Description

Technical Field

[0001] The present application relates to the field of baling machines, and in particular to a track device for baling machines. Background Art

[0002] The baler is mainly used to wrap and tighten items with strapping tape, and then connect the two ends of the strapping tape by hot melting or using buckles to ensure that the items will not be scattered during transportation or storage.

[0003] In the prior art, the baling machine includes a support frame, on which are provided a strapping frame, a conveying mechanism and a track mechanism. The strapping frame is used to install a strapping tape roll, and the conveying mechanism is used to extract the strapping tape from the strapping tape roll and convey the strapping tape to the track mechanism, so that the strapping tape makes a circle in the strapping tape channel, fixes the head end of the strapping tape, and then returns the strapping tape to be tightened through the conveying mechanism, packs the items, glues and fixes the two ends of the strapping tape, and finally cuts the other end of the strapping tape to complete the packaging of the items.

[0004] The existing track mechanism includes a conveyor track and a paddle rotatably mounted on the conveyor track. The paddle seals the conveyor track, and the strapping belt makes a circuit around the conveyor track. When the conveyor mechanism retracts and tightens the strapping belt on the conveyor track, the paddle is ejected by the strapping belt's own inertia, allowing the strapping belt to detach from the conveyor track and be packaged. This track mechanism relies on the strapping belt's own movement to detach from the conveyor track, resulting in a slow strap tightening speed and low packaging efficiency. Summary of the Invention

[0005] In order to improve the working efficiency of a baling machine, the present application provides a track device for a baling machine.

[0006] The present application provides a track device for a baler, which adopts the following technical solution: A track device for a baling machine includes a conveying track and a track driving mechanism. A conveying channel is provided on the conveying track. The conveying channel has a closed state and an open state. The conveying channel is used to convey the baling tape in the closed state. The track driving mechanism is used to drive the conveying channel to switch from the closed state to the open state. The conveying channel is used to detach the baling tape in the open state.

[0007] By adopting the above technical solution, the track driving mechanism drives the conveying track to move, thereby opening the conveying channel and allowing the strapping belt to detach from the conveying channel. At this time, the strapping belt is tightened by the conveying mechanism without relying on the strapping belt's own movement to detach from the conveying channel, thereby improving the tightening speed of the strapping belt and the working efficiency of the baler.

[0008] Optionally, it further includes a plugging member. The conveying channel penetrates through the side wall of the conveying track facing the plugging member. The plugging member is used to plug the conveying channel. The plugging member and the conveying track are arranged in a direction perpendicular to the conveying direction of the packing belt. The track driving mechanism is used to drive the conveying track to move along the arrangement direction of the plugging member and the conveying track.

[0009] By adopting the above technical solution, the track driving mechanism drives the conveying track away from the plugging member, thereby opening the plugging port. And during the movement of the conveying track, it moves relative to the packing belt, so that the packing belt is removed from the conveying channel through the plugging port. Compared with setting the conveying track as two rotating and opening / closing conveying plates, the movement of the conveying track is more convenient for the setting of the track driving mechanism.

[0010] Optionally, the track driving mechanism includes a driving source and a transmission assembly. There are multiple groups of the transmission assemblies. Each group of the transmission assemblies is correspondingly arranged with different sides of the conveying track. The driving source is used to drive the transmission assembly to move, and the transmission assembly is used to drive the conveying track to move.

[0011] By adopting the above technical solution, there are multiple groups of transmission assemblies. Each group of the transmission assemblies drives different sides of the conveying track to move. Compared with one group of transmission assemblies driving the entire conveying track to move, the torque is reduced, the driving is more stable, and the service life of the conveying track is improved.

[0012] Optionally, the transmission assembly includes a guide plate and a connecting plate. The guide plate includes a rotating part. The connecting plates are respectively rotatably connected to the rotating part and the plugging member. The driving source is a driving motor. The driving motor is used to drive the connecting plate to rotate. The guide plate is provided with a strip-shaped hole extending obliquely. The plugging member is provided with a sliding hole extending along the arrangement direction of the plugging member and the conveying track. The conveying track is provided with a sliding member. The sliding member is slidably arranged in the strip-shaped hole and the sliding hole.

[0013] By adopting the above technical solution, the driving motor drives the connecting plate to rotate, driving the guide plate to move, so that the sliding member slides in the strip-shaped hole, and the sliding hole guides the sliding of the sliding member, so that the conveying track moves to open the conveying channel. By the transmission assembly, the rotation of the driving motor is converted into the movement of the conveying track. Compared with driving by using a cylinder or an electric push rod, the control and driving of the driving motor are more stable.

