Description

Technical Field

[0001] This invention relates to the field of ultraviolet absorbers, specifically to a packaging device for a finished ultraviolet absorber. Background Technology

[0002] Ultraviolet absorbers are currently 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 are 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 substances with added ultraviolet absorbers from ultraviolet damage.

[0003] Existing UV absorbers are usually stored in large storage tanks, which require opening the sealed lid each time they are retrieved. This process is inconvenient and allows air to enter, which can affect the storage of the UV absorbers. Furthermore, powdered UV absorbers are very likely to clog the discharge device of the equipment when they are automatically discharged.

[0004] Existing patent (CN209209391U) discloses a packaging device for a finished ultraviolet absorber, including an outer packaging barrel. An inner storage barrel is connected to a positioning plate. The outer surface of the inner storage barrel is stepped. The upper end of the inner channel is cylindrical, and the lower end is a frustum. A fixing plate is fixedly connected inside the outer packaging barrel. A groove is formed in the fixing plate. A guide plate is connected to the groove of the fixing plate through a connecting hinge. The guide plate is located at the lower end of the inner storage barrel. A movable groove is formed 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. A sealing cap is provided at the upper end of the outer packaging barrel. In this packaging device for the finished ultraviolet absorber, the lower end of the inner storage barrel is provided with a guide plate supported by a spring. When it is necessary to retrieve the finished ultraviolet absorber, simply press the guide plate downwards, and the finished product inside the inner storage barrel can slide outwards along the guide plate.

[0005] In this scheme, the ultraviolet absorber is tilted to allow it to flow out and then be shut off after rebounding. However, when the ultraviolet absorber is removed and packaged, it will be contaminated due to the lack of proper light protection. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a packaging device for a finished ultraviolet absorber, which solves the problems mentioned in the background section.

After the electric push rod A retracts, the gasket contacts the sealing ring and closes the feeding pipe. The feeding mechanism is fixed on the gasket and extends into the inside of the material barrel.

[0009] Preferably, the discharge mechanism includes a discharge pipe and a paddle. The discharge pipe is located inside the discharge pipe and is attached to its inner wall. A connecting piece is fixedly installed at the bottom of the discharge pipe. The lower end of the connecting piece is fixed to a gasket. The upper end of the discharge pipe is located inside the material barrel. The paddle is located inside the material barrel and is fixed to one side of the upper end of the discharge pipe. When the discharge pipe moves to the lowest point, the paddle contacts the inner bottom wall and side of the material barrel. The side of the feed tube has an opening that extends through both the inside and outside.

[0010] Preferably, the rotary packaging assembly includes an outer cover, a turntable, and a motor B. The outer cover is fixed to the bottom of the sealed light shield, and the two have internal cavities that communicate with each other. The outer cover is fixed to the inside of the bottom shell. The turntable is located inside the bottom end of the outer cover. The motor B is fixed to the inner bottom wall of the bottom shell. The output shaft of the motor B is fixed to the center of the bottom surface of the turntable. An end cap feeder and a capping device are fixedly installed on the outer cover. Multiple packaging mechanisms are also installed on the turntable. The multiple packaging mechanisms are evenly distributed around the turntable. The packaging mechanisms can enter the sealed light shield and correspond to the end cap feeder and the capping device respectively.

[0011] One end of the outer cover is provided with an outlet, and a light-shielding pad is installed on the outlet. The outlet can be opened by rotating any of the sealing mechanisms to the outlet.

[0012] Preferably, the packaging mechanism includes a telescopic tube, a top post, a tray, and a limiting lever. The top post is fixed to the upper surface of the turntable.

[0015] Preferably, the sealing mechanism includes an electric actuator B and a sealing plug. The electric actuator B is fixed to the sealing light shield, and the sealing plug is fixed to the output end of the electric actuator B. The sealing plug is used to seal the upper end of the feed pipe.

