Description

Technical Field

[0001] The present invention relates to the technical field of mattresses, and more specifically, to a production method of a spring mattress. Background Art

[0002] With the improvement of people's living quality, more attention is paid to sleep quality. A good mattress can not only enable people to have a comfortable sleep, but also be of great benefit to the body. If the mattress is not ideal, it will not only compress the back nerves of the human body, but also affect the normal blood circulation. In the long run, it will cause backache and sciatica pain. Mattresses mainly include springs, bottom materials and surface fabrics, among which the surface fabric is bonded to the bottom material by glue. The existing installation method is that workers use a spray gun to spray glue on the bottom material. This spraying method will cause the glue to be unevenly distributed, and the amount of glue used cannot be accurately controlled, resulting in inconsistent production quality of each mattress, and even the quality of the front and back sides of each mattress cannot be unified. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a production method of a spring mattress.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

Detailed implementation manners

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] A production method of a spring mattress includes the following steps. The spring bed net is produced by a spring making machine and a net stringing machine. Steel frames are installed at the upper and lower ends of the spring bed net, and the steel frames are fixed to the upper and lower ends of the outermost springs; the steel frames and the springs are fixed by clip nails. A substrate is installed outside the steel frame, and the substrate is connected to the steel frame; the substrate is fixed to the steel frame and the upper and lower ends of the outermost springs by clip nails to ensure the firmness of the substrate installation. Glue is coated on the outside of the substrate through a gluing mechanism, and the surface fabric is laid flat on the outside of the substrate and compacted. By compacting the surface fabric, the glue can be fully contacted with the substrate and the fabric, so that the two can be better bonded. Specifically, first, glue is coated on the outside of the upper substrate, the surface fabric is laid, and compacted. Then the spring bed net is turned over, and the lower substrate is turned to the upper side. Then glue is coated on the outside of this substrate, the surface fabric is laid, and compacted. The spring bed net is placed into the edge binding, and the outer edge of the surface fabric is sewn to the outer edge of the edge binding by an edge binding machine. The obtained mattress after sewing is inspected, and the qualified mattresses are packaged and stored uniformly.

[0026] Further, the surface fabric is a composite fabric, which is composed of fiber cotton and non-woven fabric.

[0027] Further, the glue is polyurethane glue or water-based glue.

[0028] The inspection is mainly to inspect the surface quality of the surface fabric and the edge binding through a visual inspection mechanism, and to inspect the sewing part of the surface fabric and the edge binding.

[0029] As shown Figures 1-5 in the figure, the glue applying mechanism includes a chassis 1. A conveying mechanism 2 is arranged at the lower part of the chassis 1. A first guide rod 5 and a second guide rod 6 are connected between the front and rear side walls of the chassis 1. The first guide rod 5 and the second guide rod 6 are parallel to each other. There are two first sliders 7 sliding on the first guide rod 5. There is a driving motor 18 at the middle position of the first guide rod 5. The two first sliders 7 are located on both sides of the driving motor 18. A first nozzle 8 and a second nozzle 9 are arranged on the first slider 7. The first nozzle 8 is located on the inner side. A rack 11 is installed on the first slider 7. The racks 11 on the two first sliders 7 are respectively located on the left and right sides of the driving gear 10. Both of the two racks 11 are engaged with the driving gear 10. A second slider 12 is arranged on the second guide rod 6. A number of third nozzles 13 are arranged on the second slider 12. The distance between adjacent two third nozzles 13 is equal. A storage tank 3 and three liquid supply pumps 4 are arranged at the upper part of the chassis 1. The input ends of the three liquid supply pumps 4 are all connected to the storage tank 3. The output ends of the three liquid supply pumps 4 are respectively connected to the first nozzle 8, the second nozzle 9 and the third nozzles 13 through pipelines, so as to respectively control the glue supply amounts of the first nozzle 8, the second nozzle 9 and the third nozzles 13.

[0030] The spring bed net is conveyed into the chassis 1 through the conveying mechanism 2. After the front end of the substrate 33 on the spring bed net reaches below the first slider 7, it stays for a certain time. The liquid supply pumps 4 supply glue to the first nozzle 8 and the second nozzle 9. The first nozzle 8 and the second nozzle 9 apply glue to the substrate 33. At the same time, the driving motor 18 drives the driving gear 10 to rotate. The driving gear 10 acts on the racks 11 on both sides, so as to drive the first sliders 7 to move along the first guide rod 5, making the two move relatively away from each other. The glue ejected from the first nozzle 8 and the second nozzle 9 can form a horizontal section 34 on the substrate 33. And the moving range of the first nozzle 8 covers the initial position of the second nozzle 9, so that the glue ejected from the first nozzle 8 can be connected to the glue ejected from the second nozzle 9, making the horizontal section 34 continuous.

[0031] After the spraying of the horizontal section 34 is completed, the conveying mechanism 2 continues to convey the spring bed net. At this time, the glue ejected from the first nozzle 8 and the second nozzle 9 can be coated along the length direction of the substrate 33, so as to form a first vertical section 35 and a second vertical section 37 on the substrate 33. When the conveying mechanism 2 conveys the spring bed net until the rear end of the substrate 33 reaches below the first slider 7, it stays for a certain time. The driving motor 18 drives the driving gear 10 to rotate in the reverse direction, making the two first sliders 7 move relatively close to each other, so as to form a horizontal section 34 at the rear end of the substrate 33 through the first nozzle 8 and the second nozzle 9. After completion, the conveying mechanism 2 conveys the spring bed net to the next working station.

