Description

TECHNICAL FIELD

[0001] The present patent relates to an automatic pasta press. BACKGROUND

[0002] In the field of food processing, especially in the process of processing pasta products, the pasta press is an important equipment. The traditional pasta press usually only has a single pressing function, and needs manual feeding, conveying, pressing and folding operation, which is low in efficiency, high in labor intensity, and unstable in product quality. In addition, the existing pasta press generally has the following shortcomings:

[0003] 1. Uneven feeding, affecting the quality of the dough

[0004] The pasta press in the prior art often adopts manual feeding or simple gravity feeding method, which leads to the accumulation or blockage of the dough during feeding, and it is difficult to achieve uniform feeding. This uneven feeding method will lead to uneven thickness of the dough, affecting the effect of the subsequent pressing process, thereby reducing the quality of the finished product.

[0005] 2. Lack of stability in conveying process, easy to deviate

[0006] When the traditional pasta press conveys the dough, due to the lack of effective limiting device or adjustment mechanism of the conveying belt, the dough is easy to deviate or slip during transmission, affecting the pressing effect. Especially when the conveying belt is worn or the tension is inconsistent, this deviation phenomenon is more obvious.

[0007] 3. Inaccurate adjustment of pressing gap

[0008] Most of the existing pasta presses adopt manual adjustment of the gap between the pressing rollers, which is tedious and has low adjustment accuracy, and it is difficult to meet the needs of processing dough of different thicknesses. Once the adjustment is not in place, the dough is easy to have uneven thickness during pressing, resulting in poor quality of the finished product and affecting the user experience.

[0009] 4. Low efficiency of dough folding and lack of layering

[0010] In the traditional pasta pressing process, dough folding is usually completed by manual operation, which not only consumes a lot of manpower, but also easily affects the layering and toughness of the dough due to uneven folding. In addition, even some devices have automatic folding function, their structure design is often simple, and the folding effect is not ideal, resulting in poor quality and taste of the finished product.

[0011] In summary, the technical background section of the present patent aims to describe the current status of the prior art, and the deficiencies of the prior art indicate that the content of this section will provide the necessary background information for understanding the technical contributions and innovative points of the present patent. The signals disclosed in this background section only aim to increase the understanding of the overall background of the present patent, and should not be considered as implying subjective awareness in any form.

[0032] The present patent will be described in this embodiment below according to the drawings and some embodiments.

[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present patent will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] As Figs. 1-2As shown, the present patent provides an automatic dough pressing machine, mainly used for automatic feeding, conveying, pressing and folding of dough, improving the efficiency and quality of dough processing, specifically including a machine body, a feeding device, a conveying device, a pressing device, a dough folding mechanism and a microcontroller.

[0035] In this embodiment, the machine body adopts a shell with a frame structure, the top of which is provided with an opening for feeding raw materials, and the bottom is provided with a finished product discharge outlet. The machine body is internally installed with a feeding device, a conveying device, a pressing device and a dough folding mechanism. The finished product discharge outlet is located at the rear side of the dough folding mechanism and is connected to the folding mechanism through a guide plate to facilitate smooth discharge of the folded dough. The guide plate is arranged obliquely, with its upper end adjacent to the free end of the folding mechanism and its lower end communicating with the finished product discharge outlet, which can effectively guide the discharge of the dough.

[0036] In this embodiment, the feeding device includes a hopper, a screw pushing mechanism and a baffle. The hopper is fixed on the top of the machine body and is provided with an outlet at the bottom. The screw pushing mechanism is installed at the outlet and is composed of a horizontally arranged screw and a stepping motor driving the rotation of the screw. Through the precise control of the stepping motor, the rotation of the screw is realized, thereby uniformly pushing the dough in the hopper to the inlet of the conveying device. To avoid the dough from sliding down too fast, a baffle is provided above the outlet. The baffle can effectively control the flow speed of the dough, ensuring the stability of feeding.

[0037] In this embodiment, the conveying device includes two upper and lower conveying belts, a support frame, an adjusting screw and a limiting guide rail. The upper and lower conveying belts are driven by chain wheels and are fixed by corresponding upper and lower support frames.

