Referring to fig. 1 to 4, and mainly to fig. 1, 2 and 3, a glue outlet valve 100 according to embodiment 1 includes: the glue dispensing valve comprises a valve body 101, a glue dispensing head 102 and a piston part 103 which moves back and forth relative to the valve body 101 to open or close the glue dispensing valve 100. The valve body 101 is provided with a receiving cavity 104 for receiving glue. The glue outlet head 102 is provided with a through glue outlet channel 105, and the glue outlet channel 105 is communicated with a glue outlet hole 106 and an accommodating cavity 104 of the glue outlet head 102 in the state that the glue outlet head 102 is installed on the valve body 101. The glue outlet passage 105 is provided with a first inclined portion 107 having a gradually decreasing cross section in a direction from the housing chamber 104 to the glue outlet hole 106 (vertical direction in the drawing) on a side close to the glue outlet hole 106. The piston portion 103 has a striker 108, and a part of the striker 108 is housed in the valve body 101. The distal end of striker 108 extends into glue outlet channel 105 of glue outlet head 102. The striker 108 can be driven to reciprocate and abut against the first inclined portion 107 or disengage from the first inclined portion 107 to close the glue outlet 106 or open the glue outlet 106.
According to the glue outlet valve 100 of the present embodiment, the amount of glue remaining can be reduced. Specifically, since the first inclined portion 107 is provided on the side of the glue outlet passage 105 close to the glue outlet hole 106, that is, the glue outlet valve 100 is blocked at a position closer to the glue outlet hole 106, it is possible to reduce the amount of glue remaining at a position in the glue outlet hole 106 that is not blocked.
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 below. The upper portion of the first valve seat 109 forms a power chamber 111. The first valve seat 109 and the second valve seat 110 together form a receiving chamber 104 in the lower part of the valve body 101. The piston 112 of the piston portion 103 is accommodated in the power chamber 111, and further, a spring member 113 is accommodated in the power chamber 111, and one end of the spring member 113 abuts against the first valve seat 109 and the other end abuts against the piston 112 of the piston portion 103, and urges 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 second valve seat 110.
Without venting the power chamber 111 through the air intake hole 114, the spring member 113 pushes the piston portion 103 downward to bring the lower portion of the striker 108 into abutment with the first inclined portion 107, thereby closing the glue outlet valve 100. With the ventilation toward power chamber 111 via intake hole 114, piston 112 is pushed upward, striker 108 disengages from first inclined portion 107, and glue valve 100 is opened.
The first valve seat 109 is formed with a first cavity 115 in a lower portion thereof, and the second valve seat 110 is formed with a second cavity 116. In a state where the second valve seat 110 is mounted to the first valve seat 109, the first cavity 115 and the second cavity 116 together form the accommodation chamber 104. The power chamber 111, the first chamber 115, and the second chamber 116 are coaxial in the vertical direction, and thereby the entire piston portion 103 can be smoothly reciprocated relative to the valve body 101.
With continued reference to fig. 4 and with additional reference to fig. 2, to further improve the precision of the reciprocating movement of the striker 108 of the piston portion 103 and to reduce the swing amplitude of the striker 108 during the reciprocating movement, the glue dispensing valve 100 may further include a guide sleeve 117 for guiding the striker 108. The guiding sleeve 117 can be embedded in the accommodating cavity 104, and a glue accommodating space 118 is formed between the guiding sleeve 117 and the inner wall of the accommodating cavity 104. For example, the guiding sleeve 117 may be embedded in the second valve seat 110, the outer periphery of the guiding sleeve 117 may be in the shape of a substantially equilateral triangle, and the guiding sleeve 117 is precisely (e.g., transition fit or interference fit) fitted with the second cavity 116 of the second valve seat 110 forming the receiving cavity 104 through the positions of the three corners. Furthermore, between the outer circumference of the guiding sleeve 117 and the inner wall of the second cavity 116, a glue receiving space 118 is formed, which can receive glue and allow glue to pass through. Thus, by providing the guide sleeve 117 for guiding the striker 108, the swing width of the striker 108 during the reciprocating movement can be reduced.
For ease of maintenance, in some embodiments, the glue valve 100 may further include a mounting nut 119, the mounting nut 119 removably mounting the glue head 102 to the valve body 101. For example, the mounting nut 119 may be screwed with the second valve seat 110, the glue outlet head 102 is hung in the mounting cavity 120 of the mounting nut 119, and the glue outlet head 102 is tightly attached to the second valve seat 110 in a manner that the glue outlet channel 105 of the glue outlet head 102 and the second cavity 116 of the second valve seat 110 are coaxial and face upward. Therefore, the glue dispensing head 102 can be detached, and therefore maintenance of the glue dispensing head can be facilitated. In addition, since the glue dispensing head 102, the second valve seat 110 and the first valve seat 109 are designed to be separated, the difficulty in processing each component can be reduced.
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, the glue inlet hole 121 penetrates to the first cavity 115. After being injected from the glue inlet hole 121, the glue is discharged through the first cavity 115, the second cavity 116, the glue outlet channel 105 of the glue outlet head 102, and the glue outlet hole 106. 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.
With continued reference to fig. 3, as described above, the glue outlet passage 105 is provided with the first inclined portion 107 having a gradually decreasing cross section in a direction from the housing chamber 104 to the glue outlet hole 106 (in the up-down direction in the drawing) on a side close to the glue outlet hole 106. That is, the cross section of the first inclined portion 107 is formed to be gradually smaller from top to bottom, whereby the flow speed of the glue can be made faster at a position closer to the glue outlet 106. In addition, the quality of plugging of the glue head 102 can be improved.
