Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric cutting device. Background Art

[0002] Non-woven fabric is a kind of fabric that does not require spinning and weaving. It is made by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric has the characteristics of water-retaining, breathable, flexible, non-toxic and non-irritating, which makes it an environmentally friendly material. Non-woven fabrics usually need to be cut during processing, so special cutting devices are used.

[0003] A Chinese utility model patent with the announcement number CN220394143U discloses a cutting device for non-woven fabric production. The device starts a cylinder, which drives a fixing plate to move downward, so that the non-woven fabric can be fixed. The ion fan can remove static electricity on both sides of the cut edge of the non-woven fabric to prevent the non-woven fabric from rolling up or becoming uneven. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the non-woven fabric needs to be fixed first, and then the cutting knife is controlled to approach the non-woven fabric, which not only reduces the cutting efficiency of the non-woven fabric, but also increases the energy consumption of the device. At the same time, the device uses an ion fan to remove static electricity from the non-woven fabric to prevent it from wrinkling, which further increases the energy consumption of the device. For this reason, we provide a non-woven fabric cutting device. Utility Model Content

[0005] In order to solve the problems of low cutting efficiency and high energy consumption of the device in the above background technology, the utility model provides a non-woven fabric cutting device.

[0006] The utility model is implemented by the following technical scheme: a non-woven fabric cutting device, comprising:

[0007] A cutting table, wherein an electric push rod is fixedly connected to the cutting table through a connecting frame, a telescopic end of the electric push rod is fixedly connected to a connecting plate, a bottom of the connecting plate is fixedly connected to a moving groove through a bracket, a screw rod is rotatably connected inside the moving groove, a motor is fixedly connected to one side of the moving groove, and a rotor end of the motor is coaxially fixedly connected to one end of the screw rod, a moving block is connected to the external thread of the screw rod, and a cutting knife is fixedly connected to the bottom of the moving block;

[0008] An automatic clamping assembly, which includes two groups of fixed frames symmetrically fixedly connected to the top of the cutting table, a pressure plate being horizontally arranged on the inner side surface of the fixed frame, a vertical rod one being symmetrically fixedly connected to the top of the pressure plate and the vertical rod one is slidably connected to the fixed frame, a spring one is sleeved on the outside of the vertical rod one, the top ends of the two groups of vertical rods one are fixedly connected to the same strip plate one, a strip frame is fixedly connected to the top center of the strip plate one, a cross bar is movably connected to the inner side surface of the strip frame and the cross bar is fixedly connected to the connecting plate, and magnet sheets are fixedly connected to the top of the fixed frame and the bottom of the strip plate one.

[0009] As a further improvement of the above scheme, sliding rods are symmetrically and fixedly connected to both sides of the top of the cutting table, and the two groups of sliding rods on the same side are slidably connected to the same slide board outside, and a leveling roller is rotatably connected to the bottom of the slide board through a connecting seat, and a vertical rod two is symmetrically and fixedly connected to the top of the connecting seat, and the vertical rod two is slidably connected to the slide board on the same side, and a spring two is sleeved on the outside of the vertical rod two, and the top of the two groups of vertical rods on the same side are fixedly connected to the same strip plate two, and rollers are rotatably connected to both sides of the strip plate two, and guide blocks of a right-angled trapezoidal structure are symmetrically and fixedly connected to both sides of the cutting table, and a connecting rod is hinged between the slide board and the strip plate one on the same side through a hinge.

[0010] As a further improvement of the above solution, two ends of the spring 1 are fixedly connected to the pressure plate and the fixing frame respectively.

[0011] As a further improvement of the above solution, the end of the cross bar is fixedly connected to a limiting plate.

[0012] As a further improvement of the above solution, the magnetic pole directions of the facing surfaces of the two groups of magnet pieces are arranged in opposite directions.

[0013] As a further improvement of the above solution, two ends of the second spring are fixedly connected to the connecting seat and the slide plate respectively.

[0014] As a further improvement of the above solution, a cutting groove is provided at the top center of the cutting table.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the process of pushing the cutting knife to move vertically downward by the electric push rod, the utility model can drive two sets of cross bars to move on the inner sides of their respective strip frames. When the cross bars contact the bottom of the inner sides of the strip frames, the strip plates can be pressed down. When the strip plates are pressed, they will push the pressing plates to move downward, so that the two sides of the cutting position of the non-woven fabric can be automatically pressed down and fixed to prevent it from moving during cutting, thereby ensuring the flatness of the non-woven fabric incision, which not only improves the cutting efficiency of the non-woven fabric, but also reduces the energy consumption of the device, and has strong practicality.

[0017] 2. In the process of vertical downward movement of the strip plate 1, the utility model utilizes the hinge effect between the strip plate 1 and the slide plate and the connecting rod, and the sliding cooperation between the slide plate and the slide rod, so that the slide plate can be pushed to slide to the other side of the slide rod. At this time, the roller will roll on the guide block. When the roller rolls away from the guide block, under the rebound action of the spring 2, the leveling roller can automatically press on the surface of the non-woven fabric, and as the strip plate 1 continues to move downward, the two sets of leveling rollers can be pushed to continue to roll to both sides at the same time, so that the non-woven fabric can be automatically leveled, further reducing the energy consumption of the device and improving the cutting efficiency of the non-woven fabric.

