Description

Technical Field

[0001] The invention relates to the field of masterbatch production, in particular to a masterbatch water-cooling granulation device. Background Art

[0002] At present, masterbatch is a material widely used in the fields of pharmaceuticals, food, chemicals, etc. The cooling link is crucial in its production process, and the production of masterbatch requires a granulator, of which the water-cooled strand granulator is one of the commonly used granulators. The material is extruded in strips through an extruder, then enters a cooling pool for water cooling, and finally cut into masterbatch particles by a pelletizer.

[0003] The existing masterbatch water-cooling granulation device includes an extruder, a water-cooling pool and a cutting machine. After the material enters the extruder, it is extruded into strips and enters the water-cooling pool for cooling and shaping, and then transported to the cutting machine for cutting to form masterbatch.

[0004] Regarding the above-mentioned related technologies, since the belt may break during the strip transportation process, especially during the transportation in the water cooling pool, when the belt breaks, the operator needs to find the position of the broken belt underwater, and then connect it and transport it again; however, in actual use, the water in the water cooling pool is not clear and transparent, and the strip product itself is white, so it takes a lot of time to find the position of the broken belt, affecting the overall processing efficiency. Summary of the invention

[0005] In order to quickly find the location of the broken belt and improve processing efficiency, the present application provides a masterbatch water-cooling granulation device.

[0006] The present application provides a masterbatch water-cooling granulation device, which adopts the following technical solution:

[0007] A masterbatch water-cooling granulation device comprises an extruder, a water-cooling pool and a cutting machine which are arranged in sequence horizontally, the two ends of the water-cooling pool are respectively located at the discharge port of the extruder and the discharge port of the cutting machine, and also comprises a pair of splicing tables, the two splicing tables are respectively installed at the two end positions in the water-cooling pool, the splicing tables are arranged near the pool mouth of the water-cooling pool, and the splicing tables are provided with guide grooves for strip products to be inserted at intervals in a direction perpendicular to the water-cooling pool; the two splicing tables are slidably installed on the splicing tables in a direction close to or away from each other, and the water-cooling pool is installed with driving components respectively used to drive the two splicing tables to slide.

[0008] By adopting the above technical solution, after the extruder extrude several strips of products, they will first pass through one end of the guide groove on the splicing table close to one end of the extruder, then enter the water cooling pool for cooling, and then be transported out from one end of the guide groove on the splicing table at the other end, and enter the cutting machine for cutting; when the strip product breaks in the water cooling pool, the extruder and the cutting machine are stopped first, and then the driving assembly is started to drive the two splicing tables to slide towards each other; since the splicing table is installed at the pool mouth of the water cooling pool, the strip products located underwater will pass through the guide groove on the splicing table; when one of the splicing tables moves to the position of the broken belt, one end of the broken belt will be lifted out of the water, and the operator can pull up this end ; The other splicing table can speed up its movement and get closer. Since the length of the strip product in the water-cooling pool is greater than the length of the water-cooling pool, the operator only needs to wait until the splicing table moves to a certain distance before the operator can find the corresponding broken belt through the strip product in the corresponding guide groove, and the operator can complete the splicing operation; the above structure does not require the operator to find the position of the broken belt in the opaque water-cooling pool. It only needs to wait for one of the splicing tables to move to the point where one end of the broken belt is lifted up and stand at that position until the other splicing table moves close to that position, and then find the other end of the broken belt through the guide groove position corresponding to the broken belt, and the splicing work can be completed, and then the extruder and cutting machine can be restarted for processing, which greatly improves the processing efficiency.

[0014] By adopting the above technical solution, the end of the driving rod that is inserted out of the supporting plate is pressed so that the hole wall of the through hole leaves the limiting groove, thereby releasing the restraint on the plug-in rod; and when the plug-in rod is inserted into the plug-in hole and the plug-in rod passes through the through hole, the driving rod is released, and the driving rod can be reset by the elastic member, and the hole wall of the through hole is reinserted into the limiting groove, thereby completing the connection between the splicing platform and the supporting plate; the operation is convenient and the disassembly and assembly efficiency is high.
