Description

Technical Field

[0001] The present application relates to the technical field of bed net production equipment, and in particular to a bed net bonding device and a bed net bonding method. Background Art

[0002] The bed net bonding equipment is used to bond multiple spring strings in sequence to form a bed net. Usually, the bed net bonding equipment needs to be equipped with a loading assembly, which is used to lay the spring strings in place. The bed net bonding equipment is usually also equipped with a spraying assembly to spray glue on the spring strings, and the spring strings can be bonded to each other after spraying glue.

[0003] In the prior art, bed net bonding equipment has a complex structure. For example, the location of the glue spraying assembly requires a reversible avoidance device. During loading (laying the spring string), the avoidance device blocks the glue spraying assembly from the loading space to prevent interference between the glue spraying assembly and the loading assembly (or spring string). After loading, the avoidance device allows the glue spraying assembly to approach the spring string and spray glue on the surface of the spring string. This glue spraying method results in complex glue spraying operations and equipment structure. Summary of the Invention

[0060] See also Figures 1 to 4 In the first aspect of the present application, a bed net bonding device 1000 is provided, comprising a feeding mechanism 100, a combination platform 200, a pushing mechanism 300 and a glue spraying assembly 400. The feeding mechanism 100 is used to provide a spring string 2000, and the combination platform 200 is used to move the spring string along the second direction (such as Figure 1 The y direction shown in the figure) is arranged on the first side of the feeding mechanism 100, the assembly platform 200 is used to hold the bed net 2100 after bonding, and the pushing mechanism 300 is arranged on the second side of the feeding mechanism 100 along the second direction. The pushing mechanism 300 is used to push the spring string 2000 from the feeding mechanism 100 to the assembly platform 200. The glue spraying assembly 400 is arranged between the feeding mechanism 100 and the assembly platform 200, and the glue spraying assembly 400 includes a glue gun 410 and a ring assembly 420; the glue gun 410 is connected to the ring assembly 420, and the glue gun 410 is arranged along the first direction (as shown in the figure) and the y direction (as shown in the figure) Figure 1 The annular assembly 420 reciprocates in the x direction shown in the figure and is used to spray glue to the bed net 2100 or the spring string 2000. The annular assembly 420 moves synchronously with the glue gun 410. The annular assembly 420 includes at least one straight section 421. When the glue gun 410 moves, the straight section 421 is connected to the gap between the feeding mechanism 100 and the combination platform 200, so that the spring string 2000 has a smooth transition when it is pushed from the feeding mechanism 100 to the combination platform 200.

[0061] In the present application, by setting up the annular component 420 and setting the glue gun 410 on the annular component 420, the annular component 420 and the glue gun 410 can move synchronously, that is, when one of the annular component 420 or the glue gun 410 is driven, the other can move synchronously. On the one hand, after the glue gun 410 moves along the first direction x and sprays glue on the spring string 2000 or the bed net 2100, the glue gun 410 is located on one side of the spring string 2000 along the first direction x to prevent the glue gun 410 from blocking the push of the spring string 2000. At the same time, the annular component 420 moves synchronously with the glue gun 410. The straight section 421 of the annular component 420 constitutes a part of the moving path of the spring string 2000. Therefore, the annular component 420 will not interfere with the glue gun 410, the spring string 2000, and the feeding mechanism 100, thereby solving the problem of mutual interference between the glue spraying component 400 and the feeding mechanism 100. Therefore, there is no need to set an additional avoidance structure or avoidance action for the glue spraying component 400, thereby simplifying the structural design of the glue spraying component 400. On the other hand, the annular assembly 420 can fill the gap between the feed mechanism 100 and the assembly platform 200. The straight section 421 of the annular assembly 420 can form part of the passage for the spring string 2000 to enter the assembly platform 200 from the feed mechanism 100. This eliminates the need for additional mechanisms to fill the gap between the feed mechanism 100 and the assembly platform 200, further simplifying the structure of the glue spraying assembly 400. This reduces the number of components in the bed net 2100 assembly device, simplifies the structure of the bed net 2100 assembly device, and makes the overall structure more compact. During this process, the annular assembly 420 can ensure a smooth transition when the spring string 2000 is pushed from the feed mechanism 100 to the assembly platform 200, thereby improving the stability of the spring string 2000 during movement. Thus, configuring the glue spraying assembly 400 as an annular assembly 420 not only satisfies the requirement that the glue spraying assembly 400 avoid the spring string 2000 during the pushing process, but also achieves the effect of filling the gap and improving the stability of the spring string 2000 during movement.

[0062] See also Figure 3 It is understood that a portion of the annular assembly 420 forms a straight section 421, and the portion other than the straight section 421 is disposed in an area outside the gap between the feeding mechanism 100 and the assembly platform 200. During the annular movement of the annular assembly 420, the straight section 421 exhibits an effect of movement along the first direction x. Therefore, the movement trajectory of the straight section 421 is the same as that of the glue gun 410. By utilizing the annular structure of the annular assembly 420 connected end to end, the glue gun 410 reciprocates along the first direction x (e.g., Figure 3The annular assembly 420 always has a portion as a straight section 421 connected to the gap between the feeding mechanism 100 and the assembly platform 200, so that when the glue gun 410 moves to any position along the first direction x, the gap between the feeding mechanism 100 and the assembly platform 200 is always filled with a straight section 421, thereby ensuring that the spring string 2000 can smoothly transition from the feeding mechanism 100 to the assembly platform 200.

