Description

Technical Field

[0001] This utility model relates to the field of weaving machine technology, and in particular to a warp tension balancing device for weaving machines. Background Technology

[0002] The loom, also known as a spinning machine, weaving machine, or cotton spinning machine, was originally a human-powered loom. Research on shuttleless loom technology began in the 19th century, and it was gradually introduced to the international market from the 1950s onwards. Since the 1970s, many new types of shuttleless looms have been introduced to the market. Shuttleless looms have achieved significant results in improving fabric quality and increasing loom efficiency, and have been widely adopted in countries around the world, accelerating the process of upgrading weaving equipment.

[0003] Existing looms form fabrics through the interlacing of warp and weft yarns. When the loom starts, the yarn is drawn from the yarn tube and passes through various parts of the loom, such as the yarn feeding, heddle threading, and the movement of the upper and lower shuttles, ultimately forming interlaced fabric. During operation, the tension of the warp yarns is controlled by the back-and-forth movement of support rods installed on both sides of the loom using fasteners. However, in the operation of existing looms, the tension control device at the front end cannot guarantee the tension of the warp yarns at the back end, causing the warp yarns at the back end to slack during operation. This results in wrinkles in the warp yarns transmitted to the front end, affecting the efficiency of the interlacing process.

[0004] To address this issue, we propose a warp tension balancing device for looms. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a warp tension balancing device for a loom.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A lifting device is fixedly installed on both sides of the interior of the weaving machine body. A first fixed disc is installed at both the upper and lower ends of the lifting device. The first fixed disc is sleeved on both ends of a ball screw. A sliding block is installed on the surface of the ball screw. A support block is fixedly installed on the surface of the sliding block. Two sets of grooves are formed on the surface of the support block, and a fixing sleeve is installed inside the groove. A first fixing block is fixedly connected inside the fixing sleeve by mounting nails. A rotating block is installed on one side of the first fixing block. The rotating block is inserted into the end of a support spring. A limit block is installed at the front end of the support spring, and the support spring abuts against the rear end of the support top plate. A second fixing block is fixedly installed at the bottom of the fixing sleeve. A buffer spring is connected to the bottom of the second fixing block through a second fixed disc. The buffer spring abuts against the bottom of the support resistance block.

[0007] Preferably, a cover plate is fixedly installed on the surface of the lifting device, and the surface of the cover plate is provided with a through groove that is compatible with the sliding block.

[0008] Preferably, the surface of the sliding block is provided with a screw hole adapted to the ball screw, and the diameter of the first fixed disk is larger than the diameter of the surface of the sliding block.

[0009] Preferably, the end of the support spring has a hole that matches the rotating block, and is connected by a bearing.

[0010] Preferably, a limit block is inserted into the front end of the support spring, and a support top plate is installed at the top end of the support spring, and the support top plate is semi-circular.

[0011] Preferably, the buffer spring abuts against the end of the support resistance block, and the surface of the support resistance block has holes that are compatible with the support spring.

[0013] 1. This device features two sets of fixing sleeves mounted on the surface of a support block, with first fixing blocks installed on both sides inside the fixing sleeves and secured by mounting nails to prevent shaking or loosening during operation. Simultaneously, a rotating block is installed on one side of the first fixing block and inserted into the end of a support spring. A limit block is installed at the front end of the support spring, abutting against the end of the support top plate to prevent the warp yarns at the rear of the loom from loosening during transmission. This effective contact enhances the tension of the warp yarns, prevents slackness, avoids wrinkling of the warp yarns transmitted to the front end, and improves the efficiency of the weaving process.

[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] Reference Figure 1-4 A warp tension balancing device for a weaving machine includes: a weaving machine body 1, with lifting devices 2 fixedly installed on both sides inside the weaving machine body 1. First fixed discs 21 are installed at the upper and lower ends inside the lifting devices 2. The first fixed discs 21 are sleeved on both ends of a ball screw 22. Sliding blocks 24 are installed on the surface of the ball screw 22. Support blocks 25 are fixedly installed on the surface of the sliding blocks 24. Two sets of grooves are formed on the surface of the support blocks 25, and fixed sleeves 3 are installed inside the grooves. A first fixed block 31 is fixedly connected inside the fixed sleeve 3 via mounting nails 32. A rotating block 33 is installed on one side of the first fixed block 31. The rotating block 33 is inserted into the end of a support spring 34. A limit block 35 is installed at the front end of the support spring 34, and the support spring 34 abuts against the rear end of a support top plate 36. A second fixed block 4 is fixedly installed at the bottom of the fixed sleeve 3. A buffer spring 42 is connected to the bottom of the second fixed block 4 via a second fixed disc 41, and the buffer spring 42 abuts against the bottom of a support resistance block 43.

[0022] Furthermore, refer to Figure 1 and Figure 2 It can be seen that a cover plate is fixedly installed on the surface of the lifting device 2 to prevent impurities from entering the interior and affecting the movement of the sliding block 24. The surface of the cover plate is provided with a through groove that matches the sliding block 24 to avoid jamming during movement. The surface of the sliding block 24 is provided with a screw hole that matches the ball screw 22. The diameter of the first fixed disc 21 is larger than the diameter of the surface of the sliding block 24 to prevent the sliding block 24 from falling off during up and down movement.

[0023] Furthermore, refer to Figure 2and Figure 3 It can be seen that the end of the support spring 34 has a hole that matches the rotating block 33, which facilitates adjustment according to the warp yarn condition and prevents the warp yarn from breaking due to excessive tension. Through the bearing connection, the front end of the support spring 34 is inserted with a limit block 35 to facilitate limiting and prevent it from moving to a certain extent and continuing to adjust. The top of the support spring 34 is equipped with a support plate 36, which is convenient to abut against one side of the warp yarn to increase the tension of the warp yarn. The support plate 36 is semi-circular, which is convenient to abut against and prevents sharp corners from wearing down the warp yarn.

[0024] Furthermore, refer to Figure 4 It can be seen that the buffer spring 42 abuts against the end of the support resistance block 43, which helps to prevent the support spring 34 from swinging back and forth frequently during the rebound process, and the surface of the support resistance block 43 is provided with holes that are compatible with the support spring 34.

[0025] Working principle: In use, this invention starts the weaving machine 1, causing the warp yarns to rotate. When the tension of the warp yarns at the rear end relaxes, the drive motor 23 is started, driving the bearing inside the first fixed disc 21 to rotate the ball screw 22. At the same time, the support block 25 connected to the sliding block 24 moves up and down. When it moves to a suitable height, the support spring 34 inside the fixed sleeve 3, through the first fixed block 31 fixed by the mounting nail 32, drives the rotating block 33 to rotate, so that the support spring 34 abuts against the support top plate. When the warp tension is sufficient, the support spring 34 is fixed and limited by the limiting block 35. At this time, when the warp tension is sufficient, the support spring 34 is rotated and pulled back by the rotating block 33. Then, the second fixing block 4 installed inside the fixing sleeve 3 supports the buffer spring 42 to abut against the end of the support resistance block 43 by the second fixing disc 41 installed inside the second fixing block 4. The support resistance block 43 is fixed to the tail of the support spring 34 to buffer and prevent the support spring 34 from swinging back and forth.

[0026] The above is the complete working principle of this utility model.
