Description

Technical Field

[0001] The present invention relates to the technical field of balloon molding, in particular to a balloon blow molding machine. Background Art

[0002] Balloon blow molding machine is a special equipment used to produce balloon products such as medical balloons. Its core principle is to use the blow molding process to make plastic particles or sheet materials into hollow balloons with specific shapes and functions.

[0003] The invention with announcement number CN222061182U relates to a balloon forming machine, in which one side of the catheter is clamped by a clamping cylinder, while the other side of the catheter passes through the mold cavity and is clamped by an air clamp. After the two ends of the catheter are clamped stably, the catheter is regionally heated by a heating block. After the catheter is regionally heated, the first guide rail drives the first movable platform together with the air clamp and the second guide rail drives the fourth movable platform together with the clamping cylinder to move in opposite directions at the same time. When moving to a certain distance in the opposite direction, the heated part of the catheter will be stretched to the required thickness. While moving in the opposite direction, the clamping cylinder transports inert gas into the catheter through the air outlet, so that the inert gas expands the inner wall of the catheter that has been regionally heated, thereby making the outer wall of the catheter close to the inner wall of the mold cavity, and finally forming a balloon.

[0004] However, the above-mentioned balloon blow molding machine does not have the function of detecting the diameter of the balloon. During use, the balloon formed on the catheter needs to be manually cut off and tested one by one through a go / no-go gauge. Each molded balloon needs to be inspected manually and the catheter needs to be clamped, which causes inconvenience to the production and inspection of the balloon, resulting in low production efficiency of the balloon. Summary of the Invention

[0005] In order to facilitate the production and inspection of balloons, the present application provides a balloon blow molding machine.

[0006] The present application provides a balloon blow molding machine that adopts the following technical solutions: A balloon blow molding machine includes a workbench and a blanking inspection mechanism and a driving mechanism for inspecting finished products. The workbench is provided with an upper mold and a lower mold, and the lower mold is rotatably connected to the workbench. The blanking inspection mechanism includes two groups of blades, a go gauge and a stop gauge. The two groups of blades are movably connected to both sides of the lower mold, and the stop gauge is fixedly connected to the workbench. The go gauge is slidably connected to the workbench and can be slid to be connected to the stop gauge. The driving mechanism is simultaneously used to drive the rotation of the lower mold, the movement of the two groups of blades and the movement of the go gauge. When the mold is opened, the blade cuts the catheter, and the lower mold slides toward the side of the go gauge until the balloon falls into the go gauge. When the mold is closed, the go gauge slides to the outside of the workbench toward the side away from the stop gauge.

[0007] By employing this technical solution, two sets of blades, a go gauge, and a stop gauge are combined to achieve automated cutting, blanking, and dimensional inspection for balloon production. During the mold opening phase, the lower mold rotates and slides toward the go gauge, releasing the balloon from the mold and dropping it into the go gauge, where the blades shear the catheter waste. During the mold closing phase, the lower mold rotates in the opposite direction and resets, while the go gauge slides away from the workbench, moving the balloon to a collection location. This integrated production, cutting, and inspection functions enable automated operations, improving efficiency and precision while reducing labor costs. This facilitates balloon production and inspection.

[0008] Preferably, the workbench is provided with a guide rail and a vibrator, the vibrator abuts against the guide rail and the stop gauge, and when the mold is opened, one end of the guide rail faces one end of the go gauge, and the go gauge abuts against the vibrator.

[0009] By employing this technical solution, the vibrator micro-vibrates the guide rail and the stop gauge, preventing the balloon from becoming stuck in the rail due to static electricity or friction, ensuring smooth blanking. During mold opening, the guide rail mates with the go gauge, and the vibrator continuously operates, assisting the balloon in sliding from the mold, through the guide rail, and into the go gauge. This mechanical vibration and guiding structure improve blanking reliability, avoid production interruptions, and enhance inspection efficiency.

[0010] Preferably, a guide block is provided at one end of the guide slide rail, and a guide channel is opened on the guide block. The guide channel is docked with the guide slide rail, and the guide channel is gradually tapered from one end close to the guide slide rail to the end away from the guide slide rail. When the through gauge slides toward one side of the guide channel to the extreme position, the guide channel is docked with the through gauge.

