Figure 2 This is a front view of the first embodiment of the utility model. Figure 3 It is a partial structural schematic diagram of the first embodiment of the utility model.

[0019] The utility model provides a mandrel extractor, comprising a frame 101, a main control cabinet 102, an operating cabinet 103, a working frame 104, an upper traction group, a lower traction group, a first bracket 105 and a mandrel baffle 106, wherein the main control cabinet 102 and the operating cabinet 103 are both arranged on the frame 101, the working frame 104 is fixedly connected to the frame 101, the lower traction group is mounted on the frame 101, the upper traction group is mounted on the working frame 104, the first bracket 105 is fixedly connected to the frame 101, the mandrel baffle 106 is movably connected to the first bracket 105, and the mandrel baffle 106 is provided with a through hole 118;

[0020] The upper traction group includes two cylinders 107, two connecting plates 108 and a first traction unit. The two cylinders 107 are installed on the working frame 104. The output ends of the two cylinders 107 are fixedly connected to the corresponding connecting plates 108 respectively. The first traction unit is fixedly connected to the two connecting plates 108.

[0021] The lower traction group includes two screw elevators 109 , two support members 110 and a second traction unit. The two screw elevators 109 are both arranged on the frame 101 , the two support members 110 are respectively arranged on the corresponding screw elevators 109 , and the second traction unit is fixedly connected to the two support members 110 .

[0022] With respect to this specific embodiment, during specific use, after the hose is formed, when the mandrel needs to be pulled out, first, the tube head of the hose after the end is cut off is removed to expose the mandrel, and then the mandrel is passed through the through hole 118. At this time, a part of the mandrel is placed between the upper traction group and the lower traction group, and the hose end is against the mandrel baffle 106. The two cylinders 107 and the two screw elevators 109 are started, and the two cylinders 107 drive the first traction unit to move downward, and the two screw elevators 109 drive the second traction unit to move upward, so that the first traction unit and the second traction unit clamp the mandrel, and then the first traction unit and the second traction unit are started. The first traction unit and the second traction unit work to drive the mandrel to move. At this time, since the hose end is blocked by the mandrel baffle 106, the mandrel moves in the hose until it is pulled out. In this way, it is easy to pull out the mandrel in the formed hose.

[0023] The mandrel extractor further comprises a second bracket 111 and a tube head baffle 112 . The second bracket 111 is fixedly connected to the frame 101 . The tube head baffle 112 is detachably arranged on the second bracket 111 . A card slot 119 is arranged on the tube head baffle 112 .

[0024] With respect to this specific embodiment, when it is inconvenient to remove the tube head, it is only necessary to cut an annular opening on the hose, place the hose on the second bracket 111, and insert the slot 119 on the tube head baffle 112 into the cut annular opening, and then clamp the hose by the upper traction group and the lower traction group and pull it toward the mandrel baffle 106. At this time, the hose moves, and the tube head on the side of the tube head baffle 112 away from the mandrel baffle 106 is blocked by the tube head baffle 112 and detached from the mandrel, so that the tube head can be removed, and then the mandrel can be pulled out.

[0025] Secondly, the first traction unit and the second traction unit each include a mounting frame 115, a servo motor 116 and a transmission belt 117, wherein one of the mounting frames 115 is fixedly connected to the two connecting plates 108, and the other mounting frame 115 is fixedly connected to the two supporting members 110, and the transmission belt 117 is arranged on the corresponding mounting frame 115, and the servo motor 116 is installed on the corresponding mounting frame 115, and the servo motor 116 is used to drive the corresponding transmission belt 117.

[0026] According to this specific embodiment, the two cylinders 107 and the two screw elevators 109 drive the two mounting frames 115 to move toward each other, so that the two transmission belts 117 are clamped on the core rod or hose, and the two servo motors 116 are started. The two servo motors 116 drive the two transmission belts 117 to move and transport the core rod or hose.

[0027] Meanwhile, the core rod extractor further comprises an extracting member 113 , and the extracting member 113 is fixedly connected to the upper end of the tube head baffle 112 .

[0028] According to this specific embodiment, by providing the extraction member 113 , the tube head baffle 112 can be installed and removed more conveniently.

[0029] In addition, the mandrel extractor further includes a storage platform 114 , and the storage platform 114 is disposed on the frame 101 .

[0030] According to this specific implementation, the storage table 114 is convenient for workers to place work supplies.

[0031] When using a mandrel extractor according to the present embodiment, after the hose is formed, when the mandrel needs to be pulled out, the hose head after the end is cut off is firstly removed to expose the mandrel, and then the mandrel is passed through the through hole 118. At this time, a part of the mandrel is placed between the upper traction group and the lower traction group, and the hose end is against the mandrel baffle 106. The two cylinders 107 and the two screw elevators 109 are started, and the two cylinders 107 drive the first traction unit to move downward, and the two screw elevators 109 drive the second traction unit to move upward, so that the first traction unit and the second traction unit clamp the mandrel, and then the first traction unit and the second traction unit are started. The first traction unit and the second traction unit work to drive the mandrel to move. At this time, since the hose end is blocked by the mandrel baffle 106, the mandrel moves in the hose until it is pulled out, so that the mandrel in the formed hose can be easily pulled out in this way;

[0032] When it is inconvenient to remove the tube head, it is only necessary to cut an annular opening on the hose, place the hose on the second bracket 111, and insert the slot 119 on the tube head baffle 112 into the cut annular opening. Then, the hose is clamped by the upper traction group and the lower traction group and pulled toward the mandrel baffle 106. At this time, the hose moves, and the tube head on the side of the tube head baffle 112 away from the mandrel baffle 106 is blocked by the tube head baffle 112 and detached from the mandrel, so that the tube head can be removed, and then the mandrel can be pulled out.
