Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a synchronous lifting latex balloon molding device. Background Technology

[0002] In the field of medical devices, latex balloon molding devices manufacture precision medical latex balloon products through a mold impregnation process. The core requirement of this process is that the lifting and lowering movement of the mold during the impregnation process must remain highly stable.

[0003] In the existing technology, latex balloon molding devices mainly use a motor-driven single screw structure or hydraulic cylinder to realize the mold lifting movement, and control the impregnation time through mechanical limit devices or simple timers.

[0004] However, the motor-driven single-screw structure is prone to uneven loading due to concentrated force, causing torsional vibration and nonlinear shaking of the lifting platform; the hydraulic system, due to fluid compressibility and valve response delay, experiences step-like shaking caused by pressure pulsation during the lifting process; insufficient rigidity of moving parts further amplifies the vibration amplitude and exacerbates mold shaking. These shaking directly cause wavy patterns on the balloon surface, resulting in uneven latex adhesion and affecting the balloon's functionality and sealing performance. Utility Model Content

Detailed Implementation

[0030] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0031] In the field of latex balloon production, existing balloon molding devices often suffer from unstable lifting and insufficient time control precision. These devices typically employ a single-screw drive or a lifting structure powered by a common motor, which is prone to vibration during mold lifting, resulting in wavy patterns on the balloon surface. Simultaneously, the lack of a precise time control mechanism makes it difficult to accurately control the mold's residence time in the latex liquid, leading to uneven balloon thickness and impacting product quality and production efficiency.

[0032] To address the aforementioned problems, this application provides a synchronous lifting latex balloon molding device.

[0033] The following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0034] In some embodiments, see Figure 1 and Figure 2 The support frame 1 is the basic load-bearing structure of the entire device, used to install and fix all components such as the drive mechanism, transmission mechanism, lifting mechanism, and latex tank. The support frame 1 ensures that each part maintains a relatively stable positional relationship during operation.

[0035] The drive mechanism 2 is the power source of the device, providing driving force for the entire lifting process. The drive motor 21, as the core power component, provides the power output for rotational motion. The drive wheel 22 is fixedly connected to the output shaft of the drive motor 21 and rotates synchronously with the drive motor 21. Through cooperation with the transmission mechanism 3, it transmits power, realizing the transfer and conversion of power.

[0036] The transmission mechanism 3 serves to transmit power and achieve synchronous motion, connecting the drive mechanism 2 and the lifting mechanism 4. The synchronous belt 31 meshes with the drive wheel 22, accurately transmitting the rotational motion of the drive wheel 22 to the first driven wheel 32 and the second driven wheel 33, ensuring the stability and accuracy of power transmission. The first driven wheel 32 and the second driven wheel 33 mesh with the synchronous belt 31, rotating synchronously under its drive, which in turn drives the first ball screw 34 and the second ball screw 35, which are fixedly connected to it, to rotate. The first ball screw 34 and the second ball screw 35 are rotatably supported on the support frame 1 and are parallel to each other. They convert rotational motion into linear motion, achieving the lifting and lowering of the mold 6 through cooperation with the lifting mechanism 4. The first end of the first ball screw 34 is fixedly connected to the first driven wheel 32, and the first end of the second ball screw 35 is fixedly connected to the second driven wheel 33, so that when the driven wheel rotates, the ball screws can rotate synchronously.

[0037] The lifting mechanism 4 is the direct actuator for lifting the mold 6. The lifting mechanism 4 drives the mold 6 to reciprocate along the axis of the first ball screw 34 and the second ball screw 35 from its initial position to the inner bottom groove of the latex tank 5. The first side of the column synchronization plate 41 is fixedly connected to the ball nut of the first ball screw 34, and the second side of the column synchronization plate 41 is fixedly connected to the ball nut of the second ball screw 35. When the ball screws rotate, the ball nuts drive the column synchronization plate 41 to move linearly, thereby achieving synchronous lifting. The column assembly 42 consists of four columns. The first end of the column assembly 42 is fixedly mounted on the column synchronization plate 41 and can move together with the column synchronization plate 41, providing support and connection for the bracket 43. The bracket 43 is fixedly connected to the second end of the column assembly 42 and is used to place the mold 6, transmitting the movement of the column assembly 42 to the mold 6, causing the mold 6 to rise and fall together with the bracket.

[0038] The latex tank 5 is fixedly mounted on the support frame 1 via the latex tank support plate 51, located between the column synchronization plate 41 and the bracket 43, and is used to hold latex liquid to provide the necessary material for the mold 6 to be dipped in latex.

