Description

Technical Field

[0001] This application relates to the field of soft packaging technology, and in particular to a soft padding covering device. Background Technology

[0002] Currently, upholstery technology is frequently used in the production of chairs, sofas, beds, and other furniture, especially in the production of upholstery for bar stools.

[0003] like Figure 1 As shown, existing padding generally includes a support plate 1, a sponge block 2, and an outer cover 3. When wrapping and binding the padding, the sponge block 2 is attached to the upper surface of the support plate 1, and then the outer cover 3 is used to wrap around the lower surface of the sponge block 2 and the support plate 1. The outer cover 3 is then manually tightened to compress the sponge 2 and shape it. Finally, the outer cover 3 is nailed to the lower surface of the support plate 1 using a nailing machine to fix the sponge block 2 and the outer cover 3.

[0004] Regarding the aforementioned technologies, since it is inconvenient to operate by manually pulling the outer skin taut and compressing the sponge block before nailing, improvements are needed. Utility Model Content

[0005] To facilitate stable and efficient wrapping and nailing of soft pads, this application provides a soft pad wrapping device.

[0006] The soft padding covering device provided in this application adopts the following technical solution: A cushion covering device includes: a support frame with a perforated area within its enclosure; an elastic layer covering the upper surface of the support frame; and a clamping member located above a support rod, the clamping member including a telescopic rod that extends and retracts along the height direction, the clamping member being used to press down a cushion support plate placed on the elastic layer.

[0007] By adopting the above technical solution, the support frame can support the elastic layer. The outer skin can be laid on the upper surface of the elastic layer first, followed by the sponge block and the support plate. Then, the support plate is pressed down by the telescopic rod of the clamping component. At this time, the elastic layer stretches and concaves, and the outer skin and sponge block are pressed tightly. The outer skin only needs to be slightly tightened to fit against the back of the support plate. Then, the outer skin can be fixed to the periphery of the support plate by a nailing machine. Finally, the telescopic rod is raised, and the covered soft pad can be removed. This achieves the effect of facilitating stable and efficient wrapping and nailing of the soft pad, while reducing labor intensity.

[0008] Preferably, it also includes a mounting bracket, wherein both the support frame and the clamping member are disposed on the mounting bracket.

[0009] By adopting the above technical solution, the support frame and the clamping component can be installed, ensuring that the clamping component is located above the support frame.

[0010] Preferably, the support frame is rotatably connected to the mounting bracket, the rotation axis of the support frame is set along the height direction, and a pressure plate is rotatably connected to one end of the telescopic rod near the support frame, the pressure plate and the rotation axis of the support frame are parallel to each other.

[0011] By adopting the above technical solution, the telescopic rod drives the pressure plate to move downward, and the pressure plate presses down on the support plate. Since it is necessary to nail the outer skin to the periphery of the support plate, the freely rotating support frame can simultaneously drive the soft pad to rotate, making it easy to adjust the nailing position of the soft pad to a position close to the operator, thus facilitating the nailing operation.

[0012] Preferably, the elastic layer is selected as elastic fabric.

[0013] By adopting the above technical solution, the elastic fabric has elastic deformation and recovery capabilities, which can compress the sponge block. The sponge experiences less force near the center of the pad and greater force around the perimeter, thus enabling better shaping of the pad.

[0014] Preferably, the elastic layer is detachably connected to the support frame.

[0015] By adopting the above technical solution, it is easy to disassemble and replace the elastic layer.

[0016] Preferably, the elastic layer covers the upper and lower periphery of the support frame, and a strip is provided on the lower periphery of the support frame to press down the edge of the elastic layer. The strip is detachably connected to the support frame by fasteners.

[0017] By adopting the above technical solution, after the strip is fixed by fasteners, the periphery of the elastic layer can be pressed and fixed to the periphery of the lower surface of the support frame, so as to realize the disassembly and replacement of the elastic layer.

[0018] Preferably, the fastener is selected as a bolt or screw, and the elastic layer has a strip hole on its periphery for the fastener to pass through.

[0019] By adopting the above technical solution, bolts or screws can lock the pressure plate to the support frame, and when the tension of the elastic layer changes, the strip hole can provide enough space for the fastener to pass through.

[0020] Preferably, the height of the pressure plate is adjustable.

[0021] By adopting the above technical solution, the clamping force of the telescopic rod on the support plate can be controlled, thereby improving its applicability.

[0022] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up the cooperation between the support frame, elastic layer and clamping parts, it is possible to make it easy to wrap and nail the soft pad stably and efficiently, and reduce the labor intensity. (2) By setting up an installation frame and a rotating support frame, it is easy to rotate the nailing position of the outer skin to a position close to the operator, which facilitates the nailing operation.

