Description

Technical Field

[0001] The present application relates to the technical field of screening equipment, and in particular to an anti-clogging relaxation screen. Background Art

[0002] The flap screen is a type of vibrating screen, which is a device that uses the principle of vibration to screen and grade materials. The vibrating screen separates the materials on the screen surface by generating vibration. The elastic screen surface on the flap screen will perform a relaxation and tension movement on the inclined screen box, and the material will be thrown upward by the relaxation and tension movement of the elastic screen surface, which can reduce the blockage of the screen and can be applied to multiple industries.

[0003] For example, the Chinese patent document with the announcement number CN219129917U discloses a single-layer relaxation vibration screen, including a mounting frame, the mounting frame is used to provide an installation space, a disassembly mechanism is fixedly connected to the right side of the mounting frame, the disassembly mechanism is used to realize the rapid installation and disassembly of the screen surface, and a vibration mechanism is fixedly connected to the left side of the mounting frame, the vibration mechanism is used to provide power for the screen of the relaxation screen. When screening the material, the material is directly dropped from the upper end of the screen, and then the vibration mechanism drives the screen to vibrate. While the screen vibrates, the screen throws the material upward through relaxation and tension movements, thereby realizing the screening of the material and reducing the blockage of the screen.

[0004] In the above-mentioned related technologies, materials can be screened by the vibration and relaxation of the screen. However, when there are many small particles in the material, a part of the small particles above the screen will fall down together with the large particles, resulting in a part of small particles still in the large particles after screening. At this time, in order to improve the screening effect, it is necessary to reduce the speed at which the material falls onto the screen, so that the amount of material on the screen in the same time can be reduced, thereby improving the screening effect of the material. Since the falling speed of the material is reduced, the screening efficiency of the material will be reduced. Summary of the invention

[0005] The present application provides an anti-clogging relaxation screen, aiming to solve the problem of reduced material screening efficiency in the related art.

[0006] The anti-clogging loose-fitting screen provided in the present application adopts the following technical solution: A kind of anti-clogging loose screen, comprising a loose screen body and a screen arranged on the loose screen body, a mounting plate fixedly mounted on the loose screen body, the mounting plate being arranged above the screen, a mounting shell being arranged on the mounting plate, a plurality of groups of partition components being arranged on the mounting shell, the plurality of groups of partition components being arranged at intervals along the width direction of the screen, the plurality of groups of partition components dividing the area above the screen into a plurality of screening channels, an adjusting component for adjusting the position of the partition component being arranged on the mounting shell, the partition component comprising a plurality of first partition plates and a plurality of second partition plates, one end of the first partition plate and the second partition plate being hinged via a partition shaft, the plurality of first partition plates and the plurality of second partition plates being alternately arranged along the length direction of the screen; a moving rod being slidably connected to the mounting shell, the partition shafts on the plurality of groups of partition components are all rotatably connected to the moving rod, and when the moving rod moves, the angles of the plurality of groups of partition components are adjusted.

[0007] By adopting the above technical solution, in the initial state, the multiple first partition plates and the multiple second partition plates of each group of partition components are in the same straight line. At this time, the material falling on the screen takes the shortest path during screening; the adjustment component on the mounting shell can drive the moving rod to move along the length direction of the screen, and adjust the position of the moving rod. When the distance between two adjacent moving rods is the shortest, the adjacent first partition plates and the second partition plates are vertically arranged, so that the number of vertical positions of the first partition plates and the second partition plates can be adjusted by adjusting the number of movements of the moving rod. The more the number of vertical positions of the first partition plates and the second partition plates is, the longer the path of the material on the screen is, and then the screening effect of the material on the screen is better.

[0008] Optionally, the adjustment component includes a first adjusting roller, a second adjusting roller and a pushing roller rotating on the mounting shell, and an adjusting conveyor belt wound around the first adjusting roller and the second adjusting roller, the axes of the first adjusting roller and the second adjusting roller are staggered, a plurality of connecting blocks are fixedly mounted on the adjusting conveyor belt, and the movable rod is provided with a connecting groove for clamping the connecting block; a control component for driving the pushing roller to move along the length direction of the adjusting conveyor belt is provided on the mounting shell, and the control component is also used to push the connecting block on the adjusting conveyor belt to move into the connecting groove.

