[0002] Feeders are commonly used equipment in tobacco processing lines. However, during use, it has been found that when the feeder discharges, a lot of material accumulates between the bottom belt and the lifting belt.

A material leveling fork is rotatably disposed above the material receiving bracket. The material leveling fork and the receiving surface of the material receiving bracket are arranged at an angle, and the material leveling fork is configured to reciprocate about the rotation axis. A drive assembly, connected to the material leveling fork drive, is used to drive the material leveling fork to reciprocate around the rotation axis, so as to push the material on the receiving bracket along the receiving surface towards the lifting belt.

One end of the rocker arm is fixedly connected to the rotating shaft, and the other end of the rocker arm is hinged to the driving end of the driving member. The driving member is configured to drive its driving end to reciprocate along a straight line, so as to drive the rotating shaft and the uniform feeding fork to reciprocate around the edge through the rocker arm.

[0022] See Figs. 1-3This application provides a feeding machine leveling device for installation on the material conveying path between the horizontal belt 100 and the lifting belt 200 of the feeding machine. It includes a receiving bracket 300, which is inclined and has its first end positioned near the discharge end of the horizontal belt 100. A preset distance is established between the first end of the receiving bracket 300 and the discharge end of the horizontal belt 100 in the horizontal direction. The receiving bracket 300 is positioned above the lifting belt 200 and is used to receive material from the horizontal belt 100. A portion of the material falling from the conveyor belt 100 is conveyed to the lifting belt 200; a material leveling fork 400 is rotatably disposed above the receiving bracket 300, the material leveling fork 400 and the receiving surface of the receiving bracket 300 are arranged at an angle, and the material leveling fork 400 is configured to reciprocate about the rotation axis; a drive assembly is drivenly connected to the material leveling fork 400, and is used to drive the material leveling fork 400 to reciprocate about the rotation axis, so as to push the material on the receiving bracket 300 along the receiving surface towards the lifting belt 200.

[0023] Specifically, a material leveling fork 400 is installed above the receiving bracket 300, capable of reciprocating around its rotation axis. The material leveling fork 400 is arranged at an angle to the receiving surface, and the preset spacing achieves material diversion, reducing the instantaneous accumulation at the junction. When the drive assembly drives the material leveling fork 400 to reciprocate, the material leveling fork 400 gradually pushes the material on the receiving surface towards the lifting belt 200. The active pushing action of the material leveling fork 400 ensures that the material smoothly transitions to the lifting belt 200 at a uniform and controllable rate, preventing the material from concentrating and tumbling at the junction.

[0024] The feeding machine leveling device provided by this invention, in use, involves installing a receiving bracket 300 at an angle on the material conveying path between the horizontal belt 100 and the lifting belt 200 of the feeding machine. The first end of the receiving bracket 300 is close to the discharge end of the horizontal belt 100, and a preset horizontal distance is maintained between the receiving bracket 300 and the discharge end. The receiving bracket 300 is positioned above the lifting belt 200. When material falls from the discharge end of the horizontal belt 100, due to the preset distance, some material falls directly onto the lifting belt 200, while the other part falls onto the receiving surface of the receiving bracket 300. A leveling fork 400 is positioned above the receiving bracket 300, arranged at an angle to the receiving surface. The driving component drives the leveling fork 400 to reciprocate around its rotation axis, uniformly feeding the material on the receiving surface towards the lifting belt 200 along the receiving surface. The aforementioned preset spacing enables material diversion, significantly reducing the amount of material at the junction of the horizontal belt 100 and the lifting belt 200. The active feeding of the material equalization fork 400 transports the material on the receiving bracket 300 to the lifting belt 200, avoiding the problems of material crushing and uneven moisture caused by stacking and rolling at the junction, thereby effectively preventing material accumulation and improving material conveying efficiency.

