[0002] A spring mattress is a common household item. The main body of a spring mattress is a spring net. This net typically contains multiple support springs and connecting springs, with the spring forces of the support springs and the connecting springs directed perpendicularly to each other. The support springs provide support, while the connecting springs connect the support springs into a net unit. Multiple net units can be connected to form a complete spring net. When making a spring net, the connecting springs are screwed into the windings of the support springs to connect them. During the process of screwing in the connecting spring, the connecting spring needs to be guided and positioned to prevent the connecting spring from offsetting during rotation. Some existing spring bed nets use a clamping device to guide and position the connecting spring. The existing clamping device usually uses a cylinder or a linear motor to extend and retract from the side of the connecting spring to limit the side of the connecting spring. However, this structure requires occupying the production line length of the spring bed net production equipment, thereby increasing the production line length. In addition, the cylinder or motor needs to precisely control the current or voltage to achieve speed and smoothness adjustment. The control system is relatively complex and requires repeated starting and stopping or forward and reverse rotation, which may have an adverse effect on the life of the motor and has low reliability.

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0024] See also Figure 1 and Figure 2The embodiment of the utility model discloses a clamping device for the production of spring bed nets, including a clamping seat 6, a clamping assembly arranged on the clamping seat 6, a push spring assembly 4 and an ejection assembly 5. The clamping seat 6 is fixed in the spring bed net production equipment, and can fix the reinforcement assembly, the push spring assembly 4 and the ejection assembly 5, and the connecting spring 7 can pass through the clamping assembly. The push spring assembly 4 can push the spring 8 into the clamping assembly, and the elastic force directions of the spring 8 and the connecting spring 7 are perpendicular to each other, wherein the spring 8 is placed vertically, and the connecting spring 7 passes through the spring 8 horizontally to connect multiple springs 8 to form a bed net unit. After that, the ejection assembly 5 can eject the bed net unit from the clamping assembly to facilitate the forward discharge of the spring bed net. Specifically, the clamp assembly includes a driving mechanism 1, a swinging mechanism 2 and a clamping mechanism 3. The driving mechanism 1 includes a cam 11, a driving shaft 12 and a driving bearing 13. The driving bearing 13 is arranged in the clamp seat 6. The driving shaft 12 passes through the driving bearing 13 and is connected to the cam 11. The driving shaft 12 is driven by an external motor. The external motor can drive the driving shaft 12 to rotate, and the driving shaft 12 can drive the cam 11 to rotate. In addition, the swinging mechanism 2 includes a swinging rod 21. The cam 11 can drive the swinging rod 21 to swing. The clamping mechanism 3 includes a fixed seat 31 and a movable seat 32. One end of the swinging rod 21 is connected to the movable seat 32. When the cam 11 drives the swinging rod 21 to swing, the swinging rod 21 can drive the movable seat 32 to move relative to the fixed seat 31, and the connecting spring 7 can pass between the movable seat 32 and the fixed seat 31.

[0025] When in use, the cam 11 drives the swing rod 21 to swing, and the swing rod 21 can drive the movable seat 32 away from the fixed seat 31, forming a limited space between the movable seat 32 and the fixed seat 31, and then the spring 8 is pushed onto the fixed seat 31 by the push spring assembly 4, and the edge of the spring 8 falls between the movable seat 32 and the fixed seat 31, and the swing rod 21 can drive the movable seat 32 to approach the fixed seat 31, and the connecting spring 7 horizontally penetrates between the movable seat 32 and the fixed seat 31. The movable seat 32 and the fixed seat 31 form a limit for the connecting spring 7. By limiting the connecting spring 7 from the left and right sides, a better limiting effect can be obtained, and the connecting spring 7 can be prevented from being offset. Moreover, the rotational motion of the cam 11 can be converted into the linear motion of the movable seat 32. The external motor does not need to be arranged in the length direction of the production line, thereby shortening the length of the production line. Moreover, only the unidirectional rotation of the cam 11 is required to make the movable seat 32 move back and forth periodically, which can avoid repeated starting and stopping or steering of the motor.

[0026] The beneficial effects of the embodiments of the present utility model are as follows:

[0027] The clamping device for producing spring bed nets in the embodiment of the present invention is provided with a clamping seat 6, a clamping assembly arranged on the clamping seat 6, a push spring assembly 4 and an ejection assembly 5, wherein the clamping assembly includes a driving mechanism 1, a swinging mechanism 2 and a clamping mechanism 3, the driving mechanism 1 includes a cam 11, a driving shaft 12 and a driving bearing 13, the driving shaft 12 can drive the cam 11 to rotate, the swinging mechanism 2 includes a swinging rod 21, the cam 11 can drive the swinging rod 21 to swing, when the cam 11 drives the swinging rod 21 to swing, the swinging rod 21 can drive the movable seat 32 to move relative to the fixed seat 31, and before the connecting spring 7 is screwed in, the swinging rod 21 drives the movable seat 32 to move relative to the fixed seat 31. The movable seat 32 is away from the fixed seat 31, so that the connecting spring 7 can enter between the fixed seat 31 and the movable seat 32, and then the connecting spring 7 is screwed in to connect the spring 8. During this process, the movable seat 32 is close to the fixed seat 31 to form two-side limits for the connecting spring 7. Since the drive shaft 12 is used to drive the cam 11 to rotate, the cam 11 drives the swing rod 21 to swing and drive the movable seat 32, the unidirectional rotational motion of the motor can be converted into periodic linear motion of the movable seat 32. The motor does not need to be set in the length direction of the production line, which can shorten the length of the production line and avoid repeated starting and stopping or turning, thereby improving reliability.

