The stepping motor 17 provides power for the spindle 4 to rotate, and the outer edge of the driving wheel is provided with a driving wheel silica gel pad 5. The two capillary guide plates 7 arranged between the spindle bearing blocks 2 on the two sides control the basic trend of the capillary to be cut through the holes on the capillary guide plates.
The upper and lower parts of the capillary tube are respectively extruded by a driving wheel and a driven wheel 9 to form an upper roller and a lower roller which drive the capillary tube to be delivered forwards, wherein in order to prevent the capillary tube from being damaged by clamping, a driving wheel silica gel pad 5 is arranged on the surface of the driving wheel.
Further, as shown in fig. 4, the spindle base 1, the spindle bearing seat 2, the deep groove ball bearing 3, the spindle 4, the driving wheel silica gel pad 5 and the bearing cover 6 form a member capable of stably rotating with low resistance, and the driving wheel silica gel pad 5 is arranged at the maximum diameter part of the spindle and is matched with the driven wheel 9 to form an upper roller and a lower roller. The main shaft 4 is connected with a stepping motor 17 through a coupler 15, and the stepping motor 17 is arranged on a motor base 16. The capillary guide plate 7 is arranged on two sides of the joint radial direction of the main shaft 4 and the driven wheel 9, the capillary guide plate 7 is provided with a tiny chamfer hole for the capillary to pass through, and the center line of the hole is aligned with the joint surface of the main shaft 4 and the driven wheel 9.
As shown in fig. 3, the driven wheel limiting block 13 and the driven wheel seat 14 form a sliding table member, the driven wheel support 8 and the driven wheel sliding block 11 are respectively arranged at the bottom and the top of the driven wheel sliding rod 10, the driven wheel sliding rod 10 needs to pass through the driven wheel limiting block 13 to form a member capable of sliding relative to the sliding table, the driven wheel 9 is arranged on the driven wheel support 8, the spring 12 is arranged on the driven wheel sliding rod 10, the top is limited at the driven wheel limiting block 13, the bottom is limited at the driven wheel support 8, and the driven wheel always has downward pretightening force. The driven wheel is made of a rubber material with relatively high friction. The driven wheel sliding rod 10, the driven wheel sliding block 11 and the driven wheel limiting block 13 need to have enough guidance, so that the driven wheel can swing in a smaller range.
The cutting part is composed of main components such as a cutter main bracket 18, a silica gel pad 19, an upper cover seat 20, a capillary guide block 21, an upper cover 22, an upper cover pressing block 23, a connecting block 24, a motor 25, a motor bracket 26, a motor seat 27, a motor 28, a slide rail bracket 29, a slide rail seat 30, a slide bearing cover 31, a lower tool rest 32, a slide bearing 33, a slide pin 34, an upper tool rest 35, a blade 36, a collecting box 37, a blanking frame 38 and the like.
As shown in fig. 5, the slide rail support 29, the slide rail seat 30, and the slide pin 34 form a slide rail seat member, the slide bearing cover 31, the lower blade holder 32, the slide bearing 33, and the upper blade holder 35 form a slide mechanism, the blade 36 is mounted on the upper blade holder 35, the lower blade holder 32 is connected to the motor 28, and the motor 28 can move left and right (i.e., move in the cutting direction of the blade 36). The slide pin 34 essentially forms a slide bar that slides the corresponding assembly.
The upper cover member shown in fig. 6 has a function of pressing and fixing the capillary when cutting the capillary and breaking the capillary after the cutting operation is completed. The upper cover seat 20 and the upper cover 22 form a rocker pair, the upper cover 22 is connected with a motor 25 through a connecting block 24, and the motor can move up and down to drive the upper cover 22 to rotate with the upper cover seat 20. The upper cover pressing block 23 is installed in the upper cover 22, can slide up and down, and has a certain downward pretightening force to act on the capillary tube.
