Description

Technical Field

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

[0002] In industrial production, tracked shot blasting machines are widely used for surface treatment of metal workpieces, using high-speed shot blasting to clean and strengthen the workpiece surface.

[0003] However, existing tracked shot blasting equipment has revealed some problems that urgently need to be solved in practical applications:

[0004] Traditional tracked shot blasting machines have recessed areas in their track design, where workpieces tend to accumulate during processing. This accumulation not only leads to uneven processing time, affecting the consistency of surface treatment results, but also prolongs the processing cycle of the entire batch of workpieces, reducing production efficiency. During the workpiece discharge process, a large amount of shot blasting residue remains on the workpiece surface. If this residue is not effectively cleaned, it will interfere with subsequent workpiece surface treatment.

[0005] Therefore, a tracked continuous shot blasting device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a tracked continuous shot blasting device in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A tracked continuous shot blasting device includes a housing, on which a steel shot lifting and spraying mechanism is provided. Limiting posts are provided on both side walls of the housing. A continuous drive mechanism is provided on the surface of the housing. Tracks are fitted onto the rotating part of the continuous drive mechanism and the limiting posts. An auxiliary turning component is provided at the concave part of the track and two sets of limiting posts. A discharge component is provided on the front side wall of the housing to discharge the shot-blasted workpiece.

[0009] Furthermore, the continuous drive mechanism includes two sets of conveyor shafts rotatably inserted into the side walls of the chassis, and a first motor is fixedly installed on the rear side wall of the chassis. A single-groove synchronous pulley is fixedly sleeved on the end of one set of conveyor shafts and the output end of the first motor, and a double-groove synchronous pulley is fixedly sleeved on the end of the other set of conveyor shafts. A synchronous belt is sleeved on the double-groove synchronous pulley and the two sets of conveyor shafts so as to achieve synchronous rotation driven by the first motor and start the track operation.

[0010] Furthermore, the auxiliary flipping assembly includes a rotating shaft that is rotatably inserted into two sets of limiting posts, wherein a second motor is fixedly installed on the end face of one set of limiting posts, and the output end of the second motor is fixedly connected to the end of the rotating shaft. A rubber roller is fixedly sleeved on the surface of the rotating shaft and inside the housing.

[0011] Furthermore, the discharge assembly includes a discharge hopper fixedly installed on the front side wall of the machine and located at the hopper opening. Two sets of side plates are fixedly installed on the top surface of the discharge hopper, and conveying rollers are rotatably inserted into the two sets of side plates. A third motor is fixedly installed on the front side wall of the front discharge hopper, and the output end of the third motor is connected to the end of the conveying rollers. A mesh conveyor belt is sleeved on the surface of the two sets of conveying rollers.

[0012] Furthermore, a door is slidably installed on the front side wall of the chassis, and a hopper door is hingedly installed at the hopper opening on the front side of the chassis.

[0013] Furthermore, when performing surface treatment on metal workpieces, the rotation direction of the rubber rollers is opposite to the rotation direction of the conveyor shaft.

[0014] The beneficial effects of this utility model are as follows:

[0015] The continuous drive mechanism drives the track to operate continuously, and the workpiece is evenly distributed on the track and continuously passes through the shot blasting area to receive the blasting treatment of steel shot, which significantly improves production efficiency. The auxiliary turning component continuously turns the workpiece during the movement, avoiding the accumulation of workpieces in the concave parts of the track and ensuring that each workpiece is fully exposed to the shot blasting flow, thereby improving the uniformity and quality of surface treatment. The mesh conveyor belt helps to screen off residual shot, reduce shot carry-out, and reduce interference with subsequent processing. Attached Figure Description

[0026] like Figures 1 to 5As shown, a tracked continuous shot blasting device includes a housing 1, a shot lifting and spraying mechanism 2 on the housing 1, limit posts 11 on both side walls of the housing 1, a continuous drive mechanism 3 on the surface of the housing 1, and a track 4 fitted on the rotating part of the continuous drive mechanism 3 and the limit posts 11. An auxiliary turning component 5 is provided at the recess of the track 4 and on the two sets of limit posts 11. A discharge component 6 is provided on the front side wall of the housing 1 to discharge the shot-blasted workpiece. More specifically, the continuous drive mechanism 3 drives the track 4 to operate continuously, and the workpiece moves continuously on the track 4 through the shot blasting area to receive the shot blasting treatment. The auxiliary turning component 5 turns the workpieces accumulated in the concave part of the track 4 during the movement of the workpiece, so as to avoid the workpieces accumulating in the concave part of the track 4 and ensure that each workpiece can be fully exposed to the shot blasting flow. The shot blasting mechanism 2 realizes the blasting of steel shot, which is the existing technology and will not be described in detail here. This improves the uniformity and efficiency of surface treatment. The discharge component 6 is used to transport and discharge the workpiece laterally after the workpiece has been processed.

