Specific implementation manner

[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0024] As Figures 1-5 shown, a protective cement packaging machine provided by an embodiment of the present utility model includes a bottom beam 1. An installation groove 2 is provided on the outer wall of one side of the bottom beam 1. A double-threaded screw 7 is connected to the inside of the installation groove 2 through a bearing. Two slide blocks 3 are slidably connected to the inside of the installation groove 2. The double-threaded screw 7 is threadedly connected to the slide block 3. One end of the bottom beam 1 is fixed with a motor 4. The output shaft of the motor 4 is key-connected to the double-threaded screw 7. A connecting arm 5 is fixed to the outer wall of one side of the slide block 3. A first arc plate 6 is fixed to the top of the connecting arm 5. A clamping mechanism is provided on the top of the first arc plate 6.

[0025] Specifically, in this embodiment, it includes a bottom beam 1. An installation groove 2 is provided on the outer wall of one side of the bottom beam 1. A double-threaded screw rod 7 is connected to the inside of the installation groove 2 through a bearing. The double-threaded screw rod 7 has two thread patterns with opposite spiral directions. Two sliders 3 are slidably connected to the inside of the installation groove 2. The sliders 3 slide linearly inside the installation groove 2 through slide rails. The double-threaded screw rod 7 is threadedly connected to the sliders 3. When the double-threaded screw rod 7 rotates, it can drive the sliders 3 to move away from or close to each other. One end of the bottom beam 1 is fixed with a motor 4. The output shaft of the motor 4 is key-connected to the double-threaded screw rod 7. The motor 4 drives the double-threaded screw rod 7 to rotate. A connecting arm 5 is fixed to the outer wall of one side of the slider 3. An arc plate one 6 is fixed to the top of the connecting arm 5. The arc plate one 6 is a half circle. The bagged cement is placed between the two arc plates one 6, so that the arc plate one 6 can support and protect the bagged cement, preventing the bagged cement from tipping over before being sealed. And when the two arc plates one 6 are combined, they form a complete cylinder. The diameter of the cylinder is slightly larger than the diameter of the bagged cement to prevent the arc plate one 6 from squeezing the bagged cement. A clamping mechanism is provided on the top of the arc plate one 6 to fix the cement packaging bag.

[0026] A protective cement packaging machine provided by the present utility model drives the double-threaded screw rod 7 to rotate through the motor 4, so that the double-threaded screw rod 7 drives the two arc plates one 6 to approach each other through the sliders 3 and the connecting arm 5, realizing the effect of the arc plate one 6 supporting the bagged cement and preventing the filled cement packaging bag from tipping over.

[0027] In another embodiment provided by the present utility model, a bottom plate 22 is fixed to one side of the bottom beam 1, a top plate 8 is fixed to the top of the bottom plate 22, and the top plate 8 and the bottom plate 22 are supported by columns. A discharge pipe 10 is fixed inside the top plate 8. A packaging bag is sleeved on the bottom of the discharge pipe 10. A hopper 9 is fixed to the top end of the discharge pipe 10, and the quantitative cement to be packaged is poured into the hopper 9; the clamping mechanism includes quarter-circle arc plates two 14 located around the discharge pipe 10. The number of the arc plates two 14 is four, and when the four arc plates two 14 approach each other, they can surround the discharge pipe 10. Fixed rods 15 distributed symmetrically about the center are fixed to the outer wall of the bottom of the top plate 8. The number of the fixed rods 15 is four. A plug-in column 16 is movably inserted into the fixed rod 15. One end of the plug-in column 16 is fixed to the arc plate two 14, and when the plug-in column 16 moves, it drives the arc plate two 14 to move; cylinders 13 are fixed to the outer wall of the top of the top plate 8. The number of the cylinders 13 is preferably two, and the two cylinders 13 are symmetrically installed about the central axis of the discharge pipe 10. An installation ring 11 is arranged outside the discharge pipe 10. The output end of the cylinder 13 penetrates through the top plate 8 and is fixed to the installation ring 11. The cylinder 13 is used to drive the installation ring 11 to move up and down. Wedge blocks two 21 distributed symmetrically about the center are fixed to the outer wall of the bottom of the installation ring 11. The number of the wedge blocks two 21 is four. A wedge block one 20 is fixed to the end of the plug-in column 16 away from the arc plate two 14. The four wedge blocks two 21 correspond to the four wedge blocks one 20, and the wedge block one 20 is adapted to the wedge block two 21. When the installation ring 11 moves downward, the wedge block two 21 can squeeze the wedge block one 20. By driving the installation ring 11 to move downward through the cylinder 13, the wedge block two 21 at the bottom of the installation ring 11 squeezes the wedge block one 20, so that the wedge block one 20 drives the arc plate two 14 to clamp and fix the packaging bag, making the packaging bag more firmly sleeved on the discharge pipe 10; a spring 19 is sleeved outside the plug-in column 16, and the spring 19 is located between the wedge block one 20 and the fixed rod 15; guide columns 12 distributed symmetrically about the center are fixed to the outer wall of the top of the installation ring 11, and a guide sleeve 23 is fixed to the outer wall of the top of the top plate 8. The guide columns 12 are movably inserted into the guide sleeve 23. The guide columns 12 are used to make the installation ring 11 move more stably up and down. By setting the spring 19 to apply an elastic force to the wedge block one 20, after the wedge block two 21 and the wedge block one 20 are separated, the arc plate two 14 can automatically separate from the discharge pipe 10 through the elastic force of the spring 19, so that there is enough gap between the arc plate two 14 and the discharge pipe 10 for the packaging bag to be sleeved in, achieving the effect of more convenient sleeving of the packaging bag on the discharge pipe 10;A limiting post 18 is inserted inside the fixed rod 15. A limiting groove 17 is formed on the outer wall of one side of the insertion post 16. One end of the limiting post 18 extends into the inside of the limiting groove 17. By matching the limiting post 18 with the limiting groove 17, the insertion post 16 is prevented from rotating inside the fixed rod 15, so that the four arc plates II 14 can firmly fix the packaging bag outside the discharge pipe 10.

[0028] Working principle: When it is necessary to pack cement into a bag, first, the packaging bag is sleeved outside the bottom end of the discharge pipe 10, and the packaging bag is located between the arc plate II 14 and the discharge pipe 10. Then, the cylinder 13 drives the mounting ring 11 to move downward, so that the mounting ring 11 drives the wedge block II 21 to move. The wedge block II 21 squeezes the wedge block I 20, so that the wedge block I 20 drives the insertion post 16 to approach the discharge pipe 10. Further, the arc plate II 14 at one end of the insertion post 16 clamps and fixes the packaging bag. Then, a fixed weight of cement is poured into the hopper 9, so that the cement flows from the discharge pipe 10 into the inside of the packaging bag. When the cement bagging is completed, the motor 4 drives the double-threaded screw rod 7 to rotate. The rotation of the double-threaded screw rod 7 drives the two sliders 3 to move closer to each other, so that the two arc plates I 6 approach each other, achieving the effect of supporting the packaging bag by the arc plates I 6 and preventing the packaging bag filled with cement from tipping over.

[0029] Only some exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
