[0072] See appendix Figure 1 -Appendix Figure 2 , attached Figure 1 -Appendix Figure 2 A schematic diagram of the overall structure of a twist forming apparatus according to an embodiment of this application is shown. The twist forming apparatus includes a twisting wheel 100, which is configured to rotate about a first direction.

[0073] A rubbing-plate heating soldering iron 300 is disposed on one side of the radial outer wall of the rubbing roller 100; a rubbing zone is formed between the rubbing roller 100 and the rubbing-plate heating soldering iron 300;

[0074] The adjustment component 400 includes a starting rail 420; the starting rail 420 is slidably set on the rubbing plate heating soldering iron 300 for feeding the cigarette into the rubbing zone.

[0075] In some embodiments, the rubbing roller 100 rotates continuously along a first direction to stably adsorb and transport the cigarettes to be rubbed, providing continuous power and positioning support for rubbing. The rubbing plate heating soldering iron 300 is fixedly arranged on the radially outer side of the rubbing roller 100, and the two arc-shaped relative structures enclose a sealed rubbing area.

[0076] The starting rail 420 of the adjusting component 400 can slide relative to the corrugated heating soldering iron 300. During operation, it lifts up the cigarette embedded in the groove of the corrugating roller 100 and accurately feeds it into the corrugating area between the corrugating roller 100 and the corrugated heating soldering iron 300, so that the cigarette rolls synchronously with the rotation of the corrugating roller 100 to complete the wrapping and bonding of the tipping paper. At the same time, the adhesive is cured by the constant temperature heat of the corrugated heating soldering iron 300.

[0077] In some embodiments, the uniform rotation of the joining roller 100 ensures smooth cigarette feeding and a consistent joining rhythm. The soldering iron 300, heated by the joining plate, rapidly cures the adhesive, preventing issues such as tipping paper opening, air leakage, and detachment. The sliding adjustment function of the starting rail 420 allows for precise calibration of the cigarette feeding position and material gap, adapting to different production conditions and effectively avoiding quality defects such as cigarette flattening, wrinkling, and misalignment, thus improving the precision of cigarette joining and product consistency.

[0078] See appendix Figure 2 The rubbing forming device also includes a measuring rod 500; the measuring rod 500 is inserted between the rubbing roller 100 and the starting rail 420 along the first direction; one side of the radial outer wall of the measuring rod 500 abuts against the rubbing roller 100, and the other side of the radial outer wall of the measuring rod 500 abuts against the starting rail 420, for calibrating the gap between the starting rail 420 and the rubbing roller 100.

[0079] In some embodiments, during gap calibration, a measuring rod 500 is inserted between the rubbing roller 100 and the starting rail 420 along a parallel first direction. The outer walls on both sides of the cylindrical measuring rod 500 are respectively attached to the outer circumferential surface of the rubbing roller 100 and the smoke-pushing part of the starting rail 420. The fixed outer diameter of the measuring rod 500 itself is used as the standard reference size to limit the radial distance between the rubbing roller 100 and the starting rail 420, thereby completing the gap calibration.

[0080] In some embodiments, a standard outer diameter measuring rod of 500 is used for double-sided positioning, and the gap value is standardized to eliminate the error of manual visual inspection. The gap between the starting rail 420 and the twisting roller 100 is accurately calibrated to avoid the cigarette being pushed in place due to excessive gap or the cigarette being squeezed and damaged due to insufficient gap, thereby improving the stability of twisting and forming and the product qualification rate.

[0081] In some embodiments, four cigarette outer diameter specifications are provided: 5.4mm for slim cigarettes, 6.2mm for medium-slim cigarettes, 6.37mm for medium cigarettes, and 7.8mm for standard cigarettes. Each specification is matched with a dedicated measuring rod 500 with an outer diameter equal to the corresponding value. When changing the production cigarette specification, the measuring rod 500 with the corresponding outer diameter is selected. The outer diameter of the measuring rod is used as the standard gap reference between the starting rail 420 and the twisting wheel 100, and then the gap calibration is completed according to the adjustment procedure.

