Description

Technical Field

[0001] This utility model relates to the field of bread baking machine technology, and in particular to an automatic bread baking machine with a flipping function. Background Technology

[0002] In commercial catering environments such as hotel breakfasts, buffets, Western restaurants, and fast food outlets, toasted bread is an extremely common and high-demand food item. Commercial settings have much higher requirements for toasting equipment than home settings, with core needs being high efficiency, high consistency, and high reliability. Currently, commercial kitchens typically use two types of equipment: chain-type bread toasters and multi-slot vertical bread machines.

[0003] However, while traditional chain-type bread toasters use a chain conveyor belt to uniformly transport bread slices, allowing them to continuously pass over the upper and lower heating elements for toasting, the bread slices maintain a fixed spatial orientation during transport. Each slice's surface always faces its corresponding heating element. Furthermore, due to structural limitations, the distance between the upper heating element and the upper surface of the bread slice is usually greater than the distance between the lower heating element and the lower surface. This difference in distance results in insufficient heating and lighter browning of the upper surface of the bread slice, which is further away from the upper heating element. To compensate for this uneven browning, existing equipment typically employs two methods: one is to perform a secondary toasting process, which significantly reduces the equipment's toasting efficiency; the other is to slow down the conveyor speed to extend the heating time of the upper surface of the bread slice. However, this approach increases the risk of scorching on the lower surface under continuous intense heat, ultimately making it difficult to balance toasting uniformity and efficiency. Utility Model Content

[0004] This utility model relates to an automatic flipping bread toasting machine, which solves the problem that although traditional chain-type bread toasting machines can convey bread slices at a uniform speed through a chain conveyor belt and use upper and lower heating tubes for toasting, the bread slices are in a fixed position and the upper heating tube is far away due to structural limitations, resulting in the upper surface of the bread slices being lightly browned. Secondary toasting reduces efficiency, and slowing down the conveying speed will cause the lower surface of the bread slices to burn, making it difficult to balance toasting uniformity and efficiency.

[0005] In a first aspect, this utility model provides an automatic bread-toasting machine, specifically comprising: a housing, wherein a feeding port is provided on the upper front side of the housing, and a discharging port is provided on the lower front side of the housing; two conveying mechanisms and two heating elements are installed inside the housing, a driving mechanism is provided at the bottom of the housing, and a linkage component is provided between the two conveying mechanisms; an arc-shaped guide plate and an inclined guide plate are installed on the rear side inside the housing, the arc-shaped guide plate and the inclined guide plate are fixedly connected, and the arc-shaped guide plate is located at the upper end of the inclined guide plate.

[0006] Furthermore, a support plate is fixedly connected inside the discharge port. The upper front face of the support plate has rectangular notches evenly spaced. L-shaped baffles are provided on both the left and right sides of the upper front face of the support plate, and a limit plate is provided on the upper front face of the support plate.

[0007] Furthermore, a control box and a protective cover are installed on the right end face of the enclosure.

[0008] Furthermore, the conveying mechanism includes a rotating shaft rotatably connected to the housing. Sprockets are installed at both ends of the rotating shaft, and the sprockets are located inside the housing. A chain is connected to the outside of the sprockets, and a support rod is rotatably connected to the chain. The support rod is used to support the bread slices.

[0009] Furthermore, the drive mechanism includes a drive motor and a driven pulley. The drive motor is installed at the bottom of the housing, and a drive pulley is installed on the shaft of the drive motor. The driven pulley is installed at the right end of a rotating shaft on the lower front side. The drive pulley and the driven pulley are connected by a belt drive.

[0010] Furthermore, the linkage assembly includes a linkage gear A, a linkage shaft, and a synchronous pulley B. The linkage gear A is mounted on a rotating shaft on the lower rear side. The linkage shaft is rotatably connected to the right end face of the housing. The linkage gear B and the synchronous pulley A are mounted on the outside of the linkage shaft. The linkage gear B meshes with the linkage gear A. The synchronous pulley B is mounted on a rotating shaft on the upper rear side. The synchronous pulley B and the synchronous pulley A are connected by a synchronous belt drive.

[0011] This utility model provides an automatic bread-turning baking machine, which has the following beneficial effects: 1. Through the combined design of the arc-shaped guide plate and the inclined guide plate, the bread slice is conveyed backward by the upper conveyor mechanism. Guided by the arc-shaped guide plate and the inclined guide plate, it is automatically flipped over and then conveyed forward by the lower conveyor mechanism. During this process, since the distance between the upper and lower heating elements and the bread slice is consistent, and the conveying speed of the upper and lower conveyor mechanisms is also equal, the bread slice is evenly baked on both sides, and there is no need for secondary baking. Thus, it can take into account both baking uniformity and efficiency.

[0012] Second, by setting up linkage components, only one drive motor is needed to drive two conveying mechanisms to operate synchronously in opposite directions. This design replaces the traditional multi-motor drive scheme with a low-cost mechanical structure, which not only significantly reduces the equipment manufacturing cost, but also saves the overall power consumption of the equipment.