[0039] The mold 6 is mounted on the support 43. The mold 6 reciprocates from its initial position to the inner bottom groove of the latex tank 5 along the axial direction of the first ball screw 34 and the second ball screw 35. The mold 6 forms the balloon by immersing itself in the latex liquid in the latex tank 5.

[0040] It is understood that the synchronous lifting latex balloon molding device of this embodiment operates by the coordinated work of various components to achieve the smooth lifting of the mold and complete the impregnation process to form a latex balloon.

[0041] It should be noted that before starting the device, an appropriate amount of latex liquid needs to be injected into the latex tank 5. The operator places the mold 6 that meets the specifications on the support 43, ensuring that the mold 6 is installed firmly to prevent shaking or falling off during the lifting process.

[0042] It should be noted that when the device is started, the drive mechanism 2 begins to work. The drive motor 21 is energized and rotates, and the output shaft of the drive motor 21 drives the drive wheel 22, which is fixedly connected to it, to rotate synchronously. Since the drive wheel 22 meshes with the synchronous belt 31, the rotation of the drive wheel 22 will drive the synchronous belt 31 to move. The synchronous belt 31 also meshes with the first driven wheel 32 and the second driven wheel 33. Under the drive of the synchronous belt 31, the first driven wheel 32 and the second driven wheel 33 also rotate synchronously.

[0043] As the first driven wheel 32 and the second driven wheel 33 rotate, the first ball screw 34 and the second ball screw 35, which are fixedly connected to the first driven wheel 32 and the second driven wheel 33 respectively, begin to rotate. Since the first ball screw 34 and the second ball screw 35 are parallel to each other and rotatably supported on the support frame 1, their rotation causes the ball nuts fitted on them to move linearly. Since both sides of the column synchronization plate 41 are fixedly connected to the ball nuts of the first ball screw 34 and the second ball screw 35 respectively, the linear movement of the ball nuts drives the column synchronization plate 41 to move up and down along the axis of the ball screws.

[0044] The movement of the column synchronization plate 41 is transmitted to the column assembly 42 fixed on it, and the four columns rise and fall together with the column synchronization plate 41. Since the bracket 43 is fixedly connected to the other end of the column assembly 42, the bracket 43 will drive the mold 6 placed on it to move synchronously. At this time, the mold 6 reciprocates from the initial position to the inner bottom groove of the latex tank 5 along the axial direction of the first ball screw 34 and the second ball screw 35. When the mold 6 descends, it will gradually be immersed in the latex liquid in the latex tank, and the latex liquid will be evenly attached to the surface of the mold 6; when the mold 6 rises, it will detach from the latex liquid, completing one dipping process.

[0045] Throughout the operation, the use of synchronous belt 31 and dual ball screw drive ensures the synchronous rotation of the first ball screw 34 and the second ball screw 35, thereby ensuring the smooth lifting and lowering of the column synchronous plate 41 and preventing the mold 6 from shaking during the lifting process. Simultaneously, by controlling the running time of the drive motor 21, the immersion time of the mold 6 in the latex liquid can be controlled, thus achieving control over the thickness of the balloon.

[0046] The device employs a drive motor 21 that, via a synchronous belt 31, drives the first driven wheel 32 and the second driven wheel 33 to rotate synchronously. This, in turn, drives the parallel first ball screw 34 and the second ball screw 35 to move synchronously, enabling the column synchronous plate 41 to rise and fall smoothly and preventing the mold 6 from vibrating during the lifting process. This ensures that the latex liquid adheres evenly to the mold surface, reducing the possibility of defects such as wavy patterns caused by vibration and improving product quality.

[0047] In some embodiments, see Figure 2 Panel 7 is an important structural component in the synchronous lifting latex balloon molding device. It is fixedly installed at the top of the support frame 1 and located below the bracket 43. Panel 7 is usually made of high-strength metal sheet with sufficient thickness and hardness to withstand the lateral force and impact force generated by the column assembly 42 during the lifting process, thus avoiding deformation due to force affecting the operating accuracy of the device.

[0048] A through hole is provided in the center area of ​​panel 7. The size of the through hole is slightly larger than the cross-sectional size of the latex tank 5. The latex tank 5 passes through the through hole, so that the latex tank 5 forms a stable support at panel 7, and at the same time provides space for the mold 6 to pass through panel 7 and enter the latex tank 5.

[0049] The panel 7 is provided with guide holes that cooperate with the column assembly 42. The number and position of the guide holes correspond one-to-one with the number and arrangement of the columns in the column assembly 42. When the column passes through the guide hole, the guide hole restricts the radial swing of the column and provides guidance for the column to rise and fall.

