The reducer 680 in the descending loading and conveying device with a reducer proposed by the present invention has a speed change capability. After the product packaging box slips from the slideway 110, it enters the conveyor belt 650, and can slide down according to the frequency of falling (that is, the falling frequency per unit time). When the frequency is high, the running speed of the conveyor belt 650 is fast, and when the frequency is low, the running speed of the conveyor belt 650 is correspondingly slow, so that the running speed of the conveyor belt 650 is based on the product packaging box. It can be adjusted according to the density, which greatly enhances the practicability of the descending loading and conveying device with a reducer.

The speed regulation principle of the reducer 680 is as follows: the motor 710 drives the first rotating shaft 860 to rotate, the distance between the first sheave 870 on the telescopic assembly and the first rotating shaft 860 is elastically variable, and the plurality of first sheaves 870 here It is equivalent to a sheave that is fixedly sleeved on the first rotating shaft 860; after the first cylinder 740 and the second cylinder 840 are activated synchronously, the distance between the second rotating shaft 810 and the first rotating shaft 860 can be adjusted, because the first belt The circumference of 830 is fixed. When the distance between the second rotating shaft 810 and the first rotating shaft 860 increases, under the constraint of the first belt 830, the distance between the first sheave 870 and the first rotating shaft 860 becomes smaller, so that the transmission ratio between the first rotating shaft 860 and the second rotating shaft 810 becomes larger, and the rotation speed of the second rotating shaft 810 becomes smaller under the condition that the rotation speed of the motor 710 remains unchanged, so that the running speed of the conveyor belt 650 becomes slower. On the contrary, when the distance between the second rotating shaft 810 and the first rotating shaft 860 becomes smaller, under the constraint of the first belt 830, the distance between the first sheave 870 and the first rotating shaft 860 becomes larger, thereby The transmission ratio between the first rotating shaft 860 and the second rotating shaft 810 is reduced, and the rotating speed of the second rotating shaft 810 is increased under the condition that the rotating speed of the motor 710 remains unchanged, so that the running speed of the conveyor belt 650 becomes faster, so as to realize the adjustment speed function.

The radius of the second gear 730 is greater than the maximum distance between the first sheave 870 and the first rotating shaft 860 ; the diameter of the third sheave 750 is smaller than the diameter of the second sheave 820 .

Through the above technical solutions, the structure and function of the reducer 680 are improved.

In practical application, due to the limitation of factory space, the above-mentioned slideway 110 can only transport product packaging boxes in the form of short distance and large gradient. It will rush out of the collection port, which will cause certain impact damage to the product and the packaging box, affecting the quality of the product.

To this end, as shown in FIG. 1 and FIG. 4 , the present invention proposes a descending loading and conveying device with a reducer, further comprising a buffer assembly disposed on the side of the slideway 110 facing the ground, and the buffer assembly is close to the lower end 140 The buffer assembly includes a moving frame, a third guide rod 580, a fourth guide rod 610, a first electric push rod 620, a fifth guide rod 550, a first sleeve 530, a contact seat 540 and a third spring 560.
