Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and more specifically, to a segmented, fixed-length sheet slitting device. Background Technology

[0002] Heated cigarettes are favored by consumers due to their lower harm and taste, which is similar to traditional cigarettes, and the market size is expanding daily. The processing technology of reconstituted tobacco leaves, the main raw material used in heated cigarettes, has also been further improved and developed, such as new roll pressing methods, dry papermaking sheet processing, thick pulp papermaking composite methods, and new thick pulp sheet processing, which have promoted the improvement of heated cigarette quality.

[0003] The reconstituted tobacco used in heated cigarettes is generally made from modified papermaking, slurry processing, and roll pressing sheets. The sheet accounts for 50%-100% of the composition. Due to the addition of a large amount of misting agents such as propylene glycol and glycerol, the sheet has high surface viscosity and is easy to absorb moisture. It is basically not feasible to use a separate shredding process, especially for roll pressing and slurry processing sheets used to process disordered heated cigarettes. Due to their low strength, easy breakage, easy adhesion, and difficulty in loosening, the reconstituted tobacco used in heated cigarettes is generally made into shreds before being blended, flavored, and rolled, or it is directly flavored and rolled.

[0004] Currently, the tobacco industry's equipment for shredding reconstituted tobacco leaves mostly employs two sets of shredding blades, first performing cross-cutting followed by longitudinal cutting, or vice versa. The shredded tobacco is of fixed length and width, and the equipment used is relatively complex. Furthermore, shredding reconstituted tobacco sheets into fixed lengths and widths results in poor adaptability during rolling, leading to inconsistent rolling quality.

[0005] Therefore, how to provide a regional fixed-length thin-sheet slitting device has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] One objective of this invention is to provide a new technical solution for a segmented, fixed-length thin-sheet slitting device.

[0007] According to a first aspect of the present invention, a segmented fixed-length thin sheet slitting device is provided, comprising: a housing, wherein an mounting cavity is provided within the housing;

[0008] A shredding assembly includes a shredding roller and a support roller, the shredding roller and the support roller being arranged parallel to each other and respectively fixed within the mounting cavity; the shredding roller includes multiple shredding sleeves, multiple longitudinal thin cutters, and a fixed shaft, the shredding sleeves and the longitudinal thin cutters being sleeved on the fixed shaft, and at least two shredding sleeves fixing one longitudinal thin cutter; the outer peripheral wall of the shredding sleeve is provided with a transverse shredding blade extending axially along the shredding sleeve;

[0009] A tobacco receiving box, which is disposed at the bottom of the mounting cavity, is used to receive tobacco shreds;

[0010] A fixing component is provided for fixing the cutting roller and the support roller.

[0011] Optionally, an annular knife-avoiding groove is provided on the outer peripheral wall of the support roller. The annular knife-avoiding groove is evenly spaced along the axial direction of the support roller, and the area between two adjacent annular knife-avoiding grooves is a smooth area.

[0012] Optionally, the shredding assembly further includes an arc-shaped guide plate, which is fixed to the housing and used to limit the reconstituted tobacco sheet. The arc-shaped guide plate corresponds to the smooth area, and the arc-shaped guide plate and the outer peripheral wall of the support roller form a reconstituted tobacco sheet conveying channel.

[0013] Optionally, the arc-shaped guide plate is provided with a plurality of ventilation holes and grooves, the first end of the arc-shaped guide plate is connected to the housing, and the grooves are evenly arranged at the second end of the arc-shaped guide plate and are arranged opposite to the longitudinal thin cutter.

[0014] Optionally, the shredding assembly further includes locking sleeves disposed at both ends of the shredding roller.

[0015] Optionally, the housing has corresponding first connecting holes on both sides, and the fixing component includes a first mounting bearing. The inner peripheral wall of the first mounting bearing is connected to both ends of the support roller, and the outer peripheral wall of the first mounting bearing is connected to the first mounting hole.

[0016] Optionally, the housing is provided with second connecting holes on both sides, and the fixing component includes a second mounting bearing. The inner peripheral wall of the second mounting bearing is connected to both ends of the fixing shaft, and the outer peripheral wall of the second mounting bearing is connected to the second mounting hole.

