DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] See also Figure 1-Figure 5 The utility model provides a technical solution: a feeding device for mechanical processing, comprising a bracket 1, a motor 2 is installed on one side of the bracket 1, a feeding belt 3 is arranged on the upper surface of the bracket 1, and limiting components are respectively arranged on both sides of the feeding belt 3, the limiting components include a slider 13, a first push rod 14 and a second push rod 21, the limiting components are used to limit the workpiece above the feeding belt 3, one side of the slider 13 is connected to a connecting spring 12, and the other end of the connecting spring 12 is connected to a fixing block 11;
[0035] It is worth mentioning that when the workpiece is fed by the feeding belt 3, the limiting assembly can push the workpiece on the feeding belt 3 so that the workpiece is located in the middle position of the feeding belt 3, thereby preventing the workpiece from colliding and rubbing with the inner wall of the device during the feeding process.
[0036] See also Figure 1-Figure 2 A closing component is provided on the lower surface of the fixed block 11, and the closing component includes a rack 22, a second gear 23, a connecting shaft 24 and a baffle 25. The rack 22 is fixedly connected to the fixed block 11, the connecting shaft 24 passes through the second gear 23 and is fixedly connected thereto, the baffle 25 is sleeved on the outer surface of the connecting shaft 24, and the closing component is used to close the feed port of the feeding belt 3. The connection mode of the connecting shaft 24 and the bracket 1 is a rotational connection, and the baffle 25 is symmetrically distributed about the longitudinal center line of the feeding belt 3.
[0037] The principle of closing the feed port of the feeding belt 3 is as follows: when the fixed block 11 moves toward the center of the feeding belt 3, it will drive the rack 22 to move synchronously toward the center of the feeding belt 3, and the rack 22 will push the second gear 23 to rotate. The second gear 23 drives the baffle 25 to rotate through the connecting shaft 24, and the baffle 25 closes the feed port of the feeding belt 3 by rotating. At this time, the workpiece cannot enter the feeding belt 3 through the feed port, which is helpful to avoid a large number of workpieces from accumulating on the feeding belt 3. Similarly, when the fixed block 11 moves toward the outside of the feeding belt 3, it will drive the rack 22 to move synchronously toward the outside of the feeding belt 3, and the rack 22 will push the second gear 23 to rotate in the opposite direction. The second gear 23 drives the baffle 25 to rotate in the opposite direction through the connecting shaft 24, thereby opening the feed port of the feeding belt 3. At this time, the workpiece can enter the feeding belt 3 through the feed port for feeding.
[0038] See also Figure 1-Figure 6 A rotating shaft 4 is connected to one side of the motor 2, and a half gear 5 is fixedly connected to one end of the rotating shaft 4. A first gear 6 is meshed and connected to one side of the half gear 5. A reciprocating screw rod 7 is fixedly connected to one side of the first gear 6. A limiting plate 8 is sleeved on the outer surface of the reciprocating screw rod 7. A support rod 10 is fixedly connected to one side of the fixed block 11. The lower end of the support rod 10 is connected to the limiting plate 8, and a guide shaft 9 runs through the interior of the limiting plate 8.
[0039] The principle of limiting the workpiece is: the motor 2 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the first gear 6 to rotate through the half gear 5, and the first gear 6 drives the reciprocating screw 7 to rotate. Since the connection mode of the reciprocating screw 7 and the limiting plate 8 is a threaded connection, the reciprocating screw 7 can drive the limiting plate 8 to reciprocate back and forth by rotating. When the limiting plate 8 drives the fixed block 11 to move toward the center of the feeding belt 3 through the support rod 10, the slider 13 inside the fixed block 11 drives the first push rod 14 and the second push rod 21 to move toward the center of the feeding belt 3 synchronously. The first push rod 14 and the second push rod 21 push the workpiece to move toward the center of the feeding belt 3, thereby ensuring that the workpiece is located in the middle position of the feeding belt 3, which is beneficial to avoid the workpiece from colliding and rubbing with the inner wall of the device during the feeding process.
[0040] See also Figure 1-Figure 5 The slider 13 forms a telescopic structure inside the fixed block 11 through the connection spring 12, and the connection mode between the slider 13 and the fixed shaft 15 is a fixed connection.
[0041] It is worth mentioning that the sliding block 13 can drive the first push rod 14 to extend and retract on one side of the fixed block 11, so that the first push rod 14 can push workpieces of different sizes to limit their positions.
[0042] See also Figure 1-Figure 5The first push rod 14 is fixedly connected to the slider 13, a fixed shaft 15 is provided on one side of the slider 13, a sliding shaft 16 is provided inside the fixed shaft 15, the upper end of the sliding shaft 16 is connected to the second push rod 21, the centers of the first push rod 14 and the second push rod 21 are located on the same vertical line, and the first push rod 14 and the second push rod 21 are symmetrically distributed about the longitudinal center line of the feeding belt 3.
[0043] It is worth mentioning that the design of two push rods can increase the contact area between the push rod and the workpiece, making it easier for the push rod to push the workpiece to move.
[0044] See also Figure 4-Figure 6 A slide slot 17 is provided inside the slide shaft 16, a return spring 18 is provided inside the slide slot 17, one end of the return spring 18 is connected to a clamping block 19, and a clamping slot 20 is provided on the outer surface of the fixed shaft 15 at equal distances;
[0045] The principle of adjusting the height of the second push rod 21 is: first, push the block 19 into the inside of the slide groove 17 so that the block 19 is separated from the slot 20. At this time, the return spring 18 is squeezed and compressed, and then the sliding shaft 16 is pulled to make it slide inside the fixed shaft 15, so that the height of the second push rod 21 can be adjusted, which is convenient for the first push rod 14 and the second push rod 21 to meet the limit requirements of workpieces of different heights. Then release the block 19, and the return spring 18 pushes the block 19 to move in the opposite direction for reset, and the block 19 is engaged and connected with the slot 20, so that the sliding shaft 16 and the fixed shaft 15 are stably connected.
