Description

Technical Field

[0001] The utility model relates to the technical field of bagged spring production machinery, in particular to a spring bagging structure. Background Art

[0002] When conveying and producing bagged springs, a spring compression and conveying bagging mechanism is required.

[0003] The existing spring compression and conveying bagging mechanism generally involves the cooperation of a compression and conveying mechanism and a non-woven fabric bag support. The compression and conveying mechanism compresses and conveys the spring into a non-woven fabric bag supported by the support. At this time, part of the compression and conveying mechanism is arranged inside the non-woven fabric bag. When the spring detaches from the compression and conveying mechanism, it completely enters the non-woven fabric bag.

[0004] However, when producing bagged springs with a high compression ratio, since high compression treatment of the spring is required during the compression and conveying process, the distance between the outlet size of the compression and conveying mechanism and the opening size of the non-woven fabric bag is relatively large at this time. After the spring is output at the end of the compression and conveying mechanism, the spring will be directly released. At this time, the spring will rub against the end of the compression and conveying mechanism, and since the spring opens freely, it is very easy to be misaligned. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model aims to provide a spring bagging mechanism that can release high-compression springs in stages.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A spring bagging structure includes a compression and conveying mechanism, a support mechanism, and a welding mechanism;

[0008] The compression and conveying mechanism is used to clamp the spring along the radial direction of the spring from both ends, compress the spring, and convey the spring;

[0009] The support mechanism is arranged on both sides of the compression and conveying mechanism to support the non-woven fabric to form a non-woven fabric bag;

[0010] The welding mechanism is arranged at the output end of the compression and conveying mechanism and / or the support mechanism to weld the bagged spring into shape;

[0011] An opening section is arranged at the output end of the compression and conveying mechanism. The conveying direction of the opening section is parallel to the clamping and compression direction of the compression and conveying mechanism. The opening section is arranged between the compression and conveying mechanism and the support mechanism to assist the spring to be released and opened in the non-woven fabric bag.

[0012] Further, the compression and conveying mechanism includes two groups of oppositely arranged conveyor belts / conveyor chains. Each group of conveyor belts / conveyor chains consists of at least one conveyor belt / conveyor chain arranged in parallel up and down.

[0013] Furthermore, in each group of the conveyor belts / conveyor chains, at least one conveyor belt / conveyor chain extends outward to form an opening section.

[0014] Furthermore, along the conveying direction of the compression conveying mechanism, the compression conveying mechanism sequentially forms a compression section, a flat conveying section, and an opening section. The compression section is used to compress the spring, and the flat conveying section is used to feed the spring in a compressed state into the non-woven bag.

[0015] Furthermore, the support mechanism includes two oppositely arranged support plates, and the two support plates are respectively arranged on both sides of the compression conveying mechanism. The opening section is arranged between the support plate and the compression conveying mechanism.

[0016] Furthermore, the distance between the two support plates is adjustable.

[0017] Furthermore, the welding mechanism includes a knife die and a welding knife, and the knife die and the welding knife can be opened and closed relative to each other to clamp the non-woven bag for welding.

[0018] Furthermore, the welding mechanism can be displaced along the conveying direction parallel to the compression conveying mechanism.

[0019] Furthermore, a tension spring mechanism is also arranged on the welding mechanism, and the tension spring mechanism opens and closes and displaces synchronously with the welding mechanism.

[0020] Furthermore, the tension spring mechanism includes a mounting plate and a tension spring plate. The two mounting plates are respectively fixedly connected to the knife die and the welding knife, and the two tension spring plates are respectively mounted on one mounting plate, and the positions of the two tension spring plates are opposite.

[0021] The utility model has the following beneficial effects:

[0022] In a spring bagging structure of the utility model, an opening section parallel to the spring compression direction is arranged at the output end of the compression conveying mechanism. At this time, the spring opening direction is the same as the conveying direction of the opening section, which not only effectively reduces the friction between the two, but also provides a directional force to both ends of the spring to keep the spring open in parallel.

[0025] Figure 3This is a schematic front view of one implementation of a spring bagging structure of the present utility model for observing the principle of spring input into a non-woven bag. Specific implementation

[0026] The following combines the accompanying drawings and specific embodiments to further describe the present utility model for a clearer understanding of the technical idea claimed by the present utility model.

[0027] As Figures 1 to 3 shown, a spring bagging structure of the present utility model includes a compression and conveying mechanism 1, a support mechanism 2, and a welding mechanism 3;

[0028] The compression and conveying mechanism 1 is used to clamp the spring along the radial direction of the spring from both ends of the spring, compress the spring, and convey the spring;

[0029] The support mechanism 2 is arranged on both sides of the compression and conveying mechanism 1 to support the non-woven fabric to form a non-woven bag 201;

[0030] The welding mechanism 3 is arranged at the output end of the compression and conveying mechanism 1 and / or the support mechanism 2 to weld the bagged spring into a shape;

[0031] An opening section 13 is provided at the output end of the compression and conveying mechanism 1. The conveying direction of the opening section 13 is parallel to the clamping and compression direction of the compression and conveying mechanism 1. The opening section 13 is arranged between the compression and conveying mechanism 1 and the support mechanism 2 to assist the spring to be released and opened in the non-woven bag 201.

