Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a cutting device with a protection function. Background Technique

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single-strand or multi-strand wires and insulating layers, and are used to connect circuits, electrical appliances, etc.

[0003] Patent (CN202320525690.7) discloses a wire and cable cutting device, including a bottom plate and a pair of sliders. The pair of sliders are symmetrically arranged on the top of the bottom plate. Fixing blocks are fixedly connected to the tops of the pair of sliders, and clamping components are arranged on both sides of the fixing blocks; the clamping component includes a fixing frame fixedly connected to the side surface of the fixing block, a positioning plate is fixedly connected to the outside of the fixing frame, and an electric push rod is fixedly connected to the side surface of the positioning plate. The structure of the utility model is reasonable. By starting multiple electric push rods respectively, the multiple electric push rods drive the corresponding limit blocks to cooperate with the corresponding arc grooves to squeeze and limit the cable, which is convenient for limiting cables with different thicknesses. The double-shaft motor drives two screws to rotate, and the two screws drive the two sliders to slide in opposite directions respectively to straighten the cable, which can effectively prevent the cable from often bending and deforming during the cutting process and affecting the actual cutting length.

[0004] The device in the above patent document only fixes and limits the cable, but does not consider that when the device works for a long time, cable residues will accumulate on the workbench, and some cable residues on the workbench will accumulate on the blade surface, increasing the friction during cutting, resulting in overheating of the blade. The overheated blade may lead to a decrease in cutting efficiency, serious damage to the cable surface, and even endanger the safety of the cutting machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cutting device with a protection function to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions: a cutting device with a protective function, including a workbench, above which a protective cover is movably arranged. One side of the bottom end of the protective cover is provided with a cleaning mechanism for cleaning the surface of the workbench. Inside the protective cover, a cutting machine is fixedly connected. On the left and right sides of the protective cover, a clamping mechanism for fixing the cable is arranged. The cleaning mechanism includes sliding rails opened on the front and rear sides of the top end of the workbench. The two sliding rails are located below the protective cover. Inside the two sliding rails, a moving block is arranged. At the four corners inside the moving block, pulleys are rotatably connected. The surfaces of the four pulleys are in rolling connection with the sliding rails. The top end of the moving block is rotatably connected with a connecting rod. The end of the connecting rod far from the moving block is rotatably connected with the bottom end of the protective cover. On the side where the two moving blocks are close to each other, a cleaning brush is fixedly connected.

[0007] Further, the clamping mechanism includes fixed rods fixedly connected to the left and right sides of the protective cover. On both sides of the bottom end of the fixed rod, second springs are fixedly connected. The bottom end of the second spring is fixedly connected with a contact block. Inside the second spring, a guiding column is sleeved. The bottom end of the guiding column is fixedly connected with the contact block. The surface of the guiding column is in sliding connection with the fixed rod.

[0008] Further, a drawer is arranged at the bottom end of the workbench. At the four corners of the protective cover, guiding rods are respectively slidably connected through holes. The ends of the four guiding rods far from the protective cover are fixedly connected with the workbench. A first spring is sleeved on the surface of the guiding rod. The upper and lower ends of the first spring are respectively fixedly connected with the protective cover and the workbench.

[0009] Further, a support frame is arranged at the rear side of the protective cover. The bottom end of the support frame is fixedly connected with the workbench. Inside the support frame, a pressing rod is rotatably connected. On the surface of the end of the pressing rod far from the support frame, a pushing rod is rotatably connected. The end of the pushing rod far from the pressing rod is rotatably connected with the protective cover.

[0010] Further, a cutting groove is opened at the middle position of the top end of the workbench. On the left and right sides of the cutting groove, a pouring groove and rollers are arranged. The cutting groove and the pouring groove completely penetrate the workbench and are connected to the drawer.

[0011] Further, the cutting machine is located directly above the cutting groove.

[0012] Compared with the prior art, the beneficial effects achieved by the present utility model are:

[0013] 1. The utility model is provided with a cleaning mechanism. When the staff presses down the protective cover and the first spring lifts the protective cover under the action of restoring deformation, the protective cover will give a downward force and an upward force to the connecting rod. Since the upper and lower ends of the connecting rod are respectively rotatably connected to the protective cover and the moving block and the initial state of the connecting rod is inclined, the moving block will receive a lateral force, so that the moving block moves inside the slide rail, and then drives the cleaning brush to clean the cable residues on the workbench.

[0014] 2. When the protective cover of the utility model descends, it drives the clamping mechanism to move downward. When it descends to a certain extent, the contact block will contact the cable to fix the cable to the workbench, ensuring that the cable will not roll during the cutting of the cutting machine, ensuring the flatness of the cable cutting surface, and improving the quality of cable cutting.

