Description

Technical Field

[0001] This application relates to the field of foaming equipment technology, and in particular to a rotary foaming machine production line. Background Technology

[0002] As a key component for improving riding comfort, the quality of the foam filling inside the motorcycle seat directly affects the user experience. Currently, most motorcycle seat manufacturers in the industry generally use rotary foam machines to produce the foam needed for motorcycle seat fillings.

[0003] Existing rotary foaming machine production lines typically consist of a rotary table and a foaming machine. The foaming machine is fixed to one side of the rotary table, on which multiple foaming mold frames are evenly arranged. The specific production process is as follows: The rotary table rotates under the drive of a bottom-mounted geared motor, causing the multiple foaming mold frames to move sequentially along a preset trajectory. When a foaming mold frame moves to the injection station of the foaming machine, the worker operates the injection gun on the foaming machine to precisely pour the foaming material into the mold cavity installed in the foaming mold frame. After the injection operation is completed, the rotary table continues to drive the foaming mold frame to rotate, causing it to pass sequentially through the curing station, workpiece removal station, mold cleaning station, and release agent spraying station, thus forming a complete sponge production process.

[0004] However, existing turntables typically operate in a continuous rotation mode. During the process of manually operating the injection gun to pour raw materials for a long time, it is easy to feel tired due to physical exertion. This fatigue not only leads to a decrease in operating speed, but also affects the accuracy and filling amount of raw materials. Consequently, it is inevitable that the foaming agent will not be filled enough in the foaming mold cavity, thus affecting the quality of the sponge and presenting obvious shortcomings. Utility Model Content

[0005] To improve the production quality of sponges, this application provides a rotary foaming machine production line.

[0006] The rotary foaming machine production line provided in this application adopts the following technical solution: A rotary foaming machine production line includes a workbench with a turntable rotatably connected thereon. Multiple foaming mold frames are evenly arranged circumferentially on the turntable. A groove is formed within the workbench, and an intermittent rotation assembly is disposed within the groove. The intermittent rotation assembly includes a grooved wheel coaxially arranged with the turntable. The grooved wheel has equally spaced slots corresponding to the multiple foaming mold frames. A dial is rotatably connected within the groove, and the dial has pins that mesh with the equally spaced slots. The dial has the same curvature as the grooved wheel. A drive assembly for rotating the dial is disposed within the groove.

[0007] By adopting the above technical solution, during foaming, the drive component drives the dial to rotate, and the dial drives the pin to revolve around the center of the dial. When the pin rotates to align with one of the equal slots, the pin embeds into the slot and generates a driving force on the slot wall. The pin pushes the groove wheel and the turntable to rotate synchronously, thereby making the foaming mold frame gradually approach the injection station. When the pin moves to the bottom of the equal slot, as the dial continues to rotate, the pin gradually disengages from the slot. At this time, the groove wheel loses the driving force of the pin and stops rotating. At the same time, the arc surface of the dial will closely fit with the outer arc surface of the groove wheel to form a positioning constraint, preventing the groove wheel from continuing to rotate under inertia. The turntable also stops, and at this time, one foaming mold frame is stationed at the injection station, providing a stable and sufficient operating time for manual operation of the injection gun to pour raw materials. The intermittent rotation component realizes the intermittent rotation of the turntable, reducing the probability of insufficient foaming due to worker fatigue, thereby improving the production quality of the sponge.

[0008] Optionally, the drive assembly includes a drive motor and a reduction gearbox, the output shaft of the drive motor is connected to the input end of the reduction gearbox, and the output end of the reduction gearbox is coaxially connected to the rotation shaft of the dial.

[0009] By adopting the above technical solution, during the foaming production process, the power of the drive motor is transmitted to the reduction gearbox. After being reduced and amplified by the reduction gearbox, the power is transmitted to the dial, thereby realizing the intermittent rotation of the turntable. Since the reduction gearbox has the functions of power reduction and torque amplification, it can convert the high-speed, low-torque power output by the drive motor into the low-speed, high-torque power required for the rotation of the dial, avoiding the dial from rotating too fast due to excessive power speed, thus further extending the intermittent time of the turntable rotation, while ensuring the smoothness of power transmission.

