[0046] The bagged spring gluing machine is a device that lays a strip of bagged spring cut into a certain length side by side and glues the bag surface of adjacent strip-shaped bagged springs to form a bed net. The working principle of the bagged spring gluing machine is as follows: manually put the bagged spring into the turnover spring pushing mechanism, start the button, the glue spraying head of the glue spraying mechanism is driven by the glue spraying servo motor to start moving and spraying glue. When the glue spraying is completed, the turnover spring pushing mechanism first transports the strip-shaped bagged spring to one side of the bed net forming mechanism through the turnover action, and then pushes the strip-shaped bagged spring into the two-layer conveying belt between the bed net forming mechanism through the spring pushing action, while the two-layer conveying belt moves forward by one spring diameter position through the transmission of the conveying transmission assembly. The strip-shaped bagged springs and the non-woven fabric will be glued and formed. When a bed net is completed, the conveying belt will automatically move a distance, so that a gap is formed between the next bed net. When the gap moves to the cutting mechanism, the cutting mechanism will start cutting when the gap is detected by the photoelectric switch, completing the production process of a bed net.

[0047] As Figure 1 And Figure 2The illustrated bag spring gluing machine comprises a rack assembly 1 and a bed net forming mechanism 2, a spring turning mechanism 3, a glue spraying mechanism 4, a cutting mechanism 5 and a cloth winding shaft mechanism 6 installed on the rack assembly 1. The cloth winding shaft mechanism 6 is used to provide non-woven fabric to the upper and lower layers of the bed net forming mechanism 2, the glue spraying mechanism 4 is used to spray glue into the gap between the two layers of non-woven fabric, the spring turning mechanism 3 is used to push the whole row of bag springs to the bed net forming mechanism 2, and the upper and lower non-woven fabrics and the bag springs are glued and formed into a bed net on the bed net forming mechanism 2. The cutting mechanism 5 cuts the upper and lower non-woven fabrics between the adjacent two bed nets to complete the production process of a bed net.

[0048] As shown in Figure 3 and Figure 4 In this embodiment, the cloth winding shaft mechanism 6 comprises a pair of cloth winding shaft supports 61 installed on the rack assembly 1, a cloth winding shaft 62 connected between the pair of cloth winding shaft supports 61 for winding the non-woven fabric roll, and a magnetic powder clutch 63 installed on one of the cloth winding shaft supports 61 for driving the cloth winding shaft 62 to rotate. The cloth winding shaft 62 of the cloth winding shaft mechanism 6 adopts adjustable constant tension braking of the magnetic powder clutch 63. Since the magnetic powder clutch 63 has the advantage of adjustable constant tension braking, the cloth winding shaft mechanism 6 can accurately provide non-woven fabric to the bed net forming mechanism 2, ensuring the stability of the tension of the non-woven fabric during the conveying process, thereby improving the forming quality of the bed net.

[0049] Specifically, the output end of the magnetic powder clutch 63 is drivingly connected with a driving gear 64, the cloth winding shaft 62 is fixedly connected with a driven gear 65 drivingly engaged with the driving gear 64, and a gear cover 66 is further installed on the cloth winding shaft support 61 and covers the outer periphery of the driving gear 64 and the driven gear 65. The driving gear 65 is drivingly engaged with the driven gear 65 to drive the cloth winding shaft 62 to rotate, which has the advantages of good transmission stability, accurate transmission ratio, strong working reliability and long service life. Moreover, the gear cover 66 protects the driving gear 64 and the driven gear 65. The two ends of the cloth winding shaft 62 close to the cloth winding shaft support 61 are respectively fixedly connected with cloth winding shaft cone sleeves 67, and the tapered surfaces of the two cloth winding shaft cone sleeves 67 are oppositely arranged. The cloth winding shaft cone sleeves 67 limit the non-woven fabric roll wound on the cloth winding shaft 62 to prevent the non-woven fabric roll from deviating horizontally.

