[0031] Example one

[0032] Referring to Figure 1 , the drawing is one specific implementation scheme of the multi-hole vibrating type rice powder automatic sorting device of the utility model, and specifically includes screening frame 101, vertical plate 102, hopper 103, first vertical pipe 104, screen plate 105, second vertical pipe 106, unqualified product frame 107, vibration mechanism 108, slideway 109 and translation air cylinder 110, wherein the screening frame 101 is the device main body installation structure, the hopper 103, the first vertical pipe 104, the screen plate 105, the slideway 109, the translation air cylinder 110 are all installed on the screening frame 101 through the vertical plate 102, and the second vertical pipe 106 and the unqualified product frame 107 are directly installed on the screening frame 101.

[0033] The main body for sorting straight rice noodles and curved rice noodles in this embodiment is a first vertical pipe 104, a sieve plate 105 and a second vertical pipe 106. The first vertical pipe 104 and the second vertical pipe 106 are movably connected in the vertical direction. The first vertical pipe 104 is located above the second vertical pipe 106 and is arranged to slide in the horizontal direction. The first vertical pipe 104 is connected to the second vertical pipe 106 at a first positioning point on the sliding route. The sieve plate 105 is fixedly arranged at the joint of the first vertical pipe 104 and the second vertical pipe 106. As shown in Figure 2 , the sieve plate 105 is provided with a plurality of sieve holes for the straight rice noodles to pass through. The first vertical pipe 104 is connected to the lower unqualified product frame 107 at a second positioning point on the sliding route. The first vertical pipe 104 and the second vertical pipe 106 are connected through the sieve plate at the first positioning point. The straight rice noodles are sieved out. The first vertical pipe 104 slides horizontally to the second positioning point. The curved noodles are transferred to the unqualified product frame. The automatic sorting of the straight rice noodles and the curved rice noodles is realized.

[0034] The first vertical pipe 104 is used to put the rice noodles to be sieved. The rice noodles to be sieved are independent noodles. The noodle strands of the rice noodles to be sieved enter the first vertical pipe 104 in a vertical bundle. In the sieving state of the joint of the first vertical pipe 104 and the second vertical pipe 106, the noodle strands in the first vertical pipe 104 fall into the second vertical pipe 106 under the action of gravity. The straight rice noodles pass through the sieve holes of the sieve plate 105 and fall directly into the second vertical pipe 106. The straight rice noodles are sieved out of the rice noodles to be sieved. The first vertical pipe 104 slides to the second positioning point. The curved rice noodles in the first vertical pipe 106 fall into the unqualified product frame 107.

[0035] In actual application, there are two cases of curved rice noodle strands. One is that the whole rice noodle strand is curved or the curved section is downward. Such rice noodle strand cannot enter the sieve holes of the sieve plate due to the bending of the end part to the side. Therefore, the rice noodle strand is completely intercepted in the first vertical pipe 104 by the sieve plate. After the first vertical pipe 104 slides horizontally to the second positioning point, the curved rice noodle strand directly falls into the unqualified product frame 107. The other is that the rice noodle strand is partly curved and partly straight, and the straight section is downward. The downward straight section is blocked by the remaining curved section after entering the sieve holes of the sieve plate 105. At this time, part of the rice noodle strand passes through the sieve plate, and the other part remains in the first vertical pipe 104. The first vertical pipe 104 cuts off the rice noodle strand from the blocked part in the horizontal direction during the horizontal sliding process. The curved part of the rice noodle strand falls into the unqualified product frame 107 with the first vertical pipe 104. The straight rice noodles that have passed through the sieve plate 105 fall into the second vertical pipe 106 through the sieve holes. The sieving of the straight rice noodles and the curved rice noodles is still realized. The partly cut straight rice noodles directly enter the subsequent packaging or are selected through the subsequent visual sorting station according to production requirements.

[0036] The first vertical pipe 104 in the embodiment is arranged on the vertical plate 102 through the transversely arranged slide rail 109, and is connected with the translation cylinder 110 mounted on the vertical plate 102, and the first vertical pipe 104 is driven to slide transversely along the slide rail 109 through the translation cylinder 110.

