Description

Technical Field

[0001] The utility model relates to a device suitable for conveying cigarette strips of various specifications. Background Art

[0002] Before cigarette cartons are sent to various sales stores, different types of cigarette cartons need to be laminated and packaged together according to the needs of the stores. Before being transported to the packaging station, the cigarette cartons need to be clamped and transported one by one by a conveyor belt, so that they can be better stacked in the cigarette cartons stacking mechanism for subsequent lamination and packaging. Since cigarette cartons have standard and special-shaped models (special-shaped models have a variety of sizes, but the sizes are smaller than standard cigarette cartons), if the distance between the clamping and conveying mechanisms is adjusted to match the thickness of the special-shaped cigarette cartons, standard cigarette cartons will not be able to be transported; if the spacing of the clamping and conveying mechanisms is adjusted to match the thickness of standard cigarette cartons, although the special-shaped cigarette cartons can be input, the special-shaped cigarette cartons cannot be pushed forward quickly to enter the cigarette cartons stacking mechanism. For this reason, a device that can be used for the transportation of cigarette cartons of various specifications is needed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0020] refer to Figures 1 to 3

[0021] A device suitable for conveying cigarette strips of various specifications comprises a frame, on which an output conveyor belt 10 driven to rotate by a driving mechanism is transversely arranged, a clamping conveyor belt 20 capable of being raised and lowered is arranged on the upper side of the output conveyor belt, a limited height baffle 30 is arranged on the rear side of the input end of the clamping conveyor belt, an input conveyor belt 40 driven to rotate by another driving mechanism is arranged on the rear side of the input end of the output conveyor belt, and a cigarette pressing plate 50 capable of being raised and lowered is arranged on the upper side of the output end of the input conveyor belt.

[0022] In this embodiment, a connecting seat 22 is installed on the fixed frame 21 of the pinch conveyor belt, and the connecting seat is vertically slidably connected to a gantry 23 straddling the upper side of the output conveyor belt. Both sides of the connecting seat are slidably connected to the gantry via vertically arranged linear guide rails 24. A first lifting cylinder 25 is vertically arranged on the gantry, and the telescopic rod of the first lifting cylinder is connected to the connecting seat. The fixed frame is driven by the first lifting cylinder to lift and lower the pinch conveyor belt.

[0023] In this embodiment, in order to drive the pinch conveyor belt to rotate, the front and rear ends of the fixed frame are respectively equipped with active rollers 26 and driven rollers 27, the active rollers are driven to rotate by a motor, and two pinch conveyor belts are wound between the active rollers and the driven rollers to ensure the pinching stability. The outer side of the pinch conveyor belt is provided with a sponge layer 28, which can ensure that the cigarette strips will not be damaged when being pinched.

[0024] In this embodiment, the height limiting baffle is arranged at the lower rear part of the pinch conveyor belt, and both sides of the height limiting baffle are fixedly connected to the rear end of the fixing frame via the connecting plate 31. The height limiting baffle is used to block cigarettes whose thickness exceeds the distance between the pinch conveyor belt and the output conveyor belt.

[0025] In this embodiment, in order to realize the lifting and lowering of the cigarette pressing plate, a mounting frame 60 is provided on the upper side of the input conveyor belt, and a second lifting cylinder 61 is vertically fixed on the mounting frame, and the lower end of the telescopic rod of the second lifting cylinder is connected to the cigarette pressing plate. After the cigarette is blocked by the height-limiting baffle, the input conveyor belt stops rotating, and the second lifting cylinder descends to press the cigarette to prevent the cigarette from continuing to be output forward.

[0026] In this embodiment, both sides of the mounting frame are fixed with an introduction guard plate 62 located on the upper side of the input conveyor belt, and the rear end of the introduction guard plate has an upwardly tilted guide portion, so that after the cigarette strips enter between the introduction guard plate and the input conveyor belt, they can be better delivered between the clamping conveyor belt and the output conveyor belt.

[0027] In this embodiment, a sponge plate 51 is fixed to the lower side of the cigarette pressing plate, which helps to prevent the cigarette cartons from being crushed.

[0028] In this embodiment, matching infrared sensors 70 are arranged above both sides of the output end of the input conveyor belt, and the installation height of the infrared sensors is less than the thickness of standard cigarettes and greater than the thickness of special-shaped cigarette strips. The infrared sensors are electrically connected to the controllers of the first lifting cylinder and the second lifting cylinder, so that when the infrared sensors just sense that the standard cigarette strips are blocked, the second lifting cylinder controls the cigarette pressing plate to descend to press the standard cigarette strips, and the first lifting cylinder drives the clamping conveyor belt to rise.

[0029] When the standard cigarettes are transported forward and blocked by the height limit baffle, the infrared sensor detects the standard cigarettes, the input conveyor belt stops rotating, and the controller controls the second lifting cylinder to descend so that the cigarette pressing plate presses the cigarettes to prevent the cigarettes from continuing to be output forward. The first lifting cylinder drives the fixed frame to raise the pinch conveyor belt (the rising height is pre-set) so that the height limit baffle will not block the standard cigarettes. The second lifting cylinder drives the cigarette pressing plate to rise, and the input conveyor belt operates, so that the standard cigarettes are fed between the pinch conveyor belt and the output conveyor belt. After the standard cigarettes are output, the pinch conveyor belt can be lowered to its original position.

[0030] If the words "first", "second" and the like are used in the above-mentioned text of the utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above-mentioned words have no special meaning.

[0031] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0032] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0033] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0034] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
