It adopts round-to-round direct printing method for printing.

[0003] Patent announcement number CN214269139U discloses a conveying structure of a decorative paper gravure printing machine. The conveying structure of the decorative paper gravure printing machine includes: a bottom plate; an adjustment slot, the adjustment slot is opened on the top of the bottom plate; an adjustment motor, the adjustment motor is fixedly installed in the adjustment slot; an adjustment screw, the adjustment screw is fixedly installed on the output shaft of the adjustment motor, and the end of the adjustment screw away from the adjustment motor is rotatably connected to the inner wall of one side of the adjustment slot; a moving plate, the moving plate is threadedly installed on the adjustment screw, and the top of the moving plate extends to the top of the adjustment slot. The conveying structure of the decorative paper gravure printing machine provided by this patent has the advantages of simple operation, convenient movement, and automatic adjustment of height and angle.

[0004] However, the device still has some shortcomings: the device can freely adjust the height and angle to improve practicality, but after the height is raised, the center of gravity increases, causing the slight vibration generated by the equipment during operation to be amplified synchronously, resulting in reduced stability of the transmission roller for conveying the film material, thereby increasing the possibility of the film material deviating from the center range of the transmission roller, resulting in reduced printing quality. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a transmission structure of a gravure printing machine, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a conveying structure of a gravure printing machine, comprising a base, a moving assembly is arranged at the bottom of the base, a fixed plate is arranged at the center of the top of the base, a center roller is arranged above the inside of the fixed plate, a supporting assembly is arranged on the right side of the top of the base, and a conveying roller is arranged inside the supporting assembly; An anti-wave device is provided on the left side of the top of the base, an anti-pollution device is provided inside the anti-wave device, and an anti-wrinkle device is provided on the left side of the anti-wave device; The anti-wave device comprises an electric telescopic rod, the bottom of which is fixedly mounted on the left side of the top of the base, a bearing plate is fixedly mounted on the top of the telescopic end of the electric telescopic rod, the bearing plate is located on the left side of the fixed plate, and a motor is arranged on the front of the bearing plate, a transmission rod is rotatably mounted inside the bearing plate, one end of the front of the transmission rod passes through and is fixedly mounted on the back of the motor output end, a transmission roller is passed through and fixedly mounted on the outer wall of the transmission rod, a pressure roller is rotatably mounted on the top of the bearing plate, the pressure roller is located above the transmission roller, a telescopic limit plate is fixedly mounted on the bottom of one end of the bearing plate close to the fixed plate, and the telescopic limit plate is fixed The bottom of the end is fixedly installed on the top of the base, the bottom of the carrying plate is hinged with an inclined plate, the bottom of the inclined plate is hinged with a rubber plate, the inside of the rubber plate is penetrated by a spring and an arc-shaped soft plate is slidably installed, an L-shaped plate is fixedly installed on the side of the rubber plate close to the electric telescopic rod, and the side of the rubber plate close to the L-shaped plate is hinged with a vertical plate through a torsion spring. The base is conveniently moved to the required transmission direction through the moving component, and the motor is started. When the electric output end rotates, it drives the transmission rod to rotate. When the transmission rod rotates along the inner wall of the carrying plate, it drives the transmission roller to rotate, and the film material is inserted between the transmission roller and the pressure roller. Under the rotation and transportation of the transmission roller, the film material is transported to the right and frictionally. At the bottom of the outer wall of the pressure roller, the pressure roller starts to rotate in the same direction as the transmission roller through friction. Then the top of the film material is stretched to the bottom of the center roller and then stretched upward until the bottom of the film material contacts the top of the conveying roller to form a conveying process. When the transmission height of the transmission roller needs to be adjusted, the electric telescopic rod is started, and the telescopic end of the electric telescopic rod pushes the bearing plate to move upward. The bearing plate drives the transmission roller to move upward to complete the height adjustment of the film material during transportation. At the same time, when the bearing plate rises, the telescopic end of the telescopic limit plate is pulled up synchronously; when the bearing plate moves upward, it pulls the inclined plate to move synchronously. The bottom of the inclined plate is restricted by the rubber plate, which causes the hinge axis between itself and the bearing plate to start The inclined plate pushes the rubber plate to slide synchronously along the top of the base, and the rubber plate drives the arc-shaped soft plate to move synchronously. The arc surfaces of the arc-shaped soft plates on both sides contact and resist each other. At this time, the arc-shaped soft plate shrinks toward the inside of the rubber plate through the resistance force and pulls the built-in spring to deform synchronously. Afterwards, due to the increase in the center of gravity of the bearing plate, the vibration of the equipment during operation is amplified or when it is disturbed by external force, the rubber plate shakes slightly and drives the vertical plate to move synchronously. The vertical plate contacts the inner wall of the L-shaped plate to generate friction, which causes the hinge axis of the vertical plate to start rotating. At this time, the vertical plate swings along the inner wall of the L-shaped plate to disperse the force through friction.

