Description

Technical Field

[0001] The utility model relates to the field of dispensing valves, and more specifically, to a quick-release dual piezoelectric ceramic dispensing valve. Background Art

[0002] As an indispensable device in the precision manufacturing process, the unobstructed flow channel of the dispensing valve is crucial for ensuring the stability of the production line and the product quality.

[0003] However, one of the common problems in practical applications is that the flow channel is prone to blockage, which may be caused by various factors such as glue curing, impurity accumulation, or unreasonable design. Frequent blockages not only affect production efficiency but also increase maintenance costs and downtime. More inconveniently, the existing flow channel designs generally use screw locking to fix on the floor, and this fastening method is particularly cumbersome and time-consuming when the flow channel needs to be cleaned or replaced. The disassembly process usually requires professional tools, and due to space limitations and the possible concealment of screw positions, the operation is quite inconvenient.

[0004] Therefore, it is necessary to make further improvements in the existing technology. Summary of the Utility Model

[0092] The quick-release dual piezoelectric ceramic dispensing valve according to an embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0093] Refer to Figures 1 to 9 As shown, the quick-release dual piezoelectric ceramic dispensing valve according to an embodiment of the present utility model includes a bottom plate 10, a valve body 20, a flow channel assembly 30, a driving assembly 40, a locking assembly 50 and a glue feeding device 60.

[0094] The bottom plate 10 is adapted to be mounted on a machine table.

[0095] The valve body 20 is fixed to one end of the bottom plate 10. A flow channel pressing plate 201 is provided at the end of the valve body 20, and an installation gap is formed between the flow channel pressing plate 201 and the end face of the valve body 20.

[0096] The flow channel assembly 30 is provided at one end of the valve body 20, and one end thereof is inserted into the installation gap. A dispensing head 301 is provided in the middle of the flow channel assembly 30, and a plunger 302 is provided on the dispensing head 301. One end of the plunger 302 extends into the dispensing head 301 to block the inside of the dispensing head 301, and a locking groove 303 is provided on the surface of the flow channel assembly 30.

[0097] The driving assembly 40 is provided inside the valve body 20, and one end thereof is connected to the other end of the plunger 302 to drive the plunger 302 to move to control the opening and closing of the dispensing head 301. When the plunger 302 moves downward, the channel inside the dispensing head 301 can be closed. When the plunger 302 moves upward, the internal channel of the dispensing head 301 can be opened. It should be noted that the lower end of the plunger 302 is a conical structure, and the bottom of the internal channel of the dispensing head 301 is also a conical structure that matches the lower end of the plunger 302, so that the plunger 302 can close the inside of the dispensing head 301 when moving downward to prevent the glue from flowing out.

[0098] The locking assembly 50 is provided at one end of the valve body 20 and can be switched between a first state and a second state. When the locking assembly 50 is in the first state, one end of the locking assembly 50 is inserted into the locking groove 303 to lock the flow channel assembly 30 in the installation gap. When the locking assembly 50 is in the second state, one end of the locking assembly 50 moves out of the locking groove 303.

[0099] The glue feeding device 60 is provided at the other end of the bottom plate 10 and can slide along the length direction of the bottom plate 10. One end of the glue feeding device 60 is communicated with the flow channel assembly 30 to convey glue into the flow channel assembly 30 and flow out through the dispensing head 301. The glue feeding device 60 can automatically inject glue, and the glue inside it can be a single type of glue or a mixed AB glue, etc.

[0100] Based on the above, by setting the flow channel pressing plate 201, an installation gap is formed between the valve body 20 and the flow channel pressing plate 201 to facilitate the installation and insertion of one end of the flow channel assembly 30. Then, by inserting one end of the locking assembly 50 into the locking groove 303, the flow channel assembly 30 can be fixed in the installation gap. When the locking assembly 50 is switched to the second state, the end of the locking assembly 50 will move out of the locking groove 303. At this time, the flow channel assembly 30 can be directly pulled out of the installation gap. Its disassembly method is simple, fast, time-saving and labor-saving, which is beneficial to the quick disassembly and assembly of the flow channel assembly 30 during the production process.

[0101] Preferably, in an embodiment of the present invention, the locking assembly 50 includes a pressing rod 501 and a driving member 502.

