A straightening wheel with a reject function

Abstract

The application discloses a straightening wheel with a rejecting function, which is mainly adapted to the running state of a cigarette on a rolling wheel, and simply speaking, the straightening claw of the straightening wheel should be at different positions of the adsorption groove of the rolling wheel to realize two working states of straightening and placing of the cigarette and automatic rejection of the cigarette. The design idea of the application is to actively reproduce the abnormal working state of the original equipment under appropriate working conditions, and the cigarette in the abnormal state can be directly rejected, so that the use function and effect of the equipment are expanded.

Description

Technical fields:

[0001] This invention belongs to the field of tobacco processing equipment research and development technology, and specifically relates to a straightening wheel with a rejection function, also known as a return wheel. Background technology:

[0002] The cigarette punching machine is installed on the cigarette tip attaching machine. It accepts cigarettes with double-length filter tips from the cigarette rolling roller and punches holes by rotating the roller. Because models such as PROTOS-70 do not have a rejection function on their cigarette rolling roller, when the machine is first turned on, before the tipping paper is finished rolling the cigarettes, the separated filter tips and cigarettes can directly enter the cigarette slot of the cigarette rolling roller. Once the separated filter tips and cigarettes enter the cigarette inlet slot of the punching machine, the roller will not be able to make the filter tips and cigarettes rotate at the same time, resulting in a blockage. This causes the entire cigarette rolling machine to stop due to blockage.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention:

[0004] The purpose of this invention is to provide a straightening wheel that retains the existing operating state of the straightening wheel while adding an angular displacement deflection to achieve the rejection function, thereby overcoming the defects in the prior art.

[0005] To achieve the above objectives, the present invention provides a straightening wheel with a rejection function, which is assembled on the side of the working area of ​​the cigarette rubbing board and the cigarette rubbing wheel after the rubbing process is completed. It is used to straighten the cigarette after the rubbing process is completed and adsorb it into the adsorption groove of the cigarette rubbing wheel. It mainly includes a straightening wheel with straightening claws on it. The rotational linear speed of the straightening wheel is matched with the rotational linear speed of the cigarette rubbing wheel and ensures that: when the cigarette runs to the end of the cigarette rubbing board, the working surface of the straightening claws abuts against the cigarette and ensures that the entire cigarette is in the adsorption groove. The straightening wheel also has a second angular rotation state: when the cigarette runs to the end of the cigarette rubbing board, the working surface of the straightening claws rotates to a predetermined angular displacement in the middle of the adsorption groove, and the cigarette abutted by the working surface of the straightening claws is pushed out of the adsorption groove.

[0006] The inspiration for this design came from our technicians' discovery during the debugging process that if the straightening wheel is not positioned correctly, the smoke will be rejected. To ensure that the straightening wheel functions properly, the working surface of each straightening claw of the straightening wheel must be in contact with the cigarette before it can enter the adsorption tank, and only then can the equipment operate normally. This is what we often refer to as debugging precision.

[0007] By using reverse thinking, we can take advantage of the "abnormal working state" that occurs during the debugging process to remove abnormal cigarettes. This removal actually increases the stability of our drilling.

[0008] Preferably, in the above technical solution, the straightening wheel is driven independently by a servo motor. The straightening wheel is coaxially mounted on the original straightening wheel shaft through a bearing. The servo motor transmits power to the straightening wheel through a transmission pair. The servo motor is set with two tracking points, corresponding to the reset state position point and the rejection state position point, respectively.

[0009] Preferably, in the above technical solution, the straight wheel transmission system consists of an inner transmission drum, a primary transmission shaft, a graphite airflow distribution disc, a piston mechanism, and a solenoid valve; the straight wheel has a piston mechanism;

[0010] The inner drive drum is sleeved on the original drive shaft and is driven to rotate by the original drive shaft. There are two protrusions on the outer circumference of the inner drive drum, namely the first protrusion and the second protrusion. An air inlet is opened on the axial side of the inner drive drum, and compressed air enters the piston mechanism through the air inlet and air passage.

[0011] The straight drum is sleeved on the outside of the inner drive drum via a bearing; there is an inner protrusion on the inner circumference of the straight drum, and the inner protrusion is located between the two first protrusions and the second protrusion of the inner drive drum;

[0012] A piston mechanism is provided on the side of the second protrusion of the inner drive drum corresponding to the inner protrusion. The piston mechanism is connected to the side air inlet through the air inlet port. The piston rod pushes the inner protrusion so that the straight drum is kept in the reset state.

[0013] A spring mechanism is provided on the side of the first protrusion of the inner drive drum corresponding to the inner protrusion. The spring pushes the inner protrusion so that the straight drum maintains the rejection state.

[0014] The graphite airflow distribution disc is sleeved on the original drive shaft and fixed to the frame. A circumferential groove is provided on the inner side of the disc, and the groove corresponds to the air inlet on the side of the inner drive drum shaft. The opening on the outer side of the circumferential groove of the graphite disc is connected to the output airflow of the solenoid valve.

[0015] When the solenoid valve outputs high-pressure airflow, it enters the air inlet of the rotating inner transmission drum through the groove of the graphite disc, thereby causing the piston mechanism to move. The piston rod pushes the inner protrusion, keeping the straightening drum in the reset state. At this time, the straightening wheel does not produce a rejection action, and the equipment operates normally.

