Operation and problems of the hottest zxjd440a pap

Operation and problem analysis of zxjd440a paperback binding automatic line (II)

3 Problems and solutions in binding production

(1) round back

① the book position in the book clip is high, and the position of the supporting plate is improved

② if the slotting cutter is too high, lower the position of the slotting cutter head

③ the book post colliding table is too low, and the position of the supporting plate is raised

(2) the book cover is folded or misaligned

① the book position in the book clip is high, and the position of the supporting plate is raised

② if the slotting cutter is too high, lower the position of the slotting cutter head

③ if the glue temperature is too low, increase the glue temperature

④ glue is left in the glue homogenizing rod, which indicates that the heating pipe in the glue homogenizing rod is broken. Replace it and adjust the gap between the glue homogenizing rods

⑤ if the binding speed is too fast, adjust the binding speed and cutting time

(3) starting line

① the book position in the book clip is low, and the position of the supporting plate is lowered

② the slotting cutter is too low, so raise the position of the slotting cutter head

③ the side clamping tool distance is too large, and the position of the clamping plate between the sides is loosened outward

④ the book post is too high, and the position of the supporting plate is reduced

(4) the glue is honeycomb

① the book position in the book clip is high, and the position of the supporting plate is improved

② the glue temperature is too low, adjust the glue temperature

③ if the temperature of the homogenizing stick is too low, increase the temperature of the homogenizing stick

④ the supporting plate is too low, so raise the position of the supporting plate

(5) crack or squeeze

① the book position in the book clip is low and the supporting position is lowered

② the pressure of the upper sealing drum is too high, so ensure that there is a distance of 9mm between the upper plane of the drum and the bottom plane of large-scale investment of lithium battery downstream of the book clip

③ if there is too much glue on the upper rubber wheel 1, reduce the gap between the upper rubber wheel 1 and the rubber scraper

④ if the pressure of upper rubber wheel 1 is too high, lower the position of upper rubber wheel 1

(6) split the front of the book and turn it over

① passivate the cutting edge of the milling back knife and grind the milling back knife

② the back milling cutter support disc is not adjusted properly, so readjust it

(7) the outer edge of the large plane of the book clip body is rough

① the back milling cutter support disc is not adjusted properly, and it should be readjusted

② the support plate of slotting knife is not adjusted properly, and it should be readjusted

(8) wide book back

① the slotting knife support plate is not aligned with the large plane of the book clip body, readjust it

② it provides a strong guarantee for the rapid development of enterprises with independent innovation ability and intellectual property rights in the future. The pressure of the upper sealing drum is too high and the position of the drum is reduced

③ if the pressure of the upper rubber wheel is too high, lower the position of the upper rubber wheel 1

(9) uneven glue film

① the height and inner and outer positions of the side glue and primer devices are not adjusted well, so they should be readjusted

② the gap between the rubber scraper and the wheel bar is not adjusted well, so readjust it

(10) the back glue layer is wedge-shaped

① the glue bar is not parallel to the bottom plane of the book clip, adjust its parallelism

② the supporting plate is not parallel to the bottom plane of the book clip, and it should be readjusted

(11) uneven adhesive layer

① the distance between the uniform glue stick and the book block is not accurate, and the setting of the dot gate is fast and the adjustment is appropriate

② if the glue on the glue homogenizing stick is not scraped, adjust the rubber scraping plate to zero distance

③ it is difficult to repair the rubber homogenizing rod with cushion

④ the glue bar is not parallel to the back of the book, and can be slightly adjusted to the other side

(12) there is a gap in the adhesive layer

① there is too little glue in the primer device, so add an appropriate amount of glue

② the glue temperature is too low, adjust the glue temperature

(13) the positioning of the book cover is offset, and the cover conveying guide rail chain is not aligned. Readjust it

(14) the positive and penultimate pages are not firmly adhered

① the hot melt adhesive cannot meet the quality requirements of books and periodicals binding. It is required to use adhesive backing with good affinity and permeability

② the method is incorrect, such as the adhesive layer is too thick. Use glue and control the glue layer as required. The glue temperature is too high and drops to about 160 ℃ as required by the manual

③ the depth of milling back is shallow, which should reach 2 ~ 3mm to milling. The mechanical adjustment is improper, and the movement gap of the supporting platform is reduced, so that the rubber wheel is parallel to the rubber roller and the back of the book, and the rubber is evenly applied

4. Strict production arrangement and operation requirements to ensure quality

(1) put the opponent who has bound the pages into the page distribution station, and hang a quality tracking board to prevent the generation of wrong books. Sample production on each posting platform; For the first few books produced in each shift, the captain of the main engine should comprehensively check the quality of milling back, roughening, gluing and packaging of the books, and send them to the quality inspection team on duty after checking the samples one by one. Full time quality inspectors should conduct a comprehensive pre production inspection on the quality of the book. Find hidden dangers from the gross samples, transmit them to each production station, and overcome them in operation. The full-time quality inspectors of each shift shall check the binding and cutting quality in batches according to the output during the production process, and make records

(2) the first inspector on the production line of each shift should check the quality of the gross envelope and the number of Posts every five, focusing on checking the neat side folding marks, and putting an end to the phenomenon of wrong posts, no posts, etc. The second book checker at the bridge is also 5 books, staggered by oneortwo stations, focusing on the side glue, and rechecking the work of the first book checker. Finally, the inspector of the three side knife book should make the final inspection of the whole book and make the inspection number
