A paper collecting mechanism is provided in the fixed frame. A drying mechanism is provided on the fixed frame. A controller is provided on the printing machine body. The beneficial effects of the present invention are simple structure and strong practicality. However, when the present invention is used for packaging box cardboard, when the cardboard is conveyed to the printing machine, the conveying device will vibrate when conveying the cardboard, causing the cardboard to be blocked and requiring manual correction during printing, resulting in the problem of increased manpower.

[0004] In view of this, the present invention proposes a violet light curing flexographic printing machine to solve the above problems. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art and solve the problem that the cardboard conveying device used in the prior art vibrates when conveying the cardboard, so that manual alignment is required during printing, resulting in increased manpower; the present invention proposes a purple light curing flexographic printing machine.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a purple light curing flexographic printing machine, including a paper feeding part, a printing part and a paper receiving part, the paper feeding part includes a bracket and a motor, the motor is fixedly connected to the outside of the bracket, a cardboard table is arranged at one end of the bracket, a conveying device is arranged in the bracket, the conveying device includes a conveyor belt, a baffle, a No. 1 wheel, a No. 2 wheel, a No. 1 shaft pulley, a No. 2 shaft pulley, a No. 1 gear and a No. 2 gear, the conveyor belt is located on the side of the cardboard table located in the bracket, and the end of the conveyor belt away from the cardboard table is fixedly connected to the output shaft of the motor, the outer surface of the conveyor belt is slidably connected to a No. 1 rubber block and a No. 2 rubber block, the No. 1 rubber block and The distance between the No. 2 rubber blocks can be adjusted, the baffle is arranged above the conveyor belt, and the baffle is slidably connected to the inner wall of the bracket, the No. 1 wheel is arranged on the side of the conveyor belt away from the cardboard platform, and the No. 1 wheel is rotatably connected to the bracket through a rotating shaft, the No. 2 wheel is rotatably connected above the No. 1 wheel through a rotating shaft, the No. 1 shaft pulley is fixedly connected to one end of the conveyor belt away from the cardboard platform, the No. 2 shaft pulley is fixedly connected to one end of the No. 1 wheel, and the No. 1 shaft pulley and the No. 2 shaft pulley are connected by a belt, the No. 1 gear is fixedly connected to one end of the No. 2 shaft pulley away from the No. 1 wheel, the No. 2 gear is fixedly connected to one end of the No. 2 wheel, and the No. 1 gear and the No. 2 gear are meshed with each other.

[0007] When in use, when the motor rotates counterclockwise, the motor drives the conveyor belt to rotate, and the No. 1 rubber block and the No. 2 rubber block set above the conveyor belt rotate with the conveyor belt. The distance between the No. 1 rubber block and the No. 2 rubber block is consistent with the length of the cardboard, and the No. 1 rubber block and the No. 2 rubber block are slidably connected to the conveyor belt, which can be adjusted at any time according to the size of the cardboard used. When the motor drives the conveyor belt to rotate, the No. 1 rubber block first contacts the end of the cardboard close to the conveyor belt. When the No. 1 rubber block contacts the cardboard, friction is generated between the cardboard and the No. 1 rubber block, and the No. 1 rubber block drives the cardboard to move onto the conveyor belt. When the cardboard leaves the cardboard platform, it passes through the baffle plate, and the height of the baffle plate only allows one piece of cardboard to pass through. Thus, it is impossible for several sheets of cardboard to enter the device at one time, thereby maintaining the efficiency of the paper feeding unit. Then, the No. 2 rubber block contacts the cardboard, and the No. 2 rubber block cooperates with the No. 1 rubber block to transmit the cardboard. When the motor rotates counterclockwise, the No. 1 shaft pulley rotates, and the No. 1 shaft pulley drives the No. 2 shaft pulley to rotate through the belt sleeved on the No. 1 shaft pulley, so that the No. 1 wheel rotates counterclockwise. When the No. 1 wheel rotates counterclockwise, the No. 1 gear arranged on the surface of the No. 2 shaft pulley rotates counterclockwise, the No. 1 gear meshes with the No. 2 gear, and the No. 2 gear rotates clockwise. The No. 2 wheel rotates clockwise. When the cardboard is transmitted to the No. 1 wheel, the No. 1 wheel and the No. 2 wheel rotate relatively. The cardboard is transmitted out of the paper feeding unit by the No. 1 wheel and the No. 2 wheel, thereby improving the paper feeding efficiency of the paper feeding unit to a certain extent.

