Description

Technical Field

[0001] This invention belongs to the field of furniture installation equipment, and specifically relates to a bed mesh edge-sealing device. Background Technology

[0002] Spring mattresses have gained widespread market popularity due to their comfortable user experience. During the assembly process, a spring layer is arranged between the upper and lower mattress surfaces. This spring layer consists of multiple evenly spaced springs to ensure the mattress's elasticity. Additionally, a mattress net is installed on the sides of the mattress to connect the upper and lower mattress surfaces, ensuring the stability of the connection and maintaining uniform spacing between the sides of both surfaces.

[0003] Traditional mattress installation often involves manually installing the mattress one piece at a time around the bed using a hand-held edge-sealing gun. While this method ensures good installation integrity and quality, it is inefficient. Firstly, due to the elastic force of the springs, the upper and lower mattress surfaces cannot maintain a fixed connection, making it difficult to align the mattress with either surface. Secondly, to ensure the mattress remains vertical during the sequential alignment process, if it tilts after being connected to one surface, it cannot be properly aligned with the other unless rotated. However, this process disrupts the existing tension connection, requiring secondary fixing to complete the connection, thus resulting in low installation efficiency. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention proposes a bed net edging device that can effectively improve the installation efficiency of bed nets.

[0005] The technical solution adopted by the present invention to solve the above problems is as follows: a bed net edge-pressing device, including a support frame for supporting the bed, the bed including an upper bed surface on the upper end of the bed, a lower bed surface on the lower end of the bed, and a bed net on the side of the bed, the bed net being used to connect the upper bed surface and the lower bed surface, the lower bed surface abutting against the support surface of the support frame, the support frame also being provided with a pressure rod for pressing the upper bed surface, and an edge-pressing machine being provided on the side of the support frame, the edge-pressing machine being used to fix the upper end of the bed net to the upper bed surface and the lower end of the bed net to the lower bed surface, when fixing the bed net, the bed net being placed on a positioning frame, the positioning frame being used to ensure that the bed net is placed vertically so that the edge-pressing machine can accurately fix the bed net to the upper bed surface and the lower bed surface.

[0006] Compared with the prior art, the advantages of this invention are as follows: the lower bed surface abuts against the support frame, thus ensuring the lower bed surface remains stationary, while the upper bed surface is pressed by the pressure rod, thereby eliminating the freedom of the spring's movable end and ensuring the upward movement limit of the upper bed surface. Without other pressure, the upper bed surface can remain stationary, thus ensuring the stability and accuracy of the bed net when aligned with the upper and lower bed surfaces. Furthermore, through the design of the positioning frame, the bed net can be connected to the positioning frame. Simply ensuring the vertical placement of the positioning frame and the bed net's connecting surface guarantees the vertical state of the bed net during connection. This ensures that after the bed net is aligned with one side of the upper or lower bed surface, it remains vertical, eliminating the need for secondary fixing and allowing for alignment with the other side. This reduces the need for secondary fixing and improves installation efficiency.

[0007] As an improvement, the bed frame is composed of multiple support spring arrays. Each support spring includes a top edge fixedly connected to the upper bed surface, a bottom edge fixedly connected to the lower bed surface, and two adjustable edges located at the sides. Each support spring is formed by bending a steel wire. Each adjustable edge includes an adjusting ring and two adjusting sides. The adjusting ring is located on the axis of symmetry between the top and bottom edges and is spirally formed. One adjusting side is located between the top edge and the adjusting ring, and the other adjusting side is located between the bottom edge and the adjusting ring. The sum of the two adjusting sides is greater than the distance between the top and bottom edges. The distance between the top and bottom edges is adjusted by adjusting the distance between the two adjusting rings. This improvement also makes the support springs elastic, which not only ensures the overall elasticity of the spring bed but also provides adjustment space during installation, allowing for appropriate adjustment of the distance between the top and bottom edges to meet the connection requirements between the upper and lower bed surfaces.

