Description

Technical Field

[0001] This application relates to the field of food processing technology, specifically a dough quantitative dividing mechanism. Background Technology

[0002] In the food processing industry, especially in the production of bread, pastries and other flour-based products, the quantitative division of dough is a process that helps ensure the consistency of product quality.

[0003] An existing patent (publication number: CN222340399U) discloses a dough quantitative segmentation device, relating to the field of dough segmentation technology. It includes a housing with a material hopper inside. A first electric telescopic rod is fixedly installed at the right end of the material hopper, and a push plate is fixedly connected to the output end of the first electric telescopic rod. A discharge structure is fixedly installed at the front of the housing. This invention's dough quantitative segmentation device, through the action of the discharge structure, uses the first electric telescopic rod to push the push plate towards the discharge plate, thereby squeezing the dough through the discharge plate and out of the material hopper. Then, a second electric telescopic rod is activated, driving a scraper to slide towards the discharge port of the discharge plate, thereby cutting and segmenting the dough. The two limiting plates slide in opposite directions, adjusting the size of the discharge port of the discharge plate, thus allowing the dough to be adjusted in shape and size according to actual use, improving the practicality of the dough quantitative segmentation device.

[0004] However, due to the high viscosity of the dough, dough easily sticks to the surface of the scraper during the cutting process. As the usage time increases, the dough adhering to the scraper surface will gradually accumulate, which can easily cause it to get entangled with the dough being cut later, affecting the cutting accuracy of the scraper and resulting in unevenly sized dough pieces, thus affecting product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a dough quantitative segmentation mechanism that has advantages such as bidirectional production and anti-sticking, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a dough quantitative dividing mechanism, including a frame and an extrusion cylinder installed at the top of the frame, both ends of the extrusion cylinder are provided with extrusion dies, a bidirectional extrusion screw is rotatably connected between the two extrusion dies, and a feed hopper is fixedly connected to the middle of the extrusion cylinder;

[0007] Both ends of the extrusion cylinder are fixedly connected to a fixed plate, and a cutting component is provided at the bottom of each of the two fixed plates.

[0008] The cutting assembly includes a mounting plate, which is tangentially arranged with its corresponding fixed plate. The fixed plate is rotatably connected to a cutting shaft arranged along the length of the extrusion cylinder, and a cutting blade is fixedly connected to one end of the cutting shaft.

[0009] Furthermore, the cutting assembly also includes a first L-shaped rod, the top end of which is fixedly connected to the mounting plate, and the bottom end of which is slidably fitted with two scrapers along the length of the extrusion cylinder. The two scrapers are located below the cutting blade, and the bottom end of the first L-shaped rod is chamfered.

[0010] With the above scheme, the cutting blade can slide on the first L-shaped rod by squeezing the scraper. During the cutting process, the scraper can scrape off the dough adhering to the surface of the cutting blade in time, preventing the dough from accumulating and affecting the cutting accuracy. The beveled edge setting at the bottom of the first L-shaped rod can prevent the scraper from flipping during the movement.

[0011] Furthermore, the cutting assembly also includes two reset discs, both of which are fixedly connected to the bottom end of the first L-shaped rod, and two scrapers are located between the two reset discs. A spring is fixedly installed between each reset disc and its corresponding scraper, and both springs are sleeved with the bottom end of the first L-shaped rod.

[0012] With the above solution, after the scraper removes the dough, the spring force can quickly reset the scraper so that the next scraping action can be performed, ensuring a continuous and stable scraping effect. At the same time, during the scraping process, it can ensure close contact between the scraper and the surface of the cutting blade.

[0013] Furthermore, the tops of the two scrapers are arranged in a Y-shape, and the bottoms of the two scrapers are in contact with each other.

[0014] With the above solution, the Y-shaped scraper can guide the cutting blade as it rotates into the scraper, making it easier for the cutting blade to enter between the two scrapers.

[0015] Furthermore, an anti-sticking component is installed on the outer surface of the first L-shaped rod. The anti-sticking component includes a second L-shaped rod. The other end of the second L-shaped rod is fixedly connected to a U-shaped spray box. The U-shaped spray box is located below the cutting component. The U-shaped spray box is concentrically arranged with the mounting plate. A set of atomizing nozzles is fixedly connected to each of the two inner sidewalls of the U-shaped spray box. A connecting pipe is fixedly connected to the outer surface of the U-shaped spray box.

[0016] The above solution connects the connecting pipe to the external pump input, and the pump outputs an anti-sticking liquid, such as cooking oil, to cover the surface of the cutting blade. This further prevents the cutting blade from sticking to the dough when cutting, reduces dough sticking, and improves cutting quality.

[0017] Furthermore, the anti-stick component also includes a fixing block, which is fixedly connected to the top of the U-shaped spray box, and a photoelectric switch is installed on the surface of the fixing block.

[0018] Through the above scheme, the photoelectric switch can monitor the position of the cutting blade in real time. When the cutting blade moves to the appropriate position, it controls the pump to start and accurately spray anti-stick liquid onto the surface of the cutting blade.

