Description

Technical Field

[0001] This invention relates to the field of bread production technology, and in particular to an automatic weighing and shaping bread production line equipment and its working method. Background Technology

[0002] In the mass production of bread, weighing and shaping are two crucial steps. The general production process begins with cutting the dough into multiple pieces to make the bread. These pieces are then weighed to ensure they meet the weight requirements for the specific type of bread, preventing the dough from being too small or too large, which would result in bread of the correct size after baking. After weighing, the dough is then shaped to deflate it, adjusting its texture, strengthening its gluten, and promoting fermentation.

[0003] Traditional bread shaping and weighing typically rely on manual labor, which is inefficient. Summary of the Invention

[0004] To address the shortcomings mentioned above in the background technology, the present invention provides an automatic weighing and shaping bread production line equipment and its working method.

[0005] The present invention adopts the following technical solution:

[0006] In a first aspect, the present invention discloses an automatic weighing and shaping bread production line equipment, the equipment comprising:

[0007] A receiving tray for receiving the cut dough, and the receiving tray has a built-in weighing module for weighing the dough;

[0008] A guiding mechanism includes a guiding tunnel, a guiding seat, and a drive shaft. The inner wall of the guiding tunnel is recessed to form a guiding groove. The guiding groove includes a spiral groove and a first straight groove and a second straight groove connecting the two ends of the spiral groove. The spiral groove is located at the top of the inner wall of the guiding tunnel and spirals at 180°. The first straight groove and the second straight groove are respectively arranged on both sides of the guiding groove and are arranged parallel to each other. The guiding seat is disposed below the guiding tunnel and moves parallel to the straight extension direction of the first straight groove or the second straight groove. A connecting column is also provided below the guiding seat. The drive shaft passes through the guiding seat and is axially fixed relative to the guiding seat. One end of the drive shaft is fixed to the receiving plate, and a guide part is provided on the side of the other end of the drive shaft. The guide part is adapted to be embedded into the guiding groove.

[0009] A cutting mechanism is disposed below the guide tunnel. The cutting mechanism includes a first conveyor, a drive seat, a driven seat, a first connecting rod, a second connecting rod, a first limiting rod, a second limiting rod, and a cutter. The first conveyor is fixed below the guide tunnel. Two first limiting rods are pivotally connected above the first conveyor. Two second limiting rods are pivotally connected to the driven seat. Several sets of cross-pivoted first and second connecting rods are arranged between the drive seat and the driven seat. The two first limiting rods are pivotally connected to the first and second connecting rods at one end, and the second limiting rods are pivotally connected to the first and second connecting rods at the other end. In each set of cross-pivoted first and second connecting rods, the two ends of the first connecting rod are pivotally connected to the adjacent second connecting rods, and the two ends of the second connecting rod are pivotally connected to the adjacent first connecting rods. A cutter is also fixed at the bottom of the first or second connecting rod, and the cutter extends to the conveying surface of the first conveyor. The drive seat is restricted to move linearly along the conveying direction of the first conveyor.

[0010] When the guide seat moves, it drives the drive shaft and the receiving plate to move in the direction of the guide tunnel. The guide part moves along the guide groove, causing the receiving plate to flip so that the dough is poured onto the first conveyor. The connecting column pushes the drive seat to move.

[0011] In one possible implementation of the first aspect, the device further includes a drive mechanism comprising a drive motor, a first swing arm, and a second swing arm. The drive motor is fixed below the guide tunnel, and the output shaft of the drive motor is fixedly connected to one end of the first swing arm. The two ends of the second swing arm are respectively pivotally connected to one end of the first swing arm and the connecting column.

[0012] In one possible implementation of the first aspect, the guide portion is connected to a roller, which is adapted to rotate within the guide groove.

[0013] In one possible implementation of the first aspect, the guiding mechanism further includes a connecting frame, the guiding tunnel is fixed to the connecting frame, and two first gantry frames are fixed under the connecting frame, both of which are fixed to the first conveyor.