[0050] As shown in Figure 5 and Figure 6As shown, in this embodiment, the cutting mechanism 5 includes a fabric cutting knife assembly 51 and a fabric cutting knife power assembly that drives the fabric cutting knife assembly 51 to move horizontally. The fabric cutting knife assembly 51 includes a vertically arranged cutting guide post 511 and two pairs of electric blades 512 mounted on the cutting guide post 511. The electric blades 512 include a motor 5121 and a circular blade 5122 driven by the motor 5121 to cut the nonwoven fabric. The circular blades 5122 on the two pairs of electric blades 512 are arranged opposite to each other and cut the nonwoven fabric located in the upper and lower layers respectively. The fabric cutting knife power assembly includes a shearing chain or synchronous belt drive assembly, an upper beam assembly 54 and a lower beam assembly 55 of the fabric cutting guide shaft connected to the drive chain or synchronous belt of the shearing chain or synchronous belt drive assembly, an upper fabric cutting guide shaft assembly 53 connected to the upper beam assembly 54, and a lower fabric cutting guide shaft assembly 52 connected to the lower beam assembly 55. The cutting guide post 511 is connected to an upper cutting linear bearing assembly 513 connected to the upper cutting guide shaft assembly 53 and a lower cutting linear bearing assembly 514 connected to the lower cutting guide shaft assembly 52. ​​The fabric cutting knife assembly 51 uses a motor 5121 to drive the circular blade 5122 to rotate for cutting non-woven fabric. Compared with flat blade cutting, this method has the advantages of faster cutting speed and higher cutting efficiency.

[0051] Furthermore, both the upper linear bearing assembly 513 and the lower linear bearing assembly 514 are vertically movably connected to an upper cutter fixing seat 515. Two pairs of electric cutters 512 are respectively installed on the corresponding cutter fixing seats 515, which can realize the height adjustment between the two sets of electric cutters 512 and realize the cutting of bed nets of different thicknesses.

[0052] like Figure 7 As shown in Figure 11, the bed net forming mechanism 2 includes a first conveyor support 21 and a second conveyor support 22 arranged opposite to each other, an upper conveyor belt assembly 23 and a lower conveyor belt assembly 24 installed between the first conveyor support 21 and the second conveyor support 22, and a conveying transmission assembly 25 installed on the first conveyor support 21 for driving the upper drive shaft 231 of the upper conveyor belt assembly 23 and the lower drive shaft 241 of the lower conveyor belt assembly 24 to rotate, thereby driving the upper conveyor belt 233 and the lower conveyor belt 243 to move. The upper conveyor belt assembly 23 includes an upper drive shaft 231, an upper driven shaft 232, and an upper conveyor belt 233 sleeved between the upper drive shaft 231 and the upper driven shaft 232; the lower conveyor belt assembly 24 includes a lower drive shaft 241, a lower driven shaft 242, and a lower conveyor belt 243 sleeved between the lower drive shaft 241 and the lower driven shaft 242.

[0053] Specifically, the conveying transmission assembly 25 includes a first motor 251 mounted on the first conveying support 21, a main transmission shaft 253 driven to move by the first motor 251 and extending along the connecting direction of the upper conveying belt assembly 23 and the lower conveying belt assembly 24, an upper sprocket assembly 254 and a lower sprocket assembly 255 in transmission connection with the main transmission shaft 253, the upper sprocket assembly 254 being sleeved between the upper driving shaft 231 and the compression roller 261 located at the upper layer, and the lower sprocket assembly 255 being sleeved between the lower driving shaft 241 and the compression roller 261 located at the lower layer. One first motor 251 is used to drive the upper sprocket assembly 254 and the lower sprocket assembly 255 to move, thereby driving the upper conveying belt assembly 23, the lower conveying belt assembly 24 and the two compression rollers 261 to move. This mode has the advantages of compact structure, high transmission precision and stable operation.

