Description

Technical Field

[0001] This application relates to the field of shot blasting equipment technology, and in particular to a loading and unloading transfer device for shot blasting machines. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings, and are widely used in the foundry industry for removing sand and oxide scale from the surface of cast steel and cast iron parts.

[0003] One type of traditional roller conveyor shot blasting equipment works by placing the workpiece on the conveyor rollers and driving it into the cleaning chamber for shot blasting. It is highly efficient and safe, and is mainly used for surface treatment of metal materials such as steel plates, steel pipes, and structural steel. It can achieve continuous conveying to remove oxide scale, clean and pre-treat the surface of steel. For complex shaped parts, tooling assistance is required during operation, otherwise the problem of workpiece placement cannot be solved.

[0004] In shot blasting, refer to Figure 1 Roller-type shot blasting equipment is relatively long, so the corresponding workshop area is large. Generally, it can be equipped with three loading stations and two unloading stations (the number varies), which can simultaneously connect to steel produced by multiple upstream production lines and meet the copper loading needs of multiple downstream production lines.

[0005] After shot blasting, the tooling needs to be transferred back to the loading station to place the workpiece, achieving tooling circulation and reuse. Due to the large weight of both the tooling and the workpiece, manual lifting with overhead cranes is required for this transfer, resulting in high labor costs. Furthermore, with a large number of loading and unloading stations, the slow crane speed makes timely tooling transfer impossible, failing to meet the needs of multiple production lines and impacting production efficiency. Increasing the number of shot blasting machines and overhead cranes could solve the efficiency problem, but it would significantly increase equipment and space costs. Alternatively, reducing the number of production lines matched with each shot blasting machine could alleviate the tooling transfer problem, but it would waste workshop space, preventing manufacturers from expanding production scale and reducing production efficiency. Therefore, there is an urgent need to solve the tooling circulation problem in traditional shot blasting. Utility Model Content

[0006] To address the aforementioned problems, realize the circulation of tooling, improve production speed, expand production scale, increase production efficiency, and reduce production costs, this application provides a loading and unloading circulation device for shot blasting machines.

[0007] The technical solution of the loading and unloading transfer device for shot blasting machine provided in this application is as follows.

[0008] A loading and unloading transfer device for a shot blasting machine includes: The feeding roller conveyor, located at the feeding end of the shot blasting machine, is used to transport workpieces to the shot blasting machine; The feed roller conveyor, located at the feed end of the shot blasting machine, is used for conveying the workpieces output from the shot blasting machine. The tooling transfer roller conveyor and several conveying mechanisms are provided. One end of the tooling transfer roller conveyor is connected to the loading roller conveyor through the conveying mechanism, and the other end of the tooling transfer roller conveyor is connected to the unloading roller conveyor through the conveying mechanism. The conveying mechanism includes a conveying base frame, on which a sliding seat is provided. The sliding seat is moved by a first power unit, and a lifting platform is provided on the sliding seat. The lifting platform is lifted by a second power unit.

[0009] By adopting the above technical solution, the loading and unloading roller conveyors enable the conveying of workpieces, achieving both loading and unloading. Through the tooling transfer track, in conjunction with the conveying mechanism, tooling on the downstream roller conveyor can be lifted and transferred to the other end of the tooling transfer roller conveyor, or tooling on one end of the tooling transfer roller conveyor can be lifted and transferred to the loading roller conveyor. This achieves tooling circulation, eliminating the need for manual operation, reducing labor costs, and increasing tooling turnover speed. This allows the shot blasting machine to maintain maximum efficiency, meeting the production needs of upstream and downstream production lines, increasing production speed, and improving production efficiency.

[0010] Optionally, the tooling conveyor rollers are parallel to the loading rollers and the unloading rollers.

[0011] By adopting the above technical solution, the loading roller conveyor is parallel to the unloading roller conveyor, ensuring that the tooling between different roller conveyors is transferred through the conveying mechanism.

[0012] Optionally, a conveying base frame is provided laterally between the tooling transfer roller conveyor and the feeding roller conveyor, and between the tooling transfer roller conveyor and the unloading roller conveyor.

[0013] Optionally, the transport base frame includes two sets of transport rails spaced apart, and each set of transport rails is supported by a sliding seat via rail wheels.