[0019] Furthermore, the two extrusion dies are respectively fixedly connected to their adjacent fixed discs by bolts.

[0020] The above solution facilitates the installation and disassembly of the extrusion die. When the extrusion die is worn or needs to be replaced with an extrusion die of a different specification, the operation can be carried out quickly, improving the maintenance efficiency and usage flexibility of the equipment.

[0021] Furthermore, one end of the bidirectional extrusion screw is fixedly connected to the external motor output end via a coupling.

[0022] Through the above solution, the coupling can effectively transmit the torque of the motor, enabling the extrusion screw to rotate stably, facilitating disassembly, maintenance, and replacement, and reducing equipment downtime.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This dough quantitative segmentation mechanism, by setting a bidirectional extrusion screw and extrusion dies at both ends, realizes bidirectional simultaneous extrusion of dough, improving production efficiency. With separate control of the speed of two motors, it can simultaneously produce and cut dough pieces of different weights.

[0025] By combining the cutting blade and scraper in the cutting assembly, along with the spring mechanism, dough adhering to the cutting blade surface is scraped off in a timely manner during the cutting process. This prevents dough accumulation from affecting cutting accuracy and ensures that the cut dough pieces are of uniform size. The anti-sticking assembly features a U-shaped spray box and atomizing nozzle, along with a photoelectric switch for real-time monitoring of the cutting blade position. This allows for precise spraying of anti-sticking liquid onto the cutting blade surface, further preventing dough from sticking to the blade during cutting, reducing dough adhesion, and improving cutting quality.

[0026] By using bolts to fix the extrusion die to the fixed plate, the extrusion die can be quickly installed and disassembled, which facilitates equipment maintenance and replacement of extrusion dies of different specifications, and improves the flexibility of equipment use.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Please see Figures 1-7 The dough quantitative segmentation mechanism in this embodiment includes a frame 1 and an extrusion cylinder 2 installed at the top of the frame 1. Both ends of the extrusion cylinder 2 are provided with extrusion molds 3. A bidirectional extrusion screw 4 is rotatably connected between the two extrusion molds 3. A feed hopper 5 is fixedly connected to the middle of the extrusion cylinder 2.

[0040] Both ends of the extrusion cylinder 2 are fixedly connected to fixed plates 6. The bottom of each fixed plate 6 is equipped with a cutting component 7. Using the bidirectional extrusion screw 4 and the extrusion dies 3 at both ends, dough can be extruded simultaneously in both directions, improving production efficiency. At the same time, the cutting component 7 can divide the extruded dough into pieces. The two extrusion dies 3 are respectively fixedly connected to the adjacent fixed plates 6 by bolts, which facilitates the installation and disassembly of the extrusion dies 3. When the extrusion die 3 is worn or needs to be replaced with an extrusion die 3 of a different specification, it can be operated quickly, improving the maintenance efficiency and usage flexibility of the equipment. One end of the bidirectional extrusion screw 4 is fixedly connected to the external motor output end through a coupling. The coupling can effectively transmit the torque of the motor, making the extrusion screw rotate stably, which is convenient for disassembly, maintenance and replacement, reducing equipment downtime.

[0041] The cutting assembly 7 includes a mounting plate 701, which is tangentially arranged with its corresponding fixed plate 6. The fixed plate 6 is rotatably connected to a cutting shaft 702 arranged along the length of the extrusion cylinder 2. One end of the cutting shaft 702 is fixedly connected to a cutting blade 703. By controlling the rotation speed of the cutting shaft 702, the cutting frequency of the cutting blade 703 on the dough can be precisely controlled, thereby achieving control over the size of the dough pieces. One end of each of the two cutting shafts 702 is fixedly connected to the output end of an external motor.

[0042] The cutting assembly 7 also includes a first L-shaped rod 704. The top end of the first L-shaped rod 704 is fixedly connected to the mounting plate 701. Two scrapers 705 are slidably sleeved at the bottom end of the first L-shaped rod 704 along the length of the extrusion cylinder 2. The two scrapers 705 are located below the cutting blade 703. The bottom end of the first L-shaped rod 704 is beveled. The cutting blade 703 squeezes the scrapers 705 so that they can slide on the first L-shaped rod. During the process of the cutting blade 703 cutting the dough, the scrapers 705 can scrape off the dough adhering to the surface of the cutting blade 703 in time to prevent the dough from accumulating and affecting the cutting accuracy. The beveled edge at the bottom end of the first L-shaped rod can prevent the scrapers 705 from flipping during the movement.

[0043] The cutting assembly 7 also includes two reset discs 706, both of which are fixedly connected to the bottom end of the first L-shaped rod 704. Two scrapers 705 are located between the two reset discs 706. A spring 707 is fixedly installed between each reset disc 706 and its corresponding scraper 705. Both springs 707 are sleeved with the bottom end of the first L-shaped rod 704. When the scraper 705 scrapes away the dough, the elastic force of the spring 707 can quickly reset the scraper 705 so that it can perform the next scraping action, ensuring a continuous and stable scraping effect. At the same time, during the scraping process, it can ensure close contact between the scraper 705 and the surface of the cutting blade 703. The top ends of the two scrapers 705 are set in a Y-shaped structure, and the bottom ends of the two scrapers 705 abut against each other. The Y-shaped scraper 705 can guide the cutting blade 703 when it rotates into the scraper 705, making it easier for the cutting blade 703 to enter between the two scrapers 705.

