Description

Technical Field

[0001] This utility model belongs to the field of screening equipment manufacturing technology, specifically relating to an intelligent screen feeding double saw blade saw. Background Technology

[0002] A high-square screen is a common vibrating screening device widely used in grain processing, food, and chemical industries for grading and screening granular materials. Its main working principle is to automatically stratify and separate materials according to particle size through the horizontal circular vibration or reciprocating motion of the screen frame. A high-square screen typically consists of a screen frame, screen mesh, transmission mechanism, and vibration device. It features high screening efficiency, large processing capacity, compact structure, and stable operation, meeting the screening needs of various materials.

[0003] Currently, the production of high-square screen grids still relies on manual table sawing, resulting in low efficiency, poor safety, and difficulty in guaranteeing accuracy. Due to the diverse range of material sizes, each change in material specifications requires manual adjustment of the table saw's limit stops. This adjustment process is cumbersome and time-consuming, and because it relies on manual operation, the adjustment accuracy of the limit stops cannot meet the demands of high-quality production, easily leading to dimensional errors. Furthermore, the processing involves a large number of narrow wooden strips less than 20mm wide, which are extremely dangerous to process, increasing the risk of injury to operators and posing a significant challenge to the company's safety management. From a production management perspective, the entire processing flow lacks coordination, the processing technology is complex, and there is a lack of standardization and automation, affecting production efficiency and product quality consistency. In summary, the existing process is no longer suitable for the high demands of modern production in terms of efficiency, safety, and accuracy, and urgently needs improvement and optimization.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 The present invention provides the following technical solution: an intelligent sieve feeding double saw blade saw, including a frame 1, a cutting beam 2, a feed beam 3, a cutting assembly 4, a plate clamp 5, and a feed drive assembly 6.

[0024] The frame 1 is a rectangular frame structure assembled from multiple high-strength profiles using bolts or welding. It possesses high rigidity and stability to ensure the saw can withstand vibrations and loads generated during cutting. The bottom of the frame is equipped with support feet or anchor bolts to secure the saw's installation position on the ground. Additionally, guide rails or grooves can be installed in certain areas for mounting and securing other components, such as the cutting beam and feed beam, to achieve precise positioning and operation of the overall structure.

[0025] Cutting beam 2 is installed on frame 1. Cutting beam 2 is located on the upper part of frame 1, and its two ends are fixed to both sides of frame 1. Cutting beam 2 and frame together form a gantry-shaped structure, creating a space for cutting wood below.

[0026] The feed beam 3 is configured similarly to the cutting beam 2. The feed beam 3 is mounted on the frame 1 via linear guide rails 7, parallel to the cutting beam 2, while the linear guide rails 7 are perpendicular to the cutting beam 2. The feed beam 3 moves along the linear guide rails 7, thus moving below the cutting beam. Two linear guide rails 7 are symmetrically fixed to the frame 1, and sliders adapted to the linear guide rails are fixed at both ends of the feed beam 3 to enable the feed beam 3 to move horizontally and linearly below the cutting beam 2 in a parallel state.

[0027] The cutting assembly 4 is the core functional component for achieving synchronous cutting with dual saw blades, primarily used for efficient and precise double-sided cutting of sheet metal. Through the parallel arrangement of the two band saw blades within the cutting assembly, it can simultaneously cut both sides of the sheet metal in a single operation, significantly improving processing efficiency and cutting quality. Two cutting assemblies are mounted on the cutting beam, with at least one assembly mounted on the beam via a cutting line module 8 extending along the beam's length. Each cutting assembly includes a cutting shaft with its axis parallel to the cutting beam 2 and saw blades 4-1 mounted on the cutting shaft. In this embodiment, specifically, one of the two cutting assemblies is fixed to one end of the cutting beam, and the other is mounted on the cutting beam via the cutting line module.

[0028] A linear module with horizontal linear drive is an existing automated unit component used to achieve linear motion. It typically consists of a guide rail, a slider, a linear drive unit (such as a ball screw, synchronous belt, or linear motor), and a matching support structure. Powered by the linear drive unit, the slider performs high-precision linear motion along the guide rail. This module features a compact structure, high motion accuracy, and smooth operation, and is widely used in automated equipment for achieving horizontal linear motion in positioning, transmission, or processing operations. The cutting linear module is mounted on the cutting beam. The cutting assembly is mounted on the slider of the cutting linear module as a movable assembly. Please refer to [link to relevant documentation]. Figure 2 The cutting assembly includes a cutting frame 4-2, a cutting motor 4-3 mounted on the cutting frame 4-2, and a saw blade 4-1 mounted on the output shaft of the cutting motor. The cutting linear module 8 serves as the active drive component for adjusting the distance between the two cutting assemblies, changing the cutting width by altering the axial distance between the two cutting assemblies 4.

