Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass fiber processing technology and relates to a yarn winding and peeling mechanism. Background Technology
[0002] Chinese patent discloses a paper tube and yarn extraction device [application publication number CN115806224A]. A yarn-gathering cylinder drives a yarn-gathering arm to move, pushing the yarn between the paper tube and the yarn roll to between two winding rods. A third motor drives a template to rotate, causing the yarn to wind around the winding rods. After a specified winding time, a shearing cylinder drives a pneumatic shear to extend and cut the yarn. A rotating cylinder rotates 90 degrees, so that the winding rod is facing the stripping rod. A stripping cylinder drives the stripping rod to move, and a lifting cylinder drives the stripping rod to descend. At the same time, a bidirectional clamping cylinder retracts, causing the two winding rods to move closer to each other. The stripping cylinder drives the stripping rod to move, and the stripping rod strips the yarn to the waste bin.
[0003] Because there is no structure to clamp the yarn, the yarn is in a loose state when it enters between the two winding rods. When the template rotates and drives the two winding rods to rotate, the yarn is very easy to detach from the winding rods, which fails to achieve the purpose of winding the yarn. Moreover, the wound yarn is relatively loose, which can easily lead to equipment failure. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a yarn winding and unwinding mechanism with good winding effect.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A yarn winding and unwinding mechanism includes a frame, a first slide block slidably mounted on the frame along the X direction, a second slide block slidably mounted on the first slide block along the Y direction, and a third slide block slidably mounted on the frame along the Y direction. The second slide block has a winding structure, and the third slide block has a unwinding structure. The winding mechanism includes a winding seat driven to rotate by a winding motor and two winding rods oppositely mounted on the winding seat. An anti-detachment rod is provided between the two winding rods. The anti-detachment rod, in conjunction with one of the winding rods, prevents yarn entering between the two winding rods from detaching. When yarn enters between the two winding rods, the anti-detachment rod activates and cooperates with one of the winding rods to prevent the yarn from detaching.
[0007] In the above-mentioned yarn winding and stripping mechanism, one winding rod is coaxially fixed to the shaft of the winding motor, the winding seat is fixed to the winding rod, the other winding rod is oscillating / sliding inside the winding seat and driven by the first power member, and the anti-detachment rod is oscillating / sliding inside the winding seat and driven by the second power member.
[0008] Before the yarn enters between the two winding rods, the anti-detachment rod is positioned close to one of the winding rods, creating an opening between the anti-detachment rod and the other winding rod for the yarn to enter. Once the yarn enters, the second drive unit drives the anti-detachment rod to swing / slide, cooperating with the other winding rod to clamp / limit the yarn, preventing it from coming loose. During yarn winding, the two winding rods are parallel to each other. When the stripping structure strips the yarn, the distance between the two winding rods decreases under the action of the first power unit, and the anti-detachment rod returns to its original position under the action of the second power unit, facilitating the yarn's release from between the two winding rods.
[0009] In the aforementioned yarn winding and unwinding mechanism, a yarn guide plate is coaxially fixed to the winding rod, which is coaxially connected to the shaft of the winding motor. The yarn guide plate has a clearance opening for another winding rod and / or an anti-derailment rod to pass through. The yarn guide plate can limit the yarn and prevent it from winding onto the winding seat or the winding motor.
[0010] In the above-mentioned yarn winding and stripping mechanism, the anti-detachment rod is coaxially fixed to the rotating shaft of the rotary motor, a third power component is fixed on the anti-detachment rod, the winding seat is located on the telescopic end of the third power component and sleeved outside the third power component, and one of the winding rods is oscillating / sliding inside the winding seat and driven by a fourth power component.
[0011] Before the yarn enters between the two winding rods, a third power component drives the winding seat to move as a whole, causing one winding rod to press against the anti-detachment rod, creating an opening between the other winding rod and the anti-detachment rod for the yarn to enter. After the yarn enters, the third power component drives the winding seat to move in the opposite direction, causing the other winding rod to press against the anti-detachment rod, thus clamping the yarn. Subsequently, a rotary motor drives the anti-detachment rod to rotate, thereby causing the winding seat and the two winding rods to rotate, winding the yarn onto the two winding rods. When the stripping structure strips the yarn, the fourth power component reduces the distance between the two winding rods, and the third power component drives the winding seat to move, centering the anti-detachment rod between the two winding rods. The yarn is no longer restricted, which facilitates the yarn's release from between the two winding rods and makes the wound yarn tighter.
[0012] In the above-mentioned yarn winding and stripping mechanism, the anti-detachment rod is cylindrical, and the winding rod has a relief groove on the side near the anti-detachment rod that cooperates with the anti-detachment rod. When the winding rod approaches the anti-detachment rod, the anti-detachment rod is located in the relief groove.