[0014] In one possible implementation of the first aspect, slide rails are fixed on both sides of the connecting frame, and both slide rails are adapted to connect sliders. The two sides of the guide seat are respectively fixed to the sliders of the two slide rails.

[0015] In one possible implementation of the first aspect, a connecting frame is fixed at the front end of the guide tunnel, on which a push plate is provided. The push plate is positioned above the receiving plate when it is flipped to the horizontal position, and the push plate moves relative to the receiving plate.

[0016] In one possible implementation of the first aspect, a pusher is provided below the connecting post, and the pusher and the connecting post are connected by a first spring. A first guide surface is provided above the side of the drive seat facing the connecting post. When the connecting post abuts against the first guide surface and pushes the drive seat to move until the drive seat is locked, the pusher moves upward along the first guide surface to above the drive seat and continues to move and compress the first spring.

[0017] In one possible implementation of the first aspect, a receiving hole is formed inside the lower end of the connecting post, and a strip-shaped hole penetrating both sides is also provided at the lower end of the connecting post. The strip-shaped hole is vertically arranged and communicates with the receiving hole. A connecting pin is fixed on the pushing member. A limiting pin is fixed on the side of the connecting pin. The first spring and the connecting pin are both embedded in the receiving hole. The limiting pin passes through the strip-shaped hole, so that the first spring pushes the connecting pin downward until the limiting pin abuts against the lower end of the strip-shaped hole.

[0018] In one possible implementation of the first aspect, a second spring is fixed to the side of the driven seat facing away from the drive seat, and a first gantry is fixed to the first conveyor. When the drive seat moves to the point where it is jammed, the driven seat moves to compress the second spring against the first gantry.

[0019] Secondly, the present invention also provides a method for operating the above-mentioned device, the method of which is as follows:

[0020] The dough is placed on the receiving tray, which weighs the dough. If the weight is within acceptable limits, the guide seat moves to rotate the drive shaft. As the drive shaft rotates, it drives the receiving tray to rotate, so that the dough is poured into the first conveyor. This allows the first conveyor to continuously transport the dough to the end away from the receiving tray.

[0021] The movement of the guide seat causes the connecting column to push the drive seat to move, thereby causing the first and second connecting rods of each set of cross components to swing toward the first conveyor, causing each cutter to swing toward the end point of the first conveyor and toward the middle of the first conveyor, forming an action of cutting the dough located on the first conveyor.

[0022] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: The present invention uses the movement of the guide seat to rotate the drive shaft, which in turn drives the receiving plate to rotate, allowing the weighed dough to be poured onto the first conveyor for conveying. Simultaneously, the movement of the guide seat causes the connecting shaft to push the drive seat to move, causing the first and second connecting rods of each cross component to swing, thus realizing the cutting action of the cutter. In other words, the present invention can achieve the pouring of automatically weighed dough into the first conveyor simply by moving the guide seat, while simultaneously driving the first and second connecting rods to swing and cut the dough. Therefore, the present invention can achieve automatic weighing of continuous dough, and also continuously cut both sides of the weighed dough to expose the inside of the dough, thereby expelling the air inside the dough and completing the automatic degassing work in dough shaping. All of the above work requires no manual operation and can achieve continuous automatic weighing and degassing, which is beneficial to improving the efficiency of bread making, thereby increasing production efficiency.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0040] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0041] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0042] This invention provides an automated weighing and shaping bread production line equipment and its working method, as shown in the attached figure. Figures 1 to 6 As shown, the device includes a receiving tray 1, a guiding mechanism 2, a cutting mechanism 3, and a driving mechanism 4. The driving mechanism 4 drives the guiding mechanism 2 and the cutting mechanism 3, causing the guiding mechanism 2 to move the receiving tray 1 linearly and rotate. After the receiving tray 1 receives and weighs the dough, it is flipped to pour the qualified dough downwards into the cutting mechanism 3 for cutting, degassing, and shaping. Preferably, the device of the present invention can also be equipped with a control system, which receives the weight signal sensed by the receiving tray 1 and controls the operation of the driving device.

