Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for book trimmers, and more particularly to a tear-proof device for three-sided book trimmers. Background Technology

[0002] A book trimmer is a device used to cut the edges of printed books. A three-sided book trimmer is a type of book trimmer that cuts the rough edges on three sides of a book simultaneously and sequentially. The main types include semi-automatic, automatic, and double-sided trimmers.

[0003] A three-sided book cutter is equipped with three sets of blades to continuously cut the three sides of a book (excluding the book cover) to achieve neat book appearance.

[0004] To improve book cutting efficiency, books are stacked and fixed at one time before being cut by a three-sided book cutter. If the thickness of the stacked books reaches a certain size, the cutting surface of the book edges is prone to tearing. This is because as the thickness of the books increases, their softness increases, and when the blade's downward pressure speed is inconvenient, cutting misalignment occurs, resulting in tearing. Simply increasing the linear impact speed of the blade will cause impact damage to the blade. Summary of the Invention

[0005] The purpose of this invention is to solve the following problems existing in the prior art: as the thickness of the book increases and its softness increases, when the blade's downward pressure speed is inconvenient, cutting misalignment will occur, forming a tear. Simply increasing the linear impact speed of the blade will cause impact damage to the blade.

[0006] To address the problems existing in the prior art, this invention provides a three-sided book trimmer anti-tear device, including a base plate, a pressure plate set on the edge of the base plate, a pressing component set on the upper part of the base plate to drive the pressure plate to rise and fall, the pressure plate and the base plate being connected by a guide component, the guide component including a rack linearly distributed on the surface of the base plate, the rack meshing with a gear, the gear rotating through the pressure plate to fix an eccentric roller, a movable plate vertically sliding on the surface of the pressure plate, a limit opening opened on the surface of the movable plate, the eccentric roller being adapted to the limit opening, and a blade being fixedly installed on the surface of the movable plate.

[0007] Preferably, the limiting movable opening is elliptical, and the minimum diameter of the limiting movable opening is the same as the diameter of the eccentric roller.

[0008] Preferably, the guide assembly further includes a groove formed on the surface of the base plate, a slider sliding in the groove, the rack being placed at the edge of the groove, and the gear being rotatably connected to the slider.

[0009] Preferably, the pressing assembly includes a strip plate, the pressure plate slides horizontally with the strip plate, a telescopic cylinder is installed on the surface of the base plate, the telescopic end of the telescopic cylinder is connected to the strip plate, and a guide post slides vertically on the top of the base plate, the guide post being fixedly connected to the strip plate.

[0010] Preferably, the groove is inclined to guide the feed blade at an angle.

[0011] Preferably, the bottom of the pressure plate has a bonding portion, and the blade slides into contact with the bonding portion. The bonding portion is designed to counteract the shaking blade and keep the blade in a stable shape during high-speed cutting.

[0012] Preferably, the bonding part has an oil storage cavity inside, and the bottom surface of the bonding part has a hole that passes through the oil storage cavity. An elastic plate is fixed to the bottom of the bonding part. The elastic plate bends downward and points towards the cutting edge of the blade. Sponge is filled between the elastic plate and the blade. Through the elastic covering of the elastic plate, the sponge is attached to the surface of the blade. The outer side of the blade that vibrates at high frequency is in contact with the sponge and is coated with lubricating oil, which effectively improves the cutting sharpness.

[0013] Preferably, the bottom end of the elastic plate has a cylindrical portion that contacts the cutting edge of the blade. The cylindrical portion is used to scrape off the lubricating oil from the cutting edge of the blade, preventing oil from dripping from the bottom of the blade and making full use of the lubricating oil.

[0014] Compared with related technologies, the three-sided book trimmer anti-tear device provided by the present invention has the following beneficial effects:

[0015] 1. This invention installs the blade vertically and positions it by the contact between the eccentric roller and the limiting movable opening. During the book cutting process, the meshing of the rack and gear causes the eccentric roller to rotate eccentrically and squeeze the limiting movable opening, causing the blade to vibrate up and down at high frequency. The downward tilting motion of the blade as the cutting feed is achieved by the high frequency vibration of the blade, which enables rapid cutting of the book edge. The cutting speed is fast and effectively avoids tearing at the cut.

[0016] 2. The present invention uses an oil-soaked sponge, which, together with an elastic plate, elastically covers the blade to apply lubricating oil to the high-frequency vibrating blade, thereby maintaining the sharpness of the blade.

[0017] 3. The present invention provides a fitting part at the bottom of the pressure plate, so that the blade slides and fits into the fitting part. The blade edge at the bottom of the blade protrudes from the bottom of the fitting part. The fitting part is designed to resist the shaking blade, so that the blade maintains a stable shape during high-speed cutting, making thinner blades suitable for this device and improving cutting sharpness.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] Example 1

[0029] like Figure 7 As shown, the three-sided book cutter anti-tear device has three sets of base plates 1 set at the three edges of the cutting station. The base plates 1 extend vertically, and a pressure plate 4 is set on the side of the base plate 1 closest to the cutting station.

[0030] like Figure 3-4 As shown, the guide assembly includes a slide 9. Two slides 9 are opened on the surface of the base plate 1 and the slides 9 are inclined. A rack 10 is set on the edge of the slide 9. The slider 12 slides in the slide 9. The gear 11 is rotatably connected to the slider 12. The gear 11 is meshed with the rack 10. The shaft of the gear 11 rotates through the pressure plate 4 and is fixedly connected to the eccentric roller 8.

