Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a self-propelled integrated machine for storing and baling green and yellow crops. Background Technology

[0002] Silage baling technology is a crucial step in modern mechanized agricultural and livestock operations. It primarily involves compacting, bagging, and sealing harvested silage or yellow silage for long-term storage and transportation. With the development of large-scale livestock farming, higher demands are being placed on the automation level, operational efficiency, and sealing reliability of baling equipment. Currently, the main types of balers on the market include stationary, towed, and self-propelled models, with self-propelled integrated balers gradually becoming the mainstream due to their combined harvesting, compaction, and bagging functions.

[0003] Current straw bale baling equipment typically uses pre-cut individual packaging bags (mostly polyethylene tubular bags) for filling straw bales. This method has significant technical limitations. A key pain point is the frequent bag replacement required during filling. After each bag is filled and sealed, the equipment must stop or slow down to complete empty bag replacement and positioning calibration, significantly reducing overall production efficiency and increasing start-up and shutdown losses as well as manual labor intensity. Furthermore, bag placement deviations are prone to occur during bag replacement, further affecting the accuracy of subsequent filling and sealing. Therefore, we propose a self-propelled integrated straw bale baling machine. Summary of the Invention

[0004] The purpose of this invention is to provide a self-propelled integrated baling machine for green and yellow silage, so as to solve the technical problem that existing independent baling bags need to be frequently changed and calibrated in the baling operation of green and yellow silage.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-propelled silage baling machine, comprising a silage baling machine body with a compaction mechanism, a silage cutting platform mechanism arranged on one side of the silage baling machine body, a bale outlet and a bale collector arranged on the silage baling machine body, a baling mechanism arranged on the bale outlet, and a guiding mechanism arranged on the bale collector. The baling mechanism is a ring array flattening and guiding structure, used to continuously flatten, guide, and prevent wrinkles in the bale bagging process. The guiding mechanism includes a guiding module and an extrusion module; The guiding module is located at the output end of the bag outlet. It gathers the bags at the hot shearing position and simultaneously heats the area to seal the unfilled ends of the bags, while separating the filled bags from the unfilled portions. The guiding module includes a rectangular frame with a sandwich layer. The rectangular frame is fixedly connected to the upper surface of the receiving platform, and the interior of the rectangular frame corresponds to the output end of the package outlet. The rectangular frame has two horizontally sliding first combined rods and two vertically sliding second combined rods arranged inside the interlayer, and the two first combined rods and the two second combined rods can move towards each other or in opposite directions. Each of the first combined rods is equipped with a first sector, and each of the second combined rods is equipped with a second sector. When the two first combined rods and the two second combined rods move towards each other, the two first sector and the two second sector converge to form a circular heating cylinder. This not only heat-shears the converged position of the packing bag but also seals the opening of the unfilled packing bag. The present invention continuously flattens and guides the bag body through the packing mechanism, and then uses the guiding module to converge the sector to form a heating cylinder to heat the bag body. Thus, while sealing and separating the filled section, it remelts the open end of the next packing bag to create a closed end. This achieves uninterrupted filling, sealing, and cutting of a continuous packing bag that is one-piece closed and one-open. This design solves the technical problems of existing continuous packing bags, where the bag body is prone to wrinkles and twists during transportation, affecting filling, and the inability to synchronously, efficiently, and reliably complete the sealing of the filling section and prepare a new closed end for the next bag section in continuous operation.

[0006] Preferably, the bag collector is composed of a receiving platform, a guide slide, a buffer device, and a support frame, etc. The receiving platform is located directly below the bale outlet and is used to receive the formed bales of straw. The guide slide plate is hinged to one side of the receiving platform to guide the bales of straw to slide down to the ground or the transfer position; Preferably, the outlet is composed of a cylindrical section and a rectangular section, and the interior of both the cylindrical section and the rectangular section is a rectangular flow space; The cylindrical section has an annular groove on its surface, which can hold packaging bags.

[0007] Preferably, the packaging mechanism includes several mounting plates, which are fixedly connected in a ring array to one side of the cylindrical section of the bag outlet. Each mounting plate is hinged with a support frame, which is elastically connected to the mounting plate via a first tension spring. One end of the support frame is rotatably connected to a cam via a rod, and the cam rolls in contact with the surface of the cylindrical section of the bag outlet. The surface of the cylindrical section of the bag outlet is connected in a ring array with several curved support rods via nuts and bolts. A guide ring is fitted onto the inner wall of one side of the cylindrical section of the bag outlet located in the annular groove. An annular flow channel is formed between the inner wall of one side of the annular groove and the guide ring, allowing the packaging bag to move smoothly.

