Abstract
Description
Technical Field
[0001] This invention relates to the field of balloon molding technology, and in particular to a balloon blow molding machine. Background Technology
[0002] A balloon blow molding machine is a specialized piece of equipment used to produce balloon-like products such as medical balloons. Its core principle is to use a blow molding process to form hollow balloons with specific shapes and functions from plastic granules or sheet materials.
[0003] The invention disclosed in CN222061182U relates to a balloon forming machine. A clamping cylinder holds one side of a conduit, while the other side passes through a mold cavity and is held by a pneumatic clamp. After both ends of the conduit are stably clamped, a heating block heats the conduit in a specific area. After the conduit is heated, a first guide rail drives a first moving stage along with the pneumatic clamp, and a second guide rail drives a fourth moving stage along with the clamping cylinder, all moving in opposite directions simultaneously. When the conduit moves a certain distance in the opposite direction, the heated portion is stretched to the required thickness. Simultaneously, the clamping cylinder delivers inert gas into the conduit through an outlet, causing the inert gas to expand the heated inner wall of the conduit, thus pressing the outer wall of the conduit tightly against the inner wall of the mold cavity, ultimately forming a balloon.
[0004] However, the aforementioned balloon blow molding machine does not have the function of detecting the balloon diameter. During use, the balloons formed on the tubing need to be cut off manually and then checked by passing them through the go / no-go gauges one by one. Each formed balloon needs to be inspected manually and the tubing needs to be clamped, which causes inconvenience to the production and inspection of balloons, resulting in low production efficiency. Summary of the Invention
[0005] To facilitate the production and inspection of balloons, this application provides a balloon blow molding machine.
[0006] The balloon blow molding machine provided in this application adopts the following technical solution:
[0007] A balloon blow molding machine includes a worktable, a blanking inspection mechanism for inspecting finished products, and a drive mechanism. The worktable has an upper mold and a lower mold. The lower mold is rotatably connected to the worktable. The blanking inspection mechanism includes two sets of blades, a go gauge, and a no-go gauge. The two sets of blades are movably connected to both sides of the lower mold. The no-go gauge is fixedly connected to the worktable. The go gauge is slidably connected to the worktable and can slide to communicate with the no-go gauge. The drive mechanism simultaneously drives the rotation of the lower mold, the movement of the two sets of blades, and the movement of the go gauge. When the mold opens, the blades cut the guide tube, and the lower mold slides towards the go gauge until the balloon falls into the go gauge. When the mold closes, the go gauge slides away from the no-go gauge and out of the worktable.
[0008] By adopting the above technical solution, and through the cooperation of two sets of blades, go gauges, and no-go gauges, automated material cutting, blanking, and dimensional inspection of balloon production are achieved. In the mold opening stage: the lower mold rotates and slides towards the go gauge, the balloon detaches from the mold and falls into the go gauge, and the blades cut the tubing waste. In the mold closing stage: the lower mold rotates in the opposite direction and resets, the go gauge slides outward from the worktable, and the balloon is moved to the collection position. This integrates production, cutting, and inspection functions, achieving automated operation, improving efficiency and accuracy, and reducing labor costs. It also facilitates the production and inspection of balloons.
[0009] Preferably, the worktable is provided with a guide slide rail and a vibrator. The vibrator abuts against the guide slide rail and the stop gauge. When the mold is opened, one end of the guide slide rail is directly opposite one end of the stop gauge, and the stop gauge abuts against the vibrator.
[0010] By employing the above technical solution, the vibrator causes micro-vibrations in the guide rail and stop gauge, preventing the balloon from getting stuck in the rail due to static electricity or friction, thus ensuring smooth material feeding. During mold opening, the guide rail aligns with the go gauge, and the vibrator continues to operate, assisting the balloon to slide from the mold through the guide rail into the go gauge. Through mechanical vibration and the guiding structure, the reliability of material feeding is improved, production interruptions are avoided, and inspection efficiency is increased.
[0011] Preferably, one end of the guide rail is provided with a guide block, and a guide channel is provided on the guide block. The guide channel is connected to the guide rail, and the guide channel is gradually narrowed from the end near the guide rail to the end away from the guide rail. When the gauge slides to the limit position on the side of the guide channel, the guide channel is connected to the gauge.
[0012] By adopting the above technical solution, the guide channel has a wide inlet and a narrow outlet, expanding the balloon's guide range, reducing the accuracy requirements for the balloon's descent position, and improving the success rate of material dropping. When the balloon enters the tapering channel from the guide rail, the inner wall of the channel guides the balloon to converge towards the center, ultimately sliding precisely into the gauge. This ensures that the gauge and guide channel are perfectly aligned, preventing the balloon from getting stuck at the interface and further improving the stability of material dropping.
