Description

Technical Field

[0001] The invention belongs to the technical field of gardening, and in particular relates to a wire reel for a strapping machine and a strapping machine with the wire reel. Background Art

[0002] At present, when doing gardening, plants need to be tied together with wires or ropes. The traditional method is to manually tie the ties to the plants. On the one hand, the workload is large, the efficiency is low and the cost is high; on the other hand, it will result in irregular bundling and rough texture.

[0003] To this end, for example, the Chinese utility model patent "Automatic Cable Tie Machine", whose patent number is ZL200920107921.2 (authorization announcement number is CN201457757U), discloses an automatic cable tie machine, including a frame, a starting device, a transmission cam, a wire binding device, a cutting device, a wire feeding device, a swing arm device, and a stopping device; the starting device on the frame is connected to the transmission cam; the transmission cam on the frame drives the swing arm device and the cutting device; the transmission cam is connected to the stopping device: the stopping device is connected to the wire feeding device. The working process is as follows: when the wire to be tied with a cable tie is placed in the wire release groove, the start control panel is touched and the start switch is closed, the cam starts to rotate in the positive direction, driving the wire tightening transmission link to drive the wire tightening swing arm to rotate in the direction of the wire tying device to rotate the cable tie to the wire tying device, and the wire is cut off by the cutter and lifted to the position of the wire tying device. At this time, the driving gear and the transmission gear drive the transmission synchronous wheel wire tying device to start rotating to tighten the wire, and the wire tightening swing arm starts to rotate toward the origin. When the transmission link in front of the cutter contacts the low point of the cam, the cutter mechanism returns to the origin, and the high point of the cam touches the stop control switch, the cam stops moving, the wire tying device stops and positions, and the cutter mechanism and the wire tightening swing arm return to the origin; after the tied wire is removed, the start switch is disconnected, and the wire feeding mechanism starts to feed the cable tie. After the cable tie is fed, the entire machine action is completed.

[0004] Although the above patent realizes the bundling of cable ties, it has the following defects:

[0005] 1. The tying wire is tightened by rotating the tying device. When the tying wire is misplaced or moves relative to the tying device, it is easy to fail to tighten (tie) the tying wire (tie);

[0006] 2. In practice, two motors are used to realize wire feeding (wire feeding) and wire tying (knotting). The electronic control module is complex and costly. It is necessary to reserve space for another motor, and the equipment is large in size.

[0007] Therefore, it is necessary to further improve the existing strapping machine. Summary of the invention

[0008] The first technical problem to be solved by the present invention is to provide a wire reel for a tying machine in response to the current status of the above-mentioned prior art, so as to prevent the movement of the cable tie so as to achieve the purpose of reliably tying the cable tie, and to prevent the damage to tender branches caused by the cable tie being clamped too tightly by the wire reel when the tied cable tie is removed.

[0009] The second technical problem to be solved by the present invention is to provide a strapping machine which can automatically clamp the cable tie and reliably tie the cable tie.

[0010] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a wire reel for a strapping machine, characterized in that it includes

[0011] The main body has a mounting hole at a position near the center thereof, and a limiting groove in the interior thereof is arranged at the periphery of the mounting hole and is connected to the mounting hole and extends in the circumferential direction;

[0012] A clamping jaw group, at least partially disposed on the outer periphery of the main body, and comprising two clamping jaws spaced apart in the circumferential direction, each of the clamping jaws comprising a fixed clamping plate and a movable clamping plate located inside the fixed clamping plate and arranged to move close to or away from the fixed clamping plate;

[0013] An actuating rod is inserted into the mounting hole and can rotate around its own axis;

[0014] Each of the movable clamping plates corresponds to one of the limit slots and at least one pushing portion, the pushing portion is arranged on the actuating rod and is located in the limit slot on the corresponding side, when the actuating rod is in a rotating state, the pushing portion moves in the corresponding limit slot to push the movable clamping plate on the corresponding side to move toward the fixed clamping plate to clamp the cable tie; and when the clamping claw is in a clamping state and the actuating rod continues to rotate, the pushing portion can drive the main body to rotate together;

[0015] Each of the movable clamping plates corresponds to at least one first elastic member, which acts on the corresponding movable clamping plate to always make the movable clamping plate have a tendency to move in a direction away from the fixed clamping plate.

