A vegetable cutting mechanism that facilitates blade replacement

Abstract

This patent discloses a cutting mechanism for easy knife replacement, including a housing and a knife holder. Rectangular openings are provided on the top of both the left and right side walls of the housing. A conveyor belt is located inside the housing, with its frame fixedly mounted on the inner side wall. A first motor is fixedly mounted on the outer rear side wall of the housing, and the motor's shaft is connected to the conveyor belt's drive shaft. This patent achieves a one-to-one matching of "knife-knife holder" by disassembling the integrated ring-shaped knife into a combination structure of independent block-shaped knife holders and individual knives (each knife holder corresponds to a single knife). Through a simple connection method of "square block and square groove positioning + internal threaded ring locking," when a single knife is damaged, only the internal threaded ring of the corresponding knife holder needs to be removed to individually remove the knife holder and knife for replacement, without affecting other intact parts, significantly reducing maintenance costs and simplifying disassembly and assembly operations.

Description

Technical Field

[0001] This patent relates to the field of vegetable cutting machine technology, specifically a vegetable cutting mechanism that facilitates the replacement of blades. Background Technology

[0002] Traditional large vegetable cutters typically use an integrated structure of a "ring-shaped blade holder + multiple cutting blades," with all blades fixed to the same ring-shaped blade holder. When a single cutting blade fails, it cannot be removed and replaced individually; the entire ring-shaped blade holder structure must be disassembled and replaced, leading to two key problems:

[0003] High maintenance costs: Undamaged cutters are replaced along with the cutter holder, resulting in waste of parts;

[0004] The operation is cumbersome: the overall blade holder is large and heavy, and the disassembly and assembly process is time-consuming and laborious, affecting the efficiency of cutting vegetables. To address this, we propose a vegetable cutting mechanism that facilitates blade replacement. Utility Model Content

[0005] The purpose of this patent is to provide a cutting mechanism that facilitates the replacement of blades, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this patent provides the following technical solution: a vegetable cutting mechanism that facilitates knife replacement, comprising a housing and a knife holder, wherein rectangular openings are provided on the top of the left and right side walls of the housing, a conveyor belt is provided inside the housing, the frame of the conveyor belt is fixedly installed on the inner side wall of the housing, and a first motor is fixedly installed on the outer rear side wall of the housing, wherein the rotating shaft of the first motor is connected to the drive shaft of the conveyor belt;

[0007] A mounting base is fixedly installed on the inner right side wall of the housing. A second motor is fixedly installed on the top of the mounting base. A rotating rod is fixedly installed on the right end of the rotating shaft of the second motor. The right end of the rotating rod extends through the right side wall of the housing to the outside of the housing. A fixing ring is fixedly installed on the outer side wall of the rotating rod. A cutting tool is fixedly installed on the outer end of the tool holder. The left side of the tool holder is in contact with the right side of the fixing ring. The right side of the outer side wall of the rotating rod is threaded. An internal threaded ring is screwed onto the thread on the right side of the outer side wall of the rotating rod. The left side of the internal threaded ring is tightly in contact with the right side of the tool holder.

[0008] The right side of the fixing ring is provided with a square groove in a circular shape. The number of square grooves matches the number of tool holders. A square block is integrally formed in the middle of the left side of the tool holder, and the square block is inserted into the square groove.

[0009] Preferably, the inner side of the tool holder is provided with an arc-shaped groove, the curvature of which matches the curvature of the outer wall of the rotating rod, and the inner arc surface of the arc-shaped groove is tightly fitted to the outer wall of the rotating rod.

[0010] Preferably, a rubber gasket is provided between the tool holder and the internal threaded ring.

[0011] Preferably, the left and right ends of the conveyor belt are located within the two rectangular openings, respectively.

[0012] Preferably, baffles are provided on both the front and rear sides of the top of the conveyor belt, and the two baffles are symmetrically distributed.

[0013] Preferably, the top of the housing has a strip-shaped hole in the front-rear direction, and a threaded rod is fixedly installed on the top of the baffle. The top of the threaded rod passes through the strip-shaped hole and is screwed with a nut.

[0014] Compared with existing technologies, the beneficial effects of this patent are as follows: This patent achieves a one-to-one matching of "tool-tool holder" by disassembling the integrated ring tool into a combination structure of independent block tool holders and individual tools (each tool holder corresponds to a single tool); through the simple connection method of "square block and square slot positioning + internal threaded ring locking", when a single tool is damaged, only the internal threaded ring of the corresponding tool holder needs to be removed to remove the tool holder and tool separately for replacement, without involving other intact parts, which greatly reduces maintenance costs and simplifies disassembly and assembly operations.

[0020] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a cutting mechanism for easy knife replacement, including a housing 1 and a knife holder 8. The top of the left and right side walls of the housing 1 are provided with rectangular openings 2. The housing 1 is equipped with a conveyor belt 3 inside. The frame of the conveyor belt 3 is fixedly installed on the inner side wall of the housing 1. The outer rear side wall of the housing 1 is fixedly installed with a first motor 4. The rotating shaft of the first motor 4 is connected to the drive shaft of the conveyor belt 3.

[0022] A mounting base is fixedly installed on the inner right side wall of the housing 1. A second motor 5 is fixedly installed on the top of the mounting base. A rotating rod 6 is fixedly installed on the right end of the rotating shaft of the second motor 5. The right end of the rotating rod 6 extends through the right side wall of the housing 1 to the outside of the housing 1. A fixing ring 7 is fixedly installed on the outer side wall of the rotating rod 6. A cutting tool 9 is fixedly installed on the outer end of the tool holder 8. The left side of the tool holder 8 is attached to the right side of the fixing ring 7. The right side of the outer side wall of the rotating rod 6 is threaded. An internal threaded ring 10 is screwed onto the thread on the right side of the outer side wall of the rotating rod 6. The left side of the internal threaded ring 10 is tightly attached to the right side of the tool holder 8.

