Novel transmission device for feeding roller of vibrating cotton box and vibrating cotton box

Abstract

The application provides a new type of feeding roller transmission device for a vibrating cotton box and the vibrating cotton box. Two screw rods drive two feeding rollers to make reciprocating rotary motion through a driving mechanism. The two ends of one feeding roller are rotatably connected with two lever frames, and the two lever frames are connected through a lever shaft, so that the synchronous motion of the two lever frames is ensured. The two ends of the other feeding roller are rotatably connected with two side wall plates. The lever frames are connected with the wall plates through elastic return members, and the elastic return members provide elastic tension force, so that the distance between the two feeding rollers can be adjusted automatically during the operation of the equipment. Through the above arrangement, compared with the traditional two feeding rollers with a fixed distance, the new type of feeding roller transmission device changes the continuous rotary motion of the feeding roller into reciprocating rotary motion, and the distance between the two feeding rollers can be automatically adjusted without stopping the equipment.

Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric machinery technology, and specifically relates to a novel transmission device for a feeding roller in a vibrating cotton box and a vibrating cotton box. Background Technology

[0002] The cotton feeding box for nonwoven fabrics is an important part of the dry web forming nonwoven fabric production line. It is the connecting device between the opening and cleaning equipment and the web forming equipment. Among them, the vibrating cotton box is a type of cotton feeding box. Its working principle is to use vibration to even out the cotton. The loose and insufficiently mixed fibers peeled off from the top peeling roller are made more uniform and compact by the reciprocating vibration of the vibrating plate with mesh, so as to achieve continuous, uniform and stable feeding to the web forming equipment.

[0003] In existing technologies, the feeding roller drive of a vibrating cotton box typically uses chain or gear transmission. A pair of feeding rollers rotate in opposite directions to feed fibers into the lower cotton box. However, the distance between the two feeding rollers in a traditional system cannot be adjusted during operation. When encountering large fiber blocks, they cannot pass between the two feeding rollers, causing them to jam and stop operating. This can even damage the geared motor that drives the feeding rollers.

[0004] Furthermore, the operating speed of the feed roller cannot be adjusted without replacing the chain or gears; the corresponding chain or gears can only be replaced while the machine is stopped, thereby changing the operating speed of the feed roller.

[0005] The use of the aforementioned transmission device results in high labor intensity, low working efficiency of nonwoven machinery, low nonwoven output, and high equipment maintenance costs.

[0006] Therefore, how to overcome the above-mentioned technical defects is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a novel transmission device for the feeding rollers of a vibrating cotton box and a vibrating cotton box, which can adjust the distance between the two feeding rollers without stopping the machine.

[0008] To solve the above-mentioned technical problems, the present invention provides a novel transmission device for a feeding roller for a vibrating cotton box, comprising a drive mechanism, two lever frames, a lever shaft, two elastic reset members, and two screws;

[0009] The fixed end of the drive mechanism is installed on the box body of the vibration cotton box;

[0010] One end of each of the two lever frames is rotatably mounted on the two side wall panels of the housing. The two ends of the lever shaft are connected to one end of each of the two lever frames. The other ends of each of the two lever frames are connected to the wall panel on the corresponding mounting side through an elastic reset member. Each lever frame and the two side wall panels are provided with a seated bearing for connecting to the end of the feed roller.

[0011] One end of each of the two screws is mounted on the output shaft of the drive mechanism via a suspended bearing housing, and the other end of each of the two screws is mounted on the ends of two feed rollers located on the same side of the drive mechanism via a suspended bearing housing.

[0012] Optionally, the above-mentioned novel transmission device for the feeding roller of the vibrating cotton box also includes a crank-slider mechanism, which includes a crank, a slider shaft, a stop plate and an adjusting bolt.

[0013] One end of the crank is connected to the output shaft of the drive mechanism, and the other end of the crank is provided with a slide groove arranged in a direction perpendicular to the crank axis. A stop plate is provided at one end of the slide groove. The adjusting bolt passes through the stop plate and is threadedly engaged with the stop plate. The head of the adjusting bolt is located on the side of the stop plate away from the slide groove, and the threaded part of the adjusting bolt is located in the slide groove and is threadedly connected to one end of the slider shaft. Rotating the adjusting bolt causes the slider shaft to slide in the length direction of the slide groove.

