Description

Technical Field

[0001] This invention relates to the field of plastic molding technology, and in particular to an automated plastic bowl molding machine. Background Technology

[0002] In today's fast-paced lifestyle, disposable plastic products, especially disposable plastic bowls, have been widely used in many fields such as catering and food packaging due to their convenience and hygiene. Whether it's street food stalls selling various snacks or takeout food from large chain restaurants, disposable plastic bowls are ubiquitous, greatly facilitating people's lives. Existing plastic bowl production equipment typically uses blow molding. During the blow molding process, the transport of raw materials is controlled by the opening and closing of the upper and lower molds using rollers on both sides. During the mold closing process... When the two rollers stop rotating, the raw material is blow-molded. After the upper and lower molds open, the air pump vents air into the lower mold, causing the plastic bowl to be discharged and fall into the collection device. Then, the rollers on both sides rotate again to transport the raw material and blow-mold the plastic bowl again. However, the opening and closing of the upper and lower molds makes the production of plastic bowls an intermittent and continuous process, resulting in low production efficiency. In addition, multiple workers are required to collect the plastic bowls around the collection device during the production process, which not only increases the amount of manual labor but also reduces the usable area of ​​the workshop due to the addition of the collection device, thus affecting production efficiency. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the background art by proposing an automated plastic bowl forming machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automated plastic bowl forming machine includes a housing.

[0006] In the aforementioned automated plastic bowl forming machine, the side wall of the conveyor belt is provided with several evenly distributed grooves, the grooves being located outside the boss, and a circular cutter is integrally formed on the top of the bottom mold, the circular cutter being slidably inserted into the inside of the groove.

[0007] In the aforementioned automated plastic bowl forming machine, the side wall of the mold frame is integrally formed with a slide rod 2, the side wall of the housing is provided with an annular groove 1, the slide rod 2 is slidably installed inside the annular groove 1, and the annular groove 1 is provided with a slanted groove 1, a flat groove 1 and a slanted groove 2 in sequence on the upper side.

[0008] In the aforementioned automated plastic bowl forming machine, a fixed frame is provided between every two adjacent sliding columns. The fixed frame is fixedly installed inside the housing. An annular groove is provided on the side wall of the fixed frame. A sliding rod is integrally formed on the side wall of each sliding column. The sliding rod is slidably installed inside the annular groove.

[0009] In the aforementioned automated plastic bowl forming machine, the annular groove 2 is provided with an inclined groove 3, a flat groove 2, an inclined groove 4, a flat groove 3, an inclined groove 5, a flat groove 4, an inclined groove 6 and a U-shaped groove in sequence on the upper side. The U-shaped groove extends to the lower side of the annular groove 2. A V-shaped groove is provided between the U-shaped groove and the annular groove 2. The V-shaped groove is located below the inclined groove 4.

[0010] In the aforementioned automated plastic bowl forming machine, the material discharge assembly includes a sliding frame and a telescopic rod. The sliding frame is slidably installed below the second conveyor belt. The top of the sliding frame is integrally formed with two sets of support rods. The telescopic rod is slidably installed inside the support rods. The telescopic rod corresponds to the bottom mold. A second spring is provided between the bottom of the telescopic rod and the support rods. Pull ropes are fixedly connected to both sides of the sliding frame.

[0011] In the aforementioned automated plastic bowl forming machine, a raw material roller and a waste material roller are rotatably mounted at both ends of the outer side of the housing, respectively.

