Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rigid-flexible coupling screen plate technology, and specifically relates to a rigid-flexible coupling screen plate. Background Technology
[0002] Screen plates are a type of screening device with interwoven mesh openings. They are mainly used to screen and separate materials according to their size. Screen plates can be divided into two categories based on their rigidity and strength: rigid screen plates and flexible screen plates. Rigid-flexible coupling screen plates are a type of screen plate that combines the characteristics of both rigid and flexible screen plates.
[0003] For example, Chinese utility model patent CN221966050U discloses a modular rigid-flexible screen, and Chinese utility model patent CN220941834U discloses a polyurethane rigid-flexible screen. In the prior art, rigid-flexible coupling screen plates mainly adopt the method of assembling flexible screen plates on screen plate frames to couple rigid screen plates with flexible screen plates. Although this method can couple rigid screen plates with flexible screen plates, the rigid-flexible coupling screen plates formed by the combination have poor flexibility, resulting in poor actual application effect of rigid-flexible coupling screen plates.
[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a rigid-flexible coupling screen plate.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this invention is to provide a rigid-flexible coupling screen plate that can improve the flexibility of the rigid-flexible coupling screen plate.
[0007] To achieve the above objectives, a specific embodiment of this utility model provides a rigid-flexible coupling screen plate, comprising multiple sets of rigid screen plates, with flexible screen plates assembled between each set of rigid screen plates. Each set of flexible screen plates has an integrally formed insertion positioning plate on both sides. Positioning grooves are provided on both sides of each set of rigid screen plates. The insertion positioning plates are inserted into the positioning grooves. A positioning block is slidably assembled on one side of each insertion positioning plate located within the positioning groove. Multiple assembly bolts are threadedly connected between the rigid screen plates and the insertion positioning plates.
[0008] In one or more embodiments of this utility model, the rigid screen plate is composed of two parts: a rigid screen surface and a rigid screen frame. The rigid screen frame is fixedly fitted on the outside of the rigid screen surface, and the positioning groove is opened on the side of the rigid screen frame away from the rigid screen surface.
[0009] In one or more embodiments of this utility model, the flexible screen plate is composed of two parts: a flexible screen surface and a flexible screen frame. The flexible screen frame is fixedly fitted on the outside of the flexible screen surface, and the plug-in positioning plate is fixedly connected to the side of the flexible screen frame close to the rigid screen frame.
[0010] In one or more embodiments of this utility model, a positioning through hole is provided on the side of the positioning groove opposite to the rigid screen surface, and the positioning block is slidably assembled in the positioning through hole. The cooperation between the positioning block and the positioning through hole plays a role in the insertion and positioning of the insertion positioning plate and the positioning groove.
[0011] In one or more embodiments of this utility model, a pair of shrinkage limiting pads are fixedly connected to one side of the insertion positioning plate located in the positioning groove, and the pair of shrinkage limiting pads are symmetrically arranged on both sides of the positioning block. By setting a pair of shrinkage limiting pads, the insertion and fitting gap between the insertion positioning plate and the positioning groove is reduced, ensuring the stability of the insertion and assembly of the insertion positioning plate and the positioning groove.
[0012] In one or more embodiments of this utility model, a shrink-limiting box is fixedly assembled inside the insertion positioning plate, and the positioning block is slidably assembled inside the shrink-limiting box. The side of the shrink-limiting box outside the insertion positioning plate is at the same level as the bottom surface of the insertion positioning plate. The shrink-limiting box serves to store and limit the movement of the positioning block, reducing the interference between the shrink-limiting box and the positioning groove during the insertion process of the insertion positioning plate.
[0013] In one or more embodiments of this utility model, the side of the positioning block outside the shrinkage limiting box is chamfered. By chamfering the side of the positioning block outside the shrinkage limiting box, the smoothness of the insertion and positioning of the positioning block and the positioning through hole is improved.
[0014] In one or more embodiments of this utility model, an inner partition is fixedly connected to one end of the positioning block located inside the shrinkage limiting box, and the inner partition is slidably assembled inside the shrinkage limiting box. The positioning block is supported and limited by moving and limiting the inner partition.
[0015] In one or more embodiments of this utility model, multiple sets of evenly distributed return springs are arranged between the inner partition and the retraction limiting box. The retraction and retraction of the return springs provide support and limitation for the inner partition.
[0016] Compared with the prior art, the rigid-flexible coupling screen plate disclosed in this utility model adopts an integral combination method to assemble a flexible screen plate and a rigid screen plate, which improves the overall flexibility of the rigid-flexible coupling screen plate, making it suitable for different environments and improving the practical application effect of the rigid-flexible coupling screen plate.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0026] like Figures 1 to 5 As shown, a rigid-flexible coupling screen plate in one embodiment of the present invention includes multiple sets of rigid screen plates 1.
[0027] like Figures 1 to 2As shown, the rigid screen plate 1 consists of two parts: a rigid screen surface 101 and a rigid screen frame 102. The rigid screen frame 102 is fixedly fitted onto the outside of the rigid screen surface 101, and the positioning groove 4 is opened on the side of the rigid screen frame 102 opposite to the rigid screen surface 101. The rigid screen surface 101 is assembled and fixed by the rigid screen frame 102, and the material to be screened is screened and separated by the rigid screen surface 101.
[0028] like Figures 1 to 2 As shown, flexible screen plates 2 are assembled between multiple sets of rigid screen plates 1. The coupling of multiple sets of flexible screen plates 2 with rigid screen plates 1 combines the screen plate characteristics of rigid screen plates 1 and flexible screen plates 2, thereby improving the overall flexibility of the screen plates.
[0029] like Figures 1 to 2 As shown, the flexible screen plate 2 consists of two parts: a flexible screen surface 201 and a flexible screen frame 202. The flexible screen frame 202 is fixedly fitted onto the outside of the flexible screen surface 201. The flexible screen surface 201 separates and screens the material to be screened. At the same time, the flexible screen plate 2 and the rigid screen plate 1 can be assembled and combined by assembling and fixing the flexible screen frame 202.
[0030] like Figures 1 to 4 As shown, the plug-in positioning plate 3 is fixedly connected to the side of the flexible screen frame 202 that is close to the rigid screen frame 102. The flexible screen plate 2 and the rigid screen plate 1 are combined and fixed by assembling and fixing the plug-in positioning plate 3.
[0031] like Figures 1 to 4 As shown, each of the multiple sets of flexible screen plates 2 has an integrally formed insertion positioning plate 3 on both sides. The flexible screen plate 2 and the rigid screen plate 1 are coupled and assembled by assembling and fixing the insertion positioning plate 3.
[0032] like Figure 4 As shown, positioning grooves 4 are provided on both sides of multiple sets of rigid screen plates 1, and multiple sets of plug-in positioning plates 3 are inserted and assembled in the positioning grooves 4. By inserting and assembling the plug-in positioning plates 3 in the positioning grooves 4, the flexible screen plate 2 and the rigid screen plate 1 can be combined and positioned.
[0033] like Figures 2 to 3 As shown, a pair of shrinkage limiting pads 7 are fixedly connected to one side of the insertion positioning plate 3 located in the positioning groove 4. The pair of shrinkage limiting pads 7 are symmetrically arranged on both sides of the positioning block 5. By setting a pair of shrinkage limiting pads 7, the insertion gap between the insertion positioning plate 3 and the positioning groove 4 is reduced, ensuring the stability of the insertion assembly of the insertion positioning plate 3 and the positioning groove 4.
[0034] Specifically, the horizontal height of the flexible screen surface 201 and the rigid screen surface 101 can be adjusted by replacing the shrinkage limiting pads 7 of different thicknesses.
[0035] The positioning groove 4 has a positioning through hole on the side opposite to the rigid screen surface 101, and the positioning block 5 is slidably assembled in the positioning through hole. The positioning block 5 and the positioning through hole cooperate to achieve the insertion and positioning of the insertion positioning plate 3 and the positioning groove 4.
[0036] like Figures 2 to 5 As shown, multiple sets of insertion positioning plates 3 are slidably fitted with positioning blocks 5 on one side of the positioning groove 4. The insertion positioning plates 3 are inserted and positioned by the cooperation between the positioning blocks 5 and the positioning through holes.
[0037] like Figures 2 to 5 As shown, multiple assembly bolts 6 are threadedly connected between the rigid screen plate 1 and the plug-in positioning plate 3. The multiple assembly bolts 6 are used to assemble and fix the plug-in positioning plate 3 and the rigid screen plate 1, ensuring the connection stability between the flexible screen plate 2 and the rigid screen plate 1.
[0038] like Figures 2 to 5 As shown, a shrink-limiting box 8 is fixedly installed inside the insertion positioning plate 3, and the positioning block 5 is slidably installed inside the shrink-limiting box 8. The side of the shrink-limiting box 8 located outside the insertion positioning plate 3 is at the same level as the bottom surface of the insertion positioning plate 3. The shrink-limiting box 8 serves to store and limit the movement of the positioning block 5, reducing the interference between the shrink-limiting box 8 and the positioning groove 4 during the insertion process of the insertion positioning plate 3.
[0039] Specifically, the side of the positioning block 5 located outside the shrinkage limiting box 8 is chamfered. By chamfering the side of the positioning block 5 located outside the shrinkage limiting box 8, the smoothness of the insertion and positioning of the positioning block 5 and the positioning through hole is improved.
[0040] like Figures 2 to 5 As shown, one end of the positioning block 5 located inside the shrinkage limiting box 8 is fixedly connected to an inner partition 9, which is slidably assembled inside the shrinkage limiting box 8. The positioning block 5 is supported and limited by moving and limiting the inner partition 9.
[0041] like Figures 2 to 5 As shown, multiple sets of evenly distributed return springs 10 are arranged between the inner partition 9 and the retraction limiting box 8. The retraction and retraction of the return springs 10 provide support and limit for the inner partition 9.
[0042] In practical use, the flexible screen plate 2 and the rigid screen plate 1 can be initially connected by inserting and assembling the insertion positioning plate 3 into the positioning groove 4. During the insertion and assembly of the insertion positioning plate 3, the insertion positioning plate 3 can be assisted in positioning by the cooperation of the positioning block 5 and the positioning through hole.
[0043] Meanwhile, the insertion gap between the insertion positioning plate 3 and the positioning groove 4 can be filled by setting a shrinkage limiting pad 7 between the insertion positioning plate 3 and the positioning groove 4, which ensures the insertion stability of the insertion positioning plate 3 and the positioning groove 4. After the insertion is completed, the flexible screen plate 2 and the rigid screen plate 1 can be combined and fixed by threading the insertion positioning plate 3 and the rigid screen plate 1 with multiple sets of assembly bolts 6. The overall flexibility of the rigid-flexible coupling screen plate is improved by the integral coupling of the flexible screen plate 2 and the rigid screen plate 1.
