Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a block cutting device. Background Technology

[0002] In numerous fields such as food processing, building materials manufacturing, and industrial parts production, cutting raw materials into regular squares is a fundamental and crucial process. As modern manufacturing demands increasingly higher standards for product standardization, precision, and production efficiency, the quality of square cutting directly impacts subsequent processing, assembly, and product quality. For example, in the food industry, standardized tofu and cheese blocks must maintain consistent dimensions to meet packaging requirements; stone and wood blocks in the building materials sector require precise right-angle perpendicularity to ensure assembly stability; and metal or plastic block parts in industrial manufacturing have stringent requirements for edge length accuracy. Against this backdrop, square cutting devices, as core equipment for achieving automated and high-precision cutting, have become a significant factor restricting industrial upgrading. Developing cutting devices that combine reliability and adaptability has become a focal point of industry demand.

[0003] The prior art patent document CN212497119U discloses an automatic conveying and cutting device for permanent magnet ferrite block cores. This device addresses the technical problems of long loading and unloading times during core cutting, frequent starting and stopping of the spindle for loading, unloading, table return, and manual clamping, as well as low positioning accuracy, making it difficult to effectively guarantee product quality. The proposed automatic conveying and cutting device for permanent magnet ferrite block cores includes a frame, a loading synchronous belt, a loading conveyor belt, and a core cutting component. The loading synchronous belt has a loading end and an unloading end. The loading conveyor belt is located above the loading synchronous belt, and a conveying gap is provided between the loading conveyor belt and the loading synchronous belt for the core to pass through. The core cutting component is located along the length of the loading synchronous belt on the side of the loading conveyor belt away from the loading end. The frame is equipped with a belt lifting adjustment mechanism for adjusting the height of the loading conveyor belt, a grinding head lifting adjustment mechanism for adjusting the height of the core cutting component, and a drive mechanism for driving the loading synchronous belt.

[0004] In existing technologies, some devices are prone to angular deviation problems due to defects in the steering mechanism. For example, the steering angle is fixed by the mechanical structure and is difficult to adjust flexibly according to material specifications, resulting in an actual steering angle that seriously affects product accuracy and increases costs. Utility Model Content

[0005] The purpose of this invention is to provide a block cutting device that aims to solve the problem of angle deviation during the turning process of some devices.

[0006] To achieve the above objectives, this utility model provides a block cutting device.

[0008] The fixing mechanism includes a second cylinder, which is externally fixedly connected to the top of the working platform. A sliding bar is fixedly connected to the driving end of the second cylinder. Two sliding bars are fixedly connected to the top of the working platform, and the outside of the sliding bars is slidably connected to the inside of the sliding bars.

[0009] The motor 2 is externally fixedly connected to a limiting frame, and the limiting frame is externally fixedly connected to the outside of the fixed column.

[0010] The transmission assembly includes a transmission rack, which is fixedly connected to the outside of the transmission frame and slidably connected to the inside of the limiting frame. The inside of the limiting frame is rotatably connected to the outside of the connecting column.

[0011] The connecting column is fixedly connected to a transmission gear, and the outer side of the transmission gear meshes with the outer side of the transmission rack.

[0015] 1. This utility model discloses a block cutting device that uses a motor to drive a transmission linkage to perform circular motion. The circular motion is converted into the reciprocating linear motion of a transmission rack through the cooperation of a slider and a transmission frame. The meshing of the rack and gears enables the rotating plate to rotate intermittently by 90 degrees. The transmission process is continuous and stable, ensuring that the material turns at the same angle each time, avoiding cutting size errors caused by turning deviations. Compared with traditional intermittent mechanisms, it is easier to achieve fine-tuning and standardized control of the turning angle through motor parameter adjustment. At the same time, the parts wear is small and maintenance is simple, effectively improving the verticality accuracy of block cutting and the stability of equipment operation.

[0016] 2. The block cutting device of this utility model uses a cylinder to drive a sliding strip to slide smoothly along the sliding strip. The coordinated action of the rotating linkage pulling the rotating column enables the fixing plate to achieve linear clamping and to adapt to the side shape of the material by fine-tuning the angle. This ensures a tighter and more uniform fit with the material, effectively avoiding the problems of local loosening or excessive compression deformation that are easily caused by traditional rigid fixing. It significantly improves the stability and adaptability of material fixing and provides a reliable clamping foundation for subsequent precise cutting. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1 to 3 A block cutting device includes a working platform 1, which is used to conveniently place the block material to be cut. A support frame 2 is fixedly connected to the top of the working platform 1. The support frame 2 is used to install a cutting adjustment mechanism 3, which provides high-altitude support for the cutting components and ensures structural stability during cutting. The cutting adjustment mechanism 3 is set inside the support frame 2. The cutting adjustment mechanism 3 is used to adjust the position and height of the blade 36 to achieve precise cutting of blocks of different sizes. A fixing mechanism 4 is set on the top of the working platform 1. The fixing mechanism 4 is used to firmly fix the block to be cut on the working platform 1 to prevent displacement during cutting and affect the cutting accuracy. A fixing column 6 is fixedly connected to the outside of the fixing mechanism 4. The fixing column 6 is used to support the intermittent rotation mechanism 5 and provide an installation base point for the rotating plate 56. The intermittent rotation mechanism 5 is set inside the fixing column 6. The intermittent rotation mechanism 5 can drive the block to be cut to rotate intermittently, which is convenient for cutting different sides or angles.

