Description

Technical Field

[0001] The present invention relates to the technical field of quantitative feeding, and particularly relates to an ultrasonic swing sieve quantitative feeding device for corn starch production. Background Art

[0002] In the process of corn starch production, an ultrasonic swing sieve is a key screening device for classifying and removing impurities from starch granules. Its working principle is to combine mechanical swinging and ultrasonic vibration to make the starch granules evenly distributed on the sieve mesh and efficiently pass through the sieve. However, in the actual production process, the problems of quantitative feeding and uniform distribution of materials directly affect the screening efficiency and product quality.

[0003] Currently, the ultrasonic swing sieve usually adopts a feeding method with a central fixed feeding pipe. The material vertically falls into the central area of the sieve mesh through the feeding pipe, and then diffuses outward under the action of swinging and ultrasonic vibration. This feeding method has the following technical problems:

[0004] Serious central accumulation phenomenon:

[0005] Due to the fixed feeding pipe, the material continuously concentrates at the center of the sieve mesh, resulting in too thick a material layer in this area, affecting the transmission of vibration energy and reducing the screening efficiency.

[0006] The accumulated material may block the sieve mesh, increase the equipment load, and even affect the normal operation of the ultrasonic vibrator.

[0007] Therefore, an ultrasonic swing sieve quantitative feeding device for corn starch production is needed to overcome the above problems. Summary of the Invention

[0008] To solve the above problems, the embodiment of the present invention provides an ultrasonic swing sieve quantitative feeding device for corn starch production, achieving the purpose of solving the problems proposed in the background art.

[0009] The embodiment of the present invention specifically adopts the following technical solutions to achieve the above purpose: An ultrasonic swing sieve quantitative feeding device for corn starch production, comprising: a cylinder body arranged at the feeding port of the swing sieve, a material cylinder arranged inside the cylinder body to provide a space for storing materials, a cloth-feeding assembly for driving the material cylinder to move so that the discharge port of the material cylinder changes its position above the sieve mesh of the swing sieve, and a blanking assembly arranged on the cylinder body to discharge the materials inside the material cylinder from the discharge port along with the movement of the material cylinder;

[0010] The material is added into the material cylinder, and the cloth-feeding assembly is used to drive the material cylinder to rotate. After the material cylinder rotates, the materials inside the material cylinder are discharged through the blanking assembly, realizing that the materials are evenly distributed on the sieve mesh of the swing sieve when the material cylinder discharges.

[0011] As a technical solution for a cloth assembly, the cloth assembly includes: a gear ring fixedly connected to the outside of a barrel, a gear shaft meshingly arranged on one side of the gear ring, and a motor installed on the outside of the barrel to drive the gear shaft to rotate; after the motor drives the gear shaft to rotate, it drives the gear ring to rotate, thereby driving the barrel to rotate.

[0012] As a technical solution of the material discharge assembly, the material discharge assembly includes: a shaft body, which is rotatably arranged inside the barrel, a rotor, which is fixedly connected to the outside of the shaft body and drives the material inside the barrel to be discharged after rotation, a ring, which is fixedly connected to the inside of the barrel, a driving wheel, which is attached to the side of the ring and rotates with the rotation of the barrel, a worm, which is fixedly connected to the driving wheel, and a worm wheel, which is meshed with one side of the worm and is transmission-connected to the shaft body through a connecting rod;

[0013] After the barrel rotates, it drives the driving wheel to revolve, and through the friction between the ring and the driving wheel, the driving wheel is driven to revolve, thereby driving the shaft to rotate through the worm and worm gear, so that the rotor rotates and then the material inside the barrel is discharged.

[0014] As further explanation of the blanking assembly:

[0015] A driving assembly for driving the barrel to move is arranged on the outside of the barrel; the unloading assembly comprises: an outer shell, which is covered on the outside of the worm and the worm wheel, a connecting groove, which is opened inside the shaft body and plugged with the connecting rod, a spring 1, which is sleeved on the outside of the connecting rod and is located between the outer shell and the barrel, and a limit rod, which is fixedly connected to the barrel, passes through the inside of the outer shell, and is sleeved on the outside with a spring 2 located between the outer shell and the barrel; wherein the driving wheel is conical and one side of the ring is arc-shaped.

[0016] The driving assembly comprises: a connecting frame rotatably connected to the outside of the barrel, and an electric push rod arranged on the barrel body and used to push the connecting frame to move.

[0017] The outer diameter of the barrel is the same as the inner diameter of the barrel body, and a baffle with the same inner diameter as the barrel body is fixedly connected to the discharge port of the barrel.

[0018] The top of the barrel is rotatably connected with a feed pipe, and the inside of the feed pipe is fixedly connected with a stirring frame extending into the inside of the barrel.

