Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a copper strip processing and slitting machine with dust blowing and heat dissipation function. Background Technology

[0002] Copper strip is a flat or strip material made of copper. It has excellent electrical and thermal conductivity and is easy to process and shape. During processing, it is usually cut into copper strips of different widths by a slitting machine to meet different production needs.

[0003] However, when existing slitting machines process copper strips, copper shavings splash and adhere to the blade and strip surface, which not only affects the cutting accuracy and surface quality, but also increases the friction between the blade and the strip surface. Continuous friction causes the blade temperature to rise, accelerating wear and even deformation.

[0004] To address these issues, we propose a copper strip processing and slitting machine with dust blowing and heat dissipation functions. Utility Model Content

[0005] The purpose of this invention is to provide a copper strip processing and slitting machine with dust blowing and heat dissipation function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A copper strip processing slitting machine with dust blowing and heat dissipation function includes a base. Side frames are symmetrically installed at both ends of the base. A cutter shaft is rotatably installed between the two side frames via a mounting block one. Several blades are installed on the surface of the cutter shaft, and a motor that drives the cutter shaft to rotate is installed outside one of the mounting blocks one. A hanging rod is also installed between the side frames via a mounting block two. A hanging block is installed on the hanging rod above each blade, and a dust blowing nozzle and a hollow heat dissipation ring are installed below the hanging block. The air outlet of the dust blowing nozzle corresponds to the outer edge of the blade. The hollow heat dissipation rings are symmetrically distributed on both sides of the blade, and several air holes are opened on the side of the hollow heat dissipation rings near the blade. Each pair of hollow heat dissipation rings is connected by a connecting frame, and the connecting frame is connected to the dust blowing nozzle through an air distribution joint. Adjacent air distribution joints are connected by a connecting pipe, and an air supply pipe is also connected to the outside of the air distribution joint. A dust collection hopper is provided inside the base near the cutter shaft, and a negative pressure pipe is connected below the dust collection hopper.

[0008] In a further embodiment, a pair of guide rollers are rotatably mounted on the base, the pair of guide rollers being located on the front and rear sides of the dust collection hopper respectively.

[0009] In a further embodiment, the same adjusting rod runs through the interior of mounting block one and mounting block two within the same side frame, and the adjusting rod is threadedly connected to both mounting block one and mounting block two. The adjusting rod is rotatably connected to the side frame, and a worm gear is installed at one end of the adjusting rod that protrudes from the top of the side frame. The worm gear is externally engaged with a worm, and the two worms are coaxially connected by a connecting rod. A hand crank is also installed at the outer end of one of the worms.

[0010] In a further embodiment, a screw rod parallel to the lifting rod is also installed between the two mounting blocks. The lower half of the lifting block is slidably connected to the lifting rod, and a screw sleeve is rotatably installed in the upper half of the lifting block, and the screw sleeve is threadedly connected to the screw rod.

[0011] In a further embodiment, both ends of the screw and the lifting rod are fixed with mounting plates, and the mounting plates are locked to the mounting block two by multiple sets of bolts and nuts.

[0012] In a further embodiment, the hollow heat dissipation ring is composed of two symmetrical semi-rings. The outer shell of the semi-rings extends outward to form a connecting part. The connecting parts of the two semi-rings are stacked on top of each other and locked together by bolts and nuts. One end of the semi-ring is provided with a plug-in part, and the other end is provided with a plug-in groove. A sealing ring is fitted over the plug-in part. The plug-in part is inserted into the plug-in groove to press the sealing ring.

[0013] In a further embodiment, a bracket is also installed between the side frames, and the air supply pipe rests on the bracket.

[0014] In a further embodiment, the dust blowing nozzle adopts an inverted U-shaped structure, with both air outlets of the dust blowing nozzle tilted towards the blade and gradually narrowing to form a slit nozzle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a dust-blowing nozzle to blow dust off the outer edge of the blade's working surface, which helps reduce the adhesion of copper shavings. This not only improves cutting accuracy and surface quality but also reduces friction between the blade and the copper strip. At the same time, a hollow heat dissipation ring blows on the main surface of the blade, accelerating heat dissipation and effectively suppressing the temperature rise of the blade surface, reducing wear, and extending the blade's service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3A copper strip processing slitting machine with dust blowing and heat dissipation function includes a base 1. Vertical side frames 2 are symmetrically mounted at both ends of the base 1. A cutter shaft 3 is rotatably mounted between the two side frames 2 via mounting block 1 5. Several blades 4 are evenly mounted axially on the surface of the cutter shaft 3. A motor 6 for driving the cutter shaft 3 is mounted outside one of the mounting blocks 1 5. A hanging rod 8 is also mounted between the side frames 2 via mounting block 2 7, which is positioned above mounting block 1 5. A hanging block 9 is mounted above each blade 4 on the hanging rod 8, and a dust blowing nozzle 10 is mounted below the hanging block 9. The dust blowing nozzle 10... The air outlet corresponds to the outer edge of the blade 4. Specifically, the dust blowing nozzle 10 adopts an inverted U-shaped structure. Both air outlets of the dust blowing nozzle 10 are inclined towards the blade 4 and gradually narrow to form a slit nozzle 101, so as to generate a higher speed airflow to clean the working surface of the blade 4. The dust blowing nozzle 10 is symmetrically suspended by a pair of hollow heat dissipation rings 11 through the outer connecting frame. The pair of hollow heat dissipation rings 11 are symmetrically distributed on both sides of the blade 4 and are both sleeved around the blade shaft 3. Several air holes are opened on the side of the hollow heat dissipation rings 11 near the blade 4, so as to blow on the main surface of the blade 4 and accelerate heat dissipation.

