Description

Technical Field

[0001] The utility model belongs to the technical field of bed core production, and in particular relates to a device for manufacturing a pocket spring bed core. Background Art

[0002] The development of pocket spring mattress core technology is aimed at improving the comfort and durability of the mattress core. The independent pocket spring system achieves more precise support and pressure distribution to various parts of the body by independently encapsulating each spring in a small pocket made of non-woven fabric or other fabrics.

[0003] The traditional manufacturing method uses hot-melt adhesive to secure these individual spring units together, creating a continuous and stable bed net structure. However, this process not only consumes a large number of consumables (especially hot-melt adhesive), but also suffers from production inefficiencies, such as long preheating times, high glue box maintenance costs, and a work environment susceptible to contamination from glue spillage. Furthermore, the loading mechanism cannot evenly align the spring string when delivering it to the workbench, resulting in uneven pocket springs at both ends of the string, which compromises the aesthetics of the finished bed core.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The utility model hopes to provide a pocket spring mattress core manufacturing device, the specific scheme is as follows:

[0006] A device for manufacturing a pocket spring bed core includes a workbench, a feeding mechanism, a welding mechanism, and a correction mechanism. The feeding mechanism reciprocates in the horizontal direction and is used to convey a spring string to the workbench. The spring string includes a plurality of pocket springs connected in sequence. The welding mechanism includes an ultrasonic die assembly and a sealing knife assembly. The ultrasonic die assembly cooperates with the sealing knife assembly to complete the welding between the spring strings. After welding, the spring strings form a bed core. The correction mechanism includes a first driving member and a toggle member. The first driving member drives the toggle member to correct the position of the pocket springs at the end of the spring string.

[0007] The pocket spring bed core manufacturing equipment includes a toggle mechanism, which is arranged on the lower side of the workbench. The toggle mechanism is arranged to be able to move forward, backward, left, right, up and down. The toggle mechanism includes several toggle rods, and the several toggle rods are used to toggle the bed core to move; the sealing knife assembly includes a first sealing knife assembly and a second sealing knife assembly, both of which are located on the upper side of the workbench, and the first sealing knife assembly and the second sealing knife assembly can move up and down to weld with the ultrasonic die assembly.

[0008] The sealing knife assembly includes a first sealing knife assembly and a second sealing knife assembly. The first sealing knife assembly is located on the upper side of the workbench, and the second sealing knife assembly is located on the lower side of the workbench. The first sealing knife assembly and the second sealing knife assembly can move up and down to weld with the ultrasonic die head assembly, or move back and forth to move the bed core.

[0009] There are two correction mechanisms, which are respectively arranged on both sides of the workbench.

[0010] The first driving member includes a first cylinder and a second cylinder. The second cylinder is driven by the first cylinder. The second cylinder drives the connecting plate to move. The toggle member is arranged on the connecting plate. The toggle member adopts an L-shaped toggle plate.

[0011] The ultrasonic die assembly is configured to be movable up, down, left, and right. The ultrasonic die assembly includes a plurality of ultrasonic dies that can be movable left and right in a horizontal direction.

[0012] The pocket spring bed core manufacturing equipment includes a cutting mechanism, which moves synchronously with the ultrasonic die assembly; the cutting mechanism includes a cutting groove, a cutting knife and a second driving member, and the second driving member drives the cutting knife close to the cutting groove to cut the spring string into an independent bed core.

[0013] The cutting mechanisms are provided in two and are respectively arranged on both sides of the ultrasonic die assembly.

[0014] The feeding mechanism includes a third driving member and a conveying member. The conveying members are arranged in pairs, and a feeding channel is formed between the paired conveying members. At least one of the conveying members is an active member, and the active member includes at least one of a ratchet, a roller, and a conveyor belt. The third driving member is used to drive the active member to convey the spring string.

[0015] The feeding mechanism includes a limiting member, and the limiting member and the conveying member together form a feeding channel.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) The present application provides a correction mechanism, namely a first driving member and a toggle member. The first driving member drives the toggle member to move in the front, back, left, and right directions to correct the position of the pocket springs at the ends of the spring string, thereby aligning the pocket springs at both ends of the spring string and improving the aesthetics of the resulting bed core.

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with specific implementation methods.

[0030] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with respect to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solutions provided by the present invention.