[0014] One end of each of the two screws is mounted on the other end of the slider shaft via a suspended bearing seat, and the other ends of the two screws are mounted on the ends of two feed rollers located on the same side of the crank-slider mechanism via suspended bearing seats.

[0015] Optionally, in the above-mentioned novel transmission device for feeding rollers in a vibrating cotton box, the elastic reset component includes a tension spring and a hook. One end of the tension spring is connected to the lever frame and the other end is detachably connected to one end of the hook. The other end of the hook passes through the wall panel and is provided with an external thread, so that the hook can be locked to the wall panel by an adjusting nut.

[0016] Optionally, in the above-mentioned novel transmission device for feeding rollers in a vibrating cotton box, a first limiting member and a second limiting member are provided on both sides of the wall panels. The first limiting member and the second limiting member are respectively provided on both sides of the lever frame to limit the swing angle of the other end of the lever frame.

[0017] Optionally, in the above-mentioned novel transmission device for the feeding roller of the vibrating cotton box, both the first limiting member and the second limiting member include a mounting plate disposed on the wall panel and a limiting screw threadedly connected to the mounting plate.

[0018] Optionally, the above-mentioned novel transmission device for feeding rollers in a vibrating cotton box further includes two clutches, which are respectively located at the ends of two feeding rollers on the same side of the drive mechanism, and the hanging bearing seats on each feeding roller are connected to the clutches.

[0019] Optionally, in the above-mentioned novel transmission device for the feeding roller of the vibrating cotton box, both ends of each clutch are fixed to the ends of the feeding roller by a retaining ring.

[0020] Optionally, in the above-mentioned novel transmission device for the feeding roller of the vibrating cotton box, the end of the screw is connected to the suspended bearing seat through a spacer.

[0021] The present invention also provides a vibrating cotton box, including a box body, a pair of feed rollers, and a novel transmission device for the feed rollers of the vibrating cotton box as described above.

[0022] Optionally, the vibrating cotton box also includes two cotton baffles, which are respectively disposed on both sides of the two feeding rollers away from the feeding port.

[0023] Optionally, the vibrating cotton box described above also includes a soft curtain assembly, which is disposed between the feed roller and the cotton baffle plate near the feed roller.

[0024] Optionally, in the above-mentioned vibrating cotton box, the soft curtain assembly includes a clamping plate and a soft curtain, the clamping plate being fixed to the cotton blocking plate or the wall panel, and the clamping plate being used to hold the soft curtain.

[0025] This invention provides a novel transmission device for a feeding roller in a vibrating cotton box, the advantages of which are:

[0026] The system utilizes a drive mechanism that uses two screws to drive two feed rollers in a reciprocating rotation. One feed roller has two rotatable supports mounted on two lever frames, with each side of the other feed roller fixed to the lever frames via bearing seats. The two lever frames are connected by lever shafts to ensure synchronous movement. The other feed roller is also fixed to the side panels of the housing via bearing seats, ensuring that the distance between the two feed rollers remains consistent in the width direction during the oscillation of the first feed roller. The lever frames are connected to the side panels via elastic return elements, which provide elastic tension. The distance between the two feed rollers can be automatically adjusted during operation. When a large fiber block passes between the two feed rollers, the fiber block's own force increases the distance between them. Under the action of the elastic return elements, after the large fiber block passes the gap between the two feed rollers, the feed rollers on the lever frames return to their previous working positions, improving the adaptability of the vibrating cotton box to raw materials.

[0027] With the above settings, compared to the traditional two feed rollers with non-adjustable spacing, this invention provides a new type of transmission device for the feed rollers, which changes the feed rollers from continuous rotational motion to reciprocating rotational motion, and the spacing between the two feed rollers can be automatically adjusted without stopping the equipment.