[0008] Preferably, a No. 1 groove is provided on the upper surface of the cardboard table, a group of rollers are rotatably connected in the No. 1 groove through a rotating shaft, and an electric motor is provided at one end of the rollers close to the baffle plate, so that the rollers can rotate when working, a No. 2 groove is provided at one end of the baffle plate close to the conveyor belt, a slider is slidably connected in the No. 2 groove, and the slider has a blocking effect on the cardboard, and a stopper is provided at one end of the upper surface of the No. 1 rubber block away from the No. 2 rubber block, and when the No. 1 rubber block contacts the cardboard, the stopper squeezes the slider to move upward, so that the cardboard contacts the stopper, thereby increasing the conveying effect of the No. 1 rubber block on the cardboard;

[0009] When in use, when the motor rotates counterclockwise, the conveyor belt rotates, and the No. 1 rubber block contacts the cardboard along with the conveyor belt. Friction is generated between the No. 1 rubber block and the cardboard, so that the No. 1 rubber block drives the cardboard to enter above the conveyor belt. By opening a No. 1 groove on the cardboard platform, a connecting roller is rotated in the No. 1 groove through a rotating shaft, and the outer ring of the roller contacts the cardboard. When the No. 1 rubber block contacts the cardboard, the No. 1 rubber block drives the cardboard to move in the direction of the conveyor belt. When the cardboard moves, the cardboard contacts the roller, and the friction between the cardboard and the cardboard platform is reduced, and the roller rotates, so that the cardboard is more smoothly conveyed to the top of the conveyor belt, thereby improving the paper feeding efficiency of the paper feeding part to a certain extent and avoiding the cardboard from being stuck in the paper feeding part. The paper feeding unit is jammed, thereby improving the printing efficiency of the printing press; when the No. 1 rubber block contacts the paperboard, the block squeezes the slider, and the slider moves upward due to the squeezing, and the slider no longer blocks the paperboard, so that the paperboard contacts the block, and the electric motor rotates to drive the roller to move. When the roller rotates, the roller pushes the paperboard to move in the direction of the conveyor belt, and the paperboard hits the block, and the block blocks the paperboard. Through the push of the roller, the paperboard moves in the direction of the conveyor belt along with the No. 1 rubber block. When the No. 2 rubber block contacts the paperboard, the paperboard is transferred out of the paperboard platform, and the slider is free to fall in the No. 2 slot due to gravity. The slider blocks the paperboard again, so that the paperboard cannot be transferred out of the paperboard platform.

[0010] Preferably, a groove is provided at one end of the No. 1 rubber block away from the conveyor belt, and when the motor rotates counterclockwise, the conveyor belt brings the No. 1 rubber block into contact with the paperboard, so that the No. 1 rubber block carries the paperboard out;

[0011] During use, when the motor rotates counterclockwise, the No. 1 rubber block contacts the cardboard first. After the No. 1 rubber block contacts the cardboard, due to the friction force generated between the No. 1 rubber block and the cardboard, the cardboard is brought out of the cardboard platform by the No. 1 rubber block, and then the No. 2 rubber block contacts the cardboard. The No. 1 rubber block cooperates with the No. 2 rubber block to transfer the cardboard. By providing a groove above the No. 1 rubber block, when the No. 1 rubber block contacts the cardboard, the groove contacts the cardboard, and the contact edge of the groove and the cardboard improves the contact elasticity between the No. 1 rubber block and the cardboard. Under the action of the tangential force between the groove and the cardboard, the tangential force between the groove and the cardboard increases, and the tangential deformation increases accordingly, and the "friction effect" of the contact surface is also enhanced accordingly, thereby suppressing the slipping or slipping tendency between the No. 1 rubber block and the cardboard, so that when the No. 1 rubber block contacts the cardboard, the No. 1 rubber block can drive the cardboard to move more smoothly, thereby avoiding jamming in the paper feeding unit to a certain extent, thereby improving the use efficiency of the paper feeding unit.

