Description

Technical Field

[0001] This invention relates to the field of foam production equipment technology, specifically a winding device for foam production. Background Technology

[0002] In the foam production process, winding is a crucial step. Existing foam winding devices often leave the foam roll tightly wound around the winding roller after winding, making it difficult for operators to remove. This process frequently requires significant time and effort, severely impacting production efficiency. Furthermore, removing the foam roll can easily damage the foam, affecting product quality.

[0003] To address the aforementioned issues, those skilled in the art have made numerous attempts. For instance, the invention patent with authorization announcement number CN118458451B discloses a foam roll production device. This device includes a base plate and a mounting plate. A first rotating shaft is rotatably mounted on the side of the mounting plate near the base plate. A winding mechanism is provided on the first rotating shaft, which includes an arc-shaped clamping plate and a third fixing plate. Multiple second electric telescopic rods are evenly installed along the circumferential direction on the outer side of the first rotating shaft. The arc-shaped clamping plate is installed at the telescopic end of the second electric telescopic rod. The extension and retraction of the arc-shaped clamping plate are achieved by the extension and retraction of the second electric telescopic rod, thereby facilitating the unloading of the foam roll. At the same time, the device also includes a first auxiliary mechanism and a second auxiliary mechanism, which can realize functions such as foam material detection, cutting, and wrapping with a coating film, thereby improving the automation level of foam production to a certain extent.

[0004] However, the winding device in the aforementioned patent still has some shortcomings in actual use. The arc-shaped clamp of its winding mechanism is driven to extend and retract by a second electric telescopic rod, which is relatively complex and costly. Furthermore, the stability of the electric telescopic rod may be affected by long-term, high-frequency use. In addition, the unloading process of this device requires the coordinated action of multiple components, making the operation process cumbersome. There is still room for improvement in the rapid removal of foam rolls.

[0005] Some have a retractable structure on the take-up roller, which extends during winding to ensure winding stability and retracts when the foam roll is removed for easy removal. However, these structures are often complicated to operate, have low reliability, and are difficult to meet the needs of actual production.

[0006] In view of this, the present invention provides a winding device for foam production to solve the problems of difficulty in removing foam rolls, which affects production efficiency and product quality in the prior art. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art.

[0008] This application provides a winding device for foam production, including a winding roller, a frame, and a drive unit. It also includes a conveyor belt, a turning device, an expansion device, and a reset device. The conveyor belt is disposed at the bottom of the inner cavity of the frame. The expansion device is disposed in the winding roller and has a plurality of beams floatingly mounted on the surface of the winding roller. The turning device is used to make the winding roller horizontal or vertical with the conveyor belt. When the winding roller is horizontal / vertical, the outer ends of the beams of the expansion device extend to be higher than the surface of the winding roller / retract to be flush with the surface of the winding roller under the action of the reset device.

[0009] The flipping device includes a guide groove, a pair of transmission rods, a mounting beam, a gear plate, a gear, and a sliding frame.

The lower end of the guide groove is perpendicular to the conveyor belt, and the upper end is parallel to the conveyor belt. The sliding frame is U-shaped and fixed to the peripheral wall of the gear plate. The inner cavity is slidably engaged with one of the transmission rods. The take-up roller is rotatably mounted on the mounting beam.

[0010] The bulging device includes a vertical plate, a sliding cavity, a bulging groove, a floating tube, a connecting rod, and a locking assembly. The vertical plate is fixed to one end of the frame and has a through groove at the top. The reset device is located at the other end of the frame. The sliding cavity is located in the inner cavity of the take-up roller and is open towards the vertical plate. The floating tube is slidably inserted into the sliding cavity. The beam is floatingly installed in the bulging groove and is connected to the floating tube via the connecting rod. A spring is provided between the inner end of the floating tube and the inner end of the sliding cavity.

[0011] The drive unit includes a driven disc fixed at the end of the take-up roller, drive slots spaced circumferentially around the driven disc, and a drive disc mounted on the inner side of the upright plate by a motor. The surface of the drive disc is fixed with a number of drive columns for cooperating with the drive slots.