[0028] The present invention also provides a vibrating cotton box having the above-mentioned novel transmission device for the feeding roller of the vibrating cotton box, which has the same beneficial effects, and will not be described in detail here. Attached Figure Description

Detailed Implementation

[0042] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] The core of this invention is to provide a novel transmission device for the feeding rollers of a vibrating cotton box and a vibrating cotton box, which can adjust the distance between the two feeding rollers without stopping the machine.

[0044] To enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] For details, please refer to Figures 1-6 The present invention provides a novel transmission device for a feeding roller for a vibrating cotton box, comprising a drive mechanism 410, two lever frames, a lever shaft 530, two elastic reset members, and two screws.

[0046] The fixed end of the drive mechanism 410 is mounted on the housing of the vibrating cotton box, serving as the power source for the rotation of the feed roller. Specifically, the bracket 111 is mounted on one side wall of the housing, and the fixed end of the drive mechanism 410 is mounted on the bracket 111 to provide a mounting position for the drive mechanism 410. The drive mechanism 410 can be a geared motor.

[0047] One end of each of the two lever frames is rotatably mounted on one side wall panel of the housing. Both ends of the lever shaft 530 are connected to one end of each of the two lever frames. The other ends of each lever frame are connected to the corresponding mounting side wall panel via elastic reset members. Each lever frame and both side wall panels are equipped with a seated bearing 561 for connecting to the end of the feed roller. This allows one feed roller to be fixedly connected to the lever frames on both sides via seated bearings 561, and the other feed roller to be fixedly connected to the side wall panels on both sides via seated bearings 561.

[0048] Specifically, both ends of the lever shaft 530 are rotatably connected to the two side wall plates via shaft seats 531, and both ends of the lever shaft 530 are also connected to the lever frame. One end of the lever frame is rotatably mounted on the wall plate, and the other end is movably connected to the wall plate via an elastic reset member, thereby allowing the other end of the lever frame to rotate around its first end within a certain angle. During operation, the swing angle of the two lever frames can be adjusted so that their supporting planes are in the same plane.

[0049] One end of each of the two screws is mounted on the output shaft of the drive mechanism 410 via a suspended bearing housing, and the other end of each screw is mounted on the ends of two feed rollers located on the same side of the drive mechanism 410 via suspended bearing housings. The suspended bearing housings can accommodate installation scenarios where the shaft is parallel to the mounting surface.

[0050] The present invention provides a novel transmission device for a vibrating cotton box feed roller. A drive mechanism 410 drives two feed rollers to reciprocate through two screws. One feed roller has two rotatable sides mounted on two lever frames. The two sides of one feed roller are fixed to the lever frames on either side by bearings 561. The two lever frames are connected to each other via lever shafts 530, ensuring synchronous movement. The other feed roller is fixed to the side panels of the box body via bearings 561, ensuring that the distance between the two feed rollers remains consistent in the width direction during the oscillation of one feed roller. The lever frames are connected to the side panels via elastic return members, which provide elastic tension. The distance between the two feed rollers can be automatically adjusted during equipment operation. When a large fiber block passes between the two feed rollers, the fiber block itself increases the distance between the two feed rollers. Under the action of the elastic reset element, after the large fiber block passes the distance between the two feed rollers, the feed rollers set on the lever frame return to their previous working positions, which improves the adaptability of the vibrating cotton box to the raw materials of the product.

[0051] With the above settings, compared to the traditional two feed rollers with non-adjustable spacing, this invention provides a new type of transmission device for the feed rollers, which changes the feed rollers from continuous rotational motion to reciprocating rotational motion, and the spacing between the two feed rollers can be automatically adjusted without stopping the equipment.

[0052] Based on the above specific embodiments, this solution also includes a crank-slider mechanism 420, which includes a crank 421, a slider shaft 422, a stop plate 423, and an adjusting bolt 424.

