Abstract
Description
Technical Field
[0001] This application relates to the technical field of tobacco production, and in particular to cigarette feeding mechanisms. Background Technology
[0002] In existing technologies, online laser perforation devices for cigarettes are used to perforate the filter portion of the cigarette, thereby achieving accurate control of the filter's ventilation volume. However, during production, issues such as dirt on the cigarette and lenses along the laser path, or grime buildup on the laser drum and pusher wheel, can lead to problems like aperture deviations or insufficient hole counts during laser perforation. This results in excessive filter ventilation data and fluctuations in the smoking flavor. Currently, portable microscopes are used to inspect the quality of laser perforation in cigarettes, requiring manual counting, which cannot accurately quantify the aperture, resulting in low accuracy and efficiency.
[0003] Currently, the use of portable microscopes to inspect the quality of laser-drilled holes in cigarettes requires manual counting, which cannot accurately quantify the hole diameter, resulting in low accuracy and efficiency. Summary of the Invention
[0004] To overcome the aforementioned technical deficiencies, this application provides a cigarette feeding mechanism, comprising at least one of the following:
[0005] A hopper device having a V-shaped cavity and a groove at the bottom for accommodating a single cigarette, the V-shaped cavity being used to accommodate multiple cigarettes to be pushed; and
[0006] A pushing device for pushing a single cigarette along the groove.
[0007] In some embodiments, the pushing device includes a push rod that is slidable in the groove to push the cigarette along the groove;
[0008] The hopper device includes:
[0009] A front baffle and a rear baffle are arranged in parallel. The bottom of the front baffle has a front opening for the cigarette to be discharged from the front opening, and the bottom of the rear baffle has a rear opening for the push rod to pass through.
[0010] The left and right hoppers are arranged between the front and rear baffles, forming the V-shaped cavity between the left and right hoppers, and the gap between the bottoms of the left and right hoppers forms the groove.
[0011] In some embodiments, the cigarette feeding mechanism includes a stirring device arranged on the right hopper and includes a connected inclined plate and a horizontal portion. The right hopper has a vertically extending channel, and the horizontal portion passes horizontally through the channel, such that when the horizontal portion moves vertically along the channel, the inclined plate moves vertically along the inner side of the right hopper to cause one of the cigarettes to fall into the groove.
[0012] In some embodiments, the agitation device includes a first motor and an eccentric block arranged on the outside of the right hopper. The eccentric block is eccentrically driven connected to the drive shaft of the motor and abuts against the lower end of the horizontal section to push the horizontal section to move up and down, thereby driving the inclined plate to move up and down reciprocally along the inside of the right hopper.
[0013] In some embodiments, the pushing device includes a second motor, a drive belt, and a guide rail. The drive belt is fixedly connected to the push rod. The second motor drives the drive belt to cause the push rod to reciprocate along the guide rail between a push position and an initial position. In the push position, the push rod pushes the cigarette out of the front opening. In the initial position, the front end of the push rod moves to the rear opening to prepare to push the next cigarette.
[0014] In some embodiments, the pushing device includes:
[0015] A connecting rod, the upper end of which is connected to the front end of the push rod, and the drive belt is clamped in the opening groove of the connecting rod;
[0016] The marker piece is connected to the connecting rod;
[0017] A first sensor is disposed inside the front opening of the front baffle. When the marking piece is detected by the first sensor, the push rod is in the extended position; and
[0018] The second sensor is located outside the rear opening of the rear baffle. When the marker is detected by the second sensor, the push rod is in the initial position.
[0019] In some embodiments, the guide rail is provided with an elongated groove, the push rod is located above the guide rail, the connecting rod passes through the elongated groove, and the marking piece is fixed to the lower end of the connecting rod.
[0020] The cigarette feeding mechanism includes a controller for sending commands to the second motor to rotate in the reverse direction when the push rod reaches the initial position and the push-out position.
[0021] In some embodiments, the lower edge of the inclined plate is provided with elongated protrusions.
[0022] On the other hand, this application provides a tobacco production line, including the aforementioned cigarette feeding mechanism.
[0023] The cigarette feeding mechanism provided in this application can achieve at least one of the following technical effects:
[0024] The hopper device has a V-shaped cavity with a smoke groove at the bottom, allowing the cigarette stick and push rod to pass through;
[0025] The stirring device drives the inclined plate to move up and down along the right hopper, so that one of the cigarettes falls smoothly into the tobacco trough of the hopper device.
[0026] The pusher moves the push rod back and forth between the initial position and the push position through the push device. The sensor detects the marker and ensures that the push rod is fully retracted to the rear baffle of the hopper device or the push rod pushes the cigarette away from the front baffle.
