Description

Technical Field

[0001] This utility model relates to the field of spring production technology, specifically to a winding device for spring production. Background Technology

[0002] In modern buildings, elevators have become an indispensable vertical transportation tool. Their safety and reliability are directly related to the life safety and user experience of passengers. As the core component of the door system, the elevator door return spring is mainly responsible for providing the return power after the elevator door is opened, so that it can close quickly and smoothly, effectively preventing safety accidents such as people or objects being trapped. Winding equipment is required in the spring production process.

[0003] Currently, in existing technologies, during the winding process, one end of the raw material is fixed to one end of a rotating shaft. The rotation of the rotating shaft, in conjunction with the guide roller, guides the raw material and spirals it around the outside of the winding roller. However, in actual use, the spring wire cannot be evenly wound on the winding roller using only the guide roller. Therefore, a winding device for spring production is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a winding device for spring production that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a winding device for spring production, comprising a fixed frame, on which a winding assembly and an auxiliary winding mechanism are mounted, the auxiliary winding mechanism comprising:

[0006] A rotating wheel is rotatably connected to the outer wall of a mounting plate, and a reciprocating lead screw is rotatably connected to the mounting plate;

[0007] A movable seat, which is matched with a reciprocating lead screw, and a fixed ring is fixedly connected to the top of the movable seat;

[0008] An adjustment component is disposed on a movable base.

[0009] Preferably, a guide rod is fixedly connected to the outer wall of the mounting plate, and the guide rod is slidably connected to the movable seat. The rotating wheel and the reciprocating screw are fixed together by a connecting rod. By rotating the reciprocating screw, the movable seat drives the fixed ring to reciprocate. After the spring wire passes through the fixed ring, it is stably limited by the fixed ring. Thus, during the movement of the fixed ring, it can be evenly wound on the winding roller.

[0010] Preferably, the adjustment assembly includes a first swing rod, which is hinged to the top of the movable seat. A second swing rod is rotatably connected to the end of the first swing rod away from the movable seat. A guide wheel is rotatably connected to the second swing rod. The first swing rod and the movable seat are elastically connected by a tension spring. A limit block is fixedly connected to the outer wall of the movable seat. By using the tension spring, the guide wheel applies a certain pressure to the spring wire, straightening the spring wire and improving the subsequent winding effect of the spring wire.

[0011] Preferably, the angle between the first swing rod and the second swing rod is adjusted by a clamping bolt, which allows for adjustment of the clamping force of the subsequent guide wheel on the spring wire.

[0012] Preferably, the inner surface of the fixing ring is inlaid with balls to reduce the friction when the spring wire moves.

[0013] Preferably, the winding assembly includes a mounting frame, on which a winding roller is rotatably connected, and a motor is fixedly mounted on the mounting frame. The output shaft of the motor is fixed to the winding roller, and a drive wheel is fixedly connected to the winding roller.

[0014] Preferably, the drive wheel and the rotating wheel are connected by a synchronous belt drive.

[0015] This utility model provides a winding device for spring production. It has the following beneficial effects:

[0016] (1) The spring production winding equipment drives the fixed ring to move back and forth along the guide rod by the reciprocating screw, so that the spring wire is evenly arranged on the winding roller, avoiding the problem of uneven winding in the traditional winding method. At the same time, the ball embedded in the fixed ring reduces the friction of the spring wire movement, so that it passes smoothly and is stably limited, ensuring that the pitch is consistent and the arrangement is neat during winding.