[0102] One end of the valve body 20 is provided with a first installation groove 202, the pressing rod 501 is arranged in the first installation groove 202 and can move along the length direction of the first installation groove 202;

[0103] The driving member 502 is pivotally arranged on the side surface of the valve body 20, and one end extends into the first installation groove 202 and is connected to the pressing rod 501;

[0104] Wherein, when the driving member 502 pivots, it can drive the pressing rod 501 to move along the length direction of the first installation groove 202.

[0105] Thus, since the driving member 502 is pivotally arranged on the side surface of the valve body 20, and one end extends into the first installation groove 202 and is connected to the pressing rod 501, and when the driving member 502 pivots, it can drive the pressing rod 501 to move along the length direction of the first installation groove 202. Then, when it is necessary to disassemble the flow channel assembly 30, the driving member 502 can be rotated to drive the pressing rod 501 to move out of the locking groove 303 (i.e., the aforementioned second state). At this time, the flow channel assembly 30 can be directly pulled out, making the disassembly more simple and fast.

[0106] Preferably, in an embodiment of the present invention, the driving member 502 includes a driving shaft 5021 and a gear 5022.

[0107] A second installation groove 203 is provided on the side surface of the valve body 20, the second installation groove 203 is communicated with the first installation groove 202, and the driving shaft 5021 is rotatably arranged in the second installation groove 203.

[0108] The gear 5022 is sleeved on the driving shaft 5021 and is located in the first installation groove 202. A plurality of tooth grooves 5011 are provided at the relative position between the side surface of the pressing rod 501 and the gear 5022, and the plurality of tooth grooves 5011 are meshed with the gear 5022.

[0109] Thus, by providing a plurality of tooth grooves 5011 at the relative position between the side surface of the pressing rod 501 and the gear 5022, and the plurality of tooth grooves 5011 are meshed with the gear 5022. Then, when the driving shaft 5021 is rotated, the gear 5022 can be driven to rotate, and further drive the pressing rod 501 to move. The transmission through the gear 5022 makes the driving more stable and reliable, effectively avoiding the reduction of the driving effect caused by the wear of the driving shaft 5021.

[0110] Preferably, in an embodiment of the present utility model, it further includes a driving handle 5023, and the driving handle 5023 is arranged at the end of the driving shaft 5021 and located on the outer side surface of the valve body 20.

[0111] It can be understood that, in order to make the rotation of the driving shaft 5021 more convenient and labor-saving, the driving handle 5023 and the end of the driving shaft 5021 are perpendicular (of course, it can also be set to form an angle of 60° to 120° with the axis of the driving shaft 5021 according to requirements). In this way, the operator can rotate the driving shaft 5021 through the driving handle 5023, and its rotation is more convenient and labor-saving.

[0112] Preferably, in an embodiment of the present utility model, the first installation groove 202 includes a first groove section 2021 and a second groove section 2022. The diameter of the first groove section 2021 is larger than that of the second groove section 2022, so as to form a first step surface 2023 at the connection of the first groove section 2021 and the second groove section 2022. A second step surface 2024 is formed at one end of the outer surface of the extrusion rod 501.

[0113] A return spring 503 is sleeved on the extrusion rod 501. One end of the return spring 503 abuts against the first step surface 2023, and the other end abuts against the second step surface 2024.

[0114] In this way, since one end of the return spring 503 abuts against the first step surface 2023 and the other end abuts against the second step surface 2024, then, when the operator rotates the driving handle 5023 to make the locking assembly 50 in the second state, the return spring 503 is in a contracted state. When the operator releases the force applied to the driving handle 5023 by hand, the elastic force of the return spring 503 can drive the extrusion rod 501 to reset, that is, to make the entire locking assembly 50 return to the first state.

[0115] Preferably, in an embodiment of the present utility model, the driving assembly 40 includes a piezoelectric ceramic housing 401, a first piezoelectric ceramic assembly 402, a second piezoelectric ceramic assembly 403, a movable block 404 and a rotating shaft 405.

[0118] The second piezoelectric ceramic assembly 403 is arranged inside the piezoelectric ceramic housing 401, and the second piezoelectric ceramic assembly and the first piezoelectric ceramic assembly 402 are arranged at intervals.

