Description

Technical Field

[0001] The present application relates to the field of pastry production, and in particular, to a multi-channel flower-pinching mechanism. Background Art

[0002] Pastries can be divided into filled types (such as pies, etc.) and unfilled types (such as cakes, toast bread, etc.). Filled pastries usually require wrapping the dough around the filling, while for unfilled pastries, seasonings are usually mixed into the dough. The purpose of both is to improve the edible taste of the pastries.

[0003] During the processing of filled pastries, the prepared filling needs to be placed on the dough first, and then the filling is wrapped inside the dough. To improve the appearance quality of the product, a flower-pinching machine is usually used to make the dough wrapped with the filling into a specific shape. During the processing of unfilled pastries, the dough needs to be seasoned first (such as mixing in other ingredients like cream, egg liquid, nut crumbs, etc.), rolled into a long strip, and then the dough is made into a set shape by a cutting or shaping mechanism. Subsequently, the flower-pinched or cut dough will be transported to an oven for baking.

[0004] The production processes of the above-mentioned filled pastries and unfilled pastries are different, so two different processing devices are required to meet the production needs. However, the production methods of the two types of pastries also have similarities. For example, for filled pastries, the dough also needs to be rolled into a long strip in its initial state, and then the filling is evenly placed on the dough along the length direction of the dough. The conventional method of separately processing filled pastries and unfilled pastries using two different processing devices occupies a large area, resulting in a low space utilization rate at the production site and further improvement is needed. Summary of the Utility Model

[0005] In order to improve the space utilization rate at the production site of filled pastries and unfilled pastries, the present application provides a multi-channel flower-pinching mechanism.

[0006] The multi-channel flower-pinching mechanism provided by the present application adopts the following technical solutions:

[0007] A multi-channel flower-kneading mechanism, comprising a main frame, a sub-frame, a main conveying component, a flower-kneading machine, a second conveying component and a third conveying component. The main conveying component is arranged on the main frame. One end of the main frame is the feeding end, and the other end is the discharging end. The main conveying component is used for conveying the dough along the feeding end to the discharging end of the main frame. The sub-frame is arranged at the discharging end of the main frame, and the flower-kneading machine is arranged between the main frame and the sub-frame. The sub-frame includes an upper layer frame and a lower layer frame. The upper layer frame is erected on the lower layer frame, and the second conveying component is arranged on the upper layer frame. The third conveying component is arranged on the lower layer frame. One end of the third conveying component is connected to the discharging port of the flower-kneading machine, and the other end is connected to the baking oven. The third conveying component is used for conveying the dough with flowers kneaded to the baking oven. One end of the second conveying component is connected to the discharging end of the main frame, and the other end is connected to the baking oven. The second conveying component is used for conveying the long strip-shaped dough.

[0008] By adopting the above technical solution, the dough is conveyed by the main conveying component. When the dough reaches the discharging end of the main frame, there will be two conveying paths along the second conveying component or the third conveying component. When producing filled pastries, the dough will fall into the feeding port of the flower-kneading machine when it reaches the discharging end of the main frame. The dough after being kneaded by the flower-kneading machine reaches the third conveying component along the discharging port of the flower-kneading machine and is conveyed to the baking oven through the third conveying component. At the same time, when producing unfilled pastries, the long strip-shaped dough directly enters the second conveying component after reaching the discharging end of the main frame, and the dough is conveyed to the baking oven through the second conveying component. The above process integrates the production of unfilled pastries and filled pastries, and can be flexibly switched between the production of unfilled pastries and filled pastries at any time without changing the production site. Since the upper layer frame is erected on the lower layer frame, the space utilization rate of the production site is improved.

[0009] Preferably, a limiting component is arranged along the width direction of the main frame. The limiting component includes an adjusting plate, a first limiting wheel set and a second limiting wheel set. The adjusting plate is erected above the main conveying component along the width direction of the frame. The first limiting wheel set and the second limiting wheel set are slidably arranged on the adjusting plate along the length direction of the adjusting plate, and a gap for the dough to pass through is formed between the first limiting wheel set and the second limiting wheel set.