[0012] The engagement assembly includes a reset post, an engagement component, a reset component, and a toothed post. The reset component is located at the outer end of the floating tube and slides in engagement with the toothed post. The toothed post is fixed at the outer end of the reset post. The reset post slides through the floating tube. The engagement component is floatingly mounted on the reset post. The inner wall of the floating tube is provided with a slot for engaging with the engagement component. The reset device is used to engage with the toothed post when the take-up roller is perpendicular to the conveyor belt, so that the reset post and the engagement component rotate and the engagement component disengages from the slot.

[0013] The locking component includes a floating groove formed on the surface of the reset post, a pair of inserts floatingly mounted in the floating groove, and a spring two disposed between the inner ends of the pair of inserts. An inclined surface is provided on one side of the locking groove.

[0014] The reset component includes a reset plate fixed to the outer end of the floating tube, an arc groove is opened on the reset plate, a reset block is rotatably installed in the arc groove, a spring is provided between one side of the reset block and one end of the arc groove, and a toothed groove is opened on the inner end to mesh with the toothed column.

[0015] The reset component also includes an annular groove, which is formed on the outer surface of the reset disk and the reset block, and a retaining ring is installed in the annular groove.

[0016] The reset device includes a horizontal plate fixed in the inner cavity of the frame away from the end of the clamping plate, a notch opened on the horizontal plate, a rack set on one side of the notch, and a pressure plate slidably installed at the bottom of the horizontal plate. The end of the pressure plate facing the vertical plate is provided with a limiting groove that matches the shape of the driven plate. A baffle is fixed at the bottom of the horizontal plate, and a spring is provided between the end of the pressure plate away from the limiting groove and the baffle.

[0017] The reset device also includes L-grooves symmetrically arranged on the inner side wall of the frame and sliders fixed on the side wall of the pressure plate. The sliders are slidably installed in the L-grooves. The vertical section of the L-grooves is connected to the top of the inner side wall of the frame, and the horizontal section extends to the bottom of the horizontal plate. A through hole is opened on the side wall of the frame, which is connected to the middle of the horizontal section, and a fixing pin is inserted in the through hole.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention, by setting up a flipping device, enables the winding roller to switch between two states: horizontal and perpendicular to the conveyor belt. When the winding roller is horizontal, the outer end of the beam of the expansion device extends above the surface of the winding roller, which facilitates the fixing of the starting end of the foam onto the winding roller and ensures smooth winding. After winding is completed, the winding roller is perpendicular to the conveyor belt, and the beam retracts to be flush with the surface of the winding roller under the action of the reset device, which facilitates the automatic feeding of the foam roll from the winding roller onto the conveyor belt, improving the convenience of operation and production efficiency.

[0020] 2. The ingenious structural design of the flipping device, through the cooperation of the guide groove, transmission rod, mounting beam, gear plate, gear and sliding frame, can stably realize the flipping action of the take-up roller. The shape design of the guide groove makes the movement trajectory of the transmission rod reasonable, ensuring the accurate position of the take-up roller in horizontal and vertical states, and improving the stability and reliability of the device.

[0021] 3. The bulging device, through the cooperation of structures such as the vertical plate, sliding cavity, bulging groove, floating tube, connecting rod and locking assembly, can realize the extension and retraction of the beam. The setting of spring one provides the restoring force for the floating tube, ensuring that the beam can retract smoothly when the foam roll needs to be removed.

[0022] 4. The drive unit adopts a combination of driven disc, drive groove, drive disc and drive column, which can stably drive the winding roller to rotate, and can be easily separated or connected with the flipping device to ensure the continuity and stability of the winding operation. The precise matching between the drive column and drive groove avoids slippage and other problems.

[0023] 5. The locking assembly enables the floating tube to be locked and unlocked, ensuring the stable extension of the beam strip during the winding process. The cooperation between the reset device and the toothed column enables the locking component to be unlocked when the winding roller is perpendicular to the conveyor belt, allowing the beam strip to retract smoothly under the action of the spring reset force, which facilitates the removal of the foam roll.

[0024] 6. The reset component has a reasonable structural design. Spring 3 provides the reset force for the reset block. The meshing of the tooth groove and the tooth column ensures the accuracy of the rotation of the reset column. The setting of the ring groove and the retaining ring improves the stability of the reset component.

