Description

Technical Field

[0001] This utility model relates to the field of konjac flour grading and screening technology, and in particular to a konjac flour grading and screening device. Background Technology

[0002] Konjac flour, a type of natural dietary fiber made from konjac as a raw material through a series of processing steps, has the effects of controlling weight, regulating blood lipids and blood sugar. In order to ensure the uniformity of the powder particles during the production of konjac flour, a special grading and screening device is often used to sieve the konjac flour according to different particle sizes.

[0003] To address this, patent specification CN214487093U discloses a grading and screening device for konjac flour processing. The device includes a first screening mechanism with a first feed inlet on its left side, a sieving cylinder movably connected inside the first screening mechanism, a conveying inlet on its right side, a conveying plate fixedly connected inside the second screening mechanism, a second crushing mechanism fixedly connected inside the second screening mechanism, and a second storage bin fixedly connected to the lower side of the second crushing mechanism. This grading and screening device for konjac flour processing uses a vibrating motor to perform preliminary screening of the konjac flour in the sieving cylinder. The sieving particles that need further processing can be crushed by the first crushing mechanism. The pre-screened konjac flour can then enter the second screening mechanism for further screening and crushing via the conveying plate. A pusher plate allows all remaining konjac flour to enter the second crushing mechanism and the third storage bin, thus achieving the effect of grading and screening. While the above-mentioned grading and screening device has a good screening effect when screening konjac flour, some problems still exist:

[0004] When the above-mentioned grading and screening device is performing screening operations, the holes in the screen plate are prone to blockage. If not dealt with in time, it will reduce the screening effect. Utility Model Content

[0005] The purpose of this invention is to provide a konjac flour grading and screening device to solve the problem of easy clogging of the sieve plate in existing konjac flour grading and screening devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a konjac flour grading and screening device, comprising a main frame and side frames, an electrical control panel fixedly connected to one end of the main frame, a sieve plate slidably connected inside the main frame, a top cover installed at the top of the main frame, a side frame fixedly connected to one side of the main frame, and anti-clogging structures fixedly connected to both ends inside the main frame. The anti-clogging structure includes a guide rail, a reciprocating screw, an internally threaded slider, a connecting plate, a telescopic rod, a support spring, and a brush. The guide rail is fixedly connected to both ends inside the main frame, a feed inlet is fixedly connected to the top of the top cover, and a screening structure is provided inside the side frames.

[0007] When in use, konjac flour is injected into the interior of the main frame through the feed inlet. Then, the device is started through the electronic control panel. At this time, the motor and pulley assembly drive several screen plates to reciprocate and shake laterally, so that several konjac flours are screened along the holes inside the screen plates. Since the device is placed at an angle, the screened konjac flour is gradually discharged from one side.

[0008] Preferably, the screening structure includes a guide rod, a roller, a transmission rod, a cam, and a return spring. One side of the guide rod is fixedly connected to one side of the screen plate, and the other side of the guide rod is fixedly connected to a roller. The two ends of the side frame are rotatably connected to the transmission rod. The two ends of the outer wall of the transmission rod are fixedly connected to the cam, and the outer side of the guide rod is fitted with a return spring.

[0009] Preferably, the guide rod has a sliding structure with the interior of one side of the side frame, and the guide rod is perpendicular to one side of the screen plate, so as to make the movement of the screen plate more stable.

[0010] Preferably, two sets of cams are fixedly connected to both ends of the outer wall of the transmission rod, and the two sets of cams are symmetrically distributed on the outer wall of the transmission rod, so that the screen plate can move smoothly back and forth laterally.

[0011] Preferably, a reciprocating lead screw is rotatably connected inside the guide rail, an internally threaded slider is sleeved on the outer side of the reciprocating lead screw, a connecting plate is fixedly connected to one end of the internally threaded slider, a telescopic rod is fixedly connected to the top of the connecting plate, a support spring is sleeved on the outer side of the telescopic rod, and a brush is fixedly connected to the top of the telescopic rod.

[0012] Preferably, the guide rail and the reciprocating lead screw are in a rotating structure, and the reciprocating lead screw and the internal threaded slider are in a threaded connection structure, so that the brush can move laterally back and forth.

[0013] Preferably, the guide rail and the internal threaded slider have a sliding structure, and the telescopic rods are evenly distributed at the top of the connecting plate, so that the top of the brush is in close contact with the bottom of the screen plate.

[0014] Compared with the existing technology, the beneficial effects of this utility model are: the reciprocating screw driven by the motor drives the brush to clean the screen plate through the internal thread slider, thereby avoiding the blockage of the holes inside the screen plate. At the same time, under the drive of the motor, several transmission rods drive the cam to rotate, thereby causing several screen plates to shake at the same time, thereby screening the konjac flour.