[0010] By adopting the above technical solution, since the dough piece is soft, during the transportation process, the transportation path of the dough piece is limited by the first limiting wheel set and the second limiting wheel set, so that the dough piece can accurately fall into the feeding port of the flower kneading machine or the dough piece can be stably transported along the second transportation component, reducing the probability of the dough piece falling due to the deviation of the position of the dough piece when reaching the connection between the main transmission component and the flower kneading machine / or the second transmission component. At the same time, since the first limiting wheel set and the second limiting wheel set can slide along the adjusting plate, the gap size between the first limiting wheel set and the second limiting wheel set can be adjusted to meet the limiting requirements of dough pieces of different widths.

[0011] Preferably, the first limiting wheel set and the second limiting wheel set are rotationally carried on the adjusting plate. When the first limiting wheel set and / or the second limiting wheel set rotate, the transportation path of the dough piece along the gap changes synchronously.

[0012] By adopting the above technical solution, when the dough piece cannot accurately fall into the feeding port of the flower kneading machine, by rotating the first limiting wheel set and / or the second limiting wheel set, the transportation path of the dough piece along the main transmission component is changed, and the deviation between the transportation path of the dough piece and the feeding port of the flower kneading machine can be corrected by adjustment.

[0013] Preferably, an auxiliary guiding component is arranged on the main frame above the flower kneading machine. The auxiliary guiding component includes two rotating plates and a bearing shaft. One end of each of the two rotating plates is rotationally carried on the two side walls along the width direction of the discharging end of the main frame. Through holes are formed at the free ends of the two rotating plates. The bearing shaft is rotationally carried in the through holes, and the rotation angles of the two rotating plates are between 0° and 135°.

[0014] By adopting the above technical solution, when producing a pastry without filling, when the long strip-shaped dough piece is transported to the discharging end of the main frame through the main transmission component, the dough piece can reach the second transmission component along the surface of the bearing shaft. Through the supporting action of the bearing shaft, the dough piece can receive the supporting force provided by the bearing shaft when passing between the main transmission component and the second transmission component, thereby reducing the deformation degree of the long strip-shaped dough piece when passing between the main transmission component and the second transmission component, and making the shapes of the long strip-shaped dough pieces on the main transmission component and the second transmission component substantially the same; at the same time, when producing a pastry with filling, the rotating plate can be rotated to 135°, so that the dough piece can fall into the feeding port of the flower kneading machine along the space between the main frame and the second transmission component, reducing the probability of the situation that the dough piece cannot smoothly fall into the feeding port of the flower kneading machine due to the bearing shaft being located between the main transmission component and the second transmission component.

[0015] Preferably, a magnetic attraction member is provided on the side wall of the discharging end of the main frame along its width direction. When the rotating plate rotates to 135° along the discharging end of the main frame, the magnetic attraction member is magnetically engaged with the rotating plate.

[0016] By adopting the above technical solution, when producing filled pastries, the rotating plate needs to be rotated to 135° along the discharging end of the main frame. Since the main transmission assembly will vibrate during transportation, the rotating plate is adsorbed by the magnetic attraction member, reducing the probability of the situation that the rotating plate rotates back between the main frame and the second transmission assembly due to the vibration of the main transmission assembly.

[0017] Preferably, the auxiliary guiding assembly further includes an auxiliary supporting wheel. The auxiliary supporting wheel is rotatably carried on the carrying shaft, and the auxiliary supporting wheel can slide along the length direction of the carrying shaft.

[0018] By adopting the above technical solution, when producing unfilled pastries, the strip-shaped dough is supported by the auxiliary supporting wheel, reducing the probability of the dough deforming due to the influence of gravity. At the same time, the transportation path of the dough is limited by the auxiliary supporting wheel, so that the dough can be in a straight line when being transported between the main transmission assembly, the auxiliary supporting wheel and the second transmission assembly. And the auxiliary supporting wheel can slide along the length direction of the carrying shaft. Therefore, the position of the auxiliary supporting wheel on the carrying shaft can be adjusted to adapt to the dough transportation path adjusted by the first limiting wheel set and the second limiting wheel set.

