Description

Technical Field

[0001] The invention relates to the technical field of cable packaging machinery, in particular to a handheld cable tie binding machine. Background Art

[0002] Electronic production plants often have a large number of wire harnesses and cable components that need to be packaged. Generally, they need to be bundled into bundles first, and then put into sealed bags or anti-static bags and other final packaging. If the cable tie bundling is all done manually, it will be time-consuming and labor-intensive, and requires automated machines.

[0003] In the prior art, cable tie machines are often semi-automatic platform machines or handheld machines, and the common problems are low adaptability to the workpieces to be tied and complex structures. Generally, cable tie machines are only for wire harnesses with small size changes. When the diameter changes greatly, the cable tie machine model needs to be replaced. In addition, there are multiple actuators in the cable tie machine, and the execution of the action components has a sequence and timing. In the prior art, cable tie machines often need to be equipped with multiple sensors to detect the arrival signals of different components, and control subsequent actions through a microcomputer, which greatly increases the control cost and complexity.

[0004] In addition, in the prior art, the cable ties are conveyed to the handheld gun at a very fast speed and often fly out of the trough. Therefore, the handheld gun does not receive the cable ties during this operation cycle, and the handheld gun does not complete the bundling operation and needs to restart the operation cycle. The operator needs to manually judge whether the bundling is completed, which affects efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a method to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A hand-held cable tie bundling machine comprises a hand-held gun, a machine platform, a feed tray, a control console, a wiring panel and a forward push assembly. The feed tray is placed on the machine platform, and the control console and the forward push assembly are respectively installed on the machine platform. The forward push assembly is located next to the feed tray. The wiring panel is connected to the hand-held gun. The wiring panel supplies the hand-held gun with cable ties for bundling workpieces as well as an air source and a power source for operation. The forward push assembly pushes the cable ties conveyed by the feed tray into the wiring panel in sequence; a cable tie limiting structure is arranged in the forward push assembly.

[0007] A large number of cable ties to be used are placed in the feeding tray. After being put in, the cable ties are in a disorderly manner. The feeding tray uses vibration and other methods to organize the cable ties into a specific identical posture for spiral conveying. They are fed into the forward push component one by one at the output port. The forward push component feeds the cable ties of uniform posture into the wiring panel one by one according to the feeding rhythm set by the control console. Subsequently, the cable ties are transported by pneumatic force and supplied to the handheld gun. The handheld gun uses the cable ties to bundle the workpieces to complete an operation cycle. Due to the high displacement speed of the cable ties at the forward push component, if there is no limit structure, it is easy to fly out of the conveying trough, so a limit structure is used to block the cable ties to prevent operation errors.

[0008] The handheld gun includes an upper shell, a lower shell, an inner support plate, a head cover, a trigger claw assembly, a top claw assembly, a traction assembly, and a cutting assembly. The upper shell and the lower shell are connected to form an inner cavity and the inner support plate is fixed in the inner cavity. A wire entry hole and a cable tie path are provided at the tail of the upper shell and the lower shell after they are connected to each other. The head cover is fixed on at least two of the upper shell, the lower shell, and the inner support plate. The head cover is located at one end away from the wire entry hole. The trigger claw assembly is installed on the inner support plate and extends out of the upper shell and the lower shell. The top claw assembly is installed on the inner support plate and the head cover. When the trigger claw assembly and the top claw assembly are in action, they cooperate with the side surface of the end of the inner support plate to form a closed annular area. A channel is set in the inner support plate to allow the cable tie to pass through, and the channel connects the cable tie channel and the annular area. A hole is set on the side of the inner support plate to allow the tail of the cable tie to pass through. A wire hole is also set on the side wall of the head cover. The traction assembly is installed on the inner support plate and the head cover. The traction assembly pulls the tail of the cable tie passing through the wire hole to tighten it. The cutting assembly is installed on the inner support plate. The cutting assembly is used to cut off the excess length of the cable tie passing through the wire hole. The traction assembly and the cutting assembly adopt delay control. After the trigger claw assembly is actuated, the traction assembly and the cutting assembly start and stop after the set time respectively.

