[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] In the first embodiment, an anti-jamming stepped feeding device is disclosed in this embodiment. For understanding, refer to Figures 1-4 It includes a stepped conveying table 100 and a horizontal conveying table 200. The stepped conveying table 100 includes a plurality of support tables 110 arranged in a staggered manner, and each support table 110 moves up and down along the stepped conveying table 100; in at least one state, the support table 110 at the highest position is flush with the horizontal conveying table 200. As Figure 1As shown, the drag platform is a rectangular tabletop. The stepped conveyor platform is provided with a plurality of lifting channels, and a corresponding support platform 110 is provided in each lifting channel. The drag platform moves up and down along the stepped conveyor platform. It is not difficult to understand that two adjacent support platforms 110 are flush in at least one state, so that the transported material can move from the previous conveyor platform to the next conveyor platform.

[0029] During operation, the stepped conveyor platform 100 starts to be driven by a motor, so that each support platform 110 moves up and down in the lifting channel. Under the control of the electric control system, these support platforms 110 can rise or fall independently or synchronously according to the conveying needs, so as to realize the stepped material conveying. When the material is conveyed from the lower support platform 110 to the adjacent higher support platform 110, this support platform 110 will rise to the same height as the previous support platform 110 to facilitate the smooth transition of the material. After the transition is completed, this support platform 110 will rise to the next higher position to prepare to receive the material from below. At the same time, the horizontal conveyor platform 200 is responsible for receiving the material finally conveyed by the stepped conveyor platform 100. When the material is conveyed to the horizontal conveyor platform 200 via the highest support platform 110, this support platform 110 will be flush with the horizontal conveyor platform 200 to ensure that the material can smoothly transition from the stepped conveyor platform 100 to the horizontal conveyor platform 200. The horizontal conveyor platform 200 further conveys the material to the next workstation or storage area

[0030] One side of the horizontal conveyor platform 200 faces the stepped conveyor platform 100, and a baffle 210 is provided on the other side. Figure 1 In the shown structure, the horizontal conveyor platform 200 is a conveyor belt, and the conveyor belt is used to transport workpieces. In some cases, the workpieces may get stuck when being transported by the horizontal conveyor belt. When the workpiece contacts the baffle 210 during transportation, due to friction or extrusion, the workpiece may be stuck or its moving speed may be slowed down, affecting the efficiency and safety of the entire conveying system.

[0031] In this embodiment, an induction device is further provided at the junction of the baffle 210 and the conveyor belt, which can monitor the position and state of the workpiece in real time. Once it senses that the workpiece may come into contact with the baffle 210, the system will automatically adjust the speed of the conveyor belt or pause the conveyor belt, and at the same time adjust the position of the support platform 110 on the adjacent stepped conveyor platform 100 through the control system to provide enough space for the stuck workpiece to be adjusted. And, the induction device is connected to the pusher 300.

[0032] In this example, the baffle 210 is provided with a first notch 211; a push piece 220 is provided at the first notch 211. One side of the push piece 220 faces the first notch 211, and the other side is connected to a pusher 300. In this example, the pusher 300 is used to push the push piece 220 to move towards the first notch 211, and the push piece 220 moves at least to the upper area of the horizontal conveyor table 200 in one state. It can be understood that the setting of the push piece 220 enables the pusher 300 to activate the push piece 220 when the workpiece is stuck due to contact with the baffle 210, and push the stuck workpiece forward or upward. This operation is triggered by an abnormal signal of the workpiece position detected by the sensing device. The push piece 220 moves to the upper area of the horizontal conveyor table 200, effectively pushing the stuck workpiece away from the baffle 210, readjusting its position on the conveyor belt, and restoring the normal conveying process.

[0033] In addition, the first notch 211 is to reduce the occurrence of jamming. The first notch 211 provides extra space for the workpiece. Even if there is a slight offset or accumulation at the junction of the baffle 210 and the conveyor belt, the pressure can be released through the notch, reducing direct physical obstruction. When the workpiece passes through the first notch 211, the push piece 220 can adjust or guide the workpiece through a smoother operation, avoiding transmission delay or stop caused by accumulation or misalignment.

