[0014] The beneficial effects of this utility model are as follows: By setting up a transfer frame, the upper slide rail tilts backwards and upwards, and the material is automatically fed onto the transfer frame. The material is on the transfer frame, and under the action of the material's gravity, the transfer frame moves downwards to one side of the lower slide rail. During the downward movement of the transfer frame, a separating device blocks the material, preventing it from sliding further backwards. When the transfer frame moves to dock with the lower slide rail, a linkage device is triggered. The linkage device drives the transfer frame, causing it to tilt, allowing the material to slide from the transfer frame onto the lower slide rail.

Detailed Implementation Methods

[0017] To simplify the structure and facilitate installation, the transfer frame 21 includes a sliding seat 23 that can slide up and down along the mounting frame 2 and a receiving platform 24 that is rotatably mounted on the sliding seat 23 and can be driven to rotate counterclockwise by the material when it slides down from the upper slide rail 31. When the sliding seat 23 slides down to the receiving platform 24 and docks with the lower slide rail 32, the linkage device 5 drives the receiving platform 24 to rotate clockwise. The clockwise and counterclockwise directions are relative directions in the figure, which are only relative directions for the convenience of description and are not time-limited directions. The receiving platform 24 is a flat plate that is hinged to the sliding seat 23 in the middle. The end of the receiving platform 24 that is close to or away from the upper frame 3 or the lower frame 4 can swing up and down around the hinge axis. For ease of description, the state in which the end of the receiving platform 24 closest to the upper shelf 3 or the lower shelf 4 is higher than the end of the receiving platform 24 furthest from the upper shelf 3 or the lower shelf 4 is defined as the first state, and the state in which the end of the receiving platform 24 closest to the upper shelf 3 or the lower shelf 4 is lower than the end of the receiving platform 24 furthest from the upper shelf 3 or the lower shelf 4 is defined as the second state. When the material slides from the upper slide 31 to the receiving platform 24, under the action of the material's inertia and gravity, it will drive the receiving platform 24 to rotate counterclockwise to the first state. When the receiving platform 24 triggers the linkage device 5 downward, the linkage device 5 will drive the receiving platform 24 to rotate clockwise to the second state. In the second state, the receiving platform 24 is tilted, and the material slides down to the lower slide 32 under the action of gravity. The mounting frame 2 is provided with a vertically extending guide groove 29. One end of the guide groove 29 near the upper shelf 3 or lower shelf 4 has a vertically extending opening, the width of which is less than the width of the guide groove 29. The elastic element 22 is a spring, with its upper end fixed inside the top of the guide groove 29 and its lower end fixed to the guide rail 30. The distance the receiving platform 24 slides between the upper shelf 3 and the lower shelf 4 is equal to the distance between the upper shelf 3 and the lower shelf 4. Considering the weight of the object and the spring's elastic coefficient, it can satisfy the requirement that under the object's gravity, the length of the elastic deformation of the spring caused by the receiving platform 24 is equal to the distance between the upper shelf 3 and the lower shelf 4. The transfer frame 21 is provided with a guide rail 30 that extends into the guide groove 29 and slides vertically along the guide groove 29. Both ends of the guide rail 30 extend to the width of the guide groove 29. The width of the guide rail 30 is greater than the opening width of the guide groove 29, preventing the guide rail 30 from being pulled out of the opening of the guide groove 29. For convenient guidance, the guide rail 30 has two horizontally arranged guide posts, which are spaced apart vertically to balance the sliding seat 23 and reduce the friction between the guide rail 30 and the guide groove 29. The mounting frame 2 is provided with an upper stop block 14 that can block the transfer frame 21 from moving upward when it is connected to the upper slide rail 31, and a lower stop block 15 that can block the transfer frame 21 from moving downward when it is connected to the lower slide rail 32. The upper stop block 14 and the lower stop block 15 respectively restrict the vertical position of the transfer frame 21. When the transfer frame 21 is located in the position of the upper slide rail 31, the elastic element 22 still has a certain elastic tension.

