Description

Technical Field

[0001] This utility model relates to the field of feeding adjustment technology, and in particular to a feeding adjustment device for a film raw material tank. Background Technology

[0002] The raw material feeding port of the BOPP film production line is usually located far from the central control room. In the past, the operation steps before feeding raw materials were as follows: the on-site feeding personnel prepared the raw materials according to the work order, the central control room operator manually operated the switching tank, and after the tank switching was completed, the on-site feeding personnel were contacted remotely to start feeding. After feeding the raw materials into one tank, the tank needed to be switched. The on-site feeding personnel contacted the central control room personnel remotely to perform the tank switching operation. After the tank switching was confirmed, the on-site feeding personnel needed to be contacted remotely again to start feeding.

[0003] Since there are no material tank switching instructions at the feeding site, if multiple material tanks need to be fed, the switching of material tanks requires multiple communications and confirmations to ensure that the material being fed into the tank is consistent with the selected material tank. This process often takes a lot of time, which can easily increase production costs, reduce work efficiency, and also pose a certain risk of feeding errors. Utility Model Content

[0050] As described in the background section, in the prior art, switching material tanks requires multiple rounds of communication and confirmation to ensure that the current material tank is consistent with the selected material tank. This process often takes a lot of time, which can easily increase production costs, reduce work efficiency, and also pose a certain risk of material feeding errors.

[0051] Reference Figure 1 and Figure 2 In some embodiments of this utility model, a feeding adjustment device for a film raw material tank includes: a second auxiliary switch 300, a first auxiliary switch 200, a main switch 100, a control module, a status indicator light 600, and a feeding driver 700.

[0052] The material tank is equipped with a feeding driver 700, which is used to release the raw materials stored in the material tank.

[0053] The main switch 100 has a first connection terminal and a second connection terminal, and the main switch 100 has at least two connection terminals. That is, the main switch 100 can have two connection terminals or multiple connection terminals. The common terminal of the main switch 100 can be connected to a power supply.

[0054] The drive end of the main switch 100 is connected to the control module, and the first connection end of the main switch 100 is connected to the common end of the first auxiliary switch 200.

[0055] The drive end of the first auxiliary switch 200 is connected to the control module, the first communication end of the first auxiliary switch 200 is connected to the feeding driver 700, and the first communication end of the first auxiliary switch 200 is connected to the status indicator light 600. That is, the feeding driver 700 and the status indicator light 600 connected to the first communication end of the first auxiliary switch 200 are connected in parallel.

[0056] The drive end of the second auxiliary switch 300 is connected to the control module, and the common end of the second auxiliary switch 300 is connected to the second communication end of the first auxiliary switch 200. The first communication end of the second auxiliary switch 300 is connected to the feeding driver 700, and the first communication end of the second auxiliary switch 300 is connected to the status indicator light 600. That is, the feeding driver 700 and the status indicator light 600 connected to the first communication end of the second auxiliary switch 300 are connected in parallel.

[0057] The second terminal of the second auxiliary switch 300 is connected to the feeding driver 700, and the second terminal of the second auxiliary switch 300 is also connected to the status indicator light 600. That is, the feeding driver 700 and the status indicator light 600 connected to the second terminal of the second auxiliary switch 300 are connected in parallel.

[0058] In other words, except for the second connection terminal of the first sub-switch 200 which is not connected to the status indicator light 600 and the feeding driver 700, the connection terminals of the other sub-switches are each connected to the status indicator light 600 and the feeding driver 700.

[0059] The control module can adjust the connection terminals of the main switch 100, the first auxiliary switch 200, and the second auxiliary switch 300 to enable the corresponding feeding driver 700 to run and illuminate the corresponding status indicator 600.

[0060] For example, refer to Figure 2 If the material tank corresponding to the feeding driver 700 connected to the first connecting end of the first auxiliary switch 200 needs to be fed, the control module adjusts the main switch 100 to open the first connecting end (KA12-1 closed, KA12-2 open), adjusts the first auxiliary switch 200 to open the first connecting end (KA13-1 closed, KA13-2 open), and adjusts the second auxiliary switch 300 to reset, so that the feeding driver 700 connected to the first connecting end of the first auxiliary switch 200 runs, and the status indicator 600 corresponding to the feeding driver 700 lights up.

