Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1-4As shown, an automated thermoforming device includes a worktable 1. A lower mold platform 2 is slidably connected to one side of the worktable 1. An upper mold platform 4 is slidably connected to one side of the top of the worktable 1 via a limiting frame 3. A mold body 5 is detachably connected to the bottom of the upper mold platform 4. A first conveying roller 6 is symmetrically arranged on the top of the worktable 1 near the lower mold platform 2. A cutting blade 7 is slidably connected to the top of the worktable 1 away from the lower mold platform 2 via a fixing frame 27. A disassembly assembly is provided inside the upper mold platform 4, including a sliding plate 8. The sliding plate 8 is symmetrically slidably connected to the outside of the upper mold platform 4 via a limiting rod. Insert rods 9 are fixedly connected at equal intervals on the inner side of the sliding plate 8. Insert holes 10 that cooperate with the insert rods 9 are opened at equal intervals on both sides of the outside of the mold body 5. A vacuum tube 11 is fixedly connected to the upper inside of the upper mold platform 4. A sealing plug 12 is slidably connected to the outside of the vacuum tube 11. A connecting pipe 13 is fixedly connected to the top of the mold body 5. The upper mold platform 4 is equidistantly provided with air intake ports 20. The top of the upper mold platform 4 is symmetrically and rotatably connected with first lead screws 14. The top of each of the two first lead screws 14 is fixedly connected with a transmission gear 15, which meshes with each other. The top side of the upper mold platform 4 is fixedly connected with a first motor 16 via a mounting plate. The output end of the first motor 16 is fixedly connected with one of the transmission gears 15. The sealing plug 12 is connected to the outside of the two first lead screws 14 via a lead screw nut pair. The bottom of each of the two first lead screws 14 is fixedly connected with a first bevel gear 17. The inside of the upper mold platform 4 is rotatably connected with second lead screws 18. One end of each of the two second lead screws 18 is fixedly connected with a second bevel gear 19, which meshes with the corresponding first bevel gear 17. The other end of each of the two second lead screws 18 extends to the outside of the upper mold platform 4. The two slide plates 8 are connected to the outside of the corresponding second lead screws 18 via lead screw nut pairs.

[0020] During operation, the blister sheet is passed between the lower mold platform 2 and the upper mold platform 4. Then, both sides of the blister sheet are pushed between the two sets of first conveyor rollers 6 and second conveyor rollers 25. Starting the third motor 26 allows the blister sheet to be transported through the first conveyor rollers 6 and second conveyor rollers 25. First, the third motor 26 is paused to stop the transport of the blister sheet. Then, the second motor 22 is started, driving the third lead screw 21 to rotate. The third lead screw 21 drives the upper mold platform 4 downward through the lead screw nut pair. At the same time, the cylinder 23 is started to push the lower mold platform 2 upward until the lower mold platform 2 and the upper mold platform 4 are in contact and the blister sheet is pressed by the mold body 5. Then, the vacuum pump 24 is started, and the blister sheet is transported through the vacuum tube 11 and multiple... Each suction port 20 creates a vacuum between the vacuum-formed sheet and the mold body 5, thus achieving vacuum forming. After vacuum forming, the lower mold platform 2 and upper mold platform 4 are reset through the reverse process described above. Then, the third motor 26 continues to transport the vacuum-formed sheet. When the vacuum-formed sheet is partially transported to the side of the cutting blade 7, the electric push rod 28 is activated, which drives the cutting blade 7 to cut the formed sheet. After cutting, the sheet is automatically unloaded through the inclined surface on one side of the top of the worktable 1 and collected by an external collection device. The entire process is automated, unlike traditional manual equipment, avoiding problems such as low efficiency and large quality fluctuations caused by excessive manual intervention. It is also suitable for processing different types of materials. Upon completion, the first motor 16 is started, driving the corresponding transmission gear 15 to rotate. The meshing of the two transmission gears 15 drives the two corresponding first lead screws 14 to rotate. Since the threads of the two first lead screws 14 are opposite, the lead screw nut pair can drive the sealing plug 12 to rise and disengage from the connecting pipe 13, thus canceling the seal between the connecting pipe 13 and the vacuum tube 11. Simultaneously, the first bevel gears 17 at the bottom of the two first lead screws 14, through meshing, drive the corresponding second bevel gears 19 and second lead screws 18 to rotate. Since the threads of the two second lead screws 18 are opposite, the second lead screws 18 can drive the corresponding slide plate 8 to move outwards through the lead screw nut pair until multiple insert rods 9 are driven. After detaching from the insertion hole 10 in the mold body 5, the limiting effect on the mold body 5 is removed. The operator can then catch the mold body 5 from below to quickly disassemble it. When replacing a different mold body 5, push it upwards from below the upper mold table 4 until the connecting tube 13 at the top of the mold body 5 is in contact with the vacuum tube 11. Then, control the first motor 16 to reverse the direction. This reverses the above process and drives multiple insertion rods 9 to be inserted into the corresponding insertion hole 10, limiting the mold body 5. At the same time, the sealing plug 12 is inserted into the top of the connecting tube 13 to seal the connection between the connecting tube 13 and the vacuum tube 11, thus completing the quick installation of the replaced mold body 5.