[0009] The cable tie is blown in from the cable tie channel, and after the trigger claw assembly is pressed, the trigger claw assembly and the top claw assembly cooperate with the inner support plate to close in an annular manner, and the cable tie moves forward with the tail of the tie in front without a ring, and the tail of the cable tie turns around the annular closed line, and the head of the cable tie with the ring is blocked and limited on one side of the wire hole. The tail of the cable tie moves forward at a high speed, and then the tail completes a full circle turn and passes through the cable tie head and into the wire hole. The traction assembly bites the tail of the cable tie and pulls to tighten the cable tie until it is completely tied up The workpiece to be tied in the annular closed space has an expected value range for the time taken for this action according to the size of the handheld gun. The action start timing of the cutting component is set according to the maximum value of the expected range, and the excess length of the cable tie after bundling is cut off. Then the trigger claw assembly is released, the workpiece is detached from the working area, and the staff performs the next action.

[0010] The trigger claw assembly includes a tongue, a tongue seat, and a lower claw. The tongue seat is fixedly mounted on the inner support plate. The middle position of the tongue is hinged on the tongue seat. One end of the tongue extends out of the upper shell and the lower shell. One end of the lower claw is hinged on the inner support plate. The other end of the lower claw extends out of the upper shell and the lower shell. The end of the lower claw extending from the upper shell faces the top claw assembly. The other end of the tongue is hinged to the middle position of the lower claw. After the tongue is buckled, the lower claw rotates toward the top claw assembly. A motion sensor is arranged on the side of the tongue seat facing the buckle tongue. The motion sensor identifies the distance of the buckle tongue and transmits it to the pulling component and the cutting component as an execution signal.

[0011] The workpiece to be bundled is fed into the lower claw and top claw assembly, and the buckle tongue is buckled down as an action signal when the hand-held gun operator operates. The lower claw is first lifted up and closed with the top claw assembly, and a cable tie is blown into the cable tie channel. The action of buckling the buckle tongue down obtains action signals through photoelectric sensors, physical buttons, etc., which all belong to the concept of motion sensors. After the air-blown cable tie binds the workpiece, the tail reaches the traction assembly and is pulled and tightened. It is cut off by the cutting assembly after a delay of, for example, one second, and then the buckle tongue is released, the lower claw opens, and the bundled workpiece is released.

[0012] The top claw assembly includes a lifting drive, a connection block, a guide rod, and an upper claw. The shell part of the lifting drive is installed on the inner support plate. The telescopic end of the lifting drive is connected to the guide rod through the connection block. The guide rod is slidably installed in the head cover. The sliding direction of the guide rod is parallel to the length direction of the upper shell. A top claw hole is arranged on the end of the head cover away from the upper shell. The upper claw is hinged in the top claw hole. The guide rod is also hinged to the upper claw. The inner surfaces of the upper claw and the lower claw are provided with an arc groove for accommodating the passage of the cable tie. The inner groove of the end of the upper claw close to the lower claw protrudes a section and is arc-shapedly mortised with the groove on the inner surface of the lower claw. The lifting drive is also electrically connected to the motion sensor, and the ejection action of the lifting drive is performed before the pulling component performs the action.

[0013] The top jaw assembly also moves. After the lower jaw is lifted and the end of the upper jaw is closed, the upper jaw will be further driven by the lifting drive to rotate a certain angle around the upper jaw hinge installation point, so that the workpiece between the upper and lower jaws can be completely bitten, and the cable tie will rotate in a circular arc in the groove on the inner surface of the upper and lower jaws, surround the workpiece, and then be pulled and tightened.

[0014] A waist round head is arranged at the end portion of the guide rod connected with the upper claw, and a cylinder is arranged on the upper claw and penetrates into the waist round head.

[0015] When the guide rod moves toward the upper claw, it pushes the upper claw to close. If the hinge between the guide rod and the upper claw is a conventional cylindrical pin hinge, the hinge point needs to move in an arc to prevent interference. However, the sliding installation space where the guide rod is located is limited, and it is not easy to swing while sliding. Therefore, a waist-round head is set at its head to compensate for the movement perpendicular to the length direction of the guide rod during the hinge.

[0016] The traction assembly includes a machine base plate, a motor, a transition gear, and an intermeshing gear set. The machine base plate is fixed to at least one of the inner support plate, the upper shell, and the lower shell. The motor is installed on the machine base plate. The proximal bearing hole and the distal bearing hole are arranged side by side on the head cover. The intermeshing gear set includes two rotating bodies that are respectively rotatably installed in the proximal bearing hole and the distal bearing hole. The intermeshing gear set has a pair of externally meshing gears at the shaft end. Teeth are arranged in the middle position of the intermeshing gear set. The transition gear is rotatably installed on the machine base plate. The transition gear is transmission-connected to the output end of the motor. The transition gear also meshes with one of the intermeshing gear sets for transmission.

