Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening equipment, in particular to a filter screen for screening road reflective materials. Background Art
[0002] Road reflective material is an important component of traffic safety facilities. It can reflect light to remind pedestrians. Reflective materials need to be crushed during production so that they can be fully combined with the substrate in subsequent processing. However, the reflective particles formed by the spectroscopic material after crushing are of different sizes. Therefore, a screen is needed to remove impurities, irregular particles or particles that are too large or too small in the reflective particles to ensure the purity and consistency of the final product. However, particles of different shapes and sizes will have different movement trajectories and adhesion abilities when passing through the filter. Some particles with irregular shapes may be smaller at one end and larger at the other end. Therefore, they are easily stuck in the filter holes when passing through the filter holes, resulting in blockage. In particular, many filters are now installed inside the screening equipment. When the filter is blocked and affects the filtration of reflective particles, the filter needs to be removed from the equipment before the particles blocked on the filter can be cleaned. This cleaning method is more cumbersome and requires the screening work to be suspended, which is not conducive to improving the screening efficiency. In view of this, we propose a filter for screening road reflective materials. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the field of road traffic, reflective materials are widely used in traffic safety facilities such as traffic signs, signs, license plates, and car body reflective logos. In addition, reflective materials can also be used in various types of clothing, shoes and hats, bags, billboards and other fields to provide safety protection and warning effects. The main principle is to use coating, lamination, composite and other technical processes to implant high-refractive index glass beads or micro-prism structures on the surface of the material to form a functional composite material. When light shines on these materials, they can reflect light back to the light source, thereby producing a reflection phenomenon. This reflective effect is particularly significant at night or in low light conditions, which can effectively enhance people's recognition ability and improve road safety. In the processing of processed materials, it is necessary to remove impurities, irregular particles or particles that are too large or too small in the reflective particles through a screen to ensure the purity and consistency of the final product. The filter screen will continue to vibrate when it is running, and particles of different shapes and sizes will have different motion trajectories and adhesion abilities when passing through the filter screen, so some particles with irregular shapes or larger sizes are more likely to get stuck in the filter hole 2, causing blockage, and the existing filter screen is generally installed inside the screening equipment, which is very inconvenient to clean. Therefore, we propose the following solution.
[0022] Embodiment 1
[0023] Reference Figure 1-Figure 4A filter screen for screening road reflective materials mainly consists of a filter body 1 and mounting protrusions arranged around the filter body 1 for installation. The filter body 1 is provided with a plurality of filter holes 2 for screening road reflective materials. The filter body 1 is provided with a cleaning component 3 for cleaning particles that clog the filter holes 2. When the filter body 1 is installed, the filter body 1 can be installed inside the screening equipment through the cooperation of the mounting bolts arranged around it and the mounting protrusions. During operation, the reflective material is filtered through the filter holes 2 arranged thereon. When the filter body 1 is blocked during the screening process, it can be processed by the cleaning component 3 to minimize the influence of the blockage on the screening efficiency of the reflective particles.
[0024] The filter screen will generally vibrate during operation, but the movement trajectory and adhesion ability of particles of different shapes and sizes will be different when passing through the filter screen. Some particles with irregular shapes may be smaller at one end and larger at the other end. Therefore, they are easily stuck in the filter hole 2 when passing through the filter hole 2, causing blockage. Now many filter screens are installed inside the screening equipment. When the filter screen is blocked and affects the filtration of reflective particles, the filter screen needs to be removed from the equipment before the particles blocked on the filter screen can be cleaned. Based on the technical defects existing in the above scenario, this embodiment realizes the control of the movement of the cleaning roller 31 under the filter body 1 through the cooperation of the traction rope 1 35 and the traction rope 2 36, thereby realizing the cleaning of the filter hole 2, avoiding the step of removing the filter body 1, and improving the screening efficiency of the reflective particles to a certain extent. The detailed implementation method is as follows:
[0025] The cleaning assembly 3 includes a cleaning roller 31 arranged below the filter body 1, and a cleaning shaft 32 is coaxially fixed at both ends, one end of the cleaning shaft 32 is fixedly sleeved with two limiting rings 34, a traction drum 33 rotatably connected to the cleaning shaft 32 is provided between the two limiting rings 34, a traction rope 1 35 and a traction rope 2 36 are fixedly installed on the traction drum 33, and one end of the traction rope 1 35 and the traction rope 2 36 are slidably extended to the outside of the filter body 1, and a guide groove 37 for the traction drum 33 to slide is provided in the filter body 1. When the filter body 1 is installed, one end of the traction rope 1 35 and the traction rope 2 36 can be extended from the preset holes on the screening device, such as Figure 2As shown, the traction rope 1 35 forms a "U" shape in the guide groove 37. When the filter is blocked, the traction rope 1 35 can be pulled to cooperate with the traction drum 33 and the cleaning shaft 32 to drive the cleaning roller 31 to move under the filter body 1. During movement, the roller hairs arranged on the cleaning roller 31 will extend into the filter hole 2, and squeeze the particles blocked in the filter hole 2 during the movement to ensure the smooth flow of the filter hole 2. After cleaning, the traction rope 2 36 is pulled to pull the cleaning roller 31 back to its original position. The cleaning method in this embodiment is relatively simple and can be achieved by only pulling the traction rope 1 35 and the traction rope 2 36. Compared with the traditional cleaning method, many steps are reduced, the cleaning efficiency is greatly improved, and the screening speed of reflective particles is increased.