[0016] In the above-mentioned process where the clamping jaws are in the clamping state and the actuating rod continues to rotate, there are multiple ways to realize that the pushing part drives the main body to rotate together. The method can be: the pushing part abuts against the corresponding side wall of the limiting groove on the corresponding side to drive the main body to rotate together; the method can also be: the pushing part abuts against the corresponding movable clamp to drive the main body to rotate together.

[0017] There are many forms of forming the pushing portion. A laterally protruding pushing portion may be directly formed on the outer peripheral wall of the actuating rod, or a detachable pushing rod may be provided on the actuating rod. However, preferably, the outer peripheral wall of the actuating rod has a through hole and a pushing rod inserted in the through hole, and the two ends of the pushing rod located outside the through hole are respectively pushing portions located in the limiting grooves on the corresponding sides.

[0018] The main body can be in the form of an integral molding or a split part. From the perspective of convenient setting of the movable splint, preferably, the main body includes a first seat body and a second seat body arranged in sequence from front to back along the length direction of the actuating rod, the limiting groove is located between the first seat body and the second seat body, the fixed splint is partially installed on the outer periphery of the first seat body, and a gap is left between the fixed splint and the first seat body, and the movable splint is arranged on the outer periphery of the second seat body, and is partially located in the gap.

[0019] In order to guide the movement of the movable splint and facilitate the accommodation of the first elastic member, two guide columns are provided on the movable splint, both extending in the direction of the mounting hole, and the two guide columns are connected by a connecting plate, and a receiving groove for accommodating the first elastic member is formed between the first seat body and the second seat body, and the first elastic member is a first spring, one end of the first spring is in contact with the outer end of the receiving groove, and the other end of the first spring is in contact with the connecting plate.

[0020] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a strapping machine with the above-mentioned wire reel, characterized in that it also includes a motor and a first transmission assembly for driving the wire reel to rotate, the power output end of the motor is connected to the first transmission assembly, and the power output end of the first transmission assembly can be connected to the end of the actuating rod away from the main body.

[0021] The first transmission member can be realized by two bevel gears meshing with each other, or by multiple gears meshing with each other. However, preferably, the first transmission component includes

[0022] A first bevel gear, disposed on the output shaft of the motor;

[0023] A transmission shaft extending in the left-right direction, with a second bevel gear meshing with the first bevel gear mounted on the left end thereof; and

[0024] The first transmission rod extends along the front-to-back direction and is located behind the actuating rod and is consistent with the extension direction of the actuating rod. The front end of the first transmission rod is connected to the rear end of the actuating rod through a second clutch, and the rear end of the first transmission rod is provided with a third bevel gear meshing with the second bevel gear.

[0025] In order to deliver the cable tie to the corresponding clamping jaw of the cable reel, a wire feeder and a second transmission assembly are also included for delivering the free end of the cable tie to the corresponding clamping jaw of the cable reel. The wire feeder is C-shaped and its opening faces the cable reel. The inner peripheral wall of the wire feeder is provided with an arc groove extending along its length direction for the cable tie to pass through. Along the conveying direction of the cable tie, the first end of the wire feeder is located downstream of one clamping jaw of the cable reel, and the second end of the wire feeder is located upstream of another clamping jaw of the cable reel. The right end of the transmission shaft is provided with a transmission member that intermittently acts on the second transmission assembly. The power output end of the second transmission assembly is rotatably connected to the first end of the wire feeder, and the second end of the wire feeder approaches or moves away from the corresponding clamping jaw of the cable reel. In this way, one end of the cable tie is delivered to one of the clamping jaws of the cable reel by the wire feeder, and the other end of the cable tie is located at the other clamping jaw of the cable reel, so as to achieve the clamping of the two ends of the cable tie, thereby driving the cable tie to rotate during the subsequent rotation of the cable reel and completing the knotting of the cable tie.

