Description

Technical Field

[0001] This invention relates to the technical field of plastic pellet processing equipment, and more particularly to a modular, integrated underwater pelletizing device. Background Technology

[0002] Traditional plastic pelletizing machines work by melting and filtering plastic through an extruder, extruding it into strips, and then cutting it into pellets after cooling and solidification. Underwater pelletizing extrusion pelletizers are a new type of machine that directly cuts pellets by contacting cooling water with the molten extrusion die surface. Because the hot melt material is instantly cut off by the blades in the molten state and thrown into circulating water to cool and solidify, underwater pelletizing extrusion pelletizers are suitable for pelletizing hot melt materials of different viscosities. Compared with the traditional strip pelletizing process, the pelletizing speed is faster and the pelletizing quality is better.

[0003] After underwater pelletizing, the produced TPE granules form a solid-liquid mixture with water. The TPE granules need to be removed from the water and dried for easy storage. Current methods for transferring and drying underwater hot-cut TPE granules involve manually scooping them out, draining the water through a sieve, and then air-drying them naturally or using a blower. This method is time-consuming, labor-intensive, costly, and inefficient, and cannot meet the needs of large-scale production. Summary of the Invention

[0035] Example 1

[0036] Reference Figures 1-10 This is the first embodiment of the present invention, which provides a modular splicing integrated underwater pelletizing device, including a pelletizing body 100. In this embodiment, the pelletizing body 100 includes a receiving box 101 connected to an extruder, a pelletizing space 102 disposed in the receiving box 101, and a connection port disposed on the receiving box 101. The receiving box 101 is installed at the extrusion outlet of the extruder, and the connection port is disposed at the opening of the receiving box 101. A connection retaining ring is provided thereon, and the connection retaining ring has several bolt holes for easy installation.

[0037] Preferably, the pelletizing space 102 formed by the receiving box 101 is used to receive subsequent cutting operations and to receive moisture.

[0038] Furthermore, the present invention also includes a pelletizing assembly 200. In this embodiment, the pelletizing assembly 200 includes a pelletizing component 201 disposed in the receiving box 101, a conveying component 202 disposed at the lower end of the pelletizing component 201, and an intermittent control component 203 disposed on the pelletizing component 201. The pelletizing component 201 is used to perform pelletizing operations to cut the molten plastic extruded from the extruder. The conveying component 202 is mainly used to transport the plastic pellets outward, while the intermittent control component 203 is used to transport the cooled plastic pellets in batches. The intermittent control component 203 is connected to the conveying component 202 and controls the quantity and batch of plastic pellets entering the conveying component 202.

[0039] Furthermore, the present invention also includes a water delivery assembly 300. In this embodiment, the water delivery assembly 300 includes a water inlet pipe 301 detachably mounted on the receiving box 101, a water outlet pipe 302 mounted at the lower end of the receiving box 101, and a filter component 303 mounted inside the water outlet pipe 302. The water inlet pipe 301 is connected to a water tank, and a water pump is mounted on the water inlet pipe 301 to pump water from the water tank into the receiving box 101, thereby filling the pelletizing space 102 with cooling water. The water outlet pipe 302 is used to discharge the cooling water outward, thereby keeping the water in a circulating state, continuously absorbing the heat of the molten plastic particles and cooling them.

[0040] Furthermore, in this embodiment, the pelletizing component 201 includes a sealing box 201a disposed within the receiving box 101, a cutting block 201b disposed on the sealing box 201a, a plurality of cutting blades 201c disposed on the cutting block 201b, and an elastic member 201d disposed within the sealing box 201a and abutting against the cutting block 201b. The sealing box 201a is detachably connected to the receiving box 101, and the cutting block 201b is disposed on the side wall of the sealing box 201a. In order to make the cutting block 201b closer to the extrusion port of the extruder, the cutting block 201b and the sealing box 201a are connected by a rotating shaft, and the cutting blades 201c are disposed around the cutting block 201b and positioned below the extrusion port.

[0041] Preferably, a connecting rod extends from the sealed housing 201a, and a plate is formed at the end of the rod near the inner wall of the receiving housing 101. Bolts are provided on the plate for connection.

[0042] Preferably, a rotating shaft is provided on the cutting block 201b, and a bushing is provided on the rotating shaft. The bushing is connected to the rotating shaft. This arrangement allows the cutting block 201b to be detachably connected to the rotating shaft, which facilitates the operator to replace the cutting block 201b later.

