[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1 , Figure 2 As shown, this utility model provides a quantitative liquid injection device for producing liquid masks, including an injection platform 1. A liquid supply mechanism 2 is provided on the rear side of the top of the injection platform 1, and an injection mechanism 3 is provided on the front side of the liquid supply mechanism 2. A discharge mechanism 4 is provided on the left side of the rear end of the injection platform 1. A top plate 11 and a semi-circular guard plate 13 are fixedly installed on the top of the injection platform 1. A semi-circular plate 12 is fixedly installed on the front side of the top plate 11, and the semi-circular guard plate 13 is located on the front side of the semi-circular plate 12. The liquid supply mechanism 2 includes a liquid mask storage tank 21. A liquid pump 22 is fixedly installed on the top of the liquid mask storage tank 21, and the input end of the liquid pump 22 penetrates into the interior of the liquid mask storage tank 21. The liquid pump 22 is fixedly connected to the output end of the cavity with a liquid supply hose 24. The liquid injection mechanism 3 includes an electric push rod 31. An L-shaped lifting plate 32 is fixedly installed at the output end of the electric push rod 31. A semi-circular downward moving plate 34 is fixedly installed at the bottom vertical part of the L-shaped lifting plate 32. The electric push rod 31 and the liquid mask storage tank 21 are both fixedly installed on the top of the top plate 11. A discharge guard plate 131 is fixedly installed at the left rear end of the semi-circular guard plate 13. Two limiting slide rods 33 are fixedly installed on the top of the top plate 11. The semi-circular downward moving plate 34 is slidably connected to the two limiting slide rods 33. A capped liquid filling pipe 23 that penetrates the inner cavity is fixedly connected to the rear side of the liquid mask storage tank 21.
[0024] When injecting liquid mask liquid into a container, multiple containers can be placed simultaneously into the gap between the semicircular protective plate 13 and the semicircular plate 12. By activating the electric push rod 31, the semicircular lowering plate 34 can be driven to descend as a whole by the connection between the vertical part of the L-shaped lifting plate 32 and the semicircular lowering plate 34. During descent, the sliding connection between the semicircular lowering plate 34 and the limiting slide rod 33 maintains the stability of the rise and fall. At the same time, the syringe 342 can be controlled to inject the container. The liquid mask source can be obtained by filling the liquid mask storage tank 21 with liquid in advance through the capped liquid filling tube 23. Then, the liquid pump 22 can be activated to extract the liquid from the liquid mask storage tank 21 and output it through the liquid supply hose 24.
[0025] like Figure 3 , Figure 4As shown, the semicircular downward moving plate 34 has several through holes 341 arranged in a ring array. Injectors 342 are inserted through the inner sides of each through hole 341. An electric control valve 343 is fixedly connected to the top of each injector 342, and an infusion tube 344 is fixedly connected to the top of each electric control valve 343. The end of each infusion tube 344 away from the electric control valve 343 is fixedly connected to a supply hose 24. Several sets of left and right adjusting plates 345 are fixedly installed in a ring array on the top of the semicircular downward moving plate 34. The two adjusting plates 345 are located on the left and right sides of each injector 342. Positioning threaded holes are opened on both sides of each injector 342. Several through-holes 3451 are opened on each adjusting plate 345. The inner ring of 3451 is threaded with bolts 3452, and the positioning threaded hole is aligned with one of the several adjustment threaded holes 3451 opened on the corresponding side adjustment plate 345. The front side of the semicircular plate 12 is fixedly installed with several sets of semicircular rubber columns 123 in pairs. The rear side of the semicircular guard plate 13 is provided with several embedding grooves 132. Each of the embedding grooves 132 is provided with threaded holes 133 that extend to the front side of the semicircular guard plate 13. The inner ring of the threaded hole 133 is threaded with a threaded rod 134. The rear end of the threaded rod 134 is fixedly installed with a pressure plate 1341. The several threaded rods 134 are located on the front side of several sets of two semicircular rubber columns 123, and the pressure plate 1341 is embedded in the embedding groove 132. The front end of the threaded rod 134 is fixedly installed with a knob 1342.
[0026] Liquid mask solution can be injected into syringe 342 through several infusion tubes 344. The injection volume can be controlled by the synchronous start and stop of the electronic control valve 343. When the position of the fixed bottle opening changes due to different container sizes, the syringe 342 can be adjusted forward and backward by aligning the positioning threaded holes on both sides of the syringe 342 with the adjustment threaded holes 3451 on the adjusting plates 345 on both sides. The position of the syringe 342 is then adjusted and fixed by tightening bolts 3452 through the adjustment threaded holes 3451 and the positioning threaded holes, thus adapting it to different container openings for injection. When installing the container, the container can be placed between the semi-circular protective plate 13 and the semi-circular plate 12, and pressed against the two sets of semi-circular rubber pillars 123. Then, rotating the knob 1342 will drive the threaded rod 134 to rotate. The threaded connection between the threaded rod 134 and the threaded hole 133 can control the pressure plate 1341 embedded in the groove 132 to move out. The rubber pads on one side of the pressure plate 1341 are used to squeeze the container, so that the container is fixed between the pressure plate 1341 and the two adjacent semi-circular rubber pillars 123. This can accommodate liquid mask production containers of different sizes.
