Description

Technical Field

[0001] The present invention relates to the technical field of spraying technology, in particular to bottle inner wall spraying equipment and a spraying technology thereof. Background Art

[0002] The existing bottle inner wall spraying equipment is composed of three main mechanisms, namely, a clamping mechanism for clamping the bottle to be sprayed, a spraying mechanism for spraying the inner wall of the bottle, and a transmission mechanism for transporting the bottle liner. Although these mechanisms work together, in the actual spraying process, the linkage between the clamping mechanism, the spraying mechanism and the transmission mechanism is not very smooth, and manual transfer is required. This inefficient linkage method leads to a waste of time in the entire spraying process and reduces production efficiency. Specifically, due to the lack of close linkage and automated control between the various mechanisms, the operator needs to intervene frequently and manually transfer the bottle to ensure the smooth flow of the bottle from the clamping mechanism to the spraying mechanism and then to the transmission mechanism. This manual operation not only increases the labor intensity of the workers, but also leads to excessively long waiting time in the production link, seriously affecting the overall work efficiency and automation level. Therefore, a bottle inner wall spraying equipment and a spraying process thereof are needed to solve the above problems. Summary of the Invention

The two gears are connected by a chain transmission. The two gears are respectively fixed to the outer surfaces of the first connecting rod 220 and the second connecting rod 222. Then, the rotation of the support rod 217 drives the first connecting rod 220 to rotate through the profile rod 219. The rotation of the first connecting rod 220 drives the gear on the second connecting rod 222 to rotate through the gear and chain above, thereby driving the second connecting rod 222 to rotate. The rotation axes of the movable plate and the rotating plate 23 are respectively located on the same straight line, and the straight lines are parallel to each other, and the movable plate and the rotating plate 23 are staggered; The shaft-moving plate and the rotating plate 23 are parallel to each other and can cooperate with the support plate 21 and the connecting plate 25 to form a parallelogram. When one side rotates, it will drive the other sides to rotate in parallel. That is, the rotation of the rotating plate 23 will drive the connecting plate 25 to rotate in parallel, which can drive the clamping plate 26 to rotate in a horizontal state. It cooperates with the regulating mechanism 29 to clamp the bottle liner 6 on the transmission mechanism 5 and transport the bottle liner 6 to the spraying mechanism 4 for spraying through the slide rail mechanism 1. The limiting plate 28 can not only limit the two support plates 21, but also provide a support point for the motor and other mechanisms, thereby increasing the structural stability of the equipment. The two support plates 21 can be supported by the sliding rod 212 to increase the stability of the two support plates 21 during the sliding process. The regulating mechanism 29 includes two sliding holes 298 formed in the top of the bracket 27. Two slide plates 297 are slidably connected to the inner walls of the sliding holes 298. The tops of the two slide plates 297 are fixedly connected to push plates 296. The bottoms of the two slide plates 297 are fixedly connected to the top of the support plate 21. The regulating mechanism 29 further includes a support 291 fixed to the top of the bracket 27. The inner wall of the support 291 is fixedly connected to two electric push rods 292.

The inner wall of each set of rotating plates 294 is rotatably connected to a support block 295. One side of the support block 295 is fixedly connected to one side of the push plate 296. According to the above embodiment, the telescopic function of the electric push rod 292 cooperates with the rotating plate 294 to drive the push plate 296 to move, thereby driving the support plate 21 to move through the slide plate 297, thereby adjusting the distance between the clamping plates 26; A bottle inner wall spraying process, the specific process includes the following steps: 1) Place the bottle 6 on the top of the transmission mechanism 5 and start the transmission mechanism 5 to perform transmission pause operation; 2) The electric push rod 292 contracts and drives the fixed block 293 to move. The movement of the fixed block 293 drives the angle between the rotating plate 294 and the electric push rod 292 to increase. At this time, the two push plates 296 move outward. The movement of the push plates 296 drives the sliding plate 297 to move. The movement of the sliding plate 297 drives the support plate 21 to move. The support plate 21 moves through the rotating plate 23 and the shaft-moving plate via the connecting plate 25, driving the clamping plate 26 to move. During this process, the distance between the two clamping plates 26 gradually increases. 3) The motor drives the shaft 215 to rotate, and drives the support rod 217 to rotate through the bevel gear set 216, which then enables the profile rod 219 to rotate. The profile rod 219 in the rotating state drives the first rotating rod 22 to rotate through the chain gear set 221, and the clamping plate 26 is rotated via the rotating plate 23 and the shaft-moving plate; 4) As the two splints 26 rotate downward, they approach the top of the conveying mechanism 5. When the bottle liner 6 on the conveying mechanism 5 reaches the center of the two splints 26, the conveying mechanism 5 stops transporting the bottle. 5) The motor drives the two clamping plates 26 to be located outside the bottle liner 6. Then, the electric push rod 292 extends to move the two push plates 296 toward the position of the support 291, driving the two clamping plates 26 to clamp the bottle liner 6. The motor rotates in the opposite direction to drive the clamping plates 26 to rotate upward to the initial position. 6) The slide rail mechanism 1 drives the bottle liner 6 on the clamping mechanism 2 to move toward the spraying mechanism 4 through the slide seat 3. The output end of the spraying mechanism 4 passes through the bottle mouth of the bottle liner 6 and enters the interior of the bottle liner 6 to spray the interior of the bottle liner 6; 7) After spraying is completed, the slide rail mechanism 1 drives the clamping mechanism 2 to recover. Then, the clamping mechanism 2 drives the bottle liner 6 to be placed on the top of the conveying mechanism 5 and controls the clamping plate 26 to move away from the bottle liner 6. The conveying mechanism 5 transports the sprayed bottle liner 6 away from the center of the two clamping plates 26 and transports the bottle liner 6 to be sprayed to the center of the two clamping plates 26. The above operation is repeated to complete the spraying process.

