Description

Technical Field

[0001] The present application relates to the technical field of cable tie machines, and in particular to an electric cable tie machine. Background Art

[0002] With the development of intelligent devices, their intelligence is getting higher and higher. In order to ensure the intelligence, the number of wiring harnesses used to transmit various signals is increasing. Therefore, the wiring and routing in intelligent devices is the premise to ensure the normal operation of intelligent devices.

[0003] At present, the wiring on the market usually uses cable ties to bundle several wires together to prevent them from being loosely entangled. The current cable tie bundling operation method is usually that the operator tightens the bundle and then cuts off the excess cable tie with a pliers knife to complete the effect of bundling and fixing the wires.

[0004] With respect to the above-mentioned related technologies, the inventors of the utility model found that after the cable ties are manually tightened, they still need to be cut off one by one with pliers, which leads to low efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides an electric cable tie machine, which has the advantages of automatically tightening and cutting the cable tie, thereby improving production efficiency.

[0006] In order to achieve the above object, the technical solution of the utility model is as follows:

[0007] An electric cable tie machine comprises a housing, wherein a tightening mechanism for tightening the cable tie and a cutting mechanism for cutting the cable tie are arranged in the housing, and a driving mechanism for driving the tightening mechanism and the cutting mechanism to be linked is arranged on the housing;

[0008] The cutting mechanism comprises a knife body rotatably arranged on the housing, and a knife head is arranged at the end of the knife body;

[0009] The tightening mechanism comprises a clamping rod slidably arranged on the housing, and the clamping rod is provided with a clamping head for clamping the cable tie;

[0010] The driving mechanism includes a driving rod, a first hinge shaft is arranged at the top end of the driving rod, a first connecting rod for mutual hinge connection is arranged between the first hinge shaft and the knife body, a second hinge shaft is also arranged on the driving rod, a second connecting rod for mutual hinge connection is arranged between the second hinge shaft and the clamping rod, a linkage component is arranged between the clamping rod and the first hinge shaft, and a driving component for driving the driving rod to move is arranged on the shell.

[0011] To implement the above technical solution, the driving assembly drives the driving rod to move, and the driving rod is restricted by the linkage assembly and will first drive the clamping rod to move, thereby clamping the tail of the cable tie through the clamping head at the end of the clamping rod, thereby achieving the effect of tightening the cable tie. When the cable tie is tightened and the clamping rod cannot move backward, the linkage assembly drives the knife body to rotate, so that the cutter at the end of the knife body cuts off the excess cable tie, thereby achieving the effect of automatically tightening and cutting the cable tie.

[0012] As a preferred solution of the present application, the driving assembly includes a driving motor arranged on a shell, a crankshaft rocker is arranged on the output shaft of the driving motor, a driving slide rail is arranged on the shell, a T-shaped sliding block is arranged in the driving slide rail, a vertical sliding groove is arranged on the T-shaped sliding block, the crankshaft rocker is inserted in the vertical sliding groove, and the T-shaped sliding block is hinged to the driving rod.

[0013] To implement the above technical solution, the crankshaft rocker is inserted in the vertical slide groove, so that when the drive motor rotates, it can drive the T-shaped sliding block to move back and forth along the driving slide rail through the driving rocker. The T-shaped sliding block is hinged to the driving rod, so that the T-shaped slide rail can drive the driving rod to move.

[0014] As a preferred solution of the present application, a tension spring is provided between the knife body and the cross slide.

[0015] The above technical solution is implemented so that the tension spring can bring the knife body and the cross slide rail closer to each other and return to their original positions.

[0016] As a preferred solution of the present application, the linkage assembly includes a positioning block rotatably arranged on the shell, the positioning block is provided with a positioning groove for clamping the first hinge shaft, and the shell is provided with an elastic member for tightening the positioning block to prevent the positioning block from rotating; a linkage member is provided between the positioning block and the clamping rod for overcoming the elastic force of the elastic member to push the positioning block to rotate and release the first hinge shaft.

