Description

Technical Field

[0001] The invention relates to the technical field of plastic molding, in particular to a full-automatic vacuum molding machine and method for processing packaging boxes. Background Art

[0002] In the packaging box processing industry, traditional manual or semi-automatic forming equipment can no longer meet the high efficiency, high precision and high quality requirements of modern industrial production. With the advancement of science and technology and the development of the manufacturing industry, fully automatic vacuum forming machines have emerged and gradually become the mainstream equipment in the packaging box processing field. Traditional packaging box processing methods usually involve multiple cumbersome steps, including material cutting, forming, trimming and packaging. These steps often rely on manual operation, which is not only inefficient, but also difficult to ensure product consistency and quality. In addition, manual operation also poses safety hazards, increasing production costs and management difficulties.

[0003] For example, the patent application with the prior art announcement number CN219153706U is designed in the field of vacuum forming machines, and discloses a vacuum forming machine for blister packaging boxes. In this application, it includes a mounting box, a mounting frame is fixedly installed on one side of the outer wall of the mounting box, a fixing frame is fixedly installed on the side of the mounting frame away from the mounting box, a hydraulic press is fixedly installed on the side of the fixing frame away from the mounting frame, a hydraulic rod is arranged on one side of the inner wall of the hydraulic press, a vacuum pump is fixedly installed on the end of the hydraulic rod away from the hydraulic press, a fixing ring is fixedly installed on the side of the vacuum pump close to the suction head, a motor is fixedly installed on one side of the inner wall of the mounting box, a transmission rod is fixedly installed on the output end of the motor, a turntable is fixedly installed on the side of the transmission rod away from the motor, a mold is placed on the side of the turntable close to the vacuum pump, and the vacuum pump vacuum forms the material in the mold. After forming, the turntable is rotated to replace a new mold, thereby making mold replacement more convenient.

[0004] In the above-mentioned fully automatic vacuum forming machine for packaging box processing of the prior art, although the rapid replacement of the mold is achieved by setting a turntable, thereby significantly improving the production efficiency, in the actual operation process, especially after vacuum forming, the material tends to adhere tightly to the mold surface, which brings considerable difficulties to the removal of the formed material. Specifically, when the material is tightly adsorbed and formed on the mold in a vacuum environment, due to the vacuum suction force and the viscosity of the material itself, a layer of adhesion that is difficult to peel off will be formed between the formed material and the mold. This not only increases the difficulty of removing the molded material, but may also cause the material to be deformed or damaged during the removal process, thereby affecting the quality and consistency of the product. To this end, the present application proposes a fully automatic vacuum forming machine and method for packaging box processing. Summary of the invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The forming plate is driven by the cylinder to move, so that the forming mold can accurately enter the inside of the forming die groove for forming. The whole process is highly automated, which greatly improves production efficiency. Through the cooperation of the insert cylinder and the connecting groove, as well as the ingenious design of the hollow rotating cylinder, air cavity and driving components (air receiving cylinder, driven piston rod, etc.), the function of automatically adjusting the position of the shovel block during the forming process is realized. When the forming mold is close to the forming die groove, the shovel block moves up to provide forming space; after the forming is completed, the shovel block moves down to shovel the material attached to the surface of the forming mold.

