Description

Technical Field

[0001] This utility model relates to the field of manual paper cutter technology, specifically a paper cutter with an anti-paper deviation structure. Background Technology

[0002] Paper cutters are mainly divided into manual and automatic types. Automatic paper cutters are usually used in industrial production, while manual paper cutters are usually used in commercial and residential applications, such as cutting paper into various sizes when making finished products, cutting photos, and cutting A4 paper in the office.

[0003] Existing paper cutters typically employ a paper-pressing structure when cutting photo paper, cardstock, A4 paper, and other types of paper. These structures include screw-type, pressure bar-type, and linked pressure plate-type. Screw-type and pressure bar-type machines are convenient for pressing thick paper or stacked paper piles, but for pressing single sheets, the pressing operation is relatively cumbersome, and the structure needs to be reset after each cut before the next cut can be made, making the operation tedious. The linked pressure plate-type machine uses a downward-rotating cutter that simultaneously rotates a pressure plate to press the paper. While convenient for pressing single sheets, it has poor limiting effect on stacked paper piles. This is mainly because the pressure plate rotates downwards, and if the paper pile is thick, the pressure plate may not rotate to a horizontal position before hitting the pile and unable to continue rotating downwards, resulting in a tilted pressure plate and weaker pressing effect. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a paper cutter with an anti-paper deviation structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper cutter with an anti-paper deviation structure, comprising a paper cutting table, a base penetrating one side of the bottom of the paper cutting table, and a base plate penetrating the bottom of the base, with a top rod connected to the top of the base plate by a spring; a pressure plate sleeved on the outside of the top rod, and an anti-slip pad connected to the bottom of the pressure plate by a first Velcro and a second Velcro; an operating lever penetrating one side of the pressure plate, and a screw fixed to one end of the operating lever.

[0006] By adopting the above technical solution, before cutting the paper stack, when it is necessary to cut the paper stack, the user can rotate the control lever to rotate the screw. The control lever acts as an extension, leaving enough space to facilitate the rotation of the control lever and the screw, preventing the pressure plate from blocking the user's hand and causing operational obstruction. After the screw stops rotating and no longer blocks the top rod, the user can slide the pressure plate up and down to adjust its height to accommodate paper stacks or sheets of different thicknesses. After adjusting the height of the pressure plate, the user reverses the control lever to reverse the screw. After the screw reverses, it blocks the top rod to prevent the pressure plate from... The top rod moves relative to the other side; if the thickness of this cut is the same as or similar to the thickness of the previous cut, there is no need to adjust the height of the pressure plate; after adjusting the height of the pressure plate, the user manually presses the pressure plate down so that the pressure plate can press the thinner stack of paper or a single sheet of paper tightly. At the same time, the anti-slip pad increases the friction between the pressure plate and the paper, improves the limiting effect on the paper, and effectively reduces the occurrence of paper deviation; when the paper is cut, the user stops operating the pressure plate, and the spring drives the top rod to move upward to lift the pressure plate back to its original position, which facilitates the next paper cut. The operation is simple and convenient.

[0007] Furthermore, the longitudinal section of the top rod is inverted "T" shape, and the top rod is slidably connected to the base.

[0008] By adopting the above technical solution, the pressure plate can be pressed down manually to press it firmly against a thinner stack of paper or a single sheet of paper, preventing the paper from shifting during cutting. After the paper is cut, the operation of the pressure plate is stopped, and the spring drives the top rod to move upward to lift the pressure plate back to its original position, thus facilitating the next paper cutting. The operation is simple and convenient.

[0009] Furthermore, the screw is threadedly connected to the pressure plate, and the screw abuts against the top rod, while the pressure plate and the top rod are slidably connected.

[0010] By adopting the above technical solution, the screw stops pressing against the top rod after rotating. At this time, the height of the pressure plate can be adjusted by sliding the pressure plate to accommodate thicker paper stacks. After adjusting the height of the pressure plate, the screw is reversed by reversing the control lever. After the screw reverses, it presses against the top rod to prevent the pressure plate and the top rod from moving relative to each other.