[0025] In some embodiments, the receiving bracket 300 is made of stainless steel and has an inclination angle of 30° to 45°. A horizontal distance of 8 to 15 cm is maintained between its first end and the outermost end of the discharge roller of the horizontal belt 100. The horizontal belt 100 conveys tobacco leaves at a constant speed. When the tobacco leaves reach the discharge end, approximately 10% to 20% of the leaves fall directly from the preset distance to the bottom of the lifting belt 200, while the remaining leaves fall onto the receiving bracket 300. The drive assembly drives the leveling fork 400 to reciprocate at a frequency of 20 to 40 times per minute. Each push of the leveling fork 400 advances the tobacco leaves on the receiving bracket 300 a certain distance towards the lifting belt 200, ensuring that the tobacco leaves are evenly distributed across the lifting belt 200 and completely eliminating material accumulation at the junction.

[0026] To optimize the above technical solution, the drive assembly includes a drive component 500 and a connector 600. The connector 600 is connected to the drive end of the drive component 500. The connector 600 is rotatably arranged, and the rotation axis of the connector 600 constitutes a rotation axis. The material leveling fork 400 is fixedly connected to the connector 600.

[0027] Specifically, the drive unit 500 outputs power, which is transmitted to the connecting unit 600 through the drive end; the connecting unit 600 rotates around its rotation axis; since the material leveling fork 400 is fixedly connected to the connecting unit 600, the material leveling fork 400 rotates together with the connecting unit 600 around the rotation axis, applying the material leveling force to the material on the receiving bracket 300. This arrangement makes the transmission path simple and clear, reduces the number of power transmission links, and increases transmission efficiency.

[0028] In some embodiments, the drive component 500 is a speed-regulating motor or cylinder, and the connecting component 600 is a shaft-like part. The connecting component 600 is mounted on the frame of the feeder via a bearing housing and can rotate freely about a horizontal axis. The root of the material leveling fork 400 is fixed to the outer surface of the connecting component 600 by bolts or welding. When the drive component 500 outputs rotational or linear motion, the connecting component 600 rotates accordingly, causing the material leveling fork 400 to reciprocate around the axis of the connecting component 600, thereby achieving uniform feeding of material on the material receiving bracket 300. The operator can adjust the output speed of the drive component 500 to change the feeding frequency according to the moisture content and flow rate of the tobacco leaves.

[0029] In the first transmission scheme of the drive assembly, the connector 600 includes a rotating shaft and a rocker arm. The rotating shaft is rotatably arranged, and the axis of the rotating shaft constitutes the rotation axis. The material leveling fork 400 is fixedly connected to the rotating shaft along one side edge of itself. One end of the rocker arm is fixedly connected to the rotating shaft, and the other end of the rocker arm is hinged to the drive end of the drive member 500. The drive member 500 is configured to drive its drive end to reciprocate along a straight line, so as to drive the rotating shaft and the material leveling fork 400 to reciprocate around the edge through the rocker arm.

[0030] Specifically, based on a crank-rocker mechanism, linear motion is converted into reciprocating oscillation. The specific connection is as follows: the connecting member 600 consists of a rotating shaft and a rocker arm. The rotating shaft is rotatably arranged, and its axis forms the rotation axis of the material leveling fork 400. The material leveling fork 400 is fixedly connected to the rotating shaft along one of its edges, allowing the entire material leveling fork 400 to rotate around this edge. One end of the rocker arm is fixedly connected to the rotating shaft, forming a crank structure; the other end of the rocker arm is hinged to the drive end of the drive member 500, forming a rotating pair. The drive member 500 outputs linear reciprocating motion. The drive end pushes or pulls the distal end of the rocker arm, converting the linear motion into rotation around the axis of the rotating shaft, thereby driving the rotating shaft and the fork fixed thereon to oscillate reciprocally around the edge. When the drive end of the drive unit 500 extends, it pushes the rocker arm to rotate in one direction around the axis of the rotating shaft, and the material leveling fork 400 swings towards the lifting belt 200 to feed the material. When the drive end retracts, it pulls the rocker arm to rotate in the opposite direction, and the material leveling fork 400 resets, ready for the next feeding stroke. This cycle repeats continuously, achieving continuous material leveling, thereby effectively preventing material accumulation and improving material conveying efficiency.

