Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, and in particular to a plastic particle vibrating screener with good screening effect. Background Technology

[0002] Screening is a crucial step in the processing and production of plastic particles. Its main function is to effectively separate plastic particles of different sizes, thereby ensuring the smooth progress of subsequent processing and that the quality of the final product meets the standards. During the production process, plastic particles may be produced in different sizes due to various factors such as molding process, cooling rate, and cutting precision. If these particles are directly sent to subsequent processes without screening, it may lead to problems such as unstable product quality, poor molding effect, and accelerated equipment wear.

[0003] However, traditional plastic particle screening equipment largely relies on manual operation in the feeding stage. This method has many significant drawbacks. First, manual feeding is inefficient, increasing labor intensity and severely impacting production efficiency. Second, the unevenness of manual operation is one of the main reasons for poor screening results. Due to the difficulty in controlling the feeding speed and flow rate, operators may feed too much material at a time, causing plastic particles to accumulate at the inlet of the screening equipment and leading to blockages. Once a blockage occurs, it not only interrupts the screening process but also requires additional time and manpower for cleaning, further reducing production efficiency. In addition, blockages can also cause uneven stress on the screen, damaging the screen and resulting in poor screening results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a vibrating screen for plastic particles with good screening effect.

[0005] This utility model is achieved by the following technical solution: a vibrating screener for plastic particles with good screening effect, including a support plate, a screening box fixedly connected to the upper surface of the support plate, a feeding mechanism fixedly connected to the upper surface of the support plate, sleeves fixedly connected to the four corners of the bottom wall of the screening box, a telescopic spring fixedly connected to the inner wall of the sleeve, a support rod fixedly connected to the top of the telescopic spring, and a screening frame fixedly connected to the top of the support rod.

[0006] The feeding mechanism includes a support column, a positioning seat is fixedly connected to the top of the support column, a feeding cylinder is fixedly connected to the surface of the positioning seat, a motor is fixedly connected to the surface of the feeding cylinder, a discharge funnel is fixedly connected to the upper surface of the feeding cylinder, a spiral blade shaft is fixedly connected to the output end of the motor, and a discharge groove is provided on the right side of the lower surface of the feeding cylinder.

[0007] The above technical solution ensures uniform feeding of plastic particles by driving the spiral blade shaft with a motor, avoiding clogging caused by excessive flow rate in a single operation. This effectively improves the subsequent screening effect. Automated feeding avoids the tediousness and unevenness of manual operation, thus improving screening efficiency and quality.

[0008] As a further improvement to the above solution, the support column is fixedly connected to the upper surface of the support plate, and there are two positioning seats, with the feeding cylinder disposed inside one of the positioning seats.

[0009] The above technical solution, with its dual fixing structure of support column and positioning seat, enhances the stability of the feeding mechanism and avoids equipment shaking caused by vibration or external force during the feeding process.

[0010] As a further improvement to the above solution, a motor base is fixedly connected to the upper surface of the support plate, and a second motor is fixedly installed inside the motor base.

[0011] As a further improvement to the above solution, a transmission rod is fixedly connected to the output end of the second motor, and several cam blocks are fixedly connected to the surface of the transmission rod. The transmission rod is rotatably connected to the inner wall of the screening box.

[0012] Through the above technical solution, the cooperation between the cam block and the telescopic spring realizes the periodic vibration of the screening frame, ensuring that the plastic particles move fully on the surface of the screening frame, reducing screening dead angles and improving screening quality.

[0013] As a further improvement to the above solution, a guide plate is fixedly connected to the inner wall of the screening box. The guide plate is located below the discharge chute and above the screening frame.

[0014] Through the above technical solution, the design of the guide plate reduces the energy loss of plastic particles during the falling process, ensures that the plastic particles can be evenly distributed on the surface of the screening frame, and improves the screening efficiency.

[0015] As a further improvement to the above solution, a cover plate is hinged to the surface of the support plate, and a handle groove is formed on the surface of the cover plate.

