[0001] This utility model belongs to the field of tobacco production technology, specifically relating to an auxiliary device for a box-holding machine. Background Technology

[0002] With the development of the industry, the tobacco sector has been continuously promoting cost reduction and efficiency improvement, leading to an increasing number of reusable cigarette boxes. However, the use of reusable cigarette boxes has also brought about various problems. Cigarette boxes are made of corrugated cardboard and inner and outer paper. During the use of reusable cigarette boxes, it was found that they are weaker than new boxes. The creases on the flaps soften after folding, reducing support and causing a significant increase in the number of downtime and malfunctions of the box-sealing machine. This also affects the operating efficiency of upstream equipment.

[0003] When the cigarette box is flared, the upper flap cannot be supported and droops after conventional flaring, which causes blockage when the cigarettes enter the box, resulting in quality defects and machine malfunctions. In addition, the cigarette box is also prone to puncture during subsequent sealing.

[0004] Therefore, how to design an auxiliary device for the box-sealing machine to support the upper flap of the circulating cigarette box and prevent it from sagging, thereby reducing the probability of the box-sealing machine malfunctioning and stopping, has become a technical problem that urgently needs to be solved by those skilled in the art.

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] like Figures 1 to 3 As shown, this utility model embodiment provides an auxiliary device for a box-holding machine, which includes a base, a fixed support plate 21, a torsion spring 51, a rotating shaft 41, and a box-holding baffle 31 for supporting the upper flap of a circulating cigarette box. The base is mounted on the crossbeam 61 of the box-holding machine and is located opposite the box-holding device. The fixed support plate 21 is vertically mounted on the base. The right end of the box-holding baffle 31 is rotatably connected to the upper end of the fixed support plate 21 via the rotating shaft 41, and the rotating shaft 41 is parallel to the crossbeam 61. The torsion spring 51 is fitted onto the rotating shaft 41, and the two ends of the torsion spring 51 are respectively mounted on the box-holding baffle 31 and the fixed support plate 21, making the box-holding baffle 31 perpendicular to the fixed support plate 21.

[0028] The auxiliary device for the box-sealing machine provided in this embodiment of the utility model uses the box-sealing baffle 31 to support the upper flap of the circulating cigarette box. This supports the upper flap of the circulating cigarette box and prevents it from sagging due to the softness of the crease. Consequently, it prevents the cigarette packs from becoming clogged when entering the cigarette box, thus reducing the probability of the box-sealing machine malfunctioning and stopping.

[0029] Furthermore, the base includes a base plate 11 and a fixing block 12. The right end of the base plate 11 is connected to the crossbeam 61. A through hole 13 is provided on the base plate 11. The fixing block is disposed on the bottom surface of the base plate and opposite to the through hole. The lower end of the fixing support plate passes through the through hole 13 and is connected to the fixing block 12. This design, by inserting the fixing support plate into the through hole and then connecting it to the fixing block, provides more stable and reliable support for the fixing support plate.

[0030] Specifically, the fixing block 12 is bolted to the base plate 11; the base plate 11 is detachably connected to the crossbeam 61, thereby facilitating the replacement or maintenance of the base plate, fixing support plate, and fixing block. It is understood that the base plate 11 and the crossbeam 61 can also be bolted together; the two ends of the torsion spring are respectively disposed on the support box baffle and the fixing support plate, with the support box baffle perpendicular to the fixing support plate, i.e., the torsion spring is a 90° torsion spring.

[0031] Preferably, the perforation 13 is located in the middle of the base plate 11.

[0032] Furthermore, both the upper end of the fixed support plate 21 and the right end of the support box baffle 31 are U-shaped structures 71. With this design, during installation, the U-shaped structure at the right end of the support box baffle can be placed within the U-shaped structure at the upper end of the fixed support plate, and then the rotating shaft can pass through the side plates of these two U-shaped structures. A torsion spring is fitted onto the rotating shaft and located within the U-shaped structure at the upper end of the fixed support plate.

[0033] Preferably, limit blocks 42 are provided at both ends of the rotating shaft 41, so as to better prevent the rotating shaft from coming off.

[0034] Specifically, the support baffle 31 is a rectangular plate, and the left corner of the support baffle 31 is rounded, which can better prevent the support baffle 31 from scratching the circulating cigarette box.

[0035] This utility model's auxiliary device for the box-sealing machine has a simple structure, is not easily damaged, has low maintenance costs, and requires no other power equipment, reducing energy consumption. Furthermore, since this device is installed on the box-sealing machine by drilling holes in existing equipment, installation is simple and convenient, offering high practical value and significantly reducing modification costs. Moreover, because the fixed support plate and the box-sealing baffle are at a 90° angle (perpendicular) under the action of a torsion spring, the angle between them changes when the baffle is subjected to external force. This prevents damage to the cigarette box during operation, thus improving the reusability of the circulating cigarette box. This utility model can support the upper flap of the circulating cigarette box to be sealed, preventing blockages and quality defects caused by cigarette packs entering the box during the packing process. It also reduces the probability of machine malfunction and downtime, increasing the utilization rate of the circulating cigarette box, and has strong promotional value in the tobacco industry and other related industries.

[0036] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
