[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0018] Embodiment 1

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4The utility model provides an auxiliary unloading mechanism for a falling machine, comprising two side plates 2, each of which is provided with a supporting plate 3; the supporting plate 3 comprises a moving block 32 and a supporting plate 31 hinged to the moving block 32, and each side wall of the two side plates 2 is provided with a moving groove, which is vertically arranged; the moving block 32 is slidingly arranged in the inner cavity of the moving groove, and a winding assembly 8 (comprising a winding rod, a pull rope wound on the outer wall of the winding rod, and a torsional spring arranged between the winding rod and the side plate 2) is arranged between the moving block 32 and the side plate 2, with one end of the pull rope away from the winding rod being connected to the moving block 32.

[0020] Please refer to Figure 3 and Figure 4 A locking assembly is arranged on the moving block 32, comprising a limiting rod 11 slidingly arranged on the moving block 32 and an elastic member (spring) connected to the limiting rod 11; the limiting rod 11 moves along the length extension direction of the supporting plate 31; a limiting groove 12 is arranged on the side wall of the supporting plate 31 facing the moving block 32, and one end of the limiting rod 11 facing the supporting plate 31 is inserted into the limiting groove 12 to fix the supporting plate 31; a slot 7 is arranged in the moving groove of the side plate 2, and the slot 7 is located below the moving block 32.

[0021] It should be noted that the falling machine 1 mainly comprises a frame, a door rotatingly arranged on the frame, and a motor for driving the door to rotate; when the product is transmitted to the falling machine 1, the product is located at the top of the door, and the door is driven downward by the motor to make the support of the product disappear, so that the product falls; the two side plates 2 are installed at the bottom of the frame of the falling machine 1, and the two side plates 2 are respectively located at the two sides of the door.

[0022] Working principle: when the falling machine 1 is opened, the product passes through the outlet of the falling machine 1 and falls above the two supporting plates 31, so that it moves downward under the action of gravity; when the moving block 32 moves to the slot 7, the limiting rod 11 is aligned with the slot 7, the limiting rod 11 moves under the action of the elastic member, one end of the limiting rod 11 is inserted into the slot 7, the other end of the limiting rod 11 is moved out of the limiting groove 12, the limitation on the supporting plate 31 is released, the supporting plate 31 rotates downward under the action of gravity to discharge, and the product of the supporting plate 31 falls onto the receiving equipment; when the gravity on the supporting plate 31 disappears, the winding assembly 8 (the torsional spring drives the winding rod to rotate reversely, and the pull rope is wound on the outer wall of the winding rod again) moves upward with the moving block 32 and the supporting plate 31 to reset.

[0023] It needs to be explained that the support plate 31 is hinged with the moving block 32 through the rotating shaft, and a spring is installed between the two, and the spring can make the downward rotating support plate 31 upwardly rotate and reset after the product is discharged; the top wall of the end of the limiting rod 11 away from the support plate 31 is a slope, and when the moving block 32 moves upwardly and resets, the slope of the limiting rod 11 contacts with the top inner wall of the slot 7, so that the limiting rod 11 is extruded to move in the direction of the support plate 31, so as to make the limiting rod 11 move out of the slot 7, and ensure that the moving block 32 and the support plate 31 can reset.

[0024] In the embodiment, as a further optimized scheme, please refer to Figure 2 、 Figure 3 and Figure 4 , the screw rod 5 is arranged on the support plate 31 and extends along the length direction of the support plate 31, the screw sleeve 9 is slidably arranged on the support plate 31 and is sleeved on the outer wall of the screw rod 5, the push plate 4 is arranged on the top wall of the screw sleeve 9, the rack 6 is arranged in the moving slot of the side plate 2 and is vertically arranged, the gear 10 is arranged at the end of the screw rod 5 and is engaged with the rack 6; when the moving block 32 and the support plate 31 are downwardly moved due to the product, the gear 10 moves on the rack 6, so that the screw rod 5 rotates and drives the screw sleeve 9 and the push plate 4 to move; the two push plates 4 are close to each other and push the product to move to the middle of the two support plates 31, so that the product can fall when the support plate 31 rotates downwardly, and the falling position of the product is accurate; when the moving block 32 moves upwardly and resets, the gear 10 reversely rotates, so that the screw sleeve 9 and the push plate 4 reset.

[0025] In the embodiment, as a further optimized scheme, please refer to Figure 3 , the bottom end of the rack 6 is located above the slot 7; when the limiting rod 11 is aligned with the slot 7, the gear 10 is not engaged with the rack 6, so that the rack 6 does not hinder the downward rotation of the support plate 31, and normal discharging is ensured.

[0026] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
