[0024] The multi-wire cutting machine mortar mixing system provided by the present invention is now described.

[0025] like Figures 1 to 3 As shown, an embodiment of the present invention provides a multi-wire cutting machine mortar mixing system, including a mixing drum 1 and a mounting frame 2 arranged above the mixing drum 1; a shaft body 11 is vertically rotatably connected in the mixing drum 1, and a driving motor 21 for driving the shaft body 11 to rotate is arranged on the mounting frame 2; a thread is arranged on the outer peripheral surface of the shaft body 11, and a connecting ring 3 is threadedly connected to the shaft body 11, and a sealing folding cover 31 is arranged between the bottom surface of the connecting ring 3 and the bottom of the mixing drum 1, and between the top surface of the connecting ring 3 and the mounting frame 2; a plurality of stirring paddles 32 are rotatably connected to the outer peripheral surface of the connecting ring 3, and the rotation axis of the stirring paddle 32 is perpendicular to the axis of the shaft body 11; a accommodating cavity 321 is downwardly opened on one side of the stirring paddle 32, and a rotating component 4 for driving the stirring paddle 32 to rotate is arranged on the connecting ring 3; a retaining component 5 for fixing it relatively to the shaft body 11 is arranged on the connecting ring 3, and a lifting mechanism 6 for driving the connecting ring 3 to be lifted and lowered is arranged on the mounting frame 2.

[0026] Compared with the prior art, the multi-wire cutting machine mortar mixing system provided in this embodiment drives the shaft body 11 to rotate through the driving motor 21, and the shaft body 11 drives the connecting ring 3 to rotate through its own thread and the retaining component 5, and the connecting ring 3 drives multiple stirring paddles 32 to stir the bottom of the mixing drum 1, and at the same time, the mortar in the lower layer of the mixing drum 1 enters each accommodating cavity 321; after the lower layer is stirred for a period of time, the driving motor 21 stops working, the retaining component 5 releases the fixation between the connecting ring 3 and the shaft body 11, and the lifting mechanism 6 is used to lift the mortar. Drive the connecting ring 3 up to the upper layer of mortar, and keep the component 5 to fix the connecting ring 3 and the shaft body 11 relatively again. At the same time, the rotating component 4 drives each stirring paddle 32 to rotate 180° so that the opening of the accommodating chamber 321 faces downward. At this time, the driving motor 21 drives the shaft body 11 to rotate in the same direction again, and the opening of the accommodating chamber 321 deviates from the rotation direction of the stirring paddle 32. Therefore, the mortar in the accommodating chamber 321 will flow out through the opening into the upper layer of mortar and be stirred; repeating the above steps can achieve repeated stirring and mixing of the lower layer mortar and the upper layer mortar in the mixing drum 1, thereby improving the mixing uniformity of the upper layer mortar and the lower layer mortar.

[0027] like Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The stirring paddle 32 is provided with a sharp edge on the side away from the opening of the accommodating chamber 321. After the stirring paddle 32 rises to the upper layer of mortar and rotates 180 degrees, the driving motor 21 drives the shaft 11 to rotate in the same direction so that the sharp edge of the stirring paddle 32 can more thoroughly stir the upper layer of mortar and the mortar flowing out of the accommodating chamber 321, further improving the mixing uniformity of the mortar.

[0028] like Figure 2 and Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The rotating assembly 4 includes a gear 41, a rack 42 and a reset member 43. The end of the stirring paddle 32 inserted into the connecting ring 3 is cylindrical. The gear 41 is coaxially fixed to the end of the stirring paddle 32. The rack 42 is vertically slidably connected to the connecting ring 3 and is always engaged with the gear 41. The top of the rack 42 slides downward when pressed down by the mounting frame 2, and the reset member 43 is used to drive the rack 42 to reset.

