Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, specifically to a fabric roll structure for a rapier loom. Background Technology

[0002] A rapier loom is a shuttleless loom that uses a rapier weft inserter to guide the weft yarn into the shed. It can adapt to a wider variety of fabrics, while also having a high weft insertion speed and low machine noise. It has significant advantages in the production of high-end and wide-width fabrics. During the operation of a rapier loom, the fabric roll is usually used as a winding device for the finished fabric. It can continuously roll the fabric into a roll with a certain shape through frictional torque for subsequent processing.

[0003] According to the Chinese Patent Publication No. CN217579248U, entitled "A Fabric Roller Structure for a Spindle Loom that is Easy to Adjust", the main features described are a fabric roll, a rotating rod fixedly installed on the inner wall of the fabric roll, a mounting base movably installed at one end of the rotating rod, a locking rod movably installed in the groove at the top of the rotating rod, a first rotating shaft fixedly installed on one side of the mounting base, one end of the first rotating shaft passing through to one side of the support base and extending into the interior of the support base, an electric push rod fixedly installed at the bottom of the support base, a nut seat fixedly installed at the bottom of the electric push rod, and the nut seat located inside the support base plate.

[0004] The aforementioned patent utilizes a nut seat and positive and negative lead screws. The rotating positive and negative lead screws, connected to the nut seat by threads, can move the mounting seats on both sides. The distance between the two mounting seats can be adjusted according to the length of different fabric rolls to accommodate different lengths of fabric rolls. Simultaneously, an electric push rod is provided, which can drive the fabric roll to move vertically, thereby facilitating the adjustment of the fabric roll's height. In conjunction with a locking rod, the fabric roll can be quickly installed and disassembled by engaging with the rotating rod. No tools are required during installation and disassembly, resulting in high efficiency.

[0005] The above-mentioned adjustment of the fabric roll roller is achieved by using a movable mounting base, a telescopic electric push rod, and a locking rod. However, the fabric roll roller needs to maintain uniform and stable fabric tension during actual operation. Since the diameter of the fabric roll roller gradually increases as the roll is rolled, if the rotation speed of the fabric roll roller cannot be reduced accordingly as the diameter of the roll increases, it will lead to inconsistent fabric tension, affecting fabric quality and causing problems such as wrinkles, looseness, or tightness in the fabric. Utility Model Content

[0006] In view of the deficiencies in the prior art, this utility model provides a fabric roll structure for a rapier loom to improve the tension stability of the fabric roll during rotation and reduce problems such as fabric wrinkles.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a fabric roll structure for a shuttle loom, including a fixed frame, an electric push rod fixedly connected to the upper center of the fixed frame by bolts, a support plate fixedly connected to the output end of the electric push rod, a first groove on the support plate, a first motor fixedly connected to one side of the support plate in the first groove, a bidirectional screw fixedly connected to the output end of the first motor, movable plates threadedly connected to both sides of the bidirectional screw, a second groove on the movable plate, a second motor fixedly connected to the upper side of the movable plate in the second groove, an adjusting screw fixedly connected to the output end of the second motor, the adjusting screw being located on an eccentric side within the second groove, a slider threadedly connected to the adjusting screw, a servo motor fixedly connected to one of the sliders, a rotating sleeve fixedly connected to the output end of the servo motor, the other slider rotatably connected to the rotating sleeve, the rotating sleeve engaging the fabric roll body, an auxiliary rod fixedly connected to the second groove, a pressure plate sleeved on the auxiliary rod, a stabilizing roller rotatably connected between the two pressure plates, and a compression spring sleeved on the upper side of the auxiliary rod above the stabilizing roller.

[0008] As a preferred technical solution of this utility model, the auxiliary rod is sleeved on the upper side of the pressure plate with an energy-releasing plate, and a gasket is fixedly connected to the bottom side of the energy-releasing plate by adhesive, and the gasket is in contact with the pressure plate.

[0009] As a preferred technical solution of this utility model, a limiting rod is provided on the upper side of the energy release plate, and the limiting rod is threadedly connected to the moving plate.

[0010] As a preferred technical solution of this utility model, a U-shaped sleeve is in contact with one side of the bottom end of the pressure plate, and when the U-shaped sleeve is located between the pressure plate and the slider, the stabilizing roller and the fabric rolling roller body do not contact each other.

[0011] As a preferred technical solution of this utility model, the upper end of the support plate is fixedly connected with vertical rods on all four sides, and the vertical rods are movably inserted into the fixing bracket.

[0012] This utility model has the following advantages: (1) By setting up a stabilizing roller and related structures such as compression springs and pressure plates, the stabilizing roller can always maintain a certain pressure contact with the fabric on the roll body under the action of the compression spring. As the diameter of the fabric roll on the roll body gradually increases, the stabilizing roller can adaptively adjust its position under pressure to ensure the stability of the fabric tension during the winding process, reduce problems such as wrinkles, looseness or tightness caused by inconsistent tension, and help improve the quality of the fabric.

