Wherein, the traction mechanism 8 includes a motor, a screw rod and a connecting plate. The screw rod is arranged on the machine base in a rotational direction along the length direction of the machine base. The motor is installed on the machine base, and its output shaft is connected to the screw rod in a transmission manner. The bottom end of the connecting plate is sleeved on the screw rod and is threadedly connected with the screw rod. The top end is fixed on the stretching mechanism. The rotation of the motor drives the screw rod to rotate, and the rotation of the screw rod drives the connecting plate to move forward and backward, thereby driving the stretching mechanism to move. During operation, the stretching mechanism 2 clamps and stretches the thick plate, and the traction mechanism 8 drives the stretching mechanism 2 to move forward between the upper oven 3 and the lower oven 4. After the upper oven 3 and the lower oven 4 heat the thick plate, the traction mechanism 8 drives the stretching mechanism 2 to move to the blister mold 5 again. The stretching mechanism 2 releases the thick plate and resets under the action of the traction mechanism 8 to operate the next thick plate, and the blister mold 5 processes the thick plate on it. The thermoplastic sheet processing machine tool of this embodiment divides the stretching heating and processing into different areas, which can effectively improve the processing efficiency; at the same time, the symmetrical design of the upper oven and the lower oven makes the thick plate heated more evenly, which is useful for subsequent processing.

[0022] In this embodiment, the stretching mechanism 2 includes a support frame 21, a pair of transverse guide plates 22, a pair of longitudinal guide plates 23, a first driving mechanism 24, a second driving mechanism 25, four slide plates 26 and a plurality of clamps 27. The support frame 21 is installed on a plurality of sliders 7. The transverse guide plates 22 and the longitudinal guide plates 23 are arranged perpendicular to each other. The first driving mechanism 24 and the second driving mechanism 25 are installed on the support frame 21. The driving end of the first driving mechanism 24 is connected to the pair of transverse guide plates 22 and drives the pair of transverse guide plates 22 to move toward or in the opposite direction. The driving end of the second driving mechanism 25 is connected to the pair of longitudinal guide plates 23 and drives the pair of longitudinal guide plates 23 to move toward or in the opposite direction. The slide plate 26 is provided with a transverse through hole 261 and a longitudinal through hole 262. The slide plate 26 is slidably sleeved on two adjacent transverse guide plates 22 and the longitudinal guide plates 23 through the transverse through hole 261 and the longitudinal through hole 262 respectively. The plurality of clamps 27 are respectively installed on the transverse guide plate 22 and the longitudinal guide plate 23. The first driving mechanism 24 and the second driving mechanism 25 are started, respectively driving the two transverse guide plates 22 and the two longitudinal guide plates 23 to move toward or in opposite directions. Since the four slide blocks 26 are mounted on the adjacent transverse guide plates 22 and the longitudinal guide plates 23 through the transverse through holes 262 and the longitudinal through holes 262, the two transverse guide plates 22 and the two longitudinal guide plates 23 move toward or in opposite directions, driving the multiple clamps 27 thereon to move, clamping the film for stretching, so that the film is subjected to uniform force during the stretching process, thereby ensuring the quality of the film stretching.

[0023] In this embodiment, since the second driving mechanism 25 and the first driving mechanism 24 have the same structure, the second driving mechanism 25 is used to drive the longitudinal guide plate 23 to move, and the first driving mechanism 24 is used to drive the transverse guide plate 22 to move. Here, only the structure of the first driving mechanism 24 is described. The first driving mechanism 24 includes four driving electric cylinders 241 and four connecting plates 242. The four driving electric cylinders 241 are slidably arranged on both sides of the support frame 21. Two driving electric cylinders 241 located at the same position are arranged in opposite directions. The telescopic ends of the driving electric cylinders 241 are connected to the support frame 21, and the two ends of a pair of transverse guide plates 23 are connected to the four driving electric cylinders 241 through connecting plates 242. The telescopic ends of the driving electric cylinders 241 are extended and retracted to drive the driving electric cylinders 241 to move, so that the two transverse guide plates 22 connected to the driving electric cylinders 241 move toward or in opposite directions.

[0024] In this embodiment, the clamp 27 includes a lower fixed seat 271, a first support block 272, a second support block 273, a connecting rod 274, a connecting block 275, a support rod 276, a pressing block 277, and a cylinder 278. The lower fixed seat 271 is installed on the transverse guide plate 22 and the longitudinal guide plate 23. The first support block 272 is fixed on the lower fixed seat 271. The cylinder 278 is installed on the first support block 272 with its telescopic end facing forward. The second support block 273 is fixed on the lower fixed seat 271 and is located at the In front of the first support block 272, one end of the connecting rod 274 is hinged on the telescopic end of the cylinder 278, and the other end thereof is hinged at the lower left side of the second support block 273. The end of the support rod 276 is hinged at the upper right side of the second support block 273. One end of the connecting block 275 is hinged at the telescopic end of the cylinder 278, and the other end thereof is hinged at the middle part of the support rod 276. The bottom of the connecting block 275 rolls on the second support block 273, and the pressing block 277 is installed at the outer end of the support rod 276. The telescopic end of the cylinder 278 drives the connecting rod 274 to swing forward on the second support block 273. Since the top of the connecting block 275 is also connected to the telescopic end of the cylinder 278, the top of the connecting block 275 moves forward, and its bottom presses on the second support block 273, so that the connection between the connecting block 275 and the support rod 276 moves downward. Since the end of the support rod 276 is hinged on the second support block 273, the front end of the support rod 276 moves downward to drive the pressing block 277 to press the thick plate on the lower fixed seat 271. When the thick plate is to be released, the cylinder 278 retracts after extension, the above components are reset, and the support rod 276 drives the pressing block 277 to leave the thick plate. The clamp can quickly clamp and release thick plates.

[0025] In this embodiment, the plurality of clamps 27 are equidistantly distributed on the transverse guide plate 22 and the longitudinal guide plate 23, so that the thick plate is clamped and stretched with more uniform force. The upper oven 3 and the lower oven 4 are symmetrically distributed about the stretching mechanism 2, so that the thick plate is stressed more evenly.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