[0082] See appendix Figure 2 and attached Figure 5 The measuring rod 500 includes a fitting groove 510; the fitting groove 510 is formed on the outer wall of the measuring rod 500 facing the starting rail 420; the starting rail 420 includes a smoke-pushing blade 421; the smoke-pushing blade 421 is disposed on the side of the starting rail 420 facing the measuring rod 500; the smoke-pushing blade 421 is inserted into the fitting groove 510, and the measuring rod 500 abuts against the smoke-pushing blade 421 through the fitting groove 510.

[0083] In some embodiments, the measuring rod 500 has a fitting groove 510 on the outer wall of the starting rail 420, and the smoke-pushing blade 421 at the front end of the starting rail 420 is inserted into the fitting groove 510. The groove body forms a wrapping and limiting effect on the smoke-pushing blade 421, restricting the measuring rod 500 from circumferential rotation and radial displacement. The groove depth of the fitting groove 510 is 0.7mm.

[0084] When calibrating the gap, the outer wall of one side of the measuring rod 500 is pressed against the outer circle of the rubbing wheel 100, and the other side is clamped by the fitting groove 510 to push the smoke blade 421, so that the measuring rod 500 always maintains a standard posture and accurately separates the rubbing wheel 100 and the starting rail 420 with its own fixed outer diameter, thereby determining the standard gap size.

[0085] In some embodiments, the fitting groove 510 and the cigarette pusher blade 421 are interlocked to firmly constrain the position of the measuring rod 500, preventing the measurement reference from shifting due to the sliding or flipping of the measuring rod 500. This ensures that the outer walls on both sides of the measuring rod 500 are synchronously and tightly fitted to the rubbing wheel 100 and the starting rail 420, improving the gap calibration accuracy. After the gap is accurately adjusted, the cigarette is pushed smoothly, preventing defects such as cigarette compression deformation, tipping paper wrinkling, and incomplete pushing caused by gap deviation. At the same time, it reduces the difficulty of repeated manual fine-tuning.

[0086] See appendix Figure 1The twisting and forming device also includes a rotating component 200; the rotating component 200 is rotatably disposed on one side of the twisting wheel 100 around a first direction; the twisting plate heating soldering iron 300 is fixedly connected to the rotating component 200;

[0087] The adjustment assembly 400 also includes a sliding seat 410; the sliding seat 410 is slidably disposed on the rotating assembly 200, and the starting rail 420 is fixedly connected to the sliding seat 410 on the side facing the rubbing wheel 100.

[0088] In some embodiments, the rotating assembly 200 can be rotatably arranged on the side of the rubbing roller 100 around a first direction, and the rubbing plate heating soldering iron 300 is fixedly mounted on the rotating assembly 200 and rotates synchronously with the rotating assembly 200, so as to facilitate the overall opening of the rubbing plate heating soldering iron 300 for cleaning and maintenance of the inside of the rubbing area.

[0089] In some embodiments, the sliding seat 410 of the adjusting component 400 is slidably mounted on the rotating component 200, and the starting rail 420 is fixed on the side of the sliding seat 410 near the twisting wheel 100. The sliding seat 410 can generate a sliding displacement relative to the rotating component 200, thereby driving the starting rail 420 to move closer to or further away from the twisting wheel 100, thereby changing the gap between the starting rail 420 and the twisting wheel 100.

[0090] In some embodiments, the rotating component 200 drives the entire rubbing plate heating soldering iron 300 to rotate, exposing the rubbing roller 100 without disassembling the soldering iron, making equipment maintenance and cleaning of accumulated adhesive convenient. The sliding seat 410 achieves smooth sliding based on the rotating component 200, driving the starting rail 420 to stably and finely adjust its position. The adjustable stroke is controllable and can accurately match the standard gap calibrated by the measuring rod 500, ensuring the stable posture of the cigarette pushed by the starting rail 420, reducing cigarette squeezing and wrinkling failures. At the same time, the structure has a high degree of integration, simplifying the disassembly and maintenance process.