[0008] Preferably, the ends of several of the curved support rods are rotatably connected to the surface of the guide ring, and each support frame has an oblong hole on both sides of its inner wall. The surface of the guide ring has a through hole corresponding to the position of the support frame. A guide post is slidably fitted inside each through hole, and the end of the hinge rod on each guide post is slidably adapted to the inside of the oblong hole.

[0009] Preferably, the guiding module further includes several guide rods. Each first combined rod consists of two opposing first inclined rods and two horizontal rods. Each second combined rod consists of two opposing second inclined rods and two vertical rods. The first sector is fixedly connected to the ends of the two opposing first combined rods, and the second sector is fixedly connected to the ends of the two opposing second inclined rods. Each first inclined rod has a first movable hole on one side, and each second inclined rod has a second movable hole on one side. A first movable cylinder with a spiral groove is hinged inside each first movable hole, and a second movable cylinder with a spiral groove is hinged inside each second movable hole. Each guide rod is arranged between adjacent first and second movable cylinders.

[0010] Preferably, each of the guide rods consists of a rubber rod and a rigid rod with helical blades fixed to both ends of the rubber rod, wherein the helical blades of one of the rigid rods are slidably adapted to the helical groove of the first movable cylinder, and the helical blades of the other rigid rod are slidably adapted to the helical groove of the second movable cylinder.

[0011] Preferably, the extrusion module includes several trapezoidal frames, each corresponding to the positions of the two first sector bodies and the two second sector bodies. The trapezoidal frames are fixedly connected in a rectangular array inside the interlayer of the rectangular frame, and the second and first inclined rods are both matched with the side surfaces of the rectangular frame corresponding to their positions.

[0012] Preferably, each trapezoidal frame has two movable slots and two waist-shaped slots in a symmetrical structure. Each movable slot has an arc-shaped groove on its inner wall on both sides. Each movable slot has a stop piece movably arranged inside it. The first protrusion on the stop piece is slidably adapted to the inside of the waist-shaped slot.

[0013] Preferably, the second protrusion on each of the abutments is slidably adapted to the inside of the arc-shaped groove, and a first spring is fixedly connected to each of the trapezoidal frames in the movable groove. The first spring is elastically connected to the abutment, and the abutment is in movable contact with the end of the rigid rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a packaging mechanism to continuously flatten and guide the bag body, and then uses a guiding module to gather the fan-shaped body to form a heating cylinder to heat the bag body. In this way, while sealing and separating the filled section, a new closed end is remelted for the open end of the next bag section. This achieves uninterrupted filling, sealing and cutting of a one-piece, one-end closed and one-end open continuous packaging bag. This design solves the technical problems of existing continuous packaging bags, which are prone to wrinkles and twists during transportation, affecting filling, and the inability to synchronously, efficiently and reliably complete the sealing of the filling section and prepare a new closed end for the next bag section in continuous operation.

[0015] 2. This invention utilizes the linkage design of cams, guide columns, and support frames to automatically generate reciprocating motion during the continuous movement of the packaging bag. This continuously applies localized compression and pushing action to the surface of the bag, effectively smoothing out wrinkles and dispersing accumulation. This ensures that the bag remains flat and orderly during output, avoiding entanglement and disorder that could affect subsequent heat sealing operations. This improves packaging quality and operational continuity, thus solving the technical problem of unstable heat sealing quality caused by wrinkles, entanglement, and disordered accumulation of packaging bags during continuous output.

[0016] 3. When the two first combined rods and the two second combined rods move towards each other, the linear motion is converted into rotational torque through the helical transmission of the first movable cylinder, the second movable cylinder and the guide rod. This drives the rubber rod to deflect in the opposite direction of the packing bag's movement, actively guiding the bag body before heat sealing. At the same time, the two first sector bodies and the two second sector bodies converge to form a circular heating cylinder. The heating element heats the bag body evenly, causing the unfilled end to solidify and seal, ensuring a firm and accurate seal. This solves the technical problems of difficulty in accurately controlling the heat sealing position and uneven heating leading to unstable sealing quality.

