Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0048] In order to increase the cotton supply speed and meet the needs of multi-variety small-batch textiles and high production, the present application relates to a multi-channel cotton supply programmable control system, which controls multiple disc cotton pickers to supply cotton to multiple multi-bin cotton mixing machines in different cotton flow directions through multiple two-way distributors according to raw materials and time periods.

[0049] See also Figures 1 to 4 , which shows the layout diagram of multiple disc cotton pluckers, multiple two-way distributors and multiple multi-bin cotton mixers involved in the multi-way cotton supply programmable control system.

[0050] Among them, multiple two-way distributors are located between multiple disc cotton pluckers and multiple multi-bin cotton mixers.

[0051] When the multi-bin cotton mixing machine needs cotton (for example, the cotton storage capacity of the multi-bin cotton mixing machine is lower than the set standard amount), a cotton request signal is output to the disc plucking machine. After the disc plucking machine plucking the cotton, it is transported to the set multi-bin cotton mixing machine according to the cotton transport channel opened by the two-way distributor, and then transported to the next stage, and finally the cotton carding machine outputs the cotton strips.

[0052] In some embodiments of the present application, the two-way cotton distribution or one-way cotton distribution of each two-way distributor is controlled by PLC 10 to control different cotton flow directions of cotton supplied to the multi-bin cotton mixing machine.

[0053] See also Figure 1 , which shows three disc pluckers (marked as disc plucker 61, disc plucker 62 and disc plucker 63), three two-way distributors (marked as two-way distributor 71, two-way distributor 72 and two-way distributor 73) and two multi-bin cotton mixers (marked as multi-bin cotton mixer 81 and multi-bin cotton mixer 82).

[0054] Among them, see Figure 3 The structure of one of the two-way distributors 71 is shown in the figure, and the two-way distributor 71 includes a cotton feeding inlet 711, a first cotton feeding outlet 712, a second cotton feeding outlet 713, a first rocking plate valve (not shown, but marked as 1A for ease of description) and a second rocking plate valve (not shown, but marked as 1B for ease of description).

[0055] The first rocking plate valve 1A is located between the cotton feeding inlet 711 and the first cotton delivery outlet 712. When the first rocking plate valve 1A is opened, a first cotton delivery channel from the cotton feeding inlet 711 to the first cotton delivery outlet 712 is formed, so that the disc plucker 61 supplies cotton to the multi-bin mixer 81 through the first cotton delivery channel (see Figure 1 ).

[0056] The second rocking plate valve 1B is located between the cotton feeding inlet 711 and the second cotton feeding outlet 712. When the second rocking plate valve 1B is opened, a second cotton feeding passage from the cotton feeding inlet 711 to the second cotton feeding outlet 713 is formed, so that the disc plucker 61 supplies cotton to the multi-bin mixer 82 through the second cotton feeding passage (see Figure 1 ).

[0057] Therefore, when the disc plucking machine 61 grabs the raw material varieties, if the first rocking plate valve 1A and the second rocking plate valve 1B are both opened, cotton is supplied to the multi-bin cotton mixing machine 81 through the first cotton delivery channel of the two-way distributor 71, and cotton is also supplied to the multi-bin cotton mixing machine 82 through the second cotton delivery channel of the two-way distributor 71, thereby realizing two-way cotton supply.

[0058] If the first rocking plate valve 1A is opened and the second rocking plate valve 1B is closed, cotton is supplied to the multi-bin cotton mixer 81 through the first cotton delivery channel of the two-way distributor 71 .

[0059] If the first rocking plate valve 1A is closed and the second rocking plate valve 1B is opened, cotton is supplied to the multi-bin cotton mixer 82 through the second cotton delivery channel of the two-way distributor 71 .

[0060] It is possible to set which disc cotton plucking machine corresponds to which multi-bin cotton mixing machine according to demand, so as to control the opening / closing of the cotton delivery channels corresponding to multiple two-way distributors (i.e., the opening / closing of the first rocking plate valve and / or the second rocking plate valve corresponding to the two-way distributors) through PLC 10 to realize cotton supply in the corresponding cotton flow direction.

[0061] It should be noted that the start and stop of the disc plucking machine needs to be combined with whether the corresponding cotton flow direction is open and whether the multi-bin cotton mixer in the corresponding cotton flow direction sends a cotton request signal to the disc plucking machine.

