Description

Technical Field

[0001] This utility model relates to the field of PET fiber production and processing technology, and in particular to a PET fiber feeding device. Background Technology

[0002] PET fiber, as an important synthetic fiber, is widely used in textiles, clothing, industrial fabrics and composite materials. In the production and processing of PET fiber, the unwinding process is one of the key steps. Existing PET fiber unwinding mechanisms generally use a round rod with a bent outer end to prevent the spool from falling off. This bent part cannot be too long to ensure that the spool can fit onto the round rod. Because the length of the spool may vary, shorter spools may sway from side to side during unwinding. Sometimes, the swaying amplitude may even be too large, causing the spool to fall off.

[0003] To address the aforementioned issues, existing patent (CN220316926U) discloses a PET fiber unwinding mechanism that facilitates positioning. A rotatable adjusting rod ensures smooth winding without affecting the upper and lower windings. A U-shaped pin positions the adjusting rod, and a limiting block further restricts the winding, preventing lateral swaying and significantly improving stability during unwinding.

[0004] However, in the aforementioned prior art, the U-shaped pin needs to be controlled to replace the coil, resulting in low efficiency in replacing the coil. Utility Model Content

[0005] The purpose of this invention is to provide a PET fiber feeding device, which aims to solve the technical problem in the prior art that the U-shaped pin needs to be controlled to replace the spool, resulting in low efficiency in replacing the spool.

[0006] To achieve the above objectives, this utility model employs a PET fiber feeding device, comprising a mounting plate, a feeding rod, and a replacement assembly. The feeding rod is fixedly connected to the mounting plate and is located on one side of the mounting plate.

[0007] The replacement component includes a limiting ring, a first limiting block, a second limiting block, a clamping component, and a moving component. The limiting ring is detachably connected to the pay-off rod and wraps around the pay-off rod. The first limiting block is located on one side of the pay-off rod, and the inner side of the first limiting block is in contact with the surface of the pay-off rod. The second limiting block is located on one side of the pay-off rod, and the inner side of the second limiting block is in contact with the surface of the pay-off rod. The clamping component is located above the first limiting block, and the moving component is located above the pay-off rod.

[0008] The clamping component includes a fixed shell, a threaded rod, and a connecting unit. The fixed shell is slidably connected to the first limiting block and is located above the first limiting block. The fixed shell is also slidably connected to the second limiting block. The threaded rod is threadedly connected to the first limiting block and passes through both the first and second limiting blocks. The threads at both ends of the threaded rod have opposite directions. The connecting unit is located above the fixed shell.

[0009] The connecting unit includes a first connecting block and a second connecting block. The first connecting block is fixedly connected to the fixed shell and is located above the fixed shell. The second connecting block is fixedly connected to the fixed shell and is located above the fixed shell.

[0010] The movable component includes a first movable slot, a second movable slot, a movable block, and a drive unit. The movable block is detachably connected to the first connecting block and is located above the first connecting block. The movable block is also detachably connected to the second connecting block. The first movable slot is fixedly connected to the mounting plate and is located on one side of the mounting plate. The first movable slot is slidably connected to the movable block. The second movable slot is fixedly connected to the mounting plate and is located on one side of the mounting plate. The second movable slot is slidably connected to the movable block. The drive unit is located above the fixed housing.

[0011] The drive unit includes a drive rod, a gear, and a rack. The drive rod is rotatably connected to the moving block and passes through the moving block. The gear is detachably connected to the drive rod and is located above the drive rod. The rack is detachably connected to the second moving slot and is located above the second moving slot. The gear meshes with the rack.

[0012] This utility model discloses a PET fiber feeding device. When it is necessary to replace the spool, the clamping motor can be started to drive the threaded rod to rotate. The rotation of the threaded rod can drive the first limiting block and the second limiting block to move simultaneously, thereby removing the limitation on the spool on the feeding rod and making it convenient to remove the spool for replacement. After replacement, the clamping motor can be controlled to drive the threaded rod to rotate, causing the first limiting block and the second limiting block to move towards each other, so that their inner sides are in contact with the surface of the feeding rod, thereby cooperating with the limiting ring to limit the movement.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1-4 ,in Figure 1 This is a schematic diagram of the PET fiber feeding device of this utility model. Figure 2 This is a front view of the PET fiber feeding device of this utility model. Figure 3 This is a top view of the PET fiber feeding device of this utility model. Figure 4 This is the utility model Figure 2 A cross-sectional view of the AA line structure.

