[0023] The working process of the utility model is as follows:
[0024] S1. When in use, the butt 1 is fixed, and the slider 15 can reciprocate under the control of the oil cylinder (other parts are not shown). The outer sleeve 12 is fixed on the slider 15, and the fixed block 10 is fixed to the outer sleeve 12. The screw cap 6 is pressed on the ratchet 5, and is pressed on the top of the outer sleeve 12 with appropriate force through the damping spring washer 7. Under the action of the damping friction force, the ratchet 5 needs to apply a certain force to rotate. The screw cap 6 and the ratchet 5 are connected to the screw 11 through a key bar, and the screw 11 and the feed shaft 13 are threadedly connected. The anti-rotation pin 19 controls the feed shaft 13 to prevent rotation. Rotating the screw cap 6 or the ratchet 5 counterclockwise can feed the diamond pen 14 through the screw 11 and the feed shaft 13;
[0025] S2, roller 2 and pawl 17 are fixed on swing plate 3, swing plate 3 can rotate, when swing plate 3 is between roller middle position 22 and roller 2 rear position, pawl 17 is pressed on ratchet 5 through pawl positioning spring 16, during the process from middle position to rear position, pawl 17 drives ratchet 5 to rotate, while during the process from rear position to middle position, ratchet 5 does not move under the action of damping friction force, pawl 17 returns, realizing unidirectional downward feeding of diamond pen 14. At roller front position 21, pawl 17 and ratchet 5 are always in disengagement state, and screw cap 6 can be rotated in reverse to realize up and down movement of diamond pen 14;
[0026] S3, the limit block 9 is positioned on the fixed block 10, and the limit block 9 has two positions to be moved, position one (such as Figure 3 ) releases the position restriction between the swing plate 3 and the fixed block 10. At this time, the swing plate 3 is in the front position 21 of the roller under the action of the tension spring 18 (such as Figure 3 As shown), it will not touch the bumper 1;
[0027] S4, the ratchet 5 and the pawl 17 are in the disengaged state, and the screw cap 6 can be rotated clockwise or counterclockwise to control the up and down movement of the diamond pen 14. The limit block 9 is pulled upward to block the swing plate 3, so that it can only swing between the roller middle position 22 and the roller rear position 23;
[0028] S5. During operation, if manual operation is required, the limit block 9 is moved to position 1, the swing plate 3 is kept in the front position 21 of the roller, and the upper and lower positions of the diamond pen 14 can be adjusted manually;
[0029] S6. If the feeding of the diamond pen 14 needs to be automatically controlled, the limit block 9 is pulled upward so that the swing plate 3 is in the middle position 22 of the roller. As the slider 15 drives it to the bumper 1, under the action of the bumper 1, the swing plate 3 rotates to the rear position 23 of the roller, and the pawl 17 drives the ratchet 5 to rotate, thereby indirectly driving the diamond pen 14 to feed;
[0030] S7. Structurally, the two pawls 17 are staggered with the ratchet teeth on the ratchet 5 by half a tooth. By adjusting the distance of the bumper 1, a stepped feed amount of 0.5, 1, 1.5, 2... teeth can be achieved. When the slider 15 retreats and leaves the bumper, under the action of the friction force of the damping spring pad 7, the ratchet 5 does not move, and the pawls 17, the swing plate 3, etc. retreat to the roller center position 22 under the action of the tension spring 18, waiting for the next cycle of feed, and the slider 15 reciprocates to achieve automatic feeding of the diamond pen 14.
[0031] Compared with the prior art, the present invention has the following beneficial effects:
[0032] The mechanically fed diamond pen feeding device can conveniently adjust the feeding modes of manual and automatic when in use, thereby reducing the operating intensity of the equipment, and has a simple structure and low production cost.
[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
