Description

Technical Field

[0001] The present invention relates to the technical field of injection valves, and particularly to a method for nozzle-free debugging. Background Art

[0002] For current injection valves, after any one of the parts such as the nozzle, nozzle cap, plunger, and fluid tank is cleaned, the height of the nozzle needs to be recalibrated during assembly. This height determines the glue dispensing state and requires multiple debuggings to reach the best condition. Therefore, the debugging takes a long time, usually about one hour or even longer. Even when debugged by experienced personnel, it cannot be guaranteed that the height is the same each time, and repeated debugging is required, which is very troublesome. Summary of the Invention

[0003] In view of the above problems, the present invention provides a method for nozzle-free debugging, effectively solving the deficiencies in the prior art.

The retaining ring is rotatably connected to the upper part of the connecting stud in a movable manner. The nozzle is installed in the nozzle cap, and the nozzle cap is rotatably connected to the lower part of the connecting stud in a movable manner. The nozzle cap and the retaining ring are arranged corresponding to each other. One end of the plunger is arranged in the connecting stud and corresponds to the nozzle.

[0006] According to the above solution, a positioning device is correspondingly arranged on the retaining ring.

[0007] According to the above solution, the positioning device includes a retaining ring clip and a screw. The retaining ring clip corresponds to the retaining ring and is locked by the screw.

[0011] According to the above solution, the connecting stud is provided with an external thread for facilitating the rotational connection of the retaining ring and the nozzle cap and a through hole for facilitating the plunger to pass through the connecting stud.

[0012] According to the above solution, internal threads corresponding to the external threads are provided on both the retaining ring and the inner wall of the nozzle cap. Knurling for anti-slip is provided on the outer wall of the retaining ring, and a groove for anti-slip is provided on the outer wall of the nozzle cap.

Detailed implementation mode

[0028] The technical solution of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0029] As Figures 1 to 11 shown, a nozzle non-adjustment mechanism of the present invention includes a fluid tank 1, a stop ring 2, a nozzle 3, a nozzle cap 4 and a firing pin 5. A connecting stud 11 is provided on the fluid tank 1. The stop ring 2 is rotatably connected to the upper part of the connecting stud 11 movably. The nozzle 3 is installed in the nozzle cap 4. The nozzle cap 4 is rotatably connected to the lower part of the connecting stud 11 movably. The nozzle cap 4 and the stop ring 2 are arranged correspondingly. One end of the firing pin 5 is arranged in the connecting stud 11 and corresponds to the nozzle 3. The above constitutes the basic structure of the present invention.

[0030] With such a structural arrangement of the present invention, its working principle is as follows: Before debugging, the stop ring 2 is rotatably connected to the upper part of the connecting stud 11 on the fluid tank 1. Then the nozzle 3 is installed in the nozzle cap 4. Then the nozzle cap 4 is rotatably connected to the lower part of the connecting stud 11. Gradually rotate from bottom to top to the required height. The height can be determined according to the force of one end of the firing pin 5 arranged in the connecting stud 11 hitting the nozzle 3 to determine the optimal height of the nozzle cap 4. After the nozzle cap 4 is adjusted to the optimal height, rotate the stop ring 2 gradually from top to bottom until it is tightly attached to the nozzle cap 4, so as to realize the limit of the nozzle cap 4 by the stop ring 2. When disassembling the nozzle 3 and the nozzle cap 4 for cleaning, only need to rotate the nozzle cap 4. At this time, the position of the stop ring 2 remains unchanged. After the nozzle 3 and the nozzle cap 4 are cleaned, reinstall the nozzle 3 in the nozzle cap 4, and then rotatably connect the nozzle cap 4 to the connecting stud 11 until it is tightly attached to the stop ring 2. At this time, the height of the nozzle cap 4 is the optimal height of the previous debugging. Its installation time can be controlled to be completed within a few minutes. The operation is very convenient and achieves the effect of non-adjustment. That is to say, there is no need to re-calibrate the height of the nozzle cap 4. Only need to rotate the nozzle cap 4 until it is tightly attached to the stop ring 2, saving a lot of time.

[0031] In this embodiment, a positioning device is correspondingly arranged on the stop ring 2. With such a structural arrangement, the stop ring 2 is positioned through the positioning device to prevent its displacement, which is convenient for the installation of the nozzle cap 4 next time.

[0032] In this embodiment, the positioning device includes a retaining ring clip 6 and a screw 7. The retaining ring clip 6 is correspondingly arranged with the retaining ring 2 and is locked by the screw 7. With such a structural arrangement, the retaining ring 2 is positioned by the retaining ring clip 6 and locked by the screw 7, achieving the positioning effect of the retaining ring 2.

[0033] In this embodiment, the retaining ring clip 6 is provided with a clamping hole 61 for clamping the retaining ring 2 and a screw hole 62 for locking the screw 7.

[0034] In this embodiment, the retaining ring clip 6 is provided with a first clip end 63 and a second clip end 64. The first clip end 63 and the second clip end 64 are arranged at intervals, and corresponding screw holes 62 are respectively provided on the first clip end 63 and the second clip end 64. With such a structural arrangement, during installation, the first clip end 63 and the second clip end 64 are separated, the clamping hole 61 wraps the retaining ring 2, and then the first clip end 63 and the second clip end 64 are closed, and the screw holes 62 on the first clip end 63 and the second clip end 64 are locked by the screw 7, causing the first clip end 63 and the second clip end 64 to deform, thereby locking the retaining ring 2.

[0035] In practical applications, the clamping groove between the first clip end 63 and the second clip end 64 communicates with the clamping hole 61.

[0036] In this embodiment, it further includes a heating block 8. The heating block 8 is sleeved outside the fluid tank 1, the retaining ring 2, the nozzle cap 4, and the retaining ring clip 6. With such a structural arrangement, the heating block 8 can heat the glue in the fluid tank 1 and the nozzle 3, and can also play a role in locking the nozzle cap 4 to prevent the nozzle cap 4 from loosening and displacing.

[0037] In this embodiment, the connecting stud 11 is provided with an external thread 111 for facilitating the screw connection between the retaining ring 2 and the nozzle cap 4 and a through hole 112 for facilitating the striker 5 to pass through the connecting stud 11.

[0038] In this embodiment, internal threads 21 corresponding to the external thread 111 are respectively provided on the inner walls of the retaining ring 2 and the nozzle cap 4. Knurling 22 for anti-slip is provided on the outer wall of the retaining ring 2, and a groove 42 for anti-slip is provided on the outer wall of the nozzle cap 4.

[0039] In this embodiment, the nozzle cap 4 is provided with a nozzle hole 41 corresponding to the nozzle 3. The nozzle 3 is provided with a step 31 for positioning with the connecting stud 11 and a nozzle bayonet 32 for corresponding impact with the striker 5.

[0040] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the spirit of the present invention and the scope protected by the claims. All of these fall within the protection scope of the present invention.
