Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a roll peeling and recovery device. Background Art

[0002] According to relevant tobacco industry regulations, tobacco excipients are subject to monopoly management. Cigarette manufacturing involves two exclusive excipients: cigarette paper and tipping paper. Both excipients are wound in rolls. After use, the plastic core (referred to as the tail frame, hereinafter) must be separated from the remaining material (referred to as the tail material, hereinafter) and collected separately.

[0003] At present, the recycling of tail materials is similar to the recycling method of the core and tail paper in toilet paper. For example, the patent document with publication number CN206985359U discloses a paper tail separation and recycling device used in toilet paper roll production. The chassis is provided with an inclined guide rod, and the lower end of the guide rod is fixed to the inner wall of the chassis through a fixed seat. The mounting frame is provided with a cutting motor, a core cutter and a tail paper cutter. The driving shaft of the cutting motor is connected to the core cutter driving wheel on the core cutter rotating shaft and the tail paper cutter driving wheel on the tail paper cutter rotating shaft through a No. 1 transmission belt. The tail paper cutter is arranged at a position corresponding to the upper part of the guide rod, and the core cutter is arranged at a position corresponding to the lower part of the guide rod; the control box is electrically connected to the cutting motor through a wire.

[0004] In the prior art, the core is separated from the paper by cutting the paper wrapped around the outside of the core without cutting the core. To avoid damaging the core, a certain gap must exist between the blade of the tail paper cutter and the outer wall of the core. This results in a small amount of tail paper on the core not being cut, requiring subsequent stripping by a stripping device, which is a cumbersome operation. Utility Model Content

[0025] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] A roll stripping and recycling device, such as Figure 1 As shown, the apparatus comprises a mounting shaft 1 and a winding shaft 21, the axial directions of which are parallel. During use, the tail frame of the reel to be recovered is placed on the mounting shaft 1, and the free end of the tail material wound on the tail frame of the reel to be recovered is then connected to the winding shaft 21. By rotating the winding shaft 21, the tail material can be gradually unwound from the tail frame and wound onto the winding shaft 21 until the tail material is completely unwound from the tail frame, completing the separation of the tail material and the tail frame. To maintain the stability of the unwinding, a fixing plate 4 is also included, to which the mounting shaft 1 and the winding shaft 21 are both mounted.

[0027] Since the winding shaft 21 needs to rotate, a driving member 22 is also included. The structure of the driving member 22 is not limited. In some embodiments, such as Figure 2As shown, the driving member 22 is a motor, and the winding shaft 21 is mounted on a connecting shaft with a longer axial length. The portion of the connecting shaft protruding from the winding shaft 21 passes through a through-hole formed in the fixing plate 4 and is connected directly to the output shaft of the motor or via a speed reducer, thereby being driven by the motor to rotate. In some embodiments, to ensure the stability of the rotation of the winding shaft 21, a rotating bearing is further provided between the connecting shaft and the through-hole of the fixing plate 4.

[0028] Regarding the connection between the winding shaft 21 and the connecting shaft, in some embodiments, the winding shaft 21 and the connecting shaft are fixedly connected. In other embodiments, the winding shaft 21 and the connecting shaft are detachably connected. In some embodiments, the connection is detachable through an electromagnet structure: the winding shaft 21 is provided with an electromagnet, and the connecting shaft is provided with an iron piece that can be connected to the electromagnet. When the electromagnet is energized to generate magnetic attraction to the iron piece, the winding shaft 21 and the connecting shaft are connected and do not rotate relative to each other. The driving member 22 drives the connecting shaft, and then drives the winding shaft 21 to rotate; when the electromagnet is de-energized and can no longer attract the iron piece, the winding shaft 21 can be removed from the connecting shaft.

