Description

Technical Field

[0001] This utility model relates to the technical field of abrasive sieving devices, specifically a precision abrasive sieving device. Background Technology

[0002] Sandblasting is a process that uses abrasives to impact and roughen the surface of a workpiece, resulting in a uniform finish without damaging the workpiece substrate. By selecting different abrasives and process parameters, surface roughness can be precisely controlled to meet various process requirements. It has a wide range of applications and can handle workpieces of various shapes and materials. The quality of sandblasted products largely depends on the purity of the abrasive. Therefore, the abrasive needs to be sieved before sandblasting. However, currently, abrasive sieving is done manually. Manual sieving is not only labor-intensive and time-consuming, but also inefficient, resulting in low purity of the sand and poor product quality. Utility Model Content

[0003] The purpose of this invention is to provide a precision abrasive sieving device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a precision abrasive sieving device, comprising a material distribution tank, a pouring plate fixedly installed on the top of the material distribution tank, a support base fixedly installed on the bottom of the material distribution tank, a connecting seat fixedly installed on the side of the material distribution tank, a damping rod fixedly connected to the side of the connecting seat, a rubber roller rotatably installed on the side of the damping rod, and multiple sets of guide hoppers fixedly connected to the top of the support base.

[0005] Preferably, a straight rod is fixedly installed on the top of the support base, a rotating sleeve is fixedly installed on the top of the straight rod, a classifying cylinder is rotatably installed on the inner side of the rotating sleeve, a collection trough is installed on the top of the support base and is located near the bottom of the classifying cylinder, and a collection box is installed at the bottom opening of the guide hopper.

[0006] Preferably, the side of the grading cylinder is in contact with the rubber roller and rotates. Multiple sets of connecting rods are fixedly installed on the inner side of the grading cylinder, and a rotating shaft is fixedly connected to the side of the connecting rod away from the grading cylinder. A drive motor is fixedly installed on the top of the rotating shaft.

[0007] Preferably, the grading cylinder is fixedly provided with a first sieving zone, a second sieving zone, and a third sieving zone on its side, and the first sieving zone, the second sieving zone, and the third sieving zone are equidistantly arranged on the circumferential side of the grading cylinder.

[0008] Preferably, three sets of auger blades are fixedly connected to the side of the rotating shaft. The three sets of auger blades are respectively installed inside the first screening zone, the second screening zone and the third screening zone, and the auger blades are built inside the grading cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the design of the drive motor, rotating shaft, grading cylinder, and rotating sleeve, the drive motor can synchronously drive the grading cylinder to rotate inside the rotating sleeve via the rotating shaft, enabling continuous feeding and discharging to meet the needs of large-scale production. The material is continuously lifted and fallen within the rotating cylinder as the cylinder rotates, forming multiple screening processes, which effectively improves screening efficiency and accuracy, allowing abrasives of different particle sizes to be separated more accurately. By setting up a damping rod, connecting seat, and rubber roller structure, the rubber roller can fit against the grading cylinder, pushing out abrasives stuck in the screening holes, preventing blockage and affecting screening efficiency. Through the auger fan blade structure design, the flow rate of the abrasive can be limited when the rotating shaft rotates synchronously, pushing some material back to a higher position, preventing excessively fast material flow from falling into other screening areas and causing contamination, thus improving screening accuracy.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1: Please refer to Figures 1-3This utility model provides a technical solution: a precision abrasive sieving device, including a material distribution tank 1, a pouring plate 2 fixedly installed on the top of the material distribution tank 1, a support base 3 fixedly installed on the bottom of the material distribution tank 1, a connecting base 4 fixedly installed on the side of the material distribution tank 1, a damping rod 5 fixedly connected to the side of the connecting base 4, a rubber roller 6 rotatably installed on the side of the damping rod 5, and multiple sets of guide hoppers 7 fixedly connected to the top of the support base 3. The damping rod 5 pushes the rubber roller 6 to conform to the grading cylinder 10. The rubber roller 6 has strong plasticity and can penetrate deep into the sieving holes to push out the abrasive stuck in the sieving holes, avoiding the sieving holes from being blocked and affecting the sieving efficiency.

[0016] A straight rod 8 is fixedly installed on the top of the support base 3, a rotating sleeve 9 is fixedly installed on the top of the straight rod 8, a classifying cylinder 10 is rotatably installed on the inner side of the rotating sleeve 9, a collection trough 11 is installed on the top of the support base 3, and the collection trough 11 is located near the bottom of the classifying cylinder 10. A collection box 12 is installed at the bottom opening of the guide hopper 7.

[0017] The side of the grading cylinder 10 is in contact with the rubber roller 6 and rotates. Multiple sets of connecting rods 13 are fixedly installed on the inner side of the grading cylinder 10, and a rotating shaft 14 is fixedly connected to the side of the connecting rod 13 away from the grading cylinder 10. A drive motor 15 is fixedly installed on the top of the rotating shaft 14. The side of the grading cylinder 10 is fixedly provided with a first screening area 16, a second screening area 17, and a third screening area 18, and the first screening area 16, the second screening area 17, and the third screening area 18 are equidistantly arranged on the circumferential side of the grading cylinder 10. The drive motor 15 can synchronously drive the grading cylinder 10 to rotate inside the rotating sleeve 9 through the rotating shaft 14, which can continuously feed and discharge materials to meet the needs of large-scale production. The material is continuously lifted and fallen inside the rotating cylinder as the cylinder rotates, forming multiple screening processes, which can effectively improve screening efficiency and accuracy.

[0018] Three sets of auger blades 19 are fixedly connected to the side of the rotating shaft 14. The three sets of auger blades 19 are respectively installed inside the first screening zone 16, the second screening zone 17 and the third screening zone 18, and the auger blades 19 are built inside the grading cylinder 10. The auger blades 19 are designed to limit the flow of abrasive when the rotating shaft 14 rotates synchronously, pushing some of the material back to a higher position, avoiding the material flow rate from falling into other screening zones and causing pollution due to excessively fast material flow, and improving the accuracy of screening.

[0019] In use, first, start the drive motor 15, then pour the abrasive into the top of the pouring plate 2. The drive motor 15 can synchronously drive the classifying cylinder 10 to rotate inside the rotating sleeve 9 through the connecting rod 13 and the rotating shaft 14. The material is continuously lifted and fallen in the rotating cylinder as the cylinder rotates, forming multiple screening processes, which can effectively improve screening efficiency and accuracy. During the rotation of the classifying cylinder 10, the rubber roller 6 can fit against the classifying cylinder 10 and push out the abrasive stuck in the screening holes, avoiding the screening holes from being blocked. Through the structure design of the auger fan blade 19, the flow rate of the abrasive can be limited when the rotating shaft 14 rotates synchronously, pushing some of the accumulated material back to a higher position for repeated screening. The screened abrasive will fall from the first screening area 16, the second screening area 17 and the third screening area 18 into the guide hopper 7, and then flow into the collection box from the opening at the bottom of the guide hopper 7, completing the precision screening of the abrasive.
