Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically to an integrated screening device for recycling plastics. Background Technology

[0002] With the rapid development of the petroleum industry, the application of plastic products has become increasingly widespread. In some cases, they can even replace metals, wood, paper, etc., bringing great convenience to people's lives. However, with the continuous increase in the consumption of plastic products, the amount of waste plastic is also increasing. Therefore, in order to facilitate the recycling of plastics, integrated screening devices for recycling plastics have been established to screen and process large quantities and various types of plastics.

[0003] A Chinese patent with publication number CN209257283U discloses a screening device for recycling waste plastics that can avoid clogging. The device includes a screening box, a drive motor, a receiving frame, and a suction fan. The drive motor is fixedly installed on top of the screening box, and a rotating shaft is fixedly connected to the bottom of the drive motor. A first screen plate is slidably disposed in the middle of the screening box. The first dust suction port is connected to a dust suction pipe via a connecting conduit, and the bottom of the dust suction pipe is connected to one end of the suction fan. The lower output end of the suction fan is connected to the top of the dust receiving box, which is mounted on a placement plate. This clogging-avoiding screening device for recycling waste plastics includes a suction fan, a first dust suction port, a second dust suction port, and a partition screen. It can effectively absorb the dust generated during screening through the first and second dust suction ports. Simultaneously, the partition screen prevents fallen plastic from being sucked into the dust suction ports, improving the dust removal efficiency of the device.

[0004] The aforementioned patent still has the following shortcomings: it is not convenient to recycle plastic debris. Because plastic debris is lightweight, it is easy to adhere to the screen, especially in dry environments where static electricity is easily generated, which further increases the possibility of adhesion, leading to a decrease in screening efficiency and even screen blockage. Utility Model Content

[0005] This invention provides an integrated screening device for recycling plastics, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides an integrated screening device for recycling plastics, including a housing, and further comprising:

[0008] The feed hopper is rotatably connected to the top of one side of the machine housing, and a drive shaft is rotatably connected inside the feed hopper. A drive motor with an output shaft end connected to the drive shaft is installed on one side of the feed hopper.

[0009] The cutting structure, located on the outside of the drive shaft, is used for cutting plastic.

[0010] The partition netting is fixed to the top inside the casing;

[0011] A vibrating screen is installed inside a casing, and support springs connected to the casing are installed on both sides of the bottom end of the vibrating screen. An electromagnetic vibrator is installed at the bottom end of the vibrating screen, and a discharge port is installed inside one side of the vibrating screen.

[0012] The screen is fixed at the top inside the vibrating screen;

[0013] A rubber sleeve is installed between the vibrating screen and the machine casing;

[0014] The recycling structure is located on both sides of the casing. The recycling structure includes a collection box fixed on both sides of the casing, a box cover installed inside one side of the collection box, a fan installed at the top of one side of the collection box, an exhaust port installed at the top of the fan, an air duct fixed at the top of the other side of the collection box, a filter screen installed at the top inside the collection box, a lifting assembly installed at the bottom of the air duct, and a suction hopper installed at the bottom of the lifting assembly.

[0015] The above technical solution involves using a drive motor to rotate the transmission shaft, which in turn causes the cutting structure to break up the plastic. An electromagnetic vibrator drives a vibrating screen to vibrate at high frequency, which causes the screen to sieve the plastic fragments to the surface. At the same time, a recycling structure collects the plastic fragments.

[0016] Furthermore, the lifting assembly includes a folded tube installed between the suction hopper and the air duct, an electric telescopic rod installed on both sides inside the housing, a guide frame installed on the telescopic end of the electric telescopic rod, a slide rail slidably connected inside one side of the guide frame and connected to the housing, and a fixed frame fixed to one side of the guide frame and connected to the suction hopper.

[0017] The above technical solution uses a fan to generate airflow, which draws plastic fragments from the screen surface into a collection box. The filter then intercepts the plastic fragments, and the height of the suction bucket is adjusted by an electric telescopic rod to achieve dynamic adsorption of fragments of different thicknesses.

[0018] Furthermore, the air duct extends to the outside of the housing and connects to the collection box, and the suction hoppers are evenly distributed inside the housing.

[0019] The above technical solution ensures that the airflow inside the casing can smoothly enter the collection box, effectively improving the recycling efficiency of plastic fragments. The evenly spaced distribution of the suction buckets allows the plastic fragments on the screen to be more fully adsorbed and collected.

[0020] Furthermore, the folded tube is a hollow tubular structure with a wrinkled surface, and it is a telescopic structure.

[0021] Through the above technical solution, the flexibility of the folded tube ensures that the connection between the air duct and the suction hopper remains stable and reliable under different working conditions.

[0022] Furthermore, the cutting structure includes a fixing strip fixed to the outside of the drive shaft, a blade holder mounted on the top of the fixing strip, a cutter detachably mounted on one side of the blade holder, and a fixing bolt inserted inside the cutter.

[0023] The above technical solution uses a drive shaft to drive a cutter to cut plastic. By adjusting the number and spacing of the cutters, the size of the plastic fragments can be adjusted.

[0024] Furthermore, the cutter is mounted on one side of the cutter holder by fixing bolts, and the cutter holder is evenly distributed on the surface of the fixing strip.

[0025] The above technical solution makes the replacement and adjustment of the cutter simple and quick. The evenly spaced distribution of the cutter holders ensures the uniformity and stability of the cutter.

[0026] The above-described solution of this utility model has at least the following beneficial effects:

[0027] 1. This utility model uses a fan to generate airflow, which draws plastic fragments from the screen surface into a collection box. The filter then intercepts the plastic fragments, thereby realizing the plastic collection function of this device. It can significantly improve screening efficiency, ensure that fine fragments are effectively collected and avoid omissions, and at the same time help to operate in a closed environment, reduce environmental pollution and protect the health of operators.

