Description

Technical Field

[0001] The invention relates to the technical field of PLC electrical engineering automation, and in particular to a rotating bracket of PLC electrical engineering automation. Background Art

[0002] As the global manufacturing industry moves towards intelligent and efficient transformation, the degree of industrial automation continues to deepen and expand. In various production scenarios, from traditional machinery manufacturing and chemical production to emerging electronic equipment assembly and new energy product processing, production line processes are becoming increasingly complex and sophisticated. PLC programmable logic controllers, as core control units, are widely used in automation systems, responsible for implementing logical judgment, data processing and command issuance for production equipment and process links. Electronic control technology has made a leap forward, and miniaturized motor drives and intelligent sensor integration have given the bracket automatic rotation, angle feedback, and adaptive adjustment capabilities. Combined with PLC programming control, it can be flexibly driven to rotate according to preset logic or real-time working conditions, meeting the needs of coordinated operation of electrical engineering automation systems in multiple dimensions.

[0003] In some production workshops involving oil products, such as fried food production, oil and fat chemical industries, the products themselves contain a lot of oil. During the automated packaging and transportation process, the oil on the surface of the product may rub onto the equipment. For example, in an edible oil filling workshop, a small amount of oil may overflow from the filling equipment during the filling process, flowing along the filling pipe, or on the product conveyor belt. The grease on the outside of the bottle will be contaminated onto the conveyor belt and the surrounding PLC control equipment. These oil stains will gradually spread to the surface of other automated devices as the product flows and the equipment operates. This patent is to provide a rotating bracket for PLC electrical engineering automation to alleviate the technical problem in the prior art that oil stains accumulate in the heat dissipation area of ​​the PLC electrical engineering automation equipment, which easily leads to heat accumulation in the internal components of the PLC electrical engineering automation and damages the life of the electronic components. Summary of the invention

[0027] In one embodiment, for the above-mentioned sliding soft block 25, the sliding soft block 25 is slidably connected to the support frame 2, a groove for cleaning the side of the rotating rod 4 is provided on the side of the sliding soft block 25, the rotating rod 4 is fixedly connected to the column 24, the threaded rod 23 is threadedly connected to the sliding soft block 25, and a heat dissipation window 10 is provided on the side of the PLC device host 9.

[0028] In this embodiment, the sliding soft block 25 is arranged to move outside the threaded rod 23 to ensure intermittent cleaning of oil stains when the left and right detection of the PLC device host is performed. When the sliding soft block gradually squeezes the rotating rod 4 along the screw rod, it has the flexibility to clean it for a circle, and then rotates in the opposite direction again to gradually move away from the rotating rod 4.

[0029] In one embodiment, for the above-mentioned support column 20, the support column 20 is transmission-connected with a second transmission belt 19, the second transmission belt 19 is transmission-connected with a second connecting rod 18, a second bevel gear 17 is arranged above the second connecting rod 18, and the second connecting rod 18 is rotationally connected to the support frame 2.

[0030] In one embodiment, for the fourth bevel gear 22 , a column 24 is disposed on the side of the fourth bevel gear 22 , and the column 24 is fixed above the support frame 2 .

[0031] In this embodiment, the pillars 24 disposed on the side of the fourth bevel gear 22 can provide good support to ensure the stability of the entire device.

[0032] In one embodiment, for the above-mentioned rotating rod 4, the rotating rod 4 is transmission-connected with a first transmission belt 5, the first transmission belt 5 is transmission-connected with a support rod 6, the support rod 6 is rotationally connected with a connecting block 7, the connecting block 7 is fixed on one side of the support frame 2, and a support frame 2 is arranged above the base 1.

[0033] In this embodiment, the transmission belt provided on the rotating rod 4 can facilitate cleaning of the oil stains when the rotating rod 9 rotates.

[0034] In one embodiment, for the above-mentioned sliding rack plate 11, one side of the sliding rack plate 11 is provided with an adsorption felt for absorbing oil stains on the surface of the PLC device host 9, and one side of the sliding soft block 25 is provided with a soft felt for absorbing oil stains on the surface of the rotating rod 4.

[0035] In this embodiment, an adsorption felt is provided on one side of the sliding rack plate 11 to facilitate the adsorption of oil stains during up and down cleaning.

[0036] In one embodiment, for the long column 12 , the long column 12 is fixedly connected to the support frame 2 , and a protective box 8 is fixedly connected above the support frame 2 .

[0037] The working principle of a rotating bracket for PLC electrical engineering automation in the present invention is that when 1 is fixed in a suitable workshop for automated inspection, under normal circumstances, the oil stains need to be cleaned after a period of time, and then the PLC equipment host 9 controls the motor 3 to rotate, and then drives the rotating rod 4 to rotate. The rotating rod 4 will drive the third bevel gear 21 to engage with the fourth bevel gear 22 through the second transmission belt 19, and then the fourth bevel gear 22 rotates to make the sliding soft block 25 move on the surface of the threaded rod 23. When the sliding soft block 25 gradually rotates along the threaded rod 23, when it is finally squeezed to the maximum extent, it can just wipe off the oil stains around the surface of the rotating rod 4.

[0038] At the same time, the rotation of the rotating rod 4 drives the second bevel gear 17 to rotate, and the second bevel gear 17 is meshed with the first bevel gear 16. The first bevel gear 16 drives the rotating gear 13 to rotate, and the rotating gear 13 causes the sliding rack plate 11 to move up and down to clean the side of the PLC device host 9. When the rotating rod 4 is squeezed to the maximum extent, the sliding rack plate 11 has just cleaned the side of the PLC device host 9, and will reset to return the PLC device host 9 to its original position. Then, under normal circumstances, the PLC device host 9 will rotate left and right to monitor the fried products, so it will not be cleaned. By setting the program inside the PLC device, cleaning is performed at intervals. At the same time, the sliding soft block 25 and the sliding rack plate 11 need to be replaced at intervals to prevent the expected oil cleaning effect from failing.

[0039] In this embodiment, the long column 14 disposed above the support frame 2 can increase its stability during cleaning.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
