Description

PVC foaming layer extruder trades wire stitcher

Technical Field

The utility model belongs to the technical field of plastics extrusion processing, a trade net ware that is used for PVC foaming layer extruder is related to.

Background

The PVC extruder is formed by mixing PVC resin with auxiliaries such as a stabilizer, a lubricant and the like, granulating and then extruding, and can also be formed by one-step extrusion of powder. At present, the PVC foaming layer extruder conveys a foaming layer molten fluid into a PVC foaming layer die through a double-screw gun barrel for molding, the foaming layer molten fluid has impurities and is carbonized due to high temperature, the quality problems of the impurities and the carbonization exist on the surface of the molded foaming layer, the product yield is too low, the time consumption for disassembling and cleaning an inner runner is long, the production is seriously influenced, and workers complain about the serious problems.

SUMMERY OF THE UTILITY MODEL

The utility model provides a PVC foaming layer extruder trades net ware to when solving current PVC foaming layer extrusion moulding, because of there is impurity and high carbonization of temperature in the melt form fluid and cause product quality poor, the qualification rate is low, dismantles the problem that the clearance was long consuming time.

In order to solve the above problem, the utility model discloses a technical scheme is: the PVC foaming layer die comprises an extruder barrel with a muzzle and a PVC foaming layer die with a die opening, wherein the extruder barrel is connected with a connector with a feeding channel inside, the feeding channel is communicated with the muzzle, the connector is connected with a transition body with a discharging channel inside, the feeding channel is communicated with the discharging channel, a mesh plate is arranged between the connector and the transition body, the mesh plate is provided with a filter screen, the filter screen is positioned between the feeding channel and the discharging channel, the filter screen is used for blocking impurities and carbonized substances in the feeding channel, and the discharging channel is communicated with the die opening; the connector is provided with a connecting flange, the transition body is provided with a transition flange, the connecting flange and the transition flange are provided with an upper clamp body and a lower clamp body, and the upper clamp body is connected with the lower clamp body through a bolt.

In the above technical solution, a more specific technical solution may also be: the pressure sensor is connected with the alarm, and when impurities and carbide in the feeding channel are reserved to a certain amount, the pressure sensor gives an alarm due to high pressure.

Further: the extruder barrel is provided with a barrel flange, and the barrel flange is connected with the connecting body through a bolt.

Further: the mesh number of the filter screen is 200 meshes.

Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has: the mesh plate is arranged between the connecting body and the transition body, and a filter screen on the mesh plate can effectively filter fine impurities and carbonized substances and prevent the impurities from entering the die, so that the product quality is good and the qualification rate is high; the upper clamp body and the lower clamp body are connected between the connecting body and the transition body, so that the mesh plate is convenient to disassemble, replace and clean, and the problem of damaging parts by knocking does not exist.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a view from direction K of fig. 1.

In the figure: 1. an extruder barrel; 11. a blast hole; 12. a barrel flange; 2. a linker; 21. a feed channel; 22. a pressure sensor; 23. a connecting flange; 3. a transition body; 31. a discharge channel; 32. a transition flange; 4. a mesh plate; 41. a filter screen; 5. an upper clamp body; 6. a lower clamp body; 7.
