Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a fixed-distance feeding system of a roller conveying system of a shot blasting machine. Background Art

[0002] At present, for the shot blasting and spraying equipment of steel pipes, especially small-diameter steel pipes, part of them adopt special vertebral roller equipment or roller-type equipment for steel structure. The special vertebral roller equipment has a narrow application range. If the workpieces of other shapes and structures need to be shot blasted or sprayed, other equipment needs to be selected again. If roller-type equipment for steel structure is used to clean steel pipes, the shot blasting and spraying effects are often poor due to the mutual blocking of steel pipes caused by the rolling of steel pipes.

[0003] Adding retaining rings on the roller shaft can prevent the steel pipes from blocking each other, but how to evenly distribute the steel pipes within the retaining rings on the roller shaft is also a problem that needs to be solved: manual single-pipe transportation increases the workload, and manual multiple-pipe loading cannot evenly distribute the steel pipes. Utility Model Content

[0004] The purpose of the utility model is to provide a fixed-distance feeding system for a roller conveying system of a shot blasting machine, so as to solve the problems raised in the above-mentioned background technology.

A plurality of block rotating shafts are rotatably connected between the two oblique rods. The spacing movable block is sleeved on the rod body of the block rotating shaft, and the spacing movable block is between the two oblique rods. Blocks are fixed in the middle of the top surfaces of the two oblique rods for blocking the steel pipe. The feeding wing is an "L"-shaped plate structure. The feeding wing is hinged between the two oblique rods. The material displacing cylinder is fixed on the surface of a vertical pole, and the material displacing cylinder is aligned with the feeding wing.

[0007] Preferably, a protrusion is integrally formed on the surface of the fixed-distance movable stopper for blocking the steel pipe, and a through hole is opened on the surface of the fixed-distance movable stopper for inserting the stopper shaft.

[0008] Preferably, baffles are fixed on the surfaces of the two oblique rods, the two groups of baffles are staggered, the baffles are used to limit the swing amplitude of the fixed-distance movable baffles, and the multiple fixed-distance movable baffles are staggered in pairs.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The fixed-distance feeding system of the roller conveyor system of the shot blasting machine proposed in the utility model adopts a roller type steel structure equipment cleaning equipment, which does not need to add new equipment and reduces cost expenditure. The steel pipes can be distributed at a fixed distance and quantity to prevent mutual obstruction between steel pipes during shot blasting and spraying.

DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 6 The utility model provides a technical solution: a fixed-distance feeding system of a roller conveyor system of a shot blasting machine, including a material-dividing and distance-fixing system 1, wherein a plurality of the material-dividing and distance-fixing systems 1 are provided, a connecting frame is fixed between two adjacent material-dividing and distance-fixing systems 1, a propulsion cylinder 2 is fixed on the surface of the connecting frame, the propulsion cylinder 2 is used to push the fixed-distance feeding system 3 to slide, a plurality of the fixed-distance feeding systems 3 are provided, the fixed-distance feeding system 3 is located between two adjacent material-dividing and distance-fixing systems 1, and a roller system 4 is provided at one end of the material-dividing and distance-fixing system 1.

[0022] The material shifting and spacing system is composed of a fixed-distance block 101, a fixed-distance movable block 102, a block rotating shaft 103, a wing block 104, a feeding wing 105, a block 106, a material rack 107, and a material shifting cylinder 108. When a certain amount of steel pipes are placed on the upper end of the material rack 107 at a certain angle, they are blocked by the block 106, and the material shifting cylinder 108 extends to drive the feeding wing 105 to move. The feeding wing 105 lifts a steel pipe over the block 106 and rolls down along the material rack. When the first steel pipe rolls to the fixed-distance block 101, due to the center of gravity of the fixed-distance movable block 102, it rotates along the block rotating shaft 103 as the center of the circle, and its rear is upturned, and the front with the block is located at the material rack. Below the plane on the rack, the steel pipe rolls to the fixed-distance movable stopper 102, presses over the upturned part behind the fixed-distance movable stopper 102, and reaches the position of the fixed-distance movable stopper 101. The steel pipe presses the rear of the fixed-distance movable stopper 102, and the block in front of the fixed-distance movable stopper 102 is upturned to expose the upper plane of the rack 107. When the second steel pipe rolls down along the first rolling method to the point where the block in front of the first fixed-distance movable stopper 102 is upturned to expose the upper plane of the rack 107, the other steel pipes roll down and stop in turn.

[0023] A wing stopper 104 is provided below the front end of the fixed-distance movable stopper 102 to prevent the movable stopper 102 from flipping and causing the fixed-distance movable stopper 102 to deviate due to the rolling of the steel pipe. The fixed-distance movable stopper 102 is distributed in the rack 107 in order from left to right to avoid interference between the movable fixed-distance movable stops 102.

[0024] The fixed-distance feeding system is composed of a toothed fixed-distance block 301, a crossbeam 302, a column 303, a bearing 304, a rotating shaft 305, a shifting wing 306, a material lifting cylinder 307, a frame 308, a roller 309, and a guide rail 310. When the material-shifting and spacing system 1 has distributed a certain amount of steel pipes at a certain distance, the propulsion cylinder 2 drives the frame 308 to withdraw from the bottom roller 309 of the frame 308 along the guide rail 310 to the bottom of the steel pipes distributed at a certain distance by the material-shifting and spacing system 1, and the lifting cylinder 307 contracts to drive the rotating shaft 305 connected to the shifting wing 306 to rotate along the bearings 304 at both ends, and the toothed spacing block 301 above the crossbeam 302 fixed by the column 303 on the rotating shaft 305 stands up together. Since the toothed spacing block 301 is the same as the steel pipe spacing on the material-shifting and spacing system 1, and the toothed spacing block 301 lifts the steel pipe when standing up, so that the steel pipe is higher than the front of the material-shifting and spacing system 1.

[0025] 2. The thrust cylinder pushes out the fixed-distance feeding system 3, so that the fixed-distance feeding system 3 reaches the inside of the roller system 4 (the common structure is not introduced). Since 3. The fixed-distance feeding is higher than the roller shaft of the roller system 4 and the retaining ring on the roller shaft, the steel pipe can pass smoothly. Due to the stroke of the lifting cylinder 307, the steel pipe on the fixed-distance feeding system 3 just reaches the top of the roller shaft evenly. The lifting cylinder 307 of the fixed-distance feeding system 3 is pushed out, driving the rotating shaft 305 connected to the wing 306 to rotate along the bearings 304 at both ends. The toothed fixed-distance block 301 above the crossbeam 302 fixed by the column 303 on the rotating shaft 305 falls together, and the steel pipe just falls between the retaining rings on the roller shaft. The operation of the roller drives the steel pipe to move, and the equipment performs shot blasting and spraying on the steel pipe.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
