Description

Technical Field

[0001] This invention relates to the field of shot blasting machine technology, specifically to a shot blasting machine and shot blasting treatment method for steel product processing. Background Technology

[0002] Shot blasting machines for steel product processing are used to remove rust from the surface of steel products. They clean and strengthen the surface of steel products by impacting it with high-speed metal shot. Track-type shot blasting machines have multiple shot blasting ports on both the upper and lower sides of the cleaning chamber to perform shot blasting on the steel products over a wide area for comprehensive cleaning.

[0003] Multiple conveyor rollers are installed in the cleaning chamber. Steel products move along these rollers as they enter. The shot blasting nozzles, located below the chamber, are positioned between adjacent conveyor rollers. During shot blasting, the metal projectiles ejected from the nozzles are scattered. Only the steel products directly above the nozzles receive a relatively strong impact from the projectiles; the remaining areas only experience impacts from the scattered projectiles. Because the steel products need to be in close contact with and supported by the conveyor rollers during transport, although each location passes through the blasting nozzle, most of the scattered projectiles collide with the conveyor rollers, resulting in surface damage to the steel products. The impact time of the shot blasting is relatively short, and there are often gaps on a single conveyor roller. These gaps are the joints between multiple sections of the conveyor roller. When a steel product passes over a conveyor roller, the position corresponding to the gap will not come into contact with the conveyor roller, but it will still be impacted by the metal shot. The shot blasting time is significantly longer than in other positions. This results in multiple longitudinal cleaning marks being formed on the steel product at the position corresponding to the gap after shot blasting. Current technologies often use methods such as setting different conveyor rollers with staggered gaps or reducing the gap size to mitigate the impact of the gaps. However, the gaps still exist, and the cleaning effect on the underside of the steel product is still insufficient. Summary of the Invention

[0004] The purpose of this invention is to provide a shot blasting machine and shot blasting method for steel product processing, so as to solve the technical problem in the prior art that the side in contact with the conveyor roller is unevenly or insufficiently treated when steel products are shot blasted during the conveying process.

[0005] In one possible implementation, a shot blasting machine for steel product processing includes a cleaning chamber, a shot blasting circulation device, and multiple shot blasters. The shot blasting circulation device is installed on the cleaning chamber, and the multiple shot blasters are installed inside the cleaning chamber, respectively located on the upper and lower sides of the cleaning chamber. Steel products are conveyed into the cleaning chamber, and the shot blasting circulation device delivers shot to the shot blasters to perform shot blasting treatment on the steel products. The machine also includes a first conveyor roller, a second conveyor roller, a first lifting mechanism, and a second lifting mechanism. The first and second conveyor rollers are arranged alternately in the cleaning chamber, with a cleaning gap between adjacent first and second conveyor rollers. The shot blasters located on the lower side of the cleaning chamber are positioned within the cleaning gap. Correspondingly, two lifting mechanisms are respectively installed on the inner walls of both sides of the cleaning chamber. The first conveyor roller and the second conveyor roller are rotatably connected to the two lifting mechanisms. The first lifting mechanism can drive the first conveyor roller or the second conveyor roller to move longitudinally. The two lifting mechanisms are respectively installed on both sides of the bottom of the cleaning chamber. The first conveyor roller and the second conveyor roller are rotatably connected to the two lifting mechanisms. The second lifting mechanism can drive the first conveyor roller or the second conveyor roller to move longitudinally. The first conveyor roller and the second conveyor roller can be rotated to an inclined state. When the steel product enters the cleaning chamber, the two sides of the steel product slide on the first conveyor roller and the second conveyor roller respectively.

[0006] The two ends of the first conveyor roller are respectively connected to the first and second lifting mechanisms that are far apart from each other. The two ends of the second conveyor roller are also respectively connected to the first and second lifting mechanisms that are far apart from each other. For example, the first conveyor roller is connected to the first lifting mechanism on the left side of the cleaning chamber and to the second lifting mechanism on the right side. The second conveyor roller is connected to the first lifting mechanism on the right side of the cleaning chamber and to the second lifting mechanism on the left side.

[0007] The lifting mechanism includes a longitudinal track, a sliding seat, and a drive cylinder. Multiple longitudinal tracks are fixedly connected in the cleaning chamber. The sliding seat is slidably connected to the longitudinal track. The sliding seat is rotatably connected to the conveyor roller or the conveyor roller. Multiple drive cylinders are fixedly installed on the top of the cleaning chamber. The output end of the drive cylinder is fixedly connected to the sliding seat.

