Description

Technical Field

[0001] This utility model relates to the field of slicing ... Background Technology

[0002] In the food processing industry, vegetable cutters are widely used, greatly improving the efficiency of food processing. The slicing tube, as the core component of the vegetable cutter, plays a crucial role in achieving the slicing operation. Existing vegetable cutters typically consist of an outlet tube, an inlet tube, and a slicing tube located within the outlet tube. A rocker arm is connected to the rear of the slicing tube via a fixed connector. The working principle is as follows: food enters through the inlet tube, contacts the surface of the slicing tube, and the rocker arm drives the slicing tube to rotate at high speed. The blades cut the food into slices, which then enter the slicing tube and are finally output from the front of the outlet tube. This structural design allows the slicing tube to adapt to a variety of foods, whether it's hard root vegetables like yams and lotus roots, soft leafy vegetables like cabbage and lettuce, or even irregularly shaped foods; with appropriate adjustments, relatively uniform slicing can be achieved.

[0003] However, the current slicing tube has certain structural defects. The protrusion at its front end abuts against the front end of the discharge tube, and sliding friction occurs at this contact point during the rotation of the slicing tube. This not only causes wear on components and shortens the equipment's lifespan, but also causes a degree of jamming during rotation, resulting in uneven slice thickness and uneven food surfaces, thus affecting the quality of food processing and subsequent products. Therefore, it is necessary to improve the existing slicing tube structure to overcome these technical problems. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A slicing scalpel barrel with a sealing rotating ring structure includes a scalpel barrel body. The side of the scalpel barrel body is provided with uniformly distributed cutting windows and cutting blades disposed at the cutting window positions. The rear end of the scalpel barrel body is provided with a connector fixing part. The front end of the scalpel barrel body is fixedly connected to an annular rotating component, and a sealing ring is fixedly sleeved on the annular rotating component. The annular rotating component includes an inner ring body and an outer ring body that rotate and cooperate with each other. The inner ring body is fixedly sleeved on the front end of the scalpel barrel body, and the sealing ring is sleeved on the outer ring body.

[0006] Preferably, a blocking wall extends outward from the front end of the cutter barrel body, and a snap-fit ​​ring is also formed around the front end of the cutter barrel body. The snap-fit ​​ring and the blocking wall are spaced apart, and the annular rotating component is configured to forcibly pass through the snap-fit ​​ring and then be restricted between the snap-fit ​​ring and the blocking wall.

[0007] Preferably, limiting walls are formed on both sides of the inner ring body, the outer ring body abuts against the limiting walls, and the outer ring body is also formed with limiting edges that abut against the limiting walls. The outer ring body and the inner ring body are engaged in sliding contact through the limiting walls and limiting edges.

[0008] Preferably, an internal space is formed between the outer ring body and the inner ring body by a limiting wall, and a ball assembly is provided in the internal space. The ball assembly includes an annular positioning plate and multiple ball bodies. The annular positioning plate has multiple evenly distributed ball through holes. The ball bodies are movably connected in the ball through holes, and the ball bodies protrude through both ends of the ball through holes to abut against the inner ring body and the outer ring body respectively.

[0009] Preferably, a reinforcing portion that engages with the ball bearing body is provided on the opposing surfaces of the inner and outer ring bodies.

[0010] Preferably, the outer surface of the outer ring is a concave arc surface, and the sealing ring abuts against the arc surface.

[0011] Preferably, the connector fixing part includes multiple fixing pieces bent inward along the rear end of the knife barrel body, with the multiple fixing pieces spaced apart.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By employing a ring-shaped rotating component, the inner and outer rings rotate in conjunction with each other. This transformation significantly reduces friction during rotation, minimizes wear between components, extends the service life of the slicing tube and its associated discharge tube, and lowers equipment maintenance costs.

[0014] With the ring-shaped rotating component, the slicing tube rotates more smoothly and will not wobble or shift due to uneven friction at the front contact point. This allows the cutting blade to maintain a stable cutting force and angle when cutting food, effectively avoiding problems such as uneven slice thickness and uneven food surface, greatly improving the quality of food processing and ensuring the consistency of subsequent product quality.

