[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0030] As shown in the figure, an adjustable drafting device for fibers includes: a supporting mechanism, a drafting mechanism disposed inside the supporting mechanism, and an adjusting mechanism disposed on one side of the drafting mechanism.

[0031] It should be noted that the supporting mechanism is arranged on both sides of the drafting mechanism to support the entire equipment, and the fiber bundle passes through the drafting mechanism for drafting operation. At this time, the adjusting mechanism adjusts the speed of the drafting mechanism to adjust the drafting force on the fiber bundle.

[0032] The support mechanism includes: a plurality of support plates; the support plates are symmetrically arranged vertically, a motor box is provided on one side of the support plate, a motor is provided inside the motor box, and the motor is used to drive the main drafting roller; a rotating plate is rotatably connected to the support plate, and the rotating plate is fixedly connected to the main drafting roller;

[0033] It should be noted that there are two support plates and they are symmetrically arranged on both sides of the drafting mechanism. The rotating plate and the motor are respectively arranged on the two support plates and at both ends of the active roller.

[0034] The drafting mechanism includes: a main drafting roller and an auxiliary drafting roller; an adjusting mechanism is provided at one end of the main drafting roller for adjusting the speed of the main drafting roller; the main drafting roller is provided on one side of the auxiliary drafting roller, and the adjusting mechanism is provided on the inner side of the main drafting roller;

[0035] In the utility model, the main drafting roller includes an active roller and a driven roller; the middle of the active roller is hollow, and the adjustment mechanism is arranged in the hollow; the auxiliary drafting roller includes an upper drafting roller and a lower drafting roller; the upper drafting roller and the lower drafting roller are both rotatably connected to the support plate; one end of the active roller and the driven roller are fixedly connected to a gear ring, and the gear rings on the active roller and the driven roller are both arranged in a meshing shape.

[0036] It should be noted that the driven roller includes several upper drafting rollers and several lower drafting rollers. The two ends of the upper drafting rollers are rotatably connected to the top of the support plate, and the lower drafting rollers are rotatably connected to the bottom of the support plate. The upper drafting rollers and the lower drafting rollers are staggered and placed alternately, that is, there is only one driven roller in a vertical plane. The driven roller is opened from one end of the support plate, which means that this end is set as the starting end and the other end is the end end. There are several groups of driven rollers. On the last group of driven rollers, only the lower drafting roller is set, and the main drafting roller is set at the position of the upper drafting roller of the last group of driven rollers.

[0037] During operation, the fiber tow passes around the bottom of the lower drafting roller at the starting end, is pulled to the top of the adjacent upper drafting roller, and passes around from the top, is pulled to a lower drafting roller, and passes around from the bottom until it is pulled to the main drafting roller and passes through the main drafting roller. The rotation of the main drafting roller acts on the fiber tow.

[0038] The main drafting roller includes an active roller and a driven roller, and gear rings fixedly connected to the active roller and the driven roller respectively. The gear ring on the active roller and the gear ring on the driven roller are in a meshing state. When the motor drives the active roller to rotate through the drive shaft, the driven roller is driven to rotate through the previous meshing of the gear rings, and the active roller and the driven roller rotate in opposite directions, so that after the fiber bundle passes between the active roller and the driven roller, as the motor drives the two, the active roller and the driven roller move in opposite directions, and the fiber bundle is pulled forward by clamping and moving in opposite directions, thereby performing a drafting operation on the fiber bundle.

[0039] The adjustment mechanism includes: a drive shaft, several gear ring groups arranged on the drive shaft, and an adjustment rod fixedly connected to the gear ring groups; one end of the drive shaft is fixedly connected to the motor, and the other end is fixedly connected to the rotating plate; the drive shaft and the gear ring group are fixedly connected by a clamp.