[0007] According to the above technical solution, the inclined plate is located on the left side of the telescopic limit plate, a torsion spring is arranged between the inclined plate and the bearing plate, the bottom of the rubber plate is slidably installed on the top of the base, and the vertical plate contacts the inner wall of the L-shaped plate close to the electric telescopic rod.

[0008] According to the above technical solution, the anti-pollution device includes a transmission belt, a reciprocating screw, a negative pressure fan assembly and an arc-shaped baffle. The inner wall of the left part of the transmission belt is transmission-mounted on the outer wall of the front end of the transmission rod. Both ends of the reciprocating screw are rotatably mounted inside the bearing plate. The outer wall of the front end of the reciprocating screw is transmission-connected to the inner wall of the right part of the transmission belt. The negative pressure fan assembly penetrates inside and is movably mounted on the outer wall of the reciprocating screw. The front and back sides of the arc-shaped baffle are fixedly mounted inside the bearing plate. When the transmission rod rotates, it is driven by the transmission belt The reciprocating screw rotates, and when the reciprocating screw rotates along the inner wall of the supporting plate, the negative pressure fan assembly continuously contacts the reciprocating spiral groove of the reciprocating screw through the built-in block inside itself, so that the rotation of the reciprocating screw can drive the negative pressure fan assembly to slide forward along its own outer wall and reset, and when the bottom of the negative pressure fan assembly slides along the bottom of the inner wall of the supporting plate, the negative pressure fan assembly is started, and the negative pressure fan assembly sucks the dirt or dust attached to the bottom of the membrane material, and at the same time, the arc-shaped baffle blocks the un-extracted air around the negative pressure fan assembly through its own concave surface.

[0009] According to the above technical solution, the reciprocating screw is located on the right side of the transmission roller, the bottom of the negative pressure fan assembly is slidably installed on the bottom of the inner wall of the bearing plate, and the left side of the arc baffle contacts the right side of the negative pressure fan assembly.

[0010] According to the above technical solution, the anti-pollution device also includes a horizontal plate, a rotating wheel and a spiral dust reduction mesh plate. The bottom of the horizontal plate is fixedly installed on the bottom of the inner wall of the supporting plate, and the horizontal plate is located between the right side of the transmission roller and the left side of the negative pressure fan assembly. The bottom of the rotating wheel is rotatably installed on the top of the horizontal plate. The outer wall of the rotating wheel contacts the left side of the negative pressure fan assembly. The bottom of the spiral dust reduction mesh plate is fixedly installed on the top of the rotating wheel. At the same time, the horizontal plate limits the rotating wheel. When the negative pressure fan assembly slides back and forth, it contacts and rubs against the outer wall of the rotating wheel and prompts the rotating wheel to generate a rotational force. When the rotating wheel rotates, it drives the spiral dust reduction mesh plate to rotate.