[0017] 4. When the combined rod moves in the reverse direction to reset, the end of the rigid rod contacts the abutment on the trapezoidal frame. The abutment generates a reaction force through its limiting action in the arc-shaped groove, causing the rigid rod to rotate inside the movable cylinder and drive the rubber rod back to its initial right-angle state. At the same time, the first spring provides elastic reset force, ensuring that the abutment can automatically reset after completing the limiting action. This allows the guide rod, the first sector, and the second sector of the entire guide module to be completely hidden within the rectangular frame interlayer, without interfering with the normal pushing out and bagging of the bales. This achieves rapid switching between the working state and the reset state, improving the equipment's space utilization and operational safety, thus solving the technical problems of difficult reset of the guide mechanism and large space occupation affecting the normal pushing out of the bales.

[0018] 5. This invention uses an integrated structure made of thermoplastic material, with one end closed and the other open, which is fitted onto the annular groove at the bag outlet. Continuous filling is achieved by pushing with a bundle of straw. When heated, the material can melt and bond together, so that the unfilled end solidifies after heating to form a new closed end, achieving continuous sealed packaging. This ensures the airtightness of the packaging and achieves uninterrupted supply of packaging materials, reducing material waste and lowering operating costs. It solves the technical problems of serious material waste, poor sealing, and inability to achieve continuous bag supply in traditional packaging methods. Attached Figure Description

Detailed Implementation

[0021] like Figures 1-2 As shown, the present invention relates to a self-propelled silage baling machine, comprising a silage baling machine body 1 with a compaction mechanism, a silage cutting platform mechanism 11 arranged on one side of the silage baling machine body 1, a bale outlet 12 and a bale collector 13 arranged on the silage baling machine body 1, a baling mechanism 2 arranged on the bale outlet 12, and a guiding mechanism 3 arranged on the bale collector 13.

[0022] Specifically, the main body 1 of the silage baler in this embodiment not only has a compaction mechanism (the compaction mechanism includes a pressing cylinder, a pressing plate and a baling chamber. The pressing cylinder drives the pressing plate to compact the material through a hydraulic system, and after forming bales, they are discharged through the bale outlet 12 to the bale collector 13), but also includes a walking system (including a chassis and a four-wheel walking device), a power system (including an engine and a hydraulic system) and a control system (arranged in the cab); the silage cutting platform mechanism (11) is used to complete crop cutting and conveying, and the whole machine realizes integrated operation of harvesting, chopping, compacting and baling; at the same time, the bale collector 13 mainly bales the silage baler. The silage baler 13 includes a receiving platform 131, a guide slide plate 132, a buffer device, and a support frame. The receiving platform 131 is located directly below the bale outlet 12 and is used to receive the formed bales. The guide slide plate 132 is hinged to one side of the receiving platform 131 to guide the bales to slide to the ground or transfer position. The buffer device (such as a spring, hydraulic buffer, or rubber pad) is set at the connection between the receiving platform 131 and the guide slide plate 132 to reduce the impact of the bales. The support frame is welded from steel profiles and is fixed to the frame of the silage baler 1 by bolts or welding to provide structural support for the entire bale collector 13.

[0023] Combination Figure 3As shown, in this embodiment, the package outlet 12 is composed of a cylindrical section and a rectangular section, and the internal flow space of the cylindrical section and the rectangular section is the same, both being rectangular flow spaces or both having rectangular cross sections; wherein, an annular groove 121 is provided on the surface of the cylindrical section for storing the packaging bag 4; like Figures 12-13 As shown, the packing bag 4 in this embodiment is an integral structure, with one end closed and the other end open. The open end is fitted onto the annular groove 121, and the closed end is located in the output direction of the outlet 12. After the compacted bale of straw is pushed out from the outlet 12, it falls into the packing bag 4 and pushes the packing bag 4 towards the closed end. Then, the bag opening of the filled part is heated to separate the filled and unfilled parts of the bag. The unfilled part solidifies after heating to form a new closed end, thereby realizing continuous packaging operation.

[0024] It is worth noting that the packing bag 4 described in this embodiment is made of thermoplastic material, such as low-density polyethylene, linear low-density polyethylene or its composite material; this material can melt and bond when heated, thereby solidifying to form a new closed end after heating, achieving continuous sealed packaging; and this material has both tensile strength and heat-sealing performance, ensuring that it is not easily damaged during the pushing and moving of the bales, while also forming a strong closed end after heating.

[0025] This invention employs an integrated structure made of thermoplastic material, with one end closed and the other open, fitted onto the annular groove 121 of the bag outlet 12. Continuous filling is achieved by pushing with a bundle of straw. The material can melt and bond when heated, causing the unfilled end to solidify and form a new closed end after heating, thus achieving continuous sealed packaging. This ensures both the airtightness of the packaging and the uninterrupted supply of packaging materials, reducing material waste and lowering operating costs. It solves the technical problems of serious material waste, poor sealing, and inability to achieve continuous bag supply in traditional packaging methods.