[0018] 3. The utility model can drive the cross bar to move vertically upward in the process of resetting the cutting knife after cutting is completed. Due to the adsorption effect between the two groups of magnet sheets, the pressure plate is still pressed on the surface of the non-woven fabric at this time, thereby avoiding the problem of adhesion between the cutting knife and the non-woven fabric. When the cross bar moves to the top of the inner side of the strip frame, it will pull the strip frame to move together. At this time, the two groups of magnet sheets will separate. The rebound effect of spring 1 can make the pressure plate automatically reset to automatically release the non-woven fabric, further improving the practicability of the device.

[0030] Both sides of the top of the cutting table 1 are symmetrically fixedly connected with sliding rods 201, the outside of the two groups of sliding rods 201 on the same side are slidably connected with the same slide plate 202, and the bottom of the slide plate 202 is rotatably connected with a leveling roller 203 through a connecting seat, the top of the connecting seat is symmetrically fixedly connected with a vertical rod 204, and the vertical rod 204 is slidably connected to the slide plate 202 on the same side, and the vertical rod 204 is slidably connected to the slide plate 202 on the same side, and the outside of the vertical rod 204 is provided with a spring 205, and the two ends of the spring 205 are respectively fixedly connected to the connecting seat and the slide plate 202, and the top of the two groups of vertical rods 204 on the same side are fixedly connected with the same strip plate 206, and both sides of the strip plate 206 are rotatably connected with rollers 207, and both sides of the cutting table 1 are symmetrically fixedly connected with guide blocks 208 of a right-angled trapezoidal structure, and a connecting rod 209 is hinged between the slide plate 202 on the same side and the strip plate 1 104 through a hinge.

[0031] The implementation principle of a non-woven fabric cutting device in the embodiment of the present application is as follows: first, the non-woven fabric is laid on the cutting table 1 and the position to be cut is located at the cutting groove, and then the electric push rod 2 is started, and the connecting plate 3 is pushed vertically downward by the electric push rod 2, so that the cutting knife 7 can be pushed downward together, and the connecting plate 3 can also drive the two sets of cross bars 106 to move downward together during the vertical downward movement. When the cross bar 106 moves to the bottom of the inner side surface of the strip frame 105, the connecting plate 3 continues to move downward, so that the cross bar 106 can press down the strip plate 104. After the strip plate 104 is pressed, it will push the pressure plate 101 downward, and at this time the spring 103 will When the cutting knife 7 is lowered to the inside of the cutting groove, the pressing plate 101 also presses and fixes the two sides of the non-woven fabric to be cut. At the same time, in the process of the vertical downward movement of the strip plate 104, the hinge between the strip plate 104 and the slide plate 202 and the connecting rod 209, and the sliding cooperation between the slide plate 202 and the slide bar 201 are utilized to push the slide plate 202 to slide to the other side of the slide bar 201. At this time, the roller 207 will roll on the guide block 208. When the roller 207 rolls off the guide block 208, the spring 205 rebounds and the leveling roller 203 can automatically press against the surface of the non-woven fabric. , and as the strip plate 104 continues to move downward, it can push the two sets of leveling rollers 203 to continue to roll to both sides at the same time, so that the non-woven fabric can be automatically leveled, and then the motor is started, and the motor drives the screw rod 5 to rotate, so that it can drive the moving block 6 to slide horizontally inside the moving groove 4, and the moving block 6 moves to drive the cutting knife 7 to move, so that the non-woven fabric can be cut, and then the cutting knife 7 is driven to reset by the electric push rod 2. In the process of driving the cutting knife 7 to reset, it can drive the cross bar 106 to move vertically upward together. Due to the adsorption effect between the two sets of magnet sheets 107, the pressing plate 101 is still pressed on the surface of the non-woven fabric at this time. Thereby, the problem of adhesion between the cutting knife 7 and the non-woven fabric is avoided. When the cross bar 106 moves to the top of the inner side of the strip frame 105, it will pull the strip frame 105 to move together. At this time, the two groups of magnet sheets 107 will be separated. The rebound effect of the spring 103 can make the pressure plate 101 automatically reset to automatically release the non-woven fabric. At the same time, in the process of driving the cutting knife 7 to reset, the leveling roller 203 will also be automatically reset. When the roller 207 rolls to the surface of the guide block 208, the spring 205 will be compressed. At this time, the leveling roller 203 will also automatically leave the surface of the non-woven fabric, and finally the non-woven fabric can be removed.

[0033] This embodiment is further improved on the basis of the embodiment 1 in that the end of the cross bar 106 is fixedly connected to a limiting plate, which can prevent the cross bar 106 from being separated from the bar frame 105 .

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
