DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example 1: Reference Figures 1-8 A pulling head for an intermittent printing press includes: a U-shaped frame 1, a paper feeding roller 2, a front pulling head 3, a rear pulling head 4, a scale member 5, a sensor and a controller. The paper feeding roller 2, the sensor, the front pulling head 3 and the rear pulling head 4 are installed on the inner wall of the U-shaped frame 1. The front pulling head 3 is arranged below the rear pulling head 4. The front pulling head 3, the rear pulling head 4 and the sensor are connected to the controller. A scale member 5 is installed at the end of the U-shaped frame 1, and the scale member 5 is arranged parallel to the rear pulling head 4.

[0029] The principles and beneficial effects of the above scheme are:

[0030] When the printing press needs to transport the paper to be printed, the operator passes the paper to be printed through the paper feed roller 2, the front pull head 3, the rear pull head 4 and the scale part 5 in sequence. The controller starts the sensor to measure the thickness of the paper to be printed. The sensor transmits the measured paper thickness to the controller. The controller controls the front pull head 3 and the rear pull head 4 to apply pressure to the paper. After starting the device, the front pull head 3 and the rear pull head 4 must keep the rotation direction and speed consistent during operation. The structure of the front pull head 3 and the rear pull head 4 each having two sets of pull heads can better press the paper to be printed and prevent the pull head from slipping during printing due to the small area of ​​the paper pressing roller 9, resulting in inaccurate positioning of the printed product and ghosting of the printed pattern. The double pull head structure can control and adjust the paper pressing pressure according to the different tensions that the printing paper can withstand.

[0031] The front pulling head 3 and the rear pulling head 4 have the same structure; the front pulling head 3 includes: a hollow pulling head roller 6, a paper pressing member 7 and a second paper pressing member 8, the two inner walls of the U-shaped frame 1 are respectively rotatably connected to one end of the hollow pulling head roller 6, one end of the hollow pulling head roller 6 passes through the side wall of the U-shaped frame 1 and is connected to the output end of the motor, the motor is connected to the controller, and the motor is installed on the side wall of the U-shaped frame 1. The inner wall of the U-shaped frame 1 is equipped with a paper pressing member 7 and a second paper pressing member 8, and the paper pressing member 7 and the second paper pressing member 8 are respectively arranged on both sides of the hollow pulling head roller 6.

[0032] The principles and beneficial effects of the above scheme are:

[0033] The two inner walls of the U-shaped frame 1 are respectively rotatably connected to one end of the hollow pulling head roller 6, and one end of the hollow pulling head roller 6 passes through the side wall of the U-shaped frame 1 and is connected to the output end of the motor. The motor provides power for the rotation of the hollow pulling head roller 6, and the paper pressing member 7 and the second paper pressing member 8 are placed on both sides of the hollow pulling head roller 6. When the top surface of the paper to be printed is in contact with the side wall of the hollow pulling head roller 6, the paper pressing member 7 and the second paper pressing member 8 press the bottom surface of the paper to be printed. When the paper to be printed needs to be conveyed, the controller starts the motor, and the motor drives the hollow pulling head roller 6 to rotate, and the paper pressing member 7 and the second paper pressing member 8 guide the paper to be printed, thereby improving the conveying efficiency of the paper to be printed; at the same time, it is convenient to prevent the paper to be printed from entering the device; the side wall of the hollow pulling head roller 6 is covered with a rubber layer, which is convenient for increasing the friction of the device on the paper to be printed, preventing the paper from slipping, and avoiding the quality of the paper to be printed from deteriorating during printing.

[0034] The paper pressing member 7 and the second paper pressing member 8 have the same structure; the paper pressing member 7 includes: a paper pressing roller 9, a mounting seat 10 and a driving member 11. The two inner walls of the U-shaped frame 1 are respectively hinged to one end of a mounting seat 10, and the side wall of the mounting seat 10 is connected to the inner wall of the U-shaped frame 1 through a reset spring. The other side wall of the mounting seat 10 is connected to the driving member 11. A paper pressing roller 9 is installed between the two mounting seats 10, and the paper pressing roller 9 is arranged on one side of the hollow pulling head roller 6.