[0019] Preferably, a cutting component is provided on the upper layer frame. The cutting component includes a driving cylinder and a cutting knife. The driving cylinder is arranged on the upper layer frame above the second transmission assembly. The piston rod of the driving cylinder faces the second transmission assembly. Sliding rods 211 are arranged on both sides of the upper layer frame along its width direction. The spatial position relationship between the sliding rods 211 and the upper layer frame is perpendicular. The cutting knife is slidably arranged on the sliding rods 211, and the cutting knife is fixedly connected to the piston rod of the driving cylinder. When the piston rod of the driving cylinder acts, the cutting knife follows the piston rod of the driving cylinder to act synchronously.

[0020] By adopting the above technical solution, when the strip-shaped dough reaches the second transmission assembly, the working state of the driving cylinder can be controlled to make the cutting knife slide up and down along the sliding rods 211. When the cutting knife descends, the strip-shaped dough transported along the second transmission assembly can be cut off, so that the dough is cut off during transportation, improving the production efficiency of unfilled pastries to a certain extent.

[0021] Preferably, the upper layer frame is arranged to be inclined downward from the end connected to the discharging end of the main frame to the end connected to the baking oven.

[0022] By adopting the above technical solution, when the dough reaches the end of the second conveying component, the dough directly drops onto the baking oven at this time. If the vertical distance between the second conveying component and the baking oven is too large, the dough will deform when it drops onto the baking oven, making it unable to meet the design requirements and reducing the appearance quality of the product. Therefore, since the upper layer rack is arranged to slope downwards, the second conveying component arranged on the upper layer rack is also in an inclined state, reducing the vertical distance between the second conveying component and the baking oven, thereby reducing the degree of deformation of the dough when it drops onto the baking oven.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The main conveying component is used to convey the dough to the discharge end of the main frame. When producing filled pastries, the dough drops from the discharge end of the main frame into the feeding port of the flower shaping machine, and after being processed by the flower shaping machine, it enters the third conveying component and is transported to the baking oven; when producing unfilled pastries, when the dough is transported to the discharge end of the main frame by the main conveying component, it directly enters the second conveying component and is transported to the baking oven by the second conveying component. Thus, filled pastries and unfilled pastries can be produced on the same production line and can be switched at any time without changing the production site, improving the space utilization rate of the production site.

[0025] 2. When producing unfilled pastries, the long strip-shaped dough reaches the discharge end of the main frame through the main conveying component and is conveyed along the surface of the bearing shaft to the second conveying component. The bearing shaft reduces the degree of deformation of the dough when it reaches the second conveying component through the main conveying component. When producing filled pastries, by rotating the rotating plate to 135°, the dough can smoothly drop into the feeding port of the flower shaping machine, reducing the possibility that the dough cannot drop smoothly due to the obstruction of the bearing shaft.

[0026] 3. The upper layer rack slopes downwards from the end connected to the discharge end of the main frame to the end connected to the baking oven, thereby reducing the vertical distance between the second conveying component and the baking oven and reducing the probability of the dough deforming when it drops onto the baking oven due to the excessive vertical distance between the second conveying component and the baking oven.

Detailed implementation manners

[0030] The following further elaborates on this application Figure 1-2 in conjunction with the attached drawings.

[0031] An embodiment of this application discloses a multi-channel flower pinching mechanism. Refer to Figure 1 , a multi-channel flower pinching mechanism includes a main frame 1, a sub-frame 2, a main conveying component, a flower pinching machine 4, a second conveying component, and a third conveying component. The main conveying component is arranged on the main frame 1. The main conveying component includes a first conveyor belt 3 and a first motor pulley conveying component. The first conveyor belt 3 is rotationally carried on the main frame 1. One end of the main frame 1 is the feeding end, and the other end is the discharging end. The first motor pulley conveying component is arranged on the main frame 1. The first conveyor belt 3 is driven to rotate through the first motor pulley conveying component, so as to realize the transportation of the dough from the feeding end to the discharging end of the main frame 1 along the first conveyor belt 3. At the same time, the sub-frame 2 is arranged at the discharging end of the main frame 1.

