Description

Technical Field

[0001] The invention relates to the technical field of material collection and uncollecting of printing machines, in particular to a static electricity elimination auxiliary material collection and uncollecting mechanism for a gravure printing machine. Background Art

[0002] A gravure printing press is a machine that uses a gravure plate for printing. The image and text part of the printing plate of a gravure printing press is concave, while the blank part is on the same plane as the outer circle of the printing plate cylinder. When printing, the entire surface of the printing plate is coated with ink, and then a special scraper mechanism is used to remove the ink in the blank part, so that the ink only remains in the mesh cells of the image and text part. Under the action of greater pressure, the ink is transferred to the surface of the substrate to obtain a printed product. During printing, the paper needs to be retracted and released through an auxiliary mechanism, but static electricity will be generated during the process of retracting and releasing the paper, resulting in burrs, missing prints, flowery spots, and streaks on the paper during the printing process, affecting the printing quality.

[0003] The patent with announcement number CN208413177U discloses a gravure printing machine static elimination auxiliary material collection and unloading mechanism, which includes a main support arm, a connecting fixed shaft, a material collection roller and a material discharge roller. The two ends of the connecting fixed shaft are respectively provided with main support arms through a second connecting plate, a material discharge roller is provided at one end between the two main support arms, and a material collection roller is provided at the other end. The main support arm is located at one end of the material collection roller and is provided with an assembly groove. The end of the material collection roller is fixed in the assembly groove through a bearing seat and a fastening bolt. The device has a simple structure and low cost. It can realize winding, unwinding and unloading, and placing other material coils. At the same time, it can eliminate static electricity during use to avoid the influence of static electricity on printing. Although the patent solves the above problems, it still has the problem that it takes a long time to wait for static electricity to be released by eliminating static electricity through the elimination line, and the efficiency of static electricity removal is low. Therefore, an gravure printing machine static elimination auxiliary material collection and unloading mechanism is proposed to solve the above problems. Summary of the invention

When the device is stored for a long time, a through hole is opened to avoid dust accumulation on the surface of the mechanism. The dust falls from the through hole to between the upper half roller and the lower half roller and is absorbed by the arc-shaped activated carbon plate. The motor is started, and the motor drives the main shaft to rotate, and the main shaft drives the tubular screw to rotate, and the tubular screw drives the transmission nut to move back and forth left and right, and the transmission nut drives the limit push plate 1 and the limit push plate 2 to move back and forth left and right, and the limit push plate 1 and the limit push plate 2 push the arc-shaped The connecting frame slides back and forth on the limit sliding bar, and the arc-shaped connecting frame drives the arc-shaped activated carbon plate to move back and forth.

After the ion wind rod is started, the static electricity of the mechanism is eliminated through the through holes opened on the upper and lower material collection rollers, so as to avoid the paper being affected by static electricity during the material collection and unloading process, thereby causing burrs, missing prints, flowery spots, and streaks, resulting in a decrease in printing quality. The ion wind rod and the mounting block are lifted and separated from the card slot mounting seat, and then the ion wind rod is quickly disassembled from the mechanism for maintenance and repair, which increases the service life of the ion wind rod. The plug block and the triangular card block are stuck in the card slot mounting seat, so that the ion wind rod can be quickly installed on the mechanism, which improves the convenience of use.

[0009] 2. The gravure printing machine has an auxiliary material collection and unloading mechanism for static elimination. Dust falls from the through-holes between the upper and lower material collection rollers and is absorbed by the arc-shaped activated carbon plate, which prevents dust from accumulating on the surface of the mechanism and attracting static electricity to generate static electricity accumulation, making static electricity removal more convenient. When the arc-shaped activated carbon plate moves back and forth left and right, it increases the contact area of ​​the adsorbed air, thereby adsorbing dust more quickly and improving the adsorption efficiency. The arc-shaped cleaning brush sweeps away the dust adhered to the through-holes during movement, which prevents dust from clogging the through-holes and causing dust to accumulate on the surface of the mechanism and unable to enter between the upper and lower material collection rollers, thereby improving the adsorption effect of the arc-shaped activated carbon plate and the surface cleaning effect of the device.

[0010] 3. The gravure printing machine has an electrostatic elimination auxiliary material collection and unloading mechanism. The solid dehumidifier in the placement cylinder dehumidifies the air between the upper and lower material collection rollers, and the solid dehumidifier dehumidifies the air near the surfaces of the upper and lower material collection rollers through the through holes to prevent the mechanism from getting damp and to prevent the paper from getting wet and affecting the printing quality. The placement cylinder moves back and forth left and right, which increases the contact area of ​​the placement cylinder with the air and the dehumidification efficiency of the solid dehumidifier. The push plate stirs the solid dehumidifier in the placement cylinder when it rotates, which increases the contact efficiency between the solid dehumidifier and the air, and further improves the dehumidification efficiency and the printing effect of the paper.

The upper half roller 71 and the lower half roller 72 are separated and repaired and replaced to avoid the aging of the upper half roller 71 and the lower half roller 72 during long-term use, resulting in a decrease in the material collection efficiency. After the wind rod 74 is started, the mechanism is destaticized through the through holes opened on the upper and lower receiving rollers 71 and 72 to prevent the paper from being affected by static electricity during the process of collecting and releasing materials, thereby causing burrs, missing prints, flowery spots, streaks and other phenomena that lead to a decrease in printing quality. The front side of the main beam 1 is provided with a mechanism surface cleaning device 8 for absorbing and removing dust and impurities on the surface of the receiving mechanism to prevent static electricity from being easily generated on the surface of the receiving mechanism due to excessive dust.

