The electrical signal input terminal 3023a is connected to the power supply, the electrical signal output terminal 3023b is connected to the power input terminal 400a, the first pin 1021 is connected to the DC power terminal 3021, the second pin 1022 is connected to the control terminal input terminal 3022a, and the control terminal output terminal 3022b is connected to the control input terminal 400b. The power supply connection includes being turned on or off. The control output terminal 400c is connected to the first input terminal 210a, and the first output terminal 210b is connected to the second input terminal 220a.

[0037] The cable protection device 10 includes a first working state and a second working state;

[0038] In the first working state, the phase power pin 1023 is connected to the electrical signal input terminal 3023a, the electrical signal output terminal 3023b is connected to the power input terminal 400a, and the phase power pin 1023 is inserted into the phase power terminal 3023; the control module 400 transmits the control command to the connection control unit 210 according to the power signal received by the power input terminal 400a, and the connection control unit 210 adjusts the locking unit 220 to lock with the first connection end 101a according to the control command;

[0039] In the second working state, the phase power pin 1023 is disconnected from the electrical signal input terminal 3023a, and the electrical signal output terminal 3023b is disconnected from the power input terminal 400a. The phase power pin 1023 is not inserted into the phase power terminal 3023. The control module 400 transmits the control command to the connection control unit 210 according to the power signal received by the power input terminal 400a. The connection control unit 210 adjusts the locking unit 220 to disengage from the first connection end 101a according to the control command.

[0040] Among them, reference Figures 1 to 6 As shown, the cable protection device 10 includes a feeding trolley 100, which comprises a body 101 and a cable 102. The body 101 is the main housing of the feeding trolley 100, and the cable 102 is a transmission line for relevant electrical signals, such as power signals. The feeding trolley 100 can be electrically connected to the shredder 300 via the cable 102, thereby transferring the material in the feeding trolley 100 to the shredder 300. Optionally, the material can be tobacco shreds, etc.

[0041] For details, please refer to Figure 1 As shown, the vehicle body 101 includes a first connecting end 101a, which can be understood as a part of the structure of the vehicle body 101. The shredder body 301 includes a second connecting end 301a, which can be understood as a part of the structure of the shredder body 301. When the first connecting end 101a and the second connecting end 301a are mechanically connected, it proves that the feeding trolley 100 and the shredder 300 are mechanically connected. Therefore, a suitable distance can be provided for the material transfer between the feeding trolley 100 and the shredder 300. Thus, when the feeding trolley 100 and the shredder 300 are electrically connected, the material transfer can be realized.

[0042] Furthermore, the cable 102 includes a cable plug 102a, which is used to connect to the socket 302 on the main body 301 of the shredder for power supply. When the cable plug 102a is connected to the socket 302, it indicates that the feeding trolley 100 and the shredder 300 are electrically connected, and material transfer can be realized, thereby realizing the normal production process; when the cable plug 102a is not connected to the socket 302, it indicates that the feeding trolley 100 and the shredder 300 are disconnected, material transfer does not continue, production stops, and in this case, equipment maintenance or repair can be performed on the feeding trolley 100 or the shredder 300.

[0043] It is important to note that if maintenance or production shutdown is required for the feeding trolley 100 and the shredder 300, they must be separated, specifically the first connecting end 101a and the second connecting end 301a. In this case, the cable plug 102a and socket 302 used for the electrical connection between the feeding trolley 100 and the shredder 300 should be disconnected. Forcibly separating the first connecting end 101a and the second connecting end 301a while the cable 102 and socket 302 are in contact will damage the cable 102, thus affecting production. If the operation relies excessively on manual operation, such errors cannot be completely avoided. Therefore, the protection device 10 provided in this embodiment of the present invention adds a locking connection module 200 and a control module 400. The locking connection module 200 contacts the cable 102, and the control module 400 adjusts the mechanical connection between the first connection end 101a and the second connection end 301a in accordance with the transmission of electrical signals in the cable 102. When the cable 102 is electrically connected to the socket 302, the first connection end 101a and the second connection end 301a are controlled to be connected, so that the feeding trolley 100 and the shredder body 301 cannot be separated. If it is necessary to separate the two, it is necessary to further check whether the cable 102 is inserted into the socket 302, thereby improving the safety of operation. When the cable 102 and the socket 302 are not electrically connected, the feeding trolley 100 and the shredder 300 can be separated as needed, that is, the first connection end 101a and the second connection end 301a are disconnected.

