Description

Technical Field

[0001] The invention relates to the technical field of bagged spring production machinery, and in particular to a spring compression and 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 ring-shaped conveyor belts / ring-shaped conveyor chains arranged opposite to each other. The two ring-shaped conveyor belts / ring-shaped conveyor chains relatively constitute a compression section and a flat conveying section. The spring is input from the input end of the compression section, and both ends of the spring are tightly attached to the conveyor belt / conveyor chain. At this time, the spring is compressed and conveyed along with the conveyor belt / conveyor chain.

[0004] However, this method has a problem: the two ends of the spring are only fixed by the friction with the conveyor belt / conveyor chain. When the compression amount is large (i.e. high compression), the two sides of the spring move with the conveyor belt / conveyor 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 for conveying, which is not conducive to subsequent bagging and forming.

[0005] In order to solve this problem, there is a spring conveying mechanism with circulating push rods arranged above and below the clamping conveyor belt / clamping conveyor chain. However, this structure is relatively complex and costly, which is not conducive to large-scale production. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention aims to provide a spring compression conveying mechanism which avoids spring rebound and reduces costs.

[0007] To achieve the above object, the present invention adopts the following technical solution:

[0011] The telescopic plate has one end mounted on the chain / flexible belt on one side of the path plate, and the other end mounted on the chain / flexible belt on the other side of the path plate. The telescopic plate telescopes with the cyclic movement of the chain / flexible belt.

The compression parts of the two path plates are relatively formed into a compression section, and the horizontal conveying parts of the two path plates are relatively arranged to form a horizontal conveying section. The path plates are provided with grooves, and the chain / flexible belt is installed on the grooves.

[0014] Furthermore, a bottom baffle is provided at the path plate.

[0015] Furthermore, a protrusion is provided on the inner side of the path plate.

[0016] Furthermore, the distance between the two path plates arranged opposite to each other is adjustable.

[0019] Furthermore, it also includes an annular conveying mechanism and a non-woven bag, wherein the annular conveying mechanism is arranged above the path plate group, and the annular conveying mechanism is used to input the springs one by one between the two path plates. The non-woven bag is arranged at the output end of the two path plates, and the non-woven bag at least partially wraps the path plate group, the telescopic plate and the chain / flexible belt, so that the telescopic plate pushes the spring to move in the non-woven bag.

[0020] Furthermore, the annular conveying mechanism is provided with at least one magnetic suction cup which circulates along with the annular conveying mechanism.

[0021] The present invention has the following beneficial effects:

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to facilitate a clearer understanding of the technical ideas claimed for protection in the present invention.

[0033] like Figures 1 to 9 The spring compression conveying mechanism of the present invention includes a path plate set 1, a chain / flexible belt 2 and a telescopic plate 3;

[0034] The path plate set 1 is composed of at least two path plates 11 arranged opposite to each other. The inner side surfaces of the path plates 11 are arranged opposite to each other to form a compression section 12 and a flat conveying section 13 for limiting the two ends of the spring. The path plate 11 is provided with a guide structure 14 parallel to the inner side surface on a surface perpendicular to the inner side surface. Along the path direction of the path plate set 1, the distance between the inner side surfaces of the two path plates 11 in the compression section 12 gradually decreases;

[0035] Chain / flexible belt 2, at least two chains / flexible belts 2 are respectively wound on the guide structures 14 of the two path plates 11, and the chains / flexible belts 2 make a cyclic motion along the guide structures 14 of the path plates 11;

[0036] The telescopic plate 3 has one end mounted on the chain / flexible belt 2 on the path plate 11 on one side, and the other end mounted on the chain / flexible belt 2 on the path plate 11 on the other side. The telescopic plate 3 telescopes with the cyclic motion of the chain / flexible belt 2.

[0037] It should be noted that the guide structure 14 can be a groove, a chain guide track, a guide pipe, etc. provided on the path plate 11 for guiding, and it only needs to satisfy the chain guide limit.

[0038] When the present invention is in use: the spring is input between the two telescopic plates 3 via the input end of the compression section 12. At this time, the movement of the chain / flexible belt 2 drives the telescopic plate 3 to move, and the telescopic plate 3 pushes the spring to move along the path plate. The two ends of the spring fit with the two inner sides of the path plate 1 so that the spring is gradually compressed when moving along the compression section 12. At the same time, the telescopic plate contracts with the movement, and the telescopic plate 3 pushes the spring into the horizontal conveying section and finally outputs it from the horizontal conveying section.

[0039] The advantages of the present invention are: 1. By setting a path plate and a telescopic plate, the spring is pushed by the telescopic plate, which effectively prevents the spring from rebounding during the conveying process, and no other structures need to be added, which effectively reduces the cost; 2. By setting the telescopic plate, the telescopic plate can be extended and retracted along with the compression and conveying of the spring during the compression and conveying process, thereby ensuring that the telescopic plate remains horizontal in the compression section to push the spring.

[0040] Furthermore, one side of the path plate group 1 is composed of two or more path plates 11 of equal or unequal lengths, wherein one path plate 11 is arranged at an angle, and the other path plate 11 is arranged horizontally, the two inclined path plates 11 are arranged relative to each other to form a compression section 12, and the two horizontally arranged path plates 11 are arranged relative to each other to form a flat conveying section 13, and each of the path plates 11 is provided with a guide structure 14 for winding the chain / flexible belt 2.

[0041] like Figures 6 to 9As shown is one of the embodiments of the present invention. In this embodiment, the path plate group 1 is composed of four path plates, two of which are arranged in parallel and opposite to each other to form a horizontal conveying section 13, and the other two path plates 11 are arranged obliquely and oppositely to each other to form a compression section 12.

