Description

Technical Field

[0001] The utility model relates to a side-opening cigarette box opening device, belonging to the technical field of cigarette packaging. Background Art

[0002] The side-opening cigarette box is a common cigarette box, which is briefly described as follows: Figure 1 As shown, it consists of a box body 101 and a box cover 102. The box body is provided with a cigarette storage cavity 105 for accommodating cigarettes. The box cover 102 can rotate around one side of the box body 101 in the width direction, so as to adopt a side opening method of the box cover. A decorative cover paper 103 is provided on the opening surface of the box body 101.

[0003] When packing cigarettes, the cigarette boxes are transported to the designated workstation by the cigarette box conveying device. Before the cigarette box-putting device puts the cigarettes into the empty cigarette box, the box lid and the cover paper inside the cigarette box need to be opened. Since the box lid itself has a certain elasticity and the cover paper will automatically rebound, some cigarette boxes will be opened and cigarettes will be stuck during the cigarette putting process, causing damage to the cigarette box or the cover paper. Summary of the invention

[0007] The cover paper opening mechanism includes a second opening and closing rod and a second driving mechanism that drives the second opening and closing rod to move. The end of the second opening and closing rod is provided with a second suction nozzle that cooperates with the cover paper. The frame is provided with a paper blocking piece extending along the movement direction of the cigarette box conveying device; the second suction nozzle drives the cover paper to make it have a paper blocking state located below the paper blocking piece.

[0008] The utility model provides an elastic box cover baffle and a paper baffle, firstly the box cover is kept in an open state by the elastic box cover baffle, and then the flexibility of the cover paper is used to ensure that the box cover and the cover paper are in an open state. The utility model is cleverly arranged, and the cigarette box and the cover paper can be opened smoothly. Moreover, the paper baffle extends along the moving direction of the cigarette box conveying device, which can ensure that the cigarette box will not be stuck in the subsequent movement process, thereby avoiding damage to the cigarette box or the cover paper during the process of cigarettes being put into the box.

DETAILED DESCRIPTION

[0014] The side-opening cigarette box opening device of this embodiment is as follows: Figure 2 and Figure 3 As shown, it includes a frame 1, a box cover opening mechanism 501 and a cover paper opening mechanism 510. The frame 1 is provided with a cigarette box conveying device 500. The specific structure of the cigarette box conveying device 500 is not limited. In this embodiment, a turntable cigarette box conveying device is adopted. A plurality of cigarette box fixing mechanisms 104 are provided on the cigarette box conveying device 500, so that the cigarette boxes 100 are transferred between various stations of the cigarette box conveying device 500. The box cover opening mechanism 501 and the cover paper opening mechanism 510 are arranged on different stations of the cigarette box conveying device 500. When in use, the box cover 102 is opened first, and then the cover paper 103 is opened.

[0015] The box cover opening mechanism 501 includes a first opening and closing rod 507 and a first driving mechanism for driving the first opening and closing rod 507 to move, the end of the first opening and closing rod 507 is provided with a first suction nozzle 506 that cooperates with the box cover 102, and the frame 1 is provided with an elastic box cover baffle 502; the first suction nozzle 506 drives the box cover 102 to make it have a box blocking state located below the elastic box cover baffle 502. In the initial state, the box cover 102 is in contact with the box body 101, and the first suction nozzle 506 is driven by the first opening and closing rod 507 to absorb the box cover 102, and the box cover 102 then rotates around the root of the cigarette box 100 to open. When opening, the box cover 102 breaks the restraint of the elastic box cover baffle 502, and the elastic box cover baffle 502 can rotate around the opening and closing rod at a certain angle to adapt to the elastic force of the box cover 102. After opening in place, the first suction nozzle 506 is released to separate from the box cover 102, and the box cover 102 moves in the opposite direction to the elastic box cover baffle 502. Since the box cover 102 has a certain rigidity and has resilience after opening, the opened and rebounded box cover 102 contacts the elastic box cover baffle 502 to keep the box cover 102 in an open state. It can be seen that the opening process of the box cover 102 is the process of the elastic box cover baffle 502 swinging back and forth.

[0016] Preferably, a first arc-shaped transition guide 505 is provided at the end of the elastic box cover baffle 502 close to the first suction nozzle 506, and its arc-shaped structure ensures that the elastic box cover baffle 502 is not caught during the movement of the box cover 102.

[0017] In addition, the frame 1 may also be provided with a spring for resetting the elastic cover baffle 502, and the spring may prevent the elastic cover baffle 502 from oscillating back and forth when returning to its original position, thereby affecting the next opening of the cover 102. In order to limit the travel of the elastic cover baffle 502 and prevent it from moving too much, the frame 1 is provided with a limit block 503, and a waist-shaped hole may be provided on the elastic cover baffle 502, and the limit block 503 is inserted into the waist-shaped hole, so that the swing amplitude of the elastic cover baffle 502 is controlled by the limit block 503.

[0018] After the box cover 102 is opened by the box cover opening mechanism 501 , it continues to move to the next station, and the cover paper 103 is opened by the cover paper opening mechanism 510 .

[0019] like Figure 2 and Figure 3As shown, the cover paper opening mechanism 510 includes a second opening and closing rod 513 and a second driving mechanism driving the second opening and closing rod 513 to move, the end of the second opening and closing rod 513 is provided with a second suction nozzle 512 matched with the cover paper 103, and the frame 1 is provided with a paper stopper 511 extending along the moving direction of the cigarette box 100 conveying device; the second suction nozzle 512 drives the cover paper 103 to have a paper stopper state located below the paper stopper 511. Preferably, the end of the paper stopper 511 close to the second suction nozzle 512 is provided with a second arc-shaped transition guide.

[0020] The second driving mechanism controls the movement of the opening and closing rod so that the second suction nozzle 512 touches the surface of the cover paper 103, and then the negative pressure generated connects the second suction nozzle 512 with the cover paper 103, and the cover paper 103 rotates around the root of the cigarette box 100 to open. After the cover paper 103 is opened into place, the negative pressure releases the second suction nozzle 512 and separates it from the cover paper 103, and the cigarette box 100 continues to move to the paper baffle 511. Since the cover paper 103 is flexible, it can ensure that the box cover 102 and the cover paper 103 can pass normally after opening, thereby completing the opening of the cigarette box 100 and preparing for the subsequent cigarettes to be put into the box.

[0021] The first driving mechanism and the second driving mechanism have multiple implementation modes, which are prior art and are not limited to this. In this embodiment, the first driving mechanism and the second driving mechanism both use rotary cylinders.
