Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of granulators, in particular to a self-cleaning die head of an extrusion granulator. Background Art
[0002] Extrusion granulator is a kind of equipment used to extrude, crush and granulate raw materials. It is usually used in pharmaceutical, chemical, food, agriculture and other related industries. The extrusion granulator extrude the raw materials through the extrusion mechanism to make the raw materials dense, and crush them through rotating blades or grinders to finally form granular particles. The extrusion granulator needs to clean the die head regularly after use, because there will be raw materials left on the surface of the die head during the operation of the extrusion granulator. If it is not cleaned, it will cause blockage, affect production efficiency and even damage the equipment.
[0003] Currently, commonly used cleaning methods include wiping the die surface with a cleaning cloth, cleaning the die with a cleaning agent, etc. However, the above cleaning operations all require the outer shell to be removed in order to manually clean the extrusion holes opened on the die surface, which is cumbersome and inconvenient for the staff to operate. Utility Model Content
[0004] The utility model aims to provide a self-cleaning die head of an extrusion granulator to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning extrusion granulator die head, comprising a die head and a shell, a shaft rod is rotatably installed at one end of the interior of the shell, a shaft sleeve is sleeved on the surface of the shaft rod, a tool holder is connected to the outer surface of the shaft sleeve, a fastening bolt is rotatably installed at the top end of the interior of the tool holder, a scraper is pressed against the bottom end of the fastening bolt, and the scraper is arranged in the middle of the interior of the tool holder.
[0006] When using a self-cleaning extrusion granulator die head in the technical solution, the staff needs to first connect the extrusion granulator to an external power supply and control the operation of the utility model through a controller. The staff pours the raw materials into the interior of the extrusion granulator, and the spiral rod in the extrusion granulator will squeeze the raw materials into the interior of the die head and extrude them through the extrusion holes opened in the die head. When the raw materials are extruded, the staff starts the first motor, and the first motor rotates the cutter connected to the output end. The rotating cutter cuts and granulates the raw materials extruded from the extrusion holes. The granulated raw materials will fall into the interior of the discharge hopper and be discharged from the interior of the shell through the discharge hopper. After the utility model has been used for a certain period of time, the staff needs to clean the raw material residues adhering to the surface of the extrusion holes. Specifically, The operation is that the staff starts the second motor, and the second motor rotates the shaft connected to the output end. After the shaft rotates, the thread on its surface will engage with the thread on the inner surface of the sleeve. The engagement of the thread will cause the sleeve to move on the surface of the shaft, and the sleeve will move with the tool holder connected to the outer surface. After the tool holder moves, the scraper fixed inside it will move with it and scrape off the raw material residues adhered to the surface of the extrusion hole. Some raw material residues will directly fall into the discharge hopper and be discharged through the discharge hopper, while some raw material residues will adhere to the surface of the scraper. After the scraper has been used for a certain period of time, the staff needs to disassemble the outer shell, tighten the fastening bolts to take the scraper out of the tool holder and clean or replace it for subsequent use.
[0007] Preferably, a first motor is fixed to the outer front surface of the housing, and a cutter is connected to the output end of the first motor. Through the cooperation of the first motor and the cutter, the raw material extruded through the extrusion hole can be cut, achieving the effect of cutting and granulation.
[0008] Preferably, the outer rear surface of the shell is connected with a die head, and an extrusion hole is formed inside the die head. Through the cooperation between the die head and the extrusion hole, the raw materials transmitted by the extruder can be extruded through the inside, thereby achieving the effect of extrusion granulation.
[0009] Preferably, a slide rod is provided at the other end of the inner part of the housing, a slide sleeve is provided on the surface of the slide rod, and a tool holder is connected to the outer surface of the slide sleeve. Through the cooperation between the slide sleeve and the slide rod, the screw rod with threads on the surface can stabilize one end of the tool holder in meshing when the screw sleeve with threads on the inner surface rotates, thereby achieving the effect of stabilizing the lifting and lowering movement of the tool holder.
[0010] Preferably, a second motor is fixed to the outer top surface of the housing, and an output end of the second motor is connected to a shaft rod. By providing the second motor, the shaft rod can be rotated, thereby achieving a power output effect.
[0011] Preferably, the outer bottom surface of the housing is provided with a discharge hopper. By providing the discharge hopper, the raw material particles extruded through the extrusion hole and the raw material residues scraped off by the scraper can be discharged through this hopper, thereby achieving the effect of providing a unified discharge position.
[0012] Preferably, the inner surface of the sleeve and the surface of the shaft rod are both provided with threads and mesh with each other. Through the cooperation between the sleeve and the shaft rod, since both the inner surface and the surface are provided with threads, when the shaft rod rotates, the threads on its surface will mesh with the threads on the inner surface of the sleeve, and the engagement of the threads will cause the sleeve to move on the surface of the shaft rod, thereby achieving the effect of indirectly controlling the lifting and lowering movement of the tool holder by the engagement of the threads.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model installs a shell on the outer surface of the die head, and a scraper that can move up and down is installed inside the shell. The scraper that moves up and down can scrape the raw material residues adhering to the surface of the extrusion holes opened on the surface of the die head. The cleaning operation can be carried out in the shell without dismantling, which is convenient for the staff to carry out cleaning operations. BRIEF DESCRIPTION OF THE DRAWINGS
