Description

Technical Field

[0001] This utility model relates to the field of masterbatch pelletizing technology, and more specifically, to a continuous cutting plastic masterbatch pelletizer. Background Technology

[0002] Common continuous cutting plastic masterbatch pelletizers can only cut materials continuously, but lack the function of adjusting the cutting particle size. In actual processing, the cutting blades are installed at equal intervals on the surface of the shaft in a fixed manner. The shaft rotates and works with the fixed blades to squeeze and cut the plastic strip into particles of a fixed size. However, when different particle sizes need to be cut according to production needs, shafts with different spacing cutting blades must be used. Therefore, the entire shaft needs to be replaced. The replacement of the entire shaft is a complicated operation, which ultimately leads to a reduction in processing efficiency.

[0003] In summary, to improve processing efficiency, it is necessary to solve the problem of the inability to adjust the cutting particle size, so that the cutting blades can slide on the surface of the shaft, thereby adjusting the spacing between multiple cutting blades according to actual processing requirements. Utility Model Content

[0004] The problem to be solved by the continuous cutting plastic masterbatch pelletizer provided by this utility model is that when different particle sizes need to be cut according to production needs, different spacing cutting blades must be used for the shaft body, so the entire shaft body needs to be replaced, and the replacement operation of the entire shaft body is cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous cutting plastic masterbatch pelletizer, including a pelletizer housing, an auxiliary pelletizing mechanism on the pelletizer housing, a pelletizing shaft installed inside the pelletizer housing, a sliding groove on the outer side of the pelletizing shaft, a limiting ring installed at the end of the pelletizing shaft away from the sliding groove, multiple positioning grooves inside the pelletizing shaft, multiple edge strips on the outer side of the pelletizing shaft, the end of the edge strip near the sliding groove inserted into the groove, the end of the edge strip near the limiting ring slidably connected to the limiting ring, a pelletizing blade installed on the surface of the edge strip, and a discharge mechanism on the pelletizer housing.

The positioning rod is slidably connected to the positioning groove, and the threaded head is threadedly connected to the internal screw blocks.

[0009] In a preferred embodiment, the discharge mechanism is used to discharge the material cut into granules to the outside of the pelletizer box. The discharge mechanism includes a flow guiding component and a sweeping component.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 7 A continuous cutting plastic masterbatch pelletizer includes a pelletizer housing 1, an auxiliary pelletizing mechanism on the pelletizer housing 1, a pelletizing shaft 11 installed inside the pelletizer housing 1, a sliding groove 12 on the outer side of the pelletizing shaft 11, a limiting ring 13 installed at the end of the pelletizing shaft 11 away from the sliding groove 12, multiple positioning grooves 14 inside the pelletizing shaft 11, multiple edge strips 15 on the outer side of the pelletizing shaft 11, the end of the edge strip 15 near the sliding groove 12 inserted into it, the end of the edge strip 15 near the limiting ring 13 slidably connected to it, a pelletizing blade 16 installed on the surface of the edge strip 15, and a discharge mechanism on the pelletizer housing 1.

[0025] It should be noted that the pelletizer housing 1, as the main body of the equipment, integrates all functional components and is used for continuous cutting of plastic masterbatch. The pelletizing shaft 11 is driven to rotate by the auxiliary pelletizing mechanism, and the continuous input, cutting and pellet output of plastic strips are realized in conjunction with the discharge mechanism.

[0026] It is worth noting that this design, through the structure of sliding groove 12 and positioning groove 14, allows the edge strip 15 and pelletizing blade 16 to slide and adjust their spacing along the pelletizing shaft 11 without replacing the entire shaft, thus significantly improving processing efficiency.

[0027] Refer to the instruction manual appendix Figures 3 to 5 The auxiliary pelletizing mechanism is used to control the rotational movement of the pelletizing blade 16 and to fix the position of the pelletizing blade 16. The auxiliary pelletizing mechanism includes a power component and a locking component. The output end of the power component is connected to the pelletizing shaft 11. The power component is used to control the rotational movement of the pelletizing shaft 11. The locking component is used to lock the position of the edge strip 15.

[0028] It should be noted that the mechanism includes a power unit and a locking unit. The power unit controls the rotation of the pelletizing shaft 11 to achieve cutting, while the locking unit fixes the position of the edge strip 15 to ensure that the blade does not deviate during the cutting process. The adjustable nature of the locking unit allows users to quickly adjust the spacing of the pelletizing blades 16 to change the particle size and meet different production needs.

[0029] Refer to the instruction manual appendix Figure 4 The power assembly includes a first motor 211 mounted on the surface of the pelletizer housing 1. The output end of the first motor 211 is connected to the pelletizing shaft 11. The first motor 211 is used to control the rotational movement of the pelletizing shaft 11.

[0030] It should be noted that the first motor 211 is the driving source, and its output end is directly connected to the pelletizing shaft 11. The high-speed rotation of the pelletizing shaft 11 is achieved through electrical control, which drives the pelletizing blade 16 to cooperate with the fixed blade 314 to complete the extrusion and cutting of the plastic strip.

