Description
Technical Field
The invention belongs to the technical field of dispenser equipment, and particularly relates to an injection valve mechanism for a dispenser.
Background
In the existing dispensing machine, a jet valve is often adopted, and the glue fluid at the nozzle is ejected in a glue drop shape after being impacted by a firing pin at a high speed, so that the dispensing work process is completed. At present, a main injection valve adopts a piezoelectric reutilizing spring as a rebound device to control the up-and-down movement of a firing pin, namely the piezoelectric provides downward power for the firing pin (the firing pin impacts glue fluid to eject glue drops), and the spring provides upward power (the firing pin is reset), so that the sensitivity of the spring is not high in piezoelectric sensitivity (the sensitivity of the piezoelectric is usually in millisecond level), the power consumption of the spring is often caused, and a trip phenomenon is caused, for example, when the spring is rapidly moved up and down, the spring does not react when the spring is rapidly moved down, and when the spring is moved down for the second time, a gap is formed in the middle of the spring, so that the provided impact and reset power are not coordinated, and the injection effect is influenced; on the other hand, after the spring is used for a long time or for a plurality of times, the elasticity and the sensitivity can be greatly reduced, and the spring needs to be replaced in time to ensure the corresponding injection quality, so that the maintenance trouble is increased.
Disclosure of Invention
The embodiment of the invention aims to provide an injection valve mechanism for a dispenser, which adopts a double piezoelectric mode, can coordinate impact power and reset power supplied to a firing pin and ensure the injection effect.
The embodiment of the invention is realized as follows:
an injection valve mechanism for a dispenser comprising: the power device comprises a power device body, a first piezoelectric structure, a second piezoelectric structure, a lever and a vibration support column, wherein the first piezoelectric structure and the second piezoelectric structure are arranged inside the power device body, the vibration support column is arranged on the power device body, the lever is connected with the vibration support column and takes the lever as a lever fulcrum, the first piezoelectric structure is connected with one side of the lever, the second piezoelectric structure is connected with the other side of the lever, the first piezoelectric structure provides impact power for the striker through one side of the lever, and the second piezoelectric structure provides reset power for the striker through the other side of the lever.
One side of the lever is exposed outside the power device body, the other side of the lever is arranged inside the power device body, and the striker is connected with one side of the lever.
The embodiment of the invention provides impact power and reset power for the striker respectively by adopting a double piezoelectric mode, and because both sides use piezoelectric, the springs are removed, so that the sensitivities of both sides are ensured to be the same, the up-and-down power is more coordinated, the working efficiency and the working stability of the striker are improved, the up-and-down movement precision of the striker is improved, the precision can be adjusted to a required degree, and the ejection effect of the dispenser is ensured; the lever in the invention directly extends and places outside the power mechanism of the injection valve, namely the connection between the lever and the firing pin is exposed outside, thus increasing the visibility of the work and facilitating the maintenance of the firing pin.

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 invention and are not intended to limit the invention.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
as shown in fig. 1, an injection valve mechanism for a dispenser includes: the power device comprises a power device body 1, a first piezoelectric structure 3, a second piezoelectric structure 2, a lever 4 and a vibration support column 5, wherein the first piezoelectric structure and the second piezoelectric structure are arranged inside the power device body, the vibration support column is arranged on the power device body, the lever is connected with the vibration support column and takes the same as a lever fulcrum, the first piezoelectric structure is connected with one side of the lever, the second piezoelectric structure is connected with the other side of the lever, the first piezoelectric structure provides impact power for the striker through one side of the lever, and the second piezoelectric structure provides reset power for the striker through the other side of the lever. In the figure, the first piezoelectric structure 3 and the second piezoelectric structure 2 generally adopt a vibrating electromagnet to provide power, and the aim of reciprocating motion is achieved by utilizing the vibration of the electromagnet, the invention utilizes a lever principle, two ends of a lever respectively provide power through the piezoelectric structures, the force transmission of the lever is direct, when impact power needs to be provided, the force of the first piezoelectric structure 3 is applied to one side of the lever, the lever directly and rigidly drives a firing pin to move downwards to impact glue fluid to jet glue drops, when reset power needs to be provided, the force of the second piezoelectric structure 2 is applied to the other side of the lever, the lever directly and rigidly drives the firing pin to move upwards to reach a reset position, the forces of the first piezoelectric structure 3 and the second piezoelectric structure 2 are alternately applied to the lever to be in a seamless fit mode, the control precision depends on the control precision of the electromagnet (generally can reach millisecond level, even higher), compared with the spring in the prior art, the double-piezoelectric dispensing device is more accurate, and can better improve the dispensing precision and ensure the dispensing quality during high-speed dispensing, so that the double-piezoelectric power adopted by the invention ensures that the upper power and the lower power of the firing pins are coordinated and consistent, and the condition of gear jumping or gap spacing cannot exist.
One side of the lever is exposed outside the power device body, the other side of the lever is arranged inside the power device body, and the striker is connected with one side of the lever. Because the connection of the lever and the firing pin is exposed out of the power device body, the visual performance is more visual, the replacement of the firing pin or other maintenance is more convenient, and necessary maintenance can be quickly carried out on the equipment.
The embodiment of the invention provides impact power and reset power for the striker respectively by adopting a double piezoelectric mode, and because both sides use piezoelectric, the springs are removed, so that the sensitivities of both sides are ensured to be the same, the up-and-down power is more coordinated, the working efficiency and the working stability of the striker are improved, the up-and-down movement precision of the striker is improved, the precision can be adjusted to a required degree, and the ejection effect of the dispenser is ensured; the lever in the invention directly extends and places outside the power mechanism of the injection valve, namely the connection between the lever and the firing pin is exposed outside, thus increasing the visibility of the work and facilitating the maintenance of the firing pin.
The above description is only exemplary of the present invention and should not be taken as limiting the invention, 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.
