Description

Technical Field

[0001] This utility model relates to the field of fabric rolling mechanisms, and in particular to an abnormal output circuit for a fabric rolling mechanism and a fabric rolling mechanism for a large circular knitting machine. Background Technology

[0002] Currently, the power supply and alarm output of large circular knitting machines with servo fabric winding functions on the market are achieved by installing a rotating slip ring on a disc at the bottom of the fabric winding machine to supply power to the servo and circuitry inside the machine. When the fabric winding machine malfunctions and alarms, the controller engages or disengages a relay coil to activate the alarm stop signal. This alarm stop signal is output to the controller of the large circular knitting machine via the slip ring on the disc at the bottom of the machine. Upon receiving the alarm signal from the servo fabric winding machine, the controller immediately issues an alarm stop signal, and the large circular knitting machine stops operating.

[0003] The current control principle generally involves connecting the alarm stop signal to the normally closed contact of a relay. When there is no fault, the relay coil is energized and engaged, and the alarm signal is connected to the normally closed contact, thus blocking the alarm stop signal. When the controller detects a fault signal, the relay coil is de-energized and released, allowing the relay to conduct the fault alarm signal. This fault alarm signal is then output to the large circular knitting machine controller via a rotating slip ring, thereby achieving fault alarm stop of the large circular knitting machine.

[0004] The prerequisite for achieving fault alarm shutdown using current technology is ensuring a clear path for transmitting the alarm shutdown signal. This requires that all components in the alarm circuit path, such as relays, wires, rotary slip rings, and connectors, be functioning correctly. If any component in the alarm circuit path malfunctions, it will block the alarm output path of the fabric rolling machine. Even if the fabric rolling machine triggers a fault alarm, the large circular knitting machine controller will not receive the alarm signal, and the machine will continue to operate normally. However, in practice, issues such as damaged rotary slip rings, relay failures, loose terminals, and disconnections frequently occur. These situations prevent the alarm shutdown signal from being transmitted to the large circular knitting machine controller, allowing the machine to continue operating normally and potentially causing equipment damage. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an abnormal output circuit for a fabric winding mechanism, which can reliably and effectively output abnormal signals of the fabric winding mechanism or trigger abnormal processing, effectively avoiding the situation where abnormal output failure or failure to trigger abnormal processing is caused by the rotation conduction unit; this utility model also provides a fabric winding mechanism for a large circular knitting machine.

[0006] To achieve the above objectives, the present invention employs the following technical solution: An abnormal output circuit for a fabric winding mechanism, comprising a rotation conduction unit and an abnormal output unit, wherein: The rotating conducting unit includes a rotating part and at least one set of conducting end groups. Each set of conducting end groups includes a first conducting end and a second conducting end. When the rotating part rotates, the first conducting end and the second conducting end in the same set are connected. The abnormal output unit has an abnormal trigger state, and when the abnormal output unit is in the abnormal trigger state, it emits an abnormal signal or triggers abnormal processing. The abnormal output unit has a power supply terminal and at least one of the power supply terminals is connected to a corresponding power supply terminal on the power supply unit of the fabric rolling mechanism through a set of the conducting terminal groups. The abnormal output unit is configured to be in an abnormal trigger state when it loses power. And / or the abnormal output unit has an abnormal control terminal and the abnormal control terminal is connected to the abnormal output terminal of the control unit of the fabric rolling mechanism through a set of the conducting terminals, and the abnormal output unit is configured to be in an abnormal trigger state when its abnormal control terminal is in a high resistance state.

[0007] Since the fabric rolling mechanism is a rotary motion mechanism, the rotary conduction unit is required to achieve electrical connection when the above technical solution is adopted. Under normal conditions, the power supply unit is connected to the external power supply unit through the conductive terminal group, and the power supply unit works to supply power to the electronic and electrical equipment in the fabric rolling mechanism; The abnormal output unit has a power supply terminal, and at least one of the power supply terminals is connected to a corresponding power supply terminal on the power supply unit of the fabric winding mechanism through a set of conductive terminals. When the abnormal output unit is configured to be in an abnormal trigger state when it loses power, if the power supply unit fails to work normally, the power supply unit cannot supply power to the abnormal output unit, that is, the abnormal output unit loses power, so the abnormal output unit is in an abnormal trigger state. The abnormal output unit sends an abnormal signal or triggers abnormal processing, and the fabric winding mechanism or even the large circular knitting machine performs abnormal processing, such as stopping the machine. If the connection between the power supply terminal of the abnormal output unit and the power supply terminal of the power supply unit becomes unstable or even disconnected due to long-term operation of the rotary conductive unit, the abnormal output unit will also lose power and be in an abnormal trigger state to remind the user or stop the machine, so as to avoid subsequent failure to detect properly and cause greater accidents. The abnormal output unit has an abnormal control terminal, and the abnormal control terminal is connected to the abnormal output terminal of the control unit of the fabric winding mechanism through a set of conductive terminals. When the abnormal output unit is configured to be in an abnormal trigger state when its abnormal control terminal is in a high-resistance state, if the connection between the abnormal output terminal of the control unit and the abnormal control terminal is unstable or even disconnected, the abnormal control terminal of the abnormal output unit will be in a high-resistance state. Therefore, the abnormal output unit is in an abnormal trigger state, and the abnormal output unit sends an abnormal signal or triggers abnormal processing. The fabric winding mechanism or even the large circular knitting machine performs abnormal processing, such as stopping the machine, to remind the user or stop the machine to avoid subsequent failure to detect properly and cause a larger accident. Of course, when the abnormal output unit has an abnormal control terminal and the abnormal control terminal is connected to the abnormal output terminal of the control unit of the fabric rolling mechanism through a set of the conducting terminal groups, when the input terminal of the control unit receives an abnormal signal of the fabric rolling mechanism, the abnormal output terminal of the control unit outputs a high impedance state, thereby making the abnormal output unit in an abnormal trigger state, and the abnormal output unit sends an abnormal signal or triggers abnormal processing. The above technical solution can reliably and stably detect whether the power failure of the fabric rolling mechanism and / or whether the abnormal output line is normal.

[0008] Furthermore, the abnormal output unit includes an abnormal output switch, and the abnormal output unit controls whether to issue an abnormal signal or trigger abnormal processing by controlling the on / off state of the abnormal output switch.

[0009] By adopting the above technical solution, the abnormal output unit becomes more reasonable. The abnormal output unit controls the on / off state of the abnormal output switch according to its own state, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing.

