Description

Technical Field

[0001] The present application relates to the technical field of powder coating production equipment, and in particular to a powder coating feeding device. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigments, fillers and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.

[0003] When processing powder coatings, the powder coatings need to be transported, so a powder coating feeder is used to transport the powder coatings; when feeding, some powder coatings have some agglomeration during the storage process. If the powder coatings are directly fed, the agglomerated powder coatings are not easy to remove in the subsequent process, so they need to be screened out during feeding; Chinese patent "CN213444341U" discloses a "powder coating feeder", which first screens the powder coatings by setting a cleaning filter plate, and the powder coatings of suitable particle size leak through the filter plate to enter the next moving process, while the block-shaped powder coatings remain above the filter plate, and are further scraped off the cleaning filter plate by a cleaning scraper, and finally the powder coatings are screened during feeding to ensure the quality of the powder coatings fed subsequently. Further analysis revealed that in actual applications, there are the following problems: first, the powder coatings remaining on the cleaning filter plate are not just lumps of powder coatings. There are still some qualified powder coatings that cannot pass through the filter holes on the cleaning filter plate well, and only rely on gravity to fall naturally or the push of the cleaning scraper. The leakage efficiency of the coating powder is low, which ultimately affects the feeding efficiency. Utility Model Content

[0004] The purpose of this application is to provide a powder coating feeding device to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a powder coating feeding device, comprising a feeding box, wherein a feeding port is formed at the upper end of the feeding box;

[0006] A filter plate assembly, comprising a filter plate body and a reciprocating drive module, wherein the filter plate body is slidably disposed in the feed box along a first direction and has a plurality of filter holes formed along a thickness direction, and the reciprocating drive module is disposed on the feed box and is suitable for driving the filter plate body to reciprocate along the first direction;

[0007] Discharging assembly, the discharging assembly includes a discharging module and a first driving member for driving the discharging module to move in the second direction. A first through groove is formed in the feeding box in the orientation of the second direction, and a sealing plate is rotatably provided on the same side. The sealing plate is adapted to block the first through groove. The discharging assembly is adapted to discharge the powder remaining on the filter plate body in the second direction through the first through groove;

[0008] Wherein, the first direction is perpendicular to the second direction;

[0009] In the above implementation process, the staff pours the powder coating to be fed into the feeding box from the feeding port. It will first pass through the filter plate body. Multiple filter holes are formed on the filter plate body. The qualified powder coating will pass through the filter holes and further pass through the filter plate body for the next feeding step. The unqualified powder coating in the form of blocks will be blocked by the filter plate body on the filter plate body and cannot enter the next step. At this time, the blocky powder coating can be screened out. At this time, the first driving member drives the discharging module to move in the second direction. The staff opens the sealing plate to connect the first through groove. The discharging module can act on the residual material remaining on the filter plate body and discharge it through the first through groove; In addition, during the feeding and screening process, the reciprocating driving module drives the filter plate body to reciprocate in the first direction. During the reciprocating movement, due to the inertial effect, it will promote the qualified powder coating to quickly pass through the filter holes, thereby improving the feeding efficiency. Further, it will reduce the probability of qualified powder coating remaining on the filter plate body, thereby reducing the waste of raw materials.

[0010] Preferably, the reciprocating driving module includes a connecting block, a cross link, a mounting plate, a first rotary driving member, a rotating shaft and a limiting roller; A longitudinal waist-shaped hole is formed on the longitudinal rod of the cross link. One end of the rotating shaft is connected to the driving end of the first rotary driving member, and the other end is provided with a convex column, which is limited in the longitudinal waist-shaped hole; The first rotary driving member and the limiting roller are arranged on the mounting plate, and the mounting plate is arranged on the feeding box; A plurality of limiting rollers are arranged in an up-and-down distribution and limit the transverse rod of the cross link to drive the cross link to move transversely. The connecting block is connected to the cross link, and the filter plate body is connected to the connecting block;

[0011] In the above implementation process, the first rotary driving member drives the rotating shaft to rotate. The convex column is arranged at the end of the rotating shaft and thus rotates together with the rotating shaft. The convex column is limited in the longitudinal waist-shaped hole of the cross link. The transverse rod of the cross link is limited by the limiting roller (the limiting roller can also be replaced by a slide rail limiting method) and can only move transversely. Thus, driven by the rotating convex column and the longitudinal waist-shaped hole, the cross link will show a transverse reciprocating movement, which can drive the connecting block to reciprocate transversely. The connecting block is connected to the filter plate body, thereby realizing the transverse reciprocating movement of the filter plate body.

