Description
Technical Field
[0001] This utility model relates to the field of cable technology, and in particular to a rapid cutting device for medium-wave high-frequency coaxial cables. Background Technology
[0002] Medium-wave and high-frequency coaxial cables are used to transmit medium-wave and high-frequency signals and are widely used in broadcasting, communications, and television. Medium-wave typically refers to radio waves with frequencies between 530kHz and 1700kHz, while high-frequency typically refers to frequencies between 3MHz and 30MHz. The structural features of a coaxial cable consist of an inner conductor, an insulation layer, an outer conductor, and an outer sheath. This structure effectively shields against electromagnetic interference, reduces signal loss, and improves signal transmission quality. With the rapid development of communication technology, the demand for medium-wave and high-frequency signal transmission is increasing. Coaxial cables, due to their excellent transmission characteristics and anti-interference capabilities, are widely used in broadcasting, television, data transmission, and other fields. In actual production and installation, coaxial cables often need to be cut to the appropriate length for specific applications, thus requiring a rapid cutting device for medium-wave and high-frequency coaxial cables.
[0003] In the traditional cutting device, due to the lack of an effective fixing mechanism, the cable is prone to displacement when the cutting force is applied by the blade. This displacement directly leads to inaccurate cutting length, causing dimensional errors and affecting the reliability of subsequent applications. In addition, the traditional cutting device requires fixing the cable first, and then manually releasing the fixing and pulling out the required length after cutting. Since each cutting requires a process of manual fixing, cutting, manual release of fixing and manual fixing again, it takes a long time and reduces work efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid cutting device for medium-wave high-frequency coaxial cables.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rapid cutting device for medium-wave high-frequency coaxial cables includes a base, a bottom plate fixed to one top end of the base, a rectangular block fixed to one side of the top of the bottom plate, and a first trapezoidal block slidably connected to the other top side of the bottom plate. Both the rectangular block and the first trapezoidal block have arc-shaped grooves on their adjacent inner sidewalls. Both the rectangular block and the first trapezoidal block have through slots at their tops, which extend through the bottom of the rectangular block and the first trapezoidal block respectively. A top plate is provided on the top of the bottom plate. A lifting mechanism for raising and lowering the top plate is provided at one top end of the base, and a moving mechanism for moving the first trapezoidal block is provided on one side of the bottom of the top plate. A cutting blade is fixed to the bottom of the top plate, and the cutting blade is adapted to the two through slots. The base has a cable release mechanism at one end and a cable conveying mechanism at the top. It also has a limiting mechanism at the top to restrict cable movement. During use, the device, through the coordination of the conveying mechanism, lifting mechanism, and moving mechanism, achieves automated conveying, fixing, and cutting processes, reducing manual operation steps and significantly shortening the overall cable cutting time, thus improving work efficiency. The rectangular block, first trapezoidal block, arc groove, and through groove effectively fix the cable during cutting, preventing displacement and improving cutting accuracy while reducing dimensional errors.
[0007] Preferably, the cable feeding mechanism includes two first support plates, which are symmetrically fixed to the other end of the top of the base. Each of the two first support plates has a groove on its top. The same first rotating shaft is rotatably connected inside the two grooves. A take-up roller is sleeved on the side wall of the first rotating shaft. The cable is pre-wound onto the side wall of the take-up roller. Then, the two ends of the first rotating shaft are respectively placed inside the two grooves, so that the take-up roller can rotate, which facilitates the cable feeding process.
[0008] Preferably, the conveying mechanism includes two second support plates, which are symmetrically fixed on both sides of the top of the base. Two second rotating shafts are rotatably connected to the inner sidewalls of the two second support plates, and one end of each second rotating shaft passes through the outer sidewall of one of the second support plates. Conveying rollers are sleeved on the sidewalls of the two second rotating shafts, and an annular limiting groove is provided in the middle of the sidewalls of the two conveying rollers. Gears are sleeved on one end of each of the two second rotating shafts, and the two gears mesh. A motor is fixed to the outer sidewall of the other second support plate, and the output shaft of the motor is fixed to one of the second rotating shafts. The motor drives one of the second rotating shafts to rotate, which in turn drives the other second rotating shaft to rotate, thereby causing the two conveying rollers to rotate in a counter-rotating manner, thus enabling the cable to be conveyed.
[0009] Preferably, the limiting mechanism includes two limiting rods, which are symmetrically fixed to the top of the base near the middle of the two conveying rollers. Through the action of the two limiting rods, the cable between the two limiting rods and the two conveying rollers can be kept in a straight line, avoiding the occurrence of uneven cable cutting surfaces in the future.
