[0036] The present application designs a bagged spring string production machine. The bagged spring string production machine transports a cushioning material and compressed springs into a cloth bag, and encapsulates the cushioning material and the springs in the cloth bag. The cushioning material and the springs are combined to form a composite elastic unit, thereby obtaining a bagged spring string with a composite elastic function. Among them, the cushioning material is sponge.

[0037] Taking the direction parallel to the spring transportation as the longitudinal direction, the X direction in the figure is the longitudinal direction, and taking the direction parallel to the width of the cloth bag as the transverse direction, the Y direction in the figure is the transverse direction.

[0038] The bagged spring string production machine includes a bagged spring conveying mechanism 1000, a spring feeding mechanism 2000, a cotton filling mechanism 3000, and a welding mechanism 4000. Along the conveying direction of the cloth bag, the spring feeding mechanism 2000 is located upstream of the bagged spring conveying mechanism 1000, the cotton filling mechanism 3000 is located upstream of the bagged spring conveying mechanism 1000, and the welding mechanism 4000 is located downstream of the bagged spring conveying mechanism 1000.

[0039] Further, the cotton filling mechanism 3000 and the spring feeding mechanism 2000 are distributed at intervals in the transverse direction. The spring feeding mechanism 2000 is used to convey the springs in a compressed state along the longitudinal direction, the cotton filling mechanism 3000 is used to fill the cushioning material into the cloth bag, the bagged spring conveying mechanism 1000 is used to convey the springs and the cushioning material in the cloth bag, and the welding mechanism 4000 is used to form a transverse weld on the cloth bag to encapsulate the springs and the cushioning material in an independent bag chamber, obtaining a bagged spring string with a cushion.

[0040] It can be understood that the end parts of the spring feeding mechanism and the cotton stuffing mechanism 3000 are wrapped in a cloth bag. The spring feeding mechanism 2000 longitudinally conveys the compressed spring into the cloth bag, and at the same time, the cotton stuffing mechanism 3000 longitudinally fills the cushioning material into the cloth bag. The bagged spring conveying mechanism 1000 then longitudinally conveys the spring and the cushioning material in the cloth bag to the welding mechanism 4000, and the welding mechanism 4000 welds a transverse weld on the cloth bag. Specifically, the bagged spring conveying mechanism 1000 is used to separate the spring from the spring feeding mechanism 2000 and enter the cloth bag, and separate the cushioning material from the cotton stuffing mechanism 3000 and enter the cloth bag, and is used to restrict the spring from bouncing in the cloth bag during the conveying process.

[0041] The cotton stuffing mechanism 3000 includes a cotton feeding assembly 3100 and a cotton cutting assembly 3200. The cotton feeding assembly 3100 is used to longitudinally convey the cushioning material, and the cushioning material conveyed by the cotton feeding assembly 3100 is a continuous sponge strip. The cotton cutting assembly 3200 is located at the outlet of the cotton feeding assembly 3100, and the cotton cutting assembly 3200 is used to cut off the cushioning material, and the cushioning material is cut into independent cushion blocks. It can be understood that under the conveyance of the cotton feeding assembly 3100, the cut cushioning material is filled into the cloth bag.

[0042] It should be noted that at least one end of the spring in the cloth bag is filled with the cushioning material. Correspondingly, at least one of the two longitudinal side edges of the cloth bag is provided with the cotton stuffing mechanism 3000.

[0043] In some embodiments, the cotton stuffing mechanism 3000 includes a cotton stuffing mounting seat 3301. The cotton feeding assembly 3100 is connected to the cotton stuffing mounting seat 3301. The cotton cutting assembly 3200 includes a cutter 3201 and a cutter seat 3202. The cutter 3201 and the cutter seat 3202 are arranged on the cotton stuffing mounting seat 3301, and at least one of the cutter 3201 and the cutter seat 3202 can move so that the cutter 3201 and the cutter seat 3202 approach each other, thereby cutting off the cushioning material. It can be understood that the cotton cutting assembly 3200 includes a cotton cutting driver 3203, and the cotton cutting driver 3203 is arranged on the cotton stuffing mounting seat 3301.

