[0002] An equal-length cutting device is a device used to cut continuously supplied materials such as fibers, tapes, etc. according to a preset length. It is usually used in manufacturing to cut continuous raw materials into small segments of the same length for subsequent processing or use. Long glass fiber is a high-performance fiber-reinforced material, usually used in the manufacture of various production materials such as glass fiber boards and glass fiber sleeves. In the production of glass fiber sleeves, an equal-length cutting device is required to cut and segment the glass fiber sleeves;

[0003] According to the Chinese patent application number: 202022719250.4, there is disclosed a fixed-length cutting device for glass fiber sleeve production, including a workbench and a fixed-length adjustment seat and a positioning cutting seat respectively arranged at both ends of the workbench. The fixed-length adjustment seat and the positioning cutting seat are hollow structures, and a number of side-by-side arranged guide holes are respectively opened on both sides of the two; a first positioning groove is opened in the middle of the top surface of the fixed-length adjustment seat, a cutting groove is opened in the middle of the top surface of the positioning cutting seat, and second positioning grooves are symmetrically arranged on both sides of the cutting groove on the top surface of the positioning cutting seat. A lifting plate for embedding into the groove body is respectively arranged above the first positioning groove, the cutting groove and the second positioning groove, and a cutting blade is installed on the bottom surface of the lifting plate above the cutting groove; lifting mechanisms for driving the lifting of each lifting plate are respectively arranged at both ends of the lifting plate; a batch loosening mechanism for glass fiber sleeves is arranged at one end of the workbench close to the fixed-length adjustment seat;

In the present disclosure, aspects of the present utility model are described with reference to the drawings, and many illustrative embodiments are shown in the drawings. The embodiments of the present disclosure do not necessarily define all aspects of the present utility model. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the present utility model are not limited to any embodiment. In addition, some aspects of the present utility model can be used alone, or in any suitable combination with other aspects of the present utility model.

[0022] Embodiment 1

[0023] As Figures 1-4 shown, this is the first embodiment of the present utility model. This embodiment provides an equal-length cutting device for long glass fiber production, including a bracket 1. A cutting mechanism 2 is installed on the top of the bracket 1. The cutting mechanism 2 includes a cutting assembly 21 and a limiting assembly 22. A positioning assembly 3 is installed on one side of the bracket 1. The positioning assembly 3 includes a positioning frame 301, an L-shaped plate 302, a contact sensor 303, a threaded rod 304, a second motor 305, a chute 306, a slider 307, a scale line 308, a PLC controller 309, a ranging sensor 310, and a control panel 311. The positioning frame 301 is fixedly connected to the bracket 1. The scale line 308 is arranged on the top of the positioning frame 301. The L-shaped plate 302 is located on the top of the positioning frame 301. The contact sensor 303 is installed in the inner cavity of the L-shaped plate 302. The ranging sensor 310 and the control panel 311 are respectively installed at the front end and the rear end of the top of the bracket 1. The PLC controller 309 is installed in the inner cavity of the bracket 1. The output ends of the contact sensor 303, the ranging sensor 310, and the control panel 311 are all connected to the input end of the PLC controller 309. A conveying frame 4 is fixedly connected to the other side of the bracket 1.

[0024] As Figures 1-4 shown, the output shaft of the second motor 305 rotates to drive the threaded rod 304 to rotate. When the threaded rod 304 rotates, it drives the slider 307 to move along the surface of the threaded rod 304. When the slider 307 moves, it drives the L-shaped plate 302 to move along the inner cavity of the chute 306. While the L-shaped plate 302 moves, it drives the contact sensor 303 to move, so that the position of the contact sensor 303 can be adjusted. The position of the contact sensor 303 can be accurately adjusted through the scale line 308. By adjusting the position of the contact sensor 303, the cutting length can be preset. The cutting length can be positioned through the contact sensor 303 and the ranging sensor 310. Conveying rollers can be installed on the surface of the conveying frame 4 to convey the glass fiber sleeve. When one end of the glass fiber sleeve contacts the contact sensor 303, the contact sensor 303 sends a signal to the PLC controller 309, and the PLC controller 309 controls the cutting mechanism 2 to cut the glass fiber sleeve, so that equal-length cutting can be realized, effectively improving the accuracy of equal-length cutting.

[0025] Embodiment 2

[0026] Referring to Figure 1 and 2 4, this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0027] In this embodiment, the threaded rod 304 is installed in the inner cavity of the positioning frame 301. One end of the threaded rod 304 is movably connected to the inner wall of the positioning frame 301 through a bearing. The second motor 305 is fixedly connected to the positioning frame 301. The output shaft of the second motor 305 penetrates into the inner cavity of the positioning frame 301 and is in transmission connection with the threaded rod 304.

