[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the following will further introduce this solution in detail in conjunction with specific embodiments.

[0026] As Figures 1 to 5 shown, an embodiment of the present invention provides a glue spraying nozzle auxiliary liquid discharging device, which includes a liquid discharging pipe 4, a thimble 1, a socket 2, and a pressing sleeve 3. An installation component is provided at the first end of the liquid discharging pipe 4, and the liquid discharging pipe 4 is connected to a glue spraying rod 11 through the installation component. The glue spraying nozzle of the glue spraying rod 11 is located inside the liquid discharging pipe 4; the pressing sleeve 3 is arranged at the second end of the liquid discharging pipe, and the outer wall of the right section of the pressing sleeve 3 is slidably matched with the inner wall of the liquid discharging pipe 4; a limiting step surface for abutting against the end surface of the second end is provided at the connection between the right section of the pressing sleeve 3 and the left section 28 of the pressing sleeve; the socket 2 is arranged in the left section of the pressing sleeve, the thimble is arranged at the middle position of the socket, and the right end of the thimble 1 extends into the liquid discharging pipe and faces the glue spraying nozzle; a locking component for locking or unlocking the pressing sleeve is arranged on the liquid discharging pipe 4; a liquid discharging port 17 is arranged on the lower side of the liquid discharging pipe 4.

[0027] When the glue spraying nozzle auxiliary liquid discharging device provided by the embodiment of the present invention is in use, only need to fix the glue spraying rod 11 in the liquid discharging pipe 4 through the installation component, and then press the pressing sleeve 3 to make the pressing sleeve 3 move towards the direction close to the installation component, then the thimble can be driven to move accordingly through the socket until the ceramic bead at the glue spraying nozzle is pushed open by the thimble 1. At this time, the locking component locks the pressing sleeve 3, and the glue liquid flows out from the glue spraying nozzle and is discharged to other containers through the liquid discharging port in a concentrated manner. It can be seen that the glue spraying nozzle auxiliary liquid discharging device of the present invention can collect the glue liquid sprayed by the glue spraying nozzle through the liquid discharging pipe 4, avoiding the glue liquid from being sprayed onto other equipment or the ground, effectively avoiding the waste of glue liquid; at the same time, because there is a locking component to lock the pressing sleeve, there is no need for someone to keep pressing the pressing sleeve all the time, and the glue spraying state of the glue spraying nozzle can still be maintained, thus having the effect of saving time and effort and greatly improving the cleaning efficiency of the glue supply device.

[0028] Further, the locking assembly includes a pull rod 5, a spring 15, and a connecting plate 22. A plurality of limiting grooves 23 are uniformly distributed on the upper inner wall of the right section of the pressing sleeve. One end of the connecting plate is vertically provided with a clamping plate 13 for cooperating with the limiting grooves 23. The lower end of the pull rod is rotatably connected to the other end of the connecting plate, and the upper end of the pull rod extends vertically outside the liquid discharge pipe. One end of the spring 15 is connected to the connecting plate, and the other end of the spring is connected to the inner wall of the liquid discharge pipe. An installation post 24 is provided on the inner wall of the liquid discharge pipe, and the lower end of the installation post 24 is rotatably connected to the connecting plate. The spring 15 is located between the installation post and the pull rod and is close to the pull rod. With this solution, when the pressing sleeve is pressed, the cooperation between the clamping plate 13 and the limiting grooves 23 is used to lock the pressing sleeve to prevent the pressing sleeve from retracting, thereby preventing the ejector pin from retracting. After the liquid discharge needs to be stopped or the glue is completely discharged, the pull rod 5 is lifted upward, and the clamping plate can be driven by the connecting plate 22 to disengage from the limiting grooves, thereby releasing the locking of the pressing sleeve. At this time, the pressing sleeve can be retracted, and the ejector pin will also retract and move away from the glue spraying nozzle accordingly. It can be understood that the function of the spring 15 is to maintain the cooperation between the clamping plate and the limiting grooves during locking; after unlocking, a restoring force is provided to the connecting plate to facilitate the return of the connecting plate.

[0029] As Figure 4 shown, the end of the clamping plate 13 far from the connecting plate is a right triangle structure, and the inclined surface of the right triangle structure faces away from the pull rod; the limiting groove 23 is a right triangle groove that cooperates with the right triangle structure, so that when the pressing sleeve is pressed, it is convenient for the clamping plate to cooperate with the limiting groove to achieve self-locking and prevent the pressing sleeve from retracting.

[0030] Further, a guiding block 20 is provided on the lower outer wall of the right section of the pressing sleeve 3, and a guiding groove 21 that slidably cooperates with the guiding block is provided on the inner wall of the second end; the extending direction of the guiding groove 21 is parallel to the axis of the liquid discharge pipe, so that the cooperation between the guiding block and the guiding groove 21 can guide the movement of the pressing sleeve and prevent the pressing sleeve from rotating at the same time.

