Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a crawler type shot blasting machine for hinge production. Background Art

[0002] The crawler shot blasting machine mainly includes a shot blasting machine body, a shot blasting chamber is arranged inside the shot blasting machine body, a feeding port connected to the shot blasting chamber is opened on the front side of the shot blasting machine body, a concave cavity is made of rubber crawler inside the shot blasting chamber as a carrier of the workpiece, and the shot blaster arranged on the top of the shot blasting chamber uses a high-speed rotating impeller to project the shot onto the tumbling workpiece, so that the inner and outer surfaces of the workpiece are cleaned. It is mainly suitable for small castings and forgings, such as hinges on containers, stamping springs, etc., to remove sand and rust;

[0003] In the process of feeding the castings and forgings into the shot blasting chamber through the feed port, it is necessary to first use a cylinder to drive the baffle to open the feed port, and then use a motor to drive the hopper containing the castings and forgings to rotate, so that the castings and forgings enter the shot blasting chamber. Most of the shot blasting machines currently in use cannot automatically synchronize the feeding of the hopper with the opening and closing of the feed port door panel, so that the two work processes are driven and operated separately using separate power sources, which is not conducive to improving the feeding efficiency of the shot blasting machine. In addition, the hopper generally only has the function of holding materials, and it is not easy to control the feeding amount of castings and forgings. Utility Model Content

[0004] The purpose of the utility model is to provide a crawler shot blasting machine for hinge production to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A crawler shot blasting machine for hinge production comprises a shot blasting machine body, a shot blasting chamber is arranged inside the shot blasting machine body, a shot blasting device is fixedly installed on the inner top of the shot blasting chamber, a feeding port connected to the shot blasting chamber is opened on the front side of the shot blasting machine body, a plurality of rollers are rotatably connected inside the shot blasting chamber, a crawler for carrying workpieces is transmission-connected between the plurality of rollers, a hopper is arranged on the front side of the feeding port, a feeding mechanism for controlling the feeding amount is arranged inside the hopper, transmission arms slidably connected to the shot blasting machine body are rotatably connected on both sides of the hopper, an arc seat is fixed on one side of the shot blasting machine body, an arc rack for driving the hopper to rotate and feed is slidably connected to the inner side of the arc seat, and a motor 2 for driving the arc rack to rotate is fixed on the outer side of the shot blasting machine body.

[0007] Furthermore, the material unloading mechanism includes a motor 1 fixedly connected to the hopper, a connecting shaft is fixed to the output end of the motor 1, the connecting shaft is rotatably connected to the hopper, and a plurality of material-discharging plates are fixed at equal angles in a ring shape on the outer side of the connecting shaft.

[0008] Furthermore, universal wheels are fixedly mounted on both ends of the bottom surface of the hopper, and a gap is reserved between the unloading mechanism and the hopper.

[0009] Furthermore, a trapezoidal sliding block is fixed on the inner side of the transmission arm, trapezoidal sliding grooves are provided on both sides of the shot blasting machine body, and the trapezoidal sliding block is slidably engaged with the trapezoidal sliding grooves at corresponding positions.

[0010] Furthermore, a reduction motor for driving a roller at a corresponding position to rotate is fixed on the outer side of the shot blasting machine body, and a gap exists between the hopper and the feed inlet.

[0011] Furthermore, a gear meshing with the arc-shaped rack is fixed to the output end of the second motor, and a transmission shaft is fixed to the bottom end of the arc-shaped rack.

[0012] Furthermore, a long groove-shaped limiting ring is fixed on one side of the bottom of the hopper, and the transmission shaft is slidably engaged with the limiting ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Motor 2 rotates with the gear to make the arc rack drive the hopper to rotate counterclockwise along the center of the arc rack, so that the vertically arranged hopper rotates to tilt toward the feed port, which is convenient for the hopper to release the castings and forgings into the shot blasting room. Then motor 2 rotates with the gear in the opposite direction to make the arc rack drive the hopper to rotate clockwise. When the universal wheel at the bottom of the hopper touches the ground, the gear continues to reversely drive the arc rack to rotate clockwise, so that the hopper moves toward the feed port along the trapezoidal chute, so that the rear side of the hopper is blocked in front of the feed port to close the feed port, which is convenient for the two working processes of casting and forging feeding and closing the feed port to be driven by one power source of motor 2, and the two are combined to improve the feeding efficiency of the shot blasting machine.

