Description

Technical Field

[0001] This invention relates to the field of cable cutting technology, and more specifically, to a cable cutting device that facilitates length measurement. Background Technology

[0002] Cables are made of one or more mutually insulated conductors encased in insulation and protective layers, and are wires that transmit electricity or information from one place to another. In a broad sense, they refer to devices that use metal as a medium to transmit electrical signals. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry, and shipbuilding industry, the demand for wires and cables will also grow rapidly.

[0003] When cutting cables, first, set the corresponding parameters on the control panel of the automatic wire cutter according to the required cable length and quantity, such as the cutting length and quantity; then, install the cable to be cut onto the feeding device, ensuring that the cable can smoothly enter the cutting area through the feeding device; start the automatic wire cutter, the feeding device starts working, and smoothly feeds the cable into the cutting area at the set speed, finally completing the cutting work.

[0004] Because the upper and lower blades are staggered, they cut the cable using shearing force. Therefore, a groove needs to be reserved on the cutting area of ​​the support plate to receive the upper and lower blades. When the upper blade moves upward to cut, it applies an upward force to the cable, causing upward deformation on that side. This deformation not only affects the smoothness of the cut (resulting in burrs, tears, etc.), but also, after cutting, when the cable is fed again, the uneven cut, combined with the groove, makes it easy for the cut end of the cable to press against the notch on the support plate, hindering normal cable feeding and causing a disruption in the feeding process. Summary of the Invention

[0005] The present invention provides a cable cutting device that facilitates length measurement. It uses a push rod to move down to drive a lever to extend a stop plate toward the cutting area, thereby solving the problem mentioned in the background art, namely: the cable deforms at the feeding end, affecting the flatness of the cut.

[0006] To achieve the above objectives, the cable cutting device for easy length measurement includes a base plate, a cutting head, a feeding plate, a receiving plate, and a cable feeding device for feeding cables to the cutting area. The feeding end is located on one side of the slot, and the discharging end is on the other side. A pushing mechanism and a flipping mechanism are provided on the receiving plate at the feeding end. The flipping mechanism includes a flipping part rotatably mounted with the receiving plate and a stop plate movably mounted on the flipping part. The flipping part is connected to a driving device on the receiving plate. When the cable is cut, the flipping part rotates with the power provided by the driving device, causing the cable to exert a pushing force on the pushing mechanism. The pushing mechanism then pushes the stop plate to extend towards the cutting area, obstructing the deformation of the cable at the cut. After cutting, the cable near the slot is pushed upwards, allowing the cable cut to pass over the slot.

[0007] Based on the above, the pushing mechanism includes a push rod that is movably arranged on the receiving plate in the longitudinal direction. A partition is provided on the push rod, and a compression spring is elastically fixed between the partition and the receiving plate. A push plate for lifting the cable is provided at the top of the push rod.

[0008] An inner groove is provided on the receiving plate to accommodate the push plate. When the push plate is embedded in the inner groove, the top of the push plate is flush with the upper surface of the receiving plate.

[0009] The pushing mechanism also includes a lever that is laterally slidable in the middle of the receiving plate, and the bottom of the lever is provided with a protrusion.

[0010] When the push rod moves down, the bottom of the push rod is bent, and the bent part contacts the protrusion. The lever is L-shaped and is used to move the stop plate.

[0011] The flipping part includes a rotating rod disposed on the receiving plate and a flipping plate located at the end of the rotating rod. A support is rotatably disposed at the end of the rotating rod away from the flipping plate. The support is fixed on the receiving plate. The end of the rotating rod is connected to a driving device.

[0012] The stop plate passes through the flip plate, and a tension spring elastically connects the stop plate and the flip plate.

[0013] The end of the stop plate away from the flip plate is the cable stop end, which is used to limit cable bending.

[0014] The two sides of the stop plate form a gap to accommodate the lever.

[0015] The flip plate has a notch wider than the cable, and the width of the flip plate is smaller than the width of the notch.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this cable cutting device that facilitates length measurement, the push rod moves downward to drive the lever to extend the stop plate towards the cutting area, so that the stop plate intercepts the deformed cable at the cut and flattens the cable at the same time, ensuring that the cable remains stable during cutting, thereby improving the flatness of the cut.

