Description

Technical Field

[0001] The present application relates to the field of oil-free spider hands, and in particular to a transmission device for an oil-free spider hand of a cigarette making machine. Background Art

[0002] A cigarette making machine is a device for automatically producing cigarettes. It combines tobacco leaves, filter tips and cigarette paper, and through cutting, rolling and packaging, finally forms finished cigarette sticks. After the cigarette sticks are processed and formed in the cigarette making machine, they need to be transported to the packaging position by an oil-free spider hand. The oil-free spider hand is an advanced robotic arm technology, usually used in industrial environments that require high precision and pollution-free operation. Its characteristic is that no grease is used during the operation, thus avoiding the pollution of the product by lubricating oil, and is especially suitable for processing products with strict requirements for cleanliness. By gently transporting the cigarette sticks formed by the cigarette making machine, damage is reduced and product quality is maintained.

[0003] When the oil-free spider hand transports cigarette sticks, suction claws adapted to the size of the cigarette sticks are generally arranged at its end. To improve the transportation efficiency, multiple suction claws are generally arranged at the end of the oil-free spider hand to suck the cigarette sticks. However, when discharging the sucked cigarette sticks after transportation, the multiple sucked cigarette sticks will fall simultaneously, which is not convenient for adjusting the discharging and placing positions of the cigarette sticks, resulting in the need for secondary sorting and arranging later, which has a certain impact on the overall packaging and processing efficiency of the cigarette sticks.

[0004] In view of the above related technologies, the inventor believes that there is a defect that it is not convenient to simultaneously adjust the placement positions of multiple cigarette sticks when the oil-free spider hand adsorbs and transports cigarette sticks. Therefore, a transmission device for an oil-free spider hand of a cigarette making machine is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problem that it is not convenient to simultaneously adjust the placement positions of multiple cigarette sticks when the oil-free spider hand adsorbs and transports cigarette sticks, the present application provides a transmission device for an oil-free spider hand of a cigarette making machine.

[0006] The transmission device for an oil-free spider hand of a cigarette making machine provided by the present application adopts the following technical solutions:

[0007] A transmission device for an oil-free spider hand of a cigarette making machine includes a spider hand main body. A number of driving walls are movably installed on the outer surface of the spider hand main body. A connecting piece is rotatably installed at the bottom on one side of the multiple driving walls. A support frame is fixedly installed at the bottom end of the connecting piece. A grooved wheel is rotatably installed on one side of the inner wall of the support frame through a rotating shaft. A number of fixing grooves are formed on the outer surface of the grooved wheel. The rotating shaft at the bottom end of the grooved wheel extends below the support frame to be provided with a movable support plate. A number of suction claws are installed at the bottom edge of the movable support plate. An adsorption groove is formed in the middle of the bottom end of the suction claw. A rotating mechanism is further provided inside the support frame for adjusting the intermittent rotation of the movable support plate.

[0008] Preferably, the rotating mechanism includes a servo motor fixedly installed at the edge of the upper surface of the support frame. The output end of the lower bottom surface of the servo motor extends into the support frame and is equipped with a movable circular plate, and a limiting dial rod is welded to the bottom edge of the movable circular plate.

[0009] Preferably, the number of both the fixing grooves and the suction claws is five, and the multiple fixing grooves and suction claws are placed vertically aligned.

[0010] Preferably, the volume of the grooved pulley and the movable circular plate is smaller than the internal volume of the support frame, and both the grooved pulley and the movable circular plate are mutually fitted with the support frame.

