Description

Technical Field

[0001] This application relates to the field of shot blasting equipment, and in particular to an automatic loading and unloading shot blasting production line. Background Technology

[0002] Shot blasting, a highly efficient and widely used surface treatment process, utilizes a shot blasting machine as its core equipment. This machine uses a high-speed rotating impeller to accelerate and propel shot onto the workpiece surface, removing sand, oxide scale, and burrs from castings, forgings, and other parts. It also improves the surface stress state and enhances fatigue strength. This equipment is widely used not only in ferrous metal industries such as cast steel and cast iron but is also a key piece of equipment for the post-processing of non-ferrous metal castings such as aluminum alloys and copper alloys, serving both quality inspection and surface finishing functions. In modern casting production, shot blasting has become an indispensable pre-treatment process before casting delivery, and its effectiveness directly affects the accuracy of subsequent non-destructive testing and the final quality of the product.

[0003] Although shot blasting technology itself is highly mature, the corresponding loading and unloading methods have long constrained the improvement of the overall automation level and further breakthroughs in production efficiency. In existing technologies, most shot blasting production lines still rely on manual loading and unloading of workpieces. This mode not only exposes operators to harsh environments such as noise and dust, resulting in high labor intensity and easy operational errors due to fatigue, but also leads to slow production cycles and low capacity, making it difficult to meet the needs of modern large-scale, continuous production. Summary of the Invention

[0004] In order to reduce labor intensity and improve production efficiency, this application provides an automatic loading and unloading shot blasting production line.

[0005] This application provides an automatic loading and unloading shot blasting production line, which adopts the following technical solution: An automatic loading and unloading shot blasting production line includes a shot blasting chamber. One end of the shot blasting chamber is provided with a loading port and the other end is provided with a unloading port. A loading conveyor belt and a vibrating loading cylinder are arranged sequentially on the side of the shot blasting chamber near the loading port, and the height of the output end of the loading conveyor belt is higher than the height of the input end of the vibrating loading cylinder. The shot blasting chamber is provided with a vibrating feed cylinder and a feed conveyor belt on the side near the feed inlet, and the height of the input end of the feed conveyor belt is lower than the height of the output end of the vibrating feed cylinder.

Each diverter nozzle is connected to the input end of the corresponding shot blasting machine body through a diverter pipe.

[0007] Optionally, the vibrating feed cylinder includes a second vibrating frame and a feed cylinder body mounted on the second vibrating frame. The input end of the feed cylinder body is connected to the feed port. The bottom of the feed cylinder body is provided with a first screen hole for steel shot to pass through. A sorting box is provided at the lower end of the feed cylinder body. A screen plate is provided inside the sorting box. The screen plate is provided with a second screen hole for blocking steel shot from passing through but allowing dust to pass through. The screen plate divides the sorting box into a steel shot sorting chamber and a dust sorting chamber from top to bottom. A steel shot discharge port is provided at the bottom of one side of the steel shot sorting chamber. The steel shot discharge port is connected to the feed port through a continuously inclined downward discharge channel.

[0008] Optionally, a dust filter is also included, which has an air inlet and an air outlet. The air inlet is connected to the shot blasting space through a main air inlet pipe, and an exhaust fan is connected to the air outlet.

[0009] Optionally, the vibrating feeding cylinder includes a first vibrating frame and a feeding cylinder body disposed on the first vibrating frame. The output end of the feeding cylinder body is connected to the feeding port. The feeding cylinder body is provided with a first suction pipe. The main air inlet pipe is provided with a multi-port connector. The end of the first suction pipe away from the feeding cylinder body is connected to the multi-port connector.

[0010] Optionally, the feeding cylinder body is provided with a second suction pipe, and the end of the second suction pipe away from the feeding cylinder body is connected to a multi-port connector.

[0011] Optionally, a third suction pipe is connected to one side of the discharge port, and the side of the third suction pipe away from the elevator is connected to a multi-port connector.

[0012] Optionally, a suction port is provided on one side of the dust sorting chamber, and a fourth suction pipe is connected to the suction port. The end of the fourth suction pipe away from the dust sorting chamber is connected to a multi-port connector.

[0013] Optionally, the output end of the induced draft fan is provided with an exhaust pipe, and a first blowing pipe is connected to the exhaust pipe. A blowing port is provided on one side of the steel shot sorting chamber, and the end of the first blowing pipe away from the exhaust pipe is connected to the blowing port.

