Description

Technical Field

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Powder coating is completely different from general coatings. It exists in the form of fine powder. Since no solvent is used, it is called powder coating. When processing and producing powder coating, different processing and production equipment is required to effectively improve the overall production efficiency. Therefore, extrusion equipment is required in the processing and production of powder coating.

When the cutter rotates to a state almost parallel to the feed tooth plate, the mixture extruded from the forming part is cut off by the cutters on both sides. When it is necessary to cut into large pieces, the scraping motor 1 and the scraping motor 2 are used to keep the cutter on the first scraping mechanism and the feed tooth plate at a large inclination angle. At this time, the mixture extruded from the forming part is cut off by the cutter but will not fall off under the support of the cutter.

[0018] 2. The present invention can further improve the mixing efficiency and mixing effect of raw materials through the storage cylinder and the stirring motor. When the unloading motor drives the unloading gear ring to move, multiple groups of raw materials in the raw material bin fall into the stirring device according to a certain proportion. This design is ingenious and effective, which improves the degree of freedom and stirring efficiency of the high-efficiency extruder used for powder coating production.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides an efficient extruder for powder coating production by improving Figure 1-Figure 9As shown, it includes a stirring device 1 and a molding device 2.

When the inner cylinder 224 and the outer cylinder 225 are rotated and matched in different ways, the cutters 228 on both sides cut the raw materials into columns or large pieces.

[0034] In this embodiment: the high-efficiency extruder for powder coating production is mainly divided into two parts: a stirring device 1 and a molding device 2. When the device is in use, firstly, a variety of raw materials are respectively placed in the raw material bin 103, and then the stirring motor 116 and the unloading motor 111 are started when unloading is required. At this time, various raw materials fall into the stirring device 1 according to a certain proportion, and the mixed raw materials enter the molding cylinder 201 under the drive of the spiral fan 117 and the spiral fan 218. In the early stage of molding, the quality of the mixture extruded from the molding part 218 is general. At this time, the cutter 228 is swung downward to a vertical position to discharge the waste in the early stage. When it is necessary to cut the mixed raw materials into a columnar shape, the cutters 228 on the first scraping mechanism 212 and the second scraping mechanism 213 are rotated to a state that is almost parallel to the unloading tooth plate 217, and the mixture extruded from the molding part 218 is cut off by the cutters 228 on both sides. When it is necessary to cut into large pieces, the cutter 228 on the first scraping mechanism 212 is kept at a large inclination angle with the unloading tooth plate 217. At this time, the mixture extruded from the forming part 218 is cut off by the cutter 228, and the cutter 228 drives the raw material to rotate. When it moves to the coating part 219, the paint is coated on the coating part 219. When the coating part 219 moves to the cutter 228 on the second scraping mechanism 213, the raw material on the coating part 219 is scraped by the cutter 228 into larger pieces.

[0035] See attached Figure 1 -Attached Figure 3 The bottom of the raw material bin 103 is provided with an independent discharge pipe 105, and a control valve 106 is installed in the middle of the discharge pipe 105; the bottom of the storage cylinder 102 is provided with a limit ring 107 that cooperates with the stirring device 1, and a bearing 108 is installed on the inner wall of the limit ring 107; a discharge gear ring 109 is installed on the outer wall of the storage cylinder 102, and a mounting plate 110 is provided on the outer wall of the stirring device 1, and a discharge motor 111 is installed on the mounting plate 110, and a discharge gear 112 meshing with the discharge gear ring 109 is installed at the output end of the discharge motor 111.

[0036] In this embodiment, since the stirring motor 116 has both stirring and conveying functions, a rotating material discharge storage cylinder 102 is designed in order to fully stir the raw materials in a relatively short time. When the storage cylinder 102 rotates, the raw materials in each raw material bin 103 fall into the stirring device 1 and the preliminary mixing is completed. In order to drive the storage cylinder 102 to rotate automatically, a material discharge motor 111 structure is designed.