[0021] This utility model provides a PET fiber feeding device, including a mounting plate 101, a feeding rod 102 and a replacement component. The feeding rod 102 is fixedly connected to the mounting plate 101 and is located on one side of the mounting plate 101.

[0022] The replacement component includes a limiting ring 103, a first limiting block 104, a second limiting block 105, a clamping component, and a moving component. The limiting ring 103 is detachably connected to the wire feeding rod 102 and wraps around the wire feeding rod 102. The first limiting block 104 is located on one side of the wire feeding rod 102, and the inner side of the first limiting block 104 is in contact with the surface of the wire feeding rod 102. The second limiting block 105 is located on one side of the wire feeding rod 102, and the inner side of the second limiting block 105 is in contact with the surface of the wire feeding rod 102. The clamping component is located above the first limiting block 104, and the moving component is located above the wire feeding rod 102.

[0023] In this embodiment, when the wire spool needs to be replaced, the clamping motor 116 is started to drive the threaded rod 107 to rotate. The rotation of the threaded rod 107 can drive the first limiting block 104 and the second limiting block 105 to move in opposite directions at the same time, thereby canceling the restriction on the wire spool on the wire feeding rod 102, so as to facilitate the removal of the wire spool for replacement. After the replacement is completed, the clamping motor 116 is controlled to drive the threaded rod 107 to rotate in the opposite direction, which drives the first limiting block 104 and the second limiting block 105 to move towards each other, so that their inner sides are in contact with the surface of the wire feeding rod 102, thereby cooperating with the limiting ring 103 to limit the wire.

[0024] Furthermore, the clamping component includes a fixed shell 106, a threaded rod 107, and a connecting unit. The fixed shell 106 is slidably connected to the first limiting block 104 and is located above the first limiting block 104. The fixed shell 106 is also slidably connected to the second limiting block 105. The threaded rod 107 is threadedly connected to the first limiting block 104 and passes through both the first limiting block 104 and the second limiting block 105. The threads at both ends of the threaded rod 107 have opposite directions. The connecting unit is located above the fixed shell 106.

[0025] In this embodiment, the clamping motor 116 is started to drive the threaded rod 107 to rotate. By utilizing the reverse threads at both ends of the threaded rod 107, the first limiting block 104 and the second limiting block 105 can move in opposite directions at the same time, thereby loosening or clamping the wire coil.

[0026] Furthermore, the connecting unit includes a first connecting block 108 and a second connecting block 109. The first connecting block 108 is fixedly connected to the fixed shell 106 and is located above the fixed shell 106. The second connecting block 109 is fixedly connected to the fixed shell 106 and is located above the fixed shell 106.

[0027] In this embodiment, the first connecting block 108 and the second connecting block 109 connect the fixed shell 106 and the moving block 112 into one unit. When the moving block 112 moves in the first moving groove 110 and the second moving groove 111, the connecting unit can drive the fixed shell 106 and the first limiting block 104 and the second limiting block 105 inside to move synchronously.

[0028] Further, the moving component includes a first moving groove 110, a second moving groove 111, a moving block 112, and a driving unit. The moving block 112 is detachably connected to the first connecting block 108 and is located above the first connecting block 108. The moving block 112 is also detachably connected to the second connecting block 109. The first moving groove 110 is fixedly connected to the mounting plate 101 and is located on one side of the mounting plate 101. The first moving groove 110 is slidably connected to the moving block 112. The second moving groove 111 is fixedly connected to the mounting plate 101 and is located on one side of the mounting plate 101. The second moving groove 111 is slidably connected to the moving block 112. The driving unit is disposed above the fixed housing 106.

[0029] In this embodiment, the first moving groove 110 and the second moving groove 111 provide a sliding track for the moving block 112, increasing its stability during movement; the control of the drive unit can precisely adjust the position of the moving block 112, thereby adjusting the relative position of the limiting block and the coil.

[0030] Furthermore, the drive unit includes a drive rod 113, a gear 114, and a rack 115. The drive rod 113 is rotatably connected to the moving block 112 and passes through the moving block 112. The gear 114 is detachably connected to the drive rod 113 and is located above the drive rod 113. The rack 115 is detachably connected to the second moving groove 111 and is located above the second moving groove 111. The gear 114 meshes with the rack 115.

[0031] In this embodiment, the starting of the mobile motor 117 drives the drive rod 113 to rotate, and the drive rod 113 drives the gear 114 to rotate. Since the gear 114 meshes with the rack 115, the rotation of the gear 114 is converted into the linear movement of the moving block 112 along the direction of the rack 115, thereby achieving precise control of the position of the clamping component.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
