Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for textile machinery, and particularly relates to a waste yarn removing device. Background Art

[0002] During the spinning process, a large number of small tube yarns are generated in the ring spinning frame due to broken ends, failed jointing or trial spinning. This part of the small tube yarns need to remove the waste yarns and then the yarn tubes are circulated for use. In order to remove the waste yarns, the traditional method is to manually use a hook knife to hook out the waste yarns on the yarn tubes, which has low efficiency and potential safety hazards. Currently, there is a semi-automatic waste yarn removing machine on the market. It requires manual arrangement of the small tube yarns in order, and uses two semi-circular clamping blocks made of hard metal to clamp the yarn tubes at the tail of the yarn tubes, and uses a large cylinder to push the yarn tubes from the head of the yarn tubes, so that the yarn tubes are extruded from between the two clamping blocks, and the waste yarns are restricted above the two clamping blocks to achieve the separation of the tube yarns. However, the two clamping blocks of this waste yarn removing machine need to clamp the yarn tubes, which will damage or scratch the yarn tubes after clamping, and it can only remove the waste yarns on the smooth and regular-shaped aluminum ingot rods, but cannot remove the waste yarns on the steel top rods with grooves on the surface and irregular shapes completely.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solution of the present utility model will be described in detail below with reference to the drawings.

[0019] It should be noted that the small tube yarn herein includes a yarn tube, and a small amount of residual yarn is wound near the tail outside the yarn tube. The head of the small tube yarn is the small end of the yarn tube, and the tail of the small tube yarn is the large end of the yarn tube.

[0020] An embodiment of the present utility model provides a residual yarn removing device, as Figure 1 shown, including a mounting base 1, a first knife clamping assembly 2, and a second knife clamping assembly 3. A tube passing hole is provided on the mounting base 1. The first knife clamping assembly 2 and the second knife clamping assembly 3 are both installed on the same surface of the mounting base 1. The first clamping tube cavity of the first knife clamping assembly 2 and the second clamping tube cavity of the second knife clamping assembly 3 are both opposite to the tube passing hole, and the first clamping tube cavity, the second clamping tube cavity, and the tube passing hole are arranged in sequence in the horizontal direction. The clamping surfaces of the first knife clamping assembly 2 and the second knife clamping assembly 3 are arc surfaces adapted to the yarn tube of the small tube yarn.

[0021] In the waste yarn removing device of this embodiment, when removing the yarn, the small tube yarn sequentially passes through the first clamping tube cavity of the first clamping knife assembly, the second clamping tube cavity of the second clamping knife assembly, and the tube passing hole. By setting a double-layer clamping knife assembly, the first clamping knife assembly first acts on the waste yarn on the yarn tube, stirs the waste yarn, reduces or even eliminates the wrapping force of the waste yarn on the yarn tube, and the second clamping knife assembly acts on the waste yarn again to further eliminate the wrapping force of the waste yarn on the yarn tube, so that the waste yarn is separated from the yarn tube. Under the combined action of the first clamping knife assembly and the second clamping knife assembly, the waste yarn can be completely removed from the yarn tube. Whether it is an aluminum ingot rod with a smooth surface and regular shape or a steel top rod with grooves on the surface and irregular shape, the waste yarn on it can be removed cleanly. Moreover, the first clamping tube cavity, the second clamping tube cavity, and the tube passing hole are arranged in sequence in the horizontal direction. When removing the yarn, the small tube yarn passes through the first clamping tube cavity, the second clamping tube cavity, and the tube passing hole in a horizontal state in sequence. Using the horizontal yarn removing method, the tube feeding speed is fast, and the head of the yarn tube directly drops after passing through the clamping cavity formed by the two clamping knife assemblies horizontally, improving the efficiency.

[0022] Preferably, the first clamping knife assembly 2 includes a first left clamping plate 21, a first right clamping plate 22, and a first driving member 23. A first clamping tube cavity is formed between the clamping surfaces of the first left clamping plate 21 and the first right clamping plate 22. The first left clamping plate 21 is rotatably installed on the mounting base 1 through a left rotating shaft 61, and the first right clamping plate 22 is rotatably installed on the mounting base 1 through a right rotating shaft 62. The first left clamping plate 21 and the first right clamping plate 22 are engaged by gear teeth. The first driving member 23 is connected to the first left clamping plate 21 or the first right clamping plate 22. The first driving member 23 drives the first left clamping plate 21 to rotate around the left rotating shaft, thereby driving the first right clamping plate 22 to rotate around the right rotating shaft; or the first driving member 23 drives the first right clamping plate 22 to rotate around the right rotating shaft, thereby driving the first left clamping plate 21 to rotate around the left rotating shaft. The first left clamping plate 21 and the first right clamping plate 22 rotate towards each other or away from each other simultaneously. Preferably, the first driving member 23 uses a cylinder.