Detailed Embodiments

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 shown, the cutting device with a protection function includes a workbench 1. A protective cover 3 is movably arranged above the workbench 1. One side of the bottom end of the protective cover 3 is provided with a cleaning mechanism 6 for cleaning the surface of the workbench 1. A cutting machine 7 is fixedly connected inside the protective cover 3. Clamping mechanisms 8 for fixing cables are arranged on the left and right sides of the protective cover 3. A drawer 2 is arranged at the bottom end of the workbench 1. Four corners of the protective cover 3 are respectively slidably connected with guide rods 4 through holes. One ends of the four guide rods 4 far away from the protective cover 3 are fixedly connected with the workbench 1. A first spring 5 is sleeved on the surface of the guide rod 4. The upper and lower ends of the first spring 5 are respectively fixedly connected with the protective cover 3 and the workbench 1. A support frame 9 is arranged at the rear side of the protective cover 3. The bottom end of the support frame 9 is fixedly connected with the workbench 1. A pressing rod 10 is rotatably connected inside the support frame 9. One end surface of the pressing rod 10 far away from the support frame 9 is rotatably connected with a push rod 11. One end of the push rod 11 far away from the pressing rod 10 is rotatably connected with the protective cover 3. A cutting groove 12 is formed at the middle position of the top end of the workbench 1. Pouring grooves 13 and rollers 14 are arranged on the left and right sides of the cutting groove 12. The cutting groove 12 and the pouring grooves 13 completely penetrate the workbench 1 and are communicated with the drawer 2. The cutting machine 7 is located directly above the cutting groove 12.

[0024] The connection combination of the support frame 9, the pressing rod 10, the push rod 11 and the protective cover 3 is similar to the movement principle of a manual water pump in real life. The function of the protective cover 3 can prevent the splashing of cable residues during cutting and the potential safety hazards caused by the exposure of the blade of the cutting machine 7. The design of the two rollers 14 is to reduce the friction when the cable moves on the workbench 1, facilitating the staff to move the cable. The design that the cutting groove 12 and the pouring grooves 13 completely penetrate the workbench 1 and are communicated with the drawer 2 is to allow the cable residues to enter the drawer 2. When the staff cleans the cable residues, they only need to pull out the drawer 2 and pour out the cable residues in the drawer 2.

[0025] As Figures 2 - 4The cutting device with a protection function shown in the figure, the cleaning mechanism 6 includes slide rails 60 opened on the front and rear sides of the top end of the workbench 1. The two slide rails 60 are located below the protective cover 3. A moving block 61 is arranged inside the two slide rails 60. Pulley 62 is rotatably connected to each of the four corners inside the moving block 61. The surfaces of the four pulleys 62 are in rolling connection with the slide rails 60. A connecting rod 63 is rotatably connected to the top end of the moving block 61. One end of the connecting rod 63 away from the moving block 61 is rotatably connected to the bottom end of the protective cover 3. A cleaning brush 64 is fixedly connected to one side of the two moving blocks 61 close to each other. The initial state of the connecting rod 63 is inclined. The inclined state is set so that the moving block 61 moves in the slide rail 60, and the cleaning brush 64 is in frictional connection with the workbench 1.

[0026] When the staff presses down the protective cover 3 and the first spring 5 lifts the protective cover 3 under the action of restoring deformation, the protective cover 3 will give a downward force and an upward force to the connecting rod 63. Since the upper and lower ends of the connecting rod 63 are respectively rotatably connected to the protective cover 3 and the moving block 61 and the initial state of the connecting rod 63 is inclined, the moving block 61 will receive a lateral force, so that the moving block 61 moves inside the slide rail 60, and then drives the cleaning brush 64 to clean the cable residues on the workbench 1.

[0027] As Figure 5 The cutting device with a protection function shown in the figure, the clamping mechanism 8 includes fixed rods 80 fixedly connected to the left and right sides of the protective cover 3. Second springs 81 are fixedly connected to both sides of the bottom ends of the fixed rods 80. A contact block 82 is fixedly connected to the bottom ends of the second springs 81. A guide post 83 is sleeved inside the second spring 81. The bottom end of the guide post 83 is fixedly connected to the contact block 82. The surface of the guide post 83 is in sliding connection with the fixed rod 80.

[0028] When the protective cover 3 descends, it drives the clamping mechanism 8 to move downward. When it descends to a certain extent, the contact block 82 will contact the cable, fixing the cable to the workbench 1, ensuring that the cable will not roll during the cutting by the cutting machine 7, ensuring the flatness of the cable cutting surface, and improving the quality of cable cutting.

[0029] Working principle of the utility model: When the device is started, the cutting machine 7 starts. The operator holds the pressing rod 10 and presses it downwards. At this time, the pressing rod 10 drives the pushing rod 11 to move downwards, and the pushing rod 11 drives the protective cover 3 to move downwards. While the protective cover 3 deforms the first spring 5, the protective cover 3 gives a downward force to the connecting rod 63. When the operator releases the pressing rod 10, under the action of the first spring 5 restoring deformation, the protective cover 3 is pushed upwards. At this time, under the drive of the protective cover 3, an upward force is given to the connecting rod 63. The upper and lower ends of the connecting rod 63 are respectively rotatably connected to the protective cover 3 and the moving block 61, and the initial state of the connecting rod 63 is inclined. Therefore, the moving block 61 receives a lateral force, so that the moving block 61 moves inside the slide rail 60, and then drives the cleaning brush 64 to move the cable residues on the workbench 1 to the opening of the pouring groove 13. The cable residues then enter the drawer 2 through the pouring groove 13, realizing the cleaning and collection of the cable residues. At the same time, when the protective cover 3 descends to a certain extent, the contact block 82 contacts the surface of the cable, fixing the cable to the workbench 1, ensuring that the cable will not roll during the cutting by the cutting machine 7, ensuring the flatness of the cable cutting surface, and improving the quality of cable cutting.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