[0014] Optionally, a second air blowing pipe is connected to the exhaust pipe, and an air blowing cover is provided at the end of the second air blowing pipe away from the exhaust pipe. The air blowing cover is located on one side of the material feeding conveyor belt, and multiple rectifier holes are provided on the side of the air blowing cover close to the material feeding conveyor belt.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a feeding conveyor belt and a vibrating feeding cylinder with height differences connecting them, as well as a vibrating unloading cylinder and an unloading conveyor belt, seamless, continuous, and automated transmission from the feeding end to the shot blasting chamber and then to the unloading end is achieved, completely replacing the traditional manual loading and unloading mode in shot blasting production. This layout not only greatly reduces the labor intensity of workers and avoids exposing personnel to harsh working environments, but more importantly, it ensures the stability and continuity of the production cycle, significantly improving the operating efficiency and capacity of the entire production line. The introduction of the vibrating feeding cylinder also provides a basis for the posture preparation of workpieces before they enter the shot blasting chamber, which is beneficial to the uniformity of subsequent shot blasting treatment.

[0016] 2. By integrating a sorting box onto the vibrating feed cylinder, the steel shot and dust carried by the shot-blasted workpiece are first coarsely separated through the first screen opening. The steel shot and fine dust then fall into the sorting box and are further finely separated through the second screen opening. This design achieves automatic and efficient separation of steel shot, dust, and processed workpieces. The separated pure steel shot is automatically returned to the elevator for recycling via the unloading channel, greatly reducing steel shot loss and lowering production costs. Simultaneously, this structure directly integrates the sorting function into the unloading station, allowing shot recovery to be completed during the workpiece unloading process. The process is compact, eliminating the need for additional independent sorting equipment and saving space and investment.

[0017] 3. A core negative pressure dust removal system was constructed by installing a dust filter connected to the shot blasting space. This system generates a stable airflow inside the shot blasting chamber, effectively capturing and sucking up the large amount of dust generated during the shot blasting process, providing a cleaner working environment for the process. Simultaneously, through the installation of the first, second, third, and fourth suction pipes and multi-port connectors, dust-laden airflow generated during the operation of the vibrating feeding cylinder, dust dispersed during the unloading process, dust introduced during the lifting process, and dust screened during the sorting process are respectively drawn into the dust filter for dust removal, thus achieving dust control throughout the entire material flow process and improving the cleanliness of the production line.

[0018] 4. By configuring the first air duct and air outlet, the clean, pressurized airflow after dust removal is guided back to the steel shot sorting chamber. This airflow is then blown from the side onto the falling steel shot and dust mixture, breaking the free settling state of the mixture and creating active, enhanced sorting conditions. First, the airflow effectively removes fine dust adhering to the surface of the steel shot, solving the adhesion problem caused by static electricity or oil. Second, the airflow forms a controllable turbulence within the steel shot sorting chamber. This turbulence has a two-way effect: on one hand, it gives some extremely fine, lightweight dust upward kinetic energy, enabling it to "return" and pass through the first screen holes back into the feed cylinder body space, ultimately being captured by the second suction duct; on the other hand, it accelerates the process of the remaining majority of dust passing downward through the second screen holes into the dust sorting chamber, preventing blockage or agitation during its descent, greatly improving screening efficiency and thoroughness. At the same time, this continuous airflow also provides forced cooling to the castings that have just undergone shot blasting and are at high temperatures, as well as the steel shot being sorted, accelerating the cooling process and shortening the production cycle. This design enables the internal reuse of the purified airflow, achieving multiple benefits by improving sorting efficiency, cooling efficiency, and production efficiency.

[0019] 5. By installing a second air duct and air hood, a portion of the purified airflow is guided to the unloading conveyor belt, realizing the utilization of high-pressure airflow waste energy. This allows for a final cleaning of the workpiece surface after shot blasting, removing any trace amounts of residual dust or steel shot debris, resulting in cleaner workpieces upon discharge. Furthermore, the airflow from the rectifier hole serves as a final cooling process, uniformly and continuously cooling the high-temperature castings during transport, ensuring that their temperature drops to a level safe for contact or direct processing by the end of the conveyor. This saves on subsequent independent cooling or cleaning processes, optimizes the production process, saves time and space costs, and enhances the intelligence and integration level of the production line.

[0030] The following combination Figures 1-9 This application will be described in further detail below.

