[0014] Compared with the prior art, the beneficial effects of this utility model are: the friction roller for texturing machine not only improves the working efficiency of the friction roller when positioning and placing the paper tube, and improves the convenience of connecting the friction roller with the rotating shaft, but also improves the stability of the friction roller during use.

[0015] 1. By setting a positioning mechanism, the paper tube is fitted onto the surface of the friction roller body, so that the paper tube contacts the stop block. Then, the paper tube is rotated, causing the paper tube to drive the slot to rotate. When the slot rotates to the side of the stop block, the paper tube is positioned and fixed by the interlocking action of the stop block and the slot. Since the positioning screw hole and the positioning insertion hole coincide when the stop block and the slot are engaged, the positioning screw hole and the positioning insertion hole can be quickly positioned and aligned. Then, the screw that matches the positioning screw hole is inserted into the positioning insertion hole, and the screw is rotated. With the thread engagement between the screw and the positioning screw hole, the paper tube is quickly fixed to the friction roller body, so as to realize the function of quick positioning and placement of the paper tube by the friction roller, thereby improving the working efficiency of the friction roller in positioning and placing the paper tube.

[0016] 2. By setting a connecting mechanism, the connecting shaft is placed on one side of the rotating shaft, and then the pin block is pulled to retract into the receiving groove so that the pin block does not affect the rotation of the rotating shaft. Then, the fixing stud is inserted into the threaded hole, and then the friction roller body is used to drive the connecting shaft to rotate, which in turn drives the fixing stud to rotate. The rotating shaft and the connecting shaft are fastened together by the threaded engagement between the threaded hole and the fixing stud. Then, the pin block is released. Since the pin block and the pin groove are engaged when the fixing stud is fastened to the threaded hole, the pin block moves into the pin groove under the elastic force of the extension spring, thus fastening the rotating shaft and the connecting shaft together. This realizes the function of connecting the friction roller to the rotating shaft, thereby improving the convenience of connecting the friction roller and the rotating shaft.

[0017] 3. With the auxiliary support mechanism, before installing the friction roller, the connecting plate can be sleeved onto the outside of the connecting shaft and fixed to the surface of the friction roller bracket with screws. Then, the length of the telescopic rod is adjusted so that one end of the telescopic rod is inserted into the annular groove, so that the balls contact the inner wall of the annular groove. When the friction roller rotates, it drives the annular groove to rotate along the telescopic rod. Under the action of the telescopic rod, the annular groove can be auxiliary supported, and the friction roller can be supported, so as to realize the auxiliary support function of the friction roller, thereby improving the stability of the friction roller during use.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] This utility model provides a structure for a friction roller in a texturing machine, as shown below. Figure 1 and Figure 4 As shown, the device includes a friction roller body 1, a paper tube 11 sleeved on the surface of the friction roller body 1, a connecting shaft 13 fixed on the surface of the friction roller body 1, the central axis of the connecting shaft 13 coinciding with the central axis of the friction roller body 1, a rotating shaft 12 on one side of the connecting shaft 13, and auxiliary support mechanisms 2 at both ends of the friction roller body 1. The auxiliary support mechanism 2 consists of a connecting plate 21, a telescopic rod 22, an annular groove 23, and a ball bearing 24. A connecting plate 21 is provided at both ends of the friction roller body 1, and a telescopic rod 22 is fixed on the surface of the connecting plate 21. A ball bearing 24 is embedded in the bottom of the telescopic rod 22. An annular groove 23 is provided at both ends of the friction roller body 1. The annular groove 23 and the ball bearing 24 rotate and cooperate with each other. The central axis of the annular groove 23 coincides with the central axis of the friction roller body 1.

[0025] In use, before installing the friction roller body 1, the connecting plate 21 can be sleeved onto the outside of the connecting shaft 13, and the connecting plate 21 can be fixed to the support surface of the friction roller with screws. Then, adjust the length of the telescopic rod 22 so that one end of the telescopic rod 22 is inserted into the annular groove 23, so that the ball 24 contacts the inner wall of the annular groove 23. When the friction roller body 1 rotates, it drives the annular groove 23 to rotate along the telescopic rod 22. Under the action of the telescopic rod 22, the annular groove 23 can be auxiliary supported, and the friction roller body 1 can be supported, so as to realize the auxiliary support function of the friction roller.

[0026] Furthermore, such as Figure 2As shown, a positioning mechanism 3 is provided on the surface of the friction roller body 1 and the paper tube 11. The interior of the positioning mechanism 3 includes a positioning insertion hole 31, a slot 32, a locking block 33, a positioning screw hole 34, and a stop block 35. The stop block 35 is fixed on the surface of the friction roller body 1, and the surface of the stop block 35 is in close contact with the surface of the paper tube 11. Slots 32 are provided on both sides of the surface of the paper tube 11, and locking blocks 33 are fixed on both sides of the surface of the friction roller body 1. The locking blocks 33 and the slots 32 are engaged with each other. Positioning screw holes 34 are provided on both sides of the surface of the friction roller body 1, and positioning insertion holes 31 are provided on both sides of the paper tube 11. When the locking block 33 engages with the slot 32, the positioning insertion hole 31 and the positioning screw hole 34 coincide.

