Description

Technical Field

[0001] This utility model relates to the field of spring bed wire mesh production technology, and in particular to a spring stringing device. Background Technology

[0002] In the field of spring mattress production, the spring-stringing equipment is the core equipment for connecting springs with transverse spring wires to form the overall structure of the mattress. Its performance directly affects the assembly accuracy and production efficiency of the mattress. Currently, spring-stringing equipment on the market typically includes a basic frame and a spring-stringing mechanism. The worktable supports the spring mattress to be processed, and the spring-stringing mechanism includes a spring-feeding seat. The formed spring wires pass through the spring-feeding seat and then into the spring mattress. Although some equipment is equipped with clamping components for positioning the spring wires, these components are mostly fixed rigid clamps that can only provide preliminary positioning for spring wires of specific specifications. Because existing spring-stringing equipment lacks a dedicated automatic moving drive mechanism, the feeding process of the spring mattress relies on manual assistance. Operators need to use a tooling lever to push the spring mattress forward. This operation method is prone to uneven manual force and inconsistent moving speed, leading to misalignment of the springs in the spring mattress, which in turn causes the corresponding positions of the spring wires and springs to deviate, resulting in problems such as missing or incorrect stringing, seriously affecting the quality and efficiency of spring stringing.

The shaping groove is connected to the inlet hole, and the wire can enter the shaping groove to form a spiral spring wire. The winding seat also has a spring outlet end near the clamp assembly, and a spring outlet hole inside the spring outlet end is connected to the winding core.

[0012] As an improvement to the above solution, the infeed assembly further includes a yarn-forming wheel and a yarn-forming drive unit that is pulsatingly connected to the yarn-forming wheel. There are two yarn-forming wheels, which are disposed between the outlet end and the infeed end. The yarn-forming drive unit can drive the yarn-forming wheels to rotate. The side of the yarn-forming wheel is provided with a pressure groove, which surrounds the side wall of the yarn-forming wheel. After the yarn passes through the outlet end, it enters the pressure groove between the two yarn-forming wheels. The yarn-forming wheel rotates to shape the yarn.

[0013] As an improvement to the above solution, the driving mechanism includes a clamping drive component, a cam, a clamping drive shaft, and a drive bearing. The clamping drive component is connected to the clamping drive shaft. The drive bearing is located inside the clamping seat. The clamping drive shaft passes through the drive bearing and is connected to the cam. The clamping drive shaft can drive the cam to rotate. The swinging mechanism includes a swing rod. The cam can drive the swing rod to swing. The clamping mechanism includes a movable seat. One end of the swing rod is connected to the movable seat. When the cam drives the swing rod to swing, the swing rod can drive the movable seat to move relative to the clamping seat. The movable seat and the clamping seat form the limiting space.

[0014] As an improvement to the above solution, the spring-feeding device further includes a spring-pushing assembly.

[0016] Implementing this utility model has the following beneficial effects: This utility model of a spring coiling device includes a feeding space, a wire pulling assembly, a wire feeding assembly, a clamping assembly, and a worktable mounted on a frame. The wire pulling assembly includes a wire pulling drive and a wire pulling block, with the drive connected to the block. The wire feeding assembly includes a wire feeding seat and a winding seat. The clamping assembly includes a clamping seat and a drive mechanism, a swing mechanism, and a clamping mechanism mounted on the seat. The wire pulling drive drives the wire pulling block to move relative to the worktable, automatically moving the spring coiling mesh from the feeding space to the worktable without manual intervention using a tooling swing arm. The wire feeding seat feeds the wire into the winding seat, which winds the wire into a spring coiling wire and then feeds it into the worktable. The spring wire is fed into the worktable, and the direction of movement of the spring wire is perpendicular to the direction of movement of the spring bed mesh, which ensures the stability of the spring wire conveying path. The drive mechanism is connected to the swing mechanism, and the swing mechanism is connected to the clamping mechanism. The drive mechanism drives the clamping mechanism to move closer to or away from the clamping seat through the swing mechanism to form a limiting space. The spring wire passes through the limiting space, which can adaptively limit the movement of the spring wire. This realizes automatic feeding of the spring bed mesh, avoids spring misalignment caused by uneven manual force and inconsistent movement speed, and ensures accurate correspondence between the spring wire and the spring of the spring bed mesh, reducing the problems of missing or misaligned spring wires, and improving the quality and efficiency of spring wire feeding.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0019] See Figure 1 and Figure 2 This utility model discloses a spring-stringing device for stringing springs 9 in a spring bed net. It includes a frame 1, a feeding space 11 mounted on the frame 1, a net-pulling assembly 2, a wire-feeding assembly 3, a clamping assembly 4, and a worktable 7. The feeding space 11 allows the spring bed net to enter the device, and its design provides a clear feeding path for the spring bed net, preventing deviation during feeding. The spring bed net enters from the feeding space 11. The net-pulling assembly 2 drives the spring bed net to move from the feeding space 11 to the worktable 7. The wire-feeding assembly 3 and the clamping assembly 4 string the springs 9 together.

