Description

Technical Field

[0001] This invention relates to the technical field of slitting machines, and specifically to a slitting machine for agricultural biodegradable nonwoven fabrics. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, is usually made from agricultural biomaterials. It is biodegradable and the products made from it are usually composed of oriented or random fibers. It is called cloth because it has the appearance and some properties of cloth. To facilitate the slitting of non-woven fabric, slitting machines are usually used to cut the non-woven fabric into slitting slices.

[0003] According to Chinese patent number CN 218809440 U, ​​a nonwoven fabric slitting machine is disclosed, comprising two control boxes arranged opposite each other. Slitting rollers are located inside the two control boxes, and slitting slices are mounted on the rollers. Tensioning rings are installed on the sides of the slitting slices, and each tensioning ring has a first half-ring and a second half-ring. A first connecting shaft is movably mounted at one end of the first half-ring, and a connecting plate is movably connected to the first half-ring via the first connecting shaft. A second connecting shaft is movably mounted on the upper part of the connecting plate, and the connecting plate is connected to the second half-ring via the second connecting shaft. A force-applying plate is movably connected to one end of the second half-ring, and a locking ring is movably mounted on the side of the second half-ring closest to the force-applying plate. This device moves the slitting slices to the required scale position, accommodating slitting cuts of different widths; the locking device of the tensioning rings fixes the slitting slices, ensuring stability and making it highly practical.

[0004] The existing technical solution described above uses a pressure plate and a locking ring, along with a tensioning ring and slitting slices set inside the first half-ring and the second plate ring, to fix the slitting slices. This allows the spacing between the slitting slices to be adjusted according to the required slitting width before operation, thus adapting to slitting cuts of different widths. However, in actual adjustment, each slice needs to be adjusted by repeatedly adjusting the installation position of the cutter with reference to a ruler, making the actual operation quite troublesome. Moreover, multiple cutter positions need to be adjusted each time, making it difficult to control the adjustment accuracy and inconvenient for practical use. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the problem that existing nonwoven fabric slitting machines require repeated adjustment of the installation position of the cutter by referring to a ruler when adjusting each slice, which makes the actual operation more troublesome, and multiple cutter positions need to be adjusted each time, making it difficult to control the adjustment accuracy.

[0006] The technical solution adopted to solve the above technical problems is: A biodegradable nonwoven fabric slitting machine for agricultural use includes a receiving platform and a control box fixed to its top. A slitting roller is rotatably connected inside the control box. Positioning grooves are evenly arranged along the axial direction of the outer side wall of the slitting roller. A slitting seat is threadedly connected to one of the positioning grooves via a locking bolt. A fastening head is inserted into the locking bolt. A motor is connected to the upper end of the fastening head. A lifting mechanism is connected to one side of the motor. A horizontally moving translation mechanism is connected to one side of the lifting mechanism. A limit sleeve is connected to one side of the motor. The limit sleeve is fitted onto one side of the slitting seat to control the relative position of the relatively sliding slitting seat and the slitting roller to remain fixed.

[0007] As a preferred technical solution of the present invention, it further includes a discharge roller and a receiving roller respectively disposed on both sides of the slitting roller. The discharge roller and the receiving roller are rotatably installed inside the control box. One side of each of the plurality of slitting seats is connected to a slitting blade by a first bolt. The motor moves up and down by a lifting mechanism, while the fastening head inserted into the locking bolt rotates. Under the limit of the connecting block, the relative connection between the slitting roller and the slitting seat is quickly completed.

[0008] As a preferred embodiment of the present invention, the lifting mechanism is a first cylinder, and the output end of the first cylinder is fixedly connected to the outer wall of the motor.

[0009] As a preferred embodiment of the present invention, the translation mechanism includes a mounting base fixedly installed at the bottom of the first cylinder. A lead screw and a limiting rod are respectively symmetrically provided inside the mounting base. The lead screw is threadedly connected inside the mounting base, and the limiting rod is slidably connected inside the mounting base. Both the limiting rod and the lead screw are rotatably installed inside the control box.

[0010] As a preferred embodiment of the present invention, a first drive wheel is fixedly connected to one end of the lead screw, and a second drive wheel is rotatably connected to one side inside the control box. The first drive wheel and the second drive wheel are connected by a rack and pinion belt drive.

[0011] As a preferred embodiment of the present invention, connecting blocks are installed opposite each other on the outer side wall of the limiting sleeve, and both connecting blocks are fixedly installed on the outer side wall of the motor.

