Description

Technical Field

[0001] The invention belongs to the field of rice noodle sheet spreading, and in particular relates to a rice noodle sheet spreading method and a spreading mechanism based on the principle of a gear pump. Background Art

[0002] During the production process of starch products (especially vermicelli), the prepared slurry is injected into the slurry storage tank, and the slurry is wrapped and brought out to form a layer through a shaping roller by using the viscosity of the slurry, and then sent to the conveyor steel belt and sent to the steaming process (for example, application number CN2016206543078, sweet potato vermicelli rapid aging device). In this process, since the slurry is not uniform (that is, the dilution and viscosity of each part of the slurry are different), the amount of slurry wrapped on the shaping roller at every moment will be quite different, resulting in uneven thickness of the vermicelli produced.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0018] In the present invention, unless otherwise clearly stipulated and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] As attached Figure 1-3 As shown, a rice noodle slurry spreading method based on the gear pump principle is as follows: the raw materials are passed through the gear pump 2, so that the feed port of the gear pump 2 feeds the raw materials evenly along the width direction of the gear; and after the raw materials are discharged from the discharge port of the gear pump 2, they are kept evenly along the width direction of the gear.

[0020] The present invention utilizes the good quantitative effect of the gear pump. Therefore, in order to ensure the accuracy of quantitative measurement, on the one hand, the feeding at the feeding port of the gear pump 2 is uniform, so as to ensure that the discharge is uniform at every point along the width direction during discharge; on the other hand, in order to ensure that the thickness of the produced rice noodle skin is uniform, the raw materials are kept uniform along the width direction of the gear after being discharged from the feeding port of the gear pump 2.

[0021] To achieve the above-mentioned effects, specifically, a rice noodle spreading mechanism based on the gear pump principle includes a gear pump 2, and a discharge plate 6 matching the width of the gears in the gear pump 2 is arranged at the discharge port of the gear pump 2. Specifically, "matching" means that the width of the gears in the gear pump 2 is preferably equal to the width of the discharge plate 6, or the width error is controlled within ±5mm, and the left and right ends of the discharge plate 6 are bent upward to form a limit, so that the material discharged from the gear pump 2 can be received and kept uniform.

[0022] Furthermore, a slurry pool 3 is arranged at the feed inlet of the gear pump 2, and the minimum width of the slurry pool 3 along the gear axis direction is not less than the gear width in the gear pump 2. The slurry pool 3 at least satisfies the requirement that the width at the feed inlet of the gear pump 2 is greater than the gear width in the gear pump 2, and in actual use, it is ensured that there is sufficient slurry in the slurry pool 3 so that the gear pump 2 can be fully fed with slurry.

[0023] The gear width can be 200mm~2500mm depending on the production scale, and is generally 800mm~1800mm in the actual production line. The gear speed is controlled at 0~100 rpm, and is generally 30~70 rpm in the actual production line.

[0024] Furthermore, it also includes a frame 1, and the gear pump 2 is fixed to the frame 1; the gear pump 2 includes two mounting plates 20, the two mounting plates 20 are fixedly connected to the frame 1, and the first gear shaft 21 and the second gear shaft 22 are rotatably connected between the two mounting plates 20, and the first gear shaft 21 and the second gear shaft 22 are meshed; the first gear shaft 21 is connected to the rotation driving mechanism 23, and a C-shaped baffle 24 is respectively arranged outside the first gear shaft 21 and the second gear shaft 22, and the gaps on the front and rear sides between the two C-shaped baffles 24 respectively form the feed port and the discharge port of the gear pump 2, and the two ends of the C-shaped baffle 24 are respectively fixedly connected to a mounting plate 20. The relationship between the C-shaped baffle 24 and the gear shaft refers to the relationship between the shell and the gear in the traditional gear pump, and the gap between the two is extremely small, and the slurry has viscosity (not water), and a small gap will not leak down, so that the slurry can be transported between the tooth groove and the C-shaped baffle 24.

