Description

Technical Field

[0001] The utility model relates to the technical field of bagged spring production machinery, and particularly relates to a spring bagging mechanism. 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, and when the spring disengages from the compression and conveying mechanism, it completely enters the non-woven fabric bag.

[0004] During the bagging process, in order to ensure that the spring can disengage from the compression and conveying mechanism and enter the non-woven fabric bag, an additional power source is generally arranged at the end of the compression and conveying mechanism to disengage the spring from the compression and conveying mechanism and completely enter the non-woven fabric bag.

[0005] However, when producing bagged springs with a high compression ratio, since high compression treatment needs to be performed on the spring during the compression and conveying process, at this time, 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, that is, the release amount of the spring from the high compression state to both ends closely against the non-woven fabric bag is relatively large. Due to the rapid and uncontrollable elastic deformation of the spring, the spring will quickly release and deform at the moment when the high compression spring leaves the compression and conveying mechanism. At this time, it is very easy to generate deviation, resulting in the misalignment of the spring position in the non-woven fabric bag. In severe cases, it may even cause the spring to suddenly impact the compression and conveying mechanism due to the excessive release amount, resulting in damage to the machine or the spring; at the same time, the excessive one-time release amount of the spring in the high compression state is likely to cause the spring to become weaker in elasticity, which is not conducive to the product quality. Summary of the Utility Model

[0006] 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.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] A spring bagging mechanism includes a compression and conveying mechanism, a support mechanism, a grading and opening mechanism, a transfer mechanism, and a welding mechanism.

[0009] The compression and conveying mechanism 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.

[0010] The support mechanism is used to support the non-woven fabric to form a non-woven fabric bag.

[0011] The grading and opening mechanism is arranged at the output end of the compression and conveying mechanism and at least partially located inside the non-woven bag. The grading and opening mechanism is provided with at least one opening limit.

[0012] The transfer mechanism is used to transfer the springs inside the non-woven bag, so that the springs are gradually released through the grading and opening mechanism.

[0013] The welding mechanism is arranged at the output end of the grading and opening mechanism and / or the supporting mechanism, and is used to weld the bagged springs into a shape.

[0014] Along the transfer direction of the transfer mechanism, the opening sizes of two adjacent opening limits increase step by step. When the spring passes through the grading and opening mechanism, it will be gradually released from the compressed state when it is output by the compression and conveying mechanism.

[0015] Furthermore, the grading and opening mechanism at least includes two oppositely arranged limiting plates, and the two oppositely arranged limiting plates form an opening limit.

[0016] Furthermore, the distance between the two oppositely arranged limiting plates is adjustable.

[0017] Furthermore, the grading and opening mechanism includes two oppositely arranged limiting plates. At least one limiting platform is arranged on the limiting plates so that the limiting plates are in a stepped shape. The limiting platforms on the two limiting plates are arranged opposite to each other one by one to form at least one opening limit.

[0018] Furthermore, the supporting mechanism is two oppositely arranged supporting plates.

[0019] Furthermore, the transfer mechanism includes at least two limiting rods that can limit the springs laterally. The limiting rods can be located outside the non-woven bag, and the two limiting rods drive the springs to gradually pass through and leave the grading and opening mechanism from the outside of the non-woven bag.

[0020] Furthermore, the transfer mechanism includes a driving mechanism, and the driving mechanism is used to drive all the limiting rods to push the springs through the grading and opening mechanism.

[0021] Furthermore, the compression and conveying mechanism is two oppositely arranged conveying chains / conveyor belts.

[0022] Furthermore, the welding mechanism can be displaced along the direction parallel to the transfer direction of the transfer mechanism.

[0023] 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.

[0024] The utility model has the following beneficial effects:

[0025] In the spring bagging mechanism of the present utility model, by setting a hierarchical opening mechanism, the compressed spring is gradually released through the hierarchical opening mechanism, effectively reducing the amount of compression when the spring enters the non-woven bag, and avoiding the situation of dislocation when the spring is released due to excessive release amount when entering the non-woven bag. Secondly, a transfer mechanism is set so that the spring can be transferred along the hierarchical opening mechanism in the non-woven bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is a further description of the present utility model in combination with the drawings and specific embodiments, so as to more clearly understand the technical idea claimed by the present utility model.

