[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The conveyor belt transports the non-woven fabric, and then the sidewall of the non-woven fabric contacts the sidewalls of two positioning plates, limiting the movement of the non-woven fabric. Then, the output end of the electric actuator pushes the movable plate downward, causing the cutter to contact the non-woven fabric. With the cooperation of the support plate, the non-woven fabric is cut to a fixed length. The design of the positioning plate ensures that the non-woven fabric is limited before cutting, ensuring the accuracy of the cutting length, avoiding movement during the cutting process, and improving the cutting precision. At the same time, the cooperation of the support plate provides stable support for the cutter during the cutting process, avoiding inaccurate cutting caused by the elasticity of the conveyor belt.

[0014] 2. When the cutting length of the non-woven fabric needs to be adjusted, the screw is driven to rotate by the output end of the stepper motor. The screw and the movable frame are then connected by a thread, allowing the end of the movable frame to slide laterally. The sliding distance of the movable frame can be visually observed through the cooperation between the scale and the arrow block. The cutter is then adjusted to the position where the non-woven fabric needs to be cut. By adjusting the position of the cutter, the cutting device can flexibly adapt to different cutting length requirements, enhancing the flexibility and adaptability of the device. At the same time, the design of the scale and arrow block not only facilitates the operator's adjustment operation but also helps to reduce errors during the adjustment process and improve the accuracy of cutting.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A gentian lyocell nonwoven fabric fixed-length cutting device includes a base 001, with two sliding grooves 101 on the upper end of the base 001. A motor 105 is fixedly connected inside the lower end of the base 001. Two synchronous gears 106 and a gear 108 are rotatably connected inside the base 001. The output end of the motor 105 is fixedly connected to the lower end of one of the synchronous gears 106. A synchronous belt 107 is fitted around both synchronous gears 106, and one of the synchronous gears 106 meshes with the gear 108. A movable frame 002 is slidably disposed on the upper end of the base 001. The lower end of the movable frame 002 is slidably connected to the sliding grooves 101. An electric push rod 201 is fixedly connected to the upper end of the movable frame 002. A movable plate 202 is slidably connected between the inner side walls. The upper end of the movable plate 202 is fixedly connected to the output end of the electric push rod 201, and the lower end of the movable plate 202 is fixedly connected to the cutter 203. Two vertical plates 003 are fixedly mounted on the upper end of the base 001. A conveyor belt 303 is provided between the side walls of the two vertical plates 003. Each side wall of the two vertical plates 003 is provided with a groove 306. A positioning plate 307 is rotatably connected inside the groove 306. A rod 308 is fixedly connected to the lower end of the positioning plate 307. The end of one rod 308 is fixedly connected to the upper end of one of the synchronous gears 106, and the end of the other rod 308 is fixedly connected to the upper end of the gear 108. An external conveying device places the non-woven fabric to be cut onto the conveyor belt 303. On surface 03, the non-woven fabric is conveyed and moved by the conveyor belt 303. Then, the sidewall of the non-woven fabric contacts the sidewalls of the two positioning plates 307, limiting the movement of the non-woven fabric. The conveyor belt 303 stops operating. Then, the output end of the electric actuator 201 pushes the movable plate 202 downwards, causing the cutter 203 to contact the non-woven fabric and cut it to a fixed length. After cutting, the output end of the motor 105 drives one of the synchronous gears 106 to rotate. Simultaneously, one of the synchronous gears 106 drives one of the rods 308 to rotate in the opposite direction. Through the transmission of the synchronous belt 107, the other synchronous gear 106 rotates synchronously. Then, through the engagement between the other synchronous gear 106 and gear 108, the gears... 108 drives another rod 308 to rotate in the forward direction, thereby causing the two positioning plates 307 to rotate in opposite directions. The positioning plates 307 rotate into the groove 306. Then the conveyor belt 303 operates, transporting the cut nonwoven fabric to the subsequent processing device. Then the two positioning plates 307 rotate relative to each other, and the positioning plates 307 rotate out from the groove 306 to prepare for the subsequent nonwoven fabric cutting. Then the next piece of nonwoven fabric to be cut is transported to the upper end of the conveyor belt 303 through the external conveying device. When it is necessary to adjust the cutting length of the nonwoven fabric, the movable frame 002 slides laterally a suitable distance to adjust the cutter 203 to the position where the nonwoven fabric needs to be cut. Both synchronous gears 106 and gear 108 are spur gears.

