Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, and in particular to a sandblasting device for aluminum profiles for doors and windows. Background Technology

[0002] In the fields of architectural decoration and door and window manufacturing, the surface treatment of aluminum profiles for doors and windows is crucial. It not only affects the aesthetics of doors and windows but also significantly impacts their corrosion resistance, wear resistance, and other properties. Sandblasting, as a common and effective surface treatment process, can remove impurities such as oxide scale and oil stains from the aluminum surface, while simultaneously creating a certain roughness to enhance the adhesion of subsequent coatings. Therefore, it is widely used in the processing of aluminum profiles for doors and windows.

[0003] However, existing aluminum profile sandblasting equipment for doors and windows has the following drawbacks in practical applications: In order to solve the dust prevention problem, traditional aluminum profile sandblasting equipment for doors and windows usually sets up a box with curtains installed at both ends of the box to reduce the probability of dust leakage. However, this method of the profile passing through one end of the box and exiting from the other end means that the length of the entire working area must be more than twice the length of the profile itself, which occupies a lot of indoor space. The large space requirement also limits the company's optimization of production layout. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a sandblasting device for aluminum materials used in doors and windows.

[0005] The technical solution of this utility model is a sandblasting device for aluminum materials for doors and windows, which includes a sandblasting box, a nozzle mounting base, and a sandblasting device.

[0006] The sandblasting box includes a first box and a second box. A first bracket and a second bracket are respectively provided at the bottom of the first and second boxes. The end of the second box is slidably mounted inside the first box. A first driving device for adjusting its extension length is installed at the bottom of the sandblasting box. The front ends of the first and second boxes, as well as the opposite ends of the first and second boxes, are all open. Multiple first curtains are installed at the front opening of the first box, and multiple second curtains are installed at the front opening of the second box. Profile brackets are provided at the inner side of the first box away from the second box and at both inner ends of the second box. A nozzle mounting seat is slidably mounted on the top inner side of the sandblasting box. A second driving device for driving the nozzle mounting seat to move is installed on the sandblasting box. The sandblasting device includes a sandblasting machine and a nozzle. The sandblasting machine is mounted on the first bracket, and the nozzle is mounted on the nozzle mounting seat. A flexible hose connects the output end of the sandblasting machine to the nozzle.

[0007] Preferably, the first box and the second box are respectively provided with a first elongated hole and a second elongated hole for the flexible hose to pass through. Multiple third curtains are installed inside the first elongated hole, and multiple fourth curtains are installed inside the second elongated hole.

[0008] Preferably, the first driving device includes a second servo motor, a threaded rod, and a threaded sleeve. The second servo motor is installed at one end of the bottom of the second housing. The threaded rod is connected to the output shaft of the second servo motor. The threaded sleeve is connected to the first housing and is threadedly connected to the threaded rod.

[0009] Preferably, the second drive device includes two sets of traction components, which are respectively installed at both ends of the sandblasting box. The traction components include a first servo motor, a take-up reel, and a traction rope. The first servo motor is installed on the sandblasting box, the take-up reel is installed on the output shaft of the first servo motor, and the traction rope moves through the inner and outer sides of the corresponding side of the sandblasting box. One end of the traction rope is fixedly wound on the take-up reel, and the other end is connected to the nozzle mounting seat.

[0010] Preferably, four sets of telescopic rod assemblies are connected between the first box and the second box. Each of the four sets of telescopic rod assemblies includes a sleeve and a movable rod. The end of the movable rod is slidably installed on the inner side of the sleeve.

The other two sets of telescopic rod assemblies have two sleeves and two movable rods connected to the inner walls of the second box and the first box, respectively.

[0011] Preferably, infrared ranging sensors are installed at both ends of the nozzle mounting base.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] 1. The sandblasting box consists of a first chamber and a second chamber. Its telescopic length can be adjusted via a first drive device, making it adaptable to various lengths of aluminum profiles for doors and windows, greatly improving the applicability of the device. Furthermore, when not in use or needing storage, the sandblasting box can be retracted to reduce its space occupation, significantly saving space compared to traditional sandblasting devices that require twice the length of the profile.