[0008] The second lifting mechanism includes a second drive cylinder, a lifting frame, a transverse track, and a second sliding seat. Multiple second drive cylinders are installed at the bottom of the cleaning chamber. The lifting frame is fixedly connected to the output ends of multiple second drive cylinders. Multiple transverse tracks are provided on the lifting frame. A second sliding seat is slidably connected in the transverse tracks. The second sliding seat is rotatably connected to the first conveyor roller or the second conveyor roller.

[0009] When the output end of the drive cylinder shortens, it can pull the sliding seat to slide upward. The sliding seat drives the conveyor roller 1 or the conveyor roller 2 to rotate to an inclined state. The conveyor roller 1 or the conveyor roller 2 drives the sliding seat 2 to slide on the transverse track.

[0010] Rangefinders are installed on both inner walls of the cleaning chamber. The contact position between the steel product and either conveyor roller one or conveyor roller two is at the same height as the rangefinder in the cleaning chamber. Conveyor roller one and conveyor roller two are respectively aligned with the two rangefinders. Based on the width of the steel product, the rangefinder measures the support height on both sides when the steel product enters the cleaning chamber, so as to avoid the steel product colliding with conveyor roller one or conveyor roller two.

[0011] Multiple conveying devices are installed at the bottom center of the cleaning chamber. These conveying devices can move the steel products that enter the cleaning chamber. Conveying devices are installed at both ends of the cleaning chamber, and the steel products are moved by the conveying devices.

[0012] The first sliding seat is provided with a sealing cover, which shields the output end of the first drive cylinder and the longitudinal track. The first sliding seat is provided with a chip discharge port at a position in the longitudinal track, through which metal pellets entering the longitudinal track can flow downward in the longitudinal track. The second sliding seat is connected with a cover plate, which covers the transverse track.

[0013] A shot blasting treatment method for processing steel products, based on the aforementioned shot blasting machine for processing steel products, includes the following steps: Step 1, tilting rotation: The output ends of multiple drive cylinders 1 shorten, pulling slide seat 1 to slide upward on the longitudinal track. At this time, both conveyor roller 1 and conveyor roller 2 rotate in an inclined state, and both conveyor roller 1 and conveyor roller 2 pull slide seat 2 to slide on the transverse track. Step 2, Height Measurement: The distance measuring instrument measures the contact height of the steel product and the distance between conveyor roller one and conveyor roller two; Step 3: Adjust the height: The output end of the drive cylinder 2 shortens and pulls the lifting frame downward. Adjust the distance between conveyor roller 1 and conveyor roller 2 at the contact height of the steel product. Step 4, Steel Product Operation: The steel product enters the clean room, and the conveying device drives the steel product to move at a constant speed. Conveying roller one and conveying roller two contact the two sides of the steel product respectively. Step 5, shot blasting: When the steel product passes through the shot blaster, the shot blaster performs shot blasting treatment on the surface of the steel product.

[0014] The significant technical effects of the embodiments of the present invention are as follows: 1. This invention sets up two conveyor rollers, one and two, which are staggered and can be rotated to an inclined state. When in the inclined state, the steel product is supported only on both sides in the cleaning chamber, and contacts the two conveyor rollers respectively. Compared with the traditional through-type shot blasting machine, the bottom of the steel product is not directly supported. The metal shot sprayed by the shot blasting machine is not blocked by the conveyor rollers. The metal shot can freely diffuse and spray towards the steel product. There is no influence from the roller gap position. All positions will receive the same support effect, thus improving the shot blasting effect. 2. By setting up lifting mechanism one and lifting mechanism two, the present invention can drive conveyor roller one and conveyor roller two to rotate, and at the same time adjust their overall height in the cleaning chamber. It can also control the conveyor roller one and conveyor roller two to be parallel at the same angle, which is the same as the effect of the traditional through shot blasting machine.

