Description
Technical Field
The invention relates to a sheet material crimping device, in particular to a crimping device for heating non-combustible tobacco sheets, and belongs to the technical field of extrusion continuous device design and manufacture.
Background
In the heating non-burning tobacco processing production process, the automatic-feeding raw material is generally a rolled tobacco sheet strip, the tobacco sheet strip is processed into tobacco rods through the existing pretreatment equipment, then the tobacco rods are wrapped by cigarette paper, and the tobacco rods are cut, rolled or rubbed through the downstream equipment to form the heating non-burning cigarette. In the processing of rolled tobacco sheets into tobacco rods, it is necessary to pretreat the tobacco sheets to varying degrees, namely: the tobacco sheets are processed into continuous tows with a certain width along the feeding direction so as to facilitate the convergence of tobacco shreds into rods. The pretreatment modes commonly used at present include embossing, shredding and the like. In practical production, the tobacco sheets are required to be continuously and sufficiently supplied, so that the tail of the old tobacco sheet to be used up and the head of the new tobacco sheet need to be connected, and the connecting section still has a certain tensile strength after pretreatment, so that the breakage rate of the connecting part is controlled at a lower level.
Currently, the main stream implementation manner of strip connection mainly comprises: with and without auxiliary material. The auxiliary materials adopted for auxiliary material connection are generally as follows: double-sided tape, water and other adhesive materials which do not pollute the strip, and the like, and the strip can be connected without auxiliary materials, and the strip can be connected without adding any auxiliary materials. In the non-auxiliary material connection, the main stream mode utilizes the deformation of the laminated material by physical extrusion to achieve the connection of the materials because the adhesive auxiliary material cannot be used. However, in the extrusion deformation process of the material, the situation that the embossing depth of the compression joint section is different due to uneven extrusion force distribution and the local tensile strength of the compression joint section is weak finally exists, and the situation is particularly obvious for heating non-burnt tobacco sheets with larger breadth. For example, chinese patent CN202210493772.8 discloses a sheet material press-bonding mechanism, in which a raised belt and a recessed belt penetrating along the axial direction of a roller are provided on a high roller surface, and this structure has no way to ensure constant press-bonding strength of each pressed region of a material during the pressing process due to the variation of the pressed area along with the rotation time of the roller during the actual press-bonding process, which eventually results in the situation that the local press-bonding strength of the press-bonding section is insufficient, and the occurrence of the difference in the thickness of the press-bonding lines on the press-bonding material, so that the press-bonding section has a risk of extremely breaking during the actual use, especially, the breakage rate cannot be controlled at a desired level after the material is cut into shreds.

The following technical scheme of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments so as to more intuitively understand the essence thereof.
Fig. 1 shows a schematic view of a two-roll (first and second roll) structure of a sheet material crimping apparatus according to an embodiment of the present invention. As shown in fig. 1, the sheet material press-connection device comprises a first roller 1 and a second roller 2 which are butted with each other, wherein the first roller 1 and the second roller 2 are respectively provided with a first roller shaft 18 and a second roller shaft 28, and the first roller shaft 18 and the second roller shaft 28 can be respectively connected with corresponding power machines so as to rotate under the drive of the corresponding power machines, so that the head and the tail of two continuous sheet materials entering between the first roller 1 and the second roller 2 are pressed and pressed to form a material strip connected into a whole. The first roll 1 is provided with a first extrusion die 12, the second roll 2 is provided with a second extrusion die 22, two first protrusion support belts 13 are provided at both ends of the first extrusion die 12, two second protrusion support belts 23 are provided at both ends of the second extrusion die 22, one first protrusion belt 15 and one first groove belt 16 are provided between the two first protrusion support belts 13, and one second protrusion belt 25 and one second groove belt 26 are provided between the two second protrusion support belts 23.
In other embodiments of the sheet material crimping apparatus of the present invention, one of the first and second extrusion dies 12, 22 may not be provided with raised and recessed bands, i.e., extrusion of sheet material may be accomplished as long as one of the first and second extrusion dies 12, 22 is provided with a raised band. For example, in addition to the embodiment shown in fig. 1, it may be implemented as follows: the circumferential surface of the first extrusion die 12 is provided with at least one first raised band 15 and at least one first recessed band 16 and the surface of the second extrusion die 22 is smooth, or the surface of the first extrusion die 12 is smooth and the circumferential surface of the second extrusion die 25 is provided with at least one second raised band 25 and at least one second recessed band 26.