[0011] Furthermore, the control lever has a "T" shaped cross-section, and the outer ring of the control lever is provided with anti-slip texture.

[0012] By adopting the above technical solution, the rotatable lever can rotate the screw, and the lever acts as an extension, leaving enough space to facilitate the rotation of the lever and the screw, thus avoiding the pressure plate pressing against the user's hand and causing operational obstruction.

[0013] Furthermore, the anti-slip mat is made of silicone rubber material, and the anti-slip mat is detachably connected to the first Velcro by a second Velcro fastener.

[0014] By adopting the above technical solution, while pressing the paper with the pressure plate, the anti-slip pad increases the friction between the pressure plate and the paper, improves the limiting effect on the paper, effectively reduces the occurrence of paper deviation, and when the anti-slip pad is damaged, the second Velcro can be removed to replace the anti-slip pad.

[0015] Furthermore, the first hook and loop fastener is fixedly connected to the bottom of the pressure plate by epoxy resin adhesive or hot melt adhesive, and the second hook and loop fastener is fixedly connected to the anti-slip pad by epoxy resin adhesive, hot melt adhesive or stitching.

[0016] By adopting the above technical solution, the fixing cost is low and the fixing effect is good, effectively preventing the first and second hook and loop fasteners from falling off.

[0017] Furthermore, a paper cutter is connected to one side of the paper cutting table, and a magnetic positioning block is placed on the top of the paper cutting table.

[0018] By adopting the above technical solution, when using the paper, the user places the paper to be cut on the top of the paper cutting table, and positions the paper by the paper cutting table and the magnetic positioning block. Then the user can operate the paper cutter to cut the paper.

[0019] Furthermore, the bottom cross-section of the base is hexagonal, and the top of the base is threadedly connected to the paper cutting table.

[0020] By adopting the above technical solution, users can disassemble the base, bottom plate, spring and top rod downwards by rotating the base with a wrench.

[0021] Furthermore, the bottom of the base plate is provided with a hexagonal groove, and the base plate is threadedly connected to the base.

[0022] By adopting the above technical solution, users can remove and replace the spring and push rod by turning the base plate with an Allen wrench.

[0023] Furthermore, a first rib and a second rib are fixed to the top of the pressure plate, and the top of the second rib is arc-shaped, and the width of the second rib is smaller than the width of the first rib.

[0024] By adopting the above technical solution, the first and second ribs prevent the pressure plate from bending and deforming due to excessive span, which would affect the paper pressing surface. Furthermore, because the second rib is narrower and has a rounded top, it prevents the second rib from injuring the user's hands while ensuring structural strength.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, through the setting of spring, top rod and pressure plate, allows the pressure plate to be pressed down manually, so that it can be pressed tightly against thinner stacks of paper or single sheets of paper, preventing the paper from shifting during cutting. After the paper is cut, the operation of the pressure plate is stopped, and the spring drives the top rod to move upward, thereby lifting the pressure plate back to its original position, which facilitates the next paper cutting. The operation is simple and convenient. Compared with screw and pressure bar paper pressing structures, it is simpler and more convenient to operate when pressing a small number of stacks of paper or single sheets of paper; the structure is simple and the operation is convenient.

[0027] 2. This utility model, through the setting of a control lever and a screw, allows the screw to rotate when paper stacks need to be cut. The control lever extends the screw, leaving sufficient space for rotation of both the control lever and the screw, preventing the pressure plate from obstructing the user's hand and hindering operation. After the screw stops rotating and no longer presses against the top rod, the pressure plate can be slid to adjust its height to accommodate thicker paper stacks. After adjusting the height of the pressure plate, the screw is reversed by reversing the control lever. The reversed screw presses against the top rod, preventing relative movement between the pressure plate and the top rod. Compared to a linkage pressure plate type, this design facilitates the compaction of larger paper stacks, expanding its applicability to handle different usage scenarios.