[0032] Furthermore, the flower pinching machine 4 is arranged between the main frame 1 and the sub-frame 2. The flower pinching machine 4 is a conventional flower pinching device for pastry production. After the dough reaches the feeding port of the flower pinching machine 4, the upper flower pinching die and the lower flower pinching die of the flower pinching machine 4 cooperate to pinch the dough, so that the surface of the dough has a pattern that meets the design requirements. Its specific composition and working principle will not be elaborated too much here.

[0033] Meanwhile, the sub-frame 2 includes an upper frame 21 and a lower frame 22. The upper frame 21 is installed on the lower frame 22. The second conveyor assembly is arranged on the upper frame 21, and the third conveyor assembly is arranged on the lower frame 22. The second conveyor assembly includes a second conveyor belt 5 and a second motor pulley conveyor assembly. The second conveyor belt 5 is rotatably carried on the upper frame 21, and one end of the second conveyor belt 5 is connected to the discharge end of the main frame 1, and the other end is connected to the baking oven. The second motor pulley conveyor assembly is arranged on the upper frame 21 to drive the second conveyor belt 5 to rotate through the second motor pulley conveyor assembly for transporting long strip-shaped dough pieces. At the same time, the third conveyor assembly includes a third conveyor belt 6 and a third motor pulley conveyor assembly. The third conveyor belt 6 is rotatably carried on the lower frame 22, and one end of the third conveyor belt 6 is connected to the discharge port of the flower molding machine 4, and the other end is connected to the baking oven. The third motor pulley conveyor assembly is arranged on the lower frame 22 to drive the third conveyor belt 6 to rotate through the third motor pulley conveyor assembly, realizing the operation of transporting the dough pieces completed by flower molding to the baking oven by the third conveyor belt 6.

[0034] Correspondingly, the upper frame 21 is arranged to be downwardly inclined from the end connected to the discharge end of the main frame 1 to the end connected to the baking oven. When the dough piece reaches the end of the second conveyor belt 5, if the vertical distance between the second conveyor belt 5 and the baking oven is too large, the dough piece may be deformed when it falls onto the baking oven, resulting in the product not meeting the appearance design requirements and thus reducing the appearance quality. To solve this problem, the upper frame 21 is arranged to be downwardly inclined, so as to reduce the vertical distance between the second conveyor belt 5 and the baking oven, thereby reducing the degree of deformation of the dough piece when it falls onto the baking oven.

[0035] It should be noted that the first motor pulley conveyor assembly, the second motor pulley conveyor assembly, and the third motor pulley conveyor assembly are all composed of a driving motor, a pulley, and a belt, which are conventional power transmission components in the mechanical field. And the baking oven is a conventional baking device for pastry making. The dough piece is carried by a conveyor belt and passes through the oven. When the dough piece is irradiated by high temperature, the moisture evaporates rapidly, and at the same time the pastry is baked. Its specific composition and working principle will not be elaborated here too much.

[0036] Refer to Figure 1 and Figure 2 , a limiting component 7 is arranged along the width direction of the main frame 1. The limiting component 7 includes an adjusting plate 71, a first limiting wheel group 72, and a second limiting wheel group 73. The adjusting plate 71 is installed at the discharge end of the main frame 1, and the adjusting plate 71 is arranged above the first conveyor belt 3 along the width direction of the frame. The first limiting wheel group 72 and the second limiting wheel group 73 are slidably arranged on the adjusting plate 71 along the length direction of the adjusting plate 71, and a gap for the dough piece to pass through is formed between the first limiting wheel group 72 and the second limiting wheel group 73.

[0037] Specifically, the first limiting wheel set 72 and the second limiting wheel set 73 have the same composition and installation method. Here, the first limiting wheel set 72 will be described in detail. The first limiting wheel set 72 includes a limiting plate 721, an adjusting nut 722, and a plurality of limiting wheels 723. The outer contour of the limiting plate 721 is arranged in a cuboid shape. In this embodiment, seven limiting wheels 723 are provided. Any one of the limiting wheels 723 is vertically and rotatably carried on the limiting plate 721, and the seven limiting wheels 723 are evenly distributed on the limiting plate 721.

