Description

Technical Field

[0001] This utility model relates to the field of food processing machinery technology, specifically a noodle cutting device that can protect the blade. Background Technology

[0002] As a traditional staple food, dried noodles often need to be cut into specific lengths during the later stages of production and food processing. Currently, cutting noodles mainly relies on two methods: manual operation and simple mechanical assistance.

[0003] In existing technology, operators typically place bundles of noodles on a fixed, rigid flat surface and then cut them vertically with a noodle cutter. The drawbacks of this method are obvious: the blade tip directly and violently impacts the hard surface. Repeated impacts over time easily cause chipping, rolling, and other damage to the blade, significantly shortening its lifespan and increasing maintenance and replacement costs. To avoid direct blade impact, some improvements have been made, such as leaving a fixed gap between two platforms so the blade can fall into the gap without contacting the platform. However, this rapid downward movement of the blade applies a downward force to the cut surface, causing the noodles to generate torque around the edge of the flat surface. This can cause the freshly cut noodle segments to rotate, bounce, or even scatter out of the work area, affecting work efficiency, creating clutter, and potentially leading to product waste. Utility Model Content

[0004] The purpose of this invention is to provide a noodle cutting device that can protect the blade, so as to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a noodle cutting device that can protect the blade, comprising a fixed platform, at least three hollow support columns fixedly connected to the bottom of the fixed platform, wherein a horizontal support rod is fixedly connected to the side of each of two hollow support columns, and two connecting columns are passed through the upper surface of each horizontal support rod. A movable platform is rotatably connected to the end of each connecting column away from the horizontal support rod via a bearing, and the movable platform is supported by the connecting columns to a horizontal state and is in close contact with one side of the fixed platform; a blade groove is formed on the upper part of the side of the fixed platform and the movable platform that is in close contact with each other, the blade groove being used to receive the descending blade during cutting; a solid support column is axially slidably connected to the end of each hollow support column away from the fixed platform, and a base plate is fixedly connected to the end of each solid support column away from the hollow support column; a spring is provided on the outside of each solid support column, the spring providing a pushing or pulling force between the base plate and the hollow support column; a buffer structure is provided between the solid support column and the hollow support column. Preferably, the buffer structure includes a rubber ring, which is fixedly disposed on the bottom surface of the hollow support column, and the solid support column passes through the hollow circle in the middle of the rubber ring.

[0006] Preferably, the buffer structure includes a cavity disposed in a hollow support column, the solid support column completely penetrating the cavity, and a damping block is fixedly disposed on the outer side of the portion of the solid support column located inside the cavity. The damping block divides the cavity into upper and lower chambers. A convection gap is reserved between the damping block and the inner wall of the cavity, and the two chambers are connected through the convection gap. The cavity is filled with a filling liquid.

[0007] Preferably, the connecting column is connected to the horizontal support rod via a rack and pinion. The horizontal support rod is equipped with a motor and a control system. The control system can control the motor to make the connecting column move vertically up and down to adjust the tilt of the movable platform.

[0008] Preferably, the inner wall of the blade groove is fixedly fitted with a protective pad made of soft material.

[0009] Preferably, a first protective cover and a second protective cover are fixedly connected to the fixed platform and the movable platform, respectively, to prevent the noodles from being pressed up by the blade.

[0010] Preferably, the hollow support columns are four in a square arrangement, with a first reinforcing crossbar and a second reinforcing crossbar between every two adjacent hollow support columns. The first reinforcing crossbar and the second reinforcing crossbar are perpendicular to each other and not on the same plane.

[0011] This utility model provides an improved noodle cutting device that protects the blade, which has the following improvements and advantages compared with the prior art: Firstly, the blade of this utility model does not cut directly onto a hard platform, but rather falls into a blade groove formed by the splicing of two platforms. When the impact force is too great, the entire platform will move downwards, effectively absorbing and dissipating kinetic energy through springs and buffer structures (such as rubber rings or hydraulic damping), transforming the violent rigid collision into a flexible buffering action. This fundamentally avoids problems such as blade chipping and rolling, and greatly extends the service life of the cutting tool. Secondly, this utility model provides an effective downward buffer stroke. After the blade cuts the noodles, the platform sinks downward. Due to inertia, the noodles will leave the platform and remain temporarily suspended in the air. The noodles that leave the platform lose the fulcrum for generating torque and will not rotate. Then, they will be caught by the protective cover that moves downward at the same time, which prevents the cut noodle segments from rotating, bouncing or scattering due to uneven force, thus ensuring the cleanliness of the work area and the neatness of the products.

