Description

Technical Field

[0001] This utility model relates to the field of traction equipment technology, and in particular to a fully automatic double roller traction machine with adjustable speed. Background Technology

[0002] The traction machine needs to transmit materials during operation. However, without a stabilizing device, the materials will sway from side to side during operation. This swaying causes unstable tension during processing and conveying. Unstable tension will lead to a decline in the overall production process of the materials and will cause defects.

[0003] To address the aforementioned issues, Chinese utility model patent CN214399175U discloses a fully active traction device. This device features a gear-driven housing with three pairs of rollers, a single-sided suspended roller design, and upper and lower rollers connected to a one-in-three-out gearbox via universal couplings. All rollers are actively driven, ensuring smooth transmission and better meeting production process requirements. The upper roller is pneumatically controlled by a cylinder to move up and down and connect with the lower roller. The pressure of the traction and upper roller cylinders is adjustable and maintained to ensure the clamping force of the steel bar and its smooth operation. This provides a guarantee for maintaining constant tension between the two traction machines under the control of the control system, thus solving the aforementioned problems.

[0004] However, the existing fully automatic traction equipment uses three pairs of rollers, which are used to process large-sized products and are not suitable for small-sized products. In addition, the drive mechanism in the existing equipment cannot better adjust the speed of the rollers and has low control precision. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a fully automatic roller traction machine with adjustable speed. A servo motor drives the transmission box, and a gear transmission structure within the transmission box controls the rotation of its two output shafts. These shafts are then connected to the upper and lower rollers in the traction mechanism via a cross-shaft universal coupling. This enables both rollers in the traction mechanism to be actively driven by servo motors, achieving high-precision motion control.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A fully automatic double-roller traction machine with adjustable speed is characterized by comprising a support frame, a servo motor, a reducer, a plum-shaped coupling, a key, a transmission box, and a cross-shaft universal coupling. The reducer is bolted to the support frame. One end of the reducer is connected to the output end of the servo motor, and the other end of the reducer is connected to the transmission box via the plum-shaped coupling and the key. The transmission box is connected to the traction mechanism via the cross-shaft universal coupling, and the traction mechanism is mounted on the support frame.

[0008] The bracket is equipped with a protective cover, and the cross-shaft universal coupling is located inside the protective cover. The protective cover protects the internal mechanical components and prevents external objects from entering.

[0009] Furthermore, the traction mechanism includes a cylinder, an upper roller, and a lower roller. The cylinder is connected to the upper roller to control the up and down movement of the upper roller to complete the docking with the lower roller. The upper roller and the lower roller are respectively connected to the transmission box through a cross-type universal coupling.

[0010] Furthermore, the transmission box is a gear transmission box with a one-input, two-output design. The input shaft of the gear transmission box is connected to the reducer, and the two output shafts are connected to the upper roller and the lower roller respectively through a cross-type universal coupling.

[0011] Preferably, the bracket is equipped with a manual valve, which enables the device to be manually controlled.

[0012] Preferably, a dual-unit is installed on one side of the bracket, through which connection with other control components is achieved.

[0013] Preferably, the bottom of the bracket is provided with multiple sets of floor mats, which are connected to the ground by anchor bolts.

[0014] The beneficial effects of this utility model are:

[0015] This utility model uses a servo motor to drive the transmission box, and controls the rotation of the two output shafts of the transmission box through the gear transmission structure inside the transmission box. It is then connected to the upper and lower rollers in the traction mechanism through a cross-shaft universal coupling, so that both rollers in the traction mechanism are active. The servo motor is used to drive the rollers, achieving high-precision motion control. The servo system has a high response speed to meet the needs of better speed adjustment.

[0016] This utility model uses a plum blossom coupling to connect the input shaft of the reducer and the transmission box. Because the plum blossom coupling itself has the functions of shock absorption, wear resistance and buffering, this utility model is more suitable for conveying occasions that require frequent forward and reverse starts, and can carry out processing operations with constant load.

They are then connected to the upper roller 22 and the lower roller 23 in the traction mechanism via the cross-type universal coupling 4, so that both rollers in the traction mechanism are active and driven by a servo motor 9, achieving high-precision motion control. The servo system has a high response speed to meet the needs of better speed adjustment.