[0031] Furthermore, operators can adjust the lever arm design of the rocker arm according to the material resistance, that is, adjust the material feeding torque by changing the length of the rocker arm to adapt to different material characteristics.

[0032] To optimize the above technical solution, the driving component 500 is a driving cylinder. The cylinder body of the driving cylinder is hinged to the frame of the feeder, and the end of the piston rod of the driving cylinder constitutes the driving end. The linear motion direction of the piston rod is perpendicular to the axial direction of the rotating shaft and is coplanar with the swing plane of the rocker arm.

[0033] Specifically, the linear motion direction of the piston rod is perpendicular to the axis of the rotating shaft and coplanar with the swing plane of the rocker arm. This ensures that the direction of the driving force and the force on the rocker arm are in the same plane, and the driving force is entirely converted into the tangential driving force of the rocker arm, with no lateral component, thus maximizing transmission efficiency. In use, compressed air enters the cylinder, and the piston rod performs a linear extension and retraction motion. Since the end of the piston rod is hinged to the rocker arm, it pushes or pulls the rocker arm to rotate around the rotating shaft. The rocker arm drives the rotating shaft and the material feeding fork 400 to swing to complete the material feeding. The cylinder body swings slightly around its hinge point as the rocker arm swings, adapting to the motion geometry.

[0034] In some embodiments, the cylinder body is hinged at its tail to an ear seat on the outer side of the first side plate 700 of the feeder via a pin. A U-shaped fork is machined at the end of the piston rod, which is connected to the distal hinge hole of the rocker arm via a pin. The rotating shaft is horizontally arranged, and the extension and retraction direction of the piston rod is horizontal. The swing plane of the rocker arm is in the same plane as the piston rod axis, ensuring coplanar motion. When the piston rod extends and retracts throughout its full stroke, the rocker arm swings within a range of approximately 30° to 45°, and the cylinder body swings approximately 5° around its hinge point.

[0035] To optimize the above technical solution, the material leveling fork 400 has an X-shaped structure with a cross-center area; the connector 600 is cylindrical, passes through the cross-center area and is fixedly connected to the material leveling fork 400, and the axis of the connector 600 constitutes a rotation axis, so that the material leveling fork 400 reciprocates around the rotation axis.

[0036] Specifically, the material leveling fork 400 has four symmetrically distributed material-leveling arms, with the intersections of these arms forming a central intersection area. The connecting member 600, a cylindrical structure, passes through this central intersection area and is fixedly connected to the fork within it. The axis of the cylindrical connecting member 600 constitutes the rotation axis of the fork, passing through the geometric center of the material leveling fork 400. When the connecting member 600 rotates around its axis, it drives the entire material leveling fork 400 to rotate synchronously around its central intersection area, allowing each material-leveling arm to act on the material during rotation.

[0037] In use, the drive unit 500 drives the connecting unit 600 to reciprocate around its axis, and the X-shaped material leveling fork 400 swings back and forth around its intersection center area. During one material leveling stroke, one set of oppositely arranged material leveling arms of the X-shaped material leveling fork 400 pushes the material towards the lifting belt 200. During the reset stroke, the other set of material leveling arms can assist in tidying or pre-leveling the material on the bracket. If a continuous unidirectional rotation method is used, each set of material leveling arms will cycle through the material leveling process sequentially, resulting in a higher material leveling frequency. This arrangement doubles the material leveling frequency at the same rotation speed, significantly improving material leveling efficiency. Furthermore, each material leveling arm of the X-shaped material leveling fork 400 can be designed with different shapes or angles to adapt to different material characteristics.