[0029] When the lifting mechanism 6 drives the connecting ring 3 to move upward to near the mounting frame 2, the top of the rack 42 is limited by the mounting frame 2 and moves downward, driving the gear 41 and the propeller to rotate at the same time. When the gear 41 and the stirring paddle 32 rotate 180°, the connecting ring 3 stops rising, and the stirring paddle 32 is at the upper mortar. When the lifting mechanism 6 drives the connecting ring 3 to descend, the reset member 43 gradually drives the rack 42 to reset, so that the gear 41 and the stirring paddle 32 are reversed and reset, which improves the rotation efficiency of the stirring paddle 32 as a whole, without the need for an additional power source.

[0030] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The reset member 43 includes a force plate 431 and a strong spring 432. The force plate 431 is fixed to the bottom end of the rack 42. The strong spring 432 is sleeved on the rack 42. The strong spring 432 is connected between the bottom surface of the connecting ring 3 and the force plate 431. When the stirring paddle 32 is in the initial state, the strong spring 432 is in a natural state.

[0031] When the rack 42 is not subjected to force, it is kept stationary by the friction between itself and the connecting ring 3 and the elastic force of the strong spring 432 .

[0032] When the top end of the rack 42 is limited by the mounting frame 2, the force plate 431 is driven down, and the strong spring 432 is stretched at this time; when the lifting mechanism 6 drives the connecting ring 3 to descend, the retraction force of the strong spring 432 drives the rack 42 to reset, so as to realize the reverse reset of the gear 41 and the stirring paddle 32.

[0033] like Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: An auxiliary ring 44 coaxial with the shaft body 11 is rotatably provided on the bottom surface of the mounting frame 2 , and the top of the rack 42 is used to contact the bottom surface of the auxiliary ring 44 .

[0034] When the stirring paddle 32 rotates and stirs the mortar at the last location, the top of the rack 42 presses against the auxiliary ring 44 to make it rotate relative to the mounting frame 2, thereby reducing the wear on the end of the rack 42 and improving the rotation convenience of the connecting ring 3.

[0035] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The retaining assembly 5 includes a micro-cylinder 51, a top block 52, a lever 53 and a return spring 54. The micro-cylinder 51 is invertedly installed above the connecting ring 3, and the top block 52 is fixed to the bottom of the piston rod of the micro-cylinder 51; the lever 53 is rotatably connected to the connecting ring 3, and the top block 52 is used to press down the end of the lever 53 away from the shaft body 11, and the return spring 54 is connected between the top surface of the connecting ring 3 and the end of the lever 53 away from the shaft body 11; a vertical groove 111 is opened on the side of the shaft body 11 facing the lever 53, and when the lever 53 is pressed down by the top block 52, the end of the lever 53 rotates into the vertical groove 111.

[0036] When the micro-cylinder 51 drives the top block 52 to press the lever 53 downward to rotate the end of the lever 53 into the vertical groove 111, the shaft body 11 and the connecting ring 3 are in a relatively fixed state, and the driving motor 21 can drive the connecting ring 3 to rotate through the shaft body 11. When the connecting ring 3 needs to be raised or lowered, the micro-cylinder 51 drives the top block 52 to rise, so that the reset spring 54 drives the lever 53 to rotate and reset to be out of the vertical groove 111, and the connecting ring 3 can be driven to be raised or lowered through the lifting mechanism 6, thereby improving the efficiency of fixing or releasing the fixing between the connecting ring 3 and the shaft body 11.

[0037] Specifically, the lifting mechanism 6 is used to vertically guide the connecting ring 3. At this time, the driving motor 21 drives the shaft body 11 to rotate, and the cooperation between the thread of the shaft body 11 and the guide of the lifting mechanism 6 enables the connecting ring 3 to be lifted and lowered.

[0038] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: A stress groove 33 connected to the vertical groove 111 is formed on the top surface of the connecting ring 3. When the end of the lever 53 away from the top block 52 is in the initial state, it is located in the stress groove 33. When the lever 53 is pressed down by the top block 52, the lever 53 is located in the stress groove 33 and the vertical groove 111 at the same time.

[0039] When the lever 53 is located in the vertical groove 111 and the force groove 33 at the same time, the rotation of the shaft body 11 can be directly transmitted to the connecting ring 3 through the lever 53, reducing the burden of the rotating connecting structure of the lever 53 itself.

