It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

A combustion furnace 7 is provided at the bottom of the mixing tank 101, and a first mixing component 5 is movably provided inside the mixing tank 101. A rotating component 3 connected to the first mixing component 5 is provided between the mixing tank 101 and the outer bracket 202, a reciprocating swinging component 4 is provided between the mixing tank 101 and the rotating component 3, and a second mixing component 6 that cooperates with the first mixing component 5 is provided inside the mixing tank 101.

[0039] In this embodiment, the slurry and additives can be introduced through the cooperation of the feeding pipe 102 and the first electrically controlled valve 103, and the mixture can be discharged through the cooperation of the discharge pipe 104 and the second electrically controlled valve 105. The bottom of the mixing tank 101 can be heated by the combustion furnace 7 to meet the mixing temperature requirements of the slurry and additives, thereby avoiding the problem of uneven paper thickness or reduced strength caused by unstable slurry viscosity. The rotating component 3 drives the mixing tank 101 to swing back and forth in the support ring frame 201 by cooperating with the reciprocating swing component 4, so as to drive the slurry inside the mixing tank 101 to swing synchronously. When heating the bottom of the mixing tank 101, it is convenient to uniformly heat the bottom of the mixing tank 101, which is conducive to the rapid and uniform mixing of the slurry and the additives. The rotating component 3 drives the first mixing component 5 and the second mixing component 6 to rotate to perform multi-stage stirring on the slurry and the additives in the mixing tank 101. At the same time, the lumps or overlong raw materials in the slurry can be cut, which is conducive to the efficient and uniform mixing of the slurry and the additives, and can effectively avoid the color difference or performance fluctuation on the surface of the paper, thereby improving the use effect of the subsequent household paper. It has the effects of uniform heating, reciprocating swing, multi-stage stirring, efficient and uniform mixing, reliable structure, convenient operation and simple and practical use.

[0040] There are two combustion furnaces 7 and they are symmetrically distributed about the discharge pipe 104 , so as to facilitate rapid heating of the slurry inside the mixing tank 101 .

[0041] In one embodiment of the present invention, see Figure 1-Figure 3 The rotating assembly 3 includes a rotating rod 305 rotatably arranged inside the mixing tank 101, the rotating rod 305 is connected to the first mixing assembly 5, the two ends of the rotating rod 305 respectively pass through the corresponding ends of the mixing tank 101, the end of the rotating rod 305 is rotatably matched with the side bracket 306 arranged on the outer wall of the support ring frame 201, and one end of the rotating rod 305 is provided with a driven pulley 304, and a rotating motor 301 is installed on the outer bracket 202. The output end of the rotating motor 301 is connected to a driving pulley 302, and a transmission belt 303 is connected between the driving pulley 302 and the driven pulley 304.

[0042] In this embodiment, the rotating motor 301 drives the active pulley 302 to rotate, and the active pulley 302 drives the driven pulley 304 to rotate synchronously by cooperating with the transmission belt 303. The driven pulley 304 drives the first mixing component 5 and the second mixing component 6 to rotate and move in the mixing tank 101 by driving the rotating rod 305 to rotate synchronously, which can quickly and evenly mix the slurry and additives inside the mixing tank 101, and effectively avoid color difference or performance fluctuation on the paper surface.

[0043] In one embodiment of the present invention, see Figure 1-Figure 7 The first mixing assembly 5 includes a fixed cylinder 501 symmetrically and movably sleeved on the outside of the rotating rod 305, the ends of the fixed cylinders 501 away from each other are fixedly connected to the inner wall of the end of the mixing tank 101, and the ends of the fixed cylinders 501 close to each other are provided with a reciprocating spiral slide 502, a rotating plate 503 located in the middle of the mixing tank 101 is installed on the rotating rod 305, a plurality of first stirring paddles 504 are installed circumferentially on the rotating plate 503, a cross bar 505 is installed on the rotating plate 503 between two adjacent first stirring paddles 504, and the end of the cross bar 505 is connected to the inner wall of the end of the mixing tank 101 A second scraper 511 is rotatably fitted, and a rotating tank 506 is movably sleeved on each of the two fixed cylinders 501. The rotating tank 506 slides with the corresponding reciprocating spiral slide 502. A plurality of through holes 507 are circumferentially distributed on the circumferential side wall of the rotating tank 506. The cross bar 505 passes through the rotating tank 506 and slides with the rotating tank 506. A plurality of feed ports 508 are circumferentially distributed on the rotating tank 506. A discharge port 510 is provided on the rotating tank 506 between two adjacent feed ports 508. A first scraper 509 corresponding to the feed port 508 is provided on the rotating tank 506.

