[0035] This utility model provides a dispensing regulating valve 100. For details, please refer to [link to relevant documentation]. Figures 1 to 3 In this embodiment, the dispensing regulating valve 100 includes a valve body 1, a dispensing structure 2, a first regulating structure 3, and a second regulating structure 4. The valve body 1 has an upper valve chamber, a lower valve chamber, and a transfer chamber connecting the upper valve chamber and the lower valve chamber. The dispensing structure 2 includes a guide impact rod 21 movably disposed in the lower valve chamber and a transmission member with one end abutting against the guide impact rod 21. The other end of the guide impact rod 21 is adapted to extend into the dispensing port. The first regulating structure 3 is disposed in the transfer chamber and has a first connecting member arranged opposite to it. The first connecting end and the second connecting end are connected together. The second connecting end abuts against the transmission member and has a travel distance that moves closer to or away from the first connecting end. The second connecting end moves to drive the transmission member, so that the transmission member can act on the guide impact rod 21 and drive the guide impact rod 21 to move closer to or away from the dispensing port. The second adjusting structure 4 is disposed in the upper valve cavity and connected to the first connecting end. The second adjusting structure 4 can adjust the position of the first connecting end to drive the second connecting end to move closer to or away from the transmission member.

[0036] In this embodiment, the valve body 1 is provided with an upper valve chamber, a lower valve chamber, and a transfer chamber. The second adjustment structure 4, the first adjustment structure 3, and the dispensing structure 2 are respectively disposed in each chamber. The guide impact rod 21 of the dispensing structure 2 is used to extend into the dispensing port to press the adhesive out of the dispensing port for dispensing. The travel distance of the guide impact rod 21 can be adjusted by the first adjustment structure 3. The second connecting end of the first adjustment structure 3 abuts against the transmission component, thereby fixing the position of the transmission component and adjusting the position of the guide impact rod 21 to adjust the dispensing amount. Moreover, during the dispensing process, the second connecting end can move relative to the first connecting end. The first adjustment structure 3 can be automatically compensated for during the dispensing process, thereby ensuring the stability of the dispensing volume of the dispensing regulating valve 100 during dispensing. Moreover, the second adjustment structure 4 can act on the first adjustment structure 3. When the position of the guide impact rod 21 changes, the position of the first connecting end of the first adjustment structure 3 can be adjusted by the second adjustment structure 4, thereby adjusting the position of the second connecting end. This allows the second connecting end to act on the transmission component, thereby adjusting the position of the guide impact rod 21. This allows the guide impact rod 21 to return to the position with an appropriate dispensing volume, making the adjustment of the dispensing volume of the guide impact rod 21 more convenient and thus improving work efficiency.

[0037] The valve body 1 is generally square in shape. The upper valve chamber, the lower valve chamber and the transfer chamber are arranged sequentially on the valve body 1 in the vertical direction. The second adjustment structure 4, the first adjustment structure 3 and the glue dispensing structure 2 are arranged sequentially in the vertical direction.

[0038] Combination Figure 2 and Figure 3As shown, a through hole is provided between the upper valve chamber and the intermediate transfer chamber; the first adjusting structure 3 includes a mounting block 31, a first connecting block 32, and a second connecting block 33. The mounting block 31 is engaged in the through hole and can move slightly in the vertical direction relative to the through hole without dislodging itself. The first connecting block 32 is located at the bottom of the mounting block 31, the second adjusting structure 4 is pressed against the top of the mounting block 31, and the second connecting block 33 is located at the bottom of the first connecting block 32 and abuts against the transmission member. The first connecting end is formed on the mounting block 31, and the second connecting end is formed at the end of the second connecting block 33 away from the first connecting block 32. Both the first connecting block 32 and the second connecting block 33 are generally square in shape. The second connecting block 33 is elongated and extends vertically, with the length of the second connecting block 33 being greater than the length of the first connecting block 32. The second connecting block 33 abuts against the transmission component, and the position of the mounting block 31 is adjusted by the second adjusting structure 4, so that the position of the second connecting block 33 can be relatively changed in the vertical direction, thereby pressing against the transmission component to adjust the position of the guide impact rod 21, making the position adjustment of the guide impact rod 21 more convenient.

