Description

Technical Field

[0001] This invention relates to the field of polymer material processing technology, specifically to a granulator that facilitates particle size adjustment. Background Technology

[0002] In the field of processing polymer materials such as plastics, granulators are key equipment for producing granular raw materials. Their function is to turn molten polymer materials into uniform granules for easy transportation or subsequent processing.

[0003] Considering the different subsequent processing techniques, granulators need to have the ability to adjust different particle sizes. Currently, traditional granulators used for polymer materials still suffer from inefficient particle size adjustment methods. Most equipment relies on changing templates or cutters with different aperture sizes to achieve particle size adjustment, which is not only cumbersome to operate but also requires stopping the machine for disassembly, seriously affecting production efficiency. At the same time, replacing the blades of granulators is cumbersome, and traditional equipment usually uses multiple bolts to fix the blades, requiring disassembly of each blade during replacement, which is time-consuming and labor-intensive.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-7 This invention provides a technical solution: a granulator for easy particle size adjustment, comprising an extruder housing 1, a motor 4, and a coupling 5, and further comprising a particle size adjustment extrusion mechanism 2 and a quick-change cutting mechanism 3. The motor 4 is connected to the left side of the quick-change cutting mechanism 3 via the coupling 5, and the output end of the motor 4 is fixedly connected to the left end of the coupling 5. The extruder housing 1 is located on the right side of the quick-change cutting mechanism 3, which is used for cutting and granulation. The particle size adjustment extrusion mechanism 2 includes a base head 21, a fixed extrusion assembly 22, and a movable extrusion assembly 23. The right end of the base head 21 is fixedly connected to the discharge end of the extruder housing 1. The right end of the fixed extrusion assembly 22 is connected to the base head 21. The movable extrusion assembly 23 is located between the fixed extrusion assembly 22 and the base head 21, and is connected to both the fixed extrusion assembly 22 and the base head 21. The fixed extrusion assembly 22 is located on the right side of the quick-change cutting mechanism 3, and the fixed extrusion assembly 22 and the movable extrusion assembly 23 cooperate to adjust the particle size.

[0026] In this invention, a polymer material is placed in the extruder housing 1. The extrusion particle size of the polymer material is adjusted by the combined action of the base head 21, the fixed extrusion assembly 22, and the movable extrusion assembly 23. The motor 4 is started, and the quick-change cutting mechanism 3 is driven by the coupling 5 to rotate and cut the extruded polymer material to form a granular product.

[0027] Please see Figures 3-4 The fixed extrusion assembly 22 includes a fixed extrusion plate 221, which is fixedly connected to the base head 21. A handle clearance hole 224 is provided in the center of the fixed extrusion plate 221. Extrusion holes 223 that cooperate with the movable extrusion assembly 23 are provided on the fixed extrusion plate 221. The extrusion holes 223 are divided into large extrusion holes and small extrusion holes according to their diameter. Large extrusion holes and small extrusion holes with the same number of groups are distributed in an equidistant circular array on the fixed extrusion plate 221. Each group of large extrusion holes and small extrusion holes are distributed at equal intervals along the radial direction. Two fixing locking holes 222 for cooperating with the movable extrusion assembly 23 are provided at the edge of the surface of the fixed extrusion plate 221. The two fixing locking holes 222 are symmetrically distributed along the same radial direction.

[0028] like Figure 3 and Figure 4As shown, the movable extrusion assembly 23 includes a movable extrusion plate 231 and a rotating handle 232. The movable extrusion plate 231 is rotatably connected to the fixed extrusion plate 221 and the base head 21 respectively. The rotating handle 232 is fixedly connected to the center of the movable extrusion plate 231. The movable extrusion plate 231 has four rectangular adjustment and clearance holes 234 that are equidistantly distributed radially. The adjustment and clearance holes 234 are aligned with different extrusion holes 223 to allow the raw material to be extruded from different extrusion holes 223, thereby achieving the effect of adjusting the particle size. Two sets of four movable locking holes 233 are provided at the edge of the surface of the movable extrusion plate 231. Each set of movable locking holes 233 is symmetrically distributed in pairs along the same radial direction. The inner walls of the movable locking holes 233 and the fixed locking holes 222 are threaded. The movable locking holes 233 and the fixed locking holes 222 are fixed by means of bolts and nuts passing through the movable locking holes 233 and the fixed locking holes 222.