[0063] In some embodiments, the annular assembly 420 is provided with a notch 422, and the glue gun 410 is disposed in the notch 422 of the annular assembly 420. The annular assembly 420 moves in a circular direction to synchronize with the movement of the glue gun 410 in the first direction x. By providing the notch 422 in the annular assembly 420, the glue gun 410 can be disposed in the notch 422, thereby achieving mutual avoidance between the glue gun 410 and the annular assembly 420, thereby preventing interference between the two.

[0064] Optionally, the glue gun 410 can be provided with multiple or multiple groups of nozzles 411. In some examples, such as Figure 4 As shown, multiple groups of nozzles 411 are arranged in opposite directions along the second direction y. One group of nozzles 411 is used to spray glue onto the bed net 2100 located on the assembly platform 200, while another group of nozzles 411 is used to spray glue onto the spring string 2000 located in the feed mechanism 100. The glue gun 410 moves from one end of the spring string 2000 to the other along the first direction x, enabling simultaneous glue spraying on both the spring string 2000 and the bed net 2100, facilitating adhesion of the spring string 2000 to the bed net 2100. Of course, in other examples, the nozzles 411 can also be arranged unilaterally, specifically for spraying glue only onto either the spring string 2000 or the bed net 2100. In other examples, the multiple nozzles 411 can be arranged along the third direction z, with the spring's axial direction parallel to the third direction z. Simultaneous glue spraying by the multiple nozzles 411 allows for multi-point glue spraying along the spring's axial direction, improving glue spraying efficiency and effectiveness.

[0065] For example, see Figure 4The pushing mechanism 300 may include a push rod 310, a push plate, and other structures. The push rod 310 may be formed by the output end of a structure such as a motor or cylinder, or a rod may be provided connected to the output end of the motor. The push rod 310 is extended and retracted along the second direction y to push the spring string 2000 from the feeding mechanism 100 to the assembly platform 200, thereby achieving mutual adhesion between the spring string 2000 and the bed net 2100. The push plate may be provided at the end of the push rod 310 that contacts the spring string 2000 and may extend along the first direction x. This increases the contact area between the push rod 310 and the spring string 2000, ensuring smoother movement of the spring string 2000 during pushing. The push rod 310 can also provide support for the adhesion of the spring string 2000 and the bed net 2100. That is, when the spring string 2000 contacts the bed net 2100, the push rod 310 applies an extrusion force to the spring string 2000 along the second direction y, so that the spring string 2000 and the bed net 2100 are better bonded under the action of the extrusion force.

[0066] In some embodiments, the glue spraying assembly 400 further includes a first driving member 440, which is used to drive the glue gun 410 to reciprocate and simultaneously drive the annular assembly 420 to move. When the glue gun 410 moves along the first direction x to either end of the assembly platform 200, the annular assembly 420 fills the gap between the feed mechanism 100 and the assembly platform 200 along the first direction x. The driving action of the first driving member 440 enables the movement of the annular assembly 420 and the glue gun 410, meeting the glue gun 410's need to spray glue on the spring string 2000 and the bed net 2100, and meeting the need for the annular assembly 420 to bridge the gap between the feed mechanism 100 and the assembly platform 200. By using the annular component 420 to fill the gap along the first direction x, it can be ensured that any spring in the spring string 2000 can be supported by the annular component 420 during the process of moving from the feeding mechanism 100 to the combination platform 200, thereby preventing the spring from being stuck in the gap between the feeding mechanism and the combination platform 200, and further improving the reliability of the pushing process of the spring string 2000.

[0067] Exemplarily, the first driving member 440 can be a motor, a cylinder, etc. Taking the motor as an example, the motor power is output to the annular component 420. While driving the annular component 420 to move in a circular direction, the annular component 420 can drive the glue gun 410 to move along the first direction x. Alternatively, the motor power is output to the glue gun 410. While driving the glue gun 410 to move, the glue gun 410 drives the annular component 420 to move in a circular direction. Optionally, in order to improve the stability of the annular component 420 during movement, the glue spraying component 400 can also be provided with a guide rail 5161 to provide guidance for the movement of the annular component 420. The output end of the motor can be directly connected to the annular component 420 or the glue gun 410, or it can indirectly drive the annular component 420 or the glue gun 410 to move through other transmission parts such as belts.

[0068] In some embodiments, the ring plane formed by the ring assembly 420 is perpendicular to the second direction y. This allows the ring assembly 420, excluding the straight section 421, to fit within the space between the feed mechanism 100 and the assembly platform 200, making the entire bed net bonding apparatus 1000 more compact. Of course, in other examples, the ring plane formed by the ring assembly 420 can also be perpendicular to the third direction z.

