Abstract
Description
Technical Field
[0001] This application relates to the field of headrest foam processing technology, and in particular to a foam breaking machine for headrest foam production. Background Technology
[0002] Currently, expanded polystyrene foam is commonly used as filling material in car seats, headrests, and armrests to improve user safety and comfort. During the processing of expanded polystyrene foam into headrests after production, a foam-breaking machine is typically used to break down the foam bubbles, creating a smooth surface.
[0003] A bubble-breaking machine has been proposed in related technologies, including an operating table, side limiting plates opposite to each other on the operating table, a connecting limiting plate connecting the two side limiting plates, an extrusion plate and rollers slidably connected to the operating table, and the above four plates forming a rectangle. In use, the workpiece is placed within the rectangular space enclosed by the four plates, and the rollers are driven to roll over the surface of the workpiece to break bubbles. The four plates act as limiting plates, preventing severe deformation of the workpiece around its edges during the rolling process, thus reducing the damage rate.
[0004] Regarding the aforementioned technologies, since the side limit plates and connecting limit plates are fixedly connected to the operating table, the fixed limit plates are not applicable when it is necessary to perform bubble breaking operations on workpieces of different sizes, thus reducing the applicability of the bubble breaking machine. Utility Model Content
[0005] To address the issue that fixed limiting plates are not suitable for defoaming workpieces of different sizes, thus reducing the applicability of the defoaming machine, this application provides a defoaming machine for headrest foam production.
[0006] The present application provides a foam breaking machine for producing headrest foam, which adopts the following technical solution:
[0007] A foam breaking machine for producing headrestling foam includes a base, a fixed plate, a first sliding plate, a second sliding plate, a third sliding plate, and a foam breaking mechanism. The fixed plate is fixedly connected to the left side of the upper surface of the base. The first sliding plate is slidably connected to the right side of the upper surface of the base along a transverse direction. The base is provided with a first driving mechanism for driving the first sliding plate to move. The second sliding plate is slidably connected to the upper side of the upper surface of the base along a longitudinal direction. The third sliding plate is slidably connected to the lower side of the upper surface of the base along a longitudinal direction. The fixed plate is provided with a second driving mechanism for synchronously driving the second and third sliding plates to move closer or further apart. The foam breaking mechanism is located at the top of the base and is used to break bubbles on the upper surface of the workpiece.
[0008] By adopting the above technical solution, when the bubble-breaking mechanism performs bubble-breaking treatment on the upper surface of the workpiece, the first driving mechanism drives the first sliding plate to move laterally, and the second driving mechanism simultaneously drives the second sliding plate and the third sliding plate to move closer or further away longitudinally, which can form a stable clamping and fixing of the workpiece, adapt to the limiting of workpieces of different sizes, and improve the problem that when it is necessary to perform bubble-breaking operations on workpieces of different sizes, the fixed limiting plate is not applicable, which reduces the applicability of the bubble-breaking machine.
[0009] Optionally, the first driving mechanism includes a lead screw and a handwheel. A groove is provided on the base along the moving direction of the first sliding plate. The lead screw is provided on the base along the extending direction of the groove and is rotatably connected to the base around its own length. The lead screw passes through the first sliding plate and is threadedly connected to the first sliding plate. The handwheel is located at the end of the lead screw.
[0010] By adopting the above technical solution, the threaded connection between the lead screw and the first sliding plate, combined with the handwheel setting, enables precise control of the first sliding plate, making the lateral movement of the first sliding plate on the base more stable and accurate. The handwheel is simple and convenient to operate, requiring no additional power source, reducing the complexity and cost of the equipment, and improving the ease of operation of the foam breaking machine for headrest foam production.
[0011] Optionally, the second driving mechanism includes a gear, a first rack, and a second rack. The gear is rotatably connected to a fixed plate about a vertical axis. The first rack is connected to a second sliding plate, and the second rack is connected to a third sliding plate. The gear meshes with the first rack and the second rack.
