Description

Technical Field

[0001] This invention relates to an integrated device for quantitatively dividing and rounding dough, belonging to the field of food machinery. Background Technology

[0002] Steamed buns, a traditional Chinese steamed bread with a history of thousands of years, serve as a staple food, breakfast, and snack, making them a beloved treat. Bread, as a Western staple food, is being localized and developed by incorporating Chinese fillings such as taro paste, salted egg yolk, and mochi to create a new trend in Chinese-style bread. This integration of Chinese and Western culinary innovation enriches the dietary choices of the population and promotes the diversification of pastry categories.

[0003] Whether it's traditional Chinese pastries or the localization of Western staple foods, it's often necessary to cut the kneaded dough into smaller dough balls according to the required weight, and then roll and shape the smaller dough balls into rounds for subsequent filling or shaping processes.

[0004] In existing technologies, the main technical solutions for quantitatively dividing and rounding dough are as follows: Firstly, as disclosed in Chinese invention patent CN210445478U, an intelligent dough dividing and rounding machine uses an extrusion device to compress the dough into strips via a connecting pipe. The strips are then cut into pieces by a cutting device. The cut dough can be either directly conveyed to the next process or guided through a guide channel to a rounding device for rounding before being output by the conveyor. While this solution integrates the dividing and rounding functions, the dough tends to stick to the inner wall of the equipment during extrusion and compression. Furthermore, the method of compressing into strips before cutting makes it difficult to achieve precise weight control for each dough piece. Additionally, the extrusion and compression devices have complex structures, leading to issues of dough sticking and residue during transport.

[0005] Secondly, consider the automatic bread-rolling system disclosed in Chinese invention patent CN202021097647.8. This system involves dividing the dough using a quantitative slitting machine, conveying it via a first belt to a first umbrella-shaped rounding machine for initial rounding, followed by proofing in an intermediate proofing box, and then sequentially passing through a first and second rolling and forming machine for rolling and shaping. Finally, it enters the second umbrella-shaped rounding machine for a second rounding. This solution uses multiple independent devices connected in series to complete the slitting, rounding, and shaping processes. The equipment occupies a large area, and the connections between devices rely on multiple conveyor belts, resulting in a loose overall structure. Furthermore, the proofing and rolling processes add unnecessary steps for dough processing scenarios requiring only simple slitting and rounding, reducing production efficiency.

[0006] Thirdly, as disclosed in Chinese invention patent CN115918694B, a dough dividing and rounding machine uses a feeding mechanism to feed dough into a cutting mechanism, where two sets of cutting blades divide the dough into strips. A pushing mechanism then pushes the strips into a dividing mechanism, which quantitatively divides the strips into smaller pieces. These smaller pieces fall into a rounding mechanism for rounding, and are finally output by an output mechanism. While this solution achieves automated continuous production of dividing and rounding, its cutting mechanism can only perform preliminary strip division of the dough, making it difficult to achieve uniformity in the cross-sectional shape and size of the strips, thus affecting the accuracy of subsequent quantitative division. Furthermore, its rounding mechanism uses an outer roller and inner roller combination, which makes the dough prone to sticking together during rounding in the kneading trough, resulting in an unsatisfactory rounding effect. In addition, the conveying path for the dough is relatively long, and there is a lack of anti-sticking measures when the dough flows between different mechanisms.

[0007] In addition, a common existing technology involves placing a pair of relatively rotating cutters at the bottom of an inverted conical hopper. Large dough balls inside the hopper slide down to the rotating cutters under gravity for cutting. The drawback of this method is that gravity alone cannot ensure the large dough balls slide smoothly, and the dough sticks to the inner wall of the hopper, breeding bacteria and affecting food safety. After cutting, the dough still needs to be manually rolled into cylindrical shapes, pinched into portions, weighed, and rolled into balls, consuming a large amount of manpower, resulting in extremely high costs and low efficiency.

[0008] In summary, existing dough cutting and rounding equipment has the following main shortcomings: (1) During the conveying and cutting process, the dough is prone to sticking to the inner wall of the equipment, conveying rollers, cutters and other parts, affecting the normal operation of the equipment and food hygiene and safety; (2) Quantitative cutting and rounding are usually completed by separate equipment or workstations, the equipment structure is loose, the area occupied is large, and the process connection requires manual or additional conveying devices; (3) There is a lack of truly integrated design for multi-station parallel operation, making it difficult to achieve integrated continuous and efficient production from large dough balls to quantitative small dough balls and complete rounding. Therefore, it is urgent to develop a dough processing device that can simultaneously solve the problems of dough anti-sticking and integrated mechanical linkage of quantitative cutting and rounding.

[0018] The frame section (J) includes a frame (60), a shock-absorbing column (61), a mounting base plate (62), and a base (63); the mounting base plate (62) is mounted on the frame (60) via the shock-absorbing column (61), and the base (63) is mounted on the mounting base plate (62); the output section (S) includes a conveyor belt (119), which is mounted on one side of the turntable (105) for receiving and conveying a fixed amount of dough after rounding; the hopper section (L) also includes a hopper front baffle (42), which is parallel to the hopper wall panel (1) and forms a gap between them, and the hopper front baffle (42) is attached to the front end face of the left powder baffle (23) and the right powder baffle (28) and installed together.

[0019] The advantages of this invention are: 1. The material hopper section adopts a graded powder spreading design with double brushes and a powder-splitting plate. The first and second brushes, driven by the brush motor, feed and evenly distribute the powder in stages. The powder in the storage hopper is evenly spread into the cutting hopper through the powder-splitting plate. Combined with the V-shaped groove structure evenly distributed on the surface of the conveyor roller, the powder is evenly carried out while conveying the dough. This completely avoids the dough sticking to the wall, conveyor roller and inner wall of the equipment. It effectively solves the problems of slippage and bacterial growth caused by dough sticking in traditional equipment, ensuring smooth operation of the equipment and food hygiene and safety.

[0020] 2. The slitting section is set up with a turntable cycle working mode. Multiple sets of mold cavity components are evenly distributed along the circumference of the turntable. Through the asynchronous or synchronous switching rotation of the quantitative cam and the turntable, the three stations complete the quantitative slitting of dough at station 1, the quantitative dough rounding and shaping at station 2, and the automatic material pushing and unloading at station 3. The three stations work synchronously and in parallel, and the processes are seamlessly connected, which greatly shortens the production cycle and significantly increases the output per unit time.

[0021] 3. Through the coordinated action of a single motor (main motor) and transmission components such as eccentric blocks, sprocket cams, dial plates, planetary gear mechanisms, and ratchet pawls, precise switching between two working conditions can be achieved: the quantitative cam rotates 90° independently (with the turntable stationary) and the quantitative cam rotates 90° synchronously in the opposite direction to the turntable 105. This enables continuous mechanical production of the entire process of dough quantitativeization, cutting, rounding, and discharge, without the need for manual intervention, thus significantly reducing labor costs.

[0022] 4. The bottom of the mold cavity adjustment block of the mold cavity assembly (MQ) is provided with a quantitative arc surface, which abuts against the push roller to ensure that the polygonal cavity volume of the mold cavity remains constant; the limiting pins on both sides of the bottom of the mold cavity adjustment block can prevent the mold cavity adjustment block from falling out, so as to achieve precise and consistent quality of dough that is forcefully squeezed into the mold cavity each time; combined with the real-time detection and feedback control of the presence or absence of dough by the through-beam photoelectric sensor, the accuracy of quantitative cutting is further guaranteed.

[0023] 5. The rounding mold of the rounding part performs a planar circular motion under the transmission action of the rounding motor, drive pulley, transmission belt and eccentric shaft. The longitudinal sliding seat and the kneading sliding seat slide on the longitudinal guide shaft and the transverse guide shaft respectively to realize the compound motion in the two-dimensional plane. With the abutment of the lifting rod and the second lifting bearing, the rounding mold is lifted and lowered to ensure that the dough is fully and evenly kneaded in the mold cavity. The rounded dough has a regular shape and a smooth surface.

[0024] 6. The presence of dough in the cutting chamber is detected in real time by a photoelectric sensor. When the cutting piston moves to the left, the photoelectric sensor detects the dough signal and reaches the set filtering time. When the cutting piston moves back to the right, the cutter motor and brush motor stop working, realizing on-demand feeding and automatic start-stop control, avoiding idling and ineffective cutting, saving energy and reducing equipment wear.

