Description

Technical Field

[0001] This utility model relates to the field of shot blasting equipment technology, specifically a shot blasting machine. Background Technology

[0002] A shot blasting machine is a mechanical device that uses a high-speed shot stream to treat the surface of a workpiece. It is widely used in industries such as machinery manufacturing, automobiles, and shipbuilding. It uses a shot blaster to propel shot at high speed, impacting the workpiece surface to achieve functions such as rust removal, deburring, and surface strengthening, thereby improving the appearance quality and mechanical properties of the workpiece.

[0003] Utility model patent CN219027185U discloses an energy-saving and environmentally friendly shot blasting machine. This machine includes a fixed base plate, with the shot blasting machine body fixedly connected to its top. Multiple anti-slip structures are fixedly connected to the bottom of the base plate. A drive motor is fixedly connected to one end of the shot blasting machine body, and the output end of the drive motor extends into the interior of the machine body and is fixedly connected to a processing chamber. Multiple collection troughs are fixedly connected to the outside of the processing chamber, and multiple fixing holes are provided on the outside of the processing chamber. This energy-saving and environmentally friendly shot blasting machine utilizes an installation structure to connect and fix the shot blasting machine body and the disassembly plate. Bolts rotate and pass through the sides of the shot blasting machine body and the disassembly plate. The position of the bolts is limited by the cooperation of a limiting plate, connecting spring, and fixing plate, preventing loosening. The cooperation of a slider and a slide rail allows the limiting plate to move more smoothly.

[0004] This energy-saving and environmentally friendly shot blasting machine does not have a dedicated internal wall cleaning structure. After shot blasting, shot and impurities are easily left on the inner wall of the processing chamber and the shot blasting machine itself. Long-term accumulation not only affects the shot blasting effect, but also requires manual cleaning. The cleaning process is cumbersome and there are blind spots, making it difficult to ensure the cleanliness of the inner wall and affecting the subsequent use of the equipment. In view of this, we propose a shot blasting machine. Utility Model Content

[0005] The purpose of this invention is to provide a shot blasting machine to solve the problems mentioned in the background art.

[0008] The base has a fixed seat at its rear end, and a seat plate at the tail end of the fixed seat. A lead screw is rotatably connected to the seat plate.

[0009] The movable seat is movable along the fixed seat, and the lead screw passes longitudinally through the movable seat and is threadedly connected to the movable seat.

[0010] The rotating assembly includes a movable main shaft rotatably connected to the movable seat and a rotating plate installed at the head end of the movable main shaft. The movable main shaft passes through the shot blasting machine body and is rotatably connected to the shot blasting machine body. The rotating plate is located inside the working chamber.

[0011] The cleaning assembly includes several third motors fixed to the rear end face of the rotating plate and a rotating sleeve coaxially connected to the end of the output shaft of the third motor. The rotating sleeve is located on the front side of the rotating plate, and several bristles are installed on the outer surface of the rotating sleeve.

[0012] Preferably, a first motor is mounted on the rear end face of the seat plate, and the output shaft end of the first motor is coaxially connected to the lead screw, and the first motor can drive the lead screw to rotate;

[0013] In this configuration, the first motor powers the lead screw, which in turn drives the movable seat longitudinally via a threaded transmission.

[0014] Preferably, a plurality of guide rods are fixed between the seat plate and the tail of the shot blasting machine body, the guide rods extending longitudinally through the movable seat, and the movable seat being able to move along the guide rods;

[0015] In this configuration, the guide rod guides and limits the movement of the movable seat, ensuring smooth movement.

[0016] Preferably, a second motor is mounted on the rear end face of the movable seat, and the end of the output shaft of the second motor is coaxially connected to the movable main shaft. The second motor can drive the rotating assembly to rotate.

[0017] In this configuration, the second motor drives the rotating assembly to rotate, causing the cleaning assembly to perform a circumferential cleaning of the inner wall of the working chamber.

[0018] Preferably, a sealing ring made of rubber material is provided at the outer peripheral edge of the front end face of the rotating plate. The sealing ring has an annular sheet structure, and the outer peripheral edge of the sealing ring abuts against the inner wall of the working cavity.

[0019] In this configuration, the sealing ring reduces the leakage of impurities from the working chamber and seals the gap between the rotating plate and the inner wall, allowing the sealing ring to push the impurities generated during cleaning forward when the inner wall cleaning mechanism moves forward.