[0015] 1. Under the action of the motor and the transmission wheel, the reciprocating screw gradually rotates, thereby causing the internal threaded slider connected to the reciprocating screw to move reciprocally laterally along the inside of the guide rail. During the movement, the connecting plate is driven, thereby enabling the brush to clean the bottom of the screen plate.

[0016] Furthermore, several telescopic rods and support springs are fixed to the top of the connecting plate to ensure that the brush is always in close contact with the bottom of the screen plate, thereby maintaining the cleaning effect of the device.

[0017] 2. Under the action of the motor and the transmission wheel, several transmission rods drive the cam to rotate, and under the elastic force of the return spring, the roller is pressed against the outer side of the cam, so that the screen plate can move back and forth laterally as the cam rotates.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a konjac flour grading and screening device, including a main frame 1 and a side frame 6. An electrical control panel 2 is fixedly connected to one end of the main frame 1. A sieve plate 3 is slidably connected inside the main frame 1. A top cover 4 is installed at the top of the main frame 1. A side frame 6 is fixedly connected to one side of the main frame 1. A feed inlet 5 is fixedly connected to the top of the top cover 4. A screening structure 7 is provided inside the side frame 6. The screening structure 7 includes a guide rod 701, a roller 702, a transmission rod 703, a cam 704, and a return spring 705. A guide rod 701 is fixedly connected to one side of the side frame 6. A guide rod 701 is fixedly connected to one side of the sieve plate 3, and a roller 702 is fixedly connected to the other side of the guide rod 701. A transmission rod 703 is rotatably connected to both ends inside the side frame 6. A cam 704 is fixedly connected to both ends of the outer wall of the transmission rod 703. A return spring 705 is sleeved on the outer side of the guide rod 701. The guide rod 701 and the interior of one side of the side frame 6 have a sliding structure. The guide rod 701 is perpendicular to one side of the sieve plate 3. Two sets of cams 704 are fixedly connected to both ends of the outer wall of the transmission rod 703, and the two sets of cams 704 are symmetrically distributed on the outer wall of the transmission rod 703.

[0026] See attached document Figure 2 , Figure 3 and Figure 4 When the device is in use, in order to make the shaking of the screen plates 3 more stable, the transmission rod 703 is rotated inside the side frame 6. Under the action of the motor and the transmission wheel, the transmission rod 703 drives the cam 704 to rotate. Under the elastic force of the return spring 705, the roller 702 is pressed against the outside of the cam 704. Thus, the screen plates 3 can move back and forth laterally as the cam 704 rotates.

[0027] Both ends of the main frame 1 are fixedly connected to an anti-blocking structure 8. The anti-blocking structure 8 includes a guide rail 801, a reciprocating lead screw 802, an internal threaded slider 803, a connecting plate 804, a telescopic rod 805, a support spring 806, and a brush 807. The guide rail 801 is fixedly connected to both ends inside the main frame 1. The reciprocating lead screw 802 is rotatably connected inside the guide rail 801. An internal threaded slider 803 is sleeved on the outer side of the reciprocating lead screw 802. One end of the internal threaded slider 803 is fixed. A connecting plate 804 is fixedly connected, and a telescopic rod 805 is fixedly connected to the top of the connecting plate 804. A support spring 806 is sleeved on the outside of the telescopic rod 805, and a brush 807 is fixedly connected to the top of the telescopic rod 805. The guide rail 801 and the reciprocating screw 802 are in a rotating structure. The reciprocating screw 802 and the internal thread slider 803 are in a threaded connection structure. The guide rail 801 and the internal thread slider 803 are in a sliding structure. The telescopic rods 805 are evenly distributed at the top of the connecting plate 804.

[0028] See attached document Figure 2 and Figure 5 When the device is in use, the sieve plate 3 vibrates back and forth, and sieves the konjac flour during the vibration process. However, after long-term use, large particles of konjac flour can easily clog the holes inside the sieve plate 3, thus gradually reducing the sieving effect of the sieve plate 3. To address this, guide rails 801 are fixed at both ends inside the main frame 1. Under the action of the motor and transmission wheel, the reciprocating screw 802 gradually rotates, causing the internally threaded slider 803, which is threaded to the reciprocating screw 802, to reciprocate laterally along the guide rail 801. During the movement, the connecting plate 804 is driven, so that the brush 807 cleans the bottom of the sieve plate 3 and removes the powder particles clogging the inside of the sieve plate 3. Since the brush 807 is prone to wear after long-term use, in order to keep the brush 807 in close contact with the bottom of the sieve plate 3, several telescopic rods 805 and support springs 806 are fixed to the top of the connecting plate 804. This ensures that the brush 807 is always in close contact with the bottom of the sieve plate 3, thus maintaining the cleaning effect of the device.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
