Description

Technical Field

[0001] This utility model relates to the technical field of pasta processing machinery and equipment, specifically a double-powder-sprinkling dough shaping machine. Background Technology

[0002] Handmade dough sheets are characterized by their soft, sticky texture and delicate taste. However, during mechanical processing, their high stickiness makes them prone to adhering to conveyor belts or pressing rollers, leading to dough sheet damage, deformation, or downtime for cleaning, thus affecting production efficiency and product appearance quality. Existing dough sheet shaping equipment typically only has a powdering device at a single station, offering limited anti-sticking effectiveness and failing to meet the continuous production demands of highly sticky dough sheets. Therefore, there is an urgent need for a shaping device that can effectively prevent dough sheet adhesion and ensure continuous and stable production. Utility Model Content

[0003] This invention aims to solve the problem of dough sticking together, which affects production continuity and product quality in the prior art. It provides a double-powder-sprinkling dough shaping machine, which achieves double anti-sticking treatment for the belt and dough by setting powder-sprinkling mechanisms at the front and rear workstations respectively.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a double-powder dough shaping machine, comprising: The feed belt assembly is located on the upper side of one end of the frame and is used to feed the dough sheets; The dough pressing roller assembly is located at the outlet end of the feed belt assembly and is used to press the dough to a set thickness. The discharge belt assembly is located below the discharge port of the feed belt assembly and below the pressing roller assembly; The pre-powdering mechanism is located at the inlet end of the discharge belt assembly and upstream of the dough pressing roller assembly. It is used to sprinkle powder on the upper side of the belt before the discharge belt assembly receives the dough. The dividing blade assembly is located in the middle of the discharge belt assembly and is used to cut the dough to a set width. The rear powder-spreading mechanism is located at the outlet end of the discharge belt assembly and is used to spread powder on the upper side of the dough.

[0005] Furthermore, the feed belt assembly, the pressing roller assembly, and the discharge belt assembly are all driven by independent power mechanisms, and the speeds of the three power mechanisms are matched during operation to adapt to the processing needs of dough with different degrees of softness and hardness.

[0006] Furthermore, the front powder-spreading mechanism and the rear powder-spreading mechanism have similar structures but different sizes; the front powder-spreading mechanism is fixed on the rear end face of the pressing roller assembly bracket, and the rear powder-spreading mechanism spans across the discharge belt assembly.

[0007] Furthermore, the rear powder-spreading mechanism includes a crossbeam support, a rotating shaft, a powder-spreading motor, a powder-spreading hopper, a powder-spreading roller, and a screen. The crossbeam support spans the frame of the discharge belt assembly, and the powder-spreading hopper is horizontally fixed on the crossbeam support, with its length adapted to the belt width of the discharge belt assembly. The powder-spreading motor is fixed to one end of the outer side of the powder-spreading hopper, and its output shaft is poweredly connected to one end of the rotating shaft. The other end of the rotating shaft passes through the lower part of the powder-spreading hopper and is movably connected to the other side of the powder-spreading hopper. The powder-spreading roller is fixedly mounted on the rotating shaft located inside the powder-spreading hopper. The screen is located on the bottom side of the powder-spreading hopper and directly below the powder-spreading roller.

[0008] Furthermore, the side of the powder-spreading roller is provided with a row or discretely distributed brush; the top of the powder-spreading hopper is provided with an openable and closable cover plate.

[0009] Furthermore, the dividing blade assembly includes a cutting disc and a paddle; both the cutting disc and the paddle are movably mounted on a laterally adjustable dividing blade support, which spans the frame of the discharge belt assembly; the height between the cutting disc and the discharge belt assembly is adjustable to adjust the cutting force; the cutting disc is movably mounted on the blade holder without power, and its rotation is driven by the movement of the dough to achieve cutting; one end of the paddle is close to the cutting disc, and the other end is bent outward to discharge excess dough to the outside of the discharge belt assembly.