[0031] Example: This application discloses an automated loading and unloading shot blasting production line. (Refer to...) Figure 1 and Figure 2An automatic loading and unloading shot blasting production line includes a loading conveyor belt 1, a vibrating loading cylinder 2, a shot blasting chamber 3, a vibrating unloading cylinder 4, and an unloading conveyor belt 5 arranged sequentially. The loading conveyor belt 1 is an inclined baffle conveyor belt; the output end of the loading conveyor belt 1 is higher than the input end of the vibrating loading cylinder 2; the shot blasting chamber 3 has a loading port 31 at one end near the vibrating loading cylinder 2, and a unloading port 32 at one end near the vibrating unloading cylinder 4; the unloading conveyor belt 5 is a downhill baffle conveyor belt; the input end of the unloading conveyor belt 5 is lower than the output end of the vibrating unloading cylinder 4.

[0032] By setting up a feeding conveyor belt 1 and a vibrating feeding cylinder 2 connected by a height difference, and a vibrating unloading cylinder 4 and an unloading conveyor belt 5, seamless, continuous, and automated transmission from the feeding end to the shot blasting chamber 3 and then to the unloading end is achieved, completely replacing the traditional manual loading and unloading mode in shot blasting production. This layout not only greatly reduces the labor intensity of workers and avoids personnel being exposed to harsh working environments, but more importantly, it ensures the stability and continuity of the production cycle, significantly improving the operating efficiency and capacity of the entire production line.

[0033] Reference Figures 1-3 The vibrating feed cylinder 2 includes a first vibrating frame 21 and a feed cylinder body 22 fixed on the first vibrating frame 21. The input end of the feed cylinder body 22 is connected to the output end of the feed conveyor belt 1, and the output end of the feed cylinder body 22 is connected to the feed port 31. The first vibrating frame 21 is driven to vibrate by a vibrating motor. In this way, the feed cylinder body 22 vibrates under the drive of the first vibrating frame 21, which can both sort and transport the workpiece, providing a basis for the posture sorting of the workpiece before entering the shot blasting chamber 3, which is beneficial to the uniformity of subsequent shot blasting; it can also have a certain crushing effect on the floating dust that may clump on the surface of the workpiece in the early stage of feeding.

[0034] Reference Figure 2 and Figures 4-6A plurality of shot blasting machine bodies 33 are fixed on the outer wall of the shot blasting chamber 3. The shot blasting chamber 3 has a shot blasting space 34 connecting the feed inlet 31 and the discharge inlet 32. The output end of the shot blasting machine body 33 extends into the shot blasting chamber 3 and communicates with the shot blasting space 34. A hoist 6 for lifting shot is provided on one side of the shot blasting chamber 3. The hoist 6 has a feed inlet 61 and a discharge outlet 62. The bottom end of the discharge outlet 62 is connected to a temporary storage bin 63. The bottom of the temporary storage bin 63 is fixedly connected to a diverter nozzle 631 corresponding to each shot blasting machine body 33. Each diverter nozzle 631 is connected to the input end of the corresponding shot blasting machine body 33 through a diverter pipe 632. In this embodiment, three shot blasting machine bodies 33 are provided. In this way, the shot can be lifted to the temporary storage bin 63 by the elevator 6 for temporary storage, and then accurately distributed to each shot blasting machine body 33 by the diverter 631 and the diverter pipe 632, thereby establishing a uniformly distributed centralized steel shot supply system, ensuring that each shot blasting machine body 33 can obtain a continuous and stable supply of steel shot, avoiding fluctuations in shot blasting intensity caused by insufficient or uneven shot supply, and thus ensuring the consistency of surface treatment effect of all workpieces.

[0035] Reference Figure 1 , Figure 2 and Figure 4 To ensure the overall cleanliness of the production line, a dust filter 7 is installed on one side of the shot blasting chamber 3. The dust filter 7 has an air inlet 71 and an air outlet 72. The air inlet 71 is connected to the shot blasting space 34 through the main air inlet pipe 73, and the air outlet 72 is connected to an induced draft fan 74. In this embodiment, the dust filter 7 is a cartridge dust collector. By setting up the dust filter 7 and connecting it to the shot blasting space 34, a core negative pressure dust removal system is constructed, which can generate a stable airflow inside the shot blasting chamber 3, effectively capturing and sucking up a large amount of dust generated during the shot blasting process, providing a cleaner working environment for the shot blasting process.

