Abstract
The utility model discloses a cooling device used for a feeding drum, which comprises a rotary connector installed on the feeding drum, a cooling liquid input pipe connected with the rotary connector, a cooling liquid output pipe and a control valve, wherein the rotary connector is coaxial with the feeding drum; the rotary connector extends to an inner cavity of the feeding drum and synchronously runs with the feeding drum; the temperature of the feeding drum is kept at the normal temperature or below the normal temperature through the cooling function of the cooling device, the phenomenon that the rubber material is burnt due to long-term heating, and the quality of the produced electric wire and cable is ensured; and the since the temperature of the feeding drum is kept at the normal temperature or below the normal temperature, the operator is prevented from being scalded, and the use safety of the extruding machine is greatly enhanced.
Description
Technical field
The utility model relates to extruder drawing-in device field, especially a kind of cooling device of feeding cylinder.
Background technology
Being used for plastic granulating, rubber at present, to make the extrusion equipment of line, various PLASTIC LAMINATED moulding a lot, and extrusion equipment all needs to use feeding cylinder (feeding roller) with materials such as rubber input extruder spiral shell cylinder mostly.After extruder was connected power supply, the feeding cylinder promptly was in the state of running up, owing to lack effective cooling system, make the temperature of whole feeding cylinder more and more higher, make rubber be transfused to the heat that has absorbed the feeding cylinder before the spiral shell cylinder, cause rubber to burn easily, influence the quality of electric wire.The feeding cylinder be unitary fixed on extrusion equipment, in default of the cause of cooling system, the temperature of feeding cylinder is delivered to the extruder fuselage, causes the extruder body temperature to raise, operating personnel are scalded easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple and reasonable, effectively reduce the cooling device of feeding bowl temperature and feeding cylinder safe in utilization.
Goal of the invention of the present utility model is achieved in that a kind of cooling device of feeding cylinder, it is characterized in that: comprise the swivel joint that is installed on the feeding cylinder, the coolant inlet pipe that is connected with swivel joint, cooling fluid efferent duct and control valve, described swivel joint is coaxial with the feeding cylinder.
Described swivel joint extends to the feeding drum cavity, swivel joint and the run-in synchronism of feeding cylinder.
Described swivel joint is the rotary swivel joint in double loop.
Described control valve is a tap.
The utility model improves the feeding cylinder of prior art, on the feeding cylinder, set up cooling device, this cooling device mainly comprises swivel joint, coolant inlet pipe, cooling fluid efferent duct and control valve, and swivel joint extends to the feeding drum cavity, and with the run-in synchronism of feeding cylinder.By the refrigerating function of cooling device, the feeding bowl temperature remains on normal temperature or is lower than normal temperature, avoids occurring rubber mass and is heated for a long time and burns, and has guaranteed to produce the quality of electric wire.Because the feeding bowl temperature remains on normal temperature or is lower than normal temperature, effectively avoids the operator to be scalded, and improves the safety in utilization of extruder equipment greatly.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in 1, the cooling device of feeding cylinder of the present utility model comprises swivel joint 1, coolant inlet pipe 2, cooling fluid efferent duct 3 and control valve 4 with reference to the accompanying drawings.Swivel joint 1 is installed on feeding cylinder 10 1 sides and extends to feeding cylinder 10 inner chambers (having the inner chamber with swivel joint 1 adaptive installation in the feeding cylinder 10), and swivel joint 1 is coaxial with feeding cylinder 10, so swivel joint 1 and 10 run-in synchronisms of feeding cylinder.Swivel joint 1 adopts the rotary swivel joint in double loop, and the good airproof performance of swivel joint 1 resistance to wears, the life-span is long, corrosion-resistant, do not leak, and the situation of its inner seal wearing and tearing can be learnt by the outward appearance range estimation, can prevent machinery shutdown or mechanical failure.Owing in the rotary swivel joint 1 in double loop independent pipeline is arranged, can select for different working condition demands, the cooling fluid in the feeding cylinder 10 be can be recycled, improve cooling effect simultaneously, accelerate to reduce the speed of feeding cylinder 10 temperature.The sealing part abrasion repair and replacement of swivel joint 1 are simple and easy, need not purchase new product again, save the cost of extruder applying unit greatly.Coolant inlet pipe 2 and cooling fluid efferent duct 3 are installed on the medium input port and the medium delivery outlet of swivel joint 1 respectively, control valve 4 is a tap, coolant inlet pipe 2 is connected with control valve 4, is used to control the cooling fluid break-make of coolant inlet pipe 2 and cooling fluid efferent duct 3.The used cooling fluid of the utility model is generally water, also can be the cooling fluid of other type.Coolant inlet pipe 2 and cooling fluid efferent duct 3 adopt flexible pipe, have alleviated the load of swivel joint 1 greatly, effectively prolong the service life of swivel joint 1.
Claims (4)
