Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic core production, and in particular to a magnetic core spraying house and a magnetic core insulation layer spraying production line. BACKGROUND

[0002] A magnetic core is a material with magnetic properties, widely used in the coils and transformers of various electronic devices. In order to improve its voltage resistance and performance stability, it is usually necessary to spray powder on its surface to form an insulation layer. However, the existing annular magnetic core spraying equipment has many problems in actual application.

[0003] For example, Chinese patent CN115502017A discloses an annular magnetic core insulation layer spraying production line and a spraying method for the annular magnetic core insulation layer. The production line includes a tunnel furnace, a rotating workbench, a powder spraying house and a powder recovery house, and realizes the preheating, spraying and drying and curing processes of the annular magnetic core through automatic equipment. Although this production line improves the spraying efficiency to some extent, when spraying in the powder spraying house, the tray carrying the magnetic core will also be sprayed, causing the powder to adhere to the tray, not only causing waste of the powder, but also increasing the loss of the tray and reducing the service life of the equipment.

[0004] In order to solve the above problems, reference is made to the drawings Figure 1 , the drawings Figure 2 , the applicant proposes an improved magnetic core insulation layer spraying device. The device directly inserts the carrying grooves 210 of the carrying table 20 and the powder spraying table 200 through the multiple supporting plates 11 arranged on the magnetic core carrying mechanism 10, thereby realizing direct carrying of the magnetic core and avoiding the use of trays. However, although this design reduces the use of trays, due to the presence of the carrying grooves 210, the powder is easy to enter and deposit in the carrying grooves 210 when spraying, thereby affecting the normal entry or disengagement of the magnetic core carrying mechanism 10 from the carrying grooves 210, and further reducing the operation efficiency and reliability of the equipment. SUMMARY

[0005] The purpose of the present application is to provide a magnetic core spraying house and a magnetic core insulation layer spraying production line, which effectively solves the problem of powder deposition by optimizing the design of the carrying groove and adding a powder spraying partition plate and other structures.

[0006] In a first aspect, the present application provides a magnetic core spraying house, comprising: a spraying machine box provided with a working cavity and a feeding port, the feeding port being communicated with the working cavity to allow a magnetic core carrying mechanism to enter or disengage from the working cavity; a powder spraying table arranged in the working cavity, the powder spraying table being used to carry the magnetic core, the powder spraying table being provided with multiple spaced carrying grooves; A powder spraying gun is movably arranged above the powder spraying table, and the powder spraying gun is used for spraying powder on the magnetic core on the powder spraying table. A lifting mechanism is arranged below the powder spraying table, and the lifting mechanism is provided with a plurality of powder spraying partitions arranged at intervals, the plurality of powder spraying partitions are arranged in the plurality of conveying grooves in a lifting manner, and the lifting mechanism can drive the powder spraying partitions to ascend to abut against the magnetic core on the powder spraying table to block the powder sprayed by the powder spraying gun from entering the conveying grooves; and the powder spraying partitions can also descend to enable the magnetic core conveying mechanism to be inserted into the conveying grooves to place or pick up the magnetic core on the powder spraying table.

[0007] The magnetic core spraying house provided by the application can effectively block the powder sprayed by the powder spraying gun from entering the conveying grooves by arranging the lifting mechanism and the powder spraying partitions below the powder spraying table. This solves the problem that the powder is easy to enter the conveying grooves and deposit in the prior art, avoids the interference of the powder accumulated in the conveying grooves on the magnetic core conveying mechanism, and improves the operation efficiency and reliability of the equipment. Meanwhile, the powder spraying partitions provide sufficient space for the magnetic core conveying mechanism when descending, so that the magnetic core conveying mechanism can be smoothly inserted into the conveying grooves to place or pick up the magnetic core. This design protects the conveying mechanism from being polluted by the powder and prolongs the service life of the conveying mechanism. In addition, the powder spraying partitions not only effectively block the powder from entering the conveying grooves during the spraying process, but also support the magnetic core, so as to ensure that the magnetic core remains stable during the spraying process, avoid uneven spraying caused by the shaking or displacement of the magnetic core, and help to improve the uniformity of the coating on the surface of the magnetic core, thereby improving the voltage resistance and performance stability of the magnetic core.

