Description

Technical Field

[0001] This utility model relates to the field of water jet loom transmission technology, and in particular to a low-noise transmission structure for a water jet loom. Background Technology

[0002] A water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. Its core advantage lies in the high frictional traction force and low diffusion of the water flow on the weft yarn during the weft insertion process. It is especially suitable for weaving smooth synthetic fiber (such as polyester and nylon) and glass fiber filament fabrics. During operation, a pulley is installed at one end of the take-up roller of the water jet loom. The pulley on the motor and the belt work together to drive the pulley on the take-up roller to rotate, thus completing the transmission work. This allows the take-up roller to perform the take-up action. However, during the transmission process using a belt, the belt may become loose. When the belt becomes loose, it will generate noise during transmission. When the belt generates noise, it needs to be manually dealt with, which is quite troublesome. Utility Model Content

[0003] The main objective of this invention is to provide a low-noise transmission structure for a water jet loom, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A low-noise transmission structure for a water-jet loom includes a support frame and a take-up roller. The take-up roller is movably mounted on the lower end of the support frame. A first pulley is fixedly mounted on one end of the take-up roller. A drive motor is fixedly mounted on the upper surface of one side of the support frame, located at the front. A second pulley is fixedly mounted on the output end of the drive motor. A movable sleeve is mounted on the front surface of one side of the support frame, near the bottom. An extension rod is fixedly mounted on the front surface of the movable sleeve. A roller is movably fitted on the surface of the extension rod. Auxiliary rings are fitted on the surface of the extension rod, located at the front and rear ends of the roller. A fastening cap is threaded onto the front end of the extension rod.

[0006] More preferably, four locking blocks are fixedly installed on the surface of the extension rod near the front and rear ends. The four locking blocks are distributed in a matrix on the surface of the extension rod. The surface of the extension rod near the front end is provided with threads. The number of movable sleeves is two, and the two movable sleeves are distributed vertically.

[0007] In a further preferred embodiment, a lifting groove is provided on one side of the front surface of the support frame, a guide rod is fixedly installed inside the lifting groove, and a spring is sleeved on the surface of the guide rod.

[0008] More preferably, there are two lifting slots, which are distributed vertically. The rear end of the movable sleeve is fitted onto the guide rod. One end of the spring is fixed to the movable sleeve, and the other end of the spring is fixed to the ends of the two lifting slots that are far apart from each other.

[0009] More preferably, the inner surface of the auxiliary ring is provided with a groove that matches the locking block, and a ball bearing is movably embedded on the side of the auxiliary ring opposite to the roller. The number of the ball bearings is several, and the several ball bearings are distributed in a ring on the auxiliary ring.

[0010] More preferably, belts are fitted onto the first and second pulleys, with the roller on the upper movable sleeve in contact with the outer upper surface of the belt, and the roller on the lower movable sleeve in contact with the outer lower surface of the belt.

[0011] Compared with the prior art, this utility model proposes a low-noise transmission structure for a water jet loom, which has the following beneficial effects:

[0012] In this invention, by setting up a support frame, a movable sleeve, rollers, an auxiliary ring, and a fastening cap in cooperation, the movable sleeve, under the action of a spring, ensures that the roller on the upper movable sleeve is always in contact with the outer upper surface of the belt, and the roller on the lower movable sleeve is always in contact with the outer lower surface of the belt, and exerts an inward squeezing force on the belt. In this way, when the belt loosens, the two rollers are always in contact with the belt under the action of the spring, and exert an inward squeezing force on the belt, so that the belt can always be kept taut, and there will be no noise or need for manual adjustment due to belt loosening.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 1-4 As shown, a low-noise transmission structure for a water jet loom includes a support frame 1 and a take-up roller 4. The take-up roller 4 is movably installed at the lower end of the support frame 1. A first pulley 5 is fixedly installed at one end of the take-up roller 4. A drive motor 2 is fixedly installed on the upper surface of one side of the support frame 1, located at the front. A second pulley 3 is fixedly installed at the output end of the drive motor 2. A movable sleeve 6 is installed on the front surface of one side of the support frame 1, near the bottom. An extension rod 601 is fixedly installed on the front surface of the movable sleeve 6. A roller 7 is movably sleeved on the surface of the extension rod 601. An auxiliary ring 8 is sleeved on the surface of the extension rod 601, located at the front and rear ends of the roller 7. A fastening cap 9 is threaded onto the front end of the extension rod 601.

