Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and more specifically, to a web-laying machine for nonwoven fabric production. Background Technology

[0002] A web laying machine is a type of textile machinery mainly used to lay fiber webs into fiber layers of a certain thickness and width, providing a uniform fiber distribution for subsequent processing. However, existing web laying machines have difficulty pressing and compacting the fiber webs in a single layer during the web laying process. Instead, they often press and compact multiple layers of fiber webs uniformly after laying, which can easily lead to fiber web misalignment during the compaction process, resulting in uneven thickness of the laid fiber layers and affecting the subsequent use of the fiber layers.

[0003] Based on this, a web-laying machine for nonwoven fabric production is proposed. Summary of the Invention

[0004] The main objective of this invention is to provide a nonwoven fabric production web laying machine to overcome the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a nonwoven fabric production web laying machine, including a support frame. Guide plates are fixedly installed at the middle of the adjacent sides of the outer surfaces of the support frame. Guide teeth are fixedly provided on the upper surface of each guide plate. Sliding frames are movably fitted onto the outer surfaces of the guide plates. A fixed seat is fixedly provided at the middle of the front end of the outer surface of one of the sliding frames. Symmetrically arranged traction rollers are movably installed at the middle of the adjacent sides of the outer surfaces of the sliding frames.

[0006] Another sliding frame has a guide frame fixedly installed at the rear end of its lower surface. An adjusting screw is movably installed in the middle of the inner top surface of the guide frame via a bearing. A sliding block is spirally fitted on the outer surface of the adjusting screw.

The middle of the front end of the outer surface of the sliding block is convex and extends outward through the guide groove. An adjusting plate is movably fitted on the outer surface of the convex portion of the sliding block. Squeeze rollers are movably installed on both sides of the middle of the front end of the outer surface of the adjusting plate.

[0007] A positioning pin is fixedly provided on one side of the rear end of the outer surface of the adjusting plate. An electric push rod is fixedly installed on the lower part of one side of the outer surface of the sliding block. A control lever is movably installed on the output end of the electric push rod through a bearing. A movable buckle is fixedly provided on the other end of the control lever. The movable buckle is movably sleeved on the outer surface of the positioning pin. A third motor is fixedly installed on the upper surface of the guide frame. The output end of the third motor is fixedly connected to the adjusting screw.

[0008] As a further improvement of this utility model, a first conveying component is fixedly installed on the upper part of the outer surfaces of the support frame that are close to each other, and a second conveying component is fixedly installed on the lower part of the outer surfaces of the support frame that are close to each other. The first conveying component and the second conveying component are arranged in a cross shape.

[0009] As a further improvement of this utility model, both the first conveying assembly and the second conveying assembly include two sets of symmetrically arranged guide rollers. A conveyor belt is fitted onto the outer surface of the guide rollers. A motor is provided at the end of one of the guide rollers, and the motor is fixedly connected to the support frame.

[0010] As a further improvement of this utility model, a first motor is fixedly installed in the middle of the upper surface of the fixed base, and traction gears are movably installed above the two sets of sliding frames.

[0011] As a further improvement of this utility model, a second motor is fixedly installed on one side of the middle of the lower surface of the fixed base, and transmission gears are movably installed on both sides of the middle of the lower surface of the two sets of sliding frames. The transmission gears in the same set are arranged in a meshing manner, and the output end of the second motor is connected to the front end of the outer surface of one of the transmission gears.

[0012] As a further improvement of this utility model, a connecting rod is fixedly installed on the middle of the side of the outer surfaces of the two sets of transmission gears and traction gears, and a transmission belt is sleeved on both ends of the connecting rod of the transmission gear and the outer surfaces of both ends of the traction roller.

[0013] The beneficial effects of this utility model are:

[0014] This invention can press and compact single-layer fiber webs during the fiber web laying process, thereby ensuring the stability of the fiber web stacking and avoiding the displacement of single-layer fiber webs caused by uniform pressing and compaction of multiple layers of fiber webs after the fiber web is laid.