[0031] like Figures 1-9 As shown, a pocket spring bed core manufacturing device includes a workbench 1, a feeding mechanism 2, a welding mechanism and a correction mechanism 4. The feeding mechanism 2 reciprocates in the horizontal direction and is used to convey a spring string 5 onto the workbench 1. The spring string 5 includes a plurality of pocket springs connected in sequence; the welding mechanism includes an ultrasonic die assembly 33 and a sealing knife assembly. The ultrasonic die assembly 33 is close to the sealing knife assembly and cooperates with each other to complete the welding between the spring strings 5. The welded spring strings 5 ​​form a bed core 6; the correction mechanism 4 includes a first driving member 41 and a toggle member 42. The first driving member 41 drives the toggle member 42 to correct the position of the pocket springs at the end of the spring string 5.

[0032] The pocket spring bed core manufacturing equipment also includes a toggle mechanism, which is arranged on the lower side of the workbench 1 (to avoid collision between the welding mechanism and the toggle mechanism during welding operation). The toggle mechanism is arranged to be able to move forward, backward, left, right, up and down. The toggle mechanism includes several toggle rods 7, and the several toggle rods 7 are used to toggle the bed core 6 to move; the sealing knife assembly includes a first sealing knife assembly 31 and a second sealing knife assembly 32. The first sealing knife assembly 31 and the second sealing knife assembly 32 are both located on the upper side of the workbench 1, and the first sealing knife assembly 31 and the second sealing knife assembly 32 can move up and down to weld with the ultrasonic die head assembly 33.

[0033] The sealing knife assembly includes a first sealing knife assembly 31 and a second sealing knife assembly 32. The first sealing knife assembly 31 is located on the upper side of the workbench 1, and the second sealing knife assembly 32 is located on the lower side of the workbench 1. The first sealing knife assembly 31 and the second sealing knife assembly 32 can move up and down to weld with the ultrasonic die head assembly 33, or move back and forth to move the bed core 6.

[0034] Two calibration mechanisms 4 are provided, one on each side of the workbench 1. The first drive member 41 comprises a first cylinder 411 and a second cylinder 412. The second cylinder 412 is driven by the first cylinder 411, which in turn drives a connecting plate 413. The toggle member 42 is mounted on the connecting plate 413 and is an L-shaped toggle plate. The ultrasonic die assembly 33 is configured to be movable vertically and horizontally, and includes multiple ultrasonic dies that can be moved horizontally.

[0035] The pocket spring core manufacturing apparatus also includes a cutting mechanism 8, which moves synchronously with the ultrasonic die assembly 33. The cutting mechanism 8 includes a cutting slot 81, a cutting blade 82, and a second driving member 83. The second driving member 83 drives the cutting blade 82 toward the cutting slot 81 to cut the spring string 5 into individual spring cores 6. Two cutting mechanisms 8 are provided, one on either side of the ultrasonic die assembly 33. Depending on the desired specifications of the spring core 6, one cutting mechanism 8 can be selected to cut the spring string 5. The feeding mechanism 2 includes a third driving member and a conveying member 21. The conveying members 21 are arranged in pairs, forming a feed channel 22 between the paired conveying members 21. At least one of the conveying members 21 is an active member, including at least one of a ratchet, a roller, and a conveyor belt. The third driving member drives the active member to convey the spring string 5. The feeding mechanism 2 includes a stopper 23, which together with the conveying member 21 form the feed channel 22.

[0036] Here’s how it works: Example 1

[0037] The pocket spring bed core manufacturing equipment includes a toggle mechanism that can move forward, backward, left, right, up and down, and the toggle mechanism includes several toggle rods 7, and the several toggle rods 7 are used to toggle the bed core 6 to move; the sealing knife assembly includes a first sealing knife assembly 31 and a second sealing knife assembly 32, and the first sealing knife assembly 31 and the second sealing knife assembly 32 are both located on the upper side of the workbench 1, and the first sealing knife assembly 31 and the second sealing knife assembly 32 can move up and down to be welded with the ultrasonic die head assembly 33.

[0038] Specifically, first, the feeding mechanism 2 reciprocates in the horizontal direction to transport the spring string 5 to the workbench 1, and then the correction mechanism 4 is used to correct the position of the pocket spring at the end of the spring string 5, that is, the first cylinder 411 drives the second cylinder 412 to the right, and at the same time, the second cylinder 412 drives the connecting plate 413 and the L-shaped toggle plate to move forward, and then the first cylinder 411 and the second cylinder 412 are used to move the L-shaped toggle plate close to the pocket spring at the end of the spring string 5, so that the position of the pocket spring at the end of the spring string 5 is aligned (such as Figure 5-Figure 8 As shown). It should be noted that the correction mechanism 4 only operates when it is on the opposite side of the feeding mechanism 2, not when the correction mechanisms 4 on both sides are activated. When the feeding mechanism 2 reaches the correction mechanism 4, the correction mechanism 4 needs to be withdrawn to prevent collision. For example, when the feeding mechanism 2 is on the left, the correction mechanism 4 on the right will correct the position of the last spring at the end of the spring string 5. When the feeding mechanism 2 moves from the left to the right and the spring string 5 is about to reach the correction mechanism 4, the correction mechanism 4 needs to be withdrawn to prevent collision.

