The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all belong to the protection scope of the present invention.

[0063] Such as Figures 1 to 7bAs shown, an automatic cutting device for glass capillaries provided according to the present invention solves problems such as low cutting efficiency, inconsistent cutting lengths, and uneven cut surfaces in previous devices. This device combines an automatic tube output structure, a capillary transport structure, and a tube cutting structure to achieve the effect of automatically and efficiently cutting glass capillaries, and the cut glass capillaries have consistent lengths and smooth and neat cut surfaces. Specifically, it includes an automatic feeding device, a material transport device, a cutting and tube-breaking device, a finished product box, and a sliding table device, where: the material transport device is arranged on the sliding table device; the automatic feeding device outputs the glass capillaries from the feeding port to the carrier table of the material transport device; the material transport device transports the glass capillaries through the cutting and tube-breaking device via the sliding table device and places the glass capillaries into the finished product box. The automatic feeding device includes a box body, a pushing device, a tube output pushing plate, a vibration device, and a sliding support, where: the tube output pushing plate is arranged at the bottom inside the box body and is pushed by the pushing device; a vibration device is arranged on the box body; the sliding support is arranged at the tube outlet of the box body. A baffle slot is arranged on the front surface of the box body, and a baffle is arranged in the baffle slot. The baffle is detachably connected to the front surface of the box body, and an outlet is formed between the bottom of the baffle and the box body. The pushing device includes a stepping motor and a pushing structure. The output end of the stepping motor is connected to the pushing structure, and the pushing structure is connected to the tube output pushing plate. The pushing structure includes a limiting plate arranged on the top of the stepping motor. A convex limiting slider is arranged on the top of the stepping motor, and the limiting plate reciprocates under the limitation of the convex limiting slider.

[0064] More specifically, the cutting and tube-breaking device includes a structural support, a pulley group, a cutting tool device, a tube-breaking device, and a waste collection device, where: the pulley group, the cutting tool device, the tube-breaking device, and the waste collection device are all arranged on the structural support; the cutting tool device and the tube-breaking device are arranged below the pulley group; the tube-breaking device is communicated with the waste collection device. The pulley group includes a pulley support and a plurality of pulleys arranged on the same mounting surface of the pulley support. The plurality of pulleys are arranged on the same straight line; the pulley support is connected to the structural support, and a first spring plunger is arranged on the structural support. The end surface of the first spring plunger contacts the upper surface of the pulley support. The cutting tool device includes an upper cutting tool and a lower cutting tool, which are respectively installed on an upper cutting tool support and a lower cutting tool support; the upper cutting tool support and the lower cutting tool support are vertically arranged on the structural support through linear slide rails; a second spring plunger, and the second spring plunger respectively contacts the upper surface of the upper cutting tool support and the lower surface of the lower cutting tool support; in the initial state, there is a gap between the upper cutting tool and the lower cutting tool, and the gap value is smaller than the diameter of the glass capillary. The tube-breaking device includes a tube-breaking baffle, and the upper end surface of the tube-breaking baffle is set as an inclined surface. A waste chute is arranged inside the structural support. The tube-breaking support is arranged at the feeding end of the waste chute, and the waste collection device is arranged at the discharging end of the waste chute.

[0065] The present invention utilizes the combination between a stepping motor driving structure and a vibration motor aluminum part structure. The capillary glass tubes are placed in the box body. Under the action of the vibration motor, the capillary glass tubes will neatly fall into the capillary glass tube push plate grooves one by one, and then the stepping motor driving mechanism will push the capillary glass tubes out of the box body one by one for production use. The present invention also has the function of automatically classifying capillary glass tubes. The specific operation method is to put capillary glass tubes of different lengths into the box body. The vibration motor vibrates and arranges the capillary glass tubes neatly, and then the stepping motor pushes the push plate to push the capillary glass tubes out of the box body. The capillary glass tubes slide down along the support and fall into the box. Therefore, the present invention can automatically discharge the tubes one by one, and the capillary glass tubes will not be damaged due to tube jamming during the tube discharging process. In addition, it has the characteristic of automatically classifying according to the different lengths of capillary glass tubes. The present invention provides an effective, convenient and fast method for the use and classification of capillary glass tubes, reducing the cumbersome steps of manual operation. It solves the cumbersome steps of manually classifying and arranging capillary glass tubes one by one, achieves the effect of automatically discharging the tubes one by one without tube jamming, and effectively improves the working efficiency of capillary glass tubes during use, cutting and classification.

