Detailed Implementation

[0047] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0048] like Figures 1 to 7 As shown, an automatic stacking and receiving machine 100 according to an embodiment of the present utility model includes a frame 1, a feeding conveyor belt 2, a discharging belt 3, a lifting assembly 4, a blocking assembly 5, and a pushing assembly 6.

[0049] The frame 1 extends along the first direction X, and the feeding conveyor belt 2 and the discharging conveyor belt 3 are spaced apart on the frame 1 along the first direction X; and the feeding conveyor belt 2 is located above the discharging conveyor belt 3.

[0050] The lifting assembly 4 includes a lifting platform 41, which is movable between a receiving position and a pushing position. The receiving position is located above the pushing position and below the discharge end of the feeding conveyor belt 2. The pushing position is located in front of the feeding end of the discharge belt 3.

[0051] The material blocking assembly 5 includes a material receiving platform 50 located at the material receiving position. The material receiving platform 50 can be opened and closed so that the material can fall onto the lifting platform 41 or be received by the material.

[0052] The pushing assembly 6 includes a pushing plate 61, which can move back and forth along the first direction X to push the material on the lifting platform 41 from the pushing position to the discharge belt 3.

[0053] When the lifting platform 41 is in the receiving position, the receiving platform 50 can open to allow the material to fall onto the lifting platform 41; when the lifting platform 41 is not in the receiving position, the receiving platform 50 closes to receive the material falling from the feeding conveyor belt 2.

[0054] Based on the above technical solution, when the lifting platform 41 is in the receiving position, the receiving platform 50 opens, and the material falls onto the lifting platform 41; after receiving a certain amount of material, the lifting platform 41 completes the stacking of the material; then it moves from the receiving position to the pushing position, and when the lifting platform 41 is not in the receiving position, the receiving platform 50 closes to receive the material falling from the feeding conveyor belt 2; after the lifting platform 41 moves to the pushing position, the pushing plate 61 moves back and forth along the first direction X to push the material on the lifting platform 41 from the pushing position onto the discharge belt 3; thereby completing the pushing out of the stacked material, and then realizing the stacking and receiving of the material. The pusher plate 61 moves forward and resets along the first direction X, and the lifting platform moves towards the receiving position to start the next receiving operation. Thus, through the coordinated operation of the feeding conveyor belt 2, the lifting assembly 4, the blocking assembly 5, and the pusher assembly 6, the automatic stacking and receiving machine 100 can collect and stack a set number of materials in each operation, thereby automating the stacking and receiving process, improving efficiency, and reducing labor costs. Furthermore, the receiving platform 50 and the lifting platform 41 are used to temporarily place stacked materials, accommodating materials of different specifications and shapes, facilitating expanded use.

[0057] Furthermore, the material blocking assembly 5 also includes a limiting member 55, which is located in the discharge direction of the feeding conveyor belt 2 and is used to block the material and cause the material to fall onto the receiving platform 50 or the lifting platform 41.

[0058] Preferably, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, to limit materials of various sizes and specifications so that they can be stacked properly and prevented from shifting when falling onto the receiving platform 50, the limiting component 55 includes a limiting guide rail 551, a connecting plate 552, and a limiting plate 553; the two limiting guide rails 551 are spaced apart and extend parallel to each other along the first direction X, and the two ends of the connecting plate 552 are respectively movably connected to the two limiting guide rails 551; the limiting plate 553 is fixed on the connecting plate 552 and extends vertically in the receiving platform 50.

[0059] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, to enable the first stopper 51 and the second stopper 52 to move closer to or further away from each other, the stopper assembly 5 further includes a first stopper driving mechanism 53 and a second stopper driving mechanism 54. The first stopper driving mechanism 53 is connected to the frame 1, and the first stopper 51 is connected to the output end of the first stopper driving mechanism 53. The first stopper driving mechanism 53 is used to drive the first stopper 51 to move back and forth in the first direction X. The second stopper driving mechanism 54 is connected to the frame 1, and the second stopper 52 is connected to the output end of the second stopper driving mechanism 54. The second stopper driving mechanism 54 is used to drive the second stopper 52 to move back and forth in the first direction X.

