A food slicer

Abstract

A food slicing machine includes a main unit with a power mechanism installed inside. The main unit also has a slicing chamber, and a cover plate is installed over the opening of the slicing chamber. A slicing blade is rotatably mounted on the inner surface of the cover plate and is connected to the power mechanism, which drives the blade to rotate. An inlet is provided on the cover plate, and a guide cylinder is attached to the outer end of the inlet. Food enters the inlet through the guide cylinder and is sliced ​​into pieces by the slicing blade. The advantages of this invention are: because the inlet, guide cylinder, and slicing blade are all integrated into the same detachable cover plate, their relative positions are precisely defined and fixed when the cover plate is manufactured.

Description

Technical Field

[0001] This utility model relates to the technical field of food processing equipment, specifically a food slicer. Background Technology

[0002] Food slicers are commonly used equipment in the food processing industry, widely applied in homes, restaurants, and industrial production. Their main function is to efficiently and evenly slice various ingredients into pieces to meet different cooking or processing needs. As people's demands for food processing efficiency and product quality continue to increase, the design and performance of food slicers are receiving increasing attention.

[0003] Existing food slicing machines typically include basic components such as a main unit, a power mechanism, slicing blades, and a feeding structure. The slicing blades are usually fixed to the main unit, while the food inlet and its connected guide tube are often housed on a removable cover. This design allows users to easily remove the cover, facilitating routine cleaning and maintenance of the machine's interior, particularly the slicing chamber and slicing blades, ensuring food hygiene and safety, and extending the equipment's lifespan.

[0004] However, the aforementioned existing technical solution has a significant technical drawback. Because the cover plate needs frequent disassembly and reinstallation, and in actual use, the fit between the cover plate and the main unit or slicing chamber often has a certain gap or becomes loose due to wear over long-term use, the cover plate is not completely fixed after installation; it may experience slight shaking or positional shift. Since the feed inlet and guide tube are located on the cover plate, while the slicing blade is fixed to the main unit, this mobility of the cover plate directly results in an unstable relative angle between the central axis of the feed inlet and guide tube and the working surface of the slicing blade.

[0005] This unstable angular relationship severely impacts slicing accuracy. When food enters the slicing area through the feed tube, the slight change in the feed angle alters the contact point and stress between the food and the slicing blade, making stable and precise cutting impossible. This results in uneven slice thickness, irregular shapes, and even problems like food jamming or slice breakage. Poor slicing accuracy not only affects the appearance of the food and reduces its commercial value but also leads to food waste, significantly impacting user experience and work efficiency. Therefore, there is an urgent need for a new type of food slicer that can effectively solve the problem of unstable slicing accuracy caused by frequent cover plate removal while maintaining the advantages of easy cleaning and maintenance. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a food slicing machine with a simple structure, low manufacturing cost, and high slicing precision.

[0007] The purpose of this utility model is achieved by the following method: a food slicing machine, which includes a main unit, a power mechanism installed inside the main unit, a slicing cavity provided on the main unit, a cover plate installed at the opening of the slicing cavity, a slicing blade rotatably installed on the inner surface of the cover plate, the slicing blade being connected to the power mechanism, and the power mechanism driving the slicing blade to rotate. The cover plate has an inlet, and a guide tube is connected to the outer end of the inlet. The food enters the inlet through the guide tube, is cut into slices by the slicing blade, and is discharged through the outlet at the bottom of the slicing chamber.

[0008] Furthermore, a blade shaft seat is installed on the cover plate, and the slicing blade is mounted on the blade shaft seat.

[0009] Furthermore, the inner end of the cutter shaft seat is provided with a docking hole, and correspondingly, the power mechanism is provided with a docking shaft. After the cover plate is installed, the docking shaft is inserted into the docking hole and coaxially connected with it.

[0010] Furthermore: the slicing blade is mounted on the blade disc, and the blade disc is connected to the blade shaft seat.

[0011] Furthermore, the guide cylinder is cylindrical, and the angle A between its central axis and the perpendicular line from the end face of the cover plate is set to be 25° to 40°.

[0012] Furthermore, the slicing cavity is provided with several positioning posts, and correspondingly, the cover plate is provided with several positioning holes. When the cover plate is installed, the positioning posts are inserted into the positioning holes and align with them.

