[0048] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to facilitate a clearer understanding of the technical ideas claimed for protection in the present invention.

[0049] like Figures 1 to 10 A mattress bonding method is shown, and the production process of this method includes the following steps:

[0050] Step 1: Weld two sets of non-woven fabrics together at one end, and then tighten the two sets of non-woven fabrics (such as Figure 2 As shown), go to step 2;

[0051] Step 2: After the first pocket spring string forming the mattress is input to the designated position, the first pocket spring string and / or two sets of non-woven fabrics are sprayed with glue (such as Figure 2 As shown), go to step 3;

[0052] Step 3: Transport the first string of pocket springs to the position of the two sets of non-woven fabrics so that the sides and both ends of the first string of pocket springs are bonded to the two sets of non-woven fabrics respectively (such as Figure 3 As shown), go to step 4;

[0053] Step 4: The next pocket spring string is input to the designated position, and then at least one of the pocket spring string, the previous pocket spring string and the two sets of non-woven fabrics is sprayed with glue (such as Figure 5 As shown), go to step 5;

[0054] Step 5: Transport the pocket spring string in the direction of the previous pocket spring string so that the pocket spring string is bonded to the previous pocket spring string and the two ends of the pocket spring string are bonded to the two sets of non-woven fabrics (such as Figure 6 As shown), go to step 6;

[0055] Step 6: Repeat steps 4 and 5 until the last pocket spring string of the mattress is bonded to the previous pocket spring string and the two ends of the pocket spring string are bonded to the two sets of non-woven fabrics (such as Figure 7 As shown), go to step 7;

[0056] Step 7: Spray glue on the last string of pocket springs and / or two sets of non-woven bags, and then compress at least the last string of pocket springs at the designated position (such as Figure 8 As shown), go to step 8;

[0057] Step 8: Weld and split the two sets of non-woven fabrics, then loosen the pocket spring string and non-woven fabric, and the pocket spring string rebounds so that the welded non-woven fabric is tightly bonded to the side of the pocket spring string, completing the bonding production of a mattress. At the same time, the two sets of non-woven fabrics are tensioned, waiting for the bonding of the next mattress (such as Fig. 9 As shown), go to step 9;

[0058] Step 9: Repeat steps 2 to 8 until all mattresses are bonded.

[0059] A mattress bonding method of the present invention continuously produces mattresses in which the non-woven fabrics on both sides are bonded to the internal pocket spring strings by bonding the non-woven fabrics on the sides of the first pocket spring string and bonding the non-woven fabrics on the sides of the last pocket spring string, thereby reducing subsequent bonding steps and improving production efficiency.

[0060] Furthermore, compressing at least the last string of pocket springs at the designated position specifically comprises synchronously conveying all the spring strings and non-woven fabrics to which the last string of pocket springs and non-woven fabrics have been bonded to the designated position, and then compressing at least the last string of pocket springs.

[0061] More preferably, conveying all pocket spring strings to a designated location can facilitate sufficient locations for welding and splitting the two groups of nonwoven fabrics.

[0062] The present invention also proposes Figures 1 to 6 The mattress bonding device of the present invention comprises a first conveying mechanism 1, a second conveying mechanism 2, a glue spraying mechanism 3 and a welding and cutting mechanism 4;

[0063] The first conveying mechanism 1 is provided at the input end of the second conveying mechanism 2 and is used to input the bagged spring string into the second conveying mechanism 2;

[0064] The second conveying mechanism 2 includes a second clamping conveyor belt 21 and a cloth-passing roller 22. The second clamping conveyor belt 21 is arranged at the output end of the first conveying mechanism 1. The second clamping conveyor belt 21 includes at least two second conveyor belts 23 arranged opposite to each other. The two second conveyor belts 23 can be relatively close to each other or away from each other. Each second conveyor belt 23 is at least correspondingly provided with a cloth-passing roller 22. The cloth-passing roller 22 is used to assist the non-woven fabric to enter the second conveyor belt 23;

[0065] A glue spraying mechanism 3, used for spraying glue on the pocket spring string and / or the non-woven fabric;

[0066] The welding and cutting mechanism 4 can weld and separate two groups of non-woven fabrics.

