Description

Technical Field

[0001] This application relates to the technical field of medical device manufacturing, and in particular to a balloon molding machine. Background Technology

[0002] Currently, balloons are widely used in minimally invasive interventional treatments in many fields such as cardiovascular, digestive, urological, and obstetrics and gynecology. They are especially used in clinical scenarios such as coronary artery stenosis dilation, drug-coated balloon intervention for vascular lesions, cervical ripening and delivery promotion and postpartum hemostasis, and dilation of gastrointestinal and urinary tract stenosis, becoming a core consumable for achieving precise, minimally invasive, and efficient treatment.

[0003] In the prior art, a balloon forming machine includes a machine body with a base. The base is separately equipped with a heating device for thermoplastic forming of a balloon tube blank and a cooling device for cooling and shaping the formed portion. A stretching device for stretching the balloon tube blank is slidably connected to one side of the heating device. During balloon processing, a balloon tube blank of suitable length is first cut according to the finished product specifications. A person manually holds one end of the balloon tube blank with one hand, clamps and fixes the other end of the balloon tube blank to the stretching device, and then pushes the tube blank into the heating device for forming. After the center of the balloon is thermoplastic formed, the person manually removes the tube blank from the heating device and quickly moves it into the cooling device to cool and shape the formed portion of the balloon.

[0004] Regarding the aforementioned patents, because the heating and cooling devices are arranged separately, manual intervention is required throughout the balloon processing. This not only significantly increases labor costs, but also makes the balloon blank susceptible to slight deformation in the forming part due to external environmental influences or improper manual operation during the process of removing it from the heating device and transferring it to the cooling device. This affects the forming accuracy of the balloon and urgently needs improvement. Summary of the Invention

[0005] To reduce the decrease in balloon forming accuracy caused by improper manual operation or external environmental interference during the balloon transfer from the heating device to the cooling device in the balloon blank production process, this application provides a balloon forming machine.

[0006] This application provides a balloon molding machine with the following technical solution: It includes a base, on which a sliding cavity is formed. An air inlet seat and a clamping seat are slidably connected to both sides of the sliding cavity. A temperature control seat is slidably connected between the air inlet seat and the clamping seat. A first cylinder for driving the temperature control seat to slide back and forth is installed in the sliding cavity. The first cylinder is located on both sides of the air inlet seat and is symmetrically arranged. A mold cavity for fixing the balloon mold is formed on the temperature control seat. A heat exchange cavity is also formed on the temperature control seat. Two temperature control tubes are inserted into the heat exchange cavity. The ends of the two temperature control tubes away from the heat exchange cavity are connected to a water supply assembly. The two temperature control tubes are used to realize the circulation of hot and cold media in and out of the heat exchange cavity. A plug fixing block for placing the balloon mold plug is slidably connected to the end of the temperature control seat away from the air inlet seat. A second cylinder for driving the plug fixing block is installed in the sliding cavity. The second cylinder is located on both sides of the clamping seat and is symmetrically arranged.

[0007] By adopting the above technical solution, during balloon processing, the balloon mold is first placed in the temperature control seat, and then the balloon mold plug is clamped onto the plug fixing block for positioning. Subsequently, the first and second cylinders are activated to drive the temperature control seat and the plug fixing block to move towards each other. After the temperature control seat and the plug fixing block are aligned, the balloon blank to be processed is clamped, and a sealing ring is installed on the sealing block of the air inlet seat to ensure sealing performance during balloon processing. After the above setup and adjustment are completed, the entire balloon forming machine program is started, and the equipment enters the processing stage. High-temperature liquid, via the temperature control tube, provides the heat required for balloon forming during the balloon production process. After the balloon is formed, the equipment switches to the water cooling stage, where low-temperature liquid, via the temperature control tube, achieves rapid cooling of the processed balloon.