[0061] For example, refer to Figure 2 If the material tank corresponding to the feeding driver 700 connected to the first connection terminal of the second auxiliary switch 300 needs to be fed, the control module adjusts the main switch 100 to open the first connection terminal (KA12-1 closed, KA12-2 open), adjusts the first auxiliary switch 200 to open the second connection terminal (KA13-1 open, KA13-2 closed), and adjusts the second auxiliary switch 300 to open the first connection terminal (KA14-1 closed, KA14-2 open), so that the feeding driver 700 connected to the first connection terminal of the second auxiliary switch 300 runs, and the status indicator 600 corresponding to the feeding driver 700 lights up.

[0062] For example, refer to Figure 2 If the material tank corresponding to the feeding driver 700 connected to the second connection terminal of the second auxiliary switch 300 needs to be fed, the control module adjusts the main switch 100 to open the first connection terminal (KA12-1 closed, KA12-2 open), adjusts the first auxiliary switch 200 to open the second connection terminal (KA13-1 open, KA13-2 closed), and adjusts the second auxiliary switch 300 to open the second connection terminal (KA14-1 open, KA14-2 closed), so that the feeding driver 700 connected to the second connection terminal of the second auxiliary switch 300 runs, and the status indicator 600 corresponding to the feeding driver 700 lights up.

[0063] The secondary switcher can be a switching valve, and no restrictions are placed on the specific type of the secondary switcher in this embodiment.

[0064] The above scheme connects the feeding driver 700 of the raw material tank to the corresponding connection terminals of the first auxiliary switch 200 and the second auxiliary switch 300. By controlling the connection terminals of the main switch 100, the first auxiliary switch 200 and the second auxiliary switch 300 to conduct, the raw material tank that needs to be fed is determined, and the corresponding feeding driver 700 is driven to run to feed the material. The status indicator light 600 and the feeding driver 700 are connected in parallel to realize the real-time display of the currently switched tank, ensuring the long-term efficient operation of the raw material feeding work, reducing the number of remote communications, reducing the error rate, and improving the efficiency of raw material feeding and production efficiency.

[0065] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the feeding adjustment device further includes: a third auxiliary switch 400 and a fourth auxiliary switch 500.

[0066] The second connection terminal of the main switch 100 is connected to the common terminal of the third auxiliary switch 400.

[0067] The drive end of the third auxiliary switch 400 is connected to the control module, and the first communication end of the third auxiliary switch 400 is connected to the feeding driver 700 and the status indicator light 600. That is, the feeding driver 700 and the status indicator light 600 connected to the first communication end of the third auxiliary switch 400 are connected in parallel.

[0068] The drive end of the fourth auxiliary switch 500 is connected to the control module, the common end of the fourth auxiliary switch 500 is connected to the second communication end of the third auxiliary switch 400, the first communication end of the fourth auxiliary switch 500 is connected to the feeding driver 700, and the first communication end of the fourth auxiliary switch 500 is connected to the status indicator light 600. That is, the feeding driver 700 and the status indicator light 600 connected to the first communication end of the fourth auxiliary switch 500 are connected in parallel.

[0069] The second connection terminal of the fourth auxiliary switch 500 is connected to the feeding driver 700, and the second connection terminal of the fourth auxiliary switch 500 is also connected to the status indicator light 600. That is, the feeding driver 700 and the status indicator light 600 connected to the second connection terminal of the fourth auxiliary switch 500 are connected in parallel.

[0070] In other words, except for the second connection terminal of the third sub-switch 400 which is not connected to the status indicator 600 and the feeding driver 700, the connection terminals of the other sub-switches are each connected to the status indicator 600 and the feeding driver 700.

[0071] For example, refer to Figure 2 If the material tank corresponding to the feeding driver 700 connected to the first connection terminal of the third auxiliary switch 400 needs to be fed, the control module adjusts the main switch 100 to open the second connection terminal (KA12-1 is open, KA12-2 is closed), adjusts the third auxiliary switch 400 to open the first connection terminal (KA15-1 is closed, KA15-2 is open), and adjusts the fourth auxiliary switch 500 to reset, so that the feeding driver 700 connected to the first connection terminal of the third auxiliary switch 400 runs, and the status indicator 600 corresponding to the feeding driver 700 lights up.

