Description

Technical Field

[0001] This patent relates to contact lens production equipment, specifically to an automatic material dividing device for a contact lens mold shell cutting machine. Background Art

[0002] At present, most contact lens manufacturers have upgraded their processing technology from the traditional semi-molding process to the full-molding process. The contact lenses produced by the full-molding process are formed by pressing the main contact lens materials together with the mold and the membrane shell. After the membrane shells with different luminosities are pressed together with the mold to form the main contact lens materials, the produced contact lenses have different luminosities. This reduces the process of forming different luminosities through turning in the traditional semi-molded contact lens production process, reduces the contact lens production processes and reduces manufacturing costs. At the same time, the stability and comfort of the products are greatly improved compared to contact lenses produced by traditional processes. Fully molded contact lens products are deeply favored by consumers and have broad prospects.

[0003] After the full-molded contact lens membrane shell is injection-molded, the cutting machine will cut 8 contact lens membrane shells from the eight-claw injection molding rod. The operator will collect them manually and pack the 8 membrane shells of different luminosity into different packages according to different luminosity. After marking the luminosity and other related information, they will be used as qualified products in conjunction with the contact lens mold. However, this manual collection method is inefficient and can easily lead to confusion of different membrane shell luminosities due to negligence of the staff, seriously affecting the production efficiency and quality of the membrane shell. Summary of the invention

[0004] The utility model provides an automatic material dividing device for a contact lens mold shell cutting machine, aiming to improve the collection speed and quality of contact lens mold shells, solve the problem of mixed mold shells after mold shell cutting, and improve the production efficiency of contact lens mold shells. The specific technical solution is as follows:

[0005] An automatic material dividing device for a contact lens mold shell cutting machine comprises: a base plate, a support column and a material dividing tube bundle located on the base plate, a fixed plate located on the support column, a rotating mechanism located on the fixed plate, a rotating shaft connected to the rotating mechanism, a rotating disk connecting device connected to the rotating shaft, a flipping disk connected to the rotating disk connecting device, and N film shell supporting shafts located on the flipping disk;

[0006] The working surface above the membrane shell support shaft is a concave surface, which has the same external geometric features as the convex surface of the membrane shell after cutting. After cutting, the mold shell and the support shaft are lightly embedded together; the material distribution tube bundle is composed of N hollow tubes with smooth inner and outer surfaces. The upper vertical opening is used to receive the membrane shell, and the lower curve extends in N different directions to achieve the separation of membrane shell materials with different light intensities.

[0007] In some embodiments, the invention further comprises: a fixing device, wherein the distribution tube bundle is fixed on the base plate by the fixing device.

[0008] In some embodiments, the value of N is 8.

[0009] In certain embodiments, the diameter of the steel pipe in the distribution pipe bundle is larger than the diameter of the membrane shell support shaft.

[0010] The beneficial effects of the utility model patent are: the automatic material dividing device of the contact lens mold shell cutting machine is reasonably designed, simple and reliable in structure, and can efficiently and accurately separate the cut film shells into different containers, fundamentally solving the problem of manual material dividing and mixing of mold shells; the device adopts a combination design of circular steel pipes and rotating motors, with simple materials and easy manufacturing; by controlling the rotation frequency of the rotating motor and the feeding frequency of the film shell cutting machine, the contact lens film shell dividing process is fully automatic, which greatly reduces the workload of the operators of the fully molded film shell cutting machine, improves the operating efficiency of the fully molded film shell cutting machine, reduces costs, and makes the quality of the fully molded film shells produced more stable.
