Description

Technical Field

[0001] This utility model relates to the field of wet web forming and calendering technology, and in particular to a device for adjusting the uniform thickness of cotton towels. Background Technology

[0002] As consumers continue to demand higher quality personal care products (such as pursuing softer, more absorbent cotton wipes), and as environmental policies drive the trend of biodegradable materials replacing traditional chemical raw materials, dynamic pressure adjustment and precise dehydration are required for the evenly distributed wet paper web during the production of nonwoven fabrics using wet web forming technology. This requires the use of adjustment devices. In practical use, similar adjustment devices still have many defects. For example, traditional adjustment devices with single-roller drive are prone to causing local slack or excessive tightness of the mesh belt, resulting in stretching and deformation of the wet paper web. At the same time, traditional adjustment devices with early hydraulic or pneumatic systems have response delays and are difficult to adapt to the real-time thickness correction requirements of high-speed production lines. Therefore, it is necessary to design a cotton towel thickness uniform adjustment device. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cotton towel thickness uniformity adjustment device.

[0004] This utility model is achieved using the following technical solution: a cotton towel thickness uniformity adjustment device, comprising a conveying assembly, the conveying assembly including a mounting frame, a drive roller and a transport roller rotatably connected inside the mounting frame, the drive roller and the transport roller being connected by a drive chain, and a conveyor mesh belt sleeved on the outer surfaces of the drive roller and the transport roller, further comprising: A compaction assembly, comprising a mounting plate fixedly connected to the top of a mounting frame, a rotating wheel rotatably connected inside the mounting plate, a movable seat movably mounted on one side of the rotating wheel via a guide rod, and a first movable groove provided at the bottom of the movable seat; The drive assembly includes a second servo motor fixedly connected to the top of the mounting plate via a connecting plate. A worm gear is fixedly connected to the output end of the second servo motor, and a worm wheel is provided on one side of the worm gear.

[0005] As a further improvement to the above solution, a first servo motor is fixedly connected to the outer surface of the mounting frame, a transmission roller is fixedly connected to the output end of the first servo motor, a collection rack is fixedly connected to the inner wall of the mounting frame, an inclined plate is fixedly connected to the inner wall of the collection rack, and a drainage hole is provided at the bottom of the collection rack.

[0006] Through the above technical solution, the transmission roller is directly driven by the first servo motor. Combined with the inclined design of the collection frame and the layout of the drainage holes, the directional collection and efficient discharge of wastewater after dewatering is achieved.

[0007] As a further improvement to the above solution, a guide rod is fixedly connected to the outer surface of the rotating wheel, and a movable seat is provided on the outer surface of the guide rod. A first movable groove is provided inside the movable seat, and the first movable groove is configured to be horizontal.

[0008] Through the above technical solution, the transverse movable groove limits the movement direction of the moving seat to a single axis, and in conjunction with the linear guiding effect of the guide rod, effectively eliminates the lateral offset error during the compaction process.

[0009] As a further improvement to the above solution, a rolling plate is fixedly connected to the bottom of the movable seat, and a second movable groove is provided at the top inside the movable seat. The second movable groove is set in the longitudinal direction, and a limit rod is slidably installed inside the second movable groove. The limit rod is fixedly connected to the outer surface of the mounting plate.

[0010] Through the above technical solution, this dual-dimensional constraint mechanism not only improves motion stability, but also prevents overload impact through mechanical limiting, thus extending the equipment's lifespan.

[0011] As a further improvement to the above solution, a connecting plate is fixedly connected to the outer surface of the mounting plate, a second servo motor is fixedly connected to the top of the connecting plate, and a worm gear is fixedly connected to the output end of the second servo motor through the connecting plate.

[0012] Through the above technical solution, the direct connection between the worm and the motor reduces transmission losses. Combined with the precision-machined tooth profile parameters, it achieves low backlash and high-response speed control, providing a stable input source for the subsequent worm gear transmission system.

[0013] As a further improvement to the above solution, a connecting plate is rotatably connected inside the mounting plate, and a guide rod is fixedly connected to one side of the outer surface of the connecting plate.

[0014] As a further improvement to the above solution, a worm gear is fixedly connected to the side of the outer surface of the connecting disc away from the guide rod, and the worm gear meshes with the worm.

[0015] The above technical solution offers lower noise and longer service life compared to gear systems, making it particularly suitable for production environments requiring frequent start-stop operations.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves stable clamping and linear transport of wet paper web by synchronously operating the drive roller, transport roller, and drive chain. This enables the smooth transport and tension balance control of fiber raw materials before pressing. The first servo motor drives the drive roller as a power source, and the torque is transmitted to the transport roller through the drive chain, forming a double-roller reverse traction mode. This mechanical linkage generates a continuous and uniform friction field on the surface of the conveyor belt, ensuring that the wet paper web will not be stretched or deformed due to overload, nor will it accumulate locally due to slippage, thus providing ideal initial conditions for subsequent pressing processes.

