Description

Technical Field

[0001] This utility model relates to the technical field of CPP membrane processing equipment, specifically a curing device for CPP membrane production. Background Technology

[0002] CPP film, or cast polypropylene film, is a type of polypropylene film produced through a casting process. It features high transparency, good gloss, and high mechanical strength, and is widely used in food packaging, medical packaging, and other fields. During the production of CPP film, curing equipment is required to eliminate residual stress in the CPP film and improve its stability and performance.

[0003] In the process of using the curing equipment for CPP film production, the CPP film is usually placed on the top of the conveyor belt, and then the drive equipment moves the CPP film through the conveyor belt. When the CPP film passes through the ultraviolet irradiation area, the ultraviolet irradiation lamp emits ultraviolet light of a specific wavelength, which irradiates the surface of the CPP film. The ultraviolet light can trigger the chemical reaction of the photosensitive substances (such as photoinitiators) in the CPP film, promote curing, and thus eliminate the residual stress in the CPP film.

[0004] Existing curing equipment for CPP film production often uses UV lamps in fixed positions, resulting in short contact time between the CPP film and UV light during movement. This leads to inconsistent curing levels and incomplete curing of parts of the CPP film, reducing its quality. To address this, we propose a new curing equipment for CPP film production. Utility Model Content

Through the cooperation of the connecting plate 52 and the adjusting rod 57, the ultraviolet irradiation lamp 54 can be driven to perform a horizontal reciprocating motion, ensuring that all parts of the CPP film surface can be evenly irradiated by ultraviolet rays, thereby achieving a more uniform curing process, reducing curing dead corners, and further increasing the contact time between ultraviolet rays and the CPP film, ensuring the curing effect of the CPP film.

[0023] It also includes a control switch group 2, which is located at the front end of the conveyor frame 1. The input end of the control switch group 2 is electrically connected to an external power supply, and the input end of the ultraviolet irradiation lamp 54 is electrically connected to the output end of the control switch group 2, which can regulate the electrical components inside the equipment.

[0024] Wherein: a vertical rod 6 is rotatably connected to the rear side of the upper end of the partition plate 4. The vertical rod 6 is located to the right of the mounting rod 55. A half gear 7 is provided on the lower side of the outer arc surface of the vertical rod 6. A gear 8 is provided on the lower side of the outer arc surface of the mounting rod 55. The half gear 7 and the gear 8 are installed together. The vertical rod 6 drives the half gear 7 to rotate. When the half gear 7 and the gear 8 are meshed, the gear 8 drives the transmission plate 56 to rotate through the mounting rod 55.

[0025] Among them: a motor 9 is installed on the right side of the top wall of the protective cover 3. The lower end of the output shaft of the motor 9 is fixedly connected to the upper end of the upright 6. The input end of the motor 9 is electrically connected to the output end of the control switch group 2. During the operation of the ultraviolet irradiation lamp 54, the output shaft of the motor 9 drives the upright 6 to rotate, and the upright 6 drives the half gear 7 to rotate.

[0026] The conveyor frame 1 has conveyor rollers 10 rotatably connected to both the left and right sides. The two conveyor rollers 10 are connected by a conveyor belt. A conveyor motor 11 is set on the left side of the front end of the conveyor frame 1. The rear end of the output shaft of the conveyor motor 11 is fixedly connected to the front end of the left conveyor roller 10. The input end of the conveyor motor 11 is electrically connected to the output end of the control switch group 2. By controlling the control switch group 2, the conveyor motor 11 starts to run. The output shaft of the conveyor motor 11 drives the left conveyor roller 10 to rotate. The left conveyor roller 10 drives the right conveyor roller 10 to rotate through the conveyor belt, thereby driving the CPP film to move to the right.

[0027] Among them, springs 12 are respectively provided between the left end of the connecting plate 52 and the left wall of the protective cover 3.

[0028] The working principle of the curing equipment for CPP film production provided by this utility model is as follows: During the use of the curing equipment for CPP film production, the CPP film is first placed on the left side of the upper end of the conveyor belt. Then, by controlling the switch group 2, the conveyor motor 11 starts to run. The output shaft of the conveyor motor 11 drives the left conveyor roller 10 to rotate. The left conveyor roller 10 drives the right conveyor roller 10 to rotate through the conveyor belt, thereby moving the CPP film to the right. When the CPP film moves into the interior of the protective cover 3, by controlling the switch group 2, the ultraviolet irradiation lamp 54 and the motor 9 start to run. During the operation of the ultraviolet irradiation lamp 54, the output shaft of the motor 9 drives the upright rod 6 to rotate. The upright rod 6 drives the half-gear 7 to rotate. When the half-gear 7 and the vertical rod 6 rotate, the vertical rod 6 drives the half-gear 7 to rotate. When gear 8 is engaged, gear 8 drives transmission plate 56 to rotate via mounting rod 55. Transmission plate 56 pushes connecting plate 52 to the left via adjusting rod 57. Spring 12 contracts, and connecting plate 52 drives ultraviolet lamp 54 to the left via fixing plate 53. When half of gear 7 separates from gear 8, the thrust generated by the extension of spring 12 drives connecting plate 52 to move to the right and reset. Connecting plate 52 drives ultraviolet lamp 54 to move to the right and reset via fixing plate 53, thereby driving ultraviolet lamp 54 to perform lateral reciprocating motion. Through the irradiation of ultraviolet lamp 54, the photosensitive material in CPP film is cured, and CPP film is quickly shaped, thereby eliminating residual stress in CPP film and improving the stability and performance of CPP film.