[0010] Furthermore, the exception handling triggering circuit includes a first signal output terminal and an exception handling signal input terminal, and the exception output switch is connected in series between the first signal output terminal and the exception handling signal input terminal; If the abnormal processing signal input terminal receives a signal output from the first signal output terminal and triggers abnormal processing, and the abnormal processing signal input terminal does not receive a signal output from the first signal output terminal and does not trigger abnormal processing, then the abnormal output unit is configured such that when it is in the abnormal trigger state, the abnormal output switch is in the on state, and when it is in the non-abnormal trigger state, the abnormal output switch is in the off state. If the abnormal processing signal input terminal does not trigger abnormal processing when it receives the signal output from the first signal output terminal, and triggers abnormal processing when the abnormal processing signal input terminal does not receive the signal output from the first signal output terminal, then the abnormal output unit is configured such that when it is in the abnormal trigger state, the abnormal output switch is in the off state, and when it is in the non-abnormal trigger state, the abnormal output switch is in the on state.

[0011] By adopting the above technical solution, the abnormal output circuit of the fabric rolling mechanism becomes more reasonable; Preferably, the abnormality processing is triggered when the abnormality processing signal input terminal receives the signal output from the first signal output terminal, and the abnormality processing is not triggered when the abnormality processing signal input terminal does not receive the signal output from the first signal output terminal. Therefore, the abnormality output unit is configured such that when it is in the abnormality triggering state, the abnormality output switch is in the on state, and when it is in the non-abnormality triggering state, the abnormality output switch is in the off state.

[0012] Furthermore, the abnormal output unit has a power supply terminal, which is connected to the first conducting terminal in the conducting terminal group, and the power supply terminal in the power supply unit corresponding to the power supply terminal is connected to the second conducting terminal in the same conducting terminal group.

[0013] By adopting the above technical solution, the connection between the abnormal output unit and the power supply unit through the conduction terminal group is more reasonable.

[0014] Furthermore, the abnormal output unit has an abnormal control terminal, the abnormal control terminal of the abnormal output unit is connected to the first conducting terminal in the conducting terminal group, and the abnormal output terminal of the control unit is connected to the second conducting terminal in the same conducting terminal group; specifically, the conducting terminal group used to connect the abnormal control terminal of the abnormal output unit and the abnormal output terminal of the control unit is referred to as the fifth conducting terminal group.

[0015] By adopting the above technical solution, it is more reasonable to connect the abnormal control terminal of the abnormal output unit to the abnormal output terminal of the control unit through the conductive terminal group.

[0016] Furthermore, when the input terminal of the control unit does not receive an abnormal operation signal of the fabric winding mechanism, the abnormal output terminal of the control unit controls the abnormal output unit to be in a non-abnormal trigger state; when the input terminal of the control unit receives an abnormal operation signal of the fabric winding mechanism, the abnormal output terminal of the control unit controls the abnormal output unit to be in an abnormal trigger state.

[0017] By adopting the above technical solution, the abnormal output unit and the control unit become more reasonable; The connection in this article can be understood as a direct connection or an indirect connection; therefore, the abnormal output terminal of the control unit is directly connected to the second conducting terminal in the conducting terminal group, or the abnormal output terminal of the control unit is indirectly connected to the second conducting terminal in the conducting terminal group through other components, such as through a transition relay. When the abnormal output terminal of the control unit is directly connected to the second conducting terminal in the conducting terminal group, the abnormal output terminal of the control unit directly controls the abnormal output unit to be in a non-abnormal triggering state or an abnormal triggering state; when the abnormal output terminal of the control unit is indirectly connected to the second conducting terminal in the conducting terminal group through a transition relay, the abnormal output terminal of the control unit indirectly controls the abnormal output unit to be in a non-abnormal triggering state or an abnormal triggering state by controlling the state of the transition relay.

[0018] Furthermore, the abnormal output unit is configured to be in a non-abnormal trigger state when its abnormal control terminal is in a non-high impedance state; When the input terminal of the control unit does not receive an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit controls the abnormal control terminal of the abnormal output unit to be in a non-high impedance state; when the input terminal of the control unit receives an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit controls the abnormal control terminal of the abnormal output unit to be in a high impedance state.

[0019] By adopting the above technical solution, the abnormal output unit and the control unit are made more reasonable.

[0020] Preferably, the abnormal output terminal of the control unit is directly connected to the second conducting terminal in the conducting terminal group, and the control unit is configured as follows: When the input terminal of the control unit does not receive an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit outputs a non-high impedance state; when the input terminal of the control unit receives an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit outputs a high impedance state.

[0021] Using the above technical solution, when the input terminal of the control unit does not receive an abnormal signal from the fabric rolling mechanism, the abnormal output terminal of the control unit outputs a non-high impedance state, that is, outputs a high level or a low level. Therefore, the abnormal control terminal of the abnormal output unit is in a non-high impedance state, and the abnormal output unit is in a non-abnormal triggering state. When the input terminal of the control unit receives an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit outputs a high-impedance state. Therefore, the abnormal control terminal of the abnormal output unit is in a high-impedance state, and the abnormal output unit is in an abnormal trigger state.

[0022] Furthermore, the control unit is capable of controlling the connection and disconnection between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group; When the control unit does not receive an abnormal operation signal from the fabric winding mechanism at its input terminal, the control unit controls the power supply terminal of the power supply unit to connect with the second conductive terminal in the corresponding conductive terminal group; when the control unit receives an abnormal operation signal from the fabric winding mechanism at its input terminal, the control unit controls the power supply terminal of the power supply unit to disconnect from the second conductive terminal in the corresponding conductive terminal group.

[0023] Using the above technical solution, when the input terminal of the control unit does not receive an abnormal operation signal of the fabric rolling mechanism, the control unit controls the power supply terminal of the power supply unit to connect with the second conductive terminal in the corresponding conductive terminal group, at which time the power supply unit can supply power to the abnormal output unit; When the input terminal of the control unit receives an abnormal operation signal of the fabric rolling mechanism, the control unit controls the power supply terminal of the power supply unit to disconnect from the second conductive terminal in the corresponding conductive terminal group. At this time, the power supply unit cannot supply power to the abnormal output unit, the abnormal output unit loses power, and the abnormal output unit sends an abnormal signal or triggers abnormal processing. The above technical solution enables most or all abnormalities of the fabric rolling mechanism to output abnormal signals or trigger abnormal processing through the abnormal output unit, making management more unified and simplifying the structure of the abnormal output circuit of the fabric rolling mechanism. This makes the abnormal output circuit of the fabric rolling mechanism more reasonable, stable and reliable in operation, ensuring that abnormalities can be output reliably and avoiding poor contact that could obstruct the output of abnormal signals.

