Description

Technical Field

[0001] This utility model relates to the field of flatbed creasing and paper cutting machine technology, and in particular to a feeding mechanism and a flatbed creasing and paper cutting machine. Background Technology

[0002] The flatbed creasing and cutting machine (also known as the flatbed creasing and lining machine) is a post-printing processing equipment that integrates die-cutting, creasing, and lining. It is mainly used for precise cutting and creasing of materials such as cardboard, corrugated paper, plastic sheets, and leather.

[0003] A search revealed that patent CN215511353U discloses a flatbed creasing paper cutter with easily adjustable cutting height; however, this device has the following shortcomings in use:

[0004] In use, the paper is placed on a pressing frame to flatten it, and then the cardboard is cut by a cutting blade. However, when multiple pieces of paper need to be cut, it is impossible to ensure that one end of the multiple cardboards is aligned, which can easily lead to inaccurate cutting dimensions. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when paper is placed on a pressing frame to flatten it and then cut by a cutting blade, it is difficult to ensure that one end of multiple pieces of paper is aligned when cutting multiple pieces of paper, which easily leads to inaccurate cutting dimensions. Therefore, this invention proposes a feeding mechanism and a flat-press creasing paper cutter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flatbed creasing and paper cutting machine includes a machine base. An L-plate is fixedly installed on one side of the top of the machine base. A driving component is fixedly installed on one side of the top of the L-plate. The telescopic part of the driving component passes through the top of the L-plate and is fixedly installed on a frame. A blade holder is provided below the frame. Slots are provided at the top and bottom of the blade holder. A paper cutting blade is inserted into the slot. A flipping mechanism is provided on the frame. When the blade needs to be replaced, the flipping mechanism can flip and replace two blades.

[0008] To improve the stability of the tool holder, the frame also includes a fixing mechanism that can fix the tool holder after the blade reverses.

[0009] In one possible design, the flipping mechanism includes a second motor and two rotating shafts. One end of each rotating shaft is fixedly connected to both sides of the tool holder, and the ends of the two rotating shafts that are far apart from each other are rotatably connected to the inner walls of both sides of the frame. One side of the second motor is fixedly connected to one side of the frame, and the output end of the second motor passes through one side of the frame and is fixedly connected to one end of the rotating shaft.

[0010] In one possible design, the fixing mechanism includes a fixing frame, two insert rods and a threaded rod. One end of each of the two insert rods is fixedly connected to the inner wall of one side of the fixing frame. Insertion holes are provided on one side of the tool holder and one side of the frame to facilitate the insertion of the insert rods. The insert rods are inserted into the insertion holes. A nut is embedded in one side of the fixing frame, and the threaded rod is threadedly connected to the nut. An insertion hole is provided on one side of the frame, and one end of the threaded rod is inserted into the insertion hole. A knob for easy rotation is fixedly provided on one end of the threaded rod.

[0011] In one possible design, a connecting plate is fixedly installed on one side of the frame, and a second electric push rod is fixedly installed on the top of the connecting plate. The telescopic part of the second electric push rod passes through the top of the connecting plate and is fixedly installed with a pressure plate for pressing down and fixing when cutting the cardboard.

[0012] In one possible design, the blade holder has four through holes, through which bolts for fixing the blade are inserted. Two round holes are opened on one side of the blade, and one end of the bolt is inserted into the round hole.

[0013] A feeding mechanism for feeding the aforementioned flatbed creasing and cutting paper machine includes an L-shaped baffle for placing cardboard. A groove is provided on the top of the machine base. A lead screw is rotatably connected to the inner walls of both sides of the groove. A first motor for driving the lead screw to rotate is fixedly installed on one side of the machine base. The output end of the first motor passes through one side of the machine base and is fixedly connected to one end of the lead screw. A slider for driving the baffle to move below the blade is slidably connected to the bottom inner wall of the groove. A lead screw nut is embedded in one side of the slider and is threadedly connected to the lead screw. The top of the slider is fixedly connected to the bottom of the baffle. An alignment mechanism is provided on the top of the baffle, which can align multiple cardboards when they are being cut.

[0014] In one possible design, the alignment mechanism includes a fixed block, a first electric push rod, and a first push plate. The bottom of the fixed block is fixedly connected to the top side of the baffle. One end of the first electric push rod is fixedly connected to one side of the fixed block. The bottom of the first push plate is slidably connected to the top of the baffle. The telescopic part of the first electric push rod passes through one side of the fixed block and is fixedly connected to one side of the first push plate.