[0008] Further, the lifting mechanism comprises a connecting rod, a driving assembly and a driven assembly, the plurality of powder spraying partitions are each provided with a connecting hole on a side away from the powder spraying gun, the connecting rod can sequentially pass through the connecting holes of the plurality of powder spraying partitions, the driven assembly is connected to the output end of the driving assembly and the connecting rod, and the driving assembly can drive the connecting rod to ascend or descend through the driven assembly.

[0009] By adopting the above technical solution, the connecting rod sequentially passes through the connecting holes of the plurality of powder spraying partitions, so as to ensure that all the powder spraying partitions can ascend and descend synchronously. This design ensures the consistency of the powder spraying partitions during the ascending or descending process, and avoids the problems of uneven spraying or blocking of the conveying grooves caused by the uncoordinated movement of individual partitions.

[0010] Further, the driven assembly comprises a driven rod and fixing plates, the driven rod is arranged below the powder spraying partitions, the number of the fixing plates is two, the two fixing plates are arranged on opposite sides of the powder spraying partitions respectively, and first fixing holes and second fixing holes are arranged on the two fixing plates respectively, the first fixing holes are used for fixing the opposite ends of the connecting rods, and the second fixing holes are used for fixing the driven rod, and the driving assembly drives the connecting rods to ascend or descend through the driven rod.

[0011] According to the technical scheme, the driven rod is arranged below the powder spraying partitions, the two fixing plates are arranged on opposite sides of the powder spraying partitions respectively, the first fixing holes and the second fixing holes arranged on the fixing plates are used for fixing the connecting rods and the driven rod respectively, and the connecting rods, the fixing plates and the driven rod are connected as a whole, so that the connection stability between the components is further enhanced, and the whole lifting mechanism can run stably during the working process.

[0012] Further, the driven assembly further comprises a first connecting plate, the number of the driven rods is at least two, and the at least two driven rods are arranged through the first connecting plate, and the output end of the driving assembly drives the driven rods to ascend or descend through the first connecting plate.

[0013] According to the technical scheme, the number of the driven rods is at least two, and the at least two driven rods are arranged through the first connecting plate. Through the combination of the multiple driven rods and the first connecting plate, the support strength of the driven assembly is significantly enhanced, so that the connecting rods can bear greater force during the lifting process and are prevented from being bent or deformed.

[0014] Further, the driving assembly comprises a driving cylinder and a driving rod, the driving rod is arranged in the driving cylinder in a liftable manner, the number of the first connecting plates is two, a fixing rod is arranged between the two first connecting plates, a connecting sleeve hole is arranged on one end of the driving rod which faces the fixing rod, and the fixing rod is arranged through the connecting sleeve hole.

[0015] According to the technical scheme, one end of the driving rod which faces the fixing rod is provided with the connecting sleeve hole, the number of the first connecting plates is two, the fixing rod is arranged between the two first connecting plates, and the fixing rod is arranged through the connecting sleeve hole. Through the cooperation of the connecting sleeve hole and the fixing rod, the connection between the driving rod and the driven assembly is firm and reliable.

[0016] Further, the driven assembly further comprises a second connecting plate, a buffer rod and a buffer cylinder, the at least two driven rods are arranged through the second connecting plate, the buffer cylinder is fixedly arranged below the second connecting plate, the buffer rod is arranged in the buffer cylinder, and the second connecting plate can abut against the buffer rod when the driven rods descend.

[0017] The combination of the buffer cylinder and the buffer rod can effectively reduce the impact force between the driven rod and the buffer rod during the rapid descent process. This buffering effect not only protects the buffer rod and the driven rod, but also reduces the impact on the entire device. By reducing the impact and vibration, the buffering mechanism significantly improves the service life of the device and reduces the maintenance cost of the device.

[0018] Further, the first translation mechanism is provided on the spraying machine box, the spraying machine box is provided with a moving hole communicating with the working cavity, the connecting plate is movably arranged in the moving hole, and the opposite ends of the connecting plate are connected with the first translation mechanism and the second translation mechanism respectively. The moving direction of the second translation mechanism is perpendicular to the moving direction of the first translation mechanism, and the powder spraying gun is arranged on the second translation mechanism. The first translation mechanism and the second translation mechanism can drive the powder spraying gun to move above the powder spraying table.