[0013] In the above-mentioned yarn winding and stripping mechanism, the side of the winding rod away from the anti-detachment rod is parallel to the side of the winding rod close to the anti-detachment rod.
[0014] In the above-mentioned yarn winding and stripping mechanism, the stripping structure includes a fifth driving member disposed on a third slide and a stripping rod driven by the fifth driving member to move in the Z direction. The stripping rod has an X-direction extension section and a Z-direction extension section, and the Z-direction extension section is located at one end of the X-direction extension section near the winding structure.
[0015] In the above-mentioned yarn winding and stripping mechanism, the first slide is driven by the first cylinder, the second slide is driven by the second cylinder, and the third slide is driven by the third cylinder.
[0016] Compared with existing technologies, this yarn winding and unwinding mechanism has the following advantages:
[0017] Because of the anti-detachment rod, when the yarn enters between the two winding rods, the anti-detachment rod, under the action of the second power component, cooperates with one of the winding rods to prevent the yarn from coming off, resulting in good yarn winding effect and reduced equipment failure rate; when the stripping structure strips the yarn, the distance between the two winding rods is reduced under the action of the first power component, and the anti-detachment rod returns to its original position under the action of the second power component, which is conducive to the yarn coming off between the two winding rods.

Detailed Implementation
[0022] 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.
[0023] Example 1
[0024] like Figure 1 The yarn winding and stripping mechanism shown includes an L-shaped frame 1, a portion of which extends along the X direction and the other portion extends along the Y direction.
[0025] like Figure 1As shown, two guide rails extending in the X direction are provided on the part of the frame 1 extending in the X direction. A first slide block 2 is slidably provided on the guide rails. A first cylinder 13 extending in the X direction is fixedly connected to the frame 1. The piston rod of the first cylinder 13 is fixedly connected to the first slide block 2.
[0026] like Figure 1 As shown, two guide rails extending along the Y direction are provided on the slide block, and a second slide block 3 is slidably provided on the guide rails. A second cylinder 14 extending along the Y direction is provided on the first slide block 2. The piston rod of the second cylinder 14 is fixedly connected to the second slide block 3. A mounting post 16 extending along the Z direction is fixedly connected to the second slide block 3, and a winding structure is installed on the mounting post 16.
[0027] like Figure 1 As shown, a third cylinder 15 that moves in the Y direction is provided on the portion of the frame 1 that extends in the Y direction. The third cylinder 15 is provided with a third slide block 4 that is driven by the third cylinder 15. A peeling structure is provided on the third slide block 4.
[0028] In this embodiment, as Figure 1 As shown, the peeling structure includes a fifth driving member 10 extending in the Z direction and mounted on the third slide 4, and a peeling rod driven by the fifth driving member 10 to move in the Z direction. In this embodiment, the fifth driving member 10 is a cylinder, and the peeling rod is fixed to the piston rod of the cylinder. The peeling rod has an X-direction extending section 11 and a Z-direction extending section 12, with the Z-direction extending section 12 located at one end of the X-direction extending section 11 near the winding structure.
[0029] like Figure 2 As shown, the winding mechanism includes a winding base 5 driven to rotate by a rotary motor and two winding rods 6 opposite to each other on the winding base 5. The rotary motor is mounted on a mounting post 16 and extends along the Y direction. An anti-detachment rod 7 is provided between the two winding rods 6. The anti-detachment rod 7, in conjunction with one of the winding rods 6, prevents the yarn entering between the two winding rods 6 from coming out. In the initial state, both winding rods 6 and the anti-detachment rod 7 extend along the Y direction. When the yarn enters between the two winding rods 6, the anti-detachment rod 7 activates and cooperates with one of the winding rods 6 to prevent the yarn from coming out, and makes the wound yarn tighter, reducing the subsequent failure rate of the equipment.
[0030] like Figure 2 As shown, one of the winding rods 6 is coaxially fixed to the shaft of the rotary motor, and the winding seat 5 is fixed to the winding rod 6. In this embodiment, the other winding rod 6 is slidably disposed in the winding seat 5 and driven by the first power member. The first power member is a cylinder extending in the X direction. When the cylinder is activated, it can drive the sliding winding rod 6 to move closer to or away from the fixed winding rod 6, thereby adjusting the distance between the two winding rods 6 to facilitate the yarn falling off during peeling.
[0031] In other embodiments, another winding rod 6 is hinged within the winding seat 5 and is driven to swing by a first power member. Specifically, the first power member is a cylinder, the piston rod of which rests on the swingable winding rod 6 and is equipped with a return spring. When the piston rod of the cylinder retracts, the spring can reset the swingable winding rod 6.