[0017] Optionally, the diameter of the second connecting hole is larger than the outer diameter of the second mounting bearing;

[0018] The segmented fixed-length thin filament slitting device further includes an adjustment component, which includes a first adjustment handle and a second adjustment handle. The first adjustment handle and the second adjustment handle are respectively connected to the outer peripheral wall of the second mounting bearing and are used to move the filament cutting roller to adjust the distance between the filament cutting roller and the support roller.

[0019] Optionally, the fixing assembly further includes a fixing nut, by which the slicing roller and the support roller are fixed to the housing.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention features a cutting roller and a support roller arranged parallel to each other and fixed within an installation cavity. The cutting roller includes multiple cutting sleeves, multiple longitudinal thin cutters, and a fixed shaft. The cutting sleeves and longitudinal thin cutters are all fitted onto the fixed shaft, with at least two cutting sleeves fixing one longitudinal thin cutter. A transverse cutting cutter extends axially along the outer periphery of the cutting sleeve. A receiving box is located at the bottom of the installation cavity and is secured to the cutting roller and support roller by a fixing assembly. In use, the operator first adjusts the number of cutting sleeves and longitudinal thin cutters according to the required tobacco length for rolling. Then, the cutting roller and support roller are fixed using the fixing assembly. The reconstituted tobacco sheet is then cut by the longitudinal thin cutter and the transverse thin cutter, resulting in tobacco of the required size, which is collected in the receiving box. The structure is simple, easy to install, and provides better adaptability for tobacco rolling, meeting the needs of the operator.

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0032] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] like Figures 1 to 6 As shown, this embodiment of the invention provides a segmented fixed-length thin-sheet slitting device, including: a housing 1, a slitting assembly, a slitting box 4, and a fixing assembly 6.

[0036] The housing 1 has an installation cavity (not shown in the figure), the shredder assembly and the receiving box 4 are installed in the installation cavity, and the top of the housing 1 is open so that the reconstituted tobacco sheet 101 is put into the shredder assembly through the opening at the top of the housing 1 and then cut into tobacco shreds by the shredder assembly.

[0037] The shredding assembly includes a shredding roller 3 and a support roller 2. The shredding roller 3 and the support roller 2 are arranged parallel to each other and are fixed in the mounting cavity. There is a certain gap between the shredding roller 3 and the support roller 2. The support roller 2 guides the reconstituted tobacco sheet 101 into the gap between the shredding roller 3 and the support roller 2, so that the shredding roller 3 cuts the reconstituted tobacco sheet 101.

[0038] The slicing roller 3 includes multiple slicing sleeves 32, multiple longitudinal thin cutters 33, and a fixed shaft 31. Both the slicing sleeves 32 and the longitudinal thin cutters 33 are sleeved on the fixed shaft 31, and at least two slicing sleeves 32 fix one longitudinal thin cutter 33. A transverse slicing cutter 321 extending axially along the outer peripheral wall of the slicing sleeve 32 is provided. Specifically, both ends of the fixed shaft 31 are fixed to the housing 1 and rotatably connected to it. The outer diameter of the longitudinal thin cutter 33 is at least 1.50 mm larger than the outer diameter of the transverse slicing cutter 321. In this embodiment, the outer diameter of the longitudinal thin cutter 33 is 5 mm larger than the outer diameter of the transverse slicing cutter 321. The thickness of the longitudinal thin cutter 33 is between 0.5 mm and 1.0 mm. In this embodiment, the thickness of the longitudinal thin cutter 33 is 0.8 mm. This design gives the longitudinal thin cutter 33 both good rigidity and good toughness.

[0039] The length of the cut tobacco shreds can be adjusted by changing the number of cutting sleeves 32 and longitudinal thin cutters 33. It should be noted that the width of the cutting sleeves 32 can be modularly configured, and the width can be determined according to the length of the tobacco shreds, generally between 10mm and 30mm. In this embodiment, the width of the cutting sleeves 32 is 10mm, which is beneficial for cutting tobacco shreds of different lengths. One longitudinal thin cutter 33 can be fixed to two adjacent cutting sleeves 32, or four cutting sleeves 32 can be fixed to one longitudinal thin cutter 33, or more than four cutting sleeves 32 can be fixed to one longitudinal thin cutter 33. This adjusts the distance between two adjacent longitudinal thin cutters 33, thereby adjusting the length of the thin segments cut by the longitudinal thin cutters 33, which are then cut by the transverse cutting blades 321 to form tobacco shreds. The operator adjusts the number of longitudinal thin cutters 33 according to the required length of tobacco shreds during rolling to ensure that the cut tobacco shreds meet the requirements.

