Description

Technical Field

[0001] The utility model relates to the technical field of doubling twisting machines, in particular to a yarn protection frame for a doubling twisting machine. Background Technique

[0002] A doubling twisting machine is a twisting device, which is essentially a wire drawing machine called a wire drawing machine. It can achieve two twists in one rotation. The twisting efficiency is increased several times compared with traditional twisting equipment. The winding capacity is increased, there is no joint per ten thousand meters, the twisting quality is greatly improved, and the floor height is relatively low, which is particularly suitable for operation.

[0003] According to a doubling twisting and hank yarn integrated machine disclosed in the publication number CN109881307B, which includes a doubling twisting machine, a conveying frame, a guide rod and a hank yarn device. A conveying frame is installed at the upper end of the doubling twisting machine. The guide rod is located at the upper end of the conveying frame. The conveying frame is connected to the doubling twisting machine. The hank yarn device is installed on the top of the doubling twisting machine. Yarn is wound on the doubling twisting machine. The yarn can be wound on the hank yarn device under the action of the conveying frame and the guide rod; the hank yarn device includes a base, a belt pulley, a bearing seat, a hank yarn disc, a hank yarn rod, a spring, a rotating shaft, a linkage rod and a moving disc; an external thread is provided at the right end of the rotating shaft, and a nut is provided at the right end of the rotating shaft in a threaded connection manner. The integrated operation of doubling twisting and hank yarn is beneficial to obtaining a relatively loose formed yarn; the hank yarn structure is simple, easy to operate and convenient for doffing; the yarn is positioned and guided during yarn transmission.

[0004] However, the above technology does not solve the problem of excessive tension or relaxation of the yarn during use. Excessive tension or relaxation of the yarn will cause the phenomenon of yarn breakage or knotting. When the machine stops, the yarn will rebound, causing the yarn bobbin to rotate in the reverse direction and resulting in yarn knotting. For this reason, we provide a yarn protection frame for a doubling twisting machine to solve the above problems. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] The purpose of the utility model is to make up for the deficiencies of the existing technology and provide a yarn protection frame for a doubling twisting machine.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the present utility model provides the following technical solution: A yarn protection frame for a doubling frame, comprising a housing and a chamber opened in the housing. A pair of symmetrically arranged chutes are opened above the interior of the chamber. Slide bars are arranged in the chutes. Sliders that slide in the chutes are sleeved on the surfaces of the slide bars. Springs are sleeved on the surfaces of the slide bars, and the springs are arranged between two adjacent sliders. An active rod is fixed to the side surface of the slider, and a wire guide wheel is arranged on the surface of the active rod. A groove is opened at the bottom end of the chamber, and a ratchet mechanism is arranged in the groove. A protective barrel is arranged in the chamber, and a support rod is arranged in the protective barrel.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figure 1-6As shown in the figure, the utility model provides a technical solution: a yarn protection frame for a doubling frame, which includes a housing 1 and a chamber 5 opened in the housing 1. Above the interior of the chamber 5, symmetric left and right chutes 8 are opened. A slide bar 10 is arranged in the chute 8. A plurality of sliders 9 that slide in the chute 8 are sleeved on the surface of the slide bar 10. A spring 11 is sleeved on the surface of the slide bar 10, and the spring 11 is arranged between two adjacent sliders 9. A movable rod 7 is fixed to the side surface of the slider 9. A wire guide pulley 6 is arranged on the surface of the movable rod 7. A groove 21 is opened at the bottom end of the chamber 5. A ratchet mechanism 18 is arranged in the groove 21. A protection barrel 12 is arranged in the chamber 5. A support rod 14 is arranged in the protection barrel 12. The bottom end of the support rod 14 passes through the protection barrel 12 and is connected to the ratchet mechanism 18 in the groove 21. Above the support rod 14, a wire coil 15 is arranged. The yarn will pass through the wire coil 15 and be wound and sent out on the wire guide pulley 6. By using the elastic force of the spring 11 between the plurality of sliders 9, when the yarn is tightened, the wire guide pulley 6 on the surface of the movable rod 7 will move relatively. When the yarn is slack, under the elastic force of the spring 11, the wire guide pulley 6 will move away from each other and support the yarn, so as to avoid excessive tightening and slackening of the yarn and protect the yarn from breaking due to the tension during the process of the yarn routing.

[0026] Specifically, as Figure 1 shown, a protection door 2 is movably connected to the surface of the housing 1 through a hinge 4, and a handle 3 is arranged on the surface of the protection door 2, which can use the hinge 4 and the protection door 2 to protect the yarn in the housing 1 and prevent personnel from touching the yarn when the doubling frame yarn is working.

[0027] Specifically, as Figure 6 shown, the ratchet mechanism 18 includes a connecting block 181, a fixed block 182, a stop rod 183 and a stop block 184. The connecting block 181 is clamped with the bottom end of the support rod 14. Stop blocks 184 are fixedly arranged on the surface of the connecting block 181. The fixed block 182 is fixed on the inner wall of the groove 21. The fixed block 182 is connected to the stop rod 183 through a pin shaft. A return spring piece is sleeved on the pin shaft surface between the fixed block 182 and the stop rod 183, and the number of the stop rods 183 is adapted to the number of the stop blocks 184. Through the ratchet mechanism 18, when the yarn reel on the surface of the support rod 14 rotates and pays out the line, it can pay out the line in a single direction. By using the spring 11 sleeved on the pin shaft surface between the fixed block 182 and the stop rod 183, synchronous rotation is realized when the stop block 184 rotates. At the same time, the limit between the stop rod 183 and the fixed block 182 can also prevent the overall ratchet mechanism 18 from rotating in the reverse direction and prevent the yarn from being pulled and broken.

[0028] Specifically, an annular groove 19 is formed at the bottom end of the chamber 5, and balls 20 are arranged in the annular groove 19. The surface of the balls 20 abuts against the bottom end of the protective barrel 12. A limiting groove 13 is formed in the protective barrel 12, and a limiting block 17 is arranged in the limiting groove 13. A limiting rod 16 is fixed to the side of the limiting block 17, and the limiting rod 16 is fixed to the support rod 14. By providing the annular groove 19 and the balls 20, an operator can replace the protective barrel 12 of different sizes as needed, thereby realizing the protection of the yarn bobbin. At the same time, the use of the limiting block 17 and the limiting rod 16 on the protective barrel 12 can fix the support rod 14, and the support rod 14 is used to fix the yarn bobbin in the protective barrel 12, and the support rod 14 is clamped on the ratchet mechanism 18 to drive the protective barrel 12 to rotate together when rotating.

[0029] Working principle: During use, a staff member opens the protective door 2 through the handle 3, connects the protective barrel 12 with the yarn bobbin to the annular groove 19 formed at the bottom end of the chamber 5 through the balls 20 at the bottom end. After installation, the support rod 14 is passed through the yarn bobbin in the protective barrel 12 and clamped to the ratchet mechanism 18. At the same time, the upper limiting block 17 is clamped into the limiting groove 13 in the protective barrel 12. Then, the yarn is passed through the wire guiding coil 15 above the support rod 14 and wound around a plurality of wire guiding wheels 6 and pulled out for external connection. Finally, the protective door 2 is closed. When the yarn is routed, the wire guiding wheels 6 will adjust the distance between the wire guiding wheels 6 according to the tension of the yarn through the movable rod 7, the slider 9 and the matching spring 11, avoiding yarn breakage or loose knotting. When the yarn bobbin needs to be replaced, it can be replaced in the above manner.
