DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] See also Figure 1-6 A stuffing mixing device for reducing wall sticking includes a mixing drum 1 and a scraping rod 17 for scraping the stuffing on the inner wall of the mixing drum 1. The mixing drum 1 is provided with a mixing rod 10 for mixing the stuffing, and a plurality of mixing rods 10 are connected to the same driving shaft 7.

[0020] The top of the mixing drum 1 is connected to a support frame 2, a driving shaft 7 is rotatably connected to the support frame 2, and a first motor 5 is connected to the support frame 2, and the first motor 5 is used to drive the driving shaft 7 to rotate; The output end of the first motor 5 is connected to a transmission frame 6 , and the bottom end of the transmission frame 6 is connected to the outer side wall of the driving shaft 7 .

[0021] The filling is poured into the mixing drum 1, and then the first motor 5 is controlled. The first motor 5 drives the transmission frame 6 and the driving shaft 7 to rotate synchronously. When the driving shaft 7 rotates, it drives multiple stirring rods 10 connected to the outside to rotate, so as to stir the filling in the mixing drum 1. This method is an existing conventional method for stirring the filling.

[0022] Example 1 This embodiment is an improvement on the conventional method of scraping the fillings from the inner wall of the mixing drum 1. The purpose is to solve the problem that the scraper 17 is in contact with the inner wall of the mixing drum 1 for a long time, resulting in a gap between the inner wall of the mixing drum 1 and the scraper 17.

[0023] The interior of the driving shaft 7 is hollow, and the second motor 4 is connected to the top thereof. The driving shaft 7 is fixedly connected to a fixed cylinder 8, and an extension cylinder 9 is inserted and connected to the fixed cylinder 8. The end of the extension cylinder 9 close to the mixing drum 1 is connected to the scraper 17. The second motor 4 can drive the scraper 17 to move toward the inner wall of the mixing drum 1 and enable the scraper 17 to abut against the inner wall of the mixing drum 1. It should be noted that the height of the poured filling will not exceed the height of the extension cylinder 9.

[0024] The second motor 4 is in the transmission frame 6, and the output end of the second motor 4 is connected to the output shaft 18, and the output shaft 18 extends into the driving shaft 7. The interior of the fixed cylinder 8 is hollow and communicates with the interior of the driving shaft 7; The fixed cylinder 8 is internally rotatably connected with a driving shaft 19 , and the driving shaft 19 is connected to the output shaft 18 via a bevel gear. When the output shaft 18 rotates, the driving shaft 19 can be driven to rotate by the bevel gear.

[0025] When the filling is almost mixed and the driving shaft 7 is still rotating, the second motor 4 is started, and the second motor 4 drives the output shaft 18 in the driving shaft 7 to rotate. The output shaft 18 drives the multiple driving shafts 19 to rotate under the action of the bevel gear.

[0026] A moving groove is provided in the extension cylinder 9, one end of the driving shaft 19 is located in the moving groove in the initial state, a moving cavity 20 is provided at the notch of the moving groove, a driving block 21 is slidably connected to the inner side wall of the moving cavity 20, and the driving block 21 is arranged in an arc shape on a side opposite to the moving groove; An outer wall of the driving shaft 19 is provided with an external thread 22, and an inner thread 23 is provided on the side of the driving block 21 opposite to the driving shaft 19. The inner thread 23 and the outer thread 22 are adapted to each other. When the scraper rod 17 is not in contact with the inner wall of the mixing drum 1, the inner thread 23 and the outer thread 22 are meshed with each other.

[0027] During the above-mentioned rotation of the driving shaft 19, since the sliding direction of the driving block 21 is perpendicular to the setting direction of the driving shaft 19, and the driving block 21 is in contact with the outer wall of the driving shaft 19 under the action of the reset spring 25, the rotation of the driving shaft 19 will move the extension cylinder 9 toward the outside of the fixed cylinder 8 under the action of the internal thread 23 and the external thread 22. At this time, the moving direction of the driving shaft 19 is toward the inner wall of the mixing drum 1, thereby also driving the scraper rod 17 to move toward the inner wall of the mixing drum 1.

[0028] Refer to the attached Figure 6A return spring 25 is provided between the push block 21 and the moving cavity 20, and a push rod 24 is inserted through the extension cylinder 9, one end of the push rod 24 is in the moving cavity 20, and the other end is outside the extension cylinder 9 and close to the scraper rod 17; The push rod 24 is connected to the push block 21 via a transmission rod 26. The movement of the push rod 24 drives the push block 21 to move toward the bottom of the moving cavity 20 via the transmission rod 26. A telescopic rod 27 is provided between the scraper rod 17 and the extension cylinder 9 . When the scraper rod 17 contacts the inner wall of the mixing drum 1 , the push rod 24 is pushed.

