The filling head further comprises a cavity tube and a sliding sleeve sleeved outside the cavity tube. The cavity tube has a cavity, and the pressing block is arranged in the cavity and can move telescopically in the cavity. The side of the cavity tube is provided with a feeding port, and the bottom of the cavity tube is provided with a discharging port. The sliding sleeve and the cavity tube can slide relative to each other, and the lower part of the sliding sleeve exceeds the lower edge of the feeding port.

Meanwhile, the size of the cavity in the filling head can be adjusted, and the filling head is convenient to use.

[0004] In view of the related technologies in the above, the inventors find that the following defects exist: In the process of discharging, the sliding sleeve on the UV glue filling head cannot cover the cavity tube, so that the UV glue in the cavity tube is prone to solidification.

[0005] Therefore, in view of the above problems, the applicant provides a UV glue filling head. CONTENT OF THE UTILITY MODEL

[0006] In order to solve the problems mentioned in the background, the application provides a UV glue filling head.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] This application discloses a UV glue filling head.

[0026] like Figures 1-4 As shown, a UV glue filling head includes a filling head, a fixing sleeve 8 and a cavity tube 4. The fixing sleeve 8 is provided with an interception mechanism, which includes an interception net 9, a fan-shaped plate 10 and a nut 11. The interception net 9 is inserted into the fixing sleeve 8, and the top of the interception net 9 is fixedly connected to the fan-shaped plate 10. The fan-shaped plate 10 is threadedly connected to the nut 11.

[0027] The cavity tube 4 is equipped with an ultraviolet protection mechanism, which includes a sunshade sleeve 5. An "I"-shaped groove 40 is opened on the outer circumference of the cavity tube 4, and a slider 6 is slidably connected to the "I"-shaped groove 40.

[0028] Please see Figure 1 and Figure 2 The filling head consists of a cylinder 1, a push rod 2, a pressure block 3, a cavity tube 4, and a feed pipe 7. The output end of the cylinder 1 is fixedly connected to the push rod 2, and the bottom end of the pressure block 3 is fixedly connected to the pressure block 3. The pressure block 3 is located in the cavity of the cavity tube 4. The cavity tube 4 is connected to the feed pipe 7. The cylinder 1 is connected to an external power source. The output end of the cylinder 1 is pushed down from the input end and drives the push rod 2, the pressure block 3, and the cavity tube 4 to fall. When the cavity tube 4 falls into the receiving bottle 13, the feed pipe 7 begins to feed material into the cavity tube 4. At the same time, the output end of the cylinder 1 is pushed down from the input end and drives the pressure block 3 to push the material from the outlet of the cavity tube 4 into the receiving bottle 13.

[0029] Please see Figure 4 Multiple sliders 6 are fixedly connected in a ring array on the inner circumference of the sunshade sleeve 5. The multiple sliders 6 are slidably connected to the "I"-shaped groove 40. The outlet of the cavity tube 4 is opened at the middle of the bottom of the cavity tube 4. The bottom of the sunshade sleeve 5 has a diameter larger than that of the outlet of the cavity tube 4. The purpose of opening the bottom of the sunshade sleeve 5 larger than the diameter of the outlet of the cavity tube 4 is mainly to make the outer circumference of the sunshade sleeve 5 contact the inner side wall of the receiving bottle 13, that is, to avoid the outlet of the cavity tube 4 directly contacting the top of the receiving bottle 13 for a long time, which would cause wear or damage during contact.

[0030] Please see Figure 2 The bottom end of the sunshade sleeve 5 contacts the inner wall of the receiving bottle 13. The outer wall of the sunshade sleeve 5 is coated with an ultraviolet protection coating. The ultraviolet protection coating is mainly designed to prevent ultraviolet rays from solidifying the UV adhesive in the cavity tube 4.

[0031] Please see Figure 1 The feed pipe 7 is equipped with a fixing sleeve 8, and the fixing sleeve 8 has a groove 80. The top of the groove 80 has a threaded hole A81. The intercepting net 9 is inserted into the groove 80. The bottom of the fan-shaped plate 10 is equipped with a sealing ring. The shape of the groove 80 matches the intercepting net 9 and the fan-shaped plate 10. The sealing ring is mainly set to prevent UV glue from flowing out from the gap between the fan-shaped plate 10 and the groove 80.

[0032] Please see Figure 3A handle is fixedly connected to the top of the fan-shaped plate 10. A threaded hole 100 passes through the top of the fan-shaped plate 10. A nut 11 is threadedly connected to the threaded hole 100 and extends into the threaded hole A81. A feed pipe 12 is installed on the fixed sleeve 8. The operator holds the handle and inserts the fan-shaped plate 10 and the interceptor net 9 into the slot 80. The nut 11 is then screwed into the threaded hole 100 and the threaded hole A81 to make the interceptor net 9 and the fan-shaped plate 10 fit tightly against the fixed sleeve 8. At the same time, when the UV glue flows from the feed pipe 12 into the fixed sleeve 8, the interceptor net 9 can intercept some larger particles of UV glue that have not been mixed evenly, preventing them from being discharged from the outlet of the cavity tube 4 and causing blockage.

[0033] The implementation principle of a UV glue filling head according to an embodiment of this application is as follows:

[0034] Cylinder 1 is connected to an external power source. The output end of cylinder 1 is pushed down from the input end, which drives push rod 2, pressure block 3 and cavity tube 4 to fall. When cavity tube 4 falls into receiving bottle 13, feed pipe 7 starts to feed into cavity tube 4. At the same time, the output end of cylinder 1 is pushed down from the input end, which drives pressure block 3 to push the material from the outlet of cavity tube 4 into receiving bottle 13. In the UV protection mechanism, slider 6 slides in the "I"-shaped slide groove 40, so that the sunshade 5 covers cavity tube 4, which facilitates the UV glue to enter cavity tube 4 to play the role of UV protection, while avoiding the problem of UV glue solidification.

[0035] The operator holds the handle and inserts the sector plate 10 and the intercepting net 9 into the slot 80, and screws the nut 11 into the threaded hole 100 and the threaded hole A81 to make the intercepting net 9 and the sector plate 10 fit tightly with the fixed sleeve 8. At the same time, when the UV glue flows into the fixed sleeve 8 from the feed pipe 12, the intercepting net 9 can intercept some larger particles of UV glue that are not mixed evenly, preventing them from being discharged from the outlet of the cavity pipe 4 and causing blockage.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
