Description

Technical Field

A common solution is to place the resin particles scooped out by the small spoon on a weighing paper and then pour it into the hole. This process is difficult, makes it hard to control the amount of resin particles added, and reduces the efficiency of resin particle addition. Utility Model Content

A feed inlet 11 is provided through one end of the upper part of the dosing tube 1, and a rotating shaft 10 is rotatably connected to the other end of the dosing tube 1. A threaded ring 14 is fixedly connected to the outer end of the rotating shaft 10. A screw 9 is threadedly connected inside the threaded ring 14, and a push plate 17 is fixedly connected to the screw 9 through the dosing tube 1. The resin particles can be fed into the interior of the dosing tube 1 through the feed inlet 11, and the threaded ring 14 can be stably rotated under the action of the rotating shaft 10.

[0024] A slide rod 18 is fixedly connected to one end of the outer side of the push plate 17. The slide rod 18 is slidably connected inside the dosing tube 1. By setting the slide rod 18, the push plate 17 can be restricted to prevent the push plate 17 from rotating with the screw 9. The motor 13 is started. Under the action of the motor 13 and the reducer 16, the gear 6 is driven to rotate. Under the meshing action, the gear 15 at the other end can be driven to rotate. The gear 15 can drive the threaded ring 14 to rotate. Under the restriction of the threaded connection and the slide rod 18, the screw 9 drives the push plate 17 to move inward, thereby pushing the resin particles outward from the dosing head 2 to realize the resin particle dosing operation.

[0025] The other end of the screw 9 is fixedly connected to the limiting plate 8, and the outer end of the threaded ring 14 is fixedly connected to the gear 6. By setting the limiting plate 8, the limiting ability of the screw 9 can be realized, and the stability of the entire push plate assembly during use can be improved.

The whole device has a high degree of automation and can control the quantitative dosing, saving time and effort.

[0028] Working principle: During use, resin granules are fed into the dosing pipe 1 through the feed pipe 11. Then, the operator holds the handle 5 and aligns the dosing head 2 with the dosing equipment. The motor 13 is started, and under the action of the motor 13 and the reducer 16, the gear 6 rotates. Under the meshing action, the gear 15 at the other end rotates. The gear 15 drives the threaded ring 14 to rotate. Under the constraint of the threaded connection and the slide rod 18, the screw 9 drives the push plate 17 to move inward, thereby pushing the resin granules outward from the dosing head 2, realizing the resin granule dosing operation. Through the electrical connection between the control panel 3 and the reducer 16 and the motor 13, timed control is realized. The control panel 3 can realize accurate timed control, so that the reducer motor rotates only once within a specified time. The program can be set so that the controller controls the motor to rotate within a specified time and automatically stops after reaching the specified position, thus achieving quantitative dosing of resin granules.
