Description

Technical Field

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

[0002] In daily life and production, dividing food or ingredients into parts of suitable shape and size is a common daily need. For example, cutting a whole rice cake or a whole cucumber into slices makes it easier to cook later.

[0003] Chinese design patent for a rice cake knife (CN305183347S) discloses a cutting tool structure, in which the white part is a boss supporting the object to be cut, and the metal part is a gate. During use, the object on the boss is cut by opening and closing the gate. Although this type of knife has a cutting function, during the cutting process, because the gate needs to act on the boss to cut the object, some debris from the boss will be cut off and mixed into the object being cut. In addition, because the hand needs to feed the object to be cut towards the gate, it is easy to cut the hand if not operated properly. Furthermore, the consumable blade on the gate will need to be replaced after a long period of use due to reduced sharpness. However, the consumable blades used on existing gates are often only consumed in the middle part of the blade, while the two ends of the blade are not consumed because they are not used. Therefore, there is a waste of materials when replacing the consumable blade. Utility Model Content

[0037] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0038] Please see Figure 1-7The cutting tool shown includes a support platform 1, a safety baffle 2, and a gate assembly 3. The support platform 1 includes a placement part 11 and a gate mounting part 12 disposed on one side of the placement part 11. The upper end face of the placement part 11 near the gate mounting part 12 has a blade clearance groove 111. The safety baffle 2 is disposed on the upper end face of the placement part 11 near the gate mounting part 12. The safety baffle 2 has a cutting channel 21 for the object to be cut to pass through. The gate assembly 3 is configured to rotate around one end of the gate mounting part 12. The gate assembly 3 includes a consumable blade 31. The length of the consumable blade 31 is set to cover the cutting channel 21. During cutting, the cutting edge of the consumable blade 31 enters the blade clearance groove 111.

[0039] Specifically, the placement part 11 can be a planar structure or a platform with a groove for stably placing the object to be cut; the blade clearance groove 111 can be a straight groove or an arc or wave-shaped groove, its essence is to match the shape of the consumable blade 31 and make clearance in order to accommodate the cutting edge of the consumable blade 31; the safety baffle 2 can be a fixed baffle or an adjustable baffle for protecting the operator's hands; the guillotine mounting part 12 can be a fixed structure or an adjustable angle structure to adapt to different cutting needs.

[0040] In practical use, this utility model, by setting a safety baffle 2 and a blade avoidance groove 111, avoids the situation where debris and fragments cut from the support platform 1 are mixed into the object being cut during the cutting process. At the same time, the safety baffle 2 protects the operator's hand safety, avoiding the risk of hand injury when the hand is handed to the cutter assembly 3 through the cutting channel 21. The rotation design of the cutter assembly 3 and the length of the consumable blade 31 covering the cutting channel 21 ensure the completion of the cutting action and the effective use of the blade, reducing the length of the consumable blade 31 outside the cutting channel 21, thereby reducing the cost of the consumable blade 31. Through the above solutions, material waste is reduced, operational safety is improved, and it is suitable for the precise cutting of food or materials.

[0041] Please continue reading. Figure 2 , Figure 3 The switch mounting part 12 includes a switch limiting body 121 disposed in the placement part 11, and a column 122 disposed at one end of the switch limiting body 121; the column 122 includes a rotating shaft 1221 disposed at the upper end; the switch assembly 3 is configured to be movably connected to the rotating shaft 1221.

[0042] Specifically, the knife switch limiter 121 is used to limit the range of motion of the knife switch assembly 3 to prevent excessive rotation from causing the cutting position to deviate; the column 122 is fixed to one end of the knife switch limiter 121 as a support structure, and the rotating shaft 1221 at its top is rotatably connected to the knife switch assembly 3; the rotating shaft 1221 can be a metal shaft with bearings or a high-strength plastic shaft to achieve low-friction rotation; the knife switch assembly 3 cooperates with the rotating shaft 1221 through the connecting part 33, so that the knife switch assembly 3 can perform cutting action with the rotating shaft 1221 as the center; the knife switch limiter 121 can be designed as an L-shaped or T-shaped structure to enhance the limiting effect on the knife switch assembly 3; the column 122 and the knife switch limiter 121 can be connected by bolts or integrally formed to ensure structural stability.

[0043] Therefore, by setting the gate limiter 121 and the column 122 with the rotating shaft 1221, precise rotation control of the gate assembly 3 is achieved. The gate limiter 121 prevents the gate assembly 3 from being excessively pressed down, ensuring the consistency of the cutting depth.

At the same time, the connection method of the rotating shaft 1221 facilitates the maintenance and replacement of the gate assembly 3, extending the service life of the tool.

