Description

Technical Field

[0001] This invention relates to the field of magnetic powder core processing technology, and in particular to a spraying system for a coating machine. Background Technology

[0002] Magnetic powder cores are a type of ring-shaped material made by mixing and pressing ferromagnetic powder particles with an insulating medium.

[0003] During the processing of magnetic powder cores, various auxiliary materials need to be mixed into the raw materials of the magnetic powder cores. These auxiliary materials include powdered auxiliary materials and liquid auxiliary materials. In order to ensure that the various auxiliary materials are evenly mixed in the raw materials, a coating machine is usually used. The powdered auxiliary materials and liquid auxiliary materials are evenly mixed in the raw materials through the stirring blades in the coating machine and the spraying device set in the coating machine. The existing spraying device includes a nozzle set in the cover of the coating machine, which connects the inlet of the nozzle to the external liquid auxiliary materials. The liquid auxiliary materials are sprayed onto the raw materials being stirred through the nozzle.

[0004] However, when spraying liquid additives, the spraying range of the nozzle is limited and fixed, and it cannot be adjusted in real time according to the stirring direction of the raw materials. As a result, the liquid additives need to take a period of time to be fully mixed with all the raw materials, which leads to uneven mixing of the raw materials and liquid additives. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a spraying system for a coating machine to solve the technical problem of uneven mixing of raw materials and liquid additives caused by the limited and fixed spraying range of the existing method of spraying liquid additives with nozzles in the background art, which cannot be adjusted in real time according to the stirring direction of the raw materials.

[0006] According to an embodiment of the present invention, a spraying system for a coating machine is installed on the coating machine and is used to spray raw materials stored in the coating machine. The coating machine includes a rotating shaft, and the spraying system includes spraying equipment, supporting equipment, and intermittent equipment.

[0007] The support equipment includes a first box and a second box that are rotatably connected to each other. The rotating shaft passes through the first box and the second box. One of the first box and the second box is connected to the cover of the coating machine to support the intermittent equipment. The other of the first box and the second box is used to support the spraying equipment.

[0008] The intermittent device includes at least one first transmission member disposed on the rotating shaft and a plurality of second transmission members that are mutually connected. At least two of the plurality of second transmission members are respectively connected to the first transmission member and the second housing, so that when the rotating shaft rotates, the first transmission member drives the plurality of second transmission members to mutually transmit according to the movement of the rotating shaft, so as to make the second housing rotate.

[0009] The number of transmission parts on the first transmission member is less than the number of transmission parts on a second transmission member that is close to the first transmission member, so that the spraying device on the second housing performs intermittent motion in the same direction according to the rotating shaft.

[0010] Furthermore, the intermittent device includes a second first transmission component and a second second transmission component that are mutually connected.

[0011] One of the second first transmission component and the second second transmission component is rotatably connected to the first housing, and the other is connected to the second housing;

[0012] The number of transmission parts on the first transmission member is less than the number of transmission parts on the second transmission member.

[0013] Furthermore, the second transmission component is rotatably connected to the first housing, and the second transmission component is fixedly connected to the second housing;

[0014] Both the middle part of the second transmission component and the middle part of the second housing have openings for the rotating shaft to pass through.

[0015] Furthermore, the second housing includes a shell and a water storage cover, one side of which is fixedly connected to the inner wall of the shell to form a storage space for liquid storage between the water storage cover and the shell;

[0016] The storage space has a size that gradually decreases from one end near the housing to the other, and an opening is formed at the top of the storage space for connecting the second transmission component to the housing.

[0017] Furthermore, the spraying device includes a spraying disc that communicates with the storage space, and a pipe body;

[0018] One end of the tube is inserted through the support device and used to transport liquid auxiliary materials, and the other end is used to overlap the opening in the storage space. The extension direction of the opening is consistent with the rotation direction of the second box, so that when the second box drives the water storage cover to rotate, the end of the tube near the water storage cover continues to overlap the opening.

[0019] Furthermore, multiple spray discs are provided, and the multiple spray discs are spaced apart at the bottom of the second housing;

[0020] In this configuration, each of the multiple spraying discs is arranged opposite to the other.

[0021] Furthermore, the spraying equipment also includes multiple valves, with one valve located between the inlet of the spraying disc and the water storage hood, for controlling the speed at which the liquid medium in the water storage hood flows to the spraying disc.

