[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Referring to Figure 1, a drip-proof device for a two-component dispensing machine includes a workbench 1. A pair of guide seats 2 are fixedly connected to the top of the workbench 1. A guide groove 3 is formed on the top of the guide seat 2. A support rod 4 is slidably installed inside the guide groove 3. A top plate 5 is fixedly connected to the top of the support rod 4. A sliding groove 6 is formed at the front end of the top plate 5. A sliding rod 7 is fixedly connected inside the sliding groove 6. An electric slider 8 is slidably installed on the surface of the sliding rod 7. An installation collar 9 is fixedly connected to the front end of the electric slider 8. A mixing tank 10 is fixedly installed inside the installation collar 9. A dispensing nozzle 11 is fixedly installed at the bottom of the mixing tank 10. An installation plate 12 is fixedly connected to the surface of the dispensing nozzle 11. Protective sleeves 13 are provided on both the left and right sides of the dispensing nozzle 11. A drive assembly 14 is provided on the top of the installation plate 12. A pair of moving grooves 121 are formed on the top of the installation plate 12. The interior of the two moving grooves 121... Each protective sleeve 13 is slidably mounted with a movable plate 122. The ends of the two protective sleeves 13 that are far apart from each other are fixedly connected to the side walls of the two movable plates 122. The interior of each protective sleeve 13 is equipped with absorbent cotton 131. In use, the workpiece to be glued is placed on the worktable 1. The top plate 5 is moved back and forth by the support rod 4. The electric slider 8 drives the mounting ring 9 to move left and right, so that the mixing tank 10 and the dispensing nozzle 11 can move freely above the workpiece for glue dispensing. After glue dispensing is completed, the rotating plate 141 and the connecting rod 142 in the drive assembly 14 work together to make the transmission plate 143 drive the movable plates 122 on both sides to move closer to each other. The movable plates 122 drive the protective sleeves 13 to close and protect the dispensing nozzle 11. The absorbent cotton 131 inside the protective sleeves 13 absorbs the residual glue and prevents glue dripping, thus ensuring the cleanliness of the working environment.

[0020] Further, as shown in Figure 2, the drive assembly 14 includes a rotating plate 141 and a pair of vertical plates 144. The rotating plate 141 is rotatably mounted on the upper surface of the dispensing nozzle 11, and the bottom of the rotating plate 141 is slidably connected to the top of the mounting plate 12. Connecting rods 142 are rotatably mounted on both the front and rear sides of the fixed end of the rotating plate 141. The other ends of the two connecting rods 142 are hinged to transmission plates 143. The bottoms of the two transmission plates 143 are fixedly connected to the tops of the two moving plates 122, respectively. The two vertical plates 144 are fixedly connected to the left and right ends of the mounting plate 12, respectively. A cylinder 145 is fixedly mounted on the right end of the right vertical plate 144. The output end of the cylinder 145 passes through the right side wall of the vertical plate 144 and is fixedly connected to the right end of the right transmission plate 143. Next, the cylinder 145 pushes the right transmission plate 143 to move. The right transmission plate 143 drives the rotating plate 141 to rotate through the right connecting rod 142. The rotating plate 141 drives the left transmission plate 143 to move through the left connecting rod 142, so that the two transmission plates 143 move closer to each other. This causes the moving plate 122 to move closer to each other along the moving groove 121, which in turn causes the protective sleeves 13 on both sides to close, so that the lower end of the glue nozzle 11 is located inside the protective sleeve 13. This not only protects the glue nozzle 11, but also allows the absorbent cotton 131 inside the protective sleeve 13 to absorb residual glue and prevent glue leakage. The absorbent cotton 131 can be attached to the inside of the protective sleeve 13 with Velcro, making it easy to replace and reducing the cleaning burden on the staff.

[0021] A screw 31 is rotatably installed inside the left guide groove 3. The surface of the screw 31 is threadedly connected to the lower end of the left support rod 4. A drive motor 21 is fixedly installed at the front end of the left guide seat 2. The output end of the drive motor 21 passes through the front side wall of the guide seat 2 and is fixedly connected to the front end of the screw 31. Glue storage tanks 15 are fixedly installed on both the left and right sides of the top plate 5. The front ends of the two glue storage tanks 15 are fixedly connected to glue delivery hoses 16. The other ends of the two glue delivery hoses 16 are connected to the top of the mixing tank 10. During glue dispensing, the glue in the glue storage tank 15 enters the mixing tank 10 through the glue delivery hoses 16. The mixing tank 10 uses a stirring structure to make the glue evenly mixed. The drive motor 21 drives the screw 31 to rotate. The screw 31 drives the support rod 4 to move back and forth along the guide groove 3. In conjunction with the electric slider 8, the mounting collar 9 moves left and right along the slide rod 7, so that the glue nozzle 11 can move freely above the workpiece during glue dispensing, which meets the corresponding glue dispensing work. The structure is simple, the operation is convenient, and the practicality of the device is improved.

[0022] The working principle of this utility model is as follows: When in use, the workpiece to be glued is placed on the top of the workbench 1. The glue in the storage tank 15 is transported to the mixing tank 10 through the glue delivery hose 16 and mixed evenly. The drive motor 21 is started, and the screw 31 drives the support rod 4 to move back and forth. In conjunction with the electric slider 8, the mounting collar 9 is moved left and right, moving the glue nozzle 11 above the workpiece for glue filling. After glue filling is completed, the cylinder 145 is started. Through the cooperation of the rotating plate 141 and the connecting rod 142, the moving plate 122 drives the protective sleeve 13 to close, protecting the glue nozzle 11 inside the protective sleeve 13. The glue absorbent cotton 131 inside the protective sleeve 13 absorbs the glue, preventing glue dripping and ensuring the cleanliness of the working environment.
