Description

Technical Field

[0001] This utility model mainly relates to the technical field of sheet metal production and processing, specifically to an improved structure for conveyor belt conveying to press black spots on sheet metal. Background Technology

[0002] In the production of particleboard on the Weinconel laminating line, the raw board is wrapped with upper and lower cardboard and then conveyed into the press via a synchronous belt, where it is formed under high temperature and pressure. However, the existing process suffers from a serious black spot contamination problem: powdery particles detached from the cardboard surface (possibly due to wear of the paper base material or adhesive residue) fall into the tooth grooves of the synchronous pulley during conveying, generating intense friction with the high-speed rotating synchronous belt. This friction process generates localized high temperatures (estimated to reach 200-300℃), causing the organic particles to carbonize and turn black. These particles are then carried by the synchronous belt to the belt's working surface, where they penetrate and contaminate the lower cardboard under pressure. After being cured by the high temperature and pressure of the press, the contaminants form irreversible black spot defects on the board surface. Existing technology mainly relies on periodic shutdowns to clean the synchronous pulleys, but this has three major technical drawbacks: 1) The open conveyor structure makes it difficult to control particle dispersion; 2) The synchronous pulley tooth design does not consider chip removal, making it easy for particles to accumulate and form a secondary source of contamination; 3) It leads to an increased product defect rate, and frequent cleaning severely restricts equipment uptime. Utility Model Content

[0003] To address the problems mentioned above in the background art, this utility model provides an improved structure for conveying black spots on pressed plates using a belt conveyor.

[0004] The present invention adopts the following technical solution: a belt conveyor structure for improving the pressing of black spots on sheet metal, comprising a press and a conveying mechanism, wherein the conveying mechanism is disposed at the side end of the inlet of the press;

[0005] The conveying mechanism includes symmetrically arranged drive components and belts, with the belts covering and connected to the drive components at opposite positions, and a plain plate placed on the belts.

[0006] Preferably, the driving component includes a timing pulley and a rotating shaft, with timing pulleys fixed at both ends of the rotating shaft, and a belt connecting the timing pulleys, the belt being wider than the timing pulleys.

[0007] Preferably, the raw board is conveyed to the press via the belt.

[0008] Preferably, the outer side of the synchronous pulley is provided with several drive teeth, and the inner side of the belt is provided with several tooth grooves.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention uses a belt to cover the synchronous pulley, blocking the path of dust and debris into the tooth groove and eliminating frictional carbonization black spot pollution. Specifically, it subverts the traditional transmission system design logic (synchronous pulley width > belt width) and innovatively adopts a narrow pulley and wide belt matching structure (synchronous pulley width 43mm < belt width 60mm). By utilizing the lateral wrapping effect of the belt on the synchronous pulley, a physical isolation barrier is formed, completely blocking the migration path of dust and debris into the tooth groove, thus eliminating the source of frictional carbonization pollution from the root.

[0011] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0020] Please refer to the appendix carefully. Figures 1-4 A belt conveyor structure for improving black spots on pressed boards includes a press 1 and a conveying mechanism 2, wherein the conveying mechanism 2 is disposed at the side end of the inlet of the press 1;

[0021] The conveying mechanism 2 includes a symmetrically arranged drive component and a belt 5. The belt 5 covers and is connected to the drive component at a relative position, and a plain plate 6 is placed on the belt 5.

[0022] In this utility model, the driving component includes a synchronous pulley 3 and a rotating shaft 4. The synchronous pulleys 3 are fixed at both ends of the rotating shaft 4, and a belt 5 is connected between the synchronous pulleys 3. The belt 5 is wider than the synchronous pulleys 3. The raw plate 6 is conveyed to the press 1 through the belt 5. Several driving teeth are provided on the outer side of the synchronous pulley 3, and several tooth grooves are provided on the inner side of the belt 5.

[0023] The working principle of this utility model is as follows: A belt conveyor for improving the structure of pressing black spots on sheet metal.

[0024] By overturning the traditional transmission system design logic (the width of the synchronous pulley 3 is greater than the width of the belt 5), an innovative matching structure of narrow pulley and wide belt 5 is adopted (the width of the synchronous pulley 3 is 43mm < the width of the belt 5 is 60mm). By utilizing the lateral wrapping effect of the belt 5 on the synchronous pulley 3, a physical isolation barrier is formed, which completely blocks the migration path of dust into the tooth groove and eliminates the source of friction carbonization pollution from the root.

[0025] Structural description of this utility model

[0026] Synchronous pulley 3 width reconstruction

[0027] - Original structural defect: The width of the synchronous pulley 3 is 60mm, which is greater than the width of the belt 5 (50mm). The 10mm extension on both sides forms an open area (5mm gap on one side), which causes paper dust to slide into the tooth groove along the edge of the belt 5.

[0028] - New structural design: The width of the timing pulley 3 is reduced to 43mm (8.5mm on each side), ensuring that the width of the belt 5 (60mm) completely covers both sides of the timing pulley 3, forming a coverage margin of 8.5mm on both sides (total coverage margin of 17mm).

[0029] - Geometric constraint principle: Based on particle motion trajectory analysis, when the coverage margin is greater than 340 times the maximum particle size, the possibility of particle intrusion can be completely blocked.

[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