[0043] The receiving tray 1 has a built-in weighing module for weighing dough. The weighing module can be a gravity sensor. When the receiving tray 1 receives the cut dough, the weighing module converts the weight of the dough into an electrical signal, and then the control system detects whether the weight of the dough is within the qualified weight value.

[0044] As attached Figures 7 to 9 As shown, the guiding mechanism 2 includes a guiding tunnel 21, a guiding seat 22, and a drive shaft 23. The inner wall of the guiding tunnel 21 is recessed to form a guiding groove 211. The guiding groove 211 includes a spiral groove 2113 and a first straight groove 2111 and a second straight groove 2112 connecting the two ends of the spiral groove 2113. The spiral groove 2113 is located at the top of the inner wall of the guiding tunnel 21 and spirals at 180°. The first straight groove 2111 and the second straight groove 2112 are respectively arranged on both sides of the guiding groove 211, and the first straight groove 2111 and the second straight groove 2112 are parallel to each other and horizontally arranged. (See attached diagram.) Figure 4 The guide mechanism 2 also includes a connecting frame 24. The guide tunnel 21 is fixed to the connecting frame 24. The guide seat 22 is disposed inside the connecting frame 24. Slide rails 251 are fixed on both sides inside the connecting frame 24. The slide rails 251 are parallel to the first straight groove 2111 and the second straight groove 2112. Both slide rails 251 are adapted to connect sliders 252. The two sides of the guide seat 22 are respectively fixed to the sliders 252 of the two slide rails 251, thereby restricting the guide seat 22 to move parallel to the straight extension direction of the first straight groove 2111 or the second straight groove 2112 when it is located under the guide tunnel 21.

[0045] As attached Figure 8 As shown, a connecting post 221 is also provided below the guide seat 22. See also the attached diagram. Figure 10 The drive mechanism 4 includes a drive motor 43, a first swing arm 41, and a second swing arm 42. The drive motor 43 is fixed below the guide tunnel 21, and its output shaft is fixedly connected to one end of the first swing arm 41. The two ends of the second swing arm 42 are pivotally connected to one end of the first swing arm 41 and the connecting post 221, respectively. In this structure, when the drive motor 43 drives the first swing arm 41 to rotate, it can pull or push the second swing arm 42 to move accordingly, thereby driving the guide seat 22 to move. This achieves the goal of moving the guide seat 22 through the drive motor 43.

[0046] As attached Figures 7 to 9As shown, the drive shaft 23 passes through the guide seat 22, and the axial direction of the drive shaft 23 is fixed relative to the guide seat 22. Simultaneously, the axis of the drive shaft 23 is coaxial with the axis of the helix of the helical groove 2113. Specifically, the drive shaft 23 and the guide seat 22 can be connected by mounting bearings at both ends of the guide seat 22. After the drive shaft 23 passes through the inner rings of the two bearings, snap rings are fitted onto the edge of the side of the drive shaft 23 facing the middle of the guide seat 22. These snap rings then block the two bearings, preventing the drive shaft 23 from moving relative to the guide seat 22 and fixing it axially. The drive shaft 23 can only rotate relative to the guide seat 22. Additionally, one end of the drive shaft 23 is fixed to the receiving plate 1, allowing the receiving plate 1 to rotate when the drive shaft 23 rotates. The other end of the drive shaft 23 has a guide portion 231 on its side, which is fitted into the guide groove 211 and moves along the guide groove 211. When the guide seat 22 moves and drives the drive shaft 23 and the receiving plate 1 to move in the direction of the guided tunnel 21, the guide part 231 moves along the guide groove 211, forming a movement process from the first straight groove 2111 through the spiral groove 2113 to the second straight groove 2112. This process drives the drive shaft 23 to rotate, causing the receiving plate 1 to flip and pour the dough onto the cutting mechanism 3. Preferably, the guide part 231 is connected to a roller, which is adapted to be embedded in the guide groove 211 to rotate, so as to reduce the friction of the guide part 231 moving in the guide groove 211, thereby improving the smoothness of the guide shaft operation.

