Description

Technical Field

[0001] The utility model belongs to the field of cigarette case opening equipment, and particularly relates to an automatic clamping device for opening special-shaped cigarette cases on a standard cigarette case opening machine. Background Art

[0002] In the field of tobacco logistics, it is necessary to open the cigarette cases of piece cigarettes and then sort the cigarette cartons. An important step in opening the cases is to push the cigarette cartons out of the cigarette cases of piece cigarettes so that the cigarette cartons can be sent to the sorting equipment for sorting.

[0003] At present, the standard cigarette case opening machines used in the commercial tobacco logistics industry can only open the cases of standard piece cigarettes and cannot open the cases of special-shaped cigarette cases. The main reason is that: generally, the sizes of the cigarette cases of various brands of standard piece cigarettes are relatively close, while the sizes of the cigarette cases of various brands of special-shaped cigarettes vary greatly and the widths are different. If the special-shaped cigarettes are pushed out after the cases are opened, because the widths of most special-shaped cigarettes are narrower than those of standard cigarettes, the special-shaped cigarettes are prone to collapse.

[0004] Therefore, we propose an automatic clamping device for opening special-shaped cigarette cases on a standard cigarette case opening machine to solve the above problems. Summary of the Utility Model

[0005] Aiming at the problem that the standard cigarette case opening machines used in the current commercial tobacco logistics industry can only open the cases of standard piece cigarettes and cannot open the cases of special-shaped cigarette cases.

Detailed Description of the Preferred Embodiment

[0028] The present utility model will be further described below with reference to the drawings and embodiments.

[0029] Please refer to Figures 1-3 , the present utility model provides a technical solution for an automatic clamping and holding device for opening special-shaped cigarettes on a standard cigarette unpacking machine:

[0030] Embodiment 1:

[0031] According to Figures 1-3 shown, it includes a cigarette pushing mechanism 1, a main frame body, a cigarette clamping mechanism, an auxiliary frame body, a strip cigarette sorting mechanism, a roller conveyor 3 and a belt conveyor 9.

[0032] The main frame body includes two groups of parallel rectangular frames 21. Between the two groups of rectangular frames 21, two lower connecting rods 22 and two upper connecting rods 23 are installed. Between the two upper connecting rods 23, a mounting rod 24 is installed.

[0033] The cigarette pushing mechanism 1 is located at the left end of the main frame body and is installed on the two lower connecting rods 22. The cigarette pushing mechanism 1 is a prior art, which mainly makes a linear motion and is responsible for pushing the cigarette stack out of the cigarettes. For the specific structure, reference can be made to Chinese Patent No. 2023222225492. In this embodiment, the specific structure of the cigarette pushing mechanism 1 will not be described in detail.

[0034] The roller conveyor 3 is installed on the two lower connecting rods 22 and is located on the right side of the cigarette pushing mechanism 1. The roller conveyor 3 conveys the cigarettes.

[0035] The cigarette clamping mechanism is located above the roller conveyor 3 and includes a multi-axis cylinder 42, a pressing plate 45, a driving assembly, and two sets of cigarette clamping plates 41. The multi-axis cylinder 42 is installed on the mounting rod 24, and a lifting seat 47 is installed at its bottom end. By controlling the expansion and contraction of the multi-axis cylinder 42, the lifting seat 47 is driven to move up and down.

[0036] The driving assembly is two sets of clamping cylinders 43 installed at the bottom of the lifting seat 47. The telescopic ends of the two sets of clamping cylinders 43 are arranged in opposite directions. The telescopic ends of the clamping cylinders 43 and the cigarette clamping plates 41 are detachably connected through connectors 46. By controlling the synchronous extension or contraction of the two sets of clamping cylinders 43, the two sets of cigarette clamping plates 41 can be driven to move away from or close to each other.

[0037] Multiple fixing rods 44 are installed between the pressing plate 45 and the lifting seat 47, so that the lifting seat 47 can drive the pressing plate 45 to move up and down during the up and down movement.

[0038] The auxiliary frame body includes a support frame 52 and two parallel installation beams 51. The two installation beams 51 are fixedly installed in the right rectangular frame 21, and the support frame 52 is installed at the right ends of the two installation beams 51.

[0039] Two vertical rods 53 are installed at the top of the installation beam 51, and a cross beam 54 is installed between the two vertical rods 53.

[0040] The belt conveyor 9 is installed between the two installation beams 51 and is used to receive the pushed cigarette carton stacks and convey the cigarette carton stacks.

[0041] The cigarette sorting mechanism includes two sets of fixed seats 81 and two sets of symmetrically arranged sorting clamping plates 83. The two sets of fixed seats 81 are respectively installed on the opposite sides of the two installation beams 51. An electric push rod 82 is installed on the fixed seat 81, and the telescopic end of the electric push rod 82 is fixedly connected to the sorting clamping plate 83. By controlling the extension of the two sets of electric push rods 82, the two sets of sorting clamping plates 83 are made to approach each other, and then the cigarette carton stacks on the belt conveyor 9 are sorted. After the sorting is completed, the cigarette carton stacks are conveyed by the belt conveyor 9, thereby solving the problem that the standard cigarette unpacking machine cannot unpack special-shaped cigarettes, avoiding the problem of easy stack dispersion after unpacking special-shaped cigarettes, increasing the automatic sorting variety ratio of the standard cigarette unpacking machine, and improving the overall sorting efficiency of the equipment.

[0042] Guide plates 7 are respectively arranged on both sides of the sorting clamping plate 83. The guide plates 7 are fixedly installed at the top of the installation beam 51. By providing the guide plates 7, the cigarette carton stacks can be guided to prevent the cigarette carton stacks from falling out of the belt conveyor 9.

[0043] During specific use, for the automatic clamping device for opening special-shaped cigarettes on a standard cigarette case opening machine of the present utility model, first, the cigarette cartons are conveyed to the roller conveyor 3, and then the multi-axis cylinder 42 is controlled to extend, so that the lifting seat 47, the pressing plate 45 and the two groups of cigarette clamping plates 41 move downward. When the pressing plate 45 contacts the cigarette cartons, the synchronous contraction of the two groups of clamping cylinders 43 is controlled, so that the two groups of cigarette clamping plates 41 approach each other to clamp the cigarette cartons.

[0044] Then, the cigarette stack pushing mechanism 1 pushes the cigarette stack from the cigarette cartons onto the belt conveyor 9. After that, the extension of the two groups of electric push rods 82 is controlled, so that the two groups of sorting clamping plates 83 approach each other to sort the cigarette stack on the belt conveyor 9. Finally, after the sorting is completed, the belt conveyor 9 conveys the cigarette stack.

[0045] Embodiment 2:

[0046] On the basis of Embodiment 1, as Figure 1 and Figure 2 shown, it further includes a connecting seat 61 and a baffle 64. The connecting seat 61 is fixedly installed on the tops of the two cross beams 54. A hydraulic rod 62 is installed on the top of the connecting seat 61. The telescopic end of the hydraulic rod 62 passes through the connecting seat 61 and is fixedly connected to the baffle 64. The baffle 64 is located between the two groups of guide plates 7. By controlling the extension of the hydraulic rod 62, the baffle 64 moves downward, so that the cigarette stack stays temporarily on the belt conveyor 9 and waits to enter the next process.

[0047] Two sliding sleeves are installed on the top of the connecting seat 61. A guide rod 63 is arranged inside the sliding sleeves. The bottom end of the guide rod 63 is fixedly connected to the baffle 64.