[0020] Preferably, the cleaning components are distributed in a ring at equal intervals on the outer periphery of the rotating plate, and the ends of the bristles can abut against the inner wall of the working chamber;

[0021] In this setup, the equally spaced, ring-shaped cleaning components ensure that the bristles make full contact with the inner wall, achieving effective cleaning.

[0022] Preferably, the movable spindle passes through the rotating plate and is fixedly connected to the protective plate. A plurality of connecting posts are fixed between the rotating plate and the protective plate. The protective plate is used to protect the cleaning assembly.

[0024] Preferably, when the inner wall cleaning mechanism moves toward the front end of the shot blasting machine body, the rotating plate extends out from the opening of the working chamber;

[0025] This setup facilitates the inspection or replacement of the cleaning components and ensures that the cleaning covers the entire inner wall area. It also allows the sealing ring to push out impurities generated during cleaning from the shot blasting machine body.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This shot blasting machine, through its internal wall cleaning mechanism, uses the threaded transmission of the movable seat and lead screw, and is precisely guided by the guide rod, to achieve longitudinal displacement of the cleaning component. By starting the second motor, the rotating component is driven to rotate, and the third motor in the cleaning component synchronously drives the rotating sleeve and brush bristles to rotate at high speed. During operation, the rotating component drives the cleaning component to move axially while cleaning around the inner wall of the working chamber, achieving all-round cleaning of the inner wall of the working chamber, keeping the working chamber clean, and providing a good environment for shot blasting operations.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0038] Please see Figures 1-5 A shot blasting machine includes a shot blasting machine body 100, a working chamber 110 inside the shot blasting machine body 100, a base 120 at the bottom end of the shot blasting machine body 100, and an inner wall cleaning mechanism 200 for cleaning the inner wall of the working chamber 110. The inner wall cleaning mechanism 200 includes a movable seat 210 located at the rear end of the shot blasting machine body 100, a rotating component 220 mounted on the movable seat 210 and rotatably connected to the movable seat 210, a plurality of cleaning components 230 mounted on the rotating component 220, and a protective plate 240 mounted at the head end of the rotating component 220. By setting the inner wall cleaning mechanism 200, the inner wall of the working chamber 110 is cleaned, so that the working chamber 110 is kept clean.

[0039] like Figure 1 and Figure 3As shown, in this utility model, a fixed seat 130 is provided at the rear end of the base 120, and a seat plate 131 is provided at the tail end of the fixed seat 130. A lead screw 140 is rotatably connected to the seat plate 131. A first motor 141 is mounted on the rear end face of the seat plate 131. The output shaft end of the first motor 141 is coaxially connected to the lead screw 140, and the first motor 141 can drive the lead screw 140 to rotate. The movable seat 210 can move along the fixed seat 130, and the lead screw 140 passes through the movable seat 210 longitudinally and is threadedly connected to the movable seat 210. By starting the first motor 141, the first motor 141 can drive the lead screw 140 to rotate. Through the threaded transmission between the lead screw 140 and the movable seat 210, the movable seat 210 can move longitudinally along the fixed seat 130, providing power for the axial movement of the inner wall cleaning mechanism 200.

[0040] like Figure 3 As shown, furthermore, several guide rods 150 are fixed between the seat plate 131 and the tail of the shot blasting machine body 100. The guide rods 150 longitudinally penetrate the movable seat 210, allowing the movable seat 210 to move along the guide rods 150. The guide rods 150 guide and limit the movement of the movable seat 210, ensuring that the movable seat 210 moves smoothly and accurately longitudinally under the drive of the lead screw 140, and avoiding deviation.

[0041] like Figure 1 and Figure 4 As shown, the rotating assembly 220 includes a movable main shaft 221 rotatably connected to the movable seat 210 and a rotating plate 222 mounted on the head end of the movable main shaft 221. The movable main shaft 221 passes through the shot blasting machine body 100 and is rotatably connected to the shot blasting machine body 100. The rotating plate 222 is located inside the working chamber 110. The rotating assembly 220 constitutes the rotating carrier of the cleaning assembly 230, and its rotation can drive the cleaning assembly 230 to perform circumferential cleaning of the inner wall of the working chamber 110.

