Description

Technical Field

[0001] This utility model belongs to the field of glass fiber processing technology and relates to a paper tube receiving and peeling mechanism for glass fiber yarn bundles. 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 the inward movement distance of the upper end of the paper tube being less than the radius of the paper tube. The peeling space formed between the paper tube and the yarn ball is small, which is not conducive to the subsequent peeling action of the insertion rod and cannot guarantee that the paper tube is completely peeled 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 paper tube retraction and peeling mechanism that enables complete peeling.

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

[0006] A paper tube inward and 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 bundle to form a first peeling space. The mounting frame is provided with a first peeling structure located above the first peeling space. The second driving member and the second clamping structure enable the paper tube and the yarn bundle to form a second peeling space. The mounting frame is also provided with a second peeling structure located above the second peeling space.

[0007] Vibration motors are provided on the first and second driving components.

[0008] The first and second driving components can be pneumatic or electric. The descent height of the first and second peeling structures can be set according to the different yarn bundle conditions to form different degrees of peeling.

[0009] The working process of the paper tube receiving and peeling mechanism is as follows:

[0010] The mounting frame descends, the first clamping structure clamps the upper end of the paper tube, and the first driving component drives the first clamping structure to move inward, forming a first peeling space between the upper end of the paper tube and the yarn bundle. The first peeling structure moves downward and inserts into the first peeling space. The vibration motor drives the first peeling structure to vibrate, causing the paper tube to separate from the yarn bundle at that point. Subsequently, the first driving component drives the first clamping structure to retract, providing clearance for the movement of the second clamping structure. Then, the second clamping structure clamps the upper end of the paper tube, and the second driving component drives the second clamping structure to move inward, forming a second peeling space between the upper end of the paper tube and the yarn bundle. The second peeling structure moves downward and inserts into the second peeling space. The vibration motor drives the second peeling structure to vibrate, causing the paper tube to separate from the yarn bundle at that point. Subsequently, the second driving component drives the second clamping structure to retract to a position opposite to the first clamping mechanism. Finally, the mounting frame rises under the action of an external power component (such as a cylinder), pulling the paper tube out of the yarn bundle.

[0011] In the above-mentioned paper tube receiving and 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.

[0012] The first cylinder and the second cylinder are arranged opposite each other, and their piston rods can extend inward and downward in stages along the radial direction of the paper tube, thereby driving the first clamping structure and the second clamping structure to move closer to each other, causing the two opposite sides of the upper end of the paper tube to tilt inward and downward.

[0013] In the aforementioned paper tube receiving and 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 tube. The size of this angle depends on the diameter of the paper tube; the larger the diameter, the larger the angle.

[0014] In the aforementioned paper tube receiving and peeling mechanism, the first clamping structure is a first finger, which has a first gripper and a second gripper. The first gripper and the second gripper work together to clamp the upper side of the paper tube. The first gripper and the second gripper can be pneumatic or electric.

[0015] In the above-mentioned paper tube receiving and peeling mechanism, the lower end of the first gripper has a first connecting portion extending toward the side of the second clamping structure, and the end of the first connecting portion away from the first gripper has a first clamping portion extending vertically downward. The lower end of the second gripper has a second connecting portion extending toward the side of the second clamping structure, and the end of the second connecting portion away from the second gripper has a second clamping portion extending vertically downward. The first clamping portion and the second clamping portion work together to clamp the upper side of the paper tube.

[0016] In the aforementioned paper tube retraction and peeling mechanism, the length of the first clamping part is greater than half the depth of the paper tube. The first clamping part can cooperate with the second clamping part to clamp the upper side of the paper tube. When the insert rod moves downward, it can support the inner wall of the paper tube. After the paper tube is pulled out of the yarn bundle, it can also be reset outward under the action of the first cylinder, and also provide support for the paper tube.

[0017] In the aforementioned paper tube receiving and peeling mechanism, the second clamping structure is a second finger, which has a third and a fourth gripper. The third and fourth grippers work together to clamp the upper side of the paper tube. The third and fourth grippers can be pneumatic or electric.

[0018] In the above-mentioned paper tube receiving and peeling mechanism, the lower end of the third gripper has a third connecting portion extending toward the first clamping structure, and the end of the third connecting portion away from the third gripper has a third clamping portion extending vertically downward. The lower end of the fourth gripper has a fourth connecting portion extending toward the first clamping structure, and the end of the fourth connecting portion away from the fourth gripper has a fourth clamping portion extending vertically downward. The third clamping portion and the fourth clamping portion work together to clamp the upper side of the paper tube.