[0028] 3. This utility model, through the setting of the first hook and loop fastener, the second hook and loop fastener, and the anti-slip pad, while pressing the paper tightly by the pressure plate, increases the friction between the pressure plate and the paper by the anti-slip pad, improves the limiting effect on the paper, effectively reduces the occurrence of paper deviation, and when the anti-slip pad is damaged, the second hook and loop fastener can be peeled off to replace the anti-slip pad; improves the paper pressing effect and facilitates the replacement of the anti-slip pad.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] A paper cutter with a paper offset prevention structure, such as Figures 1-5 As shown, the device includes a paper cutting table 1, a base 4 extending through one side of the bottom of the paper cutting table 1, a base plate 5 extending through the bottom of the base 4, and a top rod 7 connected to the top of the base plate 5 by a spring 6. The top rod 7 has an inverted "T" shaped longitudinal section and is slidably connected to the base 4. A pressure plate 8 is sleeved on the outside of the top rod 7 and is slidably connected to the top rod 7. An anti-slip pad 13 is connected to the bottom of the pressure plate 8 by a first hook and loop fastener 11 and a second hook and loop fastener 12. The first hook and loop fastener 11 is fixedly connected to the bottom of the pressure plate 8 by epoxy resin adhesive or hot melt adhesive, and the second hook and loop fastener 12 is fixedly connected to the bottom of the pressure plate 8 by epoxy resin adhesive. The anti-slip mat 13 is fixedly connected to the pressure plate 8 by adhesive, hot melt adhesive, or stitching. The anti-slip mat 13 is made of silicone rubber and is detachably connected to the first hook and loop fastener 11 via the second hook and loop fastener 12. A control lever 9 runs through one side of the pressure plate 8. The control lever 9 has a "T"-shaped cross-section and anti-slip texture on its outer ring. A screw 10 is fixed to one end of the control lever 9, which is threadedly connected to the pressure plate 8 and abuts against the top rod 7. Before cutting the paper, when it is necessary to cut the paper stack, the user can rotate the control lever 9 to rotate the screw 10. The control lever 9 serves as an extension, providing sufficient space for rotating both the control lever 9 and the screw 10, preventing the pressure plate 8 from obstructing the user's hand and hindering operation. After the screw 10 rotates and stops pressing against the top rod 7, the user can slide the pressure plate 8 up and down to adjust its height to accommodate different thicknesses of paper stacks or sheets. After adjusting the height of the pressure plate 8, the user reverses the control lever 9 to reverse the screw 10. The reversed screw 10 then presses against the top rod 7 to prevent relative movement between the pressure plate 8 and the top rod 7. If the thickness of this cut is different from the previous one... If the cutting thickness is the same or similar, there is no need to adjust the height of the pressure plate 8. After adjusting the height of the pressure plate 8, the user manually presses the pressure plate 8 downward so that it can press the thinner stack of paper or a single sheet of paper tightly. At the same time, the anti-slip pad 13 increases the friction between the pressure plate 8 and the paper, improving the limiting effect on the paper and effectively reducing the occurrence of paper deviation. After the paper is cut, the user stops operating the pressure plate 8. The spring 6 drives the top rod 7 to move upward, thereby lifting the pressure plate 8 back to its original position, which facilitates the next paper cutting. The operation is simple and convenient.

[0039] See Figure 1 In the above embodiment, a paper cutter 3 is connected to one side of the paper cutting table 1, and a magnetic positioning block 2 is placed on the top of the paper cutting table 1. When in use, the user places the paper to be cut on the top of the paper cutting table 1 and positions the paper by the paper cutting table 1 and the magnetic positioning block 2. Then the user can operate the paper cutter 3 to cut the paper.

[0040] Example 2:

[0041] Based on the above embodiment one, the following settings are made to facilitate structural replacement.

