Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber production, in particular to a stripping assembly and a stripping device. Background Art

[0002] The glass fiber production process requires the raw wire to be wound on a wire winding drum and twisted to make high-quality glass fiber. After the twisting is completed, a part of the waste wire at the end of the drum will still remain on the drum, which can be removed by an automatic drum stripping machine.

[0003] The automatic drum stripping machine includes a stripping device, which includes a drum stripping clamp. When it is necessary to strip the waste wire at the drum foot, the wire winding drum is placed between the left and right drum stripping clamps. The left and right drum stripping clamps move toward each other to jointly squeeze the wire winding drum to cause it to deform, thereby reducing the winding and fixing force between the waste wire at the drum foot and the wire winding drum. Then the left and right drum stripping clamps drive the waste wire line at the drum foot on the wire winding drum to move along the axial direction of the wire winding drum, thereby separating the waste wire at the drum foot from the wire winding drum to complete the wire stripping.

[0004] However, when there are too many waste wires at the base of the winding drum, the waste wires at the base will squeeze the drum scraping fixture outward in the direction away from the winding drum, causing the drum scraping fixture to separate from the waste wires at the base, resulting in some waste wires at the base remaining on the winding drum, which need to be manually removed for a second time, affecting the next process, and further reducing the removal efficiency of the automatic drum scraping machine and the production efficiency of the glass fiber.

[0029] The utility model provides a material stripping assembly 10, please refer to Figures 1 to 6 , including two stripping clamps 11 for being arranged on opposite sides of a reel 1, the reel being used for winding a coil 2, the two stripping clamps 11 can be arranged close to each other to squeeze the reel 1 in the radial direction of the reel 1 so that the reel 1 is deformed to form an avoidance gap between it and the coil 2, each stripping clamp 11 includes a main body 111 and a hooking portion 112 that are connected to each other, the hooking portion 112 protrudes relative to the main body 111, so that when the stripping clamp 11 squeezes the reel 1, at least part of the hooking portion 112 extends into the avoidance gap to be hooked on the inner wall surface of the coil 2, so that when the stripping clamp 11 squeezes the reel 1, the coil 2 is driven to move axially along the reel 1 through the hooking portion 112 and the main body 111 when the stripping clamp 10 moves along the axial direction of the reel 1 to make the coil 2 separate from the reel 1.

[0030] The material stripping assembly 10 of the utility model includes two material stripping clamps 11, each material stripping clamp 11 includes a main body 111 and a hooking portion 112 which are connected to each other, the hooking portion 112 protruding relative to the main body 111, when the material stripping clamp 11 squeezes the reel 1, at least part of the hooking portion 112 extends into the avoidance gap to hook on the inner wall surface of the coil 2, and the hooking portion 112 hooks the coil 2 to prevent the material stripping clamp 11 from being separated from the coil 2, thereby ensuring that when the material stripping assembly 10 moves along the axial direction of the reel 1, the hooking portion 112 and the main body 111 can drive the coil 2 to move along the axial direction of the reel 1 to make the coil 2 separate from the reel 1, avoiding partial coil 2 remaining on the reel 1, and no longer needing manual secondary stripping, thereby solving the problem of reduced stripping efficiency and reduced production efficiency of glass fiber in the automatic reel stripping machine in the prior art, and improving the stripping efficiency and reduced production efficiency of glass fiber in the automatic reel stripping machine.

[0031] Specifically, Figure 4 As shown, a stopper 3 is provided at the end of the reel 1, and the stripping clamp 11 drives the coil 2 to move along the axial direction of the reel 1 in a direction away from the stopper 3 to strip the coil 2. The stopper 3 can not only stop the coil 2 to prevent the coil 2 from moving in the opposite direction, but also facilitate manual or other equipment to grasp and release the reel 1 by clamping the stopper 3, which is convenient for user operation.

[0032] In this embodiment, if Figure 1 and Figure 4 As shown, the main body 111 includes a main body extrusion part 113 and a main body connection part 114 connected to each other, the main body extrusion part 113 has a pressing edge 118 for contacting the outer wall surface of the reel 1, and the hooking part 112 is arranged at the connection between the main body connection part 114 and the main body extrusion part 113. The reel 1 is squeezed by the pressing edge 118 to deform it, so that an escape gap is formed between the reel 1 and the coil 2, thereby reducing the winding fixing force between the coil 2 and the reel 1, and facilitating the stripping fixture 11 to strip the coil 2 from the reel 1; by arranging the hooking part 112 at the connection between the main body connection part 114 and the main body extrusion part 113, at least part of the protruding hooking part 112 can smoothly extend into the escape gap and hook on the inner wall surface of the coil 2, thereby ensuring the connection reliability between the hooking part 112 and the coil 2.

