Description

Technical Field

[0001] The utility model relates to the technical field of cable tie machines, in particular to a cable tie machine gun head with a buffer component. Background Art

[0002] For the automatic bundling of ordinary nylon cable ties, there is a desktop cable tie machine design in China. This machine has the following disadvantages: the machine is fixed and can only move the workpiece, which is inflexible to use; due to space limitations, it cannot be used for on-site or internal construction of aircraft, ships, trains, cars, gas stations, pipelines of communication equipment, tunnels or aerial cables, etc.; the desktop cable tie machine also has some design defects, making it inconvenient and unreliable to use; moreover, the desktop automatic cable tie machines on the market generally use five motors to drive, which wastes parts and is bulky.

[0003] In view of this, some handheld cable tie machines have appeared on the market, which are convenient to use. For example, the cable tie machine with a waste collection box disclosed in authorization CN220536024U specifically discloses a shell, a frame arranged on the shell, and guide claws, a push rod and a tensioning mechanism respectively arranged on the frame. The guide claws include a first guide claw and a second guide claw respectively hinged on the frame and cooperating with each other, and the first guide claw and the second guide claw are both provided with guide grooves that cooperate with each other, the two ends of the push rod are respectively connected to the first guide claw and a cylinder, and a through hole with a side wall as a cutter is provided on the push rod, the tensioning mechanism is located above the through hole and the tensioning mechanism includes a pull belt driving wheel, a pull belt passive wheel and a motor used as a power source, and also includes a waste collection box installed on the frame; the waste collection box corresponds to the tensioning mechanism so that the pull belt driving wheel and the pull belt passive wheel can be used to send waste into the waste collection box through the entrance of the waste collection box. A locking position for locking the head of the cable tie is also provided on the frame.

[0004] However, in the aforementioned cable tie machine with a waste collection box, since the cable tie is fed into the cable tie guide rail via a feeding mechanism and then transported to the first guide claw and the second guide claw via the cable tie guide rail, the locking position is used to position the head of the cable tie to prevent its position from being inaccurate and affecting the bundling effect. However, since the cable tie moves at a very high speed during transportation, and since the locking position needs to position the high-speed moving cable tie head, the cable tie head often hits the front side wall of the locking position when it moves to the locking position, forcing the cable tie head to stop from its high speed. In this case, the cable tie head will generate a high impact force on the front side wall of the locking position, which can easily cause the cable tie head to break, thereby affecting the bundling effect.

DETAILED DESCRIPTION

[0027] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0028] like Figures 1-6 As shown, a cable tie machine gun head with a buffer assembly includes a shell 1, a frame 2 arranged on the shell 1, and a guide claw 3 and a buffer assembly 4 respectively arranged on the frame 2.

[0029] like Figures 2-4 As shown, the guide claw 3 includes a first guide claw 31 and a second guide claw 32 which are respectively hinged on the frame 2 and cooperate with each other. The first guide claw 31 and the second guide claw 32 are both provided with a guide groove 33 that cooperates with each other for guiding the operation of the cable tie.

[0030] like Figures 2-4 As shown, the frame 2 is provided with a first tie channel 21, a locking position 22, and a second tie channel 26 which are connected in sequence from front to back and respectively cooperate with the guide groove 33; the locking position 22 can be used to lock the head of the tie; in addition, the width of the locking position 22 and the width of the second tie channel 26 are respectively greater than the width of the first tie channel 21.

[0031] like Figures 2-5 As shown, the buffer assembly 4 includes a buffer block 41 and an elastic member 42; a limiting hole 24 opening toward the rear is provided on one side wall of the rear port of the first cable tie channel 21; the buffer block 41 can be installed in the limiting hole 24 so as to be movable forward and backward and the rear end of the buffer block 41 is connected to the locking position 22, that is, the rear end face of the buffer block 41 is equivalent to a part of the front side face of the locking position 22, so as to facilitate the subsequent abutment between the cable tie head and the rear end of the buffer block 41; the elastic member 42 is installed in the limiting hole 24 and its front and rear ends are respectively connected to the frame 2 and the buffer block 41; the buffer assembly 4 can be used to buffer the cable tie head to prevent the cable tie head from breaking when it runs to the locking position 22.

