[0030] Specifically, the first glue cylinder 16 and the second glue cylinder 17 are used to contain two components of glue respectively, and the mixing valve is arranged between the first glue cylinder 16 and the second glue cylinder 17. The upper and lower ends of the mixing cylinder 2 are provided with two glue inlets, and the two glue inlets are respectively connected with the glue outlets of the first glue cylinder 16 and the second glue cylinder 17. The control component 18 is mainly composed of two dispensing valves, which can be pneumatic dispensing valves or screw dispensing valves. The two dispensing valves are operated simultaneously to control the glue in the first glue cylinder 16 and the second glue cylinder 17 to be simultaneously fed into the mixing cylinder 2 at a ratio of 1:1 for mixing.

[0031] Reference Figure 2 and Figure 3In the embodiment of the present application, the mixing barrel 2 is composed of a first barrel 21 located at the upper end and a second barrel 22 located at the lower end, wherein the cross section of the first barrel 21 located at the upper end is circular, and the cross section of the second barrel 22 located at the lower end is annular, and a mounting cavity is formed inside the second barrel 22, and the upper end of the glue discharge barrel 3 is coaxially arranged in the mounting cavity, and the upper surface of the glue discharge barrel 3 is fixed to the lower surface of the first barrel 21; the two glue outlets of the mixing barrel 2 are respectively opened on two sides of the lower end of the second barrel 22 that are away from each other, the glue outlet of the mixing barrel 2 is opened at the bottom of the first barrel 21, and the glue outlet of the glue discharge barrel 3 is opened at the top center position, and is opened opposite to the glue outlet of the mixing barrel 2. The two-component glue enters the mixing barrel 2 from the first barrel 21 and the second barrel 22, and can be sent into the glue discharge barrel 3 after being fully mixed, and is sent out from the glue discharge barrel 3 to dispense glue on the workpiece.

[0032] Reference Figure 3 and Figure 4 In the embodiment of the present application, the screw valve 5 includes a power piece 51, a central shaft 52 and a screw body 53, wherein the power piece 51 is preferably a motor, the output shaft of the motor is vertically arranged and connected to the central shaft 52, the lower end of the central shaft 52 passes through the top plate of the first cylinder 21 and is inserted into the first cylinder 21, and the central shaft 52 is connected to the first cylinder 21 for relative rotation through a sealing bearing or the like; the screw body 53 mainly includes a column body and spiral leaves spirally wound on the column body, the upper end of the screw body 53 is connected to the central shaft 52, and the lower end extends into the glue discharge barrel 3, and the spiral leaves on the screw body 53 are in contact with the inner wall of the glue discharge barrel 3. When the motor drives the screw body 53 to rotate, the spiral leaves on the screw body 53 can continuously push the glue in the upper first cylinder 21 downward to the glue discharge end during the rotation process.

[0033] Reference Figure 3 and Figure 4 In the embodiment of the present application, the stirring assembly 4 includes a connecting rod 41 and a stirring rod 42. One end of the connecting rod 41 is fixed to the side wall of the central shaft 52, and the connecting rod 41 is preferably arranged vertically with the central shaft 52. The other ends are connected to the stirring rod 42, and the lower end of the stirring rod 42 extends downward into the second cylinder 22. When the central shaft 52 rotates, the connecting rod 41 is driven to rotate, and the stirring rod 42 is driven by the connecting rod 41 to rotate circumferentially in the second cylinder 22, so that the glue entering the mixing cylinder 2 from the lower glue inlet is stirred and mixed; as the glue inlet continues to be fed, the mixed glue moves upward under the push of the new glue entering from the lower end, and is sent into the glue outlet 3 from the upper glue outlet, so that the two components of glue can be fully mixed to improve the dispensing effect.

[0034] Reference Figure 3 and Figure 4In the embodiment of the present application, the stirring assembly 4 also includes a gear 43 and a rack 44. Specifically, the upper end of the stirring rod 42 is rotatably arranged on the connecting rod 41, the gear 43 is coaxially sleeved on the outer wall of the stirring rod 42, and the rack 44 is circumferentially fixed on the inner wall of the first cylinder 21, and the gear 43 is meshed with the rack 44. When the connecting rod 41 rotates with the central axis 52, the stirring rod 42 rotates circumferentially corresponding to the inner circumference of the second cylinder 22, and the two kinds of glue are driven to mix with each other; with the cooperation of the gear 43 and the rack 44, the stirring rod 42 can also rotate along its own center line at the same time, further stirring and mixing the local glue, and improving the mixing effect. Preferably, a plurality of connecting rods 41 are circumferentially fixed on the central axis 52, and each connecting rod 41 is provided with a stirring rod 42 and a gear 43 in a one-to-one correspondence, and all gears 43 are meshed with the rack 44.

[0035] Preferably, in order to improve the stirring and mixing effect, the lower end of the stirring rod 42 may be wavy, or may be fixed with a plurality of spirally rotating stirring sleeves, so that when the stirring rod 42 rotates along its own center, the local stirring effect can be improved.

