[0002] Ultraviolet absorbers are the most widely used type of light stabilizers. According to their structure, they can be divided into salicylates, benzophenones, benzotriazoles, substituted acrylonitriles, triazines, etc. Benzophenones and benzotriazoles are the most widely used in industry. Ultraviolet absorbers refer to a class of substances that can absorb the ultraviolet part of sunlight or fluorescent sources without changing their own structure. They can convert high-energy ultraviolet light energy into heat energy or release non-destructive longer light waves, thereby protecting the substances added with ultraviolet absorbers from ultraviolet damage.

[0003] Existing ultraviolet absorbers are usually placed in large storage tanks. Each time they are taken out, the sealed cover needs to be opened, which makes the process of taking out inconvenient. Air will enter during the process of taking out, which can easily affect the storage of the ultraviolet absorber. In addition, the powdered ultraviolet absorber can easily clog the discharger of the equipment when it is automatically discharged.

[0004] The existing patent (CN209209391U) discloses a packaging device for finished ultraviolet absorbers, including an outer packaging barrel, an inner storage barrel connected to the positioning plate, the outer part of the inner storage barrel is stepped, the upper end of the inner through groove is a cylinder, and the lower end is a truncated cone, a fixed plate is fixedly connected to the outer packaging barrel, a groove is provided in the fixed plate, a guide plate is connected to the groove of the fixed plate through a connecting hinge, the guide plate is located at the lower end of the inner storage barrel, a movable groove is provided on one side of the outer packaging barrel, the depth of the movable groove is equal to the wall thickness of the outer packaging barrel, one side of the guide plate extends out of the movable groove, a spring is provided between the guide plate and the outer packaging barrel, and a sealing cover is provided at the upper end of the outer packaging barrel.

When injecting material, the injection tube can press the elastic tube 3021 so that the elastic tube 3021 is inserted into the feeding tube 309. Therefore, when injecting material, the ultraviolet absorber of the powder will not be released outside the barrel 304.

[0030] The rotary unloading assembly 4 includes an electric push rod A401, a U-shaped rod 402, a gasket 403 and a discharge mechanism 404. Two electric push rods A401 are provided, and the electric push rods A401 are fixed to the inner wall of the sealed light shield 301. Two U-shaped rods 402 are provided, and the ends of the two U-shaped rods 402 that are away from each other are respectively fixed to the output ends of the two electric push rods A401. The gasket 403 is located between the two U-shaped rods 402 and fixed to the two. The upper end of the U-shaped rod 402 is located above the gasket 403. After the electric push rod A401 contracts, the gasket 403 contacts the sealing ring 311 and closes the discharge pipe 310. The discharge mechanism 404 is fixed on the gasket 403 and extends to the inside of the barrel 304.

[0031] The electric push rod A401 can be controlled by an operation panel outside the bottom shell 1. The electric push rod A401 adopts an electro-hydraulic push rod, which can store power when the power is off.

[0032] The discharge mechanism 404 includes a discharge pipe 4041 and a paddle 4042. The discharge pipe 4041 is located in the discharge pipe 310 and fits with its inner wall.

An outlet is provided at one end of the outer cover 201, and a light shielding pad is installed on the outlet. Any packaging mechanism 206 can be rotated to the outlet to open the outlet.

[0035] The outer circle of the turntable 202 is basically in contact with the inner wall of the outer cover 201, and there is a small gap between the two, which does not affect the rotation of the turntable 202 and can effectively shield the light. The end cap feeder 204 is a tubular structure, and stacks of end caps can be stored inside. Driven by the electromagnetic controller, the end caps can gradually fall onto the material bucket, and the capper 205 is a traditional rotating capping device. After the end cap falls on the material bucket, the capper 205 rotates to fix the two together. The capper 205 can also choose a variety of capping devices such as hydraulic type to adapt to different types of material buckets.

[0036] The outlet is a circular structure that is matched with the size of the packaging mechanism 206. Two shading pads are provided, or one can be provided. When the material taking bucket is extended from the inside of the outer cover 201, the shading pad can be pushed open. When it falls, the shading pad can be closed by gravity.

[0038] The telescopic tube 2061 adopts a pneumatic telescopic device, and can also adopt an electric type, which is a common active telescopic component in existing packaging equipment.

[0039] The gasket 403 is a conical frustum structure, and the upper end of the U-shaped rod 402 is an arc-shaped ball head structure. The gasket 403 can enter the middle of the multiple U-shaped rods 402.

[0040] The U-shaped rod 402 with the ball head structure can hit the U-shaped rod 402 without damaging the U-shaped rod 402 .

[0043] The matching form between the sealing plug 3032 and the feed pipe 309 is similar to the matching form between the gasket 403 and the sealing ring 311, and both can achieve sealing when closed.

[0044] A plurality of universal wheels 5 are installed at the bottom of the bottom shell 1 .

[0045] When in use, start the motor A305, and make the feed tube 309 of the barrel 304 correspond to the elastic injection mechanism 302, and the powdered ultraviolet absorber can be filled into the barrel 304 through the feed tube 309. After filling, rotate the barrel 304 to make the feed tube 309 correspond to the closing mechanism 303, and the closing mechanism 303 can seal the barrel 304. At this time, the ultraviolet absorber inside the barrel 304 can be sealed and light-shielded for preservation. When the ultraviolet absorber needs to be released, extend the electric push rod A401, and the electric push rod A401 can drive the gasket 403 to leave the discharge pipe 310 and the sealing ring 311. At this time, the ultraviolet absorber can flow out from the discharge pipe 310 and the discharge pipe 4041. If there is a flow blockage problem, the motor A305 can be rotated. At this time, the barrel 304 can be relatively lowered. The material tube 4041 rotates, and the discharge tube 4041 drives the paddle 4042 to stir the ultraviolet absorber inside the material barrel 304, so that the powdered ultraviolet absorber can be discharged more smoothly. The existing material barrel is placed on the tray 2063 and is between multiple limiting levers 2064. When the turntable 202 rotates to drive the material barrel to rotate corresponding to the discharge tube 310, the telescopic tube 2061 extends to send the material barrel into the sealed light shielding cover 301. At this time, the electric push rod A401 extends, and the gasket 403 will extend into the material barrel. After the discharge is about to be completed, the turntable 202 is slightly moved, and the limiting lever 2064 will collide with the U-shaped rod 402. At this time, the powder on the edge of the gasket 403 will fall into the material barrel. The material barrel that has been discharged can be put on the end cover by the end cover discharger 204 and sealed by the capping device 205.
