[0002] Spring mattress is a commonly used furniture.

[0003] The existing spring mattress production is generally made by gluing multiple spring strips together. However, when the glued pocket spring strips are decomposed and recycled, the glue will pollute the environment, which is not in line with the current green and environmentally friendly ecological concept.

[0004] In order to comply with the concept of green production, there is a bed net combination device that realizes the welding positioning and displacement of the spring string by two sets of welding knives that alternately move up and down and forward and backward. At the same time, there is also a non-glue pocket spring bed core manufacturing device that uses a set of welding knives that can move forward and backward, up and down, and left and right to weld and position the spring string through a single set of welding knives.

[0005] The existing technology requires that the second row of spring strings be fed from the feeding area, and the first row of spring strings wait in the welding area, so that the two rows of springs are welded together by the welding mechanism before continuous production can be carried out.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0029] like Figures 1 to 5 The utility model is shown as a spring string feeding mechanism, comprising a feeding displacement mechanism 1, a conveying mechanism 2 and a dial 3. The spring string is input through the conveying mechanism 2, and the feeding displacement mechanism 1 drives the conveying mechanism 2 and the dial 3 to synchronously move left and right. The two dials 3 are arranged on both sides of the output end of the conveying mechanism 2 for clamping the spring for conveying, and the dial 3 can be displaced in the front and rear directions.

[0030] It should be noted that the feeding displacement mechanism 1 can adopt at least one of a linear drive, a cylinder pushing mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0031] like Figures 1 to 5 In the illustrated embodiment, the loading displacement mechanism 1 uses a linear drive, which has the advantages of fast and stable driving, and is conducive to continuous back and forth transportation.

[0032] When the utility model is in use, the spring string is input through the conveying mechanism 2, and the spring string is clamped and output through the dial 3. When the spring string needs to be conveyed to the welding area 101, the dial 3 is displaced forward so that the output position of the dial 3 is the welding area 101. At this time, the loading displacement mechanism 1 drives the conveying mechanism 2 and the dial 3 to displace along the left and right directions, and the dial 3 dials the spring string into the welding area 101 to form a row of spring strings.

[0033] After completing the input of the spring string at the welding area 101, when the dial needs to normally and continuously input the spring string to the feeding area 102, the dial 3 moves backward so that the output position of the dial 3 is the feeding area 102. At this time, the loading displacement mechanism 1 drives the conveying mechanism 2 and the dial 3 to move left and right synchronously. At this time, the loading displacement mechanism 1 drives the conveying mechanism 2 and the dial 3 to move along the left and right directions, and the dial 3 moves the spring string to the feeding area 102 to form a row of spring strings.

[0034] It should be noted that when the dial 3 completes inputting the spring string to the welding area 101 and moves backward, the dial 3 can be rotated synchronously to release the spring string to avoid the dial 3 pulling the spring string to move synchronously when moving backward.

[0035] The utility model has the advantages that the dial 3 capable of front-to-back displacement is provided, so that the conveying position of the dial 3 can be determined according to the front-to-back position, so that the dial 3 can input spring strings to different areas, which is beneficial to continuous production.

[0036] The dial further includes a mounting frame 31 , and the dial 3 is mounted on the feeding displacement mechanism 1 via the mounting frame 31 , wherein the mounting frame 31 is slidably connected to the feeding displacement mechanism 1 along the front-rear direction.

[0037] More specifically, by providing the mounting frame 31 , the displacement of the dial 3 is smooth.

[0038] It should be noted that the mounting bracket 31 can be mounted on the feeding displacement mechanism 1 by at least one of the following methods: a slider guide rod, an optical axis limit, a limit groove limit, etc.

[0039] It should be noted that the sliding connection between the mounting frame 31 and the loading displacement mechanism 1 only needs to satisfy the requirement that the mounting frame 31 can slide in the front-to-back direction, and the specific installation method is not specifically limited. The diagrams or instructions only show embodiments that can be implemented, but not the only implementation method.

[0040] Furthermore, a motor 32 for driving the dial 3 to rotate is disposed on the mounting frame 31 .

