Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a spacing-adjustable slitting machine. Background Art

[0002] Non-woven fabric is a kind of textile made without knitting or weaving. It is made by fiber stacking, bonding, fusion and other processes. It has the characteristics of uniform fiber distribution, dense structure, softness and breathability. Non-woven fabric is widely used in various fields, such as medical and health care, household goods, industrial supplies, etc. In the production process of non-woven fabric, slitting is an important step. Slitting is the process of cutting non-woven fabric rolls into certain sizes and widths to meet product requirements for different uses and needs.

[0003] According to the publication number: CN218707899U, a cutting spacing adjustable slitting machine includes a base, a pair of frames are symmetrically mounted on the base, a cutter assembly is fixedly connected between the two frames; a winding roller and an unwinding roller are respectively provided at both ends of the frame, and one end of the winding roller is connected to a motor; the cutter assembly includes a rod body, both ends of the rod body are fixedly connected to a mounting plate, and the mounting plate is fixedly connected to the surface of the frame; a plurality of cutters are fixedly connected to the rod body along its length direction, and one end of the cutter is fixedly connected to a connecting sleeve that matches the rod body, and the connecting sleeve is fixedly connected to the rod body by a fastening bolt. The utility model can adjust the width of the polymer film after slitting by changing the position of the cutter on the rod body, and adjust the tension of the polymer film by changing the height difference between the two pressure rollers, thereby greatly improving the applicability of the slitting machine.

[0004] In the process of implementing this utility model, the applicant found that there are at least the following problems in the prior art:

[0005] 1. The spacing between the cutters needs to be adjusted by unlocking the fastening bolts one by one. Unlocking and adjusting the spacing between each cutter one by one requires a certain amount of time and labor cost. In addition, the adjustment process depends on the operator's subjective visual inspection, which may result in errors. Different operators may have different subjective judgments, which may lead to inaccurate cutting dimensions or unstable product quality.

[0006] 2. Before the non-woven fabric is cut, dust is easily attached to the surface. When the non-woven fabric is cut, these dust and impurities will interfere with the cutting process, resulting in unsatisfactory cutting results. The cutting of the non-woven fabric is also prone to produce debris residue. This is because during the cutting process, the strength of the non-woven fabric fiber is very high, and higher pressure and speed are required during cutting. This high pressure and speed will cause some non-woven fabric fibers to break or fall off, forming debris or residues, which may affect subsequent processing operations. Utility Model Content

[0007] In view of the deficiencies of the prior art, the utility model provides a spacing-adjustable slitting machine, aiming to solve the problems in the non-woven fabric slitting process in the prior art.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A spacing adjustable slitting machine, comprising:

[0010] The slitting box is the main body of the adjustable spacing slitting machine;

[0011] Non-woven fabric retracting rollers are provided on both sides of the slitting box;

[0018] Preferably, a non-woven fabric pressure roller is connected to the lower part of the interior of the slitting box through a second electric push rod, and the height of the non-woven fabric pressure roller is lower than the height of the non-woven fabric retracting and releasing roller.

[0019] Preferably, the plurality of movable sleeves are threadedly connected to the inner bidirectional screw rod and the outer bidirectional screw rod, and the plurality of movable sleeves are also slidably connected to the center rod.

[0020] Preferably, the two rubber sheets are respectively located on both sides of the cutter, and the bottom heights of the two rubber sheets are lower than the height of the cutter.

[0021] Preferably, one end of the non-woven fabric retracting and unwinding roller, the inner bidirectional screw rod and the outer bidirectional screw rod are all connected to a drive motor, and a protective door is hinged on the outer surface of the slitting box.

[0022] Preferably, a first electric push rod installed on the top of the slitting box is connected to the middle of the top of the bracket, and guide telescopic rods installed on the top of the slitting box are connected to both sides of the top of the bracket.

[0023] Preferably, the two guide telescopic rods are symmetrically arranged with the first electric push rod as the center, and the length of the guide telescopic rod is consistent with the length of the first electric push rod.

[0024] The present invention provides a spacing adjustable slitting machine, which has the following beneficial effects:

[0025] 1. By setting a center rod, an inner bidirectional screw rod, an outer bidirectional screw rod, and a movable sleeve, when the slitting distance needs to be adjusted before the non-woven fabric is slitting, the staff can drive the motor to make the inner bidirectional screw rod and the outer bidirectional screw rod rotate the same number of circles, so that the two movable sleeves on the inner bidirectional screw rod can be moved closer to or farther from each other along the center rod, and the two movable sleeves on the outer bidirectional screw rod can be moved closer to or farther from each other along the center rod, so as to timely change the distance between multiple cutters, ensure that the distance between the cutters is accurately and reliably adjusted, reduce the time and labor cost of manual operation, and reduce the error caused by subjective visual inspection;

[0026] 2. By setting the rubber sheet, when the non-woven fabric passes through the cutter, the bottom height of the rubber sheet is lower than the height of the cutter, so the rubber sheet will fit tightly to the surface of the non-woven fabric, and as the non-woven fabric is transmitted through the non-woven fabric retracting roller, the dust on the surface of the non-woven fabric can be swept away by the rubber sheets on both sides of the cutter, and due to the local antistatic property of the rubber itself, the rubber sheet can absorb and neutralize part of the static charge, reduce the accumulation of static electricity, play a certain antistatic effect, can reduce the adhesion of dust and impurities on the surface of the non-woven fabric, improve the cleaning effect, and reduce interference with the slitting process.

