Description

Technical Field

[0001] This invention relates to the field of straightening and cutting equipment technology, specifically to a straightening and cutting machine for processing aluminum rods of aquarium cleaning brushes. Background Technology

[0002] When keeping fish, the aquarium glass needs to be cleaned regularly, which requires a cleaning brush. Typical aquarium cleaning brushes use an aluminum rod with an extended handle to easily scrub the deeper interior walls of the aquarium. The handles of conventional aquarium cleaning brushes are mostly made of aluminum rod-shaped material, and because the aluminum rods are relatively long, they are prone to bending and deformation during processing. Therefore, a straightening and cutting machine is needed to straighten and cut the aluminum rods used to make the aquarium cleaning brush handles.

[0003] According to Chinese patent announcement number CN221065218U, this patent discloses a straightening and cutting machine. This utility model utilizes a multi-station method with rapid switching, which can improve cutting efficiency. At the same time, it can be combined with a fixed length mechanism to quickly position the bar, thereby improving cutting accuracy and processing efficiency.

[0004] The above technical solution uses multiple straightening components with fixed angles to straighten the rod by squeezing it in different directions. Such straightening can only correct overall or local bending. However, when the material has local bulges, depressions or twisting deformations, it is difficult to achieve fine-tuning and shaping of the aluminum rod by using this fixed-angle straightening method. Summary of the Invention

[0005] The purpose of this invention is to provide a straightening and cutting machine for processing the aluminum rod of a fish tank cleaning brush, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a straightening and cutting machine for processing aluminum rods of aquarium cleaning brushes, comprising a frame, wherein a traction assembly for pulling aluminum rods is provided on the top of the frame;

[0007] One side of the traction assembly is provided with a longitudinal straightening assembly, a transverse straightening assembly and a reversing straightening assembly in sequence, and the other side of the traction assembly is provided with a cutting mechanism for longitudinally cutting the aluminum rod. The cutting mechanism for longitudinally cutting the aluminum rod includes a protective mechanism to prevent the aluminum rod from flying upwards at the moment of cutting.

[0008] The reversing and straightening assembly includes a fixed beam mounted on a frame, a movable beam on one side of the fixed beam, a fixed straightening wheel connected to the upper side of the fixed beam, and a movable straightening wheel connected inside the movable beam via a sliding member.

[0009] The fixed beam is fixed with disc-shaped rails at equal intervals corresponding to the positions of the movable straightening wheels, and two turntables are fitted on the disc-shaped rails and fastened with screws. The movable beam drives the movable straightening wheels to lift one side of the aluminum rod and the turntables to press the other side of the aluminum rod, so that the reversing straightening assembly can straighten the moving aluminum rod on both sides of the circumference.

[0010] Preferably, a geared motor for driving the traction assembly is installed on the rear side of the frame near the traction assembly.

[0011] The traction assembly for pulling the aluminum rod includes a limiting frame mounted on the upper surface of the frame. Inside the limiting frame is a driving wheel connected to the output end of a geared motor via a coupling, and a pressing wheel that slides above the driving wheel by a compression spring. The aluminum rod passes between the driving wheel and the pressing wheel and is rolled and pulled by both of them.

[0012] A toothed ring is fixed to the surface of the driving wheel, and a toothed roller that meshes with the toothed ring is movably connected to the lower part of the limiting frame near the driving wheel. A lever is fixed to one side of the toothed roller.

[0013] Preferably, the fixed beam is fixed with arc-shaped rails at both ends, and the movable beam is equipped with gears that slide and engage with the arc-shaped rails at both ends, with the axis of the arc-shaped rails and the axis of the gears being coaxial.

[0014] The outer walls of both the fixed straightening wheel and the movable straightening wheel are provided with grooves, and a through hole is provided at the center of the gear disc. The aluminum rod passing through the groove on the outer wall of the fixed straightening wheel is collinear with the axis of the through hole at the center of the gear disc.

[0015] Preferably, the sliding member includes a slider that slides inside the movable beam, a movable straightening wheel is connected to the upper side of the slider, a tension spring is connected between the slider and the movable beam, and an adjusting bolt for pushing the slider to move is threaded to the side of the movable beam.

[0016] Preferably, a drive shaft is connected to the bottom of the fixed beam via a bearing, and two transmission gears that mesh with a gear disk are provided on the drive shaft, with a drive gear abutting at the end of the drive shaft;

[0017] The outer surface of the gear disc is integrally formed with a disc. An anti-loosening plate that is movably connected to the drive shaft is provided on the outer side of the gear disc away from the movable beam, and an auxiliary wheel that abuts against the inner wall of the disc is connected to the anti-loosening plate.

