[0024] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 5 , for the automatic splicing device for non-twisted long filament fibers in this embodiment, a chamber 11 is provided on the workbench 1, and a splicing part 2 is provided within the area of the chamber 11. The splicing part 2 includes a mutually cooperating tensioning assembly 21 and a processing assembly 22. The tensioning assembly 21 and the processing assembly 22 act on the long filament fibers successively, and splicing processing is performed after the long filament fibers are tensioned. The device further includes a first erection assembly 3 and a second erection assembly 4, and the first erection assembly 3 and the second erection assembly 4 are respectively located on the surface of the workbench 1 on both sides of the chamber 11.

[0025] Further, the first erection assembly 3 includes a first frame 31 and a second frame 32 arranged along a first direction. In this embodiment, the first direction is the direction perpendicular to the surface of the workbench 1, that isFigure 2 The vertical direction shown. At one end of the first frame body 31 away from the workbench 1, there is also an extension section 311 perpendicular to the first direction. The guiding members 5 are respectively rotatably arranged at one end of the extension section 311 and at one end of the second frame body 32 away from the workbench 1. The guiding members 5 are close to each other. Preferably, the guiding member 5 arranged on the first frame body 31 can be arranged at the end of the extension section 311. Through the rotational arrangement of the guiding members 5, on the one hand, it can guide the filament fibers, and on the other hand, it can also adjust the steering in real time when the first frame body 31 and the second frame body 32 are transposed, preventing the filament fibers from being entangled with each other. The first frame assembly 3 further includes a rotary cylinder 33. The rotary cylinder 33 is rotatably arranged on the workbench 1. The first frame body 31 and the second frame body 32 are both arranged on the rotary cylinder 33. Through the rotary cylinder 33, the positions of the first frame body 31 and the second frame body 32 are swapped each time after splicing to improve production efficiency. The height of the first frame body 31 in the first direction is higher than the height of the second frame body 32 in the first direction. Through the different heights of the first frame body 31 and the second frame body 32 and in combination with the arrangement of the extension section 311, when the first frame body 31 and the second frame body 32 are transposed along with the rotary cylinder 33, by setting the rotation angle of the rotary cylinder 33, it can be realized that while the first frame body 31 and the second frame body 32 are transposed on both sides in the second direction, the filament fibers connected to the second frame body 32 can be adjusted within the length range of the extension section 311 without entanglement.

[0026] Furthermore, the second frame assembly 4 includes a fifth frame body 41. The fifth frame body 41 is arranged in the first direction and is connected with the rotatable guiding member 5 at one end away from the workbench 1. The second frame assembly 4 further includes a support member 42 and a clamping member 43. The support member 42 is arranged on the surface of the workbench 1. The fifth frame body 41 and the clamping member 43 are both arranged on the support member 42. In this embodiment, two clamping members 43 are provided to increase the tension of the filament fibers.

[0027] Furthermore, the tensioning assembly 21 includes a connecting plate 211 and a lifting cylinder 212. The lifting cylinder 212 acts on the connecting plate 211 to move in the first direction to realize the switching between the first state and the second state. In this embodiment, the first state is the situation where the connecting plate 211 is farthest from the workbench 1. Correspondingly, the second state is the situation where the connecting plate 211 is closest to the workbench 1.

[0028] Further, the tensioning assembly 21 further includes a pressure plate assembly 213, the pressure plate assembly 213 includes a fixed plate 2131 and a movable plate 2132, the movable plate 2132 is movable along a first direction relative to the fixed plate 2131, the pressure plate assembly 213 is symmetrically arranged at both ends of the connecting plate 211 and the fixed plates 2131 are close to each other. In the first state of the connecting plate 211, the bottom height of the fixed plate 2131 along the first direction is higher than the bottom height of the movable plate 2132 and higher than the center height of the guide member 5 on the fifth frame 41. The fixed plate 2131 includes a recessed portion 21311, and the recessed portion 21311 is matched with the chamber 11.

