Technical Field
The invention belongs to the technical field of kitchen equipment, relates to a cake rolling machine, and particularly relates to a rotary semi-automatic cake rolling machine driven by a one-way bearing.
Background
At present, in cake rolling machines in the market, dough blanks are mostly placed between two circular discs, a hydraulic cylinder is used for rapidly extruding the dough blanks with strength, the dough blanks are rapidly extended outwards under the action of a large extruding force, the dough blanks are formed into cakes in one step, the working speed is high, manpower is not needed, the taste is poor, and the cakes made by manual rolling have no sense of strength.
Traditional manual rolling is that the rolling pin is used for rolling, then the rolling pin is rotated by an angle of about 30-60 degrees and is rolled once again, the repeated rotation angle and the repeated rolling are realized, the dough blank is gradually extended into the pancake, the working speed is slow, the labor capacity is large, but the taste is good, the dough is chewy and chewy, and a lot of consumers still like eating the manual rolling of the pancake. Rolling a pancake is also a skill, and a large amount of practice and practice are needed for a long time to make a pancake with uniform thickness and a perfect round appearance.
The flour contains protein and starch, the wheat protein absorbs water and swells after being mixed with water to form dough, protein molecules are contacted with each other, chemical bonds among different protein molecules are crosslinked with each other to form a huge three-dimensional net structure, other components such as starch, fat, low molecular sugar, inorganic salt and the like are filled in a gluten net structure to form dough with good viscoelasticity and ductility, the chemical bonds among the protein molecules are gradually stretched in the manual rolling process and are not easy to break, or a part of the protein molecules are broken and can be recombined, fibrous components exist in the prepared dough, so the baked dough is chewy; the chemical bond can be rapidly broken in the one-step forming process, and the prepared cake lacks fibrous components, so that the cake has no sense of strength.

The working process of the present invention is as follows.
1) And making the kneaded dough into an oblate blank, and placing the oblate blank in the middle of the upper surface of the turntable and right below a crack between the left compression roller and the right compression roller. Care was taken to ensure that the dough pieces were wetted with sufficient dry flour.
2) Hand the rocker handle and push forward, then the middle part extrusion of rocker handle rolls pressure control rod end gyro wheel, roll pressure control rod end gyro wheel and roll pressure control earrings and roll pressure control cylinder piston rod translation forward on one side the roll, the transmission liquid of rolling the no pole intracavity of pressure control pneumatic cylinder receives the extrusion, in the same direction as the no pole intracavity of pipeline inflow pressure cylinder, the piston of rolling the pneumatic cylinder overcomes the pressure promotion of rolling the pressure cylinder pressure spring and rolls pressure hydraulic piston rod translation downwards, the drive is rolled the subassembly and is translated downwards.
3) Left side compression roller and right compression roller are translation down together, press on the dough blank simultaneously, left side compression roller and right compression roller receive ascending resistance simultaneously, left side compression roller receives the elastic tension who overcomes the compression roller elastic sleeve of resistance and swings left-hand upward around left compression roller hinge, right side compression roller receives the elastic tension who overcomes the compression roller elastic sleeve of resistance and swings right-hand upward around right compression roller hinge, left side compression roller and right compression roller are to the extruded simultaneous distance grow of dough blank, roll on the dough blank, play the roll pressure effect to the dough blank, roll the left and right edges of pressing the dough blank respectively until left side compression roller and right compression roller.
4) Relax the rocker handle, then roll the automatic translation that makes progress of pressure hydraulic piston rod under the pressure effect of rolling the pressure cylinder pressure spring, roll the translation that makes progress of pressure subassembly, under the elastic tension effect of compression roller elastic sleeve, left side compression roller and right compression roller are close to each other on one side the roll extrusion on the dough blank, until leaning on together, then upward translation leaves the dough blank. Due to the limiting effect of the lower limiting table of the left compression roller and the lower limiting table of the right compression roller, the left compression roller and the right compression roller automatically return to the central position and lean against each other. The transmission fluid in the rodless cavity of the rolling hydraulic cylinder is extruded to flow into the rodless cavity of the rolling control hydraulic cylinder through a pipeline, a piston rod of the rolling control cylinder is driven to extend backwards to the tail end of a stroke, a rocker is just pushed to be in a vertical state, and the rocker is close to a roller at the end of the driving control rod but does not apply force. The forward pushing amplitude of the rocker handle is large, the distance between the left compression roller and the right compression roller is large, otherwise, the pushing amplitude is small, and the separation distance is small.
