Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a structure for a shot blasting machine feed valve. Background Technology

[0002] A shot blasting machine is a mechanical device that uses a high-speed rotating impeller to propel shot (such as steel shot, casting shot, etc.) onto the surface of a workpiece at a certain speed for cleaning, strengthening, or altering its surface condition. It plays a vital role in industries such as metal processing, casting, forging, and heat treatment. As a key component of a shot blasting machine, the structure of the feed valve has a decisive impact on the uniformity and efficiency of shot feeding, as well as the overall performance of the machine.

[0003] Especially during the shot blasting process, this core step requires the feed valve to stably and evenly control the flow rate of the shot to ensure the uniformity and consistency of the shot blasting process. However, existing shot blasting machine feed valve devices have gradually revealed a series of obvious limitations and technical problems when handling shot of specific shapes, materials, or requirements. Specifically, although utility model patent CN217225124U discloses a feed valve device for shot blasting machines that solves the problem of uneven shot feeding caused by the lack of an anti-clogging mechanism in the shot storage hopper of existing shot blasting machines, the valve plate is opened by the rotation of the shot throwing worm gear. Simultaneously, the valve plate moves upward under the drive of the threaded sleeve, which rotates circumferentially under the action of the sleeve to stir the discharge port of the storage hopper. This achieves more timely valve plate closing and opening, more uniform shot blasting, and improved usability of the shot blasting machine.

[0004] However, existing shot blasting machines, after feeding, do not easily separate the material from the shot, directly leading to a reduction in the overall effectiveness of the machine. This is because the mixing of material and shot not only increases the difficulty of subsequent processing but may also cause unnecessary damage to the material surface, affecting product quality and appearance. More seriously, if the shot is not separated from the material in a timely and effective manner, it may interfere with the continuous operation of the shot blasting machine, increasing equipment maintenance costs and risks. Therefore, to address this deficiency in existing technology, we urgently need an innovative shot blasting machine feeding valve structure to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding valve structure for a shot blasting machine, which solves the problem in the prior art that after feeding, it is not easy to separate the material from the shot, which directly leads to a reduction in the overall performance of the shot blasting machine.

[0006] To achieve the above objectives, this utility model provides a feed valve structure for a shot blasting machine, including a shot blasting machine.

[0007] It also includes a discharge frame connected to the bottom of the shot blasting machine, and base plates fixedly connected to both sides of the shot blasting machine, with pull-out plates slidably connected to both sides of the bottom of the discharge frame.

[0008] A side frame is fixedly connected to one side of the base plate, and a drive motor is fixedly connected to one side of the outer wall of the side frame by bolts. A double screw is rotatably connected to the inner side of the side frame, and both ends of the double screw are connected to nut seats by threaded engagement. One side of each of the two nut seats is fixedly connected to one side of each of the two pull-out plates. An inclined filter plate is fixedly connected between the lower parts of the two base plates, and a bottom frame that slides with the two base plates is provided at the bottom of the filter plate. A collection frame is fixedly connected to one side of the outlet of the filter plate.

[0009] One end of each of the two pull-out plates passes through the two bottom plates in sequence via side grooves, and sliders are fixedly connected to both sides of the bottom of the discharge frame. Both sliders are slidably connected to the top of the two pull-out plates via sliding grooves.

[0010] Each of the two nut seats has a protrusion fixedly connected to one side, and both protrusions are slidably connected to the inner wall of the side frame through a movable groove.

[0011] One end of the bidirectional screw is rotatably connected to the inner wall of the side frame via a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the side frame via a bearing sleeve.

[0012] The bottom frame has sliding blocks fixedly connected to both sides, and the two sliding blocks are slidably connected to the two bottom plates through sliding grooves.

[0013] In this configuration, the two sliding blocks are fitted with clearances to the two sliding grooves.