[0024] 2. By setting the air pump and the air jet hole, after the forming mold is separated from the forming mold groove, the gas can be transported into the forming mold groove, effectively cleaning the debris and residual materials attached to the inner wall, avoiding the tediousness and safety hazards of manual cleaning. The matching design of the arc block and the sealing plate ensures that when the forming mold is fitted with the forming mold groove, the air jet hole is automatically closed, preventing gas leakage and interference with the forming process. The design of the collision between the driven gear rod and the rotating ring, and the rotation of the active gear rod in the expansion strip realize the automatic control of the matching process between the insert and the connecting groove. When the insert is inserted into the connecting groove, the rotation of the straight plate drives the connecting rod and the driven gear rod to move, and then drives the rotating ring to move and rotate, automatically closing the air jet hole. The design of the turbine blade and the rotating rod enables the gas transported to the air cavity in the connecting groove to drive the turbine blade to rotate, and then drive the connection air-blocking shell to rotate and the expansion strip to expand. This design not only makes full use of the energy of the gas, but also realizes the secondary use of the gas, improving the energy utilization efficiency. At the same time, the matching design of the connecting air-blocking shell and the air-blocking ring ensures the orderly flow and distribution of the gas, avoiding gas leakage and waste. The design of the rotating ring, the friction ring and the straight rubber not only enhances the structural stability of the equipment, but also improves the wear resistance and durability between the components. This design enables the equipment to maintain good performance and accuracy during long-term use. The setting of the tension spring also ensures that the sealing plate is reset in time after the rotating ring moves, ensuring the normal opening and closing of the air injection hole.

The feed pipes 213 can divert the material and evenly enter the inside of the forming die groove 208. The vacuum frame 100 Slide racks 206 are fixedly connected on both sides of the vacuum rack 100, and protective plates 203 are arranged on both sides of the vacuum rack 100. Slide shoes 207 slidably connected to the slide racks 206 are fixedly connected inside the protective plates 203. Guide rods 211 for sliding connection of the forming plate 200 are fixedly connected inside the vacuum rack 100. The guide rods 211 can provide stable support for the sliding of the forming plate 200, and the protective plates 203 are fixedly connected to both sides of the forming plate 200 and move with the movement of the forming plate 200, thereby providing a barrier between the vacuum rack 100 and the forming plate 200 when working.

[0045] For further information, see Fig.10 , Fig.11 as well as Fig.12The interior of the insert cylinder 300 is rotatably connected to a hollow rotating cylinder 301, and a straight plate 302 is fixedly connected to the outer surface of one end of the hollow rotating cylinder 301, and balls 303 are rotatably connected to both ends of the straight plate 302. An air cavity 307 is opened inside the insert cylinder 300, and a shovel block 500 for unloading is provided on the outer surface of the insert cylinder 300. The interior of the air cavity 307 is configured with a driving component for adjusting the position of the shovel block 500. The interior of the connecting groove 400 is configured with a guide groove 402 adapted to the ball 303. The interior of the connecting groove 400 is fixedly connected to a piston rod 404 adapted to the hollow rotating cylinder 301. By arranging the cooperation between the hollow rotating cylinder 301 and the piston rod 404, the gas in the hollow rotating cylinder 301 can be expanded, so that the gas in the hollow rotating cylinder 301 is transported to the inside of the air cavity 307, thereby realizing the gas transportation and effectively operating the driving component.

[0046] Among them, see Fig.10 , Fig.11 as well as Fig.13 The driving assembly includes an air receiving cylinder 502 fixedly connected to the outer surface of the insert cylinder 300 and connected to the air cavity 307, and one end of the air receiving cylinder 502 is slidably connected to a slave piston rod 503 adapted thereto, the outer surface of the insert cylinder 300 is rotatably connected to a connecting rod 501 fixedly connected to the shovel block 500, and one end of the slave piston rod 503 away from its piston end is slidably connected to the bottom of the connecting rod 501, and the outer surface of the slave piston rod 503 is sleeved with a spring 504 for its own reset, and the interior of the insert cylinder 300 is provided with a plurality of air connecting grooves 306 connected to the air cavity 307, and the outer surface of the hollow rotating cylinder 301 is provided with a plurality of air grooves 305 adapted to the air connecting grooves 306, wherein the expansion of gas in the air cavity 307 can effectively push the slave piston rod 503 to move, so that the slave piston rod 503 pushes the shovel block 500 to move upward.

