Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and more specifically to a glass fiber slitting machine. Background Technology

[0002] Glass fiber reinforced polypropylene (PP) is a modified plastic material that is reinforced by adding glass fibers to a polypropylene matrix. This material combines the excellent processability of polypropylene with the high strength of glass fibers, forming a composite material with superior overall performance.

[0003] During the production process, fiberglass PP needs to be cut into strips of specific widths according to different usage requirements. Traditional slitting machines cut and stretch the fiberglass PP before winding it up from both sides. When the fiberglass PP is pulled and separated, residue will adhere to the support roller. Fiberglass can easily be inhaled into the lungs, causing respiratory diseases and threatening the health and lives of workers. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a glass fiber slitting machine to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a glass fiber slitting machine, including a sorting machine body, in which a rotating slitting roller and a separating roller are arranged. Glass fiber PP is slit from the slitting roller and then wound onto the separating roller. A collection box fixed to its frame is arranged inside the sorting machine body. A knife holder is fixed to the top of the collection box by bolts. One side of the knife holder contacts the separating roller to scrape off the glass fiber PP adhering to the separating roller. An air distribution pipe is welded to one side of the collection box. The other end of the air distribution pipe is fixed to an external pipe that connects to an external vacuum cleaner by a clamp.

[0006] As a further embodiment of this utility model, a groove is provided on one side of the tool holder, and a tool is disposed in the groove.

[0007] As a further embodiment of this invention, the cutting tool is a hardened cutting tool.

[0008] As a further embodiment of this invention, the cutting tool is a soft-tipped tool.

[0009] As a further embodiment of this utility model, partitions are welded to the inner walls on both sides of the collection box, and the partitions and the inner wall at the bottom of the collection box form a guide channel.

[0010] As a further embodiment of this invention, the guide channel has a conical structure that gradually narrows from the outside to the inside.

[0011] As a further embodiment of this invention, there is a gap between the bottom inner wall of the collection box and the separating roller, and the bottom of the collection box extends beyond the knife holder, with a partition located between the bottom of the collection box and the knife holder.

[0012] As a further embodiment of this utility model, the main body of the sorting machine is provided with rotating frames on both sides, and a winding roller is rotatably connected between the inner walls of the two rotating frames. An electric push rod is rotatably connected to the opposite side of the two rotating frames, and the electric push rod is rotatably connected to the frame of the main body of the sorting machine.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model combines the mechanical scraping of the blade holder with the negative pressure adsorption of the vacuum cleaner. This design reduces the amount of glass fiber PP residue on the separating roller from the source, and avoids the problem of fiber scattering caused by the accumulation of residue during equipment operation.

[0014] 2. This utility model, by providing two different types of blades, allows for flexible selection according to actual production needs, improving the equipment's adaptability to different types of residues and ensuring the stable performance of the separating roller during long-term continuous operation.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides a glass fiber slitting machine, including a sorting machine body 1. The sorting machine body 1 is equipped with a rotating slitting roller 4 and a separating roller 9. Glass fiber PP is slit from the slitting roller 4 and then wound onto the separating roller 9. The sorting machine body 1 is equipped with a collection box 6 fixed to its frame. The top of the collection box 6 is fixed with a knife holder 10 by bolts. One side of the knife holder 10 contacts the separating roller 9 to scrape off the glass fiber PP adhering to the separating roller 9. A gas distribution pipe 8 is welded to one side of the collection box 6. The other end of the gas distribution pipe 8 is fixed with an external pipe 7 connected to an external vacuum cleaner by a clamp. When the main body 1 of the sorting machine is running, the slitting roller 4 cuts the glass fiber PP into strips of a set width. These strips are conveyed forward as the separating roller 9 rotates. When the strips pass through the separating roller 9 and separate, the knife holder 10 scrapes off any glass fiber PP that may adhere to the surface of the separating roller 9. The scraped glass fiber PP falls into the collection box 6 below for collection. At the same time, the external vacuum cleaner creates a negative pressure environment in the collection box 6 through the external pipe 7 and the air distribution pipe 8. This not only allows the scraped-off fiberglass PP to be sucked into the collection box 6 in a timely manner, but also prevents the fiberglass PP debris from scattering inside the main body 1 of the sorter, keeping the inside of the equipment clean and ensuring the stable operation of the cutting and separation process. By combining the mechanical scraping of the blade holder 10 with the negative pressure adsorption of the vacuum cleaner, this design reduces the amount of glass fiber PP residue on the separating roller 9 from the source, avoiding the problem of fiber scattering caused by the accumulation of residue during equipment operation.

