Description

Technical Field

[0001] This application relates to the field of foaming equipment technology, and in particular to an automated production line for a direct-flow foaming machine. 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 production lines typically include a rotary table and a foaming machine. Multiple foaming mold frames are evenly arranged on the rotary table. During foaming, the rotary table rotates under the drive of the bottom geared motor, which moves the multiple foaming mold frames sequentially along a preset trajectory. When the foaming mold frame moves to the injection station of the foaming machine, the worker manually aligns the foaming gun with the foaming mold. The foaming machine starts and pours the foaming material into the mold cavity inside the foaming mold frame through the foaming gun.

[0004] However, the movement trajectory of the foaming mold frame in the rotary foaming production line is arc-shaped. The arc-shaped movement causes the foaming mold frame to be in a state of angle change as it approaches the injection station. Therefore, it is difficult to manually align the mold frame, which affects the accuracy and filling amount of the foaming raw material. This can easily lead to insufficient filling of the foaming agent in the foaming mold cavity, affecting the final molding quality of the sponge and resulting in obvious deficiencies. Utility Model Content

[0005] To improve the molding quality of sponges, this application provides an automated production line for a direct-flow foaming machine.

[0006] The automated production line for a direct-flow foaming machine provided in this application adopts the following technical solution: An automated production line for a direct-flow foaming machine includes a foaming device and a support frame. Multiple foaming mold frames are arranged along the length direction inside the support frame. A movable truss is slidably connected to the surface of the support frame along the length direction. A foaming gun is arranged on the movable truss. The foaming gun is connected to the foaming device through a material conveying pipe. An X-axis drive assembly is arranged on the movable truss, which drives the movable truss to move along the length direction of the support frame.

[0007] By adopting the above technical solution, during foaming, the X-axis drive component drives the moving truss to move along the length of the support frame. The moving truss drives the foaming gun to move along a straight trajectory. When the foaming gun moves directly above the foaming mold frame, the foaming equipment is turned on, allowing the foaming material to be injected into the mold cavity of the foaming mold frame, thus completing the filling of the foaming material. Compared with the arc-shaped movement trajectory of the traditional rotary foaming production line, the foaming gun moving along the straight trajectory is easier to align with the foaming mold frame, thereby increasing the probability of the foaming material successfully filling the mold cavity and thus improving the molding quality of the sponge.

[0008] Optionally, the X-axis drive assembly includes a drive motor disposed at the end of the movable truss, a drive gear coaxially disposed on the output shaft of the drive motor, and a drive rack plate that meshes with the drive gear is fixedly disposed on the top of the support frame along the length direction, the drive rack plate being parallel to the length direction of the support frame.

[0009] By adopting the above technical solution, the drive motor starts and drives the drive gear to rotate. Since the drive rack plate is fixedly installed on the support frame, the drive gear will roll along the drive rack plate when it rotates, thereby driving the moving truss and the foaming gun to move along the length of the support frame, so as to realize the sequential filling of multiple foaming mold frames.

[0010] Optionally, the movable truss is provided with a Y-axis drive and a Z-axis drive. The Y-axis drive is a linear electric guide rail arranged along the length of the movable truss. The moving part of the linear electric guide rail is provided with a mounting frame. A support ring for supporting the foam gun is slidably connected inside the mounting frame. The Z-axis drive is a telescopic cylinder arranged on the mounting frame. The piston rod of the telescopic cylinder is connected to the support ring.

[0011] By adopting the above technical solution, when the foaming gun needs to be adjusted in the lateral position, the linear electric guide rail drives the mounting frame to move along the length of the moving truss, thereby adjusting the foaming gun in the width direction of the support frame. This allows the foaming gun to evenly fill the foaming material inside the foaming mold frame, reducing the possibility of reduced sponge molding quality due to local accumulation. When the vertical height needs to be adjusted, the piston rod of the telescopic cylinder extends and retracts, causing the foaming gun on the support ring to slide up and down along the mounting frame. This allows the outlet of the foaming gun to be adjusted according to the depth of the foaming mold frame, avoiding the phenomenon of foaming material splashing due to excessive distance or insufficient filling due to excessive distance, thereby further improving the molding quality of the sponge.

[0012] Optionally, the support frame is provided with a linear guide rail along its length, and the bottom of the movable truss is provided with a guide block that slides with the linear guide rail.

[0013] By adopting the above technical solution, during the movement of the moving truss, the sliding cooperation of the linear guide rail and the guide block restricts the lateral deviation or vertical swaying that may occur during the movement of the moving truss, so that the moving truss always maintains a smooth movement along a straight trajectory.

