Description

Technical Field

[0001] The utility model relates to the technical field of light-curing paint production, in particular to a filling device for light-curing paint. Background Art

[0002] UV-curable coatings, also known as photosensitive coatings, are primarily composed of photosensitive resins, photosensitizers, and diluents. Additives such as heat stabilizers are also added, and pigments and fillers are added during the production of color coatings. During the production process, UV-curable materials require mixing the raw materials and then filling them into containers.

[0003] Current filling devices for UV-curing paint rely solely on the paint's inherent fluidity. Due to the paint's high viscosity, this poor fluidity leads to low filling efficiency. Patent publication CN220333132U discloses a UV paint production and filling device. This device utilizes a first threaded rod to drive a stopper plate up and down, which pushes the UV-curing paint out of a discharge pipe, thereby improving the filling efficiency of the UV-curing paint.

[0004] Although this device accelerates the flow of paint by pushing the plug plate down, the amount of material discharged each time is limited, and the paint stops moving during the rising process of the plug plate, making it intermittent discharge, resulting in low filling efficiency. Therefore, there is an urgent need for a filling device for light-curing paint to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0006] Specifically, the technical problem to be solved by the present invention is to provide a filling device for photocuring paint, so as to solve the technical problem that although the paint flow is accelerated by the descending plug plate, the discharge amount each time is limited, and the paint stops moving during the ascending process of the plug plate, making it intermittent discharge, resulting in low filling efficiency.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A filling device for light-curing paint, comprising a storage box, a discharge port provided at the bottom of the storage box, a sealing ring fixedly connected to the discharge port, a sealing plate abutting against the sealing ring, and a lifting and discharging mechanism installed on the storage box;

[0009] The lifting and discharging mechanism includes a lifting rod vertically arranged in the storage box, the lower end of the lifting rod is connected and fixed to the sealing plate, the upper end passes through the storage box and is connected to the driving plate, and a guide wheel that can be rolled is provided on one side of the driving plate. A rotating shaft is provided on the lifting rod, and a screw dragon is fixedly connected to the lower end of the rotating shaft. The screw dragon is arranged in the discharge port, and the guide wheel and the rotating shaft are driven by a motor.

[0010] As an improved technical solution, the motor is fixedly installed on the top of the storage box, the output end of the motor is fixedly connected to a worm, one side of the worm is meshingly connected to a worm wheel, both sides of the worm wheel are coaxially connected to a crank, a T-shaped rod is slidably connected to the crank, and the T-shaped rod is rotatably connected to the guide wheel.

[0011] As an improved technical solution, one end of the worm is connected to the rotating shaft through a chain, the rotating shaft is rotatably connected to the storage box, and a plurality of stirring rods are fixedly connected to the rotating shaft.

[0012] As an improved technical solution, the top of the storage box is fixedly connected to a support platform, the worm gear is rotatably connected to the support platform, the T-shaped rod is slidably connected to the support platform, and the upper end of the lifting rod is elastically connected to the support platform through a spring.

[0013] As an improved technical solution, the driving plate is in a U-shaped structure, and a slope is provided on the side of the driving plate facing the guide wheel.

[0014] As an improved technical solution, a screw is fixedly connected to the lifting rod, a through hole is opened on the driving plate, the screw passes through the through hole and is threadedly connected to a nut, and the nut is in abutment with the driving plate.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] 1. The utility model drives the auger to rotate by the motor and drives the guide wheel to intermittently contact the driving plate, so that the lifting rod is driven to move up and down intermittently. When the lifting rod rises, it drives the sealing plug to leave the sealing ring, so that the paint can flow downward. At the same time, when the auger rotates, the flow speed of the paint can be increased, so that the paint can flow out of the discharge port quickly, thereby improving the filling efficiency.

[0017] 2. The utility model can change the contact time between the guide wheel and the driving plate by adjusting the position of the driving plate on the lifting rod, thereby changing the separation time between the sealing plug and the sealing ring, and then adjusting the discharge amount each time to improve applicability.

[0029] like Figure 1-4 As shown together, this embodiment provides a filling device for photocuring paint, which includes a storage box 1, a discharge port at the bottom of the storage box 1, a sealing ring 2 fixedly connected to the discharge port, a sealing plate 3 abutting the sealing ring 2, and a lifting and discharging mechanism 4 installed on the storage box 1.

[0030] The lifting and discharging mechanism 4 includes a lifting rod 401 vertically arranged in the storage box 1. The lower end of the lifting rod 401 is connected and fixed to the sealing plate 3, and the upper end passes through the storage box 1 and is connected to the driving plate 402. A guide wheel 403 with rolling contact is provided on one side of the driving plate 402. A rotating shaft 404 is provided on the lifting rod 401. The lower end of the rotating shaft 404 is fixedly connected to a screw dragon 405. The screw dragon 405 is arranged in the discharge port. The guide wheel 403 and the rotating shaft 404 are both driven by a motor 406.

