A conveying device and conveying method for macaroni production

Abstract

This invention relates to the field of conveying device technology, and discloses a conveying device and method for macaroni production. Through the arrangement of a powder-spreading component and a powder storage box, during the process of conveying macaroni from the loading end to the unloading end by an electric conveyor belt, the powder storage box delivers flour to the powder-spreading head of the powder-spreading component. The powder-spreading head, through the processing of the upper and lower grinding plates, crushes any lumps of flour and discharges them along with the finer flour particles through the gap between the upper and lower grinding plates. The powder is then evenly spread onto the macaroni by the powder-spreading head. Simultaneously, the reciprocating powder-spreading head drives the kneading plate to move synchronously, causing the kneading plate to knead the flour-spreaded macaroni and roll it on the conveyor belt, ensuring the surface of the macaroni is fully coated with flour. This allows the flour to absorb moisture from the macaroni, reducing its viscosity and effectively preventing it from sticking to the electric conveyor belt during transport, thereby improving the conveying efficiency of the macaroni.

Description

Technical Field

[0001] This invention relates to the field of conveying device technology, specifically to a conveying device and conveying method for macaroni production. Background Technology

[0002] Macaroni is a tubular pasta dish originating from Italy, made from durum wheat flour and water. It is usually hollow and short or curved in shape. It is a type of pasta with a firm texture that can withstand cooking. It is suitable for pairing with rich sauces or for use in baked dishes. It is one of the most common ingredients in the world. The production process of macaroni mainly includes the steps of raw material preparation, dough mixing, shaping, drying and packaging.

[0003] After the macaroni is formed, it usually needs to be transported to a drying box by a conveyor device for drying. During this process, because the freshly extruded macaroni contains moisture and has a certain degree of stickiness, the moisture-containing macaroni will stick to the conveyor belt when it is transported by the conveyor device. As a result, after the conveyor belt transports the macaroni to the unloading end, it is necessary to manually clean the macaroni stuck to the conveyor belt, which reduces the conveying efficiency of the macaroni. Summary of the Invention

[0011] Preferably, a screen is fixedly installed at the bottom of the powder-spreading head, the screen being located below the lower grinding plate. A connecting plate is provided on the side of the powder-spreading head facing the discharge end. Fixed rods are fixedly connected to both sides of the connecting plate, and the upper ends of the two fixed rods are respectively fixedly connected to both sides of the powder-spreading head.

[0016] The present invention also provides a conveying method, which uses a conveying device for macaroni production, the specific steps of which are as follows:

[0017] First, the electric conveyor belt transports the macaroni from the loading end to the unloading end. The powder storage box then delivers the flour to the powder spreading head. The powder spreading head reciprocates above the electric conveyor belt, evenly spreading the flour onto the macaroni. Simultaneously, the spreading head drives the powder rolling plate to move synchronously, causing the flour-coated macaroni to roll on the electric conveyor belt, ensuring the surface of the macaroni is fully coated with flour and preventing it from sticking to the electric conveyor belt during transport. After the macaroni is unloaded from the unloading end, the remaining flour on the electric conveyor belt is collected by the powder collection component and transported to the powder storage box for reuse.

[0018] Compared with the prior art, the present invention provides a conveying device and conveying method for macaroni production, which has the following beneficial effects:

[0019] 1. The conveying device and method for macaroni production, through the setting of a powder-spreading component and a powder storage box, during the process of conveying macaroni from the feeding end to the unloading end by an electric conveyor belt, the powder storage box conveys the flour inside to the powder-spreading head of the powder-spreading component. The powder-spreading head, through the processing of the upper and lower grinding plates, crushes the lumps of flour in the flour and discharges it together with the fine flour through the gap between the upper and lower grinding plates. Then, the powder-spreading head evenly sprinkles it on the macaroni. At the same time, the reciprocating powder-spreading head drives the kneading plate to move synchronously, so that the kneading plate kneads the flour-spreaded macaroni and rolls it on the conveyor belt, so that the surface of the macaroni is fully coated with flour. In this way, the flour absorbs the moisture in the macaroni, reducing the viscosity of the macaroni. This effectively prevents the macaroni from sticking to the electric conveyor belt during the conveying process, thereby improving the conveying efficiency of the macaroni.