[0012] As a preferred embodiment of the present invention, one end of the slitting roller passes through the control box and is connected to a swing block. The end of the swing block away from the slitting roller is rotatably connected to a follower block. The lower end of the follower block is rotatably connected to a second cylinder. One side of the second cylinder is fixedly installed inside the control box. After the control fastening head is disengaged from the positioning groove and the slitting seat, the control second cylinder pulls the follower block and the swing block downward, thereby controlling the slitting roller to drive multiple slitting blades to flip and adjust the cutting angle of the slitting blades.

[0013] As a preferred embodiment of the present invention, a buffer pad is provided below the inner wall of each of the plurality of positioning grooves, and the plurality of buffer pads are made of rubber material.

[0014] The beneficial effects of this invention are as follows: 1. This invention effectively solves the problems of cumbersome adjustment and difficult precision control of slitting blade spacing in the prior art by setting a slitting roller with uniformly distributed positioning grooves and a motor-driven locking mechanism. Specifically, by coordinating the translation mechanism and the lifting mechanism, the slitting seat is first kept stationary by the limit sleeve, and the fastening head can be precisely moved above the target positioning groove and pressed down. The motor drives the locking bolt to quickly lock the slitting seat and the slitting roller. This method eliminates the traditional manual alignment and repeated adjustment operations, realizes the automated and digital positioning of the slitting blade spacing, and significantly improves the adjustment efficiency and accuracy. It is particularly suitable for the multi-specification and multi-batch slitting production needs of agricultural biodegradable nonwoven fabrics.

[0015] 2. While improving the convenience and accuracy of adjustment, this invention enhances the functional adaptability and operational stability of the equipment. By adding a swing block and follower block mechanism controlled by a second cylinder, the angle of the slitting roller can be adjusted as a whole after the slitting knife is released, thereby changing the cutting angle of the slitting knife and adapting to the process requirements of slitting different materials and non-woven fabrics. In addition, the rubber buffer pads installed in the positioning groove further improve the stability and vibration resistance of the slitting seat installation, reduce displacement deviation during processing, ensure that the slitting lines are flat and burr-free, and have a reasonable overall structure and strong adaptability, which is conducive to improving production quality and equipment utilization.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the above description of the present invention, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is conventionally placed during use. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0023] Example 1 exist Figures 1-5In this invention, a technical solution is provided: an agricultural biodegradable nonwoven fabric slitting machine, including a receiving table 1 and a control box 2 fixed on its top. A slitting roller 3 is rotatably connected inside the control box 2. Positioning grooves 4 are evenly arranged on the outer side wall of the slitting roller 3 along the axial direction. The spacing between the positioning grooves 4 can be controlled according to the commonly used production spacing, which is convenient for actual adjustment. At the same time, a slitting seat 5 is threadedly connected inside one of the positioning grooves 4 by a locking bolt 6. A fastening head 7 is inserted inside the locking bolt 6. At this time, rotating the locking head 7 controls the rotation of the locking bolt 6, thereby connecting and fixing the slitting seat 5 with the corresponding positioning groove 4. Compared to existing technologies, to achieve automated control of the fastening head 7 before slitting to connect and fix the slitting seat 5 to the corresponding positioning groove 4, and to adjust the spacing between the slitting slices, a motor 8 is connected to the upper end of the fastening head 7. A lifting mechanism is connected to one side of the motor 8, and a horizontally moving translation mechanism is connected to one side of the lifting mechanism. A limit sleeve 9 is connected to one side of the motor 8 and is fitted onto one side of the slitting seat 5. During adjustment, the translation mechanism moves the limit sleeve 9 to a designated position above the slitting seat 5. Then, in conjunction with the lifting mechanism, the limit sleeve 9 is inserted into the outside of the slitting seat 5, thereby controlling the relative position of the relatively sliding slitting seat 5 and the slitting roller 3 to remain fixed. Then, in conjunction with the lifting mechanism and the rotation of the fastening head 7 at the output end of the motor 8 controller, the locking bolt 6 rotates and moves downward into the positioning hole 4, thereby installing the locking bolt 6 inside the positioning groove 4, completing the connection and fixation between the slitting seat 5 and the corresponding positioning groove 4, and also realizing the adjustment of the spacing between the slitting slices.

[0024] It also includes a discharge roller 21 and a take-up roller 22 respectively set on both sides of the slitting roller 3. The discharge roller 21 and the take-up roller 22 are rotatably installed inside the control box 2. One side of each of the multiple slitting seats 5 is connected to a slitting blade 15 by a first bolt. The motor 8 is moved up and down by the lifting mechanism, and the fastening head 7 inserted into the locking bolt 6 is rotated at the same time. Under the limit of the connecting block 10, the relative connection between the slitting roller 3 and the slitting seat 5 is quickly completed. The outer side wall of the limiting sleeve 9 is equipped with the connecting block 10. Both connecting blocks 10 are fixedly installed on the outer side wall of the motor 8.

