Description

Technical Field

[0001] The invention relates to the technical field of cutting, and in particular to a corrugated cardboard cutting device and a method thereof. Background Art

[0002] Before corrugated cardboard is converted into a variety of packaging products, a series of pre-processing processes need to be performed, which includes a key step: size optimization cutting, which is also known as slitting in the industry. This step aims to accurately divide large pieces of corrugated cardboard into strips that meet the requirements of different packaging boxes and pallets, laying the foundation for the subsequent production of various packaging structures.

[0003] However, when implementing size-optimized cutting for corrugated cardboard, given the natural variability in the size of the raw cardboard, it is necessary to perform a knife calibration operation (ensuring that the blade and the edge of the cardboard are accurately matched) before each cutting start. This process is crucial to improving cutting accuracy. Traditionally, the calibration marks on the operating table are relied on to assist in alignment, but this method makes it difficult to achieve instant and efficient alignment between the cardboard and the marks, affecting production efficiency.

[0015] A method for cutting corrugated cardboard comprises the following steps:

[0016] S1, preparation stage: pull the working panel forward, ensure that the cutting knife is located at the rear side of the working panel, place the corrugated cardboard to be cut on the working panel, and ensure that one side of the corrugated cardboard is in contact with the slide plate;

[0017] S2, knife setting operation: controlling the electric slide rail to drive the slide plate to move through the slider, and the slide plate pushes the corrugated paperboard to move until the corrugated paperboard contacts the clamping frame;

[0018] S3, repeating the operation: intermittently pushing and pulling the working panel back and forth and intermittently controlling the electric slide rail to drive the corrugated paperboard to move the same distance to the side close to the cutting knife;

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] Before the corrugated cardboard is cut, when the working panel is pulled forward to place the corrugated cardboard, the clamping frame is automatically limited by the clamping block being clamped into the clamping slot, so that when the corrugated cardboard moves to the left to contact with the fixed clamping frame, the cutting knife can be automatically and firmly aligned quickly, and the clamping frame is automatically released when the working panel is pushed backward, which will not affect the subsequent strip cutting operation.

[0022] During the cutting process of the corrugated cardboard as the working panel moves back and forth relative to the cutting knife, the pressing frame maintains the state of pressing the corrugated cardboard down to prevent the corrugated cardboard from slipping relative to the working panel when it hits the cutting knife.

[0023] The present invention flexibly limits the right side edge of the corrugated paperboard through the positioning frame, and drives the clamping plate to move downward to clamp the positioning frame through the pressing frame, so as to fix the positioning frame. The positioning frame is locked, which can cope with the situation that the right side edge is not a right-angle edge, and avoid the corrugated paperboard shaking left and right during the subsequent cutting process, thereby avoiding affecting the cutting of the corrugated paper.