[0017] To implement the above technical solution, that is, in a normal state, the first hinge shaft is clamped in the clamping groove under the action of the elastic member and will not move. When the driving assembly drives the driving rod to move, the driving rod will rotate around the clamping groove, thereby driving the clamping rod to move, thereby tightening the cable tie. After tightening, when the driving assembly drives the driving rod, the clamping rod will overcome the elastic member through the linkage member to drive the positioning block to rotate, thereby releasing the first hinge shaft from the positioning groove and moving, thereby driving the knife body to move, and then driving the knife head to cut off the cable tie.

[0018] As a preferred solution of the present application, the elastic member includes a pull rod hinged on the positioning block, an abutment ring is provided at one end of the pull rod away from the positioning block, an abutment platform is provided between the abutment ring and the positioning block, the abutment platform is provided on the shell, and a spring is provided between the abutment platform and the abutment ring.

[0019] By implementing the above technical solution, the abutting ring platform is moved away from the positioning block under the action of the spring, so that the pull rod has the effect of tightening the positioning block.

[0020] As a preferred solution of the present application, the elastic member can be configured as a tension spring type elastic element.

[0021] As a preferred solution of the present application, the linkage member includes a driving block rotatably arranged on the shell, the driving block is provided with a push rod abutting the rotating block, the bottom of the driving block is provided with driving teeth, and the clamping rod is provided with a driving rack for cooperating with the driving teeth.

[0022] To implement the above technical solution, when the driving rod rotates around the first hinge axis, it will pull the clamping rod to move backward, so that the clamping head at the end of the clamping rod clamps the tail of the cable tie and moves, thereby tightening the cable tie. When the cable tie is tightened, the clamping rod is subjected to a certain resistance, which will cause the driving rod to continue to pull the clamping rod, and the clamping rod will rotate around the limit column, and the driving rack at the tail of the clamping rod will move upward and engage with the driving teeth. At this time, the driving rack continues to be driven backward by the driving rod, thereby driving the driving block to rotate, and the push rod on the driving block will push the positioning block to make the positioning block overcome the elastic force of the elastic member and rotate, thereby releasing the first hinge axis from the positioning groove of the positioning block, thereby causing the first hinge axis part of the driving rod to move, thereby pushing the knife body to rotate through the first connecting rod, thereby driving the knife head to move up and automatically cut off the cable tie, that is, achieving the effect of automatically tightening and cutting the cable tie.

[0023] As a preferred solution of the present application, the chuck includes a pressing plate fixed on the clamping rod, a clamping plate is arranged below the pressing plate, and the clamping plate is rotatably arranged on the clamping rod.

[0024] The above technical solution is realized by clamping the cable tie by rotating the clamping plate.

[0025] As a preferred solution of the present application, a clamping tooth for clamping with a cable tie is arranged on the top of the clamping plate, and the clamping tooth is arranged obliquely in a direction away from the cutter head.

[0026] By implementing the above technical solution, when the clamping rod moves backward (away from the direction of the cutting head), the cable tie will be clamped on the clamping teeth, which will pull the cable tie backward. When the end of the cable tie is blocked, the clamping plate will be pulled to rotate, so that the clamping plate and the pressure plate clamp the cable tie, thereby leading to the gradual tightening of the cable tie. If the clamping rod retracts, the cable tie will not be clamped by the clamping teeth because the clamping teeth are set in an inclined direction. The clamping rod drives the clamp head forward and back to the initial position, waiting for the clamping rod to be pulled back to continue tightening the cable tie.

[0027] As a preferred solution of the present application, a battery pack for supplying power to the drive motor can be detachably provided on the shell.

[0028] The above technical solution is implemented to make the cable tie machine as a whole portable and easy to use.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The driving rod is driven to move by the driving assembly. After being restricted by the linkage assembly, the driving rod first drives the clamping rod to move, thereby clamping the tail of the cable tie through the clamp at the end of the clamping rod, thereby achieving the effect of tightening the cable tie. When the cable tie is tightened and the clamping rod cannot move backward, the linkage assembly drives the cutter body to rotate, so that the cutter at the end of the cutter body cuts off the excess cable tie, thereby achieving the effect of automatically tightening and cutting the cable tie;

[0031] 2. The crankshaft rocker is inserted in the vertical slide groove, so that when the driving motor rotates, it can drive the T-shaped sliding block to move back and forth along the driving slide rail through the driving rocker.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] The present application embodiment discloses an electric cable tie machine.

