In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0024] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0027] See also Figure 1-7 , the utility model provides a technical solution:
[0028] A thermoplastic rubber particle filtering screen device includes a mounting frame 1 and a vibration motor 16. The mounting frame 1 includes a main frame 101 and a sub-frame 102. A card slot 2 is provided on one side of the mounting frame 1. A first through hole 3 connected to the card slot 2 is provided on the inner side of the mounting frame 1. A mounting block 4 is connected to the inner side of the card slot 2 arranged on the inner side of the main frame 101. A filter plate 5 is fixedly connected between a group of mounting blocks 4. A second through hole 6 with an equal aperture is provided on the inner side of the mounting block 4. A symmetrical elastic connecting rod 7 is provided on the inner side of the second through hole 6 and the first through hole 3. The elastic connecting rod 7 is connected to the inner side of the card slot 2. One end of the connecting rod 7 is fixedly connected to an arc-shaped positioning block 8, and the end of the elastic connecting rod 7 away from the arc-shaped positioning block 8 is fixedly connected to a screw rod 9, and a nut 10 is spirally connected to the outer side of the screw rod 9. A return spring 11 is fixedly connected between a group of elastic connecting rods 7, and fixed blocks 12 are fixedly connected to both sides of the sub-frame 102. The bottom of the fixed block 12 is fixedly connected to a buffer spring 13, and the end of the buffer spring 13 away from the fixed block 12 is fixedly connected to a mounting plate 15. The lower end surface of the mounting plate 15 is fixedly connected to the output shaft of the vibration motor 16, and a storage box 17 is arranged between a group of vibration motors 16.
[0029] The return springs 11 are evenly arranged, and the nut 10 fits against the outer wall of the main frame 101. This arrangement allows the mounting block 4 and the filter plate 5 to be mounted on the inner side of the main frame 101 through the cooperation of the nut 10 and the screw 9. The sub-frame 102 is arranged at the bottom of the main frame 101, and the main frame 101 and the sub-frame 102 are fixedly connected. This arrangement allows that when the filter plate 5 positioned by the mounting block 4 on the inner side of the main frame 101 is damaged, a new filter plate 5 and the mounting block 4 are first installed on the inner side of the sub-frame 102. The fixing block 12 is fixedly connected with a damping rod 14. The end of the damping rod 14 away from the fixed block 12 is fixedly connected to the mounting plate 15, and the buffer spring 13 is arranged on the outside of the damping rod 14. This arrangement enables the damping rod 14 and the buffer spring 13 to reduce the shock of the fixed block 12 and the mounting frame 1, so that no violent vibration occurs under the action of the vibration motor 16, thereby causing damage to the filter plate 5 and the mounting block 4; the size of the cross-sectional circle radius of the first through hole 3 is equal to the size of the cross-sectional circle radius of the second through hole 6. This arrangement enables the elastic connecting rod 7 to be simultaneously arranged on the inner sides of the first through hole 3 and the second through hole 6.
[0030] Working process: All electrical appliances in the present invention are provided with an external power supply or a built-in battery. When the thermoplastic rubber particle filter screen device is used to screen the thermoplastic rubber particles, the vibration motor 16 is started, so that the vibration motor 16 drives the mounting plate 15 to vibrate, and the mounting plate 15 acts on the buffer spring 13 and the damping rod 14. The buffer spring 13 and the damping rod 14 act on the fixing block 12. The fixing block 12 acts on the mounting frame 1. The mounting frame 1 drives the mounting block 4 and the filter plate 5 to vibrate, so that the thermoplastic rubber particles can pass through the filter. The filter plate 5 is screened, and the damping rod 14 and the buffer spring 13 can reduce the shock of the fixing block 12 and the mounting frame 1, so that no violent vibration occurs under the action of the vibration motor 16, thereby causing damage to the filter plate 5 and the mounting block 4. The thermoplastic rubber particles screened by the filter plate 5 will fall into the storage box 17 at the bottom of the filter plate 5 and are collected and processed by the storage box 17. The mounting frame 1 is set as the main frame 101 and the sub-frame 102. When the filter plate 5 positioned by the mounting block 4 on the inner side of the main frame 101 is damaged, a new filter plate 5 and the mounting block 4 are first replaced. 4 is installed on the inner side of the sub-frame 102 so that the mounting block 4 is completely engaged with the inner side of the card slot 2, and then the nut 10 set on the outer side of the main frame 101 is rotated to make the nut 10 disengage from the screw rod 9, and then the elastic connecting rod 7 is pressed in the direction of mutual approach, so that the return spring 11 is squeezed by the elastic connecting rod 7. At this time, the arc-shaped positioning block 8 also moves in the direction of relative approach, and then the screw rod 9 is pulled outward, and the screw 9 drives the elastic connecting rod 7 to disengage from the first through hole 3 and the second through hole 6 in turn, and the arc-shaped positioning block 8 will gradually enter the first through hole 3 and the second through hole 6. When the arc-shaped positioning block 8 is completely separated from the first through hole 3, the positioning of the mounting block 4 is cancelled, and the arc-shaped positioning block 8 and the elastic connecting rod 7 are reversely placed in the first through hole 3 on the inner side of the sub-frame 102, thereby realizing the positioning of the mounting block 4 and the filter plate 5 placed on the inner side of the sub-frame 102. The operation is repeated. When the nut 10 and the like are separated from the main frame 101, the mounting block 4 and the filter plate 5 on the inner side of the main frame 101 can be removed, so that the mounting block 4 and the filter plate 5 can be disassembled and replaced without stopping the machine, and will not affect the work progress.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
