Description

Technical Field

[0001] This application relates to the field of mattress processing technology, and in particular to an automatic sealing device for mattress inner cores. Background Technology

[0002] In mattress manufacturing, the felt sealing of the mattress liner is a core process. Its function is to protect the filling and comfort layers from wear and tear by the spring mesh, while also providing sound insulation. Traditionally, the laying, cutting, wrapping, and sealing of the felt all rely on manual labor, resulting in low efficiency, high labor costs, and poor consistency. With the development of automation technology, some companies have attempted to introduce semi-automated equipment, such as simple robotic arms for handling or fixing devices for positioning. However, existing equipment still has many limitations. For example, cutting, wrapping, and sealing require multiple machines to complete the process in stages, with workflow coordination relying on manual intervention, leading to low efficiency; the felt may not be securely fixed and is prone to displacement; cutting dimensions may have large deviations; and sealing seams may not be tight, affecting the quality of the finished product. Furthermore, the equipment structure is rigid, making it difficult to adapt to mattress liner sizes or shapes, and modification costs are high.

[0003] Based on these issues, mattress filling sealing is still a relatively inefficient part of the entire production process that is prone to quality problems. Therefore, it is necessary to design a device that can automate the mattress filling sealing process and be compatible with the production line. Utility Model Content

[0004] The main purpose of this application is to provide an automatic sealing device for mattress inner filling, which aims to solve the problems of high manual dependence and low efficiency in the existing mattress inner filling sealing work.

[0005] To achieve the above objectives, this application proposes an automatic sealing device for mattress inner filling, comprising:

[0006] The stage includes multiple modules, with adjacent modules hinged together. Each module is used to place a covering material. Each module has several telescopic pins on its surface close to the covering material. The telescopic pins are used to insert into and fix the covering material.

[0007] Several closing drive components, each of which is used to rotate the corresponding module so that the covering material encloses the mattress core;

[0008] Multiple sealing elements are slidably disposed on corresponding modules. The sealing elements are used to slide along the modules to seal the seam between the mattress inner core and the covering material when the covering material is covering the mattress inner core.

[0009] For example, in the automatic sealing device for mattress inner core provided in at least one embodiment of this application, multiple modules include a central module and multiple sealing modules. The multiple sealing modules rotate relative to the edge of the central module so that the covering material forms a shape that seals the mattress inner core.

[0010] For example, in at least one embodiment of the automatic sealing device for mattress inner core provided in this application, a cover plate is also included. The cover plate is located above the platform and its shape matches the unfolded plane of the platform. An annular groove is provided around the periphery of the cover plate, and a cutter that can move along the annular groove is mounted on the annular groove.

[0011] For example, in the automatic sealing device for mattress inner liner provided in at least one embodiment of this application, the cover plate is connected to the pressing drive member, and the pressing drive member presses and fixes the covering material to the platform.

[0012] For example, in the automatic sealing device for mattress inner liner provided in at least one embodiment of this application, the pressing drive is fixedly connected to the rotating mechanical arm, and the rotating mechanical arm rotates relative to the platform to move the cover away from or closer to the platform.

[0013] For example, in the automatic sealing device for mattress inner lining provided in at least one embodiment of this application, the closing drive component is a hydraulic device or a pneumatic device, including a piston rod and a cylinder, wherein the piston rod and the cylinder are respectively hinged to two adjacent modules.

[0014] For example, in the automatic sealing device for mattress inner lining provided in at least one embodiment of this application, the cutter is mounted on the annular groove via a mounting base, and the cutting depth is adjusted via the mounting base.

[0015] For example, in the automatic sealing device for mattress inner core provided in at least one embodiment of this application, the telescopic needle is inclined at a preset angle on the surface of each module, and the preset insertion depth is 10% to 80% of the needle length.

[0016] For example, in the automatic mattress filling sealing device provided in at least one embodiment of this application, the two wings of the platform are provided with a set of conveying wheels, and the head of the platform is provided with a support rod. The covering material is conveyed to the platform through the support rod and the conveying wheels.

[0017] For example, in at least one embodiment of the automatic sealing device for mattress inserts provided in this application, a conveyor belt and a gripping robotic arm are also included. The conveyor belt is used to transport the mattress insert, and the gripping robotic arm is used to transfer the mattress insert to the loading platform.

[0018] Compared with existing technologies, the automatic mattress filling sealing device of this application has at least the following beneficial effects: Through the synergy of a modular platform and sealing components, highly efficient automation and precise control of mattress filling sealing are achieved. The platform employs an unfoldable and rotating sealing module, allowing the filling to fit tightly against all surfaces of the mattress filling. Inclined telescopic pins on the surface of each module dynamically insert and fix the filling during installation, ensuring stability and improving sealing accuracy during cutting and wrapping. Furthermore, the sealing components slide along the modules to form a movement trajectory, ensuring the sealing covers multiple critical seams of the filling, guaranteeing edge integrity and strength. This automatic mattress filling sealing device achieves unmanned, high-precision, and high-efficiency mattress filling sealing, which is beneficial for improving the efficiency of mattress manufacturing.

