Description

Technical Field

[0001] The utility model relates to the technical field of equipment lubrication, in particular to an automatic lubrication device for parts used in a coating production line. Background Art

[0002] The coating line is a long-term double-shift production line, and the equipment maintenance time is relatively short. Since the drying room in the production line is located in the first section after the pre-treatment water washing, the trolleys on the production line will have some water after the pre-treatment water washing. When the trolleys enter the drying room, water droplets are easy to slide onto the production line chain in the drying room. Under long-term working conditions, the lubricating oil on the chain is easily washed away by water, causing chain corrosion. Therefore, the staff is required to regularly lubricate the chain in the drying room.

[0003] However, during the production process, the drying room temperature of the coating production line is higher than 90°. Production needs to be stopped before lubricating the chain in the drying room. After the temperature of the equipment in the drying room drops, the staff can manually lubricate the chain. The coating production line cannot be put into production during the cooling period, which makes the manual lubrication method reduce production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses an automatic lubrication device for components used in a coating production line, referring to Figure 1 , Figure 2 and Figure 3 , including an oil storage tank 1, which is mounted on the outer wall of the drying room through a mounting frame. An oil outlet pipe 2 is welded at the bottom of the oil storage tank 1, and the outlet of the oil outlet pipe 2 extends into the drying room and is located directly above the chain 20. The bottom of the oil storage tank 1 is higher than the outlet of the oil outlet pipe 2 in the vertical direction, and a control valve 3 for intermittently opening / closing its own pipeline is installed on the oil outlet pipe 2. A protective cover 4 for the chain 20 to pass through is welded on the outer wall of the outlet of the oil outlet pipe 2, and first through holes 41 are opened on both side walls of the protective cover 4 along the length direction of the chain 20, and a transportation channel is formed between the two first through holes 41 on the protective cover 4. A cleaning component 5 for drying and cleaning water stains on the chain 20 is installed on the side wall of the protective cover 4 at the inlet end of the transportation channel. An opening is opened at the bottom of the protective cover 4, and a recovery box 6 is arranged below the opening of the protective cover 4, and an oil drain pipe 7 is welded on one side of the recovery box 6, and the oil drain pipe 7 extends out of the drying room and is externally connected to a processing mechanism 8.

[0020] The control valve 3 is connected to a controller, which can be a PLC integrated circuit system or a computer control system. The controller controls the control valve 3 to open the oil outlet pipe 2 at intervals, and discharges lubricating oil to lubricate the chain 20 within a set time. The interval time and the set oil outlet time can be programmed and set by the staff in the controller.

[0021] In the embodiment of the present application, the chain 20 passes through the transport channel of the protective cover 4 and is always in a transmission state. The control valve 3 opens the oil outlet pipe 2 at regular intervals to add oil and lubricate the chain 20 below. Since the chain 20 is in a transmission state, each section of the chain 20 can be moved to the bottom of the oil outlet of the oil outlet pipe 2 for oiling and lubrication. The protective cover 4 is welded on the outer wall of the outlet of the oil outlet pipe 2 to prevent the lubricating oil from splashing when it is added to the chain 20 and contaminating other components in the drying room. A cleaning component 5 for drying and cleaning water stains on the chain 20 is installed at the entrance end of the transport channel on the protective cover 4. The cleaning component 5 can dry the water stains on the chain 20 entering the protective cover 4, thereby improving the adhesion effect of the lubricating oil discharged from the oil outlet pipe 2 on the chain 20. Compared with the traditional lubrication method, the automatic lubrication device of the present application can automatically add oil and lubricate the chain 20 during the operation of the coating production line, without stopping production and waiting for the temperature to drop before the staff enters the drying room to add oil and lubricate, which has the effect of improving production efficiency.

