[0019] The technical solution of the utility model is further described below in conjunction with embodiments.

[0020] Example 1: Figure 1-4 As shown, a dough kneading machine comprises a working platform 1 and a conveyor belt 2, wherein the conveyor belt passes through the working platform from left to right, and the upper part of the conveyor belt is attached to the upper surface of the working platform, and at least four telescopic cylinders are installed on the working platform, including a first telescopic cylinder 3, a second telescopic cylinder 4, a third telescopic cylinder 5 and a fourth telescopic cylinder 6, wherein the first telescopic cylinder and the second telescopic cylinder are located at the front side of the conveyor belt, and the third telescopic cylinder and the fourth telescopic cylinder are located at the rear side of the conveyor belt, and the piston shaft of each telescopic cylinder faces upward, and the upper end of the piston shaft is against and fixedly installed with an upper platform 7;

[0021] A motor 8 and a reducer 9 are installed on the upper platform, the motor and the reducer are connected, the output shaft 10 of the reducer passes downward through the upper platform, and a crank 11 is installed at the end of the output shaft, and a rubbing board 12 is installed at the lower end of the crank, and the lower surface of the rubbing board faces the conveyor belt;

[0022] A plc controller is also provided, which is connected with the conveyor belt and the telescopic cylinder, and controls the operation of the conveyor belt and the extension and retraction of the telescopic cylinder.

[0023] In this embodiment, the output shaft of the reducer and the crank handle may be connected by a coupling, or may be integrally connected, as long as the output shaft of the reducer can rotate with the crank handle.

[0024] Operation method: The utility model is used as follows: put the dough on the starting end of the conveyor belt, turn on the PLC controller and the motor; the PLC controller controls the telescopic cylinder to do telescopic movement, driving the upper platform to move up and down, so that the kneading plate moves up and down; the PLC controller also controls the conveyor belt to transport the dough; after the motor is turned on, the output shaft of the reducer rotates, the output shaft of the reducer rotates the crank, and the rotation of the crank drives the kneading plate to rotate in circles;

[0025] Through the setting of the PLC controller, when the dough is transported to the lower side of the kneading plate, the cylinder contracts and brings the kneading plate downward to knead the dough; when the dough leaves the lower side of the kneading plate, the cylinder extends and brings the kneading plate upward to end kneading the dough.

[0026] Embodiment 2:

[0027] A further improvement to Example 1 is that the controller causes each telescopic cylinder to perform a periodic action of extending-retracting-extending-retracting-extending-…, and the controller also causes the conveyor belt to perform a periodic action of running-stopping-running-stopping-running…, and the dough is placed in batches at the starting section of the conveyor belt in the shape of Figure 5 As shown, when a batch of dough is transported to the bottom of the kneading plate, the conveyor belt stops, the telescopic cylinder is retracted, and the kneading plate kneads the dough downwards. After kneading for several seconds, the telescopic cylinder is extended, and the kneading plate moves upwards away from the dough. The conveyor belt runs, and the kneaded dough leaves the kneading station, until the next batch of dough is transported to the bottom of the kneading plate, the conveyor belt stops, the telescopic cylinder is retracted, and the kneading plate moves downwards to knead the dough..., and this action is repeated.

[0028] In this way, the dough is kneaded automatically. In this embodiment, the dough needs to be placed in batches, and the dough is placed on the conveyor belt in the shape of Figure 5 shown.

[0029] In this way, the kneading time can be adjusted through PLC, the kneading time can be long or short, the texture of the kneaded dough is more uniform, and it can be freely adjusted according to actual needs, which is more convenient to use.

[0030] Embodiment 3:

[0031] Based on Example 2, the running cycle of the conveyor belt is 17s and the stopping cycle is 6s.

[0032] The stop cycle is 6s, that is, the kneading time for the dough is 6s, which meets the actual needs.

[0033] Embodiment 4:

[0034] On the basis of embodiments 1, 2 and 3, four follower handles 13 are further installed on the upper platform. The four follower handles are installed at the four corners of the upper platform, and the lower ends of the four follower handles are connected to the four corners of the kneading board.

[0035] The follower crank can rotate along with the rotation of the active crank, so that the kneading board can be more stable during operation, the frame volume can be reduced, and shaking can be prevented.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
