An installation frame 6 is fixedly arranged on the lower inner wall of the frame 1. The support frame 7-1 is fixedly arranged on the upper side wall of the installation frame 6. The support platform 7-2 is rotatably arranged on the support frame 7-1 through a rotating shaft. A support pneumatic rod 7-3 is fixedly arranged on the support frame 7-1. A support seat 7-4 is fixedly arranged on the output shaft of the support pneumatic rod 7-3. A support arm 7-5 is rotatably arranged on the support seat 7-4 through a rotating shaft, and the upper end of the support arm 7-5 is rotatably arranged on the movable end of the support platform 7-2 through a rotating shaft. Two guiding slide rails 22 which are symmetrically arranged front and back are fixedly arranged on the support frame 7-1. A guiding slider 23 is integrally formed on the support seat 7-4, and the guiding slider 23 is slidably arranged between the two front and back guiding slide rails 22. Two guiding frames 16 are fixedly arranged on the lower side wall of the material loading tray 2. A stepping seat 17 is arranged between the left and right guiding frames 16. Guide rods 18 are fixedly arranged on the left and right side walls of the stepping seat 17, and the guide rods 18 are movably inserted into the guiding frames 16. A return spring 19 is sleeved on the right guide rod 18, and the return spring 19 is clamped between the stepping seat 17 and the right guiding frame 16. A guiding groove 20 is integrally formed on the stepping seat 17, and the right end of the guiding groove 20 is inclined downward. A connecting rod 21 is fixedly arranged on the connecting arm 4, and the connecting rod 21 is movably inserted into the guiding groove 20. The described positioning mechanism 8 includes a rotating seat 8-2 and a limiting arm 8-3. An installation seat 8-1 is fixedly arranged on the upper side wall of the installation frame 6. The rotating seat 8-2 is rotatably arranged through a rotating shaft. The limiting arm 8-3 is inserted into the rotating seat 8-2. A limiting shaft 24 is fixedly arranged at one end of the limiting arm 8-3 located inside the rotating seat 8-2, and the limiting shaft 24 is rotatably arranged on the inner side wall of the rotating seat 8-2 through a bearing. A return torsion spring 25 is sleeved on the limiting shaft 24. One leg of the return torsion spring 25 is fixedly arranged on the limiting arm 8-3, and the other leg of the return torsion spring 25 is fixedly arranged on the inner wall of the rotating seat 8-2. A bearing platform 8-4 is fixedly arranged on the lower side wall of the material loading tray 2, and the bearing platform 8-4 is arranged to the right of the right guiding frame 16. A limiting pneumatic rod 26 is fixedly arranged on the support frame 7-1. A stepping rack 27 is fixedly arranged on the output shaft of the limiting pneumatic rod 26, and the stepping rack 27 is movably abutted against the upper side wall of the installation frame 6. A stepping gear 28 with a special-shaped structure concentric with the rotating seat 8-2 is fixedly arranged on the outer side wall of the rotating seat 8-2, and the stepping rack 27 is meshed with the lower side of the stepping gear 28.

[0025] When using this device, in the stepping mode of the loading tray 2, the supporting pneumatic rod 7-3 pushes the supporting seat 7-4 to the left end of the guiding slide rail 22, so that the supporting seat 7-4 pulls the supporting platform 7-2 flat through the supporting arm 7-5. The supporting platform 7-2 is arranged lower than the stepping seat 17. The limiting pneumatic rod 26 retracts and pulls the stepping gear 28 through the stepping rack 27, thereby driving the limiting arm 8-3 in the rotating seat 8-2 to be placed flat. The limiting arm 8-3 is arranged lower than the stepping seat 17. The return spring 19 pushes the stepping seat 17 to the left end of the stroke of the stepping seat 17, and the pressing torsion spring 14 pushes the connecting arm 4 to drop, so that the connecting rod 21 on the connecting arm 4 is located at the lower right end of the guiding groove 20 on the stepping seat 17. The connecting arm 4 drops and pushes the connecting pawl 5 against the chain of the chain stepping unit 3, so that the chain stepping unit 3 drives the loading tray 2 to move through the connecting arm 4 and the connecting frame 13. The loading tray 2 slides in the main slide rail 9 on the frame 1 through its secondary slide rail 10, and slides forward to the left through the pulley 11 in the main slide rail 9, realizing the forward conveying of materials through the loading tray 2; When pausing the forward movement of the material, taking the mounting bracket 6 as a stationary reference, when the loading tray 2 has not moved forward above the mounting bracket 6, the support pneumatic rod 7-3 is used to pull the support seat 7-4 to the right. The support seat 7-4 pushes the support platform 7-2 to lift through the support arm 7-5, so that the support platform 7-2 is higher than the lower side edge of the stepping seat 17. After the loading tray 2 moves to above the mounting bracket 6 and the stepping seat 17 contacts the lifted support platform 7-2, as the loading tray 2 continues to move to the left, the stepping seat 17 is supported by the support platform 7-2 so that the stepping seat 17 is in a stationary state