[0027] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0028] like Figures 1 to 5As shown, an embodiment of the utility model provides a roller sandblasting device, comprising: a base 1, which is installed on the ground; a sandblasting cylinder assembly 2, which is installed on the upper part of the base 1, and a secondary cylinder 21 is provided on the sandblasting cylinder assembly 2; a supporting roller 3, which is installed on both sides of the outside of the sandblasting cylinder assembly 2; a roller drive assembly 4, which is installed on the upper part of the base 1; a sandblasting assembly, which comprises: a main air pipe 5, a sandblasting head 6, and a sand storage tank 7, the main air pipe 5 is installed in the secondary cylinder 21, the sandblasting head 6 is installed on the main air pipe 5 at intervals, and the sandblasting head 6 is connected to the sand storage tank 7 through a hose 8; wherein the sandblasting cylinder assembly 2 comprises an upper cylinder 22 and a lower cylinder 23, the upper cylinder 22 and the lower cylinder 23 are connected by a hinge, and the upper cylinder 22 is connected to the base 1 through an opening and closing cylinder 9.

[0029] Before sandblasting, first pull the upper cylinder 22 through the opening and closing cylinder 9 to rotate and open it, then move the roller shaft to the lower cylinder 23 through the overhead crane, so that both ends of the roller shaft are mounted on the support roller 3, and the support roller 3 is connected to the base 1 through the bearing seat, so that the roller shaft is supported by the support roller 3 and the roller shaft can rotate, and then the roller shaft drive assembly 4 is connected to the roller shaft by adjusting the three-jaw chuck 41. The roller shaft drive assembly 4 adopts the existing technology, and a motor and a reducer are arranged inside it, and then the roller shaft is driven by the motor to rotate, so as to realize sandblasting of the outer periphery of the roller shaft.

[0030] During sandblasting, the compressed air from the high-pressure air source is diverted to each sandblasting head 6 through the main air pipe 5, and the airflow is accelerated in the Venturi portion 14 in the sandblasting head 6 and produces a Venturi effect, so that the air pressure in the throat portion is lower than the atmospheric pressure. When the hose 8 is connected to the throat portion of the Venturi portion 14, the hose 8 can inhale air. Since the hose 8 is inserted into the sand storage tank 7, the corundum can be inhaled into the hose 8 along with the air and enter the sandblasting head 6. After being accelerated by the high-speed airflow, it hits the outer periphery of the roller shaft to achieve the purpose of frosting treatment. During sandblasting, the reciprocating push rod 11 reciprocates, thereby driving the sandblasting head 6 to move through the main air pipe 5, and cooperating with the rotation of the roller shaft to complete the sandblasting treatment of the outer periphery of the roller shaft.

[0031] Specifically, both ends of the main air pipe 5 are closed, the middle part of the main air pipe 5 is connected to the high-pressure air source, the compressed air is diverted to the sandblasting head 6 through the main air pipe 5, and the main air pipe 5 is slidably connected to the auxiliary cylinder 21 to facilitate the movement of the main air pipe 5 in the auxiliary cylinder 21.

[0032] Preferably, if Figure 2 As shown, a limit block 10 is provided on the outer periphery of the main air pipe 5, and a groove corresponding to the limit block 10 is provided on the secondary tube 21. The main air pipe 5 is slidably connected to the secondary tube 21 through the limit block 10. The main air pipe 5 is limited by the limit block 10 so that the main air pipe 5 can only slide axially but cannot rotate.

[0033] In a specific embodiment, a reciprocating push rod 11 is provided at one end of the main air pipe 5, one end of the reciprocating push rod 11 is coaxially connected to the main air pipe 5, and the other end of the reciprocating push rod 11 is connected to the base 1 through a connecting seat 12. The reciprocating push rod 11 adopts pneumatic, electric or hydraulic methods to drive the main air pipe 5 to reciprocate, and then drives the sandblasting head 6 to move, so that the sandblasting head 6 can evenly sandblast the outer surface of the roller.

[0034] In a preferred embodiment, a three-jaw chuck 41 is provided on the roller drive assembly 4, and the roller is connected via the three-jaw chuck 41, so that the three-jaw chuck 41 can drive the roller to rotate to achieve sandblasting on the periphery of the roller.

[0035] Preferably, if Figure 4 As shown, an opening is provided at the lower part of the lower cylinder 23, and a sand receiving groove 13 is provided at the lower part of the opening. After the diamond sand is finished sandblasting, it enters the sand receiving groove 13 from the lower opening of the lower cylinder 23 for recycling.

[0036] Preferably, if Figure 5 As shown, a Venturi portion 14 is provided in the sandblasting head 6, and a hose 8 is connected to the throat of the Venturi portion 14. The throat of the middle portion of the Venturi portion 14 contracts and becomes smaller, and the airflow is accelerated when passing through the throat, resulting in a Venturi effect, so that the air pressure in the throat portion is lower than the external atmospheric pressure. After the hose 8 is connected to the throat portion of the Venturi portion 14, the hose 8 can inhale air. Since the hose 8 is inserted into the sand storage tank 7, the corundum can be inhaled into the hose 8 along with the air and enter the sandblasting head 6, and after being accelerated by the high-speed airflow, it hits the outer periphery of the roller shaft, thereby achieving the purpose of sanding treatment.

[0037] Preferably, brushes are provided at the openings on both sides of the upper cylinder 22 and the lower cylinder 23 to seal the gap between the sandblasting cylinder assembly 2 and the roller shaft to prevent diamond sand from splashing from the gap to the outside of the sandblasting cylinder assembly 2.

[0038] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