[0013] Preferably, each set of blades includes two blades, which are rotatably connected to the lower die and rotate in opposite directions. Each blade is provided with a torsion spring, which always drives the two blades to rotate in opposite directions.
[0014] By adopting the above technical solution, each set of blades consists of two blades rotating in opposite directions and driven by a torsion spring. This structure enables the blades to provide stable and effective shearing force when cutting the conduit. The torsion spring ensures that the blades are always in a working state, which can flexibly adapt to the shearing needs of conduits of different diameters and improve the reliability and adaptability of shearing.
[0015] Preferably, the drive mechanism includes a rotating shaft, a rack, a connecting rod, and a motor. The rotating shaft is rotatably connected to the worktable and has a cam groove. A gear is provided on the lower die. The rack is slidably connected to the worktable, with one end sliding along the cam groove and the other end meshing with the gear. The connecting rod is slidably connected to the worktable, with one end hinged to any blade and the other end always abutting against the rotating shaft. An abutment block is provided on the rotating shaft, and the connecting rod is located on the moving path of the abutment block. A sliding block is slidably connected to the worktable, with a go gauge on the sliding block and a limit block on the sliding block. A limit groove is provided on the rotating shaft, and the limit block slides along the limit groove.
[0016] By adopting the above technical solution, the rotating shaft rotates around its own axis within the worktable. The cam groove, abutment block, and limiting slide groove on the rotating shaft move in a circular motion as the shaft rotates. One end of the rack slides along the cam groove, and driven by the cam groove, the rack reciprocates linearly within the worktable as the rotating shaft rotates; the other end meshes with a gear on the lower die, driving the lower die to rotate. One end of the connecting rod is hinged to the cutting tool, and the other end always abuts against the rotating shaft. As the rotating shaft rotates, the connecting rod reciprocates within the worktable under the action of the abutment block, thereby driving the cutting tool to move. The go gauge is mounted on the sliding block, and the limiting block on the sliding block slides along the limiting slide groove on the rotating shaft, causing the go gauge to reciprocate linearly within the worktable along with the sliding block. Through the cam groove, abutment block, limit slide and other structures on the rotating shaft, together with the rack, connecting rod and other components, the machine can accurately control and coordinate multiple actions such as the rotation of the upper and lower molds, the movement of the blades, and the movement of the go gauge. This allows the various components of the molding machine to work in an orderly manner according to the predetermined production process, ensuring the continuity and stability of the production process.
[0017] Preferably, the cam groove includes a lift section and a fall section. The lift section drives the rack to drive the lower mold to complete the mold closing, and the fall section drives the lower mold to open. A buffer slope is provided at the junction of the lift section and the fall section.
[0018] By adopting the above technical solution, under the action of the cam groove on the rotating shaft, the lower die moves in a circular motion around the rotational connection point with the worktable through the meshing transmission of the rack and pinion gear. The lifting section drives the lower die to rotate in the mold closing phase, and the descending section drives the lower die to rotate in the mold opening phase. The lifting and descending sections of the cam groove drive the mold closing and opening respectively. The buffer slope can reduce the impact and vibration caused by sudden speed changes during the transition between mold closing and opening actions, making the opening and closing actions of the upper and lower dies smoother, reducing the noise during equipment operation, extending the service life of equipment parts, and improving the stability and accuracy of equipment operation.
[0019] Preferably, the workbench is provided with a waste collection trough located below the go gauge, and a balloon collection trough is provided outside the workbench. When the go gauge moves to its limit position outside the workbench, the balloon collection trough is located below the go gauge.
[0020] By adopting the above technical solution, a waste collection trough inside the workbench is used to collect defective balloons, while a balloon collection trough is set outside the workbench. When the gauge moves a qualified balloon to its limit position, the balloon falls into the trough. This achieves automatic collection of finished balloons, facilitating subsequent unified sorting, packaging, and storage of the balloons, and improving the automation level and production efficiency of the production process.
[0021] The main technical effects of this invention are reflected in the following aspects:
[0022] 1. This invention achieves automated material cutting, blanking, and dimensional inspection in balloon production through the cooperation of two sets of blades, a go gauge, and a no-go gauge. During the mold opening stage: the lower mold rotates and slides towards the go gauge, the balloon detaches from the mold and falls into the go gauge, and the blades cut the tubing waste. During the mold closing stage: the lower mold rotates in the opposite direction and resets, the go gauge slides outward from the worktable, and the balloon is moved to the collection position. It integrates production, cutting, and inspection functions, achieving automated operation, improving efficiency and accuracy, and reducing labor costs. It facilitates balloon production and inspection.
