[0002] After the stainless steel plate with certain thickness is produced, it is stacked and placed, and then transported to the subsequent processing position for processing, such as surface engraving, or punching, or other processing. Because the stainless steel plate has a certain thickness, especially for the smooth surface of the stainless steel plate, the surface cannot be scratched, so it cannot be stacked from bottom to top, and it is generally placed on a feeding rack and placed on the feeding rack from bottom to top.

[0009] The material frame is provided with a plurality of material placing positions from bottom to top, and the two ends of the material placing positions are communicated with the left side and the right side of the material frame respectively.

[0010] In the above technical solution, the lower conveying belt drives the material frame placed thereon from right to left, and the upper conveying belt drives the material frame placed thereon from left to right.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: See Figures 1-5 As shown, a stainless steel plate feeding device includes:

[0031] Rack 1;

[0032] A feeding mechanism is mounted on the frame 1. The feeding mechanism includes an upper conveyor belt 2 and a lower conveyor belt 3. The upper conveyor belt 2 is positioned directly above the lower conveyor belt 3.

[0033] The receiving mechanism is mounted on the frame 1 and is located on the left side of the feeding mechanism. The receiving mechanism includes a receiving conveyor belt 4 and a vertical drive mechanism for driving the receiving conveyor belt 4 to move vertically.

[0034] Feeding cylinder 5 is mounted on the frame 1 and fixedly installed between the upper conveyor belt 2 and the lower conveyor belt 3. The feeding cylinder 5 is located near the bottom of the upper conveyor belt 2. A push rod 6 is provided on the output shaft at the left end of the feeding cylinder 5. When the output shaft of the feeding cylinder 5 is retracted, the left end of the push rod 6 is retracted below the upper conveyor belt 2. When the output shaft of the feeding cylinder 5 is extended, the left end plane of the push rod 6 is located to the left of the left end plane of the receiving conveyor belt 4.

[0035] The material frame 7 has multiple material feeding positions 8 from bottom to top. The two ends of each material feeding position 8 are connected to the left and right sides of the material frame 7, respectively. The upper conveyor belt 2, the lower conveyor belt 3, and the receiving conveyor belt 4 are used for conveying the material frame 7.

[0036] In this embodiment, stainless steel plates are placed in the feeding positions of the material frame, with one stainless steel plate in each feeding position. Multiple feeding positions are arranged sequentially from bottom to top. In actual use, the material frame containing the stainless steel plate is placed on the right side of the lower conveyor belt and transported to the left by the lower conveyor belt. Initially, the top surface of the receiving conveyor belt is flush with the top surface of the lower conveyor belt. Then, the lower conveyor belt transports the material frame to the left, so that one material frame is transported onto the receiving conveyor belt (at this time, the top surface of the receiving conveyor belt moves to the left). Then, the vertical drive mechanism drives the receiving conveyor belt containing the material frame to move upward, so that one feeding position is directly opposite the push rod. Then, the output shaft of the feeding cylinder (the drive cylinder is a hydraulic cylinder, pneumatic cylinder, or electric cylinder) extends, causing the push rod to push the stainless steel plate to move to the left, leaving the feeding position and entering the processing equipment on the left (or its...). The feeding cylinder retracts its output shaft, disengaging it from the feeding position. The vertical drive mechanism then moves the receiving conveyor belt, which carries the material frame, upwards until a stainless steel plate is directly opposite the push rod. The feeding cylinder's output shaft extends, pushing the stainless steel plate away from the feeding position. This cycle continues until all products on the material frame are removed. The vertical drive mechanism then drives the receiving conveyor belt upwards until its top surface is flush with the top surface of the upper conveyor belt. The top surface of the receiving conveyor belt then moves to the right, conveying empty material frames to the upper conveyor belt, which then carries them away. The receiving conveyor belt then moves downwards until its top surface is parallel to the top surface of the lower conveyor belt, waiting for the lower conveyor belt to deliver the material frames containing stainless steel plates. This cycle repeats, achieving automatic feeding.

[0037] The lower conveyor belt transports the material frames placed on it from right to left, while the upper conveyor belt transports the material frames placed on it from left to right.