[0026] Please see Figure 1-2 To facilitate air supply to the hollow heat dissipation rings 11 and the dust blowing nozzles 10, each pair of hollow heat dissipation rings 11 is connected by a connecting frame 12, and the connecting frame 12 is connected to the dust blowing nozzles 10 by an air distribution connector 13. Adjacent air distribution connectors 13 are connected by a connecting pipe 14. An air supply pipe 15 is also connected to the outside of the air distribution connector 13. The air supply pipe 15 is connected to an external air source supply device (not shown in the figure). Specifically, a bracket 27 is also installed between the side frames 2, and the air supply pipe 15 rests on the bracket 27, which helps to prevent the air supply pipe 15 from falling and contacting the copper strip.

[0027] Please see Figure 1-2 Considering that copper shavings are easily scattered after dust blowing, a downward-recessed dust collection hopper 16 is provided in the base 1 near the cutter shaft 3 for collection. A negative pressure pipe 17 is connected to the bottom of the dust collection hopper 16, and a negative pressure device (not shown in the figure) is connected to the outside of the negative pressure pipe 17. This allows the dust collection hopper 16 to attract and collect the scattered copper shavings under negative pressure. Specifically, for the convenience of copper strip transmission, a pair of guide rollers 18 are also rotatably installed on the base 1. The pair of guide rollers 18 are located on the front and rear sides of the dust collection hopper 16, and the copper strip is supported by the guide rollers 18.

[0028] Please see Figure 1-2Considering that different thicknesses of copper strips may be processed during actual processing, the height of the cutter shaft 3 needs to be adjustable. The same adjusting rod 19 runs vertically through the mounting blocks 5 and 7 inside the same side frame 2, and the adjusting rod 19 is threaded to both mounting blocks 5 and 7. The adjusting rod 19 is rotatably connected to the side frame 2, so that when the adjusting rod 19 is rotated, the thread action can synchronously drive the mounting blocks 5 and 7 to move, ensuring that the relative position of the cutter shaft 3, the hollow heat dissipation ring 11, and the dust blowing nozzle 10 does not change. Furthermore, a worm gear 20 is coaxially mounted on one end of the adjusting rod 19 that protrudes from the top of the side frame 2. The worm gear 20 is externally meshed with a worm 21. The worm 21 is rotatably supported on the side frame 2 through a bearing seat, and the two worms 21 are coaxially connected through a connecting rod 22. The outer end of one of the worms 21 protrudes from the bearing seat and is mounted with a hand crank 23 for easy passage through the hand crank 23.

[0029] Please see Figure 3 Considering that in actual processing, there may be situations where the spacing of the blades 4 needs to be adjusted to cut copper strips of different widths, a screw 24 parallel to the hanger 8 is installed between the mounting blocks 2 7. The screw 24 is located directly above the hanger 8. The lower half of the hanging block 9 is penetrated by the hanger 8, and the two are slidably connected. A threaded sleeve 25 is rotatably installed in the upper half of the hanging block 9. Specifically, the threaded sleeve 25 extends partially out of the side wall of the hanging block 9, and the threaded sleeve 25 is threadedly connected to the screw 24. This allows the hanging block 9 to be moved axially along the screw 24 and the hanger 8 by the thread action when the threaded sleeve 25 is turned to adjust its position, which is used to adapt to the position adjustment of the blades 4.

[0030] Please see Figure 1-2 To facilitate the disassembly and assembly of the dust blowing and heat dissipation mechanisms, mounting plates 26 are fixed at both ends of the screw 24 and the hanger 8. The mounting plates 26 are locked to the mounting block 7 by multiple sets of bolts and nuts, allowing them to be disassembled as a whole.

[0031] Please see Figure 3-4 The hollow heat dissipation ring 11 is composed of two symmetrical semi-rings 111. The upper semi-rings 111 of each pair of hollow heat dissipation rings 11 are connected by a connecting frame 12. The outer shell of the semi-rings 111 extends outward radially to form a connecting part 112. The connecting parts 112 of the two semi-rings 111 are stacked and locked together by bolts and nuts, so that it can be fitted over the cutter shaft 3. One end of the semi-ring 111 is provided with a protruding frustum-shaped insertion part 113, and the other end is provided with an insertion groove. A sealing ring 114 is fitted over the insertion part 113. When the two semi-rings 111 are spliced, the insertion part 113 is inserted into the insertion groove and presses the sealing ring 114 to achieve a sealed connection.

[0032] Working principle: During use, the copper strip is first fed by the unwinding roller (not shown in the figure) and then passes under the cutter shaft 3, where it is placed on a pair of guide rollers 18. Finally, it is taken in by the take-up roller (not shown in the figure). At this time, the copper strip is taut under the cutter shaft 3. The cutter shaft 3 drives the blade 4 to rotate, cutting the copper strip. At the same time, the air supply equipment supplies air to the hollow heat dissipation ring 11 and the dust blowing nozzle 10 to dissipate heat and clean the blade 4. The negative pressure equipment collects the blown copper shavings through the dust collection hopper 16.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
