Description

Technical Field

[0001] This invention relates to a take-up roller for a carding machine, belonging to the field of carding machine technology. Background Technology

[0002] There are many types of carding machines, such as opening and carding integrated machines and random opening and carding integrated machines. These carding machines all have a take-up roller, which is basically a cylindrical body with a wooden structure, and some of the cylinders also have a cutting groove for easy cutting.

[0003] Specifically, the existing technologies retrieved are as follows: Publication (Announcement) No.: CN211036208U discloses a cotton opening and combing machine, which discloses a cotton winding roller 5, and the cotton winding roller 5 has a groove 501 on it for easy cutting.

[0004] Publication (Announcement) No.: CN113201811A discloses a low-speed, high-yield random carding machine for nonwoven fibers. The rear end of the frame 1 is provided with a cotton roll 3, and the frame 1 is provided with a cutter assembly 23 above the cotton roll 3, which can slide along the axis of the cotton roll.

[0005] Publication (Announcement) No.: CN115559026A A thousand-layer cotton combing and impurity removal device, wherein the combing machine body 1 is rotatably connected to the winding drum 3 in the cotton outlet direction, and the sliver is discharged from the cotton outlet of the combing machine body 1 and then connected to the winding drum 3.

[0006] As can be seen from the existing technologies described above, although the existing take-up rollers have different names, their function is the same: to wind up the cotton wick. In quilt making, the commonly used size is 1.8 meters wide, but the length varies depending on the user's height, ranging from 1.8 meters to 2.6 meters, which is a common requirement. However, the diameter of the take-up roller itself is fixed. This leads to inconsistent quality of the cotton wick when using different sizes of take-up rollers. Furthermore, the process of changing to take-up rollers of different diameters is complex due to the connection of the drive mechanism, requiring specialized equipment. Ordinary users cannot easily perform such changes, making it impossible for users to guarantee the quality of cotton wicks of different lengths. Summary of the Invention

[0007] In view of the above-mentioned problems existing in the prior art, the main objective of the present invention is to provide a take-up roller for a carding machine, the diameter of which can be adjusted according to customer needs to ensure the quality of the cotton core.

[0008] The technical solution provided by the present invention is: a take-up roller for a carding machine includes a central shaft, toothed discs fixedly installed on both sides of the central shaft, a fixed disc bearing installed on the central shaft outside the toothed discs, and two variable diameter discs respectively sleeved on the fixed disc bearing on one side; The variable diameter disc includes a fixed disc with several fixed disc support arms extending along the radial direction. A limiting groove is provided on the fixed disc support arm. The movable arm is slidably sleeved on the fixed disc support arm. A limiting block is installed on the side of the movable arm located in the limiting groove, and a limiting roller is installed on the side opposite to the limiting block. The limiting roller is located in the arc-shaped limiting groove provided on the surface of the gear disc. An arc-shaped support plate is installed on the top of the boom. A positioning connecting rod is installed between two arc-shaped support plates that are opposite each other along the central axis. A circular arc roller plate is installed on the outside of the positioning connecting rod. One of the adjacent sides of the adjacent circular arc roller plates is located below or above the other, and together they form the circumference of the winding roller. Fan-shaped roller side plates are installed on the side of the arc-shaped support plate, with one side of an adjacent fan-shaped roller side plate located below or above the other side, and together they form the roller side of the take-up roller. Rotary rod fixing arms are symmetrically installed on one side of the upper part of the two fixed plate support arms opposite the two variable diameter discs. A drive gear is rotatably installed on each of the two rotary rod fixing arms. The two drive gears are connected by a linkage shaft. Both drive gears are engaged with the gear disc on their respective sides. A drive rod is installed on the opposite side of one of the drive gear installation sides. The drive rod is connected to one end of the linkage shaft.

[0009] The drive rod and linkage shaft drive two drive gears to mesh and rotate with the gear discs on their respective sides. The arc-shaped limiting groove of the gear disc drives the limiting roller to rotate and move along the arc-shaped limiting groove, thereby causing the boom to extend or retract. When it retracts to the bottom of the arc-shaped limiting groove, the diameter of the take-up roller is the smallest, and when it extends to the top of the arc-shaped limiting groove, the diameter of the take-up roller is the largest.