[0018] Preferably, the outer edge of the turntable is provided with a groove, and an arc-shaped pressure block is embedded in the groove, with an elastically deformable gap between the groove and the two sides of the pressure block.

[0019] A push-pull arm is provided between two adjacent turntables. One end of the push-pull arm is connected to a crossbar that passes through a pre-drilled hole on the surface of the turntable. A support seat that docks with the push-pull arm is fixed on the upper side of the movable beam located between two adjacent movable straightening wheels.

[0020] Preferably, a drive mechanism is provided on the side of the frame near the traction component. The drive mechanism includes a slide mounted on the upper surface of the frame. An L-shaped slide plate is longitudinally slidably connected to one side of the slide plate. The surface of the L-shaped slide plate is provided with a horizontal strip hole that mates with the lever. A rack that meshes with the drive gear is provided on the inner corner side of the L-shaped slide plate.

[0021] Preferably, the cutting mechanism for longitudinally cutting aluminum rods includes a mounting base mated to the upper side of a frame, a hydraulic cylinder mounted at the bottom of the frame, a cutting blade fastened to the output end of the hydraulic cylinder, and a guide seat bolted to the top of the mounting base, with an inner cavity in the middle of the guide seat for the aluminum rod to pass through laterally.

[0022] Preferably, the protective mechanism includes a limiting pin threaded to one side of the guide seat, a sliding sleeve that is engaged with the limiting pin on the outer side of the guide seat, an anti-loosening spring for pushing the sliding sleeve on the limiting pin, and a roller for pressing down on the aluminum rod movably connected to the inner side of the sliding sleeve.

[0023] Preferably, the longitudinal straightening assembly and the transverse straightening assembly are respectively provided with staggered vertical straightening wheels and staggered transverse straightening wheels. The aluminum rod passing through the longitudinal straightening assembly and the transverse straightening assembly will be radially straightened and compressed by the vertical straightening wheels and the transverse straightening wheels in a perpendicular manner.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The straightening and cutting machine for processing the aluminum rod of the aquarium cleaning brush straightens the aluminum rod that is bent in whole or in part through the longitudinal straightening component and the transverse straightening component. The driving mechanism causes the movable beam of the reversible straightening component to reciprocate on one side of the fixed beam, thereby driving the rotating turntable to continuously straighten the outer periphery of the aluminum rod by sliding compression. Then, the movable beam drives the movable straightening wheel to reciprocate to lift the aluminum rod away from the turntable, ensuring that the reversible straightening component straightens the two circumferential surfaces of the aluminum rod for making the aquarium cleaning brush handle, so that the twisted aluminum rod can be reciprocated and finely shaped.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-5 and Figure 7 The present invention provides a technical solution: a straightening and cutting machine for processing aluminum rods of aquarium cleaning brushes, including a frame 1, a traction component 2 for pulling aluminum rods is provided on the top of the frame 1, a longitudinal straightening component 4, a transverse straightening component 5 and a reversing straightening component 6 are arranged sequentially on one side of the traction component 2, a cutting mechanism 8 for longitudinally cutting aluminum rods is provided on the other side of the traction component 2, and a reduction motor 3 for driving the traction component 2 to operate is installed on the rear side of the frame 1 near the traction component 2;

[0040] The traction assembly 2 for pulling the aluminum rod includes a limiting frame mounted on the upper surface of the frame 1. Inside the limiting frame is a driving wheel 201 connected to the output end of the geared motor 3 via a coupling, and a pressing wheel 202 that slides above the driving wheel 201 by a compression spring. The aluminum rod passes between the driving wheel 201 and the pressing wheel 202 and is rolled and pulled by both. A toothed ring 203 is fixed on the surface of the driving wheel 201. A toothed roller 204 that meshes with the toothed ring 203 is movably connected to the lower part of the limiting frame near the driving wheel 201. A lever 205 is fixed on one side of the toothed roller 204.

[0041] In this embodiment, the geared motor 3 is started to drive the coupling and the drag wheel 201 to rotate. The compression spring presses the extrusion wheel 202 downward, so that the cooperation between the drag wheel 201 and the extrusion wheel 202 can pull the aluminum rod, ensuring that the aluminum rod can pass through the areas of the longitudinal straightening component 4, the transverse straightening component 5 and the direction-changing straightening component 6 when it is pulled and completes the straightening and shaping. At the same time, the aluminum rod can be longitudinally cut when it passes through the cutting mechanism 8.