[0026] Both ends of the traction rope 1 35 and the traction rope 2 36 are provided with adsorption magnetic blocks 39 that can attract each other. The setting of the adsorption magnetic blocks 39 can allow the traction rope 1 35 and the traction rope 1 35, and the traction rope 2 36 and the traction rope 2 36 on both sides of the filter body 1 to be combined together. When pulling, the two ends of the cleaning roller 31 can be synchronously pulled together by the traction rope 1 35 or the traction rope 2 36, thereby improving the stability of the movement of the cleaning roller 31.
[0027] The left end of the guide groove 37 is provided with an arc groove for accommodating the cleaning roller 31. In order to facilitate the separation of the particles separated from the upper part of the filter body 1 from the filter body 1, in many screening devices, the filter body 1 is tilted so that the particles above can separate from the filter body 1 under the action of gravity. The setting of the arc groove makes it easier for the cleaning roller 31 to stay at the left end of the filter body 1 when the filter hole 2 is not cleaned. Figure 2 As shown, no filter hole 2 is provided above the arc groove, so no particles will fall onto the cleaning roller 31 during normal filtration.
[0028] Embodiment 2
[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that after the existing filter screen is blocked, the filter screen is generally removed from the screening equipment for cleaning, resulting in low screening efficiency. However, when the cleaning roller 31 cleans the blocked particles, some particles will fall into the gaps between the bristles on the cleaning roller 31 due to the action of gravity, and are not easy to separate from the cleaning roller 31 due to the clamping of the bristles, which will not only affect the cleaning of the filter hole 2 by the cleaning roller 31, but also cause a certain degree of waste of resources.
[0030] Reference Figure 1-Figure 4The guide groove 37 is provided with an operating groove on one side, and the cross section of the operating groove is consistent with that of the guide groove 37, and all dimensions are larger than that of the guide groove 37. A rotating assembly 38 for controlling the rotation of the cleaning roller 31 is provided in the operating groove. The rotating assembly 38 includes a rotating gear 381 fixedly mounted on one end of the cleaning shaft 32, and a rotating rack 382 meshing with the rotating gear 381 is fixedly mounted on the upper part of the operating groove. In this embodiment, the cleaning roller 31 is continuously rotated by arranging the rotating assembly 38, and the particles falling on the cleaning roller 31 are continuously thrown out by utilizing the centrifugal force. The specific operation is as follows: When the traction rope 35 pulls the cleaning roller 31 out of the arc groove, the horizontal height of the cleaning roller 31 is raised, and the rotating gear 381 coaxially fixed with the cleaning shaft 32 is meshed with the rotating rack 382. Therefore, during the movement of the cleaning roller 31, the rotating gear 381 is meshed with the rotating rack 382, which drives the cleaning roller 31 to rotate continuously, thereby achieving the effect of cleaning the filter hole 2 and external particles.
[0031] The diameter of the limiting ring 34 is smaller than that of the traction drum 33. The special setting of the diameters of the limiting ring 34 and the traction drum 33 allows the cleaning roller 31 to have only the traction drum 33 in contact with the guide groove 37 during its movement, thereby avoiding the friction resistance between the cleaning shaft 32 and the guide groove 37 affecting the rotation of the cleaning roller 31 and ensuring the stability of the cleaning work of the filter hole 2.
[0032] The filter hole 2 has a conical structure, and its internal dimensions increase in order from top to bottom. Some reflective material particles may carry static charges during movement, and the filter body 1 may also carry opposite charges due to friction or other reasons. In this case, electrostatic adsorption will occur between the particles and the filter body 1, making it easier for the particles to adhere to the filter body 1, especially at the filter hole 2, where particles constantly pass through and are very likely to carry charges. In this embodiment, the conical setting of the filter hole 2 reduces the contact area between the filter hole 2 and the particles, thereby reducing the generation of charges at the filter hole 2, making it difficult for the filter hole 2 to adsorb particles, thereby ensuring the smooth flow of the filter hole 2.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
