Technical Field

[0001] This utility model relates to the field of tobacco technology, and in particular to a cigarette packaging box unpacking device. Background Technology

[0002] During the packaging and transportation process, cigarettes are usually sealed in cigarette boxes for easy sorting and distribution. Before being delivered to retail outlets, the cigarette boxes need to be opened and the cigarettes taken out.

[0003] There are generally no dedicated unpacking devices for cigarette boxes; they are all opened manually by staff. Because the operation is done manually, the depth to which the utility knife cuts into the sealing tape of the cigarette box cannot be precisely controlled. Often, the utility knife cuts too deep into the cigarette box, scratching the entire outer packaging of the cigarettes. Since cigarettes are expensive, the damaged cigarettes cannot be sold, resulting in significant economic losses.

[0004] Ensuring that the outer packaging of the entire carton of cigarettes is not damaged during unpacking is a problem that current technology urgently needs to solve. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a cigarette box unpacking device that can accurately control the cutting depth of the blade and only unpack the cigarette box without damaging the entire pack of cigarettes inside the cigarette box.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example

[0023] like Figures 1 to 4As shown, a cigarette packaging box unpacking device includes a positioning structure 1 and a cutting structure 2. The positioning structure 1 includes a telescopic beam 101 and positioning beams 102 disposed at both ends of the telescopic beam 101 and perpendicular to and parallel to the telescopic beam 101. The side of the positioning beam 102 is provided with a groove 103 along the length direction of the positioning beam 102. The cutting structure 2 includes a slider 201, a telescopic arm 202, a knife holder 203, and a blade 204. The two sliders 201 are respectively slidably disposed in the grooves 103 of the positioning beam 102. The two ends of the telescopic arm 202 are respectively connected to the sliders 201. The knife holder 203 is slidably disposed on the telescopic arm 202. The blade 204 is mounted on the knife holder 203 with the blade facing downward. The positioning structure 1 can limit the movement trajectory of the blade holder 203. Since the movement of the blade holder 203 is limited by the telescopic arm 202, and the sliders 201 at both ends of the telescopic arm 202 are limited by the sliding groove 103 of the positioning beam 102, the entire cutting process can ensure that the blade moves horizontally and will not cut too deeply, reducing the risk of damaging the entire cigarette pack inside the cigarette box and reducing economic losses. The slitting structure 2 is used to slit the sealing tape of the cigarette pack at a fixed depth.

[0024] The positioning beam 102 includes a fixed section 1021 and a telescopic section 1022 fitted onto the fixed section 1021. One end of the fixed section 1021 is fixedly connected to the telescopic beam 101, and the other end of the fixed section 1021 is slidably connected to the telescopic section 1022. Slide grooves 103 are provided on both the fixed section 1021 and the telescopic section 1022, with the overlapping end of the slide groove 103 being an open port. The slide grooves 103 on the fixed section 1021 and the telescopic section 1022 together form a complete slide groove. The length of the slide groove 103 can be changed by adjusting the fitting length of the fixed section 1021 and the telescopic section 1022. The positioning structure 1 allows the device to be securely fitted onto a cigarette packaging box. A tension spring is fixedly installed on the telescopic section 1022, and the tension spring is connected to the fixed section 1021.

[0025] The blade holder 203 includes an n-shaped slide 2031 that is slidably mounted on the telescopic arm 202. The n-shaped cavity is fitted onto the telescopic arm 202. A protrusion 2032 is provided on the side of the slide 2031. A blade groove 2033 is provided on the protrusion 2032 along the vertical direction. The width direction of the blade groove 2033 is perpendicular to the length direction of the telescopic arm 202. The blade 204 is disposed in the blade groove 2033. A tightening structure 205 for fixing the blade 204 is provided on the side of the protrusion 2032. By adjusting the blade length of the blade 204 extending downward from the blade groove 2033 through the tightening structure 205, a fixed depth cutting is achieved to prevent excessive cutting depth from damaging the entire pack of cigarettes inside the cigarette box.

