Description

Technical Field

[0001] This utility model relates to the field of automatic shutdown technology, and more specifically, to an automatic shutdown device for temperature control short circuit of a packaging machine. Background Technology

[0002] An automatic shutdown device for short circuit in the temperature control system of a packaging machine is a safety protection device used to automatically stop the machine from running when a short circuit or other abnormal situation occurs in the temperature control system of the packaging machine, so as to prevent equipment damage or safety accidents.

[0003] In the existing technology, during the production process of packaging machines, if one of the circuit breakers in the control center, end sealing and temperature control circuits trips automatically for some reason, it will cause the temperature controller of that circuit to cool down. This is not easily noticed by the personnel at the cake-grabbing position. It is only discovered during the initial inspection at random times, which poses a risk of defective products flowing out of the production line.

[0004] Therefore, we have made improvements to this and proposed an automatic shutdown device for temperature control short circuit in packaging machines. Utility Model Content

The alarm 709 is provided with a switch button for turning off the alarm 709.

[0046] Implementation process: During use, when one of the circuit breakers 2 trips, the circuit breaker 201 drives the drive rod 202 to rotate. The rotation of the drive rod 202, in conjunction with the drive block 303 and the drive groove 304, causes the sliding plate 302 to slide downwards on the limit block 301. The downward sliding of the sliding plate 302 presses down on the lower pressure plate 703, causing the lower pressure plate 703 to drive the connecting conductive block 704 to press the reset spring and slide downwards within the moving groove 702. The downward sliding of the conductive block 704 causes the first trapezoidal conductive block 708 and the second trapezoidal conductive block 7011 to insert into the trapezoidal groove 705 and fit tightly against it. At this time, the power supply 706 sequentially passes through the first wire 707, ... The first trapezoidal conductive block 708, conductive block 704, the second trapezoidal conductive block 7011, and the second wire 7010 supply power to the alarm 709, enabling the alarm 709 to issue an alarm to the operator, which is beneficial for timely notification of malfunctions. Through the main connection component 4 and the auxiliary connection component 5, when the circuit breaker 2 needs to be tripped, the control rod 508 is pulled. The control rod 508 drives the insert block 505 to insert into the slot 402. During insertion, the inclined surface of the insert block 505 presses against the inclined surface of the trapezoidal locking block 405, causing the trapezoidal locking block 405 to drive the moving slider 404 to press against the limit spring 406 and move into the receiving groove 403. When the slot 506 is in the trapezoidal locking block... When the trapezoidal block 405 is directly below the limit spring 406, the limit spring 406 causes the trapezoidal block 405 to insert into the slot 506 for limiting, thus ensuring that if any one circuit breaker 2 trips, the other circuit breakers 2 will also trip, thereby automatically stopping the packaging machine and improving the stability of the device. When one of the circuit breakers 2 needs to operate alone, by pulling the pull plate 408, the pull plate 408 drives the moving slider 404 to move into the receiving slot 403 via the pull rod 407. The receiving slot 403 drives the trapezoidal block 405 to move upward, so that the trapezoidal block 405 no longer limits the slot 506. Then, by pulling the control rod 508, the control rod 508 drives the square... The slider 503 drives the slot 506 to slide into the square groove 502. Finally, by rotating the blocking plate 604, the blocking plate 604 is locked into the concave groove 606, thereby blocking the control rod 508 from moving. This prevents the compression spring 504 from driving the plug block 505 to move, thus releasing the connection between the main connection component 4 and the auxiliary connection component 5. This allows the operator to operate one circuit breaker 2 without affecting the other circuit breakers 2, increasing the flexibility and adaptability of the device. The main connection component 4 and the auxiliary connection component 5 support modular design, which can be easily expanded or modified as needed without affecting the function of the existing circuit breaker 2.
