Description

Technical Field

[0001] This utility model relates to the field of roller screen technology, specifically a roller screen. Background Technology

[0002] A roller screen is a commonly used screening device, whose core component is a series of parallel rollers. These rollers are usually supported by bearings and can rotate flexibly within the frame. The diameter and length of the rollers depend on the specific application and the characteristics of the material being processed. For example, in roller screens that process larger pieces of material, the roller diameter may be larger to withstand greater impact forces; while for roller screens that screen fine particles, the roller diameter can be relatively smaller.

[0003] Currently, during operation, the rollers on the inner wall of the roller screen rotate continuously. When in use, the user throws the material onto the surface of the rollers to achieve the purpose of material transportation. In this process, some fragments inevitably adhere to the screen plates of the roller screen, which will inevitably lead to blockage over time. Therefore, a new type of roller screen is needed to solve the above problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides a roller screen, mainly to solve the problem that in current roller screens, the inner wall rollers rotate continuously during operation. When using the screen, the user throws material onto the roller surface to achieve the purpose of material transportation. However, during this process, some debris inevitably adheres to the screen plates, leading to clogging over time. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0024] A roller screen includes a roller screen body 1. During use, the user needs to install several steel wire ropes 2 below several rollers on the roller screen body 1 via a first limiting unit 3. As the rollers of the roller screen body 1 rotate, the steel wire ropes 2 continuously scrape against the surfaces of the rollers, causing debris to adhere to the surfaces of the rollers and resulting in roller blockage. The first limiting unit 3 is mainly composed of: [missing information - likely referring to a component or element]. In use, the user first slides a clip 34 into the inner wall of each of the limiting grooves 33 opened on the top of the mounting plate 31 (the clips 34 are used to limit the position of the wire ropes 2 above the mounting plate 31 respectively). The clips 34 are limited by the second limiting unit 35. Then, the mounting plate 31 is installed on the inner wall of the roller screen body 1 by the mounting unit 32, so as to limit the position of the wire ropes 2 under the roller screen body 1.

[0025] By setting several steel wire ropes 2 below several rollers of the roller screen body 1, during use, the user first restricts the steel wire ropes 2 below several rollers of the roller screen body 1 through the first limiting unit 3. When the rollers of the roller screen body 1 rotate, one end of the steel wire ropes 2 will continuously scrape the surface of the rollers of the roller screen body 1, thereby avoiding the situation where the rollers are blocked due to debris adhering to the surface of the rollers of the roller screen body 1.

[0026] By providing a mounting protrusion 322 on the surface of the mounting plate 31, the user can first place the mounting plate 31 below several rollers of the roller screen body 1 during installation. The mounting protrusion 322 then slides into the inner wall of the roller screen body 1. Finally, several mounting bolts 321 are threaded into the surface of the mounting plate 31, ensuring that all bolts 321 are threaded into the surface of the roller screen body 1, thus achieving the installation of the mounting plate 31 on the inner wall of the roller screen body 1.

[0027] like Figure 1 and Figure 2 As shown, in some embodiments, the main components of the mounting unit 32 are: mounting protrusions 322 provided on the surface of the mounting plate 31. In use, the user first inserts the mounting protrusions 322 into the inner wall of the roller screen body 1, and then inserts several mounting bolts 321 into the surface of several mounting plates 31, so that the surface of several mounting bolts 321 is threaded into the surface of the roller screen body 1, thereby realizing the installation of the mounting plate 31 on the inner wall of the roller screen body 1.

[0028] like Figure 4 and Figure 5As shown, in some embodiments, the main components of the plurality of clips 34 are: a plurality of sliders 341 that are respectively slidably inserted into the inner walls of a plurality of limiting grooves 33. In use, the user first slides a plurality of steel wire ropes 2 into the inner walls of a plurality of receiving grooves 342 respectively opened on the top of the plurality of sliders 341. A plurality of abutment blocks 343, driven by a drive unit 344, move, causing the surfaces of the abutment blocks 343 to abut against the surfaces of the plurality of steel wire ropes 2, thereby limiting the movement of the plurality of steel wire ropes 2 within the inner walls of the plurality of receiving grooves 342. The main components of the drive unit 344 are... The device consists of several drive threaded rods 3441 that are rotatably inserted into the surfaces of several abutment blocks 343. Simultaneously, the surfaces of these drive threaded rods 3441 are threaded into the surfaces of several sliders 341. Therefore, during use, the user rotates the drive threaded rods 3441, causing the abutment blocks 343 to slide along the inner walls of several receiving grooves 342. During this process, several guide protrusions 3442, each set on the surface of one abutment block 343, slide along the inner walls of several guide grooves 3443 that are respectively opened in the inner walls of the receiving grooves 342, effectively ensuring the stability of the abutment blocks 343 during sliding.

[0029] like Figure 4 and Figure 5 As shown, in some embodiments, the main components of the second limiting unit 35 are: several abutting nuts 352. In use, the user first slides several sliders 341 into the inner walls of several limiting grooves 33, and then slides several limiting rods 351, which are fixedly installed on the surfaces of several sliders 341, into the inner walls of several limiting grooves 33. Finally, abutting nuts 352 are threaded onto the surfaces of several limiting rods 351, thereby limiting the several sliders 341 in the inner walls of several limiting grooves 33. Since two picking grooves 4 are opened on the surface of the mounting plate 31, when it is necessary to move the mounting plate 31, two people need to hold the two picking grooves 4 respectively to lift and move the mounting plate 31.

[0030] The working process of this utility model is as follows: First, the user needs to place several steel wire ropes 2 on the inner wall of several receiving grooves 342 respectively, rotate several drive threaded rods 3441 so that several abutting blocks 343 abut against the surface of several steel wire ropes 2 respectively, and then insert the mounting plate 31 into the inner wall of the roller screen body 1 so that the surface of the mounting protrusion 322 slides into the inner wall of the roller screen body 1. The surfaces of several mounting bolts 321 are threaded into the mounting plate 31 and the surface of the roller screen body 1, which can realize the limitation of several steel wire ropes 2 under several rollers of the roller screen body 1. In subsequent use, some fragments attached to several rollers of the roller screen body 1 can be removed, and several steel wire ropes 2 can also be removed.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
