Description

Technical Field

[0001] This invention belongs to the technical field of wire rod winding equipment, and in particular relates to a wire rod winding machine. Background Technology

[0002] Chinese Patent CN215207565U discloses a stainless steel wire rod winding and collecting device, which includes a winding drum rotatably fixed to a turntable and connected to a first motor on the turntable; a wire feeding support frame located next to the winding drum with several second motors sequentially fixed to its top; the output shaft of each second motor is connected to a rotating shaft; a wire feeding wheel is fixedly mounted on the rotating shaft; a cleaning wheel is located in front of every two wire feeding wheels; the cleaning wheel is fixed to an adjusting slide rod; each adjusting slide rod is slidably fixed to the top of the wire feeding support frame; the first motor is fixed to a base, and several positioning rods are sequentially arranged on the outer circumference of the base; each positioning rod has a positioning wheel, and the positioning wheel is slidably connected to a positioning groove at the bottom of the turntable. The above device has the following drawbacks: because the wire feeding wheel is fixed to the rotating shaft while the winding drum is rotatably fixed to the turntable, the friction between the wire rod and the winding drum is relatively large during the winding process, which may cause wear on the wire rod surface, thus affecting the production quality of the wire rod. Therefore, there is an urgent need to research a wire rod winding machine in order to solve the above problems. Summary of the Invention

[0003] The present invention provides a wire rod winding machine, the purpose of which is to solve the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a wire rod winding machine, comprising a frame and a support platform horizontally fixed to the top of the frame; a vertically arranged drive shaft is rotatably connected to the upper surface of the support platform; the lower end of the drive shaft is connected to the output end of a motor module; the motor module is mounted on the lower surface of the support platform; a bearing plate is coaxially fixed to the upper end of the drive shaft; a winding frame is vertically fixed to the upper surface of the bearing plate; a lifting assembly is vertically mounted on one side of the winding frame; a guide assembly for guiding the wire rod feeding is connected to the lifting assembly. During wire rod feeding, one end of the wire rod passes under the guide assembly and connects to the winding frame. The motor module drives the winding frame to rotate via the drive shaft, while the lifting assembly drives the guide assembly to move up and down, ensuring that the wire rod between the guide assembly and the winding frame is in a horizontal state. This effectively reduces the friction between the wire rod and the winding frame, avoids problems such as wire rod surface wear, and ensures the production quality of the wire rod.

[0006] In a preferred embodiment of the present invention, the lifting assembly includes a mounting base horizontally fixed to the upper surface of a support platform; support columns are vertically fixed at both ends of the mounting base; a first rotating shaft and a second rotating shaft are rotatably connected from bottom to top on opposite sides of the two support columns; a first pulley is fixedly sleeved on the proximal ends of the two first rotating shafts; a second pulley is fixedly sleeved on the proximal ends of the two second rotating shafts; the second pulleys are connected to the first pulley directly above them by a transmission belt; the two transmission belts move in the same direction; the transmission belt is positioned between the two support columns. By rotating the first and second rotating shafts, the first and second pulleys rotate synchronously, thereby causing the transmission belt to move, which in turn drives the guide assembly to move up and down, effectively ensuring the guiding effect of the wire rod.

[0007] In a preferred embodiment of the present invention, the guiding assembly includes a pair of symmetrically arranged first L-shaped blocks; one end of each of the two first L-shaped blocks is connected to the working surfaces of the two transmission belts by a plurality of positioning rivets; a guide wheel is rotatably connected between the other ends of the two first L-shaped blocks; the guide wheel is disposed between the two transmission belts; a pair of parallel movable shafts are rotatably inserted at opposite sides of the other ends of the two first L-shaped blocks; the movable shafts are parallel to the first rotating shaft; a torsion spring is sleeved on one end of the movable shaft; one end of the torsion spring is fixed to the first L-shaped block; the other end of the torsion spring is fixed to the movable shaft; a connecting rod is radially fixed to the other end of the movable shaft; a positioning roller is fixed to one end of the connecting rod; the circumferential sidewall of the positioning roller abuts against the working surface of the transmission belt. By passing the wire rod under the guide wheel and aligning it with the guide surface of the guide wheel, the guide wheel, driven by the transmission belt, can effectively improve the feeding effect of the wire rod while cooperating with the winding frame to wind the wire rod, ensuring smooth feeding of the wire rod. By designing the circumferential sidewall of the positioning roller to abut against the working surface of the transmission belt, and using a connecting rod to connect the movable shaft to the positioning roller, the movable shaft rotates and passes through the first L-shaped block. One end of the movable shaft is fitted with a torsion spring, and the two ends of the torsion spring are respectively connected to the first L-shaped block and the movable shaft, which can ensure the smooth movement of the first L-shaped block under the drive of the transmission belt, further ensuring the guiding effect of the guide wheel on the wire rod.