[0012] Preferably, a protrusion is fixedly connected to one end face of the second baffle away from the conveyor belt, and the protrusion is located on the end surface of the second rubber block away from the first rubber block, and the shape of the protrusion is a right-angled trapezoidal block, and the small end is connected to the second rubber block;

[0013] When in use, after the No. 1 rubber block contacts the paperboard, the No. 1 rubber block drives the paperboard to be transmitted onto the conveyor belt, and then the No. 2 rubber block contacts the paperboard, and the No. 2 rubber block pushes the paperboard to be transmitted on the conveyor belt. By arranging a convex block on the surface of the No. 2 rubber block, when the No. 2 rubber block contacts the paperboard, the convex block arranged on the surface of the No. 2 rubber block pushes the paperboard, so that when the paperboard moves on the conveyor belt, the convex block arranged above the No. 2 rubber block limits the paperboard, so that the paperboard cannot move backward, thereby improving the paper feeding efficiency of the paper feeding unit, and by making the convex block in a right-angled trapezoidal shape with a small end connected to the surface of the No. 2 rubber block, when the convex block contacts the paperboard, the lower part of the convex block contacts the paperboard, and the upper part of the convex block squeezes the paperboard, so that the convex block cannot vibrate to a certain extent, thereby improving the use efficiency of the convex block to a certain extent, thereby improving the paper feeding efficiency of the paper feeding unit.

[0014] Preferably, one end of the baffle plate close to the paperboard platform is horizontally slidably connected to a No. 1 block, and the No. 1 block is used to limit the position of the paperboard. The upper end surface of the No. 2 rubber block is horizontally slidably connected to a No. 2 block, and the No. 2 block is used to limit the position of the paperboard.

[0015] When in use, when the No. 1 rubber block and the No. 2 rubber block transmit the cardboard, the No. 1 block is connected by horizontal sliding at one end of the baffle, and the No. 1 block can be adjusted according to the size of the cardboard. When the cardboard is placed on the cardboard table, the No. 1 block limits the cardboard to prevent the cardboard from tilting. When the No. 1 rubber block transmits the cardboard, when the No. 1 rubber block contacts the cardboard, the cardboard is limited by the No. 1 block and will not tilt, thereby increasing the printing efficiency of the printing press. The No. 2 block is connected by horizontal sliding above the No. 2 rubber block, and the gap between the No. 2 block and the No. 1 block is the same, which can be adjusted according to the size of the cardboard. When the No. 2 rubber block contacts the cardboard, the cardboard is limited by the No. 1 block, so that when the cardboard falls on the No. 2 block, the position of the cardboard is stuck between the No. 2 blocks, so that the No. 2 block limits the cardboard, so that when the cardboard is transmitted on the conveyor belt, the cardboard remains stable and will not swing, thereby increasing the printing efficiency when the cardboard is transmitted to the printing part.

[0016] Preferably, the second wheel is made of rubber, and wire grooves are evenly formed on the surface of the second wheel;