[0034] In some preferred examples, referring to Figure 1 and in combination with Figure 4 the structure shown, the pusher 300 includes:

[0035] A first pusher 310, the first pusher 310 includes a base 311 and a first top block 312. The base 311 is fixedly connected to the stepped conveyor table. A first driver is provided in the base 311. One end of the first top block 312 is arranged in the base, and the other end faces the push piece 220; wherein, the first driver is used to drive the first top block 312 to push the push piece 220, and a telescopic member 313 is also connected between the push piece 220 and the first top block 312.

[0036] The base 311 is fixed on the side of the stepped conveyor table 100, at the junction of the horizontal conveyor table 200 and the stepped conveyor table 100. This arrangement ensures that the base 311 can stably support the first pusher 310 and the first top block 312, and at the same time enables the push piece 220 to directly act on the workpiece passing through the first notch 211. In addition, the first top block 312 moves vertically or horizontally along the base 311 under the action of the first driver.

[0037] The first driver can be a hydraulic driver, an electric motor, or a pneumatic propulsion system. In this embodiment, an electric motor is preferably used because it can provide a smooth and adjustable driving force, which is suitable for precisely controlling the position and speed of the pusher 220. The electric motor has the advantages of fast response speed and high control precision, can quickly respond to the signals of the sensors, and adjust the driving force according to the requirements of the system.

[0038] The electric motor is closely integrated with the sensors and control software through an electronic control system, and can receive the data of the workpiece position and the clamping part state in real time. These data are used to calculate the required driving force and the optimal position of the pusher 220 to ensure that the workpiece can move smoothly from the baffle 210 and avoid jamming or damage.

[0039] One end of the first top block 312 is arranged inside the driving device, and the first top block 312 is connected to the base 311 through a sliding mechanism. The sliding mechanism includes a guide rail and a slider. The guide rail is fixed inside the base 311 (not shown in the figure), and the slider is connected to the first top block 312. Driven by the electric motor, the first top block 312 moves smoothly along the guide rail, thereby pushing or pulling the pusher 220 for precise position adjustment.

[0040] During operation, when the sensor detects a clamping phenomenon or an abnormal workpiece position, the electronic control system immediately issues an instruction to the electric motor to start the first driver. At this time, the electric motor drives the first top block 312 to act along the guide rail and moves smoothly in the required direction through the slider. The movement of the first top block 312 causes the connected telescopic member 313 to extend or contract accordingly, and then pushes or pulls the connected pusher 220 to move in the direction of the workpiece.

[0041] When the pusher 220 moves above the first notch 211, it can push the jammed workpiece downward or forward according to the specific jamming situation of the workpiece. Since the pusher 220 is designed to be able to cover a wide area, this enables even large or irregular workpieces unevenly distributed on the conveyor belt to be effectively adjusted in position or released from jamming. The movement of the pusher 220 is not only based on position information, but also affected by the real-time dynamics of the workpiece on the conveyor belt, ensuring that the adjustment action is both precise and timely, minimizing the interference with the production process.

[0042] In addition, during the entire operation process, the system ensures that the force and speed of the pusher 220 match the actual situation of the workpiece through real-time monitoring. If the workpiece still fails to be released from the jammed state after moving, the system will readjust the position of the pusher 220 or increase the pushing force, and try different strategies until the problem is solved. During this process, the electronic control system continuously receives the data transmitted from the sensors.

[0043] Once the workpiece successfully removes from the clamping position and relocates on the conveyor belt, the system will instruct the conveyor belt to resume its normal operating speed and continue its material transfer to the next station. This automated fault handling mechanism greatly improves production efficiency, reduces the need for manual intervention, and minimizes downtime caused by jams.

[0044] A second pusher 320, the second pusher 320 includes a rotating shaft 321 and a lever 322. The rotating shaft 321 is fixedly connected to the stepped transport table. The middle section of the lever 322 is rotatably connected to the rotating shaft 321. One end of the lever 322 extends out a second top block 323, and the second top block 323 faces the pushing piece 220. The other end of the lever 322 is connected to a second driver, and the second driver is used to drive the lever 322 to rotate along the rotating shaft 321.