[0038] In this embodiment, a clamping cavity is formed between the upper and lower conveying belts for clamping and conveying the dough. The width of the clamping cavity can be adjusted by the adjusting screw. One end of the adjusting screw is fixed to the support frame, and the other end is connected to a manual knob. Rotating the manual knob can drive the adjusting screw to rotate, thereby changing the position of the upper conveying belt relative to the lower conveying belt to adapt to the transmission requirements of dough of different thicknesses.

[0039] In this embodiment, the upper support frame is slidingly connected to the machine body through a vertical adjusting mechanism. The vertical adjusting mechanism includes a linear guide rail and an adjusting screw. The linear guide rail is arranged on the inner wall of the machine body in the vertical direction. The lower end of the adjusting screw is connected to the adjusting hole of the upper support frame through threads, and the upper end is connected to an adjusting knob. By rotating the adjusting knob, the upper support frame can be driven to slide along the linear guide rail, thereby realizing the precise adjustment of the height of the conveying belt.

[0040] In this embodiment, the limiting guide rail is arranged on both sides of the support frame to limit the lateral deviation of the conveying belt, ensuring the smooth running of the conveying belt during transmission and preventing deviation from affecting the processing effect of the dough.

[0041] In this embodiment, the pressing device is located behind the conveying device, including an upper pressing roller and a lower pressing roller, which are arranged in parallel and form a pressing gap between them for pressing the dough transported by the conveying belt.

[0042] In this embodiment, the upper pressing roller is connected to the machine body through a vertical guide rail and its lifting position is controlled by a hydraulic cylinder to adjust the pressing gap between the pressing rollers. The hydraulic cylinder is installed on the top of the machine body, and the height of the upper pressing roller can be accurately adjusted by controlling the extension and retraction of the piston rod of the hydraulic cylinder, so as to adapt to the pressing needs of doughs of different thicknesses.

[0043] In this embodiment, the surfaces of the upper and lower pressing rollers are provided with micro-convex textures to increase the friction between the dough and the pressing rollers, avoiding the dough from slipping during the pressing process. At the same time, the width of the pressing rollers is consistent with the width of the conveying belt to ensure the flatness and consistency of the dough during the pressing process.

[0044] In this embodiment, the dough folding mechanism is arranged behind the pressing device, including a horizontal folding plate, a folding roller, and a swing cylinder.

[0045] In this embodiment, the folding plate is hinged to the machine body through a rotating shaft, and the middle part of the folding plate is connected to the piston rod of the swing cylinder, which is fixed on the machine body. When the piston rod of the swing cylinder extends and retracts, it can drive the folding plate to swing up and down within a certain angle, realizing the automatic folding of the dough.

[0046] In this embodiment, the folding roller is fixed below the free end of the folding plate, and with the swinging of the folding plate, the folding roller can fold the dough, folding the pressed dough from the middle to both sides to form a multi-layer structure, thereby improving the toughness and layering of the dough.

[0047] Working principle of the feeding module

[0048] The feeding module is composed of a hopper, a screw pushing mechanism, and a blocking plate, which is responsible for uniformly conveying the dough from the hopper to the entrance of the conveying module.

[0049] Hopper:

[0050] The dough raw materials are put into the hopper through the opening at the top of the hopper. Due to the certain viscosity and plasticity of the dough, it cannot naturally slide to the outlet, so the screw pushing mechanism is set up for forced conveying.

[0051] Screw pushing mechanism:

[0052] The screw pushing mechanism is composed of a horizontally arranged screw and a stepping motor that drives the screw to rotate. The microcontroller controls the speed of the stepping motor, and the stepping motor drives the screw to rotate at a certain speed, thereby uniformly pushing the dough at the bottom of the hopper to the outlet. The thread design of the screw ensures that the dough can be continuously pushed, avoiding the accumulation or blockage.

[0053] Material blocking plate:

[0054] The material blocking plate is arranged above the outlet of the hopper, which plays a role in limiting the flow, preventing the dough from sliding too fast under the action of gravity, ensuring that the screw can uniformly transport the dough, and thus ensuring the stable operation of the conveying module.

[0055] Working principle of the conveying module

[0056] The conveying module mainly includes upper and lower conveying belts, support frames, adjusting screws, limiting guide rails, and vertical adjusting mechanisms, which are responsible for transmitting the dough output from the feeding module to the pressing module at an appropriate pressure and speed.

