[0039] The present disclosure will be described below with reference to the accompanying drawings, wherein the accompanying drawings illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in a variety of different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present disclosure more complete and fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0040] See also Figure 1a , 1b , showing a side flip cover cigarette box 1, wherein Figure 1a The side flip cover cigarette box 1 is shown in a closed state, and the suction cup 5 is shown. Figure 1b The side flip cover cigarette box 1 is shown in an open state. The side flip cover cigarette box 1 mainly comprises two parts hinged together: an upper flip cover 2 and a lower flip cover 3, wherein the lower flip cover comprises a receiving portion 4 for receiving a certain number of cigarettes (not shown).

[0041] On the tobacco packaging production line, when the side flip cover cigarette box 1 is conveyed from the cigarette box hopper (not shown) to the flip cover station by the conveyor belt in the closed state, the side flip cover cigarette box 1 is clamped in a fixed cigarette box conveying channel (not shown) and Figure 2 The side flip cover cigarette box 1 is then clamped by a plurality of suction cups 5 (see FIG. Figure 1a ) Use negative pressure suction to suck the upper flip cover 2 upward and open it, so that a single liner paper, cigarette sticks and other raw and auxiliary materials can be filled in, and the next packaging process can be carried out.

[0042] See also Figure 2, showing an exploded view of a bearing clamping device 6 of the prior art. The bearing clamping device 6 comprises a plurality of bearings 67 capable of horizontal reciprocating motion, and the reciprocating motion of the bearings 67 is for better clamping the side flip cover cigarette box 1. The bearing 67 is mounted on a T-shaped mounting seat 64 through an eccentric pin 68 and a nut 63, and the mounting seat 64 is mounted on the first end of a support link 65 through a nut 61 and a gasket 62. The middle part of the support link 65 is pivotally mounted to the clamping base 66 through a pivot (not shown), and the clamping base 66 is fixed. The second end of the support link 65 opposite to the first end can swing through a roller, a connecting rod, a rocker or other device (not shown), and the swinging motion is transmitted to the first end of the support link 65 with the pivot as the center point, and is transmitted to the plurality of bearings 67 through the mounting seat 64. The bearing clamping device 6 can enable the multiple bearings 67 to reach the best clamping position of the lower flip cover 3 of the side flip cover cigarette box 1 through horizontal reciprocating motion, thereby facilitating the suction cup 5 to open the upper flip cover 3 from above.

[0043] In the bearing clamping device 6 according to the prior art, a plurality of columnar bearings 67 are engaged with the side of the lower flap 3 of the side-flap cigarette box 1, so the contact between the bearing 67 and the side of the cigarette box is a relatively short line contact. Such a short line contact cannot achieve a large friction force. Therefore, as mentioned above, in daily production in the workshop, the suction cup often sucks the entire side-flap cigarette box upward, or the side-flap cigarette box flap is not fully opened, resulting in equipment shutdown, seriously affecting the equipment production efficiency, causing abnormal consumption of the side-flap cigarette box, and increasing production costs.

[0044] In order to solve the problem of insufficient clamping force, the present application provides a packaging box clamping device, which clamps the side of the cigarette box by surface contact, and the surface contact is replaced by the clamping strip 7 according to the present application. Figure 2 The bearing 67 shown in FIG. 6 is realized, and the packaging box clamping device according to the present application also includes a device for mounting the clamping strip 7 to the Figure 2 The clamping strip seat 8 on the mounting seat 64 shown below refers to Figure 3-9 Detailed description. Figure 3 , 4 A perspective view and a side view of the clamping strip 7 are shown respectively, Figure 5-7 The clamping strip seat 8 is shown in a perspective view, a side view and a top view. Figure 8 , 9 A perspective view and a side view are shown of the assembled clamping strip 7 and the clamping strip carrier 8 .

[0045] See also Figure 3 , 4According to the present application, the clamping strip 7 is in the shape of a long strip as a whole, and includes a contact surface 71 that is in direct contact with the surface of the packaging box. The contact surface 71 can generate a large friction force when pressed against the side surface of the cigarette box. For example, the clamping strip 7 can be made of a flexible or elastic material that can generate a large friction force, such as rubber, and preferably can also include a molded surface that can increase the friction force, or the contact surface 71 can be appropriately surface treated to increase the friction force. Preferably, referring to Figure 3 , 4 The contact surface 71 of the clamping strip 7 includes a plurality of concave and convex stripes 72, and the stripes 72 are arranged along the height direction of the clamping strip 7 ( Figure 3 , 4 , 8, 9) extend in the up-down direction. Preferably, the plurality of concave-convex stripes 72 are evenly distributed in the width direction of the clamping strip 7. Preferably, although not shown, it is conceivable to perform surface treatment on the contact surface 71 of the clamping strip 7 to increase its friction, for example, when the clamping strip 7 is made of metal or plastic material, spray a rubber layer on the contact surface 71.

[0046] From the above description, it can be seen that the clamping strip 7 according to the present application can make surface contact with the surface of the packaging box to be clamped. Therefore, compared with the multiple short-line contacts through bearings in the prior art, the packaging box clamping device of the present application can apply a greater clamping force to the packaging box.

