Problems solved by technology
[0003] However, the upper and lower pressing plates press the strip, and the contact surface between the upper and lower pressing plates and the strip is relatively large. During the coiling process, while the upper and lower pressing plates form tension on the strip, a large amount of heat will also be generated, which will affect part of the surface. The coating layer of the coated strip is affected, resulting in the fact that some of the coated strips cannot use the existing tension device to provide tension

Embodiment Construction
[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the protection scope of the present invention.
[0023] see figure 1 , a switchable tension device, comprising a frame 10, a first tension mechanism 20 and a second tension mechanism 30, the frame 10 is provided with a first mounting end 11 and a second mounting end 12, the first mounting end 11 is provided with a base 111 and a mounting frame 112 located above the base 111. The first tension mechanism 20 is installed on the first mounting end 11 to provide tension to the uncoated strip. The first tension mechanism 20 includes a pressing plate assembly 21 and an airbag constant pressure mechanism 22, the pressing plate assembly 21 is located on the top of the base 111, the pressing pla...

The invention discloses a switchable tension device. The switchable tension device comprises a rack, a first tension mechanism and a second tension mechanism; the rack is provided with a first mounting end and a second mounting end; the first tension mechanism is mounted at the first mounting end, is used for providing tension for belt materials with the uncoated surfaces and comprises a pressingplate assembly and an airbag constant-pressure mechanism; and the second tension mechanism is mounted at the second mounting end, is used for providing tension for belt materials with the surfaces being partially coated and comprises a movable seat, a hydraulic driving cylinder, an upper tension roller and a lower tension roller. According to the switchable tension device, through cooperation of the rack, the first tension mechanism and the second tension mechanism, the first tension mechanism and the second tension mechanism for providing the tension for the belt materials can be switched according to the texture or the material thickness of the belt materials, and using is more convenient.
Description
technical field [0001] The invention relates to the technical field of tension devices, in particular to a switchable tension device. Background technique [0002] The tension device is suitable for all kinds of metal slitting equipment, leveling and cross-cutting equipment, metal polishing equipment, supporting equipment for sheet metal pickling production line, supporting equipment for cold rolling mill, sheet metal rewinding production line and other automatic metal processing equipment, with adjustable tension The role of the winding can be neatly collected. The existing tension device only uses the upper and lower pressing plates to establish tension. The device is composed of a fixed lower pressing plate, a movable upper pressing plate and a pressing oil cylinder. When the strip passes through the upper and lower pressing plates, the upper pressing plate compresses the strip under the action of the pressing oil cylinder. , give it a set pressure, the pressure will giv...
