Description

Technical Field

[0001] This invention relates to carding equipment in nonwoven machinery, specifically to an upper feed plate adjustment structure that is applicable to various carding machines, effectively reduces the carding gap during carding feed, and is suitable for processing fibers of different lengths. Background Technology

[0002] There are generally two types of feeding methods for carding machines: bottom feeding plate feeding and top feeding plate feeding. Bottom feeding plate feeding is further divided into single licker roller feeding and double licker roller feeding.

[0003] The advantages of using a single-roller bottom-feeding board are convenient and reliable processing and adjustment, and a large feeding capacity. The disadvantages are: ① The carding spacing is fixed and cannot be adjusted; ② Because it feeds against the grain, it causes significant damage to the fibers, especially shorter fibers such as raw cotton and degreased cotton.

[0004] The advantages of double-licker-in roller feeding on the bottom feedboard are convenient and reliable processing and adjustment, and a large feeding capacity. Unlike single-licker-in roller feeding on the bottom feedboard, double-licker-in roller feeding is forward feeding, almost comparable to feeding from the top feedboard. The disadvantages are: ① The carding spacing is fixed and cannot be adjusted; ② The addition of a licker-in roller transfer roller increases the complexity of the structure and transmission, leading to higher costs.

[0005] Top-feed slab is the most advanced feeding mode among the three feeding methods. Its advantages are: ① The combing spacing can be freely adjusted, suitable for processing different types of fibers; ② Forward feeding minimizes fiber damage. Disadvantages are: ① Although the combing spacing is adjustable, the straight-line design of the nose tip of the top-feed slab and the licker-in roller limits the minimum combing spacing to 37mm. Any smaller and the nose tip will hit the licker-in roller, potentially causing an accident. The combing spacing adjustment range is between 37mm and 65mm. This range is sufficient for chemical fibers with a length between 38mm and 78mm; however, for shorter fibers like raw cotton and degreased cotton with a length of 30mm or less, the combing spacing is too large, failing to achieve the ideal feeding effect. ② The processing of the top-feed slab and the adjustment of the combing spacing are more complex and difficult (see...). Figure 7 , 8 (As shown in 9 and 10). Summary of the Invention

[0006] The present application aims at the above-mentioned deficiencies of the prior art and provides an upper feed plate adjustment structure capable of effectively reducing the carding gauge.

[0007] The object of the present application can be achieved by the following technical measures:

[0008] The upper feed plate adjustment structure capable of effectively reducing the carding gauge of the present application comprises a feed roller and a licker-in roller arranged in parallel, and an upper feed plate installed above the feed roller through an adjusting mechanism capable of swinging around the shaft of the feed roller body; the feed nose of the upper feed plate above the feed roller extends along the curved surface of the feed roller body into the triangular area between the feed roller body and the licker-in roller body, and the two side surfaces of the feed nose extending between the feed roller body and the licker-in roller body are respectively concave arc surface structures matching the outer cylindrical surface of the feed roller body and the licker-in roller body; the feed nose of the upper feed plate can further sink into the triangular area between the feed roller body and the licker-in roller body, and the minimum carding gauge Y of the fibers fed into the licker-in roller from the upper path of the feed roller can be reduced to 30mm. min The object of the present application can be achieved by the following technical measures:

[0009] In the present application, the upper feed plate is installed on the left and right shaft ends of the feed roller through left and right upper feed plate support screws, bearings and bearing seats; support frames are respectively installed on the left and right ends of the upper feed plate through bolts on the front side of the upper feed plate; through shafts are installed in the mounting holes of the two support frames through shaft sleeves, and the worm shafts of the left and right double-input shaft worm gear reduction boxes fixedly installed on the outer cylindrical surfaces of the corresponding shaft sleeves are respectively combined with the corresponding ends of the through shafts through couplings, for realizing the synchronous operation of the left and right double-input shaft worm gear reduction boxes and avoiding the distortion during adjustment; the power output screws of the left and right double-input shaft worm gear reduction boxes are respectively connected to the internally threaded holes provided on the rotatable short shaft ends installed on the left and right sides of the feed roller mounting seat through threaded connection, and two limiting nuts with a distance of 30mm-65mm are respectively fixed on the left and right power output screws, for controlling the adjustment range of the Y value of the feed nose of the upper feed plate in the triangular area between the feed roller body and the licker-in roller body, so as to avoid accidents caused by excessive adjustment.

