Description

TECHNICAL FIELD

[0001] The present application relates to a paper dunnage filling machine. BACKGROUND

[0002] The paper dunnage filling machine is a packaging equipment for processing paper into paper dunnage to fill in the packaging box, which plays a buffering and shockproof role to protect the product from being damaged during transportation.

[0003] The traditional paper dunnage filling machine relies on a pair of rubber wheels rotating in opposite directions to rub the paper in and out. After long-term use, the surface of the rubber wheel will wear out, the friction will decrease, and the paper dunnage will not be able to be stably transported, which will affect the continuous forming quality of the paper dunnage. Moreover, after the rubber wheel wears out, the paper dunnage may be difficult to feed, jam or deviate, resulting in loose paper dunnage, uneven thickness, and even machine shutdown, which will reduce the packaging efficiency of the subsequent packaging process.

[0004] The internal layout of the traditional paper dunnage filling machine is complex, and the rubber wheel group and the flow channel components are arranged in multiple layers, which results in a large overall size of the machine. When disassembling, multiple components need to be disassembled one by one, which consumes time and labor, increases labor costs, and paper dust is easily accumulated in the gap between the rubber wheels, transmission gears and other parts after long-term use. Long-term accumulation will increase the transmission resistance and noise, and even cause mechanical jamming.

[0005] The traditional paper dunnage filling machine lacks real-time detection mechanism for rubber wheel slip, and the operator can only judge whether the rubber wheel is failed by observing the abnormality of the paper dunnage forming, which will delay the discovery of the problem, affect the production efficiency, lack the early warning function, and may cause batch waste due to sudden failure of the rubber wheel.

[0006] The traditional paper dunnage filling machine does not set a sensor at the outlet of the paper dunnage or sets a single sensor, which cannot accurately detect whether the paper dunnage is normally output. The rubber wheel may idle, and the paper breakage may not be discovered in time, which will cause the packaging process to be interrupted, and frequent manual intervention will increase the operation complexity and does not conform to the automation trend.

[0007] Therefore, how to overcome the above technical defects is a technical problem to be solved by those skilled in the art. SUMMARY

[0008] The purpose of the present application is to provide a paper dunnage filling machine to solve at least one of the above technical problems.

[0009] According to one aspect of the present application, a paper dunnage filling machine is provided, comprising:

[0010] a feeding port;

[0011] a discharging port;

[0012] A flow channel, one end of the flow channel being in communication with the feed port and the other end being in communication with the discharge port; and

[0013] A paper feed assembly, the paper feed assembly comprising a driving wheel, a driven wheel, a driving component and a pressing mechanism, the driving wheel and the driven wheel both extending into the flow channel, the driving component driving the driving wheel to rotate, the pressing mechanism being capable of driving the driven wheel to press against the driving wheel, the driving wheel driving the driven wheel to rotate to drive the paper mat in the flow channel to be transported towards the discharge port.

[0014] The filling paper mat machine of the present application, the raw paper enters from the feed port, the paper is shrunk after being pressed at the feed port and becomes a paper mat which enters the flow channel, under the action of the driving component, the driving wheel and the driven wheel of the paper feed assembly bite the paper mat and transport the paper mat towards the discharge port, the driving wheel and the driven wheel can continuously transport the formed paper mat towards the discharge port, the filling paper mat machine itself has a cutter structure, the cutter mechanism of the filling paper mat machine cuts the transported paper mat into a set length, since the pressing mechanism can drive the driven wheel to press against the driving wheel, the driven wheel is tightly attached to the driving wheel, a stable pressing force is generated, the pressing force between the driving wheel and the driven wheel can make the forming of the paper mat more firm and not easy to loosen, the continuous forming quality of the paper mat is ensured, and the problem of paper mat slipping and jamming can be solved, the pressing mechanism can also realize self-compensation of the wheel surface wear of the driving wheel and the driven wheel after long time running, and a gap between the driving wheel and the driven wheel is not generated to cause paper feed slipping.

[0015] In some embodiments, the pressing mechanism can comprise a swing frame and a tension spring, the driven wheel is hinged to the swing frame, one end of the tension spring is arranged on the swing frame, the other end of the tension spring is fixed, the tension spring can drive the swing frame to swing to press the driven wheel against the driving wheel.

[0016] Therefore, the spring can tighten the swing frame, the driven wheel on the swing frame is tightly attached to the driving wheel, a stable pressing force is generated, the swing frame can swing slightly during paper feed, the paper mat with random thickness change after forming can pass between the driving wheel and the driven wheel without slipping or jamming, the use of the spring to tighten the driven wheel can realize self-compensation of the wheel surface wear of the driving wheel and the driven wheel after long time running, a gap between the driving wheel and the driven wheel is not generated to cause paper feed slipping, the design of the spring tightening the driven wheel and the slight swing of the driven wheel can solve the problem of paper mat slipping and jamming, and realize self-compensation of the wheel surface wear of the driving wheel and the driven wheel at the same time.