[0053] One end of the crank 421 is connected to the output shaft of the drive mechanism 410. The other end of the crank 421 is provided with a slide groove arranged in a direction perpendicular to the axis of the crank 421. One end of the slide groove is provided with a stop plate 423. An adjusting bolt 424 passes through the stop plate 423 and is threadedly engaged with the stop plate 423. The head of the adjusting bolt 424 is located on the side of the stop plate 423 away from the slide groove. The threaded part of the adjusting bolt 424 is located in the slide groove and is threadedly connected to one end of the slider shaft 422. Rotating the adjusting bolt 424 causes the slider shaft 422 to slide in the length direction of the slide groove.

[0054] The slider shaft 422 is mounted on the crank 421 and can slide freely on the crank 421. At the same time, a stop plate 423 is provided on one side of the crank 421. The adjusting bolt 424 is connected and fixed to the slider shaft 422 through the stop plate 423. Rotating the adjusting bolt 424 can drive the slider shaft 422 to make linear motion on the crank 421, thereby adjusting the center distance between the slider shaft 422 and the output shaft of the drive mechanism 410.

[0055] In actual operation, rotating the adjusting bolt 424 clockwise will move the slider shaft 422 toward the output shaft of the drive mechanism 410, thereby reducing the center distance between the slider shaft 422 and the output shaft of the drive mechanism 410. Rotating the adjusting bolt 424 counterclockwise will move the slider shaft 422 away from the output shaft of the drive mechanism 410, thereby increasing the center distance between the slider shaft 422 and the output shaft of the drive mechanism 410.

[0056] Specifically, the center distance between the slider shaft 422 and the output shaft of the drive mechanism 410 is preferably set to 15mm-60mm.

[0057] One end of each of the two screws is mounted on the other end of the slider shaft 422 via a hanging bearing seat, and the other ends of the two screws are mounted on the ends of the two feed rollers located on the same side of the crank-slider mechanism 420 via a hanging bearing seat.

[0058] With the above structure, the motion process of the feed roller is as follows: the drive mechanism 410 drives the crank 421 to rotate, which in turn drives the slider shaft 422 to rotate, and through the two screws, drives the two feed rollers to reciprocate.

[0059] By setting up the crank-slider mechanism 420, the operating speed of the two feed rollers can be adjusted simply by changing the center distance between the slider shaft 422 and the output shaft of the geared motor without replacing the relevant parts, effectively reducing the maintenance cost of the equipment.

[0060] In a specific embodiment, the elastic reset component includes a tension spring 541 and a hook 542. One end of the tension spring 541 is connected to the lever frame and the other end is detachably connected to one end of the hook 542. The other end of the hook 542 passes through the wall panel and is provided with an external thread so that the hook 542 is locked to the wall panel by the adjusting nut 543.

[0061] The lever frame is connected to the tension spring 541 and the hook 542. The hook 542 is connected to the wall panel through the adjusting nut 543. The two lever frames can swing around the lever shaft 530 as the rotation center. By rotating the adjusting nut 543, the relative position of the hook 542 can be adjusted, thereby adjusting the tension of the tension spring 541.

[0062] In a specific embodiment, a first limiting member and a second limiting member are provided on both side wall panels. The first limiting member and the second limiting member are respectively located on both sides of the lever frame to limit the swing angle of the other end of the lever frame. The positions of the first limiting member and the second limiting member can be adjusted adaptively according to actual needs.

[0063] Furthermore, both the first and second limiting components include a mounting plate disposed on the wall panel and a limiting screw threadedly connected to the mounting plate.

[0064] Specifically, such as Figure 4 As shown, each of the two side wall panels is equipped with a first limiting screw 551 and a second limiting screw 552. By rotating the first limiting screw 551 and / or the second limiting screw 552, the distance between the two feed rollers can be increased or decreased, thereby limiting and adjusting the swing amplitude of the two lever frames.

[0065] The limit screw is moved relative to the mounting plate by rotating it. The end of the limit screw restricts the movement of the lever frame. The swing angle range of the lever frame can be adjusted using this method. Of course, the first and second limit components can also adopt other structural forms, designed as limit structures fixed to the wall panel or as limit structures movable on the wall panel, which are not further limited here.