[0028] The slider 307 is sleeved on the surface of the threaded rod 304 and is threadedly connected to the threaded rod 304. The chute 306 is opened at the top of the positioning frame 301. One end of the slider 307 away from the threaded rod 304 penetrates through the chute 306 and is fixedly connected to the L-shaped plate 302 and is slidably connected to the inner cavity of the chute 306.

[0029] As Figure 1 、 2 As shown in 4, the cutting parameters can be set through the control panel 311. The control panel 311 is used to manually control the start and stop of the cutting assembly 21 and the limiting assembly 22, so that an emergency stop operation can be performed in case of emergency. The model of the PLC controller 309 can be selected as CP1 L-M60DT-D. Through the double positioning of the ranging sensor 310 and the control panel 311, the accuracy of equal-length cutting can be ensured. When the output shaft of the second motor 305 rotates forward, it can drive the L-shaped plate 302 to approach the bracket 1. When the output shaft of the second motor 305 rotates reversely, it can drive the L-shaped plate 302 away from the bracket 1, so that the position of the contact sensor 303 can be adjusted.

[0030] Embodiment 3

[0031] Referring to Figure 1 、 3 And 4, this is the third embodiment of the present invention. This embodiment is based on the first two embodiments.

[0032] In this embodiment, the cutting assembly 21 includes a housing 211, a first cylinder 212, a cutting blade 213 and a first motor 214. One end of the first cylinder 212 is movably connected to the bracket 1 through a movable pin. The output end of the first cylinder 212 is movably connected to the housing 211 through a movable pin. The bottom of the housing 211 is movably connected to the top of the bracket 1 through a movable pin.

[0033] The first motor 214 is installed on one side of the inner cavity of the housing 211. The cutting blade 213 is installed on the other side of the inner cavity of the housing 211. The output shaft of the first motor 214 is fixedly connected to the cutting blade 213.

[0034] The limiting assembly 22 includes a second cylinder 221 and a limiting plate 222. The second cylinder 221 is fixed to the top of the bracket 1. The output end of the second cylinder 221 is fixedly connected to the limiting plate 222. The output end of the PLC controller 309 is respectively connected to the input ends of the first cylinder 212, the first motor 214, the second cylinder 221 and the second motor 305.

[0035] As Figure 1 , 3 and shown in Figure 4, after the positioning component 3 positions the cutting position of the glass fiber sleeve, the PLC controller 309 sequentially starts the second cylinder 221, the first motor 214 and the first cylinder 212. The output end of the second cylinder 221 extends to push the limiting plate 222 to fix the glass fiber sleeve, preventing the glass fiber sleeve from shifting during cutting. The output end of the first cylinder 212 extends to push the housing 211 downward, so that the cutting blade 213 contacts the glass fiber sleeve. The output shaft of the first motor 214 rotates to drive the cutting blade 213 to cut the glass fiber sleeve.

[0036] During use, first set the equal-length cutting length. The output shaft of the second motor 305 rotates to drive the threaded rod 304 to rotate. When the threaded rod 304 rotates, it drives the slider 307 to move along the surface of the threaded rod 304. When the slider 307 moves, it drives the L-shaped plate 302 to move along the inner cavity of the chute 306. While the L-shaped plate 302 moves, it drives the contact sensor 303 to move, so as to be able to adjust the position of the contact sensor 303. The position of the contact sensor 303 can be accurately adjusted through the scale line 308. By adjusting the position of the contact sensor 303, the cutting length can be preset. Then, the glass fiber sleeve is conveyed by the conveying frame 4. The distance measuring sensor 310 locates the length of the glass fiber sleeve by using the infrared principle. When one end of the glass fiber sleeve contacts the contact sensor 303, the contact sensor 303 sends a signal to the PLC controller 309. The PLC controller 309 sequentially starts the second cylinder 221, the first motor 214 and the first cylinder 212. The output end of the second cylinder 221 extends to push the limiting plate 222 to fix the glass fiber sleeve, preventing the glass fiber sleeve from shifting during cutting. The output end of the first cylinder 212 extends to push the housing 211 downward, so that the cutting blade 213 contacts the glass fiber sleeve. The output shaft of the first motor 214 rotates to drive the cutting blade 213 to cut the glass fiber sleeve. In this way, the glass fiber sleeve can be cut with equal length, effectively improving the accuracy of equal-length cutting.