[0062] For example, see Figure 1 As shown, when the first rocker valve 1A of the two-way distributor 71 is opened and the multi-bin cotton mixer 81 sends a cotton request signal to the disc plucking machine 61, the disc plucking machine 61 starts to plucking cotton.

[0063] When the first rocking plate valve 1A of the two-way distributor 71 is opened and the second rocking plate valve 1B is also opened, and the multi-bin cotton mixers 81 and 82 send cotton request signals to the disc plucking machine 61 respectively, the disc plucking machine 61 starts to plucking cotton.

[0064] When the first rocker valve 2B of the two-way distributor 72 is opened and the multi-bin cotton mixer 82 sends a cotton request signal to the disc plucking machine 62, the disc plucking machine 62 starts to plucking cotton.

[0065] When the second rocking plate valve 2B of the two-way distributor 72 is opened and the second rocking plate valve 3B of the two-way distributor 73 is also opened, and the multi-bin cotton mixer 82 sends cotton request signals to the disc cotton pickers 62 and 63 respectively, the disc cotton pickers 62 and 63 start to pick cotton respectively.

[0066] As follows, reference Figures 1 to 4 , describing the cotton supply in different cotton flow directions.

[0067] See also Figure 1 The disc plucking machine 61 corresponds to the two-way distributor 71 , the disc plucking machine 62 corresponds to the two-way distributor 72 , and the disc plucking machine 63 corresponds to the two-way distributor 73 .

[0068] The cotton delivery inlet of the two-way distributor 71 is connected to the disc plucker 61, the first cotton delivery outlet is connected to the multi-bin cotton mixer 81 through the first rocking plate valve 1A, and the second cotton delivery outlet is connected to the multi-bin cotton mixer 82 through the second rocking plate valve 1B.

[0069] The cotton delivery inlet of the two-way distributor 72 is connected to the disc plucker 62, the first cotton delivery outlet is connected to the multi-bin cotton mixer 81 through the first rocking plate valve 2A, and the second cotton delivery outlet is connected to the multi-bin cotton mixer 82 through the second rocking plate valve 2B.

[0070] The cotton delivery inlet of the two-way distributor 73 is connected to the disc plucker 63, the first cotton delivery outlet is connected to the multi-bin cotton mixer 81 through the first rocking plate valve 3A, and the second cotton delivery outlet is connected to the multi-bin cotton mixer 82 through the second rocking plate valve 3B.

The three disc cotton pluckers supply cotton to the multi-bin cotton mixer 81 at the same time, thereby increasing the cotton supply speed.

[0074] High-speed cotton picking can efficiently change multiple varieties for cotton picking to meet the textile needs of small batches and multiple raw material varieties. After quickly completing the cotton picking and blending of one variety, it can quickly start the cotton picking and blending of the next variety.

[0091] The disc plucker 63 can be controlled to plucking cotton, and the second rocker valve 3B of the two-way distributor 73 can be controlled to open. The disc plucker 63 supplies cotton to the multi-bin cotton mixer 83 through the second cotton delivery channel of the two-way distributor 73, thereby increasing the cotton supply speed.

[0120] (2) If cotton is required in the multi-bin cotton mixing machine 82, perform the following operations.

[0121] The disc cotton plucker 61 and the disc cotton plucker 62 can be controlled to pick cotton respectively, and the first rocking plate valve 1A and the second rocking plate valve 1B of the two-way distributor 71 can be controlled to open, the first rocking plate valve 2A and the second rocking plate valve 2B of the two-way distributor 72 can be controlled to open, the first rocking plate valve 3A and the second rocking plate valve 3B of the two-way distributor 73 can be controlled to open, the second rocking plate valve 4B of the two-way distributor 74 can be controlled to open, and the first rocking plate valve 5A of the two-way distributor 75 can be controlled to open.

[0122] The disc cotton plucking machine 61 can supply cotton to the multi-bin cotton mixing machine 82 through the first cotton feeding channel of the two-way distributor 71 and the second cotton feeding channel of the two-way distributor 74; the disc cotton plucking machine 61 can supply cotton to the multi-bin cotton mixing machine 82 through the second cotton feeding channel of the two-way distributor 71 and the first cotton feeding channel of the two-way distributor 75.

