Referring to fig. 1 and 2, the glue outlet valve 100 of the present embodiment is used for outputting glue. This play glue valve 100 includes: valve body 101, piston portion 103, play gluey head 102 and regulating part 200. A chamber 107 is provided in the valve body 101. The dispensing head 102 is mounted to the valve body 101 and communicates with the chamber 107. Piston portion 103 is received within chamber 107. The piston portion 103 has a striker 108, and a distal end (lower end in the drawing) of the striker 108 is opposed to the glue discharging head 102. As piston 103 is driven, striker 108 reciprocates in cavity 107 in the axial direction (vertical direction in the drawing) of cavity 107 to abut against glue dispensing head 102 or to move away from glue dispensing head 102. The adjustment portion 200 adjusts the striker 108 or the glue outlet 102 in the axial direction to adjust the distance between the distal end of the striker 108 and the glue outlet 102 in a state where the distal end of the striker 108 is away from the position of the glue outlet 102.

According to the glue dispensing valve 100 of the present embodiment, the switching frequency can be adjusted. Specifically, in the glue dispensing valve 100 of the present embodiment, the adjustment portion 200 is provided, and the distance between the distal end of the striker 108 and the glue dispensing tip 102 is adjusted by the adjustment portion 200 in a state where the distal end of the striker 108 is away from the position of the glue dispensing tip 102, whereby the stroke of the striker 108 from the position away from the glue dispensing tip 102 to the position abutting against the glue dispensing tip 102 can be changed, and thereby the time required for the striker 108 to close the glue dispensing tip 102 can be changed, for example, when the stroke of the striker 108 from the position away from the glue dispensing tip 102 to the position abutting against the glue dispensing tip 102 becomes large, the time required for the striker 108 to close the glue dispensing tip 102 becomes long; when the stroke of the striker 108 from the position away from the dispensing head 102 to the position abutting the dispensing head 102 becomes small, the time required for the striker 108 to close the dispensing head 102 becomes short. This can change the frequency of switching (opening or closing) the glue dispensing head 102.

The valve body 101 of the present embodiment may include, for example, a first valve seat 109 and a second valve seat 110, and the second valve seat 110 is sealingly attached to the first valve seat 109 from above. The cavity 107 of the valve body 101 comprises a power cavity 111 and a receiving cavity 104 for receiving glue. The first valve seat 109 and the second valve seat 110 together form a power chamber 111 located in the upper portion of the valve body 101. The first valve seat 109 and the glue outlet head 102 together form a receiving cavity 104. The piston portion 103 includes a piston 112 and a striker 108, with one end of the striker 108 mounted to the piston 112. Further, the upper end of the striker 108 protrudes above the piston 112. A piston 112 is housed in the power chamber 111. Further, a spring member 113 is accommodated in the power chamber 111, and one end of the spring member 113 abuts against the second valve seat 110 and the other end abuts against the piston 112 of the piston portion 103 to apply a force to the piston 112 downward. An air inlet hole 114 is formed in the upper portion of the first valve seat 109, and the air inlet hole 114 is communicated with the portion, below the piston 112, in the power cavity 111. The upper end of the striker 108 of the piston portion 103 is received in the power chamber 111 and fixed to the piston 112. The striker 108 extends linearly from the top down and enters the housing chamber 104 from the power chamber 111, and a lower portion (distal end) of the striker 108 extends to the glue dispensing head 102 mounted on a lower portion of the first valve seat 109.

Without venting to power chamber 111 via air intake hole 114, spring member 113 pushes piston portion 103 downward to abut the lower portion of striker 108 against glue head 102, thereby closing glue outlet valve 100. With the vent to power chamber 111 via air inlet hole 114, piston 112 is pushed upward and striker 108 disengages glue dispensing head 102, thereby opening glue dispensing valve 100.

The lower part of the first valve seat 109 is provided with a glue inlet hole 121, and the glue inlet hole 121 is communicated with the accommodating cavity 104. Specifically, after being injected from the glue inlet hole 121, the glue is stored in the accommodating cavity 104 and is discharged through the glue outlet head 102. The type of glue outlet valve 100 is determined according to the way the glue is discharged, and may be, for example, a glue dispensing valve, a glue spraying valve, a glue applying valve, etc.

The glue discharging head 102 is detachably attached to the valve body 101 by, for example, a screw in the direction in which the striker 108 is driven (up-down direction). Thus, the glue dispensing head 102 can be detached, and therefore maintenance thereof can be facilitated. In addition, since the glue dispensing head 102, the second valve seat 110 and the first valve seat 109 are designed separately, the difficulty in processing each component can be reduced.

