[0034] A working method of a baler includes the following steps:

[0035] The servo motor assembled by the power delay transmission mechanism starts to rotate forward to provide power. Then, the first gear transmits the power to the central rod A, and the threaded section (trapezoidal lead screw) provided on the central rod A rotates reversely; the central rod B transmits the power to the driving mechanism of the wire feeding structure through the second gear, the driven gear rotates forward, and the wire feeding structure starts to feed the wire; the baling wire extends from the wire inlet frame to the wire guide frame. The baling wire changes direction through the wire guiding gaps formed by multiple wire pressing wheels and pulleys, and passes through the wire pressing device. One end of the baling wire is guided by the gap between the last wire pressing wheel and the pulley and then leaves the wire guide frame and is sent out of the wire guide frame;

[0036] The baling wire leaving the wire guide frame enters the wire pipe provided at the front end of the upper wire path through the wire feeding structure; the baling wire passes through the upper wire path and the lower wire path and finally bypasses the object to be baled for a set number of turns;

[0037] While feeding the wire, the wire receiving cylinder works, driving the guide shaft, pulley, and wire pressing wheel fixed on the guide shaft fixing seat to move upward, preparing for the wire receiving of the wire receiving device; after the wire feeding length is controlled by the encoder assembled on the wire feeding structure, the servo motor stops running and the wire feeding stops;

[0038] The wire pressing device assembled on the wire guide frame works. The cylinder of the wire pressing device pushes the wire receiving pressing head, and the wire receiving pressing head and the wire receiving stop block press the baling wire tightly;

[0039] The servo motor rotates reversely. Driven by the forward rotation of the threaded section (trapezoidal lead screw), the two jaws connected to the end of the packing head rotating shaft move the packing head rotating shaft to the right through the nut, causing the two jaws to close and pull the baling wire into the two jaws. The wire receiving device starts to receive the wire: the wire receiving cylinder drives the guide shaft, pulley, and wire pressing wheel fixed on the guide shaft fixing seat in the wire receiving device to move downward, tightening the baling wire (when the whole wire receiving device moves downward, the baling wire will be pulled downward. Because the wire pressing device on the left has pressed the baling wire tightly, the baling wire on the right will be pulled downward to be tightened. At this time, the baling wire is tightened (during the wire receiving stage) and fits the bundled object, making the bundling effect better);

[0040] The lower wire channel cylinder expands and contracts. The cutter on the cutter seat extends driven by the cylinder connecting shaft, cylinder fixing pin, and cutter seat, moves within the lower wire channel, and the cutter cooperates with the fixed cutter installed beside it to squeeze and cut the tying wire and then retracts the cutter;

[0041] (During the wire retraction stage) The wire retraction device starts to retract the tying wire in the lower wire channel into the wire tube on the wire guide frame to prevent the operation of the equipment from being affected by the exposed tying wire;

[0042] As the servo motor continues to rotate in reverse, the threaded section connected to the center rod A rotates forward to drive the packing head rotating shaft and the two jaws to rotate. The tying wire located between the two jaws rotates and knots. After the knotting is completed, the servo motor rotates forward again, the two jaws open, and the rest of the components return to the original state to prepare for the next tying.

[0043] During installation or maintenance, through the expansion and contraction of the packing cylinder, the upper wire channel connected with the tying wire plastic block rotates up and down, and at the same time, the induction piece rotates to the proximity switch. The proximity switch obtains the in-place signal of the induction piece, and the moving base moves according to the in-place signal for easy maintenance.

[0044] The beneficial effects of the present invention are:

[0045] The overall structure of the tying machine jaws is compact, integrating the control of jaw opening and closing and tying wire knotting; the wire feeding wheel has a small and simple structure, and in the power delay transmission mechanism of the present invention, the gear transmission can ensure a constant instantaneous transmission ratio, high smoothness, and accurate transmission action; the wire feeding wheel of the present invention has a small and simple structure.

[0046] The present invention installs a wire pressing frame on the core reel holder, which enables the tying wire to be transmitted upward orderly; a wire pressing device is provided at a set position on the wire guide frame, and the wire pressing device is used to prevent the tying wire from derailing; the wire retraction device is used to pull the tying wire downward, that is, to retract the other end of the tying wire passing through the wire guiding device; the pulley and wire pressing wheel are used for guiding and anti-derailing of the tying wire; a motor dust cover is also installed on the packing head base to protect the power delay transmission mechanism, jaw structure, and motor; a linear bearing is installed on the wire retraction cylinder bottom plate, and the linear bearing is used to guide the guide shaft on the guide shaft fixing seat.

