Description

Technical Field

[0001] This utility model relates to the field of flour sieving technology, and in particular to a flour pretreatment sieving machine for preventing caking. Background Technology

[0002] Flour is one of the raw materials for producing instant noodle cakes. In order to ensure the delicate texture of the cakes, the flour needs to be sifted.

[0003] A search revealed a flour sieving machine (publication number: CN112676144A) which includes a sieving box, a vibrating rod connected to the bottom of the sieving box, several stacked sieving screens inside the sieving box, a flour receiving tray below the bottommost sieving screen, a flour receiving tray outlet on the lower side of the sieving box, sieving screen outlets on the side of the sieving box and in the distribution section of the several sieving screens, and a feed pipe on the top of the sieving box.

[0004] In existing technologies, flour is screened using multiple sieves. The flour falls onto each sieve in sequence under gravity. During storage and transportation, the flour may clump together. Slightly clumped flour can be loosened by kneading. However, existing sieves do not have the ability to handle slightly clumped flour, resulting in the direct rejection of slightly clumped flour and waste of raw materials.

[0005] Therefore, we propose a flour pretreatment sieving machine to prevent caking. Utility Model Content

[0006] The present invention mainly solves the technical problem that the above-mentioned sieves cannot handle slightly clumped flour lumps, and provides a flour pretreatment sieving machine that prevents clumping.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an anti-caking flour pretreatment sieving machine, comprising:

[0008] The main body has a vibrating screen inside, and the top and bottom of the main body have windows for feeding and discharging materials. The side wall of the main body is fixedly provided with a material trough for discharging slag.

[0009] The feeding structure, located at the top of the main body and facing the window, is used to feed material to the vibrating screen. The feeding structure includes a feeding pipe, an auger, a mounting rod, a baffle, and ribs. The feeding pipe is fixedly installed to the main body, the mounting rod is fixedly connected to the feeding pipe, the auger is rotatably connected to the mounting rod, a motor is provided at the bottom of the mounting rod, the baffle is movably installed above the mounting rod, the gap between the baffle and the port of the feeding pipe can be adjusted, and several ribs are provided on the top of the baffle for guiding and extruding the flour.

[0010] An adjustment component, mounted on the mounting rod, is used to adjust the position of the baffle.

[0011] In a preferred embodiment of this utility model, the feed pipe is a round pipe that extends through the window at the top of the main body into the cavity of the main body, and the mounting rod is a U-shaped bracket, with both ends of the mounting rod fixedly connected to the lower end face of the feed pipe.

[0012] In a preferred embodiment of this utility model, a bushing is fixedly installed at the middle position of the feed pipe, the auger is rotatably connected to the bushing, the motor is fixedly installed at the bottom of the mounting rod, and the auger is fixedly connected to the output shaft of the motor.

[0013] In a preferred embodiment of this utility model, the baffle is a circular plate with a semi-circular arc-shaped rod at the end face of the rib, and several radially distributed ribs are fixedly installed on the top of the baffle.

[0014] In a preferred embodiment of this utility model, the adjusting component consists of two elastic telescopic rods disposed at the bottom of the mounting rod. The elastic telescopic rods are fixedly connected to the mounting rod, the output shaft of the elastic telescopic rods is slidably connected to the mounting rod, and the lower end face of the baffle is fixedly connected to the output shaft of the elastic telescopic rods.

[0015] In a preferred embodiment of this utility model, the adjustment assembly consists of a guide rod and an adjustment screw symmetrically arranged at the bottom of the mounting rod. The mounting rod is slidably connected to the mounting rod via the guide rod, and the adjustment screw is threadedly connected to the mounting rod and rotatably connected to the baffle.

[0016] In a preferred embodiment of this utility model, a sleeve adapted to an adjusting screw is fixedly installed at the bottom of the baffle. The end of the adjusting screw is rotatably connected to the sleeve. The mounting rod has a limit hole and a threaded hole. The adjusting screw is threadedly connected to the threaded hole. The guide rod is slidably connected to the limit hole and the end of the guide rod is fixedly connected to the baffle.