[0017] The motor is driven by the transition gear, and the motor can be installed far away from the meshing gear set, which is convenient for counterweight design. Ideally, the center of gravity of the whole machine should be slightly inside the operator's thumb when holding it. At this time, the grip feels better and it is not easy to slip out of the hand. If the motor is directly set to the end of a rotating body shaft in the meshing gear set, it is easy to feel like holding an axe, which is inconvenient to use. When the motor rotates, the transition gear is driven, and the meshing gear set meshes and rotates. The middle position is the position where the tail of the cable tie passes. At this time, the teeth of the middle section of the meshing gear set bite the cable tie and pull it in the tightening direction. At the end of the pulling, the cutting component moves to cut off the excess length.

[0018] The distal bearing hole is farther away from the motor than the proximal bearing hole, and the distal bearing hole is oval in shape.

[0019] The rotating body farther away from the motor in the meshing gear set is installed in a floating manner. The floating clearance is the thickness of the cable tie. The slight floating clearance of the gear will not cause the gear at the shaft end to be unable to transmit.

[0020] The cutting assembly includes a cutting drive, an extension rod, and a cutting rod. The cutting drive shell part is installed on the inner support plate, the extension rod and the cutting rod are connected, one end of the extension rod is connected to the telescopic end of the cutting drive, the end of the cutting rod away from the cutting drive is adjacent to the wire hole, and a cutting groove is arranged in the head cover. The cutting groove is located on the side of the wire hole away from the upper claw, and the cutting rod is slidably installed along the cutting groove.

[0021] The tail of the wound cable tie is passed through the wire hole and the meshing gear set in turn, and is cut off by the head of the cutting rod driven by the cutting drive on one side of the wire hole. The waste cable tie is continuously pulled backward by the meshing gear set and thrown out of the handheld gun.

[0022] The lifting drive and cutting drive are air-driven cylinders.

[0023] The weight of the air-driven cylinder is smaller than that of the electric-driven cylinder, and the air supply is convenient. The wire entering the wire inlet hole can be divided into two routes for lifting drive and cutting drive to supply compressed gas. A solenoid valve can be set on the air supply pipeline to control the action timing of the lifting drive and cutting drive.

[0024] The handheld gun also includes a waste nozzle, which is installed on the side of the head cover away from the upper claw, and the waste nozzle is directly opposite to the meshing clearance of the meshing gear set.

[0025] The waste nozzle is used as the discharge outlet for the cut-off cable tie tails. It can be connected to a pipeline for collection to prevent clutter around.

[0026] The forward push assembly includes a bottom plate, a side plate, a cylinder, a connecting block, a forward push block, a belt outlet nozzle, and a cover plate. The bottom plate is fixed on the machine platform. A side plate is arranged on the side of the bottom plate away from the feeding tray. The side plate is provided with a guide rail and a connecting block is slidably installed. The forward push block is also slidably installed on the side plate. The forward push block is fixed to the connecting block. The outer shell of the cylinder is connected to the side plate. The telescopic end of the cylinder is transmitted to the connecting block. The belt outlet nozzle is arranged on the end of the bottom plate away from the forward push block. The upper surface of the bottom plate is provided with a tape feeding groove and a tape outlet groove which are perpendicular to each other. The two ends of the tape outlet groove are connected to the front push block and the tape outlet nozzle respectively. The tape feeding groove is located in the direction of the connection line between the side plate and the feeding tray. One end of the tape feeding groove is connected to the tape outlet groove. A limiting inclined surface is provided on the tape outlet groove at the position where it is connected to the tape feeding groove. The cover plate is installed on the bottom plate and covers the tape feeding groove. The front push block includes a push rod, a push plate, a pressure block, and an elastic body. The back of the push rod is fixed to the connecting block. A push plate is set at the front end of the push rod facing the tape outlet mouth. The pressure block is rotatably set on the push plate. The hinge axis of the push plate and the pressure block is parallel to the length direction of the tape feeding groove. An elastic body is padded between the pressure block and the push plate. The thrust direction of the elastic body is to press the pressure block into the tape outlet groove.

