Description

Technical Field

[0001] The utility model relates to the technical field of cable cutting, in particular to a cable equidistant cutting device. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy information and realize electromagnetic energy conversion. During the processing of wires and cables, it is necessary to send samples of wires and cables for inspection. The wires and cables are cut into multiple wires and cables of the same length to facilitate the inspection of the wires and cables. Therefore, an equidistant cutting device is needed for wire and cable processing.

[0003] When cutting, it is usually necessary to manually measure the cable length and cut at a fixed distance. The measurement work after each cut is time-consuming and cannot achieve the purpose of automatic fixed-distance cutting. Therefore, we propose a cable equidistant cutting device. Utility Model Content

[0004] The purpose of the utility model is to provide a cable equidistant cutting device, which transmits the cable to the side by providing a transmission structure, so that the end of the cable is transmitted to the surface of a stop plate set at a fixed distance and triggers a travel switch to stop the transmission, thereby achieving the purpose of quickly determining the cable length, and then cutting the cable through a cutting machine, thereby achieving the purpose of efficient and fast fixed-distance cutting of the cable, and solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable equidistant cutting device, comprising a base and an upper plate, the upper plate is supported in parallel above the side edge of the base, and an opening that passes through from top to bottom is opened on the base surface away from the upper plate side; two first wheels are longitudinally rotatably installed on the base surface on the side of the opening, a guide wheel is longitudinally rotatably installed above the base between the first wheels, a hydraulic cylinder is vertically installed on the upper plate surface close to the opening side, a lifting plate is horizontally fixed to the end of the hydraulic cylinder, and a cutting machine is installed on the bottom surface of the lifting plate; an electric push rod is horizontally installed on the side surface of the base away from the first wheel, a push plate is vertically fixed to the end of the electric push rod, a travel switch is installed at the middle position of the surface of the push plate, a push plate parallel to the push plate is arranged on the side surface of the push plate, and connecting rods that pass through the other side of the push plate are connected to the four corners of the push plate surface, and a spring is sleeved on the outer ring of the connecting rod between the push plate and the push plate.

[0006] By adopting the above technical solution, the electric push rod is first used to drive the position of the push plate and the abutment plate, and the distance between the abutment plate and the cutting position is adjusted to determine the positioning length of the cable. The cable is driven to the left until it hits the surface of the abutment plate and triggers the travel switch. After the cable transportation is stopped, the cable is cut off by lowering the cutting machine.

[0007] Optionally, a stepper motor is installed on the surface of the side plate at the front end of the guide wheel, and the stepper motor is transmission-connected to the guide wheel.

[0008] By adopting the above technical solution, the guide wheel can be driven to rotate by a stepper motor so as to transport the cable to the left side.

[0009] Optionally, a second guide wheel is longitudinally rotatably installed inside the opening, and the second guide wheel is located inside the opening close to the cutting machine side.

[0010] By adopting the above technical solution, the second wheel supports the cable passing through the opening. When the cable is cut off, the cable will rotate to the left due to gravity and then slide smoothly under the base.

[0011] Optionally, a groove is longitudinally opened on the surface of the base below the cutting machine, and the groove is located directly below the cutting blade of the cutting machine.

[0012] By adopting the above technical solution, after the cutter of the cutting machine cuts the cable downward, it enters the cutting groove and avoids contact with the base.

[0013] Optionally, the upper plate is supported above the base by pillars at the four corners of its bottom, and the pillars on one side are supported above the base at the front and rear ends of the opening.

[0014] By adopting the above technical solution, horizontal support of the upper plate is achieved through the pillars at the four corners of the bottom of the upper plate.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The technical solution of the present application transmits the cable to the side by providing a transmission structure, so that the end of the cable is transmitted to the surface of the abutment plate set at a fixed distance and the travel switch is triggered to stop the transmission, thereby achieving the purpose of quickly determining the length of the cable, and then the cable is cut by a cutting machine, thereby achieving the purpose of efficient and fast fixed-distance cutting of the cable.

[0017] 2. The technical solution of the present application is to install a second wheel rotatably in the longitudinal direction only in the inner part of the opening near the cutting position, so that the cable can be easily rotated to the left after being cut, thereby facilitating its automatic sliding down.