[0015] 2. The motor drives the connecting shaft to rotate to rotate multiple material-discharging plates, so that when the hopper is arranged at an angle, the material-discharging plates can uniformly transport the castings and forgings to the crawler belt of the shot blasting chamber. When the motor stops rotating with the connecting shaft, the hopper stops releasing the castings and forgings, which is convenient for controlling the hopper to put an appropriate amount of castings and forgings into the shot blasting chamber each time, so as to facilitate the efficient cleaning of castings and forgings in the shot blasting chamber.

DETAILED DESCRIPTION

[0023] 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.

[0024] Embodiment 1

[0025] See also Figure 1-6 In the embodiment of the utility model, a crawler shot blasting machine for hinge production is provided, the shot blasting machine body 100, a shot blasting chamber is arranged inside the shot blasting machine body 100, a shot blasting machine is fixedly installed on the inner top of the shot blasting chamber, a feeding port 110 connected to the shot blasting chamber is opened on the front side of the shot blasting machine body 100, a plurality of rollers are rotatably connected inside the shot blasting chamber, a crawler 120 for carrying workpieces is transmission-connected between the plurality of rollers, a hopper 200 is arranged on the front side of the feeding port 110, a feeding mechanism 210 for controlling the feeding amount is arranged inside the hopper 200, transmission arms 220 slidably connected to the shot blasting machine body 100 are rotationally connected on both sides of the hopper 200, an arc seat 300 is fixed on one side of the shot blasting machine body 100, an arc rack 400 for driving the hopper 200 to rotate and feed is slidably connected to the inner side of the arc seat 300, and a motor 2 500 for driving the arc rack 400 to rotate is fixed on the outer side of the shot blasting machine body 100.

[0026] Specifically, the motor 2 500 drives the gear 510 to rotate so that the arc-shaped rack 400 drives the hopper 200 to rotate and tilt, and the motor 1 211 drives the unloading mechanism 210 to operate so that the hopper 200 evenly and controllably releases the castings and forgings into the shot blasting chamber. After the castings and forgings are released, the gear 510 drives the hopper 200 in reverse to rotate to a vertical state, and then the gear 510 continues to drive the arc-shaped rack 400 to move the hopper 200, so that the hopper 200 slides toward the feed port 110, and then the hopper 200 can block the feed port 110, thereby combining the feeding of the castings and forgings with the blocking of the feed port 110, thereby improving the feeding efficiency of the shot blasting machine body 100. In addition, the hopper 200 can not only use the unloading mechanism 210 to control the amount of castings and forgings released into the shot blasting chamber, but also block the feed port 110, thereby improving the versatility of the hopper 200.

[0027] like Figure 5 As shown, in this embodiment, universal wheels 240 are fixedly installed at both ends of the bottom surface of the hopper 200, and a gap is reserved between the unloading mechanism 210 and the hopper 200. The universal wheels 240 can effectively reduce the resistance between the hopper 200 and the ground when the arc-shaped rack 400 drives the hopper 200 to move toward the feed port 110, and the gap facilitates the delivery of castings and forgings into the hopper 200.

[0028] like Figure 3 and Figure 5 As shown, in this embodiment, a trapezoidal slider 221 is fixed to the inner side of the transmission arm 220, and trapezoidal slide grooves 140 are provided on both sides of the shot blasting machine body 100. The trapezoidal slider 221 is slidably engaged with the trapezoidal slide grooves 140 at the corresponding position. In the initial state, the motor 2 500 rotates with the gear 510 to rotate the arc rack 400 counterclockwise, so that the transmission arm 220 on the hopper 200 slides along the trapezoidal slide groove 140 toward the feeding port 110, and the universal wheel 240 rolls on the ground.

[0029] like Figure 2 As shown, in this embodiment, a reduction motor 130 for driving the corresponding position roller to rotate is fixed on the outside of the shot blasting machine body 100, and there is a gap between the hopper 200 and the feed port 110. The reduction motor 130 drives the roller to rotate to drive the crawler 120, thereby turning the material on the crawler 120, so that the shot blasting fully contacts the casting and forging, and the gap meets the rotation space requirements of the hopper 200.

