Description

Technical Field

[0001] This invention relates to the field of vacuum forming technology for thick sheet materials, and specifically to an automatic feeding vacuum forming device for thick sheets with preheating function. Background Technology

[0002] In today's rapidly developing plastics industry, the application of thick sheet vacuum forming is constantly expanding due to its advantages such as wide material availability, low cost, recyclability, and good plasticity. It is widely used in product design and manufacturing for medical equipment, textile machinery, automotive accessories, precision electronics, and cosmetics, among many other fields. However, existing equipment for thick sheet vacuum forming typically heats and shapes the sheet material directly using a single heating device. This direct heating results in uneven heating of the sheet surface and a long processing time, thus affecting the processing quality. Furthermore, most existing equipment requires manual loading and unloading of the sheet material, which is time-consuming and labor-intensive.

[0003] A Chinese utility model patent with publication number CN217395671U provides a thick sheet vacuum forming processing device, which includes a vacuum forming cavity. Vacuum pumps are installed on both sides of the vacuum forming cavity, and a flow channel is provided between the vacuum pumps and the vacuum forming cavity. The flow channel and the vacuum forming cavity are interconnected. A sealing plate is installed on the vacuum forming cavity, and the sealing plate is connected to the vacuum forming cavity by an insertion groove. This allows plastic blanks to be vacuum formed, making vacuum forming processing more convenient and meeting the needs of vacuum forming operations. A lifting rod and a lifting pad are provided at the bottom of the vacuum forming cavity, which can directly lift the plastic part when removing it, making it easier to remove the plastic part.

[0004] Although it makes it easier to remove parts after the thick sheet is formed, it cannot solve the problems of uneven heating during the processing of thick sheet and automated loading and unloading, so the processing efficiency is still not high enough. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic feeding thermoforming device for thick sheets with preheating function. The device includes a frame, a stacking plate at the front end of the frame, and a molding mechanism at the rear end of the frame. A feeding mechanism is located at the front end of the frame, a heating mechanism at the rear end of the feeding mechanism, and a dropping mechanism at the rear end of the molding mechanism. The feeding mechanism includes an adsorption component, a support component, and a transmission component located below the adsorption component.

[0013] As a preferred embodiment, the transmission assembly further includes a servo motor c fixedly mounted on one side of the connecting bracket and a transmission rod c driven by the servo motor c.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention includes a transmission component that drives the heating furnace to move between the heat-conducting plate and the molding mechanism. When the transmission component transports the thick sheet to the heat-conducting plate, the heating furnace and the heat-conducting plate work together to preheat the sheet. The preheated sheet is then transferred to the molding mechanism by the transmission component. Simultaneously, the heating furnace also moves to the molding mechanism by the transmission component. The cooperation between the heating furnace and the molding mechanism completes the molding of the thick sheet. The preheating process ensures that the surface of the thick sheet is heated more evenly during molding, preventing uneven heating and cracking caused by direct heating from a single heating device. Furthermore, it significantly reduces the processing time required for heating and molding, thus improving processing efficiency.

[0019] 2. This invention is equipped with a transmission component, which automatically and intermittently adsorbs the thick sheet material placed on the stacking plate through the adsorption component, and drives the thick sheet material to be transported backward by the rotary chain a. After the thick sheet material is shaped, the rotary chain a and the guide cover cooperate to make the shaped thick sheet material automatically fall off to the unloading mechanism below. The unloading mechanism outputs the thick sheet material, realizing the automated loading and unloading of thick sheet material. This solves the problem that the existing vacuum forming equipment still requires manual handling of thick sheet material, which is time-consuming, labor-intensive, and affects the continuity of processing.

