TECHNICAL FIELD
[0001] The utility model belongs to the vibrating screen sieve plate equipment technical field, concretely relates to a vibrating screen inner material receiving switching line device. BACKGROUND
[0002] In the material screening process, the vibrating screen is an important equipment, and the performance of the vibrating screen directly affects the screening efficiency and the product quality. The vibrating screen widely used in the current market adopts the design that the screen hole gradually expands outward from the surface to the back. This design helps to prevent the hole blocking phenomenon and improve the material passing efficiency. However, its disadvantage is also obvious. Due to the continuous wear of the screen hole edge, the effective area of the screen hole will gradually decrease with the increase of the use time, resulting in the decline of the screening quality.
[0003] In comparison, the linear screen hole (vertical surface) performs relatively well in the wear process, because its wear is mainly concentrated in the linear edge of the screen hole, prolonging the service life of the screen hole. However, the traditional vibrating screen adopts the fixed screen hole design. When the hole diameter is worn to a certain extent, the operator is forced to frequently replace the sieve plate, increasing the production cost and maintenance difficulty. This high-frequency replacement not only occupies a large amount of human and material resources, but also may cause shutdown and loss in the production process. In addition, the sieve plate of the prior art cannot be adjusted as needed, which is not very convenient to use.
[0004] Therefore, there is an urgent need for a new design in the market to effectively solve the problems faced by the traditional vibrating screen in the screen hole wear process. Therefore, a vibrating screen inner material receiving switching line device is proposed. CONTENT OF THE UTILITY MODEL

[0019] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the following will be briefly introduced to the drawings needed to be used in the embodiment description, and obviously, the drawings in the following description are some embodiments of the utility model, and for the ordinary skilled in the art, other drawings can also be obtained according to these drawings without the creative labor.
[0020] In the following description, many specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the utility model is not limited to the specific embodiments disclosed in the following disclosure.
[0021] Embodiment 1, as Figure 1As shown, a vibrating screen inner material switching line device includes a main screen plate 1 provided with screen holes 2, the main screen plate 1 is the main load-bearing component of the vibrating screen, used to support and contain the material to be screened. The structure and material of the screen plate have sufficient strength and toughness to withstand the impact and vibration of the material. The screen plate is made of durable material, reducing the frequency of replacement and thus reducing maintenance costs. The screen holes 2 are used for screening the material, and the shape and size of the screen holes 2 determine the accuracy and efficiency of the screening.
[0022] The main screen plate 1 is provided with extension plates 3 on both sides, which are used to carry and support other components. The extension plates 3 are provided with sliding grooves 4 at the top, and the extension plates 3 are provided with adjusting plates 5. The adjusting plates 5 can move in the sliding grooves 4 to change the size of the screen holes 2, adapting to the needs of different materials and production. Through the flexible movement function of the adjusting plates 5, the size of the screen holes 2 can be quickly adjusted, widening the application range of the screening products, and prolonging the service life of the screen plate. The sliding grooves 4 are used to carry the adjusting plates 5 and allow the adjusting plates 5 to slide within a certain range to achieve the adjustment of the screen holes 2. The adjusting plates 5 are provided with adjusting holes 6, which control the size and shape of the screen holes 2 through the movement of the adjusting plates 5, directly affecting the screening effect. The adjusting plates 5 are provided with fastening bolts 7 at the top of the two side edges, which are used to fix the adjusting plates 5.
[0023] Now let's talk about the specific design of the above key components:
[0024] The screen holes 2 are in the shape of a water droplet, and the screen holes 2 are arranged in a square array on the main screen plate 1. The edges of the water droplet shape can effectively reduce the accumulation of material in the screen holes 2, reducing the risk of blockage. At the same time, the geometric characteristics of the water droplet shape can provide better screening effect to some extent, enhancing the flowability of the material. The square array design makes the screen holes 2 evenly distributed, which can maximize the use of the area of the screen plate, improving the overall efficiency of the screening.
[0025] The adjusting holes 6 are in the shape of a long strip, the length of the adjusting holes 6 is the same as the width of the main screen plate 1, and the length of the adjusting holes 6 is half the length of the screen holes 2. The design of the long strip shape makes the adjusting holes 6 flexible in changing the size of the screen holes 2 when the adjusting plate 5 moves, adapting to different types and particle sizes of materials, thereby improving the adaptability and flexibility of the screening. Due to the design of the adjusting holes 6, the operator can conveniently adjust the open area of the screen holes 2 to meet various production needs, which can reduce the production downtime caused by frequent replacement of screen plates.
[0026] The bottom edges of the adjusting plate 5 are provided with sliding blocks arranged in the sliding grooves 4. The design of the sliding blocks allows the adjusting plate 5 to move smoothly in the sliding grooves 4, thereby facilitating the adjustment of the size of the screen holes 2. The cooperation between the sliding blocks and the sliding grooves 4 ensures the smoothness of the sliding and reduces the friction and abrasion during operation. The width and height of the sliding blocks are designed to match the size of the sliding grooves 4, so as to ensure the stability and smoothness of the adjusting plate 5 during operation.
[0027] The side walls of the extension plate 3 are provided with insertion grooves, and the main screen plate 1 is inserted into the insertion grooves. The main screen plate 1 can be stably inserted into the extension plate 3, which facilitates the installation and disassembly of the extension plate 3, and can conveniently replace, adjust or clean the extension plate 3, thereby improving the maintenance convenience.
[0028] The thickness of the adjusting plate 5 is 5-10 mm, and the material of the sliding block is polyoxymethylene. The appropriate thickness of the adjusting plate 5 is not easy to deform when subjected to stress, and at the same time can meet the requirements of friction and rigidity, so as to ensure that the adjustment can be stably and reliably carried out during the screening process. The material of the sliding block is polyoxymethylene (POM), which is suitable for the manufacture of sliding parts due to its excellent wear resistance and low friction coefficient. The use of polyoxymethylene can effectively reduce the friction resistance during the adjustment process and improve the service life.
[0029] The fastening bolt 7 adopts a standard M8 model and is provided with a lock washer. After being slid to the appropriate position, the fastening bolt 7 presses the bottom of the sliding groove 4 to fix the adjusting plate 5, so as to ensure that the adjusting plate 5 can remain stable during the screening process and avoid loosening or displacement during vibration and operation.
[0030] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be ordered according to the description and the drawings. The specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art. The mechanical parts and equipment adopt conventional models in the prior art. The circuit connection adopts the conventional connection mode in the prior art, which will not be described in detail here. The contents not described in detail in the specification belong to the prior art known to those skilled in the art.
[0031] The above is only a preferred embodiment of the utility model, and is not a limitation on other forms of the utility model. Any skilled person in the art can modify or change the above disclosed technical content to apply to other fields as equivalent embodiments, but any simple modification, equivalent change and modification made on the basis of the technical essence of the utility model to the above embodiments shall fall within the protection scope of the technical scheme of the utility model.