[0037] In the embodiment, three groups of transversely parallel slide rails are adopted according to the length of the first vertical pipe 104, the slide rails 109 are fixed on the vertical plate 102, the three groups of slide rails share the same slide plate, the first vertical pipe 104 is vertically fixed on the slide plate shared by the three groups of slide rails through pipe clamps, the translation cylinder 110 is arranged parallel to the slide rails, and the first vertical pipe 104 is driven to slide transversely. The vertical plate 102 is provided with a positioning sensor at the first positioning point and the second positioning point of the sliding route of the first vertical pipe 104, the positioning sensor is feedback connected with the translation cylinder 110, and the translation cylinder 110 is feedback controlled to accurately slide the first vertical pipe 104 to the first positioning point and the second positioning point, and accurately butt joint with the second vertical pipe and the unqualified product frame respectively.

[0038] The sieve plate 105 is fixedly arranged at the first positioning point of the sliding route of the first vertical pipe 104, and in the embodiment, the sieve plate 105 is fixed on the vertical plate 102 through a screw connecting piece, and is fixedly arranged relative to the first vertical pipe 104, and after the first vertical pipe 104 slides to the first positioning point, the lower end discharge port of the first vertical pipe 104 is blocked by the sieve plate 105; and the second vertical pipe 106 is vertically fixed on the screening machine rack 101 mounted on the vertical plate.

[0039] The sieve plate 105 is fixedly arranged on the vertical plate 102 and is in alignment with the lower end discharge port of the first vertical pipe 104 sliding to the first positioning point, the first vertical pipe 104 and the sieve plate 105 are connected with the vibration mechanism 108 through the vertical plate 102, and the vibration of the first vertical pipe is controlled to improve the efficiency of the straight strip type rice flour passing through the sieve holes of the sieve plate.

[0040] The vibrating mechanism 108 makes the vertical plate 102 and the noodles in the first vertical tube 104 to be in a vibrating state, and improves the probability of the straight noodles passing through the sieve holes of the sieve plate. Since the first vertical tube 104 is installed on the vertical plate 102, in order not to affect the precision of the slide rail due to the vibration of the first vertical tube 104, the first vertical tube 104 is connected with the vibrating mechanism through the vertical plate 102 in the embodiment, the vertical plate 102 is movably installed on the screening frame 101 through a reciprocating mechanism, and in the embodiment, the vertical plate 102 is slidably installed on the screening frame 101 through two groups of guide rails perpendicular to the plane of the vertical plate. The vibrating mechanism 108 adopts a cam connecting rod mechanism, the vibrating motor drives the cam end of the cam connecting rod mechanism, the connecting rod end of the cam connecting rod mechanism is connected with the vertical plate 102, the vibrating motor drives the cam connecting rod mechanism to drive the vertical plate 102 to slide back and forth relative to the screening frame 101 to realize vibration, and then the vibration of the first vertical tube 104 and the sieve plate 105 installed thereon is realized. The vibration range of the vibrating mechanism 108 driving the vertical plate does not exceed the edge of the sieve plate 105, so that the noodles are prevented from leaking out in the vibration process. The vibrating mechanism of the vibrating motor driving the reciprocating mechanism is a mature technology, and the specific structure of the vibrating mechanism arranged on the back of the vertical plate is not described herein.

[0041] In order to facilitate the noodles to be sent into the first vertical tube 104 in bundles, a hopper 103 is arranged at the upper end of the first vertical tube 104, so that the noodles to be screened can quickly and accurately enter the first vertical tube 104.

[0042] Embodiment two

[0043] Referring to Figure 3 , the rice automatic sorting device in the illustration is another specific implementation scheme of the utility model, which is based on the embodiment one, and the lower end of the second vertical tube 106 is connected with the visual sorting station 400 through the rice noodle special belt conveyor, the visual sorting station 400 is provided with an industrial camera for visually sorting the appearance and size of the screened straight rice noodles, the screened straight rice noodles are laid on the belt conveyor and conveyed to the visual sorting station to be photographed by the industrial camera, the length and appearance quality of the noodles in the photographed image are judged through the set image processing algorithm, and the straight rice noodles with unqualified size and appearance are selected. The embodiment provides a rice automatic sorting device combining the embodiment one with the visual sorting equipment, the image processing algorithm of the industrial camera for sorting the length and appearance of the noodles is a mature image processing technology, which does not belong to the object protected by the utility model, and the specific scheme of the visual sorting is not described herein.