[0020] 3. This invention is equipped with a bearing component and a pin on the rotary chain a. When the adsorption component adsorbs the thick sheet material, the servo cylinder in the bearing component drives the mounting frame a to rotate inward. The rollers support the bottom of the thick sheet material. As the rollers rotate inward with the mounting frame and support the thick sheet material, they lift the thick sheet material a certain distance. After the thick sheet material is lifted, the pin on the rotary chain a can be inserted into the thick sheet material, thus enabling the rotary chain a to drive the thick sheet material backward. When the rotary chain a drives the thick sheet material to the end, the thick sheet material is deflected downward under the action of the guide cover, automatically detaches from the rotary chain a, and automatically falls into the unloading mechanism below to complete the output. The processing is highly continuous, the degree of automation is high, and the transmission is more stable.

[0021] In summary, this invention has the advantages of more uniform heating of thick sheet materials, better product quality, effectively shortened processing time, high processing efficiency, strong processing continuity, saving time and effort, and good linkage effect between various components, making it suitable for the field of thick sheet material vacuum forming technology.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1 to 11As shown, an automatic feeding thermoforming device for thick sheets with preheating function includes a frame 1, a stacking plate 2 disposed at the front end of the frame 1, and a shaping mechanism 3 disposed at the rear end of the frame 1. The device is characterized in that a feeding mechanism 4 is disposed at the front end of the frame 1, a heating mechanism 5 is disposed at the rear end of the feeding mechanism 4, and a discharging mechanism 6 is disposed at the rear end of the shaping mechanism 3. The feeding mechanism 4 includes an adsorption component 41 disposed at the front end of the frame 1, a supporting component 42 disposed below the adsorption component 41, and a conveying component 43. The heating mechanism 5 includes components disposed between the feeding mechanism 4 and the heating mechanism 3. The system includes a heat-conducting plate 51 between the molding mechanism 3, a transmission assembly 52 positioned above the heat-conducting plate 51, and a heating furnace 53 driven by the transmission assembly 52. ​​An adsorption assembly 41 adsorbs the thick sheet material 7 placed on the stacking plate 2. A bearing assembly 42 supports the adsorbed thick sheet material 7 and drives it backward via the transmission assembly 43. The transmission assembly 52 drives the heating furnace 53 to switch between the heat-conducting plate 51 and the molding mechanism 3 to heat the thick sheet material 7. A discharge mechanism 6 outputs the formed thick sheet material 7. This system solves the problems of uneven heating and lack of automated loading and unloading in existing thermoforming equipment, resulting in low processing efficiency.

[0038] like Figure 2 and Figure 4As shown, the adsorption assembly 41 includes a fixed plate a410 fixedly mounted on the top of the frame 1, a servo motor a411 fixedly mounted on the fixed plate a410, and a transmission rod a412 driven by the servo motor a411. Gears a413 are fixedly mounted at both ends of the transmission rod a412. A sliding sleeve a414 is provided on the fixed plate a410. A sliding rod a415 is slidably mounted inside the sliding sleeve a414. A mounting plate a416 is fixedly connected to the bottom of the sliding rod a415. A rack a417 is fixedly mounted on the top surface of the mounting plate a416. The rack a417 meshes with the gears a413. A negative pressure suction cup 418 is provided at the bottom of the mounting plate a416. A vacuum pump a419 is provided at the top of the mounting plate a416. The servo motor a411 drives the transmission rod a412 to rotate, which in turn causes the gear a413 to rotate clockwise, driving the meshing rack a417 to descend. After the rack a417 descends, it is attracted to the uppermost thick sheet material 7 by the negative pressure suction cup 418. After the negative pressure suction cup 418 attracts the thick sheet material 7, the servo motor a411 reverses, causing the gear a413 to rotate counterclockwise, driving the rack a417 to rise and lift the thick sheet material 7 to the bearing component 42. Then, the servo cylinder 422 extends and drives the mounting bracket a425, which is hinged to it, to flip inward. During the flipping process, the mounting bracket a425 supports the bottom of the thick sheet material 7 through the roller 426, so that the rotating chain a432... The needle 433 is inserted into the thick sheet 7, then the negative pressure suction cup 418 releases the thick sheet 7, and then the servo motor b430 drives the transmission rod b431 to rotate, causing the rotary chain a432 to carry the thick sheet 7 backward along the chain guide rail 434 to the heat-conducting plate 51 and then pause. Then, the heating furnace 53 and the heat-conducting plate 51 cooperate to preheat the thick sheet 7, realizing the automated feeding of the thick sheet 7. It is not necessary to manually place the thick sheet 7 one by one on the heating device, which improves the continuity of processing and saves labor costs. A hose is connected between the negative pressure suction cup 418 and the vacuum pump a419. The negative pressure suction cup 418 is an existing mature technology and will not be described in detail here.

