[0021] Figure 3 This is a schematic structural diagram of the interlocking device provided in an embodiment of the present application after removing the positioning plate. DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a protective door interlock device of a residual cigarette processing machine, which is applied to the protective door of the residual cigarette processing machine in a cigarette factory, and specifically plays a linkage effect. When the protective door is opened, the residual cigarette processing machine can be automatically shut down. In the process of the residual cigarette processing machine processing defective cigarettes, when the residual cigarette processing machine needs to be repaired or other operations, the protective door must be opened to carry out internal maintenance. In order to improve the safety of the operation process, the residual cigarette processing machine must be shut down when the protective door is opened. The current method is to set an interlock device on the protective door. The interlock device includes a mechanical limit switch. The mechanical limit switch and the electrical control cabinet of the residual cigarette processing machine are linked and connected. The sensing contact of the mechanical limit switch is set on the residual cigarette processing machine. When the protective door of the residual cigarette processing machine is closed, the protective door can contact the sensing contact of the mechanical limit switch and press the sensing contact The head enables the residual smoke treatment machine to operate normally. When the protective door is in the open state, the protective door no longer presses the sensing contact, so that the sensing contact is released, and the residual smoke treatment machine is shut down, achieving the effect of linkage control and improving safety. However, in practice, due to the large amount of dust in the workshop, dust is easily accumulated at the mechanical limit switch. The presence of dust increases the friction of the sensing contact and even causes the sensing contact to get stuck. When the protective door is opened, the sensing contact cannot be released smoothly, resulting in the residual smoke treatment machine being unable to shut down, posing a certain safety hazard. The protective door interlocking device for the residual smoke treatment machine provided in this application is intended to ensure that the residual smoke treatment machine can shut down normally when the protective door is opened, and can ensure that the residual smoke treatment machine can shut down even in a dusty environment, thereby improving the safety of opening the protective door to inspect and repair the residual smoke treatment machine.

[0024] The protective door interlock device of the residual smoke treatment machine includes a first mounting part, a second mounting part and a magnetic sensing switch. The magnetic sensing switch includes a sensing end 100 and a magnetic end 200. The second mounting part has a first state and a second state relative to the first mounting part. The sensing end 100 is arranged on the first mounting part, and the magnetic end 200 is arranged on the second mounting part. When the second mounting part is in the first state relative to the first mounting part, the magnetic end 200 is close to the sensing end 100 and can trigger the sensing end 100. When the second mounting part is in the second state relative to the first mounting part, the magnetic end 200 is away from the sensing end 100, and the magnetic end 200 cannot trigger the sensing end 100. In an example, the first mounting part is the residual smoke treatment machine, and the second mounting part is the protective door on the residual smoke treatment machine. The first state refers to the protective door being in the closed state, and the second state refers to the protective door being in the open state. The magnetic sensing switch The closed sensing end 100 is electrically connected to the electrical control cabinet of the residual smoke treatment machine through an electrical connecting line. When the magnetic end 200 approaches the sensing end 100, the sensing end 100 is triggered. At this time, the residual smoke treatment machine operates normally. When the magnetic end 200 is away from the sensing end 100 and no longer triggers the sensing end 100, the residual smoke treatment machine stops. The sensing end 100 is set on the residual smoke treatment machine, and the magnetic end 200 is set on the protective door of the residual smoke treatment machine. Moreover, when the protective door is in the closed state, the positions of the sensing end 100 and the magnetic end 200 correspond, so that the magnetic end 200 can trigger the sensing end 100, and the residual smoke treatment machine remains in operation. When the residual smoke treatment machine needs to be repaired or the protective door needs to be opened, the protective door is opened. At this time, the magnetic end 200 is away from the sensing end 100, the sensing end 100 is no longer triggered, and the residual smoke treatment machine stops, ensuring safety when opening the protective door for maintenance.

[0025] Compared with mechanical limit switches, magnetic induction switches are not affected by dust and respond more sensitively and accurately to the opening and closing status of the protective door, ensuring that the residual smoke treatment machine can be shut down when the protective door is opened, ensuring the safety of operation.

[0026] Preferably, the sensing end 100 includes a first mounting plate 101, which is in the shape of a long plate. A sensing element 102 is provided on one side of the first mounting plate 101. The sensing element 102 is used to connect to the electrical control cabinet of the residual smoke treatment machine. A first electrical terminal and a second electrical terminal are provided on the sensing element 102. The sensing element 102 is connected to the electrical control cabinet of the residual smoke treatment machine through the first electrical terminal and the second electrical terminal. In this embodiment, the sensing element 102 is provided in the shape of a rectangular parallelepiped, and the first electrical terminal and the second electrical terminal are located on the same side of the sensing element 102. To facilitate circuit connection, when the magnetic end 200 approaches the sensing end 100 to trigger the sensing end 100, the side of the sensing element 102 opposite to the same side faces the magnetic end 200. That is, the plane where the first mounting plate 101 is located is a vertical plane, one side of the sensing element 102 is connected to one side of the first mounting plate 101, the top side of the sensing element 102 faces upward, and the bottom side of the sensing element 102 faces downward. The first electrical terminal and the second electrical terminal are arranged on the top side of the sensing element 102. When the magnetic end 200 triggers the sensing end 100, the bottom side of the sensing element 102 faces the magnetic end 200.

[0027] Positioning holes may be provided on the first mounting plate 101 so as to be connected to the first mounting portion by bolts.

[0028] In this embodiment, the first electrical terminal includes a first screw 301, and the second electrical terminal includes a second screw 302. A threaded hole for installing the first screw 301 and the second screw 302 is provided on the sensing element 102. Two threaded holes are provided on the sensing element 102, respectively for installing the first screw 301 and the second screw 302, so as to perform a crimping connection with the electrical connection wire. The connection of the electrical connection wire is achieved by means of the first screw 301 and the second screw 302, which is convenient to operate and has a tight connection.

