Description

Technical Field

[0001] This application relates to the field of cigarette carton packaging machine technology, and in particular to a double-specification strip pull-belt knife device for a cigarette packaging machine and a cigarette packaging machine. Background Technology

[0002] In cigarette carton packaging, the precise positioning of the packing strap plays a crucial role in ensuring the product's appearance quality. With the diversification of market demand and the increasing variety of cigarette brands and specifications, higher demands are placed on the adaptability of packaging machinery. However, the existing YB95A carton packaging machine is only suitable for packaging single-brand cigarette cartons. When switching brands on the production line, the entire set of packing cutters and related components must be replaced, and the positions of the packing pull line and the packing strap cutter must be readjusted. This process is time-consuming and labor-intensive, resulting in long downtime, reduced production efficiency, and frequent component replacements can easily lead to equipment stability issues. For example, the packing strap position of Baisha (Ruizhongzhi) cigarettes is 120±5mm from the near end of the carton (inner end of the equipment), while that of Furongwang (Rongyaozhongzhi) cigarettes is 135±5mm. The significant difference in the packing strap positions between these two medium-length cigarette brands makes switching operations complex and cumbersome. Utility Model Content

[0020] See Figures 1 to 8 This application provides a double-specification strip pulling cutter device for a cigarette packaging machine, which is installed on the cigarette packaging machine body. The cigarette packaging machine body has a conveyor belt device, which has a conveyor belt for conveying strips and pulling threads. A strip-transfer station is provided along the conveying direction of the conveyor belt device, and the double-specification strip pulling cutter device is arranged at the strip-transfer station. The double-specification strip pulling cutter device includes: a strip-transfer cutter assembly, a roller assembly, and a thread pulling cutter assembly arranged sequentially along the conveying direction of the conveyor belt at the strip-transfer station. The strip-cutting knife assembly includes: a fixed knife 3 and a strip-cutting knife 4 arranged correspondingly on both sides of the conveyor belt; the strip-cutting knife is set on the knife holder of the cigarette packaging machine body on the lower side of the conveyor belt, and the fixed knife is set on the rotatable knife shaft of the cigarette packaging machine body on the upper side of the conveyor belt. The fixed knife rotates with the knife shaft to cooperate with the strip-cutting knife to achieve strip-cutting. The roller assembly includes: a conveyor roller 1 and a rubber roller 2 arranged correspondingly on both sides of the conveyor belt; the conveyor roller is provided with an avoidance notch 7; The wire-pulling knife assembly includes: wire-pulling knives 5 and wire-pulling rollers 6 arranged correspondingly on both sides of the conveyor belt; the wire-pulling knife is set on the wire-pulling knife holder, which is mounted on a rotatable knife holder shaft on the cigarette packaging machine body on the lower side of the conveyor belt, and the wire-pulling knife and the wire-pulling knife holder are located at the clearance notch of the conveyor roller; the wire-pulling knife works with the wire-pulling roller to achieve wire pulling and cutting.

[0021] It should be noted that the cigarette packaging machine body is the existing YB95A type carton outer transparent paper packaging machine. The cutting device of this application is adapted to the dual-specification carton pull-belt packaging application; specifically, taking the switch from Furongwang (Glory Medium) to Baisha (Rui Medium) as an example, in the carton through-cutting knife switch, the first through-cutting knife on the knife holder is replaced with the second through-cutting knife, and the carton pull-belt cutting position is changed from 173mm to 160mm; the fixed knife is disassembled and replaced when it is ineffective; the position of the pull-belt knife is adjusted, and the continuous displacement adjustment of the pull-belt knife along the axial direction of the carton can be achieved by sliding the pull-belt knife seat and then tightening the bolt, and the pull-belt roller is adjusted in the same way; thus, it can adapt to meet the carton pull-belt packaging requirements of two brands.

[0022] Furthermore, the strip cutter includes a first strip cutter and a second strip cutter; the first strip cutter and the second strip cutter have different cut distances at the pull-band cutting positions, while the rest of their structural designs are the same.

[0023] Furthermore, the distance between the cuts at the pull-in cut position of the first through-cut is 173mm, and the distance between the cuts at the pull-in cut position of the second through-cut is 160mm.

[0024] Furthermore, the conveyor rollers are made of aluminum alloy.

[0025] Furthermore, the pull wheel is disposed on a pull wheel seat, and the pull wheel seat is mounted on the pull wheel shaft disposed on the cigarette packaging machine body on the upper side of the conveyor belt.