[0047] As attached Figures 13 to 16 As shown, the cutting mechanism 3 includes a first conveyor 31, a drive seat 32, a driven seat 33, a first connecting rod 34, a second connecting rod 35, a first limiting rod 36, a second limiting rod 37, and a cutter 38. (See attached diagram) Figure 14 As shown, the drive seat 32 is provided with an elongated limiting hole 321 along the conveying direction of the first conveyor 31. A second gantry 391 is fixed above the first conveyor 31. The second gantry 391 has upwardly protruding limiting posts 392 fixed at both ends of the first conveyor 31. Both limiting posts 392 are adapted to pass through the limiting hole 321, so that the drive seat 32 is restricted to move linearly along the conveying direction of the first conveyor 31. Two first gantry 241s are fixed under the connecting frame 24 of the guide mechanism 2. Both first gantry 241s are fixed on the first conveyor 31 so that the first conveyor 31 is fixed below the guide tunnel 21, and the guide tunnel 21 is located above the cutting mechanism 3. Two first limiting rods 36 are pivotally connected above the first conveyor 31. The pivotal connection is as follows: a rotating shaft is fixed on the second gantry 391, and one end of the two first limiting rods 36 is stacked and sleeved on the rotating shaft to form a pivot connection. Furthermore, a retaining ring is installed on the first limiting rod 36 located above the rotating shaft to restrict the ends of the two first limiting rods 36 to the rotating shaft.

[0048] Driven seat 33 is pivotally connected to two second limiting rods 37, and one end of each second limiting rod 37 within driven seat 33 is fixed with a gear (not shown in the attached figure). The two gears mesh with each other, causing the two second limiting rods 37 to swing synchronously and in opposite directions relative to driven seat 33. A series of cross-connected first connecting rods 34 and second connecting rods 35 are arranged between drive seat 32 and driven seat 33. In each cross-connected assembly, the two first limiting rods 36 are pivotally connected to the first connecting rod 34 and second connecting rod 35 in the cross-connected assembly at one end, and the second limiting rods 37 are pivotally connected to the first connecting rod 34 and second connecting rod 35 in the cross-connected assembly at the other end. The middle position of the intersection of the first connecting rod 34 and second connecting rod 35 in the cross-connected assembly at the other end is pivotally connected to drive seat 32. Simultaneously, in each cross-connected assembly, both ends of the first connecting rod 34 are pivotally connected to the second connecting rod 35 of the adjacent cross-connected assembly, and both ends of the second connecting rod 35 are pivotally connected to the first connecting rod 34 of the adjacent cross-connected assembly. A cutter 38 is also fixed to the bottom of the first link 34 or the second link 35, and the cutter 38 extends to the conveying surface of the first conveyor 31. With the above structure, when the guide seat 22 moves and the connecting column 221 moves accordingly, the connecting column 221 pushes the drive seat 32 to move. When the drive seat 32 moves, it drives the first link 34 and the second link 35, which are pivotally connected to the drive seat 32, to swing in a direction parallel to the length of the first conveyor 31. This causes the first link 34 and the second link 35 of each set of cross components to swing in sequence, so that each cutter 38 swings forward synchronously and toward the middle of the first conveyor 31 to form a cutting action, thereby cutting the dough being conveyed on the first conveyor 31.

