Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and in particular to a control circuit, a fabric winding machine circuit, a circular knitting machine circuit, a fabric winding machine, and a circular knitting machine. Background Technology

[0002] Currently, when debugging and repairing fabric rolling machines and circular knitting machines, or when malfunctions occur during production, the operation is handled by pressing a button panel or manually cranking the machine. However, the button panels on the equipment are fixed in one position; for example, the button panel of a circular knitting machine is mounted on one of the three feet of the large circular knitting machine. The button panel has three buttons: start, stop, and jog. There is only one manual crank, mounted on the foot of the main motor of the large circular knitting machine.

[0003] This means that when debugging and repairing the machine, workers or technicians cannot reach the buttons and need other people to help press them. Especially when two people are working together, it is difficult to control the timing and degree, which brings great inconvenience to debugging or repairing the machine. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a control circuit equipped with a wireless transmitting unit and a wireless receiving unit. Users can control the fabric rolling machine or circular knitting machine by operating the wireless transmitting unit from any location within the communication range of both units, facilitating operation, especially during machine debugging. This utility model also provides a fabric rolling machine circuit, a circular knitting machine circuit, a fabric rolling machine, and a circular knitting machine.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A control circuit for use on a fabric winding machine or circular knitting machine, comprising:

[0007] A wireless transmitting unit is provided with at least one function button, and the wireless transmitting unit sends a corresponding wireless control signal according to the operation of the function button.

[0008] The system includes a wireless receiving unit with a signal output switch matching the number of function buttons. The wireless receiving unit is wirelessly connected to the wireless transmitting unit and controls the on / off state of the corresponding signal output switch according to the received wireless control signal. The first end of the signal output switch is used to connect to a control signal source, and the second end of the signal output switch is used to connect to the function control input terminal of the corresponding function on the control unit of the fabric rolling machine or circular knitting machine.

[0009] By adopting the above technical solution, since the wireless transmitting unit and the wireless receiving unit communicate wirelessly, the user can operate the wireless transmitting unit at any position within the communication range of the two to control the fabric rolling machine or circular knitting machine, which is convenient for the user, especially when debugging the machine.

[0010] Furthermore, the wireless receiving unit transmits the corresponding signal to the control unit of the fabric rolling machine or circular knitting machine by controlling the on / off state of the signal output switch. The original operation buttons on the fabric rolling machine or circular knitting machine also transmit the corresponding signal to the control unit of the fabric rolling machine or circular knitting machine by controlling their on / off state. Therefore, the signal output switch in the wireless receiving unit only needs to be connected in parallel with the operation button of the corresponding function. The installation is simple and it is also convenient for later maintenance and replacement. Moreover, it can modify existing fabric rolling machines or circular knitting machines, so that fabric rolling machines or circular knitting machines that originally did not have wireless remote control functions can have wireless remote control functions.

[0011] In use, when any of the function buttons on the wireless transmitting unit is triggered, the wireless transmitting unit will send a corresponding wireless control signal to the wireless receiving unit. The wireless receiving unit controls the signal output switch corresponding to the function button according to the received wireless control signal, thereby causing the function control input signal of the corresponding function in the control unit of the fabric rolling machine or circular knitting machine to change so that the control unit of the fabric rolling machine or circular knitting machine controls the fabric rolling machine or circular knitting machine to perform the corresponding function control.

[0012] Specifically, in the momentary trigger mode, that is, when the function button is pressed to execute the corresponding function and released to stop execution:

[0013] If the control unit of the fabric rolling machine or circular knitting machine is configured such that it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function when it does not receive a signal from the corresponding control signal source, and controls the fabric rolling machine or circular knitting machine to perform the corresponding function when it receives a signal from the corresponding control signal source, then the wireless receiving unit is configured such that it controls the corresponding signal output switch to be turned off when it does not receive the wireless control signal for the corresponding function, and controls the corresponding signal output switch to be turned on when it receives the wireless control signal for the corresponding function.

[0014] If the control unit of the fabric rolling machine or circular knitting machine is configured such that when its function control input terminal receives a signal sent by the corresponding control signal source, it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function, and when it does not receive a signal sent by the corresponding control signal source, it controls the fabric rolling machine or circular knitting machine to perform the corresponding function, then the wireless receiving unit is configured such that when it does not receive the wireless control signal of the corresponding function, it controls the corresponding signal output switch to be turned on, and when it receives the wireless control signal of the corresponding function, it controls the corresponding signal output switch to be turned off.

