Description

Technical Field

[0001] The invention relates to a corrugated paper box board cutting machine with an automatic pressing mechanism. Background Art

[0002] Corrugated boxes are rigid paper containers made of corrugated cardboard. They are the most widely used packaging products. They are used in almost all fields. In the production of corrugated boxes, punching is an essential operation. When processing corrugated boxes, it is necessary to cut the edges of the corrugated boxes, increase the gaps at the corners of the corrugated boxes, and increase the air circulation of the corrugated boxes.

[0003] In a Chinese patent with publication number CN214324324U, a corrugated cardboard rapid prototyping cutting machine is disclosed. A workbench is installed on a base, and a limiting groove is installed in the workbench. The cardboard cut to size falls onto a slideway and comes to the base through the slideway. The constructor puts the cut cardboard on the workbench, and a limiting groove is installed in the workbench. The cardboard is fixed by the limiting groove. The pressing plate is driven down by the descent of the cylinder. The blade template on the pressing plate compresses and cuts the cardboard through a rubber sleeve. The limiting groove can prevent the compressed cardboard from deflecting, so that the cut and compressed corrugated cardboard is more compact. A reserved groove is provided in the cutting table. A paper trough is installed inside, and the paper trough is set to a pull-out structure. When the size cutting is performed on the cutting board, the waste paper generated will fall into the paper trough. When the paper trough is full, the paper trough filled with paper scraps can be pulled out by the handle for cleaning, thereby avoiding the situation where paper scraps cannot be cleaned during the cutting process, and effectively improving the environmental protection of the device; by installing a slider at the bottom of the cutting board, the slider is installed in the slide groove of the cutting table, so that the slider can drive the upper cutting board to move. When the cardboard to be cut is placed on the cutting board, the position between the cutting board and the cutter can be adjusted to cut cardboards of different sizes, making the cutting of the cardboard more flexible, and effectively improving the cutting range of the device.

[0004] At present, the corrugated box board rapid prototyping and cutting machine disclosed in the above patent has certain technical deficiencies:

[0005] 1. When processing corrugated boxes, if the corrugated boxes are not pressed, the corrugated boxes will have a certain deviation, affecting the cutting effect;

[0006] 2. During the cutting process, the contact between the blade and the knife groove can easily cause the blade to wear more severely and shorten the service life of the blade. Summary of the invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art.

[0008] The present application provides a corrugated cardboard cutting machine with an automatic pressing mechanism, including:

[0063] Next, in conjunction with the accompanying drawings, the server provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0064] Embodiment 1:

[0065] As Figures 1 to 3As shown in the figure, an embodiment of the present application provides a corrugated cardboard cutting machine with an automatic pressing mechanism, which includes a frame 1, on the top of which a housing 2 is installed; a conveyor belt 3, which is installed on the frame 1 and includes a driving roller 301 driven by a motor and a driven roller 303 that rotates together with the driving roller 301 through a conveyor belt 302; a bearing table 4, which has a bearing groove 5 and is installed on the frame 1 and can be lifted between the frame 1 and the housing 2; a cutting mechanism 6, which has a pair and is symmetrically installed on both sides of the top of the housing 2; a conveying mechanism 7, which is used to convey the corrugated cardboard to be cut at one end of the conveyor belt 3 to the bearing table 4 or convey the cut corrugated cardboard from the bearing table 4 to the other end of the conveyor belt 3; a clamping mechanism, which includes two pressing units 8 respectively installed on opposite sides of the bearing table 4 for clamping both ends of the corrugated cardboard when the bearing table 4 rises.

[0066] In the embodiment of the present application, the above-mentioned corrugated cardboard cutting machine with an automatic pressing mechanism is adopted. The worker places the corrugated cardboard to be cut at one end of the conveyor belt 302. The motor drives the driving roller 301 to rotate, and the conveyor belt 302 rotates between the driving roller 301 and the driven roller 303 to convey the corrugated cardboard to be cut near the bearing table 4. The conveying mechanism 7 conveys the corrugated cardboard to be cut into the bearing groove 5. Subsequently, the bearing table 4 rises. During the rising process of the bearing table 4, the two pressing units 8 of the clamping mechanism respectively press and fix both ends of the corrugated cardboard. The bearing table 4 continues to rise, and the corrugated cardboard to be cut enters the cutting range of the cutting mechanism 6. The cutting mechanism 6 cuts the corrugated cardboard. After the cutting is completed, the bearing table 4 descends, and the clamping mechanism releases the fixation of the corrugated cardboard. The conveying mechanism 7 moves the cut corrugated cardboard to the other end of the conveyor belt 302. The conveyor belt 302 conveys the cut corrugated cardboard out of the frame 1. Through the setting of the clamping mechanism, the corrugated cardboard will not shift when being cut by the cutting mechanism 6, improving the cutting effect.