[0022] In a preferred embodiment: four locking blocks 602 are fixedly installed on the surface of the extension rod 601 near the front and rear ends. The four locking blocks 602 are distributed in a matrix on the surface of the extension rod 601. The surface of the extension rod 601 near the front end is provided with threads. There are two movable sleeves 6, which are distributed vertically.

[0023] In the above structure, when the locking block 602 is embedded in the locking groove 802, the installation angle of the auxiliary ring 8 is limited, so that the auxiliary ring 8 will not rotate. Since the fastening cap 9 is threaded on the extension rod 601, when the roller 7 needs to be removed, the fastening cap 9 is rotated to remove it from the end of the extension rod 601. Then, the auxiliary ring 8 at one end of the roller 7 can be removed, and the roller 7 can be removed from the extension rod 601.

[0024] In a preferred embodiment: a lifting groove 101 is provided on the front surface of one side of the support frame 1, a guide rod 102 is fixedly installed inside the lifting groove 101, and a spring 103 is sleeved on the surface of the guide rod 102.

[0025] In a preferred embodiment: there are two lifting slots 101, which are distributed vertically. The rear end of the movable sleeve 6 is sleeved on the guide rod 102. One end of the spring 103 is fixed to the movable sleeve 6, and the other end of the spring 103 is fixed to the ends of the two lifting slots 101 that are far apart from each other.

[0026] In the above structure, one end of the spring 103 is fixed to the movable sleeve 6, and the other end is fixed to one end of the lifting groove 101. In this state, the spring 103 exerts a pulling force on the movable sleeve 6. This pulling force allows the roller 7 on the movable sleeve 6 to contact the belt, and the pulling force of the two springs 103 causes the two movable sleeves 6 to tend to move closer to each other. Thus, when the belt becomes loose, the spring 103, under its elastic force, causes the two movable sleeves 6 to move closer to each other, thereby causing the roller 7 to exert a squeezing force on the belt. This can tighten the loose belt again and prevent the loose belt from making noise during operation.

[0027] In a preferred embodiment: the inner surface of the auxiliary ring 8 is provided with a slot 802 that is adapted to the locking block 602, and a ball bearing 801 is movably embedded on the side of the auxiliary ring 8 opposite to the roller 7. The number of balls bearing 801 is several, and the several balls bearing 801 are distributed in a ring on the auxiliary ring 8.

[0028] In the above structure, the balls 801 of the auxiliary ring 8 are in contact with the roller 7. In this way, when the belt runs and drives the roller 7 to rotate, the roller 7 will not contact the auxiliary ring 8 and generate friction noise. The roller 7 will only contact the balls 801. Since the balls 801 have rolling characteristics, the coefficient of friction between them is small, so that the roller 7 will not generate noise when it rolls. The roller 7 is equipped with a bearing, which avoids friction noise between the roller 7 and the extension rod 601.

[0029] In a preferred embodiment: belts are fitted on the first pulley 5 and the second pulley 3, the roller 7 on the upper movable sleeve 6 contacts the outer upper surface of the belt, and the roller 7 on the lower movable sleeve 6 contacts the outer lower surface of the belt.

[0030] In use, when the drive motor 2 starts, it drives the second pulley 3 to rotate. The second pulley 3, in turn, drives the first pulley 5 to rotate via the belt, thereby causing the take-up roller 4 to wind up. Under the action of the spring 103, the roller 7 on the upper movable sleeve 6 is always in contact with the outer upper surface of the belt, and the spring 103 has a downward pulling tendency on the movable sleeve 6. The roller 7 on the lower movable sleeve 6 is always in contact with the outer lower surface of the belt, and the spring 103 has an upward pulling tendency on the movable sleeve 6. In this way, when the belt becomes loose, the two rollers 7 are always in contact with the belt under the action of the spring 103, and exert a tendency to squeeze the belt inward. This keeps the belt taut and prevents noise and manual adjustment due to belt loosening.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