[0060] Preferably, the receiving platform 50 is designed to open when the lifting platform 41 is in the receiving position, allowing the material to fall onto the lifting platform 41; when the lifting platform 41 is not in the receiving position, the receiving platform 50 is closed to receive the material falling from the feeding conveyor belt 2; a first sensor is provided at the receiving position to detect whether the lifting platform 41 is in the receiving position; the first sensor is electrically connected to the first blocking drive mechanism 53 and the second blocking drive mechanism 54 to transmit the detection signal to the first blocking drive mechanism 53 and the second blocking drive mechanism 54, thereby controlling the movement of the first blocking component 51 and the second blocking component 52 through the first blocking drive mechanism 53 and the second blocking drive mechanism 54.

[0061] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in order to enable the pusher plate 61 to move back and forth in the first direction X, the pusher assembly 6 further includes a pusher drive mechanism 62; the pusher plate 61 is connected to the output end of the pusher drive mechanism 62, the pusher drive mechanism 62 is connected to the frame 1, and the pusher drive mechanism 62 is used to push the pusher plate 61 to move back and forth in the first direction X.

[0062] Similarly, in order to enable the pushing drive mechanism 62 to drive the pushing plate 61 to move back and forth in the first direction X when the lifting platform 41 is in the pushing position, a second sensor is provided at the pushing position. The second sensor is used to detect whether the lifting platform 41 is in the pushing position. The second sensor is electrically connected to the pushing drive mechanism 62 to transmit the detection signal to the pushing drive mechanism 62.

[0063] Preferably, in this embodiment, the first material blocking drive mechanism 53, the second material blocking drive mechanism 54 and the pusher drive mechanism 62 are all cylinders, which drive the first material blocking component 51, the second material blocking component 52 and the pusher plate 61 respectively. In other embodiments, other drive mechanisms can be selected so that the first material blocking component 51, the second material blocking component 52 and the pusher plate 61 can perform linear reciprocating motion.

[0064] Furthermore, such as Figure 1 , Figure 2 and Figure 7 As shown, it also includes a guide component 7; the guide component 7 includes a bracket 71, a first guardrail 72, and a second guardrail 73. The bracket 71 is mounted on the feeding conveyor belt 2; the two first guardrails 72 are spaced apart and parallel in the second direction Y, and extend along the first direction X, and are movably connected to the bracket 71; thereby, the two spaced first guardrails 72 guide the material's movement on the feeding conveyor belt 2, ensuring the material moves between the two first guardrails 72, thus ensuring subsequent stacking. The two second guardrails 73 are spaced apart and parallel in the second direction Y, and extend vertically towards the receiving position, and are movably connected to the bracket 71 along the second direction Y; wherein, the first direction X and the second direction Y are perpendicular to each other in the horizontal plane. The two second guardrails 73 extending towards the receiving platform 50 guide the correct descent and stacking of the material.

[0065] Furthermore, such as Figure 1 , Figure 2 and Figure 7 As shown, to achieve a movable connection between the first guardrail 72 and the support 71, allowing the first guardrail 72 to be adjusted to accommodate materials of different specifications, the guide assembly 7 further includes a first guide slider 74; the support 71 includes two uprights 711 spaced apart along the first direction X; the uprights 711 are mounted on the feeding conveyor belt 2, and each upright 711 has a first guide rail 712 on one side of the first direction X; two first guide sliders 74 are spaced apart on the first guardrail 72 along the first direction X; the first guide sliders 74 are slidably connected to the first guide rails 712 in a one-to-one correspondence. This allows the spacing between the two first guardrails 72 to be adjusted by adjusting the first guide sliders 74 to accommodate materials of different specifications.

[0066] Furthermore, such as Figure 1 , Figure 2 and Figure 7As shown, similar to the above configuration, to specifically achieve a movable connection between the second guardrail 73 and the support 71, so that the second guardrail 73 can be adjusted to accommodate materials of different specifications; the guide assembly 7 also includes a second guide slider 75; the upright 711 near the lifting platform 41 has a second guide rail 713 on the side opposite to the first guide rail 712; the second guardrail 73 is slidably connected to the second guide rail 713 via the second guide slider 75. This allows the spacing between the two second guardrails 73 to be adjusted by adjusting the second guide slider 75 to accommodate materials of different specifications.

