Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, specifically a slicing machine for color masterbatch processing. Background Technology

[0002] During the production of color masterbatch, long-term cutting of high-hardness color masterbatch (such as formulations containing glass fiber and calcium carbonate) will gradually wear down the blades, leading to an increase in the gap. Regularly adjusting the blade gap is a key operation to ensure granulation quality, equipment stability, and production efficiency.

[0003] For example, the utility model patent with patent number CN202221332202.2 discloses a high-speed pelletizing device for producing plastic pellets. The pelletizing blade is adjustable and can be adapted to the position and outer edge structure by connecting the blade and the pelletizing blade. The adjustment is convenient.

[0004] However, in the above technical solution, there are multiple pelletizing blades that are evenly distributed in a ring around the pelletizing blade holder. When adjustment is required, it is necessary to adjust each blade individually by turning the screw on each blade and visually observing the gap between the pelletizing blade and the die head. Furthermore, it is very troublesome to readjust the position of each blade every time there is a periodic adjustment, which may cause positional errors of each blade and thus affect the consistency of masterbatch production.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] This utility model embodiment provides a slicing machine for color masterbatch processing, such as Figure 1-4As shown, the device includes a frame, on which an extruder head is mounted. A masterbatch extrusion disc 1 is mounted on the front side of the extruder head. The masterbatch extrusion disc 1 has several extrusion holes. A pelletizing mechanism is mounted on the front side of the masterbatch extrusion disc 1. The pelletizing mechanism includes a drive motor, a pelletizing shaft 2, a pelletizing blade holder 3, and several blades 4. The drive motor is fixed to the frame. The pelletizing shaft 2 is connected to the output end of the drive motor and extends from the drive motor toward the masterbatch extrusion disc 1. The pelletizing blade holder 3 is fixed to the end of the pelletizing shaft 2 facing the masterbatch extrusion disc 1. The outer edge of the base 3 is integrally formed with several mounting beams 5. The mounting beams 5 are inclined and the blade holders 6 are slidably mounted on the mounting beams 5. The blades 4 are provided with positioning slots and positioning bolts are inserted into the positioning slots. The blade holders 6 are provided with positioning screw holes and the positioning bolts are threaded into the positioning screw holes. Tightening the positioning bolts can cause the positioning bolts to press against the outside of the blades 4, thereby locking and unlocking the blades 4. During the initial adjustment, the distance between each blade 4 and the masterbatch extrusion disc 1 can be adjusted to achieve the optimal position for color masterbatch granulation and slicing.

[0028] Two parallel sliding blocks are provided on the rear side of the blade holder 6. Two translation slide rods 7 are provided on the sliding blocks at intervals. An adjustment groove is provided on the mounting beam 5. The adjustment groove connects the front and rear sides of the mounting beam 5. The length of the adjustment groove is greater than the length of the sliding block. The sliding block is slidably installed in the adjustment groove. The translation slide rods 7 extend rearward from the rear side of the sliding block.

[0029] The rear side of the mounting beam 5 is provided with a translational slide groove. The upper and lower side walls of the translational slide groove are provided with guide protrusions. A translational piece 8 is slidably installed inside the translational slide groove. The translational piece 8 is provided with a guide groove that is slidably connected to the sliding block. The translational piece 8 is provided with four mutually slidable inclined slot holes 9. The translational slide rod 7 is slidably inserted into the translational inclined slot holes 9. The translational piece 8 slides left and right in the translational slide groove. By changing the position of the translational inclined slot holes 9, the translational slide rod 7 is pressed to make the blade holder 6 slide up and down in the adjustment groove to adjust the position of the blade 4, so that the blade 4 is closer to or farther away from the masterbatch extrusion disc 1.

[0030] A synchronous adjustment mechanism is connected between several translation plates 8. The synchronous adjustment mechanism includes several connecting shafts 12 disposed on the rear side of the pelletizer holder 3, a transmission gear set 10 rotatably connected to the connecting shafts 12, and an adjustment knob 11 slidably mounted on the pelletizer holder 3. The transmission gear set 10 includes a transmission bevel gear 101 and a transmission spur gear 102 fixed to each other. Several connecting shafts 12 are respectively disposed on the side close to the translation plates 8. The translation plates 8 have an integrally formed translation rack 13 that meshes with the transmission bevel gear 101 on the side facing the transmission bevel gear 101. The adjustment knob 11 is slidably sleeved on the outside of the pelletizer shaft 2. An adjustment gear 14 is disposed in the middle of the adjustment knob 11. The adjustment gear 14 meshes with several transmission spur gears 102. The connecting shafts 12 are connected to the rear side of the pelletizer holder 3. A support beam plate 15 is fixed to the top of the 12. The support beam plate 15 slides against the rear side of the transmission gear set 10. A knob 11 block is fixed to the outside of the adjustment knob 11. Corresponding locking tooth rings 16 are provided on the support plate and the knob 11 block. The locking tooth rings 16 are provided with mutually cooperating locking teeth and locking grooves at intervals. A connecting groove is provided on the side of the adjustment gear 14 facing the support beam plate 15. A locking tension spring 17 is connected between the connecting groove and the support beam plate 15. The locking tension spring 17 can lock the locking tooth rings 16 of the adjustment knob 11 against the locking tooth rings 16 on the support beam plate 15 to prevent the adjustment knob 11 from rotating synchronously with the pelletizer 3 during normal operation and prevent displacement during rotation, thus ensuring the stability of the blade 4 position.

[0031] Working principle:

[0032] In this invention, during the initial adjustment, the blade 4 is initially installed by inserting a positioning bolt into its positioning slot. The position of the blade 4 on the blade holder 6 is then adjusted by moving the bolt, thus adjusting the distance between the blade 4 and the masterbatch extrusion disc 1. The positioning bolt is then tightened, pressing the blade 4 firmly against the blade holder 6 to form a fixed position. Each blade 4 is positioned and installed in this way, allowing for the granulation and slicing of the masterbatch. When the blade 4 gradually wears down and requires positioning adjustment, the adjustment knob 11 is manually pulled back to lock the locking ring 16 tightly against the support beam plate 15. The toothed rings 16 disengage to unlock. By rotating the adjustment knob 11, the adjustment gear 14, the transmission gear set 10, and the translation rack 13 on the translation plate 8 mesh with each other, so that multiple translation plates 8 can slide synchronously in the translation groove. They change position sequentially through the translation inclined slot hole 9, press the translation slide rod 7 to make the blade holder 6 slide up and down in the adjustment groove, so that the blades 4 fixed on the blade holder 6 slide synchronously closer to or away from the masterbatch extrusion disk 1, thereby realizing the position of multiple blades 4. The operation is simple and the synchronization of the blades 4 is high, which improves the uniformity of color masterbatch granulation.
