Description

Technical Field

[0001] This utility model relates to the technical field of cardboard cutting devices, specifically a continuous cardboard cutting mechanism with waste collection function. Background Technology

[0002] As is well known, cardboard needs to be cut during production and processing. Nowadays, continuous cutting machines are commonly used to perform continuous cutting operations on cardboard.

[0003] For example, the utility model patent with application publication number CN221111968U, application publication date June 11, 2024, and title "A Continuous Digging Mechanism for Cardboard Cutting", has a specific structure of the cutting mechanism including a base plate, a storage groove at the upper end of the base plate, sliding grooves on both the front and rear sides of the storage groove, a pusher plate slidably connected inside the two sliding grooves, and two symmetrically distributed sliding rods fixedly connected to the left end of the pusher plate.

[0004] The shortcoming of the existing technology is that the cardboard is horizontally supported and conveyed by the pusher plate, and the cardboard is vertically reciprocated to continuously cut the cardboard. However, paper scraps are easily generated during the cardboard cutting process. As the cardboard contacts the cardboard for cutting, the paper scraps are easy to stick to the cutting edge of the cardboard, thus affecting the cutting effect of the cardboard. Utility Model Content

[0005] The purpose of this invention is to provide a continuous cardboard cutting mechanism with waste collection function to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous cardboard cutting mechanism with waste collection function, including a base and a conveyor belt fixedly mounted thereon, a cutting blade vertically slidably mounted on the base, and a mounting seat fixedly mounted on the base and parallel to the conveyor belt, a flipping plate oscillatingly mounted on the mounting seat, an adhesive tape being arranged on the flipping plate by a rotating roller, and the flipping plate flipping so that the end of the adhesive tape abuts against the side of the cutting blade.

[0007] As a further description of the above technical solution: the rotating roller is unidirectionally rotating and is mounted on the flipping plate.

[0008] As a further description of the above technical solution: the adhesive tape is fixedly provided with extensions arranged in an array at intervals. In the default state, the angle between the extensions and the adhesive tape surface is an acute angle, and the adhesive tape moves cyclically, causing the extensions to be squeezed and deformed by the cutting blade and move closer to the adhesive tape surface.

[0009] As a further description of the above technical solution: the first side of the extension is provided with a spaced array of wire grooves.

[0010] As a further description of the above technical solution: it also includes a rotating rod rotatably mounted on the mounting base, and a flow-driving fan for driving airflow to the cutting blade is fixedly mounted on the rotating rod.

[0011] As a further description of the above technical solution: the rotating rod is fixedly provided with overlapping parts arranged in a circumferential array, and the rotation of the rotating rod causes the overlapping parts to rotate circumferentially and the extension parts to deform away from the adhesive tape surface.

[0012] As a further description of the above technical solution: it also includes a collection box, on which a collection groove is provided, and the collection box is inserted and installed at the bottom of the collection groove.

[0013] As a further description of the above technical solution: the flip plate is made of Teflon.

[0014] As a further description of the above technical solution: the rotating rod is made of Teflon.

[0015] As a further description of the above technical solution: the collection box is made of stainless steel.

[0016] In the above technical solution, the present invention provides a continuous cardboard cutting mechanism with waste collection function. Utilizing a cleaning component set on the mounting base, when the cutting blade slides vertically close to the conveyor belt for the cutting stroke, the cutting edge of the cutting blade passes over the flip plate to contact the conveyor belt. When the cutting blade slides vertically away from the conveyor belt for the reset stroke, the adhesive tape will scrape the side of the cutting blade and the cutting edge, thereby scraping off paper scraps on the cutting edge or side of the cutting blade, preventing paper scraps from sticking to the cutting blade and affecting the cutting effect.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a continuous cardboard cutting mechanism with waste collection function, including a base 1 and a conveyor belt 2 fixedly disposed thereon, a cutting blade 3 vertically slidably disposed on the base 1, and a mounting seat 4 fixedly disposed on the base 1 and parallel to the conveyor belt 2, a flipping plate 51 oscillatingly disposed on the mounting seat 4, an adhesive tape 53 disposed on the flipping plate 51 by a rotating roller 52 arranged by rotation, the flipping plate 51 flipping so that the end of the adhesive tape 53 abuts against the side of the cutting blade 3.

[0027] Preferably, the conveyor belt 2 is used to transport the cardboard to be cut, and a drive cylinder 9 is fixedly installed in the base 1 to drive the cutting blade 3 to slide vertically. The mounting base 4 is welded to the base 1. When the conveyor belt 2 moves in a cycle, the cardboard moves towards the cutting blade 3 between the conveyor belt 2 and the mounting base 4. The mounting base 4 is provided with a flip plate 51, rotating rollers 52 and adhesive tape 53 to form a cleaning assembly 5. Two rotating rollers 52 are rotatably mounted on the flip plate 51, and the adhesive tape 53... Simultaneously, the adhesive tape 53 is fitted onto two adhesive tapes 53. When the cutting blade 3 slides vertically close to the conveyor belt 2 for the cutting stroke, the blade of the cutting blade 3 passes over the flip plate 51 to contact the conveyor belt 2. When the cutting blade 3 slides vertically away from the conveyor belt 2 for the reset stroke, the adhesive tape 53 scrapes against the side of the cutting blade 3 and the blade, thereby scraping off paper scraps on the blade or side of the cutting blade 3, preventing paper scraps from sticking to the cutting blade 3 and affecting the cutting effect. Furthermore, the rotating roller 52 can also drive the adhesive tape 53 to circulate, thereby improving the adhesion and cleaning effect on the cutting blade 3.