[0025] Example 1 This invention illustrates a shot blasting machine for steel product processing according to one embodiment of the present invention. It includes a cleaning chamber 1, a shot blasting circulation device 2, and multiple shot blasters 3. The shot blasting circulation device 2 is installed on the cleaning chamber 1, and the multiple shot blasters 3 are installed inside the cleaning chamber 1, respectively located on the upper and lower sides of the cleaning chamber 1. Steel products are conveyed into the cleaning chamber 1, and the shot blasting circulation device 2 delivers shot to the shot blasters 3 to perform shot blasting treatment on the steel products. Please refer to [link to relevant documentation]. Figures 1-6 It also includes conveyor roller 101, conveyor roller 202, lifting mechanism 1, and lifting mechanism 2. Multiple conveyor rollers 101 and 202 are arranged alternately in the cleaning chamber 1, with cleaning gaps between adjacent conveyor rollers 101 and 202. The shot blaster 3, located on the lower side of the cleaning chamber 1, corresponds to these cleaning gaps. Two lifting mechanisms 1 are respectively installed on the inner walls of both sides of the cleaning chamber 1. Conveyor rollers 101 and 202 are rotatably connected to the two lifting mechanisms 1. The lifting mechanisms 1 can drive either conveyor roller 101 or conveyor roller 202 to move longitudinally. Two lifting mechanisms are respectively set on both sides of the bottom of the cleaning chamber 1. Conveyor roller 101 and conveyor roller 2 102 are rotatably connected to the two lifting mechanisms. The lifting mechanism can drive conveyor roller 101 or conveyor roller 2 102 to move longitudinally. Conveyor roller 101 and conveyor roller 2 102 can be rotated to an inclined state. The two lifting mechanisms drive conveyor roller 101 and conveyor roller 2 102 to tilt in the same opposite angle. When the steel product enters the cleaning chamber 1, it will move in the center of the cleaning chamber 1. The two sides of the steel product slide on conveyor roller 101 and conveyor roller 2 102 respectively.

[0026] Both ends of conveyor roller 101 are connected to lifting mechanism 1 and lifting mechanism 2, which are located far apart from each other. Both ends of conveyor roller 102 are also connected to lifting mechanism 1 and lifting mechanism 2, which are located far apart from each other. Please refer to [link / reference needed]. Figures 1-2 For example, conveyor roller 101 is connected to the lifting mechanism 1 on the left side of the cleaning chamber 1 and to the lifting mechanism 2 on the right side. Conveyor roller 2 102 is connected to the lifting mechanism 1 on the right side of the cleaning chamber 1 and to the lifting mechanism 2 on the left side. Conveyor roller 101 and conveyor roller 2 102 are arranged alternately.

[0027] The lifting mechanism includes longitudinal rails 201, sliding seats 202, and drive cylinders 203. Multiple longitudinal rails 201 are fixedly connected in the cleaning chamber 1. (See attached image.) Figures 2-4 A sliding seat 202 is slidably connected to the longitudinal track 201. The sliding seat 202 is rotatably connected to the conveyor roller 101 or the conveyor roller 202. Multiple drive cylinders 203 are fixedly installed on the top of the cleaning chamber 1. The output end of the drive cylinder 203 is fixedly connected to the sliding seat 202. When the output end of the drive cylinder 203 shortens, it pulls the sliding seat 202 to slide on the longitudinal track 201, thereby causing one end of the conveyor roller 101 or the conveyor roller 202 to tilt upwards. Figure 6 As shown, a sealing cover 204 is provided on the sliding seat 202. The sealing cover 204 shields the output end of the drive cylinder 203 and the longitudinal track 201. A chip discharge port 205 is provided on the sliding seat 202 at the position in the longitudinal track 201. The sealing cover 204 protects the output end of the drive cylinder 203. When the metal shot enters the longitudinal track 201 through the gap of the sealing cover 204, it can flow down the longitudinal track 201 through the chip discharge port 205 and be discharged, so as to prevent the metal shot from affecting the sliding seat 202 on the longitudinal track 201.

