[0035] This utility model proposes an intermittent feeding mechanism for a tracked shot blasting machine.
[0036] Before going into detail, it's necessary to understand the application scenario of this utility model: In traditional polishing processes, most equipment uses a tracked, rotating mechanism. Existing tracked shot blasting machines typically employ a manual, continuous feeding method, where workpieces are continuously fed into the shot blasting chamber via a conveyor belt or vibrating feeder. While this feeding method offers high production efficiency, it easily leads to uneven stacking, especially when processing large or complex-shaped workpieces. It often makes it difficult to ensure uniform surface treatment and achieves automated control, thus affecting the subsequent shot blasting effect. For parts with high requirements, uneven stress often causes damage, impacting the shot blasting effect and processing accuracy. Therefore, an intermittent feeding mechanism for a tracked shot blasting machine is proposed.
[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0038] like Figure 1-4 The diagram shown is a schematic representation of the overall structure of this utility model:
[0039] It should be clear that the fixed seat 1, made of sturdy metal material, is symmetrically installed on the bracket 15 of the shot blasting machine. It is used to support the entire intermittent feeding mechanism. The bearing seat (2) is fixed to the fixed seat (1) by bolts, providing support for the first rotating shaft (3) and the second rotating shaft (4), and the first rotating shaft (3) and the second rotating shaft (4) rotate within the bearing seat (2). The first rotating shaft (3) and the second rotating shaft (4) are respectively set in two symmetrical bearing seats (2) for connecting the L-shaped connecting rod (5) and the C-shaped rod (9) to rotate. The L-shaped connecting rod (5) is connected to the first rotating shaft (3) at the corner, and the first end of the L-shaped connecting rod (5) is hinged to the cylinder (6), and the second end is hinged to the first connecting rod (7). The cylinder (6) is used to drive the L-shaped connecting rod (5) to rotate. The other end of the first connecting rod (7) is hinged to the second connecting rod (8). The two C-shaped rods (9) are shaped like a "C" and are set opposite each other. They are respectively engaged with the first rotating shaft (3) and the second rotating shaft (4). They can rotate under the rotation of the first rotating shaft (3) and the second rotating shaft (4) to open and close and block the movement of the workpiece.
[0040] In use, the cylinder (6) is activated, causing its telescopic rod to extend outward, which in turn drives the L-shaped connecting rod (5) and the first rotating shaft (3) to rotate. The rotation of the first rotating shaft (3) drives the C-shaped rod (9) to rotate, causing the C-shaped rod (9) connected to it to block the workpiece in front of it, preventing the workpiece from moving. At the same time, the L-shaped connecting rod (5) rotates and pulls the first connecting rod (7), which transmits force to the second connecting rod (8). The second connecting rod (8) rotates and drives the second rotating shaft (4) to rotate, so that the second rotating shaft (4) follows the first rotating shaft (3) to rotate. The C-shaped rod (9) connected to the second rotating shaft (4) rotates, further blocking the workpiece from moving. When the telescopic rod of the cylinder (6) retracts, the L-shaped connecting rod (5) and the first rotating shaft (3) return to their original positions, and the C-shaped rod (9) returns to its initial position, allowing the workpiece to continue moving forward.
[0041] Furthermore, there are two C-shaped rods (9), each of which has a head end (10), a tail end (11), and a middle section (12). The head end (10) and the tail end (11) are located at the two ends of the C-shaped rod (9), respectively.
[0042] The middle section (12) is the main body of the C-shaped rod (9), and its length can be adjusted according to actual needs. The two middle sections (12) are connected to the first rotating shaft (3) and the second rotating shaft (4) respectively. When the two ends (10) are engaged, there is space between the two C-shaped rods (9) to accommodate the workpiece. When the two ends (11) are engaged, the ends (10) are disengaged, and the workpiece moves forward under the drive of the track and enters the processing area.
[0043] It should be noted that if the distance between the two ends (11) is further set so that the distance between the two ends (10) is less than the size of the workpiece to be passed when the distance between the two ends (11) is the greatest, then the two ends (10) will be joined together to form a limiting mechanism. The workpiece will move forward under the drive of the track, and will stop when it reaches the middle of the two ends (10) under the limiting action of the two ends (10).
[0044] Furthermore, connection points are set at the midpoints of the two middle sections 12, which are respectively connected to the first rotation axis 3 and the second rotation axis 4. This design ensures the balance and stability of the C-shaped rod (9) during rotation. The longitudinal section of the C-shaped rod (9) is I-shaped, which has high strength and stiffness and is suitable for bearing large loads.
[0045] It should be noted that, in order to further improve the smoothness of the operation of the C-shaped rod (9), rollers (13) are provided at both its first end (10) and its last end (11). The rollers (13) enable the material to pass through smoothly during the feeding process, reduce the resistance of the material during the feeding process, effectively protect the C-shaped rod (9), and improve the feeding efficiency.
[0046] Furthermore, a rubber anti-slip layer is provided on the outer surface of the roller (13), the shape of which matches the outer surface of the roller (13). The rubber anti-slip layer and the roller (13) can be bonded together with an adhesive to ensure that it does not easily fall off during use. The rubber anti-slip layer can enhance the gripping force of the workpiece during contact and also protect the roller 13.
[0047] It is worth noting that the transmission track (14), as the main transmission mechanism for the shot blasting machine workpiece, is generally a rubber track. It consists of three layers, with the outer layer covered by rubber. It is in direct contact with the finished workpiece and bears the impact of steel shot, so it wears severely and is subjected to great destructive force. The lifespan of the rubber covering is the lifespan of the track.
[0048] Furthermore, the bracket 15 supports the drive track (14) and the fixed seat 1. Its shape and size are designed according to the actual application environment to ensure sufficient stability and load-bearing capacity. The drive track (14) is mounted on the bracket 15 for driving and transmitting power. The mounting of the drive track (14) on the bracket 15 ensures the stability and reliability of the drive track (14) during movement. The fixed seat (1) is mounted on the bracket 15 for mounting and fixing other equipment or components. The fixed seat (1) is fixedly connected to the bracket 15, such as by welding or screws, to ensure the stability and reliability of the fixed seat (1) during movement.
[0049] It should be noted that the above embodiments are merely one specific implementation of this utility model and are not limited to the described embodiments. For those skilled in the art, various changes and modifications can be made without departing from the spirit and scope of the technical solution of this utility model, and these should all be included within the protection scope of this utility model.
[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