[0018] Specifically, the linkage device 5 includes a linkage block 51 rotatably mounted on the sliding seat 23. One end of the linkage block 51 is provided with a push end 55 that can rotate the receiving platform 24 clockwise. The pivot of the linkage block 51 is in the middle. The mounting frame 2 is provided with a lower boss 52 that can push the linkage block 51 to rotate when the receiving platform 24 slides down and docks with the sliding track 32, causing the push end 55 to push the receiving platform 24 to rotate clockwise. The upper surface of the lower boss 52 is inclined, and the inclined surface presses the end of the linkage block 51 near the bottom of the receiving platform 24. That is, the lower boss 52 pushes the end of the linkage block 51 near the bottom of the receiving platform 24 to rotate upward, thereby pushing the receiving platform 24 to rotate to the second state, causing the receiving platform 24 to tilt towards the sliding track 32. The material slides down to the sliding track 32 under the action of gravity. The mounting frame 2 is also equipped with an upper boss 54. The other end of the linkage block 51 is equipped with a hook 56 that can be squeezed and rotated by the upper boss 54 when the receiving platform 24 slides upward and aligns with the upper slide rail 31. The hook 56 rotates to one side of the upper slide rail 31. A return spring 53 is provided between the sliding seat 23 and the linkage block 51, which can spring the linkage block 51 to rotate and reset, allowing the hook 56 to engage with the upper end of the upper boss 54. When the transfer frame 21 slides upward and squeezes against the upper boss 54, the linkage block 51 is squeezed and rotated, thus compressing the return spring 53. When the upper end of the hook 56 moves upward to the upper end of the upper boss 54, the return spring 53 recovers its deformation and springs the linkage block 51 to rotate, allowing the hook 56 to press against the upper end of the upper boss 54, thereby enabling… The supporting linkage block 51 positions the sliding seat 23, preventing it from sliding downwards. This allows the material to be stably received when it slides from the upper slide 31 onto the receiving platform 24. The platform is only unlocked after the material has stabilized and moved to the side, causing the receiving platform 24 to rotate. When the material slides from the upper slide 31 onto the receiving platform 24 and causes it to rotate, the receiving platform 24 pushes the push end 55 to separate the hook 56 from the upper boss 54. When the material slides from the upper slide 31 onto the receiving platform 24, the receiving platform 24 rotates counterclockwise, squeezing the lower end of the linkage block 51, causing the linkage block 51 to rotate clockwise. This causes the upper end of the hook 56 to move away from the upper boss 54, thus unlocking the platform and allowing the sliding seat 23 to slide downwards.The linkage block 51 is hinged to the sliding seat 23 at its center, and the receiving platform 24 is hinged to the sliding seat 23 at its center. The pushing end 55 extends below the receiving platform 24. When the pushing end 55 rotates upward, it pushes the receiving platform 24 to rotate clockwise. It is positioned on the upper end of the upper boss 54 by the hook 56, so that the upper boss 54 supports the linkage block 51. The return spring 53 is a torsion spring. One end of the torsion spring presses against the sliding seat 23, and the other end presses against one side of the hook 56. The upper boss 54 is provided with a return spring when the sliding seat 23 is in use. When the device moves upward, it can compress the first inclined surface 58, which can squeeze the hook 56 to rotate and compress the torsion spring. The hook 56 is provided with an inclined surface that can squeeze the first inclined surface 58. The first inclined surface 58 is inclined upward from the side near the mounting bracket 2 to the side of the upper shelf 31. The upper end face of the lower boss 52 is provided with a second inclined surface 59, which can support and push the linkage block 51 to rotate, so that the push end 55 pushes the receiving platform 24 to rotate clockwise. The second inclined surface 59 is inclined downward from the side near the mounting bracket 2 to the side of the lower shelf 32. An anti-rotation mechanism is provided between the sliding seat 23 and the receiving platform 24 to block the receiving platform 24 when it rotates clockwise. The anti-rotation mechanism includes a positioning protrusion 20 on the side of the receiving platform 24 near the mounting frame 2 and a positioning groove 231 on the sliding seat 23 for the positioning protrusion 20 to extend into and block the upward rotation of the positioning protrusion 20. The positioning groove 231 limits the clockwise rotation angle of the receiving platform 24. The counterclockwise rotation angle of the receiving platform 24 is limited by the support linkage block 51. The push end 55 has a hook shape. When the receiving platform 24 rotates counterclockwise, the hook shape of the push end 55 hooks the bottom edge of the receiving platform 24. The sliding seat 23 has two oppositely spaced protrusions 232 on one end face near the mounting frame 2. The two ends of the shaft 57 of the linkage block 51 are respectively inserted into the two protrusions 232. The sliding seat 23 has a notch 233 between the two protrusions 232 for the linkage block 51 to pass through, which facilitates the installation of the linkage block 51. The linkage block 51 is installed at the bottom corner of the receiving platform 24.