[0019] In the aforementioned paper tube receiving and peeling mechanism, the length of the third clamping part is greater than half the depth of the paper tube. The third clamping part can cooperate with the fourth clamping part to clamp the upper side of the paper tube, support the inner wall of the paper tube during the clamping process, and after the paper tube is pulled out of the yarn ball, it can also be reset outward under the action of the second cylinder, and provide support for the paper tube.

[0020] In the aforementioned paper tube receiving and peeling mechanism, the first peeling structure includes at least one first insert rod that slides vertically through the mounting frame and a first drive cylinder / electric cylinder on the mounting frame for driving the first insert rod to move up and down, with the first insert rod located directly above the first peeling space; the second peeling structure includes at least one second insert rod that slides vertically through the mounting frame and a second drive cylinder / electric cylinder on the mounting frame for driving the second insert rod to move up and down, with the second insert rod located directly above the second peeling space.

[0021] Specifically, there are two first insertion rods, both controlled simultaneously by a first drive cylinder / electric cylinder. When the piston rod of the first drive cylinder / electric cylinder extends or retracts, it drives the two first insertion rods to move up and down synchronously. The two first insertion rods are located on either side of the first finger. Similarly, there are two second insertion rods, both controlled simultaneously by a second drive cylinder / electric cylinder. When the piston rod of the second drive cylinder / electric cylinder extends or retracts, it drives the two second insertion rods to move up and down synchronously. The two second insertion rods are located on either side of the second finger. The first and second drive cylinders / electric cylinders operate asynchronously.

[0022] Compared with existing technologies, this paper tube receiving and peeling mechanism has the following advantages:

[0023] Since the first and second driving components do not operate synchronously, when the first driving component operates, the second driving component remains stationary, providing clearance for the first clamping structure. This allows the upper end of the paper tube to move inward a distance greater than the radius of the paper tube, resulting in a larger first peeling space. This allows the first peeling mechanism to be positioned closer to the center of the paper tube, which is more conducive to peeling the paper tube. When the second driving component operates, the first driving component has already retracted, providing clearance for the second clamping structure. This allows the upper end of the paper tube to move inward a distance greater than the radius of the paper tube, resulting in a larger second peeling space. This allows the second peeling mechanism to be positioned closer to the center of the paper tube, which is more conducive to peeling the paper tube. The inward and downward movement direction of the first and second clamping structures is the same as the inward tilting direction of the upper end of the paper tube. The upper side of the paper tube is less likely to detach from the first / second clamping structure, improving the inward retraction effect. Furthermore, it prevents debris on the paper tube from entering the gap between the first / second clamping structure and the paper tube when there is relative sliding between the first / second clamping structure and the paper tube, thus avoiding a decrease in clamping force.

Detailed Implementation

[0027] 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.

[0028] like Figure 1 The paper tube inward and peeling mechanism shown includes a mounting frame 1, 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 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. The first driving member and the first clamping structure enable the paper tube and the yarn bundle to form a first peeling space. The mounting frame 1 is provided with a first peeling structure located above the first peeling space. The second driving member and the second clamping structure enable the paper tube and the yarn bundle to form a second peeling space. The mounting frame 1 is also provided with a second peeling structure located above the second peeling space.

[0029] Vibration motors are installed on the first and second driving components. The descent height of the first and second peeling structures is set according to the different yarn bundle conditions to form different degrees of peeling.

[0030] like Figure 1 and Figure 2 As shown, the first driving component is a first cylinder 41 mounted on the mounting frame 1. The first cylinder 41 extends radially inward and downward along the paper tube. A first mounting seat 42 is provided on the piston rod of the first cylinder 41, and a first clamping structure is provided on the first mounting seat 42. The second driving component is a second cylinder 51 mounted on the mounting frame 1. The second cylinder 51 extends radially inward and downward along the paper tube. A second mounting seat 52 is provided on the piston rod of the second cylinder 51, and a second clamping structure is provided on the second mounting seat 52. The first cylinder 41 and the second cylinder 51 are arranged opposite to each other, and their piston rods can extend radially inward and downward along the paper tube in stages, thereby driving the first clamping structure and the second clamping structure to move closer to each other, causing the two opposite sides of the upper end of the paper tube to tilt inward and downward.

[0031] Specifically, the piston rod of the first cylinder 41 makes an angle of 5° to 30° with the horizontal plane, and the piston rod of the second cylinder 51 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 41 and the second cylinder 51 both form a 25° angle with the horizontal plane, which is beneficial for tilting the upper side of the paper tube inward and downward.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the first clamping structure is a first finger 6, which has a first gripper 61 and a second gripper 62. The first gripper 61 and the second gripper 62 work together to clamp the upper side of the paper tube. The first gripper 61 and the second gripper 62 can be pneumatic or electric.

