Description

Technical Field

[0001] This utility model belongs to the technical field of sandblasting equipment, and specifically relates to a sandblasting and polishing device. Background Technology

[0002] Sandblasting and polishing technology is widely used in metal processing, surface cleaning, and precision component manufacturing. It uses a high-speed jet of a mixture of abrasive and liquid to impact the workpiece surface, achieving cleaning, polishing, or roughening. However, existing sandblasting and polishing equipment still has significant shortcomings in waste liquid and waste material collection, specifically manifested in the following technical pain points:

[0003] Traditional collection systems typically use fixed waste tanks. During sandblasting, the mixture of waste liquid and solid particles falls directly into the tank. Due to the lack of an active cleaning mechanism, abrasive residues and metal shavings easily adhere to the inner wall of the tank, accumulating over time and forming caking, leading to blockage of the waste discharge channel. Furthermore, the waste discharge port is mostly controlled by manual valves, requiring frequent shutdowns for cleaning, severely impacting operational continuity. In existing technologies, waste liquid discharge and tank cleaning often rely on step-by-step operations: first, the waste discharge port must be opened to drain the waste liquid, and then the adhering substances on the inner wall must be scraped manually or by an independent drive device. This process not only increases the risk of contamination but also... The costs of manual intervention are compounded by the secondary deposition of waste due to operational intervals, making it difficult to guarantee the cleaning effect. Some equipment attempts to introduce electric scrapers, but lacks a linkage design with the waste discharge port, making it impossible to achieve simultaneous scraping and waste discharge. Most collection devices use simple baffles or butterfly valves to seal the waste discharge port, which are prone to gaps due to abrasive wear or liquid corrosion after long-term use, leading to waste liquid leakage. At the same time, the rigid pipe connection between the waste discharge channel and the external collection equipment lacks buffering and is prone to loosening under vibration, further aggravating the leakage problem, polluting the working environment, and increasing subsequent treatment costs.

[0025] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0026] A sandblasting and polishing apparatus, comprising,

[0027] Workbox 1;

[0028] A collection assembly is located on the inner wall of the work box 1. The collection assembly includes a movable shell 2, a sliding sleeve 201, a collection shell 6, a waste discharge port 601, a storage shell 7, a return spring 8, a baffle plate 9, a cleaning blade 10, a support rod 11, and a slide rail 12. The sliding sleeve 201 is fixedly installed on both sides of the bottom of the outer wall of the movable shell 2. The sliding sleeve 201 is slidably fitted onto the top of the outer wall of the slide rail 12. The slide rail 12 is fixedly installed on both sides of the bottom of the inner wall of the work box 1. The collection shell 6 is embedded in the inner wall of the work box 1. The waste discharge port 601 is open... Located at the bottom of the inner wall of the collection shell 6, the storage shell 7 is fixedly set at the center of one side of the inner wall of the working box 1. The baffle plate 9 is slidably embedded in the inner wall of the storage shell 7. One end of the return spring 8 is fixedly set at one side of the outer wall of the baffle plate 9, and the other end of the return spring 8 is fixedly set in the inner wall of the storage shell 7. The cleaning blade 10 is slidably embedded in the inner wall of the collection shell 6. The support rod 11 is fixedly set in the outer wall of the cleaning blade 10. The support rod 11 and the baffle plate 9 are matched with each other. The baffle plate 9 and the waste discharge port 601 are matched with each other.

[0029] In a specific embodiment of this utility model, the collection shell 6 is used to collect the waste liquid generated by sandblasting. The waste outlet 601 is blocked by the baffle plate 9. The cleaning blade 10 scrapes the deposits on the inner wall of the collection shell 6. The support rod 11 squeezes the baffle plate 9, so that the waste liquid is transported to the waste outlet 601 through the cleaning blade 10. The cleaning blade 10, the support rod 11, and the baffle plate 9 form a mechanical linkage. When the cleaning motor 3 drives the lead screw 301 to move the cleaning blade 10, the support rod 11 simultaneously squeezes the baffle plate 9, so that the waste outlet 601 opens automatically. This process realizes the synchronous operation of scraping the deposits and discharging the waste liquid, reducing manual intervention. After cleaning is completed, the return spring 8 pushes the baffle plate 9 to reset and close the waste outlet 601, preventing the waste liquid from flowing back or external pollutants from entering, and ensuring sealing.