[0044] Furthermore, driven by the cotton cutting driver 3203, the cutter 3201 and the cutter seat 3202 move transversely at the same time. Specifically, the cotton cutting assembly 3200 includes a rotary transmission structure, and the rotary transmission structure is connected to the rotating shaft of the cotton cutting driver 3203. It can be understood that driven by the cotton cutting driver 3203, the rotary transmission structure rotates around its own rotation center, and the rotary transmission structure drives the cutter 3201 and the cutter seat 3202 to approach each other and cut off the cushioning material.

[0045] Specifically, the rotary drive structure includes a wheel disc. There are two drive columns 3204 provided on the rotary drive structure. The drive columns 3204 are located on the surface of the wheel disc. The two drive columns 3204 are at eccentric positions on the rotary drive structure, and the positions of the two drive columns 3204 are symmetrically distributed about the rotation center of the rotary drive structure. It can be understood that the cutter 3201 is movably connected to one of the drive columns 3204, and the cutter holder 3202 is movably connected to the other drive column 3204. In this case, the cutter 3201 and the cutter holder 3202 share a cotton cutting driver 3203, and the cutter 3201 and the cutter holder 3202 can move closer to or away from each other synchronously.

[0046] Of course, the cotton cutting driver 3203 can also be designed such that the cutter 3201 and the cutter holder 3202 are respectively provided with a cotton cutting driver 3203. In this case, there are two rotary drive structures. The cutter 3201 is connected to the drive column 3204 of one rotary drive structure, and the cutter holder 3202 is connected to the drive column 3204 of the other rotary drive structure.

[0047] It should be noted that under the drive of the cotton cutting driver 3203, the rotary drive structure rotates itself, and the drive column 3204 moves along a circumference around the center of the rotary drive structure, so that the drive column 3204 drives the cutter 3201 or the cutter holder 3202 to move.

[0048] Furthermore, the cutter 3201 and the cutter holder 3202 are both provided with an activity groove 3205. The drive column 3204 extends into the activity groove 3205, thereby realizing the movable connection between the drive column 3204 and the cutter 3201 and between the drive column 3204 and the cutter holder 3202. It can be understood that when the rotary drive structure rotates, the drive column 3204 moves in the activity groove 3205 and drives the cutter 3201 or the cutter holder 3202 to move.

[0049] Regarding the rotary drive structure, it can be at least alternatively designed as follows: The rotary drive structure includes a swing arm, and the drive columns 3204 are arranged at both ends on the side surface of the swing arm. Or, the rotary drive structure includes a cam. In this case, the cam has a drive column 3204 or the cam does not have a drive column 3204.

[0050] In some examples, to enable the cutter 3201 or the cutter holder 3202 to move smoothly, the cotton cutting assembly 3200 includes a cotton cutting guiding structure 3206. The cotton cutting guiding structure 3206 is arranged on the cotton filling mounting base 3301. The cutter 3201 or the cutter holder 3202 is movably connected to the cotton cutting guiding structure 3206, and the cotton cutting guiding structure 3206 extends horizontally.

[0051] Specifically, the cotton cutting guiding structure 3206 is set as a guide rod. It can be understood that the cotton cutting guiding structure 3206 can be at least alternatively designed as: the cotton cutting guiding structure 3206 is set as a guide rail; or, the cotton cutting guiding structure 3206 is set as a chute on the cotton filling mounting seat 3301.

[0052] It should be noted that regarding the way the cotton cutting assembly 3200 drives the movement of the cutting knife 3201 and the cutting knife seat 3202, there are at least the following alternative ways: the cotton cutting assembly 3200 drives the cutting knife 3201 or the cutting knife seat 3202 to move with an electric push rod. Or, the cotton cutting assembly 3200 drives the cutting knife 3201 or the cutting knife seat 3202 to move in the way of a lead screw pair. Or, the cotton cutting assembly 3200 drives the cutting knife 3201 or the cutting knife seat 3202 to move with a gear-rack mechanism. Or, the cotton cutting assembly 3200 drives the cutting knife 3201 or the cutting knife seat 3202 to move in the way of belt drive. Or, the cotton cutting assembly 3200 drives the cutting knife 3201 or the cutting knife seat 3202 to move in the way of hydraulic drive or cylinder drive.

