Description

Technical Field

[0001] This utility model relates to the field of fiber processing technology, and in particular to an automatic and efficient short fiber forming equipment. Background Technology

[0002] Short fibers have wide applications in many industrial fields such as textiles, papermaking, and composite materials. In the early days, they were mainly cut manually with simple blades or semi-automated by mechanical transmission combined with manual operation of the blades. This method has a relatively simple equipment structure, but it suffers from problems such as low cutting accuracy, low efficiency, and high labor intensity, making it difficult to meet the needs of large-scale industrial production.

[0003] Chinese Patent 201720310955.6 discloses a cutting device for cutting long filament bundles into short fibers. The cutting device includes a cutter disc and a pressure roller. The cutter disc includes a rotatable disk and several cutting components distributed on the circumferential surface of the disk. Each cutting component extends along the axial direction of the disk and includes a base portion and a cutting edge portion disposed on the base portion. The base portion is fixedly connected to the disk, and the cutting edge portion faces away from the center of the disk. The projection of the cutting edge portion along the axial direction of the disk is triangular. The pressure roller presses the filament bundle against the cutting edge, cutting the filament bundle wound on the cutter disc. The triangular shape of the cutting edge portion prevents breakage when cutting long filament bundles.

[0004] However, this technical solution has the following shortcomings: the tool fixation can only be used for fibers of one hardness type, and cannot adapt to different fiber materials, thicknesses and cutting process requirements. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic and efficient short fiber forming device. By installing a coarse blade and a fine blade with adjustable position on a rotating cutter head, the device can meet the requirements of different fiber materials, thicknesses, and cutting processes, thereby improving its adaptability to diverse fibers and reducing the time and cost associated with replacing the entire set of blades.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic and efficient short fiber forming device, including a rotating cutter disc, a pressure plate is provided on one side of the rotating cutter disc, and a tensioning mechanism is provided on the other side of the rotating cutter disc. A coarse blade and a fine blade are installed on the rotating cutter disc, and the fine blade can be moved and adjusted on the rotating cutter disc to quickly cut and form short fibers corresponding to fiber bundles of different hardness materials.

[0007] As an improvement, a mounting groove is provided on the side wall of the rotating cutter head, and the coarse cutter is fixedly installed in the mounting groove; a sliding groove is also provided on the side wall of the rotating cutter head, and the fine cutter is slidably installed in the sliding groove.

[0008] As an improvement, the mounting groove and the sliding groove are alternately arranged at equal angles.

[0009] As an improvement, a mounting hole is provided at the top center of the rotary cutter head, and the mounting hole penetrates the partial mounting position of the slide groove; an adjustment block is detachably installed in the mounting hole.

[0010] As an improvement, a guide surface is provided on the top of the blade mounting side.

[0011] As an improvement, when the adjusting block is installed in the mounting hole, the bottom of the adjusting block extends beyond the lowest point of the guide surface.

[0012] As an improvement, the bottom of the adjustment block is provided with a groove, and the top is provided with a handle.

[0013] As an improvement, the rotating cutter head is provided with a through hole above the slide groove, and the through hole penetrates into the slide groove; the top of the fine blade is provided with a first insertion hole and a second insertion hole; a fixing component is detachably installed in the insertion hole.

[0014] As an improvement, threads are provided on the first insertion hole, the second insertion hole, and the fixing member.

[0015] As an improvement, a handle is provided on the top of the fastener.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By setting a fixed coarse knife and an adjustable fine knife on the rotating cutter disc, this utility model can quickly call the appropriate cutter for processing different fiber materials, which has a wide range of applications, saves the cost of preparing multiple models of equipment, and also reduces unnecessary wear and tear on the cutter.

[0018] (2) This utility model uses an adjustment block to quickly adjust the fine blade by using the mounting hole. After the adjustment block is installed, all the fine blades are simultaneously extended into place, which improves the blade changing efficiency. At the same time, it also provides some support for the fine blades during the processing, maintains the stability of the blades, and improves the cutting quality of short fibers.

[0019] (3) By setting through holes on the rotating cutter head and inserting holes on the fine blade, and with the help of fixing parts, this utility model can further fix the fine blade when it extends and retracts, reduce the vibration of the cutter, improve stability, and ensure cutting accuracy.

[0020] In summary, this utility model has the advantages of wide applicability, high cutting quality, fast tool changing efficiency, and good stability. Attached Figure Description

[0031] Example 1

[0032] like Figures 1 to 7 As shown, this embodiment provides an automatic and efficient short fiber forming device, including a rotating cutter head 1. A pressure plate 2 is provided on one side of the rotating cutter head 1, and a tensioning mechanism 3 is provided on the other side of the rotating cutter head 1. A coarse blade 11 and a fine blade 12 are installed on the rotating cutter head 1. The fine blade 12 can be moved and adjusted on the rotating cutter head 1 to quickly change blades to cut and form short fibers corresponding to fiber bundles of different hardness materials.

[0033] Specifically, the fiber filaments are wound onto the rotating cutter head 1 after tension adjustment at the tensioning mechanism 3, and rotate with the rotating cutter head 1. As the fiber filaments wound on the rotating cutter head 1 become thicker, when their thickness is greater than the thickness of the pressure plate 2 and the rotating cutter head, the innermost fiber filaments are squeezed by the pressure plate 2 and cut into short fibers by the blades.