[0029] More preferably, a first dividing bar 401 is provided on the sensing element 102, and the first dividing bar 401 is located on the side where the threaded hole is provided. The first dividing bar 401 protrudes from the outer surface of the sensing element 102, and the two threaded holes are respectively located on both sides of the first dividing bar 401. After the electrical connection line is connected, the first screw 301 and the second screw 302 are respectively located on both sides of the first dividing bar 401, which is convenient for classifying and marking the lines. Moreover, due to the protrusion of the first dividing bar 401, when the sensing end 100 is installed, it can provide a protruding protection effect for the first screw 301, the second screw 302 and the electrical connection line, thereby preventing external equipment from seriously touching the first screw 301, the second screw 302 and the connector of the electrical connection line.

[0030] In this embodiment, a second dividing bar 402 is provided on the first mounting plate 101 or the sensing element 102, and the first dividing bar 401 is connected to the middle part of the second dividing bar 402. Preferably, the first dividing bar 401 is vertically connected to the middle part of the second dividing bar 402 to form a T-shape. The second dividing bar 402 also protrudes from the outer surface of the sensing element 102, and the protruding height of the second dividing bar 402 is the same as the protruding height of the first dividing bar 401. The first dividing bar 401 and the second dividing bar 402 both have a certain length, and the two form a T-shape, dividing two spaces for the installation of the first screw 301 and the second screw 302 respectively, thereby realizing the connection and installation of the electrical connection line. In this way, the installation space formed by the first dividing bar 401 and the second dividing bar 402 has a more obvious protective effect on the first screw 301, the second screw 302 and the electrical connection line joint, forming a similar concave installation space, thereby improving the safety of the equipment.

[0031] More preferably, the second dividing bar 402 is arranged on the first mounting plate 101, the first dividing bar 401 is arranged on the sensing element 102, and the first dividing bar 401 is vertically connected to the second dividing bar 402, so that the first dividing bar 401 and the second dividing bar 402 also act as reinforcing ribs, thereby improving the connection strength between the sensing element 102 and the first mounting plate 101.

[0032] In some embodiments, the magnetic end 200 includes a second mounting plate 201, which is in the shape of a long plate. A magnetic member 202 is provided on one side of the second mounting plate 201, and the magnetic member 202 is a permanent magnet. Preferably, the second mounting plate 201 and the first mounting plate 101 have the same shape, and the shape of the magnetic member 202 is the same as the shape of the sensing element 102. The magnetic member 202 is in the shape of a rectangular parallelepiped. When the plane where the second mounting plate 201 is located is a vertical plane, one side of the magnetic member 202 is connected to one side of the second mounting plate 201, the top side of the magnetic member 202 faces upward, and the bottom side of the magnetic member 202 faces downward. When the magnetic end 200 approaches the sensing end 100 and triggers the sensing end 100, the top side of the magnetic member 202 faces the bottom side of the sensing element 102. Taking a horizontal plane, the bottom side of the sensing element 102 and the top side of the magnetic member 202 are parallel to the horizontal plane. The second mounting portion is preferably hinged to the first mounting portion. When the second mounting portion is relative to the first mounting portion When switching between the first state and the second state, the sensing element 102 does not pass through the moving path of the magnetic member 202, that is, the second mounting portion drives the magnetic member 202 to swing in the horizontal direction. In the first state, the magnetic member 202 swings to directly below the sensing element 102, so that the magnetic member 202 triggers the sensing element 102. Then, when the second mounting portion changes from the first state to the second state, the second mounting portion drives the magnetic member 202 to swing. The magnetic member 202 swings horizontally directly below the sensing element 102 and gradually moves away from the sensing element 102. In the second state, the magnetic member 202 no longer triggers the sensing element 102. In this way, contact and interference between the magnetic member 202 and the sensing element 102 can be avoided. Moreover, when the first mounting portion is a residual smoke treatment machine and the second mounting portion is a protective door, the magnetic attraction between the magnetic member 202 and the sensing element 102 is perpendicular to the swinging direction of the protective door, and no excessive resistance is generated to the opening of the protective door.

[0033] In some embodiments, a T-shaped rib may be provided on the same side of the second mounting plate 201 and the magnetic member 202 to make the appearance of the sensing end 100 more consistent and aesthetically pleasing.

[0034] More preferably, a positioning plate 500 is provided on the second mounting portion, and the magnetic end 200 is provided on the positioning plate 500. The magnetic end 200 is installed on the second mounting portion through the positioning plate 500. One end of the positioning plate 500 is connected to the second mounting portion, and the magnetic end 200 is adjustably provided at the other end of the positioning plate 500, so that the position of the magnetic end 200 can be adjusted, thereby adjusting the distance between the magnetic end 200 and the sensing end 100 when the magnetic end 200 approaches the sensing end 100 and triggers the sensing end 100. In this embodiment, the bottom end of the positioning plate 500 is connected to the second mounting portion. Then, the top of the positioning plate 500 is used to install the magnetic end 200. A vertically extending waist-shaped groove 501 is set on the top of the positioning plate 500. A mounting hole is set on the second mounting plate 201. The second mounting plate 201 is connected to the waist-shaped groove 501 by bolts, so that the vertical position of the second mounting plate 201 can be adjusted. When the magnetic part 202 swings to the bottom of the sensing element 102, the vertical distance between the magnetic part 202 and the sensing element 102 can be adjusted. When the equipment is running for a long time and the gap between the components changes, it can be adjusted to ensure the triggering sensitivity of the sensing element 102.