In the configuration shown in fig. 1, as shown in fig. 6A, the first extrusion die 12 and the second extrusion die 22 are pressed against each other during the press-connection of the successive sheet materials 4, 5. At the same time, the first convex supporting band 13 and the second convex supporting band 23 abut against each other. Thereby, a fixed compression space (indicated by reference numeral 3 in fig. 6A) is formed between the first and second convex supporting belts 13, 23 for uniformly pressing the sheet materials 4, 5.
In some embodiments, the minimum vertical distance between the circumferential surfaces of the first extrusion die 12 and the second extrusion die 22 is less than or equal to 2 times the thickness of the sheet material within the fixed space formed when the first extrusion die 12 and the second extrusion die 22 are in compression. Also shown in fig. 6A, the minimum vertical distance between the circumferential surfaces of the first extrusion die 12 and the second extrusion die 22 in the compression space (i.e., the vertical distance H between the top surface of the first raised band 15 and the top surface of the second raised band 25 in fig. 6A) is less than or equal to 2 times the thickness of the sheet material. In this way, not only can it be ensured that sufficient extrusion force is provided in the pressing process, so that only a material of a specific thickness is allowed to pass through after the pressing, but also the pressing strength of the pressing material is ensured, so that the extrusion strength of the pressed continuous sheet materials 4 and 5 is basically uniformly distributed, and a material strip with uniform strength distribution in the material width direction is formed.
In other embodiments of the sheet material crimping apparatus of the present invention, the raised support strips on the first extrusion die 12 and the second extrusion die 22 may be provided in a variety of configurations, such as a single second raised support strip 23 at each end of the second extrusion die 22, as shown in fig. 6B, no raised support strip at each end of the first extrusion die 12, a single first raised support strip 13 at each end of the first extrusion die 12, no raised support strip at each end of the second extrusion die 22, a single first raised support strip 13 at one end of the first extrusion die 12, and a single second raised support strip 23 at an end of the second extrusion die 22 opposite the first extrusion die 12, as shown in fig. 6C. In any of the above configurations, the vertical distance H between the first and second raised strips 15, 25 is less than or equal to 2 times the thickness of the sheet material in the compression space formed by the press-fit of the first and second extrusion dies 12, 22.
Alternatively, the first roll shaft 18 and the second roll shaft 28 of the first roll 1 and the second roll 2 of the invention can be connected with a transmission mechanism, and the transmission mechanism is connected with a power machine, so that the two roll shafts 18 and 28 and the two rolls 1 and 2 are driven by the power machine to synchronously rotate through the transmission mechanism, and the head and the tail of two continuous sheet materials entering between the first roll 1 and the second roll 2 are extruded and pressed into a material belt with uniform intensity distribution.
As shown in fig. 1 and 6A, a first raised support band 13 is provided on both sides of the circumferential surface of the first extrusion die 12, and a second raised support band 23 is provided on both sides of the circumferential surface of the second extrusion die 22; as shown in fig. 6B, only one second convex supporting belt 23 may be provided at each end of the second extrusion die 22; as shown in fig. 6C, only one first convex supporting band 13 may be provided at each end of the first extrusion die 12; as shown in fig. 6D, a first raised support band 13 may be provided at one end of the first extrusion die 12, and a second raised support band 23 may be provided at the other end of the second extrusion die 22. The arrangement of the convex supporting belt can ensure that the embossing depth of the pressing section is consistent and the pressing strength distribution is even in the process of pressing the head and tail of two continuous sheet materials.
Further, as shown in fig. 1, on the first extrusion die 12, a first protrusion band 15 and a first groove band 16 are concomitantly provided between the first protrusion support bands 13 on both sides; a second protrusion band 25 and a second groove band 26 are provided in the second extrusion die 22 between the second protrusion support bands 23 on both sides. The arrangement of the raised belts and the concave belts can extrude the crimping sections with the same connecting strength and the consistent grain depth on the two continuous sheet materials.
Wherein, as shown in FIG. 7, the first and second raised strips 15, 25 and the first and second recessed strips 16, 26 are offset in position when the first and second extrusion dies 12, 22 are in meshed extrusion, such that successive sheet materials 4, 5 entering between the two extrusion dies 12, 22 are crimped into at least two offset crimp strips, ensuring that the raised strips 15, 25 of each extrusion die 12, 22 are crimped onto the sheet material.