[0015] In the self-locking trigger mode, that is, when pressing the function button executes the corresponding function and pressing the function button again stops execution:

[0016] The wireless receiving unit is configured to turn on the corresponding signal output switch when it receives the wireless control signal with the corresponding function, and to turn off the corresponding signal output switch when it receives the wireless control signal with the corresponding function again.

[0017] The function button can be a physical button or a virtual button on a touch screen;

[0018] However, under normal circumstances, when the function is triggered in a jog-style manner, the control unit of the fabric rolling machine or circular knitting machine is configured such that it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function when it does not receive a signal from the corresponding control signal source, and controls the fabric rolling machine or circular knitting machine to perform the corresponding function when it receives a signal from the corresponding control signal source, which is more in line with the actual design.

[0019] When there are multiple function buttons, there are also multiple signal output switches. The control signal sources connected to the multiple signal output switches can be the same signal source or different signal sources.

[0020] Furthermore, the wireless transmitting unit and the wireless receiving unit communicate through omnidirectional wireless communication technology; specifically, the wireless transmitting unit and the wireless receiving unit communicate through radio frequency technology.

[0021] By adopting the above technical solution, the communication between the wireless transmitting unit and the wireless receiving unit becomes more reliable and stable. The signal transmitted by the wireless transmitting unit propagates in all directions, so there is no need for the wireless transmitting unit and the wireless receiving unit to keep their lines of sight in order to achieve communication.

[0022] Furthermore, the wireless receiving unit includes a wireless receiving module and a relay. The number of relays matches the number of function buttons, and the contact switches on the relays form the signal output switches. The wireless receiving module can wirelessly communicate with the wireless transmitting unit and control the energization and de-energization of the coils of the corresponding relays according to the received wireless control signals.

[0023] By adopting the above technical solution, the wireless receiving unit becomes more reasonable. The wireless receiving module can control the energization and de-energization of the coil of the corresponding relay according to the received wireless control signal. The energization and de-energization of the coil of the relay can control the opening and closing of its switch contacts. That is, the wireless receiving module can control the opening and closing of the signal output switch according to the received wireless control signal.

[0024] Of course, the wireless receiving module and the relay can be in a one-to-one manner, that is, multiple wireless receiving modules are provided and each corresponds to a relay, with one wireless receiving module used to control only one relay; the wireless receiving module and the relay can also be in a one-to-many manner, that is, one wireless receiving module is provided and one wireless receiving module is used to control multiple relays.

[0025] Furthermore, the normally open or normally closed switch on the relay forms the signal output switch.

[0026] 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.

[0027] The above technical solution makes the signal output switch more reasonable. Whether the signal output switch is a normally open switch or a normally closed switch on the relay needs to be selected by the user according to the actual use situation.

[0028] For example, if the wireless receiving module controls the corresponding relay coil to be energized when it receives the wireless control signal, and the control unit of the fabric rolling machine or circular knitting machine is configured to not control the fabric rolling machine or circular knitting machine to perform the corresponding function when it does not receive the signal sent by the corresponding control signal source, and controls the fabric rolling machine or circular knitting machine to perform the corresponding function when it receives the signal sent by the corresponding control signal source, then the normally open switch of the relay becomes the signal output switch;

[0029] If, when the wireless receiving module receives the wireless control signal, it controls the corresponding relay coil to be energized, and the control unit of the fabric rolling machine or circular knitting machine is configured such that when the function control input terminal receives the signal sent by the corresponding control signal source, it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function, and when it does not receive the signal sent by the corresponding control signal source, it controls the fabric rolling machine or circular knitting machine to perform the corresponding function, then the normally open switch of the relay becomes the signal output switch, and the normally closed switch of the relay becomes the signal output switch.

[0030] Furthermore, the control signal source is configured to be high or low; specifically, the high level is generally 24V and the low level is 0V.

[0031] The above technical solution makes the control circuit more reasonable; whether the control signal source is configured to be high or low level needs to be configured by the user according to the actual use scenario, and the control signal source is usually configured to be low level.

