Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically to a vibrating screening device for PVC sheath material. Background Technology

[0002] PVC sheath material is an insulating material used in cable manufacturing. Its main component is polyvinyl chloride. It is produced by pressing the sheath material onto a multi-strand copper wire conductor through a high-tech automated production line to form a flat cable.

[0003] PVC sheathing material has advantages such as softness, easy bending and folding, relatively thinness, small size, simple connection, and convenient disassembly. It is widely used in control units with reciprocating movement requirements. However, in the production process of PVC sheathing material, it is necessary to screen PVC particles of different sizes and grades, which requires the use of PVC particle screening devices. However, after the existing screening devices are used, a small number of PVC particles will clog the screen. In the later process of unblocking, workers always need to manually unblock the clogged areas with tools, which is inefficient and inconvenient. Utility Model Content

[0004] Based on the above description, this utility model provides a vibrating screening device for PVC sheath material to solve the problem of inconvenience in the later stage of PVC particle screening device when clearing the screen.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A PVC sheath material vibrating screening device includes a base plate, a vibrating frame and a vibrating motor. The vibrating frame is located above the base plate. Several springs are provided between the vibrating frame and the base plate. The vibrating motor is installed on the vibrating frame. A connecting frame is movably connected to the inner side of the vibrating frame. A screen is provided on the connecting frame. A connecting plate is provided on the vibrating frame. A brush is provided on the bottom surface of the connecting plate.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the screen is located directly below the brush, and the screen has an arc-shaped design.

[0008] Furthermore, a drive motor is provided on one side of the vibration frame, and the output end of the drive motor is connected to one side of the connecting frame.

[0009] Furthermore, the top surface of the base plate is provided with a concave frame, which is located directly below the screen, and the top surface of the concave frame is provided with a receiving frame.

[0010] Furthermore, the top surface of the concave frame is provided with a groove, and the receiving frame is movably engaged in the groove.

[0011] Furthermore, threaded holes are provided on both the left and right sides of the vibration frame, and the connecting plate is connected to the vibration frame by bolts.

[0012] Furthermore, a rubber ring is provided between the bolt and the connecting plate.

[0013] Furthermore, the surface of the vibration frame is provided with a slot, and the surface of the connecting plate is provided with a protrusion that extends into the slot.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] 1. By connecting the connecting frame with the screen to the vibrating frame, and setting a connecting plate on the vibrating frame with a brush on the connecting plate, when the screen needs to be cleared, the operator only needs to rotate the connecting frame to clear the screen blockage. This makes the screen clearing process simpler, faster, more convenient, and more practical.

[0016] 2. By drilling threaded holes in the vibration frame and connecting the connecting plate to the vibration frame with bolts, the connecting plate and the vibration frame can be disassembled separately, which facilitates the replacement of the brushes later and avoids the situation where the brushes cannot be disassembled and replaced after long-term use and when they fall off.

[0026] Example

[0027] Please refer to Figures 1-5 This embodiment provides a vibrating screening device for PVC sheath material, including a base plate 1, a vibrating frame 2, and a vibrating motor 4. The vibrating frame 2 is located above the base plate 1, and multiple springs 3 are provided between the vibrating frame 2 and the base plate 1. The vibrating motor 4 is mounted on the vibrating frame 2 and is used to output vibration to the vibrating frame 2. A connecting frame 5 is rotatably connected to the inner side of the vibrating frame 2, and a screen 6 is provided on the connecting frame 5. The screen 6 has an arc-shaped design. A connecting plate 7 is provided on the vibrating frame 2, and a brush 8 is provided on the bottom surface of the connecting plate 7. The screen 6 is located directly below the brush 8.

[0028] In this embodiment, when it is necessary to clean the screen 6, the operator can apply pressure and rotate the connecting frame 5. During the rotation, the connecting frame 5 first contacts the brush 8 on the bottom surface of the connecting plate 7. The brush 8 deforms under the pressure of the connecting frame 5, and then continues to rotate and apply pressure, so that the protruding surface of the screen 6 with its arc design contacts the surface of the brush 8, until the screen 6 is rotated one revolution, thereby using the brush 8 to scrape and unclog the screen 6.

[0029] As an optional implementation, a drive motor 9 is provided on one side of the vibration frame 2, and the output end of the drive motor 9 is connected to one side of the connecting frame 5. The drive motor 9 is connected to an external power source.

[0030] In this embodiment, the drive motor 9 is powered on and started, and the drive motor 9 drives the connecting frame 5 to rotate, thereby realizing the automated processing of unblocking the screen 6.

[0031] As an optional implementation, the top surface of the base plate 1 is provided with a concave frame 10, which is located directly below the screen 6, and the top surface of the concave frame 10 is provided with a receiving frame 11.

[0032] In this embodiment, the worker pours the PVC granules to be screened onto the screen 6, starts the vibration motor 4, and the vibration motor 4 outputs vibration to the vibration frame 2, so that the PVC granules on the screen 6 are vibrated and screened. The screened PVC granules fall into the receiving frame 11 for collection, which is convenient for subsequent unified processing.

[0033] As an optional implementation, the top surface of the concave frame 10 is provided with a groove 101, and the receiving frame 11 is movably engaged in the groove 101.

[0034] In this embodiment, by placing the receiving frame 11 in the groove 101 opened in the concave frame 10, the receiving frame 11 is restricted, ensuring that the receiving frame 11 is always directly below the screen 6.

[0035] As an optional implementation, threaded holes 21 are provided on both the left and right sides of the vibration frame 2, and the connecting plate 7 is connected to the threaded holes 21 of the vibration frame 2 by bolts 12.

[0036] In this embodiment, the connecting plate 7 and the vibration frame 2 are connected by bolts 12, so that the connecting plate 7 and the vibration frame 2 can be disassembled and assembled, which facilitates the subsequent maintenance or replacement of the brush 8.

[0037] As an optional implementation, a rubber ring 13 is provided between the bolt 12 and the connecting plate 7.

[0038] In this embodiment, the rubber ring 13 makes the connection between the bolt 12 and the connecting plate 7 and the vibrating frame 2 more stable, thus preventing the bolt 12 from loosening during the vibrating screening process.

[0039] As an optional implementation, the surface of the vibration frame 2 is provided with a slot 22, and the surface of the connecting plate 7 is provided with a protrusion 71 that protrudes into the slot 22.

[0040] In this embodiment, the disassembled connecting plate 7 is placed on the vibration frame 2 using the protrusion 71, which ensures the position of the connecting plate 7 on the vibration frame 2 and is more conducive to the connection and fixation between the connecting plate 7 and the vibration frame 2 by bolts 12.