[0027] The head of the cable tie is conveyed from the feed tray into the tape feeding slot, and the tail of the cable tie can float outside the slot. The head of the cable tie enters the tape outlet slot at the end of the tape feeding slot, and the pressure block presses the head of the cable tie. The head of the cable tie can only be stationary here due to the obstruction of the limiting slope, preventing the cable tie sent from the tape feeding slot from escaping from the tape outlet slot due to excessive speed. When a new cable tie needs to be supplied to the handheld gun, the cylinder extends, and the front push block moves forward along the tape outlet slot together, and the push rod pushes the cable tie forward. When the head of the cable tie passes through the limiting slope, the pressure block is squeezed upward. Due to the presence of the elastic body, the pressure block has a continuous downward pressure, which keeps the head of the cable tie in contact with the tape outlet slot until it enters the wiring panel from the tape outlet mouth to supply the handheld gun.

[0028] The binding machine also includes a cover, which is rotatably mounted on the machine platform and covers the front push assembly when the cover is closed. When the cover is turned up, it can cover the front push assembly to prevent debris from entering the cable tie conveying area during operation and causing an impact.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention engages the workpiece to be bundled through the arc-shaped upper claw and the lower claw. After the lower claw is lifted to start the bundling action, the upper claw also moves downward to fully enclose the workpiece, the cable tie slides in the inner surface grooves of the upper and lower claws and bundles the workpiece, the traction component pulls the cable tie tail to tighten it, and the cutter rod cuts off the excess length, and all the actions after pressing the buckle tongue are delayed and completed automatically, without the need to judge the internal position state, saving the setting of sensors and the complexity of signal control; the engaging gear set has a fine-tunable installation gap to accommodate the entry of the cable tie tail, and is not prone to slipping off or getting stuck.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A hand-held cable tie bundling machine includes a hand-held gun, a machine platform 81, a feed tray 82, a control console 83, a wiring panel 85 and a forward push component 9. The feed tray 82 is placed on the machine platform 81, and the control console 83 and the forward push component 9 are respectively installed on the machine platform 81. The forward push component 9 is located next to the feed tray 82. The wiring panel 85 is connected to the hand-held gun. The wiring panel 85 supplies the hand-held gun with cable ties for bundling workpieces as well as air source and power source for operation. The forward push component 9 pushes the cable ties delivered from the feed tray 82 into the wiring panel 85 in sequence; a cable tie limiting structure is arranged in the forward push component 9.

[0033] like Figure 1As shown, a large number of cable ties to be used are placed in the feeding tray 82. After being placed in, the cable ties are in a disorderly manner. The feeding tray 82 uses vibration and other methods to arrange the cable ties into a specific identical posture for spiral conveying, and feeds them one by one into the forward push component 9 at the output port. The forward push component 9 feeds the cable ties of uniform posture into the wiring panel 85 one by one according to the feeding rhythm set by the control console 83. Subsequently, the cable ties are transported by pneumatic force to supply the handheld gun, which uses the cable ties to bundle the workpieces to complete an operation cycle. Since the cable ties at the forward push component 9 have a large displacement speed, if there is no limit structure, they are easy to fly out of the conveying trough, so the limit structure is used to block the cable ties to prevent operation errors.

[0034] The handheld gun includes an upper shell 11, a lower shell 12, an inner support plate 2, a head cover 3, a trigger claw assembly 4, a top claw assembly 5, a traction assembly 6, and a cutting assembly 7. The upper shell 11 and the lower shell 12 are connected to form an inner cavity and the inner support plate 2 is fixed in the inner cavity. The tail of the upper shell 11 and the lower shell 12 after being connected to each other is provided with a wire entry hole 13 and a cable tie path 14. The head cover 3 is fixed to at least two of the upper shell 11, the lower shell 12, and the inner support plate 2. The head cover 3 is located at one end away from the wire entry hole 13. The trigger claw assembly 4 is installed on the inner support plate 2 and extends out of the upper shell 11 and the lower shell 12. The top claw assembly 5 is installed On the inner support plate 2 and the head cover 3, the trigger claw assembly 4 and the top claw assembly 5 cooperate with the side surface of the end of the inner support plate 2 to form a closed annular area when in action. A channel allowing the cable tie to pass through is set in the inner support plate 2, and the channel connects the cable tie channel 14 and the annular area. A hole allowing the tail of the cable tie to pass through is set on the side of the inner support plate 2. A wire hole 33 is also set on the side wall of the head cover 3. The traction assembly 6 is installed on the inner support plate 2 and the head cover 3. The traction assembly 6 pulls the tail of the cable tie passing through the wire hole 33 to tighten it. The cutting assembly 7 is installed on the inner support plate 2. The cutting assembly 7 is used to cut off the excess length of the cable tie passing through the wire hole 33. The traction assembly 6 and the cutting assembly 7 adopt delay control. After the trigger claw assembly 4 is actuated, the traction assembly 6 and the cutting assembly 7 are started and stopped after a set time respectively.

