Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plywood processing equipment, specifically to a plywood trimming machine. Background Technology
[0002] In the production and processing of plywood, edge trimming is a crucial step. Its purpose is to ensure that the edges of the plywood are flat, smooth, and meet specific dimensional standards, so as to meet the application needs of many industries such as furniture manufacturing and building decoration.
[0003] Traditional plywood trimming methods primarily rely on manual operation with simple tools such as hand planes and sandpaper for sanding and finishing. This method has several drawbacks. First, manual trimming is extremely inefficient. For large-scale production tasks, it consumes a significant amount of manpower and time, severely restricting production efficiency and failing to meet the demands of modern industrial high-speed, mass production. Second, the precision of manual trimming is difficult to guarantee. Due to differences in operator skill and proficiency, the quality of the trimmed plywood edges is inconsistent, easily leading to dimensional deviations and uneven surfaces. This affects the overall product quality and the smooth progress of subsequent processing steps, increasing the defect rate and rework costs.
[0004] With technological advancements, semi-automatic or simple trimming equipment has gradually been adopted. However, these devices still have many shortcomings in actual use. For example, the debris collection system of some trimming machines is inadequate, resulting in the inability to effectively collect and treat the large amounts of debris and dust generated during the trimming process. This not only pollutes the working environment and endangers the health of operators, but the accumulation of debris can also interfere with the normal operation of the equipment, such as affecting the smooth operation of transmission components, leading to frequent equipment failures, reducing the equipment's lifespan and reliability, and increasing maintenance costs and downtime. Utility Model Content
[0005] The purpose of this invention is to provide a plywood trimming machine to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A plywood trimming machine includes a conveyor belt, and debris collection components are provided on both sides of the conveyor belt for collecting debris generated during the plywood trimming process.
[0008] The debris collection assembly includes a dust collection hood, a dust collection pipe is fixedly connected to the bottom of the dust collection hood, a vacuum cleaner is fixedly connected to the end of the dust collection pipe away from the dust collection hood, and a push baffle is fixedly connected to the upper surface of the conveyor belt.
[0009] Both ends of the dust hood are fixedly connected to a U-shaped positioning plate, the front of the dust hood is fixedly connected to a dustproof baffle, the inner wall of the U-shaped positioning plate is fixedly connected to a positioning plate to block the brush bristles, the bottom surface of the dustproof baffle is fixedly connected to a baffle to block the brush bristles, and the inner wall of the dust hood is rotatably connected to a polishing roller.
[0010] A further improvement of this utility model is that: a drive motor is fixedly connected to the top of the grinding roller, and there are two sets of dustproof baffles, which are symmetrically distributed on the front of the dust collection cover.
[0011] A further improvement of this utility model is that the positioning plate blocking brush bristles and the baffle blocking brush bristles both overlap with the outer wall of the plywood.
[0012] A further improvement of this utility model is that a support frame is provided below the conveyor belt, and a limiting roller is provided above the conveyor belt. The two ends of the limiting roller are rotatably connected to the upper surface of the support frame through an auxiliary frame. The limiting roller is used to guide and limit the plywood.
[0013] A further improvement of this utility model is that a support roller is rotatably connected to the inner wall of the conveyor belt, and side frames are rotatably connected to both ends of the support roller.
[0014] A further improvement of this utility model is that the outer wall of the vacuum cleaner is fixedly connected to the inner wall of the support frame by a mounting plate.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] This invention provides a plywood trimming machine. During trimming, the grinding roller rotates at high speed driven by a motor, precisely grinding and trimming the edges of the plywood to ensure trimming quality. Simultaneously, after the vacuum cleaner is activated, a negative pressure environment is created inside the vacuum hood. Powerful suction quickly draws in debris generated during the trimming process through the suction pipe, preventing debris accumulation in the work area. This integrated design greatly improves work efficiency, eliminating the need for manual debris removal, saving labor and time costs, and enabling continuous and efficient trimming work. Furthermore, the timely collection of debris effectively prevents it from spreading throughout the workshop, maintaining a clean and hygienic working environment, creating better working conditions for operators, reducing equipment malfunctions and safety hazards caused by debris residue, and ensuring the stability and continuity of production.