[0044] Please continue reading. Figure 2 , Figure 3 , Figure 5 The knife switch assembly 3 includes a hand-held part 32, a connecting part 33, and a blade mounting part 34; the connecting part 33 is rotatably connected to the rotating shaft 1221 so that the knife switch assembly 3 can perform a cutting action with the rotating shaft 1221 as the center; the blade mounting part 34 is disposed between the hand-held part 32 and the connecting part 33; the blade mounting part 34 has a mounting port 341; the consumable blade 31 is detachably connected to the mounting port 341.

[0045] Specifically, the handheld part 32 is used by the operator to hold and apply cutting force; the connecting part 33 includes a connecting end 331 connected to the rotating shaft 1221 and an extension section 332 disposed between the connecting end 331 and the blade mounting part 34; the length of the extension section 332 can be adjusted according to actual needs to change the cutting torque, and by setting the extension section 332, the distance between the connecting end 331 and the blade mounting part 34 can be filled, thereby reducing the ineffective length of the consumable blade 31 and reducing the cost of the consumable blade 31; the mounting port 341 of the blade mounting part 34 is used to fix the consumable blade 31, and the mounting port 341 can be set as a rectangular or U-shaped groove structure; the consumable blade 31 is fixed in the mounting port 341 by fasteners 3423, which can be screws or snap-fit ​​structures; as a preferred embodiment, guide grooves can be provided on both sides of the mounting port 341, and the consumable blade 31 is inserted along the guide grooves and fixed by fasteners 3423.

[0046] Thus, the modular design enables quick replacement of the consumable blade 31; the rotating connection structure of the connecting part 33 makes the cutting action smoother; the design of the extension section 332 optimizes the torque transmission efficiency and reduces the ineffective length of the consumable blade 31; the detachable connection of the blade mounting part 34 solves the problem of blade material waste in traditional tools. The operator can replace only the middle part of the consumable blade 31 according to the actual wear condition, thereby significantly reducing the cost of consumables while ensuring cutting accuracy. Moreover, the replacement process does not require professional tools, improving the ease of use.

[0047] Please continue reading. Figure 2 , Figure 3 , Figure 5 The blade mounting part 34 is constructed in a U-shape. The blade mounting part 34 includes two blade fixing units 342 disposed on both sides of the upper end of the mounting port 341, and a guide block 343 disposed at the lower end of the mounting port 341. The consumable blade 31 is fixed to the mounting port 341 by the two blade fixing units 342. The cut object cut by the consumable blade 31 slides down through the guide block 343.

[0048] Specifically, the structural design of the U-shaped blade mounting part 34 allows the consumable blade 31 to be stably installed in the mounting opening 341; two blade fixing units 342 are located on both sides of the upper end of the mounting opening 341, and the consumable blade 31 is fixed in the mounting opening 341 by fasteners 3423; as a preferred embodiment, the blade fixing unit 342 may include a mounting block 3421, a thickness control piece 3422 disposed on the mounting block 3421 and the consumable blade 31, and a fastener 3423 passing through the mounting block 3421 and the thickness control piece 3422 and connected to the consumable blade 31, wherein the thickness control piece 3422 is used to control the thickness of the cut object; the guide block 343 is located at the lower end of the mounting opening 341 and is used to guide the cut object to slide down, avoiding the accumulation of cut material near the blade mounting part 34. For example, the guide block 343 may adopt a bevel design so that the cut object can slide smoothly to the designated position.

[0049] Thus, through the cooperation of the U-shaped blade mounting part 34, the blade fixing unit 342 and the guide block 343, the stable installation of the consumable blade 31 and the smooth sliding of the material after cutting are achieved, and the problem of material accumulation during the cutting process is avoided, which improves the cutting efficiency and ease of use. At the same time, the design of the blade fixing unit 342 ensures the installation accuracy of the consumable blade 31 and extends the service life of the blade. The setting of the guide block 343 further optimizes the handling of the material after cutting and reduces the need for manual intervention.

[0050] Please continue reading. Figure 2 , Figure 3 , Figure 5 The connecting part 33 includes a connecting end 331 connected to the rotating shaft 1221 and an extension section 332 disposed between the connecting end 331 and the blade mounting part 34.

[0051] Specifically, the connecting end 331 is rotatably connected to the rotating shaft 1221 through a bearing or bushing structure, so that the gate assembly 3 can perform cutting action around the rotating shaft 1221; the extension section 332 can be integrally formed with the blade mounting part 34, or it can be a separate structure, such as a metal tube or a plastic rod, and its length is designed according to the cutting stroke requirements, and the cross-sectional shape can be circular, rectangular or polygonal; as a preferred embodiment, the extension section 332 is fixedly connected to the connecting end 331 by welding or bolts, and is integrally formed or detachably connected to the blade mounting part 34.

