Description

Technical Field

[0001] This application relates to the field of shot blasting machines, and more specifically, to a device for quickly replacing the inlet and outlet rubber sheets of a shot blasting machine. Background Technology

[0002] Current steel pipe shot blasting machines use a high-speed rotating shot blaster to launch steel shot and shrapnel, impacting, cleaning, and improving the surface roughness and quality of steel pipes to achieve the target surface roughness. Currently, steel pipes used in shot blasting have varying outer diameters and large size differences, requiring frequent and time-consuming replacement of the inlet and outlet rubber sheets. To reduce the time lost during replacement, old rubber sheets are often simply hung on top of existing ones. However, this method leads to severe steel shot splattering, posing safety hazards, significantly increasing the frequency of refilling the shot hopper, and also increasing steel shot consumption. Utility Model Content

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0004] To address the technical problems mentioned in the background section, some embodiments of this application provide a device for quickly replacing the inlet and outlet rubber sheets of a shot blasting machine. This device is installed at the inlet and outlet of the shot blasting machine and includes:

[0005] A variable diameter plate is installed on the inlet and outlet of the shot blasting machine, and the first discharge port is opened on the variable diameter plate.

[0006] Iron rings are mounted on the variable diameter plate;

[0007] A polyurethane plate is installed between the reducing plate and the iron ring, and a second discharge port is provided on the polyurethane plate.

[0008] The diameter of the first discharge port is matched with the outer diameter of the steel pipe; and the size of the first discharge port on the reducing plate is changed according to the outer diameter of the steel pipe by changing different reducing plates.

[0009] This application allows for the replacement of different specifications of reducing plates according to the outer diameter of the steel pipe, thereby changing the diameter of the first discharge port on the reducing plate. This reduces the workload and frequency of employees replacing polyurethane rubber sheets, while also reducing shot blasting splashes, significantly reducing the amount of steel shot used. The operation is simple and convenient, further reducing the time spent changing tooling rubber sheets and improving production pace and actual efficiency.

[0010] Furthermore, the variable diameter plate is fixed to the inlet and outlet of the shot blasting machine by a positioning pin.

[0011] Furthermore, the iron ring is fixed to the variable diameter plate by a positioning pin.

[0012] Furthermore, there are several positioning pins, which are evenly distributed along the axial direction of the variable diameter plate or iron ring.

[0013] Furthermore, the diameter of the variable diameter plate is larger than the diameter of the iron ring and the polyurethane plate.

[0014] Furthermore, a driving component is provided on the variable diameter plate, and a receiving cavity is opened on the variable diameter plate. One side of the receiving cavity is connected to the first discharge port. Several slide rods connected to the driving component are installed in the receiving cavity. Each slide rod is provided with a connecting plate. Several connecting plates surround to form a third discharge port. The diameter of the third discharge port is smaller than the diameter of the first discharge port.

[0015] Furthermore, one end of the connecting plate has an arc-shaped portion.

[0016] Furthermore, the driving component includes:

[0017] The motor is fixed on the outer wall of the variable diameter plate, and the output end of the motor extends into the receiving cavity;

[0018] The gear is fixedly mounted on the output end and located inside the receiving cavity;

[0019] A turntable is rotatably disposed within a receiving cavity, and a rack that meshes with a gear is provided on the outer wall of the turntable;

[0020] There are several connecting rods, one end of which is rotatably connected to the turntable, and the other end is rotatably connected to the slide rod;

[0021] The variable diameter plate has a first limiting groove that communicates with the receiving cavity, and one end of the slide rod is slidably inserted into the first limiting groove.

[0022] Furthermore, the slide bar is provided with an elastic locking block, and the variable diameter plate is provided with a locking groove that communicates with the first limiting groove, and the elastic locking block cooperates with the locking groove.

[0023] Furthermore, a second limiting groove is provided on the turntable, and a limiting rod is provided in the receiving cavity, with the limiting rod located in the second limiting groove.

[0024] The beneficial effects of this application are as follows: by replacing the reducer plate with different specifications according to the outer diameter of the steel pipe, the diameter of the first discharge port on the reducer plate can be changed. This reduces the workload and frequency of employees replacing polyurethane rubber sheets, while also reducing the splashing of shot from the shot blasting machine, greatly reducing the amount of steel shot used. The operation is simple and convenient, thereby reducing the time spent replacing tooling rubber sheets and improving production rhythm and actual efficiency. Attached Figure Description

