[0002] Insulating resin screening involves pouring the resin raw material onto a sieve tray and removing larger particles and impurities through a filter screen, thus maintaining the uniform size of the raw material particles and ensuring stability during the insulating resin processing. However, during the screening process, due to the fine powder on the resin surface, the friction and collision of resin particles as they roll on the sieve tray generate a certain amount of dust. This dust floats in the air, not only polluting the environment but also adversely affecting the health of workers. Utility Model Content

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figure 1-6 As shown, an insulating resin raw material screening device includes:

[0032] Tank 1, with an upper cover 2 on the upper part of the tank 1, and a hopper 21 is snapped onto the upper cover 2;

[0033] Screening rack 31 is installed inside tank 1. Connecting blocks 34 are arranged in a circular array on the screening rack 31. Springs 35 connected to the inside of tank 1 are installed on the connecting blocks 34. Filter screen 30 is installed on the screening rack 31 located directly below the feed hopper 21.

[0034] The drive unit 32 is disposed inside the tank 1 and cooperates with the screening rack 31.

[0035] Specifically, the tank body 1 is provided with a discharge port 12, on which resin particles are poured from the discharge hopper 21 into the tank body 1 and flow onto the filter screen 30. Then, the drive component 32 causes the screening frame 31 to reciprocate inside the tank body 1, so that the resin particles are shaken and screened on the filter screen 30. The resin particles of qualified size flow out from the discharge port 12 for storage. A disc 15 connected to a spring 35 is provided on the tank body 1. Under the elastic action of the spring 35, the screening effect of resin particles is improved. Furthermore, the upper cover 2 fits snugly against the tank body 1, and a sealing ring is provided between the upper cover 2 and the tank body 1 to reduce the phenomenon of dust dispersion.

[0036] As a further embodiment of this utility model, at least two sets of screening racks 31 are provided inside the tank body 1, and a receiving unit 4 is provided between the two screening racks 31. The receiving unit 4 includes a receiving tray 42, a baffle plate 44, and a rotating seat 41 symmetrically arranged on the inner wall of the tank body 1. The rotating seat 41 is rotatably connected to the receiving tray 42. A collection tank 47 is provided between the two receiving trays 42. The baffle plate 44 is slidably connected to the tank body 1, and a connecting rod 43 that engages with the receiving tray 42 is provided on the baffle plate 44. There is a gap between the receiving tray 42 and the tank body 1. The two screening racks 31 can be respectively equipped with filter screens 30 of different specifications (e.g., Figure 3 As shown), the upper filter screen 30 has larger mesh openings, suitable for coarse filtration, while the lower filter screen 30 has smaller mesh openings, suitable for fine filtration of resin raw materials. In the prior art, the resin is first filtered through the coarse screen and then poured into the fine screen for filtration. However, this device reduces the resin particle conversion time and improves the screening efficiency. Furthermore, when the baffle plate 44 slides upward to fully open the placement port 11, the connecting rod 43 will drive the two receiving trays 42 to rotate on the rotating seat 41 until the two receiving trays 42 are in contact, and then the collection tank 47 is locked in place. The material is connected to the receiving ports of the two receiving trays 42 to collect the resin particles screened by the filter screen 30 above the tank 1. The size of the collection tank 47 is smaller than the size of the placement port 11, and the collection tank 47 can be installed and removed from the placement port 11. When screening is performed using two sets of screening racks 31, the baffle plate 44 can be driven to slide down to close the placement port 11. At this time, under the pushing action of the connecting rod 43, the two receiving trays 42 are driven to rotate on the rotating seat 41 to create a gap between the two receiving trays 42, so that the resin particles can fall normally onto the filter screen 30 below.

[0037] As a further embodiment of this utility model, the tank body 1 is provided with a placement opening 11, which cooperates with a baffle plate 44. The baffle plate 44 is larger in shape than the placement opening 11 and can block the placement opening 11.

[0038] As a further embodiment of this utility model, a locking block 46 is provided on the baffle plate 44, and a locking pin 45 that cooperates with the tank body 1 is provided on the locking block 46. When the baffle plate 44 slides to block the placement port 11 or open the placement port 11, the baffle plate 44 can be fixed by the locking pin 45.

[0039] As a further embodiment of this utility model, the screening rack 31 is provided with buckles 311 arranged in a circumferential array, and a fixing ring 312 is engaged on the buckle 311. The filter screen 30 cooperates with the fixing ring 312. At least four buckles 311 are provided, and the fixing ring 312 is fixed to the screening rack 31 by the buckles 311.

[0040] As a further embodiment of this utility model, the driving component 32 includes a motor 325, a support block 329, a turntable 326, and a support frame 324 disposed on the inner wall of the tank 1. The motor 325 is fixed on the support frame 324, and a coupling rod 323 that engages with the turntable 326 is provided on the output end of the motor 325. A connecting rod 3281 that cooperates with the support block 329 is provided at the eccentric part of the turntable 326. The support block 329 is fixed on the screening frame 31. The motor 325 is model number MHMF042L1U4-1116. The motor 325 is used as a power source to control the turntable 326 to rotate on the support frame 324 through the coupling rod 323, so that the connecting rod 3281 drives the screening frame 31 to reciprocate within the tank 1, thereby screening the resin particles in the filter screen 30.

[0041] As a further embodiment provided by this utility model, a screw 327 is provided on the turntable 326, and a slider 328 is threadedly connected to the screw 327. A connecting rod 3281 is engaged with the slider 328. Rotating the screw 327 controls the slider 328 to slide on the turntable 326, thereby adjusting the distance between the slider 328 and the central axis of the turntable 326, which is to adjust the shaking amplitude of the screening rack 31.

[0042] As a further embodiment of this utility model, a through hole 3291 is provided on the support block 329, and the connecting rod 3281 is located inside the through hole 3291. The inner diameter of the through hole 3291 is larger than the diameter of the connecting rod 3281. That is to say, in the prohibited state, the connecting rod 3281 is located at the axis of the through hole 3291, but does not contact the inner wall of the through hole 3291. In the moving state, the connecting rod 3281 reciprocates and contacts the inner wall of the through hole 3291, which further improves the shaking effect of the filter screen 30.

[0043] As a further embodiment of this utility model, a protective sleeve that cooperates with the motor 325 is provided on the support frame 324. A vent plate 321 is provided on one side of the protective sleeve. A vent 13 that cooperates with the vent plate 321 is provided on the tank body 1. The protective cover 322 wraps the entire motor 325 to prevent dust from contacting the motor 325 and improve the protection effect of the motor 325. Furthermore, the vent plate 321 can improve the ventilation effect of the motor 325 and reduce the phenomenon of overheating of the motor 325.

[0044] As a further embodiment of this utility model, the bottom of the tank 1 is provided with support columns 17 arranged in a circular array. One end of the support column 17 is connected to the tank 1, and the other end is connected to the bottom surface or the fixing frame, thereby improving the fixing effect of the tank 1.

[0045] Working principle: First, the upper cover 2 is closed with the tank body 1 so that the opening of the hopper 21 is directly facing the filter screen 30. Then, the resin particles are poured into the hopper 21 and flow down the inclined inner wall of the hopper 21 onto the filter screen 30. The turntable 326 is rotated by the motor 325, and the screening frame 31 is reciprocated by the connecting rod 3281. At the same time, the elastic force of the spring 35 pulls back or pushes the screening frame 31 to improve the screening effect of the resin particles. Furthermore, the upper cover 2 is closed with the tank body 1 to reduce dust dispersion, thereby reducing the impact of dust on workers.

[0046] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
