[0031] Example

[0032] like Figure 1 As shown, the present invention proposes a protective shield for a food production line, comprising a plurality of shield bodies, including a top plate 1, with four sets of support rods 2 fixedly connected to the bottom of the top plate 1. A door frame 3 is disposed between two sets of support rods 2 on the same side of the production line. The door frame 3 is hinged to the sides of the support rods 2 and is equipped with a handle for easy opening and closing and a lock for easy locking. A light-transmitting door panel 4 is mounted within the door frame 3. The light-transmitting door panel 4 is made of a transparent acrylic sheet, which is easy to observe, has a long service life, and is not easily aged.

[0033] For further information, see Figure 2-5, the above-mentioned protective cover further includes a connection mechanism 5 installed at the bottom of the top plate 1. The connection mechanism 5 is connected in series with the pipeline power line. The connection mechanism 5 includes two groups of fixing blocks 501 fixedly connected to the bottom of the top plate 1. The fixing blocks 501 are arranged in a "U" shape and the positions of the fixing blocks 501 are fixed. Connecting wires 502 are connected to the mutually remote sides of the two groups of fixing blocks 501. The connecting wires 502 are connected in series with the power line. The electrode plates 505 are energized through the connecting wires 502, so that a circuit is formed after the two electrode plates 505 contact the conductive blocks 506 and the pipeline operates normally, and the pipeline stops operating after the circuit is broken. Two moving plates 503 are respectively slidably connected in the two groups of fixing blocks 501. Two conductive rods 504 are slidably connected in the moving plates 503. The ends of the two conductive rods 504 remote from the fixing blocks 501 are fixedly connected together with an electrode plate 505. A conductive block 506 is arranged between the two electrode plates 505. A first spring 507 is sleeved outside the conductive rod 504. The first spring 507 is arranged between the moving plate 503 and the electrode plate 505. The first spring 507 is used to release elastic force to make the electrode plate 505 press against the conductive block 506 to ensure good contact. The ends of multiple conductive rods 504 remote from the electrode plate 505 are fixedly connected together with a limiting plate 508. The limiting plate 508 is used for limiting. Multiple fixing cylinders 509 are installed in the fixing blocks 501. A sliding rod 510 is slidably connected in the fixing cylinders 509. The end of the sliding rod 510 remote from the fixing cylinder 509 is fixedly connected to the moving plate 503. A second spring 511 is also sleeved outside the sliding rod 510. The second spring 511 is arranged between the fixing cylinder 509 and the moving plate 503. The second spring 511 is used to release elastic force to drive the pulley 62 to closely adhere to the outside of the partition plate 63.

[0034] Furthermore, the above protective cover includes a cutting component 6 disposed in the connecting mechanism 5. The cutting component 6 is used to cut off the circuit formed by the connecting mechanism 5 after moving. The cutting component 6 includes multiple sets of mounting frames 61 fixedly connected to the side of the moving plate 503 away from the fixed cylinder 509. The mounting frames 61 are arranged in a "U" shape. A pulley 62 is rotatably connected in the mounting frame 61. When the pulley 62 rotates, it reduces the friction force, facilitating the movement of the two sets of partition plates 63. Two sets of partition plates 63 are also arranged between the two fixed blocks 501. The pulley 62 is in contact with the partition plate 63. Grooves 64 are formed on both sides of the partition plate 63. Due to the action of the second spring 511 when the partition plate 63 moves, the pulley 62 can always closely adhere to the outer side of the partition plate 63. The two sets of partition plates 63 are respectively fixedly connected above and below the conductive block 506. When the partition plate 63 moves, it drives the conductive block 506 to move synchronously. And two sets of insulating blocks 65 are fixedly connected between the two sets of partition plates 63, which are used to fix the two sets of partition plates 63 and at the same time facilitate the separation of the two electrode plates 505. The two sets of insulating blocks 65 are respectively located on both sides of the conductive block 506. Two sets of limiting blocks 66 are also installed at the bottom of the top plate 1. The upper set of partition plates 63 is slidably connected between the two sets of limiting blocks 66, which is used to limit the movement of the partition plate 63. A synchronous plate 67 is fixedly connected to the side of the two sets of partition plates 63 close to the door frame 3. When the synchronous plate 67 moves, it drives the two sets of partition plates 63 to move synchronously.

[0035] Finally, the above protective cover further includes a linkage component ۷ installed on one side of the cutting component 6. The linkage component ۷ is used to drive the cutting component 6 to move after the door frame 3 is opened. The linkage component ۷ includes multiple sets of connecting rods ۷۱ fixedly connected to the side of the synchronous plate 67 away from the partition plate 63. The ends of the multiple sets of connecting rods ۷۱ away from the synchronous plate 67 are jointly fixedly connected with a mounting piece ۷۲. The mounting piece ۷۲ drives the synchronous plate 67 to move synchronously through the connecting rods ۷۱. A rubber pad ۷۳ is installed on the side of the mounting piece ۷۲ away from the connecting rod ۷۱. The rubber pad ۷۳ plays a buffering role. A fixing plate ۷۴ is slidably connected to the multiple sets of connecting rods ۷۱. The fixing plate ۷۴ is fixedly connected to the bottom of the top plate 1. The position of the fixing plate ۷۴ is fixed, making the movement of the connecting rods ۷۱ stable. Multiple sets of third springs ۷۵ are arranged between the fixing plate ۷۴ and the mounting piece ۷۲. The multiple sets of third springs ۷۵ are respectively sleeved on the outer circles of the multiple sets of connecting rods ۷۱. The third springs ۷۵ are used to release elastic force after the door frame 3 is opened, drive the mounting piece ۷۲ to move, and thus drive the conductive block 506 to leave between the two electrode plates 505.

[0036] In this embodiment, the door frame 3 and the light-transmitting door panel 4 provide protection, and the working status of the assembly line can be observed through the light-transmitting door panel 4, ensuring food safety and hygiene. When performing maintenance, the assembly line is first powered off, and then the door frame 3 is opened. After the door frame 3 is opened, the third spring 75 releases its elastic force, driving the mounting plate 72 away from the fixed plate 74. At this time, the mounting plate 72 drives the synchronization plate 67 to move synchronously via the connecting rod 71. The synchronization plate 67 now drives the two sets of partition plates 63 to move, and the partition plates 63 move smoothly under the restraining action of the two sets of limit blocks 66. At this time, under the action of the second spring 511, the pulley 62 is tightly attached to the outside of the partition plate 63. When the partition plate 63 moves, the pulley 62 moves out of the groove 64, simultaneously driving the electrode plate 505 away from the conductive block 506, thus disconnecting the circuit. The two sets of electrode plates 505 located on either side of the insulating block 65 also prevent accidental energization. Therefore, even if the assembly line is started by mistake, the assembly line will not start because the electrode sheet 505 is disconnected from the conductive block 506, thereby ensuring the safety of the operator.

[0037] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