[0017] Working principle: like Figure 1-6As shown, the bottle 6 is placed on the top of the transmission mechanism 5, and the transmission mechanism 5 is turned on for transmission pause operation. The electric push rod 292 contracts and drives the fixed block 293 to move. The movement of the fixed block 293 drives the angle between the rotating plate 294 and the electric push rod 292 to increase. At this time, the two push plates 296 move outward, and the movement of the push plates 296 drives the movement of the slide plate 297. The movement of the slide plate 297 drives the movement of the support plate 21. The movement of the support plate 21 drives the movement of the clamping plate 26 through the rotating plate 23 and the shaft-moving plate via the connecting plate 25. During this process, the distance between the two clamping plates 26 gradually increases. The motor drives the shaft 215 to rotate, and drives the support rod 217 to rotate through the bevel gear set 216. The support rod 217 rotates through the groove 218 to drive the profile rod 219 to rotate, and the profile rod 219 in the rotating state drives the first rotating rod 22 to rotate through the chain gear set 221, and the clamping plate 26 is rotated through the rotating plate 23 and the shaft-moving plate. The rotating plate 23 and the shaft-moving plate are parallel, and the rotating plate 23 rotates, which causes the shaft-moving plate to rotate as well, thereby enabling the connecting plate 25 to move in a horizontal upward and downward rotation manner, that is, the connecting plate 25 is always in a parallel state with the slide rail mechanism 1. The two clamping plates 26 will approach the transmission mechanism 5 during the downward rotation. The bottle liner 6 on the transmission mechanism 5 will stop transportation after reaching the center position of the two clamping plates 26. The two clamping plates 26 are driven by the motor to be located outside the bottle liner 6 and The bottle 6 will not come into contact with the bottle liner 6. Then, the electric push rod 292 is extended to move the two push plates 296 toward the position of the support 291, driving the two clamping plates 26 to clamp the bottle liner 6. The motor rotates in the opposite direction to drive the clamping plates 26 to rotate upward to the initial position. The slide rail mechanism 1 drives the bottle liner 6 on the clamping mechanism 2 to move toward the spraying mechanism 4 through the slide seat 3. The output end of the spraying mechanism 4 passes through the bottle mouth of the bottle liner 6 and enters the interior of the bottle liner 6 to spray the interior of the bottle liner 6. After the spraying is completed, the slide rail mechanism 1 drives the clamping mechanism 2 to recover. Then, the clamping mechanism 2 drives the bottle liner 6 to be placed on the top of the conveying mechanism 5 and controls the clamping plates 26 to move away from the bottle liner 6. The conveying mechanism 5 transports the sprayed bottle liner 6 away from the center of the two clamping plates 26 and transports the bottle liner 6 to be sprayed to the center of the two clamping plates 26. The above operations are repeated to complete the spraying process.

The profile rod (219) in the rotating state drives the first rotating rod (22) to rotate through the chain gear set (221), and the clamping plate (26) is made to rotate via the rotating plate (23) and the shaft-moving plate; 4) When the two clamps (26) rotate downward, they will approach the top of the transmission mechanism (5), and the bottle liner (6) on the transmission mechanism (5) will be suspended after reaching the center position of the two clamps (26); 5) The two clamping plates (26) are positioned outside the bottle liner (6) by the driving of the motor, and then the two push plates (296) are moved toward the position of the support (291) by the extension of the electric push rod (292), driving the two clamping plates (26) to clamp the bottle liner (6), and the reverse rotation of the motor drives the clamping plates (26) to rotate upward to the initial position; 6) The slide rail mechanism (1) drives the bottle liner (6) on the clamping mechanism (2) to move toward the spraying mechanism (4) through the slide seat (3); the output end of the spraying mechanism (4) passes through the bottle mouth of the bottle liner (6) and enters the interior of the bottle liner (6) to spray the interior of the bottle liner (6); 7) After the spraying is completed, the slide rail mechanism (1) drives the clamping mechanism (2) to recover, and then the clamping mechanism (2) drives the bottle liner (6) to be placed on the top of the transmission mechanism (5), and controls the clamping plate (26) to be moved away from the bottle liner (6). The transmission mechanism (5) transports the sprayed bottle liner (6) away from the center of the two clamping plates (26), and transports the bottle liner (6) to be sprayed to the center of the two clamping plates (26). The above operation is repeated to complete the spraying process.
