Description

Technical Field

[0001] The utility model relates to the technical field of mixing, in particular to a planetary cement mortar mixer. Background Art

[0002] Planetary cement mortar mixer is a kind of equipment specially used for cement mortar mixing. It is widely used in laboratories and production lines in cement, concrete, building materials and other industries. It is called planetary cement mortar mixer because it adopts planetary motion trajectory, that is, the mixing blades rotate around the central axis of the mixing barrel while the mixing barrel also rotates. This motion mode can make the materials more evenly and strongly squeezed and turned during the mixing process, thereby improving the mixing efficiency and quality.

[0003] However, this type of mixer has the problem that the contact area and angle between the traditional stirring blade and the material are fixed, and the stirring method may have dead angles, resulting in the problem that the material cannot be fully mixed in some positions. The patent number CN220677418U in the prior art is a material rapid mixer, which is equipped with a second motor, a second gear, a T-column, and a transmission belt. The two ends of the transmission belt are respectively arranged on the outside of the shaft of the second motor and the inside of the T-column. The rotation of the shaft of the second motor drives the outer transmission belt to rotate, thereby driving the inner meshing second gear to rotate, and the second gear drives the stirring blade to rotate. The stirring blade with a changeable rotation angle can better cut, grab and stir the material, increase the contact area with the material, thereby solving the above problem.

[0004] However, after using this mixer, the finished product in the mixing barrel needs to be completely taken out, and then raw materials are added thereto. After the raw materials are added, the mixer is used again to mix the raw materials. During the process of taking out the finished product and adding raw materials, the equipment is in a shutdown state, which affects the processing efficiency of the equipment. Moreover, when the raw materials to be mixed are different from those mixed last time, the mixing barrel needs to be additionally cleaned during the process of taking out the finished product and adding raw materials, thereby further increasing the downtime of the equipment. Therefore, it does not meet the existing needs, and we have proposed a planetary cement mortar mixer. Utility Model Content

[0010] The lower end surface of the mixing barrel is connected to a movable plate, and an internal threaded through hole penetrating the movable plate is provided in the middle position of the front end surface of the movable plate. The movable plate is sleeved on the outer surface of the threaded rod through the internal threaded through hole, and the external thread of the threaded rod matches the internal thread of the internal threaded through hole.

Through the above technical solution, the mixing barrel can be accurately aligned with the telescopic mixing rod, thereby improving the accuracy of the equipment during operation.

DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1 As shown, the utility model provides a planetary cement mortar mixer, comprising a mixer body 1, a rectangular opening 20 penetrating the mixer body 1 is provided on one side of the front end surface of the mixer body 1, a mixing barrel replacement mechanism is provided inside the rectangular opening 20, and the mixing barrel replacement mechanism comprises two mixing barrels 19 and a synchronous moving mechanism, and the two mixing barrels 19 can be synchronously driven to move forward or backward through the synchronous moving mechanism;

[0025] A telescopic stirring rod 21 is provided in the middle position above the second stirring barrel 19 from left to right.

[0026] As the preferred technical solution of this embodiment, Figure 3 As shown, the synchronous moving mechanism includes a circular frame 2, a stepper motor 10 is fixedly installed on one side inside the circular frame 2, the output shaft of the stepper motor 10 is connected to a synchronous rotating shaft 9 through a coupling, a synchronous sprocket B7 is fixedly sleeved on the outer surface of the synchronous rotating shaft 9, a synchronous sprocket A6 is provided below the synchronous sprocket B7, and the synchronous sprocket B7 and the synchronous sprocket A6 are serially driven through a synchronous chain 8; when in use, connect the power supply, and when the raw materials inside the mixing barrel 19 located below the telescopic stirring rod 21 are mixed, start the stepper motor 10, and the stepper motor 10 can drive the synchronous rotating shaft 9 connected thereto and the synchronous sprocket B7 fixedly sleeved on the outer surface of the synchronous rotating shaft 9 to rotate, and when the synchronous sprocket B7 rotates, the synchronous sprocket A6, which is serially driven with it through the synchronous chain 8, will rotate synchronously therewith.

[0027] The axis of the synchronous sprocket A6 is connected to a threaded rod shaft, and the rear end surface of the threaded rod shaft is fixedly connected to a threaded rod 4; when the synchronous sprocket A6 rotates, the threaded rod shaft fixed thereto will also rotate accordingly, and when the threaded rod shaft rotates, the threaded rod 4 fixed thereto will also rotate accordingly.

