Description

Technical Field

[0001] This utility model relates to the technical field of creasing and cutting devices, specifically a multi-functional combined cutting and creasing trolley. Background Technology

[0002] In many fields such as printing and packaging, office printing, and paper processing, cutting, dotted line cutting, and creasing are core basic processes in the post-processing of paper products, which directly affect the forming quality, usage effect, and production efficiency of paper products.

[0003] Currently, most cutting and creasing carts on the market adopt a single-function design or a modular design that requires frequent blade changes. The two core forming processes, cutting and creasing, are generally independent, forming a typical "step-by-step operation with manual intervention" model. Specifically, the processing flow usually begins with the cardboard cutting stage: the worker first places the entire roll or sheet of raw cardboard flat on the feeding table of a dedicated cutting machine, adjusts the spacing and stroke of the cutting blades according to the preset carton size parameters, and then starts the machine to precisely cut the cardboard to obtain cardboard blanks that meet the specifications. After cutting, due to a lack of... The automated connection between processes requires manual transfer of cut cardboard blanks to another cardboard creasing machine in batches using forklifts, handcarts, or direct handling. During the transfer, to avoid deformation or surface wear caused by stacking and squeezing the cardboard, the amount of material handled at one time must be controlled and protective measures must be taken. After all the cardboard blanks have been transferred to the feeding end of the creasing machine, the operator feeds them into the creasing machine batch by batch, adjusting the position and pressure of the creasing rollers according to the crease requirements of the carton to complete the creasing process. This not only increases the equipment purchase cost and the space occupied, but also requires frequent transfer of paper products, extending the overall processing cycle.

[0004] Patent application CN222712954U discloses an automatic cardboard cutting and creasing device. The device features an adjustment mechanism at the top of the base, and a cutting and creasing assembly inside the base, with cardboard held in place within the assembly. This invention effectively adjusts the position of the limiting frame and its inner cutter using the adjustment mechanism, facilitating the determination of the cutter's landing point. Then, an electric push rod effectively drives the clamp and pressure plate to adjust their positions, thereby determining the pressing point. The downward movement of the adjustment mechanism causes the cutter and pressure plate to move downwards simultaneously, enabling simultaneous cutting and creasing of the cardboard.

[0005] However, this patent has the following drawbacks: the cutting and creasing equipment cannot be used in combination according to the actual cutting and creasing work; it is difficult to adapt to diverse working scenarios, which limits its application flexibility under complex processing requirements. Utility Model Content

[0006] To address the problems in existing technologies where cutting and creasing carriages are mostly single-function or require frequent tool changes, which not only increase equipment purchase costs and space occupation, but also prolong the overall processing cycle due to frequent manual transfer, and lack reasonable tool layout and height difference design, where tools corresponding to different functions are installed on the same actuator, and idle tools are prone to contact with the paper surface and cause scratches when switching functions, thus requiring the removal of temporary tools and installation of the required tools, and frequent loading and unloading can lead to a decrease in tool installation accuracy and affect processing quality, this utility model provides a multi-functional combined cutting and creasing carriage.

[0007] The objective of this utility model can be achieved through the following technical solutions: A multifunctional combined cutting and creasing carriage includes a main frame, which is composed of a vertical and two horizontal I-beams. A right feed guide rod is fixedly connected to one side of the upper surface of the main frame, and a left feed guide rod is fixedly connected to the other side. A middle feed guide rod is fixedly connected to the end of the main frame away from the horizontal cutting module. A right blade holder is fixedly connected to the upper surface of the right feed guide rod, and a left blade holder is fixedly connected to the upper surface of the left feed guide rod. A middle blade holder is fixedly connected to the upper surface of the middle feed guide rod. A right blade clamp is fixedly connected to the lower end of the right blade holder, and a right cutting blade is connected to the lower end of the right blade clamp. A left blade clamp is fixedly connected to the lower end of the left blade holder, and a left cutting blade is connected to the lower end of the left blade clamp. A middle blade clamp is fixedly connected to the lower end of the middle blade holder, and a middle cutting blade is connected to the lower end of the middle blade clamp.

[0008] Furthermore, a synchronous pulley is rotatably connected to the upper surface of the transverse I-beam plate at the lower part of the main frame. The synchronous pulleys are distributed in a triangular pattern, and a synchronous toothed belt is engaged on the outer side of each synchronous pulley. A tensioning pulley is provided on the outer side of the synchronous toothed belt, and the tensioning pulley is located between adjacent synchronous pulleys.

