Description

Technical Field

[0001] This utility model relates to the field of twin-screw extruder technology, specifically to a twin-screw extruder with a cooling effect. Background Technology

[0002] Twin-screw extruders were developed based on single-screw extruders. Due to their excellent feeding performance, mixing and plasticizing performance, venting performance, and extrusion stability, they are now widely used in the molding and processing of extruded products.

[0003] Freshly extruded cylindrical filaments are relatively soft and hot, making them prone to deformation. Therefore, they must be cooled and hardened before pelletizing. The cooling method usually involves water cooling the filaments through a rectangular water tank. After cooling, the pellets need to be manually removed from the water tank and transported to the outside of the device, which increases the device's working time. To address this, we propose a twin-screw extruder with a cooling effect. Utility Model Content

[0004] The purpose of this invention is to provide a twin-screw extruder with a cooling effect to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A twin-screw extruder with a cooling effect, comprising a housing, a feed inlet, and a cutter. The feed inlet is located on the right side of the top of the housing, and the cutter is located above the feed inlet. The outer wall of the cutter is installed inside a support, and the lower part of the support is installed on the right side above the housing. A guide roller is located above the cutter, and the outer side of the guide roller is installed on the inner side of the support. The twin-screw extruder body is located above the guide roller. A rotating device is located on the right side inside the housing, and a storage box is located on the left side inside the housing. A conveying device is installed inside the storage box, and a baffle is installed on the right side above the storage box. Two fans are located on both sides above the conveying device, and the fans are installed inside the housing.

[0006] The rotating device includes a fixed column, a connecting column, and a first bearing. A fixed column is located on the right side of the housing. Connecting columns are installed on both sides of the fixed column. First bearings are installed at both ends of the connecting columns. The first bearing on the left side is installed inside the housing. The first bearing on the right side passes through a sealing gasket and is connected to the inner wall of the connecting box. The connecting box is installed on the right wall of the housing. A column is located above the connecting column on the right side. The left side of the column is connected to the inner wall of the connecting box via a second bearing. The right side of the column passes through the connecting box and is connected to a motor. Chain teeth are installed on the outer walls of both the column and the right connecting column. Chains are provided on the outer sides of the upper and lower chain teeth. Multiple fixing grooves are located on both sides inside the fixed column. A box is located inside the fixing groove. A connecting block is installed on the left side below the box. A water-passing groove passes through the bottom of the connecting block and connects to the outer side of a waterproof automatic slide. The waterproof automatic slide is installed on the inner wall of a storage tank. The storage tank is located inside the fixed column. Multiple water-passing grooves are located inside the fixed column.

[0007] Preferably, the housing and the feed inlet are integrated, and the housing is fixedly connected to the support and the storage box.

[0008] Preferably, the storage box and the transport device are correspondingly arranged and are fixedly connected.

[0009] Preferably, the top of the storage box is on the same horizontal line as the top of the transport device.

[0010] Preferably, the fixing columns are integrated with the fixing groove and the water passage groove, and the fixing columns are fixedly connected to the connecting columns.

[0011] Preferably, the connecting post and the first bearing are rotatably connected, and the connecting post on the right side is fixedly connected to a lower chain tooth.

[0012] Preferably, the column is fixedly connected to one of the upper chain teeth, and the column is rotatably connected to the second bearing.

[0013] Preferably, the column and the motor are connected by a drive, and the chain and the chain teeth are correspondingly arranged.

[0014] Preferably, the fixing groove is slidably connected to the box body, and the connecting blocks are fixedly connected to the bottom of the box body and the outer side of the waterproof automatic slide.

[0015] Preferably, the interior of the fixing groove is connected to the interior of the water passage groove, and the box body is provided with a mesh screen.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting up a fixed column, a connecting column, and a first bearing, the motor is started to drive the column to rotate inside the second bearing. The column drives the connecting column and the fixed column to rotate through chain teeth and a chain. At the same time, the waterproof automatic slide is started to drive the box connected to the connecting block to slide inside the fixed groove. The outer wall of the box fits against the inner wall of the container, so that granular materials with high or low density inside the container are concentrated inside the box for collection. The waterproof automatic slide resets, storing the granular materials and preventing leakage when the conveyor rotates. When the box rotates to the upper left, the waterproof automatic slide is started to pour the granular materials inside the box onto the conveyor. At the same time, the conveyor and the fan are started. The conveyor transports the granular materials while the fan dries the moisture on the outside of the granular materials, removing surface moisture, ensuring the dryness of the materials, increasing the quality of the granular materials, avoiding manual intervention, and improving efficiency.