[0020] 2. The conveying device and method for macaroni production, through the setting of the powder collection component, after the macaroni is sent out from the discharge end by the electric conveyor belt, most of the remaining flour on the electric conveyor belt will fall directly into the collection hopper, while the other part of the flour will stick to the electric conveyor belt and continue to move with the electric conveyor belt. At this time, the powder scraper against the electric conveyor belt will scrape off the flour stuck to the electric conveyor belt and collect it in the collection hopper, thereby cleaning the electric conveyor belt. The flour collected in the collection hopper will be conveyed by the conveying pump and re-enter the powder storage box, so that the remaining flour can be reused, avoiding flour waste and reducing the production cost of macaroni.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-12 A conveying device for macaroni production includes a mounting frame 1, an electric conveyor belt 2, a powder-spreading assembly 3, a powder storage box 4, and a powder-collecting assembly 5. The electric conveyor belt 2 is rotatably mounted on the mounting frame 1 and is used to convey macaroni from the feeding end 11 of the mounting frame 1 to its unloading end 12. The powder-spreading assembly 3 includes a fixed frame 31, a powder-spreading head 32, and a powder-rubbing plate 35. The powder-spreading head 32 is movably mounted on the feeding end 11.

[0036] When conveying macaroni, the powder-sprinkling head 32 reciprocates between the two sides of the mounting frame 1 to sprinkle flour. The rubbing plate 35 is connected to the side of the powder-sprinkling head 32 facing the discharge end 12 and is close to the upper surface of the electric conveyor belt 2. When the powder-sprinkling head 32 moves, it drives the rubbing plate 35 to move synchronously, so that the rubbing plate 35 rubs the macaroni and rolls it on the electric conveyor belt 2 to coat it with flour.

[0037] The flour storage box 4 is located outside the mounting frame 1 to store flour and convey the flour to the flour spreading head 32. The flour collection component 5 is located below the discharge end 12 to collect the remaining flour on the electric conveyor belt 2 and convey the collected flour to the flour storage box 4.

[0038] In operation, the electric conveyor belt 2, driven by a motor, transports the macaroni from the loading end 11 to the unloading end 12. During this process, the powder storage box 4 transfers the flour inside to the powder-spreading head 32. The powder-spreading head 32 drives the powder-rubbing plate 35 to reciprocate horizontally between the two sides of the mounting frame 1. The reciprocating powder-spreading head 32 evenly sprinkles fine flour onto the macaroni on the electric conveyor belt 2. As the electric conveyor belt 2 continues to rotate, the flour-spreading macaroni passes under the powder-rubbing plate 35. At this time, the powder-rubbing plate, which moves synchronously with the powder-spreading head 32, passes under the powder-rubbing plate 35. The 35 motor will agitate the macaroni as it rolls on the electric conveyor belt 2, ensuring that the surface of the macaroni is fully coated with flour. This allows the flour to absorb moisture from the macaroni, reducing its stickiness and preventing it from adhering to the electric conveyor belt 2 during transport. After the electric conveyor belt 2 transports the macaroni to the unloading end 12, the flour remaining on the electric conveyor belt 2 will be collected by the flour collection component and transported back to the flour storage box 4. This allows excess flour to be reused, thereby reducing flour consumption and saving on macaroni production costs.

[0039] Furthermore, the powder-spreading assembly 3 also includes a fixing frame 31, which is fixedly connected to the feeding end 11 of the mounting frame 1. The fixing frame 31 has a sliding groove 311, and a bearing seat 312, a slide rail 313 and a servo motor 314 are fixedly connected to the fixing frame 31 in sequence. The bearing seat 312 is located at one end of the sliding groove 311, the two slide rails 313 are located on both sides of the sliding groove 311, and the servo motor 314 is located at the other end of the sliding groove 311. The output shaft of the servo motor 314 is coaxially fixedly connected to one end of the lead screw 315, and the other end of the lead screw 315 is rotatably mounted on the bearing seat 312.

