[0001] This utility model belongs to the technical field of auxiliary devices for cotton spinning equipment, specifically relating to a device for unwinding roving on an A186 carding machine. Background Technology

[0002] In the production process of cotton spinning enterprises, to meet market demand, differentiated and functional fiber products are often produced, such as polyester, lyocell, and aramid. These fibers have characteristics such as high moisture regain, rapid moisture absorption, and significant electrostatic effects, which easily lead to substandard roving during processing. Currently, spinning mills usually directly destroy these substandard rovings as waste materials. This disposal method not only results in serious waste of raw materials but also reduces product yield, increases production costs, and causes unnecessary economic losses for enterprises.

[0003] There is a lack of a simple and easy-to-operate device in the existing technology that can effectively recycle and reuse substandard roving. Therefore, there is an urgent need to design a roving unwinding device that is compatible with the A186 carding machine to solve the above-mentioned technical problems. Summary of the Invention

This device solves the problems of direct destruction of substandard roving, which leads to waste of raw materials and low production yield. It enables the unwinding and reuse of substandard roving, thereby reducing production costs.

[0005] To achieve the above-mentioned objectives, this utility model provides a roving unwinding device for an A186 carding machine, comprising a first crossbar and a second crossbar. Z-shaped metal frames are fixedly connected to both sides of the first and second crossbars. A rod is fixedly connected to the bottom of each Z-shaped metal frame.

A first square tube is fixedly connected to the surface of the first square post, and the bottom of the first square tube is fitted against the upper surface of the first crossbar. A first roving spindle is fixedly connected to the bottom of the first square post. A second groove is formed on the front of the second crossbar, and a second square post is fitted against the inner wall of the second groove. A second square tube is fixedly connected to the surface of the second square post, and the bottom of the second square tube is fitted against the upper surface of the second crossbar. A second roving spindle is fixedly connected to the bottom of the second square post. Screws are fixedly connected to the upper surfaces of both the first and second crossbars. Fixed supports are fitted against the surface of the screws, the front and rear sides of the first and second square posts, and the surface of the screws is threaded with a nut.

[0006] Furthermore, the fixing bracket includes a rectangular ring, a hollow block, and a cylinder. The front and rear sides of the first square column and the front and rear sides of the second square column are both in contact with the inner wall of the rectangular ring. The inner wall of the rectangular ring is fixedly connected to the surface of the hollow block. The surface of the cylinder is fixedly connected to the inner wall of the hollow block. The inner wall of the cylinder is in contact with the surface of the screw. The upper and lower sides of the cylinder are respectively in contact with the upper surface of the first crossbar, the upper surface of the second crossbar, and the bottom of the nut. The upper surfaces of the first and second square cylinders are both in contact with the bottom of the rectangular ring.

[0007] Furthermore, an arc-shaped column is fixedly connected to the front of the Z-shaped metal frame.

[0008] Furthermore, a third groove is provided on the back of both the first and second square pillars. A first magnet is fixedly connected to the inner wall of the third groove, and a second magnet is fixedly connected to the inner wall of both the first and second grooves.

A first square post 6 is fitted against the inner wall of the first groove 5. A first square tube 7 is fixedly connected to the surface of the first square post 6. The bottom of the first square tube 7 is fitted against the upper surface of the first crossbar 1. A first roving spindle 8 is fixedly connected to the bottom of the first square post 6. The front of the second crossbar 2 has a second groove 9, and the inner wall of the second groove 9 is fitted with a second square post 10. The surface of the second square post 10 is fixedly connected with a second square tube 11. The bottom of the second square tube 11 is fitted with the upper surface of the second crossbar 2. The bottom of the second square post 10 is fixedly connected with a second roving spindle 12. The upper surface of the first crossbar 1 and the upper surface of the second crossbar 2 are both fixedly connected with screws 13. The surface of the screws 13, the front and rear sides of the first square post 6 and the front and rear sides of the second square post 10 are all fitted with fixed brackets 14. The surface of the screws 13 is threaded with nuts 15.

[0028] The fixed bracket 14 includes a rectangular ring 141, a hollow block 142, and a cylinder 143. The front and rear sides of the first square post 6 and the front and rear sides of the second square post 10 are both in contact with the inner wall of the rectangular ring 141. The inner wall of the rectangular ring 141 is fixedly connected to the surface of the hollow block 142. The surface of the cylinder 143 is fixedly connected to the inner wall of the hollow block 142. The inner wall of the cylinder 143 is in contact with the surface of the screw 13. The upper and lower sides of the cylinder 143 are respectively in contact with the upper surface of the first crossbar 1, the upper surface of the second crossbar 2, and the bottom of the nut 15. The upper surface of the first square cylinder 7 and the upper surface of the second square cylinder 11 are both in contact with the bottom of the rectangular ring 141.

[0029] The Z-shaped metal frame 3 is fixedly connected to an arc-shaped column 16 on the front. The first crossbar 1 is located above the second crossbar 2, and the length of the first crossbar 1 is equal to the length of the second crossbar 2.

[0030] It should be noted that the combination structure of the Z-shaped metal frame 3, the first crossbar 1, and the second crossbar 2 can be directly adapted and installed with the feed roller wall panel of the A186 carding machine without requiring major modifications to the carding machine itself. The installation is convenient and the cost is low. Furthermore, the arc-shaped column 16 can effectively prevent the roll from slipping off. At the same time, the first roving hanger 8 and the second roving hanger 12 can flexibly suspend unqualified roving. The first roving hanger 8 and the second roving hanger 12 can be used to achieve automatic unwinding of the roving. During the unwinding process, the roll can be properly layered without sticking.

