Description

Technical Field

[0001] This utility model relates to the field of felt slitting technology, and specifically to a felt slitting device. Background Technology

[0002] Felt, as an important material widely used in various fields such as industry, home decoration, and artistic creation, plays a crucial role in its processing. The slitting process plays a vital role in the slitting of felt. After slitting, the felt needs to be quickly and accurately rolled into multiple independent rolls for subsequent storage, transportation, and use. However, the existing felt slitting equipment has an unreasonable design of the winding rollers, which fails to effectively cope with the diversity of felt widths after slitting. Due to the lack of an effective limiting mechanism on both sides of felt of different widths, the rolled felt often suffers from problems such as looseness and deformation, which seriously affects the final quality of the product. Therefore, we propose a felt slitting device. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1-5 A felt slitting device includes a frame 1, on which a plurality of conveying rollers 2 for conveying felt are provided. The plurality of conveying rollers 2 work together to form a continuous path for conveying felt.

[0025] The frame 1 is equipped with several winding units for winding up the slit felt. Each winding unit includes a winding roller 41. A roll 42 is fitted on the outer wall of the winding roller 41. The roll 42 can be pulled out through one end of the winding roller 41 for easy disassembly and replacement. A pair of limiting discs 44 are fitted on the outer wall of the roll 42 to limit the felt wound to the outer wall of the roll 42, so that the felt is neatly slit and wound. A limiting block 45 is provided on the opposite side of the two limiting discs 44. A second bolt 46 is threaded into the limiting block 45 to abut against the outer wall of the winding roller 41 and fix the position of the limiting disc 44. The two ends of the outer wall of the roll 42 are symmetrically provided with strip grooves 43 that penetrate its inner cavity for the second bolt 46 to pass through. The second bolt 46 passes through different positions of the strip groove 43, so that the distance between the two limiting discs 44 changes. This can flexibly adapt to felt of different widths after slit, ensuring that they can be neatly and stably wound up.

[0026] Before use, adjust the position of the drum 42 on the take-up roller 41 to a suitable position, then adjust the distance between the limiting discs 44 on both sides to accommodate the width of the divided felt, then tighten the second bolt 46 to fix the limiting discs 44 and the drum 42, and then drive the drum 42 to rotate by rotating the take-up roller 41 to neatly wind up the divided felt.

[0027] In this embodiment, the frame 1 is provided with a slitting unit for cutting felt. The slitting unit includes a slitting shaft 31, and a plurality of cutting discs 32 are sleeved on the slitting shaft 31 to facilitate the cutting of felt into multiple parts at one time. The cutting discs 32 are symmetrically provided with collars 33 on both sides, and the collars 33 are internally threaded with first bolts 34. By tightening or loosening the first bolts 34, the cutting discs 32 on the slitting shaft 31 can be positioned in different positions. This not only makes it easy to divide the felt into multiple parts at one time, but also allows for precise adjustment of the spacing between each cutting disc 32, thereby meeting the slitting requirements of different widths of felt and improving the diversity and flexibility of slitting.

[0028] In this embodiment, a positioning groove 35 is provided on the cutting shaft 31 along its axial direction, penetrating both ends, so that the screw part of the first bolt 34 can be inserted. The screw part of the first bolt 34 is screwed into the positioning groove 35, making the fixing of the cutting disc 32 more stable.

[0029] In this embodiment, a support roller 6 for supporting the felt is provided below the slitting unit. Several annular grooves 61 are spaced apart on the surface of the support roller 6. During cutting, the grooves 61 are set to correspond to the cutting disk 32 to avoid contact between the cutting disk 32 and the surface of the support roller 6, thereby reducing the wear of the cutting disk 32.

[0030] In this embodiment, the frame 1 is symmetrically provided with waist-shaped grooves 7 for the two ends of the support roller 6 to be inserted. Both sides of the support roller 6 are provided with a pair of pads 62. The opposite side of the paired pads 62 is provided with a nut 63. The two ends of the support roller 6 are screw parts and are threadedly connected to the nuts 63. By rotating the nuts 63 on both sides, the clamping of the pads 62 on both sides against the side wall of the frame 1 can be loosened. Then the support roller 6 can be adjusted so that its two ends move in the waist-shaped grooves 7. When the distance between the top of the support roller 6 and the cutting disc 32 reaches a suitable distance, the nuts 63 can be tightened to facilitate the cutting of felt of different thicknesses.

[0031] In this embodiment, a motor 51 is provided on the frame 1, and a drive disk 52 is provided at the output end of the motor 51. A belt 53 is driven to the outer wall of the drive disk 52, and a number of driven disks 54 are driven to the inside of the belt 53. The driven disks 54 are connected to the end of the take-up roller 41. The motor 51 serves as a drive source and can drive the drive disk 52 to rotate. Furthermore, the belt 53 drives the number of driven disks 54 to rotate synchronously, thereby realizing that the number of take-up rollers 41 can synchronously take up the slit felt.
