A one-way cable tie entry mechanism 3 with a cable tie passage 30 is installed at the tail of the cable tie cylinder 2, and a cable tie loosening mechanism 4 with a cable tie passage 40 is installed at the end of the push rod 21 of the cable tie cylinder 2, and The cable tie outlet end of the cable tie outlet channel 40 of the cable tie release mechanism 4 is connected with a rigid cable tie outlet tube 5 . In this embodiment, the installation base 1 is T-shaped, and the tie-feeding cylinder 2 is fixed horizontally on one end of the installation base 1. The length of the installation base 1 is slightly longer than the maximum stroke of the push rod 21 of the tie-feeding cylinder 2. .

Generally speaking, the one-way cable tie feeding mechanism 3 in the utility model plays the role of the one-way cable tie feeding, that is, the cable tie cannot be retracted after passing through the one-way cable tie mechanism; The cable tie loosening mechanism 4 installed at the end presses the cable tie to provide tension when the push rod 21 is pushed forward, so that the cable tie is sent out into the rigid cable tie tube 5, and when the push rod 21 returns , then loosen the cable tie, so that the cable tie will not be subjected to reverse pulling force and stop moving, and because the push rod 21 drives the cable tie release mechanism 4 and the rigid cable tie tube 5 to move in the opposite direction, and then the cable tie is exposed on the Rigidity comes out of the cable tie tube 5, and the exposed cable tie is just located on the binding cable tie station of the winding and binding machine, and then the cable tie is cut off by the cutting mechanism, that is, the process of sending the cable tie once is completed, so that the cycle operation can be continuously sent tie.

Specifically, as shown in FIG. 3 , the one-way cable tie feeding mechanism 3 has a cable tie seat 31, and a cable tie channel 30 is arranged in the cable tie seat 31, and the cable tie channel 30 The upper and lower sides are respectively provided with an upper cavity 301 and a lower cavity 302 connected thereto; a one-way bearing 32 is installed in the lower cavity 302, and the upper surface of the one-way bearing 32 enters the range of the cable tie channel 30 A pinch wheel seat 33 is pivotally connected in the upper chamber 301, and a pinch wheel 34 opposite to the one-way bearing 32 is mounted on the pinch wheel seat 33, and in the upper chamber 301, the pinch wheel seat The top of 33 is also provided with pressure regulating spring 35 and the pressure regulating screw rod 36 that passes in and out of cable tie seat 31.

The working principle of the one-way cable tie is: before starting to wear the cable tie, the pressure regulating screw 36 is unscrewed so that the pressure regulating spring 35 does not exert pressure on the pressure roller seat 33, and the pressure roller seat 33 and the pressure rollers on it 34 is in a state that can be easily loosened, and then the cable tie is passed through the cable tie channel 30, so that the cable tie is located between the pressure roller 34 and the one-way bearing 32 and passed into the cable tie seat 31; The screw rod 36 is properly tightened according to the specifications of the cable tie, so that the pressure regulating spring 35 exerts a certain pressure on the pressure roller seat 33, that is, the pressure roller 34 exerts a certain pressure on the cable tie (a small pressure is enough) so that the cable tie is pressed against the pressure roller seat 33. Between the wheel 35 and the one-way bearing 32; since the one-way bearing 32 in this embodiment can only rotate clockwise as shown in the figure, when the cable tie is pulled forward (that is, to the right in the figure), as long as the tie The tension that the belt is subjected to can overcome the frictional force produced by the pressure of the pressure roller 34, and the cable tie can be pulled forward; and conversely, because the one-way bearing 32 cannot rotate counterclockwise, even if the cable tie is subjected to a leftward pulling force , it is also impossible to be easily pulled in the opposite direction, but the cable tie in the utility model will not be subjected to reverse pulling force, only the push rod 21 of the cable tie cylinder 2, the cable tie release mechanism 4, and the rigid cable tie tube 5 When moving in the reverse direction, there will be a small friction force on the cable tie. This friction force is so small that it is impossible to drive the cable tie to move to the left together, so as to achieve the effect that the cable tie only moves in one direction.

The outer wheel of the one-way bearing 32 is fixedly equipped with a circular ring 321 with teeth on the outer surface, so that the teeth can be slightly sunk into the plastic surface of the cable tie, thereby further preventing the reverse movement of the cable tie.

A group of cable tie rollers 311 are also provided on the cable tie feeder seat 31, which can reduce the friction of the cable tie feeder, and the cable tie can enter from the upper and lower sides without entering straight from the front, so that the whole roll of cable tie can be Hang above it to reduce the space it takes up.