[0025] The plane formed between the axes of the first gear shaft 21 and the second gear shaft 22 preferably forms an angle of 10°~30° with the vertical plane, that is, the gear pump 2 is tilted so that the slurry pool 3 relies on gravity to feed the gear pump 2 obliquely downward, and the slurry is discharged from the gear pump 2 obliquely downward.

[0026] Both ends of the first gear shaft 21 and the second gear shaft 22 are connected to the mounting plate 20 through bearings.

[0027] Furthermore, the rotation drive mechanism 23 includes a drive motor 231, the output end of the drive motor 231 is fixedly connected to one end of the motor reducer 232, the other end of the motor reducer 232 is fixedly connected to the first driving sprocket 233, the drive motor 231 and the motor reducer 232 are both fixedly connected to the frame 1, and the first driving sprocket 233 is connected to the first driven sprocket 234 through a chain; one end of the first gear shaft 21 extends from the mounting plate 20 and is fixedly connected to the first driven sprocket 234.

[0028] Furthermore, a channel steel 25 is arranged outside the C-shaped baffle plate 24, and two ends of the channel steel 25 are respectively fixedly connected to a mounting plate 20, and screw holes 251 are arranged in an array on both sides of the channel steel 25 along the length direction, and the screw holes 251 are arranged toward the outer surface of the C-shaped baffle plate 24; the functions of the channel steel 25: on the one hand, it is mainly used to enhance the strength of the whole machine, and on the other hand, through the screw holes 251 arranged in an array, the screws passed through the screw holes 251 abut against the outer surface of the C-shaped baffle plate 24, so as to prevent the partial deformation of the C-shaped baffle plate 24 during long-term use, and serve as an auxiliary support.

[0029] Further, as attached Figure 1-4 As shown, it also includes a stirring mechanism 4, wherein the stirring mechanism 4 includes a second driving sprocket 401 that extends from the mounting plate 20 at one end of the second gear shaft 22 and is fixedly connected, the second driving sprocket 401 is connected to the second driven sprocket 402 through a chain, the second driven sprocket 402 is fixedly connected to one end of the first rotating shaft 41, and the first support plate 252, the second support plate 253, and the third support plate 254 are fixedly connected in sequence in the lateral extension direction of the pulp pool 3, and the first support plate 252, the second support plate 253, and the third support plate 254 can also be further fixedly connected to the top channel steel 25; the other end of the first rotating shaft 42 passes through the first support plate 252 and the second support plate 253 in sequence and is fixedly connected to the driving gear 411, and the first rotating shaft 41 is rotatably connected to the first support plate 252 and the second support plate 253, and is preferably rotatably connected through a bearing; A second rotating shaft 42 is arranged between the second supporting plate 253 and the third supporting plate 254. The second rotating shaft 42 is rotatably connected to the second supporting plate 253 and the third supporting plate 254, and is preferably rotatably connected via a bearing. The second rotating shaft 42 is fixedly connected to a driven gear 421 meshing with the driving gear 411. Two ends of the second rotating shaft 42 extend from the second supporting plate 253 and the third supporting plate 254, respectively, and are fixedly connected to one end of a short arm 43, respectively. The other end of the short arm 43 is rotatably connected to the first connecting rod. 44, the other end of the first connecting rod 44 is rotatably connected to one end of the second connecting rod 45, the other end of the second connecting rod 45 extends into the pulp pool 3, and the ends of the two second connecting rods 45 extending into the pulp pool 3 are fixedly connected to the shifting rod 46, and the rod body of the second connecting rod 45 is rotatably connected to the side wall of the pulp pool 3; the short arm 43, the first connecting rod 44, and the second connecting rod 45 form a three-link mechanism, wherein the length of the short arm 43 mainly determines the swing amplitude of the shifting rod 46, so the length of the short arm 43 is generally not greater than 1 / 2 of the width at the feed inlet of the gear pump 2.

[0030] The gear pump 2 and the stirring mechanism 4 share a driving system.

[0031] Different from the transmission slurry spreading, in which the shaping roller floats on the surface of the slurry pool to shape the slurry, in this scheme the slurry enters the feed port by gravity, so the lever 46 is extended into the slurry pool 3 for stirring, so that the slurry around the feed port remains mobile and does not condense on the board surface, while maintaining a good slurry feeding effect.

