DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0027] The present utility model provides a polyester fiber production cutting machine that is easy to protect as Figures 1-5 shown, including a base 1 for supporting the production and cutting of polyester fibers;

[0028] The first conveying assembly 2 is arranged on one side above the base 1 and is used for conveying polyester fibers. A protective cover 3 is fixedly arranged above the base 1, and a second conveying assembly 10 is obliquely arranged on the other side above the base 1;

[0029] The protection mechanism 4 is arranged above the protective cover 3 for protection. A hydraulic cylinder 5 is fixedly arranged above the protective cover 3. A connecting frame 6 is fixedly installed at the lower end of the hydraulic cylinder 5. A cutting knife 7 is fixedly arranged below the connecting frame 6. Protective components 8 are arranged on both sides of the connecting frame 6. A support block 9 is fixedly installed inside the upper part of the base 1;

[0030] The dust suction mechanism 11 is arranged inside the base 1 for dust suction. First, by turning on the switch of the air cylinder 401, the connecting block 402 is pushed to expand and contract. During the pushing process of the connecting block 402, through the rotation between the movable block 403 and the connecting rod 404, the protective plate 405 on one side of the movable block 403 is flipped on the protective cover 3, thus covering one side of the protective cover 3 to play a protective role. After that, when the polyester fiber is conveyed to the cutting area, by turning on the switch of the hydraulic cylinder 5, the connecting frame 6 and the cutting knife 7 are pushed to descend. During the descending process, the telescopic plates 803 on both sides first come into contact with the support block 9, playing a role in protecting the area around the cutting area cut by the cutting knife 7, thereby preventing the fragments broken by the cutting knife 7 from splashing out.

[0031] As Figure 1 、 Figure 2 and Figure 3 shown, the protection mechanism 4 includes an air cylinder 401, a connecting block 402, a movable block 403, a connecting rod 404, and a protective plate 405. The air cylinder 401 is fixed on both sides above the protective cover 3. A connecting block 402 is fixedly installed at one end of the air cylinder 401. A movable block 403 is movably arranged on one side of the connecting block 402. Connecting rods 404 are arranged on both sides of the movable block 403. A protective plate 405 is fixedly installed on one side of the movable block 403. By pushing the connecting block 402 to expand and contract through the air cylinder 401, the movable block 403 and the connecting rod 404 rotate, and the protective plate 405 is flipped for protection. It can not only provide protection during working hours, but also facilitate the internal maintenance and cleaning when not working.

[0032] As Figure 3 shown, the connecting block 402 is movably connected to the movable block 403 and the connecting rod 404. The movable block 403 is symmetrically arranged with respect to the central axis of the protective plate 405. The movable block 403 and the connecting rod 404 are movably connected, so as to stably drive the movable block 403 and the protective plate 405 to flip.

[0033] As Figure 2 and Figure 4As shown in the figure, the protection component 8 includes a fixed sleeve 801, a fixed plate 802, a telescopic plate 803, and a spring 804. The fixed sleeve 801 is fixed to both sides below the connecting frame 6. The fixed plate 802 is movably connected inside the fixed sleeve 801. The lower end of the fixed plate 802 is fixedly installed with a telescopic plate 803. Springs 804 are arranged above the fixed plate 802. The hydraulic cylinder 5 is used to drive the connecting frame 6 and the telescopic plates 803 on both sides below to move up and down, so that the telescopic plate 803 touches the support block 9 first. However, the connecting frame 6 and the cutting knife 7 need to continue to press down. Therefore, the telescopic plate 803 can be telescoped inside the fixed sleeve 801 to cooperate with the cutting knife 7 to press down and cut.

[0034] As Figure 4 shown, the fixed sleeve 801 is telescopically connected to the telescopic plate 803. The springs 804 are evenly distributed inside the fixed sleeve 801. The multiple groups of springs 804 inside the fixed sleeve 801 have the effect of squeezing the telescopic plate 803 to expand and contract.

[0035] As Figure 1 、 Figure 2 and Figure 5 shown, the dust suction mechanism 11 includes a dust suction hood 1101, a dust suction pipe 1102, a dust suction box 1103, a filter screen 1104, and a fan 1105. The dust suction hood 1101 is installed inside the base 1. The dust suction pipe 1102 is fixedly connected below the dust suction hood 1101. One end of the dust suction pipe 1102 is provided with a dust suction box 1103. The filter screen 1104 is arranged inside the dust suction box 1103. The fan 1105 is arranged on the other side of the dust suction box 1103. After cutting, the broken wire falls into the dust suction hood 1101 between the two support blocks 9. By turning on the switch of the fan 1105, the broken wire in the dust suction hood 1101 is adsorbed into the dust suction pipe 1102 and the dust suction box 1103, which is convenient for collection and cleaning and saves the time for the staff to clean.

[0036] The working principle of this utility model: First, connect the external power supply, then turn on the switch of the air cylinder 401 to push the connecting block 402 to expand and contract. During the pushing process of the connecting block 402, through the rotation between the movable block 403 and the connecting rod 404, the protective plate 405 on one side of the movable block 403 flips on the protective cover 3, thus covering one side of the protective cover 3 to play a protective role. Then, put the polyester fiber on the first conveying component 2, turn on the switches of the first conveying component 2 and the second conveying component 10, so that the polyester fiber is conveyed to the cutting area inside the protective cover 3. Then, turn on the switch of the hydraulic cylinder 5 to drive the connecting frame 6, the cutting knife 7 and the protective components 8 on both sides below to lift and lower. The telescopic plate 803 below touches the support block 9 first, but the connecting frame 6 and the cutting knife 7 need to continue to descend onto the polyester fiber for cutting. Therefore, the spring 804 above the telescopic plate 803 is squeezed and contracted inside the fixed sleeve 801, so as to cooperate with the downward pressure of the cutting knife 7 to cut the polyester fiber. When the polyester fiber is cut, turn off the switch of the hydraulic cylinder 5, and lift and lower the entire connecting frame 6, the cutting knife 7 and the protective components 8 to the original position. At this time, the telescopic plate 803 extends out inside the fixed sleeve 801 through the resilience of the spring 804. When the polyester fiber is cut, it is easy to break the line. The broken line falls into the dust suction hood 1101 through the gap in the cutting area between the support blocks 9. Then, turn on the switch of the fan 1105 for adsorption, and adsorb the broken line in the dust suction hood 1101 into the dust suction pipe 1102 and the dust suction box 1103, so as to facilitate collection and cleaning. Finally, the cut polyester fiber is discharged from the second conveying component 10. Finally, when the device is not used, turn off the switches of the fan 1105, the first conveying component 2 and the second conveying component 10, and then cut off the external power supply. Just like this, the use process of this polyester fiber production cutting machine that is convenient for protection is completed.

[0037] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
