The second bevel gear 309 and the third bevel gear 310 are both meshed with the first bevel gear 308, and the second bevel gear 309 and the third bevel gear 310 are respectively The first bevel gear 308 is meshed with the second bevel gear 309, and the meshed connection between the second bevel gear 309 and the first bevel gear 308 causes the first bevel gear 308 to rotate. The meshed connection between the third bevel gear 310 and the first bevel gear 308 causes the third bevel gear 310 to rotate. Since the third bevel gear 310 and the second bevel gear 309 are respectively located on both sides of the first bevel gear 308, the rotation directions of the third bevel gear 310 and the second bevel gear 309 are opposite. The third bevel gear 310 drives the second sleeve 305 and the second stirring blade 306 to rotate in the opposite direction of the first stirring blade 303. When the raw materials are stirred, the shear force generated between the first stirring blade 303 and the second stirring blade 306 is greatly increased. Compared with the prior art, the stirring effect is significantly improved in the later stage of stirring. Reference Figures 1-8, a rotation direction switching mechanism is provided on the top of the mixing tank 1, and the rotation direction switching mechanism includes a fourth bevel gear 401, the fourth bevel gear 401 is fixedly sleeved on the surface of the drive shaft 301, and a spline sleeve 402 is provided on the top of the mixing tank 1, and the surface of the spline sleeve 402 is fixedly sleeved with a fifth bevel gear 403 and a sixth bevel gear 404, and the fifth bevel gear 403 and the sixth bevel gear 404 are respectively located on both sides of the fourth bevel gear 401, and a plurality of support legs 405 are fixedly installed on the top of the mixing tank 1, wherein a slide rail 406 is fixedly installed between two support legs 405, and the surface sliding sleeve of the slide rail 406 is provided with two slides 407, and the spline sleeve 402 is rotatably sleeved inside the slide 407, and a mounting plate 408 is fixedly installed on the top of the support leg 405, and the shape of the mounting plate 408 is set to a cross shape, and the fifth bevel gear 403 and the sixth bevel gear 404 are intermittently meshed with the fourth bevel gear 401 respectively, and by setting the rotation Direction switching mechanism, when the spline shaft 421 rotates, the meshing teeth of the spline shaft 421 and the meshing teeth of the spline sleeve 402 are engaged, so that the spline sleeve 402 rotates simultaneously. In the initial state, the fifth bevel gear 403 and the fourth bevel gear 401 are meshed, and the sixth bevel gear 404 and the fourth bevel gear 401 are not in contact. The fifth bevel gear 403 drives the fourth bevel gear 401 to rotate, thereby causing the drive shaft 301 to rotate. When the spline sleeve 402 slides, the sixth bevel gear 404 and the fourth bevel gear 401 are meshed, and the fifth bevel gear 403 and the fourth bevel gear 401 are not in contact, thereby changing the rotation direction of the fourth bevel gear 401. Through the intermittent reciprocating sliding of the spline sleeve 402, the fifth bevel gear 403 and the sixth bevel gear 404 intermittently mesh with the fourth bevel gear 401 in turn, thereby intermittently changing the rotation direction of the drive shaft 301, further increasing the shear force and improving the stirring effect; Reference Figures 1-8The bottom of the mounting plate 408 is rotatably mounted with a follower rod 409, and the surface of the follower rod 409 is fixedly sleeved with a driving gear 410. A driving tooth plate 411 is fixedly mounted between the two slides 407. A fixed rod 412 is fixedly mounted on the top of the mixing tank 1. The surface of the fixed rod 412 is rotatably sleeved with a fan-shaped plate 413. The fan-shaped plate 413 is slidably sleeved with an arc-shaped tooth plate 414. The arc-shaped tooth plate 414 and the driving tooth plate 411 are both engaged with the driving gear 410. The fan-shaped plate 412 is fixedly mounted with a fan-shaped plate 413. 