[0001] This utility model relates to the field of yarn rack technology for woven bags, and in particular to a yarn rack for woven bag production. Background Technology
[0002] In modern industrial and agricultural production, woven bags have become an important choice for product packaging due to their advantages of low cost, high strength and good moisture resistance. They are mainly used in the packaging of various products such as cement, fertilizer and grain.
[0003] In the woven bag production process, yarn racks are key equipment used to hold, place, and continuously and stably supply yarn rolls to the weaving machines. Currently, the structural design of some yarn racks is relatively fixed, making it difficult to flexibly adjust according to different production needs and workshop layouts. This results in inefficient space utilization. Existing solutions involve laying tracks on the workshop floor, with the yarn rack moving along the tracks via sliders or rollers. This makes the movement of the yarn rack more stable and precise, suitable for situations requiring frequent movement of the yarn rack within a specific area. However, it is difficult to flexibly adjust the space of the yarn rack according to the number and size of the yarn rolls, resulting in inflexible space utilization. When the number of yarn rolls is small, the yarn rack cannot be retracted to reduce the floor space occupied, leading to wasted workshop space and failing to meet the needs of different work scenarios.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a yarn frame for woven bag production, comprising multiple fixed frames 1. Connecting plates 3 are fixedly connected to adjacent sides of the left fixed frame 1, serving to connect the fixed frames 1. Fixed shafts 4 are rotatably connected to the inner walls of the multiple connecting plates 3, allowing the connecting plates 3 to rotate freely on the outer walls of the fixed shafts 4. Rotating shafts 5 are rotatably connected to the bottom of each of the left fixed frames 1, with fixed posts 6 fixedly connected to the bottom ends of both rotating shafts 5. The fixed posts 6 rotate with the rotation of the rotating shafts 5. Moving wheels 7 are fixedly connected to adjacent sides of the bottom of the right fixed frame 1, providing convenient movement for the entire yarn frame. Locking rods 8 are slidably connected to opposite sides of the bottom of the right fixed frame 1, with the bottom adjacent sides of the two locking rods 8 engaging with the outer walls of the two moving wheels 7 respectively. When the yarn frame moves to a designated position, sliding the locking rods 8 engages their bottoms with the outer walls of the moving wheels 7, thus restricting the rotation of the moving wheels 7. Each of the multiple fixed frames 1 has a sliding groove 9 on an adjacent side. A connecting frame 2 10 is provided between the adjacent sliding grooves 9. A slider 11 is fixedly connected to the left and right sides of the outer wall of the multiple connecting frame 2 10. The outer wall of the multiple slider 11 is slidably connected to the inner wall of the multiple sliding grooves 9. The connecting frame 2 10 realizes the sliding function between the fixed frames 1 through the cooperation of the slider 11 with the sliding grooves 9 on the fixed frame 1. A limiting hole 12 is fixedly connected to an adjacent side of the multiple connecting frame 2 10. A placement bucket 13 is provided on the right side of the outer wall of the multiple limiting hole 12. The opposite side of the multiple placement buckets 13 is fixedly connected to the adjacent side of the multiple connecting frame 2 10. The limiting hole 12 is used to position and fix the placement bucket 13 to a certain extent. The placement bucket 13 is used to place some auxiliary items related to yarn processing. An adjustment mechanism 2 is provided at the bottom of the outer wall of the left fixed frame 1. The adjustment mechanism 2 is used to adjust the height of the connecting frame 2 10.
[0032] Specifically, multiple fixed frames 1 constitute the main frame. The left fixed frame 1 is connected by a connecting plate 3. The fixed shaft 4, which is rotatably connected to the inner wall of the connecting plate 3, allows the fixed frame 1 to rotate smoothly. The rotating shaft 5 and the bottom fixed column 6, which are rotatably connected to the bottom of the left fixed frame 1, cooperate with the moving wheel 7 at the bottom of the right fixed frame 1 to realize the flexible movement of the yarn frame. The rotating shaft 5 allows the fixed column 6 to turn flexibly, and the moving wheel 7 facilitates the overall displacement. The locking rod 8 at the bottom of the right fixed frame 1 slides and engages with the outer wall of the moving wheel 7 to fix the position of the yarn frame and prevent it from shifting during operation. The sliding groove 9 on the adjacent side of the fixed frame 1 is slidably connected to the slider 11 on the outer wall of the connecting frame 2 10, which facilitates the adjustment of the spacing of the connecting frame 2 10 to adapt to the placement needs of different yarn rolls. The limiting hole 12 on one side of the connecting frame 2 10 can fix the placement bucket 13. The placement bucket 13 can store yarn processing auxiliary items for easy operation.