[0023] 2. This invention uses a vibrator to generate micro-vibrations in the guide rail and stop gauge, preventing the balloon from getting stuck in the rail due to static electricity or friction, thus ensuring smooth material feeding. During mold opening, the guide rail aligns with the stop gauge, and the vibrator continues to operate, assisting the balloon to slide from the mold through the guide rail into the stop gauge. Through mechanical vibration and the guiding structure, the reliability of material feeding is improved, production interruptions are avoided, and inspection efficiency is increased.
[0024] 3. This invention utilizes a rotating shaft that rotates around its own axis within the worktable. The cam groove, abutment block, and limiting groove on the rotating shaft move in a circular motion as the shaft rotates. One end of the rack slides along the cam groove, and driven by the cam groove, it reciprocates linearly within the worktable as the shaft rotates; the other end meshes with a gear on the lower die, causing the lower die to rotate. One end of the connecting rod is hinged to the blade, while the other end always abuts against the rotating shaft. As the shaft rotates, the connecting rod reciprocates within the worktable under the action of the abutment block, thereby driving the blade. A go gauge is mounted on a sliding block, and a limiting block on the sliding block slides along a limiting groove on the rotating shaft, causing the go gauge to reciprocate linearly within the worktable along with the sliding block. Through the cam groove, abutment block, limit slide and other structures on the rotating shaft, together with the rack, connecting rod and other components, the machine can accurately control and coordinate multiple actions such as the rotation of the upper and lower molds, the movement of the blades, and the movement of the go gauge. This allows the various components of the molding machine to work in an orderly manner according to the predetermined production process, ensuring the continuity and stability of the production process.

Detailed Implementation
[0036] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail to make the technical solution of this application easier to understand and master.
[0037] This application discloses a balloon blow molding machine.
[0038] Reference Figure 1 and Figure 2This embodiment of a balloon blow molding machine includes a worktable 1, a blanking inspection mechanism 3 for inspecting finished products, and a drive mechanism 4. The worktable 1 is provided with an upper mold 5 and a lower mold 6. The upper mold 5 is fixedly connected to the worktable 1, and the lower mold 6 is rotatably connected to the worktable 1. The blanking inspection mechanism 3 includes two sets of blades 7, a go gauge 8, and a no-go gauge 9. The two sets of blades 7 are movably connected to both sides of the lower mold 6 along its length. The no-go gauge 9 is fixedly connected inside the worktable 1. The go gauge 8 is slidably connected to the worktable 1, and the go gauge 8 can slide to communicate with the no-go gauge 9. The drive mechanism 4 is used to drive the rotation of the lower mold 6, the movement of the two sets of blades 7, and the movement of the go gauge 8. When the mold is opened, the blades 7 cut the guide tube, and the lower mold 6 slides toward the go gauge 8 until the balloon falls into the go gauge 8. When the mold is closed, the go gauge 8 slides away from the no-go gauge 9 to the outside of the worktable 1.
[0039] Reference Figure 3 and Figure 4 Through the coordination of two sets of blades 7, go gauge 8, and no-go gauge 9, the system automates the cutting, blanking, and dimensional inspection of balloon production. In the mold opening stage: the lower mold 6 rotates and slides towards the go gauge 8, causing the balloon to detach from the mold and fall into the go gauge 8; the blades 7 cut the tubing waste. In the mold closing stage: the lower mold 6 rotates in the opposite direction and resets; the go gauge 8 slides outward from the worktable 1, transferring the balloon to the collection position. This system integrates production, cutting, and inspection functions, achieving automated operation, improving efficiency and accuracy, and reducing labor costs. It also facilitates the production and inspection of balloons.
[0040] Reference Figure 5 and Figure 6 A guide rail 10 and a vibrator 11 are fixedly connected to the worktable 1. The vibrator 11 abuts against the guide rail 10 and the stop gauge 9. When the mold opens, one end of the guide rail 10 is aligned with one end of the go gauge 8, and the go gauge 8 abuts against the vibrator 11. The vibrator 11 causes the guide rail 10 and the stop gauge 9 to vibrate slightly, preventing the balloon from getting stuck in the rail due to static electricity or friction, ensuring smooth material feeding. When the mold opens, the guide rail 10 aligns with the go gauge 8, and the vibrator 11 continues to work, assisting the balloon to slide from the mold through the guide rail 10 into the go gauge 8. Through mechanical vibration and the guiding structure, the reliability of material feeding is improved, production interruptions are avoided, and inspection efficiency is increased.