[0066] This solution also includes two clutches 562, which are respectively located at the ends of two feed rollers on the same side of the drive mechanism 410, and the hanging bearing seats on each feed roller are connected to the clutches 562.

[0067] Each of the two feed rollers is equipped with a clutch 562 at one end. When the cotton accumulation between the two feed rollers is severe and the two feed rollers become stuck and cannot continue to operate, the clutch 562 will prevent the load on the drive mechanism 410 from increasing, and the drive mechanism 410 can continue to operate normally, preventing damage to the drive mechanism 410 and reducing the operating and maintenance costs of the equipment.

[0068] To further secure and limit the clutches 562, both ends of each clutch 562 are fixed to the ends of the feed rollers by retaining rings 563.

[0069] Specifically, the end of the screw is connected to the suspended bearing housing via a spacer 566. The spacer 566 enables the connection between the suspended bearing housing and the clutch, while also preventing the suspended bearing housing from shaking.

[0070] In addition, the present invention also provides a vibrating cotton box, including a box body, a pair of feed rollers, and a novel transmission device for the feed rollers of the vibrating cotton box as described in the above specific embodiments.

[0071] Furthermore, this solution also includes two baffles, which are respectively set on both sides of the two feed rollers away from the feed port and between the two wall panels of the box.

[0072] By optimizing the design of both sides of the feed roller and adding a cotton-blocking device, the feeding accuracy of the feed roller is improved, thereby enhancing the quality of the nonwoven fabric.

[0073] Furthermore, this solution also includes a soft curtain assembly, which is disposed between the feed roller and a baffle plate near the feed roller. Specifically, the soft curtain assembly includes a clamping plate and a soft curtain, the clamping plate being fixed to the baffle plate or wall panel, and the clamping plate being used to hold the soft curtain.

[0074] The position of the soft curtain on the clamping plate is adjustable, allowing for easy adjustment of the length of the soft curtain extending beyond the clamping plate. This ensures that it is always in surface contact or has a gap fit with the feed roller, preventing fibers from entering the gap between the feed roller and the cotton baffle. The clamping design also facilitates the replacement of the soft curtain.

[0075] In one specific embodiment, reference is made to... Figures 1-6 As shown, the vibrating cotton box of this case includes a box body, a pair of feed rollers, and a novel transmission device for the feed rollers of the vibrating cotton box.

[0076] Among them, such as Figure 1 As shown, the housing includes a first wall panel 110 and a second wall panel 120 disposed opposite to each other, and a pair of feed rollers, namely a first feed roller 210 and a second feed roller 220, with a feed port for introducing fibers formed between the first feed roller 210 and the second feed roller 220.

[0077] The novel transmission device for the feeding roller of the vibrating cotton box includes a drive mechanism 410, a crank-slider mechanism 420, two lever frames, a lever shaft 530, two elastic reset elements, and two screws. The crank-slider mechanism 420 includes a crank 421, a slider shaft 422, a stop plate 423, and an adjusting bolt 424.

[0078] like Figure 2 As shown, bracket 111 is mounted on the first wall panel 110, and drive mechanism 410 is a geared motor, which is mounted on bracket 111.

[0079] The slider shaft 422 is mounted on the crank 421 and can slide freely on the crank 421. A stop plate 423 is provided on one side of the crank 421. An adjusting bolt 424 is connected and fixed to the slider shaft 422 via the stop plate 423. Rotating the adjusting bolt 424 causes the slider shaft 422 to move linearly on the crank 421, thereby adjusting the center distance between the slider shaft 422 and the output shaft of the drive mechanism 410. Rotating the adjusting bolt 424 clockwise moves the slider shaft 422 towards the output shaft of the drive mechanism 410, thus decreasing the center distance between them. Rotating the adjusting bolt 424 counterclockwise moves the slider shaft 422 away from the output shaft of the drive mechanism 410, thus increasing the center distance between them.

