Description

Technical Field

[0001] The present application relates to the technical field of mattress processing. Specifically, it relates to a sponge picking and conveying device, a bed net edge sealing device, and a bed net combined production equipment. Background Art

[0002] An independent pocket spring bed net is a bed net formed by combining individual springs into rows through ultrasonic hot melt technology and then bonding them with hot melt adhesive. Then, a sponge layer is adhered onto the bed net to form a mattress. During mattress production, to reinforce the edge of the bed net and make the bed net size stable and not easily deformed, sponges or harder strip materials are often adhered to the side of the bed net. However, for a bed net with upper and lower fabrics, the existing equipment cannot paste and shape the upper and lower fabrics.

[0003] Currently, some pasting and shaping devices in related technologies adopt the following method. The non-woven fabrics on the upper and lower sides of the bed net are bent outwards by upper and lower fabric folding components. While spraying glue on the bed net, the folding parts of the non-woven fabrics are also sprayed with glue. Then, when the sponge strip is bonded to the bed net, the non-woven fabric can also be adhered to the upper and lower end faces of the sponge strip, making the bonding of the sponge strip more firm.

[0004] However, the inventors of the present application found that according to the above solution, during the feeding process, when moving the sponge strip, due to uneven frictional force, the sponge strip is prone to tilting, and manual adjustment of the position of the sponge strip is required, reducing the production efficiency.

[0005] The content in the background art section is only the technology known to the applicant and does not necessarily represent the prior art in this field. Summary of the Invention

[0006] According to one aspect of the present application, the present application provides a sponge picking and conveying device, including a picking mechanism. The picking mechanism is arranged above the placement platform and on one side of the feeding mechanism. The feeding mechanism conveys the sponge strip to the picking mechanism. The picking mechanism can move relative to the feeding mechanism. The picking mechanism approaches the feeding mechanism to pick up the sponge strip conveyed on the feeding structure, and the picking mechanism moves away from the feeding mechanism and releases the sponge strip, so that the sponge strip falls onto the placement platform.

[0007] According to one aspect of the present application, the present application further provides a bed net edge sealing device, which includes a frame, a placement platform, a feeding mechanism, a cloth clamping mechanism, and a glue spraying mechanism. The placement platform is arranged on the frame. The feeding mechanism is arranged above the placement platform and conveys sponge strips to be picked up in the horizontal direction. The cloth clamping mechanism includes an upper cloth clamping component and a lower cloth clamping component. The upper cloth clamping component is slidably connected to the frame up and down and is located on one side of the placement platform for clamping and lifting the upper surface cloth at the edge of the bed net. The lower cloth clamping component is arranged on the frame and is located below the upper cloth clamping component for clamping and lifting the lower surface cloth at the edge of the bed net. The glue spraying mechanism is arranged on the frame and slides up and down with the upper cloth clamping component, reciprocates above the placement platform along the side of the bed net, sprays glue on the side of the bed net, the upper surface cloth, and the lower surface cloth, and the glue spraying mechanism is located at the edge end of the frame to avoid the sponge picking and conveying device and push the sponge strip into the channel on the side of the bed net.

[0008] According to one aspect of the present application, the present application further provides a bed net combined production device, which includes a bed net edge sealing device and a bed net bonding device. The bed net bonding device includes a combination platform, a spring string feeding mechanism, and a sponge strip feeding mechanism. The combination platform is arranged on one side of the bed net edge sealing device to pre-install the bed net. The spring string feeding mechanism is used to cut a continuous spring string into a predetermined length and convey it to the combination platform. The sponge strip feeding mechanism is used to convey sponge strips to the combination platform. The bonding mechanism bonds the spring string or sponge strip located on the combination platform together to form a bed net with sponge strips at both ends and a bagged spring string in the middle.

[0009] In summary, the present application has the following beneficial technical effects.

[0010] 1. When the feeding mechanism sends the sponge strip to the preset position, the picking mechanism promptly picks up the sponge strip. Through the cooperation of the picking mechanism and the feeding mechanism, it can ensure that the sponge strip is accurately and quickly picked up and released, thereby improving production efficiency.

