Description

Technical Field

[0001] This utility model relates to the field of canned food bottle production equipment, and in particular to a stamping mechanism for preparing canned food bottles based on pressure blow molding. Background Technology

[0002] In the food packaging and storage industry, canned food jars have become indispensable packaging containers due to their excellent sealing properties, chemical stability, and reusability. The stamping mechanism, which manufactures canned food jars using pressure blow molding technology, is a core piece of equipment in the canning process, and its performance directly affects the molding quality and production efficiency. This mechanism, through the precise movement of the stamping head within the mold, shapes molten glass into the desired bottle shape, playing a crucial role in the entire production process.

[0003] Currently, most stamping mechanisms used for pressure blow molding of canned bottles on the market mainly consist of a stamping drive unit, a die holder, and a stamping head. The stamping drive unit provides power through a hydraulic or pneumatic system, driving the stamping head to reciprocate vertically. The die holder stabilizes the die, ensuring its positional accuracy during the stamping process. The stamping head, under the action of power, applies pressure to the molten glass placed inside the die, shaping it according to the shape of the die cavity's inner wall. The entire stamping process relies on mechanical transmission and die coordination to achieve automated production.

[0004] However, existing stamping mechanisms generally suffer from insufficient safety protection during operation. When the stamping head presses the molten glass in the mold, due to the high fluidity of the molten glass under high temperature and pressure, some droplets will splash out due to the impact force generated by the stamping. If these high-temperature molten glass droplets come into contact with surrounding operators, they can easily cause serious injuries such as burns. This not only threatens the personal safety of workers but also brings potential safety risks and economic losses to enterprises, becoming a key hidden danger restricting the safe and efficient operation of stamping mechanisms. Therefore, a stamping mechanism based on pressure blow molding for producing canned bottles is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stamping mechanism for preparing canned bottles based on pressure blow molding, which aims to improve the problem that some glass droplets inside the mold are easily splashed out during the stamping process of the stamping head on the inner wall of the mold, causing injury to the surrounding workers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stamping mechanism for preparing canned food bottles based on pressure blow molding includes a base plate, a fixed ring, a turntable, and a fixed frame fixedly connected to the base plate. The turntable is rotatably connected to the inner wall of the fixed ring. Multiple molds are fixedly connected to the top of the turntable. A telescopic cylinder is fixedly connected to the top of the fixed frame. A connecting column is fixedly connected to the output end of the telescopic cylinder. A stamping head is provided at the bottom of the connecting column. A blocking component is provided on the outer wall of the stamping head.

[0008] The blocking assembly includes a second baffle and a first baffle. The second baffle is fixedly connected to the outer wall of the fixed ring on one side. A plurality of sliding strips are fixedly connected to one side of the first baffle. The plurality of sliding strips are slidably connected inside the second baffle. A fixing belt is fixedly connected to the top of the first baffle. A fixing plate is fixedly connected to one side of the fixing frame. A connecting hook is fixedly connected to the bottom of the fixing plate. The connecting hook is in contact with the inner wall of the fixing belt.

[0009] As a further description of the above technical solution:

[0010] Each of the slide bars is fixedly connected to one end with a limiting ring, and the multiple limiting rings are in contact with one side of the baffle. The outer wall of the stamping head is provided with a replacement component.

[0011] As a further description of the above technical solution:

[0012] The replacement component includes multiple trapezoidal blocks I, trapezoidal blocks II, and a clamping plate. A connecting ring II is fixedly connected to the top of the stamping head, and a connecting ring I is fixedly connected to the bottom of the connecting column. The connecting ring I and the connecting ring II are in close contact.

[0013] As a further description of the above technical solution:

[0014] The connecting ring 2 has multiple springs 1 inside, and each spring 1 has a connecting cylinder 1 fixedly connected to one end, and the other end of the multiple connecting cylinders 1 is fixedly connected to a connecting disc.

[0015] As a further description of the above technical solution:

[0016] Each of the connecting discs has a push ring fixedly connected to one end, and a transmission column fixedly connected to the top of each connecting disc.

