Description

Technical Field

[0001] This utility model relates to the field of packing machine technology, and in particular to a fully automatic pure electric packing machine core. Background Technology

[0002] The strapping mechanism is the key component in a strapping machine responsible for realizing the core strapping function. It mainly relies on pneumatic components such as cylinders, solenoid valves, and pneumatic motors to provide driving force, driving the whole machine to complete key operations such as tightening the strapping tape, welding the interface, and cutting off the excess material during the strapping process. It is the core component that ensures that the strapping machine can stably and efficiently realize the function of bundling items.

[0003] Existing baling machine mechanisms generally use cylinders, solenoid valves, and pneumatic motors to drive the entire machine. Cylinders have specific requirements for air pressure, solenoid valves have extremely high requirements for air purity, and pneumatic motors have extremely high air pressure requirements. Baling machine mechanisms that extensively use pneumatic components require users to equip themselves with auxiliary equipment such as air compressors, dryers, and air-water separators. The influence of air pressure on cylinders can cause unpredictable effects on the speed of operation and downforce, leading to frequent malfunctions. Furthermore, regional climate differences can result in varying air pressures even under the same conditions. Equipment using pneumatic components also requires air pipes and connections, which are also... Pneumatic strapping machines suffer from several drawbacks. Components are susceptible to rapid aging due to weather conditions. They also suffer from poor stability, large size, and numerous inter-component connections. Operators need a basic understanding of pneumatic components, and troubleshooting is difficult. Furthermore, existing strapping mechanisms suffer from low energy efficiency (requiring continuous power from an air compressor, resulting in high energy consumption), noise pollution (pneumatic component operating noise ≥85dB), complex maintenance (air pipes / oil lines are prone to leaks, requiring regular seal replacement), and poor control precision (fluctuations in air / hydraulic pressure lead to unstable belt tension). Therefore, this invention proposes a fully automatic, pure electric strapping mechanism to address these problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a fully automatic pure electric packing mechanism. This fully automatic pure electric packing mechanism adopts a modular design, which facilitates daily maintenance and reduces the difficulty of repair.

[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0023] Example 1

[0024] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a fully automatic pure electric packing mechanism, including a frame 1 and a welding mechanism 3.

A pressing wheel 7 is provided on the outer side of the feeding wheel 8. An operation switch 2 is provided on the frame 1 for manual operation.

[0025] The welding mechanism 3 includes a body, a camshaft 9, and a dynamic and static welding module. The camshaft 9 is rotatably located at the top of the body, and a cam assembly 10 is provided on the outer side of the camshaft 9. The dynamic and static welding module is located at the bottom of the body and is adapted to the cam assembly 10. The dynamic and static welding module includes a first dynamic and static welding module 11, a second dynamic and static welding module 12, and a third dynamic and static welding module 13. Conventional packaged goods include an electric strapping mechanism, a frame, a four-sided grooved assembly, and a strapping tape delivery trolley. The strapping mechanism performs operations such as tightening, welding, and cutting of the strapping tape to achieve the packaging of goods. The frame, the four-sided grooved assembly, and the strapping tape delivery trolley in the whole machine are not described here. The strapping mechanism is as follows... Figure 1 The process is divided into two parts: belt feeding and welding. After the strapping tape enters the belt feeding roller 8, it moves forward along the channel, completes a full circle in the 4-circle belt groove, and then returns to the strapping core to touch the belt switch 27, completing the belt feeding. At this time, the pressure roller 7 performs a belt tightening action. After the strapping tape is tightened, the welding mechanism 3 performs a cutting welding action. Specifically, the belt feeding roller 8 rotates forward to feed the tape. After reaching the belt switch 27, the cam group 10 rotates an angle so that its first cam presses against the dynamic and static welding module 11. At this time, the upper belt is pressed down and the first angle signal of the cam group 10 is obtained. The pressure roller 7 tightens the tape to the required level. Once the set torque is reached, feedback is sent to the cam drive motor 14. Upon receiving the signal, the cam group 10 rotates another angle, and the fourth cam presses down onto the dynamic-static welding module three 13. At the same time, the second cam of the cam group 10 presses down on the dynamic-static welding module two 12. The dynamic-static welding module three 13 presses down on the lower layer of tape, and the dynamic-static welding module two 12 cuts and presses down on the upper and lower layers of packaging bags. The reciprocating welding motor 15 starts and moves back and forth with the lower friction plate 22 of the dynamic-static welding module two 12 through the connector 16, causing the upper and lower layers of tape to rub and heat up, eventually welding them together.