[0042] See Figures 2-5 In the above embodiment, the bottom cross-section of the base 4 is hexagonal, the top of the base 4 is threaded to the paper cutting table 1, the bottom of the base plate 5 is provided with a hexagonal groove, and the base plate 5 is threaded to the base 4. When there is structural damage, the user can first rotate the operating lever 9 and pull it out to separate the screw 10 from the top rod 7 and the operating lever 9 from the pressure plate 8. At this time, the user can directly disassemble the pressure plate 8 upwards to facilitate the replacement of the pressure plate 8. The user can also remove the second Velcro 12 to replace the anti-slip pad 13. The user can rotate the base 4 with a wrench to disassemble the base 4, base plate 5, spring 6 and top rod 7 downwards. Then, the user can rotate the base plate 5 with an Allen wrench to remove the spring 6 and top rod 7 for replacement. The operation is reversed during installation.

[0043] Example 3:

[0044] Based on the above embodiment one, the following settings are now adopted to increase structural strength.

[0045] See Figures 1-4 In the above embodiment, a first rib 14 and a second rib 15 are fixed to the top of the pressure plate 8. The top of the second rib 15 is arc-shaped, and the width of the second rib 15 is smaller than the width of the first rib 14. The first rib 14 and the second rib 15 prevent the pressure plate 8 from bending and deforming due to excessive span, which would affect the paper pressing surface. Furthermore, because the second rib 15 is narrower and has an arc-shaped top, the second rib 15 can prevent injury to the user's hands while ensuring structural strength.

[0046] The implementation principle of this utility model is as follows: First, when using it, the user places the paper to be cut on the top of the paper cutting table 1, and positions the paper by the paper cutting table 1 and the magnetic positioning block 2. Then the user can operate the paper cutter 3 to cut the paper.

[0047] Before cutting the paper, when it is necessary to cut the paper stack, the user can rotate the control lever 9 to rotate the screw 10. The control lever 9 acts as an extension, leaving enough space to facilitate the rotation of the control lever 9 and the screw 10, and preventing the pressure plate 8 from blocking the user's hand and causing operational obstruction. After the screw 10 stops rotating and no longer blocks the top rod 7, the user can slide the pressure plate 8 up and down to adjust its height to accommodate paper stacks or sheets of different thicknesses. After adjusting the height of the pressure plate 8, the user reverses the control lever 9 to reverse the screw 10. After the screw 10 reverses, it blocks the top rod 7 to prevent the pressure plate 8 from moving relative to the top rod 7. If the thickness of this cut is the same as or similar to the thickness of the previous cut, it is not necessary to adjust the height of the pressure plate 8.

[0048] After adjusting the height of the pressure plate 8, the user manually presses the pressure plate 8 downwards to press it firmly against thinner stacks or single sheets of paper. Simultaneously, the anti-slip pad 13 increases the friction between the pressure plate 8 and the paper, improving the paper's positioning effect and effectively reducing paper deviation. Furthermore, the first rib 14 and the second rib 15 prevent the pressure plate 8 from bending and deforming due to excessive span, thus affecting the paper pressing surface. Because the second rib 15 is narrower and has a rounded top, it prevents injury to the user's hands while maintaining structural strength. After cutting the paper, the user stops operating the pressure plate 8, and the spring 6 drives the top rod 7 to move upwards, thus lifting and resetting the pressure plate 8 for the next cutting operation. The operation is simple and convenient.

[0049] When structural damage occurs, the user can first rotate the control lever 9 and pull it out to separate the screw 10 from the push rod 7 and the control lever 9 from the pressure plate 8. At this time, the user can directly disassemble the pressure plate 8 upwards for easy replacement. The user can also remove the second Velcro 12 to replace the anti-slip pad 13. The user can use a wrench to rotate the base 4 to disassemble the base 4, base plate 5, spring 6 and push rod 7 downwards. Then, the user can use an Allen wrench to rotate the base plate 5 to remove the spring 6 and push rod 7 for replacement. The installation is the reverse operation.