[0017] In some embodiments, the base can also be included, the swing frame includes a mounting column, an upper mounting plate, a lower mounting plate and a rotating shaft, the end of the mounting column is arranged on the base, one end of the upper mounting plate and one end of the lower mounting plate are arranged on the mounting column and can rotate on the mounting column, the driven wheel is sleeved on the rotating shaft, and the two ends of the rotating shaft are respectively hinged on the upper mounting plate and the lower mounting plate, and one end of the tension spring is arranged on the upper mounting plate.

[0018] Therefore, under the tension of the tension spring, the upper mounting plate, the lower mounting plate and the driven wheel can swing as a whole with the mounting column as the swing center, so that the driven wheel between the upper mounting plate and the lower mounting plate is closely attached to the driving wheel to generate stable pressing force, the driven wheel can swing slightly when the paper passes, so that the paper mat with random thickness change after molding will not slip or jam when passing between the driving wheel and the driven wheel, and when the paper passes between the driving wheel and the driven wheel, the driving wheel can drive the driven wheel to rotate on the swing frame in the direction opposite to the rotation direction of the driving wheel through the friction of the paper mat, so as to continuously convey the molded paper mat to the discharge port.

[0019] In some embodiments, a detection device, a controller and an alarm can also be included, the detection device is used to detect whether the rotation of the driven wheel is normal, the detection device is electrically connected with the controller, and the controller is electrically connected with the alarm.

[0020] Therefore, when the paper jam occurs in the flow channel, the rotation of the driven wheel will be abnormal, such as the driven wheel stops rotating or rotates at a very slow speed, at this time, the detection device detects that the rotation of the driven wheel is abnormal, and the detection device sends the detected signal to the controller, and the controller controls the alarm to alarm to inform the operator to handle the paper jam in the first time, so that the paper mat is not molded badly, and the production efficiency of the filling paper mat machine is not affected, and batch waste caused by sudden failure of the driven wheel (the driven wheel stops rotating or rotates at a very slow speed) is avoided.

[0021] In some embodiments, the detection device can be a proximity switch, a plurality of detection columns are arranged on the end face of the driven wheel along the circumference of the driven wheel,

[0022] When the driven wheel rotates normally, the detection column can trigger the proximity switch at a time interval T,

[0023] When the paper jam occurs in the flow channel, the detection column always triggers the proximity switch, cannot trigger the proximity switch or triggers the proximity switch at a time interval greater than T.

[0024] Thus, when the paper is fed normally, the plurality of detection columns on the end surface of the driven wheel stably trigger the proximity switch at a time interval T, i.e. the proximity switch sends a switch signal to the controller at a stable time interval T, and the controller determines that the driven wheel rotates normally. When a paper jam occurs in the flow channel, the rotation of the driven wheel is abnormal, and the driven wheel either stops rotating or rotates very slowly. At this time, the driving wheel is always rotating, and the paper pad is not fed or is fed very slowly. At this time, the driven wheel is in a slipping state. When the driven wheel stops rotating, the detection columns on the end surface of the driven wheel either always trigger the proximity switch or cannot trigger the proximity switch, i.e. the proximity switch either always generates a switch signal or cannot generate a switch signal. The proximity switch cannot send a switch signal to the controller at a stable time interval T, and the controller determines that the driven wheel rotates abnormally. The controller controls the alarm to alarm to notify the operator to handle the paper jam in the first time. When the driven wheel rotates very slowly, the detection columns on the end surface of the driven wheel trigger the proximity switch at a time interval greater than T, and the proximity switch sends a switch signal to the controller at a time interval greater than T. The controller determines that the driven wheel rotates abnormally, and the controller controls the alarm to alarm to notify the operator to handle the paper jam in the first time.

[0025] In some embodiments, the driving component can be a motor, and the driving component is inserted into the driving wheel.

[0026] Thus, since the driving component is inserted into the driving wheel, the wheel surface of the driving wheel for feeding paper can be close to the middle of the motor, instead of being directly mounted on the motor shaft like the traditional cylindrical wheel body. This can reduce the height of the driving component and the overall height of the driving wheel, thereby reducing the height of the entire machine, optimizing the internal structural layout of the paper filling machine to reduce the volume of the entire machine, and reducing the weight of the entire machine. This greatly improves convenience and flexibility, and can meet various use scenarios.

[0027] In some embodiments, a connecting shaft sleeve can also be included, the end surface of the driving wheel is provided with an annular protrusion, the inner wall of the annular protrusion is provided with a first flat portion, the outer wall of the connecting shaft sleeve is provided with a second flat portion, the connecting shaft sleeve is sleeved on the driving shaft of the driving component and rotates synchronously with the driving shaft of the driving component, and the connecting shaft sleeve is inserted into the annular protrusion after passing through the driving wheel and the second flat portion abuts against the first flat portion.