[0072] For example, refer to Figure 2 If the material tank corresponding to the feeding driver 700 connected to the first connection terminal of the fourth auxiliary switch 500 needs to be fed, the control module adjusts the main switch 100 to open the second connection terminal (KA12-1 is open, KA12-2 is closed), adjusts the third auxiliary switch 400 to open the second connection terminal (KA15-1 is open, KA15-2 is closed), and adjusts the fourth auxiliary switch 500 to open the first connection terminal (KA16-1 is closed, KA16-2 is open), so that the feeding driver 700 connected to the first connection terminal of the fourth auxiliary switch 500 runs, and the status indicator 600 corresponding to the feeding driver 700 lights up.

[0073] For example, refer to Figure 2 If the material tank corresponding to the feeding driver 700 connected to the second connection terminal of the fourth auxiliary switch 500 needs to be fed, the control module adjusts the main switch 100 to open the second connection terminal (KA12-1 is open, KA12-2 is closed), adjusts the third auxiliary switch 400 to open the second connection terminal (KA15-1 is open, KA15-2 is closed), and adjusts the fourth auxiliary switch 500 to open the second connection terminal (KA16-1 is open, KA16-2 is closed), so that the feeding driver 700 connected to the second connection terminal of the fourth auxiliary switch 500 runs, and the status indicator 600 corresponding to the feeding driver 700 lights up.

[0074] The secondary switcher can be a switching valve, and no restrictions are placed on the specific type of the secondary switcher in this embodiment.

[0075] Similarly, through the above scheme, the feeding driver 700 of the raw material tank is connected to the corresponding connection terminals of the third auxiliary switch 400 and the fourth auxiliary switch 500. By controlling the connection terminals of the main switch 100, the third auxiliary switch 400 and the fourth auxiliary switch 500 to conduct, the raw material tank that needs to be fed is determined, and the corresponding feeding driver 700 is driven to run to feed the material. Through the parallel status indicator light 600 and the feeding driver 700, the currently switched tank can be displayed in real time, ensuring the long-term efficient operation of the raw material feeding work, reducing the number of remote communications, reducing the error rate, and improving the efficiency of raw material feeding and production efficiency.

[0076] Reference Figures 1 to 4 In some embodiments of this utility model, the feeding adjustment device further includes: an alarm module 900 and a switcher feedback module 800.

[0077] The input terminal of the switcher feedback module 800 is connected to the drive terminal of the main switcher 100, the input terminal of the switcher feedback module 800 is connected to the drive terminal of the first auxiliary switcher 200, the input terminal of the switcher feedback module 800 is also connected to the drive terminal of the second auxiliary switcher 300, and the output terminal of the switcher feedback module 800 is connected to the input terminal of the warning module 900.

[0078] The switch feedback module 800 can acquire the connection terminal conduction signal fed back by the main switch 100, the connection terminal conduction signal fed back by the first auxiliary switch 200, and the connection terminal conduction signal fed back by the second auxiliary switch 300.

[0079] In other words, the switcher feedback module 800 collects the actual switching position signal of the switcher, which can reflect the currently selected material tank in real time. Only one of multiple material tanks can be selected at a time; multiple material tanks cannot be selected. When the corresponding feeding driver 700 is selected, the corresponding status indicator light 600 lights up, indicating that the switcher switching is normal and the material tank selection is correct. When the selected feeding driver 700 does not correspond to the corresponding indicator light, it indicates that the switcher switching is abnormal, and an inspection is required.

[0080] The warning module 900 can receive the connection end conduction signal. When the conversion time of the connection end conduction signal exceeds the set time threshold, it is considered that no switcher has generated a new switching action within the set time threshold, and the tank switching may be incorrect, so a warning signal is issued.

[0081] In other words, the warning module 900 adopts a logic control circuit similar to that used for tank switching. It collects the connection signal fed back by the switcher during the tank switching process in real time. On this basis, a time relay is added to calculate the switching time. When the switching timeout occurs, the time-delay relay is activated, triggering a buzzer alarm to indicate that the currently selected tank is incorrect or faulty and requires targeted repair. This fault alarm will not disappear until the fault is eliminated and the switcher successfully switches back to normal.

That is, the first switch of the main relay 910 is connected to one end of the first switch of the second relay 930 through the second switch of the first relay 920.

[0094] The warning module 900 can receive the connection end conduction signal.
