Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a large-scale printing coil positioning and cutting equipment. Background Art

[0002] Large-scale printing coil positioning and cutting equipment is a kind of equipment used for precise cutting of large-scale printing coils, which is mainly used in textiles, packaging materials and wallpapers. The equipment realizes precise cutting of printed patterns through the coordinated work of coil unwinding system, pattern recognition and positioning system, cutting device, transmission system, tension control system, waste collection system, winding system and control system. The unwinding system ensures that the coil is smoothly unwound and cut by blade or laser.

[0003] When positioning and cutting large printed coils by blades, many printed coils are composed of fibers, fillers or other particles. The interlayer bonding of multi-layer composite materials is usually achieved by adhesives or physical pressing, and these bonding forces are not enough to resist the cutting stress. The pressure applied by the blade can easily cause interlayer separation, resulting in cracks at the interface and fine debris. This situation is particularly obvious when the composite material structure is complex, the number of layers is large or the bonding force is weak. In particular, multi-layer composite materials will have slight separation between the layers, resulting in fine debris at the incision. The debris will adhere to the cutting edge and the product surface, affecting the neatness and aesthetics of the product, especially for printed coils with high requirements on appearance. The edges will appear rough and unclean, and the debris will enter between the coil layers or adhere to the surface of the material, which will cause defects in the product and even affect its subsequent processing and use performance, such as affecting the bonding or packaging quality.

[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a large-scale printing coil positioning and cutting device, which has the following beneficial effects: 1. This large-scale printing coil positioning and cutting equipment uses a cleaning mechanism to turn on the blower. The air flow rate of the hollow sliding block is high, and the flow rate of the curved symmetrical pipe is low. According to the Venturi effect, the curved symmetrical pipe generates a suction force at this time.

Timely cleaning of accumulated debris avoids interference with the cutting process and subsequent processing, ensures cutting accuracy and product quality, and maintains the cleanliness and stable operation of the equipment. Regular replacement of filters reduces the wear of equipment components by debris, thereby extending the service life of the filter system and related components and reducing maintenance costs. The design of automatic replacement of filters reduces the frequency and difficulty of manual maintenance, optimizes the operating process, and makes the equipment more intelligent and efficient.

[0016] 3. This large-scale printing coil positioning cutting equipment uses a sharpening mechanism. During the rising process after cutting, the sharpening part can automatically contact the cutting knife and sharpen the knife to ensure that the blade always remains sharp. This reduces the frequency of manual maintenance and tool replacement, and improves the continuous working ability and cutting accuracy of the equipment. The sharpening function ensures that the blade of the cutting knife always remains sharp, reducing the uneven cutting caused by tool passivation, thereby reducing the generation of debris. A sharp knife can cut the material more smoothly, avoid tearing or crushing the material, and reduce the generation of debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The cutting mechanism 3 includes a telescopic motor 31, the output shaft of the telescopic motor 31 is fixedly connected to a pressing connection sleeve 32, the bottom of the pressing connection sleeve 32 is fixedly connected to a cutting knife 33, the telescopic motor 31 is fixedly connected to the positioning cutting device 1, and the blade of the cutting knife 33 is inclined. The inclined blade can gradually cut into the material, reduce the instantaneous cutting resistance, make the cutting smoother, reduce the wear of the tool, and can reduce the movement or tearing of the material during the cutting process, ensure that the incision is smoother, thereby improving the cutting accuracy. The positioning cutting device 1 is turned on, so that the large printing coil is transported to the position of the cutting mechanism 3, and the telescopic motor 31 is turned on to drive the pressing connection sleeve 32 and the cutting knife 33 to cut the coil downward.