[0047] Specifically, when in use, the cylinder 205 is driven to move the forming plate 200, so that the forming mold 209 enters the inside of the forming mold groove 208. At the same time, when the forming mold 209 is close to the forming mold groove 208, its multiple insert cylinders 300 will gradually insert into the inside of the connecting groove 400. At this time, the ball 303 will enter the inside of the guide groove 402 to rotate the straight plate 302. At the same time, the piston rod 404 enters the inside of the hollow rotating cylinder 301 to squeeze the gas in the hollow rotating cylinder 301. At the same time, the rotation of the straight plate 302 will continuously displace and overlap the multiple gas grooves 305 with the connecting gas grooves 306. When the gas grooves 305 overlap with the connecting gas grooves 306, the hollow The gas in the rotating drum 301 is transported to the inside of the air cavity 307. At this time, the gas in the air cavity 307 expands and is transported to the inside of the air receiving cylinder 502, pushing the driven piston rod 503 to move upward, thereby driving the shoveling block 500 to move upward, thereby providing a molding space. When the molding is completed, the molding mold 209 is separated from the molding mold groove 208, so that the insert cylinder 300 is separated from the connecting groove 400. At this time, the hollow rotating drum 301 inhales gas from the air cavity 307 and drives the shoveling block 500 to move downward, so that the shoveling block 500 shovels away the material that is attached to and adsorbed on the surface of the molding mold 209, thereby realizing material unloading. At the same time, the bottom of the vacuum frame 100 is hollow for the material on the molding mold 209 to be separated from the bottom.

[0048] In summary, the molding plate 200 is driven to move by the cylinder 205, so that the molding mold 209 can accurately enter the molding die groove 208 for molding. The whole process has a high degree of automation, which greatly improves the production efficiency. Through the cooperation of the insert cylinder 300 and the connecting groove 400, as well as the ingenious design of the hollow rotating cylinder 301, the air cavity 307, the driving component air cylinder 502, the driven piston rod 503, etc., the function of automatically adjusting the position of the shovel block 500 during the molding process is realized. When the molding mold 209 is close to the molding die groove 208, the shovel block 500 moves up to provide molding space; after the molding is completed, the shovel block 500 moves down to shovel the material attached to the surface of the molding mold 209. The barrel 212 is connected to the molding die groove 208 through multiple conveying pipes 213, and the material can be evenly distributed to the inside of the molding die groove 208, avoiding material waste. The auxiliary frame 101, the top frame 102, the protective plate 203 and the sliding shoe 207 and other components provide all-round safety protection to prevent accidental injuries during the production process.

[0049] Example 2: Please refer to Figure 8 , Fig. 9 as well as Fig.10The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a fully automatic vacuum forming machine for packaging box processing, a plurality of air pumps 401 are fixedly connected to one side of the vacuum frame 100, and the air delivery end of the air pump 401 extends to the inside of the connecting groove 400, and a swivel 403 is slidably connected to the inside of the connecting groove 400, and a cleaning component is provided at one end of the swivel 403, a connecting rod 310 is rotatably connected to the inside of the straight plate 302, and an active gear rod 311 is fixedly connected to one end of the connecting rod 310, and the active gear rod 311 is adapted to a plurality of expansion strips 309, and the other end of the connecting rod 310 passes through the straight plate 302 and is fixedly connected to a driven gear rod 304, and the driven gear rod 304 conflicts with the swivel 403.

[0050] Furthermore, the cleaning assembly includes a plurality of air jet holes 405 opened inside the vacuum frame 100 and connected to the molding die groove 208, a sealing plate 406 adapted to the plurality of air jet holes 405 is arranged inside the vacuum frame 100, a tension spring 407 fixedly connected to the sealing plate 406 is fixedly connected inside the vacuum frame 100, an arc block 408 abutting against the sealing plate 406 is fixedly connected to one end of the rotating ring 403, a resisting ring 409 is fixedly connected to one end of the rotating ring 403, and the resisting ring A plurality of straight rubber strips 410 are fixedly connected to the interior of 409, and the plurality of straight rubber strips 410 are adapted to the driven gear rod 304. By setting up an air pump 401, gas can be continuously transported into the forming groove 208 to clean up the debris on its inner wall. When the forming groove 208 is fitted with the forming mold 209, the arc block 408 will push the sealing plate 406 downward to block the plurality of injection holes 405, so that the gas generated by the air pump 401 cannot pass through the injection holes 405 and enter the interior of the forming groove 208.