[0011] 2. During the edge sealing process, the cloth clamping mechanism firmly clamps the bed net, the upper surface cloth, and the lower surface cloth. The glue spraying mechanism reciprocates between the cloth clamping mechanism and the sponge picking and conveying device to ensure that the glue can be evenly sprayed on the side of the bed net, the upper surface cloth, and the lower surface cloth, ensuring the precise positioning and bonding of the sponge strip, the bed net, and the cloth, and avoiding quality problems caused by improper operation.

[0012] 3. By precisely controlling the working timing and movement trajectory of each device, with the cooperation of the bed net bonding device and the bed net edge sealing device, it can ensure the precise positioning and bonding of raw materials such as spring strings and sponge strips, thereby improving production efficiency.

Obviously, the described embodiments are part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0037] According to one aspect of this application, this application provides a sponge picking and delivering device, Figure 1 A schematic side view of the sponge picking and delivering device according to the embodiment of this application is shown. Figure 2The figure shows a schematic top view of the guide member in the embodiment of the present application. Figure 3 The figure shows a schematic side view of the picking component in the embodiment of the present application. Figure 4 The figure shows a schematic structural view of the limiting component in the embodiment of the present application. Figure 5 The figure shows a schematic structural view of the limiting member in the embodiment of the present application.

[0038] According to an exemplary embodiment, as Figure 1 shown, the sponge picking and conveying device includes a picking mechanism. The picking mechanism is located above the bonding position and can pick up the sponge strip through reciprocating motion and then release the sponge strip, so that the sponge strip falls to the bonding position. It should be noted that the bonding position refers to the designated position for placing the sponge strip before bonding with the bed net.

[0039] During the operation of the above-described embodiment, the picking mechanism moves toward the side close to the sponge strip, and the sponge strip is pushed to the side close to the picking mechanism, and the picking mechanism picks up the sponge strip. After picking up the sponge strip, the picking mechanism sends the sponge strip above the bonding position and releases the sponge strip. Under the action of gravity, the sponge strip freely falls to the bonding position, which can ensure that the sponge strip is accurately and quickly picked up and released, thereby improving production efficiency.

[0040] According to an exemplary embodiment, as Figure 1 and Figure 2 shown, the sponge picking and conveying device includes a picking mechanism. The picking mechanism includes a carrier 11 and at least one picking component 12. For example, the carrier 11 can be a rectangular vertical plate. The carrier 11 is connected to an external power mechanism. Under the control of the external power mechanism, the carrier 11 reciprocates along the Figure 1 horizontal plane shown. For example, the movement mode of the carrier 11 can be horizontal sliding or upward flipping.

[0041] In the case of selecting the horizontal sliding mode, the external power mechanism can be driven by a telescopic cylinder, a motor through a crank-slider mechanism, a lead screw, a gear-rack, etc.

[0042] For example, in the case of selecting a telescopic cylinder, the rectangular vertical plate is fixedly connected to the movable end of the telescopic cylinder. In the case of selecting a crank-slider mechanism, one end of the crank is fixedly connected to the output shaft of the motor, and the other end is rotatably connected to one end of the slider. The other end of the slider is fixedly connected to the rectangular vertical plate. In the case of selecting a lead screw, one end of the lead screw is fixedly connected to the output shaft of the motor, and the other end is fixedly connected to the rectangular vertical plate. In the case of selecting a gear-rack, the gear is coaxially fixedly connected to the output shaft of the motor and meshes with the rack. The end of the rack is fixedly connected to the rectangular vertical plate.

[0043] In the case of selecting the upward flipping mode, the external power mechanism can be driven by a rotary cylinder, driven by connecting a rotating arm through a cylinder, driven by connecting a four-bar mechanism through a motor, etc.

[0044] For example, in the case of selecting a rotary cylinder, the output end of the rotary cylinder is fixedly connected to the rectangular vertical plate. In the case of selecting a rotating arm, the rectangular vertical plate is rotatably connected to the frame, one end of the rotating arm is rotatably connected to the output end of the cylinder, and the other end is fixedly connected to the rectangular vertical plate. Or the output end of the cylinder is directly rotatably connected to the rectangular vertical plate.

