[0055] At present, the efficiency of bed net combination has become a key factor restricting the production efficiency of bed net. In order to improve the efficiency of bed net combination, the invention patent CN109619902A proposes a manufacturing method of bed net, which envisages that single spring string is first combined into composite spring string, and then the composite spring string is combined into bed net. However, it is not clear how to realize this manufacturing process in the envisaged method.

[0056] Referring to Figure 1 and Figure 2 , according to the multi-stage bed net combination equipment provided by the present application, it comprises a feeding module 100, a spring string composite module 200 and a bed net generation module 300. The spring string composite module 200 is located downstream of the feeding module 100. The spring string composite module 200 comprises a first conveying line 210 and a second conveying line 220. The first conveying line 210 and the second conveying line 220 extend along a first direction. Two groups of first conveying lines 210 are respectively located on both sides of the second conveying line 220 in a second direction. The spring string composite module 200 further comprises a first driving member 231 and a first pushing member 232. The first pushing member 232 is located on the side of the first conveying line 210 away from the second conveying line 220 in the second direction. The first driving member 231 can drive the first pushing member 232 to move in the second direction, so as to push the spring string 910 from the first conveying line 210 to the second conveying line 220. The bed net generation module 300 is located downstream of the spring string composite module 200.

[0057] The feeding module 100 is used to provide the spring string 910, the spring string composite module 200 can combine at least two spring strings 910 from the feeding module 100 to form a composite spring string 920, and the bed net generation module 300 can combine the composite spring string 920 from the spring string composite module 200 in sequence to form the bed net 930.

[0058] The "downstream" is determined based on the conveying direction of the spring string 910, the first direction is the same as the conveying direction of the spring string 910 (that is, the tangent direction of each point on the conveying route), the second direction refers to the stacking direction when the spring string 910 is stacked into the bed net 930, that is, the thickness direction of the spring string 910, and the third direction refers to the width direction of the spring string 910. Figure 1 And Figure 2 In the embodiment, the first direction corresponds to the X direction, the second direction corresponds to the Y direction, and the third direction corresponds to the Z direction.

[0059] According to the multi-stage bed net combination device provided in the present application, by arranging the spring string composite module 200, the multi-stage bed net combination device can receive two or more spring strings 910 at a time, combine the spring strings 910 into a composite spring string 920 first, and then combine the composite spring string 920 into the bed net 930, thereby improving the combination efficiency of the bed net 930. The second conveying line 220 is arranged between the two first conveying lines 210, and the spring string 910 is pushed by the first pushing member 232, so that the combination of two spring strings 910 can be conveniently realized. Moreover, while the second conveying line 220 sends out the composite spring string 920 downstream, the feeding module 100 can provide new spring strings 910 to the first conveying line 210, so that the sending and receiving can be carried out in parallel, and the combination efficiency of the bed net is further improved.

[0060] It can be understood that "multi-stage" refers to two stages or more than two stages, Figure 1 The multi-stage bed net combination device with two stages is embodied, wherein the feeding module 100 to the second conveying line 220 is the first stage, and the second conveying line 220 to the bed net generation module 300 is the second stage, and at this time the multi-stage bed net combination device can receive two spring strings 910 at a time. On this basis, the spring string composite module 200 can be further expanded to increase the number of stages.

[0061] For example Figure 3 The multi-stage bed net combination device with three stages is embodied, and the first conveying line 210, the second conveying line 220 and the third conveying line 230 are arranged in sequence. Figure 3In some embodiments, the spring string composite module 200 further comprises a third conveying line 240 downstream of the second conveying line 220 and a fourth conveying line 250 between the two third conveying lines 240, the composite spring strings 920 on the second conveying line 220 pass through the third conveying lines 240 to the fourth conveying line 250, and are further combined into four-layer composite spring strings 920 on the fourth conveying line 250, and are sent to the bed net generating module 300 by the fourth conveying line 250. The multi-stage bed net combination device with three stages can receive four spring strings 910 at a time, thereby further improving the processing capacity of the multi-stage bed net combination device and improving the combination efficiency of the bed net 930.

