Description
Technical field
The utility model is related to engineering plastics production equipment field, especially a kind of modified polyamide, polyphenylene oxide alloy work
Engineering plastics are granulated check rod device.
Background technology
In the prior art, in plastics-production process, extruder enters bosh cooling after squeezing out material strip, after cooling then
It is delivered in granulating mechanism by check rod device；Existing check rod device is typically all to use upper and lower two pressure rollers by material strip pressure
Firmly, it then rotates and conveys it forward, then during this, since material strip distance cooling in sink is longer, and resistance is larger,
Required tractive force is big, and larger pressure is may require that when being pushed down using pressure roller, be easy to cause situations such as material strip deforms, shadow
Ring the normal operation of equipment.
Utility model content
There is provided purpose of the utility model is to solve the deficiency of above-mentioned technology a kind of simple in structure, hauling ability is steady
Fixed modified polyamide, polyphenylene oxide alloy engineering plastics are granulated check rod device.
In order to achieve the above object, a kind of modified polyamide designed by the utility model, polyphenylene oxide alloy engineering plastics
It is granulated check rod device, including carry-over pinch rolls and limit roller group, the both ends of the carry-over pinch rolls are arranged on axle bed, wherein one end is led
It is sequentially connected between pick-up roll and No.1 motor, what is be spaced on carry-over pinch rolls is fixedly installed multiple traction wheels, each traction wheel
Peripheral surface on be arranged fluted, in the peripheral surface of traction wheel twist, the section of groove is arc to groove, each
Groove on traction wheel is at least a circle；The limit roller group is arranged in carry-over pinch rolls side, and is located at plastic strip conveying side
To front, the axial direction for limiting roller group is parallel with the axial direction of carry-over pinch rolls；Limit roller group is made of two limit rollers, in limit roller group
One end be provided with No. two motor, plastic strip is passed through between two limit rollers of limit roller group, and limit roller is pressed
It holds；The linear velocity that traction wheel conveys plastic strip is identical as the limit roller group conveying linear velocity of plastic strip.
Above-mentioned technical proposal, in actual use, by plastic strip after cooling around the groove being located on traction wheel
It is interior, then enter back into limit roller group inside pressed, due to when plastic strip is around the groove for being located at traction wheel with traction wheel it
Between will produce larger frictional force, to can avoid limit roller group excessive pressure is provided and plastic strip is caused to deform；In addition
In distraction procedure, it is only necessary to which the hauling speed of carry-over pinch rolls and limit roller is consistent, and the two synchronizes check rod, ensure that operation
Stability, check rod is more smooth, and situations such as avoiding causing deformation to plastic strip, it is stronger that equipment runs duration.
The section of groove on traction wheel is the half in plastic strip section.The section for being designed as groove of the structure is half
Circular configuration, diameter is consistent with the diameter of plastic strip or diameter slightly larger than plastic strip, it is ensured that plastic strip with it is recessed
The fitment stability of slot, frictional force are big.
A kind of obtained modified polyamide of the utility model, polyphenylene oxide alloy engineering plastics are granulated check rod device, lead to
Rational structure design is crossed, realizes that traction wheel generates larger chucking power to material strip and during check rod, limits roller group and lead
Pick-up roll collective effect so that check rod effect stability, reliably.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below by embodiment combination attached drawing, the utility model will be further described.
Embodiment 1：
As shown in Figure 1, a kind of modified polyamide of the present embodiment description, polyphenylene oxide alloy engineering plastics are granulated check rod dress
It sets, including carry-over pinch rolls 1 and limit roller group 6, the both ends of the carry-over pinch rolls 1 are arranged on axle bed 2, wherein the carry-over pinch rolls 1 of one end
It is sequentially connected between No.1 motor 3, what is be spaced on carry-over pinch rolls 1 is fixedly installed multiple traction wheels 4, each traction wheel 4
Peripheral surface on be arranged fluted 5, in the peripheral surface of traction wheel 4 twist, the section of groove 5 is arc to groove 5,
Groove 5 on each traction wheel 4 is at least a circle；The limit roller group 6 is arranged in 1 side of carry-over pinch rolls, and is located at plastics material
The front of 7 conveying direction of item, the axial direction for limiting roller group 6 are parallel with the axial direction of carry-over pinch rolls 1；Roller group 6 is limited by two limit roller structures
At being provided with No. two motor 8 in one end of limit roller group 6, plastic strip 7 is worn between two limit rollers of limit roller group 6
It crosses, and limit roller is pressed；Traction wheel 4 conveys the line of the linear velocity and the limit conveying plastic strip 7 of roller group 6 of plastic strip 7
Speed is identical.
The section of groove 5 on traction wheel 4 is the half in 7 section of plastic strip.