[0012] Thirdly, the platform can be tilted electrically or manually, and the cut noodles can automatically slide down to the collection area by gravity, eliminating the need for manual handling, realizing semi-automatic operation, improving production efficiency, and reducing the potential contamination from human contact with the product.

[0015] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] This utility model provides a general utility model through improvements. The technical solution of this utility model is as follows: like Figures 1-5 As shown, a noodle cutting device that protects the blade includes a fixed platform 1 and a movable platform 2. The bottom of the fixed platform 1 is vertically connected to at least three hollow support columns 4 (preferably four in a rectangular arrangement) by welding or bolting. A horizontal support rod 5 is fixedly connected to the outer side of each of two opposing hollow support columns 4.

[0017] Each horizontal support rod 5 has two vertically mounted connecting columns 501. The lower end of the connecting column 501 passes through the horizontal support rod 5 in a height-adjustable manner, while its upper end is rotatably connected to the bottom surface of the movable platform 2 via a bearing or a hinged bearing seat. By adjusting the height of the connecting column 501, the movable platform 2 can be supported to a horizontal state, and one side of it can be closely attached to the corresponding side of the fixed platform 1.

[0018] Above the adjacent side edges of the two platforms, a continuous cutting groove 3 is milled or cast together. The width and depth of this groove are slightly greater than the cutting edge thickness of the face cutter, serving to guide and accommodate the cutting edge during the face cutting process, preventing the cutting tip from directly impacting the platform surface. Each hollow support column 4 has a solid support column 8 axially slidably connected to its lower end. The lower end of the solid support column 8 is fixedly connected to a common base plate 15. A spring 9 is fitted around the outside of the solid support column 8. The upper end of the spring 9 presses against the bottom end of the hollow support column 4, and the lower end presses against the upper surface of the base plate 15, thereby continuously providing upward support force. Furthermore, a buffer structure 10 is provided between the solid support column 8 and the hollow support column 4 to provide damping during rapid downward pressure and dissipate impact energy. like Figure 2 As shown, the buffer structure 10 includes a rubber ring 11. The rubber ring 11 is fixedly mounted on the bottom end face of the hollow support column 4 by bonding or interference fit. A hollow circular hole is formed in the center of the rubber ring 11, the diameter of which is slightly smaller than the diameter of the solid support column 8. The solid support column 8 passes through this circular hole like a piston rod.

[0019] When the platform is impacted and sinks, the solid support column 8 experiences intense compression and friction with the inner wall of the rubber ring 11, causing the rubber ring 11 to undergo elastic deformation. This friction and deformation generate significant resistance, rapidly converting the kinetic energy of the sinking into frictional heat and elastic potential energy, thus providing an effective buffering effect. Upon rebound, the elasticity of the rubber ring 11 also helps the platform to return to its original position smoothly.

[0020] Example 2 provides another, higher-performance buffer structure 10 implementation scheme, such as... Figure 4 , Figure 5 As shown, the lower part of the hollow support column 4 is designed as a sealed cavity 12 filled with hydraulic oil or high-viscosity damping grease. The solid support column 8, like a piston rod, completely penetrates this cavity 12. A damping block 13 is fixedly installed on the surface of the section of the solid support column 8 located inside the cavity 12. The outer diameter of the damping block 13 is very close to the inner diameter of the cavity 12, but a small convection gap 14 is reserved around its perimeter. The damping block 13 divides the cavity 12 into two chambers, upper and lower, connected only by the convection gap 14.

[0021] As the platform descends, the damping block 13 moves downwards, forcing the filling fluid in the lower chamber to flow at high speed through the narrow convection gap 14 to the lower-pressure upper chamber. The fluid's viscous resistance is extremely high, which can very smoothly and efficiently convert the impact kinetic energy into heat energy for dissipation, providing an extremely stable buffering effect. During the return stroke, the fluid flows in the opposite direction, similarly generating damping to prevent the platform from vibrating due to excessively rapid resetting.

[0022] Furthermore, the connecting column 501 includes a rack. A small motor (not shown) and gears driven by the motor are installed in the internal cavity 12 of the horizontal support rod 5. The motor is connected to a control system. After a cutting operation is completed, the operator presses a button, the control system issues a command, the motor starts, and the gears drive the racks of the four connecting columns 501 on both sides to move vertically. Because the movable platform 2 is rotatably connected, this causes it to tilt, and the cut noodle segments automatically slide into the collection basket on the side by gravity. After unloading, the motor rotates in the opposite direction, restoring the movable platform 2 to a horizontal state.