[0017] Beneficial effects

[0018] This utility model provides an anti-caking flour pretreatment sieving machine. It has the following beneficial effects:

[0019] 1. This anti-caking flour pretreatment screening machine involves feeding flour into the inlet of a feed pipe. A hopper is fixedly installed at the upper end of the feed pipe. By connecting the motor to the power supply, the motor drives the auger to rotate, which conveys the flour towards the window. A floating baffle can form a certain obstruction at the lower end of the feed pipe. The pressure exerted on the flour by the auger causes the baffle to shift, ensuring that the flour in the feed pipe has a certain pressure. Multiple spirally radiating ribs on the top surface of the baffle can guide and compress the flour. Slightly clumped flour can be compressed and dispersed. Combined with the screening and shaking of the vibrating screen, the flour can be dispersed, thus preventing flour from clumping. The clumped flour is discharged into the trough after passing through the vibrating screen. This machine handles slightly clumped flour during the screening process with high efficiency and good sorting effect.

[0020] 2. This anti-caking flour pretreatment sieving machine uses an elastic telescopic rod to push the baffle upwards. When the auger pushes the flour downwards, the flour can squeeze the baffle, causing the output shaft of the elastic telescopic rod to spring back. This increases the gap between the baffle and the feed pipe port, ensuring that the flour clumps are squeezed without causing excessive pressure inside the feed pipe due to the baffle being too close to the feed pipe port, which would lead to flour caking and blockage. At the same time, the gap between the baffle and the feed pipe port can be adaptively adjusted according to the feeding speed of the auger.

[0021] 3. This anti-caking flour pretreatment screening machine, by rotating the adjusting screw, drives the baffle to move upward, and the baffle drives the elastic telescopic rod to slide along the mounting rod, so that the distance between the baffle and the feed pipe can be adjusted and fixed. The gap between the baffle and the feed pipe can be controlled by manual adjustment, and the volume of the extruded agglomerated flour can be controlled according to the needs, which is more controllable and adjustable.

[0028] A flour pretreatment sieving machine for preventing caking, such as Figure 1 and Figure 2 As shown, it includes:

[0029] The main body 10 has a vibrating screen 11 inside. The top and bottom of the main body 10 have windows for feeding and discharging materials. The side wall of the main body 10 is fixedly equipped with a material trough for discharging slag. Specifically, flour is fed in through the upper window and sorted by the inclined vibrating screen 11. The slag slides down the top surface of the vibrating screen 11 and is discharged into the material trough. The flour falls to the bottom of the main body 10 and is discharged through the lower window, thus realizing the pre-treatment screening of flour. It is suitable for the processing of flour in the production of instant noodles.

[0030] like Figure 2 and Figure 3 As shown, the feeding structure, located at the top of the main body 10 and facing the window, is used to feed material to the vibrating screen 11. The feeding structure includes a feed pipe 20, an auger 21, a mounting rod 22, a baffle 23, and protruding ribs 24. The feed pipe 20 is fixedly installed to the main body 10, the mounting rod 22 is fixedly connected to the feed pipe 20, and the auger 21 is rotatably connected to the mounting rod 22. A motor is located at the bottom of the mounting rod 22. The baffle 23 is movably positioned above the mounting rod 22, and its gap with the feed pipe 20 port can be adjusted. Several guides and compression devices are provided on the top of the baffle 23. The feed pipe 20 is a round pipe that extends through the window at the top of the main body 10 into the cavity of the main body 10. The mounting rod 22 is a U-shaped bracket. The two ends of the mounting rod 22 are fixedly connected to the lower end face of the feed pipe 20. A bushing is fixedly installed in the middle position of the feed pipe 20. The auger 21 is rotatably connected to the bushing. The motor is fixedly installed at the bottom of the mounting rod 22. The auger 21 is fixedly connected to the output shaft of the motor. The baffle 23 is a round plate. The end face of the rib 24 is a semi-circular arc-shaped rod. Several radially distributed ribs 24 are fixedly installed on the top of the baffle 23.