[0049] Please refer to the appendix. Figure 16 Two second gantry frames 391 are fixed on the first conveyor 31. The two second gantry frames are connected to the second conveyor 39 below. The second conveyor 39 is located above the first conveyor 31, so that each cutter 38 is positioned between the first conveyor 31 and the second conveyor 39. The conveyor belts of the first conveyor 31 and the second conveyor 39 run at the same speed. The lower surface of the conveyor belt of the second conveyor 39 and the upper surface of the conveyor belt of the first conveyor 31 run in the same direction. Specifically, [details omitted]. Figure 1 and 6 The direction is shown from right to left. When the dough is conveyed between the first conveyor 31 and the second conveyor 39, the conveyor belts of the first conveyor 31 and the second conveyor 39 can form a state that clamps and conveys the dough, preventing the cutter 38 from failing to cut through the side of the dough. Preferably, inclined guide plates 393 are fixed on both sides of the first conveyor 31 before entering the second conveyor 39. Both guide plates 393 are inclined towards the middle of the first conveyor 31, so that the dough conveyed between the first conveyor 31 and the second conveyor 39 can be guided by the two guide plates 393 to the middle of the first conveyor 31 for conveying.

[0050] As attached Figure 11 and 12 As shown, a pusher 44 is provided below the connecting column 221. The pusher 44 and the connecting column 221 are connected by a first spring 45. A first guide surface is provided above the side of the drive seat 32 facing the connecting column 221. When the connecting column 221 pushes the drive seat 32 against the first guide surface and moves it until the drive seat 32 is locked, the pusher 44 moves upward along the first guide surface above the drive seat 32 and continues to move, compressing the first spring 45. Compared with the method where the connecting column 221 is directly connected to the drive seat 32 and drives the drive seat 32 to move, this structure can shorten the stroke of the connecting column 221 pushing the drive seat 32 to move, thereby reducing the overall length of the cutting mechanism 3. This avoids the cutting mechanism 3 extending into the space above the end of the first conveyor 31 away from the receiving plate 1 after being stretched, making it difficult for workers to pick up the shaped dough in that space.

[0051] Please refer to the appendix. Figure 4 A receiving hole is formed inside the lower end of the connecting post 221. A strip-shaped hole 222 penetrating both sides is also provided on the side of the connecting post 221. The strip-shaped hole 222 is vertically oriented and communicates with the receiving hole. A connecting pin is fixed on the pushing member 44. A limiting pin 46 is fixed to the side of the connecting pin; preferably, the limiting pin 46 can be a bolt. During assembly, the first spring 45 and the connecting pin are sequentially inserted into the receiving hole. Then, the limiting pin 46 is threaded through the strip-shaped hole 222 and screwed onto the connecting pin. The limiting pin 46 restricts the connecting pin to move vertically relative to the connecting post 221 only along the strip-shaped hole 222. The elastic force of the first spring 45 pushes the connecting pin downwards until the limiting pin 46 abuts against the lower end of the strip-shaped hole 222. When the guide seat 22 moves, pushing the connecting post 221 towards the drive seat 32, the pushing member 44 moves upwards along the first guide surface above the drive seat 32 and continues to move, compressing the first spring 45.

[0052] Please refer to the appendix. Figure 13 and 16 A second spring 331 is fixed to the side of the driven seat 33 facing away from the drive seat 32. A first gantry frame 241 is fixed to the first conveyor 31. When the connecting column 221 pushes the drive seat 32 to move until the drive seat 32 is locked, the driven seat 33 moves to compress the second spring 331 against the first gantry frame 241. The state in which the drive seat 32 is locked can be that the end of the drive seat 32 away from the connecting rod 34 and the second connecting rod 35 is against the rotating shaft and cannot move further; or it can be as shown in the attached diagram. Figure 16One end of the driven seat 33 is pressed against the first gantry 241, preventing the cross-assemblies from swinging further, thus preventing the drive seat 32 from moving further. When the drive seat 32 can no longer move, the pusher 44 compresses the first spring 45 and moves upward. The pusher 44 and the connecting column 221 can no longer block the drive seat 32 and therefore cannot block the second spring 331. At this time, the elastic force of the second spring 331 pushes the driven seat 33 to move towards the drive seat 32, causing the two second limit rods 37 to swing outward to both sides of the driven seat 33. This causes the first connecting rod 34 and the second connecting rod 35 in each cross-assembly to swing in a direction that is flush with the width of the first conveyor 31. This causes the first connecting rod 34 and the second connecting rod 35 of each cross-assembly to swing in turn, so that each cutter 38 swings backward and to both sides of the first conveyor 31 in sync, forming a cutting action, thereby cutting the dough being conveyed on the first conveyor 31.

