Description

Technical Field

[0001] The invention belongs to the field of water-based paint processing, and in particular relates to automatic feeding equipment for water-based paint processing. Background Art

[0002] Water-based paint has been widely used in many fields such as construction, industry and home decoration due to its advantages such as environmental protection and safety. Water-based paint mainly uses water as solvent. Compared with traditional solvent-based paint, it has the characteristics of low volatile organic compound content, low odor and fast drying.

[0003] Common water-based paints include latex paint, water-based anti-corrosion paint, and water-based epoxy paint. During processing, water needs to be injected into the processing dish first, then the dispersant is injected, and finally the pigment is added for the final mixing process.

[0004] At present, the raw materials of water-based paint are fed into the processing dish through automatic feeding equipment. Since different raw materials have different corresponding stirring rates when added, the traditional automatic feeding equipment cannot automatically switch the corresponding rotation speed of the stirring frame according to the type of raw materials fed in during feeding, and the function is relatively single. When discharging existing water-based paint, a fixed amount of raw materials are usually directly fed into the processing dish. This method of instantly feeding all the raw materials may cause a serious drop in the temperature in the processing dish, thereby affecting the processing quality. In addition, pouring in the raw materials instantly may also cause the raw materials to fail to be fully dispersed, especially in raw materials with larger particles such as pigments and fillers, which are prone to agglomeration and affect the dispersion effect.

A plurality of discharge ports 6 are provided on the inner side wall of the lower end of the storage chamber 2, which are evenly distributed in the circumferential direction and communicated with the feeding channel 4. A sealing mechanism 7 for controlling the opening and closing of the discharge ports 6 is provided on the processing box 1. A speed regulating mechanism 8 capable of switching the rotation speed of the main shaft 5 is provided between the main shaft 5 and the sealing mechanism 7. The injection pipe 17 is connected to an external feeding device, and a certain amount of ingredients are injected into each storage chamber 2 through the external feeding device. Then, the discharge ports 6 of each storage chamber 2 are opened from bottom to top through the sealing mechanism 7, and the ingredients in each storage chamber 2 are sent into the mixing chamber 3 through the feeding channel 4, and stirred by the stirring rod 20 at the lower end of the main shaft 5. When the sealing mechanism 7 opens the discharge port 6, it will synchronously drive the speed regulating mechanism 8 to operate, and the speed regulating mechanism 8 adjusts the rotation speed of the main shaft 5 to match the speed required for the current mixing of the ingredients.

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The sealing mechanism 7 includes a sealing ring 701 movably arranged in the material discharge channel 4, and the sealing ring 701 is movably fitted at the port of the material discharge port 6. A plurality of material baffles 16 with an annular structure are fixedly arranged in the material discharge channel 4, and each material baffle 16 is arranged above the adjacent sealing ring 701. A plurality of movable cavities 702 uniformly distributed along the circumferential direction are provided inside the processing box 1 below each material storage cavity 2, and a second bracket 703 with an L-shaped structure is fixedly arranged in the movable cavity 702.

[0031] In order to facilitate the feeding of ingredients according to the feeding sequence, the second bracket 703 is driven downward by the lifting component 704. During the downward movement, multiple second brackets 703 on the same horizontal plane jointly drive the same sealing ring 701 to move downward. Since the lengths of multiple sealing rings 701 in the vertical direction increase from bottom to top, the lowest sealing ring 701 will be staggered with the corresponding discharge port 6 first, and the ingredients in the lowest storage chamber 2 can first slide into the feeding channel 4 evenly and slowly through the discharge port 6, and finally enter the mixing chamber 3 to be mixed with the solvent for stirring. After stirring for a certain period of time, the lifting component 704 continues to move downward, so that the second sealing ring 701 below continues to move downward, and the discharge port 6 on the corresponding storage chamber 2 is opened for feeding, and this cycle is repeated until the ingredients in all storage chambers 2 are fed in sequence.

