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] Shot blasting machines are surface treatment equipment widely used in industries such as machinery manufacturing, ship repair, and steel structures. Their working principle involves using a high-speed rotating impeller to violently propel metal shot (such as steel shot, wire cut shot, etc.) or other abrasives onto the workpiece surface. Through impact and abrasion, they effectively remove oxide scale, rust, welding slag, old paint layers, and other contaminants from the workpiece surface. Simultaneously, they strengthen the workpiece surface and increase its roughness, thereby improving the adhesion of subsequent coatings.

[0003] In existing technology, shot blasting machines typically include a closed shot blasting chamber. During operation, the door is closed to prevent abrasive flying and injury, and to reduce dust leakage. Chinese utility model patent CN222570421U discloses a shot blasting machine with protective features. This equipment achieves the enclosure of the shot blasting chamber by setting a door, which improves operational safety to a certain extent.

[0004] However, practical experience has revealed significant deficiencies in the door structure of such shot blasting machines when internal maintenance, replacement of wear parts, or cleaning of accumulated abrasive are required. Specifically, most existing doors employ simple hinge connections and manual closing, lacking a mechanical locking mechanism to effectively prevent accidental closure during equipment downtime for maintenance. When maintenance personnel are working inside the shot blasting chamber, if unnoticed personnel accidentally operate the door, or if the equipment is bumped by other objects due to confined space, the door can easily close suddenly. This could not only injure maintenance personnel, causing serious personal injury accidents, but the massive impact of the heavy door closing abruptly could also damage the door itself and the hinge structure, affecting the equipment's lifespan and sealing performance. Utility Model Content

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

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shot blasting machine with protective function, comprising a machine body, a door installed on the outer surface of the machine body via a hinge, a shot blasting machine installed on the left side of the machine body, the output end of the shot blasting machine penetrating the machine body, and a protective component and a transmission component provided on the outer surface of the machine body;

[0007] The protective components include:

[0008] Connecting plate, the connecting plate is used to rotate synchronously with the box door;

[0009] Limiting groove: The limiting groove is used to limit the movement of the connecting plate and the door in one direction.

[0010] Limit plate, the limit plate is used to work with the limit groove to achieve the limit.

[0011] Preferably, the connecting plate is fixed to the top of the door, the axis of the connecting plate and the axis of the hinge are on the same horizontal line, a circular plate is fixed to the top of the connecting plate, and a limit groove is formed on the outer surface of the circular plate. A connecting block is fixed to the top of the body, and a cavity is formed inside the connecting block. A rotating plate is rotatably connected to the inner wall of the cavity. A movable hole is formed on the outer surface of the rotating plate, and a stop rod abuts against the inner wall of the movable hole. A through hole is formed on the outer surface of the connecting block, and the end of the stop rod away from the movable hole passes through the through hole. The end of the contact rod away from the movable hole is rotatably connected to a limiting plate. A stabilizing plate is fixed to the outer surface of the connecting block, and a spring is fixed to the outer surface of the stabilizing plate. The end of the spring away from the stabilizing plate is fixed to the outer surface of the limiting plate. The end of the limiting plate away from the contact rod abuts against the inner wall of the limiting groove. When the door rotates, the connecting plate and the circular plate rotate synchronously. The limiting plate reciprocates into the limiting groove through the spring, allowing the door to rotate normally forward. The other side of the limiting plate abuts against the inner wall of the limiting groove, preventing the circular plate, the connecting plate, and the door from reversing, thereby preventing the door from closing accidentally.