[0011] By adopting this technical solution, the guide channel has a wide entrance and a narrow exit, expanding the range for the balloon to enter, reducing the requirements for the precise placement of the balloon, and improving the success rate of blanking. As the balloon enters the tapered channel from the guide rail, the inner wall of the channel guides the balloon toward the center, ultimately allowing it to slide 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 blanking stability.

[0012] Preferably, each group of blades includes two blades, which are rotatably connected to the lower mold and rotate in opposite directions. A torsion spring is provided on the two blades, which always drives the two blades to rotate in opposite directions.

[0013] By adopting the above technical solution, each set of blades consists of two blades rotating in opposite directions and driven by torsion springs. This structure enables the blades to provide stable and effective shearing force when cutting the catheter. The action of the torsion spring ensures that the blades are always in a working state, which can flexibly adapt to the cutting requirements of catheters of different diameters and improve the reliability and adaptability of cutting.

[0014] Preferably, the driving mechanism includes a rotating shaft, a rack, a connecting rod and a motor, the rotating shaft is rotatably connected to the workbench, a cam groove is provided on the rotating shaft, the lower mold is provided with a gear, the rack is slidably connected to the workbench, one end of the rack slides along the cam groove, and the other end of the rack is meshed with the gear, the connecting rod is slidably connected to the workbench, one end of the connecting rod is hingedly connected to any blade, and the other end of the connecting rod always abuts against the rotating shaft, the rotating shaft is provided with an abutment block, the connecting rod is located in the moving path of the abutment block, a sliding block is slidably connected to the workbench, the through gauge is provided on the sliding block, a limit block is provided on the sliding block, a limit slide groove is provided on the rotating shaft, and the limit block slides along the limit slide groove.

[0015] By adopting the above technical solution, the rotating shaft rotates around its own axis in the workbench, and the cam groove, abutment block, limit slide groove and other structures on the rotating shaft perform circular motion as the rotating shaft rotates. One end of the rack slides along the cam groove, and as the rotating shaft rotates, driven by the cam groove, the rack performs linear reciprocating motion in the workbench; the other end engages with the gear on the lower mold, driving the lower mold to rotate. One end of the connecting rod is hinged to the blade, and the other end is always abutted against the rotating shaft. As the rotating shaft rotates, under the action of the abutment block, the connecting rod performs reciprocating motion in the workbench, thereby driving the blade to move. The through gauge is set on the sliding block, and the limit block on the sliding block slides along the limit slide groove on the rotating shaft, so that the through gauge performs linear reciprocating motion in the workbench along with the sliding block. Through the cam groove, abutment block, limit slide and other structures on the rotating shaft, in conjunction with components such as the rack and connecting rod, precise control and coordination of multiple actions such as the rotation of the upper and lower molds, the movement of the blades, and the movement of the gauge are achieved, so that the various components of the molding machine can work in an orderly manner according to the predetermined production process, ensuring the continuity and stability of the production process.

[0016] Preferably, the cam groove includes a lifting section and a descending section, the lifting section drives the rack to drive the lower mold to complete mold closing, and the descending section drives the lower mold to open the mold, and a buffer slope is provided at the connection between the lifting section and the descending section.

[0017] By adopting this technical solution, the lower die performs circular motion around its pivot point with the worktable, driven by the cam groove on the rotating shaft and driven by the meshing transmission of the rack and lower die gear. The lifting section drives the lower die for closing rotation, while the lowering section drives the lower die for opening rotation. The lifting and lowering sections of the cam groove respectively drive the closing and opening of the mold. The provision of a buffer slope reduces the impact and vibration caused by sudden speed changes during the transition between closing and opening, making the opening and closing of the upper and lower dies smoother, reducing equipment operating noise, extending the service life of equipment components, and improving the smoothness and precision of equipment operation.

[0018] Preferably, a waste collection trough is provided inside the workbench, and the waste collection trough is located below the stop gauge. A balloon collection trough is provided outside the workbench, and when the through gauge moves to the extreme position outside the workbench, the balloon collection trough is located below the through gauge.

[0019] By adopting this technical solution, a waste collection trough inside the workbench is used to collect unqualified balloons, and a balloon collection trough is set up outside the workbench, into which qualified balloons fall when the gauge moves them to the limit. This achieves automatic collection of finished balloons, facilitating subsequent unified sorting, packaging, and storage of the balloons, improving the degree of automation and production efficiency.

