Description

Technical Field

[0001] This utility model relates to the field of roll anti-cut film technology, and in particular to a roll anti-cut film buffer device. Background Technology

[0002] Currently, the film cutting process has a low level of automation and mainly relies on manual operators: workers need to move the sheet material to the cutting table, the cutting table performs the cutting action according to the required pattern, and then the sheet is manually removed. Although this process is simple, it is labor-intensive and labor-intensive, resulting in low production efficiency and a shortage of manpower on the production line. Now, Xinfeng's customer orders are increasing and delivery deadlines are tight, with strict requirements for the surface lamination process. The existing film cutting workshop has low manual cutting efficiency and long delivery times, which cannot meet production needs. In view of the above reasons, the Technical Equipment Department took the lead in proposing a technical transformation of the film cutting process section based on the roll-to-roll production line.

[0003] The online segmented film cutting technology for roll-to-roll stainless steel sheets breaks away from the traditional film cutting method and innovates the existing film cutting process: The traditional film cutting method involves applying film to roll-shaped stainless steel sheets, then proceeding through a leveling process. After the stainless steel roll is cut into sheets of a certain size, it flows through the film cutting process, where a film cutting tool is used to cut the film on a flat plate. The online segmented film cutting technology for roll-to-roll stainless steel sheets eliminates the intermediate transition step. Before applying the film, the film can be directly divided into a certain size and applied to the stainless steel roll. Finally, it flows through the leveling process and is cut into sheets of a certain size.

[0004] However, existing roll-to-roll online segmented film cutting devices still have some problems: before cutting, it is inconvenient to automatically move the cutting blade to the film, and it is also inconvenient to make horizontal cuts to the film, thus reducing the flatness of the cut surface; when the cutting blade cuts the film, the film has radial runout on the "anvil" during unwinding, which can lead to the film not being cut through. To address this, a roll-to-roll film cutting buffer device was designed. Utility Model Content

[0008] Preferably, the inner surface of the slide groove is provided with rolling balls, which are symmetrically arranged on both sides of the slide block, and the surface of the rolling balls is in contact with the surface of the slide block.

[0009] Preferably, a socket is welded to one lower surface of the cylinder mounting seat, and a pin is fixedly provided on one outer surface of the slide, and the pin is fixedly connected to the pin by a third fastening bolt.

[0010] Preferably, the upper surface of the slide is provided with a slot, and the lower surface of the cylinder mounting base is fixedly provided with a locking block for inserting into the slot.

[0011] Preferably, the buffer assembly includes a slide rod, a sleeve, a spring, and a fixed seat. The slide rod is fixedly disposed on the inner side of the blade holder. The sleeve and the spring are both slidably sleeved on the circumference of the slide rod, and one end of the spring is inserted into the inside of the sleeve. One end of the fixed seat is fixedly sleeved on the outer surface of the sleeve, and the cutter seat is fixedly mounted on the other end of the fixed seat.

[0012] Preferably, four sets of the cutting blade and the buffer assembly are respectively provided on the slide rail base.

[0013] Preferably, a servo motor is fixedly installed on one side of the slide rail, and a lead screw is driven to the output end of the servo motor. The lead screw passes through the slide rail and is threadedly connected to the slide rail.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model uses a cylinder to push the blade holder to move, the blade holder to move the cutter seat, and the cutter seat to move the film cutting blade, so that the film cutting blade can automatically move to the film. At the same time, it slides in the slide groove through the slide block, which facilitates horizontal film cutting and helps to increase the flatness of the film cutting surface.

[0016] Secondly, by setting a buffer component on the cutter holder, this utility model can play a buffering role when the film cutting knife is cutting the film, effectively compensating for the radial jump of the film on the "anvil" when the film is unwound, thus effectively solving the problem of the film not being cut through.

The servo motor 22 drives the lead screw 23 to rotate, and the lead screw 23 drives the slide 7 to slide inside the slide groove 6, so that the slide 7 can drive the film cutting knife 15 to reciprocate, thereby completing the film cutting process.

[0032] Operating principle and advantages:

[0033] This invention uses a cylinder 9 to move the blade holder 12, which in turn moves the cutter seat 14, which in turn moves the film cutting blade 15. This allows the film cutting blade 15 to automatically move to the film and slide within the slide groove 6 via the slide block 7, facilitating horizontal film cutting and improving the flatness of the cut surface. A buffer assembly 13 is installed on the blade holder 12, which slides on the slide rod 131 via the sleeve 132. This assembly applies force to the spring 133, causing it to extend and retract. This buffering action effectively compensates for the radial movement of the film on the "anvil" during unwinding, thus effectively solving the problem of the film not being cut through.