[0012] Preferably, the filter plate body is detachably connected to the connecting block;

[0013] In the above implementation process, the filter plate body and the connecting block are detachably connected, so that it is convenient for subsequent regular cleaning to avoid the blockage of some filter holes due to long-term use, which affects the normal feeding efficiency; further, it can be understood that it can be disassembled and installed through the first through groove, that is, the first through groove not only serves as the discharge port for the residual material, but also provides space for the disassembly and installation of the filter plate body.

[0014] Preferably, a T-shaped groove is formed on the connecting block, and a T-shaped block adapted to the T-shaped groove is formed on one side of the filter plate body;

[0015] In the above implementation process, the connecting block and the filter plate body are detachably connected by means of plug-in connection, that is, the T-shaped block of the filter plate body is aligned with the T-shaped groove on the connecting block and inserted, so as to realize the quick connection of the two; it can be understood that the extending direction of the T-shaped groove is the second direction.

[0016] Preferably, the first driving member includes a lead screw and a rotating motor; the rotating motor is arranged in the feeding box, the lead screw penetrates through the discharging module and is in threaded cooperation with the discharging module; the axial direction of the lead screw is parallel to the second direction;

[0017] In the above implementation process, the rotating motor drives the lead screw to rotate, and the lead screw is in threaded cooperation with the discharging module, so as to drive the discharging module to move along the axial direction of the lead screw, that is, move along the second direction.

[0018] Preferably, the discharging module includes a fixing plate, a scraping plate rotatably arranged on the fixing plate and a second rotating driving member arranged in the fixing plate;

[0019] A receiving space is formed in the fixing plate, the second rotating driving member is arranged in the receiving space and its driving end is connected to the scraping plate;

[0020] A threaded hole in threaded cooperation with the lead screw is formed on the fixing plate;

[0021] In the above implementation process, during discharging, it can be understood that the scraping plate abuts against the surface of the filter plate body. As the scraping plate moves along the second direction, it can export the residual materials from the first through groove. When the scraping plate resets, the second rotary driving member can drive the scraping plate to rotate by a certain angle, so that the scraping plate does not abut against the filter plate body. Until it moves in place, the second rotary driving member drives the scraping plate to rotate again to make it abut against the filter plate body, avoiding further accumulation of some powder coatings on the outermost side when the scraping plate resets. In addition, when the reciprocating driving module drives the filter plate body to reciprocate, the second rotary driving member can also drive the scraping plate away from the surface of the filter plate body, so that there is no relative friction and the wear between the two is reduced.

[0022] Preferably, a limiting hole is further provided on the fixing plate, and a limiting rod is provided in the feeding box. The limiting rod is adapted to pass through the limiting hole and its two ends are fixedly arranged on the inner wall of the feeding box.

[0023] In the above implementation process, the cooperation between the limiting rod and the limiting hole on the fixing plate can limit the movement of the fixing plate, so that the discharging module can stably move along the second direction.

[0024] Compared with the prior art, the beneficial effect of the present application is that: this solution uses the reciprocating driving module to drive the filter plate body to reciprocate along the first direction. During the reciprocating movement, due to the inertial effect, it will promote the qualified powder coatings to quickly pass through the filtering holes, thereby improving the feeding efficiency. Moreover, further, it will reduce the probability of qualified powder coatings remaining on the filter plate body, thereby reducing the waste of raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to further understand the utility model content, characteristics and effects of the present application, the following embodiments are cited and described in detail with the accompanying drawings as follows:

