DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0028] In one embodiment of the present invention, see Figure 1 The coating machine safety protection mechanism comprises a base 1, on which side panels 2 are symmetrically arranged, and a conveying roller 4 and a coating roller 5 that cooperate with each other are rotatably connected between the symmetrically arranged side panels 2, one end of the conveying roller 4 is connected to a motor 3, and the other end of the conveying roller 4 is connected to a gear 6, and one end of the coating roller 5 is connected to a gear 2 7 that meshes with the gear 1 6, and a connecting seat 9 is slidably provided on the side where the side panels 2 are close to each other, and a plurality of railings 10 are connected between the symmetrically arranged connecting seats 9, and a limiting assembly is provided between the side panels 2 and the connecting seats 9, and an infrared grating alarm 11 is installed on the side wall of the side panel 2 between the railing 10 and the conveying roller 4.

[0029] In this embodiment, the coating machine can be effectively protected by a plurality of railings 10 to prevent the hands of outsiders from accidentally entering between the conveying roller 4 and the coating roller 5, thereby improving the safety of the device. The infrared grating alarm 11 can detect the accidental entry of the hands of outsiders and issue a warning in time, thereby avoiding safety accidents. The limiting assembly can stably limit the connecting seats 9 at different heights to improve the protection range of the device, and has the effects of safety protection, timely warning, stable limiting, rapid disassembly and assembly, wide protection range, reliable structure and simple and practical use. Among them, a connecting groove 19 is provided on the side where the side panels 2 are close to each other, and a slide groove 12 is provided on one side of the connecting groove 19. A slide bar 13 connected to the connecting seat 9 is slidably provided in the slide groove 12. Through the sliding cooperation of the slide groove 12 and the slide bar 13, it is convenient to stably guide the lifting and lowering of the connecting seat 9. The slide groove 12 is set as a dovetail groove, and a plurality of railings 10 are distributed in an S shape from top to bottom.

[0030] In one embodiment of the present invention, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting assembly includes a tooth groove 14 arranged on one side of the connecting seat 9, a limiting tooth plate 15 movably provided in the connecting groove 19 and movably engaged with the tooth groove 14, a pulling plate 8 movably provided on the outer side of the side plate 2, a sliding rod 18 passing through the side plate 2 is connected between the pulling plate 8 and the limiting tooth plate 15, and a spring 17 sleeved on the outer side of the sliding rod 18 is connected between the limiting tooth plate 15 and the side plate 2.

[0031] In this embodiment, in the initial state, the limit tooth plate 15 cooperates with the tooth groove 14, the spring 17 is at its original length, and the pull plate 8 is close to the side plate 2. At this time, the height of the connecting seat 9 is fixed. When the height of the connecting seat 9 needs to be adjusted or the connecting seat 9 needs to be removed, the pull plate 8 is pulled outward, and the pull plate 8 drives the limit tooth plate 15 to move synchronously through the slide bar 18. The limit tooth plate 15 releases the limit of the connecting seat 9 by moving away from the tooth groove 14, which is convenient for adjusting the height of the connecting seat 9 or removing the connecting seat 9, and is convenient for removing, cleaning and replacing the connecting seat 9 and the railing 10. After the height of the connecting seat 9 is adjusted or removed After taking it out, release the pull plate 8, the spring 17 extends and pushes the limiting tooth plate 15 away from the side plate 2, and the limiting tooth plate 15 is positioned at the height of the connecting seat 9 by meshing with the tooth groove 14 and sliding cooperation between the slide groove 12 and the slide bar 13, thereby meeting the protection requirements of the device at different heights and improving the applicability of the device. Among them, the connecting groove 19 is symmetrically provided with a guide rod 16 about the slide rod 18, and the guide rod 16 is slidingly cooperated with the limiting tooth plate 15. Through the sliding cooperation between the guide rod 16 and the limiting tooth plate 15, the movement of the limiting tooth plate 15 can be stably supported, thereby improving the limiting effect of the connecting seat 9.