[0123] The disc cotton plucking machine 62 can supply cotton to the multi-bin cotton mixing machine 82 through the first cotton feeding channel of the two-way distributor 71 and the second cotton feeding channel of the two-way distributor 74; the disc cotton plucking machine 62 also supplies cotton to the multi-bin cotton mixing machine 82 through the second cotton feeding channel of the two-way distributor 71 and the first cotton feeding channel of the two-way distributor 75.

[0124] The disc cotton plucking machine 62 can supply cotton to the multi-bin cotton mixing machine 82 through the first cotton feeding channel of the two-way distributor 72 and the second cotton feeding channel of the two-way distributor 74; the disc cotton plucking machine 62 can supply cotton to the multi-bin cotton mixing machine 82 through the second cotton feeding channel of the two-way distributor 72 and the first cotton feeding channel of the two-way distributor 75.

[0125] The disc cotton plucking machine 63 can supply cotton to the multi-bin cotton mixing machine 82 through the first cotton feeding channel of the two-way distributor 73 and the second cotton feeding channel of the two-way distributor 74. The disc cotton plucking machine 63 can supply cotton to the multi-bin cotton mixing machine 82 through the second cotton feeding channel of the two-way distributor 73 and the first cotton feeding channel of the two-way distributor 75.

[0126] As above Figure 4 The cotton conveying channel shown in the figure is formed by combining the cotton conveying channels of two two-way distributors connected in series. Of course, the number of two-way distributors connected in series is not limited to two.

[0127] Different from Figures 1 to 4 Other numbers of disc pluckers, two-way distributors and multi-bin blenders shown in are also possible and are not listed here.

[0128] The first cotton delivery channel and the second cotton delivery channel of the two-way distributor specifically correspond to which multi-bin cotton mixing machine and which disc cotton plucking machine, or which cotton delivery channels formed by the combination of the two-way distributors specifically correspond to which multi-bin cotton mixing machine and which disc cotton plucking machine, need to be set according to actual needs.

[0129] In order to realize the closing / opening of the first rocking valve and the second rocking valve in the two-way distributor, the present application involves multiple groups of relays, each group of relays includes a first relay and a second relay, wherein the first relay corresponds to the first rocking valve and the second relay corresponds to the second rocking valve.

[0130] When the first relay is energized / de-energized, the first rocker valve is opened / closed, and when the second relay is energized / de-energized, the second rocker valve is opened / closed.

[0131] The number of multiple groups of relays is consistent with the number of multiple two-way distributors.

[0132] In the above reference Figures 1 to 4 After the layout structure of the disc cotton plucking machine, the two-way distributor and the multi-bin cotton mixing machine is designed, according to actual needs, the PLC 10 is used to control the energization / de-energization of the first relay and the energization / de-energization of the second relay in the corresponding group of relays, thereby correspondingly opening / closing the first cotton delivery channel and / or the second cotton delivery channel of the two-way distributor corresponding to the group of relays, and then supplying / not supplying cotton in the cotton flow direction from the corresponding disc cotton plucking machine to the corresponding multi-bin cotton mixing machine that requires cotton.

[0133] As mentioned above, when cotton is needed, in addition to opening the cotton conveying channel in the corresponding cotton flow direction, it is also necessary to start the cotton picking work of the disc cotton picking machine that supplies cotton to the multi-bin cotton mixing machine in the corresponding cotton flow direction.

[0134] The start and stop of the cotton picking operation of the disc cotton picker needs to be combined with the energization / de-energization of the coil of the first relay and / or the coil of the second relay of the two-way distributor in the corresponding cotton flow direction, and whether the multi-bin cotton mixing machine in the corresponding cotton flow direction sends a cotton request signal to the disc cotton picker.

[0135] The disc plucking machine starts the cotton plucking work only when the above two conditions are met.

[0136] For example, another normally open contact of the corresponding relay in the corresponding cotton flow direction (for example, another normally open contact KAA1 different from the normally open contact KA1 of the first relay KA1) can be connected in series to the cotton picking circuit of the disc cotton picking machine in the corresponding cotton flow direction, and the start and stop of the cotton picking of the corresponding disc cotton picking machine can be controlled based on whether a cotton request signal is received from the multi-bin cotton mixing machine in the corresponding cotton flow direction.

[0137] For example, see Figure 1 As shown, when the coil of the first relay KA1 corresponding to the first rocking plate valve 1A is energized and the multi-bin cotton mixer 81 sends a cotton request signal to the disc plucking machine 61, the disc plucking machine 61 starts to plucking cotton.

