Description
Technical field:
The present invention relates to a kind of cleanings of equipment surface, more particularly to a kind of form suitable for contact lenses to use conveyor belt of baking oven
Cleaning method.
Background technique:
In the traditional processing technology of contact lenses, molding is a vital procedure, and principle is to pass through heating
Or illumination will inject the lens materials in mold from liquid curing into solid-state, so that the eyeglass of fixed shape is formed, the process pair
The quality and qualification rate of contact lens products play the role of conclusive.Wherein solidify the molding of lens materials by heating
Method is referred to as heat cure, and heat cure is compared to cost is relatively low for photocuring, and operation is relatively easy, so most of factories
Family tends to form contact lenses with the method for heat cure.
Although comparatively cost is relatively low for heat cure, easy to operate, process control also receives several factors
It influences, such as: temperature, humidity, conveyer belt, the unstability of these factors, which will lead to heat cure, cannot be fully achieved desired effect
Fruit, so that molding quality is affected, to further affect the qualification rate of entire product.
Thermoforming ovens generally have a high temperature resistant mesh belt, which is usually to be made by glass, and surface applies
One layer of Teflon.After injecting lens materials in concave mold, then convex type mould is pressed into concave mold, then by the set of molds
Part is placed on the conveyer belt, by the conveyer belt delivery mold component enter baking oven tunnel carry out heated baking, play mold at
The effect of type.But it in the process of injection lens materials, in order not to generate bubble, can generally inject slightly more than material requested
Lens materials, these extra lens materials can overflow concave mold, and a part can be attached to the bottom of concave mold, work as mold
When component is run in baking oven tunnel with conveyer belt, these extra lens materials will be adhered on conveyer belt.Long and
Long it, the lens materials adhered on conveyer belt are more and more, not only will affect the uniformity of temperature in baking oven tunnel, to influence
The molding effect of eyeglass, and the planarization of conveyer belt upper and lower surface can be destroyed, it is put not on the one hand will lead to die assembly
Steadily, influence normally to produce, on the other hand will affect the normal operation of conveyer belt itself, in addition block it is motionless, so as to cause setting
Standby failure, further influences production.
To solve the above-mentioned problems, it is necessary to periodic cleaning, or periodic replacement conveyer belt are carried out to the mesh belt,
Or directly replace the material or pattern of conveyer belt.But due to having sticked cured lens materials on the conveyer belt, so that its
The interface of junction is not available, and leads to not remove cleaning, can damage conveyer belt if tearing open firmly, so generally using work
Tool is directly cleared up on baking oven, but if method for cleaning is improper, is just easy to cause to damage to conveyer belt, or even can damage
Bad baking oven, but also cleaning effect is not achieved.It will increase extra cost if replacing conveyer belt, and cleaning can not be saved
Trouble.In this case it is necessary to a kind of low in cost, easy to operate, effective cleaning method is provided, it can not only
It is enough to clean up conveyer belt, so that equipment operation is more smoothly, and any damage will not be caused to conveyer belt, extend equipment
Service life.
Summary of the invention:
The purpose of the present invention is to provide a kind of using poly hydroxy ethyl acrylate HEMA as the molding of the contact lenses of material
With conveyor belt of baking oven cleaning method, it is intended to be cleaned up in the case where not causing any damage to conveyer belt.Particular technique
Scheme is as follows:
A kind of contact lenses molding conveyor belt of baking oven cleaning method, includes the following steps:
Step 1: under room temperature, cleaning adherency cured lens materials on a moving belt with cleaning solution；
Step 2: under room temperature, with pure water cleaning conveyer belt；
Step 3: drying conveyor；
The cleaning solution can be any one of N,N-dimethylformamide, dimethyl sulfoxide, methanol, ethyl alcohol.
Preferably one, detailed process is as follows for above-mentioned steps 1:
Cleaning solution is injected in antomobile sprayer first；Then the nozzle alignment transmission belt surface of sprayer is located at baking oven
The switch of sprayer is opened in region at tunnel exit, enables the cleaning solution surface fog-like for being sprayed at conveyer belt；It opens
Belt switch is transmitted, it is rotated, rotation direction of the conveyer belt in baking oven tunnel is from baking oven tunnel portal to baking oven tunnel
Road outlet；The velocity of rotation of conveyer belt, one week required time are 2~3 hours.Further it is arranged, it is described automatic in step 1
The pressure of sprayer is 6~7kPa, and discharge rate is 5~8 milliliters per minute；The nozzle of the antomobile sprayer is between conveyer belt
Distance is 0.4~0.6 meter.
Preferably one further setting, detailed process is as follows for step 2: speed of the conveyer belt to be arranged in step 1
Degree keeps rotation, and antomobile sprayer continues to keep sprinkling；When conveyer belt is located at the part outside baking oven tunnel from baking oven tunnel exit
When place turns to baking oven tunnel entrance, giant is opened, and the nozzle of giant is directed at transmission belt surface and is located at baking
It is rinsed in the region of case tunnel entrance back and forth；When conveyer belt be arranged in step 1 speed rotation after a week, close
Antomobile sprayer is closed, and adjusts the velocity of rotation of conveyer belt simultaneously, rotates it required time 8~12 minutes one week；When
Conveyer belt is rotated after a week with speed adjusted, closes giant, while conveyer belt being kept to continue to rotate, velocity of rotation is not
Become, then the conveyer belt in rotation is scrubbed with soft brush；Conveyer belt rotates after a week again, stops scrub, and close biography
Send belt switch.Further it is arranged, in the step 2, the water that the giant sprays is pure water, and pressure is 4~5,000,000
Pa, discharge rate are 3~6 liters per minute.
Preferably two, cleaning solution selects ethyl alcohol；The concrete operations of the step 3 are as follows:
Baking oven switch is opened, is 50~60 DEG C by its temperature setting, and open simultaneously exhaust equipment；Conveyer belt is opened to open
It closes, rotates it, and its velocity of rotation is set, rotate it required time 20~30 minutes one week；Conveyer belt turns
After 1 week dynamic, adjustment oven temperature is 100~120 DEG C；After conveyer belt is rotated further by 1 week, baking oven switch is closed, exhaust equipment is closed,
And transmission belt switch is closed, complete drying operation.Further, the exhaust equipment has two exhaust pipes, is separately fixed at institute
The entrance and exit in baking oven tunnel is stated, pressure is 800~1000Pa, and exhausting amount is 6~10 cubic metres per hour.
The beneficial effects of the present invention are:
(1) cleaning method of the present invention will not cause any damage to conveyer belt, can sufficiently extend conveyer belt
Service life, and compared to replacing for conveyer belt, cost is lower, and does not need commissioning device again, can effectively extend whole
The service life of a equipment.
(2) cleaning method material requested of the present invention and equipment cost are cheap, and wherein cleaning solution and pure water are easy to make
Standby or purchase and cheap, sprayer and giant are widely used and be used multiple times, and exhaust pipe is baking oven institute itself
Band, without re-working installation.
(3) cleaning method of the present invention is easy to operate and process safety, and wherein step 1 and step 3 do not need artificially
Operation, sufficiently saves human cost.
(4) cleaning method significant effect of the present invention can will adhere to cured lens materials on a moving belt and fill
Divide and dissolve and clean up, transmission belt surface on the one hand can be made more smooth, so that equipment operation obtains more smoothly, another party
The uniformity of temperature in baking oven tunnel can be improved in face, to promote the molding effect of eyeglass, and then improve production efficiency and
The qualification rate of product.