[0045] In the case of selecting a four-bar mechanism, the rectangular vertical plate is rotatably connected to the frame, the adjacent ends of the four bars are rotatably connected to each other, one end of the link at the head is fixedly connected to the output shaft of the motor, and one end of the link at the tail is rotatably connected to the rectangular vertical plate, so that the rectangular vertical plate realizes flipping.

[0046] The external power mechanism is electrically connected to an external control source, and the external power mechanism drives the carrier 11 to move in response to a motion instruction output by the external control source.

[0047] As Figure 3 shown, at least one picking component 12 is arranged at intervals in the horizontal direction on the carrier 11 and is electrically connected to the external control source. There can be multiple picking components 12, and multiple picking components are arranged in multiple rows in the vertical direction. The multiple rows of picking components can pick up multiple sponge strips at the same time and release the sponge strips one by one to the bonding position.

[0048] The picking component 12 reciprocates in the horizontal direction along with the carrier 11 in response to a preset instruction output by the external control source to pick up or release the sponge strip. For example, the picking component 12 can be a pin inserting device.

[0049] For example, in the case of selecting a pin inserting device, the pin extends and inserts into the sponge strip by the acting force of the sponge strip. The pin retracts and pulls out the pin by the acting force of the carrier 11 to release the sponge strip.

[0050] During the operation of the above implementation, the external control source outputs a motion instruction. The external power mechanism drives the carrier 11 to move to the position for picking up the sponge strip in response to the motion instruction output by the external control source. The picking component 12 picks up the sponge strip in response to a preset instruction output by the external control source.

[0051] After the picking is completed, the external power mechanism drives the carrier 11 to reset in response to the motion instruction output by the external control source again. The picking component 12 releases the sponge strip in response to a preset instruction output by the external control source. Thus, it can ensure that the sponge strip is picked up and released accurately and quickly, thereby improving the production efficiency.

[0052] According to the exemplary embodiment, asFigure 1 As shown, the material taking mechanism further includes a movable stopper 13. The movable stopper 13 is arranged below the carrier 11. The movable stopper 13 moves upward in the vertical direction to limit the sponge strip in a limited space during the falling process, so that the sponge strip falls at a predetermined position and to prevent the sponge strip from flipping during the falling process.

[0053] For example, the movable stopper 13 can be a telescopic rod or one or more rectangular plates that move up and down.

[0054] For example, the number of the movable stoppers 13 can be multiple, and the multiple movable stoppers 13 are distributed at intervals to further limit the sponge strip.

[0055] In the case of selecting a telescopic rod, the telescopic rod is fixedly arranged vertically, and the movable end of the telescopic rod extends vertically upward. In the case of selecting a rectangular plate, the rectangular plate is arranged vertically and can be driven by a cylinder drive, an electric cylinder drive, or by a motor cooperating with a common linear transmission mechanism (such as a crank-slider mechanism, a gear-rack mechanism, a lead screw-nut, a synchronous belt drive, a chain drive, etc. These transmission mechanisms are common technical means for those skilled in the art when designing linear motion, and the specific connection methods will not be described one by one).

[0056] During the operation of the above implementation, during the falling process of the sponge strip, the movable stopper 13 extends upward. It can effectively prevent the sponge strip from rolling leftward in the horizontal plane, resulting in the deviation of the final falling position, thus being easy to improve the accuracy of the sponge strip falling, and further improving the production efficiency.

[0057] It should be further noted that the carrier can be set to move downward to release the sponge strip after the sponge strip approaches the bonding position. In this case, the movable stopper 13 can be not provided.

[0058] According to the exemplary embodiment, as Figure 2 shown, the material taking mechanism further includes a guide member 14. The guide member extends in the vertical direction and has an "L" or "U" shaped horizontal cross-section. The guide member 14 is movably connected to both sides of the carrier 11. The guide members on both sides can move relative to each other to approach each other to guide the sponge strip or move away from each other to avoid the sponge strip. For example, the guide member 14 can be a U-shaped plate or an L-shaped plate.