[0051] Among them, see Fig.11 , Fig.14 as well as Fig.15 The interior of the insert tube 300 is connected to a ventilation chamber 308 connected to the air cavity 307, and a plurality of expansion strips 309 connected to the ventilation chamber 308 are fixedly connected to the interior of the insert tube 300. The interior of the ventilation chamber 308 is rotatably connected to a rotating rod 312, and a turbine blade 317 is fixedly connected to the outer surface of the rotating rod 312. A plurality of connecting air blocking shells 315 are fixedly connected to the outer surface of the connecting air blocking shells 315, and a plurality of air leakage holes 316 are provided on the outer surfaces of the plurality of connecting air blocking shells 315. A plurality of air blocking rings 313 are fixedly connected to the interior of the ventilation chamber 308, and a plurality of ventilation grooves 314 are provided inside the air blocking rings 313.

[0052] Specifically, when the gas in the connecting groove 306 is transported to the air cavity 307, the turbine blade 317 will be driven to rotate and the rotating rod 312 will be driven to rotate, so that the rotating rod 312 drives the multiple connected air blocking shells 315 to rotate so that the air leakage hole 316 and the ventilation groove 314 gradually overlap, so that the gas is transported to the inside of the ventilation chamber 308. When the gas increases, the expansion bar 309 will expand. When the straight plate 302 rotates, it drives the connecting rod 310 to make a circular motion, so that the active gear rod 311 rotates in the expansion bar 309 and drives the connecting rod 310 to rotate, thereby driving the driven gear rod 304 to rotate, so that the driven gear rod 304 conflicts with the conflict ring 409 and pushes the rotating ring 403 to move, and at the same time, The movable gear rod 304 follows the straight plate 302 to make a circular motion while rotating, so that the driven gear rod 304 drives the rotating ring 403 to rotate and drives the arc block 408 to move downward, thereby resisting the sealing plate 406 from moving downward and closing the air injection hole 405. At this time, the molding die 209 and the molding die groove 208 are completely closed, and at the same time, the gas generated by the air pump 401 cannot enter the interior of the molding die groove 208 through the air injection hole 405. Subsequently, the molding die 209 is driven to reset away from the molding die groove 208, and the driving rotating ring 403 is rotated and reset, so that the sealing plate 406 moves upward under the action of the tension spring 407, so that the gas generated by the air pump 401 is poured into the interior of the molding die groove 208 to clean its inner wall.

[0053] In summary, by providing the air pump 401 and the air jet hole 405, gas can be transported into the molding cavity 208 after the molding mold 209 is separated from the molding cavity 208, thereby effectively cleaning the debris and residual materials attached to the inner wall thereof, thereby avoiding the tediousness and safety hazards of manual cleaning. The coordinated design of the arc block 408 and the sealing plate 406 ensures that when the molding mold 209 is fitted with the molding cavity 208, the air jet hole 405 is automatically closed, thereby preventing gas leakage and interference with the molding process. The interference design between the driven gear rod 304 and the swivel 403, as well as the rotation of the active gear rod 311 in the expansion strip 309, realizes the automatic control during the coordination process between the insert 300 and the connecting groove 400. When the insert 300 is inserted into the connecting groove 400, the rotation of the straight plate 302 drives the connecting rod 310 and the driven gear rod 304 to move, thereby driving the swivel 403 to move and rotate, automatically closing the jet hole 405, and the design of the turbine blade 317 and the rotating rod 312 enables the gas transported to the air cavity 307 in the connecting groove 306 to drive the turbine blade 317 to rotate, thereby driving the connecting air blocking shell 315 to rotate and the expansion strip 309 to expand. This design not only makes full use of the energy of the gas, but also realizes the secondary utilization of the gas, thereby improving the energy utilization efficiency. At the same time, the matching design of the connecting air blocking shell 315 and the air blocking ring 313 ensures the orderly flow and distribution of the gas, and avoids gas leakage and waste. The design of components such as the swivel 403, the abutment ring 409 and the straight rubber strip 410 not only enhances the structural stability of the equipment, but also improves the wear resistance and durability between the components. This design enables the device to maintain good performance and accuracy during long-term use. The provision of the tension spring 407 also ensures that the sealing plate 406 is reset in time after the rotating ring 403 moves, thereby ensuring the normal opening and closing of the air injection hole 405.