[0008] As an improvement, the positioning frame is equipped with clamping wheel assemblies for clamping the net edge. There are two sets of clamping wheel assemblies, which are arranged along the axial direction of the net edge and are used to clamp both ends of the net edge. Each clamping wheel assembly includes multiple clamping wheels, which are arranged in an array along the height direction. Two adjacent clamping wheels are used to clamp the net edge for positioning. Through this improvement, the design of two clamping wheel assemblies can ensure the horizontality of the net edge when the power spring is connected to the positioning frame, thereby ensuring the accuracy of the connection between the net edge and the upper bed surface. The design of multiple clamping wheels can make the positioning frame more versatile and suitable for support springs of different specifications.

[0009] As an improvement, the positioning frame is further provided with a fixing connecting post for fixing the support spring to the positioning frame. Each fixing connecting post has multiple magnets for magnetically attracting the support spring. There are two fixing connecting posts in total, located on opposite sides of the two clamping wheel assemblies. A creasing station is provided between one fixing connecting post and the nearest clamping wheel assembly, and another creasing station is provided between the two clamping wheel assemblies. Through this improvement, after the support spring is connected to the upper and lower bed surfaces, it is necessary to ensure that the support spring can be quickly separated from the positioning frame. Therefore, a magnetic connection is used to ensure the support spring... The connection between the positioning frame and the spring is easy to connect and separate. The connection accuracy of the power spring is ensured by the clamping wheel assembly. The design of two fixed connecting columns attracts and fixes the two sides of the support spring to ensure the uniformity of the force on the support spring. The design of multiple magnets on the same fixed connecting column ensures that the same positioning frame can meet the attraction requirements of different support springs, making the positioning frame more versatile. The edge-trimming station is located between the fixed connecting column and a nearby clamping wheel assembly, or between two clamping wheel assemblies. This makes it less likely for the support spring to shift when connected to the upper and lower bed surfaces, resulting in a more accurate connection.

[0010] As an improvement, a reinforcing connecting rod is provided between the fixed connecting post and a nearby clamping wheel assembly to enhance the strength of the positioning frame. The reinforcing connecting rod has an adjustment hole. When adjusting the distance between the two adjusting sides, an external adjusting tool is inserted through the adjustment hole and into the adjusting ring. The external adjusting tool is limited to move within the adjustment hole. Through this improvement, the design of the reinforcing connecting rod can ensure the strength between the fixed connecting post and the clamping wheel assembly, preventing deformation of the fixed connecting post or the clamping wheel assembly. The design of the adjustment hole facilitates the adjustment of the adjusting ring by the external adjusting tool, while also limiting the external adjusting tool from over-adjusting the adjusting ring, preventing the adjusting ring from deforming and becoming irreversible.

[0011] As an improvement, the edge-trimming machine includes an edge-trimming gun, a material tray, and a material belt. The material belt is located between the edge-trimming gun and the material tray to transport the clip from the material tray to the edge-trimming gun. The edge-trimming machine is vertically connected to a movable frame, which is movable along the side of the support frame. With this improvement, the edge-trimming machine can be moved to different positions to connect the upper and lower mesh edges with the support springs respectively.

[0012] As an improvement, the side-firing gun includes an air inlet connector connected to an air source, a trigger assembly for engaging the magazine, and a trigger assembly for controlling the operation of the trigger assembly. A control valve is provided at the connection point of the air inlet connector, and a control piston is movably connected within the control valve. The side-firing gun contains a trigger air passage connecting the trigger assembly and the control valve, and a control air passage connecting the trigger assembly and the control valve. The control valve has an air inlet connected to the trigger air passage, a control air port continuously connected to the control air passage, and an exhaust port for venting. Under normal conditions, the air source continuously supplies air, which enters between the control piston and the control air passage, causing the control piston to pressurize the air inlet. The connector moves in the direction of movement and closes the channel between the air inlet connector and the air inlet, forming an airflow seal. When the trigger assembly is pressed, the control air passage is depressurized, the control piston moves in the direction of the control air passage, and the gas moves into the snap-lock assembly, driving the snap-lock assembly to engage the magazine. The trigger assembly resets, the control piston moves in the direction of the air inlet connector, and the gas in the snap-lock assembly moves from the air inlet to the exhaust port. The snap-lock assembly resets, completing one magazine snap-lock operation. Through the above improvement, the connection between the strafe gun's support spring and the top or bottom edge of the net is completed, ensuring that one trigger pull completes the fixing of one magazine. While maintaining continuous air intake, the waste of air intake is avoided.

