[0027] As shown in Figure 1 , Figure 3 , Figure 7As shown, in some embodiments of the present application, the opening and closing mechanism comprises a first worm 51 rotatably mounted on the material frame, a first worm wheel 50 engaged with the first worm 51, the first worm 51 and the first worm wheel 50 being arranged in a first sealing box 49, one end of the first worm 51 being provided with a first clutch 33, the second feeding device 27 being provided with a second clutch 41 matched therewith, the second clutch 41 being connected with the output shaft of the first rotary driver 40, the second clutch 41 being able to drive the first worm 51 to rotate when the second clutch 41 is engaged with the first clutch 33, a first limiting piece 29 being mounted on the rotating shaft of the first worm wheel 50, the first limiting piece 29 being able to limit the entry and exit of the material frame when the first limiting piece 29 rotates to the range of the inlet and outlet.

[0028] Now looking at Figure 1 When the lifting frame 28 is positioned above the second feeding device 27, the first sealing box 49 is mounted on the bottom crossbar of the lifting frame 28, and the length direction of the first sealing box 49 is consistent with the width direction of the second feeding device 27, the two ends of the first worm 51 can be rotatably connected with the side wall of the first sealing box 49 through sealing bearings, the first worm 51 is arranged along the length direction of the first sealing box 49 and is in meshing transmission with the first worm wheel 50, the rotating shaft of the first worm wheel 50 extends to the outside through the side of the first sealing box 49 and is fixedly provided with the first limiting piece 29 at one end thereof, the first limiting piece 29 can rotate with the rotating shaft, one end of the first worm 51 extends out of the first sealing box 49 and is fixedly connected with the first clutch 33, and the second clutch 41 is mounted on the side of the second feeding device 27 close to the first clutch 33 and is fixedly connected with the output shaft of the first rotary driver 40, when the lifting frame 28 is positioned above the second feeding device 27, the first clutch 33 and the second clutch 41 are in relative positions, at this time, the second clutch 41 is engaged with the first clutch 33 through the control system, thereby driving the first worm 51 to rotate, the first limiting piece 29 is rotated to a set angle through the transmission of the first worm wheel 50, thereby opening the inlet and outlet of the lifting frame 28 and allowing the material frame to smoothly enter the inside of the lifting frame 28, after the material frame enters the inside of the lifting frame 28, the control system will issue instructions again, the first rotary driver 40 is reversely operated to reversely rotate the first worm 51, and the first worm wheel 50 is reversely rotated synchronously to drive the first limiting piece 29 to return to the initial position, thereby closing the inlet and outlet of the lifting frame 28.

[0029] Further, the first clutch 33 and the second clutch 41 are friction disc clutches, which transmit power through the friction between the friction plates, and have the advantages of simple structure and smooth engagement. When the second clutch 41 is engaged with the first clutch 33, power is transmitted from the first rotary driver 40 to the first worm 51 through the second clutch 41 and the first clutch 33, so that the transmission system can run continuously. In order to ensure the stability and reliability of the transmission process, the first sealing box 49 is designed to be waterproof and dustproof, so as to effectively protect the internal transmission components from the influence of the external environment.

[0030] As shown in Figure 3 , in some specific embodiments of the present application, a relief opening 32 is formed in the side wall of the lifting frame 28 for the engagement of the first clutch 33 and the second clutch 41. Further, in order to facilitate the accurate positioning of the first clutch 33 and the second clutch 41 during engagement, a horn-shaped guide mechanism can be provided at the relief opening 32.

[0031] As shown in Figure 3-4 , in some embodiments of the present application, a second limiting part 30 is installed on one side of the lifting frame 28 relative to the first worm 51 and the first worm gear 50, and a spacing is left between the second limiting part 30 and the lifting frame 28 for the first limiting part 29 to extend into. When the first limiting part 29 rotates to the set angle with the rotating shaft, the end thereof extends into the spacing between the second limiting part 30 and the lifting frame 28, forming a limiting fit, which improves the reliability of the material frame loading and unloading process.