[0040] When sprinkling macaroni onto the electric conveyor belt 2, the servo motor 314 drives the powder-sprinkling head 32 to reciprocate on the fixed frame 31 by rotating the lead screw 315 in both directions.

[0041] Furthermore, an upper grinding plate 321 is fixedly connected inside the powder dispensing head 32. The upper grinding plate 321 has a powder inlet 3211. A drive motor 322 is fixedly installed on the end of the upper grinding plate 321. A rotating wheel 3221 is coaxially fixedly connected to the output shaft of the drive motor 322. An eccentric shaft 3222 is fixedly connected to the rotating wheel 3221. The eccentric shaft 3222 is eccentrically set on one side of the rotating wheel 3221. One end of the eccentric shaft 3222 is rotatably connected to the connecting rod 323. A lower grinding plate 324 is slidably installed below the upper grinding plate 321. There is a gap between the upper grinding plate 321 and the lower grinding plate 324. Fixed shafts 3241 are fixedly connected to both sides of the lower grinding plate 324. The other end of the connecting rod 323 is rotatably connected to the fixed shafts 3241.

[0042] During the powdering process, the flour in the powder storage box 4 enters the gap between the upper grinding plate 321 and the lower grinding plate 324 through the powder inlet 3211. The gap allows fine flour to pass through, while lumpy flour cannot. The drive motor 322 drives the turntable to rotate. The rotating turntable drives the connecting rod 323 through the eccentric shaft 3222 to push the lower grinding plate 324 to slide back and forth under the upper grinding plate 321, crushing the lumpy flour. Driven by the lower grinding plate 324, the flour is discharged from the gap along with the fine flour.

[0043] Furthermore, a connecting sleeve 325 is fixedly connected to the top of the outer side of the powder-sprinkling head 32. The connecting sleeve 325 passes through the sliding groove 311 and is threaded onto the lead screw 315. Two sliders 326 are also fixedly connected to the top of the outer side of the powder-sprinkling head 32. The two sliders 326 are located on both sides of the connecting sleeve 325, and the sliders 326 are slidably mounted on the slide rail 313.

[0044] When the lead screw 315 rotates in the forward direction, the powder-spraying head 32 moves from the bearing seat 312 toward the servo motor 314 under the drive of the connecting sleeve 325. When the lead screw 315 rotates in the reverse direction, the powder-spraying head 32 moves from the servo motor 314 toward the bearing seat 312 under the drive of the connecting sleeve 325. Through the cooperation of the slider 326 and the slide rail 313, the powder-spraying head 32 can run stably on the fixed frame 31.

[0045] Furthermore, a screen 327 is fixedly installed at the bottom of the powder-spreading head 32. The screen 327 is located below the lower grinding plate 324. A connecting plate 33 is provided on the side of the powder-spreading head 32 facing the discharge end 12. Fixing rods 331 are fixedly connected to both sides of the connecting plate 33. The upper ends of the two fixing rods 331 are fixedly connected to both sides of the powder-spreading head 32. A cylinder 34 is fixedly installed on the connecting plate 33. The output shaft of the cylinder 34 is fixedly connected to the upper side of the powder-rubbing plate 35. Guide rods 351 are fixedly connected to the four corners of the powder-rubbing plate 35. The guide rods 351 slide through the connecting plate 33.