[0057] Clamping and transmission of the dough by the upper and lower conveying belts:

[0058] When the dough is pushed by the screw to the entrance of the conveying module, the upper and lower conveying belts run at the same speed, clamping and transmitting the dough to the pressing module. The synchronous operation of the conveying belts is controlled by the chain wheel transmission device, which is connected to the same power source, ensuring that the upper and lower conveying belts transmit synchronously, avoiding relative slipping or deviation of the dough during transmission.

[0059] Adjustment of the width of the clamping cavity:

[0060] A variable clamping cavity is formed between the upper and lower conveying belts, and the width of the clamping cavity can be adjusted by the adjusting screw. The adjusting screw is connected to the adjusting hole of the upper support frame, and by rotating the hand knob, the screw is rotated, thereby changing the position of the upper conveying belt and adjusting the width of the clamping cavity to adapt to the transmission requirements of dough of different thicknesses.

[0061] Function of the limiting guide rail:

[0062] The limiting guide rail is arranged along the two sides of the conveying belt to limit the lateral deviation of the conveying belt, ensuring that the conveying belt always runs within the preset track during conveying, avoiding uneven transmission or jamming of the dough due to the deviation of the conveying belt.

[0063] Working principle of the pressing module

[0064] The pressing module includes upper and lower pressing rollers, vertical guide rails, and hydraulic cylinders, which are responsible for pressing and forming the dough transmitted to this position.

[0065] Synchronous rotation of the pressing rollers and pressing:

[0066] The upper and lower pressing rollers are arranged in parallel and driven by the same power source, keeping synchronous rotation and clamping the dough sent by the conveying module. The surface of the pressing roller is provided with a micro-convex texture, which increases the friction between the dough and the pressing roller during pressing, ensuring that the dough moves uniformly with the pressing roller and avoiding slipping.

[0067] Adjustment of the pressing gap:

[0068] The upper roller is connected to the machine body through vertical guide rails and its lifting position is controlled by a hydraulic cylinder. The microcontroller controls the extension and retraction of the piston rod of the hydraulic cylinder according to the thickness of the dough or the processing requirements, thereby adjusting the pressing gap between the upper roller and the lower roller to obtain dough sheets of different thicknesses. This gap adjustment method has high precision and is suitable for various dough processing scenarios.

[0069] Matching the width of the rollers and the conveyor belt:

[0070] To ensure the flatness and consistency of the dough during pressing, the width of the upper roller and the lower roller is designed to match the width of the conveyor belt, thereby avoiding the occurrence of unpressed areas at the edges of the dough during pressing and ensuring the overall quality of the finished product.

[0071] Working principle of the dough folding module

[0072] The dough folding module, which is provided after the pressing module, includes a folding plate, a folding roller, and a swing cylinder, and is responsible for folding the pressed dough in multiple layers to improve the layering and toughness of the dough product.

[0073] Swing folding of the folding plate:

[0074] After the dough passes through the pressing module, it enters the folding module area, and the swing cylinder drives the folding plate to swing up and down at a specific frequency. When the folding plate rises, it folds the dough from the middle to both sides, forming a multi-layer structure. The folding plate is hinged to the machine body through a shaft, and the piston rod of the cylinder is connected to the middle of the folding plate. The action of the swing cylinder is controlled in real time by the microcontroller, ensuring the accuracy and stability of the folding operation.

[0075] Auxiliary role of the folding roller:

[0076] The folding roller is fixed below the free end of the folding plate. As the folding plate swings, the folding roller exerts pressure on the dough, further ensuring the folding effect and preventing the dough from slipping or unfolding during the folding process.

[0077] Guiding the finished product out by the guide plate:

[0078] The folded dough slides onto the guide plate under the action of gravity, and the guide plate is inclined to guide the dough to the finished product discharge outlet at the bottom of the machine. This ensures smooth discharge of the dough and prevents excessive sliding that can cause instability in the shape of the finished product.

[0079] The operation of the entire automatic dough press is controlled by the microcontroller, which is electrically connected to the feeding module, the conveying module, the pressing module, and the folding module. The microcontroller monitors and coordinates the operating status of each module in real time.

