[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] When bundling, the cable tie introduction mechanism guides the end of the cable tie into the guide rail, and the cable tie moves along the guide rail into the circular track formed by the outer frame of the track and the inner frame of the track. The cable tie is continuously introduced until the cable tie goes around the circular track for one circle and the end reaches the top of the pressure rod. At this time, the end forms an overlapping area with the cable tie from the guide port on the introduction side to the top of the hot melt rod, and the cable tie introduction mechanism stops the introduction action; the lifting device is started, the pressure rod presses the fixed end area upward, and the linear reciprocating drive mechanism drives the inner frame of the track to move to the entrance side away from the channel, and the cable tie is exposed. The vegetables are surrounded on the inside, and the cable tie introduction mechanism works to pull the cable tie back in reverse until the vegetables are tightened. At this time, the jacking device is further lifted upward, and the hot melt rod is lifted upward to overlap and press the cable tie on its upper side with the end. Under the action of the hot melt rod and the welding fuse on the platform, the overlapping area of the cable tie is dissolved and connected together, and the jacking device returns to its position; at the same time, the cable tie introduction mechanism continues to pull the cable tie back in reverse to break the cable tie on the outside of the welding part; the second linear reciprocating drive mechanism drives the platform to move to one side to disengage from the inside of the cable tie, and the bundling is completed.

The shape of the guide rail 13 matches the shape and size of the cable tie, providing a guide for the cable tie to be introduced into the annular track. Toward action; the cable tie is rolled on the outside of the tying machine and has nothing to do with the design concept of the present application, and is not described in detail in the present application; one end of the cable tie is connected to the cable tie introduction mechanism; the track outer frame 1 is provided with an opening corresponding to the end of the guide rail 13, and a pressure rod 18 and a hot melt rod 19 are provided at a position corresponding to the opening in the chassis 11, wherein the pressure rod 18 is close to the end of the guide rail 13, and a guide opening is provided at a position corresponding to the end of the guide rail 13 on the pressure rod 18; the hot melt rod 19 is provided on the side of the pressure rod 18 away from the end of the guide rail 13, the height of the hot melt rod 19 is lower than the height of the pressure rod 18, and a welding fuse 10 is provided on the top of the hot melt rod 19; a lifting device is connected to one side of the pressure rod 18 and the hot melt rod 19; a platform 23 is provided between the track inner frame 2 and the top of the pressure rod 18 and the hot melt rod 19, a welding fuse 10 is provided at the lower end of the platform 23, and one side of the platform 23 is fixedly connected to the linear reciprocating drive mechanism 2.
[0032] The initial position of the track inner frame 2 is located near the entrance side of the channel. After the vegetables are harvested, they are placed in the channel position on the track outer shell 5. When bundling, the cable tie introduction mechanism introduces the cable tie end into the guide rail 13, and the cable tie moves along the guide rail 13 through the guide port on the pressure rod 18 and the opening of the track outer frame 1 to enter the circular track formed by the track outer frame 1 and the track inner frame 2. The cable tie is continuously introduced until the cable tie wraps around the circular track for one circle and the end reaches the top of the pressure rod 18.

[0033] At present, the price of common balers on the market usually ranges from 4,000 yuan to 7,000 yuan. Since balers involve multiple parts and complex mechanical structures, they are prone to various faults such as poor hot melt bonding effect and inadequate transmission of the strapping belt. Due to the high failure rate, the maintenance and servicing costs are relatively high, making it difficult to popularize them on a large scale among small farms or vendors. The baler provided in the disclosed example of the present application has a lower manufacturing price and a smaller size. It can reduce the production cost, reduce the failure rate, and improve the bundling efficiency and quality while improving the collection efficiency. It can also be used in conjunction with other small agricultural machinery, making it easier to popularize them on a large scale among small farms or vendors.

When the inner frame 2 is located near the entrance side of the channel, the distance between the front side block 3 and the rear side block 4 is adapted to the width of the cable tie, and the side blocking and limiting effect of the front side block 3 and the rear side block 4 can prevent the cable tie from deviating in the circular track, so that the cable tie can move smoothly in the circular track; under the guidance of the guide bar 7 and the track mouth matching structure, the track inner frame 2 can be driven by a linear reciprocating drive mechanism to perform two-way reciprocating linear translation sliding toward the entrance side away from the channel or toward the entrance side close to the channel; it should be understood that the track outer frame 1 and the track inner frame 2 can also adopt other combinations to form a circular track.

