Description

Technical Field

[0001] This utility model relates to the technical field of tracked shot blasting machines, specifically to a tracked shot blasting machine with a cleaning structure. Background Technology

[0002] Tracked shot blasting machines are used for surface treatment of metal products. They can remove oxide scale or rust from metal surfaces. During forging, heat treatment, and other processing, an oxide scale forms on the surface of metal products. Tracked shot blasting machines effectively remove this oxide scale by propelling shot at high speed. Furthermore, for metal products that are exposed to air or in humid environments for extended periods, which are prone to rust, tracked shot blasting machines can quickly remove rust from metal surfaces, prevent further rust spread, and extend the service life of metal products.

[0003] CN220218039U discloses a tracked shot blasting machine with a cleaning structure, including a machine body. An annular track is installed inside the machine body, and a filter screen is installed at an angle below the track. An elevator is located on one side of the machine body, and a drive motor is located on the top of the machine body. The drive motor drives the shot blaster to rotate and blast steel shot. A separator is located at the upper end of the machine body, and the separator transports intact steel shot into the shot blaster through a connecting pipe. A cleaning device is located on one side of the machine body, and a feeding device is located on the side of the annular track inside the machine body. The feeding device includes a feeding bin, and a connecting shaft is located at the upper end of the feeding bin. Support frames are connected to both ends of the connecting shaft. This tracked shot blasting machine uses a filter screen and a cleaning device to collect broken steel shot and dirt. The feeding device and vibrating screen achieve automatic loading and unloading, and also remove burrs and dust from the cleaned parts.

[0004] While existing technology CN220218039U has many advantages in use, it still has the following problems: its cleaning of workpieces is not perfect. Because the shot and workpiece are mixed during the process of shot treatment, the filtration speed of the shot through the annular track is low, and the shot will come into contact with the drive roller, which will affect the smoothness of the drive roller's driving of the annular track. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a tracked shot blasting machine with a cleaning structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is a tracked shot blasting machine with a cleaning structure, including a shell, a drive plate and a feed port. The drive plate is provided at the upper end of the shell. The drive plate has a through hole. Bearing seats are screwed to both sides of the lower outer wall of the drive plate. An adjusting roller is rotatably installed inside the bearing seat. An annular track is sleeved on the outside of the adjusting roller. Tension roller and drive roller are respectively provided on both sides of the inner wall of the annular track. A blocking plate is screwed to both sides of the lower outer wall of the drive plate. A feed port is provided on one side of the outer wall of the shell. A baffle plate is rotatably installed at the lower end of the inner wall of the feed port.

[0007] By adopting the above technical solution, the adjusting roller, in conjunction with the drive roller and tension roller, can achieve stable rotation of the annular track. The drive roller, in conjunction with an external drive motor, can drive the annular track to rotate. Furthermore, the tension roller, in conjunction with an externally used adjusting structure, can adjust its height, thereby adjusting the tension of the annular track. This ensures stable operation of the annular track due to the friction between the track and the adjusting roller, drive roller, and tension roller. The drive plate can be driven vertically by an electric push rod, thereby adjusting the positions of the adjusting roller and the blocking plate. When the adjusting roller, blocking plate, and support wheel move upwards, they can adjust the annular track... The recessed position of the ring track is adjusted to be inclined, which facilitates the rolling of workpieces that were originally gathered in the recessed area of ​​the ring track through the inclined surface. This achieves the purpose of centralized cleaning and removal of workpieces on the outside of the ring track. When the ring track deforms, it contacts one side of the lower outer wall of the baffle plate and pushes the baffle plate to rotate against the magnetic attraction. This causes the baffle plate to rotate upward in a circle, so that the workpieces on the outside of the ring track can be rolled out through the baffle plate. The workpieces fall into the collection box through the feed port for collection, which can improve the centralized collection efficiency of workpieces and improve the processing efficiency of the device.

[0008] Specifically, inspection covers are screwed to both sides of the outer wall of the outer shell, and the inspection covers are positioned corresponding to the adjusting rollers. A shot blasting device is screwed to one side of the upper outer wall of the outer shell, and the shot blasting device is connected to the inside of the outer shell. An outlet is provided on one side of the lower end of the inner wall of the outer shell.

