Description
Technical Field
The utility model belongs to the technical field of the point gum machine equipment, especially, relate to an injection valve mechanism for point gum machine.
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.
SUMMERY OF THE UTILITY MODEL
An object of the embodiment of the utility model is to provide an injection valve mechanism for point gum machine adopts two piezoelectricity modes, can make the striking power of offering the firing pin and the power coordination unanimity that resets, guarantees to spray the effect.
The embodiment of the utility model provides a realize like this:
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 utility model provides a through adopting the mode of two piezoelectricity to provide striking power and reset power respectively to the firing pin, because both sides all use piezoelectricity, remove the spring, guarantee that the sensitivity of both sides is all the same, make upper and lower power more harmonious, improve the work efficiency, the job stabilization nature of firing pin to and improve the precision of firing pin up-and-down motion, make the precision adjustable to required degree, guaranteed the injection effect of point gum machine; the utility model provides an outside that injection valve power mechanism was put to the direct extension of lever, the lever is connected with the firing pin promptly and is exposed outside, has increased the visuality of work, and the convenience is maintained and is maintained the firing pin.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in 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 is given to specific implementations of the present invention with reference to 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 vibration of the electromagnet is utilized to achieve the purpose of reciprocating motion, the utility model utilizes the lever principle, the two ends of the lever respectively provide power through the piezoelectric structures, the force transmission of the lever is direct, when impact power is required to be provided, the force of the first piezoelectric structure 3 is applied to one side of the lever, at the moment, the lever directly and rigidly drives the striker to move downwards to impact glue fluid to jet glue drops, when reset power is required to be provided, the force of the second piezoelectric structure 2 is applied to the other side of the lever, at the moment, the lever directly and rigidly drives the striker to move upwards to reach the reset position, the forces of the first piezoelectric structure 3 and the second piezoelectric structure 2 are alternately applied on the lever to be in a seamless fit way, the control precision depends on the control precision of the electromagnet (generally can reach millisecond level, even higher), for prior art's spring, more accurate, when high-speed point is glued, the quality of gluing is guaranteed to the precision that can better improvement point, consequently the utility model discloses a two piezoelectricity power, power coordination is unanimous about having guaranteed the firing pin, can not have the condition of jumping shelves or clearance interval.
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 utility model provides a through adopting the mode of two piezoelectricity to provide striking power and reset power respectively to the firing pin, because both sides all use piezoelectricity, remove the spring, guarantee that the sensitivity of both sides is all the same, make upper and lower power more harmonious, improve the work efficiency, the job stabilization nature of firing pin to and improve the precision of firing pin up-and-down motion, make the precision adjustable to required degree, guaranteed the injection effect of point gum machine; the utility model provides an outside that injection valve power mechanism was put to the direct extension of lever, the lever is connected with the firing pin promptly and is exposed outside, has increased the visuality of work, and the convenience is maintained and is maintained the firing pin.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
