[0001] The utility model relates to the technical field of steel cord detection, in particular to a steel cord door mold alarm. Background Art

[0002] Steel cord is composed of two or more steel wires, or a combination of strands or a combination of strands and wires. Steel cords are made through processes such as drawing, heat treatment, and stranding. After stranding, the steel cords may break or bulge, causing abnormal diameter of the steel cords, which in turn reduces their strength and affects product quality.

[0003] For example, patent publication number CN219137256U discloses a wire breakage detection device for steel cords. Its principle is: when the steel cord is bent, broken, or bulged, the steel cord will drive the detection piece to lift up, thereby driving the door mold to lift up. Since the lower end of the first detection column is fixed to the door mold, the first detection column is lifted up, and the first armature and the second armature are in contact, forming a closed loop, and the alarm device is turned on and an alarm is generated. It can detect abnormal diameters of steel cords, but the overall structure is relatively complex, and the alarm action process is relatively cumbersome. Summary of the invention

[0004] In order to solve the problems of complex structure and cumbersome detection operation process of conventional steel cord broken wire detection devices, the utility model provides a steel cord door mold alarm, in which a door mold is rotatably arranged on one side of the door mold. When the steel cord passes through the door mold, once the diameter is abnormal, the door mold will be driven to flip. The flipped door mold is equivalent to a switch, which can realize the circuit conduction of the alarm unit, thereby generating an alarm.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A steel cord door mold alarm, used for detecting abnormal steel cord diameter, comprising a mounting seat, a door mold and an alarm unit, wherein the door mold is arranged on the mounting seat, and the door mold comprises a door mold body, a door mold hole and a door mold plate, wherein the door mold body is provided with the door mold hole for the steel cord to pass through, and the door mold plate is arranged on one side of the door mold body in a rotation manner, and the upper end of the door mold plate extends upward into the door mold hole, and if the steel cord diameter is abnormal, the steel cord will touch the door mold plate in the process of passing through the door mold hole, and the rotation direction of the door mold plate is consistent with the axial direction of the door mold hole;

[0007] The alarm unit includes a terminal, a conductive sheet and an alarm. The terminal is also arranged on a mounting seat, and the conductive sheet is arranged on a door template. The door template and the terminal are staggered up and down. The flipped door template drives the conductive sheet to contact the terminal. The door template is equivalent to a switch. A wire is connected between the terminal and the conductive sheet. The door template facilitates the conduction and closure of the wire. A power supply and an alarm are connected in series on the wire. After the wire is turned on, the alarm operates.

[0008] Furthermore, the mounting base includes a mounting plate and a support plate. The mounting plate is bent into an "L" shape. A mounting hole is opened at one end of the mounting plate. The mounting holes are waist-shaped holes and there are two of them. The mounting base can be connected and fixed to the housing of the equipment by passing bolts through the mounting holes, and the mounting position of the mounting base can be flexibly adjusted up and down. The other end of the mounting plate is bolted to the door mold body to facilitate the disassembly and assembly of the door mold body. The support plate is also set at the other end of the mounting plate, and the terminal is set on the support plate.

[0009] Furthermore, the door mold body is arranged vertically, the door mold hole passes through the door mold body, the door mold hole is located higher than the mounting seat to prevent the mounting seat from touching the running steel cord, and the door mold hole and the door mold plate are arranged up and down.

[0010] Furthermore, the door template includes a platform stage and a cylindrical section integrally formed at the top and bottom. The door template is narrow at the top and wide at the bottom. A pin is provided between the cylindrical section and the door template body for rotational connection. There is an eccentricity between the pin and the cylindrical section to ensure the stability of the vertical state of the door template.

[0011] The stage is located at one end of the door mold hole, and extends upward to within the circular cross-section of the door mold hole. The axial direction of the door mold hole is perpendicular to the axial direction of the pin shaft.