[0032] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 7 , in some embodiments of the present application, a second worm and a second worm gear are rotatably installed on the lifting frame 28 and mesh with each other, the second worm and the second worm gear are arranged in the second sealing box 35, the second worm is arranged in parallel with the first worm 51, one end of the second worm is provided with a third clutch 34, the second feeding device 27 is provided with a fourth clutch 39 matched therewith, the fourth clutch 39 is connected with the output shaft of the second rotary driver 38, the fourth clutch 39 can drive the second worm to rotate when the fourth clutch 39 is engaged with the third clutch 34, a cam 36 is installed on the rotating shaft of the second worm gear, the second limiting part 30 is vertically slidably connected with the lifting frame 28, and the second limiting part 30 and the lifting frame 28 have a vertical limiting groove 25 therebetween.

[0033] When the first limiting piece 29 rotates to the vertical direction, the second rotary driver 38 starts and makes the fourth clutch 39 engage with the third clutch 34, drives the second worm to rotate, and drives the cam 36 to rotate through the second worm transmission, the cam 36 drives the second limiting piece 30 to slide along the vertical direction, and the one end of the first limiting piece 29 away from the rotating shaft is inserted into the vertical limiting slot 25, so as to limit the rotating direction of the first limiting piece 29.

[0034] Specifically, as shown in Figure 3 , the hoisting frame 28 is provided with a vertical sliding groove 31 at the top, the second limiting piece 30 passes through the sliding groove 31 and is in sliding connection with the sliding groove 31, and the sliding groove 31 is provided to ensure the stable movement of the second limiting piece 30 in the vertical direction and limit the transverse displacement of the second limiting piece 30. As shown in Figure 4 , the second limiting piece 30 has a supporting surface below the cam 36, and the elastic telescopic rod 37 is installed between the supporting surface and the hoisting frame 28, the elastic telescopic rod 37 applies an upward force to the second limiting piece 30, so that the second limiting piece 30 always keeps in contact with the cam 36, when the cam 36 rotates to the lowest point, the second limiting piece 30 moves to the lowest point, at this time, the end of the first limiting piece 29 is located in the vertical limiting slot 25 of the second limiting piece 30, the second limiting piece 30 can limit the side of the first limiting piece 29 away from the hoisting frame 28, and the sidewall of the vertical limiting slot 25 in the width direction of the hoisting frame 28 can limit the rotating direction of the first limiting piece 29, so as to further avoid the rotation of the first limiting piece 29.

[0035] As shown in Figure 1 , Figure 2 , and Figure 5 , in some embodiments of the present application, the second feeding device 27 is provided with a bracket 17 on one side, the first linear driver 48 is installed on the second feeding device 27 along the sliding direction of the bracket 17, the output shaft of the first linear driver 48 is connected with the bracket 17, and the first rotary driver 40 and the second rotary driver 38 are installed on the bracket 17.

[0036] Specifically, the guide rail 46 is installed on the second feeding device 27 in the width direction, the guide rail 46 is fixedly connected with the second feeding device 27 through the mounting seat 47, the guide sleeve 45 matched with the guide rail 46 is installed on the bracket 17, the bracket 17 is guided to slide in the width direction through the cooperation of the guide sleeve 45 and the guide rail 46, and the bracket 17 is driven to slide along the guide rail 46 when the first linear driver 48 acts, so as to adjust the transverse positions of the first rotary driver 40 and the second rotary driver 38, so that the fourth clutch 39 and the third clutch 34, the second clutch 41 and the first clutch 33 can be accurately aligned, engaged and separated, and the stability of the transmission connection is ensured.

[0037] As shown in Figure 5As shown, in some embodiments of the present application, an elastic buffer assembly is further mounted on the bracket 17, which includes a push plate 44, a spring 43 and a guide rod 42. The guide rod 42 is arranged in the second direction, one end of the guide rod 42 penetrates through the bracket 17 and is connected with a fixing bolt, and the guide rod 42 is sleeved with the spring 43, one end of the spring 43 abuts against the push plate 44, and the other end of the spring 43 abuts against the bracket 17.

[0038] When the bracket 17 moves towards the direction close to the second feeding device 27, the push plate 44 first contacts and compresses the spring 43, and the impact force is absorbed through the elastic deformation of the spring 43, and at the same time, the hoisting frame 28 on the other side is pushed to tightly abut against the inner side wall of the cross beam of the second feeding device 27, so as to horizontally position the hoisting frame 28, prevent deviation during the engagement of the clutch, and ensure the accuracy and stability of the transmission connection.

