Description

Technical Field

[0001] This utility model relates to the field of bag spring production machinery technology, specifically to a bag spring production device. 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 equipment for bagged springs requires a spring-beating head, a receiving conveyor mechanism, a compression conveyor mechanism, and a bag-feeding welding mechanism. Existing bag-feeding welding mechanisms typically include a clamping conveyor belt and a welding mechanism. The clamping conveyor belt feeds the bagged 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 mechanism, the spring is not easily detached from it.

[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 fixed-position, opening and closing welding mechanism is installed. 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 drawbacks: 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, potentially affecting the welding mechanism; 2. Both require additional conveying mechanisms, necessitating more external drives, increasing machine costs, and hindering large-scale production. Utility Model Content

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

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

[0007] A bag spring production apparatus includes a spring striking head, a circulating conveying mechanism, a compression conveying mechanism, and a welding mechanism;

[0008] The spring-beating machine head, located on one side of the circulating conveyor mechanism, is used to produce springs;

[0009] A circulating conveying mechanism includes an annular conveying mechanism and a suction cup. The annular conveying mechanism is provided with at least one suction cup, which can receive the springs produced by the spring-beating machine head.

[0010] A compression conveying mechanism is located below / above the circulating conveying mechanism and is used to cooperate with the circulating conveying mechanism to feed the spring into the cloth bag;

[0011] A welding mechanism is provided at the output end of the compression and conveying mechanism. The welding mechanism includes a welding knife and a die. The welding knife and the die 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 welding and sealing the cloth bag.

[0012] The circulating conveying mechanism comprises at least a first conveying section, a first disengagement section, and a second conveying section. The first conveying section is used to receive the springs produced by the spring-beating machine head and convey the springs to the compression conveying mechanism for synchronous compression and conveying. The first disengagement section is used to separate the springs from the circulating conveying mechanism, and the compression conveying mechanism inputs the compressed springs into the cloth bag within the first disengagement section. The second conveying section at least partially overlaps with the output end of the compression conveying mechanism to assist the springs in the cloth bag in disengaging from the compression conveying mechanism. The welding mechanism is located within the second conveying section.

[0013] Furthermore, the welding mechanism can be synchronously displaced or displaced in the opposite direction along the conveying direction of the circulating conveying mechanism.

[0014] Furthermore, it also includes an unwinding mechanism for unwinding a roll of fabric to form a bag that at least partially encloses the compression conveying mechanism.

[0015] 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.

[0016] Furthermore, it also includes a limiting block, which is used to assist in fixing the spring and suction cup inside the bag.

[0017] Furthermore, the limiting block can be moved synchronously with the welding knife or the die.

[0018] Furthermore, the compression conveying mechanism is composed of at least two conveyor belts / chains arranged opposite each other, the two conveyor belts / chains forming a compression section with a gradually narrowing opening and a flat conveying section that maintains spring compression.

[0019] Furthermore, the circulating conveying mechanism is an annular conveyor belt / annular conveyor chain, with two annular conveyor belts / annular conveyor chains arranged opposite each other. The suction cup is installed between the two annular conveyor belts / annular conveyor chains, and the welding knife and the die are located between the two annular conveyor belts / annular conveyor chains.

[0020] Furthermore, it also includes a second welding mechanism, which is located at the first separation section and is used to weld the two ends of the fabric together to form a fabric bag.

[0021] Furthermore, the distance between the circulating conveying mechanism and the compressing conveying mechanism is adjustable.

[0022] This utility model has the following beneficial effects:

[0023] This utility model discloses a bag spring production device. By setting a first release section and a second conveying section in the circulating conveying mechanism, the spring can be inserted into the bag in the first release section, and a suction cup in the second conveying section can fix the spring outside the bag. This ensures that the suction cup adheres to and fixes the spring when it is released from the compression conveying mechanism, effectively preventing misalignment caused by compression release. Secondly, by setting a first conveying section, a first release section, and a second conveying section in the circulating conveying mechanism, a single circulating conveying mechanism can complete the receiving and conveying of the spring and assist the spring in releasing from the compression conveying mechanism, reducing the number of drives and effectively lowering machine costs. Finally, using suction cups to adhere and convey the spring outside the bag effectively avoids the impact of external drives on the welding mechanism during welding. Attached Figure Description

[0026] Figure 3 for Figure 2 Front view of the embodiment. Detailed Implementation

[0027] 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.