[0080] The two lever frames are a first lever frame 510 and a second lever frame 520. The first lever frame 510 and the second lever frame 520 are respectively disposed on both sides of the first wall plate 110 and the second wall plate 120. The lever shaft 530 is rotatably connected to the first wall plate 110 and the second wall plate 120 through the shaft seat 531. The first lever frame 510 and the second lever frame 520 are respectively connected and fixed to both ends of the lever shaft 530.

[0081] The elastic reset component includes a tension spring 541 and a hook 542. A first lever frame 510 and a second lever frame 520 are respectively connected to the tension spring 541, which in turn is connected to the hook 542. The hook 542 is connected to the first wall plate 110 and the second wall plate 120. An adjusting nut 543 is provided on each side of the hook 542 where it connects to the first wall plate 110 and the second wall plate 120. By rotating the adjusting nuts 543 on both sides, the relative position of the hook 542 is adjusted, thereby adjusting the tension of the tension spring 541.

[0082] First limit screws and second limit screws 552 are provided on both the first wall plate 110 and the second wall plate 120. By adjusting the positions of the first limit screws and the second limit screws 552, the swing angle range of the first lever frame 510 and the second lever frame 520 can be adjusted.

[0083] Both the first lever frame 510 and the second lever frame 520 are provided with two seated bearings 561 for connecting to the ends of the feed rollers. This allows the two ends of the first feed roller 210 to be connected and fixed to the first lever frame 510 and the second lever frame 520 respectively via the seated bearings 561, and the two ends of the second feed roller 220 to be connected and fixed to the first lever frame 510 and the second lever frame 520 respectively via the seated bearings 561.

[0084] A clutch 562 is provided on one side (shaft end) of the first feed roller 210 and the second feed roller 220, and the clutch 562 is fixed by retaining rings 563 on both sides. A first suspended bearing housing 564 and a spacer 566 are connected and fixed to the clutch 562 provided on one side of the first feed roller 210. A second suspended bearing housing 565 and a spacer 566 are connected and fixed to the clutch 562 provided on one side of the second feed roller 220. A third suspended bearing housing 567 and a fourth suspended bearing housing 568 are provided on the slider shaft 422. The third suspended bearing housing 567 is connected to the first suspended bearing housing 564 through a first screw 569, and the fourth suspended bearing housing 568 is connected to the second suspended bearing housing 565 through a second screw 5610.

[0085] When cotton accumulation between the first feed roller 210 and the second feed roller 220 is severe, causing them to jam and unable to continue operating, the clutch 562 prevents an increase in the load on the geared motor, allowing it to continue operating normally and avoiding damage to the motor, thus reducing the equipment's operating costs.

[0086] In addition, two cotton baffles are provided, namely the first cotton baffle 310 and the second cotton baffle 320. The first cotton baffle 310 and the second cotton baffle 320 are located on both sides of the first feed roller 210 and the second feed roller 220 (the front and rear sides as shown in the figure), in the middle of the first wall plate 110 and the second wall plate 120.

[0087] Simultaneously, a soft curtain assembly can be provided, including a first soft curtain 571 and a first clamping plate 581, a second soft curtain 572 and a second clamping plate 582. A first soft curtain 571 is disposed between the first feed roller 210 and the first baffle plate 310. The first soft curtain 571 is connected and fixed to the first baffle plate 310 via the first clamping plate 581, and the first soft curtain 571 is always in contact with the surface of the first feed roller 210. A second soft curtain 572 is disposed between the second feed roller 220 and the second baffle plate 320. The second soft curtain 572 is connected and fixed to the second baffle plate 320 via the second clamping plate 582, and the second soft curtain 572 is always in contact with the surface of the second feed roller 220. This ensures that fibers can only be fed into the gap between the first feed roller 210 and the second feed roller 220, preventing fibers from being transported to the lower cotton box from other sides. This improves the feeding accuracy of the feed rollers, effectively enhances the uniformity of the output fibers from the vibrating cotton box, and improves the quality of the nonwoven fabric.

[0088] The motion process of the feed roller is as follows: the geared motor drives the crank 421 to rotate, which in turn drives the slider shaft 422 to rotate. The first feed roller 210 is driven to reciprocate through the third suspended bearing seat 567, the first screw 569, the first suspended bearing seat 564 and the clutch 562; the second feed roller 220 is driven to reciprocate through the fourth suspended bearing seat 568, the second screw 5610, the second suspended bearing seat 565 and the clutch 562.

