Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a single-servo multi-position rolling cutting and punching device. Background Technology
[0002] When packaging multiple bundles together in a pillow-like manner, holes need to be punched in the packaging film to allow excess air to escape during sealing. Currently, the market uses methods such as high-speed cylinder punching and dual-servo punching devices. Cylinder punching has problems such as non-standard punching and tearing, while dual-servo punching devices have disadvantages such as complex structure and difficulty in adjustment. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model discloses a single-servo multi-position rolling cutting and punching device, which solves the technical problems of non-standard punching, tearing, complex structure and difficult adjustment of the existing punching device.
[0004] This utility model is achieved through the following technical solution:
[0005] A single-servo multi-position rolling cutting and punching device includes a frame, on which a servo power input device and a rotatable rolling cutting shaft are mounted. The output shaft of the servo power input device is connected to the rolling cutting shaft via a power transmission mechanism. Several cutting blade modules are mounted on the rolling cutting shaft, and each cutting blade module includes a protruding blade.
[0006] In a further optimized manner, the cutting module includes a fixing member mounted on the cutting shaft and a detachable cutting blade mounted on the fixing member, wherein the cutting blade is provided on the cutting blade.
[0007] In a further optimized configuration, the rotary cutter is mounted on a fixing member, and a clamping member is provided on one side of the rotary cutter. The clamping member, the rotary cutter, and the fixing member are connected as a whole by bolts.
[0008] Further optimized, a locking ring is provided on each of the two roller cutting shafts on both sides of the cutting module to limit the position of the cutting module on the roller cutting shaft.
[0009] In a further optimized manner, a floating roller is provided below each cutting module, and the floating roller is mounted on the frame.
[0010] In a further optimized manner, the power transmission mechanism includes a main pulley mounted on the output shaft of the servo power input device, a driven pulley mounted on the rolling shaft, and a transmission belt connecting the main pulley and the driven pulley.
[0011] In a further optimized manner, the servo power input device includes a servo motor and a servo reducer connected to the servo motor.
[0012] The beneficial effects of this utility model are as follows:
[0013] This utility model features single servo control and synchronous belt drive, which is simple to control, compact and lightweight in structure, smooth transmission, and noiseless. After the servo power input device is started, it transmits power to the roller shaft through the power transmission mechanism. By calculating the distance from the blade to the axis of the roller cutting shaft, the rotation speed of the servo power input device is controlled, so that the cutting module can achieve a completely consistent speed when cutting the packaging film, thereby avoiding uneven rolling holes and tearing.
[0014] Multiple cutting modules can be installed on the roller cutting shaft to achieve the effect of simultaneously cutting round holes at different positions on the packaging film.
[0015] The rotary cutter is fixed separately to the fixing and clamping parts, making it simple and convenient to replace after wear. Attached Figure Description

Detailed Implementation
[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0022] like Figure 1-3 As shown, a single-servo multi-position rolling cutting and punching device includes a frame 1, a servo power input device and a rotatable rolling cutting shaft 2 on the frame 1, the output shaft of the servo power input device is connected to the rolling cutting shaft 2 through a power transmission mechanism, and a plurality of cutting blade modules are provided on the rolling cutting shaft 2, the cutting blade modules including protruding blades 3.
[0023] This invention utilizes a servo power input device. This device transmits power to the roller shaft 2 via a power transmission mechanism. By calculating the distance from the blade 3 to the axis of the roller shaft 2, the rotation speed of the servo power input device is controlled, ensuring that the cutting modules operate at a completely consistent speed when cutting the packaging film. This prevents uneven cutting and tearing. Furthermore, multiple cutting modules can be mounted on the roller shaft 2, allowing for simultaneous cutting of circular holes at different positions on the packaging film.
[0024] In some embodiments, the cutting module includes a fixing member 4 mounted on the rolling cutting shaft 2 and a detachable rolling cutting blade 5 mounted on the fixing member 4, wherein the cutting blade 3 is provided on the rolling cutting blade 5.

The circumferential fixation of the cutter module is achieved by a flat key, and then the axial movement is limited by the locking ring 7.
[0028] In some embodiments, a floating roller 8 is provided below each cutting module, and the floating roller 8 is mounted on the frame 1. To better achieve the rolling cut, the floating roller 8 is arranged below the rolling cutter 5, thereby achieving better adhesion between the rolling cutter 5 and the packaging film.
