[0041] The stick pressing spring 11 is made of stainless steel precision belt stamping and has elasticity. When the rotating shell 4 is opened, the stick pressing spring is in a free state. During the process of closing the rotating shell 4, the stick pressing spring is pressed on the stick magazine 7 in advance and is in a compressed state with the continuous closing, and is used for preventing the stick from scattering when the rotating shell 4 is in the vertical state.

[0042] Preferably, in any of the above solutions, the stick feeding mechanism comprises an electric push rod 12 fixedly installed on the bottom of the rotating shell 4, the electric push rod 12 is in a horizontal state when the rotating shell 4 is in the vertical working state, a feeding push fork 13 is connected to the rear end of the telescopic end of the electric push rod 12, the front end of each push material stainless steel column 14 on the front side of the feeding push fork 13 is movably inserted through a guide hole in the corresponding position of the lower part of the rear side wall of the rotating shell 4 and extends to the inside of the guide hole, the front end of each push material stainless steel column 14 is in abutment with the rear side of the lowermost frozen stick 8 in the stacked state through a through channel 15 in the stick magazine 7, and each push material stainless steel column 14 is used for pushing the corresponding frozen stick 8 to the front side and pushing it out to the stick receiving and transferring mechanism 16 of the matched stick frying equipment in front of the fixed shell 1 in the state of the electric push rod 12.

[0043] The electric push rod 12 in the fried dough stick feeding mechanism is fixed on the rotating shell 4, the electric push rod 12 is connected with the feeding push fork 13, one end of the feeding push fork 13 is composed of a plurality of pushing material stainless steel columns 14, the movement direction of the pushing material stainless steel columns 14 is constrained by the linear bearing, so that the pushing material stainless steel columns 14 can only make reciprocating linear motion, so that the frozen fried dough stick 8 can be pushed out of the feeding channel 29 to the space between the upper material guiding directional guide rail 17 and the lower material guiding directional guide rail 18.

[0045] The upper material guiding directional guide rail 17 and the lower material guiding directional guide rail 18 cooperatively form a channel for the frozen fried dough stick 8 to move outward, the frozen fried dough stick 8 is moved to the vertical material blocking part 19, then falls downwardly in the material falling channel 20 and falls on the corresponding conveying fork 27, and finally is sent to the frying cavity for frying by the continuous operation of the conveying fork 27.

[0049] Embodiment 2: Compared with embodiment 1, the embodiment also comprises:

[0050] The oil stick receiving and transferring mechanism 16 comprises a chain wheel driving shaft 22 rotating horizontally from top to bottom, a chain wheel driven shaft 23, a driving chain wheel 24 and a driven chain wheel 25 fixedly installed on the outer side wall of the chain wheel driving shaft 22 and the chain wheel driven shaft 23, the number of the driving chain wheel 24 and the driven chain wheel 25 is two, and each driving chain wheel 24 is connected with the driven chain wheel 25 below it through a transferring chain 26; the driven chain wheel 25 is located inside the frying cavity below the oil surface of the existing oil stick frying equipment, and the driving chain wheel 24 is located above the oil surface, a plurality of conveying prongs 27 are uniformly and spaced apart along the circumference of the transferring chain 26, an inductive switch is arranged at the bottom of each conveying prong 27, each inductive switch is connected with the controller of the oil stick frying equipment, and each conveying prong 27 is fixedly installed on the transferring chain 26 at the corresponding position, when the chain wheel driving shaft 22 rotates, the transferring chain 26 and each conveying prong 27 are driven to rotate, the conveying prong 27 close to the side of the fixed shell 1 is used for receiving each frozen oil stick 8 sent by the feeding channel 20, and the inductive switch is used for inductive positioning when the frozen oil stick 8 is received, and the time is prolonged after the inductive positioning is completed to prevent the frozen oil stick 8 at the current position from being placed on the corresponding conveying prong 27. Under the action of the conveying prong 27, the frozen oil stick 8 enters the frying cavity of the oil stick frying equipment and is pressed by the upper adjacent conveying prong 27 to prevent it from floating up, so that the immersion frying operation is ensured, and the effect and uniformity of the oil stick frying are improved.