[0011] Preferably, the outer diameter of the limiting dial rod is smaller than the distance between the two inner sides of the inner wall of the fixing groove. One side of the outer surface of the limiting dial rod is located inside the fixing groove, and the fixing groove and the limiting dial rod are mutually engaged.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By driving the connecting piece of the spider hand main body close to the cigarette, multiple suction claws adsorb the cigarette in the adsorption groove. When the cigarette is transferred and then put down from the suction claws, the movable circular plate rotates to drive the limiting dial rod to be limited in different positions of the fixing groove, driving the grooved pulley and the movable support plate to rotate intermittently as a whole, and adjusting the cigarettes in different positions to the discharging position; compared with the prior art, this solution has the effect of facilitating the adjustment of the overall discharging position of the suction claws, improving the neatness effect when the cigarettes are transferred and placed, solving the problem that the uneven placement of cigarettes affects subsequent processing steps, and improving the overall processing efficiency of the cigarettes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0020] This embodiment of the present application discloses an oil-free spider hand transmission device for a cigarette machine. Refer to Figures 1-4 , an oil-free spider hand transmission device for a cigarette machine, includes a spider hand main body 1. A number of drive walls 2 are movably installed on the outer surface of the spider hand main body 1. A connecting member 3 is rotatably installed at the bottom of one side of the multiple drive walls 2. A support frame 4 is fixedly installed at the bottom end of the connecting member 3. A grooved wheel 5 is rotatably installed on one side of the inner wall of the support frame 4 through a rotating shaft. A number of fixing grooves 6 are formed on the outer surface of the grooved wheel 5. The rotating shaft at the bottom end of the grooved wheel 5 extends below the support frame 4 to be provided with a movable support plate 7. A number of suction claws 8 are installed at the bottom edge of the movable support plate 7. The number of the fixing grooves 6 and the suction claws 8 is five each, and the multiple fixing grooves 6 and the suction claws 8 are placed vertically aligned. An adsorption groove 9 is formed in the middle of the bottom end of the suction claw 8. A rotating mechanism is further provided inside the support frame 4 for adjusting the intermittent rotation of the movable support plate 7.

[0021] The spider hand main body 1 drives the connecting member 3 to approach the cigarette, so that an external air extraction device extracts the air in the adsorption groove 9 to form a vacuum state, and further makes the suction claw 8 closely fit the surface of the cigarette. The suction claw 8 can firmly grasp the cigarette and release it when needed, enables the connecting member 3 to move to transport the adsorbed cigarette, and enables the suction claw 8 to rotate to adjust the placement position of the cigarette, thereby neatly arranging the transported cigarettes, reflecting the neat arrangement effect during cigarette transportation.

[0022] Refer to Figure 1 and Figure 4 , the rotating mechanism includes a servo motor 10. The servo motor 10 is fixedly installed at the edge of the upper surface of the support frame 4. The output end of the lower bottom surface of the servo motor 10 extends into the support frame 4 to be installed with a movable circular plate 11. A limit dial rod 12 is welded to the bottom edge of the movable circular plate 11. The volumes of the grooved wheel 5 and the movable circular plate 11 are smaller than the internal volume of the support frame 4. The grooved wheel 5 and the movable circular plate 11 are both fitted with the support frame 4. The outer diameter of the limit dial rod 12 is smaller than the distance between the two inner walls of the fixing groove 6. One side of the outer surface of the limit dial rod 12 is located inside the fixing groove 6, and the fixing groove 6 and the limit dial rod 12 are mutually engaged.

[0023] By starting the servo motor 10 to drive the movable circular plate 11 to rotate, the rotation of the movable circular plate 11 drives the limit dial rod 12 to be limited in different fixing grooves 6, so that the limit dial rod 12 drives the grooved wheel 5 to intermittently rotate at a certain angle, and further drives the movable support plate 7 to intermittently rotate synchronously with the grooved wheel 5, adjusting the suction claws 8 at different positions to the cigarette feeding position, reflecting the position adjustment effect after cigarette transportation.

[0024] The implementation principle of a transmission device for an oil-free spider hand of a cigarette making machine in an embodiment of the present application is as follows: The spider hand main body 1 drives the connecting piece 3 close to the cigarette, so that an external air extraction device extracts the air in the adsorption groove 9 to form a negative pressure, and then adsorbs the cigarette in the adsorption groove 9. The connecting piece 3 moves to transfer the adsorbed cigarette. When the cigarette is placed down from the suction claw 8 after being transferred, the servo motor 10 is started to drive the movable circular plate 11 to rotate. The input end of the power supply of the servo motor 10 is electrically connected to the output end of an external power supply, so that the rotation of the movable circular plate 11 drives the limit lever 12 to be limited in the fixed grooves 6 at different positions, and the limit lever 12 drives the sprocket 5 to intermittently rotate at a certain angle, and then drives the movable support plate 7 to synchronously and intermittently rotate with the sprocket 5, adjusts the suction claws 8 at different positions to the cigarette discharging position, and thus keeps the cigarettes neatly arranged; compared with the prior art, this solution has the effect of facilitating the adjustment of the overall discharging position of the suction claws 8, improves the neatness effect when the cigarettes are transferred and placed, solves the problem that the uneven placement of the cigarettes affects the subsequent processing steps, and improves the overall processing efficiency of the cigarettes.