[0015] By installing a sealing ring on the annular rotating component fixedly connected to the front end of the blade barrel, this design enhances the seal between the slicing blade barrel and the discharge barrel. During the cutting process, it prevents food residue, juice, and other foreign objects from entering the connection between the slicing blade barrel and the discharge barrel, avoiding equipment malfunctions caused by the accumulation of foreign objects, and also helps maintain the cleanliness and hygiene of the equipment's interior.

[0023] The components include: a main body 10 for the cutter barrel, a cutting window 11, a cutting blade 12, a connector fixing part 13, a blocking wall 14, a snap ring 15, an annular rotating part 20, an inner ring body 21, an outer ring body 22, a limiting wall 23, a limiting edge 24, an annular positioning piece 25, a ball bearing body 26, a reinforcing part 27, an arc surface 28, and a sealing ring 30. Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1-4 In this embodiment of the present invention, a slicing blade tube with a sealing rotating ring structure includes a blade tube body 10. The side of the blade tube body 10 is provided with uniformly distributed cutting windows 11 and cutting blades 12 disposed at the positions of the cutting windows 11. The rear end of the blade tube body 10 is provided with a connector fixing part 13. The front end of the blade tube body 10 is fixedly connected to an annular rotating component 20, and a sealing ring 30 is fixedly sleeved on the annular rotating component 20. The annular rotating component 20 includes an inner ring body 21 and an outer ring body 22 that rotate and cooperate with each other. The inner ring body 21 is fixedly sleeved on the front end of the blade tube body 10, and the sealing ring 30 is sleeved on the outer ring body 22.

[0026] When the slicing tube with a sealed rotating ring structure is in operation, the food enters from the feed tube and contacts the cutting window 11 on the side of the tube body 10, where the cutting blade 12 is located. A rocker arm connected to the rear connector fixing part 13 rotates, causing the tube body 10 to rotate. At this time, the annular rotating component 20 at the front end of the tube body 10 plays a crucial role. The inner ring 21 and the outer ring 22 rotate in coordination, achieving smooth rotation of the tube body 10 through rolling friction, reducing wobbling and offset caused by traditional sliding friction, and ensuring that the cutting blade 12 can cut the food with stable force and angle. The cut food enters the tube body 10 and is then output from the front end of the discharge tube. During this process, the sealing ring 30, fitted on the outer ring 22, tightly fits the connection between the slicing tube and the discharge tube, preventing food residue, juice, and foreign matter such as moisture and dust from the working environment from entering. Furthermore, the elasticity of the sealing ring 30 helps to press against the inside of the equipment, ensuring stable and reliable rotation of the tube body 10.

[0027] By employing a ring-shaped rotating component 20, the inner ring 21 and the outer ring 22 rotate in conjunction with each other. This transformation greatly reduces friction during rotation, reduces wear between components, extends the service life of the slicing tube and its associated discharge tube, and lowers equipment maintenance costs.

[0028] Furthermore, due to the setting of the annular rotating component 20, the slicing tube rotates more smoothly and will not shake or shift due to uneven friction at the front contact position. This allows the cutting blade 12 to maintain a stable cutting force and angle when cutting food, effectively avoiding problems such as uneven slice thickness and uneven food surface, greatly improving the quality of food processing and ensuring the consistency of subsequent product quality.

[0029] In addition, a sealing ring 30 is fitted on the annular rotating component 20 fixedly connected to the front end of the blade body 10. This design enhances the sealing between the slicing blade tube and the discharge tube. During the cutting process, it can prevent food residue, juice, and other foreign objects from entering the connection between the slicing blade tube and the discharge tube, avoiding equipment failure caused by the accumulation of foreign objects, and also helps to maintain the cleanliness and hygiene of the equipment.