[0019] By arranging the first translation mechanism outside the working cavity and connecting the second translation mechanism through the connecting plate and the moving hole, the volume of the working cavity is significantly reduced, which means that the diffusion range of the powder in the working cavity is smaller, and the waste of powder is reduced. This not only improves the spraying efficiency, but also reduces the production cost.

[0020] Further, the working cavity comprises a powder spraying cavity and an avoiding cavity which are communicated with each other, the powder spraying table is arranged in the powder spraying cavity, and the powder spraying gun can move to the powder spraying cavity to spray the magnetic core on the powder spraying table, and the powder spraying gun can also move to the avoiding cavity to avoid the magnetic core conveying mechanism.

[0021] By the above technical scheme, the powder spraying gun can spray the magnetic core in the powder spraying cavity, and space is left for the magnetic core conveying mechanism in the avoiding cavity. When the powder spraying gun is in the avoiding cavity, it does not interfere with the normal operation of the magnetic core conveying mechanism, thereby improving the overall operation efficiency of the device.

[0022] Further, the end of the powder spraying partition plate facing the powder spraying gun is provided with an abutting end portion, and the extension width of the abutting end portion is arranged in a decreasing manner from away from the powder spraying gun to close to the powder spraying gun.

[0023] By designing the extension width of the abutting end portion in a decreasing manner, the contact area between the powder spraying partition plate and the magnetic core is significantly reduced, which means that the amount of powder adhered to the back of the magnetic core is greatly reduced, thereby avoiding the problem of uneven coating caused by powder adhesion, thereby improving the spraying quality after the magnetic core is turned over.

[0024] In a second aspect, the present application provides a magnetic core insulation layer spraying production line, comprising: The magnetic core spraying house of any of the above; A preheating box; A curing box; A conveying belt sequentially arranged in the preheating box and the curing box, and capable of driving the magnetic core to sequentially pass through the preheating box and the curing box; A magnetic core conveying mechanism arranged between the preheating box and the curing box, capable of conveying the magnetic core on the conveying belt passing through the preheating box to the powder spraying table for spraying, and conveying the magnetic core on the powder spraying table completing spraying to the conveying belt for conveying the magnetic core to the curing box.

[0025] As can be seen from the above, the magnetic core spraying house provided by the present application sets the lifting mechanism and the powder spraying partition plate below the powder spraying table, and the powder spraying partition plate can be lifted to abut against the magnetic core during spraying, effectively blocking the powder sprayed by the powder spraying gun from entering the conveying groove. This solves the problem that the powder in the prior art easily enters the conveying groove and deposits, avoids the interference of the powder accumulation in the conveying groove on the magnetic core conveying mechanism, and improves the operation efficiency and reliability of the equipment. At the same time, the powder spraying partition plate provides sufficient space for the magnetic core conveying mechanism when it is lowered, so that the magnetic core conveying mechanism can be smoothly inserted into the conveying groove to place or pick up the magnetic core. This design protects the conveying mechanism from being contaminated by the powder, prolongs the service life of the conveying mechanism. In addition, the powder spraying partition plate not only effectively blocks the powder from entering the conveying groove during spraying, but also supports the magnetic core, thereby ensuring that the magnetic core remains stable during spraying, avoiding uneven spraying caused by the shaking or displacement of the magnetic core, and helping to improve the uniformity of the coating on the surface of the magnetic core, thereby improving the voltage resistance and performance stability of the magnetic core.

DETAILED DESCRIPTION

[0036] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0037] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0038] The magnetic core spraying house disclosed in the application is mainly applied to the insulation layer spraying of annular magnetic cores, and effectively solves the powder deposition problem through the optimization of the design of the carrying groove and the increase of the powder spraying partition plate and other structures.