[0045] The rotating shaft 321 extends out a hollow cylinder, and the middle section of the lever 322 extends out a rod body, and the rod body is inserted into the hollow cylinder. The lever 322 realizes the function of pushing the pushing piece 220 under the driving action. Through the control of the second driver, the lever 322 is driven to rotate along the rotating shaft 321. When the second driver is activated, the power it generates will cause the lever 322 to rotate around the rotating shaft 321. This rotational movement transfers the force through the mechanical transmission of the lever 322 to one end of the lever 322, that is, the position where the second top block 323 is located. The second top block 323 moves as the lever 322 rotates, thereby pushing or pulling the directly connected pushing piece 220.

[0046] Reference Figure 1 , in some preferred examples, the pushing piece 220 is an arc-shaped piece, and a protrusion 221 is provided at the lower edge of the inner curved surface of the arc-shaped piece. The protrusion 221 is used to effectively contact the bottom of the workpiece, especially when the workpiece is stuck due to friction or other factors. When the pushing piece 220 is pushed and rotated by the second driver through the lever 322, this protrusion 221 can directly act on the bottom of the workpiece, providing an upward force. This upward force helps the stuck workpiece overcome the friction or blockage at the baffle 210, enabling the workpiece to be smoothly ejected from the stuck position.

[0047] In addition, the design of the protrusion 221 takes into account minimizing damage to the workpiece and maximizing contact efficiency, and can adapt to workpieces of various sizes and shapes without causing additional wear or damage. The material selection of the protrusion 221 is also crucial. Usually, a wear-resistant and elastic material is selected, so that it can provide sufficient force when pushing the workpiece while also protecting the workpiece from excessive impact.

[0048] As Figure 4 shown, in some examples, the telescopic member 313 is a spring.

[0049] Second Embodiment, based on the foregoing embodiment, further referring to Figure 3 , in this example, the second driver includes an electromagnetic coil and a magnet metal. The electromagnetic coil is disposed around the magnet metal, and one end of the electromagnetic coil is connected to the lever 322; the electromagnetic coil is externally connected to a power supply.

[0050] The electromagnetic coil and the magnet metal of the second driver constitute a simple electromagnetic driving mechanism, which is used to control the movement of the lever 322. The electromagnetic coil is arranged around the magnet metal to form an electromagnetic field. When the power supply is energized, the electromagnetic coil is activated to generate magnetic force, and this magnetic force can push or pull the lever 322 connected thereto.

[0051] The power supply is connected to the electromagnetic coil through a control system. The control system adjusts the magnitude and direction of the current according to the signals received from the induction device and other monitoring devices, thereby controlling the movement direction and strength of the lever 322. When it is necessary to change the position of the pusher 220 or solve the jamming problem, the system will adjust the current to change the strength of the magnetic force, so that the lever 322 rotates at an appropriate speed and angle. The electromagnetic coil and the magnet metal can accelerate one end of the lever 322, and finally cause the other end to impact the pusher 220, and then realize the function of knocking out the jammed workpiece.

[0052] In some preferred examples, the distance between the second top block 323 and the pusher 220 is not less than 2 cm. It is not difficult to understand that maintaining a certain distance can increase the impulse and achieve knocking.

[0053] Third Embodiment, according to the foregoing embodiment, in this example, the first driver and the second driver are externally connected to the same controller. In this embodiment, the first driver and the second driver are externally connected to the same controller, and this controller can be directly controlled by the user to cope with different production requirements and emergencies. The user is allowed to adjust the device operation parameters according to the real-time situation and operate the corresponding pusher 300 to contact the jam according to the specific situation when jamming occurs.

[0054] The controller is usually equipped with a user interface, including a display screen and an input device (such as a keyboard or a touch screen), and the user can directly input commands or adjust settings through these interfaces.

[0055] Fourth Embodiment, based on the foregoing embodiment, further referring to Figure 3 , a falling prevention frame 400 is further provided around the pusher 300. The falling prevention frame 400 is a frame body extending from the notch of the baffle 210. A first through hole 410 is provided at the bottom of the falling prevention frame 400, and the first through hole 410 is used for passing the pusher 300.

[0056] The fifth embodiment, based on the foregoing embodiments, refers to Figure 2 As shown, the stepped loading device further includes an inclined chute 500. The inclined chute 500 is an arc-shaped chute, and the low end of the inclined chute 500 is connected to the lowest part of the stepped conveyor table 100. The arc-shaped chute can prevent the problem that the axis direction of the cylindrical material is the same as the inclination direction of the inclined plane and cannot slide down.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
