Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment design, and in particular to a device and method for pre-adjusting a slitting ridge roller of a web paper form printing machine. Background Art

[0002] The function of the ridge is to divide a continuous 12-inch sheet of paper into four or three-point tear lines, which are used to tear the invoice after it is printed. In the printing of form machines, the ridge operation is performed by the same size ridge roller with different slits. In actual production, the most common specifications are divided into three or four 12-inch sections.

[0003] The ridge production process on a form printing press is the final, critical step in each machine's operation. The ridge rollers are subject to intermittent dynamic loads during operation, resulting in a high failure rate, a significant bottleneck in production. Repairs to the ridge rollers follow the original manufacturer's procedures, but each repair and commissioning takes 6-8 hours. Repair testing and adjustment of the bidirectional play require 4-10 kg of paper, resulting in significant maintenance costs and a long maintenance period.

[0004] In order to solve the constraints of ridge roller maintenance on production, it is necessary to improve the maintenance process of the ridge roller of the tabulating machine and explore new maintenance process equipment. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a pre-adjustment device for the slitting ridge roller of a web paper form printing machine, which reduces maintenance time and testing consumption through the implementation of a new process.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A pre-adjusting device for the slitting ridge roller of a roll paper form printing machine includes a ridge roller, a transmission mechanism and a fastening mechanism. The ridge roller is connected to the transmission mechanism through bolts, and the ridge roller is connected to the fastening mechanism through bearing rolling. It also includes a pre-adjusting mechanism. The pre-adjusting mechanism includes wall panels and support connecting rods. The two wall panels are symmetrically arranged below the fastening mechanism and are threadedly connected through the support connecting rod; a positioning groove is opened above the wall panel, and the lower end of the fastening mechanism is embedded in the positioning groove; the lower end of the fastening mechanism is also connected to the two sides of the ridge roller with a connecting positioning rod for adjusting the position of the ridge roller, and the connecting positioning rod is connected to the fastening mechanism at both ends of the ridge roller.

[0008] The surface of the ridge roller is provided with a main groove, two rows of three-part grooves and three rows of four-part grooves along the axial direction; the three-part grooves are distributed on the surface of the ridge roller in three equal parts with the main groove, and the four-part grooves are distributed on the surface of the ridge roller in four equal parts with the main groove; it also includes a slitting knife, a pressure plate and fixing screws respectively installed in the main groove and the two rows of three-part grooves or the three rows of four-part grooves; the pressure plate presses the slitting knife on the same side of the main groove and the two rows of three-part grooves or the three rows of four-part grooves and fixes it through a fixing screw vertically arranged on the other side of the pressure plate; the two rows of three-part grooves or the three rows of four-part grooves are also provided with threaded holes for fixing the knife groove filling strips.

[0009] The transmission mechanism is a gear connected to one end of the ridge roller by bolts; the fastening mechanism includes a support seat and a bearing arranged at both ends of the ridge roller, the support seat is connected to the ridge roller through the bearing, and the lower end of the support seat is embedded in the positioning groove.

[0010] The transmission mechanism and fastening mechanism also include stop nuts arranged on the outside of the bearings at both ends of the ridge roller. A gear is also connected to the outside of the stop nut at one end of the ridge roller. Mounting rings are also provided at both ends of the top of the support seat, and fixing bolts are also provided at the four corners of the top of the support seat.

[0011] Furthermore, the bearing is a tapered roller bearing.

[0012] The steps for pre-adjusting the slitting ridge rollers of a web-fed form printing machine are as follows:

[0013] 1. Adjusting the pre-adjusting device for the slitting ridge roller of the web-fed form printing machine according to the actually measured data of the ridge station of the form printing machine, including dimensions, component distances, and precision error parameters;

[0014] Second, the corresponding average error value of the ridge line station of the table printing machine and the axial and circumferential runout value of the ridge line roller invention 1 are calculated based on the present invention;

[0015] 3. Use the data measured by the present invention to test and design the optimal trajectory of paper running between the intermediate tension system and the coding platform, ensure that the paper in the coding area is stable, measure the bidirectional runout of the ridge line roller invention 1, pre-install the ridge line roller invention 1, and debug the pre-installed value;

[0016] 4. According to the pre-measured bidirectional runout of the ridge roller 1 and the pre-installed value of the debugging, the ridge roller 1, the transmission mechanism and the fastening mechanism are actually installed.