[0044] For details, please refer to Figures 1 to 6 As shown, please refer to the following for details. Figure 2 As shown, the cable plug 102a includes a first pin 1021, a second pin 1022, and a phase power pin 1023. See reference [link / reference needed] for details. Figure 4As shown, socket 302 includes a DC power terminal 3021, a control terminal 3022, and a phase power terminal 3023. The first pin 1021 is connected to the DC power terminal 3021, the second pin 1022 is connected to the control terminal 3022, and the phase power pin 1023 is connected to the phase power terminal 2023. Regarding the power connection, it can be understood that if the cable plug 102a is inserted into socket 302, the power connection is on; if the cable plug 102a is not inserted into socket 302, the power connection is off. Specifically, if the phase power pin 1023 is inserted into socket 302, i.e., the phase power pin 1023 is electrically connected to the phase power terminal 2023, it proves that the feeding trolley 100 is electrically connected to the shredder 300; if the phase power pin 1023 is not inserted into socket 302, i.e., the phase power pin 1023 is not electrically connected to the phase power terminal 2023, it proves that the feeding trolley 100 is not electrically connected to the shredder 300. Simultaneously, when the feeding trolley 100 is electrically connected to the shredder 300, the first pin 1021 is also connected to the DC power terminal 3021, and the second pin 1022 is also connected to the control terminal 3022. The DC power terminal 3021 is equivalent to the DC power provided by the shredder 300, such as a 24V DC power supply; the connection of the control terminal 3022 is equivalent to connecting the control module 400 into the circuit. Since the first pin 1021 and the second pin 1022 are shorted, when the cable plug 102a is inserted into the socket 302, the control module 400 can be electrically connected to the shredder 300 sequentially through the control terminal 3022, the second pin 1022, the first pin 1021, and the DC power terminal 3021. Therefore, the control module 400 can determine the current electrical connection status between the feeding trolley 100 and the shredder 300 based on the currently acquired current value, and further regulate the locking connection module 200.

[0045] Among them, the first pin 1021 and the second pin 1022 are two redundant pins in the cable plug 102a. In this embodiment of the utility model, the first pin 1021 and the second pin 1022 are shorted together. The first pin 1021 is connected to the DC power terminal 3021 and the second pin 1022 is connected to the control terminal 3022. This enables the connection of the control module 400, achieves better protection for the cable 102, and improves the overall working safety.

[0046] Furthermore, the control module 400 is electrically connected to the locking connection module 200. The locking connection module 200 includes a connection control unit 210 and a locking unit 220. The first end of the locking unit 220 is mechanically connected to the second connection end 301a, and the second end of the locking unit 220 is overlapped with the first connection end 101a. This overlapped connection includes both disengagement and tightening. Specifically, one end of the locking unit 220 is mechanically connected to the second connection end 301a, such as through a tenon-and-mortise joint or other connection methods; this embodiment does not specifically limit this. While the other end of the locking unit 220 is overlapped with the first connection end 101a, the control module 400 adjusts the second end of the locking unit 220 to disengage from the first connection end 101a or to tighten it under different circumstances. This allows the control module 400 to adjust the mechanical connection state of the feeding trolley 100 and the shredder 300.

[0047] For specific connection relationships, please refer to... Figure 5 As shown, the phase power pin 1023 is connected to the electrical signal input terminal 3023a for power supply, the electrical signal output terminal 3023b is connected to the power input terminal 400a, the first pin 1021 is connected to the DC power terminal 3021 for power supply, the second pin 1022 is connected to the control terminal input terminal 3022a for power supply, and the control terminal output terminal 3022b is connected to the control input terminal 400b. The power supply connection includes being turned on or off. The control output terminal 400c is connected to the first input terminal 210a, and the first output terminal 210b is connected to the second input terminal 220a.

