Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a piston-type dough quantitative dividing machine. Background Technology

[0002] In the field of pasta processing, quantitative dough division is a crucial step in ensuring standardized product production. However, existing dough division equipment faces numerous problems in practical applications. Regarding the dough feeding method, most mainstream equipment on the market currently employs a auger-type feeding structure. The auger feeds the dough by rotating and pushing it. During this process, the continuous friction and compression between the auger blades and the dough causes mechanical damage to the internal gluten, disrupting its integrity. As gluten is a core factor affecting the texture of pasta, damage to it results in a final product that is hard, lacks elasticity, or is easily broken, severely impacting product quality. This is particularly problematic for products like steamed buns, dumplings, and noodles, which require high-quality textures. Utility Model Content

[0003] The purpose of this invention is to provide a piston-type dough quantitative divider, which solves the problems of existing dough dividing equipment that use a auger-type dough feeder, which easily damages the integrity of the gluten, has a large equipment size and occupies a lot of space, and has poor consistency in the weight of the cut dough.

[0009] A fixed plate is vertically fixedly installed on the side wall of the support frame. The side wall of the fixed plate is provided with a cutting mechanism. The execution end of the cutting mechanism can cooperate with the discharge end of the dough bucket to quantitatively cut the dough extruded and output by the dough bucket.

[0010] Preferably, the noodle feeding device includes a second motor and a lead screw. The second motor is fixedly mounted on the top of the inner wall of the connecting box via a motor mount. The output end of the second motor is connected to a worm gear lifter. The lead screw passes through the worm gear lifter in the vertical direction, and the worm gear lifter can drive the lead screw to reciprocate in the vertical direction. A pressure plate is fixedly mounted on the bottom end of the lead screw via a flange. The outer diameter of the pressure plate is adapted to the inner diameter of the noodle bucket.

[0011] Preferably, the pressure plate is made of food-grade stainless steel, and a metal probe is fixedly installed at the bottom of the connecting box and on one side of the lead screw. The metal probe is used to detect the lifting position of the pressure plate to provide feedback for adjusting the amount of dough supplied.

[0012] Preferably, a discharge pipe is vertically connected to the bottom center of the dough bucket, and a clamp is fitted on the outer circumference of the discharge end of the discharge pipe.

The top of the adjusting bolt is rotatably connected to the fixed plate. A first infrared sensing probe is fixedly installed on the surface of the connecting plate. The first infrared sensing probe is used to monitor the length of the dough extruded from the discharge pipe to provide feedback for controlling the cutting timing.

[0015] Preferably, a second infrared sensor is fixedly installed on the surface of the fixed plate and on one side of the turntable. The second infrared sensor is used to monitor the rotation angle of the turntable to provide feedback control on the start and stop status of the first motor.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Reference Figure 1-5 A piston-type dough quantitative dividing machine, comprising:

[0029] A support frame, the top of which is fixedly fitted with a connecting box;

[0030] The dough bucket, which is detachably mounted on top of the support frame and located directly below the connecting box, is used to hold the dough to be divided.

[0031] The dough feeding device is fixedly installed inside the connecting box, and its execution end extends vertically downward into the inside of the dough bucket to apply vertical downward extrusion force to the dough inside the bucket.

[0032] A fixed plate is vertically fixedly installed on the side wall of the support frame. The side wall of the fixed plate is provided with a cutting mechanism. The execution end of the cutting mechanism can cooperate with the discharge end of the dough bucket to quantitatively cut the dough extruded and output by the dough bucket.

[0033] The support frame serves as the foundation for the entire equipment, the connecting box provides installation space for the dough feeding device, the dough bucket is used to hold the dough and has a detachable design for easy loading and cleaning, the dough feeding device outputs the dough through extrusion, and the cutting mechanism works together to complete quantitative division. All components work together to form a complete dough division process.

[0034] Furthermore, the noodle feeding device includes a second motor and a lead screw. The second motor is fixedly mounted on the top of the inner wall of the connecting box via a motor mount. The output end of the second motor is connected to a worm gear lifter. The lead screw passes through the worm gear lifter in the vertical direction, and the worm gear lifter can drive the lead screw to reciprocate in the vertical direction. A pressure plate is fixedly mounted on the bottom end of the lead screw via a flange. The outer diameter of the pressure plate is adapted to the inner diameter of the noodle bucket.

[0035] The second motor provides power, and the worm gear lifter converts the motor's rotational motion into the vertical motion of the lead screw, which in turn drives the pressure plate to move up and down. The design of the pressure plate matching the inner diameter of the dough drum ensures uniform extrusion of the dough, reduces dough residue, and ensures the stability and continuity of dough supply, laying the foundation for subsequent quantitative cutting.

[0036] Furthermore, the pressure plate is made of food-grade stainless steel, and a metal probe is fixedly installed at the bottom of the connecting box and on one side of the lead screw. The metal probe is used to detect the lifting position of the pressure plate to provide feedback for adjusting the amount of dough supplied.