[0043] Preferably, a liquid guide plate 201e is provided on the cutting blade body 201c. The liquid guide plate 201e is bent. In this embodiment, the cutting blade body 201c includes a main blade body and a cutting blade body fixedly connected to the main blade body. The overall shape of the cutting blade body is a semi-elliptical plate. The liquid guide plate 201e is provided on the main blade body. The overall shape of the liquid guide plate 201e is arc-shaped and extends outward from the main blade body. The arc-shaped opening of the liquid guide plate 201e faces the direction of the cutting blade body. When the cutting blade body 201c rotates, the cutting blade body part cuts, and at the same time, the liquid guide plate 201e will move the water as the cutting blade body 201c rotates, so that the water flows towards the direction of the extrusion port.

[0044] Furthermore, in this embodiment, the conveying component 202 includes a bracket 202a disposed in the receiving box 101, a conveying guide roller 202b slidably connected to the bracket 202a, a conveying pressure plate 202c disposed at the lower end of the conveying guide roller 202b, a water passage hole 202d opened on the conveying pressure plate 202c, and a filter pipe 202e disposed at the lower end of the receiving box 101 and connected to the water output pipe 302. The bracket 202a is detachably connected to the receiving box 101 by bolts.

[0045] In this embodiment, two supports 202a are provided, each with a cylindrical ring. The cylindrical rings of the two supports 202a correspond to each other, and the conveying guide roller 202b passes through the two cylindrical rings. The cylindrical rings limit the position of the conveying guide roller 202b to ensure that the conveying guide roller 202b remains vertical. The conveying pressure plate 202c is fixed to the lower end of the conveying guide roller 202b by bolts. The conveying pressure plate 202c is disc-shaped, and water passage holes 202d are evenly opened on the conveying pressure plate 202c. The size of each water passage hole 202d is smaller than the extrusion nozzle size of the extruder. Therefore, when the conveying pressure plate 202c is pressed down, a number of bottomed particles are forced into the filter pipe 202e along with the cooling water. As the conveying pressure plate 202c is gradually pressed down, the cooling water between the conveying pressure plate 202c and the filter pipe 202e is discharged from the water passage holes 202d.

[0046] Preferably, the water passage hole 202d penetrates the conveying pressure plate 202c. Rubber baffles are installed in the openings at the upper and lower ends of the water passage hole 202d. A cross opening is opened on the rubber baffle. The inner diameter of the upper half of the water passage hole 202d is smaller than that of the lower half. When the conveying pressure plate 202c moves down, the water will pass through the cross opening and enter the water passage hole 202d, and flow out from the upper opening. When the conveying pressure plate 202c is stationary, the water can no longer enter the water passage hole 202d.

[0047] Furthermore, a lever 202f is hinged to the upper protruding end of the conveying guide roller 202b. The lever 202f is connected to the intermittent control component 203. Several gripping members are provided on the conveying pressure plate 202c. In this embodiment, the gripping members include a ring provided on the conveying pressure plate 202c. The ring facilitates the formation of a surrounding space when the conveying pressure plate 202c is pressed down, making it easier to press down and grip the plastic particles. At the same time, several petals are provided at the lower end of the ring, and the petals are arranged around it.

[0048] Preferably, a telescopic spring 202g is provided between the conveying guide roller 202b and the bracket 202a to drive the conveying guide roller 202b to move upward. One end of the telescopic spring 202g is connected to the conveying guide roller 202b and the other end is connected to the bracket 202a. After the conveying guide roller 202b moves downward, when the upper lever 202f no longer applies downward pressure, the telescopic spring 202g pulls the conveying guide roller 202b upward.

[0049] Furthermore, in this embodiment, the intermittent control component 203 includes a first rotating disk 203a disposed in the sealed housing 201a, a ratchet 203b disposed on the first rotating disk 203a, a ratchet 203c disposed in the sealed housing 201a and meshing with the ratchet 203b, a dial 203d coaxially disposed with the cutting block 201b, and an extension rod 203e disposed on the dial 203d. The first rotating disk 203a is fixed to the inner wall of the sealed housing 201a, and the ratchet 203b is fixedly connected to the first rotating disk 203a. Meanwhile, a rotation center is provided at one end of the ratchet 203c, so that the ratchet 203c rotates at a certain angle. A torsion spring is also provided on the ratchet 203c, which will keep the ratchet 203c always meshing with the ratchet 203b.

[0050] Preferably, both the actuating disk 203d and the first rotating disk 203a are arranged in a vertical direction, and the actuating disk 203d is connected to the rotating shaft 307, so that the rotation of the actuating disk 203d is synchronized with the cutting block 201b, while the extension rod 203e extends along the radial direction of the actuating disk 203d.

