Description

Technical Field

[0001] The invention belongs to the technical field of cables, and specifically relates to stripping cable insulation, and in particular to a cable cutting device and a cutting method. Background Art

[0002] In cable processing operations, it is often necessary to cut the insulation layer on the outside of the cable. The current common cutting method is to let the cutting equipment rotate around the cable. When the insulation layer is cut, the high temperature generated by the cutting will cause a chemical reaction in the insulation layer, thereby producing toxic and harmful gases.

[0003] The cut insulation layer falls into the collection box below through the collection port. However, due to the high temperature generated by the cutting, the temperature at the insulation layer break is difficult to reduce in a short time, causing the insulation layer to continue to emit harmful gases in the collection box.

[0004] In the related art, the method of reducing the opening size of the collection port is usually adopted to deal with the leakage of harmful gases. However, when the size of the collection port is small, the cut insulating layers are very likely to be squeezed and stacked on each other during the falling process, thereby causing the collection port to be blocked. Therefore, how to prevent the insulating layer from blocking the collection port is a technical problem that needs to be solved urgently in this field.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component may be directly formed on the second component, or the third component may be interposed between the first component and the second component. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0027] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0028] Research has found that in the relevant technology, it is often necessary to cut the insulation layer outside the cable during cable processing. The current common cutting method is to let the cutting equipment rotate around the cable. When the insulation layer is cut, the high temperature generated by the cutting will cause a chemical reaction in the insulation layer, thereby producing toxic and harmful gases.

[0029] The cut insulation layer falls into the collection box below through the collection port. However, due to the high temperature generated by the cutting, the temperature at the insulation layer break is difficult to reduce in a short time, causing the insulation layer to continue to emit harmful gases in the collection box.

[0030] In the related art, the method of reducing the opening size of the collection port is usually adopted to deal with the overflow of harmful gases. However, when the size of the collection port is small, the cut insulating layers are very likely to be squeezed and stacked on each other during the falling process, thereby causing the collection port to be blocked. Once the collection port is blocked, it will not only affect the normal progress of the cutting operation and reduce work efficiency, but may also cause harmful gases to accumulate near the cutting device, posing a serious threat to the health of the operator.

[0031] Therefore, how to prevent the insulating layer from clogging the collecting port is a technical problem that urgently needs to be solved in this field.

[0032] The defects in the above solutions and the reasons for their occurrence are the results obtained by the inventor after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] like Figures 1 to 6 As shown, at least one embodiment provides a cable cutting device, including: a positioning cylinder 1, which is rotatably arranged in a cutting device 4; an outer sleeve is arranged on one side of the cutting device 4, and the positioning cylinder 1 is rotatably arranged in the outer sleeve. Further, a motor is arranged in the outer sleeve, and the positioning cylinder 1 is connected to the motor in a transmission manner. A limiting device 2 is arranged at the outer end of the positioning cylinder 1; the limiting device 2 is suitable for clamping the limiting cable, and after the end of the cable is inserted into the positioning cylinder 1, the limiting device 2 is suitable for clamping the cable to prevent it from shifting during the cutting process. A limiting cutting assembly 3 is slidably arranged on the inner wall of the positioning cylinder 1; the two cutting knives 33 of the limiting cutting assembly 3 can separate the insulating layer of the outer wall of the cable when they move toward each other, and the positioning cylinder 1 drives the limiting cutting assembly 3 to rotate synchronously when it rotates, and the cutting knives 33 are suitable for cutting off the insulating layer. Among them, the cable is inserted into the positioning cylinder 1 after passing through the limiting device 2, and the limiting cutting component 3 slides toward the cable to cut its outer insulation layer; the positioning cylinder 1 drives the limiting cutting component 3 to rotate to cut off the outer insulation layer of the cable; after the insulation layer at the bottom end of the outer wall of the cable is cut, the limiting device 2 releases the limit on the cable and pulls the cable to move outward so that the insulation layer is peeled off from the outer wall of the cable. After the cutting is completed, the limiting cutting component 3 slides in the direction away from the cable to push the cut insulation layer to fall downward. Through the cooperation of the positioning cylinder 1, the limiting cutting component 3 and the receiving groove 11 and the collecting port 12 provided on the cutting device 4, when cutting, the two cutting knives 33 move toward each other to clamp the cable, and the positioning cylinder 1 drives the cutting knives 33 to rotate to cut off the insulation layer of the outer wall of the cable; after the cutting is completed, one cutting knife 33 moves upward and is inserted into the receiving groove 11, and the cooling medium is suitable for cooling the cutting knife 33. Another cutting knife 33 moves downward and is inserted into the collecting port 12 to prevent the insulating layer from blocking the collecting port 12 after cutting, and at the same time, it can also prevent the harmful gas in the collecting box from overflowing.