[0008] Preferably, the water supply assembly includes a high-temperature liquid tank and a low-temperature liquid tank fixed on a base. A temperature control valve is mounted on the temperature control pipe. A switch valve block is slidably connected inside the temperature control valve. The temperature control valve is provided with a first driving component for driving the switch valve block to retract or extend. The switch valve block has a first high-temperature liquid passage and a second high-temperature liquid passage. A first temperature control valve chamber and a second temperature control valve chamber are opened on one side of the temperature control valve and communicate with the high-temperature liquid tank. A third temperature control valve chamber and a fourth temperature control valve chamber are opened on the other side of the temperature control valve and communicate with the temperature control base. When the switch valve block retracts, the two ends of the first high-temperature liquid passage are connected to the first temperature control valve chamber and the third temperature control valve chamber, respectively. The second high-temperature liquid passage is connected to the second temperature control valve chamber and the fourth temperature control valve chamber, respectively. A first low-temperature liquid chamber and a second low-temperature liquid chamber are opened inside the switch valve block and communicate with the low-temperature liquid tank. When the switch valve extends, the first low-temperature liquid chamber is connected to the fourth temperature control valve chamber; the second low-temperature liquid chamber is connected to the third temperature control valve chamber.

[0009] By adopting the above technical solution, during the balloon processing heating stage, the switch valve block inside the temperature control valve is pushed, so that the first and second high-temperature liquid passage holes on the switch valve block are connected to each temperature control valve cavity. The high-temperature liquid is transported to the temperature control seat through the temperature control pipe, providing the required heating temperature for balloon forming. After the balloon processing is completed, it enters the water cooling stage. The switch valve block is pulled to make the two high-temperature liquid passage holes staggered from each temperature control valve cavity. The switch valve block closes the first and second temperature control valve cavities, achieving isolation and blocking from the high-temperature liquid. The low-temperature liquid enters the first low-temperature liquid tank and is transported to the temperature control seat through the fourth temperature control cavity. The cooling water after heat exchange flows into the low-temperature circulation pipe through the drain hole, thereby achieving rapid cooling of the processed balloon.

[0010] Preferably, both the air intake seat and the clamping seat have a fixed idler seat at their bottoms. The idler seat has a sliding groove and an idler cavity inside. A screw for idler rotation is rotatably connected inside the idler cavity. Screw sleeves are threaded onto two screws, and the two screw sleeves are fixed to the bottoms of the air intake seat and the clamping seat, respectively. Through the threaded transmission between the screws and screw sleeves, the air intake seat and the clamping seat are driven to perform horizontal reciprocating motion in the sliding groove. A third driving component and a second driving component for driving the two screws to idler are also connected to one end of each screw.

[0011] By adopting the above technical solution, during the processing of the balloon, the second and third driving components drive the corresponding screw transmission to achieve precise displacement adjustment of the air intake seat and clamping seat. The transmission is stable and reliable, with high positioning accuracy. It can adapt to the clamping and forming position adjustment requirements of different specifications of tube blanks in balloon processing, effectively improving the forming accuracy of the balloon and the stability of equipment operation.

[0012] Preferably, the air inlet seat has an air inlet hole for injecting nitrogen into the balloon tube blank that passes through the air inlet seat, and a sealing block is installed on the air inlet seat, with an annular sealing groove on the surface of the sealing block.

[0013] By adopting the above technical solution, a sealing ring is installed on the sealing groove of the air inlet seat during the balloon molding process to ensure airtightness during balloon processing, thereby improving the precision of balloon molding and the quality of the finished product. When the temperature inside the temperature control seat reaches the set value of the balloon molding process, nitrogen gas required for balloon molding is introduced into the temperature control seat through the air inlet seat, causing the center of the balloon blank to expand and bulge, forming the balloon molding outline.

[0014] Preferably, the water supply assembly includes a control valve block, a hot liquid tank, and a cold liquid tank. The control valve block has a control valve chamber connected to two temperature control pipes. The side walls of the two control valve chambers have injection holes connected to the hot liquid tank and the cold liquid tank, respectively. The heat exchange chamber is spirally arranged, and a circulating slider is slidably connected within the heat exchange chamber. The circulating slider slides within the temperature control pipes and the control valve chamber. The side wall of the control valve chamber has a telescopic groove, and the bottom of the telescopic groove has a circulation chamber. The two circulation chambers are connected to the hot liquid tank and the cold liquid tank, respectively, to achieve liquid circulation. The side wall of the telescopic groove has a retractable sealing plate, and a sealing spring for driving the sealing plate to close is provided within the telescopic groove. The side wall of the sealing plate has a limit stop. When the circulating slider is pushed to the control valve chamber, the circulating slider closes the injection hole and simultaneously pushes the limit stop, connecting the circulation chamber with the control valve chamber. The hot liquid chamber is equipped with a heating pipe and a heating pump, and the cold liquid tank is equipped with a cooling pipe and a cooling pump.