[0042] The tightening mechanism 2 includes a clamping rod 21 slidably arranged on the shell 1, a transverse sliding groove 22 is arranged on the shell 1, and a limiting column 23 inserted in the transverse sliding groove 22 is arranged on the clamping rod 21, so that the clamping rod 21 can move back and forth along the transverse sliding groove 22 and can rotate around the limiting column 23.

The caliper is inclined in the direction away from the cutting head 32, so that when the clamping rod 21 moves backward (away from the cutting head 32), the cable tie will be clamped on the clamping tooth 26, which will pull the cable tie to move backward. When the end of the cable tie is blocked, the clamping plate 25 will be pulled to rotate, so that the clamping plate 25 and the pressure plate 24 clamp the cable tie, thereby leading to the effect of gradually tightening the cable tie. If the clamp rod 21 retreats, the cable tie will not be caught by the latch teeth 26 because the latch teeth 26 are tilted, and the clamp rod 21 drives the clamp head to move forward and retreat to the initial position, waiting for the clamp rod 21 to be pulled back to continue tightening the cable tie.

[0043] The driving mechanism 4 includes a driving rod 41, a first hinge shaft 42 is provided at the top of the driving rod 41, a first connecting rod 43 for mutual hinge connection is provided between the first hinge shaft 42 and the blade body 31, a second hinge shaft 44 is also provided on the driving rod 41, a second connecting rod 45 for mutual hinge connection is provided between the second hinge shaft 44 and the clamping rod 21, and a linkage assembly 46 is provided between the clamping rod 21 and the first hinge shaft 42.

A linkage member 464 is arranged between the positioning block 461 and the clamping rod 21 for overcoming the elastic force of the elastic member 463 to push the positioning block 461 to rotate, thereby releasing the first hinge shaft 42. The elastic member 463 can be set as an elastic element such as a tension spring 474 and a leaf spring. The elastic member 463 in this embodiment includes a pull rod 4631 hinged on the positioning block 461, and an abutment ring 4632 is provided at one end of the pull rod 4631 away from the positioning block 461, an abutment platform 4633 is provided between the abutment ring 4632 and the positioning block 461, and the abutment platform 4633 is provided on the shell 1, and a spring 4634 is provided between the abutment platform 4633 and the abutment ring 4632, so that the abutment ring 4632 is away from the positioning block 461 under the action of the spring 4634, thereby achieving the effect of the pull rod 4631 tightening the positioning block 461.

[0045] The linkage member 464 includes a driving block 4641 rotatably arranged on the housing 1, a push rod 4642 abutting against the rotating block is arranged on the driving block 4641, a driving tooth 4643 is arranged at the bottom of the driving block 4641, and a driving rack 4644 for cooperating with the driving tooth 4643 is arranged on the clamping rod 21, that is, when the driving rod 41 rotates around the first hinge shaft 42, the clamping rod 21 will be pulled to move backward, so that the clamping head at the end of the clamping rod 21 clamps the tail of the cable tie and moves, thereby tightening the cable tie. When the cable tie is tightened, the clamping rod 21 is subjected to a certain resistance, which will cause the driving rod 41 to continue to pull the clamping rod 21, and the clamping rod 21 will rotate around the limit column 23, and the tail of the clamping rod 21 The driving rack 4644 moves upward and engages with the driving tooth 4643. At this time, the driving rack 4644 continues to be driven backward by the driving rod 41, thereby driving the driving block 4641 to rotate. The push rod 4642 on the driving block 4641 will push the positioning block 461, so that the positioning block 461 overcomes the elastic force of the elastic member 463 and rotates, thereby releasing the first hinge shaft 42 from the positioning groove 462 of the positioning block 461, thereby causing the first hinge shaft 42 part of the driving rod 41 to move, thereby pushing the knife body 31 to rotate through the first connecting rod 43, thereby driving the knife head 32 to move upward to automatically cut off the cable tie, that is, achieving the effect of automatically tightening and cutting the cable tie.

In order to ensure the reset effect, a tension spring 474 is arranged between the knife bar and the cross slide block, so that the tension spring 474 can make the knife bar and the cross slide rail close to each other and return to their original positions. The housing 1 may also be detachably provided with a battery pack 475 for supplying power to the driving motor 471, so that the cable tie machine as a whole is portable and easy to use.
