[0002] In the production process of conventional steamed buns or dumplings and other wheaten food products, it is necessary to perform shaping operations on preliminary products such as dough. In the process of shaping the preliminary products, it is necessary to extrude and shape them, so as to preliminarily form the dough into subsequent products such as dough strips.

[0003] For example, Chinese utility model CN221430049U discloses an automatic dough rolling device, in which dough is placed on a feed conveyor belt for transportation, rolled into dough after passing through a rolling roller, and transported outward under the action of a discharge conveyor belt, thereby realizing automatic rolling of dough, with high automation efficiency, and being suitable for mass production of prefabricated noodle products.

[0004] However, the calendering device in the prior art only calenders the dough through two calendering rollers. When the dough is large, in order to ensure that the dough can pass smoothly and continuously between the two calendering rollers, it is often necessary to manually flatten the dough and then roll it through the calendering rollers, which makes the overall adaptability and processing efficiency of the calendering device low.

When the material-diverting roller rotates, the dough is gradually moved toward the direction of the spiral roller by using the strip-shaped material-diverting plate. When the spiral roller rotates, the dough is moved toward the two ends of the spiral roller by using the spiral plates, so that the dough is flattened, and it is rolled flat by the calendering roller and transported out of the hopper by the belt conveyor mechanism.

[0008] As a preferred technical solution of the present invention, both ends of the material-digging roller and the spiral roller are connected to a material-digging disk, and one side of the material-digging disk is in contact with the inner wall of the material hopper.

[0009] As a preferred technical solution of the present invention, the circumferential surface of the material-diverting disc is evenly distributed with teeth and grooves.

[0010] As a preferred technical solution of the present invention, the strip-shaped material-diverting plate is provided with tooth-shaped notches evenly distributed along the length direction.

[0011] As a preferred technical solution of the present invention, the material-digging roller is provided with a through slot, and a rectangular plate is inserted through the through slot.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] See also Figures 1 to 3 As shown, the present invention is a dough feeding machine, comprising a frame 1, connected to a belt conveyor mechanism 2 via the frame 1, a hopper 101 fixedly connected above the belt conveyor mechanism 2, and a feeding roller 3, a spiral roller 4, and a calendering roller 5, which are arranged in sequence along the conveying direction, being rotatably connected thereto. Furthermore, the frame 1 is connected to a receiving tray 105 located below the discharge end of the belt conveyor mechanism 2, so that the dough is received by the receiving tray 105 after calendering.

[0035] like Figure 5 and 6 As shown, the lower end of the hopper 101 is open and abuts against the conveyor belt of the belt conveyor mechanism 2. A discharge port is provided on one side wall. The feeding roller 3, spiral roller 4, and calendering roller 5 are all located within the hopper 101 and are each connected to a drive device 6. The drive device 6 includes a motor and a reducer connected to each other.

[0036] Specifically, the frame 1 is connected to three pairs of adjustable bearing blocks 102. The ends of the feed roller 3, spiral roller 4, and calendering roller 5 are rotatably connected to each pair of adjustable bearing blocks 102. The sidewalls of the hopper 101 are provided with straight slots that are clearance-matched with the rotating shafts of the feed roller 3, spiral roller 4, and calendering roller 5. The drive unit 6 is connected to the adjustable bearing blocks 102 via a bracket. The adjustable bearing blocks 102 allow the spacing between the feed roller 3, spiral roller 4, and calendering roller 5 and the conveying surface of the belt conveyor 2 to be adjusted, thereby adjusting the degree of dough rolling.

[0037] Among them, such as Figure 6 and 7 As shown, the feed roller 3 is fixedly connected to a plurality of strip-shaped feed plates 301. For example, two strip-shaped feed plates 301 are evenly distributed along the circumference of the feed roller 3, and the length direction of the strip-shaped feed plates 301 is parallel to the axial direction of the feed roller 3. Specifically, the feed roller 3 is provided with a strip-shaped through-notch, and a rectangular plate is inserted through the through-notch and fixedly connected by welding or screws. Both sides of the rectangular plate extend out of the through-notch and are symmetrically arranged relative to the feed roller 3, thereby forming two strip-shaped feed plates 301. By inserting a rectangular plate through the feed roller 3 to form two symmetrically arranged strip-shaped feed plates 301, the overall structural strength of the strip-shaped feed plates 301 is improved.

