Description

A glass fiber comb for a chopped strand machine and the glass fiber chopped strand machine. Technical Field

[0001] This utility model relates to the field of glass fiber manufacturing, specifically to a glass fiber comb for a chopped strand machine and a glass fiber chopped strand machine. Background Technology

[0002] In the production of glass fiber, multiple glass fiber bundles need to be evenly laid on a rubber roller, and then cut with a blade. To ensure the glass fiber bundles are evenly laid on the roller, they must first pass through a "comb," typically made of metal, with multiple evenly arranged teeth. The glass fiber bundles pass through the gaps between the teeth. After a period of operation, the roller and blade will wear down, specifically at the positions corresponding to the glass fiber bundles. This wear prevents the fiber bundles from being cut, necessitating replacement of the roller and blade. However, the replaced roller and blade show little wear at the positions corresponding to the teeth and can still cut the fiber bundles. Discarding these replaced rollers and blades would be wasteful. Summary of the Invention

[0003] This invention provides a glass fiber comb for a chopped strand machine, which can solve the technical problem that only half of the rubber rollers and blades of existing chopped strand machines are worn when they are discarded, resulting in waste. At the same time, it can also improve the efficiency of cutting fiber bundles.

[0004] The glass fiber comb of the short-cutting machine of this utility model has two rows of vertical comb teeth, which are arranged vertically. A comb gap is formed between adjacent comb teeth in each row, and multiple comb teeth in the first row are aligned vertically with multiple comb gaps formed by the second row of comb teeth.

[0005] Preferably, the two rows of vertical comb teeth are located on the same comb body.

[0006] Preferably, the glass fiber comb of the chopped strand machine includes two parallel comb bodies, and each comb body is provided with a row of vertical comb teeth.

[0007] Ideally, the two combs should be aligned vertically.

[0008] Ideally, the two combs should be aligned front to back.

[0009] This utility model also provides a glass fiber chopped strand machine, including a glass fiber comb, a rubber roller, and a cutting roller. The glass fiber comb is as described above. The rubber roller and the cutting roller are both parallel to the glass fiber comb. Glass fiber bundles passing through the glass fiber comb pass between the rubber roller and the cutting roller. The cutting roller is provided with a plurality of blades evenly arranged circumferentially. The blades are parallel to the axial direction of the cutting roller and the cutting edges of the blades face outward. The rubber roller engages with the cutting edges of all the blades of the cutting roller. When the cutting roller rotates, it cuts the glass fiber bundles on the rubber roller and drives the rubber roller to rotate synchronously.

[0010] Compared with the prior art, this invention has the following advantages: Firstly, the glass fiber comb of this invention allows for double the amount of glass fiber bundles laid on the rubber roller, thereby improving the efficiency of chopped fiber bundles. Secondly, the discarded rubber rollers and blades are in a fully worn state, which, compared to the partially worn state of existing discarded rubber rollers and blades, improves utilization and reduces costs.

[0018] This utility model provides a glass fiber comb 1 for a short-cutting machine, as shown in Figure 1. In this embodiment, the glass fiber comb 1 has a comb body 11 with two rows of comb teeth 12 arranged vertically. Adjacent comb teeth 12 in each row form comb slots 13, and the multiple comb teeth 12 of the first row of comb teeth 12 are aligned vertically with the multiple comb slots 13 formed by the second row of comb teeth 12, so that the multiple comb teeth 12 of the first row of comb teeth 12 are staggered vertically with the multiple comb teeth 12 of the second row of comb teeth 12.

[0019] Half of the glass fiber bundle 4 passes through the upper comb slit 13, and the other half passes through the lower comb slit 13. Since the upper and lower comb slits 13 are staggered, there are no gaps formed by the comb teeth 12 between the glass fiber bundles 4 laid on the rubber roller 2. Compared to the existing glass fiber comb 1, the glass fiber comb 1 of this invention allows for double the number of glass fiber bundles 4 laid on the rubber roller 2, thereby improving the efficiency of chopped fiber bundles 4. Simultaneously, the discarded rubber roller 2 and blade 31 are in a fully worn state, compared to the partially worn state of the existing discarded rubber roller 2 and blade 31, improving utilization and reducing costs.

[0020] The comb body 11 is generally made of wear-resistant metal. In this embodiment, the glass fiber comb 1 is made of copper, which can be formed by casting or by other processes.

[0021] In another embodiment (not shown in the figure), two parallel comb bodies 11 can also be provided, each comb body 11 having a row of the aforementioned vertical comb teeth 12. Each comb body 11 can be fixed individually. In this embodiment, the two comb bodies 11 are aligned vertically, and other features are the same as in the above embodiment.

[0022] In another embodiment, two parallel comb bodies 11 are also provided, each comb body 11 having a row of vertical comb teeth 12. Each comb body 11 can be fixed individually. In this embodiment, the two comb bodies 11 are aligned front to back, and other features are the same as in the above embodiment. In other embodiments, the two parallel comb bodies 11 may not be aligned vertically or front to back, as long as the comb seams 13 passing through the two comb bodies 11 are staggered, so that the glass fiber bundles 4 are laid on the rubber roller 2 without gaps.

[0023] This utility model also provides a glass fiber chopped strand machine (not shown in the figure), including a glass fiber comb 1, a rubber roller 2, and a cutter roller 3. The glass fiber comb 1 is the glass fiber comb 1 as described above. The rubber roller 2 and the cutter roller 3 are both parallel to the glass fiber comb 1. The glass fiber bundles 4 passing through the glass fiber comb 1 are laid on the outer wall of the rubber roller 2. The rubber roller 2 and the cutter roller 3 are respectively mounted on the frame (not shown in the figure) by bearings. The cutter roller 3 is provided with a plurality of blades 31 evenly arranged in the circumferential direction. The blades 31 are parallel to the axial direction of the cutter roller 3, and the cutting edge of the blades 31 faces outward. The outer circumferential wall of the rubber roller 2 meshes with the cutting edge of all the blades 31. The cutter roller 3 can rotate under the drive of a driving device. When rotating, it cuts the glass fiber bundles 4 on the rubber roller 2 and drives the rubber roller 2 to rotate synchronously.

[0024] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
