[0030] 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.
[0031] like Figures 1 to 6 As shown, the utility model provides a mixing device for plastic production, comprising:
[0032] A base 1, the upper surface of the base 1 is fixedly connected with a support column 2, and the upper surface of the support column 2 is fixedly connected with a limit plate 3;
[0033] A mixing barrel 4, the outer surface of the mixing barrel 4 is movably connected to the inner surface of the limiting plate 3;
[0034] A power mechanism, which is arranged on the left side of the upper surface of the base 1;
[0035] A vibration mechanism, the vibration mechanism is arranged on the upper surface of the base 1;
[0036] Among them, the vibration mechanism includes a mounting plate 5, the lower surface of the mounting plate 5 is fixedly connected to the upper surface of the base 1, the inner surface of the upper side of the mounting plate 5 is movably sleeved with a fan-shaped plate 6, the left side of the outer surface of the fan-shaped plate 6 is fixedly connected with a driving shaft 7, the front end of the outer surface of the driving shaft 7 is hinged with a connecting rod 8, the other end of the connecting rod 8 is hinged with a connecting plate 9 located below the limiting plate 3, the inner surface of the connecting plate 9 is fixedly connected to the outer surface of the mixing barrel 4, the inner surface of the outer side of the connecting plate 9 is movably sleeved with the outer surface of the support column 2, and the rotation of the driving shaft 7 causes the connecting rod 8 to drive the connecting plate 9 and the mixing barrel 4 to vibrate up and down as a whole.
[0037] When the fan-shaped plate 6 starts to rotate with the upper side of the mounting plate 5 as the axis, the driving shaft 7 will rotate coaxially with the fan-shaped plate 6. In this process, the outer surface of the driving shaft 7 will push the bottom end of the connecting rod 8, so that the connecting rod 8 drives the connecting plate 9 to move upward as a whole. Due to the limitation of the support column 2, the movement of the connecting plate 9 will cause the mixing barrel 4 to vibrate in the vertical direction, causing the plastic attached to the inner wall of the mixing barrel 4 to fall out from the bottom end of the mixing barrel 4 due to the vibration.
[0038] The power mechanism includes:
[0039] A push block 10, the push block 10 is movably connected to the outer surface of the push shaft 7, and the outer surfaces of the front and rear sides of the push block 10 are movably connected to the outer surfaces of the sector plate 6 and the connecting rod 8 respectively;
[0040] A No. 1 pneumatic cylinder 11, the right end of which is fixedly connected to the left surface of the push block 10, and the lower end of which is fixedly mounted on the left side of the upper surface of the base 1.
[0041] The operation of the No. 1 pneumatic cylinder 11 will push the push block 10 to move to the right, which makes the inner surface of the push block 10 push the outer surface of the push shaft 7, so that the push shaft 7 and the fan plate 6 begin to rotate with the upper end of the mounting plate 5 as the axis.
[0042] Among them, the bottom end of the mixing barrel 4 is movably connected to a blocking plate 12, the left end of the blocking plate 12 is fixedly connected to a No. 2 pneumatic cylinder 13, and the outer surface of the No. 2 pneumatic cylinder 13 is fixedly connected to the outer surface of the lower end of the mixing barrel 4.
[0043] When the No. 2 pneumatic cylinder 13 is in operation, the blocking plate 12 will move left and right, thereby sealing and discharging the inside of the mixing barrel 4.
[0044] Among them, the outer surface of the support column 2 is movably sleeved with a spring 14, the upper end of the spring 14 is fixedly connected to the lower surface of the connecting plate 9, the lower end of the spring 14 is fixedly connected to the upper surface of the base 1, and a heater 18 is fixedly installed inside the mixing barrel 4.
[0045] The spring 14 helps the mixing barrel 4 to reset, and the heater 18 heats the inside of the mixing barrel 4 to speed up the mixing efficiency of various plastic materials in the mixing barrel 4 .
[0046] Among them, a motor 15 is fixedly installed on the upper surface of the mixing barrel 4, and a stirring shaft 16 is fixedly sleeved on the other end of the output shaft of the motor 15. The bottom end of the stirring shaft 16 passes through the upper surface of the mixing barrel 4 and extends to the bottom end inside the mixing barrel 4 and is fixedly sleeved with a stirring plate 17.