[0025] 7. The material hopper, slitting, rounding, and output sections are integrated into one unit. The material hopper is located above the slitting section, the rounding section is located directly above the center of the turntable of the slitting section, and the output section is located on one side of the slitting section. The functional components are rationally arranged in space and have a compact structure. Compared with the traditional production line with multiple independent equipment connected in series, it greatly reduces the equipment footprint and the factory space requirements.

[0026] 8. The cutter motor in the hopper section drives the left cutter shaft, the right cutter shaft, and the conveyor rollers on both sides to rotate synchronously through the right double-row sprocket, the first chain, and the second chain. The chain drive has strong load-bearing capacity and precise transmission ratio. The differentiated design of the slow sprocket, the medium sprocket, and the fast sprocket allows each conveyor roller to rotate at a different speed, which facilitates the smooth falling of the dough. At the same time, the modularity of each component is high, which facilitates daily maintenance and cleaning. Attached Figure Description

The output section S is installed on one side of the cutting section F and is used to transport the rounded dough to the next work station; The turntable 105 of the slitting section F has multiple sets of mold cavity components MQ evenly distributed along its circumference. The slitting section F rotates asynchronously or synchronously with the turntable 105 via a quantitative cam 93, driving each set of mold cavity components MQ to sequentially perform quantitative slitting, rounding and shaping, and material pushing and unloading operations.

[0043] In this invention, the hopper section L is fixedly connected to the left rear wall panel 2 and the right rear wall panel 3 via the hopper wall panel 1 and wall panel support shaft 4 to form a stable frame support. Multiple conveying roller shafts 5 are rotatably installed in a V-shape distribution between the hopper wall panel 1 and the left rear wall panel 2, and between the hopper wall panel 1 and the right rear wall panel 3, respectively, from the upper left to the lower right and from the upper right to the lower left. Each conveying roller shaft 5 has a conveying roller 8 with evenly distributed V-shaped grooves at its front end. The V-shaped distribution of the conveying roller assembly allows the dough to slide smoothly under gravity, while the V-shaped grooves on the surface of the conveying roller 8, during rotation, help to move the dough in the powder storage hopper. The powder is evenly carried out and coated on the surface of the dough; the first and second powder storage bins are formed by the left side plate 20, right side plate 22, left powder baffle plate 23, right powder baffle plate 28, powder strainer plate 24 and inner powder baffle plate 25, and the first brush 30 and second brush 35 are rotatably installed above and below the powder strainer plate 24. Driven by the brush motor 31, the double brushes deliver powder step by step and evenly distribute the powder. The flour is evenly sprinkled into the cutting section F through the powder strainer plate 24, which avoids the dough from sticking to the wall, the conveying roller and the inner wall of the equipment. The material bin L is used to store the dough and cut the dough into small pieces before supplying it to the cutting section F.

[0044] The slitting section F, via the drive sprocket 66 and eccentric block 67 mounted on the output shaft of the main motor 64, drives the sprocket cam 78 to rotate via the cam chain 80. The lifting cam 7802 and intermittent cam 7803 on the sprocket cam 78 respectively drive the lifting arm 82 and intermittent arm 83 to swing. At the same time, the transmission shaft 6701 of the eccentric block 67 drives the slitting piston 76 to reciprocate within the slitting chamber FQC via the connecting plate 68, the arm 71, and the rocker arm 73. The eccentric block 67 also drives the dial 89 to reciprocate via the locking block 69 and the curved connecting plate 88. The pawl 99 on the dial 89 engages with the stepped notch on the outer circumference of the positioning plate 91, and the intermittent arm 83... Under the synergistic effect of the conical protrusions embedding into or detaching from the conical groove of the positioning disk 91, the precise switching between two working conditions is achieved through the meshing transmission of the transmission fastener 104, the dial gear 94, the cam gear 95 and the planetary gear 97: the quantitative cam 93 rotates 90° independently (at which time the turntable 105 is stationary) or the quantitative cam 93 and the turntable 105 rotate 90° synchronously in opposite directions. This drives multiple sets of mold cavity components MQ evenly distributed on the turntable 105 to sequentially and cyclically perform quantitative cutting, rounding and shaping and material pushing and discharging operations. The three stations operate synchronously and in parallel with seamless process connection. Among them, the cutting part F is used to quantitatively cut small pieces of dough according to a predetermined weight and rotate them to the rounding station and the discharging station.

[0045] Each set of mold cavities 113 of the mold cavity assembly MQ has multiple polygonal cavities LBKQ arranged in parallel intervals, each with a mold cavity adjustment block 114 slidably installed inside. The quantitative arc surface at the bottom of the mold cavity adjustment block 114 abuts against the push roller 111 to ensure that the volume of the polygonal cavity LBKQ remains constant, so as to achieve precise and consistent quality of dough that is forcefully squeezed into the mold cavity 113 by the cutting piston 76 each time. The limiting pins 115 on both sides of the bottom of the mold cavity adjustment block 114 prevent the mold cavity adjustment block 114 from falling out of the polygonal cavity LBKQ. At the same time, the photoelectric sensor 36 installed on the front stop 27 and the corresponding position of the material bin wall plate 1 detects in real time whether there is dough in the cutting bin FQC. When the cutting piston 76 detects the dough signal during the leftward movement and reaches the set filtering time, the cutting piston 76 retracts to the right and the cutter motor 12 and the brush motor 31 stop working, so as to achieve dual protection of on-demand feeding and quantitative accuracy.

[0046] A rotating seat 4501 is installed on the rounding base 45 of the rounding section C. A pulley support sleeve 46 is rotatably installed on the rotating seat 4501. The rounding motor 47 drives the pulley support sleeve 46 to rotate through the drive pulley 48 and the transmission belt 49. The eccentric shaft section at the lower end of the eccentric shaft 57, which is fixedly installed in the shaft hole of the pulley support sleeve 46, is rotatably connected to the center hole of the kneading sliding seat 54 through a bearing. Under the action of the eccentric shaft section, the kneading sliding seat 54 is driven to perform a compound circular motion in a two-dimensional plane on the longitudinal guide shaft 50 and the transverse guide shaft 52. The rounding mold 56 installed on the rounding seat 55 moves accordingly and fully kneads the dough in the mold cavity 113. At the same time, the lower end face of the lifting rod 59 abuts against the second lifting bearing 85 of the cutting section F. Under the drive of the lifting rotating arm 82, the rounding mold 56 is lifted and lowered to ensure that the rounding action is precisely coordinated with the rotation of the turntable 105. The rounding section C is used to round and shape the dough after quantitative cutting.

[0047] The frame section J forms a stable supporting foundation. The hopper section L is located above the cutting section F, the rounding section C is located directly above the turntable center of the cutting section F, and the output section S is located on one side of the cutting section F. The spatial layout of each functional component is reasonable. The main motor 64, a single power source, achieves full-process mechanical linkage through the above-mentioned cam drive, chain drive, and planetary gear mechanism without manual intervention. The frame section J is used to provide a supporting foundation for the whole machine, and the output section S is used to transport the rounded dough to the next station.

[0048] The hopper section L includes a hopper wall panel 1, a left rear wall panel 2, a right rear wall panel 3, a wall panel support shaft 4, a conveyor roller shaft 5, a left cutter shaft 6, a right cutter shaft 7, a conveyor roller 8, a cutter 9, a left side plate 20, a right side plate 22, a left powder baffle plate 23, a powder leakage plate 24, an inner powder baffle plate 25, a right powder baffle plate 28, a first brush 30, a second brush 35, a brush motor 31, a powder storage hopper, and a cutter motor 12; the hopper wall panel 1 and the left rear wall panel 2. Parallel to each other and spaced apart, the silo wall panel 1 and the right rear wall panel 3 are parallel to each other and spaced apart; there are multiple wall panel support shafts 4, each wall panel support shaft 4 is fixedly installed between the silo wall panel 1 and the left rear wall panel 2, and between the silo wall panel 1 and the right rear wall panel 3, so that the silo wall panel 1, the left rear wall panel 2 and the right rear wall panel 3 are fixedly connected as one unit; the silo wall panel 1 and the left rear wall panel 2 are rotated sequentially from the upper left to the lower right. The equipment is equipped with multiple conveyor rollers 5. Multiple conveyor rollers 5 are rotatably installed between the hopper wall panel 1 and the right rear wall panel 3, from the upper right to the lower left. All the conveyor rollers 5 together form a V-shaped conveyor roller assembly. A conveyor roller 8 is provided at the front end of each conveyor roller 5, and V-shaped grooves are evenly distributed on the surface of the conveyor roller 8. Multiple conveyor rollers 5 are rotatably installed between the hopper wall panel 1 and the left rear wall panel 2, from the upper left to the lower right. Multiple conveyor rollers 5 are rotatably installed between the hopper wall panel 1 and the right rear wall panel 3, from the upper right to the lower left. All the conveyor rollers 5 together form a V-shaped conveyor roller assembly. Under its own weight, the large dough ball naturally slides down the V-shaped slope to the bottom of the conveyor roller assembly. The left and right conveyor rollers 8 simultaneously rotate and convey the dough towards the center and downwards, actively pulling the dough down, effectively avoiding the problems of dough slippage and blockage caused by gravity alone in traditional equipment.