[0027] Please see Figures 1-6 As shown, a nonwoven fabric production web laying machine includes a support frame 1. A first conveying assembly 101 is fixedly installed on the upper part of the outer surfaces of the support frame 1 on the side closest to each other. A second conveying assembly 102 is fixedly installed on the lower part of the outer surfaces of the support frame 1 on the side closest to each other. The first conveying assembly 101 and the second conveying assembly 102 are arranged in a cross shape. Both the first conveying assembly 101 and the second conveying assembly 102 include two sets of symmetrically arranged guide rollers. A conveyor belt is sleeved on the outer surface of the guide rollers. A motor is provided at the end of one of the guide rollers. The motor is fixedly connected to the support frame 1.

[0028] It should be noted that the fiber web is conveyed by the first conveying component 101, and the conveyed fiber web is laid up on the second conveying component 102. After the laying up is completed, it is conveyed to the subsequent equipment for processing.

[0029] Guide plates 2 are fixedly installed on the middle of the side of the outer surface of the support frame 1. Guide teeth 201 are fixedly provided on the upper surface of the guide plates 2. Sliding frames 202 are movably installed on the outer surface of the guide plates 2. A fixed seat 203 is fixedly provided at the middle of the front end of the outer surface of one of the sliding frames 202. Traction rollers 204 are symmetrically installed on the middle of the side of the outer surface of the sliding frames 202.

[0030] A first motor 3 is fixedly installed in the middle of the upper surface of the fixed base 203. Traction gears 301 are movably installed above the two sets of sliding frames 202. The traction gears 301 and guide gears 201 are meshed with each other. The output end of the first motor 3 is connected to the front end of the outer surface of one set of traction gears 301. A second motor 4 is fixedly installed on one side of the middle of the lower surface of the fixed base 203. Transmission gears 401 are movably installed on both sides of the middle of the lower surface of the two sets of sliding frames 202. The transmission gears 401 in the same group are meshed with each other. The output end of the second motor 4 is connected to the front end of the outer surface of one of the transmission gears 401.

[0031] A connecting rod 5 is fixedly installed on the middle of the side of the outer surfaces of the two sets of transmission gears 401 and the traction gear 301. The two ends of the transmission gear 401 and the two ends of the traction roller 204 are fitted with a transmission belt 402.

[0032] It should be noted that by starting the first motor 3, the traction gear 301 can be controlled to rotate in both directions. Since the traction gear 301 and the guide gear 201 are meshed together, the sliding frame 202 can be moved laterally and reciprocally along the guide plate 2 by controlling the traction gear 301 to rotate in both directions using the first motor 3.

[0033] By starting the second motor 4, the transmission gear 401 can be controlled to rotate counterclockwise. Utilizing the meshing of the same group of transmission gears 401, the two transmission gears 401 in the same group will rotate in the same direction under the control of the second motor 4. At this time, the rotation of the transmission gear 401 will be transmitted to the traction roller 204 through the transmission belt 402, thereby synchronously driving the traction roller 204 to rotate in the same direction.

[0034] By passing the end of the fiber web through the traction roller 204, the fiber web can be continuously extracted under the action of the traction roller 204. While the sliding frame 202 moves laterally along the guide plate 2, the fiber web is driven to move laterally back and forth. During the back and forth movement, the fiber web is continuously extracted to complete the laying.

[0035] Another sliding frame 202 has a guide frame 6 fixedly installed at the rear end of its lower surface. An adjusting screw 601 is movably installed in the middle of the inner top surface of the guide frame 6 via a bearing. A sliding block 602 is spirally fitted on the outer surface of the adjusting screw 601. A guide groove 603 is opened through the middle of the front end of the outer surface of the guide frame 6. The middle of the front end of the outer surface of the sliding block 602 is convex and extends outward through the guide groove 603. An adjusting plate 8 is movably fitted on the outer surface of the convex part of the sliding block 602. Squeeze rollers 801 are movably installed on both sides of the middle of the front end of the outer surface of the adjusting plate 8.

[0036] A positioning pin 802 is fixedly installed on one side of the rear end of the outer surface of the adjusting plate 8. An electric push rod 9 is fixedly installed on the lower part of one side of the outer surface of the sliding block 602. A control lever 901 is movably installed on the output end of the electric push rod 9 via a bearing. A movable buckle 902 is fixedly installed on the other end of the control lever 901. The movable buckle 902 is movably sleeved on the outer surface of the positioning pin 802. A third motor 7 is fixedly installed on the upper surface of the guide frame 6. The output end of the third motor 7 is fixedly connected to the adjusting screw 601.