[0013] Furthermore, the host is equipped with several quick-release buckles. After the cover plate is installed, the quick-release buckles are hooked onto the cover plate to fix the cover plate to the slicing cavity.

[0014] Furthermore, the power mechanism is an electric motor.

[0015] Furthermore: the cutter shaft seat includes a bearing seat fixedly mounted on the cover plate, a main shaft is rotatably mounted inside the bearing seat, and a coupling is provided on the cutter disc to connect with the main shaft.

[0016] Furthermore, the main shaft is mounted in a bearing housing via a first bearing and a second bearing, and sealing rings are installed at both ends of the first bearing and the second bearing.

[0017] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0018] 2. In this application, the slicing blade is directly mounted on the cover plate. Since the feed inlet, guide tube, and slicing blade are all integrated into the same detachable cover plate, their relative positions are precisely defined and fixed when the cover plate is manufactured. Regardless of how the cover plate is removed or installed, as long as it is correctly installed over the opening of the slicing chamber, the spatial geometric relationship between the slicing blade and the feed inlet remains unchanged. This fundamentally eliminates the instability of the slicing angle caused by cover plate movement or positional shift, thereby ensuring high precision and stability in food cutting, resulting in slices of uniform thickness and regular shape.

[0019] 3. Stable slicing precision allows for efficient and smooth cutting of ingredients, reducing jamming, repeated cutting, and waste, thereby improving overall processing efficiency. Simultaneously, uniform slicing avoids food waste caused by uneven thickness, increasing ingredient utilization.

[0020] 4. Precise and uniform slicing not only enhances the sensory quality and commercial value of food, but also greatly improves the user experience. Users do not need to worry about machine instability affecting the final slicing quality.

[0021] 5. Although this invention integrates the slicing blade into the cover plate to solve the accuracy problem, the cover plate still retains its detachable feature. This ensures that the internal parts of the equipment, especially the slicing chamber and the slicing blade, are still very convenient to clean and maintain, meeting the high hygiene requirements of food processing equipment, without sacrificing slicing accuracy at the expense of ease of cleaning.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. A food slicing machine includes a main unit 1, a power mechanism 2 installed inside the main unit 1, a slicing cavity 3 provided on the main unit 1, and a discharge port 31 provided at the bottom of the slicing cavity 3; a cover plate 4 is installed to cover the opening of the slicing cavity 3, and a slicing blade 5 is rotatably mounted on the inner surface of the cover plate 4. The slicing blade 5 is connected to the power mechanism 2, and the power mechanism 2 drives the slicing blade 5 to rotate. The cover plate 4 has an inlet 41, and a guide cylinder 6 is connected to the outer end of the inlet 41. The food enters the inlet 41 through the guide cylinder 6, is cut into slices by the slicing knife 5, and is discharged through the outlet 31.

[0029] In this embodiment, the power mechanism is installed inside the main unit 1 and coupled to the slicing blade 5 via a connecting structure. When the machine is started, the power mechanism 2 drives the slicing blade 5 to rotate at high speed. The food to be cut enters the slicing chamber 3 through the guide cylinder 6 and the inlet 41. Under the rotation of the slicing blade 5, the food is cut into slices. The cut food slices are then discharged through the outlet 31 at the bottom of the slicing chamber 3. The core innovation and technical advantage of this application lies in the fact that the slicing blade 5 is rotatably mounted on the inner surface of the detachable cover plate 4, and the inlet 41 and the guide cylinder 6 are also located on the cover plate 4.

[0030] In existing technologies, the slicing blade is typically fixed to the main unit, while the feeding structure is on a removable cover plate. Because the cover plate may experience slight displacement or wobbling during disassembly and installation, the relative angle between the feeding port and the fixed slicing blade becomes unstable, affecting slicing accuracy. This invention integrates and fixes the three key components closely related to the cutting angle—the slicing blade 5, the feeding port 41, and the guide cylinder 6—onto a single cover plate 4. This ensures that once the cover plate 4 is manufactured, the spatial relative positions of the slicing blade, the feeding port, and the guide cylinder are precise and fixed, and will not change due to the disassembly or installation of the cover plate. Regardless of how the cover plate is installed or removed, as long as the cover plate 4 is correctly positioned, the geometric relationship between the three remains constant. This fundamentally eliminates the instability of the slicing angle caused by the movement of the cover plate, greatly improving the accuracy and stability of the slicer and ensuring the uniformity and consistency of the sliced ​​food.