[0035] like Figure 2 , 3As shown in , 7, the cable tie is blown in from the cable tie channel 14, and after the trigger claw assembly 4 is pressed, the trigger claw assembly 4 and the top claw assembly 5 cooperate with the inner support plate 2 to close in an annular manner, and the cable tie moves forward with the tail of the tie in front without a ring, and the tail of the cable tie turns around the annular closed line, and the head of the cable tie with the ring is blocked and limited on one side of the wire hole 33. After the tail of the cable tie completes a full circle turn in a forward high-speed state, it passes through the cable tie head and penetrates into the wire hole 33, and the traction assembly 6 bites the tail of the cable tie and pulls to tighten the cable tie until the workpiece to be tied in the annular closed space is completely tied up. The time spent on this action has an expected value range according to the size of the handheld gun, and the action start timing of the cutting assembly 7 is set according to the maximum value of the expected range, and the excess length of the cable tie after binding is cut off, and then the trigger claw assembly 4 is released, the workpiece is detached from the working area, and the staff performs the next action.

[0036] The trigger claw assembly 4 includes a buckle tongue 41, a tongue seat 42, and a lower claw 43. The tongue seat 42 is fixedly mounted on the inner support plate 2. The middle position of the buckle tongue 41 is hinged on the tongue seat 42. One end of the buckle tongue 41 extends out of the upper shell 11 and the lower shell 12. One end of the lower claw 43 is hinged on the inner support plate 2. The other end of the lower claw 43 extends out of the upper shell 11 and the lower shell 12. The end of the lower claw 43 extending from the upper shell 11 is toward the top claw assembly 5. The other end of the buckle tongue 41 is hinged to the middle position of the lower claw 43. After the buckle tongue 41 is buckled, the lower claw 43 rotates toward the top claw assembly 5. A motion sensor is provided on the side of the tongue seat 42 facing the buckle tongue 41 . The motion sensor identifies the distance of the buckle tongue 41 and transmits it to the pulling component 6 and the cutting component 7 as an execution signal.

[0037] like Figures 2~4 As shown, the workpiece to be bundled is fed into the lower claw 43 and the top claw assembly 5, and the buckle tongue 41 is buckled down as an action signal when the hand-held gun operator operates. The lower claw 43 is first lifted up and closed with the top claw assembly 5, and a cable tie is blown into the cable tie channel 14. The action of buckling the buckle tongue 41 obtains an action signal through photoelectric sensors, physical buttons, etc., which all belong to the concept of action sensors. After the air-blown cable tie is tied up with the workpiece, the tail end reaches the traction assembly 6 and is pulled and tightened. It is cut off by the cutting assembly 7 after a delay of, for example, one second, and then the buckle tongue 41 is released, the lower claw 43 opens, and the bundled workpiece is released.

[0038] The top claw assembly 5 includes a lifting drive 51, a connecting block 52, a guide rod 53, and an upper claw 54. The shell part of the lifting drive 51 is installed on the inner support plate 2. The telescopic end of the lifting drive 51 is connected to the guide rod 53 through the connecting block 52. The guide rod 53 is slidably installed in the head cover 3. The sliding direction of the guide rod 53 is parallel to the length direction of the upper shell 11. A top claw hole 35 is set on the end of the head cover 3 away from the upper shell 11. The upper claw 54 is hinged in the top claw hole 35. The guide rod 53 is also hinged to the upper claw 54. The upper claw 54 and the inner surface of the lower claw 43 are provided with an arc groove for accommodating the passage of the cable tie. The upper claw 54 protrudes a section of the inner groove near the end of the lower claw 43 and is arc-shaped with the inner surface groove of the lower claw 43. The lifting drive 51 is also electrically connected to the motion sensor, and the ejection action of the lifting drive 51 is performed before the pulling component 6 performs the action.