[0047] The tying machine of the present invention adopts pneumatic control, with quick and convenient actions, more automatic and intelligent; the tying machine designed by the present invention has a high utilization rate of site space; the components and working media used in the present invention have low costs and are convenient for the automation modification of existing machinery and equipment; the tying machine of the present invention has strong adaptability: it can work in harsh environments such as flammable, explosive, dusty, humid, and impact, and can work reliably in environments with a wide temperature range, humidity, and dust.

[0092] During operation, the driving force of other components and the driving mechanism 5.2.2 (i.e., the bevel gear in the figure) can drive the driving gear 5.9 to rotate. The driving gear 5.9 drives the driven gear 5.7 to rotate. The moving rod 5.5 pushes out the slider 5.1.3 under the action of the spring 5.1.8. Since the driven gear 5.7 is fixed on the slider 5.1.3, the driven gear 5.7 and the driving gear 5.9 are pressed tightly together. The packing line passes through the passage 5.1.2 formed by the grooves 5.8 of the driven gear 5.7 and the driving gear 5.9. When the driving gear 5.9 and the driven gear 5.7 rotate, they drive the packing line to be received and sent.

[0097] For the jaw structure 6:

[0098] The jaw structure 6 includes a center rod A 6.1, on which a threaded section 6.5 is provided. The threaded section 6.5 is a trapezoidal lead screw, and a nut 6.2 is screwed on the threaded section 6.5. A hollow packing head rotating shaft 6.7 is sleeved outside the center rod A 6.1. One end of the packing head rotating shaft 6.7 is connected to the nut 6.2 and the other end is connected to two jaws 6.1.1. After the two jaws 6.1.1 are closed, a wire clamping opening 6.1.8 is formed. A first rotating shaft 6.1.6 is provided on each of the two jaws 6.1.1, and both ends of the first rotating shaft 6.1.6 are connected to the packing head rotating shaft 6.7. A second rotating shaft 6.9 is also provided on each of the two jaws 6.1.1. At the end of the center rod A 6.1 where the jaws are located, a packing head fixed shaft 6.8 that can rotate circumferentially around the center rod A 6.1 is provided. Waist-shaped holes 6.1.3 for limiting both ends of the second rotating shaft 6.9 are provided on the packing head fixed shaft 6.8, and the second rotating shaft 6.9 can move in the waist-shaped holes 6.1.3; a lead screw retaining ring 6.6 for restricting the nut 6.2 from continuing to move towards the jaw 6.1.1 end is fixed on the center rod A 6.1, and a limiting mechanism 6.4 for restricting the rotation of the nut 6.2 or the packing head rotating shaft 6.7 is also provided on the nut 6.2 or the packing head rotating shaft 6.7; the limiting mechanism 6.4 includes a blocking wheel 6.3 connected to the nut 6.2 or the packing head rotating shaft 6.7. On the blocking wheel 6.3, a rib 6.2.2 arranged along the length direction of the center rod A 6.1 and a convex block 6.2.1 are provided. There is a gap between the convex block 6.2.1 and the rib 6.2.2, and the length of the convex block 6.2.1 is less than the length of the rib 6.2.2.

[0099] Waist-shaped holes 6.1.3 for inserting the end of the center rod A 6.1 are provided on the packing head fixed shaft 6.8. A spring 6.1.4 is provided in the waist-shaped holes 6.1.3, and a limiting component 6.1.2 for restricting the end of the center rod A 6.1 from slipping out is provided in the waist-shaped holes 6.1.3.

[0100] The packing head rotating shaft 6.7 is provided with a notch for inserting two clamping jaws 6.1.1. The clamping jaws 6.1.1 are provided with a chamfer 6.1.5 at the outer edge of the bottom of the notch. The outer end of the clamping jaws 6.1.1 is provided with a hook section 6.1.9 to prevent the tying wire from slipping out. The two clamping jaws 6.1.1 are engaged through a concave-convex platform structure 6.1.7.