[0014] 2. The method of placing the profile into the sandblasting box and driving the nozzle to move for sandblasting replaces the traditional method of inserting and removing the profile, avoiding the problem of needing a lot of extra space due to the excessive length of the profile, and further optimizing space utilization.

[0015] 3.

[0019] Example 1

[0020] like Figures 1-3 As shown in the figure, the present embodiment proposes a sandblasting device for aluminum materials for doors and windows, including a sandblasting box, a nozzle mounting base 8, and a sandblasting device.

[0021] The sandblasting box includes a first box 1 and a second box 2. The bottom ends of the first box 1 and the second box 2 are respectively provided with a first bracket 3 and a second bracket 4. The end of the second box 2 is slidably installed inside the first box 1. The bottom end of the sandblasting box is equipped with a first drive device for adjusting its telescopic length. The first drive device includes a second servo motor 19, a threaded rod 20 and a threaded sleeve 21. The second servo motor 19 is installed at one bottom end of the second box 2. The threaded rod 20 is connected to the output shaft of the second servo motor 19. The threaded sleeve 21 is connected to the first box 1 and is threadedly connected to the threaded rod 20. To facilitate length adjustment, multiple self-locking casters can be installed at the bottom ends of the first bracket 3 and the second bracket 4.

[0022] The front ends of the first box 1 and the second box 2, as well as the opposite ends of the first box 1 and the second box 2, are all designed to be open. Multiple first curtains 5 are installed at the front opening of the first box 1, and multiple second curtains 6 are installed at the front opening of the second box 2. Profile brackets 14 are provided on the inner side of the first box 1 at the end away from the second box 2 and on both inner sides of the second box 2.

[0023] The nozzle mounting base 8 is slidably disposed on the top inner side of the sandblasting box. Four sets of telescopic rod assemblies connect the first box 1 and the second box 2. Each set of telescopic rod assemblies includes a sleeve 15 and a movable rod 16. The end of the movable rod 16 is slidably mounted on the inner side of the sleeve 15. Two sets of telescopic rod assemblies, comprising two sleeves 15 and two movable rods 16, are respectively connected to the inner walls of the first box 1 and the second box 2. The other two sets of telescopic rod assemblies, comprising two sleeves 15 and two movable rods 16, are respectively connected to the inner walls of the second box 2 and the first box 1. It should be noted that the nozzle mounting base 8 has four through holes for the four sleeves 15 to pass through. Mounting base 8 is slidably mounted on four sets of telescopic rod assemblies. A second driving device for driving the nozzle mounting base 8 to move is installed on the sandblasting box. The second driving device includes two sets of traction components, which are respectively installed at both ends of the sandblasting box. The traction components include a first servo motor 11, a winding reel 12, and a traction rope 13. The first servo motor 11 is mounted on the sandblasting box, the winding reel 12 is mounted on the output shaft of the first servo motor 11, and the traction rope 13 moves through the inner and outer sides of the corresponding side of the sandblasting box. One end of the traction rope 13 is fixedly wound around the winding reel 12, and the other end is connected to the nozzle mounting base 8. Infrared ranging sensors are installed at both ends of the nozzle mounting base 8.

[0024] The sandblasting device includes a sandblasting machine 7 and a nozzle 9. The sandblasting machine 7 is mounted on the first bracket 3, and the nozzle 9 is mounted on the nozzle mounting base 8. A hose 71 is connected between the output end of the sandblasting machine 7 and the nozzle 9.

[0025] Furthermore, a PLC controller 10 is installed on the sandblasting box.