[0039] Reference is made to the accompanying drawings Figure 3 , the accompanying drawings Figure 4 In one embodiment, the magnetic core spraying house comprises a spraying machine box 100, a powder spraying table 200, a powder spraying gun 300, and a lifting mechanism 400. The spraying machine box 100 is provided with a working cavity 110 and a feeding port 120, and the feeding port 120 is communicated with the working cavity 110 to allow the magnetic core carrying mechanism 10 to enter or leave the working cavity 110. The powder spraying table 200 is arranged in the working cavity 110, and is used to carry the magnetic core. The powder spraying table 200 is provided with a plurality of carrying grooves 210 arranged at intervals. The powder spraying gun 300 is movably arranged above the powder spraying table 200, and is used to spray powder on the magnetic core on the powder spraying table 200. The lifting mechanism 400 is arranged below the powder spraying table 200, and is provided with a plurality of powder spraying partition plates 410 arranged at intervals. The plurality of powder spraying partition plates 410 are liftably arranged in the plurality of carrying grooves 210. The lifting mechanism 400 can drive the powder spraying partition plates 410 to ascend to abut against the magnetic core on the powder spraying table 200, so as to block the powder sprayed by the powder spraying gun 300 from entering the carrying grooves 210. The powder spraying partition plates 410 can also be lowered to allow the magnetic core carrying mechanism 10 to insert into the carrying grooves 210, so as to place or pick up the magnetic core on the powder spraying table 200.

[0040] From the above, the magnetic core spraying room provided by the application can effectively block the powder sprayed by the powder spraying gun 300 from entering the conveying groove 210 by setting the lifting mechanism 400 and the powder spraying baffle 410 below the powder spraying table 200, and the powder spraying baffle 410 can be lifted to abut against the magnetic core during the spraying process. This solves the problem that the powder is easy to enter the conveying groove 210 and deposit in the prior art, avoids the interference of the powder accumulation in the conveying groove 210 on the magnetic core conveying mechanism 10, and improves the operation efficiency and reliability of the equipment. At the same time, the powder spraying baffle 410 provides sufficient space for the magnetic core conveying mechanism 10 when it is lowered, so that the magnetic core conveying mechanism 10 can be smoothly inserted into the conveying groove 210 to place or pick up the magnetic core. This design protects the conveying mechanism from powder pollution and prolongs the service life of the conveying mechanism. In addition, the powder spraying baffle 410 not only effectively blocks the powder from entering the conveying groove 210 during the spraying process, but also supports the magnetic core, thereby ensuring that the magnetic core remains stable during the spraying process, avoiding uneven spraying caused by the shaking or displacement of the magnetic core, and helping to improve the uniformity of the coating on the surface of the magnetic core, thereby improving the voltage resistance and performance stability of the magnetic core.

[0041] In one of the embodiments, the working cavity 110 includes a powder spraying cavity 111 and an avoiding cavity 112 which are in communication with each other, the powder spraying cavity 111 is provided with the powder spraying table 200, the powder spraying gun 300 can be moved to the powder spraying cavity 111 to spray powder on the magnetic core on the powder spraying table 200, and the powder spraying gun 300 can also be moved to the avoiding cavity 112 to avoid the magnetic core conveying mechanism 10.

[0042] By adopting the above technical scheme, the powder spraying gun 300 can spray the magnetic core in the powder spraying cavity 111, and the space is left for the magnetic core conveying mechanism 10 in the avoiding cavity 112. When the powder spraying gun 300 is in the avoiding cavity 112, it will not interfere with the normal operation of the magnetic core conveying mechanism 10, thereby improving the overall operation efficiency of the equipment.

[0043] In one of the embodiments, the lower part of the spraying machine box 100 is provided with a recycling hopper 140 which communicates with the working cavity 110, the recycling hopper 140 is connected with a cyclone separation mechanism 142 (as shown in the accompanying drawings) through a recycling pipeline 141, and the cyclone separation mechanism 142 can extract the powder in the working cavity 110 through the recycling pipeline 141. Figure 1

[0044] By adopting the above technical scheme, the excess powder generated during the spraying process can be effectively recycled through the recycling hopper 140 and the cyclone separation mechanism 142, thereby reducing the waste of powder. This not only improves the utilization rate of materials, but also reduces the production cost.

[0045] ​Since the number of powder spraying partitions 410 needed is multiple, the lifting mechanism 400 in the prior art cannot guarantee the synchronous lifting of multiple powder spraying partitions 410. Due to the high independence of the movement of each powder spraying partition 410, the lifting speed of some partitions is inconsistent, resulting in a height difference between the powder spraying partitions 410. This asynchronous phenomenon can cause the conveying groove 210 to be unable to be completely closed or completely opened, thereby affecting the spraying effect, and even can cause the powder to enter the conveying groove 210, affecting the normal operation of the magnetic core conveying mechanism 10.