[0020] See Figure 3 The mesh-pulling assembly 2 includes a mesh-pulling drive component 21 and a mesh-pulling block 22. The mesh-pulling drive component 21 is tractively connected to the mesh-pulling block 22, and the mesh-pulling drive component 21 can drive the mesh-pulling block 22 to move relative to the worktable 7 to push the spring 9 mesh. During operation, the mesh-pulling drive component 21 outputs power and drives the mesh-pulling block 22 to move relative to the worktable 7. The mesh-pulling block 22 directly contacts the spring 9 mesh and pushes it to move. Compared with the prior art, which relies on the operator to push the spring 9 mesh through a tooling lever, this method can avoid the misalignment of the springs 9 in the mesh caused by uneven manual force and inconsistent moving speed, ensuring the positional stability of the spring 9 mesh during movement and providing a prerequisite for the precise docking of the subsequent spring wire 8 and spring 9.

[0021] Referring to Figure 4, the wire feeding assembly 3 is located on the side of the worktable 7. The wire feeding assembly 3 includes a wire feeding seat 31 and a winding seat 32. The wire feeding seat 31 feeds the wire into the winding seat 32, and the winding seat 32 winds the wire into a spring wire 8 and feeds it into the worktable 7. The moving direction of the spring wire 8 is perpendicular to the moving direction of the spring bed 9. During operation, the wire feeding seat 31 stably feeds the wire into the winding seat 32, and the winding seat 32 winds the wire to form the spring wire 8 that meets the requirements of the spring bed. Then, the spring wire 8 is accurately fed into the worktable 7. At the same time, the perpendicularity between the moving direction of the spring wire 8 and the moving direction of the spring bed 9 allows the spring wire 8 to form a perpendicular and staggered docking relationship with the spring bed 9 that has moved to the worktable 7, ensuring that the spring wire 8 can be connected in series with the spring 9 of the spring bed 9.

[0022] See Figure 6 and Figure 7 The clamp assembly 4 is used to limit the spring wire 8 to ensure that it is precisely connected with the spring 9 of the spring bed net. The clamp assembly 4 includes a clamp seat 41 and a drive mechanism 42, a swing mechanism 43 and a clamping mechanism 44 disposed on the clamp seat 41. The drive mechanism 42 is connected to the swing mechanism 43, and the swing mechanism 43 is connected to the clamping mechanism 44. The drive mechanism 42 can drive the clamping mechanism 44 to move closer to or away from the clamp seat 41 through the swing mechanism 43 to form a limiting space 45. The spring wire 8 can pass through the limiting space 45 and be connected to the spring 9 of the spring bed net in a spring-spring connection.

[0023] During operation, the drive mechanism 42 outputs power and transmits it to the swing mechanism 43. The swing mechanism 43, through its own swinging motion, drives the clamping mechanism 44 to move closer to or away from the clamping seat 41, thereby forming an adjustable limiting space 45. The spring wire 8 can pass through the limiting space 45 and connect with the spring 9 of the spring bed. Through the cooperation of the drive mechanism 42 and the swing mechanism 43, the limiting space 45 is dynamically limited. This clamping assembly 4 can adapt to different specifications of the spring wire 8, forming a stable and precise limit, preventing the spring wire 8 from shifting during the spring connection process, and reducing problems such as missed connections and incorrect connections.