[0029] Regarding the connection between the winding shaft 21 and the end of the tail material, in some embodiments, the winding shaft 21 can be set as a cylinder with an open end, and its outer edge is processed with two sets of paper clamping grooves using wire cutting. When in use, the end of the tail material is passed through the paper clamping groove and the winding roller is manually rotated twice to clamp it. In other embodiments, based on the connection between the winding shaft 21 and the connecting shaft through the electromagnet structure, such as Figure 4 As shown, the winding shaft 21 further includes an iron pressing plate 23, wherein a fixed portion for fixing the tail material is formed between the iron pressing plate 23 and the surface of the winding shaft 21, and the end of the tail material is inserted into the fixed portion. Since the iron pressing plate 23 can also be attracted by the energized electromagnet, the end of the tail material can be pressed tightly against the winding shaft 21. At the same time, in order to prevent the iron pressing plate 23 from falling off when the electromagnet is not working, the iron pressing plate 23 and the winding shaft 21 are also connected by an elastic member whose telescopic direction is parallel to the radial direction of the winding shaft 21. In addition, in some embodiments, in order to further fix the end of the tail material, a pressing groove can be provided in the axial direction of the winding shaft 21 surface, and the iron pressing plate 23 is provided with a convex strip that can be inserted into the pressing groove. The end of the tail material is pressed into the pressing groove by the convex strip, so that the end of the tail material forms a concave-convex structure, thereby making it less likely to slide along the surface of the winding shaft 21. The pressing groove and the convex strip are preferably square in radial cross-section. In some embodiments, friction patterns are provided on the surface of the pressing groove and / or the convex strip to increase the friction force on the end of the tail material to improve the fixing effect.

[0030] Since the rotation of the winding shaft 21 drives the tail material to be unwound on the tail frame, the tail frame will also rotate. In order to ensure the stability of the unwinding of the tail frame, in this embodiment, the mounting shaft 1 is connected to the fixed plate 4 through a rotating bearing, and the tail frame is fixedly connected to the mounting shaft 1. Therefore, the mounting shaft 1 can drive the tail frame to rotate and unwind.

[0031] The fixed connection between the tail frame and the mounting shaft 1 means that the tail frame and the mounting shaft 1 do not rotate relative to each other, but the tail frame and the mounting shaft 1 should be detachable. This fixed connection method is not limited. In some embodiments, the fixed connection can be achieved by utilizing the keyway already provided on the tail frame for installing the rollers during the cigarette production process. Specifically, a spacer sleeve is threadedly connected to the mounting shaft 1, and a keyway is also provided on the outer wall of the spacer sleeve. By inserting a flat key into the keyway of the tail frame and the keyway of the spacer sleeve, the relative rotation between the spacer sleeve and the tail frame can be limited. Among them, the spacer sleeve serves as a connecting structure between the mounting shaft 1 and the tail frame. For tail frames with different inner diameters, spacer sleeves of different outer diameters can be replaced to adapt to the installation.

[0032] After the above unwinding, the tail frame with the tail material removed remains on the mounting shaft 1 and can be directly disassembled and recycled. However, the tail material is wound on the winding shaft 21, and it is not easy to directly extract the tail material from the winding shaft 21. Therefore, a cutting device for cutting the tail material on the winding shaft 21 is also included. Figure 2 As shown, the surface of the winding shaft 21 is provided with a groove 211 in the axial direction, and the cutting device includes a cutting knife 31 that can be inserted into the groove 211, and a telescopic member 32 that drives the cutting knife 31 to move along the groove 211 for cutting. The telescopic member 32 is not limited and can be a cylinder, which can be used to connect the cutting knife 31 to the cylinder piston rod. Figure 4 As shown, since the tail material is wound on the surface of the winding shaft 21, the cutting knife 31 that can be inserted into the groove 211 can definitely cut the tail material closest to the winding shaft 21, thereby completely cutting off the wound tail material. After the tail material is cut off, it can automatically fall off the winding shaft 21; at the same time, since there is inevitably friction between the cutting knife 31 and the tail material, the axial movement of the cutting knife 31 may also drive the tail material to move axially and fall directly off the winding shaft 21; finally, the fallen tail material can be manually recovered.