[0041] More specifically, by providing the motor 32, the dial 3 can rotate automatically, which helps the dial 3 to dial the spring string into the designated area.

[0042] Furthermore, the conveying mechanism 2 is a conveyor belt arranged opposite to each other, and the two dials 3 are arranged on both sides of the output end of the conveying mechanism.

[0043] More specifically, the clamping conveyor belt has the advantages of stable and accurate conveying, which is conducive to stably inputting the spring string between the two dials 3.

[0044] Furthermore, it also includes a driving mechanism 4, and the driving mechanism 4 is used to drive the dial 3 to move forward and backward relative to the conveying mechanism 2.

[0045] It should be noted that the driving mechanism 4 can adopt at least one of a linear drive, a cylinder pushing mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0046] More specifically, Figures 1 to 5In the illustrated embodiment, the driving mechanism 4 adopts a cylinder pushing mechanism, the cylinder body of the driving mechanism 4 is fixedly mounted on the mounting plate 12, and the piston rod of the driving mechanism 4 is fixedly connected to the mounting frame 31. At this time, the piston rod is extended and retracted to drive the mounting frame 31 to move back and forth in the front and rear directions, thereby driving the dial 3 to move back and forth.

[0047] Furthermore, the feeding displacement mechanism 1 includes a displacement mechanism 11 and a mounting plate 12 , and the displacement mechanism 11 drives the mounting plate 12 to displace in the left-right direction, and the conveying mechanism 2 and the dial 3 are both mounted on the mounting plate 11 .

[0048] More specifically, the displacement mechanism 11 can adopt at least one of a linear drive, a cylinder driving mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0049] like Figures 1 to 5 In the embodiment shown, the displacement mechanism 11 uses a linear drive, and the mounting plate 12 is connected to the output end of the linear drive. The displacement mechanism 11 drives the mounting plate 12 to move back and forth in the left and right directions.

[0050] Furthermore, it also includes a supporting plate 5 , and the dial 3 transports the spring string to the supporting plate 5 , and the lowest point of the dial 3 is higher than or level with the supporting surface of the supporting plate 5 .

[0051] More specifically, the lowest point of the dial 3 is higher than or equal to the supporting surface of the supporting plate 5 , thereby preventing the dial 3 from colliding with the supporting plate 5 when the dial 3 moves forward or backward.

[0052] Furthermore, it also includes an upper clamping plate 6 , which is arranged above the supporting plate 5 .

[0053] More specifically, by providing the upper clamping plate 6, the spring can be clamped by the upper clamping plate 6 and the supporting plate 5 after being input between the supporting plate 5 and the upper clamping plate 6, thereby ensuring that the spring is accurately positioned.

[0054] Furthermore, the upper clamping plate 6 can be displaced in the up and down directions.

[0055] More specifically, the upper clamping plate 6 can move up and down, so that when the dial 3 needs to move forward for transportation, the upper clamping plate 6 can be lifted up to avoid the dial 3.

[0056] In order to further understand the advantages of the present invention, Figures 6 to 9 The figure shows the use of the spring string feeding method of the utility model.

[0057] Figures 6 to 9The middle welding area 101 and the feeding area 102.

[0058] The specific usage includes the following steps:

[0059] S1: The dial 3 moves forward until the output position of the dial 3 is aligned with the welding area 101 (such as Figure 6 shown);

[0060] S2: The dial 3 and the conveying mechanism 2 move left and right synchronously so that the dial 3 conveys the spring string to the welding area 101 to form the first row of spring strings (such as Figure 7 shown);

[0061] S3: The dial 3 moves backward until the output position of the dial 3 is aligned with the feeding area 102 (such as Figure 8 shown);

[0062] S4: The dial 3 and the conveying mechanism 2 are synchronously displaced left and right so that the dial 3 conveys the spring string to the feeding area 102 to form a second row of spring strings (such as Fig. 9 shown);

[0063] S5: The spring string is transported forward until the feeding area 102 is empty;

[0064] Repeat S4 to S5 until the welding of one bed net is completed.

[0065] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the utility model.
