Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to an anti-clogging plastic particle vibrating screen. Background Art

[0002] The plastic particle vibrating screen is a kind of mechanical equipment specially used for screening plastic particles. It makes the plastic particles move and jump on the screen through vibration, so as to classify particles of different particle sizes or remove impurities. The vibrating screen is widely used in the fields of plastic processing, recycling, composite material manufacturing, etc. to ensure the quality and uniformity of plastic particles. The plastic particle vibrating screen mainly consists of a screen mesh, a vibrating motor, a screen frame, a shock absorption device, and a feeding and discharging structure. Compared with other screening methods, the advantage of vibrating screening is that it can quickly screen a large number of plastic particles through high-frequency vibration, thereby improving production efficiency. It can flexibly adjust the screen aperture according to different requirements to achieve fine screening. Moreover, the vibrating screen has a simple structure, stable operation, convenient daily maintenance, and low use cost.

[0003] In the existing plastic particle vibrating screening process, there are usually problems such as plastic particle agglomeration and clogging of the screen holes. In order to reduce the occurrence of screen hole clogging, generally, a multi-layer vibrating screen is used to screen plastic particles, and the plastic particles are divided into multiple levels for screening. Each section of the screen mesh processes particles of different sizes, so as to reduce the chance of fine particles clogging on the screen mesh. However, the above-mentioned vibrating screen is still prone to screen hole clogging during the actual screening process, seriously reducing the screening efficiency of the vibrating screen for plastic particles. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an anti-clogging plastic particle vibrating screen for the technical problem that the existing vibrating screen is prone to screen hole clogging.

[0005] An anti-clogging plastic particle vibrating screen includes a base, a first screen frame, a second screen frame, a vibrating motor, and a shock absorption assembly. The first screen frame is connected to the base through the shock absorption assembly. The second screen frame is sleeved inside the first screen frame and connected to the inner wall of the first screen frame. The screen mesh of the second screen frame communicates with the first screen frame at the bottom side. The vibrating motor is installed on the first screen frame.

[0006] The first screen frame is provided with a first cover plate, a first frame door, and several elastic bodies. The first cover plate is arranged on the top of the first screen frame in cooperation with the screen mesh of the second screen frame. The first frame door is hinged at the feeding end of the first screen frame. Thus, the first screen frame, in cooperation with the second screen frame, the first cover plate, and the first frame door, forms a relatively closed space. Several elastic bodies are accommodated in the first screen frame.

[0007] In one embodiment, the above-mentioned second sieve frame is provided with a second cover plate and a second frame door. The second cover plate is arranged at the top of the second sieve frame; the second frame door is hingedly arranged at the discharging end of the second sieve frame.

[0008] In one embodiment, the above-mentioned first sieve frame is further provided with a plurality of balance beams and a plurality of first elastic members. The plurality of balance beams are respectively arranged on the outer sides of the side walls of the first sieve frame, and each balance beam is connected to the side wall surface of the first sieve frame through two first elastic members.

[0009] In one embodiment, the above-mentioned shock absorption assembly is arranged as a plurality of second elastic members, and the first sieve frame is connected to the base through the plurality of second elastic members.

[0010] In one embodiment, the above-mentioned base is further provided with a blanking chute, and the blanking chute is correspondingly arranged at the bottom side of the first sieve frame. The first sieve frame is communicated with the blanking chute through its sieve mesh.

[0011] In one embodiment, the inner surface of the above-mentioned first frame door is provided with a first guide plate, and the first guide plate is arranged on both sides of the first frame door.

[0012] In one embodiment, the inner surface of the above-mentioned second frame door is provided with a second guide plate, and the second guide plate is arranged on both sides of the second frame door.

[0013] In one embodiment, the above-mentioned second sieve frame is provided with a feed hopper. The feed hopper is arranged at one end of the top side of the second sieve frame, and the feed hopper is communicated with the inside of the second sieve frame through the second cover plate.

[0014] In one embodiment, the above-mentioned second sieve frame is provided with two connecting columns. The two connecting columns are respectively arranged through both ends of the second sieve frame, and both ends of each connecting column are connected to the inner wall of the first sieve frame.

[0015] In one embodiment, the above-mentioned first sieve frame is provided with two mounting plates, and the two mounting plates are respectively arranged at the tops of the two side walls of the first sieve frame for mounting vibration motors.