[0018] 2. In this cable cutting device that facilitates length measurement, the push rod moves upward under the elastic action of the compression spring to push the cable out, thereby raising the height of the cable end at the feed end slot. When the cable is conveyed again, it can smoothly pass over the slot, preventing the cable cut from sticking to the slot and affecting the further conveying of the cable. Attached Figure Description

[0030] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] Therefore, to address the problem of uneven cuts during cable cutting, this invention provides a cable cutting device that facilitates length measurement. (Refer to...) Figure 1 As shown, it includes a base plate 100, a cutting head 101, a feeding plate 102, a receiving plate 103, and a cable feeding device 104 for feeding cables to the cutting area, wherein... Figure 2 The middle arrow Q1 indicates the cutting position. A control panel is also provided on the base plate 100. Therefore, when cutting the cable, first, according to the required cable length and the number of cuts, set the corresponding parameters on the control panel of the automatic wire cutter (such as the number of cuts, or measure by the scale line on the base plate 100; the position of the cutting head 101 is the cable cutting point. Align the end of the cable with the zero point of the scale line, and then cut). Start the equipment, and the wire feeding device 104 will transport the cable to be cut to the receiving plate 103, and smoothly feed the cable into the cutting area at the set speed to ensure that the cable can pass through the cutting area smoothly before proceeding with the next cutting work.

[0032] Figure 2 In the initial state of the equipment, when the cable is fed onto the receiving plate 103, the cable end is manually pushed over the slot on the receiving plate 103 to prevent it from entering the slot. When the cable feeding stops, the cable is cut by moving the upper and lower cutting blades 101 towards the cable until it is cut. During this process, one side of the slot is the feeding end and the other side is the discharging end. The receiving plate 103 at the feeding end is equipped with a pushing mechanism 110 and a flipping mechanism 120. The flipping mechanism 120 includes components that rotate with the receiving plate 103. The rotating part and the stop plate 121 movably mounted on the rotating part are connected to the drive device on the receiving plate 103. When the cable is cut, the rotating part is powered to rotate by the drive device (e.g., a motor, which transmits power through a gear set), causing the cable to exert a pushing force on the pushing mechanism 110. The pushing mechanism 110 is used to push the stop plate 121 to extend towards the cutting area, thereby obstructing the deformation of the cable at the cut. After the cutting is completed, the cable near the slot is pushed upward, so that the cut of the cable passes through the slot. Specifically, as follows:

[0033] First, combined Figure 2 , Figure 3As shown, the pushing mechanism 110 includes a push rod 111 movably disposed on the receiving plate 103 in the longitudinal direction. A partition 114 is disposed on the push rod 111, and a compression spring 115 is elastically fixed between the partition 114 and the receiving plate 103. In the initial state, the push rod 111 is in a... Figure 3 As shown, the top of the push rod 111 is provided with a push plate 113 for lifting the cable; that is, when the cable is being cut, the cable on the push plate 113 is subjected to the rotation of the stop plate 121, and the stop plate 121 applies pressure to the cable, causing the push plate 113 to move downward against the elastic potential energy of the compression spring 115; at this time, an inner groove for accommodating the push plate 113 is provided on the receiving plate 103, and the push plate 113, which is being squeezed, is embedded in the inner groove, with the top of the push plate 113 flush with the upper surface of the receiving plate 103.

[0034] It should be noted that: before the cable is cut, the cable is manually pulled out from the top push plate 113 and passed through the slot. Figure 3 The image shows the state of the cable before it was cut.

[0035] Next, let's return to... Figure 2 As shown, the pushing mechanism 110 also includes a lever 112 that is laterally slidable in the middle of the receiving plate 103, and a protrusion 116 is provided at the bottom of the lever 112 (see reference). Figure 3 As shown), when the push rod 111 moves downward, the bottom of the push rod 111 is bent, and the bent part contacts the protrusion 116. The lever 112 is L-shaped and is used to move the stop plate 121. That is, when the stop plate 121 rotates to apply pressure to the cable, the lifted cable and the push plate 113 move downward, while the bent part of the push rod 111 applies pressure to the compression spring 115. At this time, since the lever 112 is slidably set with the receiving plate 103 in the lateral direction, therefore, in Figure 2 Based on and combined Figure 6 As shown, the push rod 111 applies pressure to the protrusion 116, causing the lever 112 to move along... Figure 2 The center arrow slides to one side, thereby providing power for the lateral movement of the drive lever 112;

[0036] As the height of the push plate 113 decreases until it is inserted into the inner groove, the cable is laid flat on the receiving plate 103, and the upper and lower cutting heads 101 complete the cutting work.

