Description

Technical Field

[0001] The utility model relates to the technical field of screening and sorting devices, in particular to a screening separator. Background Art

[0002] Columnar materials are often involved in mechanical processing. Columnar materials are placed in a material box in a random order. During processing, the columnar materials need to be arranged in order and fed one by one. At present, the automatic sorting and feeding device for columnar materials in the industry mainly adopts a vibrating feeding device with a vibration motor and a vibration plate as the main body. The device generates noise of more than 70 decibels during the vibration feeding process, which invisibly affects the workshop environment and the work efficiency of workers.

[0003] Moreover, when screening miniature columnar parts, the existing vibrating feeding equipment cannot maintain the consistency of the sorting of the screened columnar parts, and the materials are prone to accumulation and discharge; as the materials slide down the inner angle slide of the drum, some materials enter the next screening link before being thoroughly screened, resulting in incomplete screening and sorting, reducing the screening efficiency, and easily leading to the inability to ensure the consistency of material sorting, making the sorting channel easily blocked and the screening effect poor. Utility Model Content

[0004] The purpose of the utility model is to provide a screening separator, which can solve the problems raised by the above-mentioned background technology in view of the deficiencies of the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The utility model provides a screening separator, comprising a mounting frame, a screening assembly being arranged on the mounting frame, the screening assembly comprising a screening funnel mounted on the top of the mounting frame, a screening pipe being slidably arranged on the mounting frame along a vertical direction, a guide pipe being arranged on the small diameter end of the screening funnel, the screening pipe being slidably arranged in the guide pipe, and a driving assembly being arranged on the mounting frame for driving the screening pipe to reciprocate along a vertical direction.

[0007] In some technical solutions of the utility model, the driving assembly includes a cylinder installed on a mounting frame, and the output end of the cylinder is drivingly connected to the screening pipe.

[0008] Some technical solutions of the utility model also include a guide seat installed on the mounting frame, a guide frame is slidably provided in the guide seat, a connecting frame connected to the screening pipe is provided on the guide frame, and the pushing end of the cylinder is drivingly connected to the connecting frame.

[0009] In some technical solutions of the utility model, a tension spring connected to the guide frame is provided on the mounting frame.

[0010] In some technical solutions of the utility model, the pushing end of the cylinder abuts against the connecting frame.

[0011] In some technical solutions of the present utility model, there are multiple groups of screening components, and the multiple groups of screening components are all installed on the mounting frame.

[0012] In some technical solutions of the utility model, a control device connected to the cylinder signal is installed on the top of the mounting frame.

[0013] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0014] The screening tube gradually enters the screening funnel under the guidance of the guide tube and makes reciprocating motion in the screening funnel; at this time, the screening tube also impacts the columnar material in the screening funnel. At this time, the chaotic material in the screening funnel is affected by the up and down movement of the screening tube, the vibration generated by the impact of the screening tube when it contacts the material, and the principle that the materials are aligned with each other through their own characteristics after the materials are squeezed and contacted. The material uses its own falling force to fall into the screening tube, and then is discharged into the screening funnel along the screening tube, thereby realizing the screening and sorting of the material, and avoiding the problem of the screening tube being blocked;

[0015] The tension spring can pull the guide frame to move in the vertical direction in the slideway of the guide seat close to the screening funnel, so that the screening tube moves up and down in the screening funnel and exerts an impact force on the material, so that the materials are pushed, vibrated, and squeezed into contact with each other through the principle of mutual alignment through their own characteristics, so that the materials use the downward force generated by themselves to fall into the screening tube, thereby achieving the effect of moving and separating the materials.

Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] Please refer to Figure 1-Figure 3 shown.