[0012] By adopting the above technical solution, the meshing structure of the gear with the first and second racks can achieve the effect of synchronously driving the second and third sliding plates to move closer or further apart. This design simplifies operation; simply rotating the gears is enough to simultaneously control the movement direction and distance of the two sliding plates, improving the operating efficiency and stability of the equipment.
[0013] Optionally, a toothed block is slidably connected to the fixed plate, and a return spring is connected to the toothed block. The other end of the return spring is connected to the fixed plate, and the return spring tends to bring the toothed block closer to the gear and mesh with the gear.
[0014] By adopting the above technical solution, the tooth block can closely fit and mesh with the gear under the action of the return spring, thereby effectively preventing the gear from rotating unexpectedly in the non-operating state and improving the stability of equipment operation.
[0015] Optionally, buffer pads are provided on the side walls of the fixed plate, the first sliding plate, the second sliding plate and the third sliding plate.
[0016] By adopting the above technical solution, the buffer pad can effectively reduce the impact force generated when each sliding plate collides with the workpiece or other components during movement, thereby protecting the workpiece surface from scratches or damage, while reducing the wear of the equipment itself caused by collisions and extending the service life of the equipment.
[0017] Optionally, the bubble-breaking mechanism includes a bracket, a sliding seat, a mounting seat, a roller cylinder, and a linear drive component. The sliding seat is slidably connected to the bracket along the longitudinal direction, and the linear drive component is disposed on the bracket for driving the sliding seat to move. The mounting seat is disposed on the sliding seat, and the roller cylinder is rotatably connected to the bottom of the mounting seat. The sliding seat is provided with an adjustment component for adjusting the height of the mounting seat.
[0018] By adopting the above technical solution, the linear drive component drives the sliding seat to move, adjusting the position of the roller cylinder above the workpiece, so that the roller cylinder can uniformly perform bubble-breaking treatment on the workpiece surface, ensuring the accuracy of the bubble-breaking operation; the setting of the adjustment component can adjust the height of the mounting seat according to the workpiece thickness or bubble-breaking requirements, thereby adjusting the distance between the roller cylinder and the workpiece surface, adapting to different working conditions, and improving the versatility and bubble-breaking effect of the equipment.
[0019] Optionally, the adjustment assembly includes a guide rod and a threaded rod. The guide rod is vertically connected to the mounting base, and the threaded rod is rotatably connected to the mounting base about the vertical direction. Both the guide rod and the threaded rod pass through the sliding seat vertically, and the threaded rod is threadedly connected to the sliding seat.
[0020] By adopting the above technical solution, the guide rod is positioned to provide stable guidance to the mounting base, preventing it from shifting during height adjustment and ensuring uniform pressure from the roller cylinder on the workpiece. The threaded connection design between the threaded rod and the sliding seat allows for fine-tuning of the mounting base by rotating the threaded rod, making operation simple and positioning precise, further improving the working stability and bubble-breaking effect of the bubble-breaking machine.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The adjustable design of the first sliding plate, the second sliding plate and the third sliding plate can adapt to foam workpieces of different sizes and shapes, improving the versatility and flexibility of the equipment;
[0023] 2. The second drive mechanism, which combines gears and racks, allows for simultaneous control of the movement direction and distance of the two sliding plates simply by rotating the gears, making operation simpler and improving the operating efficiency and stability of the equipment;
[0024] 3. The combination of the gear block and the return spring effectively prevents the gear from rotating unexpectedly when not in operation, thus improving the stability of the equipment operation. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a foam breaking machine for producing headrest foam. (See also...) Figure 1 The foam breaking machine for headrestling foam production includes a base 1, a fixed plate 2, a first sliding plate 3, a second sliding plate 4, a third sliding plate 5, and a foam breaking mechanism 6. The fixed plate 2 is fixedly connected to the left side of the upper surface of the base 1. The first sliding plate 3 is slidably connected laterally to the right side of the upper surface of the base 1. A first drive mechanism for moving the first sliding plate 3 is mounted on the base 1. The second sliding plate 4 is slidably connected longitudinally to the upper surface of the base 1, and the third sliding plate 5 is slidably connected longitudinally to the lower surface of the upper surface of the base 1. A second drive mechanism for synchronously driving the second sliding plate 4 and the third sliding plate 5 to move closer or further apart is mounted on the fixed plate 2. The foam breaking mechanism 6 is located at the top of the base 1 and is used to break bubbles on the upper surface of the workpiece.
