[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides an automatic feeder for cutting waste, comprising: The conveying assembly 100 includes a bracket 101, a main frame 102 fixedly connected to one side of the end of the bracket 101, a main conveyor belt 103 adapted to be installed in the middle of the main frame 102, a material tray 104 slidably installed on the side wall of the main conveyor belt 103, a secondary frame 105 fixedly connected to the other side of the end of the bracket 101, and a secondary conveyor belt 106 adapted to be installed in the middle of the secondary frame 105. The secondary conveyor belt 106 is arranged parallel to the main conveyor belt 103. A groove for cooperating with the material tray 104 is provided between the main frame 102 and the secondary frame 105. The switching component 200 includes a connecting platform 201 fixedly connected to the end of the main frame 102, a connecting seat 202 fixedly connected to the side wall of the bracket 101, a sliding member 203 slidably installed on the side wall of the connecting seat 202, and a material-pushing plate 204 fixedly connected to the end of the sliding member 203. The end of the connecting platform 201 is connected to the end of the sub-frame 105. The upper surface of the connecting platform 201 is flush with the upper surfaces of the sub-conveyor belt 106 and the main conveyor belt 103, respectively. The end of the material-pushing plate 204 slides in contact with the inner side of the connecting platform 201, and a groove is provided in the middle of the connecting platform 201 to cooperate with the material tray 104.

[0019] The main frame 102 is bolted to one side of the support 101, serving as the mounting carrier for the main conveyor belt 103. The main conveyor belt 103 (using a chain conveyor or belt conveyor structure, capable of bearing the cutting waste) is installed inside the main frame 102. The material tray 104 is slidably mounted on the side wall of the main conveyor belt 103 to directly bear the cutting waste (the tray has a retaining edge to prevent the waste from slipping). A groove is provided on the inner side of the main frame 102 to cooperate with the bottom slider of the material tray 104. The groove guides the material tray 104 and limits its lateral displacement, ensuring conveying stability. The power source of the main conveyor belt 103 (such as a geared motor, not shown in the figure) is driven by a chain or belt, moving the material tray 104 along the length of the main frame 102 to transport the waste from the processing area to the switching area. The secondary frame 105 is fixedly connected to the other side of the support 101 and is arranged parallel to the main frame 102. The intermediate frame 105 has reserved installation space for the switching component 200; the intermediate frame 105 is fitted with an intermediate conveyor belt 106, whose conveying direction is opposite to that of the main conveyor belt 103 (the main conveyor belt conveys the remaining material to the switching area in the forward direction, and the intermediate conveyor belt sends the empty material tray or the remaining material to be reused back in the reverse direction); the inner side of the intermediate frame 105 is also provided with a sliding groove that cooperates with the material tray 104, and the upper end face of the intermediate conveyor belt 106 is at the same height as the upper end face of the main conveyor belt 103, ensuring that there is no height difference obstruction when the material tray 104 switches between the two; the upper end face of the connecting platform 201 is at the same height as the upper end face of the main conveyor belt 103 and the intermediate conveyor belt 106, and a sliding groove is provided in the middle that cooperates with the bottom slider of the material tray 104. The sliding groove is aligned with the sliding grooves of the main and intermediate frames, ensuring that the material tray 104 moves in a straight line during the switching process and avoids jamming; the inner side of the connecting platform 201 is a smooth working surface that slides in contact with the end of the material feeding plate 204 to reduce frictional resistance during switching. The connecting seat 202 is fixed to the side wall of the bracket 101 by bolts and is located above the connecting platform 201. A guide rail is provided on its side wall. The sliding member 203 is slidably installed on the guide rail and can move back and forth along the length direction of the connecting seat 202 (perpendicular to the conveying direction of the main and auxiliary conveyor belts). The material feeding plate 204 is vertically fixed to the end of the sliding member 203 and extends to the inner side of the connecting platform 201. Its plate surface is adapted to the side wall of the material tray 104 (can fit the edge of the material tray). This realizes the switching from the main conveyor belt to the auxiliary conveyor belt.

[0020] Specifically, the switching assembly 200 also includes a propulsion cylinder 205 fixedly connected to the end side wall of the connecting seat 202, and the output shaft end of the propulsion cylinder 205 is fixedly connected to the side wall of the sliding member 203.

[0021] The propulsion cylinder 205 is fixedly connected to the end side wall of the connecting seat 202, and the output shaft is coaxially fixed with the side wall of the sliding member 203. When the propulsion cylinder 205 extends or retracts, it can drive the sliding member 203 to move along the guide rail, thereby driving the material feeding plate 204 to push the material tray 104 to slide laterally on the connecting platform 201, realizing the switching from the main conveyor belt to the auxiliary conveyor belt.

[0022] Furthermore, the end sidewall of the connecting seat 202 is bolted to a limiting block 206, and a spring post 207 is threadedly connected to the middle of the limiting block 206. The spring posts 207 are symmetrically arranged on the sidewall of the sliding member 203.