[0017] This invention utilizes the meshing transmission of a worm gear and a worm wheel, the motion conversion of a guide rod, and the trajectory constraint of a limiting rod to drive the moving seat to make precise reciprocating motion along a predetermined axis. This achieves dynamic adjustment of the pressure of the pressing plate on the wet paper web and controllable moisture discharge. When the second servo motor drives the worm gear to rotate, the meshing worm wheel drives the connecting disc to rotate synchronously. This, in turn, pushes the moving seat to slide up and down within the linear track defined by the limiting rod through the guide rod. This structure efficiently converts rotational motion into linear pressing action. Combined with the collection rack and inclined plate below the conveyor belt, it achieves precise matching between pressure value and dewatering amount, effectively improving the density uniformity and drying efficiency of the product.

Detailed Implementation

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0021] Please combine Figure 1-5 This embodiment of a cotton towel thickness uniformity adjustment device includes a conveying assembly 1. The conveying assembly 1 includes a mounting frame 101. A drive roller 102 and a transport roller 103 are rotatably connected inside the mounting frame 101. The drive roller 102 and the transport roller 103 are connected by a drive chain 104. A conveyor belt 105 is sleeved on the outer surface of the drive roller 102 and the transport roller 103. The device also includes: The compaction assembly 2 includes a mounting plate 201 fixedly connected to the top of the mounting frame 101. A rotating wheel 202 is rotatably connected inside the mounting plate 201. A movable seat 204 is movably mounted on one side of the rotating wheel 202 via a guide rod 203. A first movable groove 205 is provided at the bottom of the movable seat 204. The drive assembly 3 includes a second servo motor 302 fixedly connected to the top of the mounting plate 201 via a connecting plate 301. A worm gear 303 is fixedly connected to the output end of the second servo motor 302, and a worm wheel 304 is provided on one side of the worm gear 303.

[0022] A first servo motor 109 is fixedly connected to the outer surface of the mounting frame 101. A transmission roller 102 is fixedly connected to the output end of the first servo motor 109. A collection rack 106 is fixedly connected to the inner wall of the mounting frame 101. An inclined plate 107 is fixedly connected to the inner wall of the collection rack 106. A drainage hole 108 is provided at the bottom of the collection rack 106.

[0023] The pressing plate 206 applies uniform pressure to the wet paper. Excess water is squeezed out through the mesh of the conveyor belt 105 and falls into the collection rack 106 below. Under the guiding action of the inclined plate 107, the released water flows into the drain hole 108 along the preset path, finally completing the solid-liquid separation process.

[0024] A guide rod 203 is fixedly connected to the outer surface of the rotating wheel 202. A movable seat 204 is provided on the outer surface of the guide rod 203. A first movable groove 205 is provided inside the movable seat 204. The first movable groove 205 is configured to be horizontal.

[0025] A rolling plate 206 is fixedly connected to the bottom of the movable seat 204. A second movable groove 207 is provided at the top inside the movable seat 204. The second movable groove 207 is set in the longitudinal direction. A limit rod 208 is slidably installed inside the second movable groove 207. The limit rod 208 is fixedly connected to the outer surface of the mounting plate 201.

[0026] Power is transmitted to the connecting plate 305. Since the connecting plate 305 and the rotating wheel 202 are rigidly connected by the guide rod 203, and the limiting rod 208 inside the moving seat 204 strictly restricts its movement trajectory, the entire rolling assembly 2 can achieve high-precision vertical reciprocating motion.

[0027] A connecting plate 301 is fixedly connected to the outer surface of the mounting plate 201. A second servo motor 302 is fixedly connected to the top of the connecting plate 301. A worm gear 303 is fixedly connected to the output end of the second servo motor 302 through the connecting plate 301.

[0028] The mounting plate 201 is rotatably connected to a connecting plate 305, and a guide rod 203 is fixedly connected to one side of the outer surface of the connecting plate 305.

[0029] A worm gear 304 is fixedly connected to the outer surface of the connecting disc 305 away from the guide rod 203, and the worm gear 304 meshes with the worm 303.

[0030] The implementation principle of the cotton towel thickness uniformity adjustment device in this embodiment is as follows: After the fiber raw materials such as wood pulp and polyester are formed into a continuous wet paper web through the papermaking process, they are first laid on the surface of the conveyor belt 105 carried by the conveyor assembly 1. At this time, the first servo motor 109 is started, and its output end directly drives the transmission roller 102 to rotate, and synchronously drives the transport roller 103 to operate through the transmission chain 104, thereby forming a stable linear conveying power. This dual-roller linkage design not only ensures the tension balance of the wet paper web during the transmission process, but also avoids wrinkles or deviations caused by speed fluctuations. As the wet paper web gradually enters the crushing area, the second servo motor 302... The machine begins operation by transmitting power to the connecting disc 305 through the precise meshing of the worm gear 303 and worm wheel 304. Since the connecting disc 305 and the rotating wheel 202 are rigidly connected by the guide rod 203, and the limiting rod 208 inside the moving seat 204 strictly restricts its movement trajectory, the entire rolling assembly 2 can achieve high-precision vertical reciprocating motion. During this process, the rolling plate 206 applies uniform pressure to the wet paper, and excess water is squeezed out through the mesh of the conveyor belt 105 and falls into the collection rack 106 below. Under the guiding action of the inclined plate 107, the released water flows into the drain hole 108 along the preset path, finally completing the solid-liquid separation process.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