[0031] In one embodiment of the automatic sealing device for mattress inner core provided in this application, the sealing device includes: a platform 1 and a plurality of sealing components 15, wherein the platform 1 includes six unfoldable modules, and each module has a plurality of telescopic pins 2 on its upper surface for inserting and fixing the covering material 9; adjacent modules are hinged together by a rotating shaft 16; adjacent modules are also provided with a closing drive component, which causes each module to rotate relative to the adjacent modules and form a sealing of the mattress inner core; there are at least three sealing components 15, which are slidably mounted on the platform 1 by means of straight slide grooves 17 provided on the edges of at least three modules, and move along the straight slide grooves 17 in the state where each module forms a sealing, to seal the seam between the mattress inner core and the covering material 9.

[0032] Specifically, such as Figure 1 As shown, the platform 1 is a cuboid—that is, the unfolded shape of the mattress inner core—and includes six modular plates corresponding to each face of the mattress inner core. Among these modules are a bottom center module and multiple enclosing modules. The enclosing modules rotate relative to the edge of the bottom center module to allow the covering 9 to... Figure 2 The diagram shows the shape that forms the inner core of the mattress. Furthermore, the multiple modules also include a sealing module, which is hinged to any of the sealing modules. After each sealing module and the bottom center module form a sealed state, the open opening is sealed to achieve full coverage.

[0033] It should be noted that the platform, as a component that supports the covering and mattress inner core, is supported at its bottom by support columns or frames, for example, using... Figure 1 , 2 as well as Figure 4 The form shown is implemented.

[0034] Each module plate has movable telescopic pins 2 evenly arranged on its upper surface. The telescopic pins 2 extend and pierce the covering material 9 to fix the covering material 9 on the platform 1 and prevent it from shifting. After the sealing work is completed, the telescopic pins 2 retract and release the covering material 9 from the fixation.

[0035] Preferably, the telescopic needle 2 is inclined at a preset angle on the surface of each module, and the preset insertion depth is 10% to 80% of the needle length. For example, the telescopic needle 2 is inserted at a 30° angle (the angle between the needle tip direction and the horizontal surface of the platform 1) for 40% of the needle length, which can effectively fix the covering material 9 such as cotton felt, without piercing the mattress core and causing damage.

[0036] Each pair of adjacent module plates is hinged by a pivot or other means, so that they can be rotated relative to each other to form a three-dimensional shape. At the same time, the lower surface edges of the adjacent module plates are provided with corresponding hinge seats and connected by hydraulic rods 14 (or pneumatic rods), which constitute the closing drive component in this embodiment. Under the cooperation of the extension and retraction of hydraulic rods 14 (or pneumatic rods), the hinge form and the hinge form between modules, one module plate can be rotated relative to the module plate it is connected to, so as to complete the solid closing of the unfolded shape of the platform 1.

[0037] On the outline edges of the three module plates that make up the stage 1, there are straight grooves for the installation and movement of the sealing component 15. The sealing component 15 can work close to the edge of the sealing by rotating the rotating mechanism. When working, it moves along the straight groove to completely seal the entire edge.

[0038] It is understandable that, based on the assembly result of the platform 1 as a cuboid unfolded diagram, there are eight sides that need to be sealed when the covering material 9 is wrapped around the mattress inner core. In actual production, it is not necessary to completely seal every side. In this embodiment, the sealing component 15 can complete the sealing of one side by moving on the straight groove, and three sealing machines can correspond to at least three sides, which is sufficient to basically complete the sealing of the mattress inner core. Preferably, the single straight line of the straight groove can also be designed as a U-shaped line, such as... Figure 2 As shown, this allows the encapsulating element 15 to turn on the straight groove to encapsulate more sides.

[0039] In the embodiments of this application, the sealing component 15 may be a sewing machine head, a stapler gun, or a heat sealing device; if necessary, multiple components may be selected and combined as needed, or replaced by a detachable installation method.

[0040] Furthermore, the components of this application, such as the telescopic pin 2 and the closing drive component, which are not specified in quantity, can be selected by those skilled in the art as needed. It should be understood that any technical solution formed by any variation or combination of quantities without achieving unexpected technical effects should be within the scope of protection claimed in this application.

[0041] Taking cotton felt sealing as an example, the cotton felt is first laid on the platform 1, and the telescopic needle 2 extends and pierces the cotton felt to fix it. Then, the mattress inner liner is placed on the platform 1. Under the action of the hydraulic rod 14 (or pneumatic rod) and other closing drive components, the various module plates of the platform 1 rotate and close to form a "box" that completely wraps all sides of the mattress inner liner. The cotton felt attached to the platform 1 can also adhere to all sides of the mattress inner liner under the closing action. Then, the sealing component 15 approaches the edge of the mattress inner liner to seal and connect the cotton felt. The automatic mattress inner liner sealing device of this embodiment realizes the automation and high efficiency of mattress inner liner sealing, which is conducive to improving the efficiency of mattress manufacturing and processing.

