Description

Technical Field

[0001] The utility model relates to the field of plastic particles, in particular to a plastic particle screening machine. Background Art

[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic particles include general-purpose plastics, engineering plastics, and special plastics. In today's society, due to the increasing awareness of environmental protection, recycled plastic particles have a wide range of applications. In daily life, recycled particles can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and various plastic products.

[0003] Existing plastic particles need to be preliminarily screened before they can be produced and processed. Since the diameters of plastic particles are different, multiple screens with different inner diameters are needed in the screening process. At the same time, workers are required to perform screening work back and forth many times to facilitate subsequent batch processing. At that time, most of the screening was done by manpower, which increased the overall screening burden and reduced the overall screening efficiency.

[0004] In summary, when facing plastic particles with different inner diameters during the screening process of plastic particles, the screening work is mostly carried out repeatedly by manpower, thereby increasing the overall screening burden and reducing the overall screening efficiency. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a plastic particle screening machine to solve the technical problem that the screening work is mostly carried out repeatedly by manpower during the screening process, thereby increasing the overall screening burden and reducing the overall screening efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic particle screening machine, comprising a box body, a frame is arranged on the top of the box body, and a first screen is arranged in the frame for reciprocating sliding, a discharge pipe is arranged at the bottom of the frame, a mounting frame which cooperates with the discharge pipe is arranged obliquely in the box body, and a second screen is arranged on the inclined surface of the mounting frame, a second collecting box is slidably arranged at the bottom of the second screen in the box body, and a first collecting box is slidably arranged on one side thereof.

[0007] By adopting the above technical solution, the plastic particles to be screened are discharged into the frame, and the plastic particles are screened once under the action of the first screen. Then, the screened plastic particles will impact the mounting frame at the bottom through the discharge pipe, and at the same time, a second screen is obliquely arranged on the mounting frame, thereby achieving a secondary screening under the action of the second screen, further improving the overall screening effect, and the plastic particles screened by the second screen will fall into the second collection box at the bottom, and the remaining plastic particles will slide to the first collection box on one side, which greatly reduces the workload of the staff in the process and improves the overall screening efficiency.

[0008] The utility model is further configured that a spiral flow channel is arranged inside the discharge pipe, and the other end of the discharge pipe is arranged to be inclined downward.

[0009] By adopting the above technical solution, when the plastic particles screened by the first screen enter the discharge pipe, the spiral flow channel will increase the overall sliding speed of the plastic particles, thereby increasing the impact force of the plastic particles. Since one end of the discharge pipe is tilted downward, the plastic particles will impact the second screen under the action of the spiral flow channel, thereby further improving the screening effect of the second screen on the plastic particles.

[0010] The utility model is further configured that a stepper motor is arranged on one side of the frame, and a reciprocating screw rod is connected to the frame through the output end of the stepper motor, and the outer wall of the reciprocating screw rod is connected to the first screen.

[0011] By adopting the above technical solution, by starting the stepper motor on one side, the reciprocating screw rod will be driven to rotate under the action of the stepper motor. In this process, the first screen is driven to slide back and forth in the frame, thereby improving the screening effect of the first screen on plastic particles and effectively preventing plastic particles from clogging the first screen.

[0012] The utility model is further configured that a guide rod is arranged on the other side of the reciprocating screw rod in the frame.

[0013] By adopting the above technical solution, the first screen can be limited under the action of the guide rod, thereby ensuring that the first screen will not rotate with the reciprocating screw during rotation, effectively preventing the first screen from rotating with the reciprocating screw.

[0014] The utility model is further configured such that the bottoms of the first collection box and the second collection box are both provided with T-shaped blocks, and the bottoms inside the boxes are provided with T-shaped grooves for the T-shaped blocks to slide.

[0015] By adopting the above technical solution, the sliding stability of the first collection box and the second collection box is ensured under the cooperation of the T-shaped block and the T-shaped groove.

[0016] The utility model is further configured that a damping structure is provided between the T-shaped groove and the T-shaped block.

[0017] By adopting the above technical solution, the damping structure between the two can prevent the two groups of collection boxes from shaking during the screening process, thereby further improving the overall collection effect of the collection boxes.

[0018] The utility model is further configured such that the aperture of the second screen is smaller than the aperture of the first screen.

[0019] By adopting the above technical solution, the plastic particles with larger diameters are screened by the first screen, while the plastic particles with smaller diameters are screened by the second screen.

[0020] The utility model is further configured such that the outer wall of the first screen is provided with a barrier.