[0031] In order to better prevent the glue from flowing out of the gap between the glue spraying rod and the liquid discharge pipe, a sealing member is provided between the glue spraying rod and the liquid discharge pipe.

[0032] Preferably, the sealing member is an O-ring 14.

[0033] Specifically, the socket 2 is in threaded cooperation with the left section of the pressing sleeve 3, so that by rotating the socket, the length of the ejector pin inserted into the glue spraying nozzle can be finely adjusted, that is, the distance between the ceramic bead and the nozzle of the glue spraying nozzle, thereby controlling the liquid discharge speed.

[0034] Furthermore, the installation assembly includes a fixing plate 9, a mounting block 8, a locking slider 7, and a nut 6. An installation groove 10 for cooperating with the mounting block is provided on the outer wall surface of the glue spraying rod 11; one end of the fixing plate 9 is connected to the inner wall of the first end, and a through hole for accommodating the mounting block is provided on the fixing plate, and the through hole is opposite to the installation groove 10; one end of the locking slider 7 is slidably connected to the sliding groove of the first end, and the extending direction of the sliding groove 25 is parallel to the axis of the drain pipe; an external thread for cooperating with the nut 6 is provided on the outer wall surface of the first end, and a limiting surface for abutting against the nut is provided on the locking slider 7; a pressing inclined surface 27 is provided at one end of the locking slider away from the drain pipe, and a cooperating inclined surface for cooperating with the pressing inclined surface is provided on the mounting block 8. With this solution, only need to put the mounting block 8 into the through hole and the installation groove, and then rotate the nut 6. The nut 6 is used to push the locking slider to slide on the fixing plate until the pressing inclined surface of the locking slider cooperates with the cooperating inclined surface and presses the mounting block in the installation groove, thus realizing the connection between the drain pipe and the glue spraying rod. It can be understood that, as Figure 3 shown, the pressing inclined surface 27 of the locking slider can be seen; a part of the mounting block 8 is located in the installation groove, and the other part is located in the through hole; the locking slider can prevent the mounting block from coming out of the through hole, and the cooperation of the locking slider and the mounting block is used to lock the fixing plate and the glue spraying rod, so that the fixing plate and the glue spraying rod cannot move.

[0035] In order to make the connection between the drain pipe 4 and the glue spraying rod 11 more firm and reliable, the number of the installation assemblies is three, and each installation assembly is evenly distributed in the circumferential direction of the first end; the number of the installation grooves is three, and each installation groove is evenly distributed in the circumferential direction of the glue spraying rod. It can be understood that each installation assembly corresponds to each installation groove one by one.

[0036] Specifically, the glue spraying nozzle auxiliary drainage device provided by the embodiment of the present invention further includes a collection device. The collection device includes a collection bucket 16, and the collection bucket 16 is connected to the drainage port 17 through a rubber tube 18, so that the glue can be conveniently collected and environmental pollution can be avoided.

[0037] The general usage process of the glue spraying nozzle auxiliary liquid discharging device provided by the embodiment of the present invention is as follows: When in use, first sleeved the liquid discharging pipe 4 on the glue spraying rod 7, rotate the liquid discharging pipe 4 to align the through hole of the fixing plate 9 with the installation groove 10, insert the installation block 8 into the through hole and the installation groove, push the locking slider so that the pressing inclined surface fits with the mating inclined surface of the installation block, screw the nut 6 to the position where the locking slider 7 is located to lock the installation block; push the pressing sleeve 3 to move the pressing sleeve towards the direction close to the glue spraying nozzle, and the ejector pin moves accordingly until the ejector pin 1 abuts against the ceramic bead 19 in the nozzle of the glue spraying nozzle. Continue to push the pressing sleeve 3 to push open the ceramic bead, that is, the ceramic bead moves away from the nozzle. At this time, the glue liquid sprays out from the glue spraying nozzle 12; after releasing the hand, the clamping plate 13 is subjected to the elastic force of the spring 15 and is located in the limiting groove of the pressing sleeve 3, so that the pressing sleeve 3 cannot retreat backward, realizing the locking of the pressing sleeve, and the glue liquid will continuously spray out from the glue spraying nozzle 12. The sprayed glue liquid flows into the glue pipe 18 along the liquid discharging port 17 and is centrally recovered into the collecting bucket 16; after the glue supply device is cleaned, vertically pull up the pull rod 5 to make the clamping plate 13 disengage from the limiting groove of the pressing sleeve 3. The ceramic bead 19 will push against the ejector pin 1 to make the ejector pin return to its position until the ceramic bead seals the nozzle of the glue spraying nozzle. At this time, the glue liquid stops spraying, and then the liquid discharging pipe can be separated from the glue spraying rod.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. Moreover, after reading the content of the present invention, those skilled in the relevant art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
