In addition, a group of conveying lines 31 positioned inside the oven 3 are correspondingly arranged at the outlet ends of the two feeding machines respectively.

After the carrier plate 4 with the bathtub body is conveyed to the feeder 2 by the conveying line 1 at the inlet end of the feeder 2, the bathtub body is continuously conveyed under the work of the conveying belt 26; when the front end of the carrier plate 4 carrying the cylinder body touches the roller of the first travel switch 28, the first travel switch 28 sends a trigger signal to the control device, and the control device sends a signal for stopping conveying to the conveying line 1 at the inlet side of the feeding machine 2, so that the conveying line 1 stops conveying the cylinder body to the feeding machine 2, and collision and breakage between the cylinder bodies on the feeding machine are avoided. At this moment, the blocking cylinder 12 plays a role of stopping the carrier plate, and the carrier plate 4 moves in the conveying direction under the operation of the chain conveyor 11 until the trapezoidal opening 41 of the carrier plate 4 contacts with the stop lever of the blocking cylinder 12, and the carrier plate stops advancing. Before the carrier plate 4 contacts the blocking cylinder 12, the carrier plate will collide with the roller of the third stroke switch 13 arranged at the rear side of the blocking cylinder 12, the third stroke switch 13 sends a signal to the control device to indicate that the carrier plate has moved to the current position, and the carrier plate stops at the current position due to the non-action of the blocking cylinder, so that the control device controls the working state of the blocking cylinder at the rear side, and the chain conveyor 11 is prevented from conveying more carrier plates to the current position, so that the cylinder bodies on the carrier plate collide with each other, and the cylinder bodies are conveyed in order. When the feeding machine 2 sends a feeding signal to the control device, the control device controls the blocking cylinder 12 to release the carrier plate and allow the carrier plate to advance toward the feeding machine. After the carrier plate 4 is released, the blocking cylinder 12 and the third stroke switch 13 are automatically reset, and after the control device receives a signal, the blocking cylinder on the rear side is controlled to release the carrier plate, so that the chain conveyor 11 continues to convey the carrier plate 4. Because be provided with a plurality of third travel switch 13 and block cylinder 12 on the transfer chain 1, through third travel switch 13 and the cooperation work who blocks cylinder 12, realize the well orderly transport of cylinder body, prevent to cause the cylinder body to damage because of colliding between the cylinder body.

After the carrier plate moves from the conveying line 1 to the feeder 2, under the operation of the conveying belt 26, the carrier plate continues to advance after touching the first travel switch 28 until it touches the second travel switch 27; at this moment, the control device receives the trigger signals of the first travel switch 28 and the second travel switch 27 respectively, and the control device controls the driving mechanism 29 to stop operating, so that the conveying belt 26 stops conveying work, the cylinder body stays on the feeding machine 2, and the control device is waited for the oven 3 to send a feeding signal; meanwhile, the blocking cylinder 12 closest to the feeding machine 2 can be controlled to work, the blocking cylinder is enabled to continue stopping the carrier plate, and the conveying line 1 is suspended from conveying the cylinder body to the feeding machine 2 until the cylinder body on the feeding machine 2 is conveyed into the oven.

In this embodiment, the contact surface between the conveying belt 26 and the carrier plate 4 is rough, and the outer side surface of the conveying belt 26 is provided with a plurality of protruding points for increasing the friction between the conveying belt and the carrier plate, so that the carrier plate does not slip during conveying, and the driving mechanism is prevented from doing too much idle work and increasing energy consumption.

Because the space in the curing production line is limited, the number of the cylinder bodies can be contained, in the embodiment, each group of conveying lines 31 in the oven 3 is arranged into an upper working area and a lower working area (namely, two conveying lines which are arranged in parallel up and down), and the bathtub curing production line is changed into a four-channel heating curing production line.

The control device further controls the working state of the lifting mechanism 22 of the feeding machine 2 according to the feeding signals sent by the upper working area and the lower working area in the oven, if the feeding signals are sent to the control device by the upper working area of the oven, the lifting mechanism 22 of the feeding machine 2 corresponding to the upper working area is started, the lifting mechanism 22 lifts the bottom frame 21, then the control device controls the driving mechanism 29 to work, and the cylinder body is conveyed to the upper working area of the oven through the conveying belt 26. At the conclusion, the first and second travel switches 28, 27 will be reset. Then, the lifting mechanism 22 lowers the base frame 21, and the control device controls the conveyor line 1 to continue conveying the cylinder to the feeder 2 after receiving a signal that the lifting mechanism completes the lowering operation of the base frame. Similarly, if the lower working area of the oven sends a feeding signal to the control device, the control device controls the driving mechanism 29 of the feeder 2 corresponding to the lower working area to operate, so as to convey the cylinder to the lower working area of the oven through the conveying belt 26. At the conclusion, the first and second travel switches 28, 27 will be reset. Subsequently, the control device controls the conveyor line 1 to continue conveying cylinders to the feeder 2.

the outlet side of the conveying line 31 arranged in the oven can be provided with a liftable discharging conveying mechanism, the structure of the discharging conveying mechanism is the same as that of the feeding machine, the structure and the working principle of the conveying line 31 are basically the same as those of the conveying line 1, and the conveying line 31 is also provided with a blocking cylinder 12 and a third stroke switch 13. After a blocking cylinder in the oven, which is closest to the feeding machine, releases the carrier plate, the working position is in an idle state, and after the control device receives a signal of the blocking cylinder (namely a feeding signal), the control device correspondingly controls the driving device to work, so that the driving device opens a corresponding door body, and the feeding machine can conveniently convey the cylinder body to the idle working position.

According to the invention, two groups of conveying lines 31 are arranged in the oven, and the feeding machines are correspondingly arranged to convey the cylinder body for each conveying line 31 in the oven, so that the space utilization rate is improved, and the curing treatment capacity of the oven is improved; and through the cooperation work of first travel switch, second travel switch, third travel switch and blocking the cylinder, the position of intelligence orderly control cylinder body avoids colliding mutually between the cylinder body, realizes the automatic cylinder body of carrying, reducible human input.

In conclusion, the bathtub curing production line provided by the invention has the advantages of space saving, high efficiency and high intelligent automation degree. Compared with the prior art, the four conveying lines are arranged in the drying oven, so that the processing capacity of the drying oven is greatly increased, and the space utilization rate is improved; two feeding machines are arranged outside the oven, and the lifting of the feeding machines is realized through a lifting mechanism, so that the bathtub is conveyed to a conveying line positioned at the upper part of the oven; set up first travel switch, second travel switch, third travel switch and block the cylinder for the bathtub can be carried to the material loading machine in good order, so that the material loading machine comes for four inside transfer chains of oven to carry the bathtub according to the behavior of oven, and, can avoid the bathtub to bump so that appear damaging on transfer chain, material loading machine, and visible intelligent degree of automation is high.
