DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] like Figures 1 to 10As shown, a multi-stage adjustable feeding device for coating raw materials is used for feeding coating raw materials into a coating raw material stirring kettle, which includes a hollow storage box 1, and a feeding box 2 is installed at the bottom of the storage box 1; a horizontally arranged motor 3 is fixedly installed in the feeding box 2, and a driving barrel 4 is concentrically connected to the rotating shaft of the motor 3, and a resistance protrusion 5 is slidably installed on the outer wall of the driving barrel 4; a feeding port is opened between the storage box 1 and the feeding box 2, and a material control valve core 6 that can completely block the feeding port is movably installed at the feeding port; a vertically arranged touch rod 7 is fixed to the bottom of the touch rod 7, and a push piece 8 is fixed on the rod body of the touch rod 7 , the push piece 8 is slidably installed on a guide rod 9 fixed around the material port, and the guide rod 9 is equipped with a spring 10 that pushes the push piece 8 to slide downward; when the driving barrel 4 is driven to rotate by the motor 3, the touch rod 7 will be pushed upward when passing the interference protrusion 5, and the material port will be opened. Then the material control valve core 6 rebounds and resets under the action of the spring 10, so as to perform intermittent material unloading; there are three interference protrusions 5 installed, and all the interference protrusions 5 are distributed in a circular array on the outer wall of the driving barrel 4 in sequence, and the height of each interference protrusion 5 is different, and each interference protrusion 5 can slide along the axial direction of the driving barrel 4 to just below the touch rod 7. When the driving barrel 4 is driven to rotate by the motor 3, the feeler rod 7 will be pushed upward when passing the abutment protrusion 5, and the material port will be opened. Then the material control valve core 6 will rebound and reset under the action of the spring 10, so as to perform intermittent material discharge. The device is provided with three abutment protrusions 5 at different heights, that is, the device has three levels of feeding modes for adjustment, which can drive the material control valve core 6 to be lifted to different heights respectively, thereby controlling different feeding amounts per unit time, and has better flexibility and adaptability when used.

[0049] like Figure 6 As shown, the top of the material control valve core 6 is shaped like a "wok lid," and the bottom of the material control valve core 6 is shaped like a "wok bottom." When the material control valve core 6 is pushed to open the material opening, the material in the material storage box 1 falls toward the location of the contact rod 7. To ensure that the material opening is blocked by the material control valve core 6, the bottom of the material control valve core 6 is designed to be shaped like a "wok bottom." The bottom of the material control valve core 6 can completely match the material opening, thereby achieving sealing of the material opening.

[0050] like Figure 6 As shown, the lower end of the feeler rod 7 and the middle end of the abutting protrusion 5 are both rounded. In order to reduce wear between the feeler rod 7 and the abutting protrusion 5, the contacting ends of the two are both designed to be rounded, which reduces the friction between the two during contact and thus prolongs the service life of the two.

[0051] like Figure 10As shown, both sides of the abutting protrusion 5 are inclined slopes. In order to ensure that the material control valve core 6 can be more smoothly raised or lowered, the two sides of the abutting protrusion 5 are inclined slopes. Then, when the slopes abut the lower end of the contact rod 7, the material control valve core 6 can be raised or lowered smoothly, which makes the material control valve core 6 more smooth when it is raised or lowered.

[0052] like Figure 11 As shown, the interference protrusion 5 is slidably mounted on a second guide rod 11 fixed inside the drive barrel 4. The second guide rod 11 is sleeved with a second spring 12 that pushes the interference protrusion 5 away from the location of the motor 3. In order to achieve automatic reset of the interference protrusion 5, the second spring 12 is provided to push the interference protrusion 5. When the hand-cranked screw 13 no longer pushes the interference protrusion 5, the interference protrusion 5 will automatically reset.

[0053] like Figure 11 As shown, a screw hole is formed through the end of the driving barrel 4 away from the motor 3 at the corresponding position of each interference protrusion 5, and a hand screw 13 is fitted in the screw hole. A limit hole 14 is formed on the side of the interference protrusion 5 facing the hand screw 13, and the rod head of the hand screw 13 can be assembled in the limit hole 14. In order to facilitate pushing the interference protrusion 5 to the bottom of the contact rod 7, the interference protrusion 5 can be pushed to the bottom of the contact rod 7 by rotating the hand screw 13, which is more convenient in use.

[0054] like Figure 11 As shown, covers 15 distributed along the axial direction of the drive barrel 4 are fixedly installed on both sides of the abutting protrusion 5. In order to prevent the raw materials from entering the drive barrel 4, the covers 15 can effectively prevent the raw materials from entering the drive barrel 4.

[0055] like Figure 7 As shown, a tilted offset plate 16 is fixed at the feeding port below the feeding box 2, and the offset plate 16 is located directly below the driving barrel 4. In order to facilitate the guidance of the raw materials during feeding, a bias plate 16 is installed to facilitate the feeding of the raw materials to a specific position.

[0056] like Figure 3 Shown, the top of the storage box 1 is fixed with a detachable box cover 17. In order to facilitate the storage box 1 to put raw materials, the detachable box cover 17 is poured into the storage box 1.

[0057] like Figure 4 As shown, an L-shaped suspension arm 18 is fixedly mounted on the bottom of the feeding box 2. The multi-stage adjustable feeding device for the coating raw material is suspended and fixed directly above the coating raw material mixing kettle via the L-shaped suspension arm 18. To facilitate the overall fixation of the multi-stage adjustable feeding device for the coating raw material, the L-shaped suspension arm 18 is suspended and fixed directly above the coating raw material mixing kettle so as not to occupy space on the ground.

[0058] The working principle of this utility model:

[0059] During use, the starting motor 3 can drive the driving barrel 4 to rotate, and the touch rod 7 will be pushed upward when it passes the resistance bump 5. At this time, the material port will open, and then the material control valve core 6 will rebound and reset under the action of the spring 10, so as to perform intermittent material unloading.

[0060] Since the device is slidably installed with three interference protrusions 5 of different heights, the device has three levels of feeding modes for adjustment. When replacing different interference protrusions 5, the different interference protrusions 5 can be pushed to the bottom of the touch rod 7 by rotating the hand-cranked screw 13, which can drive the material control valve core 6 to rise to different heights respectively, thereby controlling different feeding amounts per unit time. It has better flexibility and adaptability when used.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
