Description

Technical Field

[0001] The present invention relates to the related field of medical supplies production and processing, and specifically to a slitting device for producing medical non-woven fabrics. Background Art

[0002] Non-woven fabric is a new generation of environmentally friendly material, which has the characteristics of moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, recyclable, etc. This material can be naturally decomposed outdoors in 90 days, and has a service life of up to 5 years indoors. When burned, it is non-toxic, odorless, and leaves no residue, thus not polluting the environment.

[0003] When non-woven fabric is used in the medical field for processing, after its impregnation work is completed, it needs to be slit according to specific size widths according to different manufactured products.

[0004] Currently, traditional slitting work consumes a large amount of manpower, the slitting size control is not accurate enough, and it is difficult to fix the cutting position. Summary of the Invention

[0005] Now, in order to overcome the defects existing in the above technology, the present invention proposes a slitting device for producing medical non-woven fabrics.

[0006] The technical problems to be solved by the present invention are realized by the following technical solutions:

[0007] A slitting device for producing medical non-woven fabrics includes a slitting table and a support frame installed above the slitting table; a collecting roller is rotatably installed on the support frame; through holes are evenly distributed on the collecting roller, and a splitting block is slidably installed at each through hole; the splitting block is matched with a transfer control component; the collecting roller is connected with a driving component; a slitting control component is installed on the right side of the slitting table. The collecting roller is used for winding and collecting non-woven fabrics. The splitting block can automatically expand to tension the non-woven fabric for easy cutting. The transfer control component is used to control the expansion and contraction of the splitting block. The driving component is used to control the rotation of the collecting roller to facilitate the pre-winding and collecting work and the slitting work.

[0008] Every 6 through holes form a group, and each group of through holes is evenly distributed linearly along the axial direction of the collecting roller; the 6 through holes in each group are evenly distributed in a circular direction. The distribution and setting of the through holes and the splitting blocks are all for facilitating the subsequent development of the slitting work.

[0009] The beneficial effects of the present invention are:

[0010] Most of the positioning and slitting work of the present invention is automatically implemented by the equipment, which can relatively save a large amount of manual labor. By fixing each single slitting unit, the width size of the non-woven fabric after slitting can be accurately controlled, making the slitting size relatively more precise. The opening of the slitting port can play a certain protective role for the equipment and ensure the smooth progress of the slitting work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention, not all of it. Based on these embodiments, other embodiments obtained by those skilled in the art without creative efforts are within the protection scope of the present invention.

[0021] Such as Figure 1As shown in the figure, a slitting device for producing medical non-woven fabrics includes a slitting table 1 and a support frame 2 installed above the slitting table 1; a collecting roller 3 is rotatably installed on the support frame 2; through holes 3a are evenly distributed on the collecting roller 3, and a splitting block 4 is slidably installed at each through hole 3a; the splitting block 4 is equipped with a transfer control component; the collecting roller 3 is connected with a driving component; a slitting control component is installed on the right side of the slitting table 1. The collecting roller 3 is used for winding and collecting non-woven fabrics. The splitting block 4 can automatically expand to tension the non-woven fabric for easy cutting. The transfer control component is used to control the expansion and contraction of the splitting block 4. The driving component is used to control the rotation of the collecting roller 3 to facilitate the pre-winding and collecting work and the slitting work.

[0022] As Figures 1 to 3 shown, every 6 through holes 3a form a group, and each group of through holes 3a is evenly distributed linearly along the axial direction of the collecting roller 3; the 6 through holes 3a in each group are evenly distributed in a circular direction. The distribution and setting of the through holes 3a and the splitting blocks 4 are for the convenience of subsequent slitting work.

[0023] As Figure 3 and Figure 4 shown, each splitting block 4 is provided with a slitting notch 4a. The slitting notch 4a is convenient for the subsequent cutting.

[0024] As Figure 3 and Figure 4 shown, each splitting block 4 is respectively provided with an inner extension part 4b and a convex round part 4c; a spring 5 connected to both of them is provided between the inner extension part 4b and the inner wall of the collecting roller 3. That is, the contraction of the splitting block 4 can be controlled by the elastic force of the spring 5.

[0025] As Figure 2 shown, the driving component includes an upper pulley 6 connected to the collecting roller 3, a transmission belt 7 connecting the upper pulley 6, a lower pulley 8 connecting the transmission belt 7, and a motor 9 connecting the lower pulley 8; the motor 9 is fixedly installed on the slitting table 1. That is, through the transmission of the transmission belt, the collecting roller 3 is driven to rotate.

[0026] As Figure 3 , Figure 4 and Figure 7 shown, the transfer control component includes a central rotating shaft 10 connected to the collecting roller 3 through a bearing; a number of central rotating blocks 11 are welded on the central rotating shaft 10, and each central rotating block 11 is provided with 6 arc-shaped surfaces 11a that are in contact with the corresponding convex round parts 4c. That is, when the arc-shaped surfaces 11a rotate along with the central rotating shaft 10, the convex round parts 4c can be pushed, so that all the splitting blocks 4 automatically expand.

[0027] As Figure 7 shown, a handle part 10a is provided on the front side of the central rotating shaft 10. This setting is for the convenience of manual operation.

[0028] As Figure 1 and Figure 5 shown, the slitting control component is composed of a square slide bar 12 fixedly installed on the slitting table 1 and several slitting units; several square holes 12a are provided on the square slide bar 12. The number and distribution positions of the square holes 12a correspond to those of each group of through holes 3a. Each slitting unit can perform single-knife slitting.

[0029] As Figure 5 shown, each slitting unit is composed of a sliding base 13 slidably installed on the square slide bar 12, a three-axis cylinder 14 installed on the sliding base 13, a cutting knife 15 connected to the three-axis cylinder 14, and a locking mechanism. The locking mechanism can cooperate with the corresponding square hole 12a to fix the current slitting unit.

[0030] As Figure 2 and Figure 6 shown, the locking mechanism is composed of an L-shaped sliding rod 16 slidably installed at the lower part of the sliding base 13 and a hydraulic cylinder 17 connected to the L-shaped sliding rod 16; the L-shaped sliding rod 16 is adapted to the square hole 12a; the hydraulic cylinder 17 is fixedly installed at the lower part of the sliding base 13. That is, by controlling the L-shaped sliding rod 16 to insert into the square hole 12a, the fixation of a single slitting unit can be achieved.

[0031] Before the present invention is used, the made non-woven fabric needs to be wound onto the collecting roller 3 first.

[0032] Furthermore, manually hold the handle part 10a, control the central rotating shaft 10 to rotate a certain angle, thereby pushing each one, so that all the expanding blocks 4 automatically expand, thereby tensioning the wound non-woven fabric.

[0033] Furthermore, manually adjust the corresponding sliding base 13 to slide to a specific position on the square slide bar 12 according to the actual size requirements, and control the L-shaped sliding rod 16 to insert into the corresponding square hole 12a through the hydraulic cylinder 17 to achieve fixation.

[0034] Finally, while the three-axis cylinder 14 pushes the cutting knife 15 to cut to the left, under the driving of the motor 9 and the transmission action of the transmission belt 7, the collecting roller 3 rotates at a high speed, thereby completing the slitting work of the non-woven fabric.

[0035] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
