[0020] Embodiment 1 like Figure 1 - Figure 2 As shown, a two-component feeding device includes a mixing pretreatment chamber 2, the top of the mixing pretreatment chamber 2 is connected to a feeding pipe 1, the bottom of the mixing pretreatment chamber 2 is connected to an extrusion joint 3, and the interiors of the mixing pretreatment chamber 2 and the feeding pipe 1 are both embedded with a homogenizing mechanism 4, the homogenizing mechanism 4 is in contact with the inner wall of the feeding pipe 1 or the mixing pretreatment chamber 2, and the interior of the homogenizing mechanism 4 is provided with a plurality of groups of uniform distribution units 5 for uniformly distributing materials, and the uniform distribution units 5 are provided with a plurality of groups evenly distributed inside the homogenizing mechanism 4.

[0021] Furthermore, the mixing pretreatment chamber 2 is provided with a plurality of groups, which are evenly distributed on the upper end surface of the mixing pretreatment chamber 2 .

[0022] When in use, the raw materials of the dispensing material are injected into the interior of the mixing pretreatment chamber 2 through the feeding pipe 1. The raw materials are mixed inside the mixing pretreatment chamber 2 to form a glue liquid, and the glue liquid is extruded to the adhesion position through the extrusion joint 3. A homogenizing mechanism 4 is provided inside the mixing pretreatment chamber 2 and the feeding pipe 1. The homogenizing mechanism 4 is laid inside the feeding pipe 1 and the mixing pretreatment chamber 2 and fits with the inner wall thereof. The raw materials and the mixed glue liquid are squeezed and passed through the uniform distribution unit 5 inside the homogenizing mechanism 4 under the action of the internal pressure of the feeding pipe 1. The uniform distribution unit 5 is uniformly distributed inside the homogenizing mechanism 4, so that the raw materials and the mixed glue liquid are uniformly distributed, thereby improving the dispersion of the raw materials inside the feeding pipe 1 and also improving the mixing effect of the glue liquid inside the mixing pretreatment chamber 2.

[0023] Embodiment 2 Based on the first embodiment, Figure 1-4 As shown, the uniform distribution unit 5 includes a conducting cavity 6 and a uniform distribution block 8. The conducting cavity 6 is opened through the interior of the homogenizing mechanism 4. The uniform distribution block 8 is elastically embedded in the conducting cavity 6, and the uniform distribution block 8 is elastically fitted to the inner wall of the conducting cavity 6. The cross-sectional areas of the two end surfaces of the conducting cavity 6 are different, and the uniform distribution block 8 is in the shape of a cone.

[0024] When in use, a conducting cavity 6 is provided, and a uniformly distributed block 8 is provided inside the conducting cavity 6. At the same time, the cross-sectional areas at both ends of the conducting cavity 6 are different, so that the material or the mixed glue liquid can push open the uniformly distributed block 8 through one end of the conducting cavity 6 with a larger area under the action of pressure and flow into the end of the conducting cavity 6 with a larger area. Since the areas at both ends of the conducting cavity 6 are different, the liquid pressures at both ends of the conducting cavity 6 are different. At the same time, when the liquid passes through the conducting cavity 6, the uniformly distributed block 8 can also evenly distribute the material or the mixed glue liquid, thereby improving the dispersion of the material and the mixing effect of the glue liquid. The uniformly distributed block 8 is a frustum structure with a large bottom area, which can also effectively prevent the glue liquid in the mixing pretreatment cavity 2 from flowing back into the interior of the feed pipe 1 and causing pollution.

[0025] like Figure 1 - Figure 5 As shown, the evenly distributed block 8 is elastically fitted with the conducting cavity 6 via an elastic telescopic rod 11 , and a rotating ring 7 is provided at one end of the elastic telescopic rod 11 which is away from the end of the evenly distributed block 8 .

[0026] like Figure 1 - Figure 5 As shown, the elastic telescopic rod 11 includes a telescopic sleeve 13 and a telescopic rod 14. The telescopic rod 14 is fixedly connected to the rotating ring 7. The telescopic rod 14 is elastically embedded in the elastic telescopic rod 11, and the end of the telescopic sleeve 13 away from the elastic telescopic rod 11 is connected to the inclined portion of the uniformly distributed block 8.

[0027] Furthermore, multiple groups of elastic telescopic rods 11 are provided, which are evenly and symmetrically arranged on the inclined surface of the uniformly distributed block 8 along the center of the uniformly distributed block 8, and a groove adapted to the rotating ring 7 and the telescopic rods 14 is provided inside the homogenizing mechanism 4.

[0028] When in use, when the uniform distribution block 8 moves inside the conducting cavity 6 under the action of material pressure to form a guide gap, the material is evenly distributed through the guide gap between the conducting cavity 6 and the uniform distribution block 8, and in the process of material flow, the elastic telescopic rod 11 is arranged on the inclined portion of the uniform distribution block 8, so that the elastic telescopic rod 11 will penetrate the guide gap between the conducting cavity 6 and the uniform distribution block 8, so that the elastic telescopic rod 11 can further disperse the material flowing inside the guide gap, thereby further improving the dispersion and uniform distribution effect of the material.