[0014] By adopting the above technical solution, the sliding seat can be supported on the transport rail frame by the rail wheels, thus realizing the movement of the sliding seat along the transport rail frame. By setting two sets of transport rail frames, two sliding seats can slide, and two lifting platforms can support the movement of the tooling at the same time, which is beneficial to improving the stability of the tooling transfer.

[0015] Optionally, the first power unit includes a drive motor disposed at the end of the transport rail frame. The drive motor is used to drive the drive wheel to rotate. The two ends of the transport rail frame are respectively provided with a drive wheel and a driven wheel. The two sets of drive wheels at the ends of the transport rail frame are coaxially connected by a transmission shaft. The drive wheel and the driven wheel are connected by a transmission belt. The sliding seat is connected to the transmission belt.

[0016] By adopting the above technical solution, the two drive wheels are rotated by the drive motor, which in turn causes the two transmission belts to run and drive the sliding seat to move, thus realizing the transfer and movement of the tooling.

[0017] Optionally, each set of transport rails may have two rails spaced apart to mate with the rail wheels.

[0018] By adopting the above technical solution and setting two tracks at intervals, it is beneficial to improve the support stability of the sliding seat.

[0019] Optionally, the second power unit includes a cylinder mounted on a sliding seat, which drives the lifting platform to move up and down.

[0020] By adopting the above technical solution, the lifting platform is driven to rise and fall by a cylinder. The structure is simple and reliable, and the lifting platform operates smoothly.

[0021] Optionally, a scissor lift mechanism is provided between the sliding seat and the lifting platform.

[0022] By adopting the above technical solution and setting the scissor lift mechanical structure, the scissor lift structure is simple in design, easy to maintain and operate, the lifting process is smooth and has high stability, and can withstand greater complexity.

[0023] Optionally, limit baffles are provided at both ends of the transport rail frame, and anti-collision blocks are provided at both ends of the sliding seat.

[0024] By adopting the above technical solution, the movement limit position of the sliding seat can be restricted by setting limit baffles and anti-collision blocks to prevent derailment.

[0025] In summary, this application includes at least the following beneficial effects: This application achieves workpiece conveying through the installation of loading and unloading roller conveyors. By using a tooling transfer track in conjunction with a conveying mechanism, tooling on the unloading roller conveyor can be lifted and transferred to the other end of the tooling transfer roller conveyor, or tooling on one end of the transfer roller conveyor can be lifted and transferred to the loading roller conveyor. This realizes the circulation of tooling, eliminating the need for manual operation, reducing labor costs, increasing tooling turnover speed, allowing the shot blasting machine to operate at maximum efficiency, meeting the production needs of upstream and downstream production lines, increasing production speed, and improving production efficiency.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] The following is in conjunction with the appendix Figures 1 to 7 This application will be described in further detail.

[0037] This application discloses a loading and unloading transfer device for a shot blasting machine.

[0038] Reference Figures 1 to 7 A loading and unloading transfer device for a shot blasting machine includes: a loading roller conveyor 1, a unloading roller conveyor 2, a tooling transfer roller conveyor 3, and a conveying mechanism.

[0039] The feeding roller conveyor 1 is set at the feeding end of the shot blasting machine 8 and is used to convey the tooling (the workpiece is placed on the tooling) to the shot blasting machine 8.

[0040] The feeding roller conveyor 2 is located at the feeding end of the shot blasting machine 8 and is used to transport the workpieces output from the shot blasting machine 8.

[0041] The tooling conveyor 3 is used to convey tooling in the opposite direction to the loading roller conveyor 1 and the unloading roller conveyor 2. It is set on one side of the loading roller conveyor 1 and the unloading roller conveyor 2, parallel to the loading roller conveyor 1 and the unloading roller conveyor 2.

[0042] The conveying mechanism is provided with five (this embodiment only describes five, but the actual number can be set as needed). One end of the tooling transfer roller conveyor 3 is connected to the loading roller conveyor 1 through three conveying mechanisms, and the other end of the tooling transfer roller conveyor 3 is connected to the unloading roller conveyor 2 through two conveying mechanisms, so as to ensure that the tooling between different roller conveyors is transferred through the conveying mechanism.