[0028] like Figures 1-3 The present invention discloses a bag spring production device, including a spring striking head 1, a circulating conveying mechanism 2, a compression conveying mechanism 3, and a welding mechanism 4;

[0029] Spring-beating head 1 is located on one side of the circulating conveying mechanism 2 and is used to produce springs;

[0030] The circulating conveying mechanism 2 includes an annular conveying mechanism 21 and a suction cup 22. At least one suction cup 22 is provided on the annular conveying mechanism 21, and the suction cup 22 can receive the springs produced by the spring-beating head 1.

[0031] A compression conveying mechanism 3 is located below / above the circulating conveying mechanism 2 and is used to cooperate with the circulating conveying mechanism 2 to input the spring into the cloth bag;

[0032] Welding mechanism 4 is located at the output end of the compression and conveying mechanism 3. Welding mechanism 4 includes welding knife 41 and die 42. Welding knife 41 and die 42 are arranged opposite to each other. Welding knife 41 and die 42 can be relatively close or far apart to cooperate in welding and sealing cloth bag 101.

[0033] The circulating conveying mechanism 2 comprises at least a first conveying section 201, a first disengagement section 202, and a second conveying section 203. The first conveying section 201 is used to receive the springs produced by the spring-beating machine head 1 and convey the springs to the compression conveying mechanism 3 for synchronous compression and conveying. The first disengagement section 202 is used to separate the springs from the circulating conveying mechanism 2, and the compression conveying mechanism 3 inputs the compressed springs into the cloth bag 101 within the first disengagement section 202. The second conveying section 203 is at least partially overlapped with the output end of the compression conveying mechanism 3 to assist the springs in the cloth bag to disengage from the compression conveying mechanism 3. The welding mechanism 4 is located within the second conveying section 203.

[0034] In use, the springs are produced by the spring-beating machine head 1. The suction cup 22 of the circulating conveying mechanism 2 receives the springs one by one and conveys them one by one towards the compression conveying mechanism 3. After entering the compression conveying mechanism 3, the springs are compressed and conveyed by the limiting of the compression conveying mechanism 3. The compression conveying mechanism 3 and the circulating conveying mechanism 2 synchronously convey and compress the springs until the springs separate from the circulating conveying mechanism 2 at the first separation section 202. At the first separation section 202, after the springs separate from the circulating conveying mechanism 2, the compression conveying mechanism 3 continues to compress and convey the springs and sends them into the cloth bag 101. The compression conveying mechanism 3 compresses and conveys the springs in the cloth bag 101 into the second conveying section 203. At the second conveying section 203, the suction cup 22 can adsorb and fix the spring on the outside of the bag 101. At this time, the circulating conveying mechanism 2 and the compression conveying mechanism 3 synchronously convey the spring. Then, the circulating conveying mechanism 2 keeps the spring in the conveying position so that the spring leaves the output end of the compression conveying mechanism 3. At this time, due to the adsorption and fixation of the suction cup 22, the spring is fixed in the position of the bag 101. Then, the circulating conveying mechanism 2 conveys the spring through the welding mechanism 4 to the designated position. Then, the welding knife 41 and the die 42 of the welding mechanism 4 clamp the bag 101 and weld and seal it to form a bag spring. Then, the welding knife 41 and the die 42 open and reset, waiting for the next spring to be conveyed. This process is repeated to generate a bag spring string.

[0035] It should be noted that, preferably, the circulating conveying mechanism 2 is provided with multiple suction cups 22, the compression conveying mechanism 3 and the circulating conveying mechanism 2 convey synchronously, and the welding knife 31 and the die 32 move relatively close or away from each other between two adjacent suction cups 22.