[0037] Embodiment

[0038] When processing powder coatings, the powder coatings need to be transported, so a powder coating feeder is used to transport the powder coatings; when feeding, some powder coatings have some agglomeration during the storage process. If the powder coatings are directly fed, the agglomerated powder coatings are not easy to remove in the subsequent process, so they need to be screened out during feeding; Chinese patent "CN213444341U" discloses a "powder coating feeder", which first screens the powder coatings by setting a cleaning filter plate, and the powder coatings of suitable particle size leak through the filter plate to enter the next moving process, while the block-shaped powder coatings remain above the filter plate, and are further scraped off the cleaning filter plate by a cleaning scraper, and finally the powder coatings are screened during feeding to ensure the quality of the powder coatings fed subsequently. Further analysis revealed that in practical applications, there are the following problems: first, the powder coatings remaining on the cleaning filter plate are not only lumps of powder coatings, but also some qualified powder coatings that cannot pass through the filter holes on the cleaning filter plate well, and only rely on gravity to fall naturally or the push of the cleaning scraper, and the leakage efficiency of the coating powder is low, which ultimately affects the feeding efficiency; In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0039] For details, see Figures 1-5 , this embodiment provides a powder coating feeding device, including a feeding box 10, a filter plate assembly and a discharge assembly;

[0040] Specifically, a feed port is formed at the upper end of the loading box 10 .

[0041] Specifically, the filter plate assembly includes a filter plate body 21 and a reciprocating drive module 30. The filter plate body 21 is slidably arranged in the loading box 10 along a first direction and has multiple filter holes 211 formed along the thickness direction. The reciprocating drive module 30 is arranged on the loading box 10 and is suitable for driving the filter plate body 21 to reciprocate along the first direction.

[0042] Specifically, the discharge assembly includes a discharge module 50 and a first driving member driving the discharge module 50 to move along the second direction. A first through slot 11 is provided on the loading box 10 in the second direction, and a sealing plate 60 is rotatably provided on the same side. The sealing plate 60 is suitable for blocking the first through slot 11. The discharge assembly is suitable for discharging the powder remaining on the filter plate body 21 through the first through slot 11 along the second direction.

[0043] In one embodiment, the first direction and the second direction are perpendicular to each other.

[0044] In the above solution, the staff pours the powder coating to be loaded into the loading box 10 from the feeding port. It will first pass through the filter plate main body 21. A plurality of filter holes 211 are formed on the filter plate main body 21. The qualified powder coating will pass through the filter holes 211 and further pass through the filter plate main body 21 for the next step of loading. The unqualified powder coating in the form of lumps will be blocked by the filter plate main body 21 on the filter plate main body 21 and cannot enter the next step. At this time, the lumpy powder coating can be screened out. At this time, the first driving member drives the discharging module 50 to move along the second direction. The staff opens the sealing plate 60 to connect the first through groove 11. The discharging module 50 can act on the residue remaining on the filter plate main body 21 and discharge it through the first through groove 11. In addition, during the process of loading and screening, the reciprocating driving module 30 drives the filter plate main body 21 to reciprocate along the first direction. During the reciprocating movement, due to the inertial effect, it will promote the qualified powder coating to quickly pass through the filter holes 211, thereby improving the loading efficiency. Further, it will reduce the probability of the qualified powder coating remaining on the filter plate main body 21, thereby reducing the waste of raw materials.

[0045] Specifically, please refer to Figures 4-5 The reciprocating driving module 30 includes a connecting block 33, a cross link 32, a mounting plate 31, a first rotary driving member, a rotating shaft 34 and a limiting roller 35;

[0046] Further, a longitudinal waist-shaped hole 321 is formed on the longitudinal rod of the cross link 32. One end of the rotating shaft 34 is connected to the driving end of the first rotary driving member, and the other end is provided with a convex column 341. The convex column 341 is limited in the longitudinal waist-shaped hole 321. The first rotary driving member and the limiting roller 35 are arranged on the mounting plate 31, and the mounting plate 31 is arranged on the loading box 10;

[0047] Further, a plurality of limiting rollers 35 are provided and distributed up and down to limit the transverse rod of the cross link 32 to drive the cross link 32 to move transversely. The connecting block 33 is connected to the cross link 32, and the filter plate main body 21 is connected to the connecting block 33;

[0048] In some other embodiments, other limiting methods can also be adopted, such as using a limiting slide rail to replace the limiting roller 35;

[0049] In the above solution, the first rotary driving member drives the rotating shaft 34 to rotate. The convex column 341 is arranged at the end of the rotating shaft 34 and thus rotates together with the rotating shaft 34. The convex column 341 is limited in the longitudinal waist-shaped hole of the cross link 32, and the transverse rod of the cross link 32 is limited by the limiting roller 35 and can only move transversely. Thus, under the drive of the rotating convex column 341 cooperating with the longitudinal waist-shaped hole, the cross link 32 will present a transverse reciprocating movement, and then can drive the connecting block 33 to reciprocate transversely. The connecting block 33 is connected to the filter plate main body 21, and thus the transverse reciprocating movement of the filter plate main body 21 is realized.