[0015] In this application, during use, multiple cardboard pieces to be cut are placed on the baffle, with one end of each cardboard aligned with the L-shaped portion of the L-plate. The first electric push rod is activated, its telescopic part pushing the first push plate to align the cardboard pieces, ensuring a neat arrangement. Then, the first motor is activated, driving the lead screw to rotate. The lead screw nut causes the slider to slide along the inner wall of the groove bottom, moving the baffle to a suitable position, placing the cardboard below the blade (adjusting the position according to the cutting size). The drive mechanism is activated, its telescopic part moving the frame closer to the cardboard, preparing for the cutting operation. Then, the second electric push rod is activated, its telescopic part pushing the pressure plate downwards to press and fix the cardboard, preventing movement during cutting and ensuring stability. The drive mechanism then drives the blade downwards to cut the cardboard. When blade replacement is needed, a knob is turned. The movement drives the rotation of the threaded rod, causing one end of the threaded rod to leave the insertion hole of the frame. Pulling the fixing bracket, the insertion rod leaves the insertion hole of the tool holder. Then, the second motor is started, and its output drives the rotating shaft to rotate. The rotating shaft causes the tool holder and blade to rotate 180 degrees. At this point, the insertion rod in the insertion hole of the tool holder is aligned. Pushing the fixing bracket (until it can't be pushed any further, at which point the threaded rod and insertion hole are aligned) inserts the insertion rod into the insertion hole. Then, rotating the knob allows the threaded rod to be inserted into the insertion hole, fixing the tool holder and ensuring stable use of the blade after rotation. The driving component can be one of an electric push rod, a cylinder, or a hydraulic cylinder. The driving component, the first electric push rod, the second electric push rod, the first motor, and the second motor require an external power supply and an external controller for operation. The first and second motors can be stepper motors, with the specific type selected according to actual needs. The material and type of the lead screw and threaded rod can also be selected according to actual needs.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this utility model, the flatbed creasing paper cutter, by setting an alignment mechanism, uses a first electric push rod to push the first push plate to move, which can automatically align multiple cardboards placed on the baffle. When multiple cardboards are cut, the mechanism can ensure that one end of the cardboards is neatly arranged, effectively solving the problem in the prior art that it is impossible to ensure that one end of multiple cardboards is aligned, which easily leads to inaccurate cutting size. This greatly improves the accuracy of cutting size and ensures the quality of paper cutting.

[0018] In this invention, a flatbed creasing and cutting paper cutter utilizes a flipping mechanism. When blade replacement is needed, the flipping mechanism allows for the interchange of two blades. Specifically, a second motor drives a rotating shaft to rotate, causing the blade holder and blades to flip. A fixing mechanism then secures the blade holder, ensuring stable blade operation after flipping. This design avoids the cumbersome blade replacement process of traditional paper cutters, significantly improving blade utilization efficiency, reducing equipment downtime, and increasing production efficiency.

[0019] In this utility model, the flatbed creasing paper cutter uses a fixing mechanism to securely fix the blade holder by inserting a rod into the insertion hole of the blade holder and the frame after the blade is reversed, and then turning the knob to insert the threaded rod into the insertion hole. This fixing method is simple and reliable, ensuring the stability of the blade after reversal and guaranteeing the smooth progress of the paper cutting process.

[0020] In this invention, the alignment mechanism can automatically align multiple cardboard pieces placed on the baffle, ensuring that one end of the cardboard pieces is neatly arranged when multiple cardboard pieces are cut. The flipping mechanism can flip and replace two blades, and the fixing mechanism can fix the blade holder, ensuring the stability of the blades after flipping and guaranteeing the smooth progress of the paper cutting process.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Reference Figure 1-5 A flatbed creasing and cutting paper machine, applicable in the field of flatbed creasing and cutting paper machines, includes: an L-shaped L-plate 2 fixedly installed on one side of the top of the machine base 1 by bolts. The L-plate 2 serves as an important supporting component, and a drive unit 3 is fixedly installed on its top side by welding or bolting. The drive unit 3 can be selected from an electric push rod, a pneumatic cylinder, or a hydraulic cylinder; in this embodiment, an electric push rod is used as an example. The telescopic part of the drive unit 3 extends through the top of the L-plate 2 and is fixedly connected to a frame 7 via a flange, ensuring that the frame 7 can move up and down under the drive of the drive unit 3.