[0036] As shown Figures 1 to 5 in the figure, a spring bagging mechanism of the present utility model includes a compression and conveying mechanism 1, a support mechanism 2, a grading and opening mechanism 3, a transfer mechanism 4, and a welding mechanism 5.

[0037] The compression and conveying mechanism 1 is used to clamp the spring along the radial direction of the spring at both ends of the spring, compress the spring, and convey the spring.

[0038] The support mechanism 2 is used to support the non-woven fabric to form a non-woven bag 6.

[0039] The grading and opening mechanism 3 is arranged at the output end of the compression and conveying mechanism 1 and at least partially located inside the non-woven bag 6. The grading and opening mechanism 3 is provided with at least one opening limit 31.

[0040] The transfer mechanism 4 is used to transfer the spring inside the non-woven bag 6 so that the spring is gradually released through the grading and opening mechanism 3.

[0041] The welding mechanism 5 is arranged at the output end of the grading and opening mechanism 3 and / or the support mechanism 2, and is used to weld the spring in the bag into a formed shape.

[0042] Along the transfer direction of the transfer mechanism 4, the opening sizes of two adjacent opening limits 31 increase step by step, and the spring will be gradually released from the compressed state when it is output from the compression and conveying mechanism 1 through the grading and opening mechanism 3.

[0043] When the present utility model is specifically used: the compression and conveying mechanism 1 compresses and conveys the spring until the spring is conveyed to the grading and opening mechanism 3, and then the transfer mechanism 4 transfers the spring through the grading and opening mechanism 3. At this time, the compressed spring passes through at least one opening limit 31 and is released at the opening limit 31. Finally, the spring leaves the grading and opening mechanism 3 and the support mechanism 4 and completely enters the designated position of the non-woven bag 6. Then the welding mechanism 5 clamps the non-woven bag 6 and welds the spring and the non-woven bag 6 into a spring in the bag.

[0044] It should be noted that in one embodiment of the present utility model, the non-woven bag 6 completely wraps the grading and opening mechanism 3, and the output end of the compression and conveying mechanism 1 is partially located inside the non-woven bag 6. In this way, it is ensured that when the spring leaves the compression and conveying mechanism 1 and enters the grading and opening mechanism 3, the spring is inside the non-woven bag 6. At this time, the transfer mechanism 4 can transfer the spring inside the non-woven bag 6.

[0045] It should be noted that the non-woven fabric enters from the bottom / top of the support mechanism 2, and both sides of the non-woven fabric are folded and bonded / welded from both sides of the support mechanism to form a bag shape, so as to form the non-woven bag 6. This technology belongs to the prior art, and its specific structure will not be described in detail here.

[0046] The advantages of the present utility model are as follows: 1. By setting a step-by-step opening mechanism, the compressed spring is gradually released through the step-by-step opening mechanism, effectively reducing the amount of compression of the spring when entering the non-woven bag, and avoiding the situation of dislocation when the spring is released due to excessive release amount when entering the non-woven bag; 2. A transfer mechanism is set, so that the spring can be transferred along the step-by-step opening mechanism in the non-woven bag.

[0047] Further, the step-by-step opening mechanism 3 at least includes two oppositely arranged limiting plates 32, and the two oppositely arranged limiting plates 32 form an opening limit 31.

[0048] In one embodiment of the present utility model, in this embodiment, the step-by-step opening mechanism 3 is composed of at least one group of oppositely arranged limiting plates 32, so that the step-by-step opening mechanism 3 can set multiple opening limits 31 by setting multiple groups of limiting plates 32, so that when the spring passes through the step-by-step opening mechanism 3, it will be gradually released through multiple opening limits 31, effectively ensuring that the instantaneous opening amount of the spring when entering the non-woven bag 6 is reduced, and avoiding dislocation when opening due to excessive compression amount of the spring when entering the non-woven bag 6.

[0049] Further, the distance between the two oppositely arranged limiting plates 32 is adjustable.

[0050] In the step-by-step opening mechanism 3 composed of at least one group of limiting plates 32, the adjustable distance between the two oppositely arranged limiting plates 32 makes the opening size of each opening limit 31 adjustable, so that the size of the gradual release of the spring is controllable.

