Description

Technical Field

[0001] This utility model relates to the field of cable cutting equipment technology, and in particular to a cutting device for processing rubber cables. Background Technology

[0002] Rubber cables are cables with rubber as insulation and sheath. They are characterized by flexibility, wear resistance, and water resistance, making them suitable for mobile applications or harsh outdoor environments. Rubber cables are generally packaged in a winding manner. When the winding roller reaches the target thickness, the cable needs to be cut before installing the next empty winding roller. The cut cable end is then connected to this empty winding roller for further packaging. However, existing rubber cable cutting devices generally have non-movable cutters. This leads to common operational difficulties or the risk of accidental injury from the cutter when connecting the cable end to the empty winding roller.

[0003] For example, a cable cutting device is disclosed in Chinese utility model patent with announcement number CN210586887U. Although the cylinder of this solution can drive the arc blade to move down quickly to cut the cable through the slide rod, it has the advantages of being suitable for cutting cables of different diameters, having a wide range of applications, and good cutting stability. However, the cut rubber cable ends will be scattered on one side of the arc blade. When connecting the rubber cable ends to a new take-up roller for packaging and bundling, a manual arm needs to be inserted near the arc blade and then pass under the arc blade to connect to the empty take-up roller. This not only makes the take-up and packaging difficult, but also easily causes the worker's arm to be cut due to accidental contact with the blade.

[0004] In view of this, a cutting device for processing rubber cables is proposed that can solve the above problems. Utility Model Content

[0005] To address the technical problem of convenient use of rubber cable cutting devices, this utility model provides a cutting device for rubber cable processing.

[0006] This utility model is achieved using the following technical solution: a cutting device for processing rubber cables, comprising a base, a limiting cylinder installed on one side of the base, a spiral groove and a straight groove respectively opened on the limiting cylinder, the lower end of the spiral groove communicating with the upper end of the straight groove, a knife bar slidably connected to the inner side of the spiral groove, a knife holder fixedly connected to the end of the knife bar away from the limiting cylinder, a pressure knife installed on the lower side of the knife holder, a pressure knife retraction mechanism provided on the limiting cylinder for transferring the pressure knife from one side to the other side, and a cutting and winding mechanism provided on the side of the base away from the limiting cylinder.

[0007] As a further improvement to the above solution, the pressing and releasing mechanism includes multiple sliding rods fixedly connected between the upper and lower sides inside the limiting cylinder. The multiple sliding rods are arranged in a circumferential array, and a piston is slidably connected to the multiple sliding rods. The outer side of the piston is slidably connected to the inner side of the limiting cylinder. A piston pushing mechanism is provided on the upper side of the limiting cylinder to make the piston move up and down along the sliding rods. A tool rod driving mechanism is provided on the lower side of the piston to push the tool rod to slide along the inner side of the spiral groove.

[0008] As a further improvement to the above solution, the piston pushing mechanism includes a servo motor mounted on the upper side of the limiting cylinder. The output end of the servo motor extends into the interior of the limiting cylinder and is fixedly connected to a threaded rod. The threaded rod is threadedly sleeved with the piston, and the lower end of the threaded rod is rotatably connected to the bottom side of the limiting cylinder.

[0009] As a further improvement to the above solution, the tool holder drive mechanism includes a turntable rotatably connected to the lower side of the piston, and the outer side of the turntable is fixedly connected to one end of the tool holder.

[0010] As a further improvement to the above solution, the cutting and winding mechanism includes a cutting table fixedly connected to the upper side of the base, an LED industrial control panel is installed on the upper side of the cutting table, a cutting groove is opened on the cutting table, the cutting groove is configured to cooperate with the pressure knife, and a winding mechanism is provided on one side of the cutting table.

[0011] As a further improvement to the above solution, the winding mechanism includes a plurality of winding rollers rotatably connected to one side of the cutting table, and the plurality of winding rollers are distributed in a linear array.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a servo motor to drive the threaded rod to rotate. Under the action of the sliding rod limit, the piston moves up and down. The movement of the piston indirectly drives the turntable to move up and down. At the same time, the cutter bar on the turntable shifts with the spiral groove, so that when the cable needs to be cut, the pressure knife rotates to one side and presses down to cut. After the cutting is completed, it returns to its original position for storage, freeing up the space above the cutting table so as not to affect the staff to take the rubber cable cutter head. It has the advantage of being easy to use.

[0014] 2. This utility model allows the cutting bar to slide upwards inside the straight groove and the spiral groove, transferring the pressure knife away from the cutting table after the cable is cut. This avoids the possibility of workers' arms being cut by the pressure knife due to mistakes, and has the advantage of making the operation and processing safer and more reliable.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please combine Figures 1-3 The cutting device for processing rubber cables according to this embodiment includes a base 1, and a limiting cylinder 3 is installed on one side of the base 1. In this embodiment, the limiting cylinder 3 has a hollow structure.