[0009] By adopting the above technical solution, when the connecting block moves into the connecting groove, the conveyor belt is adjusted to drive the connecting block to rotate, so that the connecting block drives the moving rod above the screen to move at the same time, and when the moving rod close to the second adjusting roller moves to the extreme position, the adjacent first partition plate and the second partition plate are vertically arranged, and then the push roller is driven by the control component to move in the direction close to the first adjusting roller. At this time, the moving rod and the connecting groove in the extreme position will be disengaged, and then in the subsequent movement of the moving rod, the moving rod in the extreme position will not be driven to move, thereby making it more convenient to adjust the length of the screening channel.

[0010] Optionally, the control component includes a control screw rotatably connected to the mounting shell, a control block slidably connected to the mounting shell, and a control motor fixed to the mounting shell, the control block slides along the length direction of the screen, the control screw is passed through the control block and threadedly connected to the control block, and the push roller is rotatably connected to the control block; a tensioning component for adjusting the conveyor belt to keep it taut is provided on the mounting shell.

[0011] By adopting the above technical solution, when the control screw rotates, the control block and the push roller rotatably connected to the control block are driven to move, thereby adjusting the length of the horizontal part and the inclined part on the conveyor belt.

[0012] Optionally, the tensioning assembly includes a tensioning plate slidably connected to the mounting shell, a tensioning roller rotatably connected to the tensioning plate, and a tensioning spring fixed to the tensioning plate, the tensioning roller is arranged between the first adjusting roller and the second adjusting roller, and the tensioning roller abuts against the inner side surface of the adjusting conveyor belt, and the end of the tensioning spring away from the tensioning plate is fixed to the mounting shell, and the tensioning spring is used to drive the tensioning plate and the tensioning roller to move in a direction away from the side of the screen.

[0013] By adopting the above technical solution, when the inclined portion becomes longer, the tensioning wheel pulls the adjusting conveyor belt to move away from the partition component under the action of the tensioning spring, and then in the process of pushing the roller to move, the adjusting conveyor belt can always remain in a tensioned state, thereby facilitating the connecting block to be better positioned in the connecting groove.

[0014] Optionally, a linkage assembly for adjusting the positions of the first adjusting roller and the second adjusting roller is provided on the mounting shell; the linkage assembly comprises a first linkage block, a second linkage block, a linkage shaft, a first linkage rod and a second linkage rod, the first adjusting roller is rotatably connected to the first linkage block, and the first linkage block is slidably connected to the mounting shell along the width direction of the screen, the second adjusting roller is rotatably connected to the second linkage block, and the second linkage block is slidably connected to the mounting shell along the width direction of the screen; the linkage shaft is fixedly mounted on the second linkage rod and rotatably connected to the mounting plate; two first linkage rods are provided, both of which are slidably connected to the second linkage rod along the length direction of the screen, and one end of one first linkage rod away from the second linkage rod is hinged to the first linkage block, and the other end of the other first linkage rod away from the second linkage rod is hinged to the second linkage block.

[0015] By adopting the above technical scheme, when it is necessary to reduce the vertical number of the first partition plate and the second partition plate on the screen, the linkage shaft is rotated to drive the second linkage rod to rotate. At this time, the two first linkage rods will drive the first linkage block and the second linkage block to move, thereby adjusting the position of the first adjusting roller and the second adjusting roller, so that the distance between the first adjusting roller and the side of the screen is smaller than the distance between the second adjusting roller and the side of the screen. At this time, the adjusting conveyor belt between the first adjusting roller and the pushing roller is the inclined part, and the adjusting conveyor belt between the second adjusting roller and the pushing roller is the horizontal part. In the process of the reverse movement of the adjusting conveyor belt, it is convenient to pull the moving rod on the screen to move in the direction close to the storage chamber, so that the first partition plate and the second partition plate on the screen can be in the same straight line.

[0016] Optionally, the partition assembly is provided with a scattering assembly for scattering the thrown materials, and the scattering assembly includes a scattering spring fixedly mounted on the first partition plate and a scattering plate fixed on the scattering spring.

[0017] By adopting the above technical solution, while the screen and the relaxation screen body vibrate, the free end of the scattering spring will drive the scattering plate to swing, and then scatter the thrown materials, thereby reducing the accumulation of fallen materials, thereby improving the screening efficiency of the materials.

[0018] Optionally, a breaking up component is provided on each of the first partition plates and the second partition plates.