[0039] like Figures 3 to 7 As shown, the top jaw assembly 5 also moves. After the lower jaw 43 is lifted and the end of the upper jaw 54 is closed, the upper jaw 54 will be further pushed by the lifting drive 51 and rotate around the hinged installation point of the upper jaw 54 for a certain angle, so that the workpiece between the upper jaw 54 and the lower jaw 43 can be completely bitten, and the cable tie rotates in a circular arc in the groove on the inner surface of the upper and lower jaws to surround the workpiece, and then is pulled and tightened.

[0040] A round head 531 is disposed at the end of the guide rod 53 connected to the upper claw 54 , and a cylinder is disposed on the upper claw 54 and penetrates into the round head 531 .

[0041] like Figure 4 , 7 As shown, when the guide rod 53 moves toward the upper claw 54, it pushes the upper claw 54 to close. If the hinge between the guide rod 53 and the upper claw 54 is a conventional cylindrical pin hinge, the hinge point needs to move in an arc to prevent interference. However, the sliding installation space where the guide rod 53 is located is limited, and it is not easy to swing while sliding. Therefore, a waist round head 531 is set at its head to compensate for the movement perpendicular to the length direction of the guide rod 53 during the hinge.

[0042] The traction assembly 6 includes a machine base plate 61, a motor 62, a transition gear 63, and an engaging gear set 64. The machine base plate 61 is fixed to at least one of the inner support plate 2, the upper shell 11, and the lower shell 12. The motor 62 is installed on the machine base plate 61. The proximal bearing hole 31 and the distal bearing hole 32 are arranged side by side on the head cover 3. The engaging gear set 64 includes two rotating bodies that are rotatably installed in the proximal bearing hole 31 and the distal bearing hole 32 respectively. The engaging gear set 64 has a pair of externally meshing gears at the shaft end. Teeth are arranged in the middle position of the engaging gear set 64. The transition gear 63 is rotatably installed on the machine base plate 61. The transition gear 63 is transmission-connected to the output end of the motor 62. The transition gear 63 also meshes with one of the meshing gear sets 64 for transmission.

[0043] like Figure 4 ,7 As shown, the motor 62 is driven by the transition gear 63. The installation position of the motor 62 can be far away from the meshing gear set 64, which is convenient for counterweight design. In an ideal state, the center of gravity of the whole machine should be slightly inside the operator's thumb when holding it. At this time, the grip feels better and it is not easy to slip out of the hand. If the motor is directly set to the end of a rotating body shaft in the meshing gear set 64, it is easy to feel like holding an axe, which is inconvenient to use. When the motor 62 rotates, the transition gear 63 is driven, and the meshing gear set 64 meshes and rotates. The middle position is the position where the tail of the cable tie passes. At this time, the teeth of the middle section of the meshing gear set 64 bite the cable tie and pull it in the tightening direction. At the end of the pulling, the cutting component 7 moves to cut off the excess length.

[0044] The distal bearing hole 32 is farther away from the motor 62 than the proximal bearing hole 31 , and the distal bearing hole 32 is in an oval shape.

[0045] like Figure 4 , 7 As shown, the rotating body in the meshing gear set 64 which is farther away from the motor 62 is installed in a floating manner, and the floating clearance is the thickness of the cable tie. The slight floating clearance of the gear will not cause the gear at the shaft end to be unable to transmit.

[0046] The cutting assembly 7 includes a cutting drive 71, an extension rod 72, and a cutting rod 73. The shell portion of the cutting drive 71 is installed on the inner support plate 2, and the extension rod 72 and the cutting rod 73 are connected. One end of the extension rod 72 is connected to the telescopic end of the cutting drive 71. The end of the cutting rod 73 away from the cutting drive 71 is adjacent to the wire hole 33. A cutting groove 34 is set in the head cover 3. The cutting groove 34 is located on the side of the wire hole 33 away from the upper claw 54, and the cutting rod 73 is slidably installed along the cutting groove 34.

[0047] like Figures 4 to 7 As shown, the tail of the wound cable tie passes through the wire hole 33 and the meshing gear set 64 in sequence, and is cut off at one side of the wire hole 33 by the head of the cutting rod 73 pushed by the cutting drive 71, and the waste cable tie is continued to be pulled backward by the meshing gear set 64 and thrown out of the handheld gun.