As described above, the adjustment portion 200 adjusts the striker 108 or the glue-dispensing head 102 in the axial direction to adjust the distance between the distal end of the striker 108 and the glue-dispensing head 102 in a state where the distal end of the striker 108 is away from the position of the glue-dispensing head 102. Specifically, the adjusting portion 200 may be disposed on the valve body 101, and more specifically, the adjusting portion 200 is disposed on the opposite side of the valve body 101 from the side where the glue head 102 is mounted. For example, the regulating portion 200 is provided at an upper portion of the valve body 101. In order to accurately adjust the position of the striker 108, the adjustment portion 200 may include an adjustment screw 201, and the adjustment screw 201 is mounted to an opposite side (i.e., an upper side) of the valve body 101 from a side where the dispensing head 102 is mounted and abuts the striker 108. The adjustment screw 201 is adjustable in the direction in which the striker 108 is driven (up-down direction in the drawing). By providing the adjustment screw 201, the feed stroke thereof in the up-down direction can be finely adjusted, and thereby the distance between the distal end of the striker 108 and the glue dispensing head 102 in a state where the distal end of the striker 108 is away from the position of the glue dispensing head 102 can be adjusted.

For more convenient adjustment, for example, one end of adjusting screw 201 extends into cavity 107 and abuts striker 108 in cavity 107; the other end of the adjusting screw 201 is exposed to the outside of the valve body 101. By exposing the other end of the adjusting screw 201 to the outside of the valve body 101, the operator can easily operate the other end of the adjusting screw 201 to select the adjusting screw 201.

In order to simplify the adjustment structure of the adjustment part 200, the adjustment part 200 may further include an internal thread part 202 provided on the opposite side of the valve body 101 from the side where the rubber head 102 is mounted, and an external thread part 203 of the adjustment screw 201 is screwed to the internal thread part 202. For example, a threaded hole (no reference numeral) is opened in the upper portion of the valve body 101, and the internal thread of the threaded hole is used as the internal thread portion 202 of the adjustment portion 200. The thread of the internal thread portion 202 may be a fine thread, for example. The threaded bore is coaxial with the power cavity 111. In addition, in order to facilitate selection of the adjustment screw 201, a handle portion 204 is provided at one end of the adjustment screw 201 exposed to the outside of the valve body 101. The handle portion 204 is provided, for example, on the upper portion of the male screw portion 203 of the adjustment screw 201.

Further, valve body 101 is provided with a connection hole 115 between the screw hole and power chamber 111, and connection hole 115 is used to communicate the outside of valve body 101 with power chamber 111 (chamber 107) inside valve body 101. A cylindrical portion 206 is provided at one end of the adjustment screw 201 that abuts the striker 108. The outer periphery of the cylindrical portion 206 is smooth. The cylindrical portion 206 is located below the male screw portion 203 of the adjustment screw 201. In a state where the external thread portion 203 of the adjustment screw 201 is screwed with the internal thread portion 202, the cylindrical portion 206 of the adjustment screw 201 passes through the connection hole 115 to be inserted into the power chamber 111 from the outside of the valve body 101. A seal 207 is provided between the connection hole 115 and the cylindrical portion 206 for sealing the power chamber 111. Specifically, the sealing member 207 may be, for example, a packing, and the packing is fitted into the coupling hole 115. In the state of being inserted into the power chamber 111, the upper end portion of the striker 108 abuts against the lower end portion of the cylindrical portion 206 of the adjusting screw 201.

Thus, without venting to power chamber 111 via air intake hole 114, spring member 113 pushes piston portion 103 downward to cause the lower portion of striker 108 to abut glue dispensing head 102, thereby closing glue dispensing valve 100. With the vent to power chamber 111 via air inlet hole 114, piston 112 is pushed upward and striker 108 disengages glue dispensing head 102, thereby opening glue dispensing valve 100. In this case, the upper end portion of the striker 108 abuts against the lower end portion of the cylindrical portion 206 of the adjusting screw 201, and when the cylindrical portion 206 is adjusted downward, the position (also referred to as the first position for convenience of explanation) where the upper end portion of the striker 108 is regulated by the lower end portion of the cylindrical portion 206 is also moved downward, and the distance from the distal end (lower end) of the striker 108 to the position (also referred to as the second position for convenience of explanation) where the striker abuts against the rubber head 102 is shortened, whereby the distance between the first position and the second position is shortened, the time required for switching the striker 108 between the first position and the second position is shortened, that is, the switching frequency of the striker 108 is increased. Conversely, when the cylindrical portion 206 is adjusted upward, the switching frequency of the striker 108 becomes slower.

This enables adjustment of the switching frequency of the striker 108. When a plurality of glue valves 100 are used simultaneously, all the glue valves 100 can be switched at the same frequency or slightly shifted from each other as needed by finely adjusting the adjustment units 200 of the glue valves 100.

Although the example in which the adjustment portion 200 is provided in the valve body 101 and the first position of the striker 108 is adjusted by the adjustment screw 201 has been described above, the switching frequency of the striker 108 is adjusted, but the present invention is not limited thereto.

Referring to fig. 3, for example, in the case where the dispensing head 102 is detachably mounted on the lower portion of the valve body 101, the regulating portion 200 may also be provided between the valve body 101 and the dispensing head 102. Specifically, for example, the regulating portion 200 may include a regulating washer 208, and the regulating washer 208 is sandwiched between the valve body 101 and the dispensing head 102. Thus, the second position can be adjusted by adjusting the position of the glue dispensing head 102. Thereby, the distance between the first position and the second position can also be changed.

While embodiments of the present embodiments have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the embodiments, the scope of which is defined by the claims and their equivalents.