[0049] The left cutting shaft 6 is rotatably installed between the hopper wall panel 1 and the left rear wall panel 2, and the right cutting shaft 7 is rotatably installed between the hopper wall panel 1 and the right rear wall panel 3. Cutting blades 9 are respectively provided at the front ends of the left cutting shaft 6 and the right cutting shaft 7. The left cutting shaft 6 and the right cutting shaft 7 are respectively located on both sides below the V-shaped distributed conveyor roller assembly. The left side plate 20 and the right side plate 22 are respectively installed on the front sides of the hopper wall plate 1. The left powder baffle plate 23 is installed above the front of the left side plate 20. The right powder baffle plate 28 is installed on the upper part of the front of the right side plate 22. The powder leakage plate 24 is installed between the left side plate 20 and the inner powder baffle plate 25. A powder leakage hole is provided on the powder leakage plate 24. The first powder storage bin is formed between the hopper wall panel 1, the left side panel 20, the left powder baffle 23, the powder leakage panel 24, and the inner powder baffle 25; the second powder storage bin is formed between the hopper wall panel 1, the right side panel 22, and the right powder baffle 28; the functions of flour storage, conveying, powdering, dough conveying, and cutting are integrated into one unit, eliminating the need for an external powdering device, saving installation space, and facilitating daily maintenance and cleaning.

[0050] The first brush 30 is rotatably mounted above the powder-straining plate 24, and the second brush 35 is rotatably mounted below the powder-straining plate 24. The brush motor 31 drives the first brush 30 and the second brush 35 to rotate, so as to gradually sprinkle the flour in the first and second powder storage bins into the cutting section F through the powder-straining plate 24. Each conveying roller shaft 5 has a conveying roller 8 at its front end. V-shaped grooves are evenly distributed on the surface of the conveying roller 8. While the conveying roller 8 rotates to convey the dough, the V-shaped grooves evenly carry out the flour in the powder storage bins and coat the surface of the dough. An isolation layer is formed between the dough and the conveying roller 8, effectively preventing the dough from sticking to the roller and the material from getting stuck. At the same time, the first brush 30 is rotatably installed above the powder-straining plate 24, and the second brush 35 is rotatably installed below the powder-straining plate 24. The brush motor 31 drives the first brush 30 and the second brush 35 to rotate, so that the flour in the first powder storage bin and the second powder storage bin is sprinkled into the cutting part F step by step through the powder-straining plate 24, realizing multi-point and all-round anti-sticking treatment of the dough. From the structural design, the technical problem of dough sticking to the wall and not sliding smoothly is completely solved.

[0051] The cutter motor 12 is connected to the left cutter shaft 6 and the right cutter shaft 7 respectively, and is used to drive the cutters 9 on both sides to rotate relative to each other to cut the dough.

[0052] The hopper section L also includes a left stop block 26, a front stop block 27, and a through-beam photoelectric sensor 36. The left stop block 26 is installed at the lower end of the left side plate 20, the front stop block 27 is installed between the left stop block 26 and the right side plate 22, and the through-beam photoelectric sensor 36 is installed at the corresponding position between the front stop block 27 and the hopper wall plate 1, used to detect whether there is dough in the cutting section F. The through-beam photoelectric sensor 36, installed at the corresponding position between the front stop block 27 and the hopper wall plate 1, detects in real time whether there is dough in the cutting chamber FQC of the cutting section F. When sufficient dough is detected in the cutting chamber FQC, the cutter motor 12 and the brush motor 31 stop operating, realizing on-demand feeding, avoiding idling and ineffective cutting, saving energy, and reducing equipment wear.

[0053] The hopper section L also includes a hopper front baffle 42, which is parallel to the hopper wall panel 1 and forms a gap with it. The hopper front baffle 42 is installed together with the front end faces of the left powder baffle 23 and the right powder baffle 28.

[0054] The hopper section L also includes a right double-row sprocket 10, a left double-row sprocket 15, a slow sprocket 17, a middle sprocket 18, a fast sprocket 19, a first chain 37, a second chain 40, a first transition wheel 38, a second transition wheel 39, and a third transition wheel 41; The right double-row sprocket 10 includes a first sprocket 1001 and a second sprocket 1002, which are mounted on the rear end of the right cutter shaft 7; the left double-row sprocket 15 includes a third sprocket 1501 and a fourth sprocket 1502, which are mounted on the rear end of the left cutter shaft 6. Multiple conveyor roller shafts 5 extending backward through the left rear wall panel 2 are respectively equipped with a slow sprocket 17, a medium sprocket 18, and a fast sprocket 19 on the left side; multiple conveyor roller shafts 5 extending backward through the right rear wall panel 3 are respectively equipped with a slow sprocket 17, a medium sprocket 18, and a fast sprocket 19 on the right side; the three conveyor rollers 8 on the same side rotate at different speeds, with the speed gradually increasing from the upper left to the lower right or from the upper right to the lower left, forming a speed gradient, accelerating the dough to slide downward, and preventing the dough from accumulating between the conveyor rollers.

[0055] The first chain 37 passes sequentially around the first sprocket 1001, the first transition wheel 38, the slow sprocket 17, the middle sprocket 18 and the fast sprocket 19 located on the right rear wall panel 3, the second transition wheel 39 and the third sprocket 1501, and transmits the power of the cutter motor 12 to each conveying roller shaft 5 located on the right rear wall panel 3 and the left cutter shaft 6, so that each conveying roller 8 located on the right side and the cutter 9 on the left cutter shaft 6 rotate synchronously; The second chain 40 passes sequentially around the second sprocket 1002, the third transition wheel 41, the slow sprocket 17, the middle sprocket 18 and the fast sprocket 19 located on the left rear wall plate 2 side and the fourth sprocket 1502, transmitting the power of the cutter motor 12 to each conveying roller shaft 5 located on the left rear wall plate 2 side and the right cutter shaft 7, so that each conveying roller 8 located on the left side and the cutter 9 on the right cutter shaft 7 rotate synchronously; The cutter 9 on the left cutter shaft 6 and the cutter 9 on the right cutter shaft 7 rotate relative to each other under the drive of the cutter motor 12, cutting the dough into small pieces.

[0056] Through the synchronous transmission of the double chain, the cutter 9 on the left cutter shaft 6 and the cutter 9 on the right cutter shaft 7 achieve precise relative rotation, continuously and evenly cutting the dough into small pieces, achieving consistent cutting efficiency and dough piece size.

[0057] The working principle of the hopper section L of this invention is as follows: Initial state: Flour is placed into the first powder storage bin formed between the hopper wall plate 1, the left side plate 20, the left powder baffle plate 23, the powder leakage plate 24 and the inner powder baffle plate 25, and the second powder storage bin formed between the hopper wall plate 1, the right side plate 22 and the right powder baffle plate 28; at the same time, the large dough to be processed is placed above the V-shaped distributed conveyor roller assembly.