[0022] The cleaning mechanism 4 includes a blade parallel slide 41, which is arranged on the inner wall of the cutting knife 33, a fixed slide block 42 is fixedly connected to the outer wall of the positioning and cutting device 1, a blower 43 is fixedly connected to the outer wall of the positioning and cutting device 1, one end of an air intake telescopic duct 44 is fixedly connected to the outer wall of the blower 43, a hollow sliding block 45 is fixedly connected to the other end of the air intake telescopic duct 44, a curved symmetrical duct 46 is fixedly connected to the bottom of the hollow sliding block 45, one end of an exhaust telescopic duct 47 is fixedly connected to the outer wall of the hollow sliding block 45, the other end of the exhaust telescopic duct 47 is fixedly connected to the outer wall of the positioning and cutting device 1, one end of a spring 48 is fixedly connected to the top of the hollow sliding block 45, and the spring 48 is fixedly connected to the outer wall of the positioning and cutting device 1. 8 is fixedly connected to a connecting square block 49, and an outer wall of the hollow sliding block 45 is fixedly connected to one end of a telescopic column 410, and the other end of the telescopic column 410 is fixedly connected to the outer wall of the connecting square block 49. The blade parallel slide groove 41 is parallel to the blade of the cutting knife 33, that is, the blade parallel slide groove 41 is not parallel to the horizontal plane, but is inclined. This makes the blade parallel slide groove 41 exert a lateral force on the hollow sliding block 45 when the cutting knife 33 moves downward. The two sides of the hollow sliding block 45 are rectangular parallelepipeds, and the middle part of the hollow sliding block 45 is a cylinder. The cylinder in the middle part of the hollow sliding block 45 passes through the inner wall of the blade parallel slide groove 41, and the outer wall of the connecting square block 49 is slidably connected to the inner wall of the fixed slide groove block 42. Turn on the blower 43 to drive the outside air to pass through the air intake telescopic duct 44, the hollow sliding block 45, and the exhaust telescopic duct 47 in sequence. At this time, the air flow rate of the hollow sliding block 45 is high, and the flow rate of the curved symmetrical duct 46 is low. According to the Venturi effect, the curved symmetrical duct 46 generates a suction force at this time, so that the debris generated by the cutting of the cutting knife 33 is adsorbed, and when the cutting knife 33 moves downward for cutting, since the blade of the cutting knife 33 is set at an angle, the position of the cutting knife 33 and the cutting point of the coil is moved horizontally. At this time, the blade parallel slide groove 41 on the cutting knife 33 generates a vertical downward force on the hollow sliding block 45 and a lateral force at the same time, so that the hollow sliding block 45 moves closely with the position of the cutting point of the inclined blade of the cutting knife 33, and the debris generated by the cutting knife 33 is timely adsorbed.

[0023] The filtering mechanism 5 includes a sealed telescopic pipe 51, one end of which is fixedly connected to the inner wall of the hollow sliding block 45, and the other end of the sealed telescopic pipe 51 is fixedly connected to a hollow square pressing frame 52, and the outer wall of the hollow square pressing frame 52 is fixedly connected to one end of a spring 2 53, and the other end of the spring 2 53 is fixedly connected to the inner wall of the hollow sliding block 45. A positive filter element 54 is connected to the piston on the inner wall of the hollow sliding block 45, and a discharge element 55 is fixedly connected to the bottom of the hollow sliding block 45. One end of a spring 3 56 is fixedly connected to the bottom of the hollow sliding block 45, and the other end of the spring 3 56 is fixedly connected to a contact plate 57, and the top of the contact plate 57 is fixedly connected to a connecting rod 58, and the top of the hollow sliding block 45 is fixedly connected to a storage basket 59, and the inner wall of the storage basket 59 is fixedly connected to the storage basket 59. One end of spring four 510 is fixedly connected, and the other end of spring four 510 is fixedly connected to a pressing plate 511, a spare filter element 512 is placed in the storage basket 59, a recessed groove 513 is provided on the inner wall of the hollow sliding block 45, one end of spring five 514 is fixedly connected to the inner wall of the recessed groove 513, and the other end of the spring five 514 is fixedly connected to an arc-shaped limit block 515, the outer wall of the hollow square pressing frame 52 is piston-connected to the inner wall of the hollow sliding block 45, the outer wall of the connecting rod 58 is slidably connected to the hollow sliding block 45, a through groove is provided on the top of the storage basket 59 for inserting and placing the spare filter element 512, the outer wall of the pressing plate 511 is slidably connected to the inner wall of the storage basket 59, and the outer wall of the arc-shaped limit block 515 is slidably connected to the inner wall of the recessed groove 513 and the outer wall of the hollow sliding block 45. After the debris enters the hollow sliding block 45 through the curved symmetrical pipe 46, it accumulates on the surface of the positive filter 54. When the debris on the surface of the positive filter 54 accumulates to a certain extent, the resistance it encounters increases, causing the positive filter 54 to move leftward, against the hollow square pressing frame 52 to press the spring 2 53 to the left, until the positive filter 54 moves leftward to the position of the discharge member 55, and is discharged along the discharge member 55 under the action of gravity, and the positive filter 54 presses downward against the contact plate 57, and the contact plate 57 drives the positive filter 54 to move leftward. The connecting rod 58 moves downward, and the connecting rod 58 resists a spare filter element 512 from moving downward, so that the spare filter element 512 overcomes the resistance of the arc-shaped limit block 515, so that the arc-shaped limit block 515 compresses the spring five 514 and retracts it into the recessed groove 513. At this time, the spare filter element 512 falls downward into the hollow sliding block 45 and is replaced by the positive filter element 54. After the previous positive filter element 54 moves downward for a certain distance, it falls in the direction away from the spring three 56 under the action of the inclined surface at the top of the contact plate 57.