[0032] A fabric rolling machine circuit, used in a fabric rolling machine, includes the control circuit described above, wherein the second terminal of the signal output switch is used to connect to the function control input terminal of the corresponding function on the control unit of the fabric rolling machine.

[0033] By adopting the above technical solution, the circuit of the fabric rolling machine is made more reasonable, enabling it to have wireless remote control function. Users can operate the wireless transmitting unit at any position within the communication range of both the wireless transmitting unit and the wireless receiving unit to control the fabric rolling machine, which is convenient for users, especially when debugging the machine.

[0034] Furthermore, the function buttons include at least one of a fabric pulling button, a fabric rolling button, a forward rotation button, and a reverse rotation button;

[0035] When the wireless transmitting unit is equipped with a fabric pulling button, the signal output switch includes a fabric pulling signal output switch, and the second end of the fabric pulling signal output switch is used to connect to the fabric pulling function control input terminal on the control unit of the fabric rolling machine.

[0036] When the wireless transmitting unit is equipped with a fabric roll button, the signal output switch includes a fabric roll signal output switch, and the second end of the fabric roll signal output switch is used to connect to the fabric roll function control input terminal on the control unit of the fabric roll machine.

[0037] When the wireless transmitting unit is equipped with a forward rotation button, the signal output switch includes a forward rotation signal output switch, and the second end of the forward rotation signal output switch is used to connect to the forward rotation function control input terminal on the control unit of the fabric rolling machine.

[0038] When the wireless transmitting unit is equipped with a reverse button, the signal output switch includes a reverse signal output switch, and the second end of the reverse signal output switch is used to connect to the reverse function control input terminal on the control unit of the fabric rolling machine.

[0039] By adopting the above technical solution, the circuit of the fabric rolling machine becomes more reasonable;

[0040] When the fabric pulling button is provided, when the user presses the fabric pulling button on the wireless transmitting unit, the wireless transmitting unit sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit controls the fabric pulling signal output switch to operate, so that the fabric rolling function control input terminal on the control unit of the fabric rolling machine receives the signal sent by the corresponding control signal source, so that the control unit of the fabric rolling machine controls the fabric rolling machine to perform the fabric pulling operation mode.

[0041] When the fabric roll button is provided, when the user presses the fabric roll button on the wireless transmitting unit, the wireless transmitting unit sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit controls the fabric roll signal output switch to operate, so that the fabric roll function control input terminal on the control unit of the fabric roll machine receives the signal sent by the corresponding control signal source, so that the control unit of the fabric roll machine controls the fabric roll machine to perform the fabric roll operation mode.

[0042] When the forward rotation button is provided, when the user presses the forward rotation button on the wireless transmitting unit, the wireless transmitting unit sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit controls the forward rotation signal output switch to operate, so that the forward rotation function control input terminal on the control unit of the fabric rolling machine receives the signal sent by the corresponding control signal source, so that the control unit of the fabric rolling machine controls the forward rotation of the fabric rolling machine drive components such as the motor, usually controlling the forward rotation of the relevant drive components in the current working mode.

[0043] When the reverse button is provided, when the user presses the reverse button on the wireless transmitting unit, the wireless transmitting unit sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit controls the reverse signal output switch to operate, so that the reverse function control input terminal on the control unit of the fabric rolling machine receives the signal sent by the corresponding control signal source, so that the control unit of the fabric rolling machine controls the fabric rolling machine drive components such as the motor to reverse, usually controlling the relevant drive components to reverse in the current working mode;

[0044] When the fabric pulling button and / or the fabric rolling button are provided, the forward rotation button and the reverse rotation button are usually provided;

[0045] Furthermore, when the fabric pull button and / or the fabric roll button are pressed, the corresponding signal output switch is activated and held. When the fabric pull button and / or the fabric roll button are pressed again, the corresponding signal output switch is reset. When the forward and reverse buttons are pressed, the corresponding signal output switches are activated. When the forward and reverse buttons are released, the corresponding signal output switches are reset.

[0046] The actual operation is as follows:

[0047] After the user presses the fabric-pulling button, pressing and holding the forward or reverse button will cause the fabric-pulling roller's drive mechanism to rotate forward or reverse. Releasing the forward or reverse button will stop the fabric-pulling roller's drive mechanism from rotating. When the user presses the fabric-pulling button again, even if the forward or reverse button is pressed, the fabric-pulling roller's drive mechanism will not rotate.