[0038] At the same time, a waist-shaped groove 7211 is formed in the limiting plate 721 along its length direction. A pressing piece 7221 is coaxially fixed to the threaded section of the adjusting nut 722, and the threaded section of the adjusting nut 722 is threadedly connected to the limiting plate 721. Therefore, when the adjusting nut 722 is placed in the waist-shaped groove 7211, the pressing piece 7221 abuts against the upper surface of the adjusting plate 71. At this time, the threaded section of the adjusting nut 722 passes through the waist-shaped groove 7211 and is threadedly connected to the limiting plate 721. The operator can adjust the distance between the first limiting wheel set 72 and the second limiting wheel set 73 by loosening or tightening the locking nut, so that it can adapt to the limiting requirements of different widths of dough sheets, enabling the dough sheets to accurately fall into the feeding port of the flower shaping machine 4 or the second conveyor belt 5, and reducing the probability of the dough sheets falling when reaching the first conveyor belt 3 and the flower shaping machine 4 / or the second conveyor belt 5 due to the deviation of the dough sheet position.

[0039] Furthermore, after the conveying path of the dough sheet is limited by the first limiting wheel set 72 and the second limiting wheel set 73, the conveying path of the dough sheet along the first conveyor belt 3 changes. When the dough sheet cannot accurately fall into the feeding port of the flower shaping machine 4, the angle between the first limiting wheel set 72 and / or the second limiting wheel set 73 along the limiting plate 721 can be adjusted by loosening the adjusting nut 722, thereby correcting the deviation between the conveying path of the dough sheet along the first conveyor belt 3 and the feeding port of the flower shaping machine 4.

[0040] Refer to Figure 1 and Figure 2, an auxiliary guiding component 8 is provided on the main frame 1 above the flower kneading machine 4. The auxiliary guiding component 8 includes two rotating plates 81 and a bearing shaft 82. One end of each of the two rotating plates 81 is rotatably borne on the two side walls along the width direction of the discharging end of the main frame 1. Through holes are provided at the free ends of the two rotating plates 81, and the bearing shaft 82 is rotatably borne in the through holes. Moreover, the rotation angle of the two rotating plates 81 is between 0° and 135°. When producing pastry without filling, when the strip-shaped dough is transported to the discharging end of the main frame 1 through the first conveyor belt 3, the dough can reach the second conveyor belt 5 along the surface of the bearing shaft 82. Through the supporting action of the bearing shaft 82, the dough can receive the supporting force provided by the bearing shaft 82 when passing between the first conveyor belt 3 and the second conveyor belt 5, thereby reducing the degree of deformation of the strip-shaped dough when passing between the first conveyor belt 3 and the second conveyor belt 5, and making the shapes of the strip-shaped dough on the first conveyor belt 3 and the second conveyor belt 5 roughly the same. At the same time, when producing pastry with filling, the rotating plate 81 can be rotated to 135°, so that the dough can fall between the main frame 1 and the second conveyor belt 5 to the feeding port of the flower kneading machine 4, reducing the probability that the dough cannot smoothly fall to the feeding port of the flower kneading machine 4 due to the bearing shaft 82 being located between the first conveyor belt 3 and the second conveyor belt 5.

[0041] Further, the auxiliary guiding component 8 further includes an auxiliary supporting wheel 83. The auxiliary supporting wheel 83 is rotatably borne on the bearing shaft 82, and the auxiliary supporting force can slide along the length direction of the bearing seat. When producing pastry without filling, in order to reduce the possibility of the dough deforming under the influence of gravity, the auxiliary supporting wheel 83 is used to provide additional support. The auxiliary supporting wheel 83 defines the transportation path of the dough, making it in a straight line when passing through the first conveyor belt 3, the auxiliary supporting wheel 83 and the second conveyor belt 5. The auxiliary supporting wheel 83 can slide along the length direction of the bearing shaft 82, so the position of the auxiliary supporting wheel 83 on the bearing shaft 82 can be adjusted to adapt to the dough transportation path adjusted by the first limiting wheel set 72 and the second limiting wheel set 73. Such a design can effectively control the transportation process of the dough, reduce the occurrence of deformation, and ensure the stability of the dough during transportation.