[0023] One of the slide grooves 101 has a screw 102 rotatably connected inside, and a stepper motor 103 is fixedly connected inside the upper end of the base 001. The output end of the stepper motor 103 is fixedly connected to the end of the screw 102. The screw 102 is threadedly connected to the movable frame 002. The output end of the stepper motor 103 drives the screw 102 to rotate. Then, through the threaded engagement between the screw 102 and the movable frame 002, the end of the movable frame 002 slides laterally inside the slide groove 101.

[0024] A ruler 104 is fixedly connected to the side wall of the base 001, and an arrow block 205 is fixedly connected to the side wall of the movable frame 002. The ruler 104 and the arrow block 205 cooperate to visually display the distance of the movable frame 002 sliding laterally through the cooperation between the ruler 104 and the arrow block 205.

[0025] The upper end of the movable frame 002 is slidably connected to two vertical rods 204. The lower end of the vertical rods 204 is fixedly connected to the upper end of the movable plate 202. The two vertical rods 204 guide and limit the longitudinally sliding movable plate 202.

[0026] A main roller 301 and a roller body 302 are rotatably connected between two vertical plates 003. A conveyor belt 303 is respectively sleeved on the outside of the main roller 301 and the roller body 302. A drive motor 304 is fixedly connected to the side wall of one of the vertical plates 003. The output end of the drive motor 304 is fixedly connected to the end of the main roller 301. The main roller 301 is driven to rotate through the output end of the drive motor 304. Then, through the cooperation of the roller body 302, the conveyor belt 303 operates, thereby conveying the nonwoven fabric.

[0027] A support plate 305 is fixedly connected between the side walls of the two vertical plates 003. The upper end of the support plate 305 is in contact with the lower surface of the conveyor belt 303. When the cutter 203 cuts the non-woven fabric, the support plate 305 supports the conveyor belt 303 to avoid the problem of not being able to cut the non-woven fabric due to the elasticity of the conveyor belt 303.

[0028] In this invention, an external conveying device places the nonwoven fabric to be cut on the surface of the conveyor belt 303. The main roller 301 is driven to rotate by the output end of the drive motor 304. With the cooperation of the roller body 302, the conveyor belt 303 operates to transport and move the nonwoven fabric. Then, the side wall of the nonwoven fabric contacts the side wall of the two positioning plates 307 to limit the nonwoven fabric. The conveyor belt 303 stops operating. Then, the output end of the electric push rod 201 pushes the movable plate 202 to slide downward, so that the cutter 203 contacts the nonwoven fabric. With the cooperation of the support plate 305, the nonwoven fabric is cut to a fixed length.

[0029] After the nonwoven fabric is cut, the output of motor 105 drives one of the synchronous gears 106 to rotate. At the same time, one of the synchronous gears 106 drives one of the rods 308 to rotate in the opposite direction. Through the transmission of synchronous belt 107, the other synchronous gear 106 rotates synchronously. Through the cooperation between the other synchronous gear 106 and gear 108, gear 108 drives the other rod 308 to rotate in the forward direction. As a result, the two positioning plates 307 rotate in opposite directions and rotate into the groove 306. Then, the conveyor belt 303 operates to transport the cut nonwoven fabric to the subsequent processing device. Then, the two positioning plates 307 rotate relative to each other and rotate out of the groove 306 to prepare for the subsequent nonwoven fabric cutting. Then, the next piece of nonwoven fabric to be cut is transported to the upper end of the conveyor belt 303 through an external conveying device.

[0030] When the cutting length of the nonwoven fabric needs to be adjusted, the screw 102 is driven to rotate by the output end of the stepper motor 103. Then, through the threaded engagement between the screw 102 and the movable frame 002, the end of the movable frame 002 slides laterally. The sliding distance of the movable frame 002 can be visually observed through the engagement between the scale 104 and the arrow block 205. After the cutter 203 is adjusted to the position where the nonwoven fabric needs to be cut, the stepper motor 103 stops operating.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