[0017] When in use, when the No. 1 rubber block and the No. 2 rubber block are transmitting the cardboard, the No. 1 block leaves the cardboard first, and the No. 2 rubber block pushes the cardboard to move in the direction of the No. 1 wheel and the No. 2 wheel, and the cardboard contacts the No. 1 wheel first. When the cardboard contacts the No. 1 wheel, the No. 1 wheel rotates clockwise. Under the push of the No. 2 rubber block and the clockwise rotation of the No. 1 wheel, the cardboard moves between the No. 1 wheel and the No. 2 wheel, and under the limiting effect of the No. 2 block above the No. 2 rubber block, when the No. 1 wheel and the No. 2 wheel transmit the cardboard, the cardboard will not vibrate in position. When the cardboard contacts the No. 2 wheel, by evenly opening wire grooves on the surface of the No. 2 wheel, when the No. 2 wheel rotates clockwise, the No. 1 wheel and the No. 2 wheel rotate relatively, so that the cardboard is transmitted to the printing part. Through the wire grooves, when the No. 2 wheel is transmitting, the horizontal friction between the cardboard and the No. 2 wheel is increased, so that the cardboard is prevented from horizontal vibration during transmission, so that when the cardboard is transmitted to the printing part, the cardboard does not need to be manually straightened, thereby improving the use efficiency of the printing press.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. In the ultraviolet light curing flexographic printing machine described in the present invention, when the No. 1 rubber block contacts the paperboard, the No. 1 rubber block drives the paperboard to be transmitted to the conveyor belt, and the No. 2 rubber block pushes the paperboard to be transmitted on the conveyor belt. The protrusion is in the shape of a right-angled trapezoid. When the protrusion contacts the paperboard, the lower part of the protrusion contacts the paperboard, and the upper part of the protrusion squeezes the paperboard, so that the protrusion cannot vibrate to a certain extent, thereby improving the use efficiency of the protrusion to a certain extent, thereby improving the paper feeding efficiency of the paper feeding part.

[0020] 2. In the ultraviolet light curing flexographic printing machine described in the present invention, when the motor rotates counterclockwise, the conveyor belt rotates, the No. 1 rubber block contacts the paperboard along with the conveyor belt, and the roller is connected to the No. 1 groove through the rotating shaft, and the outer ring of the roller contacts the paperboard. The No. 1 rubber block drives the paperboard to move toward the conveyor belt, and the paperboard contacts the roller, and the friction between the paperboard and the paper plate is reduced, and the roller rotates, so that the paperboard is more smoothly conveyed to the top of the conveyor belt, thereby improving the paper feeding efficiency of the paper feeding part to a certain extent.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 7As shown, a violet light curing flexographic printing machine includes a paper feeding part, a printing part and a paper receiving part. The paper feeding part includes a bracket 1 and a motor, and the motor is fixedly connected to the outside of the bracket. A cardboard table 11 is arranged at one end of the bracket 1. A conveying device 2 is arranged in the bracket 1. The conveying device 2 includes a conveyor belt 21, a baffle 22, a first wheel 23, a second wheel 24, a first shaft pulley 25, a second shaft pulley 26, a first gear 27 and a second gear 28. The conveyor belt 21 is located on the side of the cardboard table 11 located in the bracket 1, and the end of the conveyor belt 21 away from the cardboard table 11 is fixedly connected to the output shaft of the motor. A first rubber block 211 and a second rubber block 212 are slidably connected to the outer surface of the conveyor belt 21. The baffle 22 is provided with a first wheel 23, a second wheel 24, a first shaft pulley 25, a second shaft pulley 26, a first gear 27 and a second gear 28. The conveyor belt 21 is located on the side of the cardboard table 11 located in the bracket 1, and the end of the conveyor belt 21 away from the cardboard table 11 is fixedly connected to the output shaft of the motor. A first rubber block 211 and a second rubber block 212 are slidably connected to the outer surface of the conveyor belt 21. The first wheel 23 is arranged on the side of the conveyor belt 21 away from the cardboard platform 11, and the first wheel 23 is rotatably connected to the bracket 1 through a rotating shaft, and the second wheel 24 is rotatably connected to the top of the first wheel 23 through a rotating shaft, the first shaft pulley 25 is fixedly connected to one end of the conveyor belt 21 away from the cardboard platform 11, the second shaft pulley 26 is fixedly connected to one end of the first wheel 23, and the first shaft pulley 25 and the second shaft pulley 26 are connected through a belt, the first gear 27 is fixedly connected to one end of the second shaft pulley 26 away from the first wheel 23, the second gear 28 is fixedly connected to one end of the second wheel 24, and the first gear 27 and the second gear 28 are meshed with each other.