[0032] like Figure 1 As shown, the anti-detachment rod 7 is hinged in the winding seat 5 and is driven to swing by a second power component, which is a cylinder. The piston rod of the cylinder rests on the anti-detachment rod 7 and is equipped with a return spring. When the piston rod of the cylinder is retracted, the anti-detachment rod 7 can be reset by the spring.
[0033] In other embodiments, the anti-detachment rod 7 may also be slidably disposed within the winding seat 5.
[0034] like Figure 2 As shown, a wire stop plate 8 is coaxially fixed to the winding rod 6, which is coaxially fixed to the shaft of the rotary motor. The wire stop plate 8 is provided with a clearance opening 9 for another winding rod 6 and / or an anti-derailment rod 7 to pass through. The clearance opening 9 provides clearance space for the swinging / sliding of the other winding rod 6 and / or the anti-derailment rod 7. The wire stop plate 8 can limit the yarn and prevent the yarn from winding outside the set range.
[0035] During operation, the first cylinder 13 and the second cylinder 14 drive the second slide block 3 to move, causing the winding structure to move above the yarn bundle on the conveyor line. During this process, the yarn enters the opening formed between the anti-loosening rod 7 and the winding rod 6. Subsequently, the second drive unit drives the anti-loosening rod 7 to swing / slide, cooperating with the other winding rod 6 to clamp / limit the yarn and prevent it from coming loose. Then, the rotary motor drives the winding block 5 to rotate, winding the yarn onto the two winding rods 6. After winding for a period of time, the rotary motor stops, and when the two winding rods 6 are on the same horizontal plane, the third cylinder 15 drives the peeling rod to move downward, causing the peeling rod to insert into the wound yarn.
[0036] Subsequently, under the action of the first power component, the distance between the two winding rods 6 is reduced, and the anti-detachment rod 7 returns to its original position under the action of the second power component. Finally, the third cylinder 15 causes the peeling rod to move away from the second slide block 3, so that the yarn is detached from the two winding rods 6.
[0037] Example 2
[0038] The structural principle of this embodiment is basically the same as that of Embodiment 1, the difference being the winding structure. For example... Figure 3As shown, the anti-detachment rod 7 is coaxially fixed to the rotating shaft of the rotary motor. A third power component is fixed on the anti-detachment rod 7. In this embodiment, the third power component is a cylinder extending in the X direction. The winding seat 5 is located on the telescopic end of the third power component and sleeved outside the third power component. When the piston rod of the cylinder extends or retracts, it can drive the winding seat 5 to move in the X direction, thereby controlling the distance between the winding rod 6 and the anti-detachment rod 7. One of the winding rods 6 is slidably disposed within the winding seat 5 and is driven by a fourth power component. In this embodiment, the fourth driving component is a cylinder extending in the X direction. When the piston rod of the fourth driving component extends or retracts, it can drive the winding rod 6 to move in the X direction. In order to guide the winding rod 6, such as... Figure 3 As shown, a guide rod extending in the X direction is provided inside the winding seat 5.
[0039] In other embodiments, one of the winding rods 6 is hinged to the winding seat 5 and is oscillating and resetting by a cylinder and a spring.
[0040] like Figure 3 As shown, the anti-detachment rod 7 is cylindrical, and the winding rod 6 has a relief groove on the side near the anti-detachment rod 7 that cooperates with the anti-detachment rod 7. When the winding rod 6 approaches the anti-detachment rod 7, the anti-detachment rod 7 is located in the relief groove. The side of the winding rod 6 away from the anti-detachment rod 7 is parallel to the side of the winding rod 6 near the anti-detachment rod 7.
[0041] Before the yarn enters between the two winding rods 6, the third power component drives the winding seat 5 to move as a whole, so that one of the winding rods 6 is pressed against the anti-detachment rod 7, forming an opening between the other winding rod 6 and the anti-detachment rod 7 for the yarn to enter. After the yarn enters, the third power component drives the winding seat 5 to move in the opposite direction, so that the other winding rod 6 is pressed against the anti-detachment rod 7 to clamp the yarn. Then, the rotary motor drives the anti-detachment rod 7 to rotate, thereby driving the winding seat 5 and the two winding rods 6 to rotate, winding the yarn onto the two winding rods 6. When the stripping structure strips the yarn, the distance between the two winding rods 6 is reduced under the action of the fourth power component, and the movement of the winding seat 5 driven by the third power component makes the anti-detachment rod 7 centrally located between the two winding rods 6, so that the yarn is no longer restricted, which is conducive to the stripping of the yarn.

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.
