Description
The technical field is as follows:
the utility model relates to a contact lens production facility, concretely relates to contact lens bat seal discharging device.
Background art:
in the production process of colored contact lenses, pattern printing is the most important process, and the process directly determines the market prospect of the product. There are many methods for printing patterns on contact lenses, and the most common method is a pad printing process, i.e. a pattern layer is obtained by printing a pattern to be printed and a prepared ink on a contact lens mold through a pad printing tool, and then the pattern is cured and molded through a thermal curing or light curing process to form a part of the contact lens.
The feeding and discharging of the pattern bearing object, namely the mold, is particularly critical because the printing steps of the patterns are complex and one pattern is required to be printed, and if the feeding and discharging speed and the channel are unreasonably set, the mold is easy to fall off or the machine is easy to break down, so that the production efficiency is influenced. Under the circumstances, a need exists for a contact lens pad printing discharging device, so that the falling of a mold is avoided, and the production efficiency is effectively ensured.
The invention content is as follows:
an object of the utility model is to provide a contact lens bat printing discharging device aims at improving production efficiency. The specific technical scheme is as follows:
a contact lens pad printing outfeed device comprising: the device comprises a conveying chain, a die hole, a first sensor, a second sensor and a dragging mechanism, wherein the die hole is positioned on a chain plate of each chain link of the conveying chain; the conveying chain rotates in the vertical surface;
the diameter of the die hole is larger than the diameter of the convex surface of the die and smaller than the diameter of the bottom of the die.
The beneficial effects of the utility model reside in that: the utility model discloses in bat printing ejection of compact pavement can effectively prevent that the mould from dropping to production efficiency can effectively be guaranteed.
Description of the drawings:
FIG. 1 is a schematic view of an embodiment of the present invention; in the figure, 1 denotes a die hole, 2 denotes a first sensor, 3 denotes a shutter, 4 denotes a second sensor, 5 denotes a horizontal telescopic mechanism of a drag mechanism, and 6 denotes a vertical telescopic mechanism of the drag mechanism.
FIG. 2 is a schematic top view of the structure of FIG. 1; in the figure, 1 denotes a die hole, 2 denotes a first sensor, 3 denotes a shutter, 4 denotes a second sensor, and 11 denotes a die hole.
Fig. 3 is a schematic structural diagram of a section of unit of the conveying chain in the embodiment.
FIG. 4 is a schematic diagram of the structure of the molds on the conveying chain in the embodiment.
The specific implementation mode is as follows:
example (b):
a contact lens pad printing outfeed device comprising: the device comprises a conveying chain, a die hole 1 positioned on a chain plate of each chain link of the conveying chain, a first sensor 2 arranged below a first die hole on the upper surface of the chain, a second sensor 4 arranged right below a penultimate die hole 11, and a dragging mechanism positioned below the conveying chain; the conveying chain rotates in the vertical surface;
the diameter of each die hole is larger than the diameter of the convex surface of the die and smaller than the diameter of the bottom of the die; the dragging mechanism comprises a horizontal telescopic mechanism 5 and a vertical telescopic mechanism 6; and two sides of the conveying chain in the horizontal direction are respectively provided with a baffle.
The working process of the contact lens pad printing discharging device is as follows: grabbing the mould printed with patterns from the previous station to the position of a first mould hole, sensing the mould by a first sensor arranged at the position, and then dragging the chain to rotate a section clockwise by a mechanism to finish mould transmission; when the sensor positioned below the penultimate die hole senses that a die is arranged at the position, the die transfer device transfers all the dies on the chain to the next station, and discharging is finished; then the dragging mechanism rotates the chain clockwise by one section, and the operation is circulated.
Claims (2)
