Description
Technical Field
The utility model belongs to the technical field of dispenser equipment, and particularly relates to a striker structure of a dispenser.
Background
In the existing glue dispenser equipment, a jet valve is often adopted, glue fluid at a nozzle is ejected in a glue drop shape after being impacted by a firing pin at a high speed, and thus the glue dispensing working process is completed. The factors of the firing pin and the feeding system of the glue fluid play a main role in the quality of glue dispensing, as shown in fig. 1, the existing injection valve device comprises the firing pin 1, an impact part 2 (in a round head design) of the firing pin, an injection valve body 3, a nozzle 4, a glue feeding mechanism 5 and a glue feeding channel 6, wherein the round head is positioned at the tail part of the firing pin, the firing pin is in an integrated design and moves up and down in the injection valve body to impact the glue fluid, the nozzle 4 is installed at the lower end of the injection valve body, the glue feeding mechanism is fixedly connected with the injection valve body, the glue feeding channel is positioned in the glue feeding mechanism, and the glue feeding channel is communicated with the nozzle. The existing firing pin is when striking the higher gluey fluid of consistency (for example tin cream silver thick liquid), and the striking portion of firing pin is the button head design, and the striking effect is relatively poor, can not spray out tin cream steadily, high accuracy for it is relatively poor to spray out gluey effect.
SUMMERY OF THE UTILITY MODEL
The embodiment of the utility model aims to provide a striker structure of a dispenser, which can improve the dispensing quality and stability of the dispenser.
The embodiment of the utility model is realized as follows:
a striker structure of a dispenser, comprising: the injection valve comprises a striker, an impact part of the striker, an injection valve body and a nozzle, wherein the nozzle is installed at the lower end of the injection valve body, the impact part of the striker is in a flat head shape, and the striker is installed in the injection valve body to move up and down so that the impact part of the striker impacts glue fluid to be sprayed out of the nozzle.
According to the embodiment of the utility model, the impact part of the firing pin is designed to be the flat head part, so that when the firing pin impacts the glue fluid, the stable and high-precision spraying of the glue fluid can be ensured when the viscosity of the glue fluid is high, and by utilizing the cavity pressure principle, because the contact surface of the firing pin of the round head round ball round surface is overlarge, the viscous glue fluid contains powder particles which can jack up the peripheral part of the contact part of the firing pin and the nozzle to form a gap, the pressure part of the contact surface of the firing pin and the glue fluid is uniform, and the periphery of the contact part of the firing pin and the nozzle is consistent due to the flat head designed firing pin, the pressure intensity is uniform, the spraying effect is better, in other words, the flat firing pin is in seamless contact with the nozzle, so that the glue fluid pressure is balanced, the glue spraying effect is improved, and the gap is formed between the round firing pin and the nozzle, so that the glue fluid pressure is unbalanced and the pressure is easy to release, and the glue spraying effect is influenced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
the utility model relates to a firing pin structure of a dispenser, comprising: the injection valve comprises a striker 1, an impact part 2 of the striker, an injection valve body 3 and a nozzle 4, wherein the nozzle is installed at the lower end of the injection valve body, the impact part of the striker is flat-head-shaped, and the striker is installed in the injection valve body to move up and down so that the impact part of the striker impacts glue fluid to be sprayed out of the nozzle.
As shown in fig. 2 to 3, an injection valve apparatus of a dispenser, comprising: the injection valve comprises a firing pin 1, an impact part 2 of the firing pin, an injection valve body 3, a nozzle 4, a glue inlet mechanism 5, a glue inlet channel 6, a screw 7 and a motor 8, wherein the nozzle is installed at the lower end of the injection valve body, the glue inlet mechanism is fixedly connected with the injection valve body, the glue inlet channel is located in the glue inlet mechanism and communicated with the nozzle, the screw is arranged in the glue inlet channel in parallel, the screw is in transmission connection with the motor, the impact part of the firing pin is flat-head-shaped, and the firing pin is installed in the injection valve body and moves up and down to enable the impact part to impact glue fluid to be ejected out of the nozzle. Glue fluid is located into gluey passageway, and the motor rotation drives the screw rod and rotates, with glue fluid propelling movement to injection valve this internally, when the firing pin moves down, the striking part of its flat head form is strikeed to glue fluid, is spouted out through the nozzle by the glue fluid of striking to accomplish some glue operations, the screw rod pay-off has guaranteed that glue fluid is evenly delivered to and has waited to strike the region, the striking part of flat head form has guaranteed the homogeneity of striking pressure, it is better to glue the effect like this, and stability is good, and the precision is high.
According to the embodiment of the utility model, the impact part of the firing pin is designed into the flat head part, so that when the firing pin impacts the glue fluid, the stable and high-precision spraying of the glue fluid can be ensured when the viscosity of the glue fluid is high, and by utilizing the cavity pressure principle, because the contact surface of the firing pin of the round head ball round surface is overlarge, the viscous glue fluid contains powder particles which can jack up the peripheral part of the contact part of the firing pin and the nozzle to form a gap, the pressure part of the contact surface of the firing pin and the glue fluid is uniform, and the periphery of the contact part of the firing pin and the nozzle is consistent due to the flat head designed firing pin, the pressure is uniform, the spraying effect is better, in other words, the flat firing pin is in seamless contact with the nozzle, so that the glue fluid pressure is balanced, the glue spraying effect is improved, and the gap is formed between the round firing pin and the nozzle, so that the glue fluid pressure is unbalanced and the pressure is easy to release, and the glue spraying effect is influenced; feeding mechanism carries out the physics propelling movement that contacts for being equipped with the screw rod to glue fluid, and rotatory propelling movement has increased the continuity that the colloid flows, and is effectual to the high gluey fluid propelling movement of consistency, has also improved the stability and the precision of pay-off simultaneously for the effect is better to some glue.
The above description is only exemplary of the present invention and should not be taken as limiting the utility model, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