[0028] Among them, a worm spring is provided in the mounting base 4 to drive the flip plate 51 to swing closer to the cutting blade 3. Secondly, the drive cylinder 9 is common knowledge to those skilled in the art and will not be described in detail here.

[0029] In the above technical solution, using the cleaning component 5 installed on the mounting base 4, when the cutting blade 3 slides vertically close to the conveyor belt 2 for the cutting stroke, the blade of the cutting blade 3 passes over the flip plate 51 to contact the conveyor belt 2. When the cutting blade 3 slides vertically away from the conveyor belt 2 for the reset stroke, the adhesive tape 53 scrapes against the side of the cutting blade 3 and the blade, thereby scraping off paper scraps on the blade or side of the cutting blade 3, preventing paper scraps from sticking to the cutting blade 3 and affecting the cutting effect. Furthermore, the rotating roller 52 can also drive the adhesive tape 53 to circulate, improving the adhesion and cleaning effect on the cutting blade 3.

[0030] In another embodiment of this utility model, the rotating roller 52 is unidirectionally rotated on the flip plate 51.

[0031] Preferred, such as Figure 5 As shown, the rotating rollers 52 are all unidirectionally rotated clockwise on the flip plate 51, so that the adhesive tape 53 sleeved on the rotating rollers 52 can only move clockwise in a cyclical manner. When the cutting blade 3 slides vertically close to the conveyor belt 2 to perform the cutting stroke, the blade of the cutting blade 3 passes over the flip plate 51 to abut against the conveyor belt 2, and the cutting blade 3 drives the adhesive tape 53 to move clockwise in a cyclical manner through friction, thereby avoiding excessive resistance from the adhesive tape 53 to the cutting blade 3 and improving the cutting stability of the cutting blade 3.

[0032] When the cutting blade 3 slides vertically away from the conveyor belt 2 to complete its reset stroke, the adhesive tape 53 cannot rotate counterclockwise and is locked. At this time, the end of the adhesive tape 53 scrapes against the side of the cutting blade 3 and the cutting edge, thereby scraping off the paper scraps on the cutting edge or the side of the cutting blade 3, so that the adhesive tape 53 stops scraping against the cutting blade 3 to improve the cleaning effect on the cutting blade 3.

[0033] The rotating plate 51 is equipped with a pawl, and the rotating roller 52 is provided with a circumferential array of ratchet grooves. The pawl and ratchet grooves are used to realize the unidirectional rotation of the rotating roller 52.

[0034] In another embodiment of the present invention, an extension portion 531 arranged in an intermittent array is fixedly provided on the adhesive tape 53. The angle between the extension portion 531 and the tape surface of the adhesive tape 53 is an acute angle in the default state, and the adhesive tape 53 moves cyclically so that the extension portion 531 is squeezed and deformed by the cutting blade 3 and moves closer to the tape surface of the adhesive tape 53.

[0035] Preferred, such as Figure 5As shown, the extension 531 and the adhesive tape 53 are integrally formed. When the cutting blade 3 slides vertically close to the conveyor belt 2 for cutting, the blade of the cutting blade 3 passes over the flip plate 51 to contact the conveyor belt 2. The cutting blade 3 drives the adhesive tape 53 to move clockwise in a circular motion through friction. At this time, the extension 531 is deformed by the cutting blade 3 and approaches the surface of the adhesive tape 53 during the movement.

[0036] Subsequently, when the cutting blade 3 slides vertically away from the conveyor belt 2 to complete its reset stroke, the adhesive tape 53 cannot rotate counterclockwise and is locked. At this time, the end of the adhesive tape 53 scrapes against the side of the cutting blade 3 and the cutting edge, thereby scraping off the paper scraps on the cutting edge or the side of the cutting blade 3. Meanwhile, the extension 531 on the lower side of the adhesive tape 53 has been deformed and reset, and the scraped paper scraps can enter the angle between the extension 531 and the adhesive tape 53, thereby achieving stable collection of the scraped paper scraps and preventing the paper scraps from falling back onto the cardboard product.

[0037] In another embodiment of the present invention, the first side of the extension 531 is provided with a spaced array of wire grooves 532.