[0012] Furthermore, the terminal includes a stepped insulating sleeve, an insulating pad, a flat pad, a magnet ring with a hole, a copper screw and a copper nut. The insulating sleeve is passed through the support plate, and the magnet ring is arranged above the insulating sleeve. The copper screw passes downward through the magnet ring and the insulating sleeve in sequence and is connected to the copper nut, thereby fixing the copper screw. The insulating pad and the flat pad are sleeved on the copper screw between the copper nut and the support plate, and the insulating pad contacts the support plate. The copper screw located below the support plate is connected to the wire.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model has a reasonable structural design. A through-going door mold hole is provided on the door mold body. The door mold template is rotated on one side of the door mold body. The door mold hole and the door mold template are arranged in an up-down staggered manner, and the upper end of the door mold template extends into the circular cross section of the door mold hole. In this way, a steel cord with a normal diameter will not touch the door mold template when passing through the door mold hole. Once the diameter is abnormal, it will touch the door mold template and drive it to flip down. The door mold template is provided with a conductive sheet, which is connected to a fixed terminal through a wire. After flipping down, the door mold template will contact the terminal to realize the closure and conduction of the circuit. The alarm on the circuit is activated to warn the workers, thereby conveniently and effectively detecting the broken wire and drum wire of the steel cord.

[0015] The door template of the utility model is equivalent to a switch. When the door template is flipped down, the switch is closed and the line conduction alarm is activated; when the door template is in a normal vertical state, the switch is open and the line disconnection alarm does not work. The entire door template alarm has a simple structure and a simple detection operation process. It can detect steel cords with abnormal diameters in time, avoid the steel cords with abnormal diameters from continuing to run downward, and ensure the quality of the steel cords.

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0023] like Figure 1~Figure 5As shown, a steel cord door mold alarm is used to detect abnormal steel cord diameter, including a mounting base 1, a door mold 2 and an alarm unit. The mounting base 1 is used to install the alarm 8 of the entire door mold 2 and can carry the door mold 2 and the alarm unit. Figure 1 shown.

[0024] The mounting base 1 includes a mounting plate 101 and a support plate 102. The mounting plate 101 is bent into an "L" shape and arranged horizontally. One end of the mounting plate 101 is provided with a mounting hole 3. The mounting holes 3 are waist-shaped holes and there are two of them. The mounting holes 3 are arranged vertically, so that the vertical height position of the mounting base 1 can be adjusted. The support plate 102 is arranged at the other end of the mounting plate 101, and the support plate 102 is also arranged horizontally. Figure 2 shown.

[0025] The mounting seat 1 is provided with a door mold 2, which includes a door mold body 201, a door mold hole 202 and a door mold plate 203. When the door mold 2 is installed, the other end of the mounting plate 101 is bolted to the door mold body 201 to achieve the connection and fixation between the door mold 2 and the mounting seat 1. The door mold body 201 is arranged vertically, and a door mold hole 202 for the steel cord to pass through is arranged on the door mold body 201. The door mold hole 202 is arranged horizontally and passes through the door mold body 201. The cross section of the door mold hole 202 is circular, and the door mold hole 202 is located higher than the mounting seat 1 to prevent the mounting seat 1 from interfering with the running and passing of the steel cord.

[0026] The door mold body 201 is rotated to set the door mold template 203 on one side, and the door mold hole 202 and the door mold template 203 are arranged up and down, and the door mold template 203 is located at one end of the outlet line of the entire door mold hole 202. When the door mold template 203 is installed, the door mold template 203 includes a platform stage 41 and a cylindrical section 42 integrally formed up and down. The door mold template 203 is narrow at the top and wide at the bottom. A pin shaft 5 is inserted between the cylindrical section 42 and the door mold body 201. The axial direction of the door mold hole 202 is perpendicular to the axial direction of the pin shaft 5. Figure 3 The pin shaft 5 thus realizes the rotation connection of the door template 203, and the door template 203 can rotate relative to the door mold body 201, and the rotation direction of the door template 203 is consistent with the axial direction of the door mold hole 202.