[0013] As an improvement, the snap-fit ​​assembly includes a snap-fit ​​piston, a snap-fit ​​connecting rod, and a snap-fit ​​clamping block. The snap-fit ​​connecting rod connects the snap-fit ​​piston and the snap-fit ​​clamping block to allow for changes in the direction of movement between the snap-fit ​​piston and the snap-fit ​​clamping block. A snap-fit ​​return spring is fitted onto the snap-fit ​​piston. The trigger assembly includes a drive cylinder, a drive trigger, and a trigger piston. The drive cylinder drives the drive trigger to control the movement of the trigger piston to control the control air passage. A trigger return spring is provided on the trigger piston. Through these improvements, the snap-fit ​​assembly achieves its snap-fit ​​purpose and the trigger assembly achieves its control purpose.

[0014] As an improvement, the buckling piston is provided with a nail-stopping air passage on the side near the air inlet. The other end of the nail-stopping air passage is connected to a nail stopper. When the buckling assembly buckles the magazine, the nail stopper retracts, and the magazine moves along the material belt. When the buckling assembly resets, the nail stopper resets and abuts against the magazine, keeping the magazine stationary on the material belt. Through this improvement, the delivery control of the magazine is performed simultaneously with the buckling assembly. When the buckling operation of one magazine is completed, the nail stopper retracts. When the buckling clamping block resets, the material belt can deliver the next magazine to the buckling clamping block. Then the nail stopper resets, keeping the magazine stationary on the material belt, ensuring that the magazines enter the buckling clamping block one by one.

[0015] As an improvement, the pressure rod is moved vertically and connected to a corresponding adjusting stand, which is moved along the side of the support frame and connected to the support frame. Through this improvement, the pressure rod can be adapted to different sizes of beds by adjusting its settings. Attached Figure Description

[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, a bed netting edge-pressing device includes a support frame 1 for supporting the bed. The bed includes an upper bed surface 2 on the upper end, a lower bed surface 3 on the lower end, and a bed netting 4 on the side of the bed. The bed netting 4 connects the upper bed surface 2 and the lower bed surface 3. The lower bed surface 3 abuts against the support surface of the support frame 1. The support frame 1 is also provided with a pressure rod 5 for pressing the upper bed surface 2. An edge-pressing machine 6 is provided on the side of the support frame 1. The edge-pressing machine 6 is used to fix the upper end of the bed netting 4 to the upper bed surface 2 and the lower end of the bed netting 4 to the lower bed surface 3. When fixing the bed netting 4, the bed netting 4 is placed on a positioning frame 7. The positioning frame 7 is used to ensure that the bed netting 4 is placed vertically so that the edge-pressing machine 6 can accurately fix the bed netting 4 to the upper bed surface 2 and the lower bed surface 3.

[0028] like Figure 2 , Figure 3 As shown, the bed net 4 is composed of an array of multiple support springs 4.1. Each support spring 4.1 includes a net edge 4.1.1 fixedly connected to the upper bed surface 2, a lower net edge 4.1.2 fixedly connected to the lower bed surface 3, and two adjustable net edges 4.1.3 located at the sides. Each support spring 4.1 is formed by bending a single steel wire. Each adjustable net edge 4.1.3 includes an adjusting ring 4.1.4 and two adjusting edges 4.1.5. The adjusting ring 4.1.4 is positioned symmetrically to the net edge 4.1.1 and the lower net edge 4.1.2. On the shaft, the adjusting ring 4.1.4 is spirally formed. One adjusting edge 4.1.5 is located between the upper mesh edge 4.1.1 and the adjusting ring 4.1.4, and the other adjusting edge 4.1.5 is located between the lower mesh edge 4.1.2 and the adjusting ring 4.1.4. The sum of the two adjusting edges 4.1.5 is greater than the distance between the upper mesh edge 4.1.1 and the lower mesh edge 4.1.2. The distance between the upper mesh edge 4.1.1 and the lower mesh edge 4.1.2 is adjusted by adjusting the distance between the two adjusting rings 4.1.4.