[0019] The beneficial effects of the embodiments of the present invention are:

[0020] In actual use, after adding materials into the interior of the barrel, start the cloth feeding component, and the cloth feeding component drives the barrel to rotate inside the cylinder body. Since the discharge port of the barrel is offset at the bottom of the barrel, the position of the discharge port will continuously change when the barrel rotates. At the same time, the rotation of the barrel will drive the feeding component to move, so as to realize the operation mode of discharging while the barrel rotates. This linkage mechanism enables the materials to be evenly distributed on the sieve mesh of the shaking screen through the dynamically changing discharge port, preventing the materials from continuously concentrating at a certain position of the sieve mesh and causing the phenomenon of central accumulation;

[0021] The wide-range precise control of the feeding speed is realized through two independent adjustment mechanisms (speed adjustment + height mechanical adjustment): Dynamic response adjustment: directly change the rotation speed of the barrel by adjusting the speed of the motor, which is suitable for rapid response requirements; Mechanical compensation adjustment: change the transmission ratio at the driving wheel by adjusting the height, which is suitable for fine speed stability requirements. The dual adjustment method significantly expands the adaptability of the equipment to process requirements such as different material fluidity and screening accuracy.

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0033] See also Figures 1 to 3 The embodiment of the present invention discloses an ultrasonic swing screen quantitative feeding device for corn starch production, comprising: a barrel 1 connected to the swing screen feed port; a barrel 2 for storing materials is movably arranged inside the barrel 1, a material distribution component 3 for driving the barrel to rotate is arranged outside the barrel 2 and the barrel 1, and a material discharge component 4 for discharging the material inside the barrel 2 is arranged inside the barrel 1;

[0034] A hose is provided between the cylinder 1 and the feed port of the rocking screen to prevent the vibration of the rocking screen from being transmitted to the cylinder 1. The cylinder 1 can be fixed at the feed port of the rocking screen by means of a frame or hoisting.

[0035] In actual use, after adding materials into the barrel 2, the material distribution component 3 is started, and the material distribution component 3 drives the barrel 2 to rotate inside the cylinder 1. Since the discharge port of the barrel 2 is offset at the bottom of the barrel 2, the position of the discharge port will continue to change when the barrel 2 rotates. At the same time, the rotation of the barrel 2 will drive the discharge component 4 to move, thereby realizing the operation mode of discharging materials while the barrel 2 rotates. This linkage mechanism allows the material to be evenly distributed on the screen of the swing screen through the dynamically changing discharge port, preventing the material from being continuously concentrated at a certain position of the screen, resulting in central accumulation.

[0036] Since the discharge port of the barrel 2 is offset at the bottom, the position of the discharge port changes continuously during rotation, forming a circular distribution track. By adjusting the shape, area and angle of the discharge port, the uniformity of material distribution on the screen can be optimized. To ensure uniform coverage when the material is discharged, the width of the discharge port should not be too large to avoid concentrated falling of the material.

[0037] See also Figure 2 , which shows an embodiment of the cloth assembly 3, the cloth assembly 3 includes a gear ring 31 fixedly connected to the barrel 2, a motor 33 is installed on the outside of the barrel 1, a gear shaft 32 is fixedly connected to the output shaft of the motor 33, and the gear shaft 32 and the gear ring 31 are meshed; after the motor 33 is started, the gear ring 31 is driven to rotate through the gear shaft 32, thereby driving the barrel 2 to rotate.

[0038] See also Figures 2 - 7, which shows an embodiment of the blanking assembly 4. The blanking assembly 4 includes a shaft body 41 rotatably arranged inside the material cylinder 2 and a ring 43 fixedly connected inside the cylinder body 1; an external rotor 42 is fixedly connected to the shaft body 41, and grooves are formed on the rotor 42. After rotation, the rotor 42 can discharge the materials inside the material cylinder 2; a connection groove 48 is formed inside the shaft body 41, and a connecting rod 47 is inserted into the connection groove 48. One end of the connecting rod 47 is fixedly connected with a worm gear 46. After the worm gear 46 rotates, the shaft body 41 is driven to rotate through the connecting rod 47; the worm gear 46 is meshed with a worm 45, and the worm 45 is fixedly connected to a driving wheel 44, and the driving wheel 44 is attached to the inner side of the ring 43; the worm 45 and the worm gear 46 are arranged outside the housing 410; the surface of the driving wheel 44 can be set as a relatively rough surface, and correspondingly, the ring 43 is set as a relatively rough surface; a tooth-shaped structure can also be arranged on the surface of the driving wheel 44, and correspondingly, the ring 43 is made of rubber material; the purpose of the above settings is to ensure the friction between the driving wheel 44 and the ring 43, so that the driving wheel 44 can rotate self - synchronously under the action of the ring 43 when it revolves.

