Abstract
The utility model relates to a contact lens technical field, concretely relates to contact lens bat seal discharging device. The device comprises: a take-up pan and a die transfer device; the mould conveying device is horizontally arranged, the material receiving disc is obliquely arranged, and the contact lens moulds slide from the top of the disc to the bottom of the disc by virtue of self gravity after entering the material receiving disc and are arranged side by side; the mold conveying device includes: a mold tunnel, a push-pull device; the outlet of the mold channel is connected with the inlet of the receiving disc; the push-pull device can do linear reciprocating motion, and a push rod of the push-pull device pushes the contact lens mold from the inlet to the outlet in the reciprocating process; the mold tunnel is minimally positioned relative to its sides to ensure that the contact lens molds do not deviate from the mold tunnel. The pad printing discharging device is simple in structure, low in failure rate and high in working efficiency, and can effectively improve the production efficiency of the contact lenses.
Description
The technical field is as follows:
the utility model relates to a contact lens technical field, concretely relates to contact lens bat seal discharging device.
Background art:
pad printing is a very important process in the production of colored contact lenses, and the quality of pad printing has a decisive influence on the quality of the final contact lens product. The off-specification of the pad printing process can result in many product failures, such as: chromatic aberration, orange peel, stringiness, breakage, optical zone blur, etc. However, the quality of the pad printing process itself is affected by many factors, such as: temperature, humidity, impurities, etc., among which impurities are one of the more serious factors.
The pad printing is to print the ink on the steel plate on the surface of the mould through a rubber head so as to form a colorful pattern. The printing ink that adopts also is different in the bat printing technology, and the printing ink that some technologies adopted can avoid drying, and the printing ink that can some technologies adopted need carry out solidification treatment and dry, but no matter what kind of printing ink adopts, when the bat printing process has just been accomplished, the printing ink of printing on the mould surface can not be completely dry immediately, so in case be stained with debris or dust on the mould, then can lead to difficult clearance to finally influence the quality of lens. Under the circumstances, it is necessary to provide a contact lens pad printing discharging device which has a reasonable design and high discharging efficiency and can shield impurities or dust, so that the discharging efficiency is improved and the quality of the contact lens can be ensured.
The invention content is as follows:
the utility model aims at providing an automatic contact lens bat printing discharging device.
The specific technical scheme is as follows:
a contact lens pad printing outfeed device comprising: a receiving tray 1 and a mould conveying device 2; the mould conveying device is horizontally arranged, the material receiving disc is obliquely arranged, and the contact lens moulds slide from the top of the disc to the bottom of the disc by virtue of self gravity after entering the material receiving disc and are arranged side by side; the mold conveying device includes: a mold tunnel 24, a push-pull 21; the outlet of the mold channel is connected with the inlet of the receiving disc; the push-pull device can do linear reciprocating motion, and a push rod 22 of the push-pull device pushes the contact lens mould from the inlet to the outlet in the reciprocating process; the mold tunnel is minimally positioned relative to its sides to ensure that the contact lens molds do not deviate from the mold tunnel.
Preferably, the mold transfer device further includes: a cover plate 23 positioned above the push-pull device, the cover plate is fixed on the conveying device through two bolts and is used for shielding sundries and dust; the die transfer device is fixed to the pad printing machine by two hex bolts 25, 26.
And in the second preferred scheme, the material receiving disc is placed on an inclined support frame 3, the support frame is inclined downwards, and the inclination angle is 5-45 degrees.
And in the preferred scheme III, the depth of the receiving disc is 1.2-1.8 times of the height of the die. Furthermore, a transparent plastic plate is arranged on the material receiving disc and is used for preventing sundry dust from falling on the die.
The utility model discloses advantage for prior art is: the utility model discloses in bat printing discharging device simple structure, fault rate are low and work efficiency is high, can effectively improve contact lens's production efficiency.
