Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically to a rotary automatic sandblasting mechanism with continuous large and small drive. Background Technology

[0002] A sandblasting machine is a mechanical device that uses compressed air to propel abrasive materials (metallic and non-metallic) onto the surface of a workpiece. It uses compressed air to transport powdery granular material from one point to another within a pipeline. During this process, kinetic energy is converted into potential energy, causing the high-speed moving sand particles to scour the surface of the object, thereby improving its surface quality.

[0003] Existing sandblasting machines generally have a structure with large and small turntables. For example, the authorization announcement number CN220179068U announces a turntable-type automatic sandblasting machine, which includes: a sandblasting machine body, a large turntable inside the sandblasting machine body, a motor inside the bottom of the large turntable, a small turntable fixedly connected to the top of the motor, a top column inside the small turntable, a slot on the surface of the bottom end of the top column, a soft clamp inside the small turntable, a locking block fixedly connected to one end of the soft clamp, a button fixedly connected to one end of the bottom end of the soft clamp, and springs at one end of the top column and the soft clamp.

[0004] Existing technology uses a top post installed inside a small turntable. When a cup is placed on it, the bottom of the cup presses down on the top post. As the top post presses down, the slot at the bottom of the top post disengages from the locking block at one end of the soft clamp. Under the action of a spring, the soft clamp pops out, thus securing the cup. This existing technology uses a mold base that matches the cup to hold it. However, when sandblasting workpieces of other shapes, different mold bases need to be installed, requiring the small turntable and mold bases to be disassembled and reassembled one by one, which is particularly time-consuming and labor-intensive. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rotary automatic sandblasting mechanism with continuous large and small drive, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary automatic sandblasting mechanism with continuous large and small drive, comprising a body, a reduction motor disposed within the body, and a large rotary disk connected to the output shaft of the reduction motor. Bearings are uniformly mounted circumferentially on the large rotary disk, and a small rotary disk is rotatably connected to each bearing. Gears are fixedly connected to the bottom of each small rotary disk. A sandblasting gun mechanism and an arc-shaped rack are disposed on the left side of the body, and the arc-shaped rack meshes with several gears on the left side. A mold base is inserted into the top of the small rotary disk, and bearings are rotatably connected to the outer side of the mold base. Insertion holes are provided on the outer ring of each bearing. A moving mechanism is uniformly disposed on the top of the large rotary disk, and movable rods are uniformly hinged to the moving mechanism. Inserted rods are hinged to the movable rods and inserted into the insertion holes. The inserted rods are slidably connected to a groove on the large rotary disk.

[0007] Preferably, the moving mechanism includes a fixed rod, all of which are hinged to the fixed rod. The fixed rod is slidably connected to a groove on the large turntable, and the fixed rod is threaded with screws that are fixedly connected to the large turntable.

[0008] Preferably, a baffle is provided inside the machine body, and through grooves are provided at both ends of the baffle. Rubber strips are provided in both through grooves. The baffle and through grooves are higher than the large turntable, and the rubber strips are in contact with the top of the large turntable.

[0009] Preferably, the front side of the machine body is connected to a door via a hinge.

[0010] Preferably, the right side of the machine body is provided with a pick-up and put-out slot, and the right side of the machine body is connected by a hinge to a second door covering the pick-up and put-out slot.

[0011] Preferably, the top of the machine body is provided with a dust suction pipe that communicates with an external dust collector, and the bottom of the machine body is also provided with a discharge port.

[0012] This invention provides a rotary automatic sandblasting mechanism with continuous large and small drive. Compared with the prior art, it has the following advantages: 1. This rotary automatic sandblasting mechanism with continuous large and small drive features a small turntable that rotates while the large turntable rotates. The small turntable rotates on a rack and pinion via gears, causing the mold base to rotate as well. Since the insert rod is inserted into the outer ring of the bearing, the mold base rotates without obstruction and cannot be raised or lowered. This ensures that the mold base drives the workpiece to rotate and receive uniform sandblasting treatment from the sandblasting gun mechanism. When the mold base needs to be removed, several movable rods are moved simultaneously by the moving mechanism, allowing the insert rod to leave several insertion holes at the same time and also insert into several insertion holes simultaneously. This allows for the batch disassembly and assembly of several mold bases, saving time and effort.