[0046] The sieve 327 has several mesh openings for fine flour to pass through. During flour spreading, when the fine flour is discharged from the gap between the upper grinding plate 321 and the lower grinding plate 324, it falls onto the sieve 327. After being sieved by the sieve 327, the fine flour is evenly spread onto the macaroni by the reciprocating flour spreading head 32. When the macaroni reaches the kneading plate 35, the cylinder 34 retracts its output shaft, driving the kneading plate 35 closer to the connecting plate 33, thereby increasing the distance between the kneading plate 35 and the electric conveyor belt 2, allowing the flour-spreading macaroni to pass through the kneading plate 35. As the macaroni sprinkled with flour enters below the rubbing plate 35, the cylinder 34 extends its output shaft, driving the rubbing plate 35 a suitable distance away from the connecting plate 33, so that the rubbing plate 35 contacts the upper side of the macaroni, but does not deform the macaroni. Then, as the flour-sprinkling head 32 moves the rubbing plate 35, the rubbing plate 35 rubs the macaroni below it, rolling it on the electric conveyor belt 2, fully coating it with flour. Then, the cylinder 34 retracts its output shaft, causing the rubbing plate 35 to move closer to the connecting plate 33 again, so that the flour-coated macaroni continues to move with the electric conveyor belt 2 towards the unloading end 12.

[0047] Furthermore, baffles 13 are fixedly installed on both sides of the mounting bracket 1, and a sliding rod 14 is fixedly connected between the two baffles 13. The sliding rod 14 is located above the connecting plate 33, and the connecting plate 33 is slidably connected to the sliding rod 14.

[0048] Among them, when conveying macaroni, the baffle 13 can effectively prevent macaroni from falling off the electric conveyor belt 2.

[0049] Furthermore, both sides of the powder storage box 4 are fixedly connected to a conveying pump 41. One of the conveying pumps 41 is connected to the powder inlet 3211 through a conveying pipe, and the other conveying pump 41 is connected to the bottom of the collection hopper 51 through another conveying pipe.

[0050] During the conveying of macaroni, the conveying pump 41 connected to the powder-sprinkling head 32 conveys the flour in the powder storage box 4 to the powder inlet 3211 through the conveying pipe on it. At the same time, the conveying pump 41 connected to the collecting hopper 51 conveys the flour collected in the collecting hopper 51 to the powder storage box 4 through the conveying pipe on it.

[0051] Furthermore, the powder collection component 5 includes a collection hopper 51, which is fixedly connected to the mounting frame 1, and a mesh screen 52 is fixedly connected to the opening of the collection hopper 51.

[0052] In this process, after the electric conveyor belt 2 transports the macaroni to the unloading end 12 for unloading, the flour remaining on the electric conveyor belt 2 will fall into the collection hopper 51 through the mesh 52. The collection hopper 51 will transport the collected flour back to the powder storage box 4. During the process of the macaroni being unloaded from the unloading end 12, any macaroni that accidentally falls will be intercepted by the mesh 52, preventing the macaroni from falling into the collection hopper 51.

[0053] Furthermore, the powder collection assembly 5 also includes a fixing plate 54 and a scraper plate 55. The fixing plate 54 is fixedly installed at the bottom of the unloading end 12 of the mounting frame 1 and is located above the collection hopper 51. A collection groove 541 is provided on the fixing plate 54. A sleeve 551 is fixedly connected to the bottom of the scraper plate 55. The sleeve 551 is slidably installed in the collection groove 541 and fits into the collection groove 541. A support spring 56 is fixedly connected between the bottom of the collection groove 541 and the top of the sleeve 551. The support spring 56 pushes the scraper plate 55 to move upward and abut against the electric conveyor belt 2.

[0054] When the electric conveyor belt 2 moves to the bottom of the unloading end 12, most of the flour remaining on the electric conveyor belt 2 will fall directly into the collection hopper 51, while some flour will stick to the electric conveyor belt 2. At this time, the scraper plate 55, which is supported by the spring 56 and pressed against the electric conveyor belt 2, will scrape off the flour stuck to the electric conveyor belt 2 and let it fall into the collection hopper 51 as well.

[0055] The present invention also provides a conveying method, which uses a conveying device for macaroni production, the specific steps of which are as follows:

[0056] First, the electric conveyor belt transports the macaroni from the loading end to the unloading end. The powder storage box 4 delivers the flour to the powder spreading head. The powder spreading head 32 moves back and forth above the electric conveyor belt 2, thus evenly spreading the flour on the macaroni. At the same time, the spreading head drives the rubbing plate 35 to move synchronously. The rubbing plate 35 rubs the flour-covered macaroni and rolls it on the electric conveyor belt 2, so that the surface of the macaroni is fully coated with flour, preventing the macaroni from sticking to the electric conveyor belt 2 during the conveying process. After the macaroni is unloaded from the unloading end 12, the remaining flour on the electric conveyor belt 2 is collected by the powder collecting component 5 and transported to the powder storage box 4 for reuse.