As shown in fig. 7, the upper cover member, the holder member, the capillary guide block 21, the silica gel pad 19, and the blanking frame 38 of fig. 6 are mounted on the cutter head holder 18, and the motor 25 moves downward until the upper cover base 20 contacts the silica gel pad 19, and the motor 28 moves rightward until the blade 36 passes through the upper cover pressing block 23. The silica gel pad 19 is used for placing the capillary to be cut, and is not suitable for using hard materials as cushion blocks because the capillary is a quartz capillary, and the silica gel pad and other materials have the advantages of tight compaction, high friction, no crushing of the capillary, support of certain deformation and the like. Moreover, the silica gel pad is selected for the following reasons:
1. the capillary is quartz, and if a material with high hardness is used, the capillary is crushed;
2. when cutting the capillary, the capillary is pressed at the cutting point and is not deformed, so that the capillary is pulled at the cutting point due to the tensile force at the two ends and the upward blade jacking force, and the capillary section is provided with large burrs;
3. if the gasket is made of hard materials, the capillary tube is likely to move left and right when being cut by the blade, the silica gel pad is deformed, a groove in the shape of the capillary tube can be formed when the capillary tube is pressed, and the capillary tube is limited to move left and right greatly.
The automatic fixed-length cutting device for the capillary provided by the invention comprises the following working steps:
the capillary to be cut is pressed by the spindle 4 and the follower 9 through the guide hole provided in the capillary guide plate 7, and then fed to the capillary cutting station through the guide hole of the capillary guide plate 7 on the other side. The main shaft 4 and the driven wheel 9 are sleeved with a driving wheel silica gel pad 5, the driven wheel 9 can have pre-tightening pressure with the main shaft 4 through a mechanism (namely a driven wheel component shown in fig. 3) which consists of a driven wheel sliding rod 10, a driven wheel sliding block 11, a spring 12, a driven wheel limiting block 13 and a driven wheel seat 14 and is movable up and down, the stepping motor 17 rotates and drives the main shaft 4 to rotate through a coupler 15, the main shaft 4 rotates and drives the capillary tube to push forwards, and the pushing distance is determined with the rotation angle of the stepping motor 17.
The slide rail bracket 29, the slide rail seat 30, the slide bearing cover 31, the lower tool rest 32, the slide bearing 33, the slide pin 34, the upper tool rest 35 and the blade 36 form a tool rest which can be moved left and right by the motor 28.
The upper cover seat 20, the capillary guide block 21, the upper cover 22, the upper cover pressing block 23, the connecting block 24 and the motor 25 form an upper cover mechanism which can be driven by the motor 25 to complete up-and-down opening and closing, wherein the upper cover pressing block 23 can move up and down, and the upper cover 22 is linked with the upper cover seat 20 through a pin. The motor 25 is at the upper limit position, the capillary tube passes through the tiny gap between two adjacent capillary guide blocks 21 after being led out by the capillary guide plate 7 of the wire feeding part and is clamped by the two capillary guide blocks so as to limit the capillary tube to move left and right and be led to the tool rest part, the motor 25 is electrified to move downwards, the upper cover moves downwards to press the capillary tube, the motor 28 is electrified to push the tool rest to scratch the capillary tube, so that a scratch is generated on the surface of the capillary tube, when the tool rest moves to the limit position, the position of the upper cover pressing block 23 deviates from the capillary tube scratch position, and therefore the capillary tube can slide up and down in a certain range, wherein the upper cover pressing block 23 is not contacted with the tool rest any more when the tool rest moves to the limit position, and moves downwards under the action of dead weight, and the capillary tube scratch position is pressed and broken (the upper cover pressing block 23 is always contacted with the capillary tube) due to the stress concentration effect. The upper cover pressing block 23 moves downwards under the action of dead weight, the capillary with scratches is broken, the motor 25 loses electricity, moves upwards, drives the upper cover mechanism to rotate upwards, the broken capillary falls downwards, slides downwards to the collecting box 37 on the blanking frame 38 through the dead weight, the motor 28 loses electricity, and the cutter frame is pulled to return to the original position under the action of the spring 39 (see figure 5). Of course, instead of using a combination of a motor and a spring to increase the restoring force, an electromagnet may be used to meet the performance requirements.
After a cutting cycle is finished, the stepping motor 17 rotates, the capillary is fed, the stepping motor 17 stops after the specified length is fed, the motor 25 is powered on, the capillary is pressed, the motor 28 is powered on, the tool rest is pushed, the upper cover pressing block 23 slides downwards, the capillary is broken by pressing, the motor 25 is powered off and moves upwards, and the motor 28 is powered off and returns to the original position.

1. the driving driven wheel provided with the silica gel surface is driven by a stepping motor, and the fine capillary is accurately fed through a capillary guide hole;
2. the working procedure that the cutting knife can automatically slide and cut is completed by utilizing the linear motor and the sliding rail mechanism;