[0053] The aforementioned cutter 38 performs a cutting action to cut the dough conveyed on the first conveyor 31, exposing the interior of the dough and thus expelling air from inside. A rotatable pressure roller 310 is also provided near the end of the first conveyor 31. The pressure roller 310 is arranged laterally relative to the first conveyor 31, and there is a gap between the pressure roller 310 and the upper surface of the conveyor belt of the first conveyor 31. When the dough is cut by the cutters 38 and passes under the pressure roller 310, the pressure roller 310 rotates accordingly, compacting the cut dough.

[0054] In addition, see attached Figure 1 and 6As shown, the device of the present invention also includes a sorting mechanism 5, which includes a drive cylinder 53 and a pusher plate 51. The drive cylinder 53 is an actuator such as a cylinder, hydraulic cylinder, or electric pusher with a piston rod in the prior art, and the control system controls the operation of the drive cylinder 53. The drive cylinder 53 is fixed at an angle above the receiving plate 1. Specifically, a third gantry frame can be fixed above the connecting frame 24, and the drive cylinder 53 is fixed on the third gantry frame to avoid the movement space of the receiving plate 1. The pusher plate 51 is fixed to the end of the piston rod of the drive cylinder 53. When the weight of the dough weighed by the receiving plate is unqualified, the control system controls the piston rod of the drive cylinder 53 to extend so that the pusher plate 51 pushes the dough on the receiving plate 1 directly out of the receiving plate 1, and slides down the hopper 54 fixed to the starting end of the first conveyor 31. Preferably, a frame (not shown in the figure) can also be placed at the lower end of the hopper 54 to receive the dough with unqualified weight. Furthermore, the sorting mechanism 5 also includes a telescopic plate 52. Limiting grooves 511 are provided on both sides of the front of the push plate 51. The telescopic plate 52 is fitted into the two limiting grooves 511 on both sides, allowing the telescopic plate 52 to telescopically move relative to the push plate 51. Blocking parts 521 are fixed on both sides of the upper part of the telescopic plate. These blocking parts 521 prevent the telescopic plate 52 from falling off the push plate 51. When the push plate 51 moves downwards onto the receiving tray 1, the telescopic plate 52 moves to abut against the surface of the receiving tray 1. As the piston rod extends, the telescopic plate 52 rises relative to the receiving tray while simultaneously moving forward parallel to it, preventing the push plate 51 from moving downwards and getting stuck in the middle of the receiving tray 1, thus preventing the dough from being pushed out of the receiving tray 1. Furthermore, pulleys 522 are provided on both sides of the lower end of the telescopic plate 52 to improve the smoothness of its parallel movement on the receiving tray 1.

[0055] Secondly, the present invention also discloses the working method of the above-mentioned device, which is as follows:

[0056] The dough is placed on the receiving tray 1, and the receiving tray 1 weighs the dough. If the weight is not up to standard, the push plate 51 pushes the dough off the front end of the receiving tray 1. If the weight is up to standard, the control system controls the drive motor 43 to drive the guide seat 22 to move, thereby causing the drive shaft 23 to rotate. As the drive shaft 23 rotates, it drives the receiving tray 1 to rotate, so that the dough is poured into the first conveyor 31. This allows the first conveyor 31 to continuously transport the dough to the end away from the receiving tray 1.

