Abstract
Description
Technical Field
[0001] This utility model relates to the field of sandblasting machine technology, specifically a through-type sandblasting machine. Background Technology
[0002] Traditional sand-washing machines use belt conveyors and buckets to circulate and lift sand. The sand falls from the top to the highest point. After the wax model is coated with adhesive, it is inserted into the sand and fine sand is applied to its surface to form a mold shell.
[0003] A drum sand-filtering machine, disclosed in publication number CN102744197B, is specifically used for investment casting and belongs to the field of casting equipment technology. It includes a frame, drum, hoppers, electrical cabinet, filter tank, vibrating motor, upper screen, vibrating support, lower screen, worm gear reducer, shaft, rollers, shaft support, and dust-collecting cyclone. Its key feature is that a vibrating support is fixed to the upper end of the frame, and a drum is rotatably mounted on the vibrating support. Multiple hoppers are provided on the inner surface of the drum. Two rollers are provided on each side of the drum, and the two rollers are fixed to a shaft. The shaft is mounted on two shaft supports via bearings, and one end of the shaft is connected to the worm gear reducer. An upper screen and a lower screen are provided inside the drum; the upper screen is fixed to the upper end of the vibrating support, and the lower screen is fixed to the lower end of the vibrating support. It can effectively separate slurry lumps and impurities.
[0004] While existing technologies can separate slurry blocks and impurities to a certain extent, the uniformity of spraying is relatively poor. Therefore, we propose a through-type sand spraying machine. Utility Model Content
[0005] The purpose of this utility model is to provide a through-type sandblasting machine to solve the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a through-type sandblasting machine, comprising a frame and a drum, wherein the frame is equipped with an auxiliary support component for auxiliary support of the drum, and the frame is equipped with a drive mechanism for driving the drum to rotate; a stirring component is provided inside the drum, and the frame is equipped with a first drive component for driving the stirring component to rotate; a mounting bracket for fixing products is provided inside the drum; and multiple material support plates are installed at equal intervals on the inner wall of the drum.
[0007] Preferably, the frame is equipped with arc-shaped seats at both ends of the drum, and a stirring assembly is adjustablely installed between the two arc-shaped seats.
[0008] Preferably, the stirring assembly includes two second bearing seats, which are mounted on two arc-shaped seats, and a second rotating shaft is installed between the two second bearing seats. Multiple blades are installed on the second rotating shaft.
[0009] Preferably, two guide rails are installed on the outer side of the roller; the drive mechanism includes a second drive assembly and a first rotating shaft with a main drive wheel that cooperates with the two guide rails. The first rotating shaft is equipped with a first bearing seat on both sides of the main drive wheel. The first bearing seat is mounted on the frame, and the first rotating shaft is driven by the second drive assembly.
[0010] Preferably, the auxiliary support assembly includes a third rotating shaft, which is equipped with two auxiliary wheels that cooperate with two guide rails, and a third bearing seat is installed on both sides of the auxiliary wheels.
[0011] Preferably, the mounting bracket is adjustablely mounted on the crossbeam, and the frame is equipped with auxiliary beams that provide additional support for the mounting bracket.
[0012] Preferably, the fixing plate is equipped with two guide wheels that cooperate with the crossbeam, the fixing plate is equipped with a bracket via a pin, the bracket is equipped with a mounting rod, and the mounting rod is equipped with an auxiliary support wheel that cooperates with the auxiliary beam.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Uniform Sand Spraying. Advantages of the Rotating Structure: The through-feed sand sprayer uses a rotating mechanism (sand trough) to evenly distribute and drop sand, creating a "sand rain" that gently and evenly coats the workpiece surface. The sand particles are less prone to breakage, ensuring that every part of the workpiece surface receives a sufficient and consistent sand cover, improving product quality. Multiple-Circulation Sand Spraying: The through-feed sand sprayer is designed with a multiple-circulation sand spraying process. During the spraying process, some sand falls into the inner side of the circumferentially moving support plate and, under the rotational force of the support plate, sprays the workpiece surface again. This multiple-circulation sand spraying method further ensures the uniformity of the sand spraying, making the sand layer on the workpiece surface more uniform and dense.
[0015] 2. High Efficiency. Rapid Sanding: The rotating structure of the through-feed sander allows for rapid sand lifting and falling, significantly improving sanding efficiency. Compared to traditional sanding methods, the rotary sander can complete the sanding of the same number of workpieces in a shorter time, thus increasing production efficiency. High Degree of Automation: The rotary sander is equipped with an automated control system. This system automates the sanding process, including automatic sand feeding, automatic control of rotation speed and sanding time. Automated operation not only improves production efficiency but also reduces manual intervention, lowering labor intensity and human error.
[0016] 3. High adaptability. Adjustability: The rotation speed, sand spraying angle, and sand flow rate of the through-feed sandblasting machine can be adjusted according to different workpieces and process requirements. This adjustability allows the rotary sandblasting machine to adapt to workpieces of various shapes, sizes, and materials, meeting diverse production needs. Integration with production lines: The design of the through-feed sandblasting machine allows for easy integration and coordination with production lines. It can be automatically connected to other production equipment (such as casting equipment) to form a complete production line. This excellent integration improves the efficiency and coordination of the entire production system, reducing intermediate steps and time waste in the production process.
[0017] 4. Compact Structure: Through-feed sandblasting machines typically employ a compact structural design. Their various components and devices are optimized for layout, resulting in a relatively small overall size. This compact design not only saves space but also facilitates installation, commissioning, and maintenance. Due to its small footprint, rotary sandblasting machines are particularly suitable for use in production environments with limited space. For example, in small factories or workshops where space resources are often scarce, rotary sandblasting machines can achieve efficient sandblasting operations within a confined space.
[0018] 5. Easy to operate: The operation of the through-feed sandblasting machine is relatively simple and easy to master. Operators can become proficient in operating the equipment and performing sandblasting operations after simple training. Simple and easy to use.
[0019] 6. Simple maintenance: The structure is simple, practical, and not easily damaged, making maintenance convenient and economical. Attached Figure Description

The sand particles are not easily broken, and this uniform sandblasting method ensures that every part of the workpiece surface receives sufficient and consistent sand coverage, improving product quality. Multiple-cycle sandblasting: The through-feed sandblasting machine is designed with a multiple-cycle sandblasting process.
