Description
Technical Field
[0001] The utility model relates to the field of cable production equipment, in particular to a self-adjustable meter-counting component in a cable printing device. Background Art
[0002] When spraying important parameter information such as cable type, specification, characteristics, and material on the cable sheath, it is necessary to accurately measure and record the running length of the cable through a meter-counting wheel before accurately spraying the parameter information at a specific position. When using the meter-counting wheel, it is necessary to ensure that the cable does not slip on the meter-counting wheel, and thus a meter-counting pressure wheel is used. By the pressing cooperation between the meter-counting pressure wheel and the meter-counting wheel, the friction between the cable and the meter-counting wheel is increased, thereby preventing slippage between the cable and the meter-counting wheel. The installation structure of the meter-counting pressure wheel on the market at present is as Figure 1 shown. The meter-counting pressure wheel is rotatably arranged on a hinge plate, the hinge plate is hinged to a mounting plate through a pin shaft, a tension spring shaft is arranged obliquely below the left of the hinge plate, a tension spring is arranged between the tension spring shaft and the hinge plate, a nut seat is arranged obliquely above the right of the hinge plate, a bolt is threadedly connected in the nut seat, and the bolt abuts against the hinge plate. By screwing the bolt to push the hinge plate, the hinge plate rotates upward with the meter-counting pressure wheel together after overcoming the tension of the tension spring, and a gap is left between the meter-counting pressure wheel and the meter-counting wheel. After the cable abuts against the meter-counting wheel, the pressing force of the meter-counting pressure wheel on the cable is adjusted by adjusting the bolt. Since the hinge plate and the mounting plate are connected through a pin shaft, and the meter-counting pressure wheel is eccentrically arranged on the hinge plate, the stability of the meter-counting pressure wheel is not high and it is easy to swing back and forth, which will drive the cable to swing together, thereby reducing the printing quality. Moreover, due to the limiting effect of the bolt on the hinge plate, when the meter-counting pressure wheel conveys the cable, it can only swing upward and cannot swing downward. Due to the manufacturing tolerance of the cable, it is very difficult for the cable to be completely circular. Therefore, when the part of the cable with a negative diameter tolerance passes through the meter-counting pressure wheel and the meter-counting wheel, the meter-counting pressure wheel cannot effectively press the cable, and the cable is easy to slip between the meter-counting wheel, affecting the length measurement of the meter-counting wheel and the subsequent printing work. Content of the Utility Model
[0003] The purpose of the utility model is to provide a self-adjustable meter-counting component in a cable printing device with high stability and good guiding effect.
[0004] To achieve the above object, the technical solution adopted by the present utility model is as follows: A self-adjustable metering component in a cable printing device, including a mounting plate, on which a metering wheel is rotatably arranged, a lower rubber sleeve is sleeved on the metering wheel, a metering pressure wheel is slidably arranged directly above the metering wheel, an upper rubber sleeve is sleeved on the metering pressure wheel, and the connection structure between the metering pressure wheel and the mounting plate is: A linear guide rail is vertically arranged on the mounting plate, the rail seat in the linear guide rail is fixed on the mounting plate, an adjusting seat is arranged on the slider of the linear guide rail, a mounting shaft is threadedly connected to the front side wall of the adjusting seat, the metering pressure wheel is rotatably arranged on the mounting shaft, a threaded hole is arranged on the top wall of the adjusting seat, a positioning seat is arranged on the rail seat, a through hole coaxial with the threaded hole is arranged on the positioning seat, an adjusting bolt is movably inserted through the through hole, the adjusting bolt is threadedly connected to the threaded hole on the adjusting seat, an adjusting spring is sleeved on the adjusting bolt, and when the metering pressure wheel abuts against the metering wheel, there is a gap between the inner hexagonal head of the adjusting bolt and the positioning seat.
[0005] Further, in the self-adjustable metering component in the aforementioned cable printing device, the connection structure between the metering wheel and the lower rubber sleeve is the same as the connection structure between the metering pressure wheel and the upper rubber sleeve. Taking the connection structure between the metering wheel and the lower rubber sleeve as an example: A number of first convex rings are arranged at intervals on the outer side wall of the metering wheel, a first annular groove is arranged between two adjacent first convex rings, a number of second annular grooves are arranged at intervals on the inner side wall of the lower rubber sleeve, a second convex ring is arranged between two adjacent second annular grooves, the first convex rings on the lower rubber sleeve are snapped into the second annular grooves of the metering wheel, the second convex rings on the metering wheel are snapped into the first annular grooves on the lower rubber sleeve, and there is an interference fit between the first convex ring and the second annular groove, and between the second convex ring and the first annular groove.
