In other embodiments, the pressure adjusting member is connected to both the first fixing bracket and the second fixing bracket to directly adjust the distance between the first fixing bracket and the second fixing bracket.

Wherein, the pressure adjusting member 110 is a pressure adjusting nut, a spring is arranged in the pressure adjusting member, and the pressure value of the driven roller 250 is adjusted by the spring; the spring can be conveniently replaced according to different products, and the universality of the tubular objects with various specifications is realized.

The first fixing seat 70 of the present embodiment has a structure similar to that of the second fixing seat 80, and is not described herein.

Through the demoulding machine, the rapid demoulding of the tubular object can be improved, but in the field of 3C electronic products, the irregular tubular object, namely the special-shaped pipe, is widely applied, and the requirements on the forming size precision and the surface roughness of the special-shaped pipe are higher.

To achieve rapid demolding of the profiled tube, the roll loosening apparatus 20 of the present embodiment further includes an adjusting rod 130, and the adjusting rod 130 is connected to the first fixing bracket 72 and is used for adjusting a relative angle between the first fixing bracket 72 and the tubular member 260 so as to adjust a contact surface between the driven rolling wheel 250 and the tubular member 260.

Specifically, the fixing frame 71 is provided with a through hole (not shown), and one end of the adjusting lever 130 is connected to the first fixing bracket 72 through the through hole.

In the embodiment, by adjusting the contact surface between the driven rolling wheel 250 and the tubular object 260, rolling of the surfaces of each part of the special pipe can be satisfied, and rapid demoulding of the special pipe can be realized.

In other embodiments, the contact surfaces of the driven rollers and the tubular object on both sides of the accommodating chamber 230 can be adjusted by two adjusting rods.

Optionally, the roll loosening device 20 of the present embodiment further includes a guide post 140, and the guide post 140 passes through the fixing frame 71 and the second fixing bracket 73 and is located at a side of the driven roller 250 to limit the driven roller 250.

The present embodiment is provided with two guide posts 140 for limiting the driven roller 250 from both sides of the driven roller 250, respectively.

A guide post may also be provided for the drive roller 240.

In another embodiment, the stripper 10 further includes a housing 150, the housing 150 being housed over the platen 60; the roll loosening device 20 and the driving device 30, except for the motor 310, are disposed on the platen 60 in other components and are located in the housing 150.

In the embodiment, the structure of the roll loosening device 20 and the like is subjected to dust prevention, water prevention and the like through the shell 150; through holes (not shown) corresponding to the inlet pipe 210 and the outlet pipe 220 are respectively formed on two sides of the housing 150, so that the tubular object 260 can be conveniently moved in and out.

In the above embodiment, the mechanical tubes are fed into the accommodating cavity from the tube inlet, the mechanical tubes are clamped by the first pair of driving rollers and then continuously roll forward for feeding, and then the mechanical tubes pass through the three pairs of driven rollers, wherein the clamping direction of each pair of driven rollers is adjustable; the forward power is provided by 3 pairs of driving rollers, and the direction periodically-changed clamping force is provided by 9 pairs of driven rollers on the surface of the special pipe. The pressure of the driving roller and the pressure of the driven roller are from the spring in the pressure adjusting nut, and the pressure applied to the surface of the special pipe can be conveniently adjusted by screwing the nut; after the mechanical tubes are subjected to periodic rolling action of the driving roller and the driven roller, the surface concentrated stress begins to disperse and release, so that the inner mold core is separated from the inner surface of the mechanical tubes.

In contrast to the prior art, the stripper of the embodiment of the present application is used for stripping a tubular object, and the stripper includes: the rolling loosening device is used for rolling the surface of the tubular object so as to separate the inner mold core in the tubular object from the inner surface of the tubular object; and the driving device is connected with the rolling and loosening device and is used for driving the rolling and loosening device to work. The embodiment of the application rolls through the roll-loosening device to the surface of the tubular object, so that the stress on the surface of the tubular object is released, the inner mold core of the tubular object is separated from the inner surface of the tubular object, the inner mold core can be easily pulled out of the tubular object, the demolding efficiency of the tubular object can be improved, and the tubular object cannot be damaged.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