[0038] In the second transmission scheme of the drive assembly, the drive component 500 includes a drive motor, the output shaft of which is coaxially and fixedly connected to the end of the connecting component 600. The drive motor is used to drive the connecting component 600 to reciprocate around its axis. That is, a drive motor is selected as the power source, and its output shaft is coaxially and fixedly connected to the end of the cylindrical connecting component 600 to form a direct drive.

[0039] In use, the control system sets the feeding parameters according to the material flow rate and conveying speed, and drives the motor to run in both forward and reverse directions alternately according to the set parameters; the motor output shaft drives the cylindrical connector 600 to rotate synchronously; the connector 600 drives the X-shaped material equalizing fork 400 to swing back and forth around its intersection center area at a set angle and frequency; the feeding stroke and feeding speed of each swing are consistent, so that the material is evenly fed to the lifting belt 200, thereby improving the material conveying efficiency.

[0040] To optimize the above technical solution, the receiving bracket 300 is an arc-shaped pipe structure, including multiple arc-shaped bars spaced apart along the width direction of the receiving bracket 300, with gaps between adjacent arc-shaped bars.

[0041] Specifically, the two ends of each arc-shaped bar can be welded to the two transverse support beams of the receiving bracket 300. Each arc-shaped bar is curved, forming an arc-shaped receiving surface. The gaps between adjacent arc-shaped bars allow small materials and dust to naturally leak down during the conveying process, preventing accumulation on the receiving bracket 300. At the same time, the arc-shaped bars provide sufficient support for normal-sized materials, ensuring smooth sliding or conveying along the receiving surface. In use, materials fall from the horizontal belt 100. Normal-sized tobacco leaves or shreds fall onto the receiving surface formed by the arc-shaped bars and are supported by them; small materials and dust fall through the gaps in the arc-shaped bars onto the lifting belt 200. When the material leveling fork 400 conveys the material on the receiving surface towards the lifting belt 200, the material slides along the arc-shaped bars with low frictional resistance. The gaps also allow the receiving surface to have a certain degree of air permeability, which is beneficial for moisture retention during the conveying process. This arrangement enables automatic separation of materials and fragments, reduces material accumulation and blockage on the receiving bracket 300, and the pipe structure reduces the weight of the receiving bracket 300, making it easier to install and clean. The gap between adjacent arc-shaped bars improves air permeability, making it suitable for materials such as tobacco that need to retain moisture.

[0042] For applications where screening of crushed materials is not required and a leak-free receiving surface is necessary, gaps in the pipe structure can cause material fragments to scatter and dust to rise. Therefore, a closed receiving structure is needed to maintain material integrity and prevent leakage. To optimize this technical solution, the receiving bracket 300 is a plate-like structure with a curved receiving surface.

[0043] During operation, material falls from the horizontal belt 100, with some falling onto the arc-shaped receiving surface of the plate-shaped receiving bracket 300. The material leveling fork 400 pushes the material on the receiving surface along the arc-shaped surface towards the lifting belt 200. Because the receiving surface is a smooth arc-shaped surface, the sliding resistance of the material is small during the conveying process, ensuring that the material remains orderly arranged during conveying. At the same time, the receiving bracket 300 is a closed plate structure, which can prevent the scattering of material fragments and dust, thereby maintaining a clean production environment.

[0044] It should be noted that the receiving bracket 300 is an arc-shaped pipe structure or a plate structure, and its two sides in the width direction are respectively fixed to the first side plate 700 and the second side plate 800 to ensure the structural stability of the device.

[0045] To optimize the above technical solution, the frame includes a first side plate 700 and a second side plate 800 arranged opposite to each other, a horizontal belt 100 and a lifting belt 200 are installed between the first side plate 700 and the second side plate 800; the cylinder body of the drive cylinder is hinged to the first side plate 700, and the end of the rotating shaft away from the drive cylinder is rotatably supported on the second side plate 800.