[0038] In this embodiment, when a material frame on the lower conveyor belt needs to be delivered to the receiving conveyor belt, the top surface of the receiving conveyor belt moves from right to left until the material frame moves onto it. Then, the receiving conveyor belt pauses, keeping the material frame stationary on the receiving conveyor belt. When it is necessary to deliver the material frame to the upper conveyor belt, the top surface of the receiving conveyor belt moves from left to right, delivering the material frame onto the upper conveyor belt.

[0039] See Figure 5 As shown, a support member 9 is provided on the front side and the rear side of the material frame 7. The rear side wall of the front support member 9 is provided with multiple front support grooves 10, and the front side wall of the rear support member 9 is provided with multiple rear support grooves 11. The front support grooves and rear support grooves are arranged at intervals from bottom to top. Each front support groove is directly opposite the rear support groove. One front support groove and one directly opposite rear support groove constitute a material feeding position.

[0040] In this embodiment, the height of the material feeding position is greater than the thickness of the product. Therefore, the bottom front and rear sides of the product are in contact with the material feeding position and will not scratch the product. More preferably, rubber and cloth protective layers are provided on the inner walls of the front support groove and the rear support groove to prevent them from scratching the stainless steel plate.

[0041] In this embodiment, the front support member includes two front support columns spaced apart from each other. Each front support column has multiple front notches on its rear sidewall, spaced apart from bottom to top. The front notches on the two front support columns correspond one-to-one, and each corresponding front notch on the two front support columns forms a front support groove. The rear support member includes two rear support columns spaced apart from each other. Each rear support column is located behind one of the front support columns. Each rear support column has multiple rear notches on its front sidewall, spaced apart from bottom to top. The rear notches on the two rear support columns correspond one-to-one, and each corresponding rear notch on the two rear support columns forms a rear support groove. Each front notch on each front support column is directly opposite each rear notch on the rear support column directly behind it.

[0042] In this structure, less material is needed for the support components; it is equivalent to using four support columns to support the four corners of the stainless steel plate, which requires less material and is more cost-effective.

[0043] A limiting plate 12 is provided on the right side of the support member 9. The limiting plate is located on the right side of the corresponding front support groove and rear support groove. This can prevent the stainless steel plate from moving to the right and leaving the feeding position, so that the stainless steel plate can only move to the left and leave the feeding position.

[0044] See Figure 2 , 4 As shown, the vertical drive mechanism includes a vertical guide rod 13, a vertical lead screw 14, a vertical drive component 15, and a bracket 16. The vertical guide rod 13 is arranged parallel to the vertical lead screw 14. The top and bottom of the vertical guide rod 13 are fixedly connected to the frame 1, respectively. The two ends of the vertical lead screw 14 are rotatably connected to the frame 1. The vertical drive component 15 drives the vertical lead screw 14 to rotate.

[0045] The rear end of the bracket 16 is slidably mounted on the vertical guide rod 13. The vertical screw 14 is connected to the bracket 16. When the vertical screw 14 rotates, it drives the bracket 16 to move vertically along the vertical guide rod 13. The receiving conveyor belt 4 is mounted on the bracket 16. The receiving conveyor belt 4 is mounted on the bracket 16 via a bracket 17.

[0046] In this embodiment, the rear end of the bracket moves vertically along the vertical guide rod. The vertical drive component is a vertical motor, which drives the vertical screw to rotate. Since the vertical screw and the support plate are screwed together, when the vertical screw rotates in one direction, it drives the support plate to move upward along the vertical guide rod, thereby causing the receiving conveyor belt and the material frame above it to move upward, so that each stainless steel plate is positioned directly opposite the push rod, which can push the product out of the material frame. When the vertical screw rotates in another direction, it drives the support plate to move downward along the vertical guide rod, thereby causing the receiving conveyor belt to move downward, realizing the up-and-down movement of the receiving conveyor belt.

[0047] See Figure 4 As shown, the front and rear sides of the left end of the bracket 16 are respectively provided with limiting cylinders 18, and a limiting member 19 is provided on the output shaft of the inner end of each limiting cylinder 18; when the output shaft of the limiting cylinder is extended, the limiting member moves directly above the receiving conveyor belt; when the output shaft of the limiting cylinder is retracted, the inner end of the limiting member moves to the outside of the receiving conveyor belt.