[0017] As a further description of the above technical solution:

[0018] Each of the transmission columns has a connecting cylinder 2 and a trapezoidal block 1 slidably connected to its outer wall, and the top of each connecting cylinder 2 is fixedly connected to the bottom of the trapezoidal block 1.

[0019] As a further description of the above technical solution:

[0020] Each of the transmission columns is fixedly connected to a trapezoidal block II at its top, and each of the trapezoidal blocks II has a retaining plate on both sides of its bottom. Multiple retaining plates are slidably connected inside the connecting ring I.

[0021] As a further description of the above technical solution:

[0022] The connecting ring 1 has multiple springs 2 inside. One end of each spring 2 is fixedly connected to one side of the card plate, and the other end of each spring 2 is fixedly connected to a rubber pad. One side of each rubber pad is fixedly connected to the inside of the connecting ring 1.

[0023] This utility model has the following beneficial effects:

[0024] In this invention, the position of baffle one is adjusted by sliding the limiting ring on the inner wall of baffle two. Then, the position of baffle one is fixed by the connecting hook fitting against the inner wall of the fixing belt. Baffle one and baffle two block one side of the punch head, thus protecting the punch head during the punching process on the inner wall of the mold. This solves the problem that some glass droplets inside the mold are easy to splash out and cause injury to surrounding workers during the punching process, and enhances the safety of the equipment during use.

[0025] In this invention, the replacement of the punch head is achieved by engaging the card plate with the bottom plane of the trapezoidal block II. This solves the problem that when replacing the punch head, it is usually necessary to use a special tool to unscrew the bolts on the surface, which can easily lead to a long time consumption. This improves the replacement efficiency of the punch head. Attached Figure Description

[0034] Reference Figures 1-3 This utility model provides an embodiment of a stamping mechanism for producing canned bottles based on pressure blow molding, comprising a base plate 1, a fixed ring 2, a turntable 3, and a fixed frame 5 fixedly connected to the base plate 1. The fixed ring 2 supports the turntable 3 and limits its rotation range, enabling the turntable 3 to rotate stably and accurately position the mold 4. The turntable 3 is rotatably connected to the inner wall of the fixed ring 2. The turntable 3 carries multiple molds 4 and enables station switching, improving stamping efficiency. Multiple molds 4 are fixedly connected to the top of the turntable 3. The molds 4 are used to accommodate glass raw materials and form a stamping cavity, which works with the stamping head 8 to complete the forming of glass products. The top of the fixed frame 5 is fixedly connected to the mold. A telescopic cylinder 6 is fixedly connected to the mold 4. The fixed frame 5 is used to fix the telescopic cylinder 6 and provide stable support to ensure the vertical movement accuracy of the connecting column 7 and the punch head 8. The output end of the telescopic cylinder 6 is fixedly connected to the connecting column 7. The telescopic cylinder 6 is used to drive the connecting column 7 and the punch head 8 to move up and down reciprocally, providing the power required for punching. The bottom of the connecting column 7 is provided with the punch head 8. The connecting column 7 is used to connect the telescopic cylinder 6 and the punch head 8, transmit the punching force, and realize the replacement function of the punch head 8. The outer wall of the punch head 8 is provided with a blocking component. The punch head 8 is used to apply pressure to the glass raw material in the mold 4 to complete the stamping process.

