Description

Technical Field

[0001] The utility model relates to the technical field of spring mattress production equipment, in particular to a spring conveying device. Background Art

[0002] Spring mattress is a commonly used furniture.

[0003] When conveying springs, a spring conveying device is required, especially a conveying device that conveys the springs in a compressed state.

[0004] Existing compression conveying equipment generally compresses and clamps the spring through a clamping conveyor belt / clamping conveyor chain for conveying. However, in this way, at the end of the clamping conveyor belt / clamping conveyor chain, the spring cannot be completely output from the clamping conveyor belt / clamping conveyor chain due to the rotation angle position of the sprocket. At this time, a tension spring mechanism is required to pull the spring out of the clamping conveyor belt / clamping conveyor chain.

[0005] However, when a tension spring mechanism is set to pull the spring out from the outlet end of the clamping conveyor belt / clamping conveyor chain, since the spring is in a compressed state, the friction between the two ends of the spring and the conveyor belt / conveyor chain is relatively large. Therefore, when the tension spring mechanism pulls the spring out of the conveyor belt / conveyor chain, the spring tends to generate greater friction with the conveyor belt / conveyor chain. At this time, the spring causes greater loss to the conveyor belt / conveyor chain, which will greatly reduce the service life of the conveyor belt / conveyor chain. Summary of the invention

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a spring compression conveying mechanism which can prevent the spring from contacting the conveyor belt / conveying chain when the spring is pulled out.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A spring conveying device comprises a clamping conveying mechanism and a tension spring mechanism;

[0009] A clamping conveying mechanism, comprising a conveying belt / conveying chain and a limiting plate, wherein the two groups of conveying belts / conveying chains are arranged opposite to each other to form a clamping conveying belt / conveying chain, and each group of conveying belts / conveying chains is provided with a limiting plate, and at the output end of the clamping conveying mechanism, the conveying belt / conveying chain or the limiting plate is provided with a covering section, and the conveying surface of the conveying belt / conveying chain at the outlet end in the covering section is completely covered in the limiting plate, so that when the conveying belt / conveying chain conveys the spring to the outlet end of the clamping conveying mechanism, the spring is clamped and fixed by the limiting plate at the outlet end;

[0010] The tension spring mechanism is arranged at the output end of the clamping and conveying mechanism and is used to pull the spring out of the clamping and conveying mechanism from the outlet end of the clamping and conveying mechanism.

[0011] Furthermore, a compression section is provided on the limit plate, and the covering section is the compression section of the limit plate. In the compression section, the interval between the two limit plates along the conveying direction of the clamping conveying mechanism gradually becomes smaller, and in the compression section, the limit plate completely covers the conveying surface of the conveyor belt / conveyor chain.

[0012] Furthermore, the conveyor belt / conveyor chain constitutes a conveying section and a waiting section. In the conveying section, the distance between the conveying surfaces of the two groups of conveyor belts / conveyor chains is less than or equal to the distance between the inner side surfaces of the two limiting plates. The covering section is a waiting section provided on the conveyor belt / conveyor chain. The waiting section is provided at the output end of the clamping conveying mechanism. In the waiting section, the two groups of conveyor belts / conveyor chains are respectively inclined outward along the inner sides of the two limiting plates so that the distance between the two adjacent groups of conveyor belts / conveyor chains gradually increases so that the conveying surface of the conveyor belt / conveyor chain is completely covered within the limiting plates.

[0013] Furthermore, a plurality of blocks are arranged on the conveying surface of the conveyor belt / conveyor chain, and at the outlet end of the clamping conveying mechanism, the blocks are completely covered in the limiting plate.

[0014] Furthermore, the angle between the stopper and the inner side surface of the conveyor belt / conveyor chain along the conveying direction of the clamping conveying mechanism is less than 90°.

[0015] Furthermore, the tension spring includes two clamping plates, and the two clamping plates can be relatively close to or away from each other in a direction perpendicular to the conveying direction of the clamping and conveying mechanism, and the two clamping plates can be displaced back and forth in a direction parallel to the conveying direction of the clamping and conveying mechanism.

[0016] Furthermore, it also includes an adjusting mechanism, which is used to adjust the distance between the two groups of conveyor belts / conveyor chains in the clamping conveying mechanism.

[0017] Furthermore, the adjustment mechanism includes a base frame, a sliding frame and a screw rod. The base frame is fixedly arranged, and the two sliding frames are respectively slidably connected to the base frame. The screw rod is threadedly connected to at least one of the sliding frames. The rotation of the screw rod drives the two sliding frames to be relatively close or relatively far away, and the two groups of conveyor belts / conveyor chains are respectively installed on the two sliding frames.

[0018] Furthermore, the spacing between the limit plates can be adjusted independently of the conveyor belt / conveyor chain.