[0024] The beneficial effects of this utility model embodiment are as follows: This utility model embodiment of the spring coiling device includes a feeding space 11, a wire pulling assembly 2, a wire feeding assembly 3, a clamping assembly 4, and a worktable 7, all mounted on a frame 1. The wire pulling assembly 2 includes a wire pulling drive 21 and a wire pulling block 22, with the drive 21 and block 22 being convexly connected. The wire feeding assembly 3 includes a wire feeding seat 31 and a winding seat 32. The clamping assembly 4 includes a clamping seat 41 and a drive mechanism 42, a swing mechanism 43, and a clamping mechanism 44 mounted on the seat 41. The wire pulling drive 21 drives the wire pulling block 22 to move relative to the worktable 7, automatically moving the spring coiling bed from the feeding space 11 to the worktable 7 without manual intervention using a tooling swing arm. The wire feeding seat 31 feeds the wire into the winding seat 32, which then... The wire is wound into a spring wire 8 and fed into the worktable 7. The moving direction of the spring wire 8 is perpendicular to the moving direction of the spring bed mesh 9, which can ensure the stability of the conveying path of the spring wire 8. The drive mechanism 42 is connected to the swing mechanism 43, and the swing mechanism 43 is connected to the clamping mechanism 44. The drive mechanism 42 drives the clamping mechanism 44 to move closer to or away from the clamp seat 41 through the swing mechanism 43 to form a limiting space 45. The spring wire 8 passes through the limiting space 45, which can adaptively limit the spring wire 8. This realizes automatic feeding of the spring bed mesh 9, avoids the misalignment of the springs 9 caused by uneven manual force and inconsistent moving speed, and at the same time ensures that the corresponding position of the spring wire 8 and the springs 9 of the spring bed mesh 9 is accurate, reducing the problems of missing or misaligned springs, and improving the quality and efficiency of spring feeding.

[0025] See Figure 3The netting assembly 2 further includes a netting drive gear 23 that is pulsatingly connected to the netting drive component 21, a netting drive rack 24 that meshes with the netting drive gear 23, and a netting connecting rod 25 that is connected to the netting drive rack 24. The netting block 22 is disposed on the netting connecting rod 25, and the netting drive component 21 can drive the netting block 22 to move through the netting connecting rod 25. The netting drive component 21 is preferably a rotary motor. In operation, the power output from the mesh-pulling drive component 21 is first transmitted to the mesh-pulling drive gear 23. Through the mesh-pulling drive gear 23 meshing with the mesh-pulling transmission rack 24, the rotational power of the mesh-pulling drive component 21 is converted into the linear motion of the mesh-pulling transmission rack 24. This, in turn, drives the mesh-pulling connecting rod 25 connected to the mesh-pulling transmission rack 24 to move synchronously in a linear fashion. Ultimately, the mesh-pulling block 22 mounted on the mesh-pulling connecting rod 25 moves together with the mesh-pulling connecting rod 25, thereby pushing the spring bed mesh. Compared to the simple linkage transmission or direct push structure that may exist in the prior art, the mesh-pulling block 22 can significantly improve the stability and accuracy of power transmission through the mesh-pulling transmission, ensuring that the moving speed of the mesh-pulling block 22 is uniform and the displacement is controllable.

