Description

Technical Field

[0001] This utility model relates to the technical field of film slitting equipment, specifically to a chip-proof winding device for a film slitting machine. Background Technology

[0002] During film production, a single sheet of film needs to be cut into strips of specific sizes. To facilitate this process and improve efficiency, film slitting machines are commonly used. However, film slitting generates debris, and the high-speed contact between the film and the cutter causes static electricity to accumulate, attracting and holding the debris.

[0003] Existing anti-debris devices only use fans to remove and collect debris. However, the static electricity generated by the cutting friction attracts debris, resulting in poor removal efficiency from the airflow adsorption method, which cannot completely remove the debris. Therefore, we propose an anti-debris winding device for film slitting machines. Utility Model Content

[0004] The purpose of this utility model is to provide a chip-proof winding device for a film slitting machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A chip-proof winding device for a film slitting machine includes a frame and mounting seats fixedly installed on the frame. Multiple mounting seats are provided. The frame is equipped with a lower cutter shaft and an upper cutter shaft respectively via the mounting seats. A collection mechanism is provided between the frame and the lower cutter shaft and the upper cutter shaft to remove chips generated during cutting. An elimination mechanism is provided inside the frame to eliminate static electricity in the film.

[0007] Preferably, the collection mechanism includes a collection box, which is connected to the upper cutter shaft. The upper cutter shaft has multiple negative pressure holes, and an electrostatic adsorption seat is fixedly installed in each negative pressure hole.

[0008] Preferably, the plurality of electrostatic adsorption seats are electrically connected to each other, and the electrostatic adsorption seats and the frame are electrically connected by contact.

[0009] Preferably, the collection box is equipped with a filter screen and a centrifugal fan, and the collection box is connected to the lower cutter shaft through a pipe. The lower cutter shaft has multiple air blowing holes.

[0010] Preferably, the elimination mechanism includes a mounting roller, which is mounted in the frame via a mounting seat. An adjusting seat is slidably mounted on the mounting roller, and a fixed seat is fixedly mounted on the adjusting seat. A fixed rod is fixedly mounted through the fixed seat.

[0011] Preferably, an elimination rope is wound around the adjusting seat, and the elimination rope is in contact with the fixing rod.

[0012] Preferably, a plurality of lower tool holders are sleeved on the lower tool shaft, and a plurality of upper tools are sleeved on the upper tool shaft.

[0013] By employing the above technical solution, this utility model provides a film slitting machine anti-chip winding device that has at least the following beneficial effects:

[0014] This invention eliminates static electricity generated on the slit film and the upper cutter by setting a collection mechanism on the frame, the upper cutter shaft, and the lower cutter shaft, and setting an elimination mechanism on the frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 A film slitting machine anti-fragmentation winding device includes a frame 1 and mounting bases 2 fixedly mounted on the frame 1. Multiple mounting bases 2 are provided, each consisting of upper and lower parts secured by bolts. The upper part has a removable locking cover, allowing for quick assembly and disassembly. The frame 1 is mounted with a lower cutter shaft 3 and an upper cutter shaft 5 via the mounting bases 2, with the upper cutter shaft 5 positioned above the lower cutter shaft 3. Multiple lower cutter holders 4 are sleeved on the lower cutter shaft 3, and multiple upper cutters 6 are sleeved on the upper cutter shaft 5. Each upper cutter 6 corresponds to one lower cutter holder 4, and the lower cutter holder 4 is fixedly connected to the lower cutter shaft 3 by bolts. The upper cutters 6 are also fixedly connected to the upper cutter shaft 5 by bolts, allowing for position adjustment of both the upper cutters 6 and lower cutter holders 4 to accommodate different slitting widths.

[0027] In this embodiment, a collection mechanism 7 is provided between the frame 1 and the lower cutter shaft 3 and the upper cutter shaft 5 to remove debris generated during cutting. Utilizing a dual adsorption method of electrostatic adsorption and negative pressure adsorption, the debris generated during cutting can be quickly and completely adsorbed and collected, preventing debris from winding with the film and causing problems such as bulging of the film roll. An elimination mechanism 8 is provided inside the frame 1 to eliminate static electricity on the film, preventing the static electricity generated during cutting from adsorbing debris, which would affect the working effect of the collection mechanism 7 and also cause debris to be drawn into the winding process.

