Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box cross-cutting machines, specifically, to a multi-functional cross-cutting machine for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard boxes are made from corrugated cardboard and are the most widely used paper container packaging, primarily for transport packaging. Corrugated cardboard boxes are characterized by good cushioning performance, lightweight yet sturdy construction, small size, abundant raw materials, low cost, and ease of automated production. They are made by splicing or folding corrugated paper. During production, corrugated cardboard boxes require processing using a cross-cutting machine. The corrugated cardboard cross-cutting machine is a core piece of equipment in the cardboard box processing industry. It uses an electric drive to precisely cut the corrugated cardboard, employing a spring-loaded telescopic rod to drive the lower pressure plate to fix the corrugated paper, combined with an anti-slip textured design to ensure cutting accuracy. Its core components include a grooved slide rail structure and a scale positioning system, enabling precise cutting even at high-speed production speeds of up to 180m / min.

[0003] Cross-cutting machines have special blades that cut corrugated paper through reciprocating rotation. During the production process, paper scraps adhere to the outer edges of the corrugated board, increasing its thickness in some areas and causing uneven thickness. This uneven thickness leads to uneven cutting by the cross-cutting machine, making some sections difficult to cut. Furthermore, the uneven thickness causes significant wear on the blades, affecting the cutting results. Additionally, existing cross-cutting machines are limited in function and cannot trim the edges of the corrugated board. Therefore, pre-trimming the edges is necessary, extending processing time and reducing efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a multi-functional cross-cutting machine for corrugated cardboard box production, which solves the technical problems of existing cross-cutting machines having only one function, being unable to clean the debris on the top of the corrugated cardboard, resulting in uneven cutting of the corrugated cardboard, uneven wear of the blades of the cross-cutting machine, and being unable to pre-trim the edges of the corrugated cardboard.

[0005] According to one aspect, at least one embodiment of the present invention provides a multi-functional cross-cutting machine for corrugated carton production, including a mounting frame, a cross-cutting machine body fixedly connected to the top of the mounting frame, a conveyor frame fixedly connected to the outer end of the cross-cutting machine body, the conveyor frame corresponding to the feed inlet position of the cross-cutting machine body, and a cleaning component provided at the top of the conveyor frame.

[0006] The cleaning assembly includes a cavity cleaning rod fixedly connected inside the conveyor frame. A reciprocating screw is rotatably connected inside the cavity cleaning rod. A cleaning plate is threadedly connected to the outer end of the reciprocating screw. Brush bristles are fixedly connected to the bottom end of the cleaning plate.

[0007] A cutting blade is symmetrically fixedly connected to the top of one side of the conveyor frame, and the inner side of the cutting blade has an arc-shaped structure.

[0008] For example, the conveyor frame is internally rotatably connected to a drive rod, and the drive rod is provided in a plurality of equidistant arrangement, with a drive belt sleeved on the outer end of the plurality of drive rods.

[0009] For example, the cleaning assembly also includes a connecting shell fixedly connected to one side of the conveyor frame. A drive gear is symmetrically rotatably connected inside the connecting shell. Two drive gears mesh with each other. A driven gear meshes with the outer end of the drive gear. The driven gear is rotatably connected inside the connecting shell.

[0010] For example, the radius of the drive spur gear is larger than the radius of the driven spur gear, and the driven spur gear is fixedly connected to the reciprocating lead screw.

[0011] For example, the cleaning assembly also includes a servo motor fixedly connected to the outer end of the connecting housing, and the output end of the servo motor is fixedly connected to one of the transmission gears.

[0012] For example, a feed plate is fixedly connected to the top of the conveyor frame, the feed plate is located at the outer end of the cutting blade, and a guide roller is rotatably connected inside the feed plate.

[0013] For example, the guide rollers are provided in four rectangular arrangement, and side plates are symmetrically fixedly connected to both sides of the conveyor frame.

[0014] For example, a clamping plate is fixedly connected to the inner side of the side plate. The clamping plate is V-shaped, and a limiting roller is rotatably connected between the two clamping plates. The limiting roller is located above the drive belt.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] In this invention, a reciprocating screw drives a cleaning plate threaded to its outer end to reciprocate within a hollow cleaning rod. During this process, the bristles at the bottom clean away paper scraps and pieces from the top of the corrugated cardboard, preventing uneven thickness and ensuring even cutting. This also prevents uneven wear on the blades of the cross-cutting machine, which would otherwise affect the cutting effect. Before cutting, a cutting blade trims the edges of the corrugated cardboard. This cross-cutting machine not only cleans the cardboard but also trims its edges, increasing its functionality and improving production efficiency. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0024] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0025] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0027] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-4 As shown, it illustrates a multi-functional cross-cutting machine for corrugated cardboard box production in one embodiment of the present invention, including a mounting frame 1, a cross-cutting machine body 2 fixedly connected to the top of the mounting frame 1, a conveyor frame 3 fixedly connected to the outer end of the cross-cutting machine body 2, the conveyor frame 3 corresponding to the feed port position of the cross-cutting machine body 2, and a cleaning component 6 provided at the top of the conveyor frame 3.

[0030] The cleaning assembly 6 includes a cavity cleaning rod 601 fixedly connected inside the conveyor frame 3. A reciprocating screw 602 is rotatably connected inside the cavity cleaning rod 601. A cleaning plate 603 is threadedly connected to the outer end of the reciprocating screw 602. A brush bristle 604 is fixedly connected to the bottom end of the cleaning plate 603.

[0031] A cutting blade 7 is symmetrically fixedly connected to the top of one side of the conveyor frame 3, and the inner side of the cutting blade 7 has an arc-shaped structure.

