Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically a paper cutting device. Background Technology

[0002] In the paper processing industry, stack paper cutting devices are widely used in production, printing, packaging and other industries. Traditional cutting equipment usually consists of a feeding mechanism, a cutting blade assembly, a worktable and a paper pressing mechanism. The feeding mechanism feeds the paper onto the worktable, places the paper to be cut at the designated position, the paper pressing mechanism presses the paper, and the cutting blade assembly cuts the paper. After cutting, the paper needs to be transferred batch by batch manually or by a robot.

[0003] However, the stacks of paper after cutting are close to the cutting blade. Whether handled manually or transferred by a robotic arm, they need to frequently approach the cutting area. The operating space is limited and there are safety hazards. In addition, due to the weight of the stacks of paper and the fact that the bottom is in contact with the workbench surface, neither manual handling nor robotic arms have a good point of leverage or gripping, making it inconvenient to handle. Generally, they are transferred in batches, but this will affect work efficiency. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a paper cutting device that uses a pallet to support stacks of paper. After cutting, a cylinder drives the pallet to move obliquely upward along a chute, thereby moving it away from the cutting blade, increasing the operating space, and improving safety. Furthermore, the pallet size is smaller than the size of the cut paper, allowing the paper edges to protrude, facilitating handling and transfer by personnel or robotic arms, making the work convenient and improving work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper cutting device, comprising a worktable, a cutting component, a pair of limiting components, a tray, and a driving component. A pair of support plates are provided at the bottom of the worktable, and gate-shaped plates span the front and rear of the worktable. The cutting component is positioned at the top center of the gate-shaped plates and is capable of cutting stacks of paper. The pair of limiting components are respectively positioned on the gate-shaped plates near the worktable, and are capable of limiting the front and rear movement of the stack of paper. A notch is provided on the worktable corresponding to the center of the right side of the cutting component, and the width of the notch... The width of the notch is less than the width of the stack of papers. The front and rear ends of the notch are provided with inclined grooves. The right side of the groove is higher than the left side. The front and rear ends of the tray are respectively provided with a pair of sliders. Each pair of sliders is slidably connected to the groove. The size of the tray is smaller than the size of the stack of papers after cutting. When the slider of the tray is located at the leftmost end of the groove, the upper surface of the tray is flush with the upper surface of the worktable. When the slider of the tray is located at the rightmost end of the groove, the upper surface of the tray is higher than the upper surface of the worktable. The drive assembly is located between a pair of support plates and the drive end is connected to the bottom of the tray. The drive assembly can drive the tray to move along the groove.

[0006] Preferably, the drive assembly includes a cylinder, a fixed rod, and a shaft hinge. The output end of the cylinder is hinged to the center position of the bottom of the support plate via the shaft hinge. The fixed rod is fixedly disposed between a pair of support plates, and the base end of the cylinder is rotatably connected to the center position of the fixed rod.

[0007] Preferably, the limiting assembly includes a threaded rod, a pair of limiting rods, and a limiting plate. The threaded rod passes through the portal plate and is screwed to the portal plate. The pair of limiting rods are located on both sides of the threaded rod and axially move through the portal plate. A fixing plate is connected to one end of the inner side of the threaded rod and the pair of limiting rods. The limiting plate is disposed on the inner side wall of the fixing plate.

[0008] Preferably, the inner sidewall of the limiting plate and the edge corresponding to the incoming material side are provided with a chamfer.

[0009] Preferably, the upper surface of the pallet and the edge corresponding to the incoming material side are chamfered.

[0010] This utility model provides a paper cutting device, which has the following beneficial effects:

[0011] 1. This utility model uses a pallet to support stacks of paper. After cutting, the pallet is moved obliquely upward along the slide by a cylinder, thereby moving the stacks of paper away from the cutting components, increasing the operating space, improving safety, and the pallet size is smaller than the size of the paper after cutting, with the paper edges exposed, which is convenient for personnel or robotic arms to handle and transfer, making the work convenient and improving work efficiency.

[0012] 2. In this utility model, the upper edge of the pallet on the side corresponding to the incoming material is chamfered to prevent stacks of paper from rubbing against the upper edge of the pallet when they enter. Similarly, the edge of the limiting plate on the side corresponding to the incoming material is chamfered. In addition, the distance between the limiting plates is adjusted by the adjusting component to accommodate paper cutting of different widths. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] like Figure 1-4As shown, a paper cutting device includes a worktable 1, a cutting component 11, a pair of limiting components, a tray 3, and a driving component. A pair of support plates 9 are provided at the bottom of the worktable 1, and a gate-shaped plate 10 spans the worktable 1. The cutting component 11 is located at the top center of the gate-shaped plate 10 and can cut stacks of paper. The pair of limiting components are respectively located on the gate-shaped plate 10 near the worktable 1, and can limit the forward and backward movement of the stack of paper. A notch 2 is provided on the right center of the worktable 1 corresponding to the cutting component 11. The width of the notch 2 is smaller than the width of the stack of paper. Inclined grooves 5 are provided on the front and rear ends of the notch 2, with the right side of the groove 5 higher than the left side. A pair of sliders 4 are respectively provided on the front and rear ends of the tray 3, and each pair of sliders 4 is slidably connected to the groove 5. The size of the tray 3 is smaller than the size of the stack of paper after cutting. When the sliders 4 of the tray 3 are located at the leftmost end of the groove 5, the upper surface of the tray 3 is flush with the upper surface of the worktable 1. At the rightmost end, the upper surface of the pallet 3 is higher than the upper surface of the worktable 1. The driving assembly is disposed between a pair of support plates 9 and its driving end is connected to the bottom of the pallet 3. The driving assembly can drive the pallet 3 to move along the slide groove 5. The driving assembly includes a cylinder 6, a fixed rod 7, and a shaft hinge 8. The output end of the cylinder 6 is hinged to the center position of the bottom of the pallet 3 through the shaft hinge 8. The fixed rod 7 is fixedly disposed between a pair of support plates 9, and the base end of the cylinder 6 is rotatably connected to the center position of the fixed rod 7. The limiting assembly includes... The system includes a threaded rod 13, a pair of limiting rods 14, and a limiting plate 12. The threaded rod 13 passes through the portal plate 10 and is screwed to it. The pair of limiting rods 14 are located on both sides of the threaded rod 13 and axially move through the portal plate 10. A fixing plate 15 is connected to one end of the inner side of the threaded rod 13 and the pair of limiting rods 14. The limiting plate 12 is disposed on the inner side wall of the fixing plate 15. The inner side wall of the limiting plate 12 and the edge corresponding to the material receiving side are chamfered. The upper surface of the pallet 3 and the edge corresponding to the material receiving side are also chamfered.