[0042] Please see Figure 1 The longitudinal straightening component 4 and the transverse straightening component 5 are respectively provided with staggered vertical straightening wheels and staggered transverse straightening wheels. The aluminum rod passing through the longitudinal straightening component 4 and the transverse straightening component 5 will be radially straightened and squeezed by the vertical straightening wheels and the transverse straightening wheels.

[0043] In this embodiment, when the aluminum rod for making the aquarium cleaning brush handle passes through the middle of the longitudinal straightening component 4 and the transverse straightening component 5 in sequence, the staggered vertical straightening wheels and transverse straightening wheels can press the outer wall of the aluminum rod from mutually perpendicular directions, ensuring that the aluminum rod that is bent overall or partially bent can be initially straightened by a large margin during processing.

[0044] Please see Figures 2-6 , Figure 11 and Figure 12 The reversing and straightening assembly 6 includes a fixed beam 601 mounted on the frame 1, a movable beam 602 on one side of the fixed beam 601, a fixed straightening wheel 6011 connected to the upper side of the fixed beam 601, a movable straightening wheel 6021 connected inside the movable beam 602 via a sliding member, an arc-shaped rail 603 fixed at both ends of the fixed beam 601, and a gear 604 slidably connected to the arc-shaped rail 603 mounted at both ends of the movable beam 602, with the axis of the arc-shaped rail 603 and the axis of the gear 604 being coaxially aligned.

[0045] The outer walls of both the fixed straightening wheel 6011 and the movable straightening wheel 6021 are provided with grooves. A through hole is provided at the center of the gear disk 604. The aluminum rod passing through the groove on the outer wall of the fixed straightening wheel 6011 is collinear with the axis of the through hole at the center of the gear disk 604.

[0046] In this embodiment, the toothed discs 604 at both ends of the movable beam 602 are slidably connected to the arc-shaped rails 603 at both ends of the fixed beam 601. The aluminum rod is clamped by the fixed straightening wheel 6011 on the upper side of the fixed beam 601 and the movable straightening wheel 6021 on the movable beam 602, so that the movable straightening wheel 6021 can get close to the fixed straightening wheel 6011 to clamp and squeeze the aluminum rod.

[0047] Please see Figures 4-6 The sliding component includes a slider that slides inside the movable beam 602, a movable straightening wheel 6021 connected to the upper side of the slider, a tension spring connected between the slider and the movable beam 602, and an adjusting bolt for pushing the slider to move is threaded to the side of the movable beam 602.

[0048] In this embodiment, the rotating adjusting bolt is threadedly connected to the side of the movable beam 602. When the rotating adjusting bolt squeezes the slider and stretches the tension spring, the slider will drive the movable straightening wheel 6021 to the position of the fixed straightening wheel 6011 on the fixed beam 601, ensuring that the gap between the movable straightening wheel 6021 and the fixed straightening wheel 6011 can be manually adjusted and controlled.

[0049] Please see Figure 2 , Figures 4-7 , Figure 11 and Figure 12A drive shaft 605 is connected to the bottom of the fixed beam 601 via a bearing. Two transmission gears 6052 that mesh with the gear disk 604 are provided on the drive shaft 605. The drive gears 6051 are connected to the end of the drive shaft 605.

[0050] The outer surface of the gear disc 604 is integrally formed with a disc. The outer side of the gear disc 604 away from the movable beam 602 is provided with an anti-loosening plate 606 that is movably connected to the drive shaft 605, and an auxiliary wheel that abuts against the inner wall of the disc is connected to the anti-loosening plate 606.

[0051] In this embodiment, the drive shaft 605 can drive the transmission gear 6052 to mesh with the gear disk 604, thereby enabling the movable beam 602 to deflect along the arc track 603 by the two gear disks 604.

[0052] Because an auxiliary wheel that abuts against the inner wall of the disc is provided on the anti-loosening plate 606, when the bottom end of the anti-loosening plate 606 is movably connected to the drive shaft 605 through the bearing, the anti-loosening plate 606 will limit the inner wall of the disc through the auxiliary wheel, so that the gear disc 604 continuously meshes with the transmission gear 6052, preventing the gear disc 604 from meshing and disengaging with the transmission gear 6052.