[0039] As shown in the drawings, Figure 1-2 In some embodiments of the present application, the top of the first feeding device 1 is provided with two oppositely arranged first cross beams 3, the length direction of the first cross beam 3 is in the second direction, and a first guide assembly is rotatably mounted between the first cross beams 3. The first guide assembly includes a plurality of first guide rollers 4, which are arranged in the length direction of the first cross beam 3 and are used for supporting and guiding the bottom of the material frame. The top surface height of the first guide roller 4 gradually decreases to form an inclined surface towards the second feeding device 27. The side of the second feeding device 27 close to the first feeding device 1 is provided with a limiting guide 5 in the height direction.

[0040] When the material frame is placed on the first guide roller 4, due to the design of the inclined surface, the material frame will slide towards the second feeding device 27 under the action of its own gravity and be limited in the limiting structure to realize automatic positioning. When the first feeding device 1 is lifted to be aligned with the second feeding device 27 and form a continuous feeding channel, the material frame can smoothly transition from the first feeding device 1 to the second feeding device 27, further improving the feeding efficiency and stability.

[0041] As shown in the drawings, Figure 1 In some specific embodiments of the present application, the end of the first cross beam 3 away from the second cross beam 16 is provided with a blocking rod 2, which is arranged in the width direction of the first feeding device 1 and is used for limiting the rear end of the material frame.

[0042] As shown in the drawings, Figure 1-2As shown, in some embodiments of the present application, the second feeding device 27 is provided with two second cross beams 16 arranged oppositely on the top, and a second guide assembly and a bearing platform 26 are installed between the second cross beams 16. Limiting grooves 25 are formed on the second cross beams 16, which are used to avoid the first limiting members 29. The height of the second cross beams 16 is higher than the top surface of the second guide assembly and the bearing platform 26. The second guide assembly includes a plurality of second guide rollers 7 which are rotatable and the length direction of the second guide rollers 7 is in the second direction. The height of the guide roller closest to the bearing platform 26 is slightly higher than the bottom height of the lifting frame 28.

[0043] When the lifting frame 28 is positioned, the first limiting members 29 are rotated into the limiting grooves 25 and finally clamped into the limiting grooves 25. The limiting grooves 25 can avoid the first limiting members 29 in the vertical direction and limit the lifting frame 28 in the length direction of the second feeding device 27. When the material frame enters the lifting frame 28, the first limiting members 29 cooperate with the limiting grooves 25 to avoid the lifting frame 28 from retreating. When the material frame enters the second feeding device 27, the bottom of the material frame contacts the second guide rollers 7 and slides along the surface of the second guide rollers 7. The rotation of the second guide rollers 7 reduces the frictional resistance between the material frame and the guide rollers, so that the material frame can smoothly enter the lifting frame 28.

[0044] As shown in the drawings, Figure 1 , Figure 6 In some embodiments of the present application, the lifting and conveying device includes a track, a walking mechanism and a lifting mechanism. The output end of the lifting mechanism is provided with a clamping arm 10. The clamping arm 10 is provided with a clamping part matched with the lifting frame 28. The clamping arm 10 is also provided with an eight-shaped flared portion 11 arranged downward. The lifting frame 28 is provided with guide rods 12 matched with the flared portion.

[0045] The clamping arm 10 first increases the relative distance. After the lifting frame 28 enters between the clamping arms 10, the clamping arms 10 gradually approach and tighten to accurately clamp the lifting frame 28 on both sides. The lifting frame 28 is provided with clamping discs 13 matched with the clamping part on both sides. The clamping discs 13 are provided with guide columns 15 perpendicular to the clamping discs 13 in the middle. The guide columns 15 cooperate with guide grooves 14 on the clamping part to form positioning grooves matched with the guide columns 15 at the bottom of the guide grooves 14. The clamping part can be automatically centered and locked when clamping the lifting frame 28 and lifting. When the lifting and conveying device lifts the lifting frame 28 to the second feeding device 27, the clamping arm 10 continues to move downward to press the guide rods 12 with the eight-shaped flared portion 11. After the guide rods 12 are stressed, the lifting frame 28 moves to the middle of the eight-shaped flared portion 11, so as to finely adjust the position of the lifting frame 28 in the length direction of the second feeding device 27, and ensure that the lifting frame 28 is accurately aligned with the second feeding device 27.