[0040] The tobacco receiving box 4 is located at the bottom of the mounting cavity and is used to receive tobacco shreds. The tobacco receiving box 4 is located below the cutting roller 3 and the support roller 2, so that the tobacco shreds cut by the cutting roller 3 fall into the tobacco receiving box 4.

[0041] The fixing component 6 is used to fix the cutting roller 3 and the support roller 2. Fixing the cutting roller 3 and the support roller 2 by fixing the cutting roller 3 and the support roller 2 by fixing the cutting roller 3 and the support roller 2 on the housing 1 ensures the stability of the cutting roller 3 and the support roller 2, and also ensures the safety and stability of the cutting roller 3 and the support roller 2 during operation.

[0042] The present invention arranges the slicing roller 3 and the support roller 2 in parallel and fixes them in the mounting cavity respectively. The slicing roller 3 includes multiple slicing sleeves 32, multiple longitudinal thin cutters 33 and a fixed shaft 31. The slicing sleeves 32 and the longitudinal thin cutters 33 are all sleeved on the fixed shaft 31, and at least two slicing sleeves 32 fix one longitudinal thin cutter 33. The outer peripheral wall of the slicing sleeve 32 is provided with transverse slicing cutters 321 extending along the axial direction of the slicing sleeve 32. The wire receiving box 4 is arranged at the bottom of the mounting cavity and the slicing roller 3 and the support roller 2 are fixed by the fixing component 6. In use, the operator first adjusts the number of cutting sleeves 32 and longitudinal thin cutters 33 according to the required tobacco length during rolling; then, the cutting roller 3 and support roller 2 are fixed by the fixing component 6; then, the reconstituted tobacco sheet 101 is cut by the longitudinal thin cutter 33 and the transverse thin cutter 321, and then the tobacco shreds of the required size are formed after being cut by the longitudinal thin cutter 33 and the transverse thin cutter 321 and collected in the receiving box 4. The structure is simple, easy to install, and makes the tobacco shreds more adaptable during rolling, meeting the needs of the operator.

[0043] Furthermore, there are multiple transverse slicing blades 321, and the distance between two adjacent transverse slicing blades 321 is 1mm-3mm. In this embodiment, the distance between two adjacent transverse slicing blades 321 is 2mm.

[0044] In one embodiment of the segmented fixed-length thin sheet filament slitting device of the present invention, such as Figures 1 to 3 As shown, an annular knife-avoiding groove 22 is provided on the outer peripheral wall of the support roller 2. The annular knife-avoiding groove 22 is evenly spaced along the axial direction of the support roller 2, and there is a smooth area 21 between two adjacent annular knife-avoiding grooves 22.

[0045] In this embodiment, the annular blade avoidance groove 22 has a certain depth so that the longitudinal thin cutter 33 will not collide with the outer peripheral wall of the support roller 2 when it rotates.

[0046] It should be noted that after the longitudinal thin cutter 33 cuts the reconstituted tobacco sheet 101 into thin segments, the thin segments fall into the smooth area 21 and adhere to the smooth area 21. Then, when the cutting sleeve 32 rotates, the longitudinal thin cutter 33 cuts the thin segments to form tobacco shreds.

[0047] The present invention provides an annular knife-avoiding groove 22 on the outer peripheral wall of the support roller 2. The annular knife-avoiding groove 22 is evenly spaced along the axial direction of the support roller 2, and there is a smooth area 21 between two adjacent annular knife-avoiding grooves 22. This avoids the situation where the longitudinal thin cutter 33 does not collide with the outer peripheral wall of the support roller 2 when cutting the reconstituted tobacco sheet 101.

[0048] In one embodiment of the segmented fixed-length thin sheet filament slitting device of the present invention, such as Figures 3 to 4As shown, the shredding assembly also includes an arc-shaped guide plate 9, which is fixed on the housing 1. The arc-shaped guide plate 9 is used to limit the reconstituted tobacco sheet 101. The arc-shaped guide plate 9 corresponds to the smooth area 21. The arc-shaped guide plate 9 and the outer peripheral wall of the support roller 2 form a conveying channel for the reconstituted tobacco sheet 101.