[0011] The U-shaped plate is a plate that is fixedly mounted on the left side of the inner wall of the U-shaped plate, and the bottom of the hollow plate is slidably mounted on the bottom of the inner wall of the bearing plate. A U-shaped groove is provided on the top of the hollow plate, and both ends of the friction rubber wheel are rotatably mounted on the inside of the U-shaped groove of the hollow plate. When the negative pressure fan assembly slides forward, it no longer resists the front face of the right end of the U-shaped plate. At this time, the U-shaped plate slides forward through the elastic force of the spring reset between itself and the inside of the bearing plate, and the U-shaped plate drives the hollow plate to slide synchronously along the bottom of the inner wall of the bearing plate, and the hollow plate drives the friction rubber wheel to move synchronously. The top of the outer wall of the friction rubber wheel contacts and rubs with the bottom of the membrane material. When the friction force generated between the two is large, the friction rubber wheel is prompted to generate a rotational force.

[0012] The U-shaped push plate is a vertical cam which is provided to move the cam forward and backward, and the U-shaped push plate is a vertical cam which moves ... When the U-shaped push plate is driven by the stabilizing bar to move horizontally, the bottom arc surface of the U-shaped push plate contacts the resistance block at the top of the U-shaped frame to generate resistance force. At this time, the arc surface of the U-shaped push plate itself generates an upward movement force with the help of the pushing guide of the arc surface of the resistance block. The U-shaped push plate pushes the stabilizing bar to slide upward along the inner wall of the hollow slide plate, and the U-shaped push plate drives the resistance rubber plate to move synchronously. When the resistance rubber plate moves upward, it will resist the bottom of the membrane material. The resistance rubber plate generates a large resistance force when pushing the membrane material through its own arc surface and the design of the spring, and then the resistance rubber plate contracts toward the inside of the U-shaped push plate.

[0013] According to the above technical solution, a longitudinal spring is arranged between the stabilizing rod and the inside of the hollow slide, the outer wall of the U-shaped frame is located inside the hollow slide, and the arc surface of the outer wall of the resistance block is located on the bottom movement track of the U-shaped push plate.

[0014] The present invention provides a transmission structure of a gravure printing machine. It has the following beneficial effects: (1) The present invention adopts the arrangement of an anti-wave device, and cooperates with an electric telescopic rod, a load-bearing plate, a transmission rod, a transmission roller, a pressure roller, a telescopic limit plate, an inclined plate, a rubber plate, an arc-shaped soft plate, an L-shaped plate and a vertical plate, so as to facilitate timely adjustment of the conveying direction of the film material according to actual conditions, and can timely adjust the conveying height according to different conveying requirements, thereby improving the overall practicality of the device, simplifying the complicated work process of the staff and shortening the preparation time for film material conveying; at the same time, the arc-shaped soft plate is used for resistance and buffering to reduce the overall shaking force of the device under external force interference, and the vertical plate is used to disperse and eliminate the force borne by the rubber plate, thereby reducing the possibility of deformation of the rubber plate, ensuring that the rubber plate is always in a stationary state, preventing the transmission roller from reducing the conveying stability of the film material, and preventing the film material from deviating from the center of the transmission roller and reducing the printing quality.

[0015] (2) The present invention, through the setting of the anti-pollution device, cooperates with the transmission rod, transmission belt, reciprocating screw, negative pressure fan assembly, arc baffle, horizontal plate, rotating wheel and spiral dust reduction screen plate to expand the pumping range of the negative pressure fan assembly on the bottom of the membrane material, ensure the cleanliness of the outer wall of the membrane material to avoid the adhesion of dirt, prevent the dirt attached to the outer wall of the membrane material from interfering with the later ink coating process, avoid uneven ink coating due to the obstruction of dirt and thus reduce the printing clarity. At the same time, the arc baffle effectively prevents the outside air from approaching the working range of the negative pressure fan assembly to avoid interference with the working process of the negative pressure fan assembly; at the same time, the spiral dust reduction screen plate is used to rotate and attach the dirt that is pumped by the negative pressure fan assembly and has no time to absorb, thereby realizing the centralized collection of dirt, avoiding the dirt from being disturbed again and re-attached to the outer wall of the membrane material, thereby reducing the efficiency of dirt removal, and preventing the dirt from floating around, thereby increasing the difficulty of cleaning and maintenance of the entire device.