[0046] For this purpose, reference is made to the accompanying drawings Figure 5 In one embodiment, the lifting mechanism 400 includes a connecting rod 420, a driving assembly 430, and a driven assembly 440. The multiple powder spraying partitions 410 are provided with connecting holes on the side away from the powder spraying gun 300. The connecting rod 420 can pass through the connecting holes of the multiple powder spraying partitions 410 in sequence. The driven assembly 440 is connected to the output end of the driving assembly 430 and the connecting rod 420, respectively. The driving assembly 430 can drive the connecting rod 420 to rise or fall through the driven assembly 440.

[0047] Specifically, the number of connecting rods 420 can be adjusted as needed, for example, the number of connecting rods 420 can be two, three, etc. It can be understood that the number of connecting holes corresponds to the number of connecting rods 420. All connecting rods 420 can pass through the corresponding connecting holes, thereby enhancing the stability of the overall structure.

[0048] With the above technical solution, the connecting rod 420 passes through the connecting holes of the multiple powder spraying partitions 410 in sequence, ensuring that all powder spraying partitions 410 can be lifted synchronously. This design ensures the consistency of the powder spraying partitions 410 during the lifting or lowering process, avoiding the problem of uneven spraying or blocking of the conveying groove 210 caused by the uncoordinated movement of individual partitions.

[0049] For this purpose, reference is made to the accompanying drawings Figure 5 In one embodiment, the end of the powder spraying partition 410 towards the powder spraying gun 300 is provided with an abutting end portion 411. The extension width of the abutting end portion 411 decreases from away from the powder spraying gun 300 to close to the powder spraying gun 300.

[0050] With the above technical solution, by designing the extension width of the abutting end portion 411 to be in a decreasing form, the contact area between the powder spraying partition 410 and the magnetic core is significantly reduced. A smaller contact area means that the amount of powder adhered to the back of the magnetic core is greatly reduced, avoiding the problem of uneven coating caused by powder adhesion, thereby improving the spraying quality after the magnetic core is turned over.

[0051] For this purpose, reference is made to the accompanying drawings Figure 6In one of the embodiments, the driven assembly 440 includes a driven rod 441 and two fixed plates 442. The driven rod 441 is arranged below the plurality of powder spraying partitions 410. The two fixed plates 442 are arranged on opposite sides of the plurality of powder spraying partitions 410. The two fixed plates 442 are respectively provided with a first fixed hole and a second fixed hole. The first fixed hole is used for fixing the opposite ends of the connecting rod 420. The second fixed hole is used for fixing the driven rod 441. The driving assembly 430 drives the connecting rod 420 to rise or fall through the driven rod 441.

[0052] Specifically, the number of the driven rod 441 can be adjusted as needed. For example, the number of the connecting rod 420 can be two or three. The opposite ends of all the driven rods 441 are fixed on the two fixed plates 442 through the second fixed hole, thereby enhancing the stability of the overall structure.

[0053] According to the above technical solution, the driven rod 441 is arranged below the powder spraying partition 410. The two fixed plates 442 are arranged on opposite sides of the powder spraying partition 410. The first fixed hole and the second fixed hole arranged on the fixed plate 442 are respectively used for fixing the connecting rod 420 and the driven rod 441. The plurality of connecting rods 420, the fixed plate 442 and the driven rod 441 are connected as a whole. This design further enhances the connection stability between the components and ensures that the entire lifting mechanism 400 can run smoothly during operation.

[0054] Although the driven rod 441 is arranged in the above embodiment, a single driven rod 441 may not be able to provide sufficient support strength, especially when the plurality of powder spraying partitions 410 are simultaneously lifted. The connecting rod 420 and the driven rod 441 may bear a large force. If the strength of the driven rod 441 is insufficient, it may be bent or deformed during lifting, affecting the synchronous lifting of the powder spraying partition 410.

[0055] Therefore, in one of the embodiments, the driven assembly 440 further includes a first connecting cross plate 443. The number of the driven rod 441 is at least two. The at least two driven rods 441 are arranged through the first connecting cross plate 443. The output end of the driving assembly 430 drives the driven rod 441 to rise or fall through the first connecting cross plate 443.