[0016] Preferably, the bottom of the base shell is equipped with multiple casters.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The packaging device for the finished ultraviolet absorber is equipped with a material holding component. The feed pipe of the material barrel is aligned with the elastic injection mechanism. Powdered ultraviolet absorber can be added into the material barrel through the feed pipe. After filling, the material barrel is rotated to align the feed pipe with the sealing mechanism. The sealing mechanism can seal the material barrel. At this time, the ultraviolet absorber inside the material barrel can be sealed and protected from light, which can achieve long-term preservation. Moreover, the entire device can be moved to any position at will.

[0018] 2. The packaging device for the finished UV absorber, by setting a rotating feeding component, allows for the release of UV absorber when the electric push rod A is extended. The electric push rod A can drive the gasket away from the discharge pipe and the sealing ring, allowing the UV absorber to flow out from the discharge pipe and the feeding pipe. If flow blockage occurs, the motor A can be rotated, allowing the material barrel to rotate relative to the feeding pipe. The feeding pipe drives the paddle to agitate the UV absorber inside the material barrel, thus making the discharge of the powdered UV absorber smoother. The opening can also be used to clean the discharge pipe, thereby ensuring smooth discharge when discharging powdered UV absorber.

[0019] 3. The packaging device for the finished UV absorber uses a rotating packaging assembly. When the UV absorber is used, the existing feeding bucket is placed on a tray between multiple limiting levers. When the turntable rotates, it causes the feeding bucket to rotate and corresponds to the discharge pipe. The telescopic tube extends, sending the feeding bucket into the sealed light-shielding cover. At this time, the electric push rod A extends, and the gasket extends into the feeding bucket. Just before the feeding is completed, the turntable is slightly moved, and the limiting levers collide with the U-shaped rod. At this time, the powder on the edge of the gasket falls into the feeding bucket. After sealing, the content of UV absorber powder outside the bucket is reduced. During the sampling process, the feeding bucket is always inside the sealed light-shielding cover, even before sealing, which can achieve a good light-shielding effect and avoid the problem of some powder becoming ineffective.

[0020] 4. The packaging device for the finished ultraviolet absorber, by setting an end cap feeder and a capping device, allows the feeding bucket to be placed on the end cap by the end cap feeder and sealed by the capping device. This process is always inside the outer cover, avoiding the problem of light failure. After the capping is completed, the feeding bucket is rotated to the outlet, and the light-shielding pad will be opened as the telescopic tube extends, allowing it to be taken out.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0027] like Figure 1-10 As shown, a packaging device for a finished ultraviolet absorber includes a bottom shell 1, a rotary packaging component 2, a material holding component 3, and a rotary unloading component 4. The rotary packaging component 2 is mounted on the bottom shell 1, and the material holding component 3 is mounted on the rotary packaging component 2.

[0028] The material holding assembly 3 includes a sealing light shield 301, an elastic material injection mechanism 302, a sealing mechanism 303, and a material bucket 304. The sealing light shield 301 is installed on the rotating material feeding assembly 4. The material bucket 304 is located inside the sealing light shield 301. A motor A305 is fixedly installed on the inner top wall of the sealing light shield 301. The output shaft of the motor A305 is fixed to the center position of the top of the material bucket 304. An annular track 306 is provided on the inner wall of the sealing light shield 301. A wheel frame 307 is fixedly fitted on the outer ring of the bottom end of the material bucket 304. A ring of rollers 308 is provided inside the wheel frame 307 and distributed around the outside of the material bucket 304. The rollers 308 are rotatably connected to the wheel frame 307. The outer ring of the rollers 308 away from the wheel frame 307 is located inside the annular track 306. The upper end of the material barrel 304 is provided with a feed pipe 309, which is connected to the inside of the material barrel 304. The upper end of the feed pipe 309 has a trumpet-shaped structure. The sealing mechanism 303 is installed on the sealing light shield 301 and is used to seal the upper end of the feed pipe 309. The elastic injection mechanism 302 includes an elastic tube 3021, which passes through the upper end of the sealing light shield 301 and slides elastically up and down with it. The lower end of the elastic tube 3021 can be inserted into the feed tube 309. A discharge pipe 310 is fixedly installed at the bottom center of the material barrel 304. The discharge pipe 310 is connected to the inside of the material barrel 304. A sealing ring 311 is provided on the bottom outer ring of the discharge pipe 310. The rotating feeding assembly 4 is installed in the sealed light shield 301 and is used to open and close the discharge pipe 310.

