Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a quick-release flow channel assembly. Background Technology

[0002] The main structure of a piezoelectric valve consists of a valve body, a piezoelectric actuator housed within the valve body, an amplifier, and a flow channel assembly. The amplifier amplifies the deformation of the piezoelectric ceramic in the actuator after energization using a lever principle, transmitting this amplification to the jet push rod in the flow channel assembly. This jet push rod then sprays the adhesive from the flow channel assembly. The connection between the flow channel assembly and the valve body in piezoelectric valves is often a detachable structure to facilitate cleaning and replacement of the flow channels. Existing detachable connection structures for piezoelectric valves primarily use screws to fix the flow channel assembly to the valve body from below, which is cumbersome to disassemble and can easily damage internal structures such as the ejector pin during removal. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a quick-release flow channel assembly, which can not only achieve stable installation of the body with internal flow channels, but also allow for rotational disassembly and assembly of the body to avoid damage to the impact pin.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick-release flow channel assembly for a piezoelectric valve, comprising: a body having an inlet flow channel and an outlet flow channel respectively opened inside, and a nozzle mounted on the body; the lower end of the outlet flow channel, whose upper end is connected to the inlet flow channel, is connected to the nozzle; the lower end of the piezoelectric valve's striker pin passes through the outlet flow channel and cooperates with the nozzle; and further comprising: a mounting block mounted on the piezoelectric valve body, wherein a mounting groove for the body to be embedded is opened on the side surface of the mounting block, and a water-adhesive groove is opened on the side surface of the mounting block above or below the body. A mounting hole extending in a horizontal direction is provided, in which a pin is rotatably mounted. A guide hole communicating with the mounting hole is provided on the side wall of the mounting groove facing the main body. A limiting ball that can slide vertically between the pin and the main body is provided in the vertically extending guide hole. A first groove corresponding to the limiting ball is provided on the side surface of the main body. A second groove corresponding to the limiting ball is provided on the outer surface of the pin. When the limiting ball is located outside the second groove, the limiting ball embedded in the first groove is in abutting contact with the pin.

[0005] The following are further improvements to the above technical solution:

[0006] 1. In the above scheme, the other end of the pin, which is embedded in the mounting hole, has a wrench portion located on the outside of the mounting block.

[0007] 2. In the above scheme, the mounting block is installed on the lower end face of the piezoelectric valve body by at least two bolts.

[0008] 3. In the above scheme, the first groove is a quarter-spherical groove.

[0009] 4. In the above scheme, the second groove is an arc-shaped groove formed on the circumference of the pin portion.

[0010] 5. In the above solution, the lower surface of the body has a mounting protrusion, and the nozzle is mounted on the lower end face of the mounting protrusion via a mounting base.

[0011] 6. In the above scheme, the mounting base with internal threads and the mounting protrusion with external threads are connected by threads.

A guide hole communicating with the mounting hole is formed on the side wall of the mounting groove facing the main body. A limiting ball that can slide vertically between the pin and the main body is provided in the vertically extending guide hole. A first groove corresponding to the limiting ball is formed on the side surface of the main body, and a second groove corresponding to the limiting ball is formed on the outer surface of the pin. When the limiting ball is located outside the second groove, the limiting ball embedded in the first groove presses against the pin.

[0019] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0020] Example 1: A quick-release flow channel assembly for a piezoelectric valve, comprising: a body 1 having an inlet flow channel 41 and an outlet flow channel 42 respectively internally, and a nozzle 2 mounted on the body 1; the outlet flow channel 42, whose upper end communicates with the inlet flow channel 41, communicates with the nozzle 2 at its lower end; the lower end of the piezoelectric valve's striker 3 penetrates into the outlet flow channel 42 and cooperates with the nozzle 2; further comprising: a mounting block 7 mounted on the piezoelectric valve body; the mounting block 7 has a mounting groove 71 for the body 1 to be embedded in on its side surface; the mounting block 7 has a horizontally extending mounting hole 10 on its side surface, located above or below the body 1; and a pin 9 for... The mounting groove 71 is rotatably installed in the mounting hole 10. A guide hole 11 communicating with the mounting hole 10 is opened on the side wall of the mounting groove facing the body 1. A limiting ball 12 that can slide vertically between the pin 9 and the body 1 is provided in the vertically extending guide hole 11. A first groove 131 corresponding to the limiting ball 12 is opened on the side surface of the body 1. A second groove 132 corresponding to the limiting ball 12 is opened on the outer surface of the pin 9. When the limiting ball 12 is located outside the second groove 132, the limiting ball 12 embedded in the first groove 131 is in abutting contact with the pin 9.