[0032] like Figures 2-6 As shown, the first guide claw 31 can be hooked inward by a push rod 5 and a drive device, which is used to drive the push rod 5. The push rod 5 is mounted on the frame 2 and has a through hole 51 extending through its upper and lower end surfaces, through which the tail of the cable tie can pass. The through hole 51 corresponds to a through hole 23 in the locking position 22 and is located above the locking position 22. A cutter 7 is provided on the front side wall of the through hole 51. Therefore, through this arrangement, the drive device can be used to drive the first guide claw 31 to perform the corresponding movement, and the cutter 7 can be used to cut the cable tie.

[0033] In this embodiment, if Figure 6As shown, a slope extending backward is provided on the front side wall of the through hole 51 to form the cutter 7. Since the cutter 7 is a prior art, it will not be described in detail here.

[0034] like Figure 5 As shown, a mounting hole 43 is provided at the front end of the buffer block 41, and the rear end of the elastic member 42 is matched and mounted in the mounting hole 43. The above arrangement facilitates positioning of the buffer block 41 and the elastic member 42.

[0035] like Figures 2-3 As shown, an arcuate surface 27 is provided on the other side wall of the rear end of the first cable tie channel 21, so that the tail of the cable tie can pass through the first cable tie channel 21 more smoothly and is less likely to get stuck.

[0036] like Figure 1 As shown, one side of the limiting hole 24 extends to a side surface of the frame 2, so that the buffer assembly 4 can be installed from the side of the frame 2. Of course, other baffles (not shown) can be installed on the side of the frame 2 to cover the buffer assembly 4, or a positioning rod (not shown) fixed to the frame 2 can be installed through the middle of the elastic member 42 to prevent the buffer assembly 4 from loosening.

[0037] In this embodiment, the elastic member 42 is a spring. However, those skilled in the art will appreciate that the elastic member 42 can be made of other materials as long as they can provide sufficient elastic force for the buffer block 41 .

[0038] like Figure 4 As shown, a sliding groove 25 for the push rod 5 to slide is provided in the frame 2, thereby ensuring the movement stability of the push rod 5.

[0039] In this embodiment, the driving device is a cylinder 6 .

[0040] The present invention also includes a tensioning mechanism (not shown) mounted on the frame 2 and used to pull the cable tie. Since the tensioning mechanism is prior art, no further description will be given here.

[0041] Of course, the present invention is also provided with a trigger (not shown in the figure) for controlling the second guide claw 32 to flip up and down. Since this structure is a prior art, it will not be described in detail here.

[0042] The specific operating principle of the utility model is introduced below to facilitate understanding of the utility model:

[0043] First, press the trigger to close the first guide claw 31 and the second guide claw 32; next, the feeding mechanism (not shown) starts feeding and feeds the cable tie forward along the second cable tie channel 26. In the process of feeding the cable tie forward, its tail portion passes through the locking position 22 and the first cable tie channel 21 and then enters the guide groove 33 of the first guide claw 31 and the guide groove 33 of the second guide claw 32 in sequence, until the head of the cable tie moves to the locking position 22, where it hits the buffer block 41 and pushes the elastic member 42 to compress a certain distance, so that the buffer block 41 can play a buffering role for the head of the cable tie; next, after the impact force of the cable tie head is weakened, the elastic member 42 is compressed. During the restoration process, the elastic member 42 utilizes the buffer block 41 to push the head of the cable tie to a preset position. At this point, a portion of the tail of the cable tie just fits into the hole in the head of the cable tie. Next, the cylinder 6 is activated, pushing the push rod 5 forward and simultaneously driving the first guide claw 31 inward, so that the tail of the cable tie passes through the through-hole 51 of the push rod 5 and is tightened by the tensioning mechanism. Next, after the cable tie is tightened, the cylinder 6 resets, causing the push rod 5 to move backward synchronously. As the push rod 5 moves, the cutter 7 cuts the tail of the cable tie in the through-hole 51. After the tail of the cable tie is cut, the tensioning mechanism continues to pull the cut waste material outward to the next step. Therefore, after the above steps, the process of bundling items with a cable tie is completed.

[0044] In summary, the present invention sets the buffer assembly 4 in front of the locking position 22, so that the cooperation of the buffer block 41 and the elastic member 42 can be used to buffer the head of the cable tie, reduce the impact force, and effectively prevent the head of the cable tie from breaking during the transportation of the cable tie, thereby improving the stability of the tool during operation and having strong practicality.

[0045] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