[0021] This device allows for intermittent transmission of the thermoformed sheet by installing one end between two sets of first conveyor rollers 6 and second conveyor rollers 25. The thermoforming process is performed during the pause in transmission. After the thermoforming process is completed, the sheet is conveyed again and automatically cut by the cutting blade 7 at the rear. Then, it is automatically unloaded through the inclined surface at the top of the worktable 1. The entire process is automated, which is different from traditional manual equipment and avoids problems such as low efficiency and large quality fluctuations caused by excessive manual intervention.

[0022] Furthermore, when different types of finished products need to be processed, the corresponding mold body 5 can be disassembled and assembled through simple and quick operation. Only one person is needed to operate it quickly, avoiding the trouble of changing different production lines when processing different types of workpieces, thereby effectively improving the flexibility and adaptability of this device.

[0023] One of the limiting frames 3 is rotatably connected to a third lead screw 21 on its inner side. The upper mold platform 4 is connected to the outside of the third lead screw 21 through a lead screw nut pair. A second motor 22 is fixedly connected to the top of the limiting frame 3. The output end of the second motor 22 extends into the interior of the limiting frame 3 and is fixedly connected to the third lead screw 21. A cylinder 23 is fixedly connected to one side of the bottom of the worktable 1 through a mounting bracket. The output end of the cylinder 23 is fixedly connected to the lower mold platform 2. A vacuum pump 24 is installed on the outer side of the upper mold platform 4. One end of the vacuum tube 11 extends into the outside of the upper mold platform 4 and is fixedly connected to the vacuum pump 24. A second conveying roller 25 is rotatably connected to both sides of the top of the upper mold platform 4. A third motor 26 is fixedly connected to both sides of the top of the upper mold platform 4 near the first conveying roller 6 through a mounting block. The output end of the third motor 26 is fixedly connected to the corresponding first conveying roller 6. Electric push rods 28 are fixedly connected to both sides of the interior of the worktable 1 extending into the interior of the fixing frame 27. The output ends of the two electric push rods 28 are fixedly connected to the cutting blade 7.

[0024] Through the above technical solution, the cooperation between the second conveying roller 25 and the first conveying roller 6 can facilitate the intermittent conveying of the blister sheet, and the intermittent lifting and lowering motion of the cutting blade 7 can automatically cut the blister product, effectively realizing the automated operation of this device.

[0025] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, both sets of first conveying rollers 6 and second conveying rollers 25 are fixedly connected with anti-slip pads 29, which are made of rubber material.

[0026] During operation, the rubber anti-slip pads 29 provided on the outside of the first conveying roller 6 and the second conveying roller 25 can increase the friction between them and the blister sheet, thereby effectively improving the transmission stability of the blister sheet and avoiding slippage that could cause conveying deviation and affect the accuracy of subsequent cutting.