[0033] Preferably, the cutting knife 31 is arranged directly above the winding shaft 21, so that the cut-off point of the winding tail material is located above the winding shaft 21, which makes it easier for the tail material to automatically fall off the winding shaft 21. In order to ensure that the groove 211 corresponding to the cutting knife 31 is located just above after the winding shaft 21 completes the winding of the tail material, so as to allow the cutting knife 31 to be inserted, in some embodiments, the winding shaft 21 can be adjusted by manual rotation. In other embodiments, a plurality of grooves 211 can be arranged along the circumference of the winding shaft 21, so that there is always a groove 211 located above. In some embodiments, the winding shaft 21 can be designed: Figure 4As shown, the winding shaft 21 includes a groove portion and a correction portion 212 that are radially opposed. The groove portion is provided with a groove 211, and the mass of the correction portion 212 is greater than that of the groove portion; the mass of the other parts of the winding shaft 21 is uniform. The winding shaft 21 is connected to the connecting shaft via an electromagnet. When the driving member 22 is operating, the electromagnet also operates to attract the iron piece and the iron pressure plate 23, so that the connecting shaft, the winding shaft 21, and the iron pressure plate 23 are connected and cannot rotate relative to each other. The driving member 22 drives the connecting shaft to drive the winding shaft 21 to rotate, and then, with the iron pressure plate 23 clamping the end of the tail material, the tail material is wound. When the driving member 22 is not operating, the electromagnet also does not operate and no longer attracts the iron piece and the iron pressure plate 23. The winding shaft 21 can rotate around the connecting shaft. Then, under the action of the gravity of the correction portion 212, the winding shaft 21 naturally rotates until the groove 211 is located at the top and the correction portion 212 is located at the bottom. On this basis, in some embodiments, the installation position of the elastic member can be adjusted so that a fixed portion for pressing the end of the tailing is formed between the iron pressure plate 23 and the surface of the correction portion 212 of the winding shaft 21. Then, after the electromagnet stops working, the iron pressure plate 23 rotates with the correction portion 212 to be located below the winding shaft 21. Since the electromagnet no longer attracts the iron pressure plate 23 and the iron pressure plate 23's own gravity acts, the elastic member expands, so that the iron pressure plate 23 is no longer pressed against the winding shaft 21, allowing the cut tailing to completely fall off the winding shaft 21.

[0034] Since the cutting blade 31 moves axially to cut off the wound tail material, Figure 3 As shown, the two ends of the cutting blade 31 along the moving direction are respectively a front end 311 and a rear end 312, and the front end 311 is compared with the rear end 312 and is away from the telescopic member 32, and the front end 311 is provided with a first blade, and the winding tail material is broken forward by the first blade. In some embodiments, in order to further improve the cutting effect, the width of the cutting blade 31 perpendicular to the axial direction of the winding shaft 21 increases progressively along the direction from the front end 311 to the rear end 312. As the cutting blade 31 moves forward axially, the increasing width of the cutting blade 31 separates the tail material more open, making it easier for the tail material to fall off from the winding shaft 21. In some embodiments, the cutting blade 31 includes a bottom 313 near the groove 211, and the bottom is provided with a second blade to assist in cutting the tail material layer that has not been cut by the first blade.

[0035] In addition, the pausing of the driving member 22 and the extending of the telescopic member 32 are both performed after the tail frame has completely unwound the tail material. In order to be able to promptly suspend the rotation of the winding shaft 21 after the tail frame has completely unwound the tail material and to prevent the winding shaft 21 from continuing to rotate and causing the tail material thereon to spread out and affect subsequent cutting, in some embodiments, such as Figure 1As shown, the device also includes a proximity switch 51 electrically connected to the drive member 22 and the telescopic member 32, respectively, and a swing arm 52 for controlling the proximity switch 51. The swing arm 52 has one end hinged to the fixed plate 4 and the other end free. When the free end of the swing arm 52 naturally droops, the swing arm 52 blocks the proximity switch 51. The portion of the tail between the winding shaft 21 and the tail frame forms a tensioning portion. The distance from the tensioning portion to the hinged end of the swing arm 52 is less than the length of the swing arm 52. When the tail frame has not fully unwound the tail, the tensioning portion is tightened between the winding shaft 21 and the mounting shaft 1. At this time, the free end of the swing arm 52 overlaps the tensioning portion. Because the distance from the tensioning portion to the hinged end is less than the length of the swing arm 52, the swing arm 52 is tilted and cannot block the proximity switch 51. When winding is completed, the tensioning portion can no longer support the free end of the rocker arm 52, and the free end of the rocker arm 52 hangs down freely, thereby blocking the proximity switch 51, and then controlling the driving member 22 to pause and the telescopic member 32 to extend and cut through the electrical connection.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
