Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a loom that can automatically adjust tension. Background Technology

[0002] In the textile industry, fabric quality largely depends on yarn tension control and winding efficiency. Traditional loom winding devices struggle to precisely control yarn tension, leading to uneven tension and problems such as inconsistent fabric density and unclear weave. Moreover, during the winding process, structural defects in the equipment often result in uneven winding, yarn jamming, or even fabric detachment, affecting production efficiency and product quality. Utility Model Content

[0003] The main objective of this invention is to provide a loom device that can automatically adjust tension, 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 loom with automatic tension adjustment includes a base plate, with support feet fixedly connected to the four corners of the lower end of the base plate, a fixed plate fixedly connected to the upper right side of the base plate, an operation panel provided on the lower front side of the fixed plate, side plates fixedly connected to the left and upper ends of the base plate, an adjustment device fixedly connected to the left end of the left side plate, and a winding device movably connected to the adjustment device.

[0006] The adjusting device includes a first rotary motor and two connecting frames. The front and rear inner walls of both connecting frames are movably connected to connecting rods via bearings. The upper front and rear ends of the two connecting rods are movably connected to movable plates via bearings. The output end of the first rotary motor is fixedly connected to a screw through the left side plate. A movable loop is threaded onto the outer surface of the screw. A connecting block is fixedly connected to the upper outer surface of the movable loop. A first rotating shaft is movably connected to the front end of the connecting block. A traction rod is fixedly connected to the outer surface of the first rotating shaft. The right end of the first rotary motor is fixedly connected to the left end of the left side plate. The lower ends of both connecting frames are fixedly connected to the upper end of the base plate.

[0007] Preferably, the right end of the screw is movably connected to the left end of the right side plate via a bearing.

[0008] By adopting the above technical solution, the right end of the screw is movably connected to the left end of the right side plate through a bearing, which can provide stable support for the screw and ensure that it will not have axial displacement when rotating, making the transmission of the adjustment device smoother and ensuring the accuracy of tension adjustment.

[0009] Preferably, each of the two connecting frames has a through hole at its left end, the screw is disposed in the through hole, and the inner diameter of the through hole is larger than the outer diameter of the screw.

[0010] By adopting the above technical solution, the through holes at the left ends of the two connecting frames have an inner diameter larger than the outer diameter of the screw, providing space for the screw to rotate, avoiding interference, and ensuring its stable installation. This allows the screw to smoothly drive the movable loop, assisting the adjustment device in accurately adjusting the yarn tension.

[0011] Preferably, the end of the traction rod away from the first rotating shaft is fixedly connected to a second rotating shaft, and the rear end of the second rotating shaft is movably connected to the front right side of the movable plate.

[0012] By adopting the above technical solution, the traction rod is movably connected to the right side of the front end of the movable plate via the second rotating shaft, which can accurately transmit the movement of the first rotating shaft and flexibly adjust the posture of the movable plate. The assist adjustment device changes the yarn tension as needed, improving the flexibility and accuracy of tension adjustment.

[0013] Preferably, the winding device includes a second rotary motor and a driven pulley. The output end of the second rotary motor is fixedly connected to a driving pulley. The driving pulley and the driven pulley are connected together by a movable belt. A connecting block is fixedly connected to the front end of the driven pulley. A winding roller is fixedly connected to the front end of the connecting block. A cover is snapped onto the front side of the outer surface of the winding roller. The front end of the second rotary motor is fixedly connected to the rear end of the fixed plate. The rear end of the driven pulley is movably connected to the upper front end of the movable plate through a bearing.

[0014] By adopting the above technical solution: all components of the winding device work together; the second rotary motor drives the passive pulley via belt drive, and the connecting block makes the winding roller rotate synchronously, efficiently winding the fabric. A cover prevents the fabric from falling off, and a movable plate supports and ensures smooth rotation, guaranteeing efficient and orderly winding.

[0015] Preferably, the output end of the second rotary motor passes through the rear end of the fixing plate and extends to the front end of the fixing plate.

[0016] By adopting the above technical solution, the output end of the second rotary motor is inserted into the fixing plate, so that the motor is closely connected to the drive pulley, the power transmission path is shortened, energy loss is reduced, the structural layout is simplified, and the stable and efficient operation of the winding device is ensured.

[0017] Preferably, the connecting block is fixed to the passive pulley and the winding roller by welding.

[0018] By adopting the above technical solution—welding and fixing the connecting block to the passive pulley and the take-up roller—a stable connection structure can be constructed, ensuring seamless power transmission. This ensures that the take-up roller rotates synchronously with the passive pulley, avoiding relative displacement and helping the take-up device to complete the fabric take-up operation efficiently and stably.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this utility model, by setting an adjustment device, the first rotary motor drives the screw to rotate, and through the linkage of components such as the movable loop, connecting block, and traction rod, the position of the movable plate is precisely adjusted, thereby accurately controlling the yarn tension and ensuring that the fabric density is uniform and the texture is clear.

[0021] 2. In this utility model, by setting up a winding device, the connecting round block is welded and fixed to the passive belt pulley and the winding roller, ensuring stable power transmission and avoiding uneven winding due to loose parts. The clip-on cover on the front side of the winding roller effectively prevents the fabric from falling off from the front end during winding, reducing the risk of thread jamming and significantly improving production efficiency and product quality.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figure 1-5 This utility model provides a technical solution:

[0032] A loom with automatic tension adjustment includes a base plate 1, with support feet 2 fixedly connected to the four corners of the lower end of the base plate 1, a fixing plate 3 fixedly connected to the upper right side of the base plate 1, an operation panel 4 provided on the lower front side of the fixing plate 3, side plates 5 fixedly connected to the left and upper ends of the base plate 1, an adjustment device 6 fixedly connected to the left end of the left side plate 5, and a winding device 7 movably connected to the adjustment device 6.