[0026] In order to selectively drive the transmission shaft to rotate as needed, and then achieve the purpose of wire feeding, the transmission shaft is connected to the second bevel gear through the first clutch, and the second transmission assembly includes

[0027] A rotating shaft, which is consistent with the extension direction of the transmission shaft;

[0028] A first connecting rod is vertically arranged and located behind the wire feeding member, and is mounted on the rotating shaft at a position adjacent to the center thereof and is arranged to rotate relative to the rotating shaft;

[0029] A second connecting rod, the rear end of which is rotatably connected to the upper end of the first connecting rod, and the front end of which is rotatably connected to the first end of the wire feeding member;

[0030] A convex portion is arranged at an eccentric position of the transmission member, and the lower end of the first connecting rod is located on the rotation path of the convex portion.

[0031] In order to realize the conveying and cutting of the cable tie, it also includes a conveying mechanism for conveying the cable tie to the first end of the wire feeder and a cutting mechanism for cutting the cable tie, and along the conveying direction of the cable tie, the cutting mechanism is located between the conveying mechanism and the wire feeder. In this way, the cable tie can be automatically conveyed to the wire reel and cut.

[0032] In order to detect whether there is material on the material roller, and to prevent the cable tie (material belt) from being stuck in the strapping machine and unable to be removed when the machine continues to work without material, that is, to reduce the difficulty of cleaning, the machine also includes a support, a controller, a prompter, a material roller wrapped with a cable tie, and a detection system for detecting whether there is material on the material roller. The material roller is installed on the support through a connecting shaft and is arranged to rotate relative to the support. The detection system includes a magnetic triggering member arranged on the outer surface of the material roller and a Hall sensor for sensing the magnetic field signal of the magnetic triggering member. There are at least two magnetic triggering members, which are arranged at intervals along the circumferential direction on the periphery of the connecting shaft. The Hall sensor is arranged on the support. The signal input end of the controller is connected to the signal output end of the Hall sensor. The prompter is electrically connected to the controller and sends a prompt message that the material roller has no material under the control of the controller. In this way, when there is no material, the material roller cannot rotate, and the Hall sensor cannot sense the magnetic induction signal of the magnetic triggering member. After receiving the signal that the material roller does not rotate, the controller controls the prompter to send a prompt message to remind the user to release the material.

[0033] Compared with the prior art, the advantages of the present invention are: the wire reel includes an actuating rod and two clamping jaws, each clamping jaw includes a fixed clamping plate and a movable clamping plate, and the movable clamping plate moves toward the fixed clamping plate through the push of the upper push portion when the actuating rod rotates, so that the two clamping jaws clamp the two ends of the material belt respectively. The existence of the push portion prevents the movable clamping plate from falling under the action of gravity when the wire reel is not rotating, so that the wire cannot pass through the gap between the movable clamping plate and the fixed clamping plate during wire feeding, thereby failing to complete the wire feeding action. When the clamping claw clamps the material belt and the actuating rod continues to rotate, it drives the entire wire reel to rotate, thereby completing the purpose of tying the cable tie. That is, when the wire reel rotates, the two ends of the cable tie are first clamped to prevent the cable tie from shaking during the rotation of the cable reel and failing to complete the knot or the knot is not tied in a standard manner and damaging the plant. When the actuating rod stops rotating, the movable splint is moved away from the fixed splint by the first elastic member to increase the gap between the two, preventing the cable reel from clamping the wire too tightly and damaging the tender branches when the tied cable tie is removed. The tied cable tie can then be easily removed without damaging the plant, and the structure of the entire cable reel is reliable and reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present invention is further described in detail below with reference to the accompanying drawings.

[0048] like Figures 1 to 13 As shown, the strapping machine of this embodiment includes an outer cover 09, a wire reel 01, a first elastic member, a second elastic member, a conveying mechanism 02, a wire feeding member 03, a cutting mechanism 04, a motor 51, a transmission member, a first transmission assembly 06, a second transmission assembly 07, a support 9, a controller, a prompter, a material roller 91 wrapped with a cable tie, and a detection system for detecting whether there is material in the material roller 91.

