Description

Technical Field

[0001] This utility model relates to the field of bag spring production machinery technology, specifically to a bag spring insertion and welding mechanism. Background Technology

[0002] In the existing process of producing pocket springs, the springs need to be compressed and fed into non-woven bags, and then the non-woven bags are sealed to form a continuous bag of springs.

[0003] The production of pocket springs requires a bag-feeding welding mechanism. Existing bag-feeding welding mechanisms generally include a clamping conveyor belt and a welding mechanism. The clamping conveyor belt feeds the pocket springs into the non-woven bag, and a welding mechanism is located at the output end of the clamping conveyor belt to weld and seal the non-woven bag. However, this method has a problem: at the exit of the clamping conveyor, the spring is not easily detached from the clamping conveyor.

[0004] To address the issue of springs being difficult to detach from the clamping and conveying mechanism, a bag spring welding and feeding mechanism (CN 210789643 U) has been developed. This mechanism utilizes two sets of annular conveying mechanisms with levers at the output end of the clamping and conveying mechanism. These levers clamp and push the springs inside the fabric bag, while a welding mechanism with a fixed opening and closing position is provided. After the levers push the springs away from the clamping and conveying mechanism, they pass through the welding mechanism, which then opens and closes to weld the non-woven fabric bag. However, this structure has several problems: 1. The levers are located on one side of the spring, and the welding position of the welding mechanism is also on the same side of the spring. This could potentially interfere with the welding mechanism; 2. Each time, the welding mechanism needs to be fully welded before reopening and feeding the next spring, resulting in a long interval and hindering rapid production. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention aims to provide a bag spring insertion welding mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bag-packing spring insertion and welding mechanism includes a clamping and conveying mechanism, a circulating conveying mechanism, and a welding mechanism;

[0008] A clamping and conveying mechanism is used to keep the spring compressed when feeding it into the cloth bag;

[0009] A circulating conveying mechanism includes at least one circulating drive mechanism and a suction cup. Each of the circulating drive mechanisms is provided with at least one suction cup for fixing the position of a spring. The circulating conveying mechanism is at least partially located above and / or below the output end of the clamping conveying mechanism. The circulating conveying mechanism is used to fix and drive the spring located in the bag to leave the output end of the clamping conveying mechanism and reach a designated position.

[0010] The welding mechanism includes a welding knife and a die, which are arranged opposite to each other. The welding knife and the die can move closer to each other or further away from each other to cooperate in sealing the cloth bag. The welding mechanism can move synchronously or in the opposite direction to the suction cup.

[0011] Furthermore, it also includes an unwinding mechanism for unwinding a roll of fabric to form a bag that at least partially encloses the clamping and conveying mechanism.

[0012] Furthermore, it also includes an output mechanism, which is located at the output end of the welding mechanism and is used to transport the finished product after welding by the welding mechanism.

[0013] Furthermore, it also includes a limiting block, which is used to assist in fixing the spring and suction cup inside the bag.

[0014] Furthermore, the limiting block can be moved synchronously with the welding knife or the die.

[0015] Furthermore, the clamping and conveying mechanism is a clamping conveyor belt / clamping conveyor chain.

[0016] Furthermore, the circulating drive mechanism is an annular conveyor belt / annular conveyor chain, with two annular conveyor belts / annular conveyor chains arranged opposite to each other, and the suction cup is installed between the two annular conveyor belts / annular conveyor chains.

[0017] Furthermore, the distance between the circulating conveying mechanism and the clamping conveying mechanism is adjustable.

[0018] This utility model has the following beneficial effects:

[0019] This utility model discloses a bag-mounted spring welding mechanism. By using suction cups to fix the position of the spring inside the bag from the outside, it ensures that the spring can be accurately disengaged from the clamping and conveying mechanism, effectively avoiding the problem of spring misalignment due to spring release. Secondly, the welding mechanism and the circulating conveying mechanism are moved synchronously, so that the welding knife and die can keep the spring conveyed during the welding process, without waiting for the welding knife and die to complete the welding action and release the bag before conveying, effectively improving efficiency.

Detailed Implementation

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

[0029] like Figures 1-3 The present invention discloses a bag spring insertion and welding mechanism, comprising a clamping and conveying mechanism 1, a circulating conveying mechanism 2, and a welding mechanism 3;

[0030] The clamping and conveying mechanism 1 is used to keep the spring in a compressed state and feed it into the cloth bag 101;

[0031] The circulating conveying mechanism 2 includes at least one circulating drive mechanism 21 and a suction cup 22. Each of the circulating drive mechanisms 21 is provided with at least one suction cup 22 for fixing the position of the spring. The circulating conveying mechanism 21 is at least partially located above and / or below the output end of the clamping conveying mechanism 1. The circulating conveying mechanism 2 is used to fix and drive the spring located in the cloth bag 101 to leave from the output end of the clamping conveying mechanism 1 and reach the designated position.

[0032] The welding mechanism 3 includes a welding knife 31 and a die 32, which are arranged opposite to each other. The welding knife 31 and the die 32 can move closer to each other or further away from each other to cooperate in sealing the cloth bag 101. The welding mechanism 3 can move synchronously or in the opposite direction to the suction cup 22.

[0033] It should be noted that, in the present invention, "the circulating conveying mechanism 2 is used to fix and drive the spring located in the cloth bag 101 to leave from the output end of the clamping conveying mechanism 1 and reach the designated position", the designated position is specifically the position where the spring leaves the clamping conveying mechanism 1 and reaches the welding mechanism 3 to perform the clamping and welding action.

