DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0021] Please refer to Figures 1-5 A biodegradable plastic article raw material mixing device, comprising a base 1, a mixing cylinder 2 fixedly installed on the top of the base 1, a feeding hopper 3 fixedly communicated with the top of the mixing cylinder 2, a material guide arc plate 4 arranged on the feeding hopper 3, through which the biodegradable plastic raw material can be guided into the mixing cylinder 2, a wire mesh 5 arranged in the mixing cylinder 2, a main motor 6 fixedly installed at one end of the mixing cylinder 2, a drive shaft support 7 fixedly connected to the output end of the main motor 6, a plurality of groups of stirring blades 8 arranged on the outer surface of the drive shaft support 7, the stirring blades 8 being arc-shaped in design, the middle part of which has a larger up-down spacing than the two end parts, cooperating with the design of multiple groups of "rings" on the mixing rack 16, which can increase the stirring range while optimizing the stirring effect, and a crushing and pushing mechanism arranged on the base 1 for accelerating the reaction of the raw material and the catalyst.

[0022] Through the above technical solution, in the use process, small-volume granular biodegradable plastic raw materials (hereinafter referred to as raw materials) can be guided into the feeding hopper 3 through the material guide arc plate 4 and fall into the mixing cylinder 2 through the wire mesh 5, during which the blocky catalyst added to the wire mesh 5 can be crushed by the crushing and pushing mechanism and enter the mixing cylinder 2, cooperating with the stirring of the stirring blades 8 and the pushing of the mixing rack 16, so that the raw materials and the catalyst can fully react to improve the reaction efficiency.

[0023] Specifically, the crushing and pushing mechanism comprises a stand 9 fixedly connected to the base 1, an auxiliary motor 10 fixedly installed on the base 1, and a turntable 11 fixedly connected to the output end of the auxiliary motor 10.

[0024] Through the technical scheme, the guide shaft 12 makes a circular motion in the process of driving the rotating disc 11 to rotate, and the connecting rod 13 and the long connecting frame 20 connected with the guide shaft 12 rotate.

[0025] Specifically, the outer surface of the rotating disc 11 is fixedly connected with the guide shaft 12, the outer surface of the guide shaft 12 is rotatably connected with the connecting rod 13, and the end, away from the guide shaft 12, of the connecting rod 13 is rotatably connected with the inner penetrating shaft 14.

[0026] Through the technical scheme, the part, where the stand 9 intersects with the guide rod frame 15, is partially hollowed out, so that the connecting rod 13 has a certain deflection space. In the deflection process, the connecting rod 13 drives the guide rod frame 15 to move horizontally, and the part, where the guide rod frame 15 and the driving shaft frame 7 pass through the mixing barrel 2, is provided with a sealing ring, so as to ensure the sealing and facilitate the movement of the guide rod frame 15 and the driving shaft frame 7.

[0027] Specifically, the inner surface of the stand 9 is slidably connected with the guide rod frame 15, the inner penetrating shaft 14 is fixedly arranged at the inner side of the guide rod frame 15, and the end, away from the connecting rod 13, of the guide rod frame 15 is fixedly connected with the mixing frame 16, and a plurality of groups of filter holes 17 are formed in the mixing frame 16.

[0028] Through the technical scheme, the mixing frame 16 is provided with three groups of “rings”, the outer diameters of the three groups of “rings” are the same, but the inner diameters are different, the radial thickness or the width of the “rings” at the two ends is larger, and the width of the “ring” in the middle is smaller. This design is to adapt to the stirring blade 8. The upper and lower spacing of the middle part of the arc-shaped stirring blade 8 arranged on the driving shaft frame 7 is larger than that of the two ends (in a rhombus-like design gradually decreasing from the middle to the two ends).

[0029] Specifically, the top of the stand 9 is fixedly arranged with a frame shaft 18, the outer surface of the frame shaft 18 is rotatably connected with a swing arm 19, one end of the swing arm 19 is rotatably connected with a long connecting frame 20, and the bottom end of the long connecting frame 20 is rotatably connected with the outer surface of the guide shaft 12.

[0030] Through the technical scheme, in the process of deflection of the long connecting frame 20 under the action of the guide shaft 12, the long connecting frame 20 pushes and pulls the swing arm 19, so that the swing arm 19 rotates along the frame shaft 18. When the long connecting frame 20 moves downward relatively, the short connecting frame 21 at the other end moves upward relatively, and vice versa.

[0031] Specifically, the end of the swing arm 19 away from the long connecting frame 20 is rotationally connected with the short connecting frame 21, the inner wall of the feeding hopper 3 is slidingly connected with the crushing table 22, the inner side of the crushing table 22 is fixedly provided with the table shaft 23, and the outer surface of the table shaft 23 is rotationally connected with the bottom of the short connecting frame 21.

[0032] Through the above technical scheme, the bottom of the crushing table 22 is designed with sharp nails for crushing the blocky catalyst, and when the crushing table 22 extrudes the blocky catalyst on the wire mesh 5, the blocky catalyst can be torn and broken into smaller particles and pass through the wire mesh 5 into the mixing cylinder 2.

[0033] Working principle: when the device is in use, small volume and particle-shaped raw materials are first introduced into the feeding hopper 3 through the guide arc plate 4 and fall into the mixing cylinder 2 through the wire mesh 5, and the relatively large volume blocky catalyst is added to the feeding hopper 3 and falls onto the wire mesh 5, at which time the auxiliary motor 10 can be started to drive the rotating disc 11 to rotate, and in this process, the guide shaft 12 makes a circular motion and drives the long connecting frame 20 to move back and forth to push and pull the swing arm 19, so that the swing arm 19 rotates along the frame shaft 18, and when the swing arm 19 is pressed down near one end of the long connecting frame 20, the end near the short connecting frame 21 is raised, and vice versa, and in this process, the short connecting frame 21 is driven to drive the crushing table 22 to slide up and down along the feeding hopper 3 (the bottom end of the short connecting frame 21 rotates along the table shaft 23 to push and pull the crushing table 22), so that when the crushing table 22 is extruded during the downward movement, the blocky catalyst on the wire mesh 5 is extruded, and the sharp nails designed on the bottom of the crushing table 22 can tear and break the blocky catalyst with a larger volume into smaller particles, so as to easily pass through the wire mesh 5 into the feeding hopper 3 and mix with the raw materials, the contact area of the small particle catalyst with the raw materials is larger, that is, the activity of the catalyst is more easily fully utilized, and at the same time, the guide shaft 12 drives the connecting rod 13 to deflect during the circular motion, and the two ends of the connecting rod 13 rotate along the guide shaft 12 and the inner penetrating shaft 14, respectively, and the connecting rod 13 drives the driving rod frame 15 to move back and forth through the inner penetrating shaft 14, so that the driving rod frame 15 repeatedly moves transversely to drive the mixing frame 16 to move back and forth to push the mixture of raw materials and catalyst, and the design of the filter hole 17 can allow the material to pass through, thereby reducing the difficulty of pushing the material and improving the mixing effect, and at the same time, the main motor 6 can be started to drive the driving shaft frame 7 to rotate, so that the plurality of arc-shaped stirring blades 8 rotate to stir the material, so that the material is further mixed and uniform, and finally the mixed material can be discharged and collected by opening the discharge valve of the mixing cylinder 2.

[0034] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