[0029] like Figure 1 - Fig.10 As shown, the inclined portion of the uniformly distributed block 8 is embedded with multiple groups of guide plates 12, which are spirally distributed on the inclined portion of the uniformly distributed block 8. A rotating rod 10 is fixedly connected to the bottom center of the uniformly distributed block 8, and multiple groups of stirring rods 9 are fixedly connected to the side end surface of the rotating rod 10.

[0030] When in use, through the spirally distributed guide plate 12, when the material flows along the surface of the uniform distribution block 8, the fluid pressure will drive the uniform distribution block 8 to rotate through the guide plate 12, and the rotation of the uniform distribution block 8 will drive the rotating rod 10 and the stirring rod 9 at the bottom to rotate synchronously, thereby further improving the mixing and uniform distribution effect of the material and the glue.

[0031] like Figure 1 - Fig.10 As shown, the guide plate 12 is fixedly connected to the bottom of the telescopic rod 14 , the telescopic sleeve 13 is provided with a movable groove 15 adapted to the guide plate 12 , and a guide cavity 17 is formed between the guide plate 12 and the inner wall of the conducting cavity 6 .

[0032] When in use, the guide plate 12 is fixedly connected to the telescopic rod 14 so that the guide plate 12 remains in contact with the inner wall of the conducting cavity 6 while the uniform distribution block 8 moves, and a guide cavity 17 is formed between the conducting cavity 6 and the uniform distribution block 8. The guide cavity 17 can further improve the rotational driving effect of the uniform distribution block 8, and the rotation of the uniform distribution block 8 will also further improve the uniform distribution and dispersion effect of the uniform distribution block 8 and the rotating rod 10 on the material.

[0033] A glue dispensing machine is also provided, comprising the above-mentioned two-component feeding device.

[0034] Working principle: The raw materials of the dispensing materials are injected into the mixing pretreatment chamber 2 through the feeding pipe 1. The raw materials are mixed in the mixing pretreatment chamber 2 to form glue liquid. The glue liquid is extruded to the adhesion position through the extrusion joint 3. A homogenizing mechanism 4 is provided inside the mixing pretreatment chamber 2 and the feeding pipe 1. The homogenizing mechanism 4 is laid inside the feeding pipe 1 and the mixing pretreatment chamber 2 and fits with the inner wall thereof. The raw materials and the mixed glue liquid are squeezed and passed through the uniform distribution unit 5 inside the homogenizing mechanism 4 under the action of the internal pressure of the feeding pipe 1. The uniform distribution unit 5 is uniformly distributed inside the homogenizing mechanism 4, thereby uniformly distributing the raw materials and the mixed glue liquid, thereby improving the dispersion of the raw materials inside the feeding pipe 1 and also The mixing effect of the glue liquid inside the mixing pretreatment chamber 2 can be improved. By providing a conducting chamber 6, a uniform block 8 is provided inside the conducting chamber 6, and the cross-sectional areas of the two ends of the conducting chamber 6 are different, so that the material or the mixed glue liquid can pass through the end with the larger area of ​​the conducting chamber 6 under the action of pressure, push the uniform block 8 and flow into the end with the larger area of ​​the conducting chamber 6. Since the two ends of the conducting chamber 6 have different areas, the liquid pressures at the two ends of the conducting chamber 6 are different. At the same time, when the liquid passes through the conducting chamber 6, the uniform block 8 can also evenly divide the material or the mixed glue liquid, thereby improving the dispersion of the material and the mixing effect of the glue liquid. The uniform block 8 is a frustum structure with a larger bottom area, which can also effectively avoid the mixing pretreatment. The glue inside the cavity 2 flows back into the inside of the feed pipe 1 and causes pollution. When the uniform distribution block 8 moves inside the conduction cavity 6 under the action of the material pressure to form a guide gap, the material is evenly distributed through the guide gap between the conduction cavity 6 and the uniform distribution block 8. In the process of material flow, the elastic telescopic rod 11 is arranged on the inclined portion of the uniform distribution block 8, so that the elastic telescopic rod 11 will penetrate the guide gap between the conduction cavity 6 and the uniform distribution block 8, so that the elastic telescopic rod 11 can further disperse the material flowing inside the guide gap, thereby further improving the dispersion and uniform distribution effect of the material. By providing a spirally distributed guide plate 12, when the material moves along the uniform distribution block 8 flows on the surface, the fluid pressure will drive the uniform distribution block 8 to rotate through the guide plate 12, and the rotation of the uniform distribution block 8 will drive the rotating rod 10 and the stirring rod 9 at the bottom to rotate synchronously, thereby further improving the mixing and uniform distribution effect of the material and the glue. The guide plate 12 is fixedly connected to the telescopic rod 14, so that the uniform distribution block 8 keeps in contact with the inner wall of the conduction cavity 6 while the uniform distribution block 8 moves, and a guide cavity 17 is formed between the conduction cavity 6 and the uniform distribution block 8. The guide cavity 17 can further improve the rotation driving effect of the uniform distribution block 8, and the rotation of the uniform distribution block 8 will also further improve the uniform distribution and dispersion effect of the uniform distribution block 8 and the rotating rod 10 on the material.