[0019] By adopting the above technical solution, since a breaking component is provided on each of the first partition plate and the second partition plate, the material can be better broken up while the screen and the relaxation screen body are vibrating.

[0020] Optionally, a swinging assembly for driving the mounting shell to reciprocate is provided on the mounting plate, the swinging assembly includes a swinging plate rotatably connected to the mounting plate, a swinging rod hinged on the swinging plate, and a swinging motor fixed on the mounting plate, the output shaft of the swinging motor is fixed on the swinging plate, the end of the swinging rod away from the swinging plate is hinged on the mounting shell, and the swinging rod and the swinging plate are hinged at a non-center point.

[0021] By adopting the above technical solution, when the swing plate rotates, under the action of the swing rod, the mounting shell is driven to move back and forth along the width direction of the screen, so that the mounting shell drives the partition assembly to move back and forth, and then the partition assembly pushes the material to move back and forth, thereby improving the screening efficiency of the material.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The number of vertical movements of the first partition plate and the second partition plate can be adjusted by adjusting the number of movements of the moving rod. The more vertical movements of the first partition plate and the second partition plate, the longer the path of the material on the screen, and the better the screening effect of the material on the screen.

[0023] 2. While the screen and the relaxation screen body are vibrating, the free end of the scattering spring will drive the scattering plate to swing, and then scatter the thrown materials, thereby reducing the accumulation of fallen materials and improving the screening efficiency of the materials.

DETAILED DESCRIPTION

[0032] The following combination Figure 1-Figure 7 This application is described in further detail.

[0033] Embodiment 1: The present application discloses an anti-clogging loose-fitting screen. Figure 1 , Figure 2 and Figure 7 A clogging-proof flap screen comprises a flap screen body 01 and a screen 02 arranged on the flap screen body 01, a mounting plate 03 is fixedly mounted on the flap screen body 01, the mounting plate 03 is arranged above the screening net, and a mounting shell 04 is arranged between the mounting plate 03 and the screen 02, and the mounting shell 04 is arranged on the mounting plate 03; a plurality of groups of partition components 1 are arranged on the mounting shell 04, and the plurality of groups of partition components 1 are arranged at intervals along the width direction of the screen 02, and the plurality of groups of partition components 1 divide the upper part of the screen 02 into a plurality of screening channels 05, and an adjusting component 2 is arranged on the mounting shell 04 at the same time, and the adjusting component 2 is used to adjust the position of the partition component 1, so as to change the length of each screening channel 05, thereby increasing the time that the material stays on the screen 02, and making the material screening effect better under the condition of the same material feeding speed. In addition, a feed hopper 06 is provided on the mounting shell 04. The material is transported to the feed hopper 06 through a conveyor belt, and then falls onto the screen 02 through the feed hopper 06. At this time, the screen 02 is driven to vibrate through the relaxation screen body 01 to screen the material.

[0034] Reference Figures 1 to 3 The partition assembly 1 includes multiple first partition plates 11 and multiple second partition plates 12, one end of the first partition plate 11 and the second partition plate 12 are hinged by a partition axis, and the multiple first partition plates 11 and the multiple second partition plates 12 are alternately arranged along the length direction of the screen 02; at the same time, a moving rod 13 is slidably connected to the mounting shell 04, and the partition axes on the multiple groups of partition assemblies 1 are all rotatably connected to the moving rod 13, and the moving rod 13 is slidably connected to the mounting shell 04 along the length direction of the screen 02. When the moving rod 13 moves, the angles of the multiple groups of partition assemblies 1 can be adjusted at the same time; a first partition plate 11 and a second partition plate 12 are arranged between the two moving rods 13, and the angle of the first partition plate 11 and the second partition plate 12 between two adjacent moving rods 13 can be adjusted by sliding the moving rod 13 on the mounting shell 04.

[0035] In the initial state, the multiple first partition plates 11 and the multiple second partition plates 12 of each group of partition components 1 are in the same straight line. At this time, the material falling on the screen 02 takes the shortest path during screening; the adjustment component 2 on the mounting shell 04 can drive the moving rod 13 to move along the length direction of the screen 02, and adjust the position of the moving rod 13. When the distance between two adjacent moving rods 13 is closest, the adjacent first partition plates 11 and the second partition plates 12 are vertically arranged, so that the number of vertical positions of the first partition plates 11 and the second partition plates 12 can be adjusted by adjusting the number of movements of the moving rod 13. The more the number of vertical positions of the first partition plates 11 and the second partition plates 12 is, the longer the path of the material on the screen 02 is, and then the screening effect of the material on the screen 02 is better.

