Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, specifically a cam shedding device for a high-speed water jet loom. Background Technology

[0002] The loom cam shedding mechanism drives the heald frame movement via a cam, achieving warp yarn layering to form the shed. It is a core component for weaving simple fabrics such as plain and twill weaves. Its structure is divided into two types: active and passive. The active type uses conjugate cams or grooved cams to synchronously control the heald frame's lifting and lowering, resulting in stable movement and adaptability to high speeds. The passive type relies on a cam to drive a single-stroke movement, with the return stroke completed by a return spring. This type is lower in cost but is prone to parameter changes due to spring fatigue over long-term use.

[0003] Utility model patent CN219470333U discloses a cam shedding device for a high-speed water jet loom, relating to the field of water jet loom technology. It includes a bracket, a drive rod, a horizontal moving rod, a drive mechanism, and a housing. The housing is located at the top of the bracket, and the drive rod is slidably connected inside the housing. A connecting frame is fixedly connected to one side of the drive rod, and a locking mechanism is provided inside the connecting frame. This cam shedding device for a high-speed water jet loom, through its locking mechanism, connecting plate, and connecting frame, allows for easy maintenance and replacement of the entire device. By pulling the pull ring outwards, the baffle is moved away from the connecting plate, and the connecting plate is then pulled outwards to detach it from the connecting frame. This facilitates the separation of the horizontal moving rod from the drive rod, enabling convenient maintenance and replacement of the entire cam shedding device. The disassembly process is simple, quick, and saves time and effort.

[0004] However, in common cam shedding devices, the contact stress between the cam and the follower is high and the friction is intense during use, which makes the cam and related transmission components prone to wear. If the worn parts are not replaced in time, the performance of the shedding device will be affected. Therefore, a cam shedding device for a high-speed water jet loom is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cam shedding device for a high-speed water jet loom, which has the advantages of real-time monitoring of the displacement of the driven support arm and timely detection of component wear, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cam shedding device for a high-speed water jet loom includes a mounting housing, a rotating shaft rotatably mounted on the inner sidewall of the mounting housing via a bearing, a driven arm fixedly mounted on the surface of the rotating shaft, a detection through hole on one side of the driven arm, and a wear detection component disposed inside the mounting housing.

[0008] The wear detection assembly includes two laser emitters fixedly installed on the inner wall of the mounting housing. The two laser emitters are respectively aligned with the detection through holes when the driven arm is displaced to its two endpoints. A laser receiver is fixedly installed on the inner wall of the mounting housing, and the laser receiver is located on the inner wall of the mounting housing away from the laser emitters.

[0009] Furthermore, a maintenance display screen is fixedly installed on one side of the mounting housing, and the maintenance display screen is electrically connected to the laser receiver.

[0010] Furthermore, the top of the mounting housing is provided with a through hole, which is adapted to the driven arm, and a connecting rod is rotatably mounted on the top of the driven arm.

[0011] Furthermore, a camshaft is rotatably mounted on the inner wall of the mounting housing via a bearing, a double-headed cam is fixedly mounted on the surface of the camshaft, and clamps are fixedly mounted on both sides of the double-headed cam. The double-headed cam is adapted to the driven support arm.

[0012] Furthermore, a drive motor is fixedly installed on one side of the mounting housing, and the output shaft of the drive motor is fixedly connected to one end of the camshaft.

[0013] Furthermore, a connecting base plate is fixedly installed at the bottom of the mounting housing, and a plurality of buffer pads are fixedly installed at the bottom of the connecting base plate, with the mounting base plate fixedly installed at the bottom of the buffer pads.

[0014] Furthermore, the mounting base plate is fixedly connected to the frame of the loom, and a sound-insulating lining is fixedly installed on the inner wall of the mounting shell.