[0038] Preferred, such as Figure 5 As shown, the side of the extension 531 facing away from the adhesive tape 53 is the first side. To reduce wear on the cutting blade 3 during the cutting operation and to slow down the surface corrosion rate of the cutting blade 3, a protective oil is usually coated on the surface of the cutting blade 3. However, during the punching process, the protective oil on the cutting blade 3 tends to accumulate and drip down onto the cardboard product. When the cutting blade 3 slides vertically close to the conveyor belt 2 for the cutting stroke, the blade of the cutting blade 3 passes over the flip plate 51 to contact the conveyor belt 2, and the cutting blade 3 drives the adhesive tape 53 to move clockwise in a circular motion through friction. At this time, the extension 531 is deformed by the cutting blade 3 and approaches the surface of the adhesive tape 53 during the movement. At this time, the extension 531 adheres the oil on the surface of the cutting blade 3 in a linear shape through several grooves 532, which alleviates the situation where the oil accumulates on the surface of the cutting blade 3 and drips down.

[0039] In another embodiment of the present invention, a rotating rod 7 is rotatably mounted on the mounting base 4, and a flow-driving fan 71 for driving airflow to the cutting blade 3 is fixedly mounted on the rotating rod 7.

[0040] Preferred, such as Figure 1As shown, the rotating rod 7 is rotatably mounted on the mounting base 4 to cause the drive fan 71 to rotate cyclically. The cyclic rotation of the drive fan 71 drives the airflow to the cutting blade 3 for cooling, preventing the cutting blade 3 from overheating and accelerating wear during the cutting operation, thus improving the protection of the cutting blade 3. A drive motor and transmission gear are installed inside the mounting base 4 to drive the rotating rod 7 to rotate cyclically.

[0041] In another embodiment of the present invention, overlapping portions 72 arranged in a circular array are fixedly provided on the rotating rod 7. The rotation of the rotating rod 7 causes the overlapping portions 72 to rotate circumferentially and causes the extension portion 531 to deform away from the adhesive tape 53 surface.

[0042] Preferred, such as Figure 5 As shown, during the cyclic rotation of the rotating rod 7, the rotating rod 7 also drives the overlapping part 72 to move circumferentially to deform the extension part 531. This deformation causes the extension part 531 to move away from the adhesive tape 53 surface, shaking off paper debris between the extension part 531 and the adhesive tape 53 surface into the mounting base 4, thus completing the collection of paper debris waste from the adhesive tape 53. The end of the overlapping part 72 is provided with an arched portion, and the extension part 531 has an inner groove. When the overlapping part 72 moves and presses against the extension part 531, the arched portion moves into the inner groove and applies a deformation pulling force to the extension part 531, thereby further improving the removal rate of paper debris from the adhesive tape 53.

[0043] In another embodiment of the present invention, a collection box 6 is also included. A collection groove 41 is provided on the mounting base 4, and the collection box 6 is inserted and installed at the bottom of the collection groove 41.

[0044] Preferred, such as Figure 5 As shown, the collection box 6 is inserted into the collection slot 41 and can be removed for cleaning. The collection box 6 is located on the vertically lower side of the rotating rod 7 and the cleaning component 5 to collect the paper scraps shaken off from the adhesive tape 53, thereby achieving stable collection of waste.

[0045] In another embodiment of this utility model, the flip plate 51 is made of Teflon.

[0046] Preferably, the flip plate 51 is made of Teflon to improve its wear resistance and compressive strength.

[0047] In another embodiment of this utility model, the rotating rod 7 is made of Teflon.

[0048] Preferably, the rotating rod 7 is made of Teflon to improve its wear resistance and compressive strength.

[0049] In another embodiment of this utility model, the collection box 6 is made of stainless steel.

[0050] Preferably, the collection box 6 is made of stainless steel to improve its corrosion resistance and compressive strength.

[0051] Working principle:

[0052] When the conveyor belt 2 moves in a cycle, the cardboard moves towards the cutter 3 between the conveyor belt 2 and the mounting base 4. When the cutter 3 slides vertically close to the conveyor belt 2 to perform the cutting stroke, the blade of the cutter 3 passes over the flip plate 51 to contact the conveyor belt 2. The cutter 3 drives the adhesive tape 53 to move clockwise in a cycle through friction. At this time, the extension 531 of the adhesive tape 53 is deformed by the cutter 3 and moves close to the tape surface of the adhesive tape 53 during the movement.

[0053] Subsequently, when the cutting blade 3 slides vertically away from the conveyor belt 2 to complete its reset stroke, the adhesive tape 53 cannot rotate counterclockwise and is locked. At this time, the end of the adhesive tape 53 scrapes against the side of the cutting blade 3 and the blade edge, thereby scraping off the paper scraps on the blade edge or side of the cutting blade 3. Meanwhile, the extension 531 on the lower side of the adhesive tape 53 has been deformed and reset, and the scraped paper scraps can enter the angle between the extension 531 and the adhesive tape 53. The fan 71 rotates in a cycle to drive the airflow to the cutting blade 3 for cooling. The rotating rod 7 also drives the overlapping part 72 to move circumferentially to deform the extension 531, thereby deforming the extension 531 away from the adhesive tape 53 to shake off the paper scraps between the extension 531 and the adhesive tape 53 into the collection box 6.

[0054] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
