Description

Technical Field

[0001] The utility model relates to the technical field of spring cushion machinery, in particular to a spring conveying mechanism. Background Art

[0002] In the process of bagged spring production, the springs need to be compressed and then fed into non-woven bags. At this time, a spring compression and conveying mechanism is needed.

[0003] The existing spring compression conveying mechanism is generally composed of a clamping conveyor belt / clamping conveyor chain composed of two circular conveyor belts / circular conveyor chains arranged opposite to each other. The two circular conveyor belts / circular conveyor chains form a compression section and a flat conveying section. The spring is input from the input end of the compression section, and the two ends of the spring are tightly attached to the conveyor belt / conveyor chain. At this time, the spring is compressed and conveyed as the conveyor belt / conveyor chain conveys.

[0004] However, this method has a problem: the two ends of the spring are fixed only by the friction with the conveyor belt / chain. When the compression amount is large (i.e. high compression), the spring is conveyed in a compressed state. The two sides of the spring move with the conveyor belt / chain while the middle part is maintained for a moment. During this process, the high compression amount of the spring will cause it to rebound, making it impossible for the spring to maintain its position during conveying, which is not conducive to subsequent bagging and forming.

[0005] In order to solve this problem, circulating push rods driven by chains / belts are respectively set above and below the clamping conveyor belt / clamping conveyor chain to limit the spring through the push rods. However, this structure is relatively complex and costly, which is not conducive to large-scale production. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a spring cushion production device with continuous movements.

[0012] a non-woven bag, provided at the output end of the third conveying mechanism, and wrapping at least a portion of the third conveying mechanism;

[0013] The third conveying mechanism includes a path plate, a chain / flexible belt and a push plate. The inner side surfaces of the two path plates are arranged relative to each other to keep the spring compressed. A guide structure parallel to the inner side surface of the path plate is provided on the surface of the path plate perpendicular to the inner side surface. The chain / flexible belt is wound around the path plate through the guide structure. A push plate is provided on the chain / flexible belt to push the spring when it rotates with the chain / flexible belt.

[0014] Furthermore, the second conveying mechanism includes two second conveying belts / second conveying chains arranged opposite to each other, and along the conveying direction of the second conveying mechanism, the distance between the two second conveying belts / second conveying chains gradually decreases.

[0015] Furthermore, the input end of the third conveying mechanism is at least partially located below the first conveying mechanism.

[0020] Furthermore, a supporting mechanism for supporting the non-woven bag is provided outside the third conveying mechanism.

[0021] Furthermore, the supporting mechanism is a supporting plate provided at the output end of the third conveying mechanism.

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

[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 to be protected by the present invention.

[0029] like Figures 1 to 4 The utility model is a spring conveying mechanism, comprising a first conveying mechanism 1, a second conveying mechanism 2, a third conveying mechanism 3 and a non-woven bag 4;

[0030] A first conveying mechanism 1 includes a first conveyor belt / first conveyor chain 11, on which at least one magnetic suction cup 12 is provided, and the first conveying mechanism 1 is used for cyclically conveying the springs;

[0031] The second conveying mechanism 2 is provided below the first conveying mechanism 1 and is used to compress and convey the spring;

[0032] The third conveying mechanism 3 is provided at the output end of the second conveying mechanism 2 and is used to keep the spring compressed and convey it to the non-woven bag 4;

[0033] a non-woven bag 4, provided at the output end of the third conveying mechanism 3, and wrapping at least a portion of the third conveying mechanism 3;

[0034] The third conveying mechanism 3 includes a path plate 31, a chain / flexible belt 32 and a push plate 33. The inner side surfaces of the two path plates 31 are arranged relative to each other to keep the spring compressed. The path plate 31 is provided with a guide structure 37 parallel to the inner side surface of the path plate 31 on the surface perpendicular to the inner side surface. The chain / flexible belt 32 is wound on the path plate 31 through the guide structure 37. The chain / flexible belt 32 is provided with a push plate 33 that rotates with the chain / flexible belt 32 to push the spring.

[0035] It should be noted that the guide structure 37 can be a groove, a chain guide track, a guide pipe, etc. provided on the path plate 31 for guidance, and it only needs to meet the chain guide limit.