[0014] Optionally, the inner wall of the linear guide rail is provided with trigger grooves corresponding to the plurality of foaming mold frames one by one. An indicator component is provided in the trigger groove. The indicator component includes a trigger ball slidably connected inside the trigger groove. A pressure sensor is fixedly provided in the inner wall of the trigger groove. A spring is provided between the pressure sensor and the trigger ball. When the spring is in its natural state, the trigger ball extends into the interior of the linear guide rail. The pressure sensor is electrically connected to an indicator light through the control system. The indicator light is located on the outer surface of the support frame. When the guide block squeezes the trigger ball into the interior of the trigger groove, the indicator light lights up. The center of the foaming gun and the center of the foaming mold frame are on the same straight line.

[0015] By adopting the above technical solution, when the guide block pushes one of the trigger balls into the trigger groove, the foam gun moves to the center line of the foam mold frame. At this time, the trigger ball is squeezed by the guide block, causing the spring to compress. The spring exerts a squeezing force on the pressure sensor. After receiving the pressure signal, the pressure sensor causes the indicator light to flash through the control system. After the worker observes the indicator light flashing, the drive motor is turned off, thereby driving the moving truss and the foam gun to stop moving, so that the foam gun stays above the foam mold frame for filling operations. The setting of the indicator component allows the worker to judge whether the foam gun and the foam mold frame are aligned simply by observing the status of the indicator light, without the need for manual visual inspection of the alignment between the foam gun and the foam mold frame, thereby further improving the accuracy of the alignment between the foam gun and the foam mold frame.

[0016] Optionally, the inner wall of the linear guide rail is provided with a limiting groove corresponding to each of the multiple trigger grooves. A limiting component is provided in the limiting groove. The limiting component includes an electromagnetic block fixedly disposed inside the limiting groove. The electromagnetic block is electrically connected to the pressure sensor through a control system. A receiving groove is provided on the guide block. A magnetic block that is attracted and cooperates with the electromagnetic block is slidably connected inside the receiving groove. A return spring is provided inside the receiving groove. The end of the return spring away from the inner wall of the receiving groove is disposed on the magnetic block. When the electromagnetic block is energized, the electromagnetic block overcomes the elastic force of the return spring and attracts the magnetic block into the limiting groove.

[0017] By adopting the above technical solution, when the pressure sensor receives a pressure signal, the pressure sensor powers the electromagnetic block through the control system. The electromagnetic block attracts the magnetic block and enters the limiting groove. At this time, one end of the magnetic block is embedded in the limiting groove, and the other end is still embedded in the receiving groove through the return spring, thereby forming a mechanical limit on the guide block. This locks the position of the moving truss and the foaming gun, reducing the possibility that the moving truss will deviate due to slight vibration of the equipment or accidental external force during the foaming material pouring process, which may cause the foaming gun to deviate from the mold cavity. After the foaming material is poured, the worker cuts off the power to the electromagnetic block through the control system. The magnetism of the electromagnetic block disappears, and the magnetic block slides back to its original position from the receiving groove under the elastic force of the return spring, releasing the limit on the guide block. Then, the drive motor is started to make the moving truss continue to move.

[0018] Optionally, multiple foaming mold frames are arranged in an array inside the support frame.

[0019] By adopting the above technical solution, after the foaming gun completes the pouring of one row of mold frames, it can quickly switch to the adjacent row of mold frame stations by moving in the Y-axis direction. There is no need to make additional adjustments to the overall layout of the moving truss or increase the number of equipment. The multi-row array of foaming mold frames increases the total amount of sponge produced per unit time and improves the overall capacity of the production line.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. This application sets up an X-axis drive component, which drives the moving truss to move the foam gun along a straight trajectory. Compared with the arc motion trajectory of the traditional rotary foam production line, the foam gun moving along the straight trajectory is easier to align with the foam mold frame, thereby increasing the probability that the foaming material can successfully fill the mold cavity and thus improving the molding quality of the sponge. 2. This application uses a Y-axis drive and a Z-axis drive. The Y-axis drive adjusts the foam gun in the width direction of the support frame, allowing the foam gun to evenly fill the foaming material inside the foaming mold frame. The Z-axis drive adjusts the height of the foam gun, allowing the outlet of the foam gun to be adjusted according to the depth of the foaming mold frame. This avoids foaming material splashing due to excessive distance or insufficient filling due to excessive distance, thereby further improving the molding quality of the sponge. 3. This application improves the accuracy of the alignment of the foam gun and the foam mold frame by setting an indicator component. The indicator component allows workers to determine whether the foam gun and the foam mold frame are aligned simply by observing the status of the indicator light, without the need for manual visual inspection of the alignment.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses an automated production line for a direct-flow foaming machine.

