[0041] The technical solutions of the present application are further illustrated below in conjunction with the drawings and through specific embodiments.

[0042] As Figure 1As shown, the embodiment of the present application provides a system for improving the homogenization of roll-pressed sheet, which comprises a first mixer 1, an extruder 2, a cutting assembly 3, a second mixer 4, a roll-pressing assembly 5, and a dryer 6. During the preparation of the roll-pressed sheet, the dry-wet mixed raw materials enter through the inlet end of the first mixer 1, the first mixer 1 performs the stirring action, and the raw materials are first strongly mixed in the first mixer 1 and then kneaded into a ball and output through the outlet end of the first mixer 1 and enter the extruder 2 through the inlet end of the extruder 2. The outlet end of the extruder 2 is provided with a sieve plate 211, the sieve plate 211 is provided with a plurality of sieve holes 2111, the extruder 2 extrudes the first strongly mixed raw materials and outputs them in the form of strips through the sieve holes 2111 of the sieve plate 211, the curled or agglomerated plant fibers in the raw materials can be straightened during the extrusion process, effectively reducing the agglomeration of plant fibers in the raw materials; the shape of the sieve holes 2111 can be circular, triangular, rectangular, or trapezoidal, etc., which is not limited here; preferably, the sieve holes 2111 are circular, and the diameter is set to be between 1-10mm, specifically, the diameter of the sieve holes 2111 can be set to 1mm, 1.5mm, 3mm, or 10mm, etc., which can be set according to actual needs; the strip-shaped raw materials output through the sieve plate 211 are cut into granules by the cutting assembly 3 and enter the second mixer 4 through the inlet end of the second mixer 4, the length of the plant fibers in the cut raw materials is reduced, further reducing the agglomeration of plant fibers in the raw materials; the second mixer 4 is also used to perform the stirring action, and the second mixer 4 second strongly mixes the granular raw materials and kneads them into a ball, which is output through the outlet end of the second mixer 4 to the conveying belt 8; the conveying belt 8 drives the second strongly mixed and kneaded raw materials to enter from the inlet end of the roll-pressing assembly 5, and the roll-pressing assembly 5 rolls the raw materials on the conveying belt 8 into a sheet; the dryer 6 is located at the outlet end of the roll-pressing assembly 5, and the conveying belt 8 continues to drive the sheet to move into the dryer 6 for drying.

[0043] The raw materials are first strongly mixed and stirred by the first mixer 1, then extruded into strips by the extruder 2, cut into granules by the cutting assembly 3, and then transported to the second mixer 4 for second strong mixing and stirring and kneading into a ball, and then rolled into a sheet by the roll-pressing assembly 5, and finally dried by the dryer 6. The sheet obtained by the system for improving the homogenization of roll-pressed sheet has significantly improved uniformity of the internal raw materials, thereby improving the strength and quality of the sheet.

[0044] The dry-wet mixed raw materials include tobacco powder, adhesive, plant fiber, humectant, and water, etc., wherein the proportion of water in the raw materials is 20%-60%.

[0045] In order to further improve the uniformity of the raw materials in the sheet, the sheet homogenization system of the roll pressing method further comprises a mixing tank 7, and the strip-shaped raw materials cut by the cutting assembly 3 first enter the mixing tank 7 through the inlet end of the mixing tank 7, and then the granular raw materials are output to the second mixer 4 through the outlet end of the mixing tank 7 after being uniformly mixed by the mixing tank 7. After the granular raw materials enter the mixing tank 7, the mixing tank 7 can reorder the relative positions of the granular raw materials, for example, moving the granular raw materials on the left side of the mixing tank 7 to the right side of the mixing tank 7, and moving the granular raw materials on the right side of the mixing tank 7 to the left side of the mixing tank 7.

[0046] The mixing tank 7 comprises a mixing tank frame 71, a mixing motor, and a plurality of stirring paddles 72. The plurality of stirring paddles 72 are spaced and staggered on the inner circumferential surface of the mixing tank frame 71 along the axial direction of the mixing tank frame 71. The stirring paddles 72 can rotate around their axes, and the mixing motor can drive the mixing tank frame 71 to rotate around its axis. Referring to Figure 1 , three stirring paddles 72 are provided, one on the left side of the mixing tank frame 71, one in the middle of the mixing tank frame 71, and one on the right side of the mixing tank frame 71. The three stirring paddles 72 are staggered. After the granular raw materials enter the mixing tank frame 71, the mixing tank frame 71 revolves around its axis, and the three stirring paddles 72 rotate around their own axes. When the mixing tank frame 71 revolves, the left stirring paddle 72 stirs the granular raw materials to move to the middle of the mixing tank frame 71, the right stirring paddle 72 stirs the granular raw materials to move to the middle of the mixing tank frame 71, and the middle stirring paddle 72 stirs the granular raw materials to move to the left and right sides, so that the relative positions of the granular raw materials change and the mixing is more uniform. The stirring paddles 72 can also be provided in six, wherein two stirring paddles 72 are symmetrically provided as a first group and located on the left side of the mixing tank frame 71, two stirring paddles 72 are symmetrically provided as a second group and located in the middle of the mixing tank frame 71, and two stirring paddles 72 are symmetrically provided as a third group and located on the right side of the mixing tank frame 71. The six stirring paddles 72 are staggered.

