Description

Technical Field

[0001] This utility model relates to the technical field of plastic pellet recycling and processing, specifically to a pelletizer. Background Technology

[0002] Plastic materials are recyclable. Typically, waste plastic products are recycled to resin plants or processing plants, where they are reheated, plasticized, and cooled before being cut into plastic granules for further processing into new plastic products for sale or use. After the remolded plastic strips are cut into granules, the granules need to be cleaned and dried before further processing and use.

[0003] Current technology typically involves cooling liquid plastics with cooling equipment before cutting them with plastic pellet cutting equipment. This process is relatively inefficient and takes a long time to process the plastic pellets. Utility Model Content

[0004] Therefore, it is necessary to provide a pelletizer that can solve the problem of low processing efficiency of plastic pellets.

[0005] A pelletizer includes a frame, a cooling assembly, a die assembly, a drive assembly, and a pelletizing blade assembly; The cooling assembly is mounted at one end of the frame, the drive assembly is mounted at the other end of the frame, the die head assembly is mounted on the frame and located between the cooling assembly and the drive assembly, the pelletizing blade assembly is mounted on the drive assembly, and the drive assembly drives the pelletizing blade assembly to move closer to or away from the die head assembly. The cooling assembly is used to cool liquid plastic into solid plastic.

[0006] In one embodiment, the mold head assembly includes a hydraulic lifting rod and a mold head, the bottom of which is fixedly connected to the mold head for controlling the mold head to move vertically.

[0007] In one embodiment, the die head assembly further includes a shroud mounted on the die head for cutting plastic granules within the shroud.

[0008] In one embodiment, the drive assembly includes a first motor and a lead screw, the first motor being mounted on the frame, one end of the lead screw being mounted on the first motor and the other end being mounted on the frame, and the pelletizing blade assembly being mounted on the lead screw nut.

[0009] In one embodiment, the pelletizing blade assembly includes a second motor, a drive shaft, and a pelletizing blade, with one end of the drive shaft fixedly connected to the second motor and the other end fixedly connected to the pelletizing blade.

[0010] In one embodiment, the pelletizer further includes an observation component, which includes an observation window and an observation tube. One end of the observation tube is connected to the observation window, and the other end is connected to the enclosure.

[0012] In one embodiment, the cooling assembly further includes a temperature sensor installed within the cooling assembly for detecting the temperature of the water within the cooling assembly.

[0013] The aforementioned pelletizer, through the coordinated arrangement of a cooling assembly, a die assembly, a drive assembly, and a pelletizing blade assembly, first rapidly cools the liquid plastic product through the cooling assembly to form a solid plastic product. The die assembly then processes the solid plastic product into strip-shaped plastic products, and the pelletizing blade assembly quickly cuts the strip-shaped plastic products. This integrates the cooling and pelletizing processes into one machine, improving the processing efficiency of plastic pellets and shortening the processing time. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediary component present. Conversely, when a component is said to be "directly" connected to another component, there is no intermediary component.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] like Figure 1 As shown, a pelletizer includes a frame 1, a cooling assembly, a die assembly 2, a drive assembly 3, and a pelletizing blade assembly 4; The cooling assembly is installed at one end of the frame 1, the drive assembly 3 is installed at the other end of the frame 1, the die head assembly 2 is installed on the frame 1 and is located between the cooling assembly and the drive assembly 3, the pelletizing blade assembly 4 is installed on the drive assembly 3, and the drive assembly 3 drives the pelletizing blade assembly 4 to move closer to or away from the die head assembly 2. The cooling assembly is used to cool the liquid plastic into a fixed plastic. like Figure 2 As shown, the cooling assembly contains ice water to cool the liquid plastic into a solidified plastic. The die head assembly 2 includes a hydraulic lifting rod 21 and a die head 22. The bottom of the hydraulic lifting rod 21 is fixedly connected to the die head 22 and is used to control the vertical movement of the die head 22. The hydraulic lifting rod 21 controls the vertical position of the die head 22 to match the position of the pelletizing blade 43, facilitating the cutting of the plastic strip.

[0019] The drive assembly 3 includes a first motor and a lead screw. The first motor is mounted on the frame, one end of the lead screw is mounted on the first motor, and the other end is mounted on the frame. The pelletizing knife assembly is mounted on the lead screw nut.

[0020] like Figure 3 As shown, the pelletizing blade assembly 4 includes a second motor 41, a drive shaft 42, and a pelletizing blade 43. One end of the drive shaft 42 is fixedly connected to the second motor 41, and the other end is fixedly connected to the pelletizing blade 43.

[0021] When processing plastic pellets, the liquid plastic is first placed in the ice water of the cooling component for a preset time to solidify into solid plastic. Then, the solid plastic is processed into plastic strips by the die head 22. The specific processing shape can be adjusted by the die head 22 according to actual needs. The first motor is started, driving the lead screw to rotate. The lead screw nut on the lead screw drives the pelletizing blade assembly 4 towards the die head 22 until it reaches the preset cutting position. The second motor 41 is then started, driving the transmission shaft 42 to rotate. The transmission shaft 42 drives the pelletizing blade 43 to rotate, cutting the plastic strips on the die head 22 into plastic pellets. The pellets are then recycled using the pelletizer recycling device.

[0022] In this way, the pelletizer, through the coordinated arrangement of the cooling component, die head component 2, drive component 3, and pelletizing blade component 4, first rapidly cools the liquid plastic product through the cooling component to form a solid plastic product. Then, the die head component 2 processes the solid plastic product into strip-shaped plastic products, and the pelletizing blade component 4 quickly cuts the strip-shaped plastic products. The cooling and pelletizing processes are integrated into one machine, which improves the processing efficiency of plastic pellets and shortens the processing time.

[0023] In one embodiment, the die head assembly 2 further includes a sealing cover 23, which is mounted on the die head 22 and is used for cutting plastic granules within the sealing cover 23.

[0024] In this way, the die head 22 has a mesh plate, and the plastic strip extruded by the mesh plate is contained in the closed cover 23. The closed cover 23 wraps the pelletizing knife 43 inside. The opening at one end of the closed cover 23 near the pelletizing knife 43 facilitates the cutting of the plastic strip processed by the die head 22.

[0025] like Figure 4 As shown, in one embodiment, the pelletizer further includes an observation component 5, which includes an observation window 51 and an observation tube 52. One end of the observation tube 52 is connected to the observation window 51, and the other end is connected to the enclosure 23.

[0026] In this way, by observing the configuration of component 5, it is convenient for processing personnel to observe the cutting of plastic granules through observation window 51 and observation tube 52.

[0027] In one embodiment, the pelletizer further includes an operation display screen 6, which is mounted on the frame 1 and is used to control the die assembly 2, the drive assembly 3, and the pelletizing blade assembly 4.

[0028] In this way, the operation display screen 6 is electrically connected to the control module, and the control module is electrically connected to the controllers of the die head assembly 2, the drive assembly 3, and the pelletizing knife assembly 4 respectively. By issuing commands through the operation display screen 6, the die head assembly 2, the drive assembly 3, and the pelletizing knife assembly 4 can be controlled, which is simple and fast.

[0029] In one embodiment, the cooling assembly further includes a temperature sensor installed within the cooling assembly for detecting the temperature of the water within the cooling assembly.

[0030] In this way, the temperature sensor is electrically connected to the control module to detect the temperature value of the water in the cooling component and send it to the control module. When the temperature value of the water in the cooling component reaches the preset threshold, the control module issues a control command, such as lighting up the control indicator light, to remind the operator that the liquid plastic can be placed in ice water for cooling.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