[0025] The intermittent rotation mechanism 5 includes a second motor 51, which drives the transmission link 53 to rotate. The second motor 51 is externally fixedly connected to the inside of the fixed column 6. The drive end of the second motor 51 is fixedly connected to the transmission link 53, which converts the rotational motion of the second motor 51 into the reciprocating motion of the slider, thus transmitting power. A slider is externally fixedly connected to the transmission link 53, and the slider is embedded inside the transmission frame 54, driving the transmission frame 54 to perform reciprocating linear motion. The transmission frame 54 slides on the outside of the slider, and the transmission frame 54 performs reciprocating motion under the drive of the slider, thereby driving the transmission component 55 to move. The transmission component 55 is provided on the outside of the transmission frame 54, and the transmission component 55 transmits power... The linear motion of frame 54 is converted into the rotational motion of connecting column 57, realizing the conversion of motion form. The external fixed connection of transmission component 55 is connecting column 57. The connecting column 57 is used to connect transmission component 55 and rotating plate 56, and transmits rotational motion to rotating plate 56. The external fixed connection of connecting column 57 is rotating plate 56. The rotating plate 56 is used to place the block to be cut and rotates intermittently under the drive of connecting column 57. The external fixed connection of motor 51 is limiting frame 52. The limiting frame 52 guides and limits the movement of transmission frame 54 and transmission rack 551, ensuring the accuracy of the motion trajectory. The external fixed connection of limiting frame 52 is on the outside of fixed column 6.

[0026] The transmission assembly 55 includes a transmission rack 551, which performs linear reciprocating motion under the drive of the transmission frame 54. It transmits power through meshing with the transmission gear 552. The transmission rack 551 is fixedly connected to the outside of the transmission frame 54, and the outside of the transmission rack 551 is slidably connected to the inside of the limiting frame 52. The inside of the limiting frame 52 is rotatably connected to the outside of the connecting column 57. The outside of the connecting column 57 is fixedly connected to the transmission gear 552, which meshes with the transmission rack 551 to convert the linear motion of the transmission rack 551 into its own rotational motion. The outside of the transmission gear 552 is meshed with the outside of the transmission rack 551.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing mechanism 4 includes a second cylinder 41, which drives the sliding bar 42 to move. The second cylinder 41 is externally fixedly connected to the top of the work platform 1. The sliding bar 42 is fixedly connected to the driving end of the second cylinder 41. Under the drive of the second cylinder 41, the sliding bar 42 slides along the sliding bar 44, causing the fixing plate 43 to clamp or loosen the material. Two sliding bars 44 are fixedly connected to the top of the work platform 1. The sliding bars 44 provide guide tracks for the sliding of the sliding bar 42, ensuring the accuracy of the movement direction of the sliding bar 42. The external sliding connection of 44 is inside the sliding bar 42. The external fixed connection of the sliding bar 42 is a fixed plate 43. The fixed plate 43 directly contacts the block to be cut and fixes the material by squeezing. The external rotating connection of the sliding bar 42 is a rotating link 45. The rotating link 45 is used to connect the two sliding bars 42 so that they can move synchronously and ensure that the clamping force of the fixed plates 43 on both sides is uniform. The other end of the rotating link 45 is internally rotatably connected to a rotating column 46. The external rotating connection of the rotating column 46 is externally rotatably connected to the fixed column 6.

[0028] The cutting adjustment mechanism 3 includes a cylinder 31, which drives the support frame 32 to move up and down, adjusting the cutting height of the blade 36. The cylinder 31 is externally fixedly connected to the inside of the support frame 2. The drive end of the cylinder 31 is fixedly connected to the support frame 32. The support frame 32 is used to mount components such as a motor 33, a threaded rod 34, and a sliding block 35, providing a mounting carrier for the cutting components. The motor 33 is externally fixedly connected to the support frame 32, providing power for the rotation of the threaded rod 34 and driving the sliding block 35 to move left and right. A threaded rod 34 is fixedly connected to the drive end of the motor 33. The threaded rod 34 rotates under the drive of the motor 33, and drives the sliding block 35 to slide along the support frame 32 through the threaded transmission. The sliding block 35 is threadedly connected to the outside of the threaded rod 34. The sliding block 35 moves left and right under the drive of the threaded rod 34, driving the blade 36 to adjust the horizontal cutting position. The outside of the sliding block 35 is slidably connected to the inside of the support frame 32. The bottom of the sliding block 35 is fixedly connected to the blade 36. The blade 36 directly contacts the block to be cut and achieves the cutting function through high-speed rotation.

[0029] In this specific embodiment, when fixing the material, the cylinder 41 pushes the sliding strip 42 to slide along the sliding strip 44. The sliding strip 42 drives the fixing plate 43 to move synchronously, and the fixing plate 43 gradually moves closer to the side of the raw material. At the same time, the sliding strip 42 pulls the rotating column 46 through the rotating connecting rod 45, causing it to rotate outside the fixing column 6, which helps the fixing plate 43 to fit more tightly and stably against the side of the material.

[0030] When cutting the material, the threaded rod 34 is driven to rotate by the motor 33. The sliding block 35 outside the threaded rod 34 moves laterally along the inner groove of the support frame 32, which drives the blades 36 to adjust the distance between them. The cylinder 31 inside the support frame 2 pushes the blades 36 to cut the material. After cutting both sides.

[0031] The motor 51 drives the transmission rod 53 to make a circular motion. The slider at the end of the transmission rod 53 slides in the inner groove of the transmission frame 54, forcing the transmission frame 54 to make a reciprocating linear motion along the groove of the limit frame 52. The transmission frame 54 drives the external transmission rack 551 to move back and forth synchronously, converting the linear motion into the rotational motion of the gear. Thus, the transmission gear 552 drives the rotating plate 56 to rotate 90 degrees synchronously through the connecting column 57, so that the material can complete a 90-degree turn with the rotating plate 56.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
