The diameter of paper litter pellets is generally 2-4mm. When using a linear vibrating screen for screening, due to the light weight and cylindrical or strip shape of the paper pellets, some pellets are easy to get stuck on the vibrating screen, affecting the normal screening process. In order to clean up the stuck pellets, our company has a utility model patent entitled "A Vibrating Screen Device for Paper Cat Litter Pellets" with publication number CN221832779U. However, in the technical solution of this patent, the two sliders of the screen plate cleaning device are driven by two motors respectively. During operation, the sliders are prone to being out of sync, causing jamming and affecting the cleaning of the screen plate. Utility Model Content

[0024] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] like Figure 1 and Figure 3 As shown, this utility model discloses a paper particle vibrating screen device, including a support 1, damping springs 2, a screen box 3, a vibrating motor 4, a cover 5, a screen plate 6, and a screen plate cleaning device 7. The screen box 3 is generally rectangular. Four damping springs 2 are provided, which are respectively located on both sides of the screen box 3 and connected to the outer wall of the screen box 3. The support 1 is a rectangular frame, which includes four support legs. The four support legs are respectively located on both sides of the screen box 3. The four damping springs 2 are correspondingly connected to the four support legs. The four damping springs 2 are connected to the support 1 through the four support legs, thereby connecting the screen box 3 to the support 1. Two vibrating motors 4 are symmetrically arranged at the bottom of the screen box 3. When the two vibrating motors 4 rotate synchronously and in opposite directions, the excitation force generated by their eccentric blocks cancels each other out in the direction parallel to the motor axis, and causes the screen box 3 to produce linear vibration in the direction perpendicular to the motor axis.

[0026] like Figure 3 and Figure 4 As shown, the cover 5 is connected to the screen box 3. The cover 5 is used to cover the upper end of the screen box 3. Two cover windows 52 are movably connected to the cover 5. Opening the cover windows 52 allows you to see the situation inside the screen box 3. One end of the cover 5 is provided with a feed inlet 51. A magnetic frame 53 is provided inside the feed inlet 51. The magnetic frame 53 is a strong magnetic frame produced by Fuci Technology Development (Zibo) Co., Ltd., which contains multiple cylindrical magnetic rods arranged side by side. When the paper particles fall, they pass through the outside of the cylindrical magnetic rods of the magnetic frame 53, which can remove iron filings from the paper particles.

[0027] like Figure 3 and Figure 4As shown, paper particles enter the screen box 3 through the feed inlet 51 and fall onto the screen plate 6. The screen plate 6 is set inside the screen box 3 and includes a first screen 61 and a second screen 62. The first screen 61 and the second screen 62 are detachably connected to the screen box 3 by bolts. The first screen 61 has a first screen hole, and the second screen 62 has a second screen hole. The first screen hole is larger than the second screen hole, so the paper particles are screened into three layers: the largest particles are at the top, the medium-sized particles are in the middle layer, and the smallest loose particles fall to the bottom. The screen box 3 is provided with a discharge port group 32, which includes a first outlet 321, a second outlet 322, and a third outlet 323. The first outlet 321 corresponds to the upper space of the first screen 61, the second outlet 322 corresponds to the upper space of the second screen 62, and the third outlet 323 corresponds to the lower space of the second screen 62. The screened paper particles fall from the corresponding outlets, making it easy for them to enter the next processing flow. Two vibrating motors 4 are connected to the screen box 3 through a guide plate. The shaft of the vibrating motor 4 has an inclination angle relative to the screen surface. Under the combined action of the excitation force and the gravity of the granular material, the paper particles being screened are thrown up and jump forward in a straight line on the screen surface, thereby achieving the purpose of screening and grading the paper particles.

