[0002] Plastic is a high molecular compound polymerized from monomers through addition polymerization or condensation polymerization. Commonly known as plastic or resin, it can freely change its composition and form. Plastic is formed by pouring synthetic plastic materials into a mold to form the final product. One of the plastic materials is plastic masterbatch. Plastic masterbatch is a special concentrated material. With it, there is no need to add plastic additives, saving a lot of materials. During the production of plastic masterbatch, it needs to be cooled and formed.

[0004] The following problems exist in this technical solution: Although the plastic masterbatch can be cooled and formed, when it is necessary to cut the plastic masterbatch extruded by the screw extruder, additional cutting equipment is required for cutting, which is rather inconvenient. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages in the prior art that although the plastic masterbatch can be cooled and formed, when it is necessary to cut the plastic masterbatch extruded by the screw extruder, additional cutting equipment is required for cutting, which is rather inconvenient, and to propose a plastic masterbatch cooling and forming device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A plastic masterbatch cooling and forming device, comprising a frame body and an extrusion box for extruding plastic masterbatch. A cooling block is fixedly arranged at the top of the frame body. Support plates for supporting the extrusion box are welded to both bottom sides of the extrusion box. The bottom of the support plate is fixedly connected to the top of the cooling block. A motor is fixedly arranged at the top of the extrusion box. A rotating rod is rotatably connected to the inner wall of the top of the extrusion box, and the bottom end of the rotating rod is rotatably connected to the inner wall of the bottom of the extrusion box. A spiral conveying blade is welded on the rotating rod. The output end of the motor penetrates through the top of the extrusion box and is fixedly connected to the top end of the rotating rod. A feeding hopper is fixedly arranged at the top of the extrusion box and is communicated therewith. An extrusion hole is opened at the bottom of the extrusion box. A cooling channel is opened in the cooling block. A containing cavity for containing ice cubes and ice water is opened in the cooling block. A net plate for blocking ice cubes is fixedly arranged on the inner wall of the bottom of the cooling block. A drain pipe is fixedly arranged on one side of the cooling block and is communicated therewith. A valve is arranged on the drain pipe. A collecting box for collecting sprayed water is fixedly arranged on the inner wall of the bottom of the frame body. The collecting box is located directly below the cooling channel;

[0008] A cutting mechanism, which is arranged on the frame body and is used for cutting the cooled plastic masterbatch;

[0009] A conveying mechanism, which is arranged on the frame body and is used for spraying water to cool the extruded plastic masterbatch.

[0010] In a possible design, the cutting mechanism includes a fixing plate, an electric push rod, a mounting seat, a blade, a reinforcing plate and a baffle plate. The two sides of the fixing plate are respectively fixedly connected to the inner walls of the two sides of the frame body. The fixed part of the electric push rod is fixedly connected to one side of the fixing plate. The mounting seat is fixedly connected to the telescopic part of the electric push rod. The blade is located on one side of the mounting seat. The top of the reinforcing plate is fixedly connected to the bottom of the cooling block. One side of the baffle plate is fixedly connected to one side of the reinforcing plate.

[0011] In a possible design, the conveying mechanism includes a first water pump, a second water pump and an annular box. The bottom of the first water pump is fixedly connected to the inner wall of the bottom of the frame. A first pipe is fixedly arranged at the input port of the first water pump. One end of the first pipe is fixedly connected and communicated with one side of the collection box. A second pipe is fixedly arranged at the output port of the first water pump. One end of the second pipe is fixedly connected and communicated with one side of the cooling block. The bottom of the second water pump is fixedly connected to one side of the top of the cooling block. A third pipe is fixedly arranged at the input port of the second water pump. One end of the third pipe is fixedly connected and communicated with one side of the cooling block. The outer side of the annular box is fixedly connected to the inner wall of the cooling channel. The annular box is of a hollow structure. A plurality of nozzles are fixedly arranged and communicated with the inner wall of the annular box. A fourth pipe is fixedly arranged at the output port of the second water pump. One end of the fourth pipe is fixedly connected and communicated with the top of the annular box.

[0012] In a possible design, a collection basket for collecting the cut plastic masterbatch is arranged on the collection box. Drainage holes are formed in the collection basket.

