[0001] This utility model relates to the field of coating construction technology, and in particular to a roller-type paint mixing device. Background Technology

[0002] In the current painting process, the existing painting techniques are relatively traditional, with the conventional operation involving manual mixing on-site using a mixer. This method has several drawbacks, including uneven paint ratios, waste of paint materials, wasted labor, and low mixing efficiency. Therefore, there is an urgent need for a paint mixing device that can reduce manual labor, increase mixing efficiency, and fully utilize the mixed paint. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a paint mixing device that can reduce manual operation, has high mixing efficiency, and can make full use of the mixed paint.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A drum-type paint mixing device includes a mixing drum and a transmission mechanism. The bottom of the mixing drum is supported by brackets at both ends. A filter plate is installed on the inner wall of the middle section of the mixing drum, and paint inlets and outlets are respectively provided on the outer wall of the middle section. Flow holes are evenly distributed on the filter plate, and each inlet and outlet communicates with an adjacent flow hole. Inside the mixing drum, pistons are respectively installed on both sides of the filter plate, which are in a sealing and sliding fit with the inner wall of the mixing drum. A first fixing rod is fixedly installed on the side of each piston facing the mixing drum cover, and a second fixing rod is fixedly installed on the inner wall of the mixing drum cover. A telescopic frame is provided between the first and second fixing rods on the same side, and the push rods at both ends of the telescopic frame are equipped with sliders that slide in a sliding fit with the fixing rods. The transmission mechanism includes… The system includes a first pin, a directional push shaft, a rocker arm, a base, a telescopic rod, and a motor. The first pin and the directional push shaft are both located on both sides of the mixing drum. The shaft portion of the telescopic frame facing the drum cover is movably connected to the first pin. The first pin is fixedly connected to the directional push shaft on the same side, and the directional push shaft is slidably engaged with the drum cover. The base is located on both sides of the mixing drum. The rocker arm is vertically rotatably mounted on the base. A vertical elongated hole is provided at the top of the rocker arm. A second pin is provided on the directional push shaft, passing through the elongated hole and slidably engaged with the rocker arm. The telescopic rod passes through a bracket and is rotatably connected between the rocker arms. An ear plate is provided on one side of the base, and a crank is rotatably mounted on the ear plate. A connecting rod is rotatably mounted between the crank and the end of the telescopic rod. The motor is connected to the crank to drive the crank to rotate circumferentially.

[0006] Furthermore, the piston has three grooves in the circumferential direction, and each groove is provided with a sealing ring.

[0007] Furthermore, the flow holes on the filter plate are distributed in concentric rings, and liquid channels are provided between the flow holes in the same ring and adjacent rings inside the filter plate. The piston is provided with protrusions corresponding to each flow hole on the filter plate. The protrusions on the left and right sides of the same flow hole can be inserted into the flow hole, and there is a gap between the protrusion and the flow hole.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This invention allows the two pistons inside the mixing drum to move synchronously, thereby causing a synchronized change in the space between the pistons and the sides of the filter plate. This facilitates the mixing of paint between the pistons through the flow holes on both sides of the filter plate, creating turbulent flow that is more adaptable to various paint compositions. Furthermore, the movement of the pistons on both sides of the mixing drum can be controlled by a transmission structure, saving manpower and increasing mixing efficiency. The mixed paint can be completely released and any remaining paint in the drum can be squeezed out, saving material costs and avoiding waste. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 5 As shown, a drum-type paint mixing device includes a mixing drum 1 and a transmission mechanism 5. The bottom of the mixing drum 1 is supported by brackets 4 at both ends. A filter plate 7 is installed on the inner wall of the middle section of the mixing drum 1, and paint inlets 2 and outlets 3 are respectively installed on the outer wall of the middle section of the mixing drum 1. Flow holes 8 are evenly distributed on the filter plate 7, and each inlet 2 and outlet 3 communicates with an adjacent flow hole 8. Inside the mixing drum 1, pistons 6 are respectively installed on both sides of the filter plate 7, which are in a sealing and sliding fit with the inner wall of the mixing drum 1. A first fixing rod 9 is fixedly installed on the side of the piston 6 facing the drum cover of the mixing drum 1, and a second fixing rod 10 is fixedly installed on the inner wall of the drum cover of the mixing drum 1. A telescopic frame 11 is installed between the first fixing rod 9 and the second fixing rod 10 on the same side. The push rods at both ends of the telescopic frame 11 are equipped with sliders 12 that slide in a sliding fit with the fixing rods. The transmission mechanism 5 includes a first pin 51, a directional push rod, and a sliding block 12. The mixing drum 1 is equipped with a shaft 52, a rocker arm 54, a base 55, a telescopic rod 56, and a motor. A first pin 51 and a directional push shaft 52 are both located on both sides of the mixing drum 1. The shaft portion of the telescopic frame 11 facing the drum cover is movably connected to the first pin 51. The first pin 51 is fixedly connected to the directional push shaft 52 on the same side, and the directional push shaft 52 slides against the drum cover. The base 55 is located on both sides of the mixing drum 1. The rocker arm 54 is vertically rotatably mounted on the base 55. A vertical elongated hole is provided at the top of the rocker arm 54. A second pin 53, which passes through the elongated hole and slides against the rocker arm 54, is provided on the directional push shaft 52. The telescopic rod 56 passes through the bracket 4 and is rotatably connected between the rocker arms 54. An ear plate is provided on one side of the base 55, and a crank 57 is rotatably mounted on the ear plate. A connecting rod 58 is rotatably mounted 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.