[0010] Preferably, the lifting mechanism includes two hydraulic push rods, both of which are symmetrically fixed to the other end of the top of the base, and the output ends of both hydraulic push rods are fixed to the top plate. The moving mechanism includes a second trapezoidal block, which is fixed to one side of the bottom of the top plate and is adapted to the first trapezoidal block. A groove is provided on one side of the top of the base plate, and a slide rod is fixed to the inner side wall of the groove. A slider is sleeved on the side wall of the slide rod and is fixed to the first trapezoidal block. A spring is sleeved on the side wall of the slide rod near the rectangular block, driving the two hydraulic push rods to move the top plate downward, thereby moving the cutting blade and the second trapezoidal block downward simultaneously. During the downward movement of the top plate, the second trapezoidal block will contact the first trapezoidal block in advance. When in contact, it will push the first trapezoidal block closer to the groove. As one end of the rectangular block moves, the spring gradually compresses under the action of the slider. Meanwhile, the movement of the first trapezoidal block, combined with two arc-shaped grooves, restricts and fixes the cable, preventing displacement of the cutting position during cutting and avoiding dimensional errors caused by inaccurate cutting lengths. This improves cutting accuracy. After cutting, two hydraulic push rods are driven to move the top plate upwards. At this point, the second trapezoidal block gradually separates from the first trapezoidal block. Under the reaction force of the compressed spring, the slider moves in the opposite direction, causing the first trapezoidal block to gradually move away from the rectangular block. The cable can then continue to be transported. Once the specified length is reached, cutting can be performed again, eliminating the need for manual fixing, cutting, manual unfixing, and re-fixing, saving considerable time and improving work efficiency.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. During use, this device achieves automated conveying, fixing and cutting processes through the cooperation of the conveying mechanism, lifting mechanism and moving mechanism, reducing manual operation steps and significantly shortening the overall cable cutting time, thereby improving work efficiency.
[0013] 2. By setting up rectangular blocks, first trapezoidal blocks, arc grooves and through grooves, the cable can be effectively fixed during the cutting action to prevent displacement of the position during cutting, thereby improving the cutting accuracy and reducing dimensional errors.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1 - Figure 6A rapid cutting device for medium-wave high-frequency coaxial cables includes a base 1, a base plate 4 fixed to one top end of the base 1, a rectangular block 5 fixed to one side of the top of the base plate 4, and a first trapezoidal block 6 slidably connected to the other top side of the base plate 4. Both the rectangular block 5 and the first trapezoidal block 6 have arc-shaped grooves 18 on their adjacent inner sidewalls. Both the rectangular block 5 and the first trapezoidal block 6 have through grooves 19 on their tops, with the two through grooves 19 penetrating the bottom of the rectangular block 5 and the first trapezoidal block 6 respectively. A top plate 7 is provided on the top of the base plate 4. A lifting mechanism for raising and lowering the top plate 7 is provided at one top end of the base 1. A moving mechanism for moving the first trapezoidal block 6 is provided on one side of the bottom of the top plate 7. A cutting blade 24 is fixed to the bottom of the top plate 7, and the cutting blade 24 and the two through grooves 18 are connected to the bottom of the first trapezoidal block 6 respectively. All slots 19 are compatible. The other end of the top of the base 1 is equipped with a cable release mechanism for releasing the cable. The top of the base 1 is equipped with a cable conveying mechanism for conveying the cable. The top of the base 1 is equipped with a limiting mechanism for limiting the cable. During use, the device achieves automated conveying, fixing and cutting processes through the cooperation of the conveying mechanism, lifting mechanism and moving mechanism, reducing manual operation steps and significantly shortening the overall cable cutting time, thereby improving work efficiency. Through the setting of rectangular block 5, first trapezoidal block 6, arc slot 18 and through slot 19, the cable can be effectively fixed during the cutting action to prevent displacement of the position during cutting, thereby improving the cutting accuracy and reducing dimensional errors.
[0023] Furthermore, the cable feeding mechanism includes two first support plates 2, which are symmetrically fixed to the other end of the top of the base 1. Each of the two first support plates 2 has a groove 11 on its top. The same first rotating shaft 12 is rotatably connected inside the two grooves 11. A take-up roller 13 is sleeved on the side wall of the first rotating shaft 12. The cable is pre-wound onto the side wall of the take-up roller 13. Then, the two ends of the first rotating shaft 12 are respectively mounted inside the two grooves 11, so that the take-up roller 13 can rotate, which facilitates the cable feeding process.
[0024] Furthermore, the conveying mechanism includes two second support plates 3, which are symmetrically fixed on both sides of the top of the base 1. Two second rotating shafts 14 are rotatably connected to the inner sidewalls of the two second support plates 3, and one end of each of the two second rotating shafts 14 passes through the outer sidewall of one of the second support plates 3. Conveying rollers 9 are sleeved on the sidewalls of the two second rotating shafts 14, and annular limiting grooves 15 are opened in the middle of the sidewalls of the two conveying rollers 9. Gears 16 are sleeved on one end of each of the two second rotating shafts 14, and the two gears 16 mesh. A motor 17 is fixed to the outer sidewall of the other second support plate 3, and the output shaft of the motor 17 is fixed to one of the second rotating shafts 14. The motor 17 drives one of the second rotating shafts 14 to rotate, and the two gears 16 drive the other second rotating shaft 14 to rotate, thereby driving the two conveying rollers 9 to rotate in a counter-rotating manner, so as to convey the cable.