[0012] Preferably, the transmission assembly includes a short rod fixed to the top of the rotating plate. The top of the short rod passes through a connecting block, and the short rod is rotatably connected to the connecting block. A worm gear is fixed to the end of the short rod away from the rotating plate, and the worm gear is rotatably connected to the top of the connecting block. A connecting frame is fixed to the top of the connecting block, and a worm is rotatably connected to the inner side of the connecting frame. A second motor is fixed to the outer surface of the connecting frame, and the output shaft of the second motor passes through the connecting frame. A groove is formed on the outer surface of the worm, and the output shaft of the second motor extends into the groove. A movable plate is fixed to the output shaft of the second motor, and a movable plate is slidably connected to the output shaft of the second motor. A fourth spring is fixed to the outer surface of the movable plate, and the end of the fourth spring away from the movable plate is fixed to the outer surface of the movable plate. A protrusion is fixed to the side of the movable plate away from the fourth spring. A linkage groove is formed on the inner wall of the groove. When it is necessary to close the door, the second motor is started, and the first movable plate, the second movable plate, and the protrusion rotate. The outer surface of the protrusion contacts the inner wall of the linkage groove, pushing the worm, worm wheel, and short rod to rotate synchronously, causing the rotating plate and movable hole to rotate. The inner wall of the movable hole contacts the abutment rod, pushing the limit plate to move linearly and disengage from the limit groove, at which point the door can be closed normally.

[0013] Preferably, a motor is fixed to the top of the machine body, the output shaft of the motor passes through the machine body, and a hook is fixed to the bottom of the output shaft of the motor. When the motor is started, it can drive the workpiece to rotate synchronously, which facilitates all-round grinding work.

[0014] Preferably, a protective plate is slidably connected to the inner wall of the machine body, a damper is fixed to the outer surface of the protective plate, and the end of the damper away from the protective plate is fixed to the inner wall of the machine body. A spring is fixed to the outer surface of the protective plate, and the end of the spring away from the protective plate is fixed to the inner wall of the machine body. A sieve plate is installed on the outer surface of the protective plate, a spring is fixed to the top of the sieve plate, a fixing plate is fixed to the top of the spring, and the top of the spring is fixed to the outer surface of the protective plate. A vibrating motor is fixed to the bottom of the sieve plate. A discharge port is opened on the left side of the machine body, and the left end of the sieve plate passes through the discharge port. When the vibrating motor is turned on, screening is performed, and the shot is discharged and recycled from the discharge port, while the waste falls into the interior of the machine body. At the same time, when the shot impacts the protective plate, the impact on the machine body is effectively reduced by the buffering effect of the spring and the damper.

[0015] Preferably, the cross-section of the end of the limiting plate away from the abutment rod is triangular. When the limiting plate enters the limiting groove, the circular plate can only rotate forward. When the limiting plate leaves the limiting groove, the circular plate can rotate in reverse normally.

[0016] Preferably, the protrusion and the linkage groove are both hemispherical. When the worm can no longer rotate, slippage can occur between the protrusion and the linkage groove, which will not affect the normal operation of the second motor.

[0017] Compared with the prior art, this utility model provides a shot blasting machine with protective function, which has the following beneficial effects:

[0018] 1. This shot blasting machine with protective function, through the set protective components, when the internal maintenance and cleaning of the machine body is required, the door is opened, so that the connecting plate and the circular plate rotate synchronously, and the limit plate enters the limit groove. Through the spring three, the door and the connecting plate can only rotate forward and not reverse, so as to prevent the door from closing accidentally and protect the maintenance personnel.

[0019] 2. This shot blasting machine with protective function, through its transmission components, activates motor two when the chamber door needs to be closed. This motor rotates movable plates one and two, along with the protrusion, causing the worm gear, worm wheel, and short rod to rotate synchronously. The rotating plate and movable hole also rotate. The inner wall of the movable hole contacts the abutment rod, pushing the limit plate linearly and disengaging it from the limit groove, allowing the chamber door to close normally. When the worm gear cannot rotate, slippage occurs between the protrusion and the linkage groove, protecting motor two from stalling and burning out. To reset the limit plate, simply reverse motor two. Attached Figure Description

[0028] like Figures 1-7 As shown, this utility model provides a technical solution: a shot blasting machine with protective function, including a machine body 1, a door 2 installed on the outer surface of the machine body 1 via a hinge, a shot blasting machine 5 installed on the left side of the machine body 1, the output end of the shot blasting machine 5 penetrating the machine body 1, and a protective component 8 and a transmission component 9 provided on the outer surface of the machine body 1; the protective component 8 includes: a connecting plate 80, a circular plate 81, a limiting groove 82, a connecting block 83, a cavity 84, a rotating plate 85, a movable hole 86, a contact rod 87, a limiting plate 88, a stabilizing plate 89, a spring 800, and a through hole 801.