[0062] In some embodiments, the feeding module comprises a feeding unit and a cutting unit, the feeding unit and the cutting unit are arranged in sequence along the first direction, the feeding unit comprises a plurality of feeding assemblies 110 arranged in the second direction, the feeding assemblies 110 are used to send out spring strings 910, and the cutting unit comprises a plurality of cutting assemblies 120 arranged in the second direction, the cutting assemblies 120 are used to cut the continuous spring strings 910 into spring strings 910 of a predetermined length.

[0063] One feeding assembly 110 is responsible for feeding one spring string 910 to the spring string composite module 200, and when the spring string 910 received by the spring string composite module 200 reaches a predetermined length, the cutting assembly 120 cuts off the spring string 910, completing the feeding of the spring string 910 once.

[0064] In some embodiments, at least one feeding assembly 110 is used in pairs with a group of first conveying lines 210.

[0065] “Feeding assembly 110 is used in pairs with first conveying line 210” means that this part of the feeding assembly 110 is responsible for feeding the spring string 910 to the paired first conveying line 210. For a better understanding, please refer to the embodiments of Figure 1 and Figure 4 In the embodiment of Figure 1 , one feeding assembly 110 is used in pairs with the first conveying line 210, so that the first conveying line 210 can only receive one specification of spring string 910, while in the embodiment of Figure 4 , two feeding assemblies 110 are used in pairs with the first conveying line 210, on the one hand, the two feeding assemblies 110 can be responsible for feeding two specifications of spring string 910 respectively, so that the multi-stage bed net combination device can produce more complex bed nets 930; on the other hand, the two feeding assemblies 110 can also be set to alternately feed the same specification of spring string 910, thereby improving the supply speed of the spring string 910, and further improving the combination efficiency of the bed net 930. The multi-stage bed net combination device can specifically determine the number of first feeding assemblies according to production needs.

[0066] It can be understood that in some cases, the spring string composite module 200 needs to send single spring strings 910 to the bed web generating module 300, such as a single layer of bed web 930 or a bed web 930 in which the specifications of the outermost spring strings 910 are different from those of the other spring strings 910. In these cases, if the single spring strings 910 are transported by being sequentially transported through the first conveying line 210 and the second conveying line 220, time will be wasted and the efficiency of assembling the bed web 930 will be reduced.

[0067] To this end, in some embodiments, at least one feeding assembly 110 is paired with the second conveying line 220. That is, a plurality of feeding assemblies 110 are respectively paired with the first conveying line 210 or the second conveying line 220, wherein a part of the feeding assemblies 110 are paired with the first conveying line 210, and another part of the feeding assemblies 110 are paired with the second conveying line 220.

[0068] “Feeding assemblies 110 are paired with the second conveying line 220” means that this part of the feeding assemblies 110 is responsible for supplying spring strings 910 to the corresponding second conveying line 220. Referring to the embodiment of Figure 5 , the feeding assemblies 110 directly transport the spring strings 910 to the second conveying line 220, thereby eliminating the process of pushing the spring strings 910 to the second conveying line 220 by the first pushing member 232, and improving the efficiency of assembling the bed web 930. The number of feeding assemblies 110 paired with the second conveying line 220 can be multiple, thereby allowing different specifications of single spring strings 910 to be provided.

[0069] On this basis, it can be recognized that in some embodiments, the number of feeding assemblies 110 of the multi-stage bed web assembling device can be greater than the upper limit of the spring strings 910 that can be received by the spring string composite module 200 at one time. To this end, in some embodiments, the cutting assembly 120 can move in the second direction to switch the pairing of the cutting assembly 120 with different feeding assemblies 110.