[0026] like Figures 3-4As shown, the packaging mechanism 2 in this embodiment includes several mounting base plates 21, which are fixedly connected in a ring array to one side of the cylindrical section of the outlet 12. Each mounting base plate 21 is hinged with a support frame 22, which is elastically connected to the mounting base plate 21 by a first tension spring 23. One end of the support frame 22 is rotatably connected to a cam 24 via a plug rod, and the cam 24 rolls in contact with the surface of the cylindrical section of the outlet 12. The surface of the cylindrical section of the outlet 12 is connected in a ring array with several curved support rods 25 by nuts and bolts. A guide ring 26 is fitted onto the inner wall of one side of the cylindrical section of the opening 12, located on the annular groove 121. An annular flow channel is formed between the inner wall of one side of the annular groove 121 and the guide ring 26, allowing the packaging bag 4 to move smoothly. The ends of several curved support rods 25 are rotatably connected to the surface of the guide ring 26. Each support frame 22 has a waist-shaped hole 27 on both sides of its inner wall. The surface of the guide ring 26 has a through hole 28 corresponding to the position of the support frame 22. A guide post 29 is slidably fitted inside each through hole 28. The end of the hinge rod on each guide post 29 is slidably adapted to the inside of the waist-shaped hole 27.

[0027] Specifically, when the compacted bales are pushed out of the outlet 12, the baling bag 4 fills the bales. During this process, the baling bag 4 moves at its closed end due to the filling, causing the baling bag 4 located in the annular groove 121 to move due to the pulling. The surface of the baling bag 4 first contacts the inner wall of the guide ring 26, which acts as a guide, then contacts the end of the guide post 29, and finally passes through the cam 24. The cam 24 rotates due to the movement of the baling bag 4. Since the surface of the cam 24 has a raised structure, during the rolling process, the support frame 22 reciprocates axially (i.e., swings around the hinge point of the mounting base 21), which applies a force to the guide post 29, causing the guide post 29 to move back and forth in the through hole 28. During the reciprocating movement, the end of the guide post 29 applies local compression and pushing action to the surface of the passing baling bag 4 with a regular frequency and stroke, effectively flattening the bag wrinkles and dispersing local accumulation, so that the baling bag 4 remains flat and orderly during continuous output, avoiding the impact of entanglement or accumulation disorder on subsequent filling and heat sealing operations.

[0028] This invention utilizes the linkage design of cam 24, guide column 29, and support frame 22 to automatically generate reciprocating motion during the continuous movement of the packaging bag 4. This continuously applies local compression and pushing action to the surface of the bag, effectively smoothing out wrinkles and dispersing accumulation. This ensures that the bag remains flat and orderly during the output process, avoiding entanglement and disorder that could affect subsequent heat sealing operations. This improves packaging quality and operational continuity, thus solving the technical problem of unstable heat sealing quality caused by wrinkles, entanglement, and disordered accumulation of packaging bags during continuous output.

[0029] like Figure 5As shown, the guiding mechanism 3 in this embodiment includes a guiding module 31 and a squeezing module 32. The guiding module 31 is located at the output end of the bag outlet 12. Its function is to gather the packing bag 4 (i.e., the shearing position) and heat the position to make the end of the unfilled packing bag 4 solidify and seal, while the filled packing bag 4 is separated from the unfilled part.