[0039] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the transmission component 43 includes a servo motor b430 fixedly mounted at the front end of the frame 1, a transmission rod b431 driven by the servo motor b430, and a rotary chain a432 driven by the transmission rod b431. A needle 433 is fixedly mounted on the rotary chain a432. When the negative pressure suction cup 418 adsorbs the thick sheet material 7, the servo motor a411 reverses, causing the gear a413 to rotate counterclockwise, driving the rack a417 to rise and lift the thick sheet material 7 to the bearing component 42. Then, the servo cylinder 422 extends, causing the mounting bracket a425, which is hinged to it, to flip inward. During the flipping process, the mounting bracket a425 supports the bottom of the thick sheet material 7 through the roller 426, causing the pins 433 on the rotary chain a432 to penetrate the thick sheet material 7. Then, the rotary chain a432 drives the thick sheet material 7 to be transported backward. The adsorption component 41 automatically and intermittently adsorbs the thick sheet material 7 placed on the stacking plate 2, and the rotary chain a432 drives the thick sheet material 7 to move backward. After the thick sheet material 7 is shaped, the rotating chain a432 and the guide cover 435 work together to automatically detach the shaped thick sheet material 7 and drop it onto the unloading mechanism 6 below. The unloading mechanism 6 outputs the thick sheet material 7, realizing automated loading and unloading of the thick sheet material 7. This solves the problem that existing vacuum forming equipment still requires manual handling of the thick sheet material 7, which is time-consuming, labor-intensive, and affects the continuity of processing, greatly improving processing efficiency. The pins 433 set on the rotating chain a432 can drive the thick sheet material 7 to be transported stably, and when it reaches the end of the chain guide rail 434, it works with the guide cover 435 to realize the automatic detachment of the thick sheet material 7, which has strong processing continuity and saves time and labor.

[0040] like Figure 6 and Figure 7As shown, the transmission component 43 also includes a chain guide rail 434 fixedly mounted on the frame 1, with a guide cover 435 at the tail end of the chain guide rail 434. When the negative pressure suction cup 418 adsorbs the thick sheet material 7, the servo motor a411 reverses, causing the gear a413 to rotate counterclockwise, driving the rack a417 to rise and lift the thick sheet material 7 to the bearing component 42. Then, the servo cylinder 422 extends and drives the mounting bracket a425, which is hinged to it, to rotate inward. During the rotation of the mounting bracket a425, the roller 426 supports the bottom of the thick sheet material 7, causing the pins 433 on the rotating chain a432 to penetrate the thick sheet material 7. Then, the negative pressure suction cup 41... 8. Release the thick sheet material 7, then the servo motor b430 drives the transmission rod b431 to rotate, causing the rotary chain a432 to carry the thick sheet material 7 backward along the chain guide rail 434 to the heat-conducting plate 51 and then pause. At this time, the heating furnace 53 is located above the heat-conducting plate 51. Then, the heating furnace 53 and the heat-conducting plate 51 cooperate to preheat the thick sheet material 7. At the same time, the servo cylinder 422 retracts, causing the mounting bracket a425 and roller 426 to flip outward and reset. When the preheating is completed, the rotary chain a432 The conveyor continues to transport the thick sheet 7 to the thermoforming tank 310 and then pauses. After the thick sheet 7 is vacuum-formed, the rotary chain a432 continues to transport the vacuum-formed thick sheet 7 backward. When it reaches the end of the chain guide rail 434, the rotary chain a432 rotates upward, while the thick sheet 7 deflects downward under the action of the guide cover 435, thus detaching from the rotary chain a432 and falling onto the conveyor belt 66. The adsorption component 41 automatically and intermittently adsorbs the thick sheet 7 placed on the stacking plate 2. The material is adsorbed and transported backward by a rotary chain a432. After the thick sheet 7 is shaped, the rotary chain a432 and the guide cover 435 work together to make the shaped thick sheet 7 automatically fall off onto the unloading mechanism 6 below. The unloading mechanism 6 outputs the thick sheet 7, realizing the automated loading and unloading of the thick sheet 7. This solves the problem that the existing vacuum forming equipment still requires manual handling of the thick sheet 7, which is time-consuming, labor-intensive, and affects the continuity of processing.