[0091] See appendix Figure 3 The rotating assembly 200 also includes an adjusting screw 230; the adjusting screw 230 is threadedly connected to the rotating assembly 200, and the sliding seat 410 abuts against the adjusting screw 230; the twisting forming device adjusts the gap between the starting rail 420 and the twisting wheel 100 by adjusting the adjusting screw 230.

[0092] In some embodiments, the rotating assembly 200 is equipped with an adjusting screw 230, which forms a threaded drive engagement with the rotating assembly 200. The end face of the sliding seat 410 is in close contact with the end of the adjusting screw 230 for limiting. By rotating the adjusting screw 230 in both forward and reverse directions, the screw end is extended or retracted using the threaded feed characteristics. This pushes the sliding seat 410 to slide smoothly on the rotating assembly 200, causing the starting rail 420 fixed on the sliding seat 410 to move synchronously. This precisely changes the radial distance between the starting rail 420 and the rubbing wheel 100, completing the gap fine-tuning operation.

[0093] In some embodiments, relying on the threaded fine-tuning structure of the adjusting screw 230, the gap of the starting rail 420 can be precisely adjusted in a small and stepless manner, with uniform and controllable adjustment stroke, eliminating the deviation problems of traditional manual coarse adjustment; in conjunction with the aforementioned calibration benchmark of the measuring rod 500, the standard working gap can be quickly calibrated to ensure the accurate and stable cigarette feeding position of the starting rail 420. At the same time, the thread self-locking performance can lock the adjustment position, preventing gap deviation caused by equipment vibration, and ensuring the long-term stability of cigarette rolling and forming quality.

[0094] See appendix Figure 2 -Appendix Figure 3 The forming device also includes a measuring rod support 600; the measuring rod support 600 is fixedly connected to the rubbing board heating soldering iron 300; the measuring rod support 600 includes a socket 620; the socket 620 is opened in the measuring rod support 600 along a first direction, and the measuring rod 500 is inserted into the socket 620.

[0095] In some embodiments, the measuring rod holder 600 is fixedly connected to the washboard heating soldering iron 300. The holder has a through hole 620 extending along a first direction, and the measuring rod 500 can be axially inserted into the through hole 620 for positioning. During gap calibration, the measuring rod 500 is inserted from the through hole 620. After calibration, it is inserted back into the through hole 620 and then pulled out. The through hole 620 provides circumferential and radial constraints on the measuring rod 500, limiting its shaking and falling.

[0096] In some embodiments, the measuring rod holder 600 is arranged with the washboard heating soldering iron 300, and the measuring rod 500 is housed in the socket 620. The socket 620 defines the orientation of the measuring rod 500, eliminating the need for additional alignment when using the insertion gap, shortening the calibration operation time, saving the manual operation of holding the measuring tool in and out of the operating area, and reducing safety hazards.

[0097] In some embodiments, the measuring rod holder 600 has multiple sets of insertion holes 620 with different inner diameters, the inner diameters of which match the outer diameters of four measuring rods 500 of different specifications: 5.4mm, 6.2mm, 6.37mm, and 7.8mm. Different specifications of measuring rods 500 can be inserted into the corresponding insertion holes 620 for storage and positioning. When changing the cigarette specification, the measuring rod 500 in the corresponding hole can be directly removed for gap calibration.

[0098] See appendix Figure 2 -Appendix Figure 3 and attached Figure 5 The measuring rod support 600 includes a first adjustment hole 610; the first adjustment hole 610 is formed in the measuring rod support 600 and is configured as a straight groove; the rubbing board heating soldering iron 300 includes a first positioning hole 320; the first positioning hole 320 is formed on the side of the rubbing board heating soldering iron 300 facing the measuring rod support 600.

[0099] The rubbing forming device also includes a locking component 700; the locking component 700 is inserted into the first adjustment hole 610 and the first positioning hole 320, and the measuring rod support 600 is detachably connected to the rubbing board heating soldering iron 300 through the locking component 700.