5) The handle of the rocker is held to push backwards, the middle part of the rocker extrudes the rod end roller of the drive control rod, the rod end roller of the drive control rod rolls and drives the drive control lug ring and the piston rod of the drive control cylinder to translate backwards, the transmission liquid in the rodless cavity of the drive control hydraulic cylinder is extruded and flows into the rodless cavity of the drive hydraulic cylinder along a pipeline, the piston of the drive hydraulic cylinder overcomes the pressure of the pressure spring of the drive cylinder to push the piston rod of the drive hydraulic cylinder to translate backwards, and the drive assembly is pushed to translate backwards.
And when the left one-way bearing is observed in a plan view, the outer ring of the left one-way bearing is locked and can not rotate around the anticlockwise direction relative to the inner ring, the left swing arm overcomes the elastic tension of the elastic sleeve of the left swing arm to push the left one-way bearing, the outer ring of the left one-way bearing pushes the turntable to rotate along the anticlockwise direction by means of friction force, and the outer ring of the left one-way bearing is locked and can not rotate relative to the inner ring. The outer ring of the right one-way bearing freely rotates clockwise relative to the inner ring, the right swing arm overcomes the elastic tension of the right swing arm elastic sleeve to push the right one-way bearing, and the outer ring of the right one-way bearing rotates clockwise under the driving of the turntable.
When the rocker handle is loosened, the pressure spring of the driving cylinder pushes the piston of the driving hydraulic cylinder to automatically reset, the driving hydraulic piston rod pulls the driving assembly to move forwards, the outer ring of the right one-way bearing is locked and can not rotate around the anticlockwise direction relative to the inner ring, the right one-way bearing is always close to the rotary table under the action of the elastic tension of the elastic sleeve of the right swing arm, and the rotary table is stirred to rotate anticlockwise through friction. The outer ring of the left one-way bearing freely rotates around the clockwise direction relative to the inner ring, the left one-way bearing always abuts against the turntable under the action of elastic tension of the elastic sleeve of the left swing arm, and the outer ring of the left one-way bearing rotates clockwise under the driving of the turntable.
The transmission fluid in the rodless cavity of the driving hydraulic cylinder flows into the rodless cavity of the driving control hydraulic cylinder through a pipeline, the piston rod of the driving control cylinder and the driving control lug ring are pushed to translate forwards until the tail end of the stroke, and the rocker is pushed to a vertical position.
In this way, the turntable is urged by the drive assembly to rotate through an angle of about 30 to 60 degrees, the dough mass above follows through the same angle, and the rocker is urged rearwardly through a greater angle of rotation than the turntable, and vice versa through a lesser angle of rotation.
And (3) repeating the steps 2) to 5) for multiple times, repeating a series of actions of descending the compression roller- > reciprocating rolling-pressing- > ascending the compression roller- > driving the turntable to rotate- > ascending the compression roller for multiple times, and gradually extending the dough blank outwards from a thicker oblate shape, so that the diameter of the dough blank is increased, the thickness of the dough blank is smaller, and the dough blank is finally changed into a thin pancake.
It should be noted that a small protrusion is often generated in the middle of the dough cake due to the fact that the position between the two pressing rollers cannot be pressed, when the pressing is nearly finished, the dough cake is pushed by hand, the protrusion deviates from the position in the middle of the rotary table, the dough cake is translated to the position where the pressing rollers can press, and the small protrusion is pressed and flattened for several times.
The invention has the beneficial effects that: the rolling machine simulates manual rolling for repeatedly changing angles, is high in efficiency, saves labor, and makes the flour cake good in taste, chewy, uniform in thickness and round in appearance.

3) The left pressing roller 1332 and the right pressing roller 1342 move downwards together and press on the dough blank, the left pressing roller 1332 and the right pressing roller 1342 simultaneously bear upward resistance, the left pressing roller 1332 overcomes the elastic tension of the pressing roller elastic sleeve 135 by resistance and swings upwards leftwards around the left pressing roller hinge 1335, the right pressing roller 1342 overcomes the elastic tension of the pressing roller elastic sleeve 135 by resistance and swings upwards rightwards around the right pressing roller hinge 1345, the distance between the left pressing roller 1332 and the right pressing roller 1342 when the dough blank is extruded is increased, the dough blank rolls on the dough blank and plays a role in rolling the dough blank until the left pressing roller 1332 and the right pressing roller 1342 respectively roll to the left edge and the right edge of the dough blank.