[0036] Reference Figure 1 , Figure 5 and Figure 7 The vibrating feed cylinder 4 includes a second vibrating frame 41 and a feed cylinder body 42 fixed on the second vibrating frame 41. The second vibrating frame 41 is driven to vibrate by another vibrating motor. The input end of the feed cylinder body 42 is connected to the feed port 32, and the bottom of the feed cylinder body 42 is provided with a first screen hole 421 for steel shot to pass through. A sorting box 8 is fixedly connected to the lower end of the feed cylinder body 42. A screen plate 81 is provided inside the sorting box 8. The screen plate 81 is densely covered with second screen holes 811 for blocking steel shot from passing through but allowing dust to pass through. The screen plate 81 divides the sorting box 8 into a steel shot sorting chamber 82 and a dust sorting chamber 83 from top to bottom. The steel shot sorting chamber 82 is connected to the feed cylinder body 42 through the first screen hole 421. A steel shot discharge port 821 is opened on one side of the bottom of the steel shot sorting chamber 82. The steel shot discharge port 821 is connected to the feed port 61 of the elevator 6 through a continuously inclined downward discharge channel 822.

[0037] After shot blasting, the feed cylinder body 42 vibrates under the drive of the second vibrating frame 41. This achieves directional conveying of the workpiece and, on the other hand, its vibrational energy continuously acts on the mixture of steel shot and dust within the feed cylinder body 42, effectively breaking up dust clumps that have agglomerated due to moisture or other reasons, making them loose and fine, thus creating favorable conditions for efficient screening in the sorting box 8. During conveying through the feed cylinder body 42, the steel shot and dust carried by the workpiece are first coarsely separated through the first screen hole 421. After falling into the sorting box 8, the steel shot and fine dust are then finely separated through the second screen hole 811 of the screen plate 81, achieving automatic and efficient separation of steel shot, dust, and processed workpieces. The separated pure steel shot is automatically returned to the elevator 6 for recycling through the unloading channel 822, greatly reducing steel shot loss and lowering production costs.

[0038] Reference Figure 2 and Figure 3 The feeding cylinder body 22 has a first suction pipe 221 connected to its cylinder wall, and a multi-port connector 731 is provided on the main air inlet pipe 73. The end of the first suction pipe 221 away from the feeding cylinder body 22 is connected to the multi-port connector 731. In this way, the dust-laden airflow generated during the operation of the vibrating feeding cylinder 2 can be connected to the main dust removal pipeline through the first suction pipe 221. This allows the dust raised during the feeding and conveying of workpieces to be captured and collected in advance before entering the shot blasting chamber 3, achieving source control of dust and avoiding dust pollution at the feeding end of the production line.

[0039] Reference Figure 1 , Figure 2 and Figure 8 A second suction pipe 422 is connected to the wall of the feeding cylinder body 42, and the end of the second suction pipe 422 away from the feeding cylinder body 42 is connected to the multi-port connector 731. In this way, the second suction pipe 422 at the vibrating feeding cylinder 4 is connected to the main dust removal system to perform secondary suction of the dust that is raised again during the feeding process, so as to ensure the cleanliness of the feeding end of the production line.

[0040] Reference Figure 2 and Figure 6 A third suction pipe 621 is connected to the upper end of one side wall of the discharge port 62 of the elevator 6. The side of the third suction pipe 621 away from the elevator 6 is connected to a multi-port connector 731. Since steel shot carries and agitates the airflow during lifting and transfer, causing dust to diffuse, a suction point is set near the discharge port 62 of the elevator 6 to extract the dust brought in by the elevator 6 during the steel shot lifting process. This prevents dust from spreading out of the elevator 6, protects the cleanliness of the steel shot supply and circulation system, and helps maintain the stable operation of the elevator 6 and the subsequent shot distribution system.

[0041] Reference Figure 2 , Figure 7 and Figure 8 A suction port 831 is provided on one side of the dust sorting chamber 83, and a fourth suction pipe 832 is connected to the suction port 831. The end of the fourth suction pipe 832 away from the dust sorting chamber 83 is connected to a multi-port connector 731. By venting the dust sorting chamber 83, fine dust particles can be accelerated to pass through the second screen hole 811 of the screen plate 81 and enter the dust sorting chamber 83 downwards, and be quickly drawn away, thereby promoting the separation efficiency of steel shot and dust, and preventing fine dust from re-adhering to the steel shot or being carried away by the airflow. In this way, the sorting effect is optimized, the cleanliness of the circulating steel shot is ensured, and the surface quality of the shot blasting casting is improved.