[0017] The beneficial effects of the present invention are:

[0018] 1. Use a simulated ridge roller installation platform as a maintenance and assembly platform and a debugging benchmark to achieve offline maintenance and installation, as well as bidirectional clearance pre-commissioning. This simulated ridge roller installation platform is surveyed and machined to serve as a maintenance and assembly platform and debugging benchmark, enabling offline installation and commissioning. Statistical data on the pressure clearance values ​​of the ridge rollers on each machine are compiled, and pre-adjustments are performed on the simulated platform to ensure that on-machine testing passes the test on the first try.

[0019] 2. After installing and pre-adjusting the simulated ridge roller mounting platform, the machine can achieve an 80% success rate in direct production, and fine-tuning can achieve a 100% success rate in meeting production requirements. This significantly reduces equipment maintenance and commissioning time, reduces equipment consumption, and increases equipment production capacity. The simulated ridge roller mounting platform installation and pre-adjustment improves maintenance and installation accuracy, reduces spare parts consumption, and reduces the ridge roller failure rate by 20%, significantly increasing the company's form and bill printing capacity.

[0020] 3. The ridge roller is 12 inches and can be divided into three parts and four parts on the same roller. It can realize the operation of dividing the production into three parts and four parts on the same roller. When switching the divisions, there is no need to replace the ridge roller. You only need to adjust the position of the two slitting knives. There is no need to adjust the slitting pressure, installation, etc., which realizes the operation of dividing the production into three parts and four parts on the same roller and quick switching.

[0021] 4. Use filler strips to secure the vacant cutter grooves, eliminating circular runout and noise caused by dynamic balancing. No adjustments are required for slitting pressure and installation accuracy. Quickly switch between three and four operations, improving operational efficiency and reducing production costs, even reducing the purchase cost of a single set of ridge rollers.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] refer to Figures 1 to 3 ; A pre-adjustment device for the slitting ridge roller of a roll paper form printing machine, comprising a ridge roller 1, a transmission mechanism and a fastening mechanism, the ridge roller 1 being connected to the transmission mechanism by bolts, the ridge roller 1 being connected in a rolling manner in the fastening mechanism by bearings, and also comprising a pre-adjustment mechanism, the pre-adjustment mechanism comprising a wall panel 15 and a support connecting rod 14, the two wall panels 15 being symmetrically arranged below the fastening mechanism and being threadedly connected through the support connecting rod 14; a positioning groove 16 being provided above the wall panel 15, the lower end of the fastening mechanism being embedded in the positioning groove 16; the lower end of the fastening mechanism being close to both sides of the ridge roller 1 is also connected with a connecting positioning rod 13 for adjusting the position of the ridge roller 1, the connecting positioning rod 13 being connected to the fastening mechanisms at both ends of the ridge roller 1.

[0031] refer to Figures 4 and 5 The surface of the ridge roller 1 is axially defined by a main groove 101, two rows of three-dividing grooves 102, and three rows of four-dividing grooves 103. The three-dividing grooves 102 are distributed along the surface of the ridge roller 1 in equal thirds, similar to the main groove 101, while the four-dividing grooves 103 are distributed along the surface of the ridge roller 1 in equal fourths. The 12-inch three-dividing four-dividing roller technology utilizes the existing 12-inch four-dividing ridge roller design. The main groove 101 of the 12-inch three-dividing ridge roller 1 remains unchanged. Two three-dividing grooves 102 are cut 120° apart along the circumference, starting from the main groove 101. The three-dividing grooves 102 are machined with equal-sized slitting grooves in both a clockwise and counterclockwise direction. This allows a single 12-inch ridge roller 1 to simultaneously have both 12-inch three-dividing and 12-inch four-dividing grooves. In other words, six slitting grooves on a single ridge roller can achieve either three-dividing or four-dividing functions.

[0032] refer to Figure 4The present invention also includes a slitting knife 2, a pressure plate 3 and a fixing screw 4 respectively installed in the main groove 101 and the two rows of three-divided grooves 102 or the three rows of four-divided grooves 103; the pressure plate 3 presses the slitting knife 2 on the same side of the main groove 101 and the two rows of three-divided grooves 102 or the three rows of four-divided grooves 103 and fixes it by a fixing screw 4 vertically arranged on the other side of the pressure plate 3.