[0025] 7. The structure of the reset device enables the rotation of the reset column through the cooperation of the rack and pinion, ensuring the smooth unlocking of the locking parts. The L-groove, slider, through hole and fixing pin can limit the pressure plate, improving the reliability of the reset device. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] The following description, in conjunction with the accompanying drawings, details the winding device for foam production provided in this application through specific embodiments and application scenarios.

[0037] Example 1:

[0038] This application provides a winding device for foam production, including a winding roller 1, a frame 2, and a drive device 3. It also includes a conveyor belt 4, a flipping device 5, an expansion device 6, and a reset device 7. The conveyor belt 4 is disposed at the bottom of the inner cavity of the frame 2. The expansion device 6 is disposed in the winding roller 1 and has a plurality of beams floating on the surface of the winding roller 1. The flipping device 5 is used to make the winding roller 1 horizontal or vertical with the conveyor belt 4. When the winding roller 1 is horizontal / vertical, the outer ends of the beams of the expansion device 6 extend to be higher than the surface of the winding roller 1 / retract to be flush with the surface of the winding roller 1 under the action of the reset device 7.

[0039] In this embodiment of the application, the flipping device 5 includes a guide groove 51, a pair of transmission rods 52, a mounting beam 53, a gear 54, a gear 55, and a sliding frame 56. The guide groove 51 is symmetrically arranged on the inner wall of the frame 2. The gear 54 and the gear 55 are rotatably mounted on the inner wall of the frame 2. The gear 55 is driven by a motor. The pair of transmission rods 52 are fixed to the mounting beam 53. The ends of the transmission rods 52 are slidably mounted in the guide groove 51. The lower end of the guide groove 51 is perpendicular to the conveyor belt 4, and the upper end is parallel to the conveyor belt 4. The sliding frame 56 is U-shaped and fixed to the peripheral wall of the gear 54. The inner cavity is slidably engaged with one of the transmission rods 52. The take-up roller 1 is rotatably mounted on the mounting beam 53.

[0040] like Figures 1 to 6 As shown, due to the aforementioned structure, when the take-up roller 1 is parallel to the conveyor belt 4, the beam of the bulging device 6 bulges out. After completing the take-up of the foam, the motor drives the gear 55 to rotate, which in turn drives the gear disc 54 to rotate. The gear disc 54 then drives the U-shaped sliding frame 56 to rotate. The sliding frame 56 is in sliding engagement with one of the transmission rods 52, thereby pushing the transmission rod 52 to slide within the guide groove 51. The transmission rod 52 drives the mounting beam 53 to move. Because the lower end of the guide groove 51 is perpendicular to the conveyor belt 4 and the upper end is parallel to the conveyor belt 4, the mounting beam 53 drives the take-up roller 1 from... The state perpendicular to the conveyor belt 4 is gradually flipped to a horizontal state. The reset device 7 is activated to retract the beams of the expansion device 6. Under the action of gravity, the foam roll falls from the take-up roller 1 onto the conveyor belt 4. The conveyor belt sends the foam roll out of the frame 2. Then, the motor drives the gear 55 to rotate in the opposite direction. The gear plate 54 and the sliding frame 56 move in the opposite direction. The transmission rod 52 slides in the opposite direction in the guide groove 51. The mounting beam 53 drives the take-up roller 1 to flip from the horizontal state back to the state perpendicular to the conveyor belt 4. The beams of the expansion device 6 extend, realizing the state switching of the take-up roller 1.

[0041] Example 2:

[0042] The difference from Embodiment 1 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the bulging device 6 includes a vertical plate 61, a sliding cavity 62, a bulging groove 63, a floating tube 64, a connecting rod 65, and a locking assembly 8. The vertical plate 61 is fixed to one end of the frame 2 and has a through groove at the top. The reset device 7 is located at the other end of the frame 2. The sliding cavity 62 is located in the inner cavity of the take-up roller 1 and is open towards the vertical plate 61. The floating tube 64 is slidably inserted into the sliding cavity 62. The beam is floatingly installed in the bulging groove 63 and is connected to the floating tube 64 by the connecting rod 65. A spring 66 is provided between the inner end of the floating tube 64 and the inner end of the sliding cavity 62.

