DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] See also Figures 1 to 3, which is a schematic diagram of a double-sided powder-sprinkling and thinning mechanism for fried dough sticks provided by the utility model. The double-sided powder-sprinkling and thinning mechanism for fried dough sticks comprises a conveyor frame 10; a first conveyor belt 20 and a second conveyor belt 50 arranged on the conveyor frame 10 at intervals, a vertical thinning component 40 connecting the first conveyor belt 20 and the second conveyor belt 50, and a powder sprinkler 60 arranged on the first conveyor belt 20 and the second conveyor belt 50. It can be imagined that the double-sided powder-sprinkling and thinning mechanism for fried dough sticks also includes other functional components and specific structures, such as electrical connection components, transmission components, and mounting structures, which are all technologies well known to those skilled in the art, so they will not be described in detail one by one here.

[0023] The conveying frame 10 is a frame structure with a hollow middle portion, which is convenient for assembly and installation of various components.

[0024] The first conveyor belt 20 and the second conveyor belt 50 are arranged on the conveyor frame 10, driven by respective motors, and wound on driving rollers to achieve reciprocating translation. Their structures and connections are conventional settings in the field and will not be described in detail here.

[0025] The first conveyor belt 20 is arranged at the upper end of the conveyor frame 10. In the present embodiment, the first conveyor belt 20 is in a horizontal conveying direction. The fried dough sticks are placed at the front end of the first conveyor belt 20. The surface of the fried dough sticks is pre-stained with dry flour to prevent the fried dough sticks from initially adhering to the first conveyor belt 20.

[0026] A horizontal thinning assembly 30 is provided at the upper end of the first conveyor belt 20. The first section of the dough of the fried dough sticks is conveyed on the first conveyor belt 20. After being horizontally thinned by the horizontal thinning assembly 30, the dough of the fried dough sticks enters the vertical thinning assembly 40. Specifically, the horizontal thinning assembly 30 includes a rolling frame 31, and horizontal rolling rollers 32 arranged in a circle on the rolling frame 31. Each horizontal rolling roller 32 is independently arranged and the outer wall of the horizontal rolling roller 32 protrudes from the edge of the rolling frame 31. The driving motor is connected to the rolling frame 31 to rotate, driving the multiple horizontal rolling rollers 32 located at the bottom of the rolling frame 31 to contact the upper end of the fried dough sticks. The multiple different rolling contact surfaces prevent the fried dough sticks from being squeezed and attached to the horizontal rolling rollers 32. The gaps between the horizontal rolling rollers 32 are conducive to the deformation space of the fried dough sticks. A powder spreading machine 60 is provided on both sides of the horizontal pressing component 30 in the conveying direction of the first conveyor belt 20. The powder spreading box includes a powder box for storing flour. The powder box is directly connected to the horizontal pressing component 30, or fixed to both sides of the first conveyor belt 20 by brackets provided on both sides of the powder box. The powder box is provided with a powder spreading hole and a matching valve for controlling the powder box drop switch. The powder spreading machine 60 is added before and after the horizontal pressing of the dough sticks to increase the friction coefficient of the dough sticks surface and reduce the stickiness of the dough sticks.

[0027] The vertical thinning assembly 40 is arranged at the rear end of the first conveyor belt 20 in the conveying direction. The vertical thinning assembly 40 includes a guide roller 41 which is arranged at intervals at the rear end of the first conveyor belt 20 in the conveying direction, and a rolling clamping roller 42 is arranged at the rear end of the guide roller 41. The guide roller 41 is connected to a motor to realize self-rotation. There is a gap between the guide roller 41 and the first conveyor belt 20 on the front and rear sides, and the rolling clamping roller 42, that is, the conveying guidance of the dough sticks is realized by the guide roller 41, and at the same time, the gap between the guide roller 41 and the first conveyor belt 20 forces the bottom surface of the dough sticks to be separated from the first conveyor belt 20.

[0028] In this embodiment, there are two groups of rolling and clamping rollers 42 arranged on the side of the guide tube away from the first conveyor belt 20, and the two groups of rolling and clamping rollers 42 are arranged at vertical intervals; the rolling and clamping rollers 42 are connected to the motor for rotation, and each group of rolling and clamping rollers 42 has two, and the fried dough sticks enter between the two rolling and clamping rollers 42 to complete vertical rolling, and the gap between each group of rolling and clamping rollers 42 is the required rolling thickness. The spacing between the rolling and clamping rollers 42 at the upper end is greater than the spacing between the rolling and clamping rollers 42 at the lower end. The two groups of rolling and clamping rollers 42 perform two sequential thickness rolling methods on the fried dough sticks, thereby preventing the fried dough sticks from being squeezed to both sides, and also realizing precise control of the conveying direction and the dropping point of the fried dough sticks.

[0029] The second conveyor belt 50 is arranged at the lower end of the conveyor frame 10 and can pass under the rolling clamping roller 42. A duster 60 is arranged along the conveying direction of the second conveyor belt 50 and on both sides of the vertical thinning assembly 40. The thin dough of the fried dough sticks discharged from the vertical thinning assembly 40 is received by the second conveyor belt 50 and spread on the second conveyor belt 50 for secondary conveyance.

[0030] The inclined conveying section 51 and the horizontal conveying section 52 are both provided with a powder sprinkler 60. Specifically, the powder sprinkler 60 located at the front end of the second conveyor belt 50 sprinkles powder on the surface of the second conveyor belt 50, that is, the bottom of the dough sticks are coated with powder. The powder sprinkler 60 located at the rear end of the second conveyor belt 50 sprinkles powder on the upper surface of the dough sticks after the material is dropped from the second conveyor belt 50. The secondary double-sided powder sprinkling of the second conveyor belt 50 prevents the powder sprinkling amount between the first conveyor belt 20 and the second conveyor belt 50 from affecting each other, so that the powder sprinkling on the surface of the dough sticks after being pressed is more uniform, providing good dough sticks surface conditions for the subsequent processes.

[0031] The second conveyor belt 50 includes an inclined conveying section 51 and a horizontal conveying section 52 connected to each other, and the horizontal conveying section 52 is attached to the lower end of the vertical thinning component 40. The inclined conveying section 51 is vertically spaced from the rear end of the first conveyor belt 20, so that the installation of multiple conveyor belts and components is more compact, saving equipment space. The inclined conveying section 51 provides a larger reserved installation space for the powder spreader 60, and the horizontal conveying section 52 approaches the vertical thinning component 40, reducing the height difference between the first conveyor belt 20 and the second conveyor belt 50, and improving the structural compactness of the entire production line.

[0032] The dropping point of the rolling and clamping roller 42 is located on the side of the horizontal conveying section 52 close to the inclined conveying section 51. By setting the conveying speed of the second conveyor belt 50, the conveying speed of the first conveyor belt 20, and the rotation speed of the rolling and clamping roller 42, the dough of the dough dropped to the horizontal conveying section 52 is prevented from being over-stretched or re-aggregated.
