The extrusion roller applies shear force through its rotation, and the patting component breaks and restructures the dough structure through vertical impact force, simulating the folding-stretching-slapping action of hand kneading. Combined with the spacing design of the extrusion roller and the kneading cylinder, the efficiency of mechanical transmission is optimized.
It improves the kneading effect of the dough, ensures uniform gluten development and extensibility, and is suitable for the production needs of specific doughs such as twisted dough sticks and peach shortbread. It also reduces ineffective friction and lowers the labor intensity of workers.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pastry processing equipment, and in particular to a dough kneading mechanism of a dough kneading machine. Background Technology
[0002] Twisted dough sticks with peach blossom filling are a snack that combines the characteristics of twisted dough sticks and peach blossom filling. After kneading the dough, it is made into peach blossom filling dough, and then a twisted dough stick is placed on the peach blossom filling dough before baking. Twisted dough sticks with peach blossom filling require the raw materials to be made through a dough kneading machine. The dough kneading machine is an auxiliary equipment for pasta processing. It operates smoothly, with low noise and strong kneading force. The kneaded dough has good elasticity and high gluten strength. The parts in contact with the materials are made of stainless steel, which is rust-proof, durable, clean and hygienic. It is an essential piece of equipment for the pasta processing industry and the catering industry. This machine is suitable for pasta processing, pastry, and bread food industries. It kneads and presses various shortbread and tough doughs. Simply place the dough on the conveyor belt, and after starting the machine, it will automatically convey, knead, press and fold, reducing the number of times the hands come into contact with the machine. There is no need for manual feeding of dough, eliminating safety hazards and reducing the labor intensity of workers.
[0003] Twisted dough sticks and peach crisps are foods made from twisted dough sticks and peach crisps. They need to be kneaded in a dough mixer before further processing. Existing dough mixers mainly knead dough by squeezing, folding and stretching, which does not produce good results. Utility Model Content

[0013] This utility model provides a dough kneading mechanism for a dough kneading machine, which integrates an extrusion roller and a patting component on the same revolution system (rotating frame). The extrusion roller applies continuous shear force to the dough through its rotation, promoting the formation of the gluten network; the patting component breaks down and reassembles the original structure of the dough through vertical impact force. The two components alternately act on different parts of the dough during revolution, simulating the "folding-stretching-slapping" compound action of hand kneading. This effectively solves the problems of uneven gluten strength and insufficient extensibility caused by traditional dough kneading machines relying solely on extrusion. It is especially suitable for the high gluten strength and crispness balance required for twisted dough sticks and peach crisps. Furthermore, the spacing design between the outer side of the extrusion roller and the inner wall of the kneading cylinder ensures that the dough fully contacts the mechanical parts while reserving space for extension. The design of the inner roller surface fitting the axis of the kneading cylinder further optimizes the mechanical transmission efficiency and reduces ineffective friction, thereby improving the kneading effect of the dough kneading machine.

[0019] This application discloses a dough kneading mechanism for a dough kneading machine. (Refer to...)

A mounting bracket is connected to the fixed frame 3, and the rotating motor 56 is connected to the mounting bracket. The drive pulley 53 is connected to the end of the rotating motor 56 through which the output shaft passes. The track 55 is tensioned and wound between the drive pulley 53 and the driven pulley 54.
[0024] A slider 42 is connected to the rotating frame 4, and a guide rail 31 is connected to the bottom of the fixed frame 3. The guide rail 31 is arranged in a ring shape, and the slider 42 is slidably mounted on the guide rail 31.
[0025] The tapping assembly 6 includes a push cylinder 61, a tapping block 62, a guide rod 63, and a linear bearing 64. The push cylinder 61 is connected to the rotating frame 4. The tapping block 62 is connected to the end of the piston rod of the push cylinder 61 that passes through the rotating frame 4.

[0027] Both the drive motor 73 and the push cylinder 61 can be fitted with protective covers.
[0028] The implementation principle of the kneading mechanism of a dough kneading machine according to an embodiment of this application is as follows: During operation, several dough balls are placed in the kneading drum 2 and evenly distributed between the outer roller surface of the extrusion roller 41 and the inner wall of the kneading drum 2. Then, the drive motor 73 and the push cylinder 61 are started, causing the extrusion roller 41 to rotate and the patting block 62 to pat up and down at a uniform speed. After that, the rotation motor 56 is started to drive the drive pulley 53 to rotate. Through the joint cooperation of the drive pulley 53, the driven pulley 54 and the track 55, the rotating shaft 52 is driven to rotate. The rotating shaft 52 drives the rotating frame 4 to rotate, so that the extrusion roller 41 and the patting plate alternately act on different parts of the dough during the revolution, simulating the "folding-stretching-slapping" compound action of hand kneading, wherein the rotation direction of the extrusion roller 41 and the rotating frame 4 is opposite.