[0006] Further, in the self-adjustable metering component in the aforementioned cable printing device, a lead wire groove is arranged on the upper rubber sleeve, and the width of the lead wire groove is greater than the width of the lower rubber sleeve.
[0007] Further, in the self-adjustable metering component in the aforementioned cable printing device, the lead wire groove is in a V shape, and the lead wire groove is 2 - 2.5 mm wider than the lower rubber sleeve.
[0008] Further, in the self-adjustable metering component in the aforementioned cable printing device, the inner diameter of the through hole on the adjusting hole is 1 - 1.5 mm larger than the outer diameter of the adjusting bolt.
[0009] Further, in the self-adjustable metering component in the aforementioned cable printing device, the screwing direction between the mounting shaft and the adjusting seat is the same as the rotating direction of the metering pressure wheel when conveying the cable.
[0010] The advantages of the present utility model are as follows: After the length measuring pressure wheel is connected to the mounting plate through a linear guide rail, the stability of the length measuring pressure wheel is improved by the stable structure of the linear guide rail itself, preventing the situation of swinging back and forth during the conveying process, thereby improving the printing quality of the cable; the length of the adjusting bolt is set to be relatively long, so that when the length measuring pressure wheel abuts against the length measuring wheel, there is a spacing between the hexagon socket head of the adjusting bolt and the positioning seat, enabling the length measuring pressure wheel to have sufficient spacing for downward movement when clamping the cable. In this way, when the part of the cable with a negative diameter tolerance passes through the length measuring wheel and the length measuring pressure wheel, the length measuring pressure wheel will be finely adjusted downward under its own weight and the action of the adjusting spring to abut against the cable, so that it is not easy to occur the situation that the pressing force of the length measuring pressure wheel on the cable is reduced due to the cable having a negative diameter tolerance, resulting in the cable slipping on the length measuring wheel, thereby ensuring the guiding and length measuring work of the cable and further improving the printing quality of the cable.

[0012] Figure 2 is a schematic structural diagram of the self-adjusting pressure length measuring assembly in the cable printing device of the present utility model.

[0014] The following further illustrates the technical solutions of the present utility model in conjunction with the attached drawings and preferred embodiments.
[0015] As Figure 2 , Figure 3 shown, the self-adjusting pressure length measuring assembly in the cable printing device of the present utility model includes a mounting plate 1, on which a length measuring wheel 2 is rotatably arranged. The length measuring wheel 2 is a prior art. A lower rubber sleeve 21 is sleeved on the length measuring wheel 2. A length measuring pressure wheel 3 is slidably arranged directly above the length measuring wheel 2. An upper rubber sleeve 31 is sleeved on the length measuring pressure wheel 3. A V-shaped lead groove 311 is arranged on the upper rubber sleeve 31. During the process of conveying the cable, the upper rubber sleeve 31 and the lower rubber sleeve 21 cooperate to prevent the cable from being worn. The V-shaped lead groove 311 can play a good supporting role for the cable, preventing it from shaking or shifting. The lead groove 311 is 2-2.5 mm wider than the lower rubber sleeve 21. When there is no cable between the length measuring pressure wheel 3 and the length measuring wheel 2, the length measuring pressure wheel 3 will abut against the length measuring wheel 2. Since the lead groove 311 is wider than the lower rubber sleeve 21, the length measuring wheel 2 will be stuck into the lead groove 311, so as to prevent the groove wall of the lead groove 311 from being pressed and deformed after contacting the length measuring wheel 2.
[0016] The connection structure between the metering wheel 2 and the lower rubber sleeve 21 is the same as that between the metering pressure wheel 3 and the upper rubber sleeve 31. Taking the connection structure between the metering wheel 2 and the lower rubber sleeve 21 as an example: A number of first convex rings 22 are arranged at intervals on the outer side wall of the metering wheel 2, and a first annular groove 23 is arranged between two adjacent first convex rings 22. A number of second annular grooves 211 are arranged at intervals on the inner side wall of the lower rubber sleeve 21, and a second convex ring 212 is arranged between two adjacent second annular grooves 211. The second convex ring 212 on the lower rubber sleeve 21 is snapped into the first annular groove 23 of the metering wheel 2, and the first convex ring 22 on the metering wheel 2 is snapped into the second annular groove 211 on the lower rubber sleeve 21. An interference fit is provided between the first convex ring 22 and the second annular groove 211, and between the second convex ring 212 and the first annular groove 23. In this way, the connection strength between the lower rubber sleeve 21 and the metering wheel 2 can be improved, and slippage between the metering wheel 2 and the lower rubber sleeve 21 can be prevented.
