Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing equipment technology, specifically a rice and flour processing strip-opening machine. Background Technology
[0002] In the entire process of processing rice and flour products from raw materials to finished products, the strip-cutting process is a crucial link connecting the upstream and downstream processes. Its processing precision and efficiency directly determine the quality and market competitiveness of the final product.
[0003] The existing patent document CN220108991U discloses a rice and flour processing sheet-opening machine. The rice and flour processing sheet-opening machine provided by this utility model has an edge-straightening mechanism. During the rice and flour sheet-opening process, the edge-straightening plate is fixed to the connecting seat through a connecting frame, locking pin, and locking groove. The edge-straightening plate straightens the edges of the dough, which can prevent the rice and flour from extending outwards during the rice and flour sheet-opening process and improve the neatness of the rice and flour sheet-opening process. Through the unloading component, the processed rice and flour can be easily guided to a suitable position, thereby facilitating the unloading of the processed rice and flour.
[0004] However, existing rice and flour processing machines are not suitable for building efficient air-cooling systems. They lack axial flow fans, air ducts, air guides, and nozzles. They cannot draw in air through axial flow fans and distribute it to the air ducts via splitters, nor can they use air guides to direct airflow and increase the contact area and time with the cutting head. Therefore, when the cutting head is cutting rice and flour at high speed, it is difficult to quickly remove the heat generated by friction. The cutting head is prone to overheating, causing the rice and flour to gelatinize and stick together, affecting the sharpness and cutting stability of the cutting head, thereby reducing the efficiency and quality of rice and flour cutting and shortening the service life of the cutting head. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] The purpose of this invention is to provide a rice and flour processing sheet-opening machine to solve the problem mentioned in the background art that the existing rice and flour processing sheet-opening machines are not convenient for building an efficient air-cooling system.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a rice and flour processing slitting machine, comprising a frame, two sets of blade holders horizontally arranged above the frame, each set of blade holders having evenly distributed slitting blades mounted at its bottom end, an axial flow fan installed in the middle of the upper surface of the blade holder, a filter screen provided at the air inlet end of the axial flow fan, and a diversion pipe fixedly connected to the air outlet end of the axial flow fan passing through the blade holder, with air guide pipes connected to both ends of the diversion pipe, the two air guide pipes located on both sides of the slitting blades, and inclined air guide covers provided on both the upper and lower sides of the air guide pipes, with evenly distributed nozzles on the opposite sides of the two air guide pipes, the air outlets of the nozzles facing the cutting edge area of the slitting blades.
[0009] As a further improvement to the above solution, a conveyor belt is provided on the inner side of the frame, the surface of the conveyor belt is provided with anti-slip texture, and a No. 1 gantry frame is erected on the top of the frame.
[0010] As a further improvement to the above solution, a vertical hydraulic cylinder is installed through the middle of the No. 1 portal frame, and an adjusting rod is fixedly connected to the transmission end of the bottom of the hydraulic cylinder. The bottom end of the adjusting rod is connected to an inverted U-shaped mounting bracket.
[0011] As a further improvement to the above solution, a flattening roller is horizontally rotatably connected to the inner side of the inverted U-shaped mounting bracket via a bearing, and the flattening roller is located directly above the conveyor belt.
[0012] As a further improvement to the above solution, two sets of No. 2 portal frames are also mounted on the top of the frame, and an electric push rod is vertically installed through each set of No. 2 portal frames.
[0013] As a further improvement to the above solution, a push rod is fixedly connected to the transmission end at the bottom of the electric push rod, and the corresponding tool holder is horizontally fixed to the bottom end of the push rod.
[0014] As a further improvement to the above scheme, each set of tool holders has a guide rod vertically fixed at a position symmetrical to the push rod on its upper surface, and the top of the guide rod extends through to the second gantry frame above it.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This rice and noodle processing sheet-opening machine constructs a highly efficient air-cooling system by setting up an axial flow fan, air ducts, air guide hoods, and nozzles. The axial flow fan draws in outside air, pressurizes it, and delivers it to the distribution pipe. The distribution pipe then evenly distributes the airflow to the air ducts on both sides. The air guide hoods on the upper and lower sides of the air ducts guide the airflow, causing it to flow at a specific angle, increasing the contact area and contact time between the airflow and the sheet-opening cutter head. Meanwhile, the nozzles on the opposite side of the air ducts concentrate the airflow onto the sheet-opening cutter head. During the high-speed cutting of rice and noodles by the cutter head, the continuous airflow can quickly remove the heat generated by friction, effectively reducing the temperature of the cutter head and preventing the rice and noodles from pasting and sticking due to overheating. This ensures the sharpness and cutting stability of the cutter head, thereby improving the efficiency and quality of rice and noodle sheet opening and extending the service life of the cutter head.