[0032] When in use, when the motor rotates counterclockwise, the motor drives the conveyor belt 21 to rotate, and the No. 1 rubber block 211 and the No. 2 rubber block 212 arranged above the conveyor belt 21 rotate with the conveyor belt 21, and the distance between the No. 1 rubber block 211 and the No. 2 rubber block 212 is consistent with the length of the cardboard 3, and the No. 1 rubber block 211 and the No. 2 rubber block 212 are slidably connected to the conveyor belt 21, and can be adjusted at any time according to the size of the cardboard 3 used. When the motor drives the conveyor belt 21 to rotate, the No. 1 rubber block 211 first contacts the end of the cardboard 3 close to the conveyor belt 21. When the No. 1 rubber block 211 contacts the cardboard 3, friction is generated between the cardboard 3 and the No. 1 rubber block 211, and the No. 1 rubber block 211 drives the cardboard 3 to move onto the conveyor belt 21. When the cardboard 3 leaves the cardboard platform 11, the baffle 22 is set, and the height of the baffle 22 only allows one piece of cardboard 3 to pass through, so that the device cannot enter at one time. Several sheets of paperboards 3 are formed, thereby maintaining the use efficiency of the paper feeding unit. Then, the second rubber block 212 contacts the paperboard 3, and the second rubber block 212 cooperates with the first rubber block 211 to transmit the paperboard 3. When the motor rotates counterclockwise, it rotates through the first shaft pulley 25. Through the belt sleeved on the first shaft pulley 25, the first shaft pulley 25 drives the second shaft pulley 26 to rotate, so that the first wheel 23 rotates counterclockwise. When the first wheel 23 rotates counterclockwise, the first gear 27 arranged on the surface of the second shaft pulley 26 rotates counterclockwise, the first gear 27 is meshed with the second gear 28, and the second gear 28 rotates clockwise, and the second wheel 24 rotates clockwise. When the paperboard 3 is transmitted to the first wheel 23, the first wheel 23 and the second wheel 24 rotate relatively, so that the paperboard 3 is transmitted out of the paper feeding unit by the first wheel 23 and the second wheel 24, thereby improving the paper feeding efficiency of the paper feeding unit to a certain extent.

[0033] As a specific embodiment of the present invention, a No. 1 groove 111 is provided on the upper end surface of the paperboard table 11, a group of rollers 112 are rotatably connected in the No. 1 groove 111 through a rotating shaft, and an electric motor is provided at one end of the rollers 112 close to the baffle 22, so that the rollers 112 can rotate when working, and a No. 2 groove 221 is provided at one end of the baffle 22 close to the conveyor belt 21, a slider 222 is slidably connected in the No. 2 groove 221, and the slider 222 has a blocking effect on the paperboard 3, and a stopper 215 is provided on the end of the upper surface of the No. 1 rubber block 211 away from the No. 2 rubber block 212, and when the No. 1 rubber block 211 contacts the paperboard 3, the stopper 215 squeezes the slider 222 to move upward, so that the paperboard 3 contacts the stopper 215, thereby increasing the conveying effect of the No. 1 rubber block 211 on the paperboard 3;

