DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further specifically described below in conjunction with the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a quantitative filling device for enameled wire paint, comprising a discharge box 1, a feed port 2 and a controller. A negative pressure device connecting port 3 is provided on one side of the discharge box 1. The negative pressure device connecting port 3 is externally connected to a negative pressure generating device to provide negative pressure in the discharge box 1, thereby increasing the falling power of the viscous enameled wire paint to a certain extent, thereby ensuring that the filling work is completed more smoothly.

[0019] The lower end of the discharge box 1 is evenly provided with a plurality of inverted truncated cone-shaped discharge ports 4, and the lower end of the discharge port 4 is coaxially and closely provided with a baffle plate 5 which can be flipped and can close and open the discharge port 4 by flipping. When the discharge port 4 is closed, it waits for the next paint bucket 10 to be filled to be in place, and when the discharge port 4 is opened, the quantitative filling work of the paint bucket 10 in place is completed.

[0020] The outer diameter of the baffle plate 5 is larger than the aperture of the discharge port 4, so that it is completely closed. A detachable elastic plate 12 is tightly laid on the upper end of the baffle plate 5, that is, the elastic plate 12 has the same shape as the baffle plate 5, and the elastic plate 12 is detachable, which is convenient for maintenance and repair work to be completed by replacement later.

[0021] A common rotating rod 6 is fixedly connected to the same side of the multiple material baffle plates 5, and a rotating motor 8 is provided at one end of the rotating rod 6 for driving the rotating rod 6 to rotate. Specifically, the multiple material baffle plates 5 can rotate together with the rotating rod 6 under the drive of the rotating motor 8, thereby realizing the synchronous closing and opening of the multiple material discharge ports 4 by the multiple material baffle plates 5 in a one-to-one correspondence.

[0022] The rotary motor 8 is electrically connected to the controller, and the rotary motor 8 works regularly under the control of the controller, thereby completing the quantitative filling of the paint bucket 10 .

[0023] The outer diameter of the material blocking plate 5 is set larger than the outer diameter of the lower end of the material discharge port 4 so as to better complete the sealing work of the lower end of the material discharge port 4.

[0024] The baffle plate 5 is a curved surface structure, which is convenient for accommodating a certain amount of wire enamel before complete sealing, thereby avoiding the waste of raw materials caused by the outflow of wire enamel during this period.

[0025] Specifically, the feed port 4, the baffle plate 5 and the paint bucket mouth of the paint bucket 10 below are coaxial, that is, the paint bucket is located directly below the feed port 4 and the baffle plate 5, and the outer diameter of the baffle plate 5 is smaller than the diameter of the paint bucket mouth, that is, during the period when the baffle plate 5 rotates and completes the opening of the feed port 4, the lower end of the baffle plate 5 always falls within the upper range of the paint bucket mouth, that is, the enameled wire paint contained in the curved surface structure can be completely dropped into the paint bucket 10 without causing waste.

[0026] The upper end surface of the baffle plate 5 is provided with a plurality of evenly distributed limiting grooves 51, and the lower end surface of the elastic plate 12 is provided with a plurality of limiting protrusions 121 which correspond one-to-one and match the plurality of limiting grooves 51. The elastic plate 12 is detachably laid on the upper end of the baffle plate 5 after being embedded one-to-one in the plurality of limiting grooves 51 through the plurality of limiting protrusions 121.

[0027] Two symmetrical triangular support frames 7 are provided on both sides of the lower end of the discharge box 1. The two ends of the rotating rod 6 are rotatably connected to the lower ends of the two triangular support frames 7 through bearings 9. The triangular support frames 7 and the two bearings 9 provide stable and reliable rotation support for the rotating rod 6.

[0028] The rotation angle of the rotating rod 6 is not less than 90 degrees. When the rotation angle is 90 degrees, the baffle plate 5 is just perpendicular to the mouth of the paint bucket. At this time, the baffle plate 5 completes the full opening of the feed opening 4, that is, the enameled wire paint falling from the feed opening 4 completely falls into the mouth of the paint bucket. It should not be too large, generally within 95 degrees, so as to avoid excessive or insufficient.

[0029] After completing the above installation, the utility model can be put into use. Under the control of the controller, the rotating motor 8 works regularly, that is, the baffle plate 5 regularly completes the opening and closing of the discharge port 4, and completes the filling work of the paint bucket 10 located directly below the discharge port 4 during the opening period, and completes the blocking of the enameled wire paint and the next paint bucket 10 to be filled during the closing period. This cycle is repeated to complete the quantitative filling work of the paint bucket 10 with the enameled wire paint stored in the discharge box 1; during this period, negative pressure is regularly introduced, that is, negative pressure is introduced during the filling work, and the negative pressure is released during the work when the paint bucket 10 is in place, so that with the assistance of negative pressure, the device can better complete the quantitative filling work as a whole.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