13 is integrally formed with a drive plate 415, and a drive groove 416 is provided on the drive plate 415. An eccentric rod 417 is provided on the top of the drive plate 415. An eccentric shaft 418 is fixedly installed at the bottom of the eccentric rod 417. The eccentric shaft 418 is slidably sleeved inside the drive groove 416. A raised seat 419 is installed on the top of the mixing tank 1. A first motor 420 is installed on the top of the raised seat 419. The output end of the first motor 420 is equipped with a spline through a coupling. The spline sleeve 402 is slidably mounted on the surface of the spline shaft 421. By setting the driving gear 410, when the eccentric rod 417 rotates, the eccentric shaft 418 is driven to squeeze the inner wall of the driving groove 416, so that the driving plate 415 drives the sector plate 413 to swing back and forth. When the sector plate 413 swings back and forth, due to the friction between the arc-shaped tooth plate 414 and the driving gear 410, the two remain relatively stationary until the protrusions and arcs on both sides of the sector plate 413 are aligned. When the curved tooth plates 414 come into contact with each other, the curved tooth plates 414 are squeezed, driving the curved tooth plates 414 to move. The meshing connection between the curved tooth plates 414 and the driving gear 410 causes the driving gear 410 to intermittently reciprocate. The meshing connection between the driving gear 410 and the driving tooth plates 411 causes the slide 407 to intermittently reciprocate, thereby causing the fifth bevel gear 403 and the sixth bevel gear 404 to intermittently mesh with the fourth bevel gear 401 in turn. Reference Figures 1-8 The shape of the upper part and the shape of the lower part of the feed port 2 are set to be funnel-shaped with opposite expansion directions. The feed port 2 is set to be through-through from top to bottom. The top of the mixing tank 1 is provided with an intermittent feeding mechanism, which includes a reciprocating slide 501. The reciprocating slide 501 is slidably sleeved in the inner cavity of the feed port 2. The reciprocating slide 501 contacts the inner wall of the feed port 2. By setting the intermittent feeding mechanism, when the user pours the raw materials into the inside of the feed port 2, the reciprocating slide 501 slides back and forth inside the feed port 2. When the reciprocating slide 501 is When the slide 501 moves to the left, the reciprocating slide 501 no longer closes the feed port 2, allowing the raw materials to enter the mixing tank 1 through the feed port 2. When the reciprocating slide 501 moves to the right, the raw materials are blocked by the reciprocating slide 501 and accumulate on the top of the reciprocating slide 501. This is repeated, so that the raw materials will not continuously enter the mixing tank 1 through the feed port 2. While the raw materials are being fed, they are stirred by the first stirring blade 303 and the second stirring blade 306, so that the raw materials can be mixed faster. Reference Figures 1-8 , a second motor 502 is installed on the top of the mounting plate 408, a first connecting rod 503 is installed on the output end of the second motor 502, a transmission rod 504 is installed on the bottom of the first connecting rod 503, the bottom of the transmission rod 504 is connected to the top of the eccentric rod 417, a second connecting rod 505 is provided between the first connecting rod 503 and the reciprocating slide 501, one end of the second connecting rod 505 is rotatably sleeved inside the first connecting rod 503, and the other end of the second connecting rod 505 is rotatably sleeved on the surface of the reciprocating slide 501, a limiting block is provided on the surface of the feed port 2, and the reciprocating slide The plate 501 is slidably sleeved inside the limit block. By setting the first connecting rod 503 and the second connecting rod 505, the user starts the second motor 502 to drive the first connecting rod 503 to rotate. Since one end of the second connecting rod 505 is rotatably sleeved inside the first connecting rod 503, the other end of the second connecting rod 505 is rotatably sleeved on the surface of the reciprocating slide 501, the reciprocating slide 501 slides back and forth through the limiting cooperation of the limit block. At the same time, through the cooperation of the transmission rod 504, the first connecting rod 503 drives the eccentric rod 417 to rotate at the same time.