[0035] The principles and beneficial effects of the above scheme are:

[0036] The side walls of the press roller 9 are covered with a rubber layer to increase the friction force of the press roller 9 on the bottom surface of the paper to be printed. When the press roller 9 and the hollow pulling head roller 6 cooperate with each other to transport the paper, the rubber layer on the press roller 9 rubs against the paper to be printed, and the press roller 9 rotates to prevent the bottom surface of the paper to be printed from sliding and rubbing against the press roller 9, which causes damage to the paper; the side walls of the press roller 9 and the side walls of the hollow pulling head roller 6 cooperate with each other to press the paper to be printed between the two, and the two ends of the press roller 9 are respectively mounted on a mounting seat 10. The end side walls of the mounting seat 10 are hinged to the inner wall of the U-shaped frame 1, and the other end of the mounting seat 10 is connected to the inner wall of the U-shaped frame 1 through a return spring. When it is necessary to adjust the distance between the press roller 9 and the hollow pulling head roller 6 to further adjust the pressure on the paper to be printed, the driving member 11 drives one end of the mounting seat 10 to rotate around its other end, and adjusts the pressure of the press roller 9 on the hollow pulling head roller 6 by releasing the elastic force of the return spring, thereby improving the efficiency of pressure adjustment.

[0037] The driving member 11 includes: a pressure wheel 12, a semi-cylinder 13 and a connecting rod 14. The side wall of the end of the mounting seat 10 is equipped with a pressure wheel 12. The side wall of the pressure wheel 12 is frictionally connected to the plane side wall of the semi-cylinder 13. The semi-cylinder 13 is rotatably matched with the U-shaped frame 1. The other end of the semi-cylinder 13 is connected to the end of the connecting rod 14. The other end of the connecting rod 14 is hinged to the cylinder output end of the side wall of the U-shaped frame 1, and the cylinder is connected to the controller.

[0038] The principles and beneficial effects of the above scheme are:

[0039] When the pressure of the printing paper is reduced, the output end of the cylinder shortens and drives the connecting rod 14 to rotate forward, and the connecting rod 14 rotates forward to drive the semi-cylinder 13 to rotate forward, and the semi-cylinder 13 releases the pressure wheel 12, and the return spring extends to make the paper pressing roller 9 close to the hollow pulling head roller 6, thereby increasing the pressure on the printing paper; when the pressure of the printing paper is reduced, the output end of the cylinder shortens and drives the connecting rod 14 to reverse, and the reverse rotation of the connecting rod 14 drives the semi-cylinder 13 to reverse, and the semi-cylinder 13 rotates to recycle the pressure wheel 12, and the return spring contracts to make the paper pressing roller 9 away from the hollow pulling head roller 6, thereby reducing the pressure on the printing paper. By setting the friction fit between the pressure wheel 12 and the semi-cylinder 13, it is convenient to accurately adjust the pressure value; the setting of the mechanism is simplified and the effect of continuous operation of the mechanism is improved.

[0040] The ruler component 5 includes: a ruler rod 15, a roller 16 and a paper stop 17. The end of the U-shaped frame 1 is connected to the side walls of the ruler rod 15 at both ends. The top surface of the ruler rod 15 is rotatably connected to multiple rollers 16. The rollers 16 are arranged parallel to the output end of the rear pulling head 4. Two paper stops 17 are slidably connected to the ruler rod 15.

[0041] The top surface of the ruler rod 15 is provided with scale lines.

[0042] The principles and beneficial effects of the above scheme are:

[0043] Before conveying the paper to be printed, the relative positions of the two paper stops 17 on the ruler rod 15 are adjusted according to the width of the paper to be printed to prevent the paper to be printed from shaking left and right during conveyance, which may lead to a decrease in printing quality; a plurality of rollers 16 are provided on the ruler rod 15, and the rollers 16 are frictionally engaged with the bottom surface of the paper to be printed, and the top side walls of the rollers 16 are located above the top surface of the ruler rod 15 to prevent the scale lines on the ruler rod 15 from being worn due to the friction of the paper to be printed during long-term operation of the device; at the same time, a plurality of unpowered rollers 16 are provided, and the side walls of the rollers 16 prevent the wear of the paper to be printed during conveyance while conveying the paper to be printed.

[0044] The paper stop 17 includes: a mounting frame 18, a transverse guide wheel 19, a longitudinal guide wheel 20 and a positioning member 21. The bottom surface of the ruler rod 15 is slidably connected to the bottom ends of the two mounting frames 18. Each side wall of the mounting frame 18 is equipped with a transverse guide wheel 19. The two transverse guide wheels 19 are arranged facing each other. The transverse guide wheel 19 is arranged above the top surface of the ruler rod 15. The top end of the mounting frame 18 is threadedly connected to the longitudinal guide wheel 20. The end wall of the mounting frame 18 is equipped with a positioning member 21. The end of the positioning member 21 is in contact with the end of the ruler rod 15.