[0013] (2) The height of the support plate can be adjusted by using an electric push rod, thereby adjusting the height of the fabric roll body; the first motor drives the bidirectional screw to rotate, which can make the moving plates on both sides move closer or further apart to adapt to fabric roll bodies of different lengths; the second motor drives the adjusting screw to rotate, which can move the slider, making it convenient to install and disassemble the fabric roll body, and also convenient to adjust the position of the fabric roll body according to the actual situation, with good flexibility and versatility.

[0014] (3) By setting the energy release plate and the limiting rod, the position of the energy release plate on the auxiliary rod can be adjusted, thereby changing the compression amount of the compression spring, and then adjusting the pressure of the stabilizing roller on the fabric. The tension control can be flexibly adjusted according to the characteristics and needs of different fabrics, further improving the applicability of the structure. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The illustrated fabric roll structure for a rapier loom includes a fixed frame 1. An electric push rod 2 is bolted to the center of the upper end of the fixed frame 1. The electric push rod 2 allows the support plate 3 to move up and down, facilitating the up and down movement of the fabric roll body 11 and adjusting its height. The output end of the electric push rod 2 is fixedly connected to the support plate 3. A first groove 4 is formed on the support plate 3. A first motor is fixedly connected to one side of the support plate 3 near the first groove 4. The first motor drives the rotation of a bidirectional screw 5, causing relative movement of two moving plates 6 and a rotating sleeve 10, thereby clamping fabric roll bodies 11 and stabilizing rollers 14 of different lengths. The connection structure between the stabilizing roller 14 and the pressure plate 13 can be configured to match the structure of the rotating sleeve 10. The output end of the first motor is fixedly connected to the bidirectional screw 5. Moving plates 6 are threaded to both sides of the bidirectional screw 5. A second groove 7 is formed on the moving plate 6. A second motor is fixedly connected to the moving plate 6 near the second groove 7. An adjusting screw 8 is fixedly connected to the output end. The start of the second motor can drive the adjusting screw 8 to rotate, which can make the slider 9 move up and down. The pressure plate 13 has a circular through hole. At the same time, the adjusting screw 8 does not contact the pressure plate 13. The adjusting screw 8 is located on the eccentric side in the second groove 7. The adjusting screw 8 is threadedly connected to the slider 9. One of the sliders 9 is fixedly connected to a servo motor. The output end of the servo motor is fixedly connected to a rotating sleeve 10. The servo motor drives the rotating sleeve 10 to rotate, and through the cross recess and cross protrusion structure, it makes the fabric roll body 11 rotate and roll up the fabric. The rotating sleeve 10 is provided with a cross recess, and both ends of the fabric roll body 11 are provided with cross protrusions. The other slider 9 is rotatably connected to the rotating sleeve 10. The rotating sleeve 10 is engaged with the fabric roll body 11. An auxiliary rod 12 is fixedly connected in the second groove 7. A pressure plate 13 is sleeved on the auxiliary rod 12. A stabilizing roller 14 is rotatably connected between the two pressure plates 13. A compression spring 15 is sleeved on the upper side of the stabilizing roller 14 on the auxiliary rod 12.

[0019] A support structure can be provided on the bottom side of the fabric roll body 11 to prevent increased wear caused by the increased weight of the electric push rod 2.

[0020] The output ends of both the screw structure and the electric push rod can be equipped with telescopic covers to prevent dust from sticking during the operation of the shuttle loom and reduce motion sluggishness.

[0021] Among them, the auxiliary rod 12 is sleeved on the upper side of the pressure plate 13 and the energy release plate 16 is fixedly connected to the bottom side of the energy release plate 16 by adhesive, and the gasket 17 is in contact with the pressure plate 13.

[0022] During the equipment installation preparation phase, when it is necessary to adjust the pressure of the stabilizing roller 14 on the fabric according to different fabric characteristics and requirements, the operator rotates the limiting rod 18 threadedly connected to the moving plate 6. Since the limiting rod 18 is provided on the upper side of the energy release plate 16 and the energy release plate 16 is sleeved on the auxiliary rod 12, the rotation of the limiting rod 18 will cause the energy release plate 16 to move up and down on the auxiliary rod 12. A gasket 17 is glued to the bottom side of the energy release plate 16, and the gasket 17 contacts the pressure plate 13. The movement of the energy release plate 16 will change its pressure on the pressure plate 13, thereby changing the compression of the compression spring 15.

[0023] Among them, a limit rod 18 is provided on the upper side of the energy release plate 16, and the limit rod 18 is threadedly connected to the moving plate 6.

