Description

Technical Field

[0001] This utility model relates to honeycomb paperboard production technology, specifically a high-speed cutting mechanism for honeycomb paper. Background Technology

[0002] Honeycomb paper is made based on the principle of honeycomb structure in nature. It is a new type of environmentally friendly and energy-saving sandwich structure material made by bonding corrugated base paper into countless hollow three-dimensional regular hexagons to form a whole load-bearing component - paper core, and then bonding face paper to both sides of it.

[0003] Traditional honeycomb paper core cutting drive mechanisms use an eccentric shaft to drive a connecting rod, which in turn drives the moving blade holder for cutting. However, as the market demands for larger honeycomb paper core cutting widths increase, the increased machine width (over 2.8 meters) leads to greater rigidity, processing difficulty, and cost for the moving blade holder, making it highly susceptible to deformation under stress. Furthermore, the market demands higher speeds for the honeycomb paper core cutting blades to improve cutting efficiency, and the imbalance of the eccentric shaft results in significant machine vibration. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a high-speed cutting mechanism for honeycomb paper, which ensures that the entire rotating shaft is subjected to uniform force in all directions during rotation, thus solving the vibration caused by the unidirectional eccentric wheel drive linkage.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a high-speed honeycomb paper cutting mechanism, including a machine base, wherein several cutting components are evenly distributed on the machine base, each cutting component includes a support, the support is fixed to the machine base, a motor is fixed to the support, the motor drives a rotating shaft to rotate through a transmission unit, the rotating shaft is rotatably connected to the machine base, the rotating shaft is provided with two eccentric wheels, a rear connecting rod and a front connecting rod are respectively provided on both sides of the rotating shaft, one end of the rear connecting rod is sleeved on one of the eccentric wheels, the other end of the rear connecting rod is hinged to a balance knife holder, one end of the front connecting rod is sleeved on the other eccentric wheel, the other end of the front connecting rod is hinged to a moving knife holder, a slider and a guide rail are provided below both the balance knife holder and the moving knife holder, the guide rail is fixed to the machine base, and the slider is slidably engaged with the guide rail.

[0006] Preferably, the transmission unit includes a belt and two pulleys, the two pulleys being coaxially mounted on the output shaft and the rotating shaft of the motor, respectively, and the belt connecting the two pulleys.

[0007] Preferably, a moving blade is provided above the moving blade holder.

[0008] Preferably, there is a 1mm gap between adjacent moving tool holders and a 0.2-0.4mm gap between two adjacent moving tool holders.

[0009] Preferably, the weight of the balance tool holder is equal to the weight of the moving tool holder.

[0010] In summary, this utility model achieves the following technical effects: The high-speed cutting mechanism for honeycomb paper of this utility model consists of multiple cutting components. The entire moving blade holder is divided into multiple moving blade seats, which reduces the weight of the overall moving blade seat, ensures the rigidity of the moving blade seat, and reduces the processing difficulty. In addition, the addition of a rear connecting rod, an eccentric wheel and a balance blade seat can ensure that the rotating shaft is subjected to uniform force during rotation and solve the vibration caused by a single eccentric wheel driving the connecting rod.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0018] Example 1: like Figure 1-2 As shown, a high-speed honeycomb paper cutting mechanism includes a machine base 1. Several cutting components are evenly distributed on the machine base 1. Each cutting component includes a support 2, which is fixed to the machine base 1. A motor 3 is fixed to the support 2. The motor 3 drives a rotating shaft 6 to rotate via a transmission unit. The rotating shaft 6 is rotatably connected to the machine base 1. The rotating shaft 6 has two eccentric wheels. A rear connecting rod 7 and a front connecting rod 10 are respectively provided on both sides of the rotating shaft. One end of the rear connecting rod 7 is sleeved on one of the eccentric wheels, and the other end is hinged to a balance blade holder 8. One end of the front connecting rod 10 is sleeved on the other eccentric wheel, and the other end is hinged to a moving blade holder 11. A slider and a guide rail 9 are provided below both the balance blade holder 8 and the moving blade holder 11. The guide rail 9 is fixed to the machine base 1, and the slider is slidably engaged with the guide rail 9.

[0019] Motor 3 is a servo motor. The addition of a balance blade holder 8 and a rear connecting rod 7 completely balances the back-and-forth vibration of the entire machine tool 1 caused by the reciprocating cutting of the moving blade. The eccentric shaft can stop at any position, meaning any position is a balanced point with uniform force. Multiple servo motors can fully utilize the inertia of high-speed rotation to maintain the continuous rotation of the entire eccentric shaft, reducing the load and energy consumption of a single motor 3; it also increases the service life of a single motor 3. This reduces the vibration of the entire machine tool 1 caused by high-speed cutting and its impact on other mechanical parts by more than 90%, thus lowering the cutting speed of the moving blade. It can increase the cutting speed to over 1000 cuts per minute, improving the original cutting efficiency by 50%. The segmented moving blade and drive mechanism reduces the weight of the overall moving blade holder 11 and the length of each segment of the moving blade holder 11. Each servo motor 3 is equipped with an encoder, and through encoder communication, it is ensured that each servo motor 3 is at the same angle at any moment, thereby ensuring that each rear connecting rod 7 and front connecting rod 10 are at the same eccentric angle, thus ensuring that the segmented moving blade holder 11 is in the same position. From a dynamic perspective, this is equivalent to a set of blade holders reciprocating back and forth to cut the honeycomb paper.

[0020] The transmission unit includes a belt 5 and two pulleys 4. The two pulleys 4 are coaxially mounted on the output shaft and the rotating shaft 6 of the motor 3, respectively. The belt 5 connects the two pulleys 4.

[0021] A moving blade is provided above the moving blade holder 11.

[0022] There is a 1mm gap between adjacent moving blade holders 11 and a 0.2-0.4mm gap between two adjacent moving blades. During high-speed cutting, and because appropriate gaps are provided between moving blade holders 11 and between moving blades, deformation of moving blade holders 11 and moving blades caused by machine heat can be reduced.

[0023] The weight of the balance tool holder 8 is equal to the weight of the moving tool holder 11.

[0024] Compared to machining a moving tool holder of 3000mm or more, machining a moving tool holder 11 of about 500-700mm greatly reduces the machining cost, machining difficulty, and material requirements. The moving tool holder 11, the balance tool holder 8, the front connecting rod 10, and the rear connecting rod 7 are all made of lightweight and high-strength metal alloys such as aluminum alloy or titanium alloy, which reduces mechanical vibration and motor 3 load.

[0025] The high-speed cutting mechanism for honeycomb paper in this embodiment consists of multiple cutting components. The entire moving blade holder is divided into multiple moving blade seats 11, which reduces the weight of the overall moving blade seat 11, ensures the rigidity of the moving blade seat 11, and reduces the processing difficulty. In addition, the addition of a rear connecting rod 7, an eccentric wheel and a balance blade seat 8 can ensure that the rotating shaft 6 is subjected to uniform force during rotation and solve the vibration caused by a single eccentric wheel driving the front connecting rod 10.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
