Description

Technical Field

[0001] This utility model relates to the field of abrasive belt slitting technology, specifically to a multi-station synchronous cutting device for abrasive belt slitting. Background Technology

[0002] In modern industrial sectors such as machining, furniture manufacturing, and automotive parts production, sanding belts are indispensable grinding and polishing tools with increasingly widespread applications. As market demand for sanding belts continues to grow, the performance and efficiency of sanding belt slitting equipment have become key factors determining the competitiveness of sanding belt manufacturers. Slitting equipment needs to precisely cut entire rolls of raw sanding belts into products of suitable specifications; its operating efficiency and slitting accuracy directly affect the quality of the finished sanding belts and the company's production efficiency.

[0003] However, current belt slitting equipment on the market has significant technical shortcomings. Most traditional equipment adopts a single-station design, requiring a shutdown for loading and unloading after each slitting operation. The equipment is idle during material loading and unloading, and frequent start-ups and shutdowns greatly reduce equipment efficiency, lengthen production cycles, and make it difficult for overall production progress to meet the ever-increasing order demands.

[0004] Furthermore, single-station equipment lacks sufficient flexibility when handling slitting different sizes of abrasive belts. Whenever the abrasive belt size needs to be changed, operators must readjust the equipment parameters and blade positions. This process is not only time-consuming but also demands a high level of skill from the operators; even slight errors can lead to decreased slitting accuracy, affecting product quality and further reducing production efficiency.

[0005] In the material loading and unloading process, the existing equipment generally has a low level of automation and relies heavily on manual operation. Manual operation is not only inefficient and unable to meet the needs of large-scale production, but also poses safety risks. Furthermore, the different working habits of different operators make it difficult to maintain a uniform standard in the material loading and unloading process, resulting in large fluctuations in slitting quality.

[0006] As competition intensifies in the abrasive belt market, the disadvantages of traditional slitting equipment in terms of capacity and efficiency are becoming increasingly apparent, failing to meet the demands of enterprises for efficient and stable production. Developing a new type of abrasive belt slitting equipment with multi-station synchronous operation capabilities, reduced downtime, and improved automation levels for loading and unloading has become a crucial direction for driving technological innovation and industrial upgrading in the abrasive belt production industry.

[0062] Working Principle: At the start of operation, the abrasive belt roll to be slit is fitted onto the feeding roller 14. This equipment features a unique dual-station design, with the left unit 1 and right unit 2 symmetrically distributed on both sides of the device. The central dual-drive cutting blade 3 is positioned between them, forming the first station 4 and the second station 5. These two stations can perform slitting operations simultaneously, greatly improving production efficiency. The central dual-drive cutting blade 3 is one of the core components of the equipment, comprising two sets of cutting blades 6 and two independent cutting blade feed assemblies 7. The cutting blade 6 consists of a blade holder 8, a blade bar 9, and cutting blade wheels 10. The blade bar 9 is fixed to one side of the blade holder 8, and multiple sets of cutting blade wheels 10 are distributed at regular intervals on the blade bar 9. The cutting blade feed assembly 7 is located on the side of the blade holder 8 opposite to the cutting blade wheels 10. The cutting blade feed assembly 7 consists of a first electrically controlled servo telescopic rod 11 and two sets of guide rods 12. The first electrically controlled servo telescopic rod 11 is fixedly installed inside the housing, and its output end is fixedly connected to the tool holder 8. When the equipment is running, the first electrically controlled servo telescopic rod 11 is activated, and its output end drives the tool holder 8 to move, thereby bringing the cutting wheel 10 closer to the abrasive belt roll. At the same time, the guide rod 12 slides in the guide groove 13 to ensure the stability and accuracy of the movement of the tool holder 8 and avoid deviations during the cutting process. During the abrasive belt slitting process, the rotation of the abrasive belt roll is driven by the feeding roller 14. The driving of the feeding roller 14 depends on the planar rotating feeding assembly 15 and the axial rotation assembly 16. The planar rotating feeding assembly 15 includes a rotating block 17, a first servo motor 18, and a rotating shaft 19. The feeding roller 14 is provided with a rotating block 17 at one end near the left unit 1. The rotating block 17 has rotating shafts 19 on both the upper and lower sides, and the rotating shafts 19 correspond to the rotating holes on the housing. The first servo motor 18 is fixedly installed on the top of the housing, and its output end passes through the housing and is coaxially connected to the rotating shaft 19. When loading or unloading is required, the first servo motor 18 starts, driving the rotating shaft 19 to rotate, which in turn causes the rotating block 17 and the loading roller 14 to rotate together in a planar manner. This allows the loading roller 14 to rotate to a convenient position for operation, facilitating the removal of processed materials and the addition of new sanding belt rolls. The axial rotation assembly 16 drives the loading roller 14 to rotate along its axis to cooperate with the cutting wheel 10 in slitting the sanding belt. The axial rotation assembly 16 consists of a moving box 20, a second servo motor 21, a connector 22, and a mating fitting 23. The moving box 20 is located on the side of the rotating block 17 away from the center. The moving box 20 is slidably engaged within the housing, and the second servo motor 21 is fixedly installed inside the box. The output end of the second servo motor 21 extends out of the moving box 20 and is coaxially connected to the connector 22. One end of the mating fitting 23, connected to the central bearing of the rotating block 17, is coaxially connected to the loading roller 14, and the other end is coaxially connected to the connector 22. A second electrically controlled servo telescopic rod 24 is provided on the side of the moving box 20 away from the feeding roller 14. When the equipment is working normally, the second electrically controlled servo telescopic rod 24 drives the moving box 20 to approach the feeding roller 14, so that the joint 22 and the mating part 23 are tightly connected.At this time, the second servo motor 21 starts, driving the feeding roller 14 to rotate axially through the connector 22 and mating part 23, causing the sanding belt roll to rotate as well. During the rotation of the sanding belt roll, the cutting feed assembly 7 drives the cutting blade 6 to feed slowly, and the cutting wheel 10 contacts the rotating sanding belt roll, cutting it and thus slitting the sanding belt material into appropriate sizes. After completing one slitting operation, if loading and unloading operations are required, the second electrically controlled servo telescopic rod 24 drives the moving box 20 to move away from the feeding roller 14, and the connector 22 and mating part 23 are disengaged. Then, the planar rotating feeding assembly 15 drives the feeding roller 14 to rotate horizontally, allowing the operator to easily remove the processed material from the feeding roller 14 and add a new sanding belt roll to be processed. Afterwards, the planar rotating feeding assembly 15 drives the feeding roller 14 to reset, and the second electrically controlled servo telescopic rod 24 drives the moving box 20 to approach the feeding roller 14 again. The connector 22 and the mating part 23 reconnect, and the equipment can start a new round of sanding belt slitting operations. This multi-station synchronous cutting equipment for sanding belt slitting achieves efficient and stable operation of sanding belt slitting through the coordinated work of various components. The dual-station design and automated loading, unloading, and slitting processes significantly improve the production efficiency of the equipment and can meet the needs of large-scale sanding belt slitting processing.