[0067] Embodiment 2:

[0068] In this embodiment, in addition to including the structural features of the foregoing embodiment, the pressing unit 8 includes a pressing groove 801, which is arranged at the bottom of the side wall of the bearing groove 5; a pressing plate 802, which is vertically slidably installed in the pressing groove 801; a lifting rod 803, the bottom end of which is fixedly connected to the top surface of the pressing plate 802, and the top end of which movably penetrates through the bearing table 4 and extends above the bearing table 4; a bearing plate 804, which is fixedly installed at the top end of the lifting rod 803; a first return spring 805, which is sleeved outside the lifting rod 803 and the two ends of which respectively abut against the top of the bearing table 4 and the bottom of the bearing plate 804; a pressing frame 9, which is installed on the top of the inner side wall of the housing 2.

[0069] In this embodiment, due to the adoption of the above structure, when the carrier table 4 rises to the upper part of the inner cavity of the casing 2, the bottom end of the pressing frame 9 contacts the bearing plate 804. As the carrier table 4 continues to rise, the bearing plate 804 moves relative to the carrier table 4 under the action of the pressing frame 9, and the pressing plate 802 moves downward in the pressing groove 801 driven by the lifting rod 803. When the corrugated cardboard to be cut in the carrier groove 5 moves into the working range of the cutting mechanism 6, the bottom surface of the pressing plate 802 abuts against the corrugated cardboard to be cut, pressing the corrugated cardboard to be cut against the bottom of the pressing groove 801 to prevent the corrugated cardboard from shifting during cutting. After cutting is completed, the carrier table 4 descends. Under the action of the first reset spring 805, the bearing plate 804, the lifting rod 803, and the pressing plate 802 move upward, and the pressing plate 802 disengages from the contact with the corrugated cardboard, releasing the fixation of the corrugated cardboard. When the carrier table 4 descends, the cut corrugated cardboard is moved to the other end of the conveyor belt 302 by the conveying mechanism 7. In this way, the pressing unit 8 operates together with the lifting and lowering of the carrier table 4. The structure is simple, without the need for other motors or other active mechanisms to control it, reducing production costs, control difficulty, failure rate, and operation and maintenance costs, and improving work efficiency.

[0070] Embodiment 3:

[0071] In this embodiment, in addition to including the structural features of the foregoing embodiment, the pressing frame 9 includes a first lifting groove 901 provided at the top of the inner side wall of the casing 2; a frame body 902 having an L shape and vertically slidably installed in the first lifting groove 901; and a buffer spring 903 installed between the top end of the frame 1 and the top end of the first lifting groove 901.

[0072] In this embodiment, due to the adoption of the above structure, when the carrier 4 rises, when the elastic force of the buffer spring 903 is less than the elastic force of the first reset spring 805, the bottom of the frame body 902 first contacts the bottom surface of the bearing plate 804. As the carrier 4 rises, the frame body 902 rises in the first lifting groove 901, causing the buffer spring 903 to be compressed and shortened. Until the buffer spring 903 is compressed to the limit, the carrier 4 still continues to rise. When the corrugated cardboard to be cut in the carrier groove 5 moves to the working range of the cutting mechanism 6, the bottom surface of the pressing plate 802 abuts against the corrugated cardboard to be cut, pressing the corrugated cardboard to be cut against the bottom of the pressing groove 801. Through the settings of the buffer spring 903 and the first lifting groove 901, the impact force generated when the bottom of the frame body 902 contacts the bearing plate 804 is absorbed, improving the service life of the frame body 902. When the elastic force of the buffer spring 903 is greater than the first reset spring 805, as the carrier 4 continues to rise, the bearing plate 804 contacts the frame body 902, and the first to deform is the first reset spring 805. The bearing plate 804 drives the pressing plate 802 to descend in the pressing groove 801 through the lifting rod 803. After the bearing plate 804 presses the corrugated cardboard in the pressing groove 801, as the carrier 4 rises, the buffer spring 903 is shortened again. In this way, the time for the corrugated cardboard to be fixed is extended, preventing the corrugated cardboard from shifting in the carrier groove 5 during the rising process of the carrier 4 and improving the fixing effect on the corrugated cardboard.