[0029] The positioning frame 7 is equipped with clamping wheel assemblies 7.1 for clamping the net edge 4.1.1. There are two sets of clamping wheel assemblies 7.1, which are arranged along the axial direction of the net edge 4.1.1 and are used to clamp the two ends of the net edge 4.1.1 respectively. Each clamping wheel assembly 7.1 includes multiple clamping wheels 7.1.1, which are arranged in an array along the height direction. Two adjacent clamping wheels 7.1.1 are used to clamp the net edge 4.1.1 for positioning. The positioning frame 7 is also equipped with fixing connecting posts 7.2 for fixing the support spring 4.1 to the positioning frame 7. The fixing connecting posts 7.2 are equipped with multiple magnets 7 for magnetically attracting the support spring 4.1. 2.1 Two fixed connecting columns 7.2 are provided, respectively located on opposite sides of the two clamping wheel assemblies 7.1. A beveling station 7.3 is provided between one fixed connecting column 7.2 and the adjacent clamping wheel assembly 7.1, and a beveling station 7.3 is also provided between the two clamping wheel assemblies 7.1. A reinforcing connecting rod 7.4 to strengthen the positioning frame 7 is also provided between the fixed connecting column 7.2 and the adjacent clamping wheel assembly 7.1. The reinforcing connecting rod 7.4 is provided with an adjustment hole 7.5. When adjusting the distance between the two adjusting edges 4.1.5, an external adjusting tool is inserted through the adjusting hole 7.5 and connected to the adjusting ring 4.1.4. The external adjusting tool is limited and movable within the adjusting hole 7.5.

[0030] The positioning frame 7 is movably connected to a guide rail set along the side of the support frame 1. Multiple positioning frames 7 are set on the guide rail, and the number of positioning frames 7 and the distance between the positioning frames 7 can be adjusted according to different bed specifications.

[0031] like Figure 1 , Figure 4 As shown, the edge-trimming machine 6 includes an edge-trimming gun 6.1, a material tray 6.2, and a material belt 6.3. The material belt 6.3 is located between the edge-trimming gun 6.1 and the material tray 6.2 to transport the magazine 8 from the material tray 6.2 to the edge-trimming gun 6.1. The edge-trimming machine 6 is movably connected to a movable frame 10 along the vertical direction. The movable frame 10 is movably arranged along the side of the support frame 1.

[0032] like Figure 5-8As shown, the edge-firing gun 6.1 includes an air inlet 6.1.1 connected to an air source, an engagement assembly 6.1.2 for engaging the magazine 8, and a trigger assembly 6.1.3 for controlling the operation of the engagement assembly 6.1.2. A control valve 6.1.4 is provided at the connection point of the air inlet 6.1.1. A control piston 6.1.5 is movably connected within the control valve 6.1.4. The edge-firing gun 6.1 has an engagement air passage 6.1.6 connecting the engagement assembly 6.1.2 and the control valve 6.1.4, and a control air passage 6.1.7 connecting the trigger assembly 6.1.3 and the control valve 6.1.4. The control valve 6.1.4 has an air inlet 6.1.4.1 connected to the engagement air passage 6.1.6, a control air port 6.1.4.2 continuously connected to the control air passage 6.1.7, and an exhaust port 6.1.4.3 for exhausting air. Under normal conditions, the air source continuously supplies air, which enters between the control piston 6.1.5 and the control air passage 6.1.7. The control piston 6.1.5 moves towards the air inlet connector 6.1.1 and closes the passage between the air inlet connector 6.1.1 and the air inlet 6.1.4.1, forming an airflow seal. When the trigger assembly 6.1.3 is pressed, the control air passage 6.1.7 is depressurized, the control piston 6.1.5 moves towards the control air passage 6.1.7, and the air moves into the latching assembly 6.1.2, driving the latching assembly 6.1.2 to engage the magazine 8. The trigger assembly 6.1.3 resets, the control piston 6.1.5 moves towards the air inlet connector 6.1.1, and the air in the latching assembly 6.1.2 moves through the air inlet 6.1.4.1 to the exhaust port 6.1.4.3. The latching assembly 6.1.2 resets, completing one latching operation of the magazine 8.

