Description

Technical Field

[0001] This utility model belongs to the field of spinning technology, specifically to a simple drawing device for disassembling a conical mating roller. Background Technology

[0002] In the spinning industry, drawing machines are frequently used. The most important aspect of drawing machines is the runout requirement of the roller surface. Therefore, the equipment needs to be debugged and disassembled. Currently, most drawing rollers rely on the conical surface on the roller shaft to cooperate and transmit torque. However, when the roller shaft conical surface is fully pressed together, it is very difficult to disassemble the roller shaft due to space limitations and to ensure that the roller surface is not scratched. Summary of the Invention

[0003] The present invention mainly addresses the technical problems existing in the prior art and provides a simple pulling device for disassembling tapered mating rollers.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A simple pulling device for disassembling a conical roller shaft includes a base plate and a top plate. The base plate has a slot at its center, with the slot opening facing downwards. Three screws are connected between the base plate and the top plate. The right ends of the three screws are threaded and distributed around the slot, and are all fixedly connected to the base plate. Through holes are provided on the top plate at positions corresponding to the three screws. The top plate passes through the three screws through the through holes. A locking nut is provided on each of the screws on the left and right sides of the top plate. The locking nut is connected to the threaded structure of the screw. A rotating seat is provided at the center of the top plate. A bolt is provided in the rotating seat and is threadedly connected to the rotating seat. The end of the bolt away from the base plate is hexagonal. A transverse rotating rod passes through the bolt on the left side of the hexagonal structure and is slidably connected to the bolt.

[0005] The inner side of the slot is arc-shaped.

[0006] The top plate around the rotating base has multiple slots.

[0007] The end of the bolt near the base plate is flat.

[0008] The end of the bolt near the base plate is tapered.

[0009] The beneficial effects of this utility model are as follows: by setting a bottom plate and a top plate, the slot on the bottom plate is used to lock onto the end face of the drawing roller, and the drawing roller can be pulled off the roller shaft by rotating the bolts without damaging the surface of the drawing roller; by using three screws evenly distributed around the slot, the bottom plate can be subjected to more uniform force during the pulling process, so that the end face of the drawing roller is subjected to uniform force, and the drawing roller can be pulled off the roller shaft more easily.

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example: A simple pulling device for disassembling tapered mating rollers, such as... Figures 1-4 As shown, the device includes a base plate 1 and a top plate 2. The base plate 1 has a slot 3 at its center, with the slot opening facing downwards. Three screws 4 connect the base plate 1 and the top plate 2. The right ends of the three screws 4 are threaded structures 5, distributed around the slot 3 and fixedly connected to the base plate 1. Through holes 6 are provided on the top plate 2 at positions corresponding to the three screws 4. The top plate 2 passes through the through holes 6 onto the three screws 4. A locking nut 7 is provided on each of the screws 4 on both the left and right sides of the top plate 2, and the locking nut 7 is connected to the threaded structure 5 of the screw 4. A rotating seat 8 is located at the center of the top plate 2, and a bolt 9 is provided in the rotating seat 8. The bolt 9 is threadedly connected to the rotating seat 8. The end of the bolt 9 away from the base plate 1 has a hexagonal structure 10. A transverse rotating rod 11 passes through the bolt 9 on the left side of the hexagonal structure 10, and the transverse rotating rod 11 is slidably connected to the bolt 9.

[0017] The inner side of the slot 3 is arc-shaped; multiple slots 12 are provided on the top plate 2 around the rotating seat 8.

[0018] The end of the bolt 9 near the base plate 1 is flat; the end of the bolt 9 near the base plate 1 is tapered.

[0019] The principle of this utility model: In use, such as Figure 2 As shown, the device is fitted onto the drafting roller from top to bottom, and secured to the roller shaft through the opening slot on the base plate 1. The base plate 1 is placed against the end face of the drafting roller. By rotating the bolt 9, the inner end of the bolt 9 is placed against the end face of the roller shaft. The bolt 9 is rotated by the transverse rotating shaft on the bolt 9, and the drafting roller is pulled out from the surface of the roller shaft by the reverse pulling force. When the end face of the roller shaft has a center hole, the end of the bolt 9 can be selected as a tapered bolt 9, which is convenient to fix in the center of the roller shaft. If the drafting roller cannot be pulled out by rotating the bolt 9 by the transverse rotating rod 11, the hexagonal structure 10 on the bolt 9 can be rotated by a wrench to increase the torque and facilitate the removal of the drafting roller from the rotating shaft.

[0020] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
