Technical Field
[0001] This utility model belongs to the field of yarn packaging, specifically relating to a device for preventing yarn from falling off a packaging machine. Background Technology
[0002] A yarn baling machine is a device specifically designed for packaging wound materials such as yarn, thread, and fabric. It is commonly used in the textile industry and other industries that require neat packaging of thread or yarn. By tightly binding or winding the yarn into packages, the yarn baling machine makes the products easy to transport and store, and ensures that the products will not become loose or damaged during transportation.
[0003] With the increasing automation of spinning mills, automatic yarn baling machines have been widely used. In actual production, during the operation of the automatic yarn baling machine, the yarn bobbins are bagged by the automatic bagging device, arranged neatly, and then pushed into the woven bag by the yarn pushing device. However, during the pushing process, due to the pushing force, occasionally individual yarn bobbins will fall off along the edge. Moreover, the positions of the yarn bobbins pushed into the baling machine by the existing baling machine are often unevenly distributed. As they slide down the baling platform, they tend to move towards the edge, thus affecting the baling effect and efficiency of the baling machine in bagging the yarn bobbins.
[0004] Therefore, to address the problem that some yarn tubes near the edge of the existing yarn tube baling machine tend to fall off during use, and that the neatness of the yarn tubes during baling is poor, which easily affects the packaging effect and efficiency, a device to prevent yarn from falling off the baling machine has been developed. By adding an electric lifting structure, a yarn tube center limiting structure, and an edge baffle structure to the yarn tube baling machine, the probability of yarn tubes falling off along the edge during use can be reduced, the situation of missing packages can be reduced, and the effect and efficiency of the baling machine in baling yarn tubes can be improved. Utility Model Content
[0005] To overcome the problems of existing yarn tube baling machines, such as some yarn tubes near the edge of the baling machine easily falling off and poor neatness of the yarn tubes during baling, which easily affects the packaging effect and efficiency.

Detailed Implementation
[0024] The anti-drop device on a baling machine is designed to ensure that yarn, strapping, or other packaging materials do not fall off due to loosening or instability during the baling process, thus affecting production efficiency or product quality. Below are some common anti-drop device design schemes:
[0025] 1. Tension Control System
[0026] During operation, the yarn or strip of a baling machine may fall off due to unstable tension. By installing a tension control device, the tension of the yarn or strip can be monitored and adjusted in real time to ensure that the appropriate tension is maintained at all times during the baling process, preventing it from loosening and falling off.
[0027] Working principle: The tension of the yarn or strip is monitored in real time by a tension sensor. If the tension is too loose or too tight, the tension adjustment device (such as an electric motor or pneumatic system) will be automatically adjusted.
[0028] Advantages: Provides high-precision tension adjustment, ensures a stable supply of materials, and reduces the risk of falling.
[0029] 2. Automatic yarn guiding device
[0030] Automatic yarn guiding devices ensure that yarns or strips maintain the correct path during transport, preventing them from falling due to deviation from the track or slippage. They guide the yarn to the target area via mechanical guide wheels or motorized guide rails.
[0031] Working principle: The guiding device uses pulleys, guide rails or electric guiding devices to precisely control the movement path of the yarn and prevent it from deviating.
[0032] Advantages: It can improve the stability of the yarn and prevent the yarn from falling off during high-speed operation.
[0033] 3. Clamping device
[0034] Clamping devices are used to firmly hold yarns or strips to prevent them from loosening or falling off during the operation of the packing machine. Clamping devices are typically composed of pneumatic or mechanical components that provide sufficient pressure to ensure the material does not fall. Working principle: Using air pressure, springs, or mechanical devices to clamp the yarn or strip, ensuring it does not loosen during transport.
[0035] Advantages: Simple design, easy to maintain, and effectively prevents materials from falling off.
[0036] 4. Protective netting or protective cover
[0037] Protective nets or covers are installed around the conveying path of yarn or strip so that when the material deviates or falls off during operation, it can be intercepted by the protective nets or covers to prevent it from falling outside the production line.
[0038] Working principle: A protective net or cover is set up on the yarn conveying path of the baling machine. Any loose material will be intercepted inside the equipment to prevent it from falling.
[0039] Advantages: Provides a physical barrier, protects the production environment, and reduces material waste.
[0040] 5. Sensors and Alarm Systems
[0041] Sensors are used to detect whether materials are being supplied correctly, and an alarm system is in place to immediately sound an alarm if any material is detected falling or shifting. This allows operators to identify and correct problems promptly, preventing further material drops from impacting production.
[0042] Working principle: Sensors, such as photoelectric sensors or pressure sensors, are installed at key locations to monitor the material's status in real time. When material is detected falling or shifting in position, the sensor triggers an alarm to alert the operator.
[0043] Advantages: Improves the intelligence level of the production line and enables rapid response to abnormal situations.
[0044] 6. Static electricity anti-fall system
[0045] Some yarn materials may generate static electricity due to their different properties, causing the yarn to stick to the equipment and then fall off. Static electricity prevention systems eliminate static electricity, maintaining the stability of the yarn.
[0046] Working principle: By installing an electrostatic eliminator, the static charge on the surface of the yarn is eliminated, thereby preventing the yarn from sticking or slipping and maintaining a stable supply.
[0047] Advantages: It is very effective for materials that are prone to static electricity, and can reduce the problem of wires falling off due to static electricity.
[0048] 7. Airflow-assisted delivery system
[0049] Airflow is used to assist in the conveying of yarn or strip material, and the material is stably fed into the packing machine through uniform airflow. The airflow can provide a certain support force to prevent the yarn from falling off during the conveying process.
[0050] Working principle: An airflow device is installed on the yarn or strip conveying path. By adjusting the size and direction of the airflow, the material is ensured to pass through stably.
[0051] Advantages: Airflow can effectively reduce material friction and the risk of falling, making it suitable for certain materials that are easily affected by external interference.
[0052] Summarize:
[0053] The design of anti-drop devices should be selected based on the specific type of packing machine, packing materials, and production environment. Multiple methods can usually be combined to achieve a more efficient and stable anti-drop effect, ensuring a stable material supply during production, reducing waste, and improving production efficiency.