[0028] The lower end face of the mixing barrel 19 is connected to a movable plate 5, and an internal threaded through hole 11 penetrating the movable plate 5 is provided in the middle position of the front end face of the movable plate 5. The movable plate 5 is sleeved on the outer surface of the threaded rod 4 through the internal threaded through hole 11, and the external thread of the threaded rod 4 matches the internal thread of the internal threaded through hole 11.

[0029] As the preferred technical solution of this embodiment, Figure 1 As shown, a guide rod 3 is provided on both sides of the threaded rod 4 for laterally moving through the movable plate 5, and both ends of the guide rod 3 are fixed to the circular frame 2; since the guide rod 3 laterally penetrates the movable plate 5, the movable plate 5 itself cannot rotate, so that it can only move forward and backward. When the threaded rod 4 rotates, the movable plate 5 that cannot rotate itself will move forward and backward on the outer surface of the threaded rod 4 through the internal thread transmission of the internal threaded through hole 11. When the mixing barrel 19 needs to be replaced, the two movable plates 5 are moved backward synchronously. As the two movable plates 5 move, the mixing barrel 19 located on the upper end surface thereof will also move synchronously.

[0030] As the preferred technical solution of this embodiment, Figure 4 As shown, a sealing positioning plate 12 is fixedly provided on both sides of the upper end surface of the movable plate 5, a spring groove 13 is provided on the upper side of the sealing positioning plate 12, a metal ring 15 is provided inside the spring groove 13 to fit the inner wall thereof, a spring 14 is connected between the lower end surface of the metal ring 15 and the inner wall of the spring groove 13; a metal rod 16 is connected to the axis of the metal ring 15, an inclined surface positioning block 17 is fixedly provided on the upper end surface of the metal rod 16, an inclined surface positioning groove 18 is provided on the inner wall of the rectangular through opening 20 on the outer side of the top end of the third and fourth inclined surface positioning blocks 17 from left to right, and the surface of the inclined surface positioning block 17 facing the inclined surface positioning groove 18 and the surface of the inclined surface positioning groove 18 facing the inclined surface positioning groove 18 are connected to the inner wall of the rectangular through opening 20. The surfaces of the surface positioning block 17 are all inclined surfaces; as the two movable plates 5 move, the sealing positioning plate 12 fixed on the upper end surface thereof will also move accordingly, and as the sealing positioning plate 12 moves, the inclined surface positioning block 17 located on the upper end surface thereof will also move accordingly, and when the inclined surface positioning block 17 stuck in the inclined surface positioning groove 18 moves backward, the inclined surface on the outer surface of the inclined surface positioning block 17 and the inner wall of the inclined surface positioning groove 18 can push the inclined surface positioning block 17 downward until it completely leaves the inside of the inclined surface positioning groove 18, and the metal ring 15 connected to the inclined surface positioning block 17 through the metal rod 16 will also drop accordingly during the downward movement of the inclined surface positioning block 17, and squeeze the spring 14;

[0031] When the second inclined surface positioning block 17 from the left to the right is about to move to the position of the first inclined surface positioning groove 18 from the left to the right, the inclined surface positioning block 17 will be pushed downward and squeeze the spring 14 through the inclined surface on the outer surface of the inclined surface positioning block 17. When the second inclined surface positioning block 17 from the left to the right moves to the bottom of the first inclined surface positioning groove 18 from the left to the right, the spring force of the squeezed spring 14 will push the inclined surface positioning block 17 upward to make it stuck in the inside of the inclined surface positioning groove 18. However, at this time, the first mixing barrel 19 from the left to the right has not moved to the bottom of the telescopic mixing rod 21, so it is necessary to continue to move the movable plate 5. When the sealing positioning plate 12 located in front and behind the first mixing barrel 19 from the left to the right is When the two inclined positioning blocks 17 on the upper end face are both inserted into the inclined positioning grooves 18, the mixing barrel 19 moves to the middle position below the telescopic stirring rod 21, and then the raw materials in the mixing barrel 19 newly moved thereto can be stirred by the telescopic stirring rod 21. In the stirring process, the finished mixing product in the mixing barrel 19 that has been moved to the outside of the mixer body 1 can be taken out, and raw materials can be added thereto. The above technical solution reduces the time gap during the operation of the mixer body 1, thereby improving its processing efficiency. In addition, the positioning of the inclined positioning blocks 17 and the inclined positioning grooves 18 can accurately align the mixing barrel 19 with the telescopic stirring rod 21, thereby improving the accuracy of the result.

[0032] A metal cover is provided in front of the stepper motor 10 and is located on the outer surface of the circular frame 2, and the circular frame 2 and the metal cover are fixed by screws; the metal cover can protect the stepper motor 10, and when the stepper motor 10 fails, it can be repaired by removing the metal cover.
