Automatic screw rod cleaning device

Abstract

The invention discloses an automatic screw rod cleaning device. The automatic cleaning device comprises a cleaning frame, a lead screw, a moving worktable and a heating ring, wherein the cleaning frame is used for clamping a screw rod, two ends of the lead screw are mounted on two ends of the cleaning frame, one end of the moving worktable is mounted at the lead screw, and the heating ring is fixedly arranged on the other end of the moving worktable and is penetrated by the screw rod. According to the automatic screw rod cleaning device, the heating ring is utilized for cleaning the screw rod, and the automatic screw rod cleaning device is good in screw rod cleaning effect, high in efficiency, low in energy consumption, use cost and noise and high in security; the operational labor intensity is alleviated, and fused materials are low in pollution so as to be recycled.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a screw automatic cleaning device. Background technique [0002] In the plastics industry, extruders and injection molding machines are widely used. These devices modify or shape plastics through the compression, conveying, shearing and other functions of the screw. When changing the material, the former material will stick to the screw, and the screw needs to be cleaned to avoid contamination of the product. [0003] At present, there are several ways to clean the screw: 1. Rinse with special washing machine material; 2. Use an angle grinder to install a steel wire wheel to grind after preliminary scraping with metal tools; 3. Burn manually with a blowtorch such as liquefied gas. ; 4. Use the oil tank heating method to clean the screw device. [0004] The above are the methods currently in use or existing, which can achieve the function of cleaning, but there are the following disadvantag...

AI Technical Summary

Problems solved by technology

[0004] The above are the methods currently in use or existing, which can achieve the function of cleaning, but there are the following disadvantages: Method 1. The special material is expensive and used for one-time use, so the cost is high; and after the screw is cleaned, it needs to be cleaned at the production site. Clean up used washing materials, which not only increases work intensity, but also risks contamination on site

Method 2. In the cold state of the screw at room temperature, it is difficult to tap the attached plastic shovel, it takes a long time, the labor intensity is high, and the screw is easy to be damaged

At the same time, the wire wheel used for cleaning is consumed quickly and needs to be replaced frequently, which will increase the cleaning cost

Method 3. Working with open flames with hand-held tools has a high safety risk; when the attachments are burned, the smoke and other pollution are relatively large, which is likely to affect human health; it is also easy to reduce the local hardness of the screw due to uneven heating; and the consumption of liquefaction The gas consumption is large, which increases the cleaning cost

Method 4. The heating of the oil tank needs to maintain the oil temperature in the oil tank for a long time, so the energy consumption is very large, and when dealing with long screws (extruder screws can generally reach 2.5 meters and above), a large oil tank is required, so the energy consumption is greater and less expensive. Safe, but it is inconvenient to clean up if the attachment falls in the oil tank