[0058] Operating status: When the cutter motor 12 starts, it drives the right cutter shaft 7 to rotate. The right double-row sprocket 10 installed at the rear end of the right cutter shaft 7 rotates accordingly. The first sprocket 1001 and the second sprocket 1002 of the right double-row sprocket 10 drive the first chain 37 and the second chain 40 to rotate synchronously, respectively. The first chain 37 passes through the first sprocket 1001, the first transition wheel 38, the slow sprocket 17, the middle sprocket 18 and the fast sprocket 19 located on the right rear wall plate 3, the second transition wheel 39, and the third sprocket 1501 installed at the rear end of the left cutter shaft 6, transmitting power to each conveyor roller shaft 5 located on the right rear wall plate 3 and the left cutter shaft 6. The second chain 40 passes through the second sprocket 1002, the third transition wheel 41, and the first chain 37 and the second chain 40 located on the left rear wall plate 3. The slow sprocket 17, medium sprocket 18, and fast sprocket 19 on one side of plate 2, and the fourth sprocket 1502 installed at the rear end of the left cutter shaft 6, transmit power to each conveying roller shaft 5 located on one side of the left rear wall plate 2 and the right cutter shaft 7. At the same time, the brush motor 31 starts, driving the first brush 30 on the first brush shaft 29 and the second brush 35 on the second brush shaft 34 to rotate slowly. The flour in the first and second powder storage bins is first carried by the first brush 30 into the powder leakage plate 24, and then passes through the powder leakage hole of the powder leakage plate 24 and falls onto the second brush 35. Then, the second brush 35 is rotated and evenly sprinkled into the slitting bin FQC of the slitting section F. At the same time, the V-shaped groove on the surface of the conveying roller 8 also carries out the flour in the powder storage bin during the rotation, forming a double powder sprinkling effect.

[0059] Dough conveying and cutting: The large dough ball slides down above the V-shaped conveyor roller assembly under its own weight and the traction of the left and right conveyor rollers 8. The left conveyor rollers 8 rotate clockwise (viewed from the front) at a speed from slow to fast, driven by the slow sprocket 17, the medium sprocket 18 and the fast sprocket 19. The right conveyor rollers 8 rotate counterclockwise (viewed from the front) at a speed from slow to fast. The V-shaped grooves on the left and right conveyor rollers 8 evenly carry out the flour and coat the surface of the dough during the rotation to prevent the dough from sticking together. After the dough is conveyed to the bottom, the cutter 9 on the left cutter shaft 6 and the cutter 9 on the right cutter shaft 7 rotate relative to each other under the drive of the cutter motor 12 to cut the dough into small pieces. The cut pieces of dough fall into the cutting chamber FQC of the cutting section F. At the same time, a small amount of flour sprinkled on the second brush 35 covers the surface of the dough to prevent the dough from sticking together again during subsequent processing.

[0060] Feedback Control: A through-beam photoelectric sensor 36, installed at the position corresponding to the front stop 27 and the hopper wall panel 1, detects in real time whether there is dough in the slitting chamber FQC. When there is enough dough in the slitting chamber FQC, the through-beam photoelectric sensor 36 continuously detects a signal. When the slitting piston 76 retracts to the right, the cutter motor 12 and the brush motor 31 do not start, and the feeding stops. When there is not enough dough in the slitting chamber FQC, the through-beam photoelectric sensor 36 does not detect a signal. When the slitting piston 76 retracts to the right, the cutter motor 12 and the brush motor 31 start a working cycle to replenish the dough in the slitting chamber FQC. This cycle repeats to achieve on-demand feeding and automatic start / stop control.

[0061] The slitting section F includes a main motor 64, a drive sprocket 66, an eccentric block 67, a connecting plate 68, a locking block 69, a rotating arm 71, a rocker arm shaft 72, a rocker arm 73, a push bearing 74, a push block 75, a slitting piston 76, a rocker arm bearing seat 77, a sprocket cam 78, a cam support shaft 79, a cam chain 80, a rotating arm support shaft 81, a lifting rotating arm 82, an intermittent rotating arm 83, an intermittent torsion spring 87, a curved connecting plate 88, a dial 89, a turntable shaft 90, a positioning plate 91, a quantitative cam shaft 92, a quantitative cam 93, a dial gear 94, a cam gear 95, a planetary flange 96, a planetary gear 97, a pawl 99, a compression spring 100, a transmission fastener 104, a turntable 105, a turntable end plate 106, a toggle assembly BD, a mold cavity assembly MQ, and a slitting chamber FQC.

The lifting arm 82 is equipped with a first lifting bearing 84 that abuts against the lifting cam 7802 and a second lifting bearing 85 that abuts against the rounded part C. One end of the intermittent rotating arm 83 is equipped with an intermittent bearing 86 that abuts against the intermittent cam 7803, and the other end of the intermittent rotating arm 83 is equipped with a tapered protrusion. The intermittent torsion spring 87 is fitted on the rotating arm support shaft 81, and the U-shaped end of the intermittent torsion spring 87 presses against the tapered protrusion of the intermittent rotating arm 83. One end of the curved connecting plate 88 is rotatably connected to the locking drive shaft 6901 of the locking block 69, and the other end of the curved connecting plate 88 is rotatably connected to the connecting plate drive shaft 8901 of the dial 89. The turntable shaft 90 is rotatably mounted on the frame part J. A turntable flange 901 is installed at the front end of the turntable shaft 90, and a positioning plate 91 is installed at the rear end of the turntable shaft 90. Conical grooves that cooperate with the conical protrusions of the intermittent rotating arm 83 are evenly distributed on the outer circumference of the positioning plate 91. The quantitative camshaft 92 is rotatably mounted in the central hole of the turntable shaft 90. A quantitative cam 93 is mounted at the front end of the quantitative camshaft 92, and a cam groove is provided on the front end face of the quantitative cam 93. The rear end of the quantitative camshaft 92 is provided with a dial 89, a cam gear 95 and a planetary flange 96 in sequence. A dial gear 94 is provided on the rear end face of the dial 89. The planetary gear 97 is mounted on the planetary flange 96 through a planetary gear shaft 98. The planetary gear 97 meshes with the dial gear 94 and the cam gear 95 for transmission. The dial 89 is provided with a pawl drive shaft 8902, and the pawl 99 is rotatably mounted on the pawl drive shaft 8902. One end of the pawl 99 is provided with a right-angle protrusion, which cooperates with the stepped notch on the outer circumference of the positioning disk 91. The other end of the pawl 99 is provided with a spring hole, and a compression spring 100 and a compression spring post 101 are arranged in sequence in the spring hole. The compression spring post 101 abuts against the square stop post 102 mounted on the dial 89. The turntable 105 is mounted on the front end face of the turntable flange 901, and the turntable end plate 106 is mounted on the front end face of the turntable 105; the transmission fastening pin 104 is mounted on the dial 89 through the fastening pin mounting block 103, and the transmission fastening pin 104 is pressed against the outer circumference of the planetary flange 96.

[0062] The main motor 64 drives the sprocket cam 78 to rotate via the drive sprocket 66 and cam chain 80. The lifting cam 7802 and intermittent cam 7803 on the sprocket cam 78 drive the lifting arm 82 and intermittent arm 83 to move, respectively, realizing the lifting and swinging of the rounding part C and the intermittent positioning of the positioning plate 91. At the same time, the eccentric block 67 on the output shaft of the main motor 64 drives the cutting piston 76 to slide back and forth in the cutting chamber FQC via the connecting plate 68 and the arm 71, and drives the dial 89 to swing back and forth via the locking block 69 and the curved connecting plate 88. Only one main motor 64 is needed to realize the whole process of mechanical linkage of the reciprocating cutting of the cutting piston 76, the lifting and swinging of the rounding part C, and the intermittent rotation of the turntable 105. No multiple motors are required, the control is simple and the synchronization accuracy is high.

[0063] When the dial 89 reciprocates, it is driven by the planetary gear 97 meshing with the dial gear 94 and the cam gear 95 respectively. With the one-way locking action of the right-angle protrusion of the pawl 99 and the stepped notch on the outer circumference of the positioning plate 91, and the positioning engagement of the conical protrusion of the intermittent rotating arm 83 and the conical groove of the positioning plate 91, the quantitative cam 93 rotates 90° independently (at which time the turntable 105 is stationary). The cutting piston 76 advances for cutting, and the quantitative cam 93 and the turntable 105 rotate 90° in opposite directions synchronously (at which time the cutting piston 76 retracts). The turntable 105 drives each mold cavity component MQ to the next station. The two working conditions are precisely switched, and the three stations of quantitative cutting at station 1, rounding and shaping at station 2, and material pushing and unloading at station 3 are completed synchronously and in parallel.

