DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides Figure 1-4 The wood fiber screening device with adjustable mesh size shown includes a vibration motor 1 and a limit seat 4 installed on the upper side of the vibration motor 1;
[0025] A screening frame 5 is provided on the upper side of the limiting seat 4;
[0026] A screen 7 is fixedly connected between the inner walls at the left and right ends of the screening frame 5;
[0027] An adjusting plate 6 is arranged at the lower side of the screen 7, a fixing column 13 is arranged between the screen 7 and the adjusting plate 6, a fixing bolt 12 is arranged on the upper end outer wall of the fixing column 13 to penetrate downward to limit the position of the adjusting plate 6, an adjusting ring 14 is connected to the circular outer wall of the screening frame 5 to adjust the position of the adjusting plate 6, a discharge port 15 is arranged on the right end circular outer wall of the screening frame 5 to discharge the screened wood fiber, the vibration motor 1 is electrically connected to the external power supply, and when screening wood fiber, the mesh size of the screen 7 is first adjusted, and the adjustment is made by rotating clockwise or counterclockwise. The ring 14 makes the meshes on the adjustment plate 6 and the meshes on the screen 7 staggered, limiting the holes of the screen 7, and then the fixing bolt 12 is screwed into the fixing column 13 by clockwise rotation to limit the position of the adjustment plate 6, and then the wood fiber to be screened is placed on the screen 7, and the screening frame 5 and the limit seat 4 are connected, and then the vibration motor 1 is started to vibrate, and the wood fiber is screened from the screen 7 and discharged from the discharge port 15. After the screening is completed, the vibration motor 1 is turned off, and the unscreened wood fiber in the screening frame 5 is taken out, or a secondary screening is performed;
[0028] A plurality of rubber balls 16 are equidistantly arranged on the lower side of the adjustment plate 6 from left to right, and a filter screen 17 is arranged between the lower sides of the plurality of rubber balls 16 to provide a placement position for the rubber balls 16. During the vibration of the vibration motor 1, the rubber balls 16 will vibrate on the filter screen 17, and the fibers blocked inside the screen 7 will be vibrated out, thereby avoiding the blockage and accumulation of wood fibers.
[0029] like Figure 4 As shown, a connecting rope 18 is fixedly connected between multiple rubber balls 16 and the filter screen 17 to limit the activity space of the rubber balls 16, a positioning groove 20 is opened on the circular inner wall of the screening frame 5, and a fixing frame 19 is arranged inside the positioning groove 20 to limit the position of the filter screen 17, and buffer pads 21 are fixedly connected to the inner walls at the upper and lower ends of the positioning groove 20 to buffer the amplitude of the fixing frame 19 when it shakes up and down.
[0030] During the vibration of the rubber ball 16, the connecting rope 18 limits the moving range of the rubber ball 16 to prevent multiple rubber balls 16 from piling up. During the vibration of the filter screen 17, the fixing frame 19 is driven to vibrate synchronously to provide power for the vibration of the rubber ball 16. During the vibration of the fixing frame 19, when it collides with the positioning groove 20, it will hit the buffer pad 21 to reduce the noise during the collision.
[0031] like Figure 4 As shown, the vertical length of the fixing frame 19 is smaller than the vertical length of the positioning groove 20, and the buffer pad 21 is made of rubber material.
[0032] This allows the fixing frame 19 to vibrate up and down more stably. The buffer pad 21 made of rubber material has good impact force absorption performance, reducing the noise of the fixing frame 19 when it impacts.
[0033] like Figure 1 As shown, the lower outer wall of the vibration motor 1 is fixedly connected with a base 2 to limit the installation position of the vibration motor 1, and a plurality of buffer springs 3 are fixedly connected between the base 2 and the limit seat 4 to reduce the vibration amplitude emitted by the vibration motor 1. The uppermost sides of the circular outer walls of the limit seat 4 and the screening frame 5 are fixedly connected with a baffle 8, and the upper side of the screening frame 5 is threadedly connected with a top cover 9.
[0034] When the vibration motor 1 is working, the vibration amplitude can be reduced by the buffer spring 3 to avoid excessive vibration amplitude, which may cause the screening frame 5 to shake too much and hit nearby workers.
[0035] like Figure 1 As shown, an observation port 10 is provided on the outer wall of the upper end of the top cover 9, and a fixed cover 11 is internally threadedly connected to the observation port 10 to cover the observation port 10. Two screening frames 5 are provided, and the top cover 9 and the screening frame 5, and the screening frame 5 and the limit seat 4 are all threadedly connected and fixed to the baffle 8.
[0036] When the vibration motor 1 is stopped, the fixed cover 11 can be opened, and the screening state of the wood fiber inside the screening frame 5 can be observed through the observation port 10 to determine whether the screening operation needs to be continued. When connecting and assembling between the top cover 9 and the screening frame 5 and between the screening frame 5 and the limit seat 4, the top cover 9 and the screening frame 5 and between the screening frame 5 and the limit seat 4 are threadedly connected to the corresponding baffle 8 to complete the assembly.
[0037] The implementation principle of this embodiment is as follows: when screening wood fibers, first adjust the mesh size of the screen 7, and rotate the adjusting ring 14 clockwise or counterclockwise to make the mesh holes on the adjusting plate 6 and the mesh holes on the screen 7 staggered and placed to limit the holes of the screen 7, and then rotate the fixing bolt 12 clockwise and screw it into the fixing column 13 to limit the position of the adjusting plate 6, and then place the wood fibers to be screened on the screen 7, and connect the screening frame 5 and the limiting seat 4, and then start the vibration motor 1 to vibrate, so that the wood fibers are screened from the screen 7 and discharged from the discharge port 15. After the screening is completed, turn off the vibration motor 1, take out the unscreened wood fibers in the screening frame 5, or perform secondary screening. During the vibration of the vibration motor 1, the rubber ball 16 will vibrate on the filter 17 to vibrate the fibers blocked in the screen 7, so as to avoid the blockage and accumulation of wood fibers.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