[0046] Specifically, the horizontal belt 100 and the lifting belt 200 of the feeder are themselves installed between the relatively arranged first side plate 700 and second side plate 800. The first side plate 700 and the second side plate 800 are the main load-bearing structures of the feeder, possessing sufficient strength and rigidity. The cylinder body of the drive cylinder is hinged to the first side plate 700, providing stable support for the drive cylinder while retaining the hinge's degree of freedom. The end of the rotating shaft away from the drive cylinder is rotatably supported on the second side plate 800, so that both ends of the rotating shaft are supported by the first side plate 700 and the second side plate 800 respectively, forming a simply supported beam structure with reasonable stress distribution.

[0047] In operation, the piston rod of the drive cylinder extends and retracts, pushing the rocker arm to rotate the rotating shaft between the first side plate 700 and the second side plate 800 around its axis. The load of the rotating shaft is transmitted to the first side plate 700 and the second side plate 800 through bearings at both ends. The material leveling fork 400 is fixed to the rotating shaft and swings between the first side plate 700 and the second side plate 800 together with the rotating shaft to level the material. The two ends of the rotating shaft are supported by the first side plate 700 and the second side plate 800, with a reasonable span and sufficient rigidity, making it less prone to bending deformation during material leveling, thus ensuring the structural stability of the device.

[0048] In some embodiments, the first side plate 700 is welded with a hinge lug, and the tail end of the cylinder body of the drive cylinder is hinged to the hinge lug by a pin. A bearing mounting hole is provided on the second side plate 800, housing a seated bearing, and the distal end of the rotating shaft passes through this bearing to form a rotational support. The end of the rotating shaft near the cylinder is mounted in a bearing seat on the first side plate 700 via another bearing. The roller shafts of the horizontal belt 100 and the lifting belt 200 are also installed between the first side plate 700 and the second side plate 800 to form a unified transmission and conveying system.

[0049] To optimize the above technical solution, the material leveling fork 400 includes multiple material leveling bars arranged side by side and spaced apart along the rotation axis, and a soft curtain is connected between two adjacent material leveling bars.

[0050] Specifically, a certain gap is left between the feeding strips to reduce the overall weight of the leveling fork 400 and save materials. A flexible curtain is connected between two adjacent feeding strips, with its two edges fixed to the adjacent feeding strips. The curtain is made of a flexible material, such as rubber, silicone, or canvas. It seals the gaps between the feeding strips, forming a continuous feeding surface and preventing material from leaking through. In use, the drive assembly rotates the leveling fork 400 back and forth. The feeding strips and the curtain work together to push the material on the receiving surface towards the lifting belt 200, ensuring the continuity of the feeding surface and improving feeding efficiency. The curtain deforms flexibly upon contact with the material, forming a flexible contact that does not damage the material, making it particularly suitable for fragile materials such as tobacco.

[0051] Furthermore, the width of the soft curtain can be adapted to the gap between adjacent arc-shaped bars, and the end of the material-equalizing fork 400 has a preset area where the soft curtain is not installed, so that the end of the material-equalizing fork can be inserted into the gap between adjacent arc-shaped bars. At the same time, the soft curtain closes the gap between adjacent arc-shaped bars, so that the material on the receiving bracket 300 can be pushed out. The pushed-out material reaches the upstream of the lifting belt and continues to be conveyed.

[0052] In some embodiments, the feeding strips are stainless steel flat bars, equidistantly arranged side by side, with their ends welded together to form a uniform feeding fork 400. A silicone soft curtain is connected between adjacent feeding strips, and the soft curtain is fixed to the feeding strips on both sides by rivets. The soft curtain is slightly longer than the feeding strips, and its lower part can hang freely to a position close to the receiving surface. During feeding, the silicone soft curtain bends and deforms according to the thickness of the material, always maintaining flexible contact with the material, pushing the tobacco leaves intact to the lifting belt 200, thereby improving material conveying efficiency while reducing the breakage rate of tobacco leaves.