[0043] In this embodiment of the application, the drive device 3 includes a driven disk 31 fixed at the end of the take-up roller 1, drive grooves 32 spaced around the driven disk 31 in the circumferential direction, and a drive disk 33 mounted on the inner side of the upright plate 61 by a motor. The surface of the drive disk 33 is provided with a plurality of drive disks 34 for cooperating with the drive grooves 32.

[0044] like Figures 1 to 2 As shown, due to the above structure, when the take-up roller 1 is in a horizontal state, under the action of the vertical plate 61, the floating tube 64 slides into the sliding cavity 62, and pushes the beam bar to extend out of the bulging groove 63 through the connecting rod 65, which is higher than the surface of the take-up roller 1. At the same time, the motor drives the drive disk 33 to rotate, and the drive disk 34 on the drive disk 33 is embedded in the drive groove 32 of the driven disk 31, driving the driven disk 31 and the take-up roller 1 to rotate, so as to perform foam winding.

[0045] When the take-up roller 1 is in a vertical state, under the action of the reset device 7 and the spring 66, the floating tube 64 slides out of the sliding cavity 62 and compresses the spring 66. The connecting rod 65 pulls the beam back into the bulging groove 63, which is flush with the surface of the take-up roller 1. The drive disc 34 disengages from the drive groove 32, and the take-up roller 1 stops winding.

[0046] Example 3:

[0047] The difference from Embodiment 2 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the engaging assembly 8 includes a reset post 81, an engaging member 82, a reset member 83, and a toothed post 84. The reset member 83 is disposed at the outer end of the floating tube 64 and slides in cooperation with the toothed post 84. The toothed post 84 is fixed at the outer end of the reset post 81. The reset post 81 slides through the floating tube 64. The engaging member 82 is floatingly mounted on the reset post 81. The inner wall of the floating tube 64 is provided with a slot 85 for engaging with the engaging member 82. The reset device 7 is used to cooperate with the toothed post 84 when the take-up roller 1 is perpendicular to the conveyor belt 4, so that the reset post 81 and the engaging member 82 rotate and the engaging member 82 disengages from the slot 85.

[0048] In this embodiment of the application, the locking member 82 includes a floating groove 821 formed on the surface of the reset post 81, a pair of inserts 822 floatingly mounted in the floating groove 821, and a spring 823 disposed between the inner ends of the pair of inserts 822. A slope is provided on one side of the locking groove 85.

[0049] like Figure 2 and Figure 6 As shown, due to the above structure, during forward operation, as the beam extends, the floating tube 64 slides into the sliding cavity 62 until each slot 85 aligns with the corresponding insert 822. The pair of inserts 822 on the reset column 81 pops out under the action of the second spring 823 and engages with the slots 85 on the inner wall of the floating tube 64, locking the floating tube 64 and keeping the beam extended.

[0050] When the take-up roller 1 is perpendicular to the conveyor belt 4, the reset device 7, in conjunction with the toothed column 84, causes the reset column 81 to rotate. The insert block 822, under the action of the inclined surface of the slot 85, compresses the second spring 823 and retracts into the floating groove 821, disengaging from the slot 85. The floating tube 64, under the reverse force of the first spring 66 or the action of the reset device 7, slides out of the sliding cavity 62, causing the beam bar to retract.

[0051] Example 4:

[0052] The difference from Embodiment 3 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the reset member 83 includes a reset disk 831 fixed to the outer end of the floating tube 64, an arc groove 832 is formed on the reset disk 831, a reset block 833 is rotatably installed in the arc groove 832, a spring 834 is provided between one side of the reset block 833 and one end of the arc groove 832, and a toothed groove is formed on the inner end to mesh with the toothed post 84.

[0053] In this embodiment of the application, the reset member 83 further includes an annular groove 835, which is formed on the outer surface of the reset disk 831 and the reset block 833, and a retaining ring 836 is installed in the annular groove 835.