[0042] In one embodiment, the automatic sealing device for mattress inner core of this application further includes a cover plate 3, which is located above the platform 1. The shape of the cover plate 3 matches the unfolded plane shape of the platform 1. The periphery of the cover plate 3 is provided with an annular groove 5, and a cutter 4 that can move along the annular groove 5 is mounted on it.

[0043] In this embodiment, the cover plate 3 can further improve the automation of the sealing device, that is, it can cut the covering material 9 without pre-processing the covering material 9 before sealing. For example, laying a whole piece of cotton felt on the platform 1 and pressing it down with the cover plate 3 is beneficial to the penetration rate of the telescopic needle 2 into the cotton felt, making the fixing effect better. The annular groove 5 and the cutter 4 provided on the side of the cover plate 3 can cut off the excess part of the cotton felt, leaving a shape suitable for wrapping, which can directly enter the next process on the platform 1.

[0044] Furthermore, the cutter 4 is mounted on the annular groove 5 via a mounting base, and the cutting depth is adjusted via the mounting base. The mounting base slides on the annular groove 5, thereby driving the movement of the cutter 4. Possibly, the mounting base is controlled by an external program, and the mounting position of the cutter 4 can be moved up and down to facilitate cutting and depth adjustment. It can also be moved left and right to facilitate precise cutting.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, the cover plate 3 can also be connected to the clamping drive 7, which clamps and fixes the covering 9 to the platform 1. For example, the cover plate 3 can be connected to a hydraulic device, which uses hydraulic drive to compact the covering 9 on the platform 1, resulting in stable operation and better performance.

[0046] To facilitate smooth operation, the clamping drive 7 is fixedly connected to the rotating robotic arm 6, which rotates relative to the platform 1 to move the cover plate 3 away from or closer to the platform 1.

[0047] For example, a rotating robotic arm 6 is set on one side of the platform 1, and a hydraulic device is installed at the far end. The hydraulic device is fixedly connected to the cover plate 3. The rotating robotic arm 6 lifts the cover plate 3 by rotating or places the cover plate 3 above the platform 1, and uses the hydraulic device to make the cover plate 3 close to the platform 1 to form a compaction effect.

[0048] In this embodiment, the cover plate 3 and the matching structure can be used to process the packaged material 9 in a coordinated manner, further improving the automation level of the sealing device of this application and making it more suitable for the needs of assembly line production.

[0049] In one embodiment, the two wings of the platform 1 are provided with a set of 10 conveyor wheels 8, and the head of the platform 1 is provided with a support rod. The covering material 9 is conveyed to the platform 1 through the support rod and the conveyor wheels 10.

[0050] like Figure 1 and Figure 3 As shown, the two wings of the platform 1 are equipped with two layers of several sets of conveyor wheels 10. When the packaged item 9 is conveyed to the platform 1, it passes through the gap between the two layers of conveyor wheels 10, which helps to stabilize the conveying of the packaged item 9, and finally lays flat on the platform 1 for the telescopic pin 2 to fix it. It can be understood that a single layer of conveyor wheels 10 can achieve the same effect, but the previous implementation method is preferred.

[0051] Similarly, the covering material 9 can also be conveyed to the platform 1 via support rods and conveyor wheels 10 to enhance the continuity, stability, and automation of production. For example, parallel conveyor wheels 10 can be installed at the head or front end of the platform 1, allowing the covering material 9 to pass through the gap and enter the platform 1, while the conveyor wheels 10 sets 8 pass through both sides to limit conveying fluctuations or deviations.

[0052] In another embodiment, the automatic sealing device for mattress inserts also includes a conveyor belt 11 and a gripping robotic arm 12, wherein the conveyor belt 11 is used to transport the mattress inserts and the gripping robotic arm 12 is used to transfer the mattress inserts to the platform 1.

[0053] like Figure 5 As shown, two conveyor belts 11 are respectively arranged at the head and tail of the platform 1, and a transfer robotic arm is arranged between the two conveyor belts 11. The gripper 13 of the transfer robotic arm can be used to grasp the mattress inner core. Through the arrangement of the conveyor belts 11 and the transfer robotic arm, the automatic mattress inner core sealing device of this application can be completely integrated into the production line.

[0054] Below, in conjunction with the foregoing embodiments and Figure 5 The automatic sealing process of the sealing device in this application is described according to the production process:

[0055] 1. The covering material 9 (such as cotton felt) is transported to the platform 1 via the parallel conveyor wheel 10 and the set 8 of the conveyor wheels 10;

[0056] 2. The covering material 9 is pressed by the cover plate 3 (rotating robotic arm 6 and pressing drive 7), and the position of the covering material 9 is fixed by the telescopic pin 2;

[0057] 3. The cutter 4 cuts out the pre-defined shape of the covering material 9 along the annular groove 5;

[0058] 4. The transfer robotic arm grabs the mattress inner core conveyed by the conveyor belt 11 and places it on the cut platform 1 (the platform 1 has been covered with the covering material 9);

[0059] 5. The platform 1 drives each module to wrap the mattress inner core through the closing drive component, and the sealing component 15 moves along the slide to complete the sealing.

[0060] 6. After the packaging is completed, the transfer robotic arm will transfer the finished product to another conveyor belt 11 to enter the next process.

[0061] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