[0049] like Figure 1 and Figure 2As shown, the outer cover 09 includes a first shell 091 and a second shell 092 arranged on the left and right and a top shell 093 located on the top. The first shell 091, the second shell 092 and the top shell 093 enclose a containing space with both front and rear ends open. The cutting mechanism 04, the motor 51, the first transmission assembly 06 and the second transmission assembly 07 are all located in the above-mentioned containing space. A button 010 is provided on the outer cover 09, and the button 010 is electrically connected to the controller. A handle portion 094 for easy grip is formed at the lower portion of the first shell 091 and the second shell 092, and the motor 51 is installed in the internal space of the handle portion 094. The orientation of this embodiment refers to Figure 1 The direction indicated by the arrow.

[0050] like Figure 1 As shown, the support 9 is arranged at the front side of the outer cover 09, and the material roller 91 is installed on the support 9 through the connecting shaft extending along the left and right, and is arranged to rotate relative to the support 9. Specifically, when the material roller 91 is conveyed by the conveying mechanism 02, the cable tie pulls the material roller 91 to rotate. The aforementioned detection system includes a magnetic triggering member 911 arranged on the outer surface of the material roller 91 and a Hall sensor 92 for sensing the magnetic field signal of the magnetic triggering member 911. There are 12 magnetic triggering members 911, and they are evenly arranged at intervals along the circumference on the periphery of the connecting shaft. The magnetic triggering member in this embodiment is a magnet, and other magnetically triggered components can also be used. The Hall sensor 92 is arranged on the support 9 and is located inside the support 9. The signal input end of the controller is connected to the signal output end of the Hall sensor 92. The prompter is electrically connected to the controller, and under the control of the controller, a prompt message indicating that the material roller 91 is out of material is issued. The above prompter is a buzzer or an LED light. When the Hall sensor 92 senses a change in the magnetic field, there is a tie on the material roller 91 , and when the Hall sensor 92 does not sense a change in the magnetic field, there is no tie on the material roller 91 , that is, the material roller 91 does not rotate.

[0051] like Figures 2 to 8As shown, the conveying mechanism 02 is used to convey the cable tie on the material roller 91 to the wire feeder 03 and finally to the wire reel 01. The conveying mechanism 02 is located behind the wire reel 01 and upstream of the wire feeder 03. The wire reel 01 is equipped with an actuating rod 14 extending in the front-to-back direction, and rotates around its own axis under the drive of the first transmission assembly 06. The power output end of the above-mentioned motor 51 is connected to the first transmission assembly 06, and the power output end of the first transmission assembly 06 can be connected to the rear end of the actuating rod 14 away from the main body 1. The first transmission assembly 06 in this embodiment includes an intermediate transmission assembly, a transmission shaft 6 and a transmission mechanism 08. The power input end of the intermediate transmission assembly is connected to the motor 51, and the transmission shaft 6 extends in the left-right direction, and the transmission shaft 6 is selectively connected to the power output end of the intermediate transmission assembly through a first clutch. Specifically, the intermediate transmission assembly includes a first bevel gear 511 installed on the output shaft of the motor 51 and a second bevel gear 61 installed on the left end of the transmission shaft 6. The output shaft of the motor 51 extends upward, and the transmission shaft 6 is selectively connected to the second bevel gear 61 through the first clutch, and the second bevel gear 61 is meshed with the first bevel gear 511. In addition, two gears can be meshed to realize the form that the motor can drive the transmission shaft 6 to rotate. In this way, when the motor 51 rotates, the second bevel gear 6 is driven to mesh and rotate through the first bevel gear 511, and the transmission shaft 6 is selectively driven to rotate through the first clutch. The power input end of the above-mentioned transmission member is connected to the transmission shaft 6, and the power output end of the transmission member is connected to the conveying mechanism 02. Specifically, the transmission member is a transmission gear 62 installed on the transmission shaft 6, and the conveying mechanism 02 includes a bracket 20, a mounting shaft 23, a rotating shaft 21 and a support shaft 22. A mounting seat 011 is provided on the right side of the bracket 20, and the mounting seat 011 is arranged vertically, wherein the rotating shaft 21 is mounted on the mounting seat 011 and the fixed seat 4 described below. The support shaft 22 is mounted on the bracket 20, and is located on the rotating shaft 21, and both extend in the left and right directions. In this embodiment, there are two rotating shafts 21 and two supporting shafts 22, and each rotating shaft 21 is equipped with a driving roller 211 and a first gear 212 that can mesh with the transmission gear 62. Therefore, there are two driving rollers 211 and they are arranged at intervals along the front and back. Each supporting shaft 22 is equipped with a driven roller 221 located above the driving roller 211. Therefore, there are two driven rollers 221 and they are arranged at intervals along the front and back directions. The two driven rollers 221 are connected by a mounting member 222, and there is a conveying channel between the driven roller 221 and the driving roller 211 for the cable tie to pass through. The mounting shaft 23 is located between the two rotating shafts 21 and is arranged side by side with the rotating shafts 21. The mounting shaft 23 is provided with an intermediate gear 231 that meshes with both first gears 212.Thus, when the transmission shaft 6 rotates, the driving roller 211 is driven to rotate by the transmission gear 62, the first gear 212 and the intermediate gear 231, thereby driving the cable tie between the driving roller 211 and the driven roller 221 to be transported toward the wire feeder 03. During the transportation process of the cable tie, in order to prevent the driving roller and the driven roller from wearing the cable tie and causing the powder to block the transportation channel, the driving roller has a greater hardness than the driven roller, and the outer peripheral surfaces of both rollers have a texture to increase friction, and the driving roller and the driven roller are made of PVC.