[0069] In some embodiments, the ring assembly 420 includes at least one of a chain plate, a conveyor chain, and a conveyor belt. Figure 3 For example, the annular assembly 420 is formed by splicing a plurality of chain plates in sequence along the annular direction. The plurality of chain plates are engaged with each other to form a continuous chain structure. Adjacent chain plates can rotate with each other. Adjacent chain plates can be arranged coplanarly to form a straight section 421. Adjacent chain plates can also form a certain angle to enclose and form an annular structure. Each chain plate unit has a certain supporting area. Therefore, after the chain plates are connected to each other, a straight section 421 with a certain width can be formed to achieve the connection of the gap between the feeding mechanism 100 and the assembly platform 200. Of course, in other examples, the annular assembly 420 can also be a structure such as a conveyor chain, a conveyor belt (such as a belt), or a combination of any two or more of the chain plates, the conveyor chain, and the conveyor belt.

[0070] Optionally, to achieve smooth circumferential movement of the annular assembly 420, the glue spraying assembly 400 may further include a plurality of steering rollers 450, which are disposed at least on the inner side of the annular assembly 420. The steering rollers 450 are used to support and provide tension to the annular assembly 420, so that the annular assembly 420 can be supported to form an annular plane, and the annular assembly 420 can perform smooth circumferential movement under the support of the steering rollers 450. Optionally, one of the steering rollers 450 may also serve as the first driving member 440 to provide power for the circumferential movement of the annular assembly 420. For example, a rotary motor may be used to drive one of the steering rollers 450, and the rotation of the steering roller 450 drives the annular assembly 420 to rotate in the circumferential direction, thereby causing the glue gun 410 to move along with the annular assembly 420.

[0071] In some embodiments, see Figure 2The feeding mechanism 100 includes first conveying members 110 arranged in pairs along a third direction z. The two first conveying members 110 are used to clamp the spring string 2000 and convey the spring string 2000 along a first direction x. The two first conveying members 110 form a first feeding channel 111, and the spacing between the first conveying members 110 is adjustable. The combined platform 200 includes third conveying members 210 arranged in pairs along a third direction z. The two third conveying members 210 are used to clamp the bed net 2100 and convey the bed net 2100 along a second direction y. The two third conveying members 210 form a bed net channel 211, which is connected to the first feeding channel 111 along the second direction y. By using a pair of first conveying members 110 to clamp the spring string 2000 along the third direction z, the spring string 2000 can be stabilized in the axial direction of the spring, preventing the spring string 2000 from bouncing during conveyance. Similarly, the two third conveying members 210, arranged in pairs along the third direction z, also stabilize the bed net 2100 and the spring string 2000 bonded to it. The bed net channel 211 is connected to the first feed channel 111 along the second direction y. This allows the spring string 2000 to be pushed into the bed net channel 211 by the pushing mechanism 300 along the second direction y within the first feed channel 111, where it is bonded to the bed net 2100 within the channel 211. The spring string 2000 is arranged and loaded along the first direction x and bonded to the bed net 2100 along the second direction y. This arrangement prevents interference between the loading and bonding operations of the spring string 2000, improving the independence and operational reliability of the loading and bonding processes of the spring string 2000.

[0072] In some embodiments, see Figure 4 A connecting channel 430 is provided in the gap between the bed net channel 211 and the first feed channel 111. On one side of the connecting channel 430, in the third direction z, is a straight section 421 of the annular assembly 420, and on the other side, a transition plate 431 is provided. Using the connecting channel 430 to fill the gap between the bed net channel 211 and the first feed channel 111 ensures a smooth transition of the springs from the first feed channel 111 into the bed net channel 211. One side of the connecting channel 430 is formed by the straight section 421 of the annular assembly 420, which reduces the space occupied by the adhesive spraying assembly 400. On the other side of the connecting channel 430, a transition plate 431 is provided. The transition plate 431 and the straight section 421 of the annular assembly 420 can clamp the spring string 2000 along the third direction z, preventing the spring string 2000 from bouncing or deforming during movement and improving the stability of the spring string 2000 during movement.

[0073] Optionally, Figure 4 For example, the third direction z may be the vertical direction, that is, the straight section 421 of the annular assembly 420 and the transition plate 431 are distributed vertically. Figure 4 In the example of , the transition plate 431 is disposed above the annular assembly 420. Of course, in other examples, the third direction z may not be limited to the vertical direction, and the third direction z may also be the horizontal direction.