[0138] See also Figure 6 , based on Figure 1 The arrangement shown is described.

[0139] PLC 10 is a programmable logic controller, which controls the power on / off of the coils of each relay through the output point, thereby changing the cotton conveying channels of the two-way distributors, thereby changing the direction of the cotton flow.

[0140] The first relay KA1 and the second relay KA2 correspond to the two-way distributor 71 , the first relay KA3 and the second relay KA4 correspond to the two-way distributor 72 , and the first relay KA5 and the second relay KA6 correspond to the two-way distributor 73 .

[0141] See also Figure 6 , PLC 10 receives external 220V AC power, and controls the power on / off status of the first relay KA1, the second relay KA2, the first relay KA3, the second relay KA4, the first relay KA5 and the second relay KA6 according to the received cotton request signal.

[0142] See also Figure 7, which shows that the first relay KA1 corresponds to the first rocking valve 1A of the two-way distributor 71, the second relay KA2 corresponds to the second rocking valve 1B of the two-way distributor 71, the first relay KA3 corresponds to the first rocking valve 2A of the two-way distributor 72, the second relay KA4 corresponds to the second rocking valve 2B of the two-way distributor 72, the first relay KA5 corresponds to the first rocking valve 3A of the two-way distributor 73, and the second relay KA6 corresponds to the second rocking valve 3B of the two-way distributor 73.

[0143] See also Figure 6 and Figure 7 , the control process of the two-way distributor 71 is taken as an example for explanation.

[0144] When the coil of the first relay KA1 is energized, the normally open contact of the first relay KA1 is closed, and the power supply (for example, 24V DC) supplies power to the first rocking valve 1A. At this time, the first rocking valve 1A is opened, and the first cotton delivery channel of the two-way distributor 71 is opened, and cotton can be supplied through the first cotton delivery channel.

[0145] When the first relay KA1 loses power, the normally open contact of the first relay KA1 opens. At this time, the power supply (for example, 24V DC) does not supply power to the first rocking valve 1A. At this time, the first rocking valve 1A is closed, and the first cotton delivery channel of the two-way distributor 71 is closed, and cotton cannot be supplied through the first cotton delivery channel.

[0146] When the coil of the first relay KA2 is energized, the normally open contact of the first relay KA2 is closed, and the power supply (for example, 24V DC) supplies power to the first rocking valve 1B. At this time, the first rocking valve 1B is opened, and the second cotton delivery channel of the two-way distributor 71 is opened, and cotton can be supplied through the second cotton delivery channel.

[0147] When the coil of the first relay KA2 is energized, the normally open contact of the first relay KA2 is closed. At this time, the power supply (for example, 24V DC) does not supply power to the first rocking valve 1B. At this time, the first rocking valve 1B is closed, and the second cotton delivery channel of the two-way distributor 71 is closed, and cotton cannot be supplied through the second cotton delivery channel.

[0148] See also Figure 1 , there are several different cotton feeding working states as follows.

[0149] (1) Cotton feeding working status 1

[0150] The disc plucking machine 61 corresponds to the multi-bin cotton mixing machine 81, the disc plucking machine 62 corresponds to the multi-bin cotton mixing machine 82, and the disc plucking machine 63 is used as a spare.

[0151] At this time, when the multi-bin cotton mixer 81 sends a cotton request signal to the disc cotton picker 61, and the multi-bin cotton mixer 82 sends a cotton request signal to the disc cotton picker 62, PLC 10 controls the first relay KA1 to be energized (the second relay KA2 to be de-energized), and the second relay KA4 to be energized (the first relay KA3 to be de-energized), so that the disc cotton picker 61 supplies cotton to the multi-bin cotton mixer 81 through the first cotton delivery channel of the two-way distributor 71, and the disc cotton picker 62 supplies cotton to the multi-bin cotton mixer 82 through the second cotton delivery channel of the two-way distributor 73.

[0159] At this time, when the multi-bin cotton mixer 82 sends a cotton request signal to the disc cotton picker 61, and the multi-bin cotton mixer 81 sends a cotton request signal to the disc cotton picker 62, PLC 10 controls the second relay KA2 to be energized (the first relay KA1 is de-energized), and the first relay KA3 to be energized (the second relay KA4 is de-energized), so that the disc cotton picker 61 supplies cotton to the multi-bin cotton mixer 82 through the second cotton delivery channel of the two-way distributor 71, and the disc cotton picker 62 supplies cotton to the multi-bin cotton mixer 81 through the first cotton delivery channel of the two-way distributor 72.

