DETAILED DESCRIPTION

[0020] The following is a detailed description of an on-board electric heating cloth cutting device and a loom of the present invention with reference to the accompanying drawings.

[0021] See also Figure 1 、 Figure 2The present invention provides a technical solution: an on-board electric heating cloth cutting device, comprising a support rod 1, a swing arm 2, a mounting plate 3, a bearing assembly, a drive mechanism, a synchronous shaft 12, a cloth pressing rod 14, a mounting arm 13, and an electric heating wire assembly. The synchronous shaft 12 is provided with a drive mechanism, a swing arm 12, and a mounting arm 13 at each end. The support rod 1 is mounted on the inner side of a wall panel 21. A composite sleeve is installed in a hole in the swing arm 2. One end of the swing arm 2 is mounted on the end diameter of the support rod 1. The other end of the swing arm 2 is connected to the end of the cloth pressing rod 14 and is fixed in place by screws. One end of the mounting plate 3 is connected to the swing arm 2, and the other end of the mounting plate 3 is connected to the shaft end of the synchronous shaft 12. The drive mechanism is disposed on the outer side of the mounting plate 3 and drives the synchronous shaft 12 to rotate. The upper ends of the two mounting arms 13 are respectively connected to the respective ends of the synchronous shaft 12. The upper ends of the mounting arms 13 are sleeved on the synchronous shaft and fixedly connected by fasteners. The electric heating wire assembly is provided between the lower ends of the two mounting arms.

[0022] The driving mechanism includes a large synchronous pulley 7, a transfer rod 8, a motor mounting plate 9, a motor 10, a synchronous belt 11 and a small synchronous pulley 19. The motor mounting plate 9 is connected to the swing arm 2 through the transfer rod 8, the motor 10 is connected to the motor mounting plate 9, the small synchronous pulley 19 is connected to the output shaft of the motor 10, the large synchronous pulley 7 is positioned and mounted on the shaft end of the synchronous shaft 00 through the spacer 6, and the small synchronous pulley 19 and the large synchronous pulley 7 are driven by the synchronous belt 11. When the motor 10 is working, the small synchronous pulley 19 rotates. The rotation of the small synchronous pulley 19 is transmitted to the large synchronous pulley 19 through the synchronous belt 11. The rotation of the large synchronous pulley drives the synchronous shaft 12 to rotate. Since the mounting arm 13 is fixedly connected to the synchronous shaft 12, the rotation of the mounting arm 13 is realized.

[0023] Any structure that can drive the synchronous shaft to rotate is a variation of the drive mechanism, such as through various power forms such as chains, gears, cylinders, electric cylinders, etc., and is not limited to the specific structure of the drive mechanism disclosed in this utility model.

[0024] The two ends of the synchronous shaft 12 are connected to the corresponding mounting plates through bearing assemblies. The bearing assembly includes a bearing seat 4 and a bearing 5. The bearing seat 4 is connected to the mounting plate 3 through screws, and the bearing 5 is placed in the bearing seat 4.

[0025] like Figure 2As shown, the heating wire assembly includes an insulating base 15, a spring 16, an insulating cap 17, a terminal 18, and a heating wire 20. The two ends of the heating wire 20 pass through the corresponding through-holes at the end of the mounting arm 13 and are connected to the terminal 18. The insulating base 15 is located on one side of the mounting arm 13, the insulating cap 17 is located inside the terminal 18, and the spring 16 is located between the insulating cap 17 and the insulating base 15. A series spring is connected at one or both ends of the heating wire to provide flexible tension to compensate for the length change of the heating wire due to thermal expansion and contraction.

[0026] During normal operation, the cloth pressing rod 14 drives the entire mechanism to swing upward as the cloth roll diameter continues to increase. When the cloth roll diameter reaches the cloth drop requirement, the power of the motor 10 is transmitted to the synchronous shaft 12 through the small synchronous pulley 19, the synchronous belt 11, and the synchronous pulley 7, thereby driving the mounting arm 13 to drive the heating wire 20 to swing downward, achieving Figure 1 When the cloth cutting position is shown, the heated electric heating wire 20 cuts the cloth and completes the separation of the cloth roll. After the cloth is cut, the power moves in the opposite direction again, so that the cloth cutting mechanism is lifted back to the initial position and waits for the next action.

[0027] The utility model also provides a loom, which includes the above-mentioned on-board electric heating cloth cutting device. The loom can cut the cloth surface by utilizing the heat energy heated by the electric heating wire, thereby realizing automation, reducing labor intensity and improving work efficiency.

[0028] The above description is merely an illustration of some principles of the present invention. This specification is not intended to limit the present invention to the specific structure and applicable scope shown and described. Therefore, all corresponding modifications and equivalents that may be used fall within the scope of the patent applied for by the present invention.

[0029] Except for the technical features described in the specification, the remaining technical features are known to those skilled in the art.
