The driving assembly 300 is connected to the second support frame 210 to drive the second support frame 210 to rotate relative to the first support frame 110 and simultaneously drive the first support frame 110 to rotate. The receiving and conveying device 600 has two states, i.e. a working state and a non-working state. Figure 6 As shown, the working state, Figure 7 As shown, the non-working state. In the working state, the driving assembly 300 drives the second conveying assembly 200 to be in an unfolded state as shown, and at this time, the first belt 130 and the second belt 230 are basically in a parallel state. The head of the dough sheet pressed by the front dough sheet pressing roller set 400 falls on the first belt 130. The first roller set drives the first belt 130 to convey. The first belt 130 conveys the head of the dough sheet to the second belt 230. The second belt 230 conveys the head of the dough sheet to the rear dough sheet pressing roller set 500 under the action of the first roller set, i.e. the receiving and conveying device 600 completes the work of receiving the dough sheet. Figure 6 As shown, the non-working state. In the working state, the driving assembly 300 drives the second conveying assembly 200 to be in an unfolded state as shown, and at this time, the first belt 130 and the second belt 230 are basically in a parallel state. The head of the dough sheet pressed by the front dough sheet pressing roller set 400 falls on the first belt 130. The first roller set drives the first belt 130 to convey. The first belt 130 conveys the head of the dough sheet to the second belt 230. The second belt 230 conveys the head of the dough sheet to the rear dough sheet pressing roller set 500 under the action of the first roller set, i.e. the receiving and conveying device 600 completes the work of receiving the dough sheet. Figure 7 As shown, the non-working state. In the working state, the driving assembly 300 drives the second conveying assembly 200 to be in an unfolded state as shown, and at this time, the first belt 130 and the second belt 230 are basically in a parallel state. The head of the dough sheet pressed by the front dough sheet pressing roller set 400 falls on the first belt 130. The first roller set drives the first belt 130 to convey. The first belt 130 conveys the head of the dough sheet to the second belt 230. The second belt 230 conveys the head of the dough sheet to the rear dough sheet pressing roller set 500 under the action of the first roller set, i.e. the receiving and conveying device 600 completes the work of receiving the dough sheet.

[0030] Through cooperation between the first transmission assembly 100, the second transmission assembly 200 and the driving assembly 300, on the one hand, the dough sheet pressed by the front dough roller set 400 can be automatically received and transported to the rear dough roller set 500, that is, the function of automatic transmission of the dough sheet between the front dough roller set 400 and the rear dough roller set 500 is realized; on the other hand, after receiving the dough sheet, the driving assembly 300 can make the first transmission assembly 100 and the second transmission assembly 200 sink, so that the mutual sticking of the dough sheet and the belt due to long-time contact is avoided, and the quality problem of the dough sheet caused by friction is reduced. Therefore, the automatic dough sheet receiving and delivering device in the application realizes the operation of automatically receiving the dough sheet, without manual intervention, effectively reduces the labor intensity of the operator, and improves the production efficiency and the quality of the product.

[0031] As shown in Figure 1 The first roller set includes an electric roller 120 and a first roller 121, both of which are rotatably installed on the first support frame 110, and the first belt 130 is sleeved on the electric roller 120 and the first roller 121. The second roller set includes a second roller 220, which is rotatably installed on the second support frame 210, and the second belt 230 is sleeved on the electric roller 120 and the second roller 220.

[0038] Optionally, a plurality of first belts 130 are arranged on the first roller group, and the first belts 130 are arranged in parallel and are spaced from each other. A plurality of second belts 230 are arranged on the second roller group, and the second belts 230 are arranged in parallel and are spaced from each other. The first belts 130 and the second belts 230 are PU belts. The PU belt, that is, the polyurethane belt, does not stick to the surface sheet. The first belt 130 and the second belt 230 are arranged as several narrow belts instead of a wide belt, which can further reduce the contact area between the belt and the surface sheet and reduce the risk of damage to the surface sheet. The traditional wide flat belt is heavy and difficult to clean.

[0039] It should be noted that, for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