[0013] Other advantages, objectives and features of this invention will be apparent in part from the following description, and in part from the understanding of those skilled in the art through study and practice of this invention. Attached Figure Description

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an automatic bread-turning toasting machine, comprising: a housing 1, with a feeding port 1010 on the upper front side and a discharging port 101 on the lower front side of the housing 1; two conveying mechanisms 2 and two heating elements 3 are installed inside the housing 1, a driving mechanism 4 is provided at the bottom of the housing 1, and a linkage component 5 is provided between the two conveying mechanisms 2; an arc-shaped guide plate 105 and an inclined guide plate 106 are installed on the rear side inside the housing 1, the arc-shaped guide plate 105 and the inclined guide plate 106 are fixedly connected, and the arc-shaped guide plate 105 is located at the upper end of the inclined guide plate 106; through the cooperative design of the arc-shaped guide plate 105 and the inclined guide plate 106, the bread slices can be automatically turned over. Since the distance between the upper and lower heating elements 3 and the bread slices is consistent, and the conveying speed of the upper and lower conveying mechanisms 2 is also equal, the bread slices are evenly toasted on both sides, and there is no need for secondary toasting, thus achieving both toasting uniformity and efficiency.

[0019] A support plate 102 is fixedly connected inside the discharge port 101. A rectangular notch 107 is evenly opened on the front side of the upper end face of the support plate 102. L-shaped baffles 108 are provided on both the left and right sides of the upper end face of the support plate 102. A limit plate 109 is provided on the front side of the upper end face of the support plate 102 to support and limit the bread slices baked on both sides.

[0020] A control box 103 and a protective cover 104 are installed on the right end face of the housing 1. The front protective cover 104 is located outside the driving pulley 402 and the driven pulley 403 and is used to protect the driving pulley 402 and the driven pulley 403. The rear protective cover 104 is located outside the linkage assembly 5 and is used to protect the linkage assembly 5.

[0021] The conveying mechanism 2 includes a rotating shaft 201, which is rotatably connected to the housing 1. Sprockets 202 are installed at both ends of the rotating shaft 201. The sprockets 202 are located inside the housing 1. A chain 203 is connected to the outside of the sprockets 202. A support rod 204 is rotatably connected to the chain 203. The support rod 204 is used to support the bread slices. The upper conveying mechanism 2 is used to convey the bread slices backward, and the lower conveying mechanism 2 is used to convey the bread slices forward.

[0022] The drive mechanism 4 includes a drive motor 401 and a driven pulley 403. The drive motor 401 is installed at the bottom of the housing 1. The drive pulley 402 is installed on the shaft of the drive motor 401. The driven pulley 403 is installed at the right end of a rotating shaft 201 on the lower front side. The drive pulley 402 and the driven pulley 403 are connected by belt drive. The drive mechanism 4 is used to drive the two conveying mechanisms 2 to operate.

[0023] Example 2, based on Example 1, such as Figure 5As shown, the linkage assembly 5 includes a linkage gear A501, a linkage shaft 502, and a synchronous pulley B505. The linkage gear A501 is mounted on a rotating shaft 201 on the lower rear side. The linkage shaft 502 is rotatably connected to the right end face of the housing 1. A linkage gear B503 and a synchronous pulley A504 are mounted on the outside of the linkage shaft 502. The linkage gear B503 meshes with the linkage gear A501. The synchronous pulley B505 is mounted on a rotating shaft 201 on the upper rear side. The synchronous pulley B505 and the synchronous pulley A504 are connected by a synchronous belt drive. With the setting of the linkage assembly 5, only one drive motor 401 is needed to drive the two conveying mechanisms 2 to operate synchronously in opposite directions, which not only reduces the equipment manufacturing cost, but also effectively saves the overall power consumption of the equipment.

[0024] The working principle of this embodiment is as follows: During baking, the two heating elements 3 are first started by the control box 103, so that the two heating elements 3 start to heat up. Then, the drive motor 401 is started by the control box 103. The drive motor 401 drives the driving pulley 402, the driven pulley 403, the lower front rotating shaft 201 and the lower front sprockets 202 to rotate counterclockwise, thereby driving the lower chain 203 and the corresponding support rod 204 to rotate counterclockwise. Then, the lower rear rotating shaft 201 drives the linkage gear A501 to rotate counterclockwise. The linkage gear B503 drives the linkage shaft 502, the synchronous pulley A504 and the synchronous pulley B505 to rotate clockwise, thereby driving the upper rear rotating shaft 201 and the upper rear sprockets 202 to rotate clockwise, thereby driving the upper chain 203 and the corresponding support rod 204 to rotate clockwise. Next, the bread slices to be baked are placed on the upper support rod 204 through the feeding port 1010. The upper support rod 204, driven clockwise, conveys the bread slices backward. During the conveying process, the lower surface of the bread slices faces the upper heating element 3, and the lower surface of the bread slices is baked. The baked bread slices fall downward through the rear end of the upper conveyor mechanism 2. Then, under the guidance of the arc guide plate 105 and the inclined guide plate 106, the baked bread slices are automatically flipped over. Then, they are conveyed forward through the lower conveyor mechanism 2, at which point the upper surface of the bread slices faces down. The lower heating element 3 then bakes the current lower surface of the bread slices. Since the distance between the two heating elements 3 and the upper and lower surfaces of the bread slices is the same, and the conveying speed of the two conveyor mechanisms 2 is also equal, the uniformity of baking on both sides of the bread slices is improved, and there is no need for secondary baking, ensuring high baking efficiency. After the upper and lower sides of the bread slices are baked, they are conveyed to the support plate 102 and finally removed.
