Description

Technical Field

[0001] This utility model relates to the field of loom weaving technology, specifically to a support device and loom capable of compensating for the length of the fabric roll. Background Technology

[0002] As the fabric is wound up during the weaving process, the diameter of the fabric roll on the roll gradually increases, and the weight also increases. This causes the roll to deform to a certain extent, which leads to changes in the fit between the roll and the supports at both ends. These changes cannot be corrected during the weaving process and can cause axial displacement of the roll or even jumping.

[0003] Chinese patent provides an adjustable fabric roll holder, publication number CN203392561U, which includes a base bearing, a fixed seat, and a positioning locking rod. The fabric roll has extension shafts on both sides. The base bearing is fitted onto the extension shafts on both sides of the fabric roll. The extension end of the fixed seat is connected to the extension shaft of the fabric roll. The fixed seat is installed in the fabric rolling equipment by a fixing component. The extension end of the fixed seat has an adjustable positioning groove, and the adjustable positioning groove has a positioning locking rod.

[0004] The adjustable fabric roll holder mentioned above can only be adjusted by manually operating the positioning locking rod to adjust the length of the extended shaft. However, during the adjustment process, problems such as excessively large or small gaps may occur. In addition, the installation dimensions of the shaft head of the fabric roll are no longer standard after long-term use. Under such circumstances, the fabric roll may get stuck. Therefore, this patent still cannot meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a support device and a loom capable of compensating for the length of the fabric roll, which solves the problems in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a support device for compensating the length of a fabric roll, the structure of which includes a fixed seat, a spring and stroke adjustment mechanism and a positioning pin. The inner hole of the fixed seat is inserted into a support shaft. The inner hole of the support shaft is provided with a movable spindle and a spring. The spring and stroke adjustment mechanism is provided on one side of the inner hole of the fixed seat. A pulley is sleeved on the outside of the fixed seat. The pulley is connected to a power mechanism. The positioning pin is provided on the pulley.

[0007] Furthermore, the outer wall of the pulley is provided with a rack that cooperates with the power component. The pulley is installed in conjunction with the outer circle of the fixed seat. The outer circumferential wall of the pulley is provided with an arc-shaped guide groove. The fixed seat and the support shaft are respectively provided with transverse grooves. The positioning pin passes through the guide groove of the pulley, the transverse groove of the fixed seat, and the transverse groove of the support shaft in sequence and is threadedly connected to the movable spindle.

[0008] The technical effect of adopting the above-mentioned further solution is that the pulley rotates under the drive of the power mechanism, and the positioning pin can move along the guide groove. The guide groove is arc-shaped and plays the role of guiding the positioning pin. The movement of the positioning pin drives the movement of the movable spindle and the support shaft, thereby realizing the automation and accuracy of automatic fabric roll length compensation.

[0009] Furthermore, the elasticity and stroke adjustment mechanism includes an adjustment seat, a fastening nut, and an adjusting screw. The adjustment seat is threadedly connected to the end of the support shaft, the adjusting screw is threadedly connected to the adjustment seat, and one end of the adjusting screw passes through the threaded hole of the adjustment seat and abuts against the end of the movable spindle. The fastening nut is threadedly engaged with the adjusting screw.

[0010] The technical effect of adopting the above-mentioned further solution is that by rotating the adjusting screw to tighten the movable mandrel, the movable mandrel compresses the spring, thereby realizing the adjustment of the spring force and the movement stroke of the support shaft, so that the spring maintains a certain amount of compression, and the fabric roll roller continuously receives the pressure of the spring, thus maintaining the working position for a long time.

[0011] Furthermore, a bearing housing is provided on one side of the support shaft, and the bearing housing contains a bearing, a shaft retaining ring, and a hole retaining ring.

[0012] Furthermore, the power mechanism is a synchronous belt drive or a chain drive.

[0013] The technical effect of adopting the above-mentioned further solution is that by setting synchronous belt drive or chain drive, the support device of this utility model can cooperate with existing power components to realize the automation of cloth roll roller adjustment, thereby reducing costs by utilizing existing power.

[0014] Furthermore, one end of the spring is connected to the end of the movable spindle, and the other end of the spring is connected to the inner wall of the support shaft.

[0015] The technical effect of adopting the above-mentioned further solution is that, since the two ends of the spring are respectively connected to the corresponding shaft end and the inner hole wall, the reliability of the spring connection is ensured, and the spring can continuously maintain pressure.

[0016] Furthermore, a pulley positioning plate is provided on one side of the pulley.

[0017] The technical effect of adopting the above-mentioned further solution is that by setting a pulley positioning plate at the outer end of the pulley, it can be used for axial positioning of the pulley and prevent the pulley from moving outward when rotating.

[0018] Furthermore, the side wall of the pulley positioning plate is provided with a threaded hole, and an oil cup for lubricating the support device is provided in the threaded hole.

[0019] The technical effect of adopting the above-mentioned further solution is that by injecting oil into the support device through the oil cup, the lubrication of the support device can be ensured, thereby making the movement of each component smooth, reducing wear, and extending the service life of the device.

[0020] A loom includes a support device capable of compensating for the length of the fabric roll.