[0030] like Figure 5 and Figure 6 As shown, in this embodiment, the output end of the motor 2 500 is fixed with a gear 510 meshing with the arc-shaped rack 400, the bottom end of the arc-shaped rack 400 is fixed with a transmission shaft 410, and a long groove-shaped limiting ring 230 is fixed on one side of the bottom of the hopper 200, and the transmission shaft 410 is slidably engaged with the limiting ring 230.

[0031] In this embodiment, the motor 2 500 rotates with the gear 510 to enable the arc rack 400 to slide along the arc seat 300, thereby driving the hopper 200 to move. The length of the limit ring 230 is greater than the diameter of the transmission shaft 410. Figure 1 In the initial state, the rotation position of the hopper 200 and the transmission arm 220 is in line with the center of the arc rack 400. At this time, the counterclockwise rotation of the arc rack 400 will cause the transmission shaft 410 to rotate counterclockwise along the center of the circle with the hopper 200 through the limit ring 230, so that the vertical hopper 200 rotates and tilts to discharge materials. In the initial state, if the gear 510 rotates clockwise with the arc rack 400, the transmission shaft 410 will cause the hopper 200 to rotate counterclockwise along the center of the circle through the limit ring 230. 00 moves toward the feeding port 110. At this time, the rotation positions of the hopper 200 and the transmission arm 220 are no longer in line with the center of the arc-shaped rack 400. At the same time, the universal wheel 240 on the bottom of the hopper 200 is in contact with the ground. As the arc-shaped rack 400 rotates counterclockwise, the hopper 200 moves to block the feeding port 110. During this process, the transmission shaft 410 will move slightly upward along the limit ring 230, meeting the need for the transmission shaft 410 to move upward as the arc-shaped rack 400 drives it.

[0032] When implementing it, refer to the instructions in the initial state. Figure 1 , the external castings and forgings are put into the hopper 200 from below the material-dispensing plate 212. When loading, the motor 2 500 drives the gear 510 to rotate so that the arc-shaped rack 400 drives the hopper 200 to rotate counterclockwise, so that the opening of the hopper 200 rotates toward the position of the crawler 120 inside the inlet 110, and then the motor 1 211 drives the connecting shaft to rotate so that the multiple material-dispensing plates 212 rotate so that the castings and forgings inside the hopper 200 are released onto the crawler 120. After the loading is completed, the motor 2 500 drives the arc-shaped rack 400 to rotate in the opposite direction to rotate the hopper 200. To the initial position, at this time, the universal wheel 240 on the bottom of the hopper 200 contacts the ground, and as the arc rack 400 continues to rotate clockwise, the hopper 200 moves toward the feed port 110. At this time, the universal wheel 240 rolls on the ground, and the hopper 200 blocks the feed port 110. Then the reduction motor 130 rotates with the roller to make the crawler 120 flip the castings and forgings. The shot blaster inside the shot blasting machine body 100 releases shots to the castings and forgings, and the castings and forgings are shot blasted. The specific working principle of the shot blasting machine body 100 is the existing technology and will not be repeated.

[0033] Embodiment 2

[0034] On the basis of the first embodiment, in order to make the hopper 200 evenly and controllably put the castings and forgings into the shot blasting machine body 100.

[0035] like Figure 5As shown, in this embodiment, the unloading mechanism 210 includes a motor 211 fixedly connected to the hopper 200, and a connecting shaft is fixed to the output end of the motor 211. The connecting shaft is rotatably connected to the hopper 200, and a plurality of material discharging plates 212 are fixed at equal angles in a ring shape on the outer side of the connecting shaft.

[0036] Specifically, the motor 211 rotates with the connecting shaft to rotate the multiple material stripping plates 212. When the hopper 200 is tilted toward the track 120 to feed materials, as the material stripping plates 212 rotate, the castings and forgings can be evenly delivered to the shot blasting chamber. When a proper amount of castings and forgings are delivered to the track 120 of the shot blasting chamber, the motor 211 is stopped from rotating with the multiple material stripping plates 212 on the connecting shaft to prevent excessive castings and forgings from being delivered to the track 120 of the shot blasting chamber.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
