Description

Technical Field

[0001] The utility model relates to a drum-type rice noodle sorting mechanism, belonging to automatic rice noodle production equipment. Background Art

[0002] As a traditional food in China, rice noodles are consumed in many regions. The production and deep processing of rice noodles are divided into dried rice noodles after drying and wet rice noodles without drying according to their moisture content. Wet rice noodles have a short shelf life and are not conducive to storage. They are instant consumables with a small product coverage. Dried rice noodles have a long shelf life and are convenient for transportation, so they have a large consumer market.

[0003] The production and deep processing processes of dried rice noodles are similar. Their main processes include two parts, one is the rice noodle production process, and the other is the rice noodle deep processing process. In the deep processing process of rice noodles, there are relatively mature integrated devices for drying and cutting rice noodles, which can achieve efficient drying and cutting after rice noodle production. For example, the fully enclosed intelligent rice noodle drying and cutting system developed by China National Packaging and Food Machinery Corporation has been widely used in the industry.

[0004] In the sorting, weighing, and packaging stages of the deep processing process, after the rice noodles are dried and cut, due to the change in the shape and appearance of the rice noodles, deep processing processes such as sorting, weighing, and packaging of the rice noodles are required. After drying, the texture of the rice noodles becomes hard and brittle, and the friction between them and the conveyor belt of the processing production line becomes smaller. During the cutting and subsequent conveying of the rice noodles, the placement posture of the rice noodles on the conveyor belt will be disordered. In particular, there are many dried rice noodles with a large degree of bending after drying, which are easily entangled with each other, causing great difficulties for the subsequent automatic sorting and packaging in the deep processing process of rice noodles. At present, the main method in the rice noodle processing production line is still manual sorting and straightening after the rice noodles are dried and cut, which has a large labor intensity and is prone to missed selection.

DETAILED DESCRIPTION

[0030] Example

[0031] See also Figures 1-3 The drum-type rice noodle sorting mechanism shown in the figure is a specific implementation scheme of the utility model, which specifically includes a screening drum 1, a feeding drum 2, a supporting driven wheel 3, a first side plate 41, a second side plate 42, a bottom plate 5, and a driving wheel 6, wherein the screening drum 1 is supported and arranged on a frame formed by splicing the first side plate 41, the second side plate 42 and the bottom plate 5, a plurality of screening grooves 100 are arranged on the circumferential surface of the screening drum 1, and all the screening grooves 100 are distributed along the axial direction of the drum, the side end surface of the screening drum 1 is connected to the rice noodle feeding transmission channel 7, and a rice noodle discharging transmission channel 8 is arranged below the outer periphery of the drum, the screening drum 1 is connected to the driving component in a transmission manner, and the driving component drives the screening drum 1 to rotate, so that the rice noodles in the screening drum 1 roll over and fall on the discharging transmission channel 7 below in a uniform direction through the screening grooves 100.

[0032] The rice noodles referred to in the present embodiment refer to a single strip of rice noodles after drying and cutting, the rice noodles after drying and cutting are fed into the screening drum 1 from the feed transmission channel, the rice noodles are turned over in the screening drum 1, and the rice noodles entangled together can be scattered, the width of the sieve slot 100 on the screening drum 1 is slightly larger than the diameter of the rice noodles, and the qualified straight strip rice noodles will be uniformly embedded in the sieve slot 100 of the screening drum along the drum axial direction, and the embedded rice noodles fall into the rice noodles discharging transmission channel 8 below when the sieve slot 100 rotates to the bottom with the screening drum, and the rice noodles that do not enter the sieve slot 100 continue to roll with the screening drum until entering the sieve slot, and the rice noodles that are left that cannot enter the sieve slot are defective rice noodles with excessive curvature, so that the automatic sorting of rice noodles is realized. Due to the limit of the sieve slot 100, all the rice noodles that fall into the rice noodles discharging transmission channel are uniformly distributed along the axial direction of the screening drum, and the rice noodles are also straightened while sorting the rice noodles, which is more conducive to the weighing and packaging of the subsequent rice noodles.

[0033] In this embodiment, further, one end face of the screening drum 1 is closed, and this closed end face is used for driving connection with the driving component. The other end face is open, and the opening of the drum is docked with the rice noodle feeding and conveying channel for feeding rice noodles into the screening drum.