[0047] The number of stirring paddles 72 is determined according to the length of the mixing tank frame 71. The number of stirring paddles 72 can also be two, four, five, seven, or more, which is not limited here.

[0048] Further, in order to make the mixing tank frame 71 drive the granular raw materials to rise and then fall when rotating, referring to Figure 1 and combining with Figure 3The inner circumferential surface of the mixing tank frame 71 is also provided with a plurality of baffle plates 711, which are arranged at intervals along the axial direction of the mixing tank frame 71, i.e., uniformly distributed from the left side to the right side of the mixing tank frame 71, and each group of baffle plates 711 includes a plurality of baffle plates 711, which are uniformly distributed along the circumference of the inner circumferential surface of the mixing tank frame 71. When the mixing tank 7 rotates, the baffle plates 711 can drive the granular raw materials to rise for a distance and then fall, at which time the stirring paddles 72 can stir the falling granular raw materials when they rotate around their own axes, so as to make the mixing more uniform.

[0049] Preferably, the baffle plates 711 are inclinedly arranged on the inner circumferential surface of the mixing tank frame 71, i.e., the baffle plates 711 are arranged at a non-90° angle with the tangent line at that position of the mixing tank frame 71, so as to make it easier to drive the granular raw materials to rise.

[0050] In this embodiment, the mixing tank frame 71 is arranged to be inclined, so that the inlet end of the mixing tank frame 71 is higher than the outlet end of the mixing tank frame 71, to facilitate the output of the granular raw materials; in addition, the outlet end of the mixing tank frame 71 is also provided with a rapid discharge plate, and when the mixing tank frame 71 revolves around its axis, the granular raw materials can be output along the rapid discharge plate. Optionally, the inclination angle between the axis of the mixing tank frame 71 and the horizontal line is arranged to be between 5°-30°, and can be specifically arranged to be 5°, 15° or 30°.

[0051] Continuing to refer to Figure 1 The extruder 2 includes an extruder frame 21, an extruder shaft 22 and an extruder motor, the outer circumferential surface of the extruder shaft 22 is provided with a spiral shaft shoulder 221, the extruder shaft 22 is rotationally arranged in the extruder frame 21, a screen plate 211 is fixedly arranged at the outlet end of the extruder frame 21, and the extruder motor can drive the extruder shaft 22 to rotate. The first strongly mixed raw materials are kneaded into groups and enter the extruder frame 21 through the inlet end of the extruder frame 21, and when the extruder motor drives the extruder shaft 22 to rotate, the spiral shaft shoulder 221 can drive the raw materials in the extruder frame 21 to be output through the screen holes 2111 of the screen plate 211. This structure can extrude the group-shaped raw materials into strip-shaped output, so as to straighten the curled or agglomerated plant fibers in the raw materials during the extrusion process, effectively reducing the agglomeration of the raw materials.

[0052] Referring to Figure 1 and Figure 2, the cutting assembly 3 comprises a cutter holder 31, a cutting knife 32 and a cutting motor, the cutting knife 32 is fixedly arranged on the cutter holder 31, the cutting knife 32 is parallel to the sieve plate 211, and the cutting knife 32 is arranged close to the sieve plate 211, so that the raw material can be cut off by the cutting knife 32 after being output through the sieve plate 211, and automatic breaking due to gravity of the raw material itself can be avoided. It can be understood that the rotating speed of the cutting knife 32 and the rotating speed of the extrusion shaft 22 in the extruder 2 can determine the length of the granular raw material. Alternatively, the length of the granular raw material is 1-50mm; specifically, the length of the granular raw material can be set to 1mm, 1.5mm, 10mm or 50mm, and the rotating speed of the cutting knife 32 or the rotating speed of the extrusion shaft 22 can be adjusted according to actual requirements.

[0053] Alternatively, the cutting knife 32 is provided in plurality, the plurality of cutting knives 32 are uniformly distributed on the cutter holder 31 in the circumferential direction of the cutter holder 31, and the cutting knife 32 is provided in plurality, which can effectively reduce the rotating speed of the cutter holder 31 and make the structure more reasonable. Preferably, the number of the cutting knife 32 can be set to 3-6.