[0036] The advantages of this utility model are as follows: 1. By setting a first release section and a second conveying section in the circulating conveying mechanism, the spring can enter the bag in the first release section, and the suction cup can fix the spring outside the bag in the second conveying section, thereby ensuring that the suction cup is attracted and fixed when the spring is released from the compression conveying mechanism, effectively avoiding the misalignment caused by compression release when the spring is released from the compression conveying mechanism; 2. By setting a first conveying section, a first release section and a second conveying section in the circulating conveying mechanism, a single circulating conveying mechanism can complete the receiving and conveying of the spring and the action of assisting the spring to release from the compression conveying mechanism, reducing the number of drives and effectively reducing machine costs; 3. Using a suction cup to attract and convey the spring outside the bag effectively avoids the influence of external drives on the welding mechanism during welding.

[0037] Furthermore, the welding mechanism 4 can be synchronously displaced or displaced in the opposite direction along the conveying direction of the circulating conveying mechanism 2.

[0038] When the welding knife 41 and the die 42 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. This process is repeated, eliminating the need to wait for the welding mechanism to finish welding and open before conveying the spring each time, which effectively improves efficiency.

[0039] Furthermore, it also includes an unwinding mechanism 6, which is used to unwind the fabric roll to form a cloth bag 101 that at least partially wraps the compression conveying mechanism.

[0040] 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.

[0041] It should be noted that by setting the unwinding mechanism 6, the unwinding of the cloth bag 101 is controllable, which is beneficial for the synchronous transport of the cloth bag 101 and the spring.

[0042] Furthermore, it also includes an output mechanism 5, which is located at the output end of the welding mechanism 4 and is used to transport the finished product after welding by the welding mechanism 4.

[0043] It should be noted that by setting the output mechanism 5, the finished product can be transported by the output mechanism 5, 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.

[0044] Preferably, the output mechanism 5 is a clamping conveyor belt / clamping conveyor chain.

[0045] Furthermore, it also includes a limiting block 43, which is used to assist in fixing the spring and suction cup 22 inside the bag 101.

[0046] More specifically, by setting the limiting block 43, 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.

[0047] Furthermore, the limiting block 101 can be moved synchronously with the welding knife 41 or the die 42.

[0048] More specifically, in one embodiment of this utility model, the limiting block 101 can move synchronously with the welding knife 41 or the die 42, so that each time the welding knife 41 and the die 42 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.

[0049] Furthermore, the compression conveying mechanism 3 is composed of at least two conveyor belts / conveyor chains arranged opposite each other, the two conveyor belts / conveyor chains forming a compression section 31 with a gradually narrowing opening and a flat conveying section 32 that maintains the spring compression state.

[0050] More specifically, by setting up a compression section 31, the spring can be gradually compressed as it passes through the compression section 31, and by setting up a flat conveying section 32, the spring can be kept in a compressed state for conveying.

[0051] Furthermore, the circulating conveying mechanism 21 is an annular conveyor belt / annular conveyor chain, with two annular conveyor belts / annular conveyor chains arranged opposite each other. The suction cup 22 is installed between the two annular conveyor belts / annular conveyor chains, and the welding knife 41 and the die 42 are located between the two annular conveyor belts / annular conveyor chains.

[0052] 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.

[0053] Furthermore, it also includes a second welding mechanism 7, which is located at the first separation section 202 and is used to weld the two ends of the cloth together to form a cloth bag 101.

[0054] It should be noted that the second welding mechanism 7 can weld the two ends of the cloth together to form a cloth bag 101. At this time, the cloth bag 101 at least partially wraps the compression conveying mechanism 3, and the compression conveying mechanism 3 can send the spring into the cloth bag 101 by conveying the spring.

[0055] It should be noted that a support block (not shown in the figure) should generally also be provided to support the cloth bag 101. Its function is to support the cloth bag in the open state and prevent the cloth bag from directly contacting the compression conveying mechanism 3.

[0056] Furthermore, the distance between the circulating conveying mechanism 2 and the compression conveying mechanism 3 is adjustable.

[0057] More specifically, the distance between the circulating conveying mechanism 2 and the compression conveying mechanism 3 is adjustable, so that the circulating conveying mechanism 2 can cooperate with the compression conveying mechanism 3 to convey springs of different diameters.

[0058] 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.