[0053] In some embodiments, the cotton feeding assembly 3100 includes a second conveying channel that extends longitudinally. During the process of conveying the long strip of cushioning material through the second conveying channel, the cotton cutting assembly 3200 cuts the long strip of cushioning material to obtain cushioning blocks.

[0054] Specifically, the cotton feeding assembly 3100 includes two cotton feeding conveying members 3101 that are spaced apart transversely. The two cotton feeding conveying members 3101 form a second conveying channel by being spaced apart transversely. The cotton feeding conveying members 3101 extend longitudinally, and the cotton feeding conveying members 3101 convey the cushioning material longitudinally, and the cushioning material is in a compressed state under the action of the two cotton feeding conveying members 3101.

[0055] In some examples, the cotton feeding conveying member 3101 includes a conveyor belt, and the conveyor belts of the two cotton feeding conveying members 3101 run synchronously, and the cushioning material is squeezed during the conveying process of the two conveyor belts.

[0056] In some examples, the cotton feeding assembly 3100 includes a baffle 3102. The baffle 3102 is arranged on the upper side of the cotton feeding assembly 3100, the baffle 3102 extends longitudinally, and the baffle 3102 and the two cotton feeding conveying members 3101 enclose to form a second conveying channel.

[0057] In some embodiments, the spring feeding mechanism 2000 includes a first conveying channel 2100 that extends longitudinally. The first conveying channel 2100 is used to convey a spring longitudinally into a cloth bag. During the process of conveying the spring through the first conveying channel 2100, the spring remains in a compressed state.

[0058] Specifically, the spring feeding mechanism 2000 includes two spring feeding conveyors spaced apart transversely. The two spring feeding conveyors form a first conveying channel 2100 with a transverse spacing. The spring feeding conveyors extend longitudinally. The spring feeding conveyors convey the spring longitudinally, and the spring is in a compressed state under the action of the two spring feeding conveyors.

[0059] In some examples, the spring feeding conveyor includes a conveyor belt or a conveyor chain.

[0060] In some embodiments, the spring feeding mechanism 2000 includes a partition plate disposed in the first conveying channel 2100 and extending longitudinally. During the conveying of the compressed spring in the first conveying channel 2100, the partition plate is used to separate the steel wires of the spring to prevent the steel wires from being intertwined during the conveying process and to prevent the spring from not being able to unfold in the cloth bag.

[0061] It should be noted that the partition plate is disposed between the two spring feeding conveyors in an upright state. Further, the partition plate is provided as at least one.

[0062] In some embodiments, the spring feeding mechanism 2000 includes a pushing component 2200 for pushing the compressed spring longitudinally into the cloth bag. Specifically, the pushing component 2200 includes a spring pushing member 2201 that moves longitudinally and can reciprocate.

[0063] It can be understood that the pushing component 2200 includes a pushing drive component 2202 connected to the spring pushing member 2201. Under the drive of the pushing drive component 2202, the spring pushing member 2201 reciprocates longitudinally.

[0064] It should be noted that the pushing drive component 2202 drives the spring pushing member 2201 to move with a crank-slider mechanism. Of course, there are at least the following alternative ways: the pushing drive component 2202 drives the spring pushing member 2201 to move with an electric push rod. Or, the pushing drive component 2202 drives the spring pushing member 2201 to move in the manner of a screw pair. Or, the pushing drive component 2202 drives the spring pushing member 2201 to move with a gear-rack mechanism.

Or, the pushing drive component 2202 drives the spring pushing member 2201 to move in the manner of hydraulic transmission or cylinder transmission.