[0045] The principles and beneficial effects of the above scheme are:

[0046] During the transportation of the paper to be printed, two oppositely arranged transverse guide wheels 19 guide the two side walls of the paper to be printed, and two longitudinal guide wheels 20 guide the top surface of the paper to be printed. The side walls of the transverse guide wheels 19 and the longitudinal guide wheels 20 are covered with rubber to prevent the paper to be printed from slipping during transportation, resulting in a decrease in printing quality; the longitudinal guide wheels 20 and the roller 16 cooperate to guide the paper to be printed to ensure stability during transportation; the two oppositely arranged transverse guide wheels 19 further prevent the paper to be printed from shaking left and right, and prevent the paper from producing ghosting when printing.

[0047] The positioning member 21 includes a handwheel 22 and a screw rod 23 . The screw hole at the end of the mounting frame 18 is threadedly connected to the screw rod 23 . The handwheel 22 is installed at one end of the screw rod 23 , and the other end of the screw rod 23 contacts and cooperates with the side wall of the ruler rod 15 .

[0048] The principles and beneficial effects of the above scheme are:

[0049] According to the width of the paper to be printed, the mounting bracket 18 is moved. When the mounting bracket 18 reaches the position relative to the scale line on the ruler rod 15, the hand wheel 22 is rotated forward. The forward rotation of the hand wheel 22 drives the screw rod 23 to rotate forward. Under the guidance of the screw hole, the end of the screw rod 23 is tightly attached to the side wall of the ruler rod 15 to position the mounting bracket 18, which simplifies the structural design and reduces the production cost of the device.

[0050] It also includes: an auxiliary part 31; the auxiliary part 31 includes: a guide seat 24, an exhaust hole 25, a buffer plate 26 and a conversion part 27. A guide seat 24 is provided on both sides of the hollow slider roller 6, and the two ends of the guide seat 24 are respectively connected to the two inner walls of the U-shaped frame 1. An air guide hole is opened in the guide seat 24, and the air guide hole is connected to one side of the conversion part 27 through the conduit on the U-shaped frame 1. The conversion part 27 is installed at the end of the ruler 15. The side wall of the air guide hole is connected to one end of a plurality of exhaust holes 25, and the other end of the exhaust holes 25 are parallel to the tangent of the side wall of the hollow slider roller 6. The top surface of the guide seat 24 is parallel to the bottom surface of the buffer plate 26. The top surface of the buffer plate 26 is connected to the mounting plate on the inner wall of the U-shaped frame 1 through a plurality of buffer springs. The other side of the conversion part 27 is rotatably connected to one end of the hollow slider roller 6 through a second conduit. The end of the conversion part 27 is connected to the fan through an air inlet pipe, and a pressure relief valve is provided on the air inlet pipe.

[0051] The principles and beneficial effects of the above scheme are:

[0052] When the operator places the paper to be printed, the bottom surface of the paper to be printed is in contact with the top surface of a guide seat 24, and the conversion member 27 controls the duct to supply air to the air guide hole, and the air guide hole supplies air to the multiple exhaust holes 25. The end of the paper to be printed is subjected to the pressure of the air flow, and the end of the paper to be printed is blown, and the top surface of the paper to be printed contacts the bottom surface of the buffer plate 26. By providing the exhaust holes 25, the exhaust holes 25 use the pressure generated by the air flow to lift the end of the paper to be printed upward, so as to accurately guide the paper to be printed; by providing the bottom surface of the buffer plate 26 to contact the top surface of the paper to be printed, the buffer plate 26 is connected to the mounting plate on the inner wall of the U-shaped frame 1 through multiple buffer springs to reduce the swing of the paper; the operator continues to move the paper to be printed, and after passing through the front pulling head 3, it enters the rear pulling head 4 through the guidance of another guide seat 24 and the buffer plate 26. By providing the guide seat 24 and the buffer plate 26, the difficulty of the operator in placing the paper to be printed is reduced;

[0053] At the same time, it avoids danger to the operator when placing the paper to be printed; by providing the exhaust hole 25, the air flow is used to guide the paper, which reduces the complexity of the structure. The device can be applied to a variety of different types of sliders, which improves the applicability of the device.

[0054] The air guide hole and the exhaust hole 25 in the guide seat 24 can be processed by drilling. When it is determined that the air guide hole is parallel to the upper and lower surfaces of the guide seat 24, the processing can be started. After the processing is formed, the exhaust hole 25 can be drilled in a direction perpendicular to the end surface of the guide seat 24. The processing is completed when the exhaust hole 25 is connected with the air guide hole, which reduces the assembly difficulty and processing cost.

[0055] When the thickness of the paper being transported is large and the mass is increased, the air flow of the exhaust holes 25 can be increased to guide the paper being transported.