[0100] In some embodiments, the measuring rod holder 600 has a long slotted first adjustment hole 610, and the washboard heating soldering iron 300 is correspondingly provided with a first positioning hole 320. The locking component 700 passes through the first adjustment hole 610 and the first positioning hole 320 to complete the assembly. After the locking component 700 is released, the measuring rod holder 600 can be moved horizontally based on the slot clearance of the first adjustment hole 610, thereby fine-tuning the alignment position of the insertion hole 620 and the measuring rod 500. After adjustment, the locking component 700 is locked to fix the measuring rod holder 600 on the washboard heating soldering iron 300.

[0101] In some embodiments, the first adjustment hole 610 has a straight groove structure, providing an adjustable margin for the assembly position of the gauge rod holder 600, which can adapt to the alignment requirements of gauge rods 500 of different specifications. The locking component 700 enables quick assembly and disassembly; when inspecting the washboard heating soldering iron 300, the gauge rod holder 600 can be directly removed without assembly interference. The adjustable position of the holder ensures that the gauge rod 500 is accurately aligned with the gap between the rubbing roller 100 and the starting rail 420, avoiding gauge insertion misalignment, improving gap calibration accuracy, and facilitating assembly and disassembly while reducing the difficulty of equipment maintenance.

[0102] See appendix Figure 2 -Appendix Figure 3 The locking assembly 700 includes: an inner hole locking member 710, which is inserted into the first adjustment hole 610 and the first positioning hole 320, and is used to limit the outer wall of one side of the measuring rod support 600.

[0103] Nut 720 is threadedly connected to the inner hole locking part 710; nut 720 abuts against the outer wall of the other side of the measuring bar support 600 and is used to limit the outer wall of the other side of the measuring bar support 600.

[0104] In some embodiments, the inner hole locking member 711 passes through the first adjustment hole 610 of the measuring rod bracket 600 and the first positioning hole 320 of the washboard heating soldering iron 300. One end of the inner hole locking member 710 abuts against the outer wall of one side of the measuring rod bracket 600 to form a one-sided limit. The nut 720 is screwed into the outer threaded section of the inner hole locking member 710. After tightening, it fits against the outer wall of the other side of the measuring rod bracket 600 and clamps the measuring rod bracket 600 with the inner hole locking member 710. With the long groove structure of the first adjustment hole 610, the installation position of the measuring rod bracket 600 can be slidably adjusted by loosening the nut 720. After the adjustment is completed, the nut 720 is tightened to complete the bracket fixation.

[0105] In some embodiments, the inner hole locking member 710 and the nut 720 clamp the limiting measuring rod bracket 600 on both sides, resulting in uniform clamping force and preventing the bracket from shifting under equipment vibration. Loosening the nut 720 allows for quick adjustment of the bracket position, simplifying disassembly, assembly, and alignment operations. It also allows for flexible correction of the insertion position of the measuring rod 500, ensuring accurate alignment during measuring rod calibration gaps.

[0107] The outer cylinder 711 includes: an abutting part 7112, which abuts against the outer wall of one side of the measuring bar support 600 and is used to limit the outer wall of one side of the measuring bar support 600.

[0108] The elastic arm 7113 is disposed on the side of the outer cylinder 711 facing the corrugated heating soldering iron 300; the elastic arm 7113 is at least partially inserted into the first positioning hole 320.

[0109] The extrusion member 713 is slidably disposed on the outer cylinder 711 and is used to extrude the elastic arm 7113;

[0110] Bolt 712 is rotatably disposed inside the outer cylinder 711; bolt 712 is threadedly connected to extruder 713 and is used to drive extruder 713 to extrude elastic arm 7113.