[0059] For example, the movement drive of the guide member 14 can be a cylinder drive, a linear motor drive, or other drive methods for linear motion.

[0060] In the case of selecting a cylinder, the fixed end of the cylinder is fixedly connected to the carrier 11, and the movable end is fixedly connected to the guide member 14.

[0061] When a linear motor is selected, the linear motor is fixedly connected to the carrier 11. The output shaft of the linear motor is fixedly connected to the guide member 14.

[0062] During the operation of the above-described embodiment, when the picking component 12 does not pick up the sponge strip, the guide members 14 on both sides move away from each other to avoid the sponge strip. A position space is reserved to facilitate the picking component 12 to pick up the sponge strip. When the picking component 12 does not release the sponge strip, the guide members 14 move relatively in the direction of approaching each other, and enclose a vertical channel with the carrier 11 to guide the falling sponge strip, thereby easily improving the accuracy of the falling of the sponge strip and further improving the production efficiency.

[0063] According to the exemplary embodiment, as Figure 1 shown, a sponge picking and conveying device further includes a pushing mechanism 2. The pushing mechanism 2 includes a driving member 21 and a pushing member 22. The driving member 21 is movably connected to the lower oblique side of the carrier 11, and the pushing member 22 is fixedly connected to the driving member 21.

[0064] For example, the driving member 21 can be a cylinder, a linear motor, a rotary motor cooperating with a gear rack, or other driving devices for linear motion. The pushing member 22 can be a pushing plate or a pushing rod.

[0065] When a cylinder is selected, the movable end of the cylinder is fixedly connected to the pushing plate or the pushing rod. When a linear motor is selected, the output shaft of the linear motor is fixedly connected to the pushing plate or the pushing rod.

[0066] During the operation of the above-described embodiment, after the sponge strip falls to the bonding position, the driving member 21 drives the pushing member 22 to move. The pushing member 22 pushes the sponge strip to move to the side of the bed net and applies a certain pressure to the sponge strip to make the sponge strip fully bond with the side of the bed net. Through an automated design, the time for manual bonding is shortened, and the production efficiency is further improved.

[0067] According to the exemplary embodiment, as Figure 4 and Figure 5 shown, the picking mechanism further includes a limiting component. The limiting component includes a pair of limiting members 151. The pair of limiting members 151 are arranged on the pushing member 22, and at least one end of the sponge strip is pushed by an external driving mechanism to move in opposite directions or to flip, so that both ends of the sponge strip are aligned with both ends of the bed net. For example, the limiting member 151 can be a limiting plate or a limiting rod.

[0068] When the opposite movement is selected, the external driving mechanism can be a telescopic cylinder, or a way of driving a conveyor belt or a conveyor chain by a motor.

[0069] In the case of selecting a telescopic cylinder, two telescopic cylinders can be selected to drive two limit members 151 respectively, wherein the fixed end of the telescopic cylinder is connected to the pushing member 22, and the movable end is connected to the two limit members 151.

[0070] In the case of selecting a motor to drive a conveyor belt or a conveyor chain, the two limit members 151 are respectively connected to both sides of the conveyor belt or the conveyor chain, that is, one is connected to the slack side and the other is connected to the tight side, to achieve opposite movement.

[0071] In the case of selecting a flipping movement, the external driving mechanism can be a rotary cylinder or a rotary motor.

[0072] For example, in the case of selecting a rotary cylinder, the fixed end of the rotary cylinder is fixedly connected to the pushing member 22, and the movable end is fixedly connected to the rotating plate or the rotating rod. In the case of selecting a rotary motor, the rotary motor is fixedly connected to the pushing member 22. The output shaft of the rotary motor is fixedly connected to the rotating plate or the rotating rod to make the rotating plate or the rotating rod rotate 90°.

[0073] When the above-mentioned implementation scheme is in operation, after the picked sponge strip falls to the bonding position, the movable stop member 13 and the guiding member 14 respectively perform a reset movement. The external control source outputs a rotation instruction, and the external driving mechanism responds to the rotation instruction output by the external control source and drives the paired limit members 151 to move towards each other.