[0026] A cam drive motor 14 is located above one end of the machine body, and the output end of the cam drive motor 14 is connected to a camshaft 9. The cam assembly 10 has four cams, and the cam drive motor 14 drives the camshaft 9 and the cams to rotate. A reciprocating welding motor 15 is located below one end of the machine body, and the output end of the reciprocating welding motor 15 is connected to a connector 16. A lower friction plate 22 is located below the dynamic and static welding module, and the reciprocating welding motor 15 reciprocates with the lower friction plate 22 through the connector 16. The belt is fed by the forward rotation of the feed roller 8. After reaching the belt switch 27, the cam group 10 rotates by an angle so that its first cam presses against the dynamic and static welding module 11. At this time, the upper belt is pressed down and the first angle signal of the cam group 10 is obtained. The clamping roller 7 is tightened to the set torque and then fed back to the cam drive motor 14. The cam drive motor 14 receives the signal and the cam group 10 rotates by another angle. The fourth cam presses down against the dynamic and static welding module 3 13. At the same time, the second cam of the cam group 10 presses down on the dynamic and static welding module 2 12. The dynamic and static welding module 3 13 presses down on the lower belt. The dynamic and static welding module 2 12 cuts and presses down on the upper and lower packaging bags. The reciprocating welding motor 15 starts and moves back and forth with the lower friction plate 22 of the dynamic and static welding module 2 12 through the connector 16, so that the upper and lower belts rub and heat up and finally fuse together.

[0027] The frame 1 has a tape outlet 17, a connection port 18, and a tape inlet 19 at its lower part, which are connected to the interior of the frame 1. They are used for tape feeding and discharging.

[0028] One side of the machine body is provided with a drive wheel 20 and a connecting wheel. The connecting wheel is connected to the camshaft 9, and the connecting wheel and the drive wheel 20 are connected by a belt 21. The drive wheel 20 is used to connect to the signal disk. In use, the cam drive motor 14 drives the camshaft 9 and the cam to rotate, causing the connecting wheel to rotate. The belt 21 drives the drive wheel 20 to rotate, causing the signal disk to rotate, thus obtaining the angle signal of the cam group 10.

[0029] The outer end of the machine body is provided with a release door plate 23 for opening and maintaining the welding mechanism 3. The inner end of the upper part of the machine body is provided with a belt stop switch 27. In use, the feeding belt and the welding and packing belt enter the feeding roller 8 and move forward along the channel, then complete a full circle in the 4-circle belt groove and return to the packing core to meet the belt stop switch 27 to complete the feeding. At this time, the pressure roller 7 performs the belt tightening action. After the packing belt is tightened, the welding mechanism 3 performs the cutting welding.