[0034] In use, springs are fed into the cloth bag 101 one by one via the clamping and conveying mechanism 1. At the output end of the clamping and conveying mechanism 1, the suction cup 22 of the circulating conveying mechanism 2 adsorbs and fixes the springs inside the cloth bag 101. The circulating drive mechanism 21 drives the suction cup 22 to move, thereby moving the springs to a designated position. Then, the welding knife 31 and the die 32 of the welding mechanism 3 close and clamp the cloth bag 101 to weld and form a finished product. During the welding process, the welding knife 31 and the die 32 move synchronously with the suction cup 22 to output the welded finished springs outward. Then, the welding knife 31 and the die 32 complete the welding action and move away from each other to release the cloth bag 101. Finally, the welding knife 31 and the die 32 move in the opposite direction to return to the welding position to weld the next spring.

[0035] It should be noted that, preferably, the circulating conveying mechanism 2 is provided with multiple suction cups 22. The clamping conveying mechanism 1 and the circulating conveying mechanism 2 convey synchronously. The welding knife 31 and the die 32 move relatively close or away from each other between two adjacent suction cups 22. When the welding knife 31 and the die 32 clamp the cloth bag 101 for welding and move synchronously with the suction cup 22 to output the welded finished spring, the next suction cup 22 fixes the next spring and moves synchronously to the position waiting to be welded, and so on.

[0036] The advantages of this utility model are: 1. By setting suction cups to fix the position of the spring inside the cloth bag from the outside, the spring can be accurately released from the clamping and conveying mechanism, effectively avoiding the problem of spring misalignment due to spring release when it is released; 2. The welding knife and die are moved synchronously with the circulating conveying mechanism, so that the welding knife and die can keep the spring conveyed during the welding process, without waiting for the welding knife and die to complete the welding action and release the cloth bag before conveying, effectively improving efficiency.

[0037] Furthermore, it also includes an unwinding mechanism 5, which is used to unwind the fabric roll to form a fabric bag 101 that at least partially wraps around the clamping and conveying mechanism.

[0038] It should be noted that the fabric roll is preferably a non-woven fabric roll, and the fabric bag 101 is preferably a non-woven fabric bag.

[0039] It should be noted that by setting the unwinding mechanism 5, the unwinding of the cloth bag 101 is controllable, which is beneficial for the synchronous transport of the cloth bag 101 and the spring.

[0040] Furthermore, it also includes an output mechanism 4, which is located at the output end of the welding mechanism 3 and is used to transport the finished product after welding by the welding mechanism 3.

[0041] It should be noted that by setting the output mechanism 4, the finished product can be transported by the output mechanism 4, thereby providing power and support to the finished product from the outside, effectively ensuring that the finished product can be effectively output after it is detached from the suction cup 22.

[0042] Furthermore, it also includes a limiting block 33, which is used to assist in fixing the spring and suction cup 22 inside the bag 101.

[0043] More specifically, by setting the limiting block 33, the spring can be tightly attached to the suction cup 22 through the cloth bag 101, thereby ensuring that the suction cup 22 can fix the spring inside the cloth bag 101.

[0044] Furthermore, the limiting block 101 can be moved synchronously with the welding knife 31 or the die 32.

[0045] More specifically, in one embodiment of this utility model, the limiting block 101 can move synchronously with the welding knife 31 or the die 32, so that each time the welding knife 31 and the die 32 clamp the cloth bag 101 for welding, the limiting block 101 will press the spring tightly against the suction cup 22 through the cloth bag 101, thereby effectively ensuring that the spring is fixed at the suction cup 22.

[0046] Furthermore, the clamping and conveying mechanism 1 is a clamping conveyor belt / clamping conveyor chain.

[0047] More specifically, clamping conveyor belts / clamping conveyor chains have the advantage of stable conveying and facilitate the compression and conveying of springs.

[0048] Furthermore, the circulating drive mechanism 21 is an annular conveyor belt / annular conveyor chain, with two annular conveyor belts / annular conveyor chains arranged opposite to each other, and the suction cup 22 is installed between the two annular conveyor belts / annular conveyor chains.

[0049] More specifically, the two annular conveyor belts / annular conveyor chains are arranged opposite each other, which helps to avoid the welding knife 31 and the die 32, and facilitates the opening and closing of the welding knife 31 and the die 32.

[0050] Furthermore, the distance between the circulating conveying mechanism 2 and the clamping conveying mechanism 1 is adjustable.

[0051] More specifically, the distance between the circulating conveying mechanism 2 and the clamping conveying mechanism 1 is adjustable, so that the circulating conveying mechanism 2 can cooperate with the clamping conveying mechanism 1 to convey springs of different diameters.

[0052] To further illustrate the advantages of this utility model, such as Figures 4-8 The following is a detailed usage process of this utility model.

[0053] according to Figures 4-8 It can be seen that the process of using this utility model is as follows:

[0054] S1: After the suction cup 22 of the annular conveyor mechanism 2 adsorbs the spring on the outside of the cloth bag 101, it outputs the spring to compress the conveyor mechanism 1 and passes through the welding mechanism 3, waiting for welding (e.g. Figure 4 (as shown);

[0055] S2: The welding knife 31 and the die 32 close and clamp the cloth bag 101 for welding (e.g., ...). Figure 5 (as shown);

[0056] S3: When the welding knife 31 and the die 32 clamp the cloth bag 101 for welding, the annular conveying mechanism 2 and the welding mechanism 3 move synchronously. At this time, the next suction cup 22 will pull the spring in the cloth bag 101 out to compress the conveying mechanism 1 and synchronously transport it to the designated position to wait for welding.

[0057] S4: Open the welding knife 31 and the die 32, and loosen the cloth bag 101;

[0058] S5: Welding knife 31 and die 32 reverse displacement reset, ready for welding.

[0059] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
