Description

Technical Field

[0001] This utility model belongs to the field of material production equipment, specifically relating to a pelletizer for long-fiber TPU composite materials that can be cut into lengths of varying lengths. Background Technology

[0002] In the production of polymer materials, pelleting is a crucial step. Pelletizers cut molten polymer materials into particles of a specific size, facilitating subsequent processing and use. Traditional pelletizers typically use a single motor to drive both the traction and pelletizing actions of the pelletizing mechanism. While this design is simple, it has significant limitations when producing long-fiber products.

[0003] In existing technologies, traditional pelletizers use a single motor drive, and the traction speed and pelletizing speed are interrelated, resulting in a relatively fixed length of the cut long fiber products. However, in practical applications, users often require long fiber products of different lengths to meet diverse usage needs.

[0004] This invention attempts to solve or at least alleviate such defects by providing a pelletizer for long-fiber TPU composite materials that can be pelletized in various lengths. Utility Model Content

Figure 4This is a schematic diagram of the pusher part of the present invention. It can be seen that the pusher 310 is fixedly mounted on the top surface of the cutting table 340, and the pusher plate 320 is detachably mounted on the pusher 310. Figure 5 This is a schematic diagram of the screw-on machine of this utility model; Figure 6 This is a schematic diagram of the automatic tool changer of this utility model. It can be seen that the tool 530 can be mounted on the slot of the tool holder 520. Figure 7 This is a schematic diagram of the cutting tool of this utility model. It can be seen that a hanging groove 532 and an erection opening 533 are provided on the side, and the hanging groove 532 is higher than the erection opening 533.

[0018] A pelletizer for long-fiber TPU composite materials, which can be cut into various lengths, includes: a feeding section 300, which includes a cutting table 340 on the upper surface of the cutting table 340; a cutting section 100 is mounted above the feeding section 300; the feeding section 300 also includes a pushing component 310, which is mirror-displayed on the upper surface of the cutting table 340; and a push plate 320 is detachably disposed between the pushing components 310, which can push the long-fiber TPU composite material to move.

[0019] The cutting section 100 is existing technology. When the TPU composite material is placed on the upper surface of the cutting table 340, the push plate 320 can push it forward, and the cutting section 100 can cut it. At this time, the driving speed of the pushing component 310 can be adjusted according to the required length of the TPU composite material. When pushing quickly, longer fibers can be cut out, and when pushing slowly, shorter fibers can be cut out.

[0020] In a preferred embodiment of this utility model, a tool magazine 200 is fixedly disposed on the side of the cutting section 100, and an automatic tool changer 500 is fixedly disposed on one side of the cutting section 100. The automatic tool changer 500 can retrieve a tool 530 from the tool magazine 200 and deliver it to the bottom of the cutting section 100. A tool sleeve 110 is fixedly disposed at the bottom of the cutting section 100. A mounting hole 111 is provided through the side of the tool sleeve 110, and a screw hole 531 is provided through the side of the tool 530. The screw hole 531 matches the size of the mounting hole 111. A screw-on machine 400 is fixedly disposed on the front of the cutting section 100. When the automatic tool changer 500 delivers the tool 530 to the tool sleeve 110, the screw-on machine 400 can screw the bolt into the screw hole 531 and the mounting hole 111 for fixing.

[0021] When cutting long fiber reinforced materials, the wear and tear on cutting tools is significant due to the hardness of these materials. Furthermore, since most cutting tools are bolt-fixed, tool replacement is somewhat cumbersome. This invention provides a simplified tool replacement method for tool 530. The automatic tool changer 500 and tool magazine 200 are both existing technologies. The bolts are locked into the screw holes 531 and 111 using a screw-locking machine 400, thus completing the tool installation. To remove tool 530, first unscrew the bolts using the screw-locking machine 400, then remove tool 530.

[0022] As a preferred embodiment of this utility model, the automatic tool changer 500 includes a power unit 510. A tool holder 520 is detachably mounted on the bottom of the power unit 510. A notch 521 is provided on the side of the tool holder 520, and a magnetic sheet is disposed within the notch 521. A mounting opening 533 is provided on the tool 530, allowing the tool 530 to be mounted on the tool holder 520 through the mounting opening 533. Given that the automatic tool changer 500 is based on existing technology, this invention only improves the tool holder 520 by providing a notch 521 corresponding to the contour of the tool 530, placing a magnetic sheet within the notch 521, and mounting the tool 530 on the notch 521 through the mounting opening 533. This ensures that the tool 530 can be adhered to the notch 521 and not easily detached during tool transfer. When the tool 530 is transferred to fit against the tool sleeve 110, the screw-on machine 400 can be driven for installation.

[0023] In a preferred embodiment of this utility model, the tool magazine 200 has a suspension hole 210 at its bottom, the width of which is smaller than that of the tool 530. A suspension groove 532 is provided above the mounting opening 533, allowing the tool 530 to rest on the suspension hole 210 via the suspension groove 532. A drop hole 220 is provided in front of the suspension hole 210, the width of which is larger than that of the tool 530, allowing the tool 530 to fall through it. Because the suspension hole 210 is smaller than the tool 530, the tool 530 can suspend itself in the suspension hole 210 via the suspension groove 532. When the tool 530 is pushed into the drop hole 220, because the drop hole 220 is wider than the tool 530, the tool 530 can fall through the drop hole 220 and be transferred to the cutting section 100 by the automatic tool changer 500.

[0024] In a preferred embodiment of this invention, a workbench 600 is provided at the bottom of the pushing part 300, and both the cutting part 100 and the tool magazine 200 are mounted on the workbench 600. The workbench 600 elevates this invention to a suitable height for easy operation.

[0025] As a preferred embodiment of this utility model, a material box 330 is provided in front of the pusher 300, and the cut material can be stored in the material box 330.

[0026] In summary, this utility model discloses a pelletizer for long-fiber TPU composite materials that can produce pellets of varying lengths by varying the feed rate of the feeding section. Furthermore, this utility model incorporates an automatic blade changer and a blade magazine to ensure timely replacement of damaged blades. When the blade is transferred to the blade holder and aligned with the screw holes and mounting holes, a screw-on mechanism begins to screw the blade in. To remove the blade, the screw-on mechanism is used to unscrew the blade, thus achieving fully automatic blade replacement.
