Description

Technical Field

[0001] This utility model relates to the field of sponge processing equipment, specifically to a sponge mesh belt suction flat cutting machine. Background Technology

[0002] Sponge material, widely used in furniture, mattresses, automotive interiors, packaging, and medical applications, directly impacts product quality and production costs through its processing precision and efficiency. Sponge cutting requires a balance between flexibility and stability. Traditional mesh belt suction flatbed cutters also face these challenges, particularly when processing large areas of sponge sheets: due to the elastic properties of sponge, the cut surface is prone to unevenness and thickness variations, especially noticeable when processing large sheets; sponge is lightweight and highly elastic, making it susceptible to displacement or deformation during cutting, leading to decreased cutting precision. Mesh belt suction flatbed cutters themselves suffer from the following issues: support rollers are typically only installed at both ends of the conveyor belt, lacking effective support in the middle area, causing the conveyor belt to easily sink in the cutting area, affecting the flatness of the cut. This can be due to various reasons, including tension adjustment issues or unevenness of the conveyor belt itself. Furthermore, the suction design results in insufficient physical support at the bottom.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0017] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0018] Example 1

[0019] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a structural diagram of the supporting structure.

[0020] like Figure 1As shown, a sponge mesh belt suction flat cutting machine includes: a cutting blade holder 100, a conveying system 200, a suction device 300, an automatic tension adjustment device 400, and a support structure 500. The cutting blade holder 100 is located above the conveying system 200, the suction device 300 is located below the conveying system 200, the automatic tension adjustment device 400 is connected to the conveying system 200, and the support structure 500 is connected to the conveying system 200.

[0021] The tension automatic adjustment device 400 includes a tensioning wheel 410, a pressure application unit 420, a guide rail 430, and a force sensor 440. The tensioning wheel 410 is mounted on the guide rail 430, the pressure application unit 420 is connected to the tensioning wheel 410, the force sensor 440 is located between the tensioning wheel 410 and the pressure application unit 420, and the tensioning wheel 410 is connected to the conveying system 200.

[0022] The conveying system 200 includes: a support frame 210, a conveyor belt 220, a suction hole 230, and a transmission motor 240. The conveyor belt 220 is mounted on the support frame 210 and connected to the transmission motor 240. The transmission motor 240 is connected to the support frame 210. The suction hole 230 is mounted on the conveyor belt 220 and a ventilation device 300 is provided below the suction hole 230. The conveyor belt 220 is connected to a tensioning wheel 410.

[0023] like Figure 2 As shown, the support structure 500 includes: a support roller array 510, a roller support frame 520, a bearing 530, and a mounting and fixing mechanism 540. The support roller array 510 is connected to the conveyor belt 220. The support roller array 510 and the suction holes 230 are arranged alternately. The support roller array 510 is provided with the bearing 530. The roller support frame 520 is provided with the bearing seat 521. The bearing seat 521 is connected to the bearing 530. The roller support frame 520 is connected to the support frame 210 through the mounting and fixing mechanism 540. The support roller array 510 is made of chrome-plated material.

[0024] The innovation of this invention lies in the following: Through a multi-level support structure 500, uniform and dense support points are provided below the conveyor belt, supporting the roller array 510. This ensures the flatness of the conveyor belt in the cutting area, significantly improving the flatness and thickness consistency of the cut surface. The support roller array 510 adopts a multi-row small-diameter roller design, staggered with the suction holes 230, providing sufficient support without affecting the suction effect, thus solving the problem of mutual interference between support and suction in traditional equipment. The support roller array 510 is made of chrome-plated material, ensuring smooth direct rotation. The principle is that the support structure 500 directly acts on the upper conveyor belt 220, providing sufficient support for the upper conveyor belt in contact with the sponge while avoiding affecting suction. The staggered arrangement with the suction holes resolves the contradiction between support and suction functions, ensuring sufficient support area without hindering the suction effect, achieving optimized coexistence of the two functions. Flexible materials such as sponges require stable reaction forces when cutting. Multi-point support can provide a more stable reaction force field and reduce material deformation during the cutting process.

[0025] On the other hand, the automatic tension adjustment device 400 monitors the belt tension in real time through the force sensor 440. The force sensor continuously monitors tension changes and feeds the signal back to the control system. The pressure application unit adjusts the position of the tensioning wheel based on the feedback, forming an automatic adjustment closed loop. During long-term use, the conveyor belt 220 will experience elastic fatigue and plastic deformation. The automatic tension system can compensate for these changes, extending the service life of the conveyor belt 220. Moreover, during the cutting process, the stress on the belt will change dynamically. The automatic adjustment system can respond to these changes in real time, maintaining the system in optimal working condition. Adjusting the position of the tensioning wheel 410 maintains constant tension, extending the service life of the conveyor belt and improving cutting stability. Its principle is to directly act on the lower conveyor belt 220, providing a tensioning wheel 410 to adjust the tension of the lower conveyor belt 220. The specific method of use is as follows: the tensioning roller 410 is connected to the conveyor belt 220. The tensioning roller 410 receives downward pressure through the pressure application unit 420, which is used to change the height of the tensioning roller 410. In this embodiment, the pressure application unit 420 is an electric push rod. The tensioning roller 410 slides on a guide rail 430 on one side, which can be regarded as its moving platform. During this process, the force relationship between the tensioning roller 410 and the pressure application unit 420 can be fed back by the force sensor 440, which can quantitatively reflect the state of the conveyor belt 220 for more scientific adjustment.

[0026] Although the cutting blade holder 100 and the exhaust device 300 have complex structures, they are both existing equipment. The sponge mesh belt suction flat cutting machine is a mature piece of equipment, and the cutting blade holder 100 and the exhaust device 300 are essential structures for it. Therefore, this utility model does not need to disclose its technical details or protect its technical features.

[0027] Compared with traditional technologies, this invention solves the problems of unstable belt tension and insufficient support during use by adding an automatic tension adjustment device and a support structure.

[0028] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