[0065] Further, the spring feeding mechanism 2000 includes a compression component 2300 for squeezing the two ends of the spring transversely to compress the spring. In this case, in the spring feeding mechanism 2000, the compression component 2300 first compresses the spring, and then the pushing component 2200 pushes the compressed spring into the first conveying channel 2100.

[0066] Specifically, the compression assembly 2300 includes two compression spring members 2301 that can approach each other laterally. Further, at least one compression spring member 2301 can move laterally. In some examples, the compression spring member 2301 is provided as a pressing plate.

[0067] It can be understood that the compression assembly 2300 includes a compression driving assembly for driving the compression spring member 2301 to reciprocate laterally. Specifically, the compression driving assembly drives the compression spring member 2301 to move in a belt drive manner.

[0068] Regarding the structure of the compression driving assembly, at least it can also be alternatively designed as: the compression driving assembly drives the compression spring member 2301 to move with an electric push rod. Or, the compression driving assembly drives the compression spring member 2301 to move in a lead screw pair manner. Or, the compression driving assembly drives the compression spring member 2301 to move with a rack and pinion mechanism. Or, the compression driving assembly drives the compression spring member 2301 to move in a hydraulic transmission or cylinder transmission manner.

[0069] In some examples, the compression assembly 2300 includes a compression guiding structure, and the compression spring member 2301 is movably connected to the compression guiding structure, and the compression spring member 2301 reciprocates laterally on the compression guiding structure.

[0070] Specifically, the compression assembly 2300 includes a limit seat 2302, and the compression guiding structure is arranged on the limit seat 2302. Further, the compression guiding structure is formed as a sliding groove in the limit seat 2302, and the side wall of the sliding groove can prevent the spring from shifting during the spring compression process.

[0071] Regarding the compression guiding structure, at least it can also be alternatively designed as: the compression guiding structure is provided as a guide rod or a guide rail.

[0072] It should be noted that the spring pushing member 2201 can pass through the limit seat 2302 longitudinally to push out the compressed spring from the limit seat 2302. Specifically, an avoidance area is provided on the side wall of the limit seat 2302, and the avoidance area penetrates the side wall of the limit seat 2302 longitudinally, and the avoidance area is formed as an opening on the side wall of the limit seat 2302.

[0073] In some embodiments, the spring feeding mechanism 2000 includes a transfer assembly 2400 for transferring the spring between the two compression spring members 2301 so that the compression spring members 2301 can squeeze the spring.

[0074] Specifically, the transfer assembly 2400 includes a first magnetic attraction seat 2401 that can be lifted and lowered. The first magnetic attraction seat 2401 is used to capture the spring, and the first magnetic attraction seat 2401 can descend and transfer the spring between the two compression spring members 2301.

[0075] In some embodiments, the bagged spring string production machine includes a spring conveying mechanism 5000. The spring conveying mechanism 5000 includes a conveyor chain and a plurality of second magnetic suction seats, and each second magnetic suction seat is spaced apart on the conveyor chain. The transfer assembly 2400 grabs the spring on the second magnetic suction seat through the first magnetic suction seat 2401.

[0076] In some embodiments, the bagged spring conveying mechanism 1000 includes a limiting conveying assembly 1100. After the compressed spring is loaded into the cloth bag, the limiting conveying assembly 1100 can limit the spring in the cloth bag and convey the spring forward longitudinally. Under the action of the limiting conveying assembly 1100, the spring is restricted in the cloth bag, thereby avoiding the position deviation of the spring in the cloth bag. On the other hand, the limiting conveying assembly 1100 can also prevent the spring in the cloth bag from deforming.

[0077] Further, the limiting conveying assembly 1100 includes two limiting assemblies 1101. The two limiting assemblies 1101 are arranged at intervals in the vertical direction, and the two limiting components can approach or move away from each other in the vertical direction. The cloth bag passes through between the two limiting assemblies 1101. One of the limiting assemblies 1101 is located on the upper side of the cloth bag, and the other limiting assembly 1101 is located on the lower side of the cloth bag. When the two limiting assemblies 1101 approach each other, they can limit the spring in the cloth bag to prevent the spring from shifting or deforming.