[0031] Refer to the instruction manual appendix Figures 3 to 5 The locking assembly includes multiple internal threaded blocks 221 installed on the end of the pelletizing shaft 11 away from the limiting ring 13, a positioning rod 222 installed on the end of the edge strip 15 near the limiting ring 13, a threaded head 223 installed on the end of the positioning rod 222 near the internal threaded blocks 221, and an adjusting cover plate 224 installed on the surface of the pelletizer housing 1. The positioning rod 222 is slidably connected to the positioning groove 14, and the threaded head 223 is threadedly connected to the internal threaded blocks 221.

[0032] It should be noted that after opening the adjustment cover plate 224, the threaded head 223 is unscrewed from the inside of the inner threaded block 221 through the positioning rod 222. Then, the positioning rod 222 is pulled out from the inside of the positioning groove 14. After adjusting the position of the edge strip 15, the positioning rod 222 is inserted into the positioning groove 14 and then locked by the threaded connection between the threaded head 223 and the inner threaded block 221.

[0033] Refer to the instruction manual appendix Figures 1 to 7The discharge mechanism is used to discharge the material cut into granules to the outside of the pelletizer box 1. The discharge mechanism includes a flow guiding component and a sweeping component. The flow guiding component is used to guide the movement direction of the granules, and the sweeping component is used to remove the granules left on the flow guiding component.

[0034] It should be noted that the mechanism consists of a flow guiding component and a material sweeping component. The flow guiding component guides the cut particles to move along a preset path, and the material sweeping component removes residual particles, ensuring that the particles are smoothly discharged from the outside of the pelletizer box 1 and preventing material accumulation.

[0035] It is worth noting that by combining the guiding effect of the flow guide with the active cleaning of the material, this mechanism improves the material discharge efficiency, is suitable for high-volume scenarios, and reduces the frequency of downtime for cleaning.

[0036] Refer to the instruction manual appendix Figure 7 The flow guiding assembly includes a support plate 311 installed inside the pelletizer housing 1, two first support legs 312 installed at the lower end of the support plate 311, a mounting base 313 installed at the upper end of the support plate 311, a fixed blade 314 installed at the upper end of the mounting base 313, a guide plate 315 installed inside the pelletizer housing 1, and two second support legs 316 installed at the lower end of the guide plate 315.

[0037] It should be noted that the guide plate 315 is installed at an angle inside the pelletizer housing 1. The fixed blade 314 works with the pelletizing blade 16 to cut the plastic strip, and the guide plate 315 guides the pellets to the discharge port.

[0038] Refer to the instruction manual appendix Figure 7 The material sweeping assembly includes a second motor 321 mounted on the surface of the pelletizer housing 1, a material sweeping shaft 322 mounted on the output end of the second motor 321, and a brush 323 mounted on the outside of the material sweeping shaft 322. The second motor 321 is used to control the rotational movement of the material sweeping shaft 322.

[0039] It should be noted that the second motor 321 drives the sweeping shaft 322 to rotate, which in turn drives the brush 323 to sweep the surface of the guide plate 315, effectively removing residual particles and preventing blockage.

[0040] Refer to the instruction manual appendix Figure 6 The pelletizer housing 1 is equipped with a feeding assembly, which is used to limit the position of the material when it enters the pelletizer housing 1. The feeding assembly includes a feeding frame 411 installed on the surface of the pelletizer housing 1 and multiple partition plates 412 installed inside the feeding frame 411.

[0041] It should be noted that the feed frame 411 is installed on the surface of the pelletizer box 1, and the partition plate 412 divides the feed area into multiple channels to guide the plastic strips into the cutting area in parallel, ensuring uniform cutting.

[0042] Working principle: The plastic strip enters the pelletizer box 1 through the feed frame 411. The partition plate 412 ensures that the material is introduced into the cutting area in a parallel manner. The first motor 211 is started to drive the pelletizing shaft 11 to rotate, which drives the pelletizing blades 16 mounted on its surface to rotate synchronously. The rotating pelletizing blades 16 cooperate with the fixed blades 314 on the mounting base 313 to continuously squeeze and cut the plastic strip into granules. The cut granules fall naturally onto the surface of the inclined guide plate 315 and slide along the inclined surface of the guide plate 315 towards the discharge port. At the same time, the second motor 321 drives the sweeping shaft 322 to rotate, which drives the brush 323 on its outer side to continuously sweep the surface of the guide plate 315, forcibly cleaning the surface. To remove residual particles and ensure efficient discharge of particles from the machine, when it is necessary to change the particle size, open the adjustment cover 224, loosen the threaded head 223 to disengage it from the inner screw block 221, pull out the positioning rod 222 from the positioning groove 14, and then push the edge strip 15 to rotate along the surface of the pelletizing shaft 11 until the pelletizing knife 16 moves to the target spacing. Then insert the positioning rod 222 into the corresponding positioning groove 14, tighten the threaded head 223 and the inner screw block 221 to lock it in place, and the limit ring 13 restricts the axial displacement of the edge strip 15. This completes the shaftless adjustment of the cutting particle size. The whole process realizes continuous cutting of plastic masterbatch, on-demand adjustment of particle size and efficient discharge.

[0043] 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 noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