[0033] In this embodiment, if Figure 1As shown, the main connecting part 114 includes a first plane 115 which is perpendicular to the moving direction of the stripping assembly 10, and the hooking part 112 includes a first end face, a second end face 116, a third end face 117 and a fourth end face which are connected to each other, the fourth end face is connected to the first plane 115, the first end face is in contact with the outer wall of the reel 1, and the third end face 117 is engaged with the inner wall of the coil 2. The fourth end face of the hooking part 112 is connected to the first plane 115, so that the hooking part 112 is connected to the main part 111; the first end face of the hooking part 112 is in contact with the outer wall of the reel 1, so that when the stripping clamp 11 squeezes the reel 1 in the radial direction of the reel 1, the contact area with the reel 1 is increased, thereby increasing the squeezing force on the reel 1, further ensuring that the reel 1 is deformed, thereby reducing the winding fixing force between the coil 2 and the reel 1, and facilitating the separation of the coil 2 from the reel 1.

[0034] In this embodiment, if Figure 1 As shown, the pressing edge 118 and the first end face together constitute the extrusion end of the stripping clamp 11, and the extrusion end is used to contact the outer wall surface of the roll 1. Specifically, the pressing edge 118 and the first end face have a smooth transition, and together constitute the extrusion end for contacting the outer wall surface of the roll 1, ensuring that the extrusion end is fully fitted with the roll 1, and further ensuring that the extrusion end can fully extrude the roll 1.

[0035] In this embodiment, if Figure 1 As shown, the line between the free end 1151 and the fixed end 1152 of the edge of the second end face 116 close to the first plane 115 is the angle line 1153, and the value range of the angle θ between the angle line 1153 and the first plane 115 is 40°≤θ≤90°. Such a setting ensures the protrusion of the hooking portion 112 relative to the first plane 115, and avoids the hooking portion 112 being too small, resulting in the hooking portion 112 being unable to hook the coil 2, resulting in the separation of the stripping fixture 11 from the coil 2.

[0036] Specifically, Figure 1 As shown, the fixed end refers to the end of the second end surface 116 close to the first plane 115 and connected to the first plane 115 , and the free end refers to the end of the second end surface 116 close to the first plane 115 and at a certain distance from the first plane 115 .

[0037] In this embodiment, if Figure 1 As shown, the angle θ between the angle line 1153 and the first plane 115 is 45°. Such a configuration further ensures the protrusion of the hooking portion 112 relative to the first plane 115, and avoids the hooking portion 112 being too small so that the hooking portion 112 cannot hook the coil 2, resulting in the separation of the stripping fixture 11 from the coil 2.

[0038] In this embodiment, if Figure 1As shown, the distance d between the free end of the edge of the second end surface 116 close to the first plane 115 and the first plane 115 is 1 cm. Such a setting further ensures the protrusion of the hooking portion 112 relative to the first plane 115, and avoids the hooking portion 112 being too small so that the hooking portion 112 cannot hook the coil 2, resulting in the separation of the stripping fixture 11 from the coil 2.

[0039] In this embodiment, if Figure 1 As shown, the fourth end surface of the hooking portion 112 is welded to the first plane 115 of the main body connecting portion 114. Such a configuration ensures the connection reliability between the hooking portion 112 and the main body 111, and avoids the hooking portion 112 from being separated from the main body 111, resulting in the hooking portion 112 being unable to hook the coil 2 smoothly, resulting in the separation of the stripping fixture 11 from the coil 2.

[0040] In this embodiment, if Figure 1 As shown, the hooking portion 112 is integrally injection molded with the main body 111. Such a configuration further ensures the connection reliability between the hooking portion 112 and the main body 111, and prevents the hooking portion 112 from being separated from the main body 111, resulting in the hooking portion 112 being unable to smoothly hook the coil 2, resulting in the separation of the stripping fixture 11 from the coil 2; and at the same time, it reduces the production difficulty and production cost of the stripping fixture 11.

[0041] The utility model also provides a stripping device, such as Figures 2 to 6 As shown, it includes a plurality of the scraping assemblies 10 in the above-mentioned embodiments, and the plurality of scraping assemblies 10 are arranged at intervals along a direction perpendicular to the axial direction of the reel 1; the scraping assemblies 10 also include two transmission rods 18 and a driving member 19, and the two transmission rods 18 are arranged one-to-one correspondingly to the two scraping clamps 11, and the main body 111 of the scraping clamp 11 is provided with a penetration hole 1111, and the transmission rod 18 is penetrated into the penetration hole 1111 to make the main body 111 and the transmission rod 18 transmission connected; the driving member 19 is drivingly connected to the transmission rod 18, so that when the driving member 19 moves along the axial direction of the reel 1 toward the direction close to the scraping clamp 11, the two transmission rods 18 are driven to drive the two scraping clamps 11 to move toward each other.

[0042] Specifically, the stripping assembly 10 further includes a dovetail movable device 150, which includes two movable segments 151 hinged to each other, the first ends of the two movable segments 151 are hinged to each other and connected to the driving member 19, and the other ends of the two movable segments 151 are respectively connected to two transmission rods 18. When the driving member 19 moves along the axial direction of the reel 1 toward the direction close to the stripping fixture 11, the two movable segments 151 are driven to move closer to each other, and the two movable segments 151 drive the two transmission rods 18 to move toward each other, and the two transmission rods 18 drive the two stripping fixtures 11 to move closer to each other to squeeze the reel 1 along the radial direction of the reel 1, so that the reel 1 is deformed to form an avoidance gap with the coil 2. Among them, the stripping fixture 11 is fixed to the transmission rod 18 by bolts, which is convenient for later replacement.