[0073] Embodiment 4:

[0074] In this embodiment, in addition to including the structural features of the foregoing embodiment, the conveying mechanism 7 includes guiding rollers 701, and there are a pair of them, which are respectively rotatably installed at both ends of the top of the frame 1; conveying rollers 702, and there are several pairs of them, which are installed on the top of the carrier 4; through grooves 703, and there are several of them, which are arranged at intervals at the bottom of the carrier 4 and communicate with the carrier groove 5 for the top ends of the conveying rollers 702 to extend into the carrier groove 5; wherein, the bottom surface of the upper side of the conveyor belt 302 abuts against the outer wall of the guiding roller 701, and the top surface abuts against the outer wall of the conveying roller 702.

[0075] In this embodiment, due to the adoption of the above structure, with the arrangement of the guide roller 701, the upper top surface of the conveyor belt 302 abuts against the outer wall of the conveying roller 702. As the conveyor belt 302 runs, it drives each conveying roller 702 to rotate. Through the arrangement of the through groove 703, the conveying roller 702 can convey the corrugated cardboard box to the bearing groove 5. When the bearing table 4 rises, the bearing groove 5 moves away from the conveying roller 702, and the conveying roller 702 can no longer drive the corrugated cardboard box to move. When the bearing table 4 carrying the cut corrugated cardboard box descends to the lowest point, the conveying roller 702 extends into the bearing groove 5 through the through groove 703, conveys the cut corrugated cardboard box onto the conveyor belt 302, and conveys the cut corrugated cardboard box outside the frame 1 through the conveyor belt 302. The above structure is simple. With the lifting of the bearing table 4, the conveying process of the corrugated cardboard box is completed. The structure is simple, without the need for other motors or other active mechanisms to control it, reducing the production cost, control difficulty, failure rate and operation and maintenance cost, and improving the work efficiency.

[0076] Embodiment 5:

[0077] In this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes a plurality of second lifting grooves 11, which are respectively installed on the opposite inner side walls of the machine shell 2; a plurality of lifting sliders 12, which are respectively vertically and slidably installed in each of the second lifting grooves 11; a lifting device 13, which is used to drive the lifting sliders 12 to lift and lower in the second lifting grooves 11; wherein, the side wall of the bearing table 4 is fixedly connected to each of the lifting sliders 12.

[0078] In this embodiment, due to the adoption of the above structure, the lifting device 13 can be selected from one of a cylinder, an oil cylinder, an electric cylinder or a linear motor to drive each of the lifting sliders 12 to lift and lower in each of the second lifting grooves 11. Through the cooperation of each of the lifting sliders 12 and each of the second lifting grooves 11, the stability of the bearing table 4 during lifting is improved.

[0079] Embodiment 6:

[0080] In this embodiment, in addition to including the structural features of the foregoing embodiment, the cutting mechanism 6 includes a cutter, which includes a blade body 601 and a blade edge 602; an avoidance groove 603, which is arranged at the bottom of the bearing table 4 and has a depth greater than the length of the blade edge 602; wherein, the blade edge 602 is composed of a plurality of cutting units connected end to end in a V shape.

[0081] In this embodiment, due to the adoption of the above structure, as the carrier table 4 rises, after the pressing unit 8 fixes both ends of the corrugated cardboard to be cut, the bottom end of the cutting edge 602 of the cutter penetrates into the corrugated cardboard. As the carrier table 4 continues to rise, the cutting edge 602 gradually penetrates into the avoidance groove 603 until both ends of the corrugated cardboard are cut off. Through the arrangement of multiple V-shaped cutting units, the cutting edge 602 can easily cut into the corrugated cardboard. The pressing unit 8 presses the corrugated cardboard to prevent the corrugated cardboard from being pushed into the avoidance groove 603 by the cutting edge 602. By making the depth of the avoidance groove 603 greater than the length of the cutting edge 602, contact between the cutting edge 602 and the avoidance groove 603 is avoided. In this way, the service life of the cutter is improved.

