[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 2 - Figure 4This utility model provides an embodiment of a rotary control device for a dispensing syringe, including a bracket 1. The upper outer wall of the bracket 1 is connected to an adjusting mechanism for moving the bracket 1 (existing technology). A motor 14 is fixedly connected to the rear outer wall of the bracket 1. The operation of the motor 14 drives the second gear 13 to rotate. A connecting column 7 is rotatably connected to the front inner wall of the bracket 1. The connecting column 7 is used to connect the first gear 12 and the first clamping block 3. The rotation of the first gear 12 drives the first clamping block 3 to rotate through the connecting column 7, adjusting the position of the first clamping block 3. The first gear 12 is fixedly connected to the outer wall of the connecting column 7. The first gear 12 drives the first clamping block 3 to rotate through the gear... The rotation of wheel 13 drives the connecting column 7 to rotate. Gear 13 meshes with the upper side of gear 12. Gear 12 is driven to rotate by the operation of motor 14. The inner wall of gear 13 is fixedly connected to the output shaft of motor 14. Clamping block 3 is fixedly connected to the outer wall of the front end of connecting column 7. Clamping block 3 cooperates with clamping block 2 to clamp the rubber cylinder 2. Clamping block 2 is rotatably connected to the inner wall of the left side of the front end of clamping block 3. The setting of clamping block 2 cooperates with clamping block 3 to fix the rubber cylinder 2. A slip ring 10 is elastically connected to the inner wall of the upper right side of clamping block 3 through spring 9. The slip ring 10 is connected to the limiting column 8. As the slip ring 10 moves, the ball bearing 11 rolls. The outer wall of the slip ring 10 is slidably connected to the inner wall of the clamping block 3. One end of the spring 9 is fixedly connected to the upper right inner wall of the clamping block 3, and the other end of the spring 9 is fixedly connected to the upper outer wall of the slip ring 10. A limit post 8 is fixedly connected to the inner outer wall of the slip ring 10. The inclined surface of the front end of the limit post 8 is pressed upward by the outer wall of the clamping block 5. The upward movement of the limit post 8 causes the slip ring 10 to move upward synchronously, pressing the spring 9. After the clamping block 5 moves into place, the limit post 8 pops out downward by the elastic force of the spring 9 and locks into the upper part of the clamping block 5. The inner wall of the clamping block 2 5 is used to fix the clamping block 8. The bottom outer wall of the limiting post 8 is inclined. The side wall of the limiting post 8 is slidably connected to the upper right inner wall of the clamping block 1 3. The lower outer wall of the limiting post 8 is engaged with the upper right inner wall of the clamping block 2 5. A ball bearing 11 is rotatably connected to the right inner wall of the slip ring 10. The ball bearing 11 rolls as the slip ring 10 moves, providing guidance for the movement of the slip ring 10. There are two balls bearing 11, which are symmetrically arranged. The inner side of the clamping block 1 3 contacts the dispensing component, which is used for dispensing adhesive. A lubrication component is provided on the inner wall of the bracket 1, which is used for injecting lubricating liquid.
[0037] Reference Figure 4 and Figure 5The lubrication assembly includes a liquid reservoir 16 for temporarily storing lubricating fluid. The liquid reservoir 16 is fixedly connected to the inner wall of the bracket 1. A fixing plate 19 is fixedly connected to the inner wall of the liquid reservoir 16. The fixing plate 19 provides support for the installation of the second spring 17 and the sliding of the guide rod 18. A sealing block 15 is elastically connected to the bottom outer wall of the fixing plate 19 through the second spring 17. The sealing block 15 is squeezed by the outer wall of the second gear 13, and the sealing block 15 will move upward, creating a small gap between the sealing block 15 and the liquid reservoir 16. The lubricating fluid in the liquid reservoir 16 will then flow along the sealing block. The fluid flows from the outer wall of the sealing block 15 onto the gear 13, providing lubrication. The sealing block 15 is spherically shaped, with its lower outer wall engaged with the bottom inner wall of the liquid tank 16. One end of the spring 17 is fixedly connected to the bottom outer wall of the fixing plate 19, and the other end is fixedly connected to the upper outer wall of the sealing block 15. A guide rod 18 is fixedly connected to the upper outer wall of the sealing block 15, guiding the movement of the sealing block 15. The upper outer wall of the guide rod 18 is slidably connected to the bottom inner wall of the fixing plate 19.
[0038] Reference Figure 1 The dispensing assembly includes a glue tube 2, which contains glue. The side wall of the glue tube 2 contacts the inner wall of the front end of the clamping block 3. An air pipe 6 is detachably installed on the inner wall of the upper end of the glue tube 2. The air pipe 6 supplies air into the glue tube 2, so that the glue in the glue tube 2 is discharged through the dispensing head 4. The dispensing head 4 is fixedly connected to the outer wall of the bottom end of the glue tube 2.
[0039] Working principle: The glue cartridge 2 is placed into clamping block 3. Then, clamping block 5 is rotated. The inclined surface of the front end of the limiting post 8 is squeezed by the outer wall of clamping block 5 and moves upward. The upward movement of the limiting post 8 drives the slip ring 10 to move upward simultaneously, squeezing spring 9. After clamping block 5 is in place, the limiting post 8 pops out downward by the elastic force of spring 9 and locks onto the upper inner wall of clamping block 5 to fix clamping block 5, thus clamping the glue cartridge 2. According to the dispensing position, motor 14 is started. The operation of motor 14 drives gear 13 to rotate. The rotation of wheel 13 drives gear 12 to rotate. The rotation of gear 12 drives clamping block 3 to rotate through connecting column 7, adjusting the position of dispensing head 4. When motor 14 drives gear 13 to run, the outer wall of gear 13 presses against the bottom outer wall of sealing block 15. Sealing block 15 is pressed by the outer wall of gear 13 and moves upward, creating a small gap between sealing block 15 and liquid tank 16. The lubricant in liquid tank 16 then flows along the outer wall of sealing block 15 onto gear 13, lubricating gear 13.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