[0051] Furthermore, a chuck 203f rotates on the first rotating disk 203a, and a mating contact 204 extends from the chuck 203f along the radial direction of the chuck 203f. A locking lever 205 is provided on the mating contact 204, and the locking lever 205 is perpendicular to the surface of the mating contact 204. A hinge joint 206 is provided on the mating contact 204 and is hinged to the upper end of the lever 202f. The hinge joint 206 also extends along the vertical direction of the surface of the mating contact 204. The rotation center of the ratchet 203c is also located on the mating contact 204. When the actuating disk 203d rotates, it will contact the locking lever 205, and with the actuation of the locking lever 205, the locking lever 205 moves together, thereby causing the chuck 203f to rotate together, which in turn drives the ratchet 203c to move together.

[0052] Preferably, a driving component for rotating the actuating disk 203d is provided outside the sealed housing 201a. In this embodiment, the driving component includes a motor housing provided outside the sealed housing 201a, a motor is provided inside the motor housing, a first driving gear is provided on the motor shaft of the motor, and a second driving gear is provided on the rotating shaft 307 that meshes with the first driving gear. When the motor starts, it drives the first driving gear to rotate, and the first driving gear drives the second driving gear to rotate by meshing with the second driving gear, thereby further driving the rotation of the rotating shaft 307.

[0053] Furthermore, a receiving cylinder 304 is formed at the upper end of the water output pipe 302, and a baffle 305 is provided at the lower end of the filter pipe 202e. The filter pipe 202e is slidably connected to the water output pipe 302. In this embodiment, the filter component 303 includes a particle outlet 303a provided at the lower end of the filter pipe 202e, a plurality of first rotating rods 303b rotatably connected to the baffle 305, and a plurality of second rotating rods 303c hinged to the lower side of the receiving cylinder 304. 3b is hinged to the second rotating rod 303c. A hinge block 303d is provided at the hinge point between each second rotating rod 303c and the first rotating rod 303b. A closing plate 303e is provided on each hinge block 303d. A plurality of first rotating rods 303b are arranged in a circular array along the particle outlet 303a. A plurality of second rotating rods 303c are arranged corresponding to a plurality of first rotating rods 303b. A spring 306 is provided between the first rotating rods 303b and the second rotating rods 303c.

[0054] Furthermore, the closing plate 303e is rotatably connected to the hinge block 303d. A rotating block extends from the closing plate 303e and is rotatably connected to the hinge block 303d. A pull bar 308 is hinged to the rotating block. There are two pull bars 308, which are respectively connected to the first rotating rod 303b and the second rotating rod 303c. The straight line direction between the connection positions of the two pull bars 308 is the diameter direction of the rotating block. The hinge point between the two pull bars 308 and the rotating block is located near the side wall of the rotating block.

[0055] Furthermore, a discharge component 400 is provided at the lower end of the receiving box 101. In this embodiment, the discharge component 400 includes a receiving funnel 401 provided at the lower end of the water output pipe 302, a receiving tray 402 provided at the lower end of the receiving funnel 401, a distributing tray 403 rotatably connected inside the receiving tray 402, a plurality of distributing grooves 404 are provided on the distributing tray 403, the distributing grooves 404 are provided along the circular array of the distributing tray 403, the end of the distributing tray 403 abuts against the inner wall of the receiving tray 402, and a discharge port 405 is provided at the lower end of the receiving tray 402.

[0056] After the plastic granules fall into the receiving funnel 401, they will fall into the distributing trough 404 and be held by it. The distributing trough 404 will rotate them together. When the distributing plate 403 moves the plastic granules, the plastic granules are rubbed between the distributing trough 404 and the receiving plate 402, thereby correcting the shape of the plastic granules.

[0057] Furthermore, a protruding block is provided on the side wall of the conveying pressure plate 202c, and a connecting plate is provided on the inner wall of the filter pipe 202e to abut against the protruding block. The protruding block allows the conveying pressure plate 202c to contact and squeeze the connecting plate when it is pressed down, so that the downward movement of the conveying pressure plate 202c will drive the filter pipe 202e to move down together.

[0058] Preferably, a telescopic rod 406 is provided at the upper end of the conveying pressure plate 202c, and an adjusting cylinder is provided at the upper end of the telescopic rod 406. The telescopic rod 406 is used to finely adjust the length of the conveying pressure plate 202c extending downward.

[0059] Operation process: Install the receiving box 101 into the extrusion outlet of the extruder through the bolt holes on the connecting retaining ring and bolts. At the same time, install the water inlet pipe 301 of the water conveying assembly 300 onto the receiving box 101. Connect the water inlet pipe 301 to the water tank and install the water pump. Connect the water outlet pipe 302 to the lower end of the receiving box 101.