[0050] It should be noted that panel 7 enhances the stability of the column assembly 42's movement. The guide hole's constraint on the column ensures that the column can only move along the axial direction of the first ball screw 34 and the second ball screw 35, effectively limiting the column's displacement in the radial direction, reducing the vibration of the mold 6 caused by the column's shaking, ensuring the relative position of the mold 6 and the latex liquid is stable during the impregnation process, and further guaranteeing the quality of the balloon molding.

[0051] In some embodiments, see Figure 2 The drive wheel 22 is a synchronous belt pulley, and its outer circumference is provided with teeth that match those of the synchronous belt 31. The tooth profile and tooth pitch are perfectly matched with the teeth of the synchronous belt 31, enabling precise meshing. The main function of the drive wheel 22 is to transmit the rotational power of the drive motor 21 through meshing with the synchronous belt 31, ensuring no slippage during power transmission and guaranteeing the accuracy of transmission.

[0052] The first driven pulley 32 is a synchronous belt pulley. Teeth that mesh with the synchronous belt 31 are provided on the outer circumference of the first driven pulley 32. The tooth profile parameters are consistent with those of the drive pulley 22 and the synchronous belt 31 to achieve precise coordination among the three. The first driven pulley 32 is fixedly mounted on the first end of the first ball screw 34 and rotates synchronously with the first ball screw 34. The function of the first driven pulley 32 is to receive the power transmitted by the synchronous belt 31 and convert the power into the rotational motion of the first ball screw 34. Simultaneously, through meshing with the synchronous belt 31, it ensures its own synchronous rotation with the drive pulley 22 and the second driven pulley 33.

[0053] The second driven pulley 33 is a synchronous belt pulley. Teeth that mesh with the synchronous belt 31 are provided on the outer circumference of the second driven pulley 33. The tooth profile parameters are consistent with those of the drive pulley 22, the synchronous belt 31, and the first driven pulley 32, ensuring that it can maintain the same rotational speed and direction of rotation as the first driven pulley 32 under the drive of the synchronous belt 31. The second driven pulley 33 is fixedly connected to the first end of the second ball screw 35, forming an integral rotating structure with the second ball screw 35. The function of the second driven pulley 33 is to obtain the power transmitted by the drive pulley 22 through the synchronous belt 31, driving the second ball screw 35 to rotate. Due to its synchronicity with the first driven pulley 32, it ensures that the rotational movements of the second ball screw 35 and the first ball screw 34 are completely synchronized.

[0054] Understandably, after the device is started, the drive motor 21 begins to operate, and the output shaft of the drive motor 21 drives the drive wheel 22 to rotate. Because the teeth of the drive wheel 22 precisely mesh with the teeth of the synchronous belt 31, the rotational force of the drive wheel 22 is transmitted to the synchronous belt 31 through the teeth, causing the synchronous belt 31 to move along a preset trajectory. During the movement of the synchronous belt 31, its teeth continuously mesh with the teeth of the first driven wheel 32 and the second driven wheel 33. Because the tooth parameters of the three are identical, the movement of the synchronous belt 31 drives the first driven wheel 32 and the second driven wheel 33 to rotate synchronously at the same speed as the drive wheel 22, and in the same direction.

[0055] When the first driven wheel 32 rotates, it directly drives the first ball screw 34, which is fixedly connected to it, to rotate. The second driven wheel 33 rotates synchronously, driving the second ball screw 35 to rotate at the same speed and direction. Since the first ball screw 34 and the second ball screw 35 are parallel to each other and rotate synchronously, the ball nuts on their surfaces make completely synchronous linear movements along the screw axis, thereby pushing the column synchronous plate 41 to rise and fall smoothly.

[0056] The movement of the column synchronization plate 41 is transmitted to the column assembly 42, and the four columns drive the bracket 43 and the mold 6 to rise and fall synchronously. During this process, since the drive wheel 22, the first driven wheel 32, and the second driven wheel 33 are all synchronous belt pulleys, the slippage problem that may occur in traditional belt drive is effectively avoided, ensuring that the rotation of the first ball screw 34 and the second ball screw 35 always remains highly consistent. The force on both sides of the column synchronization plate 41 is uniform, without tilting or shaking, and the mold 6 can move in a stable straight line.

[0057] In some embodiments, see Figure 2 The first ball screw 34 and the second ball screw 35 are symmetrically distributed on both sides of the output shaft axis of the drive motor 21. This distribution is based on the overall force balance design of the device. The distance between their axes and the output shaft axis of the drive motor 21 is equal, and they are symmetrically arranged in the same horizontal plane. They maintain identical specifications, including length, diameter, and thread pitch, to ensure that they can withstand uniform loads during transmission and avoid tilting or vibration caused by uneven force. The core function of this symmetrical distribution is to ensure that the power transmitted by the drive motor 21 through the synchronous belt 31 is evenly distributed to the two ball screws, ensuring that their rotational movements are completely synchronized, thus providing a foundation for the smooth operation of the lifting mechanism 4.