[0037] See attached Figure 1 -Attached Figure 2 A plurality of upwardly directed support frames 113 are connected to the outer wall of the stirring device 1, a stirring motor 116 is mounted on the top of the support frames 113, a through hole 104 cooperating with the stirring motor 116 is provided in the middle of the storage cylinder 102; a spiral fan 117 cooperating with the stirring device 1 and a spiral fan 2 118 cooperating with the forming cylinder 201 are provided at the output end of the stirring motor 116.

[0038] In this embodiment, when the storage barrel 102 rotates, a through hole 104 is provided in the middle thereof to avoid interference with the stirring motor 116. In order to efficiently transport the raw materials, a screw fan 1 117 and a screw fan 2 118 structure with different diameters are designed.

[0039] See attached Figure 1 -Attached Figure 2 A control panel 114 is disposed on the outer wall of the support frame 113 , a plurality of groups of downwardly directed support legs 101 are disposed on the outer wall of the stirring device 1 , and a plurality of groups of heating tubes 115 are disposed on the inner wall of the stirring device 1 .

[0040] In this embodiment, in order to quickly fuse the raw materials, a heating tube 115 structure is designed. In order to control the operation of the equipment, a control panel 114 structure is designed.

[0041] See attached Figure 4 -Attached Figure 5A T-shaped rail 209 is provided at the bottom of the annular gear plate 207, and a T-shaped cavity 208 matching with it is opened at the top of the rotating cavity 206; a forming motor 210 is installed on the top of the boss 205, and a driving gear 211 meshing with the annular gear plate 207 is installed at the output end of the forming motor 210.

[0042] In this embodiment, in order to drive the annular tooth plate 207 to rotate, thereby driving the first scraping mechanism 212 and the second scraping mechanism 213 to smear or cut the raw material extruded from the bottom of the unloading tooth plate 217, a forming motor 210 structure is designed.

[0043] See attached Figure 4 -Attached Figure 6 A cooling cavity 202 is provided on the outer wall of the forming cylinder 201 , and an air inlet pipe 203 and an exhaust pipe 204 are provided on the cooling cavity 202 .

[0044] In this embodiment, in order to cool down the high-temperature raw materials and thus facilitate the subsequent molding operation, a cooling chamber 202 is designed, and low-temperature gas is transported into the chamber through an external cooling device.

[0045] See attached Figure 4 -Attached Figure 6 A device bin 215 is also provided in the middle of the forming cylinder 201, and the outer wall of the device bin 215 is connected to the inner wall of the forming cylinder 201 through multiple sets of connecting arms 216; a rotating motor 220 is installed in the device bin 215, and a driving gear 221 meshing with a feeding tooth plate 217 is installed at the output end of the rotating motor 220.

[0046] In this embodiment, in order to drive the unloading tooth plate 217 to rotate, so as to cooperate with the outer annular tooth plate 207 to further improve the forming efficiency, the unloading tooth plate 217 is designed to be a rotatable structure.

[0047] See attached Figure 6 -Attached Figure 8 A deflection gear 229 is installed on the outer wall of the inner cylinder 224, and a linkage member 230 is installed on the outer wall of the outer cylinder 225. The linkage member 230 includes a deflection gear 231 and a first bevel gear 232 fixedly arranged on the top thereof, and a second bevel gear 233 meshing with the first bevel gear 232 is fixedly installed on the inner wall of the swing seat 227; a symmetrical scraping motor 1 234 and a scraping motor 2 236 are installed on the inner wall of the mounting frame 223, and a scraping gear 235 meshing with the deflection gear 229 is installed at the output end of the scraping motor 234, and a scraping gear 237 meshing with the deflection gear 231 is installed at the output end of the scraping motor 236.

[0048] In this embodiment: when the scraping motor 1 234 and the scraping motor 2 236 are started synchronously and have the same rotation speed, the swing seat 227 drives the cutter 228 to rotate. When the scraping motor 2 236 drives the deflection gear 1 229 to rotate and the scraping motor 2 236 is not started, the swing seat 227 drives the cutter 228 to swing rapidly. When the scraping motor 2 236 drives the deflection gear 2 231 to rotate and the scraping motor 2 236 is not started, the swing seat 227 drives the cutter 228 to swing rapidly under the cooperation of the first bevel gear 232 and the second bevel gear 233.

