Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0035] The present invention provides a bread production line device and a working method thereof which can automatically weigh and shape bread. Figures 1 to 6 As shown, the device includes a receiving plate 1, a guide mechanism 2, a cutting mechanism 3 and a driving mechanism 4. The driving mechanism 4 is used to drive the guiding mechanism 2 and the cutting mechanism 3 to work, so that the guiding mechanism 2 drives the receiving plate 1 to move linearly and rotate. After the receiving plate 1 receives the dough and weighs it, the dough with qualified weight is poured downward into the cutting mechanism 3 by turning it over for cutting, exhausting and shaping. Preferably, the device of the present invention can also be configured with a control system, which is used to receive the weight signal sensed by the receiving plate 1 and control the operation of the driving device.

[0036] The receiving tray 1 has a built-in weighing module for weighing the 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 detects whether the weight of the dough is within a qualified weight value through the control system.

[0037] As attached Figures 7 to 9 As shown, the guide mechanism 2 includes a guide tunnel 21, a guide seat 22 and a drive shaft 23. The inner wall of the guide tunnel 21 is recessed to form a guide groove 211, and the guide 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 guide tunnel 21 and is a 180° spiral. The first straight groove 2111 and the second straight groove 2112 are respectively arranged on both sides of the guide groove 211, and the first straight groove 2111 and the second straight groove 2112 are parallel to each other and arranged horizontally. 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 arranged in the connecting frame 24, and the sliding rails 251 are fixed on both sides of the connecting frame 24. The sliding rails 251 are parallel to the first straight groove 2111 and the second straight groove 2112, and the two sliding rails 251 are adapted to connect the sliders 252, and the two sides of the guide seat 22 are respectively fixed to the sliders 252 of the two sliding rails 251, thereby limiting the guide seat 22 to be located under the guide tunnel 21 and can only move parallel to the straight extension direction of the first straight groove 2111 or the second straight groove 2112.

[0038] As attached Figure 8 As shown, a connecting column 221 is also provided below the guide seat 22. Fig.10 The driving mechanism 4 includes a driving motor 43, a first swing rod 41 and a second swing rod 42. The driving motor 43 is fixed below the guide tunnel 21, and the output shaft of the driving motor 43 is fixedly connected to one end of the first swing rod 41, and the two ends of the second swing rod 42 are respectively pivoted to one end of the first swing rod 41 and the connecting column 221. In this structure, when the driving motor 43 drives the first swing rod 41 to rotate, the second swing rod 42 can be pulled or pushed to move accordingly, thereby driving the guide seat 22 to move, that is, the guide seat 22 is driven to move by the driving motor 43.

[0039] 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, and the axis center line of the drive shaft 23 is coaxial with the axis center line of the spiral line of the spiral groove 2113. The specific connection method of the drive shaft 23 and the guide seat 22 can be that the two ends of the guide seat 22 are embedded with bearings, and after the drive shaft 23 passes through the inner rings of the two bearings, the drive shaft 23 is equipped with a retaining spring at the edge position of the two bearings facing the middle side of the guide seat 22, and the two retaining springs are respectively blocked at the two bearings to limit the drive shaft 23 from moving relative to the guide seat 22 and fix it axially, and the drive shaft 23 can only rotate relative to the guide seat 22. In addition, one end of the drive shaft 23 is fixed to the receiving plate 1, so that when the drive shaft 23 rotates, the receiving plate 1 can be turned over. A guide portion 231 is provided on the side of the other end of the drive shaft 23, and the guide portion 231 is adapted to be embedded in the guide groove 211 and moves along the guide groove 211. When the guide seat 22 moves and drives the driving shaft 23 and the receiving plate 1 to move in the direction of the guided tunnel 21, the guide portion 231 moves along the guide groove 211, and a movement process from the first straight groove 2111 to the second straight groove 2112 via the spiral groove 2113 can be formed. This process drives the driving shaft 23 to rotate and turns the receiving plate 1 to pour the dough onto the cutting mechanism 3. Preferably, the guide portion 231 is connected to a roller, and the roller is adapted to be embedded in the guide groove 211 and rotated to reduce the friction of the guide portion 231 moving in the guide groove 211, thereby improving the smoothness of the operation of the guide shaft.