[0020] like Figure 2 and Figure 3 As shown, during mixing, paint is injected into the mixing drum 1 through inlet 2, and released through outlet 3 after mixing is complete. The telescopic rod 56 is set to a fixed length, and the transmission mechanism is responsible for synchronizing the displacement of the two pistons. The motor drives the crank 57 to rotate circumferentially, which in turn pulls the connecting rod 58, which in turn pulls the rocker arm 54 to swing left and right. When the connecting rod 58 pulls one rocker arm 54 to swing left and right, the other rocker arm swings left and right synchronously due to the traction of the telescopic rod 56.

[0021] When both joysticks 54 swing to the left simultaneously:

[0022] The movement of the left transmission mechanism is as follows: the rocker arm 54 pulls the directional push shaft 52 toward the outside of the cylinder, and at the same time the first pin shaft 51 is also pulled toward the cylinder cover, causing the telescopic frame 11 to be pulled back and retracted. The sliders 12 on the first fixed rod 9 and the second fixed rod 10 are lengthened due to the retraction 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 both fixedly connected to the piston 9 and the cylinder cover respectively through the ear plate, the piston 9 located on the left moves toward the cylinder cover, expanding the space between the left piston 9 and the filter plate 7.

[0023] The movement of the right-side transmission mechanism is as follows: the rocker arm 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, causing the telescopic frame 11 to be pushed to extend. 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 also increases. Since the first fixed rod 9 and the second fixed rod 10 are both fixedly connected to the piston 9 and the cylinder cover respectively through the ear plate, the piston 9 on the right side moves toward the filter plate 7, reducing the space between the right piston 9 and the filter plate 7.

[0024] When both rocker arms 54 swing to the right simultaneously: the left transmission mechanism and the right transmission mechanism move in opposite directions as described above, causing the left piston 9 to move toward the filter plate 7, reducing the space between the left piston 9 and the filter plate 7, and causing the right piston 9 to move toward the cylinder cover, expanding the space between the right piston 9 and the filter plate 7.

[0025] The two pistons 6 inside the mixing drum 1 move synchronously, so that the size of the space between the filter plate 7 and the pistons 6 changes synchronously. Due to the repeated squeezing of the two pistons 6, the paint flows through both sides of the filter plate 7, causing the paint between the pistons 6 to flow and mix through the flow holes 8 on both sides of the filter plate 7, forming turbulence. This makes it easier to adapt to the components of various paints, saves manpower, and has high mixing efficiency.

[0026] The piston 6 has three grooves in its circumference, and each groove is equipped with a sealing ring 62 to form a sealed fit between the piston 6 and the inner wall of the mixing cylinder 1, thus preventing paint leakage.

[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 rocker arms 54 are pulled to swing toward the mixing drum 1, thereby driving the two pistons 6 to move toward the filter plate 7, squeezing the mixed paint toward the filter plate 7 until the protrusions 61 on the two pistons 6 are inserted into the flow hole 8 and abut against each other, so that all the paint flows out from the outlet 3.

[0028] like Figure 4 and Figure 5As shown, the flow holes 8 on the filter plate 7 are distributed in concentric rings. Liquid channels 13 are provided inside the filter plate 7 between the flow holes 8 in the same and adjacent rings. The piston 6 is provided with protrusions 61 corresponding to each flow hole 8 on the filter plate 7. The protrusions 61 located on the left and right sides of the same flow hole 8 can be inserted into the flow hole 8, with a gap between the protrusion 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 channels 13 between the flow holes 8 can squeeze all the paint remaining in the flow hole 8 outwards after the protrusion 61 is inserted into the flow hole 8. The paint flows downwards through the liquid channels 13 into the flow hole 8 connected to the outlet 3, and is finally released from the outlet 3. This design saves material costs, avoids waste, and facilitates subsequent cleaning of the cylinder.

[0029] The outer wall of the middle section of the mixing drum 1 is a regular polygonal structure. Both the inlet 2 and the outlet 3 are located on the plane of the outer wall of the middle section of the mixing drum 1. The inlet 2 is located in the upper half of the mixing drum 1, and the outlet 3 is located in the lower half. The regular polygonal design of the middle section of the mixing drum 1 provides planar positions for the inlet 2 and outlet 3, facilitating their installation. The location of the inlet 2 in the upper half and the outlet 3 in the lower half also facilitates the injection and release of paint.

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