Description
Technical Field
[0001] This utility model relates to the field of textile technology, specifically to a transmission and guiding device for cross-laid webs. Background Technology
[0002] Cross-laying machines are key pieces of equipment widely used in nonwoven fabric production lines. Nonwoven fabrics, also known as non-woven textiles, are fabric-like materials made by directly forming and reinforcing fibers into a web without undergoing traditional textile processes. The main function of a cross-laying machine is to fold and lay the thin fiber web output from the carding machine to form a multi-layered fiber web with a certain thickness, width, and good uniformity, to meet the requirements of subsequent processing in terms of fiber weight, thickness, and other aspects.
[0003] During cross-laying, the fiber web needs to be folded and stacked to form a web layer with a certain thickness and uniformity. However, due to the inherent characteristics of the fiber web and the influence of factors such as airflow and mechanical vibration during the laying process, the thin fiber web may shift position during folding. This leads to poor uniformity in laying the thin fiber web, affecting the quality of the final product, such as uneven thickness and inconsistent strength distribution. To address this, we propose a transmission and guiding device for cross-laying. Utility Model Content
[0004] The purpose of this invention is to provide a transmission and guiding device for cross-laying fiber mesh, to solve the problem mentioned in the background art, where the thin fiber mesh experiences positional shifts during folding due to the inherent characteristics of the thin fiber mesh itself and the influence of factors such as airflow and mechanical vibration during the laying process. This leads to poor uniformity in the laying process, affecting the quality of the final product, such as uneven thickness and inconsistent strength distribution.
[0005] To solve the above problems, this utility model provides the following technical solution: a transmission guide device for cross-laying netting, wherein the transmission guide device for cross-laying netting is disposed inside the netting machine, and the transmission guide device for cross-laying netting includes a guide part:

A pressure roller that abuts against the thin fiber web is rotatably mounted on the bottom of the lifting frame. A guide plate for guiding the thin fiber web is installed on the top of the movable frame.
[0007] By adopting the above technical solution, the mobile frame can move laterally on the top of the support frame to flexibly adjust according to the changes in the falling position of the thin fiber web. The lifting frame can slide vertically at the bottom of the mobile frame, so that the pressure roller always keeps in contact with the thin fiber web and presses down the already laid fiber web. The guide plate can guide the thin fiber web to ensure the accurate direction of the thin fiber web during the laying process and improve the quality and efficiency of cross-laying.
[0008] Preferably, the guide has a groove formed on the top of the support frame, and sliders are provided on the bottom of both sides of the movable frame. The sliders are embedded in the groove and slide laterally with the support frame.
[0009] By adopting the above technical solution, the cooperation between the slider and the slide groove can provide a stable guiding effect for the lateral sliding of the mobile frame on the support frame.

A transmission belt is nested on the top of the power wheel and the auxiliary wheel. The transmission belt has teeth inside that mesh with the power wheel and the auxiliary wheel. The power wheel rotates to drive the transmission belt to rotate.
[0011] By adopting the above technical solution, the power can be transmitted to the transmission belt through the rotation of the drive wheel and the meshing of the teeth inside the transmission belt with the drive wheel and auxiliary wheel, so that the transmission belt can rotate stably.
[0012] Preferably, the transmission belt is provided in two sets, and the sides of both sets of transmission belts are connected to the sides of the movable frame. The transmission belt rotates to drive the movable frame to move.
[0013] By adopting the above technical solution, the mobile frame can be moved simultaneously by two sets of transmission belts, so that the force on the mobile frame is more even during the movement, avoiding tilting or jamming caused by uneven force.
[0014] Preferably, the guide part also has a power shaft that is laterally rotatably disposed inside the support frame. The side of the power shaft is provided with bevel teeth b. The bottom of the power wheel is provided with bevel teeth a. The bevel teeth a and bevel teeth b are meshed and connected. The side of the support frame is provided with a motor, and the output end of the motor is connected to the power shaft.