[0034] Specifically, as Figure 4 shown, the screening drum 1 in this embodiment includes filter bars 11 and drum end caps 12. A plurality of filter bars 11 are arranged in parallel and are arranged in the circumferential direction of the drum to enclose the cylindrical circumferential surface of the screening drum. The gaps between the filter bars are the sieve slots 100, and all the sieve slots 100 are distributed along the axial direction of the screening drum and are parallel to each other. The ends of all the filter bars 11 on the same side are fixedly connected to the drum end cap 12 to form the overall structure of the screening drum, and the drum end cap 12 serves as the closed end face of the screening drum 1 for driving connection with the driving component. The ends of all the filter bars 11 on the other side are fixedly connected to the feeding cylinder 2, and the screening drum 1 is connected and communicated with the connected rice noodle feeding and conveying channel through the feeding cylinder 2.

[0035] Furthermore, as Figure 5 shown, the filter bars 11 in this embodiment adopt a Z-shaped cross-section. An outlet fold 111 is provided on the outside of the screening drum for the filter bars 11, and an inlet fold 112 is also provided on the inside of the screening drum for the filter bars 11. The inlet fold 112 and the outlet fold 111 protrude from the filter bars in two opposite directions. Connecting holes 113 are provided at both ends of the filter bars 11, and a plurality of connecting holes distributed along the circumference are provided on the feeding cylinder 2 and the drum end cap 12. The filter bars 11 can be fixedly connected to the connecting holes on the feeding cylinder 2 and the drum end cap 12 through bolts or rivets.

[0036] As Figure 6 shown, the outlet folds 111 of all the filter bars are arranged in the opposite direction of the sorting rotation direction of the screening drum. When the rice noodles entering the sieve slots between the filter bars have not rotated to the lowest position of the screening drum with the screening drum, they are blocked by the outlet folds 111, preventing the rice noodle strips entering the sieve slots from falling out of the screening drum prematurely. After the rice noodle strips in the sieve slots rotate past the lowest position with the screening drum, the outlet folds 111 lose the blocking effect of the rice noodle strips in the sieve slots, and the rice noodle strips can freely fall from the sieve slots into the lower rice noodle discharging and conveying channel.

[0037] The inlet folds 112 of all the filter bars are arranged in the sorting direction of the screening drum. When the rice noodles entering the sieve slots between the filter bars are rotated to the top of the drum with the screening drum, they are blocked by the inlet folds 112, preventing the rice noodle strips entering the sieve slots from falling off the sieve slots into the screening drum again, and improving the stability of the rice noodles entering the sieve slots.

[0038] Both ends of the screening drum 1 are respectively supported on the frame through the feeding cylinder 2 and the drum end cap 12. The feeding cylinder 2 is supported by rollers, and the drum end cap 12 is supported by a driving shaft + bearing.

[0039] Specifically, the frame of this embodiment includes a first side plate 41, a second side plate 42 and a bottom plate 5, which are respectively used for supporting and assembling the corresponding feed drum 2 and the drum end cover 12. Among them, two groups of supporting driven wheels 3 of equal height are arranged on the top of the first side plate 41, and the circumferential outer diameter of the feed drum 2 is directly mounted on the two groups of driven supporting wheels 3 to form a stable triangular wheel group support structure, and the use of roller support does not occupy the feeding space of the inner ring of the feed drum 2. The drum end cover 12 at the other end of the screening drum 1 is a closed end, which is directly and coaxially fixedly connected to the driving shaft of the driving component. The driving shaft is assembled on the second side plate 42 through a bearing to realize the supporting arrangement of the other end of the screening drum. The first side plate 41 and the second side plate 42 are fixedly connected to the bottom plate 5 to form the frame as a whole.

[0040] In this embodiment, the driving component for driving the screening drum includes a driving wheel 6, which is coaxially fixed to the drum end cover 12 of the screening drum 1 through a driving shaft, and the driving shaft is assembled through the second side plate 42 through a bearing, and the driving wheel 6 is connected to the driving motor. In actual applications, the transmission structure adopted by the driving component includes but is not limited to belt transmission, gear transmission, and chain transmission.

[0041] In this embodiment, a hand crank 61 is also provided on the outer end surface of the driving wheel 6 for manually driving the screening drum to rotate. The hand crank 61 is convenient for debugging and measuring the rotation speed of the screening drum.

[0042] After starting the power supply of the driving motor, the driving component drives the screening drum 1 to rotate, and rice noodles are added from the feeding cylinder 2 to the screening drum 1 through the rice noodle feeding transmission channel 7. The rice noodles are turned over in the drum as the screening drum 1 rotates, and the rice noodles with normal size and straightness enter the screening slots 100 between the filter strips 11 and fall onto the rice noodle discharging transmission channel 8 below as the drum rotates, and are transmitted to the next process. The rice noodles screened by the screening drum 1 are individually sorted through each screening slot and fall into the rice noodle discharging transmission channel. The rice noodles are separated individually and not stacked; the bent rice noodles remain in the screening drum to achieve sorting.