[0041] like Figure 2 , Figure 4 and Figure 5As shown, the bearing assembly 42 includes several fixed seats 420 fixedly mounted on the top of the chain guide rail 434 and a rotating seat 421 fixedly mounted below the fixed seats 420. A servo cylinder 422 is fixedly mounted on the fixed seat 420. A rotating component 423 is hinged to the rotating seat 421. The front end of the servo cylinder 422 is hinged to the rotating component 423 through a connector 424. A mounting frame a425 is fixedly connected to the tail end of the rotating component 423. Several rollers 426 are rotatably mounted on the mounting frame a425. When the negative pressure suction cup 418 adsorbs the thick sheet material 7, the servo motor a411 reverses, causing the gear a413 to rotate counterclockwise, driving the rack a417 to rise and lift the thick sheet material 7 to the bearing component 42. Then, the servo cylinder 422 extends, causing the mounting bracket a425, which is hinged to it, to flip inward. During the flipping process, the mounting bracket a425 supports the bottom of the thick sheet material 7 through the roller 426, causing the pins 433 on the rotary chain a432 to pierce the thick sheet material 7. Then, the negative pressure suction cup 418 releases the thick sheet material 7, and the servo motor b430 drives the transmission rod b431 to rotate, causing the rotary chain a432 to carry the thick sheet material 7 backward along the chain guide rail 434 to the heat-conducting plate 51 and then pause. At this time, the heating furnace 53 is located above the heat-conducting plate 51. Then, the heating furnace 53 and the heat-conducting plate 51 cooperate to preheat the thick sheet material 7. The rotary chain a432 is equipped with a pin 433. When the adsorption component 41 adsorbs the thick sheet 7, the servo cylinder 422 in the bearing component 42 drives the mounting frame a425 to rotate inward. The roller 426 supports the bottom of the thick sheet 7. As the roller 426 follows the mounting frame a425 to rotate inward and supports the thick sheet 7, it will lift the thick sheet 7 a certain distance. After the thick sheet 7 is lifted, the pin 433 on the rotary chain a432 can be inserted into the thick sheet 7. Thus, the rotary chain a432 can drive the thick sheet 7 to be transported backward. When the rotary chain a432 drives the thick sheet 7 to the end, the thick sheet 7 is deflected downward under the action of the guide cover 435 and automatically disengages from the rotary chain a432 and falls into the unloading mechanism 6 below to complete the output. The processing is highly continuous, the degree of automation is high, and the transmission is more stable.

