DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0025] A production method of a spring mattress, comprising the following steps: a 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 circle of springs. The steel frames and the springs are fixed by clamping nails. A substrate is installed outside the steel frames, and the substrate is connected to the steel frames. The substrate is fixed to the upper and lower ends of the outermost circle of springs by clamping nails to ensure the firmness of the substrate installation. A glue coating mechanism is used to coat glue on the outside of the substrate, and a surface fabric is laid on the outside of the substrate and compacted. The surface fabric is compacted to make the glue fully contact with the substrate and the fabric, so that the two can be better bonded. Specifically, glue is first coated on the outside of the upper substrate, the surface fabric is laid, and the surface fabric is compacted. The spring bed net is turned over, the lower substrate is turned over to the upper side, glue is coated on the outside of the substrate, the surface fabric is laid, and the surface fabric is compacted. The spring bed net is placed in a covering, and the outer edge of the surface fabric is sewn with the outer edge of the covering by a covering machine. The obtained mattress after sewing is detected, and the mattress that passes the detection is packaged and stored uniformly.

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

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

[0028] The detection mainly detects the surface quality of the surface fabric and the covering by a visual detection mechanism, and detects the sewing position of the surface fabric and the covering.

[0029] As Figures 1-5 shown, the gluing mechanism comprises a cabinet 1, a conveying mechanism 2 is arranged at the lower part of the cabinet 1, a guide rod one 5 and a guide rod two 6 are connected between the front and rear side walls of the cabinet 1, the guide rod one 5 and the guide rod two 6 are parallel, two sliding blocks one 7 are arranged on the guide rod one 5, a driving motor 18 is arranged at the middle position of the guide rod one 5, the two sliding blocks one 7 are located at the two sides of the driving motor 18, a spray head one 8 and a spray head two 9 are arranged on the sliding blocks one 7, the spray head one 8 is located at the inner side, a rack 11 is arranged on the sliding blocks one 7, the racks 11 on the two sliding blocks one 7 are respectively located at the left and right sides of a driving gear 10, the two racks 11 are engaged with the driving gear 10; a sliding block two 12 is arranged on the guide rod two 6, a plurality of spray head threes 13 are arranged on the sliding block two 12, the interval between the adjacent two spray head threes 13 is equal, a storage tank 3 and three liquid supply pumps 4 are arranged at the upper part of the cabinet 1, the input ends of the three liquid supply pumps 4 are connected with the storage tank 3, the output ends of the three liquid supply pumps 4 are connected with the spray head one 8, the spray head two 9 and the spray head three 13 through pipelines respectively, so as to control the glue supply amount of the spray head one 8, the spray head two 9 and the spray head three 13 respectively.

[0030] The spring bed net is conveyed into the cabinet 1 by the conveying mechanism 2, so that the front end of the substrate 33 on the spring bed net reaches below the sliding blocks one 7 and stays for a certain period of time. The liquid supply pumps 4 supply glue to the spray head one 8 and the spray head two 9, and the spray head one 8 and the spray head two 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 the two sides, so as to drive the sliding blocks one 7 to move along the guide rod one 5, so that the two relatively far away. The glue sprayed from the spray head one 8 and the spray head two 9 can form a horizontal section 34 on the substrate 33. And the moving range of the spray head one 8 covers the initial position of the spray head two 9, so that the glue sprayed at the spray head one 8 can be connected to the glue sprayed at the spray head two 9, so that the horizontal section 34 is continuous.

[0031] After completing the spraying of the horizontal section 34, the conveying mechanism 2 continues to convey the spring bed net, at this time the glue sprayed from the spray head one 8 and the spray head two 9 can be applied along the length direction of the substrate 33, so as to form a vertical section one 35 and a vertical section two 37 on the substrate 33. When the conveying mechanism 2 conveys the spring bed net to the rear end of the substrate 33 to reach below the sliding blocks one 7, it stays for a certain period of time. The driving motor 18 drives the driving gear 10 to rotate reversely, so that the two sliding blocks one 7 relatively close, so as to form a horizontal section 34 at the rear end of the substrate 33 through the spray head one 8 and the spray head two 9. After completion, the conveying mechanism 2 conveys the spring bed net to the next station.

