Description

Technical Field

[0001] This utility model relates to the field of plastic pelletizing, specifically to a multi-angle adjustable plastic pelletizer. Background Technology

[0002] A plastic pelletizer is a mechanical device specifically designed to cut plastic raw materials (such as waste plastic products, extruded strips, or molten plastic) into uniform pellets. It mainly serves the plastic recycling and processing industry. When dealing with materials of different properties, the original cutting angle is no longer suitable, and it is necessary to adjust the angle between the blade and the pelletizing disc.

[0003] For example, the authorized utility model patent with application number 202421103031.5 discloses an anti-adhesion cutting device for a plastic granulator, including a granulator body, a fixed shell on the surface of the granulator body, a motor on the surface of the fixed shell, the output end of the motor extending into the interior of the fixed shell and provided with a clamping mechanism, a fixed block at one end of the clamping mechanism, a transmission rod connected to the inner wall of the fixed block, an adjustment mechanism at one end of the transmission rod, a first bevel gear fixedly sleeved at the other end of the transmission rod, a second bevel gear meshing on the surface of the first bevel gear, a first rotating shaft fixedly sleeved at the axis of the second bevel gear, and the first rotating shaft rotatably sleeved with the fixed block.

[0004] However, the blade angle adjustment range is limited, and the blade holder may come into contact with the pelletizing disc within a certain range. Under high-speed rotation, the blade holder and the pelletizing disc will wear against each other, resulting in uneven pelleting or performance degradation. In addition, the cooling effect of a single fan is limited, and after long-term operation, the blade and plastic particles are prone to sticking together, reducing the pelleting effect and service life of the blade.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Detailed Implementation

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, a multi-angle adjustable plastic pelletizer is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8 As shown, the multi-angle adjustable plastic pelletizer according to an embodiment of the present invention includes: an extruder body 1; a pelletizing chamber 2, disposed at one end of the extruder body 1; a control panel 3, disposed on one side of the pelletizing chamber 2; an observation window 4, disposed on the other side of the pelletizing chamber 2; a discharge port 5, disposed at the bottom of the pelletizing chamber 2; a pelletizing mechanism 6, disposed inside the pelletizing chamber 2, for realizing multi-angle pelletizing of plastic; and a heat dissipation mechanism 7, disposed outside the pelletizing mechanism 6 and fixedly connected to one end inside the pelletizing chamber 2, for realizing comprehensive cooling of the plastic pellets and blades.

[0026] With the help of the above-mentioned technical solution of this utility model, the angle adjustment of the blade 6044 is more flexible and safer through the pelletizing mechanism 6, which does not require manual adjustment, improves the continuity of production, and also effectively avoids component wear, ensuring the stable operation and safety of the pelletizing mechanism 6. Through the heat dissipation mechanism 7, the fan 7032 and the annular shell 701 form an annular air guide structure to form a closed cooling airflow path, which uniformly dissipates heat to the cutting area of ​​plastic particles, reduces the temperature rise of the blade 6044 and the pelletizing chamber 2, extends the service life of the blade 6044, and improves pelletizing stability and pellet forming quality.

[0027] It should be noted that the extruder body 1 consists of a screw, a barrel, a feeding device, a heating device, etc. The barrel and the screw cooperate to form a closed cavity. The raw material is injected into the cavity through the feeding device. Then, the heated raw material moves in the barrel through the screw, and pressure is applied to the raw material to make it uniformly mixed. Finally, it is extruded and shaped through the granulation disc 601. This is the prior art and will not be described in detail here.

[0028] In addition, the first motor 6022, the electric telescopic rod 6023, and the second motor 7033 are electrically connected to the control panel 3. The start command is issued through the human-machine interface (HMI) of the control panel 3. The signal is transmitted from the HMI to the PLC programmable logic controller. After receiving the command, the PLC controls the start, stop, rotation, and power of the above-mentioned components, thereby precisely controlling the rotation angle of the blade 6044 and the extension distance of the electric telescopic rod 6023. This is prior art and will not be elaborated on further here.

