[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes an extrusion cylinder 1 and a cutting head 2; the cutting head 2 is located on the left side of the extrusion cylinder 1; It also includes: The bracket 3 is fixed on the housing of the cutting head 2. The rotating rod 4 is screwed onto the vertical rod of the bracket 3 by means of a shaft seat. The bracket 3 plays a positioning role and fixes the position of the rotating rod 4. Turntable 5 is fixedly sleeved on rotating rod 4, and turntable 5 is connected to rotating rod on cutting head 2 by belt transmission. By using the transmission between turntable 5 and belt, cutting head 2 and turntable 5 rotate synchronously, thereby driving rotating rod 4 and cutting head 2 to rotate synchronously. Limiting wheel 16 is fixedly sleeved on rotating rod in cutting head 2, and belt in turntable 5 is wound around limiting wheel 16. Limiting wheel 16 restricts the position of belt and prevents belt deviation. The top end of the connecting cylinder 6 is screwed onto the crossbar of the bracket 3 using a bearing. After the adjusting square rod 7 passes through the side wall of the bracket 3, it is set inside the connecting cylinder 6 using an adjusting component 8. The rotation of the adjusting square rod 7 is controlled by the connecting cylinder 6. The bottom end of the adjusting square rod 7 is provided with an air-guiding ring 17, and the fan blade 10 is located inside the air-guiding ring 17, which protects the fan blade 10 to a certain extent. The bevel gear set 9 is fixedly sleeved on the annular wall of the rotating rod 4 and the connecting cylinder 6. The bevel gear set 9 enables the rotating rod 4 to drive the connecting cylinder 6 to rotate synchronously. Fan blade 10, there are several fan blades 10, and they are fixed at the bottom of the adjusting square rod 7 at equal angles. The fan blades 10 are located above the cutter in the cutting head 2. By rotating the fan blades 10, the air is blown onto the cutting head 2 to cool the cutting head 2 and avoid damaging the material. Adjustment component 8 includes: Adjustment plate 11 is screwed to the top of adjustment square rod 7 by means of a rotating rod, and adjustment plate 11 is located above the crossbar of bracket 3. The position of adjustment square rod 7 is controlled by adjustment plate 11. Electric push rod 12 is fixed on the crossbar of bracket 3, and the output end of electric push rod 12 is connected to the annular wall of adjustment plate 11. Electric push rod 12 is connected to an external power supply and controls the position of adjustment plate 11. Guide rod 13 is fixed on bracket 3 and movably inserted into adjustment plate 11. Scale strip 14 is provided on the side wall of adjustment rod 7. Guide rod 13 is used to limit the movement direction of adjustment plate 11. Limiting ring 15 is fixed to the top of guide rod 13. Limiting ring 15 is set to cooperate with adjustment plate 11 to abut against it, thereby limiting the position of adjustment plate 11. A condenser tube 18 is provided on the annular wall of the extrusion cylinder 1. The condenser tube 18 is connected to an external water pump. By utilizing the dual effects of water cooling and air cooling, the cooling effect of the cutting head 2 is improved, and the material is prevented from being damaged by excessively high temperature of the cutting head 2.
[0018] When using this utility model, when the masterbatch material is extruded through the extrusion cylinder 1, the masterbatch is granulated by the rotation of the cutting head 2. When the cutting head 2 rotates, it drives the limit wheel 16 to rotate. The limit wheel 16 controls the turntable 5 to rotate synchronously through the belt. The turntable 5 drives the rotating rod 4 to rotate. The rotating rod 4 drives the connecting cylinder 6 to rotate through the bevel gear set 9. The connecting cylinder 6 drives the adjusting square rod 7 to rotate. The adjusting square rod 7 drives the fan blade 10 to rotate. The rotation of the fan blade 10 blows air onto the cutting head 2, thereby cooling the cutting head 2 and preventing the cutting head 2 from overheating and damaging the material. Simultaneously, the operator activates the electric push rod 12, which, in conjunction with the guide rod 13, controls the movement of the adjusting plate 11. The adjusting plate 11 then moves the adjusting rod 7. Based on the reading on the scale bar 14, the adjusting rod 7 is adjusted to a suitable position. By changing the distance between the fan blade 10 and the cutting head 2, the cooling effect of the fan blade 10 on the cutting head 2 is adjusted. The smaller the distance between the fan blade 10 and the cutting head 2, the better the cooling effect. In conjunction with the condenser tube 18, the temperature of the extrusion cylinder 1 is reduced, improving the cooling effect between the extrusion cylinder 1 and the cutting head 2, thus preventing high temperatures from damaging the material.
[0019] Compared with the prior art, the beneficial effects of this utility model are: The belt drives the turntable 5 and the rotating rod 4 to rotate, so that the cutting head 2 and the fan blade 10 rotate synchronously. The temperature of the cutting head 2 is reduced by air cooling to avoid the material being damaged due to excessive temperature. An adjustment component 8 is set up, and the electric push rod 12 is used in conjunction with the adjustment plate 11 to control the position of the adjustment square rod 7, thereby adjusting the distance between the fan blade 10 and the cutting head 2, and thus controlling the air cooling effect. A limit ring 15 is provided to restrict the movement of the adjusting plate 11 and prevent the adjusting plate 11 from detaching from the guide rod 13; The air intake ring 17 is set up to protect the fan blades 10 to a certain extent, while concentrating the air volume to improve the air cooling effect.
[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