[0160] Among them, the first relay KA5 and the second relay KA6 lose power.

[0162] The disc plucking machine 61 corresponds to the multi-bin cotton mixing machine 82 , the disc plucking machine 62 is standby, and the disc plucking machine 63 corresponds to the multi-bin cotton mixing machine 81 .

[0163] At this time, when the multi-bin cotton mixer 82 sends a cotton request signal to the disc cotton picker 61, and the multi-bin cotton mixer 81 sends a cotton request signal to the disc cotton picker 63, PLC 10 controls the second relay KA2 to be energized (the first relay KA1 is de-energized), and the first relay KA5 to be energized (the second relay KA6 is de-energized), so that the disc cotton picker 61 supplies cotton to the multi-bin cotton mixer 82 through the second cotton delivery channel of the two-way distributor 71, and the disc cotton picker 63 supplies cotton to the multi-bin cotton mixer 81 through the first cotton delivery channel of the two-way distributor 73.

[0164] Among them, the first relay KA3 and the second relay KA4 lose power.

[0166] The disc plucking machine 61 is standby, the disc plucking machine 62 corresponds to the multi-bin cotton mixing machine 81, and the disc plucking machine 63 corresponds to the multi-bin cotton mixing machine 82.

[0167] At this time, when the multi-bin cotton mixer 81 sends a cotton request signal to the disc cotton picker 62, and the multi-bin cotton mixer 82 sends a cotton request signal to the disc cotton picker 63, PLC 10 controls the first relay KA3 to be energized (the second relay KA4 to be de-energized), and the second relay KA6 to be energized (the first relay KA5 to be de-energized), so that the disc cotton picker 62 supplies cotton to the multi-bin cotton mixer 81 through the first cotton delivery channel of the two-way distributor 72, and the disc cotton picker 63 supplies cotton to the multi-bin cotton mixer 82 through the second cotton delivery channel of the two-way distributor 73.

[0168] Among them, the first relay KA1 and the second relay KA2 lose power.

[0169] (6) Cotton feeding working state 6

[0170] The disc plucking machine 61 is standby, the disc plucking machine 62 corresponds to the multi-bin cotton mixing machine 82, and the disc plucking machine 63 corresponds to the multi-bin cotton mixing machine 81.

[0171] At this time, when the multi-bin cotton mixer 81 sends a cotton request signal to the disc cotton picker 63, and the multi-bin cotton mixer 82 sends a cotton request signal to the disc cotton picker 62, PLC 10 controls the second relay KA6 to be energized (the first relay KA5 to be de-energized), and the first relay KA3 to be energized (the second relay KA4 to be de-energized), so that the disc cotton picker 63 supplies cotton to the multi-bin cotton mixer 82 through the second cotton delivery channel of the two-way distributor 73, and the disc cotton picker 62 supplies cotton to the multi-bin cotton mixer 81 through the first cotton delivery channel of the two-way distributor 72.

[0172] Among them, the first relay KA1 and the second relay KA2 lose power.

[0173] The cotton feeding working state described above is only an example. When different numbers of disc cotton pluckers, two-way distributors and multi-bin cotton mixers are set and different cotton flow directions are used to supply cotton, the cotton feeding working state will also be different accordingly.

[0174] Among them, the PLC 10 controls the opening / closing of the cotton conveying channels of each two-way distributor to realize different cotton flow direction configurations, that is, which disc cotton plucker is used to supply cotton to which multi-bin cotton mixer through which cotton conveying channel.

[0175] For the convenience of users, the multi-channel cotton supply programmable control system further includes a display screen 20 which is connected to the PLC 10 .

[0176] A variety of cotton feeding working states (not limited to the multiple cotton feeding working states described above) can be set on the display screen 20. When the corresponding cotton feeding working state is selected, cotton feeding in different cotton flow directions is executed, that is, cotton is fed from which disc cotton picking machine through which cotton transport channel to which multi-bin cotton mixing machine.

[0177] The display screen 20 is used to directly select the cotton feeding working state, control different cotton flow directions, reduce the complexity of operation, and improve the cotton feeding efficiency.

[0178] See also Figure 6 In some embodiments of the present application, the multi-channel cotton supply programmable control system also includes a switching power supply 30, which is used to convert 220V AC power into a first DC voltage (for example, 24V DC) to provide power to the display screen 20.