A driving member 602 is disposed at the other end of the pelletizing chamber 2, and an adjusting member 603 that cooperates with the pelletizing disc 601 is disposed at one end of the driving member 602. The driving component 602 includes a U-shaped fixing plate 6021 disposed at one end of the pelletizing chamber 2. A first motor 6022 is disposed inside the U-shaped fixing plate 6021. Electric telescopic rods 6023 are symmetrically disposed on both sides of the U-shaped fixing plate 6021. A limiting groove 6024 is formed on the outer side of the output shaft of the first motor 6022. A rotating sleeve 6025 is sleeved on the outer side of the output shaft of the first motor 6022. A limiting block 6026 that cooperates with the limiting groove 6024 is disposed inside the rotating sleeve 6025. A connecting plate 6027 that cooperates with the electric telescopic rod 6023 is disposed on the outer side of the rotating sleeve 6025. A bearing is disposed between the connecting plate 6027 and the rotating sleeve 6025. The adjusting component 603 includes a rotating shaft 6031 fixedly connected to one end of the rotating sleeve 6025. The rotating shaft 6031 is hollow, and a first fixing plate 6032 and a second fixing plate 6033 are sequentially arranged inside the rotating shaft 6031. A triangular support block 6034 is provided through the second fixing plate 6033 at one end of the rotating shaft 6031. A third fixing plate 6035 is vertically arranged at the end of the first fixing plate 6032 away from the second fixing plate 6033. A connecting roller 6036 is inserted at the end of the first fixing plate 6032 near the third fixing plate 6035. A first bevel gear 6037 is provided at one end of the connecting roller 6036, and a first bevel gear 6037 is provided on the outer side of the first bevel gear 6037 to mesh with it. A second bevel gear 6038 has a control lever 6039 at one end near the third fixed plate 6035, which passes through the third fixed plate 6035 and the rotating shaft 6031. A sun gear 60310 is provided at the other end of the connecting roller 6036. Several planetary gears 60311 are provided on the outside of the sun gear 60310, and a worm gear 60312 is provided in the middle of each of the planetary gears 60311. The worm gear 60312 is connected to the first fixed plate 6032 and the second fixed plate 6033. Worm wheels 60313 are provided on the outside of the worm gear 60312 and on the side of the triangular support block 6034. A blade 604 is provided in the middle of the worm wheel 60313, which passes through the side wall of the rotating shaft 6031. The blade assembly 604 includes a rotating roller 6041 disposed in the middle of the worm gear 60313. A fixed disk 6042 is disposed at the top of the rotating roller 6041, and a cutting bar 6043 is disposed at the top of the fixed disk 6042. A blade 6044 is disposed on the outer side of the cutting bar 6043. The blade 6044 includes a vertical section 6045 disposed on the outer side of the cutting bar 6043. A cutting section 6046 is symmetrically arranged at the top and bottom of the vertical section 6045, and several ventilation holes 6047 are opened on both sides of the vertical section 6045 to realize multi-angle adjustment of the blade 6044.

[0030] The working principle of the driving component 602 and the adjusting component 603 is as follows: The operator sends a start command to the first motor 6022 through the control panel 3. The output shaft of the first motor 6022, upon receiving the start command, drives the rotating sleeve 6025 to rotate under the cooperation of the limiting groove 6024 and the limiting block 6026. At this time, the connecting plate 6027 on the outside of the rotating sleeve 6025 remains stationary under the action of the bearing. When the rotating sleeve 6025 stops and it is necessary to change its axial distance, the operator sends a start command to the electric telescopic rod 6023 through the control panel 3. The electric telescopic rod 6023, upon receiving the start command, drives the connecting plate 6027 to reciprocate. At this time, the rotating sleeve 6025 inside the connecting plate 6027 reciprocates on the output shaft of the first motor 6022.

[0031] When the rotating sleeve 6025 reciprocates or rotates, the rotating shaft 6031 fixedly connected to it in the adjusting component 603 is simultaneously driven to move accordingly, thus moving closer to and away from the granulation disc 601. When pelletizing is required and the angle between the blade 6044 and the granulation disc 601 needs to be adjusted, the operator stops the operation of the device and rotates the control lever 6039 using a wrench or other tools. The rotating control lever 6039 drives the second bevel gear 6038 to rotate. At this time, the first bevel gear 6037 meshing with it is synchronously driven to rotate, and the rotating first bevel gear 6037 drives the connecting roller 6036 to rotate. At the same time, the sun gear 60310 at the other end of the connecting roller 6036 also rotates, and several planetary gears 60311 meshing with it are synchronously driven to rotate. The rotating planetary gears 60311 drive the worm gear 60312 to rotate, and the rotating worm gear 60312 drives the worm wheel 60313 to rotate. The rotating worm wheel 60313 drives the blade 604 to rotate radially.

[0032] The working principle of the blade 604 and the adjusting component 603 is as follows: the rotation of the worm gear 60313 drives the rotating roller 6041 to rotate, which in turn drives the fixed disk 6042 and the blade bar 6043 to rotate. Under the rotation of the blade bar 6043, the blade 6044 rotates in the corresponding direction, thereby changing the angle between the cutting section 6046 at both ends of the vertical section 6045 and the granulation disk 601. Under the action of the ventilation port 6047, the air pressure generated during the rotation passes through the ventilation port 6047, preventing damage to the blade 6044.

