Description

Technical Field

[0001] The invention relates to the technical field of cutting tools, in particular to a circular internal rotary cutting blade. Background Art

[0002] Traditional circular cutting blades usually use the outer edge of the blade for cutting operations. This cutting method has many problems in practical applications. First, the need to reciprocate the blade feeding and retracting operations leads to low cutting efficiency, especially when dealing with high-toughness flexible products such as meat, tendons, and rubber. Second, the open edge of the blade is prone to cause production safety hazards and increase the risk of operators. In addition, repeated feeding and retracting operations may also lead to unstable product quality and fail to meet high quality requirements.

[0003] In the prior art, although there are some patents for improving cutting efficiency and quality, there are still some shortcomings. For example, Patent No. CN201220328576.3 proposes an improved circular cutting blade. Although it improves the cutting efficiency to a certain extent, it still adopts the traditional outer edge cutting method and fails to fundamentally solve the problems of low cutting efficiency and safety hazards. For another example, Patent No. CN201610522398.7 proposes a new type of cutting device. Although it has a complex structure and high manufacturing cost, its cutting efficiency and product quality still need to be improved when processing flexible products with high toughness. Summary of the invention

[0004] In view of the problems and shortcomings in the prior art, this device proposes a new circular internal rotary cutting blade, which aims to solve the problems of low efficiency, safety hazards and unstable product quality of traditional circular cutting blades when cutting flexible products with high toughness.

[0005] Specifically, the technical solution provided by the present invention is: a circular internal rotary cutting blade, including a blade body, the blade body is composed of a cutting edge, a center hole, and an edge hole. The front end surface of the blade body is processed with a circle of arc-shaped cutting edges, and a center hole is provided at the center position of the cutting edge. The center hole is used to fix the center bearing, and a plurality of edge holes of the same aperture are provided on the front end surface of the blade body around the center hole. The edge holes are used to fix the flange bearing, and the center hole is used to fix the center bearing.

[0006] Furthermore, the cutting blade extends in a spiral shape around the center to the edge of the blade body, and the blade body rotates one circle to slice the cut product from the outside to the inside.

[0007] Furthermore, the edge holes are used to fix the large flange and connect the thin-walled bearing of the flange via gears or pulleys.

[0008] Furthermore, the center hole is used to fix the small flange, and the center bearing matched with the small flange is connected to the large flange through a chain or belt rotation to realize the transmission of the large flange and ensure the stable production of the product during operation.

[0009] Furthermore, the end of the cutting blade is provided with adjustable points A, B and C. The length of the offset distance between points A and B represents the size and thickness of the product being cut; the distance between points B and C represents the height of the effective cutting range, and a blade with a shortened or extended distance between the two points can be produced according to the size of the product being cut.

[0010] Furthermore, the cutting blade is spiral-shaped, and the staggered arrangement of point A and point B is utilized to realize automatic material conveying when the product is cut, thereby eliminating the need for conveying steps.

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0016] Embodiment 1

[0017] like Figure 1As shown, in this embodiment, the circular internal rotary cutting blade includes a blade body 1, and a circle of arc-shaped cutting blade edges 101 are processed on the front end surface of the blade body 1. A center hole 102 is provided at the center position of the cutting blade edge 101 for fixing the center bearing. Around the center hole 102, a plurality of edge holes 103 with the same aperture are provided on the front end surface of the blade body 1 for fixing the flange bearing. The stable rotation of the blade body is achieved through the cooperation of the center bearing and the flange bearing.

[0018] The cutting blade 101 extends to the edge of the blade body 1 in a spiral shape around the center. The blade body 1 rotates once to complete the cutting operation, avoiding the cumbersome steps of reciprocating feeding and retracting of traditional blades, and significantly improving the cutting efficiency. At the same time, the spiral blade design avoids the safety hazards caused by the open edge blade and reduces the risk of operators.

[0019] The edge hole 103 is used to fix the large flange, and the thin-walled bearing of the flange is connected through a gear or a pulley to realize the transmission of the cutter body. The center hole 102 is used to fix the small flange, and the center bearing of the small flange is connected to the large flange through a chain or a belt to ensure stable production of the product during operation. This design is not only simple in structure, but also has low manufacturing cost and a wide range of applications.

