Description

Technical Field

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

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously perform sand removal, core removal, and cleaning of castings. In some regions, they are also colloquially called sandblasting machines or sandblasting machines. Through-type shot blasting machines use conveyor rollers to continuously transport the workpiece, allowing for continuous operation. During operation, the shot blaster propels the shot towards the workpiece surface; the high-speed shot impacts the surface and undergoes secondary ejection. During shot blasting, shot splatters outside the cleaning chamber, potentially injuring workers. Rubber protective curtains are installed at the workpiece inlet and outlet.

[0003] Chinese utility model patent CN215148219U includes a shot blasting machine body. A support base is fixedly connected to one side of the machine body. Square baffles are fixedly connected to both sides of the top of the support base. One side of each square baffle is rotatably connected to the outer wall of multiple transmission rollers. Square grooves are formed on both sides of the support base. The inner walls of each square groove are slidably connected to the outer wall of a square slider. One side of each square slider is fixedly connected to both sides of the bottom of the inner wall of a U-shaped connecting seat. This utility model, by starting a servo motor, drives the arc-shaped limiting components on two bidirectional lead screws to generate relative movement, thereby clamping the castings on the multiple transmission rollers. Pushing the U-shaped connecting seat then transmits the castings into the interior of the shot blasting machine body for cleaning or strengthening. This solves the problem of workers directly contacting the castings and the resulting danger during the feeding process.

[0004] However, it has the following drawbacks: First, the U-shaped connector is a single seat, which is not stable enough and is prone to jamming during movement; second, it uses a lead screw with opposite threads and equal pitch, which results in higher production and manufacturing costs. Utility Model Content

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

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine with protective function, comprising a shot blasting machine body 3 and a conveyor frame 1 connected thereto. The conveyor frame 1 has self-rotating conveyor rollers 2 evenly distributed on it. Symmetrical guide grooves 4 are provided on both sides of the conveyor frame 1. U-shaped seats 6 are provided on both sides of the conveyor frame 1. The U-shaped seats 6 consist of two in total and are fixedly connected by a gearbox 7 above. A gear 10 and two racks 11 are provided in the center of the gearbox 7. The racks 11 are arranged symmetrically with the gear 10 as the center. A connecting plate 8 connected to a limiting plate 5 is provided on one side of the racks 11. The gear 10 is connected to a motor 9 on the top of the gearbox 7.

[0007] Furthermore, each of the U-shaped seats 6 is provided with a guide rod 14 in the middle.

[0008] Furthermore, the gearbox 7 has rack guide grooves 12 on both sides and a clearance groove 13 at the bottom.

[0009] Furthermore, the bottom sides of the U-shaped seat 6 are provided with rollers 15 that cooperate with the guide groove 4.

[0010] This utility model has the following advantages: First, it is equipped with two U-shaped bases, which increases stability and avoids jamming or tipping over during transmission; second, it uses gears and racks, which are simpler to process, thus reducing production costs.

[0015] 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.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a shot blasting machine with protective function, including a shot blasting machine body 3 and a conveyor frame 1 connected thereto. The conveyor frame 1 has self-rotating conveyor rollers 2 evenly distributed on it. The conveyor frame 1 has symmetrical guide grooves 4 on both sides. The conveyor frame 1 has U-shaped seats 6 on both sides. The bottom sides of the U-shaped seats 6 are provided with rollers 15 that cooperate with the guide grooves 4.

[0017] There are two U-shaped seats 6, which are fixedly connected by the gear box 7 above, which improves the stability of the U-shaped seats 6 when moving.