[0022] Furthermore, the spraying disc includes a disc body and a plurality of drainage holes disposed on the disc body, the plurality of drainage holes being evenly distributed on the surface of the disc body.

[0023] Furthermore, the coating machine includes a material bucket and a lid;

[0024] The rotating shaft is rotatably connected to the cover, and multiple sets of rotating rollers are spaced apart along the axial direction of the rotating shaft.

[0025] Furthermore, each group of rotating rollers includes multiple rotating rollers, and all of the multiple rotating rollers are fixedly connected to the rotating shaft.

[0026] The spacing between any two adjacent rotating rollers is smaller than the thickness of the magnetic powder core.

[0027] Compared with the prior art: In the spraying system of the coating machine proposed in this invention, the number of transmission parts on the first transmission member is less than the number of transmission parts on a second transmission member close to the first transmission member. That is, when the rotating shaft rotates, the first transmission member rotates along with the rotating shaft, and the second transmission member connected to the first transmission member performs transmission. Then, the force is transmitted through other second transmission members, thereby realizing the rotation of the second box. The spraying equipment arranged on the second box rotates intermittently in sync with the rotation of the rotating roller, thereby realizing the intermittent rotation of the spraying equipment according to the rotation shaft. Compared with the traditional method of spraying liquid auxiliary materials with nozzles, the spraying system in this embodiment makes the sprayed liquid auxiliary materials move along with the rotation of the rotating roller, thereby adjusting in real time according to the stirring direction of the raw materials, thus ensuring uniform mixing of the raw materials and liquid auxiliary materials.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] Please see Figures 1-6 The image shows a spraying system 200 of a coating machine 100 in the first embodiment of the present invention. The coating machine 100 includes a rotating shaft 110.

[0041] It should be noted that in some preferred embodiments, the coating machine 100 may also include a material bucket 120 and a cover 130. The material bucket 120 is used to carry the raw materials of the magnetic powder core and some powder auxiliary materials. In order to facilitate the full mixing of the raw materials and auxiliary materials, in this embodiment, the rotating shaft 110 is rotatably connected to the cover 130, and multiple sets of rotating rollers 140 are arranged at intervals along the axial direction of the rotating shaft 110.

[0042] Specifically, each set of rotating rollers 140 includes multiple rotating rollers 140, all of which are fixedly connected to the rotating shaft 110. After the raw materials and auxiliary materials are completely put into the material container 120, the cover 130 and the material container 120 are closed and connected. By rotating the rotating shaft 110, the multiple rotating rollers 140 move to fully mix the raw materials and powdered auxiliary materials in the material container 120. It should be noted that, in order to facilitate the rotation of the rotating shaft 110, in some preferred embodiments, the coating machine 100 may also include a drive motor, which is arranged on the top of the cover 130, and the output shaft of the drive motor can be connected to the end of the rotating shaft 110 to drive the rotating shaft 110 to rotate, thereby completing the step of mixing the raw materials and auxiliary materials.

[0043] However, during the raw material processing of magnetic powder cores, liquid auxiliary materials need to be added. In the spray system 200 of this embodiment, the spray system 200 is installed on the coating machine 100 and is used to spray the raw materials stored in the coating machine 100. The spray system 200 includes a spray device 210, a support device 220 and an intermittent device 230.

[0044] Specifically, the support device 220 includes a first housing 221 and a second housing 222 that are rotatably connected to each other. A rotating shaft 110 passes through the first housing 221 and the second housing 222. One of the first housing 221 and the second housing 222 is connected to the cover 130 of the coating machine 100 to support the intermittent equipment 230. The other of the first housing 221 and the second housing 222 is used to support the spraying equipment 210.

[0045] It should be noted that in some preferred embodiments, the first housing 221 can be fixedly connected to the cover 130, and the second housing 222 can be rotatably connected to the first housing 221. It should be noted that, in order to ensure the stability of the rotatable connection, a sliding groove and a sliding block can be arranged on the opposite surfaces of the first housing 221 and the second housing 222, respectively. The sliding groove can be arranged on the first housing 221 or on the second housing 222. It should be noted that, when the sliding groove is arranged on the first housing 221, a sliding block is arranged on the second housing 222. Through the cooperation between the sliding block and the sliding groove, the second housing 222 can be rotatably connected to the bottom of the first housing 221.

[0046] In some preferred embodiments, multiple sliders can be arranged, and the multiple sliders can be distributed at intervals on the second housing 222.

