AI Technical Summary
这类结构的张力控制装置制造成本较高
[0014] Because the gravity-assisted tension cylinder piston pressure of the balance block assembly is balanced with the tension of the yarn bundle and the self-weight of the tension adjusting roller and the slider; when the yarn bundle from the previous process becomes disordered, causing changes in yarn bundle tension, the slider of the tension adjusting roller will slide up and down along the first slide rail and transmit the signal to the upper sprocket shaft through the upper chain. The upper sprocket shaft drives the angle transmitter to act, so that the up and down movement of the tension adjusting roller is converted into an electrical signal, thereby facilitating the automatic adjustment of the operating speed of subsequent equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to a fiber tow production equipment, specifically a tension control device for fiber tow transmission. Background Technology
[0002] Tension control devices play a crucial role in controlling product quality during filament production, preventing tangling caused by loose filaments. However, typical tension control devices use a servo motor to drive a tension roller in conjunction with a tension detector to maintain the set tension on the filament.
[0003] Alternatively, as disclosed in 202510137593.4, a tension control device in a novel motor rotor sheath winding system includes a motor rotor, a pneumatic tailstock, pneumatic grippers, a rotor drive motor, a front-end winding reciprocating motor, and a front-end winding connecting plate. All components—motor rotor, pneumatic tailstock, pneumatic grippers, rotor drive motor, front-end winding reciprocating motor, and front-end winding connecting plate—are housed within an aluminum alloy door or window. The motor rotor is positioned between the pneumatic tailstock and the pneumatic grippers. The front-end winding reciprocating motor is connected to the front-end winding connecting plate, and the rotor drive motor is connected to a belt. Tension control devices with this type of structure have higher manufacturing costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a low-cost tension control device for filament transport.
[0005] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a tension control device for filament transmission, including a frame, a mounting frame on the frame, a vertically arranged tension cylinder on the mounting frame, a slider connected to the piston rod end of the tension cylinder, a vertically arranged first slide rail on the mounting frame, the slider being slidably mounted on the first slide rail, and a tension adjusting roller on the slider for the filament to pass over from above.
[0006] The mounting frame is equipped with a pair of vertically arranged second slide rails, and the second slide rails are equipped with a balance block assembly that moves up and down. The mounting frame is equipped with an upper sprocket next to the tension cylinder. An angle transmitter is connected to the sprocket shaft of the upper sprocket. An upper chain is wound around the upper sprocket. One end of the upper chain is connected to the balance block assembly that is slidably set on the mounting frame, and the other end of the upper sprocket is connected to the slider.
[0007] The gravity-assisted tension cylinder piston pressure of the balance block assembly is balanced with the tension of the filament bundle and the self-weight of the tension adjusting roller and the slider.
[0008] As a preferred embodiment, the balance block assembly includes a sliding seat movably disposed on a second slide rail, and a plurality of balance blocks are detachably disposed on the sliding seat.
[0009] As a preferred embodiment, the mounting bracket has a lower sprocket at the bottom of the balance block, and the bottom of the balance block is connected to the slider via a lower chain that passes around the lower sprocket.
[0010] As a preferred embodiment, the tension cylinder is arranged vertically downwards.
[0011] As a preferred embodiment, the sliding seat is provided with rollers on both sides that cooperate with the second slide rail.
[0012] As a preferred embodiment, the frame is provided with guide rollers on both sides below the tension adjusting roller.
[0013] The beneficial effects of this utility model are:
[0014] Because the gravity-assisted tension cylinder piston pressure of the balance block assembly is balanced with the tension of the yarn bundle and the self-weight of the tension adjusting roller and the slider; when the yarn bundle from the previous process becomes disordered, causing changes in yarn bundle tension, the slider of the tension adjusting roller will slide up and down along the first slide rail and transmit the signal to the upper sprocket shaft through the upper chain. The upper sprocket shaft drives the angle transmitter to act, so that the up and down movement of the tension adjusting roller is converted into an electrical signal, thereby facilitating the automatic adjustment of the operating speed of subsequent equipment.
[0015] Since the balance block assembly includes a sliding seat movably mounted on the second slide rail, and several balance blocks are detachably mounted on the sliding seat, the corresponding balance blocks can be installed as needed.
[0016] Because the mounting frame has a lower sprocket at the bottom of the balance block, and the lower part of the balance block is connected to the slider by a lower chain that passes around the lower sprocket, the device runs more smoothly.
[0017] Because the sliding seat is equipped with rollers on both sides that cooperate with the second slide rail, the movement of the sliding seat is smoother.
[0018] Because guide rollers are installed on both sides below the tension adjustment roller on the frame, the cooperation between the yarn bundle and the tension adjustment roller is more reliable. Attached Figure Description
