device, which provides a mixing barrel between a discharge barrel and a machine barrel, wherein the inner cavity of the mixing barrel is provided with two rotatable baffles and two partitions rotating along two circular rings, so as to divide the inner cavity of the mixing barrel into a first chamber and a second chamber, and the two chambers are controlled to communicate with the inner cavities of the machine barrel and the discharge barrel respectively by driving the rotation of the baffles, thereby utilizing the pressure of the feeding material to increase the amount of molten raw material in one of the chambers, and to press out the molten raw material in the other chamber, and stirring is performed by stirring devices arranged in the two chambers. Compared with the existing equipment and premixing methods, the raw materials can be stirred and mixed more evenly in a molten state, thereby improving the production and processing quality of the highly permeability-resistant epoxy powder coating and ensuring the high permeability resistance of the epoxy powder coating.

[0019] 2. Two partitions are movably mounted on two rings, and the pressure of the feeding is used to move the partitions along the rings to change the amount of molten raw materials in the two chambers. The amount of molten raw materials in one chamber is increased to squeeze out the molten raw materials in the other chamber. Compared with directly setting a stirring device in the barrel, the raw materials entering the two chambers have more time to be stirred, which is conducive to more uniform mixing of the raw materials, thereby further improving the production and processing quality of high anti-permeability epoxy powder coatings.

[0034] See also Figure 2-Figure 6 Two stirring devices 14 are symmetrically arranged on the upper and lower sides of the mixing barrel 4. One stirring device 14 includes a stirring motor 141 fixedly installed in the middle of the outer side of the mixing barrel 4. The output shaft of the stirring motor 141 extends to the inner wall of the mixing barrel 4 and is fixedly installed with a positioning sleeve 142. A plurality of stirring shafts 143 are fixedly installed on the outer side of the positioning sleeve 142. The number of stirring shafts 143 is not less than three, and the stirring shafts 143 are distributed on the positioning sleeve 142 in an equidistant spiral array. The output shaft is driven by the stirring motor 141 to drive the positioning sleeve 142 to rotate, and the molten raw materials in the mixing barrel 4 are stirred by the plurality of stirring shafts 143 on the positioning sleeve 142, so that the molten epoxy powder coating raw materials are evenly mixed.

[0035] The interior of the material mixing barrel 4 is also provided with two positioning support devices 15, please refer to Figure 4-Figure 6The positioning support device 15 includes two groups of first positioning blocks 151, and the number of each group of first positioning blocks 151 is two. Each group of first positioning blocks 151 is fixedly installed at the bottom and the top of the inner cavity of the material mixing barrel 4. One end of each group of first positioning blocks 151 away from the material mixing barrel 4 is fixedly connected to a positioning shaft 152. One end of the two positioning shafts 152 away from the first positioning blocks 151 is fixedly connected to a second positioning block 153. The two second positioning blocks 153 in the two positioning support devices 15 are fixedly installed on the positioning transverse tube 154. On the outside, the positioning transverse tube 154 is arranged in the middle of the inner cavity of the material mixing barrel 4, and two symmetrically arranged first semicircular support shafts 155 are fixedly installed between the two first positioning blocks 151, and the two first semicircular support shafts 155 are spliced ​​into a first circular ring, and the center of the first circular ring is the same as the center of the positioning transverse tube 154, and two symmetrically arranged second semicircular support shafts 156 are fixedly installed between the two second positioning blocks 153, and the two second semicircular support shafts 156 are spliced ​​into a second circular ring, and the center of the second circular ring is the same as the center of the positioning transverse tube 154.

[0036] Two partitions 16 are movably mounted on the first and second circular rings, and the two partitions 16 are respectively arranged on both sides of the positioning coupling 152, and the outer sides of the two partitions 16 are movably fitted with the inner wall of the material mixing barrel 4, and the inner sides of the two partitions 16 are movably fitted with the outer sides of the positioning transverse tube 154, and baffles 17 are movably arranged on both sides of the positioning transverse tube 154, and through grooves 171 are provided on the two baffles 17, and the through grooves 171 on the two baffles 17 are divided into upper and lower arrangements, that is, the through groove 171 on the left baffle 17 in the material mixing barrel 4 is arranged at the bottom, and the through groove 171 on the right baffle 17 in the material mixing barrel 4 is arranged at the top, and the two ends of the partition 16 are respectively movably fitted with one side of the two baffles 17, and the two first and second circular rings arranged inside and outside facilitate the two partitions 16 to stably rotate and move along the circular rings.

[0037] The chamber between the two baffles 17 in the inner cavity of the material mixing barrel 4 is divided into two chambers by two partitions 16, namely, a first chamber and a second chamber, and when the first chamber is communicated with the through groove 171 on one of the baffles 17, the second chamber is communicated with the through groove 171 on the other baffle 17. The two partitions 16 are movably arranged on the first ring and the second ring. After the molten raw material in the barrel 3 enters the first chamber through the through groove 171 on one of the baffles 17, the amount of molten raw material in the first chamber increases, which will cause the two partitions 16 to rotate and compress the second chamber. The molten raw material in the second chamber flows into the discharge barrel 5 through the through groove 171 on the other baffle 17. The two stirring devices stir in the first chamber and the second chamber respectively, so that the molten raw materials in the two chambers are stirred evenly when they flow into the discharge barrel 5, thereby ensuring that the extruded raw materials are mixed evenly, and avoiding the problem of uneven mixing of raw materials affecting the production and processing quality of epoxy powder coatings.