[0053] Please see Figures 2-6 and Figures 10-12 The fixed beam 601 is fixed with disc rails 607 at equal intervals, corresponding to the positions of the movable straightening wheel 6021. Two turntables 608 are fitted onto the disc rails 607 and fastened with screws. The two turntables 608, which are fastened to the disc rails 607 with screws, can be quickly installed and removed. The outer edge of the turntable 608 is provided with a groove, and an arc-shaped pressure block 6081 is embedded in the groove. There is a gap for elastic deformation between the groove and the two sides of the pressure block 6081.

[0054] A push-pull arm 609 is provided between two adjacent turntables 608. One end of the push-pull arm 609 is connected to a crossbar 6092 that passes through a pre-drilled hole on the surface of the turntable 608. A support seat 6091 that is connected to the push-pull arm 609 is fixed on the upper side of the movable beam 602 located between two adjacent movable straightening wheels 6021.

[0055] In this embodiment, the upwardly deflected movable beam 602 pushes the push-pull arm 609 through the support seat 6091, thereby the push-pull arm 609 drives the crossbar 6092 to press the turntable 608 to rotate forward around the disc rail 607. The forwardly rotating turntable 608 will cause the pressure block 6081 on the outer edge to deflect at an angle. Then, the pressure block 6081 with the deflection angle will slide and press the aluminum rod between the fixed straightening wheel 6011 and the movable straightening wheel 6021 from bottom to top. At this time, when the pressure block 6081 with the deflection angle presses the aluminum rod on one side of the movable straightening wheel 6021 to achieve sliding correction, the pressure block 6081, which can undergo elastic deformation, will retract into the elastic deformation gap left between the groove and the pressure block 6081 when it is pressed.

[0056] Conversely, the downward-deflecting movable beam 602 will drive the crossbar 6092 through the push-pull arm 609 to pull the turntable 608 to rotate in the opposite direction around the disc rail 607. The reverse-rotating turntable 608 will drive the pressure block 6081 on the outer edge to slide and squeeze the aluminum rod between the fixed straightening wheel 6011 and the movable straightening wheel 6021 from top to bottom.

[0057] In summary, the movable beam 602 drives the turntable 608 to rotate in both directions, causing the pressure block 6081 to reciprocate in both directions. Thus, the pressure block 6081, which is in contact with the movable straightening wheel 6021, can continuously achieve sliding compression straightening of the outer periphery of the aluminum rod, and can reciprocate to compress the protrusions and depressions on the surface of the aluminum rod.

[0058] The movable beam 602 drives the movable straightening wheel 6021 to reciprocate to lift one side of the aluminum rod, and the turntable 608 reciprocates to squeeze the other side of the aluminum rod, so that the reversing straightening component 6 can straighten the moving aluminum rod on both sides of the circumference.

[0059] To fully correct the raised and recessed surfaces of the aluminum rod used to make the aquarium cleaning brush handle, the following features are also provided:

[0060] Please see Figures 2-6 The side thickness of the equally spaced pressure blocks 6081 along the direction of movement of the aluminum rod is set to be equal.

[0061] In this embodiment, when the moving aluminum rod repeatedly slides and presses against multiple pressure blocks 6081 of the same thickness, the multiple pressure blocks 6081 of the same thickness can repeatedly correct the outer side of the aluminum rod, ensuring that the protrusions and depressions on the surface of the aluminum rod can be fully corrected.

[0062] To facilitate rapid correction of the torsional deformation of the aluminum rod surface used to manufacture the aquarium cleaning brush handle, the following features are also included:

[0063] Please see Figures 2-6The side thickness of the equally spaced pressure blocks 6081 along the moving direction of the aluminum rod is set to decrease progressively.

[0064] In this embodiment, when the moving aluminum rod is repeatedly pressed against multiple pressure blocks 6081 with decreasing thickness, the multiple pressure blocks 6081 with decreasing thickness can gradually straighten the outer side of the aluminum rod, so that the aluminum rod is first pressed with a large force and then the pressing force is gradually reduced to achieve pressing and straightening with gradually decreasing force, ensuring that the torsional deformation of the aluminum rod surface can be quickly straightened.

[0065] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 A drive mechanism 7 is provided on the side of the frame 1 near the traction component 2. The drive mechanism 7 includes a slide 701 mounted on the upper surface of the frame 1. An L-shaped slide plate 702 is longitudinally slidably connected to one side of the slide 701. A horizontal strip hole is opened on the surface of the L-shaped slide plate 702 to engage with the lever 205. A rack that meshes with the drive gear 6051 is provided on the inner corner side of the L-shaped slide plate 702.