[0049] In this embodiment, the arc-shaped guide plate 9 is installed above the support roller 2, and the position of the arc-shaped guide plate 9 can be adjusted up and down. The inner diameter of the arc-shaped guide plate 9 is slightly larger than the diameter of the support roller 2, and the thickness of the first end of the arc-shaped guide plate 9 is less than the thickness of the second end of the arc-shaped guide plate 9. Specifically, the thickness of the arc-shaped guide plate 9 gradually increases from the first end of the arc-shaped guide plate 9 to the second end of the arc-shaped guide plate 9, and then remains constant.

[0050] The reconstituted tobacco sheet 101 is placed in the reconstituted tobacco sheet conveying channel. The first end of the arc-shaped guide plate 9 acts on the reconstituted tobacco sheet 101, causing the reconstituted tobacco sheet 101 to enter between the shredder roller 3 and the support roller 2, and then be cut by the shredder roller 3.

[0051] The present invention fixes the arc-shaped guide plate 9 on the housing 1 and makes multiple arc-shaped guide plates 9 correspond to the smooth area 21 respectively. The arc-shaped guide plate 9 and the outer peripheral wall of the support roller 2 form a conveying channel for the reconstituted tobacco sheet 101, which has a limiting effect on the reconstituted tobacco sheet 101, so that the reconstituted tobacco sheet 101 can be cut by the shredding roller 3.

[0052] In one embodiment of the segmented fixed-length thin sheet filament slitting device of the present invention, such as Figures 3 to 4 As shown, the arc-shaped guide plate 9 is provided with multiple ventilation holes 91 and grooves 92. The first end of the arc-shaped guide plate 9 is connected to the housing 1. The grooves 92 are evenly arranged at the second end of the arc-shaped guide plate 9 and are arranged opposite to the longitudinal thin cutter 33.

[0053] Specifically, the arc-shaped guide plate 9 has a hollow structure, and the groove 92 is provided on the side of the arc-shaped guide plate 9 adjacent to the transverse slicing blade 321. The diameter of the ventilation hole 91 is 1mm-3mm; in this embodiment, the diameter of the ventilation hole 91 is 1mm.

[0054] Compressed air is introduced into the arc-shaped guide plate 9. The compressed air forms an air knife through the ventilation hole 91, pressing the reconstituted tobacco sheet 101 against the surface of the support roller 2. This prevents the vortex wind generated when the cutting roller 3 and the support roller 2 move, which would cause the reconstituted tobacco sheet 101 to move irregularly and affect the cutting efficiency.

[0055] It should be noted that there are multiple grooves 92, and the multiple grooves 92 are respectively arranged opposite to multiple transverse slicing blades 321, so that the transverse slicing blades 321 will not collide with the arc-shaped guide plate 9 when cutting the reconstituted tobacco sheet 101.

[0056] In one embodiment of the segmented fixed-length thin sheet filament slitting device of the present invention, such as Figures 1 to 6 As shown, the shredding assembly also includes a locking sleeve 34, which is disposed at both ends of the shredding roller 3.

[0057] This invention fixes multiple cutting sleeves 32 and multiple longitudinal thin cutters 33 by placing locking sleeves 34 at both ends of the cutting roller 3. This ensures the stability of the cutting sleeves 32 and the longitudinal thin cutters 33 mounted on the fixed shaft 31, and avoids the problem of the cutting sleeves 32 and the longitudinal thin cutters 33 shifting during operation, which would cause changes in the cutting size. This effectively improves the cutting efficiency and cutting quality of tobacco shreds.

[0058] In one embodiment of the segmented fixed-length thin sheet slitting device of the present invention, first connecting holes (not shown in the figure) are correspondingly provided on both sides of the housing 1, and the fixing component 6 includes a first mounting bearing 61. The inner peripheral wall of the first mounting bearing 61 is connected to both ends of the support roller 2, and the outer peripheral wall of the first mounting bearing 61 is connected to the first mounting hole.

[0059] In this embodiment, the support roller 2 also includes a drive shaft 23, with both ends of the drive shaft 23 connected to the inner peripheral wall of the first mounting bearing 61, and the support roller 2 is sleeved on the drive shaft 23.