[0032] See also Figure 1 ,and Figure 4 The lifting assembly 704 includes four mounting plates 7041 fixedly arranged on the outer side wall of the lower end of the processing box 1 and evenly distributed along the circumferential direction, and any two opposite mounting plates 7041 are rotatably provided with screw rods 7042 on the upper parts, and the other two opposite mounting plates 7041 are fixedly provided with guide rods 7043 on the upper parts, and three ring plates 7044 are commonly threadedly connected on the two screw rods 7042, the top ring plate 7044 is connected to the speed regulating mechanism 8, the guide rod 7043 is movably plugged into the ring plate 7044, the inner circle of the ring plate 7044 is fixedly connected to multiple second brackets 703 on the same horizontal plane, and a second motor 7045 is fixedly arranged on the lower part of the mounting plate 7041 close to the screw rod 7042, and the output shaft of the second motor 7045 is fixedly connected to the lower end of the adjacent screw rod 7042. The screw rod 7042 is driven to rotate by the second motor 7045 so that the three ring plates 7044 can be raised and lowered simultaneously. The ring plates 7044 are fixedly connected to the second bracket 703 so that the corresponding sealing rings 701 can be driven to move downward when the ring plates 7044 move downward.

[0033] See also Figure 2 and Figure 3 A movable hole 9 connected to the material discharge channel 4 is provided on the inner wall of the upper end of the material storage chamber 2. The movable hole 9 extends in a circular direction and is annular. A connecting frame 10 is movably provided in the movable hole 9.

The end of the scraper plate 11 close to the connecting frame 10 is fixedly connected, and the end of the connecting frame 10 away from the scraper plate 11 is fixedly connected to the main shaft 5. When the main shaft 5 rotates, the scraper plate 11 can be driven to rotate by rotating the connecting frame 10 to fit on the lower inner wall of the material storage chamber 2, which is conducive to the full discharge of the ingredients in the material storage chamber 2.

[0034] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 The speed regulating mechanism 8 includes a mounting seat 801 fixedly arranged on the upper part of the processing box 1, and a plurality of gear rings 802 of different models are rotatably arranged on the mounting seat 801. A plurality of mounting grooves 12 are provided on the side of the mounting seat 801 close to the main shaft 5. A hollow connecting shaft 13 is rotatably arranged on the upper part of the mounting seat 801 and the lower inner wall of the plurality of mounting grooves 12 through bearings, and the upper end of each connecting shaft 13 is fixedly connected to the lower part of the adjacent gear ring 802; a plurality of gears 803 of different models are fixedly arranged on the upper end of the main shaft 5, and a gear set is formed between the corresponding gears 803 and the gear ring 802, and a driving assembly is arranged on the uppermost ring plate 7044, and the driving assembly includes a first bracket 804 fixedly arranged on the uppermost ring plate 7044, and a first motor 805 is fixedly arranged on the first bracket 804, and the output shaft of the first motor 805 is connected to a locking assembly 806 for controlling the rotation of the gear ring 802. The lifting assembly 704 can drive the sealing ring 701 downward and the locking assembly 806 downward at the same time, so that the locking assembly 806 can be inserted into the corresponding center position inside the gear ring 802, so that the locking assembly 806 can be locked with the gear ring 802, and then the locking assembly 806 is driven to rotate by the first motor 805 to rotate the gear ring 802, and the gear 803 meshing with the gear ring 802 cooperates to rotate the main shaft 5.

[0035] See also Figure 6 and Figure 7 The locking assembly 806 includes a locking plate 8061 fixedly connected to the output shaft of the first motor 805, and the locking plate 8061 is movably inserted into the inner ring of the gear ring 802. The outer wall of the locking plate 8061 is provided with a plurality of movable grooves that are evenly distributed in the circumferential direction and have a stepped structure, and a locking pin 8062 is movably arranged in the movable groove. The inner ring side wall of each gear ring 802 is provided with a plurality of limiting grooves 8021 that are evenly distributed in the circumference, and the locking pin 8062 and the limiting groove 8021 are connected to each other. 021 movable plug-in, an iron slide plate 8063 is fixedly provided at one end of the locking pin 8062 close to the center of the locking disk 8061, the slide plate 8063 is slidably set in the movable groove, an electromagnet 8064 is fixedly provided in the movable groove, a spring 8065 is fixedly provided on one side of the slide plate 8063 close to the locking pin 8062, the spring 8065 is sleeved on the surface of the locking pin 8062, and the end of the spring 8065 away from the slide plate 8063 is fixedly connected to the inner wall of the movable groove.