[0026] The mesh pulling assembly 2 also includes a mesh pressing plate 26, which is disposed on the side of the workbench 7 near the clamping assembly 4. When the mesh pulling assembly 2 drives the spring 9 bed mesh to move on the workbench 7, the mesh pressing plate 26 presses and limits the bottom of the spring 9 bed mesh upward or the top of the spring 9 bed mesh downward, preventing the spring 9 bed mesh from shifting due to the pushing of the mesh pulling block 22 or its own elasticity. The mesh pressing plate 26 is provided with a clearance hole 261, the length direction of which is the same as the moving direction of the spring 9 bed mesh. The top of the mesh pulling block 22 is provided with a mesh pulling part 221, which can be inserted into the spring 9 bed mesh. The longitudinal section of the mesh pulling part 221 is narrower at the top and wider at the bottom, which facilitates the insertion of the mesh pulling part 221 into the spring 9 bed mesh. The mesh pulling part 221 can pass through the clearance hole 261 and move within the clearance hole 261. The clearance hole 261 provides a channel for the movement of the mesh pulling part 221, ensuring that the mesh pulling part 221 will not be unable to operate normally due to the obstruction of the mesh pressing plate 26 when it moves with the mesh pulling assembly 2.

[0027] See Figure 2The wire pulling assembly 2, the wire feeding assembly 3, and the clamping assembly 4 are all arranged in pairs on the upper and lower sides of the feeding space 11 to simultaneously drive, feed, and limit the spring 9 wire bed in both vertical directions, forming a bidirectional collaborative operation structure. Furthermore, this bidirectional collaborative operation further enhances the driving stability of the spring 9 wire bed and the limiting reliability of the spring wire 8, reducing wire bed offset or spring wire 8 skew caused by uneven force on one side, and further improving the quality and adaptability of the spring wire bed.

[0028] The frame 1 includes a fixed frame 12 and a movable frame 13. The mesh pulling assembly 2, the wire feeding assembly 3, and the clamping assembly 4, located on the upper side of the feeding space 11, are connected to the movable frame 13. The fixed frame 12 provides fixed support for the entire equipment, and the movable frame 13 serves as the mounting carrier for the upper components. A lifting assembly 5 is provided between the movable frame 13 and the fixed frame 12. The lifting assembly 5 includes a rotary drive 51, a rotary rod 52 pulverizedly connected to the rotary drive 51, and a lifting screw 53 pulverizedly connected to the rotary rod 52. The movable frame 13 is connected to the end of the lifting screw 53. The rotary drive 51 can rotate the lifting screw 53 through the rotary rod 52 to drive the movable frame 13 to rise or fall.

[0029] See Figure 3 The rotary drive component 51 can be a manual rotary wheel or a rotary motor. During operation, the rotary drive component 51 outputs power and transmits it to the rotary rod 52, causing the rotary rod 52 to rotate. The rotary rod 52 transmits the rotational power to the lifting screw 53 via a steering gear, causing the lifting screw 53 to move linearly up and down along its own axis. Since the movable frame 13 is connected to the end of the lifting screw 53, the raising and lowering of the lifting screw 53 directly causes the movable frame 13 to rise or fall synchronously, thereby adjusting the distance between the upper mesh assembly 2, the wire inlet assembly 3, and the clamp assembly 4 connected to the movable frame 13 and their corresponding lower components. Therefore, this utility model embodiment can flexibly adjust the spacing between the upper and lower components according to the actual thickness of the spring 9 bed net: when the spring 9 bed net is thick, the lifting component 5 drives the movable frame 13 to rise, increasing the spacing between the upper and lower components to match the bed net thickness; when the spring 9 bed net is thin, the movable frame 13 is driven to fall, reducing the spacing between the upper and lower components, ensuring that the upper and lower pulling net components 2 can synchronously and stably drive the bed net, the upper and lower wire feeding components 3 can synchronously and accurately feed the spring wire 8, and the upper and lower clamping components 4 can synchronously limit the spring wire 8.

