DETAILED DESCRIPTION

[0018] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a mixing device for ACR resin production of the utility model in conjunction with the accompanying drawings.

[0019] like Figures 1 to 3As shown, a mixing device for ACR resin production of the utility model includes a base 1 for supporting a mixing barrel 2, and the base 1 is arranged at the bottom end of the mixing barrel 2, a feeding channel 11 for filling materials into the mixing barrel 2 is opened at the top end thereof, and a discharge channel 12 for discharging the materials inside the mixing barrel 2 is connected to the side wall at the bottom end thereof, and a valve for opening and closing the discharge channel 12 is arranged. At the same time, a stirring device 4 for mixing and stirring the materials added to the mixing barrel 2 is arranged in the mixing barrel 2, and a motor 3 for driving the stirring device 4 is arranged at the top end of the mixing barrel 2, and the motor 3 is connected to an external power supply. Specifically, the stirring device 4 includes a support shaft 41 rotatably arranged in the mixing barrel 2, and stirring arms 42 are distributed along the axial direction of the support shaft 41. Before stirring the materials, the valve on the discharge channel 12 can be closed first, and then the materials can be added from the feed channel 11 of the mixing barrel 2, and then the motor 3 can be started. The motor 3 can drive the stirring device 4 to stir and mix the materials in the mixing barrel 2. After the materials in the mixing barrel 2 are mixed, the valve on the discharge channel 12 can be opened, and the materials in the mixing barrel 2 can be discharged through the discharge channel 12.

[0020] Preferably, a reciprocating device 5 is provided in the mixing barrel 2, and the motor 3 is connected to the stirring device 4 through the reciprocating device 5. When the motor 3 drives the stirring device 4 to work through the reciprocating device 5, the stirring device 4 can not only rotate on its own, but also reciprocate up and down in the mixing barrel under the action of the reciprocating device 5, so as to accelerate the mixing efficiency of the materials in the mixing barrel 2 and make the materials mixed more evenly. Specifically, the reciprocating device 5 includes a cross shaft 56 provided at the output end of the motor 3, the cross shaft 56 passes through the mixing barrel 2, and a hole for the cross shaft 56 to pass through is opened on the top of the mixing barrel 2, and the cross shaft 56 can rotate in the hole. Among them, the support shaft 41 on the stirring device 4 is arranged to slide with the cross shaft 56, and a cross groove 6 for the cross shaft 56 to slide is opened in the support shaft 41 along its axial direction. As shown Figure 2 As shown, a fixing rod 51 is also provided on the top surface of the mixing barrel 2, and a connecting platform 52 is provided at the bottom end of the fixing rod 51. In order to improve the stability of the connecting platform 52 on the fixing rod 51, two connecting platforms 52 are symmetrically provided on the fixing rod 51 with the center of the hole. A cross shaft 56 connected to the output end of the motor 3 passes through the connecting platform 52 and is rotatably arranged thereon. A plurality of protrusions 53 are also distributed around the center of the connecting platform 52 on the top surface. A fixing plate 57 is also provided at the top of the support shaft 41, and connecting plates 54 are symmetrically provided on the fixing plate 57 with the center thereof, and rollers 55 are rotatably provided on the inner walls of the top ends of the two connecting plates 54, and the rollers 55 cooperate with the protrusions 53 on the connecting platform 52.

[0021] Specifically, when the motor 3 rotates, the support shaft 41 is driven to rotate through the cross shaft 56, and the support shaft 41 drives the stirring arm 42 connected thereto to rotate around the axis of the support shaft 41, and the material in the mixing barrel 2 is stirred and mixed through the stirring arm 42. When the support shaft 41 rotates, the fixed plate 57 arranged at the top of the support shaft 41 will also rotate accordingly, and drive the connecting plate 54 arranged thereon to rotate. At this time, the roller 55 arranged on the connecting plate 54 will contact the protrusion 53 on the connecting platform 52 in sequence, and the roller 55 will first move upward along the contour of the protrusion 53 when it contacts the roller 55, and then move downward along the contour of the protrusion 53 under the dead weight of the stirring device 4, so that the roller 55 can drive the support shaft 41 to reciprocate up and down on the cross shaft 56 through the connecting plate 54 and the fixed plate 57, and achieve the effect that the stirring device 4 can reciprocate up and down with the reciprocating device 5 while rotating itself through the cross shaft 56, so that the material in the mixing barrel 2 can not only be rotated, stirred and mixed by the stirring device 4, but also the stirring device 4 can achieve the effect of flipping the material up and down, thereby improving the mixing efficiency of the material in the mixing barrel 2.

[0022] In order to facilitate the stirring device 4 to move upward more smoothly through the reciprocating device 5, a spring 7 is provided in the cross groove 6. In this way, when the roller 55 moves upward with the protrusion 53, the roller 55 moves upward through the connecting plate 54 and the support shaft 41, and compresses the spring 7 between the support shaft 41 and the cross shaft 56. After that, the roller 55 continues to rotate, and the support shaft 41 drives the roller 55 to move downward through the fixing plate 57 and the connecting plate 54, and the spring 7 provided in the cross groove 6 will also stretch, and push the support shaft 41 to move downward under the action of the cross shaft 56, so that the roller 55 and the protrusion 53 can work more stably.

[0023] As another preferred embodiment, a support arm 8 is provided on the cross shaft 56 below the connecting platform 52, and the support arm 8 is arranged perpendicular to the axis of the cross shaft 56, and a stirring rod 9 is provided at the free end of the support arm 8 and is parallel to the axis of the support shaft 41. When the motor 3 drives the cross shaft 56 to work, the support arm 8 connected to the cross shaft 56 will also rotate, and drive the stirring rod 9 on the support arm 8 to rotate around the center of the cross shaft 56, so that the stirring rod 9 can stir the material close to the inner wall of the mixing barrel 2, effectively improving the mixing efficiency of the materials inside the mixing barrel 2. At the same time, the support arm 8 arranged on the cross shaft 56 is arranged symmetrically with respect to the center of the cross shaft 56, which can further improve the stirring efficiency of the materials in the mixing barrel 2.

[0024] like Figure 3As shown, a plurality of flaps 10 are obliquely distributed on the stirring rod 9, and the clockwise end of the flap 10 is arranged lower than the counterclockwise end thereof. When working, the stirring rod 9 drives the flap 10 to rotate around the axis of the cross shaft 56, and the flap 10 will flip the material in the mixing barrel 2 upward, and collide with the material part in the process of the stirring device 4 stirring the material up and down, so that the material in the mixing barrel 2 is mixed more quickly and evenly.

[0025] Usage: Close the valve on the discharge channel 12, then add the material into the mixing barrel 2 through the feed channel, start the motor 3, and the motor 3 drives the stirring device 4 to work through the reciprocating device 5, so that the stirring device 4 moves up and down to stir and mix the material in the mixing barrel 2, and at the same time, the stirring rod 9 set on the cross shaft 56 through the support arm 8 will also rotate around the cross shaft 56, and stir the material in the mixing barrel 2, thereby accelerating the stirring efficiency of the material in the mixing barrel 2. At the same time, the flap 10 set on the stirring rod 9 will also rotate around the center of the cross shaft 56, and flip the material in the mixing barrel 2 upward, thereby accelerating the stirring and mixing efficiency of the material in the mixing barrel 2 again.