[0009] Furthermore, the center feed guide rod is located between the left feed guide rod and the right feed guide rod, and a center tool post is provided between the right tool post and the left tool post.

[0010] Furthermore, a right voice coil motor is provided on the lower surface of the upper crossbar of the right tool holder. A first linear bearing is provided on the side of the right voice coil motor near the right tool holder, and a right guide linear bearing is provided on the side of the right voice coil motor away from the right tool holder. One end of a spring is fixedly connected to the lower surface of both the first linear bearing and the right guide linear bearing, and the other end of the spring is fixedly connected to the upper surface of the transverse I-beam plate on the upper part of the main frame.

[0011] Furthermore, a left voice coil motor is provided on the lower surface of the upper crossbar of the left tool holder. A second linear bearing is provided on the side of the left voice coil motor near the left tool holder, and a left guide linear bearing is provided on the side of the left voice coil motor away from the left tool holder. Springs are fixedly connected to the lower surfaces of both the second linear bearing and the left guide linear bearing.

[0012] Furthermore, a mid-range coil motor is installed on the lower surface of the upper crossbar of the middle tool holder, and a middle guide linear bearing is installed on both sides of the middle tool holder. A spring is fixedly installed between the middle guide linear bearing and the main frame.

[0013] Furthermore, a first rotary blade bearing is provided on the side of the right blade holder near the transverse cutting module. A first rotary blade rod is mounted on the first rotary blade bearing. The first rotary blade rod passes through the synchronous pulley and connects to the first blade holder. A right rotary blade is connected to the bottom of the first blade holder.

[0014] Furthermore, a second rotary blade bearing is provided on the side of the left blade holder near the transverse cutting module. A second rotary blade rod is mounted on the second rotary blade bearing. The second rotary blade rod passes through the synchronous belt pulley and connects to the second blade holder. A left rotary blade is connected to the bottom of the second blade holder.

[0015] Furthermore, the working height of the right cutting blade, the middle cutting blade, and the left cutting blade is greater than the idle height of the left and right rotary blades.

[0016] The beneficial effects of this utility model are: 1. This utility model integrates three basic functions—cutting, dotted line cutting, and creasing—through the set height difference and modular loading and unloading design, and can more flexibly combine double-line equidistant cutting / creasing modes; it breaks the limitations of the single function of traditional equipment or the cumbersome tool replacement, and integrates five tools—left / right cutting blade, left / right rotating blade, and middle drag blade—into one.

[0017] 2. This utility model, by setting the "working height of the cutting blade to be greater than the idle height of the rotating blade", ensures that the idle rotating blade will not contact the paper when using the cutting blade mode. The working mode can be quickly and seamlessly switched without disassembling the temporary blade, greatly improving the efficiency and convenience of operation. At the same time, the left / right cutting blades, left / right rotating blades and middle cutting blade are independent of each other and can be freely combined and used in a "building block" manner according to production needs (such as using the middle drag blade alone, or combining the left and right blades to achieve dual-line operation), giving production a high degree of flexibility.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 As shown, a multi-functional combined cutting and creasing carriage includes a main frame 15, an outer shell 1 on the outside of the main frame 15, a transverse cutting module 2 fixedly connected to the upper surface of one end of the main frame 15, a controller 6 on the transverse cutting module 2, the controller 6 controls the transverse cutting module 2 to slide, and controls the drive mechanism through the controller 6 to move the transverse cutting module 2, the movement of the transverse cutting module 2 drives the entire creasing carriage to move to perform cutting or creasing work.

[0022] Please see Figure 6 As shown, the main frame 15 is composed of three I-beams. One I-beam is set vertically. On the side of the vertically set I-beam away from the horizontal cutting module 2, a horizontal I-beam is fixedly connected to the upper and lower parts. The two horizontal I-beams and the vertical I-beam form a U-shaped structure with the opening facing away from the horizontal cutting module 2.

[0023] Please see Figure 2-3 As shown, a right feed guide rod 11 is fixedly connected to one side of the horizontally arranged I-beam plate, and the right feed guide rods 11 are symmetrically arranged; a left feed guide rod 12 is fixedly connected to the other side of the horizontally arranged I-beam plate, and the left feed guide rods 12 are symmetrically arranged; a middle feed guide rod 13 is fixedly connected to the end of the horizontally arranged I-beam plate away from the horizontal cutting module 2; the middle feed guide rod 13 is located between the left feed guide rod 12 and the right feed guide rod 11.