[0025] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0026] This application discloses a soft padding covering device. (Refer to...) Figure 2 and Figure 3 The cushion covering device includes a mounting frame 4, a support frame 5, an elastic layer 6, and a clamping element 7.

[0027] The support frame 5 is horizontally mounted on the mounting bracket 4. The support frame 5 is a square frame, ensuring that the area enclosed by the support frame 5 is open. The clamping component 7 includes a telescopic rod 71, which extends and retracts along the height direction. The clamping component 7 is mounted on the mounting bracket 4 and is located directly above the center of the support frame 5. The clamping component 7 is used to press down the soft pad support plate 1 placed on the elastic layer 6. In this embodiment, the clamping component 7 is selected as a vertically mounted cylinder, hydraulic cylinder, or electric cylinder, and the telescopic rod 71 is the telescopic component of the cylinder, hydraulic cylinder, or electric cylinder.

[0028] Among them, reference Figure 3 and Figure 4An elastic layer 6 covers the upper surface of the support frame 5. The elastic layer 6 is made of elastic fabric, which has a certain elastic deformation and recovery ability. The elastic layer 6 is detachably connected to the support frame 5 for easy replacement. When covering the pad, the outer skin 3, the sponge block 2, and the support plate 1 are stacked on the elastic layer 6 from bottom to top. Then, the telescopic rod 71 presses down on the support plate 1, causing the elastic layer 6 to concave. The sponge block 2 is also compressed and shaped. Then, the outer skin 3 is simply attached to the lower surface of the support plate 1 and fixed with a nailing machine. There is no need to manually tighten the outer skin 3 and cause the sponge block 2 to shrink. The shaping is more regular, and the labor intensity of covering is reduced.

[0029] Reference Figure 2 and Figure 5 The elastic layer 6 covers the upper and lower periphery of the support frame 5. A strip 8 is fixed to the lower periphery of the support frame 5, pressing down on the edge of the elastic layer 6. The strip 8 is detachably connected to the support frame 5 by several fasteners 9, which can be bolts or screws. The elastic layer 6 has spaced slotted holes 10 for the fasteners 9 to pass through. The length of the slotted holes 10 is perpendicular to the edge of the support frame 5 to which they are located. Bolts or screws can lock the strip 8 to the support frame 5. Furthermore, when the tension of the elastic layer 6 is adjusted, the slotted holes 10 provide sufficient space for the fasteners 9 to pass through, ensuring stable pressure of the strip 8 on the elastic layer 6.

[0030] The lower end of the support frame 5 is rotatably connected to the mounting bracket 4, and the rotation axis of the support frame 5 is set along the height direction; in this embodiment, the rotation axis of the support frame 5 is set vertically. Meanwhile, a pressure plate 11 is rotatably connected to the end of the telescopic rod 71 near the support frame 5. The pressure plate 11 and the telescopic rod 71 are connected by a bearing, and the rotation axis of the pressure plate 11 is parallel to the rotation axis of the support frame 5. The pressure plate 11 increases the force-bearing area between the telescopic rod 71 and the support plate 1, ensuring more stable compression of the support plate 1. Therefore, the support frame 5 can be directly rotated, causing the pressure plate 11, the support plate 1, the sponge block 2, and the outer skin 3 to rotate synchronously, making the nailing position of the outer skin 3 closer to the operator for convenient operation.

[0031] In some embodiments, the height of the pressure plate 11 is adjustable. Since the extension stroke of the telescopic rod 71 is generally fixed, the compression intensity on the support plate 1 can be controlled by adjusting the height of the pressure plate 11, thereby adjusting the compression plasticity of the sponge block 2. Specifically, a threaded sleeve 12 is coaxially fixed to the inner ring of the bearing. The threaded sleeve 12 is coaxial with and threadedly connected to the end of the telescopic rod 71.

[0032] The implementation principle of the soft pad covering device in this application embodiment is as follows: During operation, the threaded sleeve 12 is rotated to adjust the height position of the pressure plate 11; the outer skin 3, the sponge block 2 and the support plate 1 are stacked on the elastic layer 6 from bottom to top, and then the telescopic rod 71 presses down on the support plate 1, causing the elastic layer 6 to be concave. At this time, the sponge block 2 is squeezed and shaped. Then, the outer skin 3 is simply attached to the lower surface of the support plate 1. Finally, the outer skin 3 is fixed with a nailing machine. There is no need to manually tighten the outer skin 3 and cause the sponge block 2 to shrink, so as to achieve the effect of facilitating stable and efficient wrapping and nailing of the soft pad, and reducing labor intensity.

[0033] 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.