[0031] In this scheme, flour is fed into the port of the feed pipe 20, and a hopper is fixedly installed at the upper port of the feed pipe 20. By connecting the motor to the power supply, the motor drives the auger 21 to rotate. The auger 21 conveys the flour toward the window, while the floating baffle 23 can form a certain obstruction at the lower port of the feed pipe 20. The squeezing force of the auger 21 on the flour causes the baffle 23 to move, ensuring that the flour in the feed pipe 20 has a certain pressure. The multiple spirally radiating convex ribs 24 on the top surface of the baffle 23 can guide and squeeze the flour. Slightly clumped flour can be squeezed and dispersed. With the screening and shaking of the vibrating screen 11, it can be dispersed, thus achieving the purpose of preventing flour from clumping. The clumped flour is sent into the trough for discharge through the vibrating screen 11. The process of handling slightly clumped flour during screening is efficient and has a good sorting effect.

[0032] Example 1, as Figure 4 As shown, the adjustment component is mounted on the mounting rod 22 to adjust the position of the baffle 23;

[0033] The adjustment component consists of two elastic telescopic rods 30 located at the bottom of the mounting rod 22. The elastic telescopic rods 30 are fixedly connected to the mounting rod 22, and the output shaft of the elastic telescopic rods 30 is slidably connected to the mounting rod 22. The lower end face of the baffle 23 is fixedly connected to the output shaft of the elastic telescopic rods 30. The elastic telescopic rods 30 provide an upward pushing force to the baffle 23. When the auger 21 pushes the flour downward, the flour can squeeze the baffle 23, causing the output shaft of the elastic telescopic rods 30 to spring back. This increases the gap between the baffle 23 and the port of the feed pipe 20. While ensuring the compression of the flour dough, it prevents the flour from caking and clogging due to excessive pressure inside the feed pipe 20 caused by the baffle 23 being too close to the port of the feed pipe 20. At the same time, it can adaptively adjust the size of the gap between the baffle 23 and the port of the feed pipe 20 according to the feeding speed of the auger 21.

[0034] Example 2, as Figure 5 As shown, the adjustment component is mounted on the mounting rod 22 to adjust the position of the baffle 23;

[0035] The adjustment assembly consists of a guide rod 40 and an adjusting screw 41 symmetrically arranged at the bottom of the mounting rod 22. The mounting rod 22 is slidably connected to the baffle 23 via the guide rod 40. The adjusting screw 41 is threadedly connected to the mounting rod 22 and rotatably connected to the baffle 23. A sleeve adapted to the adjusting screw 41 is fixedly installed at the bottom of the baffle 23. The end of the adjusting screw 41 is rotatably connected to the sleeve. The mounting rod 22 has a limit hole and a threaded hole. The adjusting screw 41 is threadedly connected to the threaded hole. The guide rod 40 is slidably connected to the limit hole and the end of the guide rod 40 is fixedly connected to the baffle 23.

[0036] In this solution, by rotating the adjusting screw 41, the adjusting screw 41 drives the baffle 23 to move upward, and the baffle 23 drives the elastic telescopic rod 30 to slide along the mounting rod 22. The distance between the baffle 23 and the feed pipe 20 can be adjusted and fixed. The gap between the baffle 23 and the feed pipe 20 can be controlled by manual adjustment. The volume of the extruded and agglomerated flour can be controlled according to the requirements, which makes it more controllable and adjustable.

[0037] The working principle of this utility model is as follows: Flour is fed into the port of the feed pipe 20. A hopper is fixedly installed at the upper port of the feed pipe 20. By connecting the motor to the power supply, the motor drives the auger 21 to rotate. The auger 21 conveys the flour towards the window. The floating baffle 23 can form a certain obstruction at the lower port of the feed pipe 20. The squeezing force of the auger 21 on the flour causes the baffle 23 to move, ensuring that the flour in the feed pipe 20 has a certain pressure. The multiple spirally radiating ribs 24 on the top surface of the baffle 23 can... The flour is guided and squeezed, and slightly clumped flour can be squeezed and dispersed. The elastic telescopic rod 30 provides an upward push to the baffle 23. When the auger 21 pushes the flour downward, the flour can squeeze the baffle 23, causing the output shaft of the elastic telescopic rod 30 to spring back. This increases the gap between the baffle 23 and the feed pipe 20 port. Alternatively, by rotating the adjusting screw 41, the adjusting screw 41 drives the baffle 23 to move upward. The baffle 23 drives the elastic telescopic rod 30 to slide along the mounting rod 22, thereby adjusting the position of the baffle 23.