[0029] The sheet metal clamp 5 is a clamp that secures and holds the sheet metal being cut. Two sheet metal clamps 5 are mounted on the feed beam 3, and at least one of the sheet metal clamps 5 is mounted on the feed beam 3 via a clamping linear module 9 extending along the length of the feed beam 3. (See also...) Figure 3The sheet metal clamp includes a clamping seat 5-1, a clamping cylinder 5-2, and a clamping plate 5-3. The feed drive assembly 6 is connected to the feed beam 3 and drives the feed beam 3 to move along the linear guide rail. In this embodiment, specifically, one of the two sheet metal clamps 5 is fixed to the end of the feed beam 3 and is located on the same side as the fixed cutting assembly. The other of the two sheet metal clamps 5 is mounted on the feed beam 3 via a mounting linear module 9. The mounting linear module 9 is similar to the cutting linear module described above. The clamping seat of the movable sheet metal clamp is fixed to the slider of the mounting linear module by bolts, and the clamping seat of the other fixed sheet metal clamp is fixed to the feed beam. The upper surface of the clamping seat 5-1 is a clamping end face used to clamp the cut plate. A limiting block 5-4 is installed on the outer side of this end face via fasteners to limit the lateral position of the clamped plate. The cylinder body of the clamping cylinder 5-2 is fixed to the clamping seat 5-1. The clamping cylinder 5-2 has an upwardly extending lever, on which a clamping plate 5-3 is mounted. The lower surface of the clamping plate 5-3 is a clamping surface corresponding to the upper surface of the clamping seat 5-1, used to clamp the plate. Furthermore, a notch is provided on the clamping end face of the clamping seat 5-1 to allow for saw blade cutting, preventing interference when the saw blade cuts the plate.

[0030] This includes a material ejector chute, a functional component that receives the cut sheet metal. The material ejector chute is located below the cutting beam and feed beam, and is installed inside the frame in a detachable and replaceable manner as a functional mechanism. Please refer to [link / reference]. Figure 5 The unloading chute includes an unloading bracket 10 and unloading pallets 11 mounted on the unloading bracket. The unloading bracket 10 is located on both sides of the unloading chute and is fixed to the inner side of the frame 1 by bolts. Two unloading pallets 11 are mounted on the unloading bracket 10, and the two unloading pallets 11 are arranged obliquely in a slope-shaped structure. The feed beam 3 can move horizontally and linearly to the front end of different unloading pallets 11 to unload different parts after cutting.

[0031] The cutting assembly 4 is equipped with a pusher component 4-4. The pusher component 4-4 is a frame fixed to the side of the cutting frame of the cutting assembly 4. It forms a downwardly extending part that stops the cut sheet material. The cut sheet material is pushed into the unloading groove by releasing the clamping sheet material clamp and moving it closer.

[0032] The feed drive assembly 6 is the drive unit that moves the feed beam. In order to make the structure of this equipment more compact, and to house only the cutting and feeding functional assemblies on the upper part of the equipment, the assembly position and drive structure of the feed drive assembly have been redesigned. The feed drive assembly is located below the unloading chute, utilizing the space at the bottom of the frame close to the ground.

[0033] The feed drive assembly includes a feed drive frame and a feed linear drive unit. The feed linear drive unit is connected to the feed beam via the feed drive frame 6-1 and drives the feed beam to move. Further, the feed drive frame includes two side frames and a bridge connecting the two side frames. The upper ends of the two side frames are connected to the feed beam, and the bridge connects to the feed linear drive unit. See also... Figure 4 The linear feed drive device includes a feed drive motor 6-2 and a feed transmission belt assembly. The feed transmission belt assembly includes a drive pulley 6-3, a driven pulley 6-4, and a transmission belt 6-5 mounted on the drive pulley 6-3 and driven pulley 6-4. The transmission direction of the transmission belt 6-5 is parallel to the linear guide rail 7. The transmission belt 6-5 is connected to the bridge frame, and the output shaft of the feed drive motor 6-2 is connected to the drive pulley 6-3. A flexible transmission belt drives the feed beam to move horizontally and linearly. The flexible transmission belt operates with low noise and low vibration, effectively reducing the shaking of the feed beam during movement and improving the overall smoothness of operation, thereby improving machining accuracy and surface quality. The manufacturing process of the transmission belt is relatively mature, the material cost is relatively low, the structure is simple, the position design is more reasonable, and it is easy to maintain and replace, thus reducing the overall manufacturing and maintenance costs of the equipment. Combined with the bridge frame and guide rail design, the transmission belt can be easily integrated with other motion mechanisms to meet the complex motion control requirements of multiple degrees of freedom.

[0034] First, position the cutting assembly and the board clamping fixture in the correct position using the linear module. Then, place the raw wood board to be cut on the board clamping fixture. Click the start button, and the clamping cylinder will clamp the raw wood board. Then, the feed drive motor will drive the board clamping fixture to cut the raw wood board through the saw blade of the cutting assembly.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