[0024] Furthermore, the abnormal output circuit of the fabric rolling mechanism includes an intermediate relay, which includes an intermediate relay coil and an intermediate relay switch. The control unit is connected to the intermediate relay coil to control its power supply and de-energization. The intermediate relay switch is connected in series between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group to control the on / off state between the two. If the intermediate relay coil is energized, the power supply terminal of the power supply unit is connected to the second conducting terminal in the corresponding conducting terminal group; if the intermediate relay coil is de-energized, the connection between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group is disconnected. Then the intermediate relay switch is a normally open switch. If the intermediate relay coil is de-energized, the power supply terminal of the power supply unit is connected to the second conducting terminal in the corresponding conducting terminal group; if the intermediate relay coil is energized, the connection between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group is disconnected. In this case, the intermediate relay switch is a normally closed switch.

[0025] By adopting the above technical solution, the control unit controls the connection and disconnection between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group through the intermediate relay, making the control unit's control over the connection and disconnection between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group more reasonable, stable and reliable.

[0026] Furthermore, the power supply terminal of the abnormal output unit includes a positive power supply terminal and a negative power supply terminal. Correspondingly, the power supply terminal of the power supply unit includes a positive power supply terminal and a negative power supply terminal. The positive power supply terminal is connected to the positive power supply terminal through a set of the conducting terminal group, and the negative power supply terminal is connected to the negative power supply terminal through a set of the conducting terminal group. Specifically, the group of conducting terminals used to connect the positive power supply terminal and the positive power supply terminal is referred to as the first conducting terminal group, and the group of conducting terminals used to connect the negative power supply terminal and the negative power supply terminal is referred to as the second conducting terminal group; the positive power supply terminal is connected to the first conducting terminal in the first conducting terminal group, the positive power supply terminal is connected to the second conducting terminal in the first conducting terminal group, the negative power supply terminal is connected to the first conducting terminal in the second conducting terminal group, and the negative power supply terminal is connected to the second conducting terminal in the second conducting terminal group.

[0027] By adopting the above technical solution, the connection between each power supply terminal of the abnormal output unit and the corresponding power supply terminal of the power supply unit through the conducting terminal group is more reasonable.

[0028] Furthermore, the control unit is connected to the power supply unit to obtain power.

[0029] By adopting the above technical solution, the configuration of the control unit is made more reasonable so that it can work normally; specifically, the positive terminal of the control unit is connected to the positive power supply terminal of the power supply unit, and the negative terminal of the control unit is connected to the negative power supply terminal of the power supply unit.

[0030] Furthermore, the control unit controls the connection and disconnection between the positive power supply terminal of the power supply unit and the second conducting terminal of the first conducting terminal group, and / or controls the connection and disconnection between the negative power supply terminal of the power supply unit and the second conducting terminal of the second conducting terminal group.

[0031] If one or both of the connections between the positive power supply terminal of the power supply unit and the second conducting terminal of the first conducting terminal group, and between the negative power supply terminal of the power supply unit and the second conducting terminal of the second conducting terminal group are disconnected, the abnormal output unit will be unable to form a circuit with the power supply unit, that is, the abnormal output unit will be in a power-off state. Preferably, the control unit controls the connection between the positive power supply terminal of the power supply unit and the second conductive terminal of the first conductive terminal group, and controls the connection between the negative power supply terminal of the power supply unit and the second conductive terminal of the second conductive terminal group; when the control unit controls the disconnection between the power supply terminal of the power supply unit and the conductive terminal group, the control unit simultaneously disconnects the connection between the positive power supply terminal of the power supply unit and the second conductive terminal of the first conductive terminal group, and disconnects the connection between the negative power supply terminal of the power supply unit and the second conductive terminal of the second conductive terminal group, so that the control unit can more reliably disconnect the connection between the power supply unit and the abnormal output unit.

[0032] Furthermore, when the control unit is able to control the connection and disconnection between the positive power supply terminal of the power supply unit and the second conducting terminal of the first conducting terminal group, the intermediate relay switch is connected in series between the positive power supply terminal of the power supply unit and the second conducting terminal of the first conducting terminal group. When the control unit is able to control the connection and disconnection between the negative power supply terminal of the power supply unit and the second conducting terminal of the second conducting terminal group, the intermediate relay switch is connected in series between the negative power supply terminal of the power supply unit and the second conducting terminal of the second conducting terminal group.

[0033] By adopting the above technical solution, the setting of the intermediate relay switch is made more reasonable; Preferably, the intermediate relay has at least two intermediate relay switches, which are respectively connected in series between the positive power supply terminal of the power supply unit and the second conducting terminal of the first conducting terminal group, and between the negative power supply terminal of the power supply unit and the second conducting terminal of the second conducting terminal group. The above technical solution makes the abnormal output circuit of the fabric rolling mechanism more reliable. When one of the intermediate relay switches fails and cannot cut off the corresponding line, while the other intermediate relay switch works normally and cuts off the corresponding line, the intermediate relay can still cut off the power supply connection between the power supply unit and the abnormal output unit.

[0034] Furthermore, one end of the intermediate relay coil is connected to the abnormal output terminal of the control unit, and the other end is connected to the positive or negative power supply terminal of the power supply unit.

[0035] By adopting the above technical solution, the arrangement of the intermediate relay coil is made more reasonable; When the intermediate relay coil is connected to the positive power supply terminal of the power supply unit, the intermediate relay coil is energized when the abnormal output terminal of the control unit outputs a low level, and the intermediate relay coil is de-energized when the abnormal output terminal of the control unit has no output, i.e., it is in a high impedance state. When the intermediate relay coil is connected to the negative power supply terminal of the power supply unit, the intermediate relay coil is energized when the abnormal output terminal of the control unit outputs a high level, and the intermediate relay coil is de-energized when the abnormal output terminal of the control unit has no output, i.e., it is in a high impedance state. Specifically, the control unit is configured such that: when the input terminal of the control unit does not receive an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit outputs a non-high impedance state; when the input terminal of the control unit receives an abnormal signal from the fabric winding mechanism, the abnormal output terminal of the control unit outputs a high impedance state. The intermediate relay is configured such that when the intermediate relay coil is energized, it connects the power supply terminal of the power supply unit to the second conducting terminal in the corresponding conducting terminal group; and when the intermediate relay coil is de-energized, it disconnects the connection between the power supply terminal of the power supply unit and the second conducting terminal in the corresponding conducting terminal group. Therefore, the intermediate relay switch is a normally open switch.

