Technical Field

[0001] This utility model relates to the field of automated teaching technology, specifically a particle counting and filling teaching module. Background Technology

[0002] In the field of automated teaching, especially in operations involving particle screening, counting, and filling, traditional teaching equipment has many shortcomings. Existing teaching modules are often complex in structure and inconvenient to operate, making it difficult to meet students' needs for intuitive learning and hands-on practice.

[0003] On the one hand, traditional particle screening equipment has relatively limited functionality, only capable of performing simple screening operations and lacking precise control and monitoring of the screening process. For example, it cannot count the number of particles after screening in real time, nor can it flexibly adjust screening settings based on particle size, which makes the teaching process lack interactivity and practicality.

[0004] On the other hand, the existing equipment lacks sufficient disassembly and flexibility. During the teaching process, students need to understand the working principle of the equipment by disassembling and assembling it, but the existing equipment is often difficult to disassemble and assemble quickly. This not only affects teaching efficiency, but may also cause damage to the equipment due to improper disassembly and assembly.

[0005] Furthermore, the existing equipment has a low level of integration, with components scattered throughout, making it difficult for students to intuitively understand the collaborative relationships between these components. This not only increases the difficulty of teaching but also hinders students' overall understanding of automated systems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a particle counting and filling teaching module, which is compact, easy to operate, flexibly disassembled and assembled, and highly integrated, so as to improve teaching effectiveness and students' learning interest.

[0008] A further technical solution includes a screening and feeding assembly comprising a hopper, a screen plate seat at the bottom of the hopper, a screen plate rotatably mounted in the screen plate seat, a drop hole in the screen plate seat, and multiple screen holes in the screen plate. A particle hopper is mounted at the top of the hopper, and a particle hopper cover is snapped onto the top of the particle hopper. A power structure for driving the screen plate to rotate is also provided on one side of the hopper. The drop hole is positioned opposite to the guide cylinder.

[0009] In a further technical solution, a tongue is also provided inside the hopper, and the tongue is located on the upper side of the screen plate.

[0010] In a further technical solution, the top of the silo is provided with a detachable adapter, and the pellet bin is snapped into the adapter.

[0011] A further technical solution includes a power structure comprising a rotating shaft that is poweredly connected to the screen disc, the rotating shaft rotatably passing through the screen disc base, a driven pulley fixedly disposed on the outer surface of the rotating shaft, and a planetary reduction stepper motor, a driving pulley fixedly disposed on the outer surface of the output shaft of the planetary reduction stepper motor, and a synchronous belt wound around the outer surfaces of the driving pulley and the driven pulley, the synchronous belt powerly connecting the driving pulley and the driven pulley.

[0012] In a further technical solution, optical fiber heads are provided on the front and rear sides of the hopper, and an optical fiber sensor is also included, wherein the optical fiber sensor is electrically connected to the optical fiber head.

The terminal and the stepper motor controller are fixed on both sides of the column.

[0017] The beneficial effects of this utility model are as follows: First, this module integrates a stand, a screening and feeding component, a guide cylinder, and a counting grating. By loading particles of different diameters into the screening and feeding component, the counting grating counts the number of particles in the guide cylinder. The compact design of this module facilitates easy assembly and disassembly by personnel. In actual teaching activities, screens with different diameter holes can be replaced to achieve different screening effects, allowing personnel to improve the automation learning effect through hands-on operation.

[0041] Advantageously, the detachable connection between the hopper 23 and the screen plate seat 46 is achieved by providing a through hole 47 in the hopper 23, installing a fastener in the through hole 47, and connecting the fastener to the screen plate seat 46 by threaded engagement.

[0042] Advantageously, the planetary reducer stepper motor 12 is fixedly mounted on the platform plate 13, the screen plate seat 46 is fixedly mounted on the platform plate 13, and the platform plate 13 is also provided with through holes corresponding to the falling holes 35 to facilitate the passage of particles through the platform plate 13.

[0044] This module integrates a stand, a screening and feeding assembly, a guide cylinder 19, and a counting grating 21. By loading particles of different diameters into the screening and feeding assembly, the assembly filters particles smaller than or equal to the diameter of the sieve holes 43, which then fall along the guide cylinder 19. During this process, the counting grating 21 counts the number of particles in the guide cylinder 19. The module's compact design allows for easy assembly and disassembly. In actual teaching activities, the sieve discs 41 with different diameter sieve holes 43 can be replaced to achieve different screening effects, allowing personnel to improve the automation learning effect through hands-on operation.

[0045] When learning to use this teaching module, the personnel remove the pellet bin cover 31 from the top of the pellet bin 32, and then load pellets of different diameters into the pellet bin 32. The pellets enter the upper surface of the screen plate 41 inside the hopper 23 and accumulate. The fiber optic head 14 is used to transmit the optical signal of the fiber optic sensor 15. After the fiber optic sensor 15 works, it reads the physical characteristics of the pellets. Then, the personnel start the planetary reduction stepper motor 12 through the stepper motor controller 18. The planetary reduction stepper motor 12 drives the drive pulley 25 to rotate. Under the power connection of the synchronous belt 24, the driven pulley 28 drives the rotating shaft 36 to rotate. Since the rotating shaft 36 is fixedly connected to the screen plate 41, it can drive the screen plate 41 to rotate. During the rotation, since the tongue 33 is set on the upper side of the screen plate 41, it pushes out the pellets larger than the screen holes 43 from the upper side of the screen holes 43. After the pellets smaller than the screen holes 43 enter the screen holes 43, the screen holes 43 can move the pellets on the upper surface of the screen plate seat 46.

[0046] When a particle smaller than the sieve hole 43 is opposite the drop hole 35, the particle falls from the drop hole 35 into the guide cylinder 19 and slides downward. Since the guide cylinder 19 is made of transparent material, after passing through the counting grating 21, the counting grating 21 can be triggered to count.

[0047] For the tongue 33, it can be adjusted up and down. That is, the screw 45 is disengaged from the hopper 23 and fixed by threading. After adjusting the up and down position of the tongue 33, the screw 45 is re-passed through the mounting groove 51 and re-threadedly connected and fixed to the hopper 23.

[0048] Since the adapter 42 can be detached from the hopper 23, personnel can adjust the tongue 33 after the adapter 42 is removed.

[0049] When replacing the screen plate 41, the fasteners in the through hole 47 are removed to separate the hopper 23 from the screen plate seat 46. Then, the set bolts between the rotating shaft 36 and the screen plate 41 are removed, the screen plate 41 is taken out upwards, and then a screen plate 41 with other specifications of screen holes 43 is replaced. The screen plate 41 is then re-fixed on the outer surface of the rotating shaft 36, and then the hopper 23 is re-fixed to the screen plate seat 46.

[0050] The top of the screen plate base 46 is provided with a circular boss, and a bearing is provided in the middle of the circular boss. The rotating shaft 36 passes through the inner ring of the bearing. When the fastener in the through hole 47 is installed and fixed to the screen plate base 46, it is fixed to the circular boss on the top of the screen plate base 46.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