[0035] The blocking assembly includes a second baffle 15 and a first baffle 12. The second baffle 15 is fixedly connected to the outer wall of the fixing ring 2 on one side. The second baffle 15 works in conjunction with the first baffle 12 to form a protective barrier, blocking splashing glass droplets. Multiple sliding strips 13 are fixedly connected to one side of the first baffle 12. These sliding strips 13 are slidably connected inside the second baffle 15, allowing for sliding along the inner wall of the second baffle 15 to adjust the height of the first baffle 12. A fixing strap 11 is fixedly connected to the top of the first baffle 12. The fixing strap 11 works in conjunction with the connecting hook 10 to fix the position of the first baffle 12, ensuring protection. For stability, a fixing plate 9 is fixedly connected to one side of the fixing frame 5. The fixing plate 9 is used to support the connecting hook 10 and keep its position fixed. The bottom of the fixing plate 9 is fixedly connected to the connecting hook 10. The connecting hook 10 is used to hook the fixing strap 11 to realize the quick fixation of the baffle 12. The connecting hook 10 is in contact with the inner wall of the fixing strap 11. Each slide bar 13 is fixedly connected to one end with a limit ring 14. The limit ring 14 is used to limit the movement range of the slide bar 13 and prevent it from falling off the baffle 2 15. Multiple limit rings 14 are in contact with one side of the baffle 2 15. A replacement component is provided on the outer wall of the stamping head 8.

[0036] Reference Figure 4 and Figure 5The replacement components include multiple trapezoidal blocks 24, 25, and a clamping plate 26. Trapezoidal blocks 24 and 25 are used to compress and release the clamping plate 26 via inclined surfaces, enabling quick assembly and disassembly of the punch head 8. A connecting ring 17 is fixedly connected to the top of the punch head 8, and this connecting ring 17 mates with connecting ring 16 to form a connection interface for the punch head 8. A connecting ring 16 is fixedly connected to the bottom of the connecting post 7. Connecting ring 16 accommodates trapezoidal blocks 24 and 25 and provides installation space for the clamping plate 26. Connecting ring 16 and connecting ring 17 are fitted together. 17 contains multiple springs 21, which provide a restoring force to move the transmission column 22 and trapezoidal block 25. Each spring 21 has a connecting cylinder 20 fixedly connected to one end, which transmits the spring force and moves the connecting plate 19. The other ends of the connecting cylinders 20 are fixedly connected to connecting plates 19, which connect the transmission columns 22 and enable synchronous movement. Each connecting plate 19 has a push ring 18 fixedly connected to one end, which is used for manual operation to trigger the unlocking action for component replacement. Each connecting plate 19 has a fixed connection at its top. A transmission column 22 is connected to the stamping head 8. The transmission column 22 is used to transmit the driving force and drive the trapezoidal block 1 24 and trapezoidal block 25 to move. The outer wall of each transmission column 22 is slidably connected to the connecting cylinder 23 and the trapezoidal block 1 24. The connecting cylinder 23 is used to connect the trapezoidal block 1 24 and the transmission column 22 to achieve linkage. The top of each connecting cylinder 23 is fixedly connected to the bottom of the trapezoidal block 1 24. The top of each transmission column 22 is fixedly connected to the trapezoidal block 25. Each trapezoidal block 25 has a locking plate 26 on both sides of its bottom. The locking plate 26 is used to lock the trapezoidal block 25 by the elastic force of the spring 27, thereby fixing the stamping head 8. A locking plate 26 is slidably connected inside the connecting ring 16. Multiple springs 27 are provided inside the connecting ring 16. Springs 27 are used to provide the reset elastic force of the locking plate 26 to ensure locking stability. One end of each spring 27 is fixedly connected to one side of the locking plate 26, and the other end of each spring 27 is fixedly connected to a rubber pad 28. The rubber pad 28 is used to buffer the impact force of the spring 27 and reduce noise. Multiple rubber pads 28 are fixedly connected to the inside of the connecting ring 16 on one side. The bottom of the locking plate 26 is provided with an inclined surface that matches the inclined surface of the trapezoidal block 24. The angle between the inclined surface and the horizontal direction is 60°.

[0037] Working principle: During the protection process of the stamping process, the baffle 12 is pulled upward to move the slide bar 13 on the inner wall of the baffle 2 15. The movement direction of the slide bar 13 is limited by the limiting ring 14 and the baffle 12 to prevent it from separating from the inner wall of the baffle 2 15. Next, the connecting hook 10 is hung on the inner wall of the fixing belt 11 to fix the position of the baffle 12. The baffle 12 and the baffle 2 15 protect the stamping head 8 from the stamping process on the inner wall of the mold 4. This solves the problem that some glass droplets inside the mold 4 are easy to splash out and cause injury to the surrounding workers during the stamping process of the stamping head 8 on the inner wall of the mold 4, thus enhancing the safety of the equipment during use.