[0039] Furthermore, both the first connecting block 32 and the second connecting block 33 are deformable, and the deformation of the first connecting block 32 and the deformation of the second connecting block 33 are complementary, so that the total length of the first connecting block 32 and the second connecting block 33 remains unchanged. This makes the first connecting block 32 and the second connecting block 33 less susceptible to the influence of working temperature rise during the operation of the dispensing regulating valve 100, and keeps the position of the transmission component unchanged. Therefore, it can better ensure that the dispensing amount of the dispensing regulating valve 100 remains consistent during the operation.

[0040] Regarding the second adjustment structure 4, combined with Figure 2 and Figure 3As shown, the second adjustment structure 4 includes an adjustment screw 41 and a first transmission rod 42. The adjustment screw 41 is screwed onto the valve body 1 and is at least partially movable up and down relative to the valve body 1. The first transmission rod 42 has a first rotating part rotatably connected to the valve body 1 and a first abutting part on one side. The first abutting part abuts against the mounting block 31. The adjustment screw 41 abuts against the other side of the first transmission rod 42. The adjustment screw 41 and the first abutting part are both located on the same side of the first rotating part. When the adjusting screw 41 is subjected to an external force, such as by manually rotating the adjusting screw 41, at least a portion of the adjusting screw 41 can move relative to the valve body 1 in the vertical direction to move towards a direction that is away from the first transmission rod 42. This allows the first transmission rod 42 to press against the mounting block 31, causing the mounting block 31 to move downwards, or allows at least a portion of the adjusting screw 41 to move upwards away from the first transmission rod 42, causing the first transmission rod 42 to move away from the mounting block 31. This allows the mounting block 31 to move upwards under the reverse force of the transmission member, thereby adjusting the position of the guide impact rod 21.

[0041] Furthermore, such as Figure 3 As shown, the adjusting screw 41 includes an adjusting handle 411 and an adjusting stud 412 connected to the adjusting handle 411. One end of the adjusting handle 411 protrudes from the valve body 1, and the other end of the adjusting handle 411 is connected to the adjusting stud 412. The adjusting handle 411 rotates relative to the valve body 1, causing the adjusting stud 412 to rotate as well. Under the screwed connection between the adjusting stud 412 and the valve body 1, the adjusting stud 412 is moved relative to the adjusting handle 411, allowing it to move towards or away from the first transmission rod 42.

[0042] The adjusting handle 411 extends outside the valve body 1 for easy manual gripping. The adjusting handle 411 is generally cylindrical, and the portion extending outside the valve body 1 may have a concave-convex structure to increase friction and facilitate adjustment. The other side of the adjusting handle 411 is located inside the valve body 1 to connect with the adjusting stud 412. By adjusting the rotation of the adjusting handle 411, the adjusting stud 412 rotates accordingly, allowing it to move vertically relative to the valve body 1. This activates the first transmission rod 42, thereby adjusting the first adjusting structure 3 and the dispensing structure 2 to better regulate the dispensing volume.

[0043] The first transmission rod 42 extends laterally, specifically along the left-right direction of the valve body 1. The left end of the first transmission rod 42 is rotatably connected to the valve body 1 via a first cylindrical pin, which abuts against the upper part of the first transmission rod 42. The first abutting portion includes an abutting protrusion located at the lower part of the first transmission rod 42. The adjusting stud 412 abuts against the right end of the first transmission rod 42. The adjusting stud 412 abuts against the first transmission rod 42, causing it to rotate around the first cylindrical pin, thereby allowing the abutting protrusion to move closer to or further away from the mounting block 31. Furthermore, the abutting protrusion and the adjusting stud 412 are located on the same side of the first cylindrical pin, thus reducing the effective distance to the mounting block 31 and enabling better and more precise adjustment of minute displacements.