[0050] Specifically, please refer to Figure 5 , the filter plate main body 21 is detachably connected to the connecting block 33;

[0051] In the above implementation process, the filter plate main body 21 and the connecting block 33 are detachably connected, so that it is convenient for subsequent regular cleaning, and to avoid the blockage of some filter holes 211 caused by long-term use, which affects the normal feeding efficiency; further, it can be understood that it can be disassembled and installed through the first through groove 11, that is, the first through groove 11 is not only the discharge port for the residual material, but also provides space for the disassembly and installation of the filter plate main body 21.

[0052] Further, in one of the embodiments, a T-shaped groove is formed on the connecting block 33, and a T-shaped block 212 adapted to the T-shaped groove 331 is formed on one side of the filter plate main body 21;

[0053] In the above solution, the connecting block 33 and the filter plate main body 21 are detachably connected by means of plug-in connection, that is, the T-shaped block 212 of the filter plate main body 21 is aligned with the T-shaped groove 331 on the connecting block 33 and inserted, so as to realize the rapid connection of the two; it can be understood that the extending direction of the T-shaped groove 331 is the second direction.

[0054] Specifically, the first driving member includes a lead screw 41 and a rotary motor 42; the rotary motor 42 is arranged in the feeding box 10, the lead screw 41 passes through the discharging module 50 and is in threaded cooperation with the discharging module 50; the axial direction of the lead screw 41 is parallel to the second direction;

[0055] In the above solution, the rotary motor 42 drives the lead screw 41 to rotate, and the lead screw 41 is in threaded cooperation with the discharging module 50, so as to drive the discharging module 50 to move along the axial direction of the lead screw 41, that is, to move along the second direction.

[0056] Specifically, the discharging module 50 includes a fixing plate 51, a scraping plate 52 rotatably arranged on the fixing plate 51 and a second rotary driving member 53 arranged in the fixing plate 51;

[0057] Further, a receiving space is formed in the fixing plate 51, and the second rotary driving member 53 is arranged in the receiving space and its driving end is connected to the scraping plate 52;

[0058] Specifically, a threaded hole 54 in threaded cooperation with the lead screw 41 is formed on the fixing plate 51;

[0059] In the above solution, during discharging, it can be understood that the scraping plate 52 abuts against the surface of the filter plate body 21. As the scraping plate 52 moves along the second direction, it can export the residual material from the first through groove 11. When the scraping plate 52 resets, the second rotation driving member 53 can drive the scraping plate 52 to rotate by a certain angle, so that the scraping plate 52 does not abut against the filter plate body 21. Until it moves into place, the second rotation driving member 53 drives the scraping plate 52 to rotate again to make it abut against the filter plate body 21, preventing further accumulation of some powder coatings on the outermost side when the scraping plate 52 resets. In addition, when the reciprocating driving module 30 drives the filter plate body 21 to reciprocate, the second rotation driving member 53 can also drive the scraping plate 52 away from the surface of the filter plate body 21, so that there is no relative friction and the wear between the two is reduced.

[0060] Further, in some embodiments, a limiting hole 55 is further provided on the fixing plate 51, and a limiting rod 43 is provided in the feeding box 10. The limiting rod 43 is adapted to pass through the limiting hole 55 and its two ends are fixedly arranged on the inner wall of the feeding box 10.

[0061] In the above solution, the cooperation between the limiting rod 43 and the limiting hole 55 on the fixing plate 51 can limit the movement of the fixing plate 51, so that the discharging module 50 can stably move along the second direction.

[0062] Further, in some embodiments, the second rotation driving member 53 may not be provided. It can be understood that setting the second rotation driving member 53 is only one implementation manner, and this embodiment does not further limit it.

[0063] The above description is only a preferred embodiment of the present application, and does not impose any form of limitation on the present application. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application all belong to the scope of the technical solution of the present application.