[0027] In use, the paper tube 11 is fitted onto the surface of the friction roller body 1, so that the paper tube 11 contacts the stop block 35. Then, the paper tube 11 is rotated, causing the paper tube 11 to drive the slot 32 to rotate. When the slot 32 rotates to the side of the block 33, the paper tube 11 is positioned and fixed under the interlocking action of the block 33 and the slot 32. Since the positioning screw hole 34 and the positioning insertion hole 31 coincide when the block 33 and the slot 32 are engaged, the positioning screw hole 34 and the positioning insertion hole 31 can be quickly positioned and aligned. Then, the screw that matches the positioning screw hole 34 is inserted into the positioning insertion hole 31, and the screw is rotated. Under the thread engagement of the screw and the positioning screw hole 34, the paper tube 11 is quickly fixed to the friction roller body 1, so as to realize the function of quick positioning and placement of the paper tube 11 by the friction roller.

[0028] Furthermore, such as Figure 3 As shown, the rotating shaft 12 and the connecting shaft 13 are detachably connected via a connecting mechanism 4. The connecting mechanism 4 consists of a fixing stud 41, a pin-locking assembly 42, and a threaded hole 43. One end of the connecting shaft 13 is fixed with the fixing stud 41, and one end of the rotating shaft 12 has a threaded hole 43. The threaded hole 43 is threadedly fastened to the fixing stud 41. A pin-locking assembly 42 is provided between the rotating shaft 12 and the connecting shaft 13. The pin-locking assembly 42 contains a pin groove 421, a pin block 422, a extension spring 423, and... The receiving groove 424 has a pin groove 421 on one side of the rotating shaft 12 and a receiving groove 424 on one side of the connecting shaft 13. A pin block 422 is provided inside the receiving groove 424. The pin block 422 and the receiving groove 424 slide with each other. When the fixing stud 41 is tightened with the threaded hole 43, the pin block 422 and the pin groove 421 are pinned together. One end of the pin block 422 is fixed with a tension spring 423. One end of the tension spring 423 is fixedly connected to the inner wall of the receiving groove 424.

[0029] In use, place the connecting shaft 13 on one side of the rotating shaft 12, then pull the pin block 422 to retract it into the receiving groove 424 so that the pin block 422 does not affect the rotation of the rotating shaft 12. Then insert the fixing stud 41 into the threaded hole 43, and then rub the roller body 1 to make the friction roller body 1 drive the connecting shaft 13 to rotate, and the connecting shaft 13 drives the fixing stud 41 to rotate. Under the threaded engagement of the threaded hole 43 and the fixing stud 41, the rotating shaft 12 and the connecting shaft 13 are fastened. Then loosen the pin block 422. Since the pin block 422 and the pin groove 421 are engaged when the fixing stud 41 and the threaded hole 43 are fastened, the pin block 422 moves into the pin groove 421 under the elastic force of the extension spring 423, and fastens the rotating shaft 12 and the connecting shaft 13, so as to realize the function of the friction roller to easily connect the rotating shaft 12.

[0030] Working principle: In use, first, the paper tube 11 is fitted onto the surface of the friction roller body 1, so that the paper tube 11 contacts the stop block 35. Then, the paper tube 11 is rotated, causing the paper tube 11 to drive the slot 32 to rotate. When the slot 32 rotates to the side of the block 33, the paper tube 11 is positioned and fixed under the interlocking action of the block 33 and the slot 32. Since the positioning screw hole 34 and the positioning insertion hole 31 coincide when the block 33 and the slot 32 are engaged, the positioning screw hole 34 and the positioning insertion hole 31 can be quickly positioned and aligned. Then, the screw that matches the positioning screw hole 34 is inserted into the positioning insertion hole 31, and the screw is rotated. Under the thread engagement of the screw and the positioning screw hole 34, the paper tube 11 is quickly fixed to the friction roller body 1, so as to realize the function of quick positioning and placement of the paper tube 11 by the friction roller, thereby improving the working efficiency of the friction roller in positioning and placing the paper tube 11.

[0031] Then, the connecting shaft 13 is placed on one side of the rotating shaft 12. Then, the pin block 422 is pulled to retract into the receiving groove 424 so that the pin block 422 does not affect the rotation of the rotating shaft 12. Then, the fixing stud 41 is inserted into the threaded hole 43. Then, the friction roller body 1 is rubbed to make the friction roller body 1 drive the connecting shaft 13 to rotate, and the connecting shaft 13 drives the fixing stud 41 to rotate. Under the threaded engagement of the threaded hole 43 and the fixing stud 41, the rotating shaft 12 and the connecting shaft 13 are fastened. Then, the pin block 422 is released. Since the pin block 422 and the pin groove 421 are engaged when the fixing stud 41 and the threaded hole 43 are fastened, the pin block 422 moves into the pin groove 421 under the elastic force of the extension spring 423, and the rotating shaft 12 and the connecting shaft 13 are fastened. This realizes the function of connecting the friction roller to the rotating shaft 12, thereby improving the convenience of connecting the friction roller and the rotating shaft 12.

[0032] Before installing the friction roller body 1, the connecting plate 21 can be fitted onto the outside of the connecting shaft 13, and the connecting plate 21 can be fixed to the support surface of the friction roller with screws. Then, adjust the length of the telescopic rod 22 so that one end of the telescopic rod 22 is inserted into the annular groove 23, so that the ball 24 contacts the inner wall of the annular groove 23. When the friction roller body 1 rotates, it drives the annular groove 23 to rotate along the telescopic rod 22. Under the action of the telescopic rod 22, the annular groove 23 can be auxiliary supported, and the friction roller body 1 can be supported to realize the auxiliary support function of the friction roller, thereby improving the stability of the friction roller during use, and finally completing the use of the friction roller.
