DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example 1

[0029] A single-component screw valve with precise dispensing, such as Figure 1-Figure 6As shown, it includes an output motor 1, a connecting box 5, and a transparent storage tube 6. The output end of the output motor 1 is connected to a glue discharge assembly. The bottom outer wall of the transparent storage tube 6 is connected to a connecting tube 4. The other end of the connecting tube 4 is connected to the glue discharge assembly. A fixing ring 11 is welded to the outer side wall of the connecting box 5. A fixing ring 2 12 is slidably connected to the outer side wall of the connecting box 5. A movable horizontal plate 8 is slidably connected to the inner side wall of the connecting box 5. A connecting rod 20 is rotatably connected to the outer side wall of the movable horizontal plate 8. The side wall of the connection box 5 is provided with an oblique groove 9, the connection rod 20 cooperates with the oblique groove 9, and the other end of the connection rod 20 is connected to the fixed ring 2 12, the inner wall of the connection box 5 is rotatably connected with a lead screw 10, the lead screw 10 is connected to the movable horizontal plate 8 through a nut, the fixed ring 11 and the fixed ring 2 12 are matched with the output motor 1 and the transparent storage tube 6 through a pair of clamps, the outer side wall of the fixed ring 11 is provided with a plug hole 14, and the outer side wall of the fixed ring 2 12 is welded with an oblique plug rod 13;

[0030] When in use, the output motor 1 and the transparent storage tube 6 are respectively placed outside the fixed ring 11 on both sides, and then the screw 10 is rotated to move the movable cross plate 8. With the cooperation of the connecting rod 20 and the inclined groove 9, the fixed ring 2 12 moves obliquely, and then the oblique insertion rod 13 is inserted into the socket 14, and then the device is installed as a whole on the outside of the main control device. The oblique cooperation between the oblique insertion rod 13 and the socket 14 can make the fixed ring 11 and the fixed ring 2 12 able to resist the influence of lateral vibration well, and at the same time facilitate the disassembly and assembly of the output motor 1 and the transparent storage tube 6, and only the screw 10 needs to be rotated.

[0031] The glue discharging assembly includes a mounting seat 2, an output pipe 3, and a connecting seat 21. The connecting seat 21 is fixed to the outer wall of the bottom of the output motor 1 by bolts, the mounting seat 2 is fixed to the outer wall of the bottom of the connecting seat 21 by bolts, the output pipe 3 is welded to the outer wall of the bottom of the mounting seat 2, and the inner wall of the mounting seat 2 is rotatably connected with an eccentric screw 7, and the eccentric screw 7 is connected to the output end of the output motor 1;

[0032] When in use, the output motor 1 can be turned on to drive the eccentric screw 7 inside the mounting seat 2 to rotate, so that the rubber material flowing out of the transparent storage tube 6 through the connecting tube 4 is gradually pushed out and quantitatively transported. At the same time, when reversing, the rubber material will not drip or draw, ensuring the cleanliness of the outlet.

[0033] The inner side wall of the transparent storage tube 6 is slidably connected with a floating plate 16, the outer side wall of the transparent storage tube 6 is threadedly connected with a closing cover 22, an elastic rope 19 is bonded between the floating plate 16 and the bottom inner wall of the transparent storage tube 6, a pull rope 15 is bonded to the top outer wall of the floating plate 16, the pull rope 15 is movably connected to the inner wall of the closing cover 22, the other end of the pull rope 15 is bonded with a hook 17, and a fixing handle 18 is bonded to the outer side wall of the transparent storage tube 6, and the hook 17 cooperates with the fixing handle 18;

[0034] The rotatable closing cover 22 is opened, and the rubber is added into the transparent storage tube 6. At the same time, the connection between the hook 17 and the fixed handle 18 is cancelled. After the rubber is added, the floating plate 16 floats up and the elastic rope 19 is stretched straight. Then, the output motor 1 is turned on to output the rubber. The rubber in the transparent storage tube 6 decreases and the floating plate 16 drops accordingly. At this time, it is convenient for the user to clearly understand the amount of material remaining in the transparent storage tube 6. When it is necessary to add material again, the hook 17 at the other end of the pull rope 15 is pulled to hook the outside of the fixed handle 18. Then, the closing cover 22 is opened to add material to ensure that the floating plate 16 can float on the top of the material, and then the material output continues.

[0035] Working principle: the output motor 1 and the transparent storage tube 6 are respectively placed outside the fixed ring 11 on both sides, and then the lead screw 10 is rotated to move the movable cross plate 8. With the cooperation of the connecting rod 20 and the inclined groove 9, the fixed ring 12 moves obliquely, and then the oblique insertion rod 13 is inserted into the insertion hole 14. Then the device is installed as a whole outside the main control device, and the closing cover 22 is turned to open it. The rubber is added into the transparent storage tube 6, and the connection between the hook 17 and the fixed handle 18 is cancelled. After the rubber is added, the floating plate 16 floats up and the elastic rope 19 is stretched straight. Then the output motor 1 is turned on to gradually push out the rubber and convey it quantitatively. At the same time, when reversing, the rubber will not leak or draw, ensuring the cleanliness of the outlet.
