Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, specifically an automatic strapping machine feeding device. Background Technology

[0002] Pallet strapping machines are essential equipment in modern logistics and warehousing for securing palletized goods. They automatically pass straps through the bottom of the pallet and tighten them, replacing the traditional, arduous manual strapping process, significantly improving packing efficiency and reducing labor intensity.

[0003] In existing technologies, such equipment typically uses chain drag chains or similar transmission mechanisms to pull the strapping to complete the strapping action. The operator only needs to fix the initial end of the strapping to the packaging machine, and the equipment can automatically complete a series of subsequent processes such as strapping, tightening, welding and cutting.

[0004] However, the material tray of existing strapping machines is usually rotatably mounted on one side of the frame via a simple rotating shaft structure. When the strapping is dragged, the material tray rotates to release the material. However, because the material tray (especially when fully loaded with wide and heavy rolls) has a large moment of inertia, it continues to rotate under inertia after the dragging stops, causing the strapping to become excessively loose and spread out haphazardly. To prevent this, the operator must manually intervene during each strapping interval to force the material tray to stop rotating. This operation not only increases the workload of the workers and disrupts the continuity of the operation, but also reduces the overall efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an automatic feeding device for a threading machine, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic threading machine feeding device, comprising a threading machine body and a material tray, a fixed frame fixedly connected to one side of the threading machine body, a movable arm rotatably connected to the top of the fixed frame, a hydraulic rod rotatably arranged between the movable arm and the fixed frame, a connecting seat provided on one side of the movable arm, a material tray provided on one side of the connecting seat, a shaft core for cooperating with the material tray provided at the end of the connecting seat, a toothed ring fixedly installed on the outer wall of the material tray, teeth arranged around the inner wall of the toothed ring, and a limit component installed on the outer side of the connecting seat.

[0007] As a further embodiment of this utility model: the limiting component includes a limiting rod and a connecting rod, one end of the connecting rod is fixed to the connecting seat, the other end of the connecting rod is hinged to the middle of the limiting rod, one end of the limiting rod is provided with a hook structure and engages with the teeth, and the other end of the limiting rod is connected to a spring.

[0008] As a further embodiment of this utility model: a fixing pin is inserted into the connecting seat, the shaft section of the fixing pin is fixedly connected to the movable arm, and the other end of the spring is fixedly connected to the end of the fixing pin.

[0009] As a further embodiment of this utility model: the toothed ring is circular, and the inclination of the teeth is consistent with the clockwise rotation direction of the material tray.

[0010] As a further embodiment of this utility model: a shaft hole is provided in the material tray, a bearing is fixedly installed on the inner wall of the shaft hole, the inner wall of the bearing is sleeved on the outer side of the shaft core, and a retaining ring is connected to the end of the shaft core.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Automatic braking and easy operation: This utility model sets up a toothed ring and a limiting component. When the material tray is dragged and rotates clockwise, the hook of the limiting rod is engaged in the groove between the teeth under the spring tension, generating resistance to achieve automatic braking. This effectively suppresses the excessive rotation of the material tray due to inertia, without the need for manual intervention, thus improving the convenience and safety of operation.

[0013] 2. Strong adaptability and stable reliability: The hydraulic rod is used to drive the movable arm to swing around the hinge point, thereby precisely adjusting the angle and position of the material tray. This allows the device to be used to install packing tape rolls of different widths. At the same time, the rigid support characteristics of the hydraulic rod itself can provide a stable support force for the movable arm and the material tray, ensuring that the material tray can be stably fixed in the required position when working and stationary, effectively preventing tipping, and greatly improving the flexibility and reliability of the equipment.

[0014] 3. Simple structure and easy maintenance: The limiting component and material tray of this utility model have a simple installation structure, low manufacturing cost, and are easy to disassemble, maintain and replace. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-7 As shown, this utility model provides a technical solution:

[0025] An automatic tape threading machine feeding device includes a tape threading machine body 1 and a material tray 2. A fixed frame 3 is fixedly connected to one side of the tape threading machine body 1. A movable arm 4 is rotatably connected to the top of the fixed frame 3. A hydraulic rod 5 is rotatably arranged between the movable arm 4 and the fixed frame 3. A connecting seat 6 is provided on one side of the movable arm 4. The material tray 2 is provided on one side of the connecting seat 6. A shaft core 7 for cooperating with the material tray 2 is provided at the end of the connecting seat 6. A toothed ring 8 is fixedly installed on the outer wall of the material tray 2. Teeth 9 are arranged around the inner wall of the toothed ring 8. A limit component 10 is installed on the outer side of the connecting seat 6.

[0026] Specifically, the strip material to be conveyed is neatly wound onto the tray 2, and the tray 2 is precisely installed and fixed by the shaft core 7 at the end of the connecting seat 6, ensuring that the toothed ring 8 on the outer wall of the tray 2 corresponds to the position of the limiting component 10 on the outer side of the connecting seat 6. Then, the connection stability between the fixed frame 3 and the movable arm 4 is checked, and the angle of the movable arm 4 is adjusted to a position suitable for the feeding requirements by the hydraulic rod 5, thus completing the preparation work before starting the equipment.

