Description

Technical Field

[0001] The utility model relates to the technical field of spring cushion production machinery, in particular to a production and conveying mechanism for double-row bagged springs. Background Art

[0002] Spring cushions are a product commonly used in the production of spring sofas and spring mattresses. They are typically produced by gluing or welding together multiple pocket spring strips, which requires spring cushion production machinery.

[0003] There are generally two types of existing spring cushion production machines. One type feeds spring strips one by one into a gluing machine or welding machine for bonding or welding to form a cushion. The other type feeds a whole continuous spring strip continuously by bending it, and then welds adjacent pocket springs.

[0004] However, both methods are performed by welding one by one, so the speed is slow. Therefore, we propose to connect two pocket spring strings together to form a double-row pocket spring, and then process them.

[0005] At this time, a conveying mechanism is needed that can fix two bagged springs together to form a double-row bagged spring during the conveying process. Utility Model Content

[0029] 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.

[0030] like Figures 1 to 8 The utility model is a double-row pocket spring production conveying mechanism, comprising a conveying mechanism 1 and a welding mechanism 2;

[0031] Conveying mechanism 1, the conveying mechanism 1 is used to convey the bagged spring strings, and two conveying mechanisms 1 convey the two groups of bagged spring strings synchronously so that they are displaced side by side;

[0032] Welding mechanism 2: At least one welding mechanism 2 is provided between the two sets of conveying mechanisms 1, and is used to weld the two sets of bagged springs together;

[0033] The conveying mechanism 1 includes a chain / conveyor belt 11 and a fixing mechanism 12. At least one chain / conveyor belt 11 is used for cyclic conveying. The chain / conveyor belt 11 is provided with at least one fixing mechanism 12 for fixing the pocket springs on the pocket spring string.

[0034] During transportation, the present invention has the two groups of fixing mechanisms 12 of the conveying mechanism 1 corresponding one-to-one or at intervals to the springs of the bagged spring strings, so that the two groups of bagged spring strings are conveyed side by side and under the limit of the fixing mechanism 12, the two groups of bagged spring strings are in a weldable state (specifically, the two groups of bagged spring strings are in an expanded state, so that the non-woven fabric between the bagged springs is opened to facilitate subsequent welding). At this time, the welding mechanism 2 continuously or at intervals welds the non-woven fabric between the two groups of bagged spring strings together to form a double-row bagged spring string, and the conveying mechanism 1 continues to convey and output the double-row bagged spring string.

[0035] It should be noted that the bagged spring string being in a weldable state not only includes a fully expanded state, but only requires that the spring string be expanded to a state where the welding mechanism can perform welding.

[0036] The advantages of the present invention are as follows: 1. By setting up two groups of conveying mechanisms, each group of conveying mechanisms is provided with a fixing mechanism, so that the two groups of bagged spring strings are unfolded and conveyed side by side, and then the two groups of bagged spring strings conveyed side by side are welded together by the welding mechanism, thus realizing the production of double-row bagged spring strings during the conveying process; 2. By setting up the fixing mechanism, it is ensured that the bagged spring strings remain in a weldable state during the conveying process, which is conducive to the welding mechanism to weld the two groups of bagged spring strings together.

[0037] Furthermore, the distance between two adjacent groups of welding mechanisms 2 is adjustable.

[0038] More specifically, the spacing between two adjacent sets of welding mechanisms 2 is adjustable so that when multiple sets of welding mechanisms 2 are used simultaneously, they can adapt to pocket spring strings with different spacings, which is beneficial for producing and conveying double-row pocket spring strings of different sizes.

[0039] Furthermore, the distance between the two conveying mechanisms 1 is adjustable.

[0040] More specifically, the distance between the two conveying mechanisms 1 is adjustable, so that the two sets of conveying mechanisms 1 can convey pocket spring strings of different diameters, which is beneficial to the production of double-row pocket spring strings of different diameters.

[0041] Furthermore, the fixing mechanism 12 is a magnetic suction cup.

[0042] More specifically, the magnetic suction cup has the advantages of stable adsorption and easy detachment, and is separated by the output of the subsequent double-row pocket spring string.

[0043] Furthermore, the conveying mechanism 1 is composed of two oppositely arranged chains / conveyor belts 11, and the two conveying mechanisms 1 are oppositely arranged.

[0044] Furthermore, the welding mechanism 2 includes a cutting die 21 and a welding knife 22, the cutting die 21 is located between the two chains / conveyor belts 11 of one of the conveying mechanisms 1, and the welding knife 22 is located between the two chains / conveyor belts 11 of the other conveying mechanism 1, and the cutting die 21 and the welding knife 22 can be relatively close to or far away from each other.

[0045] like Figures 1 to 3 The figure shows one embodiment of the present invention. In this embodiment, a cutting die 21 and a welding knife 22 are provided between the two chains / conveyor belts 11. The cutting die 21 and the welding knife 22 are extended and retracted from between the two chains / conveyor belts 11 for welding.

[0046] In this usage, the fixing mechanism 12 is a magnetic suction cup, and the springs of the pocket spring string are adsorbed on the magnetic suction cup. At this time, the spring axis of the pocket spring string is parallel to the supporting surface of the magnetic suction cup.

[0047] Furthermore, the two groups of conveying mechanisms 1 are arranged in parallel or staggered relative to each other, and the fixing mechanism 12 fixes the bagged springs so that the two groups of bagged spring strings conveyed by the two groups of conveying mechanisms 1 are conveyed side by side.

[0048] As shown in FIG7 , it is one embodiment of the present invention. In this embodiment, two sets of the conveying mechanisms 1 are arranged in parallel and the fixing mechanism 12 fixes one end of the bagged spring string.

[0049] As shown in FIG8 , it is one embodiment of the present invention. In this embodiment, the two sets of the conveying mechanisms 1 are relatively staggered and the fixing mechanism 12 fixes one end of the bagged spring string.

[0050] Furthermore, the two groups of conveying mechanisms 1 are arranged in parallel, and each group of conveying mechanisms 1 includes two or more groups of relatively arranged chains / conveyor belts 11, and each group of chains / conveyor belts 11 is provided with at least one fixing mechanism 12.

[0051] As shown in Figures 4 to 6, one embodiment of the present invention is shown. In this embodiment, two groups of conveying mechanisms 1 have parallel holes, and each group of conveying mechanisms 1 is configured to clamp the bagged spring string through two chains / conveyor belts 11 and a fixing mechanism 12.

[0052] 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.