[0016] As a further improvement to the above solution, a reinforcing frame is fixedly connected to the lower surface of the support plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention uses a motor to drive the spiral blade shaft to rotate, uniformly propelling plastic particles forward within the feeding cylinder and discharging them through the discharge chute. This ensures uniform particle feeding, avoids clogging caused by excessive single-flow rate, and reduces uneven screening due to material accumulation. The guide plate further optimizes the feeding process, guiding plastic particles smoothly from the discharge chute into the screening frame, preventing particles from scattering or accumulating during the fall, thus further improving screening efficiency. This automated feeding method not only improves screening effect but also avoids the tediousness and unevenness of manual operation, reduces labor intensity, and enhances the stability and reliability of equipment operation.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4This embodiment of a vibrating screener for plastic particles with good screening effect includes a support plate 1, a screening box 2 fixedly connected to the upper surface of the support plate 1, a feeding mechanism 3 fixedly connected to the upper surface of the support plate 1, sleeves 4 fixedly connected to the four corners of the bottom wall of the screening box 2, a telescopic spring 5 fixedly connected to the inner wall of the sleeve 4, a support rod 6 fixedly connected to the top of the telescopic spring 5, and a screening frame 7 fixedly connected to the top of the support rod 6.

[0028] The feeding mechanism 3 includes a support column 301, a positioning seat 302 fixedly connected to the top of the support column 301, a feeding cylinder 303 fixedly connected to the surface of the positioning seat 302, a motor 304 fixedly connected to the surface of the feeding cylinder 303, a discharge funnel 305 fixedly connected to the upper surface of the feeding cylinder 303, a spiral blade shaft 306 fixedly connected to the output end of the motor 304, and a discharge trough 307 opened on the right side of the lower surface of the feeding cylinder 303. The screening box 2 is supported by a sleeve 4, a telescopic spring 5, and a support rod 6. In the feeding mechanism 3, plastic particles enter the feeding cylinder 303 through the discharge funnel 305. The motor 304 drives the spiral blade shaft 306 to rotate, uniformly conveying the plastic particles to the discharge trough 307, where they fall into the screening box 7 for screening.

[0029] The support column 301 is fixedly connected to the upper surface of the support plate 1. There are two positioning seats 302, and the feeding cylinder 303 is disposed inside one of the positioning seats 302.

[0030] A motor base 8 is fixedly connected to the upper surface of the support plate 1, and a motor 9 is fixedly installed inside the motor base 8.

[0031] A transmission rod 10 is fixedly connected to the output end of motor 2 9. Several cam blocks 11 are fixedly connected to the surface of the transmission rod 10. The transmission rod 10 is rotatably connected to the inner wall of the screening box 2. When the cam blocks 11 rotate, their protruding parts contact the screening frame 7, lift the screening frame 7, and stretch the telescopic spring 5 through the support rod 6. When the protruding parts of the cam blocks 11 disengage from the screening frame 7, the telescopic spring 5 returns to its original position, causing the screening frame 7 to retract and vibrate, thereby realizing the periodic screening of plastic particles.

[0032] A guide plate 13 is fixedly connected to the inner wall of the screening box 2. The guide plate 13 is located below the discharge chute 307 and above the screening frame 7. The function of the guide plate 13 is to guide the plastic particles from the discharge chute 307 into the screening frame 7 smoothly, and to prevent the plastic particles from scattering or accumulating during the falling process.

[0033] A cover plate 14 is hinged to the surface of the support plate 1. A handle groove is provided on the surface of the cover plate 14. The cover plate 14 can be opened through the handle groove to easily remove the screened plastic particles.

[0034] A reinforcing frame 15 is fixedly connected to the lower surface of the support plate 1.

[0035] The implementation principle of a vibrating screen for plastic particles with good screening effect in this embodiment is as follows: First, the plastic particles to be screened need to be poured into the feeding funnel 305. The plastic particles enter the feeding cylinder 303 through the feeding funnel 305. At this time, motor 1 304 starts, driving the spiral blade shaft 306 to rotate. The rotation of the spiral blade shaft 306 causes the plastic particles to be pushed forward evenly in the feeding cylinder 303 and finally discharged through the discharge chute 307. The discharge chute 307 is located above the screening box 2. The discharged plastic particles fall smoothly into the screening frame 7 under the guidance of the guide plate 13. After the plastic particles fall into the screening frame 7, motor 2 9 starts to work, and its output end... The transmission rod 10 drives the cam block 11 to rotate. During the rotation, the protruding part of the cam block 11 periodically contacts the screening frame 7, lifting it up. At the same time, the support rod 6 stretches the telescopic spring 5. When the protruding part of the cam block 11 disengages from the screening frame 7, the telescopic spring 5 quickly resets under the action of elastic potential energy, driving the screening frame 7 to retract, thereby generating vibration. This periodic vibration causes the plastic particles on the screening frame 7 to continuously tumble and move. Small particles fall through the screen, while larger particles remain on the screening frame 7, achieving effective screening. Personnel can easily open the cover plate 14 hinged to the surface of the support plate 1 through the handle slot to remove the screened plastic particles.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