[0051] Further, the step-by-step opening mechanism 3 includes two oppositely arranged limiting plates 32, and at least one limiting platform 33 is arranged on the limiting plate 32 so that the limiting plate 32 is in a stepped shape, and the limiting platforms 33 on the two limiting plates 32 are arranged opposite to each other one by one to form at least one opening limit 31.

[0052] In one embodiment of the present utility model, in this embodiment, by setting two limiting plates 32 and arranging at least one limiting platform 33 on the two limiting plates 32, at least one opening limit 31 is formed on the two limiting plates 32 to gradually release the compressed spring.

[0053] In this embodiment, the distance between the two limiting plates 32 is adjustable, so that the opening size of the opening limit 31 is adjustable.

[0054] Compared with the step-by-step opening mechanism 3 composed of at least one group of limiting plates 32, the step-by-step opening mechanism 3 composed of one group of limiting plates 32 can synchronously adjust the opening sizes of all opening limits 31 at one time, and has the advantage of simple adjustment.

[0055] Compared with the stepwise opening mechanism 3 composed of a group of limiting plates 32 and multiple limiting platforms 33, the stepwise opening mechanism 3 composed of at least one group of limiting plates 32 has the advantage that the opening size of each opening limit 31 can be adjusted individually.

[0056] Furthermore, the supporting mechanism 2 is two support plates 21 arranged oppositely.

[0057] More specifically, the two support plates 21 support the non-woven fabric to form a non-woven bag 6, so as to ensure that the non-woven bag 6 is in an open state, which is beneficial for the spring to enter the non-woven bag 6.

[0058] It should be noted that the distance between the two support plates 21 is adjustable, so that the opening size of the non-woven bag 6 is adjustable.

[0059] Furthermore, the transfer mechanism 4 includes at least two limiting rods 41 that can limit the spring laterally along the spring. The limiting rods 41 can be located outside the non-woven bag 6, and the limiting rods 41 drive the spring to gradually pass through and leave the stepwise opening mechanism 3 from the outside of the non-woven bag 6.

[0060] More specifically, by setting the limiting rods 41 to displace the spring from the outside of the non-woven bag 6, the spring located inside the non-woven bag 6 can be effectively pushed and displaced.

[0061] Specifically, the limiting rods 41 clamp the non-woven bag 6 from the outside of the non-woven bag 6 to form a deformation of the non-woven bag 6 to limit the spring. At this time, the displacement of the limiting rods 41 drives the spring to displace inside the non-woven bag 6.

[0062] Furthermore, the transfer mechanism 4 includes a driving mechanism 42, and the driving mechanism 42 is used to drive all the limiting rods 41 to push the spring through the stepwise opening mechanism 3.

[0063] More specifically, the driving mechanism 4 preferably uses a ring-shaped conveyor belt / ring-shaped conveyor chain, and more than one limiting rod 41 is installed on the ring-shaped conveyor belt / ring-shaped conveyor chain.

[0064] The ring-shaped conveyor belt / ring-shaped conveyor chain has the advantages of being recyclable, having stable and fast conveying, which is beneficial for the limiting rods 41 to continuously push the spring.

[0065] Furthermore, the compression and conveying mechanism 1 includes two groups of conveyor belts / conveyor chains arranged oppositely. Each group of conveyor belts / conveyor chains is composed of at least one conveyor belt / conveyor chain arranged parallel up and down.

[0066] More specifically, the conveyor belt / conveyor chain constitutes a compression section and a conveying section. The spring is compressed at the compression section, and the spring is conveyed in a compressed state at the conveying section.

[0067] Further, the welding mechanism 5 can be displaced along a direction parallel to the transfer direction of the transfer mechanism.

[0068] More specifically, the welding mechanism 5 is used to weld the bagged springs into shape. The welding includes a welding knife and a die that are oppositely arranged, and the welding knife and the die can approach and move away from each other relatively.

[0069] The welding mechanism 5 can be displaced along the transfer direction of the transfer mechanism, so that the welding knife and the die of the welding mechanism 5 can clamp the non-woven bag 6 for welding, and can also pull the bagged spring for displacement, which is beneficial to continuous production.

[0070] Further, a tension spring mechanism 51 is also provided on the welding mechanism 5, and the tension spring mechanism 51 opens and closes and displaces synchronously with the welding mechanism 5.