[0040] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Reference Figure 1-2 This device allows for quick replacement of the inlet and outlet rubber sheets of a shot blasting machine. Installed at the inlet / outlet 1 of the shot blasting machine, it includes a variable diameter plate 2, an iron ring 3, a polyurethane plate 4, and a positioning pin 5. The variable diameter plate 2 is mounted on the inlet / outlet 1 of the shot blasting machine via the positioning pin 5. The iron ring 3 is mounted on the variable diameter plate 2 via the positioning pin 5. The polyurethane plate 4 is installed between the variable diameter plate 2 and the iron ring 3. The variable diameter plate 2 has a first discharge port 6, and the polyurethane plate 4 has a second discharge port 7. The polyurethane plate 4 is made of polyurethane rubber. Specifically, the diameter of the first discharge port 6 is matched to the outer diameter of the steel pipe. Different sizes of variable diameter plates 2 are used to change the diameter of the first discharge port 6, depending on the outer diameter of the steel pipe. This reduces the workload and frequency of changing the polyurethane rubber sheets, reduces shot splatter, significantly reduces the amount of steel shot used, and is simple and convenient to operate. It also reduces the time spent changing tooling rubber sheets, improving production speed and actual efficiency.

[0042] There are several positioning pins 5, which are evenly distributed along the axis of the variable diameter plate 2 or the iron ring 3.

[0043] The diameter of the variable diameter plate 2 is larger than the diameter of the iron ring 3 and the polyurethane plate 4.

[0044] Reference Figure 3-6In another embodiment, this application does not require replacing the variable diameter plate 2, but instead installs a device on the variable diameter plate 2 that can change the size of the first discharge port 6. Specifically, a driving component is provided on the variable diameter plate 2, and a receiving cavity 8 is opened on the variable diameter plate 2. One side of the receiving cavity 8 is connected to the first discharge port 6. Several sliding rods 9 connected to the driving component are installed in the receiving cavity 8. Each sliding rod 9 is provided with a connecting plate 10. One end of the connecting plate 10 has an arc-shaped portion 11. Several connecting plates 10 surround to form a third discharge port 12. The diameter of the third discharge port 12 is smaller than the diameter of the first discharge port 6.

[0045] The driving components include a motor 13, a gear 14, a turntable 15, and connecting rods 16. The motor 13 is fixedly mounted on the outer wall of the variable diameter plate 2, and the output end of the motor 13 extends into the receiving cavity 8. The gear 14 is fixedly mounted on the output end and located in the receiving cavity 8. The turntable 15 is rotatably mounted in the receiving cavity 8, and a rack 17 that meshes with the gear 14 is provided on the outer wall of the turntable 15. There are several connecting rods 16, one end of which is rotatably connected to the turntable 15, and the other end is rotatably connected to the slide rod 9. A first limiting groove 18 communicating with the receiving cavity 8 is provided on the variable diameter plate 2, and one end of the slide rod 9 is slidably inserted into the first limiting groove 18.

[0046] The slide bar 9 is equipped with an elastic locking block 19, and the variable diameter plate 2 has a locking groove 20 that communicates with the first limiting groove 18. The elastic locking block 19 cooperates with the locking groove 20. The elastic locking block 19 can be divided into a first elastic locking block 19a, a second elastic locking block 19b, and a third elastic locking block 19c, which are distributed sequentially along the length of the slide bar 9. When the first elastic locking block 19a cooperates with the locking groove 20, making the diameter of the third feed inlet formed by the connecting plate 10 larger than the diameter of the third feed inlet formed by the second elastic locking block 19b / third elastic locking block 19c and the locking groove 20, the elastic locking block 19 will engage in the locking groove 20, thereby fixing the connecting plate 10 under the action of the elastic locking block 19. At the same time, the elastic blocks 19 at different positions are respectively inserted into the slots 20, thereby playing the role of gear adjustment, which is relative to the size of the third feed port diameter.

[0047] This application provides a groove 21 on the slide bar 9 that corresponds to the first elastic block 19a, the second elastic block 19b, and the third elastic block 19c. A spring 22 is installed in the groove 21, and one end of the spring 22 is connected to the first elastic block 19a, the second elastic block 19b, and the third elastic block 19c respectively.

[0048] The turntable 15 has a second limiting groove 23, and the receiving cavity 8 has a limiting rod 24, which is located in the second limiting groove 23.

[0049] The specific operation process is as follows:

[0050] The diameter of the third feed inlet is adjusted according to the outer diameter of the steel pipe. The motor 13 drives the gear 14 to rotate, and the gear 14 drives the turntable 15 to rotate. The turntable 15 rotates in a circle under the action of the limiting rod 24 and the second limiting groove 23. The turntable 15 drives the connecting rod 16 to move, and the connecting rod 16 drives the sliding rod 9 to move. The sliding rod 9 moves along the length of the first limiting groove 18 in the first limiting groove 18. The sliding rod 9 drives the connecting plate 10 to move into the first feed inlet, so that several connecting plates 10 surround each other to form the third feed inlet. The diameter of the third feed inlet is adapted to the outer diameter of the newly replaced steel pipe.
