[0050] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0051] Reference to "embodiment" herein means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0052] Refer to Figures 1 to 5, an embodiment of the present utility model provides a dispensing needle output control device, comprising: a valve body needle 10, a valve core 20 and a valve core control device 30. The valve body needle 10 includes a valve body, an adhesive outlet tube 102 is provided at the adhesive outlet end of the valve body, and an adhesive inlet 101 is provided at the adhesive inlet end of the valve body. A fluid passage 105 is provided between the adhesive inlet 101 and the adhesive outlet tube 102. A valve core groove 104 is provided at the side end of the valve body, the valve core 20 is arranged in the valve core groove 104, and an adhesive outlet through hole 2011 is provided on the valve core 20. The valve core control device 30 is connected to the valve core 20, and the valve core control device 30 is used to drive the valve core 20 to rotate to control the communication or non-communication between the adhesive outlet through hole 2011 and the fluid passage 105, so as to control the dispensing conduction or non-conduction of the fluid passage 105.

[0053] As Figure 5 shown in, since the valve core 20 is arranged in the valve body, and an adhesive outlet through hole 2011 is provided on the valve core 20. Thus, during dispensing, after the glue is introduced from the adhesive inlet 101 of the valve body, it can flow into the adhesive outlet through hole 2011 through the fluid passage 105, and then be output from the other end of the adhesive outlet through hole 2011, and continue to flow into the adhesive inlet end of the adhesive outlet tube 102 through the fluid passage 105, and the glue is led out externally through the adhesive outlet tube 102. When it is necessary to stop dispensing, the valve core control device 30 can be used to drive the valve core 20 to rotate, so that the adhesive outlet through hole 2011 is not communicated with the fluid passage 105, and the continuous outflow of the glue can be blocked, realizing the on-off control of the glue output during dispensing.

[0054] Referring to Figure 2 and Figure 5 , a needle tube installation passage 103 is further provided at the adhesive outlet end of the valve body close to the adhesive outlet end. The needle tube installation passage 103 is communicated with the fluid passage 105, and the adhesive outlet tube 102 is installed in the needle tube installation passage 103 to lead out the glue in the fluid passage 105 externally. As Figure 5 shown in, through the needle tube installation passage 103, the adhesive outlet tube 102 can be directly installed in the valve body and directly communicated with the fluid passage 105. So that the needle tube and the valve body form an integral structural member. Compared with the split structure, the cooperation between the needle tube and the valve body is better, and the glue output is more stable.

[0055] Referring to Figure 3 and Figure 5 , the valve core 20 includes: a valve stem 201 and a valve core joint 202. The adhesive outlet through hole 2011 is provided on the valve stem 201. The valve stem 201 is fixedly connected to the valve core joint 202, and the valve stem 201 is installed in the valve core groove 104. As Figure 3 andFigure 5 As shown, the size of the valve stem 201 is adapted to the size of the valve core groove 104, and the size of the connection between the glue outlet through-hole 2011 and the fluid passage 105 is adapted, so as to prevent the glue from permeating outwards. The valve stem 201 is located inside the valve body, while the valve core joint 202 is located outside the valve body, thus facilitating the rotation of the valve core joint 202 driven by the valve core control device 30.

[0056] Refer to Figure 3 and Figure 4 , the valve core control device 30 includes: a mounting plate 301, a connecting plate 302 and a driving cylinder 303. The valve body needle 10 is mounted on the mounting plate 301; the connecting plate 302 is fixedly connected to the mounting plate 301; the driving cylinder 303 is mounted on the connecting plate 302. A cylinder connection head is provided on the driving cylinder 303, and the cylinder connection head is connected to the valve core joint 202 to drive the valve core 20 to rotate through the valve core joint 202. As Figure 3 and Figure 4 shown, a cylinder mounting position 3021 is further provided on the connecting plate 302, and the driving cylinder is mounted on the cylinder mounting position 3021. Among them, cylinder head through-holes 3022 are respectively provided on the mounting plate 301 and the connecting plate 302, and the cylinder connection head passes through the cylinder head through-hole 3022 to be connected to the valve core joint 202. In this way, the valve core joint 202 can be driven to rotate. Among them, a valve body mounting position 3012 is further provided on the mounting plate 301, and the valve body needle 10 is mounted on the valve body mounting position 3012, so that the valve body needle 10 can be fixedly mounted relative to the mounting plate 301.

[0057] Refer to Figure 3 and Figure 4 , flat surfaces are respectively provided on both sides of the valve core joint 202. The cylinder connection head is a Y-shaped connection head, and the valve core joint 202 is arranged in the groove of the Y-shaped connection head. The flat surfaces on both sides of the valve core joint 202 are in contact with the inner wall of the groove of the Y-shaped connection head to rotate under the drive of the inner wall. As Figure 3 and Figure 4 shown, flat surfaces are provided on both sides of the valve core joint 202, so that it can be better connected to the Y-shaped connection head, and under the action of the driving cylinder 303, the valve core joint 202 can be better driven to rotate.

[0058] Refer to Figures 3 to 5, the dispensing needle output control device further includes: a needle mounting housing 40.
