Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, specifically relating to a heavy-duty canvas winding auxiliary device. Background Technology

[0002] The canvas winding equipment includes two frames arranged opposite each other. Bearing seats are respectively provided on the two frames. The bearings on the two bearing seats are equipped with chucks, and a rotating shaft is provided between the bearings. The rotating shaft passes through the canvas roll and its two ends are detachably fixed to the chucks. One of the bearings of the frame is connected to the motor through a gearbox. The rotation of the motor drives the bearing to rotate, thereby driving the canvas roll to rotate and realize the canvas winding.

[0003] However, since the canvas roll weighs 2-3 tons and has a wide range of widths, the narrower the width, the greater the gravity on the middle of the shaft, which can easily cause the shaft to deform. This makes it difficult for the motor to drive the canvas roll to rotate at a constant speed and rewind. In addition, after a period of use, the more severe the deformation in the middle of the shaft, the more likely the chucks at both ends of the shaft will deform and fail to fit into the chuck, requiring frequent replacement and increasing material and maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a heavy-duty canvas winding auxiliary device.

[0005] The technical solution adopted by this utility model is a heavy-duty canvas winding auxiliary device, including a crossbar and pull straps symmetrically suspended at both ends of the crossbar. The lower part of the pull strap is connected to a rolling bearing, and the inner ring of the rolling bearing is fixedly connected to a drive shaft. The inner end of the drive shaft is connected to a tube that passes through the canvas roll, and the outer end is connected to a bushing. The outer end of the bushing has a through hole and is connected to the head end of the chuck shaft by a bolt through the through hole. The end of the chuck shaft is bolted to the chuck. The middle of the top of the crossbar is connected to a suspension mechanism through a connecting ear plate. The suspension mechanism lifts the crossbar to tighten the pull straps and apply an upward pulling force to the rolling bearing.

[0006] Preferably, the distance from the rolling bearing to the cylinder is 5-10 cm.

[0007] Preferably, the inner end of the bushing is integrally formed with the drive shaft, and the through hole at the outer end of the bushing is a square hole. The chuck shaft is inserted into the bushing through the square hole. Multiple positioning holes are provided on the bushing, and bolts are used to fix the bushing and the chuck shaft through the positioning holes.

[0008] Preferably, the suspension mechanism includes a pull rope, a movable pulley, and a hook. The pull rope passes over the movable pulley and its two ends are connected upward to a winch. A fixed plate is provided below the movable pulley. The fixed plate is hinged to the hook, and the lower end of the hook is attached to a connecting ear plate.

[0009] Preferably, two limiting rods are provided at intervals at the top of each end of the crossbar, the main body of the pull belt is in the shape of a flat strip, and annular collars are provided at both ends. After the middle part of the pull belt passes over the lower part of the rolling bearing, the annular collars at both ends are suspended between the two limiting rods.

[0010] Preferably, the inner end of the aforementioned drive shaft is engaged with the cylinder.

[0011] Compared to existing technologies, the advantages of this invention are as follows: A suspension mechanism is installed above the heavy-duty canvas roll, connecting two straps via a crossbar to suspend a rolling bearing. The inner ring of the rolling bearing houses a drive shaft, which is connected to a chuck shaft and the roll via a bushing. Without affecting the motor's drive of the drive shaft to rotate the roll, the suspension mechanism raises the straps to maintain an upward pull on the rolling bearing (drive shaft). This prevents excessive weight from the canvas roll causing downward force on the drive shaft, which could deform and hinder the uniform rotation of the canvas roll. Simultaneously, it reduces deformation at both ends, ensuring a secure connection with the chuck. Furthermore, the bushing connection between the drive shaft and the chuck shaft not only facilitates removal of the canvas roll after winding but also allows for individual replacement of deformed or damaged parts, simplifying the loading and unloading process and saving material costs.

[0013] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0014] Example 1 like Figure 1-2As shown, a heavy-duty canvas winding auxiliary device includes a crossbar 1 and pull straps 2 symmetrically suspended at both ends of the crossbar 1. The lower part of the pull straps 2 is connected to a rolling bearing 3, and the inner ring of the rolling bearing 3 is fixedly connected to a drive shaft 4. Both ends of the drive shaft 4 extend out of the rolling bearing 3 and can rotate within the rolling bearing 3. The inner end of the drive shaft 4 is connected to a tube 6 that passes through a canvas roll 5. The outer end of the drive shaft 4 is connected to a bushing 7. The outer end of the bushing 7 has a through hole and is bolted to the head end of a chuck shaft 8. The end of the chuck shaft 8 is bolted to a chuck 9. A connecting ear plate 10 is connected to the middle of the top of the crossbar 1. The suspension mechanism connects to the lifting crossbar 1, which tightens the strap 2 and applies an upward pulling force to the rolling bearing 3. This prevents the excessive weight of the canvas after it has been wound too much from causing a downward force on the drive shaft, which would deform the drive shaft and hinder the uniform rotation of the canvas roll. At the same time, it reduces the degree of deformation at both ends to ensure a stable connection with the chuck. The bushing connecting the drive shaft and the chuck shaft not only allows for easy removal of the canvas roll after winding, but also enables individual replacement of deformed or damaged parts, simplifying the loading and unloading process and saving material costs.

[0015] Furthermore, the distance between the aforementioned rolling bearing 3 and the bobbin 6 is 5-10cm to ensure sufficient support for the drive shaft and prevent damage to the drive shaft from the weight of the canvas; in order to facilitate the connection and removal of the canvas roll, the inner end of the drive shaft 4 is engaged with the bobbin 6.

[0016] The inner end of the aforementioned bushing 7 is integrally formed with the drive shaft 4. The through hole at the outer end of the bushing 7 is a square hole. The chuck shaft 8 is inserted into the bushing 7 through the square hole. Multiple positioning holes are provided on the bushing 7. Bolts are used to fix the bushing 7 and the chuck shaft 8 through the positioning holes. When the winding is completed, by disassembling the connection between the chuck shaft 8 and the bushing 7, the canvas roll can be directly hoisted to the set position using the suspension mechanism, and then the connection between the drive shaft 4 and the tube 6 can be loosened.

[0017] Preferably, the suspension mechanism includes a pull rope 11, a movable pulley 12, and a hook 13. The pull rope 11 passes around the movable pulley 12 and its two ends are connected upward to the winch 14. A fixing plate 15 is provided below the movable pulley 12. The fixing plate 15 is hinged to the hook 13, and the lower end of the hook 13 is attached to the connecting ear plate 10.

[0018] Furthermore, two limiting rods 16 are provided at intervals at the top of both ends of the crossbar 1. The main body of the pull belt 2 is flat and strip-shaped, with annular collars at both ends. After the middle of the pull belt 1 passes over the lower part of the rolling bearing 3, the annular collars at both ends are suspended between the two limiting rods 16. The limiting rods 11 can limit the position of the pull belt, prevent the pull belt from deviating, and ensure that a vertical upward pulling force is applied to the rolling bearing.

[0019] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
