Description

Technical Field

[0001] The invention relates to the field of mechanical technology, in particular to a tensioning force regulating device. Background Art

[0002] At present, there are two main structures for tensioning the textile belt in the ironing machine. One is to use an adjusting bolt to adjust the position of the T-belt seat bearing to achieve the purpose of tensioning the textile belt. However, this structure cannot respond in time when the length of the textile belt changes and needs to be adjusted manually, otherwise it will be too loose or too tight. The other is to add a cylinder between the adjusting bolt and the bearing, and use the cylinder to provide tensioning force. This structure is more expensive and increases the complexity of the system. Summary of the invention

A spring is sleeved on the second adjusting bolt, one end of the spring is against the adjusting plate, and the other end of the spring is against the T-type belt seat bearing.

[0009] When the length of the textile belt changes, the length of the spring in the structure of the present invention will change accordingly, so that the textile belt is always in a taut state. This avoids the cumbersome operation of manual adjustment when the length of the textile belt changes in the original structure. Compared with cylinder adjustment, the cost of this structure is lower, and no external power is required, thereby improving the stability of the overall system.

[0010] Further preferably, the adjustment plate comprises a base plate portion, the base plate portion is arranged closely to the frame, and the left and right ends of the base plate portion are respectively connected with a left flange and a right flange which are bent;

[0019] The outermost plates in the upper pad and the lower pad are both provided with mutually adjacent extension parts, and the extension parts are slidably connected with the T-shaped seat bearing.

[0020] Easy to assemble.

[0021] Further preferably, the two ends of the spring are respectively a first concentric block and a second concentric block abutting against each other;

[0022] The first concentric block is welded and fixed on the left flange;

[0023] The second concentric block is pressed against the T-type seat bearing by a spring force;

[0024] The T-shaped seat bearing is embedded with a second locking nut threadedly connected to the second adjusting bolt.

[0026] Further preferably, the spring provides force to separate the T-type belt seat bearing from the adjusting plate, and the T-type belt seat bearing is constantly subjected to the force from the spring, and the force acts on the roller shaft to continuously tension the textile belt.

[0027] Beneficial effects: In addition to using the first adjusting bolt to adjust the position of the T-type belt seat bearing, the present invention also designs a set of structures to adjust the position of the adjusting plate. When the length of the textile belt changes, the length of the spring will change accordingly, so that the textile belt is always in a taut state.