[0036] Furthermore, the abnormal output unit adopts a relay, which includes a first relay coil and a first relay switch. The first relay switch is formed as the abnormal output switch, and the first power supply terminal and the second power supply terminal of the first relay coil are formed as the power supply terminal of the abnormal output unit. If the abnormality handling signal input terminal receives the signal output from the first signal output terminal, the abnormality handling is triggered; if the abnormality handling signal input terminal does not receive the signal output from the first signal output terminal, the first relay switch is a normally closed switch. If the abnormality handling signal input terminal receives the signal output from the first signal output terminal but does not trigger abnormality handling, and the abnormality handling signal input terminal does not receive the signal output from the first signal output terminal but triggers abnormality handling, then the first relay switch is a normally open switch.

[0037] In this article, a switch on a relay can be understood as: a common terminal on the relay, a normally open or normally closed contact, and related mechanical parts; a normally open switch on a relay can be understood as: a common terminal on the relay, a normally open contact, and related mechanical parts; a normally closed switch on a relay can be understood as: a common terminal on the relay, a normally closed contact, and related mechanical parts. This explanation is for ease of understanding and is not intended to be restrictive. By adopting the above technical solution, the abnormal output unit is made more reasonable. The abnormal output unit adopts a relay. The first relay coil can switch the on and off state of the first relay switch by gaining and losing power, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing.

[0038] Furthermore, the abnormal output unit adopts a relay module, which has a third power supply terminal, a fourth power supply terminal, a control signal input terminal, and a second relay switch. The third power supply terminal and the fourth power supply terminal form the power supply terminal of the abnormal output unit, the control signal input terminal forms the abnormal control terminal of the abnormal output unit, and the second relay switch forms the abnormal output switch. If the abnormality handling signal input terminal receives the signal output from the first signal output terminal, the abnormality handling is triggered; if the abnormality handling signal input terminal does not receive the signal output from the first signal output terminal, the second relay switch is a normally closed switch. If the abnormality handling signal input terminal receives the signal output from the first signal output terminal but does not trigger abnormality handling, and the abnormality handling signal input terminal does not receive the signal output from the first signal output terminal but triggers abnormality handling, then the second relay switch is a normally open switch.

[0039] In this article, a switch on a relay module can be understood as: a common terminal on the relay module, a normally open or normally closed contact, and related mechanical parts; a normally open switch on a relay module can be understood as: a common terminal on the relay module, a normally open contact, and related mechanical parts; a normally closed switch on a relay module can be understood as: a common terminal on the relay module, a normally closed contact, and related mechanical parts. This explanation is for ease of understanding and is not intended to be restrictive. By adopting the above technical solution, the abnormal output unit is made more reasonable. The abnormal output unit adopts a relay module. The abnormal output unit can switch the on / off state of the second relay switch by gaining or losing power, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing. In addition, the abnormal output unit can also switch the on / off state of the second relay switch by the signal change at the control signal input terminal, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing.

[0040] Furthermore, the power input terminal of the power supply unit is connected to the power output terminal of the external power output unit through the conducting terminal group to obtain power.

[0041] By adopting the above technical solution, the abnormal output circuit of the fabric rolling mechanism becomes more reasonable.

[0042] Furthermore, the power supply unit adopts a switching power supply.

[0043] By adopting the above technical solution, the power supply unit becomes more reasonable, and can convert the voltage and current input from the external power output unit into the working voltage and current of the electronic and electrical equipment in the fabric rolling mechanism, ensuring that the electronic and electrical equipment in the fabric rolling mechanism can work normally.

[0044] Furthermore, the power input terminal of the power supply unit includes a first power input terminal and a second power input terminal, and correspondingly, the power output terminal of the external power output unit includes a first power output terminal and a second power output terminal; the first power input terminal of the power supply unit is connected to the first power output terminal of the external power output unit through a set of the conducting terminal group, and the second power input terminal of the power supply unit is connected to the second power output terminal of the external power output unit through a set of the conducting terminal group; Specifically, the group of conducting terminals used to connect the first power input terminal of the power supply unit to the first power output terminal of the external power output unit is referred to as the third group of conducting terminals, and the group of conducting terminals used to connect the second power input terminal of the power supply unit to the second power output terminal of the external power output unit is referred to as the fourth group of conducting terminals; the first power input terminal of the power supply unit is connected to the second conducting terminal in the third group of conducting terminals, the first power output terminal of the external power output unit is connected to the first conducting terminal in the third group of conducting terminals, the second power input terminal of the power supply unit is connected to the second conducting terminal in the fourth group of conducting terminals, and the second power output terminal of the external power output unit is connected to the first conducting terminal in the fourth group of conducting terminals.

[0045] By adopting the above technical solution, the connection between the power supply unit and the external power output unit through the rotating conduction unit is made more reasonable.

[0046] Furthermore, the rotary conduction unit adopts a rotary slip ring, i.e., an electric slip ring; the control unit adopts a PLC or a microcontroller.

[0047] By adopting the above technical solution, the rotary conduction unit and the control unit are made more reasonable.

[0048] Furthermore, the fabric rolling mechanism is applied to a large circular knitting machine, and the external power output unit uses the power supply on the large circular knitting machine.

[0049] The above technical solution makes the circuit more reasonable. Specifically, the external power output unit uses the 220V power supply from the large circular knitting machine.

[0050] Furthermore, the abnormality handling is a shutdown operation, the first signal output terminal is the alarm signal output terminal on the large circular knitting machine, and the abnormality handling signal input terminal is the alarm shutdown input terminal on the large circular knitting machine controller; specifically, the alarm signal output terminal on the large circular knitting machine is the 0V or 24V power supply on the large circular knitting machine.