[0036] When the first partition plate 11 and the second partition plate 12 on the screen 02 are all arranged vertically, the path of the material on the screen 02 is the longest; at the same time, a storage chamber 3 is arranged on the mounting shell 04, and when the first partition plate 11 and the second partition plate 12 on the screen 02 are in the same straight line, the length of the straightened partition assembly 1 is greater than the length of the screen 02, and at this time, the first partition plate 11 and the second partition plate 12 that are longer than the length of the screen 02 are in the storage chamber 3; when the first partition plate 11 and the second partition plate 12 on the screen 02 need to be arranged vertically, the first partition plate 11 and the second partition plate 12 in the storage chamber 3 will be moved out; in addition, in order to reduce the length of the storage chamber 3, the first partition plate 11 and the second partition plate 12 in the storage chamber 3 are arranged at an angle.

[0037] Reference Figures 2 to 5 The adjusting assembly 2 includes a first adjusting roller 21, a second adjusting roller 22 and a pushing roller 23 rotating on the mounting shell 04, and an adjusting conveyor belt 24 wound around the first adjusting roller 21 and the second adjusting roller 22. An adjusting motor is arranged on the mounting shell 04, the adjusting motor is connected to the first adjusting roller 21, and is used to drive the first adjusting roller 21 to rotate. In this embodiment, the axes of the first adjusting roller 21 and the second adjusting roller 22 are staggered; a plurality of connecting blocks 31 are fixedly mounted on the adjusting conveyor belt 24, and a connecting groove 32 is provided on the moving rod 13, and the opening of the connecting groove 32 is opened toward the direction of the adjusting conveyor belt 24; in addition, a control assembly 6 is arranged on the mounting shell 04, the control assembly 6 is used to drive the pushing roller 23 to move along the length direction of the adjusting conveyor belt 24, and is used to push the connecting block 31 on the adjusting conveyor belt 24 to move into the connecting groove 32, so that the moving rod 13 can be driven to slide on the mounting shell 04 by the adjusting conveyor belt 24, thereby facilitating the adjustment of the position of the moving rod 13. Under the action of the pushing roller 23 , the adjusting conveyor belt 24 is divided into a horizontal portion 241 and an inclined portion 242 , the connecting block 31 of the horizontal portion 241 is in the connecting groove 32 , and the connecting block 31 of the inclined portion 242 is separated from the connecting groove 32 .

[0038] When the path of the screening channel 05 needs to be lengthened, the first partition plate 11 and the second partition plate 12 above the screen 02 need to be arranged vertically. At this time, the straight-line distance between the first adjusting roller 21 and the side of the screen 02 is smaller than the straight-line distance between the second adjusting roller 22 and the side of the screen 02. Then the adjusting conveyor belt 24 between the first adjusting roller 21 and the pushing roller 23 is the horizontal portion 241, and the adjusting conveyor belt 24 between the second adjusting roller 22 and the pushing roller 23 is the inclined portion 242. When the path of the screening channel 05 needs to be shortened, the distance between the axis of the first adjusting roller 21 and the screening side is smaller than the distance between the axis of the second adjusting roller 22 and the side of the screen 02, the adjusting conveyor belt 24 between the first adjusting roller 21 and the pushing roller 23 is an inclined portion 242, and the adjusting conveyor belt 24 between the second adjusting roller 22 and the pushing roller 23 is an inclined portion 242, and then the connecting block 31 is pushed by the pushing roller 23 to move into the connecting groove 32, thereby straightening the first partition plate 11 and the second partition plate 12 vertically above the screen 02, and then the partition assembly 1 that needs to be straightened is transported to the storage chamber 3.

[0039] Reference Figures 2 to 5 In order to facilitate the adjustment of the positions of the first adjusting roller 21 and the second adjusting roller 22, a linkage component 4 is provided on the mounting shell 04; while the push roller 23 moves, in order to keep the adjusting conveyor belt 24 always in a taut state, a tensioning component 5 for keeping the adjusting conveyor belt 24 taut is provided on the mounting shell 04.