[0028] Please see Figures 2-5 A film slitting machine anti-debris winding device includes a collection mechanism 7 comprising a collection box 71. The collection box 71 contains a filter screen and a centrifugal fan. The centrifugal fan generates suction to collect debris into the collection box 71. The filter screen acts as a separator, preventing debris from entering the fan. The collection box 71 is connected to an upper cutter shaft 5. The upper cutter shaft 5 has multiple negative pressure holes 73, allowing the suction generated by the fan to draw suction from inside the upper cutter shaft 5, thereby creating negative pressure in the negative pressure holes 73 and achieving the effect of adsorbing debris.

[0029] In addition, an electrostatic adsorption seat 74 is fixedly installed inside the negative pressure hole 73. Multiple electrostatic adsorption seats 74 are electrically connected to each other, and there is a contact electrical connection between the electrostatic adsorption seat 74 and the frame 1. This allows the electrostatic adsorption seat 74 to be energized after the upper cutter shaft 5 is installed. The cross-section of the electrostatic adsorption seat 74 is triangular. Two electrostatic adsorption seats 74 are installed in one negative pressure hole 73, and the two electrostatic adsorption seats 74 are symmetrically arranged. The space between the negative pressure hole 73 and the electrostatic adsorption seat 74 is larger at the top and smaller at the bottom. This makes the airflow in the negative pressure hole 73 larger as it gets closer to the bottom of the electrostatic adsorption seat 74, which helps to prevent debris from clogging the space.

[0030] It is important to note that the electrostatic adsorption base 74 is insulated from the upper tool shaft 5 to prevent the upper tool shaft 5 from becoming charged and affecting the operation of the electrostatic adsorption base 74. Furthermore, the contact area between the upper tool 6 and the upper tool shaft 5 uses insulating material, ensuring that static electricity generated during the operation of the upper tool 6 will not be transferred to the upper tool shaft 5. The lower tool holder 4 and the lower tool shaft 3 are electrically connected, and a grounding wire is installed at the connection between the lower tool holder 4 and the frame 1, allowing static electricity generated by the upper tool 6 to be discharged through the lower tool holder 4, the lower tool shaft 3, and the grounding wire.

[0031] In this embodiment, the collection box 71 is connected to the lower cutter shaft 3 through a pipe. The lower cutter shaft 3 is provided with multiple air blowing holes 72, so that the airflow generated by the collection box 71 can be blown out along the lower cutter shaft 3 through the pipe and discharged through the air blowing holes 72, which plays a role in blowing and cleaning the upper cutter 6, and can also prevent the debris attracted by the lower cutter shaft 3 when discharging static electricity from adhering to the lower cutter shaft 3.

[0032] Please see Figure 6 The elimination mechanism 8 includes a mounting roller 81, which is mounted inside the frame 1 via a mounting base 2. An adjusting seat 82 is slidably mounted on the mounting roller 81 and is fixed to the mounting roller 81 by bolts, allowing the adjusting seat 82 to slide freely on the mounting roller 81, thereby adjusting its position. A fixing seat 83 is fixedly mounted on the adjusting seat 82, and a fixing rod 84 is fixedly mounted through the fixing seat 83. The fixing rod 84 is composed of two hollow rods sleeved together, with a spring between the two hollow rods. Under the action of the spring force, the fixing rod 84 always has downward pressure, which plays a role in squeezing and fixing.

[0033] In addition, an elimination rope 85 is wound around the adjusting seat 82, and the elimination rope 85 is in contact with the fixing rod 84. The elimination rope 85 is conductive, with one end grounded and the other end in contact with the slit film, thereby removing the static electricity generated in the film during the slitting process and preventing the film from attracting debris due to static electricity.

[0034] A chip-proof winding device for a film slitting machine, the working principle of which is as follows:

[0035] By removing and installing bolts, the position of the adjusting seat 82 can be adjusted so that one end of the eliminating rope 85 makes flexible contact with the slit film, thus removing static electricity. During operation, the centrifugal fan is started, which drives the negative pressure hole 73 to generate negative pressure. Simultaneously, the airflow drawn in is discharged through the blowing hole 72 via a pipe. The electrostatic adsorption seat 74 is energized, generating an electrostatic adsorption effect. Debris generated during film slitting is attracted to the negative pressure hole 73 by the adsorption of the electrostatic adsorption seat 74. Under the suction force of the negative pressure hole 73, it enters the collection box 71 along the inside of the upper cutter shaft 5 and is collected. The airflow from the blowing hole 72 cleans the upper cutter 6 and assists in debris collection, preventing debris from being too far from the upper cutter shaft 5, making adsorption difficult and resulting in incomplete debris collection.

[0036] During operation, the static electricity generated by the cutting of the film and the upper cutter 6 will be discharged through the elimination rope 85 and the lower cutter shaft 3 respectively, to avoid other static electricity affecting the incomplete removal of debris.