The friction rubber wheel slides horizontally and rotates to continuously stroke the bottom of the film material, thereby ensuring that the film material is conveyed in a flat posture, preventing the film material from being conveyed directly due to wrinkles generated during winding that have not been smoothed out, and preventing the creases from deepening under the limit of the pressure roller, thereby further interfering with the subsequent inking process; and enabling the contact rubber plate to reciprocately push the film material during horizontal movement, thereby expanding the pushing range of the contact rubber plate on the film material, thereby preventing the film material from becoming loose from the transmission mechanism inside the device as a whole during long-term conveying, ensuring that the film material is always in close contact with the transmission mechanism, and preventing the film material from being squeezed due to looseness during conveying, thereby preventing the conveying process from being interrupted.

The rubber plate 48 is hinged with a vertical plate 411 on one side of the L-shaped plate 410 through a torsion spring. The above cooperation is convenient for timely adjusting the conveying direction of the film material according to actual conditions, and at the same time, the conveying height can be timely adjusted according to different conveying requirements, thereby improving the overall practicality of the device, simplifying the complicated work process of the staff and shortening the preparation time for film material conveying; through the above cooperation, the arc-shaped soft plate 49 is used to resist and buffer to reduce the overall shaking force of the device under external force interference, and the vertical plate 411 is used to disperse and eliminate the force borne by the rubber plate 48, thereby reducing the possibility of deformation of the rubber plate 48, ensuring that the rubber plate 48 is always in a stationary state, preventing the transmission roller 44 from reducing the conveying stability of the film material, and avoiding the film material from deviating from the center of the transmission roller 44 and reducing the printing quality.

[0021] The inclined plate 47 is located on the left side of the telescopic limit plate 46, a torsion spring is arranged between the inclined plate 47 and the bearing plate 42, the bottom of the rubber plate 48 is slidably installed on the top of the base 1, and the vertical plate 411 is close to the electric telescopic rod 41 and contacts the inner wall of the L-shaped plate 410.

[0022] When in use, the base 1 is conveniently moved to the desired conveying position through the moving component 2, and the motor is started. When the electric output end rotates, it drives the transmission rod 43 to rotate. When the transmission rod 43 rotates along the inner wall of the carrying plate 42, it drives the transmission roller 44 to rotate, and the film material is inserted between the transmission roller 44 and the pressure roller 45. Under the rotation and conveyance of the transmission roller 44, the film material is conveyed to the right and rubs the bottom of the outer wall of the pressure roller 45. The pressure roller 45 starts to rotate in the same direction as the transmission roller 44 through friction. After that, the top of the film material is stretched to the bottom of the center roller 22 and then stretched upward until the bottom of the film material contacts the top of the conveying roller 31 to form a conveying process. When it is necessary to adjust the transmission roller 44 When the transmission height is increased, the electric telescopic rod 41 is started, and the telescopic end of the electric telescopic rod 41 pushes the carrying plate 42 to move upward, and the carrying plate 42 drives the transmission roller 44 to move upward, thereby completing the height adjustment when the film material is transported. At the same time, when the carrying plate 42 rises, the telescopic end of the telescopic limit plate 46 is pulled to rise synchronously. Through the above cooperation, it is convenient to adjust the conveying direction of the film material in time according to the actual situation, and at the same time, the conveying height can be adjusted in time according to different conveying requirements, thereby improving the overall practicality of the device, simplifying the complicated work process of the staff, and shortening the preparation time for film material transportation; when the carrying plate 42 moves upward, it pulls the inclined plate 47 to move synchronously, and the inclined plate 47 moves synchronously. The bottom of plate 47 is restricted by rubber plate 48, which causes the hinge axis between itself and the supporting plate 42 to start rotating. At this time, inclined plate 47 swings toward the axis of supporting plate 42 with the hinge axis as the axis center. Inclined plate 47 pushes rubber plate 48 to slide synchronously along the top of base 1. Rubber plate 48 drives arc-shaped soft plate 49 to move synchronously. The arc surfaces of arc-shaped soft plates 49 on both sides contact and resist each other. At this time, arc-shaped soft plate 49 contracts toward the inside of rubber plate 48 through the resistance force and pulls the built-in spring to deform synchronously. Afterwards, due to the increase of the center of gravity of supporting plate 42, when the vibration of the device during operation is amplified or when it is disturbed by external force, the rubber plate 48 produces a slight shake and drives the vertical The plate 411 moves synchronously, and the vertical plate 411 contacts the inner wall of the L-shaped plate 410 to generate friction, which causes the hinge axis of the vertical plate 411 to start rotating. At this time, the vertical plate 411 swings along the inner wall of the L-shaped plate 410 to disperse the friction force. Through the above cooperation, the arc-shaped soft plate 49 is used to resist and buffer the overall shaking of the device under external force interference, and the vertical plate 411 is used to disperse and eliminate the force borne by the rubber plate 48, thereby reducing the possibility of deformation of the rubber plate 48, ensuring that the rubber plate 48 is always in a stationary state, preventing the transmission roller 44 from reducing the stability of the film material conveying, and preventing the film material from deviating from the center of the transmission roller 44 and reducing the printing quality.

