Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a direct-drive motor for looms that can be braked in an emergency. Background Technology

[0002] Rollers are key components in textile machinery, primarily used for fiber feeding, drafting, and output processes. Currently, rollers in textile machinery are mainly driven by electric motors. The drive method typically involves the motor rotating the loom rollers via belts, chains, gears, or other structures. However, these transmission methods are relatively complex, resulting in unstable transmission and a high failure rate, occasionally leading to fiber breakage or tangled fibers. Furthermore, existing drive structures lack emergency braking capabilities. When the aforementioned faults occur, the motor cannot stop immediately. Even after power is disconnected, the motor will continue to run for a period due to inertia, potentially causing secondary faults or damage, further increasing losses. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a direct-drive motor for looms with emergency braking capability, including a housing, a stator, a rotor, a main shaft, a sleeve, a rear end cover, and a braking mechanism.

[0004] Furthermore, the braking mechanism includes a flange, an electromagnet, an armature, and a positioning plate. The flange and the sleeve are fixedly connected by bolts. The electromagnet is mounted on the flange. The positioning plate is fixedly sleeved on the outside of the main shaft. The armature is positioned between the electromagnet and the positioning plate. The armature and the positioning plate are movably connected by multiple guide posts.

[0005] Furthermore, a first friction block is provided on the outer side of the electromagnet, and a second friction block is provided on the outer side of the armature, with the first friction block and the second friction block being arranged opposite to each other.

[0006] Furthermore, the positioning disk is provided with a guide groove, one end of the guide post is fixedly connected to the armature, and the other end is movably disposed in the guide groove.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-2 As shown, the direct-drive motor for looms with emergency braking in this embodiment includes a housing 1, a stator 2, a rotor 3, a main shaft 4, a sleeve 5, a rear end cover 6, and a braking mechanism 7. The stator 2 is fixedly installed on the inner wall of the housing 1. One end of the main shaft 4 is rotatably installed inside the housing 1 along the axial direction, and the other end extends outward. The rotor 3 is sleeved on the outside of the main shaft 4 and located inside the housing 1. The rotor 3 and the stator 2 are rotatably engaged. The sleeve 5 is sleeved on the outside of the main shaft 4, and one end is fixedly connected to the front end of the housing 1, and the other end is rotatably connected to the main shaft 4. The rear end cover 6 is fixedly installed at the rear end of the housing 1. The braking mechanism 7 is located between the sleeve 5 and the main shaft 4 and near the front end of the sleeve 5.

[0025] The front end of the sleeve 5 is rotatably connected to the main shaft 4 via the first bearing 8, the main shaft 4 is rotatably connected to the rear end cover 6 via the second bearing 9, and the rear end of the sleeve 5 is connected to the rear end cover 6 via multiple tie rod bolts 10.

[0026] The main shaft 4 has a tapered shaft 41 at its front end, and the front end of the tapered shaft 41 has a mounting hole 42 inside to facilitate connection with the roller.

[0027] like Figure 3 As shown, the braking mechanism 7 includes a flange 71, an electromagnet 72, an armature 73, and a positioning plate 74. The flange 71 is fixedly connected to the sleeve 5 by bolts. The electromagnet 72 is mounted on the flange 71. The positioning plate 74 is fixedly mounted on the outside of the main shaft 4. The armature 73 is located between the electromagnet 72 and the positioning plate 74, and the armature 73 and the positioning plate 74 are movably connected by multiple guide posts 75.

[0028] The electromagnet 72 is provided with a first friction block 76 on its outer side and the armature 73 is provided with a second friction block 77 on its outer side. The first friction block 76 and the second friction block 77 are arranged opposite to each other. The first friction block 76 and the second friction block 77 can be made of rubber material, so that the two can generate friction without affecting the electromagnet 72's attraction of the armature 73.

[0029] The positioning plate 75 is provided with a guide groove 78. One end of the guide post 75 is fixedly connected to the armature 73, and the other end is movably set in the guide groove 78. A tension spring 79 is also sleeved on the outside of the guide post 75. The two ends of the tension spring 79 are respectively connected to the armature 73 and the positioning plate 74.

[0030] The sleeve 5 is also provided with a front cover 11, which is sleeved on the outside of the main shaft 4 and a rotary sealing ring 12 is provided between the two.

[0031] like Figure 4 As shown, when this utility model is used, the roller 13 is sleeved on the outside of the sleeve 5, the inside of the roller 13 is connected to the tapered shaft 41 through the connecting seat 14, and the end is threadedly connected to the mounting hole 42 through bolts, thereby realizing the connection between the roller 13 and the main shaft 4.

[0032] When the loom is working, the motor drives the roller 13 to rotate. If the loom malfunctions, the system first cuts off the power to the motor and simultaneously energizes the electromagnet 72. After being energized, the electromagnet 72 attracts the armature 73, and the magnetic attraction is greater than the tension of the tension spring 79, causing the armature 73 to approach the electromagnet 72. This causes the first friction block 76 and the second friction block 77 to rub against each other, so that the main shaft 4 can stop rotating quickly, preventing the motor from continuing to run due to inertia and causing secondary malfunctions or damage, thereby avoiding further losses.

[0033] After the loom returns to normal, the system de-energizes the electromagnet 72. Under the action of the tension spring 79, the armature 73 separates from the electromagnet 72, and the motor can then drive the main shaft 4 to operate normally.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
