Technical field

The utility model belongs to plastics machinery, is specifically related to a kind of tractor of extruding of plastics tubing extrusion molding process use.

Background technology

Primacord is to be made by the fiber material originally, and processing tubing is put into explosive in the tubing more earlier, processes primacord.The tractor of primacord is a track type in the prior art, clamps up and down, and tractive force is big; There is following shortcoming in it: because the primacord majority is twice or repeatedly multiple working procedure production moulding, all be to be produced by several direct labors in the production process of multiple working procedure, explosive is equipped with in the tubing the inside; In the process of tractor traction, blasting charge is squeezed in the tubing, sets off an explosion easily; Cause industrial accident, increase personnel's in the production process insecurity; Time-consuming, effort, complex procedures, trouble.

Summary of the invention

In order to overcome the problems referred to above that the prior art field exists; The purpose of the utility model is; Provide a kind of primacord to extrude five-roller traction machine; The squeeze that tubing receives when solving the tractor traction is excessive, and interior blasting charge causes industrial accident easily, and the problem of time-consuming, effort, complex procedures, trouble.

The primacord that the utility model provides is extruded five-roller traction machine; It comprises frame, PWR PLT, towing mechanism; PWR PLT comprise phonomoter, transmission shaft, drive sprocket, chain, driven sprocket, and motor is fixedly connected on the frame, and its output terminal is connected with drive sprocket; Driven sprocket is fixed on the transmission shaft, and drive sprocket, driven sprocket pass through chain engages; Towing mechanism comprises plummer block housing bearing, square seat bearing, upper roller, bottom roller; Transmission shaft is connected on the frame through plummer block housing bearing, square seat bearing fixing; Upper roller connects the top transmission shaft, and bottom roller connects the bottom transmission shaft, and upper roller, bottom roller are up and down alternately.

In order to obtain with technique effect well; It also comprises press-roller device; Press-roller device is arranged on origin or beginning upper roller, the terminal upper roller, and described press-roller device comprises stationary shaft, wheel pressing shaft, pinch roller, bearing, and stationary shaft is fixedly connected on the frame; It is sleeved on the wheel pressing shaft, and pinch roller is connected on the wheel pressing shaft through bearing fixing.

The upper roller of described towing mechanism is the concavity plain-barreled roll, and the pinch roller broadband of press-roller device notch broadband therewith equates; Bottom roller is provided with a plurality of grooves, groove innermost fillet diameter and moulding product equal diameters.

The primacord that the utility model provides is extruded five-roller traction machine, and its beneficial effect is that production rate is fast, and PM can reach more than 80 meter, is the several times of existing equipment; Rational in infrastructure, running is steady, low-loss, and noiselessness, pollution-free, dustproof and anti-explosion; Totally-enclosed, safe and reliable.

Embodiment

With reference to the accompanying drawings,, the primacord that the utility model provides is extruded five-roller traction machine, carry out detailed explanation in conjunction with an embodiment.

Embodiment

With reference to Fig. 1-Fig. 2-Fig. 3; The primacord of present embodiment is extruded five-roller traction machine, and it comprises frame, PWR PLT, towing mechanism, and PWR PLT comprise phonomoter 2, transmission shaft 5, drive sprocket 1, chain 3, driven sprocket 4; Phonomoter 2 is fixedly connected on the frame 14; Its output terminal is connected with drive sprocket 1, and driven sprocket 4 is fixed on the transmission shaft 5, and drive sprocket 1, driven sprocket 4 are through chain 3 engagements; Towing mechanism comprises plummer block housing bearing 6, square seat bearing 7, upper roller 8, bottom roller 9; Transmission shaft 5 is fixedly connected on the frame 14 through plummer block housing bearing 6, square seat bearing 7; Upper roller 8 connection top transmission shafts 5,5,3 upper rollers of bottom roller 9 connection bottom transmission shafts 8 form the upper roller group; 2 bottom rollers 9 form the bottom roller group, and roller set alternately up and down.

It also comprises press-roller device; Press-roller device is arranged on origin or beginning upper roller 8, the terminal upper roller 8; Described press-roller device comprises stationary shaft 10, wheel pressing shaft 11, pinch roller 12, bearing 13; Stationary shaft 10 is fixedly connected on the frame 14, and it is sleeved on the wheel pressing shaft 11, and pinch roller 12 is fixedly connected on the wheel pressing shaft 11 through bearing 13.