[0033] Design and manufacture three slit filler strips made of the same material as the ridge roller 1. The filler strips and the slits should be of the same size and precision. Design and manufacture two Ø6.2mm countersunk holes, centered 160mm on either side of the axial centerline of the filler strip. Ensure a tight fit between the filler strips and the slit slits. Threaded holes 104 are also provided within the two-row, three-division slots 102 or three-row, four-division slots 103 to secure the filler strips.

[0034] The ridge roller is 12 inches and can be divided into three parts and four parts on the same roller. It can realize the production of three parts and four parts on the same roller. When switching the fractions, there is no need to replace the ridge roller. You only need to adjust the position of the two slitting knives. There is no need to adjust the slitting pressure, installation, etc., which realizes the production of three parts and four parts on the same roller and quick switching.

[0035] The size of the threaded holes 104 processed corresponding to the six switchable slitting grooves on the ridge roller 1 is M6×10.

[0036] refer to Figures 1 to 3 The transmission mechanism is a gear 10 connected to one end of the ridge roller 1 by bolts, and the gear 10 is connected to an electric motor or other power device; the fastening mechanism includes a support seat 5 and a bearing 6 arranged at both ends of the ridge roller 1, and the support seat 5 is connected to the ridge roller 1 through the bearing 6, and the lower end of the support seat 5 is embedded in the positioning groove 16.

[0037] refer to Figures 1 to 3 The fastening mechanism also includes a stop nut 11 arranged on the outside of the bearing 6 at both ends of the ridge roller 1. A gear 10 is also connected to the outside of the stop nut 11 at one end of the ridge roller 1. Mounting rings 9 are also provided at both ends of the top of the support seat 5, and fixing bolts 7 are also provided at the four corners of the top of the support seat 5.

[0038] The threaded hole 104 is used to fix the steel bar. When a set of cutting grooves is not in use, a filler bar is used to compensate for the dynamic balance:

[0039] When using a 12-inch three-quarter ridge roller, a filler strip is installed in the quartered groove 103 to ensure smooth operation of the ridge roller and eliminate circular runout and noise caused by dynamic balancing.

[0040] When using a 12-inch quartered ridge roller, install a filler strip in the quartered slot 102 to eliminate circular runout and noise caused by dynamic balancing. Ensure that the ridge roller runs smoothly.

[0041] Filler bars are fixed in the vacant cutter grooves to eliminate circular runout and noise caused by dynamic balancing. Adjustments to slitting pressure and installation accuracy are no longer necessary. Quickly switch between three and four operations, improving operational efficiency and reducing production costs, including the purchase cost of a single set of ridge rollers.

[0042] refer to Figure 6 A web form printing machine is provided with the web form printing machine slitting ridge roller of the present invention, and the web form printing machine slitting ridge device of the present invention is used for pre-debugging.

[0043] The function of the 12-inch four-ridge roller in the printing press is to divide the continuous 12-inch long paper into 4 equal tear lines. After the invoice is continuously printed, it can be torn along the tear line.

[0044] The function of the 12-inch three-ridge roller in the printing press is to divide the continuous 12-inch long paper into three equal tear lines. After the invoice is continuously printed, it can be torn along the tear line.

Use the present invention to test and design the optimal trajectory of paper running between the intermediate tension system and the coding platform, ensure that the paper in the coding area is stable, measure the bidirectional runout of the ridge roller 1, pre-install the ridge roller 1, and debug the pre-installed value.

[0050] 4. Through multiple pre-installation tests, summarize the installation method of tapered roller bearing 6 and form a fixed installation platform and pre-installation data.

[0051] By using a simulated ridge roller installation platform as a maintenance and assembly platform and a benchmark for debugging, offline maintenance and installation, as well as bidirectional clearance pre-commissioning, can be achieved. By mapping and machining a simulated ridge roller installation platform as a maintenance and assembly platform and a benchmark for debugging, offline installation and debugging can be achieved. The pressure clearance values ​​of the ridge rollers on each machine are calculated and pre-adjusted on the simulated platform to ensure that the machine tests are generally passed on the first try.

[0052] After installing and pre-adjusting the simulated ridge roller mounting platform, the machine can achieve an 80% success rate in direct production, and fine-tuning can achieve a 100% success rate in meeting production requirements.
