Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe production equipment, in particular to a bottom tray cleaning and oiling machine for concrete pipe forming. Background Art

[0002] Reinforced concrete drainage pipes are widely used in modern urban infrastructure and rural farmland water conservancy construction and renovation projects. In particular, with increasingly stringent environmental protection requirements, rainwater and sewage diversion projects require large quantities of drainage pipes. Current production processes mostly utilize just-in-time demoulding, which necessitates a sufficient number of bottom trays to meet daily production needs. After daily use, bottom trays must be cleaned and oiled before reuse; otherwise, the product's appearance quality cannot be guaranteed.

[0003] Existing bottom trays after production are manually cleaned with a grinder to remove the remaining concrete slag or mortar residue on the bottom tray. After cleaning, a layer of protective grease is applied to the working surface of the bottom tray with a brush. The cleaning process generates dust, which is not environmentally friendly and affects the health of workers. Utility Model Content

[0052] The working process of this utility model:

[0053] 1) Manually place the bottom tray on the small turntable 11 located on the loading station 8 and position it using the positioning claws 17.

[0054] 2) The large turntable rotation drive motor 6 drives the first gear 7 to rotate, which is transmitted through the first ring gear 53 to drive the large turntable 3 to rotate, thereby rotating the small turntable 11 on the loading station 8 to the cleaning station 10, and at the same time, the small turntable 11 on the oiling station 9 is rotated to the loading station, and then manually loaded. At the same time, the bottom tray cleaning mechanism 20 cleans the bottom tray on the cleaning station 10. The specific working principle of the bottom tray cleaning mechanism 20 is as follows: the first vertical displacement module 25 and the first lateral displacement module 26 cooperate to drive the grinding head 32 to the bottom tray, and the grinding head rotation motor 33 drives the grinding head 32 to rotate to grind the bottom tray. The first vertical displacement module 25 and the first lateral displacement module 26 cooperate to adjust the up and down and left and right grinding positions. The small turntable drive motor 15 drives the corresponding small turntable 11 to rotate, so that the grinding head 32 can grind along the circumferential direction.

[0055] Since the shape of the surface of the workpiece to be cleaned is irregular, the grinding head angle needs to be continuously changed during cleaning so that the grinding head can fully fit the workpiece. When adjusting the angle, the first driving motor 36 drives the first driving gear 37 to rotate, driving the first sector gear 35 to rotate, and driving the grinding head 32 to adjust the angle, thereby achieving comprehensive grinding of the bottom tray without dead angles.

[0056] 3) After the bottom tray cleaning mechanism 20 is polished, the large turntable rotation drive motor 6 drives the first gear 7 to rotate, which is transmitted through the first ring gear 53 to drive the large turntable 3 to rotate, and the small turntable 11 on the oiling station 9 is rotated to the loading station, and then manually loaded, and the small turntable 11 on the loading station 8 is rotated to the cleaning station 10 for cleaning, and the polished bottom tray is rotated to the oiling station 9 for oiling. The working principle of the bottom tray oiling mechanism 19 is as follows: the second vertical displacement module 39 and the second horizontal displacement module 40 cooperate to place the oiling brush 45 on the working surface of the bottom tray, and at the same time, the position of the oiling brush 45 is adjusted during the oiling process, and the corresponding small turntable 11 is driven to rotate by the small turntable drive motor 15, which drives the bottom tray on the small turntable 11 to rotate, thereby realizing circumferential oiling;

[0057] Since the shape of the surface of the workpiece to be oiled is irregular, the angle of the brush head needs to be continuously changed during oiling so that the brush head can fully fit the workpiece. When adjusting the angle, the second steering drive motor 49 and the second rotation drive motor 49 drive the second drive gear 50 to rotate, driving the rotation of the second sector gear 48, and driving the angle adjustment of the oiling brush 45.

[0058] 4) After the polishing and oiling processes are completed, the large turntable rotates and drives the motor 6 to drive the first gear 7 to rotate, which is then transmitted through the first ring gear 53 to drive the large turntable 3 to rotate, and the small turntable 11 on the oiling station 9 is rotated to the loading station, and then manually loaded. The small turntable 11 on the loading station 8 is rotated to the cleaning station 10 for cleaning, and the small turntable 11 on the cleaning station is rotated to the oiling station 9 for oiling.

[0059] 5) Repeat step 4).