[0025] Furthermore, the limiting mechanism includes two limiting rods 10, which are symmetrically fixed to the top of the base 1 near the middle of the two conveying rollers 9. Through the action of the two limiting rods 10, the cable between the two limiting rods 10 and the two conveying rollers 9 can be kept in a straight state, avoiding the occurrence of uneven cable cutting surfaces in the future.
[0026] Furthermore, the lifting mechanism includes two hydraulic push rods 8, both of which are symmetrically fixed to the other end of the top of the base 1, and the output ends of both hydraulic push rods 8 are fixed to the top plate 7. The moving mechanism includes a second trapezoidal block 25, which is fixed to one side of the bottom of the top plate 7 and is adapted to the first trapezoidal block 6. A groove 20 is provided on one side of the top of the base plate 4, and a slide rod 21 is fixed to the inner wall of the groove 20. A slider 22 is sleeved on the side wall of the slide rod 21, and the slider 22 is fixed to the first trapezoidal block 6. A spring 23 is sleeved on the side wall of the slide rod 21 near the rectangular block 5, which drives the two hydraulic push rods 8 to move the top plate 7 downward, thereby driving the cutting blade 24 and the second trapezoidal block 25 to move downward simultaneously. During the downward movement of the top plate 7, the second trapezoidal block 25 will contact the first trapezoidal block 6 in advance, and when in contact, it will push the first trapezoidal block 6 along the groove 20. The cable moves towards the end of the rectangular block 5 in the 0 direction. At this time, the spring 23 gradually compresses under the action of the slider 22. When the first trapezoidal block 6 moves, it cooperates with the two arc grooves 18 to restrict and fix the cable, preventing displacement of the cutting position during cutting, avoiding inaccurate cutting length and dimensional errors, and improving cutting accuracy. After cutting, the two hydraulic push rods 8 are driven to move the top plate 7 upward. At this time, the second trapezoidal block 25 gradually separates from the first trapezoidal block 6. Under the reaction force of the compressed spring 23, the slider 22 is pushed to move in the opposite direction, thereby driving the first trapezoidal block 6 to gradually move away from the rectangular block 5. At this time, the cable can continue to be transported. After being transported to the specified length, the cutting work can be carried out again. There is no need to go through the process of manual fixing, cutting, manual unfixing and manual fixing again, which saves a lot of time and improves work efficiency.
[0027] Working Principle: During operation, the cable is pre-wound onto the side wall of the take-up roller 13. During cutting, one end of the cable passes through the middle of the two limiting rods 10, then through the middle of the two conveying rollers 9, positioning the cable between the two annular limiting grooves 15. Finally, it passes through the arc-shaped groove 18 between the rectangular block 5 and the first trapezoidal block 6. During cable conveying, the power switch of the motor 17 is turned on, driving one of the second rotating shafts 14 to rotate. This, in conjunction with the two gears 16, drives the other second rotating shaft 14 to rotate, thereby causing the two conveying rollers 9 to rotate in a counter-rotating manner, thus conveying the cable. Once the cable has been conveyed to a set distance, the two conveying rollers 9 stop rotating and cease conveying. At this point, the two hydraulic push rods 8 drive the top plate 7 downwards, which in turn drives the cutting blade 24 and the second trapezoidal block 25 downwards simultaneously. During the downward movement of the top plate 7, the second trapezoidal block 25 will contact the first trapezoidal block 6 beforehand, pushing the first trapezoidal block 6. The cable moves along the slide 20 towards one end of the rectangular block 5. At this time, the spring 23 gradually compresses under the action of the slider 22. When the first trapezoidal block 6 moves, it cooperates with the two arc grooves 18 to restrict and fix the cable, preventing displacement of the cutting position during cutting, avoiding inaccurate cutting length and dimensional errors, and improving cutting accuracy. After fixing, the top plate 7 continues to descend. At this time, the cutting blade 24 enters the two through grooves 19 to cut the cable. After cutting, the two hydraulic push rods 8 drive the top plate 7 to move upward. At this time, the second trapezoidal block 25 gradually separates from the first trapezoidal block 6. Under the reaction force of the compressed spring 23, the slider 22 is pushed to move in the opposite direction, thereby driving the first trapezoidal block 6 to gradually move away from the rectangular block 5. At this time, the cable can continue to be transported. After being transported to the specified length, the cutting work can be carried out again. There is no need to go through the process of manual fixing, cutting, manual unfixing and manual fixing again, saving a lot of time and improving work efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