[0028] Specifically, see Figure 2 The swing rod 21 includes a hinge part 211, a driving part 212 and a swing part 213. The hinge part 211 is located between the driving part 212 and the swing part 213. The hinge part 211 is hinged to the clamp seat 6. The swing part 213 can swing around the hinge part 211. The driving part 212 is connected to the rolling surface of the cam 11. Therefore, when the flange of the cam 11 rolls to the driving part 212, the driving part 212 can swing, thereby driving the swing part 213 to swing. The swing part 213 is connected to the movable seat 32, so the swing part 213 can drive the movable seat 32 to move.

[0029] See also Figure 4In order to adjust the swing amplitude of the swing portion 213, the driving portion 212 is provided with an adjustment hole 214, which is an oblong hole. The driving portion 212 is also provided with an adjustment rod 22, an adjustment bearing 23 and a locking nut 24. The adjustment rod 22 passes through the adjustment hole 214 and is connected to the adjustment bearing 23. The rotating surface of the adjustment bearing 23 abuts against the rolling surface of the cam 11. The adjustment bearing 23 can rotate, which is different from the cam 11 that directly abuts against the swing portion 213. The contact between the adjusting bearing 23 and the cam 11 can convert sliding friction into rolling friction, reducing friction, and the adjusting hole 214 can adjust the distance between the adjusting bearing 23 and the cam 11. The locking nut 24 can lock the adjusting rod 22 in the adjusting hole 214. When adjustment is required, the locking nut 24 is loosened, the position of the adjusting rod 22 in the adjusting hole 214 is adjusted, and the position of the adjusting bearing 23 is adjusted, and then the locking nut 24 is tightened. By adjusting the distance between the adjusting bearing 23 and the cam 11, the distance that the swinging portion 213 deviates from the cam 11 can be controlled, thereby controlling the swing amplitude of the swinging portion 213. The swing amplitude of the swinging portion 213 can determine the movement distance of the movable seat 32.

[0030] See also Figure 3 The end of the swing portion 213 is provided with a convex rod 25, and the bottom side of the movable seat 32 is provided with a push groove 33, the notch of the push groove 33 is downward, and the convex rod 25 can be inserted into the push groove 33 to connect the swing portion 213 with the movable seat 32. In order to further improve the connection effect and the pushing effect, the convex rod 25 is provided with an inwardly concave arc-shaped sliding groove 251, and the arc-shaped sliding groove 251 can abut against the edge of the push groove 33. When the swing rod 21 drives the During the movement of the movable seat 32, the edge of the push groove 33 can slide in the arc-shaped slide groove 251, and the arc-shaped slide groove 251 can make the movement of the push groove 33 smoother. In addition, the end of the convex rod 25 is provided with an outward-convex arc-shaped protrusion 252, and the side of the arc-shaped protrusion 252 is connected to the arc-shaped slide groove 251. The arc-shaped protrusion 252 can abut against the edge of the push groove 33, and the arc-shaped protrusion 252 protrudes from the surface of the arc-shaped slide groove 251.

[0031] When the swing rod 21 pushes the movable seat 32 to a certain position, the edge of the push groove 33 can slide from the arc-shaped slide groove 251 to the arc-shaped protrusion 252. Since the arc-shaped protrusion 252 protrudes from the surface of the arc-shaped slide groove 251, it can push the movable seat 32 a farther distance than the arc-shaped slide groove 251. Therefore, in the later stage of pushing the movable seat 32 away from the fixed seat 31, the swing rod 21 can push the movable seat 32 faster by relying on the arc-shaped protrusion 252. The seat 32 reaches a farther distance. On the contrary, when the movable seat 32 is driven to approach the fixed seat 31, since the arc-shaped protrusion 252 protrudes from the surface of the arc-shaped slide groove 251, the swing rod 21 only needs to swing in the opposite direction with a small amplitude to make the arc-shaped protrusion 252 abut against the push groove 33. After reaching a certain position, the arc-shaped slide groove 251 abuts against the push groove 33. Therefore, in the early stage of pushing the movable seat 32 to approach the fixed seat 31, a faster response speed and pushing speed can be achieved. The pushing groove 33 has a certain width, so that the swing lever 21 takes a certain amount of time to move from controlling the movable seat 32 to move away from the fixed seat 31 to controlling the movable seat 32 to move closer to the fixed seat 31, that is, the protruding rod 25 swings from one side of the pushing groove 33 to the other side. This time allows the connecting spring 7 to continue to be screwed in between the movable seat 32 and the fixed seat 31, preventing the movable seat 32 and the fixed seat 31 from approaching too quickly and hindering the screwing in of the connecting spring 7.