[0032] Further, as attached Figure 5-6 As shown, it includes a sizing mechanism, which is a gear pump 2 in this application. A discharge plate 6 is arranged at the discharge port of the sizing mechanism. A guide mechanism 5 is arranged below the discharge plate 6. The guide mechanism 5 includes a rotatable guide plate 54. The guide plate 54 can be rotated to make the guide plate 54 tilt downward away from the front end of the discharge plate 6, that is, as shown Figure 1 , in a normal feeding state, or tilted downward near the rear end of the discharge plate 6, that is, Figure 6 , in a shutdown state, a waste liquid tank 7 is arranged below the rear end of the discharge plate 6; the guide mechanism 5 is also provided with an adjustment structure that can adjust the angle of the guide plate 54.

[0033] Further, a guide mechanism 5 is provided below the discharge plate 6, and the guide mechanism 5 includes two positioning plates 51, the positioning plates 51 are fixedly connected to the frame 1, and strip grooves 511 are provided on the positioning plates 51, and also includes a support rod 52, and the two ends of the support rod 52 are respectively arranged in the strip grooves 511 of the two positioning plates 51, and also includes an adjustment plate 53, and the adjustment plate 53 is provided with a through hole for the support rod 52 to pass through, and a strip hole 531, and the strip hole 531 is arranged in parallel with the strip groove 511, and a bolt passes through the strip groove 511. The holes 531 and the positioning plate 51 are fixed between the positioning plate 51 and the adjustment plate 53; the support rod 52 is fixedly connected to the guide plate 54, which is arranged below the discharge plate 6, and the top of the guide plate 54 abuts against the bottom of the discharge plate 6, so that by loosening the bolts, the adjustment plate 53 can move forward and backward through the strip holes 531, and at the same time, the support rod 52 can be moved forward and backward to adjust the position of the guide plate 54 to change the angle of the guide plate 54 to meet the spacing between the guide plate 54 and the steel belt that receives the rice noodle skin below. (The guide plate 54 can be flipped, and when it is flipped to this position when the machine is stopped, the material can be quickly cut off, and then the pulp pool 3 is cleaned to discharge the waste water into the waste liquid tank 7, which is convenient for collecting waste).

[0034] Furthermore, at least one end of the support rod 52 is fixedly connected to a handle 521 for manually controlling the guide plate 54 to rotate and cut materials when the machine is shut down.

[0035] Furthermore, a waste liquid tank 7 is arranged below the gear pump 2 and the pulp pool 3 , a drainage hole 71 is arranged behind the waste liquid tank 7 , and the waste liquid tank 7 is fixedly connected to the frame 1 .

[0036] When in use, ensure that there is enough slurry in the slurry pool 3, at least to cover the tooth width of the second gear shaft 22, start the driving motor 231, and the driving motor 231 drives the first active sprocket 233 to rotate through the motor reducer 232. The first active sprocket 233 drives the first driven sprocket 234 to rotate through the chain, so that the first gear shaft 21 rotates, and the meshing second gear shaft 22 rotates at the same time. The slurry is continuously brought out by the gear pump 2. After the slurry is discharged from the discharge port of the gear pump 2, it remains uniform along the width direction and falls into the discharge plate 6 with matching width to form a layered structure; Furthermore, the rotation of the second gear shaft 22 causes the second driving sprocket 401 to rotate, and the second driving sprocket 401 drives the second driven sprocket 402 to rotate through the chain, so that the driving gear 411 rotates synchronously, and the driving gear 411 drives the meshing driven gear 421 to rotate, so that the second rotating shaft 42 drives the short arm 43 to rotate, and in turn pulls the first connecting rod 44 and the second connecting rod 45. The second connecting rod 45 itself forms a lever mechanism, so that the lever 46 continues to swing in the pulp pool 3, keeping the pulp around the feed port moving and not condensing on the board surface, while maintaining a good pulp feeding effect.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