[0020] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention realizes the automated shearing, blanking and size inspection of balloon production through the cooperation of two sets of blades, a go gauge and a stop gauge. Mold opening stage: the lower mold rotates and slides in the direction of the go gauge, the balloon falls out of the mold and into the go gauge, and the blades shear the catheter waste. Mold closing stage: the lower mold rotates in the opposite direction and resets, the go gauge slides outward from the workbench, and the balloon is moved to the collection position. The integrated production, shearing and inspection functions realize automated operations, improve efficiency and accuracy, and reduce labor costs. It is convenient for the production and inspection of balloons; 2. The present invention uses a vibrator to generate micro-vibrations in the guide rail and the stop gauge, preventing the balloon from getting stuck in the rail due to static electricity or friction, ensuring smooth blanking. When the mold is opened, the guide rail and the stop gauge are docked, and the vibrator continues to work, assisting the balloon in sliding from the mold through the guide rail and into the stop gauge. Through mechanical vibration and the guide structure, blanking reliability is improved, production interruptions are avoided, and inspection efficiency is increased. 3. The present invention rotates the rotating shaft around its own axis in the workbench, and the cam groove, abutment block, limit slide groove and other structures on the rotating shaft make circular motion as the rotating shaft rotates. One end of the rack slides along the cam groove, and as the rotating shaft rotates, the rack makes linear reciprocating motion in the workbench under the drive of the cam groove; the other end engages with the gear on the lower mold, driving the lower mold to rotate. One end of the connecting rod is hinged to the blade, and the other end is always abutted on the rotating shaft. As the rotating shaft rotates, under the action of the abutment block, the connecting rod makes reciprocating motion in the workbench, thereby driving the blade to move. The through gauge is set on the sliding block, and the limit block on the sliding block slides along the limit slide groove on the rotating shaft, so that the through gauge makes linear reciprocating motion in the workbench along with the sliding block. Through the cam groove, abutment block, limit slide and other structures on the rotating shaft, in conjunction with components such as the rack and connecting rod, precise control and coordination of multiple actions such as the rotation of the upper and lower molds, the movement of the blades, and the movement of the gauge are achieved, so that the various components of the molding machine can work in an orderly manner according to the predetermined production process, ensuring the continuity and stability of the production process.

[0032] The following is combined with Figure 1-10 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0033] The embodiment of the present application discloses a balloon blow molding machine.

[0034] Reference Figure 1 and Figure 2, a balloon blow molding machine of this embodiment includes a workbench 1, and also includes a blanking inspection mechanism 3 and a driving mechanism 4 for inspecting the finished product. An upper mold 5 and a lower mold 6 are provided on the workbench 1. The upper mold 5 is fixedly connected to the workbench 1, and the lower mold 6 is rotatably connected to the workbench 1. The blanking inspection mechanism 3 includes two sets of blades 7, a through gauge 8 and a stop gauge 9. The two sets of blades 7 are movably connected to both sides of the length direction of the lower mold 6 respectively, and the stop gauge 9 is fixedly connected to the workbench 1. The through gauge 8 is slidably connected to the workbench 1, and the through gauge 8 can be slid to be connected with the stop gauge 9. The driving mechanism 4 is simultaneously used to drive the rotation of the lower mold 6, the activity of the two sets of blades 7 and the movement of the through gauge 8. When the mold is opened, the blade 7 cuts the catheter, and the lower mold 6 slides toward the side of the through gauge 8 until the balloon falls into the through gauge 8. When the mold is closed, the through gauge 8 slides to the outside of the workbench 1 toward the side away from the stop gauge 9.

[0035] Reference Figure 3 and Figure 4 The two sets of blades 7, go gauge 8, and stop gauge 9 collaborate to achieve automated shearing, blanking, and dimensional inspection for balloon production. During the mold opening phase, the lower mold 6 rotates and slides toward the go gauge 8. The balloon escapes from the mold and falls into the go gauge 8, where the blade 7 shears the catheter waste. During the mold closing phase, the lower mold 6 rotates in the opposite direction and resets. The go gauge 8 slides outward from the workbench 1, moving the balloon to a collection location. This integrated production, shearing, and inspection functions enable automated operations, improve efficiency and precision, and reduce labor costs, facilitating balloon production and inspection.