[0039] At this point, the first row of spring strings 5 ​​has been arranged, and the lever 7 is then used to move the first row of spring strings 5 ​​one end distance toward the rear end of the workbench 1. Following the above steps, the second row of spring strings 5 ​​is conveyed and processed by the correction mechanism 4, and then the first sealing knife assembly 31 or the second sealing knife assembly 32 is driven up and down to be welded to the ultrasonic die assembly 33. The welding mode between the first sealing knife assembly 31 and the second sealing knife assembly 32 and the ultrasonic die assembly 33 is alternating welding, that is, the first sealing knife assembly 31 and the second sealing knife assembly 32 are arranged at intervals; the first row of spring strings 5 ​​and the second row of spring strings 5 ​​are welded via the first sealing knife assembly 31 and the ultrasonic die assembly 33, while the second row of spring strings 5 ​​and the third row of spring strings 5 ​​are welded via the second sealing knife assembly 32 and the ultrasonic die assembly 33.

[0040] After each welding operation, the spring string 5 is moved toward the rear of the workbench 1 using a lever 7 (the lever 7 can move forward, backward, left, right, and up and down, so it won't interfere with the ultrasonic welding process) to allow the loading mechanism 2 to stably deliver the spring string 5 to the workbench 1. After multiple rows of spring strings 5 ​​are welded to form a bed core 6 of a certain size, the cutting mechanism 8 cuts the spring string 5 delivered from the pocket spring loading mechanism 2, forming a single bed core 6 on the workbench 1. Example 2

[0041] The sealing knife assembly in the pocket spring bed core manufacturing equipment only includes the first sealing knife assembly 31 and the second sealing knife assembly 32, and the toggle mechanism is omitted, wherein the first sealing knife assembly 31 is located on the upper side of the workbench 1, and the second sealing knife assembly 32 is located on the lower side of the workbench 1. The first sealing knife assembly 31 and the second sealing knife assembly 32 can move up and down to weld with the ultrasonic die assembly 33, or move back and forth to toggle the bed core 6. That is, by setting the first sealing knife assembly 31 and the second sealing knife assembly 32 to move up and down and back and forth, the spring string 5 can be welded while also performing the toggle operation.

[0042] Specifically, the steps of loading, calibrating, welding, and cutting are the same as those in Example 1. The difference is that after the first row of spring strings 5 ​​are arranged, the first sealing knife assembly 31 or the second sealing knife assembly 32 is used to move the first row of spring strings 5 ​​toward the rear end of the workbench 1. After the second row of spring strings 5 ​​is conveyed according to the above steps and processed by the calibration mechanism 4, if the first sealing knife assembly 31 is driven to move up and down to weld with the ultrasonic die assembly 33, the second sealing knife assembly 32 is used to move back and forth to move the bed core 6 toward the rear end of the workbench 1; conversely, if the second sealing knife assembly 32 is driven to move up and down to weld with the ultrasonic die assembly 33, the first sealing knife assembly 31 is used to move back and forth to move the bed core 6 toward the rear end of the workbench 1.

[0043] The application sets the correction mechanism 4, that is, the first driving member 41 and the poking member 42, the first driving member 41 drives the poking member 42 to move in the front-back and left-right directions, is used for correcting the pocketed spring position of the spring string 5 end, thereby arranging the pocketed springs at both ends of the spring string 5 to be flat, and the appearance of the prepared bed core 6 is improved; meanwhile, the feeding mechanism 2 reciprocates in the horizontal direction, the sealing cutter assembly and the ultrasonic wave die assembly 33 are close to each other, the adjacent spring strings 5 are welded by ultrasonic waves instead of hot melt adhesive, the problems such as hot melt adhesive pollution are avoided, the overall equipment structure is simple, the process is simplified, the preparation process is fully automatic, and the production efficiency is higher.

[0044] The above embodiment is only used for explaining the inventive concept of the utility model, rather than limiting the protection of the utility model, and any non-essential change of the utility model by using the concept falls within the protection scope of the utility model.