[0082] Embodiment 7:

[0083] In this embodiment, in addition to including the structural features of the foregoing embodiment, the cutting mechanism 6 further includes a linkage column 604, the bottom end of which is fixedly connected to the top of the tool body 601, and the top end of which movably penetrates through the top end of the machine housing 2 and extends above the machine housing 2; a linkage plate 605, which is fixedly installed at the top end of the linkage column 604; and a linkage mechanism 10, which is used to lower the linkage plate 605 when the frame 902 rises.

[0084] In this embodiment, due to the adoption of the above structure, when the frame 902 rises, the linkage mechanism 10 drives the linkage plate to descend, causing the tool body 601 to descend in the inner cavity of the machine housing 2 and move relative to the rising carrier table 4. While shortening the rising stroke of the carrier table 4, the cutter receives a two-way force, and the cutting edge 602 can more easily cut into the corrugated cardboard, avoiding the phenomenon that the corrugated cardboard is deformed and falls into the avoidance groove 603 due to the excessive thickness or high strength of the corrugated cardboard and insufficient impact force when the carrier table 4 rises, resulting in the cutter being unable to cut the corrugated cardboard. The working efficiency and the cutting effect are improved.

[0085] Embodiment 8:

[0086] In this embodiment, in addition to including the structural features of the foregoing embodiment, the linkage mechanism 10 includes a rotating shaft 1001, which is rotatably installed on the top of the machine housing 2 through a bearing seat; a pair of cams 1002, which are fixedly installed at both ends of the rotating shaft 1001; a linkage frame 1003, the bottom end of which is fixedly connected to the top of one of the frames 902, and the top end of which movably penetrates through the top of the machine housing 2 and extends above the machine housing 2; a linkage groove 1004, which is installed at the top end of the linkage frame 1003 and extends horizontally; and a linkage block 1005, one end of which is fixedly installed at an eccentric position on the outer side wall of one of the cams 1002 and is slidably connected to the linkage groove 1004. Among them, the circumferential surfaces of the cams 1002 are respectively in contact with the top surfaces of the linkage plates 605.

[0087] In this embodiment, due to the adoption of the above structure, when the frame 902 rises, the linkage frame 1003 rises accordingly, causing the linkage block 1005 to slide in the linkage groove 1004, driving one of the cams 1002 to rotate. Through the arrangement of the rotating shaft 1001, the other cam 1002 rotates together. The convex sides of the cams 1002 rotate to contact the top surface of the linkage plate 605. As the frame 902 continues to rise until the carrier table 4 rises to the highest point, the highest point of the convex side of the cam 1002 abuts against the top surface of the linkage plate 605, causing the cutter to descend to the lowest point, completing the cutting of the corrugated cardboard. The above structure is simple and does not require other motors or other active mechanisms to control it, reducing production costs, control difficulty, failure rate, and operation and maintenance costs, and improving work efficiency.

[0088] Embodiment 9:

[0089] In this embodiment, in addition to including the structural features of the foregoing embodiment, the linkage mechanism 10 further includes a second reset spring 1006, which is sleeved outside the linkage column 604 and its top and bottom are respectively abutted against the bottom of the linkage plate 605 and the top of the machine housing 2.

[0090] In this embodiment, due to the adoption of the above structure, through the arrangement of the second reset spring 1006, the top surface of the linkage plate 605 is always kept in contact with the circumferential surface of the cam 1002. After the convex side of the cam 1002 disengages from the contact with the linkage plate 605, the linkage plate 605 can drive the cutter to rise to the initial position in the machine housing 2 through the linkage column 604, enabling the cutter to automatically reset after cutting the corrugated cardboard and improving the cutting efficiency.

[0091] Embodiment 10:

[0092] In this embodiment, in addition to including the structural features of the foregoing embodiment, the linkage mechanism 10 further includes a reinforcing plate 1007, which is installed between the bottom of the linkage groove 1004 and the outer side wall of the linkage frame 1003.

[0093] In this embodiment, due to the adoption of the above structure, through the arrangement of the reinforcing plate 1007, support is provided for the end of the linkage groove 1004 far from the linkage frame 1003, improving the structural strength of the linkage groove 1004 and extending the service life of the linkage groove 1004.