[0057] The guide seat 22 moves, causing the connecting column 221 to push the drive seat 32 to move, thereby driving the first link 34 and the second link 35 of each group of cross components to swing in a direction aligned with the length of the first conveyor 31, causing each cutter 38 to swing toward the end point of the first conveyor 31 and toward the middle of the first conveyor 31, forming an action of cutting the dough located on the first conveyor 31.

[0058] When the drive seat 32 moves toward the end of the first conveyor 31 and gets stuck, the driven seat 33 moves to compress the second spring 331 against the first gantry 241, and causes the pusher 44 to move upward and compress the first spring 45, so that the pusher 44 and the connecting column 221 can no longer block the drive seat 32 and therefore cannot block the second spring 331. The elastic force of the second spring 331 returning to its original tension pushes the driven seat 33 toward the beginning of the first conveyor, causing the first link 34 and the second link 35 in each set of cross assemblies to swing in a direction aligned with the width of the first conveyor 31, causing each cutter 38 to swing toward the beginning of the first conveyor 31 and toward both sides of the first conveyor 31 to form a cutting action, thereby cutting the dough being conveyed on the first conveyor 31 again.

[0059] As can be seen from the above working method, the present invention uses the movement of the guide seat 22 to rotate the drive shaft 23, which in turn drives the receiving plate 1 to rotate so that the weighed dough is poured onto the first conveyor 31 for conveying. At the same time, the movement of the guide seat 22 causes the connecting shaft to push the drive seat 32 to move, which in turn causes the first connecting rod 34 and the second connecting rod 35 of each cross component to swing, thereby realizing the cutting action of the cutter 38. In other words, the present invention can realize the pouring of automatically weighed dough into the first conveyor 31 by the movement of the guide seat 22, and at the same time drive the first connecting rod 34 and the second connecting rod 35 to swing and cut the dough. It can be seen that the present invention can realize the automatic weighing of continuous dough, and at the same time, it can continuously cut both sides of the weighed dough to expose the inside of the dough, thereby expelling the air inside the dough and completing the automatic degassing work in dough shaping.

[0060] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.

7. The device as described in claim 6, characterized in that, A pusher is provided below the connecting column, and the pusher and the connecting column are connected by a first spring. A first guide surface is provided above the side of the drive seat facing the connecting column. When the connecting column abuts against the first guide surface and pushes the drive seat to move until the drive seat is stuck, the pusher moves upward along the first guide surface to above the drive seat and continues to move and compress the first spring.

8. The device as described in claim 7, characterized in that, The lower end of the connecting post has a receiving hole, and the lower end of the connecting post also has a strip hole that runs through both sides. The strip hole is vertically arranged and communicates with the receiving hole. A connecting pin is fixed on the pushing member. A limiting pin is fixed on the side of the connecting pin. The first spring and the connecting pin are both embedded in the receiving hole. The limiting pin passes through the strip hole, so that the first spring pushes the connecting pin downward until the limiting pin abuts against the lower end of the strip hole.

9. The device as described in claim 1, characterized in that, A second spring is fixed to the side of the driven seat facing away from the driving seat. A first gantry frame is fixed on the first conveyor. When the driving seat moves to the point where it is stuck, the driven seat moves to compress the second spring against the first gantry frame.

10. A method of operating the device as described in any one of claims 1 to 9, characterized in that, The working method is as follows: The dough is placed on the receiving tray, which weighs the dough. If the weight is within acceptable limits, the guide seat moves to rotate the drive shaft. As the drive shaft rotates, it drives the receiving tray to rotate, so that the dough is poured into the first conveyor. This allows the first conveyor to continuously transport the dough to the end away from the receiving tray. The movement of the guide seat causes the connecting column to push the drive seat to move, thereby causing the first and second connecting rods of each set of cross components to swing toward the first conveyor, causing each cutter to swing toward the end point of the first conveyor and toward the middle of the first conveyor, forming an action of cutting the dough located on the first conveyor.