[0034] When in use, when the motor rotates counterclockwise, the conveyor belt 21 rotates, and the No. 1 rubber block 211 contacts the cardboard 3 along with the conveyor belt 21. The friction between the No. 1 rubber block 211 and the cardboard 3 causes the No. 1 rubber block 211 to drive the cardboard 3 to enter above the conveyor belt 21. By opening a No. 1 groove 111 on the cardboard platform 11, the roller 112 is connected to the No. 1 groove 111 by rotating the shaft, and the outer ring of the roller 112 contacts the cardboard 3. When the No. 1 rubber block 211 contacts the cardboard 3, the No. 1 rubber block 211 drives the cardboard 3 to move toward the conveyor belt 21. When the cardboard 3 moves, the cardboard 3 contacts the roller 112, and the friction between the cardboard 3 and the cardboard platform 11 is reduced, and the roller 112 rotates, so that the cardboard 3 is more smoothly conveyed to the top of the conveyor belt 21, thereby improving the paper feeding efficiency of the paper feeding part to a certain extent, and avoiding the cardboard 3 in the paper feeding part. The cardboard 3 is stuck, thereby improving the printing efficiency of the printing press; when the No. 1 rubber block 211 contacts the cardboard 3, the block 215 squeezes the slider 222, and the slider 222 moves upward under the squeezing, and the slider 222 no longer blocks the cardboard 3, so that the cardboard 3 contacts the block 215, and the electric motor rotates to drive the roller 112 to move. When the roller 112 rotates, the roller 112 pushes the cardboard 3 to move in the direction of the conveyor belt 21, and the cardboard 3 hits the block 215, and the block 215 blocks the cardboard 3. Through the push of the roller 112, the cardboard 3 moves in the direction of the conveyor belt 21 along with the No. 1 rubber block 211. When the No. 2 rubber block 212 contacts the cardboard 3, the cardboard 3 is transferred out of the cardboard platform 11, and the slider 222 is free to fall in the No. 2 slot 221 under the action of gravity. The slider 222 blocks the cardboard 3 again, so that the cardboard 3 cannot be transferred out of the cardboard platform 11.

[0035] As a specific embodiment of the present invention, a groove 213 is provided at one end of the first rubber block 211 away from the conveyor belt 21. When the motor rotates, the conveyor belt 21 brings the first rubber block 211 into contact with the paperboard 3, so that the first rubber block 211 brings the paperboard 3 out.

[0036] When in use, when the motor rotates counterclockwise, the No. 1 rubber block 211 first contacts the cardboard 3. After the No. 1 rubber block 211 contacts the cardboard 3, due to the friction between the No. 1 rubber block 211 and the cardboard 3, the cardboard 3 is brought out of the cardboard stand 11 by the No. 1 rubber block 211, and then the No. 2 rubber block 212 contacts the cardboard 3. The No. 1 rubber block 211 cooperates with the No. 2 rubber block 212 to make the cardboard 3 come out. By providing a groove 213 above the No. 1 rubber block 211, when the No. 1 rubber block 211 contacts the cardboard 3, the groove 213 contacts the cardboard 3, and the groove 213 contacts the cardboard 3. The edge of the groove 213 in contact with the paperboard 3 improves the contact elasticity between the first rubber block 211 and the paperboard 3. Under the action of the tangential force between the groove 213 and the paperboard 3, the tangential force between the groove 213 and the paperboard 3 increases, and the tangential deformation increases accordingly, and the "friction effect" of the contact surface is also enhanced accordingly, thereby suppressing the slipping or slipping tendency between the first rubber block 211 and the paperboard 3. When the first rubber block 211 contacts the paperboard 3, the first rubber block 211 can drive the paperboard 3 to move more smoothly, thereby avoiding jamming in the paper feeding unit to a certain extent, thereby improving the use efficiency of the paper feeding unit.

[0037] As a specific embodiment of the present invention, a protrusion 223 is fixedly connected to one end surface of the second baffle 22 away from the conveyor belt 21. The protrusion 223 is located on the end surface of the second rubber block 212 away from the first rubber block 211, and the shape of the protrusion 223 is a right-angled trapezoidal block, and the small end is connected to the second rubber block 212;