[0025] In one aspect of this embodiment, the lifting mechanism is a first cylinder 11, and the output end of the first cylinder 11 is fixedly connected to the outer wall of the motor 8.

[0026] In one aspect of this embodiment, the translation mechanism includes a mounting base 12 fixedly installed at the bottom of the first cylinder 11. A lead screw 14 and a limiting rod 13 are symmetrically arranged inside the mounting base 12. The lead screw 14 is threaded into the interior of the mounting base 12, and the limiting rod 13 is slidably connected to the interior of the mounting base 12. Both the limiting rod 13 and the lead screw 14 are rotatably installed inside the control box 2. Rotation of the lead screw 14 controls the mounting base 12 to move horizontally under the action of the limiting rod 13, thereby driving the first cylinder 11 and the motor 8 to move horizontally according to the position of the positioning groove 4. How to achieve precise positioning relative to the positioning groove 4 is a matter of prior art and will not be discussed further here. One end of the lead screw 14 is fixedly connected to the first drive wheel 16, and the second drive wheel 17 is rotatably connected to one side inside the control box 2. The first drive wheel 16 and the second drive wheel 17 are connected by a rack and pinion belt drive. The rotation of the drive wheel is controlled by an external drive motor, thereby realizing the rotation of the lead screw 14.

[0027] In one aspect of this embodiment, one end of the slitting roller 3 passes through the control box 2 and is connected to a swing block 18. The end of the swing block 18 away from the slitting roller 3 is rotatably connected to a follower block 19. The lower end of the follower block 19 is rotatably connected to a second cylinder 20. One side of the second cylinder 20 is fixedly installed inside the control box 2. After the control fastening head 7 is disengaged from the positioning groove 4 and the slitting seat 5, the control second cylinder 20 pulls the follower block 19 and the swing block 18 downward, thereby controlling the slitting roller 3 to drive multiple slitting blades 15 to rotate and adjust the cutting angle of the slitting blades 15. The addition of the swing block 18 and follower block 19 mechanism controlled by the second cylinder 20 allows the overall angle of the slitting roller to be adjusted after the slitting blades 15 are released, thereby changing the cutting angle of the slitting blades 15 and adapting to the process requirements of slitting different materials and nonwoven fabrics.

[0028] In one aspect of this embodiment, buffer pads are provided below the inner walls of the multiple positioning grooves 4. The multiple buffer pads are made of rubber material. The buffer pads, together with the locking bolts 6, further improve the fixing effect of the slitting seat 5 and the slitting blade 15 relative to the slitting roller 3.

[0029] The working principle of this invention is as follows: In the preparation stage, the receiving platform 1 and the control box 2 are positioned, and the surface of the slitting roller 3 is evenly distributed with positioning grooves 4. According to the process sheet, the target spacing is input, and the second drive wheel 17 drives the first drive wheel 16 to rotate via the rack belt. The lead screw 14 drives the mounting base 12 to move along the limit rod 13, so that the motor 8 and the first cylinder 11 move laterally as a whole until the axis of the fastening head 7 coincides with the center of the corresponding positioning groove 4. The first cylinder 11 descends, the limit sleeve 9 covers the slitting seat 5, the motor 8 starts, and the fastening head 7 drives the locking bolt 6 to screw into the positioning groove 4. The slitting seat 5 and the slitting blade 15 are quickly locked, and the buffer pad absorbs the impact, completing a digital positioning without manual scale reference.

[0030] During the production stage, the discharge roller 21 feeds the fabric, which is then synchronously slit by the multi-component cutter 15. The agricultural biodegradable nonwoven fabric is precisely cut into the required strips and wound up by the take-up roller 22. If the cutting angle needs to be changed, the second cylinder 20 retracts, the follower block 19 pulls the swing block 18 down, the slitting roller 3 flips, and the cutting angle of the slitting blade 15 is adjusted in real time to adapt to different thicknesses and fiber orientations. When changing blades or widths, the first cylinder 11 lifts, the motor 8 reverses, the locking bolt 6 is released, and the translation mechanism moves to the next target positioning slot 4 again. The above actions are repeated. No manual measurement is required throughout the process, and the adjustment efficiency and accuracy are significantly improved.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