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

[0020] The utility model discloses a spring conveying device, by arranging a covering section at the outlet end of a clamping conveying mechanism, so that a limit plate completely covers a conveying belt / conveying chain in the covering section, so that the spring is only in contact with the limit plate in the covering section, thereby avoiding friction between the spring and the conveying belt / conveying chain when the tension spring mechanism pulls out the spring, thereby avoiding a reduction in the service life of the conveying belt / conveying chain due to friction.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0027] like Figures 1 to 5 The utility model is a spring conveying device, comprising a clamping conveying mechanism 1 and a tension spring mechanism 2;

[0028] The clamping conveying mechanism 1 comprises a conveying belt / conveying chain 11 and a limiting plate 12. The two groups of conveying belts / conveying chains 11 are arranged relatively to form a clamping conveying belt / clamping conveying chain. The limiting plate 12 is respectively arranged on each group of conveying belts / conveying chains 11. At the output end of the clamping conveying mechanism 1, the conveying belt / conveying chain 11 or the limiting plate 12 is provided with a covering section. In the covering section, the conveying surface of the conveying belt / conveying chain 11 at the outlet end is completely covered in the limiting plate 12, so that when the conveying belt / conveying chain 11 conveys the spring to the outlet end of the clamping conveying mechanism, the spring is clamped and fixed by the limiting plate 12 at the outlet end.

[0029] The tension spring mechanism 2 is arranged at the output end of the clamping and conveying mechanism 1 and is used to pull the spring out of the clamping and conveying mechanism 1 from the outlet end of the clamping and conveying mechanism 1 .

[0030] More specifically, when the utility model is used, the spring is clamped and conveyed by the clamping and conveying mechanism 1. At this time, the spring remains in a compressed state. The clamping and conveying mechanism 1 conveys the spring to the covering section. Since the conveying surface of the conveyor belt / conveyor chain is completely covered in the limit plate 12, the two ends of the spring are only in contact with the limit plate 12 at this time, and then the tension spring mechanism 2 pulls the spring out of the covering section of the clamping and conveying mechanism 1. During the pulling process, the spring does not need to contact the conveyor belt / conveyor chain.

[0031] The advantages of the utility model are as follows: by arranging a covering section at the outlet end of the clamping conveying mechanism, the limit plate completely covers the conveyor belt / conveyor chain in the covering section, so that the spring only contacts the limit plate when in the covering section, avoiding friction between the spring and the conveyor belt / conveyor chain when the tension spring mechanism pulls out the spring, thereby avoiding a reduction in the service life of the conveyor belt / conveyor chain due to friction.

[0032] It should be noted that the structure to be protected by the present invention is: the cooperation of the conveyor belt / conveyor chain 11, the limit plate 12 and the tension spring mechanism 2 at the covering section of the clamping conveying mechanism 1. By setting the covering section, the conveyor belt / conveyor surface 11 conveys the spring to the covering section and then separates from the conveying surface of the conveyor belt / conveyor chain 11, so that when the tension spring mechanism 2 pulls the spring out of the covering section, the spring only contacts with the limit plate 12.

[0033] Furthermore, a compression section 13 is provided on the limit plate 12, and the covering section is the compression section 13 of the limit plate 12. In the compression section 13, the interval between the two limit plates 12 along the conveying direction of the clamping conveying mechanism 1 gradually becomes smaller, and in the compression section 13, the limit plate 12 completely covers the conveying surface of the conveyor belt / conveyor chain 11.

[0034] like Figures 1 to 3 Shown is one implementation of the present utility model.

[0035] In this embodiment, the covering section is a compression section 13 arranged on the limit plate 12. In the compression section 13, along the conveying direction of the clamping and conveying mechanism 1, the spacing of the limit plate 12 gradually becomes smaller, so that the limit plate 12 can cover the conveying surface of the conveyor belt / conveyor chain. After the conveyor belt / conveyor chain 11 completely sends the spring into the compression section 13, the spring is separated from the conveyor belt / conveyor chain 11. At this time, when the tension spring mechanism 2 pulls the spring out of the clamping and conveying mechanism 1 from the compression section 13, the spring only generates friction with the limit plate 12.

[0036] Furthermore, the conveyor belt / conveyor chain 11 constitutes a conveying section 14 and a waiting section 15. In the conveying section 14, the distance between the conveying surfaces of the two groups of conveyor belts / conveyor chains 11 is less than or equal to the distance between the inner side surfaces of the two limiting plates 12. The covering section is the waiting section 15 provided on the conveyor belt / conveyor chain. The waiting section 15 is provided at the output end of the clamping conveying mechanism 1. In the waiting section 15, the two groups of conveyor belts / conveyor chains 11 are respectively inclined outward along the inner sides of the two limiting plates 12 so that the distance between the two adjacent groups of conveyor belts / conveyor chains 11 gradually increases so that the conveying surface of the conveyor belt / conveyor chain 11 is completely covered in the limiting plates 12.

[0037] like Figures 4-5 , which is one implementation mode of the present utility model.