[0042] like Figure 4 As shown, it is worth noting that a second motor 2211 is mounted on the rear end face of the movable seat 210. The output shaft of the second motor 2211 is coaxially connected to the movable main shaft 221, and the second motor 2211 can drive the rotating assembly 220 to rotate. The second motor 2211 provides rotational power to the rotating assembly 220, enabling the rotating plate 222 and the cleaning assembly 230 to rotate within the working chamber 110, thereby achieving circumferential cleaning of the inner wall.

[0043] It should be added that a sealing ring 2221 made of rubber material is provided at the outer peripheral edge of the front end face of the rotating plate 222. The sealing ring 2221 has an annular sheet structure, and its outer peripheral edge abuts against the inner wall of the working chamber 110. The sealing ring 2221 can reduce the leakage of impurities from the working chamber 110 when the rotating assembly 220 is working. At the same time, it can seal the gap between the rotating assembly 220 and the inner wall of the working chamber 110, preventing impurities from seeping into the working chamber 110 behind the inner wall cleaning mechanism 200. In addition, the sealing ring 2221 can push the cleaned impurities outward when the inner wall cleaning mechanism 200 moves forward.

[0044] like Figure 4 and Figure 6 As shown, it is worth noting that the cleaning assembly 230 includes several third motors 231 fixed to the rear end face of the rotating plate 222 and a rotating sleeve 232 coaxially connected to the end of the output shaft of the third motors 231. The rotating sleeve 232 is located on the front side of the rotating plate 222, and several bristles 2321 are installed on the outer surface of the rotating sleeve 232. The cleaning assembly 230 is distributed in a ring at equal intervals on the outer periphery of the rotating plate 222, and the ends of the bristles 2321 can abut against the inner wall of the working chamber 110. By starting the third motors 231, the third motors 231 can drive the rotating sleeve 232 and the bristles 2321 to rotate. The ring-shaped cleaning assembly 230 can contact the inner wall of the working chamber 110 from all directions, and the friction of the bristles 2321 effectively removes the residual impurities on the inner wall.

[0045] like Figure 5 As shown, furthermore, the movable spindle 221 passes through the rotating plate 222 and is fixedly connected to the protective plate 240. Several connecting posts 2222 are fixed between the rotating plate 222 and the protective plate 240. The protective plate 240 is used to protect the cleaning assembly 230. The protective plate 240 can prevent the cleaning assembly 230 from being damaged by the impact of polishing balls during operation. The connecting posts 2222 ensure a stable connection between the protective plate 240 and the rotating plate 222, extending the service life of the cleaning assembly 230.

[0046] like Figure 2 As shown, further, when the inner wall cleaning mechanism 200 moves towards the front end of the shot blasting machine body 100, the rotating plate 222 extends from the opening of the working chamber 110. This design facilitates the maintenance or replacement of the cleaning assembly 230 when necessary. Simultaneously, during the cleaning process, the rotating plate 222 and the cleaning assembly 230 can better cover various areas of the inner wall of the working chamber 110, and ultimately allow impurities generated during cleaning to be pushed out of the working chamber 110 by the sealing ring 2221, preventing impurities from accumulating inside the working chamber 110.

[0047] It is worth noting that the first motor 141, the second motor 2211 and the third motor 231 involved in this utility model are all existing conventional technologies, and will not be described in detail in this utility model.

[0048] In this embodiment, when the shot blasting machine is in use, firstly, the first motor 141 is started, causing the lead screw 140 to rotate. Under the action of the thread of the lead screw 140, the lead screw 140 drives the movable seat 210 to move longitudinally along the guide rod 150. Then, the second motor 2211 is started, causing the second motor 2211 to drive the rotating assembly 220 to rotate. At this time, the rotating plate 222 and the cleaning assembly 230 rotate around in the working chamber 110. Next, the third motor 231 is started, causing the third motor 231 to drive the rotating sleeve 232 and the bristles 2321 to rotate at high speed, so that the cleaning assembly 230 cleans the inner wall of the working chamber 110. Finally, under the rotation and axial movement of the rotating assembly 220, the cleaning assembly 230 on the rotating assembly 220 cleans the working chamber 110 as a whole. After cleaning is completed, the first motor 141 is started again, causing the inner wall cleaning mechanism 200 to retract into the working chamber 110 for subsequent shot blasting operations.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