[0041] Reference Figure 5 and Figure 8A guide block 12 is fixedly connected to the end of the guide rail 10 away from the lower mold 6. A guide channel 13 is provided on the guide block 12, which connects to the guide rail 10. The guide channel 13 tapers from the end closest to the guide rail 10 to the end furthest from the guide rail 10. When the go gauge 8 slides to its limit position towards the guide channel 13, the guide channel 13 connects with the go gauge 8. The guide channel 13 has a wide inlet and a narrow outlet, expanding the balloon's guide range, reducing the accuracy requirements for the balloon's falling position, and improving the success rate of balloon insertion. When the balloon enters the tapering channel from the guide rail 10, the inner wall of the channel guides the balloon towards the center, ultimately sliding precisely into the go gauge 8. This ensures that the go gauge 8 and the guide channel 13 are completely aligned, preventing the balloon from getting stuck at the interface and further improving insertion stability.
[0042] Reference Figure 4 and Figure 5 Each set of blades 7 comprises two blades 7, which are rotatably connected to the lower die 6, and the two blades 7 rotate in opposite directions. Torsion springs are fixedly connected to both blades 7, and the torsion springs always drive the two blades 7 to rotate in opposite directions. Each set of blades 7 consists of two counter-rotating blades 7 driven by torsion springs. This structure allows the blades 7 to provide stable and effective shearing force when cutting conduits. The torsion springs ensure that the blades 7 are always in a working state, flexibly adapting to the shearing needs of conduits of different diameters, improving the reliability and adaptability of the shearing process.
[0043] Reference Figure 6 , Figure 7 and Figure 8 The drive mechanism 4 includes a rotating shaft 15, a rack 16, two connecting rods 17, and a motor 18. The rotating shaft 15 is rotatably connected to the worktable 1, and a cam groove 19 is provided on the rotating shaft 15. A gear 20 is fixedly connected to the lower mold 6. The rack 16 is slidably connected to the worktable 1 in the vertical direction. One end of the rack 16 is slidably connected to the cam groove 19 along the bottom wall of the cam groove 19, and the other end of the rack 16 is meshed with the gear 20. The connecting rods 17 are slidably connected to the worktable 1 in the vertical direction, and one end of the two connecting rods 17 is connected to the gear 20. The two connecting rods 17 are respectively hinged and slidably connected to any one of the blades 7 on both sides of the lower mold 6. The other ends of the two connecting rods 17 are simultaneously fixedly connected to the connecting plate 30. The connecting plate 30 always abuts against the rotating shaft 15. The rotating shaft 15 is provided with an abutment block 24. The connecting plate 30 is located on the moving path of the abutment block 24. A sliding block 21 is slidably connected inside the worktable 1. A go gauge 8 is provided on the sliding block 21. A limit block 22 is provided on the sliding block 21. A limit groove 23 is provided on the rotating shaft 15. The limit block 22 slides along the limit groove 23.
[0044] Reference Figure 7 and Figure 8The rotating shaft 15 rotates around its own axis within the worktable 1. The cam groove 19, abutment block 24, and limiting slide groove 23 on the rotating shaft 15 rotate in a circular motion. One end of the rack 16 slides along the cam groove 19. Driven by the cam groove 19, the rack 16 reciprocates linearly within the worktable 1 as the rotating shaft 15 rotates; the other end meshes with the gear 20 on the lower die 6, causing the lower die 6 to rotate. One end of the connecting rod 17 is hinged to the blade 7, and the other end always abuts against the rotating shaft 15. As the rotating shaft 15 rotates, the connecting rod 17 reciprocates within the worktable 1 under the action of the abutment block 24, thereby driving the blade 7 to move. The go gauge 8 is mounted on the sliding block 21. The limiting block 22 on the sliding block 21 slides along the limiting slide groove 23 on the rotating shaft 15, causing the go gauge 8 to reciprocate linearly within the worktable 1 along with the sliding block 21. Through the cam groove 19, abutment block 24, limit slide 23 and other structures on the rotating shaft 15, and in conjunction with the rack 16, connecting rod 17 and other components, the machine achieves precise control and coordinated operation of multiple actions such as the rotation of the upper mold 5 and lower mold 6, the movement of the blade 7, and the movement of the go gauge 8. This enables the various components of the molding machine to work in an orderly manner according to the predetermined production process, ensuring the continuity and stability of the production process.
