Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, specifically a cooling device for plastic drawing of lens raw materials. Background Technology

[0002] Plastics are polymers made from monomers through addition or condensation polymerization. Commonly known as plastics or resins, their composition and shape can be freely altered. They consist of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastics are widely used in the manufacture of lenses.

[0003] Plastic filament drawing involves using a filament drawing machine to pull molten granular raw materials into strips. Typically, the drawn plastic strips need to be transported to a cooling device for cooling. Current technologies mostly utilize cooling tanks, where the plastic strips are submerged below the water surface for cooling. However, because the molding and cooling temperatures of different types of lens plastic materials vary significantly, the above method cannot effectively change the cooling temperature. Therefore, further improvements are needed. Utility Model Content

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Example 1: See Figures 1-6 In this embodiment of the invention, a cooling device for plastic raw material for lenses includes a cooling base 1. A water-cooled box 10 is installed on one side of the upper end of the cooling base 1. The water-cooled box 10 is filled with water. An L-shaped frame 6 is symmetrically installed on the upper end of the water-cooled box 10. An adjusting cylinder 7 is installed between the L-shaped frames 6. A movable rod 23 is symmetrically hinged to the bottom of the adjusting cylinder 7. A movable frame 24 is fixedly installed at the end of the movable rod 23 away from the adjusting cylinder 7. An immersion roller 25 is rotatably installed between the movable frames 24. An adjusting mechanism for changing the position of the immersion roller 25 is provided inside the adjusting cylinder 7. Water-cooled rollers 4 are symmetrically installed on both sides of the upper end of the water-cooled box 10. An air-cooled roller 5 is installed on the side of the upper end of the cooling base 1 away from the water-cooled box 10. The strip-shaped plastic produced by the drawing machine is conveyed by one of the water-cooled rollers 4, then passes through two immersion rollers 25, then through another water-cooled roller 4, and finally exited by the air-cooled roller 5.

[0030] The device also includes a circulation mechanism installed on the cooling base 1. The circulation mechanism includes a water-cooled pipe 16 installed inside the water-cooled box 10 and an air-cooled pipe 17 installed inside the air-cooled frame 9. The air-cooled pipe 17 and the water-cooled pipe 16 are internally connected. Refrigerant flows inside the air-cooled pipe 17 and the water-cooled pipe 16. The refrigerant can be a liquid with a larger specific heat capacity than water. The circulation mechanism also includes a circulation component installed at the bottom of the cooling base 1.

[0031] The circulation component includes a cooling box 14 installed at the bottom of the cooling base 1. The cooling box 14 is equipped with a cooling plate 12. The cooling box 14 is connected to both ends of a water-cooled pipe 16 and an air-cooled pipe 17 through a cooling pipe 13. A cooling pump 11 is also installed on the cooling pipe 13.

[0032] The device is also equipped with an air-cooled frame 9 on the cooling base 1. An air-cooled motor 15 is fixedly installed on the upper end of the air-cooled frame 9. Multiple air-cooled fan blades 26 are connected to the output end of the air-cooled motor 15.

[0033] The refrigerant inside the cooling box 14 is cooled by the cooling element 12. Then, under the action of the cooling pump 11, the refrigerant circulates inside the water-cooled pipe 16 and the air-cooled pipe 17, thereby transferring energy through the water-cooled box 10 and the air-cooled fan blades 26. The air-cooled motor 15 is started, causing multiple air-cooled fan blades 26 to rotate, thereby blowing the cold air from the air-cooled pipe 17 onto the strip of plastic, ultimately achieving the purpose of air cooling.

[0034] The adjustment mechanism in this device includes a screw shaft 18 rotatably installed inside the adjustment cylinder 7. The screw shaft 18 is fitted with an adjustment block 19 inside the adjustment cylinder 7 via a threaded structure. An adjustment frame 20 is symmetrically fixedly installed on the side wall of the adjustment block 19. An adjustment rod 22 is hingedly installed through an adjustment groove 21 that passes through the side wall of the adjustment cylinder 7. The end of the adjustment rod 22 away from the adjustment frame 20 is hingedly installed on a movable rod 23.

[0035] Meanwhile, in order to facilitate the adjustment of the adjustment mechanism, an adjustment motor 8 is also installed on the upper end of the adjustment cylinder 7, and the output end of the adjustment motor 8 is connected to the screw shaft 18.

[0036] Start the adjusting motor 8 to drive the screw shaft 18 to rotate. Then, under the limiting action of the adjusting groove 21, the adjusting block 19 drives the adjusting frame 20 to move up and down. Finally, with the cooperation of the adjusting rod 22 and the movable rod 23, the up and down position of the immersion roller 25 is changed. When it is necessary to increase the immersion length of the strip plastic, the immersion roller 25 is moved up, and vice versa.

[0037] To support the device, support legs 2 are installed at the four corners of the bottom of the cooling base 1. For better control, a control panel 3 is also installed on the side wall of the water-cooled box 10. The control panel 3 is electrically connected to the regulating motor 8, the air-cooled motor 15, the cooling pump 11, and the cooling element 12. To adjust the temperature of the cooling element 12, we only need to change the DC voltage input to it, thus achieving rapid changes in the cooling temperature of the air-cooled pipe 17 and the water-cooled pipe 16.

[0038] Example 2: In another embodiment of the present invention, the difference between this embodiment and the above embodiment is that the water-cooling pipe 16 is a serpentine bend structure and the air-cooling pipe 17 is a spiral pipe structure. By setting the water-cooling pipe 16 and the air-cooling pipe 17 into the above structures, the cooling effect is further guaranteed.

[0039] In summary, this device can be used to produce safety goggles or reading lenses. After further processing, these lenses offer high comfort and eye protection. When using this device, the strips of plastic drawn from the wire drawing machine are first installed... Figure 1The strip of plastic is guided through the water cooling box 10, and then the device is controlled by the control panel 3. The length of the strip of plastic inside the water cooling box 10 is changed by the adjustment mechanism, and the temperature of the cooling chip 12 is controlled at the same time. This causes the circulation mechanism to generate cooling at different temperatures, and finally achieves differentiated cooling of the strip of plastic at different temperatures, thus achieving a dual cooling effect.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