[0031] In one embodiment: a blade shaft seat 7 is mounted on the cover plate 4, and the slicing blade 5 is mounted on the blade shaft seat 7.

[0032] In this embodiment, the blade shaft holder 7 serves as the load-bearing and support structure for the slicing blade 5, and is pre-fixed to the cover plate 4. The slicing blade 5 is precisely mounted on the blade shaft holder 7. The blade shaft holder provides a stable and rotatable axis for the slicing blade, ensuring stable operation of the slicing blade at high speeds, reducing shaking and vibration, and further guaranteeing slicing accuracy. Simultaneously, by using the blade shaft holder 7 as an intermediate connector, the installation process of the slicing blade can be standardized, making the assembly, replacement, or maintenance of the slicing blade more convenient.

[0033] In one embodiment: the inner end of the cutter shaft seat 7 is provided with a docking hole 71, and correspondingly, the power mechanism 2 is provided with a docking shaft 21. After the cover plate 4 is installed, the docking shaft 21 is inserted into the docking hole 71 and coaxially connected with it.

[0034] In this embodiment, the output end of the power mechanism 2 has a mating shaft 21, and the inner end of the blade shaft seat 7 is provided with a mating hole 71 that matches the mating shaft 21. When the cover plate 4 is installed on the main unit 1, the mating shaft 21 of the power mechanism 2 automatically inserts into the mating hole 71 of the blade shaft seat 7, forming a coaxial connection, thereby realizing the power mechanism's drive of the slicing blade. This shaft-hole mating connection method ensures the coaxiality of power transmission, minimizes power loss and radial runout that may occur during transmission, thereby improving the smoothness and accuracy of the slicing blade rotation.

[0035] In addition, this plug-and-play connection method makes the installation and removal of the cover plate extremely simple and quick, further improving the convenience for users to clean and maintain it.

[0036] In one embodiment: the slicing blade 5 is mounted on the blade disc 51, which is connected to the blade shaft seat 7.

[0037] In this embodiment: the slicing blade 5 is first fixed to the blade disc 51, and then the entire blade disc 51 is connected to the blade shaft seat 7. This makes the slicing blade actually indirectly mounted on the blade shaft seat through the blade disc.

[0038] The blade head 51 provides a larger and more stable mounting platform for the slicing blade 5, increasing the overall rigidity and stability of the cutting unit and reducing blade deformation or vibration under high-speed rotation and cutting stress, thus further improving slicing quality. Simultaneously, the blade head structure makes it possible to install multiple slicing blades or combinations of blades with different shapes and functions, improving the versatility and adaptability of the slicer. Furthermore, the blade head 51, along with the slicing blade 5, can be disassembled and replaced as a single unit, simplifying maintenance.

[0039] In one embodiment, the guide cylinder 6 is cylindrical, with its central axis forming an angle A of 25° to 40° with the perpendicular line from the end face of the cover plate 4. This angle determines the posture of the food entering the slicing blade area. Through extensive experimentation and experience, this specific angle range of 25° to 40° has been optimized. At this angle, the food can be guided to the slicing blade in the best posture, resulting in minimal resistance during slicing, the smoothest cut surface, and the most uniform slices. This helps prevent the food from flipping, being squeezed, or getting stuck during cutting, improving slicing efficiency and product quality. Simultaneously, the optimized feed angle reduces secondary damage to the food, lowering the breakage rate and wastage.

[0040] In one embodiment, the slicing cavity 3 is provided with a plurality of positioning posts 32, and correspondingly, the cover plate 4 is provided with a plurality of positioning holes 42. When the cover plate 4 is installed, the positioning posts 32 are inserted into the positioning holes 42 and align with them. When installing the cover plate 4, the user only needs to align the positioning posts 32 and insert them into the positioning holes 42 to achieve quick and accurate alignment of the cover plate 4. This positioning structure ensures that the cover plate 4 can accurately return to the preset position each time it is installed, eliminating installation errors. At the same time, the precise positioning ensures that the slicing blade, feed port and guide tube integrated on the cover plate 4 form a precise fit with the power mechanism and slicing cavity on the main unit 1, thereby continuously maintaining a high-precision slicing effect.