[0042] Reference Figure 7 The sorting box 8 has an opening 84 at one end, and a lifting sealing plate 85 is installed at the opening 84. The lifting sealing plate 85 is slidably connected to the sorting box 8 in the vertical direction. Guide grooves 86 are fixed on the inner walls of both sides of the sorting box 8, and the two sides of the screen plate 81 are slidably disposed in the corresponding guide grooves 86. A lifting drive component 411 is installed on the second vibration frame 41. The lifting drive component 411 is connected to the lifting sealing plate 85 to drive the lifting sealing plate 85 to rise and fall, thereby opening or closing the opening 84. In this embodiment, the lifting drive component 411 is one or a combination of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. In this way, the lifting sealing plate 85 can be easily opened and the screen plate 81 can be taken out for cleaning, effectively solving the problem of decreased sorting efficiency caused by dust or foreign objects adhering to the screen holes after long-term use, and ensuring the long-term stability of the sorting effect. Meanwhile, the detachable design of the sieve plate 81 allows for flexible replacement of the sieve plate 81 with different aperture sizes of the second sieve hole 811 according to the particle size of the steel shot used, so that the sorting accuracy always maintains the best match with the shot blasting medium, greatly expanding the adaptability of the production line to handle workpieces with different process requirements.

[0043] Reference Figure 1 , Figure 7 and Figure 8The output end of the induced draft fan 74 is equipped with an exhaust pipe 741, which is sealed by a cover plate 742. A first blowing pipe 743 is connected to the side wall of the exhaust pipe 741. A blowing port 823 is opened on one side of the steel shot sorting chamber 82, and the end of the first blowing pipe 743 away from the exhaust pipe 741 is connected to the blowing port 823. In this way, the clean, pressurized airflow after dust removal is drawn back to the steel shot sorting chamber 82 and blown from the side onto the falling steel shot and dust mixture, breaking the free settling state of the mixture and creating active and enhanced sorting conditions. First, the airflow can effectively remove the fine dust adhering to the surface of the steel shot, solving the adhesion problem caused by static electricity or oil. Secondly, the airflow forms a controllable turbulence within the steel shot sorting chamber 82, enhancing the separation effect between steel shot and dust and further purifying the recovered steel shot. This turbulence has a two-way effect: on the one hand, it gives some extremely fine, lightweight dust upward kinetic energy, enabling it to "return" and pass through the first screen hole 421 back into the feed cylinder body 42 space, where it is ultimately captured by the second suction pipe 422; on the other hand, it accelerates the process of the remaining majority of dust passing downward through the second screen hole 811 into the dust sorting chamber 83, preventing blockage or agitation during its descent, thus greatly improving screening efficiency and thoroughness. Simultaneously, this continuous airflow also provides forced cooling for the castings that have just undergone shot blasting and are at high temperatures, as well as for the steel shot being sorted, accelerating the cooling process and shortening the production cycle. This design achieves internal reuse of the purified airflow, improving sorting effect, cooling efficiency, and production efficiency in multiple ways.

[0044] Reference Figure 1 , Figure 8 and Figure 9 A second air blowing pipe 744 is connected to the side wall of the exhaust pipe 741. The end of the second air blowing pipe 744 away from the exhaust pipe 741 is connected to an air blowing hood 9. The air blowing hood 9 is located on one side of the unloading conveyor belt 5, and has multiple rectifier holes 91 on the side closest to the unloading conveyor belt 5. In this embodiment, the air blowing hood 9 is fixed above the unloading conveyor belt 5 by a fixing bracket 92. Thus, the airflow purified by the dust filter 7 is guided to the unloading conveyor belt 5 through the second air blowing pipe 744, realizing the utilization of waste energy from the high-pressure airflow. This allows for a final cleaning of the workpiece surface after shot blasting, removing any trace amounts of residual dust or steel shot debris that may be attached to the surface, resulting in a cleaner workpiece upon discharge. Furthermore, the airflow blown from the rectifier holes 91 serves as a final cooling process, uniformly and continuously cooling the high-temperature casting during the conveying process, ensuring that the temperature drops to a level safe for contact or direct processing by the end of the conveying process. This helps save on subsequent independent cooling or purging processes, achieving the effect of "cleaning and cooling immediately after production," optimizing the production process, saving time and space costs, and improving the intelligence and integration level of the production line.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