[0014] Optionally, the cross-section of the conveying track is square. The track driving mechanism further includes a transmission rod and two groups of transmission plates. The transmission rod and the transmission plates are spaced along the conveying direction of the packing belt. The transmission rod is arranged parallel to the output shaft of the driving motor. The transmission rod is rotatably arranged on the plugging member. The two ends of the transmission rod are respectively rotatably connected to the adjacent connecting plates. The two ends of the transmission plate are respectively fixedly connected to the adjacent guide plates.

[0015] By adopting the above technical solution, multiple groups of transmission components are connected through the transmission rod and the transmission plate, and multiple groups of transmission components can be driven by only one drive motor, which saves energy and ensures stable and fast transmission.

[0016] Optionally, the track drive mechanism further includes a drive assembly, the drive assembly includes a cam plate and a connecting rod, the drive motor is used to drive the cam plate to rotate, the cam plate includes an eccentrically rotating connecting portion, and the connecting rod is rotatably connected to the connecting portion and the rotating portion respectively.

[0017] By adopting the above technical solution and arranging the drive assembly, the drive motor can be set at a suitable position, which facilitates the layout and installation of the drive motor and achieves a compact structure.

[0018] Optionally, a reset assembly is provided between the blocking member and the conveying track, and the reset assembly includes a reset spring, and the reset spring is used to drive the conveying channel to switch from an open state to a closed state.

[0019] By adopting the above technical solution, the reset spring drives the conveyor track to reset, which increases the reset speed of the conveyor track compared to the motor-driven reset of the conveyor track, further improving the packaging efficiency.

[0020] Optionally, the conveying track includes a conveying frame, the conveying channel is opened on the conveying frame, and guiding arc surfaces are formed on the four corners of the conveying frame.

[0021] By adopting the above technical solution, if there is an angular conveying channel, the strapping belt is likely to interfere and be blocked at the corners of the conveying channel, resulting in the strapping belt not passing smoothly. The guiding arc surface can better guide the strapping belt, and the strapping belt can be smoothly conveyed without setting up more driving sources.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying channel is opened by the track drive mechanism, which increases the tightening speed of the strapping belt and improves the working efficiency of the strapping machine; 2. Multiple transmission components reduce torque, make the drive more stable, and extend the service life of the conveyor track; 3. The return spring increases the return speed of the conveyor track, further improving packaging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Referring to Figure 2 and Figure 3, the track device for the bundling machine further includes a fixedly arranged blocking member 3. The blocking member 3 is in a frame shape and includes a blocking surface 32.

[0037] In other embodiments, the driving source 21 can be a cylinder, an oil cylinder or an electric push rod, etc., and any method that can drive the conveying track 1 to move can be used. In this case, there is no need to set up the driving assembly 25. In other embodiments, the driving assembly 25 can be not provided, and the output shaft of the driving motor 211 is directly rotatably connected to the rotating portion 223 of the guide plate 221.

[0038] Refer to Figure 5 And Figure 7 , there are four groups of transmission assemblies 22, and each group of transmission assemblies 22 corresponds to four different sides of the conveying track 1 respectively. The track driving mechanism 2 further includes two transmission plates 24 and a transmission rod 23. The two transmission plates 24 and a transmission rod 23 are spaced apart around the conveying track 1 along the conveying direction of the packing tape. The transmission plates 24 and the transmission rod 23 are used to connect adjacent transmission assemblies 22. The transmission rod 23 is arranged in parallel with the rotating rod 254, and the transmission plate 24 is arranged perpendicular to the transmission rod 23.

[0042] The implementation principle of the track device for a strapping machine in an embodiment of the present application is as follows: Before the strapping machine starts to strap an item, the conveying channel 11 is in a closed state. First, the packing tape on the packing tape roll is wound around the conveying track 1 in the conveying channel 11 for one circle, and the leading end of the packing tape is fixed. When the strapping machine straps an item, the driving motor 211 drives the rotating rod 254 to rotate, driving the cam disc 251 to rotate, and then driving the connecting rod 252 to swing. The connecting rod 252 drives the connecting plate 222 to rotate, thereby driving the guide plate 221 to move away from the connecting rod 252 and towards the conveying track 1. The sliding member 4 slides in the strip-shaped hole 224 and the sliding hole 31, and finally drives the conveying track 1 to move away from the plugging surface 32. At this time, the conveying channel 11 switches from the closed state to the open state; at the same time, when the guide plate 221 moves, it drives the adjacent guide plate 221 to move through the transmission plate 24. When the connecting plate 222 rotates, it drives the adjacent connecting plate 222 to rotate through the transmission rod 23, so as to realize the movement of four groups of transmission components 22 driven by one driving motor 211. Finally, the packing tape is tightened to strap the item.

[0043] This application relies on the track driving mechanism 2 to open the conveying channel 11, which improves the tightening speed of the packing tape and the working efficiency of the strapping machine.

[0044] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