[0028] 2. This utility model uses a drive shaft to drive a cutter to cut plastic. By adjusting the number and spacing of the cutters, the size of the shredded plastic fragments can be adjusted, thus realizing the plastic crushing function of this device. By crushing the plastic, it can make it easier to screen and process it. At the same time, the cutting size can be adjusted to control the size of the plastic fragments and meet diverse production needs. Attached Figure Description

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 5 As shown, an embodiment of this utility model provides an integrated screening device for recycling plastics, including a housing 1, and further comprising:

[0038] The feed hopper 4 is rotatably connected to the top of one side of the housing 1, and the feed hopper 4 is rotatably connected to the drive shaft 6. A drive motor 3 with the output shaft end connected to the drive shaft 6 is installed on one side of the feed hopper 4.

[0039] Cutting structure 5 is located on the outside of drive shaft 6 and is used to cut plastic.

[0040] The partition net 13 is fixed to the top inside the casing 1;

[0041] Vibrating screen 9 is set inside the casing 1, and support springs 7 connected to the casing 1 are installed on both sides of the bottom end of the vibrating screen 9. An electromagnetic vibrator 8 is installed at the bottom end of the vibrating screen 9, and a discharge port 10 is installed inside one side of the vibrating screen 9.

[0042] Screen 11 is fixed at the top inside the vibrating screen 9;

[0043] Rubber sleeve 12 is installed between vibrating screen 9 and machine casing 1;

[0044] The recycling structure 2 is disposed on both sides of the housing 1. The recycling structure 2 includes a collection box 201 fixed on both sides of the housing 1, a box cover 202 installed inside one side of the collection box 201, a fan 204 installed at the top of one side of the collection box 201, an exhaust port 205 installed at the top of the fan 204, an air duct 207 fixed at the top of the other side of the collection box 201, a filter screen 203 installed at the top of the inside of the collection box 201, a lifting component disposed at the bottom of the air duct 207, and a suction hopper 210 disposed at the bottom of the lifting component.

[0045] In this embodiment of the utility model, the plastic to be processed enters the machine casing 1 through the feed hopper 4. The drive motor 3 drives the transmission shaft 6 to rotate, causing the cutting structure 5 to crush the plastic. The cut fragments pass through the partition net 13 and fall onto the surface of the screen 11. The plastic that is not fully crushed is blocked by the partition net 13 and continues to be cut. The vibrating screen 9 is driven to vibrate at high frequency by the electromagnetic vibrator 8. At the same time, the support spring 7 assists the elastic displacement of the vibrating screen 9. The screen 11 is used to screen the plastic fragments of the appropriate size to the surface. At the same time, the recycling structure 2 collects the plastic fragments. Small impurities pass through the screen 11 and fall into the bottom of the vibrating screen 9. They are discharged through the discharge port 10. The rubber sleeve 12 seals the gap between the vibrating screen 9 and the machine casing 1 to prevent impurities from leaking out.

[0046] like Figure 4 As shown, the lifting assembly includes a folded tube 208 installed between the suction bucket 210 and the air duct 207, an electric telescopic rod 206 installed on both sides inside the housing 1, a guide frame 212 installed at the telescopic end of the electric telescopic rod 206, a slide rail 211 slidably connected to the inside of one side of the guide frame 212 and connected to the housing 1, and a fixed frame 209 fixed to one side of the guide frame 212 and connected to the suction bucket 210. The air duct 207 extends to the outside of the housing 1 and connects to the collection box 201. The suction buckets 210 are evenly distributed inside the housing 1. The folded tube 208 is a hollow tubular structure with a pleated surface and is telescopic.

[0047] In this embodiment of the invention, air discharged by the fan 204 creates a negative pressure in the collection box 201, causing the air inside the device to enter the collection box 201 through the suction bucket 210 and the air duct 207. At the same time, plastic fragments on the surface of the adsorption screen 11 enter the collection box 201 with the airflow and are intercepted by the filter screen 203. After the fan 204 stops, they fall to the bottom of the collection box 201. The electric telescopic rod 206 pushes the guide frame 212 to rise and fall along the slide rail 211, which drives the fixed frame 209 to adjust the height of the suction bucket 210. The folding tube 208 extends and retracts with the height change. When the size of the fragment to be extracted is large, the height of the suction bucket 210 is increased; when the size of the fragment to be extracted is small, the height of the suction bucket 210 is decreased, so as to achieve dynamic adsorption of fragments of different thicknesses.

[0048] like Figure 5 As shown, the cutting structure 5 includes a fixing strip 501 fixed to the outside of the drive shaft 6, a blade holder 504 installed on the top of the fixing strip 501, a cutter 503 detachably installed on one side of the blade holder 504, and a fixing bolt 502 inserted inside the cutter 503. The cutter 503 is installed on one side of the blade holder 504 by the fixing bolt 502, and the blade holders 504 are evenly distributed on the surface of the fixing strip 501.

[0049] In this embodiment of the invention, the fixed plate 501 is driven to rotate by the transmission shaft 6, and the blade holder 504 on the fixed plate 501 drives the cutter 503 to cut the plastic. In actual operation, the operator can flexibly and specifically adjust the number and spacing of the cutters 503 according to the quantity and properties of the raw materials to be screened. The size of the fragments is controlled by the spacing of the cutters 503 and the rotation speed of the transmission shaft 6, so as to cut large pieces of plastic into uniform fragments in an interlaced manner according to the needs, thereby meeting the subsequent recycling requirements.

[0050] The above description is the preferred embodiment of this 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 this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
