[0002] Modified plastics refer to plastic products that are modified on the basis of general-purpose plastics and engineering plastics through filling, blending, reinforcement and other methods to improve their flame retardancy, strength, impact resistance, toughness and other properties. When producing modified plastics, it is usually necessary to mix multiple raw materials before production can begin.

[0003] The Chinese patent "A mixing device for modified plastic production" authorization announcement number "CN215242055U" can use the driving motor on the outer wall of the load-bearing rod to drive the gear plate to rotate through the driving shaft, and then drive the mixing barrel to rotate through the gear ring. Combined with the setting of the stationary fixed axis and spiral fan blades on the inner side of the mixing barrel, the raw materials can be rotated relative to each other between the mixing barrel and the spiral fan blades, thereby achieving the effect of efficient mixing of the raw materials, solving the problem of poor raw material mixing effect of the existing device.

[0004] In the above scheme, the mixing and stirring of the raw materials is achieved by making the mixing barrel and the spiral blades rotate relative to each other, but the spiral blades are fixedly installed and the relative rotation is achieved only by rotating the mixing barrel, which will result in small variability of the raw materials when being stirred in the mixing barrel and poor mixing effect.

[0005] Therefore, a mixing device for modified plastic production is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a mixing device for modified plastic production comprises: a mixing barrel 1, wherein a mixing mechanism 2 is arranged inside the mixing barrel 1; wherein the mixing mechanism 2 comprises a rotating rod 201 rotatably connected to the top end of the mixing barrel 1, the bottom end of the rotating rod 201 penetrates into the interior of the mixing barrel 1 and is hinged with two first stirring rods 203, the surface of the rotating rod 201 is rotatably connected with a vertical rod 204, the surface of the vertical rod 204 is hinged with two second stirring rods 205, the upper surface ends of the rotating rod 201 and the upper surface ends of the vertical rod 204 are fixedly connected with a first bevel gear 206, the top end of the mixing barrel 1 is fixedly connected with a motor 202, the output shaft of the motor 202 is fixedly connected with a second bevel gear 207, the surface of the second bevel gear 207 is meshingly connected with the surfaces of the two first bevel gears 206, and a mixing assembly 208 is arranged on the surface of the rotating rod 201.

[0026] The top of the mixing barrel 1 is provided with a feed port, and the bottom is provided with a discharge port. The first stirring rod 203 and the second stirring rod 205 are in the shape of a half-circle.

[0027] When the production needs to mix the raw materials, the raw materials are put into the mixing barrel 1 through the feed port, and the staff starts the motor 202 in the mixing mechanism 2 through the controller. When the motor 202 is started, it will drive the second bevel gear 207 to rotate, thereby driving the two first bevel gears 206 to rotate in opposite directions. When the two first bevel gears 206 rotate in opposite directions, they will drive the rotating rod 201 and the vertical rod 204 to rotate in opposite directions, so that the rotating rod 201 drives the two first stirring rods 203, and the vertical rod 204 drives the two second stirring rods 205 to rotate in opposite directions to stir the raw materials. At the same time, the mixing component 208 is running.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the mixing assembly 208 includes a mounting ring 2081 slidably connected to the surface of the rotating rod 201, a first hinge rod 2082 is hinged to the inner wall of the first stirring rod 203, and the other end of the first hinge rod 2082 is hinged to the surface of the mounting ring 2081, a trigger ring 2083 is slidably connected to the surface of the vertical rod 204, a second hinge rod 2084 is hinged to the inner wall of the second stirring rod 205, and the other end of the second hinge rod 2084 is hinged to the surface of the trigger ring 2083, and a trigger rod 2085 is fixedly connected to the top of the mounting ring 2081, and the top of the trigger rod 2085 is in contact with the bottom of the trigger ring 2083. The bottom end of the trigger ring 2083 and the top end of the trigger rod 2085 both form an angle with the horizontal plane, and the inclination angle of the bottom end of the trigger ring 2083 is the same as the inclination angle of the top end of the trigger rod 2085.

[0029] When the device is in an initial state, the top of the trigger rod 2085 fits with the highest point of the bottom of the trigger ring 2083 .