[0048] The lifting drive 51 and the cutting drive 71 are air-driven cylinders.

[0049] The weight of the air-driven cylinder is relatively small compared to the electric-driven one, and the air supply is convenient. The wire entering the wire inlet hole 13 can be divided into two routes to supply compressed gas to the lifting drive 51 and the cutting drive 71. An electromagnetic valve can be set on the air supply pipeline to control the action timing of the lifting drive 51 and the cutting drive 71.

[0050] The handheld gun further comprises a waste nozzle 15 , which is mounted on a side of the head cover 3 away from the upper claw 54 , and the waste nozzle 15 is directly opposite to the meshing clearance of the meshing gear set 64 .

[0051] The waste nozzle 15 is used as a discharge outlet for the cut-off cable tie tails, and can be connected to a pipeline for collection to prevent clutter around.

[0052] The forward push assembly 9 includes a bottom plate 91, a side plate 92, a cylinder 93, a connecting block 94, a forward push block 95, a belt outlet nozzle 96, and a cover plate 97. The bottom plate 91 is fixed on the machine table 81. The side plate 92 is provided on the side of the bottom plate 91 away from the feeding tray 82. The side plate 92 has a guide rail and a connecting block 94 is slidably installed. The forward push block 95 is also slidably installed on the side plate 92. The forward push block 95 is fixed to the connecting block 94. The outer shell of the cylinder 93 is connected to the side plate 92. The telescopic end of the cylinder 93 is transmitted to the connecting block 94. The belt outlet nozzle 96 is provided on the end of the bottom plate 91 away from the forward push block 95. A tape feeding groove 911 and a tape outlet groove 912 are arranged perpendicular to each other on the upper surface of the bottom plate 91. The two ends of the tape outlet groove 912 are connected to the front push block 95 and the tape outlet nozzle 96 respectively. The tape feeding groove 911 is located in the direction of the line connecting the side plate 92 and the feeding tray 82. One end of the tape feeding groove 911 is connected to the tape outlet groove 912. A limiting inclined surface 913 is arranged on the tape outlet groove 912 at the position connected to the tape feeding groove 911. The cover plate 97 is installed on the base plate 91 and covers the tape feeding groove 911. The front push block 95 includes a push rod 951, a push plate 952, a pressure block 953, and an elastic body 954. The back of the push rod 951 is fixed to the connecting block 94. A push plate 952 is set at the front end of the push rod 951 toward the tape outlet mouth 96. The pressure block 953 is rotatably set on the push plate 952. The hinge axis of the push plate 952 and the pressure block 953 is parallel to the length direction of the tape feeding groove 911. An elastic body 954 is padded between the pressure block 953 and the push plate 952. The thrust direction of the elastic body 954 is to press the pressure block 953 into the tape outlet groove 912.

[0053] like Figures 8-10 As shown, the head of the cable tie is transported from the feeding tray 82 into the tape feeding slot 911, and the tail of the cable tie can float outside the slot. The head of the cable tie enters the tape outlet slot 912 at the end of the tape feeding slot 911, and the pressing block 953 presses the head of the cable tie. The head of the cable tie can only be stationary here due to the obstruction of the limiting inclined surface 913, preventing the cable tie sent from the tape feeding slot 911 from escaping from the tape outlet slot 912 due to excessive speed. When a new cable tie needs to be supplied to the handheld gun, the cylinder 93 extends, and the front push block 95 moves forward along the tape outlet slot 912 together. The push rod 951 pushes the cable tie forward. When the head of the cable tie passes through the limiting inclined surface 913, the pressing block 953 is squeezed upward. The pressing block 953 has a continuous downward pressure due to the presence of the elastic body 954, which keeps the head of the cable tie in contact with the tape outlet slot 912 until it enters the wiring panel 85 from the tape outlet mouth 96 to supply the handheld gun.

[0054] The binding machine further comprises a cover 84, which is rotatably mounted on the machine platform 81, and covers the forward push assembly 9 when the cover 84 is closed. Figure 1As shown, the cover shell 84 is in an open state, and can cover the forward push assembly 9 after being turned up to prevent debris from entering the cable tie conveying area during operation and causing an impact.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