[0028] The second lifting mechanism includes a second drive cylinder 301, a lifting frame 302, a transverse track 303, and a second sliding seat 304. Multiple second drive cylinders 301 are installed at the bottom of the cleaning chamber 1. The lifting frame 302 is fixedly connected to the output ends of the multiple second drive cylinders 301. Multiple transverse tracks 303 are provided on the lifting frame 302, and the second sliding seat 304 is slidably connected in the transverse tracks 303. The second sliding seat 304 is rotatably connected to either the first conveyor roller 101 or the second conveyor roller 102. When the first conveyor roller 101 or the second conveyor roller 102 rotates and tilts under the drive of the output end of the first drive cylinder 203, the first conveyor roller 101 and the second conveyor roller 102 can pull the second sliding seat 304 to slide on the transverse track 303. When the output end of the second drive cylinder 301 drives the lifting frame 302 to move vertically, it can cooperate with the first drive cylinder 203, so that the first conveyor roller 101 and the second conveyor roller 102 can maintain a certain angle at any height. Figure 2 and Figure 4As shown, the angles of conveyor roller 101 and conveyor roller 102 are different at this time, and can be adjusted according to the volume and width of the steel product. Figure 5 As shown, a cover plate 305 is connected to the sliding seat 2 304. The cover plate 305 covers the transverse track 303. When the sliding seat 2 slides on the transverse track 303, the cover plate 305 can prevent metal projectiles from entering the transverse track 303 and avoid clogging the transverse track 303.

[0029] Rangefinders 4 are installed on both inner walls of the cleaning chamber 1. The contact position between the steel product and conveyor roller 101 or conveyor roller 202 is at the same height as the rangefinder 4 in the cleaning chamber 1. The rangefinder 4 measures the width of the actual support position of the steel product by conveyor roller 101 and conveyor roller 202. Figure 2 and Figure 3 As shown, conveyor roller 101 and conveyor roller 202 are aligned with two rangefinders 4 respectively. Based on the width of the steel product, the rangefinders 4 measure the support height on both sides when the steel product enters the cleaning chamber 1. When the support position of conveyor roller 101 and conveyor roller 202 on the steel product is too high or too low, the steel product will collide with conveyor roller 101 or conveyor roller 202 when they come into contact.

[0030] like Figures 1-3 As shown, multiple conveying devices 103 are provided at the bottom center of the cleaning chamber 1. The conveying devices 103 can drive the steel products entering the cleaning chamber 1 to move. Conveying devices 103 are provided at both ends of the cleaning chamber 1. The steel products are driven by the conveying devices 103 to move. The conveying devices 103 at both ends are not affected by the shot blaster 3 and do not obstruct the shot blasting path.

[0031] Compared with the prior art, this embodiment provides a shot blasting machine and shot blasting method for steel product processing. The conveying device 103 is set at both ends of the cleaning chamber 1, and pushes the steel products when they enter and leave the cleaning chamber 1. This avoids the same impact as the traditional through-type shot blasting machine caused by the contact surface between the conveying device 103 and the steel products. The output end of the drive cylinder 1 203 shortens and pulls the conveying roller 101 and the conveying roller 2 102 to tilt. The output end of the drive cylinder 2 301 moves the lifting frame 302 to descend, thereby adjusting the conveying roller 101. 1. The overall height of conveyor roller 101 and conveyor roller 202 is measured by a distance measuring instrument 4. This prevents steel products from shifting downwards or upwards when entering the cleaning chamber 1, which could cause impacts on conveyor roller 101 and conveyor roller 202. When the shot blasting machine 3 on the lower side of the steel product performs shot blasting, the movement path of the metal shot will not be affected by conveyor roller 101 and conveyor roller 202, making the shot blasting effect relatively uniform at each position on the lower side.

[0032] Example 2 A shot blasting treatment method for processing steel products, based on the aforementioned shot blasting machine for processing steel products, includes the following steps: Step 1, tilting rotation: The output ends of multiple drive cylinders 203 shorten, pulling slide seat 202 to slide upward on longitudinal track 201. At this time, conveyor roller 101 and conveyor roller 202 both rotate to a tilted state. Simultaneously, conveyor roller 101 and conveyor roller 202 both pull slide seat 204 to slide on transverse track 303. Step 2, Height Measurement: The distance measuring instrument 4 measures the pre-contact height of the steel product and the distance between conveyor roller 101 and conveyor roller 202; Step 3, Adjust the height: The output end of the drive cylinder 2 301 shortens and pulls the lifting frame 302 downward, adjusting the distance between the conveyor roller 1 101 and the conveyor roller 2 102 at the contact height of the steel product; Step 4, Steel Product Operation: The steel product enters the cleaning chamber 1, and the conveying device 103 drives the steel product to move at a constant speed. Conveying roller 101 and conveying roller 2 102 respectively contact the two sides of the steel product. Step 5, shot blasting: When the steel product passes through the shot blaster 3, the shot blaster 3 performs shot blasting treatment on the surface of the steel product.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