[0038] When in use, after the No. 1 rubber block 211 contacts the cardboard 3, the No. 1 rubber block 211 drives the cardboard 3 to be transmitted to the conveyor belt 21, and then the No. 2 rubber block 212 contacts the cardboard 3, and the No. 2 rubber block 212 has a pushing effect on the cardboard 3, so that the cardboard 3 is transmitted on the conveyor belt 21, and the protrusion 223 provided on the surface of the No. 2 rubber block 212 is provided. When the No. 2 rubber block 212 contacts the cardboard 3, the protrusion 223 provided on the surface of the No. 2 rubber block 212 has a pushing effect on the cardboard 3, so that the cardboard 3 moves on the conveyor belt 21. The protrusion 223 arranged above the rubber block 212 has a limiting effect on the paperboard 3, so that the paperboard 3 cannot move backward, thereby improving the paper feeding efficiency of the paper feeding unit. The protrusion 223 is in the shape of a right-angled trapezoid, and the small end is connected to the surface of the second rubber block 212. When the protrusion 223 contacts the paperboard 3, the lower part of the protrusion 223 contacts the paperboard 3, and the upper part of the protrusion 223 squeezes the paperboard 3, which prevents the protrusion 223 from vibrating to a certain extent, thereby improving the use efficiency of the protrusion 223 to a certain extent, thereby improving the paper feeding efficiency of the paper feeding unit.

[0039] As a specific embodiment of the present invention, the baffle 22 is horizontally slidably connected to a first block 224 at one end close to the paperboard stand 11, and the first block 224 is used to limit the position of the paperboard 3. The upper end surface of the second rubber block 212 is horizontally slidably connected to a second block 214, and the second block 214 is used to limit the position of the paperboard 3.

[0040] When in use, when the No. 1 rubber block 211 and the No. 2 rubber block 212 are transmitting the cardboard 3, the No. 1 block 224 is horizontally slidably connected to one end of the baffle 22, and the No. 1 block 224 can be adjusted according to the size of the cardboard 3. When the cardboard 3 is placed on the cardboard stand 11, the No. 1 block 224 limits the cardboard 3 to prevent the cardboard 3 from tilting. When the No. 1 rubber block 211 is transmitting the cardboard 3, when the No. 1 rubber block 211 contacts the cardboard 3, the cardboard 3 is limited by the No. 1 block 224 and does not tilt, thereby increasing the printing efficiency of the printing press. The second rubber block 212 is horizontally slidably connected to the second block 214, and the gap between the second block 214 and the first block 224 is the same, which can be adjusted according to the size of the cardboard 3. When the second rubber block 212 contacts the cardboard 3, the cardboard 3 is limited by the first block 224, so that when the cardboard 3 falls on the second block 214, the position of the cardboard 3 is stuck between the second blocks 214, so that the second block 214 limits the cardboard 3, so that when the cardboard 3 is transmitted on the conveyor belt 21, the cardboard 3 remains stable and does not swing, so that when the cardboard 3 is transmitted to the printing part, the printing efficiency is increased.

[0041] As a specific implementation of the present invention, the second wheel 24 is made of rubber, and wire grooves 241 are evenly formed on the surface of the second wheel 24;

[0042] When in use, when the No. 1 rubber block 211 and the No. 2 rubber block 212 are conveying the cardboard 3, the No. 1 block 224 leaves the cardboard 3 first, and the No. 2 rubber block 212 pushes the cardboard 3 to move in the direction of the No. 1 wheel 23 and the No. 2 wheel 24, and the cardboard 3 first contacts the No. 1 wheel 23. When the cardboard 3 contacts the No. 1 wheel 23, the No. 1 wheel 23 rotates counterclockwise. Under the push of the No. 2 rubber block 212 and the counterclockwise rotation of the No. 1 wheel 23, the cardboard 3 moves between the No. 1 wheel 23 and the No. 2 wheel 24, and under the limiting action of the No. 2 block 214 above the No. 2 rubber block 212, when the No. 1 wheel 23 and the No. 2 wheel 24 are in contact with each other, the cardboard 3 moves between the No. 1 wheel 23 and the No. 2 wheel 24. When the cardboard 3 is transmitted by the No. 2 wheel 24, the cardboard 3 will not vibrate in position. When the cardboard 3 contacts the No. 2 wheel 24, by evenly opening the line grooves 241 on the surface of the No. 2 wheel 24, when the No. 2 wheel 24 rotates clockwise, the No. 1 wheel 23 and the No. 2 wheel 24 rotate relatively, so that the cardboard 3 is transmitted to the printing part. Through the line grooves 241, when the No. 2 wheel 24 is transmitted, the horizontal friction between the cardboard 3 and the No. 2 wheel 24 is increased, so that the cardboard 3 is prevented from vibrating horizontally when being transmitted, so that when the cardboard 3 is transmitted to the printing part, the cardboard 3 does not need to be manually straightened, thereby improving the use efficiency of the printing press.