[0029] The surface of the rotary handle 232 is covered with a silicone layer to increase friction and facilitate rotational adjustment.

[0030] In this invention, rotating the handle 232 rotates the movable extrusion plate 231. When the adjustment clearance hole 234 on the movable extrusion plate 231 is aligned with the small extrusion hole in the extrusion hole 223, the extruded particle size is smaller. When the adjustment clearance hole 234 on the movable extrusion plate 231 is aligned with the large extrusion hole, the extruded particle size is larger. The appropriate size is selected according to the actual production needs. After the size is selected, the movable locking hole 233 and the fixed locking hole 222 of the bolt and nut are fixed by bolts and nuts. At this time, the movable extrusion plate 231 and the fixed extrusion plate 221 are fixed, which can meet the needs of diversified processing of polymer materials. At the same time, this adjustment method is simple to operate and does not require long-term downtime for replacement, thus also taking into account the overall production efficiency.

[0031] Please see Figure 5-7 The quick-change cutting mechanism 3 includes a quick-change assembly 31, blades 32, and a rotating shaft 33. The quick-change assembly 31 and blades 32 are in multiple sets, with the same number of sets and corresponding one-to-one. Each set of blades 32 is connected to each set of quick-change assemblies 31. The blades 32 and quick-change assemblies 31 are distributed in a circumferential array with equal spacing along the outer side of the rotating shaft 33. Mounting holes are provided on the blades 32, and the cutting head of the blades 32 is in contact with the surface of the fixed extrusion plate 221. All sets of quick-change assemblies 31 are connected to the rotating shaft 33. The left end of the rotating shaft 33 is fixedly connected to the coupling 5. The quick-change assembly 31 is used to quickly and conveniently replace the blades 32.

[0032] To ensure cutting performance, the quick-change blade assembly 31 and the blade 32 have at least two sets.

[0033] like Figure 5-7As shown, the quick-change blade assembly 31 includes a blade clamping block 311, a locking component, and a fixing component. The blade clamping block 311 is fixedly connected to the rotating shaft 33. The blade clamping block 311 has fixing holes for cooperating with the fixing component and the blade 32. The blade clamping block 311 is used to place the blade 32. The locking component is connected to the fixing component. The two work together to realize the quick replacement of the blade 32.

[0034] like Figure 5-7 As shown, the locking assembly includes a push block 314 and a locking ring 315. The locking ring 315 is rotatably connected to the rotating shaft 33. The locking ring 315 has a mounting hole that matches the locking hole 316. The mounting hole has the same diameter as the mounting hole on the blade 32. The rotating shaft 33 has a locking hole 316 for fixing the locking ring 315 and the rotating shaft 33. Both the locking hole 316 and the mounting hole have threads. The locking ring 315 is fixedly connected to the rotating shaft 33 by bolts and nuts. The locking ring 315 is fixedly connected to the push block 314, which is used to push the fixing assembly.

[0035] like Figure 5-7 As shown, the fixing assembly includes a spring 312 and a locking pin 313. One end of the spring 312 is fixedly connected to the end of the cutter clamping block 311 near the fixed extrusion plate 221, and the other end of the spring 312 is fixedly connected to the upper end of the locking pin 313. The cutter clamping block 311 is inserted into the locking pin 313.

[0036] In this invention, the blade 32 is placed in the cutter clamping block 311, aligning the mounting hole on the blade 32 with the fixing hole on the cutter clamping block 311. The locking ring 315 is rotated, causing the push block 314 to push the locking pin 313, which then enters the fixing hole of the cutter clamping block 311. At this point, a bolt and nut are passed through the mounting hole and locking hole 316 on the locking ring 315. The motor 4 starts, driving the rotating shaft 33 to rotate via the coupling 5. The rotating shaft 33 drives the cutter clamping block 311 and the blade 32 to rotate, and the blade 32 cuts the product extruded from the surface of the fixed extrusion plate 221. When the blade 32 needs to be replaced, simply reset the locking ring 315, replace it with a new blade 32, and repeat the above operation. This method allows for the replacement of the blade 32 by removing only one bolt and nut from the locking ring 315 and the locking hole 316 without affecting positioning accuracy, making it convenient and quick.