[0029] Specifically, when the lifting cylinder 212 drives the connecting plate 211 to change from the first state to the second state, the bottom height of the movable plate 2132 is lower than the bottom height of the fixed plate 2131 under the action of gravity, that is, the movable plate 2132 contacts the workbench 1 before the fixed plate 2131 to initially tension the filament fibers, and then the fixed plate 2131 contacts the workbench 1, that is, the recessed portion 21311 of the fixed plate 2131 is partially stuck at the edge of the chamber 11 to perform secondary tensioning and fixation on the filament fibers.

[0030] Furthermore, the processing assembly 22 includes a motor 221, a coupling 222 and a sensor 223. The motor 221 acts on the coupling 222, the lifting cylinder 212, the rotary cylinder 33 and the linear cylinder 36. The sensor 223 is also matched with the coupling 222. In this embodiment, the coupling 222 is configured to rotate one circle to achieve a single splicing of the filament fiber, and then the rotation state of the coupling 222 is detected by the sensor 223. The processing assembly 22 also includes a stopper 224, a slice 225 and a splicer 226, which are all matched with the coupling 222. The stopper 224 is symmetrically arranged about the second direction and a hook 2241 close to each other is arranged at the end away from the workbench 1. The splicer 226 is collinear with the center of the support member 42 along the second direction to ensure the smoothness of the production operation of the device. In this embodiment, the second direction is a direction parallel to the long side of the workbench 1 and passing through the center of the splicer 226. The hook 2241 is provided to effectively prevent the filament fibers from escaping from the working range of the splicer 226 during the splicing process, thereby improving the stability of the production process. The slices 225 are symmetrical about the center of the splicer 226, that is, they are respectively provided on both sides of the splicer 226, and the two strands of filament fibers used in this embodiment are staggered and cut.

[0031] Embodiment 2: Please continue reading Figures 3 to 5, the structure of the second embodiment is the same as that of the first embodiment, except only for the first erection component 3. The first erection component 3 includes a third frame body 34 and a fourth frame body 35 arranged along the first direction. Rotatable guides 5 are respectively provided at one ends of the third frame body 34 and the fourth frame body 35 away from the workbench 1. The first erection component 3 further includes linear cylinders 36 respectively connected to the third frame body 34 and the fourth frame body 35. The extending directions between the linear cylinders 36 are close to each other. The heights of the third frame body 34 and the fourth frame body 35 along the first direction are different. By extending and retracting the linear cylinders 36, the positions of the third frame body 34 and the fourth frame body 35 on both sides in the second direction are swapped back and forth. The second erection component 4 further includes a support member 42 and a clamping member 43. The fifth frame body 41 and the clamping member 43 are both arranged on the support member 42, and the support member 42 is arranged on the surface of the workbench 1.

[0032] The splicing process of this embodiment is applied to the above long filament fiber automatic splicing device, and includes the following steps: First, the long filament fibers are respectively threaded through the guides 5 on the first frame body 31 and the second frame body 32 or the third frame body 34 and the fourth frame body 35. Then, after the two long filament fibers pass through the splicer 226, one long filament fiber passes through the guide 5 on the fifth frame body 41 and is connected to an external conveying mechanism, while the other long filament fiber is clamped by the clamping member 43 to complete the preliminary work. Then the motor 221 drives the lifting cylinder 212 to descend, driving the connecting plate 211 to press down, that is, changing the connecting plate 211 from the first state to the second state.

[0033] The movable plate 2132 and the fixed plate 2131 act on the two long filament fibers in sequence to tension them to facilitate splicing the long filament fibers. Then the motor 221 drives the coupling 222 and makes the splicer 226 and the slicer 225 act in sequence to splice the long filament fibers and cut off part of the long filament fibers. Finally, the motor 221 drives the lifting cylinder 212 to rise again, that is, changing the connecting plate 211 from the second state to the first state. At the same time, the motor 221 drives the rotary cylinder 33 to make the first frame body 31 and the second frame body 32 change positions, or the linear cylinder 36 makes the third frame body 34 and the fourth frame body 35 change positions for cross-operation, and then continues to thread the long filament fibers and work continuously.

[0034] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.

[0035] The embodiments described above merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