[0024] The sharpening mechanism 6 includes a fixed guide block 61, the outer wall of the fixed guide block 61 is fixedly connected to the outer wall of the hollow sliding block 45, the outer wall of the fixed guide block 61 is provided with a square opening groove 62, the outer wall of the fixed guide block 61 is fixedly connected to one end of a spring 63, the other end of the spring 63 is fixedly connected to a triangular block 64, the outer wall of the triangular block 64 is fixedly connected to a guide connecting strip 65, the bottom of the guide connecting strip 65 is fixedly connected to one end of a spring 7 66, the other end of the spring 7 66 is fixedly connected There is a sharpening piece 67, the top of the sharpening piece 67 is fixedly connected to a vertical strip piece 68, one end of a spring eight 69 is fixedly connected to the inner wall of the guide connecting strip 65, the other end of the spring eight 69 is fixedly connected to a trapezoidal piece 610, the outer wall of the positioning and cutting device 1 is fixedly connected to a release connecting strip 611, the outer wall of the positioning and cutting device 1 is fixedly connected to an arc-shaped connecting strip 612, the outer wall of the vertical strip piece 68 is slidably connected to the inner wall of the guide connecting strip 65, and the outer wall of the trapezoidal piece 610 is slidably connected to the inner wall of the guide connecting strip 65.

[0025] To sum up, when the large printing coil positioning and cutting device is used, the positioning and cutting device 1 is turned on so that the large printing coil is conveyed to the position of the cutting mechanism 3, and the telescopic motor 31 is turned on to drive the pressing connection sleeve 32 and the cutting knife 33 to cut the coil downward.

[0026] At this time, the blower 43 is turned on to drive the outside air to pass through the air intake telescopic pipe 44, the hollow sliding block 45, and the exhaust telescopic pipe 47 in sequence. At this time, the air flow rate of the hollow sliding block 45 is high, and the flow rate of the curved symmetrical pipe 46 is low. According to the Venturi effect, the curved symmetrical pipe 46 generates a suction force, so that the debris generated by the cutting of the cutting knife 33 is adsorbed. When the cutting knife 33 moves downward for cutting, since the blade of the cutting knife 33 is inclined, the position of the cutting point of the cutting knife 33 and the coil is moved horizontally. At this time, the blade parallel slide groove 41 on the cutting knife 33 generates a vertical downward force on the hollow sliding block 45 and generates a horizontal force, so that the hollow sliding block 45 moves closely with the position of the cutting point of the inclined blade of the cutting knife 33, and timely adsorbs the debris generated by the cutting knife 33. Through the cooperation of the Venturi effect and the inclined blade, the suction force generated can effectively adsorb the debris generated during the cutting process. This can prevent debris from accumulating in the cutting area, reducing its impact on cutting accuracy and product quality, while keeping the equipment clean and preventing debris from affecting subsequent processing steps. The mechanism of absorbing debris helps to reduce the accumulation of debris in the cutting area, which can reduce the friction and impact between the tool and the debris, reduce tool wear, and extend the service life of the tool. The timely absorption and cleaning of debris can reduce the need for manual cleaning, while ensuring that the cutting process is not disturbed, improving the working efficiency and production speed of the equipment.