[0047] See also Figure 5-7 In order to facilitate the installation of the clamping strip 7 on the packaging box clamping device according to the present application, the packaging box clamping device may further include a clamping strip seat 8, which is generally in the shape of a rectangular parallelepiped and includes a step 81 and at least one threaded hole 82. The clamping strip seat 8 may be made of any rigid material, and is used to install the clamping strip 7 to the mounting seat 64 (see Figure 1) of the packaging box clamping device. For example, the clamping strip 7 is fixed to the clamping strip seat 8 by gluing, and the adhesive may be applied to the contact surface between the clamping strip 7 and the clamping strip seat 8. Preferably, the length of the clamping strip seat 8 is approximately equal to the corresponding length of the mounting seat 64 of the packaging box clamping device, and is approximately equal to the length of the clamping strip 7. The step 81 is used to limit the upward movement of the clamping strip 7, and the step 81 is set at a height h (see Figure 1) from the bottom surface of the clamping strip seat 8. Figure 5 , 6), preferably, the height h is substantially equal to the height of the clamping strip 7, so that when the clamping strip 7 is assembled into the clamping strip seat 8, the bottom surface of the clamping strip 7 is substantially flush with the bottom surface of the clamping strip seat 8. The threaded hole 82 is used to mount the clamping strip seat 8 to the mounting seat 64 by screws. Preferably, the clamping strip seat 8 includes two threaded holes 82, and when the clamping strip seat 8 is mounted on the mounting seat 64, the two threaded holes are aligned with the two threaded holes on the mounting seat 64, so that the clamping strip seat 8 can be fixed to the mounting seat 64 by screws. Preferably, the diameter of the threaded hole 82 is larger than the screw that cooperates therewith, so that the relative position between the clamping strip seat 8 and the mounting seat 64 can be fine-tuned in the front-to-back and left-to-right directions. Preferably, a spacer, such as a nut (not shown), can be provided between the mounting seat 64 and the clamping bar seat 8 to adjust the height of the clamping bar 7 mounted on the clamping bar seat 8 so that the contact surface 71 of the clamping bar 7 can fully overlap with the surface of the packaging box to be clamped so as to clamp the packaging box.

[0048] Figure 8 and 9 The clamping strip 7 is shown mounted on the clamping strip seat 8, see Figure 8 The thickness of the clamping strip 7 is greater than the depth of the step 81 of the clamping strip seat 8, so that in the assembled state, the contact surface 71 of the clamping strip 7 protrudes from the clamping strip seat 8 so as to contact the packaging box to be clamped. When the clamping strip 7 abuts against and clamps the side surface of the lower flip cover 3 of the side flip cover cigarette box 1, the suction cup 5 is adsorbed on the outer surface of the upper flip cover 2 of the side flip cover cigarette box 1, thereby opening the upper flip cover 2 from above. At this time, the clamping strip 7 is subjected to an upward force, and the step 81 of the clamping strip seat 8 can prevent the clamping strip 7 from moving upward, which is conducive to the clamping strip 7 to keep clamping the side flip cover cigarette box 1.

[0049] It is conceivable to omit the clamping strip seat 8, and directly fix the clamping strip 7, for example, made of a rubber material, on the mounting seat 64 of the packaging box clamping device according to the present application. Alternatively, the clamping strip 7 is made of a rigid material, and the contact surface 71 of the clamping strip 7 is subjected to a surface treatment to increase the friction, for example, a layer of rubber is sprayed on the contact surface 71, or the clamping strip seat 8 can be omitted. In the case where the clamping strip seat 8 is omitted, a mounting hole is provided on the clamping strip 7 so as to cooperate with the mounting hole on the mounting seat 64, and the size of the clamping strip 7 itself can be set, or the height of the contact surface 71 can be set by an appropriate spacer, so that the contact surface 71 can fully contact the surface of the packaging box to be clamped.

[0050] The packaging box clamping device according to the present application may include: a fixed clamping base 66; a supporting link 65, which is connected to the clamping base 66 by a pivot at its middle part, the first end of the supporting link 65 located on one side of the pivot is accommodated in a groove of the clamping base 66, the first end can be driven to perform reciprocating pivotal motion in the groove, and the second end of the supporting link 65 located on the other side of the pivot and opposite to the first end can perform pivotal motion around the pivot under the drive of the first end; a mounting seat 64, which is fixed to the second end of the supporting link 65 and can reciprocate with the pivotal motion of the second end; a clamping bar seat 8, which is fixed to the mounting seat 64 and can reciprocate with the mounting seat 64; and a clamping bar 7, which is fixed to the clamping bar seat 8 and has a contact surface 71, which protrudes from the clamping bar seat and can contact the surface of the packaging box to be clamped.

[0051] As mentioned above, the clamping bar seat 8 can be omitted.

[0052] Therefore, the clamping strip 7 can reciprocate, and through the reciprocating motion, the clamping strip 7 contacts and clamps the lower flip cover 3 of the side flip cover cigarette box, and then the upper flip cover 2 is sucked upward and opened by the suction cup 5 above. The clamping strip 7 is made of a material with a large friction coefficient such as rubber, which can generate a large clamping force to ensure that the box cover is not sucked open properly or the entire cigarette box is sucked upward, which provides a guarantee for the stable operation of the equipment. And as can be seen from the above, the packaging box clamping device according to the present application has a simple structure, is easy to install, and has a low cost.

[0053] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence.
