Description

Technical Field

[0001] This utility model relates to the field of polyethylene wax screening technology, specifically a polyethylene wax inspection and screening device. Background Technology

[0002] Polyethylene wax is a low molecular weight polyethylene with excellent chemical stability, thermal stability, lubricity, and dispersibility. As an additive, polyethylene wax can be directly added to polyolefin processing to increase the gloss and processing performance of products. Compared with other external lubricants, polyethylene wax has a stronger internal lubrication effect for PVC.

[0003] The spherical polyethylene wax particle screening device disclosed in CN 220428948 U has a collection basket for holding spherical polyethylene wax particles on a support below the screening basket. The upper part of the collection basket is funnel-shaped, and the bottom of the collection basket is connected to a discharge pipe. A discharge control valve is installed on the discharge pipe.

[0004] This spherical polyethylene wax particle screening device uses a power device to drive the screening basket to rotate up and down, which can screen spherical polyethylene wax particles. However, when the screening basket rotates up and down and shakes, the polyethylene wax particles inside the screening basket are easily shaken off and fall, resulting in material waste. Therefore, it needs to be improved. Utility Model Content

[0018] 2. This polyethylene wax inspection and screening device uses a drive motor to rotate a threaded rod, causing the threaded plate to move on the threaded rod. This, in turn, causes the collection box to slide inside the bottom of the screening barrel, making it easy to collect the screened polyethylene wax. This eliminates the need for frequent manual operation and saves labor costs. Attached Figure Description

Through the fixed groove, the rotating gear 414 can drive the outer gear disk 412 to rotate when it rotates.

[0035] Example 2

[0036] Please see Figure 1-5 Furthermore, based on Embodiment 1, the combing assembly 42 further includes a linkage gear 427, which meshes with the right side of the rotating gear 414. A linkage rod 426 is fixedly connected to the inner side of the linkage gear 427. The bottom of the linkage rod 426 is rotatably connected to the top right side of the support plate 417. An L-shaped plate 424 is rotatably connected to the top of the linkage rod 426. The L-shaped plate 424 is fixedly connected to the top right side of the fixing plate 413.

[0038] Example 3

[0039] Please see Figure 1-5 Furthermore, based on Embodiment 1, the collection mechanism 2 further includes an arc-shaped plate 22, which is fixedly connected to the front and rear sides of the bottom of the load-bearing plate 1. A drive motor 23 is fixedly connected to the back end of the arc-shaped plate 22, and a threaded rod 21 is fixedly connected to the front of the drive motor 23.

The sliding groove can limit the movement of the threaded plate 24, making the threaded plate 24 more stable during movement.

[0041] In actual operation, when this device is used, the polyethylene wax to be screened is put into the screening barrel 3, so that the polyethylene wax can fall to the top of the screening disc 411. The screening motor is turned on, so that the screening motor drives the rotating gear 414 to rotate through the rotating rod 415. The rotating gear 414 drives the screening disc 411 to rotate through the external gear disc 412. The force generated when the screening disc 411 rotates can screen the polyethylene wax. When the rotating gear 414 rotates, it can drive the linkage rod 426 to rotate through the linkage gear 427. The linkage rod 426 drives the gear plate 423 to rotate through the rotating gear 425. The gear plate 423 can drive the combing plate 421 to rotate. The combing plate 421 can rotate in the opposite direction to the screening disc 411. The combing plate 421 can comb the polyethylene wax on the top surface of the screening disc 411, so that the polyethylene wax is less likely to clog the screening disc 411. The polyethylene wax screened by the screening disc 411 falls into the inside of the collection box 25.

[0042] When it is necessary to collect the polyethylene wax inside the collection box 25, turn on the drive motor 23 to drive the threaded rod 21 to rotate, so that the threaded rod 21 drives the collection box 25 to move through the threaded plate 24, so that the collection box 25 can slide out from the inside of the screening barrel 3, making it convenient for the staff to collect the polyethylene wax inside the collection box 25, and so that the staff can take the screened polyethylene wax for inspection.