The electric telescopic rod 5 can drive the two sets of lifting plates 3 to move upward along the inner wall of the first groove 7, thereby flexibly adjusting the anti-fall range of the lifting plates 3 according to the need to prevent yarn packages of different sizes from falling off during bagging. The two sets of bagging paddles 4, which are distributed at an angle, can provide limiting assistance for the yarn packages pushed into the bagging box 1, so that they slide to the center of the packaging bag. The spring 18 can be adjusted up and down with the lifting plates 3 to adapt to the needs of bagging yarn packages of different sizes.
[0056] Please see Figures 3-4 In this embodiment, support feet 8 are fixedly connected to the four corners of the lower end of the bagging box 1, a yarn pushing plate 9 is fixedly connected to the front end of the bagging box 1, and a bagging frame 2 is fixedly connected to the rear end of the bagging box 1.

A first groove 7 is symmetrically distributed on the upper edge of the bagging box 1, and equal-distance limiting grooves 6 are opened through the left and right ends of the bagging box 1. The limiting grooves 6 are connected to the first grooves 7. During use, the first grooves 7 can provide preliminary limiting assistance for the vertical displacement adjustment of the lifting plate 3 to improve its stability during lifting adjustment.
[0057] Please see Figure 5In this embodiment, equidistant limiting posts 11 are fixedly connected to the edges of the lifting plate 3 at their far-away ends, and a fixing plate 12 is fixedly connected to the far-away ends of the limiting posts 11. In use, the limiting frame structure formed by the limiting posts 11 and the fixing plate 12 can further improve the stability of the lifting plate 3 in adjusting its height along the inner wall of the first groove 7. The outer wall of the lifting plate 3 is in contact with the inner wall of the first groove 7, and the lower ends of the rear limiting plate 13 and the bagging lever 4 are in contact with the upper end of the bagging box 1. In use, the rear limiting plate 13 and the bagging lever 4 can assist the yarn bobbin when it enters the bagging box 1 and when the yarn is bagged, respectively, to improve the effect and efficiency of bagging.
[0058] Please see Figures 3-6 In this embodiment, a second groove 10 is symmetrically distributed at the lower inner wall of the first groove 7. The electric telescopic rod 5 is installed in the second groove 10. In use, the electric telescopic rod 5 can drive the lifting plate 3 to be raised and lowered along the inner wall of the first groove 7. The limiting groove 6 is adapted to the limiting post 11. The ends of the fixing plate 12 that are close to each other are attached to the left and right ends of the bag box 1.

The automatic bagging device automatically puts the packaging bag on the bagging frame 2, and the generated yarn bobbin is transported to the yarn pushing plate 9 by the conveyor belt. The yarn pushing device pushes the yarn bobbin into the bagging box 1.
[0060] Next, the yarn bobbins pushed into the bagging box 1 are limited and moved by two sets of angled bagging paddles 4, so that they are as close as possible to the center of the inner wall of the bagging box 1. The lifting plate 3 driven by the electric telescopic rod 5 extends upward along the inner wall of the first groove 7, so that the plastic plate 15 and the rear limiting plate 13 on it are located at the left and right edges of the bagging box 1, thereby limiting and blocking the yarn bobbins entering the bagging box 1 to prevent individual yarn bobbins from falling off the edge of the bagging box 1.
[0061] Through the above steps, the limiting structure consisting of plastic plates 15 and rear limiting plates 13 on the two sets of lifting plates 3 provides multi-directional limiting and blocking for the left and right ends of the bagging box 1, preventing individual yarn bobbins from falling off the edge of the bagging box 1 during bagging. The electric telescopic rod 5 can drive the two sets of lifting plates 3 to move upward along the inner wall of the first groove 7, thereby flexibly adjusting the anti-fall range of the lifting plates 3 according to the need to prevent yarn bobbins of different sizes from falling off during bagging. In addition, the two sets of bagging paddles 4 distributed at an angle can provide limiting assistance for the yarn bobbins pushed into the bagging box 1, so that they slide to the center of the packaging bag.