[0029] A connecting plate 80 is fixed to the top of the door 2. The axis of the connecting plate 80 is on the same horizontal line as the axis of the hinge. A circular plate 81 is fixed to the top of the connecting plate 80. A limit groove 82 is formed on the outer surface of the circular plate 81. A connecting block 83 is fixed to the top of the body 1. A cavity 84 is formed inside the connecting block 83. A rotating plate 85 is rotatably connected to the inner wall of the cavity 84. A movable hole 86 is formed on the outer surface of the rotating plate 85. A contact rod 87 abuts against the inner wall of the movable hole 86. A through hole 801 is formed on the outer surface of the connecting block 83. One end of the contact rod 87 away from the movable hole 86 passes through the through hole 801. The other end of the contact rod 87 away from the movable hole 86 is rotatably connected to a limit plate 88. A stabilizing plate 89 is fixed to the outer surface of the connecting block 83. A spring 800 is fixed to the outer surface of the stabilizing plate 89. One end of the 00 plate away from the stabilizing plate 89 is fixed to the outer surface of the limiting plate 88. The end of the limiting plate 88 away from the abutting rod 87 abuts against the inner wall of the limiting groove 82. The cross-section of the end of the limiting plate 88 away from the abutting rod 87 is triangular. When the door 2 rotates, the connecting plate 80 and the circular plate 81 rotate synchronously. At this time, the inner wall of the limiting groove 82 contacts the outer surface of the limiting plate 88, pushing the limiting plate 88 to flip and compress the spring 3 800. When the limiting plate 88 rotates to be parallel to the limiting groove 82, the spring 3 800 is released, pushing the limiting plate 88 to be inserted into the limiting groove 82. At this time, the door 2 and the connecting plate 80 can rotate normally in the forward direction, while the other side of the limiting plate 88 abuts against the inner wall of the limiting groove 82, preventing the circular plate 81, the connecting plate 80 and the door 2 from reversing, thereby preventing the door 2 from closing accidentally and playing a role in protecting maintenance personnel.

[0030] The transmission assembly 9 includes a short rod 90, which is fixed to the top of the rotating plate 85. The top of the short rod 90 passes through the connecting block 83, and the short rod 90 is rotatably connected to the connecting block 83. A worm gear 91 is fixed to the end of the short rod 90 away from the rotating plate 85. The worm gear 91 is rotatably connected to the top of the connecting block 83. A connecting frame 92 is fixed to the top of the connecting block 83. A worm gear 93 is rotatably connected to the inner side of the connecting frame 92. A second motor 94 is fixed to the outer surface of the connecting frame 92. The output shaft of the second motor 94 passes through the connecting frame 92. A groove 95 is formed on the outer surface of the worm gear 93, and the output shaft of the second motor 94 extends into the groove 95. Inside, the output shaft of motor 2 94 passes through and is fixed to movable plate 1 96. Movable plate 2 97 is slidably connected to the output shaft of motor 2 94. A spring 4 98 is fixed to the outer surface of movable plate 2 97. One end of spring 4 98 away from movable plate 2 97 is fixed to the outer surface of movable plate 1 96. A protrusion 99 is fixed to the side of movable plate 2 97 away from spring 4 98. A linkage groove 900 is formed on the inner wall of groove 95. Both protrusion 99 and linkage groove 900 are hemispherical. When the door 2 needs to be closed, motor 2 94 is started, driving movable plate 1 96, movable plate 2 97, and protrusion 99 to rotate. The outer surface of protrusion 99 contacts the inner wall of linkage groove 900, pushing worm 93, worm wheel 91, and short rod 90 to rotate synchronously, thereby causing rotating plate 85 and movable hole 86 to rotate. The inner wall of movable hole 86 contacts abutment rod 87, pushing limit plate 88 to move linearly and disengage from limit groove 82. At this time, door 2 can be closed normally. When the abutment rod 87 moves to its limit position, slippage occurs between the protrusion 99 and the linkage groove 900. Under the action of the spring 4 98, the movable plate 2 97 reciprocates, thereby protecting the motor 2 94 from stalling and burning out. To reset the limit plate 88, simply reverse the motor 2 94.