[0064] For each revolution of the main motor 64, the quantitative cam 93 drives the actuating component BD through the cam groove on its front end to move the mold cavity adjusting block 114, so that the volume of the polygonal cavity LBKQ is constant. Under the drive of the eccentric block 67, the cutting piston 76 forcefully squeezes the dough into the polygonal cavity LBKQ of the mold cavity 113 with constant pressure, so as to realize the precise quantitative cutting of the dough according to the predetermined weight and achieve the consistency of the quality of each dough piece.

[0065] The intermittent rotary arm 83 oscillates periodically under the cooperation of the intermittent cam 7803 and the intermittent torsion spring 87. When the conical protrusion of the intermittent rotary arm 83 is embedded in the conical groove on the outer circumference of the positioning disk 91, the turntable 105 is locked and stationary. At this time, the quantitative cam 93 rotates 90° independently for cutting. When the conical protrusion disengages from the conical groove, the dial 89 pushes the positioning disk 91 to rotate through the pawl 99, and the turntable 105 rotates 90° synchronously to switch work positions. The conical groove ensures that the angle of each rotation of the turntable 105 is accurate, avoids the accumulation of inertial error, and achieves the docking accuracy of each work position.

[0066] The slitting section F integrates the main motor 64, eccentric block 67, sprocket cam 78, dial 89, planetary gear mechanism, pawl 99, turntable 105 and positioning plate 91 and other components on the base 63 of the frame section J. The turntable shaft 90 and the quantitative cam shaft 92 are installed in a coaxial nested manner, which has a high axial space utilization rate and a compact overall structure.

[0067] The working principle of the slitting part F of this invention is as follows: Initial position: such as Figure 13 As shown, turntable 105 is in the initial position, the mold cavity assembly MQ of station 1 is directly opposite the cutting chamber FQC, the mold cavity assembly MQ of station 2 is directly below the rounding mold 56 of the rounding section C, and the mold cavity assembly MQ of station 3 is directly opposite the conveyor belt 119 of the output section S.

[0068] Main motor start-up and power distribution: When the main motor 64 starts, its output shaft drives the drive sprocket 66 and the eccentric block 67 to rotate synchronously; the drive sprocket 66 drives the driven sprocket 7801 on the sprocket cam 78 through the cam chain 80, causing the sprocket cam 78 to rotate clockwise; the lifting cam 7802 and the intermittent cam 7803 on the sprocket cam 78 rotate accordingly; at the same time, the transmission shaft 6701 on the eccentric block 67 moves in a circular motion with the eccentric block 67.

[0069] The reciprocating motion of the cutting piston: The drive shaft 6701 of the eccentric block 67 drives the rocker arm shaft 72 to reciprocate on the rocker arm shaft seat 77 through the connecting plate 68, the short shaft 70 and the rotating arm 71. The rocker arm shaft 72 drives the rocker arm 73 to swing. The rocker arm 73 drives the cutting piston 76 to slide back and forth in the U-shaped structure of the cutting chamber FQC through the push bearing 74 and the push block 75. When the cutting piston 76 pushes to the left, it forcefully squeezes the dough into the polygonal cavity LBKQ of the mold cavity 113. When it retracts to the right, it prepares for the next cutting.

[0070] Asynchronous / synchronous switching rotation of turntable and quantitative cam: The drive shaft 6701 of eccentric block 67 drives dial 89 to reciprocate through locking block 69 and curved connecting plate 88; When the dial 89 swings clockwise, the right-angle protrusion of the pawl 99 is engaged in the stepped notch on the outer circumference of the positioning disk 91 under the action of the compression spring 100. At the same time, the transmission fastening pin 104 on the dial 89 drives the planetary gear 97 to revolve around the cam gear 95 through the planetary flange 96. Since the conical protrusion of the intermittent rotating arm 83 is embedded in the conical groove of the positioning disk 91 and locks the positioning disk 91, the turntable shaft 90 and the turntable 105 remain stationary. The quantitative cam shaft 92 rotates in the opposite direction through the meshing transmission of the cam gear 95 and the planetary gear 97, and the quantitative cam 93 rotates 90° independently. When the dial 89 swings counterclockwise, the right-angle protrusion of the pawl 99 compresses the compression spring 100 under the reverse push of the stepped notch of the positioning plate 91 and slides over the stepped notch. At the same time, the transmission fastener 104 drives the planetary gear 97 to revolve through the planetary flange 96. At this time, the conical protrusion of the intermittent rotating arm 83 is pushed away from the conical groove of the positioning plate 91 by the intermittent cam 7803, releasing the lock on the positioning plate 91. The turntable shaft 90 rotates 90° in the opposite direction synchronously with the quantitative cam shaft 92 under the drive of the planetary gear 97, and the turntable 105 rotates 90° accordingly.

[0071] One working cycle of the main motor: For each revolution of the main motor 64, the metering cam 93 rotates 90° clockwise (during which the turntable 105 remains stationary), and the cutting piston 76 moves to the left. Then, the metering cam 93 and the turntable 105 rotate 90° counterclockwise in sync (during which the cutting piston 76 moves back to the right). Under the continuous drive of the main motor 64, the mold cavity components MQ on the turntable 105 sequentially cycle into station 1, station 2 and station 3.

[0072] Three stations operate synchronously in parallel: When the quantitative cam 93 rotates, the cam groove on its front end drives the actuation bearing 109 on the large actuation arm 108 of each set of actuation components BD to move along the cam groove. The large actuation arm 108 drives the actuation shaft 107 to rotate. The small actuation arm 110 on the actuation shaft 107 drives the actuation roller 111 to swing. The actuation roller 111 abuts against the quantitative arc surface of the mold cavity adjustment block 114, so that the volume of the polygonal cavity LBKQ is constant. The mold cavity component MQ of station 1 cooperates with the cutting piston 76 to complete the quantitative cutting. The mold cavity component MQ of station 2 cooperates with the rounding mold 56 of the rounding part C to complete the rounding and shaping. When the actuation roller 111 pushes the mold cavity adjustment block 114, the mold cavity component MQ of station 3 pushes the rounded quantitative dough to the conveyor belt 119 of the output part S. The three stations operate synchronously in parallel to realize continuous production.

[0073] The actuation assembly BD includes an actuation shaft 107, a large actuation arm 108, an actuation bearing 109, a small actuation arm 110, an actuation roller 111, and an actuation roller shaft 112. The actuating shaft 107 is rotatably mounted on the turntable 105 and the turntable end plate 106. The rear end of the actuating shaft 107 extends out of the turntable 105 and is fixedly connected to one end of the large actuating arm 108. The other end of the large actuating arm 108 is equipped with an actuating bearing 109, which is embedded in the cam groove of the metering cam 93. The actuating shaft 107 is partially and spaced between the turntable 105 and the turntable end plate 106, with several small actuating arms 110 installed at intervals. The other end of each small actuating arm 110 passes through a roller shaft 112, and a roller 111 is rotatably mounted on the roller shaft 112. Multiple sets of the actuating components BD are evenly distributed along the circumference of the turntable 105.

[0074] The mold cavity assembly MQ includes a mold cavity 113, a mold cavity adjusting block 114, and a limiting pin 115; Multiple polygonal cavities LBKQ are arranged parallel to each other on the mold cavity 113. A mold cavity adjusting block 114 is slidably installed in each polygonal cavity LBKQ. The bottom end of the mold cavity adjusting block 114 is provided with a quantitative arc surface, which abuts against the roller 111 to keep the volume of the polygonal cavity LBKQ constant. Limiting pins 115 are provided on both sides of the bottom of the mold cavity adjusting block 114 to prevent the mold cavity adjusting block 114 from falling out of the polygonal cavity LBKQ. Multiple sets of mold cavity components MQ are evenly distributed along the circumference of the turntable 105, and each set of mold cavity components MQ is embedded in the corresponding notch of the turntable 105.

[0075] The bottom end of the mold cavity adjustment block 114 is provided with a quantitative arc surface, which abuts against the roller 111. When the roller 111 swings to the limit position where it abuts against the quantitative arc surface under the drive of the agitation component BD, the volume of the polygonal cavity LBKQ of the mold cavity 113 is limited to a constant value. The cutting piston 76 forcefully squeezes the dough into the polygonal cavity LBKQ with constant pressure. Excess dough is cut and squeezed high, so that the quality of the dough cut each time is accurate and consistent, avoiding the problem of low efficiency of traditional weighing methods.