[0052] In order to overcome the disadvantage of opening the outer cover for changing the wire, Figure 4 As shown, a vertically arranged driving rod 24 is provided on the above-mentioned installation shaft 23, the driving rod 24 is arc-shaped, and one end of the driving rod 24 is installed on the installation shaft 23, and a boss 223 is provided on the installation member 222, and the boss 223 is located on the rotation path of the driving rod 24, and the driven roller 221 is driven to move upward relative to the bracket 20 under the intermittent push of the driving rod 24, and when the bracket 20 is in the highest position, the driving rod 24 continues to rotate and is out of contact with the boss 223. In this way, when the button 010 controls the rotation of the motor 51, the driving rod 24 is used to move the driven roller 221 away from the driving roller 211, so that the cable tie can pass smoothly, avoiding the problem of opening the outer cover for changing the wire.

[0053] The mounting member 222 equipped with the driven roller 221 can move downward under its own gravity, or it can have a tendency to move downward under the action of the second elastic member. Specifically, the second elastic member acts on the mounting member 222 and always makes the mounting member 222 have a tendency to move downward. Figure 3 As shown, the second elastic member in this embodiment is a second spring 224, and the second spring 224 is located between the mounting member 222 and the bracket 20. Figure 7 As shown, when the mounting member 222 moves up and down, the support shaft 22 slides up and down relative to the bracket 20. The bracket 20 is provided with a strip hole 201 extending in the up and down direction at a position corresponding to the support shaft 22, and the support shaft 22 is located in the corresponding strip hole 201. In this way, the support shaft 22 is slidably arranged on the bracket 20 in the up and down direction.

[0054] The power input end of the transmission mechanism 08 of this embodiment is connected to the intermediate transmission assembly, and the power output end of the transmission mechanism 08 is selectively connected to the actuating rod 14 through the second clutch. Figure 6 and Figure 8As shown, the transmission mechanism 08 includes a third bevel gear 81 and a first transmission rod 8 located behind the actuating rod 14. The first transmission rod 8 and the actuating rod 14 extend in the same direction, and the front end of the first transmission rod 8 is connected to the rear end of the actuating rod 14 through the above-mentioned second clutch. The third bevel gear 81 is installed on the rear end of the first transmission rod 8 and meshes with the second bevel gear 61. In this way, under the transmission of the intermediate component, the third bevel gear 81 is driven to rotate through the second bevel gear 61, thereby driving the first transmission rod 8 to rotate, and selectively driving the actuating rod 14 to rotate through the second clutch. The first clutch in this embodiment is the first one-way bearing 65, and the second clutch is the second one-way bearing 83. The above-mentioned first one-way bearing 65 and the second one-way bearing 83 are both one-way bearings in the prior art, which will not be described in detail in this embodiment. In addition, the first clutch and the second clutch can also adopt electromagnetic clutches in the prior art, as long as selective connection can be achieved.