[0030] Combination Figures 6-8 and Figure 11 As shown, in this embodiment, the guide module 31 includes a rectangular frame 311 with a sandwich panel. The rectangular frame 311 is fixedly connected to the upper surface of the receiving platform 131, and the interior of the rectangular frame 311 corresponds to the output end of the bag outlet 12. The cross-section of the rectangular frame 311 is square, and its side length is greater than any side length of the cross-section of the bag outlet 12. Inside the sandwich panel of the rectangular frame 311, two horizontally sliding first combined rods 312 and two vertically sliding second combined rods 313 are arranged by pneumatic sliders. Each first combined rod 312 consists of two opposing first inclined rods 3121 and two horizontal rods. Each second combined rod 313 consists of two opposing second inclined rods 3131 and two vertical rods. The ends of the two opposing first combined rods 312 are all fixedly connected to a first sector 3122 equipped with a heating element. The ends of the two opposing second inclined rods 3131 are all fixedly connected to a second sector 3132 equipped with a heating element. When the two first sector 3122 and the two second sector 3132 converge, they can... The components are arranged in a circular heating cylinder shape to heat the packaging bag 4, causing the unfilled portion of the packaging bag 4 to solidify and seal, while simultaneously separating the filled portion from the unfilled portion. Each first inclined rod 3121 has a first movable hole 3123 on one side, and each second inclined rod 3131 has a second movable hole 3133 on one side. A first movable cylinder 314 with a spiral groove is hinged inside each first movable hole 3123, and a second movable cylinder 315 with a spiral groove is hinged inside each second movable hole 3133. A guide rod 316 is arranged between two adjacent first movable cylinders 314 and second movable cylinders 315. Each guide rod 316 consists of a rubber rod 3161 (i.e., conventional technology with elastic deformation characteristics) and a rigid rod 3162 with spiral blades fixed at both ends of the rubber rod 3161. The spiral blades of one rigid rod 3162 are slidably adapted to the spiral groove of the first movable cylinder 314, and the spiral blades of the other rigid rod 3162 are slidably adapted to the spiral groove of the second movable cylinder 315.

[0031] Specifically, when the two first combined rods 312 and the two second combined rods 313 move towards each other, the two first sector bodies 3122 and the two second sector bodies 3132 converge to form a circular heating cylinder. The rubber rods 3161 on each guide rod 316 deform under the influence of the force, and through the elastic deformation characteristics of the rubber rods 3161, a force can be applied to the two rigid rods 3162 at their ends. Each pair of rigid rods 3162 slides in the first movable cylinder 314 and the second movable cylinder 315 respectively, and is transformed by the movement of the spiral plate in the spiral groove, applying torque to the rigid rods 3162, which can drive the rubber rods 3161 on the two rigid rods 3162 to deflect in the same direction (this direction is opposite to the direction of the packing bag 4), gather the packing bags 4 that have not been in the circular heating cylinder, and then heat the packing bags 4 that have been in the circular heating cylinder, so that the ends of the unfilled packing bags 4 are condensed and sealed, while the filled packing bags 4 are separated from the unfilled parts.

[0032] When the two first combined rods 312 and the two second combined rods 313 move toward each other, the linear motion is converted into rotational torque through the helical transmission of the first movable cylinder 314, the second movable cylinder 315 and the guide rod 316. This drives the rubber rod 3161 to deflect in the opposite direction of the packing bag 4, actively guiding the bag body before heat sealing. At the same time, the two first sector bodies 3122 and the two second sector bodies 3132 converge to form a circular heating cylinder. The heating element heats the bag body evenly, causing the unfilled end to solidify and seal, ensuring a firm and accurate seal. This solves the technical problems of difficulty in accurately controlling the heat sealing position and unstable sealing quality caused by uneven heating.

[0033] Combination Figures 9-11 As shown, in this embodiment, the extrusion module 32 includes several trapezoidal frames 321, each corresponding to the positions of two first sector bodies 3122 and two second sector bodies 3132. The trapezoidal frames 321 are fixedly connected in a rectangular array inside the interlayer of the rectangular frame 311. The second inclined rod 3131 and the first inclined rod 3121 are both matched with the side surface of the rectangular frame 311 corresponding to their positions. Each trapezoidal frame 321 has two movable slots and two waist-shaped slots in a symmetrical structure. Each movable slot has an arc-shaped slot 3211 on its inner wall on both sides. Each movable slot has a movably arranged abutment 322. The first protrusion on the abutment 322 slides and adapts to the inside of the waist-shaped slot. The second protrusion on each abutment 322 slides and adapts to the inside of the arc-shaped slot 3211. Each trapezoidal frame 321 is fixedly connected to a first spring 323 located in the movable slot. The first spring 323 is elastically connected to the abutment 322. The abutment 322 is in movable contact with the end of the rigid rod 3162.