[0054] In the embodiment, the first conveying support 21 of the bed net forming mechanism 2 is provided with two cut cloth tensioning devices 26, which are respectively arranged in position correspondence with the upper conveying belt assembly 23 and the lower conveying belt assembly 24. The cut cloth tensioning device 26 includes a compression roller 261, a swing arm 263 and a driving member. The compression roller 261 is mounted between the first conveying support 21 and the second conveying support 22 and located at the output side of the conveying belt assembly. The compression surface of the compression roller 261 is flush with the conveying surface of the conveying belt. The driving shaft is in transmission connection with the compression roller shaft 262 of the compression roller 261 through a sprocket assembly. One end of the swing arm 263 is in transmission connection with the compression roller shaft 262 through a one-way bearing or a ratchet wheel 268. The output end of the driving member is connected with the other end of the swing arm 263 and used to drive the swing arm 263 to rotate to drive the compression roller shaft 262 to rotate, thereby enabling the compression roller 261 to flatten the non-woven fabric output by the conveying belt. The driving member is specifically a pneumatic cylinder 265. The first conveying support 21 is fixed with a pneumatic cylinder tail pin 267. The pneumatic cylinder 265 is rotatably mounted on the pneumatic cylinder tail pin 267 about the axis line of the pneumatic cylinder tail pin 267. The output end of the pneumatic cylinder 265 is connected with the other end of the swing arm 263 through a fish-eye joint 266.

[0055] The cut cloth tensioning device 26 is used when one bed net is completed between the two-layer conveying belt assemblies. The two-layer conveying belt assemblies will automatically move a distance, so that there is a gap region without pocketed springs between the upper and lower non-woven fabrics of the adjacent two bed nets. During the movement of the gap region of the non-woven fabric from the conveying belt assembly to the cutting mechanism 5, the surface of the non-woven fabric will be uneven and wrinkled due to the change of the tension. At this time, the pneumatic cylinder of the cut cloth tensioning device 26 is started. The pneumatic cylinder 265 drives the swing arm 263 to rotate, drives the compression roller shaft 261 and the compression roller 261 to rotate by a certain angle, thereby flattening the non-woven fabric on the compression surface of the compression roller 261. Before cutting, the non-woven fabric is ensured to be in a flat state, thereby improving the forming quality of the bed net.

[0056] Specifically, the swing arm 263 has a cam shape, and the fish-eye joint 266 is connected to an outward protruding end of the swing arm 263 by a bolt.

[0057] In the embodiment, the second conveying support 22 is provided with a cloth guide plate assembly 27, which includes a cloth guide plate located on the conveying surface of the upper conveying belt 233. The upper non-woven fabric enters the compression roller 261 through the gap between the cloth guide plate and the upper conveying belt 233, which is beneficial to ensure the flatness of the non-woven fabric.

[0058] In the embodiment, the gantry assembly 1 is provided with a photoelectric switch for detecting the gap between the upper and lower non-woven fabrics. The photoelectric switch is electrically connected to the air cylinder 265 through the controller. When the photoelectric switch detects that the gap between the upper and lower non-woven fabrics is greater than a predetermined value, a first control signal is sent to the controller. The controller controls the air cylinder 265 to start according to the first control signal. The air cylinder 265 drives the compression roller 261 to rotate through the swing arm 263, so as to flatten the non-woven fabric and improve the forming quality of the bed net. When the photoelectric switch detects that the gap between the upper and lower non-woven fabrics is equal to the predetermined value, a second control signal is sent to the controller. The controller controls the cutting mechanism 5 to start according to the second control signal. The cutting mechanism 5 starts to cut, and the process of making a bed net is completed.

[0059] In the embodiment, the bed net forming mechanism 2 further includes a lifting assembly 28 installed on the second conveying support 22. The lifting assembly 28 includes a second motor 281, a second speed reducer 282 connected to the output end of the second motor 281 and installed on the second conveying support 22, a third speed reducer 284 connected to the second speed reducer 282 through a second transmission shaft 283 and installed on the first conveying support 21, and a lead screw 285 connected to the second speed reducer 282 and the third speed reducer 284. The lead screw 285 is connected to a lifting frame 286 which moves up and down in the axial direction of the lead screw 285 through a nut seat. The upper conveying belt assembly 23 is installed between a pair of lifting frames 286. The second motor 281 can synchronously drive a pair of lead screws 285 to move, so as to drive a pair of lifting frames 286 to move vertically, thereby adjusting the distance between the upper conveying belt assembly 23 and the lower conveying belt assembly 24, so as to adapt to the production requirements of bed nets with different thicknesses. The compression roller 261 corresponding to the upper conveying belt assembly 23 and the air cylinder are also installed on the lifting frame 286, so as to meet the height adjustment requirements of the compression roller 261, and make the overall structure more compact.