[0024] When the first spring of the present invention is compressed to the limit, the clamping frame no longer squeezes the pushing frame, and the second tension spring in the stretched state is reset to drive the pushing frame to slide forward, thereby pushing a cut corrugated paper strip forward, and the inclined surface of the pushing frame causes the rear end of the pushed corrugated paper strip to be pushed upward, so that the inclined corrugated paper strip is easier for people to take out.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: A corrugated cardboard cutting device, combined with the attached Figure 1 To Attachment Figure 4, including a cutting machine 1, a cutting knife 102 is installed on the left side of the cutting machine 1 through a knife holder, a working panel 2 is slidably connected to the middle part of the cutting machine 1 along the front-back direction, a corrugated cardboard 101 is placed on the right side of the working panel 2, and a plurality of round holes are opened on the working panel 2 for dropping the debris generated during cutting, an electric slide rail 3 symmetrically distributed along the front and back of the cutting machine 1 is fixedly connected to the right side of the cutting machine 1, a slider 4 is slidably connected to the electric slide rail 3 along the left-right direction, a slide plate 5 is fixedly connected between all the sliders 4, the bottom of the slide plate 5 contacts the top of the working panel 2, the right side of the corrugated cardboard 101 contacts the left side of the slide plate 5, a clamping frame 6 is slidably connected to the left side of the cutting machine 1 along the left-right direction, the knife holder of the cutting knife 102 is provided with an inclined surface for protecting the clamping frame 6, and when the cutting knife 102 trims the left side of the corrugated cardboard 101 The inclined surface of the knife holder of the cutting knife 102 squeezes the clamping frame 6 to the left to prevent the cutting knife 102 from cutting the clamping frame 6 by mistake. A first spring 7 symmetrically distributed along the front and back of the clamping frame 6 is fixedly connected between the clamping frame 6 and the cutting machine 1. A slide bar 8 is fixedly connected to the middle of the left side of the cutting machine 1. The slide bar 8 is provided with a convex surface symmetrically distributed along the slide bar 8. A guide plate 9 is fixedly connected to the left side of the bottom of the working panel 2. The guide plate 9 has a slide groove. The slide bar 8 horizontally penetrates the slide groove of the guide plate 9. The rear end of the slide groove of the guide plate 9 is set as an inclined portion. The inclined portion of the slide groove of the guide plate 9 moves and is squeezed and matched with the convex surface of the slide bar 8. Two clamping blocks 10 are slidably connected to one side of the working panel 2 close to the guide plate 9 along the front and rear directions. The clamping block 10 and the guide plate 9 are limited by the inclined plate. The clamping frame 6 has a slot 11 corresponding to the block 10, and the block 10 limits the clamping frame 6 through the slot 11.

[0037] First, pull the working panel 2 forward to the front, at which time the cutting knife 102 is at the rear, place the corrugated cardboard 101 to be cut on the working panel 2, and make the right side of the corrugated cardboard 101 contact the slide plate 5, then control the electric slide rail 3 to drive the slide plate 5 to move leftward through the slider 4, and the slide plate 5 pushes the corrugated cardboard 101 to move leftward until it contacts the clamping frame 6, thus realizing the knife alignment operation of the corrugated cardboard 101;

[0038] In the above-mentioned tool setting process, in order to prevent the corrugated paperboard 101 from pushing the clamping frame 6 to the left, resulting in tool setting errors, the clamping frame 6 needs to be fixed during tool setting. The specific operation is as follows:

[0039] When the working panel 2 is pulled forward to the front, the guide plate 9 moves forward together with the working panel 2 until the inclined portion of the guide plate 9 on the rear side of the slide groove contacts the left convex surface of the slide rod 8. The guide plate 9 moves to the right under the squeezing action of the left convex surface of the slide rod 8. The guide plate 9 squeezes the block 10 through the inclined plate and slides to the side away from the slide rod 8 until it is inserted into the slot 11, thereby fixing the clamp 6.

[0040] Then, the working panel 2 is pushed backward, and the corrugated paperboard 101 moves backward together with the working panel 2. During this process, the cutting knife 102 trims the left side of the corrugated paperboard 101, so that the left side of the corrugated paperboard 101 becomes regular and flat, and the inclined surface of the knife holder pushes the clamping frame 6 to the left to prevent the cutting knife 102 from cutting the clamping frame 6.

[0041] In the above process, the guide plate 9 moves backward together with the working panel 2, and the inclined portion on the rear side of the slide groove of the guide plate 9 contacts the right convex surface of the slide rod 8. Under the squeezing action of the right convex surface of the slide rod 8, the guide plate 9 moves to the left and resets. The guide plate 9 squeezes the block 10 through the inclined plate to slide to the side close to the slide rod 8 until it disengages from the slot 11, thereby releasing the fixation of the clamp 6.

[0042] Afterwards, the operation of pushing and pulling the working panel 2 back and forth is repeated intermittently. At the same time, the electric slide rail 3 is controlled to intermittently drive the corrugated cardboard 101 to move to the left by the same distance, and the clamping frame 6 is also intermittently squeezed to the left by the corrugated cardboard 101 and moved by the same distance. The first spring 7 is intermittently compressed to the same extent. In this way, the corrugated cardboard 101 can be continuously cut into corrugated paper strips of the same specifications during the forward and backward movement. After cutting, the corrugated paper strips are taken away, and the electric slide rail 3 is controlled to drive the slide plate 5 to move to the right and reset through the slider 4. The reset of the first spring 7 drives the clamping frame 6 to move to the right and reset.

