Detailed Description
The present invention is further described below in conjunction with the following detailed description, which is intended to further illustrate the principles of the invention and is not intended to limit the invention in any way, but is equivalent or analogous to the present invention without departing from its scope.
With reference to the attached drawings.
As shown in the figure, the automatic coating production line of the bogie component comprises a circulating chain 2 which is driven by a driving mechanism 1 and forms closed-loop operation, wherein a hanging station 4, a dip-coating workshop 6 and a drying chamber 7 are sequentially arranged on an operation channel of the circulating chain 2; the dip-coating member 54 is suspended on the endless chain 2 by a suspension chain 53; a dip-coating tank 51 for loading paint is arranged in the dip-coating workshop 6, a descending section, a horizontal section and an ascending section are arranged at the part of the circulating chain 2 above the dip-coating tank 51, the inclination angle of the ascending section circulating chain 2 and the horizontal plane is more than 30 degrees, and the tail end of the ascending section is provided with a photoelectric sensor for sensing the ascending dip-coating component 54 and stopping the circulating chain 2 and a time relay for starting the circulating chain to continue to run.
The hanging chains 53 for hanging the dip member 54 are two ones arranged in parallel, and the length of one hanging chain 53 arranged along the front end of the travel of the endless chain 2 is smaller than that of the hanging chain 53 arranged at the rear end, and the dip member 54 is formed to have an inclination angle of more than 30 degrees with the ground when hanging at the rising section.
The dip-coating tank 51 is 1-1.5m deep, 3-4m long and 0.4-0.6m wide, and three pneumatic stirrers are arranged in the dip-coating tank 51 to stir paint liquid.
The dip-coating workshop 6 and the drying chamber 7 are of a communicated labyrinth type closed structure and are provided with a negative pressure tail gas treatment system.
The driving mechanism 1 is arranged behind the hanging station 4 and on the circulating chain 2 at the front end of the dip-coating workshop 6, and the driving mechanism 1 comprises a driving motor and a speed reducer.
The circulating chain 2 at the rear end of the drying chamber 7 is provided with a circulating chain tensioning device 3.
As shown in the figure, a cross rod or pinch plate hanging and dipping component 54 is hung on the circulating chain 2 through a hanging chain 53 at a hanging station 4, and after the cross rod or pinch plate is fed, the circulating chain 2 carries the dipping component 54 to move forwards at a certain speed. The endless chain 2 runs downward while running above the dip tank 51, and as shown in fig. 2, the endless chain 2 runs horizontally again while running downward to a proper position to complete the dip coating of the dip coating member 54. The dip-coating member 54 after completion of the dip coating moves out of the dip tank along with the circulating chain 2 running upward.
During the process that the dip-coating member 54 moves out of the dip tank 51 and then the suspension chain 53 moves upward along the track of the endless chain 2, the excess paint on the surface of the dip-coating member 54 drips downward. The photoelectric sensing device senses that the dip-coating member 54 runs to a set position, the time relay is triggered to start hovering timing, and the dip-coating member 54 is in the position with the maximum included angle and does not hover within the set time, so that the leveling of paint liquid is facilitated.
After the dip-coating member 54 is suspended and free to level, the circulating chain 2 drives the dip-coating member 54 to move upwards along the track, and the dip-coating member continues to move forwards along the horizontal direction, enters the drying chamber 7, passes through the drying chamber 7 and then moves to the suspension station 4. The dip coating member 54 is removed from the suspension chain 53, and the circulation chain 2 continues to run to perform the circulation operation.
In order to ensure that the dip-coating member 54 moves out of the dip-coating groove 51 and then the excessive paint on the surface of the dip-coating member 54 flows more quickly and completely, during the period that the dip-coating member 54 which finishes dipping paint is folded upwards to the horizontal segment along with the circulating chain 2, the photoelectric sensor senses that the dip-coating member 54 moves to a set stop position, and the included angle between the dip-coating member 54 and the ground in the hovering state is the largest. The dip-coating member 54 is suspended for 1-5min by using the photoelectric sensor and the time relay to control the circulating chain 2, so that the redundant paint liquid on the dip-coating member 54 is promoted to drip as soon as possible, and the surface of the dip-coating member 54 is ensured to be flat and have no obvious sagging. After the set rest time is over, the circulation chain 2 carries the dip-coating member 54 to continue to move forwards, and the subsequent dip-coating member 54 suspended on the circulation chain 2 continues to finish the processes of paint dipping, hovering, leveling and drying in the same step in the forward movement process.
The hovering time is selected in a range by combining conditions such as environment temperature, and the hovering time is shorter when the temperature is higher; the lower the temperature, the longer the hover time. The production line is suspended for 1-5 min. After the hovering time set by the time relay is over, the circulation chain 2 is triggered to continue to move forward and enter the drying chamber 7.
The depth of the paint dipping groove 51 is 1-1.5m, the length is 3-4m, and the width is 0.4-0.6 m. 3 air-driven stirrers are arranged at intervals to stir the paint liquid, so as to ensure that the paint liquid in the paint dipping tank 51 is uniformly mixed.