[0074] The two limit members 151 push at least one end of the sponge strip to move in the horizontal direction. After adjusting the position of the sponge strip, the pushing mechanism 2 then pushes the sponge strip to the side of the bed net for bonding, thereby facilitating the improvement of the alignment rate between the sponge strip and the bed net, and further improving the quality of the finished bed net.

[0075] According to one aspect of the present application, the present application provides a bed net edge sealing device. Figure 1 Fig. shows a schematic side view of the sponge picking and conveying device according to an embodiment of the present application. Figure 4 Fig. shows a schematic structural diagram of the limit assembly in an embodiment of the present application. Figure 6 Fig. shows a schematic structural diagram of the bed net edge sealing device according to an embodiment of the present application. Figure 7 Fig. shows a plan view of the cloth clamping mechanism 6 and the glue spraying mechanism 7. Figure 7 Fig. shows a schematic structural diagram of the centering mechanism in an embodiment of the present application. Figure 9 Fig. shows a schematic structural diagram of the moving mechanism in an embodiment of the present application.

[0076] According to an exemplary embodiment, as Figure 1 and Figure 4As shown, a bed net edge sealing device includes a placement platform 3 and a feeding mechanism 4. A driving member 21 is fixedly connected to the placement platform 3. A passing portion is provided on the placement platform 3. For example, the passing portion can be a through hole or a slit. The feeding mechanism 4 is disposed above the driving member 21 and on one side of the material taking mechanism.

[0077] Optionally, the feeding mechanism 4 is an endless conveyor belt. The endless conveyor belt is horizontally arranged and disposed above the driving member 21. Driven by the power of an external motor, it conveys the sponge strips to be picked up in the horizontal direction.

[0078] Optionally, the feeding mechanism 4 includes a placement plate and a pushing plate. The placement plate is horizontally arranged and fixedly connected to the placement platform 3. The placement plate is located above the driving member 21. The pushing plate is slidably connected to the placement plate through an external control mechanism, and the sliding direction of the pushing plate is the horizontal direction.

[0079] For example, the external control mechanism can be a cylinder, a linear motor or other driving methods of linear motion. When a cylinder is selected, the fixed end of the cylinder is fixedly connected to the placement plate, and the movable end is fixedly connected to the pushing plate. When a linear motor is selected, the linear motor is fixedly connected to the placement plate. The output shaft of the linear motor is fixedly connected to the pushing plate.

[0080] During the operation of the above embodiments, the feeding mechanism 4 drives the sponge strips to be picked up to move towards the material taking mechanism, enabling the material taking mechanism to pick up the sponge strips in a timely manner, facilitating the subsequent processing operation of bed net edge sealing, and improving the production efficiency through an automated design.

[0081] According to the exemplary embodiment, as Figure 1 and Figure 7 shown, a bed net edge sealing device further includes a frame 5 and a cloth clamping mechanism 6. The frame 5 is erected on the ground. The placement platform 3 is fixedly connected to the frame 5. The cloth clamping mechanism 6 includes an upper cloth clamping assembly 61 and a lower cloth clamping assembly 62.

[0082] The upper cloth clamping assembly 61 includes a first pressing plate 611 and a first clamping plate 612. The first pressing plate 611 is liftably arranged on the frame 5 through a cylinder and is located above the placement platform 3. The first pressing plate 611 has a front end, and the front end of the first pressing plate 611 is arranged towards the direction close to the bearing member 11.

[0083] The front end of the first pressing plate 611 is provided with a bent section inclined upwards. The first clamping plate 612 is liftably arranged on the frame 5 through a cylinder and is located on the side of the bent section of the first pressing plate 611 close to the bearing member 11. The first clamping plate 612 can abut against the bent section of the first pressing plate 611.