[0051] By adopting the above technical solution, the abnormal handling operation is made more reasonable, and the shutdown can avoid equipment damage, thereby reducing losses. Since the fabric winding mechanism is used in the circular knitting machine, the fabric winding mechanism will cooperate with other mechanisms of the circular knitting machine. The first signal output terminal is the alarm signal output terminal on the circular knitting machine controller, and the abnormal handling signal input terminal is the alarm shutdown input terminal on the circular knitting machine controller. This makes the settings of the first signal output terminal and the abnormal handling signal input terminal more reasonable. When the abnormal output circuit of the fabric winding mechanism detects an abnormality, it triggers the abnormal triggering circuit on the circular knitting machine, and the controller of the circular knitting machine performs overall abnormal handling.

[0052] A large circular knitting machine fabric winding mechanism includes the aforementioned fabric winding mechanism abnormal output circuit.

[0053] By adopting the above technical solution, the fabric winding mechanism of the large circular knitting machine is made more reasonable, enabling the large circular knitting machine to reliably and stably detect its power failure, and effectively avoiding abnormal output failure caused by the rotating conduction unit.

[0054] Compared with the prior art, the present invention has the following beneficial effects: (1) The abnormal output circuit of the fabric rolling mechanism and the fabric rolling mechanism of the large circular knitting machine of this utility model can reliably and effectively output abnormal signals of the fabric rolling mechanism or trigger abnormal processing, effectively avoiding the situation of abnormal output failure or failure to trigger abnormal processing due to the rotation conduction unit.

[0055] (2) The abnormal output circuit of the fabric rolling mechanism and the fabric rolling mechanism of the large circular knitting machine of this utility model are reasonably designed, reliable and stable in operation. Attached Figure Description

[0064] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0065] See Figures 1 to 2 This utility model provides an abnormal output circuit for a fabric rolling mechanism, which is used in a fabric rolling mechanism and includes a rotation conduction unit 1 and an abnormal output unit 2, wherein: The rotating conducting unit 1 includes a rotating part and at least one set of conducting end groups 101. Each set of conducting end groups 101 includes a first conducting end 1011 and a second conducting end 1012. When the rotating part rotates, the first conducting end 1011 and the second conducting end 1012 in the same set are connected. The abnormal output unit 2 has an abnormal trigger state, and when the abnormal output unit 2 is in the abnormal trigger state, it sends an abnormal signal or triggers abnormal processing. The abnormal output unit 2 has a power supply terminal 201 and at least one of the power supply terminals 201 is connected to the corresponding power supply terminal 301 on the power supply unit 3 of the fabric rolling mechanism through a set of the conducting terminal group 101. The abnormal output unit 2 is configured to be in an abnormal trigger state when it loses power. And / or the abnormal output unit 2 has an abnormal control terminal 202 and the abnormal control terminal 202 is connected to the abnormal output terminal 401 of the control unit 4 of the fabric rolling mechanism through a set of the conducting terminal group 101. The abnormal output unit 2 is configured to be in an abnormal trigger state when its abnormal control terminal 202 is in a high resistance state.

[0066] Since the fabric rolling mechanism is a rotary motion mechanism, the rotary conduction unit 1 is required to achieve electrical connection when the above technical solution is adopted. Under normal conditions, the power supply unit 3 is connected to the external power supply unit through the conductive terminal group 101, and the power supply unit 3 works to supply power to the electronic and electrical equipment in the fabric rolling mechanism; The abnormal output unit 2 has a power supply terminal 201, and at least one of the power supply terminals 201 is connected to the corresponding power supply terminal 301 on the power supply unit 3 of the fabric rolling mechanism through a set of conductive terminal groups 101. When the abnormal output unit 2 is configured to be in an abnormal trigger state when it loses power, if the power supply unit 3 fails to work normally, the power supply unit 3 cannot supply power to the abnormal output unit 2, that is, the abnormal output unit 2 loses power, so the abnormal output unit 2 is in an abnormal trigger state. The abnormal output unit 2 sends an abnormal signal or triggers abnormal processing, and the fabric rolling mechanism or even the large circular knitting machine performs abnormal processing, such as stopping the machine. If the rotation conductive unit 1 causes the connection between the power supply terminal 201 of the abnormal output unit 2 and the power supply terminal 301 of the power supply unit 3 to be unstable or even disconnected due to long-term operation, the abnormal output unit 2 will also lose power and be in an abnormal trigger state to remind the user or stop the machine, so as to avoid subsequent failure to detect properly and cause greater accidents. The abnormal output unit 2 has an abnormal control terminal 202, and the abnormal control terminal 202 is connected to the abnormal output terminal 401 of the control unit 4 of the fabric winding mechanism through a set of the conducting terminal group 101. When the abnormal output unit 2 is configured to be in an abnormal trigger state when its abnormal control terminal 202 is in a high resistance state, if the connection between the abnormal output terminal 401 of the control unit 4 and the abnormal control terminal 202 is unstable or even disconnected, the abnormal control terminal 202 of the abnormal output unit 2 will be in a high resistance state. Therefore, the abnormal output unit 2 is in an abnormal trigger state. The abnormal output unit 2 sends an abnormal signal or triggers abnormal processing. The fabric winding mechanism or even the large circular knitting machine performs abnormal processing, such as stopping the machine, to remind the user or stop the machine to avoid subsequent failure to detect normally and cause a larger accident. Of course, when the abnormal output unit 2 has an abnormal control terminal 202 and the abnormal control terminal 202 is connected to the abnormal output terminal 401 of the control unit 4 of the fabric rolling mechanism through a set of the conducting terminal group 101, when the input terminal of the control unit 4 receives an abnormal signal of the fabric rolling mechanism, the abnormal output terminal 401 of the control unit 4 outputs a high impedance state, thereby making the abnormal output unit 2 in an abnormal trigger state, and the abnormal output unit 2 sends an abnormal signal or triggers abnormal processing. The above technical solution can reliably and stably detect whether the power failure of the fabric rolling mechanism and / or the abnormal output line is normal.

[0067] Furthermore, the abnormal output unit 2 includes an abnormal output switch 203, and the abnormal output unit 2 controls whether to issue an abnormal signal or trigger abnormal processing by controlling the on / off state of the abnormal output switch 203.

[0068] By adopting the above technical solution, the abnormal output unit 2 becomes more reasonable. The abnormal output unit 2 controls the on / off state of the abnormal output switch 203 according to its own state, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing.

