DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] As Figures 1-4 shown, it relates to a kind of conveying devices for spraying assembly line, including top frame plate 1, the middle part of top frame plate 1 is hollow design, four corners of top frame plate 1 close to hollow position are all connected with vertical shaft 2 by bearing rotation, the bottom end of each vertical shaft 2 is fixed with chain gear 3, the surface of multiple chain gears 3 is jointly meshed and connected with chain 4, chain 4 lower surface is equidistant and fixed with several suspension assemblies 5, and the side of top frame plate 1 lower surface is fixed with side plate 6, and side plate 6 is fixed with friction strip 7 close to the side of chain 4, and the four corners of top frame plate 1 lower surface and located chain 4 outside are fixed with support assembly 9.

[0024] The upper surface of top frame plate 1 is fixed with motor 8 away from the side of side plate 6, and the output end of motor 8 is fixedly connected with any vertical shaft 2.

[0025] In the embodiment, motor 8 adopts speed reducer, drives one of vertical shaft 2 to rotate after driving one of vertical shaft 2 by motor 8, to drive corresponding chain gear 3 to rotate, so as to drive chain 4 to move using the chain gear 3, and the suspension assembly 5 at the bottom of chain 4 will move synchronously with chain 4.

[0026] The use of the embodiment is aimed at small and light parts suspension spraying, to avoid chain 4 and chain gear 3 separation caused by too heavy parts;When the relatively heavy parts are hung, a guide rail can be installed on the lower surface of top frame plate 1, and chain 4 is guided and supported using the guide rail.

[0027] The suspension assembly 5 includes a vertical rod 51 fixed to the lower surface of the chain 4. A sleeve 52 is rotatably connected to the bottom surface of the vertical rod 51 via a bearing. A disc 53 is fixed to the lower surface of the sleeve 52. The side of the disc 53 near the side plate 6 is in close contact with the surface of the friction strip 7. A hook 54 is fixed to the lower surface of the disc 53.

[0028] In this embodiment, when suspending parts, the parts can be directly hung on the hook 54. Since the sleeve 52 is rotatably connected to the bottom end of the vertical rod 51, when the disc 53 is in contact with the friction strip 7, as the suspension assembly 5 moves with the chain 4, the disc 53 will also rotate along the surface of the friction strip 7 under the action of friction, causing the hook 54 to rotate as well, thereby causing the parts hanging on the hook 54 to rotate, ensuring that the coating is comprehensive.

[0029] The top frame plate 1 is located in the spraying equipment of the spraying production line on the side of the side plate 6, and the motor 8 is located outside the spraying equipment.

[0030] The suspension assembly 5 will rotate after moving into the spraying equipment along with the chain 4, thereby causing the parts to rotate.

[0031] A detachable rubber ring is fixedly fitted to the outer wall of the disc 53.

[0032] In this embodiment, the surface of the disc 53 is provided with an annular groove, and the rubber ring is stuck inside the annular groove, so the rubber ring can be directly removed. The friction strip 7 is also made of rubber, and the rubber ring on the surface of the disc 53 can contact the friction strip 7 more tightly and with greater friction, which is beneficial to the rotation of the disc 53. When the friction between the rubber ring and the friction strip 7 decreases due to wear, the rubber ring on the surface of the disc 53 can be removed and replaced from outside the spraying equipment.

[0033] The support assembly 9 includes a support rod 91 fixed to the lower surface of the top frame plate 1. A square tube 92 is slidably connected to the bottom surface of the support rod 91. A base plate 93 is fixedly connected to the bottom end of the square tube 92. A through hole 94 is opened at the top end of the square tube 92, and an insertion rod 95 is slidably connected inside the through hole 94. An insertion hole 96 is opened at the bottom end of the support rod 91, and one end of the insertion rod 95 located inside the square tube 92 is inserted into the insertion hole 96.

[0034] When the support rod 91 extends fully from inside the square tube 92, the insertion rod 95 is inserted into the insertion hole 96, using the insertion rod 95 to support and fix the support rod 91. When it is necessary to inspect or replace the rubber ring on the surface of the disc 53, the insertion rods 95 of the multiple support components 9 are pulled out from the insertion holes 96 at the bottom of the support rod 91. During this process, technicians use other lifting devices to lift and support the top frame plate 1, and then move the support rod 91 downwards, causing the top frame plate 1 to drop, thereby facilitating inspection and maintenance.

[0035] An end plate 97 is fixed to one end of the insertion rod 95 outside the square tube 92, and a tension spring 98 is fixedly connected to the end plate 97 and the outer wall of the square tube 92. A pull ring is fixed to the other side of the end plate 97.

[0036] By setting a pull ring, the end plate 97 can be pulled to separate the insertion rod 95 from the insertion hole 96. After the maintenance is completed, the support rod 91 is moved upward. After the insertion hole 96 and the insertion rod 95 are aligned, the tension spring 98 pulls the end plate 97 to reset, so that the insertion rod 95 is re-inserted into the insertion hole 96.

[0037] Working principle: First, hang the parts on the hooks 54 on the outside of the spraying equipment. Start the motor 8 to drive the chain 4 to rotate, so that the hooks 54 located outside the spraying equipment move into the spraying equipment. When the disc 53 of the suspension component 5 contacts the friction strip 7, the disc 53 and the parts will also rotate, thus ensuring full spraying. After spraying, the parts are moved out from the other side of the equipment with the chain 4. At this time, the worker can take the parts off the hooks 54 and re-hang the parts to be sprayed.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