[0037] The food-grade stainless steel pressure plate meets the hygiene requirements of food processing, preventing dough contamination. A metal probe detects the position of the pressure plate, allowing real-time monitoring of its pressing depth and thus determining the amount of dough squeezed. This information is fed back to the control system, which adjusts the dough feeding device accordingly for precise control of the dough supply.

[0038] Furthermore, a discharge pipe is vertically connected to the center of the bottom of the dough bucket. A clamp is fitted on the outer circumference of the discharge end of the discharge pipe. The clamp can hold and fix the reducer inserted at the end of the discharge pipe. The diameter of the dough extrusion can be adjusted by replacing the reducer with a different inner diameter.

[0039] The discharge pipe provides an output channel for the dough. The design of the clamp and reducer allows users to replace the reducer with one of different inner diameters according to actual needs, and the clamp ensures a stable connection. This flexible and convenient structure can adapt to the processing needs of dough of different diameters, improving the versatility of the equipment.

[0040] Furthermore, the cutting mechanism includes a first motor, which is fixedly mounted on the top of the side wall of the fixed plate. A turntable is fixedly connected to the end of the output shaft of the first motor. A connecting rod is rotatably connected to the surface of the turntable near the edge via a pin. A sliding plate is rotatably connected to the bottom end of the connecting rod via a pin. The sliding plate is slidably connected to the fixed plate in the horizontal direction. A cutter is detachably mounted on the bottom of the sliding plate via fastening bolts. The cutter can abut against the discharge end of the discharge pipe to cut the dough.

[0041] The first motor drives the turntable to rotate, and the rotational motion of the turntable is converted into the horizontal reciprocating motion of the slide plate through the connecting rod, which drives the cutter to achieve the cutting action. The detachable design of the cutter makes it easy to replace and maintain. Its abutment fit with the end of the discharge pipe ensures thorough cutting and ensures the integrity of the dough after division. This structure has stable transmission and high cutting efficiency.

[0042] Furthermore, a connecting plate is slidably connected to the bottom of the fixed plate in the horizontal direction, and an adjusting bolt is threaded through the surface of the connecting plate in the vertical direction. The top of the adjusting bolt is rotatably connected to the fixed plate. A first infrared sensing probe is fixedly installed on the surface of the connecting plate. The first infrared sensing probe is used to monitor the length of the dough extruded from the discharge pipe to provide feedback and control the cutting timing.

[0043] Rotating the adjusting bolt allows the connecting plate to slide horizontally, thereby adjusting the position of the first infrared sensor to accommodate dough length monitoring with different quantitative requirements. The first infrared sensor accurately monitors the extruded dough length, and when the set length is reached, a feedback signal controls the cutting mechanism to achieve quantitative cutting of the dough and improve segmentation accuracy.

[0044] Furthermore, a second infrared sensor is fixedly installed on the surface of the fixed plate and on one side of the turntable. The second infrared sensor is used to monitor the rotation angle of the turntable to provide feedback control on the start and stop status of the first motor.

[0045] The second infrared sensor monitors the rotation angle of the turntable, which determines the cutting position and stroke of the cutter. After the cutter completes one cutting action, the sensor sends a signal back to the control system, which controls the first motor to stop or reverse, ensuring the cutter resets, preventing excessive cutter movement, and improving the stability and safety of the cutting mechanism.

[0046] Furthermore, both outer walls of the dough bucket are integrally formed with locking blocks, and the top of the support frame is provided with locking slots corresponding to the positions of the two locking blocks. The locking blocks and locking slots can be plugged and unplugged. The top of the support frame is also fixedly provided with a bearing bracket, which is used to support the dough bucket. The dough bucket can be quickly disassembled and assembled through the cooperation of the locking blocks and locking slots. After assembly, the coaxiality of the dough bucket and the pressure plate can be guaranteed, so that the pressure plate can be coaxially extended into the inside of the dough bucket.

[0047] The insertion and removal of the locking blocks and slots allows for quick assembly and disassembly of the dough bucket, facilitating dough filling and equipment cleaning. The support brackets provide stable support. Simultaneously, this design ensures the coaxiality of the dough bucket and the pressure plate, guaranteeing the pressure plate smoothly inserts into the dough bucket and evenly compresses the dough, preventing uneven dough feeding caused by misalignment.

[0048] In summary, by setting up a dough feeding device that utilizes the transmission of a motor, worm gear lifter, and lead screw, along with a pressure plate adapted to the inner diameter of the dough bucket, stable and uniform extrusion of the dough is achieved. The addition of a metal probe further ensures precise and reliable control of the dough supply. The detachable design of the dough bucket and the adjustable reducer at the discharge end balance the ease of use of the equipment with the diverse processing needs for dough diameters.

[0049] The cutting mechanism, through ingenious mechanical transmission combined with precise monitoring and control by dual infrared sensor probes, ensures stable and efficient cutting action while accurately controlling the cutting timing and blade stroke, significantly improving the precision and safety of dough division.

[0050] This dough divider not only meets the quantitative dividing needs of dough of different specifications, but also performs excellently in terms of ease of operation, operational stability and hygiene safety. It is suitable for various pasta processing scenarios and can effectively improve the efficiency and quality of dough processing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
