[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model discloses a roving machine yarn storage track correction device, including a correction frame 1, and the correction frame 1 includes a first frame body 11 and a second frame body 12 hingedly arranged on the first frame body 11, the first frame body 11 and the second frame body 12 are connected in a V shape, and an expansion device is arranged on the correction frame 1, and the expansion device is used to expand the first frame body 11 and the second frame body 12 in the correction frame 1. When in use, the first frame body 11 and the second frame body 12 are rotated and their angles are expanded through the expansion device to open the two side walls of the elbow track.

[0024] In one embodiment, a guide groove 5 arranged in an inclined shape is provided on one side of the second frame 12 away from the hinged connection with the first frame 11, and the lower end of the guide groove 5 faces the side where the second frame 12 is connected to the first frame 11, and the higher end faces the other side of the second frame 12 away from the connection with the first frame 11. A mounting rod 6 is slidably inserted in the guide groove 5, and a pulley group 7 with a diameter larger than the width of the second frame 12 is rotatably provided on the mounting rod 6. The pulley group 7 consists of an assembly frame and a plurality of pulley bodies rotatably installed in the assembly frame and with the same rotation direction. The rotation direction of each pulley body is consistent with the movement direction of the belt or chain. The assembly frame is rotatably connected to the mounting rod 6, and a limiting device 8 is installed on the second frame 12. The limiting device 8 is used to block the mounting rod 6 from moving to the two ends of the guide groove 5 so that the mounting rod 6 is locked and limited.

[0025] In the specific implementation, the correction frame 1 is first placed in the elbow track of the roving machine. At this time, the belt or chain is located between the first frame 11 and the second frame 12. Then, the first frame 11 and the second frame 12 are rotated and unfolded through the expansion device, and the first frame 11 and the second frame 12 are unfolded to the side where the first frame 11 and the second frame 12 are away from each other and respectively contact the inner walls of the elbow track. As the unfolding continues, the two side walls with smaller openings at the elbow track can be enlarged by the correction frame 1 whose angle has been adjusted to ensure smooth passage of the belt or chain.

[0026] At the same time, the mounting rod 6 is first located at the higher end of the guide groove 5, so the pulley block 7 will protrude from the surface of the second frame 12 and contact the inner wall of the elbow track. With this design, when the correction frame 1 is placed inside the elbow track and is in a supporting state, the position of the correction frame 1 can be manually fine-tuned by sliding the pulley block 7 with the inner wall of the elbow track, without the need to repeatedly control and reduce the expansion angle of the correction frame 1 for adjustment, thereby making the adjustment of the device more accurate and convenient. After the position adjustment is completed, the mounting rod 6 is moved to the lower end of the guide groove 5, and the pulley block 7 moves synchronously at this time, so that the pulley block 7 can be adjusted to adjust the position of the correction frame 1. The surface of the group 7 protrudes to the side of the second frame 12 close to the first frame 11. After the position adjustment is completed, the mounting rod 6 at the corresponding position can be limited by the limit device 8. When the correction frame 1 expands the elbow track and the belt or chain is in the conveying state, the belt or chain may contact the second frame 12 and be worn during operation. Therefore, when the surface of the pulley group 7 protrudes to the side of the second frame 12 close to the first frame 11, the belt or chain will only contact the pulley body in the pulley group 7, thereby preventing the belt or chain from being worn and making the belt or chain move more smoothly.

[0027] When the second frame 12 is adjusted to any angle, the pulley block 7 can be rotated to be parallel to the belt or sprocket, thereby ensuring normal operation when the belt or sprocket contacts the pulley block 7. In actual situations, the pulley block 7 and the corresponding structure can also be set on the first frame 11 to further improve the safety of operation.

[0028] In one embodiment, the outer shape of the second frame body 12 is in a shape of a reverse slash, an adjustment opening is provided at its inclined end, the guiding groove 5 is provided at the straight end of the second frame body 12, and the expansion device includes a strip-shaped groove 13 provided at the inclined end of the second frame body 12 and cooperating with the adjustment opening. The strip-shaped groove 13 is arranged along the length direction of the inclined end of the second frame body 12. An installation sleeve 2 is rotatably installed on the first frame body 11, a threaded rod 3 is rotatably installed on the installation sleeve 2, a threaded sleeve 4 is arranged on the outer side of the threaded rod 3 and cooperates with it, and the threaded sleeve 4 is rotatably and slidably arranged on the strip-shaped groove 13.

[0029] With such a design, when the threaded rod 3 rotates, it will cause the threaded sleeve 4 to move linearly on its surface. At this time, the second frame body 12 will rotate and adjust with the hinge point with the first frame body 11 as the center. During the adjustment process, the threaded sleeve 4 will move linearly in the strip-shaped groove 13, so that the first frame body 11 and the second frame body 12 connected in a V shape expand and support the belt or chain.

[0030] In one embodiment, the number of the limiting devices 8 is multiple and they are arranged at both ends of the guiding groove 5. The limiting device 8 includes a housing 81 installed at the straight end of the second frame body 12, a blocking pin 82 with one end slidably inserted into the housing 81, a spring 83 arranged in the housing 81, and a pull rod 84 installed at the end of the blocking pin 82 close to the spring 83 and extending outside the housing 81. The housing 81 is installed on the side wall of the second frame body 12 and corresponds to the guiding groove 5. One end of the spring 83 is connected to the housing 81, and the other end is connected to the blocking pin 82. The blocking pin 82 is a wedge-shaped pin body and is inserted into the guiding groove 5, and the inclined side of the blocking pin 82 faces the middle of the guiding groove 5.

[0031] In specific implementation, the staff pushes the installation rod 6 to move it to the corresponding position in the guiding groove 5. When it passes through the limiting device 8, it first contacts the inclined side of the blocking pin 82. As the installation rod 6 continues to move, it will squeeze the blocking pin 82 into the interior of the housing 81, so that the blocking pin 82 can move to the flat side of the blocking pin 82. After the movement is completed, the blocking pin 82 is pushed by the spring 83 and reinserted into the guiding groove 5. At this time, the installation rod 6 contacts the flat side of the blocking pin 82, so that the installation rod 6 can be locked and limited.

[0032] In one embodiment, a locking groove 85 with an arc-shaped outer shape is provided on the flat side of the blocking pin 82, and the locking groove 85 cooperates with the installation rod 6.

[0033] With such a design, when the installation rod 6 contacts the flat side of the blocking pin 82, the installation rod 6 is located in the locking groove 85, which further improves the limiting stability of the installation rod 6 and can prevent the belt or chain from shaking when contacting the pulley set 7 and affecting the smooth operation.

[0034] In one embodiment, a linkage handle 9 is installed at one end of each pull rod 84 located outside the shell 81. The staff holds the linkage handle 9 and pulls it, which can drive the pull rods 84 to move synchronously. During specific use, the staff's hand can pass through the expanded first frame 11 and the second frame 12 and contact the linkage handle 9 to operate, thereby making the adjustment process very unified and convenient.

[0035] In one embodiment, an anti-scratch layer is installed on the pulley block 7. The anti-scratch layer may be a silicone layer. The anti-scratch layer is used to prevent the pulley block 7, belts and chains from being scratched, so as to enhance the safety of their operation.
