Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coating processing, more particularly to a coating stirring kettle. BACKGROUND

[0002] Coating is an important part of modern industry, which can form a film on the surface of an object under certain conditions to protect, decorate or have other special functions (insulation, rust prevention, mildew prevention, heat resistance, etc.). Coating generally contains four basic components, namely: film-forming material (resin, emulsion), pigment (including body pigment), solvent and additive (auxiliary agent), the type and ratio of components are important factors determining the performance of coating, and the processing of coating also involves whether the mixing is uniform, and the uniformity of coating mixing is also one of the important factors determining its performance and quality. At present, most coating processing plants add various ingredients of coating to the stirring kettle and use high-speed stirring machines (i.e. dispersion machines) for stirring.

[0003] In the prior art, a patent with publication number CN212523757U discloses an environmentally friendly artificial feeding dustproof stirring kettle, which comprises a kettle body and a feeding mechanism. The feeding mechanism comprises a motor and a feeding bin communicating with the kettle body. The kettle body is a cylindrical structure with a stirring port at the top. The feeding bin is arranged at one end of the kettle body near the top. The feeding bin is provided with a bin opening on the front side. A material placing groove is arranged inside the feeding bin. A bin door hinge shaft is arranged on the material placing groove. The material placing groove is hinged to the lower end of the bin opening of the feeding bin through the bin door hinge shaft. The motor is fixed on the kettle body, and the motor shaft is coaxially connected with the bin door hinge shaft. By arranging the feeding mechanism on the kettle body, the feeding mechanism rotates the material placing groove to realize automatic feeding, which maximally reduces dust emission and further provides health protection for the feeding personnel.

[0004] When preparing to feed, the above-mentioned patent discloses a stirring kettle. The button is actuated to make the motor rotate forward. The hatch shaft drives the material placing groove under the action of the motor shaft. The material placing groove rotates around the lower end of the bin door of the feeding bin to the outside of the feeding bin, i.e. opens the bin door. When the hatch is opened to a certain extent, the button is actuated to make the motor stop rotating. Then the material to be fed is placed in the material placing groove. The button is actuated again to make the motor rotate reversely. The material placing groove rotates around the lower end of the bin door of the feeding bin to the inside of the feeding bin. During the rotation of the material placing groove, the material enters the kettle body successively.

[0005] When opening and closing the bin door, it completely relies on manual visual angle to check the position of the bin door. When in place, the button is manually actuated to make the motor stop rotating. When rotating to the position, the staff may not control the motor to stop rotating in time due to negligence, which may cause the material placing groove to rotate excessively or even damage the equipment.

DETAILED DESCRIPTION

[0033] The conception, specific structure and generated technical effects of the utility model will be described clearly and completely in combination with the embodiments and the drawings below, so as to fully understand the purpose, features and effects of the utility model.

[0034] Embodiment 1

[0035] A paint stirring kettle, as shown in the drawings, comprises a kettle body 1, a stirring mechanism 2, a feeding bin 3, a material placing groove 4 and a driving control mechanism 5; Figures 1-5 The stirring mechanism 2 is assembled on the kettle body 1 and inserted into the kettle body 1;

[0036] The feeding bin 3 is arranged at one end of the kettle body 1 close to the top and communicated into the kettle body 1, the feeding bin 3 is provided with a bin mouth 31 at the front face, and the left and right side walls are both provided with a groove 32, and the groove 32 is provided with a first position sensor 33 and a second position sensor 34 for detecting the opening and closing to position of the bin mouth 31;

[0037] The material placing groove 4 is rotatably assembled on the feeding bin 3, and the left and right two ends of the material placing groove 4 are placed in the grooves 32, the material placing groove 4 comprises a bin door plate 41 and a guide plate 42 connected with each other, the included angle between the bin door plate 41 and the guide plate 42 is obtuse, and the feeding rotating shaft 43 is arranged between the bin door plate 41 and the guide plate 42;

[0038]

[0039] ​The driving control mechanism 5 is drivingly connected with the feeding shaft 43 and is electrically connected with the stirring mechanism 2, the first position sensor 33 and the second position sensor 34 respectively;

[0040] The driving control mechanism 5 drives the feeding shaft 43 to rotate forward to drive the feeding groove 4 to rotate, so that the door plate 41 gradually opens the opening 31. When the guide plate 42 of the feeding groove 4 rotates to touch the first position sensor 33, the driving control mechanism 5 drives the feeding groove 4 to stop rotating, and the door plate 41 opens the opening 31 to the position. Then the material to be fed is placed in the feeding groove 4.

[0041] The driving control mechanism 5 drives the feeding shaft 43 to rotate reversely to drive the feeding groove 4 to rotate, so that the door plate 41 gradually closes the opening 31. When the guide plate 42 of the feeding groove 4 rotates to touch the second position sensor 34, the driving control mechanism 5 drives the feeding groove 4 to stop rotating, and the door plate 41 closes the opening 31 to the position. During the closing process, the material in the feeding groove 4 enters the kettle body 1 through the guide plate 42.

[0042] In the embodiment, the kettle body 1 is the main structure of the paint stirring kettle; the stirring mechanism 2 is used for stirring the paint raw material in the kettle body 1; the feeding bin 3 is used for feeding the kettle body 1; the feeding groove 4 is used for loading the paint raw material for feeding; and the driving control mechanism 5 is used for controlling the operation of the paint stirring kettle, including stirring and feeding.

[0043] In the embodiment, the first position sensor 33, the second position sensor 34 and the driving control mechanism 5 are arranged, and the driving control mechanism 5, the first position sensor 33 and the second position sensor 34 are used to control the feeding groove 4 to open and close the opening 31 and stop automatically.

[0044] In addition, the driving control mechanism 5 drives the material in the feeding groove 4 to be automatically fed into the kettle body 1 for automatic feeding. When feeding the kettle body 1, the staff can be away from the opening 31 of the feeding bin 3 to avoid dust, and the opening 31 of the feeding bin 3 is on the side of the kettle body 1, which avoids a large amount of dust directly gushing out compared with feeding from the top of the kettle body 1. In addition, the door plate 41 of the feeding bin 3 is in a closed or semi-closed state when the material enters the kettle body 1, which further avoids a small amount of dust in the feeding bin 3 from gushing out of the opening 31.

[0045] Embodiment 2

That is, when the flow guide plate 42 rotates forward and touches the first position sensor 33, the first position sensor 33 is triggered, and the first position sensor 33 sends a signal to the driving control mechanism 5, which controls the material placing groove 4 to stop rotating, and the door plate 41 opens the hopper 31 to the right position. When the flow guide plate 42 rotates in the opposite direction and touches the second position sensor 34, the second position sensor 34 is triggered, and the second position sensor 34 sends a signal to the driving control mechanism 5, which controls the material placing groove 4 to stop rotating, and the door plate 41 closes the hopper 31 to the right position.