[0015] By adopting the above technical solution, during use, the circulation slider slides under the operation of the heating pump or the cooling pump, causing the circulation slider to push the limit block to move, thereby making the circulation chamber circulate the liquid back and forth, improving the convenience of liquid flow. In addition, this design makes it easier to replace the liquid, reduces the mixing of hot and cold liquids, and ensures the stability of temperature changes in the temperature control seat.

[0016] Preferably, the circulating slider has guide ring grooves at both ends, and the guide ring grooves and the control valve cavity sidewall are formed with guide ring cavities, which are connected to the injection hole.

[0017] By adopting the above technical solution, the circulating slider abuts against the bottom of the control valve chamber during use. When it is necessary to switch between hot and cold liquids, the cooled liquid acts on the guide ring groove, which makes it easier to push the circulating slider and improves the stability of the circulating slider sliding.

[0018] Preferably, both the hot liquid tank and the cold liquid tank have liquid chambers. A baffle is provided in each liquid chamber. An outlet chamber and an inlet chamber are respectively formed on both sides of the baffle. The outlet chamber is connected to the injection hole, and the inlet chamber is connected to the circulation chamber. A limiting slide cavity for limiting the sliding distance of the baffle is provided on the side wall of the liquid chamber. Limiting slide plates are provided at both ends of the baffle and abut against the side wall of the liquid chamber. A float is provided on the top of the baffle near the inlet chamber. A connecting tension spring is provided at the bottom of the inlet chamber away from the baffle. The connecting tension spring is inclined upward and fixed to the baffle in the direction close to the baffle.

[0019] By adopting the above technical solution, during the process of liquid discharge, under the action of liquid pressure and connecting spring, the baffle can be moved closer to the inlet chamber, making the liquid height in the inlet and outlet chambers tend to be the same. As the liquid gradually circulates into the inlet chamber, under the action of liquid pressure, the baffle is pushed towards the outlet chamber. When cooling is nearly complete and the liquid height is high, the baffle can be driven to rise under the action of the float, thereby allowing the liquid in the inlet chamber to be discharged into the outlet chamber for subsequent liquid cooling or heating. This design allows for better cooling or heating of both hot and cold liquids and improves the convenience of liquid circulation.

[0020] Preferably, the sidewall of the limiting slide cavity has multiple guide grooves, which are opened along the sliding direction of the baffle. A guide sealing block is slidably connected in the guide groove. The multiple guide sealing blocks are integrally formed. A lifting groove is opened on the side of the guide sealing block near the baffle. The lifting groove is opened in the vertical direction.

[0021] By adopting the above technical solution, on the one hand, the baffle can be better sealed to ensure the sealing performance of the baffle, and on the other hand, the baffle can also slide in the lifting groove, so that the baffle can be raised and lowered more smoothly and more stably.

[0022] Preferably, a lifting spring is provided in the lifting groove, and the lifting spring is used to compress the baffle to descend.

[0023] By adopting the above technical solution, the baffle can be lowered more conveniently during use, improving the ease of use of the baffle.

[0024] Preferably, the side wall of the temperature control base is provided with multiple mounting holes, which are located in the gaps of the spirally arranged heat exchange chambers, and heating rods are inserted into the mounting holes.

[0025] By adopting the above technical solution and using an electric heating rod for heating, the temperature of the temperature control seat can be improved, thus ensuring the stability of the balloon formation in the product.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By adopting the above technical solution, when processing the balloon, firstly, the balloon mold is placed in the temperature control seat, then the balloon mold plug is clamped onto the plug fixing block for positioning. Subsequently, the first and second cylinders are activated to drive the temperature control seat and the plug fixing block to move towards each other. After the temperature control seat and the plug fixing block are aligned, the balloon blank to be processed is clamped, and a sealing ring is installed on the sealing block of the air inlet seat to ensure the sealing performance during balloon processing. After completing the above setup and adjustment, the entire balloon forming machine program is started, and the equipment enters the processing stage. High-temperature liquid, via the temperature control tube, provides the heat required for balloon forming during the balloon production process. After the balloon is formed, the equipment switches to the water cooling stage, where low-temperature liquid, via the temperature control tube, achieves rapid cooling of the processed balloon.