[0047] In addition, the intermittent device 230 includes at least one first transmission member 231 disposed on the rotating shaft 110 and a plurality of second transmission members 232 that are mutually connected. At least two of the plurality of second transmission members 232 are respectively connected to the first transmission member 231 and the second housing 222 so that when the rotating shaft 110 rotates, the first transmission member 231 drives the plurality of second transmission members 232 to mutually drive each other according to the movement of the rotating shaft 110, so that the second housing 222 rotates.

[0048] The number of transmission parts on the first transmission member 231 is less than the number of transmission parts on a second transmission member 232 that is close to the first transmission member 231, so that the spraying device 210 on the second housing 222 performs intermittent motion in the same direction according to the rotating shaft 110.

[0049] In some preferred embodiments, the first transmission member 231 can be an irregular bevel gear, that is, a portion of the bevel gear's circumferential surface is arranged with teeth. These teeth can occupy a portion of the bevel gear's circumferential surface area, which can be 1 / 3, 1 / 4, or 1 / 5, without special description. The first transmission member 231 can be sleeved on the rotating shaft 110. When the rotating shaft 110 rotates, the first transmission member 231 rotates along with the rotating shaft 110. A second transmission member 232, which is connected to the first transmission member 231, then transmits the force through other second transmission members 232, thereby causing the second housing 222 to rotate. The spraying device 210 arranged on the second housing 222 then rotates synchronously with the rotation of the rotating roller 140. The rotation is achieved by rotating the second housing 222. However, since the number of transmission parts on the first transmission member 231 is less than the number of transmission parts on the second transmission member 232, after the first transmission member 231 rotates for the first revolution, the second transmission member 232 rotates a portion. After the first transmission member 231 rotates for the second revolution, the second transmission member 232 rotates a portion again, and so on, thereby realizing the intermittent rotation of the second housing 222. Through the rotation of the second housing 222, the intermittent rotation of the spraying device 210 according to the rotating shaft 110 is completed. Compared with the traditional method of spraying liquid auxiliary materials with nozzles, the spraying system 200 in this embodiment makes the sprayed liquid auxiliary materials move with the rotation of the rotating roller 140, thereby adjusting in real time according to the stirring direction of the raw materials, so as to ensure that the raw materials and liquid auxiliary materials are mixed evenly.

[0050] It should be noted that in some preferred embodiments, the movement distance of the spraying device 210 can be determined by adjusting the area of ​​the transmission part on the circumferential surface of the first transmission member 231. When the area of ​​the transmission part on the circumferential surface of the first transmission member 231 is small, the movement distance of the spraying device 210 is small; when the area of ​​the transmission part on the circumferential surface of the first transmission member 231 is large, the movement distance of the spraying device 210 is large. This will not be specifically explained here. In addition, it should be noted that the second transmission member 232 adopts a bevel gear with teeth evenly distributed on its circumferential surface, and the transmission part can be a toothed gear.

[0051] Specifically, it should be noted that the intermittent device 230 includes a second transmission component 2321 and a second transmission component 2322 that are connected to each other. One of the second transmission component 2321 and the second transmission component 2322 is rotatably connected to the first housing 221, and the other is connected to the second housing 222.

[0052] In this embodiment, the number of transmission parts on the first transmission member 231 is less than the number of transmission parts on the second transmission member 2321. It should be noted that the second transmission member 2321 and the second transmission member 2322 are the same as the number of second transmission members 232. However, in this embodiment, the second transmission member 2321 and the second transmission member 2322 are not limited to the number of second transmission members 232. They can also be three, four, five, etc., which will not be specifically explained here.

[0053] In some preferred embodiments, the second transmission member 2321 is rotatably connected to the first housing 221, and the second transmission member 2322 is fixedly connected to the second housing 222;

[0054] The second transmission component 2322 and the second housing 222 are both provided with openings for the rotating shaft 110 to pass through.

[0055] Furthermore, the second housing 222 includes a shell 2221 and a water storage cover 2222. One side of the water storage cover 2222 is fixedly connected to the inner wall of the shell 2221 to form a storage space 2223 for liquid storage between the water storage cover 2222 and the shell 2221.

[0056] The storage space 2223 has a space size that gradually decreases from one end near the housing 2221 to the other end, and an opening 2224 is formed on the top of the storage space 2223 for connecting the second transmission member 2322 to the housing 2221.

