[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] It should be noted that in this invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element of this invention must have a specific orientation, and therefore should not be construed as a limitation of this invention. Example 1

[0034] Cooperate Figs. 1 to 3 As shown, the present invention discloses an electric belt tightening machine, including a housing 1, a cutting mechanism 2, a tightening mechanism 3 and a speed control switch 4 mounted on the housing 1.

[0035] The outer casing 1 contains a controller 11, which can also be a control motherboard.

[0036] The cutting mechanism 2 includes a cutting blade holder 21, a cutting blade 22, and a cutting blade rod 23. The cutting blade holder 21 is installed on one side of the housing 1 and has a communicating cutting port 211 and a cable tie channel 212. The cutting port 211 is a circular structure, and the cable tie channel 212 is a horizontal channel. The cutting blade 22 is rotatably installed in the cutting port 211, with one end extending outside the cutting blade holder 21. One end of the cutting blade rod 23 is installed with the cutting blade holder 21.

[0037] The tightening mechanism 3 includes a tightening motor 31 and a rotating shaft 32. The tightening motor 31 is built into the housing 1, and the rotating shaft 32 is mounted on the housing 1 and located at the rear end of the cutting blade holder 21. The tightening motor 31 drives the rotating shaft 32 to rotate.

[0038] Speed ​​control switch 4 is installed on housing 1 and connected to controller 11. Speed ​​control switch 4 controls the speed of tightening motor 31. After the cable tie is tied, its tail first enters the cable tie channel 212 at the front of the cutting knife holder 21, passes through the cutting opening 211, and then exits the cable tie channel 212 at the rear and enters the rotating shaft 32. The tightening motor 31 controls the rotating shaft 32 to rotate and pull the cable tie through the cutting knife holder 21. After tightening the cable tie, the cutting knife 22 is driven to rotate by rotating the cutting knife bar 23. The cutting knife 22 cuts the tail of the cable tie in the cutting opening 211.

[0039] The outer casing 1 includes a main body 12, a base plate 13, and a grip 14. The main body 12 and the grip 14 are arranged vertically. The grip 14 is provided with a switch port. The speed control switch 4 is movably mounted on the switch port through an elastic reset member. The base plate 13 is provided on the side wall of the main body 12 and has an extension 131 placed at the front end of the main body 12. The main body 12 and the base plate 13 are provided with a corresponding shaft hole. The rotating shaft 32 passes through the shaft hole and is connected to the tightening motor 31 inside the main body 12.

[0040] In this embodiment, the elastic reset element is preferably a spring or a reset clamp, which is set inside the grip 14 and its end is installed with the adjustment switch. When the adjustment switch is pressed down, it squeezes the reset elastic element. When it is released, the speed control switch 4 is pushed out of the switch port. In this embodiment, the speed control switch 4 is a limit switch. The change in its travel is fed back to the controller 11, thereby controlling the speed change of the tightening motor 31. The more it is pressed down, the faster the speed, and vice versa.

[0041] The outer shell 1 is composed of a left shell and a right shell joined together, and the preferred method of joining and fixing is screw installation.

[0042] This embodiment also includes a battery holder 5. The bottom of the grip 14 is provided with a battery mounting port. The battery holder 5 is detachably installed in the battery mounting port. A limiting block is provided in the battery mounting port. The battery holder 5 is provided with elastic plates and blocks on both sides. The elastic blocks are arranged on the left and right and inserted into the battery mounting port. The elastic plates engage with the internal limiting blocks through the blocks. To remove it, simply press the two elastic plates inward at the same time, and the blocks will disengage from the limiting blocks. The battery holder 5 has a built-in battery and is connected to the controller 11 to supply power to it and the tightening motor 31.

[0043] The substrate 13 has a blade hole in the extension 131 that is opposite to the cutting opening 211. The cutting blade 22 is rotatably mounted in the blade hole through a limiting washer. Its cutting head is located in the cutting opening 211 of the cutting blade holder 21, and its cutting body is located outside the cutting blade holder 21. The cutting blade body has an insertion opening, and the cutting blade rod 23 is inserted into the insertion opening. By rotating the cutting blade rod 23, the cutting blade 22 is driven to rotate, and the cutting blade 22 rotates to cut the cable tie at the cutting opening 211.

[0044] The cutting blade 23 is inserted into the insertion port from top to bottom or from bottom to top. When the cutting blade 23 is inserted into the insertion port from top to bottom, rotating the cutting blade 23 will cause it to move clockwise toward the outer casing 1. When the cutting blade 23 is inserted into the insertion port from bottom to top, rotating the cutting blade 23 will cause it to move counterclockwise toward the outer casing 1.

