Technical Field
[0001] The utility model relates to the technical field of masterbatch processing, in particular to a pelletizing device for processing plastic masterbatch. Background Art
[0002] Plastic masterbatch is a polymer obtained by uniformly encapsulating an unusually large amount of pigment or dye within a resin. Masterbatch plays a crucial role in the production of plastic products, enabling them to achieve specific colors, properties, and characteristics. As the plastics industry continues to grow, demand for masterbatch continues to grow.
[0003] During the masterbatch processing process, the masterbatch is extruded by an extruder and pelletized by a pelletizing device. In the existing technology, the traditional pelletizing device has major defects. For example, the traditional masterbatch pelletizing device cannot adjust the masterbatch cutting length. When the length needs to be changed, the pelletizing device can only be replaced, which is very cumbersome and has high economic consumption. Therefore, a masterbatch pelletizing device is urgently needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a pelletizing device for processing plastic masterbatch.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A pelletizing device for processing plastic masterbatch comprises a body, an extruder is mounted on the upper end of the body, an extrusion head is provided at the end of the extruder, a rotating rod is rotatably connected to the body, a cutting knife that matches the extrusion head is fixedly sleeved on the end of the rotating rod, a driving mechanism for driving the cutting knife is provided on the side wall of the body, the driving mechanism comprises a transmission rod rotatably connected to the side wall of the body, a first gear and a second gear are fixedly sleeved on the transmission rod, a sleeve is sleeved on the rotating rod, a third gear and a fourth gear are fixedly sleeved on the sleeve, and a moving mechanism for moving the sleeve is provided on the side wall of the body.
[0007] Preferably, the moving mechanism includes a moving plate rotatably sleeved on a sleeve, an electric push rod is fixedly connected to the side wall of the body, and a telescopic end of the electric push rod is fixedly connected to the side wall of the moving plate.
[0008] Preferably, four limiting strips distributed at equal intervals in the circumferential direction are fixedly connected to the side wall of the rotating rod, and four limiting grooves matching with the limiting strips are formed on the inner wall of the sleeve.
[0009] Preferably, the first gear cooperates with the third gear, and the second gear cooperates with the fourth gear.
[0010] Preferably, a transmission wheel is fixedly sleeved on the transmission rod and the output shaft of the extruder, and the two transmission wheels are connected by a belt transmission.
[0011] Preferably, a collecting tank is fixedly connected to the side wall of one end of the machine body close to the extrusion head, a circulating pump and a cooler are provided on the front side wall of the machine body, the collecting tank is connected to the cooler and the circulating pump, and the circulating pump is connected to the cooler.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. By setting a driving mechanism and a moving mechanism, in the initial state, the second gear is engaged with the fourth gear, and the extruder works. Under the action of the transmission wheel and the belt, the transmission rod rotates. At this time, the second gear rotates, driving the fourth gear engaged with it to rotate, thereby driving the sleeve to rotate. Under the action of the limit bar and the limit groove, the sleeve drives the rotating rod to rotate, drives the cutting knife to rotate, completes the pelletizing, drives the telescopic end of the electric push rod to retract, drives the sleeve to move, drives the third gear to engage with the first gear, and changes in the transmission ratio change the rotation speed of the rotating rod, thereby achieving the effect of adjusting the pelletizing size.
[0014] 2. By setting up a collection tank and a circulation pump, cold water is poured into the collection tank. Under the action of the circulation pump, the cold water circulates in the collection tank, the circulation pump and the cooler. The cut masterbatch falls into the collection tank to achieve rapid cooling, avoiding the masterbatch from sticking due to failure to cool in time, which affects product quality.