[0029] The bottom shell 1 has a hollow interior containing circuit components, while the exterior has an operating panel for controlling the operation of the internal electrical components. The sealed light shield 301 is made of a closed metal cover with a light-shielding coating on the inside; the roller 308 has a shuttle-shaped structure, and the internal shape of the annular track 306 matches the outer circular shape of the shuttle-shaped roller 308. The upper end of the material barrel 304 is provided with a round hole, through which the elastic tube 3021 passes. A spring is installed between the two. When the spring is not under force, the upper end of the elastic tube 3021 protrudes from the round hole. During the injection, the injection tube can press the elastic tube 3021, so that the elastic tube 3021 is inserted into the feed tube 309. Thus, during the injection, the ultraviolet absorber of the powder will not be released outside the material barrel 304.

[0030] The rotary feeding assembly 4 includes an electric push rod A401, a U-shaped rod 402, a gasket 403, and a feeding mechanism 404. There are two electric push rods A401, which are fixed to the inner wall of the sealing light shield 301. There are two U-shaped rods 402, with the ends of the two U-shaped rods 402 that are far apart from each other fixed to the output ends of the two electric push rods A401 respectively. The gasket 403 is located between the two U-shaped rods 402 and is fixed to them. The upper end of the U-shaped rod 402 is above the gasket 403. After the electric push rod A401 retracts, the gasket 403 contacts the sealing ring 311 and closes the feeding pipe 310. The feeding mechanism 404 is fixed on the gasket 403 and extends into the inside of the material bucket 304.

[0031] The electric actuator A401 can be controlled by the operation panel outside the bottom shell 1. The electric actuator A401 adopts an electro-hydraulic actuator, which can store force 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 inside the discharge pipe 310 and is attached to its inner wall. A connecting piece 4043 is fixedly installed at the bottom of the discharge pipe 4041. The lower end of the connecting piece 4043 is fixed to the gasket 403. The upper end of the discharge pipe 4041 is located inside the material barrel 304. The paddle 4042 is located inside the material barrel 304 and is fixed to one side of the upper end of the discharge pipe 4041. When the discharge pipe 4041 moves to the lowest point, the paddle 4042 contacts the inner bottom wall and side of the material barrel 304. The side of the feed tube 4041 is provided with an opening 4044 that extends through both the inside and outside.

[0033] The material of the scraper 4042 is relatively thin, with one side being thin and the other side being convex. It can scrape off the ultraviolet absorber on the side wall of the material barrel 304. The opening structure of the feed pipe 4041 is similar to that of the scraper 4042, with one side being thinner, which is used for scraping material.

[0034] The rotary packaging assembly 2 includes an outer cover 201, a turntable 202, and a motor B203. The outer cover 201 is fixed to the bottom of the sealing light shield 301, and the two have internal cavities connected. The outer cover 201 is fixed to the inside of the bottom shell 1. The turntable 202 is located inside the bottom end of the outer cover 201. The motor B203 is fixed to the inner bottom wall of the bottom shell 1. The output shaft of the motor B203 is fixed to the center of the bottom surface of the turntable 202. An end cap feeder 204 and a capping device 205 are fixedly installed on the outer cover 201. Multiple packaging mechanisms 206 are also installed on the turntable 202. The multiple packaging mechanisms 206 are evenly distributed around the turntable 202. The packaging mechanisms 206 can enter the sealing light shield 301 and correspond to the end cap feeder 204 and the capping device 205 respectively. One end of the outer cover 201 is provided with an outlet, and a light-shielding pad is installed on the outlet. The outlet can be opened by rotating any of the sealing mechanisms 206 to the outlet.

