Description

Technical Field

[0001] This utility model belongs to the field of glass fiber processing technology and relates to a yarn ball paper tube peeling mechanism. Background Technology

[0002] Chinese patent discloses a paper tube and yarn extraction device [application publication number CN115806224A], which includes a frame, on which are installed a yarn roll positioning mechanism, a paper tube extraction mechanism, a yarn extraction and cutting mechanism, and a paper tube packing mechanism. The yarn roll positioning mechanism is used to clamp and position the yarn roll, the paper tube extraction mechanism is used to extract the paper tube from the yarn roll, the yarn extraction and cutting mechanism is used to gather, cut, and peel the yarn, and the paper tube packing mechanism is used to place the paper tube in the packing position on the paper tube shelf.

[0003] The paper tube extraction mechanism includes a paper tube internal support mechanism, a paper tube clamping mechanism, and a paper tube peeling mechanism. The paper tube clamping mechanism includes two pneumatic fingers and two clamping cylinders. The piston rods of the clamping cylinders are fixedly connected to the pneumatic fingers. The pneumatic fingers clamp the upper sides of the paper tube and, under the action of the clamping cylinders, drive the upper end of the paper tube to move inward, achieving partial peeling of the yarn roll (yarn ball) from the upper end of the paper tube. During the peeling action, the two clamping cylinders operate synchronously, causing the two pneumatic fingers to move inward synchronously. This can cause interference, resulting in a smaller peeling space between the paper tube and the yarn ball. Additionally, due to the influence of the two pneumatic fingers, the distance between the two peeling plates is larger, which cannot guarantee complete peeling of the paper tube from the yarn ball. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a yarn-paper tube separation mechanism that allows the paper tube to be completely separated from the yarn bundle.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A yarn ball paper tube peeling mechanism includes a mounting frame, a first clamping structure for clamping the upper side of the paper tube, a second clamping structure opposite to the first clamping structure, a first driving member mounted on the mounting frame for driving the first clamping structure to move inward, and a second driving member for driving the second clamping structure to move inward. The first driving member and the first clamping structure enable the paper tube and the yarn ball to form a first peeling space, and the second driving member and the second clamping structure enable the paper tube and the yarn ball to form a second peeling space. A first rotating rod and a second rotating rod are vertically slidably mounted on the mounting frame. The first rotating rod is located directly above the first peeling space, and the second rotating rod is located directly above the second peeling space. The mounting frame is also provided with a driving cylinder for driving the first rotating rod and the second rotating rod to move up and down synchronously, and a driving structure for driving the first rotating rod and the second rotating rod to rotate synchronously. The lower end of the first rotating rod is provided with a vertically extending first peeling rod that is not coaxial, and the lower end of the second rotating rod is provided with a vertically extending second peeling rod that is not coaxial.

[0007] The working process of this yarn ball paper tube peeling mechanism is as follows: The mounting frame descends, the first clamping structure clamps the upper side of the paper tube, and the second clamping structure clamps the other side of the upper end of the paper tube. The first driving member drives the first clamping structure to move inward, and the second driving member drives the second clamping structure to move inward, forming the first peeling space and the second peeling space. Subsequently, the first peeling rod and the second peeling rod extend into the first peeling space and the second peeling space respectively under the action of the driving cylinder. Under the action of the driving structure, the first rotating rod and the second rotating rod rotate, and the paper tube is separated from the yarn ball by the first peeling rod and the second peeling rod.

[0008] In the above-mentioned yarn ball paper tube peeling mechanism, the piston rod of the driving cylinder is fixedly connected to the mounting frame, and a mounting flange is fixedly connected to the driving cylinder. The upper ends of the first rotating rod and the second rotating rod are rotatably mounted on the mounting flange. The driving structure is mounted on the mounting flange, and a vibration motor is mounted on the mounting flange.

[0009] The mounting bracket is in a fixed state. When the drive cylinder is activated, the cylinder body moves up and down, thereby driving the mounting flange, the first rotating rod, the second rotating rod, and the drive structure to move up and down.

[0010] In the aforementioned yarn ball paper tube peeling mechanism, the drive structure includes a drive motor fixed to the mounting flange, a drive wheel coaxially fixed to the drive motor's shaft, a first driven wheel coaxially fixed to a first rotating rod, and a second driven wheel coaxially fixed to a second rotating rod. The drive wheel, the first driven wheel, and the second driven wheel are connected by a gear / chain / belt transmission. When the drive motor operates, it drives the drive wheel to rotate, and the drive wheel drives the first and second driven wheels to rotate synchronously via gears / chains / belts. When the transmission is via gears, the drive wheel, the first driven wheel, and the second driven wheel are gears; when the transmission is via chains, the drive wheel, the first driven wheel, and the second driven wheel are sprockets; and when the transmission is via belts, the drive wheel, the first driven wheel, and the second driven wheel are belt pulleys.

