[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-6 This is the first embodiment of the present invention, which provides an insulating adhesive preparation machine to prevent the mixing tube from dripping adhesive. It includes a base 1, a T-shaped plate 2 fixedly installed on the top of the base 1, an injection head 5 fixedly connected to the front side of the top of the T-shaped plate 2, an injection cavity 51 symmetrically opened inside the upper part of the injection head 5, an adhesive conveying groove 52 opened at the bottom of the injection cavity 51, an adhesive filling groove 54 opened at the bottom of the adhesive conveying groove 52, and an adhesive mixing tube 6 provided at the bottom of the adhesive filling groove 54.

[0027] The glue dispensing head 5 includes a flow-stopping mechanism 7. A first ring 71 is fixedly connected to the middle of the inner wall of the glue dispensing groove 52. A first spring 72 is movably connected to the bottom end of the first ring 71. A rubber ball 73 is fixedly connected to the bottom end of the first spring 72. The outer surface of the rubber ball 73 is slidably connected to the inner wall of the glue dispensing groove 52.

[0028] A second ring 74 is fixedly connected to the inner wall of the mixing tube 6. A slide rod 75 is slidably connected to both sides of the second ring 74. A second spring 76 is sleeved on the outer surface of the slide rod 75. A cross plate 77 is fixedly connected to the top of the slide rod 75. A movable rod 78 is movably connected to the bottom of the cross plate 77. A semi-circular baffle 79 is movably connected to the bottom of the movable rod 78. The semi-circular baffle 79 is rotatably connected to the inner wall of the mixing tube 6 through a rotating shaft 710.

[0029] Piston bodies 55 are symmetrically installed at the top of T-shaped plate 2. The telescopic shaft of piston body 55 passes through the top of T-shaped plate 2 and is fixedly connected to piston plate 56. Piston plate 56 is slidably connected to the inner wall of glue injection cavity 51. Glue dispensing valve 53 is fixedly installed above the inner wall of glue delivery groove 52.

[0030] Specifically, the insulating adhesive flows in from the two dispensing chambers 51 respectively. When the dispensing chambers 51 are full, the filling valve 42 is closed and the potting valve 53 is opened. Then the piston body 55 is started. Through the sliding of the piston plate 56, the adhesive is squeezed and flows through the dispensing tank 52 and the potting valve 53 to the potting tank 54. Finally, it enters the mixing tube 6 for mixing and is injected into the product.

[0031] As the adhesive flows, the pressure of the adhesive overcomes the elastic force of the first spring 72, pressing the rubber ball 73 downwards so that the adhesive can pass smoothly through the glue delivery groove 52. After the glue is injected, under the action of the first spring 72, the rubber ball 73 will move upwards and fit tightly against the bottom of the first ring 71, blocking the glue delivery groove 52 and preventing the adhesive from continuing to flow from the glue injection chamber 51 into the glue filling groove 54. Through the arrangement of the first ring 71, the first spring 72 and the rubber ball 73, the adhesive remaining in the glue filling valve 53 can be separated from the adhesive remaining in the mixing tube 6.

[0032] In the mixing tube 6, when the adhesive enters, it pushes the semi-circular baffle 79 to rotate around the rotating shaft 710, allowing the adhesive to smoothly enter the mixing tube 6 for mixing. During the rotation of the semi-circular baffle 79, it drives the cross plate 77 to move downward through the movable rod 78. The cross plate 77 drives the slide rod 75 to move downward, and compresses the second spring 76. When the adhesive injection stops, under the elastic force of the second spring 76, the slide rod 75 moves upward, driving the cross plate 77 to move upward. Through the movable rod 78, the semi-circular baffle 79 rotates to a horizontal position, blocking the outlet of the mixing tube 6 and preventing the adhesive in the mixing tube 6 from dripping out.

[0033] This design, through a mechanism consisting of a first ring 71, a first spring 72, and a rubber ball 73, can quickly block the flow of adhesive after injection, separating the adhesive remaining in the dispensing valve 53 from the adhesive remaining in the mixing tube 6, preventing adhesive from dripping at the dispensing head 5 and avoiding material waste. Through an anti-drip structure consisting of a second ring 74, a sliding rod 75, a second spring 76, a cross plate 77, a movable rod 78, a semi-circular baffle 79, and a rotating shaft 710, it can automatically seal the outlet of the mixing tube 6 after injection stops, preventing internal residual adhesive from dripping. The anti-drip function can be achieved without manual intervention, effectively improving the automation level of the equipment.

[0034] Reference Figures 1-6 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a quick-release mechanism 8 is provided at the bottom end of the dispensing head 5, and an installation base 81 is fixedly installed at the bottom end of the dispensing head 5. A slot 82 is opened at the bottom end of the installation base 81, and a sealing ring 83 is fixedly connected to the top wall of the slot 82.

[0035] A mixing tube 6 is slidably connected to the inner wall of the slot 82. The mixing tube 6, the mounting base 81 and the glue filling tank 54 are connected. An annular mounting plate 61 is fixedly connected to the outer surface of the mixing tube 6.

[0036] Both sides of the annular mounting plate 61 are threaded with bolts 84, and the top of the bolts 84 is threaded into the interior of the mounting base 81.

[0037] Specifically, when it is necessary to replace the mixing tube 6, first unscrew the bolts 84 on both sides of the annular mounting plate 61. At this time, the annular mounting plate 61 will separate from the mounting base 81. Then, the mixing tube 6 can be pulled downward from the slot 82 to complete the disassembly.

[0038] When installing the new mixing tube 6, align the mixing tube 6 with the slot 82 and insert it to connect the mixing tube 6, the mounting base 81 and the glue filling tank 54. At this time, the annular mounting plate 61 fits against the mounting base 81, and the sealing ring 83 ensures the sealing of the connection. Then tighten the bolt 84 to fix the annular mounting plate 61 on the mounting base 81, thus completing the quick installation of the mixing tube 6.

[0039] Reference Figures 1-6 This is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that: a raw material barrel 3 is symmetrically installed on the rear side of the top of the base 1, a material pump 4 is fixedly installed on the top of the raw material barrel 3, a material pump pipe is fixedly sleeved at the input end of the material pump 4, the bottom end of the material pump pipe extends into the inside of the raw material barrel 3, and a first glue delivery pipe 41 is fixedly sleeved at the output end of the material pump 4.

[0040] One end of the first glue delivery tube 41 is fixedly sleeved with a glue filling valve 42, and one end of the glue filling valve 42 is fixedly sleeved with a second glue delivery tube 43. One end of the second glue delivery tube 43 passes through the top of the T-shaped plate 2 and is fixedly sleeved on the side wall of the glue injection head 5. The second glue delivery tube 43 is connected to the glue injection cavity 51.

[0041] Specifically, the raw material tank 3 contains different raw materials. When the pump 4 is started, the raw materials enter the pump 4 from the pump pipe under the action of the pump 4, and then enter the first glue delivery pipe 41 from the output end of the pump 4. Then the glue filling valve 42 is opened, and the glue liquid enters the second glue delivery pipe 43 from the first glue delivery pipe 41 through the glue filling valve 42. Finally, the glue liquid enters the glue injection chamber 51 from the second glue delivery pipe 43.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