[0017] 2. This rice and noodle processing sheet-opening machine uses a hydraulic cylinder on the No. 1 gantry frame to drive the flattening roller to rise and fall. The distance between the flattening roller and the conveyor belt can be adjusted according to the thickness of the rice and noodles to ensure that the rice and noodles are flattened before being opened. This results in rice and noodles with neat shape and uniform size. The flattening roller is rotatably connected to the inverted U-shaped mounting frame through bearings and can rotate synchronously with the conveyor belt to avoid additional friction damage to the rice and noodles and ensure the integrity of the rice and noodles.
[0018] 3. This rice and flour processing slitting machine uses two sets of electric push rods on the No. 2 gantry frame to drive the corresponding blade holders to rise and fall, providing convenient conditions for the maintenance of the blades and conveyor belt. When maintenance is required, any set of electric push rods can be controlled individually to raise the corresponding blade holder, creating sufficient operating space between the slitting blade and the conveyor belt. The blade can be cleaned, replaced, or ground without disassembling the entire equipment. It also facilitates the inspection and maintenance of the surface and underlying components of the conveyor belt. This independent lifting design avoids the cumbersome process of disassembling the blade holder during the maintenance of traditional equipment, reducing downtime and lowering the difficulty of maintenance. At the same time, while one set of blade holders is being maintained, the other set of blade holders can be flexibly adjusted to continue working according to production needs (such as in scenarios where only a single set of blade holders is needed for processing), thus balancing equipment maintenance and production efficiency.

[0025] 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.
[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a rice and flour processing slitting machine, including a frame 1, two sets of blade holders 2 are horizontally arranged above the frame 1, each set of blade holders 2 is equipped with evenly distributed slitting blades 3 at the bottom end, an axial flow fan 4 is installed in the middle of the upper surface of the blade holder 2, a filter screen is provided at the air inlet end of the axial flow fan 4, and a diversion pipe 5 is fixedly connected to the air outlet end of the bottom end of the axial flow fan 4 through the blade holder 2, and air guide pipes 6 are respectively connected to both ends of the diversion pipe 5. The two air guide pipes 6 are respectively located on both sides of the slitting blades 3, and inclined air guide covers 7 are provided on both the upper and lower sides of the air guide pipes 6. Evenly distributed nozzles 8 are also provided on the opposite side of the two air guide pipes 6, and the air outlet of the nozzles 8 faces the cutting edge area of the slitting blades 3.
[0027] During the opening process, the axial flow fan 4 starts simultaneously. Outside air is first filtered by the filter at the air inlet and then pressurized by the fan. The high-pressure airflow is evenly distributed to the two side air guides 6 through the splitter pipe 5. The inclined air guide shrouds 7 on the upper and lower sides of the air guide 6 guide part of the airflow to the upper and lower surfaces of the cutter head, expanding the airflow coverage. At the same time, the nozzles 8 on the opposite side of the air guide 6 focus the core airflow and spray it onto the opening cutter head 3. The high-speed airflow can not only quickly remove the heat generated by the cutting friction and keep the cutter head temperature stable below 30℃, which is far below the gelatinization critical temperature of rice and flour, but also blow away the fine debris attached to the blade edge in time, avoiding the "sticking" or "dragging" phenomenon caused by debris accumulation, ensuring that the cutter head always maintains its sharpness and the cut rice noodles have smooth edges and precise dimensions.
[0028] A conveyor belt 9 is installed on the inner side of the frame 1. The surface of the conveyor belt 9 is provided with anti-slip texture. A first gantry frame 10 is installed on the top of the frame 1. A vertical hydraulic cylinder 11 is installed through the middle of the first gantry frame 10. An adjusting rod 12 is fixedly connected to the transmission end of the bottom of the hydraulic cylinder 11. An inverted U-shaped mounting bracket 13 is connected to the bottom of the adjusting rod 12. A flattening roller 14 is horizontally rotatably connected to the inner side of the inverted U-shaped mounting bracket 13 through a bearing. The flattening roller 14 is located directly above the conveyor belt 9. Two sets of second gantry frames 15 are also installed on the top of the frame 1. An electric push rod 16 is vertically installed through each set of second gantry frames 15. A push rod 17 is fixedly connected to the transmission end of the bottom of the electric push rod 16. The corresponding tool holder 2 is horizontally fixed to the bottom of the push rod 17. A guide rod 18 is vertically fixed at a position symmetrical to the push rod 17 on the upper surface of each set of tool holders 2. The top of the guide rod 18 extends through to the top of the second gantry frame 15.
