TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic product production, and specifically relates to a plastic product screening device. BACKGROUND
[0002] With the wide application of plastic products, the demand for their production has greatly increased. For example, the production of plastic tableware and stationery used in daily life is huge. Traditional manual screening is inefficient and time-consuming, and it is difficult to meet the demand of large-scale production. The screening device can quickly process a large number of plastic products and greatly improve the production efficiency.
[0003] Most of the screening devices currently used are inconvenient for cleaning the plastic debris adhering to the screen plate, discharging the screened plastic products, and repeatedly moving the screen plate for screening. During use, some plastic products may have certain stickiness on the surface. If the plastic debris adhering to the screen plate cannot be cleaned, it will cause the plastic products to block the pores of the screen plate, thereby reducing the passability of the screen plate and causing the screening efficiency of the screen plate to deteriorate. The screening efficiency of the screening device is poor. If the screened plastic products are not discharged from the screening device, it will cause the manual discharge to be more tedious and the cost to be higher, and the convenience of the screening device is poor. If the screen plate is not moved repeatedly for screening, the screen plate needs to be manually vibrated or moved to screen the plastic products, which makes the screening effect poor and the screening efficiency poor, and the practicality of the screening device is poor. The unqualified plastic products falling from the screen plate cannot be buffered. During use, if the unqualified plastic products falling down cannot be buffered, the unqualified plastic products will "run around" after falling down, which makes it difficult for the later workers to collect the unqualified plastic products, and the practicality of the screening device is poor.

[0013] Compared with the prior art, the utility model has the advantages that:
[0014] 1. This utility model, through the design of a cleaning and moving mechanism, achieves the functions of removing plastic debris adhering to the screen plate, facilitating the unloading of screened plastic products, and enabling the screen plate to move and screen more easily. During use, starting the motor drives the scraper to clean the plastic debris adhering to the screen plate and unload the screened plastic products. Then, starting the electric push rod drives the screen plate to move repeatedly for screening. This avoids the plastic products clogging the screen plate's pores due to the inability to remove the plastic debris, thus reducing... The passage of the sieve plate prevents the sieve plate from becoming less efficient, thus ensuring the sieve efficiency of the screening device. It also avoids the situation where it is inconvenient to unload the plastic products screened by the screening device, which would lead to cumbersome and costly manual unloading. This ensures the convenience of the screening device and also avoids the situation where it is inconvenient to repeatedly move the sieve plate for screening, which would require manual vibration or movement to screen the plastic products, resulting in poor screening effect and low screening efficiency. This ensures the screening efficiency of the screening device.
[0015] 2. This utility model, through the setting of a sponge pad, can buffer the unqualified plastic products that fall from the screen. During use, the sponge pad buffers the falling plastic products, which can prevent the unqualified plastic products from "running around" after falling due to the lack of buffering, thus making it inconvenient for the staff to collect the unqualified plastic products later. This ensures the convenience of using the screening device. Attached Figure Description