[0066] In this embodiment, the slide block 701 mounted on the upper surface of the frame 1 can guide the longitudinally moving slide plate 702. When the L-shaped slide plate 702 slides up and down along the slide block 701, the rack on the slide plate 702 will mesh with the drive gear 6051 for transmission. When the rotating toothed roller 204 drives the lever 205 to deflect upward, the lever 205 will press the slide plate 702 upward along the horizontal strip hole on the surface of the slide plate 702. Thus, the upward-moving slide plate 702 will drive the drive gear 6051 to rotate forward. Conversely, the downward-deflecting lever 205 will drive the slide plate 702 to move downward, and the downward-moving slide plate 702 will drive the drive gear 6051 to rotate in reverse.

[0067] It should be noted that when the drive gear 6051 drives the drive shaft 605 to rotate forward, the drive shaft 605 will mesh with the gear disk 604 through the transmission gear 6052, causing the gear disk 604 to drive the movable beam 602 to deflect upward. As a result, the movable beam 602 will drive the movable straightening wheel 6021 to deflect upward and lift and straighten the surface of the aluminum rod away from the turntable 608 in an upward sliding state. Since the upward deflection of the movable beam 602 can drive the pressure block 6081 to squeeze and straighten the aluminum rod side close to the turntable 608 in an upward sliding state.

[0068] When the drive gear 6051 drives the drive shaft 605 to reverse, the movable beam 602 will drive the movable straightening wheel 6021 to deflect downward and lift and straighten the surface of the aluminum rod away from the turntable 608 in a sliding state. Since the downward deflected movable beam 602 can drive the pressure block 6081 to squeeze and straighten the aluminum rod near the turntable 608 in a sliding state.

[0069] Therefore, by using the reciprocating rotating movable beam 602 to drive the movable straightening wheel 6021 to reciprocately lift one side of the aluminum rod, and then using the reciprocating rotating turntable 608 to drive the pressure block 6081 to reciprocately press the other side of the aluminum rod, it can be ensured that the reversing straightening component 6 performs reversing straightening on both sides of the moving aluminum rod, and ensure that the aluminum rod that has undergone twisting deformation can be reciprocated and finely adjusted and shaped.

[0070] Please see Figure 1 , Figure 8 and Figure 9 The cutting mechanism 8 for longitudinally cutting aluminum rods includes a mounting base 801 docked to the upper side of the frame 1, a hydraulic cylinder 802 mounted at the bottom of the frame 1, a cutter 803 fastened to the output end of the hydraulic cylinder 802, and a guide seat 804 bolted to the top of the mounting base 801. The guide seat 804 has an inner cavity in the middle for the aluminum rod to pass through laterally.

[0071] In this embodiment, when the straightened aluminum rod passes through the inner cavity opened in the middle of the guide seat 804, the timing start cylinder 802 drives the cutter 803 to move up and down. When the cutter 803 moves up, the cutting edge of the cutter 803 will longitudinally cut the aluminum rod, so that the timing start cylinder 802 can drive the cutter 803 to cut the aluminum rod to a fixed length, ensuring that the fixed length aluminum rod can be adapted to the production of the aquarium cleaning brush handle.

[0072] The cutting mechanism 8 for longitudinally cutting aluminum rods includes a protective mechanism to prevent the aluminum rod from flying upwards at the moment of cutting. The protective mechanism includes a limiting pin 807 threadedly connected to one side of the guide seat 804. A sliding sleeve 805 that is sleeved with the limiting pin 807 is slidably mounted on the outer side of the guide seat 804. An anti-loosening spring 808 for pushing the sliding sleeve 805 is mounted on the limiting pin 807. A roller 806 that presses the aluminum rod downwards is movably connected to the inner side of the sliding sleeve 805.

[0073] In this embodiment, when the cutter 803 cuts the aluminum rod used to make the aquarium cleaning brush handle, the upward-moving cutter 803 presses against the roller 806 closest to the cutting edge. At this time, the pressed roller 806 pushes the sliding sleeve 805 laterally, thereby causing one end of the sliding sleeve 805 to compress the anti-loosening spring 808 along the limiting pin 807. Since the roller 806 rolls and abuts against the aluminum rod passing through the inner cavity of the guide seat 804, the clamping of the aluminum rod by the roller 806 can prevent the cut edge of the aluminum rod from bending when the cutter 803 cuts the aluminum rod, and also prevent the aluminum rod from flying upwards during the cutting process.