[0056] By setting the guide seat 24 and the buffer plate 26 at a distance from each other, the contact area between the paper to be printed and the guiding device is reduced, avoiding excessive contact area with the guiding device, which causes the paper to be printed to be adsorbed on the guiding device, and prevents the paper to be printed from piling up during the prevention process, thereby destroying the integrity of the paper to be printed; at the same time, the guide seat 24 and the buffer plate 26 can replace ordinary guiding devices, and are suitable for conveying the paper to be printed at various angles, further improving the applicability of the device.

[0057] The conversion member 27 includes: a gear 28, a slider 29 and a conversion hole 30. The top of the ruler rod 15 is provided with a mounting opening, and a gear 28 is provided in the mounting opening. The gear 28 is connected to the end of a roller 16, and the bottom of the mounting opening is connected to a slide. The inner wall of the slide is connected to the side wall of the slider 29 through a second return spring. The rack on the top surface of the end of the slider 29 is meshed with the gear 28. The slider 29 is provided with a conversion hole 30 and a second conversion hole. The conversion hole 30 and the second conversion hole have the same structure. The front end diameter of the conversion hole 30 is smaller than the rear end diameter thereof. The front end of the conversion hole 30 is connected to the end of the conduit, and the second conversion hole is staggered with the end of the second conduit. The rear end of the conversion hole 30 faces the air guide groove on the side wall of the slide, and the side wall of the air guide groove is connected to the end of the intake pipe.

[0058] An air inlet 32 ​​is provided at one end of the hollow slider roller 6, which is rotatably connected to the end of the second conduit. A plurality of air outlet holes 34 facing the motor are provided at the other end of the hollow slider roller 6, and a plurality of heat conducting plates 33 are equidistantly installed on the inner wall of the hollow slider roller 6.

[0059] The principles and beneficial effects of the above scheme are:

[0060] When the paper to be printed is placed, the conversion hole 30 is connected to the end of the duct, and the conversion member 27 is connected to the fan through the air inlet pipe. The air inlet pipe supplies air to the conversion hole 30, and the conversion hole 30 supplies air to the guide seat 24 through the duct to guide the paper to be printed. When the paper to be printed is placed, the device is started, and the paper to be printed begins to move toward the printing mechanism. When the bottom surface of the paper to be printed is frictionally matched with the side wall of the roller 16, the gear 28 connected to the end of one roller 16 rotates forward, and the forward rotation of the gear 28 drives the rack at the top of the slider 29 to move. The slider 29 compresses the second return spring, and the conversion mechanism is turned on. The hole 30 is disconnected from the communication with the conduit, and the second conversion hole on the slider 29 is connected to the second conduit. The second conduit supplies air to the rotating hollow slider roller 6. By providing an air inlet 32 ​​at one end of the hollow slider roller 6 and a plurality of air outlet holes 34 at the other end of the hollow slider roller 6, the hollow slider roller 6 can be cooled to prevent the rubber coated on the side wall of the hollow slider roller 6 from melting due to long-term friction, resulting in contamination of the paper to be printed, and preventing the heat-denatured rubber from sticking to the paper to be printed, thereby preventing the paper to be printed from deforming during transportation, thereby increasing the long-term working effect of the hollow slider roller 6.

[0061] By arranging the air outlet 34 toward the motor, the motor can be cooled during the operation of the device, thereby increasing the service life of the motor and reducing the setting of the cooling device, thereby reducing the cost of the device production; a plurality of heat conducting plates 33 are arranged on the hollow slider roller 6, which further increases the cooling effect of the device; the cross-section of the air inlet 32 ​​is larger than the cross-section of the air outlet 34, and when the air flow enters the hollow slider roller 6, the air flow rate slows down, which is convenient for the air to fully contact with the hollow slider roller 6 and absorb the heat generated by the device. After the air flow flows out of the air outlet 34, the flow rate increases, which is convenient for quickly dissipating the temperature in the device. The air flow after dissipating the heat contacts the external air to cool the motor, thereby further improving the cooling effect of the device;

[0062] An air guide groove is opened on the side wall of the slide, and the air guide groove is connected to the air inlet pipe. The cross-sectional area of ​​the air guide groove is larger than the cross-sectional area of ​​the conversion hole 30 and the second conversion hole. The cross-sectional area of ​​the front end of the conversion hole 30 is smaller than the cross-sectional area of ​​the rear end. When the slider 29 moves the compression spring, the axis of the conversion hole 30 is perpendicular to the other side wall of the slide. The position of the slider 29 is limited by the air pressure in the conversion hole 30 to prevent the device from resetting.

[0063] An intelligent control method for a slider for an intermittent printing press, applicable to any of the above-mentioned sliders for an intermittent printing press, comprises the following steps:
