Description

Technical Field

[0001] This utility model belongs to the field of screening-related technology, and in particular relates to a fixed structure for a linear screen mesh. Background Technology

[0002] Linear screens are common screening equipment widely used in various industries. They are typically driven by dual vibrating motors. When the two motors operate synchronously and in opposite directions, the excitation forces generated by their eccentric blocks cancel each other out in the direction parallel to the motor axes, and combine into a resultant force in the direction perpendicular to the motor axes. The two motor shafts are at an angle relative to the screen surface. Under the combined action of the excitation force and the material's own weight, the material is thrown up on the screen surface and moves forward in a straight line in a jumping motion, thus achieving the purpose of screening and grading the material. The most important part of a linear screen is the screen mesh. The material is thrown up and falls on the screen mesh, passing through it for screening. However, the following drawbacks still exist in the installation and fixing of the screen mesh: Screens are usually fixed to the screen frame with fasteners such as bolts. However, with long-term use, the screen will deform under stress, causing indentations, which reduces its screening efficiency and makes it difficult to maintain a tight state, making it easy to loosen. Secondly, once the screen is fixed, its tension cannot be changed. It cannot continue to tighten and maintain a taut state under conditions that may loosen. Therefore, once the screen loosens, it needs to be replaced, and the tension cannot be adjusted. Finally, the position of the screen is usually determined by only a few fastening points. After the screen is fixed, its position may shift due to subsequent operations. Utility Model Content

[0003] The purpose of this utility model is to provide a linear screen fixing structure. By setting up a pull plate assembly, clamping strip, bolts, screen frame, and screen shell, it solves the problems of conventional screen fixing methods that are easily deformed and dented under force, resulting in loosening and inability to maintain a tight state, the inability to adjust the tightness of the screen after fixing, and the possibility of the screen position shifting due to screening.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a linear screen fixing structure, including a screen shell, a screen frame, a pull plate assembly, clamping bars and bolts. The screen shell includes two vertical plates. The screen frame is distributed between the two vertical plates. The screen body is arranged above the screen frame. The two sides of the screen body are respectively placed in the two clamping bars. The clamping bar has a cross-section in the shape of ">", and the lower part of the clamping bar is horizontally arranged. A pull plate assembly is arranged above the clamping bar. The pull plate assembly includes an inclined mounting part, and an inclined abutment part is fixed to the higher end of the mounting part. A bending part is fixed to the lower end of the mounting part, and a tensioning part is fixed to the lower end of the bending part. The tensioning part extends into the inner angle of the clamping bar and abuts against the clamping bar as it moves toward the upright plate. The mounting portions of the pull plate assembly are all inclined and inserted with equally spaced bolts.

[0005] Furthermore, connecting rods are fixed between the corners of the opposite surfaces of the two vertical plates, and L-shaped support blocks are fixed on the opposite surfaces of the two vertical plates. The support blocks on the two vertical plates are symmetrically arranged. The bottom of the screen frame is fixed above the horizontal part of all the support blocks, and the side of the screen frame does not contact the vertical plates.

[0006] Furthermore, a convex limiting block is fixed to the bottom of the clamping bar, and the upper ends of the two long arms of the screen frame are provided with limiting grooves of the same number and size as the limiting blocks, and the limiting blocks below the clamping bar are slidably inserted into the limiting grooves below them.

[0007] Furthermore, the clamping bar has an internal receiving groove, and one end of the horizontal part of the clamping bar is open and connected to the receiving groove. Both sides of the screen body extend into the receiving groove, and the screen body is welded and fixed to the side of the clamping bar outside the opening of the clamping bar to form a weld.

[0008] Furthermore, the upright plate has equidistantly distributed oblique holes, and a base plate is fixed to the outer side of the upright plate outside the oblique holes, and a triangular block is fixed to the side of the base plate away from the upright plate.

[0009] Furthermore, the bolt passes through the mounting part and then sequentially through the inclined hole, the base plate, and the triangular block, and is screwed with a washer and a nut, with the washer tightly attached to the lower inclined surface of the triangular block.

[0010] Furthermore, the higher end of the abutting part abuts against the inner wall of the upright plate, and the pull plate assembly is located above the support block; the abutting part has an angle of 10° with the horizontal plane, and the mounting part has an angle of 45° with the horizontal plane.

[0011] This utility model has the following beneficial effects: This invention solves the problem that conventional screen fixing methods are prone to deformation and denting under stress, resulting in loosening and an inability to maintain a tight state. By setting up a pull plate assembly, clamping strips, bolts, and a screen shell, this invention changes the conventional fixing method by placing both sides of the screen body inside the clamping strips and fixing them. Then, the tensioning part of the pull plate assembly is inserted into the inner angle of the clamping strips, and the abutting part is abutted against the inner wall of the upright plate. At this time, the bolts are rotated so that the bolts and nuts lock together and move the bolts towards the upright plate. During this process, the tensioning part exerts a downward pulling force on the clamping strips, thereby making the screen body firmly taut. Because the entire side of the screen body is taut, there will be no problem of local deformation and denting after long-term use.

[0012] This invention solves the problem of the inability to adjust the tension of the screen after it is fixed by setting bolts, a pull plate assembly, and a clamping bar. Even after long-term use, if the screen body itself is slightly concave and not as tight as it was initially, the bolts can be rotated to further tighten it, causing the tensioning part to push the clamping bar and the side of the screen body towards the upright plate for further tensioning, keeping it tight and not loose. The tension can be adjusted according to actual needs.