[0023] In this utility model, a groove 11 is provided on one side of the knife holder 10, and a knife 12 is provided in the groove 11. The knife 12 can be a hard knife or a soft knife, preferably a hard knife. The hard blade is made of high-hardness alloy material, and the blade part is precision ground. It can effectively scrape off the glass fiber PP residue attached to the surface of the separating roller 9, and at the same time has strong wear resistance and can maintain the scraping effect for a long time. The soft blade is made of silicone, which is soft and elastic. When it comes into contact with the separation roller 9, it can closely conform to the surface curvature of the roller and can effectively wipe away some stubborn and fine residues while avoiding hard damage to the surface of the separation roller 9. The cutting tool 12 is fixed to the tool holder 10 by fastening bolts. When the cutting tool 12 is worn or damaged, it can be easily disassembled and replaced, reducing the maintenance cost of the equipment. Two different types can be flexibly selected according to actual production needs: when the glass fiber PP residue adhering to the surface of the separating roller 9 is mainly in large chunks, the hard blade can be used to quickly scrape it off by utilizing its high hardness, ensuring the cleanliness of the surface of the separating roller 9; if the residue is mostly fine fragments with strong adhesion, the elastic adhesion of the soft blade can more thoroughly peel it off from the surface of the separating roller 9, reducing residue; this improves the equipment's adaptability to different types of residue and ensures the stable performance of the separating roller 9 during long-term continuous operation; This flexible selection mechanism allows the invention to be adjusted in a timely manner according to the specific state of the fiberglass PP residue in actual production scenarios, avoiding the problem of residue accumulation caused by poor scraping effect of a single type, thereby effectively improving the smoothness of the entire production process and the stability of product quality. At the same time, by selecting the appropriate blade 12, the service life of the separating roller 9 and the blade 12 can be extended to the maximum extent while ensuring the cleaning effect, thereby reducing downtime and increased production costs caused by frequent replacement of parts. In addition, the gas distribution pipes 8 are arranged in an array on the collection box 6, with their openings facing different areas inside the collection box 6. This can create a uniform negative pressure field inside the collection box 6, avoiding insufficient local negative pressure that could cause fiberglass PP debris to scatter, and further improving the efficiency and safety of residue collection. This multi-dimensional design optimization enables the glass fiber slitting machine to ensure continuous production while minimizing the pollution of the working environment by glass fiber PP residue, effectively protecting the health and lives of workers.

[0024] Furthermore, baffles 13 are welded to the inner walls of both sides of the collection box 6. The baffles 13 and the inner wall of the bottom of the collection box 6 form a guide channel 14. The guide channel 14 has a conical structure and gradually narrows from the outside to the inside. There is a gap between the inner wall of the bottom of the collection box 6 and the separating roller 9. The bottom of the collection box 6 exceeds the knife holder 10, and the baffles 13 are located between the bottom of the collection box 6 and the knife holder 10. When the glass fiber PP residue scraped off by the blade holder 10 falls into the collection box 6, some of the residue will slide down the inclined surface of the partition 13 into the collection box 6. The negative pressure in the collection box 6 will cause the airflow to flow into the collection box 6 from the gap between the collection box 6 and the separating roller 9, and be separated into two airflows by the partition 13. One airflow flows along the upper surface of the partition 13, gathering the sliding residue towards the middle of the collection box 6. The other airflow is accelerated through the conical structure of the guide channel 14, forming a stronger suction at the bottom of the guide channel 14, which quickly draws the collected residue into the suction range of the air distribution pipe 8. This dual airflow guidance design, combined with the conical guide channel 14 to enhance airflow speed, effectively prevents residue from accumulating in the collection box 6, ensuring that the scraped fiberglass PP residue is efficiently sucked into the external vacuum cleaner, further enhancing the equipment's collection effect on fiberglass PP residue and the safety of the working environment.

[0025] Furthermore, both sides of the main body 1 of the sorting machine are provided with rotating frames 3 that rotate on their frames. A winding roller 5 is rotatably connected between the inner walls of the two rotating frames 3. An electric push rod 2 is rotatably connected to the opposite side of the two rotating frames 3, and the electric push rod 2 is rotatably connected to the frame of the main body 1 of the sorting machine. By extending and retracting the electric push rod 2, the rotating frame 3 can be driven to adjust the angle around the frame of the sorting machine body 1, thereby changing the position height and tilt angle of the take-up roller 5. When it is necessary to wind up the slit fiberglass PP strip, the electric push rod 2 extends and pushes the rotating frame 3 to rotate upward, so that the winding roller 5 and the separating roller 9 maintain appropriate tension contact, ensuring that the strip does not become loose or overstretched during the winding process. If it is necessary to pause winding or replace the winding roller 5, the electric push rod 2 extends and pulls the rotating frame 3 to rotate outward. The winding roller 5 then moves away from the separating roller 9, making it easy for operators to quickly remove the wound material roll and install a new winding roller 5. The entire adjustment process does not require manual adjustment, which improves the convenience of equipment operation and production efficiency.

[0026] The working principle of this utility model: When the main body 1 of the sorting machine is running, the slitting roller 4 cuts the glass fiber PP into strips of a set width, and these strips are conveyed forward as the separating roller 9 rotates; When the strip passes through the separating roller 9 and is separated, the cutter 12 on the cutter holder 10 will scrape off the glass fiber PP that may adhere to the surface of the separating roller 9. The scraped glass fiber PP falls into the collection box 6 below for collection. Meanwhile, the external vacuum cleaner creates a negative pressure environment in the collection box 6 through the external pipe 7 and the air distribution pipe 8. The negative pressure causes the airflow to flow into the collection box 6 from the gap between the collection box 6 and the separating roller 9, and is divided into two airflows by the partition 13. One airflow flows along the upper surface of the partition 13, gathering the sliding residue towards the middle of the collection box 6. The other airflow is accelerated by the conical structure of the guide channel 14, forming a stronger suction at the bottom of the guide channel 14, which quickly sucks the collected residue into the suction range of the air distribution pipe 8. By combining the mechanical scraping of the blade holder 10 with the negative pressure adsorption of the vacuum cleaner, this design reduces the amount of glass fiber PP residue on the separating roller 9 from the source, avoiding the problem of fiber scattering caused by the accumulation of residue during equipment operation.