[0028] like Figure 3 and Figure 4 As shown, a height limiting plate 33 is provided inside the screen box 3. The position of the height limiting plate 33 corresponds to the position of the feed inlet 51. There is a gap H between the lower end of the height limiting plate 33 and the upper end face of the first screen 61. The gap is 8 cm ≤ H ≤ 15 cm. In this embodiment, H = 10 cm. When a large number of paper particles fall from the feed inlet 51, the height limiting plate 33 can prevent the excessively tall pile of paper particles from passing through. The height limiting plate 33 includes a first plate body 331 and a brush strip 332. The first plate body 331 is made of rubber. The upper end of the first plate body 331 is connected to the inner wall of the cover 5. The brush strip 332 is connected to the lower end of the first plate body 331. The brush strip 332 is composed of polymer bristles. The brush strip 332 can not only prevent the excessively tall pile of paper particles, but also bend to allow the pile of paper particles to pass through when subjected to excessive pressure from the pile of paper particles, thus preventing the paper particles from being squeezed and protecting them.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, a screen plate cleaning device 7 is connected to the support 1. The screen plate cleaning device 7 includes a first drive assembly 71, a lead screw 72, a slider 73, a working rod 74, and a brush roller 75. Two lead screws 72 are symmetrically arranged on both sides of the screen box 3. Each of the four support legs of the support 1 is provided with a support rod 12. The two ends of the lead screw 72 are movably connected to the corresponding support rod 12. The first drive assembly 71 is connected to the two support rods 12 at one end of the support 1. The first drive assembly 71 includes a first drive motor 711 and two first reducers 712. The two ends of the first drive motor 711 are provided with output shafts that are connected to the corresponding first reducers 712. The first reducers 712 are connected to the lead screw 72 to drive the lead screw 72 to rotate. The lead screw 72 extends along the length of the screen box 3. The slider 73 is movably connected to the lead screw 72. When the lead screw 72 rotates, it drives the slider 73 to move left and right along the length of the screen box 3. Compared with two motors driving two sliders separately, a single drive motor can ensure that the two sliders 73 move synchronously, preventing jamming caused by asynchronous movement on both sides of the screen box 3. The working rod 74 passes through the screen box 3 from the side. Both ends of the working rod 74 are connected to the sliders 73 on both sides of the screen box 3 via intermediate rods 76. The screen box 3 has through slots 31 corresponding to the working rod 74. When the two sliders 73 move left and right, they drive the working rod 74 to move left and right within the two through slots 31. A brush rod 75 is mounted on the working rod 74. The bristles of the brush rod 75 are evenly distributed on the outer circumference of the rod. The brush rod 75 can rotate relative to the working rod 74. The bristles are made of polymer. The working rod 74 is positioned below the screen plate 6. Since the sieve plate 6 includes a first sieve 61 and a second sieve 62, two working rods 74 are also correspondingly provided. The two working rods 74 are distributed in the upper and lower directions and are connected to two sliders 73 respectively. Two brush rollers 75 are attached to the first sieve 61 and the second sieve 62 from below. When the working rods 74 move left and right, the brush rollers 75 scrape the first sieve 61 and the second sieve 62, scraping away the paper particles stuck on the sieve. Since the bristles on the brush rollers 75 can rotate, the cleaning effect on the sieve is better than that of strip brushes. A blocking brush is provided in the through groove 31. The blocking brush is made of polymer bristles. The blocking brush extends towards the middle part of the through groove 31 in the upper and lower directions, covering the hollow part of the through groove 31. When the particles fall from the sieve, the blocking brush can prevent the paper particles from leaking out of the through groove 31. Since the blocking brush is relatively soft, it will not affect the left and right movement of the working rods 74 in the two through grooves 31. A guide rod 77 is provided between the two support rods 12 on the same side of the screen box 3. Two guide rods 77 are provided on one side of the screen box 3. The guide rods 77 are parallel to the lead screw 72. The middle rod 76 is provided with a first through hole corresponding to the guide rods 77. When the slider 73 and the middle rod 76 move left and right, the guide rods 77 play a guiding role.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