In addition, in order to further increase the flowing speed of the glue, the diameter of the glue outlet 106 can be made smaller than the diameter of the position with the smallest cross section in the first inclined part 107. For example, the diameter of the glue outlet 106 may be made smaller than the diameter of the lowermost portion of the first inclined portion 107. This can further increase the flow rate of the glue at the position of the glue outlet 106. In addition, by reducing the diameter of the glue outlet 106, the amount of glue that can remain in the glue outlet 106 can be further reduced.
In some embodiments, to more reliably close the glue dispensing head 102, the distal end of the striker 108 is provided with a second inclined portion 122 having a gradually decreasing cross-section in a direction from the accommodating chamber 104 to the glue dispensing hole 106. When the striker 108 is driven toward the glue outlet 106, the second inclined portion 122 may abut against a side (i.e., a lower side) of the first inclined portion 107 opposite to the glue outlet 106. Specifically, the second inclined portion 122 is provided at a lower portion of the striker 108, and a diameter of a cross section of a position of a lower end of the second inclined portion 122 is smaller than a diameter of a cross section of a position of a lower end of the first inclined portion 107, and a diameter of a cross section of a position of an upper end of the second inclined portion 122 is larger than a diameter of a cross section of a position of a lower end of the first inclined portion 107. Thus, when the striker 108 is driven toward the glue outlet 106, the second inclined portion 122 abuts the first inclined portion 107 at a position in the middle in the vertical direction in a line contact manner.
By bringing the second inclined part 122 into line contact with the first inclined part 107, the area of contact between the first inclined part 107 and the second inclined part 122 can be reduced, and even if there is an error in processing the first inclined part 107 or the second inclined part 122, the glue dispensing head 102 can be reliably closed, thereby preventing leakage of glue.
In addition, in order to further reduce the amount of residual glue at the glue outlet 102, a portion of the distal end of the striker 108 protrudes into the glue outlet 106. For example, the first inclined portion 107 and the glue outlet 106 may be directly connected, and the second inclined portion 122 may extend to the end of the distal end of the striker 108. When the second inclined portion 122 and the first inclined portion 107 are in line contact with each other, a lower portion of the second inclined portion 122 passes through the first inclined portion 107 and protrudes into the glue outlet 106. Therefore, when the striker 108 closes the glue outlet valve 100, the part of the distal end of the striker 108 protruding into the glue outlet hole 106 simultaneously pushes out the glue remaining in the glue outlet hole 106, thereby further reducing the residual glue amount of the glue outlet head 102. When the striker 108 abuts against the first inclined portion 107, the distance S1 between the end of the distal end of the striker 108 and the end of the glue outlet 106 may be, for example, 0mm or more and 0.5mm or less. That is, by setting the distance S1 between the distal end of the striker 108 and the end of the glue outlet 106 to 0mm or more, the lower portion of the first inclined portion 107 does not protrude out of the glue outlet 102 when the striker 108 abuts the first inclined portion 107, and the striker 108 can be prevented from being knocked. Further, by setting the distance S1 between the distal end of the striker 108 and the end of the glue outlet 106 to 0.5mm or less, the amount of glue that can remain in the glue outlet 106 in the closed state can be further reduced.
In some embodiments, in order to close the glue dispensing head 102 more reliably, the distal end of the striker 108 is provided with a third inclined portion 123 having a gradually decreasing cross section in the direction from the accommodating chamber 104 to the glue dispensing hole 106. The third inclined portion 123 is opposite to the second inclined portion 122 and opposite to the accommodating chamber 104. When the striker 108 is driven toward the glue outlet 106, the third inclined portion 123 may abut against a side of the first inclined portion 107 opposite to the accommodating chamber 104. Specifically, the third inclined part 123 is disposed above the second inclined part 122, and a lower portion of the third inclined part 123 is connected to an upper portion of the second inclined part 122. The diameter of the cross section at the position of the lower end of the third slope part 123 is smaller than the diameter of the cross section at the position of the upper end of the first slope part 107. Thus, when the striker 108 is driven toward the glue outlet 106, the third inclined portion 123 can abut against the upper end of the first inclined portion 107. The third inclined portion 123 abuts the upper end of the first inclined portion 107 in a line contact manner at a position in the middle in the up-down direction.
Thus, when the distal end of the striker 108 abuts against the first inclined portion 107, the second inclined portion 122 and the third inclined portion 123 of the striker 108 abut against the first inclined portion 107 in a line contact manner. That is, by providing the second inclined part 122 and the third inclined part 123 having different inclination angles, the second inclined part 122 and the lower end of the first inclined part 107 are brought into line contact with each other, and the third inclined part 123 and the upper end of the first inclined part 107 are brought into line contact with each other, so that the dispensing head 102 can be closed by closing the dispensing head 102 at two positions of the first inclined part 107, and the dispensing head 102 can be more reliably closed. Further, since the inclination angles of the second and third inclined parts 122 and 123 are different, the second and third inclined parts 122 and 123 can be brought into line contact with the first inclined part 107, respectively, thereby further improving the reliability of the contact between the second and third inclined parts 122 and 123 and the first inclined part 107.
The glue dispensing valve 100 according to the above embodiment can be used in various glue dispensing apparatuses (not shown). The type of the glue dispensing equipment is not particularly limited, and examples thereof include a dispenser, a doctor blade, a glue sprayer, and a glue applicator.
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.