[0013] This invention solves the problem of screen position shifting during screening by setting up a screen frame, clamping bars, and a pull plate assembly. A limiting groove is set at the upper end of the screen frame, and a limiting block is set at the bottom of the clamping bar. Before installing the screen, the limiting block at the bottom of the clamping bar is slidably set in the limiting groove. Under the pull of the subsequent pull plate assembly, the clamping bar and the screen are pulled taut towards the vertical plate. With the movable limiting of the limiting block, there will be no position shift during subsequent screening operations. The two sides of the screen enter the clamping bar and are then welded and fixed. This changes the bolt-type fixing method, resulting in a larger fixing area and preventing local shifting.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-8 As shown, this utility model is a linear screen fixing structure, including a screen shell 1, a screen frame 2, a pull plate assembly 3, clamping bars 4 and bolts 5. The screen shell 1 includes two vertical plates 101; the screen frame 2 is distributed between the two vertical plates 101, and the screen body 201 is arranged above the screen frame 2. The two sides of the screen body 201 are respectively placed in the two clamping bars 4. The screen shell 1 consists of two vertical plates 101 as the main body. The vertical plates 101 are connected by connecting rods 102 to form a frame structure. The screen frame 2 is installed between the two vertical plates 101. The screen body 201 is distributed above the screen frame 2, and the two sides of the screen body 201 are placed in two clamping strips 4 and welded and fixed. The clamping bar 4 has a cross-section in the shape of ">", and the lower part of the clamping bar 4 is set horizontally. A pull plate assembly 3 is set above the clamping bar 4. The clamping strip 4 with the ">" shaped structure is convenient for fixing the screen body 201. Then, it is used in conjunction with the pull plate assembly 3 to tighten the clamping strip 4, so that the screen body 201 is taut. The pull plate assembly 3 includes an inclined mounting part 301, and an inclined abutment part 302 is fixed to the higher end of the mounting part 301. A bending part 303 is fixed to the lower end of the mounting part 301. A tensioning part 304 is fixed to the lower end of the bending part 303.

The mounting parts 301 in the pull plate assembly 3 are all inclined and inserted with equally spaced bolts 5; The pull plate assembly 3, which is used as the main component for tightening the screen, no longer uses the traditional bolt 5 for fixing. In the pull plate assembly 3, the abutment part 302, the mounting part 301, the bending part 303 and the tensioning part 304 are integrally formed. The tensioning part 304 abuts against the inner angle of the clamping bar 4.

[0019] The bottom of the clamping bar 4 is fixed with a convex limiting block 403. The upper ends of the two long arms of the screen frame 2 are provided with limiting grooves 202 that are equal in number and size to the limiting blocks 403. The limiting blocks 403 below the clamping bar 4 are slidably inserted into the limiting grooves 202 below them. Before installing the screen body 201, the limiting block 403 at the bottom of the clamping bar 4 is slidably placed in the limiting groove 202. Under the pull of the subsequent pulling plate assembly 3, the clamping bar 4 and the screen body 201 are pulled tightly towards the vertical plate 101. With the movement of the limiting block 403, the position of the screen body 201 is kept stable.

[0020] The clamping bar 4 has an internal receiving groove 401, and one end of the horizontal part of the clamping bar 4 is open and connected to the receiving groove 401. Both sides of the screen body 201 extend into the receiving groove 401, and the screen body 201 is welded and fixed to the side of the clamping bar 4 outside the opening to form a weld 402. Insert the side of the screen body 201 into the receiving groove 401, and weld the clamping strip 4 outside the receiving groove 401 to the screen body 201 to form a weld 402, thus completing the welding and fixing, and fixing the entire side of the screen body 201.

[0021] An oblique hole 105 is provided in the upright plate 101 at equal intervals. A base plate 104 is fixed on the outside of the upright plate 101 outside the oblique hole 105, and a triangular block 1041 is fixed on the side of the base plate 104 away from the upright plate 101. Bolt 5 passes through mounting part 301 and then passes through inclined hole 105, base plate 104, triangular block 1041 in sequence, and is screwed with washer 501 and nut 502, with washer 501 in close contact with the lower inclined surface of triangular block 1041. The oblique hole 105 is set, the auxiliary bolt 5 extends obliquely, and after the bolt 5 extends out of the oblique hole 105, it extends out of the base plate 104 and the triangular block 1041. A washer 501 is fitted on the part of the bolt 5 that extends out of the triangular block 1041, and then the nut 502 is screwed on to lock it.

A connecting rod 102 is installed between the vertical plates 101 to form a frame structure. Then, a support block 103 is installed on the vertical plates 101, and the screen frame 2 is installed using the support block 103. Subsequently, the screen body 201 is installed, and the side of the screen body 201 is inserted into the receiving groove 401. A weld 402 is formed at the connection between the clamping strip 4 outside the receiving groove 401 and the screen body 201 to complete the welding and fixing. Then, the limiting block 403 at the bottom of the clamping strip 4 is slidably set in the limiting groove 202. Inside, the tensioning part 304 in the pull plate assembly 3 is inserted into the inner angle of the clamping bar 4, and then the abutting part 302 is abutted against the inner wall of the upright plate 101. At this time, the bolt 5 in the mounting part 301 is rotated. After the bolt 5 extends out of the inclined hole 105, it extends out of the base plate 104 and the triangular block 1041. A washer 501 is fitted on the part of the bolt 5 that extends out of the triangular block 1041, and then the nut 502 is screwed on to lock it. The bolt 5 is rotated to move towards the upright plate 101. During this process, the tensioning part 304 gives the clamping bar 4 a downward pulling force, so that the screen body 201 is firmly tightened.