[0070] “Cutting assembly 120 is paired with feeding assembly 110” means that the cutting assembly 120 is responsible for cutting the spring strings 910 sent out by the currently paired feeding assembly 110. At the same time, in other words, the cutting assembly 120 can move in the second direction, so that the cutting assembly 120 can also switch the pairing with the first conveying line 210 or the second conveying line 220. When the feeding assembly 110 needs to send the spring strings 910 to the first conveying line 210, the cutting assembly 120 is paired with the first conveying line 210, and when the feeding assembly 110 needs to send the spring strings 910 to the second conveying line 220, the cutting assembly 120 is paired with the second conveying line 220.

[0071] The ability to swap and pair cutting assemblies 120 allows the multi-stage bed net assembly to reduce the number of cutting assemblies 120. Simply setting the number of cutting assemblies 120 equal to the upper limit of the spring strings 910 that the spring string assembly module 200 can simultaneously receive can meet the spring string 910 cutting requirements. For example, a two-stage multi-stage bed net assembly requires at least two cutting assemblies 120, while a three-stage multi-stage bed net assembly requires at least four cutting assemblies 120. Reducing the number of cutting assemblies 120 not only reduces the production cost of the multi-stage bed net assembly, but also frees up space, simplifies the cutting unit structure, and facilitates the installation of cutting assemblies 120 and other components.

[0072] In some embodiments, the cutting assembly 120 includes a welding knife 121, a welding knife holder 122, a cutter 123, and a first mounting plate 124. The two first mounting plates 124 are spaced apart in the second direction. The welding knife 121 is mounted on one of the first mounting plates 124, and the welding knife holder 122 and the cutter 123 are mounted on the other first mounting plate 124. A continuous spring string 910 passes between the two first mounting plates 124. The two first mounting plates 124 approach each other, allowing the cutter 123 to cut the spring string 910. The welding knife 121 and the welding knife holder 122 weld the cut portion to prevent accidental openings in the fabric at that portion.

[0073] In some embodiments, the cutting unit includes a connecting rod 138, which extends along the second direction. The first mounting plates 124 located on the same side of each cutting component 120 are connected by a group of connecting rods 138, and the first mounting plates 124 located on the other side of each cutting component 120 are connected by another group of connecting rods 138.

[0074] by Figure 6 For example, in Figure 6 In the embodiment, the Y direction (i.e., the second direction) is defined as the left-right direction. The cutting unit includes two cutting assemblies 120. The first mounting plates 124 on the left sides of the two cutting assemblies 120 are connected together, and the first mounting plates 124 on the right sides of the two cutting assemblies 120 are connected together. Thus, a linkage relationship is established between the first mounting plates 124 of the two cutting assemblies 120, allowing the two cutting assemblies 120 to synchronously execute the action of approaching each other, thereby improving the consistency of the cutting process.

[0075] And in some embodiments, the cutting unit includes an elastic member 137, a connecting rod 138 is passed through the first mounting plate 124, the connecting rod 138 includes a limit end, the first mounting plate 124 is located between the two limit ends, and the elastic member 137 is connected between the connecting rod 138 and the first mounting plate 124 to allow the first mounting plate 124 to float in the second direction.

[0076] That is, when the first mounting plates 124 are close to each other, the spring string 910 is clamped by the welding blade 121 and the welding blade seat 122, if the clamping force is too large, the elastic member 137 will be deformed, so that the two first mounting plates 124 are slightly away from each other, and compensation is generated, so that the clamping force is reduced to the set size. The elastic member 137 can be a compression spring as shown in the figure, which pushes the first mounting plate 124 to one of the limiting ends, or can also be a tension spring, a gas spring, etc. Figure 6

[0077] The first mounting plate 124 can be driven by the second driving member 133. For example, in some embodiments, the cutting unit includes a first mounting frame and the second driving member 133, the second driving member 133 is connected between the first mounting frame and the first mounting plate 124, and the second driving member 133 can drive the two first mounting plates 124 of the same cutting assembly 120 to move close to or away from each other. Referring to Figure 6 , the first mounting frame can include the second mounting plate 134 and the first guide rod 136, the two second mounting plates 134 are arranged opposite to each other in the second direction, the cutting assembly 120 is located between the two second mounting plates 134, the first guide rod 136 is arranged between the two second mounting plates 134, and the first mounting plate 124 is sleeved on the first guide rod 136, so as to realize the installation of the cutting assembly 120.