[0023] Traditional vegetable cutters in large canteens are convenient for cutting large quantities of vegetables such as radishes (strip-shaped vegetables). Existing vegetable cutters of this type have a motor inside, with a ring-shaped blade holder mounted on the motor shaft. Multiple cutters are mounted on the outer wall of the ring-shaped blade holder. However, when one cutter is damaged, the entire blade holder structure needs to be replaced, making it inconvenient to replace just one cutter.

[0024] This device transforms the traditional ring-shaped cutter into an independent block-shaped cutter holder 8, with a cutter 9 installed on each cutter holder 8. Therefore, when one of the cutters 9 is damaged, it is easy to replace the cutter holder 8 and the cutter 9 at that location. This facilitates independent replacement, saves costs, and makes disassembly and assembly simple and convenient.

[0025] The right side of the fixing ring 7 is provided with a square groove 11 in a circular shape. The number of square grooves 11 matches the number of tool holders 8. A square block 12 is integrally formed in the middle of the left side of the tool holder 8, and the square block 12 is inserted into the square groove 11.

[0026] A square block 12 is inserted into a square slot 11 to define the assembly position of the tool holder 8 and the retaining ring 7.

[0027] This easy-to-change-blade vegetable cutting mechanism is designed for batch cutting of strip-shaped vegetables in canteens. The overall dimensions of the machine casing are 1200mm × 500mm × 600mm, with 5mm thick side walls (made of Q235 cold-rolled steel plate). The rectangular opening at the top of the side walls measures 150mm × 80mm, and the front-to-back strip-shaped holes at the top are 800mm long and 12mm wide, ensuring both structural strength and accommodating vegetable feeding, unloading, and baffle adjustment. The internal conveyor belt has a bandwidth of 140mm and an effective transmission length of 900mm, using a food-grade PU conveyor belt with a transmission speed of 0.2-0.5m / s (adjustable). The frame is 300mm from the bottom of the casing, and symmetrical baffles are installed on the front and back sides of the top. A threaded rod at the top of each baffle passes through a strip-shaped hole and is screwed with a nut, allowing adjustment of the baffle position to accommodate vegetables of different thicknesses.

[0028] Specifically, the inner side of the tool holder 8 is provided with an arc-shaped groove 13, the curvature of which matches the curvature of the outer wall of the rotating rod 6, and the inner arc surface of the arc-shaped groove 13 is tightly attached to the outer wall of the rotating rod 6.

[0029] The arc-shaped groove 13 is designed to improve the compatibility of the contact position between the tool holder 8 and the rotating rod 6.

[0030] In the tool assembly, the retaining ring has an outer diameter of 180mm, an inner diameter of 30mm, and a thickness of 20mm. It has six square slots of 25mm×25mm×15mm evenly distributed around its circumference. The tool holder has dimensions of 40mm×30mm×20mm (made of 45# steel, with a hardness of HRC40 after quenching). The left side has an integrally formed square block in the middle (with an interference fit to the square slot, and a clearance of ≤0.1mm). The inner arc groove has an arc that matches the rotation rod and fits tightly against the outer wall of the rotation rod. The tool is mounted on the outer end of the tool holder, and a rubber gasket is placed between the tool holder and the internal threaded ring.

[0031] Specifically, a rubber gasket 14 is provided between the tool holder 8 and the internal threaded ring 10.

[0032] Specifically, the left and right ends of the conveyor belt 3 are located within two rectangular openings 2, respectively.

[0033] The left and right ends of the conveyor belt 3 are located in two rectangular openings 2, which facilitates the insertion of vegetables and the smooth movement of vegetables out of the right rectangular opening 2.

[0034] Specifically, baffles 15 are provided on both the front and rear sides of the top of the conveyor belt 3, and the two baffles 15 are symmetrically distributed.

[0035] The baffle 15 is designed so that the distance between the two baffles 15 is slightly larger than the thickness of the vegetables, which makes it easier to limit the movement path of the vegetables.

[0036] Specifically, the top of the housing 1 has a strip-shaped hole 16 in the front-back direction, and a threaded rod 17 is fixedly installed on the top of the baffle 15. The top of the threaded rod 17 passes through the strip-shaped hole 16 and is screwed with a nut 18.

[0037] Figure 2 In the middle, the positions of the two baffles 15 can be adjusted left and right to adapt to the transmission needs of vegetables of different thicknesses.

[0038] The first motor is a Y90S-4 type three-phase asynchronous motor (power 1.1kW, rated speed 1400r / min, the conveyor belt transmission speed is reduced to 5-12r / min through a reducer) to drive the conveyor belt; the second motor is a Y100L-2 type three-phase asynchronous motor (power 3kW, rated speed 2800r / min, the rotor speed is adjusted to 300-500r / min through a reducer) to drive the rotor to rotate and cut the tool. The overall parameters are matched with the motor model, taking into account cutting efficiency, structural stability and convenient tool replacement.

[0039] Working principle: Figure 1 In the middle, vegetables are inserted through the rectangular opening 2 on the left, and the conveyor belt 3 can move the vegetables to the right and remove them from the rectangular opening 2 on the right, where they are sliced ​​by the rotating blade 9.

[0040] When one of the cutting tools 9 is damaged, the internal threaded ring 10 and the rotating rod 6 can be removed. The tool holder 8 can be moved to the right so that the square block 12 on its left side is disassembled from the square slot 11 of the housing to complete the disassembly. Then, the brand new tool holder 8 and the cutting tool 9 can be reassembled on the rotating rod 6.