[0036] Reference Figure 5 and Figure 6 A guide rail 10 and a vibrator 11 are fixedly connected to the workbench 1. The vibrator 11 abuts against the guide rail 10 and the go gauge 9. When the mold is opened, one end of the guide rail 10 is opposite to 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 go gauge 9 to generate micro-vibrations to prevent the balloon from getting stuck in the track due to static electricity or friction, ensuring smooth blanking. When the mold is opened, the guide rail 10 docks with the go gauge 8, and the vibrator 11 works continuously to assist the balloon in sliding from the mold through the guide rail 10 into the go gauge 8. Through mechanical vibration and guiding structure, the reliability of blanking is improved, production interruptions are avoided, and detection efficiency is improved.

[0037] Reference Figure 5 and Figure 8, the end of the guide rail 10 away from the lower mold 6 is fixedly connected to a guide block 12, and a guide channel 13 is provided on the guide block 12. The guide channel 13 is docked with the guide rail 10, and the guide channel 13 is tapered from the end close to the guide rail 10 to the end away from the guide rail 10. When the through gauge 8 slides to the extreme position toward the side of the guide channel 13, the guide channel 13 docks with the through gauge 8. The entrance of the guide channel 13 is wide and the exit is narrow, which expands the range of balloon introduction, reduces the requirements for the accuracy of the balloon falling position, and improves the success rate of blanking. When the balloon enters the tapered channel from the guide rail 10, the inner wall of the channel guides the balloon to gather towards the center, and finally slides accurately into the through gauge 8. Ensure that the through gauge 8 is completely aligned with the guide channel 13 to avoid the balloon being stuck at the interface, further improving the stability of blanking.

[0038] Reference Figure 4 and Figure 5 Each set of blades 7 includes two blades 7 , each rotatably connected to the lower die 6 . The two blades 7 rotate in opposite directions, and a torsion spring is fixedly connected to each blade 7 , which always drives the two blades 7 to rotate in opposite directions. Each set of blades 7 consists of two blades 7 that rotate in opposite directions and are driven by torsion springs. This structure enables the blades 7 to provide stable and effective shearing force when cutting catheters. The torsion spring ensures that the blades 7 are always in an operational state, allowing for flexible adaptation to the cutting requirements of catheters of different diameters, improving the reliability and adaptability of the cutting process.

[0039] Reference Figure 6 、 Figure 7 and Figure 8 The driving 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 workbench 1. 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 workbench 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. The other end of the rack 16 is meshed with the gear 20. The connecting rod 17 is slidably connected to the workbench 1 in the vertical direction. One end of the two connecting rods 17 They are respectively hingedly connected and slidably connected to any blade 7 on both sides of the lower mold 6. The other ends of the two connecting rods 17 are fixedly connected to the connecting plate 30 at the same time. The connecting plate 30 is always in contact with 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 in the workbench 1. The through gauge 8 is provided on the sliding block 21. A limit block 22 is provided on the sliding block 21. A limit slide 23 is provided on the rotating shaft 15. The limit block 22 slides along the limit slide 23.

[0040] Reference Figure 7 and Figure 8The rotating shaft 15 rotates about its own axis within the workbench 1. The cam groove 19, abutment block 24, and limiting slide 23 on the rotating shaft 15 also 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 performs linear reciprocating motion within the workbench 1 as the rotating shaft 15 rotates. The other end engages with the gear 20 on the lower die 6, driving the lower die 6 to rotate. One end of the connecting rod 17 is hinged to the blade 7, while the other end always abuts the rotating shaft 15. As the rotating shaft 15 rotates, the abutment block 24 causes the connecting rod 17 to reciprocate within the workbench 1, thereby driving the blade 7. The gauge 8 is mounted on the sliding block 21. The limiting block 22 on the sliding block 21 slides along the limiting slide 23 on the rotating shaft 15, causing the gauge 8 to perform linear reciprocating motion within the workbench 1 along with the sliding block 21. By means of the cam groove 19, the abutment block 24, the limiting slide groove 23 and other structures on the rotating shaft 15, in cooperation with the rack 16, the connecting rod 17 and other components, precise control and coordination of multiple actions such as the rotation of the upper mold 5 and the lower mold 6, the movement of the blade 7, and the movement of the pass gauge 8 are achieved, so that the various components of the molding machine can work in an orderly manner according to the predetermined production process, ensuring the continuity and stability of the production process.