[0030] A blade holder 15 is installed below the frame 7, with slots 14 at both the top and bottom. A paper-cutting blade 12 is inserted into the slot 14, with both sides of the blade 12 fitting snugly against the inner wall of the slot 14. To further secure the blade 12, four through holes are made on the blade holder 15, with two corresponding round holes on one side of the blade 12. A bolt 20 is passed through the through holes and inserted into the round holes, then tightened with a nut to ensure the blade 12 is stably placed on the blade holder 15.

[0031] To enable the replacement of the blade 12, a flipping mechanism is installed on the frame 7. The flipping mechanism includes a second motor 17 and two rotating shafts. One end of each shaft is fixed to one side of the blade holder 15 via a key, and the ends of the shafts that are far apart are rotatably connected to the inner walls of both sides of the frame 7 via bearings. One side of the second motor 17 is fixedly connected to one side of the frame 7 with bolts, and the output end of the second motor 17 passes through one side of the frame 7 and is fixedly connected to one end of the rotating shaft via a coupling. When the blade 12 needs to be replaced, the second motor 17 is started. The output end of the second motor 17 drives the rotating shafts to rotate, causing the blade holder 15 and the blade 12 to flip, thus enabling the replacement of the two blades 12.

[0032] To improve the stability of the tool holder 15 after flipping, a fixing mechanism is installed on the frame 7. The fixing mechanism includes a fixing frame 13, two insert rods 18, and a threaded rod. One end of each insert rod 18 is welded to the inner wall of one side of the fixing frame 13. Insertion holes 19 are provided on one side of the tool holder 15 and one side of the frame 7 to facilitate the insertion of the insert rods 18. A nut is embedded in one side of the fixing frame 13, and the threaded rod is threadedly connected to the nut. Insertion holes are provided on one side of the frame 7. When the blade 12 is flipped 180 degrees, the fixing frame 13 is pushed, causing the insert rods 18 to be inserted into the corresponding insertion holes 19 of the tool holder 15 and the frame 7. Then, the knob 21 is rotated, causing the threaded rod to rotate and insert one end of the threaded rod into the insertion hole, thus fixing the tool holder 15.

[0033] To press and secure the cardboard during cutting, a connecting plate 10 is bolted to one side of the frame 7, and a second electric push rod 16 is bolted to the top of the connecting plate 10. The telescopic part of the second electric push rod 16 extends through the top of the connecting plate 10 and is connected to and secured to a pressure plate 11 via a flange. When the cardboard moves below the blade 12, the second electric push rod 16 is activated, and its telescopic part pushes the pressure plate 11 down to secure the cardboard.

[0034] The feeding mechanism for a flatbed creasing and cutting paper machine includes an L-shaped baffle 6 for placing the cardboard. A groove 8 is formed in the top of the machine base 1, and the inner walls of both sides of the groove 8 are rotatably connected to the same lead screw via bearings. A first motor 9 is bolted to one side of the machine base 1, and the output end of the first motor 9 passes through one side of the machine base 1 and is fixedly connected to one end of the lead screw via a coupling. A slider is slidably connected to the bottom inner wall of the groove 8, and a lead screw nut is embedded in one side of the slider. The lead screw nut is threadedly connected to the lead screw, and the top of the slider is bolted to the bottom of the baffle 6.

[0035] To align multiple cardboard pieces during cutting, an alignment mechanism is provided on the top of the baffle 6. The alignment mechanism includes a fixing block, a first electric push rod 4, and a first push plate 5. The bottom of the fixing block is bolted to one side of the top of the baffle 6. One end of the first electric push rod 4 is bolted to one side of the fixing block, and the bottom of the first push plate 5 is slidably connected to the top of the baffle 6 via a slide rail. The telescopic part of the first electric push rod 4 passes through one side of the fixing block and is bolted to one side of the first push plate 5. Multiple cardboard pieces to be cut are placed on the baffle 6, with one end of the cardboard piece aligned with the L portion of the L-plate 2. The first electric push rod 4 is activated, and its telescopic part pushes the first push plate 5 to move, aligning the multiple cardboard pieces.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive unit 3, the first electric push rod 4, the second electric push rod 16, the first motor 9 and the second motor 17 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