[0010] Compared with existing technologies, this invention offers the following advantages: By employing a front- and rear-mounted dual powder-sprinkling mechanism, powder is sprinkled onto both the belt surface and the dough surface, significantly reducing the adhesion of highly viscous dough during processing. Each drive component is independently controlled and its speed is adjustable, adapting to dough of varying textures and hardness, thus improving the equipment's versatility and process adaptability. The dividing blade assembly utilizes a non-powered cutter disc and an adjustable paddle structure, ensuring smooth cutting and easy removal of edge material, guaranteeing the accuracy of dough width and edge neatness. The overall structure of this invention is rationally laid out, easy to operate and maintain, and suitable for continuous and automated production needs. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figures 1-5 As shown, this utility model discloses a double-powder-sprinkling dough sheet shaping machine, including a frame 7 and, according to the process, an infeed belt assembly 1, a pressing roller assembly 2, an outlet belt assembly 3, a pre-powder-sprinkling mechanism 4, a dividing knife assembly 5, and a rear-powder-sprinkling mechanism 6 arranged on it. The infeed belt assembly 1 is used to guide the dough sheet into the equipment; the pressing roller assembly 2 is used to roll the dough sheet to a set thickness; the outlet belt assembly 3 receives the rolled dough sheet and continues to transport it; the pre-powder-sprinkling mechanism 4 sprinkles powder on the surface of the belt before the dough sheet enters the outlet belt assembly 3 to prevent the dough sheet from sticking to the belt; the dividing knife assembly 5 longitudinally cuts the dough sheet during the transport process to obtain a set width; the rear-powder-sprinkling mechanism 6 sprinkles powder on the upper surface of the dough sheet before it is output to prevent it from sticking during subsequent stacking or rolling.

[0020] In this invention, the feed belt assembly 1 is inclinedly positioned on the upper side of one end of the frame 7 to receive and guide the dough to be shaped. The pressing roller assembly 2 is located at the outlet end of the feed belt assembly 1 and consists of one or more pairs of relatively rotating pressing rollers. The pressing thickness of the dough is controlled by adjusting the gap between the rollers. The discharge belt assembly 3 is horizontally positioned below the pressing roller assembly 2 to receive the pressed dough and continue to transport it forward.

[0021] The pre-spreading flour mechanism 4 is installed on the rear end face of the support of the dough roller assembly 2 and is located above the feed inlet of the discharge belt assembly 3. Its structure can be referred to as the rear-spreading flour mechanism 6, mainly including a hopper, a flour spreading roller, and a screen. During operation, the pre-spreading flour mechanism 4 spreads flour evenly on the surface of the discharge belt assembly 3 before the dough arrives, forming an isolation layer.

[0022] The dividing blade assembly 5 is mounted horizontally above the middle of the discharge belt assembly 3 via the dividing blade bracket 53. The cutting disc 51 is mounted via the blade holder 54, and its height is adjustable to control the cutting depth. The cutting disc 51 is non-powered, relying on the friction of the moving dough to rotate and achieve longitudinal cutting of the dough. The paddle 52 is mounted on one side of the cutting disc 51, and its bent end can guide the cut edge material to the outside of the belt.

[0023] The rear-mounted powder-spreading mechanism 6 is mounted transversely above the outlet end of the discharge belt assembly 3 via a crossbeam bracket 61. The powder-spreading motor 63 drives the rotating shaft 62 and the powder-spreading roller 65 fixed thereon to rotate. The brushes 67 circumferentially arranged on the powder-spreading roller 65 evenly sift the flour in the hopper 64 through the bottom mesh screen 66 onto the surface of the dough passing below, completing the secondary powder spreading. The cover plate 68 is used to seal the hopper, preventing dust spillage and facilitating powder addition.

[0024] The feed belt assembly 1, the pressing roller assembly 2, and the discharge belt assembly 3 are each driven by an independent motor. The speed of the three is coordinated by the control system to ensure that the dough has appropriate tension during processing and does not stretch, deform, or accumulate.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
