Description

Technical Field

[0001] The utility model relates to the technical field of contact lens compression molding, in particular to a contact lens compression molding edge material removal device. Background Art

[0002] Compression molding of contact lenses is an efficient and cost-effective production method widely used in the manufacture of soft disposable lenses. This process involves injecting liquid raw materials into a mold, followed by molding, demolding, and hydration to create contact lenses. During the compression molding process, mold trimming is a critical step, directly impacting the final quality and comfort of the lens.

[0003] In the prior art, during the mold edge removal process, a large amount of mold debris is generated by grinding and removing the mold edge with a grinding disc. The existing edge removal device cannot effectively clean and collect the mold debris. Excessive accumulation of debris can easily cause device failure and affect the processing operation.

[0004] Therefore, we propose a contact lens molding edge material removal device to solve the above problems. Utility Model Content

[0011] Preferably, a filter screen is provided in the protective ring, and a retaining groove is provided on the filter screen.

[0012] Preferably, the lower end of the pipeline is connected to a waste box.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. The debris generated by grinding is blocked by the protective ring and falls into the pipe through the filter. The lower end of the pipe is connected to the waste box. The debris falls into the waste box through the pipe for collection, which is convenient for operators to handle and prevents the debris from splashing everywhere and being difficult to clean, causing machine failure.

[0015] 2. After processing, the electric grinding disc rises, and most of the debris falls into the waste box. Some debris is located at the upper end of the retention groove and inside it. By pushing the sliding U-shaped frame, the vacuum cleaner is driven to the upper end of the retention groove, and the pull rod is pulled downward to drive the vacuum cleaner down, sucking in the debris at the upper end of the retention groove and inside it and transmitting it into the dust box through the telescopic bellows for collection.

[0016] To sum up, the utility model uses a protective ring to prevent debris from flying around and being difficult to clean, causing machine failure. Most of the debris is collected in the waste box, and the debris in the retention groove is collected in the dust collection box, which is convenient for the operator to handle later and prevents excessive debris from flying around and causing machine failure, thereby affecting the processing operation.