[0027] Reference Figure 1 and Figure 2 An automated production line for a direct-flow foaming machine includes a foaming device 01 and two support frames 1. The discharge end of the foaming device 01 is connected to a foaming gun 03 for filling the cavity of the foaming mold via a conveying pipe 02. The foaming device 01 and the two support frames 1 are installed on the floor of the foaming workshop. Multiple foaming mold frames 04 are arranged in an array inside the foaming workshop. The foaming device 01 and the foaming mold are existing technologies, and their specific principles and compositions will not be described in this embodiment. In this embodiment, the foaming mold frames 04 are arranged in two rows, with each row including five foaming mold frames 04. The two support frames 1 are respectively arranged on both sides of the two rows of foaming mold frames 04.

[0028] Reference Figure 1 and Figure 2 A movable truss 2 is mounted on the top of the two support frames 1. The movable truss 2 is parallel to the width direction of the support frame 1 and slides along the length direction of the support frame 1. The movable truss 2 is equipped with an X-axis drive assembly 3, a Y-axis drive component 4 and a Z-axis drive component 5, wherein the X-axis is parallel to the length direction of the support frame 1, the Y-axis is parallel to the width direction of the support frame 1 and the Z-axis is parallel to the height direction of the support frame 1.

[0029] Reference Figure 1 and Figure 2The X-axis drive assembly 3 includes a drive motor 31 fixedly installed at the end of the movable truss 2. The output shaft of the drive motor 31 is coaxially fixedly connected to a drive gear 32. Each support frame 1 is fixedly connected along its length to a drive rack plate 33 and a linear guide rail 6. The drive rack plate 33 meshes with the drive gear 32. The bottom surfaces at opposite ends of the movable truss 2 are fixedly connected to guide blocks 7 that slide with the linear guide rail 6. In this embodiment, the cross-sections of the linear guide rail 6 and the guide blocks 7 are inverted T-shaped.

[0030] Reference Figure 1 and Figure 2 The Y-axis drive component 4 is a linear electric guide rail arranged along the length of the movable truss 2. The branch guide rail is fixedly connected to the forward face of the movable truss 2. An installation frame 8 is fixedly installed on the moving part of the linear electric guide rail. A support ring 81 is slidably connected inside the installation frame 8. The foam gun 03 is set inside the support ring 81. The Z-axis drive component 5 is a telescopic cylinder fixedly installed on the installation frame 8. The piston rod of the telescopic cylinder is connected to the support ring 81.

[0031] During foaming, the drive motor 31 starts, driving the drive gear 32 to rotate. Since the drive rack plate 33 is fixedly installed on the support frame 1, the drive gear 32 will roll along the drive rack plate 33 when it rotates, thereby driving the moving truss 2 and the foaming gun 03 to move along a straight trajectory along the length of the support frame 1. When the foaming gun 03 moves directly above the foaming mold frame 04, the piston rod of the telescopic cylinder extends and retracts, causing the foaming gun 03 on the support ring 81 to slide up and down along the mounting frame 8, so that the discharge port of the foaming gun 03 can be adjusted according to the depth of the foaming mold frame 04. After adjustment, the foaming equipment 01 is started, and the foaming process begins. During the process of filling the foaming mold with the foam gun 03, the linear guide rail 6 drives the mounting frame 8 to move along the length of the moving truss 2, so that the foam gun 03 can evenly fill the foaming material into the foaming mold frame 04. The foaming equipment 01 is turned on so that the foaming material is injected into the mold cavity of the foaming mold frame 04. In this way, the filling work of one foaming mold frame 04 is completed. Compared with the arc-shaped movement trajectory of the traditional rotary foaming production line, the foam gun 03, which moves along the linear trajectory, is easier to align with the foaming mold frame 04, thereby increasing the probability of the foaming material successfully filling the mold cavity and thus improving the molding quality of the sponge.

[0032] Reference Figure 1 and Figure 3The inner wall of the linear guide rail 6 is provided with trigger slots 61 corresponding to the five foaming mold frames 04. An indicator component 9 is provided in the trigger slot 61. The indicator component 9 includes a trigger ball 91 slidably connected inside the trigger slot 61. The arc surface of the trigger ball 91 faces the inside of the linear guide rail 6. A pressure sensor 92 is fixedly installed on the inner wall of the trigger slot 61 away from the linear guide rail 6. The pressure sensor 92 and the trigger ball 91 are connected by a spring 93. When the spring 93 is in its natural state, the arc surface of the trigger ball 91 extends into the inside of the linear guide rail 6. The pressure sensor 92 is electrically connected to an indicator light 10 through the control system. The specific electrical control principle is existing technology and is not the focus of the description in this embodiment. It will not be described in detail in this embodiment. The indicator light 10 is installed on the outer surface of the support frame 1. When the pressure sensor 92 receives a pressure signal, the indicator light 10 lights up. At this time, the center of the foaming gun 03 and the foaming mold frame 04 are on the same straight line.