[0009] By adopting the above technical solution, the inspection cover can maintain the relative sealing of the inside of the shell and facilitate the inspection and maintenance of components such as the adjusting roller. It does not require disassembling a large number of parts, saving maintenance time and costs. After being thrown by the shot blaster, the shot will penetrate the through hole and finally be projected onto the surface of the workpiece on the ring track, thereby processing the workpieces accumulated in the recess of the ring track. As the drive roller drives the ring track to rotate, it can move the workpiece. Due to the mutual friction between the workpieces, the processing surface of the workpiece can be changed, ensuring the comprehensive processing of the workpiece. The cleaned waste and shot can be discharged through the discharge port, and the discharged shot is lifted and transferred by the matching elevator for shot recycling.

[0010] Specifically, a support arm is screwed to one side of the outer wall of the baffle plate, and a support wheel for guidance is rotatably installed on one side of the outer wall of the support arm, and the support wheel is in contact with the outer wall of the annular track.

[0011] By adopting the above technical solution, the support wheel ensures stability in the external position of the blocking plate through the support arm. The support wheel can provide additional support and guidance for the ring track, ensure the stability of the range of the ring track's recess, and, together with the blocking plate, restrict the position of the workpiece.

[0012] Specifically, a door panel is rotatably connected to one side of the outer wall of the housing. The size of the door panel is larger than the size of the material feeding port, and the door panel is positioned corresponding to the material feeding port.

[0013] By adopting the above technical solution, workers can put the workpiece to be processed into the recess of the annular track through the feed port, and the door panel can block the feed port, playing a sealing and protective role, preventing shot and dust from flying out of the feed port.

[0014] Specifically, a platform is installed on the lower end of one side of the outer wall of the shell, and a storage groove is opened on the upper outer wall of the platform. A collection box for collecting materials is placed inside the storage groove.

[0015] By adopting the above technical solution, the collection box is located inside the storage trough, which can ensure a stable placement position. The collection box can easily collect the materials discharged from the material outlet, making it convenient for centralized processing.

[0016] Specifically, both sides of the upper outer wall of the housing are screwed together with electric push rods that provide power, and the lower end of the electric push rods is screwed together with the outer wall of the drive plate.

[0017] By adopting the above technical solution, the height of the drive plate and the adjusting roller can be adjusted by electric push rod, thereby adjusting the distribution position of the ring track and making the ring track adapt to the processing and cleaning requirements of the workpiece.

[0018] Specifically, a magnet is bonded and fixed to the lower end of the inner wall of the feed port. The magnet is attracted to the outer wall of the baffle plate. The baffle plate is arranged at an angle, and one side of the baffle plate is located at the upper end of the annular track.

[0019] By adopting the above technical solution, the adsorption effect between the magnet and the baffle plate can restrict the position of the baffle plate. Therefore, the distance between the baffle plate and the ring track can restrict the movement of the workpiece, allowing the projectiles on the outside of the ring track to pass through while restricting the workpiece and preventing it from leaving the outside of the ring track. When the baffle plate is in normal use, it is at a downward tilt angle. When the baffle plate moves with the ring track, it is at an upward tilt angle, so that the workpiece on the outside of the ring track rolls out through the baffle plate. The magnet is made of ferrite magnetic material, which has low magnetism. Therefore, while it can attract the baffle plate, it can prevent the workpiece from being attracted to the outside of the baffle plate.

[0020] Specifically, slide rails for limiting movement trajectory are installed on both sides of the inner wall of the outer shell, and a slider is installed on one side of the outer wall of the blocking plate, and the slider is slidably installed inside the slide rail.

[0021] By adopting the above technical solution, the slider and slide rail achieve precise position adjustment and movement of the blocking plate, and ensure that the gap between the blocking plate and the annular track is uniform, effectively blocking the workpiece.

[0022] The beneficial effects of this utility model are:

[0023] (1) The tracked shot blasting machine with a cleaning structure described in this utility model can adjust the concave position of the annular track, so that the concave position of the annular track is adjusted to an inclined shape, which makes it easier for the workpieces that were originally gathered in the concave position of the annular track to roll through the inclined surface, thereby achieving the purpose of cleaning and removing the workpieces on the outer side of the annular track.

