Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, specifically to a horizontal automatic rewinding machine. Background Technology

[0002] For the copper and copper alloy processing industry, slitting and packaging is an essential process. Depending on customer needs, products often need to be packaged into various specifications. Rewinding can achieve the free conversion from large rolls to small rolls. Although existing slitting machines can produce products of various specifications by changing the rear roll, the more product specifications there are, the more rolls are needed. In addition, rolls can cost tens of thousands of yuan, which is a considerable expense for enterprises. Therefore, rewinding machines are needed to solve the above problems.

[0003] Existing unwinding machines cannot effectively position the placed rolls, which can easily cause slippage during unwinding, making them inconvenient to use and difficult to install and disassemble, requiring a lot of time and thus reducing unwinding efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal automatic unwinding machine, which aims to solve the problems of insufficient practicality and inconvenience in installation and disassembly in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal automatic rewinding machine, comprising a frame and two turntables disposed on opposite sides of the top of the frame. Each turntable is equipped with a positioning component, which includes a rotating shaft, three fixed rods, a disc, a first bevel gear, a stepper motor, a drive shaft, and a second bevel gear. The rotating shaft is rotatably mounted at the center of the upper surface of the turntable. The inner side of the turntable has a cavity, and the upper surface has three sliding grooves. A slider is slidably mounted inside each groove. The disc has three circumferentially distributed arc-shaped sliding grooves. The upper end of the rotating shaft is fixedly connected to the center of the lower surface of the disc. The outer surfaces of the three fixed rods slide in cooperation with the inner walls of the arc-shaped sliding grooves, and their bottom ends are fixedly connected to the upper ends of the sliders. The lower end of the rotating shaft penetrates the turntable and extends into the cavity. The first bevel gear is fixedly mounted at the lower end of the rotating shaft. The stepper motor is fixedly mounted on the side wall of the turntable. The drive shaft is rotatably mounted inside the turntable and is connected to the stepper motor. The second bevel gear is fixedly mounted on the drive shaft and meshes with the first bevel gear.

[0006] Furthermore, it also includes a positioning shaft located at the top of the frame, wherein there are three sets of positioning shafts, which are located in the middle of the front side of the frame and are distributed in a triangular pattern.

[0007] Furthermore, a sleeve is fitted onto the positioning shaft located on the right side, and a limiting plate is provided on the sleeve.

[0008] This utility model has the following beneficial effects:

[0009] This utility model provides a horizontal automatic rewinding machine. The material is fixed by a positioning component set on the turntable, and three movable fixing rods form a support frame that can adapt to different core sizes, enhancing the practicality of the equipment, making it convenient for operators to handle, and improving work efficiency. The positioning shaft and limit plate keep the material in a proper tension state to ensure the rewinding effect. At the same time, the fixing rods can be moved by starting the stepper motor, which facilitates the disassembly and installation of the material rolls on the turntable. Attached Figure Description

[0015] like Figures 1 to 4As shown, a horizontal automatic unwinding machine includes a frame 1 and two turntables 2 located on opposite sides of the top of the frame 1. The turntable 2 on the left is a feeding turntable, and the turntable 2 on the right is a receiving turntable. The two turntables 2 are driven to rotate synchronously by a synchronous belt driven by a motor located inside the frame 1. Each turntable 2 is equipped with a positioning assembly, which includes a rotating shaft 3, three fixed rods 4, a disc 5, a first bevel gear 6, a stepper motor 7, a drive shaft 8, and a second bevel gear 9. The rotating shaft 3 is rotatably mounted at the center of the upper surface of the turntable 2. The inner side of the turntable 2 has a cavity, and the upper surface has three sliding grooves. A slider is slidably installed inside the sliding grooves. The disc 5... Three circumferentially distributed arc-shaped grooves are provided. The upper end of the rotating shaft 3 is fixedly connected to the center of the lower surface of the disc 5. The outer surfaces of the three fixed rods 4 slide in contact with the inner walls of the arc-shaped grooves and their bottom ends are fixedly connected to the upper end of the slider. The lower end of the rotating shaft passes through the turntable 2 and extends to the inner side of the cavity. The first bevel gear 6 is fixedly installed at the lower end of the rotating shaft 3. The stepper motor 7 is fixedly installed on the side wall of the turntable 2. The drive shaft 8 is rotatably installed on the inner side of the turntable 2 and is connected to the stepper motor 7 for transmission. The second bevel gear 9 is fixedly installed on the drive shaft 8 and meshes with the first bevel gear 6. When the three fixed rods 4 are closed, they can form a complete cylinder. The outer surface of the cylinder is provided with an anti-slip layer.

[0016] It also includes a positioning shaft 10 located at the top of the frame. There are three sets of positioning shafts 10, which are located in the middle of the front side of the frame 1 and are distributed in a triangular pattern. This facilitates the limiting of materials, flattens the wrinkles on the materials, and plays a role in tensioning the materials. By setting an anti-slip layer on the outer surface of the fixing rod 4, the stability can be further increased, making the device more stable and less prone to slipping during operation.

[0017] A sleeve is fitted on the positioning shaft 10 located on the right side. A limiting plate 11 is provided on the sleeve. The sleeve can rotate on the positioning shaft 10 and be locked by fastening bolts. It is used to limit the edge of the wound material and improve the rewinding quality.

[0018] The frame 1 is equipped with a controller, which is used to control the motor to drive the turntable 2 to rotate and to control the stepper motor 7 to rotate.

[0019] The specific operation process of this utility model is as follows:

[0020] In use, the material to be rewinded is placed on the left turntable 2. The stepper motor 7 is started by the controller, which drives the second bevel gear 9 on the drive shaft 8 to rotate. Then, through the meshing relationship, the disc 5 rotates, which in turn drives the three fixing rods 4 to slide in the arc-shaped groove to fix the material to be rewinded on the left turntable 2. The material is then wrapped around the positioning shaft 10 and placed on the fixing component of another turntable 2, specifically at the three fixing rods 4 on the right turntable 2. Then, the sleeve on the positioning shaft 10 is moved to adjust the height of the limiting plate 11 so that the material reaches a suitable tension to prevent the material from loosening during rewinding and causing a decrease in rewinding quality. When only the core size of the entire roll of material needs to be adjusted, the rewinding operation can be performed on the right turntable 2.