[0078] Specifically, the two limiting assemblies 1101 of the limiting conveying assembly 1100 are respectively located on the upper and lower sides of the end of the spring feeding assembly. When the two limiting assemblies 1101 of the limiting conveying assembly 1100 approach each other in the vertical direction and move longitudinally, so that the spring disengages from the spring feeding mechanism 2000 and reaches the welding position of the welding mechanism 4000, and during the process that the spring disengages from the spring feeding assembly, bounces in the cloth bag, reaches the welding position of the welding mechanism 4000, and until the spring is encapsulated, the spring is in the limiting area.

[0079] The limiting assembly 1101 includes at least two pressing arms 1102. The same ends of the pressing arms 1102 are cantilevered, the pressing arms 1102 extend horizontally, and the pressing arms 1102 are arranged at intervals longitudinally. It should be noted that the pressing arms 1102 in the two limiting assemblies 1101 are paired.

[0080] It can be understood that when the two limiting assemblies 1101 approach each other, two adjacent pressing arms 1102 in one limiting assembly 1101 and the corresponding two pressing arms 1102 in the other limiting assembly 1101 form a limiting area for restricting the spring in the cloth bag. Specifically, among the four pressing arms 1102, one pair of pressing arms 1102 is located upstream of the spring, and the other pair of pressing arms 1102 is located downstream of the spring.

[0081] It should be noted that when the two limiting components 1101 approach each other, the distance between the two pressing arms 1102 spaced in the vertical direction is smaller than the diameter of the spring in the cloth bag, so that the four pressing arms 1102 can limit the spring and jointly confine the spring in the cloth bag.

[0082] Furthermore, the limiting components 1101 can move synchronously back and forth in the longitudinal direction, and when the limiting components 1101 move forward in the longitudinal direction, the spring can move in the longitudinal direction. Specifically, when the two limiting components 1101 move forward in the longitudinal direction, the two pressing arms 1102 located upstream of the spring push the spring forward, so that the spring moves forward in the cloth bag. It can be understood that when the two limiting components 1101 approach each other, at least the two pressing arms 1102 located upstream of the spring can abut against the spring.

[0083] In some examples, when the two limiting components 1101 approach each other, the two pressing arms 1102 located upstream of the spring abut against the spring. In other examples, when the two limiting components 1101 approach each other, both the two pressing arms 1102 located upstream of the spring and the two pressing arms 1102 located downstream of the spring abut against the spring.

[0084] It can be understood that in order to enable the pressing arm 1102 to push the spring to move in the cloth bag, the pressing arm 1102 is in a virtual contact with the surface of the cloth bag, and there is a loose clamping state between the pressing arm 1102 and the cloth bag. In this case, when the two limiting components 1101 approach each other, the pressing arm 1102 does not clamp the cloth bag, so that the pressing arm 1102 can move smoothly on the surface of the cloth bag.

[0085] It should be noted that when the limiting component 1101 includes at least three pressing arms 1102, the limiting component 1101 can simultaneously limit and convey multiple springs in the cloth bag.

[0086] In some embodiments, the distance between two adjacent pressing arms 1102 in the limiting component 1101 can be adjusted to adapt to springs with different waist diameters.

[0087] Specifically, the limiting component 1101 includes a first mounting seat 1103, the pressing arm 1102 is arranged on the first mounting seat 1103, and the pressing arm 1102 can move longitudinally on the first mounting seat 1103 to adjust its position.

[0091] In other alternative embodiments, the first mounting seat 1103 is provided with a guide rod extending longitudinally.

[0092] In some embodiments, the limit conveying assembly 1100 includes a first driving assembly 1300. The first driving assembly 1300 is disposed upstream or downstream of the limit assembly 1101. Driven by the first driving assembly 1300, the two limit assemblies 1101 can reciprocate synchronously in the longitudinal direction.