[0076] The actuation bearings 109 of each set of actuation components BD are embedded in the cam groove of the quantitative cam 93. The multiple sets of actuation components BD, which are evenly distributed around the turntable 105, move synchronously with the rotation of the quantitative cam 93. There is no need to configure a separate drive device for each set of mold cavity components MQ. This realizes a compact design of single cam drive and multi-station linkage, reducing the number of power sources and transmission components.

[0077] The bottom sides of the mold cavity adjusting block 114 are provided with limiting pins 115. When the roller 111 swings away from the mold cavity 113, the limiting pins 115 are locked on the bottom end face of the mold cavity 113 to prevent the mold cavity adjusting block 114 from being pulled out of the polygonal cavity LBKQ by the roller 111. This ensures that the mold cavity adjusting block 114 always slides within the effective stroke, avoiding equipment failure and quantitative failure caused by the adjusting block coming off.

[0078] The quantitative arc surface at the bottom of the mold cavity adjusting block 114 is in line contact with the roller 111. The contact area is small and the frictional resistance is low. The roller 111 rotates on the roller shaft 112, which converts sliding friction into rolling friction, greatly reducing wear during the movement process and improving the service life and movement accuracy of the parts.

[0079] Each set of mold cavity components MQ is embedded in the corresponding notch of the turntable 105. The modular installation method allows for individual disassembly and replacement of a certain set of mold cavity components MQ when it is worn or needs to be replaced, without the need to replace the entire turntable 105, thus reducing maintenance costs. At the same time, different weight quantitative cutting can be achieved by replacing the mold cavity adjustment blocks 114 of different sizes, making it highly adaptable.

[0080] The working principle of the toggle component BD of this invention is as follows: Initial state: The quantitative cam 93 is at the initial angle, the actuating bearing 109 is embedded in a certain position in the cam groove of the front end face of the quantitative cam 93, the actuating rollers 111 of each set of actuating components BD respectively abut against the quantitative arc surface at the bottom end of the mold cavity adjusting block 114 of the corresponding mold cavity component MQ, and the polygonal cavity LBKQ is in the minimum volume state, that is, the volume corresponding to the set weight.

[0081] Quantitative cam drive stage (station 1 cutting): The main motor 64 operates, and the quantitative cam 93 rotates 90° clockwise (during this process, the turntable 105 is stationary). The cam groove on the front end face of the quantitative cam 93 rotates accordingly, and the contour curve of the cam groove pushes the embedded actuating bearing 109 to move along the cam groove trajectory. The actuating bearing 109 drives the large actuating arm 108 to swing around the actuating shaft 107. The large actuating arm 108 transmits the swing to the small actuating arm 110 located between the turntable 105 and the turntable end plate 106 through the actuating shaft 107. The small actuating arm 110 drives the actuating roller shaft 112 and the actuating roller 111 to swing. At this time, the actuating roller 111 of station 1 swings away from the mold cavity 113, causing the mold cavity adjusting block 114 to slide outward under its own weight and the extrusion force of the dough. As the volume of the polygonal cavity LBKQ gradually increases, the quantitative arc surface at the bottom of the mold cavity adjusting block 114 remains in contact with the roller 111 under the limit of the limiting pin 115. When the quantitative cam 93 rotates 90°, the roller 111 and the quantitative arc surface abut at the set position, and the volume of the polygonal cavity LBKQ is limited to a constant value. The cutting piston 76 simultaneously moves to the left, forcefully squeezing the dough into the polygonal cavity LBKQ to achieve quantitative cutting. At the same time, the roller 111 at station 2 keeps the rounded dough at the bottom of the mold cavity 113, and the roller 111 at station 3 swings towards the mold cavity 113, pushing the mold cavity adjusting block 114 to slide inward, pushing the rounded quantitative dough out of the polygonal cavity LBKQ to the output section S.

[0082] Synchronous rotation stage station switching: The main motor 64 continues to run, and the quantitative cam 93 and the turntable 105 rotate 90° in opposite directions synchronously (during this process, the cutting piston 76 retracts to the right). The quantitative cam 93 drives each set of actuating bearings 109 to move in opposite directions along the cam groove through the cam groove. The rollers 111 of each set of actuating components BD swing in opposite directions to prepare for the action of the next station. At the same time, the turntable 105 drives each set of actuating components BD and the mold cavity components MQ to rotate 90° as a whole, so that each mold cavity component MQ enters the next station in sequence.

[0083] Cyclic operation: The main motor 64 runs continuously, and the quantitative cam 93 periodically rotates 90° clockwise (turntable 105 is stationary) and rotates 90° counterclockwise synchronously with the turntable 105. When the turntable 105 rotates, each set of actuating components BD alternately executes the reciprocating oscillating action of the actuating roller 111 under the above two working conditions. This, combined with the reciprocating motion of the cutting piston 76 and the rounding action of the rounding part C, enables the mold cavity component MQ of station 1 to complete quantitative cutting, the mold cavity component MQ of station 2 to complete rounding and shaping, and the mold cavity component MQ of station 3 to complete material pushing and unloading. The three are synchronized and parallel, realizing continuous cyclic production.

[0084] The slitting chamber FQC includes a slitting base plate 116, slitting side plates 117, and a sealing arc plate 118. The slitting base plate 116 has slitting side plates 117 installed on its front and rear sides, forming a U-shaped structure. The slitting piston 76 is slidably installed within this U-shaped structure. The sealing arc plate 118 is installed on the left side of the slitting base plate 116. The sealing arc plate 118 has an arc surface that mates with the turntable 105 and a rectangular frame through which the slitting piston 76 passes. The slitting chamber FQC is installed on one side of the turntable 105 and is sealed to fit against the bottom notch of the hopper section L.

[0085] The rounding section C includes a rounding base 45, a pulley support sleeve 46, a rounding motor 47, a drive pulley 48, a transmission belt 49, a longitudinal guide shaft 50, a longitudinal sliding seat 51, a transverse guide shaft 52, a kneading sliding seat 54, a rounding seat 55, a rounding mold 56, an eccentric shaft 57, and a lifting rod 59. The rounding base 45 is mounted on the frame J. A rotating seat 4501 is mounted on the rounding base 45, and the pulley support sleeve 46 is rotatably mounted on the rotating seat 4501. The rounding motor 47 is mounted on the rounding base 45, and the output shaft of the rounding motor 47 is connected to the drive pulley 48 via a key. The drive pulley 48 and the pulley support sleeve 46 are connected by a transmission belt 49. The longitudinal guide shaft 50 is mounted on the rounding base 45, and the longitudinal sliding seat 51 is slidably mounted on the longitudinal guide shaft 50. The transverse guide shaft 52 is mounted on the longitudinal sliding seat 51, and the transverse guide shaft 52 is perpendicular to the longitudinal guide shaft 50. An anti-detachment baffle 53 is provided at the end of the transverse guide shaft 52; the kneading sliding seat 54 is slidably mounted on the transverse guide shaft 52, and the center of the kneading sliding seat 54 is provided with a central hole; the rounding seat 55 is installed below the kneading sliding seat 54, and the rounding mold 56 is installed on the rounding seat 55; the eccentric shaft 57 is fixedly installed in the shaft hole of the pulley support sleeve 46, and the lower end of the eccentric shaft 57 is provided with an eccentric shaft section, which is rotatably connected to the center hole of the kneading sliding seat 54 through a bearing; the lifting rod 59 is installed on one side of the rounding base 45, and the lower end face of the lifting rod 59 abuts against the second lifting bearing 85 of the cutting part F.

[0086] An eccentric shaft 57 is fixedly installed in the central hole of the pulley support sleeve 46. The lower end of the eccentric shaft 57 is provided with an eccentric shaft section, which is rotatably connected to the central hole of the kneading sliding seat 54 through a bearing. When the pulley support sleeve 46 rotates, the eccentric shaft section at the lower end of the eccentric shaft 57 makes a circular motion, which drives the kneading sliding seat 54 to make a compound circular motion in a two-dimensional plane on the longitudinal guide shaft 50 and the transverse guide shaft 52. The rounding mold 56 installed on the rounding seat 55 then makes a circular kneading action in the polygonal cavity LBKQ of the mold cavity assembly MQ, so that the dough is subjected to uniform and multi-directional kneading force in the polygonal cavity LBKQ, ensuring that the rounded dough has a regular shape and a smooth surface.