[0067] When the present invention is used, the two welded groups of non-woven fabrics are tensioned, the first spring string is input through the first conveying mechanism 1, and then the glue spraying mechanism 3 sprays glue on the spring string and / or the non-woven fabric, and then the first conveying mechanism 1 inputs the bagged spring string into the second conveying mechanism 2, so that the side and both ends of the first spring string are respectively bonded to the two groups of non-woven fabrics; the next spring string is input by the first conveying mechanism 1, and then the glue spraying mechanism 3 sprays glue on at least one of the spring string, the previous spring string and the non-woven fabric, and then the first conveying mechanism conveys the spring string to the second conveying mechanism 2 to fit and adhere to the previous spring string, and at the same time, the two ends of the spring string are respectively bonded to the two groups of non-woven fabrics; in this way Repeat until the last spring string is bonded, then the glue spraying mechanism sprays glue on the last spring string and / or two groups of non-woven fabrics, the second conveying mechanism 2 conveys all the spring strings to the specified position, and then the two second conveyor belts 23 are relatively close to compress the spring string, and then the welding and cutting mechanism 4 welds and cuts the two groups of non-woven fabrics to ensure that the two groups of non-woven fabrics at both ends of the cutting are in a welding state. After the welding and cutting actions are completed, the welding and cutting mechanism 4 loosens the two groups of non-woven fabrics and the two second conveyor belts 23 move away from each other to release the bagged spring string. At this time, the bagged spring string rebounds so that the welded non-woven fabric will be tightly bonded to the side of the best bagged spring string, thus completing the production of the bed net.

[0068] It should be noted that before bonding the first mattress, the welding and cutting mechanism 4 is required to weld the two ends of the two groups of non-woven fabrics, and then the two groups of non-woven fabrics are tensioned. When bonding the mattresses subsequently, since the two groups of non-woven fabrics have been welded and cut, it is only necessary to tension the two groups of non-woven fabrics for continuous production.

[0069] The advantages of the present invention are as follows: by providing a welding and slitting mechanism and a second conveyor belt that can be moved closer and farther away, two groups of non-woven fabrics can be welded together, and the two second conveyors enable the side surfaces of the first string of pocket springs to be bonded to the non-woven fabrics when the first string of pocket springs enters the two groups of non-woven fabrics, and at the same time, after the last string of pocket springs enters the non-woven fabric bag, the two groups of non-woven fabrics are bonded to the side surfaces of the last string of pocket springs through the cooperation of the welding and slitting mechanism and the second conveyor belt, thereby reducing the number of mattress sides that need to be bonded later, and effectively improving production efficiency; secondly, by providing a welding and slitting mechanism, the entire mechanical action can be continuous, which is conducive to large-scale production.

[0070] Furthermore, the cloth-passing roller 22 is arranged between the second conveyor belt 23 and the first conveying mechanism 1 , the glue spraying mechanism 3 is arranged between the cloth-passing roller 22 and the first conveying mechanism 1 , and the welding and cutting mechanism 4 is arranged between the cloth-passing roller 22 and the second conveyor belt 23 .

[0071] More specifically, in one embodiment of the present invention, in this embodiment, the number of the cloth-passing roller is one, and the cloth-passing roller 22 is arranged between the first conveying mechanism 1 and the second conveying belt 23, so that the first conveying mechanism 1 is laterally inputting the pocket springs into the second conveying belt 23 through the cloth-passing roller 22, so as to facilitate the bonding of the two ends of the pocket springs with the two groups of non-woven fabrics; the glue spraying mechanism 3 is arranged between the cloth-passing roller 22 and the first conveying mechanism 1, so that the glue spraying mechanism 3 can be moved laterally along the direction of the cloth-passing roller 22 to spray glue on the non-woven fabric or the pocket springs arranged between the two cloth-passing rollers 22 or the pocket spring string arranged in the first conveying mechanism 1; the welding and cutting mechanism 4 is arranged between the cloth-passing roller 22 and the second conveying belt 23. Every time the mattress after the last group of pocket spring strings are bonded needs to be cut into non-woven fabrics, the second conveying belt 23 is required to transport the pocket spring string into the second conveying belt 23, and the welding and cutting mechanism 4 then welds and cuts the non-woven fabrics.

[0072] Furthermore, the welding and cutting mechanism 4 includes a welding mechanism 41 and a cutting mechanism 42, at least one group of welding mechanisms 41 is arranged in parallel in a direction perpendicular to the conveying direction of the second conveying mechanism 2, each group of the welding mechanisms 41 includes a welding knife / heating wire 43 and a cutting die 44, the welding knife / heating wire 43 and the cutting die 44 are used together to weld two groups of non-woven fabrics, and the cutting mechanism 42 is used to separate the two groups of non-woven fabrics that have been welded along the welding direction of the welding mechanism 41.

[0073] More specifically, the welding mechanism 41 is provided to weld the two groups of non-woven fabrics, and the cutting mechanism 42 is provided to cut the two groups of non-woven fabrics after welding.

[0074] It should be noted that the welding mechanism 41 can be a structure with welding function such as a heating wire / welding knife 43 and a cutting die 44, or other structures with welding function, as long as it can cooperate with the cutting mechanism 42 to weld and cut the non-woven fabric.