[0057] Working principle: During use, the electric conveyor belt 2, driven by the motor, transports the macaroni from the feeding end 11 to the unloading end 12. During the conveying process, the conveying pump 41, connected to the powder-spreading head 32, conveys the flour in the powder storage box 4 to the powder inlet 3211 through its conveying pipe. The flour enters the gap between the upper grinding plate 321 and the lower grinding plate 324 through the powder inlet 3211. The gap allows fine flour to pass through, while lumpy flour cannot pass through. At this time, the drive motor 322 drives the turntable to rotate. The rotating turntable drives the connecting rod 323 through the eccentric shaft 3222 to push the lower grinding plate 324 to slide back and forth under the upper grinding plate 321. This process breaks up any lumps in the flour and discharges them along with the finer flour particles through the gaps. Simultaneously, the servo motor 314 drives the lead screw 315 to rotate in both directions, causing the powder-sprinkling head 32 to reciprocate on the fixed frame 31. This, in turn, drives the dough-rubbing plate 35 to move synchronously. The moving powder-sprinkling head 32 evenly sprinkles the fine flour particles onto the macaroni on the electric conveyor belt 2. As the electric conveyor belt 2 continues to rotate, before the macaroni reaches the dough-rubbing plate 35, the cylinder 34 retracts its output shaft, driving the dough-rubbing plate 35 closer to the connecting plate 33. This increases the distance between the dough-rubbing plate 35 and the electric conveyor belt 2, allowing the flour-sprinkled macaroni to pass under the dough-rubbing plate 35. After the macaroni sprinkled with flour enters below the kneading plate 35, the cylinder 34 extends its output shaft, driving the kneading plate 35 a suitable distance away from the connecting plate 33, so that the kneading plate 35 contacts the upper side of the macaroni, but does not deform the macaroni. Then, as the flour-sprinkling head 32 moves the kneading plate 35, the kneading plate 35 kneads the macaroni below it, rolling it on the electric conveyor belt 2, fully coating it with flour. This allows the flour to absorb the moisture in the macaroni, reducing its stickiness and preventing it from sticking to the electric conveyor belt 2 during transportation. Then, the cylinder 34 retracts its output shaft, causing the kneading plate 35 to move back towards the connecting plate 33. As the flour-coated pasta continues to move along the electric conveyor belt 2 toward the unloading end 12, most of the flour remaining on the electric conveyor belt 2 will fall directly into the collection hopper 51. Some flour will stick to the electric conveyor belt 2. At this time, the scraper 55, which is supported by the spring 56 and pressed against the electric conveyor belt 2, will scrape off the flour stuck to the electric conveyor belt 2 and let it fall into the collection hopper 51. The collection hopper 51 will transport the collected flour back to the flour storage box 4, so that the excess flour can be reused, thereby reducing flour consumption and saving the production cost of pasta.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

6. A conveying method, characterized in that: The conveying device for macaroni production according to any one of claims 1-5 is used, and the specific steps are as follows: First, the electric conveyor belt transports the macaroni from the loading end to the unloading end. The powder storage box then delivers the flour to the powder spreading head. The powder spreading head reciprocates above the electric conveyor belt, evenly spreading the flour onto the macaroni. Simultaneously, the spreading head drives the powder rolling plate to move synchronously, causing the flour-coated macaroni to roll on the electric conveyor belt, ensuring the surface of the macaroni is fully coated with flour and preventing it from sticking to the electric conveyor belt during transport. After the macaroni is unloaded from the unloading end, the remaining flour on the electric conveyor belt is collected by the powder collection component and transported to the powder storage box for reuse.