[0043] The feeding roller conveyor 1 has three feeding stations 4, with three conveying mechanisms located at the feeding stations 4. The unloading roller conveyor 2 has two unloading stations 5, with two conveying mechanisms located at the unloading stations 5. This connects to the steel produced by the three upstream production lines 6 and the copper material required by the two downstream production lines 7. The steel produced by the upstream production line 6 can be placed on the tooling in the feeding station 4 and fed to the shot blasting machine 8 via the feeding roller conveyor 1. After shot blasting, the tooling is conveyed to the unloading station 5 via the unloading roller conveyor 2. The workpiece on the tooling can be removed to provide steel for the corresponding downstream production line 7. Subsequently, the tooling in the unloading station 5 can be transferred by the conveying mechanism to the tooling transfer roller conveyor 3. The tooling transfer roller conveyor 3 transports the tooling in the opposite direction to one side of the corresponding feeding station 4. Then, the conveying mechanism lifts the tooling and transfers it to the feeding station 4 of the feeding roller conveyor 1, completing the tooling circulation cycle.

[0044] The conveying mechanism includes a conveying base frame. The conveying base frame is horizontally arranged between the tooling transfer roller conveyor 3 and the loading roller conveyor 1, and between the tooling transfer roller conveyor 3 and the unloading roller conveyor 2.

[0045] The transport frame includes two sets of spaced-apart transport rails 9, each set of which a sliding seat 11 is supported by a wheel 10. Each set of transport rails 9 has two spaced-apart tracks 12 that mate with the wheel 10. Through the arrangement of the transport rails 9, the sliding seat 11 can be supported on the transport rails 9 by the wheel 10, enabling the sliding seat 11 to move along the transport rails 9. The spaced-apart tracks 12 improve the stability of the support for the sliding seat 11. The two sets of transport rails 9 allow the two sliding seats 11 to slide, thus enabling two lifting platforms 16 to simultaneously support the movement of the tooling, further improving the stability of the tooling transfer.

[0046] The sliding seat 11 is moved by a first power unit, which includes a drive motor 13 located at the end of the transport rail frame 9. The drive motor 13 drives the driving wheel to rotate. The two ends of the transport rail frame 9 are respectively equipped with a driving wheel and a driven wheel. The two sets of driving wheels at the ends of the transport rail frame 9 are coaxially connected by a transmission shaft 14. The driving wheel and the driven wheel are connected by a transmission belt 15. The sliding seat 11 is connected to the transmission belt 15. The drive motor 13 drives the two driving wheels to rotate, which in turn causes the two transmission belts 15 to run, thus moving the sliding seat 11.

[0047] A lifting platform 16 is provided on the sliding seat 11. The lifting platform 16 is driven to lift and lower via a second power unit. The second power unit includes a cylinder 17 mounted on the sliding seat 11. The cylinder 17 drives the lifting platform 16 to lift and lower. The structure of the lifting platform 16 is simple and reliable, and the lifting and lowering operation of the lifting platform 16 is smooth.

[0048] A scissor mechanism 18 is provided between the sliding seat 11 and the lifting platform 16. With the scissor mechanism 18, the scissor structure is simple in design, easy to maintain and operate, and the lifting process is smooth and has high stability, and can withstand greater complexity.

[0049] Limiting baffles 19 are provided at both ends of the transport rail frame 9, and anti-collision blocks are provided at both ends of the sliding seat 11. By setting the limiting baffles 19 and anti-collision blocks, the movement limit position of the sliding seat 11 can be limited to prevent derailment.

[0050] In this application, the installation of the loading roller conveyor 1 and the unloading roller conveyor 2 enables the conveying of workpieces, achieving both loading and unloading. Through the tooling transfer track 12, in conjunction with the conveying mechanism, the tooling on the unloading roller conveyor can be lifted and transferred to the other end of the tooling transfer roller conveyor 3. Alternatively, the tooling on one end of the tooling transfer roller conveyor 3 can be lifted and transferred to the loading roller conveyor 1, thus realizing the circulation of tooling. This eliminates the need for manual operation, reduces labor costs, and increases the tooling circulation speed, allowing the shot blasting machine 8 to maintain maximum efficiency. It also meets the production needs of the upstream and downstream production lines 7, increasing production speed and efficiency.