[0084] The lower cloth clamping assembly 62 includes a second pressing plate 621 and a second clamping plate 622. The second pressing plate 621 is divided into a rear end and a front end along the direction in which the first pressing plate 611 approaches the bearing member 11. The rear end of the second pressing plate 621 is fixedly connected to the machine frame 5, and the front end is provided with a bent section inclined downward. The second clamping plate 622 is arranged on the front end of the second pressing plate 621 in a liftable manner through a cylinder, and the second clamping plate 622 can abut against the bent section of the second pressing plate 621.

[0085] During the operation of the above-described embodiment, the cylinder drives the first pressing plate 611 to move, and the first pressing plate 611 and the second pressing plate 621 are respectively in contact with the upper cloth and the lower cloth of the bed net. Then, the cylinder drives the first clamping plate 612 and the second clamping plate 622 to move towards each other. A cloth clamping space is left between the bent section of the first pressing plate 611 and the first clamping plate 612, and a cloth clamping space is left between the bent section of the second pressing plate 621 and the second clamping plate 622, so that the upper cloth and the lower cloth can be in the cloth clamping space. Finally, the cylinder drives the first clamping plate 612 and the second clamping plate 622 to move away from each other. The first clamping plate 612 abuts tightly against the bent section of the first pressing plate 611, and the second clamping plate 622 abuts tightly against the bent section of the second pressing plate 621, so that the sponge strip is easily and tightly attached to the side of the bed net, thereby facilitating the improvement of the production quality.

[0086] According to the exemplary embodiment, as Figure 6 shown, a bed net edge sealing device further includes a glue spraying mechanism 7. The glue spraying mechanism 7 moves up and down synchronously with the upper cloth clamping assembly 61. The glue spraying mechanism 7 includes a mounting profile 71, a spray gun 72, and a moving motor 73. The mounting profile 71 is fixedly connected to the machine frame 5. The spray gun 72 is slidably connected to the mounting profile 71 through a slide rail and a slider, and the sliding direction of the spray gun 72 is the horizontal direction. The moving motor 73 is drivingly connected to the spray gun 72 through a synchronous belt, and the moving motor 73 drives the spray gun 72 to move horizontally to spray glue on the spring cloth bag on the outer side of the bed net.

[0087] Three to six groups of nozzles are vertically arranged on the spray gun 72. The two outermost groups of nozzles are respectively aligned with the bent sections of the first pressing plate 611 and the second pressing plate 621 for spraying glue on the non-woven fabric areas on the bent sections.

[0088] During the operation of the above-described embodiment, the moving motor 73 drives the spray gun 72 to move horizontally through the synchronous belt. The spray gun 72 moves from one side of the bed net to the other side. During the movement, the spray gun 72 sprays glue on the side of the bed net and the upper and lower cloths. After spraying the glue, the spray gun 72 stays on the other side of the bed net to form a channel for the sponge picking and conveying device to push the picked sponge strip to the position to be bonded, thereby facilitating the improvement of the bonding efficiency.

[0089] According to the exemplary embodiment, as Figure 5 and Figure 7As shown, a bed net edge sealing device further includes a moving platform and a centering mechanism. The moving platform includes at least two power rollers 81 arranged at intervals. The power rollers 81 are rotatably connected to the frame 5 to convey the bed net in the direction close to the sponge picking and delivering device.

[0090] According to the exemplary embodiment, as Figure 5 、 Figure 7 and Figure 8 shown, the centering mechanism includes a calibration component 91 and a rotating component 92. The calibration component 91 includes a first calibration piece 911 and a second calibration piece 912. Both the first calibration piece 911 and the second calibration piece 912 are arranged at the bottom of the power roller 81 and are distributed in the gap between the power rollers 81. By moving synchronously along the gap between the power rollers 81 through the moving mechanism 10, the two sides of the bed net are jointly squeezed to correct the position of the mattress. The two ends of the bed net are aligned with the two ends of the sponge strip picked up by the sponge picking and delivering device.

[0091] For example, the first calibration piece 911 and the second calibration piece 912 can be telescopic rods. In the case of selecting telescopic rods, the number of telescopic rods can be set according to user needs, so it is not limited. The telescopic rods are vertically arranged.