[0101] During operation: Power is supplied to the central rod A 6.1. When the central rod A 6.1 rotates in one direction, the limiting mechanism 6.4 restricts the rotation of the packing head rotating shaft 6.7. When the limiting mechanism 6.4 restricts, an external component can block at the rib 6.2.2 but is not stuck by the convex block 6.2.1. The packing head rotating shaft 6.7 moves towards the end away from the clamping jaws 6.1.1, and the first rotating shaft 6.1.6 also moves accordingly. The second rotating shafts 6.9 move from both ends of the kidney-shaped hole 6.1.3 to the center respectively, and the two clamping jaws 6.1.1 open. The packing wire is inserted into the wire clamping port 6.1.8. Since the external component does not move, at this time, the external component is stuck between the rib 6.2.2 and the convex block 6.2.1. When the central rod A 6.1 rotates in the other direction, the limiting mechanism 6.4 restricts the rotation of the packing head rotating shaft 6.7. The packing head rotating shaft 6.7 moves towards the end close to the clamping jaws 6.1.1, and the first rotating shaft 6.1.6 also moves accordingly. The second rotating shafts 6.9 move from the center of the kidney-shaped hole 6.1.3 to both ends respectively, and the two clamping jaws 6.1.1 close; The limiting mechanism moves to a position without the convex block 6.2.1. Since the central rod A 6.1 rotates in a different direction at this time, the external component does not rotate towards the rib 6.2.2 side. The packing head rotating shaft 6.7 continues to move until it is blocked by the screw rod retaining ring 6.6 and then rotates together with the central rod A 6.1, and the two clamping jaws 6.1.1 perform kinking.

[0102] The wire take-up device 2 includes a wire take-up cylinder 2.1, and the wire take-up cylinder 2.1 is fixed to the wire guide frame 1.0 through a wire take-up cylinder bottom plate 2.2;

[0103] A linear bearing 2.3 is installed on the wire take-up cylinder bottom plate 2.2, and the linear bearing is used to guide the guide shaft on the guide shaft fixing seat; A magnetic switch 2.9 is also installed on the wire take-up cylinder 2.1, and the magnetic switch 2.9 is used to control the wire take-up cylinder 2.1 to achieve automatic control through electrical equipment.

[0104] The wire take-up cylinder bottom plate 2.2 is also provided with an adjustment device (hexagon socket head cap screw) for adjusting the maximum descending position of the wire take-up cylinder 2.1, that is, adjusting the length of the tying wire for wire take-up.

[0105] Regarding the power delay transmission mechanism 7:

[0106] The power delay transmission mechanism 7 includes a central rod B 7.6, on which a first gear 7.3 and a second gear 7.1 are mounted and axially limited. The first gear 7.3 is a driven gear and the second gear 7.1 is a bevel gear.

[0107] A delay transmission assembly is provided between the first gear 7.3 and the second gear 7.1. The delay transmission assembly includes an arc-shaped groove 7.4 and a plug 7.5 inserted into the arc-shaped groove 7.4. The arc-shaped groove 7.4 is a major arc structure. The arc-shaped groove 7.4 and the plug 7.5 inserted into the arc-shaped groove 7.4 are respectively located on the first gear 7.3 and the second gear 7.1.

[0108] One or more power wheels 7.2 are further provided between the central rod B 7.6 and the first gear 7.3 and the second gear 7.1. Delay transmission assemblies are provided between the first gear 7.3 and the power wheel 7.2, between the power wheels 7.2, and between the power wheel 7.2 and the second gear 7.1.

[0109] During operation, by providing a jaw structure 6 on the central rod B 7.6, an external power drives the first gear 7.3. The jaw structure 6 can open, close, and twist. The wire winding and wire feeding devices are controlled by the second gear 7.1. Due to the power delay between the first gear 7.3 and the second gear 7.1, there will be a time difference between the jaw structure 6 and the wire winding and wire feeding.

[0110] When the first gear 7.3 rotates forward, the plug 7.5 will move from one end of the arc-shaped groove 7.4 to the other end, and then drive a power wheel 7.2 to rotate. Similarly, until the second gear 7.1 rotates, that is, the power is transmitted to the wire winding and wire feeding devices to start wire winding. A time difference is generated during the rotation of the first gear 7.3 to the rotation of the second gear 7.1 (from jaw closure to the start of wire winding), that is, the time required for jaw closure. The small baler precisely calculates this, and this design is for the purpose of achieving efficient operation (time connection); conversely, the total time for all plugs 7.5 to move from the other end of the arc-shaped groove 7.4 to one end is the time for jaw opening. During this period, the wire winding and wire feeding devices do not move. After the jaws open, it is exactly the start of the forward rotation of the wire winding and wire feeding devices, that is, the whole machine waits for the next bailing.