[0048] After the user presses the fabric roll button, pressing and holding the forward or reverse button will cause the fabric roll roller to rotate forward or reverse. Releasing the forward or reverse button will stop the fabric roll roller from rotating. When the user presses the fabric roll button again, even if the forward or reverse button is pressed, the fabric roll roller will not rotate.

[0049] Of course, the cloth pulling button and the cloth rolling button can be omitted, and only the forward and reverse buttons can be provided; the operation method can also be modified according to actual needs, and the structure can be modified to adapt to the operation method. For example, in the selection of the signal output switch, it can be a self-locking type or a momentary type, etc.

[0050] Furthermore, the control unit of the fabric rolling machine adopts a PLC or a microcontroller.

Of course, the user can choose to press or hold the button. If it is pressed, the speed increases by one point each time it is pressed; if it is held, the speed continues to increase after being pressed until the user releases the button.

[0066] When the deceleration button is provided, when the user presses the deceleration button on the wireless transmitting unit, the wireless transmitting unit sends a corresponding wireless control signal.

[0108] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0109] See Figures 1 to 3 This utility model provides a control circuit for use on a fabric rolling machine or circular knitting machine, comprising:

[0110] A wireless transmitting unit 1 is provided with at least one function button 101, and the wireless transmitting unit 1 sends a corresponding wireless control signal according to the operation of the function button 101.

[0111] The wireless receiving unit 2 has a signal output switch 201 that matches the number of function buttons 101. The wireless receiving unit 2 can wirelessly communicate with the wireless transmitting unit 1 and control the on / off state of the corresponding signal output switch 201 according to the received wireless control signal. The first end 201-1 of the signal output switch 201 is used to connect to the control signal source 3, and the second end 201-2 of the signal output switch 201 is used to connect to the function control input terminal 401 of the corresponding function on the control unit 4 of the fabric rolling machine or circular knitting machine.

[0112] By adopting the above technical solution, since the wireless transmitting unit 1 and the wireless receiving unit 2 communicate wirelessly, the user can operate the wireless transmitting unit 1 at any position within the communication range of the two to control the rolling machine or circular knitting machine, which is convenient for the user, especially when debugging the machine.

[0113] Furthermore, the wireless receiving unit 2 transmits the corresponding signal to the control unit 4 of the fabric rolling machine or circular knitting machine by controlling the on / off state of the signal output switch 201. The original operation buttons on the fabric rolling machine or circular knitting machine also transmit the corresponding signal to the control unit 4 of the fabric rolling machine or circular knitting machine by controlling their on / off state. Therefore, the signal output switch 201 in the wireless receiving unit 2 only needs to be connected in parallel to the operation button of the corresponding function. The installation is simple and it is also convenient for later maintenance and replacement. Moreover, it can modify the existing fabric rolling machine or circular knitting machine, so that the fabric rolling machine or circular knitting machine that originally did not have wireless remote control function can have wireless remote control function.

[0114] In use, when any of the function buttons 101 on the wireless transmitting unit 1 is triggered, the wireless transmitting unit 1 will send a corresponding wireless control signal to the wireless receiving unit 2. The wireless receiving unit 2 will control the signal output switch 201 corresponding to the function button 101 to operate according to the received wireless control signal, thereby causing the signal of the corresponding function control input terminal 401 in the control unit 4 of the fabric rolling machine or circular knitting machine to change so that the control unit 4 of the fabric rolling machine or circular knitting machine controls the fabric rolling machine or circular knitting machine to perform the corresponding function control.

[0115] Specifically, in the momentary trigger mode, that is, when function button 101 is pressed to execute the corresponding function and function button 101 is released to stop execution:

[0116] If the control unit 4 of the fabric rolling machine or circular knitting machine is configured such that when it does not receive a signal from the corresponding control signal source 3, it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function, and when it receives a signal from the corresponding control signal source 3, it controls the fabric rolling machine or circular knitting machine to perform the corresponding function, then the wireless receiving unit 2 is configured such that when it does not receive the wireless control signal for the corresponding function, it controls the corresponding signal output switch 201 to open, and when it receives the wireless control signal for the corresponding function, it controls the corresponding signal output switch 201 to open.