[0067] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, to enable the lifting platform 41 to move between the receiving position and the pushing position, the lifting assembly 4 further includes a lifting plate 42 and a lifting drive mechanism 43. The lifting plate 42 extends vertically, and a lifting slide rail 421 extending vertically is fixedly mounted on the lifting plate 42. One end of the lifting platform 41 has an opening 410, and the lifting platform 41 is movably connected to the lifting slide rail 421 through the opening 410. The lifting drive mechanism 43 includes a lifting screw 431, a lifting slider 432, and a lifting motor 433. The lifting screw 431 is parallel to and spaced apart from the lifting slide rail 421, and is rotatably connected to the lifting plate 42. The lifting slider 432 is sleeved on the outer periphery of the lifting screw 431 and screwed to the lifting screw 431. The lifting slider 432 is also fixedly connected to the lifting platform 41. The lifting motor 433 is connected to the lifting plate 42 and is used to drive the lifting screw 431 to rotate.

[0068] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, in order to limit the material and prevent the material from moving during the descent of the lifting platform 41, thereby causing problems such as unstable stacking, the top surface of the lifting platform 41 is provided with a limiting block 411.

[0069] Furthermore, such as Figures 1-3 As shown, to facilitate the pushing action of the pusher plate 61, so that the pushing action of the pusher plate 61 can drive the movement of multiple stacks of material on the discharge belt 3, the discharge belt 3 includes a discharge frame 31 and flow bars 32; multiple flow bars 32 extend along the first direction X and are installed on the discharge frame 31; the pushing position is located in front of the feeding end of the flow bars 32. This allows the pusher plate 61 to push the stacked material onto the flow bars 32 when the lifting platform 41 is in the pushing position.

[0070] The working process of this utility model is as follows: the feeding conveyor belt 2 is started, and the material moves from front to back along the first direction X under the drive of the feeding conveyor belt 2.

[0071] Materials fall sequentially into the receiving platform 50 and stack themselves. The lifting platform 41 rises to the receiving position. The first blocking drive mechanism 53 and the second blocking drive mechanism 54 drive the first blocking component 51 and the second blocking component 52 respectively, so that they move away from each other, thereby opening the receiving platform 50 and allowing materials to fall onto the lifting platform 41. Subsequent materials are then stacked onto the already stacked materials.

[0072] When the lifting platform 41 receives a set amount of material, the lifting platform 41 begins to descend. At the same time, the first material blocking drive mechanism 53 and the second material blocking drive mechanism 54 respectively drive the first material blocking component 51 and the second material blocking component 52 to move closer to each other, thereby causing the receiving platform 50 to close, and the material falls and stays in the receiving platform 50.

[0073] The lifting platform 41 lowers the material to the pushing position, and the pushing drive mechanism 62 drives the pushing plate 61 to push the material on the lifting platform 41 onto the flow strip 32.

[0074] In summary, this utility model embodiment provides an automatic stacking and receiving machine 100, which includes a frame 1, a feeding conveyor belt 2, a discharging belt 3, a lifting assembly 4, a blocking assembly 5, and a pushing assembly 6. When the lifting platform 41 is in the receiving position, the receiving platform 50 opens, and the material falls onto the lifting platform 41. After receiving a certain amount of material, the lifting platform 41 completes the stacking of the material. Then it moves from the receiving position to the pushing position, and when the lifting platform 41 is not in the receiving position, the receiving platform 50 closes to receive the material falling from the feeding conveyor belt 2. After the lifting platform 41 moves to the pushing position, the pushing plate 61 moves back and forth along the first direction X to push the material on the lifting platform 41 from the pushing position onto the discharging belt 3, thereby completing the pushing out of the stacked material and realizing the stacking and receiving of the material. The pusher plate 61 moves forward and resets along the first direction X, and the lifting platform moves towards the receiving position to start the next receiving operation. Thus, through the coordinated operation of the feeding conveyor belt 2, the lifting assembly 4, the blocking assembly 5, and the pusher assembly 6, the automatic stacking and receiving machine 100 can collect and stack a set number of materials in each operation, thereby automating the stacking and receiving process, improving efficiency, and reducing labor costs. Furthermore, the receiving platform 50 and the lifting platform 41 are used to temporarily place stacked materials, accommodating materials of different specifications and shapes, facilitating expanded use.

[0075] The above description is only a preferred embodiment of the present utility model.