[0033] Reference Figure 1 , Figure 2 and Figure 5The adjusting mechanism 2 includes two connecting frames 201, which are fixedly connected to the left side of the outer wall of the left slider 11. Since the slider 11 is slidably connected to the slide groove 9 on the fixed frame 1, this fixed connection allows the connecting frame 201 to move as the slider 11 slides within the slide groove 9. Support columns 202 are fixedly connected to the bottom of each connecting frame 201. The sliding of the support columns 202 at the bottom of the left fixed frame 1 provides vertical position adjustment for the connecting frame 201. The two support columns 202 are slidably connected to the bottom of the left fixed frame 1. Multiple connecting blocks 203 are fixedly connected to the bottom of the outer wall of the fixed frame 1. Springs 204 are fixedly connected to the inner walls of the multiple connecting blocks 203. The connecting blocks 203 provide installation positions for the springs 204 and the limiting posts 205. The limiting posts 205 are slidably connected to the inner walls of the multiple connecting blocks 203. The outer walls of the multiple limiting posts 205 are fixedly connected to the outer walls of the multiple springs 204 respectively. Multiple locking blocks 206 are fixedly connected to the bottom of the left fixed frame 1 on the adjacent side. The inner walls of the multiple locking blocks 206 are locked to the outer walls of the multiple limiting posts 205 respectively. The locking relationship between the locking blocks 206 and the limiting posts 205 is the key to the position locking of the adjustment mechanism 2.
[0034] Specifically, two connecting frames 201 are fixed to the left side of the outer wall of the left slider 11. Since the slider 11 can slide within the groove 9, the connecting frame 201 can move with the slider 11 and coordinate with other parts of the yarn frame. The support column 202 at the bottom of the connecting frame 201 is slidably connected to the bottom of the left fixed frame 1, allowing for fine-tuning of the vertical position to adapt to different yarn roll heights or other production needs. The connecting block 203 at the bottom of the outer wall of the left fixed frame 1 provides an installation base for the spring 204 and the limiting column 205. The spring 204 is fixed to the inner wall of the connecting block 203 and connected to the limiting column 205. When the support column 202 slides, the spring 204 can buffer the impact force to avoid damage to the equipment. At the same time, it provides a reverse elastic force after adjustment to help the limit column 205 stabilize its position. The locking block 206 on the adjacent side of the bottom of the left fixed frame 1 engages with the outer wall of the limit column 205. When the support column 202 drives the connecting frame 1 201 to move to the appropriate position, the limit column 205 is tightly engaged with the locking block 206 under the action of the spring 204 to prevent the support column 202 from sliding at will. This ensures that the state of the adjustment mechanism 2 is stable after adjustment, thereby ensuring the stability of the position of the relevant parts on the yarn frame and meeting the requirements of yarn frame structure stability for woven bag production.
[0035] Reference Figure 1 , Figure 2 and Figure 3Each of the two connecting frames 10 has an installation groove 14 on its outer wall, and a reflective sticker 15 is provided on the inner wall of each installation groove 14. The installation groove 14 provides a dedicated installation position for the reflective sticker 15, ensuring that the reflective sticker 15 can be stably fixed on the connecting frame 10. The bottom of each of the two fixing posts 6 is fixedly connected with a foot pad 16. The two foot pads 16 have a smooth design, which plays a role in protecting the ground and enhancing stability. Each of the two locking rods 8 has an installation groove 17 on its outer wall, and a handle 18 is fixedly connected to the inner wall of each of the two installation grooves 17. The handle 18 is designed to facilitate the operation of the locking rod 8 by the operator.