[0021] By adopting the above technical solution, plastic particles can be stored under the action of the enclosure, effectively preventing the plastic particles from slipping out of the first screen during the reciprocating sliding of the first screen, and further reducing the difficulty of subsequent staff in collecting the plastic particles on the first screen.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model has a first screen that slides back and forth in a frame. The staff discharges the plastic particles to be screened into the frame, and the plastic particles are screened once under the action of the first screen. Then the screened plastic particles will impact the mounting frame at the bottom through a discharge pipe, and a second screen is obliquely arranged on the mounting frame, thereby achieving a secondary screening under the action of the second screen, further improving the overall screening effect, and the plastic particles screened by the second screen will fall into the second collection box at the bottom, and the remaining plastic particles will slide to the first collection box on one side, greatly reducing the workload of the staff in the process and improving the overall screening efficiency.

[0030] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] Embodiment 1

[0033] A plastic particle screening machine, such as Figure 1-Figure 4 As shown, it includes a box body 1, a frame 4, a screening mechanism, a collecting mechanism and a sliding mechanism. A frame 4 is provided at the top of the box body 1, and a first screen 3 is slidably provided in the frame 4. The staff uniformly discharges the screened plastic particles to the top of the first screen 3, and then starts the stepper motor 2 on one side of the frame 4. Since the output end of the stepper motor 2 passes through the frame 4 and is connected to a reciprocating screw 10, and the outer wall of the reciprocating screw 10 is connected to the first screen 3, the reciprocating screw 10 is driven to rotate under the action of the stepper motor 2. In this process, the first screen 3 is driven to slide back and forth in the frame 4, thereby improving the screening effect of the first screen 3 on the plastic particles, and effectively preventing the plastic particles from clogging the first screen 3. The plastic particles passing through the first screen 3 are discharged to the bottom of the frame 4, and a discharge pipe 5 is provided at the bottom of the frame 4, so that the screened plastic particles are discharged through the discharge pipe 5;

[0034] Since a mounting frame 7 cooperating with the discharge pipe 5 is obliquely arranged in the box body 1, and a second screen 9 is arranged on the inclined surface of the mounting frame 7, secondary screening is achieved under the action of the second screen 9, thereby further improving the overall screening effect, and a second collecting box 8 is slidably arranged at the bottom of the second screen 9 in the box body 1, and a first collecting box 6 is slidably arranged on one side thereof, the plastic particles screened by the second screen 9 will fall into the second collecting box 8 at the bottom, and the remaining plastic particles will slide to the first collecting box 6 on one side, which greatly reduces the workload of the staff in the process and improves the overall screening efficiency.

[0035] See also Figure 3 A guide rod is provided on the other side of the reciprocating screw 10 in the frame 4, and the first screen 3 can be limited by the guide rod, thereby ensuring that the first screen 3 will not rotate with the reciprocating screw 10 during its rotation, thereby effectively preventing the first screen 3 from rotating with the reciprocating screw 10.

[0036] See also Figure 1 and Figure 4 A T-shaped block 11 is provided at the bottom of the first collection box 6 and the second collection box 8, and a T-shaped slot 12 for the T-shaped block 11 to slide is provided at the bottom of the box body 1. The cooperation of the T-shaped block 11 and the T-shaped slot 12 ensures the sliding stability of the first collection box 6 and the second collection box 8, and a damping structure is provided between the T-shaped slot 12 and the T-shaped block 11. The damping structure between the two can prevent the two groups of collection boxes from shaking during the screening process, thereby further improving the overall collection effect of the collection box.

[0037] Embodiment 2

[0038] like Figure 5 A plastic particle screening machine shown in the figure has an overall structure similar to that of the first embodiment, wherein a spiral flow channel 13 is arranged inside the discharge pipe 5, and the other end of the discharge pipe 5 is arranged to be inclined downward. When the plastic particles screened by the first screen 3 enter the discharge pipe 5, the spiral flow channel 13 will increase the overall sliding speed of the plastic particles, thereby increasing the impact force of the plastic particles. Since one end of the discharge pipe 5 is arranged to be inclined downward, the plastic particles will impact the second screen 9 under the action of the spiral flow channel 13, thereby further improving the screening effect of the second screen 9 on the plastic particles.

[0039] The working principle of the utility model is as follows: when in use, the plastic particles to be screened are uniformly discharged onto the first screen 3 in the frame 4, and the first screen 3 is driven to slide back and forth under the action of the stepper motor 2, thereby realizing a single screening of the plastic particles, and the screened plastic particles are discharged to the bottom of the frame 4, and impacted toward the mounting frame 7 on one side through the action of the discharge pipe 5. Since a second screen 9 is provided on the mounting frame 7, a secondary screening of the plastic particles is completed, thereby improving the overall screening effect, and the plastic particles screened by the second screen 9 are discharged into the second collection box 8 at the bottom, and the remaining plastic particles slide into the first collection box 6 on the other side, thereby realizing the unified collection and processing of the screened plastic particles, greatly reducing the overall screening burden.

[0040] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