Under the action of the hot melt rod 19 and the welding fuse 10 on the platform 23, the overlapping area of the cable tie is dissolved and connected together, and then motor three 20 drives the cam 27 to rotate to lower the roller 25 back to its position.
[0041] Furthermore, a limit switch is installed at the bottom of the platform 23 corresponding to the position of the hot melt rod 19. When the hot melt rod 19 reaches the bottom of the platform 23, the limit switch sends a signal to the motor 20, and the motor 20 stops further rotation and lifts upward to avoid damage to the equipment due to excessive movement intensity, while forming a closed-loop feedback of the action controlled by the program.
[0042] As a specific embodiment of the present invention, a slide rail is provided at the top of the bracket 34, and the back plate 231 connected to the rear side of the platform 23 is slidably connected to the slide rail; a threaded hole is provided on the back plate 231, and a motor 4 38 is fixedly installed on the side of the back plate 231 in the chassis 11 away from the entrance of the channel, and the motor 4 38 is installed on the auxiliary table 15, and the second screw rod 24 connected to the output end of the motor 4 38 is threadedly connected to the threaded hole on the back plate 231; after the cable tie is broken by the cable tie introduction mechanism, since the platform 23 is still within the tightening range of the cable tie, the motor 4 38 is started, and the output end of the motor 4 38 drives the second screw rod 24 to rotate, and under the action of the threaded cooperation, the back plate 231 retreats along the second screw rod 24, and drives the platform 23 to leave the inside of the cable tie.
[0043] The auxiliary table 15 provides support for the motor 1 9 and the motor 4 38. Since the strapping machine itself does not require parts with too strong strength, the auxiliary table 15 can be made of acrylic plate.
[0044] A bundling method according to an embodiment of the present invention is implemented according to a bundling machine according to an embodiment of the present invention. The initial position of the track inner frame 2 is located near the entrance side of the channel. The front side block 3 of the track outer frame 1, the track inner frame 2 and the rear side block 4 surround and form a circular track that can guide the tie. After the vegetables are harvested, they are placed on the channel position on the track outer shell 5, that is, the inner side of the track inner frame 2. First, the end of the tie is passed through the notch of the adjusting handle 2 30, and then the adjusting handle 2 30 is pressed to compress the compression spring 29. The adjusting handle 2 30 rotates with the pin shaft 31 as the central axis, and the synchronous wheel 1 32 moves away from the synchronous wheel 2 33. At this time, the end of the tie is passed between the synchronous wheel 1 32 and the synchronous wheel 2 33 and through the adjusting handle 1 The notch on 28 reaches the starting end of the guide rail 13, and the adjusting handle 2 30 is loosened, and the cable tie is pressed between the synchronous wheel 1 32 and the synchronous wheel 2 33; the motor 2 is started, and the output shaft of the motor 2 drives the synchronous wheel 2 33 to rotate and squeeze the cable tie, and the synchronous wheel 1 32 rotates synchronously, and the cable tie can be introduced into the guide rail 13; the cable tie moves along the guide rail 13 through the guide opening on the pressure rod 18 and the opening of the track outer frame 1 to enter the annular track formed by the track outer frame 1 and the track inner frame 2, and the cable tie is continuously introduced until the cable tie wraps around the annular track for one circle, and the end reaches the top of the pressure rod 18. At this time, the end forms an overlapping area with the cable tie from the guide opening on the introduction side to the top part of the hot melt rod 19, and the motor is turned off. 2. Start motor 3 20. The output end of motor 3 20 drives shaft 22 to rotate, thereby driving cam 27 to rotate. Cam 27 lifts roller 25. Under the action of long spring 17, when roller 25 lifts, pressure rod 18 first presses the end area of cable tie to the bottom end of platform 23 to fix the overlapping area of cable tie end. Start motor 1 9. Motor 1 9 can drive first screw rod 14 to rotate. Through thread matching structure, connecting plate 8 can move backward along first screw rod 14, thereby driving track inner frame 2 to retreat. Track inner frame 2 moves toward the entrance side away from the channel, cable tie is exposed and surrounds the vegetables on the inside. Start motor 2 to reverse it, pull the cable tie back in the opposite direction, until Until the vegetables are tightened, the cam 27 further lifts the roller 25 upward, and the hot melt rod 19 is lifted upward to overlap the cable tie on its upper side and press it tightly with the end to reach the bottom end of the platform 23. Under the action of the hot melt rod 19 and the welding fuse 10 on the platform 23, the overlapping areas of the cable tie are dissolved and connected together, and then the motor three 20 drives the cam 27 to rotate to lower the roller 25 back to its position; at the same time, the motor two continues to pull the cable tie back in the opposite direction to break the cable tie outside the welding part; at this time, the motor four 38 is started, and the output end of the motor four 38 drives the second screw rod 24 to rotate. Under the action of the threaded cooperation, the back plate 231 retreats along the second screw rod 24, and drives the platform 23 to separate from the inside of the cable tie, thus completing the bundling.
[0045] The entire bundling process can be fully automated by completing the pre-settings. The bundling process of “releasing – contraction – fixing – cutting” is realized through a compact control box control structure. This system provides a more complete process for the integration and automation of bundling, saving the output of human resources.