[0111] In some embodiments, the outer cylinder 711 passes through the first adjusting hole 610 and the first positioning hole 320, and the abutting portion 7112 of the outer cylinder 711 is pressed against the outer wall of one side of the measuring rod support 600 to achieve unilateral limiting. An elastic arm 7113 is provided at one end of the outer cylinder 711 that extends into the first positioning hole 320. An extrusion member 713 is slidably assembled inside the outer cylinder 711. A rotatable bolt 712 is threadedly engaged with the extrusion member 713. When the bolt 712 is tightened, the extrusion member 713 moves axially via thread transmission. The extrusion member 713 presses against the elastic arm 7113, causing it to expand outwards. After expansion, the elastic arm 7113 tightly clamps the inner wall of the first positioning hole 320, achieving locking and fixing between the outer cylinder 711 and the washboard heating soldering iron 300. Furthermore, the bolt 712 is configured as an M8 hex socket head cap screw.

[0112] In some embodiments, the tensioning structure, formed by the bolt 712 and the clamping member 713, can securely lock the outer cylinder 711 into the first positioning hole 320 of the washboard heating soldering iron 300, preventing the outer cylinder 711 from loosening due to equipment vibration. The abutment part 7112, in conjunction with the nut 720, clamps the measuring rod support 600 in both directions, while the tensioning structure locks the body of the outer cylinder 711, thus enhancing the assembly stability of the measuring rod support 600. Loosening the bolt 712 in the opposite direction releases the retraction of the elastic arm 7113, allowing for quick disassembly of the measuring rod support 600 and convenient maintenance and disassembly.

[0113] See appendix Figure 6 -Appendix Figure 7 The outer cylindrical component 711 also includes a threaded portion 7111; a nut 720 is threadedly connected to the threaded portion 7111.

[0114] The extrusion part 713 includes: a threaded hole 7131, which is axially formed in the extrusion part 713; and a bolt 712 is threadedly connected to the threaded hole 7131; the bolt 712 is threadedly connected to the extrusion part 713 through the threaded hole 7131.

[0115] The extrusion slope 7132 is disposed on the side of the extruder 713 facing the elastic arm 7113; the extrusion slope 7132 is configured to be inclined relative to the axial direction of the extruder 713.

[0116] In some embodiments, the outer cylinder 711 has a threaded portion 7111 on its outer side, for the nut 720 to engage and clamp the measuring rod bracket 600. The bolt 712 is screwed into the threaded hole 7131 in the axial direction of the extruder 713; rotating the bolt 712 allows the extruder 713 to move axially. The inclined extrusion ramp 7132 at the end of the extruder 713 moves along with the extruder, compressing the elastic arm 7113. The oblique thrust of the ramp radially expands the elastic arm 7113, locking it in place by clamping it in the first positioning hole 320.

[0117] In some embodiments, the threaded portion 7111, in conjunction with the nut 720, enables adjustable clamping of the gauge bar holder 600. The threaded hole 7131 and the bolt 712 form a precise threaded feed, and the pressing inclined surface 7132 converts the axial movement into radial tension force of the elastic arm 7113. The locking force is controllable, resistant to equipment vibration and not easy to loosen, and can be loosened by reversing the operation, making disassembly and adjustment simple.

[0118] See appendix Figure 3 -Appendix Figure 4 The starting rail 420 also includes a second adjustment hole 422; the second adjustment hole 422 is formed in the starting rail 420; the second adjustment hole 422 is configured as a straight slot.

[0119] The rubbing heating soldering iron 300 also includes a second positioning hole 310; the second positioning hole 310 is opened on the side of the rubbing heating soldering iron 300 facing the starting rail 420; the rubbing forming device also includes a fixing member; the fixing member is inserted into the second adjustment hole 422 and the second positioning hole 310, and the starting rail 420 is detachably connected to the rubbing heating soldering iron 300 through the fixing member.

[0120] In some embodiments, the starting rail 420 has a straight groove-type second adjustment hole 422, and the washboard heating soldering iron 300 is correspondingly provided with a second positioning hole 310. The fixing member passes through the second adjustment hole 422 and the second positioning hole 310. After loosening the fixing member, the starting rail 420 can be slightly moved using the allowance of the groove length of the second adjustment hole 422. After fine-tuning, the fixing member is locked to detachably fix the starting rail 420 to the washboard heating soldering iron 300.