[0042] like Figure 8 and Figure 9As shown, the transmission assembly 52 includes guide grooves 520 fixedly disposed on both sides of the frame 1 and connecting brackets 521 slidably disposed in the guide grooves 520. A slider 522 is fixedly connected to the top of the connecting bracket 521, and rotating wheels 523 are connected to both sides of the slider 522. A rack c524 is fixedly connected to the outside of the connecting bracket 521, and the bottom of the connecting bracket 521 is fixedly connected to the heating furnace 53. After preheating is complete, the rotary chain a432 continues to transport the thick sheet 7 to the thermoplastic tank 310 and then pauses. Simultaneously, the servo motor c525 drives the transmission rod c526 to rotate, causing the gear c527 to rotate clockwise. Through the interaction of gear c527 and rack c524, the connecting bracket 521 moves to the left along the guide groove 520, thus moving the heating furnace 53 above the thermoplastic tank 310. The heating furnace 53 then heats the thick sheet 7. After heating is complete, the servo motor c525 reverses, causing the heating furnace 53 to return to its original position above the heat-conducting plate 51. The transmission assembly 52 enables the heating furnace 53 to switch between the heat-conducting plate 51 and the molding mechanism 3. When the transmission assembly 43 transports the thick sheet 7 to the heat-conducting plate 51… The thick sheet 7 is preheated by the cooperation between the heating furnace 53 and the heat-conducting plate 51. After preheating, the thick sheet 7 is shaped by the cooperation between the heating furnace 53 and the molding mechanism 3. The preheating treatment allows the surface of the thick sheet 7 to be heated more evenly during molding, avoiding uneven heating and cracking caused by direct heating of the thick sheet 7 by a single heating device. It also greatly reduces the processing time required for heating and molding, improving processing efficiency. The rotating wheel 523 is embedded in the guide groove 520 and moves, supporting the transmission component 52 and enabling the transmission component 52 to drive the heating furnace 53 to move smoothly along the guide groove 520.

[0043] like Figure 8 and Figure 9As shown, the transmission assembly 52 also includes a servo motor c525 fixedly mounted on one side of the connecting bracket 521 and a transmission rod c526 driven by the servo motor c525. Gears c527 are fixedly connected to both ends of the transmission rod c526, and the gears c527 mesh with the rack c524. The transmission component 52 drives the heating furnace 53 to switch between the heat-conducting plate 51 and the molding mechanism 3. When the transmission component 43 transfers the thick sheet to the heat-conducting plate 51, the heating furnace 53 and the heat-conducting plate 51 cooperate to preheat the thick sheet. After preheating, the thick sheet is transferred to the molding mechanism 3 by the transmission component 43. At the same time, the heating furnace 53 also moves to the molding mechanism 3 by the transmission component 52. The heating furnace 53 and the molding mechanism 3 cooperate to complete the molding of the thick sheet. The preheating treatment allows the surface of the thick sheet to be heated more evenly during molding. It avoids problems such as uneven heating of the surface of the thick sheet and cracking caused by excessively rapid heating due to direct heating by a single heating device. It also greatly reduces the processing time required for heating and molding, and improves processing efficiency.

[0044] like Figure 3 and Figure 10As shown, the molding mechanism 3 includes a thermoplastic tank 310 located at the tail end of the frame 1 and a fixed plate b311 fixedly mounted above the thermoplastic tank 310. A servo motor d312 and a transmission rod d313 driven by the servo motor d312 are fixedly mounted on the fixed plate b311. Gears d314 are fixedly mounted at both ends of the transmission rod d313. A sliding sleeve b315 is provided on the fixed plate b311. A sliding rod b316 is slidably mounted inside the sliding sleeve b315. A mounting plate b317 is fixedly connected to the bottom of the sliding rod b316. A rack d318 is fixedly mounted on the top surface of the mounting plate b317. The rack d318 meshes with the gear d314. A support frame 319 is fixedly connected to the bottom of the mounting plate b317. A pressing rod 3110 is fixedly connected to the bottom of the support frame 319. After the thick sheet material 7 is preheated, the servo motor c525 drives the transmission rod c526 to rotate, thereby causing the gear c527 to rotate clockwise. Through the cooperation of the gear c527 and the rack c524, the connecting bracket 521 moves to the left along the guide groove 520, thereby moving the heating furnace 53 above the thermoplastic tank 310. The heating furnace 53 heats the thick sheet material 7. After heating is completed, the servo motor c525 reverses, causing the heating furnace 53 to return to the position above the heat-conducting plate 51. Then, the vacuum pump b3113 performs vacuum forming on the softened thick sheet material 7, while the servo motor d3... 12 drives the transmission rod d313 to rotate, thereby causing the gear d314 to rotate clockwise and drive the rack d318 to descend. After the rack d318 descends, the pressing rod 3110 at the bottom of the support frame 319 cooperates with the cavity mold 3111 below the thermoplastic tank 310 to complete the vacuum forming of the thick sheet 7. At the same time, the fan 3112 cools the thick sheet 7. Then the pressing rod 3110 resets, and then the rotating chain a432 drives the vacuum-formed thick sheet 7 to continue to be transported backward. The good linkage between the components makes the processing process run smoothly and effectively improves the processing quality of the thick sheet 7.