[0027] After the automatic tape threading machine is started, the main body 1 of the tape threading machine pulls the tape to move. The tape drives the material tray 2 to rotate clockwise for feeding. During this process, when the material tray 2 rotates under the drag force, the hook of the limit rod 11 in the limit component 10 automatically engages with the groove between the teeth 9 on the inner wall of the toothed ring 8 under the pull of the spring 13, generating stable resistance to achieve automatic braking, effectively suppressing the excessive rotation of the material tray 2 due to inertia. After the tape is conveyed to the designated position, the equipment stops running and completes a single feeding operation.

[0028] Through the cooperation of the toothed ring 8 and the limiting component 10, the automatic braking of the material tray 2 can be achieved without manual intervention. This avoids problems such as strip entanglement and disorder caused by excessive rotation of the material tray 2, ensuring the stability and accuracy of the feeding process. It also reduces the workload of manual monitoring and intervention, lowers the difficulty of operation, and avoids the safety hazards that may be caused by manual contact with moving parts. This significantly improves the convenience and safety of operation and optimizes the operating efficiency and user experience of the automatic threading machine.

[0029] The limiting assembly 10 includes a limiting rod 11 and a connecting rod 12. One end of the connecting rod 12 is fixed to the connecting seat 6, and the other end of the connecting rod 12 is hinged to the middle of the limiting rod 11. One end of the limiting rod 11 is provided with a hook structure and engages with the tooth 9. The other end of the limiting rod 11 is connected to a spring 13. A fixing pin 14 is inserted into the connecting seat 6. The shaft section of the fixing pin 14 is fixedly connected to the movable arm 4. The other end of the spring 13 is fixedly connected to the end of the fixing pin 14. The tooth ring 8 is circular, and the inclination of the tooth 9 is consistent with the clockwise rotation direction of the material tray 2. A shaft hole 15 is opened in the material tray 2. A bearing 16 is fixedly installed on the inner wall of the shaft hole 15. The inner wall of the bearing 16 is sleeved on the outside of the shaft core 7. A retaining ring 17 is connected to the end of the shaft core 7.

[0030] Specifically, in use, the material tray 2 is first sleeved on the shaft core 7 at the end of the connecting seat 6 through the bearing 16 in the shaft hole 15, and fixed by the retaining ring 17 to prevent the material tray 2 from falling off axially. This ensures that the toothed ring 8 on the outer wall of the material tray 2 is engaged with the hook structure of the limiting rod 11 in the limiting assembly 10. At the same time, the limiting rod 11 is hinged to the connecting rod 12 in the middle to achieve flexible rotation. The spring 13 connected to its other end is fixed to the end of the fixing pin 14 on the connecting seat 6 to form a stable elastic limiting structure.

[0031] Based on the width of the packing tape roll to be conveyed, the hydraulic rod 5 between the fixed frame 3 and the movable arm 4 is controlled to drive the movable arm 4 to swing around the hinge point, precisely adjusting the angle and position of the tray 2 to match the width of the roll. After the adjustment is completed, the hydraulic rod 5 provides stable support for the movable arm 4 and the tray 2 by virtue of its rigid support characteristics.

[0032] After the equipment is started, the strip drag tray 2 rotates clockwise. Since the tilt direction of the teeth 9 is consistent with the clockwise rotation direction of the tray 2, the hook of the limit rod 11 is lifted with the rotation, which does not affect the feeding. When the dragging force decreases or stops, the spring 13 pulls the limit rod 11 to reset, and the hook engages between the teeth 9 to achieve braking and prevent the tray 2 from rotating due to inertia.

[0033] The working principle of this utility model is as follows:

[0034] First, the conveying strip is wound onto the material tray 2. The material tray 2 is fitted onto the shaft core 7 of the connecting seat 6 through the bearing 16 in the shaft hole 15 and fixed by the retaining ring 17 to ensure that the toothed ring 8 and the hook of the limiting rod 11 of the limiting component 10 are engaged. The limiting rod 11 is hinged to the connecting seat 6 via the connecting rod 12, and the other end is connected to the fixing pin 14 via the spring 13 to form an elastic limiting structure. At the same time, the angle of the movable arm 4 is adjusted by the hydraulic rod 5 to adapt to the width of the material roll.

[0035] Secondly, after the equipment is started, the main body 1 of the threading machine pulls the belt and drives the material tray 2 to rotate clockwise. Since the tilt direction of the teeth 9 is consistent with the rotation direction, the hook of the limit rod 11 is lifted with the rotation, which does not obstruct the feeding. When the dragging force decreases or stops, the spring 13 pulls the limit rod 11 to reset, and the hook is engaged between the teeth 9 to generate resistance, thereby achieving automatic braking and suppressing the excessive rotation of the material tray 2 due to inertia.

[0036] It is worth mentioning that the hydraulic rod 5 drives the movable arm 4 to swing around the hinge point, precisely adjusting the angle and position of the material tray 2 to adapt to packing tape rolls of different widths, improving the flexibility of the equipment. At the same time, thanks to its own rigid support characteristics, it provides stable support for the movable arm 4 and the material tray 2, ensuring that they can be stably fixed when working and stationary, preventing tipping and ensuring work reliability.

[0037] Finally, automatic braking is achieved through the cooperation of the toothed ring 8 and the limiting component 10, without the need for manual intervention, avoiding strip entanglement and disorder, reducing manual workload and safety hazards. At the same time, the installation structure of the limiting component 10 and the material tray 2 is simple, consisting of basic components such as the limiting rod 11, spring 13, and bearing 16, which is easy to disassemble, maintain and replace, reducing the cost of use.

[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