[0028] 2. During the balloon processing heating stage, the switch valve block inside the temperature control valve is pushed, so that the first and second high-temperature liquid passage holes on the switch valve block are precisely connected to the two temperature control tubes. The high-temperature liquid is transported to the temperature control seat through the temperature control tubes to provide the required heating temperature for balloon forming. After the balloon processing is completed, it enters the water cooling stage. The switch valve block is pulled to make the two high-temperature liquid passage holes staggered from the temperature control tubes. The switch valve block closes the upper liquid inlet chamber and the upper liquid outlet chamber to isolate and block the high-temperature liquid. The low-temperature liquid enters the first low-temperature liquid tank and is transported to the temperature control seat through the lower liquid inlet chamber. After heat exchange, the cooling water flows into the low-temperature circulation pipe through the drain hole, thereby realizing the rapid cooling of the processed balloon.

[0029] 3. During the processing of the balloon, the second and third driving components drive the corresponding screw transmission to achieve precise displacement adjustment of the air inlet seat and clamping seat. The transmission is stable and reliable with high positioning accuracy. It can adapt to the clamping and forming position adjustment requirements of different specifications of tube blanks in balloon processing, effectively improving the forming accuracy of the balloon and the stability of equipment operation.

[0041] This application discloses a balloon forming machine.

[0042] Example 1

[0043] Reference Figures 1-2A balloon molding machine includes a base 5, on which a sliding cavity 2 is provided. An air inlet seat 3 and a clamping seat 9 are slidably connected to both sides of the sliding cavity 2. A temperature control seat 7 is slidably connected between the air inlet seat 3 and the clamping seat 9.

The two temperature control tubes 13 are used to realize the circulation of hot and cold media in and out of the heat exchange cavity 6. A plug fixing block 8 for placing the balloon mold plug is slidably connected to the end of the temperature control seat 7 away from the air inlet seat 3. A second cylinder 10 for driving the plug fixing block 8 is installed in the sliding cavity 2. The second cylinder 10 is located on both sides of the clamping seat 9 and is symmetrically arranged.

[0044] Reference Figure 3The water supply assembly includes a high-temperature liquid tank 11 and a low-temperature liquid tank 25 fixed on the base 5. A temperature control valve 18 is mounted on the temperature control pipe 13. A switch valve block 17 is slidably connected inside the temperature control valve 18. The temperature control valve 18 is provided with a first driving member 16 for driving the switch valve block 17 to retract or extend. The switch valve block 17 has a first high-temperature liquid passage 15 and a second high-temperature liquid passage 14. One side of the temperature control valve 18 has a first temperature control valve chamber 12 and a second temperature control valve chamber 23 that communicate with the high-temperature liquid tank 11. The other side of the temperature control valve 18 has a third temperature control valve chamber 21 and a fourth temperature control valve chamber 22 that communicate with the temperature control base 7. When the switch valve block 17 retracts, the first high-temperature liquid passage 15... The two ends of the valve 5 are respectively connected to the first temperature control valve chamber 12 and the third temperature control valve chamber 21. The second high-temperature liquid passage 14 is respectively connected to the second temperature control valve chamber 23 and the fourth temperature control valve chamber 22. The switch valve block 17 has a first low-temperature liquid chamber 24 and a second low-temperature liquid chamber 19 connected to the low-temperature liquid tank 25. When the switch valve is pushed out, the first low-temperature liquid chamber 24 is connected to the fourth temperature control valve chamber 22; the second low-temperature liquid chamber 19 is connected to the third temperature control valve chamber 21. The side wall of the temperature control valve 18 has a drain hole 20 connected to the second low-temperature liquid chamber 19. A low-temperature circulation pipe is installed below the drain hole 20. One end of the low-temperature circulation pipe is connected to the drain hole 20, and the other end is connected to the low-temperature liquid tank 25. During the balloon processing heating stage, the switch valve block 17 inside the temperature control valve 18 is pushed, so that the first high-temperature liquid passage hole 15 and the second high-temperature liquid passage hole 14 on the switch valve block 17 are connected to each temperature control valve cavity. The high-temperature liquid is transported to the temperature control seat 7 through the temperature control pipe 13 to provide the required heating temperature for balloon forming. After the balloon processing is completed, it enters the water cooling stage. The switch valve block 17 is pulled to make the two high-temperature liquid passage holes staggered from each temperature control valve cavity. The switch valve block 17 closes the first temperature control valve cavity 12 and the second temperature control valve cavity 23 to achieve isolation and blockage from the high-temperature liquid. The low-temperature liquid enters the first low-temperature liquid tank and is transported to the temperature control seat 7 through the fourth temperature control cavity. The cooling water after heat exchange flows into the low-temperature circulation pipe through the drain hole 20, thereby realizing the rapid cooling operation of the processed balloon.