[0024] The upper surface of the right feed guide rod 11 is fixedly connected to the right tool holder 31, the upper surface of the left feed guide rod 12 is fixedly connected to the left tool holder 51, and the upper surface of the middle feed guide rod 13 is fixedly connected to the middle tool holder 41.

[0025] Please refer to Figure 3-5. The right blade holder 31 and the left blade holder 51 are both F-shaped, and the middle blade clamp 4 is L-shaped. The lower end of the right blade holder 31 is fixedly connected to the right blade clamp 3, and the lower end of the right blade clamp 3 is connected to the right cutting blade 32. The lower end of the left blade holder 51 is fixedly connected to the left blade clamp 5, and the lower end of the left blade clamp 5 is connected to the left cutting blade 52. The lower end of the middle blade holder 41 is fixedly connected to the middle blade clamp 4, and the lower end of the middle blade clamp 4 is connected to the middle cutting blade 42. The right cutting blade 32, the middle cutting blade 42, and the left cutting blade 52 are arranged side by side and installed at the same height.

[0026] Please refer again to Figure 3-4. The lower surface of the upper crossbar of the right blade holder 31 is provided with a right voice coil motor 8. The right voice coil motor 8 is provided with a first linear bearing 82 on the side near the right blade clamp 3, and a right guide linear bearing 81 is provided on the side of the right voice coil motor 8 away from the right blade clamp 3. The lower surfaces of the first linear bearing 82 and the right guide linear bearing 81 are both fixedly connected to one end of a spring 22. The other end of the spring 22 is fixedly connected to the upper surface of the transverse I-beam plate on the upper part of the main frame 15. The spring 22 is located on the outer wall of the right feed guide rod 11. The spring 22 is used for the reset of the right cutting blade 32.

[0027] By activating the right voice coil motor 8, the electromagnetic force of the right voice coil motor 8 drives the right blade holder 31 downward. The downward movement of the right blade holder 31 causes the right guide linear bearing 81 and the first linear bearing 82 to move downward along the right feed guide rod 11, compressing the spring 22. The downward movement of the right blade holder 31 causes the right cutting blade 32 to move downward, thus achieving the cutting operation. In the non-cutting state, the right voice coil motor 8 is turned off, the spring 22 returns to its original position, and the right cutting blade 32 moves upward. The working principle of the left cutting blade 52 and the middle cutting blade 42 is the same; the left cutting blade 52 and the middle cutting blade 42 can be driven independently.

[0028] By driving the transverse cutting module 2, the transverse cutting module 2 drives the entire main frame 15 to move, thereby driving the trolley to perform the cutting work.

[0029] A left voice coil motor 9 is provided on the lower surface of the upper crossbar of the left tool holder 51. A second linear bearing 92 is provided on the side of the left voice coil motor 9 near the left tool holder 5, and a left guide linear bearing 91 is provided on the side of the left voice coil motor 9 away from the left tool holder 5. One end of a spring 22 is fixedly connected to the lower surface of both the second linear bearing 92 and the left guide linear bearing 91. The other end of the spring 22 is fixedly connected to the upper surface of the transverse I-beam plate on the upper part of the main frame 15. The spring 22 is located on the outer wall of the left feed guide rod 12. The spring 22 is used for the reset of the left indentation tool.

[0030] A middle tool post 41 is provided between the right tool post 31 and the left tool post 51. A middle voice coil motor 10 is provided on the lower surface of the upper crossbar of the middle tool post 41. A middle guide linear bearing 1001 is provided on both sides of the middle tool post 41. A spring 22 is fixedly installed between the middle guide linear bearing 1001 and the main frame 15. The spring 22 is located on the outer wall of the middle feed guide rod 13.

[0031] The left voice coil motor 9, the middle voice coil motor 10, and the right voice coil motor 8 are all located on the upper surface of the transverse I-beam plate on the upper part of the main frame 15.

[0032] Please refer again to Figure 6-8. The upper surface of the transverse I-beam plate at the lower part of the main frame 15 is rotatably connected to a synchronous pulley 18. There are three synchronous pulleys 18, which are arranged in a triangular pattern. The outer side of each synchronous pulley 18 is engaged with a synchronous toothed belt 14. The outer side of the synchronous toothed belt 14 is provided with a tensioning pulley 21, which is located between adjacent synchronous pulleys 18.

[0033] A rotating motor 7 is provided above the synchronous pulley 18 near the side of the transverse cutting module 2. The rotating motor 7 is used to drive the synchronous pulley 18 to rotate.