[0044] Referring to Figure 3 and Figure 4The rice powder automatic sorting device of the embodiment is further connected with the feeding hopper 200 through the setting of the lifting assembly 300 at the upper end feeding port of the first vertical pipe 104, and automatic feeding of the rice powder sorting is realized. Specifically, the lifting assembly 300 includes a lifting motor 301, a lifting module 302, a lifting hopper 303, a limit sensor 304, a lifting rack 305, and a slide 306. The lifting hopper 303 is a carrier container for lifting and transferring the rice powder to be screened. The lifting hopper 303 is liftingly arranged between the discharge port of the feeding hopper 200 and the upper end feeding port of the first vertical pipe. The lifting hopper 303 used in the embodiment is a strip-shaped hopper with a wide upper end and a narrow lower end. The length of the hopper corresponds to the length of the rice powder strip. The rice powder strip can be stacked in the hopper in one direction. The bottom of the hopper is arranged to be inclined, and an openable discharge door is arranged at the lower end of the hopper. The discharge door is normally closed during the lifting and lowering process of the lifting hopper. The discharge door is opened after the lifting hopper is lifted to be connected with the upper end feeding port of the first vertical pipe. The inclined arrangement of the hopper bottom facilitates the rice powder to slide out of the hopper by gravity. In the embodiment, the lifting hopper 303 is connected with the discharge port of the feeding hopper 200 through the side of the hopper, that is, the rice powder strip in the feeding hopper 200 falls into the hopper from the side and is stacked in the lifting hopper 303 in the length direction of the rice powder strip. The rice powder strip is discharged from the lifting hopper 303 through the discharge door at the end of the hopper and is connected with the upper end feeding port of the first vertical pipe. The lifting rack 305 is provided with an inclined slide 306. The lifting hopper 303 is connected with the upper end feeding port of the first vertical pipe through the slide 306. The high position of the slide 306 is aligned with the discharge door at the end of the lifting hopper 303 after lifting, and the low position is connected with the funnel 103 at the upper end feeding port of the first vertical pipe. The rice powder strip sliding out of the lifting hopper 303 accurately slides into the first vertical pipe through the slide 306. The slide 306 can constrain the rice powder to slide into the first vertical pipe in the length direction of the rice powder strip.

[0045] The lifting hopper 303 is connected with the lifting module 302 and is liftingly arranged on the lifting rack 305. The lifting motor 301 is drivingly connected with the lifting module 302. The lifting module 302 drives the lifting hopper 303 to move up and down. The lifting module 302 can adopt a lifting chain mechanism, a lifting belt mechanism, a lifting rack mechanism, or a lifting screw mechanism arranged vertically along the lifting rack. The rotation of the lifting motor 301 is converted into the linear motion of the lifting hopper 303 to realize the lifting motion of the lifting hopper 303. The above lifting mechanisms are mature linear transmission modules, and the specific structure is not described herein.

[0046] In order to further control the accurate lifting positioning of the lifting hopper 303 at the positions of descending and feeding and rising and discharging, limit sensors 304 are arranged at the positions where the lifting hopper 303 is connected with the discharge port of the feeding hopper and the upper end feeding port of the first vertical pipe in the embodiment, Figure 4The limiting sensor in the position where the lifting hopper 303 is in butt joint with the upper end feeding port of the first vertical pipe is only shown, and the limiting sensor in the position where the upper feeding hopper is in butt joint is arranged on the upper feeding hopper. The limiting sensor 304 can adopt a photoelectric sensing switch or a position proximity switch. The limiting sensor 304 is in communication feedback connection with the lifting motor 301. When the lifting hopper 303 is lifted to trigger the limiting sensor, the feedback controls the lifting motor 301 to stop moving, and the lifting hopper 303 is stopped at the limiting position to realize accurate feeding and discharging. The limiting sensor in the position where the lifting hopper is in butt joint with the high position of the slide is also in feedback control of the discharge door on the lifting hopper. That is, when the lifting hopper 303 is lifted to trigger the limiting sensor in the position where the lifting hopper is in butt joint with the slide, the lifting hopper stops rising, and the discharge door is opened to make the rice noodle in the lifting hopper slide into the first vertical pipe through the slide, so as to realize automatic discharging. The discharge door is closed after the signal of the limiting sensor in this position is disconnected.
