Description

Technical Field

[0001] The invention relates to a dehydrating device for non-woven fabric production, belonging to the technical field of non-woven fabric production. Background Art

[0002] Nonwoven fabrics are made from natural pure cotton fibers. After undergoing pre-processing, such as opening and loosening, the fibers are combed into a web using equipment such as carding machines, web laying machines, and drafting machines. The cotton fibers are then entangled and bonded together to form the nonwoven fabric. However, the finished nonwoven fabric often contains moisture, so to ensure effective subsequent drying, it is typically pre-dehydrated using a dehydration unit designed for nonwoven fabric production.

[0003] The current mainstream dewatering equipment for nonwoven fabric production consists of a machine frame, a built-in water collection module, an automatically rotating lower hard roller, and an upper soft roller positioned above it. The specific operation process is as follows: the nonwoven fabric is introduced into the gap between the upper and lower rollers. The synchronous rotation of the lower hard roller and the upper soft roller squeezes the nonwoven fabric in a line-contact manner. During this process, the moisture inside the nonwoven fabric is squeezed out and collected in the water collection module at the bottom of the machine frame, achieving the dehydration goal of reducing the moisture content.

[0004] However, existing devices have a significant technical bottleneck: because the contact surface between the upper and lower rollers and the nonwoven fabric is linearly distributed, and the rollers rotate continuously during operation, the single extrusion time is extremely short. This can lead to incomplete destruction of the water film between the nonwoven fibers, causing some water to migrate internally rather than be expelled. This ultimately results in a high rate of residual moisture, seriously affecting dehydration efficiency and product quality. Summary of the Invention

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0048] Example 1: Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, a dewatering device for non-woven fabric production is provided, comprising: a frame 1, a fixed portion of a lifting device is mounted on the middle portion of the upper end of the frame 1, and a movable portion of the lifting device passes through the frame 1 and is connected to a shell 2 located inside the frame 1, and the shell 2 is driven up and down by the lifting device. The lifting device can use a hydraulic cylinder 14, and then the fixed portions of four telescopic rods 13 located outside the lifting device are respectively mounted on the four corner positions of the upper end of the frame 1, and the movable portions of the four telescopic rods 13 all pass through the frame 1 and are connected to the upper end of the shell 2. The four telescopic rods 13 are used in conjunction to guide the movement of the shell 2;

[0049] A hard roller 4 movably arranged at the lower end of the shell 2 and extending into the shell 2 is rotatably connected to the frame 1, and the middle portion of the lower end of the conveyor belt 8 located in the shell 2 is fitted with the upper end of the hard roller 4, and the contact surface between the conveyor belt 8 and the hard roller 4 is arc-shaped. The conveyor belt 8 and the hard roller 4 are used in conjunction with each other to dehydrate the produced non-woven fabric, and then the fixed portion of the first driving device connected to the output shaft and the hard roller 4 is installed on the left end of the frame 1. The hard roller 4 is driven to rotate by the first driving device, and the first driving device can adopt a first motor 41;

[0050] A water collecting box 3, which is arranged at the lower end of the hard roller 4 and has a V-shaped cross-section with a wide upper part and a narrow lower part, is installed in the frame 1, and the hard roller 4 extends into the water collecting box 3. The waste water generated by the dehydration operation is collected through the water collecting box 3. The rotating roller 21 engaged with the rear wall of the inner part of the conveyor belt 8 is rotatably connected to the outer shell 2, and the auxiliary roller 22 engaged with the front wall of the inner part of the conveyor belt 8 is rotatably connected to the outer shell 2. The rotating roller 21 and the auxiliary roller 22 are used in conjunction with each other to drive the conveyor belt 8 to move. The fixed part of the second driving device connected with the output shaft and the rotating roller 21 is installed on the right end of the outer shell 2. The rotating roller 21 is driven to rotate by the second driving device. The second driving device can adopt a second motor 5.

[0051] The two guide rollers 11 located on the front and rear sides of the hard roller 4 are symmetrically rotated and connected to the inside of the frame 1. The two guide rollers 11 are used in conjunction to guide the non-woven fabric in and out of the shell 2, and the two edge limiting annular plates 12 located on the outside of the hard roller 4 and the bottom side of the shell 2 are symmetrically arranged on the outer ends of the guide rollers 11. The two edge limiting annular plates 12 are used in conjunction to limit the non-woven fabric in and out of the shell 2.