[0066] Multiple pulleys of the present invention are arranged horizontally in a straight line, and the bottom of the pulley extends beyond the bottom surface of the pulley bracket. The pulley bracket is connected to the structure bracket. The connection here is not a fixed connection but a movable connection. When the pulley presses on the upper cover plate of the material transportation table, the mutual acting force between the two will generate an upward force on the pulley group. At this time, the spring plunger arranged on the structure bracket can play a buffering role. Similarly, when the glass capillary tube passes through the cutter device, the distance between the two cutters will increase with the increase of the outer diameter of the glass capillary tube under the elasticity of the spring plunger. When further passing through the tube bending device, since the tube bending stop piece of the tube bending device is arranged in an inclined plane, during the gradual movement of the glass capillary tube, the inclined plane and the glass capillary tube gradually approach, and the inclined plane gradually generates pressure on the glass capillary tube, causing the glass capillary tube to break. The remaining material after breaking enters the waste collection device. By the principle of the spring plunger, the present invention combines the cutter with the pulley group and the spring plunger. Two cutters are installed on the cutter bracket respectively, and a row of pulley groups are installed above the cutters. The function of the pulley group can not only reduce the friction with the glass capillary tube but also press the glass capillary tube to prevent it from shaking. Specifically, as Figure 5As described above, when the capillary is covered by the upper pressing plate on the material table, since there is no opposing force pressing on the capillary by the upper pressing plate, the capillary is still in a relaxed state at this time. When the material transport table passes through the pulley group, the pulley group will pass over the upper pressing plate of the material transport table. Under the action of the spring plunger of the pulley group, the pulley group tightly presses the upper pressing plate of the material, thereby achieving the effect of pressing the capillary. Because the spring plunger is elastic, when the glass capillary passes between the two cutting blades, the distance between the two cutting blades will increase with the increase of the outer diameter of the glass capillary under the elasticity of the spring plunger. This characteristic will not crush the glass capillary when it passes between the two cutting blades, and can also ensure that two cutting marks are made on the outer wall of the glass capillary while passing. As the glass capillary moves forward, when it passes through the breaking structure, the glass capillary is fixed under the action of the pulley group. When the two ends of the capillary move to the inclined groove of the tube-breaking bracket, a downward force will be generated on the two ends of the capillary due to the effect of the inclined groove. Under the action of the force, the glass capillary will break from the cutting marks. Because two scratches will be left on the glass capillary under the action of the two cutting blades, when breaking the tube, due to the effect of the scratches, the fracture surface will maintain a flat fracture opening.

[0067] The present invention can cut glass capillaries in batches, complete cutting and breaking at both ends at one time, and the cutting is flat and the cutting lengths are consistent. The cutting device can be adjusted according to the required length of the glass capillaries to cut glass capillaries with consistent cutting lengths. The tube-cutting mechanism has no power source device, saving energy. The present invention is applicable to the mechanism for cutting and breaking both ends of glass capillaries in batches. When cutting glass capillaries, it can not only cut in batches, but also ensure that the cutting lengths are the same and the cuts at both ends are flat, solving the cumbersome steps of traditional manual single-piece cutting and breaking of single capillaries, and achieving the effect of batch cutting, automatic breaking and consistent lengths.

[0068] Finally, the present invention transports the broken glass capillaries to the finished product box through the transport table. The electric sliding table plays a penetrating role. Through the electric sliding table, the glass capillaries are transported from single-piece discharging, to cutting, to breaking, to transporting to the finished product box, all of which are completed by the transport table using the electric sliding table.

[0069] The working process of the present invention is as follows: Glass capillary tubes of different lengths are placed into the automatic discharging structure. Through this structure, the glass capillary tubes will slide out one by one from the outlet and fall onto the carrier platform of the material conveying structure. When the number of capillary tubes placed reaches the program-set quantity, the stoppers on both sides of the carrier platform will place the capillary tubes in a suitable position for tube cutting. At this time, the pressing plate on the carrier platform drops down to press the whole row of glass capillary tubes to prevent shaking. Subsequently, the carrier platform moves under the drive of the electric linear slide to transport the glass capillary tubes to the tube cutting structure. After entering the tube cutting device, the glass capillary tubes will first pass through the cutting knife. Under the action of the cutting knife, two upper and lower scratches will be made on the outer wall of each passing glass capillary tube. As the slide continues to move forward, the glass capillary tubes with scratches are sent into the tube breaking structure, and the redundant glass capillary tubes at both ends are broken off from the scratches. The waste tubes broken off at both ends fall into the waste tube collection box, while the glass capillary tubes with smooth cuts continue to move with the carrier platform. When reaching the finished product collection box, the upper and lower pressing plates automatically lift up, and the cut glass capillary tubes are poured into the finished product collection box. Subsequently, the carrier platform returns to the initial position, waiting for the introduction of the next batch of glass capillary tubes to be cut. This cycle operates until all the glass capillary tubes are cut.

[0070] The advantages of the present invention are high automation, the ability to cut multiple glass capillary tubes quickly in batches, with smooth cuts and consistent cutting lengths. The tube cutting device can be adjusted according to requirements to cut glass capillary tubes of the required length. Through the mutual cooperation among the automatic tube discharging structure, the material conveying structure, and the tube cutting structure, the present invention realizes the function of quickly and automatically cutting multiple glass capillary tubes of different lengths in batches, with unified lengths and smooth and neat cuts. Among them, the material conveying structure integrates the main power for tube cutting, and the automatic tube cutting structure is a passive structure without a power source.

It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention.
