DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0020] like Figures 1 to 5 As shown, a drum-type paint stirring device comprises a stirring drum 1 and a transmission mechanism 5, wherein a bracket 4 is arranged at the bottom of the stirring drum 1, a filter plate 7 is arranged on the inner wall of the middle part of the stirring drum 1, an inlet 2 and an outlet 3 of the paint are arranged on the outer wall of the middle part of the stirring drum 1, and flow holes 8 are evenly arranged on the filter plate 7, and each inlet 2 and outlet 3 are connected with the adjacent flow holes 8, and pistons 6 are respectively arranged on both sides of the filter plate 7 inside the stirring drum 1 to seal and slide with the inner wall of the stirring drum 1; a first fixing rod 9 is fixedly arranged on the side of the piston 6 facing the drum cover of the stirring drum 1, and a second fixing rod 1 is fixedly arranged on the inner wall of the drum cover of the stirring drum 1 0, a telescopic frame 11 is arranged between the first fixed rod 9 and the second fixed rod 10 on the same side, and the push rods at both ends of the telescopic frame 11 are provided with sliders 12 that slide with the fixed rods; the transmission mechanism 5 includes a first pin shaft 51, a directional push shaft 52 and a driving device, the first pin shaft 51 and the directional push shaft 52 are arranged on both sides of the mixing drum 1, the shaft part of the telescopic frame 11 facing the drum cover is movably connected with the first pin shaft 51, the first pin shaft 51 is fixedly connected with the directional push shaft 52 on the same side, the directional push shaft 52 slides with the drum cover, and the driving device is connected with each directional push shaft 52 and controls the synchronous displacement of the directional push shafts 52 on both sides of the mixing drum 1.

[0021] like Figure 2 and Figure 3As shown, the driving device includes a rocker 54, a base 55, a telescopic rod 56 and a motor. The base 55 is arranged on both sides of the mixing drum 1. The rocker 54 is vertically rotatably arranged on the base 55. A vertical long hole is arranged on the top of the rocker 54. A second pin 53 is arranged on the directional push shaft 52 to penetrate into the long hole and slide with the rocker 54. The telescopic rod 56 passes through the bracket 4 and is rotatably connected between the rockers 54. An ear plate is arranged on the base 55 on one side. A crank 57 is rotatably arranged on the ear plate. A connecting rod 58 is rotatably arranged between the crank 57 and the end of the telescopic rod 56. The motor is connected to the crank 57 to drive the crank 57 to rotate circumferentially. When stirring, the paint is injected into the mixing drum 1 through the inlet 2 and released through the outlet 3 after stirring. The telescopic rod 56 is set to a fixed length, and the transmission mechanism is responsible for making the two pistons move synchronously. The motor drives the crank 57 to rotate in a circumferential direction, so that the crank 57 pulls the connecting rod 58, and then the connecting rod 58 pulls the rocking rod 54 back and forth to swing left and right. When the connecting rod 58 pulls one rocking rod 54 to swing left and right, the other rocking rod swings left and right synchronously due to the traction of the telescopic rod 56.

[0022] When the two rockers 54 swing to the left at the same time:

[0023] The movement mode of the left transmission mechanism is that the rocker 54 pulls the directional push shaft 52 toward the outside of the cylinder, and at the same time the first pin 51 is also pulled toward the cylinder cover, so that the telescopic frame 11 is pulled back and contracted, and the sliders 12 on the first fixed rod 9 and the second fixed rod 10 are lengthened due to the contraction of the telescopic frame 11, and the distance between the first fixed rod 9 and the second fixed rod 10 is also shortened. Since the first fixed rod 9 and the second fixed rod 10 are fixedly connected to the piston 9 and the cylinder cover respectively through the ear plates, the piston 9 on the left side moves toward the cylinder cover, thereby expanding the space between the left piston 9 and the filter plate 7.

[0024] The movement mode of the right transmission mechanism is that the rocker 54 pushes the directional push shaft 52 toward the piston 6, and at the same time the first pin shaft 51 is also pushed toward the piston 6, so that the telescopic frame 11 is pushed and extended, and the sliders 12 on the first fixed rod 9 and the second fixed rod 10 retract due to the extension of the telescopic frame 11, and the distance between the first fixed rod 9 and the second fixed rod 10 is also increased. Since the first fixed rod 9 and the second fixed rod 10 are fixedly connected to the piston 9 and the cylinder cover respectively through the ear plates, the piston 9 on the right side moves toward the filter plate 7, reducing the space between the right side piston 9 and the filter plate 7.

[0025] When the two rocking arms 54 swing to the right at the same time, the left transmission mechanism and the right transmission mechanism move in opposite directions as described above, so that the left piston 9 moves toward the filter plate 7, reducing the space between the left piston 9 and the filter plate 7, and the right piston 9 moves toward the cylinder cover, expanding the space between the right piston 9 and the filter plate 7.

[0026] The two pistons 6 in the mixing drum 1 are displaced synchronously, so that the size of the space between the two sides of the filter plate 7 and the pistons 6 changes synchronously. The paint repeatedly flows on both sides of the filter plate 7 due to the squeezing of the two pistons 6, which causes the paint between the pistons 6 to flow and mix on both sides of the filter plate 7 through the flow holes 8, forming turbulence, which is easier to adapt to the components of various paints, saves manpower, and has high mixing efficiency.

[0027] When the paint is released, the telescopic frame 11 is adjusted from a fixed length to retract inward at both ends, and at the same time, the two rocking arms 54 are pulled to swing toward the mixing drum 1, thereby simultaneously driving the two pistons 6 to move toward the filter plate 7, squeezing the stirred paint toward the filter plate 7 until the protrusions 61 on the two pistons 6 are inserted into the flow holes 8 and abut against each other, so that all the paint flows out from the outlet 3.

[0028] The piston 6 is provided with three grooves in the circumferential direction, and a sealing ring 62 is provided in each groove, so that a sealing fit is formed between the piston 6 and the inner wall of the mixing drum 1 to prevent paint leakage.

[0029] like Figure 4 and Figure 5 As shown, the flow holes 8 on the filter plate 7 are distributed in layers, and a liquid channel 13 is provided inside the filter plate 7 between the flow holes 8 on the same layer and the adjacent layer. The piston 6 is provided with protrusions 61 corresponding to the flow holes 8 on the filter plate 7. The protrusions 61 on the left and right sides of the same flow hole 8 can be inserted into the flow hole 8, and there is a gap between the protrusions 61 and the flow hole 8. After the two protrusions 61 are inserted into the flow hole 8, they are in abutting position. The liquid channel 13 between the flow holes 8 can squeeze out all the paint remaining in the flow hole 8 after the protrusion 61 is inserted into the flow hole 8. The paint flows downward through the liquid channel 13 to the flow hole 8 connected to the outlet 3, and is finally released from the outlet 3. This design can save material costs, avoid waste, and facilitate the subsequent cleaning work in the cylinder.

[0030] The outer wall of the middle part of the mixing drum 1 is a regular polygon structure, and the inlet 2 and the outlet 3 are both arranged on the plane of the outer wall of the middle part of the mixing drum 1, wherein the inlet 2 is located in the upper half of the mixing drum 1, and the outlet 3 is located in the lower half of the mixing drum 1. The middle part of the mixing drum 1 is designed as a regular polygon, which can provide a plane position for the inlet 2 and the outlet 3, and is convenient for the installation of the inlet 2 and the outlet 3. The inlet 2 is located in the upper half, and the outlet 3 is located in the lower half, which is also convenient for the injection and release of paint.

[0031] 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 principle of the present invention should be included in the protection scope of the present invention.