[0029] Before operation, the entire machine is fixed in place by the frame 1 to ensure stability during processing. The anti-slip texture on the surface of the conveyor belt 9 significantly enhances the friction between the rice and flour blanks and the belt surface. Even at high speeds, it effectively prevents the blanks from slipping or shifting due to inertia, providing a stable conveying base for subsequent processing. After starting the equipment, the rice and flour blanks to be processed are conveyed at a uniform speed by the conveyor belt 9 to the area below the first gantry frame 10. At this time, the hydraulic cylinder 11 is activated according to the preset thickness parameters of the blanks, and the adjusting rod 12 drives the inverted U-shaped mounting frame 13 and the flattening roller 14 to descend precisely. The flattening roller 14 forms a flexible rotating structure with the mounting frame through bearings. After contacting the blanks, it rotates synchronously with the conveyor belt 9, which prevents damage to the blank surface due to friction and uses uniform pressure to press the blanks to a uniform thickness, providing a flat and uniform processing base for the subsequent slitting process and avoiding damage caused by the blanks. The uneven thickness of the material causes cutting deviations. After flattening, the blank continues to move forward with the conveyor belt 9 and enters the processing area of the two sets of tool holders 2 in sequence. The electric push rods 16 on the two sets of No. 2 portal frames 15 can work independently according to the preset slitting specifications: the push rod 17 drives the corresponding tool holder 2 to descend smoothly, while the guide rod 18 slides precisely along the through hole of the No. 2 portal frame 15 to form a double guide limit, ensuring that there is no lateral deviation during the lifting and lowering of the tool holder 2, so that the slitting cutter head 3 can contact the blank vertically. After a single slitting is completed, the electric push rod 16 drives the tool holder 2 to rise quickly and reset, making room for the next round of blank conveying. If it is necessary to clean or replace a certain set of cutter heads, the electric push rod 16 of the corresponding set can be controlled separately to raise the tool holder 2 of that set to the maintenance height, while the other set of tool holders 2 can continue to work, realizing online maintenance and non-stop production, and significantly improving the continuous operation capability of the equipment.
[0030] Working Principle: Before operation, the equipment is fixed in place by the frame 1 to ensure stability during processing. The anti-slip texture on the surface of the conveyor belt 9 significantly enhances the friction between the rice and flour blanks and the belt surface. Even at high speeds, it effectively prevents the blanks from slipping or shifting due to inertia, providing a stable conveying foundation for subsequent processing. After starting the equipment, the rice and flour blanks to be processed are conveyed at a uniform speed by the conveyor belt 9 to the area below the first gantry frame 10. At this time, the hydraulic cylinder 11 is activated according to the preset thickness parameters of the blanks, and the adjusting rod 12 drives the inverted U-shaped mounting frame 13 and the flattening roller 14 to descend precisely. The flattening roller 14 is connected to the mounting frame 10 by bearings. The frame forms a flexible rotating structure, rotating synchronously with the conveyor belt 9 after contacting the blank. This prevents friction damage to the blank surface and uses uniform pressure to press the blank to a consistent thickness, providing a flat and uniform processing base for subsequent slitting processes. This avoids cutting deviations caused by uneven blank thickness. The flattened blank continues to move forward with the conveyor belt 9, sequentially entering the processing areas of the two sets of tool holders 2. The electric push rods 16 on the two sets of second-type portal frames 15 can work independently according to the preset slitting specifications: by pushing the rod 17, the corresponding tool holder 2 is driven to descend smoothly, while the guide rod 18 slides precisely along the through hole of the second-type portal frame 15, forming a... The double-guided limiting system ensures no lateral deviation during the lifting and lowering of the cutter holder 2, allowing the slitting cutter head 3 to make vertical contact with the workpiece. During the slitting process, the axial flow fan 4 starts simultaneously. Outside air is first filtered through the filter at the air inlet end, and then pressurized by the fan. The high-pressure airflow is evenly distributed to the two side air guide pipes 6 through the splitter pipe 5. The inclined air guide hoods 7 on the upper and lower sides of the air guide pipe 6 guide part of the airflow to the upper and lower surfaces of the cutter head, expanding the airflow coverage. At the same time, the nozzles 8 on the opposite side of the air guide pipe 6 focus the core airflow and spray it onto the slitting cutter head 3. The high-speed airflow can quickly remove the heat generated by cutting friction, keeping the cutter head temperature stable below 30°C. The blade operates at a temperature far below the critical gelatinization temperature of rice and flour, and can promptly blow away fine debris adhering to the blade edge, avoiding "sticking" or "dragging" phenomena caused by debris accumulation. This ensures that the blade head always maintains sharpness, resulting in rice noodles with smooth edges and precise dimensions. After a single cutting operation, the electric push rod 16 drives the blade holder 2 to quickly rise and reset, making room for the next batch of blanks. If a certain set of blades needs to be cleaned or replaced, the electric push rod 16 of the corresponding set can be controlled separately to raise that set of blade holders 2 to the maintenance height, while the other set of blade holders 2 can continue to work. This enables online maintenance and uninterrupted production, significantly improving the continuous operation capability of the equipment.