[0054] like Figures 2 to 4As shown, due to the above structure, when the take-up roller 1 is perpendicular to the conveyor belt 4, the mounting beam 53 is parallel to the conveyor belt 4, and the motor cooperating with the gear 55 continues to run, causing the mounting beam 53 to move towards the reset device 7. The reset device 7 circumferentially fixes the take-up roller 1 and drives the toothed column 84 to rotate, causing the reset column 81 to rotate relative to the take-up roller 1 and the floating tube 64. The insert block 822 compresses the second spring 823 under the action of the inclined surface of the slot 85, retracts into the floating groove 821, and disengages from the slot 85. The reset block 833 slides towards the other end of the arc groove 832. The third spring 834 is compressed and stores elastic potential energy, while the first spring 66 releases elastic potential energy to push... The floating tube 64 slides out of the sliding cavity 62, the beams descend, and the slots 85 and corresponding inserts 822 are misaligned. After the foam roll is unloaded, the motor cooperating with the gear 55 reverses, causing the mounting beam 53 to move away from the reset device 7 and become perpendicular to the conveyor belt 4. The reset piece 83 separates from the reset device 7, and the springs 834 release their elastic potential energy to reset the reset block 833, driving the toothed column 84 and the reset rod to reverse and reset, so that the inserts 822 and the slots 85 are on the same straight line. When the floating sleeve extends into the inner end of the sliding cavity 62, the inserts 822 can be inserted into the slots 85 under the action of the springs 823 to complete the fixation of the sliding cavity 62.

[0055] Example 5:

[0056] The difference from Embodiment 4 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the reset device 7 includes a horizontal plate 71 fixed in the inner cavity of the frame 2 away from the end of the card plate, a notch 72 opened on the horizontal plate 71, a rack 73 provided on one side of the notch 72, and a pressing plate 74 slidably installed at the bottom of the horizontal plate 71. The end of the pressing plate 74 facing the vertical plate 61 is provided with a limiting groove 75 that is adapted to the shape of the driven plate 31. A baffle 76 is fixed at the bottom of the horizontal plate 71, and a spring 77 is provided between the end of the pressing plate away from the limiting groove 75 and the baffle 76.

[0057] In this embodiment of the application, the reset device 7 further includes an L-groove 78 symmetrically arranged on the inner sidewall of the frame 2 and a slider 79 fixed on the sidewall of the pressure plate 74. The slider 79 is slidably installed in the L-groove 78. The vertical section of the L-groove 78 communicates with the top of the inner sidewall of the frame 2, and the horizontal section extends to the bottom of the horizontal plate 71. A through hole 710 communicating with the middle of the horizontal section is opened on the sidewall of the frame 2, and a fixing pin 711 is inserted into the through hole 710.

[0058] like Figures 2 to 5As shown, due to the above structure, during the movement of the mounting beam 53, the take-up roller 1 moves closer to the reset device 7 along with it. When the take-up roller 1 approaches the reset device 7, the pressing plate 74 of the reset device 7, under the action of the spring 77, slides the slider 79 along the horizontal section of the L groove 78, and the driven plate 31 enters the limiting groove 75 to achieve circumferential fixation of the take-up roller 1. At the same time, the rack 73 on the side of the notched groove 72 on the horizontal plate 71 meshes with the toothed column 84.

[0059] As the mounting beam 53 continues to move toward the reset device 7, the take-up roller 1 is in a circumferentially fixed state, and the toothed column 84 moves along the rack 73. The rack 73 drives the toothed column 84 to rotate, which in turn causes the reset column 81 to rotate relative to the take-up roller 1 and the floating tube 64. At this time, the insert block 822 on the reset column 81 is squeezed by the inclined surface of the slot 85. The insert block 822 compresses the spring 823 and gradually retracts into the floating groove 821, eventually disengaging from the slot 85 and releasing the lock between the floating tube 64 and the take-up roller 1.

[0060] During the rotation of the reset pin 81, the toothed pin 84 drives the reset block 833, which meshes with it, to rotate. The reset block 833 slides along the arc groove 832 to the other end. The spring 834 is compressed, its length is shortened and it stores elastic potential energy. The retaining ring 836 moves synchronously with the reset block 833 in the ring groove 835 to ensure the stability of the reset block 833 during rotation.

[0061] Through the coordinated operation of the above components, the positional movement and circumferential fixation of the take-up roller 1 in a state perpendicular to the conveyor belt 4, as well as the preparation work for the retraction of the beam strip, are realized, which facilitates the subsequent removal of the foam roll.