[0060] Then, the water pump of the water delivery assembly 300 is started to pump water from the water tank into the receiving box 101, filling the pelletizing space 102 with cooling water. The motor of the pelletizing assembly 200 drive unit is started, and the motor shaft drives the first drive gear to rotate. Through meshing with the second drive gear, the rotating shaft 307 is rotated, causing the cutting block 201b to rotate. The cutting blade 201c, which is set on the cutting block 201b, cuts the molten plastic extruded by the extruder below the extrusion port.

[0061] When the cutting block 201b rotates, the actuating disk 203d, which is coaxially mounted with it, rotates synchronously. The extension rod 203e on the actuating disk 203d contacts the locking rod 205 on the chuck 203f in the intermittent control component 203, and drives the locking rod 205 to move, causing the chuck 203f to rotate, which in turn drives the ratchet 203c on the mating contact 204 to move together. During the rotation of the chuck 203f, the hinge joint 206 on the mating contact 204 drives the lever 202f, which is hinged to it, to move. The lever 202f pushes the conveying guide roller 202b downward. The conveying guide roller 202b moves vertically downward under the limit of the cylindrical ring of the bracket 202a, compressing the telescopic spring 202g between it and the bracket 202a, and the lower conveying pressure plate 202c descends accordingly.

[0062] As the conveying plate 202c descends, it pushes the sunken plastic granules to the bottom and uses the protruding block to contact the connecting plate on the inner wall of the filter pipe 202e, causing the filter pipe 202e to move downwards together. At this time, the conveying plate 202c presses the sunken granules along with cooling water into the filter pipe 202e. As the conveying plate 202c gradually presses down, the cooling water between the conveying plate 202c and the filter pipe 202e is discharged from the water passage hole 202d on the conveying plate 202c.

[0063] As the conveying plate 202c gradually approaches the filter pipe 202e, the first rotating rod 303b and the second rotating rod 303c change from being far apart to being close together. At this time, several closing plates 303e will approach each other and seal the lower end of the filter pipe 202e. At this time, the plastic particles are completely pressed under the conveying plate 202c, and the water is guided to the position above the conveying plate 202c.

[0064] When the actuating disc 203d continues to rotate the lever 205, and the lever 205 moves to the position below the ratchet 203b, the direction of the teeth of the ratchet 203b changes from upward to downward. Consequently, the upward force applied by the spring 306 to the lower end of the lever 202f will directly act on the chuck 203f. At this time, the engagement between the ratchet 203c on the chuck 203f and the ratchet 203b is no longer blocked. The lever 202f will rise rapidly, thereby driving the chuck 203f to rotate rapidly. During this process, the conveying plate 202c is also pulled up rapidly in sync, and the conveying plate 202c drives the filter pipe 202e to move upward in sync.

[0065] At this time, the first rotating rod 303b and the second rotating rod 303c are each pulled and change to a state of moving away from each other. The first rotating rod 303b and the second rotating rod 303c moving away from each other will pull the pull bar 308. The pull bar 308 will drive the rotating block, so that the closing plate 303e will rotate from the original horizontal state to the vertical state. At this time, the lower channel of the filter pipe 202e opens, and the plastic particles fall and are exposed from the lower water output pipe 302.

[0066] Then, the plastic granules fall from the receiving funnel 401 into the distributing groove 404 of the distributing tray 403 inside the receiving tray 402. The distributing tray 403 rotates, and the distributing groove 404 clamps the plastic granules and moves together. The plastic granules are rubbed between the distributing groove 404 and the receiving tray 402 to correct their shape, and finally discharged from the discharge port 405 at the lower end of the receiving tray 402.

[0067] The entire operation process allows the granules to be fully cooled in the water after being cut, and solid-liquid separation is achieved during the outward conveying process, separating the plastic granules from the water. This eliminates the need for subsequent filtration, reducing processing steps. Furthermore, the downward pressing process of the conveying plate 202c is relatively slow, thus filtering out as much water as possible and allowing more water to be discharged from the space between the conveying plate 202c and the filter pipe 202e. Meanwhile, the upward movement speed of the conveying plate 202c is relatively fast, which allows the plastic granules between the conveying plate 202c and the filter pipe 202e to fall quickly. This structure achieves rapid solid-liquid separation and increases production efficiency.

[0068] The entire device is integrated within the receiving housing 101, and each internal component can be disassembled, achieving modular installation and facilitating subsequent maintenance.