[0036] In order to be able to automatically switch the stirring speed according to the feeding object, when the lifting component 704 moves downward, the locking plate 8061 is driven downward by the first bracket 804. When moving downward, the locking plate 8061 can first enter the inner center position of the uppermost gear ring 802. At this time, the electromagnet 8064 is powered off, so that the iron slide plate 8063 originally adsorbed by the electromagnet 8064 in the movable groove loses its attraction, and the locking pin 8062 is driven to slide outward under the action of the spring 8065. At the same time, the first motor 805 drives the locking plate 8061 to rotate. During the rotation process, when the locking pin 8062 is aligned with the limiting groove 8021 on the inner ring side wall of the gear ring 802, the locking pin 8062 can be The first motor 805 drives the locking disk 8061 to rotate while driving the gear ring 802 to rotate, so that the gear ring 802 can drive the corresponding gear 803 to rotate. When the speed of the first motor 805 remains unchanged, the main shaft 5 rotates according to the speed output by the speed ratio of the gear group to drive the stirring rod 20 to stir, so as to meet the speed requirement of the current ingredients in the stirring chamber 3 during stirring. When the lifting assembly 704 opens the corresponding material storage chamber 2 from bottom to top in turn to feed different ingredients in sequence, the speed required by the main shaft 5 under the ingredient can be automatically and synchronously switched, so that the ingredients can be fully stirred at a reasonable speed.

[0037] See also Figure 4 A grinding nut 14 is fixedly provided on the inner wall of the feeding channel 4 below the top discharge port 6, and a grinding cavity with a narrow upper and wide lower structure is provided on the grinding nut 14. A grinding sub-holder 15 matching the grinding cavity is fixedly provided on the surface of the spindle 5, and the lower end of the grinding sub-holder 15 is rotatably provided in the grinding cavity.

[0038] In order to facilitate more thorough mixing of the ingredients in the subsequent step, when the ingredients (mainly pigments) stored at the top are discharged through the discharge port 6 into the feed channel 4, they will fall into the grinding chamber, and the main shaft 5 will drive the grinding sub-seat 15 to rotate, so that the ingredients in the grinding chamber can be further crushed. This is not only conducive to the ingredients entering the mixing chamber 3 for mixing and reducing the risk of agglomeration, but also avoids the trouble of grinding and refining the ingredients again after mixing. The operation is simpler, thereby improving the efficiency of the water-based paint in the entire processing process.

[0039] See also Figure 4 The lower end of the main shaft 5 is located above the stirring rod 20 and is provided with a sliding section 501 with a rectangular structure. The surface of the sliding section 501 is movably sleeved with a floating plate 21 that can float on the water surface. A through hole with a rectangular structure matching the sliding section 501 is opened in the middle position of the floating plate 21, and a plurality of material-discharging plates 22 evenly distributed along the circumferential direction are fixedly provided on the outer wall of the floating plate 21.

[0040] In order to improve the mixing efficiency of the ingredients after they fall into the mixing chamber 3, the floating plate 21 in the mixing chamber 3 always floats on the water surface, so that the material-discharging plate 22 on the floating plate 21 can always be in contact with the water surface. When the ingredients fall on the water surface, the floating plate 21 can rotate under the drive of the main shaft 5, and the material-discharging plate 22 can quickly break up the ingredients, which is conducive to the uniform and rapid dissolution of the ingredients into the water.

[0041] During specific operation, the lifting component 704 controls the corresponding storage chamber 2 to open from bottom to top in sequence, so that the ingredients in the corresponding storage chamber 2 can be evenly and slowly put into the mixing chamber 3 through the discharge channel 4. While the lifting component 704 drives the sealing ring 701 to open the discharge port 6 on the storage chamber 2, the lifting component 704 can also synchronously drive the speed regulating mechanism 8 to adjust the rotation speed of the main shaft 5, so that the rotation speed of the main shaft 5 can meet the rotation speed required by the current ingredients in the mixing chamber 3, thereby ensuring that the ingredients can be fully stirred at a suitable rotation speed.