[0020] The end of the cutting blade 101 is provided with adjustable point A and point B. The distance between point A and point B represents the size and thickness of the product being cut. By adjusting the positions of point A and point B, the cutting thickness can be precisely controlled to meet the cutting requirements of different products. The distance between point B and point C represents the effective cutting range height. Blades that shorten or lengthen the distance between the two points can be produced according to the size of the product being cut. At the same time, the spiral blade design also realizes the automatic material carrying function when cutting products, eliminating the conveying steps and further improving production efficiency.

[0021] The blade body 1 and the cutting blade edge 101 are made of high-strength, corrosion-resistant materials such as stainless steel or alloy steel to ensure the durability and cutting effect of the blade.

[0022] Embodiment 2

[0023] Based on the first embodiment, Figure 1 As shown, the structural characteristics, functions and connection methods of each component in the device

[0024] (1) Blade 1

[0025] The cutter body 1 is the core component of the device. It is made of high-strength, corrosion-resistant materials such as stainless steel or alloy steel, and is disc-shaped as a whole. Its front end surface is processed with a circle of arc-shaped cutting blade 101. The blade has a unique design and extends to the edge of the cutter body in a spiral shape to achieve an efficient cutting effect. The cutter body 1 serves as the main body of the cutting tool. Through its rotational motion, it drives the cutter blade 101 to cut the target object. The spiral blade design not only improves the cutting efficiency, but also avoids the vibration and noise that may be generated by traditional blades during the cutting process. The cutter body 1 is connected to the transmission system through the center hole 102 and the edge hole 103. The center hole 102 is used to fix the center bearing, and the edge hole 103 is used to fix the flange bearing to achieve stable rotation of the cutter body.

[0026] (2) Cutter blade 101

[0027] The cutter blade 101 is located at the front end of the cutter body 1 and is distributed in a spiral shape. Its shape and angle are carefully designed to ensure a smooth and efficient cutting process. The cutter blade 101 is the direct execution component of the cutting work. Through contact and friction with the target object, it is cut into the desired shape and size. The spiral design makes the cutting process more continuous and smooth, reducing the debris and noise that may be generated during the cutting process. The cutter blade 101 is an integrated design with the cutter body 1, and is made by casting, forging or machining to ensure its structural strength and cutting effect.

[0028] (3) Center hole 102 and edge hole 103

[0029] The center hole 102 is located at the center of the cutter body 1 and is used to fix the center bearing; the edge holes 103 are evenly distributed around the center hole 102 and are used to fix the flange bearing. The center hole 102 and the edge holes 103 together constitute the transmission system of the cutter body, and the stable rotation and cutting operation of the cutter body are achieved by fixing the bearing and connecting the transmission device. The center hole 102 is connected to the transmission shaft through the bearing, and the edge holes 103 are connected to the transmission system such as gears, pulleys, etc. through the flange bearing.

[0030] (4) Center bearing and flange bearing

[0031] The center bearing and flange bearing are both standard parts with high precision and long life. The center bearing is located in the center hole 102, and the flange bearing is connected to the cutter body 1 through the edge hole 103. The center bearing and the flange bearing jointly bear the task of rotating and transmitting the cutter body, ensuring the smooth and efficient cutting process. The center bearing is fixed in the center hole 102 by means of interference fit or set screws, and the flange bearing is fixed on the edge hole 103 by means of bolts or pins.

[0032] Embodiment 3

[0033] Based on the second embodiment, Figure 1 As shown, the working mode of this device is as follows:

[0034] (1) Start the transmission system: First, start the transmission system such as the motor, reducer, etc., and transmit the power to the center bearing and flange bearing through the transmission shaft.

[0035] (2) Rotation of the cutter body: Driven by the transmission system, the center bearing and the flange bearing drive the cutter body 1 to start rotating. Since the cutting edge 101 is distributed in a vortex shape, the cutter body can cut the target object smoothly and continuously during the rotation process.