[0074] In some embodiments, please refer to Figure 2 The feeding mechanism 100 further includes a pair of second conveying members 120 arranged along the third direction z. The second conveying members 120 are used to clamp the spring string 2000 along its axial direction. The two second conveying members 120 form a second feeding channel 121. The second conveying members 120 are arranged at the upstream end of the first conveying member 110 along the first direction x. The second feeding channel 121 is connected to the first feeding channel 111. The conveying speed difference between the second conveying members 120 and the first conveying member 110 can be adjusted to adjust the spacing between adjacent springs in the spring string 2000. Because the spring string 2000 is formed by wrapping multiple springs individually with fabric, that is, adjacent springs in the spring string 2000 are connected by the fabric, so adjacent springs can move relative to each other. Therefore, by utilizing the difference in conveying speed between the second conveying member 120 and the first conveying member 110, the speed difference can adjust the distance between two adjacent springs (that is, the distance between adjacent springs in the first direction x), and the spring string 2000 can be adjusted to the target distance when loading. Subsequently, the spring string 2000 is pushed to the combined platform 200 in the first feeding channel 111. At this time, the spring string 2000 can be directly bonded to the bed net 2100 without the need to adjust the spring spacing again, thereby improving the operational efficiency of bonding the bed net 2100.

[0075] In some embodiments, the feeding mechanism 100 further includes a first transmission member 130 and a second transmission member 140. The first transmission member 130 drives the paired first conveying members 110 for synchronous conveyance, while the second transmission member 140 drives the paired second conveying members 120 for synchronous conveyance. The first transmission member 130 enables synchronous movement of the two first conveying members 110, ensuring smooth transportation of the spring string 2000 within the first conveying channel. Similarly, the second transmission member 140 enables synchronous movement of the two second conveying members 120, ensuring smooth transportation of the spring string 2000 within the second conveying channel.

[0076] For example, the first transmission member 130 can be a transmission rod with transmission gears disposed at both ends of the transmission rod, and the two first conveying members 110 are driven by the two transmission gears, respectively. The configuration of the second transmission member 140 can refer to the first transmission member 130. It is understood that the transmission speed of the second transmission member 140 can be set to be different from that of the first transmission member 130, thereby creating a speed difference between the first conveying member 110 and the second conveying member 120, so that adjacent springs in the spring string are brought closer to each other during the conveying process.

[0077] For example, the first conveying member 110 and the second conveying member 120 may be structures such as conveyor belts and conveyor chains.

[0078] In some embodiments, please combine Figure 4 and Figure 5 The combined platform 200 includes a second driving member 220, a supporting module 230, and a movable module 240 spaced apart along a third direction z. A bed net channel 211 is formed between the supporting module 230 and the movable module 240. The bed net channel 211 is used to transport the bed net 2100 along the second direction y. The driving member drives the movable module 240 to move along the third direction z to adjust the height of the bed net channel 211. The first and second conveying members 110 and 120, located on the same side of the movable module 240 along the third direction z, are connected to the movable module 240 and move along with it. The movable module 240 moves relative to the supporting module 230, allowing the height of the bed net channel 211 to be adjusted to accommodate spring strings 2000 of varying heights. The supporting module 230 and the movable module 240 both clamp the bed net 2100, preventing the spring string 2000 from bouncing or deforming. In this way, the spring string 2000 is always held axially at both ends during the loading, pushing, and gluing processes of the spring string 2000 into the bed net channel 211. When adjusting the movable module 240, the movable module 240 simultaneously drives the first and second conveying members 110, 120 on the same side to move, enabling synchronous adjustment of the heights of the first and second conveying channels, as well as the bed net channel 211. This reduces the need for adjustment mechanisms, simplifies the adjustment operation, and improves the efficiency of the adjustment operation.

[0079] In some embodiments, one of the third conveying members 210 is arranged in the movable module 240, and the movable module 240 also includes a first roller 241 and a first cutter 242. The third conveying member 210 arranged in the movable module 240 is used to wind the top cloth 3100 and to clamp the top of the bed net 2100. The first roller 241 is arranged downstream in the conveying direction of the third conveying member 210. The first cutter 242 is arranged between the third conveying member 210 and the first roller 241. The first roller 241 is used to drive the first cutter 242 to move along the first direction x to cut off the top cloth 3100 of the bed net 2100. The top fabric 3100 is wound around the bed net 2100 using the third conveyor 210. The third conveyor 210's conveying action in the second direction y drives the top fabric 3100 to move synchronously and adhere to the top of the bed net 2100. This allows the spring string 2000 to be bonded to the bed net 2100 in the second direction y while the top fabric 3100 is simultaneously bonded in the second direction y, achieving a synchronized bonding effect between the top fabric 3100 and the bed net 2100. Once the bed net 2100 is bonded, the first roller 241 drives the first cutter 242 to cut the top fabric 3100, thereby controlling the length of the top fabric 3100 to match the dimensions of the bed net 2100.