[0034] Specifically, when the two first combined rods 312 and the two second combined rods 313 move in opposite directions, the rubber rod 3161 elastically deforms. When the end of the rigid rod 3162 comes into contact with the abutment 322, the abutment 322 rotates axially due to the force, and one side of the abutment 322 is in a horizontal state, fitting against the inner wall of the movable groove on the trapezoidal frame 321 (e.g., Figure 11 As shown), the rigid rod 3162 rotates within the second movable cylinder 315 due to the reaction force generated by the lack of movement space of the abutment 322, which can offset the rubber rod 3161 on the guide rod 316 to its initial state (as shown). Figure 11 As shown), the two rigid rods 3162 are in a horizontal and vertical state, while the rubber rod 3161 is in a right-angle state. The vertical rubber rod 3161 and the horizontal rubber rod 3161 are parallel to the first combined rod 312 and the second combined rod 313 that move in an intersecting manner. When the first combined rod 312 and the second combined rod 313 are completely inserted into the interlayer of the rectangular frame 311, the right-angled rubber rod 3161 is hidden inside the interlayer of the rectangular frame 311. The first sector 3122 and the second sector 3132 are both matched with the trapezoidal frame 321 and are hidden inside the interlayer of the rectangular frame 311.

[0035] When the combined rod moves in the reverse direction to reset, the end of the rigid rod 3162 contacts the abutment 322 on the trapezoidal frame 321. The abutment 322 generates a reaction force through its limiting action in the arc groove 3211, causing the rigid rod 3162 to rotate in the movable cylinder and drive the rubber rod 3161 back to its initial right angle state. At the same time, the first spring 323 provides an elastic reset force to ensure that the abutment 322 can automatically reset after completing the limiting action. This allows the guide rod 316, the first sector 3122, and the second sector 3132 of the entire guide module 31 to be completely hidden in the rectangular frame 311 interlayer, without interfering with the normal push-out and bagging operation of the bales. This achieves rapid switching between the working state and the reset state, improves the space utilization of the equipment and the safety of operation, and solves the technical problems of difficult reset of the guide mechanism and large space occupation affecting the normal push-out operation of the bales.

[0036] Working principle: This embodiment provides a self-propelled silage baling machine. When the silage cutting platform mechanism 11 completes the cutting and conveying of the crop, the material enters the main body 1 of the silage baler. The compaction mechanism inside then works, and the pressing cylinder drives the pressing plate to compact the material in the baling chamber to form a tight bale. The formed bale is discharged through the bale outlet 12.

[0037] The bale of straw is fed into the packing bag 4 and pushed towards the closed end. During this process, the closed end of the packing bag 4 moves due to the filling, causing the packing bag 4 located in the annular groove 121 to move due to the pulling. The surface of the packing bag 4 first contacts the inner wall of the guide ring 26, which acts as a guide, then contacts the end of the guide post 29, and finally passes through the cam 24. The cam 24 rotates due to the movement of the packing bag 4. Since the surface of the cam 24 has a raised structure, the support frame 22 reciprocates axially during the rolling process (i.e., swings around the hinge point of the mounting base 21), which applies a force to the guide post 29, causing the guide post 29 to move back and forth in the through hole 28. During the reciprocating movement, the end of the guide post 29 applies local compression and pushing action to the surface of the packing bag 4 with a regular frequency and stroke, effectively flattening the bag wrinkles and dispersing local accumulation, so that the packing bag 4 remains flat and orderly during continuous output, avoiding the impact of entanglement or accumulation disorder on subsequent filling and heat sealing operations.

[0038] During hot shearing, an external control system drives two first combined rods 312 and two second combined rods 313 to move towards each other, causing the two first sector-shaped bodies 3122 and the two second sector-shaped bodies 3132 to converge into a circular heating cylinder. At this time, the rubber rods 3161 on each guide rod 316 are compressed and undergo elastic deformation. Through the rigid rods 3162 at both ends, they slide in the spiral grooves of the first movable cylinder 314 and the second movable cylinder 315 respectively, converting linear motion into rotational torque. This drives the two rigid rods 3162 to cause the rubber rods 3161 to deflect in the same direction (opposite to the direction of movement of the packaging bag 4), thus guiding the packaging bag 4 that has not yet been heated. Subsequently, when the packaging bag 4 passes through the circular heating cylinder, the heating element heats the bag body. Heat sealing is performed to seal the ends of the unfilled bale bags by heat. At the same time, the filled portion separates from the unfilled portion due to the weight of the bale and the tilt of the guide slide plate 132, completing the heat shearing operation. When the control system drives the first combined rod 312 and the second combined rod 313 to move in opposite directions, the end of the rigid rod 3162 contacts the abutment 322 on the trapezoidal frame 321. The limiting action of the abutment 322 generates a reaction force, causing the rigid rod 3162 to rotate in the movable cylinder. This causes the rubber rod 3161 to return to its initial right-angle state and hide in the interlayer of the rectangular frame 311. The first sector 3122 and the second sector 3132 also retract into the interlayer along with the combined rod, completing the reset action without affecting the bale pushing and bagging operation.