[0020] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0021] According to the instruction manual Figure 1-4 As can be seen, the cutting component 11 in this utility model includes a cutting blade, a pressing mechanism and a moving mechanism, which adopts the prior art; the stack of paper is fed by an external feeding mechanism, which can be a feeding mechanism that pushes the paper on the left side of the worktable 1, which adopts the prior art; the cutting length of the stack of paper can be achieved using sensor technology, which is also the prior art.

[0022] In operation, the drive assembly positions the tray 3 at the leftmost end, with its upper surface flush with the upper surface of the worktable 1. Stacks of paper are conveyed from left to right to the designated position. Because the width of the notch 2 is smaller than the width of the stack of paper, the stack can be stably conveyed on the worktable 1 without edge collapse affecting cutting. At this point, the stack of paper is perfectly positioned on the tray 3. The notch 2 and the groove 5 can be designed according to the cutting length of the stack of paper. Those skilled in the art can easily control the position of the tray 3 through this design. The stack of paper is then cut by the cutting assembly 11. The cutting process is existing technology and will not be described further here. The stack of papers on the right side of the cutting assembly 11 needs to be moved. At this time, the drive assembly is activated, moving the pallet 3 along the slide 5. Since the right side of the slide 5 is higher than the left, the pallet 3 moves the stack of cut papers to the right while simultaneously raising them, ensuring the bottom of the stack is above the upper surface of the worktable 1. Then, personnel or an external robotic arm can remove the stack of cut papers from the pallet 3. Because the pallet 3 is smaller than the stack of cut papers, the edges of the lifted stack are in an airborne state, serving as a point of leverage for personnel or robotic arms, facilitating gripping and transportation, and improving work efficiency. Furthermore, the rightward movement of the stack of papers by the pallet 3 moves it away from the cutting area of ​​the cutting assembly 11, increasing operating space and improving safety. It should be noted that a pair of sliders 4 must be installed on each side of the pallet 3. Besides limiting the sliding movement, these sliders must also ensure that the pallet 3 remains horizontal and cannot rotate. Alternatively, sliders 4 designed to prevent rotation can be selected, such as a combination of dovetail grooves and dovetail blocks. The tension between stacks of paper will stabilize the paper during movement. Of course, if you are worried that the top of the stack of paper will fly off, you can temporarily place a heavy object on top, depending on the actual situation.

[0023] The drive assembly includes a cylinder 6, a fixed rod 7, and a shaft hinge 8. The output end of the cylinder 6 is hinged to the center of the bottom of the pallet 3 via the shaft hinge 8. The fixed rod 7 is fixedly positioned between a pair of support plates 9, and the base end of the cylinder 6 is rotatably connected to the center of the fixed rod 7. During operation, the cylinder 6 extends, causing the moving plate to move along the slide 5. In practical use, one method is to set a straight section at one end of the right side of the slide 5. After the cylinder 6 pushes the pallet 3 and the stack of papers to the straight section, it can provide vertical support for the pallet 3, resulting in better stability during transport. Another method is to set the cylinder 6 and the slide 5 in a straight line, without any hinge or rotatable connection between the two ends of the cylinder 6. The force applied to the pallet 3 is also along the slide 5, ensuring stable force distribution.

[0024] The limiting assembly includes a threaded rod 13, a pair of limiting rods 14, and a limiting plate 12. The threaded rod 13 passes through and is screwed onto the portal plate 10. The pair of limiting rods 14 are located on both sides of the threaded rod 13 and axially move through the portal plate 10. A fixing plate 15 is connected to the inner end of the threaded rod 13 and the pair of limiting rods 14. The limiting plate 12 is disposed on the inner wall of the fixing plate 15. Rotating the threaded rod 13 can drive the limiting plate 12 to move inward or outward, thereby adjusting the distance between the pair of limiting plates 12, suitable for cutting stacks of paper of different widths. Here, the design of the limiting plate 12 can leave a notch 2 for the allowance position of the cutting blade in the cutting assembly 11, depending on the actual situation. To prevent the stack of paper from rubbing against the feeding end of the limiting plate 12, a chamfer can be provided on the inner wall of the limiting plate 12 and on the edge corresponding to the feeding side. Here, the feeding side or feeding end is the left side of the worktable 1.

[0025] The upper surface of pallet 3 and the edge corresponding to the incoming material side are chamfered, as above, to avoid rubbing against the stack of papers and affecting the conveying.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