[0023] When the tail of the small tube yarn reaches the first clamping tube cavity of the first clamping knife assembly, the first driving member 23 drives the first left clamping plate 21 and the first right clamping plate 22 to rotate towards each other simultaneously, narrowing the first clamping tube cavity to clamp the tail of the small tube yarn. After the head of the yarn tube passes through the tube passing hole, the first driving member 23 drives the first left clamping plate 21 and the first right clamping plate 22 to rotate away from each other simultaneously, opening the first clamping tube cavity and waiting for the next small tube yarn to remove the yarn.

[0024] In this embodiment, the first clamping knife assembly uses two meshing clamping plates. Only one driving member needs to be set to drive one of the clamping plates, so that the two clamping plates can rotate towards or away from each other, thereby opening and closing the clamping tube cavity, and the structure is simple. Moreover, by driving the clamping plate to rotate around the rotating shaft, a force-increasing lever mechanism is formed, and a small cylinder can be used to make the two clamping plates form a large clamping force.

[0025] Preferably, the second clamping blade assembly 3 includes a second left clamping plate, a second right clamping plate and a second driving member. A second clamping tube cavity is formed between the clamping surfaces of the second left clamping plate and the second right clamping plate. The second left clamping plate is rotatably mounted on the mounting base 1 through a left rotating shaft 61, and the second right clamping plate is rotatably mounted on the mounting base 1 through a right rotating shaft 62. The second left clamping plate and the second right clamping plate are engaged by gear teeth. The second driving member is connected to the second left clamping plate or the second right clamping plate. The second driving member drives the second left clamping plate to rotate around the left rotating shaft, thereby driving the second right clamping plate to rotate around the right rotating shaft; or, the second driving member drives the second right clamping plate to rotate around the right rotating shaft, thereby driving the second left clamping plate to rotate around the left rotating shaft. The second left clamping plate and the second right clamping plate rotate towards each other or away from each other simultaneously. Preferably, the second driving member is a cylinder.

[0026] When the tail of the small tube yarn reaches the second clamping tube cavity of the second clamping blade assembly, the second driving member drives the second left clamping plate and the second right clamping plate to rotate towards each other simultaneously, narrowing the second clamping tube cavity to clamp the tail of the small tube yarn. When the head of the yarn tube passes through the tube-passing hole, the second driving member drives the second left clamping plate and the second right clamping plate to rotate away from each other simultaneously, opening the second clamping tube cavity and waiting for the next small tube yarn to have its yarn removed.

[0027] Preferably, the clamping surface of the first clamping blade assembly 2 is made of a hard material. The contact between the clamping surface of the first clamping blade assembly and the small tube yarn is a hard contact.

[0028] Preferably, the clamping surface of the second clamping blade assembly 3 is made of a soft material. The contact between the clamping surface of the second clamping blade assembly and the small tube yarn is a soft contact.

[0029] The small tube yarn passes through the first clamping tube cavity of the first clamping blade assembly and the second clamping tube cavity of the second clamping blade assembly in sequence. The clamping surface of the first clamping blade assembly uses hard contact. If it is an aluminum ingot rod with a smooth surface and regular shape, the first clamping blade assembly can completely eliminate the wrapping force between the residual yarn and the yarn tube. If it is a steel top rod with grooves on the surface and irregular shape, the wrapping force between the residual yarn and the yarn tube can be reduced first; while the clamping surface of the second clamping blade assembly uses soft contact to strengthen the fit with the yarn tube, and can further eliminate the wrapping force between the residual yarn and the yarn tube on the steel top rod with grooves on the surface and irregular shape that has not been completely eliminated, so that the residual yarn completely detaches from the yarn tube and is removed cleanly from the yarn tube.

[0030] Preferably, a third clamping blade assembly 4 is further mounted on the mounting base 1. The third clamping tube cavity of the third clamping blade assembly 4 is located between the first clamping tube cavity and the second clamping tube cavity. When removing the yarn, the small tube yarn passes through the first clamping tube cavity of the first clamping blade assembly, the third clamping tube cavity of the third clamping blade assembly, the second clamping tube cavity of the second clamping blade assembly and the tube-passing hole in sequence.

[0031] Preferably, the third clamping blade assembly 4 includes a third left clamping plate, a third right clamping plate and a third driving member. A third clamping tube cavity is formed between the clamping surfaces of the third left clamping plate and the third right clamping plate. The third left clamping plate is rotatably mounted on the mounting base 1 through a left rotating shaft 61, and the third right clamping plate is rotatably mounted on the mounting base 1 through a right rotating shaft 62. The third left clamping plate and the third right clamping plate are engaged by gear teeth. The third driving member is connected to the third left clamping plate or the third right clamping plate. The third driving member drives the third left clamping plate to rotate around the left rotating shaft, thereby driving the third right clamping plate to rotate around the right rotating shaft; alternatively, the third driving member drives the third right clamping plate to rotate around the right rotating shaft, thereby driving the third left clamping plate to rotate around the left rotating shaft. The third driving member drives the third left clamping plate and the third right clamping plate to rotate towards each other and away from each other simultaneously. Preferably, the third driving member is a cylinder.

