Technical Field

[0001] This utility model relates to the technical field of masterbatch processing equipment, and in particular to a masterbatch cooling and cutting mechanism. Background Technology

[0002] In actual industrial production, masterbatch is a mixture composed of carrier resin, various fillers and various additives. It is a concentrated product made by uniformly loading various additives in the resin in an excessive amount. In the plastic processing process, only a small amount of masterbatch needs to be added to achieve the purpose of supplementation, reinforcement and modification, and then to produce plastic products with specific functions. Masterbatch refers to the raw material that needs to be processed into granules of specific specifications by a cooling and cutting mechanism after processing.

[0003] Existing masterbatch cooling and cutting mechanisms have many problems. On the one hand, the cooling effect is poor, and the masterbatch is directly cut at high temperature, which easily leads to severe wear of the cutter and low dimensional accuracy and irregular shape of the cut masterbatch. On the other hand, the cooling and cutting processes are independent of each other, the equipment structure is complex, the area occupied is large, the production efficiency is low, and the production cost is high. Therefore, a masterbatch cooling and cutting mechanism is proposed to address the above problems. Utility Model Content

[0024] Please see Figure 1-6This utility model provides an embodiment of a masterbatch cooling and cutting mechanism, comprising a cooling box 1, a transfer mechanism disposed at the right end of the cooling box 1, a cutting device and a cooling circulation assembly installed in the middle of the cooling box 1. The cooling box 1 is a hollow cuboid structure. The left end of the cooling box 1 is provided with a feed pipe 11 connected to an external discharge pipe. The cooling box 1 is provided with a conveyor belt 12 inside. The conveyor belt 12 is prior art and will not be described in detail here. The top right end of the conveyor belt 12 is provided with a baffle 13, which can prevent the masterbatch material from falling from the side of the conveyor belt 12 during cutting. The cooling circulation assembly includes a refrigeration unit disposed at the front of the cooling box 1. 21. The air outlet of the refrigeration unit 21 is connected to the air exchange box 23 through the pipe 22. The air exchange box 23 is equipped with an exhaust fan 24. The air outlet of the air exchange box 23 is connected to the vent 26 on the cooling plate 25 through the air outlet pipe. One end of the exhaust pipe 27 is connected to the cooling box 1, and the other end is connected to the refrigeration unit 21, forming a closed cooling loop. The bottom of the cooling plate 25 is provided with cooling grooves from front to back. The vent 26 is set on the inner side wall of the cooling groove. The cooling plate 25 is located on the top side of the conveyor belt 12. The feed pipe 11 is provided with multiple limit channels of the same size. External materials enter the corresponding cooling groove inside the cooling plate 25 through the limit channels.

[0025] The cutting device includes a slitting blade holder 32 located on the right side of the cooling plate 25. The front and rear ends of the slitting blade holder 32 are fixedly connected to the telescopic ends of the hydraulic rod 31. The hydraulic rod 31 is installed inside the front and rear side walls of the cooling box 1. The slitting blade holder 32 is equipped with multiple blades 33. The spacing between the blades 33 is the same as the width of the cooling groove inside the cooling plate 25.

[0026] The bottom right end of the cooling box 1 is provided with a locking groove, and a limiting frame 41 is installed inside the locking groove. A spring 42 is installed inside the limiting frame 41. The top of the spring 42 is fixedly connected to the bottom of the lifting block 43, and the top of the lifting block 43 is welded to the bottom of the arc-shaped protrusion 44.

[0027] The transfer mechanism includes a transfer box 51 located at the right end of the cooling box 1. The right end of the transfer box 51 is fixedly connected to the left end of the hand-held frame 52. The bottom of the transfer box 51 is equipped with a moving wheel 53. The left end of the transfer box 51 is provided with a connecting plate 54. The bottom of the connecting plate 54 is welded to the top of the extrusion arc block 55. The connecting plate 54 is inserted into the locking groove at the bottom right end of the cooling box 1. The bottom side of the extrusion arc block 55 is attached to the top side of the arc protrusion 44. When the transfer box 51 is in use, the connecting plate 54 and the extrusion arc block 55 are pressed into the locking groove at the bottom right end of the cooling box 1. The arc protrusion 44 is subjected to external pressure, which will compress the spring 42, thereby locking the connecting plate 54 and the extrusion arc block 55 to prevent the position of the transfer box 51 from moving during use.

[0028] The refrigeration unit 21 generates cold air, which is transported to the air exchange box 23 through the pipe 22. The exhaust fan 24 forces the cold air through the outlet pipe into the vent hole 26 of the cooling plate 25 to cool the material inside the cooling tank of the cooling plate 25 on the conveyor belt. After completing the heat exchange, the cold air returns to the refrigeration unit 21 through the exhaust pipe 27, forming a closed cooling cycle.

[0029] During use, external materials enter the corresponding cooling tank inside the cooling plate 25 through the limiting channel. The exhaust fan 24 pressurizes the cold air into the ventilation hole 26 of the cooling plate 25 through the exhaust pipe to cool the material inside the cooling tank of the cooling plate 25 on the conveyor belt. When the cooled material is conveyed to the position where the cooling plate 25 and the cutting device meet, the extension end of the hydraulic rod 31 drives the slitting blade holder 32 to move back and forth a unit distance. During the movement, the blade 33 can cut the masterbatch material. The cut material will fall into the transfer box 51. The staff can transfer the cut material to the designated position through the transfer box 51.