[0078] Returning to the cutting assembly 120, in some embodiments, the welding blade seat 122 can be composed of two parts arranged in the first direction, the two parts of the welding blade seat 122 form a first avoiding slot extending in the third direction, the welding blade 121 forms a second avoiding slot extending in the third direction, and the cutting assembly 120 further includes the third driving member 125, which can drive the cutting knife 123 to move in the first avoiding slot and the second avoiding slot in the third direction to cut the spring string 910.

[0079] The cutting assembly 120 can be switched by the fourth driving member 132. For example, in some embodiments, the cutting unit includes a second mounting frame and the fourth driving member 132, the fourth driving member 132 is connected between the second mounting frame and the first mounting frame, and the fourth driving member 132 can drive the first mounting frame to move in the second direction. Referring to Figure 6 , the second mounting frame can include the third mounting plate 135 and the second guide rod 131, the two third mounting plates 135 are arranged opposite to each other in the second direction, the second guide rod 131 is arranged between the two third mounting plates 135, and the second mounting plate 134 is sleeved on the second guide rod 131, so as to realize the installation of the first mounting frame. This makes the fourth driving member 132 able to drive two or more cutting assemblies 120 to move synchronously, which can reduce the number of fourth driving members 132 and simplify the structure of the cutting unit, and also makes the synchronization of each cutting assembly 120 higher. ​

[0080] In some embodiments, the feeding assembly 110 is capable of moving in the second direction to switch pairing with the first conveying line 210 or the second conveying line 220. For example, referring to Figure 7 In some embodiments, the feeding unit has four feeding assemblies 110, which are divided into two groups, and the two groups of feeding assemblies 110 can be alternately paired with the first conveying line 210 when feeding is needed for the first conveying line 210, and the two groups of feeding assemblies 110 can also be alternately paired with the second conveying line 220 when feeding is needed for the second conveying line 220. In this way, it also helps to improve the supply speed of the spring string 910. In some embodiments, the multi-stage bed net combination device is capable of moving both the cutting assembly and the feeding assembly 110 in the second direction.

[0081] By comparing Figure 4 and Figure 7 embodiments, it can be realized that the feeding assembly 110 is moved to alternately feed the spring string composite module 200, which helps to reduce the size of the spring string composite module 200 in the second direction. However, on the other hand, since the feeding assembly 110 needs to be connected with the upstream pocketed spring production machine, the movement of the feeding assembly 110 may cause problems in the conveying of the spring string 910 between the pocketed spring production machine and the multi-stage bed net combination device, and the mass of the feeding assembly 110 is generally heavier than that of the cutting assembly 120, so the inertia is larger, and it is more difficult to ensure the control accuracy and switching speed of the movement of the feeding assembly 110. In addition, the movement of the feeding assembly 110 cannot reduce the number of feeding assemblies 110 and simplify the structure of the multi-stage bed net combination device.

[0082] Referring to Figure 8 In some embodiments, the feeding assembly 110 includes a first pressing member 111 and a second pressing member 112, the two groups of first pressing members 111 are oppositely arranged in the second direction, and the first pressing members 111 can approach each other to clamp the spring string 910 in the second direction, the two groups of second pressing members 112 are oppositely arranged in the third direction, and the second pressing members 112 can approach each other to clamp the spring string 910 in the third direction, and the feeding unit further includes a fifth driving member (not shown in the figure), which is used to drive the feeding assembly 110 to move in the first direction so that the spring string 910 passes through the cutting assembly 120.