[0033] like Figure 7As shown, the snap-fit ​​assembly 6.1.2 includes a snap-fit ​​piston 6.1.2.1, a snap-fit ​​connecting rod 6.1.2.2, and a snap-fit ​​clamping block 6.1.2.3. The snap-fit ​​connecting rod 6.1.2.2 connects the snap-fit ​​piston 6.1.2.1 and the snap-fit ​​clamping block 6.1.2.3 to allow for changes in the direction of movement between them. A snap-fit ​​return spring 6.1.2.4 is fitted onto the snap-fit ​​piston 6.1.2.1. Two snap-fit ​​clamping blocks 6.1.2.3 are provided; one is fixedly mounted, and the other is connected to the snap-fit ​​connecting rod 6.1.2.2. Under the action of the snap-fit ​​piston 6.1.2.1, the two snap-fit ​​blocks are engaged. The clips 6.1.2.3 move closer together, causing the magazine 8 to engage along the inner arc of the clip 6.1.2.3. The trigger assembly 6.1.3 includes a drive cylinder 6.1.3.1, a drive trigger 6.1.3.2, and a trigger piston 6.1.3.3. The drive cylinder 6.1.3.1 drives the drive trigger 6.1.3.2 to control the movement of the trigger piston 6.1.3.3 to control the control air passage 6.1.7. The trigger piston 6.1.3.3 is equipped with a trigger return spring 6.1.3.4. The drive cylinder 6.1.3.1 and the drive trigger 6.1.3.2 are connected by a connecting rod. When the drive cylinder 6.1.3.1 is driven, the drive trigger 6.1.3.2 performs corresponding pressing and reset.

[0034] like Figure 8 , Figure 9 As shown, the trigger piston 6.1.3.3 is provided with an air passage. When the drive trigger 6.1.3.2 is pressed, the trigger piston 6.1.3.3 moves towards the control air passage 6.1.7, thereby eliminating the contact between the trigger piston 6.1.3.3 and the sealing ring and allowing air to pass through. After the drive trigger 6.1.3.2 is reset, the trigger piston 6.1.3.3 moves away from the control air passage 6.1.7 under the action of the trigger return spring 6.1.3.4, compressing the sealing ring and forming a seal in the control air passage 6.1.7.

[0035] like Figure 7As shown, the snap-fit ​​piston 6.1.2.1 has a nail-stopping air passage 6.1.8 on the side near the air inlet 6.1.4.1. The other end of the nail-stopping air passage 6.1.8 is connected to a nail stopper 6.1.9. When the snap-fit ​​assembly 6.1.2 snaps into the clip 8, the nail stopper 6.1.9 retracts, and the clip 8 moves along the material strip 6.3. When the snap-fit ​​assembly 6.1.2 resets, the nail stopper 6.1.9 resets and abuts against the clip 8, making the clip 8 stationary on the material strip 6.3. The clips 8 are connected by flexible strips, so that the clips 8 on the material strip 6.3 form a whole. When two snap-fit ​​blocks 6.1.2.3 approach each other, they will cut the flexible strip on the current clip 8, separating the current clip 8 from the clip 8 on the material strip 6.3.

[0036] like Figure 1 As shown, the pressure rod 5 moves vertically and is connected to the corresponding adjusting stand 9. The adjusting stand 9 moves along the side of the support frame 1 and is connected to the support frame 1. There are four pressure rods 5 in total, which are used to press the four sides of the bed. Two of the pressure rods 5 move vertically and are connected to the adjusting stand 9. The adjusting stand 9 is equipped with a cylinder to ensure the pressure of the pressure rods 5. The other two pressure rods 5 are selected according to the specifications of the bed and placed between the two pressure rods 5 connected to the adjusting stand 9.

[0037] When edge trimming, the four sides of the bed need to be parallel to the four sides of the support frame 1, and the side of the bed to be edged needs to extend beyond the edge of the support frame 1 to facilitate edge trimming between the lower bed surface 3 and the support spring 4.1. Figure 1 In the middle, there are four edge-trimming machines 6, which are respectively located on the four sides of the support frame 1. However, because the bed is smaller than the support frame 1, only the four sides of the upper bed surface 2 can be edged. The two sides of the lower bed surface 3 need to be repositioned before edge-trimming can be performed.

[0038] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