[0032] In use, the workpiece is placed directly on the upper surface of the base 1 with one side resting against the fixed plate 2. Then, the first driving mechanism drives the first sliding plate 3 to slide laterally and contact the workpiece. Next, the second driving mechanism simultaneously drives the second sliding plate 4 and the third sliding plate 5 to move closer together and contact the workpiece. This completes the positioning and restraint of the workpiece. Then, the bubble-breaking mechanism 6 performs bubble-breaking treatment on the upper surface of the workpiece. The sliding connection of the first sliding plate 3, the second sliding plate 4, and the third sliding plate 5, combined with the first and second driving mechanisms, can limit the movement of workpieces of different lengths and widths. This improves upon the problem that fixed limiting plates are not suitable when bubble-breaking operations are required for workpieces of different sizes, thus improving the applicability of the bubble-breaking machine.
[0033] In addition, to reduce damage to the workpiece during clamping and limiting, buffer pads 7 are provided on the side walls of the fixed plate 2, the first sliding plate 3, the second sliding plate 4, and the third sliding plate 5. The buffer pads 7 can be made of flexible materials, such as rubber or silicone, and their thickness can be adjusted according to actual needs. For example, when handling softer foam workpieces, a thicker buffer pad 7 can be selected to provide better protection. The buffer pads 7 are installed using adhesive bonding for easy replacement and maintenance.
[0034] The first driving mechanism includes a lead screw 11 and a handwheel 12. A groove 13 is formed on the base 1 along the sliding direction of the first sliding plate 3. The lead screw 11 extends along the groove 13 on the base 1 and is rotatably connected to the base 1 about its own length. The lead screw 11 passes through the first sliding plate 3 and is threadedly connected to it. The handwheel 12 is located at the end of the lead screw 11. Rotating the handwheel 12 drives the lead screw 11 to rotate, thereby driving the first sliding plate 3 to move laterally along the groove 13. The lead screw 11 can be made of stainless steel, which has high strength and wear resistance, while the handwheel 12 can be made of plastic to reduce weight and facilitate operation. The threaded connection between the lead screw 11 and the first sliding plate 3 ensures the accuracy and stability of the movement of the first sliding plate 3.
[0035] For example, refer to Figure 2The second drive mechanism includes a gear 21, a first rack 22, and a second rack 23. A mounting slot 24 is provided on the fixed plate 2 along the sliding direction of the second sliding plate 4 and the third sliding plate 5. The gear 21 is rotatably connected to the mounting slot 24 of the fixed plate 2. The first rack 22 is connected to the second sliding plate 4, and the second rack 23 is connected to the third sliding plate 5. The first rack 22 and the second rack 23 are located on the left and right sides of the gear 21, respectively, and the gear 21 meshes with both the first rack 22 and the second rack 23 simultaneously. When the gear 21 rotates, it can drive the second sliding plate 4 and the third sliding plate 5 to move longitudinally through the first rack 22 and the second rack 23, respectively. Due to the positional relationship between the gear 21 and the racks, the second sliding plate 4 and the third sliding plate 5 move in opposite directions, thus allowing them to move closer or further apart. The gear 21 can be designed with a large module to improve transmission efficiency and stability. The tooth profile of the rack can be selected as involute or spur according to actual needs to adapt to different working environments. To facilitate the rotation of gear 21, a rotating rod is connected to gear 21.