[0060] The present invention fixes the support roller 2 onto the housing 1 by providing first connecting holes on both sides of the housing 1, connecting the inner peripheral wall of the first mounting bearing 61 to both ends of the support roller 2, and connecting the outer peripheral wall of the first mounting bearing 61 to the first mounting hole, thereby ensuring the stability of the rotation and installation of the support roller 2.

[0061] In one embodiment of the segmented fixed-length thin sheet wire cutting device of the present invention, the housing 1 is provided with second connecting holes (not shown in the figure) on both sides, the fixing component 6 includes a second mounting bearing 62, the inner peripheral wall of the second mounting bearing 62 is connected to both ends of the fixing shaft 31, and the outer peripheral wall of the second mounting bearing 62 is connected to the second mounting hole.

[0062] The present invention provides second connecting holes on both sides of the body, connects the inner peripheral wall of the second mounting bearing 62 to both ends of the fixed shaft 31, and connects the outer peripheral wall of the second mounting bearing 62 to the second mounting hole, thereby fixing the fixed shaft 31 to the housing 1. This allows the fixed shaft 31 to stably drive the slicing sleeve 32 and the longitudinal thin cutter 33 to rotate, ensuring the stability of the rotation and installation of the fixed shaft 31.

[0063] Furthermore, such as Figure 5As shown, the fixing component 6 also includes a bearing thrust ring 7, which is respectively sleeved on both ends of the transmission shaft 23 and the fixed shaft 31. The bearing thrust ring 7 is located outside the housing 1 and between the fixing nut 8 and the housing 1, so as to prevent the first mounting bearing 61 and the second mounting bearing 62 from being removed from the first connecting hole and the second connecting hole, which would cause the rotation of the cutting roller 3 and the support roller 2 to malfunction.

[0064] In one embodiment of the segmented fixed-length thin sheet filament slitting device of the present invention, such as Figures 1 to 6 As shown, the diameter of the second connecting hole is larger than the outer diameter of the second mounting bearing 62.

[0065] The segmented fixed-length thin filament slitting device also includes an adjustment component 5, which includes a first adjustment handle 51 and a second adjustment handle 52. The first adjustment handle 51 and the second adjustment handle 52 are respectively connected to the outer peripheral wall of the second mounting bearing 62 and are used to move the filament cutting roller 3 to adjust the distance between the filament cutting roller 3 and the support roller 2.

[0066] This invention adjusts the distance between the cutting roller 3 and the support roller 2 by setting the diameter of the second connecting hole to be larger than the outer diameter of the second mounting bearing 62, and connecting the first adjusting handle 51 and the second adjusting handle 52 to the outer peripheral wall of the second mounting bearing 62 respectively. By rotating the first adjusting handle 51 and the second adjusting handle 52, the position of the cutting roller 3 is moved, thereby enabling the longitudinal thin cutter 33 and the transverse thin cutter 321 to cut the reconstituted tobacco sheet 101 into tobacco shreds, effectively ensuring cutting efficiency.

[0067] In one embodiment of the segmented fixed-length thin sheet filament slitting device of the present invention, such as Figures 1 to 6 As shown, the fixing component 6 also includes a fixing nut 8. The cutting roller 3 and the support roller 2 are fixed to the housing 1 by the fixing nut 8. This arrangement further increases the stability of the cutting roller 3 and the support roller 2 fixed to the housing 1.

[0068] The operation process of the regional fixed-length thin-sheet wire cutting device of the present invention is as follows:

[0069] Step 1: Convey the dried reconstituted tobacco sheet 101 into the housing 1;

[0070] Step 2: One end of the reconstituted tobacco sheet 101 is fed onto the support roller 2. Under the guidance of the arc-shaped guide plate 9 and the action of compressed air, the reconstituted tobacco sheet 101 is pressed against the surface of the support roller 2.

[0071] Step 3: The reconstituted tobacco sheet 101 pressed onto the surface of the support roller 2 is first cut along the direction of movement by the longitudinal thin cutter 33 of the cutting roller 3 to form long strips of thin segments in order to obtain the required tobacco length.

[0072] Step 4: After slicing, the long strips of thin segments are cut by the transverse slicing blade 321 on the slicing sleeve 32 under the drive of the support roller 2 to obtain the required tobacco shred width.

[0073] Step 5: The tobacco shreds with the required width and length, formed after being cut by the longitudinal thin cutter 33 and the transverse shredder 321, are conveyed to the receiving box 4.

[0074] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