[0015] By adopting the above technical solution, the power shaft can be rotated by a motor, and the bevel tooth b on the power shaft meshes with the bevel tooth a at the bottom of the power wheel to transmit power to the power wheel.
[0016] Preferably, there are two drive wheels, and two bevel teeth b are correspondingly provided on the drive shaft, with the two bevel teeth b being mirror images of each other on the drive shaft.
[0017] By adopting the above technical solution, the two sets of transmission belts can rotate synchronously through the cooperation of two power wheels and the corresponding two bevel teeth b, ensuring that the force on both sides of the moving frame is uniform.
[0018] Preferably, the guide section also has two limiting grooves formed at the bottom of the movable frame, and the two lifting frames are respectively embedded in the two limiting grooves and vertically slidably connected to the movable frame.
[0019] By adopting the above technical solution, the vertical sliding of the lifting frame can be limited by the limiting groove, so that the lifting frame can only slide vertically at the bottom of the moving frame.
[0020] Preferably, the guide portion also has several springs disposed on the top of the lifting frame, the springs being located inside the limiting groove.
[0021] By adopting the above technical solution, the elastic effect of the spring can be utilized. When the pressure roller comes into contact with the thin fiber web, the spring can play a buffering and adjusting role, so that the pressure roller can better adapt to the thickness changes and surface unevenness of the thin fiber web.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a transmission guide device for cross-laying netting, wherein the transmission guide device for cross-laying netting is disposed inside the netting machine 1, and the transmission guide device for cross-laying netting includes a guide part 2.
[0032] The support frame 201 is detachably fixed inside the web laying machine 1 by bolts. The movable frame 206 is laterally slidably disposed on the top of the support frame 201. The top of the support frame 201 is provided with a power source for driving the movable frame 206 to move laterally. The movable frame 206 is displaced to adapt to changes in the falling position of the thin fiber web. The lifting frame 210 is vertically slidably nested at the bottom of the movable frame 206. The bottom of the lifting frame 210 is rotatably disposed with a pressure roller 211 that abuts against the thin fiber web. The top of the movable frame 206 is provided with a guide plate 207 for guiding the thin fiber web. The movable frame 206 can move laterally on the top of the support frame 201 to flexibly adjust according to changes in the falling position of the thin fiber web. The lifting frame 210 can slide vertically at the bottom of the movable frame 206, so that the pressure roller 211 always keeps in contact with the thin fiber web and presses down the already laid fiber web. The guide plate 207 can guide the thin fiber web to ensure the accurate orientation of the thin fiber web during the web laying process and improve the quality and efficiency of cross-laying.
[0033] Example 2
[0034] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a transmission and guiding device for cross-laying netting, including a guide part 2:
[0035] A groove 202 is provided on the top of the support frame 201, and sliders 209 are provided on the bottom of both sides of the movable frame 206. The sliders 209 are embedded in the groove 202 and slide laterally with the support frame 201. The cooperation between the sliders 209 and the groove 202 can provide a stable guiding effect for the lateral sliding of the movable frame 206 on the support frame 201.
[0036] A power wheel 203 and an auxiliary wheel 205 are vertically rotatably mounted on the top of the support frame 201. A transmission belt 216 is nested on the top of the power wheel 203 and the auxiliary wheel 205. The transmission belt 216 has teeth inside that mesh with the power wheel 203 and the auxiliary wheel 205. The rotation of the power wheel 203 drives the transmission belt 216 to rotate. Through the rotation of the power wheel 203, the power is transmitted to the transmission belt 216 by utilizing the meshing of the teeth inside the transmission belt 216 with the power wheel 203 and the auxiliary wheel 205, so that the transmission belt 216 can rotate stably.
[0037] Two sets of transmission belts 216 are provided, and the sides of both sets of transmission belts 216 are connected to the sides of the movable frame 206. The transmission belts 216 rotate to drive the movable frame 206 to move. The movable frame 206 can be driven to move simultaneously by the two sets of transmission belts 216, so that the movable frame 206 is subjected to more even force during movement, avoiding tilting or jamming caused by uneven force.