DETAILED DESCRIPTION

[0023] See also Figure 1-3 The utility model provides a technical solution: a cable equidistant cutting device, comprising a base 1 and an upper plate 2, wherein the four corners of the bottom of the base 1 are vertically supported and fixed with legs of the same height to achieve lateral horizontal support for the base 1, and an opening 11 is opened on the left side surface of the base 1, and the opening 11 passes through the left side surface of the base 1 from top to bottom.

[0024] The upper plate 2 is placed horizontally on the upper right side of the base 1, and pillars 21 are vertically fixed at the four corners of the bottom of the upper plate 2. The two pillars 21 on the right side are vertically supported on the front and rear end surfaces of the right side of the bottom plate, and the pillars 21 on the left side are vertically supported on the bottom plate surface at the front and rear ends of the opening 11. The heights of the pillars 21 are the same, thereby realizing horizontal support for the upper plate 2.

[0025] Two first support wheels 12 are longitudinally rotatably installed on the surface of the base 1 on the right side of the opening 11, and a guide wheel 5 is longitudinally rotatably installed on the upper part of the base 1 between the first support wheels 12. The outer circles of the first support wheels 12 and the guide wheel 5 are surrounded by an annular groove body, so that the cable can be placed on the outer circle of the annular groove body between the upper guide wheel 5 and the lower first support wheel 12, so as to realize the guiding support of the cable. A stepper motor 51 is installed on the side plate surface at the front end of the guide wheel 5, and the stepper motor 51 is connected to the guide wheel 5. The stepper motor 51 can be used to drive the guide wheel 5 to rotate, thereby driving the cable to move slowly to the left.

[0026] When the lifting lever 31 is in the unlocking state, the lifting lever 31 is in the unlocking state, and ...

[0027] A hydraulic cylinder 4 is vertically installed on the left surface of the upper plate 2, and the lower part of the hydraulic cylinder 4 passes through to the lower part of the upper plate 2. A lifting plate 41 is horizontally fixed to the end of the hydraulic cylinder 4, and a cutting machine 411 is installed on the bottom surface of the lifting plate 41. A cutting groove 15 is longitudinally opened on the surface of the base 1 below the cutting machine 411. The cutting groove 15 is located directly below the cutting knife of the cutting machine 411. When the cable is transmitted at a fixed distance, the cutting machine 411 rotates and is driven to lower its height, so that the cable can be cut at a fixed distance in cooperation with the cutting groove 15.

[0028] A second support wheel 13 is longitudinally rotatably installed inside the opening 11, and the second guide wheel 5 is located inside the opening 11 close to the cutting machine 411, so that the second guide wheel 5 will support and resist the right side of the center of gravity of the cable after cutting. After the cable is cut, it will deflect to the left and then slide down to achieve the purpose of automatically discharging the cable.

[0029] When in use, the cable is passed between the second support wheel 13 on the right and the guide wheel 5, and is placed in the arc groove of the two. According to the required length of the cable to be cut, the position of the push plate 3 and its surface is adjusted so that the horizontal distance between the surface of the plate 31 and the cutting groove 15 is equal to the length of the cable to be cut. The electric push rod 14, the travel switch 32, the cutting machine 411, the stepper motor 51 and the hydraulic workstation connected to the hydraulic cylinder 4 are all connected to the control device, so that the stepper motor 51 is started to drive the guide wheel 5 to rotate, and cooperate with the first support wheel 12 below to drive the cable to move to the left, and pass through the second support wheel 13 to guide and transmit it to the left until it reaches the left side. The left side of the cable hits the surface of the abutment plate 31, causing the abutment plate 31 to move to the left and release the travel switch 32. The signal is transmitted to the control device, which stops the stepper motor 51 from rotating and stops conveying the cable to the left. At the same time, the hydraulic cylinder 4 is controlled to drive the started cutter 411 to move downward, cutting the cable above the cutting groove 15. After that, the cutter 411 is driven by the hydraulic cylinder 4 to rise to a higher height. Since the second support wheel 13 is supported on the right side of the center of gravity of the cable, the cut cable will be offset and rotated to the left and slide down. The above operation can be repeated to achieve the purpose of automatically cutting the cable at a fixed distance.
