Description

Technical Field

[0001] This utility model relates to the field of circular sawing technology, specifically to a circular sawing unloading device. Background Technology

[0002] As a high-efficiency and precision cutting device, the circular saw is widely used for cutting and processing various materials such as metal, wood, plastic, and composite materials. After cutting, the cut material (workpiece) needs to be guided by the guide plate and slide or roll to the collection box, conveyor belt, or basket below for collection, so as to facilitate subsequent processing or transfer.

[0003] The feeding speed of materials on the guide plate is related to the differences in material characteristics and the degree of inclination of the guide plate.

[0004] Differences in material properties lead to uncontrollable sliding speeds: Materials of different shapes (such as long bars, thin sheets, blocks, and irregularly shaped parts) exhibit vastly different movement patterns (sliding or rolling) and frictional resistances on a fixed inclined guide plate. For example, thin metal sheets or plastic sheets tend to experience large-area sliding friction with the guide plate, resulting in slower speeds and potential jamming, while blocky materials roll more easily on the guide plate at higher speeds. Furthermore, the surface roughness, density, coefficient of friction, and interaction forces between different materials and the guide plate material (usually metal) significantly affect the sliding speed. For instance, smooth aluminum alloy profiles or rigid plastics (such as POM and nylon) have low coefficients of friction and slide quickly, while rough-surfaced cast iron, untreated wood (such as pine and oak), or burred steel have high coefficients of friction and slide slowly. Lightweight materials (such as certain foam composites or thin wood panels) may be slowed down due to air resistance or electrostatic adsorption.

[0005] Uncontrolled material speed can cause various problems: if the material slides or rolls down too fast, the high-speed impact with the material already piled up in the collection box or the box itself may cause scratches, dents, chipping, or deformation on the material surface. If the material slides down too slowly, the efficiency is low, and the subsequently cut material may accumulate on the guide plate, causing blockages.

[0006] However, in common circular saw unloading devices, the guide plate is usually fixed, and its tilt angle is set during equipment installation and remains fixed during subsequent use. This cannot solve the problem caused by the uncontrollable downward speed due to differences in material characteristics. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this utility model provides a circular saw unloading device. By rotatably connecting the upper end of the guide plate to the lower edge of the cutting table, and connecting the guard plate to the discharge port adjustment and fixing assembly of the partition plate, the tilt angle of the guide plate can be adjusted. The retaining chain can also decelerate the material, thus coordinating and controlling the material unloading speed to avoid problems caused by speed loss.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a circular saw unloading device, comprising a cutting system, a cutting table, a partition, a guide plate, an adjusting and fixing assembly, and a collection box. The cutting system is mounted on the cutting table. The upper end of the guide plate is rotatably connected to the lower edge of the cutting table. The partition is vertical and fixedly mounted on the ground to isolate the cutting system from the outside. The partition has a discharge port. The guide plate is inclined downward and passes through the discharge port. Protective plates are fixedly mounted on both sides of the upper surface of the guide plate. The protective plates are connected to the left and right end faces of the discharge port through the adjusting and fixing assembly, which can fix the protective plates at different positions on the end face of the discharge port. A support platform is mounted on the side wall of the partition and corresponding to the outside. A collection box is mounted on the support platform. The upper edge of the collection box is lower than the lower end of the guide plate. Multiple retaining chains are evenly arranged on the upper end face of the discharge port. The lower ends of the retaining chains hang down to the upper surface of the retaining plate. Multiple slag outlets are evenly arranged on the guide plate. A slag box is mounted on the side wall of the partition and corresponding to the lower position of the discharge port.

[0009] Preferably, the adjusting and fixing component includes screws, and multiple threaded holes are evenly arranged on the left and right end faces of the discharge port. The guard plate is provided with an elongated opening, and the screw can pass through the elongated opening and be screwed into any one of the threaded holes to fix the guard plate and the partition plate.

[0010] Preferably, a hidden groove is provided on the inner side wall of the guard plate at the position corresponding to the elongated opening, and the screw head can be placed in the hidden groove.

[0011] Preferably, the bottom of the collection box is provided with a slide rail, and the support platform is provided with a slide groove, and the slide rail is slidably connected to the slide groove.

[0012] Preferably, the chute is opened in a direction perpendicular to the material guiding direction of the guide plate.

[0013] This utility model provides a circular saw blanking device, which has the following beneficial effects: 1. This utility model achieves this by rotatably connecting the upper end of the guide plate to the lower edge of the cutting table, and by connecting the adjustment and fixing components of the discharge port of the guard plate and the partition plate, so that the tilt angle of the guide plate can be adjusted, and the retaining chain can also decelerate the material, thus coordinating and controlling the material feeding speed to avoid problems caused by speed loss. 2. The adjusting and fixing component of this utility model includes screws, and threaded holes are evenly provided on both sides of the discharge port. The long opening on the guard plate ensures that the threaded holes can still correspond after the guide plate rotates. The screws pass through the long opening and are screwed into the threaded holes to fix the guard plate and the partition plate. The adjustment method is simple and convenient. 3. In this utility model, the guide plate is evenly provided with slag openings. The slag that is cut and stuck to the material may fall off during rolling or sliding and enter the slag box at the bottom through the slag openings, thus avoiding a large amount of slag entering the collection box and making subsequent cleaning troublesome.