[0023] When the slider 203 moves to its limit position, the spring column 207 absorbs the impact force through elastic deformation, preventing the slider from rigidly colliding with the limit block, and at the same time limiting the maximum stroke of the slider.

[0024] Furthermore, the side wall of the connecting seat 202 is bolted to a positioning plate 208, the end of which is provided with a positioning hole and extends to the top of the docking platform 201.

[0025] The positioning plate 208 is used to calibrate the switching endpoint position of the material tray 104 to ensure that the material tray accurately aligns with the chute of the auxiliary conveyor belt 106, and can also assist in detecting whether the material tray has completely entered the auxiliary conveyor area.

[0026] Preferably, the conveying assembly 100 also includes an intercepting cylinder 107 fixedly connected to the side wall of the bracket 101, and an insert 108 fixedly connected to the end of the output shaft of the intercepting cylinder 107. The side wall of the tray 104 is provided with a slot that engages with the protrusion at the end of the insert 108.

[0027] When the output shaft of the intercepting cylinder 107 extends, the protrusion of the insert block 108 is inserted into the tray slot to achieve precise positioning and temporary interception of the tray 104.

[0028] It should be noted that a sensor mounting plate 109 is bolted to the side wall of the main frame 102, and the sensor mounting plate 109 is used in conjunction with the plug block 108.

[0029] The sensor mounting plate 109 is bolted to the side wall of the main frame 102. A photoelectric sensor or a proximity switch can be installed on it and used in conjunction with the plug block 108. When the sensor detects that the material tray 104 has reached the preset position, it triggers the interception cylinder 107 to achieve automated interception and positioning.

[0030] Preferably, a baffle 110 is bolted to the side wall of the bracket 101, and the end of the baffle 110 is snapped into the end of the main frame 102.

[0031] The baffle 110 is bolted to the side wall of the bracket 101 and its end is snapped into the end of the main frame 102 to form lateral protection, preventing the material tray 104 from slipping off the edge of the main frame during conveying or switching, and at the same time playing an auxiliary guiding role for the remaining material.

[0032] During use, the leftover material generated during the cutting process is placed in the material tray 104. The main conveyor belt 103 starts and drives the material tray 104 to move along the slide groove of the main frame 102 towards the switching area through friction or chain drive. The baffle 110 restricts the lateral displacement of the material tray to ensure the stability of the conveying path. When the material tray 104 moves to the sensor mounting plate 109, the sensor detects the signal and feeds it back to the control system. The output shaft of the intercepting cylinder 107 extends and drives the protrusion of the insert block 108 to insert into the material tray slot. The material tray 104 stops moving and waits for the switching component 200 to switch the path. The material tray 104 is positioned by the intercepting cylinder 107 at the junction of the main conveyor belt 103 and the connecting platform 201. The material-pushing plate 204 is in its initial position (close to the main conveyor belt) and is in contact with the side wall of the material tray 104. The control system sends a switching signal, the output shaft of the push cylinder 205 extends, and drives the sliding member 203 to move along the guide rail of the connecting seat 202 towards the auxiliary conveyor belt. The material-pushing plate 204 simultaneously pushes the material tray 104 to slide along the groove of the connecting platform 201. When the material tray 104 is about to enter the auxiliary conveyor belt 103... At 06:00, the sliding member 203 touches the spring column 207. The spring column buffers the impact force through compression deformation, preventing the material tray from moving excessively due to inertia. At the same time, the positioning plate 208 calibrates the position of the material tray to ensure that it falls accurately into the chute of the sub-frame 105. After the material tray 104 is fully entered into the sub-conveyor belt 106, the output shaft of the push cylinder 205 retracts, driving the sliding member 203 and the material feeding plate 204 to reset to the initial position, waiting for the next switching command. The spring column 207 elastically resets, preparing for the next buffering.

[0033] After the waste material is unloaded or sorted, the empty material tray (or the waste material that needs to be reused) is transferred to the secondary conveyor belt 106 through the switching component. The secondary conveyor belt 106 starts (running in the opposite direction to the main conveyor belt), driving the material tray back to the initial position along the chute of the secondary frame 105, so as to realize the recycling of the material tray and the waste material.

[0034] In summary, the device improves waste material handling efficiency by using a main conveyor belt to transport trays containing surplus material, a switching component to achieve path conversion, and an auxiliary conveyor belt to return empty trays. This adapts to the continuous processing rhythm of production lines and reduces downtime caused by waste material accumulation. It also reduces labor costs and safety risks by replacing traditional manual handling. The chutes in the main and auxiliary frames guide and constrain the trays, and the lateral protection of the baffles prevents waste material from slipping or shifting during transport. The intercepting cylinder, through the cooperation of the insert block and the tray slot, positions the tray, ensuring precise docking between the tray and the connecting platform during switching. The equal-height design of the connecting platform and the main and auxiliary conveyor belts, along with the chute alignment structure, prevents collisions and deformations caused by height differences or path deviations, ensuring the reuse value of the waste material. Furthermore, it promotes waste material recycling and reduces material waste by enabling direct return of waste material from the processing area to the reuse area, reducing losses in intermediate transfer links and improving the waste material recovery rate.