[0032] The horizontal segment 34 and the first vertical segment 35 form a rectangular structure that covers the outer peripheral position of the upper part of the substrate 33. At the same time, there is a second vertical segment 37 along the length direction of the substrate 33 inside the rectangular structure formed by the horizontal segment 34 and the first vertical segment 35, filling the vacant position inside the rectangular structure. With such a setting, there is more glue between the substrate 33 and the surface fabric, enabling the two to be bonded together.

[0033] The glue sprayed by the third nozzle 13 can also be coated along the length direction of the substrate 33, increasing the amount of glue on the substrate 33 to enhance the bonding property.

[0034] The conveying mechanism 2 includes a support frame 19. A number of conveying rollers 20 are rotatably arranged on the support frame 19. Two driving sprockets 21 are coaxially connected to each conveying roller 20. A driving chain 22 is connected between the corresponding driving sprockets 21 of two adjacent conveying rollers 20. The outermost driving sprocket 21 is driven by an external motor. By driving the outermost driving sprocket 21 to rotate with the external motor, the outermost driving sprocket 21 drives the adjacent driving sprocket 21 to rotate, and then transmits in sequence.

[0035] A driving chain 22 is connected between the inner driving sprockets 21 of the first conveying roller 20 and the second conveying roller 20, a driving chain 22 is connected between the outer driving sprockets 21 of the second conveying roller 20 and the third conveying roller 20, and a driving chain 22 is connected between the inner driving sprockets 21 of the third conveying roller 20 and the fourth conveying roller 20, and so on, ensuring that each conveying roller 20 rotates synchronously and can effectively convey the spring bed net.

[0036] Furthermore, a mounting seat 14 is installed on the front side wall of the chassis 1. A turntable 15 is rotatably arranged on the mounting seat 14. A crank 16 is coaxially connected to the turntable 15. One end of the crank 16 far from the turntable 15 is rotatably connected to a connecting rod 17. The other end of the connecting rod 17 is hinged to the second slider 12. The turntable 15 is driven by a driving mechanism. A guide sleeve 24 is installed on the front side wall of the chassis 1. The driving mechanism includes a transmission shaft 25. The transmission shaft 25 passes through the guide sleeve 24. The transmission shaft 25 can rotate and lift inside the guide sleeve 24. A transmission gear 26 is connected to the upper end of the transmission shaft 25. A driven gear 32 is coaxially connected to the turntable 15. The transmission gear 26 meshes with the driven gear 32. A driving bevel gear 27 is connected to the lower end of the transmission shaft 25. A driving bevel gear 23 is coaxially connected to the conveying roller 20 opposite to the position of the transmission shaft 25. The driving bevel gear 27 meshes with the driving bevel gear 23.

[0037] When the conveying roller 20 drives the spring bed net to move, the driving bevel gear 23 drives the transmission shaft 25 to rotate through the cooperation with the transmission bevel gear 27, and the transmission shaft 25 then drives the turntable 15 to rotate through the cooperation with the driven gear 32. The turntable 15 drives the crank 16 to rotate, and the crank 16 drives the slider two 12 to move back and forth along the guide rod two 6 through the connecting rod 17. Since the spring bed net is moving at this time, the glue sprayed from the nozzle three 13 can form a wave section 36 on the substrate 33, thereby increasing the amount of glue in the width direction of the substrate 33, increasing the contact area between the substrate 33 and the surface layer in the width direction, and obtaining a better bonding effect.

[0038] Further, since the slider two 12 only needs to follow up during the period when the front end and the rear end of the substrate 33 of the spring bed net reach below the slider one 7, in order to reduce wear and consumption, the slider two 12 can remain relatively fixed at other times. A support ring 28 is connected to the transmission shaft 25, a lifting mechanism 29 is installed on the front side wall of the chassis 1, the lifting mechanism 29 is drivingly connected with a support plate 30, the support plate 30 is located below the support ring 28, and a pressing plate 31 is also installed on the front side wall of the chassis 1, and the pressing plate 31 is located above the support ring 28. When the slider two 12 does not need to follow up, the lifting mechanism 29 controls the support plate 30 to rise, and the support plate 30 supports the support ring 28 to drive the transmission shaft 25 to rise. The transmission bevel gear 27 disengages from the driving bevel gear 23 as the transmission shaft 25 rises. The support plate 30 drives the support ring 28 to rise so that the upper end surface of the support ring 28 abuts against the lower end surface of the pressing plate 31, and the pressing plate 31 and the support plate 30 jointly act to clamp the support ring 28, thereby restricting the rotation of the transmission shaft 25. The thickness of the transmission gear 26 is set to be greater than the thickness of the driven gear 32, so that the transmission gear 26 can maintain the meshing state with the driven gear 32 during the lifting process of the transmission shaft 25. By restricting the rotation of the transmission shaft 25, that is, restricting the position of the driven gear 32, the position of the slider two 12 is fixed.

[0039] The lifting mechanism 29 can be a cylinder or a hydraulic cylinder.

[0040] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