[0032] The horizontal section 34 and the vertical section one 35 form a rectangular structure covering the upper peripheral position of the substrate 33. Meanwhile, the horizontal section 34 and the vertical section one 35 form a rectangular structure with the vertical section two 37 along the length direction of the substrate 33, filling the vacancy inside the rectangular structure. In this way, the substrate 33 and the surface fabric have more glue between them, so that they can be bonded together.

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

[0034] The conveying mechanism 2 comprises a support frame 19, a plurality of conveying rollers 20 are rotatably arranged on the support frame 19, two transmission sprockets 21 are coaxially connected to each conveying roller 20, a transmission chain 22 is connected between the corresponding transmission sprockets 21 of adjacent two conveying rollers 20, and the outermost transmission sprocket 21 is driven by an external motor. The outermost transmission sprocket 21 is driven to rotate by the external motor, and the adjacent transmission sprockets 21 are driven to rotate in turn.

[0035] The transmission chain 22 is connected between the inner transmission sprockets 21 of the first conveying roller 20 and the second conveying roller 20, the transmission chain 22 is connected between the outer transmission sprockets 21 of the second conveying roller 20 and the third conveying roller 20, and the transmission chain 22 is connected between the inner transmission sprockets 21 of the third conveying roller 20 and the fourth conveying roller 20. In this way, the conveying rollers 20 are synchronously rotated, and the spring bed net can be effectively conveyed.

[0036] Further, the front side wall of the case 1 is provided with a mounting seat 14, the mounting seat 14 is rotatably provided with a rotating disc 15, the rotating disc 15 is coaxially connected with a crank 16, the crank 16 is rotatably connected with a connecting rod 17 at the end away from the rotating disc 15, the other end of the connecting rod 17 is hingedly connected with the sliding block two 12, and the rotating disc 15 is driven by a driving mechanism. The front side wall of the case 1 is provided with a guide sleeve 24, the driving mechanism comprises a transmission shaft 25, the transmission shaft 25 is arranged through the guide sleeve 24, the transmission shaft 25 can rotate and lift in the guide sleeve 24, the transmission shaft 25 is connected with a transmission gear 26 at the upper end, the rotating disc 15 is coaxially connected with a driven gear 32, the transmission gear 26 is engaged with the driven gear 32, the transmission shaft 25 is connected with a transmission bevel gear 27 at the lower end, and the conveying roller 20 opposite to the transmission shaft 25 is coaxially connected with a driving bevel gear 23, the transmission bevel gear 27 is engaged 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 cooperation with the transmission bevel gear 27, and the transmission shaft 25 drives the rotating disc 15 to rotate through cooperation with the driven gear 32. The rotating disc 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 at the nozzle three 13 can form the wave section 36 on the substrate 33, so as to increase the amount of glue in the width direction of the substrate 33, so that the area of contact between the substrate 33 and the surface layer surface in the width direction is increased, and a better bonding effect can be obtained.

[0038] Further, since the slider two 12 only needs to follow the movement of the spring bed net at the front end and the rear end of the substrate 33 to the position below the slider one 7, in order to reduce wear and tear and consumption, the slider two 12 can be kept relatively fixed at other times. The transmission shaft 25 is connected with a support ring 28, a lifting mechanism 29 is installed on the front side wall of the machine box 1, the lifting mechanism 29 is driven to be 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 machine box 1, and the pressing plate 31 is located above the support ring 28. When the slider two 12 does not need to follow the movement, the lifting mechanism 29 controls the support plate 30 to rise, the support plate 30 supports the support ring 28 to drive the transmission shaft 25 to rise. The transmission bevel gear 27 is separated 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 clamp the support ring 28, thereby limiting 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 of the transmission shaft 25. By limiting the rotation of the transmission shaft 25, the position of the driven gear 32 is also limited, thereby fixing the position of the slider two 12.

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

[0040] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as the protection scope of the present application.