[0024] The limiting rod 18 is threadedly connected to the movable plate 6. When the position of the energy release plate 16 needs to be adjusted, the operator rotates the limiting rod 18. The limiting rod 18 moves up and down under the action of the thread, thereby pushing or pulling the energy release plate 16 on the auxiliary rod 12 to achieve precise control of the position of the energy release plate 16.

[0025] Among them, a U-shaped sleeve 20 is in contact with one side of the bottom end of the pressure plate 13. When the U-shaped sleeve 20 is located between the pressure plate 13 and the slider 9, the stabilizing roller 14 and the fabric rolling roller body 11 are not in contact.

[0026] When installing or removing the fabric roll body 11, the operator places the U-shaped retainer 20 between the bottom side of the pressure plate 13 and the slider 9. Due to the obstruction of the U-shaped retainer 20, the pressure plate 13 cannot move downward under the action of the compression spring 15, thereby separating the stabilizing roller 14 from the fabric roll body 11. After the installation or removal operation of the fabric roll body 11 is completed, the U-shaped retainer 20 is removed, and the stabilizing roller 14 re-engages with the fabric on the fabric roll body 11 under the action of the compression spring 15.

[0027] Among them, vertical rods 19 are fixedly connected to the four sides of the upper end of the support plate 3, and the vertical rods 19 are movably inserted into the fixing frame 1.

[0028] During equipment operation, when the electric push rod 2 drives the support plate 3 to move up and down, or when the first motor drives the bidirectional screw 5 to rotate, causing the moving plates 6 to move closer or further apart, the vertical rods 19 fixedly connected to the four sides of the upper end of the moving plate 6 will be movably inserted into the fixed frame 1, and the vertical rods 19 will slide accordingly on the fixed frame 1 as the moving plate 6 moves.

[0029] Working principle: According to actual production needs, the electric push rod 2 at the upper end of the fixed frame 1 is activated. The output end of the electric push rod 2 drives the support plate 3 to move up and down, thereby adjusting the height of the entire fabric roll structure to a suitable position. The vertical rods 19 fixedly connected to the four sides of the upper end of the moving plate 6 are movably inserted into the fixed frame 1, which guides and stabilizes the movement of the moving plate 6. Then, the first motor on one side of the first groove 4 on the support plate 3 is activated. The output end of the first motor drives the bidirectional screw 5 to rotate. Since the moving plates 6 are threaded on both sides of the bidirectional screw 5, the moving plates 6 on both sides will move closer or further away from each other under the rotation of the bidirectional screw 5 to adapt to the different lengths of the fabric roll body 11. Then, the connection structure between the stabilizing roller 14 and the pressure plate 13 is set to the same structure as the rotating sleeve 10 (a cross recess is set at the rotating sleeve 10, and cross protrusions are set at both ends of the fabric roll body 11), ensuring that the stabilizing roller 14 can be stably installed. Meanwhile, an energy-releasing plate 16 is sleeved on the auxiliary rod 12. A gasket 17 is fixedly connected to the bottom side of the energy-releasing plate 16 by adhesive. The gasket 17 is in contact with the pressure plate 13. By rotating the limiting rod 18 connected to the moving plate 6 by the thread, the position of the energy-releasing plate 16 on the auxiliary rod 12 can be adjusted, thereby changing the compression amount of the compression spring 15 and adjusting the pressure of the stabilizing roller 14 on the fabric. At the same time, the second motor located on the second groove 7 of the moving plate 6 is started, and the output end of the second motor drives the adjusting screw 8 to rotate. Since the adjusting screw 8 is located on the eccentric side of the second groove 7 and is threadedly connected to the slider 9, the slider 9 can move up and down under the rotation of the adjusting screw 8. The slider 9 is adjusted to a suitable height, and then the two ends of the roll body 11 are respectively engaged with the rotating sleeves 10 on the two sliders 9 (using the cross recess of the rotating sleeve 10 and the cross protrusion at both ends of the roll body 11 to cooperate), thus completing the installation of the roll body 11. Then, the servo motor on one of the sliders 9 is started. The output end of the servo motor drives the rotating sleeve 10 to rotate. Through the cooperation of the cross recess and the cross protrusion, the roll body 11 is rotated, and the fabric is started to be wound up. During the winding process, as the diameter of the fabric roll on the roll body 11 gradually increases, under the action of the compression spring 15 sleeved on the auxiliary rod 12, the pressure plate 13 drives the stabilizing roller 14 to always maintain a certain pressure contact with the fabric on the roll body 11. The stabilizing roller 14 can adaptively adjust its position to ensure the stability of the tension of the fabric during the winding process. When it is necessary for the stabilizing roller 14 to not contact the fabric roll body 11 (e.g., when installing or removing the fabric roll body 11), place the U-shaped sleeve 20 between the bottom side of the pressure plate 13 and the slider 9 to separate the stabilizing roller 14 from the fabric roll body 11.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0031] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