[0017] (2) The spring production winding equipment forms an elastic pressing structure by combining the swing rod and the tension spring. The guide wheel can apply continuous pressure to the spring wire, automatically straighten the wire and counteract the slack or shaking during the winding process. By adjusting the angle of the swing rod one and the swing rod two, it can flexibly adapt to the tension requirements of spring wires of different diameters, avoid damage to the wire due to excessive tightness or winding deviation due to excessive looseness, and effectively reduce the scrap rate while improving winding efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model proposes a winding device for spring production, including a fixed frame 1, on which a winding assembly 2 and an auxiliary winding mechanism 3 are provided. The winding assembly 2 includes a mounting frame 21, on which a winding roller 22 is rotatably connected. A motor 23 is fixedly mounted on the mounting frame 21, and the output shaft of the motor 23 is fixed to the winding roller 22. The winding roller 22 is fixedly connected to a drive wheel 24. The winding roller 22 is driven to rotate by the motor 23 to achieve winding of elastic wire.

[0028] In this embodiment of the invention, in order to uniformly wind the spring wire, the auxiliary winding mechanism 3 specifically includes a rotating wheel 31 and a movable seat 34. The rotating wheel 31 is rotatably connected to the outer wall of the mounting plate 32. The driving wheel 24 is connected to the rotating wheel 31 via a synchronous belt drive. A reciprocating lead screw 33 is rotatably connected to the mounting plate 32. The movable seat 34 is matched with the reciprocating lead screw 33. A fixing ring 35 is fixedly connected to the top of the movable seat 34. A guide rod 37 is fixedly connected to the outer wall of the mounting plate 32. Furthermore, the guide rod 37 is slidably connected to the movable seat 34, and the rotating wheel 31 is fixed to the reciprocating screw 33 through a connecting rod. The motor 23 drives the winding roller 22 to rotate, which in turn drives the drive wheel 24 to rotate. Under the action of the synchronous belt, the rotating wheel 31 rotates, which in turn drives the reciprocating screw 33 to rotate. Under the action of the guide rod 37, the movable seat 34 can drive the fixed ring 35 to reciprocate on the reciprocating screw 33, so that the spring wire is evenly arranged on the winding roller 22, avoiding the problem of uneven winding in the traditional winding method.

[0029] Furthermore, the inner surface of the retaining ring 35 is inlaid with ball bearings 351. The use of ball bearings 351 can reduce the friction of the spring wire movement, allowing it to pass smoothly and be stably limited, ensuring that the pitch is consistent and the arrangement is neat during winding.

[0030] Furthermore, the auxiliary winding mechanism 3 also includes an adjustment component 36, which includes a swing rod 361. The swing rod 361 is hinged to the top of the movable seat 34. The end of the swing rod 361 away from the movable seat 34 is rotatably connected to a swing rod 362. A guide wheel 363 is rotatably connected to the swing rod 362. The swing rod 361 and the movable seat 34 are elastically connected by a tension spring 364. A limit block 365 is fixedly connected to the outer wall of the movable seat 34. By using the tension spring 364, the swing rod 361 can be pulled, so that the guide wheel 363 applies a certain pressure to the spring wire, making the spring wire taut, counteracting the slack or shaking during the winding process, and improving the subsequent winding effect of the spring wire.

[0031] Furthermore, the angle between the swing rod 361 and the swing rod 362 is adjusted by tightening bolts. By adjusting the angle between the swing rod 361 and the swing rod 362, the tension requirements of spring wires of different diameters can be flexibly adapted, avoiding damage to the wire due to excessive tightness or deflection due to excessive looseness. This improves winding efficiency and effectively reduces scrap rate.

[0032] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0033] In use, the motor 23 drives the winding roller 22 to rotate, which in turn drives the drive wheel 24 to rotate. Under the action of the synchronous belt, the rotating wheel 31 rotates, which in turn drives the reciprocating screw 33 to rotate. Under the action of the guide rod 37, the moving seat 34 can drive the fixed ring 35 to reciprocate on the reciprocating screw 33, so that the spring wire is evenly arranged on the winding roller 22. At the same time, through the use of the tension spring 364, the swing rod 361 can be pulled, so that the guide wheel 363 applies a certain pressure to the spring wire, so that the spring wire is taut when it moves past the guide wheel 363, which helps the winding of the spring wire.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