[0040] Reference Figures 2 to 5 The control assembly 6 includes a control screw 61 rotatably connected to the mounting shell 04, a control block 62 slidably connected to the mounting shell 04, and a control motor fixed to the mounting shell 04. The control block 62 slides along the length direction of the screen 02. The output shaft of the control motor is connected to the control screw 61. The control screw 61 is driven to rotate by the control motor. The control screw 61 is penetrated by the control block 62 and is threadedly connected to the control block 62. The push roller 23 is rotatably connected to the control block 62. When the control screw 61 rotates, it drives the control block 62 and the push roller 23 rotatably connected to the control block 62 to move, thereby adjusting the length of the horizontal portion 241 and the inclined portion 242 on the conveyor belt 24.

[0041] In the initial state, the first partition plate 11 and the second partition plate 12 above the screen 02 are in the same straight line. At this time, the moving rods 13 above the screen 02 are connected by the connecting block 31 and the adjusting conveyor belt 24. The distance between the axis of the push roller 23 and the axis of the second adjusting roller 22 is the smallest, and the inclined portion 242 is also the shortest. Then, when it is necessary to adjust the number of vertically arranged first partition plates 11 and second partition plates 12 above the screen 02, the adjusting conveyor belt 24 drives the connecting block 31 and the moving rod 13 to move, and at the same time, the push roller 23 moves in the direction away from the first adjusting roller 21. When multiple moving rods 13 move, the moving rod 13 close to the second adjusting roller 22 moves to the limit position first. At this time, the corresponding first partition plates 11 and second partition plates 12 are vertically arranged and move to The moving rod 13 at the extreme position cannot move further, and the push roller 23 moves in the direction away from the second adjusting roller 22. The length of the inclined portion 242 between the push roller 23 and the second adjusting roller 22 gradually increases. At this time, the connecting block 31 on the inclined portion 242 is separated from the connecting groove 32 close to the second adjusting roller 22. As the length of the inclined portion 242 gradually increases, the number of moving rods 13 connected to the adjusting conveyor belt 24 will also decrease, and then the adjacent moving rods 13 will continue to move in the process of the adjusting conveyor belt 24 continuing to move. By analogy, the number of vertical first partition plates 11 and second partition plates 12 on the screen 02 is adjusted as needed. The more vertical first partition plates 11 and second partition plates 12 are, the longer the path of the screening channel 05 is, and the material screening is more thorough. In this embodiment, the number of vertical first partition plates 11 and second partition plates 12 above the screen 02 is set according to the proportion of large and small particles in the material.

[0042] When it is necessary to reduce the vertical number of the first partition plate 11 and the second partition plate 12 on the screen 02, the position of the first adjusting roller 21 and the second adjusting roller 22 is adjusted by the linkage assembly 4, so that the distance between the first adjusting roller 21 and the side of the screen 02 is less than the distance between the second adjusting roller 22 and the side of the screen 02. At this time, the adjusting conveyor belt 24 between the first adjusting roller 21 and the push roller 23 is an inclined portion 242, and the adjusting conveyor belt 24 between the second adjusting roller 22 and the push roller 23 is a horizontal portion 241. In the process of the adjusting conveyor belt 24 moving in the reverse direction, it is convenient to pull the moving rod 13 on the screen 02 to move in the direction close to the storage chamber 3, so that the first partition plate 11 and the second partition plate 12 on the screen 02 can be in the same straight line. Since the process of the adjusting conveyor belt 24 driving the moving rod 13 to move close to the storage chamber 3 is the same as the process of the adjusting conveyor belt 24 driving the moving rod 13 to move away from the storage chamber 3, in this embodiment, the process of the adjusting conveyor belt 24 driving the moving rod 13 to move close to the storage chamber 3 is not described in detail.

[0043] Reference Figures 2 to 5The tensioning assembly 5 includes a tensioning plate 51 slidably connected to the mounting shell 04, a tensioning roller 52 rotatably connected to the tensioning plate 51 and a tensioning spring 53 fixed to the tensioning plate 51. The tensioning roller 52 is arranged between the first adjusting roller 21 and the second adjusting roller 22, and the tensioning roller 52 abuts against the inner side surface of the adjusting conveyor belt 24. The end of the tensioning spring 53 away from the tensioning plate 51 is fixed to the mounting shell 04, so that the tensioning spring 53 is used to drive the tensioning plate 51 and the tensioning roller 52 to move in the direction away from the side of the screen 02, and then when the inclined portion 242 becomes longer, the tensioning roller 52 pulls the adjusting conveyor belt 24 to move in the direction away from the partition assembly 1 under the action of the tensioning spring 53. In the process of pushing the roller 23 to move, the adjusting conveyor belt 24 can always be kept in a tensioned state, so that the connecting block 31 is better located in the connecting groove 32.