[0117] If the control unit 4 of the fabric rolling machine or circular knitting machine is configured such that when its function control input terminal 401 receives a signal sent by the corresponding control signal source 3, it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function, and when it does not receive a signal sent by the corresponding control signal source 3, it controls the fabric rolling machine or circular knitting machine to perform the corresponding function, then the wireless receiving unit 2 is configured such that when it does not receive the wireless control signal of the corresponding function, it controls the corresponding signal output switch 201 to be turned on, and when it receives the wireless control signal of the corresponding function, it controls the corresponding signal output switch 201 to be turned off.

[0118] In the self-locking trigger state, that is, when pressing function button 101 executes the corresponding function and pressing function button 101 again stops execution:

[0119] The wireless receiving unit 2 is configured to turn on the corresponding signal output switch 201 when it receives the wireless control signal with the corresponding function, and to turn off the corresponding signal output switch 201 when it receives the wireless control signal with the corresponding function again.

[0120] The function button 101 can be a physical button or a virtual button on a touch screen;

[0121] However, under normal circumstances, when the function is triggered in a jog-type manner, the control unit 4 of the fabric rolling machine or circular knitting machine is configured such that when the function control input terminal 401 on it does not receive a signal sent by the corresponding control signal source 3, it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function, and when it receives a signal sent by the corresponding control signal source 3, it controls the fabric rolling machine or circular knitting machine to perform the corresponding function, which is more in line with the actual design.

[0122] When multiple function buttons 101 are provided, multiple signal output switches 201 are also provided. The control signal sources 3 connected to the multiple signal output switches 201 can be the same signal source or different signal sources.

[0123] Furthermore, the wireless transmitting unit 1 and the wireless receiving unit 2 communicate with each other through omnidirectional wireless communication technology. Specifically, the wireless transmitting unit 1 and the wireless receiving unit 2 communicate with each other through radio frequency technology.

[0124] By adopting the above technical solution, the communication between the wireless transmitting unit 1 and the wireless receiving unit 2 becomes more reliable and stable. The signal transmitted by the wireless transmitting unit 1 is omnidirectional, so communication can be achieved without the wireless transmitting unit 1 and the wireless receiving unit 2 maintaining eye contact.

[0125] Furthermore, the wireless receiving unit 2 includes a wireless receiving module 202 and a relay 203. The number of relays 203 matches the number of function buttons 101, and the contact switches on the relays 203 form the signal output switches 201. The wireless receiving module 202 can wirelessly communicate with the wireless transmitting unit 1 and control the energization and de-energization of the coil of the corresponding relay 203 according to the received wireless control signals.

[0126] By adopting the above technical solution, the wireless receiving unit 2 is made more reasonable. The wireless receiving module 202 can control the energization and de-energization of the coil of the corresponding relay 203 according to the received wireless control signal. The energization and de-energization of the coil of the relay 203 can control the opening and closing of its switch contacts. That is, the wireless receiving module 202 can control the opening and closing of the signal output switch 201 according to the received wireless control signal.

[0127] Of course, see Figure 2 The wireless receiving module 202 and the relay 203 can be one-to-one, that is, multiple wireless receiving modules 202 are provided and each corresponds one-to-one with a relay 203, and one wireless receiving module 202 is used to control only one relay 203; see reference Figure 1 The wireless receiving module 202 and the relay 203 can also be in a one-to-many form, that is, one wireless receiving module 202 is provided, and one wireless receiving module 202 is used to control multiple relays 203.

[0128] Furthermore, the normally open or normally closed switch on the relay 203 is configured as the signal output switch 201.

[0129] 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.

[0130] The above technical solution makes the signal output switch 201 more reasonable. Whether the signal output switch 201 adopts the normally open switch or the normally closed switch on the relay 203 needs to be selected by the user according to the actual use situation.