[0023] Please combine Figure 2 As shown, the limiting cylinder 3 is provided with a spiral groove 5 and a straight groove 8 respectively. The lower end of the spiral groove 5 is connected to the upper end of the straight groove 8. It should be noted that in this embodiment, the spiral groove 5 is twisted by 90 degrees, that is, a quarter turn. In other embodiments, the degree of twist can be set according to the relative deflection position of the limiting cylinder 3 and the cutting table 2, or the angle relationship after the cable is straightened.

[0024] By sliding the tool holder 6 within the spiral groove 5, the pressing tool 10 can be shifted from one side or stored on the other side.

[0025] By sliding the cutter bar 6 within the linear slot 8, the pressure cutter 10 achieves the function of cutting the cable from top to bottom;

[0026] Referring to Figure 3, a blade 6 is slidably connected to the inner side of the spiral groove 5. A blade holder 7 is fixedly connected to the end of the blade 6 away from the limiting cylinder 3. The blade holder 7 is fixed by bolts. A pressure knife 10 is installed on the lower side of the blade holder 7. The blade holder 7 and the pressure knife 10 are detachably installed. A pressure knife retraction mechanism is provided on the limiting cylinder 3 to transfer the pressure knife 10 from one side to the other side. A cutting and winding mechanism is provided on the side of the base 1 away from the limiting cylinder 3.

[0027] Please combine Figure 3 As shown, the pressing and releasing mechanism includes three sliding rods 13 fixedly connected between the upper and lower sides inside the limiting cylinder 3. The three sliding rods 13 are arranged in a circular array. A piston 14 is slidably connected to the three sliding rods 13. In this embodiment, the piston 14 is made of metal and mainly provides support for the rotation of the turntable 15.

[0028] Please combine Figure 2 As shown, the outer side of piston 14 is slidably connected to the inner side of limiting cylinder 3. The upper side of limiting cylinder 3 is provided with a piston pushing mechanism that causes piston 14 to move up and down along slide rod 13. The lower side of piston 14 is provided with a tool rod driving mechanism that pushes tool rod 6 to slide along the inner side of spiral groove 5.

[0029] Please combine Figure 1 The piston pushing mechanism includes a servo motor 4 mounted on the upper side of the limiting cylinder 3. The output end of the servo motor 4 extends into the limiting cylinder 3 and is fixedly connected to a threaded rod 12. The threaded rod 12 is threadedly connected to the piston 14, and the lower end of the threaded rod 12 is rotatably connected to the bottom side of the limiting cylinder 3.

[0030] Please combine Figure 2 As shown, the tool holder drive mechanism includes a turntable 15 rotatably connected to the lower side of the piston 14, and the outer side of the turntable 15 is fixedly connected to one end of the tool holder 6.

[0031] In this embodiment, when the tool holder 6 slides downward inside the spiral groove 5, it drives the turntable 15 to rotate clockwise.

[0032] When the tool holder 6 slides upward inside the spiral groove 5, it drives the turntable 15 to rotate clockwise and counterclockwise.

[0033] Please combine Figure 1 As shown, the cutting and winding mechanism includes a cutting table 2 fixedly connected to the upper side of the base 1. An LED industrial control panel is installed on the upper side of the cutting table 2. The LED industrial control panel is equipped with control switch buttons, which can control the start and stop of the servo motor 4.

[0034] Please combine Figure 1 As shown, a cutting groove 11 is provided on the cutting table 2. The cutting groove 11 is used to protect the pressure knife 10 from blunt damage.

[0035] Please combine Figure 1As shown, the cutting groove 11 is configured to cooperate with the pressure knife 10. A winding mechanism is provided on one side of the cutting table 2. The winding mechanism includes multiple winding rollers 9 that are rotatably connected to one side of the cutting table 2. The multiple winding rollers 9 are arranged in a linear array. The multiple winding rollers 9 can be disassembled and installed through a clamping mechanism on one side.

[0036] The implementation principle of the cutting device for rubber cable processing in this embodiment is as follows: When multiple winding rollers 9 have finished winding the rubber cable, and multiple cables need to be cut, the servo motor 4 is started by the LED industrial control panel button, which drives the threaded rod 12 to rotate. Under the action of the slide rod 13 on the piston 14, the threaded rod 12 pushes the piston 14 to move downward along the slide rod 13, and at the same time pushes the turntable 15 to slide downward. Since the cutter bar 6 installed on the turntable 15 is restricted by the spiral groove 5 and the straight groove 8, when the turntable 15 moves downward, the turntable 15 rotates relative to the piston 14 along the spiral groove 5. Then the cutter bar 6 moves from the spiral groove 5 to slide into the inner side of the straight groove 8, thereby driving the cutter holder 7 to press down through the cutter bar 6, realizing the engagement of the pressure cutter 10 and the cutting groove 11, and achieving the function of cable cutting.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