[0080] In some embodiments, another third conveying member 210 is arranged in the supporting module 230, and the supporting module 230 also includes a second roller 231 and a second cutter 232. The third conveying member 210 arranged in the supporting module 230 is used to wind the bottom cloth 3200, and the second roller 231 is correspondingly arranged below the first roller 241 along the third direction z, and the second cutter 232 is correspondingly arranged below the first cutter 242 along the third direction z. The second roller 231 drives the second cutter 232 to move along the first direction x to cut off the bottom cloth 3200 of the bed net 2100. The bottom fabric 3200 is wound around the third conveyor 210. The third conveyor 210's conveyance in the second direction y drives the bottom fabric 3200 to move synchronously and adhere to the bottom of the bed net 2100. This allows the spring string 2000 to be bonded to the bed net 2100 in the second direction y while the bottom fabric 3200 is simultaneously bonded in the second direction y, achieving a synchronized bonding effect between the bottom fabric 3200 and the bed net 2100. Once the bed net 2100 is bonded, the second roller 231 drives the second cutter 232 to cut the top fabric 3100, thereby controlling the length of the bottom fabric 3200 to match the dimensions of the bed net 2100.

[0081] In some embodiments, please combine Figure 1 and Figure 4The second driving member 220 includes a first power mechanism 222 and a plurality of screw rods 221 extending along the third direction z. The movable module 240 is movably connected to the screw rods 221. The first power mechanism 222 drives the screw rods 221 to rotate to drive the movable module 240 to move along the third direction z. By using multiple screw rods 221 to synchronously drive the movable module 240 to move, the stability and accuracy of the movement of the movable module 240 can be improved, thereby improving the reliability of the height adjustment operation of the bed net channel 211. Optionally, four screw rods 221 can be provided, and the four screw rods 221 are respectively provided at the four corners of the movable module 240, so that the force on the movable module 240 during the movement is more balanced. As an alternative, the movement of the movable module 240 along the third direction can also be transmitted by a gear rack.

[0082] Optionally, the multiple screw rods 221 may be connected to each other via a transmission structure 223 (such as a chain, a belt, etc.) to ensure synchronization of rotation among the multiple screw rods 221 .

[0083] In some embodiments, see Figures 6 to 10 The bed net bonding device 1000 further includes a feeding device 500, which is disposed upstream of the feeding mechanism 100 along the conveying direction of the spring string 2000. The feeding device 500 includes a welding and cutting mechanism 510, a loading mechanism 520, and a connecting assembly 530. The loading mechanism 520 includes a plurality of loading assemblies 521, each of which is used to allow the spring string 2000 to pass through. Any of the loading assemblies 521 can be moved to a corresponding loading position, which is connected to the inlet of the feeding mechanism 100. By providing multiple loading assemblies 521, when one of the loading assemblies 521 corresponds to a loading position, the remaining loading assemblies 521 are idle, allowing the remaining loading assemblies 521 to be replenished with spring strings 2000. When the loading assembly 521 at the loading position completes loading, any of the remaining loading assemblies 521 can be moved to a corresponding loading position and load the spring string 2000. On the one hand, this setting saves the waiting time for the loading component 521 to replenish the spring string 2000. On the other hand, each loading component 521 can be connected to a spring machine respectively, that is, multiple spring machines supply spring strings 2000 to a bed net bonding device 1000 at the same time. This setting can adapt to the rhythm difference between the spring machine and the bed net bonding device 1000, that is, the speed at which the spring machine provides the spring string 2000 is roughly the same as the speed at which the bed net bonding device 1000 consumes the spring string 2000, thereby reducing time waste in the production process of bonding the bed net 2100.

[0084] In some embodiments, see Figure 9 and Figure 10The feeding mechanism 520 includes a support plate 522 and a third driving member 523. The support plate 522 is provided with a chute 5221. Multiple feeding assemblies 521 are slidably disposed in the chute 5221. The chute 5221 is provided with a curved section 5222 that protrudes toward the feeding position. The third driving member 523 is disposed on a side of the chute 5221 away from the feeding mechanism 100. The driving direction of the third driving member 523 is the same as the extension direction of the chute 5221. The third driving member 523 drives any feeding assembly 521 to slide to the curved section 5222. The feeding assembly 521 located in the curved section 5222 is located corresponding to the feeding position. The chute 5221 structure can improve the smoothness of the switching of multiple feeding assemblies 521 to the feeding position, thereby shortening the switching time. The curved section 5222 is disposed toward the loading position, shortening the distance between the outlet of the loading assembly 521 and the feeding mechanism 100. Once the loading assembly 521 enters the curved section 5222, it can supply the spring string 2000 to the feeding mechanism 100. By using the third driving member 523 to drive the loading assembly 521 within the chute 5221, multiple loading assemblies 521 can be automatically switched, improving switching convenience.

[0085] Exemplarily, the third driving member 523 includes a power mechanism 5231 and a conveyor belt 5232. The conveyor belt 5232 is arranged on the side of the slide 5221 away from the feeding mechanism 100. The power mechanism 5231 can be a motor, etc. The power mechanism 5231 rotates forward or reverse to drive the conveyor belt 5232 to move along the two ends of the slide 5221. Multiple loading components 521 are arranged on the conveyor belt 5232. The conveyor belt 5232 drives the loading components 521 to move and enables one of the loading components 521 to enter the curved section 5222 along the slide 5221.

