Abstract
Description
Technical Field
[0001] This utility model relates to the field of dispensing valve technology, specifically to a piezoelectric valve and a dispensing machine using the piezoelectric valve. Background Technology
[0002] Chinese Patent Application No. 202410351396.8 discloses a syringe module and a dispensing device. The dispensing device includes a nozzle module. The syringe module includes a syringe body and a leak-proof valve. The syringe body has a cavity and an opening connecting to the cavity. The leak-proof valve includes a valve body and a leak-proof component. The valve body forms a dispensing channel and a dispensing port connecting to the dispensing channel. The valve body is connected to the syringe body, and the dispensing channel and the opening are connected. The leak-proof component is disposed in the dispensing channel to block or open the dispensing port. The syringe module has a blocked state (separated from the nozzle module) and an open state (connected to the nozzle module). In the blocked state, the leak-proof component blocks the dispensing port; in the open state, the nozzle module pushes the leak-proof component to open the dispensing port. The technical solution of this invention aims to automatically block the dispensing port after the syringe is separated during maintenance or parts replacement of the dispensing device, preventing media leakage, reducing work steps, and improving work efficiency.

[0009] Furthermore: the glue tube is fixedly installed on the fixing frame, and a check valve is installed on the glue outlet of the glue tube, which is detachably installed on the valve body.
[0010] Furthermore, a retaining ring is fixedly installed on the valve body.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0024] like Figures 1 to 3 As shown, a dispensing machine includes: a machine base 1, on which a material carrier 2 and a first linear module 3 are installed; a piezoelectric valve 4 for dispensing is installed on the first linear module, and the material carrier 2 is a belt conveyor for transporting materials.
[0025] The first linear module 3 is mounted on the second linear module 5, and the movement direction of the second linear module 5 is the same as the movement direction of the belt line. The second linear module 5 is mounted on the third linear module 6, and the movement direction of the third linear module 6 is perpendicular to the movement direction of the belt line.
[0026] The piezoelectric valve 4 includes: a valve body 7, a rubber sleeve 8, a fixed bracket 9, a first plug-in socket 10 fixedly installed on the fixed bracket 9, and a second plug-in socket 11 used in conjunction with the first plug-in socket 10. The valve body 7 is fixedly installed on the fixed bracket 9; the first plug-in socket 10 and the second plug-in socket 11 are used together to form a quick-release socket.
[0027] The glue cylinder 8 is used to supply glue to the valve body 7, and the plug-in seat 10 is fixedly connected to the moving part of the first linear module 3, so that the first linear module 3 can drive the piezoelectric valve 4 to move.
[0028] The glue tube 8 is fixedly installed on the mounting bracket, and a retaining ring 12 is fixedly installed on the valve body 7. A check valve 13 is installed on the glue outlet of the glue tube 8, and the check valve 13 is detachably installed on the valve body 7.
[0029] The check valve 13 and the valve body 7 are connected by a quick connector 14, meaning that pulling the check valve 13 upwards separates the rubber sleeve 8 from the valve body 7. The quick connector 14 is a CYTEC stainless steel hydraulic flat-panel CYFIT machine tool power tool quick connector. The retaining ring 12 is a semi-open retaining ring 12, and the fixing bracket can be locked inside the retaining ring 12. The retaining ring 12 is located at the upper part of the valve body 7, thereby fixing the fixing bracket from the top.
[0030] The quick-release socket is equipped with an electrical signal socket, which is an existing and mature design. In other words, the quick-release socket enables docking and fixation, and the electrical signal socket enables the connection of circuits and networks.
[0031] A placement rack 15 is fixedly installed on the machine base 1, and the rubber tube 8 and valve body 7 are placed on the placement rack 15; a robot arm 16 is installed on the machine base 1 for replacing the rubber tube 8 and / or the first plug-in socket 10 and the second plug-in socket 11.
[0032] Finally, it should be noted that a downward-pressing cylinder is installed on the first linear module. A moving part is connected to the piston rod of the downward-pressing cylinder, and a sealing plug and a gas valve are installed on the moving part. The gas valve is connected to a gas source. After the check valve 13 is inserted into the valve body 7, the downward-pressing cylinder drives the sealing plug to move downward, so that the sealing plug contacts the upper end of the glue cylinder 8 and seals the glue cylinder 8. Then, the gas valve injects gas into the glue cylinder 8, which on the one hand applies a certain amount of force to the check valve 13, so that the glue enters the valve body 7 through the check valve 13, and on the other hand, presses and fixes the glue cylinder 8 from the top.
[0033] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