[0045] The substrate 13, the main body 12, and the cutting blade holder 21 are each provided with multiple aligning screw holes. The substrate 13 is mounted to the main body 12 with screws, and the cutting blade holder 21 is detachably mounted to the extension 131 of the substrate 13 with screws. Different specifications of the cutting blade holder 21 can be replaced by disassembling the substrate 13. By detachably mounting the cutting blade holder 21 on the substrate 13 and switching between different specifications of the cutting blade holder 21, the requirements for different lengths of tape tail after cutting can be met, flexibly satisfying the usage needs in different scenarios. Among them, the cutting blade holder 21 with different specifications corresponds to different structures, which can be triangular, square, or circular. By replacing the front cable tie channel 212 of different lengths, the usage requirements for different length tails can be met.

[0046] An elastic band is fitted over the cutting blade body of the cutting blade 22. The elastic band is installed with the cutting blade rod 23. The elastic band pushes the cutting blade rod 23 back to its original position and away from the outer casing 1. In this embodiment, the main body 12 has a limiting protrusion at the front end. One end of the elastic band cooperates with the limiting protrusion to fix the elastic band. It can be fixed by adhesive, insertion, or screw installation. The other end cooperates with the cutting blade rod 23. Rotating the cutting blade rod 23 compresses the elastic band. When released, the elastic band pushes it back to its original position.

[0047] The controller 11 is equipped with an overcurrent protection module, which monitors the current of the tightening motor 31 and feeds it back to the controller 11 to control the switching of the tightening motor 31. By monitoring the tightening current, the power can be automatically cut off after tightening. This eliminates the need for manual observation of whether tightening has occurred and protects the tightening motor 31 from overcurrent damage, thus extending its service life.

[0048] In this embodiment, the tightening motor 31 can be a right-angle motor that directly drives the rotating shaft 32 to rotate, or it can be a structure where the motor works in conjunction with a reducer, with the motor driving the reducer and the reducer driving the rotating shaft 32 to rotate. The motor can be a brushless motor.

[0049] In this embodiment, the overcurrent protection module is an external overcurrent protector or an overcurrent protection circuit is provided on the panel of the controller 11. By adjusting the size of the maximum overcurrent protection, different maximum tightening force requirements can be adjusted. At the same time, when the tightening force reaches the maximum value of the current setting, the motor stops rotating to avoid burning out the tightening motor 31. It can also avoid strong impact on the gears and screws of the reducer and extend their service life.

[0050] Compared to mechanical methods, such as adjusting the tension force with springs and adjusting the distance of the reducer gears to avoid greater gear impact, this embodiment uses current adjustment to simplify the tool structure, making the tool smaller, lighter, and with a longer service life.

[0051] The rotating shaft 32 is provided with a cross-shaped opening or a star-shaped opening.

[0052] In this embodiment, after the cable tie is bundled, its tail first passes through the cable tie channel 212 at the front of the cutting knife holder 21, through the cutting opening 211, and then out through the cable tie channel 212 at the rear to enter the rotating shaft 32. The user presses the speed control switch 4 to control the speed of the tightening motor 31. The rotating shaft 32 rotates and pulls the cable tie through the cutting knife holder 21, replacing manual operation to tighten the cable tie. Then, by rotating the cutting knife bar 23, the cutting knife 22 is driven to rotate. The cutting knife 22 cuts the tail of the cable tie in the cutting opening 211, realizing the automatic tightening and rapid cutting of the cable tie, reducing manual operation time and improving work efficiency. Example 2

[0053] This embodiment describes a method for using an electric belt tensioning machine, as described above, including the following specific steps:

[0054] S1. First, tie the cable ties, leaving them in a loose state.

[0055] S2. Replace the cable tie cutter holder with the corresponding specification in S1, and reset the cutter.

[0056] S3. Grab the end of the cable tie, insert the end of the cable tie into the front cable tie channel of the cutter holder, and then pass it through the cut and the rear cable tie channel in sequence.

[0057] S4. Insert the cable tie tail into the rotating shaft, then press the speed control switch. The speed control switch connects to the controller, which controls the tightening motor to work. The tightening motor drives the rotating shaft to rotate and tighten the cable tie. The cable tie tail in the loose state passes through the cutting knife seat and the rotating shaft in sequence and then turns into the tightened state. When the tightening motor encounters resistance, the current changes. When the current reaches the set value, the built-in overcurrent protection board will cut off the power and stop the machine.

[0058] S5. By rotating the cutting blade bar, the cutting blade is driven to rotate. The cutting blade rotates at the cutting point to cut the cable tie and remove the tail material from the rotating shaft to complete the tightening operation.

[0059] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