[0014] This utility model discloses a discharge valve structure for a shot blasting machine. A drive motor rotates a bidirectional screw, and through the transmission of a nut seat and a pull-out plate, the discharge frame automatically opens and closes. This not only simplifies operation but also significantly improves discharge efficiency, solving the problem of inconvenient discharge in existing technologies. Secondly, the ingenious inclined filter plate design achieves separation of the shot and the workpiece. The shot falls through the filter plate into the bottom frame, while the workpiece rolls into the collection frame. This separation process is natural and efficient, requiring no additional manual operation or equipment assistance, greatly reducing the difficulty and cost of subsequent processing. Precise control of the drive motor and bidirectional screw ensures timely and accurate opening and closing of the discharge frame, guaranteeing the continuous and stable operation of the shot blasting machine. Simultaneously, the maintenance cost of this structure is relatively low, providing strong support for the long-term use of the shot blasting machine. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figure 1-5 ,

[0024] A feed valve structure for a shot blasting machine, comprising a shot blasting machine 1,

[0025] It also includes a discharge frame 2 connected to the bottom of the shot blasting machine 1. After the shot blasting machine 1 finishes processing, the workpiece and shot are discharged through the discharge frame 2 and enter the subsequent separation process. The bottom plates 18 are fixedly connected to both sides of the shot blasting machine 1, and the bottom sides of the discharge frame 2 are slidably connected to the pull plates 3. The pull plates 3 are moved to open or close the bottom outlet of the discharge frame 2 to control the discharge of the workpiece and shot.

[0026] A side frame 11 is fixedly connected to one side of the base plate 18, and a drive motor 12 is fixedly connected to one side of the outer wall of the side frame 11 by bolts. A bidirectional screw 13 is rotatably connected to the inner side of the side frame 11, and both ends of the bidirectional screw 13 are threadedly connected to nut seats 14. One side of each of the two nut seats 14 is fixedly connected to one side of each of the two pull-out plates 3. An inclined filter plate 7 is fixedly connected between the lower parts of the two base plates 18. By using the inclined design and the pore structure, the workpiece and the sand shot are naturally separated under the action of gravity. The workpiece rolls into the collection frame 17, while the sand shot falls into the bottom frame 8 through the pores. The bottom of the filter plate 7 is provided with a bottom frame 8 that is slidably connected to the two base plates 18, and a collection frame 17 is fixedly connected to one side of the outlet of the filter plate 7.

[0027] Furthermore, one end of each of the two pull-out plates 3 passes through the two bottom plates 18 sequentially via the side grooves 6, and sliders 4 are fixedly connected to both sides of the bottom of the discharge frame 2. Both sliders 4 are slidably connected to the tops of the two pull-out plates 3 via the sliding grooves 5. When the drive motor 12 starts and drives the bidirectional screw 13 to rotate, the nut seat 14 drives the pull-out plates 3 to move. At this time, one end of the pull-out plate 3 slides in the bottom plate 18 via the side grooves 6, while its top slides in the sliding grooves 5 via the sliders 4. This ensures the stability and accuracy of the movement of the pull-out plate 3, achieving a smooth and stable movement of the pull-out plate 3. It avoids the pull-out plate 3 from getting stuck or shifting during the movement, thereby ensuring the smooth opening and closing of the bottom outlet of the discharge frame 2.

[0028] Furthermore, each of the two nut seats 14 is fixedly connected to one side with a protrusion 15, and both protrusions 15 are slidably connected to the inner wall of the side frame 11 through the movable groove 16. When the nut seat 14 moves with the rotation of the bidirectional screw 13, the protrusion 15 slides in the movable groove 16, which guides and restricts the movement of the nut seat 14, achieving the effect of stable movement of the nut seat 14 and preventing the nut seat 14 from rotating or deviating during the movement, thereby ensuring the stability of its connection with the pull plate 3 and the accuracy of transmission.

[0029] Furthermore, one end of the bidirectional screw 13 is rotatably connected to the inner wall of the side frame 11 via a rotating shaft, and the other end of the bidirectional screw 13 passes through the side wall of the side frame 11 via a bearing sleeve.