[0036] When the present invention is in use, the spring is circulated and conveyed to the second conveying mechanism 2 via the first conveying mechanism 1, and then the first conveying mechanism 1 and the second conveying mechanism 2 are conveyed synchronously. The spring is gradually compressed in the process of passing through the second conveying mechanism 2, and the first conveying mechanism 1 and / or the second conveying mechanism 2 outputs the compressed spring to between the two path plates 31 of the third conveying mechanism 3. At this time, the inner side surfaces of the two path plates 31 are close to the two sides of the spring to limit the spring, and then the push plate 33 pushes the spring for conveyance, and within the range of the non-woven bag 4 wrapping the third conveying mechanism 3, the push plate 33 remains in the non-woven bag 4 to convey the spring, and the third conveying mechanism 3 continues to push the spring until the spring completely leaves the third conveying mechanism 3 and enters the non-woven bag 4.

[0037] The advantages of the present invention are as follows: 1. A third conveying mechanism consisting of a path plate and a push plate is provided. The path plate is used to clamp the spring to keep the spring in a compressed state, and the push plate is used to push the spring to move under the clamping of the two path plates, thereby both maintaining the conveying spring and pushing the spring through the push plate to prevent the spring from rebounding; 2. By providing a third conveying mechanism that can push the spring inside the non-woven bag, there is no need to add an additional conveying mechanism outside the non-woven bag, which effectively reduces costs; finally, the third conveying mechanism has a compact structure and high space utilization, which is conducive to large-scale production of machines.

[0038] Furthermore, the second conveying mechanism 2 includes two second conveying belts / second conveying chains 21 arranged opposite to each other. Along the conveying direction of the second conveying mechanism 2, the distance between the two second conveying belts / second conveying chains 21 gradually decreases.

[0039] More specifically, a second conveyor belt / second conveyor chain 21 is used to compress and convey the spring. At this time, the second conveyor belt / second conveyor chain 21 runs synchronously with the first conveying mechanism 1 to cooperate in conveying the spring, so that the spring is gradually compressed in the process of passing through the second conveyor belt / second conveyor chain 21.

[0040] Furthermore, the input end of the third conveying mechanism 3 is at least partially located below the first conveying mechanism 1 .

[0041] More specifically, the input end of the third conveying mechanism 3 is at least partially located below the first conveying mechanism 1 so that the first conveying mechanism 1 drives the spring from the output end of the second conveying mechanism 2 into the third conveying mechanism 3, thereby facilitating the spring to separate from the second conveying mechanism 2 and enter the third conveying mechanism.

[0042] Furthermore, the distance between the two path plates 31 is adjustable.

[0043] More specifically, the adjustable spacing of the path plates 31 allows for adjustable spring compression, facilitating the production of products of different sizes.

[0044] Furthermore, a protrusion 36 is provided on the path plate 31 .

[0045] More specifically, by providing the protrusion 36 , the spring is in close contact with the protrusion 36 , which reduces the contact area between the spring and the path plate 31 , thereby reducing friction.

[0046] Furthermore, the push plate 33 includes a sleeve portion 34 and a matching portion 35, the sleeve portion 34 is slidably connected to the matching portion 35, the sleeve portion 34 is installed on one of the chains / flexible belts 2, and the matching portion 35 is installed on the other chain / flexible belt 2.

[0047] More specifically, by providing the matching portion 34 and the sleeve portion 35 , the push plate 33 can be extended and retracted, thereby enabling the push plate 33 to be extended and retracted as the spacing of the path plates 11 is adjusted.

[0048] Furthermore, the third conveying mechanism 3 is provided with a baffle 38 for preventing the spring from contacting the bottom push plate 33 .

[0049] More specifically, by providing the baffle 38 , the spring and the bottom push plate 33 are effectively separated, thereby facilitating continuous production.

[0050] Furthermore, a supporting mechanism 41 for supporting the non-woven bag 4 is provided outside the third conveying mechanism 3 .

[0051] More specifically, the supporting mechanism 41 is provided so that the non-woven bag 4 can maintain the bag opening state.

[0052] Furthermore, the support mechanism 41 is a support plate provided at the output end of the third conveying mechanism 3 .

[0053] More specifically, Figure 1 As shown, the support plate partially wraps the output end of the third conveying mechanism 3 , and the non-woven bag is now separated from the third conveying mechanism 3 by the support plate to prevent the non-woven bag 4 from contacting the third conveying mechanism 3 .

[0054] Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all of these changes and modifications should fall within the scope of protection of the claims of the present utility model.