Through the continuous movement of conveyor belts one and two, the continuous cutting by the circular cutter, and the continuous blow molding by the air hood, the blow molding assembly continuously shapes the plastic film. The blow molding process for plastic bowls improves work efficiency. During the blow molding process, the downward movement of the slide column creates negative pressure inside the bottom mold. This negative pressure improves the uniformity of the plastic bowl wall thickness and the smoothness of the surface. After blow molding, the exhaust of the air chamber and the adsorption of the bottom mold allow the plastic bowls to be centrally discharged from the mold frame, eliminating the need for additional material collection equipment, reducing production costs, and increasing the usable area of ​​the workshop. Furthermore, the synchronous movement of the slide column and the bottom mold allows the blow molding assembly to continuously blow mold plastic bowls, further improving work efficiency.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0017] Reference Figure 1 - Figure 14 As shown, an automated plastic bowl forming machine includes a housing 1. A blow molding assembly is movably installed inside the housing 1. The blow molding assembly includes a first conveyor belt 21, an air hood 22, a second conveyor belt 31, and a mold frame 328. The first conveyor belt 21 is located above the second conveyor belt 31, and the air hood 22 is located inside the first conveyor belt 21. The bottom of the air hood 22 abuts against the inner wall of the first conveyor belt 21. The side wall of the first conveyor belt 21 is integrally formed with a plurality of evenly distributed bosses 215. The side wall of the second conveyor belt 31 is slidably installed with a plurality of evenly distributed mold frames 328. The inner wall of the mold frame 328 is provided with a plurality of evenly distributed bottom molds 32, and the bottom molds 32 correspond to the bosses 215. Each bottom mold 32 has a demolding assembly slidably installed on its bottom. The demolding assembly includes a sliding column 322 and a piston plate 325. The sliding column 322 is slidably installed on the bottom of the bottom mold 32. An air cavity 324 is opened inside the sliding column 322. The piston plate 325 is slidably installed inside the air cavity 324. Air holes 323 are opened at the bottom and top of the sliding column 322. The piston plate 325 is located between two air holes 323. A spring 326 is provided between the piston plate 325 and the bottom of the air cavity 324. A discharge assembly is movably installed at the bottom of the housing 1. The discharge assembly is used to collect and discharge the blow-molded plastic bowls.

[0018] like Figure 2 , Figure 10 , Figure 11 and Figure 13 As shown, an air pipe 221 is fixedly connected to the side wall of the air cover 22. An air hole 12 is opened on the side wall of the housing 1. The air pipe 221 is fixedly installed inside the air hole 12. The air pipe 221 is connected to an external air pump. An air hole 213 is opened on the side wall of the boss 215. An edge seal 222 is integrally formed on the side wall of the air cover 22. The thickness of the edge seal 222 is greater than the diameter of the air hole 213.

[0019] During the blow molding of the plastic bowl, conveyor belt 21 and conveyor belt 31 move the plastic film. An external air pump continuously supplies air to the inside of the air hood 22 through air pipe 221. When air hole 213 enters the inside of the air hood 22, the air hood 22 blow molds the plastic film through air hole 213. Through the continuous movement of conveyor belt 21 and conveyor belt 31 and the continuous blow molding of the air hood 22, the blow molding assembly continuously blows the plastic bowl, improving work efficiency. When air hole 213 moves out of the inside of the air hood 22, air hole 213 is located below the sealing edge 222, preventing gas leakage inside the air hood 22.

[0020] like Figure 3 , Figure 9 and Figure 13As shown, the side wall of the conveyor belt 21 has several evenly distributed grooves 214. The grooves 214 are located outside the boss 215. The top of the bottom mold 32 is integrally formed with a circular cutter 321, which is slidably inserted into the inside of the groove 214.

[0021] like Figures 9-11 As shown, the side wall of the mold frame 328 is integrally formed with a slide rod 329, and the side wall of the housing 1 is provided with an annular groove 13. The slide rod 329 is slidably installed inside the annular groove 13. The annular groove 13 is provided with a slanted groove 131, a flat groove 132 and a slanted groove 133 in sequence on the upper side.