[0010] Optionally, the worktable is provided with a movable annular groove, which is located on the outer periphery of the groove, and the bottom surface of the turntable is provided with a roller that slides in cooperation with the movable annular groove.

[0011] By adopting the above technical solution, the movable ring groove provides guidance for the rotation of the turntable, reducing the possibility of eccentric offset when the turntable rotates, thereby ensuring that the foaming mold frame moves to the work station. At the same time, through the cooperation of the roller and the movable ring groove, the sliding friction between the turntable and the worktable is converted into the rolling friction of the roller, reducing the friction coefficient between the two, reducing the direct wear between the bottom surface of the turntable and the surface of the worktable, and extending the service life of the turntable and the worktable.

[0012] Optionally, the bottom of the foaming mold frame is provided with multiple mounting columns, and the turntable is provided with mounting grooves that slide and cooperate with the multiple mounting columns. The turntable is provided with assembly components that correspond one-to-one with the multiple foaming mold frames. The assembly components drive the mounting columns to be fastened or movably disposed inside the mounting grooves.

[0013] By adopting the above technical solution, the assembly components enable the detachable connection of the foaming mold frame on the turntable. When the foaming mold frame is damaged or needs to be replaced with another model, the worker only needs to release the locking state of the mounting column through the assembly components, and then the foaming mold frame can be loosely removed from the turntable along the mounting groove. This eliminates the need to disassemble a large number of bolts and other connecting parts, shortens the maintenance and replacement time of the foaming mold frame, and reduces the downtime of the production line due to mold frame maintenance.

[0014] Optionally, the assembly component includes a threaded post, a rotating groove on the turntable that rotatably engages with the threaded post, a connecting ring threadedly connected to the threaded post, a connecting rod hinged to the connecting ring corresponding to a plurality of mounting posts, a plug-in plate hinged to the end of the connecting rod away from the connecting ring, a limiting groove on the turntable that slidably engages with the plug-in plate, the limiting groove being parallel to the radial direction of the threaded post, and a plug-in groove on each mounting post that engages with the plug-in plate.

[0015] By adopting the above technical solution, the worker can rotate the threaded column in the forward or reverse direction. Under the guidance and limitation of the limiting groove, the threaded column drives the connecting ring to rise and fall in the vertical direction. The movement of the connecting ring pushes the connecting rod to rotate, and the included angle between the connecting rod and the threaded column decreases or increases. The connecting rod pushes the plug plate to insert or disengage from the plug groove along the limiting groove, thereby realizing the fastening or unlocking of the mounting column. Moreover, the assembly component can simultaneously control multiple plug plates, further improving the convenience of worker operation.

[0016] Optionally, a touch sensor is provided on the inner sidewall of the insertion slot, and an induction lamp corresponding to each of the multiple foaming mold frames is provided on the outer surface of the turntable. The induction lamp is electrically connected to the touch sensor through a control system. When the insertion plate abuts against the touch sensor, the induction lamp lights up.

[0017] By adopting the above technical solution, when the plug-in plate comes into contact with the touch sensor, the sensor light will light up, which makes it easy for workers to know whether the foaming mold frame is installed in place from outside the turntable. This avoids the foaming mold frame shifting when the turntable rotates due to the mold frame being misaligned or not fully fixed, which could lead to problems such as injection position deviation and foaming agent leakage.

[0018] Optionally, the turntable is provided with locking grooves that correspond one-to-one with the plurality of rotating grooves. The locking grooves are perpendicular to the rotating grooves and communicate with the rotating grooves. A locking cylinder is provided inside the locking groove. The piston rod of the locking cylinder is provided with a locking rod, and the locking rod abuts against the outer end face of the threaded column.

