[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] The utility model provides a mixing device for modified plastic production, which includes a base plate 1 and a placement groove 2. The placement groove 2 is integrally formed and arranged on the surface of the base plate 1. It mainly solves the problem that the workpiece is inconvenient to take out because it is attached to the inside of the placement groove. If it is picked out by hand or other objects, the surface of the workpiece may be damaged.
[0022] For the device provided by this utility model, please refer to Figures 1-4 , detailed introduction is given below.
[0023] The first movable groove 4 is integrally formed and arranged on the surface of the substrate 1. There are two first movable grooves 4 and they are symmetrically arranged on both sides of the placement groove 2. An elliptical axis 3 is arranged inside the first movable groove 4. A second movable groove 5 is arranged on the bottom surface of the placement groove 2. The second movable groove 5 is connected to the first movable groove 4. A swing rod 7 is arranged inside the second movable groove 5. The other end of the swing rod 7 passes through the first movable groove 4 and fits on the bottom of the elliptical axis 3. The swing rod 7 swings inside the second movable groove 5 through the rotating shaft 8. The two elliptical axes inside the substrate are rotated to make the swing rod tilt upward. The tray at one end of the swing rod extends from the second movable groove to eject the workpiece inside the engaging groove placement groove, so that the workpiece can be easily removed from the substrate. A third movable groove 15 is provided inside the substrate 1. There are two third movable grooves 15 and they are aligned with the two first movable grooves 4 respectively. The third movable groove 15 is set between the first movable grooves 4. There is a circular hole 10, which connects the interior of the first movable groove 4 and the third movable groove 15. A rotating rod 6 is provided on one side of the elliptical axis 3. The rotating rod 6 is movably engaged in the interior of the circular hole 10. One end of the rotating rod 6 extends to the interior of the third movable groove 15. A connecting rod 12 is provided inside the base plate 1. The connecting rod 12 is movably engaged between the two third movable grooves 15. A first bevel gear 13 is provided at one end of the rotating rod 6 close to the third movable groove 15. The first bevel gear 13 is located inside the third movable groove 15. A second bevel gear 14 is fixed on the surface of the connecting rod 12. Two second bevel gears 14 are provided and are respectively located inside the two third movable grooves 15. The second bevel gear 14 is meshed with the first bevel gear 13 for transmission connection. The second bevel gear 14 is used to drive the first bevel gear 13 to rotate, so that the two elliptical axes 3 can rotate synchronously, thereby ensuring that the pendulum of the swing arm 7 can remain consistent.
[0024] For further introduction, a thorn gear 16 is provided inside the base plate 1, and the thorn gear 16 is fixed to the end of the outside of the connecting rod 12 close to the rotating disk 11. A pawl 17 is movably engaged with one end of the thorn gear 16. The pawl 17 is moved through the connecting rod and the return spring, so that the connecting rod 12 can only rotate in one direction, so that the two elliptical axes 3 rotate inward at the same time, and prevent the connecting rod 12 from reversing and causing the two elliptical axes 3 to rotate outward at the same time, resulting in the inability to smoothly press down the swing rod 7.
[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