[0024] (2) The tracked shot blasting machine with a cleaning structure described in this utility model has an annular track in contact with one side of the lower outer wall of the baffle plate, and pushes the baffle plate to rotate against the magnetic attraction, so that the baffle plate rotates upward in a circle, thereby the workpiece on the outside of the annular track can be rolled out through the baffle plate, and the workpiece falls into the collection box through the feed port for collection, which can improve the efficiency of centralized collection of workpieces and improve the processing efficiency of the device for workpieces.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention discloses a tracked shot blasting machine with a cleaning structure, comprising a shell 1, a drive plate 2, and a feed port 3. The drive plate 2 is provided at the upper end of the shell 1, and a through hole 21 is provided inside the drive plate 2. Bearing seats 22 are screwed to both sides of the lower outer wall of the drive plate 2. An adjusting roller 23 is rotatably installed inside the bearing seat 22. An annular track 24 is sleeved on the outside of the adjusting roller 23. Tensioning rollers 26 and drive rollers 25 are respectively provided on both sides of the inner wall of the annular track 24. Baffle plates 27 are screwed to both sides of the lower outer wall of the drive plate 2. A feed port 3 is provided on one side of the outer wall of the shell 1, and a baffle plate 31 is rotatably installed at the lower end of the inner wall of the feed port 3.

[0033] In use, the adjusting roller 23, in conjunction with the drive roller 25 and the tension roller 26, enables the stable rotation of the annular track 24. The drive roller 25, in conjunction with an external drive motor, drives the annular track 24 to rotate. The tension roller 26, in conjunction with an externally used adjusting structure, allows for adjustment of its height, thereby adjusting the tension of the annular track 24. This ensures stable operation of the annular track 24 by maintaining sufficient friction between the track 24 and the adjusting roller 23, drive roller 25, and tension roller 26. Furthermore, the drive plate 2 can be driven vertically by the electric push rod 12, thereby adjusting the position of the adjusting roller 23 and the blocking plate 27. When the adjusting roller 23, blocking plate 27, and support wheel 29 move upwards, they can adjust the tension of the track. The concave position of the annular track 24 is adjusted to make it inclined, which facilitates the rolling of workpieces that were originally gathered in the concave position of the annular track 24 through the inclined surface. This achieves the purpose of centralized cleaning and removal of workpieces on the outside of the annular track 24. When the annular track 24 deforms, it contacts one side of the lower outer wall of the baffle plate 31 and pushes the baffle plate 31 to rotate against the attraction of the magnet 32. This causes the baffle plate 31 to rotate upward in a circle, so that the workpieces on the outside of the annular track 24 can be rolled out through the baffle plate 31. The workpieces fall into the collection box 16 through the feed port 3 for collection, which can improve the centralized collection efficiency of workpieces and improve the processing efficiency of the device.

[0034] For shot blasting, for example, such as Figure 2 As shown, both sides of the outer wall of the outer shell 1 are screwed with inspection cover plates 11, which correspond to the position of the adjusting roller 23. A shot blasting machine 13 is screwed to one side of the upper outer wall of the outer shell 1. The shot blasting machine 13 is connected to the inside of the outer shell 1. An outlet 17 is opened on one side of the lower end of the inner wall of the outer shell 1.

[0035] During use, the inspection cover 11 can maintain the relative sealing of the inside of the outer shell 1 and facilitate the inspection and maintenance of components such as the adjusting roller 23 by the staff. It does not require disassembling a large number of parts, saving maintenance time and costs. After the shot is thrown out by the shot blaster 13, the shot will penetrate the through hole 21 and finally be thrown onto the surface of the workpiece on the annular track 24, thereby realizing the processing of the workpieces gathered in the recess of the annular track 24. As the drive roller 25 drives the annular track 24 to rotate, it can drive the workpiece to move. Due to the mutual friction between the workpieces, the processing surface of the workpiece can be changed to ensure the comprehensive processing of the workpiece. The cleaned waste and shot can be discharged through the discharge port 17, and the discharged shot is lifted and transferred by the matching elevator for shot recycling.

[0036] For guidance, exemplified, such as Figure 4As shown, a support arm 28 is screwed to one side of the outer wall of the baffle plate 27, and a support wheel 29 for guidance is rotatably installed on one side of the outer wall of the support arm 28. The support wheel 29 is in contact with the outer wall of the annular track 24.

[0037] During use, the support wheel 29 ensures stability in the external position of the blocking plate 27 through the support arm 28. The support wheel 29 can provide additional support and guidance for the ring track 24, ensuring the stability of the recessed area of ​​the ring track 24, and can restrict the position of the workpiece in conjunction with the blocking plate 27.

[0038] For example, for feeding and discharging materials, such as Figure 2 As shown, a door panel 14 is rotatably connected to one side of the outer wall of the outer casing 1. The size of the door panel 14 is larger than the size of the material outlet 3, and the door panel 14 and the material outlet 3 are positioned opposite each other.

[0039] During use, workers can feed the workpiece to be processed into the recess of the annular track 24 through the feed port 3, and the door plate 14 can block the feed port 3, which plays a sealing and protective role, preventing shot and dust from flying out of the feed port 3.

