The effect of the angle-changing connecting rod group arranged here is that the arc-shaped guide grooves 31 of the inner ends of the connecting support rods 28 on the two sides can rotate and slide around the corresponding convex columns 32 through the change of the overall weight of the receiving hopper 26, so that the purpose of controlling the change of the inclination angle of the whole receiving hopper 26 is achieved, the continuous backward movement of the receiving opening 27 at the top of the receiving hopper 26 is finally realized, the deep-fried dough sticks falling into the receiving hopper 26 are ensured to be continuously piled up at the bottom, the piling up quantity of the deep-fried dough sticks in the receiving hopper 26 is ensured, and the available storage capacity of the receiving hopper 26 is improved.

The specific working principle is as follows: starting an electric heating pipe to heat oil in the frying cavity 2, after the oil temperature rises to a proper temperature, placing a green deep-fried dough stick 3 of the green deep-fried dough stick 3 on a conveying fork 17 of each conveying piece A above the oil surface under the manual sequential phase operation state,

with the conveyor a running downwards, the green deep-fried dough sticks 3 move downwards and are immersed under the hot oil to keep the oil inside immersed for frying, and after about 10 seconds, the green deep-fried dough sticks 3 are heated to generate bubbles, and start to float.

Then, the deep-fried dough sticks are pressed downwards by the conveying fork 17 of the conveying member A and kept below the oil, and after the deep-fried dough sticks pass through the corner, the conveying fork 17 of the conveying member A adjacent above presses the deep-fried dough sticks in an upward floating state and makes the deep-fried dough sticks move upwards. During the process, the deep-fried dough sticks start to expand, become golden yellow, generate crisp crust and are shaped.

As the fork is lifted, the deep-fried dough sticks are separated from the oil surface, the buoyancy is lost, at the moment, the upward operation of the conveying fork 17 of the conveying part A adjacent below is changed into the upward movement of the upward supporting deep-fried dough sticks, the deep-fried dough sticks in the upward operation state are gradually cooled, and the oil draining is completed.

As the conveying fork 17 of the conveying member a continues to rise, the deep-fried dough sticks reach the top end in the vertical direction. At this point, the reverse rotation of the index fork 22, which is just turned on, pushes the deep-fried dough stick product 34 outwardly out of the feed fork 17 and into the receiving hopper 26.

The steps are repeated, as the deep-fried dough sticks 34 continuously enter the receiving hopper 26 and are accumulated at the bottom of the receiving hopper 26, the angle-changing connecting rod groups at the two ends of the whole receiving hopper 26 can rotate and shift along the raised columns 32 by means of the corresponding hinge shaft 33 points and the arc-shaped guide grooves 31 at the two sides under the action of gravity stirring, the continuous upwarping of the receiving hopper 26 is finally realized, the continuous outward movement of the receiving opening 27 of the receiving hopper 26 is finally realized, the continuous accumulation of the deep-fried dough sticks 34 at the receiving opening 27 of the receiving hopper 26 is finally realized, the smoothness of receiving is ensured, the effective receiving capability of the receiving hopper 26 is improved, and the probability of scattering of the deep-fried dough sticks is reduced.

In the running process, a deep-fried dough stick is arranged between the conveying forks 17 of each conveying piece A, which is equivalent to the simultaneous frying of a plurality of deep-fried dough sticks, the deep-fried dough sticks are sequentially and successively connected, and the cooling and the oil draining are carried out firstly and finally enter the receiving hopper 26 along with the running conveying, so that the high efficiency of deep-fried dough sticks is realized.

The above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions; any alternative modifications or variations to the embodiments of the present invention will fall within the scope of the present invention for those skilled in the art.

The present invention is not described in detail in the present application, and is well known to those skilled in the art.