[0021] Under normal operating conditions, the main body 1 is embedded in the mounting groove 71 of the mounting block 7. The lower end of the impact pin 3, which cooperates with the nozzle 2, penetrates into the glue dispensing channel 42. Through repeated impacts between the impact pin 3 and the nozzle 2, the glue in the glue dispensing channel 42 is sprayed outward from the lower end of the nozzle. At this time, the pin 9 is in the first position. A part of the limiting ball 12 located outside the second groove is embedded in the first groove 131 on the main body under the pressure of the pin 9, thereby realizing the connection between the main body 1 and the mounting block 7.

[0022] The other end of the pin 9, which is embedded in the mounting hole 10, has a wrench portion 91 located on the outside of the mounting block 7; the mounting block 7 is mounted on the lower end face of the piezoelectric valve body by at least two bolts; the first groove 131 is a quarter-spherical groove.

[0023] Example 2: A quick-release flow channel assembly for a piezoelectric valve, comprising: a body 1 having an inlet flow channel 41 and an outlet flow channel 42 respectively internally, and a nozzle 2 mounted on the body 1; the lower end of the outlet flow channel 42, whose upper end communicates with the inlet flow channel 41, communicates with the nozzle 2; the lower end of the piezoelectric valve's striker 3 penetrates into the outlet flow channel 42 and cooperates with the nozzle 2; further comprising: a mounting block 7 mounted on the piezoelectric valve body; a mounting groove 71 for the body 1 to be embedded in is formed on the side surface of the mounting block 7; a horizontally extending mounting hole 10 is formed on the side surface of the mounting block 7, located above or below the body 1; and a pin 9 for... The mounting groove 71 is rotatably installed in the mounting hole 10. A guide hole 11 communicating with the mounting hole 10 is opened on the side wall of the mounting groove facing the body 1. A limiting ball 12 that can slide vertically between the pin 9 and the body 1 is provided in the vertically extending guide hole 11. A first groove 131 corresponding to the limiting ball 12 is opened on the side surface of the body 1. A second groove 132 corresponding to the limiting ball 12 is opened on the outer surface of the pin 9. When the limiting ball 12 is located outside the second groove 132, the limiting ball 12 embedded in the first groove 131 is in abutting contact with the pin 9.

[0024] When it is necessary to disassemble the main body 1, firstly, rotate the pin 9 to the second position using the wrench part 91. At this time, the second groove 132 on the pin 9 faces the limiting ball 12. Then, rotate the main body 1 around the ejector pin 3 of the glue dispensing channel 42 until the main body 1 is rotated out of the mounting groove 71 of the mounting block 7. During this process, the limiting ball 12 moves into the second groove 132 on the pin 9 under the push of the main body 1, thereby losing its limiting effect on the main body 1 and allowing the main body 1 to rotate. Then, move the main body that has been rotated out of the mounting groove 71 downward until the disassembly is completed.

[0025] The second groove 132 is an arc-shaped groove formed on the circumference of the pin 9; the lower surface of the body 1 has a mounting protrusion 51, and the nozzle 2 is mounted on the lower end face of the mounting protrusion 51 by a mounting seat 52; the mounting seat 52 with internal threads and the mounting protrusion 51 with external threads are connected by threads.

[0026] Working principle:

[0027] It is generally used in conjunction with a piezoelectric ceramic piezoelectric valve and is fixedly installed on the lower end face of the piezoelectric valve body to which it is assembled by bolts and mounting blocks;

[0028] Under normal operating conditions, the main body is embedded in the mounting groove of the mounting block, and the lower end of the impact pin that cooperates with the nozzle enters the glue dispensing channel. Through repeated impacts between the impact pin and the nozzle, the glue in the glue dispensing channel is sprayed out from the lower end of the nozzle. At this time, the pin is in the first position, and part of the limiting ball located outside the second groove is embedded in the first groove on the main body under the action of the pin, thereby realizing the connection between the main body and the mounting block.

[0029] When it is necessary to disassemble the main body, first use the wrench to rotate the pin to the second position. At this time, the second groove on the pin faces the limiting ball. Then rotate the main body around the glue dispensing channel ejector pin until the main body is rotated out of the mounting slot of the mounting block. During this process, the limiting ball moves into the second groove on the pin under the push of the main body, thereby losing its limiting effect on the main body and allowing the main body to rotate. Then, move the main body that has been rotated out of the mounting slot downwards until the disassembly is completed.

[0030] The disassembled body and its nozzles can be cleaned.

[0031] When it is necessary to install the main body, simply perform the reverse operation of disassembly.

[0032] When using the above-mentioned quick-release flow channel assembly, it can not only achieve stable installation of the body with internal flow channels, but also allow for rotational disassembly and assembly of the body to avoid damage to the impact pin, and facilitate cleaning of the disassembled body.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