[0111] The moving base 8 includes a base 8.1, front and rear guide rails 8.2, rollers 8.3, a moving base cylinder 8.4, a drag chain 8.5, a roller mounting plate 8.6, front and rear positioning blocks 8.7, roller baffles 8.8, an induction sheet 8.9, a proximity switch 8.9.1, and a speed control valve 8.4.1; the base 8.1 and the rollers 8.3 are installed on the front and rear guide rails 8.2 through the roller mounting plate 8.6 and the front and rear positioning blocks 8.7, and the moving base cylinder 8.4 is used to drive the base 8.1 to move on the front and rear guide rails 8.2; a sensor for controlling and positioning the rollers 8.3 is installed on the base 8.1, and the sensor is electrically connected to the proximity switch 8.9.1 to achieve the automation of the equipment; the moving base cylinder 8.4, the drag chain 8.5 (the drag chain is used to protect the air pipes and lines and make the cable arrangement more beautiful), and the front and rear guide rails 8.2 are all fixed on the base 8.1, one end of the drag chain 8.5 is fixedly connected to the outer shell of the moving base cylinder 8.4, and the other end of the drag chain 8.5 is fixedly connected to the front and rear guide rails 8.2; roller baffles 8.8 for preventing the rollers 8.3 from exceeding the range of the front and rear guide rails 8.2 are installed at both ends of the front and rear guide rails 8.2; an induction sheet 8.9 is also installed on the front and rear guide rails 8.2, and 3 maintenance covers 10 are also provided on the base 8.1 for easy maintenance; the speed control valve 8.4.1 is used to adjust the telescopic speed of the moving base cylinder 8.4.

[0112] Embodiment 2

[0113] On the basis of Embodiment 1, the working method of the bundling machine includes the following steps:

[0114] The servo motor assembled by the power delay transmission mechanism 7 starts to rotate forward to provide power, and then the power is transmitted to the central rod A 6.1 by the first gear 7.3, and the threaded section 6.5 (trapezoidal lead screw) provided on the central rod A 6.1 rotates reversely; the central rod B 7.6 transmits the power to the driving mechanism 5.2.2 of the wire feeding structure 5 through the second gear 7.1, the driven gear 5.7 rotates forward, and the wire feeding structure 5 starts to feed the wire; the bundling wire 1.1 extends to the wire guide 1.0 through the wire inlet frame 1.3, and the bundling wire 1.1 changes its direction through the wire guide gap formed by a plurality of pressure wheels 1.4 and pulleys 3, and passes through the wire pressing device 1.5. One end of the bundling wire 1.1 is guided through the gap between the last pressure wheel 1.4 and the pulley 3 and then leaves the wire guide 1.0 and is sent out of the wire guide 1.0;

[0115] The bundling wire 1.1 leaving the wire guide 1.0 enters the wire pipe 1.0.1 provided at the front end of the upper wire channel 4.1 through the wire feeding structure 5; the bundling wire 1.1 passes through the upper wire channel 4.1 and the lower wire channel 4.2 and finally bypasses the object to be bundled for a set number of turns;

[0116] While feeding the wire, the take-up cylinder 2.1 works, driving the guide shaft 2.8, pulley 3, and wire pressing wheel 1.4 fixed on the guide shaft fixing seat 2.4 to move upward, preparing for the wire take-up of the wire take-up device 1.6; after the encoder 5.2 on the wire feeding structure 5 controls the wire feeding length, the servo motor stops running and the wire feeding stops;

[0117] The wire pressing device 1.5 assembled on the wire carrier 1.0 works, and the cylinder 1.5.4 of the wire pressing device 1.5 pushes the wire take-up pressure head 1.5.1, and the wire take-up pressure head 1.5.1 and the wire take-up stopper 1.5.2 clamp the bundling wire 1.1;

[0118] The servo motor rotates in reverse. Driven by the forward rotation of the threaded section 6.5 (trapezoidal lead screw) at the end of the packing head rotating shaft 6.7, the nut 6.2 drives the packing head rotating shaft 6.7 to move to the right, causing the two jaws 6.1.1 to close and pull the bundling wire 1.1 into the two jaws 6.1.1, and the wire take-up device 1.6 starts to take up the wire: the take-up cylinder 2.1 drives the guide shaft 2.8, pulley 3, and wire pressing wheel 1.4 fixed on the guide shaft fixing seat 2.4 in the wire take-up device 1.6 to move downward, tightening the bundling wire (when the whole wire take-up device moves downward, the bundling wire will be pulled downward. Because the wire pressing device on the left has clamped the bundling wire, the bundling wire on the right will be pulled downward for tightening. At this time, the bundling wire is tightened (the first stage of wire take-up) and fits the bundled object, making the bundling effect better);

