Description
Technical field
The present invention relates to a kind of device of plastic processing, especially a kind of screw tube of plastic extruding machine device.
Background technology
Plastic extruder is one of capital equipment that must use in the chemical plastic manufacturing enterprise, but because chemical plastic is required various in style in the existing society, often need the frequent various processing of plastic temperature that change---promptly change the extruding machine barrel temperature, satisfy the requirement of each product processes with this, this just needs extruding machine barrel heating and cooling system reliable.
At present, the cooling water pipe in the extruding machine barrel device commonly used, barrel, it is wrapped in the inside by barrel, is an integral body, can not dredge separately.When long-time production, the water pipe in the barrel is stopped up by incrustation scale easily, does not have cool effect, causes the performance of product and color defective, has only and utilizes a kind of chemical detergent of high-strength pressure handle to compress into the row cleaning.As a rule, be difficult to reach the purpose that thorough snaking is got through water pipe, need unload barrel and just can clear up.Many times also because of not getting through pipeline, whole barrel has just been scrapped.
In addition, extruding machine barrel device commonly used, the temperature detecting head of heating system has only one, so whether can only survey a heat block normal, causes temperature instability in the barrel, produces scrap products.
Just because of the defective on the said structure, therefore extruding machine barrel device in the market has following shortcoming:
1, the barrel cooling system stops up, and temperature raises, and produces scrap products.
2, compress into a kind of chemical agent of high-strength pressure handle and carry out cleaning and dredging, dangerous and be unfavorable for operator ' s health;
3, the serious obstruction of barrel can't be dredged, and causes the barrel wasting of resources and maintenance cost to strengthen
4, single heating temperature control detecting head can't accurately be measured whether operate as normal of two heat blocks
5, single heat block heating can cause the extruder wearing and tearing to strengthen the life-span reduction, and produces scrap products.
Therefore, how to allow solve the problems referred to above that the screw tube of plastic extruding machine device exists, just become the problem that the industry reduced production costs, improved service life of equipment.
Summary of the invention
Purpose of the present invention: aim to provide a kind of can be safely, efficient running, be convenient to the novel barrel device of safeguarding again.
This screw tube of plastic extruding machine device, comprise barrel, cooling water pipe, temperature probe, heat block and splayed alloy cover etc., cooling water pipe wherein is arranged in the barrel, heat block is arranged on the barrel body, temperature probe and splayed alloy are set on the barrel inner chamber, it is characterized in that: described cooling water pipe is the frame type connecting pipe that is connected to form by single straight tube, and the two ends of each root single tube are provided with plug; Described temperature probe its underpart is splayed, and is suspended at splayed alloy cover top.
Described cooling water pipe, one group of body that its front and back are adjacent connects by one section in the preposition or rearmounted frame type pipe tilting single tube.
Described cooling water pipe, the connecting portion of its each group frame type pipe is positioned at outside the cylindrical shell of barrel.
Described cooling water pipe, its tube chamber cross section is circle or rectangle.
This screw tube of plastic extruding machine device according to above technical scheme proposition, because the cooling water pipe that will be located in the cylindrical shell connects and composes with the straight tube that two ends are provided with plug, in case therefore produce the incrustation scale clogging in the body, just can unload the plug at two ends, carry out block clearing with physical method and handle.Simultaneously, because the two temperature probes that adopt Y-shaped to be provided with, for realizing that the timing monitoring of the fast duty of upper and lower heating has been created reliable assurance.

The specific embodiment
This screw tube of plastic extruding machine device as shown in the figure, it is inventive improvements to existing screw tube of plastic extruding machine device, it comprises barrel 1, cooling water pipe 5, temperature probe 8, heat block 9,10 and splayed alloy cover 3, cooling water pipe 5 wherein is arranged in the barrel 1, heat block 9,10 is arranged on the barrel body, temperature probe 8 and splayed alloy cover 3 are arranged on barrel 1 inner chamber, it is characterized in that: described cooling water pipe 5 is the frame type connecting pipes that connected to form by single straight tube, and the two ends of each root single tube are provided with plug 6; Described temperature probe 8 its underparts are splayed, and are suspended at the splayed alloy and overlap 3 tops.
Described cooling water pipe 5, one group of body that its front and back are adjacent connects by one section in the preposition or rearmounted frame type pipe tilting single tube.
Described cooling water pipe 5, the connecting portion of its each group frame type pipe is positioned at outside the cylindrical shell of barrel 1.
Described temperature probe 8 is made of two temperature sensors that branch is located in the splayed bifurcated.
In actual use, cooling water pipe 5 two ends can directly get out on barrel 1, and such benefit is directly the plug of cooling water pipe to be exposed to the outside of barrel 1, are convenient to carry out snaking and handle.Simultaneously, the cooling water pipe 5 that is adopted, its cross section can be a round tube, also can be rectangular tube.
Operation principle:
Install the novel barrel of extruder by Fig. 5, during work, connect power supply, the heat block heating, when temperature reaches requirement, extruder work, when temperature raises, cooling water pipe water flowing cooling, temperature is reduced to the requirement of setting, thereby reaches temperature stabilization, two temperature control probe head apparatus, can accurately detect the working condition of two heat blocks, avoid single heat block to heat the irregular unfavorable situation of heating that is caused, further improve the stable and uniform of temperature.After long-term the use, cooling water pipe meeting fouling, water pipe attenuates, even stop up, when safeguarding mediation cooling water pipe plug 6 is pulled down, select for use the metal bar that is narrower than cooling water pipe 5 slightly directly to dredge and get final product, because of adopting straight tube not have the dead angle, a little firmly beat the metal probe and can dredge, need not medicament.Thereby reach easy mediation, easily detect the heat block working condition, temperature stabilization is even, saves cost.
Technical solution of the present invention beneficial effect and characteristics are, and are simple in structure, and working service is convenient, successful, and its advantage is:
1, adopts straight tube, no dead angle, easily dredging.
2, barrel improves service life greatly, and maintenance cost reduces.
3, the Operation and Maintenance personal security has obtained guarantee.
4, improve equipment life.
When 5, dredging, save time, laborsaving.
6, two temperature detecting head, the stable temperature control degree greatly improves.