[0032] The welding mechanism 3 includes a body, a camshaft 9, and a dynamic and static welding module. The camshaft 9 is rotatably located at the top of the body, and a cam assembly 10 is provided on the outer side of the camshaft 9. The dynamic and static welding module is located at the bottom of the body and is adapted to the cam assembly 10. The dynamic and static welding module includes a first dynamic and static welding module 11, a second dynamic and static welding module 12, and a third dynamic and static welding module 13. Conventional packaged goods include an electric strapping mechanism, a frame, a four-sided grooved assembly, and a strapping tape delivery trolley. The strapping mechanism performs operations such as tightening, welding, and cutting of the strapping tape to achieve the packaging of goods. The frame, the four-sided grooved assembly, and the strapping tape delivery trolley in the whole machine are not described here. The strapping mechanism is as follows... Figure 1 The process is divided into two parts: belt feeding and welding. After the strapping tape enters the belt feeding roller 8, it moves forward along the channel, completes a full circle in the 4-circle belt groove, and then returns to the strapping core to touch the belt switch 27, completing the belt feeding. At this time, the pressure roller 7 performs a belt tightening action. After the strapping tape is tightened, the welding mechanism 3 performs a cutting welding action. Specifically, the belt feeding roller 8 rotates forward to feed the tape. After reaching the belt switch 27, the cam group 10 rotates an angle so that its first cam presses against the dynamic and static welding module 11. At this time, the upper belt is pressed down and the first angle signal of the cam group 10 is obtained. The pressure roller 7 tightens the tape to the required level. Once the set torque is reached, feedback is sent to the cam drive motor 14. Upon receiving the signal, the cam group 10 rotates another angle, and the fourth cam presses down onto the dynamic-static welding module three 13. At the same time, the second cam of the cam group 10 presses down on the dynamic-static welding module two 12. The dynamic-static welding module three 13 presses down on the lower layer of tape, and the dynamic-static welding module two 12 cuts and presses down on the upper and lower layers of packaging bags. The reciprocating welding motor 15 starts and moves back and forth with the lower friction plate 22 of the dynamic-static welding module two 12 through the connector 16, causing the upper and lower layers of tape to rub and heat up, eventually welding them together.

[0033] The outer end of the machine body is provided with a release door plate 23 for opening and maintaining the welding mechanism 3. The inner end of the upper part of the machine body is provided with a belt stop switch 27. In use, the feeding belt and the welding and packing belt enter the feeding roller 8 and move forward along the channel, then complete a full circle in the 4-circle belt groove and return to the packing core to meet the belt stop switch 27 to complete the feeding. At this time, the pressure roller 7 performs the belt tightening action. After the packing belt is tightened, the welding mechanism 3 performs the cutting welding.

[0034] The top of the frame 1 is provided with a guide rail, and a sliding pressing block 24 is movably provided on the guide rail. A pressing rod 25 is hinged to the lower part of the sliding pressing block 24, and a pressing support seat 26 is hinged to the pressing rod 25. A connecting shaft 4 is slidably hinged to one end of the pressing rod 25. A rotating shaft center bearing seat 5 is provided on the wheel seat of the feed roller 8. A tensioning roller rotating shaft 6 is provided at one end of the pressing roller 7. One end of the tensioning roller rotating shaft 6 is connected to the connecting shaft 4, and the connecting shaft 4 is connected to the pressing support seat 26. The lower part of the connecting shaft 4 is hinged to the rotating shaft center bearing seat 5. In use, the sliding pressure block 24 moves, pulling the pressure rod 25. The pressure rod 25 pulls the pressure support 26, the connecting shaft 4, and the tensioning wheel rotation shaft 6, thereby pressing the pressure wheel 7.

The hinge point of the rotation is connected to the angle measuring sensor. The torque is calculated according to the measured angle. After the pressure wheel 7 is tightened to the set torque, a feedback signal is sent to the cam drive motor 14 for subsequent operations.

[0035] This product uses a fully electric actuator:

When the belt reaches the belt switch 27, the cam group 10 rotates by an angle so that its first cam presses against the dynamic and static welding module 11. At this time, the upper belt is pressed down and the first angle signal of the cam group 10 is received. The clamping wheel 7 is tightened to the set torque and then fed back to the cam drive motor 14. The cam drive motor 14 receives the signal and the cam group 10 rotates by another angle, and the fourth cam presses down against the dynamic and static welding module 3 13. At the same time, the second cam of the cam group 10 presses down on the dynamic and static welding module 2 12. The dynamic and static welding module 3 13 presses down on the lower belt, and the dynamic and static welding module 2 12 cuts and presses down on the upper and lower layers of packing bags. The reciprocating welding motor 15 starts and moves back and forth with the lower friction plate 22 of the dynamic and static welding module 2 12 through the connector 16, so that the upper and lower belts rub and heat up and finally fuse together. In summary, multiple cam linkages are connected in series as a group and driven by a cam drive motor 14. The mechanism is compact and has extremely high stability. Meanwhile, the cam mechanism has a simple structure, few parts, small space occupation, accurate motion control law, high motion efficiency, and can complete a complete action in one rotation, and is easy to maintain.