[0045] Both the air intake seat 3 and the clamping seat 9 have a fixed idler seat at their bottom. The idler seat has a sliding groove and an idler cavity inside, within which a screw for idler rotation is rotatably connected. Two screws are threadedly fitted with screw sleeves, which are fixed to the bottom of the air intake seat 3 and the clamping seat 9 respectively. Through the threaded transmission between the screws and screw sleeves, the air intake seat 3 and the clamping seat 9 are driven to perform horizontal reciprocating motion within the sliding groove. One end of each screw is connected to a third drive component and a second drive component, respectively, for driving the idler rotation of the two screws. During the balloon processing, the second and third drive components drive the corresponding screws, achieving precise displacement adjustment of the air intake seat 3 and the clamping seat 9. The transmission is stable and reliable, with high positioning accuracy, and can adapt to the clamping and forming position adjustment requirements of different specifications of tube blanks in balloon processing, effectively improving the balloon forming accuracy and equipment operational stability.

[0046] An air inlet is provided on the air inlet seat 3. The air inlet is used to inject nitrogen into the balloon blank that passes through the air inlet seat 3. A sealing block is installed on the air inlet seat 3. An annular sealing groove is provided on the surface of the sealing block for installing a sealing ring, thereby ensuring the airtightness of the balloon during the processing, thereby improving the accuracy of balloon forming and the quality of the finished product.

[0047] A jaw is rotatably connected to one side of the clamping seat 9. A cylindrical pad is installed at the clamping end of the jaw, and the clamping contact surface of the cylindrical pad has an inwardly concave corrugated structure. A rectangular pad is installed on the clamping seat 9 at the position corresponding to the cylindrical pad. The clamping contact surface of the rectangular pad is integrally formed with raised corrugations that match the inwardly concave corrugations of the cylindrical pad. The clamping contact surfaces of the rectangular pad and the cylindrical pad form an interlocking corrugated clamping structure. A drive cylinder is fixedly connected to the end of the jaw away from the cylindrical pad. The cylinder provides linear drive force, causing the jaw to rotate around the rotational connection point with the clamping seat 9, thereby achieving stable clamping and releasing of the balloon blank to be processed.

[0048] The implementation principle of a balloon forming machine according to an embodiment of this application is as follows: When processing balloons, firstly, the balloon mold is placed in the temperature control seat 7, and then the balloon mold plug is clamped onto the plug fixing block 8 for positioning. Subsequently, the first cylinder 4 and the second cylinder 10 are started to drive the temperature control seat 7 and the plug fixing block 8 to move towards each other. After the temperature control seat 7 and the plug fixing block 8 are aligned, the balloon blank to be processed is clamped, and a sealing ring is installed on the sealing block of the air inlet seat 3 to ensure the sealing performance during the balloon processing. After the above assembly and adjustment are completed, the entire program of the balloon forming machine is started, and the equipment enters the processing stage. During the heating process of the temperature control seat 7, the switch valve block 17 inside the temperature control valve 18 is pushed, so that the first high-temperature liquid passage hole 15 and the second high-temperature liquid passage hole 14 on the valve block are precisely connected with the two temperature control tubes 13. The high-temperature liquid is transported to the interior of the temperature control seat 7 through the temperature control tubes 13 to provide the heating temperature required for the balloon forming process. When the temperature inside the temperature control seat 7 reaches the balloon forming process set value, nitrogen gas required for balloon forming is introduced into the temperature control seat 7 through the air inlet seat 3, so that the center position of the balloon blank is inflated and bulged to form the balloon forming outline. After the balloon is formed, the equipment switches to the water cooling stage. The switch valve block 17 is pulled to separate the two high-temperature liquid passage holes from each temperature control valve cavity. The switch valve block 17 closes the first temperature control valve cavity 12 and the second temperature control valve cavity 23, realizing the isolation and blockage between the temperature control seat 7 and the high-temperature liquid pipeline. At this time, the cryogenic liquid enters the first cryogenic liquid tank and is transported to the temperature control seat 7 through the fourth temperature control chamber. After heat exchange, the cooling water flows into the cryogenic circulation pipe through the drain hole 20, thereby realizing the rapid cooling operation of the processed balloon.

