Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm hardening, in particular to a device for hardening diaphragms on product surfaces. Background Art

[0002] UV film usually refers to a film with specific properties that is coated on the surface of a film substrate such as PET, PC, PMMA, or through processes such as UV transfer. A photoinitiator is added to the resin, and after irradiation with ultraviolet light curing equipment, active free radicals or ion radicals are generated, which trigger polymerization, cross-linking and grafting reactions, so that the resin is converted from liquid to solid within seconds, thereby achieving the curing and stable performance of the film.

[0003] During production, after the UV diaphragm is high-pressure molded, it is placed in a curing box and the UV coating on the surface of the diaphragm is cured by a halogen lamp light source. The existing curing box has a simple structure, and the internal placement plate is fixed inside the curing box and cannot be moved, which makes it very troublesome to take and place it, reducing production efficiency. In order to solve the above problems, a device for hardening the diaphragm on the surface of the product is provided. Utility Model Content

DETAILED DESCRIPTION

[0021] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0022] During production, after the UV diaphragm is molded under high pressure, it is placed in a curing box and the UV coating on the surface of the diaphragm is cured by a halogen lamp light source. The existing curing box has a simple structure, and the internal placement plate is fixed inside the curing box and cannot be moved, which makes it very troublesome to take and place it, reducing production efficiency.

[0023] To resolve this issue, see Figures 1-5 , a device for hardening the membrane on the surface of the product, comprising:

[0024] A curing box 1 is provided with a box cover 2, a plurality of halogen lamps 21 are fixedly provided at the bottom of the box cover 2, and a rotating shaft 22 is fixedly provided on the box cover 2 and penetrates the inner wall of the curing box 1;

[0025] The lifting mechanism 3 includes a track 34 and a pair of rotating rods 36. A transmission rod 32 is rotatably provided in the curing box 1. A take-up wheel 322 is fixed on the transmission rod 32. The track 34 is fixedly provided at the bottom of the curing box 1. A slider 342 is slidably provided in the track 34. A pull rope 35 is wound around the take-up wheel 322. The other end of the pull rope 35 is fixedly connected to the slider 342. A pair of rotating rods 36 are located inside the curing box 1. The middle position of the pair of rotating rods 36 is hinged. A placement plate 37 is slidably provided in the curing box 1.

[0026] One end of one of the rotating rods 36 is hinged to the upper end surface of the track 34 close to the transmission rod 32, and the other end is against the lower end surface of the placement plate 37. One end of the other rotating rod 36 is hinged to the lower end surface of the placement plate 37 close to the transmission rod 32, and the other end is hinged to the upper end surface of the slider 342.

[0027] When in use, the transmission rod 32 rotates, and the transmission rod 32 drives the take-up wheel 322 to rotate. The take-up wheel 322 rotates to wrap the pull rope 35 around the take-up wheel 322. The pull rope 35 becomes shorter and pulls the slider 342 to move toward the take-up wheel 322. The slider 342 drives a pair of rotating rods 36 to rotate around the center, lifting the placement plate 37 in a scissors-like manner, driving it to move upward until it moves to the same level as the box opening of the curing box 1 and stops. After placement is completed, the transmission rod 32 is rotated in the opposite direction, and the placement plate 37 falls back into the curing box 1 by gravity. The box cover 2 is closed and the halogen lamp 21 is turned on for curing.

[0028] A motor 31 is fixedly provided in the curing box 1 , a first gear 311 is fixedly provided at the output end of the motor 31 , a second gear 321 is fixedly provided on the transmission rod 32 , and the first gear 311 is meshed with the second gear 321 .

[0029] When in use, the motor 31 is started, the motor 31 drives the first gear 311 to rotate, the first gear 311 drives the second gear 321 to rotate, and the second gear 321 provides rotational power for the transmission rod 32, so that it can complete the lifting of the placement plate 37.

[0030] The curing box 1 is fixedly provided with a round cross bar 33 , and a guide wheel 331 is rotatably provided on the round cross bar 33 .

[0031] During use, the round cross bar 33 provides support for the wire pulley 331. When there is an angle difference between the take-up wheel 322 and the slider 342, the pull rope 35 can be guided so that it can be wound and released smoothly.

[0032] An elastic member 4 is fixedly provided at the bottom of the placement plate 37 , and the end of the elastic member 4 away from the placement plate 37 is fixedly connected to the bottom of the curing box 1 .

[0033] During use, the elastic member 4 is pulled up when the placement plate 37 is raised, and provides a downward pulling force for the placement plate 37 to descend when the placement plate 37 is descended, so that the placement plate 37 will not be stuck due to friction.

[0034] A sector gear 7 is fixedly provided at the bottom of the box cover 2, and the center of the sector gear 7 is horizontal to the axis of the rotating shaft 22. A third gear 5 and a fourth gear 6 that rotate along the axial direction are provided on the inner wall of the curing box 1. The third gear 5 and the fourth gear 6 are meshed with each other, the second gear 321 is meshed with the third gear 5, and the fourth gear 6 is meshed with the sector gear 7.

[0035] During use, when the transmission rod 32 rotates to drive the placement plate 37 to rise or fall, the second gear 321 on the transmission rod 32 drives the third gear 5 to rotate, the third gear 5 drives the fourth gear 6 to rotate, and the fourth gear 6 drives the box cover 2 to rotate around the rotating shaft 22 through the sector gear 7 to complete the opening and closing of the box cover 2. The third gear 5 and the fourth gear 6 are of different sizes. The opening speed of the box cover 2 is adjusted by the third gear 5 and the fourth gear 6 of different sizes, so that when the placement plate 37 is raised to the box opening of the curing box 1, the box cover 2 is just fully opened.

[0036] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed herein are intended to be covered by the claims of the present invention.