[0043] To summarize, before the present invention starts cutting the corrugated cardboard 101, when the working panel 2 is pulled forward to place the corrugated cardboard 101, the clamping frame 6 is automatically limited by the clamping block 10 being clamped into the clamping slot 11, so that when the corrugated cardboard 101 moves to the left to contact with the fixed clamping frame 6, it can automatically and firmly align the cutting knife quickly, and when the working panel 2 is pushed backward, the clamping frame is automatically released, which will not affect the subsequent strip cutting operation.

[0044] Embodiment 2: Based on embodiment 1, Figure 5 To Attachment Figure 6 , also includes a pressing frame 12, the pressing frame 12 is slidably connected to the right side of the working panel 2 in the up and down direction, the rear side of the top of the pressing frame 12 is set as an inclined surface, and the front side is set as a plane. The pressing frame 12 is used to press the corrugated cardboard 101 onto the working panel 2, the pressing frame 12 is in contact with the cutting machine 1, and a first tension spring 13 symmetrically distributed along the front and back of the working panel 2 is fixedly connected between the pressing frame 12 and the working panel 2. An electromagnet 14 symmetrically distributed along the front and back of the working panel 2 is fixedly connected to the right side of the bottom of the working panel 2, and a magnetic block 15 corresponding to the electromagnet 14 is fixedly connected to the lower right side of the pressing frame 12. When power is turned on, the electromagnet 14 and the corresponding magnetic block 15 are magnetically matched.

[0045] In the cutting process where the corrugated cardboard 101 moves forward and backward with the working panel 2 relative to the cutting knife 102, in order to prevent the corrugated cardboard 101 from stopping when it hits the cutting knife 102, thereby causing the corrugated cardboard 101 to be displaced relative to the working panel 2, and then causing the corrugated cardboard 101 to be unable to move with the working panel 2 for cutting, it is necessary to press the corrugated cardboard 101 against the working panel 2. The specific operation is as follows:

[0046] When the working panel 2 moves forward to the frontmost side, the first tension spring 13 is in a natural state, the pressing frame 12 is in a high position, the corrugated cardboard 101 is placed on the working panel 2, so that the corrugated cardboard 101 is located below the pressing frame 12. When the working panel 2 moves backward, the cutting machine 1 first contacts the inclined surface of the pressing frame 12, and the pressing frame 12 slides downward, the first tension spring 13 is stretched, and the pressing frame 12 drives the magnetic block 15 to move downward until the cutting machine 1 contacts the plane of the pressing frame 12. At this time, the magnetic block 15 moves downward to the energized electric The magnets 14 are attracted to each other, and in the subsequent process of the working panel 2 moving back and forth, the cutting machine 1 maintains a planar contact with the pressing frame 12, so that the pressing frame 12 maintains a state of pressing down the corrugated cardboard 101, thereby preventing the corrugated cardboard 101 from slipping relative to the working panel 2 when it hits the cutting knife 102. After the cutting is completed, the electromagnet 14 is powered off, and when the working panel 2 drives the pressing frame 12 to move forward and disengage from the cutting machine 1, the first tension spring 13 is reset to drive the pressing frame 12 to slide upward, thereby driving the magnetic block 15 to move upward and disengage from the electromagnet 14.

[0047] Embodiment 3: Based on Embodiment 2, Figure 7 and attached Figure 8 , also includes a fixing plate 16, the fixing plate 16 is fixedly connected to the top rear side of the working panel 2, the slide plate 5 is horizontally slidably connected to a positioning frame 17 symmetrically distributed along the front and back of the slide plate 5, a second spring 18 is fixedly connected between the positioning frame 17 and the slide plate 5, and the right side of the pressure frame 12 is fixedly connected to a clamping plate 19 symmetrically distributed along the front and back of the slide plate 5, the clamping plate 19 has a serrated groove, and the clamping plate 19 is engaged with the adjacent positioning frame 17 through the serrated groove, so as to fix the positioning frame 17.