[0011] In the above-mentioned yarn ball paper tube peeling mechanism, the lower end of the first rotating rod is connected to the top end of the first peeling rod through a horizontally extending first connecting rod, and the lower end of the second rotating rod is connected to the top end of the second peeling rod through a horizontally extending second connecting rod.

[0012] The rotation range of the first and second peeling rods is increased by the first connecting rod / second connecting rod. The first and second peeling rods extend vertically, which increases the contact area with the paper tube and makes it easier to peel the paper tube from the yarn bundle.

[0013] In the above-mentioned yarn ball paper tube peeling mechanism, the first driving member is a first cylinder mounted on the mounting frame. The first cylinder extends radially inward and downward along the paper tube. The piston rod of the first cylinder is provided with a first mounting seat, and the first clamping structure is provided on the first mounting seat. The second driving member is a second cylinder mounted on the mounting frame. The second cylinder extends radially inward and downward along the paper tube. The piston rod of the second cylinder is provided with a second mounting seat, and the second clamping structure is provided on the second mounting seat.

[0014] The first cylinder and the second cylinder are arranged opposite each other, and their piston rods can extend inward and downward in the radial direction of the paper tube at the same time, thereby driving the first clamping structure and the second clamping structure to move closer to each other, so that the two opposite sides of the upper end of the paper tube tilt inward and downward.

[0015] In the aforementioned paper roll peeling mechanism, the piston rod of the first cylinder makes an angle of 5° to 30° with the horizontal plane, and the piston rod of the second cylinder also makes an angle of 5° to 30° with the horizontal plane. The 5° to 30° angle between the piston rods of the first and second cylinders and the horizontal plane facilitates the inward and downward tilting of the upper side of the paper roll. The size of this angle depends on the diameter of the paper roll; the larger the diameter, the larger the angle.

[0016] In the above-mentioned yarn ball paper tube peeling mechanism, the first clamping structure is a first finger, which has a first claw and a second claw. The first claw and the second claw work together to clamp the upper side of the paper tube. The length of the first claw is greater than half the depth of the paper tube.

[0017] The first and second grippers can be pneumatic or electric.

[0018] In the above-mentioned yarn ball paper tube peeling mechanism, the second clamping structure is a second finger, which has a third claw and a fourth claw. The third claw and the fourth claw work together to clamp the upper side of the paper tube. The length of the third claw is greater than half the depth of the paper tube.

[0019] The third and fourth grippers can be pneumatic or electric.

[0020] Compared with existing technologies, this yarn ball paper tube peeling mechanism has the following advantages:

[0021] Because the first peeling rod and the first rotating rod are not coaxial, the first peeling rod rotates more when the first rotating rod rotates, resulting in a more thorough separation of the paper tube from the yarn bundle. Similarly, because the second peeling rod and the second rotating rod are not coaxial, the second peeling rod rotates more when the second rotating rod rotates, resulting in a more thorough separation of the paper tube from the yarn bundle. The inward and downward movement of the first and second clamping structures is in the same direction as the inward tilt of the upper end of the paper tube, making it difficult for the upper side of the paper tube to detach from the first / second clamping structure. Furthermore, this prevents debris from the paper tube from entering the gap between the first / second clamping structure and the paper tube when relative sliding occurs, thus preventing a decrease in clamping force.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1The paper roll peeling mechanism shown includes a mounting frame 1, a first clamping structure for clamping the upper side of the paper roll, a second clamping structure disposed opposite to the first clamping structure, a first driving member disposed on the mounting frame 1 for driving the first clamping structure to move inward, and a second driving member for driving the second clamping structure to move inward.

[0026] In this embodiment, the first driving member is a first cylinder 10 mounted on the mounting frame 1. The first cylinder 10 extends radially inward and downward along the paper tube. The piston rod of the first cylinder 10 is provided with a first mounting seat, and a first clamping structure is provided on the first mounting seat. The second driving member is a second cylinder 11 mounted on the mounting frame 1. The second cylinder 11 extends radially inward and downward along the paper tube. The piston rod of the second cylinder 11 is provided with a second mounting seat, and a second clamping structure is provided on the second mounting seat.

[0027] The first cylinder 10 and the second cylinder 11 are arranged opposite to each other. Their piston rods can extend inward and downward along the radial direction of the paper tube at the same time, thereby driving the first clamping structure and the second clamping structure to move closer to each other, so that the two opposite sides of the upper end of the paper tube tilt inward and downward.