[0092] According to the exemplary embodiment, as Figure 7 and Figure 8 shown, the moving mechanism 10 includes a first rack 101, a gear 102 and a second rack 103. The first rack 101 is fixedly connected to the first calibration piece 911 and is slidably connected to the frame 5. The first rack 101 meshes with the gear 102. The gear 102 is rotatably connected to the frame 5 through motor drive. The second rack 103 meshes with the gear 102. The second rack 103 is fixedly connected to the second calibration piece 912 and is slidably connected to the frame 5.

[0093] In the operation of the above implementation scheme, the motor drives the gear 102 to rotate. The gear 102 drives the first rack 101 and the second rack 103 to move relatively. The first rack 101 and the second rack 103 drive the first calibration piece 911 and the second calibration piece 912 to move towards each other to clamp the bed net. The bed net can be moved to the middle bonding position, thereby improving the bonding accuracy and further improving the production efficiency.

[0094] In the above implementation scheme, alternatively, the moving mechanism 10 can also adopt a motor-driven synchronous belt or chain drive. The first calibration piece 911 and the second calibration piece 912 are respectively connected to the loose side and the tight side of the synchronous belt or chain. When the motor drives the synchronous belt or chain to move, the first calibration piece 911 and the second calibration piece 912 move towards each other synchronously.

[0095] According to the exemplary embodiment, as Figure 8As shown in the figure, the rotating assembly 92 includes at least one telescopic cylinder 921, a connecting plate 922, a reduction motor 923, a rotating shaft 924, and a cross bracket 925. For example, there are two telescopic cylinders 921, and the two telescopic cylinders 921 are spaced apart. The telescopic cylinder 921 is vertically arranged, fixedly connected to the frame 5, and is located below the power roller 81. The movable ends of the two telescopic cylinders 921 are fixedly connected to both ends of the connecting plate 922. The reduction motor 923 is fixedly connected to the connecting plate 922. One end of the rotating shaft 924 is coaxially and fixedly connected to the output shaft of the reduction motor 923, and the other end is fixedly connected to the cross bracket 925.

[0096] In the above implementation, when the bed net is conveyed on the power roller 81, the upper surface of the cross bracket 925 is lower than the conveying surface of the power roller 81. When the bed net turns, the telescopic cylinder 921 drives the connecting plate 922 to move upward. The connecting plate 922 drives the cross bracket 925 to move upward, so that the cross bracket 925 extends above the power roller 81 to lift the bed net. The reduction motor 923 drives the rotating shaft 924 to rotate. The rotating shaft 924 drives the cross bracket 925 to rotate, so that the bed net rotates horizontally to adjust the direction of the bed net, thereby facilitating the bonding of other sides of the bed net and improving the processing efficiency.

[0097] According to one aspect of the present application, the present application provides a bed net combined production device.

[0098] A bed net combined production device includes the bed net edge sealing device and the bed net bonding device described above. The bed net bonding device includes a combined platform, a spring string feeding mechanism, a sponge strip feeding mechanism, and a bonding mechanism.

[0099] The combined platform is arranged on one side of the bed net edge sealing device to pre-install the bed net. The spring string feeding mechanism is used to cut a continuous spring string into a predetermined length and convey it onto the combined platform. The sponge strip feeding mechanism is used to convey the sponge strip to the combined platform. The bonding mechanism bonds the spring string or sponge strip located on the combined platform together to form a bed net with sponge strips at both ends and a bagged spring string in the middle.

[0100] According to the exemplary embodiment, a bed net edge sealing device further includes a docking conveying mechanism. One end of the docking conveying mechanism abuts against the output end of the bed net bonding device, and the other end is located on the bed net edge sealing device. The conveying direction of the docking conveying mechanism is perpendicular to that of the sponge picking and sending device.

[0101] The docking conveying mechanism forms a height difference with the bed net bonding device through vertical movement, transfers the installed bed net from the bed net bonding device to the bed net edge sealing device, and conveys the installed bed net in the direction of the sponge picking and sending device by the bed net edge sealing device to complete the bed net edge sealing.

[0102] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application.