[0048] Specifically, the cable protection device 10 includes a first operating state and a second operating state, as shown in the reference. Figure 4 As shown, in the first working state, the first pin 1021 is electrically connected to the DC power terminal 3021, the second pin 1022 is electrically connected to the control terminal 3022, and the phase power pin 1023 is electrically connected to the phase power terminal 3023. That is, the cable plug 102a is electrically connected to the socket 302, and the pins in the cable 102a are inserted into the socket 302. The control module 400 transmits control commands to the connection control unit 210 based on the power signal received from the power input terminal 400a. The connection control unit 210 adjusts the locking unit 220 to lock the first connection end 101a according to the control commands. In other words, when the cable 102 is electrically connected to the socket 302, the control module 400 controls the feeding trolley 100 and the shredder 300 to be in a mechanically connected state, preventing the feeding trolley 100 from separating from the shredder 300 and causing damage to the cable 102. (Reference) Figure 6As shown, in the second working state, the first pin 1021 is disconnected from the DC power terminal 3021, the second pin 1022 is disconnected from the control terminal 3022, and the phase power pin 1023 is disconnected from the phase power terminal 3023. That is, the cable plug 102a is not electrically connected to the socket 302, the pins in the cable 102a are not inserted into the socket 302, the power input terminal 400a of the control module 400 does not receive the power signal, and transmits the corresponding control command to the connection control unit 210. The connection control unit 210 adjusts the locking unit 220 to release and disengage from the first connection end 101a according to the control command. In other words, when the cable 102 is not electrically connected to the socket 302, the control module 400 controls the feeding trolley 100 and the shredder 300 to be in a released state, which can separate the feeding trolley 100 and the shredder 300 without damaging the cable 102.

[0049] Optionally, when the shredder body 301 and the feeding trolley 100 need to enter the maintenance or repair state, the cable 102 is disconnected from the socket 302. In this case, the control module 400 does not receive an electrical signal through the second pin 1022 and the first pin 1021, so the control connection control unit 210 adjusts the state of the locking unit 220. Specifically, the locking unit 220 is disengaged from the first connection end 101a, thus realizing the separation of the shredder body 301 and the feeding trolley 100, thereby putting the shredder body 301 and the feeding trolley 100 into the maintenance or repair state. Furthermore, when the shredder body 301 and the feeding trolley 100 need to enter the production state, the cable plug 102a is inserted into the socket 302. In this case, the control module 400 receives the corresponding electrical signals through the second pin 1022 and the first pin 1021, and then controls the connection control unit 210 to adjust the state of the locking unit 220. Specifically, the locking unit 220 is locked with the first connection end 101a, thus realizing the mechanical connection between the shredder body 301 and the feeding trolley 100, thereby ensuring that the shredder body 301 and the feeding trolley 100 are in the production state, and the feeding trolley 100 provides relevant materials to the shredder body 301.

[0050] Optionally, the control module 400 may be a programmable logic controller (PLC). The PLC adjusts the production, maintenance, and repair status in conjunction with a pre-set program. This embodiment of the present invention does not impose specific limitations on this.

[0051] In summary, this utility model embodiment provides a cable protection device. The feeding trolley includes a main body and a cable. The main body includes a first connecting end, and the cable includes a cable plug with a first pin, a second pin, and a phase power pin. The first and second pins are short-circuited. The socket of the shredder body includes a DC power terminal, a control terminal, and a phase power terminal. The locking connection module includes a connection control unit and a locking unit. The first end of the locking unit is mechanically connected to the second connecting end of the shredder body, and the second end of the locking unit is overlapped with the first connecting end. The phase power pin is connected to the phase power terminal, the first pin is connected to the DC power terminal, and the second pin is connected to the control module via the control terminal. The control module adjusts the overlap relationship between the locking unit and the first connecting end based on the power supply connection, thereby adjusting the connection state between the feeding trolley and the shredder to ensure better cable safety. Furthermore, adjusting the mechanical connection state based on the power supply connection state between the feeding trolley and the shredder ensures better cable safety and reliable production processes.

[0052] Continue to refer to Figures 1 to 6 As shown, the cable plug 102a includes three phase power pins 1023.

[0053] For details, please refer to Figures 1 to 6 As shown, the first pin 1021 and the second pin 1022 in the cable plug 102a are redundant pins. The number of phase power pins 1023 can be three, as shown below. Figure 2 As shown, in other words, the cable plug 102a can be understood as a six-pin plug. This means that the redundant pins in the protection device 10 provided in this embodiment of the invention are short-circuited, eliminating the need to adjust the model and type of the cable plug 102a in the feeding trolley 100, and eliminating the need to adjust the cable 102, thus reducing the overall cost of the protection device 10. It should be noted that... Figure 1 Socket 302 is not shown in the diagram. Figure 3 The cable plug 102a is inserted into the socket 302. Figure 6 The cable plug 102a is not inserted into the socket 302. Optionally, the specific number of phase power pins 1023 can be adjusted according to actual needs, and this embodiment of the utility model does not impose a specific limitation on this.