[0031] The first square post 6 can be positioned by the first groove 5. After the first square post 6 is inserted into the first groove 5, the first square tube 7 prevents the first square post 6 from slipping out of the first groove 5. The second square post 10 can be positioned by the second groove 9. After the second square post 10 is inserted into the second groove 9, the second square tube 11 prevents the second square post 10 from slipping out of the second groove 9.

[0032] After the nut 15 is screwed onto the screw 13, the fixing bracket 14 can be fixed onto the first crossbar 1 or the second crossbar 2 through the cooperation of the screw 13, the nut 15 and the cylinder 143. When the nut 15 is separated from the screw 13, the fixing bracket 14 can be directly removed from the first crossbar 1 or the second crossbar 2.

[0033] After the fixed bracket 14 is fixed on the first horizontal bar 1, the first roving spindle 8 can be fixed on the first horizontal bar 1 through the cooperation of the first groove 5, the first square column 6, the first square tube 7 and the rectangular ring 141. When the fixed bracket 14 is separated from the first horizontal bar 1, the multiple first roving spindles 8 can be directly taken off from the first horizontal bar 1.

[0034] After the fixed bracket 14 is fixed on the second crossbar 2, the second roving spindle 12 can be fixed on the second crossbar 2 by the cooperation of the second groove 9, the second square column 10, the second square tube 11 and the rectangular ring 141. When the fixed bracket 14 is separated from the second crossbar 2, multiple second roving spindles 12 can be directly taken off the second crossbar 2.

[0035] A third groove 17 is provided on the back of the first square post 6 and the back of the second square post 10. A first magnet 18 is fixedly connected to the inner wall of the third groove 17. A second magnet 19 is fixedly connected to the inner wall of the first groove 5 and the inner wall of the second groove 9. The back of the first magnet 18 is in contact with the front of the second magnet 19.

[0036] The center of the first magnet 18 and the center of the second magnet 19 are on the same horizontal line. The back of the first magnet 18 is the N pole, and the front of the second magnet 19 is the S pole.

[0037] It should be noted that when the first square post 6 is placed in the first groove 5, the attraction force of the first magnet 18 on the second magnet 19 can align the multiple first square posts 6, making it easier for the user to put the rectangular ring 141 on the fixing bracket 14 onto the multiple first square posts 6. When the second square post 10 is placed in the first groove 5, the attraction force of the first magnet 18 on the second magnet 19 can align the multiple second square posts 10, making it easier for the operator to put the rectangular ring 141 on the fixing bracket 14 onto the multiple second square posts 10.

[0038] The working principle of this utility model is as follows: First, the bottom surface of the Z-shaped metal frame 3 is welded and fixed to the insertion rod 4 of the cotton feeding roller wall panel of the A186 carding machine, thus completing the overall installation and positioning of the device.

[0039] Then, insert the required number of first square posts 6 into the first grooves 5 at the designated positions. At this time, the first square tube 7 prevents the first square posts 6 from falling off, and the attraction of the first magnet 18 to the second magnet 19 allows the multiple first square posts 6 to be aligned. Then, put the rectangular ring 141 on the multiple first square posts 6 and put the cylinder 143 on the screw 13. Then, screw the nut 15 on the screw 13. At this time, through the cooperation of the screw 13, nut 15 and cylinder 143, the rectangular ring 141 is fixed on the first crossbar 1. And through the cooperation of the first groove 5, the first square posts 6, the first square tube 7 and the rectangular ring 141, the first roving spindle 8 can be fixed on the first crossbar 1.

[0040] Then, insert the required number of second square posts 10 into the second grooves 9 at the designated positions. At this time, the second square tube 11 prevents the second square posts 10 from falling off, and the attraction of the first magnet 18 to the second magnet 19 aligns the multiple second square posts 10. Then, put the rectangular ring 141 on the multiple second square posts 10 and put the cylinder 143 on the screw 13. Then, screw the nut 15 on the screw 13. At this time, the rectangular ring 141 is fixed on the second crossbar 2 by the cooperation of the screw 13, the nut 15 and the cylinder 143. The second roving spindle 12 can be fixed on the second crossbar 2 by the cooperation of the second groove 9, the second square posts 10, the second square tube 11 and the rectangular ring 141.

[0041] The substandard roving is suspended on either the first roving spindle 8 or the second roving spindle 12. The roll is placed on the Z-shaped metal frame 3, and the arc-shaped column 16 prevents the roll from falling. Then, the A186 carding machine is started. When the cotton roller rotates, it drives the roving sliver to unwind automatically. During the unwinding process, the roll is normally separated into layers without sticking. The unwound roving sliver and the cotton roll enter the carding machine licker-in roller together. After being opened into single fibers by the licker-in roller, they are fully mixed with the cotton roll fibers to finally produce a uniform and qualified cotton sliver for use in subsequent processes.

[0042] When disassembling the first roving spindle 8, first unscrew the nut 15 from the screw 13, and then remove the rectangular ring 141 from the first crossbar 1 to remove the multiple first roving spindles 8 from the first crossbar 1. When disassembling the second roving spindle 12, first unscrew the nut 15 from the screw 13, and then remove the rectangular ring 141 from the second crossbar 2 to remove the multiple second roving spindles 12 from the second crossbar 2.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
