Detailed Description
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
Referring to fig. 1 to 3, in an embodiment of the present invention, a flexible lamp strip multi-path continuous dispensing valve includes a glue tank 4, a resorption type hydraulic valve 1 is disposed above the glue tank 4, and the resorption type hydraulic valve 1 is communicated with the glue tank 4 through a double external thread connector 2; glue jar 4's bottom end face intermediate position has seted up the glue chamber, and 4 bottoms of glue jar pass through bolt fixedly connected with throttle plate 6, and bolt fixedly connected with syringe needle mounting panel 8 is passed through to throttle plate 6 bottom, and syringe needle mounting panel 8 bottom face is equipped with a plurality of syringe needles 9 along its length direction, and syringe needle 9 and glue chamber intercommunication. When this application can carry out continuous point and glue, can also divide into multichannel point all the way evenly.
In this embodiment: a first sealing ring 5 is embedded between the glue tank 4 and the throttle plate 6 and around the bottom end of the glue cavity. The first seal ring 5 can improve the sealing performance between the glue tank 4 and the throttle plate 6.
In this embodiment: a second sealing ring 7 is embedded between the throttle plate 6 and the needle mounting plate 8. The second seal 7 improves the seal between the throttle plate 6 and the needle mounting plate 8.
In this embodiment: the top end of one side surface of the glue tank 4 is fixedly connected with a glue tank cushion block 3 through a screw. The glue pot cushion block 3 can be used for conveniently installing the glue dispensing valve on the glue dispensing machine.
In this embodiment: vertical cavity channels are formed in the throttle plate 6 corresponding to the positions of the point needles 9, and the point needles 9 are communicated with the glue cavities through the vertical cavity channels. The vertical cavity is the shortest and fastest way for the glue to flow to the needle 9.
In this embodiment: the point needle 9 is connected with the bottom end surface of the needle mounting plate 8 in a threaded manner and can be detached. This arrangement facilitates subsequent inspection or replacement of the point needle 9.
In this embodiment: the glue injection mechanism is connected with the resorption formula hydrovalve 1 and used for injecting glue into the resorption formula hydrovalve 1.
In this embodiment: injecting glue mechanism specifically includes: the method specifically comprises the following steps: screw pump 11 and step motor 15 are connected with glue injection pipe 10 between screw pump 11 and the resorption formula hydrovalve 1, and screw pump inlet 12 has been seted up on screw pump 11 top and has been used for leading-in glue, and 11 one end fixedly connected with motor mount pad 13 of screw pump, 13 side fixedly connected with speed reducer 14 of motor mount pad, and the accordant connection between speed reducer 14 and the step motor 15. When the screw pump is used, the stepping motor 15 is used as a power source and drives the screw pump 11 through the speed reducer 14. Glue is stored in an external tank body and flows to the screw pump 11 from the screw pump glue inlet 12 through air pressure, the screw pump 11 rotates to enable the glue in the pipeline to generate pressure, and the pressure flows into the resorption type hydraulic valve 1 through the glue injection pipe 10.
The working principle of the invention is as follows: during the use, at first, through injecting glue mechanism to the inside injection glue of resorption formula hydrovalve 1, glue accessible two external screw thread joint 2 gets into glue jar 4, and glue jar 4 is separated by first sealing washer 5 and throttle plate 6, can effectively avoid glue excessive. It should be noted that, according to the pascal principle: when the external pressure p0 of the liquid in the closed container is changed, the pressure at any point in the liquid is changed by the same magnitude as long as the original static state of the liquid is still kept. That is, in a closed container, the pressure applied to the stationary liquid will be transmitted to each point at the same time in equal value. The dispensing valve is designed into a large closed cavity, one path of inlet and the outlet can be designed into a plurality of outlets (corresponding to a plurality of needle heads 9), so that the pressure of each outlet is equal, namely the glue outlet amount of each outlet is equal; therefore, as long as the glue amount at the inlet is continuously provided, the glue amount at the outlets is not broken, and continuous gluing is realized. The structure of the rubber valve is greatly simplified by the design, so that the processing difficulty is reduced, and the cost is reduced. In addition, in the process that glue flows into the dispensing needle 9 from the vertical cavity of the glue tank 4, the glue is separated by the second sealing ring 7 to avoid the glue from overflowing, the glue tank 4 uniformly flows the glue to the dispensing needle 9 for continuous dispensing, when the dispensing is finished, the screw pump 11 stops transferring, and the resorption type hydraulic valve 1 acts to generate a reverse suction force so as to ensure that the glue stops rapidly.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