[0040] As attached Figures 13 to 16 As shown, the cutting mechanism 3 includes a first conveyor 31, a driving 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. Fig.14 As shown, the driving seat 32 is provided with a long strip-shaped limiting hole 321 along the conveying direction of the first conveyor 31, and a second gantry 391 is fixed above the first conveyor 31. The second gantry 391 is fixed with upwardly protruding limiting posts 392 at positions corresponding to both ends of the first conveyor 31. Both limiting posts 392 are adapted to pass through the limiting holes 321, so that the driving seat 32 is limited to move linearly along the conveying direction of the first conveyor 31. Two first gantries 241 are fixed under the connecting frame 24 of the guide mechanism 2, and both first gantries 241 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 limit rods 36 are pivotally connected above the first conveyor 31, and the pivoting method is that a rotating shaft is fixed on the second gantry 391, one end of the two first limit rods 36 is overlapped and sleeved on the rotating shaft to form a pivot connection, and the rotating shaft is equipped with a retaining spring on the first limit rod 36 located above to limit the ends of the two first limit rods 36 to the rotating shaft.

[0041] The driven seat 33 is pivoted to two second limiting rods 37, and the two second limiting rods 37 are fixed with gears (not shown in the drawings) at one end in the driven seat 33, and the two gears are meshed with each other, so that the two second limiting rods 37 swing synchronously and oppositely relative to the driven seat 33. A cross assembly consisting of a plurality of groups of cross-pivoted first connecting rods 34 and second connecting rods 35 is arranged between the driving seat 32 and the driven seat 33. In each group of cross assemblies, the two first limiting rods 36 are respectively pivoted to the first connecting rod 34 and the second connecting rod 35 in the cross assembly at one end, and the second limiting rod 37 is respectively pivoted to the first connecting rod 34 and the second connecting rod 35 in the cross assembly at the other end, and the middle position where the first connecting rod 34 and the second connecting rod 35 of the cross assembly at the other end are pivoted to the driving seat 32. At the same time, in each group of cross assemblies, the two ends of the first connecting rod 34 are respectively pivoted to the second connecting rod 35 of the adjacent cross assembly, and the two ends of the second connecting rod 35 are respectively pivoted to the first connecting rod 34 of the adjacent cross assembly. The bottom of the first connecting rod 34 or the second connecting rod 35 is also fixed with a cutter 38, and the cutter 38 extends to the conveying surface of the first conveyor 31. With the above structure, when the guide seat 22 moves to make the connecting column 221 move accordingly, the connecting column 221 pushes the driving seat 32 to move accordingly, so that the driving seat 32 moves and drives the first connecting rod 34 and the second connecting rod 35 pivotally connected to the driving seat 32 to swing in a direction flush with the length direction of the first conveyor 31, thereby driving the first connecting rod 34 and the second connecting rod 35 of each group of cross components to swing accordingly, 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 transported on the first conveyor 31.

[0042] Please refer to the attached Fig.16 Two second gantries 391 are fixed on the first conveyor 31, and the second conveyor 39 is connected to the second conveyor 39 below the two second gantries. The second conveyor 39 is located above the first conveyor 31, so that each cutter 38 is located between the first conveyor 31 and the second conveyor 39, and the conveyor belt of the first conveyor 31 and the conveyor belt of the second conveyor 39 have the same running speed, and 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 have the same running direction. Figure 1 and 6 The direction from right to left is shown. When the dough is conveyed between the first conveyor 31 and the second conveyor 39, the conveyor belt of the first conveyor 31 and the conveyor belt of the second conveyor 39 can form a state of clamping and conveying the dough, so as to prevent the cutter 38 from being unable 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, and the two guide plates 393 are inclined toward 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 conveyance.