[0038] The length of the stirring shaft 143 increases evenly from close to the positioning transverse tube 154 to far away from the positioning transverse tube 154 , and the limiting blocking effect of the second positioning block 153 on the partition 16 can prevent the partition 16 from rotating to contact the stirring device.

[0039] The two baffles 17 are fixedly connected by a linkage rod 18, which is arranged inside the positioning transverse tube 154, and a bearing is arranged between the linkage rod 18 and the positioning transverse tube 154, so that the linkage rod 18 can rotate relative to the positioning transverse tube 154. The two ends of the positioning transverse tube 154 are respectively provided with high-temperature resistant sealing rings at the joints with the two baffles 17 to prevent the molten raw materials from entering the positioning transverse tube 154. One end of the linkage rod 18 is fixedly connected to a transmission rod 19. Please continue to refer to Figure 1-Figure 2 , Figure 4-Figure 5 One end of the transmission rod 19 extends from the inside of the transmission tube 8 to one side of the passive gear 10. A servo motor 20 located above the feeding motor 12 is fixedly mounted on the second support plate 11, and the output shaft of the servo motor 20 is fixedly connected to one end of the transmission rod 19. The servo motor 20 drives the transmission rod 19 to drive the rotating linkage rod 18 to rotate, thereby driving the two baffles 17 to rotate, and then swapping the upper and lower positions of the through grooves 171 on the two baffles 17, that is, controlling the two baffles 17 to rotate half a circle, from the state where the first chamber is connected to the inner cavity of the barrel 3 to the state where the first chamber is connected to the inner cavity of the discharge barrel 5, and from the state where the second chamber is connected to the inner cavity of the discharge barrel 5 to the state where the second chamber is connected to the inner cavity of the barrel 3.

[0040] See also Figure 3 and Figure 7 The through groove 171 is fan-shaped. Under the condition that the two partitions 16 and the baffle 17 separate the inner cavity of the material mixing barrel 4 into two chambers, the fan-shaped groove is opened so that the flow rate of the through groove 171 is large enough.

[0041] A high temperature resistant sealing ring is provided between the transmission rod 19 and the transmission tube 8 near the baffle 17 to prevent the molten raw material in the barrel 3 from entering the interior of the transmission tube 8 .

[0042] Please continue reading Figure 1-Figure 2 A plurality of equally spaced feeding barrels 21 are fixedly mounted on the barrel 3, the number of the feeding barrels 21 is not less than three, and a flow valve 22 is provided at the connection between the feeding barrel 21 and the barrel 3. The flow valve 22 can adjust the flow rate of the raw materials inside the feeding barrel 21 entering the barrel 3, thereby controlling the proportion of the mixed raw materials.

[0043] When in use, a small amount or trace amount of compatible raw materials are pre-mixed in advance and added to a feeding barrel 21, a raw material with a high proportion, such as epoxy resin as a base resin, is added separately to a feeding barrel 21, and then a raw material with a relatively large proportion, such as an auxiliary resin, is added separately to a feeding barrel 21, and then the flow valve 22 on each feeding barrel 21 is adjusted according to the proportion of the raw materials to control the flow rate of the raw materials in each feeding barrel 21 into the barrel 3, and at the same time, the feeding motor 12 is started to drive the transmission pipe 8 to drive the spiral blade 9 to rotate, so that the raw materials in the barrel 3 flow to the first chamber in the material mixing barrel 4 through the through groove 171 on the baffle 17 away from the end of the discharge barrel 5, and at the same time, the stirring motor 141 is started to drive the positioning sleeve 142 to rotate, and the molten raw materials are stirred by the stirring shaft 143, so that the raw materials are evenly mixed in the molten state, such as Figure 8 As shown, the amount of molten raw material in the first chamber increases, which will drive the two partitions 16 to rotate, compressing the space in the second chamber, so that the molten raw material in the second chamber enters the discharge barrel 5 through the through groove 171 on the other baffle 17, and is squeezed out by the discharge groove 601, which is convenient for subsequent compaction and grinding work. During the period when the amount of molten raw material in the first chamber increases, the stirring motor 141 located above the material mixing barrel 4 will drive the positioning sleeve 142 in the first chamber to drive the stirring shaft 143 to rotate, and stir the molten raw material in real time. When the partition 16 is close to the second positioning block 153, that is, Fig. 9 As shown, the servo motor 20 is started again to drive the transmission rod 19 to drive the two baffles 17 to rotate half a circle, so that the molten raw material of the barrel 3 enters the second chamber first, thereby increasing the amount of molten raw material in the second chamber, compressing the internal space of the first chamber, and pressing the molten raw material in the first chamber into the discharge barrel 5. This reciprocating process can ensure that the molten raw material entering the mixing barrel 4 is evenly mixed and then squeezed out, thereby ensuring the production and processing quality of high anti-permeability epoxy powder coatings.

[0044] Regarding starting the servo motor 20 to drive the two baffles 17 to rotate half a circle, the amount of raw material extruded can be controlled according to time, that is, when the flow rate of the molten raw material extruded through the discharge chute 601 remains unchanged, the molten raw material enters the first chamber, so that the two baffles 16 are moved from Figure 8 Move above as shown Fig. 9 As shown below, the required time is to control the servo motor 20 to start the two baffles 17 to rotate half a circle.

[0045] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