[0055] like Figures 9 to 12 As shown, the above-mentioned wire reel includes a main body 1, a clamping jaw group and an actuating rod 14 extending in the front-to-back direction. A mounting hole 100 for mounting the actuating rod 14 is provided near the center of the above-mentioned main body 1, and a limiting groove 101 is provided inside the main body 1 at the periphery of the mounting hole 100, which is connected to the mounting hole 100 and extends in the circumferential direction. In this embodiment, there are two limiting grooves 101, which are spaced apart in the circumferential direction. Fig.11 As shown, the main body 1 includes a first seat body 11 and a second seat body 12 arranged in sequence from front to back, and the limiting groove 101 is located between the first seat body 11 and the second seat body 12. Specifically, the first seat body 11 and the second seat body 12 are both provided with a first half groove and a second half groove arranged at intervals along the circumferential direction, and the first half grooves on the first seat body 11 and the second seat body 12 are matched to form a limiting groove 101, and the second half grooves on the first seat body 11 and the second seat body 12 are connected to form another limiting groove 101. In addition, the limiting groove 101 can also be completely formed on the first seat body 11 or the second seat body 12.

[0056] like Figures 8 to 12As shown, the above-mentioned clamping jaw group is partially arranged on the outer periphery of the main body 1, and includes two clamping jaws 13 arranged at intervals along the circumferential direction. The two clamping jaws 13 have the same structure. The following description takes one clamping jaw 13 as an example. The clamping jaw 13 includes a fixed clamping plate 131 and a movable clamping plate 132 located inside the fixed clamping plate 131 and moving close to the fixed clamping plate 131 under the push of the pushing portion 1411. A gap 130 for the cable tie to pass through is formed between the fixed clamping plate 131 and the movable clamping plate 132. The size of the gap 130 is adjusted by the movement of the movable clamping plate 132. The fixed clamping plate 131 is partially installed on the outer periphery of the first seat body 11, and a gap 15 is left between the fixed clamping plate 131 and the first seat body 11. The movable clamping plate 132 is arranged on the outer periphery of the second seat body 12, and is partially located in the gap 15. Each movable clamping plate 132 corresponds to a limiting groove 101 and a pushing portion 1411. The outer peripheral wall of the actuating rod 14 is provided with a through hole 140 and a push rod 141 passing through the through hole 140. The two ends of the push rod 141 outside the through hole 140 are respectively push parts 1411 located in the corresponding limit groove 101. In this way, when the actuating rod 14 is in a rotating state, the push part 1411 moves in the corresponding limit groove 101 to push the movable clamping plate 132 on the corresponding side to move toward the fixed clamping plate 131 to clamp the cable tie; and when the clamping claw 13 is in a clamping state and the actuating rod 14 continues to rotate, the push part 1411 can drive the main body 1 to rotate together.

[0057] In order to realize the movement of the movable clamping plate 132 away from the fixed clamping plate 131, the first elastic member acts on the corresponding movable clamping plate 132, and always makes the movable clamping plate 132 have a tendency to move away from the fixed clamping plate 131. Specifically, two guide posts 1321 are provided on the movable clamping plate 132, both extending toward the mounting hole 100. The two guide posts 1321 are connected by a connecting plate 1322. When the clamping jaws 13 are in a clamping state and the actuating rod 14 continues to rotate, the pushing portion 1411 abuts against the connecting plate 1322 and then drives the main body 1 to rotate together. A receiving groove 103 for receiving the first elastic member is formed between the first seat body 11 and the second seat body 12, such as Fig.10 As shown, the first elastic member is a first spring 16 , one end of the first spring 16 contacts the outer end of the receiving groove 103 , and the other end of the first spring 16 contacts the connecting plate 1322 .