[0036] Specifically, mounting groove 14 provides a stable mounting position for reflective sticker 15, ensuring that it will not easily fall off. Reflective sticker 15 can reflect light under illumination, enhancing the visibility of the yarn frame. Foot pad 16 can reduce the direct friction and damage between the fixing post 6 and the ground, which is especially suitable for workshops with high requirements for the ground. The smooth design makes the yarn frame more stable during movement and disperses the pressure when the fixing post 6 contacts the ground. Mounting groove 2 17 ensures a firm connection between handle 18 and locking rod 8.
[0037] Reference Figure 2 , Figure 4 and Figure 5 The bottom right side of the right-side fixing frame 1 is provided with mounting groove 3 19. The inner walls of the two mounting groove 3 19 are fixedly connected to the indicator arrows 20. The mounting groove 3 19 provides a precise and stable installation position for the indicator arrows 20, ensuring that the indicator arrows 20 can reliably function on the right-side fixing frame 1. The top of the outer wall of the right-side fixing frame 1 is provided with connecting groove 1 21. The inner walls of the two connecting groove 1 21 are fixedly connected to the warning signs 22, which alert the staff to pay attention to safety. The middle right side of the right-side fixing frame 1 is provided with connecting groove 23. The inner walls of the two connecting groove 23 are fixedly connected to the handle 24, which allows the operator to better control the force and direction when pushing or pulling the yarn frame.
[0038] Specifically, the mounting slot 3 19 is precisely sized to match the indicator arrow 20, ensuring a secure installation. The connecting slot 1 21 ensures the stability of the warning sign 22 installation. The warning sign 22 usually has prominent warning information printed on it. The connecting slot 23 securely connects the handle 24 to the mounting bracket 1. When the mounting bracket 1 needs to be opened, the operator holds the handle 24 and applies appropriate force to push or pull the mounting bracket 1.
[0039] Working principle: When the yarn rack for woven bag production is in operation, when the worker needs to open the fixed frame 1, he pushes the right fixed frame 1, and the left fixed frame 1 rotates on the fixed shaft 4 through the connecting plate 3. At the same time, the left bottom rotating shaft 5 also rotates, realizing the opening operation of the fixed frame 1. The rotating shaft 5 at the bottom of the left fixed frame 1 is connected to the fixed column 6. The bottom of the right fixed frame 1 has a moving wheel 7, which facilitates the overall movement of the yarn rack. The sliding locking rod 8 engages with the outer wall of the moving wheel 7, which can fix the yarn rack in the required position. The sliding groove 9 opened on the adjacent side of the fixed frame 1 cooperates with the slider 11 on the outer wall of the connecting frame 2 10, which allows the connecting frame 2 10 to slide and adjust its position flexibly according to the requirements. The limiting hole 12 on one side of the connecting frame 2 10 can fix the placement bucket 13. The placement bucket 13 can store auxiliary items related to yarn processing.
[0040] Furthermore, when adjustment is required, since the connecting frame 201 is fixed to the left side of the outer wall of the left slider 11, the sliding of the slider 11 will drive the connecting frame 201 to move. The support column 202 at the bottom of the connecting frame 201 can slide at the bottom of the left fixed frame 1 to achieve fine adjustment of the vertical position. During the adjustment process, the spring 204 in the connecting block 203 at the bottom of the outer wall of the left fixed frame 1 will expand and contract according to the force transmitted by the support column 202, which plays a buffering role and avoids hard collision damage to the parts. At the same time, the spring 204 can also provide a reverse elastic force to the limiting column 205 connected to it. When the support column 202 drives the connecting frame 201 to the appropriate position, the limiting column 205 is tightly engaged with the locking block 206 on the adjacent side of the bottom of the left fixed frame 1 under the action of the spring 204, preventing the support column 202 from sliding at will, thereby stabilizing the adjusted state and ensuring that the relevant parts on the yarn frame are accurately and stably positioned to meet the different needs of woven bag production.