[0044] Among them, such as Figure 3 As shown, the adjusting handle 411 has an opening groove at one end located inside the valve body 1, with the opening of the groove facing downwards. The adjusting stud 412 extends along the vertical direction of the valve body 1, with one end engaged in the opening groove and the other end having an external thread on its outer peripheral side. The valve body 1 has an internal thread, and the external thread is screwed into the internal thread. The adjusting handle 411 is configured to rotate relative to the valve body 1 but not move vertically relative to the valve body 1. Specifically, a limiting groove is provided on the section of the adjusting handle 411 located inside the valve body 1, and the valve body 1 has a receiving groove corresponding to the limiting groove. The second adjusting structure 4 also includes a locking block, which is engaged in the limiting groove and the receiving groove, thereby restricting the vertical movement of the adjusting handle 411 while ensuring that the adjusting handle 411 can rotate relative to the valve body 1. The adjusting handle 411 drives the adjusting stud 412 to rotate. Under the action of the external thread and the internal thread, the adjusting stud 412 can move in the vertical direction relative to the valve body 1, thereby adjusting the pressing depth of the adjusting stud 412 on the first transmission rod 42. This causes the position of the first adjusting structure 3 in the vertical direction to change, which in turn causes the position of the guide impact rod 21 in the vertical direction to change, thus changing the amount of glue dispensed. Adjusting the amount of glue dispensed is simpler and more convenient.

[0045] Furthermore, the end face of the adjusting stud 412 facing the first transmission rod 42 is arc-shaped. A line-to-surface contact is formed between the first transmission rod 42 and the adjusting stud 412, making the effect of the adjusting stud 412 on the first transmission rod 42 more significant, thereby enabling better adjustment of minute distances.

[0046] In one embodiment, combined with Figure 2 and Figure 3 As shown, the dispensing regulating valve 100 also includes a base 5 located at the bottom of the valve body 1. A glue storage chamber 51 is provided on the base 5, which is in communication with the lower valve chamber. The glue outlet is located at the bottom of the glue storage chamber 51. The guide impact rod 21 can extend into the glue storage chamber 51 to squeeze the glue out from the glue outlet. A glue storage cylinder can be connected to one side of the glue storage chamber 51. The glue in the storage cylinder can flow from the guide channel to the glue outlet and be squeezed out through the guide impact rod 21.

[0047] Moreover, such as Figure 3 As shown, a nozzle 52 is also provided on the bottom of the base 5, corresponding to the glue outlet. Glue from the glue outlet can flow to the nozzle 52 and out through it. The glue dispensing regulating valve 100 also includes a glue dispensing nut 6 screwed onto the outside of the nozzle 52. The glue dispensing nut 6 has a spray nozzle communicating with the glue outlet. At least a portion of the guide impact rod 21 can move into the nozzle 52 to squeeze the glue out of the spray nozzle. The glue dispensing nut 6 locks the glue outlet and facilitates disassembly and cleaning of the glue outlet.

[0048] The transmission component includes a second transmission rod 22, which has a second rotating portion rotatably connected to the valve body 1. A guide impact rod 21 abuts against a first side of the second transmission rod 22, and a second connecting end abuts against a second side of the second transmission rod 22. The first and second sides are arranged opposite to each other, and the guide impact rod 21 and the second connecting end are both located on the same side of the second rotating portion. The second rotating portion includes a second cylindrical pin, which abuts against the bottom of the second transmission rod 22 and is located near its left end. The right end of the second transmission rod 22 presses against the guide impact rod 21. A second connecting block 33 presses against the upper side of the second transmission rod 22 and is located on the same side of the guide impact rod 21 as the second cylindrical pin, thereby facilitating adjustment of the position of the guide impact rod 21.

[0049] The dispensing regulating valve 100 provided by this utility model can squeeze glue out for dispensing through the dispensing structure 2. During the dispensing process, the position of the guide impact rod 21 can be adjusted in real time through the first regulating structure 3 to ensure the consistency of the dispensing amount. Moreover, before dispensing begins, the position of the first regulating structure 3 can be adjusted through the second regulating structure 4, thereby realizing the adjustment of different dispensing amounts. This makes the dispensing more stable and reliable, and the adjustment of the dispensing amount simpler and more convenient.
