Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, and in particular to a hot-dip galvanized drum sandblasting machine. Background Technology

[0002] The surfaces of various equipment or hot-dip galvanized workpieces usually need to be sandblasted. The working principle of sandblasting is to use compressed air as power to form a high-speed jet to spray sand at high speed onto the surface of the equipment or hot-dip galvanized workpiece to be sandblasted, thereby changing the mechanical properties of the surface. Due to the impact and cutting action of the sand on the surface, the surface gains a certain degree of cleanliness and roughness, which greatly improves the mechanical properties, enhances fatigue resistance, increases the adhesion between the surface and the coating, and extends the service life of the equipment or hot-dip galvanized workpiece.

[0003] When treating the surface of the roller, it is necessary to use a sandblasting machine to sandblast the roller. In order to ensure the uniformity of the coating, the roller needs to be rotated during the sandblasting process. Furthermore, feeding, sandblasting, and unloading are usually carried out in a cycle at one station, which seriously affects the work efficiency. Utility Model Content

Detailed Implementation

[0025] Example 1

[0026] like Figures 1-4 As shown in the figure, the hot-dip galvanizing roller sandblasting machine proposed in this embodiment includes a frame 1, a horizontal plate 9, a push plate 13, a sandblasting mechanism, an automatic reset mechanism, and multiple sets of material feeding components.

[0027] A transmission belt 2 is mounted on a frame 1, and a drive assembly for driving the transmission belt 2 is also mounted on the frame 1. The drive assembly includes a servo motor 5 and transmission rollers 4. Multiple transmission rollers 4 are arranged side by side and are rotatably mounted on the frame 1. The transmission belt 2 is sleeved on the outer periphery of the multiple transmission rollers 4. The servo motor 5 is mounted on the frame 1 and its output shaft is connected to the rotating shaft of the transmission roller 4. In order to improve the transmission effect, the number of servo motors 5 is not limited to one, but can also be multiple. The multiple servo motors 5 are used to drive the multiple transmission rollers 4 to rotate, and the main function of the multiple transmission rollers 4 located in the middle is to support the upper end of the transmission belt 2.

[0028] The feeding assembly includes two supports 12 mounted side by side on the transmission belt 2. Each support 12 has a notch 121 with a semi-circular cross-section. A base plate 20 is connected between the two opposing supports 12. The base plate 20 prevents the high-speed sand particles ejected from directly hitting the surface of the transmission belt 2, thus avoiding damage to the transmission belt 2. A horizontal plate 9 is positioned above one side of the transmission belt 2 and connected to the frame 1.

[0029] The sandblasting mechanism includes a sandblasting machine 3, a sliding frame 7, and a sandblasting head 8. The sandblasting machine 3 is located on one side of the frame 1. The sliding frame 7 is slidably mounted on the upper end of the frame 1. An elastic band 6 connects the sliding frame 7 to the end of the frame 1. The sandblasting head 8 is mounted on the sliding frame 7. The output end of the sandblasting machine 3 is connected to the input end of the sandblasting head 8.

[0030] The push plate 13 is mounted on the support 12, and the sliding frame 7 is equipped with a sensor 19. The sensor 19 is a pressure sensor. When the push plate 13 contacts the sensor 19, the sensor 19 feeds back the detection signal to the PLC controller, and the PLC controller controls the sandblasting machine 3 to work.

[0031] The automatic reset mechanism includes a wedge block 17, an elastic connecting assembly, and a vertical plate 10. The vertical plate 10 is connected to the horizontal plate 9. The push plate 13 is slidably mounted on the support 12. The push plate 13 and the support 12 are connected by the elastic connecting assembly. The elastic connecting assembly includes a guide rod 14, a spring 16, and two limit blocks 15. The two limit blocks 15 are arranged side by side on the support 12. The guide rod 14 is connected between the two limit blocks 15. A slider is connected to the push plate 13 and is slidably mounted on the guide rod 14. The spring 16 is sleeved on the guide rod 14. The elastic connecting assembly is used to assist the automatic reset of the push plate 13. The wedge block 17 is set on the push plate 13. Buffer sponges 18 are installed on both sides of the frame 1. When the sliding frame 7 is reset, the buffer sponges 18 can buffer and reduce noise.

[0032] Specifically, when sandblasting a galvanized roller, to ensure the safety of operators, they should wear dustproof clothing, masks, and gloves. First, the two ends of the roller shaft should be placed in the notches 121 on both sides. To ensure smooth rotation of the roller, multiple ball bearings are installed inside the notches 121. The servo motor 5 drives the transmission roller 4 to rotate, which in turn drives the transmission belt 2 to move. During the movement of the transmission belt 2, the roller moves. When the push plate 13 contacts the sliding frame 7, the sliding frame 7 will move during the movement of the support 12. At the same time, the push plate 13 contacts the sensor 19, which is a pressure sensor. The sensor 19 feeds the detection signal back to the PLC controller, which controls the sandblasting machine 3 to work. The sandblasting machine 3 delivers high-speed sand particles to the sandblasting head 8, which then sprays them onto the surface of the roller. As the roller continues to move, when the roller contacts the horizontal plate 9, the roller rotates under the action of friction, thus achieving all-round sandblasting of the roller.

[0033] When the sensor 19 contacts the inclined surface of the wedge block 17, the push plate 13 gradually moves towards the side of the roller under the cooperation of the elastic connecting component. When the push plate 13 separates from the sliding frame 7, the sliding frame 7 is driven to quickly reset under the elastic force of the elastic band 6, which facilitates the sandblasting work of the next set of rollers.

[0034] When the roller moves to the end of the transmission belt 2 and begins to rotate downwards, the roller falls off the unloading assembly under the action of gravity, thus realizing the function of automatic unloading. It should be added that the operator can set up a sponge in the unloading area to play a role in shock absorption and cushioning.

[0035] Example 2

[0036] like Figure 4As shown in the figure, the hot-dip galvanizing roller sandblasting machine proposed in this embodiment, compared with the first embodiment, has a sandblasting head 8 slidably mounted on a sliding frame 7. The sandblasting head 8 is connected to the sandblasting machine 3 through a flexible hose. A reciprocating cylinder 11 for driving the sandblasting head 8 to move back and forth is installed on the sliding frame 7. Multiple sandblasting nozzles are installed side by side on the sandblasting head 8. The reciprocating cylinder 11 can drive the sandblasting head 8 to move back and forth, which can prevent sand particles from concentrating and improve the grinding effect of the roller surface. When the push plate 13 contacts the sensor 19, the PLC controller controls the reciprocating cylinder 11 to work.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