[0023] Furthermore, a protective pad made of soft material is fixedly embedded on the inner wall of the blade groove 3, which is formed by the fixed platform 1 and the movable platform 2, by means of bonding or insert molding. This pad can greatly reduce the coefficient of friction and impact stress when the blade side contacts the groove wall. Even if the blade moves slightly in the groove, it can be effectively absorbed and contained by the soft material, thus preventing the blade from being scratched or worn to the greatest extent.

[0024] Furthermore, a first protective cover 101 is vertically fixed to the edge of the upper surface of the fixed platform 1. Similarly, a second protective cover 201 is vertically fixed to the edge of the upper surface of the movable platform 2. These two protective covers can be made of transparent acrylic sheets or metal mesh, serving both as barriers and allowing for observation. When the blade cuts downwards, it may bend the noodles downwards, causing their ends to curl up. The protective covers effectively prevent the curled-up noodles from rising and confine them within the platform area. More importantly, when the entire platform assembly is lowered for cushioning, the protective covers also descend synchronously, catching and gathering any noodle segments that are temporarily suspended in the air due to inertia, completely preventing them from scattering.

[0025] Further, the hollow support columns 4 consist of four columns, located at the four corners of the rectangle. To strengthen the connection between them, a first reinforcing crossbar 6 and a second reinforcing crossbar 7 are welded or bolted between adjacent hollow support columns 4. The first reinforcing crossbar 6 is collinear with the horizontal support column 5, and the second reinforcing crossbar 7 is positioned at a higher position, with the two columns perpendicular to each other. This spatially staggered structure effectively resists force couples and torques from different directions, prevents the frame from deforming under repeated impacts, and ensures synchronous movement of the four support points.

[0026] Working principle: When the entire device is in a static initial state, the fixed platform 1 and the movable platform 2 are supported at a preset working height under the preload thrust of the spring 9. The movable platform 2 is adjusted to a horizontal state through the connecting column 501, and its side is in close contact with the side of the fixed platform 1. The blade grooves 3 on the upper surfaces of the two are aligned to form a complete guide groove, and a bundle of noodles to be cut is placed horizontally on the upper surfaces of the fixed platform 1 and the movable platform 2.

[0027] Swing or use the machine to start the cutting blade, and the blade quickly cuts down in a direction perpendicular to the noodle. After cutting the noodle, the tip and side edge of the blade smoothly enter the blade groove 3 formed by the splicing of two platforms. At this time, if the downward cutting impact force is large, the blade will not stop abruptly as if it were hitting a rigid platform. Instead, the impact force will be transmitted through the platform to the entire support frame. This impact force will overcome the elastic force of the spring 9 and push the hollow support column 4 to slide downward along the axis of the solid support column 8. The device changes from static to dynamic sinking. The kinetic energy of the blade is converted into the elastic potential energy of the spring 9 and the heat energy consumed by the buffer structure 10 (such as the friction of the rubber ring 11 or the viscous resistance of the hydraulic damping fluid). The blade experiences a "soft landing," avoiding damage caused by rigid collision. The sinking of the platform causes the newly cut noodle segment to be briefly suspended in the air due to inertia, losing the fulcrum (i.e., the platform surface) that generates rotational torque. Meanwhile, the first protective cover 101 and the second protective cover 201, which descend synchronously with the platform, will catch or guide these noodle segments like a "receiving plate," thereby effectively preventing them from rotating, bouncing, and scattering.

[0028] Once the impact energy is fully absorbed, the elastic potential energy stored in the spring 9 begins to be released, pushing the hollow support column 4 and the platform assembly on it upwards, smoothly returning to the initial working height. During this process, the buffer structure 10 ensures that the reset action is smooth and gentle, without producing violent rebounds or vibrations, thus preparing for the next cut.

[0029] After one or more cuts, a certain number of noodle segments will accumulate on the movable platform 2. The control system is then activated, and the motor inside the horizontal support rod 5 drives the connecting column 501 to rotate, causing the movable platform 2 to rotate around the axle, forming an inclined surface. The cut noodle segments then automatically slide down into the pre-set collection container under gravity, achieving efficient and hygienic material feeding. After feeding is complete, the movable platform 2 returns to a horizontal position and begins a new work cycle.

[0030] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
