[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention is provided with a movable block and a rotating roller. During the pelletizing process of the plastic strip, the plastic strip is clamped and limited by the rotating roller, so that the plastic strip will not shake or deviate during cutting, thereby avoiding the uneven cutting of the plastic particles due to the shaking of the plastic strip during cutting, thereby ensuring the production quality of the plastic particles and increasing the convenience of use of the device. After the plastic strip passes through the feed trough, the movable block moves, so that the device can select a suitable positioning groove according to the size of the plastic strip, so that the device can fix plastic strips of various specifications, which not only increases the convenience of use of the device but also increases the stability of use of the device.

[0018] The present invention is provided with a pressure sensor and a spring telescopic rod. When the rotating roller clamps the plastic strip, the spring telescopic rod squeezes the pressure sensor. Through squeezing at a preset position, the pressure sensor has an initial pressure value, and the pressure value is transmitted to the background control system for real-time monitoring. When the plastic strip is not cooled down, the inside of the plastic strip is softened. When the plastic strip is squeezed by the rotating roller, the plastic strip will deform. When the plastic strip is deformed, the squeezing force on the pressure sensor will become smaller. If the pressure value of the pressure sensor changes beyond the preset pressure value change range, it means that the plastic strip has not been cooled down. At this time, the staff is notified to immediately detect the cooling mechanism of the plastic strip to prevent the plastic strip from not being cooled down, causing the plastic particles to stick to each other after being cut, thereby ensuring the production quality of the plastic particles.

[0019] The shape of the plastic strip extruded by the extruder can also be monitored by rotating the roller to extrude the plastic strip. When the outer side of the plastic strip extruded by the extruder is irregular, the pressure value measured by the pressure sensor will fluctuate greatly when the plastic strip passes through the rotating roller. When the pressure value measured by the pressure sensor exceeds the preset pressure value change range, the background control system on the device will notify the staff to inspect the plastic strip and the extruder to ensure the production quality of the plastic particles and increase the diversity of the device's use functions.

[0020] The present invention is provided with movable plates and cleaning sponges. When plastic particles are detected to be attached to the blade, the two movable plates move to the bottom of the blade and separate. There is a gap of a preset distance between the two movable plates. Then the first electric telescopic rod drives the connecting block to extend. When the blade extends into the gap between the two movable plates, the blade is driven to rotate by the second rotating motor. At this time, the plastic particles attached to the blade will be caught by the two movable plates, and the plastic particles attached to the blade will be self-detached. Through this operation mode, the device can self-clean the plastic particles attached to the blade, which increases the convenience of use of the device and ensures the functional stability of the blade. The staff does not need to adjust the blade personally, which reduces the work intensity of the staff. At the same time, the self-adjustment mode of the device greatly reduces the downtime of the device.

[0021] After the device finishes pelletizing the plastic particles, the two movable plates move to the bottom of the blade and separate, with a gap of a preset distance between the two movable plates. The first electric telescopic rod drives the cleaning sponge to extend to a preset position, and then the blade extends between the two movable plates under the drive of the first electric telescopic rod. Then the second rotating motor drives the blade to reverse. At this time, the cleaning sponge can clean the plastic dust remaining on the blade, increasing the convenience of the device and ensuring the functional stability of the blade for the next use.

[0022] When the staff fails to transfer the plastic particles below the feeding trough in time, the plastic particles can be temporarily accumulated at the bottom end of the inner wall of the first slot above the feeding trough. At this time, the movable plate plays a role in blocking the plastic particles, and the control system on the device prompts the staff to clean the plastic particles in time. When the plastic particles are cleaned and the feeding trough can be discharged normally, the plastic particles remaining at the bottom of the first slot can be pushed into the feeding trough for discharge through the movement of the movable plate, which increases the convenience of using the device.

The third rotary motor 27 is started to drive the screw rod 29 to rotate, and the rotation of the screw rod 29 allows the displacement slider 30 to slide inside the third slot 28, thereby driving the movable block 5 to move at the spring telescopic rod 31, so that the device can select a suitable positioning slot 32 according to the size of the plastic strip.

[0045] As a technical optimization solution of the present invention, the cutting mechanism includes a connecting block 8 and a blade 22. The second connecting rod 6 is movably mounted with the connecting block 8 below the end away from the moving plate 23. The second rotating motor 21 is embedded and mounted on the side of the connecting block 8 close to the moving plate 23. The output end of the second rotating motor 21 faces the moving plate 23, and the blade 22 is mounted on the output end of the second rotating motor 21. The blade 22 rotates under the drive of the second rotating motor 21. At this time, when the plastic strip passes through the blade 22, it can be cut into plastic particles by the rotating blade 22.

[0046] As a technical optimization solution of the present invention, a first electric telescopic rod 7 is installed at the bottom of the second connecting rod 6, the telescopic end of the first electric telescopic rod 7 faces downward, and the telescopic end of the first electric telescopic rod 7 is connected to the top of the connecting block 8.