[0036] Furthermore, refer to Figure 3 To lock the rotation of gear 21 and prevent accidental rotation when not in operation, a toothed block 25 is slidably connected to the fixed plate 2. A return spring 26 is connected to the toothed block 25, with the other end of the return spring 26 connected to the fixed plate 2. The return spring 26 tends to bring the toothed block 25 closer to and mesh with gear 21. When gear 21 has rotated to its position, the toothed block 25, under the action of the return spring 26, can tightly fit against and mesh with gear 21, thereby locking the rotation of gear 21. When it is necessary to rotate gear 21, it is only necessary to overcome the elastic force of the return spring 26 to drive the toothed block 25 away from gear 21.
[0037] Specifically, refer to Figure 1The bubble-breaking mechanism 6 includes a support 61, a sliding seat 62, a mounting base 63, a roller cylinder 64, and a linear drive component 65. The support 61 can be a frame structure, welded from multiple metal rods, possessing high strength and stability. The sliding seat 62 is slidably connected to the support 61 longitudinally, and the linear drive component 65 is fixedly mounted on the support 61. In this application, the linear drive component 65 is an electric push rod, the output end of which is connected to the sliding seat 62. The mounting base 63 is slidably connected to the sliding seat 62 vertically, and the sliding seat 62 is equipped with an adjustment component for adjusting the height of the mounting base 63. The roller cylinder 64 is rotatably connected to the bottom of the mounting base 63. Specifically, the roller cylinder 64 is the core component of the bubble-breaking mechanism 6, and its surface can be provided with several sharp protrusions for puncturing bubbles on the foam surface. The shape of the protrusions can be conical, pyramidal, or serrated, and the specific shape can be selected according to the characteristics of the foam material. For example, for stiffer foam materials, pyramidal protrusions can be used to improve foam breaking efficiency; for softer foam materials, conical protrusions can be used to reduce damage to the foam surface. Furthermore, the roller cylinder 64 can be made of high-strength alloy steel and heat-treated to improve wear resistance and corrosion resistance.
[0038] The height of the mounting base 63 is adjusted by adjusting the component so that the roller cylinder 64 abuts against the upper surface of the workpiece. Then, the sliding seat 62 is moved by the linear drive component 65, so that the bubble breaking on the upper surface of the workpiece can be achieved smoothly.
[0039] The adjusting assembly between the mounting base 63 and the sliding base 62 includes a guide rod 66 and a threaded rod 67. The guide rod 66 is welded and fixed to the mounting base 63 vertically, and the threaded rod 67 is rotatably connected to the mounting base 63 about vertically. Both the guide rod 66 and the threaded rod 67 pass vertically through the sliding base 62, and the threaded rod 67 is threadedly connected to the sliding base 62. By rotating the threaded rod 67, the height of the mounting base 63 can be adjusted, thereby changing the distance between the roller cylinder 64 and the foam workpiece to accommodate the foam breaking operation of foam workpieces of different thicknesses.
[0040] The implementation principle of the foam breaking machine for headrest foam production in this application embodiment is as follows: During use, the foam workpiece is placed directly on the upper surface of the base 1. First, the handwheel 12 is rotated to drive the lead screw 11 to rotate, thereby driving the first sliding plate 3 to approach and press against the workpiece. Then, the rotating rod is rotated to drive the gear 21 to rotate. Through the meshing transmission of the gear 21 with the first rack 22 and the second rack 23, the second sliding plate 4 and the third sliding plate 5 are driven to approach each other and press against the longitudinal sides of the foam workpiece, thereby achieving clamping and limiting of the workpiece. The sliding connection of the first sliding plate 3, the second sliding plate 4, and the third sliding plate 5, combined with the setting of the first and second driving mechanisms, can limit workpieces of different lengths and widths, improving the problem that when foam breaking operations are required for workpieces of different sizes, the fixed limiting plates are not applicable, reducing the applicability of the foam breaking machine.
[0041] The above are all optional 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.
