[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Schematic diagram of the cutting mechanism; Figure 3 This is a schematic diagram of the structure of the rubber sleeve end clamping and sealing mechanism of this utility model; Figure 4 This is a structural schematic diagram of the steel pipe pushing mechanism of this utility model.

[0025] As attached Figure 1 As shown, an automatic roller coating machine includes a machine base 1, a sleeve pushing mechanism 2, a sleeve cutting mechanism 3, a sleeve supporting mechanism 4, a sleeve end clamping and sealing mechanism 5, a sleeve opening opening mechanism 6, a steel pipe pushing mechanism 7, an exhaust mechanism 8, an air pump, and an air valve. The sleeve pushing mechanism 2 and the sleeve cutting mechanism 3 are installed at the feed end of the machine base 1. The sleeve supporting mechanism 4 is installed on the side of the machine base 1. The sleeve end clamping and sealing mechanism 5, the sleeve opening opening mechanism 6, and the steel pipe pushing mechanism 7 are sequentially installed on the machine base 1. The sleeve end clamping and sealing mechanism 5 is installed on the exhaust mechanism 8. The sleeve end clamping and sealing mechanism 5 is connected to the air pump through a pipeline, and an air valve is installed on the pipeline.

[0026] As attached Figure 2 As shown, the rubber sleeve pushing mechanism 2 includes a horizontal roller conveyor 21, a roller 22, and a motor. The output shaft of the motor is fixed with the roller 22, which is located above the horizontal roller conveyor 21.

[0027] When the rubber sleeve passes between the horizontal roller conveyor 21 and the roller 22, the motor drives the roller 22 to rotate, and the roller 22 pushes the rubber sleeve forward.

[0028] The rubber sleeve cutting mechanism 3 includes a cutter and a lifting cylinder, with the cutter fixed on the piston rod of the lifting cylinder. The lifting cylinder can drive the cutter to rise and fall, thereby cutting the rubber sleeve.

[0029] The rubber sleeve support mechanism 4 consists of a horizontal rod 41 and L-shaped brackets 42, with several L-shaped brackets 42 fixed on the horizontal rod 41. The several L-shaped brackets 42 can support a long strip of uninflated rubber sleeve.

[0030] As attached Figure 3 As shown, the rubber sleeve end clamping sealing mechanism 5 includes a connector 51, a retaining ring 52, a connector drive cylinder 53, and a housing 54. The connector 51 is fixed on the piston rod of the connector drive cylinder 53. The cylinder body of the connector drive cylinder 53 and the retaining ring 52 are installed inside the housing 54. The connector 51 passes through the annular hole of the retaining ring 52. The front end of the connector 51 is provided with an air outlet. The connector 51 is connected to an air pump through a pipeline.

[0031] The connector 51 has an octagonal cross-section. First, the connector drive cylinder 53 drives the connector 51 forward, at which point the connector is positioned in front of the retaining ring 52. Next, the operator places one end of the rubber sleeve onto the connector 51, and then the connector 51 moves backward until it returns to the annular hole of the retaining ring 52. At this point, the end of the rubber sleeve is pressed and sealed between the connector 51 and the retaining ring 52. An air pump injects gas into the rubber sleeve through the air outlet of the connector 51, thus fully opening the inner cavity of the rubber sleeve. An air valve controls the air pressure.

[0032] The exhaust mechanism 8 is a cylinder. The piston rod of the cylinder is connected to the housing 54. The cylinder body is fixed on the base plate. The housing 54 is slidably connected to the base plate.

[0033] After the rubber sleeve is fitted onto the steel pipe, there will be residual air between the rubber sleeve and the steel pipe. At this time, the exhaust mechanism 8 drives the rubber sleeve end clamping and sealing mechanism 5, which clamps the end of the rubber sleeve, to move back and forth horizontally. This allows the rubber sleeve to be pulled back and forth, thereby removing the residual air.

[0034] The rubber sleeve opening mechanism 6 includes a frame 61, an arc plate driving cylinder 62, and an arc plate. Three arc plate driving cylinders 62 are fixed on the frame 61. An arc plate is fixed on the piston rod of the arc plate driving cylinder 62. The three arc plates are centrally symmetrical. The frame 61 is provided with a through hole for passing through the steel pipe. The through hole is located between the three arc plates.

[0035] When the three arc-shaped plates come together, they form a circular tube. After one end of the rubber sleeve is placed on the circular tube, the piston rods of the three arc-shaped plates drive cylinder 62 to retract simultaneously, causing the three arc-shaped plates to move outwards respectively, thus opening one end of the rubber sleeve.

[0036] As attached Figure 4As shown, the steel pipe pushing mechanism 7 includes a horizontal linear module 71, a support pipe 72, a base 73, a guide rod 74, a spring 75, a stop block 76, and a support frame 77. The base 73 is fixed on the slide of the horizontal linear module 71, and the support pipe 72 is fixed on the base 73. The front end of the support pipe 72 is provided with a slot for inserting the steel pipe. The guide rod 74 passes through the guide hole on the base 73. The front end of the guide rod 74 is fixed with a stop block 76 and a support frame 77. The support frame 77 is attached to the bottom of the support pipe 72. A spring 75 is provided between the stop block 76 and the base 73.

[0037] One end of the steel pipe is inserted into the slot at the front end of the support pipe 72, and then the horizontal linear module 71 drives the support pipe 72, which carries the horizontal steel pipe, to move forward in a straight line. After the stop block 76 moves forward and contacts the frame 61, the base 73 and the support pipe 72 will continue to move forward along the guide rod 74 until the steel pipe is fully inserted into the rubber sleeve. During the movement of the steel pipe, the support frame 77 on the stop block 76 can effectively provide support for the support pipe 72.

[0038] The working method of this application is as follows: First, the rubber sleeve pushing mechanism 2 drags the rubber sleeve into the machine 1. When the front end of the rubber sleeve contacts the sensor, the sensor transmits a signal to the PLC. The PLC controls the rubber sleeve pushing mechanism 2 to stop operating and controls the rubber sleeve cutting mechanism 3 to cut the rubber sleeve.

[0039] Next, one end of the cut rubber sleeve is fitted onto the rubber sleeve end clamping and sealing mechanism 5 and clamped, while the other end is fitted onto the rubber sleeve opening mechanism 6 to open the opening. Then, the air pump supplies air into the rubber sleeve, so that the inner cavity of the rubber sleeve is fully opened.

[0040] The steel pipe is then fed into the rubber sleeve by the steel pipe pushing mechanism 7. As the steel pipe gradually enters the rubber sleeve, the air valve gradually reduces the air pressure supplied to the rubber pipe to facilitate insertion. After the rubber sleeve and steel pipe are assembled, the exhaust mechanism 8 removes any remaining air between the rubber sleeve and the steel pipe. Finally, the rubber sleeve pushing mechanism 2 pushes the assembled roller out of the machine base 1.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