[0038] A power shaft 213 is horizontally arranged inside the support frame 201. A bevel tooth b214 is provided on the side of the power shaft 213, and a bevel tooth a204 is provided on the bottom of the power wheel 203. The bevel tooth a204 meshes with the bevel tooth b214. A motor 215 is provided on the side of the support frame 201, and the output end of the motor 215 is connected to the power shaft 213. The motor 215 is specifically a stepper motor, which is a type of motor that converts electrical pulse signals into angular or linear displacement. Its working principle is based on the interaction of electromagnetic induction and magnetic fields. Precise position and speed control is achieved by controlling the number and frequency of electrical pulses. This is existing technology and will not be elaborated further below. When selecting a model, its power should be selected to suit the needs of the device to ensure that the object to be driven is driven. The power shaft 213 can be rotated by the motor 215. The bevel tooth b214 on the power shaft 213 meshes with the bevel tooth a204 at the bottom of the power wheel 203, transmitting power to the power wheel 203.
[0039] There are two drive wheels 203, and two bevel teeth b214 are correspondingly provided on the drive shaft 213. The two bevel teeth b214 are mirrored on the drive shaft 213. Through the cooperation of the two drive wheels 203 and the corresponding two bevel teeth b214, the two sets of transmission belts 216 can rotate synchronously, ensuring that the force on both sides of the moving frame 206 is uniform.
[0040] Two limiting grooves 208 are provided at the bottom of the movable frame 206. Two lifting frames 210 are vertically slidably embedded in the two limiting grooves 208. The vertical sliding of the lifting frames 210 can be limited by the limiting grooves 208, so that the lifting frames 210 can only slide vertically at the bottom of the movable frame 206.
[0041] Several springs 212 are provided on the top of the lifting frame 210. The springs 212 are located inside the limiting groove 208. The elastic effect of the springs 212 can be used to buffer and adjust when the pressure roller 211 contacts the thin fiber web, so that the pressure roller 211 can better adapt to the thickness change and surface unevenness of the thin fiber web.
[0042] Working principle: First, the motor 215 is started. The output end of the motor 215 drives the power shaft 213 to rotate. The bevel teeth b214 on the side of the power shaft 213 mesh with the bevel teeth a204 at the bottom of the power wheel 203. The rotation of the power shaft 213 is transmitted to the power wheel 203 through the engagement of the bevel teeth b214 and a204, causing the power wheel 203 to start rotating. Since the top of the power wheel 203 and the auxiliary wheel 205 are nested with a transmission belt 216, and the transmission belt 216... The internal teeth of the 6 engage with the drive wheel 203 and the auxiliary wheel 205. The rotation of the drive wheel 203 drives the transmission belt 216 to rotate stably. Since there are two sets of transmission belts 216, and the sides of both sets of transmission belts 216 are connected to the sides of the movable frame 206, the rotation of the transmission belts 216 will drive the movable frame 206 to move laterally on the top of the support frame 201. During the movement of the movable frame 206, the sliders 209 on both sides of its bottom are engaged with the grooves on the top of the support frame 201. Inside 202, a stable guiding function is provided for the lateral sliding of the moving frame 206, ensuring that the moving frame 206 moves smoothly and steadily to adapt to changes in the falling position of the thin fiber web. During the thin fiber web laying process, the guide plate 207 at the top of the moving frame 206 guides the thin fiber web to ensure accurate orientation. At the same time, the lifting frame 210 at the bottom of the moving frame 206 is vertically slidably connected to the moving frame 206 through an embedded limiting groove 208. The pressure roller 211 at the bottom of the lifting frame 210 rotates and abuts against the thin fiber web. When the pressure roller 211 contacts the thin fiber web, the elasticity of the springs 212 located inside the limiting groove 208 at the top of the lifting frame 210 acts as a buffer and adjuster, allowing the pressure roller 211 to better adapt to changes in the thickness and unevenness of the thin fiber web, always maintaining a good contact with the thin fiber web, thereby pressing down the already laid fiber web and further improving the quality and efficiency of cross-laying.