[0040] To collect the workpieces, for example, such as Figure 1 As shown, a platform 15 is installed on the lower end of the outer wall of one side of the outer casing 1. A storage groove is opened on the upper outer wall of the platform 15, and a collection box 16 for collecting materials is placed inside the storage groove.

[0041] When in use, the collection box 16 is placed inside the storage slot to ensure a stable position. The collection box 16 can easily collect the material discharged from the material outlet 3 for centralized processing.

[0042] To drive movement, for example, such as Figure 2 As shown, electric push rods 12 that provide power are screwed to both sides of the upper outer wall of the outer casing 1, and the lower end of the electric push rods 12 is screwed to the outer wall of the drive plate 2.

[0043] During use, the height of the drive plate 2 and the adjusting roller 23 can be adjusted by the electric push rod 12, thereby adjusting the distribution position of the annular track 24 and making the annular track 24 adapt to the processing and cleaning requirements of the workpiece.

[0044] For the purpose of blocking material, for example, such as Figure 3 As shown, a magnet 32 ​​is bonded and fixed to the lower end of the inner wall of the feed port 3. The magnet 32 ​​is attracted to the outer wall of the baffle plate 31. The baffle plate 31 is arranged at an angle, and one side of the baffle plate 31 is located at the upper end of the annular track 24.

[0045] During use, the attraction between magnet 32 ​​and baffle plate 31 restricts the position of baffle plate 31. Therefore, the distance between baffle plate 31 and annular track 24 restricts the movement of workpiece, allowing projectiles on the outside of annular track 24 to pass through while restricting the workpiece and preventing it from detaching from the outside of annular track 24. During normal use, baffle plate 31 is tilted downwards. When baffle plate 31 moves with annular track 24, it tilts upwards, allowing workpieces on the outside of annular track 24 to roll out through baffle plate 31. Magnet 32 ​​is made of ferrite magnetic material with low magnetism, thus attracting baffle plate 31 while preventing workpieces from being attracted to the outside of baffle plate 31.

[0046] To limit the movement trajectory, for example, such as Figure 2 As shown, slide rails 18 for limiting the movement trajectory are installed on both sides of the inner wall of the outer casing 1, and a slider is installed on one side of the outer wall of the blocking plate 27, and the slider is slidably installed inside the slide rail 18.

[0047] During use, the slider and slide rail 18 enable precise position adjustment and movement of the blocking plate 27, and ensure uniform gap between the blocking plate 27 and the annular track 24, effectively blocking the workpiece.

[0048] In use, the operator opens the door panel 14 and places the workpiece to be processed into the recess of the annular track 24 through the feed port 3. The drive motor is then turned on, causing the drive roller 25 to rotate, which in turn drives the annular track 24 to rotate. Simultaneously, the tension roller 26 adjusts its height via an external adjustable structure to regulate the tension of the annular track 24, ensuring appropriate friction between the annular track 24 and the adjusting roller 23, drive roller 25, and tension roller 26. The shot blasting machine 13 is then started, ejecting shot that penetrates the through-hole 21 inside the drive plate 2 and strikes the surface of the workpiece on the annular track 24, cleaning and processing the workpiece.

[0049] As the annular track 24 rotates, the workpiece moves in the track recess. Due to the friction between the workpieces, the machining surface can be changed, and the workpiece can be fully machined. During this process, the support wheel 29 provides additional support and guidance to the annular track 24 through the support arm 28. Together with the baffle plate 27, it restricts the position of the workpiece and ensures that the workpiece is in a suitable machining area. The cleaned waste and shot fall into the housing 1 through the baffle plate 31 and are then discharged through the discharge port 17.

[0050] The electric push rod 12 is controlled by an external controller. The electric push rod 12 drives the drive plate 2 to move vertically, thereby adjusting the position of the adjusting roller 23 and the blocking plate 27. When the adjusting roller 23, the blocking plate 27 and the support wheel 29 move upward, the concave position of the annular track 24 is adjusted to an inclined shape due to the displacement, which facilitates the workpieces that were originally gathered in the concave position to roll through the inclined surface.

[0051] When the annular track 24 deforms, it comes into contact with one side of the lower outer wall of the baffle plate 31 and pushes the baffle plate 31 to overcome the attraction of the magnet 32 ​​and rotate upward in a circular motion. At this time, the workpiece on the outside of the annular track 24 can roll through the baffle plate 31 and fall into the collection box 16 through the feed port 3 for collection.

All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