[0027] When the debris enters the hollow sliding block 45 through the curved symmetrical pipe 46, it accumulates on the surface of the positive filter 54. When the debris on the surface of the positive filter 54 accumulates to a certain extent, the resistance it encounters increases, causing the positive filter 54 to move leftward, against the hollow square pressing frame 52 to press the spring 2 53 to the left, until the positive filter 54 moves leftward to the position of the discharge member 55, and is discharged along the discharge member 55 under the action of gravity, and the positive filter 54 presses downward against the contact plate 57, and the contact plate 57 drives the connecting rod 58 to move downward, and the connecting rod 58 presses against a spare filter 51 2 moves downward, so that the spare filter 512 overcomes the resistance of the arc-shaped limit block 515, so that the arc-shaped limit block 515 compresses the spring five 514 and shrinks into the recessed groove 513. At this time, the spare filter 512 falls downward into the hollow sliding block 45 and is replaced by the positive filter 54. The previous positive filter 54 moves downward for a certain distance and falls in the direction away from the spring three 56 under the action of the inclined surface on the top of the contact plate 57. A receiving frame can be set to receive the fallen positive filter 54. This reciprocating cycle allows the adsorbed debris to be well filtered and will not block the pipeline. By automatically replacing the filter, the pipeline blockage caused by the accumulation of debris is avoided, the air circulation system is ensured to be always unobstructed, and the possibility of fault shutdown is reduced. The automated filtering and replacement mechanism reduces the need for manual maintenance, allowing the equipment to continue to operate efficiently without interruption, thereby improving production efficiency. Timely cleaning of accumulated debris avoids interference of debris with the cutting process and subsequent processing, ensures cutting accuracy and product quality, and maintains the cleanliness and stable operation of the equipment. Regular replacement of filters reduces the wear of debris on equipment components, thereby extending the service life of the filtration system and related components and reducing maintenance costs. The design of automatic replacement of filters reduces the frequency and difficulty of manual maintenance, optimizes the operating process, and makes the equipment more intelligent and efficient.

[0028] Then, when the cutting knife 33 cuts downward, the hollow sliding block 45 moves in the direction of the arc-shaped connecting strip 612 until the cutting is completed. At this time, the arc-shaped connecting strip 612 contacts the triangular block 64, so that the triangular block 64 drives the guide connecting strip 65 to move in the direction of the cutting knife 33, so that the guide connecting strip 65 drives the vertical strip 68 to move in the direction of the cutting knife 33, and the vertical strip 68 drives the sharpening member 67 to move in the direction of the cutting knife 33 until the sharpening member 67 contacts the cutting knife 33. At this time, the trapezoidal member 610 is clamped with the square opening groove 62 under the action of the spring eight 69, and the sharpening member 67 moves downward under the action of the spring seven 66, so that it fits the cutting more closely. The blade of the knife 33, at this time, the cutting knife 33 returns upward, and the cutting knife 33 drives the blade parallel to the slide groove 41 to apply a lateral opposite force to the hollow sliding block 45 so that the hollow sliding block 45 moves in the direction of the release connection strip 611. At this time, the sharpening member 67 and the blade of the cutting knife 33 rub against each other to sharpen the knife, until the release connection strip 611 passes through the square opening groove 62 and hits the trapezoidal member 610, so that the trapezoidal member 610 is in contact with the square opening groove 62 and is engaged, and under the action of the spring 63, the triangular block 64 and the guide connection strip 65 are driven to return, and the guide connection strip 65 drives the vertical strip 68 and the sharpening member 67 to return, so as to avoid the cutting knife 33 from colliding with the sharpening member 67 when cutting downward. In the process of rising after cutting, the sharpening member 67 can automatically contact with the cutting knife 33 and sharpen the knife to ensure that the blade always remains sharp. This reduces the frequency of manual maintenance and tool replacement, and improves the continuous working ability and cutting accuracy of the equipment. The sharpening function ensures that the blade of the cutting knife 33 always remains sharp, reducing uneven cutting caused by blunting of the knife, thereby reducing the generation of debris. A sharp knife can cut the material more smoothly, avoid tearing or crushing the material, and reduce the generation of debris.