[0017] The connection structure between the metering pressure wheel 3 and the mounting plate 1 is as follows: A linear guide rail 4 is vertically arranged on the mounting plate 1. The track seat 41 of the linear guide rail 4 is connected to the mounting plate 1 by a countersunk head bolt. An adjusting seat 5 is bolted to the slider 42 of the linear guide rail 4. A mounting shaft 51 is threadedly connected to the front side wall of the adjusting seat 5. The metering pressure wheel 3 is rotatably arranged on the mounting shaft 51. The screwing direction between the mounting shaft 51 and the adjusting seat 5 is the same as the rotation direction of the metering pressure wheel 3 when conveying the cable, which can prevent loosening between the mounting shaft 51 and the adjusting seat 5. A threaded hole 52 is arranged on the top wall of the adjusting seat 5, a positioning seat 43 is arranged on the track seat 41, and a through hole 431 is arranged on the positioning seat 43. The through hole 431 and the threaded hole 52 on the adjusting seat 5 are coaxially aligned vertically. An adjusting bolt 6 is movably inserted through the through hole 431. The inner diameter of the through hole 431 is 1 - 1.5 mm larger than the outer diameter of the adjusting bolt 6, facilitating the movement of the adjusting bolt 6 in the through hole 431. The adjusting bolt 6 is threadedly connected to the threaded hole 52 on the adjusting seat 5. An adjusting spring 61 is sleeved on the adjusting bolt 6. When the metering pressure wheel 3 abuts against the metering wheel 2, there is a gap between the inner hexagonal head of the adjusting bolt 6 and the positioning seat 43. When a cable is clamped between the metering pressure wheel 3 and the metering wheel 2, the adjusting seat 5 will drive the adjusting bolt 6 to move upward. In this way, a larger gap is left between the inner hexagonal head of the adjusting bolt 6 and the positioning seat 43, enabling the metering pressure wheel 3 to have sufficient spacing to move downward.
[0018] During use, pull up the adjusting bolt 6 upward. Drive the adjusting seat 5 and the length measuring pressure wheel 3 to rise together through the slider 42. Then place the cable on the lower rubber sleeve 211 of the length measuring wheel 2. Then loosen the adjusting bolt 6. The length measuring pressure wheel 3 presses against the cable under the action of its own weight and the elastic force of the adjusting spring 61. Then screw the adjusting bolt 6 to make the adjusting seat 5 and the length measuring pressure wheel 3 slowly rise together with the slider 42 until the upper and lower ends of the adjusting spring respectively abut against the positioning seat 43 and the adjusting seat 5, and the adjusting seat 5 applies an extrusion force to the adjusting spring 61. At this time, after the adjusting spring 61 is compressed, it applies a reaction force to the adjusting seat 5, thereby playing a tensioning and buffering role for the length measuring pressure wheel 3. During the conveying process of the cable, since the length measuring pressure wheel 3 is connected to the linear guide rail 4, and the linear guide rail 4 itself is a stable structure, the stability of the length measuring pressure wheel 3 installed on the mounting plate 1 can be improved, and the length measuring pressure wheel 3 will not swing back and forth during the conveying of the cable. Since the diameter and shape of the cable will have certain deviations due to manufacturing tolerances during the production process, that is to say, it is very difficult for the cable to be completely circular. Only through reasonable design and manufacturing processes can the shape of the cable be made closer to a circle as much as possible. When the part of the cable with a negative diameter tolerance passes through the length measuring wheel 2 and the length measuring pressure wheel 3, the length measuring pressure wheel 3 will be adjusted downward under its own weight and the action of the adjusting spring 61 to abut against the cable, so that it is not easy to occur the situation that the cable slips on the length measuring wheel 2 due to the reduction of the pressing force of the length measuring pressure wheel 3 on the cable caused by the cable being in a negative diameter tolerance. When the part of the cable with a positive diameter tolerance passes through the length measuring wheel 2 and the length measuring pressure wheel 3, the length measuring pressure wheel 3 will be adjusted upward under the pushing action of the cable to abut against the cable, so as to prevent the cable from being crushed, thereby improving the guiding effect on the cable.