[0010] The driving of the double-input shaft worm gear reduction box of the application is realized by a hand wheel installed at the end of the worm shaft. The double-input shaft worm gear reduction box is driven by rotating the hand wheel, which further drives the upper feed plate to rotate anticlockwise or clockwise around the outer circle of the feed roller body, so as to achieve the purpose of adjusting the carding gauge Y. The adjustment range of Y value is 30mm-65mm.

[0011] The distance between the upper feed plate and the feed roller body of the feed roller is the distance A, the minimum distance between the roller body of the feed roller and the roller body of the taker-in is the distance B, and the distance between the point A and the point B is the carding gauge Y. The adjustment range of Y value is 30mm-65mm, so as to adapt to the processing of fibers of various lengths. The two side surfaces of the feed nose of the upper feed plate are designed as concave arc surface structures matched with the outer cylindrical surfaces of the roller body of the feed roller and the roller body of the taker-in, so as to effectively reduce the value of the carding gauge Y, so that the fibers of 28-78mm are within the processing range, and the variety of fibers that can be processed is increased.

[0012] The gap of the distance point B is 0.5-0.6mm, and the rotation speed of the taker-in at the distance point B is fast. The gap of the distance point A is 0.5-0.6mm, and the rotation speed of the feed roller at the distance point A is slow. The speed draft at the distance points A and B is greater than or equal to 26:1. The difference in speed and the shrinkage of the fibers at the distance points A and B make the initially thick fibers be extruded, thinned and uniformly fed into the taker-in.

[0013] The beneficial effects of the application are as follows:

[0014] 1. The two side surfaces of the feed nose of the upper feed plate are designed as concave arc surface structures matched with the outer cylindrical surfaces of the roller body of the feed roller and the roller body of the taker-in, so that the feed nose of the upper feed plate can further penetrate into the triangular area between the roller body of the feed roller and the roller body of the taker-in. Thus, the minimum carding gauge Ymin can be reduced to 30mm. The minimum carding gauge is suitable for processing short fibers.

[0015] 2. By rotating the hand wheel fixed on the worm gear reduction box of the upper feed plate, the upper feed plate can rotate around the outer circle of the feed roller body, so as to freely adjust the carding gauge Y. The adjustable range of Y is 30mm-50mm. The beneficial effect is that, in addition to being suitable for processing chemical fibers with a length of 38mm-78mm, it is also suitable for processing relatively short fibers such as raw cotton and degreased cotton with a length of less than or equal to 30mm, so as to widen the range of fibers that can be processed by the whole machine, and be suitable for more types of non-woven production processes.

DETAILED DESCRIPTION

[0027] The application will be further described below in combination with the embodiments (the attached drawings):

[0028] As Figure 1 , 2 , 3, 4, the upper cotton plate adjustment structure capable of effectively reducing the carding gauge of the application comprises the parallel arranged cotton feeding roller 8, the licker-in 9, the upper cotton plate 3 installed above the cotton feeding roller 8 through the adjusting mechanism capable of swinging around the shaft center of the cotton feeding roller body; the cotton feeding nose tip of the upper cotton plate 3 located above the cotton feeding roller 8 extends along the curved surface of the roller body of the cotton feeding roller into the triangular area between the roller body of the parallel arranged cotton feeding roller 8 and the roller body of the licker-in 9, and extends to both sides of the cotton feeding nose tip between the roller body of the cotton feeding roller and the roller body of the licker-in, which are respectively the concave curved surface structure matched with the outer cylindrical surface of the roller body of the cotton feeding roller and the roller body of the licker-in; so that the cotton feeding nose tip of the upper cotton plate 3 can further penetrate into the triangular area between the roller body of the cotton feeding roller and the roller body of the licker-in, and the minimum carding gauge Y min of the fiber fed into the licker-in 9 from the upper path of the cotton feeding roller 8 can be reduced to 30mm.

