[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-6 As shown, a spring bagging device includes a frame 1. A spring manufacturing mechanism 2 is mounted on the upper right side of the frame 1. A spring conveying mechanism is located in the middle of the frame 1. The spring conveying mechanism includes several sets of sprockets 7. Each set of sprockets 7 includes two sprockets 7 arranged front and rear. Chains 8 connect the sprockets 7 on the same side. Several support bars 9 are installed between the two chains 8 on the front and rear sides. The support bars 9 are arranged parallel to each other and perpendicular to the chains 8. The distance between two adjacent support bars 9 is less than the diameter of the spring, so that the two adjacent support bars 9 can support the spring. A synchronous shaft connects the two front and rear opposing sprockets 7. One set of sprockets 7 is externally driven by a motor, which drives the chain 8 to rotate, thereby moving the support bars 9 to convey the spring.

[0023] A support plate 10 is installed on the frame 1. The support plate 10 is located at the lower end of the upper part of the chain 8 and supports the spring that is transported by the support bar 9 driven by the chain 8.

[0024] A transfer mechanism is provided between the spring manufacturing mechanism 2 and the spring conveying mechanism. The transfer mechanism includes a drive shaft 3, and several transfer plates 4 are connected to the outer periphery of the drive shaft 3. A groove 5 is formed on the outer side of the transfer plate 4, and an electromagnet 6 is installed at the bottom of the groove 5. The drive shaft 3 can drive the transfer plate 4 to rotate, and the springs produced by the spring manufacturing mechanism 2 fall into the transfer plate 4 that has rotated to the top. The spring falls into the groove 5, and the electromagnet 6 is energized to generate magnetism to attract the spring. When the transfer plate 4 rotates to the bottom, the electromagnet 6 is de-energized and loses its magnetic force, causing the spring to fall onto the spring conveying mechanism.

[0025] A guide roller 13 and a guide frame 12 are installed on the side of the frame 1. The guide roller 13 is located above the guide frame 12. A guide device 14 is also installed on the side of the frame 1. Part of the guide device 14 is located inside the guide frame 12. Two folding plates 23 are installed on the side of the guide frame 12 near the frame 1. The ends of the two folding plates 23 away from the guide frame 12 are close to each other.

[0026] The fabric guide 14 includes a guide block 48, the cross-sectional shape of which is similar to that of the fabric guide frame 12. A distribution block 24 is connected to the upper part of the guide block 48, the cross-section of which is triangular. A positioning block 25 is connected to the lower part of the guide block 48. The fabric guide roller 13 guides the non-woven fabric in, and the fabric guide 14 separates the folded non-woven fabric, so that the non-woven fabric enters between the fabric guide frame 12 and the fabric guide 14 in an open shape and moves downward.

[0027] A push spring mechanism 19 is provided on the frame 1 at the position corresponding to the folding plate 23. The push spring mechanism 19 includes a support platform 26. A front baffle 30 and a rear baffle 28 are provided on the support platform 26. The front baffle 30 and the rear baffle 28 are parallel. An inlet seat 32 is provided on the side of the front baffle 30 near the guide frame 12. The inlet seat 32 is located between the two folding plates 23. An opening 31 is provided on the front baffle 30 at the position corresponding to the inlet seat 32. A push block 29 is provided on the rear baffle 28 at the position corresponding to the opening 31. A push cylinder 27 is provided on the support platform 26. The push cylinder 27 is driven and connected to the push cylinder 28. Two pressure plates 34 are provided between the front baffle 30 and the rear baffle 28. A pressure cylinder 33 is provided on the support platform 26. The pressure cylinder 33 is driven and connected to the pressure plates 34. A guide plate 11 is provided at one end of the spring conveying mechanism near the guide frame 12. The guide plate 11 is arc-shaped and its outlet is located above the spring push mechanism 19. The outlet is aligned with the area enclosed by the front baffle 30, the rear baffle 28 and the two pressure plates 34.

[0028] A spring conveying mechanism transports springs, which, guided by guide plate 11, fall into spring-pushing mechanism 19. Pressing cylinder 33 drives pressing plate 34 closer together, compressing the spring. Pushing cylinder 27 drives push block 29 to move towards fabric frame 12, pushing the compressed spring through opening 31 to inlet seat 32, and then into guide block 48. The spring then springs back up, its two ends abutting against guide block 48. A pressing mechanism 15 is mounted on frame 1, part of which is located within guide block 48. The pressing mechanism 15 presses the spring within guide block 48 downwards. The spring enters positioning block 25. The pressing mechanism 15 can employ a crank-slider structure, using guide block 48 to guide the slider.

[0029] Below the guide frame 12 are a longitudinal welding mechanism 16 and a transverse welding mechanism 17. The transverse welding mechanism 17 is located below the longitudinal welding mechanism 16. The longitudinal welding mechanism 16 includes a template 35 and a welding head 38 arranged opposite each other. The template 35 and the welding head 38 are positioned near the positioning block 25. The template 35 is mounted on the frame 1. A welding cylinder 37 is mounted on the frame 1. The welding cylinder 37 drives the welding head 38. The welding cylinder 37 drives the welding head 38 to approach the template 35 to weld the nonwoven fabric, thereby closing the opening of the nonwoven fabric.

[0030] A deflection plate 36 is provided on the side of template 1 near the frame 1. The deflection plate 36 guides the two ends of the nonwoven fabric, causing the two ends to tilt and move closer to the same side.

[0031] Furthermore, the transverse welding cloth mechanism 17 includes a lifting platform 39, a welding cylinder 40 is provided on the upper part of the lifting platform 39, an mounting plate 41 is fixedly connected to the drive rod of the welding cylinder 40, a movable block 42 is slidably provided on the drive rod of the welding cylinder 40, a welding head 43 is provided on the side of the movable block 42 near the lifting platform 39, a pressing cylinder 44 is provided on the lifting platform 39, a template 45 is driven and connected to the pressing cylinder 44, the welding head 43 and the template 45 are arranged opposite each other on the left and right, the transverse welding cloth mechanism 17 also includes a lifting cylinder 47, the lifting cylinder 47 is located below the lifting platform 39, and the lifting cylinder 47 is driven and connected to the lifting platform 39.

[0032] Welding head 43 and template 45 are positioned close to each other, contacting both sides of the nonwoven fabric to perform transverse welding. This fixes the spring inside the nonwoven fabric. Simultaneously, lifting cylinder 47 drives lifting platform 39 to descend, thereby using the clamping of the nonwoven fabric by welding head 43 and template 45 to pull the nonwoven fabric downwards.

[0033] Furthermore, the transverse welding cloth mechanism 17 also includes a guide column 46, which passes through the lifting platform 39 and guides the lifting platform 39 as it rises and falls.

[0034] Furthermore, two conductive plates 21 arranged opposite each other are positioned in the middle of the spring conveying mechanism. A guide block 20 is located on the right side of the conductive plates 21, and a cooling fan 22 is installed on the frame 1 above and to the right of the conductive plates 21. After being guided by the guide block 20, the spring enters the conductive plates 21. After the two ends of the spring contact the conductive plates 21, they are heated by electricity, thus completing the heat treatment. The cooling fan 22 cools the heat-treated spring. An outlet mechanism 18 is located on the lower left side of the frame 1. The outlet mechanism 18 is used to export the bagged springs for conveying to the next machine.