[0047] As a technical optimization solution of the present invention, a camera 19 is embedded and installed at the bottom of the second connecting rod 6, and fans 18 are installed on both sides of the second connecting rod 6. Two movable plates 9 are movably installed under the first slot 2. A second slide groove 13 is horizontally opened on the inner wall of the first slot 2 close to the movable plate 9. A second electric slider 14 is installed on the side of the movable plate 9 close to the second slide groove 13. The second electric slider 14 is slidably installed inside the second slide groove 13. When cutting plastic particles, the fan 18 is started, and the fan 18 blows downward at this time. The blow of the fan 18 can make the cut plastic particles fall directly from the feeding chute 10 under the influence of wind force, reduce the splashing of plastic particles, and increase the feeding stability of plastic particles. The camera 19 can monitor the use status of the blade 22, and the sliding of the second electric slider 14 in the second slide groove 13 can drive the movable plate 9 to move.

[0048] As a technical optimization solution of the present invention, the two movable plates 9 are provided with a second slot 16 on the side close to each other, and a cleaning sponge 15 is movably installed inside the second slot 16. A second electric telescopic rod 17 is installed on the inner wall of the second slot 16, and the telescopic end of the second electric telescopic rod 17 faces the cleaning sponge 15, and the telescopic end of the second electric telescopic rod 17 is connected to the cleaning sponge 15. When the blade 22 extends into the gap between the two movable plates 9, the blade 22 is driven to rotate by the second rotating motor 21. At this time, the plastic particles attached to the blade 22 will be stuck by the two movable plates 9, completing the self-detachment of the plastic particles attached to the blade 22. Then the blade 22 performs a reset movement, and the device continues to pelletize the plastic strips. Through this operation mode, the device completes the self-cleaning of the plastic particles attached to the blade 22, which increases the convenience of use of the device, and also ensures the functional stability of the blade 22, so that the staff does not need to adjust the blade 22 personally, reducing the staff's work intensity. At the same time, the device self-adjusts The whole method greatly reduces the downtime of the device. After the device finishes pelletizing the plastic particles, the two movable plates 9 move to the bottom of the blade 22, and the two movable plates 9 are separated. There is a gap of a preset distance between the two movable plates 9. The first electric telescopic rod 7 drives the cleaning sponge 15 to extend to a preset position, and then the blade 22 extends between the two movable plates 9 driven by the first electric telescopic rod 7. Then the second rotating motor 21 drives the blade 22 to reverse. At this time, the cleaning sponge 15 can clean the plastic dust remaining on the blade 22, which increases the convenience of use of the device and ensures the functional stability of the blade 22 when it is used next time.

[0049] When the present invention is in use, the electrical mechanisms in the device can be controlled by a preset control system outside the device. The device is used in conjunction with an existing plastic extruder. The plastic extruder is an existing mature technology, so it will not be elaborated on in detail. The plastic strips extruded by the extruder are cooled by an existing cooling device and then conveyed to the fixed cover 1 by an existing conveying device. Then the staff can install the plastic strips and the device. When in use, the fixed cover 1 is mounted on a preset fixed frame for use, and the fixed frame is provided with a plastic particle collecting mechanism under the discharge chute 10. The plastic particle collecting mechanism is an existing mature technology, so it will not be elaborated on in detail.

[0050] The plastic strip is transferred to the side of the fixed cover 1 where the first connecting rod 4 is installed, and then the plastic strip passes through the feed slot 3. When installing the plastic strip, the first electric slider 12 slides in the first slide slot 11, driving the moving plate 23 to move in the first slot 2, so that the first connecting rod 4 moves out of the first slot 2. At this time, the process of installing the plastic strip can be easier for the staff, increasing the convenience of the staff in the initial installation of the plastic strip in production.

[0051] After the plastic strip passes through the feed chute 3, the third rotary motor 27 starts to drive the screw 29 to rotate. The rotation of the screw 29 allows the displacement slider 30 to slide inside the third slot 28, thereby driving the movable block 5 to move at the spring telescopic rod 31, so that the device can select a suitable positioning slot 32 according to the size of the plastic strip, which increases the convenience and stability of the device. Subsequently, the third electric slider 26 slides in the third slide slot 25, so that the two first connecting rods 4 move closer to each other. When the two first connecting rods 4 move to the preset position, the positioning slots 32 on the two rotating rollers 24 clamp the plastic strip.

[0052] Subsequently, the plastic strip is passed through the two rotating rollers 24 through the existing transmission device, and then passes through the feed chute 3. When the end of the plastic strip is transmitted to the blade 22, the blade 22 is driven by the second rotating motor 21 to rotate. At this time, the plastic strip can be cut into plastic particles by the rotating blade 22 when passing through the blade 22. When the plastic particles are cut, the fan 18 is started, and the fan 18 blows air downward. The blow of the fan 18 can make the cut plastic particles fall directly from the feed chute 10 under the influence of wind force, thereby reducing the splashing of plastic particles and increasing the feeding stability of the plastic particles.