[0029] In the application, the upper cotton plate 3 is installed at the left and right shaft ends of the cotton feeding roller through the left and right upper cotton plate supporting screws 22, bearings and bearing seats 6; the support frames 16 are respectively installed at the left and right ends of the upper part of the front side of the upper cotton plate 3 through the bolts 21; the through shafts 20 are respectively installed in the mounting holes of the two support frames 16 through the shaft sleeves 19, the worm shafts of the left and right double input shaft worm gear reducers 2 fixedly installed on the outer cylindrical surfaces of the corresponding end shaft sleeves 19 are respectively combined with the corresponding ends of the through shafts 20 through the couplings, which are used to realize the synchronous operation of the left and right double input shaft worm gear reducers and avoid the distortion during adjustment; the power output screws (adjusting lead screws) 13 of the left and right double input shaft worm gear reducers 2 are respectively connected with the inner threaded holes provided at the end portions of the rotatable short shafts 14 installed at the left and right sides of the cotton feeding roller mounting seat 7 through the threaded connection, and two limiting nuts 12 with a distance of 30mm-65mm are respectively fixed on the left and right power output screws 13, which are used to control the adjustment range of the Y value of the cotton feeding nose tip of the upper cotton plate in the triangular area between the roller body of the cotton feeding roller and the roller body of the licker-in, so as to avoid accidents caused by excessive adjustment.

[0030] The driving of the double input shaft worm gear reducer 2 of the application is realized through the hand wheel installed at the end of the worm shaft, the double input shaft worm gear reducer is driven by rotating the hand wheel, and then the upper cotton plate is driven to rotate counterclockwise or clockwise around the outer circumference of the roller body of the cotton feeding roller, so as to achieve the purpose of adjusting the carding gauge Y, and the adjustment range of the Y value is 30mm-65mm.

[0031] The distance between the point A and the point B is the fiber carding gauge Y. The adjustment range of the value of Y is 30mm-65mm, so as to adapt to the processing of fibers of various lengths. The two side surfaces of the top feeding nose of the top feeding plate are respectively designed as concave arc surface structures matched with the outer cylindrical surfaces of the roller bodies of the cotton roller and the roller bodies of the licker-in roller. The purpose is to effectively reduce the value of the carding gauge Y, so that fibers of 28-78mm are within the processing range, and the variety of fibers that can be processed is increased (see Figure 5 、 6 )。

[0032] More specifically (as shown in Figure 2 、 5 , 6):

[0033] 1. The top feeding plate 3 is located on the top of the feeding roller 8, and the fibers are fed into the licker-in roller in the path from the top of the feeding roller. The distance between the point A and the point B is the fiber carding gauge Y.

[0034] 2. The gap of the point B is 0.5-0.6mm, and the rotation speed of the licker-in roller at the point B is fast. The gap of the point A is 0.5-0.6mm, and the rotation speed of the feeding roller at the point A is slow. The speed draft at the points B and A is ≥26:1. The difference in speed and the contraction of the fibers at the points A and B make the initially thick fibers be extruded, thinned, and uniformly fed into the licker-in roller.

[0035] 3. The shape of the contact between the top feeding plate nose and the licker-in roller 9 is designed as an arc line, so that the top feeding plate nose can further penetrate into the triangular area between the roller body of the feeding roller and the roller body of the licker-in roller. Thus, the minimum carding gauge Y min can be reduced to 30mm.

[0036] 4. When it is necessary to adjust the carding gauge Y, the hand wheel 15 is rotated, the worm gear reducer box drives the power output screw rod (adjusting screw) 13 to rotate, the power output screw rod 13 rotates relative to the screw hole on the rotatable short shaft 14, the power output screw rod generates linear displacement, thereby driving the top feeding plate 3 to rotate around the axis of the feeding roller 8 as the center, and further adjusting the value of the carding gauge Y. When the carding gauge is adjusted to the required value, the clamping screw 10, the locking nut 11 and the clamping screw 18 are tightened. Two nuts 12 are respectively welded on the power output screw rod 13, which are used to control the adjustment range of the value of Y to be between 30mm and 65mm. If the adjustment range is exceeded, the adjustment cannot be made, so as to avoid accidents caused by excessive adjustment.
