The first conveying mechanism is used for circularly conveying springs one by one; the middle compression mechanism is arranged above or below the first conveying mechanism and used for being matched with the first conveying mechanism to compress the spring from the middle of the spring, and at the moment, the two ends of the spring are in an unpressed state; the second conveying mechanism is used for conveying the springs in a compressed state; the middle compression mechanism comprises at least two limiting parts which are oppositely arranged, the limiting parts form a compression section, and the distance between the limiting parts in the compression section is gradually reduced. The middle compression mechanism is arranged, so that the middle part of the spring is directly stressed and compressed in the compression process of the spring, and the two ends of the spring are in a non-pressed state; therefore, the phenomenon that the end position of the spring loses elasticity due to overlarge pressure in the compression process is effectively avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of spring sofas, in particular to a novel spring compression and conveying mechanism. Background Art

[0002] Spring mattress is a common piece of furniture, which is made of several pocket spring strips glued together.

[0003] The production of bagged spring strips requires compressing the springs before placing them in bags for welding, which requires a compression conveying device.

[0004] When existing compression and conveying devices compress and convey the spring at the same time, they often compress from both ends of the spring. However, in fact, the pitch of the spring at both ends is much smaller than the pitch of the middle part of the spring. When the pressure starts, if the compression is directly applied from both ends of the spring, the two ends are often compressed first and then the force is gradually transmitted to the middle part of the spring for compression. This will cause the parts with smaller pitches at both ends of the spring to be constantly under pressure and the force gradually increases, but the middle part cannot get enough pressure for compression, which can easily cause the two ends of the spring to lose elasticity, reduce the overall elastic force of the spring, and be detrimental to the quality of the spring. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a novel spring compression and delivery mechanism which directly compresses the spring from the middle during the compression process.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A novel spring compression conveying mechanism comprises a first conveying mechanism, a middle compression mechanism and a second conveying mechanism;

[0008] a first conveying mechanism for conveying springs cyclically;

[0010] a second conveying mechanism, provided at the output end of the middle compression mechanism, for conveying the spring in a compressed state, and the second conveying mechanism is at least partially located above or below the first conveying mechanism;

[0011] The middle compression mechanism includes at least two relatively arranged limit members, which at least constitute a compression section. Along the conveying direction of the first conveying mechanism, the distance between the limit members gradually decreases within the compression section, and the conveying spring of the first conveying mechanism 1 passes through the middle compression mechanism and enters the second conveying mechanism.

[0012] Furthermore, the first conveying mechanism includes a first conveying belt or a first conveying chain and a suction cup, and at least one suction cup is provided on the first conveying belt or the first conveying chain.

[0013] Furthermore, the middle compressor comprises a parallel section and a compression section, and within the parallel section, the two oppositely arranged limiting members are parallel to each other.

[0014] Furthermore, the middle compression mechanism includes three limiting members, two of which are arranged opposite to each other, and another limiting member is arranged between the two oppositely arranged limiting members.

[0015] Furthermore, the distance between the two oppositely arranged limiting members is adjustable.

[0016] Furthermore, the distance between the first conveying mechanism and the middle compression mechanism is adjustable.

[0017] Furthermore, the second conveying mechanism includes two second conveying belts or second conveying chains that are arranged opposite to each other, and the two second conveying belts or second conveying chains are arranged opposite to each other to clamp and convey the spring.

[0018] Furthermore, the distance between the two second conveyor belts or second conveyor chains is adjustable.

[0019] The utility model has the following beneficial effects:

[0020] The utility model provides a middle compression mechanism so that the middle part of the spring is directly compressed during the compression process, and the two ends of the spring are in a non-compressed state, thereby effectively avoiding the loss of elasticity of the end positions of the spring due to excessive pressure during the compression process; secondly, a second conveying mechanism is provided which is at least partially covered by the first conveying mechanism, so that the first conveying mechanism can stably input the spring from the middle compression mechanism to the second conveying mechanism.

[0024] 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.

[0025] like Figures 1 to 3 The utility model is a novel spring compression conveying mechanism, comprising a first conveying mechanism 1, a middle compression mechanism 2 and a second conveying mechanism 3;

[0026] A first conveying mechanism 1, for conveying springs cyclically;

[0027] The middle compression mechanism 2 is provided above or below the first conveying mechanism 1 and is used to cooperate with the first conveying mechanism 1 to compress the spring from the middle of the spring, while both ends of the spring are in a non-compressed state;

[0028] The second conveying mechanism 3 is provided at the output end of the middle compression mechanism 2 and is used to convey the spring in a compressed state, and the second conveying mechanism 3 is at least partially located above or below the first conveying mechanism 1;

[0029] The middle compression mechanism 2 includes at least two relatively arranged limit members 21, and the limit members 21 at least constitute a compression section 201. Along the conveying direction of the first conveying mechanism 1, the distance between the limit members 21 in the compression section 201 gradually decreases, and the conveying spring of the first conveying mechanism 1 passes through the middle compression mechanism and enters the second conveying mechanism 3.

