Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slitting machine devices, specifically a pressure roller device for a slitting machine that is easy to install and disassemble. Background Technology
[0002] A slitting machine is a mechanical device that cuts wide sheets of paper or film into multiple narrow strips of material. After slitting, the material needs to be wound up. In order to avoid problems such as large swinging of the winding stripes, slippage causing wrinkles, horizontal lines, and wavy stripes on the surface during the winding process, pressure roller devices are needed to improve the winding quality.
[0003] The existing patent CN221587422U discloses a pressing device for a slitting machine take-up roller, comprising: a frame; a take-up roller, which is horizontally arranged and rotates around its own axis on the frame; a pressure roller, which is arranged directly above the take-up roller and whose axial direction is parallel to the take-up roller's axial direction; and a movable component, which is a sliding or rolling component arranged between the two ends of the pressure roller shaft and the frame. The movable component's movement path includes a pressing path, which extends vertically. The pressure roller, connected to the movable component on the pressing path, is used to press the film material onto the take-up roller. This pressing device for a slitting machine take-up roller places the pressure roller directly above the take-up roller, relying solely on the weight of the pressure roller itself to apply pressure to the film material on the take-up roller. This ensures the take-up quality while reducing the weight of the pressure roller, thereby facilitating the adjustment of the pressure roller's position and making manual operation more convenient and labor-saving.
[0004] However, due to the fact that the existing technology, patent number CN221587422U, is installed between two guide rails, the pressure roller becomes thinner due to long-term friction with the material and is inconvenient to disassemble and assemble when it needs to be replaced. Utility Model Content
[0005] The purpose of this utility model is to provide a pressure roller device for a slitting machine that is easy to install and disassemble, so as to solve the problem mentioned in the background art that the pressure roller is installed between two guide rails, which makes it difficult to disassemble and install when the pressure roller becomes thin due to long-term friction with the material and needs to be replaced.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure roller device for a slitting machine that is easy to install and disassemble, including a mounting frame, a lifting frame inside the mounting frame, an upper pressure roller inside the lifting frame, an installation cavity at one end of the upper pressure roller, a telescopic spring inside the installation cavity, and a telescopic rod at one end of the telescopic spring.
[0007] Preferably, a limiting rod is provided at the end of the upper pressure roller away from the telescopic rod, and limiting holes are provided at both ends of the lifting frame. The limiting holes facilitate the insertion of the limiting rod and the telescopic rod, thereby installing the upper pressure roller inside the lifting frame.
[0008] Preferably, the upper end of the mounting frame is provided with an electric push rod, and the lifting frame is driven to rise and fall by the electric push rod. The electric push rod can drive the lifting frame to rise and fall, which makes it easy to adjust the distance between the upper pressure roller and the winding roller according to the thickness of the material.
[0009] Preferably, one end of the mounting bracket is provided with a drive motor, and the drive end of the drive motor is provided with a rotating shaft, which can be driven to rotate by the drive motor.
[0010] Preferably, a take-up roller is provided at one end of the rotating shaft. The take-up roller is located below the upper pressure roller and is parallel to it. The rotation of the rotating shaft facilitates the driving of the take-up roller to take up the material.
[0011] Preferably, a displacement sensor is provided at the lower end of the lifting frame, and a control switch is provided at the outer end of the mounting frame. The control switch is electrically connected to the displacement sensor. The displacement sensor facilitates the detection of the distance between the upper pressure roller and the winding roller, and allows the operator to control the distance of the upper pressure roller according to the thickness of the material using the control switch.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This easy-to-install and disassemble slitting machine pressure roller device, through the setting between the telescopic spring and telescopic rod at one end of the upper pressure roller, when installing the upper pressure roller, first insert the limiting rod at one end into the limiting hole on the lifting frame, then press the telescopic rod at the other end to cause the telescopic spring to drive the telescopic rod to retract, thereby installing the upper pressure roller parallel in the lifting frame. Then release the press, at this time the telescopic spring returns to its original position and pushes the telescopic rod into the other limiting hole to complete the installation. This makes the upper pressure roller easy to install and disassemble, improves the replacement efficiency, and enhances the practicality of the easy-to-install and disassemble slitting machine pressure roller device.
[0014] 2. This easy-to-install and disassemble slitting machine pressure roller device, with the addition of a displacement sensor, facilitates the detection of the distance between the upper pressure roller and the take-up roller. This allows operators to control the electric push rod to raise and lower the lifting frame according to the material thickness via a control switch, and to adjust the distance between the upper pressure roller and the take-up roller according to the material thickness, thus facilitating better material clamping and improving the adjustment effect of the easy-to-install and disassemble slitting machine pressure roller device.