[0058] The first ball screw fixing block 36 is a structural component used to fix the end of the first ball screw 34. The first ball screw fixing block 36 is fixedly installed on the side wall of the support frame 1 by bolts or other connecting parts. The first ball screw fixing block 36 has a mounting hole that matches the first end of the first ball screw 34. The first end of the first ball screw 34 passes through the mounting hole and is fixedly connected to the first driven wheel 32. The mounting hole is usually equipped with a bearing, so that the first ball screw 34 can rotate flexibly under the constraint of the first ball screw fixing block 36, while limiting its axial displacement and ensuring that the rotation center axis of the first ball screw 34 remains fixed.

[0059] The second ball screw fixing block 37 has the same structure and function as the first ball screw fixing block 36, except that its installation position corresponds to the second ball screw 35. The second ball screw fixing block 37 is also fixed on the side wall of the support frame 1. The second ball screw fixing block 37 and the first ball screw fixing block 36 are symmetrically distributed about the output shaft axis of the drive motor 21. The internal mounting hole of the second ball screw fixing block 37 is adapted to the first end of the second ball screw 35. The bearing supports and constrains the first end of the second ball screw 35, ensuring that the second ball screw 35 can rotate stably and its axial position is fixed, maintaining parallelism and symmetry with the first ball screw 34.

[0060] The second ends of the first ball screw 34 and the second ball screw 35 are supported on the inner wall of the panel 7 by bearings. The outer ring of the bearing is fixedly connected to the inner wall of the panel 7, and the inner ring is interference-fitted with the second end of the ball screw, so that the second end of the ball screw can rotate flexibly under the action of the bearing, while constraining the movement trajectory of the ball screw, ensuring that the axes of the two ball screws always remain parallel and fixed, and avoiding the impact of end shaking on the transmission accuracy.

[0061] It should be noted that during the rotation of the first ball screw 34, its first end is constrained by the first ball screw fixing block 36: the first ball screw fixing block 36 restricts the axial displacement of the first ball screw 34 through an internal bearing, while allowing the first ball screw 34 to rotate freely, so that the first end of the screw always rotates around a fixed axis; the second end of the first ball screw 34 is supported on the inner wall of the panel 7 by a bearing, and the bearing transmits the radial force generated by the rotation of the screw to the panel 7, further fixing the rotation center of the screw and preventing end wobbling. Similarly, the second ball screw 35 also maintains a stable rotation state under the action of the second ball screw fixing block 37 and the bearing on the inner wall of the panel 7, and due to the symmetrical distribution and the same constraint method as the first ball screw 34, the rotational accuracy and synchronization of the two are fully guaranteed.

[0062] The first ball screw 34 and the second ball screw 35 are symmetrically distributed on both sides of the output shaft axis of the drive motor 21, so that the power transmitted by the synchronous belt 31 can be evenly distributed to the two screws. The load on both is exactly the same, avoiding tilting or vibration caused by excessive force on one side. The first ball screw fixing block 36 and the second ball screw fixing block 37 respectively fix and constrain the first end of the two screws, and the bearing on the inner wall of the panel 7 supports the second end of the screws, limiting the radial and axial displacement of the screws during rotation. This ensures that the axes of the two screws always remain parallel and fixed, eliminating the problem of mold 6 shaking caused by screw wobbling, ensuring the uniform adhesion of latex liquid on the surface of mold 6, and solving the technical problem of wavy patterns easily generated on the surface of the balloon.

[0063] In some embodiments, see Figure 2 The column assembly 42 is rectangularly distributed in the four corner areas of the column synchronization plate 41; the first end of the column assembly 42 is fixedly mounted on the column synchronization plate 41 by a positioning pin 44.

[0064] Understandably, since the column assembly 42 is rectangularly distributed at the four corners of the column synchronization plate 41, when the column synchronization plate 41 is raised and lowered, the four columns can evenly distribute the weight of the bracket 43 and the mold 6 from the four corners, thus balancing the force on the column synchronization plate 41 and avoiding local deformation or tilting caused by concentrated force. At the same time, the positioning pin 44 firmly connects the first end of the column assembly 42 to the column synchronization plate 41. The fixing function of the positioning pin 44 ensures the rigid connection between the column and the column synchronization plate 41, eliminating relative movement between the two, making the movement of the column assembly 42 more stable, structurally reducing the vibration during the raising and lowering of the mold 6, and ensuring the smoothness of the impregnation process.