[0023] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-pollution device 5; The anti-pollution device 5 includes a transmission belt 51, a reciprocating screw 52, ​​a negative pressure fan assembly 53 and an arc-shaped baffle 54. The inner wall of the left part of the transmission belt 51 is transmission-mounted on the outer wall of the front end of the transmission rod 43. Both ends of the reciprocating screw 52 are rotatably mounted inside the bearing plate 42. The outer wall of the front end of the reciprocating screw 52 is transmission-connected to the inner wall of the right part of the transmission belt 51. The negative pressure fan assembly 53 penetrates inside and is movably mounted on the outer wall of the reciprocating screw 52. The front and back sides of the arc-shaped baffle 54 are fixedly mounted inside the bearing plate 42. Through the above cooperation, the twitching range of the negative pressure fan assembly 53 on the bottom of the membrane material is expanded, the cleanliness of the outer wall of the membrane material is ensured to avoid the adhesion of dirt, and the dirt attached to the outer wall of the membrane material is prevented from interfering with the later ink coating process, and the uneven ink coating caused by the obstruction of dirt is avoided, thereby reducing the printing clarity. At the same time, the arc-shaped baffle 54 effectively prevents the external air from approaching the working range of the negative pressure fan assembly 53, and avoids interfering with the working process of the negative pressure fan assembly 53.

The outer wall of the rotating wheel 56 contacts the left side of the negative pressure fan assembly 53. The bottom of the spiral dust reduction mesh plate 57 is fixedly installed on the top of the rotating wheel 56. Through the above cooperation, the spiral dust reduction mesh plate 57 is used to rotate and attach the dirt that is pulled by the negative pressure fan assembly 53 and has no time to absorb, thereby realizing the centralized collection of dirt, avoiding the dirt from being disturbed again and re-attaching to the outer wall of the membrane material, thereby reducing the efficiency of removing dirt, and preventing the dirt from floating around, thereby increasing the difficulty of cleaning and maintenance of the device as a whole.