[0032] In some examples, before the corrugated cardboard is cut, the reciprocating screw 602 drives the cleaning plate 603 to move back and forth inside the cavity cleaning rod 601. During the movement, the bristles 604 at the bottom of the cleaning plate 603 clean the paper scraps and pieces on the top of the corrugated cardboard. The cleaned paper scraps and pieces fall to the outer end of the conveyor frame 3, cleaning the paper scraps and pieces on the top of the corrugated cardboard to prevent uneven thickness of the corrugated cardboard. This avoids the cross-cutting machine body 2 from being unable to cut parts of the corrugated cardboard due to uneven thickness. At the same time, it cleans the paper scraps and pieces on the outer end of the corrugated cardboard, reducing the cutting speed of the cross-cutting machine body 2. The wear on the blades is controlled to ensure uniform wear across all blade positions, preventing uneven cutting of the corrugated cardboard due to varying degrees of wear. Before cutting the corrugated cardboard, the two cutting blades 7 at the top of the conveyor frame 3 trim the edges of the corrugated cardboard, ensuring both sides are flush. This pre-trimming process shortens the processing time and improves production efficiency. This device not only cleans the corrugated cardboard but also trims its edges, enhancing the functionality of the cross-cutting machine body 2.

[0033] For example, such as Figure 1 As shown, the inside of the conveyor frame 3 is rotatably connected to a drive rod 4. The drive rod 4 is provided in several and is arranged at equal intervals. The outer ends of the drive rod 4 are fitted with drive belts 5.

[0034] In some examples, during the transportation of corrugated cardboard, several rotating drive rods 4 drive the outer drive belt 5 to rotate. Through the friction between the corrugated cardboard and the drive belt 5, the corrugated cardboard moves into the interior of the cross-cutting machine body 2, completing the feeding operation.

[0035] For example, such as Figure 3 As shown, the cleaning component 6 also includes a connecting shell 605 fixedly connected to one side of the conveyor frame 3. A transmission spur gear 606 is symmetrically rotatably connected inside the connecting shell 605. The two transmission spur gears 606 mesh with each other. A driven spur gear 607 meshes with the outer end of the transmission spur gear 606. The driven spur gear 607 is rotatably connected inside the connecting shell 605.

[0036] In some examples, during the cleaning of paper scraps and pieces from the outer end of corrugated cardboard, one drive gear 606 drives another drive gear 606 to rotate inside the connecting housing 605. At the same time, the two drive gears 606 drive the driven gear 607 meshing with their outer ends to rotate. The rotating driven gear 607 drives the reciprocating screw 602 fixed at its outer end to rotate inside the cavity cleaning rod 601, thereby causing the cleaning plate 603 to reciprocate inside the cavity cleaning rod 601.

[0037] For example, such as Figure 3 As shown, the radius of the transmission spur gear 606 is larger than the radius of the driven spur gear 607, and the driven spur gear 607 is fixedly connected to the reciprocating lead screw 602.

[0038] In some examples, since the radius of the drive spur gear 606 is larger than the radius of the driven spur gear 607, the driven spur gear 607 rotates rapidly, thereby increasing the moving speed of the cleaning plate 603 inside the cavity cleaning rod 601 and improving the cleaning effect of its bottom bristles 604 on the outer end of the corrugated cardboard. At the same time, the cavity cleaning rod 601 is provided in two sets, which can clean the corrugated cardboard from both sides at the same time.

[0039] For example, such as Figure 1 As shown, the cleaning component 6 also includes a servo motor 608 fixedly connected to the outer end of the connecting housing 605, and the output end of the servo motor 608 is fixedly connected to one of the transmission spur gears 606.

[0040] In some examples, a servo motor 608 is configured to drive one of the drive spur gears 606 to rotate, thereby causing the spur gear to drive another drive spur gear 606 and two driven spur gears 607 to rotate.

[0041] like Figure 1 and Figure 4 As shown, it illustrates a multi-functional cross-cutting machine for corrugated cardboard box production in another embodiment of the present invention. The top of the conveyor frame 3 is fixedly connected to a feed plate 8, which is located at the outer end of the cutter 7. A guide roller 9 is rotatably connected inside the feed plate 8.

[0042] In some examples, during the trimming process of corrugated cardboard, the pressure is applied to make the two sides of the corrugated cardboard come into contact with the cutting blade 7. At the same time, the inner curved cutting blade 7 causes the cut waste to slide out from both sides of the conveyor frame 3, which facilitates fast material discharge and prevents the cut waste from falling on the top of the corrugated cardboard, thus affecting the cutting effect of the corrugated cardboard.

[0043] For example, such as Figure 1 and Figure 4As shown, there are four guide rollers 9 arranged in a rectangular shape, and side plates 10 are symmetrically fixedly connected to both sides of the conveyor frame 3.

[0044] In some examples, during the feeding process, one end of the corrugated cardboard passes through the inside of the feed plate 8 and moves to the top of the drive belt 5. Four sets of rectangular guide rollers 9 are set to enhance the stability of the corrugated cardboard during transportation.

[0045] For example, such as Figure 1 and Figure 4 As shown, a clamping plate 11 is fixedly connected to the inner side of the side plate 10. The clamping plate 11 is V-shaped, and a limiting roller 12 is rotatably connected between the two clamping plates 11. The limiting roller 12 is located above the drive belt 5.

[0046] In some examples, during the feeding process, the limiting rollers 12 between the two sets of V-shaped clamps 11 limit the drive belt 5 from the top to prevent the squeezing force between the cutter 7 and the corrugated cardboard from causing the corrugated cardboard to warp, so that the corrugated cardboard can accurately enter the interior of the cross-cutting machine body 2 for processing.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