[0017] This invention provides a plywood trimming machine, where the coordinated action of the push baffle and the limiting roller provides strong support for stable plywood trimming. The push baffle laterally limits the plywood from both sides, strictly restricting its horizontal displacement and ensuring it moves along a predetermined path. The limiting roller functions longitudinally on the upper surface of the plywood, maintaining stability perpendicular to the conveyor belt's direction of movement through close contact and moderate friction. This effectively prevents the plywood from shifting, swaying, or tilting during trimming, thus ensuring trimming accuracy and consistency and improving product yield. Furthermore, the design of the positioning plate and the baffle baffle is ingenious. Without affecting the normal movement of the plywood, they closely overlap the outer wall of the plywood, gently sweeping away debris from the surface and preventing it from falling back into the working area or being drawn into the equipment during trimming, further improving debris collection efficiency. At the same time, these bristles also play a good role in preventing dust, forming a barrier that effectively prevents the dust generated during the trimming process from spreading to the surrounding environment, reducing air pollution, protecting the health of operators, and meeting the requirements of environmentally friendly production, making the entire trimming process more precise, efficient, environmentally friendly and safe.

[0024] The present invention will be further described in detail below with reference to embodiments: Example
[0025] like Figure 1-4 As shown, this utility model provides a plywood trimming machine, including a conveyor belt 1, with debris collection components on both sides of the conveyor belt 1, which are used to collect debris generated during the plywood trimming process.
[0026] The debris collection assembly includes a dust collection hood 6, a dust collection pipe 7 is fixedly connected to the bottom of the dust collection hood 6, a vacuum cleaner 9 is fixedly connected to the end of the dust collection pipe 7 away from the dust collection hood 6, and a push baffle 2 is fixedly connected to the upper surface of the conveyor belt 1.
[0027] Both ends of the dust hood 6 are fixedly connected to a U-shaped positioning plate 11, the front of the dust hood 6 is fixedly connected to a dustproof baffle 12, the inner wall of the U-shaped positioning plate 11 is fixedly connected to a positioning plate bristle blocking bristle 14, the bottom surface of the dustproof baffle 12 is fixedly connected to a baffle bristle blocking bristle 15, and the inner wall of the dust hood 6 is rotatably connected to a polishing roller 13.
[0028] The top of the grinding roller 13 is fixedly connected to the drive motor 4, and there are two sets of dust baffles 12, which are symmetrically distributed on the front of the dust collection hood 6. Example
[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, both the positioning plate blocking brush bristles 14 and the baffle blocking brush bristles 15 overlap with the outer wall of the plywood.
[0030] A support frame 5 is provided below the conveyor belt 1, and a limit roller 3 is provided above the conveyor belt 1. The two ends of the limit roller 3 are rotatably connected to the upper surface of the support frame 5 through an auxiliary frame. The limit roller 3 is used to guide and limit the plywood.
[0031] The inner wall of the conveyor belt 1 is rotatably connected to a support roller, and the two ends of the support roller are rotatably connected to a side frame 8. The outer wall of the vacuum cleaner 9 is fixedly connected to the inner wall of the support frame 5 through a mounting plate 10.
[0032] The working principle of this plywood trimming machine will be explained in detail below.
[0033] like Figure 1-4 As shown, the plywood is placed between two sets of push baffles 2 on the conveyor belt 1 and limited by the push baffles 2. Then the conveyor belt 1 starts and drives the plywood to move towards the dust hood 6. When the edge of the plywood comes into contact with the grinding roller 13, the grinding roller 13 starts to rotate under the drive of the drive motor 4 and performs edge trimming work on the plywood. At this time, the vacuum cleaner 9 starts.
[0034] During startup, the vacuum cleaner 9 generates negative pressure inside the vacuum hood 6 through the vacuum pipe 7, which in turn draws the debris generated during the plywood trimming process into the vacuum pipe 7.
[0035] During the plywood trimming process, the plywood is pushed forward by the conveyor belt 1. Therefore, the positioning plate blocking the brush bristles 14 and the baffle blocking the brush bristles 15 can ensure that the movement of the plywood is not hindered, while forming a sweeping effect on the debris on the plywood. Moreover, it can prevent dust from spreading into the environment, so that the vacuum cleaner 9 can collect debris and dust to the greatest extent.
[0036] The limiting roller 3 is located on the upper surface of the plywood. Under the limiting action of the limiting roller 3, the plywood can move in a direction parallel to the conveyor belt 1 without deviating, thereby ensuring that the subsequent trimming work of the plywood can be carried out stably.
[0037] The dust cover 6 is fixed to the outer wall of the side frame 8.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