[0049] When the mixed raw materials need to be cut into columns, the scraping motor 1 234 and the scraping motor 2 236 on the first scraping mechanism 212 and the second scraping mechanism 213 are started synchronously and rotate at the same speed, and the swing seat 227 drives the cutter 228 to rotate. When the cutter 228 rotates to a state that is almost parallel to the unloading tooth plate 217, the blade of the cutter 228 abuts against it, and the mixture extruded from the forming part 218 is cut by the cutters 228 on both sides. When it is necessary to cut into large pieces, the scraping motor 1 234 and the scraping motor 236 keep the cutter 228 on the first scraping mechanism 212 at a large tilt angle with the unloading tooth plate 217, and the mixture extruded from the forming part 218 is smeared by the cutter 228, and the forward direction is the same as the direction of the inclined acute angle, but it will not fall down under the support of the cutter 228. When the coating part 219 is moved to the coating part 219, the inclination angle between the cutter 228 and the feeding tooth plate 217 is reduced, and the coating is coated on the coating part 219, and the coating thickness can be adjusted by the lifting cylinder 222. When the coating part 219 moves to the cutter 228 on the second scraping mechanism 213, the cutter 228 and the feeding tooth plate 217 are kept almost parallel, and the raw material on the coating part 219 is scraped into a larger sheet by the cutter 228.

[0050] In the initial stage of forming, since the raw materials have not yet been compacted by the screw fan 117 and the screw fan 2 118, the quality of the mixture extruded from the forming part 218 is average. At this time, the cutter 228 is swung downward to a vertical position to discharge the early waste.

[0051] See attached Figure 8 -Attached Fig. 9 A mounting rail 238 is fixedly provided at the bottom of the inner cylinder 224, and a mounting groove 239 cooperating therewith is provided on the outer wall of the mounting frame 223; a limiting convex ring 240 is provided on the outer wall of the inner cylinder 224, and a limiting groove 241 cooperating therewith is provided on the inner wall of the outer cylinder 225.

[0052] In this embodiment, in order to ensure that the inner cylinder 224 can rotate freely relative to the outer wall of the mounting frame 223, a mutually matching mounting rail 238 and mounting groove 239 structure is designed. In order to ensure that the outer cylinder 225 can rotate freely relative to the inner cylinder 224, a mutually matching limiting convex ring 240 and limiting groove 241 structure is designed.

[0053] Working principle of the present invention: When the device is in use, firstly, various raw materials are placed in the raw material bin 103 respectively, and then the stirring motor 116 and the unloading motor 111 are started when unloading is required. At this time, various raw materials fall into the stirring device 1 according to a certain proportion, and the mixed raw materials enter the forming cylinder 201 under the drive of the spiral fan 117 and the spiral fan 218. In the early stage of molding, the quality of the mixture extruded from the molding part 218 is average. At this time, the cutter 228 is swung downward to a vertical position to discharge the early waste. When it is necessary to cut the mixed raw materials into a column, the cutters 228 on the first scraping mechanism 212 and the second scraping mechanism 213 are rotated to a state almost parallel to the unloading tooth plate 217. At this time, the mixture extruded from the molding part 218 is cut off by the cutters 228 on both sides. When it is necessary to cut into large pieces, the cutter 228 on the first scraping mechanism 212 is kept at a large inclination angle with the unloading tooth plate 217. At this time, the mixture extruded from the forming part 218 is cut off by the cutter 228, and the cutter 228 drives the raw material to rotate. When it moves to the coating part 219, the paint is coated on the coating part 219. When the coating part 219 moves to the cutter 228 on the second scraping mechanism 213, the raw material on the coating part 219 is scraped by the cutter 228 into larger pieces.