[0015] Working principle: Turn the screw to separate the fixing plates 73 on both sides of the upper and lower rollers 71 and 72, so that the upper and lower rollers 71 and 72 can be separated, and then the upper and lower rollers 71 and 72 can be repaired and replaced to avoid the aging of the upper and lower rollers 71 and 72 during long-term use, which will lead to a decrease in the material collection efficiency. Before collecting the materials, insert the wires into the ion wind rod 74 through the sockets 1, 2 and 3 to energize the ion wind rod 74. After the ion wind rod 74 is started, The through holes on the upper receiving roller 71 and the lower receiving roller 72 are used to remove static electricity from the mechanism to prevent the paper from being affected by static electricity during the process of receiving and releasing the material, thereby causing burrs, missing prints, flowery spots, streaks and other phenomena that lead to a decrease in printing quality. The toggle block 712 is pushed to the side away from the ion wind rod 74, and the toggle block 712 drives the trapezoidal clamping block 79 to slide in the card slot mounting seat 75 away from the insertion block 77.

When the plug block 77 and the triangular clamping block 78 are fully inserted into the slot mounting seat 75, the elastic reset action of the elastic telescopic rod 710 drives the trapezoidal clamping block 79 to elastically reset to the side close to the plug block 77, thereby clamping the plug block 77 and the triangular clamping block 78 in the slot mounting seat 75, so that the ion wind rod 74 can be quickly installed on the mechanism, which improves the convenience of use.

During the movement, the arc-shaped cleaning brush 89 sweeps away the dust adhering to the through hole to prevent the through hole from being blocked by dust, resulting in dust accumulation on the surface of the mechanism and being unable to enter between the upper half roller 71 and the lower half roller 72 for collecting materials, thereby improving the adsorption effect of the arc-shaped activated carbon plate 84 and the surface cleaning effect of the device, and the upper half roller 71 and the lower half roller 72 for collecting materials are respectively connected by the limiting slide bar 81 and the arc-shaped connecting frame 83, and when the upper half roller 71 and the lower half roller 72 for collecting materials are separated, the arc-shaped connecting frame 83 can be directly driven to separate.

At the end of the supporting connecting rod 94 away from the inner wall of the placing cylinder 92, the rotating rod 96 is rotatably connected to the inner surface of the transmission connecting plate 91, the roller 97 is fixedly connected to the circumferential surface of the rotating rod 96, the connecting plate 98 is fixedly connected to the front and rear sides of the mounting block 76, the slide rail 99 is fixedly connected to the end of the connecting plate 98 away from the mounting block 76, the pushing plate 910 is fixedly connected to the circumferential surface of the rotating rod 96, the transmission connecting plate 91 and the right side of the limiting push plate 88 are fixedly connected, the rotating rod 96 and the inner surface of the rotating ring 95 are rotatably connected, the circumferential surface of the rotating rod 96 and the inner surface of the sealing cylinder cover 93 are in contact with each other, the circumferential surface of the roller 97 and the inner surface of the slide rail 99 are in contact with each other, the placing cylinder 92 reciprocates left and right, which increases the contact area of ​​the air of the placing cylinder 92 and the dehumidification efficiency of the solid dehumidifier. When the pushing plate 910 rotates, it stirs the solid dehumidifier in the placing cylinder 92, improves the contact efficiency between the solid dehumidifier and the air, and further improves the dehumidification efficiency and the printing effect of the paper.

[0019] Working principle: Rotate the sealing cylinder cover 93 to separate the sealing cylinder cover 93 from the placing cylinder 92, put the solid dehumidifier into the placing cylinder 92 through the gap between the sealing cylinder cover 93 and the placing cylinder 92, and then rotate the sealing cylinder cover 93 in the opposite direction to connect the sealing cylinder cover 93 and the placing cylinder 92, thereby sealing the placing cylinder 92. At this time, the solid dehumidifier in the placing cylinder 92 dehumidifies the air between the upper half roller 71 and the lower half roller 72 of the receiving material, and the solid dehumidifier dehumidifies the air near the surface of the upper half roller 71 and the lower half roller 72 of the receiving material through the through hole to prevent the mechanism from being damp and to prevent the paper from being wet and affecting the printing quality. The limit push plate 1 87 and the limit push plate 2 88 move back and forth left and right When the placement cylinder 92 reciprocates left and right, it drives the transmission connecting plate 91 to move back and forth, and then drives the placement cylinder 92 to move back and forth, thereby increasing the contact area of ​​the placement cylinder 92 with the air and improving the dehumidification efficiency of the solid dehumidifier. When the placement cylinder 92 reciprocates left and right, it drives the rotating rod 96 to move back and forth. The rotating rod 96 drives the roller 97 to slide back and forth in the slide rail 99. The friction between the roller 97 and the slide rail 99 causes rotation. The rotation of the roller 97 drives the rotating rod 96 to rotate. The rotating rod 96 drives the pushing plate 910 to rotate. When the pushing plate 910 rotates, it stirs the solid dehumidifier in the placement cylinder 92, thereby increasing the contact efficiency between the solid dehumidifier and the air, and further improving the dehumidification efficiency and the printing effect of the paper.