[0038] like Figure 8 As shown, the spiral roller 4 is connected to two spiral plates 401, which extend from the middle of the spiral roller 4 to both ends, and the spiral directions of the two spiral plates 401 are opposite. The outer diameter of the spiral plates 401 is equal to or equivalent to the outermost rotation diameter of the strip-shaped material stripping plate 301.

[0039] like Figure 6 As shown, the dough is placed in the hopper 101 and is located on the left side of the material dispensing roller 3. The material dispensing roller 3 is driven to rotate by the driving device 6, and the strip material dispensing plate 301 is used to gradually move the dough toward the spiral roller 4. Since the width of the strip material dispensing plate 301 is constant, the amount of dough moved each time is fixed, so that the dough can be squeezed and moved gradually toward the spiral roller 4 in a uniform and quantitative manner, and moved to the position of the spiral roller 4 under the conveying action of the belt conveyor mechanism 2.

[0040] By rotating the spiral roller 4, the spiral blades 401 are used to push the dough toward the two ends of the spiral roller 4, so that the dough is initially flattened, and finally rolled flat by the calendering roller 5, and transported out of the hopper 101 through the belt conveyor mechanism 2 and loaded into the receiving tray 105.

[0041] Among them, the belt conveyor mechanism 2 includes idler rollers 201, and the idler rollers 201 are located directly below the calender roll 5 and below the conveyor belt, and are used to support the conveyor belt of the belt conveyor mechanism 2. Thus, when the calender roll 5 calenders the dough, the conveyor belt will not sag under the support of the idler rollers 201, ensuring more sufficient calendering of the dough and improving the calendering effect.

[0042] As a preferred embodiment, as Figures 6 to 8 shown, both ends of the feeding roller 3 and the spiral roller 4 are connected with feeding discs 302, and one side of the feeding disc 302 is attached to the inner wall of the hopper 101. Tooth grooves 303 are evenly distributed on the circumferential surface of the feeding disc 302, so that a serrated structure is formed in the circumferential direction of the feeding disc 302. The feeding disc 302 is used to block and convey the dough, avoiding the occurrence of residue at both ends of the feeding roller 3 and the spiral roller 4.

[0043] At the same time, tooth-shaped notches 304 are evenly distributed along the length direction of the strip-shaped feeding plate 301, and the tooth-shaped notches 304 are in a rectangular or V-shaped structure. When the strip-shaped feeding plate 301 presses and stirs the dough, the dough can be extruded into the tooth-shaped notches 304, so that the dough forms a uniform upward bulge, which is convenient for subsequent flattening and calendering.

[0044] In addition, the frame 1 is connected with a first scraper 103, which is used to clean the surface of the calender roll 5 through the first scraper 103, so that during the rotation of the calender roll 5, the flour or dough scraps adhered to the surface are scraped off by the first scraper 103, ensuring the smooth surface of the dough after calendering.

[0045] And the frame 1 is connected with a second scraper 104 to clean the surface of the conveyor belt of the belt conveyor mechanism 2 through the second scraper 104. The second scraper 104 is located at the position where the conveying surface of the conveyor belt rotates downward, and the second scraper 104 is located above the receiving tray 105. Thus, during the conveying process of the conveyor belt, the dough scraps on the surface of the conveyor belt are scraped off by the second scraper 104 to ensure the cleanliness of the conveyor belt surface, and the scraped dough scraps are received by the receiving tray 105. By arranging the first scraper 103 and the second scraper 104 to clean the surfaces of the calender roll 5 and the conveyor belt respectively, the overall use reliability and practicability are further improved.