[0038] During the replacement of the stamping head 8, the push ring 18 is moved upwards, causing the connecting cylinder 20, transmission column 22, and connecting cylinder 23 to also move upwards. As the connecting cylinder 20 moves, it compresses the spring 21. Simultaneously, the movement of the transmission column 22 and connecting cylinder 23 causes the trapezoidal block 25 and trapezoidal block 24 to move as well. The trapezoidal blocks 25 and 24 have symmetrically distributed inclined surfaces on both sides, with an angle of 60 degrees between the inclined surfaces and the opposing surfaces of trapezoidal blocks 24 and 25. Since the connecting cylinder 23 is slidably connected to the outer wall of the transmission column 22, the bottom of the connecting cylinder 23 adheres to the top of the connecting plate 19 due to gravity. Therefore, as the connecting plate 19 moves, it also causes the trapezoidal block 25 at one end of the transmission column 22 to move. The trapezoidal blocks 24 at one end of the connecting cylinder 23 move synchronously. When the trapezoidal blocks 24 pass the surfaces of the two side plates 26, the top of the trapezoidal blocks 24 pushes the inclined surfaces at the bottom of the two side plates 26 to move. At this time, the trapezoidal blocks 24 and the plates 26 are connected by a line. The moving force of the trapezoidal blocks 24 will cause the plates 26 to move in the opposite direction inside the connecting ring 17, thereby pushing the spring 27 to compress. When the trapezoidal blocks 24 have completely moved to the top of the plates 26, the pressing force on the pushing ring 18 is released. At this time, the pushing ring 18 loses the pushing force on the connecting cylinder 20 at one end of the connecting plate 19, causing the spring 21 to no longer be compressed, resulting in a rebound. The rebound force of the spring 21 will be transmitted through the connecting plate 19 at one end of the connecting cylinder 20 to... The downward movement causes the trapezoidal block 25 at one end of the transmission column 22 to move. At this time, the trapezoidal block 24 is supported by the top of the clamping plate 26, keeping its position fixed. When one side of the plane of the trapezoidal block 25 coincides with one side of the plane of the trapezoidal block 24, the rebound force of the spring 21 continues to push the trapezoidal block 25 to move. The inclined surfaces on both sides of the trapezoidal block 25 and the trapezoidal block 24 press against the clamping plate 26. Since the bottom plane of the trapezoidal block 25 coincides with the top plane of the trapezoidal block 24, the clamping plate 26 cannot block the bottom plane of the trapezoidal block 25. In this way, the trapezoidal blocks 24 and 25 can be smoothly moved out of the connecting ring 16, achieving the effect of separating the stamping head 8 from the connecting column 7. Then, the other... One stamping head 8 moves to its original position. Following the same principle, the symmetrical inclined surfaces on both sides of trapezoidal block 25 push the two clamping plates 26 to move in the opposite direction, compressing spring 27. When the bottom plane of trapezoidal block 25 is completely moved to the top of clamping plate 26, clamping plate 26 loses the squeezing force of trapezoidal block 25. The rebound force of spring 27 pushes the top plane of clamping plate 26 to fit against the bottom plane of trapezoidal block 25, thus blocking and limiting the bottom position of trapezoidal block 25. Because there is a certain distance between trapezoidal block 25 and trapezoidal block 24, clamping plate 26 can smoothly fit against the bottom of trapezoidal block 25. Simultaneously, connecting ring 16 blocks and fixes the top position of connecting ring 17 on the outer wall of stamping head 8.This ultimately achieves the installation and fixation between the stamping head 8 and the connecting post 7, enabling the replacement of the stamping head 8. It solves the problem that replacing the stamping head 8 typically requires using specific tools to unscrew the surface bolts, which is time-consuming, thus improving the replacement efficiency of the stamping head 8.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