[0037] It should also be understood that the flipping part includes a rotating rod 122 mounted on the receiving plate 103, and a flipping plate 123 located at the end of the rotating rod 122. A support 105 is rotatably mounted at the end of the rotating rod 122 away from the flipping plate 123. The support 105 is fixed to the receiving plate 103. The end of the rotating rod 122 is connected to a drive device. This drive device is existing technology and only provides a power source for the rotation of the rotating rod 122, and is not described in detail. Next, a stop plate 121 passes through the flipping plate 123, and a tension spring 124 is elastically connected between the stop plate 121 and the flipping plate 123. Figure 3 The image shows the state of the stop plate 121 and the tension spring 124. The end of the stop plate 121 is located inside the flip plate 123, and the tension spring 124 is in a stretched state. The end of the stop plate 121 away from the flip plate 123 is the wire-stopping end, which is used to limit the bending of the cable to ensure that the cable is transported flat to the cutting area.

[0038] In other words, when the cable stops being delivered, the drive unit rotates the rotating rod 122 along the connection point between it and the support 105. Figure 3 The rotation direction of the rotating rod 122 is shown below. As the rotation amplitude increases, when the push plate 113 moves downward, the lever 112 moves the stop plate 121 towards the cutting area, as shown below:

[0039] Working principle: Combining Figure 4 As shown, gaps 125 are formed on both sides of the stop plate 121 to accommodate the lever 112. Then, returning to... Figure 3 As shown, during the rotation of the stop plate 121, the lever 112 overcomes the elastic potential energy of the tension spring 124 by moving laterally, thereby causing the stop plate 121 to extend towards the cutting area. That is, the rotating rod 122 rotates to... Figure 5 In the state shown, the end of the stop plate 121 extends out from the flip plate 123, and the stop plate 121 extends toward the slot and approaches the cutting head 101. In this way, when the lower cutting head 101 cuts the cable upward, the extended stop plate 121 can counteract the upward deformation of the cable, thereby improving the flatness of the cable cut.

[0040] Furthermore, the stop plate 121, which is flipped to a horizontal position, can also work with the push plate 113 to clamp the cable. That is, the push plate 113 applies an upward pushing force to the cable under the elastic action of the compression spring 115, while the stop plate 121 applies downward pressure to the cable. In this way, the cable can be clamped and fixed.

[0041] Furthermore, to ensure that the stop plate 121 contacts the cable, refer to... Figure 6As shown, a notch 126 wider than the cable is provided on the flip plate 123, and the width of the flip plate 123 is smaller than the width of the notch (specifically, L1 is the width of the notch 126, L2 is the width of the notch, and L3 is the width of the flip plate 123). Thus, the stop plate 121 is in a position... Figure 5 When in the correct position, the end of the flip plate 123 can rotate into the slot. At the same time, the cable is located at the notch 126 and contacts the stop plate 121. The stop plate 121 flattens the cable to prevent wrinkles from forming.

[0042] Then, after the cable is cut, the rotating rod 122 rotates in the opposite direction to reset. During this process, under the elastic action of the tension spring 124, the stop plate 121 moves in the opposite direction. At the same time, the stop plate 121 pushes the lever 112 to move in the opposite direction. Under the elastic action of the compression spring 115, the push rod 111 moves upward to push the cable out, so that the height of the cable end at the feed end slot is raised. When the cable is conveyed again, it can pass smoothly over the slot, preventing the cut end of the cable from sticking to the slot and affecting the further conveying of the cable.

[0043] It should be noted that although the pushed-out cable is bent, the flat cable itself has a certain degree of rigidity, and the height of the push plate 113 is not too high, so that the cable will not be easily bent during the transportation process and affect the transportation progress.

[0044] Therefore, in summary, the push rod 111 moves downward to drive the lever 112 to extend the stop plate 121 towards the cutting area, so that the stop plate 121 intercepts the deformed cable at the cut and flattens the cable at the same time, ensuring that the cable remains stable during cutting, thereby improving the flatness of the cut.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