[0086] Optionally, multiple loading components 521 are arranged along the second direction y. In this case, the chute 5221 can be extended along the second direction y. The protruding direction of the curved section 5222 can be perpendicular to the second direction, that is, the curved section protrudes toward the first direction x (e.g., Figure 9 Similarly, the conveyor belt 5232 may also be extended along the second direction y, and the conveyor belt 5232 may be arranged parallel to the chute 5221.

[0087] Optionally, in order to further improve the sliding smoothness of the loading component 521 in the slide groove 5221, the loading component 521 can also be connected to the slide groove 5221 through a pulley 525, that is, the pulley 525 is connected to the bottom of the loading component 521, and the pulley 525 is slidably set in the slide groove 5221, thereby reducing the friction between the loading component 521 and the slide groove 5221, so that the loading component 521 moves more smoothly in the slide groove 5221.

[0088] In some embodiments, the feeding mechanism 520 further includes a pressure plate 524, which is disposed on top of the feeding assembly 521. The pressure plate 524 is movable along the third direction z and is configured to abut against the top of the spring string 2000. The pressure plate 524, in conjunction with the feeding assembly 521, can clamp the springs axially along the spring string 2000, preventing the spring string 2000 from bouncing during the feeding process and improving the stability of the spring string 2000 feeding process. The pressure plate 524 is movable along the third direction z, thereby enabling the height of the feeding mechanism 520 to be adjusted to accommodate spring strings 2000 of varying heights.

[0089] In some embodiments, please combine Figure 7 and Figure 8The welding and cutting mechanism 510 is disposed between the feeding mechanism 100 and the loading mechanism 520. It is used to cut the continuous spring string 2000 into predetermined lengths. The welding and cutting mechanism 510 includes a third cutter 511 and a pair of ultrasonic horns 512 and welding blades 513. The ultrasonic horns 512 and welding blades 513 can be separated to allow the spring string 2000 to pass through. The contact surfaces of the welding blades 513 and ultrasonic horns 512 are provided with a slot 5121 through which the third cutter 511 can pass. When the ultrasonic horns 512 and welding blades 513 approach each other, the third cutter 511 passes through the slot 5121 and severs the spring string 2000. The welding and cutting mechanism 510 can cut the continuous spring string 2000 into predetermined lengths, ensuring that the length of the spring string 2000 meets the design specifications of the bed net 2100. The third cutter 511 can cut the fabric between two adjacent springs at a predetermined length, thereby shearing the spring string 2000. Typically, the spring string 2000 is formed by wrapping multiple springs with fabric. The fabric between adjacent springs is welded to separate each spring into its own separate bag chamber. Therefore, the third cutter 511 typically cuts along the weld between two adjacent springs, preventing the fabric of the spring string 2000 from unraveling after cutting. To further prevent the fabric from unraveling after cutting with the third cutter 511 due to a weak weld, the welder 513 and ultrasonic horn 512 perform another weld on the fabric before the third cutter 511, ensuring a secure weld between the two layers of fabric between adjacent springs. The welder 513 and ultrasonic horn 512 can approach each other and clamp the fabric of the spring string 2000, welding the two layers together under the action of ultrasound. Since a groove 5121 is provided on the contact surface of the welding knife 513 and the ultrasonic horn 512, the groove 5121 separates the welding knife 513 and the ultrasonic horn 512 into two parts, and two adjacent welds can be formed when the welding knife 513 and the ultrasonic horn 512 are welded to each other, with a gap between the two welds. The third cutter 511 cuts through the gap and cuts the two welds together. In this way, the front and rear positions of the incision on the spring string 2000 each have a weld, which effectively prevents the fabric of the spring string 2000 from spreading. Optionally, the third cutter 511 can be extended along the length direction of the groove 5121. When the ultrasonic horn 512 and the welding knife 513 contact each other to clamp the fabric, the third cutter 511 cuts the fabric. Or in other examples, such as Figure 7 and Figure 8 As shown, the length of the third cutter 511 is smaller than the height of the cloth, and the motor is used to drive the third cutter 511 to move along the cutting groove 5121 to cut the cloth.

[0090] Optionally, the relative movement direction of the welding knife 513 and the ultrasonic horn 512 may be perpendicular to the feeding direction of the spring string 2000 , that is, the ultrasonic horn 512 moves closer to or away from the welding knife 513 along the second direction y.