[0028] Thus, the driving shaft of the driving component can drive the connecting sleeve to rotate synchronously, the connecting sleeve can drive the driving wheel to rotate through the annular protrusion, the cooperation between the second flat part and the first flat part can ensure the synchronous rotation of the driving wheel and the connecting sleeve, the driving component can drive the driving wheel to rotate synchronously through the connecting sleeve, the driving component is inserted into the driving wheel, the wheel surface of the driving wheel for paper feeding is close to the middle part of the motor, so that the height of the driving component and the driving wheel as a whole can be reduced, the transmission structure between the traditional motor and the driving wheel is omitted, the space inside the machine is saved, the internal structure layout of the paper pad filling machine can be optimized to reduce the overall size of the machine.

[0029] In some embodiments, a base and a bearing seat can be further included, the end of the connecting sleeve is fixed in the inner ring of the bearing seat, and the bearing seat is arranged on the base.

[0030] Thus, the connecting sleeve can rotate smoothly on the bearing seat, ensuring that the driving wheel can rotate smoothly, so that the paper pad can be smoothly fed to the direction of the discharge port, and the motor can be installed inside the paper pad filling machine through a fixed seat to ensure the stability of the driving component and the driving wheel as a whole.

[0031] In some embodiments, a first detection sensor and / or a second detection sensor can be further included, a reversible protection door is arranged at the discharge port, the first detection sensor can detect whether the protection door is turned open, and the second detection sensor can detect whether the paper pad is sent out from the discharge port.

[0032] When the paper mat is sent out from the discharge port, the reversible protection door is lifted by the paper mat, the first detection sensor detects that the protection door is opened, at this time, the paper mat filling machine is in a normal discharging state, when the cutting mechanism of the paper mat filling machine cuts off the paper mat, the paper mat is taken away for use, the protection door falls down, the first detection sensor detects that the protection door is closed, at this time, the paper mat filling machine is automatically stopped to avoid the situation that the driving wheel is idling or the paper breakage is not discovered in time; or when the paper mat is sent out from the discharge port, the reversible protection door is lifted by the paper mat, the second detection sensor detects that the paper mat is out, at this time, the paper mat filling machine is in a normal discharging state, when the cutting mechanism of the paper mat filling machine cuts off the paper mat, the paper mat is taken away for use, the protection door falls down, the second detection sensor detects that the discharge port is empty, at this time, the paper mat filling machine is automatically stopped to avoid the situation that the driving wheel is idling or the paper breakage is not discovered in time; or when the paper mat is sent out from the discharge port, the reversible protection door is lifted by the paper mat, the first detection sensor detects that the protection door is opened, and the second detection sensor detects that the paper mat is out, at this time, the paper mat filling machine is in a normal discharging state, when the cutting mechanism of the paper mat filling machine cuts off the paper mat, the paper mat is taken away for use, the protection door falls down, the first detection sensor detects that the protection door is closed, and the second detection sensor detects that the discharge port is empty, at this time, the paper mat filling machine is automatically stopped to avoid the situation that the driving wheel is idling or the paper breakage is not discovered in time, the first detection sensor and the second detection sensor can jointly monitor the output state of the paper mat in real time to ensure the accuracy of monitoring, automatically stop when the driving wheel is idling or the paper breakage occurs, reduce manual intervention, and reduce the operation complexity.

[0033] In some embodiments, the protection door can include a door body and a flip shaft, two ends of the flip shaft are respectively inserted into two opposite side walls of the discharge port, the flip shaft can rotate on the side walls of the discharge port, the top of the door body is arranged on the flip shaft, and a detection sheet is arranged on the end of the flip shaft.

[0034] The first detection sensor can be a proximity switch, and the first detection sensor is arranged on the side of the detection sheet.

[0035] When the door body is closed, the detection sheet can trigger the proximity switch.

[0036] The second detection sensor can be a reflection type photoelectric sensor, and the emission part and the receiving part of the reflection type photoelectric sensor are arranged on two opposite side walls of the discharge port.

[0037] When the paper mat is sent out from the discharge port, the paper mat can trigger the reflection type photoelectric sensor.

[0038] Thus, when the paper pad is sent out from the discharge port, the door body is lifted by the paper pad, the door body drives the turnover shaft to rotate, the turnover shaft drives the detection sheet to move away from the proximity switch, the proximity switch does not generate a switch signal, the photoelectric sensor detects that there is a paper pad, at this time, the filling paper pad machine is in a normal discharge state, when the cutting knife mechanism of the filling paper pad machine cuts off the paper pad, the paper pad is taken away for use, the door body falls down, the door body drives the turnover shaft to rotate, the turnover shaft drives the detection sheet to move close to the proximity switch, the detection sheet triggers the proximity switch, the proximity switch generates a switch signal, the photoelectric sensor detects that there is no paper pad in the discharge port, at this time, the filling paper pad machine automatically stops to avoid the situation that the driving wheel is idling or the paper is not discovered in time, the proximity switch and the photoelectric sensor can monitor the output state of the paper pad in real time, and the driving wheel is automatically stopped when idling or the paper is broken.