[0027] like Figure 5As shown, a rotating plate 121 is provided at the top center of the semicircular plate 12. The rotating plate 121 is driven by a motor. The motor can be controlled by an encoder of existing technology to rotate 180 degrees and then reverse and reset. A push plate 122 is fixedly installed on the bottom of the rotating plate 121 near the semicircular guard plate 13. The push plate 122 is located between the semicircular guard plate 13 and the semicircular plate 12. An inclined discharge trough 14 is provided on the top left side of the liquid injection platform 1. The gap between the semicircular guard plate 13 and the semicircular plate 12 is connected to the inclined discharge trough 14. An installation groove 141 is provided at the bottom of the inner wall of the inclined discharge trough 14. Several pulleys 142 are evenly installed between the left and right sides of the inner wall of the installation groove 141. The discharge mechanism 4 includes two discharge side plates 41. The gap between the two discharge side plates 41 is connected to the inner cavity of the inclined discharge trough 14. Pulleys 42 are evenly installed between the opposite surfaces of the two discharge side plates 41.
[0028] After the container filling is completed, the pressure plate 1341 can be reversed and retracted into the embedded groove 132. Then, the motor-driven rotating plate 121 can be started and slowly rotated 180 degrees before returning to its original position. The push plate 122 can then be used to push several partially filled containers toward the inclined discharge chute 14 until they reach the pulley 142 on the inner side of the mounting groove 141. The containers can then slowly slide onto the pulley 42 between the two discharge side plates 41. The container caps can then be installed by using an external conveyor belt. When the push plate 122 slowly rotates and pushes the containers, the centrifugal force will cause the containers to move away from the semi-circular rubber column 123 and closer to the semi-circular guard plate 13, effectively preventing them from tripping.
[0029] The working principle of the liquid mask production quantitative injection device will be explained in detail below.
[0030] like Figure 1-5As shown, when injecting liquid mask liquid into a container, multiple containers can be placed simultaneously into the gap between the semicircular protective plate 13 and the semicircular plate 12. By activating the electric push rod 31, the semicircular lowering plate 34 can be driven to descend as a whole by the connection between the vertical part of the L-shaped lifting plate 32 and the semicircular lowering plate 34. During descent, the sliding connection between the semicircular lowering plate 34 and the limiting slide rod 33 maintains the stability of the rise and fall. At the same time, the syringe 342 can be controlled to inject the liquid into the container. The source of the liquid mask can be the liquid filling tube 23 with a cap to fill the inner cavity of the liquid mask storage tank 21 beforehand, and then the liquid pump 22 can be activated to dispense the liquid. Liquid is drawn from the inner cavity of the reservoir 21 and output through the supply hose 24. It is then injected into the syringe 342 through several infusion tubes 344. The injection volume can be controlled by the synchronous start and stop of the electronic control valve 343. When the position of the fixed bottle opening changes due to different container sizes, the syringe 342 can be adjusted forward and backward by aligning the positioning threaded holes on both sides of the syringe 342 with the adjustment threaded holes 3451 on the adjustment plates 345 on both sides. The position of the syringe 342 is then adjusted and fixed by passing the bolts 3452 through the adjustment threaded holes 3451 and tightening them with the positioning threaded holes. This allows it to be used to inject into different container openings. Simultaneously, when installing the container, it can be placed between the semi-circular protective plate 13 and the semi-circular plate 12, and pressed against the two sets of semi-circular rubber pillars 123. Then, rotating the knob 1342 will drive the threaded rod 134 to rotate. The threaded connection between the threaded rod 134 and the threaded hole 133 can control the pressure plate 1341 embedded in the groove 132 to move out. The rubber pads adhered to one side of the pressure plate 1341 will compress the container, fixing it between the pressure plate 1341 and the two adjacent semi-circular rubber pillars 123. This allows it to be adapted to liquid mask production containers of different sizes. After filling, the pressure plate 1341 can be reversed. The container retracts into the embedded groove 132, and then the motor-driven rotating plate 121 slowly rotates 180 degrees before returning to its original position. The push plate 122 can then be used to push several partially filled containers toward the inclined discharge chute 14 until they reach the pulley 142 inside the mounting groove 141. The containers can then slowly slide onto the pulley 42 between the two discharge side plates 41, and the container caps can be installed later with the help of the external conveyor belt. When the push plate 122 slowly rotates and pushes the containers, the centrifugal force will cause the containers to move away from the semi-circular rubber column 123 and closer to the semi-circular guard plate 13, effectively preventing them from tripping.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