[0027] The continuous drive mechanism 3 includes two sets of conveyor shafts 301 rotatably connected to the side walls of the housing 1, and a first motor 302 is fixedly installed on the rear side wall of the housing 1. A single-groove synchronous pulley 303 is fixedly fitted at the end of one set of conveyor shafts 301 and the output end of the first motor 302, while a double-groove synchronous pulley 304 is fixedly fitted at the end of the other set of conveyor shafts 301. A synchronous belt 305 is fitted around the double-groove synchronous pulley 304 and both sets of conveyor shafts 301, so that they rotate synchronously driven by the first motor 302, starting the track 4. More specifically, the first motor 302 serves as the power source, driving the two sets of conveyor shafts 301 to rotate synchronously through the transmission of the single-groove synchronous pulley 303, the double-groove synchronous pulley 304, and the synchronous belt 305, thereby driving the track 4 to operate continuously, ensuring the stable movement of the workpiece on the track 4, and achieving continuous shot blasting.

[0028] The auxiliary flipping assembly 5 includes a rotating shaft 501 rotatably inserted into two sets of limiting posts 11. A second motor 503 is fixedly mounted on the end face of one set of limiting posts 11, and the output end of the second motor 503 is fixedly connected to the end of the rotating shaft 501. A rubber roller 502 is fixedly sleeved on the surface of the rotating shaft 501 and inside the housing 1. More specifically, the second motor 503 drives the rotating shaft 501 to rotate, and the rubber roller 502 rotates with the rotating shaft 501. During the movement of the track 4, the rubber roller 502 continuously flips the workpiece to prevent workpiece accumulation and ensure that the workpiece is evenly shot-loaded. At the same time, the rubber roller 502, made of rubber material, avoids damage to the surface of the workpiece.

[0029] The discharge assembly 6 includes a discharge hopper 601 fixedly installed on the front side wall of the housing 1 and located at the hopper opening. Two sets of side plates 602 are fixedly installed on the top surface of the discharge hopper 601, and conveying rollers 603 are rotatably inserted into the two sets of side plates 602. A third motor 604 is fixedly installed on the front side wall of the front discharge hopper 601. The output end of the third motor 604 is connected to the end of the conveying rollers 603. A mesh conveyor belt 605 is sleeved on the surface of the two sets of conveying rollers 603. More specifically, the third motor 604 drives the conveying rollers 603 to rotate, and the mesh conveyor belt 605 circulates under the drive of the conveying rollers 603. The workpieces that have completed shot blasting enter the surface of the mesh conveyor belt 605 from the conveyor belt 4 and are smoothly discharged under the action of the mesh conveyor belt 605. The mesh structure helps to screen off residual shot. The shot is then guided into the interior of the housing 1 through the discharge hopper 601, reducing the amount of shot carried out.

[0030] A door 12 is slidably installed on the front side wall of the chassis 1, and a hopper door 13 is hinged at the hopper opening on the front side of the chassis 1. More specifically, the design of the door 12 and the hopper door 13 facilitates the operator's entry into the chassis 1 for maintenance, cleaning, or adjustment when needed. The slidable door 12 and the hinged hopper door 13 ensure the equipment's airtightness while also being easy to open.

[0031] When performing surface treatment on metal workpieces, the rotation direction of the rubber roller 502 is opposite to the rotation direction of the conveyor shaft 301. More specifically, the rubber roller 502 rotates in the opposite direction to the conveyor shaft 301, so that while the track 4 drives the workpiece forward, the rubber roller 502 generates a reverse flipping action on the workpiece, enhancing the flipping effect, further preventing workpiece accumulation, and improving the uniformity of surface treatment.

[0032] In summary: The continuous drive mechanism 3 drives the track 4 to operate continuously, and the workpiece moves continuously on the track 4 through the shot blasting area to receive shot blasting treatment. The auxiliary turning component 5 continuously turns the workpieces accumulated in the concave part of the track 4 during the movement of the workpiece, so as to avoid the workpieces accumulating in the concave part of the track 4 and ensure that each workpiece can be fully exposed to the shot blasting flow. The shot blasting mechanism 2 realizes the blasting of steel shot, which is the existing technology and will not be described in detail here. This improves the uniformity and efficiency of surface treatment. The discharge component 6 is used to transport and discharge the workpiece laterally after the workpiece has been processed.