[0042] Refer to Figure 1 and Figure 2 , a magnetic component 9 is provided on the side wall along the width direction of the discharging end of the main frame 1. The magnetic component 9 can be set as a magnet. When the rotating plate 81 rotates to 135° along the discharging end of the main frame 1, the magnetic component 9 is magnetically coupled with the rotating plate 81. When producing pastry with filling, it is necessary to rotate the rotating plate 81 to 135° along the discharging end of the main frame 1. Since the first conveyor belt 3 will vibrate during transportation, the rotating plate 81 is adsorbed by the magnetic component 9, reducing the probability that the rotating plate 81 rotates back between the main frame 1 and the second conveyor belt 5 due to the vibration of the main transmission component.

[0043] Referring to Figure 1 , a cutting component 10 is provided on the upper shelf 21. The cutting component 10 includes a driving cylinder 101 and a cutting knife 102. The driving cylinder 101 is arranged on the upper shelf 21 above the second conveying component. The piston rod of the driving cylinder 101 faces the second conveying component. On both sides of the upper shelf 21 along its width direction, sliding rods 211 are provided. The spatial position relationship between the sliding rods 211 and the upper shelf 21 is perpendicular. The cutting knife 102 is slidably arranged on the sliding rods 211, and the cutting knife 102 is fixedly connected to the piston rod of the driving cylinder 101. When the piston rod of the driving cylinder 101 moves, the cutting knife 102 moves synchronously with the piston rod of the driving cylinder 101.

[0044] Specifically, a bearing plate 51 is erected above the second conveyor belt 5. Both ends of the bearing plate 51 are fixedly connected to the sliding rods 211 respectively, and the sliding rods 211 are perpendicular to the bearing plate 51. The driving cylinder 101 is fixedly connected to the bearing plate 51, and the piston rod of the driving cylinder 101 faces the second conveyor belt 5. Therefore, when the piston rod of the driving cylinder 101 moves, the cutting knife 102 fixedly connected to the piston rod of the driving cylinder 101 moves synchronously with the piston rod of the driving cylinder 101, realizing the cutting operation on the long strip-shaped dough conveyed along the second conveyor belt 5.

[0045] At the same time, sliding sleeves 2111 are respectively slidably arranged on the two sliding rods 211, and both ends of the cutting knife 102 along its length direction are fixedly connected to the sliding sleeves 2111, so that the cutting knife 102 can stably slide up and down along the sliding rods 211, reducing the yaw when the cutting knife 102 slides up and down. Thus, when the driving cylinder 101 bears the cutting knife 102 to cut the long strip-shaped dough conveyed along the second conveyor belt 5, the acting forces applied to the dough are relatively balanced everywhere, reducing the number of occurrences of the dough sticking during cutting.

[0046] The implementation principle of a multi-channel flower-knitting mechanism in an embodiment of the present application is as follows: The dough is conveyed by using the main conveying component. When the dough reaches the discharge end of the main frame 1, two different conveying paths can be selected, namely the second conveying component and the third conveying component. When producing filled pastries, the dough reaching the discharge end of the main frame 1 will fall into the feed inlet of the flower-knitting machine 4, and then the dough after being flower-knitted by the flower-knitting machine 4 enters the third conveying component through the discharge port and is finally conveyed to the baking oven through this component. At the same time, when producing unfilled pastries, the long strip-shaped dough directly enters the second conveying component and is conveyed to the baking oven through this component. This process integrates the production of unfilled pastries and filled pastries, allowing for flexible switching between unfilled pastries and filled pastries at any time without changing the production site. Since the upper shelf 21 is arranged on the lower shelf 22, the space utilization rate of the production site is improved.

[0047] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