[0054] Alternatively, the cutting knife 32 is fixedly arranged on the cutter holder 31 through a positioning pin 321 and a fixing screw 322, the cutting knife 32 is convenient to install and accurate in positioning.

[0055] Alternatively, the cutter holder 31 is provided with a limiting groove, the cutting knife 32 is embedded in the limiting groove and installed on the cutter holder 31 through the positioning pin 321 and the fixing screw 322. In this structure, the limiting groove not only plays a positioning role, but also can bear a certain pressure during the rotation of the cutting knife 32, so that the cutting knife 32 is more convenient to install and replace and more stable in operation.

[0056] Continuing to refer to Figure 1 , the first mixer 1 comprises a first mixing holder 11, a first mixing shaft 12, a plurality of first mixing blades 13 and a first mixing motor, the plurality of first mixing blades 13 are spaced apart and welded to the outer periphery of the first mixing shaft 12 along the axial direction of the first mixing shaft 12, the first mixing shaft 12 is rotatably arranged on the first mixing holder 11, and the first mixing motor can drive the first mixing shaft 12 to rotate. When the first mixing shaft 12 rotates, the plurality of first mixing blades 13 can first strongly mix and knead the raw material into a ball.

[0057] The plurality of first mixing blades 13 are provided in two groups, and the two groups of first mixing blades 13 are symmetrically arranged with the axis of the first mixing shaft 12 as the center line. The first mixing blade 13 can also be provided in an integral annular blade structure and be sleeved and welded to the outer periphery of the first mixing shaft 12.

[0058] The second stirring machine 4 comprises a second stirring frame 41, a second stirring shaft 42, a plurality of second stirring blades 43, and a second stirring motor. The second stirring blades 43 are spaced and welded to the outer circumferential surface of the second stirring shaft 42 along the axial direction of the second stirring shaft 42. The second stirring shaft 42 is rotatably arranged in the second stirring frame 41. The second stirring motor is capable of driving the second stirring shaft 42 to rotate. When the second stirring shaft 42 rotates, the plurality of second stirring blades 43 perform a second strong stirring and kneading on the raw materials. The structure of the second stirring blades 43 is the same as that of the first stirring blades 13, which will not be described here.

[0059] It can be understood that the first stirring frame 11, the extrusion frame 21, the mixing tank frame 71, and the second stirring frame 41 are all hollow structures.

[0060] Preferably, the spacing between adjacent second stirring blades 43 gradually decreases from the inlet end of the second stirring frame 41 to the outlet end of the second stirring frame 41. In this structure, the spacing between adjacent second stirring blades 43 at the inlet end of the second stirring frame 41 is greater than the spacing between adjacent second stirring blades 43 at the outlet end of the second stirring frame 41. This is beneficial to generating a certain pressure on the raw materials at the outlet end of the second stirring frame 41, so that the granular raw materials are uniformly stirred and kneaded into a group and then output.

[0061] Preferably, the outlet end of the second stirring frame 41 is provided with a narrow square outlet, the length dimension is greater than the width dimension, and the length dimension of the square outlet matches the width of the sheet. The length dimension is preferably 200-2000 mm, and the width dimension is preferably 3-100 mm. When the stirring reaches a predetermined time or a predetermined degree, the raw materials are extruded from the outlet end of the second stirring frame 41, and the raw materials are pre-shaped and laid on the conveying belt 8. The conveying belt 8 rolls in the set direction under the joint action of the driving roller 81 and the driven roller 82 to output the sheet.

[0062] The roller pressing assembly 5 comprises three groups of pressing rollers 51. Each group of pressing rollers 51 comprises an upper roller 511 and a lower roller 512 arranged in a one-to-one correspondence. The three groups of pressing rollers 51 are arranged in a spaced manner along the rolling direction of the conveying belt 8. The lower roller 512 abuts against the inner side of the conveying belt 8. The upper roller 511 is located above the conveying belt 8 and has a set gap with the outer side of the conveying belt 8. Along the rolling direction of the conveying belt 8, the three upper rollers 511 have gradually decreasing set gaps with the outer side of the conveying belt 8. When the raw materials that have been subjected to a second strong mixing and kneading are output onto the conveying belt 8 through the outlet end of the second stirring frame 41, they are sequentially pressed into sheets of a predetermined thickness by the three groups of pressing rollers 51. Further, the upper roller 511 can move up and down in the vertical direction to adjust the gap between the upper roller 511 and the conveying belt 8, so that the gap reaches the set gap.

[0063] The sheet is dried and shaped in the drying channel of the drying machine 6 when it is output by the conveying belt 8, and the spade knife 83 separates the sheet from the conveying belt 8 and enters the output roller 9 for output.