[0031] like Figure 1-4 As shown, the pressing assembly includes a strip plate 3, a pressure plate 4 and a strip plate 3 that slide horizontally through a rail and a guide block, two guide posts 18 that slide vertically on the top of the base plate 1, the guide posts 18 are fixedly connected to the strip plate 3, and a telescopic cylinder 2 is installed on the surface of the base plate 1, with the telescopic end of the telescopic cylinder 2 connected to the strip plate 3.

[0032] like Figure 4-5As shown, a movable plate 5 is set on the side of the pressure plate 4 near the cutting station. The movable plate 5 is vertically slidably connected to the pressure plate 4. Two elliptical limiting movable openings 7 are opened on the surface of the movable plate 5. An eccentric roller 8 is inserted into the limiting movable opening 7. The minimum diameter of the limiting movable opening 7 is the same as the diameter of the eccentric roller 8.

[0033] The blade 6 is attached to the side of the movable plate 5 near the cutting station and fixed with screws, with the cutting edge of the blade 6 at the bottom;

[0034] When cutting books, the telescopic cylinder 2 retracts, and the strip plate 3 descends under the guidance of the two guide pillars 18. At this time, the height of the pressure plate 4, the movable plate 5, and the blade 6 descends synchronously. Under the sliding guidance of the slider 12 and the slide groove 9, the pressure plate 4, the movable plate 5, and the blade 6 tilt downwards and approach the edge of the book. The pressure plate 4 and the strip plate 3 slide horizontally.

[0035] The gear 11 is meshed with the rack 10, which drives the eccentric roller 8 to rotate. The eccentric roller 8 eccentrically squeezes and limits the movable port 7, causing the movable plate 5 to drive the blade 6 to move up and down at high frequency and vibrate. When the blade 6 contacts the edge of the book, the blade 6 tilts downward as the cutting feed. The high-frequency vibration of the blade 6 enables rapid cutting of the edge of the book. The cutting speed is fast and effectively avoids the breakage at the cut.

[0036] Cut the book from both ends, then cut the other side;

[0037] Example 2

[0038] A pressure plate 4 is installed on the side of the base plate 1 near the cutting station;

[0039] The guide assembly includes a slide 9. Two slides 9 are opened on the surface of the base plate 1 and the slides 9 are inclined. A rack 10 is set on the edge of the slide 9. The slider 12 slides in the slide 9. The gear 11 is rotatably connected to the slider 12 and meshes with the rack 10. The shaft of the gear 11 rotates through the pressure plate 4 and is fixedly connected to the eccentric roller 8.

[0040] The pressure plate 4 and the strip plate 3 slide horizontally through the rail and guide block. Two guide posts 18 slide vertically on the top of the base plate 1. The guide posts 18 are fixedly connected to the strip plate 3. The telescopic cylinder 2 is installed on the surface of the base plate 1. The telescopic end of the telescopic cylinder 2 is connected to the strip plate 3.

[0041] A movable plate 5 is set on the side of the pressure plate 4 near the cutting station. The movable plate 5 is vertically slidably connected to the pressure plate 4. Two elliptical limiting movable openings 7 are opened on the surface of the movable plate 5. An eccentric roller 8 is inserted into the limiting movable opening 7. The minimum diameter of the limiting movable opening 7 is the same as the diameter of the eccentric roller 8.

[0042] The blade 6 is attached to the side of the movable plate 5 near the cutting station and fixed with screws, with the cutting edge of the blade 6 at the bottom;

[0043] The difference from Example 1 is:

[0044] like Figure 4-5 As shown, a bonding part 17 is provided at the bottom of the pressure plate 4. The thickness of the bonding part 17 increases towards the cutting station, so that the blade 6 slides and bondes with the bonding part 17. The blade edge at the bottom of the blade 6 protrudes from the bottom of the bonding part 17.

[0045] The fitting part 17 is designed to counteract the vibration of the blade 6, so that the blade 6 maintains a stable shape during high-speed cutting, making the thinner blade 6 suitable for this device and improving the cutting sharpness.

[0046] like Figure 4-6 As shown, an oil storage cavity 14 is opened inside the fitting part 17, and an opening for adding lubricating oil into the oil storage cavity 14 is provided on the side of the fitting part 17. A hole is opened on the bottom surface of the fitting part 17 to pass through the oil storage cavity 14. A plastic elastic plate 13 is fixed to the bottom of the fitting part 17. The elastic plate 13 is bent downwards towards the blade part of the blade 6. A sponge 15 is placed between the elastic plate 13 and the blade 6 and fixed to the elastic plate 13.

[0047] The lubricating oil in the oil storage cavity 14 seeps into the interior of the sponge 15. Through the elastic wrapping of the elastic plate 13, the sponge 15 adheres to the surface of the blade 6. The outer side of the high-frequency vibrating blade 6 contacts the sponge 15 and is coated with lubricating oil, which effectively improves the cutting sharpness. The side coated with lubricating oil contacts the cut-off residue and does not come into contact with the book.

[0048] A cylindrical part 16 is integrally fixed at the bottom end of the elastic plate 13. The cylindrical part 16 contacts the cutting edge of the blade 6. The cylindrical part 16 is used to scrape off the lubricating oil from the cutting edge of the blade 6, so as to avoid oil dripping from the bottom of the blade 6 and make full use of the lubricating oil.
