Abstract
Description
Technical Field
[0001] The utility model relates to a push spring mechanism for welding high-compression pocket springs, which belongs to the field of spring mechanical technology. This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on November 6, 2023, with application number CN202311463186X and invention name "A push spring and welding device for high-compression pocket springs", the entire contents of which are incorporated by reference in this application. Background Art
[0002] The pocket springs used in mattresses are springs that are placed in non-woven bags. In production, the springs processed by the spring forming device pass through the spring compression mechanism and the spring feeding mechanism, and are compressed and transported to the spring bagging device. The springs will be wrapped with non-woven fabric by the spring bagging device. After each spring is wrapped, a bag opening must be welded. When the pocket spring is a high compression spring, the spring is highly compressed and has a relatively large elastic force. It is easy to bend and deform in the bag, and cannot be placed properly in the bag, which affects the bagging quality.
[0003] The previously applied patent "Application number: CN202311463186X, invention name: A push spring and welding device for high-compression bagged springs" discloses a push spring mechanism, including two groups of oppositely arranged side plates, and the first transmission chain and the second transmission chain are respectively provided on the opposite sides of the two groups of side plates. The first transmission chain is arranged above the second transmission chain, and a number of groups of upper push spring rods are arranged between the two groups of the first transmission chains, and a number of groups of lower push spring rods matching the upper push spring rods are arranged between the two groups of the second transmission chains. Every two adjacent groups of upper push spring rods and their corresponding two groups of lower push spring rods form a limit interval.
[0004] The above-mentioned prior patent application still has a defect, that is, if the distance between two adjacent sets of push spring rods is set too small, although the spring can be clamped to prevent it from bending and deforming in the cloth bag, the cloth bag wrapping the spring will be too tight and will not meet the production requirements; if the distance between two adjacent sets of push spring rods is set too large, the spring will not be clamped to prevent it from bending and deforming in the cloth bag.
[0005] Therefore, how to provide a high-compression pocket spring welding push spring mechanism that can clamp the spring so that it is not easy to bend and deform in the bag and adjust the tightness of the bag is the research purpose of the utility model. Utility Model Content
[0006] In view of the deficiencies of the above-mentioned technology, the utility model provides a spring pushing mechanism for welding high-compression bagged springs, which pushes the high-compression bagged springs through a spring pushing rod group consisting of two spring clamping rods and a cloth pulling rod, thereby clamping the springs so that they are not easily bent and deformed in the cloth bag and adjusting the tightness of the cloth bag.
[0007] In order to solve the existing technical problems, the technical solution adopted by the utility model is:
[0008] A push spring mechanism for welding high-compression bagged springs, characterized in that: it comprises two groups of oppositely arranged side plates, and the first transmission chain and the second transmission chain are respectively provided on the opposite sides of the two groups of side plates, the first transmission chain is arranged above the second transmission chain, and a plurality of groups of upper push spring rod groups are arranged between the two groups of the first transmission chains, and a plurality of groups of lower push spring rod groups matching the upper push spring rod groups are arranged between the two groups of the second transmission chains, and a limit interval is formed between each group of the upper push spring rod groups and its corresponding lower push spring rod groups; each group of the upper push spring rod groups or the lower push spring rod groups is respectively provided with two clamping spring rods and a cloth pulling rod, and the cloth pulling rod is arranged at the front ends of the two clamping spring rods; the two groups of the first transmission chains are linked to each other by a first transmission shaft, and the two groups of the second transmission chains are linked to each other by a second transmission shaft, and the first transmission shaft and the second transmission shaft are connected to a servo motor that drives them to operate through a synchronous belt.
[0009] Furthermore, several groups of the push-up spring rod groups are distributed on the first transmission chain along the circumference of the first transmission chain; and several groups of the push-down spring rod groups are distributed on the second transmission chain along the circumference of the second transmission chain.
[0010] Furthermore, the first transmission shaft and the second transmission shaft are rotatably disposed on opposite sides of the two groups of side plates through bearings respectively.
[0011] Furthermore, the first transmission chain is configured to rotate clockwise, and the second transmission chain is configured to rotate counterclockwise.
[0012] The utility model has the beneficial effect that the high compression bag spring is pushed by the spring pushing rod group composed of two spring clamping rods and a cloth pulling rod, which can not only clamp the spring so that it is not easy to bend and deform in the cloth bag, but also adjust the tightness of the cloth bag.

[0020] like Figure 1-5 As shown, a push spring mechanism for welding high-compression bagged springs is characterized in that: it includes two groups of oppositely arranged side plates 1, and the first transmission chain 2 and the second transmission chain 3 are respectively provided on the opposite sides of the two groups of side plates 1, the first transmission chain 2 is arranged above the second transmission chain 3, and a plurality of groups of upper push spring rod groups 4 are arranged between the two groups of the first transmission chains 2, and a plurality of groups of lower push spring rod groups 5 matching the upper push spring rod groups 4 are arranged between the two groups of the second transmission chains 3, and a limiting interval is formed between each group of the upper push spring rod groups 4 and its corresponding lower push spring rod groups 5, which clamps the high-compression bagged spring and pushes it toward the welding mechanism; each group of the upper push spring rod groups 4 or the lower push spring rod groups 5 are respectively provided with two clamps A spring rod 401 and a cloth pulling rod 402, the two spring clamping rods 401 are used to clamp the two sides of the high compression bag spring to prevent it from bending and deforming in the cloth bag. The cloth pulling rod 402 is arranged at the front end of the two spring clamping rods 401. The cloth pulling rod 402 is used to adjust the tightness of the cloth bag. The larger the distance between the cloth pulling rod 402 and the spring clamping rod 401 adjacent to it, the looser the cloth bag is, and the smaller the distance between the cloth pulling rod 402 and the spring clamping rod 401 adjacent to it, the tighter the cloth bag is. The two groups of the first transmission chains 2 are linked to each other through the first transmission shaft 6, and the two groups of the second transmission chains 3 are linked to each other through the second transmission shaft 7. The first transmission shaft 6 and the second transmission shaft 7 are connected to the servo motor 8 driving them to operate through a synchronous belt.
[0021] In this embodiment, preferably, several groups of the push-up spring rod groups 4 are distributed on the first transmission chain 2 along the circumference of the first transmission chain 2, and the first transmission chain 2 drives the push-up spring rod groups 4 to operate; several groups of the push-down spring rod groups 5 are distributed on the second transmission chain 3 along the circumference of the second transmission chain 3, and the second transmission chain 3 drives the push-down spring rod groups 5 to operate.