[0052] Please continue reading. Figure 2 , Figure 3 , Figure 4 , Figure 5The guillotine limiter 121 includes a limit block 1211 disposed on the upper end face; when the lower end face of the blade mounting part 34 contacts the limit block 1211, the cutting edge of the consumable blade 31 enters the blade clearance groove 111.

[0053] Specifically, the limiting block 1211 is fixed to the upper end face of the knife switch limiting body 121. Its height is precisely calculated so that when the knife switch assembly 3 rotates downward until the blade mounting part 34 contacts the limiting block 1211, the cutting edge of the consumable blade 31 just enters the blade clearance groove 111 and does not contact the peripheral wall of the blade clearance groove 111. Furthermore, the cutting edge of the consumable blade 31 is located below the upper end face of the placement part 11. The limiting block 1211 can be made of metal or high-strength plastic material, and its contact surface can be designed as a flat surface or a composite surface with buffer material. As a preferred embodiment, the limiting block 1211 is fixed to the knife switch limiting body 121 by bolts, which facilitates adjustment of its installation height.

[0054] Therefore, by setting the limit block 1211, this technical solution can precisely control the downward stroke of the guillotine assembly 3, ensuring that the cutting edge of the consumable blade 31 is fully inserted into the blade clearance groove 111 during cutting, which not only ensures the cutting effect, but also avoids the direct collision between the blade and the support platform 1 to generate debris.

[0055] Please continue reading. Figure 4 This further includes a reserved space 4 disposed between the blade mounting portion 34 and the safety baffle 2.

[0056] Specifically, the reserved space 4 is used to reserve installation space for the thickness control plate 3422. By replacing the thickness control plate 3422 with different thicknesses, the position of the consumable blade 31 can be adjusted, thereby adjusting the cutting thickness of the object being cut.

[0057] Please continue reading. Figure 2 The placement part 11 includes a support shell 112 and multiple reinforcing ribs 113 arranged in an alternating pattern inside the support shell 112; the support shell 112 includes an marking groove 1121 arranged on the upper end face.

[0058] Specifically, the support shell 112 is made of rigid plastic or metal, and the interior is formed by injection molding or welding to create an interlaced reinforcing rib structure 113. The distribution density of the reinforcing ribs 113 is adjusted according to the size and load-bearing requirements of the support platform 1. The marking groove 1121 is formed by die stamping or engraving, and the depth is controlled within the range of 0.5-2mm. It is used to place product markings, corporate trademarks or operation instruction labels. The wall thickness of the support shell 112 is designed to be 2-4mm, which reduces the overall weight while ensuring structural strength.

[0059] The design of the support shell 112 and the reinforcing ribs 113 together reduces the overall weight and significantly improves the bending resistance of the support platform 1. The staggered reinforcing ribs 113 can effectively disperse the impact force generated during cutting and prevent local deformation of the support shell 112. The marking groove 1121 facilitates quick identification of the tool model and usage specifications, avoiding equipment damage caused by improper operation. Thus, while ensuring the rigidity of the support platform 1, the material usage is optimized, and the standardized marking system improves the safety of use. In specific implementation, the reinforcing ribs 113 can be arranged in a radial or concentric circle pattern, and the marking groove 1121 can also be designed as a dedicated receiving structure for barcodes or QR codes.

[0060] Please continue reading. Figure 6 The support platform 1 further includes a reserved hollow column 13 disposed at the bottom of the placement part 11 and / or the switch mounting part 12.

[0061] Specifically, the reserved hollow column 13 is constructed as a hollow cylindrical structure, and its material can be the same engineering plastic or metal material as the support platform 1. In specific implementation, the reserved hollow column 13 can be integrally formed with the support platform 1 by injection molding, or fixed to the bottom of the support platform 1 by detachable methods such as threaded connection or snap-fit ​​connection. As a preferred embodiment, structures can be added inside the reserved hollow column 13 as needed.

[0062] By adding a pre-reserved hollow column 13 at the bottom of the support platform 1, two levels of improvement can be achieved: First, the hollow structure reduces the overall weight while ensuring support strength, making it easier to handle and operate; second, the column design provides a physical interface for subsequent functional expansion. For example, the workbench can be fixed by adding suction cups or anti-slip rubber plugs to the hollow column, or the height can be adjusted by inserting a bracket. This maintains the integrity of the basic structure and reserves physical conditions for functional expansion in different usage scenarios.

[0063] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