[0040] In the utility model, there are three groups of gear ring groups, namely the first gear ring group, the second gear ring group and the third gear ring group. The gear ring groups of each group have the same structure but different gear ratios; the first gear ring group includes an outer gear ring and an inner gear ring meshing with the outer gear ring; the teeth of the inner gear ring are arranged on the inner side of the circular ring, and the teeth of the outer gear ring are arranged on the outer side of the circular ring; the inner gear ring is fixedly connected to the active roller; the clamping member includes a fixing member and a spring; a number of clamping grooves are provided on the drive shaft, and a number of placement grooves are provided on the outer gear ring; the spring and the fixing member are both arranged in the placement groove, and the two ends of the spring are fixedly connected to the fixing member and the placement groove respectively; the adjusting rod is U-shaped, the adjusting rod is fixedly connected to the gear ring group, and the rotating plate is slidably connected to the adjusting rod; the adjusting rod is U-shaped, the adjusting rod is fixedly connected to the outer gear ring, and the outer gear ring is clamped to the drive shaft through the clamping member, or slides in the axial direction of the drive shaft; each group of gear ring groups has only one outer gear ring meshing with the inner gear ring.

[0041] It should be noted that the inner side of the active roller is hollow and the gear ring group, drive shaft, and adjustment rod are all set on the inner side of the active roller. The gear ring group is provided with three groups: the first gear ring group, the second gear ring group, and the third gear ring group. Since the gear ratios of the three gear ring groups are different, the three gear ring groups will produce different speeds when they are engaged. By adjusting the gear ratios between the inner gear ring and the outer gear ring that meshes with each other in each of the three gear ring groups, different speeds are produced when the outer gear rings mesh with their corresponding inner gear rings during operation.

[0042] The driving shaft is arranged on the inner side of the hollow of the active roller, and a plurality of slots are opened on the driving shaft. The outer gear ring in the gear ring group is sleeved on the driving shaft, and a placement groove is opened on the inner side of the outer gear ring. A fixing piece is slidably connected in the placement groove. A spring is arranged between the fixing piece and the outer gear ring. Both ends of the spring are fixedly connected to the outer gear ring and the fixing piece. The cross section of the fixing piece is formed by a combination of a triangle and a rectangle. The rectangular part at the bottom is slidably connected to the outer gear ring, and the triangular part at the top is connected to the slot on the driving shaft. The shape of the slot is the same as that of the fixing piece. When the outer gear ring is subjected to force and moves axially along the driving shaft, the setting direction of the fixing piece can make the fixing piece The fixing part is squeezed with the inclined surface on the slot, decomposing the force into an inclined upward thrust, thereby compressing the spring and pushing the fixing part into the placement slot, so that the outer ring gear is disengaged. Simply put, the direction in which the fixing part is set is that when the outer ring gear is pushed by external force, the two inclined surfaces in the axial direction will produce squeezing, thereby enabling the fixing part to squeeze the spring, thereby enabling the fixing part to retract into the placement slot of the drive shaft and move the outer ring gear. When the outer ring gear rotates, the vertical plane of the fixing part and the vertical plane of the slot are squeezed. Since both are vertical planes, the fixing part cannot be retracted.

[0043] The adjusting rod is set in a U shape, and the U-shaped vertical rods on both sides are fixedly connected to the outer gear rings of the first gear ring group, the second gear ring group and the third gear ring group respectively. The U-shaped bottom of the adjusting rod is set in a handle shape on the outside of the active roller, and on the inside of the active roller, the three inner gear rings are evenly set on the inside of the active roller, and the outer gear rings are unevenly distributed. When the adjusting rod completely enters the inside of the active roller and only the bottom is left on the outside, the outer gear ring of the adjusting rod is just fixed on the last slot, and the outer gear ring of the outermost gear ring is meshed with the outermost inner gear ring. At this time, the distance between the middle inner gear ring and the middle outer gear ring is 5 cm, which is also the distance between the slots. The distance between the innermost inner gear ring and the innermost outer gear ring is 10 cm. When it is necessary to adjust to other speeds, by pulling the adjusting rod, an external force is applied to the outer gear ring to move the inner gear ring, thereby making different gear ring groups mesh, but only one gear ring group is always meshed, thereby adjusting the speed.

[0044] During operation, the fiber bundle is passed through the auxiliary drafting roller farthest from the active roller, and finally passes between the active roller and the driven roller. Then the motor is started to make the active roller and the driven roller rotate towards each other, squeezing and stretching the fiber bundle, and by adjusting the speed, different drafting forces are generated.

[0045] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