[0044] An anti-sticking component 8 is installed on the outer surface of the first L-shaped rod 704. The anti-sticking component 8 includes a second L-shaped rod 801. The other end of the second L-shaped rod 801 is fixedly connected to a U-shaped spray box 802. The U-shaped spray box 802 is located below the cutting component 7 and is concentrically arranged with the mounting plate 701. A set of atomizing nozzles 803 are fixedly connected to the two inner side walls of the U-shaped spray box 802. A connecting pipe 804 is fixedly connected to the outer surface of the U-shaped spray box 802. The connecting pipe 804 is connected to the input end of the pump body in the outside, and the anti-sticking liquid is output through the pump body. For example, cooking oil can be used to coat the surface of the cutting blade 703, further preventing the cutting blade 703 from sticking to the dough when cutting it, reducing dough sticking and improving cutting quality. The anti-stick component 8 also includes a fixing block 805, which is fixedly connected to the top of the U-shaped spray box 802. A photoelectric switch 806 is installed on the surface of the fixing block 805. The photoelectric switch 806 can monitor the position of the cutting blade 703 in real time. When the cutting blade 703 moves to the appropriate position, it controls the pump to start and accurately spray the anti-stick liquid onto the surface of the cutting blade 703.

[0045] The working principle of the above embodiment is as follows: The dough to be divided is fed into the extrusion cylinder 2 through the feed hopper 5. The feed hopper 5 is fixedly connected to the middle of the extrusion cylinder 2. The dough enters the extrusion cylinder 2 under the action of gravity. The external motor is started, and the motor transmits the torque to the bidirectional extrusion screw 4 through the coupling, so that the bidirectional extrusion screw 4 rotates between the two extrusion dies 3. Due to the special design of the bidirectional extrusion screw 4, during its rotation, the dough entering the extrusion cylinder 2 is simultaneously squeezed to both ends of the extrusion cylinder 2. Under the push of the extrusion screw, the dough is extruded through the extrusion dies 3 at both ends, realizing bidirectional simultaneous extrusion of dough, which improves production efficiency. By controlling the speed of the two motors connected to the cutting shaft 702 separately, dough pieces of different weights can be produced and cut at the same time.

[0046] When the rotating cutter 703 rotates to the extrusion port, it cuts the dough extruded from the extrusion die 3, dividing the continuously extruded dough into pieces. During the cutting process, the cutter 703 presses against two scrapers 705 located below and slidably fitted at the bottom of the first L-shaped rod 704. The tops of the two scrapers 705 are Y-shaped, which guides the cutter 703 as it rotates into the scrapers 705, facilitating its smooth entry between the two scrapers 705. As the cutter 703 presses, the scrapers 705 slide along the length of the extrusion cylinder 2 on the first L-shaped rod 704. During the sliding process... The scraping action removes dough adhering to the surface of the cutting blade 703, ensuring that the cut dough pieces are of uniform size. The bottom end of the first L-shaped rod 704 is beveled to prevent the scraper 705 from flipping during movement. When the cutting blade 703 leaves the scraper 705, a spring 707 is fixedly installed between each reset disc 706 and its corresponding scraper 705, and both springs 707 are sleeved with the bottom end of the first L-shaped rod 704. The elasticity of the springs 707 will cause the scraper 705 to quickly reset so that the next scraping action can be performed, ensuring a continuous and stable scraping effect. At the same time, during the scraping process, it can ensure that the scraper 705 and the surface of the cutting blade 703 are in close contact.

[0047] A photoelectric switch 806 is mounted on the surface of the fixing block 805 fixedly connected to the top of the U-shaped spray box 802. The photoelectric switch 806 can monitor the position of the cutting blade 703 in real time. When the cutting blade 703 moves to the photoelectric switch 806, the photoelectric switch 806 transmits a signal to the device controlling the pump body, controlling the pump body to start. The pump body delivers anti-sticking liquid, such as cooking oil, to the U-shaped spray box 802 through the connecting pipe 804. The U-shaped spray box 802 is located below the cutting assembly 7 and is concentrically set with the mounting plate 701. A set of atomizing nozzles 803 are fixedly connected to its two inner side walls. The anti-sticking liquid is sprayed onto the surface of the cutting blade 703 in a mist form through the atomizing nozzles 803 to prevent the cutting blade 703 from sticking to the dough when cutting, reducing dough sticking and improving cutting quality.

[0048] When the extrusion die 3 is worn or needs to be replaced with an extrusion die 3 of a different specification, since the two extrusion dies 3 are respectively fixedly connected to their adjacent fixed plates 6 by bolts, you can simply use a tool to unscrew the bolts to remove the extrusion die 3 from the fixed plate 6, then install the new extrusion die 3, and then tighten the bolts to fix it.