[0013] 2. This rotary automatic sandblasting mechanism with continuous large and small drive is equipped with baffles, through slots, and rubber strips to avoid the influence of sand particles when picking up and placing workpieces or disassembling and assembling mold bases. In order to avoid the inconvenience of placing a single large workpiece on the large turntable due to the baffle, a pick-and-place slot is set on the machine body, and a second door is set at the pick-and-place slot. This allows a single large workpiece to be placed separately in the middle of the large turntable when sandblasting is required, thereby facilitating the sandblasting mechanism to quickly process different workpieces.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] See Figures 1-4 This utility model provides the following two technical solutions: The first embodiment: A rotary automatic sandblasting mechanism with continuous large and small drive includes a body 1. The body 1 is equipped with a geared motor that is powered and controlled by existing technology. The output shaft of the geared motor is connected to a large turntable 5, which is used to drive the large turntable 5 to rotate. Bearings 6 are evenly installed on the large turntable 5 in a circumferential direction. Each bearing 6 is rotatably connected to a small turntable 7. The bottom of each small turntable 7 is fixedly connected to a gear 8. A sandblasting gun mechanism and an arc rack are arranged on the left side inside the body 1. The arc rack meshes with several gears 8 on the left side. The geared motor drives the large turntable 5 to rotate, so that the bearings 6 and the small turntable 7 rotate accordingly. When rotating to the arc rack, through the processing of existing technology, the gears 8 can smoothly mesh with the arc rack, so that when rotating to the left side, it can rotate on its own, so as to facilitate uniform sandblasting through the sandblasting gun mechanism. It can also place a single large workpiece in the middle of the large turntable 5 for sandblasting. A mold base 9 is inserted into the top of the small turntable 7, so that the rotation of the small turntable 7 can drive the mold base 9 to rotate. To prevent the mold base 9 from rising or falling, a bearing 2 10 is rotatably connected to the outside of the mold base 9. The outer ring of the bearing 2 10 is provided with insertion holes 11. The top of the large turntable 5 is evenly provided with a moving mechanism, and movable rods 13 are evenly hinged on the moving mechanism. Insert rods 14 are hinged to the movable rods 13 and inserted into the insertion holes 11. The insert rods 14 are slidably connected to the slide grooves 15 opened on the large turntable 5. The slide grooves 15 are used to accommodate the insert rods 14. 4. Guiding mechanism: Since the insert rod 14 is inserted into the insertion hole 11 of the outer ring of the bearing 2 10, the outer ring of the bearing 2 10 cannot be raised, lowered, or rotated. The mold base 9 can rotate freely through the inner ring of the bearing 2 10 and cannot be raised or lowered, thus ensuring the position of the mold base 9. When the mold base 9 needs to be removed, several movable rods 13 are moved simultaneously by the moving mechanism, so that the insert rod 14 can leave several insertion holes 11 at the same time, and can also be inserted into several insertion holes 11 at the same time. Thus, several mold bases 9 can be disassembled and assembled in batches, saving time and effort.

[0018] The moving mechanism includes a fixed rod 16, and movable rods 13 are hinged to the fixed rod 16. The fixed rod 16 is slidably connected to a second slide groove 17 opened on the large turntable 5. The slide groove 17 is used to guide the fixed rod 16, and the fixed rod 16 is threaded with a screw 18 that is fixedly connected to the large turntable 5. The screw 18 is used to fix the position of the fixed rod 16, thereby fixing the position of the insertion rod 14. When it is necessary to remove it, loosen the screw 18, move the fixed rod 16, and the movable rods 13 will move accordingly.

[0019] Both slide 15 and slide 27 are designed to be continuous from top to bottom to avoid the accumulation of sand particles.

[0020] To prevent sand and dust from overflowing during sandblasting, a baffle 2 is installed inside the machine body 1. Both ends of the baffle 2 are provided with through grooves 3, and rubber strips 4 are installed in both through grooves 3. The baffle 2 and through grooves 3 are higher than the large turntable 5. The rubber strips 4 are in contact with the top of the large turntable 5. The rubber strips 4 do not affect the workpiece from rotating out with the large turntable 5, and can brush off the residue on the workpiece. They can also prevent the workpiece from being affected by sand particles when picking up or putting down the workpiece or disassembling the mold base 9.

[0021] To better protect the processing, a door 19 is connected to the front of the machine body 1 via a hinge.

[0022] Because of the baffle 2, it is not convenient to place a single large workpiece on the large turntable 5. Therefore, a pick-and-place slot is provided on the right side of the machine body 1. The right side of the machine body 1 is connected by a hinge to a box door 20 covering the pick-and-place slot. When a single large workpiece needs to be sandblasted, it can be placed separately in the middle of the large turntable 5 by opening the box door 20 and then placing it in the pick-and-place slot. This makes it easier for the sandblasting mechanism to quickly process different workpieces.

[0023] The second implementation method differs from the first implementation method in that: the top of the machine body 1 is provided with a dust suction pipe 21 that is connected to an external dust collector for sucking up dust and protecting the working environment of the machine body 1; the bottom of the machine body 1 is also provided with a discharge port for discharging recycled sand particles.

[0024] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