[0058] like Figure 4 and Figure 5As shown, the wire feeder 03 in this embodiment delivers the free end of the cable tie to the corresponding jaw 13 of the cable reel 01 under the drive of the second transmission assembly 07. The second transmission assembly 07 is located on the right side of the bracket 20. The wire feeder 03 in this embodiment is C-shaped and its opening faces the cable reel 01, and an arc-shaped groove 31 extending along its length direction is provided on the inner peripheral wall of the wire feeder 03 for the cable tie to pass through. In this embodiment, during the process of wire feeding (delivering the cable tie), the two jaws 13 of the cable reel are arranged at intervals up and down, and along the conveying direction of the cable tie, the first end of the wire feeder 03 is located downstream of the gap 130 of the upper jaw 13, and the second end of the wire feeder 03 is located upstream of the gap 130 of the lower jaw 13. The above-mentioned transmission gear 62 acts intermittently on the second transmission assembly 07, and the power output end of the second transmission assembly 07 is rotationally connected to the first end of the wire feeder 03, and the second end of the wire feeder 03 approaches or moves away from the corresponding jaw 13 of the cable reel 01. As shown Figure 4 As shown, the second transmission assembly 07 includes a rotating shaft 21, a first connecting rod 71, a second connecting rod 72 and a fourth elastic member. The first connecting rod 71 is vertically arranged and located behind the wire feeding member 03. The first connecting rod 71 is installed on the rotating shaft 21 near the center and is arranged to rotate relative to the rotating shaft 21; the rear end of the second connecting rod 72 is rotationally connected to the upper end of the first connecting rod 71, the front end of the second connecting rod 72 is rotationally connected to the first end of the wire feeding member 03, and the rear end of the second connecting rod 72 is connected to the fourth elastic member. Figure 4 As shown, the fourth elastic member is a fourth spring 73 mounted on the mounting seat 011, and the fourth spring 73 always makes the second connecting rod 72 have a tendency to move forward. A convex portion 621 is provided at an eccentric position on the right surface of the transmission gear 62, and the lower end of the first connecting rod 71 is located on the rotation path of the convex portion 621. In this way, when the transmission gear 62 rotates, the convex portion 621 rotates with the transmission gear 62 to push the lower end of the first connecting rod 71 to rotate forward, thereby driving the upper end of the first connecting rod 71 to rotate backward, so as to realize the second end of the wire feeding member 03 moving away from the lower clamping claw 13. In this way, the cable tie passes through the gap 130 of the upper jaw 13, the first end of the wire feeder 03, the arc groove 31, the second end of the wire feeder 03, and the gap 130 of the lower jaw 13 in sequence. When the actuating rod 14 rotates, the movable clamp 132 is driven to move to reduce the gap 130, and then the jaw 13 clamps the corresponding position of the cable tie. Under the continued rotation of the actuating rod 14, the wire reel will be driven to rotate, thereby achieving the knotting of the cable tie.

