Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and more specifically, to a wire feeding device for processing mattress springs. Background Technology

[0002] Spring mattresses are a commonly used and high-performance type of mattress, with their core composed of springs. These mattresses offer advantages such as good elasticity, excellent support, high breathability, and durability, and can flexibly expand and contract according to the curves and weight of the human body. Spring mattresses can evenly support every part of the body, keeping the spine naturally straight, thus allowing muscles to fully relax. Therefore, springs are a crucial component of spring mattresses, and the spring manufacturing process requires the use of a coiling device to lay the coils.

[0003] A search revealed that patent application CN202020760908.3 discloses a wire feeding device for mattress spring processing. This device includes a base and a motor. A processor and a controller are installed inside the base. A second bearing and a rocker arm are installed inside the wire feeding box. A gear is mounted on one side of the rocker arm, and a rotating ring is mounted on the side of the gear away from the rocker arm. A screw is sleeved inside the rotating ring. A seat is installed inside the wire feeding box. A locking block is installed inside the slide groove. A ring is mounted on one side of the locking block, and a movable ring is movably mounted inside the ring. A spring is mounted at the bottom of the ring, and a pressure block is mounted at the bottom of the spring. A sensor is installed inside the support. This wire feeding device for mattress spring processing has advantages such as uniform wire feeding and preventing wire deviation, solving the problems of uneven wire feeding speed and deviation. However, it still has the following drawbacks:

[0004] (1) The wire feeding equipment in the prior art can only unwind and feed wire coils with the same inner diameter. Since the inner diameter of wire coils from different manufacturers is different, it is inconvenient to feed wire coils with different inner diameters, and the flexibility is poor.

[0005] (2) The wire feeding equipment in the prior art adjusts the tension of the steel wire by extrusion, but the tension adjustment effect is not good, which affects the smoothness of wire feeding.

[0006] Therefore, we have made improvements to this and proposed a wire feeding device for mattress spring processing. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a wire feeding device for processing mattress springs, including a base plate 1. A mounting plate 2 is fixedly connected to the left end of the upper surface of the base plate 1. A rotating ring 3 is rotatably connected inside the mounting plate 2. A circular plate 4 is fixedly connected to the front end of the rotating ring 3. Three movable openings are evenly opened on the circular plate 4, and each of the three movable openings is provided with a slide head 5. One end of the slide head 5 is fixedly connected to an inner support column 6, and the other end of the slide head 5 is rotatably connected to a connecting rod 7.

A bracket 10 is fixedly connected to the mounting plate 2, and a telescopic cylinder 11 is fixedly connected to the bracket 10. The driving end of the telescopic cylinder 11 is fixedly connected to the inner wall of the inner ring of the bearing 9. A rotating structure 12 for driving the circular plate 4 to rotate is provided on the mounting plate 2. A guide structure 13 and a tensioning structure 14 are arranged sequentially on the right side of the mounting plate 2. A mounting frame 15 is fixedly connected to the right end of the upper surface of the base plate 1. A pressure plate is fixedly connected to the inner top wall of the mounting frame 15. The force sensor 16 has two through holes symmetrically opened on the upper end of the mounting frame 15, and vertical rods 17 are slidably connected in both through holes. The bottom end of the vertical rods 17 is fixedly connected to the assembly frame 18. Springs 19 are sleeved on the vertical rods 17. The upper and lower ends of the springs 19 are fixedly connected to the mounting frame 15 and the assembly frame 18, respectively. A contact block 20 is fixedly connected to the upper end of the assembly frame 18, and a guide wheel 21 is rotatably connected inside the assembly frame 18. The telescopic cylinder 11 can drive the movable head 8 to move.

This facilitates the fixing of steel wire coils with different inner diameters and the unwinding of steel wire coils with different inner diameters. When the production processing area applies tension to the steel wire, the guide wheel 21 is forced to move the assembly frame 18 and the contact block 20 upward. After the pressure sensor 16 detects the pressure, it transmits the information to the controller 22, and the controller 22 controls the unwinding of the wire.

[0032] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the guide structure 13 further includes a mounting tube 1301 fixed on the base plate 1. The mounting tube 1301 is connected to a post 1303 by a bolt assembly 1302. A guide ring 1304 is fixedly connected to the top of the post 1303. A steel wire passes through the guide ring 1304 for easy guidance. The post 1303 and the mounting tube 1301 are assembled by the bolt assembly 1302, which facilitates disassembly and replacement of the worn guide ring 1304.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the tensioning structure 14 further includes a connecting plate 1401 fixed on the base plate 1. Fixed wheels 1402 are installed at both ends of the connecting plate 1401. Two connecting pieces 1403 are fixedly connected to the rear side wall of the connecting plate 1401. A threaded rod 1404 is rotatably connected between the two connecting pieces 1403. A servo motor 1405 is fixedly connected to the upper connecting piece 1403. The drive end of the servo motor 1405 is fixed to the top end of the threaded rod 1404. The threaded rod 1404 is threadedly connected to a movable block 1406.

[0034] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, a controller 22 is further installed on the upper surface of the base plate 1, the pressure sensor 16 is electrically connected to the controller 22, and the controller 22 is electrically connected to the rotary motor 1203; this facilitates intelligent control.

[0035] like Figure 1 As shown, in a preferred embodiment, based on the above method, a frame 23 is fixedly connected to the lower end face of the base plate 1, and support feet 24 are fixedly connected to the four corners of the lower end face of the frame 23; this facilitates support for the base plate 1 and ensures stability during operation.

[0036] Specifically, in use, the wire feeding device for mattress spring processing works as follows: the wire tube is sleeved on the inner support column 6, the telescopic cylinder 11 drives the movable head 8 to move inward, the movement of the movable head 8 drives the connecting rod 7 to move, thereby causing the slide head 5 and the inner support column 6 to move outward, thus supporting and fixing the wire coil from the inside. The wire is then passed sequentially through the guide ring 1304, the fixed wheel 1402, the movable wheel 1408, the fixed wheel 1402, and the guide wheel 21. The servo motor 1405 drives the threaded rod 1404 to rotate, thereby driving the moving block 14 06. The mounting column 1407 and the moving wheel 1408 move downward to adjust the tension of the steel wire. When the production and processing area applies tension to the steel wire, the guide wheel 21 is forced to move the assembly frame 18 and the contact block 20 upward. After the pressure sensor 16 detects the pressure, it transmits the information to the controller 22. The controller 22 controls the rotary motor 1203 to work. The rotary motor 1203 drives the gear 1204 to rotate. The rotation of the gear 1204 drives the gear ring 1201, the rotating ring 3 and the circular plate 4 to rotate, thereby performing the wire feeding operation.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