[0013] In a possible design, an adding hole for conveniently adding ice cubes and ice water is formed in the top of the cooling block. An opening and closing cover is hinged to the top of the cooling block through a hinge. A handle is fixedly arranged on one side of the top of the opening and closing cover.

[0014] In a possible design, a slot is formed in one side of the mounting seat. One end of the blade is inserted into the slot. Two bolts for fixing the blade are threadedly connected to the mounting seat. Two jacks are formed in the blade. The bottom ends of the bolts are inserted into the jacks of the blade.

[0015] In this application, during use, the raw materials after kneading are added into the extrusion box through the feeding hopper. Driven by the motor, the rotating rod starts to rotate, driving the spiral conveyor blade to rotate, thereby pushing the plastic masterbatch towards the bottom of the extrusion box. When the plastic masterbatch is pushed to the bottom of the extrusion box, it is extruded through the extrusion holes to form the initial form of the plastic masterbatch. Then, the extruded plastic masterbatch enters the cooling channel of the cooling block. Since there is a receiving cavity in the cooling block, ice cubes or ice water can be placed in the receiving cavity. Through the low-temperature effect of the ice cubes or ice water, the plastic masterbatch passing through the cooling channel is cooled, causing it to rapidly cool down and solidify into a shape (where the material of the cooling block is a heat-conducting metal material, such as iron, steel, copper, etc.). At the same time, the start of the second water pump generates suction, and the cold water in the cooling block is transported to the annular box through the fourth pipeline, and then sprayed onto the plastic masterbatch in the cooling channel through multiple nozzles on the annular box to achieve secondary cooling and enhance the cooling effect. The sprayed water will drip into the collection basket on the collection box and then drip into the collection box through the water drainage holes of the collection basket. The first water pump extracts water from the collection box and transports it to the cooling block through the second pipeline to provide a cooling water source for the cooling block, realizing the recycling of water through the first water pump and the second water pump;

[0016] Then the plastic masterbatch comes out from the bottom end of the cooling channel. When the plastic masterbatch reaches the position of the blade and the blocking block, the electric push rod is started. The telescopic part of the electric push rod pushes the mounting seat forward, and the movement of the mounting seat drives the movement of the blade. Then, the blade pushes the plastic masterbatch to the position of the blocking block, and the plastic masterbatch is cut by the thrust of the electric push rod and the blade to form plastic masterbatch of a certain length, so that the plastic masterbatch can be cut. The cut plastic masterbatch falls into the collection basket directly below the cooling channel for collection. When it is necessary to add ice cubes or ice water, the opening and closing cover can be opened, and the ice cubes or ice water are added into the receiving cavity through the adding hole. Among them, the electric push rod is a waterproof electric push rod.

[0017] The beneficial effects of the present utility model are as follows:

[0018] In the present utility model, for the plastic masterbatch cooling and forming device, through the cutting mechanism, the telescopic part of the electric push rod pushes the mounting seat forward, and the movement of the mounting seat drives the movement of the blade. Then, the blade pushes the plastic masterbatch to the position of the blocking block, and the plastic masterbatch is cut by the thrust of the electric push rod and the blade to form plastic masterbatch of a certain length, so that the plastic masterbatch can be cut;

[0019] In this utility model, for the plastic masterbatch cooling and forming device, through the conveying mechanism, the start of the second water pump generates suction. The cold water in the cooling block is transported to the annular box through the fourth pipeline, and then sprayed onto the plastic masterbatch in the cooling channel through multiple nozzles on the annular box to achieve secondary cooling and enhance the cooling effect. The sprayed water will drip into the collection basket on the collection box and then drop into the collection box through the water drainage holes of the collection basket. The first water pump extracts water from the collection box and transports it to the cooling block through the second pipeline to provide water source for the cooling block. The recycling of water is realized through the first water pump and the second water pump;

[0020] In this utility model, the plastic masterbatch can be cut off through the cutting mechanism, and the plastic masterbatch can be sprayed with water for water cooling through the conveying mechanism, and at the same time, the cold water can be recycled. Brief Description of the Drawings