[0043] As attached Fig.11 and 12 As shown, a pusher 44 is provided below the connecting column 221, and the pusher 44 and the connecting column 221 are connected by a first spring 45. A first guide surface is provided above the driving seat 32 facing the connecting column 221. When the connecting column 221 pushes the driving seat 32 against the first guide surface to move until the driving seat 32 is stuck, the pusher 44 moves upward along the first guide surface to the top of the driving seat 32 and continues to move and compress the first spring 45. Compared with the method in which the connecting column 221 is directly connected to the driving seat 32 to drive the driving seat 32 to move, this structure can shorten the stroke of the connecting column 221 to push the driving seat 32 to move, thereby reducing the overall length of the cutting mechanism 3, and preventing the cutting mechanism 3 from extending out of the space above one end of the first conveyor 31 away from the receiving plate 1 after being stretched, which makes it difficult for the staff to take the shaped dough in this space.

[0044] Please refer to the attached Figure 4 , a receiving hole is formed inside the lower end of the connecting column 221, and a strip hole 222 penetrating both sides is also provided on the side of the connecting column 221, the strip hole 222 is vertically arranged, and the strip hole 222 is connected to the receiving hole, and the connecting pin is fixed on the pusher 44. A limit pin 46 is fixed on the side of the connecting pin, and preferably, the limit pin 46 can be a bolt. During assembly, the first spring 45 and the connecting pin are sequentially embedded in the receiving hole, and then the limit pin 46 is passed through the strip hole 222 and the connecting pin is spirally connected. The connection pin can only move vertically along the strip hole 222 relative to the connecting column 221 through the restriction of the limit pin 46, and the elastic force of the first spring 45 stretching pushes the connecting pin downward until the limit pin 46 is against the lower end of the strip hole 222. When the guide seat 22 moves to drive the connecting column 221 to push toward the drive seat 32, the pusher 44 moves upward along the first guide surface to the top of the drive seat 32 and continues to move and compress the first spring 45.

[0045] Please refer to the attached Fig.13 and 16 , the second spring 331 is fixed on the side of the driven seat 33 facing away from the driving seat 32, and the first gantry 241 is fixed on the first conveyor 31. When the connecting column 221 pushes the driving seat 32 to move until the driving seat 32 is stuck, the driven seat 33 moves to compress the second spring 331 against the first gantry 241. The state where the driving seat 32 moves to the stuck state can be that the end of the driving seat 32 away from the connection between the first connecting rod 34 and the second connecting rod 35 presses against the rotating shaft and cannot continue to move; or it can also be as shown in the attached Fig.16One end of the driven seat 33 shown is pressed against the first gantry 241, so that each group of cross components cannot continue to swing, thereby preventing the driving seat 32 from moving further. When the driving seat 32 cannot continue to move and the pusher 44 compresses the first spring 45 and moves upward, the pusher 44 and the connecting column 221 cannot block the driving seat 32 and the second spring 331. Therefore, the elastic force of the second spring 331 resets and stretches to push the driven seat 33 to move in the direction of the driving seat 32, so that the two second limit rods 37 swing outward on both sides of the driven seat 33, driving the first connecting rod 34 and the second connecting rod 35 in each group of cross components to swing in a direction flush with the width direction of the first conveyor 31, thereby driving the first connecting rod 34 and the second connecting rod 35 in each group of cross components to swing accordingly, so that each cutter 38 swings backward and to both sides of the first conveyor 31 synchronously to form a cutting action, thereby cutting the dough being transported on the first conveyor 31.

[0046] The cutting blades 38 perform a cutting action to cut the dough conveyed on the first conveyor 31, so that the inside of the dough is exposed, thereby exhausting the air inside the dough. A rotatable pressing roller 310 is also provided near the terminal end of the first conveyor 31. The pressing roller 310 is arranged transversely to the first conveyor 31, and there is a gap between the pressing roller 310 and the upper surface of the conveyor belt of the first conveyor 31. When the dough passes through the cutting blades 38 and is cut, and then passes under the pressing roller 310, the pressing roller 310 rotates accordingly and compacts the cut dough.