[0080] Automatic coordinated control:

[0081] After receiving the start signal, the microcontroller controls each module to start working in turn. First, it drives the stepper motor in the feeding module to rotate, pushing the dough to the conveying module. After the conveying module runs, it clamps and conveys the dough to the pressing module, which presses the dough according to the set pressing gap. Finally, the folding module starts to process the folded dough, and the finished product is discharged through the guide plate.

[0082] Step 1: Raw material feeding

[0083] 1. The user feeds the dough raw material into the hopper

[0084] The raw material is fed into the hopper through the opening at the top of the machine body, and the hopper is used to temporarily store the dough.

[0085] Step 2: Feeding

[0086] 1. The microcontroller starts the feeding module

[0087] The microcontroller controls the stepper motor to work, and the stepper motor drives the horizontal screw to rotate, pushing the dough at the bottom of the hopper uniformly to the conveying module.

[0088] 2. The baffle limits the sliding speed of the dough

[0089] When the screw pushes the dough, the baffle prevents the dough from sliding too fast due to gravity, ensuring that the screw can stably and uniformly convey the dough.

[0090] 3. The dough is pushed to the entrance of the conveying module

[0091] After being pushed by the screw, the dough enters the clamping cavity of the conveying module, preparing for the next transmission.

[0092] Step 3: Conveying

[0093] 1. The upper and lower conveying belts clamp the dough

[0094] The upper and lower conveying belts form a clamping cavity, and the synchronous operation of the conveying belts makes the dough clamped and transmitted to the pressing module at a stable speed.

[0095] 2. Adjust the width of the clamping cavity

[0096] If the thickness of the dough changes, the user can adjust the position of the upper conveying belt by rotating the adjustment knob to change the width of the clamping cavity, so that the dough is always clamped firmly and avoids deviation or loosening.

[0097] 3. The limit guide rail limits the deviation of the conveying belt

[0098] During the conveying process, the limiting guide rail effectively prevents the conveyor belt from lateral deviation, ensuring that the dough always remains on the correct transmission track.

[0099] Step 4: Pressing

[0100] 1. Microcontroller activates pressing module

[0101] The microcontroller controls the hydraulic cylinder action according to the preset parameters, and the hydraulic cylinder drives the upper press roller to rise and fall, adjusting the gap between the upper and lower press rollers to form a pressing gap suitable for the thickness of the dough.

[0102] 2. Synchronous rotation of upper and lower press rollers

[0103] Under the drive of the power device, the upper and lower press rollers rotate synchronously at the same speed, uniformly pressing the dough conveyed to the pressing module.

[0104] 3. Increase friction to prevent slipping

[0105] The micro-convex texture on the surface of the press roller increases the friction between the dough and the press roller during the pressing process, preventing the dough from slipping, thereby ensuring the stability and uniformity of the pressing process.

[0106] 4. Pressed dough is output to the folding module

[0107] After pressing is completed, the dough is continuously conveyed to the subsequent folding module.

[0108] Step 5: Folding

[0109] 1. Microcontroller activates folding module

[0110] The microcontroller controls the swing cylinder action, and the cylinder piston rod drives the folding plate to swing up and down within a certain angle.

[0111] 2. Folding plate folds dough to both sides

[0112] When the pressed dough enters the folding module area, the folding plate rises and folds the dough from the middle to both sides, forming a multi-layer structure.

[0113] 3. Folding roller assists folding and shaping

[0114] The folding roller is fixed below the free end of the folding plate, and when the folding plate swings, it applies a certain pressure to the dough to ensure that the dough is folded and shaped and remains stable.

[0115] 4. Folded dough slides onto guide plate

[0116] The folded dough slides onto the guide plate under the action of gravity. The guide plate is inclinedly arranged to smoothly guide the dough to the finished product discharge outlet.

[0117] Step 6: Finished product discharge

[0118] 1. The folded dough slides along the guide plate to the finished product discharge outlet

[0119] The upper end of the guide plate is adjacent to the folding mechanism, and the lower end is communicated with the finished product discharge outlet. The folded dough slides along the guide plate and is finally discharged from the finished product discharge outlet at the bottom of the machine body.

[0120] 2. Complete the entire processing flow

[0121] The dough completes the continuous processing from feeding, conveying, pressing to folding in the automatic dough pressing machine, and finally obtains the finished product sheet with a multi-layer structure.