[0051] The oil stick receiving and transferring mechanism 16 designed in the application is used in cooperation with the current oil stick feeding mechanism, and when the oil stick feeding mechanism pushes out the frozen oil stick 8, the frozen oil stick 8 directly falls on the corresponding conveying prong 27, at this time, the inductive switch at the bottom of the conveying prong 27 above the current conveying prong is used for detecting that the feeding at the current position below is in place, and then the receiving action is performed and the time is prolonged to complete the receiving action.

[0052] In any of the above schemes, it is preferred that the gap between the oil stick box 7 and the inner side wall of the rotating shell 4 is filled with thermal insulation material, and the gap around the refrigeration evaporation plate 9 is filled with thermal insulation material.

[0053] Specific working principle:

[0054] When the system is used alone, the time can be set by a matched controller to control the electric push rod 12 to pull back, that is, the feeding push fork 13 pushes out the frozen oil stick 8, the frozen oil stick 8 at the top point falls from the feeding channel 20 and falls into the frying pot; then the electric push rod 12 is reset, the frozen oil stick 8 in the oil stick box 7 falls to the bottom under the action of gravity, and the reciprocating is alternated.

[0055] The controller counts the number of frozen sticks 8, and the push rod reciprocates one cycle, and the number of sticks is reduced by 1. When the number of sticks is 0, the audible and visual alarm starts to alarm, and the mechanism stops running. When the rotating shell 4 is opened, the feeding bin opening and closing proximity switch 21 senses a disconnection signal. When the frozen sticks 8 are loaded and the rotating shell 4 is closed, the feeding bin opening and closing proximity switch 21 senses a connection signal, so that the mechanism continues to run the next cycle.

[0056] When the system is used with the stick receiving and transferring mechanism 16, a conveying fork 27 sensing switch needs to be arranged on one side of the conveying fork 27. When a conveying fork 27 is running downward and is sensed by the conveying fork 27 sensing switch, the controller receives a signal and delays for a period of time.

[0057] The conveying fork 27 continues to descend, and the delayed electric push rod 12 also starts to push the stick. When the stick is pushed to the top, the conveying fork 27 just descends to the lower end of the stick, and the stick falls from the falling channel 20 of the upper and lower material guiding directional guide rails 17 and 18 under the action of gravity and falls onto the conveying fork 27, and then descends with the fork into the oil surface of the frying chamber to start frying; when the frozen stick 8 is pushed to the end, the vertical material blocking part 19 also functions to position and prevent the frozen stick 8 from turning over. As long as the placement direction of the frozen stick 8 in the stick box 7 is controlled, it can be ensured that the direction of the joint of the frozen stick 8 is vertical when it falls, and it will not turn over and be squeezed in the oil when it enters the oil for frying, so that the forming effect is good, the consistency is high, and the probability of oil splashing is reduced.

[0058] When the stick is pushed to the top, the controller controls the electric push rod 12 to immediately return to the original position, ready to receive the sensing signal of the next conveying fork 27, and reciprocate alternately. The controller counts the number of sticks, and the push rod reciprocates one cycle, and the number of sticks is reduced by 1. When the number of sticks is 0, the audible and visual alarm starts to alarm, and the mechanism stops running. When the rotating shell 4 is opened, the feeding bin opening and closing proximity switch 21 senses a disconnection signal. When the frozen sticks 8 are loaded and the rotating shell 4 is closed, the feeding bin opening and closing proximity switch 21 senses a connection signal. Thus, the mechanism continues to run the next cycle.

[0059] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application; any alternative improvement or change made by those skilled in the art to the embodiments of the present application falls within the protection scope of the present application.