[0036] Reference Figure 4 and Figure 5 In an optional embodiment, a dosing ring 6 is fixed at the bottom of the second cylinder 22, and the dosing ring 6 is annular; two glue inlets are symmetrically provided on the outer wall of the dosing ring 6, and the glue inlet of the dosing ring 6 is aligned with the glue inlet of the mixing cylinder 2 and is connected to each other; two dosing grooves 61 are also provided on the dosing ring 6, and the two dosing grooves 61 are respectively arranged at the middle position of the two glue inlets on the dosing ring 6. From the horizontal plane, the two glue inlets and the two dosing grooves 61 are respectively located at four points that divide the dosing ring 6 into four equal parts, and the dosing grooves 61 are connected with the two glue inlets on the dosing ring 6, and the glue entering the dosing ring 6 from the first glue cartridge 16 and the second glue cartridge 17 flows to the dosing grooves 61 The distance traveled by the distance traveled by the dosing grooves 61 is the same; at the same time, the dosing grooves 61 extend upward to the upper surface of the dosing ring 6 to form a glue outlet.

[0037] In this design, the dosing ring 6 functions like a dosing device, which premixes the glue from the first glue cylinder 16 and the second glue cylinder 17 at a ratio of nearly 1:1, and then feeds the two glues with a relatively uniform ratio into the mixing cylinder 2 for secondary mixing. This design makes it easier for the premixed glue to be in the mixing cylinder 2, and it is easier for the two glues to reach a uniform state.

[0038] Reference Figure 5Preferably, the dosing ring 6 is coaxially provided with a rotating shaft 62 in the dosing groove 61, and the rotating shaft 62 is a circular cylinder, and the lower end of the rotating shaft 62 is rotatably connected to the dosing ring 6; stirring blades 63 are fixed on the side wall of the rotating shaft 62 at intervals, and a plurality of stirring blades 63 are arranged circumferentially. Two first holes 64 are provided on the side wall of each dosing groove 61, and the two first holes 64 are respectively connected to the two glue inlets on the dosing ring 6, and the two first holes 64 are staggered on the horizontal projection plane. This design can make the two kinds of glue form a reasoning in one direction for the stirring blade 63 when entering the dosing groove 61, so that the stirring blade 63 drives the rotating shaft 62 to rotate, and the rotating stirring blade 63 can break up the two kinds of glue, thereby quickly forming an initial mixed state.

[0039] Furthermore, two groups of stirring blades 63 can be arranged along the length direction of the rotating shaft 62, and the two groups of stirring blades 63 are staggered and fixed. Such a design can further improve the stirring effect, because when the rotating shaft 62 rotates, the two groups of stirring blades 63 will work alternately, so that the glue is subjected to shear force multiple times in the mixing tank 61, thereby achieving a better mixing effect.

[0040] Reference Figure 4 and Figure 6 In an optional application embodiment, a bulk material ring 7 is fixed to the upper end of the batching ring 6 of the second cylinder 22. The bulk material ring 7 has two glue inlets on the lower surface, and the two glue inlets of the bulk material ring 7 are respectively connected to the two glue outlets on the batching ring 6. A plurality of second holes 71 are circumferentially spaced on the upper surface of the bulk material ring 7, and a connecting groove 72 is circumferentially formed inside the bulk material ring 7. The second holes 71 are connected to the glue inlet of the bulk material ring 7 through the connecting groove 72. The bulk material ring 7 can disperse the glue again before it enters the mixing cylinder 2, ensuring that the glue can be evenly distributed in the mixing cylinder 2 when entering the mixing cylinder 2, so that the glue can more evenly cover the entire cross section when entering the mixing cylinder 2.

[0041] Reference Figure 3 and Figure 4In an optional embodiment, a cooling cylinder 8 is provided between the glue discharging cylinder 3 and the second cylinder 22, and the inner and outer side walls of the cooling cylinder 8 are respectively in contact with the outer side wall of the glue discharging cylinder 3 and the inner side wall of the second cylinder 22; a cooling tube 81 is provided in the cooling cylinder 8, and the interior of the cooling cylinder 8 is hollow, and the cooling cylinder 8 can be preferably filled with condensate; the cooling tube 81 is arranged in a winding manner around the cooling cylinder 8, and the design of the cooling tube 81 can be serpentine or coil-shaped to increase the heat exchange area and improve the cooling efficiency; the two ends of the cooling tube 81 form an inlet pipe 82 and an outlet pipe 83 on the side wall of the cooling cylinder 8, and the external coolant can enter the cooling tube 81 from the inlet pipe 82 and finally be discharged from the outlet pipe 83. The main purpose of the cooling cylinder 8 is to control the temperature of the glue, to prevent the glue from solidifying during the mixing process in the mixing cylinder 2, and to affect the quality of the glue when it is retained in the glue discharging cylinder 3 for a short time. The coolant can be water or antifreeze, and the appropriate cooling medium can be selected according to the actual working conditions. Meanwhile, the cooling pipe 81 may also be designed in a cooling channel instead.

[0042] The implementation principle of a dispensing device in an embodiment of the present application is as follows: when dispensing glue to a workpiece, the two glues in the first glue cylinder 16 and the second glue cylinder 17 are simultaneously injected into the mixing cylinder 2. After entering the mixing cylinder 2, the two glues first pass through the dosing ring 6. After entering the dosing ring 6, the two glues flow along the channel in the dosing ring 6 in two parts, and converge in the dosing groove 61 to form a ratio of approximately 1:1, and are preliminarily mixed by the stirring blade 63 in the dosing groove 61 to form a mixed glue; then the mixed glue enters the bulk ring 7, passes through the connecting groove 72 in the bulk ring 7, and is sent into the inner cavity of the mixing cylinder 2 from the second hole 71 at the upper end; after being stirred by the stirring rod 42, the mixed glue gradually moves upward, and enters the glue outlet cylinder 3 from the glue outlet of the mixing cylinder 2, and is driven by the screw valve 5 to send out the glue outlet cylinder 3 to dispense glue to the workpiece.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