[0083] In combination with referring to Figure 7 and Figure 8 , the feeding assembly 110 clamps the spring string 910 and moves in the first direction, so that the end of the spring string 910 can pass through the cutting assembly 120 to the downstream, so that the spring string composite module 200 receives the spring string 910. The first pressing member 111 and the second pressing member 112 jointly act to accurately position the spring string 910.

[0084] In some embodiments, the feeding module comprises a transfer unit between the cutting unit and the spring-in-string composite module, which is used to transfer the spring-in-string 910. The transfer unit is suitable for the case that the spring-in-string composite module 200 is difficult to directly receive the spring-in-string 910.

[0085] For example, in the embodiment of Figure 7 , since the feeding assembly 110 directly clamps the end of the spring-in-string 910, and the second pressing member 112 is located on both sides of the spring-in-string 910 in the third direction, the feeding assembly 110 extending into the spring-in-string composite module 200 will cause the second pressing member 112 to interfere, so the transfer unit is added for transfer. Referring to Figure 7 , in some embodiments, the transfer unit comprises a plurality of transfer assemblies 140, which are respectively paired with the first conveying line 210 or the second conveying line 220 downstream. The transfer assembly 140 comprises a third conveying belt 141, and two groups of third conveying belts 141 are oppositely arranged in the third direction, and two third conveying belts 141 in the same group are arranged at intervals in the second direction. The second pressing member 112 can extend between the two third conveying belts 141, and the second pressing member 112 will not interfere when it is opened, thereby ensuring the conveying of the spring-in-string 910 between the feeding assembly 110 and the transfer assembly 140. In addition, the conveying speed of the third conveying belt 141 can be higher than the speed of the first conveying line 210 and the second conveying line 220, which makes the spring individuals of the spring-in-string 910 abut against each other under the action of the speed difference during the transfer process, thereby improving the stability of the bed net assembly.

[0086] Or in some other embodiments, the distance between the cutting unit and the spring-in-string composite module 200 is far or the conveying route has a bend, and the transfer unit can also be used for transfer.

[0087] In some embodiments, the multi-stage bed net assembly device comprises a first detector for detecting the spring individuals in the spring-in-string 910 received by the spring-in-string composite module 200, so as to control the interval of the spring individuals and the conveying of the spring-in-string 910. Specifically, the first detector can detect the spring individuals passing through the detection position, so as to count the spring individuals and calculate the interval between adjacent spring individuals, and the relative speed of the spring-in-string composite module 200 and the feeding module 100 is adjusted according to the current interval, so as to control the interval, and when the count reaches a set value, it can be judged that the conveying of the spring-in-string 910 has been completed.

[0088] The relative speed of the spring string composite module 200 and the feeding module 100 refers to the difference between the speed of the spring string composite module 200 receiving the spring string 910 and the speed of the feeding module 100 feeding the spring string 910. In the embodiment with the transfer unit, the relative speed can be adjusted by adjusting the speed of the third conveying belt 141.

[0089] Similarly, in some embodiments, the multi-stage bed net combination device comprises a second detector for detecting the spring individuals in the spring string 910 or the composite spring string 920 received by the bed net generating module 300, so as to control the spacing of the spring individuals and the conveying of the spring string 910 or the composite spring string 920.

[0090] The first detector and the second detector can adopt photoelectric sensors or magnetoelectric sensors, etc. The first detector and the second detector are directed towards the conveying route of the spring string 910 or the composite spring string 920, for example, the first detector can be arranged on one side of the transfer assembly 140, one side of the first conveying line 210, one side of the second conveying line 220, between the feeding module 100 and the spring string composite module 200, etc.