4) When the rocker handle 222 is released, the rolling hydraulic piston rod 144 automatically moves upwards in a horizontal moving manner under the pressure action of the rolling cylinder compression spring 142, the rolling component 13 moves upwards in a horizontal moving manner, and under the action of the elastic tension of the compression roller elastic sleeve 135, the left compression roller 1332 and the right compression roller 1342 approach each other while rolling on the dough blank until the dough blank approaches to each other, and then move upwards to leave the dough blank. Due to the limiting effect of the left roller lower limiting table 1333 and the right roller lower limiting table 1343, the left roller 1332 and the right roller 1342 automatically return to the center position and lean together. The transmission fluid in the rodless cavity of the rolling hydraulic cylinder 14 is extruded to flow into the rodless cavity of the rolling control hydraulic cylinder 24 through a pipeline, the piston rod 242 of the rolling control cylinder is driven to extend backwards to the tail end of the stroke, the rocker handle 222 is just pushed to be in a vertical state, and the rocker handle 222 is close to the roller 251 of the drive control rod end and does not apply force. The rocker handle 222 pushes forward a greater distance, and the left pressure roller 1332 and the right pressure roller 1342 are separated by a greater distance, whereas the pushing amplitude is smaller and the separation distance is smaller.
5) When the rocker handle 222 is held by hand and pushed backward, the middle part of the rocker handle 222 extrudes the drive control rod end roller 251, the drive control rod end roller 251 rolls and drives the drive control earring 252 and the drive control cylinder piston rod 262 to translate backward, the transmission fluid in the rodless cavity of the drive control hydraulic cylinder 26 is extruded and flows into the rodless cavity of the drive hydraulic cylinder 16 along the pipeline, the piston of the drive hydraulic cylinder 16 overcomes the pressure of the drive cylinder pressure spring 162 to push the drive hydraulic piston rod 164 to translate backward, the drive assembly 15 is pushed to translate backward, and the direction of translation of the swing arm support 152 is shown as the direction C in fig. 11.
When viewed from above, the outer ring of the left one-way bearing 157 is locked and cannot rotate with respect to the inner ring in the counterclockwise direction, the left swing arm 155 pushes the left one-way bearing 157 against the elastic pulling force of the left swing arm elastic sleeve 159, and the outer ring of the left one-way bearing 157 pushes the turntable 12 to rotate in the counterclockwise direction by the friction force, as shown in the direction G in fig. 11, the outer ring of the left one-way bearing 157 is locked and cannot rotate with respect to the inner ring. The outer ring of the right one-way bearing 156 is free to rotate clockwise relative to the inner ring, the right swing arm 154 overcomes the elastic pulling force of the right swing arm elastic sleeve 158 to push the right one-way bearing 156, and the outer ring of the right one-way bearing 156 is driven by the turntable 12 to rotate clockwise.
When the rocker handle 222 is released, the driving cylinder pressure spring 162 pushes the piston of the driving hydraulic cylinder 16 to automatically reset, the driving hydraulic piston rod 164 pulls the driving assembly 15 to move forwards, as shown in a direction D in fig. 12, the outer ring of the right one-way bearing 156 is locked and can not rotate around the counterclockwise direction relative to the inner ring, the right one-way bearing 156 always abuts against the turntable 12 under the elastic tension of the right swing arm elastic sleeve 158, and the turntable 12 is pulled to rotate counterclockwise through friction, as shown in a direction G in fig. 12. The outer ring of the left one-way bearing 157 freely rotates clockwise relative to the inner ring, the left one-way bearing 157 always abuts against the turntable 12 under the elastic tension of the left swing arm elastic sleeve 159, and the outer ring of the left one-way bearing 157 rotates clockwise under the driving of the turntable 12.
The transmission fluid in the rodless cavity of drive cylinder 16 flows into the rodless cavity of drive control cylinder 26 through a pipeline, and pushes drive control cylinder piston rod 262 and drive control lug 252 to translate forward until the end of the stroke, pushing rocker handle 222 to the vertical position.
In this way, the turntable 12 is rotated through an angle of about 30 to 60 degrees by the drive assembly 15, the dough mass above follows through the same angle, and the rocker handle 222 is pushed backwards to a greater extent, so that the turntable 12 is rotated through a greater angle, and vice versa.
And (3) repeating the steps 2) to 5) for multiple times, repeating a series of actions of descending the compression roller- > reciprocating rolling-pressing- > ascending the compression roller- > driving the turntable to rotate- > ascending the compression roller for multiple times, and gradually extending the dough blank outwards from a thicker oblate shape, so that the diameter of the dough blank is increased, the thickness of the dough blank is smaller, and the dough blank is finally changed into a thin pancake.
It should be noted that a small protrusion is often generated in the middle of the dough cake due to the fact that the position between the two pressing rollers cannot be pressed, when the pressing is nearly finished, the dough cake is pushed by hand, the protrusion deviates from the position in the middle of the rotary table 12, the dough cake is translated to the position where the pressing rollers can press, and the small protrusion is pressed and flattened for several times.
The beneficial effects of this embodiment: the rolling machine simulates manual rolling for repeatedly changing angles, is high in efficiency, saves labor, and makes the flour cake good in taste, chewy, uniform in thickness and round in appearance.