[0091] In some embodiments, the welding and cutting mechanism 510 further includes a fixed frame 514, a fourth driving member 515 and a mounting member 516 disposed on the fixed frame 514. The welding blade 513 is fixedly disposed on the fixed frame 514. The ultrasonic horn 512 is slidably disposed on the fixed frame 514 via the mounting member 516. The fourth driving member 515 drives the ultrasonic horn 512 toward or away from the welding blade 513. The ultrasonic horn 512 is elastically connected to the mounting member 516 via an elastic member 517. The elastic member 517 is used to provide a buffer when the ultrasonic horn 512 squeezes the welding blade 513. The ultrasonic horn 512 is slidably connected to the fixed frame 514 via the mounting member 516. In this way, the ultrasonic horn 512 can slide under the drive of the fourth driving member 515, automatically cooperating with the welding blade 513 to complete welding. During welding, the ultrasonic horn 512 needs to squeeze the welding blade 513, creating a certain squeezing force between the two, ensuring that the ultrasonic horn 512 and the welding blade 513 can fit together to achieve a good welding effect. The elastic connection between the ultrasonic horn 512 and the mounting member 516 prevents direct rigid contact between the ultrasonic horn 512 and the welding blade 513. When the ultrasonic horn 512 squeezes the welding blade 513, it provides a certain buffering effect, preventing collision or wear between the two, thereby increasing the service life of the ultrasonic horn 512 and the welding blade 513. By way of example, the fourth drive member 515 can be a power mechanism such as a motor, and the elastic member 517 can be a spring, etc.

[0092] Optionally, the mounting member 516 includes a pair of spaced guide rails 5161 and two first connecting rods 5162. The pair of guide rails 5161 are fixedly disposed on the upper and lower sides of the fixed frame 514, and the extension direction of the guide rails 5161 is the same as the movement direction of the ultrasonic horn 512. The ends of the first connecting rod 5162 are respectively slidably connected to the two guide rails 5161, and the first connecting rod 5162 is arranged perpendicular to the guide rails 5161. The two first connecting rods 5162 are interconnected by an elastic member 517 (e.g., a spring). The ultrasonic horn 512 is disposed on one of the first connecting rods 5162, and the fourth driving member 515 is disposed on the other first connecting rod 5162. The fourth driving member 515 drives one of the first connecting rods 5162 to slide, and the driving force is transmitted to the other first connecting rod 5162 via the elastic member 517, thereby driving the ultrasonic horn 512 to move. By utilizing the guiding effect of the guide rail 5161, the ultrasonic horn 512 can be made more stable during movement, thereby improving the stability and docking accuracy of the ultrasonic horn 512 when cooperating with the welding knife 513. Optionally, the fourth driving member 515 may include a rotary structure 5151 (e.g., a rotary motor) and a second connecting rod 5152, one end of the second connecting rod 5152 is rotatably connected to the eccentric position of the rotary structure 5151, and the other end of the second connecting rod 5152 is rotatably connected to the first connecting rod 5162 away from the ultrasonic horn 512. It can be understood that the rotary structure 5151, the second connecting rod 5152 and the first connecting rod 5162 constitute a crank slider mechanism. Under the action of the rotary mechanism outputting the rotational motion, the second connecting rod 5152 converts the rotational motion into linear motion through the swinging action, thereby driving the first connecting rod 5162 to move linearly, thereby realizing the movement of the ultrasonic horn 512 approaching or moving away from the welding knife 513. Optionally, the swivel structure 5151 of the fourth driving member 515 can be fixedly connected to the fixed frame 514. Alternatively, in other examples, the swivel structure 5151 can be slidably mounted on the fixed frame 514. For example, the swivel structure 5151 is fixed to a mounting plate 5153, which is slidably connected to the fixed frame 514. Two second connecting rods 5152 can be provided, each of which has one end hinged at an eccentric position of the swivel structure 5151. The other end of one of the second connecting rods 5152 is hinged to the first connecting rod 5162, and the other end of the other second connecting rod 5152 is hinged to the fixed frame 514. The rotation of the swivel structure 5151 drives the mounting plate 5153 and the first connecting rod 5162 to slide relative to the fixed frame 514, thereby moving the ultrasonic welding head 512 toward or away from the welding blade 513.

[0093] In some embodiments, please combine Figure 2 and Figure 6The connecting component 530 is arranged on the side of the welding and cutting mechanism 510 facing the feeding mechanism 100. The connecting component 530 includes a fifth driving member 531 and a pair of clamps 532. The fifth driving member 531 drives the clamps 532 to reciprocate along the first direction x between the feeding mechanism 100 and the welding and cutting mechanism 510. The clamps 532 can pass through the welding and cutting mechanism 510 and are used to clamp the spring string 2000 at the loading position. The clamps 532 pull the spring string 2000 and feed it into the feeding mechanism 100. The clamping plates 532 clamp the spring string 2000, and the clamping plates 532 can reciprocate between the feed mechanism 100 and the welding and cutting mechanism 510. Thus, after passing through the welding and cutting mechanism 510, the spring string 2000 can be clamped by the clamping plates 532 and pulled into the feed mechanism 100 by the pulling action of the clamping plates 532. This achieves a smooth transition of the spring string 2000 from the loading mechanism 520 to the feed mechanism 100, improving the stability and reliability of the spring string 2000 during movement. It is understood that the pair of clamping plates 532 can clamp together to clamp the spring string 2000 along the radial direction of the springs, and the two clamping plates 532 can also move away from each other to release the spring string 2000. For example, the pair of clamping plates 532 achieves the mutual clamping or releasing action via a power structure such as a motor. After reaching the feed mechanism 100, the spring string 2000 can continue to move under the conveying action of the feed mechanism 100.