[0016] In one embodiment, the above-mentioned first sieve frame is further provided with a support column. The support column is arranged between the two mounting plates, and both ends of the support column are connected to the opposite side surfaces of the two mounting plates.

[0017] The above anti-clogging plastic particle vibrating screen drives the first screen frame to vibrate through a vibrating motor, and at the same time drives the second screen frame to vibrate to screen the plastic particles. Among them, the plastic particles are first initially screened by the second screen frame, and the plastic particles passing through the second screen frame fall into the first screen frame for secondary screening, so as to achieve multi-stage screening of the plastic particles. In this process, the second screen frame can initially screen the plastic particles, and the plastic particles with larger particle sizes remain on the second screen frame, while most plastic particles can quickly pass through the second screen frame and fall into the first screen frame, thereby largely avoiding blockage of the plastic particles at the second screen frame. At the same time, several elastomers can bounce between the screen of the first screen frame, the first cover plate and the screen of the second screen frame, thereby forming an impact on the screen of the first screen frame and the screen of the second screen frame, and then knocking out the plastic particles blocked in the first screen frame and the second screen frame from the screen holes of the corresponding screen, thereby further avoiding the situation of plastic particle blockage.

[0025] Please refer to Figure 1, the present utility model discloses an anti-clogging plastic particle vibrating screen, which includes a base 100, a first sieve frame 200, a second sieve frame 300, a vibration motor 400 and a shock absorption assembly. The first sieve frame 200 is connected to the base 100 through the shock absorption assembly. The second sieve frame 300 is sleeved inside the first sieve frame 200 and connected to the inner wall of the first sieve frame 200. The sieve mesh of the second sieve frame 300 communicates with the first sieve frame 200 at the bottom side, so that the plastic particles passing through the second sieve frame 300 can fall into the first sieve frame 200. The vibration motor 400 is installed on the first sieve frame 200. Thus, the vibration motor 400 can drive the first sieve frame 200 to vibrate, and at the same time drive the second sieve frame 300 to vibrate to screen the plastic particles. Among them, the plastic particles are first screened by the second sieve frame 300, and the plastic particles passing through the second sieve frame 300 fall into the first sieve frame 200 for secondary screening, so as to realize the multi-stage screening of plastic particles. In this process, the second sieve frame 300 can perform primary screening on the plastic particles. The plastic particles with larger particle sizes remain in the second sieve frame 300, while most plastic particles can quickly pass through the second sieve frame 300 and fall into the first sieve frame 200, thereby largely avoiding the blockage of plastic particles at the second sieve frame 300. At the same time, the first sieve frame 200 is provided with a first cover plate 210, a first frame door 220 and a number of elastic bodies (not shown). The first cover plate 210 is arranged on the top of the first sieve frame 200 in cooperation with the sieve mesh of the second sieve frame 300. The first frame door 220 is hingedly arranged at the discharging end of the first sieve frame 200. Thus, the first sieve frame 200 cooperates with the second sieve frame 300, the first cover plate 210 and the first frame door 220 to form a relatively closed space. A number of elastic bodies are accommodated in the first sieve frame 200. In practical applications, the vibration motor 400 drives the first sieve frame 200 and the second sieve frame 300 to vibrate. A number of elastic bodies can jump between the sieve mesh of the first sieve frame 200, the first cover plate 210 and the sieve mesh of the second sieve frame 300, thereby forming an impact on the sieve mesh of the first sieve frame 200 and the sieve mesh of the second sieve frame 300, and further knocking out the plastic particles blocked in the first sieve frame 200 and the second sieve frame 300 from the sieve holes of the corresponding sieve meshes, thereby further avoiding the blockage of plastic particles.

[0026] Further, the second sieve frame 300 is provided with a second cover plate 310 and a second frame door 320. The second cover plate 310 is arranged on the top of the second sieve frame 300. The second frame door 320 is hingedly arranged at the discharging end of the second sieve frame 300. The second cover plate 310 can prevent the plastic particles inside from flying out from the top of the second sieve frame 300 during the vibration of the second sieve frame 300. The second frame door 320 can cooperate with the second cover plate 310 to make the second sieve frame 300 form a relatively closed space. After the screening is completed, the second frame door 320 is opened, and the plastic particles inside the second sieve frame 300 can be discharged through the discharging end at the second frame door 320.