[0037] It should be noted that the adjustment screw 601 is controlled to rotate clockwise and counterclockwise by the third motor 7. The rotation of the adjustment screw 601 controls the sliding block 602 to move up and down along the guide groove 603. During the up and down movement, the adjustment plate 8 can be driven to move up and down simultaneously, thereby adjusting the position of the adjustment plate 8 as the fiber web is laid out.

[0038] By activating the electric push rod 9 to extend and retract, the angle can be adjusted by controlling the adjustment plate 8 with the cooperation of the control lever 901 and the movable buckle 902. When the electric push rod 9 is in the extended state, it can drive the part of the adjustment plate 8 connected to the control lever 901 to be in the raised state. When the electric push rod 9 is in the retracted state, it can drive the part of the adjustment plate 8 connected to the control lever 901 to be in the lowered state.

[0039] The angle adjustment of the adjusting plate 8 can control the extrusion roller 801 to be in a misaligned state. Since the guide frame 6 is fixedly connected to the sliding frame 202, the guide frame 6 will move synchronously during the transverse reciprocating movement of the sliding frame 202. During the movement, the extrusion roller 801 located at the lower side can roll and extrude the lower layer of fiber web during the fiber web laying process, while the extrusion roller 801 located at the upper side can roll and extrude the upper layer of fiber web, thereby realizing the sequential compaction of the single layer of fiber web.

[0040] When the extrusion roller 801 moves laterally and reciprocally with the sliding frame 202 to the end of the single-layer fiber web, the extrusion roller 801 located at the lower position can detach from the fiber web because the fiber web is laid out in a Z-shape. At this time, the control adjustment plate 8 adjusts the angle to move the extrusion roller 801 at the lower position to the upper position, so that the subsequent fiber web can be extruded and compacted. At the same time, the extrusion roller 801 located at the upper position can be adjusted to the lower position, and after compacting the subsequent fiber web, it moves to the end of the fiber web and detaches from the fiber web. At this time, it can be adjusted to the upper position again, so as to perform reciprocating operation to complete the laying and compaction of the fiber web.

[0041] In use, the fiber web can first be covered onto the first conveying component 101, which then conveys the fiber web. At this time, the second motor 4 is started to control the transmission gear 401 to rotate counterclockwise. Utilizing the meshing of the same group of transmission gears 401, the two transmission gears 401 in the same group will rotate in the same direction under the control of the second motor 4. The rotation of the transmission gears 401 will be transmitted to the traction roller 204 through the transmission belt 402, thereby synchronously driving the traction roller 204 to rotate in the same direction. By passing the end of the fiber web through the traction roller 204, the fiber web can be continuously extracted under the action of the traction roller 204.

[0042] At this time, the first motor 3 can be started to control the traction gear 301 to rotate in both directions. Since the traction gear 301 and the guide gear 201 are meshed together, the first motor 3 can control the traction gear 301 to rotate in both directions, which can drive the sliding frame 202 to move laterally back and forth along the guide plate 2. In this case, the fiber web can be driven to move laterally back and forth. During the back and forth movement, the fiber web is continuously extracted to complete the Z-shaped layup.

[0043] When the fiber web continues to stack, the third motor 7 can be started to control the adjusting screw 601 to rotate clockwise, thereby controlling the sliding block 602 to rise along the guide groove 603, and simultaneously driving the adjusting plate 8 to rise.

[0044] At this time, the electric push rod 9 is activated to extend and retract. The angle can be adjusted by controlling the adjustment plate 8 with the cooperation of the control lever 901 and the movable buckle 902. When the electric push rod 9 is in the extended state, it can drive the part of the adjustment plate 8 connected to the control lever 901 to be in the raised state. When the electric push rod 9 is in the retracted state, it can drive the part of the adjustment plate 8 connected to the control lever 901 to be in the lowered state.

[0045] The angle adjustment of the adjusting plate 8 can control the extrusion roller 801 to be in a misaligned state. Since the guide frame 6 is fixedly connected to the sliding frame 202, the guide frame 6 will move synchronously during the transverse reciprocating movement of the sliding frame 202. During the movement, the extrusion roller 801 located on the lower side can roll and extrude the lower layer of fiber web during the fiber web laying process, while the extrusion roller 801 located on the upper side can roll and extrude the upper layer of fiber web, thereby realizing the sequential compaction of the single layer of fiber web.

[0046] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