[0091] Referring to Figure 9 and Figure 10 In some embodiments, the first conveying line 210 comprises first conveying belts 211, two groups of the first conveying belts 211 are oppositely arranged in the third direction to position the spring string 910 in the third direction, and the first conveying belts 211 can approach or move away from each other. “Positioning” refers to that the two groups of the first conveying belts 211 are respectively in contact with the two ends of the spring string 910, so as to define the position of the spring string 910 in the third direction, improve the consistency of the spring strings 910 in each layer of the bed net 930, and the first conveying belts 211 can approach or move away from each other to adapt to spring strings 910 of different specifications. Similarly, in some embodiments, the second conveying line 220 comprises second conveying belts 221, two groups of the second conveying belts 221 are oppositely arranged in the third direction to position the spring string 910 in the third direction, and the second conveying belts 221 can approach or move away from each other.

[0092] For example, referring to Figure 10 In some embodiments, the spring string composite module 200 can comprise mounting frames 233, a screw sliding block mechanism 234 and a sixth driving member 235, two mounting frames 233 are oppositely arranged in the third direction, two groups of the first conveying belts 211 and two groups of the second conveying belts 221 are respectively mounted on the two mounting frames 233, the screw sliding block mechanism 234 is connected between the two mounting frames 233, a screw extends in the third direction, the sixth driving member 235 is mounted on one of the mounting frames 233, and the sixth driving member 235 is drivingly connected with the screw sliding block mechanism 234 to drive the two mounting frames 233 to approach or move away from each other.

[0093] The spring string composite module 200 can combine the spring strings 910 by means of adhesion or welding. Referring to Figure 9 and Figure 10 In some embodiments, the spring string composite module 200 further comprises a first glue spraying member 236, which is located between the first conveying line 210 and the second conveying line 240 in the second direction and is located on the side of the first conveying line 210 close to the feeding module 100 in the first direction. The nozzle of the first glue spraying member 236 is flush with the spring strings 910 in the third direction and faces the first conveying line 210. When the spring strings 910 enter the first conveying line 210, the first glue spraying member 236 sprays glue on the surface of the spring strings 910, and then the two spring strings 910 are adhered together under the action of the first pushing member 232.

[0094] In some other embodiments, a welding knife and a welding knife seat can also be arranged on the two groups of first pushing members 232 respectively, so as to weld and combine the two spring strings 910 on the second conveying line 220.

[0095] Referring to Figure 11 and Figure 12 In some embodiments, the bed net generating module 300 comprises a fifth conveying line 310, a receiving platform 320 and a second pushing member 331. The fifth conveying line 310 is located downstream of the second conveying line 220 and extends in the first direction. The receiving platform 320 is located on one side of the fifth conveying line 310 in the second direction, and the second pushing member 331 is located on the other side of the fifth conveying line 310 in the second direction. The fifth conveying line 310 receives the composite spring strings 920, and the second pushing member 331 moves in the second direction to push the composite spring strings 920 to the receiving platform 320, thereby forming the bed net 930.

[0096] It can be understood that Figure 11 and Figure 12 Only one embodiment of the bed net generating module 300 is shown. In some other embodiments, the bed net generating module 300 can also not comprise the fifth conveying line 310. In this case, the material transfer between the spring string composite module 200 and the bed net generating module 300 can be achieved by the following means: the second conveying line 220 extends in the first direction to between the second pushing member 331 and the receiving platform 320, and the second pushing member 331 directly pushes the composite spring strings 920 on the second conveying line 220 to the receiving platform 320. In other words, the second conveying line 220 replaces the fifth conveying line 310 to complete the function of transferring the composite spring strings 920 to the receiving platform 320.

[0097] In some embodiments, the bed net generating module further comprises a second glue spraying member 332, a baffle 333, a seventh driving member, and an eighth driving member 334. The baffle 333 extends along the first direction, and is located between the fifth conveying line 310 and the receiving platform 320. The two baffles 333 are oppositely arranged in the third direction. The second glue spraying member 332 is located between the fifth conveying line 310 and the receiving platform 320. The nozzle of the second glue spraying member 332 faces the fifth conveying line 310 or the receiving platform 320. The seventh driving member can drive the second glue spraying member 332 to move along the first direction. The eighth driving member 334 can drive the baffle 333 to flip to avoid the second glue spraying member 332.