[0179] A first switch module 40 and a second switch module 50 are further provided between the switch power supply 30 and the 220V AC power.

[0180] The first switch module 40 is connected in series between the 220V AC power and the second switch module 50 , and the second switch module 50 is connected in series between the input ends of the first switch module 40 and the switch module 30 .

[0181] In some embodiments of the present application, the first switch module 40 may be a load switch, and the second switch module 50 may be an air switch or a circuit breaker for protecting subsequent electrical devices.

[0182] In some embodiments of the present application, the first switch module 40 may be an air switch, and the second switch module 50 may be a circuit breaker.

[0183] In order to indicate the working state (open / closed) of the cotton conveying channel of the two-way distributor, the indicator lights of the relays in each group of relays can be used for indication. For example, when the coil of the first relay KA1 is energized, the indicator light of the relay lights up, indicating that the first cotton conveying channel of the two-way distributor 71 is open, otherwise, the indicator light does not light up, indicating that the first cotton conveying channel of the two-way distributor 71 is closed.

[0184] In order to provide feedback on whether the rocking plate valve of the two-way distributor is fully opened, the PLC 10 receives a switch feedback signal of the opened rocking plate valve.

[0185] For example, a proximity switch is used to detect whether a rocking valve is fully opened. When the proximity switch is turned on, it indicates that the corresponding rocking valve is fully opened. When the proximity switch is turned off, it indicates that the rocking valve is faulty or the proximity switch is faulty, and fault handling is required.

[0186] In this case, a feedback signal is fed back through the feedback switch, and when a fault occurs, an alarm signal is output through the alarm circuit to alert the user.

[0187] In some embodiments of the present application, see Figure 6 and Figure 7 , PLC 10 controls the coil of alarm relay KA7 to be energized / de-energized, and Figure 8 The alarm circuit shown outputs an alarm signal.

[0188] For example, see Figure 1 , when only the process of the multi-bin cotton mixer 81 requiring cotton is monitored, the above combined Figure 1 As described above, the disc plucking machine 61 supplies cotton to the multi-bin cotton mixing machine 81 through the first cotton conveying channel of the two-way distributor 71, the disc plucking machine 62 supplies cotton to the multi-bin cotton mixing machine 81 through the first cotton conveying channel of the two-way distributor 72, and the disc plucking machine 63 supplies cotton to the multi-bin cotton mixing machine 81 through the first cotton conveying channel of the two-way distributor 73.

[0189] When PLC 10 controls the first rocking valve 1A of the two-way distributor 71 to open, controls the first rocking valve 2A of the two-way distributor 72 to open, and controls the first rocking valve 3A of the two-way distributor 73 to open, if the corresponding first rocking valve 1A is provided with a proximity switch I for detecting whether it is fully opened, the corresponding first rocking valve 2A is provided with a proximity switch II for detecting whether it is fully opened, and the corresponding first rocking valve 3A is provided with a proximity switch III for detecting whether it is fully opened.

[0190] When the PLC 10 output controls the first rocking valve 1A of the two-way distributor 71 to open, controls the first rocking valve 2A of the two-way distributor 72 to open, and controls the first rocking valve 3A of the two-way distributor 73 to open, if the proximity switch I detects that the first rocking valve 1A is fully opened, the proximity switch II detects that the first rocking valve 2A is fully opened, and the proximity switch III detects that the first rocking valve 3A is fully opened, the alarm relay KA7 loses power, the corresponding normally open contact is disconnected, and the alarm circuit does not output an alarm prompt.

[0191] If proximity switch I does not feedback a connection signal (for example, the first rocking valve 1A does not open to the full position, or proximity switch I itself is faulty), and / or proximity switch II does not feedback a connection signal (for example, the first rocking valve 2A does not open to the full position, or proximity switch II itself is faulty), and / or proximity switch III does not feedback a connection signal (for example, the first rocking valve 3A does not open to the full position, or proximity switch III itself is faulty), the alarm relay KA7 is energized, its corresponding normally open contact is connected, and the alarm circuit outputs an alarm prompt to remind the user to perform fault processing.

[0192] In some embodiments of the present application, Figure 8 The alarm circuit includes a buzzer H1 for outputting a sound alarm prompt. Of course, it can also output an audible and visual alarm prompt or a light alarm prompt.

[0193] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