[0027] The door template 203 remains vertical under normal conditions. At this time, the upper end of the door template 203 extends upward into the door mold hole 202, that is, the stage 41 extends upward to the circular cross-sectional range of the door mold hole 202. The stage 41 is located at one end of the door mold hole 202, which is equivalent to forming a partial closure on one end of the door mold hole 202 and reducing the cross-sectional area of ​​the door mold hole 202.

[0028] In order to ensure the vertical state of the door template 203, there is eccentricity between the pin shaft 5 and the cylindrical section 42, so that the door template 203 has a rotation tendency toward the door mold body 201, which can ensure the partial closure of the door mold hole 202 by the door template 203 and prevent the door template 203 from flipping downward away from the door mold hole 202.

[0029] The alarm unit includes a terminal 6, a conductive sheet 7 and an alarm 8. Figure 4 As shown. The terminal 6 is also arranged on the mounting seat 1, that is, the terminal 6 is arranged on the support plate 102. The terminal 6 includes a stepped insulating sleeve 61, an insulating pad 62, a flat pad 63, a magnet ring 64 with a hole, a copper screw 65 and a copper nut 66. The insulating sleeve 61 passes through the support plate 102 and penetrates the support plate 102. The magnet ring 64 is arranged above the insulating sleeve 61. The copper screw 65 passes through the magnet ring 64 and the insulating sleeve 61 downward in sequence and is connected to the copper nut 66. The copper screw 65 vertically penetrates the support plate 102. The insulating pad 62 and the flat pad 63 are sleeved on the copper screw 65 between the copper nut 66 and the support plate 102, and the insulating pad 62 contacts the support plate 102. Under the action of the insulating sleeve 61 and the insulating pad 62, the copper screw 65 and the copper nut 66 can be prevented from contacting the support plate 102.

[0030] The conductive sheet 7 is arranged on the door template 203. When the conductive sheet 7 is arranged, the conductive sheet 7 is installed at one end of the insulating column, and the other end of the insulating column is embedded in the side wall of the door template 203, so as to achieve insulation between the conductive sheet 7 and the door template 203. The door template 203 and the terminal 6 are arranged in an up-down staggered manner. The flipped door template 203 drives the conductive sheet 7 to contact the terminal 6, that is, to contact the top of the copper screw 65.

[0031] A wire 9 is connected between the terminal 6 and the conductive sheet 7, and a copper screw 65 located below the support plate 102 is connected to one end of the wire 9. A power source 10 and an alarm 8 are also connected in series to the wire 9. In this way, the door template 203 is equivalent to a switch. When the door template 203 is flipped down, the copper screw 65 contacts the conductive sheet 7, and then the wire 9 is closed to form a loop, and the alarm 8 is activated.

[0032] The principle of the utility model is as follows: under normal conditions, the gate template 203 remains in a vertical state, and when a steel cord of normal diameter passes through the gate mold hole 202, it will not contact the inner wall of the gate mold hole 202. Once the steel cord is broken or bulged, the diameter of the steel cord will increase. At this time, the steel cord will touch the upper end of the gate template 203 during the process of passing through the gate mold hole 202, driving the gate template 203 to turn down, and then the conductive sheet 7 contacts the copper screw 65 to realize the closing of the conductor 9, and the alarm 8 will be activated to warn the workers. Figure 5 shown.

[0033] The magnet ring 64 is a strong magnet, and its function is: when the conductive sheet 7 contacts the copper screw 65, the magnet ring 64 can reliably adsorb the door template 203 to ensure that the wire 9 is always closed. When the high-speed steel cord touches the door template 203, it will produce a certain impact force on the door template 203. If there is no magnet ring 64, the door template 203 after turning down will hit the copper screw 65 and rebound, and then the wire 9 will be intermittently conductive. The magnet ring 64 is used to adsorb the door template 203 after turning down, so as to avoid this situation.

[0034] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