[0048] The front and rear corners of the left and right sides of the corrugated cardboard 101 may not be right angles, that is, the left and right sides of the corrugated cardboard 101 are beveled edges. The beveled edge on the left side can be trimmed by the cutting knife 102, while the beveled edge on the right side will cause the right side of the corrugated cardboard 101 to not be placed close to the slide plate 5 when the corrugated cardboard 101 is placed, resulting in the slide plate 5 not completely limiting the right side of the corrugated cardboard 101. If this situation is not noticed during operation, the corrugated cardboard 101 will easily shake left and right during the subsequent cutting process, which will eventually affect the cutting of the corrugated paper. To avoid this situation, the specific operations are as follows:

[0049] Initially, the second spring 18 is in a natural state, and the positioning frame 17 protrudes the slide plate 5 to the left, firstly positioning the rear side of the corrugated board 101 horizontally to contact with the fixing plate 16. When the corrugated board 101 is pushed horizontally to the right, the right side of the corrugated board 101 will directly contact with the positioning frame 17. If the front and rear corners of the right side are both right angles, that is, the right side of the corrugated board 101 is a right angle, then the positioning frames 17 on both sides slide to the right at the same time, and the second spring 18 is compressed at the same time.

[0050] If the front and rear legs of the right side are not at right angles, that is, the right side of the corrugated board 101 is a bevel, the positioning frame 17 that contacts the corrugated board 101 first slides to the right first, and the positioning frame 17 that contacts the corrugated board later slides to the right later, and the second spring 18 deforms to a corresponding degree according to the distance moved by each positioning frame 17, so that the right side of the corrugated board 101 can be completely confined by the positioning frame 17;

[0051] After the corrugated cardboard 101 is adjacent to the two positioning frames 17, do not release the corrugated cardboard 101 yet, and continue to push the working panel 2 backward so that the pressing frame 12 presses the corrugated cardboard 101 downward. At the same time, the pressing frame 12 drives the clamping plate 19 to move downward to clamp the positioning frame 17, thereby fixing the positioning frame 17 to prevent the positioning frame 17 from sliding at will. After fixing, release the corrugated cardboard 101 and start the cutting operation. After the cutting of the corrugated cardboard 101 is completed, the second spring 18 is reset to drive the positioning frame 17 to slide to the left and reset.

[0052] Embodiment 4: Based on Embodiment 3, Fig. 9 , and also includes a push frame 20 for pushing the corrugated paper strip forward. The push frame 20 is slidably connected to the left rear part of the working panel 2 along the front and rear directions. The right front part of the push frame 20 is provided with an inclined surface for scooping up the corrugated paper strip. The push frame 20 is squeezed and matched with the clamping frame 6, and a second tension spring 21 is fixedly connected between the push frame 20 and the working panel 2.

[0053] When the number of cut corrugated paper strips is so large that the clamping frame 6 cannot continue to move to the left, that is, the first spring 7 is compressed to the limit, the clamping frame 6 no longer squeezes the push frame 20, and the second tension spring 21 in the stretched state resets to drive the push frame 20 to slide forward, thereby pushing a cut corrugated paper strip forward, and the inclined surface of the push frame 20 causes the rear end of the pushed corrugated paper strip to be pushed upward, and the inclined corrugated paper strip is easier for people to take out. After taking it out, the first spring 7 resets to drive the clamping frame 6 to move to the right, the clamping frame 6 squeezes the push frame 20 to slide backward, and the second spring 18 returns to the stretched state, and each time a new corrugated paper strip is cut subsequently, the push frame 20 will repeat the above operation to push a corrugated paper strip forward, and people will take away the corrugated paper strip that has been pushed forward until all the corrugated cardboard 101 strips are cut.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