[0049] Example 2

[0050] Reference Figure 4The difference between this embodiment and Embodiment 1 is that the water supply assembly includes a control valve block 38, a hot liquid tank 28, and a cold liquid tank 32. The control valve block 38 has a control valve chamber 26 connected to two temperature control pipes 13. The side walls of the two control valve chambers 26 have injection holes 31 connected to the hot liquid tank 28 and the cold liquid tank 32, respectively. The heat exchange chamber 6 is spirally arranged, and a circulating slider 34 is slidably connected within the heat exchange chamber 6. The circulating slider 34 slides within the temperature control pipes 13 and the control valve chamber 26. The side wall of the control valve chamber 26 has a telescopic groove 36, and the bottom of the telescopic groove 36 has a circulation chamber 30. Two circulation... The cavity 30 is connected to the hot liquid tank 28 and the cold liquid tank 32 respectively, for realizing the circulation of liquid. The side wall of the telescopic groove 36 is equipped with a sealing plate 35, and a sealing spring 37 is provided in the telescopic groove 36 to drive the sealing plate 35 to close. The side wall of the sealing plate 35 is provided with a limit stop 29. When the circulation slider 34 is pushed to the control valve cavity 26, the circulation slider 34 closes the liquid injection hole 31, and at the same time pushes the limit stop 29 to connect the circulation cavity 30 with the control valve cavity 26. The hot liquid tank 28 is equipped with a heating pipe 27 and a heating pump 52, and the cold liquid tank 32 is equipped with a cooling pipe 33 and a cooling pump 53. In use, under the operation of the heating pump 52 or the cooling pump 53, the circulation slider 34 slides, and the circulation slider 34 pushes the limit stop 29 to move, so that the circulation cavity 30 circulates the liquid back and forth, improving the convenience of liquid flow. With this design, it is easier to replace the liquid, reduce the mixing of hot and cold liquids, and ensure the stability of temperature changes in the temperature control seat 7.

[0051] Reference Figure 5 The circulating slider 34 has guide ring grooves 54 at both ends, and guide ring grooves 54 and guide ring cavities 55 are formed on the side wall of the control valve cavity 26. The guide ring cavities 55 are connected to the injection hole 31. During use, the circulating slider 34 abuts against the bottom of the control valve cavity 26. When it is necessary to switch between hot and cold liquids, the cooled liquid acts on the guide ring grooves 54, which makes it easier to push the circulating slider 34 and improves the stability of the sliding of the circulating slider 34.