[0054] Furthermore, the cable plug 102a also includes a grounding pin 1024.

[0055] For details, please refer to Figure 2 As shown, the cable plug 102a includes a grounding pin 1024, corresponding to the reference... Figure 4As shown, the socket 302 includes a grounding terminal 3024, wherein the grounding pin 1024 is electrically connected to the grounding terminal 3024 when the cable plug 102a is inserted into the socket 302.

[0056] Further reference Figures 1 to 6 As shown, the connection control unit 210 includes a relay 211, and the locking unit 220 includes a cylinder 221 and a bending lock 222; the relay 211 is electrically connected to the cylinder 221, and the cylinder 221 is mechanically connected to the bending lock 222.

[0057] Specifically, the connection control unit 210 includes a relay 211. In the first operating state, the cable plug 102a is electrically connected to the socket 302, and the relay 211 receives a corresponding electrical signal transmitted by the control module 400, thereby energizing the relay 211. When the relay 211 is energized, the cylinder 221 collects gas and inflates, referring to... Figure 3 As shown, cylinder 221 drives the bending lock 222 to fall, locking the first connecting end 101a and ensuring a mechanical connection between the first connecting end 101a and the second connecting end 301a, preventing the feeding trolley 100 and the shredder body 301 from separating. Furthermore, in the second operating state, the cable plug 102a is not in contact with the socket 302, and relay 211 does not receive the corresponding electrical signal transmitted by control module 400, thus de-energizing relay 211. When relay 211 is de-energized, cylinder 221 releases gas and contracts, referring to... Figure 6 As shown, cylinder 221 drives bending lock 222 to lift, bending lock 222 will release the first connecting end 101a, ensuring that the first connecting end 101a and the second connecting end 301a are separated, and the feeding trolley 100 and the shredder body 301 are separated.

[0058] Optionally, refer to Figures 1 to 6 As shown, the bending lock 222 includes a T-shaped lock.

[0059] Among them, the bent lock 222 has a variety of different shapes, see reference. Figures 1 to 6 As shown, the bending latch 222 includes a T-shaped latch, which is adjusted to two different states—absorbing gas and releasing gas—by a cylinder 221. Combined with... Figure 5 and Figure 6 As shown, the cylinder 221 can be in two states, bulging and contracting in the horizontal direction, thereby driving the T-shaped latch to fall and lift, thus locking and releasing the first connecting end 101a.

[0060] Figure 7 This is a structural schematic diagram of an I-shaped latch improved according to an embodiment of this utility model, for reference. Figure 7 As shown, the bending lock 222 includes an I-shaped lock.

[0061] Further reference Figure 7 As shown, the bending latch 222 includes an I-shaped latch, which is adjusted to two different states—absorbing gas and releasing gas—by a cylinder 221. (Reference) Figure 7 As shown, cylinder 221 can bulge and retract along the numerical direction, thereby causing the I-shaped latch to fall and rise, thus locking and releasing the first connecting end 101a. This demonstrates the versatility of the bent latch 222's design.

[0062] Optionally, the connection control unit 210 also includes a solenoid valve and a pressure regulating filter.

[0063] Furthermore, the connection control unit 210 can also ensure the solenoid valve and pressure regulating filter. The setting of the solenoid valve and pressure regulating filter can further improve the control accuracy of the connection control unit 210 on the locking unit 220, thereby improving the working stability and reliability of the protection device 10.

[0064] refer to Figure 3 and Figure 6 As shown, the feeding trolley 100 includes a material input trough 110 and a transport connecting chain 120. The transport connecting chain 120 is connected to the input pipe 303 of the shredder body 301. The material is transferred to the feeding trolley 100 through the material input trough 110, and the feeding trolley 100 transfers the material to the shredder body 301 through the transport connecting chain 120.

[0065] Further reference Figure 3 and Figure 6 As shown, the feeding trolley 100 includes a material input trough 110, through which materials are input into the feeding trolley 100 for transport. The feeding trolley 100 also includes a transport connecting chain 120. When the feeding trolley 100 is mechanically connected to the shredder body 301 (the first connecting end 101a and the second connecting end 301a are mechanically connected), the transport connecting chain 120 can be aligned to ensure connection with the input pipe 303 of the shredder body 301, thereby transferring the material placed in the material input trough 110 to the shredder body 301 for further processing. Optionally, the material can be tobacco shreds, etc.