[0019] By adopting the above technical solution, after the sensor light is turned on, the locking cylinder is activated to drive the locking rod to press against the end of the threaded column. With the help of the continuous pressure output by the locking cylinder, a uniform and stable locking force is formed, which firmly confines the threaded column in the rotating groove, thereby ensuring a stable connection between the foaming mold frame and the turntable.

[0020] Optionally, a rubber sleeve is fitted onto the end of the threaded post extending into the rotating groove, and the locking rod abuts against the outer surface of the rubber sleeve.

[0021] By adopting the above technical solution, the rubber sleeve transforms the rigid contact between the locking rod and the threaded post into a flexible contact, reducing the possibility of wear on the threaded post and the locking rod, thereby improving the service life of the threaded post and the locking rod.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application improves the production quality of sponges by setting up a drive component and an intermittent rotation component. The drive component ensures that the turntable rotates intermittently through the intermittent rotation component, providing a stable and sufficient operating time for manual operation of the injection gun to pour raw materials, reducing the probability of insufficient foaming and filling due to worker fatigue; 2. By setting up an assembly component, when the foaming mold frame is damaged or needs to be replaced with another model, the worker only needs to release the locking state of the mounting column through the assembly component, and then the foaming mold frame can be loosely removed from the turntable along the mounting groove. This eliminates the need to disassemble a large number of bolts and other connecting parts, shortens the maintenance and replacement time of the foaming mold frame, and reduces the downtime of the production line due to mold frame maintenance. 3. This application sets up a locking cylinder and a locking rod. When the locking cylinder is activated, it drives the locking rod to press against the end of the threaded column. With the help of the continuous pressure output by the locking cylinder, a uniform and stable locking force is formed, which firmly restricts the threaded column in the rotating groove, thereby ensuring a stable connection between the foaming mold frame and the turntable.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a rotary foaming machine production line.

[0030] Reference Figure 1 and Figure 2 A rotary foaming machine production line includes a workbench 1, which is installed inside the foaming workshop. A turntable 2 is rotatably connected to the workbench 1. Multiple foaming mold frames 3 are detachably installed on the surface of the turntable 2. In this embodiment, there are six foaming mold frames 3, which are evenly distributed at equal intervals along the circumference of the turntable 2. The turntable 2 and the foaming mold are both existing technologies, and their specific principles and compositions will not be described in this embodiment.

[0031] Reference Figure 1 and Figure 2 The workbench 1 has a groove 101 inside, and a drive assembly 4 and an intermittent rotation assembly 5 are arranged inside the groove 101. The drive assembly 4 includes a drive motor 41 and a reduction gearbox 42 fixedly installed inside the groove 101. The reduction gearbox 42 is existing technology in the field of transmission, and its specific principle will not be described in detail here. The output shaft of the drive motor 41 is connected to the input end of the reduction gearbox 42.

[0032] Reference Figure 1 and Figure 2 The intermittent rotation assembly 5 includes a dial 51 that is coaxially fixedly connected to the output end of the reduction gearbox 42 via a coupling. A pin 52 is fixedly connected to the outer surface of the dial 51. The pin 52 and the dial 51 are not coaxially arranged. The output shaft of the turntable 2 extends into the groove 101 and is coaxially fixedly connected to a grooved wheel 53. The grooved wheel 53 has equally divided slots 531 that correspond one-to-one with multiple foaming mold frames 3. The pin 52 is engaged with the equally divided slots 531. The rotation axis of the dial 51 has the same curvature as that of the grooved wheel 53.

[0033] Reference Figure 1 and Figure 2 The workbench 1 is provided with a movable annular groove 102, which is located on the outer periphery of the groove 101. The turntable 2 is equipped with a roller 21 that rolls with the movable annular groove 102. In this embodiment, the roller 21 is a universal wheel. Through the rolling cooperation between the movable annular groove 102 and the roller 21, a stable guide and support are provided for the rotation of the turntable 2.