[0035] The outer circle of the turntable 202 is basically in contact with the inner wall of the outer cover 201, with a small gap between them. This does not affect the rotation of the turntable 202 and can effectively block light. The end cap feeder 204 is a tubular structure that can store stacks of end caps inside. Driven by the electromagnetic controller, the end caps can gradually fall onto the material hopper. The capping device 205 is a traditional rotating capping device. After the end caps fall onto the material hopper, the capping device 205 rotates to fix the two together. The capping device 205 can also be selected from various capping devices such as hydraulic capping devices to adapt to different types of material hoppers.

[0036] The outlet is a circular structure that matches the size of the packaging mechanism 206. There are two light-shielding pads, or one can be used. When the material bin extends from inside the outer cover 201, it can push open the light-shielding pad. When it falls, the light-shielding pad can be closed by gravity. The material bin can be removed when it extends, or a new one can be loaded in.

[0037] The packaging mechanism 206 includes a telescopic tube 2061, a top post 2062, a tray 2063, and a limiting lever 2064. The top post 2062 is fixed to the upper surface of the turntable 202. The telescopic tube 2061 is sleeved on the top post 2062, with its bottom end fixed to the turntable 202 and its top end fixed to the tray 2063. The tray 2063 has a ring structure, and the top post 2062 can pass through the tray 2063. The limiting lever 2064 has multiple levers distributed in a ring, and each limiting lever 2064 is fixed to the outer ring of the upper surface of the tray 2063. The telescopic tube 2061 can actively extend to drive the tray 2063 to rise to the discharge tube 310, at which time the upper end of the limiting lever 2064 contacts the U-shaped rod 402.

[0038] The telescopic tube 2061 uses a pneumatic telescopic device, but can also be electric, and is a common active telescopic component in existing encapsulation equipment.

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

[0040] The ball-head structure of the U-shaped rod 402 can be impacted without damaging it.

[0041] The bottom end of the sealing ring 311 has a flared opening structure. The gasket 403 matches the shape of the sealing ring 311. The bottom end of the material barrel 304 has a conical recess. The paddle 4042 matches the recess and the internal shape of the material barrel 304.

[0042] The inner ring of the sealing ring 311 has a rubber gasket, and the gasket 403 fits tightly with it. When the two are in close contact, they can achieve a good seal. The sealing mechanism 303 includes an electric push rod B3031 and a sealing plug 3032. The electric push rod B3031 is fixed to the sealing light shield 301, and the sealing plug 3032 is fixed to the output end of the electric push rod B3031. The sealing plug 3032 is used to seal the upper end of the feed pipe 309.

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

[0044] Multiple casters 5 are installed at the bottom of the base shell 1.

[0045] In use, start motor A305, align the feed pipe 309 of the material tank 304 with the elastic injection mechanism 302, and the powdered ultraviolet absorber can be added into the material tank 304 through the feed pipe 309. After filling, rotate the material tank 304 to align the feed pipe 309 with the sealing mechanism 303. The sealing mechanism 303 can seal the material tank 304, at which point the ultraviolet absorber inside the material tank 304 can be sealed and protected from light. When it is necessary to release the ultraviolet absorber, extend the electric actuator A401. The electric actuator A401 can drive the gasket 403 away from 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 which point the material tank 304 can be lowered. The feed tube 4041 rotates, and the feed tube 4041 drives the paddle 4042 to stir the ultraviolet absorber inside the feed hopper 304, so that the powdered ultraviolet absorber can be discharged more smoothly. The existing feed hopper is placed on the tray 2063 and between multiple limiting paddles 2064. When the turntable 202 rotates and drives the feed hopper to rotate, corresponding to the discharge tube 310, the telescopic tube 2061 extends and sends the feed hopper into the sealed light shield 301. At this time, the electric push rod A401 extends, and the gasket 403 will extend into the feed hopper. After the feeding is about to be completed, the micro-movement turntable 202 will cause the limiting paddle 2064 to collide with the U-shaped rod 402. At this time, the powder on the edge of the gasket 403 will fall into the feed hopper. The feed hopper that has been fed can be put on the end cap by the end cap feeder 204 and sealed by the capping device 205.