[0041] In one embodiment: the host 1 is provided with a plurality of quick-release buckles 8. After the cover plate 4 is installed, the quick-release buckles 8 are hooked onto the cover plate 4, and the cover plate 4 is fixed on the slicing cavity 3.

[0042] Once the cover plate 4 is placed and positioned at the opening of the slicing chamber 3, the operator simply needs to fasten the quick-release buckle 8 onto the cover plate 4 to securely fix it to the slicing chamber 3 of the main unit 1. The quick-release buckle 8 firmly locks the cover plate 4, preventing it from loosening or falling off due to vibration or accidental impact during the operation of the slicer, thus ensuring the stability of the equipment operation and the safety of the operator. At the same time, the "quick-release" feature allows users to quickly lock and unlock the cover plate, ensuring its fixation strength while allowing for rapid disassembly for cleaning and maintenance, further improving user experience and work efficiency.

[0043] In one embodiment, the power mechanism 2 is an electric motor. The electric motor is directly connected to the cutter head, or connected to the cutter head through a reducer.

[0044] In one embodiment: the cutter shaft seat 7 includes a bearing seat 74 fixedly mounted on the cover plate 4, a main shaft 75 is rotatably mounted inside the bearing seat 74, and a coupling 76 is provided on the cutter disc 51 to connect with the main shaft.

[0045] In one embodiment, the spindle 75 is mounted within a bearing housing 74 via a first bearing 77 and a second bearing 78, with sealing rings 79 installed at both ends of the first bearing 77 and the second bearing 78. This dual-bearing design effectively ensures the concentricity between the spindle and the bearing housing, while also providing better support for the spindle, extending its service life and impact resistance. The sealing rings prevent moisture and other foreign matter from entering the bearings during operation, ensuring a clean and hygienic working environment.

[0046] In summary, the core innovation of the food slicing machine proposed in this utility model lies in the ingenious integration and fixation of the slicing blade 5, the feed inlet 41, and the guide cylinder 6 onto the same detachable cover plate 4.

[0047] The specific working principle is as follows: The main unit 1 contains a motor that provides power. When the machine is started, the motor's connecting shaft 21 inserts into the connecting hole 71 of the blade shaft seat 7 on the cover plate 4, thereby driving the blade shaft seat 7 to rotate. The slicing blade 5 is stably mounted on the blade shaft seat 7 via the blade disc 51, thus the slicing blade 5 also rotates at high speed. The food to be sliced ​​enters the slicing chamber 3 through the cylindrical guide tube 6 and the inlet 41. The central axis of the guide tube 6 forms an optimized angle of 25° to 40° with the perpendicular line to the end face of the cover plate 4, ensuring that the food is delivered to the rotating slicing blade 5 in the best possible position for cutting. After the food is sliced ​​into uniform pieces by the slicing blade 5, it is discharged through the outlet 31 at the bottom of the slicing chamber 3.

[0048] To ensure the stability and precision of the entire cutting process, the cover plate 4 is precisely aligned during installation by the positioning pin 32 on the slicing cavity 3 and the positioning hole 42 on the cover plate 4. Then, the cover plate 4 is firmly fixed to the opening of the slicing cavity 3 by the quick-release buckle 8 on the main unit 1.

[0049] The main technical advantages are as follows: This design, which integrates the slicing blade and the feeding structure into a single unit and fixes it to a detachable cover plate, fundamentally solves the problem in existing technologies where frequent cover plate removal leads to unstable relative positions between the feeding port and the slicing blade, thus affecting slicing accuracy. Regardless of how the cover plate is removed and reinstalled, the relative geometric relationship between the blade, the feeding port, and the guide cylinder remains precisely fixed, ensuring high precision and stability in food cutting, resulting in slices of uniform thickness and regular shape. At the same time, this design retains the feature of quick cover plate removal, ensuring ease of machine cleaning and maintenance, thus achieving a perfect balance between precision, efficiency, and user experience, and therefore can be widely adopted.
