Description

Technical Field

[0001] This utility model relates to the technical field of paper can cutting devices, specifically a support for an adjustable paper can precision cutting machine. Background Technology

[0002] Before the rapid development of the paper can packaging industry, paper can cutting was mostly done manually using simple tools such as utility knives and circular saws. This traditional method had significant drawbacks: not only was the cutting precision low and the work efficiency low, but it also brought considerable safety hazards. Furthermore, manual operation was susceptible to subjective factors such as fatigue and experience level, directly leading to poor product consistency and making it difficult to meet the demands of large-scale production. Therefore, to improve production efficiency, paper can manufacturers need to equip themselves with dedicated paper can cutting machines, whose core function is to cut paper cans to ensure that the length of the paper cans meets production standards.

[0003] In the prior art, utility model patent application number CN201920059865.3 discloses a snack packaging paper can cutting device, including a frame and a base. The base is fixedly installed on the upper left side of the frame, and a push rod seat is fixedly installed on the upper end of the frame. A stepping electric push rod is fixedly installed on the upper end of the push rod seat. Through the design of the horizontal column, the cutter clamp, the stepping electric push rod, and the electric push rod, the paper tube is cut under the push of the electric push rod. The cutting length of the paper can is controlled by the stepping electric push rod. This snack packaging paper can cutting device has a simple structure and is easy to install and maintain. Through the design of the arc block and the filling layer, the arc block is pushed behind the paper tube under the push of the stepping electric push rod. The filling layer is set on the outer surface of the horizontal column, which can support the paper tube when the paper tube is put on the horizontal column, thereby preventing the paper tube from being dented during cutting.

[0004] Although the paper can cutting device disclosed in the aforementioned patent can precisely control the cutting length of the paper can through the stepping motion of a stepper electric push rod, there is still an adaptation problem for different heights of operators in actual cutting operations. The support of the cutting device adopts a fixed structure design, and its height and horizontal position cannot be flexibly adjusted according to actual production needs. This design flaw makes it difficult for the device to adapt to the operating habits of operators of different heights during actual production. Some operators have to work at unsuitable working heights for extended periods, which not only easily leads to fatigue and reduced work efficiency, but may even cause safety accidents due to improper operating posture. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable support for a paper can precision cutting machine, which aims to improve the problem that the support of existing paper can cutting devices is a fixed structure, and its height and horizontal position cannot be adjusted according to actual production needs.

[0015] Preferably, it also includes a reinforcing frame, which is connected to the second electric telescopic rod on the same side.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes multiple second electric telescopic rods within the support device, allowing for flexible adjustment of the overall height of the cutting machine body under the control of a controller. Addressing the varying operating habits of operators of different heights, it eliminates the need for operators to accommodate equipment with a fixed height. By simply setting a suitable height via the controller, operators can perform paper can cutting operations in a comfortable posture.

Combined with the precise control of the upper and lower positions of the cutting tool by the first electric telescopic rod, it can achieve precise cutting of paper cans of different specifications. In addition, the controller can precisely control the cutting position and depth of the cutting tool by coordinating the motor and the first electric telescopic rod, effectively ensuring the consistency and accuracy of paper can cutting and meeting the diverse cutting needs of paper cans of different lengths and specifications in production.

[0018] 3. This utility model effectively improves the overall stability of the support structure by connecting the reinforcing frame between the second electric telescopic rods on the same side in the support device, avoiding the shaking of the support structure caused by vibration during equipment operation. At the same time, the pressure sensor embedded in the support foot pad can monitor the pressure distribution of each support point in real time and feed the data back to the controller. When the pressure difference exceeds the set threshold, the controller can adjust the extension and retraction of the second electric telescopic rod in time to ensure that the equipment is always in a horizontal and stable state.