[0031] A motor 3 is fixed to the top of the machine body 1. The output shaft of the motor 3 passes through the machine body 1, and a hook 4 is fixed to the bottom of the output shaft of the motor 3. A protective plate 6 is slidably connected to the inner wall of the machine body 1. A damper 7 is fixed to the outer surface of the protective plate 6. The end of the damper 7 away from the protective plate 6 is fixed to the inner wall of the machine body 1. A spring 10 is fixed to the outer surface of the protective plate 6. The end of the spring 10 away from the protective plate 6 is fixed to the inner wall of the machine body 1. A screen plate 11 is installed on the outer surface of the protective plate 6. A spring 12 is fixed to the top of the screen plate 11. A fixing plate 13 is fixed to the top of the spring 12. The top of the spring 12 is fixed to the outer surface of the protective plate 6. A vibration motor 14 is fixed to the bottom of the screen plate 11. A discharge port 15 is opened on the left side of the machine body 1. The left end of the screen plate 11 passes through the discharge port 15. When the shot blasting machine 5 and the motor 3 are started, the workpiece begins to rotate to achieve all-round grinding. The generated waste and projectiles fall onto the screen plate 11. At this time, the vibrating motor 14 is turned on for screening: the projectiles are discharged and recycled from the discharge port 15, while the waste falls into the machine body 1, thus achieving the separation and collection of the projectiles and waste. At the same time, when the projectiles impact the protective plate 6, the impact on the machine body 1 is effectively reduced by the buffering effect of the spring 10 and the damper 7.

[0032] When processing is required, the workpiece is hung on hook 4. Turning on shot blasting machine 5 and motor 3 causes the workpiece to rotate, achieving all-around grinding. Simultaneously, waste chips and shot fall onto the outer surface of screen plate 11. Turning on vibrating motor 14 initiates screening; shot is discharged through discharge port 15, and waste chips fall into the machine body 1 for collection and separation. Meanwhile, the shot impacts the outer surface of protective plate 6, where it is buffered by spring 10 and damper 7, preventing... To avoid impacting the machine body 1, when it is necessary to clean the waste inside the machine body 1, the door 2 can be opened to clean the inside of the machine body 1. At the same time, when the door 2 rotates, the connecting plate 80 and the circular plate 81 rotate synchronously. At this time, the inner wall of the limiting groove 82 abuts against the outer surface of the limiting plate 88, and the limiting plate 88 flips over. At the same time, the spring 3 800 is compressed. When the position of the limiting plate 88 is parallel to the limiting groove 82, the spring 3 800 is released, which can drive the limiting plate 88 into the limiting groove 82 without affecting the door 2 and the connecting plate 80. When the device rotates normally in the forward direction, the outer surface of the limit plate 88 on the other side abuts against the inner wall of the limit groove 82, preventing the circular plate 81, connecting plate 80, and door 2 from reversing, thus preventing the door 2 from closing properly and protecting maintenance personnel. When it is necessary to close the door 2, the second motor 94 is turned on, which synchronously drives the first movable plate 96, the second movable plate 97, and the protrusion 99 to rotate. At this time, the outer surface of the protrusion 99 abuts against the inner wall of the linkage groove 900, which causes the worm 93, worm wheel 91, and short rod 90 to rotate synchronously. At this time, the rotating plate 85 drives... The movable hole 86 rotates synchronously. At this time, the inner wall of the movable hole 86 abuts against the outer surface of the abutment rod 87, which allows the limit plate 88 to move linearly away from the limit groove 82. At this time, the box door 2 can be closed normally. At the same time, when the abutment rod 87 can no longer move, the protrusion 99 slips between the linkage groove 900. Through the spring 4 98, the movable plate 2 97 can be driven to rotate back and forth without affecting the normal operation of the motor 2 94 and avoiding the burnout of the motor 2 94. When the limit plate 88 needs to be reset, the motor 2 94 can be turned on to reverse.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