[0030] Specifically, the inner walls of the work box 1 are fixedly provided with limiting shells 4 on both sides, and the cleaning blade 10 is slidably embedded in the inner wall of the limiting shells 4.

[0031] In a specific embodiment of this utility model, the cleaning blade 10 is slidably embedded in the inner wall of the limiting shell 4, which can ensure its stable movement accuracy.

[0032] Specifically, cleaning motors 3 are fixedly installed on both sides of the outer wall of the work box 1, and lead screws 301 are fixedly installed at the output end of the cleaning motors 3. One end of the lead screw 301 is threaded to the opening of the cleaning blade 10.

[0033] In a specific embodiment of this utility model, one end of the lead screw 301 is threaded to the opening of the cleaning blade 10, which can ensure its stable drive.

[0034] Specifically, a chuck 5 is fixedly installed at the center of one side of the outer wall of the movable shell 2 via a bracket.

[0035] In a specific embodiment of this utility model, the chuck 5 can ensure the engagement of the parts.

[0036] Specifically, an observation window 101 is embedded in the opening on one side of the outer wall of the work box 1, and an operation port 102 is opened on the top of the outer wall of the work box 1.

[0037] In a specific embodiment of this utility model, an operation port 102 is provided on the top of the outer wall of the work box 1, which can facilitate the installation of the pipes and nozzles required for sandblasting.

[0038] Specifically, the collection shell 6 is connected to an external waste liquid collection device via a hose.

[0039] In a specific embodiment of this utility model, the collection shell 6 is connected to an external waste liquid collection device via a flexible hose, which can ensure cleanliness.

[0040] Working principle:

[0041] In sandblasting, the workpiece is fixed to the movable housing 2 by chuck 5. The external sandblasting equipment is connected to the nozzle through the operation port 102, and a mixture of abrasive particles (including abrasive grains and liquid) is sprayed at high speed onto the surface of the workpiece to complete surface polishing or cleaning. Waste liquid is temporarily stored. The waste liquid and detached impurities generated by sandblasting fall directly into the collection housing 6 embedded in the inner wall of the work box 1. The bottom of the collection housing 6 is designed with a waste discharge port 601, which is initially closed by the baffle plate 9 to prevent waste liquid leakage. The cleaning blade 10 is linked to the scraping and the waste discharge port 601 to trigger cleaning. When the sandblasting operation is completed or the waste liquid in the collection housing 6 reaches the required level, the cleaning is completed. When a certain quantity is reached, the cleaning motors 3 on both sides of the working box 1 are started, driving the lead screw 301 to rotate. The blade scrapes, and the rotation of the lead screw 301 pushes the cleaning blade 10 to slide along the inner wall of the limiting shell 4 through thread transmission. The cleaning blade 10 moves close to the inner wall of the collection shell 6, scraping off the solid waste (such as abrasive residue and metal shavings) attached to the wall surface. The waste discharge port 601 opens. When the cleaning blade 10 moves, the support rod 11 fixed on its outer wall moves synchronously towards the receiving shell 7. The support rod 11 contacts and presses the blocking plate 9, overcoming the elastic force of the return spring 8, and pushes the blocking plate 9 from the... The waste outlet 601 is retracted, automatically opening the waste discharge channel for waste liquid discharge. After the waste outlet 601 is opened, the waste liquid and scraped-off waste material flow into the external waste liquid collection device connected to the hose of the collection shell 6 under the action of gravity, achieving residue-free discharge. After cleaning is completed, the cleaning motor 3 reverses, and the lead screw 301 drives the cleaning blade 10 and support rod 11 to retract. After the support rod 11 disengages from the baffle plate 9, the return spring 8 pushes the baffle plate 9 to reset, re-closing the waste outlet 601 to prevent backflow of external pollutants or waste liquid retention. The moving shell 2 is then cleaned. The movable housing 2, through the sliding engagement of the bottom sliding sleeve 201 and the slide rail 12, can adjust the horizontal position of the nozzle or workpiece during sandblasting to adapt to different processing needs, enabling real-time monitoring and maintenance. The observation window 101 allows operators to visually inspect the sandblasting effect and waste liquid collection status. The design of the operating port 102 simplifies the installation and replacement process of the sandblasting pipeline and nozzle, preventing leakage and corrosion. The sealing design of the baffle plate 9, combined with the forced closure of the return spring 8, ensures the airtightness during the non-discharge stage. Timely scraping of waste reduces the long-term erosion of the collection housing 6 by corrosive substances.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