[0089] The first feed roller 210 is fixed on both sides to the first lever frame 510 and the second lever frame 520 respectively via bearings 561. The first lever frame 510 and the second lever frame 520 are connected to each other via lever shaft 530, ensuring synchronous movement of the first lever frame 510 and the second lever frame 520. Similarly, the second feed roller 220 is fixed on both sides to the first wall plate 110 and the second wall plate 120 respectively via bearings 561. This ensures that the distance between the first feed roller 210 and the second feed roller 220 remains consistent in the width direction during the oscillation of the first feed roller 210.

[0090] When it is necessary to increase the distance between the first feed roller 210 and the second feed roller 220, the first limit screw 551 is rotated clockwise to increase the distance between the first feed roller 210 and the second feed roller 220; when it is necessary to decrease the distance between the first feed roller 210 and the second feed roller 220, the second limit screw 552 is rotated counterclockwise to decrease the distance between the first feed roller 210 and the second feed roller 220.

[0091] The first lever frame 510 is connected to the tension spring 541 and the hook 542. The hook 542 is connected to the first wall plate 110 via the adjusting nut 543. The second lever frame 520 is connected to the tension spring 541 and the hook 542. The hook 542 is connected to the second wall plate 120 via the adjusting nut 543. The first lever frame 510 and the second lever frame 520 can swing around the lever shaft 530 as the rotation center. The tension of the tension spring 541 can be adjusted by adjusting the relative position of the hook 542 and the adjusting nut 543. At the same time, the first wall plate 110 and the second wall plate 120 are each provided with a first limiting screw 551 and a second limiting screw 552, thereby limiting and adjusting the swing amplitude of the first lever frame 510 and the second lever frame 520. When a large fiber block passes between the first feed roller 210 and the second feed roller 220, the fiber block's own force causes the gap between the first feed roller 210 and the second feed roller 220 to expand and increase. Under the action of the tension spring 541, after the large fiber block passes through the gap between the first feed roller 210 and the second feed roller 220, the first feed roller 210 returns to its previous working position. This setting can effectively improve the adaptability of the vibrating cotton box to the raw materials of the product.

[0092] When the operating speeds of the first feed roller 210 and the second feed roller 220 need to be adjusted based on product raw materials, production processes, etc., there is no need to replace related parts. Simply changing the center distance between the slider shaft 422 and the output shaft of the geared motor will adjust the operating speeds of the first feed roller 210 and the second feed roller 220. Rotating the adjusting bolt 424 clockwise moves the slider shaft 422 towards the output shaft of the geared motor, thereby reducing the center distance between the slider shaft 422 and the output shaft of the geared motor. This reduces the operating speeds of the first feed roller 210 and the second feed roller 220, increasing their rotational torque.

[0093] Similarly, rotating the adjusting bolt 424 counterclockwise causes the slider shaft 422 to move away from the output shaft of the geared motor, thereby increasing the center distance between the slider shaft 422 and the output shaft of the geared motor. This increases the operating speed of the first feed roller 210 and the second feed roller 220 and reduces their rotational torque.

[0094] The purpose of this invention is to provide a novel transmission device for a feeding roller in a vibrating cotton box. The transmission device has been redesigned and re-rotated, changing the feeding roller from continuous rotation to reciprocating rotation. When encountering a large fiber block, the distance between the two feeding rollers can be increased. Furthermore, a geared motor protection device is added to the feeding roller to prevent damage to the geared motor in extreme cases.

[0095] Meanwhile, without replacing relevant parts, the operating speed of the feed roller can be adjusted, and the cotton-blocking devices on both sides of the feed roller can be optimized, thereby improving the feeding accuracy of the feed roller. This increases the working efficiency of nonwoven machinery and the output of nonwoven fabrics, while reducing the labor intensity of operators and the maintenance costs of equipment.