relative to the mounting bracket 6. The loading tray 2 drives the connecting frame 13 to move to the left, and the connecting frame 13 drives the connecting arm 4 and the connecting ratchet 5 to move to the left. The connecting arm 4 moves to the left and thus drives the connecting rod 21 thereon to slide to the left in the guide groove 20 on the stepping seat 17. While the connecting rod 21 slides to the left, it rises and pushes the connecting arm 4 to lift, so that the connecting arm 4 drives the connecting ratchet 5 thereon to lift, making the connecting ratchet 5 disengage from the chain of the chain stepping unit 3. After the connecting ratchet 5 disengages from the chain stepping unit 3, the loading tray 2 loses the drive to move to the left and thus stops moving to the left. During the process of the connecting arm 4 lifting, the downward pressure torsion spring 14 on the connecting shaft 12 at the upper end of the connecting arm 4 winds up the holding force, and the tension spring 15 pulls the right end of the connecting ratchet 5 to rotate upward until it is limited. The right guide frame 16 moves closer to the stepping seat 17, thereby pressing the return spring 19 on the right guide rod 18 to wind up the holding force; then the limit pneumatic rod 26 is used to push the stepping rack 27 to the right. The stepping rack 27 drives the rotating seat 8-2 to rotate through the stepping gear 28, so that the rotating seat 8-2 drives the limit arm 8-3 to lift, making the limit arm 8-3 abut against the bearing platform 8-4, and continuing to rotate the rotating seat 8-2, so that the limit arm 8-3 pushes the bearing platform 8-4 and drives the loading tray 2 to continue to move to the left until the limit arm 8-3 completely abuts against the bearing platform 8-4 and the return torsion spring 25 on the limit shaft 24 winds up the holding force, and the stepping seat 17 completely abuts against the support platform 7-2 and makes the stepping seat 17 completely press the return spring 19 against the right guide frame 16, that is, the precise positioning of the loading tray 2 is completed; When the loading tray 2 is released, the support platform 7-2 is lowered in sequence. Thus, the return spring 19 pushes the stepping base 17 to move leftward for resetting, and the downward pressure torsion spring 14 pushes the connecting arm 4 to rotate downward for resetting. The connecting arm 4 pushes the connecting ratchet 5 downward and makes the connecting ratchet 5 catch the chain of the chain stepping unit 3. Then, the chain stepping unit 3 continues to drive the loading tray 2 to move leftward; during the process of the support platform 7-2 being lowered until the connecting ratchet 5 engages with the chain stepping unit 3, after the support platform 7-2 is lowered, the limit on the stepping base 17 is lost, that is, the limit on the loading tray 2 is regarded as lost. Then, the limit arm 8-3 against the bearing platform 8-4 releases potential energy through the return torsion spring 25 on the limit shaft 24 to push the limit arm 8-3, so that the upper end of the limit arm 8-3 rotates leftward and moves. Thus, the limit arm 8-3 pushes the bearing platform 8-4, and through the bearing platform 8-4, the loading tray 2 is pushed leftward, so that the loading tray 2 has an initial speed moving in the same direction as the chain stepping unit 3 when docking with the chain stepping unit 3. Then, after the loading tray 2 moves out from above the mounting frame 6, the limit pneumatic rod 26 pulls the stepping rack 27 leftward, thereby driving the rotating seat 8-2 and the limit arm 8-3 to rotate rightward and flatten for resetting.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The device is provided with a connecting arm 4 inclined downward along the moving direction of the chain stepping unit 3, and the connecting ratchet 5 is buckled on the chain stepping unit 3 through the connecting arm 4. Thus, the connection and disconnection with the chain stepping unit 3 are realized by the lifting and lowering of the connecting arm 4, that is, the accumulation of the loading tray 2 is realized. Moreover, the connecting arm 4 arranged in this inclined manner is beneficial to the disengagement of the connecting ratchet 5 from the chain stepping unit 3, and the problem of the connecting ratchet 5 being stuck will not occur; 2. Based on the connecting arm 4 arranged with a reverse bending joint, the device is provided with a stepping base 17 with an inclined guide groove 20 and a support platform 7-2 that can be lifted and lowered. Thus, the support platform 7-2 is erected to intercept the stepping base 17, and then the cooperation between the stepping base 17 and the connecting rod 21 is used to push the connecting arm 4 to lift, so as to stop the loading tray 2; 3. The device is also provided with a limit arm 8-3 on the mounting frame 6 through the rotating seat 8-2, and in cooperation with the bearing platform 8-4 on the loading tray 2, after the loading tray 2 is intercepted by the support platform 7-2, the limit arm 8-3 is lifted and pushed to realize the precise positioning of the loading tray 2.

[0027] For those skilled in the art, they can modify the technical solutions recorded in the foregoing embodiments and make equivalent replacements for some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