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.

[0017] like Figure 1-3As shown, a circular saw unloading device includes a cutting system 1, a cutting table 2, a partition 6, a guide plate 3, an adjusting and fixing assembly, and a collection box 14. The cutting system 1 is mounted on the cutting table 2. The upper end of the guide plate 3 is rotatably connected to the lower edge of the cutting table 2. The partition 6 is vertically and fixedly mounted on the ground to isolate the cutting system 1 from the outside. The partition 6 has a discharge port 7. The guide plate 3 is inclined downward and passes through the discharge port 7. Protective plates 5 are fixedly mounted on both sides of the upper surface of the guide plate 3. The protective plates 5 are connected to the left and right end faces of the discharge port 7 through the adjusting and fixing assembly. The adjusting and fixing assembly can fix the protective plates 5 at different positions on the end face of the discharge port 7. A support platform 17 is provided on the side wall of the partition 6 and corresponding to the outside. The collection box 14 is mounted on the support platform 17. The upper edge of the collection box 14 is lower than the lower end of the guide plate 3. The discharge port 7... Multiple retaining chains 8 are evenly arranged on the upper surface, with the lower ends of the retaining chains 8 hanging down to the upper surface of the baffle plate. Multiple slag ports 4 are evenly opened on the guide plate 3. A slag box 11 is arranged on the side wall of the partition plate 6 and below the discharge port 7. The adjusting and fixing assembly includes screws 12. Multiple threaded holes 9 are evenly arranged on the left and right end faces of the discharge port 7. An elongated opening 13 is provided on the guard plate 5. The screws 12 can pass through the elongated opening 13 and screw into any one of the threaded holes 9 to fix the guard plate 5 and the partition plate 6. A hidden groove 10 is opened on the inner side wall of the guard plate 5 at the position corresponding to the elongated opening 13. The screw head of the screw 12 can be placed in the hidden groove 10. A slide rail 15 is provided at the bottom of the collection box 14. A sliding groove 16 is opened on the support platform 17. The slide rail 15 and the sliding groove 16 are slidably connected. The opening direction of the sliding groove 16 is perpendicular to the guiding direction of the guide plate 3.

[0018] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-3It is known that the cutting system 1 on the cutting table 2 in this utility model can cut the material and push out the cut material, which is existing technology already in use. Before using this utility model, the tilt angle of the guide plate 3 is adjusted according to the characteristics of the material. This can be adjusted based on the experience of the workers or through pre-production experiments, which can be understood by those skilled in the art. Since the guide plate 3 is rotatably connected to the lower edge of the cutting sleeve, the workers can rotate the guide plate 3 to align the long opening 13 with the corresponding threaded hole 9 at a suitable angle, and fix the guard plate 5 and the partition plate 6 with screws 12. The adjustment method is simple and convenient. After the material falls from the cutting table 2, it lands on the guide plate 3, slides and rolls on the guide plate 3, and hits the retaining chain 8, which decelerates it once. According to physics, the speed has not yet reached its maximum at this time, so it will not damage the material. The retaining chain 8 is movable and will not directly stop the material, but only decelerate it. The decelerated material is close to the end of the guide plate 3 and is also on the outside, so it will not cause blockage. Here, the retaining chain 8 is best used for heavier metal materials for better results. When adjusting the tilt angle of the guide plate 3, the role of the retaining chain 8 can also be taken into account, working together to control the material speed. The material is guided from the guide plate 3 into the collection box 14 for unified collection. The guide plate 3 is evenly provided with slag inlets 4. Debris adhering to the material during cutting may fall off during rolling or sliding and enter the slag box 11 at the bottom through the slag inlets 4, preventing large amounts of slag from entering the collection box 14 and causing subsequent cleaning difficulties. This invention utilizes the rotatable connection between the upper end of the guide plate 3 and the lower edge of the cutting table 2, and the connection between the guard plate 5 and the outlet 7 of the partition plate 6 via an adjusting and fixing assembly, allowing the tilt angle of the guide plate 3 to be adjusted. The retaining chain 8 can also decelerate the material, coordinating and controlling the material feeding speed to avoid problems caused by speed loss.

[0019] The inner side wall of the guard plate 5 is provided with a hidden groove 10 corresponding to the long opening 13. The screw head of the screw 12 can be placed in the hidden groove 10 to prevent the material from hitting the screw 12 and causing damage to it, which would make it difficult to disassemble later.

[0020] The bottom of the box is equipped with a slide rail 15, and the support platform 17 is provided with a slide groove 16. The slide rail 15 and the slide groove 16 are slidably connected to facilitate the installation and removal of the collection box 14. The opening direction of the slide groove 16 is perpendicular to the guiding direction of the guide plate 3, and the impact direction of the material is perpendicular to the sliding direction of the collection box 14, ensuring the stability of the collection box 14.

[0021] 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.