[0057] It should be noted that in this embodiment, the spatial dimensions of the storage space 2223 gradually decrease from one end near the shell 2221 to the other end, thereby forming a conical structure that is wide at the bottom and narrow at the top. When the liquid excipient is in the storage space 2223, the special shape of the storage space 2223 can be used to prevent the liquid excipient from flowing out of the storage space 2223 when the second box 222 is rotating, thereby ensuring the safety performance of the liquid excipient.

[0058] Furthermore, the spraying device 210 includes a spraying disc 211 that is interconnected with the storage space 2223, and a pipe body 212;

[0059] One end of the pipe 212 is fitted with a support device 220 and used to transport liquid auxiliary materials. The other end is used to overlap the opening 2224 in the storage space 2223. The extension direction of the opening 2224 is consistent with the rotation direction of the second box 222, so that when the second box 222 drives the water storage cover 2222 to rotate, the end of the pipe 212 near the water storage cover 2222 continues to overlap the opening 2224. It should be noted that the extension direction of the opening 2224 makes the water storage cover 2222 have a frustum structure. That is, when one end of the pipe 212 overlaps the opening 2224 on the water storage cover 2222, the water storage cover... As the second housing 222 rotates, the end of the tube 212 that overlaps the opening 2224 will not contact the edge of the opening 2224, thus avoiding the movement of the tube 212 due to the movement of the water storage cover 2222, which would cause instability when transmitting liquid auxiliary materials. It should be noted that the opening 2224 is circular, and the intermittent movement of the second housing 222 will drive the water storage cover 2222 to rotate. By limiting the shape of the water storage cover 2222, the centrifugal force is prevented from causing water to be thrown out of the storage space 2223 of the water storage cover 2222 during the rotation.

[0060] Furthermore, multiple spray discs 211 are provided, and the multiple spray discs 211 are spaced apart at the bottom of the second housing 222;

[0061] Among them, each of the multiple spraying discs 211 has one spraying disc 211 arranged opposite to each other.

[0062] Furthermore, the spraying equipment 210 also includes multiple valves 213. A valve 213 is provided between the inlet of the spraying disc 211 and the water storage hood 2222 to control the speed at which the liquid medium in the water storage hood 2222 flows to the spraying disc 211.

[0063] By utilizing valve 213 and multiple spray discs 211, the flow rate and volume of liquid auxiliary materials can be adjusted in real time according to the state of raw materials and auxiliary materials. This allows for adjustment based on actual conditions. It should be noted that in practice, the flow rate and volume of liquid auxiliary materials need to be adjusted in real time based on the total amount of raw materials and powdered auxiliary materials. When the total amount is low, the total amount of liquid auxiliary materials sprayed by spray disc 211 can be controlled by controlling one valve 213. When one valve 213 reaches the threshold but cannot guarantee the flow rate of liquid auxiliary materials, two or more valves 213 can be activated to control two or more spray discs 211 to output liquid auxiliary materials, thereby ensuring the practicality of the spray system 200 in this embodiment.

[0064] Furthermore, the spraying disc 211 includes a disc body 2111 and a plurality of drainage holes 2112 provided on the disc body 2111, with the plurality of drainage holes 2112 evenly distributed on the surface of the disc body 2111.

[0065] It should be noted that a PLC controller can be added to this system to ensure the intelligent operation of the entire system.

[0066] In summary, the spraying system 200 of the coating machine 100 provided in this embodiment has a smaller number of transmission parts on the first transmission member 231 than on the second transmission member 232 located near the first transmission member 231. That is, when the rotating shaft 110 rotates, the first transmission member 231 rotates along with the rotating shaft 110. The second transmission member 232 connected to the first transmission member 231 then transmits power, and the force is transmitted through other second transmission members 232, thereby causing the second housing 222 to rotate. The spraying device 210 arranged on the second housing 222 then rotates intermittently in sync with the rotation of the rotating roller 140, thus achieving intermittent rotation of the spraying device 210 according to the rotation of the rotating shaft 110. Compared with the traditional method of spraying liquid auxiliary materials with nozzles, the spraying system 200 in this embodiment allows the sprayed liquid auxiliary materials to move along with the rotation of the rotating roller 140, thereby adjusting in real time according to the stirring direction of the raw materials, thus ensuring uniform mixing of the raw materials and liquid auxiliary materials.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