[0045] Reference Figure 9 The cam groove 19 includes a lift section 25 and a fall section. The lift section 25 drives the rack 16 to drive the lower die 6 to close the mold, and the fall section drives the lower die 6 to open the mold. A buffer slope 27 is provided at the connection between the lift section 25 and the fall section. Under the action of the cam groove 19 on the rotating shaft 15, the lower die 6 moves in a circular motion around the rotation connection point with the worktable 1 through the meshing transmission between the rack 16 and the gear 20 of the lower die 6. The lift section 25 drives the lower die 6 to rotate to close the mold, and the fall section drives the lower die 6 to rotate to open the mold. The lift section 25 and the fall section of the cam groove 19 drive the mold closing and opening respectively. The buffer slope 27 can reduce the impact and vibration caused by sudden speed changes when the mold closing and opening actions are switched, making the opening and closing actions of the upper and lower dies 6 smoother, reducing the noise during equipment operation, extending the service life of equipment parts, and improving the stability and accuracy of equipment operation.
[0046] Reference Figure 1 and Figure 2 The workbench 1 is equipped with a waste collection trough 29 located below the go-no-go gauge 9. A balloon collection trough 28 is installed outside the workbench 1. When the go-no-go gauge 8 moves to its limit position outside the workbench 1, the balloon collection trough 28 is located below the go-no-go gauge 8. The waste collection trough 29 inside the workbench 1 is used to collect defective balloons. The balloon collection trough 28 outside the workbench 1 is used when the go-no-go gauge 8 moves a qualified balloon to its limit position, causing the balloon to fall into it. This achieves automatic collection of finished balloons, facilitating subsequent unified sorting, packaging, and storage of the balloons, and improving the automation level and production efficiency of the production process.
[0047] Reference Figure 7 and Figure 8 The drive mechanism 4 is activated: the motor 18 drives the rotating shaft 15 to rotate. The rotating shaft 15 has a cam groove 19, whose lifting section 25 and falling section control the mold closing and opening actions of the lower mold 6, respectively. The lifting section 25 contacts one end of the rack 16, driving the rack 16 to move linearly within the worktable 1. The other end of the rack 16 meshes with the gear 20 on the lower mold 6, driving the lower mold 6 to rotate and achieve mold closing. The falling section causes the lower mold 6 to rotate in the opposite direction to open. At the same time, the rotating shaft 15 is provided with an abutment block 24. One end of the connecting rod 17 is hinged to the blade 7, and the other end abuts against the rotating shaft 15. When the rotating shaft 15 rotates, the abutment block 24 acts on the connecting rod 17, causing it to swing and drive the blade 7 to rotate, thus achieving the opening and closing action of the blade 7. The limiting groove 23 on the rotating shaft 15 cooperates with the limiting block 22 on the sliding block 21 to control the movement of the go gauge 8. When the mold is closed, the go gauge 8 moves outward from the worktable 1, and when the mold is opened, it moves in the direction of the mold.
[0048] Reference Figure 4 and Figure 8 Mold closing process: The upper mold 5 and lower mold 6 rotate towards each other under the action of the drive mechanism 4, gradually approaching each other until they close, completing the mold closing action. During this process, the go gauge 8 moves to its limit position outside the worktable 1 under the drive mechanism 4.
[0049] Reference Figure 4 and Figure 8 Blow molding process: After the mold is closed, the relevant operations are performed inside the mold by the clamping inflation mechanism to complete the blow molding of the balloon.
[0050] Reference Figure 3 and Figure 7 The mold opening and cutting process: The mold opens, and the upper mold 5 and lower mold 6 rotate in opposite directions to separate. At this time, under the action of the drive mechanism 4, the blade 7 rotates and cuts the catheter connecting the balloon.
[0051] Reference Figure 10 The balloon delivery and inspection process: The lower mold 6 slides towards the go gauge 8, and the balloon detaches from the mold and falls into the go gauge 8. Under the action of the vibrator 11, the balloon moves within the go gauge 8. The guide rail 10 and guide block 12 play a guiding role, ensuring that the balloon accurately enters the go gauge 8 and moves smoothly. During this process, the balloon dimensions are inspected by the go gauge 8 and the no-go gauge 9.
[0052] Reference Figure 1 and Figure 5 Waste and finished product collection process: During production, defective balloons fall into the waste collection trough 29 located below the no-go gauge 9. Balloons that pass inspection fall into the balloon collection trough 28 when the go gauge 8 moves to the outer limit position of the worktable 1, completing the finished product collection.
[0053] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