[0028] The piston rod of the first cylinder 10 makes an angle of 5° to 30° with the horizontal plane, and the piston rod of the second cylinder 11 makes an angle of 5° to 30° with the horizontal plane. The size of this angle depends on the diameter of the paper tube; the larger the diameter of the paper tube, the larger the angle. In this embodiment, the piston rods of the first cylinder 10 and the second cylinder 11 both form a 25° angle with the horizontal plane.

[0029] like Figure 1 As shown, the first clamping structure is a first finger 12, which has a first claw 13 and a second claw 14. The first claw 13 and the second claw 14 work together to clamp the upper side of the paper tube. The length of the first claw 13 is greater than half the depth of the paper tube. The second clamping structure is a second finger 15, which has a third claw 16 and a fourth claw 17. The third claw 16 and the fourth claw 17 work together to clamp the upper side of the paper tube. The length of the third claw 16 is greater than half the depth of the paper tube.

[0030] The first finger (12) can be either pneumatic or electric. The second finger (15) can also be either pneumatic or electric.

[0031] The first driving member and the first clamping structure enable the paper tube and the yarn bundle to form a first separation space, and the second driving member and the second clamping structure enable the paper tube and the yarn bundle to form a second separation space. Figure 1As shown, a first rotating rod 2 and a second rotating rod 3 are vertically slidably mounted on the mounting frame 1. The first rotating rod 2 is located directly above the first peeling space, and the second rotating rod 3 is located directly above the second peeling space. The mounting frame 1 is also equipped with a drive cylinder 4 for driving the first rotating rod 2 and the second rotating rod 3 to move up and down synchronously, and a drive structure for driving the first rotating rod 2 and the second rotating rod 3 to rotate synchronously. The lower end of the first rotating rod 2 is provided with a vertically extending first peeling rod 5 that is not coaxial, and the lower end of the second rotating rod 3 is provided with a vertically extending second peeling rod 6 that is not coaxial.

[0032] The lower end of the first rotating rod 2 is connected to the top end of the first peeling rod 5 via a horizontally extending first connecting rod 8, and the lower end of the second rotating rod 3 is connected to the top end of the second peeling rod 6 via a horizontally extending second connecting rod 9. The first connecting rod 8 and the second connecting rod 9 increase the rotation range of the first peeling rod 5 and the second peeling rod 6. The vertical extension of the first peeling rod 5 and the second peeling rod 6 increases the contact area with the paper tube, making it easier to peel the paper tube from the yarn bundle.

[0033] like Figure 1 As shown, the piston rod of the drive cylinder 4 is fixedly connected to the mounting bracket 1, and a mounting flange 7 is fixedly connected to the drive cylinder 4. The upper ends of the first rotating rod 2 and the second rotating rod 3 are rotatably mounted on the mounting flange 7, and the drive structure is mounted on the mounting flange 7. The mounting bracket 1 is in a fixed state. When the drive cylinder 4 is activated, the cylinder body moves up and down, thereby driving the mounting flange 7, the first rotating rod 2, the second rotating rod 3, and the drive structure to move up and down.

[0034] In this embodiment, the drive structure includes a drive motor fixed to the mounting flange 7, a drive wheel coaxially fixed to the shaft of the drive motor, a first driven wheel coaxially fixed to the first rotating rod 2, and a second driven wheel coaxially fixed to the second rotating rod 3. The drive wheel, the first driven wheel, and the second driven wheel are connected by gear / chain / belt transmission.

[0035] When the drive motor is working, it drives the driving wheel to rotate. The driving wheel drives the first driven wheel and the second driven wheel to rotate synchronously through gears / chains / belts. When the transmission is through gears, the driving wheel, the first driven wheel, and the second driven wheel are gears; when the transmission is through chains, the driving wheel, the first driven wheel, and the second driven wheel are sprockets; when the transmission is through belts, the driving wheel, the first driven wheel, and the second driven wheel are belt pulleys.

[0036] The working process of this yarn ball paper tube peeling mechanism is as follows: The mounting frame 1 descends, the first clamping structure clamps the upper side of the paper tube, and the second clamping structure clamps the other side of the upper end of the paper tube. The first driving member drives the first clamping structure to move inward, and the second driving member drives the second clamping structure to move inward, forming the first peeling space and the second peeling space. Subsequently, the first peeling rod 5 and the second peeling rod 6 extend into the first peeling space and the second peeling space respectively under the action of the driving cylinder 4. Under the action of the driving structure, the first rotating rod 2 and the second rotating rod 3 rotate, making the first peeling rod 5 and the second peeling rod 6 closer to the center line of the paper tube. In this process, the paper tube can be further separated from the yarn ball.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