[0098] With reference to Figure 13 The application also provides a second multi-stage bed net combination device. Compared with the multi-stage bed net combination device described above, Figure 1 And Figure 13 It can be recognized that the second multi-stage bed net combination device is different from the multi-stage bed net combination device described above in that the first conveying line 210 is located on one side of the second conveying line 220 in the second direction. The spring string combination module 200 further comprises a first driving member 231, a blocking member 237, and a first pushing member 232. The blocking member 237 is located on the side of the second conveying line 220 away from the first conveying line 210 in the second direction. The first pushing member 232 is located on the side of the first conveying line 210 away from the second conveying line 220 in the second direction.

[0099] In such embodiments, when the combination spring string 920 is combined, the first conveying line 210 and the second conveying line 220 respectively receive a spring string 910. Then, the first pushing member 232 pushes the spring string 910 on the first conveying line 210 to the second conveying line 220, so that the spring strings 910 are combined together.

[0100] In such embodiments, in order to avoid conflicts or interference, the second conveying line 220 sending out the combination spring string 920 and the second conveying line 220 receiving the spring string 910 generally need to be performed in sequence.

[0101] With reference to Figure 14 The application also provides a bed net combination method. The bed net combination method uses the multi-stage bed net combination device provided by the application.

[0102] The bed net combination method comprises the following steps:

[0103] Step S211: In response to the demand of the bed net generating module 300 for the combination spring string 920, the feeding module 100 feeds at least two spring strings 910 to the spring string combination module 200.

[0104] Step S212: The spring string combination module 200 combines the at least two spring strings 910 into a combination spring string 920.

[0105] Step S213: the spring string composite module 200 supplies the bed net generation module 300 with the composite spring string 920;

[0106] Step S221: in response to the demand of the single spring string 910 by the bed net generation module 300, the feeding module 100 supplies the spring string composite module 200 with the single spring string 910;

[0107] Step S222: the spring string composite module 200 supplies the bed net generation module 300 with the single spring string 910.

[0108] Referring to Figure 14 According to some embodiments of the present application, the bed net assembly method further comprises:

[0109] Step S100: determining the next material required by the bed net generation module 300;

[0110] Step S300: the bed net generation module 300 sequentially assembles the received materials.

[0111] The bed net assembly method repeats the above steps until the bed net 930 of the required specification is formed.

[0112] In some embodiments, in step S211, the feeding assembly 110 supplies the two first conveying lines 210 with the spring strings 910; in step S212, the first pushing member 232 pushes the two spring strings 910 to the second conveying line 220, and the two spring strings 910 are combined to form the composite spring string 920 on the second conveying line 220; in step S213, the second conveying line 220 sends out the composite spring string 920. At this time, while the second conveying line 220 sends out the composite spring string 920, the feeding of the new spring string 910 to the first conveying line 210 can be started.

[0113] In some embodiments, in step S221, the feeding assembly 110 supplies the second conveying line 220 with the spring string 910.

[0114] In some embodiments, the relative speed of the feeding module 100 and the spring string composite module 200 is controlled to adjust the spacing of the individual springs in the spring string 910 received by the spring string composite module 200. Specifically, as described in the multi-stage bed net assembly device embodiment, the spacing information of the individual springs can be obtained by the first detector, and the relative speed can be changed by adjusting the speed of the first conveying belt 211, the second conveying belt 221, and the third conveying belt 141.

[0115] Similarly, the pitch of each spring individual in the spring string 910 or the composite spring string 920 received by the bed net generating module 300 can also be adjusted by controlling the relative speed of the spring string composite module 200 and the bed net generating module 300. Specifically, the pitch information of the spring individual can be obtained by the second detector, and the relative speed of the second conveying belt 221 and the fifth conveying line 310 can be adjusted to achieve the adjustment.