[0059] like Figure 6 As shown, the cutting mechanism 04 is used to cut the cable tie. Along the conveying direction of the cable tie, the cutting mechanism 04 is located between the conveying mechanism 02 and the wire feeder 03. Figure 6 and Figure 7As shown, the aforementioned cutting mechanism 04 includes a fixed seat 4, a knife seat 41, a cutter 42, a third connecting rod 43, a third elastic member, a fourth connecting rod 45 and a push rod 46. The fixed seat 4 is arranged on the left side of the bracket 20, and an installation space for accommodating the active roller 211, the driven roller 221, the first gear 212 and the intermediate gear 231 is formed between the fixed seat 4 and the mounting seat 011. The knife seat 41 has an accommodating hole 410 inside, and a notch 411 connected to the accommodating hole 410 is formed on the outer peripheral wall of the knife seat 41, and the knife seat 41 has an extending arm 412 extending upward. As shown in FIG. Figure 3 As shown, the aforementioned cutter 42 is installed in the receiving hole 410 of the knife seat 41, and has a through hole 420 connected to the notch 411, and the notch 411 and the through hole 420 form a passage for the cable tie to pass through. The third connecting rod 43 is arranged along the front-to-back direction, and the front end of the third connecting rod 43 is rotatably connected to the extension arm 412 of the knife seat 41; the third elastic member is a third spring 44 located behind the third connecting rod 43, and the front end of the third spring 44 is connected to the rear end of the third connecting rod 43, as shown in FIG. Fig.13 As shown, the rear end of the third spring 44 is connected to the fixed seat 4, and the third connecting rod 43 always has a tendency to move forward in the energy storage state. The above-mentioned mounting shaft 23 is mounted on the fixed seat 4, and the fourth connecting rod 45 is rotatably arranged on the mounting shaft 23 near the middle position, and the upper end of the fourth connecting rod 45 is rotatably connected to the third connecting rod 43 near the middle. The top rod 46 is mounted on the left end of the transmission shaft 6, and the lower end of the fourth connecting rod 45 is located on the rotation path of the free end of the top rod 46. In this way, the lower end of the fourth connecting rod 45 moves forward under the intermittent drive of the top rod 46, and the upper end of the fourth connecting rod 45 moves backward, thereby driving the knife seat 41 to move backward to cut the cable tie. The free end of the cable tie on the material roller 91 passes through the conveying channel between the active roller and the driven roller of the conveying mechanism 02, the opening 420 of the cutter 42, the gap 130 of the upper clamping jaw 13, the arc groove 31 of the wire feeding piece 03 and the gap 130 of the lower clamping jaw 13 in sequence. The cutter 42 cuts the cable tie, and then the clamping jaw 13 clamps the corresponding position of the cable tie, and then the cable tie is knotted under the rotation of the reel 01.

[0060] The working process of the above strapping machine is as follows:

[0061] When the motor 51 rotates forward, the first bevel gear 511 thereon is driven to rotate. Since the second bevel gear 61 is meshed with the first bevel gear 511, and the third bevel gear 81 is meshed with the second bevel gear 61, at this time, the second bevel gear 61 and the third bevel gear 81 are both rotated. The third bevel gear 81 is installed on the first transmission rod 8, and under the action of the second one-way bearing 83, the first transmission rod 8 cannot drive the actuating rod 14 to rotate, that is, the winding device 01 does not work; and when the first one-way bearing 83 is in motion, the first transmission rod 8 cannot drive the actuating rod 14 to rotate. Under the action of the bearing 65, the transmission shaft 6 rotates, and during the rotation of the transmission shaft 6, the conveying mechanism 02 is driven to work. The conveying mechanism 02 drives the cable tie to move toward the cutting mechanism, and passes through the opening 420 of the cutter 42 of the cutting mechanism 04, the gap 130 of the upper clamping jaw 13, and the arc groove 31 of the wire feeding member 03 in sequence. Then, driven by the second transmission component 07, the wire feeding member 03 is driven to rotate downward and the cable tie is sent to the gap 130 of the lower clamping jaw 13. The cutting mechanism cuts the cable tie into sections to complete the wire feeding process.

[0062] When the motor 51 rotates in the opposite direction, it drives the first bevel gear 511 thereon to rotate. Since the second bevel gear 61 and the first bevel gear 511 are meshed, and the third bevel gear 81 is meshed with the second bevel gear 61, at this time, the second bevel gear 61 and the third bevel gear 81 both rotate, and under the action of the first one-way bearing 65, the transmission shaft 6 cannot rotate; since the third bevel gear 81 is installed on the first transmission rod 8, and under the action of the second one-way bearing 83, the first transmission rod 8 drives the actuating rod 14 to rotate, first driving the movable clamping plate 132 to move and reduce the gap 130, and then making the clamping claw 13 clamp the corresponding position of the cable tie, and under the continued rotation of the actuating rod 14, it will drive the wire reel 01 to rotate as a whole, thereby completing the knotting of the cable tie.

[0063] After completing the reverse knotting action of the motor 51, the motor 51 rotates forward, and then drives the transmission gear 62 to rotate. At this time, the protrusion 621 on the transmission gear 62 rotates with the transmission gear 62 to push the lower end of the first connecting rod 71 to move forward, and pull the second connecting rod 72 to move backward, thereby achieving the purpose of lifting the wire feeding component 03 upward, and in this process, the wire feeding action will also continue synchronously to transport the cable tie toward the direction of the wire reel.