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example: Figure 1 As shown, a spacing adjustable slitting machine comprises: a slitting box 1 is in a rectangular shape, a cutting area is arranged in the middle, a cutter 9 can be installed above the cutting area, and is used to slit the non-woven fabric material; non-woven fabric retracting rollers 2 are installed on both sides of the slitting box 1; the non-woven fabric retracting rollers 2 are in a cylindrical shape, and are used to fix and convey the non-woven fabric material to be slit; the surface of the roller should be smooth so as to smoothly convey the non-woven fabric material; one end should be connected to a driving motor to drive the roller to rotate to convey the non-woven fabric material; the protective door 3 is a safety device for protecting the staff, and can be hinged In the form of a door, when the slitting machine is in operation, the protective door should be closed to prevent the staff from contacting the running mechanical parts and causing danger. The non-woven fabric can be taken up and slitting by driving the motor to control the rotation of the non-woven fabric take-up roller 2. When the non-woven fabric needs to be slitting, the non-woven fabric material to be slit is placed between the non-woven fabric take-up rollers 2, and one of the rollers is controlled to rotate by the driving motor to convey the non-woven fabric material to the cutting area, and then the cutting knife is used for slitting. After slitting, the slit non-woven fabric is rolled up and rewound using another non-woven fabric take-up roller 2.

[0035] like Figure 2 As shown, the first electric push rod 11 can adopt a linear electric push rod, and its function is to push the bracket 4 up and down by controlling the extension and retraction of the electric push rod, so as to adjust the position of the cutter 9 and realize the slitting of the non-woven fabric. The guide telescopic rod 12 can adopt a cylindrical shape, and the length is the same as that of the first electric push rod 11. The function of the two guide telescopic rods 12 is to provide balanced and stable support when the bracket 4 moves up and down, ensuring that the movement trajectory of the bracket 4 is vertical and stable. The second electric push rod 13 can adopt a linear electric push rod. The non-woven fabric pressure roller 14 adjusts its height by the extension and retraction of the second electric push rod 13, so as to support the slit non-woven fabric. The cooperation of these components can realize automatic slitting and support of the non-woven fabric.

[0036] like Figure 4As shown, the center rod 5 can be cylindrical in shape, and its function is to provide support and balance to ensure that the movement trajectories of the inner and outer bidirectional screw rods 6 and 7 are vertical and stable. The inner and outer bidirectional screw rods 6 and 7 can be threaded in opposite spiral directions, and one end of each of the threaded screw rods is connected to the drive motor through a connecting device. Their function is to make the movable sleeve 8 move along the center rod 5. The movable sleeve 8 is sleeve-shaped, and a cutter 9 is installed at the bottom. They are connected to the inner and outer bidirectional screw rods 6 and 7 through threads, and connected to the center rod 5 through sliding, so as to adjust the spacing between the cutters.

[0037] like Figure 3 As shown, the rubber sheet 10 can be in the shape of a strip, and its material can be selected from a rubber material with moderate hardness, wear resistance, and partial elasticity. They can use bolts, nuts, etc. to firmly fix the rubber sheet 10 on both sides of the bracket 4. When the non-woven fabric passes through the cutter 9, the rubber sheet 10 will fit tightly to the surface of the non-woven fabric. Through the action of friction and elastic force, the dust on the surface of the non-woven fabric can be swept away. At the same time, due to the anti-static properties of the rubber itself, the rubber sheet 10 can absorb and neutralize part of the static charge, reduce the adhesion of dust and impurities on the surface of the non-woven fabric, and achieve a certain anti-static effect.

[0038] Working principle: First, when the slitting distance needs to be adjusted before the non-woven fabric is slid, the staff can drive the motor to make the inner bidirectional screw 6 and the outer bidirectional screw 7 rotate the same number of circles, so that the two movable sleeves 8 on the inner bidirectional screw 6 can be moved closer to or farther away from each other along the center rod 5, and the two movable sleeves 8 on the outer bidirectional screw 7 can be moved closer to or farther away from each other along the center rod 5, so as to timely change the spacing between multiple cutters 9, which can ensure that the spacing between the cutters is accurately and reliably adjusted, reduce the time and labor cost of manual operation, and reduce the error caused by subjective visual inspection. Then, by driving the motor by luck, one non-woven fabric retracting roller 2 can release the non-woven fabric, and the other non-woven fabric retracting roller 2 can rewind the slit non-woven fabric. At the same time, by running the second electric push rod 13 The non-woven fabric pressure roller 14 can be pushed up and down to support the non-woven fabric to be cut, and the bracket 4 can be pushed up and down by running the first electric push rod 11, so that the cutter 9 in the bracket 4 can cut the non-woven fabric, and when the non-woven fabric passes through the cutter 9, the rubber sheet 10 will be tightly attached to the surface of the non-woven fabric, and as the non-woven fabric passes through the non-woven fabric retracting roller 2, the rubber sheets 10 on both sides of the cutter 9 can sweep away the dust on the surface of the non-woven fabric, and due to the local antistatic properties of the rubber itself, the rubber sheet 10 can absorb and neutralize part of the static charge, reduce the accumulation of static electricity, and play a certain anti-static effect, which can reduce the adhesion of dust and impurities on the surface of the non-woven fabric, improve the cleaning effect, reduce the interference with the cutting process, and make the non-woven fabric cutting more convenient and safe.