[0033] In this embodiment, the adjusting device 6 includes a first rotary motor 61 and a connecting frame 62. Two connecting frames 62 are provided. The front and rear inner walls of both connecting frames 62 are movably connected to connecting rods 63 via bearings. The upper front and rear ends of the two connecting rods 63 are movably connected to movable plates 64 via bearings. The output end of the first rotary motor 61 is fixedly connected to a screw 65 through the left side plate 5. A movable loop 66 is threaded onto the outer surface of the screw 65. A connecting block 67 is fixedly connected to the upper outer surface of the movable loop 66. The front end of the connecting block 67 is movably connected to the first rotary motor 61. A traction rod 69 is fixedly connected to the outer surface of the first rotating shaft 68. The right end of the first rotary motor 61 is fixedly connected to the left end of the left side plate 5. The lower ends of the two connecting frames 62 are fixedly connected to the upper end of the base plate 1. The right end of the screw 65 is movably connected to the left end of the right side plate 5 through a bearing. The left ends of the two connecting frames 62 are each provided with a through hole that passes through to the left and right. The screw 65 is set in the through hole, and the inner diameter of the through hole is larger than the outer diameter of the screw 65. The end of the traction rod 69 away from the first rotating shaft 68 is fixedly connected to the second rotating shaft, and the rear end of the second rotating shaft is movably connected to the right front end of the movable plate 64.

[0034] Through the above scheme: When the adjusting device 6 is working, the first rotary motor 61 starts, and its output end drives the screw 65 to rotate. The right end of the screw 65 is movably connected to the left end of the right side plate 5 through a bearing to ensure smooth rotation. The screw 65 is located in the through hole at the left end of the connecting frame 62, and the inner diameter of the through hole is larger than the outer diameter of the screw, so it does not hinder its rotation. The rotation of the screw 65 causes the threaded movable loop 66 to move axially, and the connecting block 67 on the upper side of the outer surface of the movable loop 66 moves accordingly. The first rotating shaft 68 at the front end of the connecting block 67 drives the traction rod 69 to move, and the second rotating shaft at the other end of the traction rod 69 is connected to the right side of the front end of the movable plate 64. Since the movable plate 64 is movably connected to the connecting frame 62 through the connecting rod 63, the traction rod 69 pulls the movable plate 64 to rotate around the connecting rod 63, thereby realizing the adjustment of yarn tension.

[0035] In this embodiment, the winding device 7 includes a second rotary motor 71 and a passive pulley 73. The output end of the second rotary motor 71 is fixedly connected to a drive pulley 72. The drive pulley 72 and the passive pulley 73 are connected to a movable belt 74 for transmission. A connecting block 75 is fixedly connected to the front end of the passive pulley 73. A winding roller 76 is fixedly connected to the front end of the connecting block 75. A cover 77 is snapped onto the front side of the outer surface of the winding roller 76. The front end of the second rotary motor 71 is fixedly connected to the rear end of the fixed plate 3. The rear end of the passive pulley 73 is movably connected to the upper front end of the movable plate 64 through a bearing. The output end of the second rotary motor 71 passes through the rear end of the fixed plate 3 and extends to the front end of the fixed plate 3. The connecting block 75 is fixed to the passive pulley 73 and the winding roller 76 by welding.

[0036] Through the above scheme: When the winding device 7 operates, the second rotary motor 71 starts, and its output end passes from the rear end of the fixed plate 3 to the front end, driving the drive pulley 72, which is fixedly connected to it, to rotate at high speed. The drive pulley 72 transmits power to the driven pulley 73 through the movable belt 74. The rear end of the driven pulley 73 is movably connected to the upper front end of the movable plate 64 through a bearing to ensure stable rotation. Since the connecting block 75 is welded and fixed to the driven pulley 73 and the winding roller 76, when the driven pulley 73 rotates, the connecting block 75 drives the winding roller 76 to rotate synchronously, starting to wind up the fabric. The clip 77 that is snapped onto the front side of the outer surface of the winding roller 76 can effectively prevent the fabric from falling off from the front end during the winding process, ensuring the smooth progress of the winding work and completing the winding operation of the woven fabric.

[0037] It should be noted that this utility model is a loom device with automatic tension adjustment. During use, firstly, the power is turned on, the operation panel 4 is opened, and the loom device enters the working preparation state. The adjustment device 6 is activated, the first rotary motor 61 is started, and its output end drives the screw 65 to rotate. The screw 65 rotates smoothly under the support of the bearing at the left end of the right side plate 5. Since the outer surface of the screw 65 is threadedly connected to the movable loop 66, the rotation of the screw 65 causes the movable loop 66 to move along the axial direction of the screw 65. The connecting block 67 on the upper side of the movable loop 66 moves with it. The first rotating shaft 68 at the front end of the connecting block 67 drives the traction rod 69 to move. The second rotating shaft at the other end of the traction rod 69 is movably connected to the right side of the front end of the movable plate 64, thereby pulling the movable plate 64 to rotate around the connecting rod 63, realizing the initial adjustment of the yarn tension. The second rotary motor 71 is started, and the active belt pulley 72 fixed at its output end rotates, driving the passive belt pulley 73 to rotate through the movable belt 74. The rear end of the passive pulley 73 is movably connected to the upper front end of the movable plate 64 via a bearing to ensure its stable rotation. The connecting block 75, which is fixedly connected to the front end of the passive pulley 73, rotates synchronously, and the take-up roller 76 welded to the front end of the connecting block 75 begins to wind up the fabric. The cover 77, which is snapped onto the front of the outer surface of the take-up roller 76, prevents the fabric from falling off during the winding process.

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.