[0131] For example, if the wireless receiving module 202 controls the corresponding relay 203 coil to be energized when it receives the wireless control signal, and the control unit 4 of the fabric rolling machine or circular knitting machine is configured to not control the fabric rolling machine or circular knitting machine to perform the corresponding function when it does not receive the signal sent by the corresponding control signal source 3, and controls the fabric rolling machine or circular knitting machine to perform the corresponding function when it receives the signal sent by the corresponding control signal source 3, then the normally open switch of the relay 203 becomes the signal output switch 201;

[0132] If, when the wireless receiving module 202 receives the wireless control signal, it controls the coil of the corresponding relay 203 to be energized, and the control unit 4 of the fabric rolling machine or circular knitting machine is configured to receive a signal sent by the corresponding control signal source 3, it does not control the fabric rolling machine or circular knitting machine to perform the corresponding function; and it controls the fabric rolling machine or circular knitting machine to perform the corresponding function when it does not receive a signal sent by the corresponding control signal source 3, then the normally open switch of the relay 203 becomes the signal output switch 201, and the normally closed switch of the relay 203 becomes the signal output switch 201.

[0133] Furthermore, the control signal source 3 is configured to be high or low; specifically, under normal circumstances, the high level is 24V and the low level is 0V.

[0134] The above technical solution makes the control circuit more reasonable; whether the control signal source 3 is configured to be high or low level needs to be configured by the user according to the actual use scenario. Under normal circumstances, the control signal source 3 is configured to be low level.

[0135] See Figures 1 to 2 A fabric rolling machine circuit, used in a fabric rolling machine, includes the control circuit described above, wherein the second terminal 201-2 of the signal output switch 201 is connected to the function control input terminal 401 of the corresponding function on the control unit 4 of the fabric rolling machine.

[0136] By adopting the above technical solution, the circuit of the fabric rolling machine is made more reasonable, enabling it to have wireless remote control function. Users can operate the wireless transmitting unit 1 at any position within the communication range of the wireless transmitting unit 1 and the wireless receiving unit 2 to control the fabric rolling machine, which is convenient for users, especially when debugging the machine.

[0137] Furthermore, the function button 101 includes at least one of the following: a fabric pulling button 101-1, a fabric rolling button 101-2, a forward rotation button 101-3, and a reverse rotation button 101-4;

[0138] When the wireless transmitting unit 1 is equipped with a fabric pulling button 101-1, the signal output switch 201 includes a fabric pulling signal output switch 201-3, and the second end 201-2 of the fabric pulling signal output switch 201-3 is used to connect to the fabric pulling function control input end 401 on the control unit 4 of the fabric rolling machine.

[0139] When the wireless transmitting unit 1 is equipped with a fabric roll button 101-2, the signal output switch 201 includes a fabric roll signal output switch 201-4, and the second end 201-2 of the fabric roll signal output switch 201-4 is used to connect to the fabric roll function control input end 401-2 on the control unit 4 of the fabric roll machine.

[0140] When the wireless transmitting unit 1 is equipped with a forward rotation button 101-3, the signal output switch 201 includes a forward rotation signal output switch 201-5, and the second end 201-2 of the forward rotation signal output switch 201-5 is used to connect to the forward rotation function control input end 401-3 on the control unit 4 of the fabric rolling machine.

[0141] When the wireless transmitting unit 1 is equipped with a reverse button 101-4, the signal output switch 201 includes a reverse signal output switch 201-6, and the second end 201-2 of the reverse signal output switch 201-6 is used to connect to the reverse function control input end 401-4 on the control unit 4 of the fabric rolling machine.

[0142] By adopting the above technical solution, the circuit of the fabric rolling machine becomes more reasonable;

[0143] When the fabric pulling button 101-1 is provided, when the user presses the fabric pulling button 101-1 on the wireless transmitting unit 1, the wireless transmitting unit 1 sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit 2 controls the fabric pulling signal output switch 201-3 to operate, so that the fabric rolling function control input terminal 401-2 on the control unit 4 of the fabric rolling machine receives the signal sent by the corresponding control signal source 3, so that the control unit 4 of the fabric rolling machine controls the fabric rolling machine to perform the fabric pulling operation mode.

[0144] When the fabric roll button 101-2 is provided, when the user presses the fabric roll button 101-2 on the wireless transmitting unit 1, the wireless transmitting unit 1 sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit 2 controls the fabric roll signal output switch 201-4 to operate, so that the fabric roll function control input terminal 401-2 on the control unit 4 of the fabric roll machine receives the signal sent by the corresponding control signal source 3, so that the control unit 4 of the fabric roll machine controls the fabric roll machine to perform the fabric roll operation mode.