[0033] When the moving truss 2 drives the guide block 7 to push one of the trigger balls 91 into the trigger groove 61, the foam gun 03 moves to the center line of the foam mold frame 04. At this time, the trigger ball 91 is squeezed by the guide block 7, which compresses the spring 93. The spring 93 exerts a squeezing force on the pressure sensor 92. After receiving the pressure signal, the pressure sensor 92 causes the indicator light 10 to flash through the control system. After the worker observes the indicator light 10 flashing, the drive motor 31 is turned off, which in turn drives the moving truss 2 and the foam gun 03 to stop moving, so that the foam gun 03 stays above the foam mold frame 04 to perform the filling operation. The setting of the indicator component 9 allows the worker to judge whether the foam gun 03 and the foam mold frame 04 are aligned by simply looking at the status of the indicator light 10. There is no need for manual observation of the alignment degree of the foam gun 03 and the foam mold frame 04, thereby further improving the accuracy of the alignment between the foam gun 03 and the foam mold frame 04.

[0034] Reference Figure 1 and Figure 3 The inner wall of the linear guide 6 is provided with limiting grooves 62 corresponding to multiple trigger grooves 61. The trigger grooves 61 and the corresponding limiting grooves 62 are respectively set on the inner walls of the linear guide 6. Each limiting groove 62 is provided with a limiting component 11. The limiting component 11 includes an electromagnetic block 111 fixedly connected to the inner wall of the limiting groove 62. The electromagnetic block 111 is electrically connected to the pressure sensor 92 through the control system. The guide block 7 is provided with a receiving groove 71. A magnetic block 112 that is attracted and cooperates with the electromagnetic block 111 is slidably connected inside the receiving groove 71. A return spring 113 is provided inside the receiving groove 71. The end of the return spring 113 away from the inner wall of the receiving groove 71 is fixedly connected to the magnetic block 112. When the electromagnetic block 111 is energized, the attraction force of the electromagnetic block 111 on the magnetic block 112 is greater than the elastic force of the return spring 113.

[0035] When the pressure sensor 92 receives the pressure signal, it powers the electromagnetic block 111 through the control system. The electromagnetic block 111 attracts the magnetic block 112 and enters the limiting groove 62. At this time, one end of the magnetic block 112 is embedded in the limiting groove 62, and the other end is still embedded in the receiving groove 71 through the return spring 113, thus forming a mechanical limit on the guide block 7. This locks the positions of the moving truss 2 and the foaming gun 03, reducing the possibility that the moving truss 2 may deviate due to slight vibration of the equipment or accidental external force during the foaming material pouring process, which could cause the foaming gun 03 to deviate from the mold cavity. After the foaming material is poured, the worker cuts off the power to the electromagnetic block 111 through the control system. The magnetism of the electromagnetic block 111 disappears, and the magnetic block 112 slides back to its original position from the receiving groove 71 under the elastic force of the return spring 113, releasing the limit on the guide block 7. Then, the drive motor 31 is started to move the moving truss 2 to the next foaming mold for foaming.

[0036] The implementation principle of an automated production line for a direct-discharge foaming machine according to an embodiment of this application is as follows: During foaming, the drive motor 31 starts and drives the drive gear 32 to rotate. Since the drive rack plate 33 is fixedly installed on the support frame 1, the drive gear 32 will roll along the drive rack plate 33 when it rotates, thereby driving the moving truss 2 and the foaming gun 03 to move along a straight trajectory along the length of the support frame 1. When the foaming gun 03 moves directly above the foaming mold frame 04, the piston rod of the telescopic cylinder extends and retracts, causing the foaming gun 03 on the support ring 81 to slide up and down along the mounting frame 8, so that the discharge port of the foaming gun 03 can be adjusted according to the depth of the foaming mold frame 04. After adjustment... After completion, the foaming equipment 01 is started. During the process of the foaming gun 03 filling the foaming mold, the linear guide rail 6 drives the mounting frame 8 to move along the length of the moving truss 2, so that the foaming gun 03 can evenly fill the foaming material into the foaming mold frame 04. The foaming equipment 01 is turned on so that the foaming material is injected into the mold cavity of the foaming mold frame 04. In this way, the filling work of one foaming mold frame 04 is completed. Compared with the arc motion trajectory of the traditional rotary foaming production line, the foaming gun 03, which moves along the linear trajectory, is easier to align with the foaming mold frame 04, thereby increasing the probability of the foaming material successfully filling the mold cavity and thus improving the molding quality of the sponge.

[0037] 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.