[0119] One end of the movable block 404 is arranged inside the piezoelectric ceramic housing 401, the other end of the movable block 404 is connected to the firing pin 302, and the ends of the first piezoelectric ceramic assembly 402 and the second piezoelectric ceramic assembly 403 are both in contact with the movable block 404.

[0120] The rotating shaft 405 is installed inside the piezoelectric ceramic housing 401. An arc-shaped groove 4041 is provided at the contact position between the movable block 404 and the rotating shaft 405. The rotating shaft 405 is arranged inside the arc-shaped groove 4041. The first piezoelectric ceramic assembly 402 and the second piezoelectric ceramic assembly 403 are used to drive the movable block 404 to rotate around the rotating shaft 405 as the axis, so as to drive the firing pin 302 to move up and down.

[0121] In this way, since the arc-shaped groove 4041 is provided at the contact position between the movable block 404 and the rotating shaft 405, and the rotating shaft 405 is arranged inside the arc-shaped groove 4041, then, the first piezoelectric ceramic assembly 402 and the second piezoelectric ceramic assembly 403 can be used to squeeze and push different positions of the movable block 404, so that the movable block 404 rotates along the axis of the rotating shaft 405, so as to drive the firing pin 302 to move, so as to achieve the effect of closing and opening the dispensing head 301. Its overall structure is simple, the driving method is simple, and the control accuracy is higher through the control method of the piezoelectric ceramic, which is more conducive to controlling the glue output of the dispensing head 301.

[0122] Preferably, in an embodiment of the present invention, a first protrusion 4042 and a second protrusion 4043 are provided on a side surface of the movable block 404 facing away from the arc-shaped groove 4041. The first protrusion 4042 and the second protrusion 4043 are respectively located on both sides of the arc-shaped groove 4041;

[0123] The end of the first piezoelectric ceramic assembly 402 abuts against the first protrusion 4042, and the end of the second piezoelectric ceramic assembly 403 abuts against the second protrusion 4043.

[0124] It can be understood that since the first protrusion 4042 and the second protrusion 4043 are respectively located on both sides of the arc-shaped groove 4041, that is, on both sides of the rotating shaft 405, then, by squeezing and pushing the first protrusion 4042 or the second protrusion 4043 by the first piezoelectric ceramic assembly 402 and the second piezoelectric ceramic assembly 403, the movable block 404 can be made to rotate correspondingly along the axis of the rotating shaft 405 (the first piezoelectric ceramic assembly and the second piezoelectric ceramic assembly 403 are not driven simultaneously).

[0125] Preferably, in an embodiment of the present utility model, a connection groove 4044 is provided on the end face of the other end of the movable block 404. The connection groove 4044 is in a "cross" shape. A limiting piece 3021 is provided at the end of the ejector pin 302. The limiting piece 3021 is arranged in the horizontal part of the connection groove 4044, and the ejector pin 302 is arranged in the vertical part of the connection groove 4044.

[0126] In this way, since the connection groove 4044 is in a "cross" shape and is located on the end face of the movable block 404, and the limiting piece 3021 is arranged in the horizontal part of the connection groove 4044, that is, when the movable block 404 pivots along the axis of the rotating shaft 405, the ejector pin 302 can be driven to move. When the runner assembly 30 is disassembled, the end of the ejector pin 302 and the limiting piece 3021 can be directly removed from the connection groove 4044, making its disassembly more convenient and fast.

[0127] Preferably, in an embodiment of the present utility model, the glue feeding device 60 includes a bracket 601 and a glue barrel 602.

[0128] One end of the bracket 601 is slidably connected to the bottom plate 10.

[0129] The glue barrel 602 is arranged through the other end of the bracket 601. A glue pipe is connected to the end of the glue barrel 602, and the end of the glue pipe is communicated with the runner assembly 30.

[0130] In this way, since one end of the bracket 601 is slidably connected to the bottom plate 10, then when it is necessary to separate the glue pipe from the runner assembly 30, the bracket 601 can be moved to the side away from the runner assembly 30, so that the end of the glue pipe is away from the runner assembly 30.

[0131] Preferably, in an embodiment of the present utility model, a locking member 603 is provided on the side of one end of the bracket 601 for locking and fixing the position of the bracket 601.

[0132] In this way, by providing the locking member 603 on the side of one end of the bracket 601, the position of the bracket 601 can be locked and fixed to prevent it from moving randomly.