[0056] According to the above technical solution, the number of the driven rod 441 is at least two. The at least two driven rods 441 are arranged through the first connecting cross plate 443. This design significantly enhances the support strength of the driven assembly 440 through the combination of the plurality of driven rods 441 and the first connecting cross plate 443, ensuring that the connecting rod 420 can bear a larger force during lifting and avoiding bending or deformation.

[0057] In one of the embodiments, the driving assembly 430 comprises a driving cylinder 431 and a driving rod 432, the driving rod 432 is arranged in the driving cylinder 431 in a lifting manner, the number of the first connecting plates 443 is two, and a fixing rod 444 is arranged between the two first connecting plates 443, one end of the driving rod 432 towards the fixing rod 444 is provided with a connecting sleeve hole, and the fixing rod 444 penetrates through the connecting sleeve hole.

[0058] According to the above technical scheme, one end of the driving rod 432 towards the fixing rod 444 is provided with a connecting sleeve hole, the number of the first connecting plates 443 is two, and a fixing rod 444 is arranged between the two first connecting plates 443, and the fixing rod 444 penetrates through the connecting sleeve hole. Through the cooperation of the connecting sleeve hole and the fixing rod 444, the connection between the driving rod 432 and the driven assembly 440 is firm and reliable.

[0059] In one of the embodiments, the driven assembly 440 further comprises a second connecting plate 445, a buffer rod 446 and a buffer cylinder 447, at least two driven rods 441 penetrate through the second connecting plate 445, the buffer cylinder 447 is fixedly arranged below the second connecting plate 445, the buffer rod 446 is arranged in the buffer cylinder 447, and the second connecting plate 445 can abut against the buffer rod 446 when the driven rod 441 is lowered.

[0060] Specifically, the buffer cylinder 447 can be a rubber buffer cylinder, which uses the elasticity of rubber material to absorb impact. This way is convenient to obtain materials, cheap and easy to maintain and replace, but the buffering effect is not obvious in high-precision and high-speed response occasions. The buffer cylinder 447 can also be a hydraulic buffer cylinder, which uses the flowability and incompressibility of hydraulic fluid to achieve buffering.

[0061] According to the above technical scheme, the combination of the buffer cylinder 447 and the buffer rod 446 can effectively reduce the impact force between the driven rod 441 and the buffer rod 446 during rapid descent. This buffering effect not only protects the buffer rod 446 and the driven rod 441, but also reduces the impact on the entire device. By reducing the impact and vibration, the buffering mechanism significantly improves the service life of the device and reduces the maintenance cost of the device.

[0062] Reference is made to the accompanying drawings Figure 7In one of the embodiments, the first translation mechanism 500, the second translation mechanism 600 and the connecting plate 700 are further included, the first translation mechanism 500 is arranged on the spraying machine box 100, the spraying machine box 100 is provided with a moving hole 130 communicating with the working cavity 110, the connecting plate 700 is movably arranged in the moving hole 130, and the opposite ends of the connecting plate 700 are connected with the first translation mechanism 500 and the second translation mechanism 600 respectively, the moving direction of the second translation mechanism 600 is perpendicular to the moving direction of the first translation mechanism 500, and the powder spraying gun 300 is arranged on the second translation mechanism 600, so that the first translation mechanism 500 and the second translation mechanism 600 can drive the powder spraying gun 300 to move above the powder spraying table 200.

[0063] Specifically, referring to the accompanying drawings Figure 8 The first translation mechanism 500 and the second translation mechanism 600 both include a translation motor 610, a lead screw 620 and a mounting plate 630, the output end of the translation motor 610 is connected with the lead screw 620, the mounting plate 630 is threadedly connected with the lead screw 620, when the translation motor 610 drives the lead screw 620 to rotate, the mounting plate 630 can move on the lead screw 620, and by arranging the connecting plate 700 and the powder spraying gun 300 on the mounting plate 630, the movement of the powder spraying gun 300 on the powder spraying table 200 is realized.

[0064] By arranging the first translation mechanism 500 outside the working cavity 110 and connecting the connecting plate 700 and the moving hole 130 with the second translation mechanism 600, the volume of the working cavity 110 is significantly reduced, and the smaller volume of the working cavity 110 means that the diffusion range of the powder in the working cavity 110 is smaller, and the waste of the powder is reduced.