[0094] In some embodiments, refer back to Figure 4 and Figure 5The bed net bonding device 1000 also includes a cloth feeding mechanism 600, which is arranged on the side of the combined platform 200 away from the bed net channel 211, and the cloth feeding mechanism 600 includes two material racks 610 and two pressure rollers 620. The material rack 610 is used to place the cloth rolls 3000 of the top cloth 3100 and the bottom cloth 3200 of the bed net 2100. The combined platform 200 includes two third conveying members 210 spaced apart along the third direction z, and a bed net channel 211 is formed between the two third conveying members 210. One of the third conveying members 210 and one of the pressure rollers 620 is used to wind the top cloth 3100, and the other third conveying member 210 and the other pressure roller 620 are used to wind the bottom cloth 3200. The two pressure rollers 620 respectively apply extrusion pressure to the two third conveying members 210 toward the bed net channel 211, and the two third conveying members 210 can convey the top cloth 3100 and the bottom cloth 3200 along the second direction y. The pressure roller 620 is used to apply an extrusion pressure to the third conveying member 210. On the one hand, the two third conveying members 210 can clamp the bed net 2100 along the axial direction of the spring to prevent the spring string 2000 from bouncing or deforming during the bonding or conveying process. On the other hand, the pressure roller 620 can adhere the surface cloth (top cloth 3100, bottom cloth 3200) to the surface of the third conveying member 210. With the help of the conveying effect of the third conveying member 210, the top cloth 3100 and the bottom cloth 3200 are respectively bonded to the top and bottom surfaces of the bed net 2100.

[0095] Optionally, the glue gun 410 can be provided with multiple groups of nozzles 411, and the setting directions of each group of nozzles 411 are set at an angle. For example, one group of nozzles 411 is set toward the spring string 2000 or the bed net 2100, for example, the spraying direction is set along the second direction y, and another group of nozzles 411 is set toward the top cloth 3100 or the bottom cloth 3200, for example, the spraying direction is set along the third direction z. In this way, the glue gun 410 can spray glue on the top cloth 3100 and the bottom cloth 3200, which facilitates the bonding of the cloth and the bed net 2100.

[0096] In some embodiments, see Figure 5The bed net bonding device 1000 also includes a fabric joining mechanism 700, which is disposed between the fabric roll 3000 and the pressure roller 620. The fabric joining mechanism 700 includes two crossbeams 710 spaced apart along the third direction z. One of the crossbeams 710 is provided with a heating structure 720. The two crossbeams 710 can be brought together to press the face fabric. The heating mechanism is used to heat-weld the two face fabrics together. When the fabric in the fabric roll 3000 is used up and needs to be replaced with a new one, the new and old fabric rolls 3000 need to be connected. Therefore, by providing the fabric joining mechanism 700, the fabric on the two fabric rolls 3000 can be heated and welded, thereby connecting the fabric on the two fabric rolls 3000, enabling the replacement of the fabric rolls 3000 and a continuous supply of face fabric. Placing the heating structure 720 on one of the crossbeams 710 can reduce the space occupied by the heating structure 720, making the fabric connection structure more compact. The two crossbeams 710 can be brought close together to squeeze the fabric, and the two fabrics can be connected under the squeezing and heating effects. For example, the heating structure 720 can be a heating wire or the like.

[0097] Second, see Figure 11 The present application also provides a method for bonding a bed net 2100, comprising the following steps:

[0098] S100. The feeding mechanism 100 provides a spring string 2000 along a first direction x;

[0099] S200. The glue gun 410 moves along the first direction x and sprays glue on at least one of the spring string 2000 located on the feeding mechanism 100 or the bed net 2100 located on the assembly platform 200. The annular assembly 420 moves synchronously with the glue gun 410, and the straight section 421 of the annular assembly 420 is connected to the gap between the feeding mechanism 100 and the assembly platform 200.

[0100] S300. The pushing mechanism 300 pushes the spring string 2000 along the second direction y. The spring string 2000 passes through the straight section 421 from the feeding mechanism 100 to the assembly platform 200. The spring string 2000 and the bed net 2100 are bonded to each other.

[0101] In this way, the feeding mechanism 100 provides the spring string 2000, which can be arranged in place within the feeding mechanism 100 along the first direction x. While the glue gun 410 is spraying glue on the spring string 2000 and the bed net 2100, the annular assembly 420 and the glue gun 410 move synchronously. Therefore, the straight section 421 of the annular assembly 420 can fill the gap between the feeding mechanism 100 and the assembly platform 200. At this time, the annular assembly 420 does not obstruct or interfere with the movement of the pushing mechanism 300, the spring string 2000, or the glue gun 410. Furthermore, the annular assembly 420 ensures a smooth transition of the spring string 2000 during its push to the assembly platform 200, preventing the spring string 2000 from getting stuck or falling into the gap. Finally, the pushing mechanism 300 pushes the spring string 2000 into the assembly platform 200 along the second direction y, thereby bonding the spring string 2000 to the bed net 2100.

[0102] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