[0032] When the present utility model is in use, the spring is conveyed by the compression and conveying mechanism 1 into the non-woven bag 201 supported by the support mechanism 2. When the spring exits the compression and conveying mechanism 1, the spring is subjected to the force of the opening section 13 at the output end of the compression and conveying mechanism 1. Since the conveying direction of the opening section 13 is parallel to the release and opening direction of the spring, the opening section 13 assists the spring to be released and opened at this time.

[0033] The advantages of the present utility model are as follows: By providing an opening section parallel to the spring compression direction at the output end of the compression and conveying mechanism, the spring opening direction is the same as the conveying direction of the opening section at this time, which not only effectively reduces the friction between the two, but also provides a directional force to both ends of the spring to keep the spring parallel and open.

[0034] Furthermore, the compression and conveying mechanism 1 includes two sets of oppositely arranged conveyor belts / conveyor chains, and each set of conveyor belts / conveyor chains is composed of at least one conveyor belt / conveyor chain arranged in parallel up and down.

[0035] More specifically, the conveyor belt / conveyor chain has the advantages of stable and fast conveying, which is conducive to continuous conveying of the spring.

[0036] Furthermore, in each group of the conveyor belts / conveyor chains, at least one conveyor belt / conveyor chain extends outward to form an opening section 13.

[0037] Furthermore, along the conveying direction of the compression conveying mechanism 1, the compression conveying mechanism 1 successively forms a compression section 11, a horizontal conveying section 12, and an opening section 13. The compression section 11 is used to compress the spring, and the horizontal conveying section 12 is used to keep the spring in a compressed state and feed it into the non-woven bag 201.

[0038] As Figure 1 shown in one embodiment of the present invention, in this embodiment, the compression section 11, the horizontal conveying section 12, and the opening section 13 are formed by winding the conveyor belt / conveyor chain, so that the conveyor belt / conveyor chain runs as a whole, which is beneficial to linkage.

[0039] As Figure 2 shown in another embodiment of the present invention, in this embodiment, the compression section 11, the horizontal conveying section 12, and the opening section 13 are respectively arranged in a staggered manner, so that the installation is simple. When a problem occurs in a part of the conveyor belt / conveyor chain, only the corresponding part needs to be replaced, which is beneficial to maintenance.

[0040] Furthermore, the support mechanism 2 includes two oppositely arranged support plates 21. The two support plates 21 are respectively arranged on both sides of the compression conveying mechanism 1, and the opening section 13 is arranged between the support plate 21 and the compression conveying mechanism 1.

[0041] More specifically, the horizontal conveying section is arranged between the compression conveying mechanism 1 and the support plate 21, which can effectively prevent the spring from getting stuck in the gap between the compression conveying mechanism 1 and the support plate 21 when the spring is released.

[0042] Furthermore, the distance between the two support plates 21 is adjustable.

[0043] More specifically, a tensioning wheel 14 is arranged at the opening section 13, so that the length of the opening section 13 is adjustable. Thus, when the distance between the support plates 21 needs to be adjusted, the length of the opening section 13 can be adjusted simultaneously to make the distance between the opening section 13 and the support plate 21 adaptable.

[0044] Furthermore, the welding mechanism 3 includes a die 31 and a welding knife 32. The die 31 and the welding knife 32 can open and close relatively to clamp the non-woven bag 201 for welding.

[0045] More specifically, the die 31 and the welding knife 32 cooperate to weld the spring and the non-woven bag 201 into a bagged spring.

[0046] Furthermore, the welding mechanism 3 can be displaced along the conveying direction parallel to the compression conveying mechanism 1.

[0047] To further promote, the welding mechanism 3 can be displaced along the conveying direction of the compression conveying mechanism 1, so as to displace the spring and the non-woven fabric during welding to facilitate the output of the next spring from the compression conveying mechanism 1.

[0048] Furthermore, a tension spring mechanism 4 is also provided on the welding mechanism 3, and the tension spring mechanism 4 opens and closes and displaces synchronously with the welding mechanism 3.

[0049] More specifically, by providing the tension spring mechanism 4, it is helpful to output the spring located in the non-woven fabric bag 201 from the compression conveying mechanism 1, which is beneficial to the output and release of the spring.

[0050] Furthermore, the tension spring mechanism 4 includes a mounting plate 41 and a tension spring plate 42. The two mounting plates are respectively fixedly connected to the die cutter and the welding knife. The two tension spring plates are respectively mounted on one mounting plate, and the positions of the two tension spring plates are opposite.

[0051] As Figure 3 shown in one embodiment of the present invention, the two tension spring plates 42 open and close and displace synchronously with the die cutter 31 and the welding knife 32 of the welding mechanism 3. The tension spring mechanism 4 is used to pull out the spring located at the output end of the compression conveying mechanism 1 or the support mechanism 2 from the compression conveying mechanism 1 or the support mechanism 2, so that the spring is completely out of the compression conveying mechanism and / or the support mechanism 2 and into the bag.

[0052] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