[0036] (3) Adjust cutting thickness: According to the cutting requirements, the cutting thickness can be controlled by adjusting the positions of point A and point B. The distance between point A and point B represents the size and thickness of the product being cut. By accurately adjusting the positions of these two points, cutting requirements of different thicknesses can be achieved.

[0037] (4) Collecting the cut products: After cutting is completed, the cut products will be automatically discharged from the bottom or side of the cutter body 1 and can be collected and processed by a collecting device.

[0038] (5) Shutdown maintenance: After completing the cutting task, shut down the transmission system and perform necessary cleaning and maintenance work on the cutter body 1 and the transmission system to ensure their long-term stable operation.

[0039] Embodiment 4

[0040] Based on the first embodiment, Figure 1 As shown, the working principle of the device is: the circular internal rotary cutting blade device is based on the rotary cutting principle and combines the vortex-shaped blade design to achieve an efficient, continuous and smooth cutting process.

[0041] In terms of rotary cutting, the device drives the blade body 1 to rotate through a transmission system such as a motor, a reducer, etc. During the rotation process, the cutting blade 101 on the front end of the blade body 1 contacts the target object and generates friction, thereby cutting it into a desired shape and size. The spiral blade design makes the cutting process more continuous and smooth, reducing the vibration and noise that may be generated during the cutting process.

[0042] In terms of the spiral blade design, the spiral design of the cutter blade 101 is a major innovation of the device. This design not only improves the cutting efficiency, but also makes the cutting process more uniform and stable. During the rotation process, the spiral blade can gradually penetrate into the target object to achieve continuous cutting, avoiding the jumping and breaking phenomenon that may occur in the cutting process of traditional blades.

[0043] In terms of adjustable cutting thickness, the device is also designed with adjustable points A and B to control the cutting thickness. The distance between points A and B represents the size and thickness of the product being cut. By adjusting the positions of these two points, the cutting thickness can be accurately controlled to meet the cutting requirements of different products.

[0044] In terms of the transmission system, the transmission system is responsible for transmitting power to the cutter body 1 to rotate it. The transmission system may include components such as a motor, a reducer, and a transmission shaft. The motor provides power, the reducer is used to reduce the speed and increase the torque, and the transmission shaft transmits power to the center bearing and the flange bearing, thereby driving the cutter body to rotate.

[0045] Embodiment 4

[0046] Based on the first embodiment, Figure 1 As shown, the specific implementation of the device:

[0047] (1) Cutting tool body manufacturing: First, according to the design requirements, a high-strength, corrosion-resistant material such as stainless steel or alloy steel is used to manufacture the cutting tool body 1. A circle of arc-shaped cutting blade edges 101 are processed on the front end surface of the cutting tool body, and the cutting blade edges are distributed in a spiral shape and extend to the edge of the cutting tool body.

[0048] (2) Processing of center hole and edge holes: A center hole 102 is processed at the center position of the cutter body 1 for fixing the center bearing. At the same time, multiple edge holes 103 are evenly processed around the center hole 102 on the front end surface of the cutter body for fixing the flange bearing.

[0049] (3) Bearing installation: The center bearing is installed in the center hole 102 and fixed by means of a set screw or other means. Similarly, the flange bearing is installed in the edge hole 103 and fixed by means of a bolt or a pin.

[0050] (4) Transmission system installation: Install the transmission system such as the motor, reducer, etc. to a suitable position, and transmit the power to the center bearing and flange bearing through the transmission shaft. Ensure that the transmission system is stable and reliable and can drive the cutter body 1 to rotate.

[0051] (5) Adjust cutting thickness: According to the cutting requirements, adjust the positions of point A and point B to control the cutting thickness. The distance between these two points can be adjusted to achieve cutting requirements of different thicknesses.

[0052] (6) Cutting operation: Start the transmission system to make the blade body 1 start to rotate. Place the target object under or on the side of the blade body so that it contacts the cutting edge 101. As the blade body rotates, the cutting edge will gradually penetrate into the target object to achieve continuous cutting. After cutting is completed, turn off the transmission system and take out the cut product.