[0026] Furthermore, the wire drawing tool holder is slidably sleeved on the tool holder shaft, and the wire drawing tool holder is provided with bolt locking holes, and locking bolts can be installed to fix the wire drawing tool holder on the tool holder shaft; The pulley seat is slidably mounted on the pulley shaft. The pulley seat is provided with bolt locking holes, and locking bolts can be installed to fix the pulley seat on the pulley shaft.

[0027] Axially adjustable wire cutter assembly: The continuous displacement adjustment of the wire cutter along the axial direction of the strip box is achieved by sliding the wire cutter holder and locking bolt. The adjustment range on the shaft meets the requirements of 110-140mm, which can cover the position requirements of the wire puller for two brands.

[0028] Replaceable conveyor roller module: The conveyor roller adopts a split design, and the reserved avoidance notch can effectively avoid interference with the wire drawing knife seat; the conveyor roller is an aluminum alloy roller. Aluminum alloy has good thermal conductivity. In high-speed operation or process sections that require heating / cooling (such as heat sealing, drying), the aluminum alloy roller can more effectively conduct or dissipate heat, helping to control the paper temperature and prevent heat deformation or sticking; the conductive aluminum alloy roller is grounded through the cigarette packaging machine frame connected to it, which helps to conduct away the static electricity generated during the strip / glass paper process; at the same time, it works in conjunction with a polyurethane rubber roller. The rubber roller, with its own elasticity, can better adapt to the slight unevenness of the paper during clamping or pressing, and provides a certain amount of cushioning, reducing the risk of indentation, abrasion or tearing of the paper; in addition, the combination of aluminum alloy roller and rubber roller also avoids the situation where the smooth surface of the two rollers is insufficient for friction, which would cause the strip transmission to move side to side during the conveying process.

[0029] In the application of switching from Furongwang (Glory Central Branch) to Baisha (Rui Central Branch) as an example, during the strip-through knife switching, the first through knife on the knife holder is replaced with the second through knife, and the fixed knife is ineffective and needs to be disassembled and replaced; during the adjustment of the pull knife position, the pull knife seat can be slid and the bolt can be tightened to achieve continuous displacement adjustment of the pull knife along the axial direction of the strip box. At the same time, the pull roller is adjusted by the pull roller seat in the same way, so as to adapt to meet the strip pull tape packaging requirements of the two brands.

[0030] Furthermore, both the wire-pulling knife holder and the wire-pulling wheel holder are segmented structures; the wire-pulling wheel holder includes a first segmented wheel holder and a second segmented wheel holder; the wire-pulling wheel is disposed on the first segmented wheel holder or the second segmented wheel holder, both of which have semi-circular arc grooves that match the wire-pulling wheel shaft, and both are correspondingly wrapped around the wire-pulling wheel shaft, and both are connected and fixed by locking bolts; The wire drawing tool holder includes a first segmented tool holder and a second segmented tool holder; the wire drawing tool is disposed on the first segmented tool holder or the second segmented tool holder. Both the first segmented tool holder and the second segmented tool holder have a semi-circular arc groove that matches the tool holder shaft. The two are correspondingly wrapped around the tool holder shaft, and the two are connected and fixed by locking bolts.

[0031] Specifically, both the wire cutter holder and the wire puller holder are square blocks. The square block has a semi-circular groove in the middle for fitting the mounting shaft, and threaded locking holes are designed on both sides of the semi-circular groove.

[0032] It should be noted that the cigarette packaging machine body of this application is the existing YB95A type outer transparent paper packaging machine. Taking the switch from Furongwang (Glory Medium) to Baisha (Rui Medium) as an example, during the switch of the through-cutting knife, the first through-cutting knife on the knife holder is replaced with the second through-cutting knife, and the fixed knife does not need to be disassembled and replaced; during the adjustment of the pull-line knife position, the continuous displacement adjustment of the pull-line knife along the axial direction of the carton can be achieved by sliding the pull-line knife seat and then tightening the bolt. At the same time, the pull-line roller is adjusted by the same displacement based on the pull-line roller seat, which can adapt to meet the carton pull-line packaging requirements of the two brands.

[0033] The dual-specification strip pull-belt cutter device for cigarette packaging machines disclosed in this application, through modular adjustment components, facilitates rapid switching of the pull-belt position, significantly reduces downtime, improves equipment adaptability, and has good application prospects.

[0034] This application also provides a cigarette packaging machine, including the aforementioned cutting tool device.

[0035] The beneficial effects of the cigarette packaging machine of this application correspond to the beneficial effects of the cutting tool device of this application, and will not be repeated here.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