[0048] The material frame 7 has a positioning port 20 on the front and rear sides of the left end. When the output shaft of the limiting cylinder extends, the limiting member is inserted into the corresponding positioning port; when the output shaft of the limiting cylinder retracts, the limiting member is disengaged from the positioning port.

[0049] In this embodiment, when the lower conveyor belt transports the frame loaded with stainless steel plates to the left, the top surface of the receiving conveyor belt also transports to the left, causing the frame entering the receiving conveyor belt to also be transported to the left. During this process, after it moves to the predetermined position, the receiving conveyor belt no longer continues to transport the frame to the left. Instead, it needs to move the frame upward so that the push rod can push the stainless steel plate to the left and detach it from the frame. During the upward movement of the receiving conveyor belt and the push rod pushing the stainless steel plate to the left to detach it from the frame, in order to prevent the frame from falling off the receiving conveyor belt and to ensure safety and stability during the operation, a limiting component and a positioning port are also provided. After the frame is completely on the receiving conveyor belt, the limiting component is aligned with the positioning port. Then, the output shaft of the limiting cylinder extends, driving the limiting component to insert into the positioning port, thereby limiting the frame through the limiting component and the positioning port. In this way, when the receiving conveyor belt moves the material frame upwards and the push rod pushes the stainless steel plate to the left to detach from the material frame, the material frame can remain stably on the receiving conveyor belt, ensuring stability and safety during the feeding process. More preferably, front and rear side plates are respectively installed on the front and rear sides of the support to prevent the material frame from moving back and forth and detaching from the receiving conveyor belt.

[0050] See Figure 4As shown, the limiting component is a conical structure with a smaller inner diameter and a larger outer diameter. Due to its conical structure, even if the positioning opening is not completely aligned with the limiting component, and the material frame has a slight offset, when the output shaft of the limiting cylinder extends, the inner end of the limiting component will insert into the positioning opening. As the limiting component continues to move inward, part of its outer surface will contact the inner wall of the positioning opening. At this point, the limiting component continues to move inward, pressing against the positioning opening through the conical structure and causing the material frame to move synchronously a certain distance until the limiting component is fully inserted into the positioning opening. When the output shaft of the limiting cylinder is fully extended, the limiting component is inside the positioning opening, with the outer edge of the limiting component near its outer end face inside the opening and the outer end of the limiting component outside. Therefore, when it is necessary to release the limiting component from the material frame, the output shaft of the limiting cylinder retracts and moves the limiting component outward without being jammed by the positioning opening, ensuring that the limiting component disengages from the material frame. After all the stainless steel plates in the material frame are pushed away from the material frame, when the top surface of the receiving conveyor belt is flush with the top surface of the upper conveyor belt, the output shaft of the limit cylinder retracts, causing the limit component to disengage from the limit port. At this time, the top surface of the receiving conveyor belt moves to the right, causing the empty material frame to move to the right, disengage from the receiving conveyor belt, and move to the upper conveyor belt.

[0051] The frame 1 is also equipped with a photoelectric sensor, which is positioned above the left end of the lower conveyor belt 2.

[0052] Multiple material frames are placed on the lower conveyor belt at the same time, while the receiving conveyor belt can only place one material frame at a time. Therefore, the lower conveyor belt transports intermittently. After a material frame is delivered to the receiving conveyor belt, when another material frame on the right moves to the left end of the lower conveyor belt, the photoelectric sensor will detect the material frame. At this time, the lower conveyor belt will temporarily stop working, and the material frame will not be transported to the left. After the receiving conveyor belt is empty, it will transport another material frame to the left onto the receiving conveyor belt, and so on.

[0053] See Figures 1-3 As shown, a baffle 21 is provided at the right end of the upper conveyor belt 2.

[0054] In this embodiment, a robotic arm can be installed above the upper conveyor belt, and a baffle can be used to prevent the material frames from being conveyed to the right. The robotic arm can then grab the empty material frames, thus eliminating the need for an excessively long upper conveyor belt and reducing space usage.

[0055] In this utility model, the upper conveyor belt, the lower conveyor belt, and the receiving conveyor belt are all equipped with corresponding motor drives and transmissions.
