Description

Technical Field

[0001] The present invention belongs to the technical field of coiling machines, and relates to a drum and a coiling machine with a supporting device resistant to axial impact. Background Art

[0002] The axial positioning of the coiling machine drum usually adopts a plug-in plate structure. However, due to the telescopic and reciprocating movements of the drum during production, the fixed plug plate cannot resist the axial impact force of the drum and is often squeezed and worn, eventually causing the cooperation size between the positioning mechanisms to gradually increase, resulting in a large axial displacement of the drum body in the axial direction during production. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a drum and a coiling machine with an external support device to prevent the axial impact force generated during the production process of the drum from damaging the axial limit mechanism of the drum.

[0004] To achieve the above purpose, the present invention provides a drum with an external support device. The external support device is arranged at the end of the drum and includes an external support bearing seat and a bearing arranged in the external support bearing seat. The drum is arranged in the bearing. The external support bearing seat includes an external support bearing seat end cover arranged at the end face of the bearing. The bearing and the external support bearing seat end cover are in clearance fit; at least one spring is arranged axially along the bearing between the external support bearing seat end cover and the bearing.

[0005] Optionally, a bearing installation hole is provided on the external support bearing seat, and the bearing is installed in the bearing installation hole.

[0006] Optionally, the drum is inserted into the bearing. The external support bearing seat end cover includes a bearing seat front end cover close to the end of the drum and a bearing seat rear end cover far from the end of the drum. The bearing seat front end cover and the bearing seat rear end cover are fixedly connected.

[0007] Optionally, the bearing seat front end cover and the bearing seat rear end cover are connected by bolts.

[0008] Optionally, a plurality of springs are provided, and the plurality of springs are arranged between the bearing seat front end cover and the bearing.

[0009] Optionally, the bearing includes a bearing inner ring, a bearing outer ring, and rollers. The rollers are embedded between the bearing inner ring and the bearing outer ring.

[0010] Optionally, a plurality of springs are provided, and the plurality of springs are arranged between the external support bearing seat end cover and the bearing outer ring.

[0011] Optionally, a plurality of springs are provided, and the plurality of springs are evenly distributed circumferentially along the bearing between the external support bearing seat end cover and the bearing.

[0012] Optionally, a bearing end cover is provided on the end face of the bearing close to the end of the reel, and a bearing positioning ring is provided on the end face of the bearing away from the end of the reel.

[0013] The present invention also provides a coiler, which includes the aforementioned reel with an external support device.

[0014] The beneficial effects of the present invention are as follows:

[0015] The present invention uses an external support bearing housing to axially position the reel, and a spring is provided in the gap between the bearing and the external support bearing housing, so that after each unwinding of the reel, the bearing can rebound under the compressive elastic force of the spring, thereby maintaining the sliding gap between the bearing and the external support bearing housing, effectively avoiding the extrusion of the external support bearing due to the axial displacement of the reel body, and improving the service life of the external support bearing. In addition, the external support bearing housing device provided by the present invention can be improved on the basis of the original external support bearing housing, without the need to purchase new spare parts, and can improve production efficiency and production results without increasing production costs.