[0119] The lower wire channel cylinder 4.2.1 expands and contracts, and the cutter 4.2.6 provided on the cutter seat 4.2.5 extends under the drive of the cylinder connecting shaft 4.2.3, cylinder fixing pin 4.2.4, and cutter seat 4.2.5, moves in the lower wire channel 4.2, and the cutter 4.2.6 cooperates with the fixed cutter 4.2.8 installed beside it to squeeze and cut off the bundling wire 1.1 and then retracts the cutter 4.2.6;

[0120] (In the second stage of wire take-up) The wire take-up device 1.6 starts to take up the wire, retracting the bundling wire 1.1 in the lower wire channel 4.2 into the wire tube 1.0.1 on the wire carrier 1.0 to avoid affecting the operation of the equipment due to the exposed bundling wire;

[0121] With the continuous reverse rotation of the servo motor, the forward rotation of the threaded section 6.5 connected to the center rod A 6.1 drives the packing head rotating shaft 6.7 and the two jaws 6.1.1 to rotate. The bundling wire 1.1 located between the two jaws 6.1.1 rotates and kinks. After the kinking is completed, the servo motor rotates forward again, the two jaws 6.1.1 open, and the rest of the components return to the original state, preparing for the next bundling.

[0122] During installation or maintenance, by extending and retracting the packing cylinder 4.4, the upper wire channel 4.1 connected with the binding wire plastic block 4.1.2 rotates up and down, and at the same time, the induction piece 4.1.6 rotates to the proximity switch 4.1.5. The proximity switch 4.1.5 receives the in-place signal of the induction piece 4.1.6, and the moving base 8 moves according to the in-place signal to facilitate maintenance.

Delay transmission components are provided between the first gear and the power wheel, between the power wheels and the power wheels, and between the power wheels and the second gear.

10. A method for operating the baler according to any one of claims 1 to 9, characterized in that: The following steps are involved: The servo motor equipped with the power delay transmission mechanism starts forward to provide power, and then the power is transmitted to the center rod A by the No. 1 gear, and the threaded section set on the center rod A reverses; the center rod B transmits power to the driving mechanism of the wire feeding structure through the No. 2 gear, and the driven gear rotates forward, and the wire feeding structure starts to feed the wire; the baling wire is extended to the wire rack through the wire entry frame, and the baling wire changes direction through the wire gap formed by multiple wire pressing wheels and pulleys, and passes through the wire pressing device. One end of the baling wire is guided by the gap between the last wire pressing wheel and the pulley, and then leaves the wire rack and is sent out of the wire rack; The baling wire leaving the wire rack enters the wire tube provided at the front end of the upper wire track through the wire feeding structure; the baling wire passes through the upper wire track and the lower wire track, and finally goes around the baled object for a set number of turns; While feeding the wire, the wire-receiving cylinder works, driving the guide shaft, pulley and wire pressing wheel fixed on the guide shaft fixing seat to move upward, preparing for the wire-receiving device to take up the wire; after the encoder assembly on the wire-feeding structure controls the wire-feeding length, the servo motor stops running and stops feeding the wire; The wire pressing device installed on the wire rack works, and the cylinder of the wire pressing device pushes the wire taking-up pressure head, and the wire taking-up pressure head and the wire taking-up stopper press the baling wire tightly; The servo motor rotates in reverse direction, and the two clamping jaws connected to the end of the rotating shaft of the baling head are driven by the positive rotation of the threaded section. The nut drives the rotating shaft of the baling head to move rightward, so that the two clamping jaws are closed and the baling wire is pulled into the two clamping jaws. The wire-reeling device starts to reel in the wire: the wire-reeling cylinder drives the guide shaft, pulley, and wire-pressing wheel fixed on the guide shaft fixing seat in the wire-reeling device to move downward to tighten the baling wire; The cylinder of the lower wire track is extended and retracted, and the cutter set on the cutter seat is extended through the cylinder connecting shaft, the cylinder fixing pin and the cutter seat, and moves in the lower wire track. The cutter cooperates with the fixed cutter installed on the side to squeeze and cut the baling wire, and then the cutter is retracted; The wire reeling device starts to reel in the baling wire in the lower wire track into the wire tube on the wire rack; As the servo motor continues to reverse, the threaded section connected to the center rod A rotates forward to drive the rotating shaft of the baling head and the two clamps to rotate, and the baling wire located at the two clamps rotates and twists. After the twisting is completed, the servo motor rotates forward again, the two clamps open, and the other components return to the original state, ready for the next baling; During installation or maintenance, the upper wire track connected to the wire bundling plastic block rotates up and down through the extension and retraction of the baling cylinder, and at the same time the induction plate rotates to the proximity switch. The proximity switch receives the induction plate in-position signal, and the mobile base moves according to the in-position signal.
