Description

Technical Field

[0001] The utility model mainly relates to the technical field of screening, and particularly relates to an adaptive stirring and screening device. Background Technique

[0002] Synthetic resin particles are an artificially synthesized high molecular compound. It is a resin product obtained by chemical synthesis from simple organic substances through chemical reactions and has characteristics similar to natural resins. According to different application requirements, the size of resin particles can be adjusted. For example, in the fields of electronic appliances, automobile manufacturing, etc., there are specific requirements for the size of resin particles. By screening, particles of the required size can be obtained to meet the production needs of specific products.

[0003] Application No.: CN202121868439.8, which discloses an adaptive stirring and screening device, including a machine shell and a separation chamber inside the machine shell. The machine shell is provided with a feed inlet and a discharge outlet communicating with the separation chamber. The feed inlet and the discharge outlet are respectively located on opposite end faces of the machine shell. In the utility model, the material to be screened is added into the drum screen through the feed inlet, and the drum screen is driven to rotate by a driving mechanism. The material to be screened is conveyed along the spiral direction of the spiral blade towards the discharge outlet side. The material smaller than the diameter of the sieve holes first drops downward and enters the designated area of the storage drawer. The material larger than the diameter of the sieve holes continues to be conveyed backward on the sieve surface along with the spiral blade. The material sequentially enters different sections with different sieve hole diameters and is screened batch by batch, realizing the separation of materials with multiple diameters, achieving a rapid separation effect of the materials, and improving the separation efficiency of the materials.

[0004] In the above-mentioned prior art, through screening by the first sieve hole, the second sieve hole, and the third sieve hole, the materials can be screened into three specifications according to the diameter range. Similarly, multiple specifications can be screened out to meet different production requirements. However, the screening specifications cannot be selected. In actual production, it is often not necessary to screen out multiple specifications, and only the specifications that meet the production conditions need to be screened out. The materials with redundant specifications need to be re-integrated, which requires additional labor costs. Content of the Utility Model

[0026] Refer to the attached Figures 1-3 , an adaptive stirring and screening device, comprising a base 1, a driving mechanism 2 is arranged on the top of the base 1, a screening drum 3 is connected to the driving mechanism 2, the screening drum 3 is driven by the driving mechanism 2 to rotate along its rotation axis, and an auger blade 6 is arranged on the inner wall;

[0027] The screening cylinder 3 includes a cylindrical screen 31, and the number of the cylindrical screens 31 is multiple. The multiple cylindrical screens 31 are coaxially distributed, and the size of the mesh openings increases successively along the discharge direction of the auger blades 6. Two adjacent cylindrical screens 31 are connected by a connecting cylinder 32, and a movable cylinder 33 is sleeved on the adjacent cylindrical screens 31 and the connecting cylinder 32.

[0028] In this embodiment, after the synthetic resin particles to be screened are placed from one end of the screening cylinder 3, the driving mechanism 2 drives the screening cylinder 3 to rotate, and the auger blades 6 rotate synchronously, so that the synthetic resin particles can be transported to the other end. During the transportation process, they can be screened in sequence through the cylindrical screen 31 with increasing mesh sizes, and the sliding movable cylinder 33 can be sleeved on the cylindrical screen 31 to block its mesh opening, so that cylindrical screens 31 of different specifications can be selected according to production requirements.

[0029] The ends of the adjacent cylindrical screen 31 and the connecting tube 32 are fixedly installed with limit rings 34, and the opposite ends of the two limit rings 34 are provided with annular thread grooves 341, which are matched with the threaded sleeves 35 provided at both ends of the movable tube 33 respectively.

[0030] In this embodiment, the movable cylinder 33 can be locked on the cylindrical screen 31 and the connecting cylinder 32 to complete positioning through the threaded connection of the threaded sleeve 35 and the annular threaded groove 341.

[0031] It should be noted that the locking direction of the threaded sleeve 35 and the annular threaded groove 341 is the same as the direction in which the screening drum 3 is driven to rotate.

[0032] The driving mechanism 2 includes a first driving rod 21 and a second driving rod 22 that are driven to rotate synchronously. The first driving rod 21 and the second driving rod 22 are respectively located on both sides of the screening cylinder 3, and two symmetrically distributed first transmission wheels 23 are fixedly installed on each of them. The two first transmission wheels 23 are respectively in contact with second transmission wheels 24 provided at both ends of the screening cylinder 3.

[0033] In this embodiment, after the first driving rod 21 and the second driving rod 22 are driven to rotate synchronously, the first transmission wheels 23 provided at their ends rotate synchronously, which can drive the second transmission wheels 24 to rotate, thereby driving the screening cylinder 3 to rotate together.

[0034] The driving mechanism 2 further includes a rotating bracket 26 fixedly installed on the top of the base 1. The first driving rod 21 and the second driving rod 22 are rotatably installed on the rotating bracket 26 and are connected by a leather belt 25, and a motor 27 is assembled at the end of one of the driving rods.

The first collection groove 41 is located below the discharge port of the screening cylinder 3, and the plurality of second collection grooves 42 are respectively located below each cylindrical screen 31.

[0037] In this embodiment, the synthetic resin particles screened by the cylindrical screens 31 of different specifications will fall into the corresponding second collection grooves 42, and the synthetic resin particles that are not screened will finally fall from the discharge port of the screening cylinder 3 into the first collection groove 41.

[0038] Collection boxes 5 are inserted into both the first collection groove 41 and the second collection groove 42. Force - borrowing grooves 51 are opened on both opposite inner walls of the collection box 5.

[0039] In this embodiment, after the synthetic resin particles fall into the first collection groove 41 and the second collection groove 42, they are finally collected in the corresponding collection boxes 5, and it is convenient to take them out through the force - borrowing grooves 51 opened on the inner walls of the collection boxes 5.