In addition, as shown in fig. 1, the circular arc surface of the first extrusion die 12 is divided into a first circular arc surface (high roll surface) 17 and a second circular arc surface (low roll surface) 14 by the first land 15 and the first groove land 16, the circular arc surface of the second extrusion die 22 is divided into a third circular arc surface (low roll surface) 27 and a fourth circular arc surface (high roll surface) 24 by the second land 25 and the second groove land 26, wherein the surface of the first circular arc surface 17 is higher than the surface of the second circular arc surface 14, the surface of the fourth circular arc surface 24 is higher than the surface of the third circular arc surface 27, the second circular arc surface 14 and the fourth circular arc surface 24 are opposed to each other during the press-fitting of the first extrusion die 12 and the second extrusion die 22, and the first circular arc surface 17 and the third circular arc surface 27 are opposed to each other.
Preferably, the spacing between the second 14 and fourth 24 arcuate surfaces and the spacing between the first 17 and third 27 arcuate surfaces during the intermeshing extrusion of the first 12 and second 22 dies is greater than 2 times the thickness of the sheet material for creating advantageous removal conditions for crimp waste removal during the extrusion process.
In addition, as shown in fig. 1, an elastomer 11 is further disposed between the first extrusion die 12 and the first roller 1, and the elastomer 11 is matched with the bottom shape of the first extrusion die 12 in shape, and because the elastomer 11 is matched with the bottom shape of the first extrusion die 12 in shape, the elastomer can be compatible with processing and assembly errors of the first extrusion die 12, and meanwhile, impact of the moment of high-speed rotation contact when the first extrusion die 12 and the second extrusion die 22 are pressed can be greatly reduced, so that abrasion of the extrusion dies is reduced, and the service life of equipment is prolonged.
Alternatively, the elastic body 11 may be provided between the second extrusion die 22 and the second roller 2, or the elastic body 11 may be provided between the first extrusion die 12 and the first roller 1 and between the second extrusion die 22 and the second roller 2 at the same time.
Preferably, the hardness of the elastomer 11 is lower than the hardness of the first extrusion die 12 and the second extrusion die 22, so that the elastomer 11 can be extruded and deformed during operation, and then the resilience of the elastomer 11 ensures that the two extrusion dies 12 and 22 can have enough extrusion force during lamination.
As shown in fig. 4, according to another embodiment of the present invention, a supporting and limiting body 19 is disposed between the elastic body 11 and the first roller 1, and two radial sides of the supporting and limiting body 19 are respectively provided with a raised side edge 191 for limiting the elastic body 11 from excessively deforming to two side edges, preventing the two side edges of the elastic body 11 from extending outwards, and improving the service life of the elastic body 11.
FIG. 2 shows an enlarged view of the first extrusion die 12; fig. 3 shows an enlarged view of the second extrusion die 22. As shown in fig. 2 and 3, the first and second raised strips 15, 25 are each comprised of an arcuate strip section 151, 251 and a straight strip section 152, 252. Likewise, the first and second groove bands 16, 26 are also each comprised of arcuate band segments and straight band segments. It will be readily understood by those skilled in the art that although the arcuate belt segments 151, 251 are provided in the illustrated spiral configuration in this embodiment, they may be provided in a wavy configuration or in a continuously smoothly transitioned curved configuration, as long as excessive splice area is avoided.
Preferably, the arcuate belt segments 151, 251 (also including the arcuate belt segments of the first and second groove belts) have a length greater than the length of the linear belt segments 152, 252 (also including the linear belt segments of the first and second groove belts) which is 0 to 0.5 times the width of the sheet material for providing sufficient compression length to ensure a stable tension cut-off effect. Optionally, as shown in fig. 8, a plurality of polygonal protruding teeth may be provided on the first and second protruding strips 15, 25 at intervals, for reinforcing the extrusion trace and improving the splicing reliability. The depth of the first and second grooved belts 16, 26 on the arcuate surfaces of the first and second extrusion dies 12, 22, respectively, is less than or equal to the thickness of the sheet material to ensure that the grooved belts 16, 26 have the relief space required for crimping during extrusion, thereby achieving uniform crimping and reasonable crimp strength.