[0034] During foaming, the power from the drive motor 41 is transmitted to the reduction gearbox 42. After reduction and torque amplification by the reduction gearbox 42, the power is transmitted to the dial 51. The dial 51 drives the pin 52 to revolve around its center. When the pin 52 rotates to align with one of the equal slots 531, the pin 52 embeds itself inside the slot and exerts a driving force on the slot wall. The pin 52 pushes the groove wheel 53 and the turntable 2 to rotate synchronously, thereby causing the foaming mold frame 3 to gradually approach the injection station. When the pin 52 moves to the bottom of the equal slot 531, as the dial 51 continues to rotate, the pin 52 gradually disengages from the slot 531. At this point, the groove wheel 53 loses the driving force of the pin 52. When the rotation stops, the arc surface of the dial 51 will closely fit with the outer arc surface of the grooved wheel 53 to form a positioning constraint, preventing the grooved wheel 53 from continuing to rotate under inertia. The turntable 2 will also stop. At this time, a foaming mold frame 3 will stay at the injection station, providing a stable and sufficient operating time for the worker to manually operate the injection gun to pour the raw material. After the worker finishes injection, the dial 52 will rotate into the next equal-divided groove 531 to continue driving the turntable 2 to rotate. The drive component 4 realizes the intermittent rotation of the turntable 2 through the intermittent rotation component 5, which prolongs the time for the worker to inject foam at the injection station, thereby reducing the probability of insufficient foam filling due to worker fatigue and improving the production quality of the sponge.

[0035] Reference Figure 3 and Figure 4 Each foaming film frame has multiple mounting posts 31 installed on the ground. In this embodiment, there are four mounting posts 31, which are respectively set at the four corners of the foaming film frame 3. The turntable 2 has mounting grooves 22 that slide with the multiple mounting posts 31. The turntable 2 is provided with assembly components 6 that correspond one-to-one with the six foaming film frames 3. The assembly components 6 drive the four mounting posts 31 on the corresponding foaming film frame 3 to be synchronously fastened or movably set inside the mounting grooves 22.

[0036] The assembly component 6 enables the detachable connection of the foam mold frame 3 on the turntable 2, which facilitates workers to replace damaged or different models of the foam mold frame 3 and shortens the maintenance and replacement time of the foam mold frame 3.

[0037] Reference Figure 3 and Figure 4The assembly component 6 includes a threaded post 61. A rotating groove 23 is provided on the turntable 2 to rotate with the threaded post 61. A connecting ring 62 is threadedly connected to the threaded post 61. A connecting rod 63 corresponding to each of the four mounting posts 31 is hinged to the connecting ring 62. A plug plate 64 is hinged to the end of the connecting rod 63 away from the connecting ring 62. A limiting groove 24 is provided on the turntable 2 to slide with the plug plate 64. The limiting groove 24 is parallel to the radial direction of the threaded post 61. The cross-section of the limiting groove 24 and the end of the plug plate 64 embedded in the limiting groove 24 are both inverted T-shaped to prevent the plug plate 64 from detaching from the limiting groove 24. Each mounting post 31 is provided with a plug groove 311 to plug with the plug plate 64. When the mounting post 31 abuts against the bottom surface of the mounting groove 22, the opening of the plug groove 311 is on the same straight line as the limiting groove 24.

[0038] Reference Figure 3 and Figure 4 A touch sensor (not shown in the figure) is fixedly connected to the inner wall of the plug slot 311 away from the limiting slot 24. The outer surface of the turntable 2 is equipped with a sensor lamp 7 corresponding to each of the six foaming mold frames 3. The sensor lamp 7 is electrically connected to the touch sensor through the control system. The specific electrical control principle is existing technology and is not the focus of the description in the embodiment. It will not be described in detail in this embodiment. When the plug plate 64 abuts against the touch sensor, the sensor lamp 7 lights up.