[0075] Furthermore, the cutting mechanism 42 includes a cutter 45 and a cutter drive 47. Each group of the welding mechanism includes two welding knives / heating wires 43 and / or cutting dies 44. A through groove 46 for the cutter to pass through is provided between the two welding knives / heating wires 43 and / or cutting dies 44. The cutter drive 47 is used to drive the cutter 45 to move along the through groove 46 to cut the non-woven fabric.

[0076] More specifically, by providing the through groove 46 , the cutting track of the cutter 45 is ensured, and further, both sides after being cut by the cutter 45 are ensured to be two groups of non-woven fabrics that are welded.

[0077] like Figures 15-16The figure shows one specific embodiment of the welding and cutting mechanism 4 of the present invention. In this embodiment, there are two cutting dies 44, a through slot 46 is provided between the two cutting dies 44, and the cutter 45 passes through the through slot 46. At the same time, a groove for avoiding the cutter 45 is also provided on the welding knife 43, and the cutter drive 47 is a cylinder.

[0078] Furthermore, the first conveying mechanism 1 includes a first clamping conveying mechanism 11 and a pushing mechanism 12, the first clamping conveying mechanism 11 includes at least two oppositely arranged first conveying belts 13, the pushing mechanism 12 is arranged on one side of the first clamping conveying mechanism 11, and the second conveying mechanism 21 is arranged on the other side of the first clamping conveying mechanism 11, and the pushing mechanism includes a push plate 14 and a push plate drive 17 that drives the push plate to push the spring string from the first clamping conveying mechanism to the second conveying mechanism.

[0079] More specifically, the conveying direction of the first clamping and conveying mechanism 11 is perpendicular to the conveying direction of the second clamping and conveying mechanism 21. By setting the first clamping and conveying mechanism 11, it can be ensured that the bagged spring string can be conveyed to the specified position of the first clamping and conveying mechanism 11. At the same time, a push plate 14 is provided to push the bagged spring string, effectively ensuring that the bagged spring string can be pushed to the specified position for bonding.

[0080] Furthermore, the spacing between the two first conveyor belts 13 is adjustable, the push plate 14 includes an upper push plate 15 and a lower push plate 16, the upper push plate 15 and the lower push plate 16 are arranged opposite to each other and are in a toothed shape, and the spacing between the upper push plate 15 and the lower push plate 16 is adjustable.

[0081] like Fig.14 The figure shows one embodiment of the pushing mechanism of the present invention, wherein the spacing between the two first conveyor belts 13 is adjustable, and the spacing between the upper push plate 15 and the lower push plate 16 is adjustable, so that the first conveying mechanism 1 can convey pocket spring strings of different heights to the second conveying mechanism 2.

[0082] like Fig.14 As shown, the push plate drive 17 is a linear drive mechanism coordinated by a motor, a belt, etc.

[0083] Furthermore, the glue spraying mechanism 3 includes a glue spraying head 31 and a displacement mechanism 32 . The glue spraying mechanism 3 is provided with at least one glue spraying head 31 . The displacement mechanism 32 is used to drive the glue spraying head 31 to displace in a direction perpendicular to the conveying direction of the second conveying mechanism 2 .

[0084] like Fig.13 The figure shows one embodiment of the glue spraying mechanism 3 of the present invention, wherein the displacement mechanism 32 is a linear drive mechanism coordinated by a motor, a belt, and the like.

[0085] More specifically, by providing the displacement mechanism 32, it is ensured that the glue spray head 31 can be displaced in a direction perpendicular to the conveying direction of the second conveying mechanism 2, and further ensured that the glue spray head 31 can spray glue completely, which is beneficial to the quality of subsequent bonding.

[0086] Furthermore, it also includes an unwinding mechanism 5, and the two unwinding mechanisms 5 are respectively used for unwinding or rewinding two groups of non-woven fabrics.

[0087] More specifically, by providing an unwinding mechanism 5 that can unwind or rewind, two groups of nonwoven fabrics can be tensioned by the two unwinding mechanisms 5 .

[0088] It should be noted that, preferably, the unwinding mechanism 5 is an unwinding roller that can rotate forward and reverse.

[0089] Furthermore, when the two second conveyor belts 23 are relatively close to each other or move away from each other, the cloth-passing rollers 22 and the welding and cutting mechanisms 4 corresponding to the two second conveyor belts 23 are displaced synchronously.

[0090] More specifically, the cloth passing rollers 22 and the welding and cutting mechanism 4 corresponding to the two second conveyor belts 23 are displaced synchronously with the two Susou second conveyor belts 23, thereby ensuring that the distance between the welding and cutting mechanism 4 and the non-woven fabric remains unchanged, avoiding contact between the welding and cutting mechanism 4 and the non-woven fabric during the non-welding cutting process.