[0044] In this embodiment, the rotating motor 301 drives the active pulley 302 to rotate, and the active pulley 302 drives the driven pulley 304 to rotate synchronously by cooperating with the transmission belt 303. The driven pulley 304 drives the rotating plate 503 to rotate synchronously by driving the rotating rod 305 to rotate synchronously. The rotating plate 503 stirs the slurry and additives in the middle of the mixing tank 101 by driving the first stirring paddle 504 to rotate synchronously. At the same time, the rotating plate 503 drives the rotating tank 506 to rotate synchronously by being connected to the cross bar 505 and the cross bar 505 slidingly cooperating with the rotating tank 506. The rotating tank 506 can scrape off the slurry adhering to the inner wall of the circumference of the mixing tank 101 by driving the first scraper 509 to rotate synchronously, so as to facilitate the comprehensive mixing of the slurry and additives and prevent some slurry adhering to the inner wall of the circumference of the mixing tank 101 from being mixed. The slurry in the mixing tank 101 enters the rotating tank 506 through the feed port 508 and the through hole 507, and the slurry mixed in the rotating tank 506 is discharged through the through hole 507 and the discharge port 510. The introduction and discharge of the slurry are carried out simultaneously, which is convenient for fully mixing the slurry and the additive. At the same time, since the position of the fixed cylinder 501 is fixed and the rotating tank 506 is slidably matched with the reciprocating spiral chute 502, the rotating tank 506 is driven to reciprocate and rotate along the axis of the fixed cylinder 501 by slidingly matching with the reciprocating spiral chute 502 and slidingly matching with the cross bar 505, so that the two rotating tanks 506 move closer to or away from each other while rotating, which is convenient for efficient mixing of the slurry and the additive, and can avoid fixed unidirectional stirring of the slurry and the additive in the mixing tank 101.

[0045] In addition, the crossbar 505 is connected to the second scraper 511 to rotate and scrape off the slurry adhering to the inner wall of the end of the mixing tank 101, thereby improving the utilization rate of the slurry and preventing the slurry from accumulating on the inner wall of the end of the mixing tank 101 and affecting the quality of subsequent slurry mixing.

[0046] Among them, the number of the feed ports 508 is consistent with the number of the discharge ports 510, and the number of the feed ports 508 is at least three. The cross bar 505 corresponds to the discharge port 510, which can effectively avoid blocking the introduction of the slurry. At the same time, it is also convenient for the second mixing component 6 to stir the slurry to be discharged. The rotating plate 503 is configured as a multi-protrusion plate and is provided with at least three protrusions in its circumference. The number of protrusions on the rotating plate 503 is consistent with the number of cross bars 505.

[0047] In one embodiment of the present invention, see Figure 1-Figure 5The second mixing assembly 6 includes several unidirectional spiral grooves 601 spirally arranged at the end of the cross bar 505, and several rotating cylinders 602 are circumferentially distributed inside the rotating tank 506. The two ends of the rotating cylinder 602 are rotatably matched with the inner wall of the rotating tank 506. The rotating cylinder 602 is movably sleeved on the outside of the cross bar 505 and slidingly matched with the unidirectional spiral groove 601. Several second stirring paddles 603 are spirally distributed on the rotating cylinder 602, and several crushing knives 604 are spirally distributed on the rotating cylinder 602. The second stirring paddles 603 and the crushing knives 604 correspond to each other.

[0048] In this embodiment, the rotating motor 301 drives the active pulley 302 to rotate, and the active pulley 302 drives the driven pulley 304 to rotate synchronously by cooperating with the transmission belt 303, and the driven pulley 304 drives the rotating plate 503 to rotate synchronously by driving the rotating rod 305 to rotate synchronously, and the rotating plate 503 stirs the slurry and additives in the middle of the mixing tank 101 by driving the first stirring paddle 504 to rotate synchronously. At the same time, the rotating plate 503 drives the rotating tank 506 to rotate synchronously by being connected to the cross bar 505 and the cross bar 505 slidingly cooperating with the rotating tank 506. Since the fixed cylinder 501 is fixed in position and the rotating tank 506 slides with the reciprocating spiral chute 502, the rotating tank 506 drives the rotating tank 506 along the fixed cylinder 501 by slidingly cooperating with the reciprocating spiral chute 502 and the rotating tank 506 slidingly cooperating with the cross bar 505. The axis of the fixed drum 501 reciprocates and rotates, and the rotating tank 506 drives the rotating drum 602 to reciprocate along the axial direction of the cross bar 505. The rotating drum 602 drives the plurality of second stirring paddles 603 and the crushing blades 604 to rotate by sliding with the unidirectional spiral groove 601 and rotating with the rotating drum 602 and the rotating tank 506. The rotation of the plurality of second stirring paddles 603 can stir the slurry and additives inside the rotating tank 506 for a second time. At the same time, the slurry to be discharged from the discharge port 510 is stirred again to improve the mixing effect of the slurry and additives. The rotation of the plurality of crushing blades 604 can cut the agglomerated or overlong raw materials in the slurry, which is conducive to efficient and uniform mixing of the slurry and additives, and can effectively avoid color difference or performance fluctuation on the paper surface, thereby improving the use effect of subsequent household paper.