[0021] The beneficial effects of this utility model are:

[0022] 1. The support device of this utility model is fitted with a pulley and a fixed seat. The side wall of the pulley is provided with an irregular guide groove, and a positioning pin is installed in the guide groove. Since the positioning pin is threadedly fixed to the movable mandrel, when the pulley rotates under the drive of the power mechanism, the positioning pin moves along the guide groove. At the same time, the positioning pin drives the movable mandrel and the support shaft to move linearly, so that the bearing at the end of the support shaft is inserted into the fabric roll roller, thereby realizing the automatic adjustment of the fabric roll roller length compensation. The adjustment accuracy is high, time and labor are saved, and work efficiency is improved.

[0023] 2. Because an adjusting screw is provided on one side of the fixed seat, the pressure of the movable mandrel top spring can be adjusted by rotating the adjusting screw, so that the spring always maintains a certain compression force, improving the stability of the connection between the support shaft and the fabric roll roller. When the fabric roll roller continuously receives the pressure of the spring, it can maintain the working position for a long time. Attached Figure Description

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.

[0032] This utility model provides a support device for compensating the length of a fabric roll, which is installed on both sides of the fabric roll. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the right-side support device is described in detail as an example. This support device includes a power mechanism, a right fixed seat 10, a right pulley 7, a right positioning pin 8, a right movable spindle 15, a spring 14, a right support shaft 2, and a spring and stroke adjustment mechanism. The right support shaft 2 is inserted into the inner hole of the right fixed seat 10. The right movable spindle 15 and spring 14 are located in the inner hole of the right support shaft 2. One end of the spring 14 is connected to the shaft end of the right movable spindle 15, and the other end of the spring 14 is connected to the inner wall of the inner hole of the right support shaft 2. A spring and stroke adjustment mechanism is provided on one side of the inner hole of the right fixed seat 10. The right pulley 7 is sleeved on the outside of the right fixed seat 10, and is sleeved on one side of the right fixed seat 10. A rack that cooperates with the power mechanism is provided on one side of the outer wall of the right pulley 7. The power mechanism is a synchronous belt drive or a chain drive. One side of the synchronous belt 9 or chain cooperates with the rack on the right pulley, and the other side is connected to the power mechanism, realizing that the synchronous belt or chain drives the right pulley to rotate. (Any mechanism that can drive the right pulley to rotate is a variation of the power mechanism structure, not limited to synchronous belt drive and chain drive). The right pulley 7 rotates and the right positioning pin 8 moves along the arc-shaped guide groove 18. The movement of the right positioning pin 8 simultaneously drives the right support shaft 2 to move linearly, realizing the compensation of the length of the fabric roll. The adjustment is automated by setting up a power mechanism.

[0033] The right pulley 7 is fitted with the outer circle of the right fixed seat 10. The right fixed seat 10 is fastened to the inner side of the right wall panel by screws. The outer circumferential wall of the right pulley 7 is provided with an arc-shaped guide groove 18 for guiding. The right fixed seat 10 and the right support shaft 2 are respectively provided with transverse grooves 17. The right positioning pin 8 passes through the guide groove of the right pulley, the transverse groove of the right fixed seat, and the transverse groove of the right support shaft in sequence and is threadedly fastened to the right movable spindle.

[0034] The elasticity and stroke adjustment mechanism includes an adjusting seat 11, a fastening nut 12, and an adjusting screw 13. The adjusting seat 11 is threadedly connected to the end of the right support shaft 2, and the adjusting screw 13 is threadedly connected to the adjusting seat 11. One end of the adjusting screw 13 passes through the threaded hole of the adjusting seat 11 and abuts against the end of the right movable spindle 15. The fastening nut 12 is threadedly engaged with the adjusting screw 13. A bearing seat 1 is provided on one side of the right support shaft 2. The bearing 4 and the bearing seat 1 are installed on the bearing position of the right support shaft 2 and are positioned and fixed by a shaft snap ring 3 and a hole snap ring 5. The movement of the right positioning pin 8 drives the right support shaft 2 to move. When the bearing seat 1 at the end of the right support shaft 2 is inserted into the fabric rolling roller, the adjusting screw 13 is rotated to press against the right movable spindle 15. The movement of the right movable spindle causes the spring 14 to compress a certain distance, thereby making the bearing seat 1 at the end of the right support shaft 2 securely connected to the fabric rolling roller.

[0035] One side of the right pulley 7 is provided with a right pulley positioning plate 6 for axial positioning of the right pulley. The side wall of the right pulley positioning plate 6 is provided with a threaded hole, and an oil cup 16 for lubricating the entire support device is provided in the threaded hole.

[0036] During operation, power is transmitted to the right pulley 7 via the synchronous belt 9, enabling the right pulley 7 to rotate in both directions. When the right pulley 7 rotates, it pushes the right positioning pin 8 to the left via the shaped guide groove. The right positioning pin 8, positioned by the transverse groove of the right fixed seat 10, drives the right movable spindle 15 to move to the left. The right movable spindle 15 compresses the spring 14, thereby pushing the right support shaft 2 to the left. Simultaneously, the bearing seat 1 moves to the left and inserts into the inner hole of the fabric roll, secured by the spring 14, thus supporting the fabric roll. When the right pulley 7 rotates in reverse, the bearing seat 1 moves to the right and disengages from the inner hole of the fabric roll, thus disengaging the fabric roll.