[0087] The rounding motor 47 transmits power to the pulley support sleeve 46 through the drive pulley 48 and the transmission belt 49. The belt drive has a buffering and vibration absorption effect, runs smoothly and has low noise, and avoids the impact and vibration that may be generated by gear transmission. This achieves the smoothness of the rounding action of the rounding mold 56 and the stability of the dough rounding quality.

[0088] The longitudinal guide shaft 50 is mounted on the rounding base 45, and the longitudinal sliding seat 51 is slidably mounted on the longitudinal guide shaft 50 to achieve sliding in the front-to-back direction; the transverse guide shaft 52 is mounted on the longitudinal sliding seat 51, and the transverse guide shaft 52 is perpendicular to the longitudinal guide shaft 50; the kneading sliding seat 54 is slidably mounted on the transverse guide shaft 52 to achieve sliding in the left-to-right direction; the longitudinal sliding and the transverse sliding are independent of each other and do not interfere with each other, accurately synthesizing the circular motion trajectory in the plane, thus achieving the accuracy of the rounding action.

[0089] The lifting rod 59 is installed on one side of the rounding base 45. The lower end face of the lifting rod 59 abuts against the second lifting bearing 85 of the cutting part F. When the lifting cam 7802 of the cutting part F drives the lifting arm 82 to swing, the second lifting bearing 85 pushes the lifting rod 59 to move up and down, realizing the lifting of the entire rounding base 45. When the turntable 105 rotates to switch positions, the lifting rod 59 is lifted, and the rounding mold 56 is lifted simultaneously to avoid the mold cavity assembly MQ. After the turntable 105 stops rotating, the lifting rod 59 falls, and the rounding mold 56 falls into the polygonal cavity LBKQ of the mold cavity assembly MQ for rounding. The timing is precise, avoiding interference and collision between the mold and the turntable 105.

[0090] The end of the transverse guide shaft 52 is provided with an anti-detachment baffle 53, which effectively prevents the kneading sliding seat 54 from detaching from the end of the transverse guide shaft 52 during high-speed circular motion, thus ensuring the safety and reliability of the equipment operation.

[0091] The working principle of the rounding part C of this invention is as follows: Initial state: A set of mold cavity components MQ on turntable 105 rotates to station 2, i.e., the rounding station. The polygonal cavity LBKQ of the mold cavity component MQ is already filled with a quantitatively divided dough. The rounding base 45 is in the lowered position. The rounding mold 56 extends into the polygonal cavity LBKQ of the mold cavity component MQ, contacts the dough but has not yet applied kneading force.

[0092] Rounding motor drive: When the rounding motor 47 is started, its output shaft drives the drive pulley 48 to rotate through a key connection. The drive pulley 48 drives the pulley support sleeve 46 to rotate on the rotating seat 4501 through the transmission belt 49.

[0093] Planar circular motion generation: When the pulley support sleeve 46 rotates, the eccentric shaft 57, which is fixedly installed in its central hole, rotates accordingly. The eccentric shaft segment at the lower end of the eccentric shaft 57 performs circular motion around the axis of the pulley support sleeve 46. This eccentric shaft segment is rotatably connected to the central hole of the kneading sliding seat 54 through a bearing, transmitting the circular motion to the kneading sliding seat 54. Under the constraint of the longitudinal guide shaft 50 and the transverse guide shaft 52, the kneading sliding seat 54 decomposes the circular motion of the eccentric shaft segment into reciprocating sliding along the longitudinal guide shaft 50 and reciprocating sliding along the transverse guide shaft 52, which combine to form a planar circular motion.

[0094] Rounding action: The rounding seat 55 is installed below the kneading slide seat 54, and the rounding mold 56 is installed on the rounding seat 55. Therefore, the rounding mold 56 follows the kneading slide seat 54 to make a synchronous planar circular motion. The rounding mold 56 makes a circular kneading action in the polygonal cavity LBKQ, applying a uniform and multi-directional kneading force to the dough in the cavity. The dough is continuously rolled and kneaded between the cavity wall of the polygonal cavity LBKQ and the rounding mold 56, and is gradually shaped into a sphere. After rounding is completed, the rounded dough falls to the bottom of the mold cavity assembly MQ under its own gravity.

[0095] Lifting sequence coordination: When the main motor 64 drives the sprocket cam 78 of the cutting section F to rotate, the lifting cam 7802 pushes the first lifting bearing 84 on the lifting arm 82, the lifting arm 82 swings, and the second lifting bearing 85 on it pushes the lifting rod 59 to move upward. The lifting rod 59 drives the entire rounding base 45 to swing upward around the rotating seat 4501. The rounding mold 56 is lifted from the polygonal cavity LBKQ in sync, providing clearance space for the turntable 105 to rotate and switch work positions. After the turntable 105 rotates 90°, the rounded dough is rotated to work position 3 with the mold cavity assembly MQ, and the new dough to be rounded is rotated from work position 1 to work position 2 with another set of mold cavity assemblies MQ. Then the lifting cam 7802 continues to rotate, and the lifting rod 59 descends under its own weight and the drive of the lifting cam 7802. The rounding mold 56 re-enters the new polygonal cavity LBKQ and begins the next round of rounding.

[0096] Continuous cycle: The rounding motor 47 keeps running continuously, and the rounding mold 56 continuously performs planar circular motion; under the periodic drive of the main motor 64, every time the turntable 105 rotates 90°, a new set of dough to be rounded enters station 2. The rounding mold 56 is periodically raised and lowered with the cooperation of the lifting rod 59, and the dough in each set of mold cavity component MQ entering station 2 is rounded and shaped, so as to realize the continuous rounding production of dough.

[0097] The frame section J includes a frame 60, a shock-absorbing column 61, a mounting base plate 62, and a base 63; the mounting base plate 62 is mounted on the frame 60 via the shock-absorbing column 61, and the base 63 is mounted on the mounting base plate 62; the output section S includes a conveyor belt 119, which is mounted on one side of the turntable 105 for receiving and conveying a fixed amount of dough after it has been rounded.

[0098] The working principle of the dough quantitative cutting and rounding integrated device of the present invention is as follows: I. Initial State Flour is placed into the first and second storage bins of the hopper section L, respectively. The large dough to be processed is placed above the V-shaped conveyor roller assembly formed by multiple conveyor roller shafts 5. The turntable 105 is in its initial position. The mold cavity assembly MQ of station 1 is directly opposite the cutting bin FQC. The mold cavity assembly MQ of station 2 is located directly below the rounding mold 56 of the rounding section C. The mold cavity assembly MQ of station 3 is directly opposite the conveyor belt 119 of the output section S.

[0099] II. Start-up of the entire machine Start the conveyor belt 119 to rotate counterclockwise; start the rounding motor 47, and through the transmission action of the drive pulley 48, transmission belt 49, pulley support sleeve 46 and eccentric shaft 57, make the rounding mold 56 installed on the rounding seat 55 continuously perform planar circular motion; start the main motor 64 to start the full-process mechanical linkage.

[0100] III. Main Motor Power Distribution After the main motor 64 starts, its output shaft drives the drive sprocket 66 and the eccentric block 67 to rotate synchronously. Sprocket cam drive circuit: The driving sprocket 66 drives the driven sprocket 7801 on the sprocket cam 78 through the cam chain 80, causing the sprocket cam 78 to rotate clockwise. The lifting cam 7802 and the intermittent cam 7803 on the sprocket cam 78 rotate accordingly, driving the lifting arm 82 and the intermittent arm 83 to swing periodically, realizing the lifting and swinging of the rounding part C and the intermittent positioning of the positioning plate 91; The slitting piston drive circuit is as follows: The drive shaft 6701 of the eccentric block 67 drives the rocker arm shaft 72 to swing back and forth through the connecting plate 68, the short shaft 70 and the rotating arm 71. The rocker arm shaft 72 drives the slitting piston 76 to slide back and forth in the slitting chamber FQC through the rocker arm 73, the push bearing 74 and the push block 75. Dial drive circuit: The drive shaft 6701 of the eccentric block 67 drives the dial 89 to reciprocate through the locking block 69 and the curved connecting plate 88.