[0023] Combine Figures 1-8The working process of the anti-counterfeiting material preparation device is as follows: when in use, the first motor 420 is started to drive the spline shaft 421 to rotate, and the spline sleeve 402 rotates at the same time through the meshing between the meshing teeth of the spline shaft 421 and the meshing teeth of the spline sleeve 402. In the initial state, the fifth bevel gear 403 and the fourth bevel gear 401 are meshed, and the sixth bevel gear 404 and the fourth bevel gear 401 are not in contact. The fifth bevel gear 403 drives the fourth bevel gear 401 to rotate, thereby causing the rotating rod 301 to rotate, thereby driving the first sleeve 302 and the first stirring blade 303 to rotate. At the same time, the rotating rod 301 drives the second bevel gear 309 to rotate, and the meshing connection between the second bevel gear 309 and the first bevel gear 308 makes the first bevel gear 30 8 rotates, and the meshing connection between the third bevel gear 310 and the first bevel gear 308 causes the third bevel gear 310 to rotate. Since the third bevel gear 310 and the second bevel gear 309 are respectively located on both sides of the first bevel gear 308, the rotation directions of the third bevel gear 310 and the second bevel gear 309 are opposite. The third bevel gear 310 drives the second sleeve 305 and the second stirring blade 306 to rotate in the opposite direction of the first stirring blade 303. The user starts the second motor 502 to drive the first connecting rod 503 to rotate. Since one end of the second connecting rod 505 is rotatably sleeved inside the first connecting rod 503, and the other end of the second connecting rod 505 is rotatably sleeved on the surface of the reciprocating slide 501, the limiting cooperation of the limiting block is realized. When the reciprocating slide 501 moves to the left, the reciprocating slide 501 no longer closes the feed port 2, allowing the raw materials to enter the mixing tank 1 through the feed port 2. When the reciprocating slide 501 moves to the right, the raw materials are blocked by the reciprocating slide 501 and accumulated on the top of the reciprocating slide 501. This is repeated. At the same time, through the cooperation of the transmission rod 504, the first connecting rod 503 drives the eccentric rod 417 to rotate at the same time. When the eccentric rod 417 rotates, it drives the eccentric shaft 418 to squeeze the inner wall of the driving groove 416, so that the driving plate 415 drives the sector plate 413 to swing back and forth. When the sector plate 413 swings back and forth, due to the arc-shaped tooth plate 414 and the driving gear The friction force between 410 keeps the two relatively still until the protrusions on both sides of the sector plate 413 come into contact with the arc-shaped toothed plate 414, which squeezes the arc-shaped toothed plate 414 and drives the arc-shaped toothed plate 414 to move. The meshing connection between the arc-shaped toothed plate 414 and the driving gear 410 causes the driving gear 410 to intermittently reciprocate. The meshing connection between the driving gear 410 and the driving toothed plate 411 causes the slide 407 to intermittently reciprocate. When the spline sleeve 402 slides, the sixth bevel gear 404 and the fourth bevel gear 401 are meshed, and the fifth bevel gear 403 and the fourth bevel gear 401 are not in contact, thereby changing the rotation direction of the fourth bevel gear 401. Through the intermittent reciprocating sliding of the spline sleeve 402,The fifth bevel gear 403 and the sixth bevel gear 404 intermittently mesh with the fourth bevel gear 401 in turn, thereby intermittently changing the rotation direction of the rotating rod 301 and further increasing the shear force.

In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation.

10. A method for preparing an anti-counterfeiting material preparation device according to any one of claims 1 to 9, characterized in that: Here are the steps: S1. Raw material stirring: the raw material is put into the feed port (2), and the first motor (420) is started, so that the driving shaft (301) drives the first stirring blade (303) to rotate, and at the same time, through the cooperation of the first bevel gear (308), the rotating shell (304) is rotated, thereby driving the second stirring blade (306) to rotate, and because the second bevel gear (309) and the third bevel gear (310) are respectively located on both sides of the first bevel gear (308), the rotation directions of the first stirring blade (303) and the second stirring blade (306) are opposite, thereby increasing the shear force generated during the stirring process of the first stirring blade (303) and the second stirring blade (306); S2, intermittent reciprocating stirring: starting the second motor (502), causing the driving gear (410) to rotate reciprocatingly, driving the tooth plate (411) to move reciprocatingly, and the slide (407) driving the spline sleeve (402) to move reciprocatingly, causing the fifth bevel gear (403) and the sixth bevel gear (404) to engage with the fourth bevel gear (401) in turn, causing the rotation direction of the driving shaft (301) to change intermittently; S3. Intermittent feeding: When the second motor (502) is started, the first connecting rod (503) rotates at the same time, and the reciprocating slide (501) slides back and forth inside the feed port (2) through the cooperation of the second connecting rod (505). The raw materials accumulated on the top of the reciprocating slide (501) are squeezed by the inner wall of the feed port (2) and fall into the interior of the mixing tank (1) when the reciprocating slide (501) slides.