[0043] The specific workflow is as follows;

[0044] When the motor rotates counterclockwise, the motor drives the conveyor belt 21 to rotate, and the No. 1 rubber block 211 and the No. 2 rubber block 212 arranged above the conveyor belt 21 rotate with the conveyor belt 21. The distance between the No. 1 rubber block 211 and the No. 2 rubber block 212 is consistent with the length of the cardboard 3, and the distance between the No. 1 rubber block 211 and the No. 2 rubber block 212 can be adjusted at any time according to the size of the cardboard 3 used. When the motor drives the conveyor belt 21 to rotate, the No. 1 rubber block 211 first contacts the end of the cardboard 3 close to the conveyor belt 21. When the No. 1 rubber block 211 contacts the cardboard 3, friction is generated between the cardboard 3 and the No. 1 rubber block 211, and the No. 1 rubber block 211 drives the cardboard 3 toward the conveyor belt 21 moves, through the baffle plate 22, the height of the baffle plate 22 allows only one cardboard 3 to pass through, the first shaft pulley 25 drives the second shaft pulley 26 to rotate, so that the first wheel 23 rotates counterclockwise, the first gear 27 set on the surface of the second shaft pulley 26 rotates counterclockwise, the first gear 27 is meshed with the second gear 28, the second gear 28 rotates clockwise, and the second wheel 24 rotates clockwise. When the cardboard 3 is transmitted to the first wheel 23, the first wheel 23 and the second wheel rotate relatively, so that the cardboard 3 is transmitted out of the paper feeding part by the first wheel 23 and the second wheel 24, thereby improving the paper feeding efficiency of the paper feeding part to a certain extent; by opening a first slot on the cardboard table 11 111, the roller 112 is connected to the cardboard 3 by rotating the shaft in the No. 1 groove 111, the outer ring of the roller 112 contacts the cardboard 3, the No. 1 rubber block 211 drives the cardboard 3 to move toward the conveyor belt 21, and the roller 112 rotates; by providing a groove 213 above the No. 1 rubber block 211, the friction between the No. 1 rubber block 211 and the cardboard 3 is enhanced; when the No. 2 rubber block 212 contacts the cardboard 3, the protrusion 223 pushes the cardboard 3, and the protrusion 223 limits the cardboard 3, so that the cardboard 3 cannot retreat, so that the protrusion 223 is in a right-angled trapezoid shape, the lower part of the protrusion 223 contacts the cardboard 3, and the upper part of the protrusion 223 squeezes the cardboard 3; the No. 1 block 2 24 can be adjusted according to the size of the cardboard 3, the No. 1 block 224 limits the cardboard 3, and the gap between the No. 2 block 214 and the No. 1 block 224 is the same, which can be adjusted according to the size of the cardboard 3. When the No. 2 rubber block 212 contacts the cardboard 3, the No. 2 block 214 limits the cardboard 3, and the No. 1 wheel 23 and the No. 2 wheel 24 rotate relatively, so that the cardboard 3 is transmitted to the printing part. Through the line groove 241, when the No. 2 wheel 24 is transmitted, the horizontal friction between the cardboard 3 and the No. 2 wheel 24 is increased, so that the cardboard 3 is prevented from horizontal vibration when it is transmitted, so that when the cardboard 3 is transmitted to the printing part, the cardboard 3 does not need to be manually straightened, thereby improving the use efficiency of the printing press.