[0039] There are two implementation methods for the position setting of the housing 410:

[0040] When the housing 410 is fixedly connected to the outside of the material cylinder 2 (not shown in the figure), the rotational movement of the material cylinder 2 will drive the driving wheel 44 to revolve along the axis of the material cylinder 2. During the revolution, the driving wheel 44 and the ring 43 generate a frictional effect, forcing the driving wheel 44 to rotate self - synchronously at the same time. The self - rotation of the driving wheel 44 drives the worm 45 to rotate through the transmission mechanism. The worm 45 and the worm gear 46 are meshed and transmitted, so that the worm gear 46 rotates synchronously. The worm gear 46 drives the shaft body 41 to rotate through the connecting rod 47, and then drives the rotor 42 to operate, finally realizing the function of uniformly discharging the materials inside the material cylinder 2. This mechanism converts the main rotational movement of the material cylinder 2 into the driving power of the rotor 42 through the revolution - self - rotation conversion mechanism, realizing the synchronous operation of rotary blanking;

[0041] When the housing 410 is movably arranged outside the material cylinder 2 (such as Figure 7As shown in the figure, at this time, a first spring 49 sleeving the outside of the connecting rod 47 is arranged between the outer shell 410 and the barrel 2. A limiting rod 411 penetrating the inside of the outer shell 410 is fixedly connected to the outside of the barrel 2, and a second spring 412 located between the outer shell 410 and the barrel 2 is sleeved on the outside of the limiting rod 411. The rotational movement of the barrel 2 will drive the driving wheel 44 to revolve along the axis of the barrel 2. During the revolution, the first spring 49 and the second spring 412 provide pressure to the driving wheel 44, so that the driving wheel 44 presses on the circular ring 43, and a frictional effect is generated between the driving wheel 44 and the circular ring 43, forcing the driving wheel 44 to generate a rotational movement at the same time. The rotation of the driving wheel 44 drives the worm 45 to rotate through the transmission mechanism, and the worm 45 is meshed with the worm gear 46 for transmission, so that the worm gear 46 rotates synchronously. The worm gear 46 drives the shaft body 41 to rotate through the connecting rod 47, and then drives the rotor 42 to operate, and finally realizes the function of uniformly discharging the materials inside the barrel 2;

[0042] The design of movably arranging the outer shell 410 outside the barrel 2 aims to realize the dual adjustment of the rotation speed of the rotor 42 (i.e., the discharging speed of the barrel 2):

[0043] 1. Rotation speed linkage adjustment:

[0044] The rotation speed of the barrel 2 directly affects the feeding speed - the faster the rotation speed of the barrel 2, the faster the revolution speed of the driving wheel 44 will be synchronously. Through frictional transmission, the rotation speed of the driving wheel 44 is accelerated, and then the rotation speed of the worm 45 - worm gear 46 transmission system is increased. Finally, the rotation speed of the rotor 42 is increased, realizing a linear increase in the feeding speed.

[0045] 2. Height mechanical adjustment:

[0046] By adjusting the vertical position of the barrel 2, the feeding speed can be changed - when the barrel 2 moves downward, it drives the outer shell 410 and the conical driving wheel 44 to move downward synchronously, so that the contact position between the driving wheel 44 and the circular ring 43 moves outward (equivalently increasing the working diameter of the driving wheel 44); at the same rotation speed of the barrel 2, the linear speed of the driving wheel 44 remains unchanged, but due to the increase in the working diameter, its angular speed of rotation decreases, resulting in the deceleration of the worm 45 - worm gear 46 system, and finally reducing the rotation speed of the rotor 42 and the discharging speed; on the contrary, moving the barrel 2 upward can increase the discharging speed.

[0047] This design realizes the wide-range and precise control of the feeding speed through two independent adjustment mechanisms (rotation speed adjustment + height mechanical adjustment):

[0048] 1. Dynamic response adjustment: By adjusting the speed of the motor 33, the rotation speed of the barrel 2 is directly changed, which is suitable for rapid response requirements;

[0049] 2. Mechanical compensation adjustment: By adjusting the height, the transmission ratio at the driving wheel 44 is changed, which is suitable for fine constant speed requirements.

[0050] The dual adjustment method significantly expands the adaptability of the device to process requirements such as different material fluidity and screening accuracy.

[0051] See Figure 2 , which shows an embodiment of the drive assembly 7 for adjusting the vertical position of the cartridge 2 inside the cylinder 1. The drive assembly 7 includes a connecting frame 71. The cartridge 2 is rotatably connected inside the connecting frame 71. By using the electric push rod 72 provided on the cylinder 1 to push the connecting frame 71 to move, the height of the cartridge 2 can be adjusted.

[0052] As a further description of the feeding assembly 4: See Figure 3 , a baffle 8 with the same inner diameter as the cylinder 1 is fixedly connected to the discharge port of the cartridge 2. The outer diameter of the cartridge 2 is the same as the inner diameter of the cylinder 1, so that the space formed by enclosing between the baffle 8, the cartridge 2 and the inside of the cylinder 1 is used to enclose the feeding assembly 4 to prevent powdered materials from invading.

[0053] See Figures 3 - 4 , a feed pipe 5 is rotatably connected to the top of the cartridge 2. A stirring frame 6 extending into the inside of the cartridge 2 is fixedly connected inside the feed pipe 5. When the cartridge 2 rotates, the fixed feed pipe 5 does not rotate, so that the stirring frame 6 and the cartridge 2 rotate relative to each other, and the materials inside the cartridge 2 can be stirred by the stirring frame 6 to prevent the phenomenon of "bridging" of the materials, resulting in the inability of the materials to fall;

[0054] A hose is provided between the feed pipe 5 and the cartridge 2, so that the cartridge 2 can be adjusted in height normally.