[0034] like Figure 2 As shown, the rotating cutter head 1 has a mounting groove 13 on its side wall, and the coarse cutter 11 is fixedly installed in the mounting groove 13; the rotating cutter head 1 also has a sliding groove 14 on its side wall, and the fine cutter 12 is slidably installed in the sliding groove 14.

[0035] It is worth mentioning that by setting the sliding fine blade 12, when dealing with coarse and hard fibers, the fine blade 12 is kept in a retracted state, so that the thick-edged coarse blade 11 group is on the outermost layer and wraps around the coarse and hard fibers; when dealing with fine and soft fibers, the fine blade 12 is extended, so that the thin-edged and sharp fine blade 12 group is on the outermost layer and wraps around the fine and soft fibers.

[0036] like Figure 2As shown, the mounting groove 13 and the sliding groove 14 are alternately arranged at equal angles.

[0037] In this way, when the short fibers are cut at equal angles using a single set of blades, the produced short fibers can maintain the set length, ensuring the consistency and precision of the short fibers under cutting and shaping.

[0038] like Figure 3 As shown, a mounting hole 15 is provided at the top center of the rotating cutter head 1, and the mounting hole 15 penetrates the partial mounting position of the slide groove 14; an adjusting block 4 is detachably installed in the mounting hole 15.

[0039] It is understandable that the outer diameter of the adjusting block 4 is set in a similar shape to the diameter of the mounting hole 15, so that the mounting hole 15 can play a limiting and guiding role for the adjusting block 4, and the installation of the adjusting block 4 can be completed simply and conveniently.

[0040] After the adjustment block 4 is installed, all the fine blades 12 are simultaneously extended into place, improving the efficiency of switching blade sets. At the same time, it also provides some support for the fine blades 12 during processing, maintaining the stability of the blades and improving the cutting quality of short fibers.

[0041] like Figure 7 As shown, a guide surface 121 is provided on the top of the mounting side of the fine knife 12.

[0042] The advantage of this design is that it allows the adjusting block 4 to contact the fine blade 12 during the process of entering the mounting hole 15, and to simultaneously extend the fine blade 12 into place. This avoids direct friction between the adjusting block 4 and the mounting side of the fine blade 12, which would cause wear and tear, and also saves the time required to manually adjust the fine blade 12.

[0043] like Figure 3 As shown, when the adjusting block 4 is installed in the mounting hole 15, the bottom of the adjusting block 4 exceeds the lowest position of the guide surface 121.

[0044] Combination Figure 2 After the adjustment block 4 is installed, its side wall contacts the vertical surface 124 of the mounting side of the fine blade 12, which provides a certain support for the fine blade 12 during the processing, maintains the stability of the blade, and improves the cutting quality of short fibers.

[0045] like Figure 3 As shown, the bottom of the adjusting block 4 has a groove 41 and the top has a handle 42.

[0046] It is worth mentioning that the groove 41 can effectively reduce the weight of the adjusting block 4, making it easier for production personnel to use the adjusting block 4. The top handle 42 further improves the convenience for production personnel, allowing them to hold it with one hand for transfer.

[0047] like Figure 6 As shown, the rotating blade 1 is provided with a through hole 16 above the slide groove 14, and the through hole 16 penetrates into the slide groove 14; the top of the fine blade 12 is provided with a first insertion hole 122 and a second insertion hole 123; a fixing member 5 is detachably installed in the insertion hole 16.

[0048] It should be noted that when the set of 12 thin blades is in the extended state, the fixing member 5 passes through the through hole 16 and is inserted into the second insertion hole 123 for fixing; when the set of 12 thin blades is in the retracted state, the fixing member 5 passes through the through hole 16 and is inserted into the first insertion hole 122 for fixing.

[0049] like Figure 7 As shown, the first insertion hole 122, the second insertion hole 123, and the fixing member 5 are all provided with threads.

[0050] Here, the threaded fastener 5 can lock when inserted into the socket, further improving the stability of the fine blade 12 in both states, reducing blade vibration, and ensuring cutting accuracy.

[0051] like Figure 6 As shown, a handle 51 is provided on the top of the fastener 5. This facilitates manual tightening of the fastener 5 by production personnel.

[0052] Work steps

[0053] When producing coarse and stiff fibers, the adjusting block 4 is not installed in the mounting hole 15, the fine blade 12 is in a retracted state, and the fixing piece 5 is locked in the first insertion hole 122. The fiber filaments are wound around the coarse blade 11 of the rotating cutter disc 1 after the tension mechanism 3 is adjusted by tension, and at the same time, they rotate with the rotating cutter disc 1. As the fiber filaments wound on the rotating cutter disc 1 become thicker, when its thickness is greater than the thickness of the pressure plate 2 and the rotating cutter disc, the innermost fiber filaments are squeezed by the pressure plate 2 and cut into short fibers by the blade.

[0054] When producing fine and soft fibers, loosen and remove the fixing piece 5, place the adjusting block 4, extend the fine blade 12, lock the fixing piece 5 in the second insertion hole 123, the fiber filaments are wrapped around the fine blade 12, and are cut into short fibers by the blade.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