[0049] The number of the rotating cylinders 602 located inside a single rotating tank 506 is consistent with the number of the cross bars 505 .

[0050] In one embodiment of the present invention, see Figure 1-Figure 3The reciprocating swing component 4 includes a first fixing nail 401 installed on one end of the support ring frame 201 away from each other and a second fixing nail 402 installed on the end of the mixing tank 101. The first fixing nail 401 and the second fixing nail 402 are respectively located on both sides of the rotating rod 305. A movable frame 404 is movably provided at the end of the mixing tank 101. One end of the movable frame 404 is rotatably engaged with the second fixing nail 402, and the other end of the movable frame 404 is connected to a movable slot plate 405, which is slidably engaged with the first fixing nail 401. A rotating cam 403 located on the inner side of the movable frame 404 is installed on the rotating rod 305, and the rotating cam 403 is movably in contact with the inner wall of the movable frame 404.

[0051] In this embodiment, in the initial state, the farthest end of the rotating cam 403 is located at the bottom, and the closest end of the rotating cam 403 is located at the top. The line connecting the closest end of the rotating cam 403 to the farthest end of the rotating cam 403 is collinear with the line connecting the first fixing pin 401 to the second fixing pin 402. The first fixing pin 401 is located in the middle of the movable slot plate 405.

[0052] The rotating motor 301 drives the driving pulley 302 to rotate. The driving pulley 302 drives the driven pulley 304 to rotate synchronously by cooperating with the transmission belt 303. The driven pulley 304 drives the rotating cam 403 to rotate by driving the rotating rod 305 to rotate synchronously.

[0053] In the process of the farthest end of the rotating cam 403 rotating upward, the rotating cam 403 drives the second fixing nail 402 to rotate upward to one side by contacting the inner wall of the movable frame 404, the movable slot plate 405 slidingly cooperating with the first fixing nail 401, the movable frame 404 rotating cooperating with the second fixing nail 402, and the mixing tank 101 rotating cooperating with the support ring frame 201. When the line between the nearest end of the rotating cam 403 and the farthest end of the rotating cam 403 and the line between the first fixing nail 401 and the second fixing nail 402 are in a vertical state, at this time, the mixing tank 101 reaches the farthest end. At a large swing angle, when the farthest end of the rotating cam 403 continues to rotate upward, the rotating cam 403 drives the second fixing nail 402 to rotate downward by contacting the inner wall of the movable frame 404, the movable slot plate 405 slidingly cooperating with the first fixing nail 401, the movable frame 404 rotatingly cooperating with the second fixing nail 402, and the mixing tank 101 rotatingly cooperating with the support ring frame 201. When the line between the nearest end of the rotating cam 403 and the farthest end of the rotating cam 403 is collinear with the line between the first fixing nail 401 and the second fixing nail 402, the mixing tank 101 returns to the initial angle;

[0054] During the downward rotation of the farthest end of the rotating cam 403, the rotating cam 403 drives the second fixing nail 402 to rotate upward to the other side by contacting the inner wall of the movable frame 404, sliding cooperation of the movable slot plate 405 and the first fixing nail 401, rotation cooperation of the movable frame 404 and the second fixing nail 402, and rotation cooperation of the mixing tank 101 and the supporting ring frame 201. When the line between the nearest end of the rotating cam 403 and the farthest end of the rotating cam 403 and the line between the first fixing nail 401 and the second fixing nail 402 are in a vertical state, at this time, the mixing tank 101 reaches At the maximum swing angle, when the farthest end of the rotating cam 403 continues to rotate downward, the rotating cam 403 drives the second fixing nail 402 to rotate downward by contacting the inner wall of the movable frame 404, the sliding cooperation of the movable slot plate 405 and the first fixing nail 401, the rotational cooperation of the movable frame 404 and the second fixing nail 402, and the rotational cooperation of the mixing tank 101 and the supporting ring frame 201. When the line between the nearest end of the rotating cam 403 and the farthest end of the rotating cam 403 is collinear with the line between the first fixing nail 401 and the second fixing nail 402, the mixing tank 101 returns to the initial angle;

[0055] The continuous rotation of the rotating cam 403 can achieve continuous reciprocating swing of the mixing tank 101, which can drive the slurry and additives inside the mixing tank 101 to swing synchronously. At the same time, it is convenient to evenly heat the bottom of the mixing tank 101, so as to maintain the viscosity of the slurry and avoid the problem of uneven thickness or reduced strength of paper caused by unstable slurry viscosity.

[0056] The distance between the two side walls inside the movable frame 404 that contact the outer edge of the rotating cam 403 is not less than the distance between the farthest end of the rotating cam 403 and the nearest end of the rotating cam 403, which can ensure that the rotating cam 403 rotates in the movable frame 404.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