[0047] When the motor 15 is running, the stirring shaft 16 will rotate and drive the stirring plate 17 to mix the plastic material in the mixing barrel 4.
[0048] Among them, the upper surface of the mixing barrel 4 is fixedly connected to a feed port 19 located on the right rear side of the motor 15, the upper surface of the feed port 19 is fixedly connected to a crushing box 20, the bottom end of the inner surface of the crushing box 20 is fixedly connected to a sliding slope 21, and the inner surface of the crushing box 20 is fixedly connected to a material guide plate 22 located above the sliding slope 21.
[0049] The design of the guide plates 22 allows the materials put into the crushing box 20 to be concentrated between the guide plates 22, which facilitates the subsequent centralized crushing of the plastic particles.
[0050] Among them, the interior of the crushing box 20 is fixedly connected to a fixed roller 23 located below the guide plate 22, and the interior of the crushing box 20 is movably connected to a movable roller 24 located on the right side of the fixed roller 23. The top of the movable roller 24 is movably connected to the inner surface of the crushing box 20, and the inner surface of the bottom end of the movable roller 24 is movably connected to a push rod 25.
[0051] When the movable roller 24 rotates clockwise, the movable roller 24 can crush the plastic particles between the fixed roller 23 and the movable roller 24, thereby improving the mixing efficiency of the plastics.
[0052] A No. 3 pneumatic cylinder 26 is fixedly installed on the right surface of the crushing box 20 , and the other end of the No. 3 pneumatic cylinder 26 penetrates the crushing box 20 and extends to the inside of the crushing box 20 and is hinged to the outer surface of the push rod 25 .
[0053] The operation of the No. 3 air cylinder 26 will cause the push rod 25 to move to the left, and at this time the bottom end of the moving roller 24 will be pushed so that the moving roller 24 starts to rotate clockwise with the upper end of the moving roller 24 as the axis.
[0054] The working principle and use process of this utility model:
[0055] First, the operator puts the plastic particles into the crushing box 20 and starts the No. 3 pneumatic cylinder 26. The operation of the No. 3 pneumatic cylinder 26 will cause the push rod 25 to start moving left and right. At this time, the outer surface of the push rod 25 will drive the bottom end of the mobile roller 24, causing the mobile roller 24 to start periodically rotating repeatedly with the upper end of the mobile roller 24 as the axis. In this process, due to the shapes of the fixed roller 23 and the mobile roller 24, the repeated rotation of the mobile roller 24 crushes the plastic particles located between the fixed roller 23 and the mobile roller 24. The crushed plastic particles will slide into the feed port 19 along the sliding slope 21 and fall into the mixing barrel 4. Then the operator starts the motor 15 and the heater 18. The operation of the heater 18 will heat and melt the plastic mixture inside the mixing barrel 4, thereby accelerating the mixing efficiency of the plastic material. The operation of the motor 15 will cause the stirring shaft 16 to start rotating and drive the stirring plate 17 to stir the plastic particles inside the mixing barrel 4.
[0056] When the material inside the mixing barrel 4 is fully stirred, the operator starts the No. 2 pneumatic cylinder 13 and the No. 1 pneumatic cylinder 11. The operation of the No. 2 pneumatic cylinder 13 will cause the blocking plate 12 to be pulled to the left, which releases the blockage of the blocking plate 12 on the bottom of the mixing barrel 4, so that the material inside the mixing barrel 4 can fall out of the bottom of the mixing barrel 4, and the operation of the No. 1 pneumatic cylinder 11 will cause the push block 10 to move left and right in a short period of time. At this time, the inner surface of the push block 10 will continuously push and pull the outer surface of the push shaft 7, so that the push shaft 7 and the fan plate 6 begin to swing periodically with the upper end of the mounting plate 5 as the axis. In this process, the push shaft 7 will drive the connecting rod 8 so that the top end of the connecting rod 8 continuously pushes and pulls the lower surface of the connecting plate 9, so that the connecting plate 9 as a whole performs periodic vertical vibration under the limit of the support column 2, and the mixed plastic on the inner wall of the mixing barrel 4 will detach from the inner wall of the mixing barrel 4 due to the influence of vibration and fall out of the bottom of the mixing barrel 4.
