Description

Technical Field

[0001] The utility model belongs to the technical field of gas pipe production, and particularly relates to a cutting and winding device of a metal pipe plastic coating machine. Background Technique

[0002] A gas pipe is a special pipe for transporting combustible gas, and it uses a metal gas pipe hose to replace the traditional buckle-type rubber hose, which can solve the defects of easy falling off, easy aging, easy insect bite, and short service life of the rubber hose. During the processing of the gas pipe, the metal pipe needs to be plastic-coated by a metal pipe plastic coating machine to form the gas pipe.

[0003] At present, a Chinese patent with the publication number CN102922712A and the publication date of February 13, 2013 discloses a medium and high frequency induction heating type high-speed metal pipe plastic coating machine, which is composed of a pipe feeding station, a pinch roller device driven by a feeding roller speed feedback and a stepping motor, a medium and high frequency induction preheating device, an infrared temperature measuring device, a plastic extruder, a cooling device with flow control, a pipe discharging station, and a control system.

[0004] This medium and high frequency induction heating type high-speed metal pipe plastic coating machine completes the steel pipe plastic coating process at the extrusion outlet of the plastic extruder, and then cools it to an appropriate temperature through the cooling device to form the final product; finally, it can be wound on the winding disc through the vertical shaft traction roller and the horizontal shaft roller at the pipe discharging station.

[0005] Among them, after a roll of gas pipe is wound on the winding disc, the operator needs to first cut the transported gas pipe with scissors, and then unload the wound gas pipe from the winding disc. In this way, the gas pipe roll needs to be unloaded from the winding disc every time a roll of gas pipe is wound, which will eventually make the entire winding work time-consuming and laborious. Content of the Utility Model

[0006] The purpose of the utility model is to provide a cutting and winding device of a metal pipe plastic coating machine, which is beneficial to efficiently winding the gas pipe roll.

[0007] The above technical object of the present utility model is achieved through the following technical solutions: A cutting and winding device for a metal pipe plastic coating machine, including a bracket, a winding disc located on the upper side of the bracket, a rotating shaft fixed at the center of the winding disc, and a driving member arranged on the bracket and used to drive the rotating shaft to rotate. The rotating shaft extends to a position above the winding disc. A fixed disc is arranged at the upper end of the rotating shaft. A plurality of guiding arms are arranged on the circumferential side of the fixed disc and are evenly spaced along the circumferential side of the fixed disc. A plurality of through holes are opened on the circumferential side of the fixed disc and are evenly spaced along the circumferential side of the fixed disc. Connecting ears are arranged on both sides of the through holes on the upper surface of the fixed disc. A support rod for winding the gas pipe is arranged at the position of the through hole on the fixed disc. A chute with a "convex" cross-section is arranged on both sides of the support rod. A fixed shaft penetrating into the chute is arranged on the connecting ear. A guide wheel embedded in the inner side of the chute is arranged at one end of the fixed shaft away from the connecting ear. A winding guide post extending in the vertically upward direction is arranged at the upper end of the guiding arm between adjacent support rods.

[0008] A further setting of the present utility model is: A positioning sleeve for the lower end of the support rod to be embedded when in a vertical state is arranged below the through hole on the winding disc.

[0009] A further setting of the present utility model is: Elastic buckles in a C shape for the end heads of the gas pipe to be embedded are arranged on the outer circumferential wall of the winding disc and at the end of the support rod.

[0010] A further setting of the present utility model is: Guide portions extending obliquely outwards are arranged at both ends of the elastic buckle.

[0011] A further setting of the present utility model is: A plurality of elastic buckles are arranged on the circumferential side of the winding disc and are evenly spaced along the circumferential side of the winding disc.

[0012] A further setting of the present utility model is: The driving member includes a driving motor arranged on the lower side of the bracket, a driving wheel arranged on the output shaft of the driving motor, a driven wheel arranged at the lower end of the rotating shaft, and a transmission belt arranged between the driving wheel and the driven wheel.

[0013] A further setting of the present utility model is: A scissor box with scissors stored inside is arranged at the side of the bracket.

[0014] In summary, the present utility model has the following beneficial effects:

[0015] 1. When winding the gas pipe transmitted by the support, the gas pipe is first wound on the winding disc, and multiple guiding arms are used to position the winding of the gas pipe; after a roll of the gas pipe on the winding disc is wound, the operator cuts the gas pipe, and then the gas pipe can be wound on multiple support rods above the winding disc, and the winding guide post is used to position the winding of the gas pipe; after a roll of the gas pipe on the support rod is wound, there will be two gas pipe rolls, one on top and one on the bottom, left on the support at this time.

[0016] Subsequently, the operator first removes the gas pipe roll on the support rod, then swings the support rod upward so that the support rod is in a vertical position, and then the support rod can slide down along the guide wheel into the through hole, so that the support rod remains in a vertical state in the through hole; then the gas pipe roll on the winding disc can be quickly removed, so that the removal of the two gas pipe rolls, one on top and one on the bottom, can be completed at one time; at this time, the support can simultaneously wind two rolls of gas pipe rolls, and finally it is beneficial to efficiently wind the gas pipe rolls.

[0017] 2. When the support rod slides down along the guide wheel into the through hole, the lower end of the support rod can be embedded in the positioning sleeve, and the positioning sleeve can play a role in positioning the lower end of the support rod, and finally it is beneficial to ensure that the support rod always remains in a vertical state and avoid interference of the support rod with the removal of the lower gas pipe roll.

[0018] 3. When winding the gas pipe on the winding disc and the support rod, the end of the gas pipe can be embedded in the elastic buckle, and the elastic buckle locks the end of the gas pipe, which is beneficial to the stable winding of the gas pipe on the winding disc and the support rod.

[0019] 4. By using the guiding parts provided at both ends of the elastic buckle and extending obliquely outward, the guiding parts can play a guiding role and are beneficial to the smooth embedding of the end of the gas pipe in the elastic buckle.

[0020] 5. By using multiple elastic buckles provided on the periphery of the winding disc and evenly spaced along the periphery of the winding disc, the end of the gas pipe can be embedded in any one of the elastic buckles during the rotation of the winding disc, and finally it is beneficial to quickly lock the end of the gas pipe on the periphery of the winding disc.

[0021] 6. After the driving motor is started, the driving wheel, the driven wheel and the transmission belt are used to drive the rotating shaft to rotate.

[0022] 7. The scissors box on the support can be used for fixed-point storage of scissors, thus avoiding the situation that the scissors are lost and the transmitted gas pipe cannot be cut in time. Description of the Drawings