[0032] In order to ensure that the protruding rod 25 is continuously inserted into the push groove 33 and abuts against the push groove 33, the swing mechanism 2 also includes an elastic member 26, one end of the elastic member 26 is connected to the end of the swing rod 21 away from the swing part 213, and the other end of the elastic member 26 is connected to the clamp seat 6. The elastic member 26 is continuously pulled to generate a reverse pulling force on the driving part 212, thereby ensuring that the flange of the cam 11 can continuously abut against the driving part 212.

[0033] See also Figure 3 The movable seat 32 is provided with a first limiting groove 321 on one side close to the fixed seat 31, and the fixed seat 31 is provided with a second limiting groove 311 on one side close to the movable seat 32. The first limiting groove 321 and the second limiting groove 311 are both notches opened on the side. After the movable seat 32 is away from the fixed seat 31, the connecting spring 7 can pass between the first limiting groove 321 and the second limiting groove 311. Then, the movable seat 32 is close to the fixed seat 31, and the first limiting groove 321 and the second limiting groove 311 can enclose a limiting space 34. The limiting space 34 can limit the connecting spring 7 to prevent the connecting spring 7 from deviating.

[0034] See also Figure 6 The fixing seat 31 is symmetrically provided with stoppers 312 on its upper side. These stoppers 312 form an "eight"-shaped placement space 313, which is communicable with the limiting space 34. The push spring assembly 4 is capable of pushing the spring 8 into the placement space 313. The placement space 313 is in the "eight" shape and can adapt to the edge shape of the spring 8, thereby limiting and positioning the spring 8. With this limitation and positioning achieved, the connecting spring 7 can stably pass through the spring 8.

[0035] In addition, a plurality of limit blocks 314 are provided in the fixed seat 31. The limit blocks 314 are located at the edge of the limit space 34 and protrude toward the movable seat 32. A limit grid 315 is formed between adjacent limit blocks 314. The connecting spring 7 can be inserted into the limit grid 315. After the movable seat 32 approaches the fixed seat 31, the limit grid 315 can form a limit for the spiral line of the connecting spring 7, while allowing the connecting spring 7 to continue to be screwed in, further avoiding the displacement of the connecting spring 7.

[0036] In order to push the spring 8 into the placement space 313, the push spring assembly 4 includes a slide plate 41, a push spring driving member 42 and a push spring plate 43. The slide plate 41 is fixed to the clamp seat 6, and one end of the slide plate 41 is close to the fixed seat 31. A guide hole 411 is provided on the slide plate 41. The guide hole 411 is arranged along the length direction of the slide plate 41. The push spring plate 43 can be embedded in the guide hole 411 and move in the guide hole 411. The push spring driving member 42 is connected to the push spring plate 43. The push spring driving member 42 can drive the push spring plate 43 to move in the direction of the fixed seat 31. Figure 5 One end of the push spring plate 43 is provided with a push spring gap 431, and the push spring gap 431 is a notch on the bottom side of the end of the push spring plate 43, which can lock the spring 8, so that the end of the push spring plate 43 can stably push the spring 8 to move.

[0037] See also Figure 2After the connection is complete, the connected bed net unit needs to be ejected from the clamping device. The ejection assembly 5 includes a limit seat 51, an ejection drive 52, and a push rod 53. The limit seat 51 is fixed to the bottom of the clamping seat 6. The limit seat 51 is provided with an ejection hole 511. One end of the push rod 53 is drivingly connected to the ejection drive 52, and the other end of the push rod 53 can upwardly pass through the ejection hole 511. The ejection hole 511 is located below the limited space 34. When discharge is required, the movable seat 32 moves away from the fixed seat 31, the ejection hole 511 is exposed, and the ejection drive 52 can drive the push rod 53 to rise, thereby lifting the bed net unit located within the limited space 34.

[0038] The present invention also discloses a spring bed net production device, including the clamping device for spring bed net production described above. The cam 11, fixed seat 31, and movable seat 32 of the clamping device for spring bed net production can be used to form two-side limiters for the connecting spring 7. Since the drive shaft 12 is used to drive the cam 11 to rotate, and the cam 11 drives the swing lever 21 to swing, driving the movable seat 32, the unidirectional rotational motion of the motor can be converted into periodic linear motion of the movable seat 32. The motor does not need to be arranged in the longitudinal direction of the production line, which can shorten the production line length and avoid repeated starting, stopping, or turning, thereby improving reliability.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