[0040] like Figure 2 and Figure 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The lifting mechanism 6 includes a top ring 61, a bottom ring 62, a guide rod 63 and a locking assembly 64; the top ring 61 is rotatably connected in the mounting frame 2, the bottom ring 62 is rotatably connected to the bottom of the mixing drum 1, the guide rod 63 is vertically fixed between the top ring 61 and the bottom ring 62, the top ring 61 and the bottom ring 62 are both coaxially arranged with the shaft body 11, and the guide rod 63 passes through the connecting ring 3; the locking assembly 64 is arranged on the mounting frame 2 and is used to fix the top ring 61.

[0041] When the locking assembly 64 does not fix the top ring 61, the shaft body 11 drives the connecting ring 3 to rotate, and the connecting ring 3 drives the top ring 61 and the bottom ring 62 to rotate synchronously through the guide rod 63. When the connecting ring 3 needs to be lifted or lowered, the locking assembly 64 fixes the top ring 61 relative to the mounting frame 2, and the guide rod 63 plays a role of vertical guidance for the connecting ring 3. When the shaft body 11 drives the connecting ring 3 to rotate again, the connecting ring 3 can be lifted or lowered along the guide rod 63, thereby improving the switching efficiency of the connecting ring 3 in the rotating or lifting state.

[0042] like Figure 5 to Figure 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The locking assembly 64 includes an outer ring 641, an extrusion block 642, a locking plate 643 and a driving member 644; the outer ring 641 is rotatably connected in the mounting frame 2 and is coaxially located on the outer side of the top ring 61, at least two locking plates 643 are provided and are relatively slidably connected in the mounting frame 2, the sliding direction of the locking plates 643 is perpendicular to the axis of the top ring 61, and the locking plates 643 are located between the outer ring 641 and the top ring 61; a plurality of extrusion blocks 642 are provided and fixed on the inner circumference of the outer ring 641, and a receiving groove 6431 is opened on the outer side of each locking plate 643, the extrusion block 642 is hemispherical and is located in the corresponding receiving groove 6431, at this time, the inner side of the locking plate 643 is close to the top ring 61; the driving member 644 is provided on the mounting frame 2 and is used to drive the outer ring 641 to rotate; when the outer ring 641 drives all the extrusion blocks 642 to disengage from the receiving groove 6431, the inner side of the locking plate 643 presses the top ring 61 tightly to fix it.

[0043] Furthermore, in this embodiment, the driving member 644 is a cylinder or a hydraulic cylinder, and a fixing plate is fixed to the outer peripheral surface of the outer ring 641. One end of the driving member 644 is hinged to the mounting frame 2, and the other end is hinged to the fixing plate. Starting the driving member 644 to extend and retract can drive the outer ring 641 to rotate.

[0044] When it is necessary to drive the connecting ring 3 to rise or fall, start the driving member 644 to drive the outer ring 641 to rotate, and the outer ring 641 drives all the extrusion blocks 642 to disengage from the accommodating groove 6431 and squeeze the locking plate 643. After being squeezed, the locking plate 643 moves toward the top ring 61 and tightens it to fix it, thereby improving the convenience of fixing the top ring 61; and the back side of each locking plate 643 is squeezed by multiple extrusion blocks 642 at the same time, thereby making the friction force on the contact surface between the locking plate 643 and the outer ring 641 more uniform, thereby improving the clamping and fixing effect of the locking plate 643 on the top ring 61.

[0045] like Figure 5 to Figure 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The inner wall of the outer ring 641 is provided with a plurality of installation grooves 6411 , each of which is provided with a positioning coil spring 645 connected to the locking plate 643 . When the positioning coil spring 645 is in a natural state, the extrusion block 642 is located in the corresponding accommodation groove 6431 .

[0046] When the driving member 644 drives the outer ring 641 to reverse and reset, the positioning coil spring 645 can drive the corresponding locking plate 643 to reset, so that the extrusion block 642 can be inserted into the corresponding extrusion groove again.