[0026] The working principle of this technical solution is as follows:

[0027] Preparatory stage for sandblasting: First, the length of the sandblasting box should be adjusted according to the length of the profile to be sandblasted. The sandblasting box consists of a first box 1 and a second box 2. When the second servo motor 19 is started, its output shaft drives the threaded rod 20 to rotate. Since the threaded sleeve 21 is connected to the first box 1 and threadedly connected to the threaded rod 20, the rotation of the threaded rod 20 will cause the threaded sleeve 21 to move relative to the threaded rod 20, thereby realizing the relative sliding of the first box 1 and the second box 2, achieving the purpose of adjusting the length of the sandblasting box so that it can adapt to profiles of different lengths.

[0028] Profile placement: After adjusting the length of the sandblasting box, place the profile to be sandblasted on multiple profile supports 14 through the front opening of the sandblasting box. Multiple first curtains 5 are installed at the front opening of the first box 1, and multiple second curtains 6 are installed at the front opening of the second box 2. The function of these curtains is to minimize the outward scattering of sand during the sandblasting process when the profile is put in and taken out, and to play a certain protective role. At the same time, they can also prevent external dust and other impurities from entering the sandblasting box.

[0029] Sandblasting operation stage: The sandblasting machine 7 is mounted on the first support 3. When the sandblasting machine 7 is started, its internal power system begins to work. The sandblasting machine 7 typically uses compressed air as its power source. Inside the sandblasting machine 7, the abrasive material is stored in a specific container. When the compressed air enters the sandblasting machine 7, it forms a strong airflow. This airflow carries the abrasive material out of the storage container and delivers it to the nozzle 9 through the hose 71 connected to the output end of the sandblasting machine 7. The hose 71 has a certain degree of flexibility to adapt to the movement of the nozzle mounting base 8, ensuring continuous delivery of the abrasive material. A flexible metal hose can be installed on the outside of the hose 71 to prevent it from twisting. When the first servo motor 11 is started, its output shaft drives the winding reel 12 to rotate. The rotation of the winding reel 12 causes the traction rope 1 to rotate. 3. Perform the winding and unwinding operation. Since one end of the traction rope 13 is fixedly wound on the winding reel 12 and the other end is connected to the nozzle mounting seat 8, the nozzle mounting seat 8 can be driven to move back and forth in the sandblasting box through the coordinated work of the two sets of traction components. Both ends of the nozzle mounting seat 8 are equipped with infrared distance sensors. These sensors can monitor the distance between the nozzle mounting seat 8 and the inner wall of the sandblasting box or other objects in real time, ensuring the safety and accuracy of the nozzle mounting seat 8 during the movement. During the movement of the nozzle mounting seat 8, high-speed sand particles are ejected from the nozzle 9 and impact the surface of the aluminum material placed on the profile support 14 to perform sandblasting treatment on the aluminum material. Through the back and forth movement of the nozzle mounting seat 8, the entire surface of the profile can be covered, ensuring that all parts of the profile can be uniformly sandblasted.

[0030] In summary, this aluminum profile sandblasting device for doors and windows, with its adjustable-length sandblasting box design, is suitable for sandblasting profiles of various lengths. Furthermore, its retractable design significantly reduces space requirements, saving equipment space. Compared to traditional sandblasting devices, which require inserting the profile from one end and exiting from the other, occupying at least twice the length of the profile itself, this device effectively solves the space occupation problem by placing the profile inside the sandblasting box and driving the nozzle 9 to move, thus improving site utilization. Simultaneously, the placement of various curtains and the rational structural design ensure the sealing and safety of the sandblasting process, reducing sand scattering and interference from external impurities, thereby improving sandblasting quality and the cleanliness of the working environment.

[0031] Example 2

[0032] like Figure 2 and Figure 3 As shown in the figure, the aluminum door and window sandblasting device proposed in this embodiment, compared with the first embodiment, has a first elongated hole 101 and a second elongated hole 201 respectively opened on the first box 1 and the second box 2 for the hose 71 to pass through. Multiple third curtains 17 are installed inside the first elongated hole 101, and multiple fourth curtains 18 are installed inside the second elongated hole 201.

[0033] In this embodiment, the third curtain 17 and the fourth curtain 18 are also set up to prevent sand from flying out from the elongated hole and to ensure the sealing of the sandblasting process.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