[0042] By providing two path plates 11, the chain / flexible belt 2 does not need to make a corner, thereby avoiding the situation where the chain / flexible belt is bent at the corner and thus damaged.

[0043] Furthermore, the path plate group 1 is composed of two oppositely arranged path plates 11, and the path plate 11 is composed of a compression part and a horizontal conveying part. The compression parts of the two path plates 11 are oppositely formed to form a compression section 12, and the horizontal conveying parts of the two path plates 11 are oppositely arranged to form a horizontal conveying section 13. A groove 14 is provided on the path plate 11, and the chain / flexible belt 2 is installed on the groove 14.

[0044] like Figures 1 to 5 As shown, it is one of the embodiments of the present invention. In this embodiment, the path plate group 1 is composed of two path plates 11. The path plate 11 is provided with a bend so that the path plate forms a compression part and a horizontal feeding part. At this time, the groove 14 is also provided with a bend so that the chain / flexible belt 2 can be parallel to the inner side surface of the compression part and the horizontal feeding part of the path plate 11 along the groove 14.

[0045] More specifically, by providing the path plate 11 composed of a compression part and a horizontal conveying part, the structure of the present invention is simplified and the cost is further reduced.

[0046] Furthermore, a bottom baffle 15 is provided at the path plate 11 .

[0047] More specifically, by providing the bottom baffle plate 15 , the spring is effectively prevented from contacting the telescopic plate 3 at the bottom.

[0048] Furthermore, a protrusion 16 is provided on the inner side of the path plate 11 .

[0049] More specifically, by providing the protrusion 16 , the contact area between the spring and the inner side of the path plate 11 can be effectively reduced, thereby reducing the friction between the spring and the path plate 11 .

[0050] Furthermore, the distance between the two path plates 11 arranged opposite to each other is adjustable.

[0051] More specifically, the distance between the two path plates 11 is adjustable, so that the path plate set 1 can be adapted to springs of different sizes, which is convenient for production.

[0052] Furthermore, the telescopic plate 3 includes a sleeve portion 31 and a matching portion 32, the sleeve portion 31 is slidably connected to the matching portion 32, the sleeve portion 31 is installed on one of the chains / flexible belts 2, and the matching portion 32 is installed on the other chain / flexible belt 2, and the telescopic plate 2 is telescoped as the inner side surface spacing of the path plate 11 changes.

[0053] More specifically, by providing the sleeve-fitting portion 31 and the matching portion 32 , in the compression section 12 , the telescopic plate 3 is limited by the sliding connection between the sleeve-fitting portion 31 and the matching portion 32 to maintain horizontality.

[0054] Furthermore, the chain 2 is provided with a mounting structure 21 which can rotate at least at an arbitrary angle, and both ends of the telescopic plate 3 are respectively mounted on the mounting structures 21 of the two chains.

[0055] More specifically, by providing the mounting structure 21 , both ends of the telescopic plate 3 can rotate, thereby preventing the compression section 12 from getting stuck.

[0056] like Figures 1 to 9 The figure shows one embodiment of the mounting structure 21 of the present invention, wherein the mounting structure 21 comprises a mounting plate 22 and a hinged joint 23, wherein the mounting plate 22 is fixed on the chain / flexible belt 2, the hinged joint 23 is hinged on the mounting plate 22, and both ends of the telescopic plate 3 are mounted on the hinged joint 3.

[0057] Furthermore, it also includes a ring conveying mechanism 4 and a non-woven bag 5. The ring conveying mechanism 4 is arranged above the path plate group 1. The ring conveying mechanism 4 is used to input the springs one by one between the two path plates 11. The non-woven bag 5 is arranged at the output end of the two path plates 11, and the non-woven bag 5 at least partially wraps the path plate group 1, the telescopic plate 3 and the chain / flexible belt 2, so that the telescopic plate 3 pushes the spring to move in the non-woven bag 5.

[0058] It should be noted that the horizontal conveying section of the path plate assembly 1 is at least partially located below the annular conveying mechanism 4 .

[0059] More specifically, the annular conveying mechanism 4 is used to input the springs one by one onto the inner side of the path plate 11. At the compression section 12, the spring is conveyed by the chain / flexible belt 2 and the annular conveying mechanism 4, so that the spring is compressed while being conveyed at the compression section 12; when the spring enters the horizontal conveying section 13, the annular conveying mechanism 4 gradually separates from the spring, and at the same time the chain / flexible belt 2 keeps pushing the spring, thereby effectively avoiding the spring from rebounding during the horizontal conveying section; when the spring enters the non-woven bag 5, the chain / flexible belt 2 gradually outputs the spring until the spring leaves the path plate 11 and completely enters the non-woven bag 5.

[0060] Furthermore, the annular conveying mechanism 4 is provided with at least one magnetic suction cup 42 which is circulated along with the annular conveying mechanism 5 .

[0061] It should be noted that the annular conveying mechanism 4 is an annular conveying belt / annular conveying chain 41 , and the magnetic suction cup 42 is installed on the conveying belt / conveying chain 41 of the annular conveying belt / annular conveying chain.

[0062] More specifically, by providing the magnetic suction cup 42, it is ensured that the spring can be adsorbed on the magnetic suction cup 42, thereby ensuring stable spring transportation.

[0063] Furthermore, a support plate 51 is provided at the output end of the path plate group 1 , and the non-woven bag 5 is supported and formed by the support plate 51 .

[0064] More specifically, the support plate 51 is provided to enable the non-woven bag 5 to be supported and formed, and avoid contact with the chain / flexible belt 2 and / or the telescopic plate, thereby preventing the non-woven bag 5 from being damaged when in contact.

[0065] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the present invention.
