Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, specifically to an automatic pelletizer. Background Technology

[0002] Pelletizers are generally the last step in an extrusion production line. They are mainly used to process modified plastics by cutting the plastic strips that have been extruded from the extruder and cooled in a water tank into uniformly sized particles, which facilitates subsequent injection molding processes. They are used in automotive parts, household plastic parts, and daily necessities.

[0003] Existing automatic pelletizers often guide the feed strips into the cutting area using simple guide plates or manual intervention. When particle length fluctuations or flattening occur, uneven spacing between the feed strips can easily lead to deviations in pellet size, severely affecting subsequent processing quality. For example, when multiple feed strips are conveyed in parallel, inconsistent spacing can easily result in undesirable cutting effects such as pellet sticking, flattened pellets, and uneven cuts. Generally, the required particle shape is uniform in size and cylindrical with neat cuts, which may necessitate frequent machine stops for adjustments. Therefore, improvements are necessary.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0022] Example 1:

[0023] An automatic pelletizer includes a base 1, a pelletizer body 2 on the upper end of the base 1, a mounting seat 3 on the upper end of the pelletizer body 2, a blade box 4 and a drive assembly 7 for driving the cutters inside the blade box 4 on the mounting seat 3, a large electrical box 5 and a small electrical box 6 on one side of the pelletizer body 2, a feed inlet 11 on one side of the pelletizer body 2, support plates 12 on both sides of the feed inlet 11, and a traction roller 13 between the two support plates 12 for arranging material strips at intervals and pulling them into the pelletizer body. The surface of the traction roller 13 is provided with an annular limiting groove with a groove depth of 3mm and the spacing is adapted according to the diameter of the material strip to ensure that the material strips are embedded in the groove one by one to avoid misalignment. The traction roller 13 can be driven to rotate by an external power source.

[0024] In use, the material strips enter through the feed inlet 11 and are pulled into the pelletizer body 2 by the gaps between the traction rollers 13 between the support plates 12. The drive assembly 7 drives the cutter in the cutter box 4 to cut the material strips. The large electrical box 5 and the small electrical box 6 provide power and control support. The traction rollers 13 solve the problem of uneven spacing of material strips in the prior art, avoid overlapping or missing cuts during cutting, reduce particle length fluctuations and flattening, reduce the frequency of machine downtime for adjustment, and improve the quality of subsequent processing.

[0025] In this embodiment, the drive assembly 7 includes a drive motor 71. The output end of the drive motor 71 is connected to the tool box 4 via a coupling and a rotating shaft. The coupling is covered by a coupling cover 72, which is made of ABS plastic with a thickness of 8-10mm. The tool box 4 is provided with a gear cover 8, which is made of cold-rolled steel plate with a thickness of 5mm. When the drive motor 71 is running, it transmits power to the cutter inside the tool box 4 through the coupling and the rotating shaft, driving the cutter to rotate and achieve cutting. The coupling cover 72 and the gear cover 8 respectively cover the external transmission components of the coupling and the tool box 4, preventing the operator from contacting the rotating components, while also preventing dust and impurities from entering the transmission structure, improving safety and extending the equipment life.

[0026] It should be noted that during operation inside the pelletizer body, conventional techniques known to those skilled in the art are employed. For example, the pellets, after being spaced by the traction roller 13, enter the cutting area through the feed inlet 11 of the pelletizer body. The drive assembly 7 transmits power to the cutting mechanism inside the cutter box 4, which includes a moving blade (rotating blade) and a fixed blade (fixed blade). The moving blade is fixed to the cutter shaft via a key connection, and the fixed blade is fixed to the inner wall of the cutter box 4 via bolts, forming a cutting gap of 0.1-0.3mm with the moving blade. When the front end of the pellet contacts the blade of the fixed blade, the high-speed rotating moving blade cooperates with the fixed blade to cut the pellet into pellets. The cut pellets are discharged through the discharge port at the bottom of the cutter box 4. An inclined guide plate is provided below the discharge port to guide the pellets into the subsequent conveying device.

[0027] In this embodiment, a top cover 9 is hinged to the upper end of the gear cover 8, and a pneumatic support rod 10 is provided on the side of the gear cover 8. The output end of the pneumatic support rod 10 is connected to the side of the top cover 9. When it is necessary to maintain the internal components of the tool box 4, the top cover 9 is opened, and the pneumatic support rod 10 extends and supports the top cover 9 to keep it open. The opening angle of the top cover 9 can reach 55°, and the sealing gap between the top cover 9 and the gear cover 8 when closed is ≤0.5mm, which takes into account both maintenance convenience and dust prevention. After maintenance, the pneumatic support rod 10 retracts to assist the top cover 9 in closing. The hinged design of the top cover 9 makes it easy to open, and the pneumatic support rod 10 can fix the top cover 9 without manual support, which improves the convenience of maintenance operations, saves manpower, and improves maintenance efficiency.

[0028] In this embodiment, the surface of the small electrical box 6 is equipped with a digital display 14, a speed control switch 15, an emergency stop button 16, a start switch 17, and a stop switch 18. The start switch 17 and the stop switch 18 control the start and stop of the equipment. The speed control switch 15 adjusts the speed of the drive motor 71, thereby adjusting the cutting speed. The digital display 14 displays the equipment operating parameters in real time. In an emergency, pressing the emergency stop button 16 can quickly cut off the power and stop the equipment. This technology is common in the market and is known to those skilled in the art, so it will not be described in detail here.

[0029] In this embodiment, the lower end of the base 1 is provided with casters 19. The casters 19 can roll. When the equipment is pushed, the casters 19 rotate, realizing the overall movement of the equipment. This facilitates the transfer or adjustment of the equipment between different work sites, improves the flexibility of the equipment, and saves manpower for handling.

[0030] The working principle of this utility model is as follows: The automatic pelletizer includes a base 1, a pelletizer body 2 on the upper end of the base 1, a mounting seat 3 on the upper end of the pelletizer body 2, a blade box 4 and a drive assembly 7 for driving the cutters inside the blade box 4 on the mounting seat 3, a large electrical box 5 and a small electrical box 6 on one side of the pelletizer body 2, a feed inlet 11 on one side of the pelletizer body 2, support plates 12 on both sides of the feed inlet 11, and a traction roller 13 between the two support plates 12 for arranging the material strips at intervals and pulling them into the pelletizer body. In use, the material strips enter through the feed inlet 11, are arranged at intervals by the traction roller 13 between the support plates 12 and pulled into the pelletizer body 2; the drive assembly 7 drives the cutters inside the blade box 4 to cut the material strips; the large electrical box 5 and the small electrical box 6 provide power and control support; the traction roller 13 solves the problem of uneven spacing of material strips in the prior art, avoids overlapping or missed cutting during cutting, reduces particle length fluctuation and flattening phenomenon, reduces the frequency of downtime for adjustment, and improves the quality of subsequent processing.

[0031] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made 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.