[0038] In this embodiment, the covering section is a waiting section 15 arranged on the conveyor belt / conveyor chain 11. Since in the waiting section 15, the two groups of conveyor belts / conveyor chains 11 are respectively inclined outward along the inner side of the limiting plate 12, so that the two adjacent groups of conveyor belts / conveyor chains 11 are gradually completely covered by the limiting plate 12. At this time, when the two groups of conveyor belts / conveyor chains 11 convey the spring to the waiting section 15, the spring and the conveying surface of the conveyor belt / conveyor chain 11 are gradually completely separated. At this time, the spring only contacts the limiting plate 12, and then the tension spring mechanism 2 pulls the spring from the waiting section 15 out of the clamping conveying mechanism 1. During the pulling process, the spring only contacts the limiting plate 12.

[0039] Furthermore, a plurality of blocks 16 are provided on the conveying surface of the conveyor belt / conveyor chain 11 , and within the covering section at the outlet end of the clamping conveying mechanism 1 , the blocks 16 are completely covered within the limiting plate 12 .

[0040] More specifically, by providing the stopper 16, the conveyor belt / conveyor chain 11 can push the spring through the stopper 16, thereby ensuring that the spring will not slip on the conveyor belt / conveyor chain 11 during the conveying process.

[0041] Furthermore, the angle between the stopper 16 and the inner side surface of the conveyor belt / conveyor chain 11 along the conveying direction of the clamping conveying mechanism 1 is less than 90°.

[0042] More specifically, the angle of the stopper 16 is less than 90°, so that the inner end face of the spring will not detach from the stopper 16 when it is stuck within the angle between the stopper 16 and the conveying surface of the conveyor belt / conveyor chain 11, ensuring the accurate position of the spring of the conveyor belt / conveyor chain 11 during the conveying process.

[0043] Furthermore, the tension spring mechanism 2 includes two clamps 21, and the two clamps 21 can be relatively close to or away from each other in a direction perpendicular to the conveying direction of the clamping and conveying mechanism 1, and the two clamps 21 can move back and forth in a direction parallel to the conveying direction of the clamping and conveying mechanism 1.

[0044] More specifically, by providing the clamping plate 21 , the tension spring mechanism 2 can clamp and release the spring by opening and closing the clamping plate 21 , thereby achieving the action of the tension spring mechanism 2 pulling the spring out of the covering section.

[0045] It should be noted that, in one embodiment, the width of the clamping plate 21 is less than or equal to the minimum distance between the two limiting plates 12 in the covering section, and the clamping plate 21 extends into the clamping and conveying mechanism 1 to pull out the spring.

[0046] It should be noted that, in one embodiment, the width of the clamping plate 21 is greater than or equal to the minimum spacing between the two limit plates 12 in the covering section. At this time, the highest point of the spring is higher than the highest point of the clamping and conveying mechanism 1 and / or the lowest point of the spring is lower than the lowest point of the clamping and conveying mechanism 1. At this time, the clamping plate 21 clamps the spring protruding from the clamping and conveying mechanism 1 to pull the spring out of the clamping and conveying mechanism 1.

[0047] Furthermore, it also includes an adjusting mechanism 3, and the adjusting mechanism 3 is used to adjust the distance between the two groups of the conveyor belts / conveyor chains 11 in the clamping conveying mechanism 1.

[0048] More specifically, by providing the adjustment mechanism 3, the compression degree of the spring by the compression and conveying mechanism 2 can be adjusted, which is conducive to conveying springs with different compression amounts.

[0049] Furthermore, the adjustment mechanism 3 includes a base frame 31, a sliding frame 32 and a screw 33. The base frame 31 is fixedly arranged, and the two sliding frames 32 are respectively slidably connected to the base frame 31. The screw 33 is threadedly connected to at least one of the sliding frames 32. The rotation of the screw 33 drives the two sliding frames 32 to be relatively close or relatively far away, and the two groups of the conveyor belts / conveyor chains 11 are respectively installed on the two sliding frames 32.

[0050] More specifically, by setting a screw 33, the distance between the two sliding frames 32 can be adjusted by rotating the screw 33, so that the opening size of the clamping conveying mechanism 1 installed on the sliding frame 32 can be adjusted, thereby realizing that the adjusting mechanism 3 adjusts the distance between the two groups of conveyor belts / conveyor chains of the compression conveying mechanism 2.

[0051] Furthermore, the spacing between the limiting plates 12 can be adjusted independently relative to the conveyor belt / conveyor chain 11 .

[0052] More specifically, the spacing between the limit plates 12 can be adjusted independently relative to the conveyor belt / conveyor chain 11, so that the spacing between the limit plates 12 and the conveyor belt / conveyor chain 11 is adjustable, which is beneficial for the subsequent separation of the spring from the conveying surface of the conveyor belt / conveyor chain 11.

[0053] It should be noted that, in one embodiment, a long slot is provided on the limiting plate 12, and the limiting plate 12 is fixedly installed through the long slot so that the position of the limiting plate 12 is adjustable.

[0054] More specifically, by providing a long slot (not shown in the figure), the position of the limiting plate 12 can be adjusted.

[0055] 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 utility model.