[0121] In some embodiments, the second adjustment hole 422 of the straight groove structure provides the starting rail 420 with a fine-tuning margin, which can assist in correcting the smoke pushing position. The fasteners can be quickly disassembled and installed, and the replacement and maintenance of the starting rail 420 do not require complete disassembly of the components; the double limiting structure, together with the sliding seat 410, completes coarse and fine two-stage clearance adjustment, further improving the clearance calibration accuracy, and the lock is secure and not easily deviated during operation.

[0122] See appendix Figure 1 The rotating assembly 200 includes: a rotating shaft 210, which is rotatably disposed on one side of the rubbing roller 100 about a first direction;

[0123] A rotating base 220 is fixedly connected to a rotating shaft 210; a washboard heating soldering iron 300 is fixedly connected to the rotating base 220; and an adjusting component 400 is slidably set on the rotating base 220.

[0124] In some embodiments, the rotating shaft 210 is rotatably mounted on the side of the rubbing roller 100 in a first direction, the rotating seat 220 is fixed to the rotating shaft 210 and rotates synchronously, the rubbing plate heating soldering iron 300 is fixedly mounted on the rotating seat 220, and the adjusting component 400 is slidably mounted on the rotating seat 220. Rotating the rotating shaft 210 will cause the rotating seat 220, the rubbing plate heating soldering iron 300 and the adjusting component 400 to flip together, exposing the working surface of the rubbing roller 100.

[0125] In some embodiments, the rotating shaft 210 and the rotating base 220 form an integral flipping support structure, allowing the heat-generating soldering iron 300 to be lifted without disassembling parts, facilitating the cleaning of adhesive residue and inspection of the soldering area. The adjustment component 400 is integrated and installed on the rotating base 220, flipping synchronously with the soldering iron, ensuring that the adjustment reference does not shift, making debugging and maintenance operations convenient and efficient.

[0126] In some embodiments, a rotary cylinder is fitted on the back of the rotating shaft 210, and the output end of the cylinder is connected to the rotating shaft 210 for transmission. The rotating shaft 210 is driven to rotate around a first direction by the extension and rotation of the cylinder. The rotating shaft 210 drives the rotating seat 220, the hot soldering iron 300, and the adjusting component 400 to rotate synchronously as a whole, thereby automatically completing the switching between the closed operation state and the open maintenance state of the soldering station.

[0127] See appendix Figure 8 One embodiment of this application proposes an adjustment method, comprising the following steps:

[0128] S100, select measuring bar 500;

[0129] S200, Insert the measuring rod 500 between the adjusting starting rail 420 and the rubbing wheel 100;

[0130] S300, Adjust the position of the starting rail 420 relative to the washboard heating soldering iron 300;

[0131] One side of the radial outer wall of S400 and measuring bar 500 abuts against the rubbing wheel 100, and the other side of the radial outer wall abuts against the starting rail 420.

[0132] S500, extraction rod 500.

[0133] In some embodiments, in step S100, a standard measuring rod 500 with a corresponding outer diameter is selected according to the current cigarette specifications. The outer diameter of the measuring rod 500 corresponds to the standard gap value between the starting rail 420 and the joining wheel 100, which serves as the gap adjustment reference. Matching the measuring rod 500 ensures that the adjusted gap meets the process requirements, avoids gap deviation caused by selecting the wrong measuring tool, and reduces the problem of poor cigarette joining from the source.

[0134] In step S200, the selected measuring rod 500 is inserted axially along the first direction into the gap between the rubbing wheel 100 and the starting rail 420, so that the measuring rod 500 is in the middle calibration position between the two. At the same time, the smoke-pushing blade 421 of the starting rail 420 is engaged in the fitting groove 510 of the measuring rod 500, which limits the measuring rod 500 from flipping or slipping, thus providing a standard reference for gap calibration.