[0052] When in use, the produced non-woven fabric is first introduced into the frame 1, and the non-woven fabric is passed around the lower end of a guide roller 11, the upper end of the hard roller 4 and the lower end of another guide roller 11 in sequence, and then the non-woven fabric is led out of the frame 1, and then the non-woven fabric is introduced into the next process equipment and connected to the traction equipment, and then the hydraulic cylinder 14 is started to drive the shell 2 to move downward, and the hard roller 4 is inserted into the shell 2. At this time, the upper and lower ends of the non-woven fabric are respectively in contact with the conveyor belt 8 and the hard roller 4, and the contact surface of the conveyor belt 8, the non-woven fabric and the hard roller 4 is arc-shaped;

[0053] Then the non-woven fabric is pulled so that the non-woven fabric moves between the conveyor belt 8 and the hard roller 4, and the first motor 41 and the second motor 5 are started at the same time. The first motor 41 drives the hard roller 4 to rotate, and the second motor 5 drives the rotating roller 21 to rotate, and with the assistance of the auxiliary roller 22, drives the conveyor belt 8 to move, and makes the movement direction of the non-woven fabric and the movement direction of the lower part of the conveyor belt 8 the same as the rotation direction of the hard roller 4. At this time, the moving conveyor belt 8 and the rotating hard roller 4 will exert arc-shaped extrusion on the non-woven fabric, thereby dehydrating the non-woven fabric, and realizing an arc-shaped dehydration surface of the non-woven fabric, effectively reducing the probability of water migration and failure to be discharged during dehydration due to factors such as short extrusion contact time of the non-woven fabric, effectively reducing the moisture residual rate of the non-woven fabric, and effectively ensuring the dehydration effect and quality of the non-woven fabric.

[0054] Example 2: Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, a plurality of fixed rods 81 passing through the conveyor belt 8 are equidistantly arranged on the side ends of the conveyor belt 8. The fixed rods 81 provide a mounting carrier for the guide wheels 82 on the one hand, and on the other hand, increase the strength of the conveyor belt 8. The two guide wheels 82 located on the outside of the conveyor belt 8 are rotatably connected to the left and right ends of the fixed rods 81 respectively. The movement of the fixed rods 81 is guided by the guide wheels 82. The two limit plates 6 located on the left and right sides of the conveyor belt 8 are symmetrically arranged on the bottom end of the inner part of the shell 2. An arcuate surface is provided on the upper end of the limit plate 6, and a plurality of guide wheels 82 are rollingly connected to the outer surface of the arcuate surface. The limit plate 6 and the arcuate surface are used in conjunction with each other to guide the movement of the guide wheels 82.

[0055] Two functional guide plates 62 fixedly connected to the inner bottom end of the shell 2 and integrated with the limit plate 6 are respectively installed on the front and rear ends of the limit plate 6, and the two functional guide plates 62 with triangular cross sections are arranged opposite to each other, and the inclined surfaces of the functional guide plates 62 are tangentially connected to the arc surface, and the inclined outer surfaces of the functional guide plates 62 are rollingly connected to the guide wheel 82. The two functional guide plates 62 are used in conjunction with each other to guide the guide wheel 82 entering and exiting the arc surface, and the limiting plates 61 extending from the front and rear ends to the inclined outer surfaces of the two functional guide plates 62 are respectively arranged on the outer surface of the arc surface, and the limiting plate 61 located on the lower side of the fixed rod 81 is attached to the inner end of the guide wheel 82, and the guide wheel 82 moving on the arc surface is limited by the limiting plate 61;

[0056] A first arcuate groove 711 is provided on the lower end surface of the press box 7 located between the rotating roller 21 and the auxiliary roller 22 and inside the conveyor belt 8. The first arcuate groove 711 is in contact with the bottom end of the inner portion of the conveyor belt 8. The press box 7 and the first arcuate groove 711 cooperate to limit the dehydration area of ​​the conveyor belt 8. The transverse portions of two L-shaped plates 72 located inside the conveyor belt 8 are respectively installed on the left and right ends of the press box 7. The L-shaped plates 72 provide a mounting support for the mounting rod 73.

[0057] A second arc groove 721 is provided at the lower end of the vertical portion of the L-shaped plate 72, which is located directly above the arc surface, and the lower end of the second arc groove 721 is rollingly connected to the upper end of the guide wheel 82. The second arc groove 721 restricts the guide wheel 82 moving on the arc surface, and multiple mounting rods 73 connected to the inner wall of the outer shell 2 at the other end are equidistantly installed on the outward end of the L-shaped plate 72. Multiple mounting rods 73 are used in combination to connect the L-shaped plate 72 and the outer shell 2, and multiple conductive columns 71 extending to the lower end of the press box 7 are evenly installed on the bottom end of the inner part of the press box 7, and the lower end faces of the multiple conductive columns 71 coincide with the first arc groove 711. The multiple conductive columns 71 are used in combination to process the static electricity generated by friction on the conveyor belt 8.