[0052] Reference Figures 6-7Both the hot liquid tank 28 and the cold liquid tank 32 have liquid chambers. A baffle 39 is installed within each liquid chamber. An outlet chamber 44 and an inlet chamber 45 are formed on either side of the baffle 39. The outlet chamber 44 is connected to the injection hole 31, and the inlet chamber 45 is connected to the circulation chamber 30. A limiting slide cavity 43 is provided on the side wall of the liquid chamber to limit the sliding distance of the baffle 39. Limiting slide plates 41 are provided at both ends of the baffle 39, abutting against the side wall of the liquid chamber. A float 40 is provided on the top of the baffle 39 near the inlet chamber 45. A connecting tension spring 42 is provided at the bottom of the inlet chamber 45 away from the baffle 39, and the connecting tension spring 42 is inclined upwards and fixed to the baffle 39 in the direction close to it. During use, when the liquid is discharged… Under the action of liquid pressure and connecting spring 42, the baffle 39 can move closer to the liquid inlet chamber 45, so that the liquid height of the liquid inlet chamber 45 and the liquid outlet chamber 44 tend to be the same. When the liquid gradually circulates into the liquid inlet chamber 45, under the action of liquid pressure, the baffle 39 is pushed towards the liquid outlet chamber 44. When the cooling is almost complete and the liquid height is high, the baffle 39 can be driven to float up under the action of float 40, so that the liquid in the liquid inlet chamber 45 can be discharged into the liquid outlet chamber 44 for subsequent liquid cooling or heating. With this design, the two liquids, hot and cold, can be cooled or heated more effectively, and the convenience of liquid circulation can be improved.

[0053] Reference Figure 8 Multiple guide grooves 46 are formed at the bottom of the liquid chamber, and these grooves 46 are opened along the sliding direction of the baffle 39. Guide sealing blocks 47 are slidably connected within the guide grooves 46. These guide sealing blocks 47 are integrally formed, and a lifting groove 48 is formed on the side of each guide sealing block 47 near the baffle 39, and the lifting groove 48 is opened vertically. This design allows the baffle 39 to better seal, ensuring its airtightness. Furthermore, the baffle 39 can slide within the lifting groove 48, allowing for smoother and more stable lifting and sliding.

[0054] A lifting spring 49 is provided in the lifting groove 48. The lifting spring 49 is used to squeeze the baffle 39 down, thereby improving the ease of use of the baffle 39.

[0055] Reference Figure 9 The side wall of the temperature control base 7 is provided with multiple mounting holes 50. The mounting holes 50 are located in the gaps of the spirally arranged heat exchange chambers 6. An electric heating rod 51 is inserted into the mounting hole 50. The electric heating rod 51 is used for heating, which can better improve the temperature of the temperature control base 7 and ensure the stability of the product forming a balloon.

[0056] The implementation principle of Example 2 is as follows: During operation, the heating pump 52 or the cooling pump 53 drives the corresponding liquid into the control valve chamber 26, pushing the circulation slider 34 to slide within the temperature control tube 13 and the control valve chamber 26. During the movement of the circulation slider 34, the corresponding injection hole 31 is closed, and at the same time, the limit block 29 is pushed to compress the sealing plate 35 and the sealing spring 37, thereby opening the circulation chamber 30, allowing the hot or cold liquid to form a closed loop circulation along the preset pipeline, avoiding the mixing of hot and cold liquids, ensuring stable temperature switching of the temperature control seat 7, and achieving precise temperature adjustment of the temperature control seat 7. The liquid levels in the outlet chamber 44 and inlet chamber 45 can be balanced within the hot liquid tank 28 or cold liquid tank 32 via a baffle 39, a float 40, and a tension spring. When liquid is discharged, the baffle 39 moves towards the inlet chamber 45 under pressure and the tension spring. When liquid flows back, the liquid level in the inlet chamber 45 rises, causing the float 40 to lift the baffle 39, allowing the liquid in the inlet chamber 45 to flow into the outlet chamber 44 for subsequent cooling or heating. This design allows for better cooling or heating of both hot and cold liquids, improving the convenience of liquid circulation. The guide sealing block 47 and the lifting spring 49 at the bottom of the liquid chamber further ensure smooth sliding of the baffle 39 and reliable sealing, reducing the risk of leakage. The temperature control seat 7 and the heat exchange chamber 6 adopt a spiral arrangement to increase the heat exchange area. With the electric heating rod 51 installed in the gap of the heat exchange chamber 6, heat can be quickly replenished and the temperature control effect can be enhanced. Ultimately, the temperature of the temperature control seat 7 can be accurately and stably controlled, providing a stable temperature environment for balloon molding.

[0057] By adopting this technical solution, labor costs can be significantly reduced; at the same time, the integrated design of the heating and cooling devices can minimize the reduction in the forming accuracy of the balloon blank caused by improper manual operation or environmental interference, effectively ensuring the processing quality and precision stability of the balloon.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