[0010] Furthermore, a central shaft retaining ring plate is also installed on the outside of the roller side plate, which is sleeved on the fixed plate bearing and fixed to the fixed plate with bolts. The central shaft retaining ring plate is used to cover the voids generated when the inner rings of the multiple roller side plates that form the side of the roller move and change diameter.

[0011] Furthermore, the head of the drive rod is configured as an inner angle bolt or an outer bolt head, which is driven by a sleeve or wrench matched with the inner angle bolt or the outer bolt head. A drive stroke groove is opened on the roller side plate on the side where the drive rod is located.

[0012] Furthermore, the rotating rod fixing arm located on one side of the drive rod has a positioning mechanism on the side of the rotating rod fixing arm facing the gear plate surface.

[0013] Furthermore, the positioning mechanism includes a positioning plate and ball-type positioning pins mounted on the positioning plate. Positioning grooves are spaced apart on the surface of the gear plate, and a scale value for the roller diameter is set on the outer surface of the roller side plate corresponding to the drive rod. The scale value corresponds to the position of the positioning groove. There are many types of positioning mechanisms, such as locking mechanisms for gear plates, but if the goal is to calibrate the scale so that the user knows the size of the roller diameter, a positioning mechanism using ball-type positioning pins is the simplest and most effective.

[0014] Furthermore, the fixed plate support arm is provided with 8 arms, and the corresponding movable arm sleeved on it is also provided with 8 arms. The arc-shaped limiting slide groove on the toothed plate is provided with 8 corresponding slots, and the arc-shaped roller plate and the fan-shaped roller side plate are provided with 8 pieces respectively.

[0015] Furthermore, the positioning connecting rods connecting the arc-shaped support plates are set with 10 to 24 rods. When 10 rods are set, one rod is connected to the middle of the arc-shaped support plate, and two rods are located at the sealing point (that is, when the diameter is at its minimum, the two positioning connecting rods installed on the adjacent sides of the adjacent arc-shaped support plates are close together to form a stable cylinder). When 24 rods are set, three rods are connected to each arc-shaped support plate, including one rod in the middle and two rods on both sides.

[0016] Furthermore, the arc-shaped support plate has clearance steps in the middle and at both ends, and the end of the positioning connecting rod is welded to the clearance step. The top surface of the positioning connecting rod and the top surface of the clearance step are on the same plane.

[0017] Furthermore, an arc-shaped plug is welded to the upper part of the outer side surface of the arc-shaped support plate.

[0018] Furthermore, both ends of the arc-shaped roller plate are provided with pressing edges, which press against the top of the fan-shaped roller side plate.

[0019] The advantages of this invention over the prior art are as follows: 1. Multi-size diameter adjustment has been achieved to meet customer needs; 2. The structure is stable and easy to adjust and lock in size. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0023] like Figure 1-3 The illustrated take-up roller for a carding machine includes a central shaft 1, toothed discs 2 fixedly mounted on both sides of the central shaft 1, a fixed bearing 4 mounted on the central shaft outside the toothed discs 2, and two variable diameter discs 3 respectively sleeved on the fixed bearing 4 on one side. Each variable diameter disc 3 includes a fixed disc 31 with eight fixed disc support arms 32 extending radially. Limiting grooves 33 are provided on the fixed disc support arms 32. Movable arms 34 are slidably sleeved on the fixed disc support arms 32. There are eight fixed disc support arms, and correspondingly eight movable arms are also sleeved on them. A limiting block is installed on the side of the movable arm 34 located within the limiting groove 33, and a limiting roller 35 is installed on the side opposite the limiting block. The limiting roller 35 is located in an arc-shaped limiting groove 36 provided on the toothed disc surface. There are eight corresponding arc-shaped limiting grooves 36 on the toothed disc surface. An arc-shaped support plate 37 is installed on the top of the boom 34. A positioning connecting rod 5 is installed between two arc-shaped support plates 37 that are opposite each other along the central axis. An arc-shaped roller plate 6 is installed on the outside of the positioning connecting rod 5. One of the adjacent sides of the adjacent arc-shaped roller plates 6 is located below or above the other, and together they form the circumference of the winding roller.

[0024] A fan-shaped roller side plate 7 is installed on the side of the arc-shaped support plate 37. One side of the adjacent fan-shaped roller side plate 7 is located below or above the other side, and together they form the roller side of the winding roller.