[0058] When in use, the non-woven fabric is first passed around the lower end of a guide roller 11, the upper end of the hard roller 4 and the lower end of another guide roller 11 in sequence, and then the non-woven fabric is introduced into the next process equipment and connected to the traction equipment. Then, the hydraulic cylinder 14 is used to move the shell 2 downward and insert the hard roller 4 into the shell 2. At this time, the upper and lower ends of the non-woven fabric are respectively attached to the conveyor belt 8 and the hard roller 4, and the contact surface of the conveyor belt 8, the non-woven fabric and the hard roller 4 is arc-shaped. Then, the non-woven fabric is pulled, so that the non-woven fabric moves between the conveyor belt 8 and the hard roller 4.

[0059] Then, the first motor 41 is used to drive the hard roller 4 to rotate, and the second motor 5 is used to drive the rotating roller 21 to rotate, and with the assistance of the auxiliary roller 22, the conveyor belt 8 is driven to move, thereby causing the multiple fixed rods 81 to move along with the movement of the conveyor belt 8, thereby causing the multiple guide wheels 82 to move. When the guide wheel 82 moves to the inclined surface of a functional guide plate 62, the guide wheel 82 rolls along the inclined surface of the functional guide plate 62, thereby causing the corresponding fixed rod 81 to gradually move obliquely upward, thereby causing the corresponding local area on the conveyor belt 8 to gradually move obliquely upward;

[0060] Then, the guide wheel 82 enters the arc surface under the guidance of the inclined surface of the functional guide plate 62, and makes the guide wheel 82 roll on the arc surface, so that the fixed rod 81 moves along the arc path, and then makes the conveyor belt 8 that moves to the dewatering area move along the arc path, and then the guide wheel 82 moves from the arc surface to the inclined surface of another functional guide plate 62 and continues to roll, so that the corresponding fixed rod 81 gradually moves obliquely downward, and thus the corresponding area on the conveyor belt 8 gradually moves obliquely downward;

[0061] The conveyor belt 8 is provided with a limited guide for the extrusion part, which effectively reduces the probability of excessive extrusion of the center line of the extrusion part of the conveyor belt 8 due to the arc motion of the conveyor belt 8, and effectively reduces the probability of indentation of the non-woven fabric during the dehydration operation. The inclined surface of the functional guide plate 62 guides the guide wheel 82 in and out of the arc surface, so that the corresponding local area in the conveyor belt 8 performs a gradual movement, effectively reducing the probability of stretching deformation of the conveyor belt 8 when entering and exiting the dehydration position, effectively reducing the probability of wrinkles on the non-woven fabric entering and exiting the dehydration position, and effectively ensuring the dehydration effect and quality of the non-woven fabric.

[0062] At the same time, when the guide wheel 82 moves on the inclined surface and the arc surface of the auxiliary guide plate, the two limiting plates 61 will limit the two rolling guide wheels 82 located at both ends of the fixed rod 81, thereby performing bidirectional limiting on the corresponding fixed rod 81, thereby achieving bidirectional limiting on the conveyor belt 8 entering the dehydration position, effectively reducing the probability of the conveyor belt 8 being deviated to the left or right at the dehydration position, effectively reducing the probability of the non-woven fabric being deviated to the left or right during dehydration, and effectively ensuring the dehydration effect and quality of the non-woven fabric;

[0063] The second arc groove 721 on the L-shaped plate 72 will limit the position of the guide wheel 82 rolling on the arc surface, thereby restricting the guide wheel 82 rolling on the arc surface, effectively reducing the probability of the guide wheel 82 and the fixed rod 81 jumping, etc., and effectively reducing the probability of the non-woven fabric being not squeezed at the edge of the conveyor belt 8 in the dehydration position, thereby effectively ensuring the dehydration effect and quality of the non-woven fabric;

[0064] When relative movement occurs between the conveyor belt 8 and the first arc-shaped groove 711, the static electricity generated by friction on the conveyor belt 8 is guided into the water in the press box 7 by multiple conductive columns 71, thereby removing static electricity from the conveyor belt 8, effectively reducing the probability of fuzzing on the upper surface of the non-woven fabric due to static electricity, and effectively ensuring the dehydration effect and quality of the non-woven fabric. At this time, the movement direction of the non-woven fabric and the movement direction of the lower part of the conveyor belt 8 are in the same state as the rotation direction of the hard roller 4. At this time, the moving conveyor belt 8 and the rotating hard roller 4 will squeeze the non-woven fabric, thereby dehydrating the non-woven fabric.