[0030] Furthermore, sliding blocks 9 are fixedly connected to both sides of the bottom frame 8, and the two sliding blocks 9 are slidably connected to the two bottom plates 18 respectively through sliding grooves 10. When the sand shot falls into the bottom frame 8 through the filter plate 7, the bottom frame 8 may move due to the weight of the sand shot. At this time, the sliding blocks 9 slide in the sliding grooves 10, which guides and restricts the movement of the bottom frame 8, achieving the effect of stable movement of the bottom frame 8 and preventing the bottom frame 8 from shifting or tilting during the movement, thereby ensuring the smooth collection of sand shot and the stability of the bottom frame 8.

[0031] Furthermore, the two sliding blocks 9 are respectively in clearance fit with the two sliding grooves 10.

[0032] In summary:

[0033] During the normal operation of shot blasting machine 1, the high-speed rotating impeller first propels the shot onto the surface of the workpiece at a certain speed to clean, strengthen, or change its surface condition. After processing, the workpiece and shot in shot blasting machine 1 need to be unloaded. The drive motor 12, which is bolted to one side of the outer wall of the side frame 11, is then started. The drive motor 12 drives the bidirectional screw 13, which is rotatably connected to the inner side of the side frame 11, to start rotating. Both ends of the bidirectional screw 13 are threadedly connected to nut seats 14. As the bidirectional screw 13 rotates, the two nut seats 14 move simultaneously in opposite directions. One side of each of the two nut seats 14 is fixedly connected to a protrusion 15. The protrusion 15 slides in the movable groove 16, guiding and restricting the movement of the nut seats 14, ensuring stable movement and preventing rotation or deviation during movement. Since the two nut seats 14 are fixedly connected to one side of the two pull plates 3 respectively, the two pull plates 3 will also move simultaneously in opposite directions as the nut seats 14 move. One end of each of the two pull-out plates 3 passes through the two bottom plates 18 sequentially via side grooves 6, and sliders 4 are fixedly connected to both sides of the bottom of the discharge frame 2. Both sliders 4 are slidably connected to the tops of the two pull-out plates 3 via sliding grooves 5. When the pull-out plate 3 moves, one end slides in the bottom plate 18 via the side groove 6, while its top slides in the sliding groove 5 via the slider 4, ensuring the stability and accuracy of the pull-out plate 3's movement. This achieves a smooth and stable movement of the pull-out plate 3, avoiding any jamming or deviation during movement. In this way, the movement of the pull-out plate 3 smoothly opens the bottom outlet of the discharge frame 2. At this time, the workpiece and shot in the shot blasting machine 1 will be discharged along the opening of the discharge frame 2 and fall onto the inclined filter plate 7. The inclined design of the filter plate 7 allows the workpiece and shot to separate naturally under gravity. Due to its small size, the shot will fall into the bottom frame 8 through the holes of the filter plate 7. Sliding blocks 9 are fixedly connected to both sides of the bottom frame 8. Each sliding block 9 is slidably connected to one of the two bottom plates 18 via sliding grooves 10, with a clearance fit between the two sliding blocks 9 and the two sliding grooves 10. When sand pellets fall into the bottom frame 8, the frame may move due to the weight of the pellets. At this time, the sliding blocks 9 slide in the sliding grooves 10, guiding and restricting the movement of the bottom frame 8, achieving stable movement and preventing deviation or tilting during movement. This ensures smooth collection of the sand pellets and the stability of the bottom frame 8. The workpiece, due to its larger size, will roll into the collection frame 17 fixedly connected to one side of the filter plate 7 outlet. This achieves effective separation of the sand pellets and the workpiece. Through the cooperation of the drive motor 12, the bidirectional screw 13, the nut seat 14, and the pull plate 3, the bottom outlet of the discharge frame 2 is automatically opened and closed, simplifying operation and improving feeding efficiency.The inclined design of the filter plate 7, along with the bottom frame 8 and the collection frame 17, effectively separates the shot from the workpiece, reducing the difficulty and cost of subsequent processing and preventing damage to the material surface caused by the mixing of materials and shot. The cooperation between the protrusion 15 and the movable groove 16 ensures the stable movement of the nut seat 14, thereby ensuring the connection stability and transmission accuracy between the pull plate 3 and the nut seat 14. The cooperation between the slider 4 and the slide groove 5 ensures the stability and accuracy of the movement of the pull plate 3, preventing jamming or offset during movement.

[0034] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