As shown in FIG. 4 , the tie loosening mechanism 4 has a tie loosening seat 41 connected to the push rod 21 of the tie sending cylinder 2 , and the tie loosening seat 41 is provided with a tie outlet. There is a channel 40, and the upper side of the cable tie channel 40 is sequentially provided with a compression tie block chamber 401 and a piston chamber 402 communicating with it, and the top of the piston chamber 402 communicates with the air pressure pipeline 403; A strap block 42 is pivotally connected to the strap block cavity 401 , and a piston 43 and a piston spring 44 located above the strap block 42 are arranged in the piston cavity 402 .

As shown in FIG. 5 , the principle of loosening and pressing the cable tie by the cable tie loosening mechanism 4 is: in the initial state, the air pressure pipe 403 is not inflated, and does not generate downward pressure on the piston 43 , and the piston 43 is pressed together under the elastic force of the piston spring 44 . The strap block 42 is in a separated state, and the strap block 42 is in a free state. At this time, the strap can be passed through the strap outlet channel 40 and passed out into the rigid strap outlet pipe 5; when the push rod 21 of the strap cylinder 2 is sent When moving forward, the air pressure pipe 403 on the top of the cable tie loosening seat 41 is inflated, and the piston 43 in the piston chamber 402 is driven to press and press the cable tie pressing block 42. The cable tie pressing block 42 tightly presses the cable tie, thereby driving The cable ties move forward together; when the length of the cable tie delivery is reached, the air pressure pipe 403 deflates, so that the pressure of the piston 43 on the cable tie pressing block 42 disappears, and the cable tie pressing block 42 returns to the pivotal free state, which is not necessary for the cable tie. Extra pressure is generated, that is, the cable tie is no longer pulled out; when the push rod 21 of the cable tie delivery cylinder 2 runs in reverse, the cable tie release mechanism 4 and the rigid cable tie tube 5 move in reverse as a whole, and the cable tie It is in a non-moving state and exposed from the rigid cable tie tube 5, so as to realize the purpose of sending the cable tie.

The bottom surface of the cable tie block 42 is provided with a cable tie tooth pattern 421, and the direction of the cable tie tooth pattern 421 is along the moving direction of the cable tie. When the cable tie block 42 moves forward, the cable tie tooth pattern 421 is conducive to the forward thrust of the cable tie block 42 to the cable tie, which helps to transmit power; There is no opposing force on the cable tie.

A magnetic sensor 22 is also provided outside the cylinder body of the tie-feeding cylinder 2 , and the magnetic sensor 22 is electrically connected to a controller that controls the charging and discharging of the air pressure pipe 403 of the tie-releasing mechanism 4 . In this embodiment, the magnetic sensor 22 is installed on the periphery of the cylinder body of the cable tie feeding cylinder 2 by binding, so that its position can be adjusted conveniently. The magnetic sensor 22 is used to sense the stroke of the push rod 21, because the inner end of the push rod 21 is provided with a magnet, and when the inner end of the push rod 21 reaches the position where the magnetic sensor 22 is located , the magnetic sensor 22 will generate an induction signal to the controller that controls the inflation and deflation of the air pressure pipeline 403, and the controller will control the air pressure pipeline 403 to deflate, so that the piston 43 of the cable tie release mechanism 4 and the cable tie pressing block 42 Separate, that is, the cable tie pressing block 42 will loosen the cable tie and no longer compress it. At this time, even if the cable tie loosening mechanism 4 still advances, the cable tie will not advance accordingly. Therefore, as long as the position of the magnetic sensor 22 is adjusted , the length of the cable tie can be controlled each time to meet actual needs; and when the push rod 21 moves in the reverse direction, the magnetic sensor 22 does not work.

A spring pipe 6 is also provided between the one-way cable tie entry mechanism 3 and the cable tie release mechanism 4, and the two ends of the spring pipe 6 are provided with plug joints 61 respectively connected with the cable tie entry passage 30 and the tie exit channel 30 respectively. Connected with channel 40. The reason for setting the spring duct 6 is because there is a long distance between the one-way cable tie mechanism 3 and the cable tie release mechanism 4, and the cable tie can pass through the spring channel 6 to avoid sagging while not affecting the transmission of the cable tie. The end plug joint 61 can be made of plastic material, which can be quickly inserted into the cable tie channel and fixed by friction force, and it is also convenient and quick to wear the cable tie when the spring pipe 6 is shortened.

That is to drive the blade 71 to move downwards to cut off the tie. In the present invention, the position of the blade 71 is at the outer end of the rigid tie pipe 5 when the stroke of the push rod 21 of the tie cylinder 2 is zero in the initial state. , that is, after the rigid cable tie tube 5 sends out the cable tie and returns to its original position, the blade 71 cuts off the cable tie under the drive of the cutter bar 73 . The cutter mechanism 7 of the utility model is positioned at the rear side of the installation base frame 1 as a whole, and only the blade is positioned at the front, so the installation space is greatly saved.