[0135] In step S300, the adjusting screw 230 on the rotating assembly 200 is rotated. The screw feeds axially and pushes the sliding seat 410 to slide on the rotating seat 220. The sliding seat 410 drives the starting rail 420 fixed on it to move synchronously, changing the distance between the starting rail 420 and the rubbing wheel 100. The adjustment is continuously fine-tuned until both sides of the measuring rod 500 are completely in contact with the workpiece.

[0136] In step S400, the position of the starting rail 420 is continuously fine-tuned so that the outer circumference of one side of the cylindrical measuring rod 500 is tightly fitted to the outer circle of the rubbing wheel 100, and the outer wall of the other side is fitted to the starting rail 420 push-off blade 421. The fixed outer diameter of the measuring rod 500 is used as the standard size to limit the standard radial gap between the rubbing wheel 100 and the starting rail 420. At the same time, the push-off blade 421 is engaged in the fitting groove 510 to constrain the measuring rod 500, prevent the measuring rod from shifting or tilting, and ensure that both sides are fully fitted.

[0137] In step S500, after confirming that the measuring rod 500 is tightly attached to the rubbing roller 100 and the starting rail 420 on both sides and that the position of the starting rail 420 is locked and fixed, the measuring rod 500 is pulled outward along the first direction to release the support and limit of the measuring rod 500 on the rubbing roller 100 and the starting rail 420, and restore the normal production gap space of the equipment.

[0138] This invention is equipped with a dedicated starting rail adjustment fixture assembly. Before debugging, the heating soldering iron 300 can be turned off by rotating the assembly 200 to close the rubbing plate. The part of the fixture that contacts the soldering iron is made of thick-walled 45 steel, which has excellent heat insulation and deformation resistance. The entire process does not require the user to reach into the high-speed rotating rubbing wheel 100 area to insert and adjust the measuring tool, effectively avoiding safety accidents such as high temperature burns and equipment pinching.

[0139] Before formal gap adjustment, the washboard heating soldering iron 300 can be flipped over to thoroughly clean the adhesive and debris from the working area of ​​the 100-inch jointing roller, eliminating gap interference caused by foreign objects. It comes with four high-precision measuring and machining gauges 500, corresponding to four process gaps: 5.4mm for thin support, 6.2mm for medium-thin support, 6.37mm for medium support, and 7.8mm for standard support. The measuring tools have uniform dimensions and a high degree of process standardization.

[0140] The tooling is easy to assemble, disassemble, and adjust. It relies on the 230 threaded adjusting screw for micro-feeding and the straight groove second adjusting hole 422 for auxiliary correction, making the gap adjustment precise and controllable. The success rate of a single adjustment can reach 95%. The overall debugging time is reduced by about 60%, eliminating the problems of left-right and high-low misalignment of the starting rail caused by traditional manual coarse adjustment.

[0141] The gauge rod holder 600, rotating component 200, and starting rail 420 are all designed for universal compatibility, allowing the entire fixture to be directly mounted on mainstream cigarette rolling and splicing units such as ZJ112, ZJ116, ZJ118, and ZJ119. The gauge rod holder 600, equipped with multi-diameter insertion holes 620, can store four different diameter gauge rods 500. When switching between the production of thin, medium-thin, medium, and standard cigarettes, only the corresponding gauge rod 500 needs to be replaced to complete the gap calibration, without needing to replace the entire fixture, making production changeovers flexible.

[0142] The ZJ112, ZJ116, ZJ118, and ZJ119 series of equipment are all cigarette rolling and forming machines independently developed by Changde Tobacco Machinery. The complete set consists of three parts: a tobacco feeding and forming machine, a rolling and forming machine, and a filter tip attaching machine. Its function is to roll tobacco into cigarettes and then attach filters. It is a core forming equipment for domestic cigarette factories and is suitable for all specifications of cigarettes, including standard, medium, medium-fine, and fine cigarettes.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