[0022] During the movement of conveyor belt 2 31, mold frame 328 moves along with conveyor belt 2 31, causing slide bar 2 329 to slide inside annular groove 1 13. When slide bar 2 329 slides into flat groove 1 132 through inclined groove 1 131, mold frame 328 moves upward, and circular cutter 321 cuts the plastic film and slides into groove 214. At this time, bottom mold 32 abuts against conveyor belt 1 21, and boss 215 is located inside bottom mold 32. When slide bar 2 329 slides into annular groove 1 13 through inclined groove 2 133, mold frame 328 moves downward, bottom mold 32 moves away from conveyor belt 1 21, and plastic bowl blow molding is completed. The circular cutter 321 is driven by annular groove 1 13 to cut the plastic film, so that the blow molding assembly continuously blows plastic bowls, improving work efficiency.

[0023] like Figures 3-9 and Figure 12 As shown, a fixing frame 42 is provided between every two adjacent sliding columns 322. The fixing frame 42 is fixedly installed inside the housing 1. The side wall of the fixing frame 42 is provided with an annular groove 421. The side wall of the sliding column 322 is integrally formed with a sliding rod 327. The sliding rod 327 is slidably installed inside the annular groove 421. On the upper side of the annular groove 421, there are inclined grooves 422, flat grooves 423, inclined grooves 424, flat grooves 425, inclined grooves 426, flat grooves 427, inclined grooves 428 and U-shaped grooves 431. The U-shaped groove 431 extends to the lower side of the annular groove 421. A V-shaped groove 432 is provided between the U-shaped groove 431 and the annular groove 421. The V-shaped groove 432 is located below the inclined groove 424.

[0024] During the process of mold frame 328 moving with conveyor belt 31, slide column 322 moves with mold frame 328, causing slide rod 327 to slide inside annular groove 421. When slide rod 327 slides into flat groove 423 via inclined groove 422, slide column 322 moves upward, expelling air from bottom mold 32. During blow molding, after circular cutter 321 cuts the plastic film, slide rod 327 slides inside inclined groove 424, causing slide column 322 to move downward. At this time, bottom mold 32... A negative pressure is created inside the bottom mold 32. This negative pressure improves the uniformity of the plastic bowl's wall thickness and the smoothness of its surface. When the slide rod 327 slides inside the flat groove 425, as the plastic film is blown, the gas inside the bottom mold 32 enters the air chamber 324, causing the piston plate 325 to move downwards. As the bottom mold 32 moves the plastic bowl away from the air cover 22, the spring 326 drives the piston plate 325 to move upwards, and the gas inside the air chamber 324 is discharged into the bottom mold 32, causing the gas to blow upwards and move the plastic bowl. At this point, the plastic bowl is demolded. During the demolding process, slide bar 327 slides inside inclined groove 426 and flat groove 427. As the mold frame 328 moves downward, slide bar 327 slides inside inclined groove 426, causing slide column 322 and mold frame 328 to move downward synchronously. When slide bar 327 slides inside inclined groove 428, slide column 322 moves downward, creating negative pressure again between slide column 322 and the bottom of the plastic bowl. At this point, the bottom mold 32 adheres to the plastic bowl. Located inside the U-shaped groove 431, when the slide rod 327 slides into the bottom of the V-shaped groove 432, the slide column 322 touches the plastic bowl downwards, causing the plastic bowl to be discharged above the discharge assembly. Through the exhaust of the air chamber 324 and the adsorption of the bottom mold 32, the mold frame 328 discharges the plastic bowl in a concentrated manner, avoiding the need to add material receiving equipment, reducing production costs, and increasing the usable area of ​​the workshop. Furthermore, through the synchronous movement of the slide column 322 and the bottom mold 32, the blow molding assembly continuously blow molds the plastic bowl, improving work efficiency.

[0025] like Figure 1 and Figure 2 As shown, the discharge assembly includes a sliding frame 41 and a telescopic rod 413. The sliding frame 41 is slidably installed below the conveyor belt 31. Two sets of support rods 412 are integrally formed on the top of the sliding frame 41. The telescopic rod 413 is slidably installed inside the support rods 412. The telescopic rod 413 corresponds to the bottom mold 32. A spring 414 is provided between the bottom of the telescopic rod 413 and the support rods 412. Pull ropes 411 are fixedly connected to both sides of the sliding frame 41.