[0145] When the forward rotation button 101-3 is provided, when the user presses the forward rotation button 101-3 on the wireless transmitting unit 1, the wireless transmitting unit 1 sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit 2 controls the forward rotation signal output switch 201-5 to operate, so that the forward rotation function control input terminal 401-3 on the control unit 4 of the fabric rolling machine receives the signal sent by the corresponding control signal source 3, so that the control unit 4 of the fabric rolling machine controls the forward rotation of the fabric rolling machine drive components such as the motor, usually controlling the forward rotation of the relevant drive components in the current working mode;

[0146] When the reverse button 101-4 is provided, when the user presses the reverse button 101-4 on the wireless transmitting unit 1, the wireless transmitting unit 1 sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit 2 controls the reverse signal output switch 201-6 to operate, so that the reverse function control input terminal 401-4 on the control unit 4 of the fabric rolling machine receives the signal sent by the corresponding control signal source 3, so that the control unit 4 of the fabric rolling machine controls the fabric rolling machine drive components such as the motor to reverse, usually controlling the relevant drive components to reverse in the current working mode;

[0147] When the fabric pulling button 101-1 and / or the fabric rolling button 101-2 are provided, the forward rotation button 101-3 and the reverse rotation button 101-4 are usually provided.

[0148] Furthermore, when the fabric pulling button 101-1 and / or the fabric rolling button 101-2 are pressed, the corresponding signal output switch is activated and held. When the fabric pulling button 101-1 and / or the fabric rolling button 101-2 are pressed again, the corresponding signal output switch is reset. When the forward rotation button 101-3 and the reverse rotation button 101-4 are pressed, the corresponding signal output switch is activated. When the forward rotation button 101-3 and the reverse rotation button 101-4 are released, the corresponding signal output switch is reset.

[0149] The actual operation is as follows:

[0150] After the user presses the fabric-pulling button 101-1, pressing and holding the forward rotation button 101-3 or the reverse rotation button 101-4 will cause the fabric-pulling roller's drive component to rotate forward or reverse. Releasing the forward rotation button 101-3 or the reverse rotation button 101-4 will stop the fabric-pulling roller's drive component from rotating. When the user presses the fabric-pulling button 101-1 again, even if the forward rotation button 101-3 or the reverse rotation button 101-4 is also pressed, the fabric-pulling roller's drive component will not rotate.

[0151] After the user presses the fabric rolling button 101-2, pressing and holding the forward rotation button 101-3 or the reverse rotation button 101-4 will cause the fabric rolling roller to rotate forward or backward. Releasing the forward rotation button 101-3 or the reverse rotation button 101-4 will stop the fabric rolling roller from rotating. When the user presses the fabric rolling button 101-2 again, even if the forward rotation button 101-3 or the reverse rotation button 101-4 is pressed, the fabric rolling roller will not rotate.

[0152] Of course, the cloth-pulling button 101-1 and the cloth-rolling button 101-2 can be omitted, and only the forward button 101-3 and the reverse button 101-4 can be provided. The operation method can also be modified according to actual needs, and the structure can be modified to adapt to the operation method. For example, in the selection of the signal output switch 201, it can be a self-locking type or a jog type, etc.

[0153] Furthermore, the control unit 4 of the fabric rolling machine adopts a PLC or a single-chip microcomputer.

[0154] By adopting the above technical solution, the control unit 4 of the fabric rolling machine becomes more reasonable.

Of course, the user can choose to press or hold the button. If it is pressed, the speed increases by one point each time it is pressed; if it is held, the speed continues to increase after it is pressed until the user releases the button.

[0169] When the deceleration button 101-7 is provided, when the user presses the deceleration button 101-7 on the wireless transmitting unit 1, the wireless transmitting unit 1 sends a corresponding wireless control signal. After receiving the wireless control signal, the wireless receiving unit 2 controls the deceleration signal output switch 201-9 to operate, thereby enabling the deceleration function control input terminal 401-7 on the control unit 4 of the circular knitting machine to receive the signal sent by the corresponding control signal source 3, so that the control unit 4 of the circular knitting machine can control the circular knitting machine to decelerate its running speed based on the existing speed. Of course, the user can choose to press or hold the button. If it is pressed, the speed decreases by a little each time it is pressed; if it is held, the speed continues to decrease until the user releases the button.