[0065] Example 3: Figures 11-13 As shown, a fixed plate 32, which is arranged obliquely with the left side lower and the right side higher and is located outside the hard roller 4, is installed in the water collecting tank 3. The fixed plate 32 provides a mounting carrier for components such as the wiper 31. The wiper 31 attached to the outer end of the hard roller 4 is attached to the upper end of the fixed plate 32. The outer surface of the hard roller 4 is wiped by the wiper 31. Then, an auxiliary plate 37 located between the fixed plate 32 and the hard roller 4 is installed on the lower end of the wiper 31. The auxiliary plate 37 provides a mounting carrier for the connecting rod 36.

[0066] A plurality of mounting holes 33 are formed outwardly on the right end surface of the fixing plate 32 in a recessed manner. The mounting holes 33, the guide plate 35 and other components provide mounting space, and a plurality of connecting rods 36 are equidistantly mounted on the outer end of the auxiliary plate 37. The connecting rods 36 provide a mounting carrier for the guide plate 35, and the plurality of guide plates 35 are respectively slidably connected to the plurality of mounting holes 33, and the plurality of connecting rods 36 extend into the plurality of mounting holes 33 and are respectively connected to the plurality of guide plates 35. The guide plates 35 are used in conjunction with the mounting holes 33 to guide the movement of the wiper blade 31, and then the other ends of the plurality of elastic members 34 respectively connected to the bottom ends of the plurality of mounting holes 33 are respectively connected to the other ends of the plurality of guide plates 35. The elastic members 34 are used to apply thrust to the guide plates 35, and the elastic members 34 can be springs.

[0067] When in use, the non-woven fabric is first passed around the lower end of a guide roller 11, the upper end of the hard roller 4 and the lower end of another guide roller 11 in sequence, and then the non-woven fabric is introduced into the next process equipment and connected to the traction equipment. Then, the hydraulic cylinder 14 is used to move the shell 2 downward and insert the hard roller 4 into the shell 2. At this time, the upper and lower ends of the non-woven fabric are respectively attached to the conveyor belt 8 and the hard roller 4, and the contact surface of the conveyor belt 8, the non-woven fabric and the hard roller 4 is arc-shaped. Then, the non-woven fabric is pulled, so that the non-woven fabric moves between the conveyor belt 8 and the hard roller 4.

[0068] Then, the first motor 41 is used to drive the hard roller 4 to rotate, and the second motor 5 is used to drive the rotating roller 21 to rotate. With the assistance of the auxiliary roller 22, the conveyor belt 8 is driven to move, and then the multiple fixed rods 81 move along with the movement of the conveyor belt 8, thereby causing the multiple guide wheels 82 to move. At the same time, with the assistance of the inclined surfaces and curved surfaces of the two functional guide plates 62, the extrusion part of the conveyor belt 8 is limited and guided, and the first curved groove 711 at the lower end of the pressing box 7 presses the conveyor belt 8.

[0069] The moving direction of the non-woven fabric, the moving direction of the lower part of the conveyor belt 8 and the rotating direction of the hard roller 4 are in the same state. At this time, the moving conveyor belt 8 and the rotating hard roller 4 will squeeze the non-woven fabric, thereby dehydrating the non-woven fabric, and the waste water generated by dehydration will fall along the outer surface of the hard roller 4 and enter the water collecting tank 3, thereby collecting the waste water. At the same time, the scraper 31 and the hard roller 4 move relative to each other, so that the scraper 31 is used to remove water from the outer surface of the hard roller 4, effectively reducing the probability of water removed from the non-woven fabric re-attaching to the non-woven fabric;

[0070] When the wiper 31 is worn, the elastic member 34 is originally in a compressed state, so the elastic member 34 itself has elastic force, and under the action of the elastic force, it applies an upward thrust to the guide plate 35, thereby causing the connecting rod 36 and the auxiliary plate 37 to move upward, thereby causing the wiper 31 to move upward, so that the wiper 31 and the hard roller 4 are always in close contact, effectively reducing the probability of a gap between the wiper 31 and the hard roller 4 due to factors such as wear, effectively ensuring the dehydration effect and quality of the non-woven fabric, and improving the service life of the wiper 31.

[0071] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