[0071] It should be noted that as Figure 1 shown in one embodiment of the present invention, the tension spring mechanism 51 is composed of two tension spring plates 52. The two tension spring plates open and close and displace synchronously with the welding knife and the die of the welding mechanism 5 respectively. The tension spring mechanism 51 is used to pull out and separate the spring located at the output end of the grading opening mechanism 3 or the support mechanism 2 from the grading opening mechanism 3 or the support mechanism 2.

[0072] In Figure 1 the embodiment, when the tension spring mechanism 51 approaches relatively, the two tension spring plates 52 clamp the non-woven bag 6 respectively. At this time, the tension spring plates 52 cause the non-woven bag 6 to deform and squeeze the spring to achieve the purpose of fixing the spring in the position of the non-woven bag 6. Then the tension spring plates 52 are displaced along the displacement direction of the displacement mechanism 4, so that the tension spring plates 52 drive the spring located in the non-woven bag 6 to be displaced synchronously and separate from the grading opening mechanism 3 or the support mechanism 2.

[0073] More specifically, by providing the tension spring mechanism 51, the spring can be effectively separated from the grading opening mechanism 3 or the support mechanism 2.

[0074] More preferably, in the specific embodiment of the present invention, the input end of the transfer mechanism 4 partially overlaps with the output end of the compression and conveying mechanism 1, so that the transfer mechanism 4 can cooperate with the compression and conveying mechanism 1 synchronously to transfer the spring into the grading opening mechanism 3.

[0075] It should be noted that, as Figure 4 shown, when the output end of the support mechanism 2 extends beyond the output end of the grading opening mechanism 3, the space formed by the output end of the support mechanism 2 at this time can be regarded as an additional opening limit 31, and the two ends of the spring after opening are closely attached to the two inner sides of the support plate of the support mechanism 2.

[0076] It should be noted that when the output end of the support mechanism 2 extends beyond the output end of the hierarchical opening mechanism 3, the transfer mechanism 4 can be used to transfer the spring output support mechanism 2 (as Figure 2 shown), or a tension spring mechanism 51 can be provided at the welding mechanism 5 (as Figure 1 shown) to separate the spring from the output end of the support mechanism 2.

[0077] To enable people to further understand the specific advantages of the present invention, as Figures 6 to 9 shown is a schematic diagram of the principle of the spring being transferred by the transfer mechanism 4 to the hierarchical opening mechanism 3 for opening after passing through the compression and conveying mechanism 1.

[0078] As Figure 6 shown, the spring is input from the input end of the compression and conveying mechanism 1. As Figure 7 shown, the spring is compressed and conveyed by the compression and conveying mechanism 1 to the output end of the compression and conveying mechanism 1. At this time, part of the transfer mechanism 4 overlaps so that the transfer mechanism 4 cooperates with the compression and conveying mechanism 1 to convey the spring. As Figure 8 shown, the transfer mechanism 4 cooperates with the compression and conveying mechanism 1 to separate the spring from the compression and conveying mechanism 1. At this time, the spring completely enters the hierarchical opening mechanism 3. As Figure 9 shown, the transfer mechanism 4 drives the spring to displace in the hierarchical opening mechanism 3 in the non-woven bag 6, so that the spring is hierarchically opened by the hierarchical opening mechanism 3.

[0079] In summary, the present invention specifically is: the spring is compressed and conveyed by the compression and conveying mechanism 1 to the output end. At this time, the spring has entered the non-woven bag 6. At this time, the compression and conveying mechanism 1 alone or in cooperation with the transfer mechanism 4 separates the spring from the compression and conveying mechanism 1 and enters the hierarchical opening mechanism 3. Then, the transfer mechanism 4 transfers the spring in the non-woven bag 6 along the hierarchical opening mechanism 3 so that the spring is gradually released. When the spring is transferred to the output end of the hierarchical opening mechanism 3 and / or the support mechanism 2, the transfer mechanism 3 or the tension spring mechanism 51 on the welding mechanism 5 separates the spring from the output end of the hierarchical opening mechanism 3 or the support mechanism 2. At this time, the spring detaches from the hierarchical opening mechanism 3 or the support mechanism 2 and enters the non-woven bag 6. Then, the welding mechanism 5 welds the non-woven fabric to form a bagged spring.

[0080] For those skilled in the art, various corresponding changes and deformations can be made according to the above-described technical solutions and concepts, and all such changes and deformations should fall within the protection scope of the claims of the present invention.