[0019] The separating device 6 includes a mounting base 61 fixed on the mounting frame 2. The mounting base 61 is provided with a baffle 62 that can be moved up and down by the transfer frame 21. The baffle 62 is provided with a baffle bar 63 that can move to the side of the material to block the material when the baffle 62 moves downward and can deviate from the material to release the obstruction when the baffle 62 moves upward. When the baffle bar 63 moves upward, it is higher than the material, thus releasing the obstruction. When the baffle bar 63 moves downward, it is between the two materials, thus holding back the material on the front side, while the material on the rear side is on the receiving platform 24. The mounting base 61 is provided with a guide groove 64 for the baffle 62 to pass through and for guiding the baffle 62 to move up and down. The end of the baffle 62 away from the baffle 62 is provided with an elastic fastening end 60. The transfer frame 21 is provided with a push buckle 25 that can push the baffle 62 upward and engage with the elastic fastening end 60 when the transfer frame 21 moves upward, and can drive the baffle 62 downward and separate it from the elastic fastening end 60 when the transfer frame 21 moves downward. When the transfer frame 21 moves upward, the push buckle... As push-button 25 moves upward, it contacts the elastic engaging end 60, pushing against it and causing the stop 62 to move upward. When the stop 62 reaches the top of the guide groove 64, the elastic engaging end 60 and push-button 25 are elastically pressed together and locked. When the transfer frame 21 moves downward, push-button 25 causes the stop 62 to move downward. When the stop 62 is blocked from moving downward, the elastic engaging end 60 separates from push-button 25. The stop 62 is rod-shaped, with a horizontal rod 68 connected to one end of the stop rod 63 and extending forward, and an inclined rod 69 connected to one end of the horizontal rod 68. The stop rod 63 extends horizontally along the width of the upper slide rail 31. The elastic fastening end 60 is provided at the end of the inclined rod 69. The elastic fastening end 60 includes a compression protrusion 65 formed by bending a rod and a pressure rod 66 provided at the end of the compression protrusion 65. A first fastening groove 67 is formed between the pressure rod 66 and the compression protrusion 65. The push fastening 25 includes a vertically extending push rod 26 whose upper end can abut against the pressure rod 66. The upper part of the push rod 26 is provided with a second fastening groove 27 with a side opening for the compression protrusion 65 to fasten. The upper protruding edge 28 of the second fastening groove 27 is inserted into the first fastening groove 67. The pressure rod 66 presses against the top of the top push rod 26. The mounting base 61 is provided with an inclined boss 70 that can block the inclined rod 69 when the stop 62 moves downward. The inclined boss 70 prevents the stop 62 from rotating and prevents the stop 62 from moving out of the guide groove 64.

[0020] The support device 1 includes multiple vertically extending columns 11 fixed inside the cabinet 10. Four columns 11 are provided, two on each of the two opposite side walls of the cabinet 10.