[0101] IV. Material supply and dough conveying and cutting in the silo section When the cutter motor 12 starts, it drives the right cutter shaft 7 to rotate, and the right double-row sprocket 10 rotates accordingly. The first sprocket 1001 and the second sprocket 1002 drive the first chain 37 and the second chain 40 to rotate synchronously, respectively. The first chain 37 passes sequentially around the first sprocket 1001, the first transition wheel 38, the slow sprocket 17, the middle sprocket 18 and the fast sprocket 19 located on the right rear wall plate 3, the second transition wheel 39 and the third sprocket 1501, and transmits power to each conveying roller shaft 5 located on the right rear wall plate 3 and the left cutter shaft 6. The second chain 40 passes in sequence around the second sprocket 1002, the third transition wheel 41, the slow sprocket 17, the medium sprocket 18 and the fast sprocket 19 located on the left rear wall plate 2 side and the fourth sprocket 1502, and transmits power to each conveying roller shaft 5 located on the left rear wall plate 2 side and the right cutter shaft 7. At the same time, the brush motor 31 starts, driving the first brush 30 and the second brush 35 to rotate slowly. The large dough ball slides down above the V-shaped conveyor roller assembly under its own weight and the traction of the left and right conveyor rollers 8. The left conveyor rollers 8 rotate clockwise, and the right conveyor rollers 8 rotate counterclockwise. The three conveyor rollers 8 on the same side rotate at progressively increasing speeds from slow to fast under the drive of the slow sprocket 17, the medium sprocket 18 and the fast sprocket 19, forming a speed gradient and accelerating the downward slide of the dough ball.

[0102] During rotation, the V-shaped grooves on the left and right conveying rollers 8 evenly carry out the flour from the first and second flour storage bins and coat the surface of the dough. At the same time, the flour from the first and second flour storage bins is first carried by the first brush 30 to the top of the powder-splitting plate 24, then passes through the powder-splitting holes of the powder-splitting plate 24 and falls onto the second brush 35. Then, the second brush 35 is evenly sprinkled into the cutting bin FQC of the cutting section F by rotation, forming a double powder-sprinkling effect, which avoids the dough from sticking to the wall and sticking together in all directions.

[0103] After the dough is conveyed to the bottom, the cutter 9 on the left cutter shaft 6 and the cutter 9 on the right cutter shaft 7 rotate relative to each other under the drive of the cutter motor 12, continuously cutting the large dough into small pieces of dough. The cut pieces of dough fall into the cutting chamber FQC of the cutting section F. At the same time, a small amount of flour sprinkled on the second brush 35 covers the surface of the dough to prevent the dough from sticking together again during subsequent processing.

[0104] V. The three workstations in the slitting section operate synchronously and in parallel. Driven by the main motor 64, the slitting section F rotates asynchronously or synchronously with the turntable 105 via the quantitative cam 93. Each time a work cycle is completed, the turntable 105 rotates 90°, and the three sets of mold cavity components MQ synchronously execute different processes. (a) The quantitative cam rotates 90° independently (turntable 105 is stationary, and the cutting piston is advancing). When dial 89 swings clockwise, the right-angled protrusion of pawl 99, under the action of compression spring 100, engages in the stepped notch on the outer circumference of positioning disk 91. At this time, the conical protrusion of intermittent rotating arm 83 is embedded in the conical groove of positioning disk 91 to lock positioning disk 91. Turntable shaft 90 and turntable 105 remain stationary, metering cam shaft 92 rotates in the opposite direction, and metering cam 93 rotates 90° clockwise independently. Station 1 quantitative cutting: The cutting piston 76 moves to the left, and at the same time, the cam groove on the front end of the quantitative cam 93 drives the toggle assembly BD of station 1. The toggle roller 111 swings away from the mold cavity 113, the mold cavity adjustment block 114 slides outward, and the volume of the polygonal cavity LBKQ is limited to a constant value. The cutting piston 76 forcefully squeezes the dough in the cutting chamber FQC into the polygonal cavity LBKQ of the mold cavity 113, so as to achieve precise quantitative cutting of the dough according to the predetermined weight, and the excess dough is cut and squeezed high. Station 2 Rounding and Shaping: The rounding mold 56 performs a circular kneading action in the polygonal cavity LBKQ, applying a uniform and multi-directional kneading force to the dough in the cavity, causing the dough to continuously roll and knead between the cavity wall and the rounding mold 56, gradually being shaped into a spherical shape; Station 3 Material Pushing and Discharging: The roller 111 swings towards the mold cavity 113, pushing the mold cavity adjusting block 114 to slide inward, pushing the rounded quantitative dough out of the polygonal cavity LBKQ and dropping it onto the conveyor belt 119 to be transported to the next process.

[0105] (ii) The stage of synchronous 90° rotation of the quantitative cam and the turntable (when the cutting piston retracts) When the dial 89 swings counterclockwise, the right-angle protrusion of the pawl 99 slides over the stepped notch of the positioning plate 91. At this time, the conical protrusion of the intermittent rotating arm 83 is pushed away from the conical groove of the positioning plate 91 by the intermittent cam 7803, releasing the lock on the positioning plate 91. The turntable shaft 90 rotates 90° in the opposite direction synchronously with the quantitative cam shaft 92 under the drive of the planetary gear 97. The cutting piston 76 retracts to the right, and the turntable 105 rotates 90° accordingly. Each set of mold cavity components MQ enters the next station. At the same time, the lifting rod 59 is lifted, and the rounding mold 56 is lifted synchronously to avoid the mold cavity component MQ.

[0106] The main motor 64 runs continuously, and the above two stages are carried out alternately. The three workstations operate synchronously and in parallel to achieve continuous cyclic production.

[0107] VI. Coordination of the rising and falling sequence of the rounding section The lower end face of the lifting rod 59 abuts against the second lifting bearing 85 of the cutting section F. When the lifting cam 7802 of the cutting section F drives the lifting arm 82 to swing, the second lifting bearing 85 pushes the lifting rod 59 to move up and down, realizing the lifting and swinging of the entire rounding base 45 around the rotating seat 4501. When the turntable 105 rotates to switch work positions, the lifting rod 59 is lifted, and the rounding mold 56 is simultaneously lifted to avoid the mold cavity assembly MQ. After the turntable 105 stops rotating, the lifting rod 59 falls, and the rounding mold 56 falls into the new polygonal cavity LBKQ to perform rounding. The timing is precise, avoiding interference and collision between the mold and the turntable 105.

[0108] VII. Feedback Control and On-Demand Material Supply The photoelectric sensor 36, installed at the position corresponding to the front stop 27 and the hopper wall panel 1, detects in real time whether there is dough in the cutting chamber FQC: When the dough in the cutting chamber FQC is sufficient, the photoelectric sensor 36 continuously detects the signal. When the cutting piston 76 retracts to the right, the cutter motor 12 and the brush motor 31 do not start, and the feeding stops. When there is insufficient dough in the cutting chamber FQC, the photoelectric sensor 36 cannot detect a signal. When the cutting piston 76 retracts to the right, the cutter motor 12 and the brush motor 31 start a working cycle to replenish the dough to the cutting chamber FQC. This process is repeated continuously to achieve on-demand material supply and automatic start / stop control, avoiding idle running of the cutter 9 and ineffective cutting.

[0109] 8. Continuous Cycle Production The main motor 64 operates continuously, and the above actions are repeated: the material bin L continuously replenishes the small pieces of dough cut into the cutting bin FQC; the cutting piston 76 slides back and forth in the cutting bin FQC under the drive of the main motor 64; the turntable 105 rotates 90° after completing one work cycle under the drive of the main motor 64, driving each set of mold cavity components MQ to sequentially perform quantitative cutting, rounding and shaping and pushing out operations; the rounding mold 56 continuously performs planar circular motion, and with the cooperation of the lifting rod 59, rounds and shapes the dough in each set of mold cavity components MQ that enter station 2; the conveyor belt 119 operates continuously, transporting the rounded quantitative dough pushed out from station 3 to the next process.

[0110] Thus, this invention realizes fully automated continuous production from large dough balls to quantitative small dough balls and completes the rounding and shaping process.

[0111] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