[0041] Reference Figure 9 The cam groove 19 includes a lifting section 25 and a lowering section. The lifting section 25 drives the rack 16 to drive the lower mold 6 to complete mold closing, and the lowering section drives the lower mold 6 to open the mold. A buffer slope 27 is provided at the junction of the lifting section 25 and the lowering section. Under the action of the cam groove 19 on the rotating shaft 15, through the meshing transmission of the rack 16 and the gear 20 of the lower mold 6, the lower mold 6 performs circular motion around the rotating connection point with the workbench 1. The lifting section 25 drives the lower mold 6 to rotate to close the mold, and the lowering section drives the lower mold 6 to rotate to open the mold. The lifting section 25 and the lowering section of the cam groove 19 drive the mold closing and mold opening respectively. The setting of the buffer slope 27 can reduce the impact and vibration caused by the sudden change in speed when the mold closing and mold opening actions are switched, making the opening and closing actions of the upper and lower molds 6 smoother, reducing the noise during equipment operation, extending the service life of equipment components, and improving the stability and precision of equipment operation.

[0042] Reference Figure 1 and Figure 2 The workbench 1 is equipped with a waste collection trough 29 located below the stop gauge 9. A balloon collection trough 28 is installed outside the workbench 1. When the go gauge 8 moves to its limit position outside the workbench 1, the balloon collection trough 28 is located below the go gauge 8. The waste collection trough 29 inside the workbench 1 is used to collect unqualified balloons. The balloon collection trough 28 outside the workbench 1 is used to collect qualified balloons when the go gauge 8 moves to its limit position. This achieves automatic collection of finished balloons, facilitates subsequent unified organization, packaging, and storage of the balloons, and improves the degree of automation and production efficiency.

[0043] Reference Figure 7 and Figure 8 , the drive mechanism 4 is started: the motor 18 drives the rotating shaft 15 to rotate, and the rotating shaft 15 is provided with a cam groove 19. Its lifting section 25 and lowering section respectively control the closing and opening of the lower mold 6. The lifting section 25 contacts one end of the rack 16, driving the rack 16 to make linear motion within the workbench 1. The other end of the rack 16 engages with the gear 20 on the lower mold 6, driving the lower mold 6 to rotate and achieve the closing of the mold; the lowering section causes the lower mold 6 to rotate in the opposite direction to open the mold. At the same time, an abutment block 24 is provided on the rotating shaft 15. One end of the connecting rod 17 is hinged to the blade 7, and the other end abuts the rotating shaft 15. When the rotating shaft 15 rotates, the abutment block 24 acts on the connecting rod 17, causing it to swing, driving the blade 7 to rotate, and realizing the opening and closing 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. The go gauge 8 moves outward from the workbench 1 when the mold is closed, and moves toward the mold when the mold is opened.

[0044] Reference Figure 4 and Figure 8 , Mold closing process: The upper mold 5 and the lower mold 6 rotate toward each other under the action of the driving mechanism 4, gradually approaching until they are closed, completing the mold closing action. During this process, the go gauge 8 is driven by the driving mechanism 4 to move outward from the workbench 1 to the extreme position.

[0045] Reference Figure 4 and Figure 8 , Blow molding process: After the mold is closed, the relevant operations are performed inside the mold by clamping the inflation mechanism to complete the blow molding of the balloon.

[0046] Reference Figure 3 and Figure 7 , Mold opening and shearing process: the mold is opened, and the upper mold 5 and the lower mold 6 rotate in opposite directions to separate. At this time, under the action of the driving mechanism 4, the blade 7 rotates to shear the catheter connected to the balloon.

[0047] Reference Figure 10 Balloon conveying and inspection process: The lower mold 6 slides toward the side of the go gauge 8, and the balloon is released from the mold and falls into the go gauge 8. Under the action of the vibrator 11, the go gauge 8 moves the balloon inside 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 size is inspected by the go gauge 8 and the stop gauge 9.

[0048] Reference Figure 1 and Figure 5 , Waste and finished product collection process: The unqualified balloons in the production process fall into the waste collection tank 29 located below the stop gauge 9. The qualified balloons, as the go gauge 8 moves to the outer limit position of the workbench 1, fall into the balloon collection tank 28 to complete the collection of finished products.

[0049] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
