Background
The plastic sheet pneumatic thermoforming machine is a forming equipment which depends on compressed air to stretch and pressurize a plastic sheet softened by heating, so that the plastic sheet is tightly attached to the surface of a mold, and a product is formed after cooling and shaping. Because plastic sheet is before carrying, its both ends are pressed from both sides respectively on two caterpillar tracks, then two caterpillar tracks are carried plastic sheet forward, and plastic sheet passes through the infrared radiation heating of electric stove, and after plastic sheet softened, its middle part often all can droop, and according to the requirement of forming process, two caterpillar tracks of this moment need possess the function of automatic opening, make the interval increase of two caterpillar tracks to let the condition that plastic sheet mid portion droops obtain effectual improvement.
In order to realize the automatic adjustment of the widths of the two caterpillar tracks in the conveying process, the chinese patent application No. CN201911211021.7 discloses a caterpillar track device capable of automatically adjusting the widths of the caterpillar tracks, which comprises a frame, two caterpillar tracks, a front end width adjusting assembly, a rear end width adjusting assembly and at least one middle width adjusting assembly, and is characterized in that: the front end part width adjusting assembly, the rear end part width adjusting assembly and the middle width adjusting assembly respectively comprise a driving motor, an adjusting screw rod and two translation seats, the driving motor is installed on the rack, the adjusting screw rod is rotatably installed on the rack and is in transmission connection with an output shaft of the driving motor, the adjusting screw rod is provided with a left screw rod section and a right screw rod section with opposite thread turning directions, the two translation seats are respectively arranged on the two chain rails, a left screw hole meshed with the left screw rod section is formed in the translation seat on the left side, and a right screw hole meshed with the right screw rod section is formed in the translation seat on the right side; the caterpillar track device further comprises a controller and a plurality of encoders, the encoders are in the same number with the adjusting screw rods and are in one-to-one correspondence with the adjusting screw rods, the encoders are fixedly mounted on the end portions of the corresponding adjusting screw rods respectively, the encoders are electrically connected with corresponding input ends of the controller respectively, and the driving motors are electrically connected with corresponding output ends of the controller respectively. The caterpillar track device enables the plastic sheet to be gradually stretched outwards and leveled by being pulled by the chains on the caterpillar tracks in the heating and conveying process by adjusting the widths of the two caterpillar tracks in the heating and conveying process of the plastic sheet, keeps the plastic sheet in a tensioning state in the heating process, and simultaneously detects the actual displacement of the corresponding parts of the two caterpillar tracks in real time through the encoder, so that the accurate automatic adjustment of the widths of the two caterpillar tracks is realized. For a single width adjusting assembly, the displacement of two translation seats achieved by rotating the output shaft of the motor for a certain number of turns needs to be compared with the displacement preset in the controller, and then corresponding fine adjustment is performed.
However, since the position and the amplitude of the expansion of the plastic sheet are not predictable in the process of heat transfer, when the displacement of the two translation seats reaches the preset displacement, the plastic sheet may thermally expand only on one side or expand unevenly on both sides, and the motor cannot adjust the distance between the two caterpillar tracks according to the actual expansion condition of the plastic sheet; and because the translation seat is installed on the caterpillar track, and two caterpillar tracks are generally in the state of opening gradually after adjusting, translation seat can be in relative inclined state in accommodation process, make screw on the translation seat and adjusting screw's screw rod section chucking state appear, lead to the translation seat to be difficult to follow adjusting screw translation, after the use of a period of time, great wearing and tearing just appear easily in translation seat and adjusting screw, cause the flexibility of adjustment relatively poor, often need maintain or change spare part, influence the life of caterpillar track device.