[0047] In addition, as attached Figure 1 and 6As shown, the device of the present invention further comprises a sorting mechanism 5, which comprises a driving cylinder 53 and a push plate 51, wherein the driving cylinder 53 is an actuator such as a cylinder, an oil cylinder or an electric push rod with a piston rod in the prior art, and the control system controls the driving cylinder 53 to work. The driving cylinder 53 is fixed obliquely above the receiving tray 1, and specifically, a third gantry can be fixed above the connecting frame 24, and the driving cylinder 53 is fixed on the third gantry to avoid the activity space of the receiving tray 1. The piston rod end of the driving cylinder 53 is fixed to the push plate 51. When the weight of the dough weighed by the bearing tray is unqualified, the control system controls the piston rod of the driving cylinder 53 to extend so that the push plate 51 directly pushes the dough on the receiving tray 1 out of the receiving tray 1, and slides down from the hopper 54 fixed on the starting end of the first conveyor 31. Preferably, a frame (not shown in the drawings) can also be placed at the lower end of the hopper 54 to receive the dough with unqualified weight. Furthermore, the sorting mechanism 5 further comprises a telescopic plate 52, and both sides of the front of the push plate 51 are provided with limiting grooves 511, and both sides of the telescopic plate 52 are adapted to be inserted into the two limiting grooves 511, so that the telescopic plate 52 can telescopically move relative to the push plate 51, and both sides of the upper part of the telescopic plate are fixed with blocking parts 521, and the telescopic plate 52 can be prevented from falling and separating from the push plate 51 by the blocking parts 521 blocking above the limiting grooves 511. When the push plate 51 moves obliquely downward onto the receiving plate 1, the telescopic plate 52 moves to abut against the plate surface of the receiving plate 1, and as the piston rod extends, the telescopic plate 52 is raised relative to the receiving plate and moves forward parallel to the receiving plate, so as to prevent the push plate 51 from moving downward to the middle position of the plate surface of the receiving plate 1 and being unable to push the dough out of the receiving plate 1. Furthermore, pulleys 522 are provided on both sides of the lower end of the telescopic plate 52 to improve the smoothness of the parallel movement of the telescopic plate 52 on the receiving plate 1.

[0048] In a second aspect, the present invention also discloses a working method of the above device, which is as follows: 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 and rotate the drive shaft 23, so that the drive shaft 23 rotates and drives the receiving tray 1 to rotate until the dough is poured into the first conveyor 31, so that the first conveyor 31 can continuously convey the dough to the end away from the receiving tray 1. The guide seat 22 moves so that the connecting column 221 pushes the driving seat 32 to move, so as to drive the first connecting rod 34 and the second connecting rod 35 of each group of cross components to swing in the direction aligned with the length of the first conveyor 31, so that each cutter 38 swings toward the terminal end of the first conveyor 31 and toward the middle of the first conveyor 31, thereby forming an action of cutting the dough on the first conveyor 31; When the driving seat 32 moves to the end end of the first conveyor 31 and is stuck, the driven seat 33 moves to compress the second spring 331 against the first gantry 241, and the pushing member 44 moves upward and compresses the first spring 45, so that the pushing member 44 and the connecting column 221 cannot block the driving seat 32 and therefore cannot block the second spring 331, so that the elastic force of the second spring 331 resets and stretches and pushes the driven seat 33 to move toward the starting end of the first conveyor, driving the first connecting rod 34 and the second connecting rod 35 in each group of cross components to swing in a direction aligned with the width of the first conveyor 31, so that each cutter 38 swings toward the starting end of the first conveyor 31 and to both sides of the first conveyor 31 to form a cutting action, thereby cutting the dough on the first conveyor 31 for transportation again.

[0049] As can be seen from the above working method, the present invention moves the guide seat 22 to make the drive shaft 23 rotate and drive the receiving plate 1 to rotate until the dough that has been weighed and qualified 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 and drive 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 pouring the dough that has been weighed and qualified after automatic weighing into the first conveyor 31 by moving the guide seat 22, and at the same time drive the first connecting rod 34 and the second connecting rod 35 to swing to realize cutting the dough. It can be seen that the present invention can realize automatic weighing of continuous dough and continuous cutting of both sides of the dough that has been weighed and qualified, so as to expose the inside of the dough, thereby exhausting the air inside the dough, and completing the automatic exhaust work in dough shaping.

[0050] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