[0044] Reference Figures 2 to 5 The linkage assembly 4 includes a first linkage block 41, a second linkage block 42, a linkage shaft 43, a first linkage rod 44 and a second linkage rod 45. The first adjusting roller 21 is rotatably connected to the first linkage block 41, and the first linkage block 41 is slidably connected to the mounting shell 04 along the width direction of the screen 02. The second adjusting roller 22 is rotatably connected to the second linkage block 42, and the second linkage block 42 is slidably connected to the mounting shell 04 along the width direction of the screen 02; the linkage shaft 43 is fixedly installed on the second linkage rod 45, two first linkage rods 44 are provided, and the two first linkage rods 44 are both slidably connected to the second linkage rod 45 along the length direction of the screen 02, and one end of one first linkage rod 44 away from the second linkage rod 45 is hinged on the first linkage block 41, and the other end of the first linkage rod 44 away from the second linkage rod 45 is hinged on the second linkage block 42. At the same time, a linkage motor is arranged on the mounting shell 04, and the output shaft of the linkage motor is fixedly connected to the linkage shaft 43. The linkage motor rotates to drive the linkage shaft 43 and the second linkage rod 45 to rotate, thereby adjusting the positions of the first adjusting roller 21 and the second adjusting roller 22.

[0045] Reference Figure 2 and Figure 6 A scattering assembly 7 for scattering the thrown materials is provided on the partition assembly 1. The scattering assembly 7 includes a scattering spring 71 fixedly mounted on the first partition plate 11 and a scattering plate 72 fixed on the scattering spring 71, so that the end of the scattering spring 71 and the first partition plate 11 is fixed as a fixed end, and the end of the scattering plate 72 is fixed as a free end. Then, while the screen 02 and the relaxation screen body 01 vibrate, the free end of the scattering spring 71 will drive the scattering plate 72 to swing, and then the thrown materials will be scattered, thereby reducing the accumulation of the fallen materials, and thus improving the screening efficiency of the materials. In this embodiment, a scattering assembly 7 is provided on each of the first partition plate 11 and the second partition plate 12, so that the screening efficiency of the materials is better.

[0046] The implementation principle of an anti-clogging relaxation screen in an embodiment of the present application is as follows: in the initial state, the screening channel 05 is in a straight state, at which time the screening channel 05 is the shortest, and the connecting block 31 is in the connecting groove 32. When the length of the screening channel 05 needs to be increased, the connecting block 31 is driven to rotate by adjusting the conveyor belt 24, so that the connecting block 31 drives the moving rod 13 above the screen 02 to move at the same time. When the moving rod 13 close to the second adjusting roller 22 moves to the extreme position, the adjacent first partition plate 11 and the second partition plate 12 are vertically arranged, and then the control component 6 drives the push roller 23 to move in the direction close to the first adjusting roller 21. At this time, the moving rod 13 and the connecting block 31 in the extreme position will be separated, and then in the subsequent movement of the moving rod 13, the moving rod 13 in the extreme position will not be driven to move, thereby making it more convenient to adjust the length of the screening channel 05. When reducing the length of the screening channel 05, the distance between the axis of the first adjusting roller 21 and the side of the screen 02 is greater than the distance between the axis of the second adjusting roller 22 and the side of the screen 02, and the control component 6 drives the push roller 23 to move toward the second adjusting roller 22, and at this time, it can drive the moving rod 13 at the limit to move toward the first adjusting roller 21.

[0047] Embodiment 2: The difference from the first embodiment is that the material on the screen 02 can be pushed to move along the width direction of the screen 02, thereby improving the screening efficiency of the material.

[0048] Reference Figure 2 and Figure 7 The mounting shell 04 is slidably connected to the mounting plate 03 along the width direction of the screen 02. A swing assembly 8 for driving the mounting shell 04 to reciprocate is provided on the mounting plate 03.