[0025] Eight pieces of each are provided for the arc-shaped roller plate 6 and the fan-shaped roller side plate 7.

[0026] It should be noted that the arc length of the circular arc roller plate 6 is greater than the arc length after the roller is divided on average when the roller diameter is at its maximum. This ensures that when adjusted to the maximum, the edges of the adjacent circular arc roller plates are still pressed together as designed, and the cylinder remains cylindrical without gaps.

[0027] A rotating rod fixing arm 8 is symmetrically installed on one side of the upper part of each of the two fixed plate support arms 32 opposite to the two reducing discs 3. A drive gear 9 is rotatably mounted on each of the two rotating rod fixing arms 8. The two drive gears 9 are connected by a linkage shaft 10. Both drive gears 9 engage with the gear disc 2 on their respective sides. A drive rod 11 is set on the opposite side of one of the drive gears 9, and the drive rod 11 is connected to one end of the linkage shaft 10. The head of the drive rod 11 is set with an internal hex bolt head structure, and is driven by an internal hex wrench. A drive stroke groove is opened on the roller side plate 7 on the side where the drive rod 11 is located.

[0028] The rotating rod fixing arm 8 located on one side of the drive rod 11 has a positioning mechanism 12 on the side facing the gear plate. The positioning mechanism 12 includes a positioning plate and a ball positioning pin mounted on the positioning plate. Positioning grooves 13 are provided at intervals on the gear plate. The roller diameter scale value 14 is provided on the outer surface of the roller side plate 7 corresponding to the drive rod 11. The scale value corresponds to the position of the positioning groove 13.

[0029] In this embodiment, the cylinder diameter ranges from 70cm to 80cm, with several settings in between: 72cm, 74cm, 76cm, and 78cm.

[0030] The tube diameter refers to the diameter of the tube. When the tube diameter is 70cm, the circumference is 219.91cm, approximately 2.2 meters. However, when cut with a cutter, the actual corresponding cotton core is 2 meters. The same principle applies to the others.

[0031] A central shaft retaining ring plate 15 is also installed outside the roller side plate 7, which is sleeved on the fixed plate bearing 4 and fixed to the fixed plate with bolts.

[0032] Both ends of the arc roller plate 6 are provided with pressing edges 16, which press the top of the fan-shaped roller side plate 7. Example

[0033] Based on Embodiment 1, the arc-shaped support plate 37 has clearance steps in the middle and at both ends. The end of the positioning connecting rod 5 is welded to the clearance step, and the top surface of the positioning connecting rod 5 and the top surface of the clearance step are on the same plane.

[0034] like Figure 3As shown, there are 17 positioning connecting rods 5 connecting the arc-shaped support plate 37, including one connected in the middle of the arc-shaped support plate, totaling 8 rods. There are also 8 positioning connecting rods 5 set on the clearance step on one side of the arc-shaped support plate. Another rod is set on the clearance step on the other side of one of the arc-shaped support plates, forming a sealing limit. That is, when the diameter is at its minimum, the two positioning connecting rods installed on the adjacent sides of the adjacent arc-shaped support plates are close together to form a stable cylinder. Example

[0035] Based on Embodiment 1, the arc-shaped support plate 37 has clearance steps in the middle and at both ends. The end of the positioning connecting rod 5 is welded to the clearance step, and the top surface of the positioning connecting rod 5 and the top surface of the clearance step are on the same plane.

[0036] There are 24 positioning connecting rods 5 connecting the arc-shaped support plate 37, with three rods connected to each arc-shaped support plate, including one in the middle and two other rods on both sides.

[0037] An arc-shaped blocking block is welded to the upper part of the outer side of the arc-shaped support plate 37. This block is used to block the end face of the positioning connecting rod 5 and to provide a foundation for the roller side plate 7 to be mounted on a plane.

[0038] An inward groove is provided on one of the arc-shaped roller plates 6, positioned to avoid the positioning connecting rod 5, for cutting. A corresponding notch is opened on the top of the corresponding fan-shaped roller side plate 7.

[0039] The above embodiments are used to illustrate that this application can have many modifications and cannot be used to limit the scope of protection of this application. Any modifications made by any other person based on this and in combination with the prior art are within the scope of protection of this application.