[0030] See Figure 4 and Figure 5Before entering the winding seat 32, the wire must first be guided and transitioned by the wire feeder 31. The wire feeder 31 has a wire feed hole 311 and a wire feed cavity 312. The wire feed hole 311 communicates with the wire feed cavity 312, allowing the wire to enter the wire feed cavity 312 from the wire feed hole 311. The wire feed cavity 312 provides temporary accommodation and buffer space for the wire, preventing tangling due to uneven tension in the initial stage of feeding. A wire exit end 313 is located on the side of the wire feeder 31 near the winding seat 32. The wire exit end 313 has a wire exit hole 314, which communicates with the wire feed cavity 312. The wire then extends along the wire feed cavity 312 to the wire exit end 313. Because the wire exit hole 314 communicates with the wire feed cavity 312, the wire can smoothly pass through the wire feeder 31 from the wire exit hole 314 and then be fed to the winding seat 32. The wire feeding hole 311 ensures that the wire can accurately enter the wire feeding seat 31, avoiding initial deviation; the buffering effect of the wire feeding cavity 312 can balance the wire feeding tension and reduce the breakage or deformation of the wire caused by sudden tension changes; the wire exit hole 314 can limit the wire exit direction, ensuring that the wire enters the subsequent winding seat 32 in a stable posture, laying the foundation for the regular preparation of the spring wire 8.

[0031] The winding base 32 has an inlet end 321 near the wire feeder 31. The inlet end 321 has an inlet hole 322. The wire enters the winding base 32 through the inlet hole 322. The wire that passes through the outlet hole 314 of the wire feeder 31 will align with the inlet hole 322 of the winding base 32 and enter the interior of the winding base 32. The winding base 32 is provided with a winding core 323. A spiral shaping groove 324 is provided on the outer side of the winding core 323. The shaping groove 324 communicates with the inlet hole 322, allowing the wire to enter the shaping groove 324 and form a spiral spring wire 8. The wire naturally enters the spiral shaping groove 324 on the outer side of the winding core 323. The spiral structure of the shaping groove 324 guides and shapes the wire, causing it to gradually bend along the trajectory of the shaping groove 324, ultimately forming a spiral spring wire 8 that meets the requirements of a spring. A spring outlet end 325 is provided at one end of the winding base 32 near the clamp assembly 4. A spring outlet hole 326 is provided in the spring outlet end 325, which is connected to the winding core 323. The spring wire 8 can pass through the spring outlet hole 326 and exit the winding base 32, then be transported to the worktable 7 to dock with the spring 9 of the spring bed.

[0032] The wire feeding assembly 3 also includes a wire spool 33 and a wire spool drive 34 that is connected to the wire spool 33. There are two wire spools 33, which are arranged between the wire exit end 313 and the wire feeding end 321. During the process of the wire being fed from the wire exit end 313 of the wire feeder 31 to the wire feeding end 321 of the winding seat 32, it will first pass through the area between the two wire spools 33. That is, after the wire passes through the wire exit end 313, it will naturally embed into the wire pressing grooves 331 on the side of the two wire spools 33. The wire pressing grooves 331 clamp and limit the wire. The yarn-aligning drive 34 drives the yarn-aligning wheel 33 to rotate. The yarn-aligning wheel 33 has a pressure groove 331 on its side, which surrounds the side wall of the yarn-aligning wheel 33. After the yarn passes through the exit end 313, it enters the pressure groove 331 between the two yarn-aligning wheels 33. The yarn-aligning wheel 33 rotates to shape the yarn. The yarn-aligning drive 34 drives and drives the two yarn-aligning wheels 33 to rotate synchronously. During the rotation, the pressure groove 331 applies uniform tension and straightening force to the yarn, smoothing out the bends and wrinkles on the surface of the yarn, so that the yarn is straight before entering the inlet hole 322 of the winding seat 32.