[0069] Furthermore, the abnormal handling triggering line 5 includes a first signal output terminal 501 and an abnormal handling signal input terminal 502, and the abnormal output switch 203 is connected in series between the first signal output terminal 501 and the abnormal handling signal input terminal 502. If the abnormal processing signal input terminal 502 receives a signal output from the first signal output terminal 501 and triggers abnormal processing, and the abnormal processing signal input terminal 502 does not receive a signal output from the first signal output terminal 501 and does not trigger abnormal processing, then the abnormal output unit 2 is configured such that when it is in the abnormal trigger state, the abnormal output switch 203 is in the on state, and when it is in the non-abnormal trigger state, the abnormal output switch 203 is in the off state. If the abnormal processing signal input terminal 502 does not trigger abnormal processing when it receives the signal output by the first signal output terminal 501, and triggers abnormal processing when the abnormal processing signal input terminal 502 does not receive the signal output by the first signal output terminal 501, then the abnormal output unit 2 is configured such that when it is in the abnormal trigger state, the abnormal output switch 203 is in the off state, and when it is in the non-abnormal trigger state, the abnormal output switch 203 is in the on state.

[0070] By adopting the above technical solution, the abnormal output circuit of the fabric rolling mechanism becomes more reasonable; Preferably, the abnormal processing signal input terminal 502 triggers abnormal processing when it receives a signal output from the first signal output terminal 501, and does not trigger abnormal processing when it does not receive a signal output from the first signal output terminal 501. Therefore, the abnormal output unit 2 is configured such that when it is in an abnormal trigger state, the abnormal output switch 203 is in a conducting state, and when it is in a non-abnormal trigger state, the abnormal output switch 203 is in a disconnected state.

[0071] Furthermore, the abnormal output unit 2 has a power supply terminal 201, which is connected to the first conducting terminal 1011 in the conducting terminal group 101, and the power supply terminal 301 in the power supply unit 3 corresponding to the power supply terminal 201 is connected to the second conducting terminal 1012 in the same conducting terminal group 101.

[0072] By adopting the above technical solution, it is more reasonable to connect the abnormal output unit 2 to the power supply unit 3 through the conduction terminal group 101.

[0073] Furthermore, the abnormal output unit 2 has an abnormal control terminal 202, which is connected to the first conducting terminal 1011 in the conducting terminal group 101, and the abnormal output terminal 401 of the control unit 4 is connected to the second conducting terminal 1012 in the same conducting terminal group 101; specifically, the conducting terminal group 101 used to connect the abnormal control terminal 202 of the abnormal output unit 2 and the abnormal output terminal 401 of the control unit 4 is referred to as the fifth conducting terminal group 101e.

[0074] By adopting the above technical solution, it is more reasonable to connect the abnormal control terminal 202 of the abnormal output unit 2 to the abnormal output terminal 401 of the control unit 4 through the conduction terminal group 101.

[0075] Furthermore, when the input terminal of the control unit 4 does not receive an abnormal operation signal of the fabric rolling mechanism, the abnormal output terminal 401 of the control unit 4 controls the abnormal output unit 2 to be in a non-abnormal trigger state; when the input terminal of the control unit 4 receives an abnormal operation signal of the fabric rolling mechanism, the abnormal output terminal 401 of the control unit 4 controls the abnormal output unit 2 to be in an abnormal trigger state.

[0076] By adopting the above technical solution, the abnormal output unit 2 and the control unit 4 are made more reasonable; The connection in this article can be understood as a direct connection or an indirect connection; therefore, the abnormal output terminal 401 of the control unit 4 is directly connected to the second conducting terminal 1012 in the conducting terminal group 101, or the abnormal output terminal 401 of the control unit 4 is indirectly connected to the second conducting terminal 1012 in the conducting terminal group 101 through other components, such as through a transition relay. When the abnormal output terminal 401 of the control unit 4 is directly connected to the second conducting terminal 1012 in the conducting terminal group 101, the abnormal output terminal 401 of the control unit 4 directly controls the abnormal output unit 2 to be in a non-abnormal triggering state or an abnormal triggering state; when the abnormal output terminal 401 of the control unit 4 is indirectly connected to the second conducting terminal 1012 in the conducting terminal group 101 through a transition relay, the abnormal output terminal 401 of the control unit 4 indirectly controls the abnormal output unit 2 to be in a non-abnormal triggering state or an abnormal triggering state by controlling the state of the transition relay.

[0077] Furthermore, the abnormal output unit 2 is configured to be in a non-abnormal trigger state when its abnormal control terminal 202 is in a non-high impedance state; When the input terminal of the control unit 4 does not receive an abnormal signal of the fabric winding mechanism, the abnormal output terminal 401 of the control unit 4 controls the abnormal control terminal 202 of the abnormal output unit 2 to be in a non-high impedance state; when the input terminal of the control unit 4 receives an abnormal signal of the fabric winding mechanism, the abnormal output terminal 401 of the control unit 4 controls the abnormal control terminal 202 of the abnormal output unit 2 to be in a high impedance state.

[0078] By adopting the above technical solution, the abnormal output unit 2 and the control unit 4 become more reasonable.

[0079] Preferably, the abnormal output terminal of the control unit is directly connected to the second conducting terminal in the conducting terminal group, and the control unit is configured as follows: When the input terminal of the control unit 4 does not receive an abnormal signal from the fabric winding mechanism, the abnormal output terminal 401 of the control unit 4 outputs a non-high impedance state; when the input terminal of the control unit 4 receives an abnormal signal from the fabric winding mechanism, the abnormal output terminal 401 of the control unit 4 outputs a high impedance state.

[0080] Using the above technical solution, when the input terminal of the control unit 4 does not receive an abnormal signal of the fabric rolling mechanism, the abnormal output terminal 401 of the control unit 4 outputs a non-high impedance state, that is, outputs a high level or a low level. Therefore, the abnormal control terminal 202 of the abnormal output unit 2 is in a non-high impedance state, and the abnormal output unit 2 is in a non-abnormal triggering state. When the input terminal of the control unit 4 receives an abnormal signal of the fabric rolling mechanism, the abnormal output terminal 401 of the control unit 4 outputs a high impedance state. Therefore, the abnormal control terminal 202 of the abnormal output unit 2 is in a high impedance state, and the abnormal output unit 2 is in an abnormal trigger state.

[0081] Furthermore, the control unit 4 can control the connection and disconnection between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101; When the input terminal of the control unit 4 does not receive an abnormal operation signal of the fabric rolling mechanism, the control unit 4 controls the power supply terminal 301 of the power supply unit 3 to connect with the second conductive terminal 1012 in the corresponding conductive terminal group 101; when the input terminal of the control unit 4 receives an abnormal operation signal of the fabric rolling mechanism, the control unit 4 controls the power supply terminal 301 of the power supply unit 3 to disconnect from the second conductive terminal 1012 in the corresponding conductive terminal group 101.