[0053] During the pelletizing process of the plastic strip, the plastic strip is clamped and limited by the rotating roller 24, so that the plastic strip will not shake or deviate during cutting, thereby avoiding uneven cutting of the plastic particles due to the shaking of the plastic strip during cutting, thereby ensuring the production quality of the plastic particles and increasing the convenience of use of the device;

[0054] When cutting plastic particles, the plastic strip that has not been cooled properly will not only stick to the blade 22, but also make the cut plastic particles stick together, making the plastic particles unusable. When the rotating roller 24 clamps the plastic strip, the spring telescopic rod 31 squeezes the pressure sensor 35. The device adjusts the movement of the first connecting rod 4 on the movable plate 23 according to the size of the processed plastic strip, so that the rotating roller 24 can squeeze the plastic strip, so that the pressure sensor 35 has an initial pressure value, and this pressure value is transmitted to the background control system for real-time monitoring. When the plastic strip is not cooled properly, the inside of the plastic strip is softened. At this time, when the plastic strip is squeezed by the rotating roller 24, the plastic strip will deform. When the plastic strip is deformed, the squeezing force on the pressure sensor 35 will decrease. If the pressure value of the pressure sensor 35 changes beyond the preset pressure value change range, it means that the plastic strip has not been cooled completely. At this time, the staff is notified to immediately detect the cooling mechanism of the plastic strip to prevent the plastic strip from not being cooled properly, causing the cut plastic particles to stick together, thereby ensuring the production quality of the plastic particles.

[0055] By squeezing the plastic strip by rotating the roller 24, the shape of the plastic strip extruded by the extruder can also be monitored. When the outer side of the plastic strip extruded by the extruder is irregular, when the plastic strip passes through the squeezing point of the rotating roller 24, the pressure value measured by the pressure sensor 35 will fluctuate greatly. When the pressure value measured by the pressure sensor 35 changes beyond the preset pressure value change range, the background control system on the device notifies the staff to detect the plastic strip and the extruder to ensure the production quality of the plastic particles and increase the diversity of the device's use functions.

[0056] The camera 19 monitors the cutting process of the blade 22 in real time. When it is detected that there are plastic particles attached to the blade 22, the device controls the plastic strip to stop feeding, and the second electric slider 14 slides inside the second slide groove 13, so that the two movable plates 9 move to the bottom of the blade 22, and the two movable plates 9 are separated, and there is a gap of a preset distance between the two movable plates 9. Then the first electric telescopic rod 7 drives the connecting block 8 to extend. When the blade 22 extends into the gap between the two movable plates 9, the blade 22 is driven to rotate by the second rotating motor 21. At this time, the plastic particles attached to the blade 22 will be stuck by the two movable plates 9, completing the self-detachment of the plastic particles attached to the blade 22. Then the blade 22 performs a reset movement, and the device continues to pelletize the plastic strip. Through this operation mode, the device completes the self-cleaning of the plastic particles attached to the blade 22, which increases the convenience of use of the device, and also ensures the functional stability of the blade 22, so that the staff does not need to adjust the blade 22 personally, reducing the work intensity of the staff. At the same time, the self-adjustment mode of the device greatly reduces the downtime of the device.

[0057] After the device finishes pelletizing the plastic particles, the two movable plates 9 move to the bottom of the blade 22, and the two movable plates 9 separate, with a gap of a preset distance between the two movable plates 9. The first electric telescopic rod 7 drives the cleaning sponge 15 to extend to a preset position, and then the blade 22 extends between the two movable plates 9 driven by the first electric telescopic rod 7. Then the second rotating motor 21 drives the blade 22 to reverse. At this time, the cleaning sponge 15 can clean the plastic dust remaining on the blade 22, thereby increasing the convenience of use of the device and ensuring the functional stability of the blade 22 for the next use.

[0058] During the pelletizing process of the plastic strips, most of the plastic particles will fall directly from the feed chute 10 for collection under the blowing of the fan 18, and a small number of plastic particles will splash. At this time, the movable plate 9 on one side of the first slot 2 can block the splashing plastic particles to prevent the plastic particles from directly flying out of the first slot 2, and the blocked plastic particles can be stored at the bottom end of the inner wall of the first slot 2. After the production of the plastic particles is completed, the movable plate 9 and the movable plate 23 are moved close to the feed chute 10, and the movable plate 9 and the movable plate 23 can push the plastic particles into the feed chute 10 for falling and collection, thereby increasing the convenience of using the device.

[0059] When the blade 22 needs maintenance, the movable plate 23 is moved to move the blade 22 out of the first slot 2, and then the first rotating motor 20 drives the connecting block 8 to rotate. When the blade 22 needs to be replaced, it can be directly moved to a position suitable for replacement by the staff, thereby increasing the maintenance convenience of the staff.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