[0032] When the tail of the small bobbin reaches the third clamping tube cavity of the third clamping blade assembly, the third driving member drives the third left clamping plate and the third right clamping plate to rotate towards each other simultaneously, narrowing the third clamping tube cavity to clamp the tail of the small bobbin. After the head of the bobbin passes through the tube-passing hole, the third driving member drives the third left clamping plate and the third right clamping plate to rotate away from each other simultaneously, opening the third clamping tube cavity and waiting for the next small bobbin to have its yarn removed.

[0033] Preferably, the clamping surface of the third clamping blade assembly 4 is made of a hard material. The contact between the clamping surface of the third clamping blade assembly and the small bobbin is a hard contact.

[0034] The small bobbin passes through the first clamping tube cavity of the first clamping blade assembly, the third clamping tube cavity of the third clamping blade assembly and the second clamping tube cavity of the second clamping blade assembly in sequence. The clamping surfaces of the first clamping blade assembly and the third clamping blade assembly both utilize hard contact. Under the action of the two clamping blade assemblies, the wrapping force between the residual yarn and the bobbin can be made very small or even completely eliminated. The clamping surface of the second clamping blade assembly utilizes soft contact to strengthen the fitting degree with the bobbin, and can further eliminate the wrapping force between the residual yarn and the bobbin that has not been completely eliminated. After passing through the first clamping blade assembly, the third clamping blade assembly and the second clamping blade assembly, the residual yarn can be effectively completely separated from the bobbin and removed cleanly from the bobbin.

[0035] Preferably, the mounting base 1 is further provided with a limiting base 5. The limiting base 5 is provided with a first limiting groove and a third limiting groove in the horizontal direction. The first limiting groove and the first tube clamping cavity are located in the same vertical plane, and the third limiting groove and the third tube clamping cavity are located in the same vertical plane. The end of the first knife clamping assembly is located in the first limiting groove, and the end of the third knife clamping assembly is located in the third limiting groove. The two clamping plates of the first knife clamping assembly can rotate in the first limiting groove, but cannot move in the axial direction of the small tube yarn under the restriction of the first limiting groove, so that the two clamping plates rotate stably, which is beneficial to tube clamping. The two clamping plates of the third knife clamping assembly can rotate in the third limiting groove, but cannot move in the axial direction of the small tube yarn under the restriction of the third limiting groove, so that the two clamping plates rotate stably, which is beneficial to tube clamping. Since the second knife clamping assembly is against the mounting base, and the third knife clamping assembly and the first knife clamping assembly are limited by the limiting base, the second knife clamping assembly is also limited, and the two clamping plates rotate stably and will not move back and forth, which is beneficial to tube clamping.

[0036] Preferably, the waste yarn removing device of this embodiment further includes a tube feeding driving member, which is arranged on one side close to the first clamping cavity and is used to drive the small tube yarn to move horizontally towards the first tube clamping cavity. Preferably, the tube feeding driving member adopts a cylinder, and the push rod of the cylinder is coaxial with the first tube clamping cavity, the second tube clamping cavity and the third tube clamping cavity.

[0037] The working process of the waste yarn removing device of the above preferred embodiment is as follows:

[0038] The tube feeding driving member pushes the head of the small tube yarn, so that the small tube yarn moves towards the first tube clamping cavity. When the tail of the small tube yarn reaches the first tube clamping cavity of the first knife clamping assembly, the small tube yarn stops moving, and the first knife clamping assembly reduces the first tube clamping cavity to clamp the yarn tube of the small tube yarn. After the first knife clamping assembly clamps the small tube yarn, it pushes the small tube yarn to continue moving forward. When the tail of the small tube yarn reaches the third tube clamping cavity of the third knife clamping assembly, the third knife clamping assembly clamps the yarn tube of the small tube yarn. When the tail of the small tube yarn reaches the second tube clamping cavity of the second knife clamping assembly, the second knife clamping assembly reduces the second tube clamping cavity to clamp the yarn tube of the small tube yarn. During the forward movement of the small tube yarn, the first knife clamping assembly acts on the waste yarn on the yarn tube first to reduce the wrapping force of the waste yarn on the yarn tube; the third knife clamping assembly acts on the waste yarn on the yarn tube again to further reduce or even eliminate the wrapping force of the waste yarn on the yarn tube; the second knife clamping assembly acts on the waste yarn on the yarn tube finally to completely eliminate the wrapping force of the waste yarn on the yarn tube, so that the waste yarn will not move forward with the yarn tube until the head of the yarn tube passes through the first tube clamping cavity, the third tube clamping cavity, the second tube clamping cavity and the tube passing hole in sequence, and the waste yarn is separated from the yarn tube under the combined action of the first knife clamping assembly, the third knife clamping assembly and the second knife clamping assembly.

[0039] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