[0030] When the present invention is in use: the spring is conveyed by the first conveying mechanism 1. When the spring passes through the middle compression mechanism 2, the middle part of the spring is limited by the middle compression mechanism 2 and is gradually compressed during the conveying process. At this time, both ends of the spring are in a non-compressed state. The first conveying mechanism 1 continues to convey the spring so that the spring passes through the middle compression mechanism 2 and is fully compressed before entering the second conveying mechanism 3. The second conveying mechanism 3 keeps the spring in a compressed state for conveying, and in the process of the second conveying mechanism 3 and the first conveying mechanism 1 synchronously conveying the spring, the spring gradually separates from the first conveying mechanism 1.

[0031] The advantages of the present invention are as follows: by providing a middle compression mechanism, the middle part of the spring is directly compressed during the compression process, and the two ends of the spring are in a non-compressed state, thereby effectively avoiding the loss of elasticity of the end positions of the spring due to excessive pressure during the compression process; secondly, a second conveying mechanism is provided that is at least partially covered by the first conveying mechanism, so that the first conveying mechanism can stably input the spring from the middle compression mechanism to the second conveying mechanism.

[0032] Furthermore, the first conveying mechanism 1 includes a first conveying belt or a first conveying chain 11 and a suction cup 12 , and at least one suction cup 12 is provided on the first conveying belt or the first conveying chain 11 .

[0033] More specifically, by providing the suction cup 12 , the spring is fixed by adsorption via the suction cup 12 , thereby ensuring that the spring does not separate from the first conveying mechanism 1 when passing through the middle compression mechanism 2 , thereby ensuring stable conveying by the first conveying mechanism 1 .

[0034] like Figures 1-2 The figure shows one embodiment of the present invention. In this embodiment, the middle compression mechanism 2 is divided into a parallel section 202 and a compression section 201. In the parallel section 202, the two oppositely arranged limiting members 21 are parallel to each other.

[0035] More specifically, by providing the parallel section 202 , the two ends of the spring remain parallel when passing through the middle compression mechanism 2 and entering the second conveying mechanism 3 , thereby facilitating the spring to remain in a compressed state and to escape from the middle compression mechanism 2 and enter the second conveying mechanism 3 .

[0036] Furthermore, the parallel section 202 at least partially extends into the second conveying mechanism 2 .

[0037] More specifically, part of the parallel section 202 extends into the second conveying mechanism 2, so that the spring can enter the second conveying mechanism 3 with both ends kept parallel when passing through the parallel section 202 of the middle conveying mechanism 2, further ensuring that the spring can be smoothly input into the second conveying mechanism 3.

[0038] Furthermore, the middle compression mechanism 2 includes three limiting members 21 , wherein two of the limiting members 21 are arranged opposite to each other, and another limiting member 21 is arranged between the two oppositely arranged limiting members 21 .

[0039] More specifically, by arranging another limiting member 21 between the two limiting members 21 , the spring can be further compressed and limited, and the spring can be effectively prevented from rebounding during transportation.

[0040] Furthermore, the distance between the two oppositely arranged limiting members 21 is adjustable.

[0041] More specifically, the distance between the two limiting members 21 is adjustable so that the compression amount of the spring can be adjusted, which is beneficial for producing products of different sizes.

[0042] Furthermore, the distance between the first conveying mechanism 1 and the middle compression mechanism 2 is adjustable.

[0043] More specifically, the distance between the first conveying mechanism 1 and the middle compression mechanism 2 is adjustable so that the first conveying mechanism 1 and the middle compression mechanism 2 can cooperate to compress and convey springs of different diameters.

[0044] Furthermore, the second conveying mechanism 3 includes two second conveying belts or second conveying chains 31 that are arranged opposite to each other, and the two second conveying belts or second conveying chains 31 are arranged opposite to each other to clamp and convey the spring.

[0045] More specifically, the two second conveyor belts or second conveyor chains 31 are arranged opposite to each other to clamp and convey the spring, so that the spring can be kept in a compressed state for conveyance.

[0046] Furthermore, the distance between the two second conveyor belts or second conveyor chains 31 is adjustable.

[0047] More specifically, the distance between the two second conveyor belts or second conveyor chains 31 is adjustable so that the second conveying mechanism 3 can convey compression springs of different lengths.

[0048] 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.