[0065] In some embodiments, see Figure 2 A linear bearing 8 is installed inside the guide hole. The column passes through the corresponding linear bearing 8 and reciprocates along the axis of the first ball screw 34 and the second ball screw 35 within the corresponding linear bearing 8. The inner ring of the linear bearing 8 is tightly fitted to the outer surface of the column, while the outer ring is fixed to the inner wall of the guide hole.

[0066] It should be noted that the linear bearing 8 reduces the frictional resistance during the movement of the column. The linear bearing 8 converts the sliding friction between the column and the panel 7 into rolling friction, which greatly reduces the movement resistance and makes the lifting and lowering of the column smoother. The linear bearing 8 also reduces the vibration of the mold 6 and alleviates defects such as wavy patterns on the surface of the latex ball bearing caused by vibration.

[0067] In some embodiments, see Figure 2 The drive motor 21 is a servo motor, which is a type of motor capable of precisely controlling speed and position. A servo motor adjusts its operating state by receiving pulse signals from the controller, and features stable speed, fast response, and high control precision. In this device, a servo motor is selected as the drive motor 21 to precisely control its rotation angle and time, thereby precisely adjusting the lifting height, speed, and dwell time of the mold 6 within the latex tank 5, meeting the time and motion precision requirements of latex balloon molding.

[0068] The drive motor 21 is mounted on the support frame 1 via a shock-absorbing base 9. The shock-absorbing base 9 is typically made of an elastic material, and its structure can absorb and buffer the vibrations generated by the drive motor 21 during operation. One end of the shock-absorbing base 9 is fixedly connected to the drive motor 21, and the other end is fixed to the support frame 1, transforming the rigid connection between the drive motor 21 and the support frame 1 into an elastic connection, thereby reducing the transmission of vibrations from the drive motor 21 to the support frame 1 and other components of the device.

[0069] The output of controller 10 is connected to the input of drive motor 21. Controller 10 is the control core of the entire device and can be a PLC or microprocessor with built-in preset programs and parameter adjustment interface. Operators set parameters such as lifting height, speed, and impregnation time of mold 6 through controller 10. Controller 10 converts the parameters into electrical signals and sends them to drive motor 21 to control its start, stop, speed, and rotation direction, thereby realizing automated control of the entire molding process.

[0070] It should be noted that after the device is started, the controller 10 sends an electrical signal to the drive motor 21 according to preset parameters. Upon receiving the signal, the drive motor 21 starts, and its output shaft drives the drive wheel 22 to rotate. Since the drive motor 21 is a servo motor, it can rotate strictly according to the speed set by the controller 10, and the internal feedback device corrects deviations in real time, ensuring the accuracy of the rotation angle and speed. For example, when the mold 6 needs to descend at a specific speed, the controller 5 sends a pulse signal of the corresponding frequency, and the speed of the drive motor 21 matches accordingly, making the rotation of the drive wheel 22 stable and controllable.

[0071] Under the control of the controller 10, the servo motor can precisely execute lifting speed, position, and time commands, ensuring that the depth and dwell time of the mold 6 are completely consistent each time it is dipped in the adhesive. This solves the problem of uneven balloon thickness caused by insufficient precision of traditional motor control, resulting in uniform product specifications, a significantly improved pass rate, and precise control of the molding process. The shock-absorbing base 9 effectively absorbs the vibration of the drive motor 21, reducing the impact of vibration on the transmission and lifting mechanisms, preventing shaking during the lifting of the mold 6, ensuring the stability of the operation, preventing wavy patterns on the balloon surface, and improving product quality and molding stability.

[0072] In some embodiments, the protective cover 11 is fixedly mounted on the support frame 1. The protective cover 11 is made of metal sheet or high-strength plastic, possessing a certain structural strength to resist external impacts or foreign object intrusion. The shape and size of the protective cover 11 are designed according to the layout of the drive motor 21, ensuring that it completely covers the exterior of the drive motor 21. Openings or clearance grooves are reserved at the positions where the synchronous belt 31 meshes with the drive wheel 22 to ensure normal meshing and transmission between the synchronous belt 31 and the drive wheel 22. At the same time, necessary heat dissipation gaps or ventilation openings are reserved to prevent the performance of the drive mechanism 2 from being affected by poor heat dissipation during operation.

[0073] The protective cover 11 reduces the impact of the external environment on the drive wheel 22, prevents latex splashes from corroding the drive motor 21, ensures the performance stability of the drive mechanism 2, and indirectly ensures the accuracy of the lifting and lowering movement of the mold 6.