[0093] Specifically, the first driving assembly 1300 includes a first rotating structure 1301 and a first connecting rod 1302. One end of the first connecting rod 1302 is hinged to the eccentric position of the first rotating structure 1301, and the other end of the first connecting rod 1302 is hinged to the limit conveying assembly 1100. It can be understood that the first rotating structure 1301, the first connecting rod 1302 and the limit conveying assembly 1100 form a crank-slider mechanism.

[0094] It can be understood that the first driving assembly 1300 includes a first driver 1303. The first driver 1303 includes a motor.

[0106] In some embodiments, the limiting conveying assembly 1100 includes at least one second driving assembly 1400, and both limiting assemblies 1101 are connected to the second driving assembly 1400. It can be understood that under the drive of the second driving assembly 1400, the two limiting assemblies 1101 approach or move away from each other.

[0107] Specifically, the limiting conveying assembly 1100 configures a common second driving assembly 1400 for the two limiting assemblies 1101, so that the two limiting assemblies 1101 approach or move away from each other synchronously. Or, the limiting conveying assembly 1100 configures second driving assemblies 1400 for the two limiting assemblies 1101 respectively.

[0108] In some embodiments, the second driving assembly 1400 includes a second rotating structure 1401 and a second connecting rod 1402. One end of the second connecting rod 1402 is articulated at the eccentric position of the second rotating structure 1401, and the other end of the second connecting rod 1402 is articulated with the limiting assembly 1101.

It can be understood that the second rotating structure 1401, the second connecting rod 1402 and the limiting assembly 1101 form a crank-slider mechanism.

[0109] It can be understood that the second driving assembly 1400 includes a second driver, and the second driver is arranged on the second mounting seat 1201. Further, the second driver includes a motor, and the second driver drives the second rotating structure 1401 to rotate, and then the second rotating structure 1401 drives the limiting assembly 1101 to move through the connecting rod.

[0110] It should be noted that in some examples, two limiting assemblies 1101 share one second driving assembly 1400, then the second connecting rods 1402 of the second driving assembly 1400 are arranged in two, and the hinged positions of the two second connecting rods 1402 on the second rotating structure 1401 are symmetrically distributed about the rotation center of the second rotating structure 1401, so that the second rotating structure 1401 drives the two limiting assemblies 1101 to approach or move away from each other through the two second connecting rods 1402. In other examples, two limiting assemblies 1101 are respectively configured with a second driving assembly 1400, then the second connecting rod 1402 of the second driving assembly 1400 is arranged in one.

[0111] In some examples, the second rotating structure 1401 is arranged as a disc, the disc is connected to the rotating shaft of the second driver, and the hinged position of the second connecting rod 1402 and the second rotating structure 1401 is on the side surface of the disc and deviates from the rotation center on the disc.

[0112] Regarding the second rotating structure 1401, there are at least the following alternative embodiments.

[0113] In some alternative embodiments, the second rotating structure 1401 is arranged as a sector wheel.

[0114] In other alternative embodiments, the second rotating structure 1401 is arranged as a swing arm, and the second connecting rod 1402 is hinged to the end of the swing arm. When two limiting assemblies 1101 share one second driving assembly 1400, the middle of the swing arm is arranged on the rotating shaft of the second driver. When two limiting assemblies 1101 are respectively configured with a second driving assembly 1400, the other end of the swing arm is arranged on the rotating shaft of the second driver.

[0115] Regarding the structure of the second driving assembly 1400, there are at least the following alternative ways: the second driving assembly 1400 includes a hydraulic cylinder or a linear motor or a rack and pinion mechanism or a belt drive mechanism or a lead screw pair mechanism.

[0116] In some examples, the limiting conveying assembly 1100 includes a second guiding structure 1203, and the first mounting seat 1103 of the limiting assembly 1101 is movably arranged on the second guiding structure 1203. Under the guidance of the second guiding structure 1203, the second driving assembly 1400 drives the two limiting assemblies 1101 to approach or move away from each other.

[0117] Specifically, the second guiding structure 1203 includes a guide rail, and the first mounting seat 1103 is movably arranged on the guide rail through a slider.