[0039] When disassembling the foaming mold frame 3, the worker rotates the threaded column 61 in the opposite direction. Under the guidance and limitation of the limiting groove 24, the rotation of the threaded column 61 drives the connecting ring 62 to move upward. The movement of the connecting ring 62 drives the connecting rod 63 to rotate. The included angle between the connecting rod 63 and the threaded column 61 decreases. The connecting rod 63 drives the plug plate 64 to exit from the plug groove 311 along the limiting groove 24. Then the worker lifts the foaming mold frame 3 upward along the mounting groove 22 to make it separate from the turntable 2. When installing the new foaming mold frame 3, the worker first aligns the mounting post 31 with the mounting slot 22 and inserts it. Then, the threaded post 61 is rotated forward. The threaded post 61 drives the connecting ring 62 to move downward. The connecting ring 62 drives the angle between the connecting rod 63 and the threaded post 61 to increase. The connecting rod 63 rotates and pushes the plug plate 64 into the plug slot 311. When the plug plate 64 abuts against the touch sensor, the sensor light 7 lights up, and the installation process of the foaming mold frame 3 is completed.

[0040] Reference Figure 3 and Figure 4To improve the stability of the foaming mold frame 3 during installation, the turntable 2 is provided with locking grooves 25 that correspond one-to-one with multiple rotating grooves 23. The locking grooves 25 are perpendicular to the rotating grooves 23 and communicate with them. A locking cylinder 8 is fixedly installed inside the locking groove 25. The piston rod of the locking cylinder 8 is coaxially fixedly connected to a locking rod 81. A rubber sleeve (not shown in the figure) is fixedly fitted on the end of the threaded post 61 extending to the rotating groove 23. The locking rod 81 abuts against the outer end face of the rubber sleeve.

[0041] After the sensor light 7 is turned on, the locking cylinder 8 is activated, which drives the locking rod 81 to press against the rubber sleeve surface of the threaded post 61. With the help of the continuous pressure output by the locking cylinder 8, a uniform and stable locking force is formed, which firmly restricts the threaded post 61 in the rotating groove 23, thereby ensuring a stable connection between the foaming mold frame 3 and the turntable 2.

[0042] The implementation principle of a rotary foaming machine production line according to an embodiment of this application is as follows: During foaming, the power of the drive motor 41 is transmitted to the reduction gearbox 42. After reduction and torque amplification by the reduction gearbox 42, the power is transmitted to the dial 51. The dial 51 drives the pin 52 to revolve around the center of the dial 51. When the pin 52 rotates to align with one of the equal-divided slots 531, the pin 52 embeds into the equal-divided slot 531 and generates a driving force on the slot wall. The pin 52 pushes the grooved wheel 53 and the turntable 2 to rotate synchronously, thereby causing the foaming mold frame 3 to gradually approach the injection station. When the pin 52 moves to the bottom of the equal-divided slot 531, as the dial 51 continues to rotate, the pin 52 gradually disengages from the equal-divided slot 531. At this time, the grooved wheel... When the drive force of the pin 52 is lost, the turntable 2 stops rotating. At the same time, the arc surface of the dial 51 will closely fit with the outer arc surface of the grooved wheel 53 to form a positioning constraint, preventing the grooved wheel 53 from continuing to rotate under inertia. The turntable 2 also stops. At this time, a foaming mold frame 3 is stationed at the injection station, providing a stable and sufficient operating time for the worker to manually operate the injection gun to pour the raw material. After the worker finishes injection, the pin 52 rotates into the next equal-divided groove 531 to continue driving the turntable 2 to rotate. The drive component 4 realizes the intermittent rotation of the turntable 2 through the intermittent rotation component 5, which prolongs the time for the worker to inject foam at the injection station, thereby reducing the probability of insufficient foam filling due to worker fatigue and improving the production quality of the sponge.

[0043] 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.
