Description

Technical Field

[0001] This utility model belongs to the field of plastic granule production, and in particular relates to a nine-grid cutting machine for production. Background Technology

[0002] In the granulation production process, the raw materials are usually melted as a whole and mixed with other materials before granulation. However, small granulators have small feed inlets, and the melting efficiency of large pieces of material is low when they are fed in at one time. Therefore, a cutting device is needed to cut the material. Moreover, the nine-grid type cutter is prone to material blockage during cutting. Therefore, a nine-grid material cutter is needed to solve the problems of material cutting and blockage of the nine-grid material during cutting. Summary of the Invention

[0003] The purpose of this utility model is to provide a nine-grid cutting machine for production, which aims to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, a nine-grid cutting machine for production is provided, characterized by comprising a worktable, cutting grids, a support structure, an adjustment structure, and a mounting plate. The support structure includes an arch frame and a support plate. A cylinder is bolted to the top of the arch frame, and the output end of the cylinder passes through the top of the arch frame and is fixedly connected to the mounting plate. Multiple guide shafts are welded to the top of the mounting plate, and the guide shafts pass upward through the arch frame to guide the mounting plate. Guide blocks are provided on both sides of the mounting plate, and the guide blocks cooperate with guide grooves provided on the inner side of the arch frame columns. A cutting grid is bolted to the bottom of the mounting plate, and a cutting blade is bolted to the bottom of the cutting grid. Multiple ejector grooves are provided inside the cutting grids, and ejector frames are provided inside the ejector grooves. The ejector frames are located within the nine-grid outer grid and have the same nine-grid outer shape, thereby ensuring that the cutting grid moves up and down with the mounting plate and can complete the cutting action according to the extension and retraction of the cylinder.

[0005] Preferably, the unloading rack is provided with multiple sets of pressing rods, and the pressing rods exist in each individual cell of the cutting grid. The unloading groove is provided with multiple sets of support rods, and some of the support rods pass through the mounting frame and are fixedly connected to the bottom of the arch beam. The pressing rods are located at the connection points and corners of the unloading rack body, and their optimal position is the geometric center of the cutting grid, which is the optimal ejection and acceptance point.

[0006] Preferably, the top of the arch frame is bolted with multiple sets of support plates, and the bottom of the support plates is welded to some of the support rods, thereby ensuring that the unloading frame is limited by some of the support rods and is not affected.

[0007] Preferably, the bottom of the mounting plate is provided with a clearance groove that cooperates with the ejector frame and auxiliary structure, thereby ensuring that the ejector frame and auxiliary structure will not obstruct the pressing action when pressing down, and that the pressing rod can push out the material after the cutting grid is reset, and the cutting grid does not hinder the cutting depth after pressing down.

[0008] Preferably, the worktable is provided with multiple sets of sliding grooves, each sliding groove is provided with a lead screw in the same direction and a driven gear is fixedly connected to the tail of the lead screw, the bottom of the arch frame is provided with a sliding block that cooperates with the sliding groove, and the middle of the lead screw is connected to and passes through the sliding block, thereby ensuring that the position of the arch frame can be adjusted according to different processing conditions.

[0009] Preferably, multiple sets of support columns are welded to the bottom of the workbench. The adjustment structure includes a motor, a drive gear, a driven gear, and a transmission chain. Multiple sets of motors are bolted to the bottom of the workbench. The output end of each motor is fixedly connected to a drive gear. A transmission chain exists between the drive gear and the driven gear. If multiple sets of motors are used, servo controllers need to be used to provide feedback to each other. Synchronous rotation can be achieved by having two servo controllers receive the same set of pulse signals, or a PID controller can be used to avoid asynchronous rotation of the lead screw. Alternatively, the operator can modify the structure to use a single motor to simultaneously drive multiple sets of driven gears to achieve synchronous transmission and avoid the problem of asynchronous rotation.

[0010] During the use of this utility model, the material to be cut needs to be placed under the cutting grid. The cylinder of the starting device presses down to drive the cutting blade to cut the material. After the cutting is completed, the material is stuck in the cutting grid and cannot fall down. The cylinder resets upward and the pressing rod enters the cutting grid and pushes out the material to complete the cutting.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention solves the problem of material clogging during cutting and the nine-grid cutting process. After the cutting device completes the cutting, the material stuck in the cutting grid can be automatically pushed out to the worktable by the action of the cylinder retraction and the pressure rod. This avoids the material getting stuck in the cutting grid during operation and affecting the cutting effect. The operator does not need to frequently disassemble and maintain the cutting grid, which greatly saves the work efficiency of the cutting operation. Attached Figure Description
