Description

Technical Field

[0001] The utility model relates to the technical field of production of biodegradable plastic products, in particular to a protective device for a shot blasting machine. Background Art

[0002] Biodegradable plastics refer to a type of plastic that is degraded by microorganisms such as bacteria, molds and algae that exist in nature. An ideal biodegradable plastic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and eventually becomes inorganic and becomes a part of the carbon cycle in nature. During production, biodegradable plastics need to be processed using a shot blasting machine.

[0003] At present, the shot blasting machine is equipped with functions such as automatic lifting, feeding and discharging, and adopts multiple lifting functions at the feeding port. During the processing, if slipping occurs or pedestrians mistakenly enter the lifting hopper, it is very dangerous and there are safety hazards.

[0004] For example, a protective device for a shot blasting machine disclosed in Chinese patent CN219189871U fixes the mounting strips on both sides of the shot blasting machine body by bolts, the first connecting strip corresponds to the extended connecting strip, the card block is inserted into the card slot, the card block squeezes the card ball, so that the spring contracts, and when the card ball corresponds to the arc groove, the spring rebounds, so that the card ball is inserted into the arc groove, thereby completing the card connection between the first connecting strip and the extended connecting strip. When it is necessary to adjust the length of the protective device, several extended connecting strips can be carded, and the effect of adjusting the overall length can be achieved by increasing or decreasing the number of extended connecting strips. The staff can increase or decrease the number of extended connecting strips at any time according to needs. It has strong flexibility, is easy to adjust, and is simple to operate. When the shot blasting machine body needs to be moved, it is more convenient to disassemble by card connection.

[0005] However, the protective device cannot be rotated, so the angle of the protective net cannot be adjusted, and the position angle of the entire protective device cannot be adjusted according to the required feeding trajectory.

[0006] For this reason, we urgently need to provide a kind of shot blasting machine protective device with adjustable angle. Utility Model Content

[0007] The utility model aims to provide a protective device for a shot blasting machine to solve the problem that the protective device proposed in the above background technology cannot be rotated, so that the angle of the protective net cannot be adjusted, and the overall position angle of the protective device cannot be adjusted according to the required feeding trajectory.

[0010] A further improvement is that a circular hole is provided in the middle of the fixing rod, a threaded groove is provided in the middle of the left front and rear ends of the shot blasting machine body, the outer side of the bolt is slidably connected to the inner side of the circular hole, and the outer side of the push rod is threadedly connected to the inner side of the threaded groove. Thus, after the bolt passes through the circular hole and is threadedly connected to the threaded grooves at the front and rear ends of the shot blasting machine body, the fixing rod can be fixed to the left ends of the front and rear ends of the shot blasting machine body.

[0011] A further improvement is that a circular groove is provided above the middle position of the left and right ends of the top rod, the lower end of the spring is fixedly connected to the inner bottom end of the circular groove, and the outer side of the insertion rod is slidably connected to the inner side of the circular groove. Therefore, when the spring is activated, the insertion rod can be driven to slide along the inner side of the circular groove, thereby limiting the movement of the insertion rod.

[0012] A further improvement is that grooves are provided at the left and right ends of the upper and lower parts of the straight connecting rod, the upper and lower ends of the right part of the first rotating plate, and the upper and lower ends of the left part of the second rotating plate.

The outer side of the right end of the bottom rod is slidably connected to the inner side of the fixing groove. The outer sides of the left and right ends of the bottom rod are slidably connected to the inner side of the groove.

Similarly, the top rod can be fixed to the grooves of the straight connecting rod, the first rotating plate, and the second rotating plate, so that the protective net is connected.

[0013] A further improvement is that a rotation hole is provided at the middle position of the right end of the second rotating plate, a through slot is provided at the left end of the first rotating plate, the upper and lower ends of the rotating rod are fixedly connected to the upper and lower ends of the inner side of the through slot, and the outer side of the rotating rod is rotationally connected to the inner side of the rotation hole. Thus, by rotating the rotating rod in the rotating hole, the first rotating plate and the second rotating plate can be relatively rotated, so that the protective nets at the outer ends of the first rotating plate and the second rotating plate can be relatively rotated, so that the overall angle of the protective structure can be adjusted as needed.

[0014] A further improvement is that the blocking unit includes a guardrail, a fixed plate, a threaded rod, a rotating handle, a movable splint and a fixed splint, the guardrail is connected to the left end of the protective net, the fixed plate is fixedly connected to the middle position of the front and rear ends of the right side of the guardrail, the threaded rod is connected to the inside of the fixed plate, the fixed splint is fixedly connected to the right side of the guardrail at one end of the fixed plate close to the center of the guardrail, the rotating handle is fixedly connected to one end of the threaded rod away from the fixed splint, and the movable splint is fixedly connected to one end of the threaded rod away from the rotating handle.

[0015] A further improvement is that a threaded hole is provided in the middle of the fixed plate, the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole, and the side of the movable clamping plate away from the threaded rod abuts against the outer side of the protective net. Thus, after placing the guardrail on the left end of the protective net, the rotating handle is turned to drive the threaded rod to rotate, so that one end of the movable clamping plate is moved to the outer side of the rotating handle, so that the protective net is clamped and fixed between the movable clamping plate and the fixed clamping plate, so that the guardrail can be fixed to the left end of the protective net, preventing pedestrians from mistakenly entering the protective device.

[0016] A further improvement is that the lower sides of the straight connecting rod, the first rotating plate and the second rotating plate are fixedly connected with anti-skid pads. Therefore, after the protective structure is fixed to the left end of the shot blasting machine body, the rubber pads on the lower sides of the straight connecting rod, the first rotating plate and the second rotating plate contact the ground, so that the protective structure can be more firmly fixed to the left end of the shot blasting machine body.

[0017] In summary, the present application discloses a protective device for a shot blasting machine.

[0018] The technical solution allows the first rotating plate and the second rotating plate to rotate relative to each other by rotating the second rotating plate around the rotating rod, so that the protective nets at the outer ends of the first rotating plate and the second rotating plate can rotate relative to each other, so that the overall angle of the protective structure can be adjusted as needed.

[0019] Furthermore, after placing the guardrail at the left end of the protective net, the rotating handle is turned to drive the threaded rod to rotate, so that one end of the movable clamp is moved to the outside of the rotating handle, so that the protective net is clamped and fixed between the movable clamp and the fixed clamp, so that the guardrail can be fixed to the left end of the protective net to prevent pedestrians from accidentally entering the protective device.
