Description

Technical Field

[0001] The utility model relates to the technical field of equipment for cigarette production, in particular to a device for grabbing cut tobacco. Background Art

[0002] Cut width refers to the width of the tobacco leaves formed by the cutter after the tobacco leaves are added. Cut width directly affects the intrinsic quality of the cigarette product. Controlling the quality and size of the cut tobacco is key to ensuring the consistency of the product's taste and appearance. Therefore, sampling and testing of cut tobacco is particularly important. The cut width pass rate is a key indicator in the quality management evaluation of the tobacco production line process. Tobacco with an appropriate width has better filling capacity, resulting in a fuller and smoother cigarette. However, uneven cut width will result in a lower whole tobacco rate and an increased broken tobacco rate, which will also increase cigarette consumption.

[0003] When measuring the width of the cut tobacco, it is necessary to first sample the cut tobacco after it has been cut by the cutter, and then perform a width test. At present, the sampling method for cut tobacco is generally manual sampling, that is, the inspector randomly grabs a sample of about 50 grams of cut tobacco at the outlet of the cutter and places it in a sample box. The sample box is then sent into the inspection room, and 150-200 tobacco leaves are randomly selected from the sample box and the width of the leaf is measured in accordance with the requirements of the "Cigarette Process Specifications". The defects of this manual sampling method are: it is impossible to achieve online sampling, the sampling accuracy and efficiency are low, and it is difficult to ensure the purity and integrity of the sampled samples.

[0017] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0018] See also Figures 1 to 3 This embodiment discloses a post-cut tobacco grabbing device, comprising a base 1, a vertically movable grabbing plate 2 disposed on the base 1, and a plurality of grabbing hooks 3 disposed at the bottom of the grabbing plate 2. The grabbing hooks 3 are arranged in three rows along the front-to-back direction at the bottom of the grabbing plate 2, with the grabbing hooks 3 in each row spaced apart along the left-to-right direction. The claws at the bottom of the grabbing hooks 3 extend rearward, and a first driving mechanism drives the grabbing plate 2 to rise and fall vertically, causing the grabbing hooks 3 at the bottom of the grabbing plate 2 to retract upward into the base 1 or extend downward below the base 1. A guide cavity is defined in the base 1 for guiding the vertical sliding of the grabbing plate 2. A mounting plate 5 is disposed above the base 1 via two U-shaped frames 4. The first driving mechanism is a cylinder 6, the cylinder body of which is mounted at the bottom of the mounting plate 5. The piston rod of the cylinder 6 extends vertically downward and is connected to the top of the grabbing plate 2, driving the grabbing plate 2 to rise and fall vertically via the cylinder 6.

[0019] A blowing assembly is provided at the front side of the bottom of the base 1. Positive pressure air is ejected through the blowing port 7 of the blowing assembly, thereby blowing the tobacco shreds caught on the multiple grab hooks 3 of the grab plate 2 backward. The blowing assembly includes two blowing blocks 8 arranged side by side on the left and right. The blowing blocks 8 are hollow and flat. The internal cavity of the blowing blocks 8 forms a blowing channel. The blowing channel is a channel with a narrowed front end and an open rear end. The front end of the blowing channel of the blowing block 8 is connected to an air pipe 9, which is provided with an air valve 10, and an external air source is connected through the air pipe 9.

[0020] An elastic bracket is provided on top of the mounting plate 5. The elastic bracket comprises an upper bracket plate 14 and a lower bracket plate 11 arranged vertically. The bottom of the lower bracket plate 11 is connected to the mounting plate 5. The two bracket plates are connected by at least two bolts 12. Each bolt 12 passes through both bracket plates and is screwed onto a nut 15 to lock the two bracket plates together. Each bolt 12 is fitted with a spring 13, which is located between the two bracket plates. During the post-cut tobacco sampling process, the vibration of the discharge trough at the discharge end of the cutter may interfere with or even damage the gripping device. The provision of the elastic bracket acts as an elastic buffer for the gripping device during the sampling process, effectively protecting the gripping device from damage.

[0021] When working, the grabbing device can be connected to the robotic arm through the upper support plate 14 of the elastic support, and the robotic arm drives the grabbing device to move to achieve online automatic sampling. The specific operation process is as follows:

[0022] The gripping device is driven by a robotic arm to the top of the discharge trough at the discharge end of the shredder. The cylinder 6 is activated to drive the gripping plate 2 downward so that it extends downward to below the base 1, so that the multiple gripping hooks 3 at the bottom of the gripping plate 2 are inserted into the cut tobacco conveyed on the discharge trough. The cut tobacco moves with the vibration of the discharge trough and is hooked on the claws of the multiple gripping hooks 3 for sampling. After the sampling is completed, the gripping device is lifted away from the discharge trough and brought to the detection station by the robotic arm. Then the blowing assembly is started, and the air valves 10 corresponding to the two blowing blocks 8 are opened, connecting to the positive pressure air source. Positive pressure air is blown backward from the blowing channels of the two blowing blocks 8, thereby blowing the tobacco hanging on the multiple gripping hooks 3 at the bottom of the gripping plate 2 backward and falling into the detection station, and then the width of the cut tobacco can be measured.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