[0033] See Figures 6-8The driving mechanism 42 includes a clamping drive component 421, a cam 422, a clamping drive shaft 423, and a drive bearing 424. The clamping drive component 421 is preferably a rotary motor. The clamping drive component 421 is driveably connected to the clamping drive shaft 423. The drive bearing 424 is located within the clamping seat 41. The clamping drive shaft 423 passes through the drive bearing 424 and is connected to the cam 422. The clamping drive shaft 423 can drive the cam 422 to rotate. As the clamping drive shaft 423 rotates, the cam 422 connected to it rotates synchronously. The swing mechanism 43 includes a swing rod 431. The cam 422 can drive the swing rod 431 to swing. The cam 422, through changes in the radius of its own profile, forms a periodic pushing or releasing force on the swing rod 431, thereby driving the swing rod 431 to swing around its own fulcrum. The clamping mechanism 44 includes a movable seat 441. One end of the swing rod 431 is connected to the movable seat 441. When the cam 422 drives the swing rod 431 to swing, the swing of the swing rod 431 is converted into a linear displacement of the movable seat 441, causing the movable seat 441 to move closer to or further away from the clamp seat 41. The swing rod 431 can drive the movable seat 441 to move relative to the clamp seat 41. The movable seat 441 and the clamp seat 41 enclose the limiting space 45. The swing of the swing rod 431 ultimately changes the size of the limiting space 45 enclosed by the movable seat 441 and the clamp seat 41 to adapt to the limiting requirements of the spring wire 8 under different states. The limiting space 45 formed by the movable seat 441 and the clamp seat 41 can form a ring-shaped limiting for the spring wire 8. Compared with the single-sided limiting of the existing rigid clamp, the limiting stability is stronger, which can effectively prevent the spring wire 8 from shifting laterally during the spring stringing process. This further ensures that the spring wire 8 and the spring 9 of the spring bed are accurately positioned, reduces the problem of missing or incorrect stringing, and improves the accuracy of spring stringing.

[0034] The spring-feeding device further includes a spring-pushing assembly 6, which is disposed on the side of the clamp assembly 4 away from the worktable 7 and located on the upper and lower sides of the feeding space 11, respectively. The spring-pushing assembly 6 includes a slide plate 61, a spring-pushing drive 62, and a spring-pushing plate 63. The spring-pushing drive 62 is preferably a rotary motor. The slide plate 61 is fixed on the clamp seat 41. The slide plate 61 is provided with a guide hole 611, which is arranged along the length direction of the slide plate 61. The spring-pushing plate 63 can be embedded in the guide hole 611 and move within the guide hole 611. The spring-pushing drive 62 is connected to the spring-pushing plate 63, and the spring-pushing drive 62 can drive the spring-pushing plate 63 to move in the direction of the clamp seat 41. When the clamp assembly 4 limits the spring wire 8 and prepares to dock with the spring 9 of the spring bed, the push spring drive 62 outputs power and transmits it to the push spring plate 63. Since the push spring plate 63 is embedded in the guide hole 611 of the slide plate 61 and the guide hole 611 is set along the length direction of the slide plate 61, the guide hole 611 will limit the movement direction of the push spring plate 63, ensuring that the push spring plate 63 can only move along the extension direction of the guide hole 611 (i.e., towards the direction of the clamp seat 41). As the push spring plate 63 moves, it will contact the side of the spring 9 on the spring bed and apply a push force toward the spring wire position, so that the side of the spring 9 is closer to the preset spring wire position.

[0035] The push spring assembly 6 achieves active calibration of the spring 9 position: on the one hand, the guiding effect of the guide hole 611 ensures that the pushing direction of the push spring plate 63 is accurate, avoiding further misalignment of the spring 9 due to the deviation of the push spring direction; on the other hand, the push spring assembly 6 is respectively located on the upper and lower sides of the feeding space 11, and can apply pushing force from both the upper and lower directions of the spring 9 simultaneously, so that the spring 9 is subjected to balanced force, avoiding the spring 9 from tilting or deforming due to unidirectional pushing force; by pushing the side of the spring 9 closer to the spring stringing position, the deviation between the actual position of the spring 9 and the spring stringing wire 8 can be reduced, ensuring that the spring stringing wire 8 can be accurately inserted into the spring 9, further reducing the problems of missing or incorrect spring stringing, and improving the spring stringing accuracy.

[0036] The push spring assembly 6 further includes a push spring drive gear 64 that is connected to the push spring drive member 62, a push spring drive rack 65 that meshes with the push spring drive gear 64, and a push spring connecting rod 66 that is connected to the push spring drive rack 65. The push spring connecting rod 66 is connected to the push spring plate 63. The push spring drive rack 65 located on the upper side of the feeding space 11 is inclined downward, and the push spring drive rack 65 located on the lower side of the feeding space 11 is inclined upward.

[0037] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