[0029] As described above, when the scraper rod 17 moves toward the inner wall of the mixing drum 1, it should be noted that the resistance of the filling to the scraper rod 17 is not enough to enable the scraper rod 17 to push the push rod 24. When the scraper rod 17 moves close to the inner wall of the mixing drum 1 and contacts the inner wall, the telescopic rod 27 will be compressed, and the distance between the extension cylinder 9 and the scraper rod 17 will also decrease until the scraper rod 17 and the push rod 24 are against each other. When the push rod 24 is pushed toward the fixed cylinder 8 under the action of the scraper rod 17, refer to the attached Figure 6 In the enlarged view in FIG. 1 , the push rod 24 moves the push block 21 under the action of the transmission rod 26, so that the reset spring 25 is compressed. At this time, the internal thread 23 and the external thread 22 are separated from each other. Even if the push shaft 19 continues to rotate, it will not continue to drive the extension cylinder 9 to move. At this time, the scraper rod 17 will be in a relatively stable position in contact with the inner wall of the mixing drum 1. The two can be closely attached without the operator's naked eye observation, and can adapt to mixing drums 1 of different sizes.

[0030] In summary, during the process of stirring the filling, the scraper rod 17 will not continuously stick to the inner wall of the mixing drum 1, but will only stick to the inner wall of the mixing drum 1 when the filling is about to be finished, thereby delaying the occurrence of a situation where the gap between the scraper rod 17 and the inner wall of the mixing drum 1 becomes larger due to the long-term sticking of the scraper rod 17 and the inner wall of the mixing drum 1. The service life of the stuffing mixing device is increased, and the efficiency of scraping the stuffing that sticks to the wall can also be improved.

[0031] Example 2 This embodiment is an improvement on the existing method of stirring the filling. During the process of stirring the filling by the stirring rod 12 and the stirring rod 10, the stirring rod 12 and the stirring rod 10 will swing to improve the stirring efficiency of the filling.

[0032] A mixing rod 12 is rotatably connected to the fixed cylinder 8 , and the mixing rod 12 can swing in the filling during the rotation of the driving shaft 7 .

[0033] The support frame 2 is fixedly connected with a guide disc 3, which is arranged on the outside of the driving shaft 7. A guide groove 15 is provided at the bottom of the guide disc 3, and the guide groove 15 is arranged in a wave shape along the setting direction of the guide disc 3. A reserved frame 16 is slidably connected in the guide groove 15, and the top end of the mixing rod 12 is slidably connected to the inner side wall of the reserved frame 16; The stirring rod 10 is provided with a sliding groove 13 , in which a sliding block 14 is slidably connected. The bottom end of the stirring rod 12 is rotationally connected to the sliding block 14 . The stirring rod 10 is rotationally connected to the driving shaft 7 via the rotating shaft 11 .

[0034] Refer to the attached Figure 2 -Attached Figure 4 When the fixed cylinder 8 rotates under the action of the driving shaft 7, the mixing rod 12 and the stirring rod 10 will be driven to rotate, and the top of the mixing rod 12 will move along the setting of the guide groove 15. Figure 3 The guide groove 15 is arranged in an annular wave-like manner, thereby causing the lateral distance of the reserved frame 16 to change repeatedly, and driving the mixing rod 12 to swing during the rotation process.

[0035] And refer to the attached Figure 4 When the top of the mixing rod 12 changes its displacement, the bottom of the mixing rod 12 also changes its distance, which causes the sliding block 14 to move in the sliding groove 13 synchronously, so that the mixing rod 10 can swing during the rotation.

[0036] Compared with the fixed stirring process in the prior art, the stirring method of the mixing rod 12 and the stirring rod 10 increases the stirring range of the filling and can better stir the filling.

[0037] A method for using a stuffing mixing device for reducing wall sticking comprises the following steps: ① Put the filling into the mixing drum 1, wherein the height of the filling is not higher than the height of the fixed cylinder 8; ② Then the first motor 5 is turned on, and the first motor 5 drives the driving shaft 7 to rotate. When the driving shaft 7 rotates, the filling is stirred by the stirring rod 10 and the mixing rod 12. In the process of stirring the filling by the stirring rod 10, the mixing rod 12 and the stirring rod 10 are made to swing through the action of the guide groove 15 to improve the stirring efficiency of the filling; ③ When the filling is about to be mixed but has not yet been completed, the second motor 4 will be turned on to make the scraper 17 stick to the inner wall of the mixing drum 1. At this time, the driving shaft 7 will continue to rotate to scrape the filling on the inner wall of the mixing drum 1 through the scraper 17, so as to reduce the occurrence of filling sticking to the wall.