[0033] like Figure 2 As shown, the lower end of the first gripper 61 has a first connecting portion 63 extending toward the second clamping structure. The end of the first connecting portion 63 away from the first gripper 61 has a first clamping portion 64 extending vertically downward. The lower end of the second gripper 62 has a second connecting portion 65 extending toward the second clamping structure. The end of the second connecting portion 65 away from the second gripper 62 has a second clamping portion 66 extending vertically downward. The first clamping portion 64 and the second clamping portion 66 work together to clamp the upper side of the paper tube.

[0034] The length of the first clamping part 64 is greater than half the depth of the paper tube. The first clamping part 64 can cooperate with the second clamping part 66 to clamp the upper side of the paper tube. When the insert rod moves downward, it can support the inner wall of the paper tube. After the paper tube is pulled out of the yarn ball, it can also be reset outward under the action of the first cylinder 41, and also provide support for the paper tube.

[0035] In this embodiment, as Figure 1 and Figure 2 As shown, the second clamping structure is a second finger 7, which has a third claw 71 and a fourth claw 72. The third claw 71 and the fourth claw 72 work together to clamp the upper side of the paper tube.

[0036] The third gripper 71 and the fourth gripper 72 can be pneumatic or electric.

[0037] like Figure 2As shown, the lower end of the third gripper 71 has a third connecting portion 73 extending toward the first clamping structure. The end of the third connecting portion 73 away from the third gripper 71 has a third clamping portion 74 extending vertically downward. The lower end of the fourth gripper 72 has a fourth connecting portion 74 extending toward the first clamping structure. The end of the fourth connecting portion 74 away from the fourth gripper 72 has a fourth clamping portion 76 extending vertically downward. The third clamping portion 74 and the fourth clamping portion 76 work together to clamp the upper side of the paper tube.

[0038] The length of the third clamping part 74 is greater than half the depth of the paper tube. The third clamping part 74 can cooperate with the fourth clamping part 76 to clamp the upper side of the paper tube. During the clamping process, it supports the inner wall of the paper tube. After the paper tube is pulled out of the yarn ball, it can also be reset outward under the action of the second cylinder 51 and provide support for the paper tube.

[0039] like Figure 1 As shown, the first peeling structure includes two first insert rods 21 that slide vertically through the mounting frame 1 and a first drive cylinder 22 on the mounting frame 1 for driving the first insert rods 21 to move up and down. The first insert rods 21 are located directly above the first peeling space. The second peeling structure includes two second insert rods 31 that slide vertically through the mounting frame 1 and a second drive cylinder 32 on the mounting frame 1 for driving the second insert rods 31 to move up and down. The second insert rods 31 are located directly above the second peeling space.

[0040] Specifically, the two first insertion rods 21 are simultaneously controlled by the first drive cylinder 22. When the piston rod of the first drive cylinder 22 extends or retracts, it can drive the two first insertion rods 21 to move up and down synchronously. The two first insertion rods 21 are located on both sides of the first finger 6. The two second insertion rods 31 are simultaneously controlled by the second drive cylinder 32. When the piston rod of the second drive cylinder 32 extends or retracts, it can drive the two second insertion rods 31 to move up and down synchronously. The two second insertion rods 31 are located on both sides of the second finger 7. The first drive cylinder 22 and the second drive cylinder 32 operate asynchronously.

[0041] The working process of the paper tube receiving and peeling mechanism is as follows:

[0042] Mounting frame 1 descends, the first clamping structure clamps the upper end of the paper tube, the first driving member drives the first clamping structure to move inward, so that the upper end of the paper tube and the yarn bundle form a first peeling space. The first peeling structure moves downward and inserts into the first peeling space. The vibration motor drives the first peeling structure to vibrate, so that the paper tube and the yarn bundle are separated at this point. Then the first driving member drives the first clamping structure to retract, providing clearance for the movement of the second clamping structure. Then the second clamping structure clamps the upper end of the paper tube, the second driving member drives the second clamping structure to move inward, so that the upper end of the paper tube and the yarn bundle form a second peeling space. The vibration motor drives the second peeling structure to vibrate, the second peeling structure moves downward and inserts into the second peeling space, so that the paper tube and the yarn bundle are separated at this point. Then the second driving member drives the second clamping structure to retract to a position opposite to the first clamping mechanism. Finally, mounting frame 1 rises under the action of an external power component (such as a cylinder), pulling the paper tube out of the yarn bundle.

[0043] To facilitate the installation of the first cylinder 41 and the second cylinder 51, a first connecting rib 81 and a second connecting rib 82 forming a triangle are respectively provided on two opposite sides of the mounting bracket 1. The first cylinder 41 is mounted on the bottom edge of the first connecting rib 81, and the second cylinder 51 is mounted on the bottom edge of the second connecting rib 82.
