Device for preparing regenerated PTFE flitch

Abstract

The invention belongs to the technical field of pressing equipment, and particularly relates to a device for preparing a regenerated PTFE flitch. By arranging a hot pressing plate, a fixed roller unit, a perforated roller unit, an air cylinder unit and an air inlet pipe unit on a bottom plate, the purposes of efficient air cooling and automatic discharging in the PTFE flitch hot pressing process are achieved. The device has the following advantages that firstly, the air cooling and pushing discharging structure for PTFE flitch hot pressing is reasonable and effective, the integration degree of the two functions is high on one structure, the overall structure is compact, stable, simple and efficient, and overall operation is flexible and ingenious; secondly, a driving wheel on the perforated roller unit rotates through wind blowing to drive the hot-pressed plates to be discharged, so that the hot-pressing efficiency can be greatly improved, and the safety of operators is ensured; and thirdly, the air cooling effect is comprehensive after the plate is hot-pressed, targeted air cooling is conducted on the to-be-cooled fixing layer, the air cooling efficiency is high, and energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of pressing equipment, and in particular relates to a device for preparing recycled PTFE laminates. Background technique [0002] Recycled PTFE board refers to a PTFE composite board. In addition to the PTFE substrate, its structure can also have moisture-proof boards, bonded boards, grid boards or elastic protective boards, etc., and the PTFE substrate itself has a high recycling rate. Reuse value, so it can be called recycled board. [0003] The existing preparation process of recycled PTFE laminated boards is relatively simple from the post-processing of the boards, mainly including the two steps of hot pressing and cooling forming. Generally, a simple hot press is used for hot pressing of multi-layer boards, and then Allow to cool naturally. However, there are at least two problems in this existing preparation method: first, the natural cooling rate is slow, which will eventually reduce the overall eff...

Problems solved by technology

However, there are at least two problems in this existing preparation method: first, the natural cooling rate is slow, which will eventually reduce the overall efficiency of the recycled PTFE laminate preparation. If air cooling is required, an additional independent air cooling machine is required. , which is both troublesome and expensive; second, after the heat press machine completes the heat pressing operation, the plate needs to be manually removed and pushed out by the operator, which is very dangerous and inefficient

[0006] However, the thermocompression bonding device in this utility model patent ensures thermocompression bonding and cooling forming operations by introducing a heating chamber and a cooling chamber. Although the effect is good, it greatly increases the cost, volume, and difficulty of use and maintenance of the device. In other words, it is completely unnecessary to set up a cooling chamber, and the contact heat conduction cooling itself is not as direct and efficient as air cooling