[0036] Reference Figure 2The limiting cutting assembly 3 includes: a limiting ring 31, which is fixed on the inner wall of the positioning tube 1 and has a through opening 32 radially provided; the limiting ring 31 is arranged on the inner wall of one end of the positioning tube 1 close to the limiting device 2. The cable is suitable for being inserted into the interior of the positioning tube 1 after passing through the limiting ring 31. Two cutting knives 33 are arranged opposite to each other, the cutting knives 33 are slidably arranged in the through opening 32, and the outer ends thereof penetrate the positioning tube 1; a driving ring 35 is rotatably arranged on the inner wall of the limiting ring 31 and is linked with the cutting knives 33; wherein, when the driving ring 35 rotates forward, the two cutting knives 33 are driven to move toward each other to cut off the insulating layer; when the driving ring 35 rotates reversely, the two cutting knives 33 are driven to move away from each other, at which time the outer ends of the two cutting knives 33 protrude from the positioning tube 1 respectively, and one of the cutting knives 33 moves upward and is inserted into the receiving groove 11, and the cooling medium in the receiving groove 11 is suitable for cooling the cutting knives 33. The other cutting knife 33 moves downward to be inserted into the collecting port 12 to push the fallen insulating layer into the collecting port 12 to prevent the insulating layer from blocking the collecting port 12 .

[0037] Reference Figure 3 The driving ring 35 is symmetrically provided with two adjustment openings 36, which are arc-shaped, and the distance from one end of the adjustment opening 36 to the other end of the axis of the driving ring 35 gradually increases. A positioning column 34 is fixed to the side wall of the cutting blade 33, and the positioning column 34 is slidably arranged in the adjustment opening 36. When the driving ring 35 rotates forward, the two cutting blades 33 are driven to move toward each other; when the driving ring 35 rotates reversely, the two cutting blades 33 are driven to move away from each other.

[0038] Reference Figure 6, a receiving groove 11 is provided at the top wall of the cutting device 4, and a cooling medium is arranged in the receiving groove 11; the receiving groove 11 is located directly above the cutting blade 33; wherein, when the driving ring 35 rotates in the opposite direction, the two cutting blades 33 are driven to move away from each other, and the outer ends of the cutting blades 33 are suitable for being inserted into the receiving groove 11 and in contact with the cooling medium. The cooling medium is suitable for cooling the cutting blades 33. A collecting port 12 is provided at the bottom wall of the cutting device 4, and the collecting port 12 is arranged above the collecting box, and the collecting port 12 is suitable for guiding the insulating layer to fall into the collecting box. The collecting port 12 is arranged directly below the cutting blade 33; wherein, after the cutting is completed, the two cutting heads move away from each other, and the cutting blade 33 moves toward the collecting port 12 to push the insulating layer to fall toward the collecting port 12. Since the length of the insulating layer cut at the end of the cable is different, the insulating layer with a corresponding length greater than the opening size of the collecting port 12 is difficult to fall into the collecting box after being peeled off from the outer wall of the cable, and long-term accumulation at the collecting port 12 will affect the subsequent cutting of the insulating layer of the outer wall of the cable. Therefore, when the lower cutting blade 33 moves downward, the cutting blade 33 is suitable for pushing the insulating layer above the collecting port 12 to make it fall into the collecting box. Further, when the limiting cutting assembly 3 is not working, the distance between the two cutting blades 33 is the farthest, the upper cutting blade 33 is inserted into the receiving groove 11, and the lower cutting blade 33 is inserted into the collecting port 12, and the cutting port is suitable for blocking the harmful gas overflowing from the insulating layer in the collecting box to flow into the positioning cylinder 1.

The through hole 10 corresponds to the collecting hole 12, and the cut insulating layer falls into the collecting hole 12 along the through hole 10.

[0040] Reference Figure 1 The limiting device 2 includes: a driving cylinder 21, which is arranged at the outer end of the positioning tube 1; two clamping claws 22, which are hinged at the movable end of the driving cylinder 21 and are arranged opposite to each other; a positioning plate 23, which is arranged on the outer wall of the driving cylinder 21 and has a positioning groove 24 at the upper end.