[0031] In the above technical solution, when the motor 406 rotates, it drives the rotating shaft 404 to rotate and can drive the guide wheel 403 to perform horizontal reciprocating motion. When the guide wheel 403 contacts the driving plate 402, it can drive the driving plate 402 and the lifting rod 401 to rise, so that the sealing plug 3 leaves the sealing ring 2, and the paint can flow downward through the discharge port. At the same time, the auger 405 rotates to apply a downward driving force to the paint, so that the paint can accelerate the downward flow, which is beneficial to improving the filling efficiency.

[0032] The motor 406 is fixedly installed on the top of the storage box 1, and the output end of the motor 406 is fixedly connected to the worm 407, and one side of the worm 407 is meshed with a worm wheel 408. Both sides of the worm wheel 408 are coaxially connected to a crank 409, and a T-shaped rod 410 is slidably connected to the crank 409, and the T-shaped rod 410 is rotationally connected to the guide wheel 403.

[0033] In the above technical solution, when the motor 406 drives the worm 407 to rotate, the worm 406 drives the worm wheel 408 to rotate, and the crank 409 drives the T-shaped rod 410 to move back and forth left and right, thereby driving the guide wheel 403 to move synchronously. When the guide wheel 403 moves to the right, it can contact the drive plate 402, so that the drive plate 402 drives the lifting rod 401 to rise.

[0034] One end of the worm 407 is connected to the rotating shaft 404 through a chain. The rotating shaft 404 is rotatably connected to the storage box 1, and a plurality of stirring rods 411 are fixedly connected to the rotating shaft 404.

[0035] In the above technical solution, the rotating shaft 404 drives the auger 405 to rotate and exerts a downward driving force on the paint, while mixing and stirring the paint in the storage box 1 through the stirring rod 411, thereby improving the mixing degree of the paint and the fluidity of the paint.

[0036] The top of the storage box 1 is fixedly connected to a support platform 101 , the worm gear 408 is rotatably connected to the support platform 101 , the T-shaped rod 410 is slidably connected to the support platform 101 , and the upper end of the lifting rod 401 is elastically connected to the support platform 101 through a spring 412 .

[0037] In the above technical solution, the T-shaped rod 410 cooperates with the support platform 101 to slide back and forth horizontally, and the lifting rod 401 is a T-shaped structure. When the lifting rod 401 rises, it drives the spring 412 to stretch and store force. When the guide wheel 403 loses contact with the drive plate 402, the spring 412 drives the lifting rod 401 to descend, so that the sealing plug 3 abuts against the sealing ring 2 to prevent paint overflow.

[0038] The driving plate 402 has a U-shaped structure, and a slope is formed on one side of the driving plate 402 facing the guide wheel 403 .

[0039] In the above technical solution, when the guide wheel 403 contacts the inclined surface, it drives the driving plate 402 to rise, and the driving plate 402 drives the lifting rod 401 to rise, thereby driving the sealing plug 3 to leave the sealing ring 2.

[0040] A screw rod 413 is fixedly connected to the lifting rod 401 . A through hole is opened on the driving plate 402 . The screw rod 413 passes through the through hole and is threadedly connected to a nut 414 . The nut 414 is in abutment with the driving plate 402 .

[0041] In the above technical solution, the driving plate 402 can be moved left and right on the lifting rod 401 for adjustment. The driving plate 402 is connected and fixed to the lifting rod 401 by rotating the nut 414. When the position of the driving plate 402 changes, the contact time of the guide wheel 403 with the driving plate 402 when it moves to the right can be changed, thereby changing the separation time of the sealing plug 3 and the sealing ring 2, and then changing the discharge amount each time.

[0042] When in use, the paint is placed in the processing box 1. When the motor 406 drives the rotating shaft 404 to rotate, the stirring rod 411 stirs and mixes the paint in the storage box 1, the worm 406 drives the worm wheel 408 to rotate, and the crank 409 drives the T-shaped rod 410 to move back and forth left and right, so that the guide wheel 403 moves synchronously. When the guide wheel 403 moves to the right, it can contact the driving plate 402, so that the driving plate 402 drives the lifting rod 401 to rise. At this time, the sealing plug 3 leaves the sealing ring 2. At the same time, under the rotation of the auger 405, the paint can be accelerated to flow out of the discharge port into the container to complete the filling.

[0043] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