[0026] When in use, the transmission rod 43 rotates and drives the reciprocating screw rod 52 to rotate through the transmission belt 51. When the reciprocating screw rod 52 rotates along the inner wall of the supporting plate 42, the negative pressure fan assembly 53 continuously contacts the reciprocating spiral groove of the reciprocating screw rod 52 through the built-in block inside itself, so that the rotation of the reciprocating screw rod 52 can drive the negative pressure fan assembly 53 to slide forward along its own outer wall and reset. When the bottom of the negative pressure fan assembly 53 slides along the bottom of the inner wall of the supporting plate 42, the negative pressure fan assembly 53 is started, and the negative pressure fan assembly 53 sucks the dirt or dust attached to the bottom of the membrane material. At the same time, the arc baffle 54 blocks the un-extracted air around the negative pressure fan assembly 53 through its own concave surface. The above cooperation expands the suction range of the negative pressure fan assembly 53 on the bottom of the membrane material, ensures the cleanliness of the outer wall of the membrane material to avoid the adhesion of dirt, and prevents the dirt attached to the outer wall of the membrane material from drying. The vacuum cleaner 54 can effectively prevent the outside air from approaching the working range of the negative pressure fan assembly 53, so as to avoid interfering with the working process of the negative pressure fan assembly 53; at the same time, the horizontal plate 55 limits the rotating wheel 56, and when the negative pressure fan assembly 53 slides back and forth, it contacts and rubs with the outer wall of the rotating wheel 56 and causes the rotating wheel 56 to generate a rotating force. When the rotating wheel 56 rotates, it drives the spiral dust reduction mesh plate 57 to rotate. Through the above cooperation, the spiral dust reduction mesh plate 57 is used to rotate and attach the dirt that is pulled by the negative pressure fan assembly 53 and has no time to absorb, thereby realizing the centralized collection of the dirt, avoiding the dirt from being disturbed for the second time and re-attaching to the outer wall of the membrane material, thereby reducing the cleaning efficiency of the dirt, and preventing the dirt from floating around, thereby increasing the difficulty of cleaning and maintenance of the entire device.

The front right side of the U-shaped plate 61 contacts the back of the negative pressure fan assembly 53. The left side of the hollow slide plate 62 is fixedly installed on the left side of the inner wall of the U-shaped plate 61.

[0030] When the negative pressure fan assembly 53 slides forward, it no longer contacts the front right end of the U-shaped plate 61. At this time, the U-shaped plate 61 slides forward through the elastic force of the spring reset between itself and the inside of the carrying plate 42, and the U-shaped plate 61 drives the hollow slide plate 62 to slide synchronously along the bottom of the inner wall of the carrying plate 42, and the hollow slide plate 62 drives the friction rubber wheel 63 to move synchronously. The top of the outer wall of the friction rubber wheel 63 contacts and rubs with the bottom of the film material. When the friction force generated between the two is large, the friction rubber wheel 63 is prompted to generate a rotational force. Through the above cooperation, the horizontal sliding and self-rotation force of the friction rubber wheel 63 continuously strokes the bottom of the film material to ensure that the film material is transported in a flat posture, preventing the film material from being directly transported due to the wrinkles generated during winding without being smoothed, and avoiding the deepening of the creases under the limit of the pressure roller 45, thereby further interfering with the subsequent ink coating process; when the hollow slide plate 62 slides, it drives the stabilizing rod 64 to move synchronously. In the process of the stabilizing rod 64 driving the U-shaped push plate 65 to move horizontally, the U-shaped The bottom arc surface of the push plate 65 contacts the resistance block 68 at the top of the U-shaped frame 67 to generate a resistance force. At this time, the arc surface of the U-shaped push plate 65 itself generates an upward movement force with the help of the pushing guide of the arc surface of the resistance block 68, and the U-shaped push plate 65 pushes the stabilizing rod 64 to slide upward along the inner wall of the hollow slide plate 62, and the U-shaped push plate 65 drives the resistance rubber plate 66 to move synchronously. When the resistance rubber plate 66 moves upward, it will resist the bottom of the membrane material. The resistance rubber plate 66 generates a large resistance force when pushing the membrane material through its own arc surface and the design of the spring, and then the resistance rubber plate 66 contracts toward the inside of the U-shaped push plate 65. Through the above cooperation, the resistance rubber plate 66 can push the membrane material back and forth during the horizontal movement, expand the pushing range of the resistance rubber plate 66 on the membrane material, avoid the membrane material from loosening with the transmission mechanism inside the device as a whole during long-term transportation, ensure that the membrane material and the transmission mechanism are always closely fitted, and prevent the membrane material from being squeezed due to looseness during transportation, resulting in interruption of the transportation process.