[0026] The bottom of the telescopic rod 413 and the bottom of the V-groove 432 are corresponding. When the slide rod 327 is at the bottom of the V-groove 432, the mold frame 328 discharges the plastic bowl. At this time, the plastic bowl falls above the telescopic rod 413. When the plastic bowl is stacked to the limit, the pull rope 411 is pulled to switch the telescopic rod 413.

[0027] like Figure 1 , Figure 2 , Figure 13 and Figure 14 As shown, a raw material roller 112 and a waste material roller 111 are rotatably mounted at both ends of the outer side of the housing 1, respectively. A plastic film is wound between the raw material roller 112 and the waste material roller 111. A pressure roller 113 is rotatably mounted inside the housing 1, and the pressure roller 113 is located above the plastic film. The plastic film is located between conveyor belt 21 and conveyor belt 31. Two rotating rollers 212 and two rotating disks 312 are rotatably mounted inside conveyor belt 21 and conveyor belt 31, respectively. A motor 211 and a motor 311 are fixedly mounted on the outer side of the housing 1. The output shafts of motor 211 and motor 311 are fixedly connected to the side wall of one of the rotating rollers 212 and the rotating disk 312, respectively.

[0028] The working principle and usage of this invention are explained in detail below: During the blow molding of the plastic bowl, conveyor belt 21 and conveyor belt 31 move the plastic film. An external air pump continuously supplies air to the inside of the air hood 22 through air pipe 221. Sliding rod 322 and mold frame 328 both move with conveyor belt 31. When sliding rod 327 slides into the inside of flat groove 423 through inclined groove 322, sliding rod 322 moves upward to expel air from the bottom mold 32. During the blow molding process, when sliding rod 329 slides into the inside of flat groove 132 through inclined groove 131... As the mold frame 328 moves upward, the circular cutter 321 cuts the plastic film, and the bottom mold 32 abuts against the conveyor belt 21. The boss 215 is located inside the bottom mold 32. At this time, the slide bar 327 slides inside the inclined groove 424, and the slide column 322 moves downward, creating a negative pressure inside the bottom mold 32. This negative pressure improves the uniformity of the plastic bowl wall thickness and the smoothness of the surface. At this time, the air hole 213 enters the air hood 22, and the air hood 22 blow-forms the plastic film through the air hole 213. Through the continuous movement of the conveyor belt 21 and the conveyor belt 21, and the air hood 212... The continuous blow molding process 2 allows the blow molding assembly to continuously blow mold the plastic bowl, improving work efficiency. As the plastic film is blown, the gas inside the bottom mold 32 enters the air chamber 324, causing the piston plate 325 to move downwards. When the slide rod 329 slides into the annular groove 13 through the inclined groove 133, the slide column 322 and the mold frame 328 move downwards synchronously, causing the bottom mold 32 to move away from the air hood 22 and the conveyor belt 21. At this time, the piston plate 325 moves upwards to expel the gas inside the air chamber 324, causing the plastic bowl to be demolded. After the plastic bowl is demolded, the slide column 322 moves downwards. The movement creates a negative pressure between the slide column 322 and the bottom of the plastic bowl. At this time, the bottom mold 32 adsorbs the plastic bowl. When the slide rod 327 slides into the bottom of the V-groove 432, the slide column 322 touches the plastic bowl downwards, causing the plastic bowl to be discharged above the discharge assembly. Through the exhaust of the air chamber 324 and the adsorption of the bottom mold 32, the mold frame 328 discharges the plastic bowls in a concentrated manner. This avoids the need to add a receiving device, reduces production costs, and increases the usable area of ​​the workshop. Furthermore, the synchronous movement of the slide column 322 and the bottom mold 32 allows the blow molding assembly to continuously blow mold the plastic bowls, improving work efficiency.

[0029] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