[0022] Specifically, the cleaning component 5 includes a fan 51, and a mounting frame 52 is provided on the side of the protective cover 4 at the entrance end of the transport channel, and a second through hole 521 communicating with the transport channel is horizontally penetrated through the mounting frame 52. The fan 51 is installed on the top of the mounting frame 52, and the air outlet of the fan 51 faces the chain 20 below. This requires the chain 20 to pass through the second through hole 521 in the mounting frame 52 before lubrication. The fan 51 blows air to the chain 20 below, which can speed up the air flow rate on the surface of the chain 20, and cooperate with the high temperature environment in the drying room to quickly dry the water stains on the chain 20, thereby improving the adhesion effect of the lubricating oil in the protective cover 4 on the chain 20.

[0023] Furthermore, an oil scraper plate 9 is welded on the protective cover 4 at the outlet end of the transport channel, and one end of the oil scraper plate 9 away from the protective cover 4 extends upwardly and obliquely to form a guide surface 91 , and one end of the oil scraper plate 9 away from the protective cover 4 contacts the bottom of the chain 20 .

[0024] In the embodiment of the present application, the chain 20 is lubricated through the oil outlet pipe 2 when it moves through the protective cover 4. The lubricating oil attached to the chain 20 is easy to drip onto other components in the drying room after it moves out of the protective cover 4 and cause pollution. The oil droplets at the bottom of the chain 20 can be scraped off by the oil scraper 9, and the oil droplets can flow into the protective cover 4 along the guide surface 91 and fall into the recovery box 6 below from the opening at the bottom of the protective cover 4.

[0025] In order to prevent the oil droplets scraped off by the oil scraper 9 from diffusing on the guide surface 91 and flowing onto the outer wall of the protective cover 4, the guide surface 91 is set to be a concave arc surface, so that a lubricating oil guide groove extending from one end close to the chain 20 to the opposite end is formed on the guide surface 91 of the oil scraper 9. This makes the oil droplets scraped off by the oil scraper 9 gather in the concave part of the arc surface when flowing, thereby preventing the oil droplets from diffusing outwards.

[0026] Reference Figure 4 The discharge end of the oil drain pipe 7 is also equipped with a filter device 10 for filtering impurities in the lubricating oil. The filter device 10 includes a mounting cylinder 101 and a filter screen 102. One end of the mounting cylinder 101 is threadedly connected to the outer wall of the discharge end of the oil drain pipe 7, and the mounting cylinder 101 is located above the feed end of the processing mechanism 8. An annular groove is opened on the inner wall of the mounting cylinder 101 along its circumference, and the filter screen 102 is embedded in the annular groove.

[0027] Since the chain 20 is prone to be attached with some impurities in a long-term working state, the lubricating oil scraped off by the scraper 9 will also be mixed with impurities. After the oil drops fall into the recovery box 6, it can be discharged into the installation cylinder 101 along the oil discharge pipe 7, filtered by the filter screen 102, and then poured into the processing mechanism 8. Since the discharge end of the oil discharge pipe 7 is outside the drying room, the staff can replace the filter device 10 without entering the drying room.

[0028] An observation window 11 for observing the internal lubricating oil level is installed on the side wall of the oil storage tank 1. Since the oil storage tank 1 is located outside the wall of the drying room, the staff can replenish the lubricating oil in the oil storage tank 1 in time according to the liquid level observed through the observation window 11.

[0029] The implementation principle of the automatic lubrication device for components used in a coating production line in the embodiment of the present application is as follows: the control valve 3 opens the oil outlet pipe 2 at regular intervals to add oil and lubricate the chain 20 below. A protective cover 4 is welded on the outer wall of the outlet of the oil outlet pipe 2 to prevent the lubricating oil from splashing when it is added to the chain 20 and contaminating other components in the drying room. A cleaning component 5 for drying and cleaning water stains on the chain 20 is installed on the protective cover 4 at the entrance end of the transportation channel. The cleaning component 5 can dry the water stains on the chain 20 entering the protective cover 4, thereby improving the adhesion effect of the lubricating oil discharged from the oil outlet pipe 2 on the chain 20. Compared with the traditional lubrication method, the automatic lubrication device of the present application can automatically add oil and lubricate the chain 20 during the operation of the coating production line, without stopping production and waiting for the temperature to drop before the staff enters the drying room to add oil and lubricate, which has the effect of improving production efficiency.
