During hot pressing, the air pipe and the jet nozzle retract into the inside of the mold. When hot pressing is completed, under the driving of the lifting cylinder, the mold moves upward, at this time, the jet nozzle extends to the outside of the mold and cleans it, and the debris generated by cleaning falls between the sub-conveying belts below.

[0033] In the embodiment, the automobile interior panel bending device is mainly divided into three parts: the feeding mechanism 1, the hot pressing mechanism 2 and the conveying mechanism 3. When the device is used, the plastic panels 303 to be processed are placed on the first conveying belt 301 at intervals, and then the double-shaft motor 102 is started and drives the linkage 103 to rotate counterclockwise. When one end of the swing arm 109 slides along the pressing groove 105, the swing arm 109 is high on the left and low on the right at this time, and the swing seat 111 drives the driving gear plate 113 to move downward, and the brake part 122 at the bottom of the hanger plate 120 moves downward and unlocks the bottom of the feeding gear 115.

When the plastic panel 303 moves between the hot pressing pile 204 and the mold 206 with the feeding gear 115, the plastic panel 303 is hot pressed by the mold 206 and the hot pressing pile 204 at this time. At this time, one end of the swing arm 109 slides along the lifting groove 106, and the swing arm 109 is low on the left and high on the right, and the brake part 122 at the bottom of the hanger plate 120 moves upward and locks the bottom of the feeding gear 115.

When the double-shaft motor 102 rotates counterclockwise, when the driving tooth plate 113 is engaged with the feeding gear 115, at this time, the connecting arm 114 is located at the left side of the shaft center. When the linkage 103 rotates counterclockwise, the connecting arm 114 moves from the left side to the right side, thereby driving the feeding gear 115 to rotate clockwise. When the driving tooth plate 113 is disengaged from the feeding gear 115, at this time, the connecting arm 114 is located at the right side of the shaft center. When the linkage 103 rotates counterclockwise, the connecting arm 114 moves from the right side to the left side, at this time, the feeding gear 115 remains in a stationary state.

[0038] Referring to the drawings Figure 2 - the drawings Figure 3 The bottom of the swing seat 111 is provided with a hanging rail 112, and the top of the driving tooth plate 113 is slidably arranged in the hanging rail 112.

[0042] Referring to the drawings Figure 1 - the drawings Figure 3, the outer side of the swing seat 111 is movably provided with a downwardly hanging plate 120, the middle part of the hanging plate 120 is provided with a slot 121, and the inner support frame 202 penetrates through the slot 121; the bottom of the hanging plate 120 is fixedly provided with a brake portion 122 matched with the feeding gear 115, when the swing arm 109 drives the driving tooth plate 113 to reciprocatingly swing up and down, the brake portion 122 locks and unlocks the bottom of the feeding gear 115.

[0043] In the embodiment, when one end of the swing arm 109 slides along the pressing groove 105, at this time, the swing arm 109 is high on the left and low on the right, and the swing seat 111 drives the driving tooth plate 113 to move downwardly, at this time, the brake portion 122 at the bottom of the hanging plate 120 moves downwardly and unlocks the bottom of the feeding gear 115. When one end of the swing arm 109 slides along the lifting groove 106, at this time, the swing arm 109 is low on the left and high on the right, and the brake portion 122 at the bottom of the hanging plate 120 moves upwardly and locks the bottom of the feeding gear 115, so as to avoid that the plastic plate 303 is accidentally loosened in the process of hot pressing.

[0044] Referring to the accompanying drawings Figure 5 - the accompanying drawings Figure 7 The bottom of the inner support frame 202 is installed with a hot pressing cylinder 203 between the two feeding gears 115, and the output end of the hot pressing cylinder 203 is installed with a hot pressing pile 204; the top of the outer support frame 201 is installed with symmetrical lifting cylinders 205, and the bottom of the lifting cylinders 205 is installed with a mold 206 matched with the hot pressing pile 204.

[0045] In the embodiment, when the plastic plate 303 moves to between the hot pressing pile 204 and the mold 206 along with the feeding gear 115, at this time, the mold 206 moves downwardly under the driving of the lifting cylinder 205 and cooperates with the suction cup 119 to extrude and fix the two sides of the plastic plate 303. Then the hot pressing cylinder 203 drives the hot pressing pile 204 to move upwardly to hot press the plastic plate 303.

[0046] Referring to the accompanying drawings Figure 5 - the accompanying drawings Figure 6 The middle part of the outer support frame 201 is installed with a fan 207, the bottom of the fan 207 is connected with an air pipe 208 penetrating through the mold 206, and the bottom of the air pipe 208 is provided with a jet nozzle 209.

[0047] In the embodiment, in the process of hot pressing, the air pipe 208 and the jet nozzle 209 are retracted into the inside of the mold 206. When the hot pressing is completed, the mold 206 moves upwardly under the driving of the lifting cylinder 205, at this time, the jet nozzle 209 extends to the outside of the mold 206 and cleans it, and the debris generated in the cleaning falls between the sub-conveying belts 305 below for subsequent centralized cleaning. When the suction cup 119 is accidentally out of order and the hot pressing interior trim 304 rises along with the mold 206, the air pipe 208 and the jet nozzle 209 can also assist the demolding.

[0048] Referring to the drawings Figure 1 and the drawings Figure 7 , the second conveying belt 302 is located outside the feeding gear 115, and is used to convey the hot-pressing interior trim part 304 after hot-pressing.

Under the conveying of the first conveying belt 301, when the plastic plate 303 moves directly below the mounting frame 117, the pump 118 and the suction cup 119 are started at this time, the connecting arm 114 moves from left to right at the connection with the linkage 103, so that the plastic plate 303 rotates clockwise with the feeding gear 115. When the plastic plate 303 moves between the hot pressing pile 204 and the mold 206 with the feeding gear 115, the plastic plate 303 is hot-pressed by the mold 206 and the hot pressing pile 204 at this time. At this time, the end of the swing arm 109 slides along the lifting groove 106, the swing arm 109 is low on the left and high on the right, and the locking part 122 at the bottom of the hanging plate 120 moves upward and locks the bottom of the feeding gear 115.

And when the linkage 103 rotates counterclockwise, the connecting arm 114 moves from right to left at the connection with the linkage 103, at this time the feeding gear 115 remains in a stationary state. After hot pressing is completed, the mold 206 moves upward under the driving of the lifting cylinder 205, at this time the air jet nozzle 209 extends to the outside of the mold 206 and cleans it. At this time, the plastic plate 303 is hot-pressed into a hot-pressed interior trim part 304 and is still adsorbed on the feeding gear 115 by the suction cup 119, when the feeding gear 115 rotates above the second conveying belt 302, the pump 118 is turned off at this time, and the hot-pressed interior trim part 304 falls onto the second conveying belt 302.