[0030] Please see Figure 3-4The front end of the blade barrel body 10 extends outward with a blocking wall 14, which prevents the annular rotating component 20 from moving excessively along the axial direction after installation, providing a limiting barrier. A retaining ring 15 is also formed around the front end of the blade barrel body 10, spaced apart from the blocking wall 14. The annular rotating component 20 is designed to forcibly pass through the retaining ring 15 and then be confined between the retaining ring 15 and the blocking wall 14. The blade barrel body 10 is made of stainless steel, and the retaining ring 15 is stamped onto the blade barrel body 10. Utilizing the elastic deformation and restoring force of the retaining ring 15, it achieves a tight engagement of the annular rotating component 20, ensuring that it will not loosen or fall off during high-speed rotation. This not only ensures that the annular rotating component 20 can stably perform rolling friction, reduce wear, and improve cutting stability, but also makes the overall structure of the slicing blade barrel more compact, enhancing the reliability and durability of the equipment, reducing the risk of malfunctions caused by loose components, and improving the operating efficiency and service life of the equipment.

[0031] Please see Figure 2-3Limiting walls 23 are formed on both sides of the inner ring 21. The outer ring 22 abuts against the limiting walls 23, and the outer ring 22 also has limiting edges 24 that abut against the limiting walls 23. The outer ring 22 and the inner ring 21 are in sliding contact through the limiting walls 23 and the limiting edges 24. An internal space is formed between the outer ring 22 and the inner ring 21 by the limiting walls 23. A ball assembly is provided in the internal space. The ball assembly includes an annular positioning plate 25 and multiple ball bodies 26. The annular positioning plate 25 has multiple evenly distributed ball through holes. The ball bodies 26 are movably connected in the ball through holes, and the two ends of the ball bodies 26 protrude from the ball through holes to abut against the inner ring 21 and the outer ring 22 respectively. Reinforcing parts 27 that mate with the ball bodies 26 are provided on the opposite surfaces of the inner ring 21 and the outer ring 22. Limiting walls 23 are provided on both sides of the inner ring 21, and the outer ring 22 abuts against the limiting walls 23 through the limiting edge 24, realizing a precise abutment and sliding fit between the two. This provides a stable guide for the rotation of the outer ring 22, prevents axial displacement during rotation, ensures the stability of the annular rotating component 20, and thus improves the overall reliability of the slicing tube. A ball bearing assembly is set in the internal space between the outer ring 22 and the inner ring 21 supported by the limiting walls 23. Multiple ball bearing bodies 26 are evenly distributed through the ball bearing through holes on the annular positioning piece 25, and their ends abut against each other. The inner ring 21 and outer ring 22 further transform sliding friction into rolling friction of the balls, significantly reducing rotational resistance and making the slicing tube rotate more smoothly, effectively reducing energy loss. The inner ring 21 and outer ring 22 are provided with reinforcing parts 27 for mating ball bodies 26, which not only enhances the contact stability between the balls and the rings and improves the load-bearing capacity of the ball assembly, but also disperses the pressure on the balls, avoids local wear, and extends the service life of the ball assembly and the entire annular rotating part 20, thereby improving the performance stability of the slicing tube in long-term use.

[0032] Please see Figure 3The outer surface of the outer ring 22 is a concave arc surface 28, on which the sealing ring 30 abuts. This increases the contact area with the sealing ring 30, allowing it to fit more tightly against the outer ring 22, further enhancing the sealing effect. This effectively prevents the intrusion of food residue, juices, and external dust and other impurities, better maintaining the cleanliness and hygiene of the equipment's interior and meeting the stringent requirements of food processing environments. Simultaneously, compared to a flat surface, the arc surface 28 allows for more even stress distribution on the sealing ring 30 under pressure, reducing deformation or damage caused by localized stress concentration, extending its service life, and lowering maintenance costs associated with frequent replacements. Furthermore, during the rotation of the slicing cylinder body 10, this design helps reduce frictional resistance between the sealing ring 30 and the outer ring 22, resulting in smoother rotation, reduced energy loss, and further improved overall operating efficiency and stability of the slicing cylinder.

[0033] Please see Figure 1 The connector fixing part 13 includes multiple fixing pieces bent inward along the rear end of the blade barrel body 10, with spacing between the fixing pieces. The multiple fixing pieces increase the contact points with the connector, enabling a more secure connection and fixation. This ensures that when the rocker arm drives the blade barrel body 10 to rotate at high speed, the connection between the connector and the blade barrel body 10 remains stable and reliable, preventing easy loosening or detachment. This guarantees the stability of power transmission and, consequently, ensures the efficient and stable operation of the slicing blade barrel.