[0015] Compared with the prior art, the present invention provides a cam shearing device for a high-speed water jet loom, which has the following advantages:

[0016] This high-speed water jet loom cam shedding device features a detection through-hole on one side of the driven arm. A laser emitter is fixedly installed on the inner wall of the mounting housing. When the driven arm rotates to its end point, the laser emitter aligns with the detection through-hole, allowing light to pass through and fall onto the laser receiver. When the driven arm or double-headed cam is worn, the driven arm cannot rotate to the preset end point, and the laser receiver cannot receive the laser light. This method detects wear on the driven arm or double-headed cam, solving the problem of common cam shedding devices where high contact stress and intense friction between the cam and the driven component lead to easy wear of the cam and related transmission components. If these worn components are not replaced in time, the performance of the shedding device will be affected. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 The high-speed water jet loom cam shedding device in this embodiment includes a mounting housing 1. A rotating shaft 2 is rotatably mounted on the inner side wall of the mounting housing 1 via a bearing. A driven support arm 3 is fixedly mounted on the surface of the rotating shaft 2. A detection through hole 4 is opened on one side of the driven support arm 3. A wear detection component is provided inside the mounting housing 1.

[0024] The wear detection component includes two laser emitters 5 fixedly installed on the inner wall of the mounting housing 1. The two laser emitters 5 are respectively aligned with the detection through holes 4 when the driven arm 3 is displaced to the two end points. A laser receiver 6 is fixedly installed on the inner wall of the mounting housing 1. The laser receiver 6 is located on the inner wall of the mounting housing 1 away from the laser emitters 5.

[0025] Secondly, a maintenance display screen 7 is fixedly installed on one side of the housing 1, and the maintenance display screen 7 is electrically connected to the laser receiver 6.

[0026] Specifically, when the internal components of the cam opening device are worn, the travel of the driven arm 3 is reduced, causing the laser emitted by the laser emitter 5 to be unable to reach the laser receiver 6 through the detection through hole 4. Since the laser receiver 6 cannot receive the laser, it is determined that the internal components of the cam opening device are worn, which is displayed on the maintenance display screen 7, prompting the staff to pay attention to timely maintenance and replacement.

[0027] Please see Figure 1 and Figure 2 In this embodiment, the top of the housing 1 is provided with a through hole 8, which is adapted to the driven arm 3. A connecting rod 9 is rotatably installed on the top of the driven arm 3.

[0028] Please see Figure 1 and Figure 3 In this embodiment, a camshaft 10 is rotatably mounted on the inner wall of the housing 1 via a bearing. A double-headed cam 11 is fixedly mounted on the surface of the camshaft 10. Clamping plates 12 are fixedly mounted on both sides of the double-headed cam 11. The double-headed cam 11 is adapted to the driven support arm 3.

[0029] A drive motor 13 is fixedly mounted on one side of the housing 1, and the output shaft of the drive motor 13 is fixedly connected to one end of the camshaft 10. The drive motor 13 drives the camshaft 10 to rotate, which in turn drives the double-headed cam 11 to rotate, thereby moving the driven support arm 3.

[0030] Please see Figure 1 In this embodiment, a connecting base plate 14 is fixedly installed on the bottom of the mounting shell 1, a plurality of buffer pads 15 are fixedly installed on the bottom of the connecting base plate 14, and a mounting base plate 16 is fixedly installed on the bottom of the buffer pads 15.

[0031] The mounting base plate 16 is fixedly connected to the frame of the loom, and a sound-insulating liner 17 is fixedly installed on the inner wall of the mounting housing 1. The buffer pad 15 buffers and absorbs the vibration of the mounting housing 1, preventing the vibration from being transmitted to the frame of the loom and increasing the service life of the frame. The sound-insulating liner 17 absorbs the noise of the components and reduces the impact on the environment.

[0032] The working principle of the above embodiment is as follows: When the internal components of the cam opening device are worn, the stroke of the driven arm 3 is reduced, causing the laser emitted by the laser emitter 5 to be unable to reach the laser receiver 6 through the detection through hole 4. Since the laser receiver 6 cannot receive the laser, it is determined that the internal components of the cam opening device are worn, which is displayed on the maintenance display screen 7, prompting the staff to pay attention to timely maintenance and replacement.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