[0033] In one embodiment, the heat dissipation mechanism 7 includes an annular shell 701 disposed inside the pelletizing chamber 2. An air inlet 702 is provided on the side of the annular shell 701, penetrating the side wall of the pelletizing chamber 2. A blower 703 cooperating with the air inlet 702 is provided on one side of the pelletizing chamber 2. A first partition 7011, a second partition 7012, and a third partition 7013 are sequentially disposed inside the annular shell 701. A first baffle 7014 connected to the second partition 7012 is disposed inside the first partition 7011 near the air inlet 702. An air outlet 7015 is provided at one end of the second partition 7012 near the first baffle 7014. A second baffle 7016 connected to the second partition 7012 is disposed on the side of the third partition 7013 near the air outlet 7015. Several air outlets 7017 are provided on the side of the third partition 7013. An air inlet cavity 7018 is formed between the first partition 7011 and the second partition 7012, and an air outlet cavity 7019 is formed between the second partition 7012 and the third partition 7013. The inner diameter of the air inlet cavity 7018 gradually decreases in the direction away from the air inlet 702, and gradually increases in the direction near the air outlet 7015. The blower 703 includes a fan housing 7031 disposed on one side of the pelletizing cavity 2, a fan 7032 disposed inside the fan housing 7031, a second motor 7033 connected to the fan 7032 disposed on one side of the fan housing 7031, and several air inlet holes 7034 are opened on the surface of the fan housing 7031 to achieve all-round cooling of the blade 6044 and the plastic particles.

[0034] It should be noted that a filter is installed inside the fan housing 7031 to prevent dust and impurities from entering.

[0035] The working principle of the heat dissipation mechanism 7 is as follows: First, the operator starts the second motor 7033 through the control panel 3. The output shaft of the second motor 7033, which receives the start command, drives the fan 7032 to rotate and continuously generate airflow. The airflow generated by the fan 7032 enters the air inlet cavity 7018 through the air inlet 702. Under the obstruction of the first baffle plate 7014, the airflow can only move in one direction. When the airflow is in front of the narrow part of the air inlet cavity 7018, it gradually accelerates under the action of the venturi tube. When it moves to the narrow part, the airflow speed is the maximum and the pressure is the lowest. When it moves to the air outlet 7015, the accelerated airflow flows into the air outlet cavity 7019 under the action of the first baffle plate 7014. Under the action of the second baffle plate 7016, the accelerated airflow moves in one direction in the air outlet cavity and blows towards the blade 6044 and the granulation disc 601 through the air outlet 7017.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In practical applications, First, before pelletizing, the operator starts the drive unit 602 in the pelletizing mechanism 6 through the control panel 3, which drives the blade 6044 in the adjusting unit 603 to gradually approach the pelleting disc 601 (the working principle of the drive unit 602 and the adjusting unit 603 is as described above). After the drive is completed, the operator opens the observation window 4 and manually adjusts the angle between the blade 6044 and the pelleting disc 601 according to the properties of the material (the working principle of the blade 6044 and the adjusting unit 603 is as described above). After the adjustment is completed, the observation window 4 is closed. When the extruder body 1 is operating, the plastic is extruded and shaped through the holes of the granulation disc 601. At this time, the output shaft of the first motor 6022 drives the blade 6044 to rotate. At the same time, the operator starts the second motor 7033 through the control panel 3, which drives the fan 7032 to continuously generate airflow. Under the action of the first partition 7011, the second partition 7012 and the third partition 7013 in the annular shell 701, an annular airflow is formed, which cools the rotating blade and the granulated plastic in all aspects. (The working principle of the heat dissipation mechanism 7 is as described above.) The granulated plastic particles are collected uniformly through the discharge port 5. During operation, the operator observes the operation in the granulation chamber 2 in real time through the observation window 4.

[0038] In summary, with the help of the above-mentioned technical solution of this utility model, the angle adjustment of the blade 6044 is more flexible and safer through the pelletizing mechanism 6, while also effectively avoiding component wear and ensuring the stable operation and safety of the pelletizing mechanism 6. Through the heat dissipation mechanism 7, the fan 7032 and the annular shell 701 form an annular air guide structure to constitute a closed cooling airflow path, which uniformly dissipates heat to the cutting area of ​​the plastic particles, reduces the temperature rise of the blade 6044 and the pelletizing chamber 2, extends the service life of the blade 6044, and improves the pelletizing stability and the quality of the plastic particles.