[0016] When the solenoid valve stops outputting high-pressure airflow, the piston rod of the piston mechanism contracts, and the spring mechanism pushes the inner protrusion, keeping the straight drum in a rejecting state and preventing the cigarette from entering the cigarette slot of the cigarette-rubbing wheel. Thus, the cigarette is rejected by the centrifugal force of the rotating cigarette-rubbing wheel.

[0017] Preferably, in the above technical solution, the straight wheel transmission system consists of an inner transmission drum, a primary transmission shaft, a sliding protrusion, a lever mechanism, a piston mechanism, or a solenoid valve; the piston mechanism or solenoid valve is mounted on the frame and coaxial with the primary transmission shaft.

[0018] The inner drive drum is sleeved on the original drive shaft and is driven to rotate by the original drive shaft. There are two protrusions on the outer circumference of the inner drive drum, namely the first protrusion and the second protrusion. The straight drum is sleeved on the outer side of the inner drive drum through a bearing.

[0019] There is an inner protrusion on the inner side of the straight drum, and the inner protrusion is located between the two first protrusions and the second protrusion of the inner transmission drum;

[0020] A sliding protrusion is provided on the side of the second protrusion of the inner drive drum corresponding to the inner protrusion. The piston mechanism or solenoid valve pushes the lever to pull out the sliding protrusion. The sliding protrusion pushes the inner protrusion of the straightening drum to move and compress the spring, so that the straightening drum maintains the rejection state.

[0021] A spring mechanism, a piston mechanism, or a solenoid valve retracts the lever on the side corresponding to the first protrusion of the inner drive drum. The compressed spring pushes the inner protrusion of the straightening drum to move, which in turn moves the sliding protrusion, so that the straightening drum returns to and maintains the reset state.

[0022] A straightening wheel with a rejection function and its matching punching machine are composed of a cigarette rolling wheel, a straightening wheel, a cigarette rolling plate, a punching wheel, a cigarette pushing roller, and a focusing device. When the cigarette and the filter are not finished rolling and connected, the straightening wheel is set to the rejection state. The straightening wheel moves forward or backward by an angle α, and the straightening claw corresponds to the groove of the cigarette rolling wheel to prevent the filter or cigarette from entering the cigarette groove. At this time, no cigarette or filter enters the punching wheel through the groove.

[0023] When the cigarette and filter are rolled and joined together to form a complete double-length filter cigarette, the straightening wheel is set to the reset state. The straightening wheel moves backward or forward by an angle α, and the straightening claw corresponds to the edge of the cigarette rolling wheel groove, which plays the role of straightening the cigarette and guiding the cigarette into the cigarette groove. At this time, the cigarette enters the punching wheel through the cigarette groove.

[0024] With the addition of cigarette rejection function, the straightening roller compensates for the lack of cigarette rejection function in some cigarette rolling roller models. It features a compact structure, convenient implementation, and low maintenance workload. In particular, when paired with online laser drilling, it can significantly reduce the downtime probability of laser drilling machines and improve the equipment's operating rate.

[0025] Preferably, in the above technical solution, the straightening wheel is composed of a straightening drum, an inner transmission drum, a primary transmission shaft, a graphite airflow distribution disc, and a solenoid valve; the primary transmission shaft is connected to an external power source, the inner transmission drum is sleeved on the primary transmission shaft and rotates with the primary transmission shaft, the inner transmission drum has two protrusions on the outer circumference, namely the first protrusion and the second protrusion, and an air inlet is opened on the axial side, through which compressed air enters the piston mechanism;

[0026] The straight drum is connected to the outside of the inner drive drum via a bearing sleeve;

[0027] There is an inner protrusion on the inner side of the straight drum, and the inner protrusion is located between the two first protrusions and the second protrusion of the inner transmission drum;

[0028] A piston mechanism is provided on the side of the second protrusion of the inner drive drum corresponding to the inner protrusion. The piston mechanism is connected to the side air inlet through the air inlet port. The piston rod pushes the inner protrusion so that the straight drum is kept in the reset state.

[0029] A spring mechanism is provided on the side of the first protrusion of the inner drive drum corresponding to the inner protrusion. The spring pushes the inner protrusion so that the straight drum maintains the rejection state.

[0030] The graphite airflow distribution disc is sleeved on the original drive shaft and fixed to the frame. A circumferential groove is provided on the inner side of the disc, and the groove corresponds to the air inlet on the side of the inner drive drum shaft. The opening on the outer side of the circumferential groove of the graphite disc is connected to the output airflow of the solenoid valve.

[0031] When the solenoid valve outputs high-pressure airflow, it enters the air inlet of the rotating inner transmission drum through the groove of the graphite disc, thereby causing the piston mechanism to move. The piston rod pushes the inner protrusion, keeping the straightening drum in the reset state. At this time, the straightening wheel does not produce a rejection action, and the equipment operates normally.

[0032] When the solenoid valve stops outputting high-pressure airflow, the piston rod of the piston mechanism contracts, and the spring mechanism pushes the inner protrusion, keeping the straight drum in a rejecting state and preventing the cigarette from entering the cigarette slot of the cigarette-rubbing wheel. Thus, the cigarette is rejected by the centrifugal force of the rotating cigarette-rubbing wheel.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The device cleverly and proactively reproduces the original "abnormal working state" of the equipment under appropriate working conditions, and can directly eliminate cigarettes in abnormal state. It should also be noted that the identification of abnormal cigarettes is not within the scope of this application. There are multiple technical solutions for identifying abnormal cigarettes in other patent applications of the applicant and its affiliates. Attached image description:

At this time, the straightening wheel does not produce a rejection action, and the equipment operates normally.