[0118] Regarding the second guiding structure 1203, there are at least the following alternative embodiments.

[0119] In some alternative embodiments, the second guiding structure 1203 includes a guide groove.

[0120] In some other alternative embodiments, the second guiding structure 1203 includes a guide rod.

[0121] In some embodiments, the limiting conveying assembly 1100 is provided with at least two, and the limiting conveying assemblies 1100 are distributed at intervals in the lateral direction on both sides of the cloth bag.

[0122] Specifically, a limiting conveying assembly 1100 is arranged on one longitudinal side of the cloth bag, and a limiting conveying assembly 1100 is also arranged on the other longitudinal side of the cloth bag. It can be understood that the second mounting seats 1201 of the limiting conveying assemblies 1100 on both sides are distributed at intervals in the lateral direction, and the area between the second mounting seats 1201 is the conveying channel of the cloth bag in the longitudinal direction, and the second mounting seats 1201 are respectively located on both sides of the cloth bag.

[0123] It should be noted that the actions of the limiting components 1101 of the limiting conveying assemblies 1100 on both sides of the cloth bag approaching each other are carried out alternately, and the actions of the limiting conveying assemblies 1100 on both sides of the cloth bag moving the springs longitudinally are carried out alternately. Specifically, on both sides of the cloth bag, the limiting components 1101 of the limiting conveying assembly 1100 on one side approach each other and then move longitudinally, while the limiting components 1101 of the limiting conveying assembly 1100 on the other side move away from each other and then move longitudinally in the reverse direction. The limiting conveying assemblies 1100 on both sides of the cloth bag move in such a cycle, so as to realize the forward conveying of the springs in the cloth bag.

[0124] It can be understood that on both sides of the cloth bag, the limiting components 1101 of the limiting conveying assembly 1100 on one side approach each other and then move forward longitudinally, while the limiting components 1101 of the limiting conveying assembly 1100 on the other side move away from each other and move backward longitudinally. In this case, at the end of the spring feeding assembly, the limiting conveying assemblies 1100 alternately hold, so as to limit the position of the springs in the cloth bag, and convey the springs into the cloth bag one by one, and convey the springs to the welding position one by one.

[0125] The bagged spring conveying mechanism 1000 and the limiting conveying components 1100 on both sides of the cloth bag can move alternately longitudinally, and the limiting components 1101 in the limiting conveying components 1100 on both sides of the cloth bag can approach or move away from each other alternately vertically, so that when the spring is sent out from the spring feeding component, there is more time rhythm to fully unfold the spring, and the spring can maintain a stable state in the cloth bag for packaging and welding. Furthermore, the failure rate of the clamped spring is reduced, and the operation efficiency of the equipment is improved.

[0126] In some examples, the first driving components 1300 respectively configured on both sides of the cloth bag share a power source. Specifically, a transmission shaft is arranged between the first driving components 1300 on both sides. The transmission shaft extends horizontally. The first rotating structures 1301 of the first driving components 1300 are all arranged on the transmission shaft. The transmission shaft is connected to the rotating shaft of the first driver 1303, and the transmission shaft can rotate along the central axis in its own length direction, so that the two first driving components 1300 operate synchronously.

[0127] It should be noted that the welding mechanism 4000 includes a welding head and a welding knife, and the welding head and the welding knife can approach or move away from each other. Specifically, the welding head and the welding knife approach each other and are separated to package the spring. When the limiting conveying component 1100 conveys the spring in the cloth bag longitudinally to the position of the welding mechanism 4000, the two limiting components 1101 move away from each other, and at the same time, the welding head and the welding knife of the welding mechanism 4000 approach each other, so as to complete the welding of the transverse weld on the cloth bag.

[0128] In some embodiments, the welding mechanism 4000 can move back and forth longitudinally. When the welding mechanism 4000 clamps the cloth bag, it can move forward longitudinally and drive the cloth bag to move forward longitudinally.

[0129] When the welding mechanism 4000 moves forward, another limiting conveying component 1100 conveys the next spring in the cloth bag forward to the welding position.

Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