[0054] Example 3: Please refer to Figures 1 to 15 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a fully automatic vacuum forming method for packaging box processing, comprising the following steps:

[0055] S1. When in use, the cylinder 205 is driven to move the forming plate 200, so that the forming mold 209 enters the inside of the forming mold groove 208. At the same time, when the forming mold 209 is close to the forming mold groove 208, its multiple insert cylinders 300 will gradually insert into the inside of the connecting groove 400. At this time, the ball 303 will enter the inside of the guide groove 402 to rotate the straight plate 302. At the same time, the piston rod 404 enters the inside of the hollow rotating cylinder 301 to squeeze the gas in the hollow rotating cylinder 301. At the same time, the rotation of the straight plate 302 will continuously displace and overlap the multiple gas grooves 305 with the connecting gas grooves 306. When the gas grooves 305 overlap with the connecting gas grooves 306, the gas in the hollow rotating cylinder 301 will be transported to the inside of the air cavity 307. At this time, the gas in the air cavity 307 will expand and be transported to the inside of the gas receiving cylinder 502, pushing the driven piston rod 503 to move up, driving the shovel block 500 to move up, and providing a forming space;

[0056] S2, when the gas in the connecting gas groove 306 is transported to the gas cavity 307, the turbine blade 317 will be driven to rotate, and the rotating rod 312 will be driven to rotate, so that the rotating rod 312 drives the multiple connecting gas blocking shells 315 to rotate so that the gas leakage hole 316 and the ventilation groove 314 gradually overlap, so that the gas is transported to the inside of the ventilation chamber 308, and when the gas increases, the expansion strip 309 will expand;

[0057] S3, when the straight plate 302 rotates, the connecting rod 310 is driven to make a circular motion, so that the active gear rod 311 rotates in the expansion strip 309 and drives the connecting rod 310 to rotate, thereby driving the driven gear rod 304 to rotate, so that the driven gear rod 304 conflicts with the abutment ring 409 and pushes the rotating ring 403 to move, and at the same time, the driven gear rod 304 follows the straight plate 302 to make a circular motion while rotating itself, so that the driven gear rod 304 drives the rotating ring 403 to rotate and drives the arc block 408 to move downward and abut the sealing plate 406 to move downward and close the air injection hole 405. At this time, the molding die 209 and the molding die groove 208 are completely closed, and at the same time, the gas generated by the air pump 401 cannot enter the interior of the molding die groove 208 through the air injection hole 405;

[0058] S4. The material in the barrel 212 is transported to the multiple material delivery pipes 213 through the diverter valve by using a vacuum pump, so that the multiple material delivery pipes 213 fill the material into the interior of the molding cavity 208. Then, the air collecting pipe 201 is controlled to generate negative pressure so that the multiple molding molds 209 generate suction so that the suction holes 214 inhale air, thereby adsorbing the material to form it. Then, the molding mold 209 is driven to reset away from the molding cavity 208, and the driving rotating ring 403 is driven to rotate and reset, so that the sealing plate 406 moves upward under the action of the tension spring 407, so that the gas generated by the air pump 401 is poured into the interior of the molding cavity 208 to clean its inner wall. At the same time, the piston rod 404 draws away the gas in the hollow rotating cylinder 301 and drives the gas in the air cavity 307 to flow back to the interior of the hollow rotating cylinder 301, so that the rotating ring 403 is reset and drives the shovel block 500 to move downward, so that the shovel block 500 shovels away the material adsorbed on the surface of the molding mold 209 to achieve material unloading.