[0045] like Figure 10 As shown, the molding mechanism 3 also includes a cavity mold 3111 and a blower 3112 located below the thermoforming tank 310. A vacuum pump b3113 is located on one side of the cavity mold 3111. The vacuum pump b3113 performs vacuum forming on the softened thick sheet 7. At the same time, the servo motor d312 drives the transmission rod d313 to rotate, thereby causing the gear d314 to rotate clockwise and drive the rack d318 to descend. After the rack d318 descends, the pressing rod 3110 at the bottom of the support frame 319, together with the cavity mold 3111 below the thermoforming tank 310, completes the vacuum forming of the thick sheet 7. At the same time, the blower 3112 cools the thick sheet 7. Then the pressing rod 3110 resets. The degree of automation is high. The cavity mold 3111 and the vacuum pump b3113 are connected by a hose. The vacuum forming process is an existing mature technology and will not be elaborated further here.

[0046] like Figure 11As shown, the unloading mechanism 6 includes a mounting frame b60 at the tail end of the rotary chain a432, a servo motor e61 fixedly mounted on the mounting frame b60, and a transmission rod e62 driven by the servo motor e61. Gears e63 are fixedly mounted at both ends of the transmission rod e62. A rotary chain b64 is mounted on the gears e63. A connecting plate 65 is fixedly connected to the rotary chain b64. A conveyor belt 66 is fixedly connected to the connecting plate 65. Sliding rods c67 are fixedly mounted on both sides of the mounting frame b60. Sliding sleeves c68 are mounted on both sides of the connecting plate 65 corresponding to the sliding rods c67. A servo motor f69 is mounted at the tail end of the conveyor belt 66. When the material is transferred to the end of the chain guide rail 434, the rotary chain a432 rotates upward, while the thick sheet 7 deflects downward under the action of the guide cover 435, thus disengaging from the rotary chain a432 and falling onto the conveyor belt 66. Then, the servo motor e61 drives the transmission rod e62 to rotate, causing the gear e63 to rotate clockwise. The rotation of the gear e63 drives the rotary chain b64 to rotate, causing the conveyor belt 66 to descend. Then, the servo motor f69 drives the conveyor belt 66 to rotate and output the vacuum-formed thick sheet 7. After the conveyor belt 66 completes the output, it rises and resets under the drive of the rotary chain b64. The components have good linkage, and the conveyor belt 66 can realize the automatic unloading of the vacuum-formed thick sheet 7, which solves the problem that the existing equipment still requires manual removal of the formed thick sheet 7, ensuring the personal safety of workers, greatly reducing the labor intensity of manual labor, and making the processing flow faster.

[0047] Example 2

[0048] like Figure 11 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that a pulley 610 is provided at the bottom of the mounting bracket b60. The pulley 610 allows the unloading mechanism 6 to be moved, facilitating its adjustment. The pulley 610 is equipped with a brake, ensuring stable transmission operations after the unloading mechanism 6 is adjusted.