[0030] When the rotating rod 201 drives the first stirring rod 203 to rotate, the first hinge rod 2082 will drive the mounting ring 2081 and the trigger rod 2085 to rotate synchronously, and when the vertical rod 204 rotates to drive the second hinge rod 2084 to rotate, the trigger ring 2083 will be driven to rotate synchronously. The rotation path of the trigger rod 2085 and the trigger ring 2083 is the same but the rotation direction is opposite. Under the action of the inclined surface at the bottom end of the trigger ring 2083, when the trigger rod 2085 and the trigger ring 2083 rotate, during the process from the highest point to the lowest point of the top end of the trigger ring 2083 and the bottom end of the trigger ring 2083 contact, the trigger ring 2083 will be squeezed with the trigger rod 2085. At this time, the trigger rod 2085 drives the mounting ring 2081 and the trigger ring 2083 to move away from each other. The trigger ring 2083 will move upward under the action of the trigger rod 2085, and drive the other end of the second hinge rod 2084 to move upward. The angle between the planes will become smaller. At this time, the second hinged rod 2084 will push the second stirring rod 205 to rotate. At the same time, the mounting ring 2081 will drive the other end of the first hinged rod 2082 to move downward under the action of the trigger ring 2083, and the angle between the horizontal planes of the first hinged rod 2082 will become smaller. At this time, the first hinged rod 2082 will push the first stirring rod 203 to rotate. When the trigger rod 2085 and the trigger ring 2083 continue to rotate, the top of the trigger ring 2083 will rotate from the lowest point at the bottom of the trigger ring 2083 to contact with the highest point. At this time, the trigger ring 2083 drives the second hinged rod 2084 to reset, and the mounting ring 2081 drives the first hinged rod 2082 to reset. Therefore, in the process of continuous rotation of the trigger ring 2083 and the trigger rod 2085, the positions of the first hinged rod 2082 and the second hinged rod 2084 change, and the first stirring rod 203 and the second stirring rod 205 will reciprocate.

[0031] The top end of the trigger ring 2083 and the bottom end of the mounting ring 2081 are both fixedly connected to a limiting rod 2087, the surface of the limiting rod 2087 is slidably connected to a cylinder 2086, the surface of the upper cylinder 2086 is fixedly connected to the surface of the vertical rod 204, the surface of the lower cylinder 2086 is fixedly connected to the surface of the rotating rod 201, and a spring 2088 is fixedly connected between the end of the limiting rod 2087 and the inner wall of the cylinder 2086.

[0032] When the trigger rod 2085 and the trigger ring 2083 are squeezed and moved away from each other, the limit rod 2087 will be driven to shrink into the cylinder 2086 and squeeze the spring 2088. In the process that the top end of the trigger ring 2083 rotates from the lowest point of the bottom end of the trigger ring 2083 to contact with the highest point, the trigger rod 2085 and the trigger ring 2083 are reset under the action of the spring 2088 to ensure that the top end of the trigger rod 2085 is close to the bottom end of the trigger ring 2083.

[0033] like Figure 3 As shown, the upper end of the inner wall of the first stirring rod 203 is fixedly connected with a first round rod 2089, and the lower end of the inner wall of the second stirring rod 205 is fixedly connected with a second round rod 20810. The surfaces of the first round rod 2089 and the second stirring rod 205 are fixedly connected with cross bars 209 distributed in equal rows. The first round rod 2089 and the second round rod 20810 are staggered. Since the first stirring rod 203 and the second stirring rod 205 have the same rotation path but opposite rotation directions, when the rotation paths of the first stirring rod 203 and the second stirring rod 205 overlap, the first round rod 2089 and the second round rod 20810 will be staggered. At this time, the staggered cross bars 209 will break up the agglomerated raw materials.

[0034] Since the first stirring rod 203 and the second stirring rod 205 rotate simultaneously, the reciprocating rotation of the first stirring rod 203 and the second stirring rod 205 does not affect the operation of the first round rod 2089 and the second round rod 20810 .

[0035] like Figure 5 As shown, the top of the trigger rod 2085 is rotatably connected with a plurality of balls 2010. The surface of the balls 2010 contacts the bottom end of the trigger ring 2083, and when the bottom end of the trigger ring 2083 moves at the bottom end of the trigger ring 2083, the balls 2010 rotate.

[0036] like Figure 3 As shown, the top end of the mounting ring 2081 is truncated cone-shaped. The top end of the surface of the mounting ring 2081 is an inclined surface.

[0037] When the utility model is used, when mixing materials, the raw materials are put into the mixing barrel 1, the motor 202 is started to drive the second bevel gear 207 to rotate, and under the action of the two first bevel gears 206, the rotating rod 201 drives the first stirring rod 203, and the vertical rod 204 drives the second stirring rod 205 to rotate in opposite directions to mix the raw materials. At the same time, the trigger ring 2083 rotates synchronously with the vertical rod 204, and the trigger rod 2085 rotates synchronously with the rotating rod 201. Under the action of the inclined surface at the bottom end of the trigger ring 2083, when the trigger rod 2085 and the trigger ring 2083 rotate, the trigger ring 2083 and the trigger rod 2085 will reciprocate up and down. When the trigger ring 2083 moves upward under the action of the trigger rod 2085, it drives the other end of the second hinged rod 2084 to move upward and pushes the second stirring rod 205 to rotate. At the same time, the mounting ring 2081 drives the other end of the first hinged rod 2082 to move downward under the action of the trigger ring 2083, and pushes the first stirring rod 203 to rotate. Therefore, the trigger ring 2083 and the trigger rod 2085 are used to reciprocate up and down to make the first stirring rod 203, the first hinged rod 2082 and the second stirring rod 205, and the second hinged rod 2084 mix the raw materials. After the mixture is combined, it can be discharged through the discharge port at the bottom of the mixing barrel 1.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