[0025] The utility model provides a screening separator, such as Figure 1 , Figure 2As shown in the figure, it includes a mounting frame 1. A screening component is provided on the mounting frame 1. The screening component includes a screening funnel 2 installed at the top of the mounting frame 1. The screening funnel 2 is in the shape of a conical cylinder. A screening pipe 5 is slidably arranged on the mounting frame 1 in the vertical direction. A guiding pipe 12 is provided at the small-diameter end of the screening funnel 2. The screening pipe 5 is slidably arranged inside the guiding pipe 12. A driving component for driving the screening pipe 5 to reciprocate in the vertical direction is provided on the mounting frame 1. The mounting frame 1 set in this technical solution is made of a frame structure, which can provide a bearing area for the screening component and ensure the stability of the operation of this equipment. And the provided screening funnel 2 is installed at the top of the mounting frame 1 through a prefabricated part 4 in the shape of a "C". The mounting frame 1 and the prefabricated part 4 are fixed together by screws. An installation opening adapted to the screening funnel 2 is opened on the horizontal section at the top in the prefabricated part 4. The screening funnel 2 is located in the installation opening and is fixed on the prefabricated part 4 by welding or bolt connection. A through groove adapted to the screening pipe 5 is also opened on the horizontal section at the lower part in the prefabricated part 4, which plays a guiding role in the reciprocating movement of the screening pipe 5 in the vertical direction. When the above structure is installed, start the driving component. At this time, the driving component will push the screening pipe 5 to move reciprocally in the vertical direction. At this time, the screening pipe 5 gradually enters the screening funnel 2 under the guidance of the guiding pipe 12 and reciprocates in the screening funnel 2. At this time, the screening pipe 5 also impacts the columnar materials located in the screening funnel 2. At this time, the materials in a disordered state in the screening funnel 2, under the action of the up-and-down movement of the screening pipe 5, the vibration generated by the impact when the screening pipe 5 contacts the materials, and the principle that the materials are aligned with each other through their own characteristics after the materials are squeezed and contacted, make the materials fall into the screening pipe 5 by their own gravity, and then are discharged from the screening funnel 2 along the screening pipe 5, so as to realize the screening and sorting of the materials and avoid the problem of blockage of the screening pipe 5.

[0026] Further, the screening pipe 5 is a transparent PC plastic pipe.

[0027] In some technical solutions of the present utility model, the driving component includes a cylinder 10 installed on the mounting frame 1. The output end of the cylinder 10 is传动连接 with the screening pipe 5. The provided cylinder 10 is a micro cylinder 10, which can be controlled by a PLC controller so that the opening and closing of the cylinder 10 are controlled. Through the above structure, the continuity of the screening pipe 5 when reciprocating in the vertical direction is ensured, and the continuous screening of the columnar materials by the above equipment is guaranteed, and the screening efficiency is improved.

[0028] It should be noted that the "传动连接" in the original text seems to be an incorrect expression. It might be "drivably connected" or something more appropriate. The above translation is based on the context as accurately as possible.In some technical schemes of the utility model, it also includes a guide seat 8 installed on the mounting frame 1 by bolts, a guide frame 9 is slidably provided in the slideway of the guide seat 8, a connecting frame 6 connected to the screening pipe 5 is provided on the guide frame 9, and the pushing end of the cylinder 10 is transmission-connected to the connecting frame 6, so that it can be ensured that the screening pipe 5 can make reciprocating motion in the vertical direction along a predetermined route under the guidance of the cylinder 10 and the guide frame 9, thereby ensuring the accuracy of the equipment.

[0029] Furthermore, the cylinder 10 can be mounted on the guide seat 8 via the mounting plate 11 .

[0030] In some technical solutions of the present utility model, the push end of the cylinder 10 abuts against the connecting frame 6. This can increase the instantaneous impact force applied by the cylinder 10 to the screening tube 5 and improve the vibration force of the screening tube 5 on the material.

[0031] In some technical solutions of the utility model, a tension spring 7 connected to the guide frame 9 is provided on the mounting frame 1. The tension spring 7 can provide a pulling force for the guide frame 9 that reciprocates in the vertical direction and the screening tube 5 connected to the guide frame 9, that is, after the telescopic end of the cylinder 10 is out of contact with the connecting frame 6, the tension spring 7 can pull the guide frame 9 to move close to the screening funnel 2 in the slideway of the guide seat 8 in the vertical direction, so that the screening tube 5 moves up and down in the screening funnel 2 and applies an impact force to the material, so that the materials are pushed, vibrated, and squeezed into contact with each other by the principle that the materials are aligned with each other through their own characteristics, so that the materials fall into the screening tube 5 using the falling force generated by themselves, and then the effect of moving and separating the materials is achieved.

[0032] After the pushing end of the cylinder 10 abuts against the connecting frame 6, it also avoids the effect of hindering the vibration of the screening tube 5 under the pull of the tension spring 7 after the cylinder 10 and the connecting frame 6 are rigidly connected, resulting in the vibration force generated by the screening tube 5 during the upward movement being insufficient to cause the material to turn after being applied to the material, thereby causing the problem of poor screening effect of the material in the subsequent screening process to become prominent.

[0033] In some technical solutions of the utility model, the number of screening assemblies is 4, and multiple screening assemblies are installed on the mounting frame 1. Multiple parts can be screened independently at the same time. When the material is screened by the above structure, a large amount of noise can be avoided, the environmental quality of the production environment can be improved, and the construction efficiency can be improved.

[0034] In some technical solutions of the present invention, a control device 3 connected to the cylinder 10 is installed on the top of the mounting frame 1. The control device 3 is a PLC controller in the prior art, which is convenient for the user to control the periodic movement of the cylinder 10.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
