Description

Plastic double-walled corrugated pipe enlarging pick-up unit

Technical field

The utility model relates to a kind of plastic double-walled corrugated pipe enlarging pick-up unit, is mainly used in the automatic control of plastic double-walled corrugated pipe production line, particularly as the main detection control apparatus of plastic double-walled corrugated pipe tapping machine.

Background technology

Current in the production run of plastic double-walled corrugated pipe flared section, mainly be to adopt detection to produce the method for the make-up machine master motor travelling speed of corrugated tube, as detecting the important means that meter is long and supply purposes such as other device synchronization controls of production line.But owing to after each ripple cooling of corrugated tube certain amount of contraction is arranged, and shrinkage factor changes bigger under different production statuses, accurately hold with control comparatively difficult, after producing one section scale, a certain amount of cumulative errors always appear, cause control automatically very inaccurate, need manual intervention often, revise the malfunction that causes by cumulative errors.Production run do not need fully can not really accomplish the artificial robotization that participates in.Can think that the accurate detection of plastic double-walled corrugated pipe flared section is never solved at present well with the long problem of detection meter.

The utility model content: the purpose of this utility model is to overcome the deficiencies in the prior art, providing a kind of is installed on the plastic double-walled corrugated pipe production line, can be accurately, the device in synchronous detection speed of production and enlarging district stably, tubing vibrations, the contraction that can get rid of effectively in the production run are disturbed, accurately carry out speed of production detection and flared section and detect, for equipment such as tubing fixed length cutting, full-automatic perforate provide controlled variable accurately.

For realizing above-mentioned technical purpose, the utility model has adopted following technical scheme: this plastic double-walled corrugated pipe enlarging pick-up unit, shape such as four-bar mechanism parallel up and down between the seat board double link with activity connect, and be provided with up and down seat board apart from adjusting mechanism at seat board homonymy one end up and down, the upper base plate middle part is provided with vertical screw mandrel, screw mandrel can move up and down and lock in the support bracket fastened circular hole on being located at body by nut, one end of following seat board is provided with speed detector, and the other end is provided with the device of issuing an order.Seat board apart from adjusting mechanism is up and down, vertically is fixed on down on the seat board and passes the nut that is provided with nut successively, is pressed on the spring of upper base plate lower surface and is pressed on the upper base plate upper surface on the screw mandrel of upper base plate strip hole; Speed detector is, a pair of gear that cog belt connects, this cog belt lower limb are lower than the lower limb of seat board down, and the rotating shaft of a gear links to each other with the scrambler that is fixed on down the seat board opposite side, and the rotating shaft of another gear is an eccentric structure; The device of issuing an order is, the runner that has torsion spring is provided with the bar of issuing an order, and the positive stop and the limit switch of the bar both sides of issuing an order, and the wheel rim of this runner is lower than the lower limb of seat board down and is higher than the lower limb of cog belt.The screw mandrel at described upper base plate middle part vertically has long gathering sill.Described cog belt is a rubber strip, or skin is a rubber strip at least.

Adopt after such structure, the utility model will reliably and stably contact with tested corrugated tube, can get rid of interference such as tubing vibrations in the production run, contraction effectively, can on-line synchronous detect speed of production and flared section, for support equipments such as tubing fixed length cutting, full-automatic perforate provide parameter accurately such as speed and length, make the plastics both arms corrugated tube of band flared section not needing fully really realize the automation process of manually participating in process of production.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.With reference to Fig. 1 Fig. 4, have a circular hole on the fixed support 1 of corrugated tube tapping machine, leading screw 2 vertically passes this circular hole, the nut 4 of rotating band handle, screw mandrel 2 is moved up and down along this circular hole, thereby the size according to the corrugated tube caliber of being processed is adjusted its upper-lower position, makes the utility model adjust its contact pressure applicable to the double-wall corrugated pipe that detects all size and according to actual conditions.Lock-screw 5 is compressed into the long gathering sill 3 on the screw mandrel 2, can avoid leading screw 2 to cause deviation because of rotation in the course of the work screw mandrel 2 lockings.The upper base plate 6 of strip is connected to one with an end of leading screw 2, and links with following seat board 8 by the double link 7 that flexibly connects.Screw mandrel 9 one ends are fixed on down on the seat board 8, and the other end passes the strip hole 10 on the upper base plate 6, can control the degree of tilt of double link 7 by adjusting nut 11, thereby adjust the distance between the seat board up and down.And by adjusting nut 12, the pressure of control compression spring 13 can guarantee that cog belt 18 closely contacts non-slip with corrugated tube.Back of the body cap 14 and 15 is locked two adjustment nuts 11 and 12 up and down respectively.Gear 16 and 17 is installed in down an end of seat board 8, connects its outer circumference surface with cog belt 18, and the cog belt material is a rubber, or skin contains rubber at least.. it is big with corrugated tube surface of contact friction force adopting the reason of rubber material, can not lose the measurement pulse because of skidding.The lower limb of cog belt is lower than the lower limb of seat board down.

With reference to Fig. 2 Fig. 3, the rotation of gear 17 is delivered on the axle 20 by flat key 19, drive the scrambler 23 that is fixed on down seat board 8 opposite sides with mounting bracket 24 and screw 25 by flexible clutch 21 and trip bolt 22 again, make scrambler 23 main axis rotation not broken hair go out pulse, paired pulses is handled metrical informations such as the speed that can obtain, distance, provide and detect meter length, for processing step such as tubing fixed length cutting, the full-automatic perforate etc. that need synchro control on the production line provide controlled variable accurately.Gear 16 is installed on the excentric shaft 26, and adjusting this excentric shaft can swelling cog belt 18.

With reference to Fig. 1 Fig. 2; the device of issuing an order is used to detect the enlarging district; runner 27 is installed in down the other end of seat board 8; the wheel rim of this runner is lower than the lower limb of following seat board and is higher than the lower limb of cog belt; this runner also is provided with torsion spring 31; the high-low limit position that the bar 28 of issuing an order on the runner 27 rotates is limited by two positive stops 29, and they are used to determine that the original position of the bar of issuing an order is spacing with protection..When the flared section of corrugated tube was run into runner when corrugated tube advances, runner 29 overcame the moment of torsion rotation of torsion spring 31, and the bar 28 of issuing an order that is fixed on the runner 27 rotates, and when arriving the limes superiors position, limit switch 30 sends instruction, and expression has detected flared section.When the flared section of corrugated tube finishes, torsion spring 31 gives runner 27 enough screen resiliences, and it is resetted rapidly.Limit switch 30 sets back, and the expression flared section is passed through.