[0082] Using the above technical solution, when the input terminal of the control unit 4 does not receive an abnormal operation signal of the fabric rolling mechanism, the control unit 4 controls the power supply terminal 301 of the power supply unit 3 to connect with the second conductive terminal 1012 in the corresponding conductive terminal group 101. At this time, the power supply unit 3 can supply power to the abnormal output unit 2. When the input terminal of the control unit 4 receives an abnormal operation signal of the fabric rolling mechanism, the control unit 4 controls the power supply terminal 301 of the power supply unit 3 to disconnect from the second conductive terminal 1012 in the corresponding conductive terminal group 101. At this time, the power supply unit 3 cannot supply power to the abnormal output unit 2, the abnormal output unit 2 loses power, and the abnormal output unit 2 sends an abnormal signal or triggers abnormal processing. The above technical solution enables most or all abnormalities of the fabric rolling mechanism to output abnormal signals or trigger abnormal processing through the abnormal output unit 2, making management more unified and simplifying the structure of the abnormal output circuit of the fabric rolling mechanism. This makes the abnormal output circuit of the fabric rolling mechanism more reasonable, stable and reliable in operation, ensuring that abnormalities can be output reliably and avoiding poor contact that could obstruct the output of abnormal signals.

[0083] Furthermore, the abnormal output circuit of the fabric rolling mechanism includes an intermediate relay 6, which includes an intermediate relay coil 601 and an intermediate relay switch 602. The control unit 4 is connected to the intermediate relay coil 601 to control its power supply and de-energization. The intermediate relay switch 602 is connected in series between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101 to control the on / off state between the two. If the intermediate relay coil 601 is energized, the power supply terminal 301 of the power supply unit 3 is connected to the second conducting terminal 1012 in the corresponding conducting terminal group 101; if the intermediate relay coil 601 is de-energized, the connection between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101 is disconnected. Then the intermediate relay switch 602 is a normally open switch. If the intermediate relay coil 601 is de-energized, the power supply terminal 301 of the power supply unit 3 is connected to the second conducting terminal 1012 in the corresponding conducting terminal group 101; if the intermediate relay coil 601 is energized, the connection between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101 is disconnected. Then the intermediate relay switch 602 is a normally closed switch.

[0084] By adopting the above technical solution, the control unit 4 controls the connection and disconnection between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101 through the intermediate relay 6, so that the control unit 4 controls the connection and disconnection between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101 in a more reasonable, stable and reliable manner.

[0085] Furthermore, the power supply terminal 201 of the abnormal output unit 2 includes a positive power supply terminal 201a and a negative power supply terminal 201b. Correspondingly, the power supply terminal 301 of the power supply unit 3 includes a positive power supply terminal 301a and a negative power supply terminal 301b. The positive power supply terminal 201a is connected to the positive power supply terminal 301a through a set of the conducting terminal group 101, and the negative power supply terminal 201b is connected to the negative power supply terminal 301b through a set of the conducting terminal group 101. Specifically, the conductive terminal group 101 used to connect the positive power supply terminal 201a and the positive power supply terminal 301a is designated as the first conductive terminal group 101a, and the conductive terminal group 101 used to connect the negative power supply terminal 201b and the negative power supply terminal 301b is designated as the second conductive terminal group 101b; the positive power supply terminal 201a is connected to the first conductive terminal 1011 in the first conductive terminal group 101a, the positive power supply terminal 301a is connected to the second conductive terminal 1012 in the first conductive terminal group 101a, the negative power supply terminal 201b is connected to the first conductive terminal 1011 in the second conductive terminal group 101b, and the negative power supply terminal 301b is connected to the second conductive terminal 1012 in the second conductive terminal group 101b.

[0086] By adopting the above technical solution, the connection between each power supply terminal 201 of the abnormal output unit 2 and the corresponding power supply terminal 301 of the power supply unit 3 through the conduction terminal group 101 is more reasonable.

[0087] Furthermore, the control unit 4 is connected to the power supply unit 3 to obtain power.

[0088] By adopting the above technical solution, the configuration of the control unit 4 is made more reasonable so that it can work normally; specifically, the positive terminal of the control unit 4 is connected to the positive power supply terminal 301a of the power supply unit 3, and the negative terminal of the control unit 4 is connected to the negative power supply terminal 301b of the power supply unit 3.

[0089] Furthermore, the control unit 4 controls the connection and disconnection between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a, and / or controls the connection and disconnection between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b.

[0090] If one or both of the connections between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a, and between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b are cut off, the abnormal output unit 2 will be unable to form a circuit with the power supply unit 3, that is, the abnormal output unit 2 will be in a power-off state. Preferably, the control unit 4 controls the connection and disconnection between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a, and controls the connection and disconnection between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b. When the control unit 4 controls the disconnection of the connection between the power supply terminal 301 of the power supply unit 3 and the conducting terminal group 101, the control unit 4 simultaneously disconnects the connection between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a, and disconnects the connection between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b, so that the control unit 4 can more reliably disconnect the connection between the power supply unit 3 and the abnormal output unit 2.

[0091] Furthermore, when the control unit 4 is able to control the connection and disconnection between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a, the intermediate relay switch 602 is connected in series between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a. When the control unit 4 can control the connection and disconnection between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b, the intermediate relay switch 602 is connected in series between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b.

[0092] By adopting the above technical solution, the setting of the intermediate relay switch 602 is made more reasonable; Preferably, the intermediate relay 6 has at least two intermediate relay switches 602, which are respectively connected in series between the positive power supply terminal 301a of the power supply unit 3 and the second conducting terminal 1012 of the first conducting terminal group 101a, and between the negative power supply terminal 301b of the power supply unit 3 and the second conducting terminal 1012 of the second conducting terminal group 101b. The above technical solution makes the abnormal output circuit of the fabric rolling mechanism more reliable. When one of the intermediate relay switches 602 in the intermediate relay 6 fails and cannot cut off the corresponding line, while the other intermediate relay switch 602 works normally and cuts off the corresponding line, the intermediate relay 6 can still cut off the power supply connection between the power supply unit 3 and the abnormal output unit 2.

