Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machine protection devices, in particular to a wire drawing machine annealing wheel carbon brush holder protection device. Background Art

[0002] At present, wire drawing machine is an important equipment for producing cable metal wire, which is mainly used for two processes: wire drawing and annealing. Wire drawing refers to turning coarse materials into thin wires through pulling force, while annealing refers to heating the material to a certain temperature and then slowly cooling it to change its organizational structure and properties.

[0003] Chinese patent CN201296771Y discloses a continuous annealing wire drawing machine electrode guide wheel cooling device, including a copper guide wheel and a carbon brush. The carbon brush is installed on a carbon brush holder. During the annealing process, the copper guide wheel is in a high-speed rotation state, and friction will be generated between the carbon brush and the high-speed rotating copper guide wheel. Therefore, the carbon brush is a consumable and needs to be replaced in time.

[0004] However, the operator cannot observe the wear of the carbon brushes in real time, and the carbon brushes may not be replaced in time, resulting in excessive wear of the carbon brushes, causing direct friction between the metal part of the carbon brush holder and the copper guide wheel, causing the carbon brush holder to overheat. At the same time, since there will inevitably be carbon powder residue on the carbon brush holder caused by the wear of the carbon brushes, there is a risk of fire. Utility Model Content

[0009] The non-contact temperature measurement component is arranged on the side of the carbon brush holder, and the non-contact temperature measurement component is used to monitor the temperature of the carbon brush holder;

[0010] The alarm is electrically connected to the non-contact temperature measurement component, and when the non-contact temperature measurement component detects that the temperature of the carbon brush holder is greater than a calibrated temperature, the alarm issues a warning.

[0011] Based on the above technical solution, preferably, the non-contact temperature measurement component includes a non-contact temperature sensor and a bracket, the bracket is fixed to the side of the carbon brush holder, the non-contact temperature sensor is installed on the bracket, and the non-contact temperature sensor is arranged toward the carbon brush holder.

[0012] On the basis of the above technical solution, preferably, the non-contact temperature sensor is an ultrasonic temperature sensor.

[0013] On the basis of the above technical solution, preferably, the non-contact temperature measurement component includes a first control circuit, and the first control circuit includes an alarm switch SB1 and a contactor KM1;

[0015] Based on the above technical solution, preferably, when the non-contact temperature measurement component detects that the temperature of the carbon brush holder is greater than the calibration temperature, the alarm switch SB1 is connected, so that the coil of the contactor KM1 is energized and the normally open contact of the contactor KM1 is closed.

[0016] On the basis of the above technical solution, preferably, the non-contact temperature measurement component further includes a second control circuit, and the second control circuit further includes a reset switch SB2 and a contactor KM2;

[0017] Among them, the live wire L is connected to one end of the reset switch SB2, the other end of the reset switch SB2 is connected to the coil of the contactor KM2, the coil of the contactor KM2 is connected to the neutral wire N, so that the first control circuit and the second control circuit are connected in parallel, and the normally closed contact of the contactor KM2 is provided between the alarm switch SB1 and the coil of the contactor KM1.

[0022] Compared with the prior art, the utility model of a wire drawing machine annealing wheel carbon brush holder protection device has the following advantages:

[0023] Beneficial effects:

[0024] (1) By setting a non-contact temperature measurement component and an alarm, the non-contact temperature measurement component is set on the side of the carbon brush holder. The non-contact temperature measurement component can monitor the temperature of the carbon brush holder in real time. When the carbon brush on the carbon brush holder and the annealing wheel are completely worn out by friction, the carbon brush holder will directly rub against the annealing wheel, causing the temperature of the carbon brush holder to rise. If the non-contact temperature measurement component detects that the temperature of the carbon brush holder is greater than the calibration temperature, the alarm will issue a warning, prompting the need to stop the machine to check the carbon brush holder, thereby avoiding excessive temperature of the carbon brush holder and reducing the risk of fire.

[0025] (2) Contactor KM1 and contactor KM2 are set. When the non-contact temperature measurement component detects that the temperature of the carbon brush holder is greater than the calibration temperature, the coil of contactor KM1 is energized, so that the normally open contact of contactor KM1 is closed, thereby controlling the alarm to sound an alarm. When the reset switch SB2 is pressed, the coil of contactor KM2 is energized, and the normally closed switch of contactor KM2 is disconnected, so that the coil of contactor KM1 is de-energized, thereby achieving reset. This can facilitate the control of the alarm to sound a warning and realize the reset function. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Specifically, the non-contact temperature measurement component 3 may include a first control circuit, and the first control circuit may be used to control the alarm 4 to be turned on or off.

[0047] Among them, combined Figure 2 The first control circuit includes an alarm switch SB1 and a contactor KM1. The live wire L can be connected to one end of the alarm switch SB1, and the other end of the alarm switch SB1 is connected to the coil of the contactor KM1. The coil of the contactor KM1 is connected to the neutral wire N, so that the alarm switch SB1 and the coil of the contactor KM1 are connected in series, and the normally open contact of the contactor KM1 can be connected in parallel with the alarm switch SB1, and the on and off of the first control circuit can be controlled by the contactor KM1.

[0048] like Figure 2 As shown, in some embodiments, when the non-contact temperature measurement component 3 detects that the temperature of the carbon brush holder 1 is greater than the calibrated temperature, the alarm switch SB1 is connected, so that the coil of the contactor KM1 is energized and the normally open contact of the contactor KM1 is closed.

[0049] Specifically, the non-contact temperature sensor 31 can be electrically connected to the alarm switch SB1.

The normally closed contact of the contactor KM2 can be provided between the alarm switch SB1 and the coil of the contactor KM1, so that the normally closed contact of the contactor KM2 can be disconnected by pressing the reset switch SB2, thereby controlling the first control circuit to be disconnected.

[0054] like Figure 2 As shown, in some embodiments, when the reset switch SB2 is pressed, the coil of the contactor KM2 is energized, and the normally closed contact of the contactor KM2 is disconnected, so that the coil of the contactor KM1 is de-energized.

[0055] Specifically, when the alarm 4 issues a warning and the operator discovers it, the operator will inspect the carbon brush holder 1. After the inspection is completed, the equipment can operate normally and the alarm 4 needs to be turned off. At this time, the reset switch SB2 can be pressed to energize the coil of the contactor KM2, thereby disconnecting the normally closed contacts of the contactor KM2.

[0058] And the normally open contact of the contactor KM2 is connected in parallel with the reset switch SB2, so when the coil of the contactor KM2 is energized, the normally open contact of the contactor KM2 is closed, so that the second control circuit can always remain energized.