[0049] Work process

[0050] First, the workers stack the thick sheet material 7 to be processed onto the stacking plate 2. Then, the device is turned on. Next, the servo motor a411 drives the transmission rod a412 to rotate, which in turn causes the gear a413 to rotate clockwise, driving the meshing rack a417 to descend. After the rack a417 descends, it is attracted to the top layer of thick sheet material 7 by the negative pressure suction cup 418. After the negative pressure suction cup 418 attracts the thick sheet material 7, the servo motor a411 reverses, causing the gear a413 to rotate counterclockwise, driving the rack a417 to rise and lifting the thick sheet material 7 to the bearing component 42. Then, the servo cylinder 422 extends and drives the mounting bracket a425, which is hinged to it, to flip inward. During the flipping process, the roller 426 supports the bottom of the thick sheet material 7. This causes the pins 433 on the rotary chain a432 to penetrate the thick sheet 7. Then, the negative pressure suction cup 418 releases the thick sheet 7. Next, the servo motor b430 drives the transmission rod b431 to rotate, causing the rotary chain a432 to move the thick sheet 7 backward along the chain guide rail 434 to the heat-conducting plate 51, where it pauses. At this time, the heating furnace 53 is located above the heat-conducting plate 51. The heating furnace 53 and the heat-conducting plate 51 then cooperate to preheat the thick sheet 7. Simultaneously, the servo cylinder 422 retracts, causing the mounting bracket a425 and roller 426 to flip outward and reset. After preheating is complete, the rotary chain a432 continues to move the thick sheet 7 to the thermoplastic tank 310, where it pauses. At the same time, the servo motor c525 drives the transmission rod c526 to rotate, thus causing the gears... C527 rotates clockwise, and through the engagement of gear C527 and rack C524, it drives the connecting bracket 521 to move to the left along the guide groove 520, thereby moving the heating furnace 53 above the thermoplastic tank 310. During the movement of the heating furnace 53, the negative pressure suction cup 418 picks up the next thick sheet 7 and the roller 426 causes the pin 433 on the rotary chain a432 to pierce the thick sheet 7. Then, the heating furnace 53 heats the thick sheet 7. After heating, the servo motor C525 reverses, causing the heating furnace 53 to return to above the heat-conducting plate 51. Then, the vacuum pump B3113 performs vacuum forming on the softened thick sheet 7. At the same time, the servo motor D312 drives the transmission rod D313 to rotate, thereby causing the gear D314 to rotate clockwise and drive the gear... As rack d318 descends, the pressing rod 3110 at the bottom of support frame 319, in conjunction with the cavity mold 3111 below thermoplastic tank 310, completes the vacuum forming of the thick sheet 7. Simultaneously, fan 3112 cools the thick sheet 7. Then, pressing rod 3110 resets, and rotary chain a432 drives the vacuum-formed thick sheet 7 to continue being transported backward. When it reaches the end of chain guide rail 434, rotary chain a432 rotates upward, while the thick sheet 7, under the action of guide cover 435, deflects downward, thus detaching from rotary chain a432 and falling onto conveyor belt 66. As rotary chain a432 moves the vacuum-formed thick sheet 7, it transports the next thick sheet 7 to heat-conducting plate 51 through cooperation with roller 426.This allows the heating furnace 53, in conjunction with the heat-conducting plate 51, to preheat the next thick sheet 7. Then, the servo motor e61 drives the transmission rod e62 to rotate, causing the gear e63 to rotate clockwise. The rotation of gear e63 drives the rotary chain b64 to rotate, causing the conveyor belt 66 to descend. Next, the servo motor f69 drives the conveyor belt 66 to rotate and output the vacuum-formed thick sheet 7. After outputting, the conveyor belt 66 rises and resets under the drive of the rotary chain b64. The processing operation is repeated cyclically.