[0027] Furthermore, the first sieve frame 200 is also provided with a plurality of balance beams 230 and a plurality of first elastic members 240. The plurality of balance beams 230 are respectively arranged outside the side walls of the first sieve frame 200. Moreover, each balance beam 230 is connected to the surface of the side wall of the first sieve frame 200 through two first elastic members 240. Thus, during the vibration of the first sieve frame 200, the plurality of balance beams 230 can balance the vibration force and reduce the influence of the eccentric force, thereby maintaining the stability of the first sieve frame 200 and the second sieve frame 300.

[0028] Furthermore, the shock-absorbing assembly is arranged as a plurality of second elastic members 500. The first sieve frame 200 is connected to the base 100 through the plurality of second elastic members 500, thereby reducing the vibration of the base 100 relative to the bottom surface and ensuring the installation stability of the overall vibrating screen.

[0029] Furthermore, the base 100 is also provided with a blanking chute 110. The blanking chute 110 is correspondingly arranged at the bottom side of the first sieve frame 200. The first sieve frame 200 is communicated with the blanking chute 110 through its sieve mesh, so that the plastic particles sieved in the first sieve frame 200 can be collected in the blanking chute 110 for independent blanking.

[0030] Furthermore, a first guiding plate 221 is arranged on the inner surface of the first frame door 220. The first guiding plate 221 is arranged on both sides of the first frame door 220. Thus, after the first sieve frame 200 completes the screening work and the first frame door 220 is opened, it can serve as a blanking plate to guide the plastic particles to drop.

[0031] Furthermore, a second guiding plate 321 is arranged on the inner surface of the second frame door 320. The second guiding plate 321 is arranged on both sides of the second frame door 320. Thus, after the second sieve frame 300 completes the screening work and the second frame door 320 is opened, it can serve as a blanking plate to guide the plastic particles to drop.

[0032] Furthermore, the second sieve frame 300 is provided with a feed hopper 330. The feed hopper 330 is arranged at one end of the top side of the second sieve frame 300. Moreover, the feed hopper 330 is communicated with the inside of the second sieve frame 300 through the second cover plate 310. Thus, the plastic particles can be fed into the second sieve frame 300 through the feed hopper 330 for the primary screening process.

[0033] Furthermore, the second sieve frame 300 is provided with two connecting columns 340. The two connecting columns 340 respectively penetrate through both ends of the second sieve frame 300. Both ends of each connecting column 340 are connected to the inner wall of the first sieve frame 200, thereby strengthening the connection strength between the second sieve frame 300 and the first sieve frame 200.

[0034] Further, the first sieve frame 200 is provided with two mounting plates 250 which are respectively arranged at the tops of the two side walls of the first sieve frame 200 for mounting the vibration motor 400. Specifically, the first sieve frame 200 is further provided with support columns 260 which are arranged between the two mounting plates 250, and both ends of the support columns 260 are connected to the opposite side surfaces of the two mounting plates 250, thereby strengthening the connection strength between the vibration motor 400 and the first frame body, and thus ensuring the output effectiveness of the vibration motor 400 to the first sieve frame 200.

[0035] In summary, the anti-blocking plastic particle vibrating sieve disclosed by the present utility model vibrates the first sieve frame through a vibration motor, and at the same time drives the second sieve frame to vibrate to screen the plastic particles. Among them, the plastic particles are first initially screened by the second sieve frame, and the plastic particles passing through the second sieve frame fall into the first sieve frame for secondary screening, thereby realizing multi-stage screening of the plastic particles. In this process, the second sieve frame can perform primary screening on the plastic particles, and the plastic particles with larger particle sizes remain on the second sieve frame, while most plastic particles can quickly pass through the second sieve frame and fall into the first sieve frame, thereby largely avoiding blockage of the plastic particles at the second sieve frame. At the same time, several elastic bodies can jump between the sieve mesh of the first sieve frame, the first cover plate and the sieve mesh of the second sieve frame, thereby forming an impact on the sieve mesh of the first sieve frame and the sieve mesh of the second sieve frame, and then knocking out the plastic particles blocked in the first sieve frame and the second sieve frame from the sieve holes of the corresponding sieve meshes, thereby further avoiding the situation of plastic particle blockage.

[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0037] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