[0026] The tightening structure 205 includes an internal threaded hole on the side of the protrusion 2032 that communicates with the blade groove 2033, a bolt in the internal threaded hole, the bolt being threaded into the internal threaded hole, and its threaded end extending into the blade groove 2033 to abut against the blade 204. By rotating the bolt, the abutment force between the bolt and the blade 204 is controlled, the blade 204 is put on and taken off, and the blade length of the blade 204 extending downward out of the blade groove 2033 is adjusted.

[0027] The telescopic arm 202 includes a sleeve 2021, an inner rod 2022, and a return spring. One end of the sleeve 2021 is fixedly connected to a slider 201, and the other end is open. The return spring is disposed inside the sleeve 2021. One end of the inner rod 2022 is fitted inside the sleeve 2021 through the opening of the sleeve 2021 and abuts against the return spring. The other end is fixedly connected to another slider 201.

[0028] The sleeve 2021 is a rectangular tube, and the inner rod 2022 is a rectangular rod. The rectangular design ensures that when the drag tool holder 203 moves, the slide table 2031 will not deflect and affect the cutting of the blade 204.

[0029] On the other side opposite to the protrusion 2032, the slide 2031 is provided with a fixing structure 206. The fixing structure 206 includes an internal threaded hole provided on the side wall of the slide 2031, a bolt threaded into the internal threaded hole, and the threaded end of the bolt extends to the cavity in the n-shape and abuts against the telescopic arm 202.

[0030] The top of the slide 2031 is equipped with a handle 207, which makes it convenient for staff to hold the handle 207 for dragging.

[0031] The telescopic beam 101 includes a beam frame 1011 and a beam rod 1012. One end of the beam frame 1011 is fitted onto the beam rod 1012 and is slidably connected to the beam rod 1012. The other ends of the beam frame 1011 and the beam rod 1012 are respectively connected to a positioning beam 102. The beam frame 1011 is provided with a locking structure 3, which is used to lock the beam frame 1011 and the beam rod 1012 after adjusting the sliding connection length. The locking structure 3 includes an internal threaded hole provided on the side wall of the beam frame 1011, a bolt threaded into the internal threaded hole, and the threaded end of the bolt extending into the beam frame 1011 and abutting against the beam rod 1012.

[0032] Limiting strips 4 are provided on the outer side of the bottom of the two positioning beams 102 near the end of the telescopic beam 101, and on the far side of the bottom of the two positioning beams 102 away from the end of the telescopic beam 101. When the positioning structure 1 is pulled open and fitted onto the cigarette packaging box by setting the limiting strips 4, the limiting strips 4 can block the side of the cigarette packaging box to prevent the positioning structure 1 from moving and affecting the cutting depth accuracy of the blade 204.

[0033] Working principle: The user adjusts the telescopic beam 101 to the same width as the cigarette packaging box to be unpacked as needed and locks it through the locking structure 3. The sleeve 2021 and inner rod 2022 of the telescopic arm 202 simultaneously change their telescopic length. Then, the limiting strip 4 at the end of the two positioning beams 102 away from the telescopic beam 101 is placed on one side of the cigarette packaging box and pulled towards the user. The fixed section 1021 and the telescopic section 1022 are subjected to force and change their overlapping length, so that the slide 103 is consistent with the width of the cigarette packaging box. This allows the entire positioning structure 1 to be engaged with the top of the cigarette packaging box through the limiting strip 4. The moving cutting structure 2 is attached to the telescopic beam 101. Then, the knife holder 203 is moved on the telescopic arm 202 to the cigarette pack. At the sealing tape of the packing box, align the blade with the center seam of the sealing tape. Adjust the blade length of the blade 204 extending downward from the blade groove 2033 by tightening the screw mechanism 205. Tighten and secure the blade when it touches and punctures the sealing tape. Then, the user holds the telescopic beam 101 with one hand and the handle 207 with the other to drag it. The cutting structure 2 is restricted by the length direction of the slide groove 103 and moves along the direction of the slide groove 103. The blade completes a fixed-depth cut on the sealing tape of the cigarette packing box, realizing the unpacking function while ensuring that the blade moves horizontally and does not cut too deeply. This reduces the risk of damaging the entire pack of cigarettes inside the cigarette packing box, reduces the number of cigarettes that are scratched, and relatively improves economic efficiency.

[0034] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