[0034] The right blade holder 31 is provided with a first rotary blade bearing 1601 on the side near the transverse cutting module 2. A first rotary blade rod 16 is installed on the first rotary blade bearing 1601. The first rotary blade rod 16 passes through the synchronous pulley 18 and is connected to the first blade holder 19. A right rotary blade 1901 is connected to the bottom of the first blade holder 19.

[0035] By starting the rotary cutter motor, the rotary cutter motor drives the synchronous pulley 18 to rotate the cutter. The synchronous pulley 18 drives the synchronous toothed belt 14 to drive the other two synchronous pulleys 18 to rotate the cutter. The rotation of the synchronous pulleys 18 drives the first rotary cutter bar 16 and the second rotary cutter bar 17 to rotate. The first rotary cutter bar 16 and the second rotary cutter bar 17 drive the right rotary cutter 1901 and the left rotary cutter 2001 to rotate, thus realizing the indentation work.

[0036] A second rotary blade bearing 1701 is provided on the side of the left blade holder 51 near the transverse cutting module 2. A second rotary blade rod 17 is installed on the second rotary blade bearing 1701. The second rotary blade rod 17 passes through the synchronous pulley 18 and connects to the second blade holder 20. A left rotary blade 2001 is connected to the bottom of the second blade holder 20.

[0037] The working height of the right cutting blade 32, the middle cutting blade 42, and the left cutting blade 52 is greater than the idle height of the left-turning blade 2001 and the right-turning blade 1901. This ensures that when using the right cutting blade 32, the middle cutting blade 42, and the left cutting blade 52, the idle left-turning blade 2001 and the right-turning blade 1901 will not come into contact with the paper. Therefore, it is not necessary to disassemble the left-turning blade 2001 and the right-turning blade 1901 when they are not in use. This achieves a quick and seamless switching of working modes, which greatly improves the efficiency and convenience of operation.

[0038] The left cutting blade 52, right cutting blade 32 / left-turning blade 2001 and right-turning blade 1901 are independent of each other and can be freely combined and used like "building blocks" according to production needs.

[0039] For example, when the right-hand cutting blade 1901 needs to be used: remove the right cutting blade 32 on the same side. At this time, the blade on that side will rise to the working height and begin the creasing operation.

[0040] When using the right cutting blade 32, the middle cutting blade 42, and the left cutting blade 52: there is no need to remove the left-turning blade 2001 and the right-turning blade 1901. Due to the height difference, the left-turning blade 2001 and the right-turning blade 1901 are automatically in a "avoidance" state and will not interfere with the operation of the right cutting blade 32, the middle cutting blade 42, and the left cutting blade 52.

[0041] The left cutting blade 52 / left-turning blade 2001 and the right cutting blade 32 / right-turning blade 1901 are each a module that can be independently installed, removed and adjusted. They are used to process two equally spaced cutting lines or creasing lines; or the middle cutting blade can be used alone, or the left and right blades can be combined to achieve dual-line operation, providing extremely high production flexibility.

[0042] During a single paper feeding process, one cutting line and two creasing lines of a paper box can be completed simultaneously; or two parallel lines with equal spacing can be cut at the same time; thus achieving the combined processing of solid and dashed lines on a single product.

[0043] Working principle: When it is necessary to cut one cutting line and two creasing lines on paper, first disassemble the left cutting blade 52 and the right cutting blade 32, then raise the left rotating blade 2001 and the right rotating blade 1901 to the working height to start the creasing operation; at the same time, the middle cutting blade 42 begins to rise to the working height to start the cutting operation.

[0044] When it is necessary to cut two parallel lines with equal spacing from the paper, there is no need to disassemble the rotary blade. The working height of the left cutting blade 52 and the right cutting blade 32 is controlled by the voice coil motor to start the cutting work.

[0045] When it is necessary to cut a crease and a cut on paper, the left or right cutting blade 32 can be disassembled to put the other cutting blade into working condition, and then the disassembled blade on the same side can be used to perform the crease work.

[0046] It achieves "one set of cutter holders integrating five functions"; through a mechanical height difference structure and modular loading and unloading design, it realizes the simultaneous integration of three major functions: cutting, dotted line cutting, and creasing on one machine, and can flexibly combine them into a double-line equidistant cutting / creasing working mode; it breaks the limitations of traditional equipment with single function (such as only cutting or only creasing) or requiring complex tool replacement, and integrates five types of tools (left / right cutting blade 32, left / right rotating blade 1901, and middle cutting blade) into one, realizing "one machine with multiple functions".

[0047] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