[0008] In a preferred embodiment of the present invention, the drive shaft and the lifting assembly are connected by a transmission assembly; the transmission assembly is mounted on the upper surface of the support platform; the transmission assembly includes a second L-shaped block vertically fixed to the upper surface of the support platform; a transmission worm is horizontally arranged above the second L-shaped block; one end of the transmission worm is rotatably inserted into the upper end of the second L-shaped block; a first bevel gear is fixedly sleeved on one end of the transmission worm; a second bevel gear meshes with the first bevel gear; the second bevel gear is fixedly sleeved on the outer periphery of the drive shaft; a transmission worm wheel meshes with the transmission worm; the transmission worm wheel is fixedly sleeved on the outer periphery of a third rotating shaft; a pair of side support blocks arranged side by side are rotatably sleeved on the third rotating shaft; both side support blocks are fixed on the second L-shaped block; third pulleys are fixedly sleeved on both ends of the third rotating shaft; the two third pulleys are respectively connected to fourth pulleys via belts; the two fourth pulleys are respectively fixedly sleeved on the opposite far ends of the two first rotating shafts. The drive shaft drives the second bevel gear to rotate, which in turn causes the first bevel gear to drive the two first rotating shafts to rotate synchronously and in the same direction via the transmission worm, transmission worm wheel, third rotating shaft, third pulley and fourth pulley, effectively ensuring the working efficiency of the lifting assembly.

[0009] As a preferred embodiment of the present invention, a feeding assembly is installed above the lifting assembly; the feeding assembly is disposed between two support columns; the feeding assembly includes a pair of side supports respectively horizontally fixed to the upper ends of the two support columns; the horizontal cross-section of both side supports is "[" shaped; a guide shaft perpendicular to the first rotation axis is horizontally fixed between the opposite sides of the two side supports; a slider is slidably sleeved on both guide shafts; a tension spring is provided on one opposite side of each of the two sliders; the tension spring is sleeved on the guide shaft; one end of the tension spring is fixed to the side support; the other end of the tension spring is fixed to the slider; a feeding wheel corresponding to the guide wheel is rotatably connected between the two sliders. During the wire rod feeding process, the wire rod is overlapped on the feeding surface of the feeding wheel from above, and then the wire rod is passed around from below the guide wheel. The feeding wheel and guide wheel are used to feed the wire rod, which can further improve the feeding effect of the wire rod. By connecting the feeding wheel to two sliders, the sliders are slidably sleeved on the guide shaft, and the guide shaft is sleeved with a tension spring. The two ends of the tension spring are respectively connected to the slider and the side support, thereby realizing the elastic installation of the feeding wheel and effectively ensuring the feeding effect of the feeding wheel.

[0010] The present invention has the following beneficial effects:

[0011] During the wire rod feeding process, this invention allows one end of the wire rod to pass under the guide assembly and connect to the winding frame. The winding frame is rotated via a motor module and drive shaft, while the guide assembly moves up and down using a lifting assembly. This keeps the wire rod between the guide assembly and the winding frame in a horizontal position, effectively reducing the friction between the wire rod and the winding frame, avoiding problems such as wear on the wire rod surface, and ensuring the production quality of the wire rod.

[0012] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