[0093] Furthermore, one end of the intermediate relay coil 601 is connected to the abnormal output terminal 401 of the control unit 4, and the other end is connected to the positive power supply terminal 301a or the negative power supply terminal 301b of the power supply unit 3.

[0094] By adopting the above technical solution, the arrangement of the intermediate relay coil 601 is made more reasonable; When the intermediate relay coil 601 is connected to the positive power supply terminal 301a of the power supply unit 3, the intermediate relay coil 601 is energized when the abnormal output terminal 401 of the control unit 4 outputs a low level, and the intermediate relay coil 601 is de-energized when the abnormal output terminal 401 of the control unit 4 has no output, i.e., it is in a high impedance state. When the intermediate relay coil 601 is connected to the negative power supply terminal 301b of the power supply unit 3, the intermediate relay coil 601 is energized when the abnormal output terminal 401 of the control unit 4 outputs a high level, and the intermediate relay coil 601 is de-energized when the abnormal output terminal 401 of the control unit 4 has no output, i.e., it is in a high impedance state. Specifically, the control unit 4 is configured such that: when the input terminal of the control unit 4 does not receive an abnormal signal of the fabric winding mechanism, the abnormal output terminal 401 of the control unit 4 outputs a non-high impedance state; when the input terminal of the control unit 4 receives an abnormal signal of the fabric winding mechanism, the abnormal output terminal 401 of the control unit 4 outputs a high impedance state. The intermediate relay 6 is configured such that: when the intermediate relay coil 601 is energized, it connects the power supply terminal 301 of the power supply unit 3 to the second conducting terminal 1012 in the corresponding conducting terminal group 101; when the intermediate relay coil 601 is de-energized, it disconnects the connection between the power supply terminal 301 of the power supply unit 3 and the second conducting terminal 1012 in the corresponding conducting terminal group 101. Therefore, the intermediate relay switch 602 is a normally open switch.

[0095] Further, see Figure 1 In some embodiments, the abnormal output unit 2 is a relay, which includes a first relay coil 204 and a first relay switch 205. The first relay switch 205 is formed as the abnormal output switch 203, and the first power supply terminal 2041 and the second power supply terminal 2042 of the first relay coil 204 are formed as the power supply terminal 201 of the abnormal output unit 2. If the abnormal processing signal input terminal 502 receives a signal output from the first signal output terminal 501 and triggers abnormal processing, and the abnormal processing signal input terminal 502 does not receive a signal output from the first signal output terminal 501 and does not trigger abnormal processing, then the first relay switch 205 is a normally closed switch. If the abnormality handling signal input terminal 502 does not trigger abnormality handling when it receives the signal output from the first signal output terminal 501, and triggers abnormality handling when it does not receive the signal output from the first signal output terminal 501, then the first relay switch 205 is a normally open switch.

[0096] In this article, a switch on a relay can be understood as: a common terminal on the relay, a normally open or normally closed contact, and related mechanical parts; a normally open switch on a relay can be understood as: a common terminal on the relay, a normally open contact, and related mechanical parts; a normally closed switch on a relay can be understood as: a common terminal on the relay, a normally closed contact, and related mechanical parts. This explanation is for ease of understanding and is not intended to be restrictive. By adopting the above technical solution, the abnormal output unit 2 is made more reasonable. The abnormal output unit 2 adopts a relay. The first relay coil 204 can switch the on and off state of the first relay switch 205 by gaining and losing power, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing.

[0097] Further, see Figure 2 In some embodiments, the abnormal output unit 2 is a relay module, which has a third power terminal 206, a fourth power terminal 207, a control signal input terminal 208, and a second relay switch 209. The third power terminal 206 and the fourth power terminal 207 form the power terminal 201 of the abnormal output unit 2, the control signal input terminal 208 forms the abnormal control terminal 202 of the abnormal output unit 2, and the second relay switch 209 forms the abnormal output switch 203. If the abnormal processing signal input terminal 502 receives a signal output from the first signal output terminal 501 and triggers abnormal processing, and the abnormal processing signal input terminal 502 does not receive a signal output from the first signal output terminal 501 and does not trigger abnormal processing, then the second relay switch 209 is a normally closed switch. If the abnormality handling signal input terminal 502 does not trigger abnormality handling when it receives the signal output from the first signal output terminal 501, and triggers abnormality handling when it does not receive the signal output from the first signal output terminal 501, then the second relay switch 209 is a normally open switch.

[0098] In this article, a switch on a relay module can be understood as: a common terminal on the relay module, a normally open or normally closed contact, and related mechanical parts; a normally open switch on a relay module can be understood as: a common terminal on the relay module, a normally open contact, and related mechanical parts; a normally closed switch on a relay module can be understood as: a common terminal on the relay module, a normally closed contact, and related mechanical parts. This explanation is for ease of understanding and is not intended to be restrictive. By adopting the above technical solution, the abnormal output unit 2 is made more reasonable. The abnormal output unit 2 adopts a relay module. The abnormal output unit 2 can switch the on / off state of the second relay switch 209 by gaining or losing power, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing. In addition, the abnormal output unit 2 can also switch the on / off state of the second relay switch 209 by the signal change at the control signal input terminal 208, thereby realizing whether to issue an abnormal signal or whether to trigger abnormal processing.

[0099] Furthermore, the power input terminal 302 of the power supply unit 3 is connected to the power output terminal 701 of the external power output unit 7 through the conducting terminal group 101 to obtain power.

[0100] By adopting the above technical solution, the abnormal output circuit of the fabric rolling mechanism becomes more reasonable.

[0101] Furthermore, the power supply unit 3 adopts a switching power supply.

[0102] By adopting the above technical solution, the power supply unit 3 becomes more reasonable, and can convert the voltage and current input by the external power output unit 7 into the working voltage and current of the electronic and electrical equipment in the fabric rolling mechanism, so as to ensure that the electronic and electrical equipment in the fabric rolling mechanism can work normally.

[0103] Furthermore, the power input terminal 302 of the power supply unit 3 includes a first power input terminal 302a and a second power input terminal 302b. Correspondingly, the power output terminal 701 of the external power output unit 7 includes a first power output terminal 701a and a second power output terminal 701b. The first power input terminal 302a of the power supply unit 3 is connected to the first power output terminal 701a of the external power output unit 7 through a set of the conducting terminal group 101, and the second power input terminal 302b of the power supply unit 3 is connected to the second power output terminal 701b of the external power output unit 7 through a set of the conducting terminal group 101.
