Description

Technical Field

[0001] This utility model relates to the field of tension control technology, specifically a tension control device for filter bag production. Background Technology

[0002] Tension control devices are core equipment used in the filter bag production process to precisely control the tension experienced by the filter bags during processes such as conveying, cutting, sewing, and heat sealing.

[0003] Patent CN220245021U discloses a tension control and adjustment device for a nonwoven fabric winding machine, including a base. A first conveyor roller is arranged on the top of the base, a second conveyor roller is arranged on one side of the first conveyor roller, and a take-up roller is arranged on one side of the second conveyor roller. An adjustment mechanism is arranged between the first and second conveyor rollers. This patent works by having the nonwoven fabric pass through the first conveyor roller, the second conveyor roller, and the adjustment roller. Then, by activating an electric telescopic rod, the mounting base is lowered, causing the roller frame at the bottom of the mounting base to move downward along the slide groove under the action of a slider. This causes the adjustment roller to gradually press against the nonwoven fabric between the first and second conveyor rollers, making it taut. This allows for more precise adjustment of the tension of the nonwoven fabric during winding, preventing slack during winding.

[0004] As shown in the above technology, ordinary equipment uses an elastic tensioning wheel. However, the elasticity of the spring is prone to aging. Excessive tension may cause the filter bag material to break or cause the filter bag to be damaged prematurely due to stress concentration during use. Insufficient tension may cause the filter bag to loosen and wrinkle. Utility Model Content

One side of the threaded block 55 is slidably connected to the surface of the vertical plate 52. A horizontal shaft 56 passes through one side of the threaded block 55, and a stabilizing plate 57 is fixedly connected to one end of the horizontal shaft 56.
